1. Field of the Inventions
The present inventions relate generally to eyewear and more specifically to eyeglass and goggle frames, having improved comfort and fit.
2. Description of the Related Art
A wide variety of improvements have been made in recent years in the eyewear field, particularly with respect to eyewear intended for use in active sports, including goggles and sunglasses. These improvements have been incorporated into eyewear and goggles having both dual and unitary lens designs. As a result, modern active sport eyewear is functionally superior to its predecessor eyewear in numerous ways, such as by maximizing interception of peripheral light, reducing optical distortion, and increasing the wearer's comfort level.
For example, lens designs for both dual and unitary eyewear and goggle designs can provide full side-to-side range of vision and good lateral eye protection while providing superior optical performance. More particularly, in a unitary lens system, the angle of incidence from the wearer's eye to the posterior lens surface changes as the wearer's line of sight turns in either the vertical or the horizontal planes. This results in disparate refraction between light entering closer to the front of the lens and peripheral light entering at the side portions. To address this source of prismatic distortion, U.S. Pat. No. 4,859,048 discloses tapering the thickness of the lens from the central portion toward the side edge, the entirety of the disclosure of which is incorporated by reference herein.
Further, various improvements have also been made in goggle lens frame technology that allow mounted lenses to retain their superior optical characteristics provided by their as-molded geometry. For example, the “SPLICE” snow goggle manufactured by Oakley, Inc., incorporates a frame design that mitigates bending stresses along the bridge of the goggle in order to allow the lens to retain its as-molded geometry and maximize the comfort for the wearer. Such systems are disclosed in U.S. patent application Ser. No. 12/359,175, titled Controlled Deflection Goggle, filed Jan. 23, 2009, the entire disclosure of which is incorporated herein by reference.
Finally, numerous modifications have been made to eyeglass and goggle products in an effort to make these products more comfortable for the wearer. For example, different materials have been used in the manufacture of frames and lenses in order to decrease the weight and improve the comfort of these products. These technological improvements can be incorporated into any variety of dual or unitary lens designs, whether for eyeglass or goggle products, in order to provide a wearer with a comfortable, optically superior eyewear product.
Further features and advantages of the present invention will become apparent to those of skill in the art in view of the detailed description of preferred embodiments which follows, when considered together with the attached drawings and claims.
A goggle is a semi-customizable eyewear product that can be adjusted to fit a wearer's head by adjusting a strap of the goggle. Further, an eyeglass can also be customized to the wearer through adjusting the fit and/or components of the eyeglass for achieving a desired function. Goggle and eyeglass applications include skiing, snowboarding, motocross, aquatics, and a variety of industrial safety applications, among others. Typically, goggles offer sealed protection to the eyes and adjacent areas of the wearer's face against particulate matter or water. Generally, the goggle and/or lens conforms closely to the wearer's face and intercepts light, wind, dust, etc. from directly in front of the wearer and peripherally along the sides. A wearer can adjust the elastic strap of the goggle to conform closely to the face of the wearer during use. Various features and structures of eyewear are disclosed herein. Some of these features and structures are disclosed in the context of goggles. For sake of brevity, the embodiments and discussion will not generally be repeated with respect to eyeglasses. However, the discussion of a given feature of a goggle herein is contemplated as being applicable to eyeglasses as well.
A goggle usually comprises an arcuate unitary lens which extends across both of the wearer's right and left eye fields of view. The lens can be supported by a frame, which typically surrounds the lens. The lens and the frame are both configured with a downwardly concave indent or nosepiece opening for receiving the nose. The rear surface of the frame, normally covered with a foam component or other compressible material, is adapted to contact the wearer's face. Further, the elastic strap is connected to the opposing sides or ends of the frame so that the wearer can fit and wear the goggle on their head.
When worn, the surface of the foam component or other compressible material disposed at the rear of the goggle makes contact with the wearer's face. This wearer-contacting surface has a radius of curvature in the horizontal plane that is adapted to conform from side to side of the wearer's face. However, some embodiments reflect the realization that when the goggle is placed on a wearer with a “narrow” head, the tension from the straps extending around the back of the wearer's head can cause the sides of the goggle to bend inwardly toward a center thereof, thereby wrapping the goggle into a tighter radius of curvature to fit the wearer and distorting the optics of the goggle. Further, the central portion of the goggle can become substantially compressed against the wearer's forehead while a gap is formed between the sides of the goggle and the wearer's temples. Other poor fit or discomfort problems can occur when a goggle is placed on a wearer with a “wide” head or when the goggle is worn over a helmet.
Thus, some embodiments reflect the realization that the lens of a goggle can sometimes experience undesirable distortion when the goggle is fitted to a wearer's unique head profile. This distortion can sometimes cause discomfort for the wearer as well as inferior optical performance of the eyewear product. Various embodiments enable the eyewear product to exhibit enhanced structural properties in order to prevent discomfort and to maintain preferred optical characteristics of the eyewear product.
Further, some embodiments reflect the realization that a customizable goggle system can be far more effective and useful to a wearer than prior art goggles because a wearer's needs and preferences may change from time to time. Thus, in some embodiments, the goggle can comprise an interchangeable goggle and goggle system in which a lens support or anterior module can be interchangeably coupled with a faceplate or posterior module. In some embodiments, the goggle and goggle system can also comprise at least one connector that couples the anterior module to the posterior module. The components of such a goggle and system can be interchanged in order to create a goggle having desired optical and physical characteristics. For example, the wearer can interchange one or more components of the goggle in order vary the rake, internal air volume, articulation, lens configuration, fit, comfort, and other such optical and physical characteristics of the goggle.
Further, some of the embodiments reflect the realization that prior art goggles tend to create uneven pressure distribution across a variety of wearers' heads. Thus, in some embodiments, the goggle can be configured such that the posterior module of the goggle can articulate relative to the anterior module in order to self-adjust over a variety of unique facial contours and head sizes in order to provide a customized fit to the wearer. In some embodiments, the goggle can comprise an isostatic mechanism or suspension mechanism in which one or more connectors allow the posterior module to articulate with respect to the anterior module. For example, the posterior module can be coupled to the anterior module using any of a variety of connectors, such as wishbone connectors, straight links, expandable cells, pivotable couplings, rigid couplings, and the like.
Additionally, some of the embodiments reflect the realization that prior art goggles generally caused deflection of the lens when the goggle is fitted onto the head of the wearer. Accordingly, in some embodiments, the goggle can be configured such that the anterior module comprises a generally rigid component or portion such that bending stresses exerted on the anterior module are withstood when the goggle is being worn. Thus, the lens of the goggle can be maintained in its as-molded configuration when in use, thereby preserving the optical quality of the lens. In some embodiments, prismatic shift or other optical distortions are minimized when in use.
Furthermore, some of the embodiments reflect the realization that prior art goggles do not facilitate interchangeability of lenses absent a significant stress or force to remove or replace the lens. Thus, in some embodiments, the goggle can comprise an interchangeable lens mechanism that allows a lens to be interchanged with and retained by the goggle. For example, the anterior module of the goggle can comprise one or more pockets or clips that can operate to retain one or more of the edges or sides of the lens. The lens can be retained by the interchangeable lens mechanism such that the lens “floats” or is secured to the anterior module without being bended from its as-molded configuration. Thus, the optical qualities of the lens can be preserved.
One or more of the features discussed herein can be incorporated into embodiments of the goggles. As such, any variety of combinations of these features can be provided as will be apparent to one of skill in the art.
Moreover, in some embodiments, a goggle is provided that can comprise a lens support or anterior module and a faceplate or posterior module. The lens support can be adapted to support at least one lens in a wearer's field of view. The faceplate can be flexible and adapted to conform to the contours of a wearer's face. In some embodiments, the lens support or anterior module can be interchangeably connectable with the faceplate or posterior module to modify at least one physical characteristic of the goggle.
In some embodiments, the faceplate can be coupled to the lens support such that when the goggle is worn by the wearer, opposing ends of the flexible faceplate move in a direction opposite to a direction in which a central portion of the faceplate moves when a force is exerted on one of the opposing portions and the central portion of the faceplate. Further, in some embodiments, in response to a force, the opposing ends of the flexible faceplate can move away from the opposing ends of the lens support while a central portion of the faceplate moves toward a central portion of the lens support. Further, the side portions of the faceplate can move generally independently of each other.
Some embodiments can comprise a suspension assembly that can comprise one or more suspension members or connectors that interconnect the flexible faceplate with the lens support at respective suspension points. In some embodiments, the at least one connector can be interchangeable with the lens support and the faceplate.
For example, the suspension members can enable pivotable movement of the faceplate relative to the lens support at the respective suspension points to modify a contour of the faceplate relative to the contour of the wearer's face. The suspension members can be substantially incompressible. The suspension members can comprise one of a wishbone connector, a curved or straight link connector, an expandable cell connector, and other such components. One or more suspension members may also be positioned in a manner that allows rolling or a “seesaw” effect as it responds to pressure on the frame. The goggle can optionally comprise at least one elongate link member coupled to the faceplate adjacent to each of the respective suspension points. The link members can be coupled to the respective suspension members and to the faceplate for imparting rotation at a first part of the goggle to a second part of the goggle for moving the opposing ends of the faceplate in an opposite direction of the central portion thereof.
Further, the goggle can be optionally configured such that the suspension members comprise a pair of upper suspension members interconnecting an upper portion of the flexible faceplate with an upper portion of the lens support. The suspension members can also comprise a pair of lower suspension members interconnecting a lower portion of the flexible faceplate with a lower portion of the lens support. In such embodiments, the upper suspension members can be coupled to the faceplate and the lens support at locations generally symmetrically spaced from a center point or center line of the faceplate, such as adjacent to side portions thereof. Further, the lower suspension members can be coupled to the faceplate and the lens support at locations generally symmetrically spaced from a center point or center line of the faceplate, such as adjacent to side portions thereof.
Further in some embodiments, the goggle can optionally comprise at least one elongate link member coupled to the faceplate adjacent to each of the respective suspension points. The link members can be coupled to the respective suspension members and to the faceplate for imparting rotation at a first part of the goggle to a second part of the goggle for moving opposing ends of the faceplate in an opposite direction of the central portion thereof.
In embodiments comprising the suspension assembly, the goggle can optionally be configured with the suspension assembly coupling the flexible faceplate to the lens support such that movement of the central portion of the flexible faceplate toward the central portion of the lens support causes separation of the opposing portions of the faceplate from opposing portions of the lens support when the goggle is worn by the wearer. In such embodiments, the suspension assembly can comprise one or more suspension members.
Moreover, some embodiments of the goggle can be configured to comprise a generally rigid lens support or anterior module. The generally rigid lens support or anterior module can support a lens in the wearer's field of view while preventing substantial bending or optical distortion of the lens.
Additionally, the goggle can optionally comprise an interchangeable lens mechanism that facilitates removal and retention of a lens relative to the lens support or anterior module of the goggle. The interchangeable lens mechanism can comprise one or more pockets and/or clips that can engage with a portion of the lens for retaining the lens relative to the goggle.
In some embodiments, the goggle can comprise a pair of outriggers that each outrigger comprises a pair of fastening portions configured to interconnect the anterior module with the posterior module. The fastening portions can be attachable to the anterior and posterior modules at coupling regions thereof. The anterior and posterior modules of the goggle can be coupled together by the outriggers and without the use of specialized tools, single-use fasteners or permanent fasteners. In some embodiments, the outriggers can function as the primary mode of coupling or attachment means between the anterior and posterior modules, such as between a lens support and a faceplate. However, a secondary mode of coupling or attachment means can be employed, such as snap-fit members, hook and loop members, and/or other types of interference fit or frictional engagement members. These secondary connectors can be used in combination with the outriggers to couple the anterior and posterior modules together. In particular, these secondary connectors can be used as an initial coupling mechanism to hold the anterior and posterior modules together as an assembly while the outriggers are attached or detached from the assembly. Thus, the overall assembly, including the outriggers and other components discussed herein, can enable a wearer to quickly manipulate an interchange any given component of the assembly.
Further, the outriggers can each further comprise a pin member extending from a body thereof. In such an embodiment, the anterior module can comprise a pair of apertures that are configured to receive the pin members of the respective outriggers when the outriggers are coupled to the anterior and posterior modules. The combined interconnections of the pin members and the fastening portions of the outriggers can thus provide a fixed rotational position of each outrigger relative to the anterior module. Additionally, the posterior module can comprise apertures configured to receive the pin member when the outriggers are coupled to the anterior and posterior modules. In some embodiments, the coupling regions of the anterior module comprise a recess. For example, the recess can be configured to receive the fastening portions of the outriggers.
Some embodiments of the goggle can comprise a latch member that is coupled to the anterior module. The latch member can be rotatable between an open position in which a lens can be inserted or removed from the lens support and a closed position in which the lens is secured to the lens support. The goggle can also further comprise a biasing member coupled to the latch member. The biasing member can provide a biasing force tending to urge the latch member toward the closed position. The biasing member can be rotatably coupled to the latch member, and in some embodiments, the biasing member can also be rotatably coupled to the anterior module. Thus, in some embodiments, an outrigger can comprises a pin member extending through corresponding apertures in the biasing member and the latch member, and the pin member can provide an axis of rotation for the biasing member and the latch member.
In accordance with some embodiments, the goggle can comprise at least one port disposed along the periphery of the lens support. The port can provide an airflow passage for introducing air over an interconnecting portion of the goggle for improving ventilation and reducing fogging of the goggle. For example, the port can exhibit Venturi airflow characteristics. In some embodiments, the goggle can comprise a pair of ports disposed at the central portion of the lens support above the lens of the goggle.
The above-mentioned and other features of the inventions disclosed herein are described below with reference to the drawings of the preferred embodiments. The illustrated embodiments are intended to illustrate, but not to limit the inventions. The drawings contain the following figures:
While the present description sets forth specific details of various embodiments, it will be appreciated that the description is illustrative only and should not be construed in any way as limiting. Additionally, although particular embodiments of the present inventions may be disclosed or shown in the context of unitary or dual lens eyewear systems, such embodiments can be used in both unitary and dual lens eyewear systems. Further, various applications of such embodiments and modifications thereto, which may occur to those who are skilled in the art, are also encompassed by the general concepts described herein. Furthermore, although various embodiments are shown in use with goggles, embodiments can also be used with eyeglasses and other forms of eyewear.
Some goggle embodiments are provided that overcome many of the disadvantages of the prior art, such as preferential bending, poor comfort, and optical distortion of the lens. Various embodiments are provided that can improve the overall comfort and fit of the goggle on a wide range of head geometries. Some embodiments are configured such that the goggle can actively self-adjust to the head geometry of a given wearer using an isostatic suspension mechanism. Some embodiments are configured with a rigid lens support such that the goggle can prevent bending of the lens and thereby prevent optical distortion. Further, some embodiments can comprise a lens retention mechanism that enables a lens to be quickly removed and replaced with another given lens. Various mechanisms and features for providing one or more of these advantages can be incorporated into various embodiments of the goggle.
Prior Art Goggle Design and Use
The foam component 16 is intended to contact the wearer's face and allow the goggle 10 to conform to the surface of the wearer's face. However, gaps frequently form between the foam component 16 and the surface of the wearer's face due to the preferential bending of the goggle 10. Furthermore, certain portions of the foam component 16 can often be highly compressed while other portions are not compressed at all. In this regard, the foam component 16 will fail to properly distribute stresses along the surface of the wearer's face resulting in stress concentrations along the front or side of the wearer's head, such as along the forehead, temples, and cheekbones. Some embodiments reflect the realization that such stress concentrations are created due to the preferential bending of the goggle frame 12 and the poor adaptability of the goggle frame 12 to various head sizes.
When the goggle frame 12 and the lens 20 are bended to the loaded position, the goggles 10 generally exhibit preferential bending at a midpoint 28 of the lens 20. Some embodiments reflect the realization that a disadvantage of such preferential bending at the midpoint 28 of the lens 20 creates bending of the frame 12 at the nosepiece 18. As shown in
Additionally, the preferential bending also causes the centers of curvature of the side portions 22, 24 of the lens 20 to be significantly displaced from the common center of curvature A to the displaced centers of curvature B, C. The central section 26 of the lens 20 is also significantly deformed from its unloaded position. This deformation of the lens 20 substantially worsens the original or as-molded optical characteristics of the lens 20.
For example, the lens 20 can exhibit substantial prismatic shift and other optical distortions that tend to tire the eyes of the wearer and reduce the wearer's ability to accurately perceive the position of objects. These disadvantages may not only make use of the goggle 10 uncomfortable, but can potentially affect the wearer's performance of a given activity. In fast-paced activities, such as skiing, snowboarding, skydiving, motocross and the like, where goggles are commonly used, the disadvantages caused by preferential bending of the lens 20 and the frame 12 can be exacerbated.
With regard to
Interchangeable Component Goggle Embodiments
Some embodiments reflect the realization that in many situations, the goggle 10 may bend as it is fitted onto a wearer's head, thus resulting in deformation of the lens 20, a poor fit that creates uneven pressure and discomfort across the wearer's head, and/or reduced anti-fogging capabilities. Additionally, some embodiments reflect the realization that the orientation of the goggle 10 with respect to the wearer's line of sight may be difficult to precisely adjust. Thus, the wearer may be at a disadvantage in performing activities in which vision could be enhanced by precisely adjusting the orientation of the lens (such as the “rake” of the lens).
Accordingly, some embodiments provide a manner for improving the comfort, fit, optical quality, anti-fogging, and/or customization and interchangeability of components of a goggle. Some embodiments can provide a goggle that includes an anterior module or lens support that can be interchanged with a posterior module. For example, one or more anterior modules (or lens supports) can be interchangeable with one or more posterior modules (or faceplates, which can be fitted against the face of a wearer).
Some embodiments can provide a goggle that includes an isostatic faceplate configured to provide uniform pressure distribution of the face-contacting portion of the goggle against the face of the wearer across a range of head sizes. Such embodiments can mitigate uneven pressure distribution by allowing differential adjustability of a posterior module relative to an anterior module of the goggle.
Some embodiments can also provide a goggle in which the anterior module or lens support is operative to support the lens of the goggle in an undeflected or optically preferred orientation to optimize the optical qualities of the lens. For example, at least a portion of the anterior module or lens support can be substantially rigid to prevent bending of the lens. Further, some embodiments can provide a goggle at having a quick release lens mechanism.
These and other features can be incorporated into a single goggle or used independently of each other to provide for a plurality of distinct goggle embodiments.
Some embodiments of the goggle can comprise separable components that can be interchangeably used in order to customize the goggle to the wearer's preferences. In some embodiments, the goggle can comprise separable components that can be interchangeably used to modify a mechanical and/or cosmetic feature of the goggle.
For example, separable components can be interchangeably used to modify at least one of the “rake” of the lens, the enclosed air volume capacity within the goggle, structural relationship between the anterior module and the posterior module, the articulation between the anterior module and the posterior module, the biasing of the posterior module, the fit of the goggle, and other mechanical and/or cosmetic features.
The components of the goggle can be interchangeable or replaceable with other components. The posterior module 104 can be configured to be interchangeable and removably attachable to the anterior module 102. One or more anterior modules 102 can be interchanged with a plurality of posterior modules 104 in order to provide a variable and customizable configuration depending on user preferences. Further, a common anterior module 102 can be interchangeable with one of a variety of posterior modules 104. For example, the goggle 100 can be configured such that the wearer can interchange components of the goggle 100 in order to adjust the goggle 100 to modify a fit between the anterior module 102 and the posterior module 104, a configuration of the anterior module 102 and/or the posterior module 104, and/or an interconnection between the anterior module 102 and the posterior module 104.
As noted above, the goggle 100 can comprise the connector(s) 106. The connector(s) 106 can releasably or permanently couple the anterior module 102 with the posterior module 104. The connector(s) 106 can comprise either a movable or fixed component that interconnects the anterior module 102 with the posterior module 104. The connector(s) 106 can extend partially or completely around a perimeter of the anterior module 102 and/or the posterior module 104.
The configuration of the connector(s) 106 can be modified or interchanged to directly influence the fit between the anterior and posterior modules and/or the manner in which the posterior module and/or the anterior module functions in the goggle. The configuration of the connector(s) 106 may be varied while the configuration of the posterior and/or anterior module remains constant. In some embodiments, both the configuration of the connector(s) 106 and the configuration of the posterior and/or anterior module can be varied. The connector(s) 106 can also be configured in a variety of different connection modes and purposes. Thus, in this and other embodiments disclosed and discussed further herein, the movement of the posterior module can be performed substantially independently of movement of the anterior module. Thus, in embodiments, the posterior module may flex and be shaped to the face of the wearer to maximize comfort and fit while the anterior module is maintained in a substantially undeflected state, thus avoiding optical distortion of a lens (whether dual or unitary) supported by the anterior module.
For example, the connector(s) 106 can be configured to provide a rigid, stationary, or fixed relationship between the connector(s) 106 and the anterior and/or posterior modules 102, 104. In such embodiments, the connector(s) 106 can establish a spacing, position, or orientation of the posterior module 104 relative to the anterior module 102. Further, the connector(s) 106 can be interchanged to modify the spacing, position, or orientational relationship between the anterior and posterior modules 102, 104.
Further, in some embodiments, the connector(s) 106 can also be configured to provide a flexible, movable, rotatable, translatable, or pivotable relationship between the connector(s) 106 and the anterior and/or posterior modules 102, 104. For example, the connector(s) 106 can be coupled to the anterior module 102 and to the posterior module 104 in a manner that allows the connector(s) 106 to move or rotate relative to at least one of the anterior module 102 and the posterior module 104. In this manner, the connector(s) 106 can enable the posterior module 104 to flex, move, rotate, translate, or pivot relative to at least one of the anterior module 102. In this manner, the goggle 100 can provide an independent suspension or isostatic mechanism that can equalize or evenly distribute the pressure of the goggle along and against the areas at which the goggle contacts the face of the wearer. The independent suspension or isostatic mechanism can provide differential adjustability of the posterior module relative to the anterior module in order to equalize pressure distribution exerted by the posterior module against the head of the wearer.
Further, in some embodiments, the connector(s) 106 can be interchangeable with the goggle 100 in order to provide a different connection mode and/or a customizable configuration depending on wearer preferences. For example, different embodiments of the at least one connector(s) 106 can be interchanged with the goggle (such as shown in the embodiments shown in
The connector(s) 106 can be formed separately from the anterior and posterior modules 102, 104. The connector(s) 106 can be removable from the goggle and interchangeable in order to allow the wearer to adjust a given characteristic of the goggle. Further, the connector(s) 106 can be coupled to one of the posterior module 104 and anterior module 102 in a manner that allows relative movement between the connector(s) 106 and at least one of the posterior module 104 and the anterior module 102. In some embodiments, the ends of the connector(s) 106 can be attached to the anterior and/or posterior modules 102, 104 by means of thermal bonding, adhesive bonding, mechanical engagement, and/or other coupling methods known in the art. Various embodiments are shown in
However, in some embodiments, the connector(s) 106 can also be monolithically formed with either of the anterior or posterior modules 102, 104.
The connector(s) 106 can also comprise one or more subcomponents, for example, that can articulate with respect to each other to provide an articulating connector(s) 106. Further, the connector(s) 106 can be formed from various types of materials, for example, to provide rigidity, flexibility, compressibility, or other desirable mechanical or material characteristics. Thus, the connector(s) 106 can comprise pivotable links, rigid links, flexible bodies, leaf springs, coil springs, rigid bodies, compressible bodies, rod-shaped bodies, wishbone-shaped bodies, diamond-shaped bodies, gaskets, and/or expandable cells.
In some embodiments, the goggle 100 can comprise a single connector 106. For example, a single connector 106 can be in the form of a gasket, pad, or other unitary structure that extends about the periphery of the anterior and posterior modules 102, 104 and interconnects the anterior and posterior modules 102, 104. Further, in some embodiments, the goggle can comprise multiple connectors 106.
As shown in
The anterior and posterior connection points 108, 110 can be formed in a variety of configurations. For example, in the illustrated embodiment of
In some embodiments, the configuration of the anterior and posterior connection points 108, 110 can be modified to directly influence the manner in which the connector(s), the posterior module, and/or the anterior module function in the goggle. In some embodiments, the configuration of the anterior and posterior connection points 108, 110 may be the only variable while the configuration of the posterior and/or anterior module remains constant. In some embodiments, both the configuration of the posterior and/or anterior connectors and the configuration of the posterior and/or anterior module can be varied.
Referring to
As discussed below, embodiments of a goggle system can be provided in which at least one of the anterior module 102, the posterior module 104, and/or the connector(s) 106 can be selectively interchangeable by the wearer to customize at least one of the characteristics of the goggle.
In some embodiments, the goggle system can comprise a plurality of components, connectors, anterior modules, and/or posterior modules having different geometric characteristics that can induce a desired “rake” in the goggle. For example, the goggle system can comprise a plurality of posterior modules 104 having different geometric characteristics that induce a desired “rake” in the goggle. The “rake” of the goggle generally refers to the orientation of the lens relative to a vertical line. An adjustment in the rake of the goggle can allow the wearer to adjust an optical centerline of the lens such that the optical centerline is displaced away from a normal straight-ahead line of sight toward an activity-specific line of sight of the wearer.
For example, some embodiments can allow the rake of the goggle to be customized for activities in which the wearer frequently gazes downwardly relative to the straight-ahead line of sight (to view the path immediately in front of the wearer) or upwardly relative to the wearer's straight-ahead line of sight. By adjusting the optical centerline to correspond more closely to the activity-specific line of sight, the wearer can minimize image shift or prismatic distortion that occurs when the wearer's gaze (i.e. the activity-specific line of sight) passes across the lens. This can be advantageous for sports that require quick reaction times and frequent monitoring of the terrain in front of the wearer, such as downhill skiing, snowboarding, motocross, and the like.
The rake of the goggle can be adjusted such that the optical centerline of the lens is approximately parallel with the activity-specific line of sight. Further, the rake of the goggle can be adjusted such that the optical centerline of the lens is approximately coaxial with the activity-specific line of sight.
Accordingly, in some embodiments, a posterior module can attach with an anterior module and position the lens from the wearer's head at a different vortex distance than that of another posterior module. In particular, different posterior modules can be interchanged to allow the wearer to induce a different rake in the goggle depending on which posterior module is used. Further, different connectors or anterior modules can also be interchanged to allow the wearer to induce a different rake or to otherwise affect the geometry or spacing of the goggle relative to the wearer's face. The difference in spacing or position can be created due to geometric properties of at least one of the posterior module, the anterior module, and/or connectors between the posterior module and the anterior module.
Some embodiments of the goggle system can comprise a plurality of components, connectors, anterior modules, and/or posterior modules that each result in different air volumes within the goggle in order to adjust the anti-fogging capabilities of the goggle. As will be appreciated, the larger the volume of air within the goggle, the lower the likelihood of fogging of the lens of the goggle under a given set of conditions.
For example, depending on the activity, a wearer may remove and replace a given posterior module with another posterior module that increases or decreases the volume of air trapped within the goggle between the lens and the wearer's face. In some embodiments, the connectors, anterior modules, and/or posterior modules can be configured to adjust the space between the anterior module and the wearer's face, such as by varying thickness of padding, thickness of the body of the posterior module, and/or varying the length and/or size of connector(s) used between the posterior module and the anterior module.
Further, the goggle system can comprise a plurality of different components, connectors, anterior modules, and/or posterior modules that can allow a wearer to select between various types of materials, material or mechanical properties, design features, and sizes. In some embodiments, the connectors or components can be formed to provide a minimal or low-profile goggle appearance. The connectors or components can be configured to provide a minimal overall goggle thickness.
For example, posterior modules can be provided in small, medium, large, and extra large sizes in order to allow a wearer to obtain a tailored to fit for their goggle. Each has dynamic conformability through a range of head sizes or geometries. In some embodiments, the posterior modules can be configured to provide biasing toward a desired default position, such as being biased inwardly (for narrow head sizes), outwardly (for wide head sizes), toward a center thereof, frustoconically, cylindrically, spherically, or toward a standard position (for average head sizes). Thus, a posterior module can be configured to assume an undeflected, biased position from which the posterior module can be deflected when the goggle it is positioned on the face of the wearer. The undeflected, biased position can be selected to improve the fit and conformance of the posterior module for a given head shape.
Further, the posterior modules can also be selected based on the thickness, width, material, and configuration of padding of the posterior module. Moreover, some embodiments can allow wearers to incorporate electronics, such as audio and telecommunication equipment, such as an MP3 player or cell phone into the goggle. For example, the anterior module, the posterior module, the strap, and/or other components of the goggle can support one or more electronic devices for use by the wearer. Thus, embodiments provide for an interchangeable goggle having superior customization and capabilities.
In addition to the interchangeability of the anterior and posterior modules in order to provide customizable geometries and configurations of the goggle, the connector(s) 106, the posterior connection point(s), and/or the anterior connection point(s) can also be modified to allow adjustment the rake, component size, air volume, and/or other characteristics of the goggle. In some embodiments, the size, shape, and/or configuration of the connector(s) 106, the posterior connection point(s), and/or the anterior connection point(s) can be selected in order to modify characteristics of the goggle, such as those discussed above. In some embodiments, at least one of the connector(s) 106, the posterior connection point(s), and/or the anterior connection point(s) can be interchanged in order to modify the rake, component size, air volume, and/or other characteristics of the goggle.
In some embodiments, the wishbone connector 142 can be coupled to the anterior module 102 and to the posterior module 104 in a manner that allows the wishbone connector 142 to move, flex or rotate relative to at least one of the anterior module 102 and the posterior module 104. The goggle 140 can provide differential adjustability of the posterior module relative to the anterior module in order to dynamically conform to the wearer's face and tend to equalize pressure distribution exerted by the posterior module against the head of the wearer.
The wishbone connector 142 can be coupled to the anterior module 102 at at least one point and to the posterior module 104 at at least one point. For example, in embodiments such as that illustrated in
The wishbone connector 142 can be movably or rotatably coupled to at least one of the anterior module 102 and the posterior module 104. In order to provide a movable or rotatable relationship between the wishbone connector 142 and at least one of the anterior module 102 and the posterior module 104, wishbone connector 142 can comprise a flexible or pivotable joint formed at one of the connection points of the wishbone connector 142 and the anterior module 102 and/or the posterior module 104.
For example, the wishbone connector 142 can comprise a pivotable connection point 144. In some embodiments, the pivotable connection point 144 can be configured as a hinge joint or rotatable coupling formed between the wishbone connector 142 and the anterior module 102.
Further, the wishbone connector 142 can also comprise a flexible material that is used to create a flexible or pivotable joint. Such an embodiment is illustrated and discussed below with reference to
In the embodiment illustrated in
The wishbone connector 142 can be configured to impart a desired relative movement between the anterior module 102 and the posterior module 104. As discussed and shown further below with respect to

Isostatic Faceplate Goggle Embodiments
Many prior art goggle designs share the deficiency of allowing preferential bending at a midpoint of the goggle frame as the goggle is tightened on a wearer's head that is narrower than the unstressed lateral edge to edge dimension of the goggle. Such preferential bending creates an inferior fit, reduced optical quality, and may even cause physical and optical discomfort for the wearer. Therefore, some embodiments reflect the realization that the preferential bending of prior art goggle frames can be reduced and/or eliminated in order to enhance the comfort and performance of a goggle, such as that disclosed in copending U.S. patent application Ser. No. 12/359,175, filed on Jan. 23, 2009, titled Controlled Deflection Goggle, the entirety of which is incorporated herein by reference. In addition, some embodiments disclosed herein reflect the realization that a customized fit can be achieved by allowing portions of the goggle to dynamically articulate with respect to each other and actively adjust to contours of the wearer's face without requiring corresponding bending of the lens.
As shown in
In the embodiment illustrated in
The flexible coupling 210 can comprise a resilient material. For example, the flexible coupling 210 can be fabricated using a polymer or metal that is compressible, elastic, and/or soft or semi-rigid. In such embodiments, the flexible coupling 210 can extend between the anterior module 202 and a body 212 of the connector(s) 206 and be rigidly attached thereto such that the flexibility of the flexible coupling 210 facilitates relative movement between the connector(s) 206 and the anterior module 202.
The connector(s) 206 can also comprise a pair of posterior ends 214 that can be coupled to the posterior module 204. The posterior ends 214 can be fixedly or movably attached to the posterior module 204 by means of thermal bonding, adhesive bonding, snap fit or other mechanical engagement, and/or other coupling methods known in the art. In some embodiments, the posterior ends 214 of the connector(s) 206 can be formed as widened attachment elements. As illustrated, the widened attachment elements can be configured to provide an increased contact area between the connector(s) 206 and the posterior module 204 to facilitate attachment of the connector(s) 206 to the posterior module 204. As discussed above with respect to the embodiment shown in
Additionally, the embodiment illustrated in

However, in the embodiment illustrated in
The movement of the posterior module 204 can be at least partially controlled by movement of the connectors 206. In some embodiments, the connectors 206 can be generally rigid bodies. In such embodiments, pivoting or rotation of the connectors 206 can cause one end of the connectors 206 to move generally toward the anterior module 202 while another end of the connectors 206 will move generally away from the anterior module 202. Thus, movement of a portion of the posterior module 204 can immediately cause corresponding movement of another portion of the posterior module 204. For example, a wishbone connector can provide this function. These features and functions can be implemented in any of the isostatic faceplate mechanism embodiments, which can be incorporated into any of the goggle embodiments.
Accordingly, the isostatic faceplate mechanism can provide differential adjustability of the posterior module relative to the anterior module in order to equalize pressure distribution across the wearer's head and to enhance the fit and comfort of the goggle over a wide range of head sizes. In some embodiments, the isostatic faceplate mechanism can cause displacement of portions of the posterior module in response to an applied force.
For example, a portion of the posterior module can adjust in a direction generally toward or away from the anterior module in response to an applied force while another portion of the posterior module adjusts in an opposite direction that is generally away from or towards the anterior module. In some embodiments, if a portion of a first posterior module is urged away from the anterior module due to an applied force (caused for example, while putting the goggles on), at least a second portion of the posterior module can be drawn towards the anterior module (which is reverse the direction of the first portion). In accordance with some embodiments, the deflection of the posterior module to provide conformance of the posterior module along the contours of the face of the wearer can aid in maintaining the orientation of the anterior module and lens of the goggle relative to the face of the wearer in a desired and generally constant orientation.
Further, independent articulation of the posterior module relative to the anterior module can allow the anterior module to support the lens in a generally undeflected orientation, thus enhancing optical performance of the lens. Moreover, in some embodiments that use a rigid anterior module, the flexibility and adjustability of the goggle are not compromised.
The connector(s) 306 can comprise either a movable or a fixed component that interconnects the anterior module 302 with the posterior module 304. The connector(s) 306 can comprise a compressible, an incompressible, a flexible, and/or inflexible material. The top perspective view of

In some embodiments, the isostatic faceplate mechanism can therefore allow self-adjusting of the posterior module of the goggle independent of movement of the anterior module. The movement of opposing ends or sides of the posterior module can be generally mirrored based on the location of an applied force. However, the connectors of the goggle can move independently of each other such that the articulation of one side of the posterior module is different from the articulation of the other side of the posterior module. Although such differences in articulation may be uncommon, this capability of some embodiments of the isostatic faceplate mechanism highlights the superior adjustability and self-customization that can be provided by the goggle.
Further, as shown in
The arms 310 shown in the embodiment of
Additionally, in some embodiments, the arms 310 can comprise a generally resilient or flexible material. The arms 310 can be pretensioned or biased towards a given position. For example, the arms 310 can be biased towards a narrow position such that the arms 310 can be widened when the goggle 300 is worn by a wearer. Biasing of the arms 310 can help in achieving an adequate seal between the posterior module 304 and the wearer's face.
As noted herein, some embodiments can provide for an interchangeable goggle by which a wearer can customize one or more components of the goggle. Some of the features and functions of the components, such as the shape, size, and biasing of the posterior module, the connectors, and the anterior module are a few of the parameters that can be customized through a modular goggle.
For example, a wearer could purchase connector arms were connectors that maintain a desired default orientation of the posterior module relative to the anterior module. Further, a wearer could purchase an anterior module having a desired size or coverage. As discussed further below, various types of connectors can be implemented in embodiments of the goggles.
In contrast to the embodiment illustrated in
Accordingly, while the posterior module 464 can achieve a widened deflected position 480, as shown in
In some embodiments, the size, configuration, and coupling mode of the connector can be selectively configured in order to achieve a desired articulation between the anterior module and the posterior module. As illustrated at discussed above with respect to
Further, one or both of the coupling joints between the connector and the anterior module and the posterior module can be configured to allow the connector to be disengaged therefrom. In this manner, the connector can be selectively replaced with a connector having a desired mechanical attribute. As such, the wearer can customize the goggle to their own specifications.
In some embodiments, the link 512 can be rotatably coupled to both the wishbone connector 510 and the anterior module 502. Further, the link 512 can define a length 514. As shown in
The embodiment illustrated in
For example,
In some embodiments, the first and second radii R1, R2 can be generally equal to each other. In such embodiments, rotational movement of the connector 600 about the pivotal coupling 604 can then create equal displacement of the first and second ends 606, 608, which can result in generally equal and opposite displacement of portions of the posterior module 610 coupled to the respective first and second ends 606, 608 of the connector 600.
However,
In some embodiments, the third and fourth radii R3, R4 can be different distances. As illustrated, the third radius R3 can be approximately doubled the fourth radius R4. However, the third and fourth radii R3, R4 can be selectively adjusted in order to achieve a desired articulation, as described below.
In contrast to the embodiment of the connector 600 shown in
In another embodiment of a connector,
In general, the expandable cell connector comprises at least a first strut 673 which is moveably or rigidly connected to the anterior module 674, and a second strut 675 which is rigidly or moveably connected to the posterior module 676. First strut 673 and second strut 675 may be anterior and posterior sections of a single, arcuate leaf spring. Alternatively, first strut 673 and second strut 675 are separated by a bend or hinge point 677. In the illustrated embodiment, the hinge point 677 comprises a loop of wire, which allows the angle between first strut 673 and second strut 675 to be varied through a wide angular range without exceeding the elastic limit of the material. Suitable materials include any of a wide variety of polymers, and also super elastic metals or spring metals, such as spring steel, Nitinol, Elgiloy and others known in the art.
The expandable cell connector illustrated in
In some embodiments, the leaf spring component 672 can be fabricated from a resilient material, such as a plastic or metal that can be elastically deflected. The leaf spring component 672 can comprise a generally elongate body. The leaf spring component 672 can be separately or monolithically formed with one or more additional leaf spring components 672. Thus, the shape and configuration of the expandable cell connector 670 can vary depending on the number and orientation of the individual components of the expandable cell connector 670.
For example, the body of the leaf spring component 672 can comprise one or more curved portions and one or more straight portions. The body of the leaf spring component 672 can have the shape of a bent pin or a spring. Further, the leaf spring component 672 can be fabricated in the shape of a loop in order to facilitate distribution of compressive forces within the body of the leaf spring component 672.
As illustrated, interior connection points P1, P2 of the first and second connectors 680, 682 are spaced apart at a distance L1 when in the undeflected position 684 and at a distance L2 when in the deflected position 686. Although the actual length of the posterior module disposed between the interior connection points P1, P2 of the first and second connectors 680, 682 may be greater than either distance L1, L2,
In some embodiments, the first and second connectors 680, 682 can be configured and mounted relative to the anterior module such that rotation toward the deflected position 686 causes separation of the interior connection points P1, P2. However, the first and second connectors 680, 682 can be configured and mounted relative to the anterior module such that rotation toward the deflected position 686 causes convergence of the interior connection points P1, P2. In either of such embodiments, the articulation of the posterior module can be manipulated in order to target a desired range of head sizes for that embodiment.

Some embodiments of lens engagement systems are provided in Applicants' copending U.S. patent application Ser. No. 12/648,232, filed on Dec. 28, 2009, titled Eyeglass with Enhanced Ballistic Resistance and U.S. patent application Ser. No. 13/020,747, filed on Feb. 3, 2011, titled Eyewear with Enhanced Ballistic Resistance, the entireties of both of which are incorporated herein by reference. Further, these teachings are believed to apply for goggle and eyeglass technologies. These applications also include other features and aspects of eyewear features, including but not limited to goggle strap technology, the entireties of the related disclosures are also incorporated herein by reference.
In some embodiments, the eyewear can comprise a frame or lens support with at least one engagement section for supporting and engaging a lens.
In some embodiments, the interchangeable lens structure 706 can provide at least one interconnection point or engagement section 710 between the lens 708 and the anterior module 704 where the lens 708 is secured to the anterior module 704. The interchangeable lens structure 706 can comprise a structure that moves relative to the lens 708. The interchangeable lens structure 706 can also comprise one or more stationary structures, which can be used in combination with movable structures to engage the lens 708 to retain the lens 708 in a mounted position.
For example, the interchangeable lens structure 706 of the goggle 700 can comprise at least one engagement section 710. The engagement section(s) 710 can comprise at least one retention socket 720 and/or at least one retention clip 722. Further, the engagement section 710, the retention socket 720, and/or the retention clip 722 can comprise an engagement structure or member such as a depression, recess, receptacle, or socket and/or a protruding portion. In the illustrated embodiment, the retention socket 720 can receive and retain a least a portion of the lens 708 while the retention clip 722 can rotate relative to the lens 708 in order to secure the lens 708 in a mounted position on the goggle 700. As illustrated in
Referring now to
In some embodiments, the retention socket 720 can be formed to comprise at least one engagement member 740 that can be configured to engage with the retention structure 732 of the lens 708. For example, the engagement member 740 of the retention socket 720 can be positioned on an inner, anterior face of the retention socket 720 such that the engagement member 740 can engage the retention structure 732 of the lens 708 from a position anterior to the lens 708. However, the engagement member 740 can also be positioned on an inner posterior face of the retention socket 720 such that the engagement member 740 can engage the retention structure 732 from a position posterior to the lens 708. Moreover, the engagement member 740 can be disposed along an interior lateral side of the retention socket 720 such that a side edge of the first end 726 of the lens 708 can contact and/or engage with the engagement member 740.
Additionally, the retention clip 722 can be configured to engage with the second ends 728 of the lens 708 in order to at least partially constrain the lens 708 against anterior motion. For example, the retention clip 722 can comprise an actuating jaw 744 and an engagement member 746. In some embodiments, the jaw 744 can comprise a retention structure configured to engage with a portion of the lens 708. In the embodiment illustrated in
The engagement member 746 can be formed along a portion of the engagement section 710 of the anterior module 704. For example, the engagement member 746 can be formed along an anterior face of the anterior module 704, such as to extend from a recess formed in the engagement section 710. In some embodiments, the engagement member 746 can comprise at least one protrusion and/or recess configured to engage with the retention structure 732 of the second end 728 of the lens 708. As discussed further below, when the engagement member 746 of the retention clip 722 is engaged with the retention structure 732 of the lens 708, the jaw 744 can be rotated from a disengaged position to an engaged position to constrain movement of the lens 708 relative to the engagement member 746 of the retention clip 722.
Subsequent to alignment of the lens 708 with the retention socket 720 and the retention clip 722, the jaw 744 of the retention clip 722 can be moved from the disengaged position (shown in
For example, the retention structure 732 can be configured to allow the lens 708 to engage with the retention socket 720 at a first rotational position and then to allow the lens 708 to be rotated about a generally horizontal axis until being positioned in a mounted position with respect to the anterior module 704. Once in the mounted position, the first end 726 of the lens 708 can be engaged with the retention socket 720 to prevent side-to-side or anterior-posterior motion of the lens 708. In this manner, the engagement member 740 can resist an anterior force exerted against the lens 708 and thereby prevent substantial movement of the lens 708 relative to the retention socket 720.
The jaw 744 can be rotated, moved, slid, shifted, or translated in order to secure the second end 728 of the lens 708 to the anterior module 704. In some embodiments, the jaw 744 can pivot about a generally horizontal lateral axis and engage at least portion of the lens 708 and at least a portion of the anterior module 704. For example, the jaw 744 can be formed with a U-shaped body that can engage or enclose at least a portion of the second end 728 of the lens 708 and at least a portion of the anterior module 704. The retention structure 732 and the engagement member 746 can be enclosed between anterior and posterior portions of the jaw 744. Further, the jaw 744 can engage anterior and posterior portions of the anterior module 704 and at least a portion of the lens 708.
Thus, the jaw 744 can be rotated to the engaged position such that relative movement between the retention structure 732 and engagement member 746 is prevented. More specifically, with the jaw 744 in the engaged position, the protrusion of the engagement member 746 is unable to exit the aperture of the retention structure 732. Additionally, due to the engagement of the second end 728 of the lens 708 with the anterior module 704, movement or disengagement the first end 726 of the lens 708 with the anterior module 704 will also be prevented. In this manner, the first end 726 and the second end 728 of the lens 708 can be secured relative to the anterior module 704.
In some embodiments, the jaw 744 of the retention clip 722 can be secured in place when moved to the engaged position. For example, the rotatable coupling of the jaw 744 can comprise a recess and protrusion mechanism in which one of the recess and the protrusion rotate relative to the other until the jaw 744 reaches the engaged position, at which time the recess and the protrusion can engage with each other in the mechanism in order to limit or prevent rotational movement of the jaw 744 absent the presence of a significant rotational force. Accordingly, such a mechanism can prevent accidental and unintentional rotation and subsequent disengagement of the jaw 744. Other such mechanisms, including clips, pins, latches, etc., can be incorporated into the retention clip 722 in order to fix the jaw 744 once in the engaged position.
In accordance with another embodiment,
The retention clips 820 can each comprise an engagement member 830, a jaw 832 and a latch 834. The jaw 832 and a latch 834 can be rotatably mounted to the anterior module 804. However, in some embodiments, the jaw 832 and/or the latch 834 can be configured to translate with respect to the anterior module 804 and/or be subsequently attached to the anterior module 804 after the lens 808 is positioned at a mounted position with respect to the anterior module 804.
Similar to the embodiment of the goggle 700, the lens 808 can comprise the first and second ends 840, 842 that each comprise a respective engagement structure 844. The engagement structure 844 can engage or mate with the engagement member 830 of the retention clip 820. The engagement structure 844 can comprise an aperture, and the engagement member 830 can comprise a protrusion. The jaw 832, similar to the jaw 744, can resist relative motion between the engagement structure 844 and the engagement member 830.
The latch 834 can be configured to rotate from an unsecured position to a secured position in which the latch 834 can engage with the jaw 832 in order to prevent accidental or unintentional rotation of the jaw 832. These structures and features of the lens 808 and the retention clip 820 can be modified as discussed above with respect to the lens 708 and the retention clip 722 of the goggle 700; therefore, the discussion of such modifications and features is incorporated herein and will not be repeated for the sake of brevity.
Referring now to
Once the lens 808 is in a mounted position as shown in
In some embodiments, the latch 834 can mechanically engage with the jaw 832 such that accidental or unintentional rotation of the jaw 832 is prevented. For example, the latch 834 can comprise one or more protrusions and/or recesses that can engage with one or more respective recesses and/or protrusions of the jaw 832. Further, the latch 834 can be biased toward the secured position by means of a spring or the like such that a substantial rotational force must be exerted up on the jaw 832 in order to move the jaw 832 from the engaged position towards a disengaged position. In such embodiments, the latch 834 can facilitate the secure engagement of the lens 808 with the anterior module 804.
As mentioned herein, the quick release lens mechanism can be used in combination with an eyeglass as well as a goggle. The structure of such embodiments comprises the quick release lens mechanism described above and used in combination with an eyeglass frame and at least one eyeglass lens. The eyeglass can comprise dual lenses or a unitary lens. Further, the eyeglass frame can comprise full or partial orbitals. Accordingly, the above discussion will not be repeated here for brevity, but is incorporated by reference hereto for use in eyeglass embodiments.
Rigid Frame Goggle Embodiments
The term “substantially rigid structure” can encompass embodiments in which the entire anterior module 900 has a constant flexural strength along the width thereof. The term “substantially rigid structure” can also encompass embodiments in which the anterior module 900 has a variable flexural strength along the length thereof, providing desired rigidity at specific portions thereof.
For example, “substantially rigid structure” can encompass an embodiment in which side sections of the anterior module provide a degree of flexibility while a central section of the anterior module is generally inflexible. In some embodiments, the central section of the anterior module can be generally inflexible along a width that can be greater than or equal to about ⅓ of the entire width of the anterior module and/or less than or equal to about ⅘ of the entire width of the anterior module. Further, the central section of the anterior module can be generally inflexible along a width that can be greater than or equal to about ½ of the entire width of the anterior module and/or less than or equal to about ⅔ of the entire width of the anterior module.
Additionally, the term “substantially rigid structure” can also encompass embodiments in which the anterior module is formed from a rigid material, such as a metal or hard plastic, which is generally inflexible under normal flexural stresses of use and handling. However, the term “substantially rigid structure” can also encompass embodiments in which the anterior module is formed from a resilient or elastic material that allows minimal bending, but returns to a default or original configuration when worn.
In some embodiments, the anterior module 900 can have a configuration or contour that matches the configuration or contour of the lens 902 in its as-molded configuration. Thus, the lens 902 can be rigidly supported by the anterior module 900 such that the lens 902 does not deflect from its as-molded configuration, thereby preserving the optical quality of the lens 902.

In some embodiments, the engagement mechanism 1002 can also comprise a biasing component. The biasing component can be configured to urge the latch member 1020 toward the closed position 1024 to secure the lens assembly 1006 relative to the goggle 1000. Further, the biasing component can operate as a bistable mechanism to urge the latch member 1020 toward either the closed position 1024 or the open position 1026.
As shown in
In the illustrated embodiment, the link 1030 is configured as a monolithic structure. The link 1030 can comprise a deflectable core or body 1044 to enable the link 1030 to provide a biasing force to the latch member 1020. For example, the link 1030 can provide a virtual pivot or living hinge for the latch member 1020. The body 1044 can define a variable profile in order to provide a desired degree of resistance to deflection. For example, the body 1044 can define flattened central section to facilitate bending of the link 1030 and provide a desired degree of resistance to deflection. In some embodiments, central section of the body 1044 can be flattened in a direction generally parallel to a bending axis. Further, the end portions of the body 1044 can be flattened in a direction generally transverse or oblique relative to the bending axis in order to reduce and/or prevent bending at the end portions. The variable profile or tapered dimensions of the link 1030 can allow the body 1044 of the link 1030 to be manufactured from a single material while providing desired strength characteristics. However, in some embodiments, the link 1030 can be configured as a monolithic unit or structure having a generally constant cross-sectional profile along the body 1044 or thereof. In such embodiments, the material forming the link 1030 can be selected to provide desired strength characteristics.
However, in some embodiments, the link 1030 can also be formed from a plurality of materials or separate parts. For example, the first and second ends 1040, 1042 of the link 1030 can be formed from a generally rigid material while the body 1044 of the link 1030 comprises a different material that is generally deflectable in order to allow the link 1030 to provide a desired biasing function.
The link 1030 can be formed from a variety of materials, including plastics, metals, composites, and the like. In some embodiments, the link 1030 can be formed using an injection molding process. Other processes such as overmolding, casting, and the like can be used to form the link 1030, whether as a monolithic structure or an assembly and whether formed from a single material or multiple materials.
Referring again to
For example, a pivot connection point 1060 between the latch member 1020 and the frame 1022 can be positioned relative to the first and second connection points 1050, 1052 so as to cause separation of the first and second connection points 1050, 1052 as the latch member 1020 pivots relative to the frame 1022. For example, the first and second connection points 1050, 1052 can define a linear path and a first direct, linear distance therebetween when the latch member 1020 is in the closed position 1024. As shown in
In some embodiments, the increase in the direct, linear distance between the first and second connection points 1050, 1052 can result in a stretching or deflection of the link 1030 as the first and second connection points 1050, 1052 move apart. The link 1030 can be configured to resist the stretching or deflection and tend to urge the latch member to the closed and/or open position 1024, 1026 as the link 1030 seeks to return to a non-stressed position. Accordingly, the link 1030 can tend to exert a biasing force that urges the latch member 1020 toward the closed and/or open position 1024, 1026.
In some embodiments, the spacing or linear distance of the first and second connection points 1050, 1052 can be generally equal to the linear distance between the apertures of the first and second ends 1040, 1042 of the link 1030 when the link 1030 is in the undeflected or at-rest position (i.e., when the latch member 1020 is in the closed position 1024). However, in some embodiments, the spacing or linear distance of the first and second connection points 1050, 1052 can be generally greater than the linear distance between the apertures of the first and second ends 1040, 1042 of the link 1030 when the link 1030 is in the undeflected or at-rest position (i.e., when the latch member 1020 is in the closed position 1024). Thus, the link 1030 can be in a generally stressed or deflected state when the latch member 1020 is in the closed or open positions 1024, 1026. In such embodiments, a closing or opening force can be continually applied by the link 1030 in order to maintain the latch member 1020 securely in the open or closed position 1024, 1026.

In some embodiments, the body 1090 of the latch member 1020 can also comprise a first flange 1094. The first flange 1094 can overlap the lens assembly 1006 and the engagement member 1072 of the frame 1022 when the latch member 1020 is positioned in the closed position 1024. The body 1090 of the latch member 1020 can also comprise a second flange 1096. The second flange 1096 can be configured to engage a portion of the frame 1022 when the latch member 1020 is in the closed position 1024. Accordingly, the first and second flanges 1094, 1096 can be used to receive at least a portion of the lens assembly 1006 and at least a portion of the frame 1022 by capturing or sandwiching the lens assembly 1006 and the frame 1022 to secure the relative positioning of the lens assembly 1006 and the frame 1022.
Additionally, the body 1090 of the latch member 1020 can comprise a stop mechanism 1098. As shown in
In order to achieve a desired articulation and closing or opening force of the latch member 1020, the spacing and configuration of the components of the engagement mechanism 1002 can be varied. Further, the latch member 1020 and/or the frame 1022 can comprise a locking structure or component 1099. The locking structure 1099 can interact with the frame 1022 to provide an additional securing force between the latch member 1020 and the frame 1022 when the latch member 1020 is in the closed position 1024. For example, the locking structure 1099 can be formed as a protrusion along an edge or surface of the latch member 1020. Further, an engaging portion 1101 of the frame 1022, such as a ledge, protrusion, or recess, can engage with the locking structure 1099 when the latch member 1020 is in the closed position 1024 to secure the latch member 1020 in the closed position 1024.
Although some embodiments can use a single lens, some embodiments can use a lens assembly comprising two or more components and/or lenses. For example,
The gasket 1054 can comprise one or more discontinuities to permit airflow into the gap 1060. However, the gasket 1054 can also extend continuously or unbroken about the periphery of the lenses 1050, 1052 such that the gap 1060 forms a sealed or enclosed pocket of air. The gasket 1054 can comprise a breathable or open cell material that allows air passage through the gasket 1054. Further, the gasket 1054 can comprise a non-breathable or closed cell material that tends to prevent air passage therethrough. In some embodiments, the gasket 1054 can comprise breathable and non-breathable portions.
The gap 1060 created between the lenses can facilitate ventilation, anti-fogging, and/or create an insulative effect by trapping a pocket of air between the outer and inner lenses 1050, 1052. For example, an enclosed pocket of air can maintain an intermediate temperature which, in some conditions, can bridge a temperature differential between the air temperature adjacent the wearer's face and the air temperature outside the goggle.
During use, the inner lens 1052 can be compressed against the goggle frame when the lens assembly 1006 is coupled to the goggle. In some embodiments, the inner lens 1052 can form a seal against the goggle frame to maintain a desired air flow or ventilation through the frame, as discussed below.
Referring now to
In use, air can flow into the anterior end 1104 of the port 1102 and out through the posterior end 1106. The air flow can exhibit the velocity and pressure qualities produced as a result of the Venturi effect. A pressure differential can exist between the outer portions of the goggle and the port(s) 1102. Air can be drawn into the port(s) 1102 and pass over a suspension or interconnection portion 1110 of the goggle 1000. In some embodiments, the interconnection portion 1110 can comprise a foam or air permeable membrane (not shown) that covers the suspension or interconnection portion 1110 to prevent ingress of particulate into the interior of the goggle 1000. The air passing through the port(s) 1102 can pass over the membrane and provide enhanced ventilation and defogging for the goggle 1000. In some embodiments, the Venturi effect can contribute to a negative pressure being created in the interior of the goggle to induce airflow therethrough and reduce fogging. Such embodiments can thus provide improved ventilation and defogging compared to prior art goggles that do not comprise an airflow system.
In embodiments of the goggle having an isostatic posterior frame component 1004, the goggle 1000 can further comprise means for allowing further adjustability of the faceplate to conform to larger or smaller head sizes. For example,
For example, the flexible portion 1130 can be formed as a recessed or curved portion along the faceplate 1120. The flexible portion 1130 can deviate from the curvature on either side of the faceplate 1120. As the faceplate 1120 is flattened to accommodate a wide head size, the flexible portion 1130 can also flatten to allow increased coverage and adjustability of the faceplate 1120. Further, for smaller head sizes, the flexible portion 1130 can collapse into itself to allow the faceplate 1120 to be adjusted to tighter dimensions. Accordingly, the shape of the flexible portion 1130 can allow the faceplate 1120 to adjust to a variety of head shapes and sizes more so than a faceplate without a flexible portion.
Further, in some embodiments, the shape of the flexible portion 1130 can also be used to achieve a desired air flow into the interior of the goggle 1000, as desired. One or more of the flexible portions 1130 can be used for facilitating air flow and/or adjustability of the faceplate 1120.
The isostatic mechanism 1122 can comprise a plurality of connectors 1124 that extend from an anterior portion 1126 of the posterior frame component 1004. The connectors 1124 can be formed from a compressible or flexible material. For example, the connectors 1124 can be deflected such that the faceplate 1120 can be deformed to accommodate a given head shape. The connectors 1124 can be positioned generally equidistant from a centerline of the goggle 1000. As illustrated, the connectors 1124 can be positioned at the upper rim or edge of the goggle 1000; however, the connectors can also be positioned along a lower rim or edge of the goggle 1000.
Additionally, the isostatic mechanism 1122 can be integrally or monolithically formed with the faceplate 1120 such that these components form a single-piece unit. For example, in some embodiments, a desirably flexible material can be used to fabricate both be isostatic mechanism 1122 and the faceplate 1120. This can advantageously reduce the manufacturing time and cost, as well as simplify the assembly process. Accordingly, the goggle 1000 can be easily modularly formed using an economy of individual components that are interchangeable according to wearer preferences, as discussed further herein.
Embodiments of the goggle can also be formed modularly with wearer-interchangeable components that can be interconnected and secured together by using a wearer-actuatable fastener or fastening mechanism. In some embodiments, the wearer-actuatable fastening mechanism can be defined as a fastener or fastening mechanism that can be manually actuated between engaged and disengaged states by the wearer. Wearer-actuatable fasteners or fastening mechanisms may be actuated without requiring the use of specialized tools; however, it is contemplated that basic tools, such as a screwdriver, may be used to facilitate actuation. In some embodiments, a wearer-actuatable fastener or fastening mechanism can be actuated by hand, without tools. Further, some embodiments of the goggle can be modularly interchangeable and secured together without permanent or single-use fasteners, such as adhesives and some mechanical fasteners, including screws, bolts, adhesives, and the like.
For example, the embodiment of
In some embodiments, the outriggers can function as the primary means of coupling or attaching the anterior and posterior modules, such as between a lens support, an isostatic mechanism, and/or a faceplate. However, in some embodiments, a secondary means of coupling or attaching can be employed. A secondary means of coupling or attaching can comprise a snap-fit member, hook and loop member, and/or other types of interference fit or frictional engagement members.
For example, as shown in
These secondary connectors can be used in combination with the outriggers to couple the anterior and posterior modules together. Further, these secondary connectors can be disposed on portions of the anterior and posterior modules that are generally abutting when the anterior and posterior modules are positioned or coupled together as an assembly. In particular, these secondary connectors can be used as an initial coupling mechanism to hold the anterior and posterior modules together as an assembly while the outriggers are attached or detached from the assembly. Thus, the overall assembly, including the outriggers and other components discussed herein, can enable a wearer to quickly manipulate an interchange any given component of the assembly.
Referring to
Further, in some embodiments, the fastening portions 1220, 1222 of the outrigger 1200 can comprise recessed portions 1230, 1232 formed adjacent to sidewalls 1234, 1236. The recessed portions 1230, 1232 and the sidewalls 1234, 1236 can be configured to receive and secure portions of the anterior and posterior frame portions 1022, 1212 together. As shown in
The fastening portions 1220, 1222 can be clamped or snapped onto the anterior and posterior frame portions 1022, 1212 to secure the engagement between the outrigger 1200 and the frame. Thus, in some embodiments, the fastening portions 1220, 1222 can comprise protrusions or recesses that snap against corresponding recesses or protrusions of the anterior and posterior frame portions 1022, 1212. Further, the fastening portions 1220, 1222 can fit tightly over the anterior and posterior frame portions 1022, 1212 to secure them together.
During assembly, the pin 1240 of the outrigger 1200 can be inserted an aperture 1242 of the link 1030 of the goggle 1000 and into an aperture 1244 of the anterior frame portion 1022. The top view of
Once in the assembled position as shown in
The features and structures of some embodiments, such as the substantially rigid anterior module 900, can be incorporated into any variety of goggle embodiments. For example, a substantially rigid anterior module can be used in combination with an isostatic faceplate mechanism. Further, a substantially rigid anterior module can be used in combination with an interchangeable lens structure.
The lens engagement mechanism can operate much like the engagement mechanism described above with respect to
Referring to
In some embodiments, the engagement member 1520 of the retention socket 1510 can be positioned on an inner, anterior face of the retention socket 1510 such that the engagement member 1520 can engage a retention structure (such as an aperture) formed in the lens 1506 from a position anterior to the lens 1506. However, the engagement member 1520 can also be positioned on an inner posterior face of the retention socket 1510 such that the engagement member 1520 can engage a retention structure (such as an aperture) formed in the lens 1506 from a position posterior to the lens 1506.
Additionally, the active restraint 1502 can be configured to engage with a second lateral end 1528 of the lens 1506 in order to at least partially constrain the lens 1506 against anterior motion. For example, the active restraint 1502 can comprise a gate 1530. The gate 1530 can be moved between an engaged position and a disengaged position in order to allow the lens 1506 to be retained or released relative to the frame 1508 of the eyeglass 1500. In some embodiments, the gate 1530 can pivot relative to the frame 1508. In other embodiments, the gate 1530 can slide or translate relative to the frame 1508. The gate 1530 can be attached to the frame 1508 and maintained connected with the frame 1508 while in the engaged or disengaged positions. However, the gate 1530 can also be detachable from the frame 1508 and separable therefrom.
In some embodiments, the active restraint 1502 can further comprise a latch member 1532. As illustrated in
For example, the latch member 1532 can comprise an elongate body having a slot 1540 formed therein. The slot 1540 can be configured to receive a hinge pin 1542 that forms a pivot joint with the frame 1508, the gate 1530, and an earstem (not shown). The slot 1540 can be an elongate slot such that when the pin 1542 is received therein, the pin 1542 can travel between first and second ends of the slot, which can provide relative sliding movement between the pin 1542/frame 1508 and the latch member 1532. For example, the slot 1540 can define a travel distance of between at least about 0.1 inches and/or less than or equal to about 0.5 inches. In some embodiments, the travel distance can be about 0.3 inches. In such an embodiment, the latch member 1532 can slide between at least two positions, such as the locked and unlocked positions mentioned above. In the locked position, the pin 1542 is disposed in a first end of the slot 1540, and in the unlocked position, the pin 1542 is disposed in a second end of the slot 1540. In order to facilitate movement of the latch member 1532, the latch member 1532 can comprise a tab or gripping end that enables a wearer to grip and pull or push the latch member 1532 between the locked and unlocked positions.
The latch member 1532 can also be configured to engage a portion of the frame 1508 for preventing movement of the gate 1530 relative to the frame 1508. The latch member 1532 can comprise an engaging end 1550 having a tooth or projection formed thereon. When in the locked position, as shown in
In some embodiments, the engaging end 1550 can define a slot for receiving the portion 1552 of the frame 1508. The illustrated embodiment of
Further, as illustrated in
Referring again to
Further, in some embodiments, the gate 1530 can comprise a corresponding retention structure 1564 configured to engage with a portion of the lens 1506 and/or a portion of the frame 1508. The retention structure 1564 can comprise a protrusion, slot, and/or recess that that can provide a further engagement of the gate 1530 relative to the frame 1508. For example, a protrusion of the gate 1530 could be snap fitted into an aperture or edge of the frame 1508 to reduce accidental dislodgement of the gate 1530 from the engaged position.
