This disclosure relates to pillows, and more particularly to improved neck and travel pillows.
Description of the Related Art
Travel pillows are well known for helping people rest or sleep when in a seated or upright position. However, such prior art travel pillows suffer from common drawbacks such as being bulky, trapping heat and moisture between the pillow and the user's neck and head, and generally being unable to adequately or comfortably support the user's head.
For instance, U.S. Pat. No. 6,230,349 to Silver et al. discloses a travel pillow with some of these drawbacks. Little air is allowed to circulate between the pillow and the user's neck with this type of product, often resulting in an uncomfortably hot and sweaty neck. Further, this type of travel pillow may cause the user's head to tilt forward due to a relatively large and thick rear portion that, when contacting the seat, puts pressure on the rear of the user's neck. Finally, this traditional travel pillow shape may fail to provide adequate support for a user's head and neck when the head is in a left, right, or forward position.
The present disclosure is generally directed to travel pillows with features for increased user comfort, with some exemplary features including air or ventilation apertures, an inner pillow frame that is more rigid than an outer cushion at least partially surrounding the frame, and one or more protrusions or chin supports. The present disclosure is also generally directed to clip mechanisms which may include indentations and accompanying protrusions, and/or magnets, for preventing accidental or unintentional disengaging of the clip halves. Some embodiments of the present disclosure may include features for increased adjustment capability and comfort, such as multiple anchor points on each side of the pillow which may be used for engagement of a drawstring mechanism or similar.
One embodiment of a pillow according to the present disclosure comprises a cushion with left and right side portions and a rear portion therebetween. The left side portion may comprise a left forward portion and the right side portion may comprise a right forward portion, and a top of each of the left forward portion and the right forward portion may extend upward to support a user's chin. The left and right side portions may be shaped to define at least one aperture each.
Another embodiment of a pillow according to the present disclosure may include a cushion, with the left side of the cushion having two or more anchor points and the right side of the cushion having two or more anchor points. One half of a connector, such as a drawstring, may be connected to one anchor point on each side, and a closure mechanism may be attached to both or one of the connector halves. A user can choose to engage the second anchor point on each side of the cushion with one of the connector halves in order to adjust the maximum tightening point of the pillow.
One embodiment of a magnetic closure mechanism according to the present disclosure comprises a left portion with an inner protrusion and a magnet therein, and a right portion shaped to define an inner indentation for connection with the inner protrusion. The right portion may include a second magnet for connecting to the first magnet.
These and other further features and advantages of the disclosure would be apparent to those skilled in the art from the following detailed description, taken together with the accompanying drawings, in which:
The present disclosure describes travel pillows for supporting the head of a user, such as when sitting in an airline seat. Different embodiments of neck and travel pillows according to embodiments of the present disclosure may include novel and inventive features for increasing user comfort. Some embodiments of the present disclosure may include one or more air or ventilation apertures which may aid in user cooling, such as by increasing air circulation and preventing or reducing the trapping of warm air by a user's head and/or neck. Other embodiments may include a soft outer cushion with a more rigid inner frame therein. The inner frame can provide for more support than a travel pillow without such a frame, while the softer outer cushion can provide the typical comfort and softness associated with travel pillows. In embodiments also including ventilation apertures, the inner frame may be shaped to define apertures which correspond to apertures in the outer cushion. Some embodiments may include protrusions or chin supports which may be included on the side or leg portions of the pillow. These protrusions can increase support of a user's head and may also be designed so as to avoid contact with areas of a user that are sensitive, such as the front of the neck and the jaw underside. The travel pillow may also include a cover which may be removable. The cover may include air-permeable areas, such as mesh or woven areas, which may be aligned with ventilation apertures such as those described above. Another embodiment of a travel pillow according to the present disclosure may include side portions which terminate at a lower side thereof with an outwardly-extending flared portion such that the lower and/or front sides of each side portion may rest on the user's chest to help support the user's head. Various embodiments of the present disclosure may also include combinations of these features.
Other embodiments may further include a closure mechanism, attachment mechanism, or clip fixed with the side portions of the pillow. The side portions may each include a drawstring aperture at a forward end thereof. One half of the drawstring may be attached, such as on its internal drawstring half end, to each side portion of the pillow through its respective drawstring aperture. At its external end, the drawstring half may be connected to a closure or attachment mechanism half, such as a buckle or clip half. The closure mechanism halves may be connected to one another and their position along their respective drawstring halves adjusted so as to tighten together the side portions of the pillow, which can allow for adjustment to various neck sizes. The closure mechanism halves may be, for example, spring-biased so as to hold their respective positions upon their respective drawstring halves unless a user actuates the closure mechanism to reverse the spring biasing. The closure mechanism may include features for preventing or making more difficult unintentional disengagement of its halves. For instance, the closure mechanism may include male and female mating portions such as indentations and protrusions, and/or may include magnets which engage with one another when the closure mechanism is engaged.
Additionally, travel pillows according to the present disclosure may include additional features to increase user adjustability. For instance, such features may include features which enable the adjustment of the drawstring configuration beyond the adjustment provided solely by the closure mechanism. In one such embodiment, in addition to the primary anchor point where each drawstring half exits the main body of the pillow, each side portion of the pillow may include a secondary anchor point. A user can optionally engage the left anchor point with the left drawstring half and engage the right anchor point with the right drawstring half, which will either allow the pillow fit to be looser or tighter (depending on the positions of the primary and secondary anchor points). In another possible configuration utilizing left and right primary and secondary anchor points, the left drawstring half can be engaged with the right secondary anchor point and the right drawstring half can be engaged with the left secondary anchor point, such as in a “criss-cross” pattern, to provide even further increased support. It is understood that many different embodiments other than those described above, and embodiments including any combination of these and other features, are possible.
The present disclosure is described herein with reference to certain embodiments, but it is understood that the disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. The devices and elements herein may have different shapes and sizes beyond those shown. It is also understood that when a feature or element, such as a layer, region, cover, cushion, frame, or otherwise may be referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present. Furthermore, relative terms such as “inner,” “outer,” “upper,” “above,” “lower,” “beneath,” and “below,” and similar terms, may be used herein to describe a relationship of one element to another. It is understood that these terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures.
Although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of the present disclosure.
Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively. When the word “each” is used to refer to an element, it does not necessarily imply a plurality of the elements, but can also mean a singular element.
Inclusion of ventilation apertures such as the apertures 104 can provide for a travel pillow that is cooler than prior art pillows. Inclusion of the ventilation apertures can allow for air to flow more easily through the pillow 100. Additionally, the relative size of each of the apertures may vary to allow different compression characteristics along the top of the travel pillow, or aperture size may be approximately uniform. For example, the rear portion aperture 104a may be relatively large so that the top side of the cushion at the rear portion 103 may flex more than, for example, areas of the side portions 102a,102b. Alternately, larger apertures towards the front of the side portions can allow for greater air flow and flexing at the front area of the travel pillow, while smaller apertures and more rigid pillars in the back portion can provide for greater support at the back of the user's head. Pillars 107 defined between adjacent apertures 104 may be provided to control flexion of the top portion of the outer cushion and/or inner frame, improve support of the user's head, and/or provide for a wide range of sizes. Some embodiments of travel pillow apertures which may be used in embodiments of the present disclosure are described in commonly assigned U.S. patent application Ser. No. 15/125,095 to Wong (a joint inventor of the present application), which is fully incorporated by reference herein in its entirety.
The pillow 100 may comprise an outer cushion 160 and an inner frame 150 (shown here in broken line as it is internal to the outer cushion 160). The outer cushion 160 may comprise any material including but not limited to traditional travel pillow materials, and in one specific embodiment comprises foam such as memory foam or polyurethane foam. The inner frame may be harder, more rigid, and/or denser than the outer cushion (although it is understood that in other embodiments the outer cushion may be harder, more rigid, and or denser, and that still other embodiments may not include a distinct inner frame). The inner frame may be made of any rigid or semi-rigid material, such as, for example, plastic, metal, composite materials, or foam such as memory foam.
For example, in one embodiment the inner frame and outer cushion are made of foam or other material. In one such embodiment, the inner frame material has a density between 50 kg/m3 and 600 kg/m3. In a more specific embodiment, the inner frame material has a density between approximately 150 kg/m3 and 500 kg/m3. In a further specific embodiment, the inner frame material has a density between approximately 300 kg/m3 and 400 kg/m3. And in one specific embodiment, the inner frame material has a density of approximately 350 kg/m3. The outer cushion 160 may also have a range of densities. In one embodiment, the outer cushion has a density between approximately 10 kg/m3 and 200 kg/m3. In a more specific embodiment, the outer cushion has a density between approximately 60 kg/m3 and 120 kg/m3. In a further specific embodiment the outer cushion has a density between approximately 75 kg/m3 and 105 kg/m3, and in one specific embodiment the outer cushion has a density of approximately 90 kg/m3. It is understood that the exemplary densities listed above for inner frames and outer cushions according to the present disclosure are applicable both to embodiments where both of these elements are made of foam or a similar material, and to embodiments where only one of the two is made from foam or a similar material. It is further understood that embodiments with densities outside these ranges are possible.
In one particular embodiment, both the inner frame 150 and the outer cushion 160 are made from foam such as memory foam, but with different densities. The foam density of the inner frame 150 may be higher than the density of the outer cushion 160. In one embodiment of the present disclosure, a travel pillow includes an inner frame that is at least 1.5 times as dense or rigid as the outer cushion. In another embodiment, the inner frame is at least twice as dense or rigid as the outer cushion. In another embodiment, the inner frame is at least three times as dense or rigid as the outer cushion, or at least four times as dense or rigid. In another embodiment, the inner frame is between 1.5 and 10 times as dense or rigid as the outer cushion, or is between two and six times as dense or rigid as the outer cushion, or is between three and five times as dense or rigid as the outer cushion, or is approximately four times as dense or rigid as the outer cushion. Utilization of a more dense or rigid inner frame such as the inner frame 150 may allow the design of the outer cushion 160 to be focused more upon contact comfort (i.e., the comfort of the material as it contacts the user or a user's clothes), since the inner frame 150 can provide structural support which normally would have to be provided solely by the outer cushion 160.
In embodiments of pillows according to the present disclosure that include both an inner frame/outer cushion arrangement and ventilation apertures, such as the pillow 100, the apertures of the inner frame and outer cushion may be at least partially (and in some instances completely) aligned with one another to allow air flow through the entire width of the side or rear portion of the pillow through which the aperture is disposed. Some embodiments of inner frame/outer cushion arrangements which may be used in embodiments of the present disclosure are described in commonly assigned U.S. patent application Ser. No. 15/125,095 to Wong, which is fully incorporated by reference herein in its entirety.
The pillow 100 may also optionally include a closure mechanism, attachment mechanism, clip, or buckle 112 (referred to herein simply as a “closure mechanism,” although it is understood that many different embodiments are possible), which may include closure mechanism halves 112a,112b that can engage with one another. The closure mechanism halves 112a,112b may be connected to the remainder of the pillow 100 by a connection mechanism such as a drawstring 106 including drawstring halves 106a,106b. It is understood that while the specific embodiment shown in
In one embodiment, the side portions of the inner frame 150 and the outer cushion 160 each include a drawstring aperture 118 at the forward end thereof, respectively. The drawstring 106 may traverse the drawstring apertures of each side portion. Each of the drawstring halves 106a,106b may attach to the body of the pillow 100 at an anchor mechanism, such as the anchor mechanisms 110a,110b, although it is understood that many different closure mechanisms are possible. For example, in one embodiment the drawstring halves 106a,106b could each loop through a pillow aperture such as one of the apertures 104, and in another embodiment the drawstring halves 106a,106b could attach to the remainder of the pillow 100 without an anchor mechanism.
The position of each of the closure mechanism halves 112a,112b along its respective drawstring half 106a,106b can be adjusted upward so as to tighten the side portions 102a,102b toward one another. In one embodiment, the closure mechanism halves 112a,112b may be spring-loaded or similar, and/or may be biased to a “locked” position at a location along a drawstring half 106a,106b until actuation of a device, such as the push-buttons 108, which may be spring-loaded. Upon actuation, the closure mechanism halves 112a,112b can be “unlocked” and can be slid along their respective drawstring half 106a,106b to a new position. It is understood that the location of the closure mechanism halves 112a,112b can be adjusted when separate, and can be adjusted when engaged with one another. In some embodiments, the pillow side portions 102a,102b can be tightened such that they are nearer each other, and in one embodiment may be tightened such that they touch one another.
Travel pillows described herein and according to the present disclosure, including but not limited to the travel pillow 200, may have side portion cross-sections such as the cross-sections of the side portions 202,204 that are generally vertically-oriented. The height and width of side portions according to the present disclosure may vary at different points of the side portion due to the pillow's ergonomic shape, such that the side portion has a maximum height that is greater than its minimum height (as opposed to having a uniform height where the maximum height and minimum height are equal). In some embodiments, side portions may have a smaller height toward their rear and a larger height toward the front (as shown in
The width of side portions according to embodiments of the present disclosure, such as the side portions 202,204, may also either be uniform or vary. In some embodiments, the average width of the side portion may be between about 0.5 inch and 4 inches, and in one specific embodiment between about 1 inch and 3 inches, and in an even further specific embodiment between about 1.5 inches and 2.5 inches. Many different embodiments in and outside of these ranges are possible.
Side portions according to embodiments of the present disclosure may be approximately straight vertical, or may be angled. For example, as best seen in
As best seen in
The pillow 200 may include an indented portion 208 having some characteristics similar to the indented portion 105 shown in
Air or ventilation apertures 210 may be included through the side portions 202,204 and/or rear portion 206 of the pillow 200. The apertures 210 may have some characteristics similar to the apertures 104 shown in
Further, the inclusion of an indented portion such as the indented portion 205 may result in less material being used, which can lower the weight and cost of the pillow. While as shown the apertures 210 are included in the first and second side portions 202,204 and the rear portion 206, it is understood that many different air aperture placements are possible, such as through side portions only, through the rear corners of the pillow 200 between the side portions and the rear portion, through the rear portion only, and any combination thereof.
Pillars 207 may be provided between adjacent apertures 210, and can provide mechanical support. The pillars 207 may be similar to or the same as the pillars 107 described above. In embodiments utilizing an inner frame, the pillars 207 may include material from both the inner frame and outer cushion, just the inner frame, or just the outer cushion. In other embodiments, pillars according to the present disclosure may include a third material, which may be more rigid than both the outer cushion and the inner frame material. The combination of pillar and aperture design may be designed to provide a desired flexion profile to a user. Additionally, the area between pillars can serve as “flexion zones” while the areas corresponding to pillars can serve as stiffer areas, thus providing the user with different flexion profiles in different areas of the pillow which he or she can utilize as desired. Many different embodiments are possible.
Apertures in embodiments of the present disclosure may have various different shapes. For example, apertures such as the apertures 210 and those described elsewhere herein may be circular, square, polygon-shaped, oval, triangular, plus-shaped (e.g., intersecting vertical and horizontal apertures), L- and inverted-L-shaped, T- and inverted-T-shaped, or any other regular or irregular shape. Many other different shapes are possible. Further, while in
Additionally, such apertures may also have many different sizes. Pillows according to the present disclosure may include apertures having a width or a height, and in some cases both, from about 0.1 inch to about 6 inches, and in a further specific embodiment about 0.25 inch to about 4 inches, in an even further specific embodiment about 0.5 inch to about 2.5 inches, and in yet an even further specific embodiment about 0.75 inch to about 1.75 inches. Pillows according to the present disclosure may include apertures having a width or a height, and in some cases both, of 0.1 inch or greater, and in a specific embodiment 0.25 inch or greater, and in a further specific embodiment 0.5 inch or greater, and in a further specific embodiment 0.75 inch or greater, and in an even further specific embodiment 1 inch or greater, and in one specific embodiment 1.5 inches or greater. Pillows according to the present disclosure may include apertures having a width or height, and in some cases both, of about 6 inches or less, and in a specific embodiment 4 inches or less, and in a further specific embodiment 2.5 inches or less. Pillows according to the present disclosure may include one or more apertures having an area of 0.25 square inch or more, 0.5 square inch or more, 0.75 square inch or more, 1 square inch or more, 1.25 square inches or more, or 1.5 square inches or more. As shown with regard to
The indented portion 208 is shown as running approximately centrally height-wise through the outer surfaces of the first and second side portions 202/204 and rear portion 206. Similarly, the apertures 210 are shown as centered approximately halfway up the outside surfaces of the pillow 200. This vertical placement can increase ventilation in that a space (or spaces) may remain between the apertures 210 and the neck of a user, as opposed to an embodiment where an air aperture is, for example, directly against a user's jaw or neck. Designing the pillow 200 such that a space remains between the inner opening of the ventilation apertures and a typical user's neck can aid in ventilation by increasing air circulation, whereas if no space remains air may become stagnant within an aperture against a user's skin. It is understood that the vertical placement of the indented portion 208 and/or apertures 210 may be higher or lower than the specific embodiment shown as would be understood by one of skill in the art. For example, vertical placement of the indented portion 208 may vary between embodiments designed for users with longer necks (higher indented portion and aperture placement) versus users with shorter necks (lower indented portion and aperture placement). In some embodiments of the present disclosure, the bottom of one or more of the apertures 210 may be between about 0.25 inch to 2.00 inches from the bottom of the outside surface of the pillow 200 beneath the aperture. In some embodiments, one or more of the apertures 210 may be between about 0.50 inch to 1.50 inches from this point, and in a specific embodiment may be between about 0.75 inch to 1.25 inches, and in yet a further specific embodiment may be about an inch from this point.
As shown in
The chin supports 270a,270b may take the form of protrusions at least partially from an upper surface 202c,202d of the left and right side portions 202,204. Additionally, the chin supports 270a,270b may be on surfaces other than an upper surface of a cushion, as shown by the portions 271a,271b of the chin supports 270a,270b that are inside of and/or on an inside surface of the side portions 202,204. Such an arrangement may have greater chin support stability compared to embodiments where chin supports are attached only to a top surface. Many different embodiments are possible.
The chin supports 270a,270b may be arcuate and may be designed to abut and support a user's jaw. The top of the chin supports 270a,270b may be defined by an arc or a spline curve from rear to front or from side to side (i.e., from top to bottom and from side to side, respectively, as shown in
By fitting to a user's jaw, the chin supports can help to increase user comfort, such as by providing more support to the chin or jaw, or by providing a comfortable feel to the user. In one embodiment, the chin supports 270a,270b may include indentations therein (not shown), such as in an upper surface thereof. These indentations may help to fit the chin supports to the user's jawline. Additionally, the chin supports 270a,270b as they approach their front may be angled inward toward the center of the pillow 200 (as best seen in
The height provided by the chin supports 270a,270b as compared to embodiments without chin supports may provide distinct advantages. For example, the chin supports 270a,270b may be shaped so as to contact the corner or outside of a user's jaw. By contacting the corner or outside of a user's jaw, the chin supports may avoid the jaw underside or neck of a user, which are typically more sensitive areas. In this manner, the chin supports can help to avoid discomfort. It is understood that chin supports according to the present disclosure may be sized and angled in any number of manners.
In some embodiments, the protrusions or chin supports 270a,270b may run along the majority of the left and right side portions 202,204, as shown in
By elevating the chin supports higher than the upper portions of the pillow, the portion of a user that potentially may contact the upper portion of the pillow, e.g. the chin, may contact the chin supports first. Therefore, the inclusion of elevated protrusions or chin supports 270a,270b can enable the use of a softer material, as the increased height provided by the chin supports will provide additional support for a user's chin or jaw. As such, in some embodiments the protrusions or chin supports may comprise a material that is less dense than the remainder of the pillow or outer cushion. This less dense material may be more comfortable after a user's chin has been contacting it for some time, such as the length of extended travel. However, it is understood that the material used for the chin supports may use any number of materials and may comprise a material that is less dense, more dense, or the same density than the material used in the remainder of the pillow or the outer cushion of the pillow.
In some embodiments of the present disclosure, the chin supports 270a,270b may be approximately 0.25 inch to 3.00 inches high, or more specifically about 0.5 inch to 1.5 inches high. In other embodiments, the chin supports 270a,270b may be about 0.75 inch to 1.25 inches high, or may be approximately 1 inch high. The chin supports 270a,270b can be approximately 2 inches to 10 inches from back to front (as shown in
In addition to the added support described above, the inclusion of chin supports can also result in other benefits. For example, the inclusion of chin supports such as the chin supports 270a,270b can further reduce the pillow's user contact area, thus reducing the chances of overheating and resulting in a cooler pillow as described above with regard to side portion design. The combination of the inclusion of chin supports and the previously-described side portion design, including but not limited to side portions which angle outward from top to bottom and/or which are wider at their base than at their top, can have particularly beneficial cooling effects, and can result in an even further-reduced user contact area.
Embodiments of pillows according to the present disclosure may also include closure mechanisms such as the closure mechanism 280, and connectors such as the connectors 282, such as drawstring halves. These elements will be discussed in detail below.
Embodiments of pillows and cushions according to the present disclosure may include covers, such as flexible covers.
The cover 330 may include an airflow portion 332. The airflow portion 332 may comprise an air permeable material, such as a mesh material or other type of material that enables the flow of air into and out of the pillow 330. In other embodiments of the present disclosure, an airflow portion may include no material so as to provide the maximum airflow. The airflow portion 332 may be placed in an area approximately corresponding to or at least partially overlapping with an indented portion such as the indented portion 308, and/or in an area approximately corresponding to or at least partially overlapping with apertures such as air or ventilation apertures 310, such that the airflow portion 332 is over one or more of the apertures 310. In other embodiments, the entire cover 330 may be a highly air permeable material such as mesh. Many different embodiments are possible.
Use of covers such as the cover 330 may also alter the shape and appearance of the pillow itself. For example, the cover 330 causes the curves of the pillow 300 shown in
Many different chin support shapes other than those shown in
Chin supports such as protrusions or chin supports 270a,270b and 470a,470b may be used for purposes other than support of the outside of a user's chin. For example, in the embodiment shown in
Pillows according to the present disclosure may be manufactured using many different methods. In one embodiment of a manufacturing method according to the present disclosure, an inner frame of the pillow (typically comprising denser and/or more rigid material than the outer portion) is molded and cured. After curing, the outer portion may be molded thereover. The molding of the inner and outer portions of the pillow may be done so as to include air apertures therein. In another embodiment, neither of the inner frame and outer cushion are molded to define apertures, and any material in the proposed aperture area may be removed automatically or manually. In another embodiment, only one of the inner frame and outer cushion is molded to define one or more apertures, and any material in the proposed aperture area of the other may be removed. Many different methods are possible.
The cross-sectional shape of the side portions may be shaped so as to enhance user comfort over conventional travel pillows. In conventional travel pillows, the portion abutting a user's neck often contacts or pressures a user's trachea, which can cause discomfort. Embodiments of pillows according to the present disclosure, however, may be shaped so as to prevent this contact or pressure.
Angling of upper side portion cross-sections away from a user, such as the angling of the upper side portion 654, may serve additional purposes. For example, users may adjust the pillow such that the inner surfaces of the pillow, such as the inner surface 654a, are against a user's chest, as described above. The angle of the inner surface 654a removes material which typically would bunch against the user's chest and cause discomfort. Additionally, as previously described with respect to side portion shape and the inclusion of chin supports, the angling of the upper side portion away from a user's neck can result in a lower user contact area, thus providing an increased cooling effect. This type of cross-section can also result in benefits with regard to the support provided by the pillow, in that because less material is present or bunched against the user, the pillow is capable of a further range of user adjustment to find a comfortable configuration.
As discussed above, pillows according to the present disclosure may include inner frames which can provide support, serve as shock absorbers, and provide a desired flexion profile to a user. One example of a frame 700 according to the present disclosure and which can be used in embodiments of pillows according to the present disclosure is shown in
Inner frames such as the frame 700 shown in
Embodiments of the present disclosure may also include a layer between inner and outer cushions, with such a layer preventing or reducing the possibility of tearing of the inner frame. Such a layer may comprise cloth, nylon, rubber, fibrous materials, cross-hatched materials, or other materials, and may be arranged in a pattern to reduce the possibility of tearing, such as a cross-hatch arrangement. Such materials or layers could also be within inner frames, or within outer cushions, according to embodiments of the present disclosure.
As discussed above with regard to
In the specific embodiment shown in
In the embodiment shown, the drawstring halves 812a,812b may be aligned with and placed through the channel 801 defined by the anchor mechanism 800 until they are on the rear side thereof, and the stops 814a,814b can then be turned so as to no longer be aligned with the channel 801, such as being turned perpendicularly to the channel 801 as shown in
Use of anchor mechanism and drawstring combinations such as that shown in
Use of anchor bases such as the anchor base 850 can aid in preventing ripping of the pillow to which the anchor mechanism is attached. An anchor base may have an area larger than the material that would otherwise be resting against the remainder of the pillow, such as a stop such as the stop 814a. This larger area can spread the force caused by a user pulling upon the connector (e.g., a drawstring half) over a larger pillow area, thus reducing the chance of ripping or tearing.
Anchor mechanisms according to the present disclosure may be connected to pillows, such as to inner frames and cushions, at drawstring apertures which may be placed through a forward portion of the side portions thereof (although other placements are possible). The anchor mechanism may include ends having a diameter larger than the aperture so as to secure the anchor mechanism to the frame and/or cushion. For example, in the embodiment shown on the left of
The anchor mechanism 800 may be attached at an inner surface of the pillow inner frame 802 (
As discussed above with regard to
When the left and right closure mechanism portions 902,904 are connected (as shown in
The closure mechanism 900 may include inner portions that interact with, or otherwise mate with, one another so as to form a secure connection between the left and right fasteners 902,904. Many different inner portion designs are possible, and it is understood that different outer portion designs may be used with different inner portion designs and vice versa.
In other embodiments, magnets may be placed within the left and right closure mechanism portions 1002,1004, so as to secure the connection therebetween. It is understood that many different magnet configurations are possible. As shown in
The closure mechanism 1000 may also be designed so as to enable easy connection between the left and right closure mechanism portions 1002,1004. For instance, the primary body of the left closure mechanism portion 1002 may include an outer protrusion 1032, and the primary body of the right closure mechanism portion 1004 may include an accompanying outer indentation, similar to the protrusion/indentation arrangement 902a,902b,904a,904b as shown in
The protrusion 1012 may include a post 1016a and the indentation 1014 may include a post aperture 1016b (although it is understood that this may be reversed such that a protrusion is shaped to define a post aperture and an indentation is shaped to define a post). In the embodiment shown, the post 1016a is included at an outer end of the protrusion 1012 and the post aperture 1016b is included on an inner end of the indentation 1014. However, it is understood that these components may also be located elsewhere along the protrusion 1012 and indentation 1014, respectively. When the left closure mechanism portion 1002 and right closure mechanism portion 1004 are connected, the post 1016a and post aperture 1016b can mate. The arrangement of the post 1016a and post aperture 1016b can prevent or make difficult the disconnection of the left and right closure mechanism portions 1002,1004 via horizontal force. This can result in the prevention of unintentional disconnection of the left and right closure mechanism portions 1002,1004.
Posts according to the present disclosure, such as the post 1016a, may take many different shapes. Accordingly, post apertures such as the post aperture 1016b may take an accompanying shape. For example, the post 1016a includes a chamfer on its inner upper corner. Posts according to the present disclosure may include chamfers on the upper outer corner, which can increase ease of connection. Additionally, post corners may be tapered or curved inward to ease connection. For example, in the specific embodiment shown, the post 1016a includes sides that taper inward. Rounded shapes, such as rounded corners or fillets, may also be used instead of chamfers. It is understood that the present disclosure may include many different shapes.
Further, the cross-sectional plan view of protrusions such as the protrusion 1012 may also vary. For example, in the embodiment shown in
In the specific embodiment shown, the protrusion 1012 may also include a secondary post 1018a on its inner portion, which in this embodiment is connected to the primary body 1002a. The indentation may include a corresponding secondary post aperture 1018b adjacent the primary body 1004a. The secondary post and aperture 1018a,1018b can serve to better secure the connection between the left and right closure mechanism portions 1002,1004, such as by prevention of disconnection via twisting of the closure mechanism 1000. It is understood that other embodiments of the present disclosure may or may not include the secondary post and aperture 1018a,1018b or similar features.
In other embodiments, one or more posts may be included in the indentation 1014 and one or more post apertures may be included in the protrusion 1012, or vice versa. Furthermore, while the post 1016a is shown as rectangular and including a chamfer on its corner, many different shapes are possible. For example, rounded post shapes or a post shape with outward angles can result in easier disconnection for the user, whereas a post shape including 90° corners or inward angles can result in a more secure connection. Zig-zag or sawtooth connections are also possible. Many different mating configurations are possible according to the present disclosure, and the above examples are in no way limiting.
In other embodiments of the present disclosure, a magnet may also serve as a post, such as a post that can prevent or make difficult horizontal disconnection of left and right closure mechanism portions. In one embodiment, the magnets 1020a,1020b are flush with the top surface of the protrusion 1012 and the bottom surface of the indentation 1014 as shown in
Closure mechanism portions such as the left and right closure mechanism portions 1002,1004 may be designed to be disconnected in any number of ways. For example, the closure mechanism portions 1002,1004 are designed to make difficult detachment via horizontal force, but designed such that detachment via vertical force is comparatively much easier. As another example, the closure mechanism portions 1002,1004 and the inner portions thereof may also be designed such that detachment via downward force on the middle of the closure mechanism 1000 or via upward force on the left and right portions (as shown in
Additionally, closure mechanism portions 1002,1004 can be disconnected via force applied to connectors such as drawstring halves which are connected to the closure mechanism 1000. For example, when the closure mechanism 1000 is placed in the same position as the closure mechanism 112 in
While some of the above specific embodiments have included magnets, other closure mechanisms are also possible, including but not limited to snap closure mechanisms which may include a release button, button closure mechanisms, loop closure mechanisms, and other types of mechanical and nonmechanical closure mechanisms. Many different embodiments are possible as would be understood by one of skill in the art.
Pillows according to the present disclosure may include various different styles of anchoring systems, many of which can allow for user customization to allow for a better fit. These anchoring systems may be used with connectors, such as drawstrings, and a closure mechanism or similar; some examples of these elements and systems have been described above. These anchoring systems may use many of the same or similar components to those described above, including but not limited to components described or shown with relation to
In the specific embodiment shown, the travel pillow includes three anchor points 1102,1104,1106 where a drawstring half 1108 may exit or be attached to the body 1110 of the pillow 1100 (or a component thereof, such as an outer cushion, cover, etc.). It is understood that embodiments according to the present disclosure may include any number of attachment openings and/or anchor points, for example one, two or four, or even more. The drawstring half 1108 may be detachable from the pillow body 1110, and can be reattached so as to have the same or a different anchor point. The pillow 1100 may be designed such that attachment of the drawstring to bottom- and/or forward-most anchor point 1102 (as shown in
The anchor points 1102,1104,1106 are shown in
Other embodiments including user adjustable anchor systems are also possible.
The pillow 1200 also includes a secondary anchor point 1208 which can provide for user adjustability. While other embodiments are possible, in the embodiment of
Further, while the embodiment of
As with all embodiments herein, the pillow 1200 may also include a cover. In the specific embodiment shown, the pillow 1200 includes a cover 1205. As shown in this embodiment, the secondary anchor point 1208 is accessible from outside the cover 1205 such that a user can engage it without removal of the cover 1205. One example of attachment of a connector within the cover 1205 is shown with regard to
Forces applied to connectors such as drawstring halves may in some instances cause force upon a pillow that could cause damage to the pillow body, such as tearing or ripping. Embodiments of the present disclosure may also include reinforcement mechanisms such as a reinforcement mechanism 1210 which can prevent ripping or other damage which may be caused by the forces upon the secondary anchor point 1208. In the embodiment shown the reinforcement mechanism 1210 wraps around a top surface of the pillow 1200, although many different embodiments are possible. Such reinforcement mechanisms may also be utilized around primary anchor points.
Reinforcement mechanisms according to the present disclosure may also be used in between anchor points.
The pillow 1300 also utilizes a different style of secondary anchor point than the secondary anchor point 1208 from
As best shown in
Some embodiments of the present disclosure, such as embodiments including primary and secondary anchor points, may utilize double-anchor mechanisms, where the anchor mechanisms used at two different anchoring points are combined into a single mechanism.
As with single-anchor mechanisms, each of the single-anchor components 1902,1904 may include an anchor base 1952 and a protrusion 1954 such as a tube which may include a larger diameter on the end to prevent accidental disengagement with an aperture. A connector such as a drawstring half 1960 may include a stop 1962 which can engage or nest with an anchor base or an anchor base backside such as the anchor base backside 1952a, which may be shaped to receive the stop 1962.
The single-anchor components of a double-anchor mechanism, such as the single-anchor components 1902,1904 of the double-anchor mechanism 1900, may be connected at any desired angle in order to meet the design of the remainder of the pillow in which they are to be used. For example, single-anchor components may be connected at an angle between 0° (in line with one another) and 90° (at a right angle to one another); in a further specific embodiment between 0° and 60°; and in an even further specific embodiment at an angle between 0° and 45°. In yet another embodiment the single-anchor components may be connected at an angle between 0° and 30°; in a further specific embodiment at an angle between 0° and 15°; and in yet a further specific embodiment at an angle between 0° and 7.5°. Additionally, while the double-anchor mechanism 1900 includes untwisted single-anchor components 1902,1904, double-anchor mechanisms according to the present disclosure may be twisted with respect to one another. Many different embodiments are possible.
Further, the type of connection between single-anchor components such as the single-anchor components 1902,1904 may vary. In one embodiment, the double-anchor junction 1906 is rigid such that the single-anchor components 1902,1904 are prevented from moving with respect to one another, which provides the strongest prevention against bunching. Double-anchor mechanisms with a movable double-anchor junction are also possible. In another embodiment, the double-anchor junction 1906 is able to rotate in one or more planes such that the single-anchor components 1902,1904 can rotate with respect to one another, which can keep the single-anchor components at an approximately equal distance from one another and can lessen the chance of breakage of the double-anchor junction. Many different embodiments are possible, and the above examples are in no way limiting. Further, it is understood that while only a double-anchor mechanism 1900 is shown, mechanisms including three or more anchors are also possible. Further, while the double-anchor mechanism shows a primary anchor 1902 and a secondary anchor 1904, it is understood that any primary/secondary anchor combination is possible. The use of single anchors for some or all anchor points is also possible.
