BACKGROUND OF THE SUBJECT DISCLOSURE
Field of the Subject Disclosure
The present subject disclosure relates to fasteners. More specifically, the present subject disclosure relates to one handed fasteners.
Background of the Subject Disclosure
A significant portion of the general population struggles daily with everyday necessary tasks, including dressing. This portion of the population may have conditions including, but not limited to, injury, disease, aging, amputations, or loss of use or immobility due to stroke, which may cause limited range of motion in one or more bodily joints, muscle tremors and motor function disabilities, and difficulty balancing. These symptoms make it difficult to put on clothing and accessories such as shirts and jackets, pants, shoes and socks, backpacks, and other items.
Many existing fabric fasteners are difficult to operate for persons with limited physical ability including: dexterity, range-of-motion, and hand tremors. Existing closures performing similar functions such as buttons, snaps, and hook-and-loop are either too difficult to use with one hand or present themselves too strongly as an “adaptive” technology, forcing the user to be categorized as disabled in public, which can cause a certain discomfort other than the physical.
The traditional button requires passing a typically round button through a slit hole barely big enough for the button. This type requires two hands, or greater-than-average single-handed dexterity.
Snap buttons similarly require two hands, or above average single-handed strength and dexterity to engage, and a different motion and dexterity to disengage, either with a one-hand ripping motion, or two hand pull-apart motion and dexterity.
Other common types of fasteners also present the same dexterity, range-of-motion, and strength requirements. A magnetic “button” exists, which is simply two opposing magnets sewn into folds of fabric. This is an easy to operate fastener, but is too easily undone, providing very limited fastening security. Magnetic buttons can also unintentionally attach themselves to external objects such as furniture causing wardrobe malfunctions.
SUMMARY OF THE SUBJECT DISCLOSURE
There is a need for devices, systems, and methods which assist in putting on clothing that address the known problems for individuals with movement limitations or disorders.
The present subject disclosure encompasses a novel and innovative clothing fastener system designed to enable individuals with limited hand strength and dexterity to securely fasten and unfasten items. Some examples where a traditional button, snap, zipper or other type of closure might also be used: such as articles of clothing (shirt/pant buttons), footwear, cabinetry, baggage/luggage/cases, accessories, attachment points to hang other items, such as on architectural elements, furnishings, mobility devices, or any place where one wants to close or attach something, requiring only one hand to operate the fastener. The present disclosure generally addresses a solution for the challenges faced by individuals with conditions such as hand tremors, muscle weakness, or other limitations that affect manual dexterity, and more broadly can be used by persons of the general public for convenience, style, and functionality.
The present subject disclosure uses the term, One-Handed Fastener (also referred to as “the OHF” or “OHF”), to introduce a novel family of fasteners with varying methods of operation. Each version of the OHF features a unique mechanism that allows for easy one-handed operation to engage and disengage. Although the term “one hand” is used, the present disclosure is not limited to a single hand, but may be used with two hands, or even just a single finger. The purpose of using “one hand” in its description is simply to signify that the concept is so easy to use that a single hand, or even a single finger, is all that is needed to engage and disengage the fastener.
The present device may be tailored to particular applications, with design and functionality variations not limited to any one particular application. Some examples of OHF may be used in wetsuits and other diving apparatuses. Another example of OHF may be a smart fastener, which can self-engage/disengage, or log and communicate operation cycles. Another example of the OHF may be dust-proof fasteners for military or harsh environment applications. In further examples, the OHF may be a mechanical fastener, with complex internal movements for greater holding force.
The present subject disclosure describes devices, systems, and methods that enable a user to fasten and unfasten a button or other conventional fastening device with a single push or pull action. Many different examples of such one-handed fasteners will be described in the present subject disclosure. The overall concept includes a clamping portion and a captured portion. In some examples, the same push button force to engage the fastening function also disengages the fastening function. In other examples, a push button force is used to engage and a pull force is used to disengage the fastening function. Many examples will be presented, each with its own unique features. But one of ordinary skill in the art would recognize that the features of some embodiments may be substituted or added to another embodiment, without departing from the scope of the present subjected disclosure.
In one exemplary embodiment, the present subject disclosure is a fastener. The fastener includes a first component attached to a first substrate; a second component attached to a second substrate; wherein the first component is adapted to reversibly grip the second component when brought into contact thereto upon application of a first force pushing the first component into the second component; wherein the first component is adapted to detach from the second component upon application of a second force pushing the first component into the second component.
In another exemplary embodiment, the present subject disclosure is a fastener. The fastener includes a first component having a substantially curved outer surface and a rounded edge on its periphery; and a second component attached to a second substrate and having a curved outer gripping edge with a concave surface positioned toward a center of the second component; wherein the first component is adapted to be reversibly gripped by the second component with its concave gripping edge when brought into contact thereto upon application of a first force pushing the first component into the second component; wherein the first component is adapted to detach from the second component upon application of a second force in the same direction of the first force and pushing the first component into the second component.
In yet another exemplary embodiment, the present subject disclosure is a fastener. The fastener includes a first component having a substantially curved outer surface and a rounded edge on its periphery; and a second component attached to a second substrate and having a curved outer gripping edge with a concave surface positioned toward a center of the second component; wherein the first component is adapted to be reversibly gripped by the second component with its concave gripping edge when brought into contact thereto upon application of a first force pushing the first component into the second component; wherein the first component is adapted to detach from the second component upon application of a second force in the same direction of the first force and pushing the first component into the second component

DETAILED DESCRIPTION OF THE SUBJECT DISCLOSURE
The present subject disclosure addresses the challenges of fastening and unfastening garments and personal devices for those with mobility limitations. Although the primary motivation of the present subject disclosure is for aiding those with mobility challenges, those without mobility challenges or disabilities can benefit as well. Thus, the present subject disclosure encompasses examples with a broader application that cover a wider range of uses without being limited to those with disabilities.
Examples according to the present disclosure will now be described more fully with reference to the accompanying drawings. Examples are provided so that this disclosure will be thorough, and will fully convey the scope of those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of examples of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that examples may be provided in many different forms and that neither should be construed to limit the scope of the disclosure. In some examples, well-known processes, well-known device structures, and well-known technologies are not described in detail.
In one example, the OHF may be implemented as an articulating snap, which is a push-off close-and-release fastener. This action is sometimes referred to as a Push-Push type. This device eliminates the need for fine motor skills typically required to manipulate traditional buttons and other closures and fasteners. The OHF, also known as an Articulating Snap, is discreet, durable, and may be integrated into garments, handbag/luggage, shoes, or cabinetry, providing an easy to use, yet secure fastening solution for individuals who face difficulties in manipulating buttons due to physical limitations, and also usable by able-bodied persons as a convenient and stylish interface. In some examples, the OHF may be used in garments required to be waterproof such as wetsuits and other diving apparatuses. In other examples, the OHF may be a smart fastener that self-engages and disengages. In some examples of the OHF, the fastener may log and communicate operation cycles. In other examples, the OHF may be used in dust-proof or dust-resistant environments, such as for military or harsh environment applications. Another example of the OHF may be a mechanical fastener with a complex internal movement for increased holding forces.
The One-Handed Fastener (OHF) system may comprise a clasp mechanism, a captured part, a clamping part, and a cap. In some examples, the OHF system may include supporting components such as magnets, springs, and other aesthetic parts described further below.
The OHF system includes a clasp mechanism. The clasp mechanism may include three main parts, and any number of supporting components. The main components which may be combined or eliminated, modified or repeated may include a captured part, a clamping part, and a cap.
The OHF system includes a captured part or portion. The captured part may be a socket, a protrusion, or any suitable member capable of interfacing with a clamping part, described further below. The captured part may have sub-components such as spring(s), magnet(s), stationary parts, or moving parts, securely fastened to one of the materials, components or objects being fastened together. The method of attaching the captured part varies by application, but may be riveted, sewn, glued, to a substrate, having spiked/pressed/folded clamping, or any other means of attachment.
The OHF system includes a clamping part or portion. The clamping part may be configured as a receiver. In some examples, the clamping part may be attached to the opposing or mating material, components or object being fastened. In other examples, the clamping part may be removably connected with an article. The clamping part may be any part that is capable of receiving the captured part. The clamping component and/or set of clamping components may secure the captured part(s) by clamping around the captured part.
The OHF system may include a cap. The cap may assist with articulating the clamping part. The cap may provide an aesthetic finish to the OHF system. In some examples, the cap is mated to the clamping part on an opposing flange or substrate. In other examples, the cap may be configured as an aesthetic cover, such as a traditional button, a trim piece, a shell, or any other configuration one of ordinary skill in the art would appreciate.
As briefly discussed above, the OHF system may include supporting components. In one example, the supporting component may be one or more magnets. The one or more magnets may be incorporated into any OHF, of any style. The magnet(s) may serve to assist in aligning the captured part and the clamping part.
In another example, the OHF system may include one or more springs. The one or more springs may be incorporated to assist in engaging or disengaging the captured part and the clamping part.
The OHF system may further include any other type of part or component that may be considered aesthetic.
The OHF system may be connected with an object to be fastened. The object may be in any shape or material appropriate to the application. In one example, the object may be a shirt or jacket button that closes across the front of the body, or around the cuff of the wrist. In this example, the object may have as few as two parts/flanges/surfaces to be joined together, but the number of parts/flanges/surfaces is unlimited, as the OHF can be built to scale to suit. Although the OHF system may be configured to attach a plurality of objects, the present disclosure is simplified to two removably connecting at least two surfaces with the OHF, such as overlapping flanges (e.g., shirt; jackets).
The OHF system incorporates an ergonomic design. The OHF is designed to be ergonomically friendly, ensuring comfortable and intuitive operation with minimal effort. The shape, size, and positioning of the clasp mechanism are optimized for ease of use and effective button manipulation.
The OHF system is configured with discreet integration. In some examples, the OHF can be seamlessly integrated into any garment, including shirts, blouses, jackets, pants, and shoes. The OHF may include a discreet design that does not interfere with the overall aesthetics of the clothing.
The OHF system is configured to be durable with a long service life. The OHF system may incorporate materials which are selected for durability, ensuring that the fastener withstands repeated use and maintains its functionality over time when forming each aspect of the OHF system.
FIG. 1 provides an exploded view of one example of the One-Handed Fastener in accordance with the description above. OHF system 100 includes a clamping part 130 and a captured part 170. Cap 110 works attaches to clamping part 130 and captures substrate 110 therebetween. In this example, attachment 190 is a rivet configured to secure the captured part 170 to substrate 102.
The substrate 101, 102 may be, for example, fabric, leather, cloth, natural, or synthetics which may have a pliable and/or deformable property. In a non-limiting example of the OHF system 100 embedded in a jacket, one substate may be one side of the front of the jacket, and the other substrate 102 may be the other side of the front of the jacket, such that the two sides of the jacket are held together by each sides attachment to one portion of the OHF system 100, which then connects together as described in detail in this disclosure.
Clamping part 130 is shown as generally circular with a central aperture 131. Other shapes for the clamping part 130 are also possible and within the scope of the present disclosure. On the periphery of the clamping part 130 are finger extensions/projections (or arms) 132 that project outwardly toward the outer edges of the clamping part 130. Finger projects are flattened 132A near the center of the clamping part 130 and curve inward 132B to form a concave hook at the outer edge of the circular clamping part 130. In between each set of finger projections 132 is recess 133. As shown in FIGS. 1-4, six finger projections are shown, but the clamping part 130 may have more or less than six fingers.
As shown in FIGS. 1-4, OHF system 100 may include a cap 110, which serves to substantially cover the clamping part 130 and the captured part 170. Within cap 110 may be an embedded magnet 111 which serves to mate with rivet 190 and integrated magnetic element 191 to align the clamping part 130 and clamped part 170, as will be described in more detail below. The extended portion 191 of rivet 190 extends through central aperture 171 of the captured part 170 while the embedded magnet 111 extends through central aperture 131 of the clamping part 130. Thus, the two magnetic elements 111 and 191 serve to work together to facilitate alignment of cap 110, clamping part 130, and clamped part 170.
FIGS. 2-4 illustrate a perspective exploded view of the OHF system 100. With focus on FIG. 3, the clamping part 130 includes fingers 132 and voids 133 formed by the fingers 132. The fingers 132 may be configured to deform around the captured part 170 when the clamping part 130 is brought into engagement with the captured part 170. Each of the fingers 132 may have a curved retainer, each configured for surrounding a portion of the captured part 170. As previously described, the captured part 170 may be configured to be attached with a substrate 102 with attachment 190. The attachment 190 may be configured to be received in aperture 118 in the captured part 170.
The OHF system 100 in FIG. 4 is substantially similar to the example shown with respect to FIG. 1 except that the captured part 170 is configured to be sewn or glued with a substrate (not shown), as opposed to riveted.
FIGS. 5-14 show another exemplary embodiment of the present subject disclosure. In this embodiment, OHF system 200 is substantially similar to the one shown in FIGS. 1-4, with many of the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. One difference is that the cap 110 is replaced by a button portion 105 having one or more holes 106.
FIG. 5 shows a perspective view, FIG. 6 shows a front view, and FIG. 7 shows a top view, respectively, of OHF system 200. FIG. 8 shows a front view and FIG. 9 shows a perspective view, respectively, along cross sectional plane A-A shown in FIG. 7. As can be seen in FIGS. 6, 8, and 9, the clamping part 130 has fingers 132 that hook around and snap over the outer ends of the captured part 170. An inner concave portion of the finger 132 matches and mates with the outer convex portion of the outer edge of captured part 170. This is how the clamping part 130 reversibly connects with the captured part 170.
FIG. 10 shows a top view of only the clamping part 130. FIGS. 11-12 show cross-sectional front views of clamping part 130 along plane B-B of FIG. 10, in unpressed and pressed positions, respectively. FIGS. 13-14 show cross-sectional perspective views of clamping part 130 along plane B-B of FIG. 10, in unpressed and pressed positions, respectively. The pressing of the top center portion of clamping part 130 causes a flex in the clamping portion, which either engages or disengages it from the captured part 170, as will be described in more detail below.
FIGS. 15-19 show another exemplary embodiment of the present subject disclosure. In this embodiment, OHF system 300 is substantially similar to the one shown in FIGS. 5-14, with many of the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. The OHF system 300 has thicker components as compared ot the OHF system 200. The thicker fingers 132 provide a longer distance between the outer diameter of the clamping part 130 and the outer diameter of the captured part 170.
FIG. 15 shows a perspective view, FIG. 16 shows a front view, and FIG. 17 shows a top view, respectively, of OHF system 300. FIG. 18 shows a front view and FIG. 19 shows a perspective view along cross sectional plane C-C shown in FIG. 17. As can be seen in FIGS. 18 and 19, the clamping part 130 has fingers 132 that hook around and snap over the outer ends of the captured part 170. An inner concave portion of the finger 132 matches and mates with the outer convex portion of the outer edge of captured part 170. This is how the clamping part 130 reversibly connects with the captured part 170.
FIGS. 20-24 show another exemplary embodiment of the present subject disclosure. FIG. 20 shows a perspective view FIG. 21 shows a top view, and FIG. 22 shows a front view, respectively, of OHF system 300. FIG. 23 shows a front cross sectional view and FIG. 24 shows a perspective cross sectional view, respectively, of OHF system at plane D-D shown in FIG. 21. In this embodiment, OHF system 300 is substantially similar to the one shown in FIGS. 15-19, with the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. The OHF system 300 in FIGS. 20-24 has button 105 attached or adhered to the top portion of the clamping part 130. Further, first substrate 101 is positioned between the button 105 and clamping part. One non-limiting example of fixation between the components is through use of thread, which would pass through thread holes 106. Other fixation techniques are also within the scope of the present subject disclosure. A second substrate 102 is positioned at the bottom portion of the clamped part 170. Adhesives or other fixation techniques may be used, as known to one having ordinary skill in the art. The schematics and technique shown in FIGS. 20-24 allow a user to attach the OHF system to an existing garment, such as a shirt. By sewing the button 105 directly to one substrate (placket), the button 105 being attached to the clamping part 130. The clamped part 170 can then be fixated to the other opposing substrate (placket), thereby allowing the clamping part 130 and the clamped part 170 to be on opposing substrates (plackets) and reversibly connecting together when desired to “button” the shirt.
FIGS. 25-29 show another exemplary embodiment of the present subject disclosure. FIG. 25 shows a perspective view, FIG. 26 shows a top view, and FIG. 27 shows a front view, respectively, of OHF system 300. FIG. 28 shows a front cross sectional view and FIG. 29 shows a perspective cross sectional view, respectively, of OHF system at plane E-E shown in FIG. 26. In this embodiment, OHF system 300 is substantially similar to the one shown in FIGS. 20-24, with the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. The OHF system 300 in FIGS. 25-29 has a 6 hole pattern on the clamping part 130 and captured part 170. The additional holes allow for increased stability and retention and force capacity when sewn to a substrate 101, for example. This additional retention also makes each part more integrated with its adjoining substrate thereby providing more securing force. Additionally, central aperture 131 of clamping part 130 has vertical ridges 135, and central aperture 171 of captured part 170 has vertical ridges 175, that align with corresponding fixating components in their adjacent substrate, thereby creating a more secure connection between the OHF system component and the adjacent substrates.
FIGS. 30-34 show another exemplary embodiment of the present subject disclosure. FIG. 30 shows a perspective view, FIG. 31 shows a top view, and FIG. 32 shows a front view, respectively, of OHF system 300. FIG. 33 shows a front cross sectional view and FIG. 34 shows a perspective cross sectional view, respectively, of OHF system at plane F-F shown in FIG. 31. In this embodiment, OHF system 300 is substantially similar to the one shown in FIGS. 25-29, with the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. Central aperture 131 of clamping part 130 has magnetic components 136, and central aperture 171 of captured part 170 has magnetic components 176. The magnetic components 136, 176 may be press fit, glued, and/or UV cured to be integral with the other OHF parts. They can also be overmolded in the manufacturing process. The magnetic components 136 and 176 assist in guiding the clamping part 130 and captured part 170 together by the attractive force created between the two magnetic components.
Turning to FIGS. 35-39, another example of OHF system 400 is illustrated. FIG. 35 provides a perspective assembled view of one example of the OHF system 400. OHF system 400 includes clamping portion 230 and captured portion 270. In some examples, captured portion 270 may be attached to a substrate (not shown).
FIG. 36 is a front view of OHF system 400 showing captured portion 270 within clamping portion 230. In this example, the captured portion 270 may extend out of the clamping portion 230 when connected. In some examples, captured portion 270 may be attached to the substrate.
FIG. 37 illustrates a top view of OHF system 400. Captured portion 270 includes arms 272 with apertures 274 formed through arms 272. In some examples, captured portion 270 may be unitary. In some other examples, captured portion 270 may be more than one component. In some examples, captured portion 270 may be made of a resilient deformable material such that captured portion 270 may be snapped into communication with clamping portion 230. In some examples, each arm 272 may be configured to deform when a force is applied to captured portion 270 to connect captured portion 270 with clamping portion 230. In some examples, to assist with deformation, apertures 274 may be selectively added to arms 272. In some other examples, arms 272 may be free of apertures 274. In some examples, body 220 of captured portion 270 may have a shape 273 forming a space between each of arms 272, which may be configured to receive thread or other type of fixation device to attach captured portion 270 to a substrate.
FIGS. 38 and 39 illustrate front and perspective cross-sectional views of OHF system 400 taken at plane G-G of FIG. 37. In this example, captured portion 270 may connect with clamping portion 230 through an interference fit. To facilitate an interference fit, clamping portion 230 may include retaining features to hold portions of the captured portion 270. In some examples, clamping portion 230 may include anchor 248 and lip 242. Similarly, captured portion 270 may include features configured to be received by clamping portion 230. In some examples, such as shown in FIGS. 38 and 39, at the distal end of each arm 272 of captured portion 270, fulcrum portion 244 and protrusion 246 may be included. In some examples, anchor 248 may be configured to interface with fulcrum portion 244, and lip 242 may be configured to retain protrusion 246.
To connect captured portion 270 with clamping portion 230, a force may be applied to body 220 of captured portion 270, causing each arm 272 to pivot fulcrum portion 244 against anchor 248, forcing protrusion 246 to swing under lip 242 of clamping portion 230. Lip 242 and anchor 248 may be configured to retain the distal portions of each arm 272, with each arm 272 biasing against anchor 248 and lip 242. In some examples, such as shown in FIGS. 38 and 39, lip 242 may include ramp 243. Ramp 243 may be configured with a slope. The slope of ramp 243 may be configured to contact protrusion 246 of captured portion 270, such that arm 272 will bias and eventually snap into clamping portion 230 to retain captured portion 270 therewith.
FIGS. 40-41 show perspective and top views, respectively, of captured portion 270 having central aperture 271. FIGS. 42 and 43 show perspective and top views, respectively, of button 205 having one or more button holes 206. FIG. 44 shows a side view of button 205 with internal geometry in dashed lines. Projection 207 on the lower side of button 205 mates with aperture 271 of captured portion 270 to secure the button 205 thereto. Not shown is a substrate that may be positioned between button 205 and the captured portion 270.

FIG. 47 shows a front cross sectional view and FIG. 48 shows a perspective cross sectional view, respectively, of OHF system at plane H-H shown in FIG. 46. In this embodiment, OHF system 400 is substantially similar to the one shown in FIGS. 35-39, with the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. In the exemplary embodiment shown in FIGS. 45-48, the captured portion 270 does not have the apertures 274 shown in the prior embodiments. Further, clamping portion 230 has one or more holes 231 for thread and other fixation tools to secure the clamping portion to a substrate or other object.
FIGS. 49-52 show another exemplary embodiment of the present subject disclosure. FIGS. 49-50 show perspective and top views, respectively, of OHF system 400.

In this embodiment, OHF system 400 is substantially similar to the one shown in FIGS. 45-48, with the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. In the exemplary embodiment shown in FIGS. 49-52, the captured portion 270 does not extend all the way around but is comprised of three separate arms 272. Each arm 272 of captured portion 270 mates with a corresponding arm 232 of the clamping portion 230. This embodiment results in less material being used to manufacture the OHF system 400.
FIGS. 53-57 show another exemplary embodiment of the present subject disclosure. FIGS. 53-55 show perspective, top, and side views, respectively, of OHF system 400.

In this embodiment, OHF system 400 is substantially similar to the one shown in FIGS. 49-52, with the same components and features so they will not be repeated again for sake of simplicity. Some of the differences will be highlighted. In the exemplary embodiment shown in FIGS. 53-57, the captured portion 270 does not extend all the way around, but is comprised of two non-identical separate arms 272. Each arm 272 of captured portion 270 mates with a corresponding similarly shaped arm 232 of the clamping portion 230. This embodiment results in less material being used to manufacture the OHF system 400.
FIGS. 58-62 show another exemplary embodiment of the present subject disclosure. FIGS. 58-60 show perspective, top views, and side views, respectively, of OHF system 400. FIGS. 61-62 show side and perspective cross sectional views of OHF system 400 at plane L-L shown in FIG. 59. In this embodiment, OHF system 400 is substantially similar to the one shown in FIGS. 58-62, with the same components and features so they will not be repeated again for sake of simplicity. In the exemplary embodiment shown in FIGS. 58-62, a button 205 is shown fixed to the captured portion 270. As with the prior embodiment, the captured portion 270 does not extend all the way around but is comprised of two non-identical separate arms 272. Each arm 272 of captured portion 270 mates with a corresponding similarly shaped arm 232 of the clamping portion 230. This embodiment results in less material being used to manufacture the OHF system 400.
FIGS. 63-65 show another example of the OHF system 500. FIG. 63 provides an exploded view of the OHF system 500. OHF system 500 includes clamping portion 330, captured portion 370, and a resilient element such as, but not limited to, a spring or formed spring steel identified as 350. In FIG. 65, spring element 350 is not shown compressed as it may be in the captured, fastened, or engaged state of the system. In some examples, an additional component 305, such as a button, may be attached to captured portion 370 for functional and/or aesthetic purposes. All components described herein may vary in shape, thickness, geometry, and/or material to achieve the necessary function.
In order to engage or fasten clamping portion 330 with captured portion 370, a force is applied to 370 while the two components are aligned. The retaining features of clamping portion 330, identified as 342 in FIG. 65, flex outward to accommodate each arm 372. At the same time, spring element 350 compresses as captured portion 370 moves toward clamping portion 330. Once a sufficient force is applied, captured portion 370 will be attached to clamping portion 330 via a snap fit interaction at each of the legs 372. Captured portion 370 is held in tension in this engaged state by opposing forces within the resilient spring element 350 between clamping portion 330 and captured portion 370. This subject disclosure is not limited to the geometry or configuration here shown, but, using the same engagement and release, may be configured in various geometries, materials, and/or orientations.
To disengage, unfasten, or release captured portion 370 from clamping portion 330, a force is applied to 370 in the same direction as the engaging force. The applied force first impacts the captured portion 370 such that the arms 372 release from retention features 342. This action separates the captured portion 370 from clamping portion 330. This same force also further compresses the resilient element 350 creating more potential energy. When said force is removed, the potential energy in 350 is converted to kinetic energy creating an opposing force large enough to push captured portion 370 away from clamping portion 330 during release.
In some other examples, captured portion 370 may be more than one component (not shown). In other examples, body 320 of captured portion 370 may have a shape forming a space between each of the arms 372. Said shape may add resiliency to these arms. Each arm 372 may have an aperture in some examples (not shown). These apertures may aid in resiliency and/or may be configured to receive thread or another type of retaining means to attach captured portion 370 to a substrate. Clamping portion 330 may also be shaped or contain apertures to receive thread or another material used for attachment to a substrate (not shown).
A cross-sectional view of 500 is displayed in FIG. 65 in the same engaged state as in FIG. 64. Shown here is a cross-section of one of the three arms 372 that comprise captured portion 370. The captured portion 370 may contain less or more than three arms (not shown). In some examples, each arm of 372 may be configured to deform when a force is applied to captured portion 370 to connect captured portion 370 with clamping portion 330. A cross-section of one of the three retaining features 342 is shown. There may be less, more, or a continuous annular retaining feature as part of 330.
As shown in FIG. 63, resilient spring element 350 may be attached to clamping portion 330 via some joining method such as, but not limited to, polymer dispersion (or emulsion) adhesives, reactive adhesives, hot melt adhesives, pressure-sensitive adhesives, adhesive epoxies, via an overmolding injection molding process, or some other joining method not listed here. FIG. 63 also shows button 305 attached to captured portion 370 via a snap fit interaction, although these two components may be connected via other joining methods.

In this embodiment, OHF system 500 is substantially similar to the one shown in FIGS. 63-65, with the same components and features so they will not be repeated again for sake of simplicity. In the exemplary embodiment shown in FIGS. 66-70, resilient spring element 350 is in a compressed state, with stored up energy.

The terminology used herein is for the purpose of describing particular examples only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, 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 may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. 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 examples.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In the discussion, terms “about,” “approximately,” “substantially,” and the like, when used in describing a numerical value, denote a variation of +/−10% of that value, unless specified otherwise.
The foregoing disclosure of the exemplary embodiments of the present subject disclosure has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the subject disclosure to the precise forms disclosed. Many variations and modifications of the embodiments described herein will be apparent to one of ordinary skill in the art in light of the above disclosure. The scope of the subject disclosure is to be defined only by the claims appended hereto, and by their equivalents.
Further, in describing representative embodiments of the present subject disclosure, the specification may have presented the method and/or process of the present subject disclosure as a particular sequence of steps. However, to the extent that the method or process does not rely on the particular order of steps set forth herein, the method or process should not be limited to the particular sequence of steps described. As one of ordinary skill in the art would appreciate, other sequences of steps may be possible. Therefore, the particular order of the steps set forth in the specification should not be construed as limitations on the claims. In addition, the claims directed to the method and/or process of the present subject disclosure should not be limited to the performance of their steps in the order written, and one skilled in the art can readily appreciate that the sequences may be varied and still remain within the spirit and scope of the present subject disclosure.
