BACKGROUND OF INVENTION

Field of Invention

This application relates, in general, to a tether apparatus for handheld devices and methods for their use. This application also relates, in general, to a tether system for handheld devices and, more particularly, to a tether system for securing handheld devices to a user, as well as methods for their use.

Description of Related Art

The use of lightweight portable electronic devices such as mobile phones and tablets continues to increase. Users of modern personal electronic devices have come to rely on these devices for many functions. Aside from telephonic and electronic communication, photography is probably the most common use for such devices. In any event, such devices are generally within arm's reach of a user, if not carried within a pocket of the user.
Users carry these devices into various environments, including mountains, construction sites, rivers, lakes, oceans, amusement parks, war zones, search and rescue operations, and many more. Even if a user is carrying such a device within their pocket, the user must remove the device from their pocket to access the device's functionalities. And dropping a personal electronic device in these and other environments can result in several undesirable outcomes for a user. Firstly, the device could be damaged by the fall. Secondly the user could lose the device altogether, for example into water or deep snow. Thirdly the device could injure someone or cause damage to personal property if dropped from a significant height.
Also, users of modern personal electronic devices have come to rely on these devices for many functions. Aside from telephonic and electronic communication, photography is probably the most common use for such devices. Many of these devices are equipped with both front and rear facing cameras that allow the user to engage in a variety of photographic techniques, including snapshots, video journaling, and photographs of one's self (e.g., “selfies”). Because of the importance of the photographic functionality of these devices, it is important that any protective accessory be designed to limit the possibility of interfering with front and rear facing cameras integral to such devices. The challenge only becomes greater when one considers that various smartphone makes and models place their camera lens in different locations on their device.
Further, many users of personal electronic devices employ external cases to adorn, protect or otherwise augment their devices. The additional augmentation that cases can provide include external batteries, external memory storage, camera lenses, water protection, shock protection and more. Such external cases generally increase overall dimensions of the associated device and thus might affect or restrict the compatibility of certain accessories for the associated device.
Loom Some prior art devices have offered some degree of protection. Exemplars of the prior art include U.S. Pat. No. 9,438,299, which describes a stretchable strap cover for an electronic device, and U.S. Pat. No. 9,060,588, which describes a securement apparatus for a portable electronic device.
It would be useful, however, to provide apparatuses that assist users in securing their handheld devices to themselves, their clothing or other personal item, or to a pocket of their clothing or other personal item in a simple and convenient manner regardless of environment or circumstance, while maintaining access to as many as possible of the photographic functions of their handheld devices, regardless of whether the user employs an external case for their device, thereby overcoming the above and other disadvantages.

DETAILED DESCRIPTION

Reference will now be made in detail to various embodiments of the present invention(s), examples of which are illustrated in the accompanying drawings and described below. While the invention(s) will be described in conjunction with exemplary embodiments, it will be understood that present description is not intended to limit the invention(s) to those exemplary embodiments. On the contrary, the invention(s) is/are intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
Turning now to the drawings, wherein like components are designated by like reference numerals throughout the various figures, attention is directed first to FIG. 1 , which illustrates an exemplary a tether apparatus, generally designated 30, mounted on a handheld device 32 in the form of a mobile phone such as an iPhone 8 (trademark of Apple, Inc.) mobile phone that has a corner-mounted rear-facing camera as shown in FIG. 2 , and then to FIG. 6 , which illustrates the same tether apparatus 30 mounted on another handheld device 32′ in the form of a mobile phone having a centrally-mounted rear-facing camera such as an Android (trademark of Google, Inc.) mobile phone or a Galaxy 8 (trademark of Samsung Electronics Co., Ltd.) mobile phone as shown in FIG. 7 , in accordance with various aspects of the present invention.
Generally, tether apparatus 30 includes a harness 33, a fastener 35, and a tether 37 interconnecting the two. The harness is configured to stretch over and engage the respective corners of a handheld device, while the fastener is configured for releasably engaging an article attached to a user, such as clothing worn by the user or a personal item carried by the user. The tether interconnects the fastener and the harness whereby the tether prevents the handheld device from dropping far and allows a user to easily retrieve the handheld device if dropped while the fastener is engaged to the user's clothing or personal item.
In accordance with various aspects of the present invention, the tether apparatus of the present invention may be configured for use with various handheld devices that a user might carry on their person, including but not limited to personal or portable electronic devices such as smartphones and other mobile phones, tablets, e-readers, digital cameras, MP3 players, electronic toys, personal digital assistants, laptop computers and the like. In accordance with various aspects of the present invention, the harness is dimensioned and configured to releasably attach to various handheld devices, preferably being compatible with a wide variety of smartphones such that it allows a user unobstructed access and use of any front and/or rear facing cameras integral to the device.
With reference to FIG. 4 , harness 33 is generally formed of an elastomeric body, membrane or web 39. As can be seen in the various figures, and particularly in FIG. 9 and FIG. 38 , the elastomeric body includes a web layer of substantially uniform thickness W that extends throughout the elastomeric body. One will appreciate that the web layer may extend throughout the profile of elastomeric body. The elastomeric body includes a plurality of corner apertures 40 that each define a corner loop 42 configured to stretch over and engage a respective corner of the handheld device to releasably secure the harness to the handheld device. The elastomeric body further includes at least a central opening 44 that is configured to provide unobstructed access and use of centrally-located rear-facing cameras.
While the present invention has been described to allow unobstructed access to and use of cameras, one will appreciate that various handheld devices may have other hardware components that would likewise benefit from unobstructed access. For example, central opening 44 may allow unobstructed access to buttons, fingerprint scanners, flashes and other components that may be located on the rear side of a handheld device.
In various embodiments the elastomeric body may include a peripheral tab 46 for mounting the tether to the harness. The elastomeric body may also include a solid region 47 between the central opening and the tab that may strengthen the tab and also provide space for the provision of some indicia 49 such as a logo or other graphic, as shown in FIG. 4 . In various embodiments, the indicia may include an RFID chip that is implanted or otherwise located within the solid region.
The elastomeric body is formed of a polymer, preferably an elastomer that readily allows each corner loop to be stretched over a respective corner of the handheld device to thereby engage harness 33 to handheld device 32 (see, e.g., FIG. 1 ). The elastomeric body may be formed of silicone, rubber, neoprene, rubber, latex, urethane, and/or other suitable materials that provide the corner loops and overall elastomeric body with sufficient elasticity to stretch over and engage the corners of a handheld device. In various embodiments, the web is formed from an elastomeric sheet, in which the peripheral shape, corner apertures and central opening are cut from the sheet. One will appreciate that the web may be cut from an elastomeric sheet by stamping, laser cutting, waterjet cutting, or other suitable means. In other embodiments the web may be molded, cast, 3D printed, and/or manufactured by other suitable means.
In various embodiments, the web layer is of a substantially uniform thickness W in the range of 0.5 mm to 3.5 mm, preferably in the range of 1.0 to 3.0 mm, and more preferably in the range of 1.5 to 2.5 mm. As the web layer has a generally uniform thickness, the corner loops have a generally elongated rectangular cross-section, which shape is particularly well suited for engaging the corner of a handheld device. In contrast to a circular cross-section that may “roll off” the corner with relative ease, the rectangular and/or elongated cross-section in combination with the tension of corner loop 42 while stretched over a corner of the handheld device will reduce the possibility of the corner loop from rolling of the edges of the handheld device.
In addition, the elastomeric body is dimensioned and configured to have sufficient stretch or flexibility to allow each corner loop be stretched over a respective corner of the handheld device regardless of whether or not a close-fitting external case is mounted on the device. For example, Apple, Inc., the manufacturer of iPhone mobile phones, offers silicone, leather, wood, and other cases that largely surround the sides and back of respective mobile phones (see, e.g., https://www.apple.conn/shop/iphone/iphone-accessories/cases-protection). While some cases are generally close fitting, and other cases bulkier, such cases generally add to overall height, width and thickness. Accordingly, the elastomeric body is preferably dimensioned and configured to have sufficient stretch or flexibility to allow each corner loop be stretched, not only over a respective corner of a mobile phone, but also over the respective corner of a case mounted to the mobile phone.
Many handheld devices are generally rectilinear. Accordingly, harness 33 includes four corner apertures and corner loops, with each loop being configured to stretch over and engage a respective corner of the rectilinear device. One will appreciate that other handheld devices may have other shapes, with three, four or more corners. Accordingly, one will appreciate that the harness may have other geometric shapes with a number of corners that correspond to the respective handheld devices. One will also appreciate that the harness need not have a corner aperture and corner loop that corresponds with all of the corners of a respective device. For example, in the case of a rectangular smartphone, one will appreciate that a triangular harness might be configured to have three corner apertures and loops that are configured to stretch over and engage three of the four corners of the smartphone to provide engagement of the triangular harness to a rectangular smartphone.
As noted above, central opening 44 is configured to provide unobstructed access and use of centrally-located rear-facing cameras. In various embodiments, the central opening is located at the centroid C of the web, as shown in FIG. 4 . As the elastomeric body is monolithically formed, the web layer generally has a substantially uniform material density, and thus the centroid of the web layer is generally concentric with the center of gravity of the web layer. In various embodiments, the central opening may be formed such that it has a maximum opening dimension (e.g., Dmo) larger than the maximum aperture dimension (e.g., Dma) of any of the corner apertures 40, as shown in FIG. 4 , which configuration allows unobstructed access and use of centrally-located rear-facing cameras. As can be seen in FIG. 4 , the maximum opening dimension Dmo extends along a longitudinal axis of the elastomeric body, and the maximum aperture dimension Dma is substantially parallel to the longitudinal axis of the elastomeric body.
The central opening may be elongated and asymmetric about a horizontal axis A, as shown in FIG. 4 , which configuration is also particularly suited for use with mobile phones have a centrally-located rear-facing camera of the type shown in FIG. 7 . One will appreciate, however, that the shape of the central opening may vary. For example, the central opening may be egg-shaped, circular, oval, oblong, or of other suitable shapes. In various embodiments, the perimeter of the central opening is free of sharp corners so as to avoid stress points at which the elastomeric body might tear.
In various embodiments, the area defined by the outer perimeter (e.g., P in FIG. 4 ) of the elastomeric body would be of similar proportions but smaller than the area defined by the general shape of the handheld device. Similarly, the overall height and width dimensions of the elastomeric body, not including the tab, would be smaller than the overall height and width dimensions of the handheld device. Preferably, the overall height and width dimensions of the elastomeric body are at least approximately 10% smaller than those of the handheld device, preferably at least approximately 15% smaller, and more preferably at least approximately 20% smaller. For example, in the case of a personal electronic device having generally rectangular shape with a height of 138 mm and a width of 67 mm (e.g., an iPhone 8 mobile phone), an elastomeric body having a height of 110 mm and a width of 54 mm would be particularly well suited to allow the corner loops to stretch over and engage the respective corners of the personal electronic device. One will also appreciate that the same elastomeric body may be used to engage other similarly sized phones but having a slightly larger height, for example one having a height of 149 mm and a width of 68 mm (e.g., a Galaxy S8 mobile phone). And if the personal electronic device has an external case mounted thereon, such dimensions of the elastomeric body are also suitable to allow the corner loops of the elastomeric body be stretched over and engage the corners of both the personal electronic device and its external case mounted thereon.
With reference to FIG. 4 , tab 46 extends downwardly from elastomeric body 39 generally between the lower two corner apertures 40. In various embodiments, the tab includes a hole designed to receive an end of tether 37. In other embodiments, the elastomeric body may be monolithically formed with and/or integrally attached to the tether. For example, the tether may be molded with the web and harness of the same material and of unitary construction, such as that shown in FIG. 20A. Alternatively, the tab and/or harness may be overmolded around the tether to form a strong permanent connection between the tab and tether, as shown in FIG. 9 . As also shown in FIG. 9 , thickened solid region 47 has a thickened solid region layer of thickness S that overlaps a portion of the web layer thickness W to increase the structural integrity of the elastomeric body adjacent to the tether. As can be seen in FIG. 9 , thickened solid region 47 a has an overall thickness substantially equal to the combined thickness of the web layer and the thickened solid region layer (e.g., W+S). As shown in FIG. 8 , thickened solid region 47 a (and its thickened solid region layer thickness) may be provided between an adjacent pair of the four corner apertures (i.e., the pair of corner apertures closest to first end 51 a of tether 37 a), as well as between central opening 44 a and elongated tether 37 a.
Tether 37 includes a first end 51 connected to tab 46 and a second end 53 connected to fastener 35. In various embodiments, the tether is retractable with first and second ends in the form of closed loops that are closed. The loops may be mechanically formed (e.g., by a crimp 54, by stamping, etc.), however, the loops may be formed by other means such as monolithically formed with the tether, thermally formed (e.g., folding an end back and heat welding the end to the tether), or chemically formed (e.g., folding an end back and chemically bonding the end to the tether), or formed by other suitable means. One will appreciate that the tether may take various forms, for example the tether may be formed of a strap made of plastic, nylon, urethane, leather, metal, urethane, or other suitable material. Alternatively, the tether may be formed of rope, paracord, cordage, chain, or other suitable means. The tether may be flat, round, coiled, or of other suitable shapes. Further still, the tether may be a retractable, for example, a retractable lanyard, coiled, elastic, and/or otherwise configured to retract. The closed ends may similarly take various forms, for example, molded loops, rings, hooks, crimps, and ring terminals may be utilized. The tether ends may also be bonded against itself to form closed loops, for example, nylon cord ends may be welded against the nylon cord to form a welded loop in an otherwise conventional fashion. Regardless of the form, the tether is configured to securely interconnect fastener 35 to harness 33 in order to allow a user to securely attach their handheld device to their person.
In various embodiments, tether 37 has a maximum length when fully extended of approximately 4 feet. One will appreciate that such a length will prevent a handheld device from impacting the ground when the handheld device is secured to a user's clothing or personal item (or to a user's pocket as discussed below), particularly when the user is elevated, for example, while the user is rock climbing, seated on a chair lift, hang gliding, boating, or participating in other activities where the handheld device might be inadvertently dropped, for example, while the user is hiking, biking, skiing, or otherwise moving. Moreover, even if the tethered handheld device is not dropped from a significant height, it will be readily retrievable by the user by simply “pulling the line”, that is, simply retrieving the tethered handheld device by pulling the tether toward themselves. Accordingly, if the handheld device is inadvertently dropped into water, soft snow, or other soft surface into which the handheld device could sink, the user may readily retrieve the handheld device by simply pulling the tether toward themselves.
In various embodiments, fastener 35 is a clip having a jaw 56 movably mounted on a base 58. The base and the jaw are pivotally coupled about an axis in such a way that the jaw can pivot to open and close the clamp. When the clip is in its open position there is room between the base and the jaw to insert a small part of a user's clothing or other personal item, such as a backpack, purse, handbag, duffle, hiking sticks, or other items carried by a user. The base and the jaw may have raised ridges designed to meet and securely pinch therebetween the user's clothing or item. For example, FIG. 1 shows clip 35 in its closed position pinching the fabric of a user's clothing or other item. The base also has a mounting hole through which second end 53 of tether 37 may be attached. One will appreciate that other types of fasteners may be used, for example, clasps, buckles, carabiners, S-clips, cable rings, girth hitches, or other attachments that may be used to releasably engage articles of clothing such as coats, shirts, pants, belts, belt loops, etc., or other personal items.
In operation and use, tether apparatus 30 provides a simple and secure way for a user to connect a handheld device to their clothing or other personal items while maintaining access to all the photographic and other functions of that device, with or without a case.
To use tether apparatus 30, a user would in no particular order perform the following actions: place the central aperture 44 at the rear of their handheld device and then stretch the four corner apertures 40 and corresponding corner loops 42 over the edges of their electronic device so that furthest extended portion of the corner loops wrap around to the front side of the handheld device, as shown in FIG. 1 ; and using clip 35, attach tether 37 to an item of the user's choosing such as an article of clothing or a backpack.
An exemplary use of tether apparatus 30 is a skier riding a chairlift who wants to place a call, check email, or take several photographs with their smartphone. In this example, the skier is on a chairlift elevated above the surface of the snow such that if they were to drop their smartphone, it would likely be altogether lost to them. And the skier may be using a battery case, encasing their smartphone to extend the life of the smartphone battery. Using the tether apparatus, the skier would be able to remove their smartphone (along with the battery case if used) from their jacket pocket without having to worry about damaging the smartphone, losing the smartphone altogether, and/or causing harm to another person or personal property located below the chair lift. When the skier removes the smartphone from their jacket pocket, the skier would be able to both take photographs using either the front or rear facing camera lenses. In addition, the skier would be able to enjoy full use of the smartphone as well as the protection and extended battery life offered by the protective case while keeping their smartphone secured to their person. And if the skier were to inadvertently drop the smartphone, it could only drop the length of the tether, thus avoiding loss or injury below. To retrieve the smartphone, the skier need only pull on the tether and grab the smartphone.
In various embodiments as shown in FIG. 8 , tether apparatus 30 a is similar to that described above but includes an overmolded connection 59, a thickened solid region 47 a, thickened reinforcing ribs or thickened reinforcement 60, and an alternative fastener 35 a in the form of a carabiner style clip.
In various embodiments, tether apparatus 30 a may be provided with overmolded connection to permanently attach tether 37 a to harness 33 a. In such embodiments, the harness may be molded in situ about the first end 51 a of tether 37 a, as shown in FIG. 9 . One will appreciate that such overmolding may facilitate manufacturing by reducing part count and simplifying assembly.
In various embodiments, the solid region 47 a is thicker than the remainder of elastomeric body 39 a, and thicker than thickness W of the web layer. In such embodiments, the solid region may have a thickness S that is up to twice as thick, or more, than the web layer thickness Was well as the remainder of the elastomeric body. For example, the solid region may be about 6 mm, 8 mm, 10 mm thick or more. The additional thickness may provide additional structural integrity to the elastomeric body, particularly if a logo 49 a is formed in solid region 47 a by sunken relief. One will appreciate that an elastomeric body with a thicker solid region may be formed by molding, casting, 3D printing, and/or other suitable means.
In various embodiments, one or more ribs or reinforcements 60 may be formed between central opening 44 a and corner apertures 40 a. As shown in FIG. 9 , the ribs have a reinforcement layer of thickness R that overlaps a portion of the web layer and extends along and adjacent to at least a pair of the four corner apertures 40 a. The ribs are also thicker than the remainder of elastomeric body 39 a (not including the thickened solid region), and may be up to twice as thick, or more. Like the thicker solid region above, thicker ribs may also provide additional structural integrity to the elastomeric body. One will appreciate that an elastomeric body with thickened ribs may also be formed by molding, casting, 3D printing, and/or other suitable means.
In various embodiments as shown in FIG. 10 , tether apparatus 30 b is similar to those described above but includes a thickened tab 46 b, and an alternative tether 37 b in the form of retractable lanyard.
Like the thickened solid region described above, tab 46 b can be formed up to twice as thick or more as the remainder of the elastomeric body 39 b as shown in FIG. 11 , or even thicker. Again, the additional thickness may provide additional structural integrity to the elastomeric body, and particularly the tab to which the tether is attached.
In various embodiments as shown in FIG. 12 , tether apparatus 30 c is similar to those described above but includes an alternative harness 33 c, and an alternative tether 37 c in the form of metal chain.
As noted above, the harness and central opening may take various shapes. Similarly, the corner apertures, corner loops, and tab may take various shapes. In various embodiments, corner apertures 40 c and corner loops 42 c may have a more pointed configuration, the central opening may be wider, and/or the tab 46 c may have linear edges.
In various embodiments as shown in FIG. 13 , tether apparatus 30 d is similar to those described above but includes an alternative harness 33 d, and an alternative tether 37 d in the form of a cord. As noted above, the elastomeric body is provided with at least one central opening. In various embodiments, the elastomeric body 39 d may be provided with multiple central openings 44 d, 44 d′, at least one of which is large enough to provide unobstructed access to and use of a rear-facing camera as discussed above.
In various embodiments as shown in FIG. 14 , tether apparatus 30 e is similar to those described above but includes an alternative harness 33 e and an alternative tether 37 e in the form of a roller chain. In various embodiments, and similar to elastomeric body 39 d above, elastomeric body 39 e may be provided with multiple central openings 44 e, 44 e′, 44 e″.
In various embodiments as shown in FIG. 15 , tether apparatus 30 f is similar to that described above but includes an alternative harness 33 f, and an alternative tether 37 f in the form of plastic chain. In various embodiments, central opening 44 f may be further enlarged and may be symmetric about a horizontal axis.
Turning now to FIG. 16 and FIG. 17 , and as noted above, the elastomeric body is dimensioned and configured to have sufficient stretch or flexibility to allow each corner loop be stretched over a respective corner of the handheld device regardless of whether or not an external case is mounted on the device. As shown in FIG. 16 and FIG. 17 , harness 33 is mounted on both handheld device 32′ and its external case 63.
Turning now to FIG. 18 and FIG. 19A, in various embodiments, tether apparatus 30 g is similar to that described above but includes an alternative harness 33 g and a retractable tether assembly 65 including a retractor housing 67 having a rewind button 68 that is mounted within the harness.
Retractable tether assembly 65 generally includes a spring-loaded spooling mechanism housed within retractor housing 67 that permits tether 37 g to be unwound by pulling on the tether, which spooling mechanism automatically locks the unwound tether against retraction onto the spool device, and retracts the tether upon pressing rewind button 68 (see FIG. 18 ). Such spooling mechanisms are otherwise conventional, functionally similar to widely known badge reels, retractable lifelines, and other known self-winding devices. For example, such spooling mechanisms are functionally similar to that shown in U.S. Pat. No. 1,120,341 to Smith.
As can be seen in FIG. 19A, retractor housing 67 is located within elastomeric harness 33 g. The elastomeric harness includes a chamber 70 in which the retractor housing is located, whereby the elastomeric harness encases the retractor housing. The elastomeric harness may also include a tether passage 72 extending downwardly from the chamber to provide access for elongated tether 37 g to retract through the elastomeric harness and into the retractor housing. Like the above tether apparatuses, a fastener 35 g is connected to a terminal end 53 g of the elongated tether 37 g, and is configured for releasably engaging an article attached to a user thus allowing the user to easily retrieve the handheld device if dropped.
As shown in FIG. 19A and FIG. 19B, retractable tether assembly 65 may include a tube 74 through which elongated tether 37 g extends out from retractor housing 67. The tube may be provided to minimize and/or prevent frictional rubbing between the elongated tether and the inner surface of tether passage 72 of elastomeric harness 33 g. The tube may be discrete from the retractor housing, as shown in FIG. 19A and FIG. 19B. One will appreciate, however, that retractor housing 67 h and tube 74 h may be integrally connected and/or monolithically formed, as shown in FIG. 20A and FIG. 20B.
Like the harnesses described above, elastomeric harness 33g may be formed of various materials suitable for molding, casting, 3D printing, and/or other like means to form the harness about the retractor housing. For example, harness 33 g may be formed in situ about the retractor housing 67 such that the retractor housing defines chamber 70 within the formed harness. Forming the harness in situ about the retractor housing creates a monolithic elastomeric harness. As such, the retractor housing may be permanently mounted within the chamber of the elastomeric harness, wherein the only way to remove the retractor housing from the harness is by tearing or otherwise damaging the harness.
One will appreciate that integrally and/or monolithically forming tube 74 with retractor housing 67 may simplify construction, not only by reducing part count, but also by simplifying in situ forming. For example, if the tube and retractor are integral with one another, only one item need be indexed or oriented within a mold cavity during in situ molding.
One will also appreciate that such in situ forming around the retractor housing is well suited for forming elastomeric bodies configured for releasably engaging various handheld devices that a user might carry on their person. One will further appreciate that such elastomeric bodies may include the harnesses, webs and membranes described above, but may also include other elastomeric bodies that are configured to releasably engage smartphones, tablets, and the like.
Turning now to FIG. 20 , in various embodiments, tether apparatus 30 i is similar to that described above but includes a monolithic harness 33 i and tether 37 i. Namely, the harness and the tether are monolithically formed of a single piece of material. Like the harnesses described above, the monolithic harness and tether may be formed of various materials that are suitable for molding, casting, 3D printing, and/or other like means.
Like the harnesses described above, tether 37 i may similarly be flat. For example, the tether may be of substantially uniform thickness in the range of 0.5 mm to 3.5 mm, preferably in the range of 1.0 to 3.0 mm, and more preferably in the range of 1.5 to 2.5 mm. Alternatively, as shown in FIG. 22A and FIG. 22B, the tether may have protrusions 75 in the form of nubs, ribs or other structure projecting from the uniform thickness in order to vary the overall coefficient of elasticity of the tether.
A first end of 51 i of tether 37 i is integrally connected to elastomeric body 39 i, and a second end 53 i of the tether is releasably connected to fastener 35 i. In various embodiments, the second end may be formed with a loop 77 that may be used to secure the second end to the fastener with a girth hitch 79 in an otherwise conventional manner. One will appreciate that the material of the tether and the dimensions of the second end loop should be configured to allow the second end loop to stretch sufficiently to allow the harness to pass through the loop.
In various embodiments, tether 37 i is retractable having a first retracted length in its relaxed condition, as shown in FIG. 20A, and a second extended length in its pulled condition. For example, the tether may be formed of an elastic material in which a user and/or the weight of the handheld device, may pull second end 53 i away from first end 51 i (or vice versa) thereby stretching the tether to its extended length, and the elastic memory of the material tends to bias the tether back to its retracted length. In various embodiments, the tether includes a series of interconnected bends 81. One will appreciate that, when second end 53 i is pulled away from first end 51 i (or vice versa), the series of bends may flex and straighten and thus allow the tether to lengthen.
In various embodiments, as shown in FIG. 21B, fastener 35j may include a hanger 82 configured to receive a portion of harness 33 j such that the harness can be hung from the fastener while the fastener is clamped to an article worn or borne by the user, or while clamped to other article such as a tent seam, etc. Such a hanger provides for a convenient storage position when the harness is not attached to an electronic device. With reference to FIG. 21C, the hanger includes a hook or slot extending from clip jaw 56 j approximating the thickness of the elastomeric body to readily receive a portion of the elastomeric body.
Turning now to FIG. 23 , an exemplary tether system, generally designated 130, is mounted on a handheld device 132 and secured within a pocket 133. The tether system of the present invention is also particularly suitable for use with the mobile phones, smartphones, and other devices described above.
Generally, and with reference to FIG. 25 , tether system 130 includes a harness 135, a pocket 133 provided on an article worn or borne by a user (e.g., jacket 137 in FIG. 23 , backpack 137 a in FIG. 26 , etc.), and a tether 139 releasably securing the harness to the pocket. The harness is configured to stretch over and releasably engage the respective corners of a handheld device, while the tether is configured for releasably engaging a mount 140 secured within the pocket. The tether interconnects the harness and the mount within the pocket, whereby the tether prevents the handheld device from dropping far and allows a user to easily retrieve the handheld device if dropped. Like the harnesses described above, harness 135 is generally formed of an elastomeric body, membrane or web (see, e.g., elastomeric body 142 d in FIG. 30 ) including a plurality of corner apertures (see, e.g., apertures 144 d in FIG. 30 ) that each define a corner loop 146 configured to stretch over and engage a respective corner of the handheld device to releasably secure the harness to the handheld device. And like the harnesses described above, harness 135 may include a tab 147, a solid region and/or indicia located between the lower corner loops (see, e.g., solid region 149 d and indicia 151 d in FIG. 30 ).
Tether 139 includes a first end 153 connected to harness 135 and a second end 154 releasably connected to mount 140. In various embodiments, the tether is a coiled nylon cord having first and second ends in the form of closed loops that are closed by a crimp 156, however, one will appreciate that the various tethers described above may be utilized. Preferably, the tether is retractable to some degree such that it is self-retracting as a user places the handheld device in their pocket. For example, the coiled tether 139 shown in FIG. 25 is self-coiling to reduce the overall length of the tether as the handheld device is placed in the user's pocket, thus avoiding unnecessary tangling of the tether. Similarly, the elastic-cord tether 139 c shown in FIG. 28 , and the monolithic tether 139 g shown in FIG. 29 , will return to their unstretched lengths as the handheld device is placed in the user's pocket. One will appreciate that various other retractable tethers may be utilized in accordance with various aspects of the present invention.
Regardless of the form, the tether is configured to securely interconnect the harness to the mount located within the pocket, thus allowing a user to securely and releasably interconnect the tether system to both their handheld device to their pocket in a manner that allows the user to conveniently secure the handheld device within their pocket while providing the user with ready, yet secured access to the handheld device.
In accordance with various aspects of the present invention, tether 139 includes a fastener 158 to releasably secure second end 154 of tether 139 to mount 140 within pocket 133. In various embodiments, and as shown in FIG. 25 , the fastener may be a clip or carabiner having a body 160 and a gate 161. The body and the gate are pivotally coupled in such a way that a user may simply slip the fastener around the mount such that the mount enters the clip through the gate and thus clip the fastener to the mount. One will appreciate that other types of fasteners may be used, for example, clasps, buckles, carabiners, S-clips, cable rings, girth hitches (see, e.g., girth hitch 158 g in FIG. 29 ) or other attachment devices that may be used to releasably engage the tether to the mount within the user's pocket. For example, the fastener may be in the form of a crimped loop at the second end 154 of tether 139, as shown in FIG. 25 , or in the form of a buckle 163 c as shown in FIG. 28 . Such buckles have separable first and second parts, in which the first part is secured to the second end tether 139 c, and the second part is secured to mount 140.
As noted above, the pocket-bearing article 137, 137 a may be worn or born by a user. In particular, the article may be an article of clothing worn by the user, such as the jacket 137 shown in FIG. 23 , or the article may be a personal item 137 a carried by the user such as the backpack shown in FIG. 26 . One will appreciate that various articles of clothing may be used including, but not limited to, jackets, vests, shirts, pants, shorts, and other suitable articles of clothing worn by a user. Similarly, one will appreciate that various personal items may be used including, but not limited to backpacks, courier bags, handbags, purses, childcare bags, work bags, briefcases, and other personal items carried by the pocket.
In various embodiments, the pocket may be open. And in various other embodiments, the pocket may be enclosed with zippers, hook fasteners such as Velcro®, snaps, buttons, buckles, magnets, and other suitable means. For example, as shown in FIG. 25 , pocket 133 may have a zipper 165 that is selectively opened to allow access to the handheld device 132. Alternatively, as shown in FIG. 26 , pocket 133 a may have a flap 167 that may be selectively opened. One will further appreciate that other pocket configurations may be utilized in accordance with various aspects of the present invention to allow a user ready access to a handheld device stored within.
In the illustrated embodiment of FIG. 25 , mount 140 may be a loop having two ends secured to the article 137, within pocket 133. One will appreciate that other mounts may be utilized in accordance with the present invention. For example, a tab may be used to which the fastener may be releasably secured. One will appreciate that other types of mounts may be utilized in accordance with the present invention to provide a suitable anchor within the pocket to which the second end of the tether may be releasable secured.
As also shown in FIG. 25 , mount 140 may be secured within pocket 133 along a perimeter (e.g., a seam) remote from the opening. For example, mount 140 may be secured at a corner 168 that is remote from the opening. In various embodiments, the mount is positioned a distance from the opening that is substantially equal to or greater than the overall length of the handheld device. Such configuration may facilitate placement of the handheld device into the pocket as the retractable nature of the tether may reduce or prevent tangles of the tether while the handheld device is placed into the pocket.
In various embodiments, the solid region of the elastomeric body may be modified to receive removable indicia. For example, solid region 149 d may be provided with a recessed receptacle 170 into which an object such as a medallion 172 is received, as shown in FIG. 30 and FIG. 31 . Such medallions allow customization of the tether system to promote branding and/or other ornamentation. Alternatively, the receptacle may be configured to receive one or more accessories. For example, an LED light, a grip, a stand, tripod, clamp, RFID chip and/or other accessories may be releasably engaged to the harness via the receptacle. For example, an RFID chip 173 may be mounted within the receptacle within, on or below the medallion 172, as shown in FIG. 30 and FIG. 31 .
One will appreciate that the solid region may be monolithically formed with the remainder of the elastomeric body, or may be formed of a second material, such as a stiffer silicone, rubber, neoprene, rubber, latex, urethane, etc., or a more rigid material such as plastic, composite, metal, and/or other suitable material. When a second material is utilized, the elastomeric body may be 3D printed with two different materials, or the elastomeric body remainder may be cast about the solid region, overmolded about the solid region, affixed to the solid region by a suitable adhesive or bonding agent, or by other means.
One will appreciate that medallion 172 may be permanently attached to solid region 149 d by glue or other suitable means. Alternatively, the medallion may be releasably attached to the solid region. For example, the medallion may be snapped into receptacle 170 in an otherwise conventional fashion.
Alternatively, the medallion may have an insert-and-twist configuration, as shown in FIG. 32 and FIG. 33 . For example, receptacle 170 e may be provided with one or more lobes 174, and medallion 172 e may have recessed areas that allow the medallion to be inserted into the receptacle past the lobes, and then twisted to engage the lobes to releasably lock the medallion in the receptacle. Such an insert-and-twist configuration may be particularly suited to receive a clamp accessory that may be attached to a ski pole or hiking stick to form a selfie stick.
And further still, the medallion may have a slide-in configuration, as shown in FIG. 34 and FIG. 35 . For example, receptacle 170 f may be provided with a shoulder 175 partially extending around the receptacle. The medallion may slide in through the open side of the receptacle and under the shoulder such that the medallion is releasably engaged within the receptacle. One will appreciate that other receptacle and medallion configurations may be utilized to affix indicia and other ornamentation to the thickened region. Also, such a slide-in configuration may be particularly suited to receive a clamp accessory that may be attached to a ski pole or hiking stick to form a selfie stick.
With reference to FIG. 23 and FIG. 26 , in operation and use, tether system 130 provides a simple and secure way for a user to connect a handheld device to their clothing or other personal items while maintaining access to all the photographic functions of that device with or without a case. Tether system 130 is used in a manner similar to the tether apparatuses described above, with the primary difference being the second end 154 of tether 139 is secured to mount 140 within pocket 133 of the user's article (see, e.g., FIG. 25 ), such as an article of clothing 137 (e.g., FIG. 23 ) or a personal item 137 a (e.g., FIG. 26 ).
In various embodiments, as shown in FIG. 36 to FIG. 38 , elastomeric body 39 m and elongated tether 37 m may be monolithically formed, with the tether being significantly longer than the elastomeric body. As shown in FIG. 4 above, the elongated body may have a height H parallel to a longitudinal axis L of the elastomeric body, and the length of the tether may be significantly longer than the height H of the elastomeric body. As shown in FIG. 36 , the elongated tether may be at least twice as long as the height H of the elastomeric body. Such length may provide enough slack for the user to comfortably use a secured handheld device, but not so long as to allow the secured handheld device to hit the ground if inadvertently dropped by the user. With reference to FIG. 37 and FIG. 38 , the tether may be substantially flat having a substantially uniform thickness between the first end 51 m and second end 53 m that is equal to thickness W of the web layer.
Elastomeric body 39 m preferably includes a web layer of substantially uniform thickness W throughout its overall profile to form a solid and mostly uninterrupted base layer. One will appreciate that branding and other indicia may be provided by sunken relief in the web layer, the solid region layer, and/or the reinforcement layer. In various embodiments, elastomeric body has a thickened solid region layer of thickness S that overlaps a portion of the web layer thickness W to increase the structural integrity of the elastomeric body adjacent to the tether, as is shown in FIG. 9 . The thickened solid region layer may extend between an adjacent pair of the four corner apertures, and between central opening 44 m and elongated tether 37 m. As shown in FIG. 38 , thickened solid region has a resulting thickness of W+S adjacent the first end of the tether, which thickened solid region may significantly strengthen the elastomeric body and prevent failure where the elongated tether connects to the elastomeric body.
Like the embodiment shown in FIG. 4 , elongated body 39m includes a central opening 44 m having a maximum opening dimension Dnno (along a longitudinal axis L) that is larger than the maximum aperture dimension Dma (parallel to the longitudinal axis L) of the four corner apertures 40 m. The configuration of such a larger central opening provides unobstructed access to a centrally mounted rear-facing camera while the harness is engaged to a handheld device. In addition, one will appreciate that such a larger central opening may also provide unobstructed access to the central portion of the rear surface of the handheld device, thus allowing various accessories to be used while the handheld device is secured to the harness.
Like the embodiments shown in FIG. 8 and FIG. 18 , elastomeric body 39 m may be provided with one or more reinforcements 60 m. In particular, the reinforcements may include a reinforcement layer of thickness R that overlaps a portion of the web layer thickness W to provide a reinforced area that provides additional structural integrity to the elastomeric body. Like the above embodiments, reinforcements 60 m extend along and adjacent to at least a pair of the four corner apertures. In various embodiments, a reinforcement 60 m may continuously extend along and around a pair of corner apertures 40 m. And in various embodiments, a reinforcement layer 60 m′ may extend along a portion of the thickened solid region 47 m and around a pair of the corner apertures 40 m′.
In many respects, various modified features of the various figures resemble those of preceding features and the same reference numerals followed by subscripts “a”, “b”, “c”, “d”, “e”, “f”, “g”, “h”, “i”, “j”, “k”, “l” and “m” designate corresponding parts.
