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.
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.
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.

The methods and apparatuses of the present invention have other features and advantages which will be apparent from or are set forth in more detail in the accompanying drawings, which are incorporated herein, and the following Detailed Description, which together serve to explain certain principles of the present invention.
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
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
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 web may include a peripheral tab 46 for mounting the tether to the harness. The web 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
The web 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.,
In various embodiments, the membrane or web is 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. As the web 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 web 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.com/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 web 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
The central opening may be elongated and asymmetric about a horizontal axis A, as shown in
In various embodiments, the area defined by the outer perimeter (e.g., P in
With reference to
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,
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
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
In various embodiments, tether apparatus 30a may be provided with overmolded connection to permanently attach tether 37a to harness 33a. In such embodiments, the harness may be molded in situ about the first end 51a of tether 37a, as shown in
In various embodiments, the solid region 47a is thicker than the remaining web 39a. In such embodiments, the solid region is up to twice as thick, or more, than the remaining web. 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 web, particularly if a logo 49a is formed in solid region 47a by sunken relief. One will appreciate that a web 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 60 may be formed between central opening 44a and corner apertures 40a. The ribs are also thicker than the remaining web 39a, 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 web. One will appreciate that a web with thickened ribs may also be formed by molding, casting, 3D printing, and/or other suitable means.
In various embodiments as shown in
Like the thickened solid region described above, tab 46b can be formed up to twice as thick or more as the remaining web 39b as shown in

As can be seen in
As shown in
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 33g 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.
