DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

(11) Referring now to drawing FIGS. 1 and 2, and in accordance with various embodiments and aspects, the system and apparatus described herein overcomes the aforementioned difficulties in the prior art by providing a retention tether 10 for a pair of ear devices 1 that, when properly used, prevents accidental loss or dropping of ear devices 1 while remaining unobtrusive to a user. It should be noted that throughout the instant specification that the term ear devices should be construed synonymously with hearing aids, ear buds, audio devices, or any other relatively small object a user wishes to secure to their person without departing from the scope of the embodiments disclosed herein. As depicted in FIGS. 1 and 2 hearing aids 1 can include a battery compartment and amplifier for placement behind the ear, denoted generally by reference numeral 1, as well as a cone 2 that engages and covers the hearing aid speaker 3 prior to placement in the ear.

(12) In some exemplary aspects and embodiments retention tether 10 comprises is a flexible, predetermined length tether 20 having a first end 22 and a second end 24. Each end 22, 24 terminates in a loop 40 that is sized to accommodate ear devices 1. As best seen in FIG. 2 loop 40 is sized to accept hearing aid 3 with cone 2 removed, whereupon cone 2 is then placed over hearing aid 3 to prevent it from slipping back through loop 40. Flexible tether 20 may in some embodiments be constructed of a stretchable, flexible material, for example jewelry cord. In further embodiments clear or transparent jewelry cord such as elastic stretch cord can be utilized as material for tether 20 although a wide variety of flexible cord materials may be used as flexible tether 20 material. In some aspects flexible tether 20 is comprised of 1 mm diameter transparent jewelry cord in a variety of lengths to accommodate users of various sizes. Flexible tether 20 may in some exemplary embodiments have an overall length between loop 40 crimps 50 of 11-13.5 inches, although smaller or larger sized flexible tethers 20 may be utilized.

(13) In various embodiments loops 40 may be constructed by doubling first and second ends 22, 24 of flexible tether 20 and crimping them together utilizing a crimp 50, for example a jewelry crimp or similar plastic or metal crimp. Some embodiments may utilize silver jewelry crimps 50, for example silver crimps, having a weight of approximately 0.0635 grams each. Furthermore, loops 40 may be sized to accommodate various ear devices by moving the point at which ends 22, 24 are crimped. For example, loops 40 may comprise approximately 0.781 inches of flexible tether 20 material. However, a wide variety of loop 40 sizes may be employed in various embodiments without departing from the scope of the invention.

(14) In some exemplary aspects and embodiments retention tether 10 further includes a plurality of weights 60 disposed in a plurality of locations along flexible tether 20. A central weight 62 is fixed or secured at a point proximate a midpoint 26 of flexible tether 20, for example by affixing a crimp on tether 20 on either side of central weight 62. Of course central weight 62 can be secured to flexible tether 20 using a wide variety of methods and fasteners without departing from the scope of the various embodiments. In some embodiments weights 60 may include a central aperture 66 therein, such that flexible tether 20 is routed through weights 60.

(15) In accordance with other exemplary embodiments retention tether 10 includes a plurality of slidable weights 64 disposed along portions of flexible tether 20 by threading tether 20 through apertures 66. As depicted in FIGS. 1 and 3-8, at least one slidable weight 64 is positioned on either side of central weight 62. Slidable weights 64 a free to travel along flexible tether 20 from central weight 62 to loop 40 as the user moves, as will be discussed in detail below.

(16) In some exemplary embodiments weights 60 are beads having apertures 66 therein. In some embodiments weights 60 are comprised of natural materials such as stone, glass, wood, or metal, and may be decorative in nature, or clear and unobtrusive. In some embodiments weights 60 are generally spherical while in some others they may be generally cylindrical in shape. Spherical weights 60 are more readily movable against a users' neck since a very small surface area of a spherical weight will be in contact with a user's skin at any given moment. Weights 60 can be comprised of a wide variety of materials without departing from the scope of the embodiments detailed herein. Weights 60, 62, 64 may also be specifically selected and sized to be approximately 0.84 grams each to add the slight but necessary weight to retention tether 20 and thereby effectively secure ear devices 1 in place as the user moves. By providing weights 60 and crimps 50 having relatively light weights, the embodiments detailed herein provide enough force to hold ear devices 1 in place while retention tether 10 is worn, but not so much weight as to make tether 10 obtrusive or irritating over the course of a day's use.

(17) FIGS. 3-6 and 8 depict the movement and operation of retention tether 10 as a user moves naturally during the course of a day. Referring to FIG. 3, the user's head is essentially upright such that slidable weights 64 have traveled along retention tether 20 until they abut central weight 62. Thus the three weights 62, 64 exert a slight force along retention tether 20, which is of course connected to loops 40 and thus audio devices 1 in the user's ears. This slight force acts to hold devices 1 in the ears.

(18) FIG. 4 depicts the user leaning slightly to her right, wherein the right side slidable weight 64 has traveled to the lowest point in elevation along flexible tether 20, away from central weight 62, thereby providing weight to the right ear device 1, thus inhibiting its movement out of the ear. FIG. 5 depicts the same operation of retention tether 10 as the user leans to the left, whereby slidable weight 64 has traveled to the lowest point in elevation along flexible tether 20, away from central weight 62, thereby providing weight to the left ear device 1, thus inhibiting its movement out of the left ear.

(19) FIG. 7 depicts use of retention tether 10 with a pair of ear devices stored in a case or similar carrying apparatus. The small diameter of flexible tether 20 enables the user to store their ear devices in a carrying case without necessarily having to remove them from retention tether 10.

(20) As best seen in FIG. 8, where a user wants to remove their ear devices 1, retention tether 10 hangs easily about the neck and shoulders since slidable weights 64 travel down flexible tether 20 until they contact loops 40, thus gently weighting ear devices 1 and preventing them from falling to the ground or otherwise away from the users' body. Furthermore, when ear devices 1 are removed from the user entirely, retention tether 10 provides a simple way to store or hold the devices, since it can be looped over a door knob, bed post, or lamp finial or the like.

(21) In some aspects and embodiments as best depicted in FIG. 9, retention tether 10 may comprise a slidable grommet 10 that is used to form loops 40 in place of crimps 50. Slidable grommet 70 may be small enough in diameter to cinch end 22 to flexible tether 20 to form loop 40. By providing the ability to slide grommet 70 along flexible tether 20 back and forth in the direction of the arrow 5 a user can size loop 40 to fit a wide variety of ear devices 1. This embodiment enables the use of retention tether 10 with many different ear devices 1 such as hearing aids, ear buds, or even other devices worn over the ear such as glasses.

(22) While the present invention has been shown and described herein in what are considered to be the preferred embodiments thereof, illustrating the results and advantages over the prior art obtained through the present invention, the invention is not limited to those specific embodiments. Thus, the forms of the invention shown and described herein are to be taken as illustrative only and other embodiments may be selected without departing from the scope of the present invention, as set forth in the claims appended hereto.
