DETAILED DESCRIPTION

Reference is now made to FIGS. 1A, 1B, 2 and 3 illustrating one possible embodiment of the new and improved reversible earpiece 10. The reversible earpiece 10 includes a temple section or first body section 12 and a second body section 14. The second body section 14 includes an earpiece 16.

As illustrated, the first body section 12 and the second body section 14 are joined together by (a) a cooperating pivot 18 and receiver 20 and (b) a cooperating locking ball 22 and guide track 24. The pivot 18 is carried on either of the first body section 12 and the second body section 14 while the receiver 20 is carried on the other of the first body section and the second body section. Similarly, the locking ball 22 is carried on either of the first body section 12 and the second body section 14 while the guide track 24 is carried on the other of the first body section and the second body section.

In the embodiment illustrated in FIGS. 1A, 1B, 2 and 3, the pivot 18 and the locking ball 22 are carried on the second body section 14 while the receiver 20 and the guide track 24 are carried on the first body section 12. In other possible embodiments (not shown): (a) the pivot 18 and the guide track 24 are carried on the second body section 14 while the receiver 20 and the locking ball 22 are carried on the first body section, (b) the receiver 20 and the locking ball 22 are carried on the second body section 14 and the pivot 18 and guide track 24 are carried on the first body section 12 or (c) the receiver 20 and the guide track 24 are carried on the second body section 14 while the pivot 18 and the locking ball 22 are carried on the first body section 12. For purposes of this document, all four of these possible embodiments are contemplated and protected by the claims.

As best illustrated in FIG. 2, the guide track 24 includes a continuous channel 26 having a first end 28, a second end 30 and an inlet 32 provided between the first and the second ends. As illustrated in FIGS. 4A and 4B and described in greater detail below, the inlet 32 communicates with the continuous channel 26 and allows one to either insert the locking ball 22 into the continuous channel of the guide track 24 or remove the locking ball from the continuous channel of the guide track. Thus, one may quickly remove and/or change the second body section 14 and earpiece 16 as desired.

The locking ball 22 includes a bulbous head 34 supported on a neck 36. As should be appreciated, the bulbous head 34 has a greater cross sectional area than the narrower neck 36. The continuous channel 26 is shaped and adapted to receive the bulbous head 34. The first end 28 of the guide track 24 includes a first inlet slot 38 adapted to receive the neck 36 and prevent the passage of the bulbous head 34 from the continuous channel 26 while the second end 30 includes a second inlet slot 40 also adapted to receive the neck and prevent the passage of the bulbous head 34 from the continuous channel 26.

One joins the first body section 12 with the second body section 14 by aligning the pivot 18 with the receiver 20 and the locking ball 22 with the inlet 32 of the guide track 24. See FIGS. 4A and 4B. One then presses the two body sections 12, 14 together as illustrated by action arrows A of FIG. 4B. This forces the pivot 18 into the receiver 20 and the bulbous head 34 of the locking ball into the continuous channel 26 of the guide track. The beveled edge 19 of the pivot 18 aids in alignment and insertion of the pivot 18 into the receiver 20.

One then twists the second body section 14 with respect to the first body section 12 approximately 90 degrees in a first direction to capture the locking ball 22 in the first position at the first end 28 of the guide track 24 or approximately 90 degrees in a second direction to capture the locking ball in the second position at the second end of the guide track. When the locking ball 22 is in the first position, the earpiece 16 is in the first operative position illustrated in FIG. 4C and when the locking ball is in the second position, the earpiece is in the second operative position illustrated in FIG. 4D.

When one wants to remove or replace the second body section 14, one twists the second body section 14 with respect to the first body section 12 in order to align the locking ball 22 with the inlet 32 and then pulls the first and second body sections apart.

As should be appreciated, the guide track 24 extends through an arc of about 180 degrees centered on the pivot 18. Thus, in the first operative position, the earpiece 16 extends in a first direction (see FIG. 4C) with respect to the first body section 12 while in the second operative position, the earpiece extends in a second direction (see FIG. 4D) with respect to the first body section about 180 degrees opposite the first direction thereby making the earpiece reversible.

The inlet slots 38 and 40 at the first and second ends 28, 30 are wide enough to receive the neck 36 but are too narrow to allow the bulbous head 34 to pass through the slots. Thus, when the bulbous head 36 is at either of the first and second ends 28, 30, the two body sections 12 and 14 are secured together. A first detent 42 in the form of a cavity is provided in the wall 44 of the continuous channel 26 at the first end 28 to resist removal of the bulbous head 34 and capture and hold the locking ball 22 when the locking ball is in the first position. A second detent 46 in the form of a cavity is provided in the wall 44 of the continuous channel 26 at the second end 30 to resist removal of the bulbous head 34 and capture and hold the locking ball 22 when the locking ball is in the second position.

Reference is now made to FIGS. 6A-6D illustrating a head-mounted device 100 incorporating two of the reversible earpieces 10 illustrated in FIGS. 1A, 1B, 2, 3 and 4A-4D. As illustrated, the head-mounted device 100 includes an optical or other instrument 102 such as, but not necessarily limited to a camera C, an optical display or a monitoring device for communication with (a) a first intraocular device implanted within the first eye, (b) a second intraocular device implanted within the second eye or (c) a first intraocular device implanted within the first eye and a second intraocular device implanted within the second eye. In some embodiments, the head-mounted device 100 also includes a nose bridge 104. In the illustrated embodiment, the nose bridge 104 is two sided. In other embodiments, it may be reversible.

FIG. 6A-6D also illustrate how the head-mounted device 100 may be folded following use. As illustrated in FIG. 6A, the two earpieces 10 are folded outward with respect to the main body 106 of the device 100 when in use. The temple or first body sections 12 of the two reversible earpieces 10 are connected to the main body 106 by hinges H (FIG. 6A) received in the mount generally designated by reference numeral 108. This is consistent with state of the art eyeglasses construction.

Each reversible earpiece 10 is folded inward about the hinges as illustrated in FIGS. 6B and 6C so as to rest alongside the main body 106. The second body section 14 and earpiece 16 of one of the reversible earpieces 10 may then be twisted and reversed to point upward so that the earpiece 16 is fully contained within the upper and lower faces of the main body (see FIG. 6D).

FIGS. 5A-5I effectively illustrate a method of sequentially positioning the head-mounted device 100 in a first operative position with the instrument 102 in front of a first eye of an individual and a second operative position with the instrument in front of a second eye of the individual. That method generally includes the steps of: (a) orienting the reversible earpieces 10 connected to the head-mounted device 100 into a first position as illustrated in FIG. 5A; (b) positioning the head-mounted device into the first operative position in front of the first eye E1 (again see FIG. 5A and note action arrow B); (c) reorienting the reversible earpieces connected to the head-mounted device into a second position (see FIGS. 5F and 5G and note action arrows D and E); and (d) positioning the head-mounted device into a second position in front of the second eye (see FIG. 5H and note action arrow F).

More specifically, the method may also include the step of rotating the head-mounted device 100 and the reversible earpieces about a rotation axis AX extending between the reversible earpieces 10 and through the nose bridge 104 before positioning the head-mounted device into the second position (see FIG. 5E and note action arrow G). Further, the method may also include the step of removing the head-mounted device 100 from the first operative position before the reorienting of the reversible earpieces 10 connected to the head mounted device into the second position (see FIG. 5D and note action arrow H).

Still further, the method may also include the step of conducting a medical procedure, a therapeutic procedure or a monitoring procedure of the first eye with the instrument 102 of the head-mounted device 100 before the reorienting of the reversible earpieces 10 into the second position (see FIGS. 5B and 5C). Additionally, the method may include the step of conducting a therapeutic procedure, a diagnostic procedure or a monitoring procedure of the second eye with the instrument 102 of the head-mounted device 100 after the positioning of the head-mounted device into the second position in front of the second eye (see FIG. 5D).
