Abstract

An apparatus for releasably attaching a temple to a lense frame. In one aspect, the inventive apparatus comprises: a grasping mechanism, at the forward end of the temple, for releasably, pivotably, and directly grasping a hinge pin provided on the lense frame, and a finger-operatable actuator for actuating the grasping mechanism to selectively release and pivotably grasp the hinge pin. When the grasping mechanism is secured to the hinge pin, the forward end of the temple will preferably be positioned directly adjacent to the lense frame such that the grasping structure is substantially hidden from outside view. Alternatively, the apparatus can comprise: an insert structure pivotably attached to the lense frame; a cavity provided in the forward end of the temple for receiving the insert structure; and a catch mechanism for releasably retaining the insert structure in the cavity. When the insert structure is retained in the cavity, the forward end of the temple will preferably be positioned directly adjacent to the lense frame such that the insert structure is substantially hidden from outside view.

Claims

1. An apparatus for releasably attaching a one-piece temple directly to a lense frame, said one-piece temple having a forward end and said lense frame having a hinge and hinge pin provided thereon, said apparatus comprising:

grasping means, at said forward end of said one-piece temple, for releasably, pivotably, and directly grasping said hinge pin such that said forward end of said one-piece temple is positioned directly adjacent to said lense frame and said grasping means is substantially hidden from outside view and

finger-operatable actuating means for actuating said grasping means to selectively release and pivotably grasp said hinge pin.

2. The apparatus of claim 1 wherein said grasping means comprises at least one jaw structure which opens when said grasping means is actuated by said finger-operatable actuating means.

3. The apparatus of claim 1 wherein said grasping means comprises a pair of jaw structures which open when said grasping means is actuated by said finger-operatable actuating means.

4. The apparatus of claim 1 further comprising biasing means for biasing said grasping means toward a closed position.

5. The apparatus of claim 1 wherein:

said finger-operatable actuating means comprises a slide bar which is moveable to a first position to open said grasping means and

said apparatus further comprises a biasing member which biases said slide bar to a second position to close said grasping means.

6. An apparatus for releasably attaching a temple to a lense frame, said temple having a forward end, said apparatus comprising:

a connector pivotably attached to said lense frame, said connector consisting essentially of a hinge and an insert structure extending from said hinge;

a cavity provided in said forward end of said temple for receiving said insert structure; and

holding means for releasably retaining said insert structure in said cavity,

wherein, when said insert structure is retained in said cavity and said apparatus is placed on a user'"'"'s head, said forward end of said temple is positioned directly adjacent said lense frame such that, as to said connector, no more than said hinge thereof will be visible from outside view.

7. The apparatus of claim 6 wherein said holding means is finger-operatable for releasing said insert structure from said cavity.

8. The apparatus of claim 6 wherein said insert structure includes a lip and said holding means comprises:

a slot provided in said temple, said lip being receivable in said slot when said insert structure is inserted into said cavity; and

biasing means, provided in said cavity, for releasably holding said lip in said slot.

9. The apparatus of claim 8 wherein said lip is removable from said slot by pressing said lip.

10. The apparatus of claim 6 wherein, when said insert structure is retained in said cavity, said cavity and said lip and said slot are hidden from outside view.
