Detachable spectacle frame

Abstract

Detachable spectacle frame formed by a front, which in turn includes some rims, a bridge, some lugs and some nose pads; a pair of temples; in which each of the temples includes a hinge to engage the front, and a terminal end, where each of the rims and their corresponding temples has a defined slot. The removable frame being characterized in that each of the lugs further includes a laminar projection, finished by a hook; the hinge of each of the temples incorporates a recess and a kink and; further incorporates a fastening clip engaging the lug.

Claims

1. Detachable spectacle frame, comprising: a front, which in turn comprises: a plurality of rims for housing some lenses; a bridge for joining the rims together; a plurality of lugs having a laminar projection extending towards the inside of the front and finished with a protruding hook; and a plurality of nose pads to rest over the nose of an individual; and a pair of temples, wherein each one of the temples comprises: a hinge to engage the front, the hinge having a lateral recess defined at its end; and a terminal end to rest on the ear of the individual, wherein each of the rims and their corresponding lugs has a defined slot, the detachable frame comprising: the hinge of each one of the temples which comprises an integrated kink projecting from the inner face of the recess towards the inside of the temple, provided with a central slot and having at least one intermediate protrusion defined inside said central slot to engage the hook of the laminar projection; and it further comprises a fastening clip that engages the lug to be allocated in the recess, which it covers superficially, to secure the position of the slot and mechanically interacts with the kink to facilitate automatic folding and unfolding of the temples on the front.

2. Detachable spectacle frame according to claim 1, wherein the kink comprises a first section of essentially curved geometry, one end of which is projecting perpendicularly a second substantially straight section.

3. Detachable spectacle frame according to claim 2, wherein the intermediate protrusions in which the hook engages are located in the section of the central slot corresponding to the connection of the first section with the second section of the kink.

DETAILED DESCRIPTION

(7) A detailed explanation of a preferred embodiment of the object of the present invention is given below with the aid of the above-mentioned figures.

(8) The detachable spectacle frame described is formed by a front (1) and a pair of temples (2). The front (1) comprises in turn some rims (3) intended to receive some lenses (4), said rims (3) being connected to each other by a bridge (5), some lugs (6) defined on the rims (3) for attachment to the temples (2) and some nose pads (7) intended to rest on the nose of an individual, as shown in FIG. 1.

(9) Each of the temples (2) in turn comprises a front end or hinge (8) intended for engaging the front (1), and a rear or terminal end (9), intended to rest on the individual's ear, with an essentially curved geometry to facilitate said support over the ear and provided with a plastic coating to avoid friction and discomfort. A lateral recess (10) is further defined on the external face of the hinge (8), intended to face the outside of the frame, as shown in FIG. 2.

(10) On the other hand, each of the rims (3) and their corresponding lugs (6) has a defined dividing slot (11) to define an opening that allows the insertion of each of the lenses (4) in each of the rims (3) of the front (1), to form a spectacle.

(11) On the inner face of each of the lugs (6) a protrusion or laminar projection (12) is defined, which extends inwardly, as shown in FIGS. 2 to 4, being finished by a hook (13).

(12) On the other hand, from the inner face of the recess (10) defined in the hinge (8) of each of the temples (2) a kink (14) is projected towards the inside to be connected with the hook (13) of the front (1) to form the frame. The kink (14) has a defined central slot (15) within which intermediate protrusions (16) are defined. The kink (14) houses the laminar projection (12) once the engagement between each of the temples (2) and the front (1) has taken place, allowing rotation of the hinge (8) around the laminar projection (12) for opening and closing the temples (2) on the front (1), the hook (13) engaging the intermediate protrusions (16).

(13) A substantially parallelepiped and planar geometry clip (17) with fixing and embellishment functions of the frame engages the lug (6) and is located on the recess (10) of the hinge (8), as shown in FIG. 5. Said clip (17) firstly has the function of securing the position of the dividing slot (11), thus avoiding the disengagement of the lenses (4) inserted into the rims (3). On the other hand, as seen in FIGS. 3 to 5, when covering the recess (10) of the hinge (8), the clip creates a continuous surface from the beginning of the (6) to the terminal end (9) of the temple (2). In addition, being easily interchangeable, allows changing the exterior appearance of the frame.

(14) In the preferred embodiment described herein, the kink (14) comprises a first section (18) of essentially curved geometry, one end of which is projecting perpendicularly a second substantially straight section (19). The intermediate projections (16) in which the hook (13) engages are located in the section of the central slot (15) corresponding to the connection of the first section (18) with the second section (19) of the kink (14), as shown in FIG. 4.
