Description

Assembly glasses with screwless eyeglass hinges

The present invention is a screwless spectacle hinge capable of assembling spectacles without screwing by configuring a spectacle hinge to support the rim of the lens by bending a wire of a thin wire to support the rim of the lens and to prevent the connecting members intersecting with each other in the horizontal and vertical directions from being inserted and removed. It relates to a prefabricated glasses having.

Glasses are optical devices that are used habitually for correcting the user's eyesight, protecting the eyes from strong ultraviolet rays, wind, and dust, or for fashion accessories. The general configuration of glasses includes a pair of rims, which are a pair of frames to which lenses are combined, a bridge that connects the rims to each other, a temple that is hinged to both sides of the rim to hang on the ears, and a nose ring. Include.

These conventional rims and temples are fastened with screws to hinges respectively formed on both sides to be freely folded or unfolded. In order to assemble and disassemble them, a separate tool such as a driver is required, so it takes a lot of time to assemble the glasses. In addition, since the hinge member is connected to the end of the temple and the rim by welding, the configuration is complicated, glasses manufacturing is cumbersome, and a skilled technician who can join by argon welding is required, and welding is difficult, resulting in increased defects. . In addition, since a skilled technician who can do argon welding is required, labor costs are incurred and the unit price of the product is increased, resulting in a problem of lowering productivity.

And in the conventional glasses, because a pair of rims and bridges are integrally manufactured and the temple is directly connected through the rim and hinges, if one side of the rim or the bridge or hinge is cut or damaged by impact, it is difficult to partially replace only the corresponding part. Inevitably, the need to purchase new glasses increases the economic burden on consumers, and there is a structural vulnerability that makes recycling of resources difficult.

Korean Patent Registration No. 10-1760431 discloses a wire elastic support type eyeglass frame made by winding or bending a wire made of an elastic material so that a pair of lenses can be detachably attached, including a frame, temples, and wire joints. This wire joint is provided with English C-shaped hinges, the third hinge of the temple is interposed between the first hinge and the second hinge of the eyeglass frame, and the first hinge and the third hinge. The first elastic friction portion is interposed therebetween, the second elastic friction portion is interposed between the third hinge and the second hinge, and then they are fastened to each other by the nut shaft portion and the bolt.

In this solution, since the hinges are formed at the ends of the wire of the thin wire, they can have a relatively light weight and slim glasses design compared to general eyeglass products, but elasticity between the hinges to achieve a stable folding operation of the temples. The friction part must be interposed. Such an elastic friction part is formed to extend each of the upper and lower friction parts in the radial direction from the upper and lower portions of the hollow disk-shaped core, and a friction pattern composed of a plurality of protrusions should be formed on the upper surface of the upper friction part or the lower surface of the lower friction part. Since the elastic friction part has to be manufactured with a complex structure of a fine size, the difficulty of processing increases and the productivity decreases as it acts as a factor of increasing the manufacturing cost.

In addition, the tightening motion of tightening the bolts to the nut shaft part for coupling the hinges and the elastic friction part must be properly performed.If the pressure of the hinge and the elastic friction part is excessively large due to the user's carelessness, it is difficult to rotate the glasses leg smoothly. When the elastic friction part is loosely coupled, there is a problem that the fit is deteriorated. Even if the bolts are properly fastened when assembling the glasses, if the pressing force is reduced by the repeated rotation of the temples, the user needs to tighten the bolts again, and the problem of the screw-fastening method still has the problem of the glasses hinge.

It is an object of the present invention to construct a spectacle hinge so that the rim of the lens is supported by bending a wire of a thin wire and the connecting members intersecting each other in the horizontal direction and the vertical direction are inserted and combined to prevent the spectacles from being screwed out.

members

140 and 320 to the hinge body 410 will be described.

Referring to (a) of FIG. 7, the cut groove 420 of the hinge body 410 provides a first passage 401 having an opening.

The second connecting member 320 extending from the temples 300 is fitted into the second fitting groove 147 of the hinge body 410 (see FIG. 7(b)). In detail, the connecting ring 321 is aligned inside the second passage 402. In this state, when the connecting ring 321 is pushed out, the elastic expansion portion 322 is slightly opened and inserted into the support column 416. In this way, the connecting ring 321 fitted in the support pillar 416 via the second passage 402 may horizontally rotate around the support pillar 416 in the second passage 402.

As shown in (c) of FIG. 7, the connecting ring 321 forms an opening with the expansion portion 322 open to the outside. When this opening is located at an intersection between the first passage 401 and the second passage 402, the bending portion 141 of the first connecting member 140 may be moved into the first passage 401. As the bending part 141 is moved into the first passage 401, a part of the first connecting member 140 is press-fitted into the first fitting groove 413, and the bending part 141 is inside the cut groove 420 It is press-fit into and fixed. At this time, the stopper 142 of the first connecting member 140 is located on the outside of the hinge body 410 close to the crossing area.

When the first connection member 140 is press-fitted and integrated to the hinge body 410, the hinge body 410 is constrained by the first connection member 140 to limit movement. It is possible to rotate the second connecting member 320 fitted in the second passage 402, at this time, since interference may occur in the detachable member 200, in a state where the detachable member 200 is separated from the support frame 100 The second connecting member 320 is rotated and moved in a clockwise direction. The rotation range of the second connecting member 320 is limited by the stopper 142, and at this time, the second connecting member 320 blocks the first passage 401 to limit the movement of the first connecting member 140 It can be done (see Fig. 7(d)).

Referring to FIG. 8, protrusions 419 for narrowing the distance between the first passage 401 may be formed on both sides of the hinge body 410 facing each other at the inlet 421 of the cutout groove 420 of the hinge body 410. The protrusion 419 is to prevent the first connecting member 140 coupled by force fitting through the first passage 401 from being separated from the hinge body 140.

As shown in FIG. 9, the hinge body 410 according to another embodiment may modify the structure of the incision groove 420 in order to maintain the folded state of the temples 300.

A press-fit space 424 is formed in the hinge body 410 from the inlet of the first passage 401 to the inside. An arc-shaped press-fit fixing portion 423 and a locking projection 422 are formed inside the press-fit space 424. When the first connection member 140 retreats from the press-fit fixing part 423 to the entrance of the first passage 401, it may be supported while being caught by the locking protrusion 422. This will be described in detail with reference to FIG. 10.

As shown in (a) of FIG. 10, when wearing glasses, the second connecting member 320 extending from the leg frame 310 of the temple 300 is spread at a substantially right angle with respect to the support frame 110. Here, the bending portion 141 of the first connecting member 140 coupled to the press-fit space 424 is fixed to the press-fit fixing portion 423.

When glasses are not worn, the leg frame 310 of the temples 300 is rotated toward the support frame 110, and the second connecting member 320 is positioned side by side in proximity to the support frame 110 (Fig. 10). (b)). In this state, when an external force is applied to the leg frame 310 to move toward the support frame 110, the bending portion 141 of the first connecting member 140 comes out of the press-fit fixing portion 423 and the locking projection 422 It is supported in a state that is hung on, and the connecting ring 321 is in close contact with the second fitting groove 417 of the hinge body 410, so that the temple 300 can be maintained in a folded state (Fig. 10(c)). Reference). Thereafter, when wearing glasses, the temples 300 are deployed by rotating the leg frame 310 in the reverse order.

As the folding or unfolding operation of folding or unfolding the temples 300 is frequently performed, the rotational resistance decreases due to friction between the connection ring 321 of the second connection member 320 and the support column 416, and eventually the glasses The temples 300 coupled to the hinge 400 may be loose. In the process of frequently folding and unfolding the temples 300 by the user, inconvenience in use may be felt.

As shown in FIG. 11, in another embodiment, the side cross-section of the support column 418 of the hinge body 410 may be formed in a V-shape. In this case, the inner surface of the connecting ring 321 of the second connecting member 320 fitted via the second passage 402 is in point contact with the V-shaped support column 418. Even if the operation of folding the temples 300 is repeated, the side cross-section of the support column 418 is transformed from a V-shape to a U-shape, and as the contact area with the connecting ring 321 increases, the temples 300 are smoothed. It is possible to maintain a rolling resistance suitable for folding for a long time.

Since the incision groove 420 and the second fitting groove 417 of the hinge body 410 are small in size and the outer surfaces of the upper plate 411 and the lower plate 414 are curved, When the first connecting member 140 and the second connecting member 320 are fitted and coupled, slip may occur. In consideration of this point, as shown in FIG. 12, the first and second connecting members 140 on the hinge body 410 are formed by cutting the inlet of the cut groove 420 of the hinge body 410 to form a cut surface 412. ) 320 can be easily fitted and coupled.

The above description of the present invention is for illustrative purposes only, and those of ordinary skill in the art to which the present invention pertains will be able to understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be.

The present invention can be applied to the manufacture of assembled eyeglasses that can be worn with temple legs such as vision correction glasses and sunglasses.
