Description

The present invention relates to a mechanism for a screwless hinge for eyeglasses. In particular, the present invention relates to a hinge mechanism for unthreaded eyeglasses having a good postcard.

Conventionally, as a hinge of glasses, a hinge in which a female piece portion and a male piece portion are fitted and screwed with a screw has been most frequently used. Among them, in order to produce a good postcard (sliding frictional resistance), for example, techniques such as actual all Showa 55-41869 and actual fairness 6-48487 have been proposed.

Actually Showa 55-41869 Reality 6-48487

However, as shown in FIG. 9 and FIG. 10, which is the prior art, generally, when the female piece 101 and the male piece 102 are fitted and screwed with the screw 103 and the temple is rotated, What comes to mind is that the screw is firmly tightened to produce a postcard on the sliding surface S between the female piece and the male piece, but this method is actually the 11th page of specification 1 of Showa 55-41869. As described in lines 16 to 16, this is not a preferable method. The screw on the sliding surface S is likely to cause the screw to rotate, and it is easy to cause an accident that the screw is overtightened and loosened and dropped off. Therefore, as disclosed in Patent Document 2, it has been disclosed and proposed to stably produce a postcard at the surface H where the screw hole 105 of the male piece portion and the screw shaft 106 contact when the temple rotates. And that has become a recent mainstream idea. However, with the recent miniaturization of parts, the contact area J becomes smaller as the parts such as screws become smaller, and the rate at which the frictional force becomes smaller and the postcard becomes smaller becomes higher. On the other hand, when the diameter of a screw or the like is increased, the contact area is increased, the frictional force is increased, and the postcard is increased. However, as shown in FIG. Become worse. For that reason, recently, large screws are not used.

Therefore, in the present invention, it is possible to increase the area of the frictional sliding surface without using a screw that is tightened or loosened, and has a good touch to the finger with minimal protrusion to the inside. In addition, in order to provide a hinge with excellent design, first, a cross-shaped opening is formed at one end for connecting either a Yoroi part or a temple part made of a stamped metal plate used vertically. The other end for connection, which is not provided with an opening, is provided with a cylinder provided with a columnar through-hole vertically, and is fitted into the column-shaped through-hole and the cross-shaped A fitting grooved pin that fits in each of the upper and lower sides of the opening and a cylinder with a lid having a fitting groove, and a coil spring for pressing and fixing them between the upper and lower sides of the cross-shaped opening. A combination axis is provided, and the combination axis is As heart, spectacle hinge mechanism, characterized in that the temple part is openably rotate.

Next, a cross-shaped opening is provided at one end of the connection for either a Yoroi part or a temple part made of a punched metal plate used vertically, and the other connection for which no opening is provided. At one end of the cylinder, there is provided a cylinder provided with a columnar through-hole vertically, and fitting grooves that are fitted into the column-shaped through-hole and are respectively fitted to the upper and lower sides of the cross-shaped opening. A combination shaft comprising an upper and lower cylindrical body with a lid and a coil spring sandwiched between the upper and lower cylindrical bodies and compressing and fixing the upper and lower cylindrical bodies to the upper and lower sides of the cruciform opening; A hinge mechanism for spectacles characterized in that the temple part is rotated so as to be openable and closable as a center.

And then, a cross-shaped opening is provided at one end for connection of either an alloy part or a temple part made of a punched metal plate used in the vertical direction, and the other part where no opening is provided. One end of the coupling is provided with a cylinder provided with a columnar through-hole vertically, and fitted into the upper and lower sides of the cross-shaped opening by being fitted into the column-shaped through-hole. It comprises a grooved upper and lower pin body, a coil spring sandwiched between the upper and lower pin bodies to compress and fix the upper and lower pin bodies on the upper and lower sides of the cross-shaped opening, and an inner cylindrical body for covering the coil spring and producing a postcard A hinge mechanism for glasses is provided, wherein a combination shaft is provided, and the temple part is rotated about the combination shaft so as to be opened and closed. It is also possible to attach them to separate metal or resin alloy parts or temple parts.

By adopting the above mechanism, it is possible not to overtighten or loosen the screw by not using the screw first, it is possible to generate agitation as appropriate when the temple rotates, and there is no bulge inside, It is now possible to provide a hinge structure for glasses that is refreshing in terms of design. Furthermore, it is also important to be able to easily assemble and disassemble without using screws.
