[First Embodiment] In the drawing, the one designated by reference numeral L is a pair of left and right spectacle lenses, and a peripheral groove of the left and right lenses L has a fitting groove LC into which a rim R is fitted. Are drilled. The rim R fitted into the fitting groove LC is formed by bending a metal round wire into a loop shape in accordance with the shape of the lens L as shown in FIG. The ends of the wire are located at the left and right outer ends of the spectacle front formed by the rims RR.

In the figure, what is indicated by reference numeral 1 is two locking pins formed on the outer end of the rim R, respectively.
These locking pins 1.1 are in a parallel relationship with each other. In the present embodiment, the locking pins 1.1 are formed by bending the distal end of a rim R formed of a metal round wire to the outside of the glasses at substantially right angles. The rims R are each formed in a continuous line shape.

In the figure, what is indicated by reference numeral 2 is a substantially cylindrical fastening member formed of a polyurethane resin material.
On the peripheral side surface of the one fixing member 2, the locking pins 1
Two fastening holes 21 to which 1 is to be inserted are formed. These two fastening holes 21 have a parallel relationship to each other and are provided at substantially the same interval as the interval between the two locking pins 1.1. Further, at a position between the two fastening holes 21 on the peripheral side surface of the fastening member 2, a guide groove 22 into which a hook portion 31 described below is rotatably fitted is provided. Are provided.

In the figure, the one designated by the symbol T is an ear-hanging temple. At the base end of this temple T, a superior arc-shaped member to be removably fitted in the guide groove 22 of the fastening member 2. A hook portion 31 is formed, and a vertical stopper portion 32 is brazed to a protruding end of the hook portion 31 so as to form a T-shape. Note that the hook portion 31 of the present embodiment is formed by bending the tip of a temple T made of a metal wire into an excellent arc shape.

In this embodiment, the screwless hinge mechanism integrated with a rim lock is configured such that the hook portion 31 of the temple T is attached to the fastening member 2.
And this one fastening member 2 is connected to the locking pin 1.1
It is assembled by being detachably fitted to the device. This will be described in detail below.

First, a hook portion formed at the base end of the temple T
31 is detachably fitted into the guide groove 22 of the fastening member 2. Thus, the fastening member 2 serves as a rotation axis of the hinge connection mechanism, and the temple T is hinged so as to be freely rotatable. At this time, if the arc diameter of the superior arc-shaped hook portion 31 is formed to be slightly smaller than the diameter of the guide groove 22 of the fastening member 2, the bending elasticity of the hook portion 31 and the polyurethane resin are formed. Due to the frictional resistance caused by the elasticity of the fastening member 2, an appropriate opening / closing operation resistance (so-called agaki) of the temple T can be easily obtained.

Next, the rim R is fitted into the fitting groove LC to hold the lens L, and the locking pin 1.1 of the rim R is inserted into the fixing hole 21 so as to pass through the fixing member. 2 is detachably fitted to the locking pin 1.1. This allows
The ends of the rim R are connected and fixed by one fastening member 2 via the locking pins 1.1, and the lens 1 is securely held by the rim R. At this time, if the diameters of the fixing holes 21 are slightly smaller than the wire diameter of the locking pins 1.1, the frictional resistance generated by the elasticity of the fixing member 2 made of polyurethane resin causes the engagement to be reduced. It is possible to prevent the fixing pins 1 and 1 from being easily fitted to the fixing member 2.

Abuts against the locking pin 1 of the rim R to restrict the opening operation of the temple T to a required angular position.

The opening restriction of the temple T by the stopper portion 32 is elastically performed by the spring property in the expanding direction of the hook portion 31 having a superior arc shape (see FIG. 6). Therefore, for the temple T in the expanded state,
Furthermore, even if any external force is applied in the expanding direction, the hook portion 31 absorbs the external force and can avoid concentration of stress on the rim R. It is also possible to prevent the lens loss due to the rim deformation particularly seen in the conventional narrow frame eyeglass frame.

In this embodiment, as described above, the guide groove 22 is provided on the peripheral side surface of the fastening member 2 to guide the turning operation of the hook portion 31 fitted therein. The formation of the guide groove 22 is not essential. In other words, as shown in FIG.
Since the pin 31 is sandwiched between the two locking pins 1.1, even if the guide groove 22 is not provided, the hook
This is because the vertical displacement of 31 can be regulated by these two locking pins 1.1. The formation of the guide groove 22 can be selected in accordance with the design change of the interval between the locking pins 1.1 and the interval between the fastening holes 21.

The horizontal cross-sectional shape of the guide groove 22 (or the portion between the fastening holes 21 of the fastening member 2) and the shape of the hook portion 31 are circular in this embodiment. However, the present invention is not limited to this and can be changed to another shape. For example, if the shapes of the guide groove 22 and the hook portion 31 are formed in the same polygonal shape, the hook portion 31 can be elastically deformed in the spreading direction as described above,
The turning operation of the hook portion 31 about the fastening member 2, that is, the opening and closing operation of the temple T is performed in a stepwise turning state having a plurality of elastic stable points at required angular positions in a ticking manner. Is also possible.

As described above, in the hinge of this embodiment,
The rim R can be rim-locked and the temple T can be hinged by only an extremely simple operation of fitting the hook portion 31 to the fastening member 2 and fitting this one fastening member 2 to the locking pin 1.1. The rim lock mechanism and the hinge mechanism can be connected to the rim lock screw or butterfly.
Use small screw (screw) such as No. screw at all
Not in. Therefore, the assembling work becomes much easier as compared with the conventional product, and the eyeglass manufacturing cost can be greatly reduced.

Further, the hinge of this embodiment can easily perform the lens removing operation. As shown in FIG. 6, the ear hanging temple T may be opened further outward than the expansion restriction position by the stopper portion 32. Then, with the abutment between the stopper part 32 and the locking pin 1 as a fulcrum, the hook part 31 spreads and the hook part 31 and the fastening member 2
Can be disengaged. As described above, since no troublesome operation is required for the lens removing operation, for example, anyone can easily perform the lens replacing operation.

Furthermore, in the hinge of this embodiment, the rim lock mechanism of the rim R and the hinge connection mechanism of the temple T are only one.
