Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial Field of Use The present invention relates to a temple for eyeglasses that facilitates the insertion of a metal core into the center of the temple of the eyeglasses.

Conventional technology Traditionally, the temples of eyeglass mirrors are integrally constructed with a core bar having a hinge made of a plastic material such as synthetic resin. For this reason, the work of positioning the core metal requires a high degree of skill and requires a precise positioning jig.

Problems to be Solved by the Invention The present invention uses a groove formed in a hinge formed at the tip of a metal core and a protruding wall part formed on the elastic body to fit into the groove, and the elastic body is fitted into the groove. In the eyeglasses, a temple is formed by fitting a step formed at the tip of a latching rod to the rear end of the elastic body, and the core bar is easily positioned at the center of the temple. It is intended to provide vines.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention forms a flat substrate at the tip of the core metal, integrally forms a hinge on one side of the substrate via a connecting portion, and connects the metal core with a hinge. A groove is formed on both sides of the connecting part in the longitudinal direction of the connecting part to form a hinge part, and the groove is continuous with the hinge part and extends toward the rear end of the core metal and is inclined with respect to the axial direction of the core metal. A retaining part is formed with a serrated engagement protrusion, one side of the rectangular pipe-shaped elastic body is cut out with a projecting wall part so as to fit into the groove of the hinge part, and the hinge part of the core metal is cut out. A temple for eyeglasses in which an elastic body is attached to the rear end of the elastic body, and a stepped part formed at the tip of a synthetic resin hanging rod is fitted to the rear end of the elastic body to cover the rear end of the core bar to the maintenance part. This is an attempt to solve the above-mentioned drawbacks by providing the following.

Function The present invention integrates the core metal and the elastic body by closely fitting the projecting wall of the elastic body into the groove of the hinge of the core metal, and in this connected state, a hanging rod is attached to the rear end of the elastic body. By fitting the stepped parts of the metal core and covering the metal core, the metal core is placed in the center of the temple, and the locking rod engages with the serrated protrusion of the retaining part to secure the shaft of the metal core. To resist the tensile force in the direction of the heart,
The core bar and latch rod are firmly integrated.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a temple in eyeglasses, which is composed of a metal core 2, an elastic body 3, and a hanging rod 4.

The core metal 2 has a flat base plate 12 formed at its tip, and a hinge 9 is integrally formed on one side of the base plate 12 via a connecting part 13. A groove 8 is formed extending in the longitudinal direction to form a hinge part 5, and a resilient part 6 is formed continuous with the hinge part 5 and rolled into a thin plate shape so as to be elastically bent in the opening/closing direction of the temple 1. Furthermore, a sawtooth-shaped sawtooth is provided continuously on both sides of the resilient portion 6 over a predetermined width, and is inclined toward the rear end of the cored metal 2 and with respect to the axial direction of the cored metal 2. A maintenance portion 7 having engaging protrusions 14, 14a, . . . is formed.

The elastic body 3 is made of elastic plastic or the like, and is made to bend elastically in the opening/closing direction of the temple 1. The elastic body 3 is formed into a square pipe shape, and the entire tip of one side of the elastic body 3 is cut out. , the protruding wall portions 15, 15 are fitted in the groove 8 of the hinge portion 5.
a, and a fitting groove 10 is formed inside the projecting wall portions 15, 15a, and the elastic body 3 is formed so as to surround the resilient portion 6 of the core bar 2 in the upper fitted state. There is.

In this embodiment, the elastic body 3 is shown as having a square pipe shape, but it is not limited to this type, and any shape that fits into the groove 8 of the hinge portion 5 may be used. good.

Further, the area from the rear end of the core bar 2 to the maintenance part 7 is covered with a hanging rod 4 made of synthetic resin such as acetate, and a stepped portion 11 formed at the tip of the hanging rod 4 is connected to the back of the elastic body 3. The elastic body 3 is fitted and fixed between the hinge portion 5 and the locking rod 4 by fitting the end thereof.

Next, to explain the effect of the temple in the glasses according to the present invention, the projecting wall portion 1 of the elastic body 3 is placed in the groove 8 of the hinge portion 5 of the core metal 2.
5 and 15a are tightly fitted together, the core bar 2 and the elastic body 3 are integrally coupled, and in this coupled state, the step portion 11 of the locking rod 4 is fitted to the rear end of the elastic body 3, and the core bar 2 is attached. By integrating the covering, the core 2 is placed in the center of the temple 1.

In addition, since the locking rod 4 coated on the core metal 2 engages with the serrated engagement protrusions 4, 14a, etc. of the maintenance part 7, it resists the tensile force in the axial direction of the core metal 2. The metal 2 and the latch rod 4 are firmly integrated.

[Effect of idea]

In short, the present invention forms a flat base plate 12 at the tip of the core metal 2, integrally forms the hinge 9 on one side of the base plate 12 via a connecting part, and has hinges 9 on both sides of the connecting part 13. A groove 8 is formed extending in the longitudinal direction of the connecting part 13 to form a hinge part 5, and is continuous with the hinge part 5 and extends toward the rear end of the core metal 2, and also extends in the axial direction of the core metal 2. A retaining part 7 is formed having sawtooth-like engaging protrusions 14, 14a, etc., which are inclined at the same time. ,1
5a, the elastic body 3 is attached to the hinge part 5 of the core metal 2, and the step part 11 formed at the tip of a synthetic resin locking rod 4 is fitted to the rear end of the elastic body 3. Since the area from the rear end of the core bar 2 to the maintenance part 7 was covered, the core bar 2
The protruding wall portions 15, 15 of the elastic body 3 are placed in the groove 8 of the hinge portion 5 of
a to closely fit the core metal 2 and the elastic body 3, and further fit the step 11 of the locking rod 4 to the rear end of the elastic body 3 to cover and integrate the core metal 2, Since the core metal 2 can be installed in the center of the temple 1, there is no need for a precise positioning jig, which simplifies the work process and facilitates manufacturing.

Further, the core bar 2 and the locking rod 4 are firmly integrated against the tensile force in the axial direction of the core bar 2 by engaging the serrated engagement protrusions 14, 14a, . . . of the maintenance part 7. Therefore, there is no fear that the locking rod 4 will come off or become misaligned due to bending of the core metal 2, and the practical effects thereof are extremely great.
