Abstract

PURPOSE:To provide the spectacles having spring type temples constituted to have >=90 deg. opening angle of the temples and to be adaptable even to a person having the broad face or person having the harrow face by imparting some spring force in the closing direction of the temples. CONSTITUTION:Mounting parts 3b of the temples 3 are formed of two wires and are provided with detaining pieces 3c, 3d by bending the front ends of these two wires. Bracket members 2 disposed at a spectacle frame 1 are juxtaposed with two pieces of engaging holes 2a, 2b nearly along the transverse direction of the spectacle frame 1 and the detaining pieces 3c, 3d of the mounting parts 3b are respectively fitted into two pieces of these engaging holes 2a, 2b, by which the temples 3 are mounted. The temple bodies are formed to double wires by one piece of the wire and the mounting parts 3b are formed by respectively providing the beginning end part and terminal part with the detaining pieces 3c, 3d.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to eyeglasses having a spring type temple.

[0002]

2. Description of the Related Art Generally, temples of spectacles are fastened with a small screw to hinge fittings attached to both sides of a frame and can be opened and closed within a range of about 90 degrees.
When selecting an eyeglass frame, it is necessary to consider not only the design and material, but also a size suitable for one's face width and eye distance.

[0003]

However, the opening angle of the temple is limited to the range of about 90 degrees as described above, and since it does not open any more, it may not be suitable for a person with a wide face. On the contrary, for a person whose face width is narrower than the standard, the temple opening angle is too large, but the temple cannot be held at a smaller opening angle because the temple is completely opened and becomes stable. Therefore, it is necessary to make adjustments such as bending the ear pads of the temples or bending the middle portions of the temples to match the face width. The present invention is made in order to eliminate such a conventional inconvenience, the temple can be opened at an angle of 90 degrees or more, and a spring force is applied to the closing direction to some extent to make it suitable for people with wide face and narrow face. It is an object of the present invention to provide eyeglasses having a spring-type temple, which can be adapted to.

[0004]

As a means for technically solving this problem, according to the present invention, the temple attachment portion is formed of two wire rods, and the ends of the two wire rods are bent to engage. Stop pieces are provided respectively, and two engaging holes are provided in parallel in the receiving member provided in the spectacle frame substantially along the width direction of the spectacle frame, and the engaging pieces of the mounting portion are provided in these two engaging holes. The gist is that the temples are attached by inserting the respective parts. Furthermore, the temple body is 1
The gist of the present invention is to form a double wire from a single wire rod, and provide the locking pieces at the starting end and the terminating end thereof to form a mounting portion.

[0005]

[Operation] When the temple is closed, the direction of the temple attachment part matches the parallel direction of the two engaging holes of the receiving member, so no spring force is generated in the temple, but the temple is open. Since the direction of the temple mounting portion is perpendicular to the parallel direction of the two engaging holes, and the fitting position of the locking piece is laterally displaced, there is a difference in the rotation angle between the two wire members of the temple mounting portion. The difference causes a spring force in the closing direction of the temple. Also, the temple opening angle is almost 90
The opening angle is not limited to a certain degree, and a larger opening angle is possible.

[0006]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is a metal spectacle frame, and receiving members 2 for attaching temples are provided on both sides of the frame. The receiving member 2 has a substantially C-shape as shown in FIG. Two engaging holes 2a, 2b
Are arranged side by side substantially along the width direction of the spectacle frame 1.

Reference numeral 3 is a temple, which is 1 as shown in FIG.
It is formed by bending a double wire with a single metal wire rod, and a winding part 3a in which a lower wire is wound around an upper wire is provided at a slightly tip end side from the middle, and a starting end is provided at a mounting part 3b at the tip end. The portion (upper line) is bent downward to form the locking piece 3c, and the end portion (lower line) is bent upward to form the locking piece 3d.
The downward locking piece 3c is located slightly inside (the winding portion 3a side) of the upward locking portion 3d.

In the temple 3, the downward engaging piece 3c of the mounting portion 3b is fitted into the engaging hole 2a of the receiving member 2 from above, and the upward engaging piece 3d is fitted into the other engaging hole 2b from below. By doing so, it can be attached to the spectacle frame 1.

When the temple 3 is in the closed state, as shown in phantom in FIG.
Since the two engaging holes 2a, 2b of the above are aligned in the parallel direction, no spring force is generated in the temple 3, but in the opened state, as shown by the solid line in FIG. The two engaging holes 2a, 2b of 2 are parallel to each other at a right angle, and there is a difference in the opening angle of the two lines of the mounting portion, so that a spring force is generated in the temple 3.

That is, the locking piece 3 of the mounting portion 3b of the temple 3
c and 3d are fitted into different engaging holes 2a and 2b as described above, and these engaging holes 2a and 2b are displaced in the lateral direction (the width direction of the spectacle frame 1), so the locking piece 3c. There is a difference between the opening angles θ ₁ and θ ₂ between the upper wire with the formed wire and the lower wire with the locking piece 3d, and this difference causes a rotational torque to return the temple 3 in the closing direction. A spring force is generated.

This spring force gradually becomes stronger as the temple 3 is opened, but it is not so strong that the face is strongly tightened or pressed, so that no trouble occurs when wearing the spectacles. Further, unlike the conventional hinge connection, the opening angle of the temple 3 is not limited to the range of about 90 degrees, and the temple 3 can be opened to a larger angle.

Therefore, the present invention can be applied to both wide and narrow face persons, and the stability of the temples and the condition of the ear pads are improved, so that the comfort of wearing the glasses is improved and the temples are damaged by external force or the like. Can be prevented in advance. When the temple 3 opens at a large angle, distortion occurs, but the distortion is self-absorbed by the elastic deformation of the temple 3 itself.

Further, since the temple 3 is mounted only by fitting the locking piece of the mounting portion into the engaging hole of the receiving member as described above, the conventional small screw is unnecessary and the production efficiency is improved. At the same time, it is possible to prevent inconvenience in use such as rattling of the temple due to loosening of the screw and detachment of the temple by removing the screw.

Since the temple 3 has an extremely simple structure in which one wire is bent to form a double wire, the manufacturing cost can be reduced, and the design is novel and excellent, lightweight and easy to use. It also has functions such as. The temple is not limited to that of the embodiment, and the temple mounting portion of the conventional form is formed by two wire rods, and the tips of the two wire rods are bent to provide locking pieces. It is possible.

[0015]

As described above, according to the present invention,
The temple opening angle is 90 degrees or more, and a certain amount of spring force is applied in the closing direction, so it can be adapted to people with wide and narrow faces. There is an excellent effect such that adjustment such as bending of the contact portion or bending of the middle portion of the temple becomes unnecessary.
