Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eyeglass frame, and more particularly to a coupling mechanism in which a temple of the eyeglass frame is detachably attached.

[0002]

[Prior art]

 The temple of the spectacle frame is attached to the end of the spectacle by a hinge. On the other hand, however, there is demand for temple replacement. The temples are extremely thin parts that may be broken or have less elasticity to pinch the head from the left and right. Moreover, since the temples are constantly in contact with the hair, the plating is easy to peel off. In such cases, there is a desire to use the other parts as they are and replace only the temples. If the temples do not fit together, or if temples with different designs are installed, only the temples may be replaced.

[0003]

[Problems to be solved by this device]

 In the case of such replacement demand, if the temple is attached by the hinge as described above, the removal and attachment thereof are troublesome. Also, if the screws are removed many times, the screws may become loose and the frame may rattle. In such a spectacle frame, the temple may be detachably attached, but if the joint portion of the temple and the armor is too large, the appearance of the spectacle frame as a whole will not be good.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a compact eyeglass frame temple coupling mechanism that is easy to attach and detach, and that does not impair the appearance of the entire frame. To aim.

[0005]

[Means for Solving the Problems]

 In the eyeglass frame temple coupling mechanism according to the present invention, the coupling mechanism that allows the temple to be attached to and detached from the armature also functions as a conventional hinge. A spherical rotating ball is formed at the tip of the temple. The rotating sphere is formed with two fixed surfaces that form a substantially right angle to the tip and to the side thereof. Substantially the fixed faces do not necessarily intersect, but two extended faces with a slight gap may intersect. The part that is continuous with the rotating sphere is the temple neck, and two parallel planes are formed vertically. A cylindrical coupling case is provided on the end side, and a coil spring and a pressing member that is pushed by the spring force of the coil spring and slides in the coupling case are housed in the coupling case. A continuous cutout is provided on the end face and side face of the coupling case, and a part of the side face opening of this cutout is large enough for the rotating ball at the tip of the temple to pass through. There is. The other part of the notch opening is a temple neck or a slit that allows passage. When connecting the temples, the rotating ball is stored inside through the notch opening and held by the holding member that is biased by the spring. The temple can rotate around a rotating ball.

[0006]

[Action]

 When the rotating ball is housed in the joint case, it is held by the pressing member urged by the spring, so that it does not separate from the joint case. It is possible to fold the temple around the rotating ball by passing the temple neck through the slit part of the cutout opening and folding the temple toward the lens. When detaching the temple, push the pressing member back with the temple and remove it from the notch opening to the outside of the joint case.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. In the figure, 1 is a metal temple, and a spherical rotating ball 2 is formed at the tip. Two fixed surfaces 3 and 4 whose extension surfaces intersect each other at a substantially right angle are formed at the tip and side of the rotating ball 2. The part that is continuous with the rotating ball 2 is the neck part 5 of the temple 1, and two flat surfaces 6 and 6 that are parallel in the vertical direction are formed to the desired length.

A cylindrical joint case 9 is formed on the side of the armature 8 attached to the side of the rim 7. A coil spring 10 and a columnar pressing member 11 urged by the coil spring 10 are housed in the joint case 9. The pressing member 11 is movable in the coupling case 9 while being pressed by the coil spring 10. The end face and the side face of the joint case 9 have a notch opening 12 that is continuously opened. A part 13 of the opening on the side surface of the notch opening 12 is sized so that the rotating ball 2 of the temple 1 can pass therethrough. The other portion of the notch opening 12 is a slit portion 14 through which the thickness of the two flat surfaces 6 of the neck portion 5 of the temple 1 can finally pass.

When the temple 1 is attached to the armor 8, the rotating ball 2 of the temple 1 is put into the joining case 9 from a part 13 of the cutout opening 12. The pressing member 11 pushes the spring 10 back by the rotating ball 2 and retracts it. The neck portion 5 of the temple 1 is extended to the outside of the case 9 through the slit portion 14. The fixed surface 3 at the tip of the rotating ball 2 comes into contact with the pressing member 11, and the temple 1 stands still. At this time, the fixed surface 4 is directed toward the other facing temple 1. The neck 5 of the temple 1 has two parallel flat surfaces 6 and 6 which are fitted in the slit portion 14 so that the temple 1 does not rotate about its axis. In other words, the angle of Modern at the other end of Temple 1 does not change arbitrarily. When folding the temple 1 toward the lens side, the temple 1 is rotated around the rotation ball 2 and tilted toward the lens side. At this time, the neck portion 5 of the temple 1 passes through the slit portion 14. The pressing member 11 comes into contact with the fixed surface 4 formed on the side of the rotating ball 2 to stop the rotation.

When removing the temple 1, the temple 1 is pushed to push back the pressing member 11, the rotary ball 2 is passed through a part 13 of the cutout opening 12 of the coupling case 9, and the neck portion 5 is passed through a slit portion 14. The joint case 9 is detached. When the temple 1 is replaced, as described above, the rotating ball 1 of the temple 1 is put into the joint case 9 through the notch opening 12, and the pressing member 11 prevents the detachment.

[0011]

EFFECTS OF THE INVENTION The present invention has the above-mentioned configuration and can obtain the following effects. The temple can be easily attached to and detached from the armor by simply inserting and removing the rotating ball at the tip of the temple from the opening into the joint case, and the temple can be replaced and repaired. The attachment and detachment can be done only by pushing back the coil spring in the joint case, so there is no need to loosely tighten the screws, and there is no rattling even when attaching and detaching multiple times. The temple can be stretched or folded around the rotating sphere at the tip of the temple, and the fixed surface formed on the rotating sphere makes it difficult to rotate the temple in place. Two parallel planes are formed on the neck of the temple, and these are fitted in the slits of the notch opening so as not to rotate about the axis of the temple. The coupling mechanism not only joins the temple and the armor, but also plays the role of a hinge due to the rotating ball and the fixed surface of its surface.It is a compact structure that does not differ from conventional hinges and does not become large. , The appearance of the entire spectacle frame is not impaired. Since the coil spring, the pressing member, and the rotating sphere of the temple are housed side by side in the coupling case, the coupling mechanism has a slim appearance.
