The temple length adjusting device 100 of an eyeglass frame according to the present invention includes a hinge connecting member 110, a length adjusting member 120, and a hanging member 130.

The hinge connection member 110 is a part that is hingedly connected to the main front 200 of the eyeglass frame, and is provided with a main front connection part 111 hinged to the main front 200 at the front end, and a length adjustment member 120 at the rear end. ) is provided with an elastic coupling portion 112 to which it is connected.

The elastic coupling portion 112 is provided with a rectangular separation hole 113 with a short vertical length and a long horizontal length at the top, and is separated on both sides of the lower front of the separation hole 113 and both sides of the lower rear of the separation hole 113. It has an elastic groove 114 connected to the hole 113, and has a disc-shaped locking protrusion 115 protruding from the front center.

The front of the elastic coupling portion 112 is formed parallel to the front of the main body of the hinge connection member 110, and accordingly, the disk-shaped locking protrusion 115 protrudes in front of the main body of the hinge connection member 110.

The thickness of the elastic coupling portion 112 is formed to be thinner than the thickness of the main body of the hinge connection member 110, and accordingly, the rear of the elastic coupling portion 112 is located forward of the rear of the main body of the hinge connection member 110. When the length adjustment member 120 is connected to the hinge connection member 110, a separation space (S) is formed between the inner rear surface of the length adjustment member 120 and the rear surface of the elastic coupling portion 112.

The length adjustment member 120 is a part that adjusts the position of the hanging member 130 in the forward and backward directions, and is installed on the hinge connection member 110 to be movable in the forward and backward directions.

The length adjustment member 120 has a hollow shape into which the rear portion of the hinge connection member 110 is inserted, and has a plurality of locking holes 121 on the front into which the disk-shaped locking protrusions 115 of the elastic coupling portion 112 are inserted. It is arranged in the left and right directions, and has a fitting bar 122 on which the hanging member 130 is assembled at the rear end.

Attachment protrusions 122a are formed at the upper and lower ends of the insertion bar 122 to enable the hanging member 130 inserted into the insertion bar 122 to be more firmly fixed.

The hanging member 130 is a part that comes into contact with the wearer's ears when wearing glasses, and is coupled to the rear end of the length adjustment member 120 through the fitting hole 131 provided at the distal end.

In the temple length adjusting device 100 of an eyeglass frame according to the present invention, the hinge connecting member 110 and the length adjusting member 120 are preferably made of plastic material with good rigidity and elasticity, and the hanging member 130 is in contact with the wearer's ear. It is preferable that it is made of a material such as rubber or silicone that has a good contact feeling and excellent resilience.

The illustrated embodiment is a form in which a hanging member 130 made of different materials is assembled to the length adjusting member 120, but in the temple length adjusting device 100 of a spectacle frame according to the present invention, the length adjusting member 120 and the hanging member 130 are used. ), of course, can be constructed as an integrated piece of the same material.

The temple length adjusting device 100 for an eyeglass frame according to the present invention is one in which the length adjusting member 120 is assembled to be movable in the forward and backward directions at the rear portion of the hinge connection member 110 that is hinged to the main front 200. When the length adjustment member 120 is moved forward, the hanging member 130 is moved forward, allowing the overall length of the temple to be set shorter, and when the length adjustment member 120 is moved rearward, the hanging member 130 is moved forward. is moved to the rear, making it possible to set the overall length of the temple longer.

Figures 6a and 6b are diagrams illustrating the temple length adjustment state of the temple length adjusting device for an eyeglass frame according to the present invention.

When assembling the length adjustment member 120 to the hinge connection member 110 hinged to the main front 200 in the temple length adjustment device 100 of an eyeglass frame according to the present invention, the distal end of the hollow length adjustment member 120 After inserting into the rear end of the hinge connection member 110, push the length adjustment member 120 toward the front end of the hinge connection member 110 to remove the disk-shaped locking protrusion 115 of the elastic coupling portion 112 of the hinge connection member 110. ) can be inserted into one of the plurality of locking holes 121 of the length adjustment member 120.

Figure 6a shows a state in which the disk-shaped locking protrusion 115 of the hinge connection member 110 is coupled to the first locking hole 121. At this time, the length adjustment member 120 and the hook member 130 are moved to the rearmost. The length of the temple becomes the maximum length.

When it is desired to reduce the length of the temple in the maximum extension state of Figure 6a, when the length adjustment member 120 is pushed forcefully toward the main front 200, the elastic coupling portion 112 and the disk-shaped locking protrusion between the elastic grooves 114 ( 115) moves outward and comes out of the first locking hole 121, and then is elastically coupled to the second locking hole 121, allowing the length of the temple to be first reduced, and once again attaching the length adjustment member 120 to the main front. When pushed forcefully toward (200), the disk-shaped locking protrusion 115 of the hinge connection member 110 is elastically coupled to the third locking hole 121, as shown in FIG. 6c, allowing the length of the temple to be reduced a second time.

As shown in Figure 6c, when the disk-shaped locking protrusion 115 of the hinge connection member 110 is coupled to the first locking hole 121, the length adjustment member 120 is pushed toward the main front 200 to make the fourth locking hole ( When the disk-shaped locking protrusion 115 is elastically coupled to 121), the length of the temple can be further reduced, and the length adjustment member 120 is pulled to the opposite side of the main front 200 to create a disk-shaped lock in the second locking hole 121. When the locking protrusion 115 is elastically coupled, the length of the temple can be extended.

In this way, the temple length adjusting device 100 of an eyeglass frame according to the present invention can shorten or extend the length of the temple by simply pushing the length adjusting member 120 toward the main front 200 or pulling it in the opposite direction to the main front 200. This makes it possible to easily adjust the length of the temple.

In addition, the temple length adjusting device 100 of an eyeglass frame according to the present invention has only an elastic coupling portion 112 provided with a disc-shaped locking protrusion 115 through a separation hole 112 and an elastic groove 114 in the outer and inner directions. It expands and contracts, and the disk-shaped locking protrusion 115 is elastically inserted into the locking hole 121, making it possible to firmly maintain the length adjustment state of the temple.

Although the invention made by the present inventor has been described in detail according to the above-mentioned embodiments, the present invention is not limited to the above-described embodiments and can of course be changed in various ways without departing from the gist of the invention.
