Description

The hinge structure of glasses

The present invention relates to a hinge structure of spectacles, in particular to a hinge structure of spectacles for connecting the temples of the spectacles to the spectacle frame or the lens.

Existing glasses usually use hinges to connect the temples of the glasses to the frame or lens, so that the temples of the glasses can be folded and folded, or the relative inclination angle between the temples and the lenses can be adjusted.

The hinges used in the existing glasses temples usually use friction to locate the rotation angle of the anklet. However, the friction positioning method usually has insufficient positioning force and cannot fix the relative angle between the temple and the glasses, thus causing the inconvenience of using the glasses. In addition, a part of the hinges are provided with teeth or engagement bumps for positioning the rotation angle. However, the engagement force of the teeth or engagement bumps is not easy to control, so the angle adjustment is not easy, and it is easy to wear and tear, resulting in reliable reliability.

The end of the engaging member 120 has a curved elastic arm 130 , and the end of the elastic arm 130 has a locking portion 131 in the shape of concave-convex teeth.

The second connection base 200 is connected to the side of the first connection base 100 opposite to the glasses body 300 , the second connection base 200 has a second body 210 , and the second body 210 faces the eyeglasses body 300 . An arc-shaped convex portion 214 corresponding to the arc-shaped concave surface 113 is formed on one side of the first connecting seat 100 , and the arc-shaped convex portion 214 can be connected with the arc-shaped concave surface 113 . A receiving groove 212 is formed on the inner side of one end of the second body 210 facing the first connecting seat 100 , the receiving groove 212 has an opening facing the first connecting seat 100 , and the receiving groove The inner diameter of the engaging member 212 is designed to be larger than the outer diameter of the engaging member 120 , so that the engaging member 120 can be accommodated, and the engaging member 120 can swing back and forth inside the accommodating groove 212 .

The second body 210 is provided with a pivot hole 211, the center of the pivot hole 211 falls on the rotation axis C1, and the hinge pivot 121 of the first connection base 100 can be pivoted to The pivot hole 211 enables the first connection base 100 and the second connection base 200 to rotate relative to the rotation axis C1 .

One side of the second body 210 opposite to the receiving groove 212 is provided with a temple connecting portion 213 , so that the temple 400 can be fixedly connected to the temple connecting portion 213 , so that the temple 400 is connected to a side of the second connection base 200 opposite to the first connection base 100 .

In addition, as shown in FIG. 4 and FIG. 5A , the accommodating groove 212 has a side wall 215 substantially parallel to the longitudinal axis direction C2 , and a rack 220 is provided on the side wall 215 correspondingly. The rack 220 is located at a position of the side wall 215 corresponding to the locking portion 131 at the end of the elastic arm 130 , so that the locking portion 131 at the end of the elastic arm 130 can be connected to the rack 220 mesh.

As shown in FIG. 5A and FIG. 6 , the first connecting seat 100 and the second connecting seat 200 are configured such that when the first connecting seat 100 and the second connecting seat 200 are assembled together, the elastic The locking portion 131 at the end of the arm 130 can engage with the rack 220 in an interference fit manner, and since the first connecting seat 100 is made of elastic plastic material, the end of the elastic arm 130 is The locking portion 131 can keep elastically engaged with the rack 220 .

As shown in FIG. 5A , FIG. 7 , and FIG. 8 , the rack 220 is arranged so that when the first connection base 100 and the second connection base 200 swing relative to the rotation axis C1 as the center, the The elastic arm 130 can also swing around the rotation axis C1 , so that the locking portion 131 can move back and forth along an arc-shaped path around the rotation axis C1 . For the convenience of description, when the first connection base 100 and the second connection base 200 rotate relative to each other, the moving path of the locking portion 131 is defined as a displacement path.

As shown in FIGS. 5A and 5B , the rack 220 has a plurality of tooth shapes 223 , and the plurality of tooth shapes 223 of the rack 220 are arranged on the displacement path of the locking portion 131 . Therefore, when the locking portion 131 at the end of the elastic arm 130 is engaged with a plurality of tooth shapes 223 at different angular positions on the rack 220, the first connecting seat 100 and the second The two connecting bases 200 are positioned at a plurality of different relative angular positions. And two ends of the rack 220 respectively form a first stop part 221 and a second stop part 222 . When the elastic arm 130 swings to a position in contact with the first stop part 221 and the second stop part 222 , the elastic arm 130 can contact the first stop part 221 and the second stop part 222 The elastic arm 130 is blocked and cannot continue to swing. Therefore, through the first stop portion 221 and the second stop portion 222, the elastic arm 130 can be restricted from swinging only one time. It swings back and forth within the angular range, and cannot be separated from the rack 220 .

As shown in FIGS. 5A and 5B , the plurality of tooth shapes 223 of the rack 220 of the present invention are configured to be arranged in an arc-shaped path substantially centered on the first rotation axis C1 and with a radius of curvature r on the side wall 215 of the second connection seat 200 , so that the curved arc of the arrangement paths of the tooth shapes 223 of the rack 220 can match the locking portion 131 when the elastic arm 130 swings. The displacement paths are matched, so that the elastic arm 130 swings around the first rotation axis C1, so that when the locking portion 131 is relatively displaced by the rack 220, the locking portion 131 and the The interference degree of each of the tooth shapes 223 on the rack 220 can be kept equal, and a stable engaging and positioning force can be maintained.

In addition, as shown in FIG. 6 , when viewed from the top view of the hinge structure 1 , the tooth profile 223 of the rack 220 is configured to be inclined relative to the side wall 215 , so that the tooth profile of the rack 220 and all The longitudinal axis direction C2 has an included angle θ, and the included angle θ between the tooth profile 223 of the rack 220 and the longitudinal axis direction C2 is configured to be between 15 degrees and 45 degrees.

By arranging the plurality of tooth profiles 223 of the rack 220 relative to the longitudinal axis direction C2, the locking portion 131 at the end of the elastic arm 130 acts on the stress on the rack 220 The direction can have an oblique angle with the longitudinal axis direction C2, so that the acting direction of the stress acting on the rack 220 by the elastic arm 130 is changed. Therefore, the locking portion 131 at the end of the elastic arm 130 can exert sufficient pressure on the rack 220 to maintain a stable positioning effect. When the connecting seat 200 is relatively swung and the locking portion 131 and the rack 220 are relatively displaced, the teeth 223 of the locking portion 131 and the rack 220 are not easily worn.

As shown in FIGS. 7 and 8 , through the hinge structure 1 , the angle between the temple 400 of the glasses 2 and the glasses body 300 can be adjusted. In this embodiment, in the hinge structure 1, the rotation axis C1 of the first connection base 100 and the second connection base 200 is arranged to be parallel to a horizontal direction of the glasses body 300, so that the The temple 400 can relatively rotate around the rotation axis C1 between the first connection base 100 and the second connection base 200 , and can pass through the locking portion 131 of the elastic arm 130 and the The rack 220 cooperates to locate the relative rotation angle of the temple 400 and the glasses body 300 .
