no. 1 Embodiment approach

[0077] figure 1 It is an external view showing eyeglasses provided with the rotation structure of this embodiment.

[0078] in addition, figure 2 (A) and figure 2 (B) is an enlarged view explaining the rotation structure of this embodiment.

[0079] The rotating structure A of the present embodiment is composed of a first base member 1 (bracket) mounted on the lens portion of the glasses, and a second base member 2 (foot wire) that abuts against the head side of the user of the glasses and provides a fastening force there. ), and a cylindrical column member 3, the periphery of the column member 3 arranged in parallel with the first base member 1 and the second base member 2 is fixed to the end face of the first base member 1 and the end face of the second base member 2.

[0080] The column member 3 is a member having elasticity due to torsion.

[0081] In addition, for the convenience of description, the fixed part is represented by a dot here.

[0082] That is, if fi...

no. 2 Embodiment approach

[0103] In the rotating structure A of this embodiment, as Figure 6 As shown, the first fixing portion 4 on the end face of the first base member 1 is formed in multiples (two in the drawings), and the second fixing portion 5 on the end face of the second base member 2 is formed on two first fixing portions. between departments.

[0104] In this way, by forming a plurality of first fixing parts 4 and forming the second fixing parts 5 therebetween, the strength of the rotating structure A is improved.

[0105] As a result, even if the second base member 2 is repeatedly rotated, for example, a gap is less likely to be generated between the column member 3 and the first base member 1 , and rotational rattling is less likely to occur.

[0106] In addition, since the distance between the first fixing part and the second fixing part becomes smaller, the elastic force caused by the torsion increases.

[0107] Additionally, in this embodiment, if Figure 7 As shown, the upper first...

no. 3 Embodiment approach

[0115] The rotating structure of this embodiment is an example of glasses having a plurality of the above-mentioned rotating structures, for example, a plurality of such as figure 2 , Figure 6 The structure shown is connected by rotating structures.

[0116] Such as Figure 11 As shown, in the rotating structure A0 of this embodiment, by using the first base member 1A in the rotating structure A1 as the second base member 2A in the rotating structure A2 formed adjacent to the rotating structure A1, the present invention can be combined sequentially. Invented rotating structure.

[0117] In the rotating structure A0, each rotating structure rotates respectively.

[0118] That is, the sum of the rotation areas (rotation ranges) of the respective rotation structures is the rotation area of ​​the rotation structure A0.

[0119] As a result, the bending degree of the foot wire as the second base component 2 can be large, and the overall flexibility can be enhanced.

Abstract

[Problem to be Solved] To provide a pivot structure of eyeglasses that is reduced as little as possible in pivotal resistance even for long-term use, and eyeglasses provided with the pivot structure thereof. [Solution] The pivot structure in eyeglasses includes a first base member 1, a second base member 2, and a pillar member 3 interposed between the first base member 1 and the second base member 2, and a twisting action of the pillar member 3 makes the second base member 2 capable of pivoting on the first base member 1. Further, in the pivot structure, the pillar member 3 and the first base member 1 are fixed by a first fixed portion 4, the pillar member 3 and the second base member 2 are fixed by a second fixed portion 5, and a certain distance in the direction of the pillar axis is placed between the first fixed portion 4 and the second fixed portion 5.

Description

technical field [0001] The present invention relates to a rotating structure excellent in spring characteristics and eyeglasses provided with the rotating structure. Background technique [0002] Conventionally, in eyeglasses, various pivot structures using fastening screws are known as pivotal structures for rotatably attaching a leg wire to a frame via a fastening member (for example, refer to Patent Document 1). [0003] However, in this rotating structure using screws, after the glasses are used for a long time, due to reasons such as vibration, the screws will gradually loosen and fall off easily. [0004] In addition, the tightening force of the screw varies greatly due to a very small difference in the amount of screwing in, so the rotation resistance of the left and right legs may be different from each other, or the rotation resistance of the legs of different products may be different from each other. [0005] As a result, the wearing comfort of the glasses is red...
