Description

Technical Field

[0001] The invention relates to glasses, in particular to glasses with an elastic limiting structure. Background Art

[0002] The connection between the temples and the frames of glasses can be divided into two types: elastic hinges and inelastic hinges, depending on whether they have elasticity. Elastic hinges can be divided into integrated structures and split structures, for example:

[0003] The integrated structure solution refers to the internal card-type eyeglass frame slingshot disclosed in the utility model patent in the prior art (CN217787528U). The prior art requires purchasing a finished slingshot or assembling the slingshot by oneself, and then installing the assembled slingshot on the temple. However, the slingshot structure is relatively complex and has a high cost problem.

[0004] The split structure solution refers to the eyeglass slingshot (CN216118259U) disclosed in the utility model patent in the prior art that can be installed by laser welding as a whole. The spring part of the prior art is a separate structure. When installing, the spring needs to be filled into the groove of the temple by yourself, and then the hinge part is installed on the temple and fixed by screws, etc. This structure is more complicated in the installation steps, which will reduce the installation efficiency.

[0005] In combination with the above-mentioned prior art, it can be seen that the glasses with elastic hinges still have the problems of low installation efficiency or high cost. Summary of the invention

[0006] In view of the deficiencies in the prior art, an object of the present invention is to provide a pair of glasses with an elastic limiting structure, which has the characteristics of high installation efficiency, low cost and simple structure.

[0008] As a further improvement of the present invention, a positioning groove for placing an elastic member is provided at the bottom of the slot, and the elastic member is located in the positioning groove and at least a portion thereof extends out of the positioning groove and abuts against the connecting member to cooperate with the first groove and the second groove on the connecting member to limit the temple.

[0009] As a further improvement of the present invention, an arc-shaped transition is provided between the groove wall on the other side of the slot corresponding to the notch and the positioning groove.

[0010] As a further improvement of the present invention, the position between the first groove and the second groove on the connecting member is set as an arc-shaped transition.

[0011] As a further improvement of the present invention, the connecting piece and the temple are integrally formed.

[0012] As a further improvement of the present invention, the first groove and the second groove are arc-shaped grooves.

[0013] As a further improvement of the present invention, the elastic member is in a hollow cylindrical shape and has radial elastic force, and the outer peripheral surface of the elastic member cooperates with the first groove and the second groove.

[0014] As a further improvement of the present invention, the connecting member is provided with a through hole in the longitudinal direction, and the through hole is used to cooperate with the screw to rotatably connect with the frame, and the connecting member rotates with the screw as a rotation axis.

[0025] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0026] A pair of glasses with an elastic limiting structure, comprising a frame 2, and temples 1 mounted on the frame 2, the temples being rotatably connected to the frame 2, a connecting piece 3 being provided on the temples 1, and forming a rotatable connection with the frame 2 through the connecting piece 3, a slot 21 being provided at a position on the frame 2 corresponding to the connecting piece 3, and a notch 22 for the connecting piece 3 to rotate in and out is provided at a side of the slot 21, the connecting piece 3 being located in the slot 21 and forming a rotatable connection with the frame 2; an elastic piece 4 being provided in the slot 21, and a first groove 31 and a second groove 32 are respectively provided on the connecting piece 3 corresponding to the positions where the temple 1 is opened and retracted, the elastic piece 4 abuts against the connecting piece 3, and when the temple 1 is opened and retracted, the elastic piece 4 is embedded in the first groove 31 or the second groove 32 to limit the rotation of the temple 1.

[0027] In this solution, the frame 2 and the temple 1 are installed by the connection member 3 cooperating with the slot 21. The connection member 3 of the temple 1 is inserted into the slot 21 and is rotatably connected in the slot 21. A notch 22 is provided for the rotation position of the temple 1 when it is opened and closed, so that the connection member 3 can be moved in and out when it is rotated. The elastic member 4 in the slot 21 can be filled into the slot 21, and the connection member 3 is inserted into the slot 21. The connection member 3 has a first groove 31 and a second groove 32, which respectively correspond to the two states of the temple 1 being opened and closed. When the corresponding first groove 31 or second groove 32 corresponds to the position of the elastic member 4, the elastic member 4 is embedded in the first groove 31 or the second groove 32. The opening and closing actions of the temple 1 are limited by the elastic member 4 cooperating with the first groove 31 or the second groove 32. The temple 1 will be out of the current state only when the force applied to the temple 1 is sufficient to deform the elastic member 4 and escape from the first groove 31 or the second groove 32. The elastic limit effect can replace the traditional slingshot structure, simplify the installation cost and improve the installation efficiency. However, it cannot replace the slingshot structure that opens when the hand is released, that is, the slingshot structure in which the temple 1 in the closed state automatically opens outward under the action of elastic force without being blocked by external force.

[0028] When the above solution is used, the elastic member 4 is initially embedded in the second groove 32 corresponding to the temple 1 being folded into place, and the temple 1 is limited to open by the elastic force and the cooperation of the second groove 32. When the temple 1 is opened by a sufficient force, the connecting member 3 will rotate with the temple 1 and force the elastic member 4 to deform (at this time, the elastic member 4 is separated from the second groove 32, and a sense of resistance reduction will be generated). When the temple 1 is about to open into place, the edge of the first groove 31 corresponding to the opening into place on the connecting member 3 begins to contact the elastic member 4. At this time, the elastic member 4 begins to recover and bounce up under the action of the elastic force, and cooperates with the first groove 31 to produce a bouncing action, providing a bouncing feedback. Similarly, when the temple 1 is folded into place, a bouncing feedback will also be generated.

[0029] The connecting member 3 is longitudinally provided with a through hole, and the through hole is used to match the screw and the frame 2 for rotatable connection, and the connecting member 3 rotates with the screw as the rotating shaft. In this arrangement, the temple 1 can be assembled by simply installing the connecting member 3 with the frame 2 through the screw, and it also has a rotating function, so that the first groove 31 and the second groove 32 on the connecting member 3 can form a stable match with the elastic member 4, and the elastic member 4 is kept in the frame 2 and will not fall out.

[0030] The solution of the slot 21 can provide a certain limiting effect on the elastic member 4, making it easier to install the elastic member 4. The size of the notch 22 can be smaller than the elastic member 4, in which case the elastic member 4 is not easy to fall out of the notch 22 during the installation process. Of course, the size can also be larger than the elastic member 4, for example, the entire groove wall on one side of the slot 21 is open.

[0031] In a further configuration, for the convenience of installation, a positioning groove 23 for placing the elastic member 4 is provided at the bottom of the slot 21. The elastic member 4 is located in the positioning groove 23 and at least a portion thereof extends out of the positioning groove 23 and abuts against the connecting member 3, so as to cooperate with the first groove 31 and the second groove 32 on the connecting member 3 to limit the temple 1. During installation, the elastic member 4 only needs to be filled into the positioning groove 23 to make the elastic member 4 in a relatively stable state, and then the first groove 31 of the connecting member 3 is pressed against the elastic member 4 at the position of the temple 1 corresponding to the open state, so that the elastic member 4 can be in a stable state and will not be ejected and lost under the action of elastic force, and the installation is more convenient. Then, the through hole on the connecting member 3 is aligned with the through hole on the frame 2, and the installation is completed by screws to complete the installation of the temple 1, the elastic member 4, and the frame 2. The size of the positioning groove 23 can preferably be a size that matches the elastic member 4, so that its state is further stabilized.

[0032] In addition, an arc-shaped transition is provided between the groove wall on the other side of the slot 21 corresponding to the notch 22 and the positioning groove 23. The arc-shaped transition can make installation more convenient, and the elastic member 4 can slide into the positioning groove 23 by means of the groove wall of the slot 21 cooperating with the arc-shaped transition. In fact, the arc-shaped transition can also cooperate with the connecting member 3, so that the rotation of the connecting member 3 will not be blocked.

[0033] In order to make the connection member 3 cooperate more smoothly with the elastic member 4 during the rotation process, the position between the first groove 31 and the second groove 32 on the connection member 3 is set as an arc transition.

[0034] After the elastic member 4 leaves the first groove 31 or the second groove 32 , it will slide relative to the surface of the connecting member 3 . The arc-shaped transition can make the sliding process smoother and the hand feel more stable without generating an extra segment hand feel.

[0035] Since the above solution does not assemble the elastic limiting structure in the temple 1, in order to reduce the cost and improve the production efficiency, in the preferred solution, the connecting member 3 and the temple 1 are integrally formed.

[0036] In addition, as a further setting to improve the experience, the first groove 31 and the second groove 32 are arc-shaped grooves. The cooperation between the arc-shaped structure and the elastic member 4 can produce a more continuous effect, and at the same time, a better hand feel can be maintained during the process of opening and closing the temple 1.

[0037] Especially in the scheme where the elastic member 4 is hollow and cylindrical and has radial elastic force, and the outer peripheral surface of the elastic member 4 cooperates with the first groove 31 and the second groove 32. The surface of the cylindrical structure and the arc-shaped first groove 31 and the second groove 32 can form a more continuous transition, and there will be no problems such as jamming. Moreover, the cylindrical structure can cooperate with the arc-shaped surfaces of the first groove 31 and the second groove 32, and has a guiding effect, so that the temples have a smoother and more stable springing effect when they are about to be opened or retracted, and the elastic feel generated is more stable and obvious.

[0038] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
