Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to a folding eyeglass temple. Background Technology

[0002] The temples are a very important part of the eyeglass frame. They are mainly used to rest against the user's ears when wearing the glasses, and together with the nose pads, they rest against the user's nose bridge to ensure a stable fit.

[0003] Nowadays, with the continuous changes in user needs, the types of eyeglass temples are becoming more and more diverse. Folding eyeglass temples are one of the more common types. For example, a folding eyeglass frame disclosed in Chinese Patent (Authorization Announcement No.: CN217846800U) includes a frame, a left temple, and a right temple. The frame includes a left frame and a right frame that can be folded relative to each other. The right temple includes a right front half and a right rear half that can be folded relative to each other, and the left temple includes a left front half and a left rear half that can be folded relative to each other. The right front half and the left front half are both hinged to a hinge seat. The hinge seat is connected to the frame through a rotating structure. The right temple rotates around the right frame and is placed outside the right frame through the hinge seat. The left temple rotates around the left frame and is placed outside the left frame through the hinge seat.

[0004] Based on claim 1 of the prior art, in conjunction with the appended... Figure 1 , 2 It is known that both temples disclosed consist of a front temple and a back temple. Although the text does not specify how the front temple and the back temple are connected to achieve relative folding, it can be seen from the attached diagram that they are connected by a pin.

[0005] The eyeglasses structure disclosed in the prior art is mainly designed to reduce the size when folded up, so as to make them convenient to carry when going out. However, in actual use, especially the two temples, the front and back temples cannot form a good positioning. This causes the back temple to rotate around the hinge relative to the front temple when folded up, and similarly, the back temple may flip and close relative to the front temple when worn, resulting in poor stability. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a folding temple design for eyeglasses. The technical problem this invention aims to solve is: how to improve the structural stability of the eyeglass temples while ensuring they can be folded.

[0007] The objective of this utility model can be achieved through the following technical solution: a folding temple for eyeglasses, comprising a long strip-shaped connecting segment and a folding segment, wherein the front end of the connecting segment and the rear end of the folding segment are hinged together, characterized in that a positioning member is provided at the rear end of the connecting segment, the positioning member is slidably connected to the connecting segment along the length direction of the connecting segment, and an elastic member is also provided at the rear end of the connecting segment, the elastic member elastically acting between the positioning member and the rear end of the connecting segment along the length direction of the connecting segment, and the positioning member and the front end of the folding segment are pressed together.

[0008] This folding temple design comprises a connecting section and a folding section. In existing technology, the front end of the connecting section is hinged to the eyeglass frame. Furthermore, the front end of the folding section and the rear end of the connecting section are hinged together. Through their rotatable connection, the temple can be folded or unfolded. Importantly, this application adds an elastic element and a positioning element between the rear end of the connecting section and the front end of the folding section, based on the aforementioned hinged structure. In the assembled state, the positioning element can slide along the length of the connecting section. The elastic element ensures that the positioning element remains pressed against the outer wall of the front end of the folding section under its elastic force. This pressing force creates sufficient preload in the circumferential direction between the connecting section and the folding section, preventing the folding section from rotating relative to the connecting section during wearing and storage. This ensures the structural stability of the temple while maintaining its folding and unfolding function.

[0009] In the aforementioned folding temple design, a slot is provided at the rear end of the connecting section along its length. The elastic element is a spring inserted into the slot, with its inner end abutting against the bottom wall of the slot. The positioning element is a pin, with one end inserted into the slot and abutting against the outer end of the elastic element, and the other end abutting against the front end of the folding section. Specifically, the slot at the rear end of the connecting section accommodates the elastic element and the positioning element. Simultaneously, the slot wall guides the deformation direction of the elastic element and the force direction of the positioning element, ensuring a more sufficient clamping force acting on the front end of the connecting section, thus guaranteeing the structural stability of the temple. Alternatively, a screw can be used for the positioning element, and a rubber block with high elastic deformation can be used for the elastic element.

[0010] In the aforementioned folding temple design, a radially shaped groove is formed at one end where the positioning member and the folding section abut. The front end of the folding section has a circular plate-shaped hinge portion. The folding section is hinged to the connecting section via the hinge portion. The outer peripheral wall of the hinge portion has several locking teeth, which are spaced apart circumferentially along the hinge portion. One of the locking teeth is embedded in the groove. As a further specific embodiment, by creating a groove on the positioning member and forming a circular plate-shaped hinge portion at the front end of the folding section, the locking teeth on the outer wall of the hinge portion cooperate with the groove to achieve greater damping when the folding section rotates, effectively ensuring the structural stability of the temple.

[0011] In the aforementioned folding temple, the cross-sectional profile of the groove wall along the axial direction of the positioning member is arc-shaped, and the edge of the groove wall and the outer end face of the positioning member form an arc transition. Similarly, the cross-sectional profile of each locking tooth along the axial direction of the folding section is arc-shaped, and there is an arc transition between every two adjacent locking teeth. Specifically, when the folding section rotates around the hinge, the spring, acting as an elastic element, is pushed by each locking tooth, causing the positioning member to slide back and forth along the axial direction of the connecting section. During this process, there is strong friction between each locking tooth and the groove, especially in the hinge section, which is actually made of the same material as the folding section. Therefore, continuous long-term use will inevitably cause rapid wear of the hinge section. This application addresses this by adaptively adjusting the profiles of both, thereby reducing frictional interference and effectively improving the service life of the temple.

[0012] In the aforementioned folding temple design, the rear end of the connecting section has a hinge interface extending laterally. This hinge interface communicates with the slot and penetrates the inner wall of the rear end of the connecting section. The hinge portion is hinged within the hinge interface, and the outer end of the positioning member extends into the hinge interface. This design allows the connecting section and the folding section to be hinged together via a hinge shaft, ensuring the hinge portion is firmly confined within the hinge interface. Under this premise, it ensures that the locking teeth outside the hinge portion can fully engage with the slotted groove at the outer end of the positioning member, thereby improving the overall structural stability of the temple.

[0013] In the aforementioned folding temple design, the hinge and the front end of the folding section are integrally formed. This ensures the overall structural stability of the folding section.

[0014] Compared with existing technologies, this folding temple design has the following advantages:

[0015] 1. By setting a positioning element at the rear end of the connecting section and an elastic element that acts elastically on the positioning element along the axial direction of the connecting section, the positioning element can be pressed against the front end of the folding section, ensuring sufficient pre-tightening force between the connecting section and the folding section, thereby improving structural stability while ensuring that the temples of the glasses still have the folding function.

[0016] 2. The positioning component and the hinge are engaged by a slot and locking teeth, which further improves the damping force between the connecting section and the folding section, thereby ensuring the structural stability of the temple. Attached Figure Description

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-4 As shown, this folding temple of the glasses includes a long strip-shaped connecting section 1 and a folding section 2. The front end of the connecting section 1 is used to hinge with the eyeglass frame. The rear end of the connecting section 1 has a hinge interface 14, which is arranged horizontally through the inner side wall of the rear end of the connecting section 1. Furthermore, a slot 13 is also provided axially at the rear end of the connecting section 1, and the slot 13 extends through the inner wall of the hinge interface 14. A disc-shaped hinge part 21 is formed at the front end of the folding section 2. The hinge part 21 is arranged horizontally and extends into the hinge interface 14. The rear end of the connecting section 1 is hinged to the hinge part 21 by a hinge shaft, so that the folding section 2 can rotate relative to the connecting section 1.

[0025] An elastic element 12 and a positioning element 11 are respectively provided at the rear end of the connecting section 1, combined with Figure 5The elastic element 12 is specifically a spring, and the positioning element 11 is a pin. The elastic element 12 is inserted into the slot 13 and its inner end abuts against the bottom wall of the slot 13. The front end of the pin has abutting edge along the circumferential direction. The front end of the pin is inserted into the slot 13 and abuts against the outer end of the elastic element 12 through the abutting edge. The rear end of the pin extends into the hinge interface 14 and abuts against the outer wall of the hinge part 21. As an alternative, the elastic element 12 can also be a rubber block with a high elastic coefficient, and the positioning element 11 can also be a screw. When rubber is used as the elastic element 12, it is necessary to ensure that the outer diameter of the rubber block is smaller than that of the slot 13 to ensure that the rubber block has sufficient space in the slot 13 for deformation under pressure.

[0026] like Figure 2 and Figure 5 As shown, a strip groove 111 is radially formed at the rear end of the positioning member 11, and both ends of the strip groove 111 extend to the side wall edge of the positioning member 11. Furthermore, a plurality of locking teeth 211 are formed on the outer wall of the hinge portion 21, and these locking teeth 211 are spaced apart along the outer peripheral wall of the hinge portion 21. Any one of the locking teeth 211 is embedded and positioned within the strip groove 111. It is also worth mentioning that the cross-sectional profile of the groove wall of the strip groove 111, when cut along the axial direction of the positioning member 11, is arc-shaped, and the edge of the groove wall of the strip groove 111 and the outer end face of the positioning member 11 form an arc-shaped transition. Additionally, the cross-sectional profile of each locking tooth 211, when cut along the axial direction of the folded section 2, is arc-shaped, and there is an arc-shaped transition between every two adjacent locking teeth 211.

[0027] Operating principle: The user manually pushes the folding section 2 inward or outward relative to the connecting section 1. During this process, the positioning member 11 always has the tendency to slide outward along the axis of the connecting section 1 under the elastic action of the elastic member 12, so that the outer end of the positioning member 11 and the outer wall of the hinge part 21 are pressed together, and one of the locking teeth 211 on the outside of the hinge part 21 is embedded and positioned in the strip groove 111. Under the elastic action of the elastic member 12, the positioning member 11 and the hinge part 21 cooperate to achieve the purpose of damping the connecting section 1 and the folding section 2 in the circumferential direction, ensuring the stability of the temples in the folded and unfolded states.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0029] Although this document frequently uses terms such as connecting segment 1, positioning element 11, strip groove 111, elastic element 12, slot 13, hinge interface 14, folding segment 2, hinge part 21, and locking tooth 211, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
