Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, specifically to an adjustable pair of eyeglasses. Background Technology

[0002] refer to Figure 1 and Figure 2 As shown, this is an existing eyeglass structure, which includes a frame 01, temples 02, hinge part one 03, hinge part two 04, and abutment part 05.

[0003] The frame 01 and temple 02 are rotatably connected by hinge 1 03 and hinge 2 04. When the temple 02 is opened, the front end of the temple 02 abuts against the abutment part 05 and hinge 1 03 to limit the maximum opening angle of the temple 02.

[0004] Since different people may have different head shapes and sizes, people with larger heads may experience inconvenience when wearing glasses because the distance between the two temples is slightly smaller when the glasses are opened.

[0005] To accommodate people with different head sizes, eyeglasses often feature temples with adjustable opening angles. To achieve this, current technologies often improve the temples, such as designing the middle section of the temple to be flexible and bendable. Utility Model Content

[0006] In view of the problems pointed out in the background art, this utility model proposes an adjustable pair of glasses that is different from the prior art, so as to solve the above-mentioned technical problems.

[0007] The technical solution of this utility model is implemented as follows:

[0008] An adjustable pair of glasses includes a frame and temples, which are hinged together. The temples are made of a thin sheet material, and the front end of the temple is flush with or located on the front side of the front side of the frame. The front end of the temple has slots on both sides and the front side that extend through its thickness direction.

[0009] The present invention is further configured such that the slot is provided and located at the middle position in the width direction of the temple.

[0010] The present invention is further configured such that the slot has two slots and is spaced apart at intervals along the width of the temple.

[0011] The present invention is further configured such that a plastic temple sleeve is fitted onto the rear end of the temple.

[0012] The present invention is further configured such that the frame is provided with a hinge part one, the temple is provided with a hinge part two, and the hinge part one and the hinge part two are connected by a pivot.

[0013] The present invention is further configured such that the front end of the temple forms an elastic reinforcing portion that extends forward and bends toward the side of the frame to fit against the front side of the frame.

[0014] The present invention is further provided that the hinge part one is provided with a limiting part on both sides, and the two limiting parts are respectively located on both sides of the temple in the width direction.

[0015] The present invention is further configured such that the temples are made of metal material.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] When the temples are opened, the front ends of the temples abut against the frame and hinge. If the temples need to be opened further, they can be forced to rotate further. At this time, the front ends of the temples undergo elastic bending deformation, allowing the temples to rotate further. When the glasses are not in use, the elastic deformation at the front ends of the temples recovers when the temples are folded.

[0018] The temples are made of thin sheet material and have grooves at the front end, which helps the front end of the temples to bend and deform elastically, and helps to further open the temples to adjust the distance between the two temples. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] For reference as follows Figures 1-11 The present invention will be described as follows:

[0034] Example: An adjustable pair of glasses includes a frame 01 and temples 02, which are hinged together. The frame 01 has a first hinge portion 03, and the temples 02 have a second hinge portion 04. The first hinge portion 03 and the second hinge portion 04 are connected by a pivot. The two hinge portions are rotatably connected by the pivot, providing a basic rotational fulcrum for the opening and closing adjustment of the temples 02.

[0035] The temple 02 is made of a thin sheet material. The thin structure gives the material a certain elastic deformation capability, providing a material basis for the temple 02 to bend elastically during adjustment.

[0036] The front end of the temple 02 is flush with or located on the front side of the front side of the frame 01. This position setting ensures the relative position of the temple 02 and the frame 01 in the initial open / closed state, laying the foundation for the abutment and limit function in the subsequent adjustment process.

[0037] The front end of the temple 02 has slots 6 that extend through its thickness direction on both sides and the front side. This slot design further weakens the local stiffness at the front end, making the front end area more prone to elastic deformation in the entire temple 02 structure, thereby optimizing the mechanical conditions for elastic bending.

[0038] When the temple 02 is opened normally, its front end will abut against the frame 01 and the hinge, at which point the initial opening angle limit is reached.

[0039] If it is necessary to further increase the opening angle, the external force forces the temple 02 to continue to rotate. Due to the elasticity of the material at the front end of the temple 02 and the structural design of the slot 6, the front end will undergo elastic bending deformation. This deformation releases the rotational resistance, allowing the temple 02 to break through the initial limit and achieve further opening, thereby adjusting the distance between the two temples 02.

[0040] When the glasses are not in use and the folded temples 02 are removed, the external force is removed, and the elastic deformation at the front end naturally recovers due to the elastic properties of the material, and the temples 02 return to their initial folded state.

[0041] The thin sheet material of the temple 02 and the design of the front groove 6 form a technological synergy. The thin material provides an overall elastic foundation, while the groove 6 further reduces the deformation resistance at the front end through local structural optimization. The two work together to enable the front end of the temple 02 to bend elastically more efficiently under force, ensuring the smoothness and repeatability of the adjustment process.

[0042] Adaptive adjustment mechanism: The angle is adjusted by elastic deformation, so that the glasses can adapt to the head size of different wearers and improve wearing comfort and applicability.

[0043] Simplified structure combined with functionality: No complex mechanical adjustment parts are required. Adjustable function is achieved only through material selection and structural design, which reduces manufacturing complexity and cost while ensuring the reliability of the adjustment mechanism.

[0044] Reversible deformation characteristics: The elastic deformation of a material occurs when it is subjected to force and recovers after the external force is removed. This reversibility ensures the long-term stability of the adjustment function and avoids structural failure due to repeated adjustments.

[0045] At least one slot 6 shall be provided. The number of slots 6 in this application is provided in the following two implementation structures:

[0046] Implementation Structure 1: A slot 6 is provided and located in the middle of the width direction of the temple 02.

[0047] Implementation Structure Two: The slot 6 has two slots, which are spaced apart at a distance of 02 widths from the temple.

[0048] The front end of the temple 02 forms an elastic reinforcing part 8 that extends forward and bends toward the side of the frame 01 to fit against the front side of the frame 01.

[0049] When the temple 02 rotates open, the elastic reinforcement 8 rotates synchronously with the front end of the temple 02. When the rotation angle reaches the initial limit point, the bent end of the elastic reinforcement 8 completely abuts against the front side of the frame 01, forming a physical limit. If an external force is applied to force the temple 02 to open further, the elastic reinforcement 8 and the front end of the temple 02 will share the deformation stress and enter the elastic deformation stage.

[0050] The bending structure of the elastic reinforcement 8 gives it independent elastic deformation capability. When the temple 02 is over-opened, this component and the slotted structure at the front end of the temple 02 deform in tandem: the slotted structure reduces the overall stiffness of the front end, while the elastic reinforcement 8 absorbs part of the external force through the elastic deformation of its own bending structure, reducing the deformation of the temple body material.

[0051] The presence of the elastic reinforcement 8 disperses the deformation stress from a single area at the front end of the temple 02 to the joint area between the reinforcement and the front body, avoiding material fatigue damage caused by stress concentration at the edge of the slot 6 and extending the service life of the temple structure.

[0052] The hinge portion 03 has two limiting portions 7 on each side, located on opposite sides of the temple 02 in the width direction. These limiting portions 7 restrict the front end of the temple 02 in the width direction, preventing deformation of the temple 02 in that direction.

[0053] The limiting part 7 and the hinge part 103 are integrated into one design, or fixed to both sides of the hinge part by welding process to ensure the stability of the limiting function.

[0054] When the temple 02 is subjected to lateral force during opening and closing, or when it tends to deform in the width direction due to asymmetrical adjustment, the inner surface of the limiting part 7 forms a physical abutment with the two front edges of the temple 02. This abutment relationship forms a rigid constraint in the width direction of the temple 02, preventing it from undergoing lateral bending or torsional deformation.

[0055] The constraint of the limiting part 7 in the width direction ensures that the deformation of the elastic reinforcement part 8 only occurs in the length direction (i.e., the opening and closing direction of the temple), thus avoiding the dispersion of the restoring force of the elastic reinforcement part 8 due to deformation in the width direction and ensuring the effectiveness of its restoring ability.

[0056] The temple 02 is made of metal. A plastic temple sleeve is attached to the rear end of the temple 02.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
