Description

Technical Field

[0001] This utility model relates to the field of decorative eyewear technology, specifically to a pair of eyewear that is securely worn on the head. Background Technology

[0002] With the increasing popularity of outdoor sports and the growing trend of integrating fashion accessories, headband sunglasses have gained a significant position in the consumer market due to their dual attributes of decoration and practicality. These products typically employ an integrated flexible temple structure, using radial clamping force generated by the curved deformation of the temples to secure the head.

[0003] However, in practical applications, existing technologies suffer from several drawbacks. Because the contact points between the various parts of the glasses and the head are all smooth surfaces, and the linear deformation characteristics of the universally sized curved clamping legs cause pressure to be concentrated on the protruding parts of the temporal bone, while the clamping force in the parietal bone area is insufficient, the main body of the glasses, which is clamped on the front of the head, is prone to slipping and falling off during dynamic applications such as walking or light running. The fixation is not reliable, which affects the user experience. Summary of the Invention

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pair of glasses that are securely worn on the head, which can effectively solve the problem that the existing headband glasses are only held in place on the head by the elastic clamping of the curved clamping legs, and the main body of the glasses is prone to slipping and falling off during dynamic use such as walking or light running.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a pair of glasses that are securely worn on the head, including a frame body and temple assemblies symmetrically hinged to both sides of the frame body. The temple assemblies include:

[0009] The main temple has a memory elasticity and its radius of curvature is adapted to the side contour of the human head. One end of the main temple is hinged to the main body of the frame, and the other end extends freely along its curvature.

[0010] And an elastic clip, one end of which is fixed to the hinge end of the temple, and the other end is a free end. In the closed state, the elastic clip is elastically attached to the outer side of the main temple. After the elastic clip is bent in the opposite direction and deformed, its main body forms an opening at a certain angle between the free end and the temple.

[0011] Furthermore, the width of the side profile of the main temple gradually narrows from the hinged end outwards, and the side profile of the elastic clip matches the side profile of the main temple.

[0012] Furthermore, the elastic clip is made of super-elastic steel sheet, and the elastic clip has a bent portion formed at the free end, with the bending direction of the bent portion away from the temple.

[0013] Furthermore, it also includes a rigid connector that presses and fixes one end of the elastic clip onto the temple of the main lens.

[0014] Furthermore, the connector has a screw post formed on its mating surface, the main temple has a first connecting hole communicating with the screw post, and the elastic clip has a second connecting hole communicating with the screw post.

[0015] Furthermore, the mating surface of the connector is divided into a first contact surface and a second contact surface by a stepped groove. The depth of the stepped groove is the same as the thickness of the elastic clip. The first contact surface is in contact with the outer side of the main temple, and the second contact surface is in contact with the outer side of the elastic clip.

[0016] Furthermore, a recessed positioning groove is formed at the first contact surface, and a positioning protrusion that fits the positioning groove is provided on the main temple.

[0017] Furthermore, a boss is formed in the middle of the outer side of the main temple, following the direction of its length extension, and a hollow area is formed in the middle of the elastic clip to fit the boss with a gap.

[0018] Furthermore, multiple vent holes are formed on the protrusion, extending inward through the main temple.

[0019] Furthermore, the main temple is an injection-molded part made of PC or nylon material.

[0020] Beneficial effects

[0021] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0022] This invention adds an elastic clip to the outside of the curved temple. One end of the elastic clip is fixedly connected to the temple, while the free end utilizes its bendable and deformable material properties to switch between an open and closed state between the elastic clip and the temple. The clamping space formed in the open state allows the user to easily tuck their hair into the clamping space when wearing the glasses on their head, as the temple is lowered. Then, pressing down the elastic clip to the closed state clamps the hair between the elastic clip and the temple. In this way, the elastic clamping of the temple on the head, combined with the elastic clip securing the hair, greatly improves the stability of the glasses when worn on the head, preventing slippage or loosening during light movement.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments. Example

[0032] This utility model provides a stable pair of glasses worn on the head, which is an improvement on existing headband-style sunglasses. Existing headband-style glasses are only held in place by the elastic clamping of the curved temples, which makes the glasses prone to slipping and falling off during dynamic use such as walking or light running. By improving the design of the 20-part structure of the main temples, the user experience when wearing the glasses on the head is improved.

[0033] This invention provides a pair of glasses that are securely worn on the head, as shown in the reference. Figure 1-5 The system includes a frame body 10 and temple assemblies symmetrically hinged to both sides of the frame body 10. It is worth noting that the temple assemblies are the core of the improved design. The frame body 10 has a rounded shape that can form a headband shape with the main temples 20, or the frame body 10 can be a conventional flat frame shape. Both designs, when used with the temple assemblies, ensure a secure fit on the head. Specifically, the main structure of the temple assemblies includes:

[0034] The curved temple 20 with memory elasticity has a radius of curvature that adapts to the side profile of the human head. One end of the temple 20 is hinged to the frame body 10, and the other end extends freely along its curvature. The bendable temple assembly can reduce the volume occupied when the product is folded up or down.

[0035] And the elastic clip 30, preferably made of super-elastic steel sheet with a thickness of 0.4-0.6mm, the main body is treated with a spray coating process. Structurally, one end of the elastic clip 30 is fixed together with the hinge end of the temple, and the other end is a free end. In the closed state, the elastic clip 30 is elastically attached to the outer side of the main temple 20. After the elastic clip 30 is bent in the opposite direction and deformed, its main body forms an opening at a certain angle between the free end and the temple.

[0036] It also includes a rigid connector 40, which is used to press and fix one end of the elastic clip 30 onto the main temple 20 for specific fixation between the two. The connector 40 of this product serves as an auxiliary connecting accessory, primarily aimed at improving the stability of the connection between the elastic clip 30 and the main temple 20. Simultaneously, it simplifies the molding process of both components, thereby reducing product costs. The connector 40 is preferably made of zinc alloy casting, and as an exterior component, its surface is electroplated.

[0037] The elastic clip 30 has a bent portion 31 formed at its free end through a bending process. The bending direction of the bent portion 31 is away from the main temple 20. When the user wants to remove the main body of the glasses from the head, this small bent portion 31 makes it easy for the user to find the free end of the elastic clip 30 and to easily open the elastic clip 30 to the open state with the help of the fingers, thus making it easy for the user to remove the main body of the glasses from the head.

[0038] In this embodiment, the main temple 20 is preferably an injection-molded part made of PC or nylon material, which has good elastic deformation capability. Alternatively, the main temple 20 can also be made of the same elastic steel material as the elastic clip 30, formed by cutting and bending processes. Of course, in order to maintain good wearing comfort, the main temple 20 of this material can be treated with a rubber coating process.

[0039] The improved temple assembly of this design incorporates an elastic clip 30. Utilizing the flexible and deformable material properties of the clip 30, the open and closed states of the clip and the main temple 20 can be switched. In the open state, a clamping space is formed, where the bent state of the elastic clip 30 remains unchanged, i.e., the open state is maintained. This allows the user to easily guide their hair into the clamping space as the main temple 20 is inserted, and then press down on the elastic clip 30 to return it to the closed state, thus clamping the hair between the clip 30 and the main temple 20. In this way, the elastic clamping of the main temple 20 on the head, combined with the secure clamping of the hair by the elastic clip 30, greatly improves the stability of the glasses when worn on the head.

[0040] The following is a description of the preferred implementation method for this solution:

[0041] In order to achieve a larger clamping area for hair, while ensuring that the main temple 20 can be smoothly inserted under the head, the main temple 20 is designed to gradually narrow in width from the hinged end to the outer end, with the outer end being rounded. The side shape of the elastic clip 30 matches the side shape of the main temple 20.

[0042] In the specific design of fixing the elastic clip 30 to the main temple 20 through the connector 40, the connector 40 has at least two screw posts 41 formed on its mating surface. The main temple 20 is provided with a first connecting hole 21 communicating with the screw posts 41, and the elastic clip 30 is provided with a second connecting hole 32 communicating with the screw posts 41. By passing a self-tapping screw through the first connecting hole 21 and the second connecting hole 32 from the inside of the main temple 20 to the screw post 41, the elastic clip 30 is locked and fixed on the main temple 20.

[0043] To ensure the reliability of the connection between the connector 40 and the elastic clip 30 and to improve the appearance, the mating surface of the connector 40 is divided into a first contact surface 43 and a second contact surface 44 by a stepped groove 42. The depth of the stepped groove 42 is the same as the thickness of the elastic clip 30. The first contact surface 43 is in contact with the outer side of the main temple 20, and the second contact surface 44 is in contact with the outer side of the elastic clip 30. The connection is limited and pressed tightly by the stepped groove 42. After the three are connected, the joint line is uniform and beautiful.

[0044] In addition, in order to improve the assembly efficiency of the three components during connection, a recessed positioning groove 45 is formed at the first contact surface 43, and a positioning protrusion 22 is provided on the main temple 20 to fit the positioning groove 45 with a clearance. Preferably, the positioning groove 45 is an elongated groove or a rectangular groove. The connector 40 can achieve precise positioning with the main temple 20 by using the positioning groove 45, which facilitates the subsequent connection and fixation of the self-tapping screw.

[0045] In addition, to enhance the clamping ability of the elastic clip 30 and the main temple 20 in clamping the user's hair, a protrusion 23 is formed in the middle of the outer side of the main temple 20, following its length. A hollow area 33, which fits into the protrusion 23, is formed in the middle of the elastic clip 30. The small, misaligned protrusion 23 effectively improves the clamping effect. Preferably, to provide wearing comfort, multiple ventilation holes penetrating the main temple 20 can be formed on the protrusion 23 to provide breathability to the part of the main temple 20 that contacts the scalp.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
