Description

Technical Field

[0001] The utility model belongs to the technical field of glasses, in particular to a glasses frame without nose pads. Background Art

[0002] Nose padless glasses frames abandon the traditional nose pad structure and adopt other supporting structures that can replace the nose pad to achieve the same or better stability effect. They aim to provide users with a more fitting, comfortable and stable wearing experience.

DETAILED DESCRIPTION

[0044] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-8 :

[0045] Example 1:

[0046] This embodiment provides a nose pad-free glasses frame, comprising glasses legs 1 and a lens frame 2, wherein the front ends of the glasses legs 1 are rotatably connected to the two ends of the lens frame 2, and is characterized in that it further comprises:

[0047] The bending assembly 3 includes a bending body 31 provided at the rear end of the temple 1 and a soft cushion layer 32 provided inside the bending body 31. The bending body 31 is arranged around the outer ear contour;

[0048] The support assembly includes a first support member 4 and a second support member 5. One end of the first support member 4 is connected to the temple 1 and the other end is in contact with the cheekbone. One end of the second support member 5 is connected to the temple 1 and the other end is in contact with the skin above the outer ear.

[0049] A first sliding assembly 6 is provided between the first support member 4 and the glasses leg 1;

[0050] A second sliding assembly 7 is provided between the second support member 5 and the glasses leg 1;

[0051] The first support member 4 is designed as a double-layer composite structure 9 .

[0052] Nose pad glasses frames refer to glasses frames that do not rely on traditional nose pads for support, but are fixed to the user's face by other means.

[0053] The bending assembly 3 includes a bending body 31 and a soft cushion layer 32, which are used to fit and wrap around the user's outer ear contour to provide additional stability and comfort. The bending body 31, as the hard part of the bending assembly 3, is responsible for supporting and fixing the soft cushion layer 32. The bending body 31 can be an arc-shaped structure that fits the outer ear contour. The bending body 31 is located above the soft cushion layer 32 and can be made into an integral part with the glasses leg 1. The soft cushion layer 32 can be fixed to the bottom of the bending body 31 by other means such as bonding or sewing. The soft cushion layer 32 can be made of materials such as memory foam, silicone or TPU thermoplastic polyurethane to increase wearing comfort and reduce the feeling of oppression.

[0054] The support assembly includes a first support member 4 and a second support member 5, providing additional support points beyond the bending member 3, reducing the burden on the bridge of the nose and ears. The curved design of the first support member 4, which conforms to the cheekbones, ensures stable support for the frame when worn. This design evenly distributes the weight of the frame, reducing the tendency of the glasses to slide due to gravity, thereby improving wearing comfort.

[0055] The first sliding assembly and the second sliding assembly 7 allow the support member to slide on the glasses leg 1 to adjust its position to adapt to the facial features of different users.

[0056] A double-layer composite structure9 refers to a structure made of two different materials stacked together, often used to enhance the durability, comfort or functionality of a component.

[0057] Example 2:

[0058] This embodiment provides a nose pad-free glasses frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] The first sliding assembly 6 includes:

[0060] A first slider 61 is provided in the temple 1, and a first sliding groove 65 for sliding the first slider 61 is provided on the lower surface of the temple 1;

[0061] First limiting holes 62 are arranged on the first slider 61 at equal intervals, and internal threads are provided in the first limiting holes 62;

[0062] The first limiting rod 63 matches the first limiting hole 62, and the bottom of the first limiting rod 63 is provided with an external thread that matches the internal thread of the first limiting hole 62;

[0063] The outer side of the glasses leg 1 is provided with a first positioning hole 64 matching the first limiting hole 62 , and the first limiting rod 63 is connected to the first limiting hole 62 through the first positioning hole 64 .

[0064] The first slider 61, a core component of the first sliding assembly, allows for relative sliding adjustment between the temple 1 and the first support member 4 to accommodate different facial contours and wearing comfort. The first slider 61 is typically a smooth, T-shaped block built into the temple 1. A first chute 65 provides guidance and positioning for the first slider 61, ensuring a smooth sliding motion and preventing it from dislodging from the temple 1. The first chute 65 is typically designed as a groove that matches the first slider 61 and is of sufficient length to allow for adequate sliding range. The first chute 65 is located on the lower surface of the front end of the temple 1, facilitating user adjustment of the position of the first support member 4 through external manipulation.

[0065] The first limiting hole 62 and the first limiting rod 63 are threadedly matched to fix the first slider 61 in a specific position, preventing accidental movement during the sliding process and ensuring wearing stability. The first limiting holes 62 are small holes with internal threads, which are evenly distributed on the first slider 61. The first limiting rod 63 has external threads that match these internal threads. The first limiting rod 63 is connected to the first limiting hole 62 through the first positioning hole 64 on the outside of the eyeglass leg 1 to achieve fixation. The first positioning hole 64 serves as a channel for the first limiting rod 63 to enter the interior of the eyeglass leg 1 and cooperates with the first limiting hole 62 to achieve the fixing function. The first positioning hole 64 is located on the outside of the eyeglass leg 1 and can correspond to the position of one of the first limiting holes 62 near the middle.

[0066] Example 3:

[0067] This embodiment provides a nose pad-free glasses frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] The first supporting member 4 is an arc-shaped pad 8 that fits the cheekbone, and the arc-shaped pad 8 is a hollow ring structure;

[0069] The top of the arc-shaped pad 8 is fixed to the first sliding block 61 .

[0070] The main function of the curved pad 8 is to fit the user's cheekbones, provide stable support, reduce the dependence of the glasses frame on the bridge of the nose, and increase wearing comfort and stability. The curved pad 8 has a hollow ring structure. This design not only reduces weight and saves material costs, but also enhances breathability and wearing comfort. The curved pad 8 can be designed according to ergonomics to match the contours of the cheekbones, ensuring a close fit and evenly distributed pressure. The curved pad 8 is located between the temple 1 and the cheekbone. As one of the main contact points between the glasses frame and the face, the upper end of the curved pad 8 can be fixed to the first slider 61 by bolts or adhesives.

[0071] Example 4:

[0072] The arc pad 8 is designed as a double-layer composite structure 9, including:

[0073] The hard support layer 91 is made of polycarbonate and is provided on one side close to the outer side of the glasses leg 1;

[0074] The soft buffer layer 92 is made of TPU thermoplastic polyurethane and is disposed between the hard support layer 91 and the user's face. A plurality of anti-slip bumps 10 are disposed on the inner side of the soft buffer layer 92 .

[0075] This embodiment provides a nose pad-free glasses frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] The dual-layer composite structure 9 achieves enhanced support, comfort, and durability by combining layers of different materials. The dual-layer composite structure 9 consists of two different layers: an outer, hard support layer 91 located near the outer side of the temple 1 to provide support, and an inner, soft, cushioning layer 92 located against the wearer's face to provide cushioning. The two layers are tightly bonded together by adhesive, heat-seal, or other means to form a single, integrated structure.

[0077] The hard support layer 91 is made of polycarbonate, which is suitable as a support structure material due to its excellent mechanical properties and impact resistance. At the same time, it ensures that the first support member 4 has sufficient hardness and stability to support the weight of the glasses and disperse the pressure.

[0078] The soft cushioning layer 92 is made of TPU thermoplastic polyurethane (TPU). Due to its excellent elasticity and wear resistance, TPU is suitable for contact with the face. It also provides a soft and comfortable touch, effectively relieving pressure and enhancing wearing comfort. The soft cushioning layer 92 also features several anti-slip bumps 10 evenly distributed on the side closest to the face to increase friction with the face, prevent the glasses from slipping, and further enhance the stability of the first support member 4.

[0079] Example 5:

[0080] This embodiment provides a nose pad-free glasses frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0081] The second sliding assembly 7 includes:

[0082] A second slider 71 is provided in the temple 1, and a second sliding groove 75 is provided on the inner side of the temple 1 for the second slider 71 to slide;

[0083] Second limiting holes 72 are arranged on the second slider 71 at equal intervals, and internal threads are provided in the second limiting holes 72;

[0084] The second limiting rod 73 matches the second limiting hole 72, and the bottom of the second limiting rod 73 is provided with an external thread that matches the internal thread of the second limiting hole 72;

[0085] A second positioning hole 74 matching the second limiting hole 72 is provided on the outer side of the glasses leg 1 , and the second limiting rod 73 is connected to the second limiting hole 72 via the second positioning hole 74 .

[0086] The second slider 71, the core component of the second sliding assembly 7, allows for relative sliding adjustment between the temple 1 and the second support member 5 to accommodate different facial contours and wearer comfort. The second slider 71 is typically a smooth, T-shaped block built into the temple 1. A second chute 75 guides and limits the second slider 71, ensuring a smooth sliding motion and preventing it from dislodging from the temple 1. The second chute 75 is typically designed as a groove that matches the second slider 71 and is of sufficient length to allow for adequate sliding range. The second chute 75 is located on the lower surface of the front end of the temple 1, facilitating user adjustment of the second support member 5 through external manipulation.

[0087] The second limiting hole 72 and the second limiting rod 73 are threadedly matched to fix the second slider 71 in a specific position, preventing accidental movement during the sliding process and ensuring wearing stability. The second limiting holes 72 are small holes with internal threads, which are evenly distributed on the second slider 71. The second limiting rod 73 has external threads that match these internal threads. The second limiting rod 73 is connected to the second limiting hole 72 through the second positioning hole 74 on the outside of the eyeglass leg 1 to achieve fixation. The second positioning hole 74 serves as a channel for the second limiting rod 73 to enter the interior of the eyeglass leg 1 and cooperates with the second limiting hole 72 to achieve the fixing function. The second positioning hole 74 is located on the outside of the eyeglass leg 1 and can correspond to the position of two of the second limiting holes 72 near the middle.

[0088] Example 6:

[0089] This embodiment provides a nose pad-free glasses frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0090] The second support member 5 includes:

[0091] The suction cup 51 has a groove on its inner side, and the groove and the user's face form a chamber. The suction cup 51 also has a number of anti-slip bumps 10 on its inner side.

[0092] One end of the connecting rod 52 is connected to the second slider 71 , and the other end is connected to the outer side of the suction cup 51 .

[0093] The suction cup 51, as the main component of the second support member 5, adheres tightly to the skin above the outer ear through suction, providing additional support and stability, preventing the glasses from slipping, enhancing wearability, and improving the user's wearing experience. The suction cup 51 has a groove inside, forming a chamber with the user's face, creating a negative pressure environment to achieve the suction effect. Furthermore, the side of the suction cup 51 closest to the face is equipped with anti-slip bumps 10 to increase friction. The suction cup 51 is typically circular or oval in shape to conform to the contour of the upper outer ear.

[0094] The connecting rod 52 serves as a connecting component between the suction cup 51 and the temple 1, transmitting the movement of the second slider 71 to the suction cup 51 while maintaining a stable position of the suction cup 51, ensuring that the suction cup 51 can move with the movement of the second slider 71 while maintaining a close fit with the skin. The connecting rod 52 is typically a slender rod-shaped structure, one end of which can be connected to the second slider 71 by screws or welding, and the other end can be connected to the outside of the suction cup 51 by plugging or snapping.

[0095] Example 7:

[0096] This embodiment provides a nose pad-free glasses frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0097] The suction cup 51 is made of TPR thermoplastic rubber.

[0098] TPR thermoplastic rubber was chosen as the material for suction cup 51 due to its excellent elasticity, wear resistance, and sealing properties. TPR thermoplastic rubber also allows suction cup 51 to better conform to the user's face while maintaining a certain degree of adsorption, increasing wearing stability. Furthermore, the elasticity and wear resistance of TPR thermoplastic rubber ensure the durability and comfort of suction cup 51 during long-term use.

[0099] Example 8:

[0100] This embodiment provides a nose pad-free glasses frame, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0101] The soft cushion layer 32 is made of memory foam, and a plurality of anti-slip bumps 10 are provided on the inner side of the soft cushion layer 32 .

[0102] Memory foam has excellent shape memory ability and uniform pressure distribution. When the soft cushion layer 32 is memory foam, it can automatically adapt and fit according to the user's ear contour, providing a comfortable wearing experience. At the same time, the slow rebound characteristics of memory foam can also effectively reduce the feeling of oppression caused by long-term wearing.

[0103] Several anti-slip bumps 10 are located on the side of the memory foam closest to the face. These bumps increase friction between the soft cushioning layer 32 and the wearer's ear skin, preventing the glasses from slipping due to movement or shaking during wear. These anti-slip bumps 10 effectively enhance wearing stability and ensure the glasses remain correctly positioned during use.

[0104] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
