Description

Technical Field

[0001] This utility model relates to the field of eyeglass frame technology, and in particular to an elastic eyeglass frame. Background Technology

[0002] Eyeglass frames consist of main parts such as the frame, bridge, hinges, and temples. The frame is where the lenses are mounted; the bridge connects the left and right frames to secure the lenses; the hinges connect the frame and temples; and the temples hook onto the ears to fix the frame in place. In current technology, because eyeglass frames are mostly made of metal or hard plastic, they are inherently rigid and lack elasticity, making them prone to pinching the face and causing discomfort after prolonged wear. Furthermore, the temple length is not adjustable; any misalignment in length can lead to an uncomfortable fit and the frames easily slipping off. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide an elastic eyeglass frame that solves problems such as poor elasticity of eyeglass frames and the inability to adjust temple length.

[0004] According to this utility model, an elastic eyeglass frame includes a frame, temples, and an elastic component. The frame has symmetrically arranged L-shaped connectors on both sides. One end of the elastic component is rotatably connected to one end of the L-shaped connector. The elastic component includes a square sleeve, a large spring, a small spring, and two insert plates. Multiple sets of limiting holes are symmetrically arranged on the upper and lower walls of the left half of the square sleeve. T-shaped slots are provided on the left and right inner walls of the opening at the right end of the square sleeve. A large spring and a small spring are respectively fixed at the middle of the inner sides of the two insert plates. The temple has a cylinder at its front end, with a spring cavity inside. The top and bottom walls of the cylinder have insertion holes communicating with the spring cavity. A T-shaped pin is inserted into each insertion hole. A return spring is provided in the spring cavity between two T-shaped pins. The cylinder is inserted from the opening at the right end of the square sleeve so that the two T-shaped pins are inserted into a set of limiting holes. Insert plates are inserted into the two T-shaped slots inside the square sleeve, and the large spring and small spring abut against the side walls of the temple.

[0005] In some embodiments of this utility model, the spacing between adjacent limiting holes on the square sleeve is 3-5mm, and the number of upper limiting hole groups on the square sleeve is 3-5.

[0006] In some other embodiments of this utility model, the inner diameter of the square sleeve at the opening on the right side is 6-8mm, the thickness of the temple inserted into the square sleeve is 1.0-1.2mm, the length of the large spring is 4-6mm, and the length of the small spring is 2-4mm.

[0007] In some other embodiments of this utility model, the temple is fitted with a rubber sleeve at the position where it is inserted into the square sleeve. The rubber sleeve includes a large rubber sleeve, a small rubber sleeve, and a flexible gradient rubber sleeve connecting the large rubber sleeve and the small rubber sleeve. The large rubber sleeve is fitted onto the square sleeve, the small rubber sleeve is fitted onto the temple, and the flexible gradient rubber sleeve is located at the insertion position of the square sleeve.

[0008] In some other embodiments of this invention, the temples are made of titanium alloy.

[0009] In this invention, the temples are elastic, which can adapt to wearers with different head sizes within a certain range, and the length of the temples can be adjusted to best fit the wearer's ear position, making them comfortable to wear. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] Reference Figure 1-5 A flexible eyeglass frame includes a frame 1, temples 2, and an elastic component 3. The frame 1 has symmetrically arranged L-shaped connectors 11 on both sides. One end of the elastic component 3 is rotatably connected to one end of the L-shaped connector 11. The elastic component 3 includes a square sleeve 31, a large spring 101, a small spring 102, and two insertable thin plates 10. The upper and lower walls of the left half of the square sleeve 31 are symmetrically provided with multiple sets of limiting holes 32. T-shaped slots are provided on the left and right inner walls of the opening at the right end of the square sleeve 31. The large spring 101 and the small spring 102 are respectively fixed at the middle positions of the inner sides of the two insertable thin plates 10. Spring 102, the temple 2 has a cylinder 4 at the front end, the cylinder 4 has a spring cavity, the top wall and bottom of the cylinder 4 are respectively provided with insertion holes communicating with the spring cavity, a T-shaped pin 6 is inserted into each insertion hole, and a return spring 5 is provided in the spring cavity between two T-shaped pins 6. The cylinder 4 is inserted from the right end opening of the square sleeve 31 so that the two T-shaped pins 6 are inserted into a set of limiting holes 32 respectively. Insertion plates 10 are respectively inserted into the two T-shaped slots in the square sleeve 31, and the large spring 101 and the small spring 102 abut against the two side walls of the temple 2 respectively.

[0020] Depending on the wearer's ear position or head size, insert the two T-shaped pins 6 into the appropriate limiting holes 32 to ensure a comfortable and snug fit. When not wearing the glasses, the large and small springs are in optimal condition with balanced force. When wearing the glasses, the large spring is compressed, applying pressure to the sides of the head with the temples, but the pressure is not significant and will not leave indentations. This prevents the temples from falling off and accommodates different head sizes, especially for those whose heads have become larger or thinner. The length of the temples 2 can be adjusted by pressing the T-shaped pins 6 inward and pulling the temples.

[0021] The spacing between adjacent limiting holes 32 on the square sleeve 31 is 3-5mm, and the square sleeve 31 has 3-5 sets of limiting holes 32. This allows for a maximum length adjustment of approximately 13-18mm, basically adapting to most head shapes.

[0022] The square sleeve 31 has an inner diameter of 6-8mm at the opening on the right side. The temple 2 has a thickness of 1.0-1.2mm when inserted into the square sleeve 31. The large spring 101 has a length of 4-6mm, and the small spring 102 has a length of 2-4mm. The temple has an adjustment range of 2-3mm at the opening and 8-15mm at the lens retraction lug, making it quite adaptable.

[0023] The temple 2 is fitted with a rubber sleeve at the insertion point into the square sleeve 31. The rubber sleeve includes a large rubber sleeve 7, a small rubber sleeve 8, and a flexible gradient rubber sleeve 9 connecting the large rubber sleeve 7 and the small rubber sleeve 8. The large rubber sleeve 7 is fitted onto the square sleeve 31, the small rubber sleeve 8 is fitted onto the temple, and the flexible gradient rubber sleeve 9 is positioned at the insertion point of the square sleeve 31. Gaps at the insertion point can easily allow dust to enter and cause fingers to get caught; the rubber seal provides greater safety.

[0024] The temples 2 are made of titanium alloy. They also have a certain degree of elasticity, making them more comfortable to wear.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
