Description

Technical Field

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

[0002] Existing glasses are mainly composed of a frame and temples, which are connected by a hinge. When worn, the frame and temples are mainly supported by the nose bridge and the outer ear. However, long-term wearing can easily leave indentations on the nose bridge and the outer ear, causing discomfort. In addition, people with injured nose bridges or injured or even missing outer ears cannot provide support and are unable to wear glasses.

[0003] A Chinese invention patent, publication number CN101939688B, discloses a nose-pad-less frame and a method for supporting such a frame. This solution incorporates a movable support component on the temples to adjust the frame to accommodate varying head circumferences. While this solution largely addresses the issue of relying on nose pads to support the frame, it is not stable and can easily fall in everyday situations.

[0004] Therefore, it is very necessary to develop a pair of nose pad-free glasses that are stable and convenient to wear. This not only prevents the nose pads from pressing on the bridge of the nose, but also provides a stable fit and is suitable for a variety of life situations. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model proposes a pair of nose-pad-free glasses that are stable and convenient to wear.

[0006] To achieve the above-mentioned purpose, the present embodiment provides a pair of glasses without nose pads, comprising a frame without nose pads and two front temples mounted on both sides of the frame, two rear temples hingedly connected to the two front temples, and a strap connected to the hinged ends of the rear temples. By adjusting the hinge angles of the two rear temples and cooperating with the strap, the frame can be worn stably.

[0007] Based on the above, the front temple and the rear temple are hinged, and the angle is adjusted according to different head circumferences, so that the rear temple and the head generate friction. The temple strap is worn on the head to provide an auxiliary pulling force to the rear temple, making the frame more stable and convenient to wear.

[0008] Furthermore, cylinders are provided on both sides of the frame, and the frame is rotatably engaged with the front temples through the cylinders.

[0009] Based on the above, the frame and the front frame are rotatably matched through the cylinder, and the angle between the frame and the front temple can be freely adjusted according to needs.

[0010] Furthermore, a spherical groove is provided on the rear temple, and spherical connecting blocks are provided at both ends of the mirror strap. The spherical groove and the spherical connecting block form a spherical pair after cooperation. The mirror strap can be adjusted in multiple directions through the spherical pair to obtain a comfortable wearing angle.

[0011] Based on the above, the spherical pair makes it more convenient to wear the eyeglass strap, and the angle direction can be freely adjusted, making it easy to find the best force point.

[0012] Furthermore, a tension adjustment slot is provided on the spherical groove, and tension adjustment holes are provided on both sides of the tension adjustment slot, and the size of the tension adjustment slot is adjusted by passing a tension adjustment screw through the tension adjustment hole.

[0013] Based on the above, the tension adjustment slit facilitates the installation of the spherical connecting block on the spherical groove, and the spherical groove is locked by using the tension adjustment screw through the tension adjustment hole.

[0014] Furthermore, the frame and the temples are both made of ems-tr90, and the strap is made of modified PC.

[0015] Based on the above, the EMS-TR90 material has the characteristics of light weight, high toughness, good wear resistance and strong impact resistance, and is durable and more stable to wear.

[0016] In order to more clearly illustrate the above features of the present invention and the objectives to be achieved, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figures 1 to 6 As shown, a pair of nose pad-free glasses includes a frame 1, front temples 2, rear temples 3, and a strap 4. Cylinders 5 are provided on both sides of the frame 1. The frame 1 is rotatably engaged with the front temples 2 via the cylinders. The frame 1 can rotate 360° around the centerline of the cylinder 5. The angle between the frame 1 and the front temple 2 can be adjusted according to the needs of different scenes. The front temple 2 and the rear temple 3 are hinged to form a swinging pair. The rear temple 3 can rotate 180° around the swinging pair. The tightness of the hinge between the front temple 2 and the rear temple 3 can be adjusted by a tension adjustment screw 11. The rear temple 3 exerts pressure on the head, thereby generating friction between the rear temple 3 and the head. At the same time, the rear end of the rear temple 3 is connected to the strap 4. The strap 4 is worn behind the head to provide an auxiliary force to the rear temple 3, allowing the frame 1 to be worn stably.

[0025] The rear temple 3 is provided with a spherical groove 6, which is provided with a tension adjustment slit 9. The tension adjustment slit 9 is flanked by tension adjustment holes 10. The size of the tension adjustment slit 9 can be adjusted by passing a tension adjustment screw 11 through the tension adjustment holes 10. The spherical groove 6 and the spherical connecting block 7 on the temple strap 4 form a spherical pair 8. When installing the temple strap 4 on the rear temple 3, the tension adjustment screw 11 in the tension adjustment hole 10 is first loosened, the spherical connecting block 7 is then installed into the spherical groove 6, and the tension adjustment screw 11 in the tension adjustment hole 10 is subsequently tightened. The spherical pair 8 makes wearing the temple strap 4 more convenient, allowing for free adjustment of the angle of the temple strap 4 and facilitating the search for the optimal force point.

[0026] The frame 1 and the temples are made of EMS TR90, and the band 4 is made of modified PC. The EMS-TR90 material has the characteristics of light weight, high toughness, good wear resistance and strong impact resistance, and is durable and more stable to wear.

[0027] The specific implementation of this embodiment is as follows: This embodiment differs from conventional glasses in that conventional glasses generally rely on nose pads to support the frame, while this embodiment removes the nose pad structure and arranges the rear temple 3 to cooperate with the temple strap 4 to bear force, thereby ensuring stable wearing of the glasses. The frame 1 and the front temple 2 are rotatably matched. When not being worn, the frame 1 can be rotated to be flush with the front temple 2, saving storage space. When wearing, the angle between the front temple 2 and the rear temple 3 is adjusted so that the rear temple 3 applies pressure to the head, thereby generating friction between the rear temple 3 and the head. At the same time, the rear end of the rear temple 3 is connected to the temple strap 4. The temple strap 4 is worn behind the head, providing auxiliary force to the rear temple 3, ensuring stable wearing of the frame 1.

[0028] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or replacements of the present invention made by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
