Abstract
Description
Technical Field
[0001] This utility model relates to the field of eyeglasses technology, and in particular to a templeless reading glasses. Background Technology
[0002] Reading glasses are convex lenses, primarily designed to meet the needs of middle-aged and elderly people with presbyopia. However, existing reading glasses present several challenges for seniors: First, since most presbyopia only affects near vision but not distant vision, seniors typically don't wear reading glasses for extended periods. This necessitates carrying them around. To minimize space requirements in cases, existing reading glasses are often designed to be foldable or retractable. While this saves space, the gap between the frame and temples remains when folded, requiring a thicker case. Second, due to thinner skin and osteoporosis, seniors need lighter glasses to reduce pressure on the nose. However, existing reading glasses usually have temples, adding to the weight. Summary of the Invention
[0003] To address the aforementioned issues, this invention provides a templeless reading glasses that offers high comfort, saves space when placed in a glasses case, and is easy to carry.
[0004] The technical solution of this utility model: A templeless reading glasses, comprising a frame, a nose pad assembly connected to the frame, and a positioning assembly connected to the frame. The positioning assembly includes a connecting rope fixedly connected to the frame, a positioning block connected to the connecting rope, and two stop blocks slidably connected to the positioning block. There are two connecting ropes, which are respectively fixedly connected to the left and right sides of the frame. The positioning block is provided with two sliding grooves and two first limiting holes. The first limiting holes penetrate the sliding grooves, and the axial direction of the first limiting holes is perpendicular to the opening direction of the sliding grooves. The stop blocks are provided with second limiting holes. A first return spring is provided between the stop block and the inner wall of the sliding groove. When the first return spring is compressed by a certain distance, the first limiting hole can be coaxially set with the second limiting hole. The connecting rope passes through the first limiting hole and the second limiting hole respectively.
[0005] Using the above technical solution, when a user needs to wear reading glasses, firstly, the frame is placed on the user's face, and the nose pad assembly is placed on the bridge of the nose. Then, the connecting rope is wrapped around the user's head, so that the connection end of the connecting rope and the positioning block is located at the back of the user's head. Then, the stop block is pressed, so that the first return spring is compressed a certain distance until the first and second limiting holes are in a coaxial state. At this time, the end of the connecting rope is pulled until the connection point of the connecting rope and the positioning block contacts the back of the head. Then, the stop block is released, so that the first and second limiting holes are not in a coaxial state, and the connecting rope is clamped. At this time, the connecting rope is in a taut state, and the frame, connecting rope, and positioning block form a closed loop and fit against the user's head, thereby ensuring that the position of the frame is fixed. The advantage of this is that it reduces the weight of the temples, which can further reduce the overall weight of the reading glasses and reduce the pressure on the bridge of the nose when the user wears the glasses. In addition, when storing the glasses, the thickness of the glasses case only needs to be adapted to the thickness of the frame, which greatly reduces the storage space required for the reading glasses and makes it convenient for users to carry them with them.
[0006] Further features of this invention: the positioning block is arc-shaped, the positioning block is adapted to the shape of the back of the human head, and the connecting rope is made of rubber.
[0007] By adopting the above technical solution, since the positioning block is adapted to the shape of the back of the human head, the comfort of users when wearing glasses can be greatly improved. In addition, since the connecting rope is made of rubber, which has a certain elasticity and a long service life, the comfort of users when wearing glasses can be further improved.
[0008] A further feature of this invention is that the nose pad assembly includes a connecting block fixedly connected to the frame, a connecting shaft slidably connected to the connecting block, a second return spring wound around the connecting shaft, and a nose pad element fixedly connected to the connecting shaft. The two ends of the second return spring are respectively fixedly connected to the connecting block and the nose pad element. There are two nose pad assemblies, and the two nose pad assemblies are symmetrically arranged with the central axis of the frame as the axis.
[0009] Using the above technical solution, when a user wears glasses, the two nose pads contact the sides of the nose bridge respectively. The nose bridge applies a reaction force to the nose pads, causing the second return spring to compress a certain distance until the distance between the two nose pads matches the width of the user's nose bridge. This further improves the user's comfort when wearing reading glasses. A further feature of this invention is that the nose pads are equipped with anti-slip pads, the shape and size of which are adapted to the nose pads.
[0010] By adopting the above technical solution, since the nose pad element is equipped with an anti-slip pad, the anti-slip pad can increase the friction between the nose pad element and the user's nose bridge, thereby preventing the frame from slipping off when the user wears glasses, and thus further improving the user's comfort when wearing glasses.

Detailed Implementation
[0014] like Figure 1-2 As shown, a type of templeless reading glasses includes a frame 1, a nose pad assembly 2 connected to the frame 1, and a positioning assembly 3 connected to the frame 1. The positioning assembly 3 includes a connecting rope 4 fixedly connected to the frame 1, a positioning block 5 connected to the connecting rope 4, and two stop blocks 6 slidably connected to the positioning block 5. There are two connecting ropes 4, which are fixedly connected to the left and right sides of the frame 1, respectively. The positioning block 5 is provided with two sliding grooves 7 and two first limiting holes 8. The first limiting holes 8 penetrate the sliding grooves 7, and the axial direction of the first limiting holes 8 is perpendicular to the opening direction of the sliding grooves 7. The stop blocks 6 are provided with second limiting holes 9. A first return spring 10 is provided between the stop blocks 6 and the inner wall of the sliding grooves 7. When the first return spring 10 is compressed by a certain distance, the first limiting holes 8 can be coaxially set with the second limiting holes 9. The connecting ropes 4 pass through the first limiting holes 8 and the second limiting holes 9, respectively.
[0015] When a user needs to wear reading glasses, first, place the frame 1 on the user's face and the nose pad assembly 2 on the bridge of the nose. Then, wrap the connecting rope 4 around the user's head so that the connection end of the connecting rope 4 and the positioning block 5 is located at the back of the user's head. Then, press the stop block 6 to compress the first return spring 10 a certain distance until the first limiting hole 8 and the second limiting hole 9 are coaxial. At this time, pull the end of the connecting rope 4 until the connection point of the connecting rope 4 and the positioning block 5 contacts the back of the head. Then, release the stop block 6 so that the first limiting hole 8 and the second limiting hole 9 are coaxial. When the positioning hole 9 is not in a coaxial state, the connecting rope 4 will be clamped. At this time, the connecting rope 4 is in a taut state, and the frame 1, the connecting rope 4, and the positioning block 5 form a closed loop and fit against the user's head, thereby ensuring that the position of the frame 1 is fixed. The advantage of this is that it reduces the weight of the temples, which can further reduce the overall weight of the reading glasses and reduce the pressure on the bridge of the nose when the user wears the glasses. In addition, when storing the glasses, the thickness of the glasses case only needs to be adapted to the thickness of the frame 1, which greatly reduces the storage space required for the reading glasses and makes it convenient for the user to carry them with them.
[0016] The positioning block 5 is arc-shaped and is adapted to the shape of the back of the human head. The connecting rope 4 is made of rubber.
[0017] Since the positioning block 5 is adapted to the shape of the back of the human head, it can greatly improve the comfort of users when wearing glasses. In addition, since the connecting rope 4 is made of rubber, which has a certain elasticity and a long service life, it can further improve the comfort of users when wearing glasses.
[0018] The nose pad assembly 2 includes a connecting block 11 fixedly connected to the frame 1, a connecting shaft 12 slidably connected to the connecting block 11, a second return spring 13 wound around the connecting shaft 12, and a nose pad element 14 fixedly connected to the connecting shaft 12. The two ends of the second return spring 13 are fixedly connected to the connecting block 11 and the nose pad element 14, respectively. There are two nose pad assemblies 2, and the two nose pad assemblies 2 are symmetrically arranged with the central axis of the frame 1 as the axis.
[0019] When a user wears glasses, the two nose pads 14 contact the sides of the bridge of the nose respectively. The bridge of the nose will exert a reaction force on the nose pads 14, thereby compressing the second return spring 13 by a certain distance until the distance between the two nose pads 14 matches the width of the user's bridge of the nose. This can further improve the user's comfort when wearing reading glasses.
[0020] The nose pad element 14 is provided with an anti-slip pad 15, which is adapted to the shape and size of the nose pad element 14.
[0021] Because the nose pad element 14 is provided with an anti-slip pad 15, the anti-slip pad 15 can increase the friction between the nose pad element 14 and the user's nose bridge, thereby preventing the frame 1 from slipping off when the user wears glasses, thus further improving the user's comfort when wearing glasses.
