Description

Technical Field

[0001] The present invention belongs to the technical field of optical glasses, and specifically relates to a detachable neck-mounted presbyopic glasses.

Background Art

[0002] Presbyopic glasses are glasses for presbyopic people. However, since presbyopic glasses cannot be continuously worn, wearing and removal may be alternately performed. For convenience of wearing, some users hang the presbyopic glasses around their necks when they do not use them.

[0003] For example, Chinese Utility Model CN203811914U discloses a presbyopic glasses comprising a rim, temples and lenses, wherein the rim consists of a left rim and a right rim connected by magnetic attraction, the number of the temples is one, one end of the temple is hinged to the left rim, and the other end of the temple is hinged to the right rim. Since the left rim and the right rim are connected by magnetic attraction to form a closed loop shape, when worn in this state, even if the glasses fall from the bridge of the nose, they will not fall to the ground, and lens breakage is avoided.

[0004] However, connection only by magnets is difficult to provide sufficient connection stability, and is also prone to displacement, which affects the use.

[Figure 2] This is a schematic diagram of the structure when the rims of this invention are spaced apart. [Figure 3] This is a front view of the present invention (in the separated state). [Figure 4] This is a schematic diagram of the first rim. [Figure 5] This is a schematic diagram of the first rim from a different angle. [Figure 6] This is a schematic diagram of the second rim. [Modes for carrying out the invention]

[0013] The technical means in embodiments of the present invention will be clearly and completely described below based on the drawings of the embodiments of the present invention, but it is clear that the embodiments described are only a part of the present invention and not all embodiments. Any other embodiments that a person skilled in the art could obtain without creative work based on the embodiments of the present invention shall all be within the scope of the protection of the present invention.

[0014] It should be noted that all directional indicators in the embodiments of this invention (for example, up, down, left, right, front, back, etc.) are simply for the purpose of describing the relative positional relationships and motion conditions between each component in a specific orientation (for example, the orientation shown in the drawing). When this specific orientation changes, these directional indicators also change accordingly.

[0015] As shown in Figures 1 and 3, the detachable neck-worn reading glasses disclosed herein comprise a first rim 100, a second rim 200, and two temples 300 hinged to the first rim 100 or the second rim 200. The first rim 100 and the second rim 200 constitute a complete rim for holding the lens. The ends of the two temples 300 are connected via a connecting band 400 to form a closed loop. Here, the first rim 100 and the second rim 200 are separable from each other (as shown in Figure 2), and when not being worn, they are hung around the neck via the connecting band. The connecting band is made of an elastic material. In some other embodiments, the connecting band may be a braided cord, a metal chain, or the like.

[0016] As shown in Figure 4, the insertion portion 110 is integrally molded at the left end of the first rim 100 (when viewed from the perspective of Figure 4). An elastic arm 111 is formed in the side wall of this insertion portion 110 via a through relief hole 113 (shown in Figure 5). One end of the elastic arm 111 is connected to the inner wall of the relief hole 113, and the main body portion is suspended in mid-air. A positioning bump 112 that protrudes outward is provided at the free end of the elastic arm 111. In this embodiment, the cross-section of this positioning bump 112 is circular, and the tip edge of the insertion portion 110 is machined to a fillet, giving the elastic arm an overall hemispherical shape. By designing it to be slightly elongated vertically, its positioning can be controlled more effectively.

[0017] As shown in FIG. 6, a connecting portion 210 is provided at one end of the second rim 200. A slot 211 for detachably connecting to the insertion portion 110 is provided in the connecting portion. At the right end of the second rim 200, a corresponding connecting portion 210 is provided, and a slot 211 conforming to the shape of the insertion portion 110 is opened inside the connecting portion 210. A guide slope 213 is machined on the opening edge of the slot 211. The guide slope 213 is provided at the front end of the positioning hole 212 to facilitate guiding the deformation of the elastic arm. A positioning hole 212 corresponding to the position of the positioning bump 112 is opened on the inner wall of the slot 211. The end face of the connecting portion 210 constitutes a first mating surface 214, and the end of the first rim 100 constitutes a second mating surface 114 that matches the first mating surface 214.

[0018] When in use, the user aligns the insertion portion 110 of the first rim 100 with the slot 211 of the second rim 200 and gently pushes it in. During the insertion process, first, the guide slope 213 guides the alignment of the insertion portion 110. As the insertion progresses, the positioning bump 112 abuts against the inner wall of the slot 211, compressing the elastic arm 111 and causing it to elastically deform into the escape hole 113. When the insertion portion 110 reaches a predetermined depth (i.e., just before the first mating surface 214 and the second mating surface 114 come into close contact), the positioning bump 112 just moves into the positioning hole 212, and the elastic arm 111 instantly returns, propelling the engagement of the positioning bump 112 into the positioning hole 212. At the same time, the two mating surfaces come into firm contact. At this time, there is an obvious "click" feeling and sound, indicating that the assembly is complete. In this way, the first rim 100 and the second rim 200 are firmly connected.

[0019] When disassembling, the user only needs to hold the first rim 100 and the second rim 200 by hand and apply an opposite pulling force. This force can deform the elastic arm 111 again, pull the positioning bump 112 out of the positioning hole 212, and easily separate the two parts.

[0020] The connection between the first rim 100 and the second rim 200 relies on the insertion and connection parts, and the positioning relies on the engagement of the positioning bump and positioning hole in the elastic arm, resulting in higher reliability and preventing material deformation even after prolonged use.

[0021] The ends of the two temples 300 are connected via an elastic silicone connecting band 400. Cover holes are provided at both ends of the connecting band 400, and the ends of the temples 300 are inserted into the cover holes and secured with interference fits. Even after the glasses are disassembled, the first rim (with one temple attached) and the second rim (with the other temple attached) remain connected via this elastic connecting band 400, forming a loop, and can be simply hung around the neck when not being worn. To prevent loss, the two can also be secured together using the insertion and connecting parts when hanging them around the neck.

[0022] It is easy to disassemble, the connection is secure, and separation force can be applied to the connection point with one hand. Operation is more convenient and suits the habits of elderly users.

[0023] The embodiments are not intended to limit the present invention. Any modifications made based on the concept of the present invention shall be included within the scope of protection of the present invention.
