Description

Technical Field

[0001] The utility model belongs to the technical field of glasses, and in particular relates to an outward-elastic structure of glasses legs. Background Art

[0002] Glasses are increasingly used in everyday life as tools for vision correction and shading. Spectacle frames primarily support the lenses, acting as a support for the eyes. They consist of a frame and two temples. The temples are hinged to the temples, which are located on either side of the frame and can be hooked onto the wearer's ears to secure them in place.

[0003] Due to the structural limitations of the temples and the tips, conventional glasses have low elasticity when worn, which can cause a sense of oppression and low comfort for the wearer. Therefore, in the prior art, elastic materials are usually used to make the temples, so that the temples have an outward elastic function of bending outward, effectively reducing the sense of oppression when worn and improving comfort. However, this design still has at least the following problems:

[0004] First, because the temples have special requirements for materials, users need to pay a higher cost when purchasing glasses or replacing temples;

[0005] Secondly, due to the lack of a limit design, the temples are easily pulled hard and over-expanded when the user puts on or takes off the glasses, resulting in permanent deformation and loss of the external spring function, resulting in a short service life. Utility Model Content

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] See attached Figure 1 -Attached Figure 11 A structure for external elasticity of eyeglass legs comprises an eyeglass leg 1, an elastic rod 2 and a frame 3; a stopper 11 is provided on the eyeglass leg 1; the elastic rod 2 is mounted on the eyeglass leg 1 and corresponds to the stopper 11, and a movable gap 20 is provided between the elastic rod 2 and the stopper 11; a stud 4 is mounted on the frame 3, and the stud 4 is hinged to the elastic rod 2 so that the eyeglass leg 1 can be folded or expanded; wherein, by bending the fully expanded eyeglass leg 1, the elastic rod 2 can be driven to deform at the movable gap 20, and the stopper 11 can abut against the deformed elastic rod 2.

[0037] Specifically, when the temple 1 is in a folded state or in an incompletely expanded state, the elastic rod 2 does not deform; when the temple 1 is in a fully expanded state, if the fully expanded temple 1 continues to be bent, the elastic rod 2 can be driven to deform at the movable gap 20 to achieve the outward expansion of the temple 1, thereby facilitating wearing and improving comfort; when the elastic rod 2 is shaped to a certain extent, it will abut against the block 11, so that the block 11 limits the deformation amplitude of the elastic rod 2, thereby avoiding permanent deformation of the elastic rod 2 due to abnormal operation.

[0038] Therefore, compared with the existing technology, this structure connects the frame 3 and the temple 1 by designing an elastic rod 2, so that the temple 1 can be directly made of conventional materials while having the external spring function, effectively reducing the overall cost, making it convenient for users to replace the temple 1 as needed, and meeting the user's personalized needs; by designing a block 11 to limit the deformation amplitude of the elastic rod 2, it is prevented that the elastic rod 2 over-expands and loses the external spring function, thereby extending the overall service life.

[0039] See attached Figure 4 -Attached Figure 9The head end of the stopper 11 is away from the temple 1 and gradually recessed, and the portion of the elastic rod 2 corresponding to the head end of the stopper 11 is curved and away from the stopper 11; this design facilitates the formation of the movable gap 20 and prevents the elastic rod 2 from protruding too much from the temple 1 and bumping against the user's facial skin; at the same time, the design of the elastic rod 2 being curved and away from the stopper 11 can also make the elastic rod 2 have sufficient elasticity.

[0040] See attached Figure 4 -Attached Figure 9 There is an included angle α between the elastic rod 2 and the stopper 11. Before the elastic rod 2 is deformed, the movable gap 20 maintains the initial state, at which time 5°≤α≤15°; after the elastic rod 2 is deformed, the movable gap 20 is reduced, and α can be reduced to 0°.

[0041] Among them, within the angle range of 5°≤α≤15°, it can not only ensure that the elastic rod 2 has sufficient deformation space, ensuring the outward elastic ability of the temple 1, but also ensure that the elastic rod 2 can recover quickly after deformation, avoiding excessive deformation of the elastic rod 2, and at the same time limit the outward elastic amplitude of the temple 1 within the normal range, so that it meets the needs of normal people when wearing glasses.

[0042] See attached Figure 4 -Attached Figure 9 The hinged connection between the elastic rod 2 and the pile head 4 is various, and most of them belong to conventional mechanical structures, so the present invention does not limit this. For the sake of convenience, in this embodiment, the elastic rod 2 is provided with a rotation cavity 21 on the end away from the temple 1, and a notch 210 connected to the outside world is opened on the wall of the rotation cavity 21; the pile head 4 includes a rotating block 41 and a connecting rod 42, the rotating block 41 is hinged in the rotating cavity 21, and the connecting rod 42 passes through the notch 210 to the outside world and is fixed to the frame 3, and the connecting rod 42 can move in the notch 210 as the temple 1 swings, and when the temple 1 is fully expanded, the connecting rod 42 abuts against the side wall of the notch 210, so that the rotating block 41 cannot continue to rotate, and then smoothly transmits the force applied to the temple 1 to the elastic rod 2. At this time, continuing to expand the frame 3 can drive the elastic rod 2 to deform, thereby realizing the outward elasticity of the temple 1.

[0043] Specifically, compared with the conventional hinge method, the coordination between the rotating block 41 and the rotating cavity 21, as well as the coordination between the connecting rod 42 and the notch 210, can, on the one hand, make the overall structure more compact, and can effectively limit the swing angle of the temple 1 while improving the rotation stability; on the other hand, the connection between the elastic rod 2 and the pile head 4 can be hidden to improve the appearance.

[0044] Furthermore, based on the above content, it can be known that the expansion angle of the temple 1 is determined by the position of the side wall of the notch 210. In order to make the glasses suitable for ordinary people, in the present invention, before the elastic rod 2 is deformed, the expansion angle range of the temple 1 is 0-90°. When the temple 1 expands 90°, the connecting rod 42 abuts the side wall of the notch 210.

[0045] It should be noted that the manufacturer may also set the expanded angle of the temple 1 to above 90°, and adjust the position of the side wall of the notch 210 at the same time, so that after the temple 1 expands to a corresponding angle, the connecting rod 42 abuts against the side wall of the notch 210, so as to meet the needs of special groups of people. This is not restricted in the present invention.

[0046] See attached Figure 4 -Attached Figure 11 Screws 5 can be used to fix the connecting rod 42 and the frame 3, the rotating block 41 and the elastic rod 2, and the elastic rod 2 and the temple 1. This design facilitates the early assembly and later disassembly and replacement of the various components, thereby improving convenience.

[0047] It should be noted that, for the non-hinged connection between the connecting rod 42 and the frame 3, and the elastic rod 2 and the temple 1, in addition to being fixed by screws 5, they can also be fixed by bonding, welding, etc., and the present invention does not impose any restrictions on this.

[0048] See attached Figure 4 -Attached Figure 9 The temple 1 is provided with a panel 12 on the upper and lower sides of the stopper 11, and the two panels 12 and the stopper 11 enclose a receiving cavity 10; one end of the elastic rod 2 connected to the pile head 4 is located outside the receiving cavity 10, and the main body of the elastic rod 2 is movably arranged in the receiving cavity 10, and a movable gap 20 is formed in the receiving cavity 10.

[0049] Specifically, the design of the accommodating cavity 10 allows the elastic rod 2 to be better hidden in the temple 1, which not only improves the aesthetics, but also prevents the elastic rod 2 from protruding from the temple 1 and bumping against the user's facial skin. At the same time, it can also prevent the movable gap 20 from being exposed, solving the problem of the user's hair easily falling into the movable gap 20 and being clamped.

[0050] See attached Figure 4 -Attached Figure 9 The temple 1, the stopper 11 and the two panels 12 are integrally formed to facilitate production; the outer side surface of the temple 1 and the outer side surface of the stopper 11 have a smooth transition to make the appearance smooth, further improving the aesthetics; the inner side surface of the temple 1 and the inner side surfaces of the two panels 12 have a smooth transition to avoid the connection between the temple 1 and the two panels 12 from protruding and scratching the user's facial skin.

[0051] See attached Figure 4 -Attached Figure 7 and attached Figure 10 -Attached Figure 11At least one of the enclosures 12 is provided with a slide groove 12h, and the slide groove 12h is set on the top wall or bottom wall of the accommodating cavity 10; the elastic rod 2 is provided with a slider 2h that slides with the slide groove 12h. When the elastic rod 2 is deformed and approaches the stopper 11, the slider 2h moves along the slide groove 12h.

[0052] Specifically, the combined use of the slide groove 12h and the slider 2h can not only guide the elastic rod 2 to deform in a specific direction, avoid invalid deformation of the elastic rod 2, and improve the stability of use; but also buffer the elastic rod 2, avoid the elastic rod 2 from violently colliding with the block 11 due to excessive expansion of the temple 1, and effectively extend the service life of the elastic rod 2 and the block 11.

[0053] See attached Figure 1 -Attached Figure 7 The elastic rod 2 is made of elastic metal or plastic, such as copper alloy, spring steel, TPE, polyurethane, etc. Due to the variety of related materials, this invention does not limit this; this type of material has good deformation and recovery capabilities, and can return to its original shape after the temple 1 is elastic.

[0054] It should also be noted that although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
