Abstract
Description
An adjustable size ear hook and eyeglass frame Technical Field
[0001] This utility model relates to the field of eyeglass accessories, and in particular to an adjustable size ear loop and eyeglass frame. Background Technology
[0002] In existing eyeglass frame designs, the temples mainly use the lugs at their ends to hook onto the wearer's ears and behind the ears, forming a constraint and support to hold the entire eyeglass frame to the user's face and ensure a stable fit. However, the temples of current mainstream eyeglass frame products have a fixed, non-adjustable length after manufacturing.
[0003] The temple design in the above solution presents a compatibility issue when facing users with different head circumferences. Due to the differences in individual users' head sizes, the optimal temple length required for each user to obtain a stable and comfortable wearing experience is also different. In order to meet the actual wearing needs of different users, eyewear manufacturers need to produce a series of temples with different lengths to fit the same style of glasses. This reliance on providing multiple sizes not only increases production costs but also increases the difficulty of supply chain management. Summary of the Invention
[0004] The purpose of this invention is to provide an adjustable size ear loop and eyeglass frame, with the temples adjusted via the ear loop to fit the optimal length for the user's head.
[0005] The technical solution adopted by the adjustable-size ear loop and eyeglass frame disclosed in this utility model is as follows:
[0006] The device comprises two symmetrical main bodies and two limiting members. One end of each main body has a slot with a limiting part inside. The other end of each main body extends into a tail with an arc-shaped structure and a contact part extending from the end of the tail. A sliding groove runs through the middle of each main body, with multiple spaced protrusions extending from the groove. A groove is formed between two adjacent protrusions. The two ends of the sliding groove are close to the slot and the tail, respectively. The main body, tail, and contact part are all made of elastic deformable material. The limiting member is connected to the end of the contact part and slides within the sliding groove. The limiting member can be detachably connected by engaging with one of the grooves.
[0007] As a preferred embodiment, the plurality of protrusions are arranged in two rows, and the two rows of protrusions are symmetrically arranged vertically within the groove.
[0008] As a preferred embodiment, the main body has a through groove communicating with the slide, and the limiting member has a connecting part extending from it, the connecting part being embedded in the end of the contact part.
[0009] As a preferred embodiment, the frame includes ear loops and a frame, with temples rotatably connected to both sides of the frame. The two temples are respectively inserted into two slots, and the limiting part constrains the temples within the slots.
[0010] As a preferred embodiment, the limiting part consists of multiple spaced limiting holes located on the inner wall of the slot, and multiple spaced protrusions extend from the outer side of the temple, the protrusions being engaged in adjacent limiting holes.
[0011] As a preferred embodiment, the limiting part consists of multiple limiting blocks arranged at intervals, with the multiple limiting blocks arranged in two rows. The two rows of limiting blocks are symmetrically arranged vertically within the slot, and the two rows of limiting blocks clamp the outer side of the temple.
[0012] The beneficial effects of the adjustable-size ear loops and eyeglass frames disclosed in this utility model are:
[0013] The temples are inserted into slots in the main body, and the limiting part securely connects the main body to the temples. When the user wears the glasses, the contact part hooks behind the wearer's ear, and the main body rests flat on the wearer's ear, thus providing restraint and support. When the temples need to fit users with smaller head sizes, the limiting part is pushed to slide within the groove, causing it to engage in a groove closer to the slot. The limiting part pulls the contact part and the temple end to deform elastically, shortening the distance between the frame and the contact part, thus shortening the effective length of the temples. When the temples need to fit users with larger head sizes, the limiting part is pushed to slide within the groove, causing it to engage in a groove closer to the temple end. The limiting part pulls the contact part and the temple end to deform elastically, lengthening the distance between the frame and the contact part, thus lengthening the effective length of the temples. This allows the effective length of the temples to be adjusted according to the user's head size via ear hooks. The grooves within the sliding part are multiple, allowing for multi-level adjustment. Furthermore, the grooves can engage and restrain the limiting part in its current position, ensuring that the frame and the contact part maintain their current distance. Attached Figure Description

[0020] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:
[0021] Example 1, please refer to Figures 1-3.
[0022] This utility model discloses an adjustable-size ear loop and eyeglass frame, comprising two symmetrical main bodies 1, two limiting members 2, and a frame 3.
[0023] One end of the main body 1 is provided with a slot 11, and a limiting part is provided inside the slot 11;
[0024] The other end of the main body 1 extends to a tail leg 12. In this embodiment, the tail leg 12 is preferably arc-shaped. The end of the tail leg 12 extends to a contact portion 121. In this embodiment, the contact portion 121 is preferably arc-shaped. The contact portion 121 is folded on the tail leg 12 to form an acute angle, so that the end of the contact portion 121 bends back and approaches the main body 1.
[0025] Furthermore, in this embodiment, the main body 1, the tail foot 12, and the contact portion 121 are preferably made of elastic deformable material, so that when the contact portion 121 is pulled, the tail foot 12 elastically deforms on the main body 1, and the contact portion 121 elastically deforms on the tail foot 12, thereby increasing the acute angle between the contact portion 121 and the tail foot 12.
[0026] A groove 13 runs through the middle of the main body 1. The two ends of the groove 13 are close to the slot 11 and the tail 12, respectively. Multiple protrusions 131 are arranged at intervals in the groove 13. In this embodiment, the multiple protrusions 131 are preferably arranged in two rows, and the two rows of protrusions 131 are symmetrically arranged in the groove 13. Both rows of protrusions 131 are parallel to the guide path of the groove 13.
[0027] Furthermore, a groove is formed between two adjacent protrusions 131, and the distance between the upper and lower protrusions 131 is less than the diameter of the limiting member 2; a through groove 14 is provided on the main body 1, and the through groove 14 is connected to the sliding groove 13.
[0028] In this embodiment, the limiting member 2 is preferably cylindrical. The limiting member 2 is placed in the sliding groove 13 and slides. The limiting member 2 slides along the guide path of the sliding groove 13 and can be detachably connected by being inserted into one of the grooves. A connecting part 21 extends from the middle of the limiting member 2. The connecting part 21 passes through the through groove 14 and is embedded into the end of the contact part 121 and fixedly connected thereto. The limiting member 2 is fixedly connected to the end of the contact part 121 through the connecting part 21.
[0029] Both sides of the frame 3 are rotatably connected to temples 31, and the two temples 31 are respectively inserted into two slots 11, with the limiting part constraining the temples 31 within the slots 11.
[0030] When the user is wearing glasses:
[0031] Two contact parts 121 hook behind the wearer's ears respectively, and the eyeglasses frame is worn on the user's face through the ear loops; the two main bodies 1 are placed flat on the wearer's ears respectively, thereby supporting the ear loops and temples 31.
[0032] When it is necessary to adjust the effective length of the temple 31 to fit the user's head size:
[0033] By pushing the limiting member 2 out of the currently engaged groove, since the main body 1 is made of an elastic deformable material, the limiting member 2 slides and moves within the slide groove 13, causing the slide groove 13 to elastically deform, allowing the limiting member 2 to pass between the upper and lower protrusions 131 and engage in the next groove; when the limiting member 2 is engaged in the groove closer to the slot 11, the limiting member 2 pulls the contact part 121 through the connecting part 21, causing the contact part 121 to elastically deform on the tail 12, increasing the acute angle between the contact part 121 and the tail 12, and the tail 12 elastically deforms on the main body 1, thereby shortening the distance between the frame 3 and the contact part 121, shortening the effective length of the temple 31, and matching users with smaller head sizes;
[0034] By pushing the limiting member 2 out of the currently engaged groove, the limiting member 2 is inserted into a groove closer to the tail 12. The limiting member 2 pushes the contact part 121 through the connecting part 21, reducing the acute angle between the contact part 121 and the tail 12, thereby lengthening the distance between the frame 3 and the contact part 121, and lengthening the effective length of the temple 31 to match users with larger head sizes.
[0035] Example 2, please refer to Figures 1-4.
[0036] Based on the original embodiment 1, this embodiment preferably has a plurality of spaced limiting holes 111 arranged in a straight line and parallel to the slot 11; the limiting holes 111 are located on the inner wall of the slot 11 and penetrate through the inner wall of the slot 11 to communicate with the outside.
[0037] Furthermore, the outer side of the temple 31 has a plurality of spaced protrusions 311 arranged in a line, and the plurality of protrusions 311 are parallel to the plurality of limiting holes 111.
[0038] When the temple 31 is inserted into the slot 11, the protrusion 311 engages with the adjacent limiting hole 111. The temple 31 securely mounts the ear on the temple 31 by engaging the protrusion 311 with the limiting hole 111. Furthermore, by adjusting the number of protrusions 311 engaging with the limiting hole 111, the depth of the temple 31 inserted into the slot 11 can be adjusted, thereby achieving an adjustable effective length of the temple 31.
[0039] Example 3, please refer to Figures 5 and 6.
[0040] Based on the original embodiment 1, this embodiment preferably has a plurality of spaced limiting blocks 112 as the limiting part. In this embodiment, the plurality of limiting blocks 112 are preferably arranged in two rows, and the two rows of limiting blocks 112 are arranged symmetrically in the slot 11.
[0041] When the temple 31 is inserted into the slot 11, the upper and lower rows of limiting blocks 112 clamp the outer side of the temple 31. The limiting blocks 112 increase the friction between the inner wall of the slot 11 and the outer side of the temple 31, improving the firmness of the ear hook on the temple 31. In addition, the temple 31 does not need to be designed with a special structure to connect with the ear hook, so that the ear hook can be adapted to most of the existing temple 31s on the market.
[0042] This utility model provides an adjustable-size ear hook and eyeglass frame. The temples are inserted into slots in the main body, and the main body is more securely connected to the temples by a limiting part. When the user wears the glasses, the contact part hooks behind the wearer's ear, and the main body rests flat on the wearer's ear, thus forming restraint and support. When the temples need to be matched to users with smaller head sizes, by pushing the limiting part to slide in the groove, the limiting part is made to engage in a groove closer to the slot. The limiting part pulls the contact part and the temple end to elastically deform, shortening the distance between the frame and the contact part, and shortening the distance between the frame and the contact part. The effective length of the temples; when the temples need to be matched with users with larger head sizes, by pushing the limiting member to slide in the groove, the limiting member is made to engage in the groove closer to the tail. The limiting member pulls the contact part and the tail elastically deform, increasing the distance between the frame and the contact part, thus increasing the effective length of the temples. This allows the effective length of the temples to be adjusted according to the user's head size via the ear loops. There are multiple grooves in the groove, which can realize multi-level adjustment. In addition, the grooves can engage and constrain the limiting member in the current position, so that the frame and the contact part can maintain the current distance.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
