Headgear adjustment structure for swim goggles

Abstract

The headband adjusting structure of swimming goggles mainly comprises at least one adjusting member and a swimming band. The adjusting member comprises a connecting member, a fixed buckle and a positioning buckle arranged on opposite sides of the connecting member. A positioning hole is arranged in the middle of the positioning buckle. The positioning hole is formed with a tapered slope from the position where the positioning hole is connected with the fixed buckle and the connecting member to the inner wall of the two sides opposite to the other end connected with the connecting member. Two buckle teeth are arranged on the inner wall of the positioning hole adjacent to the positioning buckle. The side surface of the swimming band is provided with a plurality of convex portions, and a positioning groove is formed between each convex portion. The swimming band is arranged in the positioning hole. When the swimming band is pulled to be worn with the swimming goggles, the convex portion of the swimming band passes through the two buckle teeth. The two buckle teeth and the convex portion are forced to drive the two buckle teeth to be elastically deformed and move to the middle to generate a lateral force, so as to drive the tapered slopes of the two compression portions to compress the swimming band, and the swimming band is compressed and deformed into an arc state by the lateral force.

Description

Technical Field

[0001] This invention belongs to the field of sporting goods, and in particular relates to a headband adjustment structure for swimming goggles. Background Technology

[0002] Swimming goggles are worn by users while swimming. Their main purpose is to prevent water from coming into direct contact with the eyes, prevent eye pain caused by different tensions, allow users to see things in the water clearly, avoid allergies to disinfectants and the spread of diseases, and also prevent being accidentally hit or kicked in the eyes by other swimmers.

[0003] The main way to wear swimming goggles is to cover the user's eyes with the two frames of the goggles, and then tighten the headband to use the elasticity of the headband to fix the goggles to the user's head. In order to prevent them from coming loose while swimming, existing swimming belts have a stop to prevent them from slipping off when the belt is tightened. However, the presence of the stop also makes it difficult to pull when the belt is tightened, and may even cause the goggles to slip under the force, resulting in water entering the goggles while swimming.

[0004] To overcome the aforementioned problems, the invention patent "Swimming goggles and headband structure" (publication number TWI720807B) and the utility model patent "Headband adjustment device and swimming goggles" (publication number TWM454225U1) both improve the headband structure of swimming goggles. However, most of their improvements are still focused on adjusting the size of the buckle teeth, such as the tooth shape and angle. This results in a large friction force when the swim belt is pulled, causing the swimming goggles to slip under the force and even increasing the wear rate of the buckle teeth.

[0005] As mentioned above, the current adjustment structure of swimming goggles still has its problems and is not a good design. Therefore, the inventor of this project was eager to improve and innovate it. After painstaking research, he finally succeeded in developing the headband adjustment structure of this swimming goggle. Summary of the Invention

[0006] To address the known problems described in the prior art, the object of the present invention is to provide a headband adjustment structure for swimming goggles.

[0007] To achieve the above objectives, the swimming goggles headband adjustment structure provided by the present invention mainly includes an adjustment component and a swimming belt. The adjustment component includes a connecting part, a fixing buckle, and a positioning buckle. One end of the fixing buckle is connected to one side of the connecting part, and a through hole is provided in the middle of the fixing buckle. One end of the positioning buckle is connected to the other side of the connecting part opposite to the fixed buckle. A positioning hole is provided in the middle of the positioning buckle. The two sides of the positioning hole gradually taper from the end connected to the connecting part toward the free end of the positioning buckle to form an inclined surface. A buckle tooth is provided on the inner side of the positioning hole adjacent to the free end of the positioning buckle.

[0008] One side surface of the swim belt has multiple protrusions at both ends, and a positioning groove is formed between each of the protrusions. When the swim belt is inserted into the insertion hole and the positioning hole, the positioning groove accommodates the buckle teeth. When the swim belt is inserted into the positioning hole, the two sides of the swim belt are squeezed by the inclined surfaces on both sides of the positioning hole, generating a lateral force. As a result, the swim belt is deformed into an arc shape by the lateral force.

[0009] The fastener includes two extensions, one end of which is connected to one side of both ends of the connecting part. The free end of each extension extends toward the other extension and has a stop portion. The extensions and the stop portions surround the connecting part to form a through hole.

[0010] The positioning buckle includes two compression parts and two positioning parts. One end of each compression part is connected to one side of the connecting part, and the free ends of each compression part extend away from the connecting part. One end of each positioning part is connected to the free end of the two compression parts, and the free ends of the two positioning parts extend toward the other positioning part.

[0011] The two stop parts are connected to each other or have an opening, and the two positioning parts have a gap. Attached Figure Description

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0016] like Figures 1-4 As shown, the headband adjustment structure of the swimming goggles provided by the present invention mainly includes two adjustment components 1 and a swimming belt 2. Each of the two adjustment components 1 includes a connecting part 11, a positioning buckle 12 and a fixing buckle 13. The positioning buckle 12 and the fixing buckle 13 are located on opposite sides of the connecting part 11 and connected to the connecting part 11. The fixing buckle 13 includes two extensions 131. One end of each of the two extensions 131 is connected to the side of one of the two ends of the connecting part 11. The other end of each extension 131 connected to the connecting part 11 has a stop part 132. Both stop parts 132 extend toward the other connecting part 11, so that the fixing buckle 13 forms a through hole 133 through the middle of the fixing buckle 13 by the connecting part 11, the two extensions 131 and the two stop parts 132.

[0017] The positioning buckle 12 includes two compression portions 121 and two positioning portions 122. One end of each of the two compression portions 121 is connected to the side of one of the two ends of the connecting portion 11. The other side of each compression portion 121 connected to the connecting portion 11 extends towards the other compression portion 121 to form a positioning portion 122. A positioning hole 123 is formed by the two compression portions 121, the two positioning portions 122 and the connecting portion 11. The positioning hole 123 has a slope 1211 on its inner wall surface, which gradually narrows from the end where the two compression portions 121 are connected to the connecting portion 11 towards the two positioning portions 122. In addition, there is a gap 124 between the two positioning portions 122. Each of the two positioning portions 122 has a buckle tooth 125 on its surface facing the inside of the positioning hole 123.

[0018] Each end of the swim belt 2 is provided with a fixing member 21. Each fixing member 21 includes two clamping parts 211 and a through part 212. The through part 212 is located between the two clamping parts 211. One side surface of the swim belt 2 has a plurality of protrusions 22. A positioning groove 23 is formed between each protrusion 22.

[0019] When the headband adjustment structure of the swimming goggles provided by the present invention is assembled, the two ends of the swimming belt 2 correspond to an adjustment member 1 respectively. Each end of the swimming belt 2 passes through the positioning hole 123 of the positioning buckle 12 in the adjustment member 1, and the swimming belt 2 with a plurality of positioning grooves 23 faces the buckle teeth 125 in the positioning hole 123. The buckle teeth 125 are accommodated by one of the positioning grooves 23 on the side of the swimming belt 2. Then, the through part 212 of the swimming belt 2 is inserted into the through hole 133 of the fixing buckle 13, and the top and bottom surfaces of the periphery of the through hole 133 are clamped by two clamping parts 211, so that the fixing member 21 of the swimming belt 2 clamps the fixing buckle 13.

[0020] The headband adjustment structure of the swimming goggles provided by this invention adjusts the length of the swimming belt 2 by pulling it, in conjunction with a reference. Figure 5 As shown, when the swim belt 2 is pulled, when the protrusion 22 of the swim belt 2 passes through the two buckle teeth 125 of the positioning buckle 12, the two buckle teeth 125 and the protrusion 22 are subjected to force, causing the two buckle teeth 125 to move towards the middle due to elastic deformation, thereby generating a lateral force (stress). This causes the inclined surface 1211 of the two compression parts 121 to press against the swim belt 2, so that the swim belt 2 is subjected to a lateral force (such as... Figure 6 As shown, the swim belt 2 is compressed and deformed into an arc shape, wherein the swim belt 2 is compressed and deformed into an arc shape by lateral force.

[0021] When the swim belt 2 is compressed and deformed into an arc shape by lateral force, the protrusion 22 on the swim belt 2 also bends into an arc shape as the swim belt 2 deforms. As a result, the protrusion 22 reduces the contact area with the buckle 125 due to the deformation, so that the swim belt 2 can quickly pass through the positioning hole 123 and reduce the probability of wear between the buckle 125 and the protrusion 22.

[0022] In summary, this invention is completely novel, with no similar inventions disclosed or filed prior to it in the market, and has industrial applicability with substantial improvements in efficacy. Therefore, a patent application is filed in accordance with the law. However, this specification is only a description of preferred embodiments and is not intended to define the scope of the patent. All modifications and variations made to the constituent elements under the principles and technology of this invention should be covered within the patent scope of this invention.
