Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing button technology, and in particular to a button extender. Background Technology
[0002] Buttons are a type of accessory used to fasten clothing. In daily life, buttons are sewn onto clothing, and the distance between the button and the buttonhole is fixed. When people gain weight, their waist, arms, and neck will inevitably grow, causing pants to become too small, collars to be too tight, and cuffs to be too heavy.
[0003] In response, button extenders have been introduced on the market. These devices can extend buttons and fasten them into buttonholes, replacing the original buttons on clothing. When used, they can extend the original waistband, collar, and cuffs, allowing the original pants to be worn again after adjustment.
[0004] For example, patent document CN211431184U discloses an extension button, which belongs to the field of clothing button technology. It solves the problem that buttons cannot be fastened at the waist, arms, and neck after weight gain, making the clothing unwearable. Its key technical points are: it includes a button body and a rubber strip. The button body is connected to the rubber strip, which is clipped onto the button body. The rubber strip is provided with an extension hole. The rubber strip is fastened to the original button on the clothing. The button connected to the rubber strip replaces the original button on the clothing and connects to the original button hole on the clothing, realizing the extension of the waistband, cuffs, and collar of the clothing. The operation is convenient and quick.
[0005] The aforementioned extended button has a complex structure and high production cost, which is not conducive to its widespread use.
[0006] Therefore, improvements are needed. Utility Model Content
[0007] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a button extender to solve the problems mentioned in the background art.
[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a button extender, comprising: a button body, wherein the button body has at least two or more holes; an elastic cord, wherein the elastic cord passes through the holes and forms a loop with the button body.
[0009] Furthermore, the button body has four holes arranged in a circle; the elastic cord is crossed and connected to the holes on the front side of the button body, and the elastic cord forms a loop on the back side of the button body.
[0010] Furthermore, the button body has four holes arranged in a circle; the elastic cord is connected in parallel to the holes on the front side of the button body, and the elastic cord forms a loop on the back side of the button body.
[0011] Furthermore, after the elastic cord passes through the hole in the button body, the elastic cord is connected with glue to form a closed loop.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] Structural optimization effect: The multi-hole design, combined with the cross-connection of elastic cords, forms a stable stress structure. The resulting ring structure is used to connect buttons, making the structure simpler, reducing production costs, and making it more suitable for widespread use.
[0014] Convenient production: After the elastic cord is threaded through the hole in the button body, it is connected with glue to form a closed loop, which is convenient for production. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.
[0021] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application 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, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0022] In view of the technical problems described in the background art, as shown in the figure, a button extender is provided, comprising: a button body 1, wherein the button body 1 has at least two or more holes 2; and an elastic cord 3, wherein the elastic cord 3 passes through the holes 2 and forms a loop 4 with the button body 1.
[0023] In the above technical solution, two or four holes 2 are provided on the button body 1 to facilitate the insertion and withdrawal of the elastic cord 3.
[0024] When using two holes 2, the strip-shaped elastic cord 3 is inserted into the two holes 2 in sequence, and then the elastic cord 3 is connected with strong glue to form a closed loop structure. The strong glue must meet the connection strength of the elastic cord 3. The elastic cord 3 forming the closed loop structure forms a ring 4 on the button body 1. The ring 4 is used to connect with the button on the clothing, thereby realizing the extended use of the button.
[0025] When using four holes 2, the button body 1 has four holes 2 arranged in a circle. A strip of elastic cord 3 is connected to the four holes 2 on the front of the button body 1 in a crisscross or parallel manner. The two ends of the elastic cord 3 are then glued together to form a closed loop. One end of the closed loop is then passed through the elastic cord 3 within the closed loop of the button body 1, forming a protruding ring 4. The closed loop at the button body 1 is used to fix the elastic cord 3, thus securing the elastic cord 3 at the position of the ring 4 extending from the button body 1.
[0026] In the above technical solution, the multi-hole design 2 is used in conjunction with the cross-connection of elastic cord 3 to form a stable force-bearing structure. The resulting ring structure 4 is used to connect the button. The structure is simpler, reduces the manufacturing cost, and is more suitable for widespread use. After the elastic cord 3 passes through the hole 2 of the button body 1, the elastic cord 3 is connected with glue to form a closed loop, which is convenient for production.
[0027] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
