Problems solved by technology

[0012] However, when many notches are formed in the socket, there is a problem that the strength against the above-mentioned deformation is lowered, and conversely, the thickness of the wall may need to be increased, which is not necessarily effective for weight reduction.

no. 1 Embodiment approach

[0050] Figure 1 to Figure 7 The first embodiment of the present invention is shown in .

[0051] Such as Figure 1 to Figure 3 As shown in each figure, the side release buckle 1 of this embodiment has a plug 10 and a socket 20 into which the plug 10 is inserted and engaged.

[0052] As shown in these respective figures, the side release buckle 1 of this embodiment is used to connect and separate the ends 2 and 3 of the rope-like members, and has a plug 10 integrally formed of synthetic resin and a socket similarly integrally formed of synthetic resin. 20. In addition, the material of the plug 10 and the socket 20 is not limited to synthetic resin, but may be other materials such as metal, and is not limited to injection molding, and may be formed by other molding methods.

[0053] exist figure 1 and figure 2 Among them, the plug 10 is integrally formed by injection molding of synthetic resin. The plug 10 has a base 11 and an engaging portion 14. The base 11 has a belt m...

no. 2 Embodiment approach

[0096] Figure 8 The second embodiment of the present invention is shown in .

[0097] The side release buckle 2 of this embodiment has the same plug 10 and socket 20 as those of the above-mentioned first embodiment. However, in this embodiment, the notch 25 on the side of the tape mounting portion 29 is formed on the receptacle 20, but the notch 28 as in the above-mentioned first embodiment is not formed (see figure 1 ), correspondingly, the concavo-convex shape 26 is formed continuously from the edge of the insertion opening 22 to be longer.

[0098] In this embodiment, there is no figure 1 Accordingly, it is not possible to reduce the material of the main body 21 or reduce the weight of the main body 21, but other than that, the same effects as those of the above-mentioned first embodiment can be obtained. Furthermore, by increasing the uneven shape 26, it is possible to increase the rigidity of the main body 21 compared to the first embodiment described above.

no. 3 Embodiment approach

[0100] Figure 9 The third embodiment of the present invention is shown in .

[0101] The side release buckle 3 of this embodiment has the same plug 10 and socket 20 as those of the above-mentioned first embodiment. However, in this embodiment, the notch 28 on the side of the insertion port 22 is formed on the socket 20, but the notch 25 like the above-mentioned first embodiment is not formed (refer to figure 1 ), correspondingly, the concavo-convex shape 26 is formed continuously from the edge of the belt mounting portion 29 to be longer.

[0102] In this embodiment, there is no figure 1 Accordingly, it is not possible to reduce the material of the main body 21 or reduce the weight of the main body 21, but other than that, the same effects as those of the above-mentioned first embodiment can be obtained. Furthermore, by increasing the uneven shape 26, it is possible to increase the rigidity of the main body 21 compared to the first embodiment described above.

Abstract

Disclosed is side release buckle including a plug (10) and a socket (20) into which the plug is inserted and engaged. The plug (10) has a base portion (11) that includes a belt fitting portion (19) and a pair of leg portions (12), and engaging portions (14) formed in each of the leg portions (12). The socket (20) has a main body (21) that includes a belt fitting portion (29) and an insert hole (22), a housing space (23) formed in the main body (21) and able to house the leg portions (12) inserted through the insert hole (22), and engaged portions (24) formed in the main body (21) with which the engaging portions (14) are able to engage. The main body (21) includes an undulation (26) provided continuously in the top side or bottom side thereof in at least the direction of insertion of either of the leg portions (12).

Description

technical field [0001] The present invention relates to a buckle for connecting straps to each other, namely a side release buckle having a pair of locking arms on both sides. Background technique [0002] Conventionally, a buckle for detachably engaging a plug and a receptacle has been used to connect string-like members such as belts to each other in various applications such as clothes, bags, shoes, and packages. [0003] In this kind of buckle, it is required that the operation for attaching and detaching is simple, and on the other hand, it is required not to accidentally disengage when it is not intended to be disengaged. As a product that complies with such a request, a side release buckle having a pair of locking arms on both sides is used. [0004] For example, the side release buckle of Patent Document 1 or Patent Document 2 is composed of a plug and a socket each having a belt mounting portion. [0005] The plug has a base having a strap mounting portion and a p...
