Problems solved by technology

Therefore, in the frequently used swivel position, for example, in the case of a snap hook for a shoulder bag, when the holding members 50, 70 and the hook main body 60 are in an orthogonal state, some external force can be applied to easily make the enlarged portion 63 is pulled out from the embedded holes 53 and 73, resulting in the problem that the spring hook cannot be used

Embodiment 1

[0043] Figure 1-8 The connector of the shown embodiment 1 is as described above, the first member 1 of the connector is formed by the belt connecting member 4, the second member 2 is formed by the spring hook 5, and the two members 4, 5 use thermoplastic resin injection molding to prevent Take off the whole outside the sheet 28. Although the fall-off preventing piece 28 is formed of a wire, the same resin as the spring hook 5 may be used to integrally form one fall-off preventing piece 28 on the back surface of the base 20 . The hook portion 26 of the spring hook 5 projects a hook portion 26 of a T-shaped section on the back side of the circular abutment 20, forms a reinforcement portion of the same width on the outside of the hook portion 26, and forms a reinforcement portion of the same thickness on the inside. hook. In addition, on the back side of the base 20, a short-sized support part 25 is provided in the form of being provided with the hook part 26 together, and two...

Embodiment 2

[0049] Figure 9 The connector of the illustrated embodiment 2 is such that the form of the locking portion 23 of the enlarged portion 22 of the above-mentioned embodiment 1 is changed from image 3 In the state where the shown form is staggered by 90 degrees, the direction of the main body 19 of the spring hook 5, that is, the locking portion 23 of the enlarged portion 22 in the same direction as the hooking direction of the hook portion 26 can be set as the minor axis S′, and The locking portion 23 of the enlarged portion 22 in the direction perpendicular to the direction of the hook portion 26 is the major axis L′. Other constitutions are the same as the previous example. The use form of the snap hook 5 in this case is suitable for an implementation form with a phase difference of 90 degrees from that of the first embodiment described above.

Embodiment 3

[0051] Figure 10 The connector of the shown embodiment 3 is provided in the outlet side form of the embedded hole 13 of the belt support rod 11 expansion part 12 in the belt connection member 4 and the form of the expansion part 22 of the spring hook 5 is different from the structure of the above-mentioned embodiment 1. The locked portion 15 provided on the exit side of the fitting hole 13 of the expansion portion 12 of the belt support rod 11, that is, the major axis L and the minor axis S are as follows in the above-mentioned embodiment 1. figure 2 , 3 As shown, the major axis L of the fitting hole 13 and the major axis L' of the enlarged portion 22 are formed to have the same length, but in Embodiment 3, the oblate circle (including the ellipse) formed by the major axis L and the minor axis S ) to form the embedding hole 13, the enlarged part 22 of the spring hook 5 is formed by the major axis L' and the minor axis S' which are larger than the major axis L and the minor ...

Abstract

To connect a belt connecting member ( 4 ) of a first member ( 1 ) with a snap hook ( 5 ) of a second member ( 2 ), a neck portion ( 21 ) having a circular cross section is provided so as to project from a connecting portion of the snap hook ( 5 ), a bulging portion ( 22 ) is provided on a tip end of the neck portion ( 21 ) so as to radially bulge to define an engaging portion ( 23 ), a fitting hole ( 13 ) is provided on a connecting portion of the belt connecting member ( 4 ) with an engaged portion ( 15 ) that is engageable with the bulging portion ( 22 ), the engaged portion ( 15 ) and the engaging portion ( 23 ) are formed in an oval shape having a long axis (L, L') in a flush plane of the belt connecting member ( 4 ) and the snap hook ( 5 ) and a short axis (S, S') in orthogonal planesof the belt connecting member ( 4 ) and the snap hook ( 5 ), and the engaging force can be largest when the snap hook ( 5 ) is in its most general state in use where the belt connecting member ( 4 )and the snap hook ( 5 ) are orthogonal.

Description

technical field [0001] The present invention relates to a synthetic resin snap hook (Snap hook) or connecting piece; the snap hook is inserted through the strap of a shoulder bag, backpack, etc. Connection; the connecting piece is rotatably mounted to the belt mounting member disposed at one end of the insert body in the insertion type buckle, or is freely rotatably connected to the belt mounting member for connecting the left and right belts themselves. [0002] The present invention relates to a joint comprising two members freely rotatably connected. As the connector, it is a spring hook made of synthetic resin, or a connector in which a belt attachment member is rotatably attached to one end of the insert body in an insertion type buckle, or is rotatably connected to connect the left and right belts themselves. A pair of connectors with mounting components, etc.; the spring hook is inserted through the belt of a shoulder bag, backpack, etc. on one side, and can easily han...
