[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a belt connector that can be freely engaged and disengaged, such as when a shoulder belt of a shoulder bag is hooked on a connecting ring provided on the bag.

[0002]

[Prior art]

 It is required that the belt connecting device of the shoulder bag can be freely attached and detached, and that it can be freely rotated to restore the twist of the belt. In response to this request, conventionally, there has been provided a connecting device generally called "Eggplant ring". Some eggplant rings are made of metal, but recently, many eggplant rings made of synthetic resin have been provided because of their excellent moldability and mass production. As shown in FIGS. 5 and 6, the connecting device of the eggplant ring type has an annular connecting main body 1 to be attached to a belt, and is rotatably assembled to the connecting main body to be connected to an object such as a bag. It is generally composed of a hook member 2 that can be freely attached and detached, and both of these members are made of synthetic resin separately, and then they are joined together to complete the structure. It is normal. More specifically, referring to the drawings, in the conventional connecting tool, a connecting main body 1 formed in an annular shape is provided with a cylindrical connecting tubular portion 3 and an annular locking portion 4 is provided on an inner wall surface of the connecting tubular portion, while a hook member is provided. 2 is provided with a hemispherical fitting portion 5, and a neck portion 6 and a hook portion 8 having a folded back engaging portion at the tip end thereof are integrally provided on the fitting portion and these two portions are integrally formed. Is formed as a separate body, and then the fitting portion 5 of the hook member 2 is made to face the cylindrical connecting cylindrical portion 3 of the connecting main body 1 from below (the outer side when the connecting main body is an annular body). By forcibly penetrating the hole 9 that opens in the center of the stopper 4, both members are joined together to complete the process.

[0003]

[Problems to be solved by the device]

 The connecting tool assembled as described above is inserted into the hole 9 through the neck portion 6 to engage the fitting portion 5 with the locking portion 4 so that they can be joined together without being easily separated, and a hook member can be attached to the connecting body 1. Since 2 is assembled so that it can rotate freely, it fulfills the function required for this kind of connecting tool, but one drawback is that the connecting force of the hook member to the connecting body is uneasy. Is. That is, the two are coupled by forcibly inserting the fitting portion 5 of the hook member through the hole 9 of the locking portion 4, so that when a stronger force acts in the pulling direction, the locking portion 4 bends in the opposite direction. There is a risk that the holes 9 will expand and fall out. This defect can be eliminated by strengthening the locking portion 4 or making the diameter of the fitting portion 5 large to make it difficult to come out of the hole 9, but this method makes the joining work difficult. That is not an effective solution. The present invention has been devised in order to improve the situation in view of such a situation, and in particular, the present invention facilitates the combination of the connecting main body and the hook member to improve workability, and at the same time, combines the two bodies. An object of the present invention is to provide a synthetic resin belt connector having an eggplant ring shape, which has a high bonding strength afterwards and is excellent in productivity and has high reliability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 of the accompanying drawings is a front view of a connector according to the present invention in a completed assembled state, FIG. 2 is a partially cutaway front view of a disassembled state, and FIG. 3 is a fully assembled state. FIG. 4 is a plan view of the connecting main body. In these drawings, reference numeral 11 indicates a connecting main body, and 12 indicates a hook member.

The connecting main body 11 is directly attached to a belt of a shoulder bag or the like, and is formed in an annular shape through which the belt is passed. The upper edge portion 11b is notched in the central portion thereof to form a belt insertion opening 13. The hollow portion of the connecting main body serves as an insertion space 14 through which the belt is passed, and the length in the lateral direction is formed according to the width of the belt passed therethrough. The belt may be inserted into the insertion space 14 from its end, but here, one side edge of the length of the belt is inserted into the insertion port 13 and is inserted into one end of the insertion space 14. Later, the other side edge will be inserted by pulling it into the other end of the space.

A connecting recess 15 for connecting the hook member 12 is formed at the center of the lower edge 11a formed in the shape of a wide plate. The connecting recess is formed in a substantially cylindrical shape, the hollow interior 16 is formed in a hemispherical shape, and the opening 17 facing the insertion space 14 is formed in a circular shape. The opening facing outward is reduced in diameter to form the bottom portion 18, and the insertion hole 19 is provided through the center of the bottom portion. On the other hand, a plurality of small projections 20 are arranged at equal intervals along the circumferential direction on the inner peripheral surface of the insertion space 14 facing the opening 17 to provide a substantially reduced diameter portion.

The hook member 12 is composed of a spherical connecting portion 21 and a hook portion 23 which is derived from the connecting portion and has a locking portion 22 provided at the tip thereof. The piece 24 is derived. The connecting portion 21 is formed in a spherical shape having a diameter that can be accommodated in the connecting concave portion 15 of the connecting main body, and the hook portion 23 includes an auxiliary piece 24 so that the hook portion 23 can be easily inserted into the insertion hole 19 of the connecting concave portion in a normal state. To form.

The connecting main body 11 and the hook member 12 are formed by individually forming a thermoplastic synthetic resin having appropriate rigidity and elasticity, such as polyacetal, as a material, and then connecting the both to form a finished product. Next, this assembly will be described. With respect to the independently molded connecting main body 11, as shown in FIG. 2, the hook member 12 is exposed from above and the hook portion 23 is inserted into the connecting concave portion 15 through the insertion hole 13. Then, the hook portion 23 is passed through the insertion hole 19 and the spherical connecting portion 21 is fitted into the inner portion 16 having a hemispherical cavity shape to complete the connection between the two.

The insertion opening 13 is located directly above the opening 17 of the connection recess 15 to help the hook portion 23 stick in and prevent the connection portion 21 from passing therethrough. The notch is formed to be larger than the diameter of.

The connecting portion 21 fitted into the connecting concave portion 15 bends the small projection 20 and expands the reduced diameter portion formed by the small projection to enter the inside 16 and abut the bottom portion 18. As the small protrusions are restored at the time of rolling, they will be fitted in a state in which they are prevented from coming out. The connecting portion 21 housed inside the connecting concave portion is slidably engaged with the bottom portion 18 to freely rotate, and the hanging hook portion 23 can be swung with the connecting portion 21 as a fulcrum within the range of the insertion hole 19. It will be possible.
