[0002]

2. Description of the Related Art With the progress of miniaturization of portable items such as mobile phones, it is difficult to connect such a combined strap to a portable item such as a large-diameter (thick diameter, wide) strap. On the contrary, if the whole is made of a small-diameter (small-diameter, narrow) strap, it has recently been widely used because it cannot provide a sense of stability and security when gripped.

[0003] Conventionally, this combination strap is generally formed by looping a hand strap (neck strap) which is a part to be held on a hand or a part to be hung on a neck.
It has a basic structure in which a small-diameter strap is inserted into the loop to form a loop, and the connection between the loops is fixed by cap molding. However, conventional products
Bonding work is required to make the hand strap and the small-diameter strap into loops, respectively, and the connection between the two straps is fixed by forming the cap mold, which is costly and it is difficult to reduce the size of the cap mold. Was. Further, there is a problem that it is difficult to obtain sufficient strength.

[0004]

An object of the present invention is to obtain such a combination strap inexpensively, with sufficient strength and with a small cap mold.

[0005]

SUMMARY OF THE INVENTION A combination strap according to the present invention is a hand strap formed into a loop with through holes formed at both ends thereof being overlapped with each other. A small-diameter strap in which loops are tied together to form a loop, wherein the strap is stored in a through-hole in which the binding portion is stacked; and a small-diameter strap which is stored in the stacked through-hole of a hand strap and the stacked through-hole. And a cap mold that covers the outside of the strap with the binding part and is adhered to the hand strap and the small diameter strap. Hand strap, both ends
By forming a groove for accommodating the two small diameter straps from the binding portion from the through hole of the portion to the end, the cap mold can be further reduced in size.

Further, in the manufacturing method of the present invention, a step of forming through holes at both ends of a series of hand straps; inserting a series of small diameter straps over the through holes at both ends of the hand belt. Bundling both ends of the inserted small-diameter strap into a loop; stacking through-holes at both ends of the hand strap and positioning the binding portion of the small-diameter strap in the overlapped through-hole; Covering the outside of the through hole and the binding portion of the small-diameter strap housed in the overlapped through hole with a cap mold and bonding them. It is desirable that the manufacturing method of the present invention further includes a step of forming, at both ends of the hand strap, storage grooves for the small-diameter strap from the respective through holes to the ends. In the step of positioning the binding portion of the small-diameter strap in the overlapped through-hole of the hand strap, the small-diameter strap is stored in the storage groove, and a cap mold is put on in this state.

[0007] Both ends of the small diameter strap can be bound by a binding metal fitting, or more simply by a knot. As the hand strap, either a round string strap or a flat string belt can be used, but a flat string belt has an advantage that formation of a through hole and further a storage groove is relatively easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiment is an example in which a flat string belt 10 is used as a hand strap. As shown in FIG. 1, through holes 11 are formed at both ends of a series of flat string belts 10.
Is pierced. Desirably, the through-hole 11 is subjected to a fraying prevention process. The flat cord belt 10 is generally made of a synthetic resin material, and the synthetic resin material can prevent the peripheral edge of the through hole from fraying by heat treatment.

A series of small-diameter straps 20 are inserted into the through-holes 11 of the flat-belt belt 10, and both ends of the strap 20 are bound by a binding metal 22 as shown in FIG. .

[0010] Next, as shown in FIG. 3, the narrow strap 20 having the binding portion 21 (the binding metal fitting 22) stores the binding portion 21 in the stacked through-holes 11 of the flat string belt 10. That is, both ends of the flat string belt 10 are
Are bound so as to match, and the binding portion 21 is housed in the overlapping through hole 11.

At both ends of the superimposed flat string belt 10,
The cap mold 30 is mounted so as to cover the through hole 11 and the binding portion 21 housed therein, and is bonded via an adhesive 33. The cap mold 30 is separately formed in advance and has a cap shape having one end opened and a bottom 31 provided at the other end. The bottom 31 has an insertion hole through which two small-diameter straps 20 can be inserted. 32 are formed.

The shape of the cap mold 30 is such that it can be attached to the end of the superimposed flat cord belt 10, can cover the binding portion 21 housed in the through hole 11 in the attached state, and With the adhesive 33 inserted into the inside, the cap mold 30 and the flat string belt 1
0 and that the small-diameter strap 20 is adhered.

The combination strap having the above structure is shown in FIG.
In the completed state of FIG. 5, the flat string belt 10 is formed into a loop in a state where the through holes 11 formed at both ends are overlapped; the flat string belt 10 is inserted over the through holes 11 at both ends of the flat string belt 10,
Narrow strap 2 with both ends bound and looped
0, the small-diameter strap 20 accommodated in the through-hole 11 in which the binding portion 21 is overlapped; and the small-diameter strap 20 accommodated in the overlapped through-hole 11 of the flat string belt 10 and the overlapped through-hole 11. A cap mold 30 that covers the outside of the binding portion 21 and is adhered to the flat string belt 10 and the small-diameter strap 20.

According to this combination strap, the loop of the flat string belt 10 is ensured by the small diameter strap 20 inserted into the through holes 11 at both ends of the belt 10. The loop of the small-diameter strap 20 is primarily obtained by the binding portion 21 (the binding metal fitting 22), and furthermore, the binding portion 21
Is accommodated in the through hole 11 of the flat string belt 10 and is guaranteed by being adhered by the cap mold 30.
Even with a small size, sufficient strength can be obtained. Further, since no adhesive is used to make the flat string belt 10 and the narrow strap 20 into a loop shape, the cost is low and the productivity is high. Furthermore, since the cap mold 30 may have any shape as long as it can cover both ends of the flat string belt 10, a combination strap with a small cap mold 30 can be obtained.

FIGS. 6 and 7 show another example of forming the binding portion 21 of the small-diameter strap 20. FIG. FIG. 6 shows an example in which both ends of the small-diameter strap 20 are folded back, and a pair of folded parts are bound by a binding metal fitting 22. FIG.
Is shown. In the example of FIGS. 2 and 6 using the binding metal 22, in order to increase the binding strength of the small-diameter strap 20, the binding metal 22 is moved in a direction orthogonal to the length direction of the small-diameter strap 20 as shown by a broken line 24. It is also possible to crush.
