Description

[Detailed description of the invention] "Field of industrial application" The present invention relates to an improvement of a shoulder strap for carrying bags, radios, tape recorders, cameras, etc. on the shoulder, and particularly relates to an improvement of a removable shoulder strap. It is something.

``Prior Art'' Conventionally, various configurations have been proposed for this type of shoulder strap, and a typical one uses a locking fitting 30 called an aubergine ring, which has an aubergine-shaped cross section as shown in FIG. (hereinafter referred to as the first conventional example of operation) is known, and as a simple structure, one using a drum-shaped connecting fitting 40 shown in FIG. 8 (hereinafter referred to as the second conventional example) is known. There is.

That is, in the first conventional example, locking metal fittings 30, 30 are arranged at both ends of the shoulder band main body 1, and the hook portion 31 of the locking metal fitting 30 is moored to the band attachment ring 4 of the object to be hung. In the second conventional example, the tip of the shoulder band main body 1 is folded back through the band attachment ring 4 of the object to be hung.
Slits 41, 4 arranged at appropriate intervals in the longitudinal direction of the
The connecting fittings 40 are passed through a pair of fittings 1, 41, .

``Problems that the invention attempts to solve'' However, the first conventional example above is based on the shoulder band body 1.
The locking metal fittings 30, 30 are interposed between the band body 1 and the object to be hung, and a sense of design unity between the band main body 1 and the object to be hung cannot be expressed, and the conspicuous locking metal fittings 30, 30 are This often has an undesirable effect on the design expression of objects, and furthermore, if the hard locking metal fittings 30, 30 are located close to the suspended object, there is a risk of damaging the suspended object during use. The shortcomings of doing so have been pointed out.

Furthermore, compared to the first conventional example, the second conventional example described above has the following characteristics:
It has the advantage of being simple and unobtrusive, and there is no risk of damaging the hanging object due to contact with the locking metal fittings, but the shape of the shoulder band main body 1 is limited to a thin flat belt shape, and the shoulder band main body 1 is limited to a thin flat belt shape, and the shoulder band main body 1 has a round cross section or the like. However, it has the disadvantage that it is difficult to implement.

Therefore, in view of the above-mentioned drawbacks, the present invention aims to provide a shoulder band that can express a design that has a sense of unity with the suspended object, and that can be easily manufactured even if the cross-sectional shape of the shoulder band main body is a desired shape. This is the purpose.

``Means for Solving the Problems'' In line with the above-mentioned purpose, the structure of the present invention, which is summarized in the above-mentioned claims for utility model registration, is to solve the above-mentioned problems by changing the outer periphery of both ends of the shoulder band main body 1. They are fastened with metal bands 2, and further, synthetic resin bases 11, 11 are encapsulated and molded at both ends of the shoulder band main body 1 including the metal bands 2, and the tips of the synthetic resin bases 11, 11 are is a flexible tongue piece 12
are integrally protruding from each other, and a technical measure is taken in which mutually attachable and detachable engaging portions 13a and 13b are arranged at the base and the folded portion on the distal end side of the flexible tongue portion 12. It is.

``Function'' Therefore, as shown in FIG. 1, in the shoulder band of the present invention, the tip of the flexible tongue portion 12 is folded back through the band attachment ring 4 placed on the object M to be hung, and the flexible tongue portion is folded back. The base of 12 and the folded part on the distal end side are connected to the engaging part 1
When engaged at 3a and 13b, the shoulder band main body 1 can be attached to the hanging object M, and the hanging object M can be hung by hanging the shoulder band main body 1 on the shoulder in the state shown in FIG. It is.

In addition, if the material of the shoulder band body 1 of the metal band 2 has elasticity, this elasticity is locally removed and the diameter is reduced due to the force applied in the stretching direction, so that the tip of the shoulder band body 1 is made of synthetic resin. It prevents the hard metal band 2 from slipping out of the synthetic resin base 11, and when the hard metal band 2 is wrapped around the synthetic resin base 11, it is held in a predetermined position by a receiving pin or the like in the mold (see Fig. 5). It acts so that it is fixed in place.

``Example'' Next, an example of the present invention will be described below with reference to FIGS. 1 to 6.

In the figure, M is a hanging object such as a bag, radio, tape recorder, camera, etc., and 1 is a band body from which the hanging object M is hung.

In the present invention, the band main body 1 can have an appropriate cross-sectional shape, and in the illustrated example, a round cross-section string made of fiber is used, but it is of course possible to use a flat band, a leather band, etc. , this band body 1
It is desirable to use a heat-resistant material for both ends of the base member 11, as they will be heated when enclosing and molding the synthetic resin bases 11, 11, which will be described later.

The outer peripheries of both ends of the shoulder band body 1 are fastened with metal bands 2, respectively. This metal band 2 is wound around and fastened around the outer periphery of the tip of the band body 1, and in this embodiment, as most clearly shown in FIG. A hook hole 23 is bored in the bottom portion of the gutter portion 22. This hooking hole 23 is provided with a pin 52 (this pin 52 is different from the mold body 51) which is protruded into the mold 50 shown in FIG. The metal band 2 may be configured separately so that it can be moved in and out of the hollow part into which the raw material synthetic resin is injected. A similar receiving pin 53 is arranged, and the pin 52 is inserted into the hooking hole 23 of the metal band 2 which is fastened to the band body 1, and one end side of the band body 1 protrudes from the mold 50. When pulled to the right in FIG. 5, the metal band 2 can be positioned in the left-right direction with respect to the mold 50,
In this state, when the upper mold (not shown in FIG. 5) is stacked on the mold 50, the metal band 2 is clamped and fixed from above and below between the receiving pin 53 and a receiving pin (not shown) opposite to the receiving pin 53 of the upper mold. I'm starting to do that.

Further, synthetic resin bases 11, 11 are encased and molded at both ends of the shoulder band main body 1 including the metal band 2. This synthetic resin base 11,1
1 is molded by injection molding using the mold 50 described above. In addition, if a heat-resistant bushing 16 is fitted over the band body 1 to the rear end of the metal band 2 prior to encasing and molding the synthetic resin bases 11, 11, the synthetic resin bases 11, 11 will be covered. It becomes difficult to transmit the heat during molding to the band body 1, and the band body 1
It is also possible to use materials with low heat resistance. Note that even if the synthetic resin bases 11, 11 only cover both ends of the shoulder band body 1 including the metal band 2, the connection between the synthetic resin bases 11, 11 and both ends of the band body 1 is strong. Although the band main body 1 will not come off from the synthetic resin bases 11, 11, a part of the metal band 2 mentioned above may be crushed to form a deformed part 24 (see Fig. 4), or both sides of the gutter part 22 may be crushed. By making the interval gradually smaller toward the tip, it is possible to more reliably prevent the band main body 1 from falling off from the synthetic resin base 11. When the bush 16 is fitted, a protrusion is provided on the outer periphery of the bush 16, or a flange-like protrusion 25 is provided on the outer periphery of the metal band 2 as shown in FIG. It is preferable that the portion 16a is locked by the protruding portion 25 to prevent it from falling off.

A flexible tongue portion 12 is integrally provided at the tip of the synthetic resin base portions 11, 11, respectively, and the base portion and the folded portion on the tip side of the flexible tongue portion 12 are mutually connected. Detachable engaging portions 13a and 13b are arranged. In the illustrated example, the engaging portion 13a on one side is connected to the flexible tongue portion 13a, 13b.
Although the engaging portion 13b on the other side is formed as a slit with an opening, the positions of the two may be reversed or both the engaging portions 13a and 13b may be formed as slits. Second conventional example connecting fitting 40
Alternatively, as shown in FIG. 6, the engaging part 13a on one side may be an inverted T-shaped slit and the engaging part 13b on the other side may be a tip with a constricted part. Although not shown, a conventionally known engaging member such as a hook may be provided. In addition, when disposing this engagement tool, it is necessary for the tip of the flexible tongue piece 12 to pass through the band attachment ring 4, and for this purpose, one side is attached to the tip side of the flexible tongue piece 12. It is desirable to arrange the buckle only at the base without providing any engagement tool.

In addition, in the figure, 14 is a hole to be made by a pin 52, 15 is a hole to be made by a receiving pin 53, 17 is a bellows part that facilitates bending of the flexible tongue portion 12, 5
Reference numeral 4 designates a slide mold part into which the protruding engaging part 13a is fitted into the locking hole 14.

[Effect of the invention] Since the present invention is as described above, the flexible tongue portion 12 can be integrally connected to the band main body 1 having a desired cross-sectional shape via the synthetic resin base 11, and the band main body 1 It is possible to easily use the members of the present invention, which were conventionally considered unsuitable for string-like materials, and to provide a shoulder band in which the members of the band body 1 can be widely used.

In addition, a synthetic resin base 11 and a flexible tongue portion 12 are also provided.
It has appropriate elasticity and can be manufactured compactly and strongly, so it does not interfere with the design, and there is little risk of damaging the suspended object M due to contact. Since the flexible tongue part 12 can be freely colored and selected in shape, it is possible to provide a shoulder band that can achieve a wide sense of design unity between the band body 1 and the hanging object M.

Furthermore, since the members of the band body 1 can be used in a wider range than conventional band body members, a reduction in the material cost of the band body 1 can be expected. Since it is integrally molded into the band main body 1 in an industrial production process, it is possible to provide an inexpensive shoulder band suitable for mass production.
