Further, since the manufacturing method is only molding, the cost is reduced.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Conventionally, a strap portion is made of a string, and it was not conventionally conceivable to form the strap by integral molding of plastic. In particular, an attachment member for attaching to a portable device has a small loop shape, and is a portion for forming a loop on an attachment portion of the portable device or the like and attaching it to the portable device or the like. And this attachment member must be rich in flexibility. The attachment member is made of a material that can expand and contract to a certain extent, and is preferably formed in a ring shape. According to the present invention, the connecting portion 3 to be attached to the mounting member 1 is formed of a flexible plastic resin, or only the connecting portion 3 is formed of a hard plastic resin and is formed so as to extend from the connecting portion 3. Thereby, the mounting member 1 satisfying the above requirements can be created. The strap 3 is attached to the connecting portion 3 and molded. Therefore, the strap portion 2 is preferably a loop-shaped strap belt, or a long molded body of a plastic resin having a cross section such as a circular cross section. In this case, a center core can be inserted for reinforcement and so as to obtain a certain degree of tension.

[0009] The strap portion 2 is preferably a loop-shaped strap belt, and is formed of an elastic plastic resin. In addition, by utilizing the elasticity of the molded plastic resin, an insertion opening shape 9 for fixing is provided, and a function as a scissor-shaped clip can be added. A portable device or the like can be suspended from the end of the device. It is also preferable to incorporate a leaf spring 13 inside the scissor-shaped clip 2.

The hand strap structure of the present invention is an integrally formed hand strap structure composed of two main members, namely, a member 1 for attaching to a suspended body such as a portable device formed of a small loop and a strap portion formed integrally. Body. The strap portion is a loop portion formed by a conventional hand strap in the form of a loop, that is, a loop portion to be hung on the hand when held by hand. That is, when a portable device or the like is held by the integrally formed hand strap structure of the present invention, it is held by hand, or
It is the part that fixes something.

The integral molded body used in the strap structure of the present invention, that is, the small loop portion 1 for attachment, the coupling portion 3 and the strap body 2 can be manufactured by integral molding of a plastic resin or rubber molded body. The plastic resin is
They must be flexible and do not use harmful plastics as they come into direct contact with the hand. Also,
Since the attachment member 1, the coupling portion 3, and the strap portion 2 must be integrally formed, the molding method must be devised. For example, one solution is to form the connecting part 3 and the strap part 2 from a hard plastic, and to form the small mounting loop part 1 from a soft plastic resin. In this case, plastic resins of different properties are used. In this case, it is necessary to use a molding technique of two-color molding.

Accordingly, as the plastic resin material used in the hand strap structure of the present invention, it is preferable to use a soft plastic resin especially as a molding material of the small loop mounting member 1. However, a hard plastic resin would be suitable for the joint. In addition, strap part 2
Also, a soft plastic resin is suitable. Therefore, in the hand strap structure of the present invention,
Although only a soft resin can be molded, if a soft resin and a hard resin must be formed, a special technique such as the two-color molding method is required as described above.

The connecting portion 3 can be formed into a scissor-like clip shape, or other functions can be added. Therefore, the coupling structure of the hand strap structure of the present invention can generally be a highly flexible mounting member, a coupling portion having a certain degree of rigidity, and a flexible strap portion.

The small loop-shaped attachment member portion 1 of the integrally formed hand strap of the present invention is formed of a soft resin, is sufficiently flexible, and can be easily attached to the attachment hole or the attachment rod of the device. Must be something. Also,
The strap portion 2 must be adapted to fit in the hand to be gripped by hand. Therefore, care must be taken in selecting the plastic resin used for molding.

Since the strap portion 2 is formed integrally with the connecting portion 3, it is preferable that the loop-shaped strap portion 2 is formed to extend from the connecting portion 3 as a base. The reason why the strap portion 2 is joined to the joining portion 3 is that the strap portion 2 is formed of a soft resin and the joining portion 3
However, in general, it can be made of a hard resin and can be carried out by the two-color molding technique as described above.

The strap portion 2 has a shape that can be gripped by hand, and therefore, a long belt-shaped or long object having a circular cross section is suitable. The small loop-shaped mounting member 1 is a part for fixing to a portable device, and can be changed in shape as such, and thus, can be formed into a convenient shape for fixing. For example, as shown in FIG. 3A, a mounting portion 1 having a mounting hole 5 and a strap portion 2 for gripping are formed, or a mounting portion 6 having a mounting ring 6 as shown in FIG. 3B. The part 1 and the strap part 2 are integrally formed.

Further, in the conventional strap structure, since the cord body and the strap part string were joined by welding or the like, the tensile strength was varied, and a product with insufficient strength was mixed. A molded hand strap structure is inherently stable in quality.

The portable equipment to which the integrally formed hand strap structure of the present invention is applied includes the above-mentioned portable telephone,
Not only small portable electric devices such as portable radios, portable televisions, small TV cameras, and cassette tape recorders, but also small portable devices such as cameras.

Hereinafter, an example of the integrally formed hand strap structure of the present invention will be described, but the present invention is not limited thereby.

Embodiment 1 FIGS. 1 (A) and 1 (B) are perspective views showing an integrally formed hand strap structure of the present invention. A small loop-shaped mounting member 1, a loop-shaped strap portion 2, and a connecting portion 3 for connecting them are formed by integral plastic resin molding. Generally, it is formed into a wide strap belt shape as shown in FIG. This must be flexible because the part of the mounting member 1 has to be mounted on a portable device.

FIG. 1B shows a slightly elongated attachment member 1 and a strap portion 2 having the same structure.
That is, the attachment member 1 has conventionally used a thin string for attachment. However, in the present invention, the attachment member 1 must be a thin plastic molded body as shown in the drawing so as to be attached to a portable device. And the strap part 2 is also a hand strap, so it is made a wide belt. Since the two have completely different sizes and possibly different properties, as shown in FIG.
Are combined using That is, in the present invention, the conventional hand strap is integrally formed of a plastic resin instead of the conventional attachment string and the hand strap portion.

Incidentally, the strap portion 2 can be formed into a round bar shape, and can be a long object having sufficient flexibility. Further, in the integrally formed hand strap structure of the present invention, the wide belt portion 2 of the strap portion may be provided with uneven stripes in the lateral direction to prevent slip.

Such an integrally formed hand strap structure of the present invention is used as shown in FIG. That is,
The attachment member 1 of the strap structure of the present invention is hooked on the attachment shaft 21 of the portable device 20, and the strap 2

[0024]

Second Embodiment The structure shown in the perspective view of FIG. This embodiment is shown in the schematic explanatory view of FIG. 2, in which the strap portion 2 of the plastic resin integrally molded portion is formed into a band-shaped loop 4 having an insertion opening 9. The mounting member 1 is
1 is the same as that of FIG. 1, except that the strap portion 2 has a wide band-like loop shape. An insertion port 9 is provided at the end of the wide band-shaped mounting member 1 side, and an edge of a pocket or the like can be inserted and gripped here.

That is, as shown in the figure, the strap portion 2
By making the insertion device 9 wide and having the insertion port 9 on the side of the attachment member 1, the force when the portable device or the like falls is applied in the direction opposite to the direction in which the portable device is pulled out.
It can be securely gripped and easy to use. In this embodiment, as shown in FIG. 2, the loop-shaped strap portion 2 of the plastic resin integral molding portion is not a simple loop but a loop shape. And the loop-shaped portion 4 is formed from a plastic resin rich in elasticity, and even if the gap 9 is widened by the elasticity, a force to return to the original state works.
The object sandwiched by the gap 9 is held by pressing. Therefore, it is convenient to use the portable device when holding it at the pocket end, the bag end, or something.

In order to assist the elasticity of the loop portion 4, it is preferable to incorporate a highly elastic metal plate therein. In the integrally formed hand strap structure shown in FIG. 2, a scissor-shaped clip shape is formed, and the loop-shaped portion 4 extends from one end of the strap portion 2.

Then, the clip shape 4 of the scissor shape is
Since it is formed and made of a material having high elasticity, the portable device can be hung on a pocket, a belt, or the like by the scissor-shaped clip 4. Also, even when it is put in a bag or the like, if the insertion opening 9 is hung somewhere on the inner surface of the bag, the loop-shaped portion 4 can be easily taken out by pulling it out. That is, a finger, a hand, and the like pass through the loop portion 4 and can be used as a handle. The loop portion 4 can be made smaller and a structure can be taken out with a finger. When the clip portion 4 is formed of a soft resin, a leaf spring may be incorporated therein to reinforce strength and elasticity.

[0028]

Third Embodiment A structure shown in the perspective views of FIGS. 3A and 3B, wherein a through hole 5 or a ring 6 engaged with the through hole 5 is used as a mounting member. One example is a schematic perspective view of FIG. 3A, and another example is shown in FIG. 3B.

[0030]

The hand strap structure of the present invention has the following technical effects by the structure shown in the drawing. That is, since it is constituted only by the integrally formed strap body, the manufacture of the hand strap structure can be simplified, the working efficiency can be improved, and a low-cost hand strap can be realized. In the conventional strap structure, since the string body and the strap part string were joined by welding or the like, the tensile strength varied, and insufficient strength was mixed, but in the hand strap structure of the present invention, Since the components are basically two components, the attachment member and the strap body, and they are simply formed by combining them, the quality is inherently stable. Furthermore, in the hand strap structure of the present invention, since the clip is provided with an insertion opening with an opening on the side of the attachment member, the falling force is in the opposite direction to the removal of the clip, so it is difficult for the hand strap structure to fall from the pocket opening or the like. You can get a hand strap. In addition, the hand strap structure of the present invention is an integrally molded body, so that it is not a string and a fixed part as in the past, but by devising a molding die, additional functions such as clips, etc. Can be added, and the degree of freedom in terms of design has been expanded, enabling the emergence of an excellently designed hand strap.
