Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a strap for a mobile phone device.

[0002]

[Prior art]

 In recent years, the number of users of mobile phone devices has increased rapidly, and it has been used by people of various ages regardless of gender. Conventionally, in such a mobile phone device, when the mobile phone device is held, the strap is held using a strap.

[0003]

[Problems to be solved by the invention]

 There are various types of the above-mentioned straps, such as short straps for holding on hand and long straps for hanging down the neck for the purpose of hanging from the neck. Users can use these straps according to the purpose of use. We use properly. For this reason, the user must prepare various types of straps, which is inconvenient.

An object of the present invention is to provide a strap for a portable telephone device that can be used for various purposes.

[0005]

[Means for Solving the Problems]

 The strap for a mobile phone device according to one embodiment of the present invention includes a winding portion capable of winding only a required amount of a strap, and the length of the strap is adjusted by adjusting the amount of winding by the winding portion. It is characterized in that it can be changed.

The winding section can adjust the winding amount of the strap string so that the length of the strap string can be freely expanded and contracted. The user can, for example, drop the mobile phone device from the neck. When used, for example, the strap is stretched by the winding unit, and conversely, for example, when the mobile phone device is held in hand, the strap is contracted by the winding unit for use.

With this configuration, it is possible to provide a strap for a portable telephone device that can be used for various purposes.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1A and 1B are views showing a mobile phone with a strap attached thereto according to the present embodiment. FIG. 1A shows a state in which a strap is stretched for hanging around a neck, and FIG. The state in which the strap string is contracted is shown.

In FIG. 1, a mobile phone strap includes a winding unit 1, a strap 2 adjusted to a desired length by a user via the winding unit 1, and one end of the winding unit 1. And a support member 3 having the other end fixed to the mobile phone main body 4.

Note that the mechanism of the support member 3 may be a mechanism other than that shown in FIG. 1 as long as the winding unit can be attached to the mobile phone main body. For example, as shown in FIG. Fixing devices 5a and 5b are attached to the winding unit 1 and the mobile phone body 4, respectively, and both ends of the belt 7 are passed through the loops 6a and 6b attached to the fixing devices 5a and 5b, as shown in FIG. 2 (b). It may be a mechanism that can be attached in a fixed manner.

FIG. 3 is a diagram showing the internal structure of the winding section. In FIG. 3, a tape-shaped strap 2 is wound around a rotating body such as a drum 13 in a housing 11. The drum 13 has a circular shape that is rotationally symmetric when viewed from above in FIG. 3, and is rotatable around a central axis (not shown). A biasing spring 15 for rotating the strap string 2 in a winding direction is mounted in the drum 13.

By using the tape-shaped strap string 2 as described above, it becomes easy to wind the strap string around the drum 13. The biasing spring 15 is, for example, a spiral spring (spring). For example, one end is fixed at a predetermined position on the central axis, and is wound around the central axis.

The material of the strap 2 is not particularly limited, but is desirably a material that can be reduced in thickness and is not easily cut. The strap string 2 has its tip a fixed inside the housing 11. The housing 11 has an outlet 18, and the user pulls out the strap 2 wound around the outlet 18 in the direction of arrow A out of the housing 11.

After the strap 2 is pulled out by a desired length, the length of the strap 2 is fixed to the desired length by using the holding member 19. That is, when the button 19a of the holding member 19 is raised upward, one end 19c of the holding member 19 is engaged with the step portion 21, and the bow-shaped holding member 19 is also guided to the bow-shaped guide plate 20. The length of the strap 2 is fixed at the pulled-out position by locking the one surface of the sheet-like strap 2 to the inner wall of the housing 11 by the locking projection 19b located at the tip.

When the button 19a of the holding member 19 is lowered, the engagement between the one end 19c and the step portion 21 is released, and the locking of the strap 2 by the locking projection 19b is released. By the action of the biasing spring 15, the strap string 2 is wound up in the direction of arrow B.

As described above, if the user operates the holding member, the locking projection can lock / unlock one surface of the strap cord 2. That is, if the user pulls out the strap cord 2 to a predetermined pull-out position and operates the holding member 19 at the pull-out position, the winding of the strap cord 2 is prohibited and the strap cord 2 can be held at the pull-out position. it can. It goes without saying that the user can pull out the strap 2 to any position as the pull-out position.

The sealing member 23 prevents the entire strap 2 from being completely entangled inside the housing 11. Further, as the mechanism of the winding unit 2, other than the mechanism shown in FIG.

Similarly, even if the mechanism of the holding member 19 is other than the mechanism shown in FIG. 3, the winding of the strap string 2 by the rotating body such as the drum 13 is prohibited and the strap string 2 can be arbitrarily set. It is possible to employ various mechanisms capable of holding the length. The user adjusts the length of the strap string via the winding section according to the application. For example, when the mobile phone device is to be dropped from the neck, the strap is pulled out for a relatively long time and fixed (FIG. 1 (a)). It is fixed in a state where it is pulled out relatively short (FIG. 1B).

[0019]

[Effect of the invention]

 As described above, according to the present invention, the length of the strap can be adjusted by the winding portion. Thus, the user can use the strap for the mobile phone device of the present invention for various purposes by adjusting the length of the desired strap string according to the purpose of use.
