Abstract

(57) [PROBLEMS] To improve the attachment structure of a hand strap of a portable device so that the portable device can be easily miniaturized, manufactured at a low cost, and have sufficient strength. A screw (9) for connecting a front case (1) and a rear case (2) is provided, and an annular piece (10) through which a hand strap string (11) is passed is attached to a head (9a) of the screw (9).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for attaching a hand strap to a portable device.

[0002]

2. Description of the Related Art A conventional hand strap is attached to a portable device such as a portable telephone or a pager by passing the hand strap through an insertion hole (guide hole) opened at a corner of a portable device case. . FIG. 2 is a partial view of a portable device illustrating attachment of a conventional hand strap.
(A) is an external view of a main part of the portable device, (b) is a cross-sectional view along AA, and (c) is a cross-sectional view along BB.

A case of a portable device comprises a front case 1 and a rear case 2 and an insertion hole 3 for a hand strap string is opened at an upper corner of the rear case 2.

FIG. 2C shows a structure in which a front case 1 and a rear case 2 are fitted and fixed by claws 5 at the upper part of the portable device.

[0005]

However, in order to form the insertion hole 3 in the case, it is not possible to form the insertion hole 3 only by pushing out the mold, and in addition to this, a slide method must be used and the mold cost is increased. Expensive. Similarly, a mold slide method is used for forming the claws 5 for fitting and fixing the front case 1 and the rear case 2, so that the mold cost becomes expensive. In the case of the coupling structure in which the claws 5 are fitted and fixed, there is a possibility that the front case 1 and the rear case 2 may be opened by an impact when dropped.

In addition, since the insertion hole 3 is provided, the thickness of this portion cannot be reduced, which hinders miniaturization of the portable device. In particular, in recent years, there has been fierce competition for miniaturization of wireless devices such as mobile phones, and it is desired to improve the structure for attaching a hand strap string.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems in the prior art, the present invention comprises a screw for connecting a front case and a rear case, and attaches an annular piece through which a hand strap string is passed to the screw head. I did it.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG.
It will be described based on. 1A is a cross-sectional view of a main part of a portable device, FIG. 1B is a top view of a screw, FIG.
(D) is an external view of a main part of the portable device.

A boss 6 is provided on the front case 1. The rear case 2 has a recess 7 in which the head of the screw is embedded and a hole 8 in the bottom of the recess 7 for passing the screw. The screw 9 is provided with a strap 10 (annular piece) through which a hole is formed in the head 9a and which can be easily cut off with a strap made of wire or the like. As shown, the front case 1 and the rear case 2 are
Is inserted into the inside of the case from the recess 7 and tightened to the boss 6, the screw head 9a is buried in the recess 7, and the surface of the rear case 2 becomes flat. Then, the hand strap string 11 is tied to the strap 10 through the strap.
Can be used to suspend mobile devices. When the head 9a of the screw 9 has a poor external appearance, a blind sheet or a rubber sheet may be attached.

With the above-described configuration, the hand strap string insertion hole 3 (guide hole) provided in the case as in the related art is eliminated, so that the case can be easily made thinner, which is advantageous in reducing the size of a portable device. . In addition, since the hand strap string insertion hole 3 is eliminated and the claw 5 for fitting and fixing the front case 1 and the rear case 2 is not required to be formed in the case, the structure of the case is simplified and the cost for the mold is greatly reduced. You. Further, since the hood case 1 and the rear case 2 are connected by the screw 9, it is possible to sufficiently withstand the impact at the time of drop.

[0011]

According to the present invention, since a screw for connecting the front case and the rear case is provided, and an annular piece is attached to the screw head, the case can be easily made thinner, which is advantageous in miniaturizing portable equipment. . In addition, the structure of the case is simplified, and the cost of the mold is greatly reduced. Furthermore, it is strong against the impact of falling.
