DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. Although the illustrated embodiment is an example in which the invention is applied to a radio telephone used in a flammable gas or an external atmosphere, the invention can be applied to other portable electric devices such as a mobile telephone.

The wireless telephone A has a hard resin case containing a circuit board on which various electric elements are mounted.
The hard resin case made of an electrically insulating material such as resin is composed of an upper case 1 and a lower case 2 which are injection-molded into an elongated container shape with one surface opened. Also,
An antenna 3 protrudes from the upper part of the hard resin case, and a power button 4 for turning on the power and a dial key 5 for calling a partner telephone are arranged on the surface of the antenna 3.

In the present invention, the radiotelephone A externally covered with the hard resin case is provided with the upper case 1 and the lower case 2 so that the resin case is not ignited by sparks generated inside due to deformation of the resin case at the time of a drop impact or "crack". It is wrapped in a soft case B that covers the whole. The soft case B includes a skin trim 11 that covers the front, top, and back surfaces of the hard resin case of the wireless telephone A, and a side trim 12 that covers the left, right, side, and bottom surfaces of the hard resin case. An edge corresponding to the side trim 12 is sewn with a rim 13.

That is, on the surface of the skin trim 11, a lamp window 15, a speaker hole 16 for exposing the reception state display element of the radio telephone A to the outside, and an area for exposing the display and dial key 5 of the radio telephone A to the outside. Large display window 17
The display window 17 is covered with a relatively flexible transparent resin sheet 18 such as a vinyl chloride sheet.

A terminal hole 21 corresponding to an external connection terminal (not shown) of the radiotelephone A is formed on one end surface of the side trim 12, and a length of the terminal trim 21 is set at an intermediate portion of the side trim 12. A slit 22 extending in the direction is formed,
It is closed by the slide fastener 23 sewn to this slit position. Therefore, by opening and closing the slide fastener 23, the wireless telephone set A can be taken in and out when the battery is worn out or at the time of failure. Note that reference numerals “24, 25” in FIG.
Is a shock absorbing pad for alleviating a shock at the time of a drop impact.

On the back surface of the skin trim 11 of the soft case B, a hanger hook 3 injection-molded with ABS resin or the like.
The soft case B housing the wireless telephone A is detachably supported on the waist belt WB of the wearer by using an elastic tongue piece 32 integrally formed with the hanger hook 31. That is, in the present invention, for the attachment to the waist belt WB, a rectangular thin plate-like support member 41 made of a material having a small surface friction coefficient (for example, a polyethylene low foam material) is prepared.
1 is a pair of retainer bands 42, 43 fixed on both sides.
And attached to the wearer's waist belt WB as necessary.

In the case of the illustrated embodiment, as shown in FIG. 2, "U" -shaped retainer bands 42 made of synthetic leather are provided on both sides of the plate-shaped support member 41 on the waist belt WB side.
43 is sewn to one side of the retainer band 42,
43 is a waist belt WB as shown in FIG.
After passing through the waist belt WB, it is closed in a loop by the hook fastener 45 so as not to come off from the waist belt WB.
Retainer bands 42, 43 closed with hook fasteners 45
Has a sufficient length so as to be able to cope with an arbitrary waist belt WB having a different width, so that the plate-like support member 41 is tilted by a certain angle by the two retainer bands 42 and 43 in a loose state. Waist belt WB
Will be supported. Also, the retainer band 42,
43 is a waist belt WB on both sides of the plate-shaped support member 41
Since it is sewn on the side surface, the retainer bands 42, 4
In the state where the plate-shaped support member 41 is attached to the waist belt WB in 3, as shown in FIG.
Between the waist belt WB and the retainer band 42,
A space corresponding to the thickness of 43 is formed.

On the other hand, as shown in FIGS. 3 and 4, on the inner surface of the tip of the tongue piece 32 integrally formed with the hanger hook 31, a retaining claw 33 is formed so as to project at a right angle, and the lower surface of the retaining claw 33 has an inclined surface 33a. It is said. Therefore, when holding the wireless telephone A on the waist belt WB of the wearer, as shown in FIG. 1, the inclined surface 33a of the retaining claw 33 is applied from above the plate-like support member 41 attached to the waist belt WB in advance. When the wireless telephone A is strongly pressed downward, the tongue 32 is elastically deformed by the vector component applied to the inclined surface 33a, and as shown in FIG.
Of the plate-like support member 41 from the tongue piece 32 is prevented by the retaining claw 33.

Further, one side surface of the above-mentioned retaining claw 33 is formed on the inclined engaging surface 3 which can be engaged with a corresponding side edge of the plate-like supporting member 41.
3b, the hanger hook 31 engaged with the plate-shaped support member 41 can be forcibly removed using the inclined engagement surface 33b. That is, the alternate long and short dash line α in FIG. 6 indicates the plate-like support member 41 for the hanger hook 31 when the wireless telephone A is attached to the waist belt WB.
In order to remove the wireless telephone A from the waist belt WB, the wireless telephone A held by hand may be rotated clockwise around the hanger hook 31 in FIG. With this operation, the plate-shaped support member 41 is relatively rotated with respect to the radiotelephone A to the position indicated by the alternate long and short dash line β, and the lower edge of the plate-shaped support member 41 is engaged with the inclined engagement surface 33b. The movement stops. Therefore, when the turning operation of the wireless telephone A is continued, both the retainer bands 42 and 43 supported at both ends, which are loosely fitted to the waist belt WB, are tilted and turned with respect to the waist belt WB. The upper and lower ends of the U-shaped retainer bands 42, 43 at both ends become fixed ends with respect to the waist belt WB, and the tilting of the retainer bands 42, 43 stops. In accordance with this movement, the plate-like support member 41 increases its inclination while maintaining the relative position with respect to the hanger hook 31.

Therefore, when the wireless telephone A is further strongly rotated by hand, the tongue piece 32 is elastically deformed by the vector component force of the rotating operation, the plate-like support member 41 is detached from the retaining claw 33, and the wireless telephone A Comes off the waist belt WB. In the case of the illustrated embodiment, when the plate-shaped support member 41 is detached from the retaining claw 33, the plate-shaped support member 41 can be sufficiently inclined with respect to the body by loosely attaching the retainer bands 42 and 43 to the waist belt WB. Therefore, the detaching operation of the wireless telephone A can be performed lightly.

Since the belt hanger of the portable device according to the illustrated embodiment has the above-described structure, the mobile phone A can be held on the waist belt WB of an operator or the like as necessary to carry the band. In other words, to carry the wireless telephone A,
The plate-like support member 41 is attached to the waist belt WB in advance by the retainer bands 42 and 43, and the hanger hook 31 of the soft case is attached to the plate-like support member 41. In this case, the body of the waist belt WB such as an operator After passing the retainer bands 42 and 43 to the sides, it is only necessary to attach the plate-shaped support member 41 to the waist belt WB with the hook fastener 45, so that the waist belt WB can be removed from the clothes regardless of the width and thickness of the waist belt WB. The mobile can be prepared without removing it. Further, even when the wireless telephone A becomes unnecessary, there is a convenience that the hook fastener 45 is removed and the retainer bands 42 and 43 are simply removed from the waist belt WB.

The radio telephone A in the band is connected to the plate-like support member 4.
Since the worker 1 is held by the waist belt WB of the worker or the like, both hands of the worker become free. Then, in order to use the portable radio telephone A, the radio telephone A can be easily removed from the plate-like support member 41 simply by rotating the radio telephone A together with the soft case in one direction. Since the retaining claw 33 can be kept in the holding state only by applying the retaining claw 33 to the upper edge of the support member 41 and pushing it downward, the attachment / detachment operation is light.

[0019]

As is apparent from the above description, according to the present invention, a thin plate-like support member is attached to a waist belt in advance, and a tongue formed on a hanger hook of a portable device is hooked and held. A light attachment / detachment operation can be performed without being affected by the thickness and hardness of the device.

Further, according to the structure in which the plate-shaped support member is attached to the waist belt by the retainer band with the hook fastener, the waist belt of the wearer can be provided together with the band of the portable device without removing the waist belt.
