Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fall prevention device for small portable equipment.

Conventionally, as shown in FIG. 1, this type of drop-off prevention device has a clasp 12 fixed to the side surface of a casing 11, and a chain 14 with an auxiliary clip 13 connected to one end thereof is connected to the clasp 12 at the other end.
It is connected to a hole 12a provided in the hole 12a. Reference numeral 16 is a main clip that clamps clothing and secures the device when carried.
%/M''k When carrying a device equipped with such a device to prevent it from falling off, if you try to store it in your clothes pocket, the catch 12 protruding from the side of the casing 11 may get caught, and the device cannot be stored smoothly. There is a drawback that it cannot be done.

The present invention eliminates the above-mentioned drawbacks and provides a fall prevention device for portable devices that can be smoothly stored in clothing pockets or the like.

The invention is explained below along with examples thereof. Note that each arm 6 is provided with a through hole 6a.

Reference numeral 2 denotes a main grip, and a clip seat 9 having a through hole 9a having the same diameter as the through hole 6a is provided on the upper part of the main grip. 3 is a cylindrical operating shaft having a diameter somewhat smaller than that of the through holes 6a and 9a; 3a is a head ring that is provided at one end of the operating shaft 3 and also serves as a stopper; a small hole 3b is provided in a part of the head ring; There is. 3C is an annular groove provided at the other end of the operating shaft 3;
numeral 3 is a chain attached to the small hole 3b of the head ring 3a, 6 is an auxiliary clip attached to the other end of the chain, 7 is a plate-shaped elastic body bent into a V shape, and one side of the V shape is the Body part 1
This is a spring fixed with the figure 7 opening facing upward. 8 is an E ring that fits into the groove 3C.

In the above configuration, if the clip seat 9 of the main clip 2 is inserted between the arms, the operating shaft 3 is passed through the hole 6a and the through hole 9a, and the E ring 8 is fitted into the groove 3C at the tip, the main clip 2 is attached to the radio device housing 1.

When using a device equipped with this drop-off prevention device, the main clip 2 should be used to hold the upper end of the chest pocket, and the auxiliary clip 6 should be used to clip other parts of the chest pocket or the chest button, etc. The housing 1 is held by both the main clip and the auxiliary clip, and there is no fear of it falling even if the main clip comes off.

In addition, since the drop-off prevention device uses a forward ring 3a that is integrated with the operating shaft 3 of the main clip 2, there is no need for a retaining metal fitting to protrude from the side of the housing as in the conventional case, and the device can be placed in a clothing pocket. It can be stored smoothly. Further, since one end of the chain 4 is fitted into the forward ring 3a, the twisting of the chain is resolved by the natural unraveling of the forward ring 3a and the action@3.

In the above embodiment, the order ring 3a and the auxiliary clip 6 are connected to the chain 4.
However, other connecting members such as leather straps, plastic straps, etc. can also be used.

As is clear from the above embodiments, in the fall prevention device for a portable device according to the present invention, one end of the connecting member for preventing fall is connected to the shaft of a clip that is fastened to a pocket by providing a hole in the case. There is no need to separately provide a fastener on a part of the body, so there is an advantage that there is no obstructive protrusion, the manufacturing cost is low, and the industrial value is high.
