Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in the attachment structure of a fall prevention wire for a portable device, such as a small radio device, which is stored and carried in a pocket of clothing.

(Prior art) Portable small devices such as small order receivers and selective calling devices (hereinafter referred to as
(referred to as "portable devices") are devices that are carried in clothes, bags, etc., and are taken out and used when necessary.9 When these portable devices are carried in a pocket. The fifth
Falling is prevented using a fall-preventing chain 1 as shown in the figure.

The fall prevention chain 1 is fixed to the device 2 at one end, and has a clip 3 at the other end to be clipped to the edge of a pocket, the belt loop of pants, or the like.

The conventional chain 1 is set at a length suitable for use by taking it out of a clothing pocket and holding it in the hand. Problems may occur, such as tangles with writing utensils, etc., or chains hanging from pockets. Also, the optimal length of the chain will be closer to your stomach depending on when you take out and use a mobile device stored in your chest pocket or when you take out and use a mobile device stored in the inside pocket of a suit, so the length of the chain in which it is stored will be different from the pocket in which it is stored. There is a strong tendency to lengthen the chain so that it can be used regardless of its position, and this tendency promotes the occurrence of problems such as -F. Also, when carrying a mobile device with a breakable chain attached to the hip belt, the chain is not needed, so the chain is wrapped around the mobile device and stored in the case. Improvements have been desired since not only the operability during storage but also the operability when taking out is deteriorated.

(Object of the Invention) The present invention has been made in view of the above, and it is an object of the present invention to arbitrarily and easily adjust a chain, etc. for preventing a small portable device from falling to an optimal length depending on the storage location. It is an object of the present invention to provide a structure for attaching a fall prevention wire for a portable device, etc., which can be used to prevent the fall of a portable device, etc., and which can be housed inside the device when a chain or the like is not required.

(Summary of the Invention) In order to achieve the F2 objective, the present invention supports a wire rod for preventing falling pages through a through hole provided in the housing of a small portable device so as to be able to move in and out of the housing. A locking means is provided, the inner end of which is urged into the housing by a pulling means, and which locks the wire at a desired length when the wire is pulled out to the outside against the urging force of the drawing means. It is characterized by being provided at the periphery of the through hole.

Moreover, the present invention arranges a plurality of fasteners on the outer wall surface of the casing of a small portable device, and a hook that is latched to the fasteners is fixed to one end of the fall prevention wire. It is characterized by

A vertically elongated space 12 is formed inside one side wall 11 of 10,
The E end of a spring (retracting means) I4 whose lower end is supported by a fixing screw 13 provided on the bottom surface of the space I2 is fixed to the inner end 15a of a wire 15 such as a chain. Chain I5 is side wall 1
It is inserted into a through hole 16 provided in the upper part of the holder 1 and is supported so as to be movable in and out. The locking spring 9 locks the drawer at a desired length.

The locking cylinder 18 and the locking spring 19 constitute a locking means.

The locking tube 8 is a hollow cylindrical body, and a notch 20 extending in the radial direction is formed in the side surface thereof. The locking spring I9 is made of a metal wire material or a narrow plate material having spring properties, and has a linearly extending expansion piece 19a, and aligns the - end of the expansion piece 19a with the outer peripheral surface of the locking cylinder 18. Bullet piece curved into a shape +

The locking spring 19 is configured by fitting the expansion piece +9a of the locking spring 19 into the notch 2o of the locking cylinder 18, and also by fitting the expansion piece +9a of the locking spring 19 into the notch 2o of the locking cylinder 18.
It is attached to the locking tube 18 by making the landing piece +9b hit on the upper part of the outer peripheral surface of the locking tube 18.

The depth of the notch 20 is such that the space S formed between the expansion piece 19a and the inner wall of the locking tube 18 when it is completely inserted into the notch clamps and locks the wire rod 15 of the chain. When the 7-expansion piece 19a, which is set to be so narrow as to be immovable, is pressed with a finger in the expansion direction (downward in this embodiment),
The space S is enlarged and the wire rod 15 inserted therethrough can be moved. When the pressing force in the expansion direction is released, the expansion piece 1
9a returns to its original shape by its own spring force and clamps the wire 15 therebetween.

A cleat/I-bu 22 is fixed to the tip of the wire 15 to be clamped to the edge of a pocket of clothing or the like.

In the above embodiment, a chain is used as the wire rod 15, but instead of the chain, a curl cord made of resin or the like may be used. If a curl cord is used, the wire rod 15 can be expanded depending on the thickness of the wire rod. The space S between the piece 19a and the inner wall of the locking tube 18 is set to an optimal size.

In addition, although the example in which the expansion piece 19a is configured in a straight line is shown,
In order to increase the clamping force, it is effective to curve the contact portion with the wire toward the inner wall of the locking tube 18, provide a protrusion, or process it into a rough surface.

Further, a recess or the like for fixing the bullet landing piece +9b may be provided in the outer peripheral surface portion of the locking tube 18 with which the first bullet landing piece +9b comes into contact. The cross-sectional shape of the impact piece +9b is not limited to a circular shape, and the cross-sectional shape of the locking tube 1
The expansion piece +9a may have an arc shape, a semicircle shape, a plate shape, etc., which can easily adhere to the outer peripheral surface of the expansion piece +9a, and the cross-sectional shape of the expansion piece +9a can also be changed to a shape suitable for enhancing its function.
