Description

  The present invention relates to a wire device for preventing a tool attached to a waist belt or the like from falling.

In this type of prior art, a tool that is detachably inserted into a tool sack of a safety belt is configured to be hooked and connected to the safety belt using a short elastic cord (for example, (See Patent Document 1).
Japanese Utility Model Publication No. 63-113581

The above-mentioned prior art uses an elastic spiral cord, so it will not get in the way because it expands when using a tool and contracts when not in use, but if multiple spiral cords are attached, they will be entangled with each other Sometimes.
An object of the present invention is to provide a tool fall prevention wire device that can solve such problems of the prior art.
The present invention provides a wire device for preventing the dropping of a tool, in which a cover body is fitted to a coiled portion of a wire so that the coiled portion of the wire can be prevented from being entangled even when a plurality of wires are attached simultaneously. For the purpose.

Specific means for solving the problems in the present invention are as follows.
First, a wire W in which a coiled portion W3 is formed between the mounting side end W1 and the tool connecting side end W2 and a cover body K fitted to the coiled portion W3 of the wire W. Have
The cover body K includes a bellows cylindrical portion K1 fitted to the coiled portion W3, an attachment portion K2 attached to the attachment side end W1 of the wire W at one end of the bellows cylindrical portion K1, and the bellows cylindrical portion K1. And the opening K3 from which the coiled portion W3 of the wire W can be pulled out is formed at the other end of
A fastener T for fastening the attachment portion K2 of the cover body K is provided at the mounting side end W1.

Second, the cover body K is made of a transparent resin, the bellows cylindrical portion K1 has large diameter portions K1a and small diameter portions K1b alternately in the longitudinal direction of the wire, and the attachment portion K2 is a bellows cylindrical portion. It is characterized by being tapered from K1 to the wire W.
Thirdly, a pair of the fasteners T is provided at the wire W attachment side end portion W1 with an interval in the wire longitudinal direction, and the attachment portion K2 of the cover body K is tapered between the pair of fasteners T. It is characterized in that a ball-shaped tip K2a is fastened.

  According to the present invention, even when a plurality of wires are attached simultaneously, the cover body can prevent the coiled portions from being entangled.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1-4, the wire device 1 for fall prevention has the elongate wire W and the cover body K made from transparent resin.
The wire W includes an attachment-side end W1 attached to an operator's waist belt or the like via a hook 3, a tool connection-side end W2 connected to a tool such as an electric drill via a hook 4, and the like. It has a coiled portion W3 formed between the mounting side end W1 and the tool connection side end W2.
The mounting end W1 is formed in a loop shape at the outermost end and connected to the hook 3, and the end portion W2 on the tool connection side is also formed in a loop and connected to the hook 4. The tool connecting side end portion W2 is formed to have a longer dimension in the wire longitudinal direction than the mounting side end portion W1, and the coiled portion W3 is located closer to the waist belt and the hook 3.

The cover body K has a substantially bottomed cylindrical shape. The bellows cylindrical portion K1 fitted to the coiled portion W3 and one end portion (bottom side) of the bellows cylindrical portion K1 are attached to the attachment side end portion W1 of the wire W. An attachment portion K2 to be attached and an opening K3 from which the coiled portion W3 of the wire W can be pulled out are formed at the other end of the bellows cylindrical portion K1.
As is apparent from FIGS. 1 and 2, the bellows cylindrical portion K1 has arcuate mountain-shaped large-diameter portions K1a and arc-valley-shaped small-diameter portions K1b alternately in the longitudinal direction of the wire, and the outer peripheral surface has a wave shape. ing.
The attachment portion K2 has a tapered shape (substantially conical shape) from the end edge of the bellows cylindrical portion K1 to the wire W, and the narrowed tip K2a is fastened to the wire W.

The opening K3 allows a part of the coiled portion W3 of the wire W to freely enter and exit. Since the mounting portion K2 is immovable with respect to the mounting side end W1 side of the coiled portion W3, when the tool connecting side end W2 is pulled to use the tool, the coil shape is connected to the tool connecting side end W2. The opening K3 is provided so that the portion W3 is pulled and the coiled portion W3 is exposed from the bellows cylindrical portion K1 while elastically extending.
A pair of fasteners T is provided at the mounting-side end W1 of the wire W at intervals in the wire longitudinal direction. The pair of fasteners T fit and fasten the tapered tip K2a of the attachment portion K2 therebetween. By this fastener T, the cover body K is immovable with respect to the mounting side end W1 side of the coiled portion W3 of the wire W, and the cover body K always covers the coiled portion W3.

In FIG. 4, the drop preventing wire device 1 has an attachment side end W <b> 1 of a wire W attached to an operator via a hook 3, and a tool connection side end W <b> 2 via a hook 4. Even if the electric drill 5 is accidentally dropped, the wire W is stretched to prevent further dropping.
When the electric drill 5 is used, if the electric drill 5 is moved away from the body, the tool connecting side end W2 is pulled, so that the coiled portion W3 extends elastically and protrudes from the opening K3. When the electric drill 5 is brought close to the body and when the tool connection side end W2 is released from the tension, the coiled portion W3 contracts due to the restoring action due to its shape and enters the bellows cylindrical portion K1 through the opening K3. .

  Therefore, even if the operator wears a plurality of tools with the wires W, the coiled portions W3 of the wires W are covered with the cover body K, so that the entanglement is prevented.

It is a front view of the principal part which shows embodiment of this invention. It is a whole front view of the wire device for fall prevention. It is explanatory drawing of the use condition of the wire apparatus for fall prevention. FIG. 3 is a view taken in the direction of arrow X in FIG. 2.
