Abstract

PROBLEM TO BE SOLVED: To provide a holding device whose holding force is not reduced through attachment/detachment of a work to be held in the holding device to hold the work like a hot stick holder to hold a hot stick. SOLUTION: A hot stick H can be received and held between elastic arms 12 by pressing the hot stick H from the upper side, and the hot stick H can be removed by drawing it upward from a hanger 10. Because a guide 20 is arranged before and behind the hanger 10, the hot stick H is moved only in the allowable range of the elastic deformation of the elastic arms 12. Thus, the elastic arms 12 is not plastically deformed in attaching/detaching the hot stick H, and the holding force of the hanger 10 can be kept.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding device for holding an object to be held.

[0002]

2. Description of the Related Art In electrical installation work, a hot wire made of an insulating material is formed in a long shape so that an operator can carry out work without directly touching a live wire. A working tool called a stick is used. Tools such as this hot stick are stored in a tool box provided in the work vehicle and transported to the work site.

A hot stick holder 3 as shown in FIG. 6 is arranged in the tool box, and the hot stick H is held so as not to move in the tool box. The hot stick holder 3 includes a pair of left and right elastic arms 30, 30.
And is formed in a substantially U-shape having an elastic arm 30
Is a bottom plate 31, a rising portion 32 extending upward from both ends of the bottom plate 31, and an arcuate holding portion 33 extending further upward from the rising portion 32 and having an inner circumference 33a abutting the outer circumference of the hot stick H. The holding portion 33 has a tip portion 34 that opens outward from the upper end portion.

In the hot stick holder 3 constructed as described above, the elastic sticks 3 are pushed by pushing the hot stick H from between the tip portions 34, 34.
The hot sticks H are held by elastically deforming 0 and 30 and sandwiching them while being positioned between the holding portions 33 and 33. Then, when removing the hot stick H, the hot stick H is pulled straight up and both tip portions 3
Pass between 4 and 34.

[0005]

Here, if the hot stick H is pushed too hard, the portion 32a connected to the holding portion 33 from the rising portion 32 is spread out as shown in FIG. As shown by the arrow, it may be plastically deformed (permanently deformed) in a state where it is opened to the outside. As a result, there is a problem that the holding force (holding force) required to hold the hot stick H cannot be sufficiently obtained in the holding unit 33.

Further, when the hot stick H held by the hot stick holder 3 is removed and not pulled straight up but pulled up obliquely upward as shown in FIG. 8, only one elastic arm 30 is pulled up. A large force is applied to cause plastic deformation in a state where the hot stick H is open outward, and in this case also, there is a problem that the holding force of the hot stick H in the holding portion 33 decreases.

The present invention has been made in view of the above problems, and in a holding device for holding an object to be held, such as a hot stick holder for holding a hot stick, the holding force is obtained by attaching and detaching the object to be held. An object of the present invention is to provide a holding device that does not deteriorate.

[0008]

In order to achieve the above object, the holding device of the present invention comprises a holding member and a guide member, and the holding member has a pair of left and right elastic arms extending upward. Is formed into a substantially U shape, and the holding object such as the hot stick is received and held between the elastic arms. The guide member is provided at least one of the front and the rear of the holding member, and regulates the downward and leftward and rightward movements of the holding target received and held by the holding member by a predetermined amount or more.

According to the holding device configured as described above,
The holding object can be received and held between the elastic arms by pushing the holding object through the opening formed in the upper portion of the holding member formed in a substantially U shape, and the holding member can be pulled out upward. The object to be held can be removed from. Further, since the holding object does not move downward and leftward or rightward by the guide member or more by the guide member, the holding object is not pushed too much, or is pushed in or pulled out obliquely.

The predetermined movement amount of the holding object regulated by the guide member is preferably a movement amount within the elastic deformation allowable range of the elastic arm. With such a structure, the elastic arm is plastically deformed. I won't let you.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a front surface, an upper surface and a side surface of a hot stick holder 1 which is an example of a holding device according to the present invention. The hot stick holder 1 is composed of a hanger (holding member) 10 and a guide (guide member) 20.

First, the hanger 10 will be described. The hanger 10 is formed by bending a strip-shaped elastic plate material, and extends in the left-right direction, and a pair of left and right elastic plates formed in a substantially U-shape extending upward from the left and right ends of the bottom plate 11. It has arms 12 and 12. The elastic arm 12 includes a rising portion 12a and this rising portion 1
The first holding portion 12b is bent from the upper end portion of 2a and extends obliquely upward and outward, and the second holding portion 12c is bent from the upper end portion of the first holding portion 12b and extends obliquely upward and inward.
And a tip portion 12d that is gently bent from the upper end portion of the second holding portion 12c and opens outward. The portion of the hanger 10 above the intermediate portion of the rising portion 12a is
A vinyl chloride resin coating 13 is applied to the outer periphery thereof.

According to the hanger 10 thus formed, the upper portions of the elastic arms 12 and 12 (that is, both tip portions 1).
By pushing 2d) to the left and right, each elastic arm 12 bends outward and elastically deforms, and if the pushing open force is released, the elastic arm 12 returns to its original shape. That is, when the hot stick H is pushed from above the hanger 10, the hot stick H contacts the tip 13d of the coating located inside the tip 12d, whereby the elastic arm 12 is spread left and right. The hot stick H after passing through the tip portion 13d is
The coating contact portion 13b located inside the bent portion 12e from the 2a to the first holding portion 12b, and the coating contact portion 13c located inside the second holding portion 12c.
It is held at the position where it touches.

Here, in the elastic arm 12, by pressing the hot stick H, both contact portions 13b, 13b,
13c is in contact with the first and second holding portions 12
b and 12c are formed so as to have an urging force to be urged inward (that is, the hot stick H is sandwiched between the contact portions 13b and 13c).

Next, the guide 20 will be described. The guide 20 is composed of a bottom plate 21, a front plate 22 extending upward from the front of the bottom plate 21, and a rear plate 23 extending upward and fixed to a rear end portion of the bottom plate 21, as shown in FIG. The side surface is formed in a U shape. The front plate 22 and the rear plate 23 have a U-shaped notch 22a having an opening at the top.
23a are formed.

The bottom plate 21 and the front plate 22 thus formed
The coating 24 is also applied to the outer periphery of the rear plate 23, and the inner method W2 of the front plate 22 and the rear plate 23 with the coating 24 is the width W1 of the hanger 10 with the coating 16. A little wider than
Notches 22a, 2 with coating 24 applied
The width WH of 3a is formed to be slightly larger than the outer diameter D of the hot stick H. Also, the notches 22a and 23
The a is formed to extend below the contact portion 13b.

As a result, when the hot stick H is sandwiched between the contact portions 13b and 13c, gaps S1 and S1 are formed on the left and right sides of the hot stick H, and the lower end of the hot stick H and the notches 22a and 23a are formed. A gap S2 is also formed between the lower ends 22b and 23b.

On the bottom plate 21 of the guide 20 formed in this way, the bottom plate 11 of the hanger 10 is placed, and the mounting hole 11a formed in the bottom plate 11 and the mounting hole 21a formed in the bottom plate 21 are formed. The hanger 10 and the guide 2 are fastened together with the board K by bolts (not shown).
0 is fixed, and the guide 20 is attached to the substrate (bottom plate or side plate of the tool box) K.

As shown in FIGS. 4 and 5, the hot stick holder 1 is attached on the substrate K by opening upward and sideways, and the hot stick H is pushed in from the opening direction to the hot stick holder 1. The hot stick H can be held and if the hot stick H is pulled out, the hot stick holder 1
The hot stick H can be easily removed from the.

The portions of the hanger 10 and the guide 20 of the hot stick holder 1 that come into contact with the hot stick H are coated with vinyl chloride resin coating 16 and 24, so that the hot stick H may be damaged. Without, it can be smoothly attached and detached.

Further, the hot stick H has both contact portions 1
In the state of being sandwiched by 3b and 13c, it can be moved downward and leftward and rightward until its outer periphery comes into contact with the inside of the notches 22a and 23a, that is, by the gaps S1 and S2. It should be noted that the amount of such movement is the predetermined movement amount described in the claims. Here, when the hot stick H moves, the elastic arms 12 and 12 are deformed, but in the hot stick holder 1, this deformation amount is formed to be a deformation amount (movement amount) within an elastic deformation allowable range. . Therefore, the hot stick H
Even if is moved, the elastic arms 12 and 12 do not plastically deform.

In the hot stick holder 1 described above, the gaps S1 and S2 are provided in order to set the predetermined movement amount within the elastic deformation allowable range of the elastic arm 12, but the hot sticks are made by narrowing the gaps. It may be configured such that H hardly moves (the predetermined moving amount is close to zero). With such a configuration, the lower portion of the hot stick H can be held by the lower end portions 22b and 23b of the cutouts 22a and 23a instead of being held by the contact portion 13b.
It is not necessary to form the first holding portion 12b in the above, and the structure of the elastic arm can be simplified.

[0023]

As described above, in the holding device of the present invention, the holding object can be received and held between the elastic arms by pushing the holding object from above, and the holding member can be pulled out upward. The object to be held can be removed from. Since the guide members are arranged before and after the holding member, the holding target moves only within the elastic deformation allowable range of the elastic arm. Therefore, it is possible to maintain the holding force of the holding member without plastically deforming the elastic arm when attaching or detaching the holding object.
