Abstract

PROBLEM TO BE SOLVED: To simplify the support and movement of a mounting hook by forming tow notch parts notches from respective reverse directions, at the gripped sides of both grip members. SOLUTION: Both grip sides 1c and 2c of a mounting hook 7 are held up, opening wide a gap between two tip parts 1b and 2b, and this mounting hook 7 is clamped to a main rope 8 or the like. Since two nonslip members 5a and 5b are stuck to these tip parts 1b and 2b, the main rope 8 is firmly holdable. Supposing that top and bottom of these tip parts 1b and 2b are reversed, since two longitudinal notch parts 6a and 6b are formed at the grip sides 1c and 2c from the reverse direction each, a hook part is made up in these grip sides 1c and 2c, whereby a proper part of a maintenance apparatus 9 of a lighting fixture connected to a power source through a power cord 10 is holdable on this hook part. In the case where this maintenance apparatus 9 is moved with the progress of operations, the grip sides 1c and 2c are held up, opening wide a gap between the tip parts 1b and 2b, and thus it is shiftable to a proper position along the main rope 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance tool attachment hook for holding a maintenance tool used in an elevator hoistway or the like.

[0002]

2. Description of the Related Art Generally, when performing work in a hoistway of an elevator, maintenance equipment such as a lighting equipment for illuminating a hand is required, and these conventional maintenance equipment are provided with an appropriate member located near the power cord. Was wrapped around and supported.

[0003]

However, maintenance equipment such as lighting equipment needs to change the irradiation direction or move the location as the work progresses, but the conventional maintenance equipment has its power cord. Since it was wrapped around an appropriate member, the power cord had to be unwound each time and re-attached at another position, which was a troublesome work.

It is an object of the present invention to provide a hook for attaching a maintenance tool which is easy to support and move.

[0005]

In order to achieve the above object, the present invention provides a maintenance tool comprising a pair of clip members connected via a spring and applying a force in a direction in which they are in close contact with each other. In the attachment hook, notches formed by cutting in opposite directions are formed on the grip sides of the clip members.

[0006]

The hook for mounting the maintenance tool according to the present invention has the notches cut from opposite directions on the grip sides of both clip members as described above. The parts can be used, the maintenance tool can be easily supported and moved, and the handleability can be improved.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a side view and a plan view showing a hook 7 for mounting a maintenance tool according to an embodiment of the present invention. The pair of symmetrical clip members 1 and 2 have connecting portions 1a and 2a whose intermediate portions are connected by a connecting pin 3, and the ends of the spring 4 wound around the connecting pin 3 are respectively clip members 1 and 2. Is applied to the opposite side of. Therefore, a force is applied to the clip members 1 and 2 by the spring 4 in a direction to bring the tip portions 1b and 2b into close contact with each other, and the clip members 1 and 2 are reinforced so as to sufficiently withstand this force. Non-slip members 5a and 5b made of rubber or the like are attached to the opposite sides of the tip portions 1b and 2b so that they can be firmly held by a symmetrical object sandwiched. Cutout portions 6a and 6b are formed on the gripping sides 1c and 2c, which are the other ends of the clip members 1 and 2, respectively, and are oriented laterally from the opposite direction.

FIG. 3 is a side view of an essential part of the elevator showing a usage state of the above-mentioned attachment hook of the maintenance tool. When working in the hoistway, it is necessary to hold maintenance equipment such as lighting equipment at a predetermined position. First, the gripping sides 1c and 2c of the above-mentioned maintenance equipment attachment hook 7 are picked up and the tip portion 1 is held.
Open between b and 2b, and fix the hook 7 for attaching the maintenance tool to an appropriate member such as the main rope 8. At this time, the tip 1b,
Since the non-slip members 5a and 5b are attached to the 2b, the main rope 8 can be firmly held. Even if the tips 1b and 2b are turned upside down, the gripping sides 1c and 2c are formed with the notches 6a and 6b which are oriented in the opposite direction, that is, in the state shown in the drawing,
The grip side 1 is formed by one of the notches 6a and 6b.
The c and 2c are provided with a hook portion, and the hook portion holds an appropriate portion of the maintenance equipment 9 of the lighting equipment connected to the power source (not shown) by the power cord 10.

When the maintenance tool 9 is moved as the work progresses, the gripping sides 1c, 2 of the maintenance tool attachment hook 7 are moved.
It can be moved to an appropriate position along the main rope 8 by picking c and opening between the tip portions 1b and 2b. In another example, the hook 7 for attaching another maintenance tool is clamped at an appropriate position on the main rope 8 and the moved maintenance tool 9 is held by the hook 7 for attachment of the new maintenance tool, which is used until then. By removing the maintenance tool attachment hook 7 from the main rope 8, it is possible to prevent the maintenance tool 9 from being accidentally dropped while the maintenance tool attachment hook 7 is moving. Moreover, since the notches 6a and 6b are formed on the grip sides 1c and 2c from the opposite directions, respectively, when the hook 7 for attaching the maintenance tool is held by the main rope 8, the notches 6 are formed.
Since one of the hooked portions of a and 6b can be used without fail, workability is good. However, when notches 6a and 6b are formed on the grip sides 1c and 2c in the same direction, the notches 6a and 6b may both face downwards, which may be time-consuming. is there. Further, the maintenance tool can be more easily supported and moved than when the holes are formed on the grip sides 1c and 2c, and the handleability can be improved.

In the above-mentioned embodiment, the case where the attachment hook 7 of the maintenance tool is held by the main rope 8 has been described, but other members may be held, and the maintenance tool other than the elevator may be attached. It can also be used as the hook 7.

[0011]

As described above, since the attachment hook of the maintenance tool according to the present invention has the clip member having the cutouts in the opposite directions on the grip side, the maintenance tool can be supported and moved. It is simple and can be handled easily.
