Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a lever grip support structure for a lever-type hoisting and traction device that carries out hoisting, transporting, towing, etc. of loads by repeatedly swinging the lever. .

[Prior art]

Conventionally, as a lever grip support structure for a lever-type hoisting and traction device, a structure in which a cylindrical grip made of an elastic material such as rubber is fitted and fixed to the tip of a metal lever with adhesive is known. .

However, in the case of the above-mentioned conventional lever grip support structure, the troublesome work of applying adhesive is required, and the cylindrical grip becomes worn or damaged after long-term use, making it necessary to replace the cylindrical grip with a new one. If this occurs, cut the old cylindrical grip, peel it off from the metal lever, scrape off the adhesive adhering to the metal lever, and then glue the new cylindrical grip to the metal lever. Since the cylindrical grip must be fitted by applying a compound, there is a problem that the replacement work of the cylindrical grip is complicated and the replacement work takes a long time.

[Purpose of the invention, structure]

The object of this invention is to provide a lever grip support structure for a lever-type hoisting and traction device that can advantageously solve the above-mentioned problems.
The gist of this invention is that a locking hole 3 is provided at the tip of a metal lever 2 in a lever-type hoisting and traction device 1, and a cylindrical shape made of an elastic material is integrally provided with a locking protrusion 4 on the inner surface. A lever type device characterized in that the grip 5 is fitted into the hollow tip of the metal lever 2 of the lever type hoisting and traction device 1, and the locking protrusion 4 is fitted into the locking hole 3. This is in the lever grip support structure of the hoisting and traction device.

〔Example〕

Next, this invention will be explained in detail using illustrated examples.

1 to 4 show a first embodiment of this invention, in which a metal lever 2 of a lever-type hoisting and traction device 1 has an oval cross section (oval shape).
A circular locking hole 3 is provided in the flat plate part of the hollow tip, and the outer peripheral surface has anti-slip unevenness 6, and the cross section is oval and the tip is closed. It is made of an elastic material such as rubber. A circular locking projection 4 made of an elastic material such as rubber is integrally provided on the planar inner surface of the cylindrical grip 5, and the cylindrical grip 5 made of an elastic material equipped with the locking projection 4 is attached to the metal lever. 2, and the locking protrusion 4 is fitted into the locking hole 3.

5 and 6 show a second embodiment of this invention, in which locking holes 3 are provided in the flat plate portions on opposite sides of the hollow tip of the metal lever 2, and the lever is made of an elastic material. Locking protrusions 4 are integrally provided on the planar inner surfaces of both opposing sides of the cylindrical grip 5, and a guide is provided on the grip insertion side at the tip of each locking protrusion 4 to facilitate grip insertion. Although a slope 7 is provided, the other configurations are the same as in the first embodiment.

In the case of the first embodiment as well, the guide slope 7 as described above may be provided at the tip of the locking projection 4. In addition, when implementing this invention, the locking hole 3 and the locking protrusion 4
The shape may be any shape other than circular.

[Effect of idea]

According to this invention, the lever type hoisting and traction device 1
A locking hole 3 is provided at the tip of the metal lever 2 in , and a locking protrusion 4 is integrally provided on the cylindrical grip 5 made of an elastic material, which is fitted into the tip. The locking protrusion 4 of the elastic cylindrical grip 5 can be removed by simply pushing and fitting the elastic cylindrical grip 5 equipped with the locking protrusion 4 onto the tip of the metal lever 2. Automatically fit into the locking hole 3 of the metal lever 2,
The cylindrical grip 5 made of an elastic material can be fitted and locked to the metal lever 2 so as not to slip out.
Therefore, the cylindrical grip 5 made of elastic material can be fitted and fixed to the metal lever 2 easily and quickly, and when it becomes necessary to replace the cylindrical grip 5 made of elastic material, the metal lever 2 A rod-shaped tool is inserted between the cylindrical grip 5 made of elastic material and the cylindrical grip 5 made of elastic material, and the cylindrical grip 5 made of elastic material is pushed apart so that the locking projection 4 is removed from the locking hole 3. 5 or by cutting the elastic material cylindrical grip 5 with a knife or the like, effects such as being able to easily and quickly remove the elastic material cylindrical grip 5 from the metal lever 2 can be obtained. It will be done.
