Abstract

PROBLEM TO BE SOLVED: To absorb an impact caused when a nail is driven sufficiently and reduce cost by providing a grip cover for cushioning on a grip which is provided and protrudes on a nailing machine main body and providing a plurality of ribs on an inner face of the grip cover. SOLUTION: A grip cover 11 formed by a cushioning material such as rubber is attached to a grip which is provided and protrudes in a nailing machine main body. The grip cover 11 is provided with a plurality of ribs 11a integrally on an inner face thereof, and an end face 11b of the rib 11a comes into contact with the grip and becomes a receive plate. An impact transmitted to the hand of a worker holding the grip due to reaction force generated when a nail is driven is not only absorbed by a material of the grip cover 11 formed by the cushioning material but also the adsorption effect due to its shape is obtained. This is due to the deformation of the rib 11a provided in the grip cover 11. Since the rib 11a can escape into a space 12 provided between ribs when the rib 11a receives an impact, it is readily deformed, and the impact can be absorbed due to this deformation.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a grip cover for a nailing machine.

[0002]

2. Description of the Related Art A nailing machine using compressed air drives a nail into a material to be driven by applying a large impact to the nail, and therefore generates a large reaction force at the time of driving. This reaction force is transmitted as an impact to the hand of the worker holding the grip, and causes discomfort to the worker.

[0003] For this reason, conventionally, the grip of a nailing machine is generally provided with a grip cover formed of a cushioning material such as rubber in close contact with the gripper.
In some cases, a gel-like cushioning material is interposed between the grip and the grip cover as shown in FIG.

[0004]

However, in the case of the former, only the absorption by the material of the grip cover formed of the cushioning material is not enough to absorb the impact transmitted to the hand by the reaction force generated at the time of driving. Did not. In the latter case, the impact is absorbed not only by the grip cover itself but also by the gel-like cushioning material. Therefore, the absorbing effect is enhanced, but the gel-like cushioning material is added. And the problem of high cost and poor productivity arises.

Accordingly, an object of the present invention is to provide an inexpensive gripper for a nailing machine which can sufficiently absorb the impact at the time of driving, in view of the above-mentioned conventional disadvantages.

[0006]

In order to achieve the above-mentioned object, the structure of the present invention has a piston driven by compressed air and a driver integrally mounted on the piston, and the driver slides the piston. In a nailing machine that injects nails, a grip provided for buffering is provided on a grip protruding from the nailing machine body, a plurality of ribs are provided on an inner surface of the grip cover, and an end surface of the rib is in contact with the grip. The present invention provides a grip cover for a nailing machine characterized by being formed as described above.

According to the present invention, it is possible to sufficiently absorb the impact transmitted to the operator's hand due to the reaction force generated at the time of driving the nail, and to add no components for this purpose, and does not affect the assembling workability. A nail cover for a nailer can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a pneumatic driving type nailing machine, in which a cylinder 2 is provided in a nailing machine main body 1, and a piston 3 and a driver 4 integrally attached to the piston 3 slide in the cylinder 2. It is movably provided. As an operation sequence, first, compressed air generated by an air compressor or the like is supplied from a compressed air supply port 6 at the lower end of the grip 5. The supplied compressed air is stored in the air chamber 7 and sent into the cylinder 2 by a valve (not shown) which is opened and closed by a trigger 8. Thereby, the piston 3 and the driver 4 slide, and the nail 9 is moved to the injection section 1.
It starts from 0.

The grip 5 projecting from the nailing machine body 1 has a grip cover 1 made of a cushioning material such as rubber.
1 is attached. 2, a plurality of ribs 11a are integrally provided on the inner surface of the grip cover 11, and an end surface 11b of the rib 11a is formed so as to contact the grip 5 and serve as a receiving surface.

According to the grip cover 11 of the nailing machine of this embodiment, the impact transmitted to the hand of the worker holding the grip 5 due to the reaction force generated at the time of nail driving depends on the material of the grip cover 11 formed of the cushioning material. In addition to absorption, an absorption effect due to the shape can be obtained. This is the grip cover 11
This is due to the deformation of the rib 11a provided on the
When a shock is applied to the member 1a, the member 1a can escape to the space 12 provided between the ribs, so that the member 1a is easily deformed, and the deformation absorbs the shock.

[0011]

As described above, the grip cover of the nailing machine according to the present invention has a plurality of ribs 11a provided on the inner surface of the grip cover 11 formed of a cushioning material. 5 can be absorbed not only by the material of the grip cover 11 but also by the inner surface formed into a deformable shape, that is, the plurality of ribs 11a. Also, since only the ribs are added, the number of components does not increase, and therefore, there is no difficulty in assembling.
