JP2002265193A - Noise preventing type fork - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate failures that a large noise is generated because a fork plays when a forklift travels on an uneven surface of a road and violently collides on an abutting surface with a board after the fork floats from the board, the fork becomes difficult to move to left and right sides in the fork reduced in gap and it takes labor and time to loosen the fork using a stopper bolt when using the fork. SOLUTION: This noise preventing type fork is characterized by mounting a cushioning material 3 using resin or rubber in the gap 4 of the abutting surface of the fork 1 of the forklift and the mounting board 2 by fitting or adhering.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fork rattle prevention in a forklift.

[0002]

2. Description of the Related Art In the prior art, as shown in FIG. 7, a fork is mounted by directly hooking a hook on a board to be mounted. In this installation, both are made of iron, so in order to reduce the collision noise, the gap for rattling between the fork and the board was reduced, or a stopper bolt was attached to the fork to sandwich the fork.

[0003]

However, in the above-mentioned conventional structure, when the forklift travels on an uneven surface of a road or the like, the fork rattles, and after the forklift floats off the board, it collides violently at the contact surface with the board, resulting in a large collision. It was generating noise. Also, with a small gap, when moving the fork to the left and right, it becomes bitter, and those using stopper bolts
It took time to loosen when moving. It is an object of the present invention to eliminate such disadvantages.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a resin or rubber or the like is used in a gap between a contact surface between a fork of a forklift and a mounting board. The shock-absorbing fork is characterized in that the shock-absorbing material is fitted or attached.

[0005] With the above-described structure, the gap is reduced and the magnitude of the impact noise is reduced. In addition, since the impact is made via the cushioning resin or the like, the metal noise is reduced. Will be improved.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings. FIG. 1 is a side view showing a noise prevention type fork to which a cushioning member according to the present invention is attached, and FIG. 2 is a perspective view of a fifth embodiment in which a cushioning member is attached to a board. Further, FIGS. 3 to 6 show first to fourth embodiments of the shape of the cushioning material which can be fitted and attached to the lower hook of the fork.

In FIG. 1, a rubber or resin cushioning material 3 is applied to a groove of a hook 11 provided on the lower side of the fork 1 to provide a gap between the fork 1 and the lower guide plate of the board 2. 4 so as to prevent direct collision between irons.

In FIG. 2, a rubber or resin cushioning material 3 is adhered to a portion to be a contact surface between the fork 1 and the lower guide plate of the board 2 by gluing or screwing, so that the irons are directly connected to each other. No collisions occur.

Therefore, when the forklift travels on an uneven surface of a road surface, the fork 1 is prevented from rattling and violently colliding with each other on the contact surface of the board 2 after floating from the board 2, and no loud noise is generated. It has become.

In addition to the effect of suppressing noise, the material used as the cushioning member 3 reduces the sliding resistance when the fork 1 is moved right and left depending on the size of the cargo to be loaded and unloaded, thereby enabling smooth operation. There are also advantages that can be achieved.

In FIG. 1, as examples of the shape of the cushioning material 3 attached to the fork 1, FIG. 3 shows a U-shape 31, FIG. 4 shows a straddle 32, FIG. 5 shows a window 33, and FIG. Although 34 is shown, it may be selected from the viewpoints of stability at the time of attachment, production, easy supply, and the like.
