Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gate cushion structure for a truck in which a rear gate and side gates can be opened and closed.

(Prior Art) A conventional gate cushion structure in this type of truck is constructed as shown in FIGS. 5 and 6.

That is, as shown in FIG. 5, a rear cross sill c of a truck equipped with an openable and closable rear gate a and a side gate b has a gate for the rear gate on its rear surface d that absorbs the shock when the rear gate a is opened and closed. A gate cushion g for the side gate is attached to the side surface f of the cushion e, which absorbs the shock when the side gate b is opened and closed.

The gate cushions e and g are made by baking a washer i onto a rubber body h, as shown in FIG.
It is attached to the steel plate k of the rear cross sill c by tapping screws j.

(Problems to be Solved by the Invention) However, according to the above-mentioned conventional example, a gate cushion e for the rear gate and a gate cushion g for the side gate are required separately, which increases parts cost and makes installation difficult. There is a problem that the number of man-hours increases and the installation cost also increases.

Also, attach the gate cushions e and g with the tapping screws j.
Since the washer i and the steel plate k of the rear cross sill c come into contact with each other, there is also the problem of rust formation.

(Means for solving the problem) In order to solve the problem of increased parts cost and installation work cost in the conventional example, the present invention is equipped with a rear gate and a side gate that can be opened and closed, and a rear gate and a side gate are provided on the rear cross sill. A truck equipped with a corresponding gate cushion, in which gate cushions that serve as a rear gate cushion member and a side gate cushion member are installed at both end corners of the rear cross sill, and at both end corners of the rear cross sill. , mounting holes are provided on each of the rear and side surfaces, and an engaging protrusion that engages with each of the mounting holes is provided on the mounting surface side of the L-shaped gate cushion, which is entirely made of a soft elastic material such as rubber. and the gate cushion is attached to the rear cross sill by engaging the engagement protrusion with the attachment hole.

(Function) According to the present invention, since the gate cushions that serve as both the rear gate cushion member and the side gate cushion member are attached to both end corners of the rear cross sill, the number of gate cushion parts can be reduced.
And, as a result of being able to halve the installation work, it is possible to reduce parts costs and installation work costs. In addition, mounting holes are provided on the rear and side surfaces of both end corners of the rear cross sill, and each of the mounting holes is provided on the mounting surface side of the L-shaped gate cushion, which is entirely made of a soft elastic material such as rubber. The gate cushion is installed on the rear cross sill by providing an engaging protrusion that engages and using the rubber elasticity of the gate cushion to engage the engaging protrusion with the mounting hole, so that the gate cushion can be easily installed. Moreover, it can be installed firmly and there is no risk of rust forming at the gate cushion attachment part.

(Embodiment) In the embodiment of the present invention shown in FIGS. 1 to 4, 1 is a rear gate that can be opened and closed, 2 is a side gate that can be opened and closed, and 3 is a rear cross sill.

At both end corner portions of the rear cross sill 3, keyhole-shaped attachment holes 6 and 7 are provided in the rear surface 4 and side surface 5, respectively. Small hole protrusions 6a and 7a of each mounting hole 6 and 7 are formed on the corner side.

The gate cushions 8 are attached to both end corners of the rear cross sill 3 so as to serve as both a rear gate cushion member and a side gate cushion member. The gate cushion 8 is made of rubber and is integrally molded into the shape shown in FIG. 1, and is L-shaped. Coupling protrusions 9 and 10 are provided.

A recess 1 is provided at the corner of the gate cushion 8.
1 is provided, and engagement grooves 9a, 10a are formed around each engagement protrusion 9,10. Further, the distance l between the engaging protrusions 9 and 10 of the gate cushion 8 in the natural state shown in FIG. 1 is slightly smaller than the mounting interval L between the mounting holes 6 and 7 of the rear cross sill 8. Therefore, when attaching the gate cushion 8 to the corner of the rear cross sill 3,
It is necessary to hold both ends of the gate cushion 8 and expand it using the tension rubber elasticity, and then engage the engaging protrusions 9 and 10 into the mounting holes 6 and 7, and then release your hands. When the gate cushion 8 is restored, its engaging protrusions 9 and 10 are firmly engaged with the mounting holes 6 and 7. The present invention can be configured in various ways other than those shown in the above embodiments.
For example, the gate cushion 8 can be made of a soft elastic material other than rubber, such as a soft synthetic resin. Further, in the above embodiment, the L-shaped gate cushion 8 made entirely of rubber is used, and the engaging protrusions 9 and 10 are provided on the mounting surface side, thereby avoiding surface contact between metals and preventing the problem of rust. However, the structure and attachment means of the gate cushion 8 are not limited to this.

(Effects of the invention) Since the invention has the above-mentioned configuration and operation, it is possible to reduce parts costs and installation work costs.
It is also possible to provide a track gate cushion structure that is free from rust.
