The purpose is to provide a shock absorber. [Structure] A shock absorber A having a horizontally long rectangular parallelepiped hollow box body composed of a substrate 1 and a lid body 2 filled with a shock absorbing material 3,
It is hinged to the corner post 4 at the rear of the vehicle, and the opposite side can be locked to the corner post 4 by the locking device 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shock absorber mounted to a vehicle rear portion of a work vehicle on a road where a special work vehicle, a van type vehicle, or the like has a high risk of collision, especially on a highway.

[0002]

[Prior art]

 Vehicles used for work on highways and general roads such as erection, repair, cleaning, and spraying are always exposed to rear-end collisions and contact during work. Therefore, it is required to minimize the damage in case of an accident. Conventionally, a rear bumper is mounted on the rear part of the chassis frame as a shock absorber of a vehicle as shown in Fig. 5, but this does not function sufficiently as a safety device on a highway. Also, fixed type shock absorbers have already been known. However, since the shock absorber is a fixed type, it is not easy for an operator to get in and out of the bed. For this reason, there is no choice but to ride on the shock absorber and enter the cargo bed, but the shock absorber is deformed at this time, which is not preferable.

[0003]

[Problems to be solved by the device]

 In view of the problems of the prior art, it is necessary to provide a shock absorber that secures safety in the case of a rear-end collision of a work vehicle that is running or stopped on the road and at the same time reduces the impact of the rear-end collision vehicle. In addition, it can be opened and closed easily with one-touch operation and can freely enter and exit the back of the vehicle from the back of the vehicle, it does not hinder work, it does not deform even when riding on it, but it can be provided at low cost It is intended to provide a rear shock absorber.

[0004]

[Means for Solving the Problems]

 A shock absorber A, which is a horizontally long rectangular parallelepiped hollow box made of a substrate 1 and a lid 2 and is filled with a shock absorbing material 3, is hingedly connected to a corner post 4 at the rear of the vehicle, and the opposite side is used as the corner post 4. On the other hand, it is possible to lock with the locking device 7.

[0005]

[Action]

 A large shock absorber A mounted on the rear part of the vehicle so as to extend over substantially the entire width of the vehicle can protect the work vehicle on the highway from a collision. When the worker goes in and out of the loading platform of the vehicle, remove the lock device 7 of the shock absorber A and rotate 90 ° around the hinge 6 to open and close the door at the rear of the vehicle. it can.

[0006]

【Example】

 FIG. 1 is a perspective view of a van type vehicle in which a shock absorber A according to the present invention is mounted on a rear portion. As shown in FIG. 2, the shock absorber A is composed of a horizontally long rectangular parallelepiped hollow box surrounded by a substrate 1 and a lid 2 fixed to the substrate 1, and a cushioning material 3 filled in the box. Has been done. The cushioning material 3 of the cushioning device A is, for example, a soft or rigid polyurethane foam, a synthetic resin foam such as polystyrene foam, a mixture of these resins, a hollow rubber or a hollow soft resin, and other cushioning material, Alternatively, it is made of in-situ foamed cushioning material.

The shock absorber A of the present invention has an extremely large outer dimension, and this configuration can protect the vehicle in a wide range. However, from the design point of view, the edges of the box may be curved. The outer diameter is changed according to the vehicle size, but the width is designed according to the vehicle width. For example, in the case of a 2-ton vehicle, if the width is 1500 mm, which is almost the same as the vehicle width, the vertical width is 700 mm and the thickness in the front-rear direction is 600 mm.

The shock absorber A has one side of the base plate 1 rotatably attached to a rear corner post 4 of the vehicle and an attachment member 5 extending downward by a hinge 6. The opposite side of the hinge 6 is locked by the locking device 7.

As shown in FIG. 4, the lock device 7 is composed of a rod 8 horizontally protruding from the base plate 1 of the shock absorber A, and a locking member 9 attached to the corner post 4 side. When locking, the handle 8 is operated on the rod 8 and the locking member 9 is engaged. As the locking member 9, for example, a dump tail gate (trade name) manufactured by Nippon Bodoku Parts Industry Co., Ltd. is used. This makes it possible to attach / detach with one touch, and it is easy for an operator to enter and exit the body with a luggage carrier.

A steel plate or stainless steel is used for the base plate 1 and the lid body 2 of the shock absorber, and the foaming ratio and the compression elasticity of the recovered heat insulating material and the shock absorbing material are appropriately selected for the inner filling in the box body. This makes it possible to use combined recycles, which is also suitable from an environmental perspective. In the shock absorber thus constructed, one side end of the lid body 2 is pivotally supported by the corner post 4, so that it is opened 90 ° from the closed position in FIG. 3 when entering or leaving the luggage carrier.

[0011]

【effect】

 When the shock absorber of the present invention is installed, the shock can be effectively absorbed by the large box-type shock absorber even when the vehicle is hit by a high-speed vehicle, so that the occupant can be protected together with the vehicle and damage to the other party can be prevented. it can. Further, since the shock absorber can be opened to one side by removing the lock device, the operator can easily enter the luggage carrier.
