Abstract

(57) [Summary] [Purpose] The mounting position of the rear bumper of an ordinary vehicle is stipulated by the Road Transport Vehicle Law, but when driving on public roads, make it a height that complies with the law, and the rear bumper at the work site is not disturbed. In some cases, it will provide a lift-type rear bumper that moves upward. [Structure] A shaft (4) is formed by expanding and contracting a stay (3) rotating around a bearing (2) mounted on a frame (1) and a hydraulic cylinder and a piston (5) mounted on a shaft (4).
Is characterized by moving up and down.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rear bumper for a standard automobile that is lifted and lowered.

[0002]

[Prior art]

 Conventionally, when the rear bumper mounting position of an ordinary vehicle is low and it is a hindrance to work, the rear bumper mounting position was raised or removed.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (A) The mounting height of the rear bumper of an ordinary vehicle is determined by the safety standards of the Road Transport Vehicle Act, and if the mounting height is increased or removed, it may result in a poorly maintained vehicle that is in violation of the Road Transport Vehicle Act. there were. (B) When a car crashes into the car from behind If the rear bumper is installed at a high position or the rear bumper is removed, the car cannot be prevented from entering.

[0004]

[Means for Solving the Problems]

 A hydraulic cylinder and a piston (5) are attached to a stay (3) and a shaft (4) which rotate around a bearing (2) attached to the frame (1).

[0005]

[Work]

 The shaft (4) is moved up and down by rotating the stay (3) and the shaft (4) around the bearing (2) attached to the frame (1).

[0006]

【Example】

 The shaft (4) is moved up and down by expanding and contracting the stay (3) and the hydraulic cylinder and piston (5) mounted on the shaft (4) around the bearing (2) attached to the frame (1).

The present invention has the above-mentioned structure, and when a normal vehicle runs on a public road, the hydraulic cylinder and piston (5) are extended (compressed) and the shaft (4) is used in a low position. To do. If the rear bumper is a hindrance at the work site, etc., use the hydraulic cylinder and piston (5) with the shaft (4) in a high position by contracting (extending) it.

[Effect of device]

 If an ordinary automobile keeps the rear bumper in a low position when traveling on public roads, it does not violate the safety standards of the Road Transport Vehicle Law, and therefore does not become a poorly maintained vehicle. If the rear bumper is a hindrance at the work site, etc., it is easier to work by raising the position of the rear bumper.
