Abstract

PROBLEM TO BE SOLVED: To provide a step for getting on and off a truck capable of absorbing collision energy. SOLUTION: A fragile members 9 axially compressible and deformable in the longitudinal direction of a vehicle are mounted through the brackets 7, 8 on the left and right step supports 5, 6 for fixing a getting on and off step 2 fixed to a rear part of a bumper of a door lower part at a cab side, and one of the brackets 8 is provided with an engagement part 8a engaged with a front wheel 3 in the collision for controlling the outward displacement of the step.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step for getting on and off a vehicle provided on a cab of a truck.

[0002]

2. Description of the Related Art As shown in FIG.
A step 2 for getting on and off is fixedly provided behind the bumper 4 below the side door.

[0003]

Since absorbing the collision energy as much as possible in the event of a vehicle collision leads to the safety of the occupant, it has been considered to absorb the energy in each component.
By the way, the step 2 for getting on and off provided on the cab 1 is sandwiched between the bumper 4 and the front wheel 3 and escapes to the outside of the front wheel 3 as shown by a dotted line in FIG. It has no function of absorbing collision energy.

An object of the present invention is to provide a step for getting on and off a truck capable of absorbing collision energy.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, there is provided a step for mounting and dismounting which is fixed below a side door of a cab of a truck and behind a bumper. A fragile member capable of being axially compressed and deformed in the vehicle longitudinal direction is provided on the left and right step supports via brackets.

In the step for getting on and off fixedly behind the bumper below the side door of the cab of the truck, axially compressively deforming in the longitudinal direction of the vehicle via brackets on left and right step supports fixing the steps. A possible fragile member is provided, and the bracket is provided with an engaging portion that engages with a front wheel at the time of a collision to restrict outward displacement of a step.

The fragile member capable of being axially compressed and deformed in the longitudinal direction of the vehicle is a bellows-like cylindrical member.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a step 2 for getting on and off the truck is fixed below the side door of the cab 1 behind the bumper 4 by a step support.

As shown in FIGS. 2 and 3, the present invention provides a weak member 9 which is axially compressively deformable in the longitudinal direction of a vehicle via brackets 7, 8 on left and right step supports 5, 6 on which the step 2 is fixed. Is provided.

[0010] Of the brackets 7 and 8 holding the fragile member 9, one of the brackets 8 facing the front wheel 3 is provided with an engaging portion 8a that engages with the front wheel 3 at the time of collision.

The fragile member 9 capable of axially compressively deforming in the longitudinal direction of the vehicle is suitably a bellows-shaped cylindrical member. However, a solid shaft or the like having a fragile portion formed by notches or the like in a bellows-like plate member or a shaft is in the axial direction. Any member can be used as long as it is axially compressively deformable and buckles when impact energy acts on the member.

Since the present invention has the structure described above, step 2 is sandwiched between the bumper 4 and the front wheel 3 when a front or rear collision occurs. At this time, the fragile member 9 is axially compressed and deformed in the vehicle front-rear direction to absorb the collision energy.

In addition, the step 2 comprises the step of making the bumper 4 and the front wheel 3
The engagement portion 8a provided on one of the brackets 8 holding the fragile member 9 when it is sandwiched between the front wheel 3 and the front wheel 3 as shown by the phantom line in FIG. As a result, in Step 2, escape to the outside of the front wheel 3 is regulated,
The function of absorbing the collision energy by the fragile member 9 is further improved.

[0014]

As described above, according to the present invention, the step of getting on and off the truck is equipped with a collision energy absorbing function having a simple structure, so that the safety of the occupant in the event of a vehicle collision can be ensured. . In addition, since the structure is configured by adding to the conventional steps for getting on and off,
This has the advantage that it can be realized at low cost without significantly modifying the steps.
