Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tilt test stand for vehicles such as automobiles.

[Prior Art] In automobiles, tilt tests are conducted to test the effectiveness of brakes, etc. The tilt test stand for performing this tilt test has a tilt table pivoted to the base.
There are passageways on both sides of the ramp. Therefore, when the ramp is tilted, the passageway also tilts, making it impossible to go up and down, which limits various operations during the test.

For this reason, there are some devices in which a large number of convex portions are formed in the passage perpendicular to the direction of inclination, but it is difficult and dangerous to ascend and descend.

The present applicant has disclosed in Japanese Utility Model Application Publication No. 1981-6081 a device capable of applying an arbitrary appropriate load to an automobile for an arbitrary period of time by simple operation during a brake test.

[Object of the invention] Therefore, an object of the present invention is to provide a tilting test stand for a vehicle that can be raised and lowered to perform various tasks during a tilting test.

[Structure of the invention] According to the invention, a ramp is pivotally mounted inside a horizontal fixed step, and on both sides of the ramp there are a plurality of treads whose treads are flush with the treads of the fixed step when the ramp is horizontal. The movable steps are pivoted adjacent to each other and two vertical lines passing through the pivot points of all these steps
The points are connected by parallel links parallel to the ramp.

[Operations and Effects of the Invention] Therefore, even if the ramp is tilted, the tread of the movable step is held parallel to the horizontal tread of the fixed step, that is, horizontally, by the parallel ring, and a staircase is formed. As a result, it is possible to easily go up and down the stairs to perform various tasks.

[Preferred Embodiment] When carrying out the present invention, it is preferable to provide safety fences on a vertical line passing through the pivot points of all steps, and to connect the upper ends of these safety fences with handrails parallel to the ramp. In this way, the safety of lifting and lowering and work can be improved.

[Examples] Examples of the present invention will be described below with reference to the drawings.

1 and 2, a fixed step 3 whose tread surface, that is, an upper surface is horizontal, is fixed on both sides of the upper edge of one end in the longitudinal direction of the pit P, and a support shaft is provided inside the fixed step 3. (FIG. 3) A tilting table 1 is pivotally connected via a tilting table 2, so that a vehicle C can be placed on the tilting table 1 and tilted steplessly within a predetermined angle range by means not shown. A large number of movable steps 4 (25 each in the illustrated example) are pivoted adjacent to each other on both sides of the ramp 1 so that their top surfaces are flush with the top surface of the fixed steps 3 when the ramp 1 is horizontal. has been done.

In FIGS. 3 and 4, the movable step 4
is formed into a downward isosceles triangular shape when viewed horizontally, and is pivotally connected to the tilting table 1 by a step shaft 5 on the same horizontal line as the support shaft 2. Note that 14 is a step frame that pivotally supports one end of the step shaft 5.
On a vertical line passing through these support shafts 2 and step shafts 5, link pins 6 and 7 are provided upward and downward, respectively, and these link pins 6 and 7 are connected to parallel links 8 and 9 parallel to the tilt table 1. and vertical link 10
and are interconnected. And link 10
are extended upward to form safety shelves 11, and the upper ends of these safety shelves 11 are connected to handrail pins 12.
They are connected to each other by a handrail 13 parallel to the ramp 1.

Therefore, when the tilting table 1 is tilted to the position shown by the two-dot chain line, the movable step 4 moves to the link pins 6, 7,
The parallel links 8 and 9 lift the top surface horizontally, and these top surfaces form stairs on both sides of the ramp 1. At this time, the oblique sides of the movable steps 4 serve to avoid mutual interference and to increase the stepping distance of the formed stairs. As a result, the worker can easily go up and down the stairs to perform various tasks, and is also safely protected by the safety shelf 11 and handrail 13.

[Summary] As explained above, according to the present invention, stairs are formed using movable steps when the ramp is tilted, making it easy to ascend and descend, and various operations can be performed safely.
