Problems solved by technology

[0004] The system requires separate cables for the folding and unfolding of the ramps and for the movement of the stringers, which complicates the walkway structure
In addition, the floor of the walkway may suffer from insufficient rigidity and safety for the user in the deployed position of the walkway

Embodiment Construction

[0027] As can be seen from Figures 1 to 7, the ramp of the present invention is intended to fit in the hole of a door 1 mounted on a frame, of which a vertical column is shown in Figures 1, 3 and 4, one of which The vertical column mark 2, the door 1 is hinged between two vertical columns by the crank arm 4 according to the rotation axis 3.

[0028] The evacuation ramp is fitted behind the door 1 between the vertical columns 2, the ramp consists of two frames marked 5 and 6, said frames are connected to each other via one of the short sides by a hinge 7, the frame 5 additionally by a hinge Fitted between the posts 2 is a pin 8 parallel to the hinge pin 7 of the two frames and the hinge pin 3 of the door 1 .

[0029] Frames 5 and 6 can swing between a folded position as shown in FIG. 1 and an unfolded position as shown in FIG. Between the columns 2, in said deployed position, the frames 5 and 6 extend to define a passage surface.

[0030] The frames 5 and 6 are connected by s...

Abstract

This invention relates to a folding ramp for vehicle access, made up of two frames (5 and 6), linked to one another by means of a hinge (7) and with the door frame through a hinge (8), which frames can shift between a folded position, folded upon the door, and a deployed position, each frame being made up of two longitudinal beams (15 and 16) and an intermediate floor formed by a moving section (17) and at least one fixed section (18), the moving section (17) being able to shift between a position superimposed with the fixed section (18) and another extracted position, in which it is extended with said fixed portion (18).

Description

technical field [0001] The present invention relates to a folding ramp for car access, especially for passenger transport cars, if necessary, as an evacuation ramp; although it can also be used for loading and unloading goods. [0002] More specifically, the ramp of the present invention is of the type that fits inside the door, in the passage hole of the door, and consists of two rectangular frames joined to each other by one of their short sides, and through which The free short side of one frame is joined to the lower part of the door opening, and the two frames are swingable between a folded position in which they remain against each other and against the door opening frame, and an unfolded position in which They are aligned in position and extend outwards to define a passable path, each frame is composed of two stringers and an intermediate floor, and the two frames are connected to the door frame by slings connected to A collecting drum with a brake fitted to the frame....
