Abstract

Device allowing the rotation of a parked vehicle. This device according to the invention is particularly intended for any person having practical or physical problems for maneuvering on a reduced surface. The invention comprises a mechanical structure consisting of two delimited ramps (2) by chains (17). A system of pivoting wedges (16) allows the stability of the ramps on the ground before positioning the vehicle. Cross members (3) make the connection of the ramps, all on a floating system made up of rubber pads (7). elastic support is linked to a rotation system made up of a ball crown (6). This crown allows the movement of the assembly without constraint. An indexing immobilizes the concept at precise points.

Description

The present invention relates to a mechanized device made of galvanized steel tube and sheet. It is fixed on a flat ground and allows the 360 rotation of a vehicle around an axis perpendicular to the ground.

The special feature of this invention is that it requires very little effort to set in motion in a useful area of 2.5 m radius. This invention can be installed wherever the surface allows and where various maneuvering problems exist.

The invention mainly consists of two access ramps (2), the width and length of which can be adapted on demand. At the ends of these ramps is a system of pivoting wedges 6).

Before the vehicle is mounted, the levers fitted to each are actuated downwards. The blocks thus locked allow the mounted phase of the vehicle and eliminate the radial forces exerted on the ball ring. The ramps at this time are integral with the ground and ready to receive the load.

At the periphery of the ramps, plastic tubes and chains (17) are placed to serve as a benchmark and facilitate access. Once the car is in position on the ramps, the driver descends and unlocks the chocks by raising them.

The concept then rests solely on the ball crown The driver exerts a slight push against his vehicle while following. The whole turns without any constraint. A mechanical indexing (12) with manual action allows the concept to immobilize it in a precise place. Once the maneuver is complete, the shims are put back down manually or with the foot. The car is in the desired direction and ready to go.

A concrete base of 1.20 m squared by 15 cm deep is necessary to support the invention. The fixing is done simply by four screws pegged in the concrete.

Advantage of the invention - eliminates all maneuvers of U-turns - allows to be in the direction of walking to lead to a traffic lane - avoids laborious back steps in paths or small tracks - allows not to turn your head in maneuvers (in particular for the elderly or infirm) - preserves the mechanics and the bodywork by the absence of maneuver. Characteristics of the invention 1) the ramps (2), composed of rectangular steel beams, are produced cut in half to facilitate transport as well as production. They are covered with a tear-type sheet, with a slope at the end to facilitate the ascent of the vehicle. These ramps can also be made of a light metal and in one piece. They are fixed on the crosspieces (3) via angles (15) - fig.4.

2) the shims (16) are made of folded sheet metal hinged at the end of the ramps by an axis passing through the beams fig.6.

3) the crosspieces (3) and side member (4) are composed of three UAP steel beams. They make it possible to make the connection between the rotation system and the two ramps via the fasteners (5) - fig.5.

4) elastic supports (7): these standard commercial studs are 6 in number, with a diameter of 80 mm, a height of 40 mm and have an axial load of 600 kg each. They make the connection between the crown (6) and the rest of the mechanical structure. They also have the role of absorbing the radial forces exerted on the crown - fig. 3. 5) the ball crown (6), an essential element of this invention, is distributed by various catalogs of specialized tools, with different diameters and loads. The one chosen for this application is a crown of 1 meter in diameter, accepting an axial load of 3.5 tonnes. It is protected by a sheet (14) in the center of the structure - fig. 1.

6) The indexing (12) of the barrier foot lock type is actuated manually. Several points in the ground can stop the evolution of the device in different positions - fig. 3.
