THE SHIM, ACCORDING TO THE INVENTION, IS REALIZED IN SUCH THAT IT CONSISTS OF AN INTERMEDIATE FLAT ELEMENT 1, A FLAT SUPPORT ELEMENT MOUNTED 4 ON THE FIRST AND A SUPPORT ELEMENT 5 THE THREE ELEMENTS THAT CAN ROTATE AROUND AXES 2 , 3. THE FLAT SUPPORT ELEMENT 4 IS INCLINED FORMING AN ACUTE ANGLE - PREFERENCE LESS THAN 45 - TOWARDS THE INTERMEDIATE FLAT ELEMENT 1 AND LIES ON THE AREA OF THE SUPPORT ELEMENT 5. FINALLY, THE WEDGE IS EQUIPPED WITH A RELEASABLE BLOCKING ELEMENT 6 WHICH PREVENTS ANY MOVEMENT OF THE FLAT SUPPORT ELEMENT.

Description

FOLDABLE HOLDER TO PREVENT ANY BODY MOVEMENT

  ROLLERS, ESPECIALLY VEHICLE WHEELS

  The invention relates to a chock by means of which it is possible to prevent the displacement of rolling bodies, in particular vehicle wheels, said chock, when not in use, which can be stored in a state requiring little space. 'space. To prevent the displacement of bodies capable of rolling or moving, it is common practice to generally place any object on both sides of this body in the possible direction of movement. The most frequent characteristic solution consists of a wedge commonly spread in the form of a wedge adapted to the wheels of the vehicle. In general, the wedges thus mentioned

  are made of wood, metal or plastic.

  In most cases, the objection made with regard to known wedges is the fact that they are relatively bulky and heavy. This disadvantage is important in particular for passenger vehicles in which the luggage compartment is relatively small, so as a general rule passenger vehicles are not equipped with chocks, although, during the most common daily activity or the changing a wheel, the

  wheel chocking is advantageously advised.

  Therefore, the object of the present invention

2585'313

  consists in making a chock which is easy to transport and store and which at the same time satisfactorily prevents any movement of the vehicle wheels or

other bodies.

  The invention is based on the known fact of the possibility of assembling a few flat elements to produce a wedge which can serve the purposes sought and of being compact when these flat elements are

placed on top of each other.

  The invention therefore relates to a foldable wheel chock which has an intermediate flat element, a flat support element fixed to the first and a flat support element, these elements being able to rotate each about an axis, the flat element support inclining at an acute angle advantageously less than 45.degree. - towards the intermediate flat element and pressing on the edge of the flat support element, and being furthermore provided with a releasable blocking element which prevents any displacement

of the flat support element.

  In an advantageous embodiment of the shim according to the invention, the two axes of rotation of the elements

dishes are parallel to each other.

  Another advantageous embodiment of the shim according to the invention is arranged so that the flat support element is shorter than the other two

flat elements.

  Finally, an advantageous embodiment of the wedge according to the invention provides a solution by which

  the flat support element and the flat support element -

  considered both from the intermediate flat element form an internal angle of 90 'or smaller, a flange being arranged on the opposite end & the axis of rotation of the flat support element, this flange being inclined towards the intermediate element and the edge of the support element coming to bear on

the inclination of this ledge.

  The wedge according to a preferred embodiment of the

  vention is described in more detail below with reference to the accompanying drawing. In this drawing: FIG. 1 is a side view of the wedge according to the invention; Figure 2 is a top view of the wedge; and Figure 3 is a side view of the wedge in the folded state. On the wedge shown in Figures 1 and 2, the intermediate flat element 1 has been cut and stamped from a sheet of steel. At the two ends, articulated parts are respectively produced, the axes 2, 3 of which are articulated on the one hand with the flat support element 4 and

  on the other hand with a flat support element 5.

  On the end of the flat support element 4 opposite the axis 3, a flange 6 has been arranged in such a way that said flange 6 is inclined against the intermediate flat element 1. By this flange 6, or by the inclination adjacent to this rim, the flat element 4 rests on

  the edge of the support element 5.

  In view of the fact that the wedges guarantee total reliability only if they are placed in a corner between the roadway and the vehicle wheel, the internal angle o formed by the intermediate flat element 1 and the flat supporting element 4 is advantageously an angle

  acute, preferably less than 45.

  As is clear from FIG. 1, the edge of the flat support element 5 practically follows the inclination situated next to the rim 6. This measurement is essential so that the flat support element 5 cannot move or in the direction of axis 3 nor in the opposite direction. This stable position can be ensured by choosing for the internal angle formed by the flat reinforcing element 5 and the flat supporting element a value of

or even smaller.

  According to the choice of this angle, we obtain the relation

  reciprocal between these different flat elements.

  The use of the specified shim is obvious. The chock is placed on the ground in the state shown in Figure 1, and pushed under the wheel 7. The chock prevents the

wheel movement.

  If the wedge is not used, the flat elements can be folded over each other, around axes 2 and 3, and the small baggage shown on

Figure 3.

  The flat elements used to achieve the

  wedge shown in Figure 1 are simple plates.

  If higher resistance shims are required,

  it is possible to reinforce these plates with ribs.

  Finally, for the correct rule, it should be noted that neither the flat support element nor the intermediate flat element require a preferred position, this means that the chock can be placed under the wheel even when placing the element.

support plate against the ground.

  It is also possible to make the shim in a different way compared to that shown in the drawing. It is possible, for example, to have the flat support element perpendicular to the axis of

  the flat support element and the intermediate flat element.
