Abstract

The invention relates to a self-winding disintegration belt (10) for a vehicle (V) having at least one wheel (R1), said dishing belt having a main driving portion (12) and a baiting tab of rolling (20) which is attached to one end of the main driving portion (12) by a hinge connecting portion (22) arranged to lower the rolling start tab relative to the main driving portion whereby the rolling start tab can be positioned at the bottom of a rut (O) in which said vehicle wheel is bogged down.

Description

Background of the invention

The present invention relates to the field of devices for disinhibiting wheeled vehicles, such as cars or trucks.

It is known that a wheeled vehicle can become bogged down in the ground. When the vehicle is bogged down, at least one of its driving wheels skates and digs the ground forming a rut in which it sinks. The rut has the shape of a recess formed in the ground. The wheel is then locked in the bottom of the rut so that the vehicle can not move forward.

A stagnant situation can occur in sand or mud. This is known as silting or bogging.

The désenlisement device according to the invention then allows to desamble or déschourber, depending on the situation, the vehicle prisoner soil.

To désenliser a vehicle, it is known to use rigid plates, plastic or metal, which is placed in the rut under the wheel drive bogged down. The wheel then finds a support allowing it to roll without skating and advance on the plate, thanks to which the vehicle can emerge from the rut.

A disadvantage of such a plate is its size. To solve this problem, rigid plates are known consisting of several plate portions that are fixed to each other to form the plate. If such a dislodging device has a smaller footprint, it has the disadvantage of requiring a long assembly and disassembly time. In addition, the plate has a certain fragility. Finally, if the plate portions are not properly cleaned after use, it may be difficult to reassemble the plate, for example, because of the sludge that is lodged between the plate portions.

Object and summary of the invention

An object of the present invention is to provide a stopping device remedying the aforementioned drawbacks.

To do this, the invention relates to a self-winding disengaging mat for a vehicle having at least one wheel, said dishing carpet having a main portion of rolling and a rolling primer tab which is attached to the one of the ends of the main portion of rolling by a hinge connection portion arranged to lower the rolling starter tab relative to the main portion of rolling, whereby the rolling starter tab can be positioned at the bottom a rut in which said wheel of the vehicle is bogged down.

A first advantage of the disliner mat according to the invention is its small size when in the wound position, thanks to which it can then be easily transported. In addition, it does not require assembly, or else a very simple assembly in the embodiment in which the rolling primer tab is removable from the main driving portion. The carpet is also much lighter and easier to handle than a lot of metal desalination plates.

When the rolling start tab is lowered relative to the main driving portion, the rolling start tab extends in a plane which extends under the plane of the main driving portion. The roll initiation tab can be brought to the bottom of the rut while the main driving portion remains substantially parallel to the ground, above the rut.

It is therefore understood that the rolling start tab, and possibly the hinge connection portion, form a slope, inclined relative to the main portion of rolling, allowing the wheel stuck to disengage the rut. Thanks to the invention, the stuck wheel, for example one of the driving wheels, hooks the rolling starter tab, rolls on the rolling starter tab and exits the rut by climbing on the main portion rolling. The vehicle then rolls over the main driving portion, preferably until the other wheels are also out of the ruts also rolling on the rolling start tab and the main driving portion.

Advantageously, the rolling primer tab is flexible whereby it can be easily inserted under the stuck wheel.

According to one embodiment, the hinge connection portion is a hinge directly connecting the rolling start tab to the main driving portion.

According to a preferred embodiment, the hinge connection portion is a flexible portion connecting the rolling primer tab to the main driving portion. The flexible portion is then arranged to pivot with respect to the rolling start tab, and with respect to the main driving portion, whereby the rolling start tab can be lowered relative to the main driving portion. so that the tongue extends in a plane below that of the main portion of rolling.

According to a particularly advantageous aspect of the invention, the rolling primer tab has a width substantially smaller than the width of the main driving portion.

An interest is that the rolling start tab goes down in the rut while the main portion of rolling, wider, is supported on the ground, out of the rut, remaining substantially parallel to the ground, and without slipping inside the rut thanks to its width substantially greater than that of the rut.

Such an arrangement helps to facilitate dislodging of the vehicle.

Another advantage of having a tab having a small width compared to the width of the main portion of rolling is that the primer tab can be more easily placed by the user under the wheel bog, which then facilitates the tire grip and dislocation of the wheel.

Preferably, the rolling primer tab has a width of between 15 cm and 40 cm. Such a range of widths corresponds substantially to the average range of vehicle wheel widths.

According to a preferred embodiment, the hinge connection portion is flexible. Of interest is that the connecting portion then forms a curved slope connecting the rolling primer tab to the main portion of rolling, which has the effect of improving the grip of the tire which is partially wrapped by the tongue of primer and connection portion.

Advantageously, the hinge connection portion has a first end edge connected to the main driving portion and a second end edge connected to the rolling start tab, the width of the first end edge being greater than the width of the second end edge. This reduction in width, between the main portion of rolling and the starting tab rolling, improves the strength of the hinge connection portion.

According to an advantageous embodiment, the main portion of rolling has a length substantially greater than the length of the rolling start tab. This allows the vehicle to gain momentum after the stuck wheel has come out of the rut, so that the other wheels can also cross the rut. This limits the risk of the vehicle getting bogged down again near the rut. The primer tab has a length necessary and sufficient for the wheel to cross the rut and climb on the main portion of rolling.

Preferably, the rolling primer tab has a length of between 30 cm and 70 cm. Still preferably, but not exclusively, the main portion of rolling has a length of between 1 meter and 3 meters.

According to an advantageous aspect of the invention, to facilitate the attachment of the tire of the wheel bogged, the rolling start tab has an upper face provided with crampons. These crampons engage in the tire to prevent the wheel from slipping on the rolling start tab.

The crampons are preferably, but not exclusively, made of metal inserts projecting from the upper face of the rolling start tab. However, other forms of crampons can be provided.

To further improve the adhesion of the wheel on the disengaging belt, the main portion of rolling and / or the hinge connecting portion also comprises an upper face which is preferably provided with crampons arranged in the continuity of the crampons of the tongue starting taxi.

Advantageously, at least the rolling primer tab comprises a plurality of transversely extending stiffening elements. An interest is to stiffen the primer tab to prevent it from creasing under the wheel. It is therefore understood that this makes it possible to further improve the efficiency of the disinhibiting carpet. According to a preferred variant, the main portion of rolling is also provided with transverse stiffening elements.

Alternatively, the rolling primer tab is detachable from the main portion of rolling, allowing easy replacement in case of damage to the tongue.

Advantageously, the main running portion and the rolling primer tab consist of a textile covered with a polymer layer, preferably an elastomer. Such a material has the advantage of being flexible, resistant and lightweight. The polymer layer is preferably provided with imprints to further improve tire grip. According to another variant, the crampons are protuberances of the polymer layer.

Detailed description of the invention

In FIG. 1, there is illustrated a vehicle V which is bogged down in the sand S. In this example, the vehicle V comprises a drive wheel before RI which is bogged down at the bottom of a rut O. This rut O has formed in the sand because of the slippage of the drive wheel before RI.

To desenlise, and more precisely to remove the vehicle V, is used a de-liner carpet 10 according to the present invention. More specifically, the disliner mat 10 is used in this example to desalt the drive wheel before RI by pulling it out of the rut O.

The disliner mat is disposed forward of the drive wheel before RI.

As will be explained in more detail below, the RI front drive wheel hooks on the sink mat and rolls on it, thereby clearing the RI wheel from the rut.

The disliner mat 10 according to the invention will now be described in more detail with reference to Figures 2 to 5.

The disliner mat 10 has a longitudinal direction D and a transverse direction T. The disliner mat 10 comprises a main rolling portion 12 which has a length L1, considered in the longitudinal direction D, and a width 11, considered in the direction transverse T.

In this nonlimiting example, the length L1 of the main portion of rolling is of the order of 2 meters, while its width 11 is of the order of 1 meter.

As can be seen in FIG. 3, the main portion of rolling has a substantially rectangular shape whose four corners are, in this example, provided with orifices 14 intended to receive fasteners 16 making it possible to fix the désénlisement mat 10 on the ground S.

The main portion of rolling 12 comprises a plurality of stiffening elements 18 constituted, in this case, metal bars which extend along the width of the main portion of rolling. These stiffening elements have the effect of stiffening the main portion of rolling in its transverse direction to prevent it from sagging during the passage of the vehicle.

As shown in FIG. 3, the desegination belt 10 further comprises a rolling primer tab 20 which is attached to one of the longitudinal ends 12a of the main driving portion.

In this example, the rolling primer tab 20 has a substantially rectangular shape. It is specified that, without departing from the scope of the present invention, the rolling primer tab 12 could have a different shape, for example a slightly curved free end.

The rolling primer tab 20 has a length L2 considered in the longitudinal direction D and a width 12 considered in the transverse direction T.

According to a particularly advantageous aspect of the invention, the width 12 of the rolling primer tab 20 is substantially smaller than the width 11 of the main driving portion 12, so as to be easily positioned in the rut O.

In this example, the width 12 of the rolling primer tab 20 has a width of about 25 centimeters.

In practice, the width 12 of the rolling start tab is chosen to be slightly greater than the width of the vehicle wheel. We can choose a width between 15 and 40 centimeters.

It is also noted that the length L1 of the main rolling portion 12 is substantially greater than the length L2 of the roll initiation tab.

An interest is to allow the wheel that was stuck to roll a long enough distance to ensure that the rear wheels cross the rut in turn.

Furthermore, the rolling primer tongue 20 also comprises stiffening elements 24 which extend transversely along its width, so as to stiffen the tongue in its transverse direction so as to prevent it from wrinkling or sliding under the wheel. These are still rigid bars, for example metal.

According to the invention, the rolling primer tab 20 is fixed to the end 12a of the main driving portion 12 by a hinge connection portion 22. This connecting portion 22 is arranged to lower the primer tab of rolling 20 relative to the plane of the main portion of rolling 12.

In this example, the hinge connection portion has a trapezoidal shape, its large base being constituted by a first end edge 22a connected to the main rolling portion 12, while its small base is constituted by a second edge of end 22b connected to the rolling start tab 20.

In this example, the hinge connecting portion 22 is articulated with respect to the main portion of rolling and relative to the rolling start tab, respectively about pivot axes XI and X2, whereby the tongue roll initiation can be lowered relative to the main driving portion.

In this example, the hinge connection portion 20 is flexible, as is the main rolling portion 12 and the rolling primer tab 20.

This flexibility allows the disassembly mat 10 to be wound on itself, as shown in Figure 4, so that it can be deployed quickly.

The stiffening elements 18 of the main portion of rolling, and the stiffening elements 24 of the rolling starter tab which extend in the transverse direction of the disengaging mat 10, give the mat a transverse rigidity without opposing to his winding on himself.

To guarantee the adhesion of the wheel RI on the belt 10, and in particular at the beginning of the exit phase of the rut, the rolling primer tab comprises a plurality of studs 28 which are arranged on the upper face 26 of the tongue.

In this example, the studs 28 are reported metal parts which protrude from the upper face 26 of the rolling start tab and which cooperate with the tire.

In this example, the hinge connecting portion 22 is also provided with crampons 28.

The main portion of rolling 12 and the rolling primer tab 20 are made of a textile covered with an elastomeric layer. It is the same for the hinge connection portion 22.

Such a material offers flexibility and excellent mechanical strength.

The stiffening elements 18 and 24 preferably extend in the thickness of the de-lidding mat.

Referring now to Figure 6, will be explained in more detail the operating mode of the disliner mat according to the invention.

The carpet is placed on the ground so that its main portion of rolling is disposed in front of the vehicle ahead of the rut O, while the rolling start tab is positioned at the bottom of the rut O being engaged under the forward drive wheel RI (not shown in Figure 7). The hinge connecting portion 22 makes it possible to lower the rolling start tab relative to the main driving portion. This makes it possible to incline and position all or part of the rolling start tab below the drive wheel before RI, as has been shown in FIG. 7.

As the main portion of rolling has a width substantially greater than that of the rolling start tab, and also thanks to the presence of transverse stiffening elements, the main portion of rolling remains substantially flat and does not collapse forming in turn a rut.

When the driving wheel before RI bogged starts to turn, the tire comes into contact with the crampons. The rotation of the wheel has the effect of pulling the start tab rolling under the wheel whereby the contact surface between the wheel and the rolling start tab increases.

As a result, more crampons engage with the tire, as a result of which the grip of the RI wheel on the rolling start tab increases. As the carpet is fixed to the ground, the wheel stops skating and rolls successively on the rolling start tab, the connecting portion and the main driving portion, following which the front wheel RI comes out of the rut O and can roll to the longitudinal end of the main driving portion opposite the tongue 20 without the risk of becoming bogged down.
