FR2617786A1 - Handling trolley - Google Patents

Abstract

The present invention describes a lightweight and foldable handling trolley which allows any individual to load or unload heavy objects without effort and therefore without risk of injury. This trolley is characterised by the fact that it has a support spoiler designed so that it is possible to make the whole trolley pivot about the said spoiler this being so as to bring the platform which supports the load into contact with the surface which is to receive or from which it is suitable to take up the objects. The invention is of interest to the field of goods-handling in general; it will find a particularly advantageous application for loading or unloading boots of motor vehicles.

Description

TRUCK
The present invention relates to the field of handling in general and more particularly that of the loading or unloading of objects above and beyond an obstacle.

Each individual, man or woman, is called, in his life, to handle more or less heavy loads which it is advisable to seize behind an obstacle, to bring above the said obstacle and to deposit in front of the same obstacle it is all also frequent to carry out these manipulations in reverse order, that is to say to grasp a load, bring it over an obstacle and finally place it behind this obstacle. If we take for example the case of loading or unloading a vehicle trunk, it is well known, in fact, that the handling of heavy loads, a bag of cement for example, is, depending on the individual, more or less easy, even impossible and that it is, in all cases and taking into account the gestures, efforts and positions that it requires strongly advised against by the medical profession (risk of lumbar accidents).

The present invention solves these problems; it offers a handling trolley which offers everyone the possibility of carrying out, without effort and therefore without risk, the loading or unloading of a vehicle trunk and more generally the loading or unloading of objects above or beyond of an obstacle.

The present invention describes a handling trolley intended to grab and / or deposit loads on a surface, above and beyond an obstacle, trolley comprising
- a support plate provided with a stop
- a base fitted with a support spoiler and
wheels characterized by the fact that in the transport position, that is to say when said wheels are in contact with the ground, said stop is located directly above the base, set back from the spoiler support so that it is possible, by rotation of the entire carriage around said support spoiler, to bring said stopper into contact with said surface which is to receive or from which it is appropriate to grasp said charges.

The invention will be better understood on reading the description below.

Figure 1 shows a general view of the carriage according to the invention.

Figure 2 shows the carriage in the transport position.

Figures 3, 4 and 5 show the various positions of the carriage in use.

Figure 6 shows schematically the entry or deposit of a load in a vehicle trunk.

Figure 7 shows schematically the seizure or the deposit of a load on the ground.

Referring to FIGS. 1 and 2, it can be seen that the trolley object of the invention essentially comprises a support plate (1) intended to apprehend a load (6) provided on one side with a stop or shovel (2), foldable around an axis (10) and on the other with angled handles (7) intended on the one hand to manipulate the carriage and on the other to maintain it in a stable position, when stationary, by contact on the floor (8).

The support plate (1) is articulated around an axis (9) located above a base (3) itself provided, on the front, with a support spoiler (4) and, at its base, wheels (5); the wheels (5) will be mounted on an axis (11) itself connected to the base (3) via the junctions (12) and (13).

We will now describe the carriage in the transport position, that is to say, from the stop position as shown in Figure 1, simply grasp the device by the handles (7) to advance the 'together ; arrived near the car trunk (14), it should (Figures 3, 4, 5 and 6)
- raise the handles (7) until the spoiler (4) comes into contact with the ground (8) (figure3)
- to balance the support plate (1) by rotation around the axis (9) while continuing to push the carriage towards the trunk (14) this in order to rotate the entire carriage around the spoiler (4) ( Figure 4); the wheels (5) then leave the ground
- to continue the rotation movement previously initiated (Figure 5)
- Bring the stop (.2) into contact with the bottom of the trunk (14) (Figure 6).

When it comes, more generally, to deposit a load behind an obstacle, the rotation movement already described, can be continued until the stop (2) comes into contact with the ground (8) (Figure 7 ).

In the context of unloading a vehicle trunk or entering a load on the ground, it suffices to reverse the operations, that is to say that FIGS. 6 or 7 represent the initial situation, the sequence of operations then being represented, in order, by FIGS. 5, then 4, then 3, then 2.

In a preferred embodiment according to the invention, the carriage will be such that
- the entire device is made up of aluminum tubes and profiles in order to make it light on the one hand and to allow on the other hand to design it foldable (articulated junctions (12) and (13))
- The handles (7) slide in the profiles (15) of the support plate (1); this allows, depending on the loads to be transported, to adjust the lever arm.

 - The rotation of the support plate (1) around the axis (9) is limited by a stop (16); this allows, in particular, to maintain, at rest, the plate (1) in a stable position.

 It goes without saying that the applications indicated here by way of example are not limiting. Various modifications can therefore be made by those skilled in the art to the embodiments described and shown, without departing from the spirit of the invention. ~
