OPENING SUPPORT DEVICE FOR PORTAPALETS AND DRAWERS

METALLIC

OBJECT OF THE INVENTION

The purpose of this utility model is to present a new opening support device for pallet holders and metal drawers which has the utility of allowing the controlled opening and closing of the pallet lid / door of metal pallets or drawers and the maintenance thereof open

This new opening support device for pallet carriers and metal drawers has special application in the transport sector for use in pallet carriers and metal crates for trucks or other means of transport.

BACKGROUND OF THE INVENTION

To date there are different types of opening support devices for pallet holders and metal drawers that allow the lid or door to be held when it is open. This is the case of metal drawers or pallet holders that have a cable that connects the door with the box or pallet holder limiting its opening when its opening on the union hinge is towards the bottom of the pallet holder or metal drawer acting as stops or limiter of opening. These devices have the disadvantage that when opening the door / cover it is necessary to support the weight of the door so that it does not open abruptly due to gravity, being able to fall suddenly by breaking the cable or the hinge itself that joins the door / cover to the pallet holder or metal drawer

Also known are the opening devices that are used in the doors of the trunk of buses or trunk of cars that incorporate a pneumatic spring to slow down the opening and keeping them open.

There is no known metal drawer or pallet holder that includes an opening support device such as that described in the present invention.

This new opening support device for pallet carriers and metal drawers essentially consists of incorporating a pneumatic spring between the lid / door and the metal drawer or pallet holder.

With this pneumatic spring, the opening of the lid / door, when turning towards the top on the hinges that secure it to the drawer or pallet holder, is achieved in a controlled way without abruptness and that the lid / door is kept open due to the pressure exerted by the air spring.

The pneumatic spring is connected on the one hand to the lid / door by a connecting element that allows the rotation and on the other hand to another connecting element that also allows the rotation on the inner side of the drawer or pallet holder.

When opening the lid / door lock of the drawer or pallet holder, the force of the pneumatic spring pushes the lid / door and, when turning on the hinge that secures it to the drawer or pallet holder, opens in a controlled way to the point where the Pneumatic spring reaches its maximum length and keeps the lid / door open in this position.

The pneumatic spring is fixed to the drawer on one side of its interior and the drawer has a protective sheet that leaves a passenger compartment in which the pneumatic spring is housed when the lid / door is closed. It should be noted that this device is indicated for pallet carriers and metal drawers for trucks that move on the road with the movement of pallets or objects inside and with this protective plate prevents pallets or any object that is introduced into the box or pallet holder can hit the pneumatic spring directly, deteriorating it.

The present invention has as advantages the opening without abruptness of the lid / door while facilitating its opening due to the pressure exerted by the pneumatic spring and the maintenance of the lid / door open at the point of maximum expansion of the pneumatic spring as well as keeping the lid / door closed.

Descriptive report, as an integral part thereof, a series of figures in which, for illustrative and non-limiting purposes, the following has been represented:

- Figure 1: Global perspective view of the device with the pneumatic spring fixed to the drawer or pallet holder and its lid / door.

- Figure 2: View of the piece in detail of the connection of the pneumatic spring to the lid / door of the pallet holder or metal drawer.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the indicated figures, the opening support device for pallet carriers and metal drawers includes a pneumatic spring (3) that is fixed at one of its ends by means of a connecting element (2), which allows rotation , to the inner side of the metal drawer or pallet holder (1) and at the other end, by means of another connecting element (4), which also allows the rotation, to a piece (5) attached to the inner face of the lid / door (6).

This pneumatic spring (3) makes a pressure so that the lid / door (6) opens more easily by exerting pressure between this lid / door (6) and the drawer or pallet holder (1) by opening it to its maximum expansion point and keeping the lid / door (6) open in this position.

The opening support device for pallet carriers and metal drawers in accordance includes on the inner side face of the metal drawer or pallet holder a protective metal sheet (8) that delimits a vertical cabin intended for the accommodation of the pneumatic spring when it is compressed and the cover / door closed. When the lid / door (6) is closed, the pneumatic spring (3) is compressed and is housed and protected from possible shocks of the pallets or other objects that are in the drawer or pallet holder (1)

Likewise, the opening support device for pallet holders and drawers has a part (5) that fixes the pneumatic spring (3) to the lid / door (6) that is separated from the hinge fixing point (7) at a distance proportional to the maximum expansion length of the pneumatic spring (3). In this way, if the part (5) is placed far away from the hinge fixing point (7), and therefore from the pivot point thereof, the maximum expansion of the pneumatic spring (3) would not allow the complete opening of the

cover / door (6). Similarly, if the connecting piece (5) is placed very close to the pivot point of the hinges (7), the pressure of the pneumatic spring would excessively open the cover / door (6).

On the other hand, the part (5) that joins the pneumatic spring (3) to the cover / door (6) by a connection element (4) that allows the rotation, given the distance between the connection element (4) ) of the pneumatic spring and the plane of the lid / door (6), when the lid / door is closed, the expansion force exerted by the pneumatic spring (3) causes the lid / door (6) to remain closed by the arch of rotation that make the hinges. When the lid / door (6) is opened, due to the turning arc of the hinges, the pneumatic spring (3) is compressed

10 during a part of the path to then expand and keep the lid / door open and it is this initial compression of the pneumatic spring (3) that exerts a pressure to keep the lid / door closed. In the process of opening or closing the lid / door there is an initial compression and subsequent expansion of the pneumatic spring (3) which results in the lid / door (6) being kept open or closed by the pressure of the pneumatic spring (3 ).
