Description

Leveling anti-theft ramp.

Object of the invention

The present invention aims at a ramp  anti-theft leveling

Field of the Invention

The invention is applicable in the springs of loading and unloading trucks of all kinds, facilitating the passage of the load of the ship corresponding to the body of the vehicle, bridging

Background of the invention

The applicant is the owner of the Spanish patent  No. P 9200815 which refers to a tilting ramp of this type comprising a platform constituting the tilting ramp in whose leading edge is articulated a lip or eave, and whose platform is articulated by the rear edge to a bench, which It is placed in a housing provided on the dock. The ramp with the Bench forms a unique set.

The applicant also holds the Spanish patent No. P 200400125 relating to a leveling ramp of this type, in which the platform constituting the ramp incorporates an articulated lip or eave at the front edge, which is supported by a bench, to the that the ramp is articulated by the rear edge. The ramp is oscillating by hydraulic means that at the same time make the lip oscillate with respect to the ramp. The assembly is transportable in several units in stacked form, and they are installed in a concrete pit in which a pre-frame is anchored
metal.

The two types of ramps cited by the applicant itself, and many other types of ramps applicable to loading / unloading docks of trucks, existing in the market, act as such tilting, leveling and provided branches of an eave or previous lip that makes "bridge" between the ramp mounted on the dock and the rear of the body of the vehicle in question, all this being the dock, and therefore, the door of the same at a certain height from the normal ground. In said resting position the eave or lip is directed vertically and inferiorly leaving the
ramp.

The current picaresque in terms of robberies has arrived  to an unimaginable point for a short time. Thus, there are individuals who place a vehicle, for example, type car or similar, inside the body or drag platform of a truck (trailer), preferably positioned with the part front (engine) directed towards the back of the body, that is, facing the dock door. This way, they attach the body to the dock, that is, to the ramp with the eave or lip directed inferiorly, in normal position of upload / download After which, they start the car or similar, at great revolutions so that it has great power, they pass by the ramp, they break the dock door that allows access to the corresponding industrial building, steal the content interior of the ship arranging it in the body of the trailer, and They run away.

To prevent such thefts, there is some manufacturer that in the resting position (horizontal) of the ramp keeps the eave, lip or nail in an upright position, to avoid Passage of a vehicle along the large ramp. acceleration and power from a truck attached to the dock for loading and unloading.

There is a manufacturer that manufactures these ramps Anti-theft that present some inconveniences. So, you can cite, among others, that the nail or lip of the ramp presents longitudinal (elongated) collision holes to the ramp, and this It implies a remarkable cost of machining and assembly. Also when the ramp is in the open position (that is, the ramp and the nail essentially in a horizontal plane) the nail protrudes totally cantilever of the ramp, which causes a moment or large pair, which forces an oversized mechanism, and all This makes the ramp as a whole more expensive.

The aforementioned drawbacks have been totally eliminated by the leveling anti-theft ramp object of the present invention

The lip, eave or nail is directly operated by a cylinder that holds the ramp at rest in closed position, that is, perpendicular to the position essentially horizontal of the ramp.

Therefore, the ramp of the invention does not require have a socket or stop to prevent the fall or slip wheelbarrows and others located above the ramp.

The lip of the ramp acts as an anti-theft because stops, being in an essentially vertical position with respect to to the ramp and to the ground. Which prevents any vehicle from leaving flying from the body of a truck or similar and go through the ramp to break the corresponding access door.

Summary of the invention

According to the above, the leveling ramp anti-theft object of the present invention, applicable to springs of loading and unloading of trucks, which includes the constituent plate of the ramp, the articulated lip on the leading edge of the ramp, and the support bench that fits into a dock housing, whose ramp is articulated by its posterior edge to the bench of support and scale in elevation and descent through the horizontal by means of actuation that swing the lip at the same time front between the same ramp plane and an orthogonal plane to the same, and is characterized essentially because the articulated lip It consists of a continuous plate that in the rest position adopts an essentially vertical active anti-theft position, whose position is orthogonal with respect to the horizontal position of resting the ramp, far exceeding the upper edge of the quoted lip, the level of the loading dock.

According to the invention, the articulated lip in the leading edge of the ramp is tilted by means of independent drive of the drive means of the ramp.

The set comprising the support bench,  the ramp, lip and drive means form a unit transportable.

The ramp and lip drive means consist of respective hydraulic cylinders and / or
tires

These and other features will come off better than the detailed description that follows, to facilitate which two sheets of drawings are accompanied in which it has been represented a case study that is cited only by way of non-limiting example of the scope of the present invention.
