Description

DESCRIPTION

Locking mechanism for vehicle bodies

TECHNICAL SECTOR

The present invention refers to an automatic closing mechanism for vehicle bodies, specifically truck or container boxes, of the type in which its upper area can be closed by means of a practicable mechanism, such as a tarpaulin or the like, and in which in correspondence with the rear access doors of the container or box there is a separating bar as an upper frame for the same, and which is capable of being folded down to facilitate access to the interior of the box.

The object of the invention is to provide a mechanism that allows a quick and safe unlocking of said spreader bar, from the lower area of the bodywork, avoiding risks of falls, and saving execution times.

BACKGROUND OF THE INVENTION

In the scope of practical application of the invention, certain boxes of trucks or containers that are capable of being opened both at the rear and at the top to facilitate access to the goods contained within, present in correspondence with the rear area in which the rules are established. access doors to the same, an upper frame or separator bar, which is horizontally foldable through hinge means established on one of the sides of the body, with a locking mechanism on the opposite side, of the same type of used in the doors and gates of automobiles, in which there is a mouthpiece that faces a housing seat for the locking element, a seat that is angularly movable and lockable with respect to the mouthpiece by the pressing of the locking element itself. locking on it, so that said seat is unlockable by actuation of a trigger.

Thus, this type of bodywork allows one, both doors to be opened, as well as if it were necessary to fold down the upper frame or spreader bar, to further facilitate access to the contents of the box, as it is superiorly practicable.

However, to date, the usual thing to do to lower the spreader bar is to have to climb with a ladder to the height of said bar and manually release the bar lock by actuating the aforementioned stem.

This supposes a wide and varied problem, among which the following aspects should be highlighted:

• Discomfort: The driver has to climb onto the body with a ladder, which is an uncomfortable maneuver.

• Insecurity: The fact of having to climb a ladder to a certain height poses a risk of falling. So much so, that in certain companies they are not allowed to carry out this action within their facilities to avoid taking risks, and they must go out only to open this bar.

• Loss of time: The time to take the ladder, climb onto the bodywork, place the ladder, climb on it, open the lock, go back down, etc., is a significant waste of time.

EXPLANATION OF THE INVENTION

The automatic closing mechanism for vehicle bodies that is advocated fully satisfactorily solves the problems previously exposed in the different aspects discussed, based on a simple but effective solution.

To do this, and starting from the conventional locking mechanism described above, it has been foreseen that it is established hidden within the body of the box itself, in the upper area of the side edges of said body and in correspondence with the hinge area of the box. one of the doors, revealing an opening that It will correspond to the tilting seat of the locking mechanism and which is intended to receive the locking rod in which the corresponding spreader bar is finished, which is foldable through hinge means associated with its opposite end, including this bar in its area media, the usual means of reception and blocking of the classic vertical bars that participate in the closing mechanism of the doors of this type of boxes or containers.

Well, in accordance with the essence of the invention, provision has been made for the release trigger of the locking mechanism of the spreader bar to be linked with a cable, wire or metal rod that extends through the interior of the bodywork and through a channeling to the lower area of said bodywork, in which said cable, wire rope or rod will be associated with an actuation mechanism and vertical displacement thereof, either by means of a pull, push-button, lever or conventional manual mechanical system or a through an electric / pneumatic / hydraulic actuator whose drive control will be accessible in said lower body area.

In this way, by simply pressing a button, lever or control, fully accessible to the driver from the ground, without having to use ladders or extension accessories, it is possible to release the spreader bar to improve accessibility conditions inside the box or container , in a minimum time, in a comfortable and safe way.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1.- Shows a perspective view of a container or vehicle box that incorporates an automatic closing mechanism made in accordance with the object of the present invention.

Figure 2.- Shows a detail in perspective of the mechanism at the level of the locking means for the spreader bar, a bar that does not appear coupled to said mechanism.

Figure 3.- Shows a profile view of the assembly of the previous figure.

Figure 4.- Shows, finally, a lateral and perspective detail of the body of the box at the level of the mechanism of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the mechanism of the invention is intended to be implanted in boxes (1) or vehicle containers of the type constituted from a rectangular prismatic body, which have its upper area (2) open and practicable by means of canvases that can be extended over a series of transverse crossbars (3), finishing the box or container in its rear area with a pair of doors (4) that include a closing mechanism (5) that links the doors to a separator bar (6) as an upper frame of the doors, as well as an intermediate and lower zone (7) of the bodywork, incorporating the separator bar (6) hinge means (8) on the horizontal plane, for which the end opposite its hinge means is finished off in a rod that is capable of being immobilized in a locking mechanism (9) of the type used in the locking of doors and gates of automobiles, in which An opening (10) is defined that coincides with a tilting seat associated with a locking mechanism whose pressing causes said seat to rotate and lock around the locking rod of the spreader bar (6), preventing it from leaving the opening (10).

Well, as is conventional, this type of mechanism has a release trigger (11) which, given the installation area (15) of the mechanism, is hardly accessible.

For this, it has been foreseen that said release trigger (11) is linked with a cable, wire or rod (12), which runs vertically downwards through the interior of the body through a chamber (14), until it reaches the lower area (16) of said bodywork, in which said cable, wire rope or rod will be associated with a drive mechanism (13) by means of which said cable, rod or wire rope is moved vertically in a downward and upward direction, either by means of a handle, push-button, lever or conventional manual mechanical system or by means of an electric / pneumatic / hydraulic actuator whose drive control (14 ) will be accessible in said lower body area.
