The solution of this task is carried out according to the invention with the features of claim 1 of the patent. Advantageous developments of the invention are described in the dependent claims.

A basic idea of the invention consists in constitute the surrounding transmission element from sliding bars and angular articulation elements arranged in a guide, in the form of links. This implies, as explained more go ahead with the help of an embodiment example, the advantage of that the transmission element can be adapted almost to any contour of a hatch cover or hatch closing. The activation device may be configured as activation lever for manual handling or as a motor electric gear for a motor activation, which can be also centrally controlled.

In an embodiment especially advantageous of the locking device according to the invention, as blocking elements used are arranged blocking rollers on the sliding bars and as against elements serve some hook-shaped closure plates arranged in the marginal zone of the hatch opening or in the loading opening, the which are configured and arranged in such a way that the locking rollers fit in the case of a displacement of the Transmission element in the closing plates. This is a way. of particularly simple realization in terms of construction, which also has the advantage that the part of the closing plate configured as a hook can have a surface inclined, on which the locking roller abuts during the blocking movement and in this way you can perform a shutter stroke, which drives the hatch cover or the closing hatch against the force of a gasket seal arranged in the cover or housing under the compression of the seal to the closed position, and thus the lid of hatch or the closing hatch is tightly closed Safely in front of the vehicle housing.

The following is explained in detail, with the help of the attached drawings, an exemplary embodiment for a locking device according to the invention.

In the drawings

Figure 1 shows the housing of a vehicle of Combat with closed trapdoor in an opening of load.

Figure 2 shows the vehicle housing according to figure 1 with the trapdoor open.

Figure 3 shows in enlarged representation in front of figures 1 and 2, a view on the loading opening in the closed state of the closing hatch with the parts of the locking device arranged in the closing hatch.

Figure 4 shows a section according to the line IV-IV in Figure 5.

Figure 5 shows in enlarged representation in front of figure 5 a section according to line V-V in figure 3.

Figures 1 and 2 show the housing of vehicle 1 of a combat vehicle not shown in detail with a cargo space 1.1 arranged in the rear area, whose opening Load 1.2 can be closed by means of a closing hatch 2. The closing hatch 2 is rotatable around an axis of rotation horizontal 2.1.

In the closed state of the closing hatch 2 shown in figure 1, it can be locked with the housing of the vehicle 1. The locking device explained in detail to then it can be activated by means of a lever rotary activation 5 arranged on the outer side of the trapdoor Closing 2, for locking and unlocking. The device of lock has a transmission element arranged so surrounding on the periphery of the closing hatch 2 in a guide 8, which is composed of sliding bars 6.1 to 6.6 and by 7.1 to 7.6 angular articulation elements arranged in the zones angle of the closing hatch 2. This transmission element can be moved in its longitudinal direction in guide 8. As it can be deduced from figure 3, the elements of Angular joint 7.1 to 7.6 are composed in each case by Guided links in slide guides 8.1 to 8.6. Through this configuration of the transmission element ensures that it can adapt to discretionary polygonal contours of a closing hatch or hatch cover. On the bars sliders 6.1 to 6.6 are arranged locking elements 3.1 to 3.8, which collaborate with opposing elements 4.a to 4.8, which are arranged in the car body 1 in the marginal area of the hatch opening 1.2. As can be deduced from the Figures 2 and 3, both locking elements 3.1 to 3.8 and also the opposite elements 4.1 to 4.8 are arranged distributed at different distances on the periphery of the cover of hatch 2 or loading opening 1.2.

Locking elements 3.1 to 3.8 are configured as locking rollers, which are fixed so swivel directly on sliding bars 6.1 to 6.6. The Opposite elements 4.1 to 4.8 are configured as plates of hook-shaped closure and are arranged in such so that the hook opening extends in each case in parallel to the direction of movement of the slide bar respective, so that in the case of a displacement of the sliding bar, the locking roller associated with it is guided inside the hook opening of the closure plate or is driven out of it. This can be deduced from the Figures 4 and 5, for example for the locking roller 3.1 and the plate Closing 4.1. In figure 4 the continuous lines are represented by locking position, in which the locking roller 3.1 fits into the hook-shaped opening of the closure plate 4.1. At unlocked state, the locking roller is represented with line of strokes and is designated with the reference number 3.1 '. Be located in front of the hook opening of the closing plate 4.1. The blocking stroke is designated with V. The closing bale 4.1 is fixed in an adjustable way through threaded joints 4.12 in the car body 1.

As can be deduced from Figure 4, the closing plate 4.1 has on the inner side of the part shaped as a hook an inclined surface 4.11, above the one that stops the locking roller 3.1 associated with it during the blocking movement. In this way, during the blocking, the closing hatch 2 is brought against the action of the force of a seal 11 represented in the Figure 5, with shutter effect to the closed position. The shutter stroke is designated with d in figure 4.

The coupling of the transmission element to the rotary activation lever 5 can be deduced from the Figure 3. To this end, the activation lever 5 is arranged a rotating 5.1 cogwheel during activation around the rotation shaft 5.2, which fits on a rack 9 fixed on the sliding bar 6.6. During the outward turn of the lever activation 5 to the unlocked position represented by line of strokes in figure 3, slide bar 6.6 and with it all the transmission element move in its longitudinal direction around a given path and in the case of backward turning of the activation lever 5 to the locked position, returns from New to the starting position. In this way a Manual locking and unlocking of locking elements 3.1 to 3.8 arranged in the closing hatch.

Obviously, instead of the device manual activation can also be provided a gear motor  electric, which is indicated in figure 3 with the number of reference 4 '. The output gearwheel of a gear motor of this type gears then on rack 9 on the bar slider 6.6 and causes the element to move transmission. A gear motor of this type can be activated also centrally from outside the vehicle.

For compensation of tolerances or game inside the guide 8 serves a tensioner 10 on the sliding bar 6.1.

The locking device represented and described serves in the exemplary embodiment for blocking a combat vehicle closing hatch, rotating around A horizontal axis of rotation. Obviously this device lock can also be used in a hatch cover rotating combat vehicles around a horizontal axis. From in the same way, the locking device can be used in closing hatches or hatch covers of combat vehicles, that can be rotated around an axis of vertical rotation or they can move in a horizontal direction and can then be lowered over the loading opening or hatch opening.
