slide to engage or disengage from the restraint and a lowered position, in which this movable structural unit is provided by a fixed element which forms a stop and is provided for this purpose is blocked. In the latter case, the bolt is consequently securely in its locking position held and there is no risk that he accidentally, for example, under the effect of bumps or vibrations disengages.

However, it happens that an operator by carelessness the operating handle of such a locking device folds down into the lowered position without having previously engaged the latch with the retainer. It also happens that a careless Operator leaves the operating handle in its raised position without the latch with the retaining device to have engaged. In either case, the movable wall is not in its raised position locked so that it can fall down or fold down by itself at the wrong time.

6 and 7 are sectional views along the line VI-VI from FIG. 4 and VII-VII from FIG. 5 and

FIG. 8 shows a representation corresponding to FIG. 2 of another embodiment of an inventive device Locking device.

Fig. 1 shows a pallet box 1, at least one of which Wall is formed by a plate 2 which is articulated at its lower edge by means of hinges 3 on the in this way form a horizontal pivot or tilt axis. This plate is arranged between two frame posts 4, which are connected to the other walls of the pallet box. Thus, this plate or wall can optionally can be folded out to facilitate access to the inside of the box, or it can be raised to form a corresponding wall of this box. At each of its upper corners is this plate with a Equipped locking device 5 according to the invention, as shown in detail in FIGS.

Each of these devices comprises a horizontal bolt 6 which slidably under guide and holding brackets 7, which are formed by a bracket made of metal wire, which is attached to the fold-up wall 2 is. This bolt is used to engage in a retaining bracket 9 made of metal wire, which is of the corresponding Frame post 4 is supported.

To operate the bolt, it is provided with a handle 10, which is formed by a metal wire bracket, des-

sen ends are soldered or welded to the transom. The assembly formed in this way can be a Axis, which is formed by the bolt 6, which consists of a piece of metal wire, which is rotatably mounted in the bracket 7 around its own axis.

The assembly formed in this way by the bolt 6 and the operating handle 10 is between one in the Fig. 2, 4 and 6 reproduced raised position and one in Figs. 3, 5 and 7 shown down folded Position can be swiveled back and forth. In the former of these two positions it is possible to release the bolt 6 to shift in one direction or another. So you have to bring the operating handle 10 into this position when the wall 2 is raised so that the latch 6 can be brought into engagement with the retainer 9. The handle 10 is then tilted downwards, which fixes or blocks the bolt in its locking position ensures. In fact, in this position, the one formed by the bolt 6 and the handle 10, Movable structural unit prevented from shifting in that one of the legs of the actuating handle 10 In the present case, the leg 10a between one of the retaining brackets 7 and an adjacent vertical strut 11 the movable wall 2 is included (see Figs. 3 and 5).

In this context it should also be pointed out that due to the arrangement according to the invention, the movable Assembly 6, 10 when folding the handle 10 down in the corresponding position simply due to of their own weight. In addition, when the handle is raised, this structural unit is not in a stable position and shows the

strive to tip down under the action of the slightest shock or shock.

According to the invention, the other leg 10b of the operating handle 10 comprises an extension 12 which extends over the bolt 6 extends out. This extension is bent, as can be clearly seen from FIGS. 2 and 4, in such a way that it forms a ramp which is capable of being attached to a fixed element of the flip-up wall 2 slide along when the handle 10 is folded down. This solid element forms another vertical strut 13 of the wall 2 opposite which the ramp 12 is when the handle 10 is in the raised position is located. In this context it should be noted that the vertical strut with the movable bolt 6 one includes right angle.

Under these conditions, when the operating handle 10 is folded down in the direction of arrow F1 is without the bolt 6 has previously been brought into engagement with the interior of the restraint bracket 9, the Ramp 12 brought to the fixed vertical strut 13 slide along. Due to the inclination of this ramp, this causes a displacement of the entire structural unit and thus also of the bolt 6 in the direction of arrow F2 until the bolt engages with the interior of the restraint bracket 9 occurs. Thus, the bolt is brought into its locking position in a defined manner when you press the operating handle 10 folds down or folds down.

In addition, this makes it unnecessary in the future to engage the bolt beforehand with the interior of the retaining clip 9 to bring, since this is automatically effected in that the operating handle 10 is folded down or folded over

will. Under these circumstances, the device according to the invention thus also has the distribution that one of the operating steps eliminates the previously necessary to lock a movable wall in its raised or in the folded-up position.

It should be noted, however, that this locking is also achieved when the operating handle 10 is left in its raised position by inattentiveness after the movable wall 2 is folded up became. In fact, due to the instability of the operating handle in this position, it has a tendency to undershoot to tip down at the effect of the slightest shock or shock. From this it follows sliding along the ramp 12 on the fixed vertical strut 13 and thus an automatic engagement of the bolt 6 with the retaining clip 9.

The locking device according to the invention thus leads to a much greater security than the previously used devices and has, as already mentioned has the advantage that the operation for performing the locking is simplified. This result however, is achieved without significantly complicating the structure of the locking device, i. e. so without any increase in manufacturing costs.

In the embodiment shown in Fig. 1, the locking device according to the invention is attached to a foldable wall 2, which is part of a pallet box forms. However, such devices can also be attached to the various movable walls of a pallet box be attached, which is completely collapsible. In such a case, all walls are hinged

Plates are formed and it is possible to use all or at least some of them with locking devices according to the invention equip.

The device according to the invention can be used in the same way can also be used with any other type of container that has a hinged wall or flap or any has a similar element, for example in a trolley equipped with a goods container, which has a fold-up wall or flap.

The invention also relates generally to containers of the type comprising a wall or other movable type Comprise an element equipped with locking devices of the type described above, so that the term "container" includes not only pallet boxes but also any other device that can be used to pick up or transport goods, i.e. e.g. also transport carts and the same.

In addition, it should be noted that the inventive Locking device is not limited to the embodiment just described. Thus, Fig. 8 shows a another embodiment in which the displacement of the Bolt when folding down the operating handle in its lowered position forcing ramp on the foldable Wall 2 itself is arranged in the form of a bent element 12a attached to this wall. In this case if the rectilinear element is in contact with this ramp when the handle is raised, from an extension 10b of one of the sides of the corresponding handle 10a.

Taking into account the reversal of the arrangement of these two elements is also the orientation of the ramp 12a

inversely to the orientation of the ramp in the previous case in order to automatically slide the bolt 6 into its To achieve locking position when folding the handle in its folded position.

Finally, it should be noted that in both cases the latch 6 and its operating handle 10 or 10a formed unit possibly also on the solid Frame post 4 can be attached instead of the fold-up wall 2, in which case the latter then the Restraint device or the restraint bracket 9 carries.

The invention thus creates a device that makes it possible to fold up a wall or the like in to lock its raised position in that a bolt carried by it in a retaining device intervenes. This bolt and its operating handle 10 can be pivoted about the axis that the bolt 6 itself is formed. The operating handle of the bolt has an element that forms a ramp 12 opposite a fixed element 13 is arranged on which it can slide when the operating handle in its lowered position is folded over or folded over. The shape of this ramp is chosen so that a The bolt 6 is moved into a position in which it engages the interior of the retaining bracket 9. If necessary, the ramp can be provided on the part that carries the bolt and its operating handle, wherein then the latter comprises a rectilinear element which serves to slide along this ramp when the handle is folded down. This device can be attached to flip-up walls or the like that are attached to any Containers, such as pallet boxes, transport containers of carts, etc. are attached.
