must be avoided on objects that may be in the path of movement of the mobile container can. In the case of static stacking, the known stacking or stacking systems are sufficient. Support devices the given Requirements that are limited to, that a flawless mutual positioning of the stacked containers is ensured.

If, on the other hand, you want to move a unit formed from at least two stacked containers, either by Pulling can be done if these containers are mobile, or can be done with the help of a forklift truck, if the containers stand on feet, the stacks or Support devices hold the unit together make sure that is sufficient to avoid any danger of a

Tipping and falling of the upper container or containers to avoid.

The invention is thus based on the object f is a forward, direction for locking and for retaining the upper

b container in its stacked position to create the

a transport or loading of a unit consisting of at least two stacked containers in absolute terms allows safe manner and eliminates any risk of tipping of the upper container or containers during transport.

To this end, according to the invention comprises the device for stacking a transport container on a corresponding one Container has at least two locking devices for locking the stacked or upper container the lower container, which are arranged at opposite corners of the container and each of which a foot attached to the bottom of the container, the

has at its lower end a bracket which has an anchoring element can enclose that forms part of the lower container, as well as a locking element, which is articulated in a pivotable manner on the foot so that the bracket of the latter automatically with the one enclosed by it Anchoring element of the lower container is locked when the upper container is on the lower one Container is stacked or deposited.

According to a preferred embodiment of the invention the foot has the shape of a vertical U, while the bracket has the shape of a substantially horizontal U and is attached to the base of the foot in such a way that the anchoring element of the lower container into the interior of the bracket or can enter into the cavity enclosed by the bracket, the locking element around a horizontal, transverse axis attached to the foot is rotatably or pivotably attached and has an end hook, which is suitable to come into engagement with said anchoring element and on this the upper one or to lock stacked container in that the locking element tilts freely about its axis.

Thus, when a container or trolley that is equipped with at least two devices of the type mentioned is equipped, which is arranged diagonally at two opposite corners of the base of this container are, is stacked on a corresponding container, the bracket the associated anchoring elements, while the locking element tilts around its axis with its hook so that it is in the anchoring element inside the bracket engages, whereby by means of this locking hook, the upper container is fixed to the lower one

- 4 tanks are connected.

According to a preferred embodiment, the locking element comprises above the end hook a bent or curved lever, which with its lower part with a transverse sleeve or socket is connected, which is attached or mounted so that they are around the can rotate fixed axis of the foot, as well as a tilting element connected to the socket, which at its lower end the Bears locking hook, the curved or bent lever is perpendicular to the axis of rotation and has a length which is so great that the entire locking element is automatic due to gravity or automatically tilts about this axis into the locking position in which the hook enters the interior of the Anchoring element engages and comes to rest on the bracket.

It is understood that under these circumstances the locking element for carrying out the stacking or placing process must be held in an unlocked position in which the hook is folded away with respect to the anchoring element is countersunk to allow the bracket to engage around the anchoring element. As soon as the top If the container sits on the support devices of the lower container, the locking elements are allowed to fall back, which then only tilt due to gravity until the corresponding hooks are in their locking position reach.

In this way, the upper attached container is firmly anchored to the lower container so that the two Containers existing unit can be transported absolutely safely, which can either be done that one it pulls when it comes to trolleys or mobile containers

Figure 5 is a partial perspective view of two stacked containers with the upper container having a locking device 1 to 4 possesses.

In Fig. 1, a lower container 1 is shown, above which a corresponding container 2 is arranged, the to be placed on the container 1 and in its position by two forks 3 of a forklift, not shown is held. In the example shown, the containers 1 and 2 are mobile containers or baskets equipped with wheels 4 shown in Fig. 5 and for transport or storage of various items in warehouses or stores. In a known manner, these mobile containers or baskets formed by metal wire grids, for example from the vertical wires 5, on which horizontal Wires 6 are soldered or welded to form the walls and bottom of a container in the form of a right-angled Form parallelepipets 1,2.

Each of the containers 1, 2 has a device which is used to stack it on a corresponding container or put on and in the embodiment 4 shown in the figures locking devices 7 on the includes containers placed on the lower container, each at a corner of the base or the bottom of the container 1.2 are appropriate.

Each locking device 7 is constructed in the following way:

It initially comprises a foot 8 which is firmly connected to the bottom 9 of the container 1, 2 and at its lower one End carries a bracket 11 which is suitable for an anchoring

element 12 to enclose part of the lower The container forms, as well as a locking element 13 which is articulated on the foot 8 so that the anchoring element 12 enclosing bracket 11 in the servicing position automatically or is automatically locked when the upper container 2 is placed on the lower container 1.

In the illustrated embodiment, the foot 8 has essentially the shape of a vertical U, the upper ends 8a bent in the horizontal direction and on two transverse metal wires 14 of the bottom 9 through Soldering or welding are attached (Fig. 3).

The bracket 11 has the shape of a substantially horizontal one U, with its two legs arranged between the legs of the foot 8 at its base or lower end are; the attachment of the bracket 11 to the foot 8 is / the one shown Example carried out by soldering or welding and the bracket 11 is arranged so that it with respect to the Foot 8 protrudes laterally to the outside of the latter in order to allow the anchoring element 12 to be inserted into the interior of the bracket to allow.

The anchoring element 12 is formed by a pin or rod in the shape of an inverted U, the legs of which are firmly connected to an upper, horizontally extending wire 15 of the lower container 1. Furthermore the rod 12 is assigned to a support device 16 which is attached to the same container 1 and over the uppermost horizontal wire 15 of this container also in the way protrudes so that it can serve as a support for the corresponding bracket 11 of the upper container.

The locking element 13 is attached so that it is around a horizontally extending axis 17 rotated or pivoted

which runs transversely at foot 8 about halfway }

Device / locked, which happens that the locking element 13 tilts freely about axis 17.

Furthermore, the locking element 13 comprises a bent lever above the upwardly bent end hook 18 or angle lever 19, which is characterized by a short / ^ Da and a longer leg 19b is formed, the one between them include a given angle; the short leg 19a is at its lower part with a transverse sleeve or Bushing 21 connected, which is mounted so that it can rotate about axis 17. The socket or sleeve 21 is in turn firmly connected to a tilting element 22, which is closed at its lower end by the locking hook 18 is and is offset on the sleeve 21 in the horizontal direction with respect to the angle lever 19, as shown in FIG removes. The lever 19 is perpendicular to the axis of rotation 17 and its longer leg 19b, which is to Inside of the container 1,2 extends towards, has a length which is large enough to dip by gravity

automatically said locking element 13 / around the axis 17 to tilt into its locking position, in which the hook 18 engages under the horizontal web of the anchoring rod or anchoring bracket 12 and on the bracket 11 comes to the plant (Fig. 4 and 5).

The longer leg 19b forms with the short leg 19a an angle less than 90 °, which is Festgelec in such a way that the lifting of the long leg 19b out of his

Locked position essentially up to the level of the base 9 of the corresponding container (arrow F in Fig. 4) the tilting element 22 and its hook 18 can pivot to / a position in which it is inside the foot 8 is hidden or sunk, as shown in Fig. 4 with dashed lines and identified by the reference numerals 22a and 18a. One can see that the locking hook 18a disengaged in this position has stepped with the anchoring part 12, so that the stacked container 2 from the lower container 1 can be separated after the tilting element has been pivoted about the axis 17 through an angle which corresponds to the angular amplitude by which the longer arm 19b has been raised.

In the embodiment described, the foot is a U-shaped bent flat iron, the legs of which are light are spread apart, but this foot could also be designed in some other appropriate way be.

Preferably, the bent lever 19 is between two transverse wires 14 of the bottom 9 arranged so that these wires its tilting movement starting from the

the

one or / other of its two positions do not interfere, the bent part 19c of the lever 19 itself can extend substantially up to the level of the wires 14 (Figure 3).

In the example shown in the figures, each of the containers 1 and 2 has four locking devices at its base 7, which are each arranged at one of the corners, and in its upper part 4 corresponding

Counterparts, which are each formed by an anchoring rod 12 and a stop 16 and serve to one to pick up the attached container.

The formed by these four locking devices 7 and the associated support and anchoring elements 12, 16 Stacking device is used in the following ways:

When the lower container 1 rests on the floor, there are the four locking elements 13 that belong to it Stacking device belong, in the lowered locking position (Fig. 1 and 2), because due to gravity the weight of the respective longer arm 19b the hooks holds the bracket 11 in its locked position in contact,

as explained above.

In order to place a container 2 on the container 1, the forks 3 of a forklift truck are inserted under the base 9 and moves the container 2 into the position shown in Fig. 1 above the container 1, so that the four brackets are accurate are positioned over the associated anchoring rods 12 of the lower container 1. The forks 3 are under the four levers 19 arranged so that the long

, Legs 19b are in their raised position (like

it is shown in FIGS. 1, 2 and 4 in dashed lines), and that the four hooks 18 are correspondingly between the legs of the feet 8 are withdrawn, which makes it possible for the four brackets 11 to encompass the four rods 12 and

to come into contact with the support devices 16.

When the forks 3 are lowered (FIG. 2), the locking elements tilt 13 about their axes 17 under the action of the weight of the long leg 19b and come into the

2 to 5 shown position in which the hooks 18 under the horizontal webs of the locking elements 12 engage and rest against the transverse webs of the bracket 11 after the lifting ?. 19 and the tilting elements 22 their pivoting movement about the axes 17 is carried out to have.

The upper, placed on the lower container 1 container 2 is thus by its four locking elements 13, the cooperate with the four corresponding anchoring parts 12 of the container 1, firmly on the lower container anchored. This eliminates any risk of the upper container 2 tipping over during transport the two containers existing unit avoided.

The invention is not restricted to the embodiment described and comprises a number of variant embodiments. For example, the containers cannot be taken from the be mobile type and therefore only rest on feet 8. The number of locking devices 7 in the stacked position can be reduced to two, which are then diagonally opposed to each other Corners of the base 9 are attached. Likewise, the feet 8 on metal wires of the base 9 or on any otherwise to the base of the container by any suitable means such as screws, rivets or by welding, - the latter corresponding to the illustrated embodiment. The bracket 11 can on the feet 8 by any other type of fastening than by welding, for example with the aid of Screws or rivets.
