DETAILED DESCRIPTION OF THE INVENTION

[0029] FIG. 1 shows a stacking column S in which a plurality of pawls 5.1 to 5.6 are located between two side walls 1.1 and 1.2. Both side walls 1.1 and 1.2 are connected by a rear wall 2 (see FIG. 3) to form a U-body 3. This U-body 3 sits on a foot plate 4.

[0030] With regard to the arrangement of the pawls and their activity, reference is also made in particular to DE 20 2020 104 669 U1. In the present embodiment example, the lowest pawl 5.1 is also in the working position, while the next pawl 5.2 is in the ready position.

[0031] The lowest pawl 5.1 is operatively connected to the following pawls 5.2 and 5.3 via a linkage 6 (see FIG. 2), the latter being located in the resting position between the side walls 1.1 and 1.2. Reference is also made to the aforementioned DE 20 2020 104 669 U1 with regard to the design of the linkage 6.

[0032] Furthermore, clamping pawls 7 or hold-down devices are also shown, which press the load against the pawl 5.1-5.6 in the position of use and thus in particular counteract vibration during transportation. For example, such clamping pawls 7 are shown in DE 197 29 444 B4. However, they play no role in the present invention.

[0033] As also described in EP 3 231 740 A1, the pawls 5.1-5.6 are each connected to the opposing side walls 1.1, 1.2 via an axle bolt, whereby the pawls 5.1-5.6 rotate around the axle bolt. For the sake of clarity, the axle bolts are not shown here, but, as in EP 3 231 740 A1, they are located in the area of the transition from the rear wall 2 of the U-body 3 to the side walls 1.1 or 1.2, whereby the axle bolt is arranged between the two side walls 1.1, 1.2.

[0034] The stacking column S shown is used to store stored goods on top of each other or next to each other at mutual intervals on one of the pawls 5.1-5.6, which is rotatably mounted on the axle pin between two side cheeks 1.1, 1.2.

[0035] The axle bolt, which is not shown in detail, has an axle bolt spring that surrounds the axle bolt and rests against the rear wall 2 with one spring leg and rests against the pawl or the linkage bolt 9 with another spring leg. The axle bolt spring is used to pull the pawl 5.1-5.6 back from the working position into the ready position.

[0036] The side walls 1.1, 1.2 form a U-body 3 with the common rear wall 2, whereby the U-body 3 comprises the foot plate 4. In this context, encompassed means that the U-body 3 is joined to the foot plate 4, for example by welding.

[0037] The pawl 5.1-5.6 has a linkage bolt 9. The linkage bolt 9 is movably mounted within a curved slot 8 of the side wall 1.1, 1.2. As a result, the pawl 5.1-5.6 is mobilized in conjunction with the linkage 6 within the specification of the curved elongated hole and can thus in turn be pivoted from the resting position first into the ready position and then into the working position.

[0038] FIG. 2 also shows, for example, a linkage 6 that determines the position of the pawl 5.1-5.6 from a resting position via a ready position into a working position and back again, whereby the linkage 6 is operatively connected to the linkage bolt 9. The linkage 6 connects pawls 5.1-5.6 in a predetermined functionality and is sufficiently known from the prior art.

[0039] The linkage bolt 9 is extended through one of the side walls 1.1, 1.2, in this embodiment example through the side wall 1.2. As a result, when the pawls 5.1-5.6 are adjusted, which is accomplished by the interaction of the linkage 6 with the linkage bolt 9, the linkage bolt 9 is also simultaneously used to activate the locking mechanism by the locking link 14 of the individual pawls 5.1-5.6.

[0040] The linkage bolt 9 moves from the ready position into the working position along a bevel 11 of a locking link 14 and activates the locking link 14 from an initial position into a locking position.

[0041] The locking link 14 is arranged between the side wall 1.1, 1.2 or, in this example, between the side wall 1.2 and a slider 19.

[0042] In this design example, the slider 19 is a corner profile and is arranged at the transition from the side wall 1.2 to the rear wall 2.

[0043] The slider 19 is arranged to move along the side wall 1.2. However, the slider 19 comprises a slider spring in relation to the side wall 1.1, 1.2 or the rear wall 2, which is not shown in detail in the figures.

[0044] The slider 19 is arranged to move against the force of the slider spring, whereby the recess 15 brings the locking link 14 into an unlocking position via the spring fixation 12, i.e. unlocks it. This is achieved by the locking link 14 not being actuated by the linkage bolt 9 as in the locking process, but by the slider 19 being pushed away from the foot plate 4 and the recess 15 being entrained, whereby the recess 15 in turn entrains the spring fixation 12 and the locking link 14 performs an identical movement as in the locking process. Except that this time the coil spring 20 is not actuated, but instead the pivoting of the locking link 14 causes the axle bolt spring of the axle bolt of the pawl 5.1-5.6, which is not shown in detail, to pull the pawl 5.1-5.6 back out of the locked working position into the unlocked ready position.

[0045] The locking link 14 is connected to the side wall 1.1, 1.2 via an axis of rotation 13.

[0046] In addition to the axis of rotation 13, the locking link 14 also has a spring fixation 12, whereby a coil spring 20 is arranged between the spring fixation 12 and an anchor point 10.

[0047] The linkage bolt 9 is arranged in such a way that it slides along the bevel 11 up to a bolt receptacle 22, whereby the pawl 5.1-5.6 actuates the locking link 14 on its way from the ready position to the working position and the coil spring 20 absorbs a force, whereby when the pawl 5.1 reaches the working position (as shown, for example, in FIG. 1), the linkage bolt 9 slides into the bolt receptacle 22, whereby the coil spring 20 releases the previously absorbed force again. In FIG. 1, the pawl 5.1 is locked and the associated linkage bolt 9 is retracted into the bolt receptacle 22 so that the pawl 5.1 is locked.

[0048] At the same time, the pawl 5.2 is in the ready position and the associated linkage bolt 9 is again at the start of the associated bevel 11.

[0049] Furthermore, the locking link 14 forms a bolt receptacle 22 between the bevel 11 and the axis of rotation 13.

[0050] The spring fixation 12 is a rod element and projects away from the locking link 14 and through a recess 15 of the slider 19 away from the locking link 14 through the recess 15 of the slider 19, and the coil spring 20 is arranged between the anchor point 10 and the spring fixation 12.

[0051] The advantage of this design is that each of the pawls 5.1-5.6 has its own coil spring 20 for guiding and securing the locking mechanism, so that the force required for guiding the locking mechanism can be selected by selecting the force of the coil spring 20. Theoretically, it would even be possible to assign a different force-requiring coil spring 20 to each individual pawl 5.1-5.6.

[0052] FIG. 1 also shows that the foot plate 4 has an unlocking recess 23, with the slider 19 forming an unlocking tongue 24 above the unlocking recess 23. The background to this is that the pawls 5.1-5.6 are unlocked all at once by actuating the slider 19. For this purpose, there is an elevation or a pin or the like on a defined base, which engages through the unlocking recess 23 when the stacking column is set down and presses against the unlocking tongue 24 and thus pushes the slider 19 away from the base against the force of a slider spring on the U-body 3, which is not shown in detail.

[0053] The functionality of the lower pawl 5.1 to always return to the ready position as the starting position and not to be able to be returned to a resting position between the side walls 1.1, 1.2 is achieved by a stop that precisely prevents the lower pawl 5.1 from retracting between the two side cheeks 1.1, 1.2.

[0054] The mode of operation of the present invention is as follows and is explained in particular with reference to FIG. 4:

[0055] The initial position is shown in FIG. 4a, where the lower pawl 5.1 is in the ready position. Now, as shown in FIG. 4b, a load not shown in detail is placed on the pawl 5.1, whereby this pawl carries the clamping pawl 7 and the following pawl 5.2 via the linkage 6. The lowest pawl 5.1 reaches the working position, whereby the linkage bolt 9 runs along the bevel 11 on the locking link 14 and slides into an undercut bolt receptacle 22 in the end position. The locking link 14 rotates around the axis of rotation 13 and pulls the spring fixation 12 away from the foot plate 4. This pulls the bolt receptacle 22 over the linkage bolt 9. This locks the pawl 5.1.

[0056] When the next load is inserted between, for example, four similarly designed stacking columns S arranged in a rectangle, the following pawl 5.2 is now moved from the ready position to the working position via the linkage 6, as shown in FIG. 4c. The locking process is the same, so that the same reference symbols are used here. In this way, one pawl 5.1-5.6 after the other is loaded and locked. Locking each of the individual pawls 5.1 to 5.6 individually has the advantage that partial loading of the stacking column S is also possible without the unused pawls 5.1 to 5.6 also having to be pressed into the working position. In the case of partial loading, therefore, only those pawls 5.1 to 5.6 that are required are actually brought into the working position by the load.

[0057] To unlock all of the pawls 5.1 to 5.6, the slider 19 shown in FIG. 4d is used. It is lifted in direction x, which can be done in any way. For example, the stacking column could be placed on a plunger (not shown) after transportation with a load elsewhere in a factory hall, which penetrates an unlocking recess 23 in the foot plate 4 and hits the unlocking tongue 24 on the slider 19 so that the slider 19 can be guided upwards along guide pins. A lower edge of the recess 15 (see FIG. 2) meets the spring fixation 12, which protrudes from the locking link 14. This lower edge takes the spring fixation 12 with it and thus rotates the locking link 14 about the axis of rotation 13 so that the linkage bolt 9 can extend out of the bolt receptacle 22.

[0058] As soon as all stored goods have been removed, any fixing of the slide 19 is released so that it falls vertically downwards again and the locking links 14 return to their initial position, as shown in FIG. 1, via the coil springs 20.
