Description

[0001] The invention relates to a picking trolley according to the preamble of claim 1.

[0002] From DE 93 00 111 U1, a picking trolley is known which comprises a frame, at least one wall, at least one joint associated with the wall, and rollers, wherein the joint is formed by two opposing joint means and wherein the wall is pivotally connected to the frame via the joint means about a pivot axis oriented horizontally in space. In a first position, the wall acts as a side panel, preventing access to and viewing of a receiving area of ​​the picking trolley, and in a second position, the wall forms a shelf of the picking trolley.

[0003] The invention is based on the objective of proposing a picking trolley in which at least one wall can be moved between a working position and a rest position without impairing the usability of the picking trolley in the rest position.

[0004] This problem is solved by means of the characterizing features of claim 1, starting from the features of the preamble of claim 1. Advantageous and expedient embodiments are specified in the dependent claims.

[0005] The order picking cart according to the invention comprises an intermediate shelf held on the frame, a linear guide by means of which the wall is guided so as to be horizontally displaceable, and a locking mechanism with which the wall can be fixed to the frame in a working position such that the wall forms a fixed side wall of the order picking cart. To move the wall from the working position to a rest position, it can first be detached from the locking mechanism, then, guided by the pivot points, pivoted away from the frame about the pivot axis into a horizontal position, and finally, guided by the linear guide, slid under the intermediate shelf. In such an order picking cart, the wall is supported under the intermediate shelf in the rest position in such a way that it does not impair the usability of the order picking cart in any way. In its working position, the wall fully assumes the function of a side wall.In this way, the invention optionally enables the picking trolley to be equipped with a wall serving as a side wall, without any disadvantage arising in the use of the picking trolley from not using this option.

[0006] Furthermore, it is provided that the wall, in every intermediate position it can assume between the working position and the resting position, is connected to and guided by the joints. This ensures that the wall is permanently attached to the frame of the order picking cart.

[0007] It is also intended that the wall, in its working position, be aligned with the intermediate floor in such a way that at least 50% of its height, measured in the working position, projects above a surface of the intermediate floor. This makes it possible to effectively secure material stored on the intermediate floor against falling. If the wall also projects downwards beyond the intermediate floor, it is simultaneously possible to use the wall to laterally secure material stored below the intermediate floor.

[0008] It is also planned to position the closure above the intermediate floor on the frame. Such an arrangement allows for intuitive operation of the wall.

[0009] Furthermore, it is provided that the linear guide comprises a first linear guide element and a second linear guide element, and that the closure comprises a first closure element and a second closure element. This allows the linear guide and the closure to be designed as technically simple components by positioning them laterally against the wall.

[0010] Accordingly, it is provided that the first linear guide comprises a guide rail connected to the frame, that the second linear guide comprises a guide rail connected to the frame, that the first locking means comprises a bolt connected to the frame, that the second locking means comprises a bolt connected to the frame, that the first joint comprises a bolt connected to the frame, and that the second joint comprises a bolt connected to the frame, wherein the axes of the bolts forming the locking mechanism lie on a first straight line and the axes of the bolts forming the joint lie on a second straight line. This design makes it possible to arrange the linear guides, locking mechanisms, and joints directly on the frame of the order picking cart, so that no adapters are required for their installation.

[0011] Furthermore, it is planned that a first assembly unit comprises the first linear guide and the first coupling element, and that a second assembly unit comprises the second linear guide and the second coupling element. Combining the linear guide and coupling elements into a single assembly unit reduces assembly effort.

[0012] Regarding the design of the wall, it is provided that the wall has at least one opening on its transverse sides in the region of its upper longitudinal side, which is designed such that the first or second locking element of the closure can enter or exit an undercut in the wall when the wall pivots about its pivot axis, and that the wall includes an undercut on its underside in which the first and second hinge elements are received in such a way that the wall is captive and held to the frame. A wall designed in this way is easy to manufacture, in particular as a one-piece sheet metal or plastic component.Furthermore, such a design makes the order picking trolley insensitive to displacements of the individual components that occur under extreme dynamic loads, since the wall is positively connected to the locking means in its working position due to its design.

[0013] It is also planned to construct the frame of the order picking cart from metal profiles, and in particular from lightweight metal profiles, with these profiles being designed primarily as hollow profiles. This allows the weight to be kept low while maintaining high stability, thus facilitating the handling of the order picking cart and making it insensitive to dynamic loads.

[0014] Finally, the intermediate shelves and / or walls are designed as folded metal profiles, folded light metal profiles, or sandwich panels. This allows the weight to be kept low while maintaining high stability, thus facilitating the handling of the order picking cart and making it resistant to dynamic loads.

[0015] Further details of the invention are described in the drawing with reference to schematically illustrated embodiments.

[0016] This shows: Fig. 1: a perspective view of a picking trolley according to the invention and Fig. 2, Fig. 3, Fig. 4 to Fig. 5: Perspective views of the picking trolley, with the wall in different positions in each view.

[0017] In the Fig. Figure 1 shows a perspective view of a picking trolley 1 according to the invention. The picking trolley 201 also includes schematically indicated casters LR.

[0018] The order picking cart 1 comprises a frame 2, which includes two frames 3 and 4. Furthermore, the order picking cart 1 includes four intermediate shelves 5, 6, 7, and 8, which are arranged at different heights between the two frames 3 and 4 and connect them. The order picking cart 1 also includes four walls 9, 10, 11, and 12, which are assigned to the intermediate shelves 5, 6, 7, and 8. Finally, the order picking cart 1 includes four joints 13, 14, 15, and 16, linear guides 17, 18, 19, and 20, and closures 21, 22, 23, and 24, each assigned to the intermediate shelves 5, 6, 7, and 8, and to the walls 9, 10, and 12, respectively.

[0019] In this case, each joint 13, 14, 15, 16 comprises two opposing joint means 13a, 13b or 14a, 14b or 15a, 15b or 16a, 16b, each of which is designed as a bolt.

[0020] In this case, each linear guide 17, 18, 19, 20 comprises two linear guide means 17a, 17b or 18a, 18b or 19a, 19b or 20a, 20b, each of which is designed as a guide rail.

[0021] In this case, each closure 21, 22, 23, 24 comprises two opposing closure means 21a, 21b or 22, 22b or 23a, 23b or 24a, 24b, each of which is designed as a bolt.

[0022] The walls 9, 10, 11, 12 are connected to the framework 2 via the joint means 13a, 13b or 14a, 14b or 15a, 15b or 16a, 16b in a pivot-joint manner about pivot axes S13 or S14 or S15 or S16, respectively, which are oriented horizontally in space.

[0023] The walls 9, 10, 11, 12 are guided horizontally displaceably in the linear guide means 17a, 17b or 18a, 18b or 19a, 19b or 20a, 20b respectively below the intermediate floors 5, 6, 7, 8.

[0024] Walls 9, 10, 11, 12 are in the Fig. 1 is shown in various positions. The wall 9 is in a working position A9, in which the wall 9 is fixed to the frame 2 such that it forms a fixed side wall SW of the picking cart 1 and, with respect to its height H9 measured in a vertical orientation, projects at least 50% of this height H9 beyond a top surface 5a of the intermediate floor 5. The wall 12 is approximately in a rest position R12, in which it is completely inserted under the intermediate floor 8.

[0025] In the Fig. 2, Fig. 3, Fig. 4 to Fig. Figure 5 now shows in detail how the wall 9 is removed from its previously described working position A9 (see Figure 5). Fig. 2) into a rest position R9 (see Fig. 5) is spent.

[0026] The wall 9 is constructed identically to the other walls 10, 11, 12 and is formed by a plate 25 which is folded over twice by 90° on opposite longitudinal sides 9a, 9b, so that a web 25a or 25c with a nose 25b, 25d is obtained (see in particular Fig. 4 and Fig. 5) An undercut 26, 27 is formed on both longitudinal sides 9a, 9b. Due to the undercut 26 associated with longitudinal side 9a, it is prevented in the working position A9 of the wall 9 from being released from the locking means 21a, 21b, on which the wall 9 is suspended in the working position A9, by a force acting in the y' direction from a storage space 28 formed on the intermediate floor 5 or by a force acting from top to bottom in the z' direction. The locking means 21a, 21b formed by bolts (see also Fig. 1) The bolts lie on a first straight line G1 with respect to their axes, and the joint means 13a, 13b formed by the bolts lie on a second straight line G2 with respect to their axes. Here, line G1 lies horizontally in space above line G2. From the Fig. In the working position A9 shown, the wall 9 is then decoupled from the closure 21 by a slight lifting in the z-direction, so that its undercut 26 no longer engages and so that the wall 9, from the raised position (not shown), then moves via a Fig. The intermediate position Z9 shown in section 3 then moves into one in the Fig. The horizontal position W9 shown in section 4 can be pivoted. The pivoting occurs about the pivot axis S13, which is defined by the joint means 13a and 13b. From the horizontal position W9 ( Fig. 4) The wall 9 can then be inserted horizontally in the y-direction under the intermediate floor 5, whereby the wall 9 is guided by the linear guide means 17a, 17b and is supported by its transverse sides 9c, 9d (see also Fig. 1) each slides on one leg S17a of the linear guide means 17a, 17b designed as L-shaped rails. In the Fig. Figure 5 shows the wall 9 almost in the aforementioned rest position A9, in which the wall 9 is inserted to such an extent that its web 25a is flush with the frame 2. Moving the wall 9 from the rest position R9 to the working position A9 is done in reverse.

[0027] From the Fig. As can be seen from Figure 5, the joint means 13a and the linear guide means 17a form a unit 29 in which the joint means 13a is connected to the linear guide means 17a, so that only the unit 29 needs to be mounted on the frame 3 of the scaffold 2 or on the intermediate floor 5.

[0028] According to one variant (not shown), the frames of the scaffold are also connected by several crossbeams. In this case, these crossbeams and the frames form a self-supporting structural unit.

[0029] According to another, not shown, embodiment, the linear guides are designed as slots in the frame of the rack, and the hinges as bolts projecting from the wall, which are received in the slots. Optionally, the locking mechanisms are also designed as bolts projecting from the wall, with corresponding recesses in the frame of the rack. This design of the order picking cart ensures that the storage space on each intermediate shelf is fully accessible across its entire width when the wall is in its rest position.

[0030] Furthermore, it is planned that the one in the Fig. 1. The picking trolley shown includes at least one handle by which it can be gripped for pushing or pulling.
