TRANSPORT DEVICE AND TRANSPORT VEHICLE

Description

[0001] The invention relates to a transport device with a transport vehicle. The transport vehicle comprises: a lower section having a base on which a box-shaped container can be placed, and a container fastening interface with which the at least one box-shaped container can be fastened to the lower section, two wheels arranged in a rear region of the transport vehicle on the lower section, with which wheels the transport vehicle can be supported and moved relative to a ground, and a frame section extending vertically upwards from the lower section, which frame section is arranged in the rear region and on which a handle is provided with which the transport vehicle can be manually tilted and moved relative to the ground.

[0002] Such a transport vehicle is known from the prior art, for example, from US Pat. No. 6,386,557 B1. For example, the "Sys-Roll" product available from TANOS GmbH is known as a transport vehicle for transporting box-shaped containers.

[0003] The transport vehicle mentioned above is typically used to transport one or more box-shaped containers to a location, for example a construction site. Tools, for example a power tool, and / or tool accessories are generally stored in the box-shaped container. The box-shaped containers are in particular designed such that they can be stacked on top of one another and coupled vertically in a tensile-resistant manner to form a stable vertical, in particular cuboid-shaped, stack. For this purpose, the box-shaped containers each have the same horizontal footprint and coupling means with which they can be coupled to one another. The stack can be placed with the bottommost box-shaped container on the floor of the transport vehicle and secured using the container fastening interface.For practical purposes, the stack is only attached to the transport vehicle with the lowest box-shaped container.

[0004] The transport vehicle can be manually tilted into a tilting position, in which the transport vehicle is tilted relative to the ground around a tilting axis defined by the wheels. In this position, the transport vehicle can be moved like a hand truck, in particular pushed or pulled. The transport vehicle can also be referred to as a "hand truck-like" or "sack barrow."

[0005] A combination of the transport vehicle and the goods to be transported, for example the box-shaped container mentioned above, shall be referred to as the transport device.

[0006] US 6,386,557 B1 describes a portable cooler caddy with a cup holder panel.

[0007] US 2014 / 0110447 A1 describes a foldable, removable tray for two-wheeled handcarts.

[0008] US 6,543,796 B1 describes a combined table and luggage rack for transporting luggage and serving as a work table.

[0009] DE 20 2007 002 551 U1 describes a laundry trolley with a cupboard that is limited at the top by a shelf.

[0010] One object of the invention is to facilitate the transport of devices required at the site of use.

[0011] The object is achieved by a conveying device according to claim 1. The conveying device comprises an elongated work table and a work table fastening interface provided on the conveying vehicle, with which the elongated work table can be fastened to the conveying vehicle in a vertical orientation in order to assume a transport position in which the elongated work table can be conveyed by the conveying vehicle.

[0012] This allows the transport vehicle to transport an elongated work table in addition to the box-shaped container. The box-shaped container and the work table can thus be transported as a single, manageable unit—the transport device.

[0013] Overall, this results in a compact and easy-to-handle transport device with which several devices required at the site - namely one or more box-shaped containers and the work table - can be transported.

[0014] Conveniently, the elongated work table can be fastened to the transport vehicle in a vertical orientation in the rear area using the work table fastening interface.

[0015] Because the work table can be attached to the rear of the transport vehicle - i.e. in the area where the wheels are located - the work table, when attached, is located in the area of the tilting axis of the transport vehicle, so that the torque required to tilt the transport vehicle can be kept low even when the work table is attached.

[0016] The work table can be completely removed from the transport vehicle without tools. The work table can be conveniently attached to the transport vehicle without tools. The box-shaped container can be conveniently removed (in particular completely) from the transport vehicle and / or attached to it without tools.

[0017] The work table has a fold-out table leg arrangement.

[0018] When attached, the elongated work table is aligned vertically, particularly with its longitudinal axis.

[0019] The work table attachment interface comprises a first attachment device arranged on the lower portion, wherein the first attachment device comprises an attachment structure engageable with a fastening element arranged on the work table, and wherein the transport vehicle has a support portion to which the work table can be attached with the fastening element in a horizontal orientation to assume a stationary working position.

[0020] Advantageous further training is the subject of the subclaims.

[0022] In the following explanations, reference is made to the x-direction, y-direction, and z-direction shown in the figures. The x-direction, y-direction, and z-direction are orthogonal to each other. The x-direction can also be referred to as the transverse direction, the y-direction as the longitudinal direction, and the z-direction as the vertical direction. Furthermore, the x-direction and the y-direction can also be referred to as horizontal directions. The reference system for these directions is the conveyor device 1 in an upright position.

[0023] The Figure 1shows a transport device 1 with a transport vehicle 2. The transport vehicle 2 comprises a lower section 3. The lower section 3 has a storage area 5 on which a box-shaped container 80 is placed. The storage area 5 is e.g. in the Figure 2 can be seen. An example is the Figure 1 a vertical stack 90 comprising two box-shaped containers 80 stacked and coupled to one another is placed on the storage area 5.

[0024] The lower section 3 further comprises a container fastening interface 6, with which the box-shaped container 80 or the vertical stack 90 is fastened to the lower section 3, for example.

[0025] The transport vehicle 2 further comprises two wheels 11 arranged in a rear region 7 of the transport vehicle 2 on the lower section 3, with which the transport vehicle 2 can be supported and moved, in particular in a tilted position relative to a floor 30. The term "rear region" refers in particular to that y-region of the transport vehicle 2 that is located near the transverse rear side 8 of the transport vehicle 2.

[0026] The transport vehicle 2 further comprises a frame section 14 extending vertically upward from the lower section 3 and arranged in the rear region 7. A handle 12 is provided on the frame section 14, with which the transport vehicle 2 can be manually tilted and moved relative to the ground 30.

[0027] The conveying device 1 further comprises an elongated work table 40 and a work table fastening interface 24 provided on the conveying vehicle 2, with which the elongated work table 40 is fastened to the conveying vehicle 2 in a vertical orientation in order to assume a transport position in which the elongated work table 40 can be conveyed by the conveying vehicle 2.

[0028] Further exemplary details are explained below.

[0029] First, the basic structure of the transport vehicle 2: The Figure 2 shows the transport vehicle 2 on its own—i.e., without a box-shaped container and without a work table. The transport vehicle 2 can also be provided as it is—i.e., on its own.

[0030] The transport vehicle 2 (without the handle 12) has, in a yz side view, essentially the shape of a U rotated by 90 degrees or the shape of a C. The lower section 3 and an upper section 16, which will be explained below, each represent horizontal legs in a yz side view, which are connected by the vertical frame section 14, expediently only by the vertical frame section 14.

[0031] The lower section 3 and the vertical frame section 14 together (without the handle 12) form a substantially L-shaped structure in a yz side view.

[0032] The extension of the vertical frame section 14 in the z-direction is greater than the extension of the lower section 3 in the y-direction and greater than the extension of the upper section 16 in the y-direction. The y-extension of the lower section 3 corresponds to the y-extension of the upper section 16. The vertical frame section 14 preferably occupies at least 60%, in particular at least 70%, of the z-extension of the transport vehicle 2 without the handle 12.

[0033] The transport vehicle 2 has a transverse front side 10, two longitudinal sides 9, and a transverse rear side 8. The lower section 3 is formed, for example, by a lower part 4, which has a substantially cuboidal, in particular flat, basic shape. The y- and x-extensions of the lower part 4 are each at least twice as large as the z-extension of the lower part 4. A wheel 11 is arranged on each of the longitudinal sides 9, specifically in the rear region 7 of the transport vehicle 2, i.e., near the rear side 8. The two wheels 11 have coaxially arranged axes of rotation aligned in the x-direction.

[0034] The lower part 4 has one, two, or more feet 39 on its underside, with which the transport vehicle 2 stands stably on a level floor in the stationary position. For example, the transport vehicle 2 stands only on the feet 39 in the stationary position, and in particular not on the wheels 11.

[0035] The transport vehicle 2 can assume a stationary position in which it rests stably on the ground. In the stationary position, the lower section 3 is aligned parallel to the ground 30 and the vertical frame section 14 is aligned perpendicular to the ground 30. The transport vehicle 2 can also assume a driving position in which it is tilted relative to the ground, for example by approximately 45 degrees. The transport vehicle 2 can be tilted relative to the ground 30 about the axis of rotation of the wheels 11. In the driving position, the two wheels 11 support the transport vehicle 2 relative to the ground 30 on which the transport vehicle 2 stands. In the driving position, the transport vehicle 2 can be set in motion by manually pushing or pulling. The transport vehicle 2 can therefore be handled like a hand truck and can also be described as sack barrow-like.

[0036] As already mentioned, in the Figure 1the conveying device 1 is shown, ie, the conveying vehicle 2 with attached work table 40 and box-shaped containers 80.

[0037] The conveying device 1 is here in a transport configuration in which the box-shaped containers 80 and the work table 40 are firmly attached to the conveying vehicle 2, so that the box-shaped containers 80 and the work table 40 are stably attached to the conveying vehicle 2 even in a driving position in which the conveying device 1 is tilted relative to the floor 30 and can be transported by the conveying vehicle 2. Conveniently, the work table 40 can be removed from the conveying vehicle 2 without tools in the transport configuration.

[0038] The work table 40 is located in the Figure 1in the transport position, in which the work table 40 is aligned with its longitudinal axis vertically—i.e., in the z-direction. The table plane of the work table 40 is aligned parallel to an xz-plane in the transport position. The x-extension of the work table 40 corresponds to the x-extension of the vertical frame section 14. In the transport position, the work table 40 rests against the vertical frame section 40 and expediently occupies the same x-range as the vertical frame section 40. In the z-direction, the work table 40 extends upwards from the lower section 3 in the transport position and preferably projects beyond the transport vehicle 2, in particular the upper section 16 and / or the handle 12.

[0039] In the transport position, the work table 40 is arranged in the rearward direction—i.e., in the y-direction toward the rear side 8—behind the vertical frame section 14. In the y-direction, the work table 40 is located in the transport position on the side of the vertical frame section 14 facing the rear side 8. The support surface 5 is located, for example, on the other side—i.e., on the side of the vertical frame section 14 facing the front side 10.

[0040] The vertical frame section 14 spans an xz plane. For example, the vertical frame section 14 has two parallel, column-shaped frame elements 15, which are designed as profiles. Preferably, the vertical frame section 14 consists of the two frame elements 15.

[0041] The two frame elements 15 each occupy the same y- and z-range and are offset from each other in the x-direction. The frame elements 15 are arranged near the rear side 8, i.e., in the rear area 7, in the y-direction and are located in the area of the long sides 9 in the x-direction. The two frame elements 15 are attached to the top of the lower part 4 and extend vertically upward.

[0042] The upper section 16 adjoins the vertical frame section 14 in the z-direction. By way of example, the upper section 16 comprises a table 18 integrated into the transport vehicle 1. The integrated table 18 represents, by way of example, the vertical upper end of the transport vehicle 2 (without the handle 12). The upper section 16 has, by way of example, four elongated, horizontal frame elements 17, which are, by way of example, designed as profiles. The frame elements 17 together form a horizontal frame section in the form of a rectangular frame, on which a table top 19 of the integrated table 18 is arranged. The upper section 16 essentially occupies the same xy area as the lower section 3. The upper section 16 expediently has a cuboid, in particular flat, basic shape.

[0043] As in the Figure 4As shown, two of the horizontal frame elements 17 are aligned parallel to the x-direction and two of the horizontal frame elements 17 are aligned parallel to the y-direction. A frame element 17 aligned parallel to the x-direction connects the two vertical frame elements 15 at their upper end and, together with the two frame elements 15, forms an inverted U in the xz side view. The two frame elements 17 aligned parallel to the y-direction extend forward in the y-direction from the upper ends of the vertical frame elements 15. The table top 19 is placed on the frame formed by the horizontal frame elements 17.

[0044] The Figures 3 and 4show the conveyor device 1 in a working configuration. In the working configuration, the work table 40 is removed from the work table mounting interface 24. Furthermore, the work table 40 is in a horizontal orientation; ie, its table plane is aligned parallel to an xy plane. The Figures 3 and 4 The position of the work table 40 shown can also be referred to as a stationary working position. In the working position, the work table 40 is supported at one of its end faces by the transport vehicle 2, in particular by the upper section 16.

[0045] By way of example, a support section 27 is provided on the upper section 16, on which the work table 40 is supported, in particular with a fastening element 41. The support section 27 is, for example, in the Figure 1and is present, for example, on one, several, or all of the horizontal frame elements 17. The support section 27 expediently comprises a groove, in particular a V-groove, into which the fastening element 41 can engage.

[0046] In the working configuration, the fastening element 41, with its fastening arrangement 48 (explained below), in particular with the fastening projections 53, expediently engages in the groove of the support section 27. In the working configuration, the work table 40 can be removed from the transport vehicle 2 without the need for tools.

[0047] Conveniently, a corresponding support section 27 is provided on the front side 10, the two longitudinal sides 9, and / or the rear side 8 of the transport vehicle 2, in particular the upper section 16, on which the work table 40 can be supported. The work table 40 can therefore be optionally attached to the front side 10, a first longitudinal side 9, a second longitudinal side 9, and / or the rear side 8.

[0048] In the Figures 3 and 4The work table 40 is attached to a longitudinal side 9 of the transport vehicle 2. The work table 40 is aligned with its longitudinal axis parallel to the y-direction. By way of example, the work table 40 is attached to the integrated table 18 and extends it in the y-direction. In an xy view, the work table 40 and the integrated table 18 essentially form an elongated, rectangular shape whose x-extension is a multiple, in particular at least twice or three times, the y-extension. The height of the work table is preferably equal to the height of the integrated table 18. On the end face facing away from the transport vehicle 2, the work table 40 is supported by a table leg arrangement 46, which will be explained in more detail below.

[0049] Next, the work table mounting interface 24 will be discussed in more detail, particularly with reference to the Figures 5 to 14 .

[0050] The work table attachment interface 24 serves to attach the work table 40 to the transport vehicle 2 in such a way that the work table 40 can be stably transported by the transport vehicle 2. Preferably, the work table attachment interface 24 is configured such that the work table 40, when attached, is fixed relative to the transport vehicle 2 in all spatial directions.

[0051] Conveniently, the work table attachment interface 24 is designed such that the elongated work table 40 is attached to the transport vehicle 2 in the vertical orientation in the rear region 7.

[0052] The work table mounting interface 24 comprises a first mounting device 20 and a second mounting device 21. The two mounting devices 20, 21 are, for example, in the Figure 8 shown

[0053] The first fastening device 20 is configured such that the work table 40 can be attached to the first fastening device 20 with the fastening element 41 in an orientation tilted relative to the vertical frame section 14, and by pivoting toward the vertical frame section 14, a vertical fixation to the first fastening device 20 is achieved. Using the second fastening device 21, the work table 40 can then be fixed horizontally, in particular to the vertical frame section 14.

[0054] In the Figures 5 to 7 The attachment of the work table 40 to the transport vehicle 2 is shown schematically. Figure 5 the work table 40 (removed from the transport vehicle 2) is moved in a tilted orientation relative to the frame section 14 with the fastening element 41 in front to the first fastening device 20, preferably by a linear movement in a yz direction.

[0055] The first fastening device 20 is designed such that the fastening element 41 can be attached to the first fastening device 20 in this tilted orientation of the work table 40, preferably only in this tilted orientation of the work table 40. By way of example, the first fastening device 20 has a slot 22 that is designed such that the fastening element 41 can be inserted into the slot 22 only in the tilted orientation of the work table 40.

[0056] In the Figure 6the work table 40 is pivoted towards the vertical frame section 14, specifically in a state in which the fastening element 41 is attached to the first fastening device 20. The fastening element 41 and the first fastening device 20 expediently define an axis extending in the x-direction, about which the work table 40 is pivotable. The work table 40 is preferably pivotable until it rests against the vertical frame section 14 and / or is aligned parallel to it. The first fastening device 20 is designed such that the fastening element 41 is linearly fixed in the pivoted state of the work table 40, and thus the work table 40 cannot be removed from the transport vehicle 2 by a linear movement, in particular not by a vertical linear movement.

[0057] In the Figure 7The work table 40 is fixed horizontally to the frame section 14 by the second fastening device 21—for example, by the strap 23—so that the work table 40 can no longer be pivoted. In this state, the work table 40 is fixed to the transport vehicle 2 in all spatial directions and cannot be removed therefrom.

[0058] To remove the work table 40, it is necessary to loosen the second fastening device 21 and to pivot the work table 40 away from the frame section 14 so that it Figure 5 The work table 40 can then be removed from the transport vehicle 2 by a linear movement in the yz direction.

[0059] An exemplary embodiment of the first fastening device 20 and the second fastening device 21 will be discussed in detail below: The first fastening device 20 is provided on the lower section 3 and arranged rearwardly behind the vertical frame section 14. By way of example, the first fastening device 20 comprises a fastening structure 29 with which the fastening element 41 can be engaged in order to fasten the work table 40 to the work table fastening interface 24.

[0060] The lower section 3 has an angled upper side 25 in the area of the first fastening device 20, which expediently extends over more than half of the x-extension of the lower part 4. The angled upper side 25 is, for example, in the Figure 9shown. The normal vector of the angled upper side 25 points in a yz-direction. The angled upper side 25 serves to prevent a work table 40 that is not properly attached to the first fastening device 20—for example, a work table 40 that is simply placed on the upper side 25—with its fastening element 41 from standing securely on the upper side 25, but instead from slipping off.

[0061] The Figure 9 shows the Figure 8 area marked "Y" in detail.

[0062] In the Figure 9 In particular, the first fastening device 20 can be seen, which comprises a slot 22 extending in the x-direction for receiving the fastening element 41. The slot 22 is expediently arranged in the y-direction directly behind the vertical frame section 14. The slot 22 is located on the angled upper side 25.

[0063] In the Figure 9The fastening element 41 can also be seen. The fastening element 41 is arranged on one end face of the work table 40. For example, the fastening element 41 is arranged on a transverse work table frame element 43, which is designed here as a profile element.

[0064] The fastening element 41 has a fastening arrangement 48. In a yz side view (in the transport position of the work table 40), the fastening arrangement 48 has an L-shaped basic configuration with a vertically extending first leg 51 and a second leg 52 extending obliquely downwards from the first leg 51 in a yz direction. Figure 14A yz side view of the fastening arrangement 48 is shown. By way of example, the fastening arrangement 48 comprises a plurality of L-shaped fastening projections 53 arranged next to one another in the x-direction, each having a corresponding first leg 51 and a second leg 52. By way of example, the fastening arrangement 48 comprises five fastening projections 53. Two adjacent fastening projections 53 are spaced apart from one another in the x-direction. The fastening arrangement 48 can be inserted into the slot 22.

[0065] The fastening element 41 further has a plate-shaped portion 54, with which the fastening element 41 is attached to the work table frame element 43. The fastening arrangement 48 is arranged on the side of the plate-shaped portion 54 facing away from the work table frame element 43. The fastening element 41 is expediently a one-piece part. The fastening arrangement 48, in particular the entire fastening element 41, is expediently made of a flexible material, in particular plastic.

[0066] The Figure 11 shows the Figure 10 area marked with "W" in detail.

[0067] In the Figure 11The slot 22 can be seen in particular. The fastening structure 29 is accessible via the slot 22. Two angled reinforcing structures 32, which are spaced apart from one another in the x-direction, are expediently located in the slot 22. Locking hooks 35 are provided between the reinforcing structures 32 and in front of and behind the reinforcing structures 32 in the x-direction. The reinforcing structures 32 and the locking hooks 35 are arranged in correspondence with the fastening projections 53, so that when the fastening element 41 is inserted into the slot 22, several fastening projections, in particular the first, third and fifth fastening projections, are located in the region of the locking hooks 35.

[0068] The Figure 14 shows a yz-section of the conveyor device 1. In the Figure 14In particular, the fastening structure 29 and the fastening element 41 engaging with the fastening structure 29 can be seen. The fastening structure 29 comprises a fastening surface 34, which is engaged behind by the fastening arrangement 48, in particular the second leg 52 of the fastening projections 53. The fastening surface 34 is formed by a horizontal projection. The horizontal projection can expediently be part of an L-shaped latching hook 35, which is spring-loaded on the rear wall of the fastening structure 29. Preferably, a plurality of L-shaped latching hooks are arranged next to one another in the x-direction, so that in each case one L-shaped latching hook can be brought into engagement with a fastening projection 53. Preferably, no L-shaped latching hook is present for every second fastening projection 53, in particular for the second and fourth fastening projection 53, and instead a reinforcing structure 32 is preferably provided.

[0069] The fastening arrangement 48 and the slot 22 are designed, in particular dimensioned, such that the fastening arrangement 48 can only be inserted into the slot 22 in the aforementioned tilted position of the work table 40. In order to engage the fastening arrangement 48 with the fastening structure 29, the work table 40 must be pivoted into a vertical orientation so that the fastening projections 53 engage behind the fastening surface 34.

[0070] The work table mounting interface 24 has a second mounting device 21 arranged on the vertical frame section 14. The second mounting device 21 is particularly in the Figures 12 and 13shown. The second fastening device 21 is arranged, by way of example, in the upper region of the vertical frame section 14. The second fastening device 21 comprises a belt 23, with which the work table can be fixed horizontally to the vertical frame section 14 in the transport position. The belt 23 is fastened, by way of example, to two anchoring points 79. The two anchoring points 79 are, by way of example, at the same height. By way of example, the belt 23 is laid transversely around the work table 40 in the transport position. In this state, the belt 23 has a U-shaped course in an xy view. The belt 23 has a closure element 28, with which it can be opened to release or receive the work table 40 and closed to fix the work table 40. By way of example, the closure element 28 is arranged in the middle of the belt 23 in the x-direction.

[0071] In the following, the handle 12 will be explained in more detail, in particular with reference to the Figures 15 to 17 The handle 12 is expediently bow-shaped, in particular U-shaped. The handle 12 has two outer sections 36, with which the handle is pivotably attached to the vertical frame section 14. The two outer sections 36 are connected via a central section 37 extending in the x-direction. Two sliding elements 38 are arranged on the central section 37, by way of example, with which the handle 12 can be supported against a floor when the transport vehicle 2 is tilted by 90 degrees about an x-axis.

[0072] When the work table 40 is attached to the work table attachment interface 24, the bow-shaped handle 12 expediently surrounds the work table 40. In particular, the work table 40 extends through a plane spanned by the handle 12.

[0073] The transport vehicle 2 has a positioning mechanism 26 with which the handle 12 can be positioned and fixed in at least two different pivoting positions. For example, the handle 12 can be fixed in three different pivoting positions by the positioning mechanism.

[0074] The Figures 15 to 17 show the handle 12 in three different pivoting positions in which the handle 12 can be fixed via the positioning mechanism 26.

[0075] The Figure 15shows a first pivoting position of the handle 12. This pivoting position can also be referred to as a fixing position. In the first pivoting position, the handle 12, in a state in which the work table 40 is attached to the first fastening device 20, limits the maximum tilt angle of the work table 40 such that a tilt angle that must be assumed by the work table 40 in order to release the fastening of the work table 40 from the work table fastening interface 24 cannot be assumed. The fixing position is also, for example, in the Figure 7 shown: in the Figure 7The handle 12 is in the locking position, thus limiting the tilt angle of the work table 40 so that it cannot be released from the first fastening device 20. In the locking position, the pivot angle (relative to the z-axis) of the handle 12 is, in particular, between 10 and 40 degrees. The handle 12, in particular the sliding elements 38, are expediently flush with the wheels 11 in the y-direction, so that the transport vehicle 2 can be positioned in an upright position with its rear side 8 as close as possible to a straight wall.

[0076] The Figure 16shows a second pivoting position of the handle 12. The second pivoting position has a larger pivoting angle than the first pivoting position and is particularly practical for loading the transport vehicle 2 into a vehicle. In particular, the transport vehicle 2 can be driven with its rear side 8 up to the loading edge of a car, for example a small van, and then tilted about the axis of rotation defined by the wheels 11 until the handle 12, in the second pivoting position, rests on the loading area of the car, in particular with its sliding elements 38. The transport vehicle 2 can then be lifted by its lower part 4 and pushed into the loading space of the car. There, the transport vehicle 2 can be righted again so that it assumes the vertical standing position.The handle 12 can then be moved into the first pivot position so that the transport vehicle 2 can be positioned with its rear side 8 as close as possible to a wall in the cargo space. The described method for loading the transport vehicle 2 is also applicable to the transport device 1, i.e., in the case where the work table 40 and / or one or more box-shaped containers 80 are attached to the transport vehicle 2.

[0077] The Figure 17 shows a third pivot position of the handle 12. In the third pivot position, the handle 12 is oriented vertically upwards; the pivot angle is 0 degrees. In this pivot position, the transport vehicle 2 can be handled and transported particularly well without the work table 40.

[0078] The Figures 5 and 6show the handle 12 in a fourth pivot position. Preferably, the handle 12 cannot be fixed in the fourth pivot position. In the fourth pivot position, the handle 12 assumes a pivot angle of greater than 90 degrees and / or less than 170 degrees.

[0079] The fourth pivot position allows a tilt angle of the work table 40 at which tilt angle the work table 40 can be attached to and removed from the work table attachment interface 24. As shown in the Figure 5 As shown, in the fourth pivoting position of the handle 12, the work table 40 can be pushed forward to the first fastening device 20 by the handle 12 with its fastening element 41.

[0080] The Figure 3shows the handle 12 in a fifth pivot position. Preferably, the handle 12 cannot be fixed in the fifth pivot position. In the fifth pivot position, the handle 12 assumes its maximum pivot angle, for example, a pivot angle of greater than 160 degrees, and advantageously rests against the vertical frame section 14.

[0081] With reference to the Figures 18 to 20 An exemplary design of the positioning mechanism 26 will be explained below.

[0082] The positioning mechanism 26 is expediently designed to fix the handle 12 in one or more predetermined pivot positions, in particular two or three predetermined pivot positions, so that it is firmly held in the one or more predetermined pivot positions. The pivot positions in which the handle 12 can be fixed are in particular the first, second, and / or third pivot positions. Preferably, the positioning mechanism is designed such that the fixing of the handle 12 occurs automatically when the handle 12 is moved into a predetermined pivot position.

[0083] By way of example, the positioning mechanism 26 has a locking device 71 arranged on the handle 12 with a locking element 73, which is brought into engagement with a locking structure arranged on the vertical frame section 14 at one or more predetermined pivot angles. The locking element 73 is expediently preloaded by a spring element (not shown in the figures) so that it engages automatically with the locking structure when the handle assumes a predetermined pivot angle.

[0084] By way of example, the locking structure comprises a plurality of holes 76, 77, 78 which are formed in the Figure 20are shown. The locking device 71 comprises, as a locking element 73, by way of example, a locking bolt which can be selectively positioned over one of the holes 76, 77, 78 by pivoting the handle 12, so that the locking bolt snaps into this hole, thereby fixing the handle 12 in the associated pivot position. The holes 76, 77, 78 expediently lie on a circular segment-shaped path that is traversed by the locking element 73 when the handle 12 is pivoted. Preferably, the hole 77 is associated with the first pivot position, the hole 76 with the second pivot position, and the hole 78 with the third pivot position.

[0085] The locking device 71 expediently has an actuating portion 72, with which the engagement of the locking element 73 in the locking structure—and thus the fixation of the handle 12 in a specific pivot position—can be manually released. For example, the actuating portion 72 is a knob with which the locking bolt can be pulled out of a hole 76, 77, 78.

[0086] The locking device 71 is expediently arranged in an end region of an outer section 36 of the handle 12. The actuating section 72 is expediently arranged on a side of the outer section 36 facing away from the frame section 14, and the locking element 73 is arranged on a side of the outer section 36 facing the frame section 14. The locking device 71 preferably extends through the outer section 36. For example, a locking device 71 is present on each of the two outer sections 36 of the handle.

[0087] By way of example, the holes 76, 77, 78 are arranged on a plate-shaped part 70, which is expediently arranged between the vertical frame section 14, in particular a frame element 15, and the handle 12. The plate-shaped part 70 is in particular fastened to the vertical frame section 14. Expediently, two plate-shaped parts 70 are provided, each plate-shaped part 70 being arranged on a different longitudinal side 9 of the transport vehicle 2, in particular of the vertical frame section 14, expediently on a different frame element 15.

[0088] The positioning mechanism 26 further has an angled surface 75, over which the locking element 73 is guided and thereby pretensioned when the handle 12 is pivoted. The angled surface 75 is expediently arranged such that, when the handle 12 is pivoted from the aforementioned fourth pivot position, the locking element 73 is first guided over the angled surface 75 before the locking element 73 reaches the locking structure, in particular one of the holes 76, 77, 78. The angled surface 75 is exemplarily formed as a section of the plate-shaped part 70, in particular as an angled tab.

[0089] The angled surface 75 makes it possible to move the handle 12 from the fourth pivot position into the second pivot position without having to manually actuate the locking device 71, in particular the actuating section 72.

[0090] Each plate-shaped part 70 further comprises, by way of example, an anchoring point 79 for the belt 23, in particular an anchoring slot, which preferably runs vertically and is arranged in particular in the lower region of the plate-shaped part 70 - that is to say below the holes 76, 77, 78.

[0091] Furthermore, a pivot bearing 74 is provided on the handle 12, in particular on the outer portion 36, via which the handle 12 is pivotably mounted on the vertical frame portion 14, in particular via the plate-shaped part 70. Conveniently, a respective pivot bearing 74 is provided on both outer portions 36 of the handle 12.

[0092] In the following, the work table 40 will be discussed in more detail, in particular with reference to the Figures 3 and 4 , where the work table is aligned with its longitudinal axis in the x-direction.

[0093] The work table 40 has an elongated, in particular rectangular, basic shape. The work table 40 is expediently at least 1.5 times, in particular twice, as long as it is wide. The work table 40 has a frame-shaped work table frame comprising longitudinal work table frame elements 42 and transverse work table frame elements 43. The longitudinal work table frame elements 42 and the transverse work table frame elements 43 are expediently rod-shaped and, in particular, designed as profiles. A table top 44 is placed on the frame-shaped work table frame.

[0094] The work table 40 has the fold-out table leg assembly 46, which is exemplary U-shaped. The vertical sections of the table leg assembly 46 (in the unfolded state) should also be referred to as table legs. The table leg assembly 46 is expediently arranged on the underside of the work table 40, preferably in the region of an end face of the work table 40. The table leg assembly 46 is pivotally mounted, in particular, on the work table frame. The pivot axis of the table leg assembly 46 is expediently aligned parallel to the transverse work table frame elements 43. The work table frame and the underside of the table top 44 define a receiving volume that accommodates the table leg assembly 46 in the folded state, in particular completely. The folded state of the table leg assembly 46 can also be referred to as the transport position, and the unfolded state as the working position.

[0095] The work table 40 has fixing elements 45 with which the table leg arrangement 46 can be fixed in the working position. For example, the fixing elements 45 are plate-shaped elements, each provided at the upper end of a table leg and mounted so as to be rotatable about the respective table leg. The normal vector of the plate-shaped elements is always aligned orthogonally to the longitudinal axis of the table legs; ie, each table leg always lies in the plate plane of the associated plate-shaped element. The plate-shaped elements can be moved into a locking position and an unlocking position by pivoting. In the locking position, which is, for example, in the Figures 3 and 4As shown, the plate-shaped elements are aligned parallel to the longitudinal work table frame elements 42 and rest with their upper sides against the underside of the table top 44, so that the table leg assembly 46 is locked in the unfolded position and cannot be folded in. In the unlocked position, the plate-shaped elements are aligned parallel to the transverse work table frame elements 43, so that the table leg assembly 46 can be folded in.

[0096] The work table 40 is configured to correspond to the integrated table 18. In particular, the work table frame elements 42, 43 and the horizontal frame elements 17 of the integrated table 18 comprise the same profiles or profiles of the same type, preferably of the same cross-section.

[0097] Preferably, the work table frame elements 42 also comprise one or more support sections 27, for example a groove, in particular a V-groove, on which one or more further work tables 40 can be supported with their fastening element 41.

[0098] The table top 44 expediently has a hole pattern, in particular a regular hole pattern, preferably a hole grid. Preferably, the table top 19 of the integrated table 18 has a hole pattern, in particular a regular hole pattern, preferably a hole grid. Expediently, the hole patterns, in particular the hole grids, of the two table tops 44, 19 have the same hole spacing.

[0099] In the following, a method will be described how the conveying device 1 is changed from the transport configuration (cf. Fig. 1 ) into the working configuration (see Fig. 3 ) can be moved.

[0100] First, the attachment of the work table 40 to the work table attachment interface 24 is released. For this purpose, the second attachment device 21—here, the strap 23—is released. Furthermore, the first attachment device 20 is released by moving the work table 40 into a predetermined tilted position in the direction away from the vertical frame section 14. To enable this tilted position, the handle 12 is expediently moved into a corresponding pivoted position, for example, into the fourth pivoted position explained above.

[0101] The work table 40 can then be completely removed from the transport vehicle 2. Next, the table leg assembly 46 is unfolded and locked in the unfolded state by pivoting the fixing elements 45.

[0102] The work table 40 is then brought into a horizontal orientation and attached with its fastening element 41 to a support section 27 of the conveying vehicle 2. The conveying device 1 is then in the working configuration.

[0103] The container mounting interface 6 and the box-shaped container 80 will be explained in more detail below, in particular with reference to the Figure 1 .

[0104] The container fastening interface 6 serves to fasten the box-shaped container 80 to the lower section 3, in particular the lower part 4, of the transport vehicle 2, preferably in such a way that the box-shaped container 80 is fixed in all spatial directions.

[0105] The container fastening interface 6 is expediently designed such that the container 80 can be fastened to and / or detached from the container fastening interface 6 without tools.

[0106] For example, the container fastening interface 6 has a movable coupling element 91, which is designed as a rotary latch, in particular as a T-shaped rotary latch. The movable coupling element 91 can be manually moved into various rotational positions in order to selectively secure or release the fastening of the container 80 to the transport vehicle 2.

[0107] The movable coupling element 91 is exemplarily attached to the front side 10 of the lower section 3 and is preferably rotatably mounted, in particular about a y-axis of rotation.

[0108] The container attachment interface 6 preferably further comprises a non-movable coupling structure 92, which, for example, comprises two recesses arranged in the support surface 5. The non-movable coupling structure 92 can be brought into engagement with lower container coupling means 82, in particular feet 85, which will be explained below.

[0109] The container fastening interface 6 and / or the transport vehicle 2 are designed in particular such that when attaching and / or removing one or more containers 80 to the container fastening interface 6, the transport vehicle 2, in particular the vertical frame section 4, does not have to be dismantled or converted.

[0110] Preferably, the container fastening interface 6 and / or the container 80 is designed such that the container 80, in a state fixed to the transport vehicle 2, is fastened to the transport vehicle 2 with its underside and front side, in particular only with its underside and front side.

[0111] Now to the container 80: The container 80 has a cuboid basic shape. For example, the container 80 has a lower part 101 and a lid 102 placed on the lower part 101. The lid 102 is expediently hinged to the lower part 101. Preferably, the lower part 101 and the lid 102 have the same horizontal outer contour. A carrying handle 103, in particular a fold-out carrying handle, is provided on the upper side of the container 80.

[0112] The container 80 has upper container coupling means 81 and lower container coupling means 82. The container coupling means 81, 82 are particularly in the Figures 21, 22 and 23 can be seen. By way of example, the upper container coupling means 81 are designed to correspond to the lower container coupling means 82, so that a further container 80 equipped with identical container coupling means can be placed on the present container 80 and fastened to the upper container coupling means 81 of the present container 80 by means of the lower container coupling means 82 of the further container 80, in particular in such a way that the two containers 80 are fixed to one another in all spatial directions and form a stable vertical stack 90.

[0113] The lower container coupling means 82 comprise, in particular, a first non-movable coupling structure 84, for example, a coupling projection that can be engaged with the movable coupling element 91. The non-movable coupling structure 84 is arranged, in particular, on the front side of the container 80.

[0114] The lower container coupling means further comprise a second non-movable coupling structure 85, for example feet, which can be engaged with the non-movable coupling structure 92 and are arranged on the underside of the container 80.

[0115] The Figure 22shows a vertical section through the box-shaped container 80 in a state in which its second non-movable coupling structure 85, designed as support feet, is engaged with the non-movable coupling structure 92 of the container interface 6. By way of example, the non-movable coupling structure 92 has a projection that is engaged behind by the support feet, in particular the rear support feet, expediently only the rear support feet.

[0116] The upper container coupling means 81 expediently comprise a movable coupling element 83, for example a rotary latch, in particular a T-shaped rotary latch, which is expediently designed to correspond to the movable coupling element 91. The movable coupling element 83 can in particular be engaged with the first non-movable coupling structure 84 of a further container 80. Furthermore, the movable coupling element 83 can serve to lock the lid 102.

[0117] The upper container coupling means 81 preferably further comprise a third non-movable coupling structure 86. The third non-movable coupling structure 86 can conveniently be engaged with the second non-movable coupling structure 85 of a further container 80. The third non-movable coupling structure 86 preferably comprises one or more recesses and is arranged on the upper side of the container 80.

[0118] The container 80 is in particular designed such that the container 80, in a state fixed to another container 80, is fastened to the other container 80 with its underside and front side, in particular only with its underside and front side.

[0119] The containers 80 described above can, for example, be designed in accordance with the containers described in EP2315701B1.
