TRANSPORT DEVICE AND TRANSPORT VEHICLE

Description

[0001] The invention relates to a conveying device comprising a conveying vehicle and a vertical stack of box-shaped containers coupled to one another.

[0002] The transport vehicle includes: a vehicle body with a lower part and a vertical frame section extending upwards from the top of the lower part, the lower part having a base and a container fastening interface with which the vertical stack placed on the base with its lowermost box-shaped container can be fastened to the lower part, a handle arranged on the vehicle body with which the transport vehicle can be placed in a tilting position, and two wheels arranged on the lower part with which the transport vehicle can be supported against a ground in the tilting position and can be moved relative to the ground.

[0003] Such a transport vehicle is known from the state of the art. For example, the "Sys-Roll" product available from TANOS GmbH is a well-known transport vehicle for transporting box-shaped containers.

[0004] 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.Conveniently, the stack is secured to the transport vehicle with only the lowest container. The vehicle body, in particular the vertical frame section, represents a permanently integral structure; i.e., the vehicle body, in particular the vertical frame section, remains unchanged in its construction when a box-shaped container is attached and removed. The box-shaped container can conveniently be removed from and / or attached to the transport vehicle without the need for tools.

[0005] 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."

[0006] 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.

[0007] US 7,367,571 B1 describes a machine tool stand and / or workbench, socket panel, lighting supply and modular task box system, combined in an integrated system.

[0008] US 6,386,557 B1 describes a portable cooler caddy with a cup holder panel.

[0009] An object of the invention is to provide the conveying device with a further function while maintaining its compact and simple design.

[0010] The object is achieved by a conveying device according to claim 1. The lower part of the conveying device has on its underside a plurality of feet on which the conveying vehicle stands in an upright position.

[0011] The transport device can therefore be placed stably on the ground in an upright position and remain in place. The transport device can thus form an at least temporarily stationary workstation with which various tasks can be performed at the site.

[0012] The lower part has a plurality of feet on its underside and the transport vehicle is designed to support itself in an upright position with the feet and not with the wheels relative to the ground, wherein the lower part comprises in a rear region a first fastening device of a work table fastening interface with which an elongated work table can be attached in a vertical orientation to the transport vehicle, wherein the first fastening device has a slot and a fastening structure accessible via the slot.

[0013] As explained below, the conveyor can, for example, serve to support a work table in a horizontal working position. Furthermore, the conveyor can have an integrated table on which work can be performed. The tools and / or accessories required for the work are provided, in particular, in the box-shaped containers. The conveyor thus not only serves to transport the box-shaped containers, but can also be used as a temporarily stationary workstation or part of a temporarily stationary workstation.

[0014] Advantageous further training is the subject of the subclaims.

[0015] Exemplary details and embodiments are explained below with reference to the figures. Herein: Figure 1 shows a conveying device, Figure 2 shows a lower part in a perspective view from above, Figure 3 shows the lower part in a perspective view from below, Figure 4 shows a conveying vehicle in a perspective view from above, Figure 5 shows the conveying vehicle in a perspective view from below, Figure 6 shows the conveying vehicle with an extension arrangement, Figure 7 shows the conveying vehicle with an inserted additional container, Figure 8 shows the conveying vehicle in a rear view, Figure 9 shows the conveying device in a rear view, Figure 10 shows a fastening device in a detailed view, Figure 11 shows the conveying device in a perspective view from above, Figure 12 shows the fastening device in a detailed view, Figure 13 shows the fastening device in a sectional view, Figure 14 shows the conveying device in a working configuration in a perspective view from above,and Figure 15 shows the conveyor in the working configuration in a perspective view from below, Figure 16 shows a box-shaped container, Figure 17 shows a sectional view of a box-shaped container attached to the lower part, and Figure 18 shows a box-shaped container placed on the lower part.

[0016] 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 transport vehicle 2 or the transport device 1 in an upright position.

[0017] The Figure 1shows a transport device 1 with a transport vehicle 2 and a vertical stack 90 of box-shaped containers 80 coupled to one another.

[0018] The transport vehicle 2 comprises a vehicle body with a lower part 4 and a vertical frame section 14 extending upwards from the top of the lower part 4. The lower part 4 has a storage area 5 and a container fastening interface 6. The vertical stack 90 placed on the storage area 5 with its lowermost box-shaped container 80 is fastened to the lower part 4 by the container fastening interface 6.

[0019] The transport vehicle 2 further comprises a handle 12 arranged on the vehicle body, with which the transport vehicle 2 can be placed into a tilting position. Furthermore, the transport vehicle 2 comprises two wheels 11 arranged on the lower part 4, with which the transport vehicle 2 can be supported against a ground in the tilting position and moved relative to the ground.

[0020] The lower part 4 has at least one base 39, 39A on its underside, on which the transport vehicle 2 stands in an upright position.

[0021] Further exemplary details are explained below.

[0022] First, the basic structure of the transport vehicle 2: The transport vehicle 2 is on its own - i.e. without the box-shaped containers 80 - in the Figures 4 and 5 and has a transverse front side 10, two long sides 9 and a transverse rear side 8.

[0023] The transport vehicle 2 can assume a stationary position in which it rests securely on the ground. In the stationary position, the lower part 4 is aligned parallel to the ground, and the vertical frame section 14 is aligned perpendicular to the ground. The transport vehicle 2 can also assume a traveling position in which it is tilted relative to the ground, for example, by approximately 45 degrees. In the traveling 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 having a hand truck design.

[0024] The vehicle body, which consists, for example, of the lower part 4, the vertical frame section 14 and an integrated table 18, has, in a yz side view, essentially the shape of a U rotated by 90 degrees or the shape of a C. In a yz side view, the lower part 4 and the integrated table 18 each represent horizontal legs which are connected by the vertical frame section 14, expediently only by the vertical frame section 14.

[0025] The lower part 4 and the vertical frame section 14 together (without the handle 12) form a substantially L-shaped structure in a yz side view.

[0026] The extension of the vertical frame section 14 in the z-direction is greater than the extension of the lower part 4 in the y-direction and greater than the extension of the integrated table 18 in the y-direction. The y-extension of the lower part 4 corresponds to the y-extension of the integrated table 18. The vertical frame section 14 preferably occupies at least 60%, in particular at least 70%, of the z-extension of the vehicle body or the transport vehicle 2 without the handle 12.

[0027] The vertical frame section 14 is arranged in the rear region 7 of the transport vehicle 2. The integrated table 18 is expediently supported relative to the lower part 4 only by the vertical frame section 14 arranged in the rear region 7. Between the integrated table 18 and the lower part 4, there is thus a completely free volume in front of the vertical frame section 14 in the y-direction for accommodating one or more box-shaped containers 80. Except for the frame section 14 arranged in the rear region 7, the volume present between the integrated table 18 and the lower part 4 is preferably completely free.

[0028] The vehicle body comprising the lower part 4, the vertical frame section 14, and the integrated table 18 preferably represents a permanently integral structure that remains unchanged during the removal and / or attachment of a box-shaped container 80 to the container attachment interface 6. Modification of the vehicle body, in particular of the vertical frame section 14 and / or the integrated table 18, is not required for the removal and / or attachment of the box-shaped container 80 to the container attachment interface 6. Conveniently, the integrated table 18 and / or the vertical frame section 14 cannot be removed from the vehicle body without tools.

[0029] The Figures 2 and 3show the lower part 4. The lower part 4 has a substantially cuboidal, particularly flat, basic shape. The y-extension and the x-extension of the lower part 4 are each at least twice as large as the z-extension of the lower part 4.

[0030] The lower part 4 comprises, for example, a lower part body manufactured as an injection-molded part, preferably in one piece, which provides the support surface 5. Alternatively, the lower part 4 or the lower part body of the lower part 4 can also be designed as a sheet metal part, in particular as a bent sheet metal part.

[0031] The upper side of the lower part body expediently represents a continuous, particularly relief-shaped surface and is preferably substantially closed. The underside of the lower part body is, for example, substantially open. A plurality of reinforcing ribs are expediently accessible via the underside.

[0032] The preferably one-piece base body has various integrated structures, in particular the U-shaped recess 133, recess 131, footprint 5, handle assembly 134, non-movable coupling structure 92, wheel attachment portions 136, pull-out attachment interface 137, first attachment device 20, angled top portion 25 and / or rack attachment portions 138 explained below.

[0033] A movable coupling element 91, the feet 39, 39A, the vertical frame section 14 and / or the wheels 11 are attached to the preferably one-piece lower body, as will be explained in more detail below.

[0034] First, regarding the support surface 5: The support surface 5 is essentially rectangular and preferably as large as the underside of the box-shaped container 80. A non-movable coupling structure 92 is present in the support surface 5, which is part of the container fastening interface 6, which will be explained in more detail below. By way of example, the non-movable coupling structure 92 comprises two elongated recesses arranged in the region of the longitudinal sides 9, which extend in the y-direction.

[0035] In the support surface 5, there is an exemplary recess 131 which provides a container receiving volume in which an additional container 132 can be accommodated, which is smaller than the box-shaped container 80. The Figure 7shows the transport vehicle 2 with the additional container 132 inserted. The additional container 132 can be used loosely, in particular. With the additional container 132 inserted, the box-shaped container 80 can preferably be placed on the support surface 5 and fastened to the lower part 4 via the container fastening interface 6. The box-shaped container 80 then expediently covers the additional container 132.

[0036] By way of example, the additional container 132 is a smaller version of the box-shaped container 80, so that the description below of the box-shaped container 80 also applies to the additional container 132. For example, accessories, in particular tool accessories, can be provided in the additional container. The recess 131 is, by way of example, cuboid-shaped. Because the recess 131 is located in the support surface 5, a substantially frame-shaped support surface 5 results.

[0037] The support surface 5 is surrounded by the U-shaped elevation 133. The U-shaped elevation 133 is open toward the front. The legs of the U-shaped elevation 133 represent upper sections of the long sides 9 of the lower part 4. By way of example, the vertical frame section 14 extends upward from the U-shaped elevation 133.

[0038] The lower part 4 has frame attachment sections 138 to which vertical frame elements 15 of the vertical frame section 14 are attached. The frame attachment sections 138 comprise, for example, openings that are preferably arranged at the two corners of the U-shaped elevation 133. The openings are, for example, L-shaped. The vertical frame elements 15 are inserted into the openings.

[0039] The lower part 4 expediently has four feet 39, 39A on its underside, with which the transport vehicle 2 stands stably on a level floor when stationary. The feet 39, 39A are not wheels. The feet 39 have, for example, a cylindrical shape and are aligned with their cylinder axis or longitudinal axis parallel to the z-direction. The foot 39A is preferably height-adjustable, and the other three feet 39 are expediently not height-adjustable. The foot 39A has, in particular, a screw section with which the foot 39A is attached to a thread on the lower part body, so that the height of the foot 39A can be changed by a screwing movement. The feet 39, 39A are expediently arranged in the four corner regions of the underside of the lower part 4.

[0040] The transport vehicle 2 is designed to support itself in the upright position with the support feet 39, 39A and in particular not with the wheels 11 against the ground. For this purpose, the support feet 39, 39A extend further downward in the vertical direction than the wheels 11; i.e., the support feet 39, 39A represent the lowest point of the transport vehicle 2 in the upright position of the transport vehicle 2. The transport vehicle 2 only stands on the wheels 11 in a tilted position; in the tilted position, the transport vehicle 2 expediently does not stand on any of the support feet 39, 39A.

[0041] The lower part 4 has a handle arrangement 134 on its front side 10 with a fully encompassing carrying handle 135. The handle arrangement 134 is expediently designed as a lower edge of the lower part 4, in particular of the one-piece lower part body, that protrudes in the y-direction. The handle arrangement 134 expediently extends over more than half, more than 70 percent, or over the entire x-extension of the front side 10 of the lower part 4.

[0042] The handle assembly 134 is formed on the underside as a grippable structure extending in the y-direction, which exemplarily comprises two spaced-apart walls running parallel to each other in the x-direction, which are expediently connected to each other via a plurality of ribs. In the y-direction behind the handle assembly 134, one or more free spaces are expediently provided in the lower part 4, into which the fingers of a user can be accommodated when gripping the handle assembly 134.

[0043] The fully encircling carrying handle 135 is present, for example, only in the central x-region of the lower part 4 and is expediently formed by a web-shaped section that bridges a recess present on the front side. An opening is formed between the carrying handle 135 and the front side of the recess, through which a user can guide their fingers when grasping the carrying handle 135.

[0044] The lower part 4 has a wheel attachment section 136 on each of its two longitudinal sides 9, with one of the wheels 11 being attached to each wheel attachment section 136. The wheel attachment sections 136 are expediently designed as downwardly open recesses in the longitudinal sides 9 of the lower part and are preferably arranged in the rear region 7. Accordingly, a wheel 11 is arranged on each of the longitudinal sides 9 of the lower part 4, 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.

[0045] The following will discuss the container fastening interface 6 present on the lower part 4 in more detail. By way of example, the container fastening interface comprises a movable coupling element 91 that can be selectively moved into a locked position or a released position by user actuation. In the locked position, the coupling element 91 engages with a first non-movable coupling structure arranged on the box-shaped container 80. In the released position, the coupling element 91 releases the first non-movable coupling structure, so that the box-shaped container 80 can be removed from the lower part 4.

[0046] The movable coupling element 91 is exemplified as a rotary latch, in particular as a T-shaped rotary latch. The movable coupling element 91 is preferably a body movably mounted on the lower part 4, but is itself rigid. The movable coupling element 91 can be manually moved into various rotational positions to selectively secure or release the attachment of the container 80 to the transport vehicle 2.

[0047] The movable coupling element 91 is mounted, for example, on the front side 10 of the lower part 4 and is preferably rotatably mounted, in particular about a y-axis of rotation. The movable coupling element 91 is expediently arranged in the recess on the front side 10.

[0048] The container attachment interface 6 preferably further comprises the non-movable coupling structure 92 already mentioned above. The non-movable coupling structure 92 can be brought into engagement with lower container coupling means 82 explained below.

[0049] The Figure 17 shows 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.

[0050] 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.

[0051] In the following, the first fastening device 20 present on the lower part will be discussed. The first fastening device 20 is particularly shown in the Figures 8 to 13 shown.

[0052] The first fastening device 20 is part of a work table fastening interface 24, with which an elongated work table 40 can be attached in a vertical orientation to the transport vehicle 2. The first fastening device 20 comprises a slot 20 and a fastening structure 29 accessible via the slot 20, which can be engaged with a fastening element 41 of the work table 40 in order to fasten the work table 40 to the work table fastening interface 24. The first fastening device 20 is arranged rearwardly behind the vertical frame section 14.

[0053] The fastening arrangement 48 and the slot 22 are preferably designed such that the fastening arrangement 48 can only be inserted into the slot 22 in the above-mentioned tilted position of the work table 40.

[0054] The Figure 10 shows the Figure 9area marked "Y" in detail. For better visibility, the work table 40 is Figures 9 and 10 shown in a position in which the fastening element 41 is not inserted into the slot 22. When the work table 40 is correctly attached to the transport vehicle 2, the fastening element 41 is inserted into the slot 22.

[0055] As in the Figure 10 As can be seen, the slot 22 extends in the x-direction and is arranged in the y-direction immediately behind the vertical frame section 14. The slot 22 is located on an angled top section 25. The normal vector of the angled top section 25 points in particular in a yz-direction. In the Figure 10The fastening element 41 can also be seen, which has a particularly hook-shaped fastening arrangement 48 with, for example, a plurality of L-shaped fastening projections 53. The fastening structure 29 is designed such that it can be brought into engagement with the fastening arrangement 48, in particular the fastening projections 53, so that the work table 40 is fixed to the lower part 4 at least in a linear direction, in particular the vertical direction.

[0056] The Figure 12 shows the Figure 11 area marked with "W" in detail.

[0057] In the Figure 12The 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.

[0058] The Figure 13shows a sectional view of the first fastening device 20 with inserted fastening element 41. The fastening structure 29 comprises a fastening surface 34, which is engaged behind by the fastening arrangement 48. The fastening surface 34 is provided 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 an 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.

[0059] In the Figure 6The transport vehicle 2 is shown with a pull-out arrangement 150. The pull-out arrangement 150 is arranged above the container fastening interface 6 and expediently below the integrated table 18 on the vertical frame section 14. The pull-out arrangement 150 comprises a pull-out unit 151 with an extendable container receiving element 152 for, in particular, loosely receiving a box-shaped container 80. The container receiving element 152 is designed in particular as a tray, drawer, or compartment.

[0060] The pull-out unit 151 further comprises a pull-out mechanism 153, in particular a telescopic pull-out mechanism. The pull-out unit 151 is attached via a detachable connection, in particular a screw connection, to a support assembly 155, which expediently comprises two support arms 154 and is part of the pull-out assembly 150.

[0061] The lower part 4 preferably has a pull-out fastening interface 137 to which the pull-out unit 151 (in a state removed from the support arrangement 155) can be fastened, in particular via the pull-out mechanism 153. The pull-out unit 151 can expediently also be provided without the support arrangement 155 and fastened directly to the pull-out fastening interface 137, so that the pull-out container receiving element 152 is provided directly on the lower part 4. In this state, the support surface 5 is expediently covered by the pull-out unit 151 and can no longer be used to deposit the box-shaped container 80.

[0062] The pull-out fastening interface 137 is arranged, for example, on the inner sides of the legs of the U-shaped elevation 133. The U-shaped elevation 133 is expediently configured such that the pull-out unit 151 fits into the space provided between the legs of the U-shaped elevation 133. The pull-out fastening interface 137 expediently comprises at least one, in particular three, holes on each inner side, with which the pull-out unit 151 can be fastened to the lower part 4 via screw connections.

[0063] The vertical frame section 14 and the integrated table 18 will be discussed below: The vertical frame section 14 spans an xz plane. By way of example, the vertical frame section 14 comprises two elongated vertical frame elements 15 extending vertically upward from the lower part 4 and running parallel to one another. The vertical frame section 14 preferably consists of the two frame elements 15.

[0064] The two vertical frame elements 15 each occupy the same y- and z-range and are offset from each other in the x-direction. The vertical frame elements 15 are each 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 vertical frame elements 15 are attached to the top of the lower part 4 and extend vertically upward.

[0065] The vertical frame elements 15 are designed as profiles, in particular as metal profiles.

[0066] The table 18 integrated into the vehicle body adjoins the vertical frame section 14 in the z-direction. The integrated table 18 represents the vertical upper end of the vehicle body—in particular, the transport vehicle 2 without the handle 12. The integrated table 18 expediently represents the vertically highest point of the transport vehicle 2 without the handle 12. The integrated table 18 is optional. Instead of the integrated table 18, for example, a stiffening element could also be provided between the two vertical frame elements 15.

[0067] The integrated table 18 has four elongated, horizontal frame elements 17A, 17B. The horizontal frame elements 17A, 17B are designed, for example, as profiles, in particular as metal profiles. The frame elements 17 together form a horizontal frame section in the form of a rectangular frame, on which the table top 19 of the integrated table 18 is arranged, in particular placed. The integrated table 18 essentially occupies the same xy area as the base part 4. The integrated table 18 expediently has a cuboid, in particular flat, basic shape.

[0068] The horizontal frame section defines an xy-plane that is orthogonal to the xz-plane defined by the vertical frame section 14. The horizontal frame section is attached to the upper end of the vertical frame section 14, for example to the two vertical frame elements 15. The integrated table 18 is attached, in particular, to the vertical frame elements 15 by its two rear corner areas.

[0069] Preferably, the integrated table 18 has a support section 27 on which the work table 40, which will be explained in more detail below, can be supported in a horizontal orientation with the fastening element 41 attached to the front of the work table 40 in order to assume a stable working position.

[0070] 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 17A, 17B. The support section 27 expediently comprises a groove, in particular a V-groove, into which the fastening element 41 can engage. The groove is preferably open at the top so that the fastening element 41 can engage into the groove from above. The groove expediently extends over the entire length of the horizontal frame element 17A, 17B.

[0071] The box-shaped containers 80 and the container mounting interface 6 will be explained in more detail below, in particular with reference to the Figure 1 . In the Figure 1 The transport vehicle 2 is shown with at least one attached box-shaped container 80 and an attached work table 40. This arrangement of transport vehicle 2, container 80, and work table 40 shall also be referred to as transport device 1.

[0072] 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. The container fastening interface 6 is expediently designed such that the container 80 can be attached to and / or detached from the container fastening interface 6 without the use of tools.

[0073] An example is the Figure 1 a vertical stack 90 comprising two box-shaped containers 80 stacked and coupled to one another, placed on the support surface 5 and fastened to the base part 4 by the container fastening interface 6.

[0074] 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, which is particularly foldable, is provided on the top of the container 80. The carrying handle 103 is purely optional and can also be omitted.

[0075] The container 80 has upper container coupling means 81 and lower container coupling means 82, which are particularly in the Figures 16, 17 and 18can 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] The containers 80 described above can, for example, be designed in accordance with the containers described in EP2315701B1.

[0082] The following section will discuss the possible configurations of the conveying device 1.

[0083] The conveying device 1 equipped with the elongated work table 40 can conveniently assume at least two different configurations: a transport configuration in which the work table 40 is arranged as shown in the Figure 1 shown in vertical orientation is attached to the transport vehicle 2 and a working configuration in which the work table as in the Figures 14 and 15 shown in horizontal orientation on the integrated table 18.

[0084] In the transport configuration, the work table 40 (and in particular also the box-shaped container 80) is firmly attached to the transport vehicle 2, so that the work table 40 (and the box-shaped container 80) are stably attached to the transport vehicle 2 even in a driving position in which the transport device 1 is tilted relative to the floor 30 and can be transported by the transport vehicle 2.

[0085] The elongated work table 40 can conveniently be completely removed from the transport vehicle, in particular without tools.

[0086] The elongated work table 40 can be fastened to the transport vehicle 2 in a vertical orientation in the rear area 7 without tools by means of the work table fastening interface 24 in order to assume a transport position in which the elongated work table 40 can be transported by the transport vehicle 2.

[0087] As in the Figure 1As can be seen, the work table 40 is aligned with its longitudinal axis vertically—i.e., in the z-direction—in the transport position. 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 upward from the lower part 4 in the transport position and preferably projects beyond the transport vehicle 2, in particular the integrated table 18 and / or the handle 12.

[0088] 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.

[0089] The Figures 14 and 15 show 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 14 and 15The 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 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.

[0090] In the working configuration, the fastening element 41 expediently engages with its fastening arrangement 48, in particular with the fastening projections 53, in the groove of the support section 27. In the working configuration, the work table 40 can expediently be removed from the transport vehicle 2 without tools.

[0091] 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 integrated table 18, 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.

[0092] Next, the work table mounting interface 24 will be discussed in more detail.

[0093] 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.

[0094] The work table mounting interface 24 comprises the first mounting device 20 and a second mounting device 21. The two mounting devices 20, 21 are, for example, in the Figure 8 shown

[0095] 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.

[0096] To remove the work table 40, it is necessary to loosen the second fastening device 21 and pivot the work table 40 away from the frame section 14 so that it assumes a tilted orientation relative to the vertical frame section 14. The work table 40 can then be removed from the transport vehicle 2 by a linear movement in the yz direction.

[0097] An exemplary embodiment of the second fastening device 21 will be discussed in detail below: The second fastening device 21 is arranged on the vertical frame section 14, for example in the upper region of the vertical frame section 14. The second fastening device 21 comprises a strap 23 with which the work table can be fixed horizontally to the vertical frame section 14 in the transport position. The strap 23 is fastened to two anchoring points, for example. The two anchoring points are located at the same height, for example. For example, the strap 23 is laid transversely around the work table 40 in the transport position. In this state, the strap 23 has a U-shaped course in an xy view. The strap 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 x-direction in the middle of the belt 23.

[0098] The handle 12 will be explained in more detail below: 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.

[0099] 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.

[0100] In the following, the work table 40 will be discussed in more detail, in particular with reference to the Figures 14 and 15 .

[0101] 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, preferably as metal profiles. A table top 44 is placed on the frame-shaped work table frame.

[0102] The work table 40 has a fold-out table leg assembly 46, which is U-shaped, for example. The vertical sections of the table leg assembly 46 (when unfolded) are also 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 one end of the work table 40.
