TRANSPORT VEHICLE AND TRANSPORT DEVICE

Description

[0001] The invention relates to a transport device comprising a transport vehicle comprising: a vehicle body having a lower portion and a vertical frame portion extending upwards from the lower portion, the lower portion having a base and a container attachment interface with which a box-shaped container placed on the base can be attached to the lower portion without changing the vertical frame portion, 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 portion with which the transport vehicle can be supported against a ground in the tilting position and can be moved relative to the ground.

[0002] 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.

[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.Conveniently, the stack is secured to the transport vehicle with only the lowest box-shaped 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 or removed. The box-shaped container can conveniently be removed from and / or attached to the transport vehicle without the need for tools.

[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.

[0011] An object of the invention is to equip the transport vehicle with an additional function while maintaining its compact and simple design.

[0012] The object is achieved by a conveying device according to claim 1. The conveying vehicle comprises a horizontally oriented, integrated table which is arranged at the upper end of the vertical frame section and forms the upper end of the vehicle body.

[0013] This allows the transport vehicle to be used not only for transporting box-shaped containers but also as a work table. The integrated table forms the upper end of the vehicle body, allowing the compact and simple design of the transport vehicle to be maintained.

[0014] The conveying device further 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 in a vertical orientation in a rear region of the conveying vehicle without tools in order to assume a transport position in which the elongated work table can be conveyed by the conveying vehicle, wherein the integrated table has a support section on which the work table can be supported in a horizontal orientation with a fastening element attached to the front of the work table in order to assume a stable working position.

[0015] Advantageous further training is the subject of the subclaims.

[0016] Exemplary details and embodiments are explained below with reference to the figures. Herein: Figure 1 shows a perspective view of a transport vehicle, Figure 2 shows a further perspective view of the transport vehicle, Figure 3 shows a perspective view of a transport device in a transport configuration, Figure 4 shows a rear view of the transport vehicle, Figure 5 shows a perspective rear view of the transport device, Figure 6 shows a detailed view of a first fastening device of the transport vehicle, Figure 7 shows a perspective view of the transport device in a working configuration, Figure 8 shows a further perspective view of the transport device in the working configuration, Figure 9 shows a perspective view of a box-shaped container, Figure 10 shows a vertical section through a container attached to a container fastening interface and Figure 11 shows a container placed on a parking space of the transport vehicle.

[0017] 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.

[0018] The Figures 1 and 2show a transport vehicle 2. The transport vehicle 2 comprises a vehicle body with a lower section 3 and a vertical frame section 14 extending upwards from the lower section 3. The lower section 3 has a base 5 and a container fastening interface 6. With the container fastening interface, a box-shaped container 80 placed on the base 5 can be fastened to the lower section 3. Such a container 80 is shown as an example in the Figure 3 shown. No modification, in particular no conversion, of the vertical frame section 14 is required to attach or remove the box-shaped container 80.

[0019] The transport vehicle 2 further comprises a handle 12 arranged on the vehicle body, in particular on the vertical frame section 14, 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 section 3, with which the transport vehicle 2 can be supported against a ground in the tilting position and moved relative to the ground.

[0020] The transport vehicle further comprises a horizontally oriented, integrated table 18 which is arranged at the upper end of the vertical frame section 14 and forms the upper end of the vehicle body.

[0021] Further exemplary details are explained below.

[0022] First, the basic structure of the transport vehicle 2: 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-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. 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 when stationary. A wheel 11 is arranged on each of the longitudinal sides 9 of the lower part 4, specifically in the rear area 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.

[0023] 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. In the stationary position, the transport vehicle 2 expediently rests only on the support feet 39 and, in particular, not on the wheels 11. 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 sack barrow and can also be described as having a sack barrow design.

[0024] The vehicle body consisting, for example, of the lower section 3, the vertical frame section 14 and the 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 section 3 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 section 3 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 section 3 in the y-direction and greater than the extension of the integrated table 18 in the y-direction. The y-extension of the lower section 3 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 section 3 only by the vertical frame section 14 arranged in the rear region 7. Between the integrated table 18 and the lower section 3, 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 section 3, 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 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 section 3 and running parallel to one another. Preferably, the vertical frame section 14 consists of the two frame elements 15.

[0030] 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.

[0031] The vertical frame elements 15 are designed as profiles, in particular as metal profiles.

[0032] 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. Conveniently, the integrated table 18 represents the vertically highest point of the transport vehicle 2 without the handle 12.

[0033] The integrated table 18 comprises a horizontal frame section with at least one horizontal frame element 17A. The horizontal frame element 17A is arranged at the upper end of the vertical frame section 14. The integrated table 18 further comprises a table top 19 arranged, in particular placed, on the horizontal frame element 17A.

[0034] The table top 19 is exemplary rectangular. On its upper side, the table top 19 has, for example, a hole pattern 120 with regularly spaced holes. The holes serve, for example, for attaching clamping elements (not shown in the figures) with which, for example, a workpiece can be secured to the integrated table. As an example, the table top 19 also has, on its upper side, recesses 121 for receiving feet of a container (not shown in the figures). The recesses are exemplary rectangular and arranged in the corner regions of the table top 19. Furthermore, the table top 19 has, for example, a groove 122 running across the upper side of the table top 19. The groove is preferably designed as a V-groove and is used in particular for securing workpieces. The V-groove expediently extends over the entire x-extension of the table top 19.

[0035] As mentioned above, the integrated table 18 comprises a horizontal frame section with at least one elongated horizontal frame element 17A on which the table top 19 is arranged. The horizontal frame element 17A extends from the upper end of one vertical frame element 15 to the upper end of the other vertical frame element 15.

[0036] The integrated table 18, in particular the horizontal frame section, exemplarily the horizontal frame element 17A, thus serves as a stiffening element for the vertical frame section 17A. Advantageously, no further stiffening elements are present between the two vertical frame elements 15 between the integrated table 18 and the lower part 4.

[0037] By way of example, the horizontal frame section comprises, in addition to the aforementioned horizontal frame element 17A, three further elongated horizontal frame elements 17A, 17B.

[0038] The integrated table 18 thus 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 the 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 lower section 3. The integrated table 18 expediently has a cuboid, in particular flat, basic shape.

[0039] As in the Figure 2As can be seen, the two horizontal frame elements 17A are aligned parallel to the x-direction and the two horizontal frame elements 17B are aligned parallel to the y-direction. The frame element 17A 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 17B aligned parallel to the y-direction extend forward in the y-direction from the upper ends of the vertical frame elements 15.

[0040] 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.

[0041] The horizontal frame section has, for example, four corner elements arranged at the corners of the horizontal frame section and each connecting a horizontal frame element 17A to a horizontal frame element 17B. For example, each corner element has two openings aligned at 90 degrees to each other. One end of a horizontal frame element 17A is inserted into one of the openings, and one end of a horizontal frame element 17B is inserted into the other opening. The corner elements are preferably made of plastic.

[0042] As in the Figure 2As can be seen, the horizontal frame elements 17A, 17B are further fastened to one another via angle connectors 124A, 124B. The angle connectors 124A, 124B are arranged on the inward-facing sides of the horizontal frame elements 17A, 17B. The angle connectors 124A and 124B each connect a horizontal frame element 17A to a horizontal frame element 17B. The angle connectors 124B expediently also serve to fasten the horizontal frame section to the vertical frame section 14. Expediently, the angle connectors 124A are designed as two-leg, L-shaped angle connectors and preferably each connect exclusively a horizontal frame element 17A to a horizontal frame element 17B. The angle connectors 124B are preferably designed as three-leg angle connectors and each connect a horizontal frame element 17A and a horizontal frame element 17B to a vertical frame element 15.

[0043] Preferably, the integrated table 18 has a support section 27 on which a work table 40, which will be explained below, can be supported in a horizontal orientation with a fastening element 41 attached to the front of the work table 40 in order to assume a stable working position.

[0044] The support section 27 is, for example, in the Figure 1 and 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.

[0045] 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 3 . In the Figure 3 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.

[0046] 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.

[0047] An example is the Figure 3 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 lower section 3 by the container fastening interface 6.

[0048] 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.

[0049] 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.

[0050] The container attachment interface 6 preferably further comprises a non-movable coupling structure 92, which, by way of 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, which will be explained below.

[0051] 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. Now to container 80:

[0052] 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 fold-out carrying handle 103 is provided on the upper side of the container 80.

[0053] The container 80 has upper container coupling means 81 and lower container coupling means 82, which are particularly in the Figures 9 to 11are shown. 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.

[0054] 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 is arranged, in particular, on the front side of the container 80.

[0055] The lower container coupling means 82 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.

[0056] The Figure 10 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] The containers 80 described above can, for example, be designed in accordance with the containers described in EP2315701B1.

[0061] The following section will discuss the possible configurations of the conveying device 1.

[0062] 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 3 shown in vertical orientation is attached to the transport vehicle 2 and a working configuration in which the work table as in the Figures 7 and 8 shown in horizontal orientation on the integrated table 18.

[0063] 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 and can be transported by the transport vehicle 2 even in a driving position in which the transport device 1 is tilted relative to the floor 30.

[0064] The elongated work table 40 can conveniently be completely removed from the transport vehicle, in particular without tools.

[0065] To attach the work table 40 to the transport vehicle 2, the transport vehicle 2 has a work table attachment interface 24 with which the elongated work table 40 can be attached to the transport vehicle 2 in a vertical orientation in the rear area 7 without tools in order to assume a transport position in which the elongated work table 40 can be transported by the transport vehicle 2.

[0066] As in the Figure 3As can be seen, in the transport position, the work table 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 integrated table 18 and / or the handle 12.

[0067] 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.

[0068] The Figures 7 and 8 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 7 and 8The 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 ends by the transport vehicle 2, in particular by the integrated table 18.

[0069] In the Figures 7 and 8The 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.

[0070] 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.

[0071] 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.

[0072] Next, the work table mounting interface 24 will be discussed in more detail, particularly with reference to the Figures 4 to 6 .

[0073] 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.

[0074] 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 4 shown

[0075] 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.

[0076] 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.

[0077] 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.

[0078] The Figure 6 shows the Figure 5 area marked "Y" in detail. For better visibility, the work table 40 is Figures 5 and 6 shown in a position in which the fastening element 41 is not inserted into the slot 22.

[0079] In the Figure 6In 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 an angled upper side 25.

[0080] In the Figure 6 The 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.

[0081] 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 a basic L-shaped configuration. 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 vertically extending first leg and a second leg extending obliquely downward from the first leg in a yz-direction. 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.

[0082] 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 plastic.

[0083] The fastening structure 29 is accessible via the slot 22.

[0086] 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.

[0087] In the following, the work table 40 will be discussed in more detail, in particular with reference to the Figures 7 and 8 .

[0088] 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.

[0089] 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.

[0090] The work table 40 has fixing elements 45 with which the table leg assembly 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.

[0091] 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 17A, 17B of the integrated table 18 comprise the same profiles or profiles of the same type, preferably of the same cross-section (but expediently of different lengths).

[0092] Preferably, the work table frame elements 42, 43 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.

[0093] The table top 44 conveniently has a hole pattern. The hole patterns of the two table tops 44, 19 conveniently have the same hole spacing.

[0094] In the following, a method will be described how the conveying device 1 is changed from the transport configuration (cf. Fig. 3 ) into the working configuration (see Fig. 7 ) can be moved.

[0095] 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.

[0096] 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.

[0097] 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.
