CONVEYOR DEVICE

Description

[0001] The invention relates to a transport device comprising a transport vehicle and a first box-shaped container, the transport vehicle comprising: a vehicle body having a lower section and a vertical frame section extending upwards from the lower section, the lower section having a base and a container fastening interface with which the first box-shaped container can be fastened to the lower section when placed on the base in such a way that the box-shaped container is fixed in all spatial directions, 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 section 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 only with 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.

[0006] 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.

[0007] DE 101 55 588 A1 describes a handcart with carrying devices.

[0008] US 2005 / 0077805 A1 concerns a modular storage cabinet.

[0009] An object of the invention is to improve the operability of the conveying device.

[0010] The object is achieved by a conveying device according to claim 1. The conveying vehicle has, above the container fastening interface, a pull-out arrangement arranged on the vertical frame section with a horizontally extendable container receiving element into which the first box-shaped container can be inserted from above.

[0011] The first box-shaped container can therefore be either attached to the container attachment interface or inserted into the container receiving element from above. Once inserted into the container receiving element, the box-shaped container can be extended horizontally together with the container receiving element and is easier to access. This improves the operability of the conveying device.

[0012] The container receiving element is expediently a drawer and / or is designed such that the box-shaped container can be inserted without tools and / or at least without being secured vertically. Inserting the container into the container receiving element can therefore be extremely simple and straightforward, in particular without additional user intervention (e.g., a fastening device) and / or without the need to modify the pull-out arrangement and / or the vehicle body for inserting the container.

[0013] Advantageous further training is the subject of the subclaims.

[0014] Exemplary details and embodiments are explained below with reference to the figures. Herein: Figure 1 shows a conveyor vehicle with an extension arrangement, Figure 2 shows a conveyor device with an extension arrangement and an inserted container, Figure 3 shows a conveyor vehicle with an extended extension arrangement, Figure 4 shows a conveyor device with a vertical stack of containers, Figure 5 shows an exploded view of components of a fastening mechanism, Figure 6 shows another exploded view of components of the fastening mechanism, Figure 7 shows a sectional view of the fastening mechanism, Figure 8 shows another sectional view of the fastening mechanism, Figure 9 shows another sectional view of the fastening mechanism, Figure 10 shows a rear view of the conveyor device with a work table attached, Figure 11 shows a detailed view of a fastening element of the work table, Figure 12 shows the conveyor device in a working configuration, Figure 13 shows a box-shaped container,Figure 14 shows a section through a container attached to the transport vehicle and Figure 15 shows a container placed on a parking area of the transport vehicle.

[0015] 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.

[0016] The Figure 2 shows a transport device 1 with a transport vehicle 2 and a first box-shaped container 80.

[0017] 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 which the first box-shaped container 80 can be fastened to the lower section 3 in a state placed on the base 5. A container 80 placed on the base 5 and fastened with the container fastening interface 6 is shown, for example, in the Figure 4 to see.

[0018] The transport vehicle 2 further comprises a handle 12 arranged on the vehicle body, with which the transport vehicle 2 can be placed in a tilting position, and 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 can be moved relative to the ground.

[0019] As in the Figure 1 As can be seen, the transport vehicle 2 comprises, above the container attachment interface 6, a pull-out arrangement 150 arranged on the vertical frame section 14 with a horizontally extendable container receiving element 152, into which the first box-shaped container 80 can be inserted from above. A container 80 inserted into the container receiving element 152 is shown in the Figure 2 to see.

[0020] Further exemplary details are explained below.

[0021] First, the basic structure of the transport vehicle 2: The transport vehicle 2 is in the Figure 1 shown on its own—i.e., without the box-shaped container 80. The transport vehicle 2 has a transverse front side 10, two longitudinal sides 9, and a transverse rear side 8.

[0022] The transport vehicle 2 can assume a stationary position in which it rests securely on the ground. In the stationary position, the lower section 3 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.

[0023] The transport vehicle 2 (without the handle 12) or the vehicle body consisting, for example, of the lower section 3, 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. The lower section 3 and the integrated table 18 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.

[0024] 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.

[0025] With the pull-out assembly 150, the transport vehicle 2 (without the handle 12) has a substantially E-shaped configuration in a yz-side view. The lower section 3, the pull-out assembly 150, and the integrated table 18 represent horizontal legs connected by the vertical frame section 14. The pull-out assembly 150 is arranged vertically between the lower section 3 and the integrated table 18.

[0026] If the (optional) integrated table 18 is not present, the transport vehicle 2 (without the handle 12) has, in a yz side view, essentially the shape of an upside-down F. The lower section 3 and the pull-out arrangement 150 represent horizontal legs that are connected by the vertical frame section 14.

[0027] 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 part 4 corresponds to the y-extension of the integrated table 18 and the y-extension of the extension assembly 150 (in the retracted position). 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.

[0028] The vertical frame section 14 is arranged in the rear area 7 of the transport vehicle 2. Conveniently, the integrated table 18 and / or the pull-out arrangement 150 is supported relative to the lower section 3 only by the vertical frame section 14 arranged in the rear area 7.

[0029] 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. The same applies to the removal and / or attachment of the pull-out arrangement 150. Conveniently, the integrated table 18 and / or the vertical frame section 14 cannot be removed from the vehicle body without tools.

[0030] The following describes the pull-out assembly 150 in more detail: The pull-out assembly 150 has a substantially cuboidal, flat basic shape and is horizontally oriented. The pull-out assembly 150 comprises a pull-out unit 151, which comprises a pull-out mechanism 153, in particular a telescopic pull-out, and the container receiving element 152 fastened to the pull-out mechanism 153. The pull-out mechanism 153 is, for example, Figure 3 The pull-out assembly 150 further comprises a support assembly 155 to which the pull-out mechanism 153 is attached. The container receiving element 152 is horizontally displaceable relative to the support assembly 155 via the pull-out mechanism 153, particularly in the y-direction. The support assembly 155 is fixed in the horizontal direction relative to the vertical frame section 14 or the transport vehicle 2.

[0031] The container receiving element 152 can be moved relative to the support arrangement 155, in particular relative to the vertical frame section 14, into a retracted and an extended position, in particular by a movement in the y-direction. Figure 1 shows the container receiving element 152 in a retracted position and the Figure 3 shows the container receiving element 152 in an extended position. For example, the container receiving element 152 has a handle 210 on its front side with which it can be pulled out forward.

[0032] In the retracted position, the container receiving element 152 expediently occupies the same xy-range as the lower section 3 and / or the integrated table 18. In the extended position, the container receiving element 152 expediently also occupies an xy-range that lies in front of the lower section 3 and / or the integrated table 18 in the y-direction. In the extended position, the container receiving element 152 is expediently located with at least half or three-quarters of its y-extension in the y-direction in front of the lower section 3 and / or the integrated table 18.

[0033] By way of example, the container receiving element 152 is designed as a drawer. The container receiving element 152 is open at the top so that the box-shaped container 80 can be inserted into the container receiving element 152 from above. Preferably, no user actuation of any fastening device is required to insert and / or remove the box-shaped container 80 into / from the container receiving element 152. The box-shaped container 80 is expediently simply placed on the receiving base of the container receiving element 152 without the box-shaped container 80 being fastened to the container receiving element 152. When received by the container receiving element 152, the box-shaped container 80 is thus not fastened or loose, particularly in the vertical direction.

[0034] The container receiving element 152 has the receiving base on which the box-shaped container 80 can be placed. Preferably, four peripheral walls extend upward from the receiving base, which, together with the receiving base, define a cuboid, flat receiving volume. The four peripheral walls expediently stabilize the box-shaped container 80 laterally in the inserted state. The z-extension of the peripheral walls is expediently less than half or less than one-third of the z-extension of the box-shaped container 80.

[0035] The box-shaped container 80 expediently has feet on its underside, which are arranged in particular in the corner regions of the box-shaped container 80. One or more recesses for receiving the feet are expediently provided in the receiving base of the container receiving element 152. For example, two elongated recesses extending in the y-direction are provided in the receiving base, each of which is located in the edge region of the receiving base in the x-direction.

[0036] Preferably, the first box-shaped container 80 can be inserted into and / or removed from the container receiving element 152 from above in a retracted state, expediently in every retracted state, and in an extended state, expediently in every extended state, of the container receiving element 152. Expediently, the first box-shaped container 80 is accessible in every retracted and / or extended state of the container receiving element 152, so that, for example, the lid 102 of the container 80 can be opened. The pull-out arrangement 150, in particular the support arrangement 155, is designed to be open at the top, so that the container receiving element 152 and in particular a container 80 inserted into the container receiving element 152 remains accessible even in the retracted state of the container receiving element 152.

[0037] The support arrangement 155 comprises, by way of example, two support arms 154 extending horizontally forward from the vertical frame section 14, on which the container receiving element 152 is displaceably mounted by means of the extension mechanism 153. The support arms 154 extend parallel to one another. The y-extension of the support arms 154 is expediently substantially equal to the y-extension of the container receiving element 152 in the retracted state.

[0038] As explained in more detail below, the vertical frame section 14 has two mutually parallel, vertically upwardly extending vertical frame elements 15. A support arm 154 is conveniently arranged on each of these vertical frame elements 15.

[0039] As in the Figure 3As can be seen, the two support arms 154 are connected to each other by two intersecting, elongated stabilizing elements 156. The stabilizing elements 156 preferably extend below the container receiving element 152 and expediently span a horizontal plane.

[0040] According to an embodiment not shown in the figures, the transport vehicle 2 comprises at least two pull-out assemblies arranged distributed in the vertical direction on the vertical frame section 14. The pull-out assemblies are expediently designed identically to the discussed pull-out assembly 150 and are preferably arranged one above the other on the vertical frame section 14.

[0041] The following will deal with the fastening mechanism 170, which is expediently part of the pull-out arrangement 150. The fastening mechanism 170 is (from the outside) e.g. in the Figure 1can be seen. A corresponding fastening mechanism 170 is expediently arranged on each of the two outwardly directed longitudinal sides of the pull-out arrangement 150, for example on each outwardly directed longitudinal side of the support arms 154.

[0042] The fastening mechanism 170 allows the pull-out assembly 150 to be fixed vertically to the vertical frame section 14 without the need for tools. The fastening mechanism 170 is expediently designed to fix the pull-out assembly 150 vertically by clamping it to the vertical frame section 14. The vertical fixation preferably occurs exclusively via frictional engagement.

[0043] The fastening mechanism 170 is expediently designed such that the vertical fixation can be released by user actuation. Once the vertical fixation is released, the pull-out assembly 150, when attached to the vertical frame section 14, can be positioned vertically steplessly relative to the vertical frame section 14. The pull-out assembly 150 can be moved steplessly—i.e., in particular continuously—on the vertical frame section 14, in particular the two vertical frame elements 15, as if on rails (in the vertical direction) and can be vertically fixed at the desired location by clamping it with the fastening mechanism 170. Preferably, stepless positioning is possible over the entire z-extension of the vertical frame section 14.

[0044] Furthermore, the pull-out assembly 150 can expediently be removed and / or attached to the vertical frame section 14 without tools via the fastening mechanism 170. Preferably, the pull-out assembly 150 is fastened to the vertical frame section 14 in the horizontal direction, in particular in the y-direction and / or x-direction, by means of a positive fit. This fastening, in particular this positive fit, can expediently be released by actuating the fastening mechanism 170.

[0045] The fastening mechanism 170 has a first operating device 171 for tool-free removal / attachment of the pull-out assembly 150 from the vertical frame section 14 and a second operating device 172 for tool-free vertical fixation of the pull-out assembly 150 to the vertical frame section 14. The first operating device 171 can be actuated in particular via a first operating element 173, and the second operating device 172 via a second operating element 174. The first operating element 173 and / or the second operating element 174 are preferably designed in the shape of a tab. The first operating element 173 and / or the second operating element 174 are expediently pivotably mounted and can preferably be pivoted to actuate the respective associated operating device 171, 172. The second operating element 174 is expediently pivotably mounted on the first operating element 173.Preferably, a corresponding first operating element 173 and a corresponding second operating element 174 are provided on each support arm 154.

[0046] As in the Figures 7 and 8 As shown, the first operating element 173 comprises a fastening section 181, which can be brought into engagement with a contact surface 191 present on the vertical frame section 14 by pivoting the first operating element 173 in order to attach the pull-out assembly 150 to the vertical frame section 14. Exemplary details in this regard will be explained below.

[0047] The first operating element 173 is coupled to the second operating element 174 via an eccentric structure 187, so that when the second operating element 174 is pivoted, the fastening section 181 resting against the contact surface 191 is attracted toward the contact surface 191, so that the pull-out assembly 150 is clamped to the vertical frame section 14 and thereby fixed vertically. Exemplary details in this regard will be explained below.

[0048] The fastening mechanism 170 has a third control element 178, via which the strength of the vertical fixation of the pull-out assembly 150 to the vertical frame section 14 can be adjusted. The third control element 178 expediently comprises a knurled nut 178.

[0049] In the following, with reference to the Figures 5 to 9 an exemplary design of the fastening mechanism 170 will be discussed.

[0050] The Figure 5shows an exploded view of components of a fastening mechanism 170 arranged on a left side of the pull-out assembly 150 and the Figure 6 shows an exploded view of components of a fastening mechanism arranged on a right side of the drawer assembly 150. The two Figures 5 , 6 The fastening mechanisms shown are expediently identical and / or mirror-symmetrical to a yz-plane, so that both fastening mechanisms will be discussed together below.

[0051] In the Figure 5 In particular, an elongated support arm body 180 is shown, which together with the fastening mechanism 170 forms a support arm 154. The elongated support arm body 180 is expediently manufactured as an injection-molded part.

[0052] In the Figure 6The outside of a support arm body 180 is visible. The support arm body 180 has a recess at its end proximal to the vertical frame section 14 for receiving the fastening mechanism 170.

[0053] The fastening mechanism 170 comprises the first operating element 173, which is designed as a tab. As shown in the Figure 5 As can be seen, the first control element 173 has an elongated base section extending in the y-direction, from which two spaced-apart coupling sections 183, 189 protrude in the x-direction. Each coupling section 183, 189 has a hole.

[0054] The Figure 9shows an xy section through a support arm 154 having a fastening mechanism 170 in the assembled state. A first spring 176, a bolt 177, and the knurled nut 178 are arranged between the two coupling sections 183, 189, from the first coupling section 183 to the second coupling section 189. A screw 175 extends through the first coupling section 183, the first spring 176, the bolt 177, the knurled nut 178, and the second coupling section 189. A thread is provided in the knurled nut 178, into which the screw 175 is screwed. The bolt 177 extends transversely to the screw 175.

[0055] In the Figure 5Also shown is the second operating element 174, which is designed, for example, in the shape of a tab. The second operating element 174 has a base section extending in the y-direction, from which a coupling structure 187 protrudes at a distal end, which is designed, in particular, as an eccentric structure. The coupling structure 187 comprises, for example, two essentially cylindrical structural sections that are arranged coaxially to one another and have pivot bearing sections 185 on the outside, which are designed, for example, as circular elevations. Bolt-receiving sections 184 into which the bolt 177 can be inserted are arranged on the inside of the structural sections. Expediently, the bolt 177 is engaged in the bolt-receiving sections 184 in the assembled state. Preferably, the second operating element 174 is pivotally mounted on the first operating element 173 via the bolt 177 and the screw 175.

[0056] With the pivot bearing sections 185, the second operating element 174 (with the attached first operating element 173 and the aforementioned components 175 to 178) can be inserted into the recess provided on the support arm body 180, in particular on pivot bearing receiving sections 188. A second spring 179 is expediently arranged between an actuating section 182 arranged at the distal end of the first operating element 173 and the support arm body 180.

[0057] The Figure 9 shows how the pivot bearing sections 185 are inserted into the pivot bearing receiving sections 188. In this state, the second operating element 174 is mounted on the extension assembly 150, in particular the support arm body 180, so as to be pivotable about a rotation axis defined by the pivot bearing sections 185 and extending in the z-direction.

[0058] With reference to the Figures 7 and 8The following explains the functionality of the exemplary fastening mechanism 170. The Figures 7 and 8 show xy sections of the fastening mechanism 170. Shown is the fastening mechanism 170 arranged on the right longitudinal side of the pull-out arrangement 150. Expediently, the fastening mechanism 170 arranged on the left longitudinal side of the pull-out arrangement 150 (if present) is actuated accordingly.

[0059] Conveniently, the fastening mechanism 170 can be placed in three different states: a first state in which the first operating device 171 and the second operating device 172 are not actuated, a second state in which the first operating device 171 is actuated and the second operating device 172 is not actuated, and a third state in which the first operating device 171 is actuated and the second operating device 172 is not actuated. Conveniently, the second operating device 172 covers the actuating section 182 of the first operating device 171 in the actuated position, so that the first operating device 171 cannot be actuated in this state.

[0060] The first operating device 171 is expediently actuated by pressing the actuating section 182 inwards in the x-direction, for example by a user's finger. The actuating section 182 is expediently located on the outside of the first operating element 173, at the distal end facing away from the fastening section 181. By actuating the actuating section 182, the first operating element 173 is pivoted about a rotational axis running parallel to the z-direction. By releasing the actuating section 182, the first operating element 173 is automatically pivoted back due to the second spring 179 and assumes its unactuated position. In Figure 7, the first operating element 173 is in the actuated position and in the Figure 8 shown in the unactuated position.

[0061] In the unactuated position of the second operating device 172, the second operating element 174 is pivoted about a rotational axis parallel to the z-direction and projects outwards, in particular, in an xy-direction. This position shall be referred to as the unactuated position and is, for example, in the Figure 7 shown. The outwardly projecting portion shall also be referred to as the actuating portion 186. By user actuation, the second operating element 174 can be pivoted about its axis of rotation, so that it rests against the outer longitudinal side of the pull-out arrangement 150, in particular the support arm 154, and assumes the actuated position, which, for example, in the Figure 8This position of the second operating element 174 is stable, so that further user actuation of the actuating section 186 is required to return the second operating element 174 to the unactuated position. Conveniently, the operating element 174 passes through a dead center between the actuated and unactuated positions.

[0062] As in the Figure 7As shown, the pull-out arrangement 150, in particular the support arm body 180, rests with a first, in particular transverse, contact surface 194 and a second, in particular longitudinal, contact surface 195 against a corresponding first, in particular transverse, contact surface 192 of the vertical frame element 15 and a second, in particular longitudinal, contact surface 193 of the vertical frame element 15. The contact surfaces 192, 193 are expediently located on the inside of the vertical frame element 15. On the outside, the vertical frame element 15 expediently has the contact surface 191, which should also be referred to as the third contact surface 191. The third contact surface 191 is, by way of example, part of a groove 190, in particular a U-groove, which is preferably arranged on the outside of the vertical frame element 15.

[0063] The aforementioned contact surfaces 191, 192, 193 expediently extend over at least half, preferably over the entire z-extension of the vertical frame section 14.

[0064] The first operating element 173 has the exemplary hook-shaped fastening section 181 which, as shown in the Figure 8 As can be seen, in the unactuated state of the first operating device 171, it engages with the third contact surface 191 (by engaging in the groove 190) and thus the pull-out arrangement 150 is attached to the vertical frame section 14 by form fit. As shown in the Figure 7 As can be seen, the engagement of the fastening section 181 can be released by actuating the first operating element 173, so that the pull-out arrangement 150 is no longer fastened to the vertical frame section 14, in particular in the y-direction, and can be completely removed from the vertical frame section 14 in this direction.

[0065] To reattach the pull-out assembly 150 to the vertical frame section 14, the first operating element 173 must be actuated again so that the fastening section 181 can snap into the vertical frame element 15.

[0066] If the pull-out assembly 150 is attached to or suspended in the vertical frame section 14, it is expedient to actuate the second operating element 174 in order to fix the pull-out assembly 150 vertically. Due to the eccentric structure 187, pivoting the second operating element 174 pulls the first operating element 173 with its fastening section 181 against the third contact surface 191, so that the vertical frame section 15 is clamped between the fastening section 181 and the first contact surface 194. The pull-out assembly 150 is thus clamped to the vertical frame section 14 and can no longer be moved in the z-direction on the vertical frame section 14. The strength orThe clamping force of the fixation can be adjusted via a third operating element, in particular the knurled nut 178, via which the first operating element 173 - and thus the fastening section 181 - can be positioned relative to the support arm body 180 - and thus to the contact surface 194.

[0067] As in the Figures 1 and 2 As can be seen, fixing elements 157 can also be arranged on the vertical frame section 14 above the pull-out arrangement 150, which serve to horizontally stabilize an inserted container 80. The fixing elements 157 are, in particular, vertically displaceable and / or have corner-shaped recesses for receiving the rear corner areas of the container 80.

[0068] In the following, the container fastening interface 6 present in the lower section 3 will be discussed in more detail.

[0069] The container fastening interface 6 serves to fasten the box-shaped container 80 to the lower section 3 of the transport vehicle 2 such 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 need for tools.

[0070] By way of example, the container fastening interface 6 comprises a movable coupling element 91 that can be selectively moved into a locking position or a release position by user actuation. In the locking position, the coupling element 91 engages with a first non-movable coupling structure arranged on the box-shaped container 80. In the release 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 section 4.

[0071] The movable coupling element 91 is exemplified as a rotary latch, in particular as a T-shaped rotary latch. Preferably, the movable coupling element 91 is a rigid body movably attached to the lower section 3. 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.

[0072] The movable coupling element 91 is exemplarily mounted on the front side 10 of the lower section 3 and is preferably rotatably mounted, in particular about a y-axis of rotation. The movable coupling element 91 is expediently arranged in a recess on the front side 10.

[0073] The container fastening interface 6 preferably further comprises a non-movable coupling structure 92, which is exemplified as recesses arranged in the support surface 5. The non-movable coupling structure 92 comprises, for example, two elongated recesses arranged in the region of the longitudinal sides 9, which extend in the y-direction. The non-movable coupling structure 92 can be brought into engagement with the lower container coupling means 82, which will be explained below.

[0074] 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.

[0075] The box-shaped container 80 will be explained in more detail below, in particular with reference to the Figure 4For reasons of better visibility, the Figure 4 the pull-out arrangement 150 is not shown.

[0076] 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, in particular to its rear side. Preferably, the lower part 101 and the lid 102 have the same horizontal outer contour. A carrying handle 103, which is in particular foldable, is provided on the upper side of the container 80. The carrying handle 103 is purely optional and can also be omitted.

[0077] The container 80 has upper container coupling means 81 and lower container coupling means 82, which are particularly in the Figures 13 to 15can 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.

[0078] 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.

[0079] 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.

[0080] The Figure 14 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.

[0081] 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.

[0082] 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.

[0083] The containers 80 described above can, for example, be designed in accordance with the containers described in EP2315701B1.

[0084] 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.

[0085] An example is the Figure 4a vertical stack 90 comprising two box-shaped containers 80 stacked and coupled to one another is placed on the support surface 5 and fastened to the lower section 3 by the container fastening interface 6. The stack 90 is expediently fastened exclusively to the lower section 3, in particular exclusively to the lower part 4.

[0086] The one in the Figure 4 The lower container 80 placed on the parking area 5 should be referred to as the first container 80 and the upper container 80 as the second container 80. If the transport vehicle 2 in the Figure 4 the one discussed above, exemplified in the Figures 1 to 3If the pull-out arrangement 150 shown is present on the vertical frame section 14, the second container 80, in a state removed from the first container 80, can optionally be placed on the first container 80 and fastened thereto or inserted into the container receiving element 152 of the pull-out arrangement 150.

[0087] The lower section 3 will be discussed in more detail below: The lower section 3 expediently comprises a lower part 4. The lower part 4 expediently forms the lower section 3. The lower part 4 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.

[0088] The vertical frame section 14 extends upward from the top of the lower part 4. The storage area 5 is located on the top of the lower part 4. Furthermore, the container attachment interface 6 is located on the lower part 4, in particular exclusively on the lower part 4.

[0089] 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.

[0090] On the lower part 4, there is preferably 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 fastening interface 137 is shown by way of example in the Figure 3 shown.

[0091] The pull-out unit 151 can expediently also be provided without the support arrangement 155 and / or in addition to the pull-out arrangement 150 and can be attached directly to the pull-out attachment interface 137, so that an extendable 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.

[0092] The pull-out fastening interface 137 is arranged, for example, on the inner sides of the legs of a U-shaped elevation of the lower part 4. The U-shaped elevation is expediently configured such that the pull-out unit 151 fits into the space provided between the legs of the U-shaped elevation. 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 attached to the lower part 4 via screw connections.

[0093] 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.

[0094] 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.

[0095] The vertical frame elements 15 are designed as profiles, in particular as metal profiles.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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 a fastening element 41 attached to the front of the work table 40 in order to assume a stable working position.

[0100] The support section 27 is, for example, in the Figure 4and 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 the groove from above. The groove expediently extends over the entire length of the horizontal frame element 17A, 17B.

[0101] In the following, possible configurations of the conveying device 1 will be discussed.

[0102] The conveying device 1 equipped with the elongated work table 40 explained below can conveniently assume at least two different configurations: a transport configuration in which the work table 40 is arranged as shown in the Figure 4shown in vertical orientation is attached to the transport vehicle 2 and a working configuration in which the work table as in the Figure 12 shown in horizontal orientation on the integrated table 18.

[0103] In the transport configuration, the work table 40 (and / or the box-shaped container 80) is firmly attached to the transport vehicle 2, so that the work table 40 (and / or the box-shaped container 80) are stably attached to the transport vehicle 2 even in a travel position in which the transport device 1 is tilted relative to the floor 30 and can be transported by the transport vehicle 2. All containers 80 are attached to the container attachment interface 6 in the transport configuration (conveniently as a vertical stack 90).

[0104] The elongated work table 40 can conveniently be completely removed from the transport vehicle, in particular without tools.

[0105] 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 a work table fastening interface 24 explained below in order to assume a transport position in which the elongated work table 40 can be transported by the transport vehicle 2.

[0106] 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.

[0107] 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.

[0108] In the transport configuration, the (in the Figure 4 not shown) pull-out assembly 150 is attached to the vertical frame section 14. Conveniently, no container 80 is inserted into the container receiving element 152.

[0109] The Figure 12shows 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 Figure 12 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 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.

[0110] Conveniently, the fastening element 41, explained below, engages in the working configuration with its fastening arrangement 48, in particular with the fastening projections 53, in the groove of the support section 27. Conveniently, the work table 40 can be removed from the transport vehicle 2 without tools in the working configuration.

[0111] 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.

[0112] In the working configuration, the (in the Figure 12not shown) pull-out assembly 150 is attached to the vertical frame section 14. Conveniently, a container 80 is detached from the container mounting interface 6 or a vertical stack 90 and inserted into the container receiving element 152.

[0113] Next, the work table mounting interface 24 will be discussed in more detail.

[0114] The worktable attachment interface 24 serves to attach the worktable 40 to the transport vehicle 2 in such a way that the worktable 40 can be stably transported by the transport vehicle 2. Preferably, the worktable attachment interface 24 is configured such that, when attached, the worktable 40 is fixed in all spatial directions relative to the transport vehicle 2. It should be noted that the worktable 40 and / or the worktable attachment interface 24 are purely optional features.

[0115] 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 10 shown.

[0116] 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.

[0117] 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.

[0118] 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 10 and 11 shown.

[0119] 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.

[0120] 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.

[0121] The Figure 11 shows the Figure 10 area marked "Y" in detail. For better visibility, the work table 40 is Figures 10 and 11shown 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.

[0122] As in the Figure 11 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 engaged 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. The fastening structure 29 comprises, for example, a fastening surface (not shown in the figures) behind which the fastening arrangement 48 engages.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] In the following, the work table 40 will be discussed in more detail, in particular with reference to the Figure 12 .

[0127] 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.
