Description

The invention relates to a transport device, in particular a transport container for formwork elements, which can be transferred between an unfolded position and a folded position, with a pivotable frame which has two essentially parallel first side parts and two essentially parallel second side parts, each of which has joints with are pivotably connected to the first side parts, so that the transport device can be transferred between the unfolded position and the folded position by parallel pivoting of the first with respect to the second side parts, during which the first and second side parts remain arranged essentially parallel to one another.

Furthermore, the invention relates to different types of use of the transport device.

Formwork elements, such as formwork panels and formwork props, can be transported to construction sites using crates and containers. However, a disadvantage of crates and containers is that they unnecessarily take up a lot of space when they are no longer needed after transport.

Cardboard boxes are known from the distant field of the packaging industry, which can be folded together by folding up individual base parts and subsequent parallel pivoting of the cardboard walls. Due to the parallel pivoting, the cardboard boxes can be folded together quickly and, above all, intuitively thanks to the guided mechanics. However, due to the high weight of formwork elements, cardboard boxes are not suitable for transporting them. Another disadvantage of cardboard boxes is that they can be destroyed by moisture and humidity.

Out of DE 20 2011 051 070 U1 a mounting frame is known which has grids as side walls and can be placed on a pallet. The mounting frame can be collapsed by folding the side walls together, but not by parallel pivoting of the side walls.

In DD 271 091 A1 a collapsible stake pallet for transporting bar, profile and pipe material is shown. The stanchion pallet has stanchions and longitudinal bars that can be divided in the middle and folded together with hinges. The longitudinal beams are also connected to the stanchions via joints so that they can be folded. In order to fold up the pallet of stakes, the longitudinal beams must be pivoted upwards. This means that the stanchion range of the DD 271 091 A1 do not bring it into a folded state by parallel pivoting of side parts.

From the DE 20 2010 017 755 U1 a lattice box is known which can be broken down into individual parts for storage.

In the light of these statements, the object of the present invention is to partially or completely alleviate the disadvantages of the prior art. The object of the present invention is preferably to provide a stable, structurally simple and easy-to-handle transport device with which heavy objects such as formwork elements can be transported and which can be quickly and easily placed in a space-saving position after transport.

This object is solved by a transport device having the features of claim 1. Preferred embodiments are specified in the dependent claims. A kit with transport devices is described in claim 17. The transport device can be used according to claims 18, 19 and 20.

According to the invention, in a transport device of the type mentioned at the outset, a fixing element is provided which can be fastened to at least two side parts when the transport device is in the unfolded position, so that the frame is locked and the parallel pivoting of the first side parts relative to the second side parts is blocked. The stability of the transport device in the unfolded state is advantageously improved overall by the fixing element and unintentional transfer of the transport device into the folded state during transport is prevented. In order to fix the transport device in the unfolded position, the fixing element can be fastened to at least two side parts—for example, to the two first side parts, to the two second side parts or to a first and a second side part. Fastening the fixing element prevents all side parts from pivoting in parallel. Fastenable preferably means that the fixing element can be connected to the side parts in such a way that the parallel pivoting of the first side parts relative to the second side parts is blocked and the fixing element is held on the frame. This can be done, for example, by blocking a degree of freedom of one or more joints between the side parts. In the unfolded position, for example, the fixing element can be fastened to the frame non-parallel to all of the side parts, so that parallel pivoting is no longer possible. The Fixele ment can be releasably attached to the frame, in particular releasably and reversibly without tools. In one embodiment, the fixing element can also be used to fix the transport device in the folded position, so that the frame is locked and the parallel pivoting of the first relative to the second side parts is blocked. Several fixing elements can also be provided. A fixing element can be formed, for example, by a strut, an angle element or a surface element, for example a plate. The transport device can be used to transport heavy objects such as formwork elements, in particular formwork panels or formwork supports, barriers, posts or wooden panels. Of course, the transport device can also be used to transport bulk goods or loose objects, preferably when a base plate and side walls are provided. Further transport devices can also be transported in the folded state with one transport device. A fixing element of a folded transport device can be used to connect the transport devices to be transported to one another in the folded position in order to thereby secure them for transport. In order to be able to withstand high loads and forces during transport, the transport device can consist at least partially, preferably completely, of metal. In particular, the pivotable frame, which includes the side parts, can be made of metal. The side parts are connected to each other via joints. The joints can be hinge joints, for example. In the folded position, the transport device takes up the least amount of space and can therefore be easily stowed away. Preferably, in the folded position, the first and second side portions are aligned substantially parallel. The transport device can be brought into the unfolded position by parallel pivoting of the side parts. Parallel pivoting means that the first side parts are pivoted at the same time relative to the second side parts, as a result of which the frame can be folded up or unfolded. During the parallel pivoting, the first side parts each remain arranged parallel to one another. The second side parts also remain arranged parallel to one another during the parallel pivoting. The frame therefore forms a parallelogram when viewed from above in the unfolded position. The unfolded position may be a fully unfolded position where the frame forms a rectangle in plan view. In the unfolded position, the transport device forms a receiving space for objects. In the fully unfolded position, the receiving space has the greatest volume. In the folded position, the transport device forms no accommodation space or one with the smallest volume. An unfolded position does not necessarily have to be the completely unfolded position of the transport device. The transport device can preferably also be brought into several unfolded positions. The unfolded positions that do not correspond to the fully unfolded position can also be referred to as the intermediate position. The first and second side parts can be formed, for example, by struts or rods, preferably profiles, in particular hollow profiles, or side walls. The side walls can be designed over the entire surface or be formed by grids or frames, for example. The first side parts are each the same length. The first side parts are preferably of identical design. The second side parts are also of the same length. The second side parts are preferably also configured identically. The length of the first side parts and the length of the second side parts can be different or the same. The joints can be arranged at the ends of the side parts or offset to the ends of the side parts. Advantageously, in the unfolded position, several transport devices can be joined directly to one another in order to transport longer objects. In particular, a number of transport devices can be longitudinally connected in the unfolded state, for example by connecting them with the aid of connecting parts.

Unless otherwise stated, directional information such as “up” or “down” in this disclosure refers to the intended use of the transport device in the unfolded position.

In one embodiment of the invention, the fixing element is formed by a strut. The strut can be formed, for example, by a tube or a profile, preferably a hollow profile, in particular a square profile. The strut is preferably straight, i.e. unbent in the longitudinal direction. The strut can be removed from the side parts, in particular without tools, or can be pivotably arranged on at least one side part. The strut may be attachable to different side members, i.e. a first and a second side member.

However, it is preferred if the strut can be fastened to the two first or to the two second side parts in the unfolded position of the transport device. In this way, the fixing element can also serve as a support element for objects that are transported with the transport device. It is preferred if the strut can be fastened obliquely, ie not parallel, to all side parts. This creates a mechanical lock for the Frame created and it can be blocked a parallel pivoting of the side panels.

In an alternative embodiment of the invention, it is provided that the fixing element has two partial struts which are connected to one another via an articulated joint, the articulated joint being lockable. The partial struts can each be pivotably connected to a side part via a pivoting mechanism, in particular a rotary bearing or a rotary joint. The partial struts can be connected to the first two or to the two second side parts via a pivoting mechanism. In order to fix the transport device in the unfolded position, the articulated joint can be locked. The articulated joint can be designed as a hinge, for example, which can be locked by a locking element, so that pivoting of the partial struts relative to one another is blocked.

In a further embodiment it is provided that the fixing element is formed by an angle element which can be connected to a first and a second side part. One leg of the angle element can be connected to a first side part and another leg of the angle element can be connected to a second side part. The two legs can enclose an angle of 90° with one another. The angle element can preferably be detachable from the side parts without tools. Alternatively, one of the legs can be connected to a side part by means of a pivoting mechanism, while the other leg can be connected to another side part, preferably without tools.

In a further embodiment, the fixing element is formed by a surface element, in particular a hinged floor or a shelf. The surface element can thus serve as a support element for objects in the transport device. The surface element can in particular be detachable from the side parts without the use of tools. However, the surface element can also be pivotably connected to a side part by means of a pivoting mechanism.

So that the fixing element can be fastened to a side part, it is favorable if at least one side part has one or more dedicated fastening areas, for example fastening holes or fastening pins, to which the fixing element can be fastened. The fastening holes can, for example, be formed directly on the side parts, for example drilled into them. The fastening areas can also, for example, each have tabs with a fastening hole into which a fastening pin of the fixing element can be inserted. If a side part has several attachment areas, the unfolded position and thus the width of the transport device can be determined by the selection of the attachment area. For example, if the fixing element is a strut, an angle of the strut to the side parts can be defined by the choice of the fastening areas. Depending on the angle, the unfolded position is also determined.

It is advantageous if the fixing element has at least one fastening section with which the fixing element can be fastened to a side part and in which a fastening hole or a fastening pin is preferably arranged. The fastening pin on the fixing element can be inserted into a fastening hole on a side part, for example.

Provision can be made for the fixing element to be connected to one or two side parts via a swivel mechanism, in particular a swivel joint or a swivel bearing. For example, in the embodiment mentioned above, in which the fixing element is formed from partial struts, the two partial struts can each be connected to a side part via a pivoting mechanism. In order to fix the partial struts to one another, the aforementioned articulated joint can be locked. In other embodiments, the fixing element can be connected to only one side part via a pivoting mechanism. The advantage here is that the fixing element is captively connected to a side part and thus to the frame of the transport device.

A particularly advantageous variant of the invention results when the fixing element can be arranged in the unfolded position in a plane spanned by the frame. In this way, both the fixing element and the frame can serve as a support element for objects when the transport device is in the unfolded state. It is particularly favorable if, in the unfolded position, an upper side and/or an underside of the fixing element is flush with the side parts.

To increase the transport safety of objects, at least one of the first and/or one of the second side parts can each form a side wall of the transport device. The two first and/or the two second side parts can each form a side wall. A side wall within the meaning of the invention can be formed by a plate, a grid or a frame. A side wall prevents objects from falling off the transport device.

In addition or as an alternative, it can be provided that at least one side wall or at least one stanchion, preferably at least two or at least four side walls or stanchions, is/are connected to the pivotable frame. For example, one or more side walls or stanchions can be connected to the first and/or second side parts. The side walls or stanchions can be arranged above the frame and are preferably oriented substantially vertically. The at least one side wall or the at least one stanchion can also be removable from the frame, preferably removable without tools. The at least one side wall or the at least one stanchion can in particular be releasably connected to the frame without tools.

The side walls can also represent parts of a box. Advantageously, a hinged cover and a base, which is preferably fixed to the frame, can therefore also be connected to the side walls.

Since several transport devices are usually brought to a construction site, it is advantageous if transport receiving elements are arranged on an upper side of the side walls or the stanchions for placing another transport device of the same type on the transport device. The transport receiving elements can be set up, for example, to receive the frame or feet of another transport device of the same type. A transport receiving element can form a receptacle formed from upwardly protruding tongues, with which lateral displacements of the additional transport device placed thereon can be prevented.

Feet can be connected to the frame on an underside of the transport device. In particular, feet can be mounted exclusively on the first or exclusively on the second side parts.

A particularly compact folded position can be achieved if all the first and second side parts are arranged essentially parallel to one another in the folded position of the transport device.

The transport device according to the invention can be used in the unfolded state for transporting formwork material, such as formwork elements, props, formwork panels and other formwork accessories. For this purpose, the transport device can be unfolded and fixed with the fixing element. The formwork elements can then be placed in the resulting receiving space. If the transport device has side walls or stanchions, these secure the formwork elements.

In order to facilitate the transport of several transport devices, at least two transport devices can be reversibly detachably connected to one another in the folded position. For example, a connecting element, in particular a fixing element of a transport device, can be connected to the side part of a transport device and the side part of another transport device. The connected transport devices can be arranged directly next to one another. It is also possible that at least one further transport device is arranged in the folded position between the two transport devices connected by the connecting element. This results in a compact combination of folded transport devices. It is thus possible to move a plurality of transport devices, which also form a kit, into a transport position by connecting a connecting element, in particular a fixing element, to at least two side parts of different transport devices.

The transport device according to the invention can be used in the unfolded state for the transport of several transport devices that are in the folded position. In order to additionally secure the transport devices to be transported in the folded position, a fixing element can optionally connect at least two transport devices to one another in the folded position in a reversibly detachable manner. For example, the fixing element can be connected to the fastening areas of the side parts of two transport devices that are in the folded position.

The transport device according to the invention is not only suitable for transporting objects such as formwork material. In the unfolded position, the transport device can also be used to protect against floods, mudslides or avalanches. The unfolded position may, but need not, be the fully unfolded position. The transport device can also be used in another unfolded position as protection against floods, mudslides or avalanches. Several transport devices are preferably used to protect against floods, mudslides or avalanches. The transport devices can be used side by side and/or stacked on top of one another. Several transport devices can also be connected to one another with connecting elements in order to create a network of transport devices. In the unfolded state, the transport device can be filled with objects, for example stones, or with bulk material such as gravel or sand To prevent shifts caused by the pressure generated by floods, mudslides or avalanches. The transport device can be filled with a filling weight of at least 600 kg, for example. The filling weight can depend on the pressure of the water or the avalanche. For tightness, a tarpaulin is preferably placed over at least one side wall of the transport device and preferably fixed against floating. The fixation can take place, for example, by means of fastening means such as clamps or by placing a weight, for example using sandbags. The tarpaulin can also be fixed to an upper side of the side wall. Alternatively, plates that are weighed down can also be used.

The invention is described in more detail below with reference to figures, to which, however, it should not be restricted.

1 shows a transport device 1 according to the invention according to a first embodiment in a fully unfolded position. The transport device 1 has a pivotable frame 2 with two first side parts 3 and two second side parts 4 . The side parts 3, 4 forming the frame 2 preferably have hollow square profiles. The two first side parts 3 are arranged essentially parallel to one another. The two second side parts 4 are also arranged essentially parallel to one another. The side parts 4 are pivotally connected to the two first side parts 3 via joints 5, in particular rotary joints 5a. As a result, the transport device 1 can be moved from the fully unfolded position shown into a folded position to be described in more detail (see FIG 3 ) are transferred. Swivel joints 5a with at least one rotational degree of freedom can be used as joints 5 . In particular, pivot joints 5a can be used in which a pivot pin (not shown) connected to a first joint part is rotatably received in one or more pivot holes arranged on a second joint part.

In the embodiment shown, the joints 5 on the two first side parts 3 are not arranged offset at their end regions 51 but inward towards the center of the second side parts 4 . However, the two second side parts 4 can also be connected to the end regions 51 of the first side parts 3 via the joints 5, as is the case in the second embodiment described in more detail below.

In the fully unfolded position of the transport device 1, the frame 2 forms a rectangle in plan view. The first side parts 3 are essentially aligned at right angles to the two second side parts 4 . A fixing element 6 is provided in order to fix the transport device 1 in the unfolded position. In the illustrated embodiment, the fixing element 6 is formed by a strut 7 and can be completely detached from the frame 2 without tools. By attaching and arranging the strut 7 obliquely, ie not parallel, to the side parts 3, 4, the frame 2 is locked and the parallel pivoting of the side parts 3, 4 is blocked. The fixing element 6 is fastened to the two first side parts 3 in a detachable manner without tools. It is also possible that the fixing element 6 can only be detached from a first side part 3 without tools, but is pivotably connected to the other first side part 3 . In order to fasten the fixing element 6 to the two first side parts 3 , a fastening section 8 is provided on each of the two opposite ends of the strut 7 , which fastening section can be connected to fastening areas 9 on the first side parts 3 . The fastening sections 8 each have a protruding fastening pin (not shown) on an underside of the fixing element 6, which can be inserted into a fastening hole 9a of a fastening strap 9b (see FIG 6 ) can be carried out on a first side part 3. The two first side parts 3 can each also have a plurality of dedicated fastening areas 9, each with a fastening strap 9b in which a fastening hole 9a is arranged (see FIG detail view 2A) . Due to the presence of several fastening areas 9 on the first side parts 3, the transport device 1 can also be fixed in an unfolded position other than the fully unfolded position. As a result, the width B of the transport device 1 can be fixed.

The fastening tabs 9b each preferably protrude from an underside of the respective first side part 3 . The fixing element 6 can thus be arranged in a plane spanned by the two first 3 and the two second side parts 4, whereby the fixing element 6 can also serve as a support element for objects to be transported next to the side parts 3, 4 of the frame 2.

In the unfolded position, the transport device 1 can be used for the transport of objects, such as formwork elements (not shown). In order to secure the objects against falling out during transport, the transport device 1 has four side walls 10 which are connected to the frame 2 . The two side walls 10 located on the narrow sides of the transport device 1 are formed by removable lattice frames 11 . The lattice frames 11 have laterally overhanging connection extensions 12, which can be connected to connection straps 13 on the side walls 10 of the broad sides of the transport device (see in particular 4 ). The connecting extensions 12 can be connected to the connecting straps 13, for example by cotter pins. As in 4 can be seen, the two lattice frames 11 can also be opened by pivoting. For this purpose the cotter pins on one side of a lattice frame 11 can be removed. The two side walls 10 on the broad sides of the transport device 1 are formed by frame walls 14 with a diagonal strut 15 . Of course, the frame walls 14 can also be replaced by lattice frames 11 . All side walls 10 can also be formed by panels (not shown).

Extensions 16 with transport receiving elements 17 are arranged on an upper side 50 of the frame walls 14, on which another transport device 1 of the same type can be placed, as a result of which the stacking of transport devices 1 is made possible. In order to secure the additional transport device 1 , the transport receiving elements 17 each have securing tongues 19 which protrude upwards and are preferably angled outwards on two outer sides of the transport device 1 and which each delimit a receptacle 18 . The transport receiving elements 17 can also be formed by plate elements with a curvature.

On an underside 20, the transport device 1 has feet 21, which protrude downwards from the first side parts 3 in the embodiment shown. Stand plates 22 can also be mounted on the underside of the feet 21 . The feet 21 or the base plates 22 of a further transport device 1 can be accommodated in the transport receiving elements 17 in order to stack a plurality of transport devices 1.

In order to be able to stow the transport device 1 with only a small amount of space after transport, the transport device 1 can be converted into a folded position by pivoting the side parts 3, 4 in parallel. The folded position of the transport device 1 is in 3 shown. In the folded position, all of the side parts 3, 4 are arranged essentially parallel to one another. The first side parts 3 rest against the second side parts 4 . In this way, the transport device 1 takes up very little space.

2 also shows an unfolded position of the transport device 1, but this is not the fully unfolded position. The unfolded position in 2 can also be referred to as an intermediate position. In this position it can be seen that the frame 2 does not form a rectangle in a top view in this position, but rather a parallelogram with sides that are not arranged at right angles. In the illustration shown, the fixing element 6 is not connected to the side parts 3, 4, so that the transport device 1 can be transferred into the folded position by pivoting in parallel.

The 5-7 show a second embodiment of the transport device 1 according to the invention. The mode of operation of the second embodiment of the transport device 1 essentially corresponds to the mode of operation in FIGS 1-4 shown embodiment, which is why only the differences between the two embodiments will be discussed below.

Like the first embodiment, the second embodiment also has first side parts 3 and second side parts 4, which are connected to one another via joints 5, so that a pivotable frame 2 is formed. In contrast to the first embodiment, the joints 5 are arranged on the outermost end areas 51 of the first side parts 3 . However, the exact arrangement of the joints 5 is not relevant to the invention. The joints 5 can also be arranged offset to the outermost edge regions, as in the first embodiment. Furthermore, the joints 5 have increased stability in this embodiment. A first Hinge part 23 having a through hole is interposed between an upper side bracket 24 and a lower side bracket 25 and connected to them via a hinge pin. Of course, the more stable joints 5 of the second embodiment can also be used in the transport device 1 of the first embodiment.

Furthermore, no side walls 10 are provided in the transport device 1 according to the second embodiment, but rather vertically arranged stanchions 26 are connected to the frame 2 . The stanchions 26 are each arranged at a corner of the frame 2 of the transport device 1 . As in the first embodiment of the transport device 1 , transport receiving elements 17 are arranged on the upper head ends 27 of the stanchions 26 for receiving further transport devices 1 of the same type.

Like the first embodiment of the transport device 1, the second embodiment of the transport device 1 can also be moved by parallel pivoting of the side parts 3, 4 between an unfolded position ( 5 ) and a folded position ( 7 ) transfer. 6 shows the transport device 1 of the second embodiment in a further unfolded position.

In the 8A-O the transport device 1 is shown in a fully unfolded position in plan view with different embodiments of the fixing element 6. The 9A-O show the transport device 1 in plan view with the different embodiments of the fixing element 6 in an intermediate position. The different embodiments of the fixing element can in the above-described embodiments of the transport device 1 according to 1-7 be used.

8A shows a transport device 1 in the fully unfolded position, in which the fixing element 6 is designed as a straight strut 7 throughout. The strut 7 is detachably fastened to the two opposite first side parts 3 . Of course, the strut 7 can also be detachably attached to the two second side parts 4, as is shown in 8B is shown. A strut 7 designed as a fixing element 6 is already in the embodiments according to the preceding 1-7 shown. 9A and 9B show the in 8A or. 8B Transport device 1 shown in an intermediate position in which the strut 7 is detached from the frame 2. If the strut 7 is not fastened to the side parts 3, 4, the transport device 1 can be transferred into the folded position.

8C shows a transport device 1 in the fully unfolded position, in which the fixing element 6 is also designed as a strut 7 . In contrast to the embodiments according to 8A and 8B However, the strut 7 cannot be completely detached from all side parts 3, 4 without tools, but is connected to one of the side parts 3, 4 via a swivel mechanism 28, in particular a rotary joint 29. In this way, the strut 7 can be folded up or to the side after releasing the fastening from the other side part 3, 4 in order to convert the transport device 1 into the folded position. The strut 7 can be pivotably connected to a first 3 or to a second side part 4 . The axis of rotation of the pivoting mechanism 28 is preferably arranged parallel to the main plane spanned by the frame 2 in the unfolded position, but can also be oriented perpendicularly to the main plane.

8D shows a transport device 1 in the fully unfolded position, in which the fixing element 6 has two partial struts 30a, 30b. The partial struts 30a, 30b are connected to one another via a lockable articulated joint 31. Furthermore, the partial struts 30a, 30b are each connected to a first side part 3 via a pivoting mechanism 28, in particular a swivel joint 29. The axes of rotation of the rotary joints 29 are oriented essentially perpendicularly to the main plane spanned by the frame 2 in the unfolded position. The articulated joint 31, the axis of rotation of which is also aligned essentially perpendicularly to the main plane spanned by the frame 2, can be lockable so that pivoting of the partial struts 30a, 30b relative to one another is blocked. By locking the buckling element 31, the transport device 1 is also blocked in the fully unfolded position. 9D shows the in 8D shown transport device 1 in an intermediate position in which the partial struts 30a, 30b are pivoted to each other.

8E shows a transport device 1 in which two fixing elements 6 are provided. The fixing elements 6 are each designed as struts 7 which are fastened to a first 3 and a second side part 4 in order to fix the transport device 1 in the unfolded position. The attachment can be done for example by means of locking pins. The struts 7 can each be designed so that they can be detached from all side parts 3, 4, preferably without tools. As in 9E shown, the struts 7 can only be detached from one side part 3, 4 - in the embodiment shown from the first side part 3 - preferably without tools and with the other side part 3, 4 - in the embodiment shown with the second side part 4 - but via a swivel mechanism mus 28, in particular a rotary joint 29 connected. The axes of rotation of the rotary joints 29 are oriented essentially perpendicularly to the main plane spanned by the frame 2 in the unfolded position.

8F shows a transport device 1, in which two fixing elements 6 are also provided. The fixing elements 6 are each designed as angle elements 32 with two legs 32a, 32b oriented essentially at right angles to one another, which are fastened to a first 3 and a second side part 4 to fix the transport device 1 in the unfolded position. The attachment to the side parts 3, 4 can be done with the help of locking pins 33, for example. The angle elements 32 can each be detachable from all side parts 3, 4 are formed. As in 9F shown, the angle elements 32 are, however, only from one side part 3, 4 - in the embodiment shown from the second side part 4 - preferably detachable without tools and to the other - in the embodiment shown with the first side part 3 - firmly connected, for example welded. 9F shows the in 8F shown transport device 1 in an intermediate position.

In a further embodiment of the transport device 1, which 8G is shown, two fixing elements 6 are also provided, which are designed as angle elements 32 . In contrast to the previous embodiment according to 8F However, the angle elements 32 are each connected to the first side part 3 or the second side part 4 (as shown) via a swivel mechanism 28, in particular a rotary joint 29, on one of the legs 32a, 32b. The axes of rotation of the rotary joints 29 are preferably parallel to the main plane spanned by the frame 2 in the unfolded position, but can also be arranged perpendicularly to the main plane. After pivoting the angle elements 32, the transport device 1 can be transferred to the folded position (see FIG 9G)

8H shows a transport device 1 with two fixing elements 6. The fixing elements 6 are designed as struts 7 and arranged crossed. The struts 7 can, but do not have to, be connected to one another at a crossing point 34, for example welded. The connection at the crossing point 34 can also take place via a connecting joint. The fixing elements 6 can be completely detached from the side parts 3, 4, as in the intermediate position according to FIG 9G is evident. The fixing elements 6 can be attached to the first side parts 3 (as shown) or to the second side parts 4 in the unfolded position. It is also possible for the struts 7 to be pivotably connected to one of the side parts 3 via pivoting mechanisms 28, in particular rotary joints 29. In this case, the axis of rotation of the pivot joints 29 would lie parallel to the main plane spanned by the frame 2 in the unfolded position.

In 81 an embodiment of the transport device 1 is shown which is similar to the embodiment according to FIG 8H is designed. In contrast to the embodiment according to 8H However, the struts 7 are not crossed, but are arranged at an angle to one another and are connected to one another at an end region 35 . When the transport device 1 is in the fully unfolded position, the struts 7 are fastened to the first side parts 3 . Alternatively, the struts 7 can be attached to the second side parts 4 . The fixing elements 6 can preferably be detachable from the side parts 3, 4 without tools. However, it is also possible for the struts 7 to be connected to the first 3 or second side parts 4 via pivoting mechanisms 28, in particular rotary joints 29, as is the case in the present embodiment (see also 91 ). The axes of rotation of the pivot joints 29 are oriented parallel to the main plane spanned by the frame 2 in the unfolded position.

8y shows a transport device 1 also with two fixing elements 6, which are designed as chains 52, belts or ropes. The fixing elements 6 are similar to the embodiment according to FIG 8G , Crossed and can be attached to the first side parts 3 (as shown) or to the second side parts 4. After at least one fixing element 6 has been detached from at least one side part 3, the transport device 1 can be transferred into the folded position (see FIG 9y) .

8K shows a transport device 1, in which the fixing element 6 is formed by a surface element 36, in particular a plate 37. In the fully unfolded position, the surface element 36 is fastened to the first side parts 3 and can be completely detached from the first side parts 3, preferably without tools (see FIG 9K) . Of course, the surface element 36 can also be attached to the second side parts 4, preferably without tools, as is shown in 8L or. 9L is shown. A further possibility is that the surface element 36 can be fastened to both the first 3 and the second side parts 4, preferably without tools, as is shown in 8M or. 9M is shown. Is possible in accordance with these embodiments 8 KILOMETERS or. 9K-M also that the surface element 36 is connected via a pivoting mechanism 28 to one of the side parts 3, 4 and for transferring the transport device 1 from the on folded position is folded up into the folded position using the pivot mechanism 28.

8N shows a transport device 1 with two fixing elements 6, which are designed as surface elements 36. The surface elements 36 are each rotatably connected to the two first side parts 3 via pivoting mechanisms 28 , in particular rotary joints 29 . In order to fix the transport device 1 in the fully unfolded position, the surface elements 36 can be arranged in such a way that the upper sides 38 and the lower sides 39 ( 9N) of the surface elements 36 are arranged parallel to the main plane spanned by the frame 2 in the unfolded position. The end faces 40 of the surface elements 36 then lie against the first side parts 3 and thereby block pivoting of the frame 2. The surface elements 36 can also be fixed in this position by holding elements (not shown). In order to move the transport device 1 into the folded position, the surface elements 36 can be rotated by approximately 90° so that the upper sides 38 and the lower sides 39 are arranged perpendicular to the main plane spanned by the frame 2 in the unfolded position. In this way, the end faces 40 are no longer in full contact with the first side parts 3 . This allows the frame 2 to pivot.

8O shows a transport device 1 with a fixing element 6, which is connected to the first side parts 3 via pivoting mechanisms 28, in particular rotary joints 29. Of course, it is also possible for the fixing element 6 to be connected to the second side parts 4 instead of the first side parts 3 . The fixing element 6 has a strut 7 and two connecting legs 42 which are connected to the end sides of the strut 7 and which are rotatably connected to the first side parts 3 via the pivoting mechanisms 28 . The connecting legs 42 are arranged essentially at right angles to the strut 7 . In the fully unfolded position, the connecting legs 42 are aligned parallel to the first side parts 3 and rest against them, as a result of which a parallel pivoting of the first 3 relative to the second side parts 4 is blocked. In order to move the transport device 1 into the folded position, the fixing element 6 can be rotated so that the connecting legs 42 are arranged essentially perpendicular to the main plane spanned by the frame 2 in the unfolded position and are no longer parallel to the first side parts 3.
