Description

transport system

The present invention relates to a transport system for piece goods with at least one carrying bag made of a flexible material and with a frame having a bottom member, at least two side members, wherein the side members are connected to the bottom member so that they from a first upright position, in which Side elements form a substantially right angle with the bottom element, can be brought into a second folded position in which the side elements extend substantially parallel to the bottom element, and at least one cross member having a first and a second end portion, wherein the transport pocket with the cross member connected is.

Such transport systems are known from the prior art. They serve the transport of general cargo, such as automotive accessories, from the manufacturer to the customer. In this transport chain, the transport systems or transport containers are loaded in one direction only, while in the other direction the empty transport systems have to be transported back to the manufacturer. In order to minimize the transport volume during the return transport of the systems, the known transport systems are optimized so that the frame of the system can be folded, the side elements or side walls are folded so that they rest in the folded state on the floor of the transport system, so that the transport system is significantly reduced in height and in volume.

In the transport systems known from the prior art, the individual goods to be transported are received within the transport system in transport bags made of a flexible material. This allows the transport of a plurality of parts in a single transport system, with the parts in the pockets being protected against damage due to mutual contact or contact of the parts with the frame of the transport system. The pockets are usually flexible U-shaped tracks, which are attached by means of eyelets on cross members, which are connected to the side walls of the frame.

Here are the from the prior art, for. As the US 6,540,096 B1, known transport bags or cross member for mounting the bags firmly and not detachably connected to the side walls. Therefore, in the transport systems of the prior art, the transport bags can only be exchanged or replaced with the aid of appropriate tools. In addition, the fixed connection between the pockets or the cross members and the side walls to the fact that when folding the walls often the pockets between the wall elements clamped and thereby damaged.

Compared to this prior art, the present invention has the object to provide a transport system, which offers a high degree of flexibility with respect to the goods to be accommodated therein and which avoids the disadvantages known from the prior art.

This object is achieved in that a transport system is provided, wherein at least two of the side members have at least one receptacle for the cross member, wherein the cross members are detachably connectable to the receptacles and inserted into the bottom member to bring the side members in the folded position.

It is particularly advantageous if two cross members are provided.

The removable side elements make it possible to remove the transport bags before folding the side walls and insert in the bottom element of the transport system, so that it can not be damaged by the folding side walls. In addition, the arrangement according to the invention makes it possible to use different transport pockets in the same frame. In particular, the sender has the opportunity to use bags of different lengths, since cross members of different lengths can be absorbed by the receptacles of the side walls, wherein the cross member extend either along the short or the long side walls.

Preferred is an embodiment of the transport system in which the cross members are connectable to the side members such that the first end portion of the cross member is connected to a receptacle of a first side member and the second end portion of the cross member with a receptacle of a second side member, wherein the cross member between two side elements extend. In this way, prevent the cross member beyond that the opposite side walls collapse. Are in the unfolded state, moreover, the side members connected to the cross members between the other two side members arranged so serve the removable cross member as a locking element for all the side walls of the frame.

In a further embodiment, the two end portions of a cross member are connected to the receptacles of a single side member such that the cross member of only one single side element is held. In order to obtain the greatest possible flexibility of the frame, the receptacles may be provided such that the end portions of a cross member are selectively connectable to the receptacles of two different side members or with the recordings of a single side member.

In the simplest embodiment, the receptacles have substantially U-shaped elements, the open end of which points away from the bottom element, so that a cross member or its end portion can be inserted from above into the receptacle.

As an alternative to the U-shaped elements, the receptacles may have elongated holes which are narrower at their lower end than at their upper ends. In this way, provided with appropriate mushroom heads cross member can be attached to the recordings.

In a preferred embodiment, the receptacles are provided as recesses in the side elements of the frame. This has in addition to the simple production method the advantage that it is possible to design the images such that they do not protrude beyond the inner surface of the side elements, so that the other side elements can be easily moved when folding over the recordings.

It will be understood that the side elements include both solid walls, ie. H. Plates, can be as well as open frames, z. As grid frame, which allow a load from the sides.

In a particularly preferred embodiment of the invention, the receptacles for the cross member are pivotally connected to the side walls. Thus, the same receptacles can be used both for the attachment of cross members to two side members as well as for the attachment of cross members to a single side member. For this purpose, it is expedient if the recordings are pivotable by means of hinges. The pivoting range is expediently about 90 °. Moreover, it is advantageous if the axes about which the receiving means are pivotable, are arranged in the region within the side walls.

In a preferred embodiment, the receptacles or their hinges are resiliently biased in one direction. In this way, when the cross member is always a certain tension of the recording against the cross member is achieved so that it sits firmly and essentially without play in the recording. In addition, it allows the resilient bias, which preferably biases the hinges in such a way that the receptacles are pushed away from the side element into the interior of the transport system. to use the recordings as latches for those side elements with which the recordings are not connected. The recordings in a first position block the Verschwenkweg the other side walls into the interior of the transport system. Only by pressing the recordings against the spring force on the side elements, so that the recordings occupy a second position, the Verschwenkweg the other side elements is released, so that they can be folded freely.

Particularly preferred is an embodiment of the invention, in which the receptacles are made of sheet metal with a thickness of 2 to 10 mm, preferably from 3 mm to 6 mm and particularly preferably 5 mm. Such sheets wear in the folded to the side elements state only slightly, so that the side elements with which the recordings are not connected, can be moved past due to the manufacturing tolerances or due to a game in the hinges on the folded recordings.

In a preferred embodiment, two perpendicular abutting side members are configured such that they interlock in the upright state, preferably in the manner of a dovetail connection, that in one direction, a substantially rigid connection is formed.

If, in this embodiment, the side element which is not connected to the receptacles is to be folded over, it is expedient if the receptacles have a minimum distance from the side element which is to be folded, which also makes it possible to flip the side element to be folded over in the first position of the receptacles far to pivot, or fold over, that the mutually engaged side elements are disengaged. If the side elements are out of engagement, the side elements connected to the receptacles can be moved so far outward that the side element to be folded over can be moved past the receptacles applied to the other side elements.

It is particularly expedient if the recordings are chamfered or rounded on their side facing the side element to be folded.

An alternative embodiment of the invention is preferred in which at least some of the side elements are L-shaped at least in sections, so that the side elements extend at least partially over two sides of the transport system. In this way, a space is formed in the edge region of the transport system, in which the receptacles are received in their folded to the side elements position, so that the other side elements are freely pivotable in the interior of the frame. To one the other side elements are freely pivotable in the interior of the frame. In order to allow a free folding of the associated with the shots side elements, it is expedient if the side elements are designed L-shaped only in the area of the shots, while the side elements, especially in the area in which they are posted on the bottom element, just and do not extend around the corner of the frame.

Here, an embodiment is preferred in which the L-shaped side member has a short and a long leg, wherein the long leg extends over substantially the entire length of one side of the frame and wherein the short leg has a length which is substantially the thickness Recording, in particular the thickness of the sheet of recording corresponds. The length of the short leg is from 2 mm to 10 mm, preferably from 3 mm to 6 mm and particularly preferably 4 mm.

The transport bags are preferably U-shaped elements made of a flexible sheet material, in which the cargo to be transported from above or from the side can be inserted. It is expedient if the transport bags have at least one eyelet through which engages a cross member, so that the transport bags are displaceable along the cross member. Also alternative attachment possibilities for the pockets, which in particular ensure a displacement of the pockets, e.g. Hooks or stitched loops may be provided.

This embodiment allows a displacement of the transport pockets, whereby an arrangement of several levels of transport bags one above the other is possible without the loading of the lower pockets would be hindered by the pockets arranged above.

To prevent slippage of the eyelets of the transport pockets of the cross member, this is completed in a preferred embodiment at the ends with an element which has at least in one direction a greater extent than the corresponding eyelets of the transport pockets.

Particularly preferred is an embodiment of the invention in which the cross member is connected to at least one, preferably with two fastening elements with the bottom element. In this way, the cross member and the other elements of the frame form a unit, so that the cross member and the pockets can not be lost during operation. In addition, it is expedient if the fastening element is at least partially elastic, so that the fastening element biases the recorded in the receptacles of the side members cross member against the bottom element. For this it is necessary that the fastener in the relaxed state in about as long or slightly shorter than the distance between the recording, ie the cross member in the engaged state, and the bottom element. In order to remove the cross member from the receptacles, it is necessary in this embodiment to overcome the spring force of the fastener to move the cross member out of the receptacles. In this way, falling out of the cross member from the recordings during transport, for example, by vibrations, prevented.

Even if the fastening element in a preferred embodiment is a rope, so alternatively or additionally, bands, suitable chains or rigid elements can be used as fastening elements in the context of this invention.

In particular, it is expedient if the fastening element is a non-stretchable and substantially inelastic element, while the resilient bias of the fastening element is provided by an elastic element which is connected to the fastening element and the bottom element.

Preferred is an embodiment of the invention in which more than one cross member is connected to the fastening element in the manner of a ladder, in particular a rope ladder, so that when a first cross member is received in the receptacles of the side members between the first cross member and the bottom member at least a further cross member is provided, which is also connected to the fastening element. In this way, when the uppermost cross member is inserted into the receptacles, the further cross member held by the fastener, it is advantageous if the other cross member are additionally arranged between the receptacles and the side members so that they are not free inside the Hang transport systems and swing there.

Advantageous is an embodiment of the invention, wherein the receptacles are substantially L-shaped, wherein the short leg of the L is provided for receiving a cross member, while the long leg is arranged so that further cross member between the long leg and a side member can be. It is particularly expedient recordings at their end receiving the cross member by about the width of a cross member are wider than at its other end. In this way, further cross members between the receiving and side member can be arranged in the areas under the cross member received by the recording. This is how the free movement of the Ren associated with the fastener cross member limited in the transport system and higher loads can be removed via the other cross member. At the same time, those ends of the seats receiving the cross beams may extend closer to the other side walls so as to form a latch for the side walls as previously described.

In a further particularly preferred embodiment, the side elements on guides for the cross member, in which the cross member from the bottom element to the receptacles of the side walls are movable. These guides may be provided alternatively or in addition to the rope elements. It is expedient if each cross member is guided by two guides, in particular on opposite side elements.

In a preferred embodiment, the guides of opposing cross members at the upper end of the side members have a greater distance from one another than at the lower end thereof. In this way, for example, by means of an elastic cable element against each other biased cross member by means of pulling means, such as belts, from one side of the transport system from the ground to the upper position, i. in transportable condition, be brought.

FIG. 12 shows a plan view of the embodiment of FIG.

FIG. 1 shows a three-dimensional view of the frame of the transport system for piece goods according to the invention. In the embodiment shown, the frame has a bottom element 1, two long side elements 2 and two short side elements 3. Both the short 3 and the long 2 side elements are hinged to the floor element 1 with the aid of hinges such that the side elements consist of the upright position shown in FIG. 1, in which the side elements 2, 3 have a substantially right angle with the floor element 1 form, can be brought into a folded position. By folding the side elements 2, 3, wherein the side elements 2, 3 extend in the folded state substantially parallel to the bottom element 1, the height of the frame is substantially reduced, so that the transport system to save space to senders, such as an automotive supplier, are sent back can. The volume of empty cargo is thus significantly reduced.

In order to be able to bring the side elements 2, 3 into the folded position provided for the return transport, the short side elements 3 must first be folded down before the long side elements 2 can be folded over, since in the upright position the short side elements 3 fold over Prevent side elements 2.

In order to allow a simple and smooth folding of the frame of the transport system according to the invention, the hinges of the side walls 2, 3 are struck at different heights on the bottom 1 of the frame. As can be seen in Figure 1, the short side walls 3 struck directly on the bottom 1 of the frame, while the long side walls 2 are struck above the hinges of the short side walls 3. In this way, the long side walls after folding the short side walls 3 can be placed on top of this, so that a substantially parallelepiped state of the folded frame is achieved.

It is particularly advantageous, since the long side walls overlap each other in the folded state, these are also folded at different heights hinged to the bottom 1. In this way, the side elements can be folded very space-saving. FIG. 9 shows a sectional view through such an embodiment of the frame, wherein the side elements 2, 3 are shown in the folded-over state. Clearly, they are at different heights, i. Distances from the bottom 4 of the bottom element 1, arranged hinges 5, 6, 7 to recognize. In the embodiment shown here, the bottom element 1 has a recess 8, in which, even with folded side walls 2, 3, the remaining elements of the frame. the cross beams and the transport bags are included.

FIG. 2 shows a broken inside view of a transport system according to the invention. Essential for the operation of the system according to the invention are the receptacles 9, which are connected in the illustrated embodiment with the long side walls 2 and which serve to receive the cross member 10. The receptacles 9 consist of sheets which are hinged to the long side walls 2 and which have recesses 11 at their upper end. In the recesses 11, the cross member may be inserted such that the cross member 10 extend substantially parallel to the short side walls 3, wherein the end portions 12 are received in the recesses 1 1 of the receptacles 9. Since the receptacles 9 are hinged by means of a hinge on the long side walls 2, as an alternative to the cross members 10, which are shown in Figure 2 and whose length corresponds substantially to the length of the short side walls 3, and cross members are used, which Have length that corresponds substantially to the length of the long side walls 2, wherein the side supports are received in receptacles 9, which are connected to the same length side wall. In this way, the cross member then extend substantially parallel to the long side walls 2. The preferred and illustrated in Figures 2 to 5 embodiment of the receptacles 9 is particularly advantageous because the sender can decide whether he long or short pockets to depending on his decision, the frame can be equipped with short or long cross members and accordingly with short or long pockets. The receptacles 9 shown in FIGS. 2 to 5, as shown in FIG. 5, are spring-biased with the aid of foam blocks 13 embedded in the long side walls 2. The bias causes that one end of the receiving plate 9 protrudes from the side wall 2.

The resiliently protruding from the side walls 2 sheets 9 prevent the short side walls 3 can fold. Only when the sheets 9 are pressed against the long side walls 2, the Verschwenkweg for the short side walls is free and diees can be folded. In this way, the receiving plates 9 form a closure for the short side walls 3. Thus, the short side walls 3 can still be folded when the recording plates 9 are folded to the long side walls 2, have the short side walls 3 as shown in Figure 5 sufficient play to the long side walls 2, so that the short side walls 3 can be moved past the receiving plates 9 in the folded-over position. In addition, the recording plates 9 are only 6 mm thick, so that they applied to the wall 2 does not apply significantly.

As an alternative to the arrangement shown in FIG. 5, recesses for the receptacles 9 can be provided in the side walls 2, which in the folded position terminate flush with the inner surface of the long side walls 2, so that the short side walls 3 are without the one shown in FIG Game can be folded.

In an alternative embodiment, shown schematically in Figure 10, the long side walls 2 'are L-shaped, with the short legs 2A' extending around the corner to the side of the short side walls 3 '. In this way, a space is formed behind the short legs 2A 'of the long side walls, which receives the receiving plates 9' in their folded state, so that the short side walls 3 'can be folded down. In this embodiment, it should be noted that the short legs of the L-shaped side walls 2 'do not extend to the bottom element in order to continue to allow unimpeded folding of the side walls 2'. Thus, an embodiment is preferred in which the short leg 2A 'extends only to just below the lower end of the receiving plate 9'.

In the embodiment not shown to scale in Figure 9, the length of the short leg 2A 'of the long side wall is slightly over 6 mm, so that the short side wall 2' can easily be moved past the 6mm thick receiving plate 9 '. In Figure 2, the cross member 10 are shown stored on the bottom element 1. With each cross member 10, 14, 15 a plurality of pockets 16 are connected, wherein in the schematic views of Figures 2 and 3 each only one pocket 16 per cross member 10, 14, 15 is shown. In this case, the pockets 16 are connected to the cross members in such a way that the cross members pass through rings 17 sewn with the pockets 16. In this way, the pockets which are arranged one above the other in the transportable state (see Figure 3) can be displaced laterally relative to one another, so that the pockets can be loaded and unloaded in different planes. The cross members 10, 14, 15 are connected to each other by means of two cables 18 in the manner of a rope ladder, the cross members 10, 14, 15 forming the rungs of the ladder.

In order to bring the transport system in the ready for loading state, the respective upper cross member 10 are inserted into the recesses 1 1 of the recording plates 9. Thus, the recorded in the sheets 9 cross member 10 does not fall out of the recesses, the ropes 18 at their lower ends knotted rubber elastic portions 19 which bias the connected to the cross members 10 ropes against the bottom element 1, that the cross member 10 only by Overcome the elasticity of the rubber-elastic elements 19, the recesses 11 of the recording plates 9 can leave. The other connected to the cables 18 cross member 14, 15, however, are held only by the ropes 18.

In order to prevent the cross members 14, 15 from wandering around, the cross member 10 is pulled upwards by the base element 1 between the receiving plates 9 and the short side wall 3 and inserted into the recesses 11 of the plates 9. In this way, the further cross member 14, 15 between sheet 9 and short side wall 3 are fixed so that they are not freely movable in the interior of the transport system. For this purpose, the receiving plates are narrower at its lower end than at its upper, provided with the recess 1 1 end. The projection which has the area of the recess 11 opposite the lower portion of the receiving plate, is substantially equal to the width of the cross member 10, 14, 15th

Since the recording plates 9 are biased so that they protrude from the long side walls 2, the upper cross member 10 in the recesses 1 1 of the recording plates 9 are also clamped.

FIG. 4 shows a schematic lateral sectional view along the long side walls 2. The three superimposed layers of pockets 16, which are connected to the cross members 10, 14, 15 by means of rings 17, can be seen in particular. FIGS. 6 to 8 show an alternative embodiment of the transport system according to the invention with several variations thereof.

Unlike the embodiments of the other figures, in the embodiment illustrated in Figure 6, the cross members 10 "are received in guide rails 20 at their ends and not connected to the floor member by means of a cable Transport system from up to connected to the guide rails 20 shots 21 movable.

In Figure 7, the guide rail 20 according to the invention is shown schematically. In this case, the guide rail 20 is connected at a distance from the long side wall 2 "of the transport system, wherein the ends of the cross member 10" flanges 22 which between the long side wall 2 "and the guide rail 20 engage, so that the cross member 10" guided on the Rail elements 20 rolls. In order to be able to pull the cross members 10 "upwards from the bottom of the frame, they are provided with bands 22, 23 to which the user of the transport system can pull." In order to fix the cross members 10 "in the receptacles 21, they are at the opposite ones Ends of the frame provided cross member 10 "connected to each other by means of an elastic band 24 and biased against each other.

In the preferred embodiment shown in Figure 8, the guide rails 20 'provided at the opposite ends of the transport system are not parallel to each other, but diverge from each other as seen from the side so as to be spaced further apart at the upper open end of the frame than at the bottom The End. In this way, the bias due to the elastic band 24 between the cross members 10 "is reinforced, and the cross member 10" can be conveniently pulled up one after the other, without one of the carrier again along its guide rails 20 'slides down.

FIG. 11 shows an alternative embodiment of the side walls. In this case, the short side wall 3 '"connecting elements 100 in the manner of a dovetail, which engage in inverse recesses 101 in the long side wall 2'". Due to the configuration of the connecting elements 100 or recesses 101, the side walls 2 '", 3'" in a direction parallel to the short side wall 3 '"rigidly connected to each other, while the short side wall in a direction parallel to the long side wall 2'" are pivoted can, wherein the connecting elements 100 are moved out of the Aufnehmung 101 out. In this case, as shown schematically in FIG. 12, the receiving plates 9 '"are arranged in such a way that that they have a minimum distance from the short side wall 3 '", which, even in the illustrated position of the receiving plates 9'", in which a folding of the short side wall 3 '"is prevented, allows the short side wall 3'" so far pivoting out of the upright position so that the connecting elements 100 are disengaged from the recesses 101 of the long side wall 2 '. "If the engagement is canceled, the long side walls 2'" may extend slightly outwards, ie away from the short side wall, be pivoted so that the gaps between the long 2 '"and the short 3'" side walls are so wide that the short side wall 3 '"on the long side walls 2'" applied receiving plates 9 '"over in the folded position can be pivoted.
