Definitions
- the invention relates to a folding box which comprises a rigid floor and rigid side walls, the side walls being articulatedly connected to the floor by means of articulated devices, so that they lie parallel to the floor in a stowed position and are essentially perpendicular to the floor in a use position and a storage space define, wherein corners of at least two opposite sides are connected to each other tensile.
- sacks can be used to transport both solid and liquid ingredients. Since sack-like transport devices do not have a fixed, defined shape, orderly transport of, for example, fixed transport goods is necessary hardly possible. Furthermore, the transported ingredients are loaded differently, since the shape of the transport device results in an unordered stacking of the contents, which poses problems under certain conditions. Without content, sack-like transport devices have only a very small volume and thus have space-saving storage properties.
- Folding boxes according to the preamble of claim 1 are also known and are only suitable for the transport of solid materials. Although a conversion into a space-saving storage variant is possible by collapsing the box, such an embodiment can only be loaded with a heavy load to a limited extent without the construction being made more expensive and with greater manufacturing effort in such a way that it increases in weight and thus general usage properties such as worsening manageability.
- the invention is based on the object of demonstrating a simply constructed folding box which enables a wide range of applications with high stability.
- the folding box comprises a rigid floor and rigid side walls, the side walls being articulated to the floor via articulated devices so that they are parallel to the floor in a stowed position and are essentially perpendicular to the floor in a use position and define a storage space in which the corners of opposite sides are tensile together who are connected.
- the side walls lie in the same plane as the floor and are connected to the side walls with one another via the folding corners in such a way that they form an uninterrupted surface together with the floor, fastening devices of such a detachable design being attached to the corners of the opposite side walls, that the fastening devices are open in the stowed position and the fastening devices for tensile connection of the corners are closed in the use position.
- An essential point of the invention lies in the fact that the folding box consists of a single surface section which can be held in this state by simple fastening devices after being folded together to form the box.
- a well-known problem of folding hinges is the high mechanical stress up to the complete loss of function, especially when the carrying devices equipped with such a mechanism are used for a longer period of time to transport heavier loads.
- the joint devices are designed as film hinges or the like elastic surface sections. This makes it possible to dispense with folding hinges or the like, which are more expensive and complex to manufacture.
- the use of film hinges in the articulation devices can ensure that hazardous ingredients can be transported in solid or fluid form (e.g. acidic or basic liquids) that damage materials that are susceptible to corrosion - such as metal - and thus greatly reduce the service life ,
- Fastening devices are therefore preferably connected to the corners of the side walls via the folding corners. This ensures that after folding the side walls together with the fastening devices can connect tensile strength over the entire height of the side walls and thus receives a stable support structure that ensures that the folding box remains stable and reliable during the entire period of use.
- a disadvantage of other known carrying devices is that corresponding handles are either not available at all or are arranged as an additional element on the outside, which means that this solution requires higher manufacturing costs and more space when stacking, since protruding handles and holders provide additional storage space take in.
- Fastening devices are therefore preferably designed as handles. It is thereby achieved that when the folding box is folded up, the fastening device fulfills a double function in that it becomes a carrying handle at the same time and has no additional space requirement, for example due to protruding or protruding from the side wall of the carrying device.
- the known folding boxes have the disadvantage that they cannot be used on both sides and that it is also impossible to open the folding construction.
- conventional folding boxes can only be assigned a single usage position.
- the articulation devices and the folding corners are preferably designed such that they can be folded in two directions from an extended position in the stowed position into an angled position in the use position, so that use of the base and the side walls on the inside and outside is possible. This ensures that the folding box can be used on both sides and so, for example, by simply turning the sides, the dirty side can be turned outside and a clean user surface is available without cleaning.
- the folding box can only be closed or opened on one side. This opens up new applications, such as a shovel or shovel.
- the known support structures have no different usable surfaces, which can then be used according to the application. Only one surface is available at a time.
- the bottom and the side walls are preferably provided with two different types of surface. This results in a much broader range of applications for the user, since he can selectively select the most practical surface for his application. Thanks to their constructive solution to the moving parts - such as those of the hinged hinges - the known folding boxes have no possibility of drip-tight absorption of liquids.
- the side walls, the floor and the articulation devices are therefore preferably designed to be watertight in such a way that the storage space is watertight. This ensures that when using at least one-sided use, for example, a PVC tarpaulin as the surface, the supporting structure is such that, in addition to solid materials, fluid contents - such as water - can be transported without problems.
- a lack of stability and the resulting low transportable loads are a known problem with folding boxes.
- the known constructions have to be reinforced.
- expensive manufacturing costs and a higher dead weight have to be accepted.
- the bottom and the side walls therefore preferably contain reinforcing bodies which are coated on at least one side. This ensures a very high level of stability for the storage space - with a low empty weight of the folding box - which makes it easy to transport high loads.
- the surface therefore preferably comprises at least two web-shaped cover layers, the two web-shaped cover layers preferably being connected to one another at least in sections, preferably being integrally connected to one another by high-frequency welding.
- High-frequency welding creates a connection that is very hard-wearing and has a long service life.
- the high-frequency welding allows the same or different cover layers to be combined with one another in such a way that a tailor-made cover layer combination or laminate corresponding to the application profile can be created.
- the known support structures have the disadvantage that the user surface can often only be cleaned with difficulty. For example, corners and recessed reinforcement elements often represent problem areas in which contamination can easily occur.
- the uninterrupted surfaces can preferably be washed off on at least one side. This ensures that the smooth and washable side or sides can be cleaned very easily and easily of dirt, especially when the folding box is opened and a flat surface is created, in which cleaning is considerably simplified. Especially when transporting food and perishable goods, these are the decisive criteria for using the folding box.
- the folding box When using a correspondingly rough material as the underside, the folding box has non-slip properties and thus enables greater safety in use and ease of use.
- a disadvantage of the known folding boxes is that the resulting weight load on the carrying device during the transport of ingredients is predominantly picked up selectively, for example by means of folding hinges and similar devices, and thus quickly leads to material fatigue. This contributes to a significant reduction in the lifespan.
- the fastening devices preferably comprise straps, which preferably extend as a parallel extension of edges of the side walls, which are essentially connected to the cover layers by welding or gluing, in particular are fastened in the folding corners between the two cover layers.
- Such belts are available as standard goods by the meter and can therefore be installed inexpensively and at the same time ensure high strength.
- the tension exerted by the straps of the fastening devices on the side walls is distributed over their entire height, which in turn increases the tensile strength in a structurally simple manner.
- the known folding boxes have the disadvantage that there are no fastening devices of this type in which, in the correspondingly opened or unfolded state, a closure is provided which secures the use position by means of releasable closures.
- the fastening devices preferably comprise snap locks or similar devices.
- the fastening devices can be extremely simple, for example as a knot between the belts.
- the folding box becomes particularly easy to use if the snap locks mentioned or similarly easy-to-open devices are provided.
- a disadvantage of known support structures is that they consist of a single material - such as metal or plastic - throughout. When transporting and resting such support structures on a surface with a smooth surface - such as tiles or parquet - the carrying device can easily slip or scratch the surface.
- the floor and the side walls are therefore preferably designed to be non-slip.
- the bottom of the folding box can be made of any suitable material.
- the bottom and the side walls are designed to be non-slip, so that e.g. in a motor vehicle even when braking, the folding box remains in place. If the folding box is folded the other way round (with the non-slip bottom and the non-slip side walls facing inwards, into the storage space), objects to be transported remain in place in the folding box even during shaking transport.
- the folding corners are preferably elastic and include film hinges. It is thereby achieved that one can do without such constructions, which consist of several parts, in the mechanically particularly stressed joint and folding mechanisms of the carrying device. This construction is particularly simple and without stiff deposits.
- the folding corners are preferably elastic, that is to say without stiff inserts, and comprise film hinges. This construction is particularly simple.
- a known problem with carrying devices is that there are no possibilities for dividing the storage space in such a way that an orderly transport of several small objects, for example, is possible. This means that there is always a risk that the contents will be damaged during transport.
- foldable inserts for dividing the storage space are available. Objects to be transported can thereby be kept separate from one another and falling and slipping can be avoided.
- a known problem with carrying devices is the transport of fluid contents, since even a little carelessness on the part of the user or due to the mechanical influence of third parties can cause part of the contents - for example water or paint - to be lost. The liquid escaping from the carrying device can then cause consequential damage, such as contamination.
- the foldable inserts mentioned have a lattice structure for forming mutually communicating chambers through which the storage space is divided. With such a lattice structure, which in turn is held in place by a corresponding adjustment in the storage space, liquid can be transported in the folding box without causing sloshing or overflowing during transport.
- a known problem with filled carrying devices is their stackability. If more than one box is stacked on top of one another, the boxes slide very easily, since the devices fixing the boxes, such as grooves, are too small to withstand mechanical loads from the outside. Depending on the stack height and content of the carrying device, this can be a safety risk for the user.
- stack supports are preferably provided which are designed and can be inserted into corners of the folding box in such a way that they stand on the floor with a lower end and another corner box can be placed on their upper end.
- these supports which are more or less stable or solid in accordance with the weight to be carried, the weight of an upper folding box is guided exclusively over the stacking supports to the bottom of the lowest folding box, so that only a shear load is exerted on the stacking supports.
- the stacking supports at least at their upper edges with the side walls of the folding box in a fixed th plug-in connection. Then the stack supports are connected to one another via a frame consisting of the side walls, so that overall a kind of “lattice structure” is created.
- FIG. 2 is a schematic wedge-section illustration of the arrangement according to FIG. 1,
- Fig. 7 is a partial plan view similar to that of FIG. 6 of the folding box in the use position.
- Fig. 8 is a perspective view of a stack support.
- Fig. 1 the folding box is shown in the stowed position, in which all parts lie in a single plane.
- a floor 10 with four side walls 11, 12, 13 and 14 is connected in one piece, the side walls 11-14 being connected to the floor 10 via floor joints 20, 21, 22, 23.
- Folding corners 30, 31, 32, 33 are located between the side walls 11-14 and are connected to the side walls 11-14 via side wall joints 15, 15 ', 16, 16', 17, 17 ', 18, 18'.
- Diagonally through the fold-in Diagonal joints 34, 35, 36, 37 are attached in the folding corners 30-33 to corners facing outwards.
- straps 51, 51 'and 53, 53' protrude from the folding corners 30-33, which have snap fasteners 52, 52 'and 54, 54' at their ends and form fastening devices 50, 50 'and 55, 55'.
- the snap locks 52, 52 'and 54, 54' can be connected to one another by a snap mechanism known per se and released again by pressing a button.
- the base 10 and (all) side walls 11-14 are constructed in multiple layers. They each comprise reinforcing bodies 24, 25, 26, 27 and 28, which are attached between two cover layers 60, 62.
- the attachment can be carried out as in a bag, but the stability increases if a firm connection is provided between the cover layers 60, 62 and the reinforcing bodies 24-28.
- Arrangements in which the reinforcing bodies are connected to the cover layers by high-frequency welding are particularly durable and easy to manufacture.
- the joints 15-18, 20-23 and 34-37 are formed by welds indicated in FIG. 2, on which the material becomes essentially homogeneous after welding and is particularly flexible.
- FIG. 3 The assembly of a folding box constructed in this way is described below.
- the side walls 12 and 14 shown in FIG. 1 are folded upwards relative to the floor 10, so that the joints 17 ', 20 and 15 or 17, 22 and 15' are angled by 90 degrees.
- the side walls 11 and 13 (with the joints 18 ', 21, 16 or 18, 23 and 16' angled) are folded up in such a way that the diagonal joints 34-37 of the folding corners 30-33 are outward.
- the mutually opposite fastening devices 50 and 50 'or 55, 55' are then connected to one another, so that the side walls 12 and 14 are connected to one another in a tensile manner at their upper corners.
- the position of use thus achieved is shown in FIG. 3.
- the fastening devices 50 and 55 can be glued or sewn on, but it is particularly advantageous if the fastening devices or their belts 51, 53 are welded between the two cover layers 60, 62, as shown in FIG. 4.
- This figure also shows that the snap locks 52, 54 can be elongated in such a way that they can be used as handles.
- the two cover layers 60, 62 are provided with different surfaces 61 and 63, respectively.
- the surface 61 is designed here as a smooth, preferably chemical-resistant (solvent-resistant) surface, while the other surface 63 is formed like a felt.
- the surfaces can be folded in both directions (in Fig. 1 from the paper plane or into it), the resulting storage space 9 can either (for example for transporting dirty or wet objects) are formed by the smooth, chemical-resistant surface 61, so that the felt-like surface 63 enables the non-slip stand of the folding box. Or, you fold the box the other way around, so that the felt-like surface 63 forms the inner surface of the storage space 9, which ensures that objects placed on this surface do not slip inside the folding box and are otherwise better protected against damage.
- FIGS. 6-7 The folding process is shown again schematically in FIGS. 6-7, the upper right corner in FIG. 1 and the right corner in FIG. 3 being shown in detail in this illustration.
- an insert 70 is shown in FIG. 6, which consists of longitudinal strips 71 and transverse strips 72, which are connected to one another via joints 73, so that chambers 74 are formed between two longitudinal and two transverse strips 71 and 72, respectively.
- the connection of the longitudinal strips 71 to the transverse strips 72 can be accomplished via simple slots in wall-shaped material, as is known, for example, from wine bottle packaging. If you put full folding boxes on top If others want to stack, stack supports 80, as shown in FIG. 8, are suitable for this. Such stack supports have a lower end 81 which stands on the bottom 10 of a folding box in the use position.
- An upper end 82 protrudes above the upper edge of the folding box, so that a retaining ring 83 can grip around the outer edge of the folding box on the one hand and on the other hand a next folding box with its lower edges can be used in a non-slip manner.
- the cover layers 60 and 62 are advantageously produced from commercially available tarpaulin material, as is customary for trucks.
- the reinforcement plates can be made from a wide variety of materials, hardboard being particularly suitable, since these can be bonded very well to the tarpaulin material by high-frequency welding together with hot-melt adhesive.
- the two cover layers themselves can of course also be connected to one another by high-frequency welding.
