Definitions

• the invention relates to a folding container with an associated lifting device for attaching and opening the folding container, which consists of two vertically divided half-shells which are connected to one another by means of joints located in the parting plane and have hooking members projecting upwards for the lifting device. has the horizontally displaceable receiving members which can be brought into engagement with the hooking members on a suspension cross member.
• a folding container of this type is known from EP-0 143 197-Al, which is primarily designed for the disposal of waste paper.
• This known folding container therefore has hooking elements arranged on the closed container ceiling, which requires that the upper ceiling parts belonging to the folding half-shells belong to the load-bearing elements of the folding container.
• folding containers are used as waste collection containers, it is advantageous if the filling is not impeded by a cover which is closed on the top side, so that central hooking elements on the top side of the folding container cannot be used. Accordingly, this is also the case for the Known folding container provided hoist can not be used, which is matched with two straight, horizontally displaceable driver hooks to the hooking elements arranged one behind the other on the top of the folding container.
• the invention is therefore based on the object of creating a folding container of the generic type which is basically open at the top and can nevertheless be operated by means of a lifting device which has the horizontally displaceable receiving members on a suspension crossmember.
• the half-shells which form the container halves and are open at the top, make the container accessible for the insertion of waste or the like from above, so that practically the entire open top of the folding container is available as a throw-in opening stands. In principle, this does not prevent the folding container from being opened by means of a To be able to close the lid, the only decisive factor here is that a load-bearing container ceiling is eliminated. Therefore, the load-bearing hooking elements are arranged on the upper edge of the side walls running transversely to the joint axis and are thus firmly connected.
• the hoist with its receiving members in the form of the supporting beams or rods is adapted to the distance between the two opposing hooking members of a half-shell, which consequently adjusts the distance between the hanging crossbar of the hoist arranged centrally above the attached folding container and the edge hooking members on the half-shells of the Bridge the container.
• the same hoist can be used here as for those folding containers which have container ceiling elements with supporting hook members arranged on the upper sides of the half-shells. In this case, the half-shells of the folding container are unfolded for emptying by horizontal displacement of the receiving members of the lifting device and returned to the folded closed position.
• the hooking members of the two half-shells on the upper edges of the side walls articulated to one another are mirror images of hooks with mouths opening horizontally in the folded position of the half-shells.
• the receiving members of the hoist can be brought into engagement with the hooks from the outside or from the inside by horizontal displacement.
• the mutually facing arrangement of the mouths of the two mutually mirror-inverted halves is particularly useful. ken, which in this case have an upwardly angled inner section which is delimited by a vertical hook end in the folded position of the half-shells.
• the lifting members of the hoist can only be inserted into the hooks from the inside, that is to say from the side lying towards the joints, after which they have to be raised in order to fold the half-shells of the folding container away from one another, that is to say to open them.
• the drive unit can work shorter on the suspension crossmember, and there is also a certainty that the container is only opened in a hanging arrangement, that is, not when the half-shells of the container rise up and the receiving members of the hoist are accidentally moved together in a loosely suspended position.
• the hooks expediently have a support leg placed on the edge of the side walls of the half-shells, which enables the hooks to be securely attached to the side walls of the half-shells.
• this support leg serves as a wear protection element for the upper edges of the side walls of the half-shells because the receiving members of the suspension crossmember can be placed thereon before they are brought into engagement with the hooks. It is further advantageous if the support legs of the mirror-image hooks are at the same time arms of the joints connecting the half-shells, because the hooks have to be made from a high-strength material such as a suitable steel anyway.
• the hooking members or hooks are advantageous Flat parts which are arranged upright on the upper edges of the side walls essentially in their vertical alignment. This prevents disturbing protrusions both towards the inside of the container opening and towards the outside.
• the supporting rods of the hanging cross member are each provided at both ends with projecting receiving pins.
• These receiving pins have a diameter which is smaller than the opening width of the hook mouths by a clearance.
• the support pins of the support rods have enlarged securing plates at their free ends, which are larger than the lateral opening width of the hooks.
• conical inner sides are expediently provided on the securing plates of the receiving pins of the supporting rods.
• the coupling of the support rods of the suspension cross member to the hooks of the half-shells is facilitated if the locating pins are placed on stop plates at the front ends of the support rods, the distance between these stop plates being a clearance greater than the inner distance of the opposing hooks on the side walls the half-shells is.
• the known hanging trays can be used as lifting equipment for the folding container according to the invention. verses with horizontally displaceably driven catch hooks can be used, and for the combination with this the support rods have coupling pockets in the center in which the aforementioned catch hooks can be releasably fixed.
• the half-shells have walls doubled in the upper region with a lower shoulder towards the side walls and the end walls, which are aligned with their upper edges in the vertical direction. Furthermore, on the end walls of the half-shells, downwardly open recesses are arranged in the doubled walls, the outline of which is adapted to the upper envelope shape of the hooking members on the upper edges of the side walls. Accordingly, the adjacent folding containers must be rotated relative to one another in a boxed arrangement so that the hooking members of the respective lower folding container fit into the recesses in the doubled walls of the folding container arranged above them.
• the folding container according to the invention can be moved if necessary, it can be placed in the folded position of the half-shells on a chassis which has a receiving frame which encompasses the half-shells in the lower region. It is important to enclose the half-shells in the folded position so that the folding container does not open automatically. It is therefore also not possible to cast rollers immediately bar on the undersides of the bottoms of the half-shells.
• the force application points of the hooking members or the hooks on each half-shell are advantageous outside of those parallel to the division plane Center plane arranged to the division plane.
• the center of gravity of each half-shell is thus in the vertical direction on the side of the half-shells facing away from the joint, which causes a closing moment which is favored by the weight of the closed end walls of the half-shells.
• the half-shells complement one another in the collapsed position to form an essentially cubic basic shape of the folding container, which enables a space-saving arrangement of several such containers next to one another, in particular if a fractional collection of waste is carried out by means of these folding containers.
• the folding container according to the invention can therefore advantageously be used on construction sites where waste is produced from different materials. The separate storage of these materials in combination with the fact that the folding containers can be emptied in a hanging arrangement makes disposal easier and less expensive.

• the folding container 1 Since the folding container 1 must always be open at the top for filling, but on the other hand it must be attached via a hoist to open the half-shells 2, only the upper edges 5 of the side walls 4 or the upper edges are primarily for the attachment of corresponding coupling elements Edges 6 of the end walls 3 of the half-shells 2 are available.
• the swiveling axis of the half-shells 2 lies on the top of the folding container 1 in the vertical division plane, and in view of the smallest possible working stroke of the hoist, the hooking members 7 required for coupling are on the upper edges 5 of the side walls 4 of the half-shells 2 arranged near the pivot axis.
