Abstract

The frame (12) has front walls including front wall parts (16', 16'', 16'''), which are folded by four hinge elements. The hinge elements are provided parallel to a corner axis (3). Side walls (14) are pivoted around the corner axis and a hinge axis of the front walls in an intermediate space in a position parallel to one of the side walls. Length of package of the side walls and the front walls is shorter than length of an inner space of a container so that the folded frame is completely received in the container. A horizontal stabilizing part (19) is extended parallel to a base part.

Description

The invention relates to a Aufsetzrahmen for transport containers, such as lattice boxes or lattice box transport pallets.

As a lattice box transport pallet designated containers are used for transport and in trade for the careful transport and sale of general cargo. Such lattice box transport pallets are also available as folding boxes for the purpose of reducing the return of empties.

The one-piece lattice box transport pallet according to WO 95/21773 consists mainly of a supported over foot parts bottom part and of this towering lattice walls. The front wall is formed of two pivotally connected to each other about a central horizontal axis wall parts, so that an upper part of the front wall to facilitate the loading and unloading of the lattice box is folded forward. This grid box transport pallet is closed at the top by a cooperating with the lattice walls cover and a locking bracket. This known lattice box transport pallet is suitable for transporting uniformly shaped and packaged objects, stackable articles or product packages.

From the DE-C 43 15 040 a folding lattice box transport pallet is known, which consists of a bottom frame and hinged to these connected lattice walls, wherein the lattice walls between an erect position in which the lattice box pallet can carry payload, and a folded position in which the lattice box Transport pallet can be transported as empties with low transport volume, movable back and forth and can be locked in their respective position. Although a foldability of lattice box transport pallets ensures a certain optimization in transport, but limited in terms of their use, but mainly on lattice box transport pallets, which are used to transport relatively good stackable goods.

In the DE 43 43 960 A1 a device is described for collecting packages, comprising at least one or more deployable side parts, which set up outside the collective packaging include a space for accommodating the collective packaging or set up within the collective packaging the largest possible space within the collective packaging, are surrounded by the collective packaging and a holding device , Which is connected to the one or more side parts, for securing the collective packaging on the erected side part or the erected side parts.

The DE 37 00 634 A1 proposes separate nestable pallet cradles for pallets that circulate between the supplier and the recipient. For repatriation of the Aufsetzrahmen is folded, so that the space requirements for this Aufsetzrahmen is relatively low.

DE 10051678 C2 describes a two-part lattice box transport pallet, which has a foldable tube frame, which can be transported in a folded position of the lattice box transport pallet independently and space-saving empties. This lattice box transport pallet tube frame has two rigid side walls and two each of at least two along a hinge axis against each other and to this parallel hinge axes against the side walls foldable frame members formed end walls, the side walls consist exclusively of longitudinal members, at which end to the corresponding cross members of the frame parts the end walls are hinged.

The frame parts forming the two end walls each consist of three cross-beam sections arranged one above the other, while the two side walls consist of superimposed longitudinal beams connected to the transverse beams by wing hinges. One side wall consists of two or three, the opposite of the side access opening the lattice box associated side wall, however, only two superimposed longitudinal beams. Fillings can now be used in the tube frame, which is expediently formed entirely from lengths of a square hollow-section material, and can be detachably fastened to the longitudinal or transverse bars by means of clamping.

Out DE 296 09 108 U a transport container is known, the Aufsetzrahmen has side walls which are pivotable in each corner about an axis perpendicular to the bottom of the container axis, wherein two mutually parallel side walls consist of two frame parts, which are centrally connected by a hinge. Thus, from the bottom part - eg. A pallet - removed frames are merged, with the two-part side walls superimposed. The length of the package thus folded is shorter than the clear length of the interior of the container, so that the frame can be layered in the transport container. This is achieved there by the use of locking elements 11, which are displaced along the peripheral edge away from the corner area - however, this model was not suitable for lattice boxes, especially those with an engagement flap.

These known lattice boxes were able to be improved in that they rusted easily due to metallic material for the lattice walls, were relatively heavy and in embodiments with engaging flaps also took in the collapsed state a lot of space and were difficult to transport. The metal mesh was still loud in mutual contact and difficult to clean or maintain.

It is therefore an object of the invention to avoid the disadvantages of the prior art.

The object is achieved by a transport lattice box with Aufsetzrahmen according to the features of claim 1. Advantageous developments emerge from the dependent claims.

Preferably, the stabilizing part for the Aufsetzrahmen is provided in at least an upper part of an end wall openable, extending transversely over a majority of the Stirnwandoberabschnitts removable flap, wherein after removing the flap, the side walls at the edges each about an orthogonal to the bottom extending corner axis, formed by Stand, swiveling.

It is also possible that the stabilizing part of the end wall is a removable stabilizing part extending transversely in the upper region of the end wall.

Typically, the axles in the corners of the attachment frame are formed by closed and / or open bearing tabs on the side walls through which the posts are mounted as axes of rotation and extending at the side wall edges, whereby the non-foldable side walls and foldable side walls are pivotable with respect to each other and / or closed bearing lugs in the pivoted-up position of the container are aligned with the side walls and protrude beyond them in the longitudinal direction, as well as protrude in collapsed form of the Aufsetzrahmens transversely from the side walls under support of the stand.

Preferably, the attachment frame is a pallet, such as a Euro pallet, can be placed as a bottom part, wherein at the lower marginal edges of the side walls of the Aufsetzrahmens fastening / locking means are arranged, which engage over the edges of the pallet.

Preferably, further elements are selected at the upper edge of the container arranged by locking elements, stacking elements or carrying elements, by means of which the frame is locked in the pivoted-up position / by means of which a stacking aid is formed for a patch on the mouth of the container lid or bottom or a frame of another container.

The side walls may, for example, as a flat frame with plates lattices, perforated plates or flexible sheets as filling, made of plastic or metal, be formed-but it is also possible to produce them from composite materials - for example, to work with pickled reinforcing material

It is also possible that for stabilizing the unfolded position of the Aufsetzrahmens a rigid subframe is used, which is pivotally hinged to one of the side wall edges about an axis parallel to the longitudinal axis thereof and can be locked with an opposite side wall edge.

In a preferred embodiment of the invention, the attachment frame is made essentially of plastic.

Particularly preferably, the Aufsetzrahmen part of a plastic grid box.

Especially the embodiment with plastic has the advantage - preferably for the pallet on which the Aufsetzrahmen is set, that the box transported environmentally friendly - because easier - and can be easily cleaned. It is corrosion-free and the attachment frame can be folded together so that it fits into a built-up lattice box so that it does not protrude beyond the lattice box wall.

It is easy to recycle, allows for a better freight-optimized stacking of the empties by the complete insertion of the folded Aufsetzrahmen. Until now, steel frames had to be scrapped or repaired in an expensive way, while grid frame made of thermoplastic material had to be scrapped or repaired be recycled in a simple form to the plastic recycling. The plastic is weather-resistant and easy to clean - even wet.

The invention will now be described in more detail in the following description with reference to an embodiment shown in the drawing, which is by no means limited to this embodiment, which is only illustrative.
