DE1951053B2 - Stackable and nestable transport box - Google Patents

Description

The invention relates to a stackable and nestable transport box with a rectangular Base area, obtuse angled to this inclined side surfaces of the same height and one as vertical Frame formed, in a plane encircling the upper edge of the box, parallel to the Lying long sides, wire-like support members are mounted on the front sides in the frame, which are made from pivot a box position releasing the box opening into a stacking position extending through it and rest on the frame in the stacking position.

Such a transport box is already known (US Pat. No. 2,864,530). The stacking up this transport box is made possible by the fact that the wire-like support members arranged outside be pivoted upwards and inwards over the longitudinal edge of the container, until they rest with their end sections on the front edge of the container. Take action in this situation the otherwise free opening of the transport box, so that another box is placed on it can be, with runner rails running along the length for its locking on its lower standing surface are upset. The support members are introduced into the container stand from the outside and inside the same U-shaped angled to pull out the hooked ends when loaded impede. In both end faces elongated openings are made below the box edge, which serve as handles.

The forehead openings below the edge of the box inevitably reduce the maximum filling height for the known transport box, and the swiveled outwards when a large number of transport boxes are nested in one another Slützglieder contain additional hazards for the stack of boxes and require larger ones Space required when storing the boxes in several close stacking rows. Because the individual Boxes when stacked on top of each other, due to the support elements lying above the edge of the box, not interlock at least partially in the area of the box edge, additional runner rails are required, which are used to lock the boxes on top of each other, but which are technically manufacturing mean extra work.

There is also a stackable transport container

ίο inclined side walls known, the upper edge of the container is stiffened, and to which downward spacers are attached, which into the The inside of the container can be folded in (German utility model 1 692 793). The known The container is beveled like a roof towards the end faces, so that it is at a lower level end up being the middle area of the long sides. Here, too, wire-like support elements come into play Application that can be pivoted in the edge area,

and that are mounted on the longitudinal side of the container, and the inside of the same from a container opening completely releasing position can be pivoted into such a stacking allows several similar containers. In the case of the transport container designed in this way slide rails must be provided along the floor surface, which have an unlimited amount of space The aim is to prevent stacked containers from shifting. The sliding rails that must be provided are disadvantageous in that this not only results in the production of such transport containers Make it costly through additional work steps, it also results in cleaning of the container unfavorable, poorly accessible edge areas, and when placing the container with Floor rails on soft supports, there is a risk that they can be depressed as a result. When setting up the known transport container already produced by the non-cutting deformation

4.0 - for example at workplaces in companies the individual parts located in it between the storage area and the container base if they are carelessly removed slip and thus only recovered by lifting the container for the ongoing work process will. It is also particularly disadvantageous in the case of the known containers that they are perpendicular to them above approaches for their lateral guidance when stacking are required, the as small-area elevations to damage the floor area, particularly heavily filled, placed on top Can lead container. The support members provided along the narrow-sided end faces are, as a result of this attachment, not infrequently confused with handles, so that they are not only from correspondingly strong metal of relatively good quality are to be manufactured in order to reduce the risk of bending escape, but must also be stored stably within the container wall.

The invention is based on the object of providing a transport box of the type mentioned at the beginning create, both with uiivcrutschbar guided Stacking a large number of transport boxes on top of each other without additional guide and locking elements as is the case with densely nested stacks of boxes without considerable empty space between the box bottoms Easily accessible cut-outs on the front as a means of accessing individual items Has transport boxes.
