DESCRIPTION:
BRIEF SUMMARY
The invention relates to a container for the loading of bulk materials, such as construction debris, rubbish, industrial waste and the like which, for purposes of interstackability, displays outward slanting sides and glide elements enabling it to slide fully supported along the upper longitudinal edges of the container immediately below it in the stack, which edges function as longitudinal guides.
Containers of the above-described kind have been disclosed in the German Patent Specification No. 25 07 481. Such containers are customarily set up at the side where the corresponding bulk materials are generated. Resulting bulk materials are collected in the containers and, as soon as the container is filled, it can be removed by the appropriate vehicles. Generally, trucks are used for such container removal. They are equipped with devices which are also known under the designation of sliding lift-on lift-off bulk container tipper vehicles. These containers known in the art, as disclosed in Patent Specification No. 25 07 481, offer the advantage that, with the aid of such sliding lift-on lift-off bulk container tipper vehicles currently in use, they can be nested one inside the other and loaded onto trucks in stacks. The interstackability of the empty containers results in economic advantages in the storage of the empty containers and, primarily, in the transporting of the empty containers to their delivery site.
So that these containers known in the art can even be nested one inside the other they exhibit outward slanted walls. This results in the bottom surface area of a container being smaller than the area encompassed by the upper edges of that container. However, once these containers are filled, they can no longer be nested one into the other in stack formation. Consequently, the economic advantages to be derived from stacking with regard to container storage and transport, can no longer be achieved when the containers are filled. Every filled container must be individually transported and requires, for the period of its storage until the final point of unloading, that physical space occupied by it.
The object of the invention is to configure containers of the kind identified in Patent No. 25 07 481 in such a way that they can also be stacked when they are filled.
This object is accomplished by the invention in that, to achieve this additional interstackability, glide elements, adjustable with respect to position, have been provided on the container in such a way that when in their end position in the lower section of the container they are positioned over the respective longitudinal edge of the container located immediately below it in the stack. The glide elements provided to achieve this additional interstackability can be mounted on the container, in which case they are folded out, slid out, pivoted out, or the like, into their end position enabling interstacking. The adjustable glide elements may be additional glide elements located in the lower section of the container, that is, there are also glide elements for the purpose of interstackability, such that empty containers can be interstacked, as before, and which, through adjustment of the corresponding glide elements to their end position, can also be interstacked when they are filled.
The additional glide elements enabling interstackability may also be separately connected to the containers and are only then inserted into the corresponding receptacle components whenever the filled containers are to be stacked on top of each other.
It is also possible--and this has been provided for in the container configuration according to the invention--to make the existing glide elements already used to enable interstackability adjustable with respect to position in such a way that shifted into the aforementioned lower end position to enable the additional interstackability.
Two respective glide elements, positioned one behind the other, to be supported on a respective longitudinal edge have been provided for the purpose of achieving sure interstackability of
