Abstract

Container for the loading of bulk materials, such as construction debris, rubbish, industrial waste and the like which, for purposes of interstackability, displays outwardly 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. To achieve this additonal interstackability, in particular with filled containers, glide elements, adjustable with respect to position, have been provided on the container. The guide elements are 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. Each glide element is arranged on a positioning element which is secured in adjustable, movable position on the container by a locking element mounted on the container.

Claims

1. A container for the loading of bulk materials, such as construction debris, rubbish, industrial waste and capable of interstackability and of nesting, said container comprising upper longitudinal edges;

said container having two outwardly slanting sides and having glide elements enabling it to slide supported along the upper longitudinal edges of the container immediately below it in a stack;

said upper longitudinal edges comprising longitudinal guides, said container having a lower section and an upper section;

wherein there are four glide elements with there being two respective glide elements, positioned one behind the other in a longitudinal direction, on said two outwardly slanting sides, and said glide elements are supported on said upper longitudinal edges;

four positioning adjusting elements with there being one on which each of said four glide elements is arranged;

four receptacle locking means mounted on the container with their being one for securing each of said positioning elements in an adjustable, movable position on the container, said four receptacle locking means being located with two respective receptacle means vertically positioned one behind the other in the longitudinal direction on said two outwardly slanting sides of said container; and

for achieving said interstackability, said glide elements being adjustable vertically downwardly by being provided on the container in such a way that when in their vertically downward position in the lower section of the container, the guide elements are positioned over the respective upper longitudinal edge of the container located immediately below it in the stack; and

,

for achieving nesting of said containers, said glide elements being adjustable vertically upwardly.

2. A container according to claim 1, wherein each glide element comprises a pivoted roller.

3. A container according to claim 1,

wherein the positioning element comprises a bar component movable relative to the receptacle.

4. A container according to claim 3,

wherein said receptacle has a hollow section;

and

wherein the bar component is a sectional rod within the hollow section.

5. A container according to claim 3, further comprising means for externally mounting each receptacle on the sides in the upper section of the container in an approximately perpendicular alignment.

8. A container according to claim 1,

wherein the locking element locks at least one of the end positions of the glide elements in place.

9. A container according to claim 8,

wherein each locking element comprises intercongruent bores in the bar component and in the receptacle;

and

a connector pin for plugging into the bores.

10. A container according to claim 1,

further comprising bolting down elements for securing interstacked containers during transit.

11. A container according to claim 10, wherein the bolting down elements comprise projections which protrude from the longitudinal edges into the sliding path of the glide elements, up against which projections the respective glide elements supported on these edges stop in the final stacking position;

and

at least one actuable clamping bolt.

12. A container according to claim 11, further comprising a rear projection shaped like a claw finger and protruding from the longitudinal edge;

a rear glide element supported on the respective longitudinal edge; and

said rear projection laterally and from the top engaging in hook-like fashion said rear guide element.

13. A container according to claim 11, further comprising a forward projection clasp including two blocks, with each block having sides facing away from each other and positioned one behind the other on the longitudinal edge;

said blocks accommodating a glide element between them; and

said blocks exhibiting oblique slopes on the sides facing away from each other.

14. A container according to claim 13, wherein at least one of the blocks is separately connected to the longitudinal edge.

15. A container according to claim 11:

wherein each actuable clamping bolt is shaped like an elbow lever clamp and comprises a clamping lever mounted in position on the container;

a tensioning pawl mounted on the clamping lever; and

an opposing element on the respective adjoining container in the container stack; and

said tensioning pawl capable of engaging said opposing element.

6. A container for the loading of bulk materials, such as construction debris, rubbish, and industrial waste capable of interstackability and of nesting, said container comprising upper longitudinal edges;

said container having two outwardly slanting sides and having glide elements enabling it to slide supported along the upper longitudinal edges of the container immediately below it in a stack;

said upper longitudinal edges comprising longitudinal guides, said container having a bottom;

said container bottom having sides and having a centerline;

wherein there are four glide elements with there being two respective glide elements, positioned one behind the other in a longitudinal direction on said upper longitudinal edges, and said glide elements are supported on said upper longitudinal edges;

four positioning adjusting elements with there being one on which each of said four glide elements is arranged, each positioning element is on the upper longitudinal edge;

four receptacle locking means mounted under the bottom of the container for securing each of said positioning elements in an adjustable, movable horizontal position under the bottom of the container, said four receptacle locking means being located with two respective receptacle means horizontally positioned one behind the other in the longitudinal direction on the sides of the bottom of the container;

for achieving said interstackability, said glide elements being adjustable horizontally from said bottom sides toward said bottom centerline of the container immediately above it by being provided on the container in such a way that when in their horizontal position on the upper longitudinal edges of the container, the guide elements are positioned beneath the bottom of the container located immediately above it in the stack; and

for achieving said nesting, said glide elements being adjustable horizontally from said bottom centerline of the container toward said upper longitudinal edges of the container.

7. A container according to claim 6, wherein the positioning adjusting element is located in the receptacle locking means and has an offset in its end section which faces the glide element.
