Abstract

A system for producing three-dimensional structures, especially shelving with preferably vertical uprights to which structural components, especially shelves, are releasably attachable, in which the uprights pass through drillings or recesses in the structural components. There are connecting inserts which can be arranged in the region of a drilling or recess in a structural component and secured to the latter via the uprights.

Claims

1. A construction system for building three-dimensional structures, having shelves with vertical supports, to which construction members are releasably secured, wherein the supports extend through bores or openings in the construction members, and wherein there is provided separate connecting inserts which can each be previously inserted in the region of a bore or opening in said construction members, said separate connecting inserts connecting the supports to the construction members, wherein the vertical supports comprise bars and separate spacer sleeves which can be pushed thereon, wherein the bars extend through the connecting inserts and the separate spacer sleeves are arranged between the construction members and are supported at the connecting inserts, the separate spacer sleeves of the supports having ends which are of a taperingly reduced configuration on the outside and;

wherein the connecting inserts include receiving means comprising an inside surface having a taper with an orientation which is complementary to said taperingly reduced configuration of said separate spacer sleeves whereby the separate spacer sleeves and the connecting inserts are frictionally fitted together.

2. A construction system as set forth in claim 1 characterized in that the connecting inserts project beyond the respective construction members and comprise a lateral holding guide means for support.

3. A construction system as set forth in claim 1 characterized in that the connecting inserts have flanged abutments at the inside, which limit the depth of insertion of the spacer sleeves thereof.

4. A construction system as set forth in claim 1 characterized in that the connecting inserts comprise plastic material and are produced by an injection molding process.
