Abstract
Abstract A set of structural elements for producing cupboard walls, cabinets, drawers, partitions and similar wall units, which includes pairs of first plate units and second plate units. The plates of each of the plate units can be arranged so that their plate units are in alignment with each other in such a way that one edge of one unit faces the adjacent edge of the other unit of one and the same type of plate units. Connecting members respectively connect the pairs of the first plate units to the pairs of the second plate units.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A kit of interrelated component structural elements for quickly producing cupboard wall units, cabinet units, drawers, partitions, shelving and similar wall units, which includes in combination: a pair of first plate means adapted to be arranged in alignment with each other so that one edge of one of said first plate means faces a corresponding edge of the other one of said first plate means, each of said first plate means being provided with a groove, second plate means adapted to be arranged solidly at a substantially right angle to said first plate means, and strips connected to said second plate means and positively engageable with said grooves and operable to interconnect said first and second plate means, each of said strips being T-shaped metallic profiled semi-finished elements having edges located opposite to each other and set back within the region of the ends of said elements up to the extent of the thickness of the respective plate means.

Claim 3
Dependent Claim
145 words
A kit comprising structural component elements including panels having edges of equal length, first elements each having a groove in one edge, said groove extending less than the length of said edge so that it does not extend through adjoining edges, second elements each having a strip fixed along one edge, said strip being wider than the thickness of the element between its ends with the wider portion shorter than the length of said edge and equal to the length of the grooves in said first elements, said grooves being twice as wide as the thickness of said strips, so that a first element with a groove along one edge may receive the wider portions of two strips on two second elements to connect said elements, with said groove and wide portions of said strips being confined within the adjoining edges of the first element.
Claim 4
Dependent Claim
145 words
A kit comprising structural component elements including panels having edges of equal length, first elements each having a groove in one edge, said groove extending less than the length of said edge so that it does not extend through adjoining edges, second elements each having a strip fixed along one edge, said strip being wider than the thickness of the element between its ends with the wider portion shorter than the length of said edge and equal to the length of the grooves in said first elements, said grooves being twice as wide as the thickness of said strips, so that a first element with a groove along one edge may receive the wider portions of two strips on two second elements to connect said elements, with said groove and wide portions of said strips being confined within the adjoining edges of the first element.
Claim 5
Dependent Claim
73 words
A kit as claimed in claim 2, in which the strips on said second elements are provided with wide portions extending beyond both surfaces of said second elements so that two of said first elements may be connected to two of said second elements, with said first elements at right angles to said second elements and said wide portions on opposite sides of said second elements engaging in grooves in the first elements.
