Abstract
Abstract The coupling of two plate-shaped elements be means of an interlocking arrangement formed along the edges of the elements. The locking members of one element are in resilient engagement with identical locking members on the other element, the thickness of the individual locking members being half the thickness of the element and the members being staggered alternately to one side and the other of a plane through the center of the edge parallel to the side faces of the element.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
112 words
An interlocking arrangement for coupling two plate-shaped elements together along one edge thereof, said arrangement comprising a plurality of substantially identical locking members disposed along one edge of each element extending an equal distance from said edge and staggered alternately to one side and the other with respect to a common plane located between and extending parallel to the side faces of the element, the arrangement of said locking members being such that, in a pair of assembled plate elements, the surface of each locking member of one element facing the common plane will resiliently abut and be frictionally held against a corresponding surface of a locking member of the other element.
Claim 2
Dependent Claim
112 words
An interlocking arrangement for coupling two plate-shaped elements together along one edge thereof, said arrangement comprising a plurality of substantially identical locking members disposed along one edge of each element extending an equal distance from said edge and staggered alternately to one side and the other with respect to a common plane located between and extending parallel to the side faces of the element, the arrangement of said locking members being such that, in a pair of assembled plate elements, the surface of each locking member of one element facing the common plane will resiliently abut and be frictionally held against a corresponding surface of a locking member of the other element.
Claim 3
Dependent Claim
59 words
An interlocking arrangement as claimed in claim 1, in which the surface of each locking member facing the said common plane is slightly inclined relatively thereto, so as to gradually increase the thickness of the locking members towards the element, and is provided with a bead at one end and a groove at the other end of said surface.
