Abstract
Abstract The invention relates to a groundcovering element, consisting of a plurality of components (1) with links (2,3) in between, a method for the manufacture thereof and a method for the manufacture of a mold (24, 25, 26, 27, 29, 30). According to the invention it is provided that the links between the components are deformable, possibly flexible and allow for a distance between adjacent components, resulting in a groundcovering element that is easy to lay, offers better possibilities of adjustment to various desired surfaces to be covered and is considerably more suitable for a more or less undulating terrain. In a method of manufacture, one steel mold part (34) cooperates with many rubber ones (31), so that with little investment a high production rate is obtained.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
63 words
A groundcovering element comprising: a plurality of components; and links positioned between said components for providing a distance between adjacent components, said links having a curved shape for allowing the distance between adjacent components to be increased by straightening said curve or decreased by tightening said curve, said links comprising a deformable material selected from the group consisting of bendable plastic or metal.
Claim 2
Dependent Claim
63 words
A groundcovering element comprising: a plurality of components; and links positioned between said components for providing a distance between adjacent components, said links having a curved shape for allowing the distance between adjacent components to be increased by straightening said curve or decreased by tightening said curve, said links comprising a deformable material selected from the group consisting of bendable plastic or metal.
Claim 3
Dependent Claim
23 words
Groundcovering element as claimed in claim 1, in which the links are part of a deformable mesh incorporated in a plurality of components.
Claim 4
Dependent Claim
28 words
Groundcovering element as claimed in claim 1, in which the links are located at 2/3 to 1/3 of the height, measured from a bottom side of the component.
Claim 5
Dependent Claim
23 words
Groundcovering element as claimed in claim 1, in which the components have a bottom surface and the links are attached to said surface.
Claim 6
Dependent Claim
22 words
