Abstract
Abstract A floor covering ( 1 ) made of an elastically moldable material, in particular from a synthetic rubber, which is provided with a regular arrangement consisting of first projections ( 3 ) on the upper side ( 1 a ) and with a regular arrangement of second projections ( 5 ) on the underside ( 1 b ), the projections of the first projections and of the second projections not exhibiting any overlapping area on the plane of the covering and that, on the underside within the projections of the first projections, third projections ( 7 ) are provided in each case which have a smaller height vis-à-vis the second projections such that the floor covering only touches a floor with the second projections when it is in an unloaded state, however, when a preset load is exceeded locally, the third projections come in contact with the floor.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
138 words
A floor covering made of an elastically deformable material, comprising an upper side; an underside; first projections regularly arranged on the upper side; second projections regularly arranged on the underside for supporting the floor covering on a floor, the first and second projections having no overlapping regions in a plane of the floor covering; and third projections provided on the underside, arranged between the second projections, and having, in an unstressed state of the floor covering, a height smaller than a height of the second projections, whereby the third projections provide for an additional support of the floor covering on the floor when a load applied to the floor covering exceeds a predetermined value, wherein the third projections have a load dependent increasing characteristic line of rigidity whereby a progressive cushioning characteristic of the third projects is obtained.
Claim 2
Dependent Claim
138 words
A floor covering made of an elastically deformable material, comprising an upper side; an underside; first projections regularly arranged on the upper side; second projections regularly arranged on the underside for supporting the floor covering on a floor, the first and second projections having no overlapping regions in a plane of the floor covering; and third projections provided on the underside, arranged between the second projections, and having, in an unstressed state of the floor covering, a height smaller than a height of the second projections, whereby the third projections provide for an additional support of the floor covering on the floor when a load applied to the floor covering exceeds a predetermined value, wherein the third projections have a load dependent increasing characteristic line of rigidity whereby a progressive cushioning characteristic of the third projects is obtained.
Claim 3
Dependent Claim
20 words
A floor covering according to claim 1 , wherein the first projections essentially have the shape of a spherical segment.
Claim 4
Dependent Claim
31 words
A floor covering according to claim 1 , wherein at least one of the second and third projections have a shape of one of a flat square prism and a frustum.
Claim 5
Dependent Claim
37 words
A floor covering according to claim 1 , wherein the first projections are formed by superimposition of two basic geometric forms including a larger spherical segment and a smaller spherical segment mounted on the larger spherical segment.
Claim 6
Dependent Claim
32 words
A floor covering according to claim 1 , wherein at least one of the second and third projections have a shape of one of spherical segment, flat truncated cone, and flat cylinder.
Claim 7
Dependent Claim
56 words
A floor covering according to claim 3 , wherein the second projections have the shape of the one of a square prism and a frustum with rounded edges and rounded areas adjoining underside of the covering and extending to a plane of the floor covering, and the third projections have the shape of a spherical segment.
Claim 8
Dependent Claim
30 words
A floor covering according to claim 1 , wherein a distance between opposite edges of each of the second projections correspond to at least a distance between adjacent second projections.
Claim 9
Dependent Claim
29 words
A floor covering according to claim 1 , wherein a distance between opposite edges of each of the third projections is less than a distance between adjacent third projections.
Claim 10
Dependent Claim
31 words
A floor covering according to claim 8 , wherein the distance between the opposite edges each of third projections is less than ¾ of the distance between the adjacent third projections.
Claim 11
Dependent Claim
47 words
A floor covering according to claim 1 , wherein grid sizes of arrangements of the first and second projections essentially correspond, and a grid size of the third projections corresponds to the grid size of the arrangements of the first and second projections or a multiple thereof.
Claim 12
Dependent Claim
61 words
A floor covering according to claim 1 , wherein a height of the first projections is less than ⅓ of a largest dimension thereof in a covering plane and a height of at least one of a second and third projections is in a range of between ⅕ and ½ of a dimension thereof in a plane of the floor covering.
Claim 13
Dependent Claim
28 words
A floor covering according to claim 1 , further comprising at least one of perforations provided between the first and second projections and recesses formed in the underside.
Claim 14
Dependent Claim
30 words
