Abstract
Abstract The invention relates to resilient or elastic floors comprising an upper floor supported on a resilient means lying on a support. Said resilient means is built up from a lower layer of resilient elements positioned on the support, an intermediate floor positioned on said lower layer, and an upper layer of resilient elements positioned on the intermediate floor and supporting said upper floor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
A resilient floor, for use in gymnastic and athletic establishments, comprising an upper floor, a resilient structure for supporting said floor and a rigid support beneath said resilient structure for supporting same, said resilient structure comprising at least one lower layer of a plurality of resilient, independent, studlike elements supported by said rigid support and spaced from each other and distributed thereon in a spaced square formation, a diaphragm arranged on said lower layer of resilient elements and spaced uniformly from said rigid support, at least one upper layer of a plurality of resilient, independent, studlike elements arranged on said diaphragm and spaced from each other and distributed thereon in spaced squared formation and displaced relative to said resilient elements of the lower layer so that each upper element lies in the center of the square formed by the lower resilient elements when viewed in plan and a plurality of planar means, said resilient elements being attached thereto in the desired spaced relation to facilitate the positioning of the elements when erecting the floor, said upper floor resting on said upper layer of resilient elements.
Claim 2
Dependent Claim
185 words
A resilient floor, for use in gymnastic and athletic establishments, comprising an upper floor, a resilient structure for supporting said floor and a rigid support beneath said resilient structure for supporting same, said resilient structure comprising at least one lower layer of a plurality of resilient, independent, studlike elements supported by said rigid support and spaced from each other and distributed thereon in a spaced square formation, a diaphragm arranged on said lower layer of resilient elements and spaced uniformly from said rigid support, at least one upper layer of a plurality of resilient, independent, studlike elements arranged on said diaphragm and spaced from each other and distributed thereon in spaced squared formation and displaced relative to said resilient elements of the lower layer so that each upper element lies in the center of the square formed by the lower resilient elements when viewed in plan and a plurality of planar means, said resilient elements being attached thereto in the desired spaced relation to facilitate the positioning of the elements when erecting the floor, said upper floor resting on said upper layer of resilient elements.
Claim 3
Dependent Claim
35 words
A resilient floor according to claim 1, wherein said planar means to which said resilient elements are attached are in turn attached to opposite sides of said diaphragm with the resilient elements extending outwardly therefrom.
Claim 4
Dependent Claim
16 words
A resilient floor according to claim 1 wherein said resilient studlike elements are composed of cork.
Claim 5
Dependent Claim
17 words
A resilient floor according to claim 1, wherein said resilient studlike elements are composed of resilient plastic.
Claim 6
Dependent Claim
17 words
A resilient floor according to claim 1 wherein said diaphragm is composed of a composite wood sheet.
Claim 7
Dependent Claim
28 words
A resilient floor according to claim 5 wherein said diaphragm is composed of a plurality of coplanar sheets and further comprising means attaching the sheets in coplanar relation.
