Abstract

Claims (21)

1 . Element of damping layer for flooring, the element comprising:

a frame which forms a first face of said element, said frame comprising a plurality of through openings;

a plurality of support bodies which protrude from said frame at opposite side with respect to said first face, each support body being arranged at a respective through opening of said plurality of through openings and bridging with structural continuity two attachment regions belonging to said frame and mutually opposite with respect to said respective through opening,

wherein said frame has a reticular structure comprising elongated elements connected to each other at nodes,

wherein said two attachment regions are arranged mutually opposite along a longitudinal direction,

wherein each support body is attached to said frame only at said two attachment regions,

wherein each through opening is delimited by said two attachment regions and by two respective frame portions joining said two attachment regions respectively at opposite sides of said through opening,

and wherein each frame portion at least partially comprises at least two elongated elements not mutually parallel, wherein at least one of the two elongated elements has development at least partially not parallel to said longitudinal direction.

2 . Element according to claim 1 , wherein each frame portion comprises in their entirety said at least two elongated elements, wherein each of said at least two elongated elements has development at least partially not parallel to said longitudinal direction and not parallel, not even substantially, to a transversal direction substantially perpendicular to said longitudinal direction, and wherein said at least two elongated elements of each frame portion are mutually consecutive.

3 . Element according to claim 2 , wherein said at least two elongated elements have rectilinear development and define between them a connection angle facing towards the respective through opening, wherein said connection angle is greater than or equal to 90° and less than or equal to 170°.

4 . Element according to claim 2 , wherein said frame develops substantially on a plane comprising the longitudinal direction and a transversal direction substantially perpendicular to said longitudinal direction, wherein said reticular structure is regular, wherein each node is a connection point between at least three elongated elements, wherein each elongated element is straight, wherein each through opening has, a hexagonal shape having a longitudinal axis of symmetry and a transversal axis of symmetry, wherein said hexagonal shape has main development along the longitudinal direction, wherein each through opening is delimited by two first elongated elements with substantially transversal development and respectively comprising said two attachment regions, and by two pairs of consecutive second elongated elements, each pair connecting said two first elongated elements at opposite sides of the through opening, wherein each first elongated element has two transversal end portions left free by the respective attachment region, wherein said at least two elongated elements coincide with said second elongated elements, and wherein each frame portion comprises in their entirety only said at least two elongated elements and further comprises a respective transversal end portion of the two first elongated elements.

5 . Element according to claim 1 , wherein each through opening is associated with one and only one respective support body, wherein said through openings are all equal to each other and said support bodies arc all equal to each other, wherein each support body has a main development along said longitudinal direction and comprises two end portions respectively adjacent to said attachment regions, wherein at least one of, or both, said end portions of the support body has/have a transversely tapered shape, at least moving longitudinally from the support body to the frame, wherein each of one or more support bodies comprises one or more respective through openings, preferably longitudinally elongated, wherein each of one or more support bodies comprises one or more respective ribs, preferably arranged on one face of the respective support body facing towards said frame, and wherein said one or more respective ribs develop substantially parallel to a main development of the respective support body.

6 . Element according to claim 1 , wherein each support body comprises two end portions respectively adjacent to said attachment regions, wherein, in a vertical plane perpendicular to said first face and comprising the longitudinal direction, each end portion of each support body forms, together with said first face of the frame at the respective attachment region, a respective attachment angle facing towards the respective support body, said attachment angle being greater than or equal to 0° and less than or equal to 45°, preferably less than or equal to 30°, and wherein, in said vertical plane, each support body has an arc development between the two attachment regions, preferably with concavity facing towards said frame for at least part of the arc development.

7 . Element according to claim 6 , wherein each support body, in said vertical plane, has sinusoidal development with attachment angle equal to 0°.

8 . Element according to claim 1 , wherein said plurality of support bodies comprises at least a first and a second group of support bodies, each group comprising a respective plurality of rows of support bodies, wherein the rows of the first group are interspersed with the rows of the second group along a transversal direction substantially perpendicular to said longitudinal direction, wherein the support bodies of the first group are arranged staggered with respect to the support bodies of the second group with respect to said longitudinal direction by a longitudinal offset equal to substantially half of a longitudinal length of the support bodies, and wherein the support bodies of each row are all aligned to each other with respect to the transversal direction.

9 . Damping layer for flooring comprising a plurality of elements of damping layer according to claim 1 , arranged side by side.

10 . Flooring comprising:

a compact substrate;

a surface layer arranged over the substrate and

a damping layer for flooring according to claim 9 interposed between the substrate and the surface layer, wherein said first face of each element of damping layer faces towards said surface layer,

wherein said surface layer comprises a synthetic turf mat and a granular infill.
