Abstract

A new athletic floor resiliently retrofit to a worn athletic floor. The worn floor includes a plurality of elongated raised channels spaced from one another and connected to a ground substrate. The new athletic floor includes at least two elongated subfloor panels. At least two elongated raised channels are spaced from one another and have a first set of adjoined elongated subfloor panels located therebetween. At least one elongated raised channel is spaced therefrom and has a second set of adjoined elongated subfloor panels located therebetween. A resilient pad is positioned between each elongated subfloor panel and the ground substrate. A new flooring is located on the first and second sets of elongated subfloor panels, covering at least one elongated raised channel, and a bottom surface of the new flooring is spaced from a top surface of the elongated raised channel by a gap.

Dependent claims

A new athletic floor resiliently retrofit to a worn athletic floor comprising a plurality of elongated raised channels spaced from one another and connected to a ground substrate, the new athletic floor comprising:

at least two elongated subfloor panels, each elongated subfloor panel
(i) connectable to the ground substrate,
(ii) comprising opposite shiplap ends, and
(iii) adjoined to at least one other elongated subfloor panel at the opposite shiplap ends to form a first set of adjoined elongated subfloor panels;
at least two elongated raised channels spaced from one another and having the first set of adjoined elongated subfloor panels located between the two elongated raised channels spaced from one another;
at least one elongated raised channel spaced from the at least two elongated raised channels and having a second set of adjoined elongated subfloor panels located between two elongated raised channels spaced from one another;
a resilient pad positioned between a bottom surface of each elongated subfloor panel and the ground substrate;
and,
a new flooring located on the first set and the second set of elongated subfloor panels and covering at least one elongated raised channel, wherein a bottom surface of the new flooring is spaced from a top surface of the elongated raised channel by a distance of between about 2.3 millimeters and about 5 millimeters when the new flooring is in an unloaded condition.

A method to resiliently retrofit a worn athletic floor to have new wear life, the worn athletic floor comprising a plurality of elongated raised channels spaced from one another and connected to a ground substrate, comprising the steps:

adjoining at least two elongated subfloor panels to each other at opposite shiplap ends to form a first set of adjoined elongated subfloor panels;
locating the first set of adjoined elongated subfloor panels on the ground substrate between two elongated raised channels spaced from one another;
locating a second set of adjoined elongated subfloor panels on the ground substrate and between a third elongated raised channel spaced from the two elongated raised channels;
positioning a resilient pad between a bottom surface of each elongated subfloor panel and the ground substrate;
locating a new flooring on the first set of adjoined elongated subfloor panels and the second set of adjoined elongated subfloor panels and covering at least one elongated raised channel;
and
spacing a bottom surface of the new flooring from a top surface of the elongated raised channel by a distance of between about 2.3 millimeters and about 5 millimeters when the new flooring is in an unloaded condition.
