Abstract
Abstract Elastic elements which can be connected together to form a flooring covering include a rectangular plastic frame, interconnected struts within the frame forming a lattice structure, male couplings in the form of elongated bars extending outwardly of the frame and having end plates, and female couplings in the form of spring latches inside the frame to connect with the elongated bars of adjacent elements. Springs extending outwardly of the frame contact an adjacent element to maintain a predetermined spacing therebetween, while the latches of female couplings contact the stop plates of cooperating male couplings to limit separation of the adjacent elements.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
An elastic, one-piece flooring element which comprises a rectangular frame, strut means forming a lattice within said frame, said frame and said strut means defining upper and lower surfaces of said flooring element, male coupling means in the form of elongated bars extending outwardly from at least one side of said rectangular frame, each said elongated bar including a stop means at an end thereof remote from said frame, female coupling means in the form of spaced apart latches located within said frame on a side thereof having no male coupling means, said latches being cooperable with a male coupling means of an adjacent said flooring element to connect said elements together, and spring means extending outwardly of said frame to contact an adjacent said flooring element to maintain a predetermined spacing therebetween.
Claim 2
Dependent Claim
133 words
An elastic, one-piece flooring element which comprises a rectangular frame, strut means forming a lattice within said frame, said frame and said strut means defining upper and lower surfaces of said flooring element, male coupling means in the form of elongated bars extending outwardly from at least one side of said rectangular frame, each said elongated bar including a stop means at an end thereof remote from said frame, female coupling means in the form of spaced apart latches located within said frame on a side thereof having no male coupling means, said latches being cooperable with a male coupling means of an adjacent said flooring element to connect said elements together, and spring means extending outwardly of said frame to contact an adjacent said flooring element to maintain a predetermined spacing therebetween.
Claim 3
Dependent Claim
17 words
An elastic, one-piece flooring element according to claim 1, wherein each said stop means comprises a plate.
Claim 4
Dependent Claim
24 words

Claim 5
Dependent Claim
35 words
An elastic, one-piece flooring element according to claim 3, wherein the latches of each female coupling means include facing support shoulders for latching a cross-piece of an elongated bar of an adjacent said flooring element.
Claim 6
Dependent Claim
42 words
An elastic, one-piece flooring element according to claim 1, where a said spring means is located between adjacent male coupling means, a stop means of each elongated bar abutting said latches of a female coupling means of an adjacent said flooring element.
