Floor structure

Claim 2

A floor structure, particularly for use in a stall, for example a cattle stall, comprising in combination, an underfloor of a substantially rigid material having a plurality of undercut recesses, a floor lining of resilient material including elongated members each having a bottom portion in contact with said underfloor, and each including downwardly directed projections engaging said recesses in said underfloor, a top portion integral with said bottom portion in the region of said projections and having an arched part directed upwards in the zone between said projections to define with said bottom portion at least one elongated cavity.

Claim 3

A floor structure as claimed in claim 1, wherein each elongated member is an extruded strip.

Claim 4

A floor structure as claimed in claim 2, wherein each strip, viewed in cross-section, has at least two adjacent similar cavities separated by upright webs having a height which is less than that of the arched parts of the lining.

Claim 5

A floor structure as claimed in claim 2, wherein the whole surface of the floor lining viewed in longitudinal direction of said strip is arched upwards.

Claim 6

A floor structure as claimed in claim 2, wherein each strip viewed in cross-section has at least three cavities, partition walls between said cavities, said walls making an angle other than 90* with the underfloor.

Claim 7

A floor structure as claimed in claim 5, wherein the two outermost cavities have a similar cross-section, and the center cavity has an approximately triangular cross-section.

Claim 8

A floor structure as claimed in claim 2, said stalls being elongated, wherein several of said floor lining strips extend side by side on said underfloor transversely to the direction of elongation of said stalls.

Claim 9

A floor structure as claimed in claim 7, wherein said underfloor is arched transversely to the direction of elongation of said stalls.

Claim 10

A floor structure as claimed in claim 2, wherein at least one of the ends of said cavities in the floor lining strips are closed off.

Claim 11

A floor structure as claimed in claim 9, wherein there is included means for clamping together the open ends of each floor lining strip.

Claim 12

A floor structure as claimed in claim 9, wherein there are included cover elements adhered to the end face of each floor lining strip.

Claim 13

A floor structure as claimed in claim 9, wherein the underfloor material comes up against the ends of the floor lining strips.

Claim 14

A floor structure as claimed in claim 9, wherein each floor lining strip is embedded in a concrete beam of substantially the same width, the concrete extending beyond the ends of the strips and reaching the top level thereof.

Claim 15

A floor structure, particularly for use in a stall, for example an elongated cattle stall, comprising in combination, an underfloor that is arched transversely to the direction of elongation of the stall and made of a substantially rigid material having a plurality of recesses, a floor lining of resilient material including elongated, extruded strip members extending side by side on said underfloor transversely to the direction of elongation of the stall and each having a bottom portion in contact with said underfloor, and each including downwardly directed projections engaging said recesses in said underfloor, a top portion integral with said bottom portion in the region of said projections and being arched upwards in the zone between said projections to define with said bottom portion at least one elongated cavity.

Claim 16

A floor structure, particularly for use in a stall, for example an elongated cattle stall, comprising in combination, an underfloor that is arched transversely to the direction of elongation of the stall and made of a substantially rigid material having a plurality of recesses, a floor lining of resilient material including elongated, extruded strip members extending side by side on said underfloor transversely to the direction of elongation of the stall and each having a bottom portion in contact with said underfloor, and each including downwardly directed projections engaging said recesses in said underfloor, a top portion integral with said bottom portion in the region of said projections and being arched upwards in the zone between said projections to define with said bottom portion at least one elongated cavity.

Claim 17

A floor structure, particularly for use in a stall, for example a cattle stall, comprising in combination, an underfloor of a substantially rigid material having a plurality of recesses, a floor lining of resilient material Including elongated, extruded strip members each having a bottom portion in contact with said underfloor, and each including downwardly directed projections engaging said recesses in said underfloor, a top portion integral with said bottom portion in the region of said projections and being arched upwards in the zone between said projections to define with said bottom portion at least one elongated cavity, the ends of which are closed off, said underfloor being defined by a concrete beam in which said strip members are embedded, said concrete beam being of substantially the same width and extending beyond the ends of said strip members, said concrete beam reaching the top level of said strip members.

Claim 18

A floor structure, particularly for use in a stall, for example a cattle stall, comprising in combination, an underfloor of a substantially rigid material having a plurality of recesses, a floor lining of resilient material Including elongated, extruded strip members each having a bottom portion in contact with said underfloor, and each including downwardly directed projections engaging said recesses in said underfloor, a top portion integral with said bottom portion in the region of said projections and being arched upwards in the zone between said projections to define with said bottom portion at least one elongated cavity, the ends of which are closed off, said underfloor being defined by a concrete beam in which said strip members are embedded, said concrete beam being of substantially the same width and extending beyond the ends of said strip members, said concrete beam reaching the top level of said strip members.
