Abstract

An expansion joint profile system for producing an expansion joint in the manufacture of a rigid floor covering includes a profile ( 1 ) comprising a first profile element ( 3 ) having a first support leg ( 5 ) provided for bearing on a substrate ( 18 ) and a first abutment leg ( 6 ) projecting upwardly therefrom. A second profile element ( 4 ) has a second abutment leg ( 6 ). A connection element ( 9 ) is formed in a ridge-like manner and extends in the longitudinal direction between the two profile elements ( 3, 4 ) and connects them to one another in the lower region. An insertion opening ( 10 ) is formed between the abutment legs and is open at the top and extends in the longitudinal direction (L). A sealing element ( 11 ) is formed in a T-shaped cross-section with a downwardly projecting insertion leg ( 12 ) for insertion into the insertion opening ( 10 ).

First claim

1 . An expansion joint profile system for producing an expansion joint in the manufacture of a rigid floor covering, comprising
a profile ( 1 ) comprising a first profile element ( 3 ) made of a first material and having an L-shaped cross-section, extending in a longitudinal direction (L) and having a first support leg ( 5 ) provided for bearing on a substrate ( 18 ) and a first abutment leg ( 6 ) connected to one of the longitudinal edges of the support leg ( 5 ) and projecting upwardly therefrom, a second profile element ( 4 ) made of said first material and having a second abutment leg ( 6 ) which is formed to correspond to the first abutment leg ( 6 ) and extends in particular parallel to the first abutment leg ( 6 ), and a connection element ( 9 ) which is made of a second material having a higher elasticity than the first material, wherein the connection element ( 9 ) is formed in a ridge-like manner, extends in the longitudinal direction between the two profile elements ( 3 , 4 ), connects them to one another in the lower region and, together with the two abutment legs ( 6 ), forms an insertion opening ( 10 ) which is open at the top and extends in the longitudinal direction (L), and a sealing element ( 11 ) made of a third material having a higher elasticity than said first material, wherein the sealing element ( 11 ) extends in the longitudinal direction (L), is formed in a T-shaped cross-section with a downwardly projecting insertion leg ( 12 ) designed for insertion into the insertion opening ( 10 ) and with two laterally projecting compression legs ( 13 ), wherein the compression legs ( 13 ), when the insertion leg ( 12 ) is disposed in the insertion opening ( 10 ), project outwardly from the abutment legs ( 6 ), respectively, wherein the third material may correspond to the second material.

2 . The expansion joint profile system according to claim 1 , wherein the first material is plastic.

3 . The expansion joint profile system according to claim 1 , wherein the second material or the third material is a soft silicone or plastic material, which is resistant to fungi and bacteria.

4 . The expansion joint profile system according to claim 1 , wherein the second profile element ( 4 ) is L-shaped in cross-section and has a second support leg ( 5 ) which is provided for bearing on the substrate ( 18 ) and is connected to the lower longitudinal edge of the second support leg ( 6 ).

5 . The expansion joint profile system according to claim 4 , wherein the first support leg ( 5 ) and the second support leg ( 5 ) are provided with a plurality of through openings ( 7 ) distributed along the longitudinal direction (L).

6 . The expansion joint profile system according to claim 4 , wherein the first support leg ( 5 ) and the second support leg ( 5 ) each have a height (h) in the range from 0.5 to 2 mm.

7 . The expansion joint profile system according to claim 6 , wherein the first support leg ( 5 ) and the second support leg ( 5 ) each have a width (b) in the range from 8 to 30 mm.

8 . The expansion joint profile system according to claim 1 , wherein the abutment legs ( 6 ) each extend perpendicularly to the support leg or legs ( 5 ).

9 . The expansion joint profile system according to claim 1 , wherein the abutment legs ( 6 ) are provided with inwardly directed, longitudinally extending locking ribs ( 8 ).

10 . The expansion joint profile system according to claim 9 , wherein the insertion leg ( 12 ) is provided with outwardly projecting locking projections ( 14 ) which cooperate with the locking ribs ( 8 ).

11 . The expansion joint profile system according to claim 1 , wherein the abutment legs ( 6 ) have a substantially constant cross section in the longitudinal direction (L).

12 . The expansion joint profile system according to claim 11 , wherein the abutment legs ( 6 ) have a height (H) in the range from 4 to 30 mm.

13 . The expansion joint profile system according to claim 11 , wherein the abutment legs ( 6 ) have a width (B) in the range from 0.5 to 2 mm.

14 . The expansion joint profile system according to claim 1 , wherein the first profile element ( 3 ) and the second profile element ( 4 ) are each an extruded profile, the extruded profiles ( 4 ) being of the same cross-section.

15 . The expansion joint profile system according to claim 1 , wherein the compression legs ( 13 ) are provided with lateral recesses ( 15 ) extending in the longitudinal direction (L).

16 . The expansion joint profile system according to claim 1 , further comprising a cover element ( 2 ) that extends in the longitudinal direction (L), a width (b 1 ) of which corresponds to a distance between outer surfaces of the abutment legs ( 6 ) and which can be detachably placed on the abutment legs ( 6 ) or is connected to at least one of the abutment legs ( 6 ) in the delivery state of the expansion joint profile ( 1 ), the connection having a predetermined breaking point in order to separate the cover element ( 2 ) from the abutment leg or legs ( 6 ).

17 . The expansion joint profile system according to claim 16 , wherein the cover element ( 2 ) is made of a fourth material, which is plastic.

18 . An expansion joint profile system for producing an expansion joint in the manufacture of a rigid floor covering, comprising
a profile ( 1 ) comprising a first profile element ( 3 ) having an L-shaped cross-section, extending in a longitudinal direction (L) and having a first support leg ( 5 ) provided for bearing on a substrate ( 18 ) and a first abutment leg ( 6 ) connected to one of the longitudinal edges of the support leg ( 5 ) and projecting upwardly therefrom, a second profile element ( 4 ) having a second abutment leg ( 6 ) which is formed to correspond to the first abutment leg ( 6 ) and extends in particular parallel to the first abutment leg ( 6 ), and an elastic connection element ( 9 ) formed in a ridge-like manner, extending in the longitudinal direction between the two profile elements ( 3 , 4 ), connecting them to one another in the lower region, and an insertion opening ( 10 ) formed between the abutment legs which is open at the top and extends in the longitudinal direction (L), and a sealing element ( 11 ) made of an elastic material extending in the longitudinal direction (L), formed in a T-shaped cross-section with a downwardly projecting insertion leg ( 12 ) designed for insertion into the insertion opening ( 10 ).
