Abstract

Claims (45)

1. A track fitting assembly ( 10 ), comprising:

at least two mutually parallel tracks ( 71 , 72 ) for a sliding door system;

at least one Z-shaped carrier part ( 21 ; 22 ; 23 ) which has

a vertical leg ( 27 ),

a fastening leg ( 24 ) extending horizontally from a top of the vertical leg ( 27 ), and

a support leg ( 32 ) extending horizontally from a bottom of the vertical leg ( 27 ) opposite the fastening les ( 24 ), the support leg ( 32 ) being configured to support the at least two mutually parallel tracks ( 71 , 72 ) arranged thereon; and

at least one insert part ( 41 ; 42 ), at least some regions of which can be encompassed by the carrier part ( 21 ; 22 ; 23 ),

wherein both the carrier part ( 21 ; 22 ; 23 ) and the insert part ( 41 ; 42 ) each have a constant cross-section along their entire lengths in a longitudinal direction ( 5 ), and

wherein a wall thickness of the vertical leg ( 27 ) is thinner in a region adjacent to the fastening leg ( 24 ) than in a region adjacent to the support leg ( 32 ).

2. The track fitting assembly ( 10 ) according to claim 1 ,

wherein the wall thickness of the vertical leg ( 27 ) increases steadily from the fastening leg ( 24 ) to the support leg ( 32 ).

3. The track fitting assembly ( 10 ) according to claim 1 ,

wherein a maximum wall thickness of the carrier part ( 21 ; 22 ; 23 ) is greater than one and a half times a minimum wall thickness of the carrier part ( 21 ; 22 ; 23 ).

4. The track fitting assembly ( 10 ) according to claim 1 ,

wherein a total length of the track fitting assembly ( 10 ) is

at least a sum of individual lengths of all carrier parts ( 21 ; 22 ; 23 ), and

at most 1.25 times the sum of the individual lengths of all carrier parts ( 21 ; 22 ; 23 ), and

at least a sum of individual lengths of all insert parts ( 41 ; 42 ), and

at most 1.25 times the sum of the individual lengths of all insert parts ( 41 ; 42 ).

5. The track fitting assembly ( 10 ) according to claim 1 ,

wherein the carrier part ( 21 ; 22 ; 23 ) comprises at least one T-rail ( 34 ) or at least one encompassing hook bar ( 39 ) for securing a position of the insert part ( 41 ; 42 ) relative to the carrier part ( 21 ; 22 ; 23 ) in regions.

6. The track fitting assembly ( 10 ) according to claim 1 ,

wherein the least two mutually parallel tracks ( 71 , 72 ) include one or more inner tracks ( 71 ) proximal to the vertical lee ( 27 ), and an outer track ( 72 ) distal from the vertical leg ( 27 ), and

wherein the one or more inner tracks ( 71 ) are formed on the carrier part ( 21 ; 22 ; 23 ), and

wherein the outer track ( 72 ) is not formed on the carrier part ( 21 ; 22 ; 23 ).

7. The track fitting assembly ( 10 ) according to claim 1 ,

wherein the insert part ( 41 ; 42 ) has at least one track ( 72 ).

8. The track fitting assembly ( 10 ) according to claim 7 ,

wherein an outer track ( 72 ) of the least two mutually parallel tracks ( 71 , 72 ) is arranged further from the vertical leg ( 27 ) than any other of the at least two mutually parallel tracks ( 71 , 72 ), and

wherein the outer track ( 72 ) is formed on the insert part ( 41 ; 42 ).

9. The track fitting assembly ( 10 ) according to claim 1 ,

wherein the insert part ( 41 ; 42 ) has at least one T-groove ( 55 ) or at least one rear grip bar ( 56 ) for engaging behind the carrier part ( 21 ; 22 ; 23 ) in regions.

10. The track fitting assembly ( 10 ) according to claim 1 ,

wherein the carrier part ( 21 ; 22 ; 23 ) and the insert part ( 41 , 42 ) engage in one another in a positive-locking manner and block at least five degrees of freedom.

11. A track system ( 11 ) comprising

at least one track fitting assembly ( 10 ) according to claim 1 and

at least one additional carrier part ( 21 ; 22 ; 23 ) and/or at least one additional insert part ( 41 ; 42 ),

wherein end faces ( 35 ) of two carrier parts ( 21 , 22 ; 22 , 23 ) contact one another at a common abutment point ( 36 ) and/or wherein front faces ( 44 ) of two insert parts ( 41 , 42 ) contact one another at a common contact point ( 45 ),

wherein each abutment point ( 36 ) is offset in the longitudinal direction ( 5 ) relative to a front face ( 44 ), and

wherein each contact point ( 45 ) is offset in the longitudinal direction ( 5 ) relative to an end face ( 35 ).

12. The track system ( 11 ) according to claim 11 ,

wherein a sum of lengths of all carrier parts ( 21 , 22 , 23 ) corresponds to a sum of lengths of all insert parts ( 41 , 42 ).

13. The track system ( 11 ) according to claim 11 ,

wherein at least one carrier part ( 21 ; 22 ; 23 ) and at least one insert part ( 41 ; 42 ) have different lengths.

14. A piece of furniture ( 1 ) with a track system ( 11 ) according to claim 11 .
