Abstract
In an upper door fitting of a sliding door which comprises a housing and two transverse guide rollers which each are rotatably supported each on a shaft stub, both shaft stubs extend parallel to each other and are arranged symmetrically with respect to a vertical longitudinal center plane. Both shaft stubs are rigidly mounted in the housing. In addition, the transverse guide rollers delimit an intake opening of the housing for guiding the sliding door so as to prevent impact noises and jerky movements of the sliding door.
Claims7
An upper door fitting (30) for a sliding door (10) movably guided between opposite spaced longitudinal webs (3, 4) of a door guide track (1) of the sliding door (10), the door fitting (30) comprising a housing (34) and two transverse guide rollers (31, 32) which are rotatably supported each on a shaft stub (81) at one end thereof in a cantilevered fashion so as to extend parallel to each other in spaced relationship and symmetrically with respect to a vertical longitudinal center plane of the door fitting (30), wherein
- both shaft stubs (81) are rigidly supported in the housing (34) of the upper door fitting (30) in spaced relationship with clearance between the longitudinal webs (3, 4) of the door guide track (1) and the transverse guide rollers (31, 32) so that, with the sliding door (10) fitted within the longitudinal webs (3, 4) of the door guide track (1), not both transverse guide rollers (31, 32) are in constant contact with the longitudinal webs (3, 4) of the door guide track (1), and
- the two transverse guide rollers (31, 32) which are spaced from each other extend outwardly beyond the housing (34) and inwardly beyond an accommodation passage (36) formed in the housing (34) for accommodating between the two transverse guide rollers (31, 32) a carrier (2) guiding the sliding door (10) to a rest or end position centrally within the longitudinal webs (3, 4).
