For clarification, the three are perpendicular to each other in the figures Spatial axes specified, namely the X axis, Y and Z axes, of which the X axis and Y axis define the drawing plane (XY plane) of FIGS. 1, 3, 5, 7, 8 and 10 and the X-axis and Z-axis are the drawing plane (XZ plane) of FIGS. 2, 4, 6, 9 and 11. When the fitting is installed, the XY level forms the level of the door leaf.

In Figures 1-7, 1 is the front carriage and 2 is the rear carriage and with 3 the middle carriage of a carriage arrangement of a fitting for called a lift and slide door. The fitting also includes others Functional elements, such as the faceplate 4 shown in Figure 7, which in essentially from a U-metal profile with the two legs 4 'and with the this leg connecting yoke section 4 "and in the longitudinal direction of the Face plate 4 a drive rod 5 longitudinally displaceable by a predetermined stroke H. is led. The movement of the drive rod 5 takes place via a, not shown, from a lift or swivel handle operated gear and is via a corner gear 6 transferred to the carriage arrangement.

The carriage 1 includes u. a. a bearing 7, which as a narrow, upright arranged block made of a suitable material, such as metal is manufactured and which is made using suitable fasteners, e.g. attached to the underside of a bearing bracket 8 using screws which, in turn, with its upper side lying on top in FIG. 1 on the lower, horizontal spar of a door leaf in the area of the fold there by suitable Fasteners, for example fastened by screws. The bearing bracket 8 is made in one piece with a boom 9 which extends in a longitudinal direction L of the Carriage 1 (X-axis) extends over one side of the bearing 7, namely at mounted hardware up to a corner area from the bottom of the door leaf and a vertical side of the door leaf adjoining this underside Folding area is formed.

A carriage element 10 is pivotally and displaceably provided on the bearing 7. This carriage element 10 consists essentially of two in the longitudinal direction L des Carriage 1 and the carriage element 10 mutually offset rollers 11, the with mounted fitting with a guide rail, not shown, on the lower, horizontal spar of a frame of the door in question. The two rollers 11 are received between two roller holder plates 12, which in Are spaced from each other and parallel to each other, with their Surface sides oriented parallel to the X axis and upright in the XY plane arranged. The two rollers 11 are on between these roller holder plates 12 one bearing pin 13 each using ball bearings around axes freely rotatable perpendicular to the surface sides of the roll holder plates 12 (Z axis) stored. The bearing bolts 13 are each at both ends in a bearing opening 13 ' Roll holder plate 12 held.

The roll holder plates lie with their mutually facing, inner sides 12 in the middle of the carriage element 10 against one each formed on the bearing 7 Leadership area. The bearing 7 is with a continuous slot-shaped opening provided, which forms an oblique lifting or guiding curve 14 which at embodiment shown is rectilinear. At 14 'is the stroke curve 14 denotes the surrounding edge area, which extends over the remaining side surface of the bearing 7 protrudes and against which the roller holder plates 12 with their facing each other Apply to the surface sides.

The guide curve 14 closes with the XZ plane of the top 8 ″ of the bearing bracket 8 an acute angle that opens towards the free end of the boom 9, and in such a way that the distance between the guide curve 14 and the top 8 " decreases with increasing distance from the free end of the boom 9.

The opening forming the guide curve 14 is from a guide pin 15 penetrated, which lies with its axis parallel to the Z axis and at both ends in each a bearing opening 15 'of the roll holder plate 12 is held.

About the guide pin 15, the carriage element 10 is pivotable by a certain amount and also radially to the axis of the guide pin 15 slidably on the bearing 7, in such a way that a stroke H _{X of} the carriage element 10 in the longitudinal axis (X axis) one Hub H _Y causes in the direction of the Y axis.

At least at the two ends of the carriage element 10 are the two Roll holder plates 12 connected to each other and at the required distance held apart, namely at the right end in Figures 1 and 2 via a block-like connecting element 16, which at the same time also for fastening a Endes a coupling rod 17, which the carriage 1 or its Carriage element 10 with another carriage, d. H. at the illustrated Embodiment with the middle carriage 3 or its carriage element 10 " combines. For the attachment of the connecting element 16 are the Roll holder plates 12 at this end for a riveted joint 18 with two circular, punched mounting holes 19 provided. The two openings 19 are in an axial direction perpendicular to the longitudinal extent of the roll holder plates 12 or offset in the Y axis.

The same openings 19 each roll holder plate 12 also on the Boom 9 adjacent end where the upper opening 19 for a riveted joint 18 'of the two roll holder plates 12 via an arranged between these plates Spacer sleeve 20 and the underlying opening 19 for storing a Hinge pin 21 is used, via which one end of a hinge lever 22 on the Carriage element 10 is articulated. Especially with regard to training and arrangement of the bearing openings 13 'for the bearing pin 13 and Fastening openings 19 are the roll holder plates 12 symmetrical to one Center plane M formed perpendicular to the surface sides as well is perpendicular to the longitudinal extent of the roll holder plate and thus parallel to YZ plane and in which the axis of the bearing opening 15 'is arranged. Both Roll holder plates 12 of the carriage element 10 are identical.

Via the lever 22, the carriage element 10 is connected in terms of drive to a bell lever 23, specifically via an articulated bolt 24. The bell lever 23 is part of the corner gear 6 and is in turn articulated by means of an articulated bolt 25 on the free end of the boom 9. On the bell lever 23, a connecting piece 27 engages via a hinge pin 26, which is guided in a guide piece 28 which is firmly connected to the free end of the boom 9 in the direction of its longitudinal axis and in the direction of the Y-axis and, with the fitting fitted, with the drive rod 5 is connected so that when moving the drive rod 5 by the drive rod stroke H via the corner gear 6 the movement of the carriage element 10 takes place in accordance with the stroke H _X.

FIGS. 3 and 4 show the carriage 2, the carriage element 10 'of which is different the carriage element 10 essentially differs only in that the Connector 16 is located at the left end. The bearing 7 is on a support or Fastening plate 8 'is provided, which does not have the boom 9.

Figures 5 and 6 show the carriage 3, which on a door leaf between the Carriage 1 and 2 is provided, in particular when the door leaf in the X-axis has a large dimension (width) and / or high weight. The Carriage element 10 "differs from carriage element 10 in essentially in that the roll holder plates 12 at both ends over each a connecting element 16 are connected to each other, which then over the Coupling rods 17 the connection to the other two carriages 1 and 2 produce.

The formation of the roll holder plates 12 is symmetrical to the center plane M. not only the advantage that these sheets for either the left and right side of one Carriages can be used, but the same training of the Roll holder plates can be used for all carriages. The use of the Bearing bracket 8 or 8 'has the advantage that one and the same bearing 7 for everyone Carriage 1 - 3 can be used.

To make installation on a door leaf easier, the carriages 1 - 3 prove a zero fixation during their manufacture, which during assembly is effective and with the door fully installed the first time the fitting is operated will be annulled.

In the carriage 1 this zero fixation is formed in that the Corner gear 6 via a shearable fixing bolt 29 which, for example, consists of Plastic is made, is fixed in the zero position, which is the lowered state corresponds to a door provided with the fitting or with the carriage. The Fixing bolt 29 is at both ends in a bore in the free end of the boom 9 held and passes through a hole in the bell lever 23. When loosening the Zero fixation, the fixing bolt 29 or its components fall down on an area of the floor frame, which usually forms the threshold, so that the remnants of the fixing bolt 29 are removed there during normal cleaning, under no circumstances enter the carriage 1 or the carriage element 10 where such remnants of the fixing bolt 29 could cause interference.

With carriages 2 and 3, the zero point fixation is achieved in that the bearing 7 has at least one integrally formed fixing lug 30, which is used for fixing the zero point abuts against an edge of one of the roll holder plates 12 and when the Zero fixing is canceled by the first actuation of the fitting.

With 31 stops are also referred to, against which the roller holder plates 12 in lowered state or in the zero position, so that this at least undesired pivoting of the carriage elements 10, 10a or during assembly 10b around the respective guide pin 15 is avoided.

FIGS. 8-11 show a front embodiment as a further possible embodiment Carriage 1a and a rear carriage 2a, which differ from the carriage 1 and 2 essentially only by the shape of the roll holder plates 12 corresponding roller holder plates 12a, the bearing 7 corresponding to the bearing 7a or 7a 'and the corresponding to the connecting elements 16 Differentiate connecting elements 16a.

The roll holder plates 12a are narrower than the roll holder plates 12 or slimmer and only one at each end Connection or attachment opening 19 provided. Furthermore, the Roll holder plates 12a convex on their upper side in FIGS. 8 and 10 and essentially concave on its lower side. The camp 7 has turn gear 6 on a cantilever, where the guide or Stroke curve 14 the greatest distance from the top of the respective bearing 7 or 7a has, this bearing is essentially limited to a stroke curve 14 Edge area 14 'reduced.

The carriages 1a and 2a are distinguished by one compared to carriages 1 and 2 somewhat reduced overall height. The roll holder plates are in the lowered state 12a in turn against stops 31a.

The invention has been described above using an exemplary embodiment. It it goes without saying that changes and modifications are possible without this the inventive idea underlying the invention is abandoned.
