Abstract
A carriage has a wing part which can be fastened to a wing and a roller part which is displaceable on a running rail. The wing part is displaceable in a positively controlled manner transversely to the running rail. The roller part has a height-adjustable roller upper part. The vertical adjustability of the roller upper part with respect to a roller holder of the roller part is achieved by means of an adjusting element which is displaceable by means of an adjusting screw. The adjusting element is preferably supported with at least one adjusting element bevel on a pendulum axle of the running roller holder and/or on an upper part bevel of the roller upper part.
Claims20
A carriage arrangement for displacing a heavy wing of a window or door in the displacement direction parallel to the main plane of a fixed frame of the window or door and for shifting the wing transversely to this main plane, wherein the carriage arrangement comprises the following:
- a) a driving bar arrangement arranged on the wing and which has a movable driving bar;
- b) a carriage having a wing part fastened to the wing and a roller part which is displaceable transversely to the main plane and has a plurality of rollers for displacement in the displacement direction;
- wherein the driving bar arrangement comprises a control projection which is arranged or formed on the driving bar and which is guided in a control slot of the roller part which is formed at least in sections obliquely to the main plane, wherein a movement of the driving bar causes a displacement of the roller part transversely to the main plane;
- wherein the roller part further comprises the following:
- c) a roller upper part with the control slot;
- d) a running roller holder having the plurality of rollers;
- e) an adjusting screw, configured to be actuated by a user, for height adjustment of the roller upper part relative to the running roller holder;
- wherein the roller part comprises an at least horizontally adjustable adjusting element with a first adjusting element bevel, wherein the actuation of the adjusting screw causes the at least horizontal movement of the adjusting element and the adjusting element indirectly or directly effects an at least vertical movement of the running roller holder via the first adjusting element bevel.
A carriage arrangement for displacing a heavy wing of a window or door in the displacement direction parallel to the main plane of a fixed frame of the window or door and for shifting the wing transversely to this main plane, wherein the carriage arrangement comprises the following:
- a) a driving bar arrangement arranged on the wing and which has a movable driving bar;
- b) a carriage having a wing part fastened to the wing and a roller part which is displaceable transversely to the main plane and has a plurality of rollers for displacement in the displacement direction;
- wherein the driving bar arrangement comprises a control projection which is arranged or formed on the driving bar and which is guided in a control slot of the roller part which is formed at least in sections obliquely to the main plane, wherein a movement of the driving bar causes a displacement of the roller part transversely to the main plane;
- wherein the roller part further comprises the following:
- c) a roller upper part with the control slot;
- d) a running roller holder having the plurality of rollers;
- e) an adjusting screw, configured to be actuated by a user, for height adjustment of the roller upper part relative to the running roller holder;
- wherein the roller part comprises an at least horizontally adjustable adjusting element with a first adjusting element bevel, wherein the actuation of the adjusting screw causes the at least horizontal movement of the adjusting element and the adjusting element indirectly or directly effects an at least vertical movement of the running roller holder via the first adjusting element bevel;
- wherein the roller upper part comprises a block, in the form of a metal block, in the upper side of which the control slot is formed and in the underside of which a vertically extending recess is formed, in which the adjusting element is at least partially accommodated.
