Abstract
A pressing device has a roller part, a control part and a fastening part. The pressing device can be mounted to a leaf of a window or door. The roller part is movable in the mounted state of the pressing device, in particular, vertically relative to the control part. The control part is movable horizontally to the fastening part in a positively controlled manner. A spring element is provided between the control part and the roller part in order to subject the roller part, in addition to the force of gravity, to a downwardly directed spring force, i.e., towards the running rail.
Claims15
A pressing device for a window or a door having a fixed frame, a running rail extending horizontally in a longitudinal direction, and a displaceable leaf, wherein the pressing device comprises:
- a) a fastening part configured to be fastened to the leaf and has a guide slot extending horizontally in the longitudinal direction along the fastening part;
- b) a control part having a control slot extending horizontally, wherein at least one portion of the control slot is slanted extending obliquely to the longitudinal direction;
- c) a roller part having a running roller configured for rolling on the running rail in the longitudinal direction;
- d) a driving bar having a control pin arranged or formed on the driving bar, the control pin extending through the guide slot and into the control slot;
- wherein the fastening part is configured to move horizontally and perpendicular to the longitudinal direction in a positively-controlled manner relative to the control part;
- and
- wherein the roller part is configured to move vertically relative to the control part, and including a spring element biased between the roller part and the control part configured to compensate for a distance variation between the leaf and the running rail when the leaf is moved in the longitudinal direction;
- wherein the window or the door has two carriages that are fastened to the underside of the leaf, wherein the pressing device is arranged between the two carriages, and wherein the two carriages do not include a spring element configured to compensate for a distance variation between the leaf and the running rail when the leaf is moved in the longitudinal direction.
A window or a door, comprising:
- a fixed frame;
- a running rail extending horizontally in a longitudinal direction;
- a displaceable leaf;
- a pressing device, wherein the pressing device comprises:
- a) a fastening part configured to be fastened to the leaf and has a guide slot extending horizontally in the longitudinal direction along the fastening part;
- b) a control part having a control slot extending horizontally, wherein at least one portion of the control slot is slanted extending obliquely to the longitudinal direction;
- c) a roller part having a running roller configured for rolling on the running rail in the longitudinal direction;
- d) a driving bar having a control pin arranged or formed on the driving bar, the control pin extending through the guide slot and into the control slot;
- wherein the fastening part is configured to move horizontally and perpendicular to the longitudinal direction in a positively-controlled manner relative to the control part;
- and
- wherein the roller part is configured to move vertically relative to the control part, and including a spring element biased between the roller part and the control part configured to compensate for a distance variation between the leaf and the running rail when the leaf is moved in the longitudinal direction;
- wherein the pressing device is fastened to an underside of the leaf;
- wherein the window or the door has two carriages that are fastened to the underside of the leaf;
- and
- wherein the pressing device is arranged between the two carriages.
