Abstract
In order to improve operability and user comfort for vertically sliding or displaceable facade components, a weight compensation device for vertically displaceable facade components includes a spring element for at least partial compensation of its own weight of a vertically displaceable facade component and a compensator. The spring element provides a spring force as a driving force (FAN) for lifting the vertically displaceable facade component. The spring element is movable between a compressed state (PK) and an expanded state (PE). The spring force has a decreasing value when moving from the compressed state to the expanded state. The compensator at least partially compensates for the decrease in the input force and provides an output force (FAB) that decreases less than the input force.

A weight compensation device for vertically displaceable facade components, comprising:
- a spring element for an at least partial compensation of a weight of a vertically displaceable facade component;
- a compensator;
- wherein the spring element provides a spring force as a driving force (FAN) for lifting the vertically displaceable facade component, and wherein the spring element is movable between a compressed state (PK) and an expanded state (PE);
- wherein the spring force has a decreasing value when moving from the compressed state to the expanded state;
- and
- wherein the compensator at least partially compensates for the decrease in the spring force and provides an output force (FAB) that decreases less than the spring force,
- wherein the compensator has a force input and a force output;
- wherein a gear mechanism is provided between the force input and the force output,
- wherein a transmission comprises a cable reel on which a cable is windable that is connectable to the vertically displaceable facade component;
- wherein the cable reel is rotatably driven by the spring element;
- wherein the cable reel has a decreasing winding circumference for the windable cable, and
- wherein the spring element displaces the cable reel during the winding process in pulling direction of the cable winding on the reel, so that the vertically displaceable facade component is movable by a stroke composed of two movements, wherein in one movement the cable is windable on the cable reel and wherein in another movement the cable reel is displaceable, and wherein both movements are simultaneously executable.
