Abstract
The drive according to the invention for a wing of a door, a window or the like comprises a housing, a drive shaft supported rotatably in the housing, and a piston that interacts with the drive shaft and is guided slidably in the housing. In addition, the drive comprises energy conversion means interacting with the piston, by which energy from the movement of the piston can be converted to electrical energy, and electrical energy produced in this way can be converted back to mechanical energy, to supply at least one electrical component with electric current, to generate a braking torque and/or to drive the piston, especially to support the closing and/or opening movement.
Claims16
A drive (10) for a wing of a door, a window or the like, with a housing (12), a drive shaft (14) supported rotatably in the housing (12), and a piston (16) cooperating with the drive shaft (14) and guided slidably in the housing (12), wherein the drive (10) has means (18) for energy conversion cooperating with the piston (16), assigned to it, through which mechanical movement energy of the piston (16) can be converted into electrical energy and electrical energy generated in this way can be converted into mechanical energy, in order especially to supply at least one electrical component (50, 54, 66-74) with electric current, to generate a braking torque and/or to drive the piston (16), especially to support the closing and/or opening movement.
The drive according to claim, 1 characterized in that the push rod (24) in each case is acted upon by spring force in the direction of the piston (16) and thus kept in engagement with this.
