Abstract: A driving mechanism for sliding a windowed frame guided by an outer frame. The sliding frame is attached to two vertical racks which engage with two pinions. The pinions are connected with a joint axle driven by a couple of engaged bevel gearwheels connected to a crank or to an electric motor. The joint axle with the pinions can be housed in a recess carved at the lower plank of a static window's frame. A compact motorized option in which each pinion is coupled with a gearbox and both gearboxes are driven by a central electric motor also can be housed entirely in the static window's recess. The motorized options also include: a control unit for controlling the direction and speed of the sliding, two limit switches for stopping the frame at highest and lowest positions, an electrical overload sensor which detects sudden sliding obstructions and a burglar alarm.

Abstract: A mechanism for vertically sliding a windowed frame in one track alongside a static frame installed in a second track. The mechanism consists of two vertical racks installed on the sliding frame, which engage with two pinions coupled with a joint axle which are installed within the lower horizontal plank of the static frame. Turning the joint axle turns also the pinions which move the frame vertically. There are two options for turning the joint axle. The manual option involves turning a crank, the electrical option involves an electric motor coupled with a gearbox. The electrical option also includes a control unit for controlling the direction and speed of the sliding, two limit switches for stopping the frame at highest and lowest positions, an electrical overload sensor which detects sudden sliding obstructions and a burglar alarm. The sliding frame also includes four rollers which reduce the sliding friction.
