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.

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.

Hinged window drive systems and window assemblies incorporating them provide for a combination of powered or motorized operation in addition to manual operation using a hand crank, with the opportunity for a user to switch between motorized operation and manual operation as needed.

A furniture hinge includes a body-side main element and a hinge cup, which is pivotally guided relative to the base element and which can be secured to a movable furniture part. The main element and the hinge cup are connected together via a lever mechanism. The furniture hinge is configured so that the lever mechanism has at least two levers, each of which is mounted on the hinge cup in a pivotal manner about a pivot axis that is aligned perpendicularly to the pivot axis of the hinge cup and each of which is provided with a toothing that meshes with another toothing arranged in the hinge cup.

A furniture board includes an integrated or inserted hinge for guiding a movable furniture part. The furniture board has two side faces, an end face, and an end-face recess for receiving a hinge. The hinge includes a basic element, a linear guide and a pivot guide hinged thereto. The linear guide has forcibly guided movable elements, to which the pivot guide is hinged at a distance from the basic element. Two side faces of the furniture board lie one in a first and one in a second plane. The linear guide and the hinged connection of the pivot guide to the linear guide lie between the first and the second plane, at least in a closed state of the hinge.

A multi-axis hinge mechanism for a vehicle door. The multi-axis hinge mechanism moves the vehicle door laterally and vertically by means of multiple axial rotations. An actuator pivots the door hinges attaching the door to the vehicle to move the door away from the vehicle while a set of gears translates the motion of the actuator into a vertical rotation of the door.

The invention relates to an actuator, comprising a spindle drive, a first gear which causes a translational displacement of a first connection unit connected to the spindle drive, and a second gear which engages with the first gear and which is rotationally coupled to a second connection unit, wherein the actuator is designed such that a relative rotation of the two gears with respect to each other causes an actuation of the spindle drive and a displacement of the spindle drive relative to the central axis of the second gear. Furthermore, the invention relates to devices for supporting a pivot member, such as a door, with respect to a parent assembly, such as a vehicle body.

A vertical door system includes: a door having a door frame, the door frame having at least one frame section; an operator; two vertical supports configured to: (a) be installable on opposite sides of the door opening and (b) support the vertical door, at least one of the vertical supports having: a guide track on a surface of the vertical support facing toward the door opening; and a drive system having: an elongated threaded rod drivable by the operator via a gearing arranged between the operator and the threaded rod; and one or more blocks, each block comprising a guide track connecting portion that connects to a guide track so the connected block is freely movable along the guide track, each block having a through-bore for accepting the threaded rod so that the block is positioned on the threaded rod and is movable along the threaded rod.

A locking device includes a cam that is formed in a rotating unit configured to rotate about a rotational center axis that is parallel to an opening width direction of a door, and the cam permits or prohibits movement of a door leaf in the opening width direction in accordance with a rotational position of the rotating unit.

The invention relates to a tensioning device (01) for tensioning a coil spring (02) that is supported on a main shaft (03) and at a fixed end is rotatably fixedly connected to a frame. The tensioning device (01) includes a gear drive (05), having a first gear element (06) that is axially displaceably guided on the main shaft (03) and rotatably fixedly connected to a free end of the coil spring (02), and having a second gear element (07) that is in drive engagement with the first gear element (06) in order to set the first gear element (06) in rotation about the main shaft (03). The tensioning device (01) also includes a retaining element (19) that holds the second gear element (11) in the position of drive engagement with the first gear element (06). Furthermore, the tensioning device (01) includes a drive element that is coupled to the second gear element (12) in order to set it in rotation. The gear drive is formed as a bevel gear transmission, wherein the first gear element (06) is formed as a bevel gear (06) and the second gear element (07) is formed as a bevel gear pinion (07), and wherein the rotational axes of the two gear elements (06, 07) extend perpendicularly to one another. The bevel gear (06) is integrally connected to a guide bushing (10), and has a central opening (09) through which the main shaft (03) extends, and has a cylindrical receiving section (12) in which the free end of the coil spring (02) is fastened.
