A drive device for moving a leaf, in particular a door leaf or a window leaf, with an electric machine including an, in particular single, stator and an, in particular single, rotor, which can be rotated about a machine axis, and with a gear coupled to the electric machine. The gear has a first gear element, which can be rotated coaxially with the machine axis, with the first gear element being connected to the rotor in a rotationally-fixed manner.

A furniture fitting includes a first fitting portion to be fixed to a furniture panel, and a second fitting portion to be fixed to a movably-mounted furniture part, the second fitting portion being pivotally connected to the first fitting portion. The first fitting portion includes a mounting portion having a fastening device for mounting the mounting portion to the furniture panel, and the first fitting portion includes a coupling portion hingedly connected to the second fitting portion. The coupling portion is releasably connected to the mounting portion, and the mounting portion includes a housing. The coupling portion, when connected with the mounting portion, is received within the housing. The coupling portion is releasably connected to the mounting portion by a locking device, the locking device including a movably-mounted locking element for releasably locking the coupling portion, and the locking element is pressurized by a force storage member.

A device includes a housing. The housing can define a duct having a central axis. A first loading surface can extend into the duct toward the central axis, while a second loading surface can extend into the duct toward the central axis. A first driver and a second driver can be situated within the duct along the central axis. The first driver can abut the second driver. A first spring biases the first driver away from the first loading surface, thereby causing the first driver to apply a first loading force to the second driver. A second spring applies a second loading force to the second driver, along a common direction with the first loading force, to bias the second driver away from the second loading surface, with the first spring and second spring operating in parallel on the second driver.

A multi-link door hinge capable of facilitating the closing of a door and implementing the shock-absorbing performance of the door during the closing thereof. To this end, the multi-link door hinge includes: a main frame mounted to a main body of an object having a door; a door frame mounted to the door; a body frame rotatably connected to a first side of the main frame; an inner link and an outer link connecting the door frame to the body frame; a plate spring link allowing the outer link to be rotatably connected to the main frame; a locking piece rotatably mounted between side walls of the inner link; an elastic member; and a hook, a first side of which is fixed in the body frame and a second side of which is configured to be held in a second side of the locking piece.

Provided is a hinge that can prevent a defect, a failure, or the like with greater certainty, and enables inspection and repair work to be efficiently carried out. A hinge comprises a first wing member that is connected to a first connection object and a second wing member that is connected to a second connection object. The hinge rotatably connects the second connection object to the first connection object. The hinge comprises a sensor that detects a change inside the hinge or in a prescribed external environment change in the external environment detected by the sensor to the outside via a sensor that detects a prescribed component constituting an odor, a gas sensor that detects a prescribed gas, a dust sensor that detects the amount of dust, and a illumination sensor that detects brightness.

A hinge mechanism comprising first and second members rotatable relative to one another about a hinge axis from a first to a second position; and a biasing arrangement operative to adopt an active mode to bias the first and second members into at least one relative position and operative to adopt an inactive mode where the biasing arrangement does not provide bias to the first or second members to undergo relative rotation, wherein the biasing arrangement remains in the inactive mode on relative rotation of the first and second members through a first selected angular displacement between the first position and the second position, and is in the active mode on relative rotation of the first and second members through a second selected angular displacement between the first position and the second position.

A door drive assembly including: a drive arm including a first end configured to be rotatably coupled to the body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a drive mechanism coupled to the drive arm and configured to rotate the drive arm between an open position and a closed position. The door drive assembly also includes a control arm including a first end configured to be rotatably coupled to a vehicle body and a second end configured to be rotatably coupled to the door. The door drive assembly also includes a race configured to be disposed between the body and the first end of the control arm where the first end of control arm is configured to translate by a first distance along the race as the drive arm rotates between the open and closed positions.

A drive unit for closing a leaf of a door or a window comprises an energy accumulator for providing a closing force for closing the leaf, a damping device which counteracts the closing force and has an electric motor which can be operated as a generator and can be coupled to an actuating element of the drive unit, and a control device for controlling the electric motor. The control device is designed to determine a nominal path curve which indicates a position of the leaf or a closing speed of the leaf in dependence upon time, and to perform the control of the electric motor in order to damp the closing movement of the leaf on the basis of the established target path curve.

A hinge, wherein, inter alia, intrusion of foreign matter in a contacting portion of a slide member and a cam member and resulting adhesion of an oil provided in the cam member to the foreign matter is reliability prevented from the closed state to the open state of a second wing member. The hinge is provided with an oil fence disposed on the outside close to the contacting portion of the cam member and slide member, the oil fence preventing, from the closed slate to the open state of the second wing member, foreign matter front intruding into the contacting portion of the slide member and cant member from the outside of the slide member and cant member.

An appliance includes a linear hinge assembly that couples a door to a cabinet. The linear hinge assembly includes a bearing assembly mounted to the cabinet and an elongated shaft received within the bearing assembly for sliding along a translation axis. A cam is mounted to the door and is rotatably coupled to a distal end portion of the elongated shaft such that such that the door is rotatable about a pivot axis that extends through the distal end portion of the elongated shaft. A timing cable extends from a fixed location on the cabinet to a fixed location on a cam profile such that the timing cable wraps around the cam when the door is moved toward a closed position and unwraps when the door is moved toward an open position.
