A flap assembly for a vehicle includes a flap, which by way of a linear actuator drive is pivotably drivable about a pivot axis from a closed position to an opened position. The drive includes a spring assembly that acts in a supporting manner on the flap. The actuator drive has an actuator housing that has one end articulated on the body of the vehicle, and an actuator rod being deployable from the other end of the housing. An external end of the actuator rod is articulated on the flap at a radial spacing from the pivot axis. The spring assembly is releasably disposed on the other end of the housing and has a compression spring supported by the actuator housing. The compression spring acts on the flap between a closed position and an initial opening angle of the flap.

A window vent assist mechanism for use with a vent window operable in a closed position and in a vented position can include a first support configured to connect to a header of a window frame and a second support configured to connect to an upper rail of a window vent disposed in the window frame. The window vent assist mechanism also includes a biasing member disposed between the header of the window frame and the upper rail of the window vent and nearer to an inner side of the vent window and a center of gravity of the window vent. The biasing member is configured to exert a force to urge the window vent to move relative to the window frame to reduce an operating force required to move the window vent to the vented position.

A furniture fitting includes a mounting device for releasably fastening the furniture fitting to one of two furniture parts, an actuating device which can be connected to the other of the two furniture parts and which is mounted so as to be movable relative to the mounting device, an energy accumulator which has a spring element formed from a wire, an the spring element is designed as a coil spring, and a force transmission mechanism by which energy which can be deposited in the energy accumulator can be transmitted to the actuating device. The wire has, in a cross-section normal to a longitudinal axis of the at least one wire, an outer contour which deviates from a circular shape.

This invention discloses a door opener, comprising a shell consisting of an upper cover plate (1) and a lower cover plate (2). The key is that a pushing device for pushing the door to rotate is provided in the shell. An end of a driving device, which has one or more springs, can drive, via a rotating member (3), the pushing device to rotate. A locking/releasing device, which cooperates with the driving device, is provided at the other end of the driving device. The structure of this invention is unique. It allows the door to be conveniently opened and will not cause any possible harm to the users.

An exemplary indicator mechanism is configured for use with a door closer including a body and an adjustment screw. The indicator mechanism generally includes an indicator, at least one indicium, and a cycloidal drive. The cycloidal drive is configured to selectively align the indicator and the at least one indicium in response to rotation of the adjustment screw to thereby indicate an operating characteristic of the door closer.

A furniture fitting including a carrier having a substantially flat fastening surface configured to be fixed to a furniture part, an actuating portion configured to be moved relative to the carrier, and an adjustment device for adjusting a position of the actuating portion relative to the carrier, with the adjustment device having at least one actuating element rotatable about a rotational axis. The actuating portion can be adjusted relative to the carrier by exerting a torque to the actuating element, and the rotational axis of the actuating element encloses an angle larger than 0° and smaller than 90° to the fastening surface of the carrier. The actuating element is coupled to the actuating portion via an angularly-movable coupling device, and the angularly-movable coupling device preferably comprises a ball joint.

A cover slides to protrude outward from a mounted position. At the same time, the cover may rotate to be opened, and thus a gap between the cover and an inlet portion on which the cover is mounted is minimized. The cover may be opened or closed easily and conveniently without degrading a sense of beauty and aesthetics at the portion on which the cover is mounted. The cover is caught and locked by a push latch. The cover may slide and rotate by being easily unlocked when being pressed by a hand. A user may easily and conveniently use the cover by a simple operation of pressing the cover. A sudden rotation of the cover is prevented using an elastic support member and a damper, and thus the cover can be conveniently used even while an occurrence of noise or collision between the cover and surroundings is prevented.
