Mechanism for the movement of a wing of furniture with a downward folding opening, designed to be placed on one side of the furniture item, the mechanism being contained in a box consisting of two half-shells, and including a hinge including a plurality of levers, articulated one in relation to the other, to the box and to the wing for the movement of the latter, one of the levers being able to slide in a track formed in the box, another of the levers being able to rotate around a fulcrum point provided on the box and acting with one of its ends on the front side of a linear slider, the rear side of which acts on one end of a rocker lever, whose other end acts on.

A foot operable door opener operates, without using one's hands, and without an electrical assist. The entrance cycle is initiated by stepping on a pedal. This force drives the pedal a ¼ turn, engaging a soft wheel to open the door. The pedal is hard linked to a crank arm which goes into a unidirectional crank shaft hub to turn the wheel. The downward pressure from the pedal pivots a ratcheted hinge connected to a bracketed spring-loaded wheel assembly to keep constant pressure to the ground. A gear box or multiple pumps of the pedal turns the wheel two or more 360 degrees rotations, opening the door to allow the entrant to pass until the foot pedal is dis-engaged. This action releases the ratcheting hinge mechanism, allowing the spring assisted wheel assemble to rotate to its original up position, releasing the wheel from the ground, allowing the door to close.

A method and device for reducing excessive door or hatch closing velocity. An actuator containing a force alignment channel causes piston movement within a hydraulic cylinder creating resistance to prevent door or hatch slamming. Closing of the car door is against the resistance of the hydraulic cylinder as hydraulic fluid moves through at least one channel to allow hydraulic fluid to move from a first side of the piston to a second side of a piston. The resistance of the hydraulic cylinder to an incremental movement in the car door varies during the closing of the car door. A force alignment channel within an actuator creates variation of the resistance of the hydraulic cylinder to the incremental movement in the car door by varying a rate of movement of the piston within the hydraulic cylinder per degree of closure of the car door.

Hinge for the opening and the closing of hinged doors of furniture units, including a first fixed body designed to be housed in a seat of a horizontal plane of the structure of a furniture unit, such as a base or a top, and a second movable body designed to be housed in a seat of a door of the furniture unit, to actuate the door during opening and closing by way of of a movement mechanism including at least one lever or connecting rod connecting a pin placed on the fixed part of the hinge and a pin placed on the movable part, wherein the closing force of the door is determined by a spring, the spring acting, with a tilting action, on an extension of the connecting rod beyond the hinge pin.

Provided is a damping hinge for controlled closing of a door or gate. The damping hinge includes a first clamp plate configured to be mounted to a fixed supporting panel; a second clamp plate configured to be mounted to a panel of the door or gate, wherein the second clamp plate is connected with the first clamp plate for relative rotation about a hinge axis; and a damping mechanism arranged on at least one of the first clamp plate and the second clamp plate including a damper arranged substantially parallel to the hinge axis and configured to impact relative rotation of the second clamp plate towards the first clamp plate during closing of the hinge. The damping mechanism may be arranged such that the damping mechanism may be located outside of a plane of the respective panel and adjacent or next to an outer or facing surface of that panel.

A drive arrangement for a motor vehicle flap including a gas pressure element, the gas pressure element has an outwardly sealed cylinder and a piston moveable in the cylinder interior along the cylinder axis and subdivides the cylinder interior into two sub-chambers, the gas pressure element has a first drive connection connected to the cylinder, and a second drive connection connected to the piston, the cylinder filled with a fluid and the piston has an overflow channel arrangement to create a balancing flow between the two sub-chambers to balance a pressure drop between the two sub-chambers. The piston is assigned a switchable valve arrangement which, depending on the pressure drop between the two sub-chambers, to create different through-flow states differing the cross section of the overflow channel arrangement. Upon exceeding a predetermined threshold for the pressure drop, the valve arrangement switches to change the cross section of the overflow channel arrangement.

A hydraulically damped actuator closes a hinged closure system. The actuator includes an energy storing mechanism that stores energy when the closure system is being opened and restores the energy to effect closure of the closure system. A hydraulic damping mechanism damps the closing movement of the closure system. The actuator further includes a tubular cylinder barrel with first and a second ends and a rotatable shaft with first and a second extremities. The shaft extends through the tubular cylinder barrel. Both extremities of the shaft are available to be connected with a mechanical connector that transfers rotation of the closure system to the shaft, which allows the actuator to be mounted in two opposing orientations depending on the handedness of the closure system.
