A furniture fitting includes a lever mechanism for moving a furniture part, the lever mechanism including a lever pivotally supported about a hinge axis, and the lever has a, in particular cylindrical, opening in which the hinge axis is arranged with a clearance. A force storage member, preferably including a spring device, is provided for applying a force to the lever mechanism. The hinge axis, upon a pivoting movement of the lever, is movable from a first bearing location within the opening to a second bearing location within the opening under the influence of the force storage member. A spring element pressurizes the hinge axis with a force at least in a direction extending transversely to a notional connecting line of the two bearing locations of the hinge axis within the opening of the lever.

A refrigerator includes a cabinet including an outer case forming an external appearance and a storage compartment, a refrigerator door coupled to the cabinet to open or close the storage compartment, an installation bracket coupled to the outer case inside the outer case, a door opening device installed in the installation bracket outside the outer case and including a push member for opening or closing the refrigerator door, and a buffer member disposed a coupling portion between the door opening device and the installation bracket.

The present disclosure relates to a pulley device, a sliding door, and a sliding window. The pulley device includes: a pulley component including a pulley; a connecting component including a rocker, one end of the rocker being rotatably connected to the pulley component; and a housing including a bottom plate and two side plates. The two side plates are fixed to two opposed sides of the bottom plate, respectively, so that the bottom plate and the side plates jointly define a receiving cavity configured to receive the pulley component and the connecting component. A surface of the side plate facing the receiving cavity defines a receiving groove along a length direction of the side plate, and the other end of the rocker is received in the receiving groove and is capable of sliding along the receiving groove.

A structure for assisting with opening and closing of a lower door includes a lower door having an upper end configured to be rotated open with respect to a bottom surface of a vehicle body, and a rotary unit configured to be fixed to the bottom surface of the vehicle body and configured to rotate in opposite directions to assist with opening and closing of the lower door.

A refrigerator includes: a cabinet; a door rotatably connected to the cabinet by a hinge; and a door opening device for opening the door. The door opening device includes a driving motor and a push member configured to move in the forward/backward direction. The push member includes a first end portion positioned close to the front surface of the cabinet and a second end portion positioned on the opposite side of the first end portion. The cabinet includes a cabinet side wall positioned close to the hinge. The door includes a door side wall positioned close to the hinge. When the door is closed, the horizontal distance between the first end portion and the cabinet side wall or the door side wall is smaller than the horizontal distance between the second end portion and the cabinet side wall or the door side wall.

The present invention relates to a device capable of guiding a stable rotational actuation between a first support bracket fixedly connected to a supporting frame side of a door frame and a second support bracket fixedly connected to the door side in a gear hinge unit constituting a rotating door, specifically, in a door hinge in which a gear hinge unit is provided between the first support bracket fixedly connected to the support frame side of the door frame and the second support bracket fixedly connected to the door side, by minimizing the compressive stress generated in the lower gear hinge unit under a neutral axis of the door and the tensile stress generated in the upper gear hinge unit above the neutral axis of the door by the rotational moment applied to the gear hinge unit due to the load of the door, it is possible not only to secure and maintain the correct opening/closing performance of the door, but also to minimize damage to parts caused by friction or friction noise in the door hinge.

Provided is a sliding door drive device enabling suppression of bulging against a body panel being a fixing target. The sliding door drive device includes a long guide frame, a first driven pulley and a second driven pulley being supported at both ends of the guide frame in a longitudinal direction, respectively, a belt being wrapped around the first driven pulley and the second driven pulley, and a belt drive part driving the belt. The guide frame includes a guide wall guiding the belt between the first driven pulley and the second driven pulley. The sliding door drive device further includes a sliding plate being placed at a position sandwiching the belt with an inner side of a curved part of the guide wall, and sliding on the driven belt.

A door mechanism for a compartment on an aircraft that includes a door with a first lower guide, a second lower guide, a first upper guide, and a second upper guide. The door mechanism includes a first lower track, a second lower track, a first upper track, and a second upper track, each having a guide track. The first lower guide, second guide, first upper guide, and second upper guide being configured to travel along the corresponding guide track to enable the door to move between open and closed positions. The door in the open position may be positioned within a portion the compartment or may be positioned above the compartment. The first and second lower tracks may include a first a second gap that enables the door to be selectively uncoupled from the first and second lower track guides permitting the door to swing away from the compartment.

A cylinder-piston unit with load-dependent damping includes a piston longitudinally displaceable in a cylinder. The piston has a first piston channel and a second piston channel, which each connect a compensation space on one side of the piston to a displacement space side on an opposite side of the piston. On the displacement space side a throttle channel connects one first piston channel to the piston lateral surface. On its displacement space side the piston has a piston journal, which carries a resiliently deformable piston disc. The piston disc is displaceable and covers the throttle channel at least partially. The displacement space side has at least one relief portion deviating from a piston end face plane. The relief portion is delimited on a number of sides by a plurality of boundary lines running concentrically with respect to the central axis. Each of these boundary lines can be differentiated continuously.

The present disclosure relates to a nut leadscrew type automatic door opening and closing mechanism, an automobile automatic door and an automobile. The nut leadscrew type automatic door opening and closing mechanism includes a driving device, a leadscrew, a nut pushing block and a pushing rod, wherein the driving device is fixedly connected to a door, the leadscrew is rotatably mounted on the door, the nut pushing block is sleeved on the leadscrew, a first end of the pushing rod is hinged to the nut pushing block, a second end of the pushing rod is hinged to a main body, the driving device is capable of driving the leadscrew to rotate, so as to allow the nut pushing block and the pushing rod to be reciprocally linearly movable along the leadscrew, and then allow the pushing rod to drive the door to open or close relative to the main body.
