The present invention discloses an overhead door hinge mechanism, comprising a hinge box boy, wherein the side wall of the hinge box body is provided with a telescopic arm assembly used for connecting with the door backplane of an overhead door, the telescopic arm assembly is provided with a two-stage rotating arm mechanism used for driving the door backplane to upwards flip over the range of a right angle, a connecting and rotating block and a spring stress block are rotationally fixed in the hinge box body, the telescopic arm assembly is rotationally fixed on the side wall of the hinge box body through the connecting and rotating block. The present invention can enable the overhead door to flip over a right angle and reduce the mechanical loss of the spring through the clamping mechanism, and has stable supporting structure and long service life.

A multi-link hinge is proposed. The multi-link hinge is configured to facilitate closing and opening of a door, is capable of sufficiently securing a maximum opening angle of the door while decreasing a gap between the door and a main body, and is also capable of providing convenience to a user when the user opens and closes the door.

A cover system for covering a vehicle tow hitch connector includes at least a first retention member including a first retention slot, and a first door support coupled to the first retention member. A second door support is positioned opposite the first door support. A door is rotatably coupled to the first and second door supports. The door includes a first retention projection structured to be received in the first retention slot to position the door in a closed orientation.

A furniture drive for moving a furniture front relative a furniture carcass includes a base body to be fixed to the furniture carcass, and an actuating arm pivotally supported on the base body about at least one first pivoting axis in a mounted condition. The actuating arm includes a plurality of levers hingedly connected to one another, and at least two of the levers of the actuating arm are configured to be releasably connected to the base body of the furniture drive. At least the levers of the actuating arm are symmetrically arranged with respect to a notional middle plane of the actuating arm.

A furniture drive includes a carrier and an actuating arm assembly arranged on the carrier and including a movably-supported actuating arm. The furniture drive also includes a spring device for applying a force to the actuating arm assembly, the spring device being connected to the actuating arm assembly via an engagement location, a transmission mechanism for transmitting a force of the spring device to the actuating arm assembly, and an adjustment device including a rotatably-supported adjustment element. A relative position of the engagement location can be adjusted by a rotation of the adjustment element. The furniture drive further includes an overload safety device configured to couple the adjustment element with the transmission mechanism upon rotation of the adjustment element with torque below a predetermined torque, and to decouple the adjustment element from the transmission mechanism upon rotation of the adjustment element with torque above the predetermined torque.

A furniture fitting for the movable mounting of a furniture part, in particular a furniture flap, on a furniture panel, includes a main body, a rotary lever, and a bearing pin. The bearing pin is connected to the main body and/or to at least one base lever, and the rotary lever has a hole and the bearing pin projects through the hole. The rotary lever has, in at least one region surrounding the hole, a widened portion which extends at least in a direction parallel to a longitudinal axis of the bearing pin.

A furniture fitting includes a main body and a covering cap. The main body can be at least partially inserted in a furniture panel of a furniture carcass, and the covering cap can be installed on the main body to at least partially cover at least one lateral face of the main body in the installed state. The installation position of the covering cap can be adjusted relative to the main body, preferably without tools.

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.
