Provided is a stay which is capable of stabilizing movement of a component part used for transmitting, or not transmitting, the torque of one of a first member and a second member to the other. When a second member rotates relative to a first member in one direction, a cam base moves away from a disk in the direction of the rotation axis, and the second member and the cam base rotate relative to the first member and the disk. When the second member rotates relative to the first member in the opposite direction, the cam base moves towards the disk in the direction of the rotation axis, and the second member, the cam base and disk rotate relative to the first member with resistance force.

An adjustable-angle positioning and self-closing hinge has two hinge leaves, a fixing pin, a screw knuckle, a screw ring, a fixing base, and an adjusting base; each leaf of the hinge comprises a knuckle and a leaf fastened outside the knuckle; the fixing pin has a threaded pin; the screw knuckle is fastened inside the knuckle of one of the hinge leaves, the fixing base is fastened inside the knuckle of one of the hinge leaves, and the screw knuckle and the fixing base are spaced separately; between the screw knuckle and fixing base in the knuckles of the two hinge leaves are disposed the fixing pin, the screw ring, two magnets, springs, and the adjusting base; the threaded pin of the fixing pin is screwed to the screw knuckle; a first spring abuts between the fixing pin and the front ring edge and gasket of a cup body.

A refrigerator includes a cabinet that defines a first storage compartment; a first door that is opened or closed to allow or prevent access to an interior of the first storage compartment; a storing device coupled to the first door to define a second storage compartment, wherein, when the first door is closed, the second storage compartment is disposed in the first storage compartment; and a second door connected to the first door and configured to be opened or closed to allow or prevent access to an interior of the second storage compartment, wherein the interior of the second storage compartment is accessible when the first door is closed and the second door is opened, wherein the first door includes a plurality of first coupling parts to which the storing device is coupled, wherein the storing device includes: a frame; and a basket installed on the frame, wherein each of the frame and the basket includes at least one second coupling part interacting with at least one of the plurality of first coupling parts, wherein a front surface of the second door is positioned to be generally coplanar with at least a portion of a front surface of the first door.

A hinge arrangement includes a first hinge plate assembly including a pivot housing movable about a pivot axis and including a threaded adjustment pin transverse to the pivot axis away from the housing. A second hinge plate assembly includes an adjustment housing, the adjustment housing including a threaded portion. The threaded adjustment pin is threaded into the adjustment housing to connect the first hinge plate assembly to the second hinge plate assembly. Relative rotation between the threaded adjustment pin and the threaded portion of the adjustment housing causes the second hinge plate assembly to move along a length of the threaded adjustment pin, altering a spacing between a mount plate portion of the first hinge plate assembly and a mount plate portion of the second hinge plate assembly. A connection between the pivot housing and the first hinge plate assembly may include a torsional and/or gravity closing bias.

A hinge mechanism includes a shaft, a first connecting member pivoted to the shaft and connected to a first body, a second connecting member fixed to the shaft and connected to a second body, a limiting frame, a rail base, a pin movably disposed through a slot of the limiting frame, and an elastic member connected to the pin and abutting against the first connecting member for driving the pin against the rail base. The limiting frame is fixed to the first connecting body and pivoted to the shaft. The rail base is fixed to the shaft and has first, second, third arc-shaped rails and a transition rail. When the first body rotates an expanding angle relative to the second body in a first rotating direction, the pin moves along the first arc-shaped rail to the transition rail and abuts against a first stopping end surface of the transition rail.

Provided is a torque hinge which can be easily assembled. A torque hinge includes a restricting member 3 having a hole 31, a shaft 4 passed through the hole 31 of the restricting member 3, a friction member 6 engaged with the shaft 4 in an interference fitting state so as to generate torque due to friction to the shaft 4 which relatively rotates and fitted in the hole 31 of the restricting member 6, and a fixing shaft 41 for unrotatably fixing the friction member 6 to the restricting member 3, the fixing shaft 41 intervening between the friction member 6 and the restricting member 3. The fixing shaft 41 presses a wedge-shaped rotation locking portion 44 of the friction member 6 onto an inner surface of the hole 31 of the restricting member 3.

A hinge mechanism includes a shaft, a first connecting member pivoted to the shaft and connected to a first body, a second connecting member fixed to the shaft and connected to a second body, a limiting frame, a rail base, a pin movably disposed through a slot of the limiting frame, and an elastic member connected to the pin and abutting against the first connecting member for driving the pin against the rail base. The limiting frame is fixed to the first connecting body and pivoted to the shaft. The rail base is fixed to the shaft and has first, second, third arc-shaped rails and a transition rail. When the first body rotates an expanding angle relative to the second body in a first rotating direction, the pin moves along the first arc-shaped rail to the transition rail and abuts against a first stopping end surface of the transition rail.

A swivel joint system for pivotally connecting a mirror to a vehicle includes a first arm, a second arm, a locking pin, a spring element and a centering element. The first arm has first and second bearing shells. The second arm has a first counter bearing shell and a second counter bearing shell. The counter bearing shells are disposed between the first bearing shell and the second bearing shell. A first latching surface of the first counter bearing shell contacts and presses against a second latching surface of the first bearing shell. The locking pin passes through the first bearing shell, the second bearing shell and a hole in the centering element. The second arm swivels relative to the first arm about a joint axis that is oriented co-axially to the locking pin. The spring element pushes the locking pin away from the first counter bearing shell.
