    • A hinge for automatically-closing a door which opens in both directions with a shock absorbing function, which allows installation on a door which opens in both directions and is opened inward and outward, including a cylinder 2; an operating rod 3 attached to one end of the cylinder 2 so as to be rotatable and restricted from moving in the longitudinal direction; two substantially V-shaped grooves 33 provided on an outer periphery of the operating rod 3 in the cylinder 2 so as to oppose to each other; two spheres 55 provided so as to engage the substantially V-shaped grooves 33 and disposed so as to oppose to each other; an upper piston 5 engaged with the spheres 55 and moved in the cylinder 2 in the longitudinal direction in conjunction with the movement of the spheres 55 with respect to the substantially V-shaped groove 33; a compression coil spring 4 disposed between the upper piston 5 and an upper end portion of the cylinder 2 and configured to urge the upper piston 5 to the other end side of the cylinder 2; and a fluid pressure shock absorbing mechanism configured to absorb a shock caused by the movement of the upper piston 5 to the other end side with a liquid pressure.

    • A counterbalancing system (30) for an inwardly/outwardly moving door (20) pivotable about an inclined hinge axis between fully closed and fully opened positions wherein the door (20) moves: i) upslope through angle beta and downslope through angle as it opens; and ii), upslope through angle and downslope through angle beta as it closes. The door (20) is hinged to a torque tube assembly (25) coincident with the hinge axis; a radial cam (38) having a profiled cam face (36) is mounted on the torque tube assembly (25) for rotation through the angles beta and ; and, springs (31, 32) are mounted within a housing (34) having a reciprocable piston (44) and a cam follower (35) carried thereby for biasing the follower (35) into engagement with the cam face (36). As door (20) moves downwardly through angles beta and , the springs (31, 32) are compressed and energy is stored therein. As door (20) is manually shifted upslope through angles beta and , the springs (31, 32) expand and the energy stored therein is released to impart a counterbalancing rotational torque to the torque tube assembly (25) to minimize the amount of manually applied torque required to move the door (20) along an upslope path.
