PROBLEM TO BE SOLVED: To provide an opening/closing body drive controller for a vehicle capable of suppressing erroneous detection of pinching of a foreign matter in a fully closed state or in the vicinity thereof at the time of closing drive of an opening/closing body.SOLUTION: On the basis of a magnitude relation between a rotational speed difference DN that is a deviation between a rotational speed of a motor detected in an idle running section and a present rotational speed of the motor subsequently detected, and a detection threshold value Th set beforehand, an opening/closing body drive controller for a vehicle detects pinching of a foreign matter. The detection threshold value Th is set so as to maintain a predetermined threshold value at the time of full-close Thc from a stroke St2 included in an error range, stroke region ΔSt2, of a stroke St of the motor corresponding to a fully closed state of an opening/closing body to a maximum stroke St3 of the error range while monotonically decreasing as the stroke St of the motor associated with closing drive of the opening/closing body increases so as to be equal to the predetermined threshold value at the time of full-close Thc corresponding to the fully closed state of the opening/closing body at the stroke St2.
Abstract:
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.

Abstract:
The present invention provides for apparatus and methods for operating a garage door. An embodiment of an operating assembly for a door includes a shaft, a graduated drum, and an energy storing member. The shaft is coupled to the door such that the shaft rotates in a first direction as the door is opened and rotates in a second direction as the door is closed. The coupling of the shaft to the door is typically accomplished by a cable. The graduated drum is coupled to the shaft and the energy storing member is coupled to the graduated drum by another cable. The energy storing member is arranged such that the energy storing member stores energy as the door is closed and releases stored energy as the door is opened to assist in the raising and lowering of the door.
