Abstract:
There is provided a driving control device of an opening and closing body, which drives the opening and closing body in a closed state by a motor through an idling section thereof. The device includes a calculation section for calculating a rotation speed difference between a rotation speed of the motor in the idling section and a current rotation speed of the motor; and an insertion detection section for detecting insertion of a foreign member based on the calculated rotation speed difference and a predetermined threshold value. The threshold value monotonously decreases according to an increase in the rotation amount of the motor to coincide with a fully-closed state threshold value at a predetermined rotation amount of the motor within an error range of the rotation amount corresponding to the fully-closed state, and to maintain the fully-closed state threshold value to a maximum rotation amount in the error range.
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.
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 device for actuating a pivoting movement of a vehicle flap about a pivot axis includes a gas spring having a cylinder and a piston rod protruding from the cylinder. Either the cylinder or the piston rod is coupled to a fixed component of the vehicle body, and the other one of cylinder and piston rod is coupled to the flap at a distance from the pivot axis. A flexurally rigid guide extends parallel adjacent to the gas spring and is fixedly connected to the cylinder of the gas spring. One region of a flexible tension and compression element is guided in the guide and operatively connected to the flap, and a second region is guided in a flexible casing and operatively connected to a reversible drive, so that the flexible tension and compression element can be motor driven.
Abstract:
A storage compartment for a vehicle has a storage compartment cover which is pivotably mounted toward two sides. The latter can be pivoted either toward one side or toward the other side. In order to design the storage compartment such that it can be operated as simply and conveniently as possible and is secure, provision is made for the storage compartment cover to have two locked axes of rotation in its closed position. After one axis of rotation is released, a driving device automatically pivots the storage compartment cover in a damped manner into an open position.
Abstract:
A mechanism and method for operating a track-mounted door is disclosed. The mechanism includes a pair of side drums that are connected by first cables to the bottom of the door. The side drums are coaxially mounted on a shaft for simultaneous rotation with a pair of cable drums. The cable drums are connected to high pressure gas struts by second cables. Each second cable is carried around a shiv wheel that slides along a guide track as the second cable moves. Each shiv wheel is operatively connected to one of the gas struts. As the shiv wheel moves along the guide track toward the cable drum, the gas strut is charged. As the shiv wheel moves away from the cable drum, the gas strut is discharged. A standard electric motor and screw driven lift-arm is used to initiate the opening and closing of the door. The charged gas strut stores sufficient energy to overcome friction and gravity to assist the electric motor and lift-arm to open the door.
Abstract:
The device serves for storing energy. A spatial work range is defined by a displacement path upon compression of at least one spring of the spring storage. Along the work range in the working direction, at least two springs are arranged which are impinged in temporal succession upon compression and relaxation, respectively. For impinging the springs, at least one stationary retaining element and a mobile runner are provided. A spring loaded at a first point of time is immobilized in such a way that during a further displacement of the runner no further force is exerted by this spring between runner and retaining element. Reactivation of the immobilized springs is provided in temporal succession upon a reverse movement of the runner.
Abstract:
In a sliding door for motor vehicles, especially passenger motor vehicles, which for purposes of opening is lowerable into the vehicle body, the door body assumes in the lowered position, in which it receives the window in the lowered position thereof, an essentially vertical position. A coupling is provided for the simultaneous movement of the door body and window.
