Abstract:
A sliding plug door comprising a door member (10, 11) movable in relation to an opening in a structure of a vehicle between a closed position in which it at least partially occupies the opening and an open position in which at least part of the door member (10, 11) overlies the vehicle structure alongside the opening, comprising a first drive means (30, 31, 32, 33) for effecting a first movement of the door member inwardly and outwardly of the door opening, to and from its closed position; and a second drive (51, 52, 53, 54, 55) means for effecting a second movement of the door member laterally when it lies outwardly of the opening, to and from its open position.

Abstract:
A door drive system for a sliding door includes a pair of pulleys; a drive belt on the pulleys; a drive shaft engaged with the drive belt; a rotary motor for rotating the drive shaft to translate the drive belt; and a door drive arm for mounting on a sliding door and interconnected with the drive belt for driving the sliding door between open and closed positions; and a door drive control system including a position sensor for sensing the position of the sliding door, a controller responsive to the position sensor for setting the speed, torque and acceleration of the motor in the opening and closing modes, and an obstruction detecting device for enabling the controller to interrupt motion of the sliding door in the opening and closing modes upon detection of an obstruction in the path of the sliding door.
Abstract:
A control and regulation for doors equipped with a microprocessor control is disclosed. Besides the normal path of information transmission to the microprocessor control, a second channel of transmission is created in that a safety surveillance system receives the same safety-relevant information as the microprocessor control. The safety surveillance system is capable of recognising errors, for example, when the microprocessor control has not switched off the door, the safety surveillance switches off the door, annonces the error in the system to an error recognition unit, and immediately stops the motor and thus the door by means of a redundant switching-off unit. The safety-relevant functions may be both manually and automatically checked.
Abstract:
An electric strand gate has at least one electric strand thereacross. The gate comprises an actuator which moves the electric strand up along a hoisting rail from a closed position to an open position, thereby providing clearance thereunderneath for passage of livestock, vehicles and or the like through the gate. The gate may have shuttles travelling along the hoisting rail, each of which is connected to a respective electric strand. The rail and shuttles may be configured so that electric strands are closer together when in the open position, thereby maximising clearance thereunderneath whilst moving apart in the closed position, so as to maintain the full height of the electric fence. The shuttles and the rail may be further configured so that the electric strands are electrically disconnected in the open position.
Abstract:
A refrigerator, comprising an automatic door-opening/closing apparatus mounted on a refrigerator body for driving the opening and closing of a door. When opening the door, if a first obstacle detecting apparatus detects the presence of an obstacle in front of the door, then the automatic door opening/closing apparatus stops the opening of the door; when closing the door, if a second obstacle detection apparatus detects the presence of an obstacle behind the door, then the automatic door-opening/closing apparatus stops the closing of the door. This stops the movement of the door upon the discovery of an obstacle while opening or closing the door, thus preventing the door from being damaged by collision, and when the obstacle is a person, preventing physical injuries from being caused.
Abstract:
An autonomous vehicle assembly comprises a chassis assembly and a storage assembly. The chassis assembly includes a front chassis module and a rear chassis module that are selectively connectable to one another. The front chassis module includes a front wheel and an EBS assembly for steering the front wheel and the rear chassis module includes a rear wheel and a propulsion assembly for driving the rear wheel. An autonomous driving module is selectively connected to the chassis assembly and independently in communication with the EBS assembly and the propulsion assembly.
Abstract:
A garage door assembly includes a plurality of hingedly connected panels are configured to movably engage a pair of guide rails. The guide rails include a substantially straight lower portion and a curved upper portion, where the curved upper portion has a variable radius of curvature. This configuration allows for compact housing of the garage door panels when the garage door is in an open configuration, allowing for a more compact overall footprint within a garage.
Abstract:
A vertical pivoting gate operator for positioning a gate between an open position and a closed position is provided. The gate operator includes a motor drive assembly including a motor and a linkage assembly mechanically connecting a motor output to the gate such that in response to actuation of the motor, the linkage assembly transmits an opening force to positioning the gate toward the open position, and a closing force, for positioning the gate toward the closed position. A counterbalance assembly including a biasing member is operable to release stored energy against an input link to rotate a gate arm shaft so as to urge the gate toward the open position and to increase stored energy in response to rotation of the gate traveling toward the closed position to act against the gate as it approaches the closed position.
Abstract:
The invention relates to an overhead door for covering a door opening comprising a door blade (11) with a plurality of panels (17), said door blade (11) being movable between a vertical, closed position and a horizontal, opened or overhead position within a side frame (12) comprising double-sided a vertical track (13) and a horizontal track (14), connected by a connecting portion (15), respectively, and with a belt (20) or a chain associated with one side each of the said side frame (12) to lift the panels (17) from said vertical position to said horizontal position. To develop the stated overhead door in a way that the advantages of a high speed rollup door and an overhead door are combined, to offer an overhead door with a low space requirement, low maintenance requirements and a high speed closing possibility, the stated overhead door comprises driving means (27) for simultaneously driving a plurality of said panels (17).
