Abstract:
An emergency actuating device for a closing system of a movable part of a vehicle, in particular of a door, sliding door, flap or tailgate, having at least one energy store, a communication unit for wireless communication with an ID transponder, and an electronics unit for activating a lock of the movable part, whereby the lock of the movable part can be transferred from a locking position into an unlocking position or vice versa.
Abstract:
A door security device for preventing opening of a door. A first device includes a bar that seats against a doorframe on opposite sides of the door and a clamp that clasps a door latch and applies a force to draw the bar against the doorframe while pulling the door latch toward the bar. The door cannot be opened away from the bar. A second device has a bar that seats against a doorframe at the floor with a two plates that extend beneath the door and around to opposite sides of the doorframe. Removable pins or other locks obstruct the plates from sliding along the bar. The bar is tall enough that the door cannot pass over the bar, thus obstructing the door from opening inwardly. A closer cover slides over a mechanical door closing mechanism to be used alone or with the other devices.
Abstract:
A device for moving a movable furniture part, including a force accumulator such that by way of the fitted device the furniture part under action of the force accumulator is capable of being put in the opening direction of the furniture part, wherein in a tensioned position of the force accumulator the force accumulator is charged for the opening movement of the furniture part. The device has a locking assembly having a displaceable locking member for locking the tensioned position of the force accumulator, wherein the locking member in the tensioned position assumes a locking position which is unlockable. The locking member in the case of an unlocking procedure is movable from the locking position in a releasing direction, wherein a transmission installation by way of which a movement of the locking member is transmittable to a functional unit which is spaced apart from the locking member is provided.
Abstract:
A door opening and closing device for a refrigerator includes a door coupled to a main body, an opening and closing unit including a drive unit for generating rotational force by means of a motor and a door rotating mechanism for opening or closing the door, a device for measuring a back electromotive force generated from the motor, a power circuit connected for supplying power to the motor, a circuit for transmitting back electromotive force of the motor to the device, a control switch for selectively connecting the motor to the circuit or the power circuit, and a control unit for connecting the control switch to the power circuit when the motor is activated, and connecting the control switch to the circuit and opening or closing the door when the motor is deactivated, wherein the control unit closes the door when a predetermined back electromotive force is input to the device.

Abstract:
A driving mechanism is arranged such that at least a part is contained within a space corresponding to the external shape of a driving motor, that is, within a space corresponding to a distance in the radial direction of the driving motor. The driving mechanism comprises a pinion, a transmission gear, a ring gear that forms a fixed axis, and a carrier. The pinion is connected to a rotary shaft of the driving motor. The transmission gear has a disk gear portion that meshes with the pinion, and a sun gear portion that is located on the same side as the pinion with respect to the disk gear portion. The carrier has a planet gear and rotates with a drum.
Abstract:
A system for moving a barrier protecting a restricted area. A stationary linear induction motor moves the barrier by applying a magnetic field from the linear induction motor to a reaction fin attached to the barrier. The reaction fin has a rectangular beam or protrusion forming a groove on each side, which is engaged with guide members to guide the barrier. Holes are evenly spaced along the length of the reaction fin. Magnetic sensors sense the holes during movement of the barrier to determine the speed, position and direction of the barrier. A locking mechanism engages a pin into any one of the holes to lock the barrier in a fixed location. A heater is disposed within the rectangular beams or protrusions of the reaction fin to melt ice in cold weather environments. The system is operated by a main control logic that receives input data from the electronic sensors and controls the linear induction motor, heater and locking mechanism.
Abstract:
An electronically-activated roof access hatch is described that allows an operator to unlock the roof access hatch safely from the ground before ascending to the roof access hatch. The opening of the roof access hatch is controlled by a control panel that unlocks the roof access hatch and causes the roof access hatch to open.
Abstract:
An electric door operator for opening and closing one or a spaced pair of transit vehicle passenger doors for being mounted over an opening for the doors. A rotatable input shaft has an electric motor secured to the input shaft for driving the input shaft, a worm centrally positioned on the motor shaft, and an electric brake mounted to the input shaft at an end opposite of the electric motor. A drum cam lifts a pinion from a worm gear disconnecting the worm gear from an output gear train in an emergency.
Abstract:
A drive system for an entry/exit facility with at least one pivotably and/or slidably mounted door, ramp, tread or the like of a passenger transport vehicle, the system including at least one actuator or drive motor and a mechanical system driven by it and/or a gear unit for effecting the pivoting or sliding movement of the door, ramp, tread or the like, with an absolute value encoder for acquiring a momentary position during the pivoting or sliding movement, where an evaluation unit is configured to compare the momentary position with at least one reference position stored in a non-volatile memory of the evaluation unit in order to generate an output signal dependent thereon, and the absolute value encoder is flange-connected to a pin that fixes the pivoting movement of the door, ramp, tread or the like, and the gear unit includes a first reduction gear unit, a second reduction gear unit, and a controllable coupling is provided between the reduction gear units.
