Abstract:
A door-opening assisting structure eliminates exclusive operating members and provides enhanced operability and reliability by operating in sync with the opening of a door. A passive member connected to a door closer, urges the door to move in the door-closing direction, rotates forward and backwards accompanying the opening and closing of the door. This moves transmission members forward and backwards in the direction of the opening and closing of the door, respectively. An opening spring urges the transmission member to move in the same in the direction as the opening of the door. The spring is locked in a release-pressure-storing state after accumulating release pressure as a result of the movement of the transmission member. The opening spring applies release pressure due to the rotation of the passive member within the predetermined angle region of the passive member when the door is beginning to open, and then is locked in the release-pressure-storing state.

A door operator includes a housing; first and second pressure compartments; an unpressurized reservoir chamber; a drive unit disposed in the housing and coupleable to a door via an output shaft, the drive unit being associated with the first pressure compartment; a hydraulic pump in hydraulic connection with the first and second pressure compartments; a motor in driving relationship with the hydraulic pump; a spring force accumulator disposed in the housing, the spring force accumulator being associated with the second pressure compartment and coupled to the drive unit; a hydraulic circuit connecting at least one of the first and second pressure compartments with the hydraulic pump; and a fire-protection/releasing device disposed between the hydraulic circuit and the unpressurized reservoir chamber.
Abstract:
A door operator includes a first component having a right-hand thread, a second component having a left-hand thread, and a plug-in or rotatable coupling having two complementary threads. The first and second compartments are interconnected to each other by the coupling when the right-hand thread of the first compartment and the left-hand thread of the second compartment engage the respective complementary threads of the coupling.
Abstract:
An automated garage door closing device for a remote controlled overhead garage door wherein the device is mounted on one of a pair of parallel tracks receiving rollers suitably mounted on the outer edges of the door panels, the device including a switch housing containing a switch for the leading edge of the door, and a circuit located in a second housing adjacent the garage floor and including an interval timer acting to close the door after a predetermined period of time, an audible alarm which is activated upon the garage door reaching the fully open position, a switch deactivating the entire unit when the garage door is deliberately to be left in the fully open position, and a flexible switch arm extending through the switch housing to a position to engage the upper edge of the garage door panel and acts to activate the automated closing device. A recycle delay circuit in the timing circuit acts to deactivate the unit upon interruption of the door closing operation if door movement is reversed and returned to the open position, and a sensor providing a sensor beam adjacent the garage floor to measure the time interval of interruption of the sensor beam to determine if a vehicle has exited or entered the garage or a person or animal has interrupted the beam. Also, a carbon monoxide detector is inserted in the circuit to provide activation of the door opening cycle if the level of carbon monoxide reaches a dangerous level.
Abstract:
A drive assembly moves a vehicle closure panel from an open to a closed condition. The drive assembly has a housing and a motor mounted on the housing. A drum and gear assembly is rotatably mounted on the housing. The drum and gear assembly has a drum having a helical groove, a gear in driving engagement with the motor, and a spring biasing the drum in a winding direction relative to the gear. The drum and gear have a lost motion connection therebetween. A cable has an end connected to the closure panel and an opposite end connected to the drum about the helical groove in the winding direction. The drum rotates in the winding direction relative to the stationary gear as the closure panel is manually moved from the open to the closed condition with the spring maintaining a cable tension. The drum and gear rotate together in the winding direction upon energizing the motor effecting powered movement of the closure panel to the closed condition. The motor is afterwards energized in an opposite direction counter-rotating the gear relative to the drum back to a start position.
Abstract:
The present invention provides a control apparatus for automatic sliding doors that can be used with a plurality of door brands and models. The invention includes a control box and an idler pulley mounted to the door header. Both the control box and idler pulley can be mounted on a variety of door models by means of specific header brackets that are configured for each door model. The control box also provides a universal signal interface that can interpret sensor signals from a plurality of door models. A drive belt revolves on the idler pulley and is moved by a motorized pulley controlled by the control box. At least one belt bracket is fastened to the drive belt with a belt clamp, wherein the belt bracket is attached to a sliding door panel. Like the control box and idler pulley, the belt bracket can be used with a variety of door models and is attached to the sliding panel by means of a door bracket that is specific to the door model in question.
Abstract:
A waterproof power window apparatus comprises: a driver-seat switch unit; an other-seat switch unit; and a bus line allowing communication to be established between the driver-seat switch unit and the other-seat switch unit. The driver-seat switch unit has: a first controller; a first driving unit for opening and closing a window at the driver seat in a window-sliding operation; an other-seat-window-opening and closing switch; a first submergence-detecting unit; and a first power-supply unit connected to the bus line and provided with a control terminal connected to the first control unit and the first submergence-detecting unit. The other-seat switch unit has: a second control unit; a second driving unit for opening and closing an other-seat window in a window-sliding operation; a second submergence-detecting unit; and a second power-supply unit connected to the bus line and provided with a control terminal connected to the second control unit and the second submergence-detecting unit.
Abstract:
The present application discloses automatic door assemblies and swing operators therefor. One aspect of the disclosure provides a swing door operator that has spring return breakout and from motor driven opening. Another aspect of the disclosure provides a swing door operator that is non-handed with spring return from either direction. Another aspect of the disclosure provides a swing door operator in which spring force is transmitted to the operator output member via a cam structure.
Abstract:
In a power window device, a DOWN switch has first and second switches in a power window circuit located in a door for a window of a passenger's seat. A normally-closed contact of the first switch and a remote UP terminal of the power window circuit to which an UP signal is applied from a power window circuit provided near the driver's seat are connected. A normally-closed contact of the second switch and a remote DOWN terminal of the power window circuit to which a DOWN signal is applied from the power window circuit are connected. When the DOWN switch is manually operated, a signal supply line to which the UP signal and the DOWN signal are applied and a power supply line to which a power source is connected are electrically disconnected. As a result, the power window device is operable even when the signal supply line is grounded due to submerging in water.
