Abstract:
A door closing apparatus facilitates simultaneously opening of a pair of sliding doors by pulling a manual release wire. Specifically, by pulling the manual release wire, a belt 82 fixed to the manual release wire moves with belt pulleys and two hooks to contact and move respective movable frames to the opening directions thereof. Due to these movements, permanent magnets 31A, 31B rotate, through respective racks to release the holding of the closed doors. Thus, the sliding doors can be opened manually.
Abstract:
An automatic opener for a sectional door includes a drive unit mounted adjacent to a door drive shaft and having a reversible motor, a gear linkage for translating rotation of the motor drive shaft into rotation of the sectional door drive shaft, and a clutch which permits the gear linkage to be manually temporarily disengaged from the motor drive shaft. The drive unit is supported within a housing that is connected to an adjustable wall bracket mounting base which itself is fixed to a wall adjacent to the sectional door. A spring-biased lever attached near a lower end of the sectional door pivots in response to slack in a door cable to automatically lock the door when it is completely shut. The locking mechanism automatically unlocks the door either when the drive unit is actuated to open the sectional door or when the clutch is utilized to disengage the gear linkage from the motor drive shaft.
Abstract:
Control systems including control circuitry and optional communications systems for operating a sliding power-operated member of an automotive vehicle. A powered sliding door in an automotive vehicle, such as a van, moves along a predetermined path of travel between a closed position and a fully open position relative to the body of the vehicle. Such a sliding door may be provided with one or more electrically-operated actuators for performing functions associated with the door, such as power opening and closing the door, power unlatching the door, power locking and unlocking the door, and power clamping and unclamping the door in a soft or low-momentum manner. The invention is directed toward improved control systems and circuitry for operating such power-sliding door systems. One such control system employs a wireless communications link between the door and body, which is preferably implemented using radio frequency communication signals containing digitally encoded control signals. Control circuitry is preferably provided in the body and the door of the vehicle for supervising and carrying out the foregoing functions in an orderly manner in response to requests generated locally at the door or remotely by the driver from the console of the vehicle. A second, simpler, control system provides electrically-actuated mechanisms for unlatching the door and operating the door lock without the use of either a wireless communication system or a retractable electrical cable interconnecting the sliding door to the vehicle body.
Abstract:
A safety coupling device for manual disengagement of a drive mechanism to the counterbalance shaft on an overhead garage door mounted in a garage structure. The device includes a first annular hub mountable on the counterbalance shaft in a fixed position with relation to the counterbalance shaft. A second annular hub with a drive sprocket connected to a motor drive is rotatably and slideably mounted on the counterbalance shaft. At least one pin or protrusion is provided on one of the hubs so that the protrusion mates with at least one hole for accepting the pin or protrusion on the other hub. When the second hub is in a first position the pin or protrusion on one hub resides within the hole of the other hub and thus engages the two hubs and permits power from the motor drive to be transmitted to the counterbalance shaft in order to raise or lower the door by the motor drive. When the second hub is in a second position the pin or protrusion is withdrawn from the hole and the hubs are disengaged. Disengagement of the hubs allows the second hub to free wheel on the counterbalance shaft and thus disconnects the motor drive mechanism, allowing manual raising or lowering of the garage door. A lever is used to move the second hub between the first position and the second position in order to disengage or engage the hubs as desired.
Abstract:
In a window with a frame of extruded profile members the exterior side of an edge portion of a thermo pane is supported by a first flange portion of the profile member and the inside by a glazing bead connected with the frame profile member. The main frame mainly consists of wood profiles, the exterior sides of which are covered by weather-resisting coverings. A hinge member at the top of the window comprises an edge portion (28) of an extruded profile member (27) forming a hinge pivot firmly connected to the main frame portion (20) at this side and a hook-shaped wall portion (6) of the opposite frame profile member (1) forming a hinge blade. At one of the other sides of the window an arrangement is provided to ensure engagement of said hinge pivot and hinge blade forming portions in the closed position of the window. Such arrangements may comprise a sliding block (31) arranged displaceably in a track in the frame profile member, which block can be moved between a position opposite a retaining device anchored in the main frame structure for permanently securing the frame in case of a fixed window and a position in which it can be connected to a motion transfer member which is guided in a recess in the wood profile of the main frame for complete accommodation of the motion transfer member in the closed position of an openable window.
