Abstract: The door apparatus has a linear motor for applying a thrust to move a door, a lock device for performing a locking operation and an unlocking operation, and a control unit for controlling the linear motor and the lock device. Upon determining that the lock device is still in a locked state after a set time has elapsed from initiation of the unlocking operation, the control unit controls the linear motor to apply a thrust force to the door while again controlling the lock device to perform the unlocking operation. As a result, even when the locking pin and the lock hole are misaligned to such an extent as to interfere with the unlocking operation, the unlocking operation can be performed without an increase in a thrust output by a solenoid of the lock device, the solenoid can be prevented from overheating and the size and weight of the solenoid can be reduced.

Abstract: In a device for opening and closing a window, a casement is moved between a closed and open position with respect to a stationary frame. This is done by a longitudinally displaceable toothed rack, which transfers the longitudinal movement into a movement of the casement by a hinge rod. In order to obtain a device which is easy to operate, it is proposed that in addition to the first toothed rack co-operating with the casement, a second toothed rack is provided in the frame which changes closing elements located on the frame between a latched position holding the casement and an unlatched position releasing the casement, by a closing rod. Although both toothed racks are longitudinally displaced by the same actuating element, as a rule only one of the two toothed racks is coupled to the actuating means while the other is uncoupled and stationary.

Abstract: An automatic operating system for swinging doors which is controlled by the user by means of a miniature, hand-held radio transmitter having a single operating pushbutton.Depression of the pushbutton results, sequentially, in the retraction of the deadbolt, the retraction of the main latch, and the opening of the door. The door then remains open until the pushbutton is again depressed, whereupon the main latch is extended, the door is swung to its closed position, the deadbolt is extended into its associated recess in the doorjamb, and the air pressure in the automatic door operating system is bled to atmospheric level, resetting the system to its normal or quiescent state.

Abstract: Apparatus for causing a rotatable actuator to effect unlocking of a window latch and then to swing the window sash open when the actuator is rotated in one direction. When the actuator is rotated in the opposite direction, it first causes the sash to swing closed and then causes the latch to lock and hold the sash in its closed position. In one embodiment, the actuator is effective to swing an arm and shift a slide for purposes of moving the sash and operating the latch. In another embodiment, the actuator rotates a lead screw which advances nuts for moving the sash and operating the latch.

Abstract: A child's toy oven comprises a housing having a baking chamber therein. An access opening is provided in a wall of the housing for communicating with the baking chamber. A slidable access door is positioned on a wall of the housing to open and close the access opening. A latch cooperates with the access door to prevent inadvertent opening of the slidable access door. The latch is pivotally secured on the access door and a stop shoulder on the housing is adapted to engage the latch to retain the access door in position closing the access opening. A spring is positioned between the latch and the access door for biasing the latch into position for engagement with the stop shoulder to preclude movement of the access door to unblock the access opening. A tray actuator external of the housing is provided to engage the latch to release it from engagement with the stop shoulder to permit movement of the access door by the tray to open the access opening and allow the tray to enter the baking chamber.

Abstract: A garage door opener with solenoid latches is provided with a circuit for energizing the coils of the solenoid latches with power from a 24-volt step-down transformer, either as 120 volt power is applied to a motor to move the door in response to detection of an initial surge of current or as a manual or radio controlled command switch is actuated. In either case, current at a higher level is applied initially to pull in the armature locking pins of the solenoid latches, and thereafter at a lower hold-in level. A transformer with a single turn primary winding or a Hall-effect device may be used to detect the initial surge of current to the motor and in response thereto pull in the locking pins. Thereafter, hold-in current is applied as long as current to the motor is sensed.

Abstract: A swinging gate operating mechanism having a crank and links which withdraw and insert the locking bolt as the linkages pass over center, and aligning linkage centers to allow the mechanism to rotate freely with a pair of indexing links to prevent the gate from rebounding out of the latch as the bolt impacts the jam post.

Abstract: By providing two separate units for actively opening and closing a door of an automobile, safe and reliable door opening and closing operation may be achieved. The first unit is operated to open the door in a normal way and closes the door to its not fully latched state while the second unit completes the door closure operation by closing it to the fully latched state, thereby reducing the unfavorable influences arising from the impact which is otherwise unavoidable for complete closure of the door.

Abstract: A door and latch sequencing mechanism includes a door member 10 hingedly mounted along one edge to an aperture defined by body walls 12, for movement between open and closed positions. The door member 10 pivotally carries a latch 13 for movement between latched and unlatched positions. A crank member 16 turnable about a fixed axis is connected by a first connecting rod 18 to the door member and by a contracting linkage 19, 20, 21 to the latch member. The first connecting rod, contracting linkage and crank member are arranged so that turning of the crank member in the appropriate single sense sequentially(a) maintains the door member in its closed position or moves it to a temporary position remote from the open position,(b) unlatches the latch, and(c) opens the door member.
