Abstract: A self locking device that is used with a overhead, horizontally pivoted, door in combination with a power operated door opener is disclosed. The device comprises a latch mechanism that is activated by the movement of the door arm and a striker that receives a locking dog. A door arm, which is a part of the door opener, is the member that transfers the movement of the power operated door opener to the door. When the door arm is closing the door, the locking dog is free to interface with a striker. A striker mounted on the header of the door frame receives the locking dog and keeps the door from being forced open which can be done by breaking the door opener mechanism. The latching dog is released by the door opener mechanism with the reverse movement of the door arm and therefore the door is moved to its open position.

Abstract: When a driver inserts a key into a cylindrical lock-type outside door switch and rotates it clockwise or counterclockwise, a slide door for an automotive vehicle is opened or closed automatically by motor power from the outside of the vehicle. Additionally, when the driver inserts the key into the outside door switch, and rotates it to an open position, the slide door is unlocked automatically before being opened; when the driver extracts the key from the outside door switch, the closed slide door is locked automatically. A motor is mounted on the slide door and a power supply is applied to the motor by means of a current collector. A pinion and rack are also mounted on the slide door to open or close the door. Such structure allows the slide door to be opened or closed manually or automatically.

Abstract: An improved automatic garage door opener system is described, the delay linkage in the motorized door opening mechanism which enables actuation of latch closures for improved security and also provides improved shock cushioning in the system.

Abstract: A latching device for a security gate of the type used at the entrance of subterranean garages for apartments or condominiums or secured storage rental areas is disclosed which is mechanically actuated by operation of the motor drive system to open the security gate. The latching device effectively prevents the security gate from being forced open, and in one embodiment includes a mechanism for preventing manual disengagement of the latch from attempts to force the gate laterally until the latch disengages. The latching device of the present invention is substantially cheaper than other security gate locking devices, as well as being highly reliable and wear-resistant.

Abstract: A device for securing the locked position of a motor-vehicle door activated by a rotating post and that is locked or unlocked by raising and lowering the post has a disk attached to the post and a rotating support in the form of a double-armed lever mounted below the disk on a stationary section of the frame so that the support can be displaced into a position in which the disk rests on the top of one of the lever arms. The axis of rotation of the support is positioned on the frame section and lies in a plane that is perpendicular to the direction in which the rotating post is raised and lowered. The bottom of the second lever arm of the support rests on and is forced by a compression spring against a stop on the frame section and the bottom of the first arm of the support has a recess. A rotating locking element, which is also a double-armed lever with two support surfaces on one arm, engages the recess.

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 closure assembly especially adapted for use with the mould of cheese block forming machines, includes structure defining an opening and a closure member mounted to the structure for movement to and from a position in which it closes the opening. Co-operable locking means on the structure and closure member include a first element fixedly mounted to a shaft for rotation with the shaft, which is in turn rotatably supported on the closure member, and a second element defining a seat for the first element in a particular rotational position of the shaft. Seated engagement between the elements at this position physically locks the closure member in its closed position. Drive means coupled between the structure and the shaft is reversibly actuable to execute a first motion in which it drives the closure member from an open condition to its closed condition and then a succeeding second motion in which it causes rotation of said shaft to effect seated engagement of the co-operating locking means.

The apparatus comprises a shiftable member as for example, a plate which is mounted on the gate and is shiftable with respect to the side being hinged and the side thereof being located proximate the stationary member when in the closed position. A rod mechanism which is preferably comprised of a plurality of rods is operatively connected to a source of power, as for example, an electric motor, and this rod mechanism is also connected to the shiftable plate. When the motor is energized, the rod mechanism causes the gate to shift, either from an open position to a closed position, or otherwise, from a closed position to an open position.

The solenoid assemblies are interiorly secured at the door frame sides with the housings thereof permanently projecting across the clearance spaces between the door frame and door and interiorly overlapping the door with the solenoid plungers projectable therefrom in this overlapping positioning into aligned latch members secured interiorly of the door.

Abstract: What follows is a description of a mechanism for displacing structurally related component parts of a larger assembly of parts relative to each other. The component parts are typically locked together into the larger assembly and the mechanism is designed to first unlock the component parts and thereafter produce the relative displacement of the component parts. The mechanism is also designed to reverse the noted procedure and first produce the relative displacement followed by locking of the component parts. The procedure is effected using a single actuator and a continuous operation.

Abstract: A boom gate comprises a first-class lever counterweighted at one end adjacent to which is the lever fulcrum. The fulcrum is displaceable lengthwise of the lever through a short distance sufficient to cross the center of gravity of the lever. This movement is controlled by a mechanism and the boom lifts automatically under its own weight when the center of gravity is passed. The advantage of such a system is that the effort required to raise the boom is very little and the use of high-torque equipment is unnecessary so that the boom gate can be cheaply made. Ways of displacing the fulcrum using pneumatic pressure, a handle or an electric motor are described. Also a double-sided boom gate is described.

Abstract: A driving and locking mechanism which employs pivoted links for coupling and transmitting motion between driving and driven members. During motion, the links are constrained to a particular mutual position for transmission of driving forces, but at one end of the range of movement, the constraint is removed and the links pivot so that one link comes into normal or over-normal contact with an abutment and so locks the driven member in position. Forces on the driven member will not move it (except in the case where the abutment is resilient to allow limited movement of the driven member in the "locked" position) and movement of the driven member can only be accomplished by movement of the driving member. Thus a separate locking or latching mechanism is not required. The mechanism is particularly applicable to sliding doors, such as those of railway vehicles, where the door needs to be locked or latched in the closed position against forces applied to the door to tend to open it.
