  • Publication number: 20090267356
    Abstract: What has been developed is a keyless door lock that prevents young children from opening doors their parents or caretakers do not wish them to open. The lock is a bolting mechanism type lock or a latching type lock having no keyed lock access side to it, but rather, a means for locking and unlocking the lock, such as a knob, on one or both sides of the door that when turned, unlocks the door. The lock is positioned within the door at a height that is unreachable by small children. The lock is useful for locking doors internal to the home (e.g., doors to medicine closets, cleaning supply closets, garage doors, doors at the top of stairs) as well as doors that provide access to the exterior of the home and therefore access to leave the premises of the home without supervision. Adults and older children, however, are never locked in or out of the room or house as no key is required for operating the lock, merely the turning of a knob.

    Abstract: A two point lock includes two pivotally mounted security hooks having sliding faces that engage sliding faces of a spring-loaded mishandling pin when the mishandling pin is vertically extended and the security hooks are rotatably retracted. The mishandling pin is vertically retracted when it abuts a jamb. When the mishandling pin is vertically retracted, the sliding faces disengage so that the security hooks can rotate to lock onto a striker on the jamb. Thus, the mishandling pin prevents the security hooks from being slammed into the striker before a door or a window is fully closed.

  • Patent number: 7204526
    Abstract: A hood latch assembly includes a safety lever that is operative in conjunction with the movement of a latch plate so as to ensure a sufficient space between the safety lever and a hood. Namely, the safety lever is arranged in a folded condition when the latch plate constrains a striker of a hood, i.e. the hood is securely closed by the latch assembly. The safety lever is tilted up into an upright position only when the striker becomes freed from the constraint of the latch plate. Such an arrangement of the hood latch assembly provides a sufficient space between the safety lever and the hood to reduce any impact on a human body when a pedestrian collides with a hood of the vehicle.

    Abstract: There is disclosed a flange or pressure vessel closure device and method for deheading a coke drum. The coke drum deheading device has an annular retaining element spring biased from a lower flange of a coke drum, and a plurality of hooks which extend from the retaining element to engage a cradle holding the bottom head against the flange. When it is desired to disengage the head from the flange, the hook retaining element is moved by a first set of cylinders toward the flange to release tension from the hooks so that they can be disengaged from the bottom head by pivoting them outwardly using a second set of cylinders or other hook pivoting means. The bottom head can then be disengaged from the flange, lowered and moved laterally away from the coke drum on a hydraulic table.

  • Patent number: 5062668
    Abstract: A safety door lock for a door of an electrical appliance includes a longitudinally displaceable detent bolt mounted in a door of an appliance, a door lock housing having an opening receiving the free end of the detent bolt, and a longitudinally displaceable switching slide that having a stub end adapted to engage with the free end of the detent bolt. After engagement, further longitudinal displacement of the detent bolt causes movement of the switching slide to its "on" position. A biasing mechanism urges the switching slide toward an "off" position in which a detent mechanism latches the detent bolt in a locking position upon insertion of the detent bolt in the door lock housing. The detent mechanism includes a releasable locking latch which clamps the switching slide in the "on" position.

  • Patent number: 5004280
    Abstract: A power striker for door latch employed on the sliding side door of a van type vehicle includes a power driver rotary drive member which upon rotation through 180.degree. is operable to drive a slide member in linear movement between opposite end limits. A striker pin may be mounted directly on the slide or coupled by linkage to the slide to be located in a ready position when the slide is at one end limit and in an actuated position when the slide is at its other end limit. When in its ready position, the pin is latched to the closing door before the door reaches its fully closed position. The pin is then driven to its actuated position to power the door to its fully closed position against the resistive force exerted by the compressible door seal. The rotary to linear drive coupling develops a sinusoidally increasing door closing force during the final door closing movement and provides a positive retention of the striker pin in its ready and actuated positions.

  • Patent number: 4826224
    Abstract: A latch assembly for securing a microwave oven door comprising two latch pawls engaging latch hangers, a vertically reciprocable or movable member having an elongated hole, a rack and two spaced legs, a spring-biased pinion contacting with a push-button. The force applied by the spring bias facilitates closing and opening the door. Upon pushing a button which rotates the pinion counter-clockwise, thereby reciprocating the movable member having the rack upwardly to disengage the latch pawls from the latch hangers.

  • Patent number: 4664431
    Abstract: For use with a container with a removable cover at the top opening, at least one pair of cover tightening members are pivotally linked with each other and are mounted to the cover so that they can be operated to tighten the cover to the container or release it from the container. Specifically, each of the tightening members has an internally threaded central bore through it for accommodating its operating member which is also threaded to engage the central bore. The tightening member further includes stationary or fixed pawls at both ends thereof that engage or disengage with the flanged lateral sides of the container. Thus, when the operating member advances through the central bore, the pawls are disengaged from the flanges to allow the cover to be removed from the container, and when operating members are retracted, the pawls are made to engage the flanges to tighten the cover to the container. In either case, one tightening member is operatively associated with the other by means of the pivotted links.

  • Patent number: 4457146
    Abstract: A door lock for sliding doors of trucks, vans and the like includes an exterior handle assembly and an interior handle assembly for actuating components carried in an interior housing assembly. The components include a pair of rotary latch bolts projecting through openings formed in opposite sides of the housing assembly. A pair of strikes are carried on spaced portions of a vehicle wall at locations on opposite sides of a vehicle access opening which is controlled by the door. The door is movable between a latched-closed position wherein one of the latch bolts latchingly engages one of the strikes to hold the door closed, and a latched-open position wherein the other of the latch bolts latchingly engages the other of the strikes to hold the door open. A thumb-operated lock control slide is carried by the housing assembly and provides one means for locking and unlocking the lock from inside the vehicle.
