Abstract: The present invention includes a latch assembly, such as maybe useful for SMIF pods. SMIF pods are in general comprised of a pod door which mates with a pod shell to provide a sealed environment in which wafers may be stored and transferred. During wafer storage and transport, the pod door is typically held affixed to the pod shell by a latch assembly. When it is desired to separate the pod door from the pod shell, each latch must be actuated outwardly, to withdraw each engagement portion from the pod door, at which time the pod door may be separated. The present invention includes an improved such latch assembly.

The door catch mechanism has an unlocking lever which, when engaged with a bolt element, is ready for contact opposite a trigger element of the tensioning device so that following the unlocking of a bar/drive rod locking unit with the lock unit, the bolt element can be moved from the engagement position to a release position by deflection of the unlocking hammer.

Abstract: A lock assembly comprising a housing, a control mechanism, one pin or two pins supported by the housing for shifting movement of the pin or of the two pins in a direction transverse to direction of movement of the control mechanism between a locked position and an unlocked position and a spring for each pin for enhancing the shifting movement of the corresponding pin toward the unlocked position and for automatically returning the corresponding pin toward the locked position upon release of the control mechanism. When the control mechanism is pushed manually, the pressure which is exerted upon pushing the control means compresses the spring around the pin or two pins which each shifts in a direction transverse to direction of movement of the control mechanism between the locked position and the unlocked position. Meanwhile, shifting of the pin or of the two pins permits the sliding of a cut-out section of the control mechanism until the pin or pins strike against the cut-out sections of the control mechanism.

Abstract: A deadbolt lock system is provided for a swinging door which prevents movement of the deadbolts from a locked position to an unlocked position when the door is open. Movement of the deadbolts from an unlocked to a locked position when the door is opened is prevented by a slide plate which is locked into a deadbolt deactivating position by a plunger which is biased outward when the door is opened. The system also provides for an unlocking of the deadbolts and an opening of the door with a single rotation of the inside handle.

Abstract: The invention is a mortise lock constructed for very simple conversion between multiple functions and left and right hand openings. The lock can include or omit retraction of the latch bolt from either side with a key, permanent locking of either side's retractor, removal of the stopworks, simultaneous retraction of the latchbolt and deadbolt, or locking the retractor when the deadbolt is thrown. All of these conversions are accomplished without opening the case cover by the insertion or removal of screws or parts through holes in the cover or case, with the screws either stopping a part from moving or providing a catch upon which a part acts. The changeover between right and left handed openings is accomplished through the backplate with removal of only the armor plate, by removing, reversing, and reinstalling the latchbolt.

Abstract: A security door replacement for increasing the security of homes or other structures includes a security door locking mechanism having a piston centrally located parallel to a longitudinal axis of the door. The piston has wedge shaped components on either end which interact with four locking arms.

The actuator has two arms, respectively, to move the lock bolt from its extended to its intermediate position and, at the same time, to engage the remote lock operator for moving it to the remote lock release condition, where it can be engaged by the retainer.

Abstract: A nuclear power plant fuel transfer tube quick operating remote closure device (10) comprised of a reducing ring (20) and a cover assembly (60). The reducing ring (20) is bolted to the transfer tube housing flange (12). Rotation of a chuck key advances jaws on the cover assembly (60) which feed closure latches (78) into a groove (40) on the reducing ring (20). The upper surface (80) of each latch (78) has a bevelled surface (82) corresponding to a bevelled surface (42) of the groove (40). As the latches (78) engage the groove bevelled surface (42), the entire cover assembly (60) is uniformly drawn toward the reducing ring (20). Machined seal faces (13, 30, 44, 68) and O rings (36, 74) provide a fluid and air tight seal between the transfer tube housing flange (12) and the sealing ring (20) and between the cover assembly (60) and the sealing ring (20).

Abstract: A linear preload fluid power operated latch has two coaxial pistons, one slidable inside the other and the other slidable within a cylinder. The one piston slides inside the other to cam dogs which are slidable in slots of a nose which is secured to the other piston so as to engage an undercut in a cup in which the nose is received. After the dogs are engaged in the cup, which secures the latch, both pistons are retracted to apply a linear preload force between the two bodies being latched. In one embodiment, the pistons are moved in both directions under fluid pressure and in another embodiment, both pistons are returned by compression springs. In either case, the cup is drawn closer to the cylinder with a certain preload force, to latch a body to which the cup is attached to a second body to which the cylinder is attached with that preload force.

Abstract: A safety door has safety bolts provided at two opposite peripheral edges of the door leaf. By a locking mechanism apparatus, the safety bolts can be shifted into assigned guideways in such a manner, that they protrude beyond the corresponding peripheral edge of the door leaf in a locked position and are accommodated in the door leaf in an unlocked position. The locking mechanism apparatus has a slide rod which can be shifted in its longitudinal direction essentially transversely to the guideways and with which the safety bolts are mechanically coupled. Precisely one safety bolt is carried in each guideway. The safety bolts assigned to the one peripheral edge and those assigned to the opposite peripheral edge are disposed offset to one another.

Abstract: An independent dual deadbolt locking mechanism for securing doors, windows or the like.

The bolts 12 are deadlocked by the action of a bush 26 fitted within a slot 24 in the bolts 12 and applying a transverse force thereto. The deadlocking of the bolts 12 serves to compress the door 4 shut.

Abstract: A door-mounted double-latch mechanism consists of two forwardly-sprung latching pawls which are adapted to engage a keeper mounted on the door jamb. One of the latching pawls, the secondary pawl, has a wider keeper-receiving recess at its forward end than does the primary pawl, so that the secondary pawl will snap behind the keeper before the primary pawl does. As a result, even if the door is not fully closed, the secondary latching pawl will nevertheless be engaged. Mounted on the inside of the door is a cam with a bent-up tab which is adapted to engage both pawls. When the cam is rotated in one direction the primary pawl is caused to retract. When the cam is rotated in the opposite direction the secondary pawl is caused to retract. Sandwiched between the two pawls is a spring-biased lever the primary purpose of which is to urge the door outwardly, ie., towards the open position.
