Abstract: A fastening mechanism for a cover, door or the like, hinged on a body, frame or the like, wherein a locking element is fixedly attached to the body, frame or the like. The cover, door or the like supports an actuating element which controls a locking mechanism that can be disengaged from the locking element during opening and engaged with the locking element during closing. To assure an easy operation of such a fastening mechanism, while at the same time assuring locking, the actuating element can be moved from the closed position to the open position by a pulling force acting generally perpendicularly relative to the connecting plane defined by the cover, door or the like.

Abstract: A quick release lock for a cover is provided. The cover may be a manhole cover for closing onto a manhole ring having a radially extended flange. The quick release lock mainly includes several angularly equal-spaced cross-shaped slots provided on the cover to communicate with through holes below them, and catch elements, push elements, and cotters in the same number as that of the cross-shaped slots. The catch element each is pivotally connected to and between two fixing plates provided at two opposite sides of each through hole. The cotter each is positioned in one cross-shaped slot and extended down into she through hole. The push element each is screwed on a bar portion of the cotter below the cover. When the cotter is depressed, the push element radially pushes the catch element outward to engage with a lower edge of the flange on the ring member and thereby firmly locks the cover to the ring member.

Abstract: A latch assembly for installation in a recess along a side edge of a wing element, for covering or uncovering an aperture, the latch assembly being adapted to hold the wing element in a closed position. The assembly includes a housing having at least one wall, at least one espagnolette bolt and an espagnolette rod. The espagnolette bolt is slidingly arranged in the housing between a first open position, in which the espagnolette bolt is retracted into the housing, and a second latching position, in which the espagnolette bolt projects from the housing to engage with a catch. The espagnolette bar is operatively connected to the espagnolette bolt for maneuvering the espagnolette bolt between the first open position and the second latching position. A latching pin is arranged for displacement with the espagnolette bolt, during movement of the espagnolette bolt from the first open position to the second latching position and back.

Abstract: Locking devices for locking two components that move relative to one another such as a housing and a cover are disclosed. The locking devices have two catches disposed on one component and opposite to one another and symmetrically with respect to a stop disposed on the second component and arranged in a plane of symmetry between the opposing catches. The catches have hook ends facing the plane of symmetry and the two catches are connected to a common shaft at the ends of the catches facing away from the hook ends. The common shaft is disposed in the plane of symmetry and is movable within the plane of symmetry toward and away from the stop. The shaft is arranged on a spindle disposed in the plane of symmetry or parallel to the plane of symmetry and engaged with a motor-driven gear to effect movement of the shaft. The catches have longitudinally-extending guide elements whose longitudinal axis does not run parallel to the plane of symmetry.

Abstract: A lock system for a container with a movable closure or lid. The lock system includes a pivotally mounted latch member, a corresponding rigid latch member which interlocks with the pivoting latch member when the closure is closed, and a push-button lock mechanism having a shoulder portion which engages and displaces the pivoting latch member, thereby permitting the closure to be opened, when the lock mechanism is in its "unlocked" position and the push-button is depressed. The pivoting latch member includes a pair of plates slideably coupled to one another, one pivotally mounted in the container and the other supporting a cross-member which engages the rigid latch member. The pivoting latch member has a slot through which the shoulder portion of the lock mechanism passes (without engaging or displacing the latch member) when the lock mechanism is "locked".

A plurality of wedge bars are mounted for horizontal sliding movement on the outer surface of the door toward and away from the corresponding swing hook and are each provided with a cam surface thereon. In the operation of the instant apparatus, the wedge bars are extended toward the respective swing hooks such that the cam surfaces on the wedge bars engage the cam surfaces of the swing hooks thereby rotating the swing hooks against their spring bias.

Abstract: Latching system hardware for luggage articles such as attache cases and the like includes an elongated latch console for attachment interiorly to one section of the article, an actuator assembly for manually operating the console latches, and a lock assembly for selectively locking the latches. The hardware can be assembled in different configurations and operating modes and the console can be used with different types of lock and actuator assemblies so that diverse latching systems can be developed from the same basic console components.

Abstract: A latch mechanism is shown which utilizes a pair of latch dogs pivotally mounted on a base member. Each of the dogs has a curved end region which is adapted to contact a curved work surface of an associated stop member. The dogs are pivotable between a release position in which the curved end regions are apart from the work surfaces to allow relative movement between the base member and stop member and an engaged position in which the curved end regions contact the work surfaces. A positive locking action is achieved by providing the dog end regions with a radius of curvature which matches the radius of curvature of the stop member work surfaces, but offsetting the center point of the radius of curvature of the dogs from the pivot points of the dogs. In this way, the end regions and work surfaces fully mate in the engaged position, but are pulled fully apart when moving to the release position.

Abstract: A container-locking mechanism for locking two perforated overlapping sections of a carbon or the like. An outer tubular member is fitted into the aligned holes in the sections and formed at one end with a radially outwardly extending flange. An inner tubular member has a plurality of circumferentially spaced tapered portions. The inner tubular member is locked in a position when fully inserted in the outer tubular member. The outer tubular member has a plurality of arms arranged to be engaged and forced radially outwardly beyond the outer peripheral surface of the outer tubular member, by the tapered portions, when the inner tubular member is inserted into the outer tubular member.

Abstract: Locking mechanism having a casing including a pair of spaced support plates of similar size and shape. The support plates have identical, spaced, congruent, T-shaped tongues along their front edges. When installed in a door, the tongues extend beyond the edge to engage a strike in the door frame. A pair of bolt members are pivoted in the space between the support plates and are movable between an extended, closed position engaging the strike to a retracted, open position not engaging the strike. A slide rod engages the bolt members and is rotatably and reciprocally journaled between the plates. The slide rod has a transverse arm portion adapted to be connected to one or more manual locking elements in the vehicle door to turn the rod between locked and unlocked mode positions. A slide actuator lever is pivoted to the casing and is engageable with the slide rod arm portion to turn it between locked and unlocked mode positions.

Abstract: A dual latching mechanism is provided for latching two spaced locations of a flexible lid to a pair of similarly spaced anchors of a compartment to which the flexible lid is movably mounted. The latching mechanism has two latches mounted on the lid by housings each including a pawl pivotally mounted which is spring biased for movement, when released, to an anchor release position and a blocking dog which is spring biased to a pawl blocking position for locking the pawl to its respective anchor. The latches are interconnected by a latch control which includes two rigid links each link having its outer end connected pivotally to a blocking dog and each having its inner end connected by way of an actuator pin to a key operated lock cylinder which is mounted on the flexible lid. The rigid links are connected so as to maintain axial rigidity for operating the two latches concurrently while having the required flexibility necessary to operate two latches on a flexible lid.
