Abstract: A locking system for toolboxes, industrial cabinets and the like includes a push button operator assembly connected by at least one movable link to at least one latch mechanism configured to latchingly engage an associated striker to releasably retain a first structure (such as a closure) on which the striker is mounted in a closed position relative to a second structure (such as a cabinet) on which the locking system is mounted. The push button operator assembly has a button that, when unlocked, can be depressed to move the associated link to unlatch the latch mechanism from the striker, and that, when locked, is inoperable when depressed to move the link.

Abstract: A slam-capable, T-handle operated rotary latch has a pan-shaped housing for nesting the T-handle and employs a single rotary jaw that is releasably retained in its latched. position by a rotary pawl. The latch has spaced first and second side plates that sandwich the rotary jaw, the rotary pawl and a torsion spring that biases the jaw toward an open position. The pawl defines a release trigger which, when tripped, permits the jaw to be pivoted by the torsion spring to an open position. A compact arrangement of stop formations and independently pivotal operating arms is provided adjacent a backwall of the housing to enable the T-handle to trip the release trigger during forward pivoting of the T-handle and the operating arms in opposition to the action of a return spring, and to limit reverse pivotal movement of the operating arms and the T-handle under the influence of the return spring.

Abstract: A versatile slam capable latch mechanism that can be operated by one or more adjacent and/or remotely located operating devices to release a striker from latched engagement; that can be directly attached to an operating device such as a flush-mountable paddle handle assembly to provide a “stand alone” latch; that can be connected by one or more rod-like links to one or more remotely located operating devices such as push button assemblies; that can be connected by rod-like links to other similar latch mechanisms each arranged to be slammed into engagement with a different striker to provide a “plural point” latching system; and wherein one of the various types of operating devices that may be connected to a latch system that includes one or more of the latch mechanisms can be provided with a key operated lock to “lock” the system.

Abstract: A flush mountable operating assembly has paddle-type handle nested in a housing-defined recess for pivoting between non-operated and operated positions. An operating linkage for drivingly connecting the paddle handle to one or a plurality of adjacent or remotely located latch assemblies includes overlying first and second arm that are connected to the housing for pivotal movement about a common pivot axis. A lock cylinder is carried by the housing and is coupled to a connecting element for positioning the connecting element at selected locations along the lengths of aligned slots that are formed through the first and second arms. The position of the connecting element in the slots, and the configuration and orientation of the slots determine whether the arms are drivingly connected or disconnected. When connected, the arms pivot in the unison when the handle is moved to its operated position to cause the latch operation.

Abstract: A handle operating mechanism that may be lockable includes a housing that defines a forwardly facing recess for receiving a handle that is movable from a nested non-operated position to an extended operated position. A connection plate located behind the housing is pivotally supported by the housing for limited angular movement from a non-operated orientation to an operated orientation in response to movement of the handle from the non-operated position to the operated position. The connection plate is provided with a plurality of connection formations arrayed in a novel way about the pivot axis of the connection plate to ensure that pairs of lengthy, oppositely directed links coupled to the connection formations move concurrently and substantially equidistantly to operate various arrangements of remotely located latches including pairs of latches situated on opposite sides of the handle operating mechanism.

Abstract: A folding foot step of the type used on vehicles has an improved anti-skid, friction grip, stand-on surface with a clover-leaflet-shaped perimeter. The stand-on surface is interrupted by three elongate openings that are spaced inwardly from the perimeter and arrayed to extend about an uninterrupted central region of the stand-on surface. An upwardly-opening recess is defined by a narrow upstanding rim that runs along and defines the perimeter of the stand-on surface, and by narrow upstanding rims that encircle the three openings.

Abstract: A rotary latch employs at least one rotary jaw that is releasably retained in its latched position by a rotary pawl. Housing side plates sandwich the rotary jaw, the rotary pawl and one or more torsion coil springs that bias the rotary jaw from an unlatched position toward a latched position, and the rotary pawl from a jaw-releasing position toward a jaw-retaining position. Improvements that enhance service longevity include the use of C-shaped hook formations defined by reaches of spring material that extend from torsion spring coils located alongside one or both of the rotary jaw and the rotary pawl to engage convexly shaped C-shaped formations of the rotary jaw and/or the rotary pawl that are located in the same plane as the torsion spring coils to provide long-lived connections between the torsion spring or springs and one or both of the rotary jaw and the rotary pawl.

Abstract: Weather resistant push button operator assemblies usable with a variety of latch and lock systems are disclosed that employ O-ring seals along inner and outer diameters of tubular push button operators that may be provided with key operated lock cylinders. A clamp-on bracket and linkage assembly is disclosed that may be used to enable the push button operator assemblies to pivot pairs of latch connected links in opposite directions to concurrently release pairs of remotely located latches.

Abstract: A latch, lock and hinge system having components that are well suited for use with closures such as tonneau covers that close the upwardly opening rear cargo compartments of pickup trucks and the like, includes rotary latch assemblies that are mounted on hinges for releasably engaging latch strikers to provide cover mounting connections that permit the cover both to pivot between open and closed positions, and to be removed when desired. The hinges have pivotally connected arms that are biased to hold the hinge-carried latches adjacent the cover when the cover is removed. Also included are other rotary latch assemblies that are connected by flexible cables to a latch operator assembly having an elongate housing that defines near its opposite ends a pair of recesses wherein latch operators are nested that can be concurrently moved toward each other by the fingers of one hand to unlatch and pivot open the cover. The latch operator assembly is lockable to prevent the cover from being opened and/or removed.
