Abstract: An improved button-type latch to releasably secure a door, having a spring loaded latch bolt retained within a cylindrical housing. The housing further comprises a pair of leaf springs longitudinally directed toward a front of the button latch, the leaf springs cooperating with a retaining lip on the housing to capture a structure surface to maintain the button latch therein.

Abstract: A latch assembly for releasably securing a closure element with a striker element in a closed position. The latch assembly consists of first and second latch elements mounted to a housing for movement relative to each other and the housing, with the first latch element being movable relative to the housing between a latched position and a release position, and cooperating structure on the release lever for moving the second latch element relative to the housing and, in response thereto, causing the first latch element to move from its latched position to its release position. A guard plate is positioned between the housing and the first latch element to more securely retain the striker element and prevent tampering or theft.

Abstract: A toolbox latch is disclosed having a pivoting handle mounted to a housing and mechanically linked to a pusher arm for setting in motion a series of linkages to trap and release a cooperating striker pin. The pusher arm rotates a swiveling trip lever when a turn-key member is first rotated into an unlocked position and the handle pulled in a pivoting motion away from the housing. The swiveling trip lever in turn rotates a rotating link member out of its locking position with a rotating lock lever, allowing a biasing spring on the rotating lock lever to rotate out of its trap position. The cooperating striker pin is thus freed from the trap position as the rotating link member disengages with the rotating lock lever and the latch is open.

Abstract: A security device for a vehicle door or shipping container hasp includes a hinged cover with a window that permits the hasp to partially project thereinthrough, and a lock for fixing the cover in an overlaying relationship with the hasp. The cover includes slots on the side for bypassing a lever held by said hasp, and otherwise shields the hasp from intrusion from a prying tool.

Abstract: The present invention provides a two-way vent for a vehicle that opens in a front and rear direction and includes a preferably symmetric cam having an apex on its centerline, and first and second convex sides each terminating respectively in a recess at the base of the cam. The degree of opening of the vent is determined by the displacement of a follower rod with respect to the apex of the cam. From its originally closed position with the follower positioned at the apex, the vent can be opened either forward or backward by selectively moving a handle that actuates the follower along the curved paths defined by the convex sides. The cam preferably includes a lateral cusp at the end of each curved path, the cusp defining a transition from the curved path to the recess.

Abstract: A locking mechanism having a housing with an aperture having at least one notch and providing access to a latching mechanism for a cylindrical lockset having a barrel section with an outwardly projecting tab which may be inserted through the aperture and to engage the latching mechanism being rotatable to engage the tab with the inner surface of the housing inhibiting removal of the lockset. A set screw mounted on the housing is incorporated to prevent rotation of the lockset by engaging a groove in the barrel section.
