  • Patent number: 5593190
    Abstract: The Consistent-Force Quick Latching System (CQLS) provides a means for athing and detaching two objects quickly, using consistent force regardless of the dimensions of the individual objects. The CQLS, usually secured to object A, utilizes a notched cam and a detent that enters one of the notches in response to externally applied pressure and rotates the cam in conjunction with the rotation of a handle that is pivotally coupled to the cam. When the handle rotates in one direction, the cam rotates so as to raise the hook that is also pivotally coupled to the cam, thereby forcing against object A object B that has been slid onto the hook. The two objects are separated from each other by a release mechanism that pulls the detent out of a notch, allowing the handle to rotate in the opposite direction. This lowers the pivot point and thus the hook, resulting in separation of object B from object A.

  • Patent number: 5590921
    Abstract: A latch assembly is mounted in an aperture formed in a first member for releasably retaining the first member against a corresponding second member and in a latched position. The latch assembly includes a handle which is adapted for pivotal rotation. A shaft is included which is connected with the handle. The handle is adapted to facilitate axial movement of the shaft as the handle is pivotally rotated between open and closed positions. A latch is provided on the shaft which is adapted for axial movement corresponding with movement of the shaft. The latch is adapted to releasably retain the second member in engagement with the first member when the handle is in its closed position. A retaining member is also included in connection with the shaft which is adapted for securing the latch in its mounted position on the shaft.

  • Patent number: 5488808
    Abstract: An interlock system for locking wall panel frames. Vertical frame members are provided with keyhole-shaped openings for receipt therethrough of the head of a carriage bolt in one portion and having and a second elongate slotted portion capable of a non-rotationable engagement with the carriage bolt. A threaded shaft of the carriage bolt being threadably engageable by a dowel freely rotationally held by a lever bracket whereby the dowel can be threaded along the threaded shaft to bring the lever bracket against one of the vertical frame members. The latch bracket having camming edges and being pivotal around said dowel in a past-center relation whereby to cam said camming edges against the second frame member and lock the two vertical frame members together without the use of hand tools. Access from only one side of a panel frame joint is necessary to engage or disengage the interlock system.

  • Patent number: 5476020
    Abstract: Apparatus adapted for adjusting the position of articles held together by tensioned fasteners such as bolts having a head, a threaded shaft and a nut into which the shaft is threaded includes first and second washer members that are receivable in a stacked array on the bolt shaft between the bolt head and an adjacent surface of one of the articles. Each of the washer members has a diametrically extending semi-cylindrical groove in the surface thereof which faces the other washer member. A cam lever has opposed cam pins of arcuate non-circular cross-section receivable between the washer members within the grooves. Movement of the cam lever to first or second positions thereof will cam the washer members away from or towards each other respectively, thereby applying tension to or releasing tension from the bolt so as to clamp the articles together or release them for movement relative to each other.

  • Patent number: 5269573
    Abstract: A device for restricting the opening motion of a door comprises a housing (4) for securing to the door and having an opening (6) facing the floor over which the door moves when it is opened and closed. A pivotally movable cam member (5)(5') is mounted within the housing so that it can pivot between an operating position in which it extends through the opening to engage with the floor and prevent opening movement of the door and a retracted position in which it is spaced from the floor. Levers (18,21) (18',21') are provided for moving the cam member between its operating and retracted positions.

  • Patent number: 5201556
    Abstract: Disclosed is a locking mechanism to retain and seal a blast door of an amition compartment against a compartment door frame after an explosion in the compartment. The mechanism has a linkage connected to a panel that is blown off the compartment by the explosion, whereby the panel actuates the mechanism. The linkage turns a cam a controlled amount so that the cam contacts the door in an optimal position for retaining and sealing the door.

  • Patent number: 5173002
    Abstract: A workpiece holder apparatus for either panels or cabinets is disclosed. The holder can be used for either panels or the like or cabinets and assists workers in holding the workpiece, raising the workpiece, and precisely positioning the workpiece into place, thereby facilitating the permanent affixing of the workpiece to the ceiling joist or wall studs and in the case of cabinets installation, against the wall itself. Thereafter, the workpiece holder apparatus can be quickly disassembled after the attachment of the workpiece to the ceiling joist or wall studs.
