  • Patent number: 4632201
    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.

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.

  • Patent number: 4407535
    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.

  • Patent number: 4387740
    Abstract: A flange closure formed of a flange body having a cylindrical opening therethrough and having in the opening a concentric internal groove, a cylindrical closure plate for removably closing the opening in the flange body, the closure plate being removable and sealably positionable in the flange opening, a pair of cam plates each hingedly affixed to the closure plate, each of the cam plates having a peripheral edge portion configured as a segment of a circle substantially equal to the diameter of the flange internal groove, and a cam plate actuator removably attachable to said closure plate, the cam plate actuator engaging said cam plates, the actuator is rotated in one direction to forceably retract the cam plates so that the segmented circular edges are within the diameter of the closure plate and when the actuator is rotated in the other direction to extend the cam plates so that the semi-circular edges extend within the flange groove to retain the closure plate in position within the flange opening.

  • Patent number: 4312527
    Abstract: Locking mechanism having a casing including a pair of spaced support plates of similar or identical size and shape. The support plates have identical, spaced, congruent, T-shaped tongues along their front edges. When the locking mechanism is installed in a door, the tongues extend beyond the front edge to engage a C-shaped strike in the door jamb. A pair of flat-bodied, blade-like bolt members, having shank and latch portions at opposite ends, and pivoted therebetween, are located side by side in coplanar relation in a space between the support plates. The latch portions project outwardly beyond the front edge of the door, between the T-shaped tongues. A flat, eccentric, plate-like cam member is rotatably supported between the shank portions of the bolt members. The cam and bolt members are constrained to a mutually coplanar relation by a sliding contact with the inner surfaces of the support plates on both sides.

  • Patent number: 4289342
    Abstract: A motor vehicle door lock comprises a ratchet locking mechanism, behind the preferably bolt-shaped catch of which there can engage the flanks of two locking teeth which are arranged one behind the other and which are arranged on a pivotable locking lever which is pressed into the locking position by spring pressure and which, upon a movement of the catch relative to the lever during the locking of the door, can be pivoted by the catch against the spring pressure. For the opening of the lock there engages in the locking lever (9) or is secured thereto, a driving member (28), by means of which the locking lever can be removed from the catch (2) to such an extent that the respective abutting tooth edge becomes disengaged.

  • Patent number: 4115020
    Abstract: A clamp particularly but not exclusively suited for attaching clip-on units to cargo containers wherein the clamp takes the form of a pivotal arm or arms receivable in a slot or opening which upon subsequent pivotal movement locks the arm or arms in the opening. A preferred mode of pivoting the arm(s) is by way of a camming surface in sliding contact with the arm(s).

  • Patent number: 3943571
    Abstract: A diving helmet including a uniquely designed three element structure and associated connecting and releasing means for quick bail-out, when, for example, the helmet's umbilical cord is damaged, tangled, or cut, to permit quick release and removal of the outer hard hat helmet. The system includes an inner dry hood with a facial opening framed with an oval, tongue-in-groove type seal along with a separate rigid protective outer helmet made up of a hat portion or hard casque and a mask portion with goggles, the two helmet portions being hingedly connected together (note FIG. 2). The hood seal is adapted to match and mate with the goggle mask assembly (note FIG. 3) sustaining the umbilical lines, gas regulators, window etc. to form a dry enclosure therebetween.
