The locking means moves to a second disposition in which the catch and the aperture cooperate together so that the locking means rides upon the plate. The locking device moves to a third disposition in which the catch is latchingly disposed within the aperture for securing the closure member to the frame. A backing plate is rigidly secured to the locking device for pivotal movement therewith. The arrangement is such that the closure member is disposed between the backing plate and the locking device.

Abstract: A latch member of a case or similar container blow-molded from thermoplastic material is pivotally and permanently secured to the case by a bearing formed substantially simultaneously with and from the same thermoplastic material as the body of the case. Formation of a permanent bond between the bearing member and the latch member is avoided by employing a latch member formed of material having a higher melt temperature than the material used in the formation of the main body of the case and the bearing member, and also by effecting relative movement between the latch member and the bearing member while the thermoplastic material forming the bearing member is still in a heated condition. Apparatuses for positioning the latch member within the mold are also disclosed.

Abstract: The rear horizontal gate or tailgate of a truck is locked in a vertical or horizontal position by a pivoting horizontal bar. Fingers extend fixedly outward from the rear of the bed of a truck. The bar hinges are slit so that in the horizontal position they swing down over and grasp the fingers, holding the tailgate in a locked downward position. The tailgate is placed into an upward position by swinging the bar outward, freeing it from the fingers and raising the gate vertically. The weight of the horizontal bar swings down and the bar latches against the upper surface of the support fingers, holding the tailgate in a locked upward position. The tailgate thus can be locked in one of the two positions, up or down, while the truck is in motion without requiring the use of lock pins, simply by manipulation of the weighted horizontal bar and hinge member.

Abstract: The invention is directed to an automatic locking mechanism for a dumpster container having a hinged lid. The elements of the locking mechanism comprise an L-shaped or U-shaped securing member which is attached to one or both sidewalls of the container. The securing member pivots over the lid, and is held in place by a securing mechanism. The securing mechanism fixes the L-shaped or U-shaped securing member in a position that inhibits opening of the container lid. The securing mechanism is autonatically operated by the lifting tines of a trash removal vehicle. The L-shaped or U-shaped locking member automatically swings away from the hinged lid by virtue of a counterweight during container dumping operations, and is returned to a locked configuration when the container is replaced and the lifting tines withdrawn.

Abstract: A permanent locking device for a nuclear waste container which, in combination with a lid and a box, utilizes a dee-shaped ring held by a wide, flat hinge and a protruding narrow malleable metal retaining strap. The ring can rotate or slide up and down within the hinge, as well as slide side to side. The hinge has a slot in its top for temporarily holding the ring in an up position while the lid is open and the box is being loaded with nuclear waste. When the lid is closed and the ring is disengaged from the slot, the ring can be quickly dropped to a down position permitting the retaining strap to extend through the ring. The retaining strap can then be readily bent down and over the circular (bottom) portion of the ring, to form a permanent seal. A deformable rubber gasket is positioned between the lid and the top edges of the box to form an air tight seal.
