  • Patent number: 5042856
    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dumping operations, and is returned to a locked configuration when the container is replaced and the lifting tines withdrawn.

  • Patent number: 4429911
    Abstract: A security bar system for physically preventing unwanted opening of a door. The system preferably comprises an elongated, rigid, generally cylindrical bar which is adapted to extend in front of the door between a pair of mounting brackets. The door bar terminates at its opposite ends in flange members which are separated from the major length of the bar by reduced diameter segments of predetermined length. The door bar is adapted to axially penetrate, and be restrained by and between, the bracket members. Each bracket member includes a symmetrical slot geometry whereby to permit mounting of the system in either a right or left sided application. A first mounting bracket includes an elongated slot, the center of which is provided with a clearance hole to axially receive one bar flange. The reduced diameter segment of the door bar tracks within the extremities of the slot.

  • Patent number: 4429908
    Abstract: By providing a single biasing element (spring) connected through pull rods to toggle means in laterally-inverted relationship, there are overcome the problems of (1) inequality of forces on the latching beams and (2) the need for relatively massive springs. The toggle means provide a force-multiplying effect. Moreover, no special actuating element is required for latching or unlatching.

  • Patent number: 4418551
    Abstract: The cash box of a vending machine is protected by a heavy steel door or pair of doors which are locked across the front of the juke box covering the cash box, the door or doors being mounted on a framework consisting of steel straps which wrap around the back, and preferably the top and bottom as well, of the vending machine and interlock in such a way that they can be installed without screws, bolts or other fastening structure and will positively be locked into place when the barrier door or doors are closed. This configuration eliminates the need to mount a barrier door onto the vending machine, which is somewhat time consuming and tricky due to the strength of the mounting that is required.

  • Patent number: 4365832
    Abstract: In accordance with the present invention a hatch cover hold down arrangement is provided including a handle which pivots about a first mounting pin. The handle includes an elongated locking slot. A locking member includes an extension which in one position is located over and holds in place a hatch cover. A locking pin extends from the locking member into the elongated slot in the handle and a mounting pin slot is provided in the locking member which receives the mounting pin upon which the handle is pivotably mounted. Preferably the mounting pin is supported by a flange located adjacent to the locking member which includes a vertical surface which guides the locking member during vertical movement between open and closed positions. The locking member includes a surface which engages the flange vertical surface as the locking member is lifted by the handle and locking pin from the closed position toward open position and prevents initial rotation of the locking member.
