  • Patent number: 9963276
    Abstract: A latch is usable for latching and automatically unlatching a lid operative to close a bin of a waste container. The latch includes a release weight that is moveable responsive to gravity from a first position to a second position to cause the latch to disengage from a release mechanism when the latch is rotated to one or more angular positions in a dump angular orientation. The latch and release mechanism are held in latched engagement when release slide bolts and latch slide bolts are engaged in extended positions. Movement of the release weight causes the latch slide bolts to move to retracted positions to enable disengagement of the release slide bolts and latch slide bolts. A release knob is operative responsive to manual movement in two different directions to enable the latch and release slide bolts to disengage.

When the operation handle is operated in a swing manner, a front end portion of each slide pin is retracted from each lock hole of the support member against pressure of each spring. Engagement holes are defined on opposed surfaces of each front end portion of the cam member having a cylindrical shape. Each rear end portion of the slide pin is formed in a bifurcated structure to have elastic pieces. Each of elastic pieces has a protrusion for detachably engaging with each of engagement holes.

  • Patent number: 7455333
    Abstract: A side lock apparatus comprises a retainer, a rotor rotatably supported on the retainer, a pair of rods which are brought into engagement with positions which are point symmetrical relative to an axial center of the rotor at proximal end portions thereof and are supported in such a manner that distal end portions thereof appear from and disappear into both ends of a lid so as to be brought into engagement with and disengagement from a circumferential edge of an opening, a knob supported on the retainer in such a manner as to be pushed and pulled on and a return spring mounted on the rotor. When the knob is pulled on, since a pusher element of the knob pushes on a bearing portion of the rotor, the rotor rotates against the biasing force of the return spring, whereby the rods are withdrawn into the inside of the lid.

  • Patent number: 7445254
    Abstract: A latch apparatus includes a live bolt actuated between an extended position and a retracted position, first and second dead bolts, and a slide. The first dead bolt is positioned vertically above the live bolt and the second dead bolt is positioned vertically below the live bolt. The first and second dead bolts have substantially the same size and shape and are spaced equidistant from the live bolt. The slide couples the first and second dead bolts to each other, wherein vertical movement of the slide simultaneously actuates the first and second dead bolts between extended and retracted positions.
