Abstract:
A refuse collection device comprising:an inner tube having upper and lower ends; an outer tube having upper and lower ends, the outer tube being telescopically fit over and axially movable with respect to the inner tube between a lower closed position and an upper dumping position via an intermediate open position; a mount fixed to the lower end of the inner tube and defining a refuse passage for entry of a refuse; a cover rotatably connected to the mount by a pivot pin whereby the cover is movable with respect to the mount for selectively closing the refuse passage; a connection link coupling the cover to the outer tube whereby the cover is rotated with respect to the mount when the outer tube is moved with respect to the inner tube between the upper, open position and the lower, closed position; a control device comprising a first multi-stepped groove defined in an inside surface of the outer tube, at least one hole defined in the inner tube and movably receiving a spherical member therein, the hold being positioned so that the spherical member is allowed to partially enter the first multi-stepped groove of the outer tube, a shank movably and axially received in the inner tube and defining a second multi-stepped groove corresponding in position to the hole of the inner tube whereby the spherical member is allowed to partially enter the second multi-stepped groove, wherein engagement between the spherical member and the first and second multi-stepped grooves allows the outer tube to be selectively retained at the lower, intermediate and upper positions with respect to the inner tube; and a retainer having a cylindrical body fit over the lower end of the outer tube and being secured to the outer tube by at least one finger which is engaged in a corresponding slot on the outer tube, the retainer receiving a portion of the connection link to secure the connection link to the outer tube.
