A refuse collection device includes an outer tube in which an inner tube is
telescopically received. The outer tube is movable with respect to the
inner tube between a lower closed position and an upper dumping position
via an intermediate open position. A mount defining a refuse passage for
the entry of a refuse is mounted to a lower end of the inner tube. A cover
is 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 couples 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, dumping position and the
lower, closed position. A control device includes a first multi-stepped
groove defined in an inside surface of the outer tube, radially extending
holes defined in the inner tube and each movably receiving a spherical
member and a shank movably and axially received in the inner tube and
defining a second multi-stepped groove corresponding in position to the
holes of the inner tube. The holes are positioned so that the spherical
members are allowed to partially enter and engage the first and second
multi-stepped grooves whereby the engagement between the spherical members
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.
