A refuse collection device includes an elongated tubular assembly comprising an inner tube, an intermediate tube and an outer tube telescoping each other and a bag mount supporting thereon a refuse collection bag attached to the lower end of the tubular assembly and closable by means of a pivoting cover. A manual controller is provided, including a first grip fixed to the outer tube and a second grip fixed to the intermediate tube so as to allow the first grip and the outer tube to be movable relative to the second grip and the intermediate tube between an upper open position and a lower closed position. The cover is coupled to the outer tube so as to be driven thereby between the open position and the closed position. Spherical members are received within openings formed on the intermediate tube and spring-biased to selectively engage a recess formed on the outer tube so as to secure the outer tube in the open position. The inner tube is also movable and spring-biased relative to the intermediate tube to expand and thus securely hold the collection bag. A releasing mechanism is provided to move the inner tube relative to the intermediate tube for releasing the bag against the biasing spring. The releasing mechanism also functions to release the outer tube from the open position.

A refuse collecting device includes an elongated tube having an inner cylinder slidably received in the upper portion and a bag mount having a half moon shaped frame with a cylindrical section slidably received within the lower end of the tube in a spring-loaded manner. A bag is releasably mounted to the mount by having one side attached to the mount and an opposite side attached to the tube and being expanded by the spring. A paddle is rotatably mounted to the tube to correspond to the half moon frame and movable relative thereto to cover/discover the frame that expands the bag. A grip in the form of a hollow cylinder fit over the tube is coupled to the inner cylinder so to be manually movable along the tube to move the inner cylinder inside the tube. A transverse positioning pin extends through slots formed on the inner cylinder to be moved thereby. A first wire connects the paddle to the positioning pin and has a first slack. A second wire connects the mount to the positioning pin and has a second slack. The second slack is greater than the first slack so that the open operation of the paddle and the release of the bag can be performed by a single hand moving the inner cylinder via the grip to travel different distance. A two stage positioning control device may be provided to secure the positions of the positioning pin.

A refuse collection device includes an elongated tubular assembly comprising an inner tube, an intermediate tube and an outer tube telescoping each other and a bag mount supporting thereon a refuse collection bag attached to the lower end of the tubular assembly and closable by means of a pivoting cover. A manual control is provided, including a first grip fixed to the outer tube and a second grip fixed to the intermediate tube so as to allow the first grip and the outer tube to be movable relative to the second grip and the intermediate tube between an upper open position and a lower closed position. The cover is coupled to the outer tube so as to be driven thereby between the open position and the closed position. Spherical members are received within openings formed on the intermediate tube and spring-biased to selectively engage a recess formed on the outer tube so as to secure the outer tube in the open position. The inner tube is also movable and spring-biased relative to the intermediate tube to expand and thus securely hold the collection bag. A releasing mechanism is provided to move the inner tube relative to the intermediate tube against the biasing spring for releasing the bag. The releasing mechanism also functions to release the outer tube from the open position.

A refuse collection device includes a tubular portion to which a bag mount is attached. The bag mount defines a passage. A cover is movably mounted to the bag mount for openably closing the passage. A flexible bag, such as a plastic bag, has a front opening fit over and releasably secured to the bag mount for receiving refuses through the passage. The bag is comprised of first and second sheets, each having a front edge folded over sections of the bag mount. The front edge of the first sheet forms a cut line dividing the front edge into two opposite free flaps for facilitating mounting the bag to the bag mount. A flap retainer is mounted to the tubular portion and is biased by a torsional spring to securely fix the flaps to the bag mount thereby preventing the flaps from arbitrarily moving within the passage and thus enhancing collection of refuses into the bag. The torsional spring has a small spring constant that is only sufficient to overcome inherent resiliency of the flaps for effectively retaining the flaps in position while causing no substantial interference with mounting and dismounting of the bag to and from the bag mount. An envelop is fit over the cover for protecting the cover from contamination by the collected refuses. A flexible strip extends from the bag, having a free end attached to the envelop whereby the bag and the envelop can be removed from the bag mount at the same time.

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.
