ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to an animal waste removal apparatus. More specifically, the invention is a pet litter removal device which enables the user to scoop up pet litter into an attached bag without the strain of bending over in the process.
2. Description of Related Art
The related art of interest describes various pet litter devices, but none discloses the present invention. There is a need for an economical lightweight litter pickup device in this crowded art which is simple in construction with a scooping trapdoor. The related art will be discussed in the order of perceived relevance to the present invention.
U.S. Pat. No. 6,196,600 B1 issued on Mar. 6, 2001, to Brooke D. Miller describes an animal waste scooping and disposal device comprising a plastic telescoping inner pole attached to an aluminum tray having extended forks in front and a triangular shaped waste exiting opening in the rear. The rear end of the tray can be modified with a peripheral groove for attaching a bag. The outer pole has a handle at the upper end, a tray release button and a two-prong female clip-on device to hang a portable rake. Two holding arms from the outer tube support the tray and allow the tray to automatically pivot when waste is added. The device is distinguishable for its required pivoting tray with extended fork elements.
U.S. Pat. No. 5,820,179 issued on Oct. 13, 1998, to Eric Tsou describes a refuse collection device comprising three concentric tubes telescoping each other. The handle consists of a first grip fixed to the outer tube and a second grip fixed to the intermediate tube. This structural arrangement allows the first grip and the outer tube to be movable relative to the second grip and the intermediate tube. A semicircular shaped (in cross-section) bag mount supporting a refuse collection bag is mounted at the opposite end of the tubes. The semicircular shaped cover is coupled to the outer tube for opening and closing the cover. Spherical members are received within openings in the intermediate tube and spring-biased to engage a recess formed on the outer tube to secure the open cover position. The inner tube is also spring-biased to expand to hold the collection bag. A releasing mechanism moves the inner tube relative to the intermediate tube to release the bag against the biasing spring and to release the outer tube from the open position. The device is distinguishable for its unique multiple tubular shaft structure.
U.S. Pat. No. 6,113,166 issued on Sep. 5, 2000, to David S. Wynn describes a sanitary pickup apparatus for animal feces comprising an open frame assembly vertically supporting a telescoping handle. When the handle is pushed down, a panel sweep assembly is vertically pivoted about a horizontal axis to propel the feces into the open end of a removable receptacle. The apparatus is distinguishable for its unique telescoping handle and open frame structure.
U.S. Pat. No. 5,350,208 issued on Sep. 27, 1994, to Dante C. Heinrichson describes an animal waste pickup and disposal unit comprising a pair of opposed jaws having a plastic bag removably disposed within and attached to a scissors mechanism actuated by an actuator element on the handle. The apparatus is distinguishable for it clamping jaw structure.
U.S. Pat. No. 5,380,054 issued on Jan. 10, 1995, to Misael Galvis describes a handheld device for picking up objects comprising a handgrip assembly, an elongated tubular shaft, a combination plunger and double bell-crank assembly, and clamshell buckets or gripping jaws. The device is distinguishable for its unique clamshell bucket or gripping jaw element.
U.S. Pat. No. 5,895,082 issued on Apr. 20, 1999, to William Kaluzny describes a manual pick-up device comprising a pair of pick-up blades attached to a bent shaft having a handle grip. The device is distinguishable for its pick-up bladed structure.
U.S. Pat. No. 6,030,011 issued on Feb. 29, 2000, to Charles E. Layton describes a waste collection device comprising an elongated handle having a rake device clipped to it for sweeping waste into a waste receptacle frame at the end of the handle for attaching a liner over the waste receptacle frame. The device is distinguishable for its required rake and its waste receptacle frame.
U.S. Pat. No. 6,062,168 issued on May 16, 2000, to Douglas R. Host et al. describes a sanitary refuse and animal dung collection valet device comprising a pair of tubes pivotally connected in a scissors arrangement. The user scoops the waste into a refuse collection bag which is supported at the lower end of one tube on a support frame. A pusher paddle connected to the lower end of the other tube scrapes the waste into the bag. The device is distinguishable for its scissors arrangement and requiring a pusher paddle.
U.S. Pat. No. 6,068,311 issued on May 30, 2000, to Galen K. Jones describes a sanitary pickup device comprising a pair of wire bails on one end of a tubular shaft and a handle shaped either as a bend or a pistol grip. A stationary wire bail and a movable wire bail are fixed to a yoke member. The device picks up the animal dropping by the wire bails to drop into an open bag. The device is distinguishable for its open bail structure.
U.S. Design Pat. No. 369,444 issued on Apr. 30, 1996, to Monte Ubdegrove et al. describes an animal feces retriever device comprising a clamping tray with two jaws with one lower jaw fixed to the end of a cylindrical rod and the upper jaw raised by a cable to the pistol grip handle. The device is distinguishable for its clamping jaws.
U.S. Pat. No. 4,986,587 issued on Jan. 22, 1991, to Amaro Lozano describes an animal waste collecting device comprising a two-piece post having a perpendicular handle at the top and a rod frame supporting a scoop with a normally extending edge portion with a curved upper edge. A paper or polyethylene bag is attached to the ends of the rod frame and to an L-shaped hook on the lower post. The device is distinguishable for its flat tray structure with the three-point attachment for the bag.
U.S. Pat. No. 4,958,871 issued on Sep. 25, 1990, to James W. Hemans describes a hand tool for picking up animal droppings comprising a telescopic handle with a belt clip and a spring loaded locking and release button attached to a scooping device. The scooping element comprises a pair of support arms and a centered hook with a tapered blade to form a substantially rectangular opening for a fold-lock-up sandwich bag. The hand tool is distinguishable for its limited height requiring bending over and the use of special sandwich bags.
U.S. Pat. No. 4,962,956 issued on Oct. 16, 1990, to Robert D. Scripter describes an animal waste collection device comprising a straight tubular handle having a retention slot for holding a plastic bag retained on a triangular spring wire frame. The device is pulled towards the user. The device is distinguishable for its triangular wire frame structure and the lack of a closure element.
U.K. Patent Application No. 632,621 published on Nov. 28, 1949, for Laurence Jenks describes reachers or long arm devices comprising a curved hollow arm having a head with movable jaws actuated by a chain on a squeezable hand grip. The hand grip consists of a fixed handle and a movable handle joined by a toggle lever pivoting on a pin on the movable handle and moving on a roller inside the U-shaped fixed handle. The chain is attached to the toggle lever with an adjusting nut. The device is distinguishable for its required movable jaws and toggle lever mechanism.
French Patent Application No. 2 608 651 published on Jun. 24, 1988, for Regine Lemaux et al. describes a dog feces cleaning device comprising a scraper blade attached to a rod by a pincer element. The device is distinguishable for its scraper structure.
W.I.P.O. Patent Application No. WO 94/09212 published on Apr. 28, 1994, for Luis A. Duran Moya describes a bag for collecting refuse material comprising a triangular frame for attaching a plastic bag and scraping up the animal excrement. The device is d
