Sanitary waste pickup device
First Claim
Patent Images
1. A sanitary waste pickup device comprising:
- a receptacle cup with a depth, a bottom, an interior surface, a lip, and at least one detente on the interior surface at a first distance below the lip;
a fixed plate with embedded parallel spikes projecting therefrom, the spikes having a length slightly greater than the first distance;
a shuttle plate dimensioned and configured to moveably accept the spikes through a plurality of apertures, each spike passing through an aperture of the shuttle plate, the shuttle plate dimensioned and configured so it may pass the detente on the cup if a first force is applied to the shuttle plate, and may not pass the detente if a second lesser force is applied;
a void at the center of the fixed plate, a solid tube passing therethrough, the solid tube having a first end attached to the shuttle plate and a second end having a first handle attached thereto, the solid tube having a first stop;
a hollow tube attached to the fixed plate and surrounding the solid tube slidably, and having at least first and second catches and at least two springs, disposed within the hollow tube, allowing tension and release against the first catch during relative movement of the solid tub within the hollow tube stops;
the first handle, forming a physical unity whereby the solid tube, and shuttle plate urging the solid tube downwards sets in motion the shuttle plate to scrape clean the spikes as the shuttle plate moves downwards;
a second handle attached to the hollow tube.

Abstract
A two part waste pickup device in which a pick up tool cooperates with a sanitary container to allow one handed pickup and containment of pet wastes. An interior tube inside a hollow tube have disengaging springs with stops inside the hollow tube and on the solid tube to push a shuttle plate over spikes on a fixed plate attached to the hollow tube; the spikes may impale animal waste to be collected and placed in a plastic-bag-lined receptacle cup (the sanitary container), a seal on the upper lip confines materials and odors. The shuttle plate engages detents located on the interior of the receptacle cup. The spring urges the shuttle plate upwards against the detents and the bottom of the fixed plate downwards against the lip of the cup, resulting in the cup and hand tool portion being clamped together.
