An apparatus for picking up an object has an elongated handle having a lower end carrying a downwardly open bell. A tubular body inside the bell has a lower edge and can move between a lower position with this edge projecting downward past a lower bell edge and an upper position. A downwardly open bag has a closed upper end releasably retained inside the tubular body and an open end lying against an outer surface of the lower body edge. An elastic annular element engages around the body and the bag immediately above the tapered lower body edge and holds the bag against the outer surface of the lower end of the tubular body. Upward displacement of the tubular body into the upper position causes the lower bell edge to downwardly engage and push the elastic annular element downward off the tubular body.

The invention claimed is: 1. An apparatus for picking up an object on a floor surface, the apparatus comprising: an elongated handle having an upper end and a lower end; a downwardly open bell at the lower handle end and having a lower edge; a tubular body inside the bell and having a downwardly and inwardly tapered lower edge, the body being shiftable inside the bell between a lower position with the lower body edge projecting downward past the lower bell edge and an upper position with the lower body edge above the lower bell edge; means urging the tubular body into the lower position; a downwardly open bag having a closed upper end inside the tubular body and an open end lying against an outer surface of the lower body edge; means for releasably retaining the closed upper bag end in the bell; and an elastic annular element engaged around the body and the bag immediately above the tapered lower body edge and holding the bag against the outer surface of the lower end of the tubular body, the tubular body fitting in the bell such that upward displacement of the tubular body into the upper position causes the lower bell edge to downwardly engage and push the elastic annular element downward off the tubular body so that the elastic annular element contracts elastically and closes the bag, whereby, when the lower body edge is pressed against the floor surface around an object to be picked up, the tubular body moves upward in the bell and the elastic element is pushed by the bell down off the tubular body and closes the bag while simultaneously sweeping the object into and enclosing it in the bag. 2. The apparatus defined in claim 1 wherein the retaining means includes a pair of jaws displaceable between a gripping position holding the closed upper bag end and a freeing position releasing the closed upper bag end. 3. The apparatus defined in claim 2 wherein the handle is tubular, the retaining means further including a rod extending vertically through the handle and having a lower end connected to the jaws for displacing same between the gripping and freeing positions. 4. The apparatus defined in claim 3 wherein the retaining means further includes a spring biasing the jaws into the gripping position. 5. The apparatus defined in claim 4 wherein the retaining means includes portions of the bell bearing against the jaws in the gripping position. 6. The apparatus defined in claim 1 wherein the urging means includes at least one spring between the tubular body and the bell. 7. The apparatus defined in claim 1 wherein the urging means includes a plurality of elongated spring elements extending upward from and bearing upward on the bell. 8. The apparatus defined in claim 1, further comprising a plurality of parallel interfitting guides on the bell and on the tubular body constraining the body for movement in a straight line relative to the bell. 9. The apparatus defined in claim 8 wherein the guides include parallel radially inwardly projecting ridges formed in the bell and parallel radially outwardly open grooves complementary to and receiving the ridges and formed in the tubular body. 10. The apparatus defined in claim 1 wherein the lower edge is substantially planar and perpendicular to a direction of movement of the tubular body in the bell. 11. The apparatus defined in claim 1 wherein the bell has a substantially cylindrical side wall and the tubular body is substantially cylindrical.
