Abstract

A device for picking up scattered leaves on a lawn by piercing them with an array of sharp tines extending from a support plate that is held by an extended handle so the user can press the tines into leaves from a standing position. A resiliently mounted discharge plate is carried below the support plates (upper and lower) with the tines extending through respective orifices in the discharge plate. A lever associated with the handle may be actuated to move the discharge plate downwardly and remove leaves from the tines.

Claims3

Dependent claims

A leaf pickup and discharge device comprising:

a) a support plate comprising upper and lower plates each having upper and lower surfaces and a plurality of passageways formed therein extending from said upper to lower surfaces, said upper plate having a collar attached thereto in a central area of the upper surface of the upper plate;
b) a plurality of leaf pickup tines extending downwardly from and perpendicularly to the lower surface of said plate;
c) a support shaft extending upwardly from said collar in the central area of the upper surface of said plate, said shaft being the handle for said device;
d) a discharge plate positioned below said lower plate, said discharge plate having upper and lower surfaces, and a plurality of orifices formed therein in a pattern corresponding to that of said tines, said orifices extending through said discharge plate from the upper to the lower surfaces thereof, the walls of said orifices being perpendicular to said upper and lower surfaces and being adapted to allow a corresponding tine to pass freely therethrough;
e) discharge plate support legs attached to the upper surface of said discharge plate, said legs extending through said passageways in said plate, said legs being disposed to move freely within said passageway;
f) a sleeve slidably disposed around said shaft, said support legs being attached to said sleeve;
g) a coil spring around said shaft positioned between said sleeve and said upper surface of the plate, said spring being compressed when said sleeve moves downwardly;
h) a discharge lever carried at one end by a first pivot, said first pivot journal being fixedly mounted with respect to said sleeve and discharge plate, the other end of said lever being provided with a handle grip, and a second pivot located between said two ends of said lever;
i) a connecting rod carried at one end in said second pivot and rotatably attached to said support plate at the other end whereby when the handle and lever are rotated upwardly said sleeve moves downwardly and said spring is compressed, said support members forcing the discharge plate downwardly for substantially the length of the tines that are disposed in the discharge plate's passageways, and leaves or debris collected on said tines will be removed therefrom by the movement of the discharge plate.
