Abstract

Snow rake having a generally rectangular main body formed of a closed-cell, resilient, low-density polyethylene bead, which main body is clamped between two spaced, parallel plates to one of which a handle is attached.

Claims

1. A snow rake comprising:

(a) an elongated generally rectangular single, integral main body of resilient low density foamed thermoplastic material, said main body having a broad front surface and broad back surface, and at least one narrow scraping edge, said front surface having a shallow front recess, said back surface having a shallow back recess,

(b) a rigid flat front plate of high density solid thermoplastic material which lies in said front recess,

(c) a rigid flat back plate of high density solid thermoplastic material which lies in said back recess,

(d) an elongated handle which is removably attached to said back plate so that the handle extends substantially at a right angle to said back surface, and

(e) connecting means for fixing said front plate to said back plate so that said main body is clamped between said front and back plates.

2. A snow rake as recited in claim 1, wherein the thermoplastic material of said main body is polyethylene.

3. A snow rake as recited in claim 1, wherein said main body has a central bore which extends at a right angle to said front and back surfaces, said back plate has a tubular projection which extends into said bore, said tubular projection has internal threads and a rearwardly facing opening and, wherein one end of said handle has external threads for screwing into said tubular projection.

4. A snow rake as recited in claim 1, wherein said main body has at least one aperture which extends from said front plate to said back plate, wherein one of said plates has at least one projection which extends to the other of said plates and, wherein said projection is connected to the other of said plates by fastening means.

5. A snow rake as recited in claim 4, wherein said projection is a primary projection and the other of said plates has a tubular projection which receives said primary projection in a telescoping fit.

6. A snow rake comprising:

(a) an elongated generally rectangular single integral main body of relatively soft thermoplastic material, said main body having a broad front surface and a broad back surface, at least one narrow scraping edge, a central aperture and at least one secondary aperture,

(b) a flat front plate of relatively hard thermoplastic material which lies against said broad front surface, said front plate having a central projection which extends into said central aperture and a secondary projection which extends rearwardly into said secondary aperture, said central projection has a threaded bore and a front opening to the bore,

(c) a flat rear plate of relatively hard thermoplastic material which lies against said back surface, said back plate having at least one secondary projection which extends forwardly into said secondary aperture for engaging the secondary projection of said front plate, and

(d) fastening means for fixing the secondary projection of said back plate to the secondary projection of said front plate so that said main body is clamped between said front and back plates.

7. A snow rake as recited in claim 6, wherein one of said secondary projections has a bore and an opening to the bore and the other of said secondary projections extends into the bore of said one projection in a telescoping fit.

8. A snow rake as recited in claim 7, wherein said fastening means is a screw which extends freely through one of said secondary projections and is threaded into the other of said secondary projections.
