Description
2 ~2~'f31 Ihis invention relates to a windshield ice scraper.
In general, ice and snow are manually removed from the windshields of automotive vehicles, using a somewhat primitive ~orm of scraper device. The usual scraper includes an elongated handle with a brush on one end and a hard plastic blade on the other end thereof. When the windshield is coated with ice, the physical effort required to remove the ice is often considerable.
A review of the patent literature fails to yield a solution to the problem. However, there are patents relating to electrically operated devices of generally the type proposed herein, including Canadian Patent No. 643,778, issued to J. Bartos et al on June 26, 1962, and U.S. Patents Nos.

3,613,147, issued to J.H. NorEleet on October 19, 1971 and 4,833,746, issued to C.S. Yong on May 30, 1989. For the most part the patented devices are somewhat complicated or ill adapted to use with an automotive vehicle.
An object of the present invention is to offer a solution to the problem of removing ice and snow fro~ a windshield in the form of a relatively simple, electrically operated device, which can be energized using a car battery.
Another object of the invention is to provide a windshield cleaning device, which is readily portable and particularly adapted for use with an automotive vehicle.
29~7,~
Accordingly, the present lnvention relates to a scraper device for removing snow and ice from the windshield of an automotive vehicle comprising elongated casing means;
handle means at one end of said casing means facilitating manual manipulation of the device; motor means in the other end of said casing means; disc means extending out of said other end of said casing means and connected to said motor means for rotation thereby; bristle means on said disc means for removing snow and ice from a windshield when the disc is rotated; and radially extending blade means on an outer circular surface of said disc means for scraping ice from the windshield during rotation of said disc means.
The invention will be described in greater detail with reference to the accompanying drawings t which illustrate a preferred embodiment of the invention, and wherein:
Fig. 1 is an isometric view of a windshield scraper device in accordance with the present invention;
E`ig. 2 is an exploded, longitudinal sectional view of the scraper device of Fig. l;
Fig. 3 is an exploded, partly sectioned isometric view of one end of the casing oE the device of Fig. 1 and 2;
Fig. 4 is an isometric view of a motor used in the device of Fig. 1 and 2;
Fig. 5 is a partly sectioned isometric view of a disc used in the device of Figs. 1 and 2;
Fig. 6 is a partly sectioned, isometric view from below of the disc of Fig. 5;
Fig. 7 is a plan view of the disc of Figs. 5 and 6;
and Fig. 8 is a bottom view of the disc of Figs. 5 to 7.
Wi-th reference to the drawings, the scraper device of the present invention includes a casing generally indicated at 1, which is defined by an elongated, cylindrical, tubular handle 2 with a closed outer free end 3, a cylindrical motor housing 5 integral with the handle 2 and a cowl 6 integral with the motor housing 5. The handle 2 extends out of one side of the motor housing 5, and is inclined slightly with respect to the cowl 6. A switch 8 is mounted in the top of the handle 2 near the outer end 3 thereof. The switch 8 is connected to a conventional plug 9 for insertion into the cigarette lighter (not shown) of the vehicle by a two wire electrical cord 10 which extends into the handle 2 through a grommet in the outer free end 3 thereof. One wire 13 of the cord 10 is connected to one pole of the switch 8, and the other wire 1~ extends through the handle 2 to one terminal 16 of a motor 18 in the housing 5. A
third electrical wire ].9 extends from the other pole of the switch 8 to a second terminal 20 on the motor 18. Of course, by using a transformer (not shown) the motor 14 could be operated using household electrical current.
2,.6.`3t~
The open top end 22 (Figs. 2 and 3) of the motor housing 5 is externa~ly threaded for receiving an internally threaded, generally frusto-conical cover 23. The shaft 2S oE
the motor 18 extends downwardly through a hole 26 (Fig. 3) in the otherwise closed bottom end 27 of the motor housing 5.
A cylindrical gear 29 is mounted on the bottom end oE the shaft 25 for engaging the longitudinally grooved interior of the hub 30 of a rotor disc 31. The disc 31 is housed more or less completely in the frusto-conical cowl 6.
For such purpose, the cowl 6 includes an annular top wall 33 and an outwardly and downwardly flaring side wall 34 (Figs. 1 to 3).
The disc 31 is defined by a generally bowl shaped body with a circular outer, bottom end 36 and an annular side wall 37. The top end of the side wall 37 is thicker than the bottom end thereof to define an annular shoulder or overhang 38. The side 40 of the shoulder flares outwardly and downwardly from the flat top edge o:E the side wall 37. Three reinforcing ribs 43 extend radially outwardly from the hub 30 to the side wall 37. A plurality of bristles 44 extend downwardly and outwardly from the shoulder 38.
Three radially extending, metal blades 46 are mounted on the bottom surface of the disc 31. The blades 46 are mounted on the leading edge (in the direction of rotation) of generally triangular ramps 47 integral with the bottom wall 36 of the disc 31. As best shown in Figs. 5 and 6, the blades ~2 ~ ,9J ~ 5;~~
46 extend upwardly into the ribs 43 to strengthen the structure. The blades 46 extend downwardly approximately the same distance as the bristles g~.
In ope~ation, the rotating blades 46 serve to brea~
any ice on the windshield of a vehicle, and the bristles ~4 (also rotating) push a throw the ice away Erom the windshield.
By placing most of the weight, i.e. the motor 18 and the disc 31, in one end of the casing l, once the device is placed against an inclined windshield, manipulating of the device is relatively easy.
Thus, there has been described a relatively simple, easy to handle device for removing ice and snow from the windshield of an automotive vehicle.
