ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a snow blocker attachment for a device used to move snow for substantially preventing snow from spilling out from one of the sides of the snow moving device.
Skid loaders and front end loaders have buckets which have equal and opposite side walls and which are generally used to pick up and carry objects and which have also been used to move snow on roads, driveways, and parking lots. Snow which is gathered on parking surfaces or on sidewalks or driveways is best moved by pushing the snow to one end thereof. Unfortunately, when a user uses a skid loader, front end loader or even a scoop or shovel, the bucket or shovel has a limited capacity to hold the snow, and as the user pushes the snow with the bucket or scoop, the snow spills around both sides of the bucket or scoop making the process of moving the snow more time consuming because the user has to go over the snow which spilled around the sides. None of the prior art actually solves this problem.
One known prior art is a PLOW WITH ARTICULATING BLADE, U.S. Pat. No. 5,758,728, issued on Jun. 2, 1998 and invented by Edward J. Ragule and comprising a gate member that is hinged to the main blade, a drive means for moving the first gate member, a second gate member mounted to the main blade, and a linking means for moving the second gate member relative to the first gate member.
Another known prior art is a SNOW RETAINING GATE FOR FRONT END DIAGONAL PLOW, U.S. Pat. No. 3,407,519, issued on Oct. 29, 1968 and invented by A. D. Batko and comprising a gate, means for pivotally mounting the gate to the blade, and a power means for moving the gate between an operative position and an inoperative position.
Another known prior art is a SNOW WING GATE, U.S. Pat. No. 4,077,139, issued on Mar. 7, 1978 and invented by Leroy W. Fagervold et al and comprising a frame, bracket means mounted on the frame for securing the frame to the plow blade, a gate member pivotally mounted to the frame, and actuating means for pivoting the gate member.
None of the prior art describes a snow blocking attachment of the present invention.
SUMMARY OF THE INVENTION
The present invention relates to a snow blocker attachment for a device used to move snow comprising a snow blocking means rotatably mounted upon a mounting means which is securely attached to one side of the snow moving device. The snow blocking means includes a wall having a hole therethrough and being removably balanced upon a hub member which is securely attached to a bracket member which is securely fastened to the snow moving device. Another embodiment includes three plate-like members, two of which are securely attached to one side of the snow moving device and the third of which is securely attached along a top of the snow moving device.
One objective of the present invention is to provide a snow blocker attachment for a device used to move snow which substantially reduces the amount of time needed to clear a surface with snow on it.
Another objective of the present invention is to provide a snow blocker attachment for a device used to move snow which can be easily and quickly mounted to the snow moving device without having to attach hoses and other power means as found in the prior art.
Yet, another objective of the present invention is to provide a snow blocker attachment for a device used to move snow which can be effectively used when the snow moving device is moving either forward or backward.
Further objectives and advantages of the present invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawings wherein:
