Abstract

A snow grooming apparatus and system for grooming snow barriers and elements. The apparatus has an inlet to accept the snow, and at least one smoothing member attached to the rear of the inlet. The smoothing members are dimensioned to pass over the snow formed by the inlet and to smooth at least one side of the snow such that the resulting barrier has at least one substantially smooth side. The system includes the snow grooming apparatus attached to a blade of a snow grooming vehicle.

Claims

1. A grooming apparatus for forming a barrier of snow, said apparatus comprising:

an inlet for receiving and forming a quantity of snow, said inlet comprising a front, a rear, a top, a first side and a second side, and being dimensioned to form the quantity of snow into said barrier; and

at least three smoothing members attached to, and extending from, said rear of said inlet, said smoothing members being dimensioned to smooth at least one surface of the barrier;

wherein the quantity of snow is received by said inlet, is formed by said inlet into a barrier, and is smoothed by said smoothing members such that a barrier having at least one substantially smooth surface is formed.

2. The grooming apparatus as claimed in claim 1 wherein said at least one smoothing member is manufactured of a substantially flexible material.

3. The grooming apparatus as claimed in claim 2 further comprising at least one spring for maintaining said at least one smoothing member in contact with said surface of said barrier.

4. The grooming apparatus as claimed in claim 1 wherein said inlet is tapered inward such that said front of said inlet is larger than said rear of said inlet.

5. The grooming apparatus as claimed in claim 4 wherein said front and said rear of said inlet are substantially rectangular in cross section and wherein said inlet further comprises a top, a first side and a second side.

6. The grooming apparatus as claimed in claim 1 further comprising an attachment for attaching said apparatus to a blade of a snow grooming vehicle.

7. The grooming apparatus as claimed in claim 6 wherein said attachment is an attachment for removably attaching said apparatus to said blade.

8. The grooming apparatus as claimed in claim 7 comprising:

three smoothing members attached to, and extending from, said rear of said inlet; and

a plurality of springs for maintaining said smoothing members in contact with said surface of said barrier;

wherein said inlet further comprises a top, a first side and a second side, and is tapered inward such that said front of said inlet is larger than said rear of said inlet.

16. The grooming system as claimed in claim 8 wherein said grooming apparatus is removably attached to said blade.

9. A grooming system for forming barriers of snow, said system comprising:

a blade dimensioned for attachment to a grooming vehicle said blade having a first side and a second side; and

a grooming apparatus attached to one side of said blade, said grooming apparatus comprising;

an inlet for receiving and forming a quantity of snow, said inlet comprising a front and a rear, and being dimensioned to form the quantity of snow into a barrier; and

at least one smoothing member attached to, and extending from, said rear of said inlet, said smoothing member being dimensioned to smooth at least one surface of the barrier;

wherein said blade is attached to the grooming vehicle, is lowered to a desired height and is propelled forward to form a lane and such that a quantity of snow is received by said inlet, is formed by said inlet into a barrier bounding said lane, and is smoothed by said smoothing member such that the barrier has at least one substantially smooth surface.

10. The grooming system as claimed in claim 9, wherein said grooming apparatus comprises at least two smoothing members attached to, and extending from, said rear of said inlet.

11. The grooming system as claimed in claim 10 wherein said inlet of said grooming apparatus further comprises a top, a first side and a second side and wherein said grooming apparatus comprises three smoothing members attached to, and extending from, said rear of said inlet.

12. The grooming system as claimed in claim 9 wherein said at least one smoothing member of said grooming apparatus is manufactured of a substantially flexible material.

13. The grooming system as claimed in claim 12 wherein said grooming apparatus further comprises at least one spring for maintaining said at least one smoothing member in contact with said surface of said barrier.

14. The grooming system as claimed in claim 9 wherein said inlet of said grooming apparatus is tapered inward such that said front of said inlet is larger than said rear of said inlet.

15. The grooming system as claimed in claim 14 wherein said front and said rear of said inlet of said grooming apparatus are substantially rectangular in cross section and wherein said inlet further comprises a top, a first side and a second side.

17. The grooming system as claimed in claim 9 wherein said blade comprises a curved bottom edge.

18. The grooming system as claimed in claim 17 wherein said grooming apparatus comprises:

three smoothing members attached to, and extending from, said rear of said inlet; and

a plurality of springs for maintaining said smoothing members in contact with said surface of said barrier; and

wherein said inlet of said grooming apparatus further comprises a top, a first side and a second side, and is tapered inward such that said front of said inlet is larger than said rear of said inlet.

19. A grooming apparatus for forming a barrier of snow, said apparatus comprising:

an inlet for receiving and forming a quantity of snow, said inlet comprising a front and a rear, and being dimensioned to form the quantity of snow into said barrier; and

at least one smoothing member attached to, and extending from, said rear of said inlet, said smoothing member being manufactured of a substantially flexible material and dimensioned to smooth at least one surface of the barrier; and

at least one spring for maintaining said at least one smoothing member in contact with said surface of said barrier;

wherein the quantity of snow is received by said inlet, is formed by said inlet into a barrier, and is smoothed by said smoothing member such that a barrier having at least one substantially smooth surface is formed.

20. The grooming apparatus as claimed in claim 19 wherein said inlet is tapered inward such that said front of said inlet is larger than said rear of said inlet.
