Abstract

The present invention is a rolling device for cutting sheet material including a planar body member supported vertically on wheeled axles oriented perpendicularly to the vertical planar body member. The planar body member includes a cutting notch and a contained cutting blade member with a cutting edge exposed within the cutting notch. A handle member is secured to the planar body member and extends upwardly opposite the wheeled axles. A crossbar can be attached to the handle member. A user grasps the handle member, or crossbar, and rolls the planar body member forward on the wheeled axles to cut a sheet of material passing into the cutting notch.

Claims

1. A mobile device for cutting sheet material comprising;

(c) said planar body member including a contained cutting blade member with cutting edge exposed within said cutting notch closed end; and

(d) a handle means secured to, and coplanar with, said planar body member, said handle means extending upwardly opposite said rolling support means, said handle means and planar body member forming a grasping notch there between, whereby a user grasps the handle means and rolls the planar body member forward on the rolling support means to cut a sheet of material passing into said cutting notch.

2. The mobile device for cutting sheet material according to claim 1 wherein said rolling support means comprises a front wheeled axle and a rear wheeled axle, said axles positioned in a plane and oriented perpendicularly to said vertical planar body member.

3. The mobile device for cutting sheet material according to claim 2 further comprising a third wheeled axle secured perpendicularly to said planar base member adjacent said front wheeled axle and coplanar therewith.

4. The mobile device for cutting sheet material according to claim 1 wherein said handle means defines an aperture for receiving a crosspiece member.

5. The mobile device for cutting sheet material according to claim 1 further comprising a linear crossbar member positioned perpendicularly to said planar body member in an aperture in said handle means.

6. The mobile device for cutting sheet material according to claim 5 wherein, said handle means aperture and linear crossbar member are positioned near an end of said handle means opposite said rolling support means.

7. The mobile device for cutting sheet material according to claim 5 wherein, said linear crossbar member is removeably positioned in said aperture in said handle means.

8. The mobile device for cutting sheet material according to claim 1 wherein, said contained cutting blade member is removable from said planar body member.

9. The mobile device for cutting sheet material according to claim 2 wherein, said cutting notch is essentially parallel to said plane of said wheeled axles.

10. The mobile device for cutting sheet material according to claim 1 wherein, said contained cutting blade member is positioned on a centerline of said planar body member.

11. A wheeled device for cutting sheet material comprising;

(a) a planar body member supported vertically on a front wheeled axle and a rear wheeled axle, said axles positioned in a plane and oriented perpendicular to said vertical planar body member;

(b) said planar body member including a cutting notch with open and closed ends, said notch positioned adjacent and above said front wheeled axle with open end forward thereof;

(c) said planar body member including a contained cutting blade member with cutting edge exposed within said cutting notch closed end; and

(d) a bulbous handle member secured to, and coplanar with, said planar body member, said handle member extending upwardly opposite said rear wheeled axle, said handle member and planar body member forming a grasping notch there between, whereby a user grasps the bulbous handle member and rolls the planar body member forward on the wheeled axles to cut a sheet of material passing into said cutting notch.

12. The wheeled device for cutting sheet material according to claim 11 further comprising a third wheeled axle secured perpendicularly to said planar base member adjacent said front wheeled axle and coplanar therewith.

13. The wheeled device for cutting sheet material according to claim 11 further comprising a linear crossbar member positioned perpendicularly to said planar body member in an aperture in said bulbous handle member.

14. The wheeled device for cutting sheet material according to claim 13 wherein, said handle member aperture and linear crossbar member are positioned near an end of said bulbous handle member opposite said rear wheeled axle.

15. The wheeled device for cutting sheet material according to claim 13 wherein, said linear crossbar member is removeably positioned in said aperture in said bulbous handle member.

16. The wheeled device for cutting sheet material according to claim 11 wherein, said cutting notch is essentially parallel to said plane of said wheeled axles.

17. The wheeled device for cutting sheet material according to claim 11 wherein, said contained cutting blade member is removable from said planar body member.

18. The wheeled device for cutting sheet material according to claim 11 wherein, said contained cutting blade member is positioned on a centerline of said planar body member.

19. The wheeled device for cutting sheet material according to claim 11 wherein, said bulbous handle member is inclined at about 70 degrees to said plane of said wheeled axles.

20. A wheeled device for cutting sheet material comprising;

(a) a planar body member supported vertically on a front wheeled axle and a rear wheeled axle, said axles positioned in a plane and oriented perpendicularly to said vertical planar body member;

(b) said planar body member including a cutting notch with open and closed ends, said cutting notch oriented essentially parallel to said plane of said wheeled axles and positioned adjacent said front wheeled axle with open end forward thereof;

(c) said planar body member including a contained cutting blade member positioned on a center line thereof, with cutting edge exposed within said notch closed end; and

(d) a bulbous handle member secured to, and coplanar with, said planar body member, said handle member extending upwardly opposite said rear wheeled axle, said handle member and planar body member forming a grasping notch there between;

whereby a user grasps the bulbous handle member and rolls the planar body member forward on the wheeled axles to cut a sheet of material passing into said cutting notch.

21. The wheeled device for cutting sheet material according to claim 20 further comprising a third wheeled axle secured perpendicularly to said planar base member adjacent said front wheeled axle and coplanar therewith.
