Abstract

A wheeled dolly for transporting and/or storing a floor sander to maintain the rubber tired wheels of the sander in a no load state and thereby preventing flat spots from forming in the tires resulting in variations in the depth of sanding process. Also disclosed is a dolly with a hand operable brake for selectively restraining rotation of at least one of the dolly wheels.

Claims

1. A hand truck for transporting a conventional floor sander that is rollingly supported on a plurality of rubber tired wheels extending below a frame of said sander during use of the machine to sand a floor, comprising:

an upwardly projecting frame with handle means on the upper end thereof, a forwardly projecting load carrying member defining a pair of laterally spaced apart arms projecting forwardly therefrom on the lower end of said upwardly projecting frame and a pair of wheels on opposite edges of said lower end of said upwardly projecting frame adjacent the lower end thereof;

said handle means comprising members extending forward from said upwardly projecting frame;

means removably mounted on said arms and supporting said sander on said hand truck forwardly projecting arms with said plurality of rubber tired wheels of said sander in a no load state and thereby preventing the rubber tired wheels from developing flat spots during idle time of the machine while in storage and transport from one work site to another;

said means removably mounted on said arms for supporting said sander comprising at least one cross member defining a sliding frame support means slidably mounting on and extending from one of said arms to the other; and

means detachably anchoring said sander to said hand truck.

2. The hand truck of claim 1, wherein said sliding frame support means comprises a pair of cross members slidably mounted on said arms.

3. The hand truck of claim 1 including means interconnecting said pair of arms to maintain the same in a fixed spaced apart relation.

4. The hand truck of claim 3, wherein said means interconnecting said arms comprises a strap.

5. The hand truck of claim 2, wherein said cross members have a slot adjacent each of opposite ends thereof slidably receiving therein respective ones of the forwardly projecting arms.

6. The hand truck of claim 1, including means for braking at least one of said wheels.

7. The hand truck of claim 1 including means for braking said at least two wheels.

8. The hand truck of claim 1, including at least one laterally spaced apart endless track projecting from a rear face of said upright frame portion of said hand truck at a position adjacent the lower end thereof.

9. The hand truck of claim 1, wherein said handle means comprises a laterally spaced pair of loops on an upper end of said upwardly projecting frame.

10. The hand truck as defined in claim 1, wherein each of said arms are right angular in cross-section.

11. The hand truck as defined in claim 1 including a pair of cross members slidably mounted on and extending from one of said arms to the other for supporting an object thereon.

12. The hand truck of claim 1, wherein the space between said pair of arms is greater than the width of said floor sander.

13. The hand truck of claim 6, wherein said means for braking comprises a hand operated brake operable on at least one of said wheels to selectively restrain rotation of the same, said brake having a hand operable lever mounted on said frame adjacent said handle means.

14. The hand truck of claim 8, including a hand operated brake cooperatively engaging said endless track for selectively restraining movement thereof.

15. A hand truck and floor sander assembly, comprising:

a floor sander that is rollingly supported on a plurality of rubber tired wheels during use;

an upwardly projecting frame portion with forwardly projecting handle means on the upper end thereof, a forwardly projecting load carrying member defining a pair of spaced apart arms projecting forwardly therefrom on the lower end of said frame portion and a pair of wheels on opposite edges of said lower end of said frame portion adjacent the lower end thereof;

means removably mounted on said arms and supporting said sander on said hand truck forwardly projecting arms with said plurality of rubber tired wheels of said sander in a no load sate and thereby preventing the rubber tires wheels from developing flat spots during idle time of the machine while in storage and transport from one work site to another; and

means detachably anchoring said sander to said hand truck.

16. The hand truck and floor sander assembly of claim 15, wherein said means removably mounted on said arms define a sliding frame support means comprising a pair of cross members slidably mounted on said arms.

17. The hand truck and floor sander assembly of claim 16, wherein said cross members have a slot adjacent each of opposite ends thereof slidably receiving therein respective ones of the forwardly projecting arms.

18. The hand truck and floor sander assembly of claim 15, including means interconnecting said pair of arms to maintain the same in a fixed spaced apart relation.

19. The hand truck and floor sander assembly of claim 18, wherein said means interconnecting said arms comprises a strap.

20. The hand truck and floor sander assembly of claim 15, including means for braking at least one of said wheels.

21. The hand truck and floor sander assembly of claim 20, wherein said means for braking comprises a hand operated brake operable on at least one of said wheels to selectively restrain rotation of the same, said brake having a hand operable lever mounted on said frame adjacent said handle means.

22. The hand truck and floor sander assembly of claim 15, including means for braking said at least two wheels.

23. The hand truck and floor sander assembly of claim 15, including at least one laterally spaced apart endless track projecting from a rear face of said upright frame portion at a position adjacent the lower end thereof.

24. The hand truck and floor sander assembly of claim 15, wherein said handle means comprises a laterally spaced pair of loops on an upper end of said upwardly projecting frame portion.

25. The hand truck and floor sander assembly as defined in claim 15, wherein each of said arms are right angular in cross-section.

26. The hand truck and floor sander assembly as defined in claim 15, wherein the space between said pair of arms is greater than the width of said floor sander.
