Abstract

A carpet removal or stripping method and system (machine) employs a common dolly. The backside of the dolly member has a plurality of teeth. A motorized winching system is coupled to the front side of the dolly member. A dual purpose safety shield covers the teeth during transportation and serves as a protective screen for the user during carpet removal operation of the invention machine. The winching system automates carpet peeling activity with the dolly member lying backside down during operation, and the teeth provide an anchoring effect. A pull bar removably grasps the subject carpet. A cable is coupled between the winching system and the pull bar. The winching system takes up or pulls the cable and hence the pull bar, such that the carpet is peeled away and separated from the subfloor.

Claims

1. A carpet removal system comprising:

a dolly member having a front side and back side opposite the front side, the back side bearing a plurality of teeth;

a motorized winching system coupled to the front side of the dolly member; and

a safety shield that covers the teeth during transportation and serves as a protective screen for the user during carpet removal operation of the system, the winching system enabling automated carpet peeling activity with the dolly member lying backside down during operation and the teeth providing an anchoring effect.

2. A carpet removal system as claimed in claim 1 wherein the dolly member has prongs protruding from the front side;

and

the safety shield is removably attached to the prongs to serve as a protective screen for the user during carpet removal operation.

3. A carpet removal system as claimed in claim 1 further comprising a pull bar removably grasping a subject carpet;

and

the winching system includes a cable removably coupled to the pull bar, during operation, the winching system taking up the cable and hence the pull bar such that the subject carpet is peeled away from a subfloor.

4. A carpet removal system as claimed in claim 3 wherein the pull bar has a length between about 2 feet and 4 feet.

5. A carpet removal system as claimed in claim 1 wherein the dolly member is a common dimensioned dolly, such that the carpet removal system fits through residential passageways and doorways.

6. A carpet removal system as claimed in claim 1 wherein the winching system includes an electric winch.

7. A carpet removal system as claimed in claim 6 wherein the electric winch is attached to a plate that is secured to the front side of the dolly member.

8. A carpet removal system as claimed in claim 1 wherein the plurality of teeth are provided by a plurality of framing plates lining the back side of the dolly member.

9. Given carpet affixed to a subfloor, a method for separating the carpet from the subfloor comprising the steps of:

providing a dolly member having a front side and back side opposite the front side, the back side bearing a plurality of teeth;

coupling a motorized winching system to the front side of the dolly member;

covering the teeth with a safety shield during transportation of the dolly member and using the safety shield as a protective screen for the user during operation of the winching system; and

operating the winching system to automate carpet peeling activity with the dolly member lying backside down during operation and the teeth providing an anchoring effect.

10. A method as claimed in claim 9 wherein the dolly member has prongs protruding from the front side;

and

the safety shield is removably attached to the prongs to serve as a protective screen for the user during carpet removal operation.

11. A method as claimed in claim 9 further comprising the step of using a pull bar, removably grasping a subject carpet;

and

removably coupling a cable between the pull bar and the winching system, during operation, the winching system taking up the cable and hence the pull bar such that the subject carpet is peeled away from a subfloor.

12. A method as claimed in claim 11 wherein the pull bar has a length between about 2 feet and 4 feet.

13. A method as claimed in claim 9 wherein the dolly member is a common dimensioned dolly, such that the carpet removal system fits through residential passageways and doorways.

14. A method as claimed in claim 9 wherein the winching system includes an electric winch.

15. A method as claimed in claim 9 wherein the plurality of teeth are provided by a plurality of framing plates lining the back side of the dolly member.

16. Carpet removal apparatus comprising:

dolly means having a front side and back side opposite the front side, the back side including anchoring means;

winching means coupled to the front side of the dolly member; and

a dual purpose shield means for covering the anchoring means during transportation and serving as a protective screen for the user during carpet removal operation of the apparatus, the winching means enabling automated carpet peeling activity with the dolly member lying backside down during operation and providing an anchoring effect.

17. Apparatus as claimed in claim 16 wherein the anchoring means includes a plurality of teeth.

18. Apparatus as claimed in claim 16 wherein the dolly member has prongs protruding from the front side;

and

the dual purpose shield means is removably attached to the prongs to serve as a protective screen for the user during carpet removal operation.

19. Apparatus as claimed in claim 16 further comprising a pull bar removably grasping a subject carpet;

and

the winching means includes a cable removably coupled to the pull bar, during operation, the winching means taking up the cable and hence the pull bar such that the subject carpet is peeled away from a subfloor.

20. Apparatus as claimed in claim 16 wherein the winching means includes a motorized winch.
