Abstract

An example shut-off device includes a valve body to surround a section of a pipe and form a chamber about the section of the pipe. The example shut-off device also includes a first flange bearing on a first side of the chamber. The first flange bearing in a closed position forming a first seal between the pipe and the chamber. The example shut-off device also includes a second flange bearing on a second side of the chamber. the second flange bearing in a closed position forming a second seal between the pipe and the chamber. The example shut-off device also includes a cutting blade in the chamber. The cutting blade tightens against the pipe to cut through the pipe and at least partially seals an opening in the cut pipe. The cutting blade is configured to operate as a gate valve.

Claims

1. A pipe repair device comprising:

a molded sleeve section including a contiguous strike; and

a molded handle section including a contiguous draw hook, the molded handle section connected to the molded sleeve section with a first living hinge, the draw hook to selectively engage with the strike when the pipe repair device is applied to a damaged pipe.

2. The pipe repair device of claim 1, wherein the entirety of the pipe repair device is of a monolithic construction.

3. The pipe repair device of claim 1, wherein the molded sleeve section includes:

a first molded sleeve section including the contiguous strike; and

a second molded sleeve section connected to the first molded sleeve with a sleeve living hinge.

4. The pipe repair device of claim 1, wherein the molded sleeve section is compressively wrapped around the damaged pipe and maintained in a tensioned condition when the pipe repair device is applied to the damaged pipe.

5. The pipe repair device of claim 1, wherein the molded handle section includes:

a first molded handle section connected to the molded sleeve section with the first living hinge; and

a second molded handle section including the contiguous draw hook connected to the first molded handle section with a handle living hinge.

6. The pipe repair device of claim 5, wherein the first molded handle section is maintained in a compressed condition and the second molded handle section is maintained in a tensioned condition when the pipe repair device is applied to the damaged pipe.

7. The pipe repair device of claim 1, wherein the pipe repair device is made of a resiliently elastic material that forms a seal against the damaged pipe when the pipe repair device is applied to the damaged pipe.

8. The pipe repair device of claim 1, further comprising:

a resiliently elastic gasket that forms a seal against the damaged pipe when the pipe repair device is applied to the damaged pipe.

9. The pipe repair device of claim 1, wherein the molded sleeve section and the molded handle section each include a harder exterior layer and a softer interior layer.

10. The pipe repair device of claim 1, cut from a lengthy extruded section.

11. The pipe repair device of claim 1, further comprising:

a lock that prevents a user from releasing the pipe repair device from a locked position without releasing the lock.

12. The pipe repair device of claim 1, wherein the molded sleeve section occupies greater than 50% of a circumference of the damaged pipe.

13. The pipe repair device of claim 1, wherein the pipe repair device is entirely of a resiliently elastic material.

14. A method of using a pipe repair device comprising:

placing a molded sleeve section around a damaged pipe;

engaging a contiguous strike of the molded sleeve section with a contiguous draw hook of a molded handle section, the molded handle section connected to the molded sleeve section with a first living hinge; and

applying compressive force to the molded handle section to lock the pipe repair device to the damaged pipe.

15. A pipe repair device comprising:

a first molded sleeve section including a contiguous strike;

a second molded sleeve section connected to the first molded sleeve with a sleeve living hinge;

a first molded handle section connected to the molded sleeve section with a living hinge; and

a second molded handle section including a contiguous draw hook, the second molded handle section connected to the first molded handle section with a handle living hinge, the draw hook to selectively engage with the strike when the pipe repair device is applied to a damaged pipe.

16. The pipe repair device of claim 15, wherein the first molded sleeve section and the second molded sleeve section are compressively wrapped around the damaged pipe and maintained in a tensioned condition when the pipe repair device is applied to the damaged pipe.

17. The pipe repair device of claim 15, wherein the first molded handle section is maintained in a compressed condition and the second molded handle section is maintained in a tensioned condition when the pipe repair device is applied to the damaged pipe.

18. The pipe repair device of claim 15, wherein the entirety of the pipe repair device is of a monolithic construction.

19. The pipe repair device of claim 15, wherein the pipe repair device is made of a resiliently elastic material that forms a seal against the damaged pipe when the pipe repair device is applied to the damaged pipe.

20. The pipe repair device of claim 15, further comprising:

a resiliently elastic gasket that forms a seal against the damaged pipe when the pipe repair device is applied to the damaged pipe.
