Abstract

There is disclosed an apparatus and a method for measuring an opening dimension. The apparatus may comprise a handle or a handle mounting portion and a rod holder adjustably attached to the handle or handle mounting portion. The method may comprise the use of the apparatus to measure an opening dimension.

Claims (47)

1. A method for measuring a dimension of an opening, the method comprising

providing a pre-sized rod;

providing a rod holder attached to a handle, said rod holder configured for holding said pre-sized rod; and

comparing the length of said pre-sized rod to the opening dimension to thereby measure said opening dimension.

2. The method according to claim 1 wherein said rod holder is adjustably attached to said handle so that the orientation of said rod is adjustable relative to said handle.

3. The method according to claim 2 wherein said rod holder is hingedly attached to said handle.

4. The method according to claim 3 wherein said hinged attachment comprises more than one hinge joint.

5. The method according to claim 1 wherein said opening is in a confined space.

6. The method according to claim 5 wherein said opening is a pipe end.

7. The method according to claim 1 further comprising providing more than one of said rods having differing lengths.

8. The method according to claim 7 wherein said dimension is a diameter and said measuring comprises selecting an individual one of said more than one rods whose rod length closely corresponds to the opening diameter.

9. The method according to claim 8 wherein the opening is a pipe end and the method is for discriminating between pipes of selected possible diameters.

10. The method according to claim 2 wherein said handle is telescopic.

11. An apparatus for measuring an opening dimension, said apparatus comprising

a handle;

a handle mounting element including

a connector element pivotally connected to said handle for movement relative to said handle, and

a rod holder mounting element pivotally connected to said connector element for movement relative to said connector element; and

a rod holder attached to said rod holder mounting element.

12. The apparatus according to claim 11 further comprising at least one presized said rod, wherein said rod holder is adapted to securely hold said at least one rod.

13. The apparatus according to claim 12 wherein said securing is by a screw, thumb screw or a clip.

14. The apparatus according to claim 11 wherein said handle is telescopic.

15. The apparatus according to claim 12 further comprising a plurality of presized rods having different rod lengths.

16. A kit for measuring a dimension of an opening, said kit comprising a handle with a rod holder hingedly mounted thereon.

17. The kit according to claim 16 further comprising more than one presized said rods, said rods sized for holding by said rod holder.

18. The apparatus according to claim 11 wherein movement of said connector element relative to said handle is in a plane.

19. The apparatus according to claim 11 wherein movement of said rod holder mounting element relative to said connector element is in said plane.

20. The apparatus according to claim 11 wherein said pivoting connection comprises a plurality of hinges.

21. The apparatus according to claim 20 wherein said hinges are lockable.

22. The apparatus according to claim 11 wherein said rod holding element defines a channel sized to accept a cooperating presized rod and configured to secure the cooperating rod therein.

23. The apparatus according to claim 22 wherein said adaptation for securing the rod comprises a screw, thumb screw or clip.

24. The apparatus according to claim 23 wherein said pivoting connection comprises a plurality of optionally lockable hinges.

25. The apparatus according to claim 24 wherein said handle is telescopic.

26. An apparatus for measuring a dimension of an opening, the apparatus comprising

a handle;

a pre-sized rod;

a rod holder attached to said handle, said rod holder configured for holding said pre-sized rod,

wherein the length of said pre-sized rod is compared to the opening dimension for measuring said opening dimension.

27. The apparatus according to claim 26 wherein said rod holder is adjustably attached to said handle so that the orientation of said rod is adjustable relative to said handle.

28. The apparatus according to claim 27 wherein said rod holder is hingedly attached to said handle.

29. The apparatus according to claim 28 wherein said hinged attachment comprises more than one hinge joint.

30. The apparatus according to claim 26 wherein said opening is in a confined space.

31. The apparatus according to claim 30 wherein said opening is a pipe end.

32. The apparatus according to claim 26 further comprising providing more than one of said rods having differing lengths.

33. The apparatus according to claim 32 wherein said dimension is a diameter and said measuring comprises selecting an individual one of said more than one rods whose rod length closely corresponds to the opening diameter.

34. The apparatus according to claim 33 wherein the opening is a pipe end and the apparatus is for discriminating between pipes of selected possible diameters.

35. The apparatus according to claim 27 wherein said handle is telescopic.
