Abstract
A checker nut for locking a threaded body to a threaded rod, comprises a main body portion having a top bearing surface for engaging a threaded body. The main body portion includes a central opening with an inside surface. A female thread is disposed on the inside surface and extends therefrom, the female thread for cooperating with threads on a threaded rod; and the female thread is disposed on the inside surface a distance from the top bearing surface equal to at least one thread required to be passed by a threaded body on a threaded rod.
Claims41
A checker nut for locking a threaded body to a threaded rod, comprising:
- a) main body portion having a top bearing surface for engaging a threaded body;
- b) the main body portion including a central opening with an inside surface;
- c) a female thread disposed on the inside surface and extending therefrom, the female thread for cooperating with threads on a threaded rod;
- and
- d) the female thread is disposed on the inside surface a distance from the top bearing surface equal to at least a thread portion required to be passed by the threaded body on the threaded rod such that the female thread will not engage the threaded rod if the at least a thread portion required to be passed by the threaded body is not present on the threaded rod.
A checker nut as in 1, wherein the female thread includes gaps.
A checker nut for locking a threaded body to a threaded rod, comprising:
- a) main body portion having a top bearing surface for engaging a threaded body;
- b) the main body portion including a central opening;
- c) a female thread disposed in the central opening, the thread for cooperating with threads on a threaded rod;
- d) a stop member disposed at a bottom portion of the central opening;
- e) the stop member extending radially toward the central opening;
- and
- f) the stop member including a top surface configured to engage a bottom surface of a threaded rod to which the checker nut is to be threaded.
A concrete reinforcement assembly, comprising:
- a) a threaded rod;
- b) an anchor body threaded to the rod;
- c) a checker nut engaged tight against the anchor body to lock the anchor body in place;
- d) the checker nut including a main body portion having a central opening with a cylindrical inside surface;
- e) a female thread disposed on the cylindrical inside surface and extending therefrom, the female thread for cooperating with threads on the threaded rod;
- and
- f) the female thread is disposed on the cylindrical surface a distance from the top bearing surface equal to at least one thread required to be passed by the anchor body on the threaded rod.
A concrete reinforcement assembly, comprising:
- a) a threaded rod;
- b) an anchor body threaded to the rod;
- c) a checker nut engaged tight against the anchor body to lock the anchor body in place;
- d) the checker nut including a main body portion having a central opening;
- e) a female thread disposed in the central opening, the thread for cooperating with threads on the threaded rod;
- f) a stop member disposed at a bottom portion of the central opening;
- g) the stop member extending radially toward the central opening to engage a bottom surface of the threaded rod;
- h) the central opening including an inside cylindrical surface;
- i) the female thread extending from the cylindrical surface;
- and
- j) the female thread is disposed a distance on the cylindrical surface from the stop member equal to a number of threads on the threaded rod required to be passed by the anchor body.
A checker nut for locking a threaded body to a threaded rod, comprising:
- a) a body having a top bearing surface for engaging a threaded body;
- b) the body including a central opening;
- c) a female thread disposed in the central opening, the thread for cooperating with threads on a threaded rod;
- d) the body extending beyond the outer periphery of a threaded body to be locked by the checker nut on a threaded rod to provide leverage to a user to tighten the top bearing surface against the threaded body;
- and
- e) the body being deformable to develop tension in the threaded rod between the thread and the top bearing surface when the body is tightened against the threaded body.
