Claims
- 1. An attachment device for attaching a support post to a floor having a top, a bottom, and a floor opening between the top and the bottom, the attachment device comprising:a floor locking nut configured to be movably supported at the bottom of the floor to engage a protrusion of the support post extending through the floor opening, the floor locking nut including a nut bearing surface disposed adjacent a nut aperture and facing downward from the bottom of the floor, the nut bearing surface including an inclined surface leading to a raised surface which is raised with respect to the bottom of the floor, the floor locking nut being movable relative to the protrusion to change contact from a first contact position between the inclined surface and the protrusion to a second contact position between the raised surface and the protrusion.
- 2. The attachment device of claim 1 wherein the floor locking nut further includes a stop disposed on a side of the raised surface opposite from the inclined surface.
- 3. The attachment device of claim 1 wherein the floor locking nut includes a serrated outer periphery.
- 4. The attachment device of claim 3 wherein the serrated outer periphery includes a plurality of slanted teeth.
- 5. The attachment device of claim 1 wherein the nut aperture is elongated in one direction.
- 6. The attachment device of claim 1 wherein the floor locking nut is rotatable relative to the protrusion in a first direction to change contact from the first contact position to the second contact position.
- 7. The attachment device of claim 6 wherein the floor locking nut is rotatable relative to the protrusion in a second direction opposite from the first direction to change contact from the second contact position to the first contact position.
- 8. An attachment device for attaching a support post to a floor having a top, a bottom, and a floor opening between the top and the bottom, the attachment device comprising:a floor locking nut configured to be rotatably supported at the bottom of the floor to engage a protrusion of the support post extending through the floor opening, the floor locking nut including a pair of nut bearing surfaces disposed on opposite sides of a nut aperture and facing downward from the bottom of the floor, the nut aperture being elongated in one direction, the two nut bearing surfaces each including an inclined surface leading to a raised surface, both in either a clockwise direction or a counterclockwise direction with respect to the nut aperture, the floor locking nut being movable relative to the protrusion to change contact from a first contact position between the inclined surfaces and the protrusion to a second contact position between the raised surfaces and the protrusion.
- 9. The attachment device of claim 8 wherein the floor locking nut further includes two stops each disposed on a side of one of the raised surfaces opposite from the inclined surface leading to the raised surface.
- 10. The attachment device of claim 8 wherein the two nut bearing surfaces are curved to form circular segments on opposite sides of the nut aperture.
- 11. The attachment device of claim 8 wherein the two raised surfaces are substantially planar with one another.
- 12. The attachment device of claim 8 wherein the floor locking nut includes a serrated outer periphery.
- 13. The attachment device of claim 8 wherein the floor locking nut is rotatable relative to the protrusion in a first direction to change contact from the first contact position to the second contact position.
- 14. The attachment device of claim 13 wherein the floor locking nut is rotatable relative to the protrusion in a second direction opposite from the first direction to change contact from the second contact position to the first contact position.
