Abstract
A compression nut assembly is provided including a base nut and a compression nut. The base nut includes a base shaft having an interior surface and an exterior surface. The interior surface of the base shaft includes a plurality of internal threads extending in a first handedness direction. The compression nut includes a compression shaft having an interior surface and an exterior surface. The exterior surface of the compression shaft includes a plurality of external threads extending in the first handedness direction and engagable with the internal threads of the base shaft. The interior surface of the compression shaft includes a plurality of internal threads extending in a second handedness direction opposite the first handedness direction.
Claims20
A compression nut assembly comprising:
- a base nut including a base shaft having an interior surface and an exterior surface, the interior surface of the base shaft including a plurality of internal threads extending in a first handedness direction;
- a compression nut including a compression shaft having an interior surface and an exterior surface, the exterior surface of the compression shaft including a plurality of external threads extending in the first handedness direction and engagable with the internal threads of the base shaft, the interior surface of the compression shaft including a plurality of internal threads extending in a second handedness direction opposite the first handedness direction.
A compression nut assembly comprising:
- a base nut including a base plate having a first surface and a second surface, and a base shaft extending from the first surface of the base plate, the base shaft having an interior surface and an exterior surface, the interior surface of the base shaft including a plurality of internal threads extending in a first handedness direction;
- a compression nut including a compression plate having a first surface and a second surface, and a compression shaft extending from the first surface of the compression plate, the compression shaft having an interior surface and an exterior surface, the exterior surface of the compression shaft including a plurality of external threads extending in the first handedness direction and engagable with the internal threads of the base shaft, the interior surface of the compression shaft including a plurality of internal threads extending in a second handedness direction opposite the first handedness direction.
A method for expanding a compression nut assembly between a first object and a second object, comprising:
- threadedly engaging a compression nut with a base nut, the compression nut including a plurality of external threads engaging a plurality of internal threads of the base nut, the base nut fixed to the first object, the compression nut movable between a retracted state and an extended state;
- threadedly engaging a fastener with a plurality of internal threads of the compression nut;
- rotating the fastener in a first direction to move the compression nut toward the extended state until the compression nut extends entirely between a space provided between the first object and the second object;
- and
- rotating the fastener in the first direction such that the fastener further engages the compression nut.
