Description

    FIELD OF THE INVENTION
  • The present invention relates generally to plumbing fixture drainage systems, and more particularly to a drain nut, tool, and method for installing the drain nut onto a drain pipe, thereby securing the drain pipe to the plumbing fixture.
  • BACKGROUND OF THE INVENTION
  • Conventionally, drain assemblies are secured to plumbing fixtures, such as, kitchen, bathroom and utility room lavatories or sinks by means of a nut disposed on the underside of a sink. The drain nut is threadably engaged on a relatively large diameter, hollow tubular, externally threaded pipe that extends from the drain downwardly through an opening in the bottom of the sink.
  • The drain assembly typically includes an annular collar which surrounds the drain, resting atop and about the periphery of an opening through the bottom portion of the sink. The drain pipe extends downwardly through the opening past the underside surface of the sink. The drain assembly is secured by engaging the drain nut with the drain pipe and manually advancing the drain nut the full length of the drain pipe, until the drain nut resides in abutment against the undersurface of the sink.
  • The drain nut is initially tightened by hand. However, in order to adequately secure the drain assembly to the sink a tool, such as a basin wrench or a channel lock wrench, is utilized to advance the drain nut to firmly secure the drain nut against the underside of the sink. However, due to the space limitations engaging the drain nut with the tool can be a difficult and time consuming process.
  • Thus, there exists a need for a system and method for attaching a drain assembly to a plumbing fixture.
  • SUMMARY OF THE INVENTION
  • The present invention provides a drain connection kit for connecting a drain pipe to a plumbing fixture. A drain nut is provided which includes first and second bores and an annular wall with a threading. The annular wall threading is configured and dimensioned to threadably engage the drain pipe exterior threading. A driver tool is provided for engaging the drain nut to rotate the drain nut onto the drain pipe. The driver tool has a first extension configured and dimensioned to removably engage the first bore and a second extension configured and dimensioned to removably engage the second bore, such that rotation of the driver tool rotates the drain nut.
  • The present invention also provides a plumbing fixture, wherein the plumbing fixture can be a sink, lavatory, tub, shower, or any other receptacle or vessel having a drain. The plumbing fixture includes a drain port defining a passage extending through an upper surface to an underside surface of the plumbing fixture. A drain pipe having first and second ends and an exterior threading is included. The drain pipe is positionable through the passage, with the second end of the drain pipe extending past the underside surface of the plumbing fixture. A drain ring is affixed to the first end of the drain pipe, which is positionable about the upper surface of the plumbing fixture, surrounding the drain port. A drain nut is provided which includes first and second bores and an annular wall with a threading. The annular wall threading is configured and dimensioned to threadably engage the drain pipe exterior threading. A driver tool is provided for engaging the drain nut to rotate the drain nut onto the drain pipe. The driver tool has a first extension configured and dimensioned to removably engage the first bore and a second extension configured and dimensioned to removably engage the second bore such that rotation of the driver tool rotates the drain nut.

  • Referring now to the drawings in which like reference designators refer to like elements, there is shown in FIGS. 1 and 2 a drain connector kit 10 of the present invention, including a drain assembly 12. The drain assembly 12 includes a drain ring 14 connected to an externally threaded drain pipe 16. The drain connector kit 10 includes a drain nut 20 to threadably engage the drain pipe 16. A drain nut driver 22 is utilized to drive and thread the drain nut 20 onto the threaded drain pipe 16.
  • Referring to FIGS. 3 and 4, the drain nut 20 includes a flange portion 24 and a nut portion 26. The flange portion 24 includes a pair of bores 28 and 30 configured and dimensioned to be engaged by the drain nut driver 22. The drain nut 20 is internally threaded 32 for engagement to the drain pipe 16. While the drain nut 20 is shown having a pair of bores 28 and 30, it is contemplated that the drain nut 20 can include any number of bores. These bores can be opposingly, uniformly, symmetrically, or asymmetrically positioned about the flange portion 24 of the drain nut 20. Additionally, the bores 28 and 30 are depicted having a circular cross sectional area. However, it is contemplated that the cross sectional area of bores 28 and 30 can have other shapes, including, but not limited to, rectangular, triangular, elliptical, octagonal, hexagonal, diamond, star, etc, and combinations thereof.
  • Referring to FIG. 5, the drain nut driver 22 includes a drain nut engaging structure 34. The drain nut engaging structure 34 is substantially U-shaped, having a pair of extensions 36 and 38. The extensions 36 and 38 are provided in a spaced apart relationship for alignment with the pair of bores 28 and 30 in the drain nut 20. The extensions 36 and 38 are shaped, sized, and dimensioned to one each slidingly engage the bores 28 and 30.
  • The extensions 36 and 38 are depicted having a circular cross sectional area. However, it is contemplated that the cross sectional area of a extensions 36 and 38 can have other shapes, including but not limited to, rectangular, triangular, elliptical, octagonal, hexagonal, diamond, star, etc., matching the cross sectional area of the bores 28 and 30. In the instance where the drain nut 20 includes multiple pairs of bores, the extensions 36 and 38 may be selectively positioned in any one of the pairs of bores.
  • The drain nut engaging structure 34 is affixed to a drive shaft 40. The drive shaft 40 is configured for engagement by a driver unit (not shown), such as a mechanical or electric driver. For example, the drive shaft 40 may have substantially hexagonal cross section area for insertion into and engagement by a chuck of the electric drill. Upon securement of drive shaft 40 in the drill chuck, activation of the electric drill rotates the drain nut engaging structure 34. The electric driver can be used to rotate the drain nut engaging structure 34 in either a clockwise or counter-clockwise direction.
