- This invention relates to an insert for a staircase. More specifically, this invention relates to an insert for a staircase spindle having a square cavity.
- Staircases having a railing and spindles extending therebetween are old and well known in the art.
- Many conventional spindles have a cylindrical end. Constructing a staircase using these spindles is very easy as the builder simply drills a round hole with a conventional drill bit of the corresponding size to receive the spindle in the desired location on the staircase. Then the builder places the spindle in the cylindrical opening made by the drill. This process is more difficult when the spindle end is square.
- a builder does not have a square drill and instead will drill a round hole having a diameter large enough to receive the square end of the spindle. The hole is then filled with epoxy to hold the spindle in place. Often the epoxy breaks down, or the builder neglects to use epoxy and the spindle will rotate. Therefore, there exists a need in the art for a device that addresses these needs.

Abstract
An insert for receiving the square end of a staircase spindle having a top, a generally cylindrical sidewall, a bottom, and a generally square bore that extends generally through the center of the inset.
Description
- This application claims the benefit of U.S. Provisional Application No. 61/153,685 filed Feb. 19, 2009.
- This invention relates to an insert for a staircase. More specifically, this invention relates to an insert for a staircase spindle having a square cavity.
- Staircases having a railing and spindles extending therebetween are old and well known in the art. Many conventional spindles have a cylindrical end. Constructing a staircase using these spindles is very easy as the builder simply drills a round hole with a conventional drill bit of the corresponding size to receive the spindle in the desired location on the staircase. Then the builder places the spindle in the cylindrical opening made by the drill. This process is more difficult when the spindle end is square. Typically, a builder does not have a square drill and instead will drill a round hole having a diameter large enough to receive the square end of the spindle. The hole is then filled with epoxy to hold the spindle in place. Often the epoxy breaks down, or the builder neglects to use epoxy and the spindle will rotate. Therefore, there exists a need in the art for a device that addresses these needs.
- Therefore, an object of the present invention is to provide an insert that permits the easy installation of a spindle with a square end.
- This and other objectives will be apparent to one skilled in the art based on the following disclosure.
- An insert having a top, a bottom, and a sidewall, extending generally through the center of the insert is a bore that receives the square end of a staircase spindle. A fastener connects the insert to the staircase.
-
FIG. 1 is a top plan view of an insert; and -
FIG. 2 is a sectional side view of an insert. - Referring to the Figures, the
insert 10 has atop 12, acylindrical sidewall 14, and abottom 16. Extending generally through the center of the insert is abore 18. The bore is generally square and is sized to receive thesquare end 20 of astaircase spindle 22. Preferably, the bore is ½ inch across. - The
sidewall 14 is generally cylindrical and is sized to fit within ahole 24 made by a conventional round drill bit. Preferably, thesidewall 14 is ¾ inch high and theinsert 10 is 1⅛ inches across. - In operation, a
hole 24 is drilled on the edge of a stairstep with a conventional round drill bit. Once thehole 24 is made, theinsert 10 is placed within thehole 24 and thesquare end 20 of thespindle 22 is placed in thebore 18. Thespindle 22 is then rotated to the desired position and theinsert 10 is secured in place with afastener 26 such as by pounding a nail through theinsert 10 and into thewood base 28 below. With thespindle 22 positioned within thebore 18, and theinsert 10 secured in place with thefastener 26, thespindle 22 will not rotate. - Thus, an insert has been disclosed that at the very least meets the stated objective.
