Router template apparatus

A router template apparatus for routing stair stringers, said apparatus comprising:

• a rectangular frame member having an opening extending therethrough for receiving a router, said frame member comprising a pair of elongate side portions and a pair of elongate end portions;
• a pair of brace members being pivotally coupled to opposing corner portions of said frame member, each of said brace members being oriented generally parallel to each other when attached to said frame member;
• wherein when inside edges of said brace members are positioned adjacent to side edges of a stair stringer and said frame member is positioned atop a broad surface of the stringer, said opening guides the router to facilitate cutting out a recessed section in the stringer such that an end portion of a stair member is positionable in the recessed section to facilitate building a stairway;
• each of said portions of said frame member having an inner edge defining said opening;
• said inner edges of said portions of said frame member being adapted for abutting a guide lip of the router to permit a user to cut out the recessed section in the stringer;
• a pivot member for pivotally coupling a first of said brace members to a first of said opposing corner portions of said frame member;
• said frame member having a plurality of elongate slots extending therethrough for receiving a plurality of fastening members from each of said brace members, each of said slots being positioned in said opposing corner portions of said frame member and being oriented generally parallel to a diagonal axis extending between corresponding corners of said opposing corner portions;
• wherein each of said fastening members of said brace members are movably positionable in each of said slots such that each of said brace members is generally rotatable with respect to said frame member and laterally positionable in a manner so as to allow a distance between said brace members to be adjusted to accommodate stringers having different widths;
• said frame member having a hole extending therethrough for receiving a screw to allow the user to attach said frame member to the stringer during the cutting out of the recessed section in the stringer;
• said frame member having angle indicia positioned thereon for indicating angle settings for proper orientation of said frame member with regards to the stringer as dictated by predetermined dimensions of the stairway the stringer is to be utilized for;
• said angle indicia being located adjacent to said inner edge of a first of said side portions and being positioned between each of said end portions of said frame member;
• said first of said brace members having a step indicator positioned thereon, said step indicator being positioned adjacent to an inside edge of said first of said brace members, wherein said step indicator is aligned with step markings made by the user along the stringer to facilitate correct spacing of the stair members along the stinger;
• said angle indicia comprising a plurality of equally-spaced indicator lines, each of said indicator lines corresponding to angles representing an angular orientation of a line taken substantially perpendicular to a longitudinal axis of the stair members with regards to a longitudinal axis of the stair stringer;
• and
• wherein when one of said indicator lines of said angle indicia corresponding to a specific angle intersects said inside edge of said first of said brace members, the longitudinal axis of said first of said brace members and a longitudinal axis of said first of said side portions are oriented at an angle being substantially equal to the angle of said specific line indicator.
