Abstract
A template guide which performs and simplifies the task of layout for stair stringers. This accomplishment has previously been made by the use of multiple tools including the framing square, multipurpose square, and speed square as well as others. The said template of the present invention features an adjustable riser that can be secured for the exact dimension of any rise calculated to be between 6″ and 7¾″. The said template of the present invention also features an adjustable tread that can be secured for the exact dimension of any tread length, calculated to be between 9¼″ and 11⅛″. The said template is configured as such to accommodate the unskilled craftsman as well as the experienced tradesman.
Claims1
An adjustable stringer guide template comprising:
- a first section slidably connected to a second section;
- wherein said first section comprises a U-shaped member having first and second parallel legs and a perpendicular leg connecting the first and second parallel legs;
- wherein said second section comprises third and fourth parallel legs which slidably engage the first and second parallel legs of the first section, respectively;
- a fifth leg extending perpendicularly from the third parallel leg and away from the fourth parallel leg;
- a sixth leg extending perpendicularly from the fifth leg and parallel to the third leg;
- a seventh leg extending perpendicularly from the sixth leg and parallel to the fifth leg;
- and an angled member extending angularly from the fourth parallel leg of the second section and connected to the seventh leg;
- and a third section adjustably connected to said second section;
- wherein said third section comprises a U-shaped member having eighth and ninth parallel legs and a tenth perpendicular leg connecting the eighth and ninth parallel legs;
- said eighth and ninth parallel legs slidably engage said fifth and seventh parallel legs of said second section;
- wherein said first leg, second leg, and tenth leg include riser indicia thereon and said perpendicular leg of said first section includes tread indicia thereon;
- whereby sliding the first section relative to the second section adjusts the adjustable stringer guide template to a desired riser dimension of a stringer for a staircase;
- whereby sliding said third section relative to said second section adjusts the adjustable stringer guide template to a desired tread dimension of a stringer for a staircase.
