Abstract
An adjustable T-square device and method of use is shown and described herein. The adjustable T-square has a plurality of apertures with at least one locking detent to set precise angles. The adjustable T-square has a locking pin to further engage a ruler portion to a head portion to minimize error when using the device.
Claims20
An adjustable T-square comprising:
- a head portion with a body adapted to sit adjacent to a work surface;
- a ruler portion movable relative to the head portion, wherein the ruler portion has a first portion and a second portion, and the first portion defines a plurality of angle apertures therein;
- a locking mechanism operative to lock the ruler portion in a fixed position relative to the head portion;
- and
- an alignment mechanism including at least one locking detent having a detent body operatively engaged with a spring;
- and
- wherein an aperture of the plurality of angle apertures is operative to accept the at least one locking detent when at least a portion of the detent body is received within the aperture and the spring is in an extended position.
4 more elements
A method for drawing a straight angled line comprising:
- rotating a ruler portion of an adjustable T-square;
- aligning an alignment mechanism of the adjustable T-square with angled indicia on a head portion of the adjustable T-square;
- engaging a locking mechanism of the adjustable T-square at a precise angle to prevent movement of the ruler portion with respect to the head portion;
- using an edge of the ruler portion to draw a line with a writing implement at the precise angle;
- and
- wherein during rotating:
- hearing audible feedback from the alignment mechanism which is operative to provide audible feedback to a user;
- and
- feeling tactile feedback from the alignment mechanism which is operative to provide tactile feedback to the user, wherein the audible feedback and the tactile feedback indicate to the user that the precise angle is engaged.

An adjustable T-square comprising:
- a head portion including a first surface and a second surface, wherein the first surface is adapted to rest adjacent an edge of a work piece, and the second surface is arranged at right angles to the first surface;
- a recess defined in the second surface of the head portion, wherein the recess originates in the first surface and extends inwardly into the head portion and away from the first surface, and wherein the recess includes an arcuate section;
- angle indicia provided on the second surface of the head portion in the arcuate section of the recess;
- a ruler portion comprising a first portion and a second portion;
- wherein the first portion is received within the arcuate section of the recess of the head portion;
- wherein the second portion extends outwardly from the first portion and beyond the first surface of the head portion;
- a pivot pin extending between the ruler portion and the head portion, said pivot pin enabling pivotal motion of the ruler portion relative to the head portion;
- and
- a locking mechanism extending between the ruler portion and the head portion a distance away from the pivot pin, said locking mechanism being movable between an engaged position and a disengaged position, and when the locking mechanism is in the engaged position, pivotal motion of the ruler portion relative to the head portion is prevented.
