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.

First claim

What is claimed:

1 . An adjustable T-square comprising:
a head portion with a body adapted to sit adjacent to a work surface; a ruler portion that is movable relative to the head portion; a locking mechanism operative to lock the ruler portion in a fixed position relative to the head portion; and an alignment mechanism.

2 . The adjustable T-square of claim 1 , comprising:
a pivot pin adapted to move the ruler portion relative to the head portion when the locking mechanism is disengaged.

3 . The adjustable T-square of claim 2 wherein the locking mechanism further comprises:
at least one locking pin.

4 . The adjustable T-square of claim 3 , wherein the at least one locking pin and pivot pin are operative to prevent movement of the ruler portion with respect to the head portion.

5 . The adjustable T-square of claim 1 , wherein the alignment mechanism further comprises:
at least one locking detent.

6 . The adjustable T-square apparatus of claim 5 , wherein the at least one locking detent comprises:
a body operatively engaged with a spring.

7 . The adjustable T-square apparatus of claim 6 , wherein the ruler portion has a first portion containing a plurality of angle apertures and a second portion.

8 . The adjustable T-square apparatus of claim 7 , wherein the plurality of angle apertures are operative to accept the at least one locking detent when at least a portion of the body is within the aperture and the spring is in its extended position.

9 . The adjustable T-square apparatus of claim 1 , further comprising:
a faceplate that extends partially over a first end of the ruler portion and is operatively connected to the head portion.

10 . The adjustable T-square apparatus of claim 9 , further comprising:
a channel formed by the faceplate and a top surface of the head portion operative to permit movement of the ruler portion within the channel.

11 . The adjustable T-square apparatus of claim 1 , wherein the ruler portion further comprises:
a first portion with an arced surface with a plurality of angle apertures.

12 . The adjustable T-square apparatus of claim 11 , wherein the first portion further includes a track operative to accept a portion of a locking pin.

13 . The adjustable T-square apparatus of claim 1 , wherein the head portion further comprises:
a plurality of indicia indicating angle of the ruler portion with respect to the head portion.

14 . The adjustable T-square apparatus of claim 1 , further comprising:
audible and tactile feedback members to operative to provide audible and tactile feedback to a user that the apparatus is set to a precise angle.

15 . A method for drawing a straight angled line comprising:
rotating a ruler portion of an adjustable T-square; aligning an alignment mechanism with angled indicia on a head portion of the adjustable T-square; engaging a locking mechanism at a precise angle preventing movement of the ruler portion with respect to the head portion; and using an edge of the ruler portion to draw a line with a writing implement at the precise angle.

16 . The method of claim 15 , wherein further comprising:
prior to rotating; disengaging a locking mechanism that allows the ruler potion to rotate with respect to the head portion.

17 . The method of claim 15 , wherein aligning further comprises:
interlocking at least one locking detent into an aperture on the ruler portion.

18 . The method of claim 15 , where rotating comprises:
rotating the ruler portion about a pivot point engaged with the ruler portion and the head portion.

19 . The method of claim 15 , where during rotating:
hearing audible feedback from the alignment mechanism to operative to provide audible feedback to a user; and feeling tactile from the alignment mechanism operative to provide tactile feedback to the user, whereby the audible and tactile feedback are operative to indicate to the user of a precise angle is engaged.

20 . The method of claim 15 , wherein prior to rotating:
abutting the head portion against a work surface.
