Abstract
A drywall cutting tool is described. The drywall cutting tool has an elongated flat ruler with a knife blade and a handle attached to one end of the elongated flat ruler. A support bracket that has a flat top portion with a flange along one side and a pair of guides on the top. The guides receive the one end of the ruler allowing the ruler to slide along the top portion of the support bracket to any desired measurement length. A screw-down hand is also attached to the support bracket to pinch and secure the ruler at the guides so that the desired measurement length is maintained.
Claims20
A drywall cutting tool comprising:
- an elongated flat ruler (20) having first (24) and second ends (25);
- a knife blade (23) with a handle (21) attached to the first end (24) of the ruler (20);
- a support bracket (1) having a flat top portion with a flange (9) along one side;
- a pair of guides (2) on the top portion of the support bracket configured to receive the second end (25) of the ruler and allow the ruler to slide along the top portion of the support bracket (1) to any desired measurement length;
- a screw-down handle (3, 4, 10) attached to the top portion of the support bracket configured to pinch and secure the ruler (20) in the guides at the desired measurement length;
- whereby, the tool allows the support bracket to be placed on an edge of a drywall sheet (30) and the knife blade (23, 23a, 23b, 23c) to be positioned at the desired measurement length so that the drywall sheet may be cut at the desired measurement length by moving the support bracket and the knife blade (23) together along the drywall sheet.
A tool for cutting drywall sheets (30) comprising:
- a rigid flanged plate (1, 9) having an attached pair of parallel guide tracks (2) on an upper surface, the flanged plate also having a screw-down clamp handle (3, 4, 10) located between the parallel guide tracks;
- an elongated flat member (20) configured to slide between the parallel guide tracks (2) and be locked down by the screw-down clamp handle (3), the elongated flat member including a retractable knife blade (23) attached (22) to a distal end;
- wherein, when the flanged plate is placed on an edge of a drywall sheet (30), the elongated flat member (20) may be slid in the parallel guide tracks to establish a desired distance onto the sheet (30) for cutting and then locked down with the screw-down clamp handle (3) to maintain the desired distance during cutting.
A drywall cutting tool used to make precision cuts in drywall sheets (30) that includes a flat ruler (20) with an attached knife blade (23) and knife handle (21) on a first end (24), the flat ruler cooperating with a flanged end support (1) to allow the flanged end support to slide along an edge of a drywall sheet during cutting, the flanged end support constructed to allow the flat ruler to be clamped (10) to the flat end support at a desired cutting distance placing the knife blade (23) at the desired cutting distance from the said edge of the drywall sheet (30).
