Abstract

A manual ceramic cutter with an adjustable set-square, having a set-square (1) installed at one of the longitudinal extremities of a base (2) for supporting the ceramic items to be cut, and a manually-operated cutting head (3) installed with the possibility of displacement along a number of longitudinal guides (4). This cutter comprises adjustment means (13, 14) of the perpendicularity of the set-square (1) with regard to a cutting line (L1) of the cutter, and fixing means (11, 12) of the set-square (1) to the base (2). It further comprises visual verification means of the perpendicularity of the set-square (1) with regard to the cutting line (L1).

First claim

The invention claimed is:

1. A manual ceramic cutter, comprising:
a set-square installed on a longitudinal extremity of a base configured to support ceramic items to be cut, and defining a lateral supporting line for the ceramic item to be cut;
a manually-operated cutting head displaceable along a number of longitudinal guides;
an adjustment device configured to adjust perpendicularity of the set-square with respect to a cutting line of the cutter; and
a fixing device configured to fix the set-square to the base;
wherein the adjustment device comprises an elastic element that acts on the set-square to rotate it on the set-square on a rotation axis towards a side of the base, and a manual adaptation screw configured to rotate the set-square on the rotation axis in an opposite direction to the action of the elastic element;
wherein the rotation axis is a lateral rotation axis of the set-square with respect to the base.

2. The manual ceramic cutter, according to claim 1 , wherein the fixing device of the set-square comprises at least one fixing screw installed on the base of the cutter through an elongated hole defined in the set-square and configured to provide lateral rotation of the set-square with respect to the rotation axis prior to tightening the at least one fixing screw.

3. The manual ceramic cutter according to claim 1 , further comprising a visual verification device configured to indicate perpendicularity of the set-square with respect to the cutting line, the visual verification device comprising:
a longitudinal mark defined at the base of the cutter and parallel to the cutting line;
a viewer fixed to the set-square, and aligned with the longitudinal mark of the base when the set-square is arranged perpendicular to the cutting line.

4. The manual ceramic cutter according to claim 2 , further comprising a visual verification device configured to indicate perpendicularity of the set-square with respect to the cutting line, the visual verification device comprising:
a longitudinal mark defined at the base of the cutter and parallel to the cutting line;
a viewer fixed to the set-square, and aligned with the longitudinal mark of the base when the set-square is arranged perpendicular to the cutting line.
