Cutting and separation head for manual ceramics cutters
A cutting and separation head for manual ceramic cutters, including a body that carries a grip handle and a cutting tool, mounted on movable supports on longitudinal guides of the cutter, and able to rotate with respect to a first transverse rotary shaft; a separator provided with a foot, a class 1 lever, and a first coupling element in the separator that is couplable to a second coupling element in the body of the head; and a cam for releasing the first and second coupling elements, the cam being mounted on the body and relatively rotatable between a first position and a second position.
1. A cutting and separation head for manual ceramic cutters comprising:
movable supports on longitudinal guides of a cutter; a body mounted on supports that can be rotatably moved with respect to a first transverse rotary shaft, a grip handle secured to a first end of the body, a cutting tool and a separator provided with a support foot on the ceramic parts to be separated, further comprising:
a class 1 lever mounted on a second transverse rotary shaft, the lever of which has a first end on which the foot of the separator is articulated and a second, opposite end;
a first coupling element articulated on the second end of the lever;
at least one spring that acts on the first coupling element and tends to rotated the first coupling element towards a coupling position with a second coupling element defined in the body of the head, establishing coupling of the first coupling element to the second coupling element and the separator being disposed in an operative position, when the body of the head is folded in an ascending direction, exceeding a first angle of inclination with respect to the horizontal and is maintained at an inclination smaller than a second larger angle; and
a cam for releasing the first and second coupling elements, the cam being mounted on the body and relatively rotatable between a first position and a second position, wherein the cam acts on the first coupling element, releasing the first coupling element from the second coupling element when the body is folded in an ascending direction and reaches the second angle, maintains the first coupling element away from the path of the second coupling element when the body of the head is folded in a descending direction and, and releases the first coupling element, the separator being disposed in an inoperative position when the body of the head reaches an inclination smaller than the first angle.
2. The head according to claim 1 , wherein the cam is mounted on the first rotary shaft of the body and limited with relative rotation with respect to the body along the path of a stop attached to the body, along an inside of a curved slot defined in the cam.
3. The head according to claim 1 , wherein the second larger angle is greater than 70°.
4. The head according to claim 3 , wherein the second larger angle is 105°.
