DETAILED DESCRIPTION

[0024] In the embodiment shown in FIGS. 1 to 3, the manual long-length ceramic cutter comprises a base 1 that defines a surface for supporting the ceramic pieces to be cut, a longitudinal guide (2) arranged in correspondence with a longitudinal median plane of the base (1) and installed at its ends on said base (1), and a head (3), manually movable along the guide (2), for scoring and separating the ceramic pieces positioned on the base (1).

[0025] In this embodiment, the manual cutter comprises a mobile support (4) installed at its upper end (41) installed on the mentioned guide (2) and at its lower end on longitudinal tracks (11a, 11b) defined on the sides of the base. (1).

[0026] The mentioned mobile support (4) is arranged behind the head (3), taking as a reference the direction of movement of said head (3) during the scoring of the ceramic pieces, and being able to move along the cutter.

[0027] As can be seen in FIG. 2, said mobile support (4) has at its upper end (41) a hole for the tight passage of the guide (2) and has two branches diverging towards the lower area, the lower end (42) of the mobile support (4) comprising respective slides (43) which move along the tracks (11a, 11b) of the base (1).

[0028] It should be mentioned that the skates (43) can be made up of a material with a low coefficient of friction, bearings or any other element that allows the smooth movement thereof along the tracks (11a, 11b).

[0029] This mobile support (4) can therefore be arranged at any intermediate point of the cutter, forming an intermediate support for the guide (2) with respect to the base (1), said mobile support preventing the guide (2) from bending during the marking/scoring of short-length ceramic pieces, due to the pressure exerted by the head (3) on the guide (2).

[0030] The cutter includes immobilisation means for immobilising the mobile support (4) at any point of its travel, and which act either on the guide (2) or on the base (1). In this specific embodiment, said means are made up of threaded knobs (44) for immobilising the slides (43) with respect to the tracks (11a, 11b) of the base.

[0031] In the embodiment variant shown in FIGS. 4 to 6, the manual long-length ceramic cutter comprises two parallel longitudinal guides (2a, 2b), installed at their ends on the base (1), and a head (3) for scoring and separating the ceramic pieces, operable manually and installed on the guides (2a, 2b) that can move longitudinally.

[0032] In this embodiment, the cutter comprises two mobile supports (4a, 4b) arranged one on each side of the slicer and installed at the upper end (41) thereof in the corresponding guide (2a, 2b) and at the lower end (42) thereof in a track (11a, 11b) defined on the corresponding side of the base (1).

[0033] Said mobile supports (4a, 4b) can be moved longitudinally along the cutter and are arranged, as in the previous embodiment, behind the head (3), taking as a reference the direction of movement of said head during the scoring of the ceramic pieces.

[0034] As can be seen in greater detail in FIG. 6, the mobile supports (4a, 4b) have at their upper end (41) a hole for the tight passage of the corresponding guide (2a, 2b) and at their lower end (42) a slide (43) housed in the corresponding track (11a, 11b) of the base (1) of the cutter.

[0035] Said mobile supports (4a, 4b), which form elements for attaching the longitudinal guides (2a, 2b) with the base (1), prevent said longitudinal guides from bending in the area for positioning said mobile supports (4a, 4b), guaranteeing a correct operation of the cutter when scoring and cutting short-length ceramic pieces, that is, a length that is considerably less than the total length of the guides (2a, 2b).

[0036] In this embodiment, the cutter comprises means for fixing the mobile supports (4a, 4b) at any point of their travel, represented, as in the previous embodiment, by threaded knobs (44) that allow the tightening of the slides (43) against the respective tracks (11a, 11b), locking the mobile supports (4a, 4b) in the desired position.

[0037] Having sufficiently described the nature of the invention, in addition to a preferred exemplary embodiment, it is hereby stated for the relevant purposes that the materials, shape, size and layout of the described elements may be modified, provided that it does not imply altering the essential features of the invention claimed below.
