Separator Device Applicable to Manual Ceramic Cutters

Abstract

Separator device applicable to manual ceramic cutters, which comprises: a tilting lever (2) and an actuation cam (3) provided with a cam profile (3) with a non-uniform variation in its radius of curvature and that provides a variable relationship between the rotation of the cam and the movement of the first end of the tilting lever, depending on the rotational position of the cam, in such a way that:—when the cam (3) rotates (β1) with a certain amplitude in an initial segment of its path, the first end of the tilting lever (2) completes a movement (d1) of a certain length; and—when the cam rotates (β2), with the same amplitude as β1, but in the final segment of its path, the first end of the tilting lever (2) completes a movement (d2) that is longer than the movement (d1).

Claims

1. Separator device applicable to manual ceramic cutters and in particular, to cutters provided with a support base (1) for the ceramic piece (P), the separator device comprising: a tilting lever (2) provided with a first end (22) and a cam (3) provided with a curved profile for actuating that tilting lever (2); characterized in that: the cam profile (3) has a non-uniform variation in its radius of curvature and it provides a variable relationship between the rotation of the cam and the movement of the first end of the toggle lever (2), depending on the rotational position of the cam (3) between two possible end positions of its own rotation, in such a way that: when the cam (3) rotates (β1) with a certain amplitude in an initial segment of its path, the first end (22) of the tilting lever (2) completes a movement (d1) of a certain length; when the cam rotates (β1) with the same amplitude as (β1). in a final segment of its path, the first end (22) of the tilting lever (2) completes a movement (d2) that is longer than the movement (d1); the device transmits a greater force to the tilting lever (2) in the initial segment of the rotation of the cam (3), in other words, when the thicker ceramic pieces (P) are bring broken; and a lesser force in the final segment of the rotation of the cam (3), when the thinner pieces (P) are being broken.

Description

DESCRIPTION OF THE FIGURES

[0013] As a complement to the description provided herein, and for the purpose of helping to make the characteristics of the invention more readily understandable, the present specification is accompanied by a set of drawings constituting an integral part of the same, which, by way of illustration and not limitation, represent the following:

[0014] FIG. 1 shows a schematic elevation view of an exemplary embodiment of the separator device applicable to manual ceramic cutters object of the invention during the partition of a thick piece of ceramic and the actuation of the cam with a first segment of the cam profile against the cam follower of the tilting lever.

[0015] FIG. 2 shows a view similar to the preceding figure during the partition of a thinner ceramic piece and the actuation of the cam with the final segment of the cam profile against the tilting lever follower.

[0016] FIG. 3 shows an elevation view of the cam of the preceding figures.

[0017] FIG. 4 shows a graph of the rotation/movement relationship of the cam of the separator device of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

[0018] In FIGS. 1 and 2, one can schematically observe an exemplary embodiment of the separator device of the invention provided with a support base (1) for the ceramic piece (P) to be separated, said base being provided with a small protrusion (11) in the support area of the ceramic piece (P) upon which a cutting line will have been previously marked via a cutting device (not shown).

[0019] The separator device comprises a tilting lever (2) mounted on a rotation shaft (21) and an actuation cam (3).

[0020] The tilting lever (2) tends to rest in a non-operating position due to the action of a spring (4), said tilting lever (2) having a first end with support legs (22) on the portions of the ceramic piece to be separated and, on the opposite end, a cam follower (23) that is pressed against the cam profile (3) via the spring (4).

[0021] This cam (3) is mounted on a rotation shaft (31) and is actuated by a rotating actuation handle (not shown).

[0022] In FIG. 3 it can be observed that the cam profile (3) has a non-uniform variation in its radius of curvature, for which reason it provides a variable relationship between the rotation of the cam and the movement of the first end of the tilting lever, depending on the rotational position of the cam between two possible end positions of its own rotation.

[0023] As can be seen in the graph in FIG. 4, corresponding to the relationship between the rotation of the cam and the movement of the first end of the tilting lever: - when the cam rotates (β1) with a certain amplitude in an initial segment of its path, the first end of the tilting lever (2) completes a movement (d1) of a certain length; and—when the cam rotates (β2), with the same amplitude as (β1), but in the final segment of its path, the first end of the tilting lever (2) completes a movement (d2) that is longer than the movement (d1).

[0024] This determines that the device transmits a greater force to the tilting lever (2) in the initial segment of the rotation of the cam (3), in other words, when the thicker ceramic pieces (P) are being broken; and a lesser force in the final segment of the rotation of the cam, when the thinner pieces (P) are being broken.

[0025] Having sufficiently described the nature of the invention, in addition to an example of preferred 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 characteristics of the invention claimed below.
