Set square for manual ceramic cutter

Abstract

A set square for manual ceramic cutters, including a ruler intended to be rotatably mounted and secured to a base of a manual ceramic cutter, defining various angles; a stop that is mounted on the ruler and can be moved longitudinally; and a tightening element for securing to the ruler. The cross-section of the ruler includes two oblique planes that converge towards an intermediate surface provided with a longitudinal recess having a generally T-shaped cross section, for mounting the tightening element. The lateral stop includes two oblique planes facing the ruler and having the same slope as the oblique planes of the ruler, and which converge towards an intermediate surface that has an opening to mount the tightening element.

Claims

1. A set square for manual ceramic cutters comprising: a ruler rotatably mounted and secured to a base of a manual ceramic cutter, defining various angles; a stop that is mounted on the ruler and can be moved longitudinally and a tightening element for securing the lateral stop to the ruler; wherein the cross-section of the ruler comprises two oblique planes that converge towards an intermediate surface provided with a longitudinal recess having a generally T-shaped cross section, for mounting the tightening element; the lateral stop comprises two oblique planes facing the ruler and having the same slope as the oblique planes of the ruler, and which converge towards an intermediate surface that has an opening to mount the tightening element, and wherein the intermediate surface of the lateral stop has a width smaller than the intermediate surface of the ruler, such that contact between the ruler and the lateral stop is established between the oblique planes of the ruler and the oblique planes of the lateral stop.

2. The set square according to claim 1, wherein the securing element comprises: a head that is housed and can be moved and not rotated in the longitudinal recess of the ruler; a threaded rod that passes through the hole of the lateral stop; and a tightening knob mounted on said threaded rod.

3. The set square according to claim 1, wherein one of the oblique planes of the ruler converges with a plane parallel to the shaft of the tightening element and is extended along the ruler; and one of the oblique planes of the stop converges with a plane that, in the securing position of the stop to the ruler, it is arranged in parallel and very close to the plane of the ruler, preventing the relative rotation thereof.

4. The set square according to claim 1, wherein the lateral stop has a first section that defines the oblique planes in contact with the ruler and a second section articulated on the first section by a rotary shaft.

Description

DESCRIPTION OF THE FIGURES

(1) 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, which, by way of illustration and not limitation, represent the following:

(2) FIG. 1 shows a perspective view of an exemplary embodiment of the set square according to the invention mounted on a manual ceramic cutter.

(3) FIG. 2 shows a partial elevation view of the cutter of the previous figure, in which the mounting of the lateral stop on the ruler of the set square and a detailed enlargement of the coupling zone of both parts can be observed.

(4) FIG. 3 shows the previous figure in detail at a larger scale and with the lateral stop dismounted from the ruler.

(5) FIG. 4 shows a perspective view of the set square mounted on a manual ceramic cutter, with the lateral stop articulated by the intermediate rotary shaft.

PREFERRED EMBODIMENT OF THE INVENTION

(6) In the exemplary embodiment shown in FIG. 1, the set square of the invention is shown mounted on a manual ceramic cutter is shown in its entirety as C.

(7) The set square is made up of a ruler (1), a lateral stop (2) mounted on it which can be moved longitudinally, and a tightening element (3) for securing the lateral stop (2) in the desired position along the ruler (1).

(8) As shown in FIGS. 2 and 3, the cross-section of the ruler (1) comprises two oblique planes (11, 12) that converge towards an intermediate surface (13) facing in this case the upper zone and provided with a longitudinal recess (14) having a generally T-shaped cross section for mounting the tightening element (3).

(9) Moreover, the lateral stop (2) comprises two oblique planes (21, 22) facing the ruler (1) and having the same slope as the oblique planes (11, 12) of the ruler (1), and which converge towards an intermediate surface (23) of a width smaller than the intermediate surface (13) of the ruler (1), such that contact between the ruler (1) and the lateral stop is established by means of the oblique planes (11, 12) and (21, 22), respectively.

(10) The lateral stop (2) has on the intermediate surface (23) a hole (24) to mount the tightening element (3), which comprises a head (31) that is housed and can be moved and not rotated in the longitudinal recess (14) of the ruler (1), a threaded rod (32) that passes through the hole (24) of the lateral stop (2), and a tightening knob (33) mounted on said threaded rod.

(11) The actuation of the oblique planes (21, 22) of the lateral stop (2) on the oblique planes (11, 12) of the ruler (1) ensures that upon actuating the tightening element (3), the contact zones of the ruler and the lateral stop center themselves, thus preventing said lateral stop from moving in all directions.

(12) In the example shown in the figures, one of the oblique planes of the ruler (1) is spread along a plane (15) parallel to the shaft of the tightening element (3) and is extended along the ruler (1); one of the oblique planes of the lateral stop being spread on a plane (25) that, in the securing position of the stop (2) to the ruler, it is arranged in parallel and very close to the plane (15) of the ruler, preventing the relative rotation thereof.

(13) In the example shown, the lateral stop (2) has a first section (2a) that defines the aforementioned oblique planes (21, 22) in contact with the ruler (1) and a second section (2b), articulated on the previous one by means of a rotary shaft (26) that allows them to be aligned, as shown in FIGS. 1 and 2, or a variable angle forming therebetween, as shown in FIG. 4, to facilitate the fastening of the small ceramic parts.

(14) 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.
