Cutting and separating device applicable to manual ceramic cutters

Abstract

The invention relates to a cutting and separating device applicable to manual ceramic cutters, comprising: a carriage; a collapsible handle with a cutting tool; a toothed part comprising a separator for separating ceramic parts; springs for holding the toothed part in an inoperative position as well as a toothed actuator in an engaged position with the toothed part; and a manual trigger element for disengaging the toothed actuator. The rotation of the handle past a pre-determined angle causes the engagement of the toothed actuator in the toothed part; the descending rotation causes the toothed actuator to rotate the toothed part until an operative position of the separator is reached; and the actuation of the trigger element causes the release of the toothed part and the return thereof to the inoperative position.

Claims

1. A cutting and separating device applicable to manual ceramic cutters; said cutting and separating device comprising a carriage that can move longitudinally with respect to the cutter and provided with a transverse shaft on which a collapsible handle is mounted comprising a cutting tool the cutting and separating device comprising: a toothed part comprising a separator for separating ceramic parts, mounted on the transverse shaft of the handle with the possibility of rotating between: an operative position in which the separator goes beyond the cutting plane of the tool and an inoperative position in which said separator does not reach the cutting plane of the tool; a spring which acts on the toothed part for holding the toothed part in an inoperative position; a toothed actuator mounted on the handle, a spring which acts on said toothed actuator for maintaining the tooth actuator in an engaged position with the toothed part and one or more trigger elements for disengaging the toothed actuator with respect to the toothed part; said one or more manual trigger elements arranged such that: rotating the handle in an ascending direction, above a predetermined angle, causes the toothed actuator to automatically engage in the toothed part; rotating the handle in a descending direction causes the toothed actuator to rotate the toothed part until reaching an operative position of the separator; and the actuation of one of the one or mare manual trigger elements causes the release by the toothed actuator of the toothed part which automatically returns to the inoperative position.

2. The device, according to claim 1, wherein the toothed part or the toothed actuator have a toothed section with successive teeth for the mutual engagement thereof in different relative positions.

3. The cutting and separating device, according to claim 1, wherein the carriage has lugs housed in curved eyelets of the toothed part and which form stop means of the toothed part between the operative and inoperative positions.

4. The device, according to claim 1 wherein the separator is suspended from the toothed part with the possibility of free rotation, by means of a second transverse shaft parallel to the transverse shaft of the rotation of the handle and the toothed part.

5. The device, according to claim 1, wherein the trigger element of the toothed actuator comprises an actuation trigger near a grip for gripping the handle and a cable or rod for connecting the trigger to said toothed actuator.

Description

DESCRIPTION OF THE FIGURES

(1) As a complement to the description being made, and for the purpose of helping to make the characteristics of the invention more readily understandable, this specification is accompanied by a set of drawings which, by way of illustration and not limitation, represent the following.

(2) FIGS. 1 and 2 show a elevation view and a perspective view of an exemplary embodiment of the cutting and separating device for ceramic parts mounted on a manual cutter for ceramic parts.

(3) FIGS. 3, 4, 5 and 6 each show elevation views of the cutting and separating device; in an operative cutting position; in an engaged position of the actuator with the toothed part; in an actuation position of the separator; and in a position of releasing the toothed part comprising the separator by the toothed actuator, respectively.

PREFERRED EMBODIMENT OF THE INVENTION

(4) As can be seen in FIGS. 1 and 2, this cutting and separating device comprises a carriage (1) which can move longitudinally on guides of a manual ceramic cutter arranged on top of a base or support surface for the ceramic parts to be cut.

(5) This carriage (1) has a transverse shaft (2) on which a handle (3) comprising a cutting tool (4) and a toothed part (5) comprising a separator for the ceramic parts are mounted with the possibility of rotation.

(6) The toothed part (5) has curved eyelets (7) which house lugs (8) defined on the carriage (1) and which limit the rotation of the toothed part (5) between an inoperative position represented in FIGS. 3, 4 and 6 and an operative position represented in FIG. 5.

(7) The separator (6) is suspended from the toothed part (5) with the possibility of free rotation by means of a second transverse shaft (9) parallel to the transverse shaft (2) of the rotation of the handle (3) and the toothed part (5).

(8) Acting on the aforementioned toothed part (5) is a spring (10) for holding it in an inoperative position.

(9) On the front end of the handle a toothed actuator is mounted by means of a rotational shaft (11) on which a spring (13) acts to hold it in an engaged position with the toothed part (5).

(10) In the example shown, both the toothed part (5) and the toothed actuator (12) have opposing toothed sections for the engagement thereof with a greater or smaller number or teeth based on the thickness of the ceramic part to be separated.

(11) The aforementioned toothed actuator (12) is connected to a manual trigger element that allows it to be disengaged from the toothed part (5) and which is made up of an actuation trigger (14) near the grip (15) of the handle and connected to said toothed actuator (12) by means of a cable or rod (16). The proximity of the actuation trigger (4) to the grip allows for the actuation thereof with a finger of the same hand used for holding the handle, which significantly simplifies the use of the cutting and separating device for ceramic parts.

(12) With these characteristics, when the toothed actuator is disengaged from the toothed part (5), the spring (10) arranges the toothed part (5) in an inoperative position, represented in FIG. 3 and in which the separator (6) does not reach the cutting plane of the cutting tool (4).

(13) As shown in FIG. 4, when the handle is rotated towards the upper area, going beyond a predetermined angle, the teeth of the toothed actuator (12) engage with the teeth of the toothed part (5) and by subsequently rotating the handle (3) in a descending manner, as shown in FIG. 5, the toothed actuator (12) causes the rotation of the toothed part (5) until reaching an operative apposition in which the separator goes beyond the cutting plane of the tool, allowing the separation of the previously marked ceramic part.

(14) After performing the separation of the ceramic part, it is enough to just press the trigger (14) for the toothed actuator (12) to release the toothed part (5) and the same returns by the action of the spring (10) to the inoperative position, the device remaining in the cutting position.

(15) 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.
