    Description

    Object of the invention



    [0001] The object of the present invention relates to a cutting and separating device applicable to manual ceramic cutters, said cutting device comprising a carriage that can move longitudinally with respect to the cutter and provided with a transverse shaft on which a collapsible handle comprising the cutting element is mounted.

    [0002] This device comprises a mechanism to actuate the separator for separating the ceramic part marked by the cutting tool, both the cutting tool and the separator being actuated by a single handle.

    Field of application of the invention



    [0003] This invention is applicable in the field of manufacturing manual ceramic cutters, and specifically to cutting and separating devices for ceramic parts applicable to said manual cutters.

    State of the art



    [0004] Manual ceramic cutters that have a base on which guides for longitudinal movement and a cutting tool are mounted for marking a cutting line on the ceramic parts placed on the base of the cutter are currently known.

    [0005] These cutters also have a separator that, when actuated, acts on the previously marked ceramic part, causing the breaking of the same along the cutting line.

    [0006] With regard to these manual ceramic cutters, it is necessary to differentiate those in which the separator is independent from the cutting tool from those in which the separator and the cutting tool are included in the same head, such that once the cut or marking of the ceramic part has been made with the cutting tool, the integrated separator must be actuated to separate the ceramic part into two parts.

    [0007] The cutters of this second group, which have a device with a cutting tool and a separator on a same carriage or head, are the ones that have a stronger relationship with the device of the present invention. A few noteworthy examples may be found in the following documents:

    [0008] Document ES 1044402 U discloses a cutting and separating device as per the preamble of claim 1.

    [0009] In document ES 0295592 U, the separator and the cutting tool are mounted directly on a front end of the actuation handle and distanced along the same; making it necessary to move the cutting tool outside of the support area for the ceramic part in order to be able to actuate the separator. This prior art also has the drawback in that the direct actuation of the separator by means of the handle requires the application of substantial force to achieve the separation of the previously marked ceramic part.

    [0010] Document ES 2101611 of the same holder as the present invention describes a cutting and separating machine for flat ceramic parts and similar, wherein the cutting tool is mounted directly on the handle and the separator is actuated by the handle by means of a set of levers that must be manually arranged in a specific position when the separator is actuated by rotating the handle.

    [0011] This actuation mechanism has the drawback in that, in addition to actuating the handle, the user has to manipulate the set of levers to arrange the separator in an operative or inoperative position.

    [0012] Document ES 1042563 U of the same holder as the present invention describes a cutting and separating machine for flat ceramic parts, wherein the cutting tool is fixed to the handle and the separator is collapsible and actuated by means of the movement along the handle of the positioning mechanism connected to the separator by means of a connecting rod.

    [0013] In this case, the operator must use both of their hands to grip the handle and for actuating the positioning mechanism of the separator for separating ceramic parts.

    [0014] Document ES 1018011 U, also of the same holder of the present invention, describes a machine for cutting ceramic parts with a linear guide on bearings in which the separator of the parts is actuated by the handle by means of a connecting rod, while the cutting tool must be manually positioned in an operative position or an inoperative position by tilting a support part of said tool.

    [0015] In this case, just like in the previous cases, it is also necessary to secure the handle and manipulate the cutting tool to arrange it in a position of use or in an inoperative position.

    [0016] One additional drawback of these cutting and separating devices for ceramic parts is that in a position of use the separator is kept in a specific relative position with respect to the handle, not envisaging an adjustment that would allow for different relative positions based on the thickness of the ceramic part to be separated.

    Description of the invention



    [0017] The cutting and separating device applicable to manual ceramic cutters, object of the present invention, has some particular constructive features aimed at allowing the actuation of the cutting tool and the separator merely by means of the actuation of the handle, and by using just one hand, which significantly simplifies the actuation thereof with respect to the aforementioned prior art.

    [0018] Another objective of the invention is to allow for different relative positions between the handle and the separator when the same is in an operative position, and choosing a relative position based on the thickness of the ceramic part to be separated.

    [0019] To this end, and in accordance with the invention, this cutting and separating device comprises the combination of features of claim 1.

    [0020] With these characteristics, the cutting and separating device can be actuated in a simple and easy manner by the operator by using just one hand, only having to play with different rotations of the handle in an ascending and descending direction.

    [0021] To allow for the choice of different relative positions between the handle and the separator when the same is operative, it has been envisaged that the toothed part and/or the toothed actuator has a toothed section with several teeth to mutually engage in different relative positions, such that in actuating the separator by rotating the handle towards the lower area, said separator protrudes to a greater or lesser degree from the plane of the cutting tool as a function of the thickness of the ceramic part to be separated.

    [0022] These characteristics and other characteristics of the invention will be more easily understood in light of the exemplary embodiment shown in the figures attached.

    Description of the figures



    [0023] 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.
    • Figures 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.
    • Figures 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



    [0024] As can be seen in figures 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.

    [0025] 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.

    [0026] 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 figures 3, 4 and 6 and an operative position represented in figure 5.

    [0027] 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).

    [0028] Acting on the aforementioned toothed part (5) is a spring (10) for holding it in an inoperative position.

    [0029] 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).

    [0030] 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.

    [0031] 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.

    [0032] 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 figure 3 and in which the separator (6) does not reach the cutting plane of the cutting tool (4).

    [0033] As shown in figure 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 figure 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.

    [0034] 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.

    [0035] 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 within the scope of the appended claims.
