    4. The guiding device, according to any of the preceding claims, characterised in that the body of the guide (1) is made up of removable guide segments (1a, 1b) which comprise at their opposite ends: respective longitudinal holes (152, 153), close to the first side (13) and to the second side (14), in which coupling pins (16) are housed; and securing means (17) in a coupling position.

    5. The guiding device, according to any of the preceding claims, characterised in that the securing means (17) for securing the guide segments (1a, 1b) comprise a hook (171) and a lever lock (172), couplable to said hook, secured on the base (112) of the intermediate recessed portion (111) of the top surface (11) of the guide.

    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0021] As a complement to the description provided herein, and for the purpose of helping to make the features 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:

    [0022] FIG. 1 shows a partial perspective view of an exemplary embodiment of the guiding device for large-format cutters, according to the invention.

    [0023] FIG. 2 shows a profile view of the device of the previous figure, secured on a large-format part to be cut.

    [0024] FIG. 3 shows a view similar to the previous one in which a manual cutter mounted on the guiding device of the invention has been represented.

    [0025] FIG. 4 shows a partial perspective view of two aligned and disassembled guide segments.

    [0026] FIG. 5 shows a perspective view of one of the guide segments which form the guide.

    DETAILED DESCRIPTION

    [0027] The guiding device of the invention has been represented in FIG. 1, comprising an extruded aluminium guide (1) made up of two guide segments (1a, 1b) attached together by means of securing means (17) and on which lever suction cups (2) are mounted for securing same on the large-format part (P) to be cut.

    [0028] As shown in FIG. 2, the guide (1) comprises a top surface (11) and a bottom surface (12) between which hollow chambers (15) separated by reinforcing ribs (151) are defined.

    [0029] The top surface (11) comprises an intermediate recessed portion (111), provided with a base (112) and laterally delimited by surfaces which form mutually facing longitudinal rails (113a, 113b) for the movement of rolling means (32) of a manual cutter (3) represented in FIG. 3 and provided with a cutting tool (31) for the marking of a break line on the part (P) to be cut; so that the rolling means (32) are located within the intermediate recessed portion (111).

    [0030] The bottom surface (12) of the guide (1) has on a first side (13) first means (121, 122) for support on the part (P) to be cut, and on a second side (14) a longitudinal recess (123) for receiving the suction cups (2) which form second means for supporting and securing the guide (1) on the part (P) to be cut.

    [0031] As can be seen in FIGS. 2 and 3, the longitudinal rails (113a, 113b) for the movement of the cutter are located between the first support means (121, 122) and the suction cups (2) which form the second support means of the guide on the part (P) to be cut.

    [0032] The first support means (121, 122) are made up of bottom appendages (121) of the aluminium guide, internally provided with respective longitudinal lips (122) of an elastomer or anti-slip material, coplanar with the securement surface for securing the suction cups (2) to the part (P) to be cut.

    [0033] The guide (1) has on the second side (14) slots (141) that are longitudinally aligned and in correspondence with the vertical median plane of the longitudinal recess (123) for the longitudinal reception of the suction cups (2), rods (21) being housed in said slots (141) rods which are coupled to levers (22) for driving and locking the suction cups with respect to the part (P) to be cut. The aforementioned levers (22) are arranged above the guide (1).

    [0034] The guide segments (1a, 1b) which form the body of the guide (1) have longitudinal holes (152, 153) referenced in FIG. 2 at the opposite ends, close to the first and to the second sides (13, 14) of the guide (1) and, in which coupling pins (16) visible and referenced in FIGS. 4 and 5 are housed.

    [0035] The securing means (17) for securing the successive guide segments (1a, 1b) in the coupling position, comprise a hook (171) and a lever lock (172) secured on the base (112) of the intermediate recessed portion (111) of the top surface of the guide. Said securing means (17) can be operated simply by pressing, once the lever lock (172) has been hooked on the hook (171).

    [0036] 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.
