## Abstract

The invention relates to a device comprising a first part (1) provided with a base (11) and a rod (12) having an opening or recess (13) for the engagement of an actuation tool (3), a second part (2) provided with a through-opening (21) for mounting on the rod (12) of the first part (1) and a surface for supporting the tool (3), as well as a tool (3) of the second part (2) along the rod (12) of the first part (1). The tool (3) comprises: a first arm (31) and a second arm (32) hinged on an intermediate shaft (33), having respective ends (31a, 32a) for acting on the first part (1) and the second part (2), and respective handles (31b and 32b); a mechanism (4) for positioning and regulating the rotational relative movement of the arms (31, 32).

## Claims

### Claim 1

A device for levelling coating parts; applicable in the coplanar arrangement of said coating parts during the installation thereof; comprising: a first part (1) of the device provided with a base (11) and a rod (12) having at least one hole or recess (13) for the engagement of an actuation tool (3); a second part (2) provided with a through-opening (21) suitable for mounting on the rod (12) of the first part (1) and can be moved towards the base (11) thereof and with a surface for supporting the actuation tool (3); and an actuation tool (3) for moving the second part (2) along the rod (12) of the first part (1) towards an operative position in which the first part (1) and second part (2) exert a pressure on two opposite faces of at least two adjacent coating parts (P); characterized in that the actuation tool (3) comprises: a first arm (31) and a second arm (32) articulated on an intermediate shaft (33), having respective ends (31a, 32a) for acting on the first part (1) and the second part (2), and respective handles (31 b and 32b); a mechanism (4) for positioning of the arms (31, 32) of the tool in positions with different degrees of opening and for regulating the rotational relative movement of said arms (31, 32) in each of the said positions.

### Claim 2 (depends on 1)

The device according to claim 1, characterized in that the positioning mechanism (4) comprises: a separator (41) provided with a longitudinal slotted hole (42) in which a pin (34) of the first arm (31) of the tool is mounted and can be rotated and moved along the same; said separator (41) having on a first side an alignment of recesses (43) that define, in a coupling position with a secured tooth (35) of the second arm (32), relative positions of the arms (31, 32) of the tool (3) with different degrees of opening and; a spring (44) that acts with the opposite ends on the first arm (31) and the separator (41), said spring (44) tending to maintain the separator (41) in a coupling position in any one of the recesses (43) with the secured tooth (35) of the second arm (32) and to maintain the tool (3) in an inoperative position, determined by the contact of the pin (34) with said end of the slotted hole (42) farthest from the other arm (32) of the tool.
