Abstract:
1. A leveling device for placing of flat pieces for covering surfaces, comprises: a first lower substantially flat body configured for placement under the flat covering pieces, a flexible post emerging from an upper surface of said first lower substantially flat body perpendicular to the first lower substantially flat body and substantially centered on the first lower substantially flat body, such that the flexible post emerges between two of the flat covering pieces to be leveled by the leveling device; and a second upper body which has a passage configured for receiving and holding said flexible post until exerting a pressure against the flat covering pieces when it is brought close to the first lower substantially flat body, aligning said flat covering pieces; the flexible post further comprising a portion configured to allow for its withdrawal, wherein the flexible post has a rectangular cross section with opposite main surfaces thereof further comprising a first set of teeth positioned on a first main surface and a second set of teeth positioned on a second main surface, wherein the first and second sets of teeth are offset in a lengthwise direction along a length of the flexible post with respect to each other; and wherein the passage of the second body includes two latching pawls opposed one another so that in an operative position of the device, the teeth of each of the two opposite first and second sets of teeth on the flexible post alternately engage with said pawls, permitting high precision control of the advancement movement and the pressure exerted by the first lower substantially flat body and the second upper body on the aligned covering pieces, and wherein the second upper body is bell shaped with a lower widened contact mouth or border configured to distribute pressure on the flat covering pieces.
