Abstract

The present invention relates to a protective device for ceramic pieces, said device suitable for resting on the upper surface of at least two ceramic pieces ( 40, 41 ) and which forms a bearing surface for a tightening element ( 204, 305 ) of a spacer-leveller device ( 20, 30 ) for ceramic pieces. The protective device comprises: a lower bearing surface ( 101 ) on the ceramic pieces ( 40, 41 ) to be installed; an upper surface ( 102 ) comprising a first circular track ( 106 ) for possible bearing of a first threaded tightening element ( 204 ) of a first spacer-leveller device ( 20 ); a second diametrical track ( 109 ), forming a possible bearing surface, with the possibility of longitudinal displacement, for a second tightening element ( 305 ), by way of a wedge, of a second spacer-leveller device ( 30 ); and a lateral surface ( 103 ) with projections ( 104 ) for manually holding the protective device ( 10 ).

First claim

The invention claimed is:

1. A protective device for ceramic pieces, suitable for resting on an upper surface of at least two ceramic pieces and forming a bearing surface of a tightening element of a spacer-leveller device for ceramic pieces, comprising:
a base, a separator of the ceramic pieces and a structure on which said tightening element acts;
a lower bearing surface on the ceramic pieces to be installed,
an upper surface comprising:
at least two first appendages protruding upwardly, in a circular arrangement, which externally delimit a first circular track, configured to allow for rotation, of a first threaded tightening element of a first spacer-leveller device; and at least two diametrically opposed side openings;
at least two second appendages protruding towards the upper area, arranged parallel and delimiting a second diametrical track, aligned with lateral openings and forming a bearing surface, providing longitudinal displacement, of a second tightening element, by way of a wedge, of a second spacer-leveller device and;

a lateral surface provided with at least one pair of projections, diametrically opposed, for manually holding the protective device during threaded tightening of the first spacer-leveller device.

2. The protective device according to claim 1 , wherein the protective device is disk-shaped, defining a circular contour.

3. The protective device according to claim 1 , further comprising a centrally-located first groove parallel to the second track, configured to mount on the first spacer-leveller device, and a second groove, perpendicular to said first groove and configured to mount on the second spacer-leveller device.

4. The protective device according to claim 1 , wherein a first track and the second track comprise polished areas, with a low coefficient of friction, which form bearing and sliding surfaces of the first and second tightening elements respectively.

5. The protective device according to claim 1 , wherein the lateral surface comprises two pairs of projections diametrically opposed and perpendicular two by two.
