DETAILED DESCRIPTION OF THE INVENTION

[0031] A leveling shim 1 (FIGS. 1-5) comprises a plastic plate 2 having a rectangular-shaped plan view with rounded corners and a height of a few millimeters, for example of 2 mm.

[0032] The leveling shim 1 provides a plurality of fastening through holes 3 and coupling means comprising a plurality of coupling through holes 4 and a plurality of flexible coupling means 5.

[0033] The flexible coupling means 5 comprise a flexible arm 51 comprising a first end 52 constrained to the plate 2 and a second end 53 which is free (FIG. 9).

[0034] Said second end 53 provides a coupling pin 54.

[0035] The flexible arm 51 is able to bend into through cavities 6 of the plate 2.

[0036] The fastening through holes 3 are preferably flared and are able to interact with screws.

[0037] FIG. 6 shows a leveling assembly 7 mounted on a base 8 and formed by three stacked leveling shims 1.

[0038] Operatively, the coupling of two leveling shims 1 occurs by superimposition, so that the coupling pins 54 of at least one leveling shim 1 are coupled, by interference, to the coupling through holes 4 of another leveling shim 1.

[0039] FIGS. 3, 4 show the coupling pins 54 of a single leveling shim 1 which protrude with respect to the height of the plate 2.

[0040] In case of coupling with another leveling shim 1, the coupling pin 54 remains completely inside the coupling through hole 4 of the overlying leveling shim 1 (FIG. 9).

[0041] In FIG. 8 the leveling assembly 7 is fastened to the base 8 by means of screws.

[0042] The base 8 may be wedge-shaped.

[0043] The leveling shim 1 in contact with the base 8 (FIG. 9) shows the flexible arm 51 bent so that the coupling pin 54 is entirely contained in the through cavity 6 thereof.

[0044] Advantageously, the flexible coupling means 5 do not increase the overall height of the leveling assembly 7, i.e. they disappear into the through cavities 6 and into the coupling through holes 4 in case of coupling.

[0045] In case two leveling shims 1 are coupled to the coupling pins 54 protruding towards each other, each coupling pin 54 is coupled to a respective coupling through hole 4 since the arrangement of the coupling through holes 4 and of the flexible coupling means 5 is specular with respect to a median line M shown in FIG. 2.

[0046] The base 8 may provide coupling holes able to couple to the coupling pins 54 of a leveling shim 1, thus making the use of screws which, in general, are not necessary in making the leveling assembly 7, unnecessary.

[0047] Advantageously, the coupling of two leveling shims 1 is easy, immediate and, above all, it defines a leveling assembly 7 the dimension of which is given by the sum of the overall dimension of the plates 2 of the two leveling shims 1.

[0048] The flexible coupling means 5 do not increase the dimension of the leveling assembly 7 and also adapt to the application of the leveling assembly 7 to a base 8.

[0049] The cavities 6 further lighten the leveling shim 1 giving full housing to the flexible coupling means 5.

[0050] The leveling shim 1 object of the present invention may also be used in sectors other than building, for example, to interrupt the unpleasant rocking of tables, chairs, furniture, sofas, armchairs and other similar products which rest on a surface which often is non-regular.

[0051] Preferably, the leveling shim 1 is provided with median grooves 10 (FIGS. 1 and 2) able to facilitate fragmentation in smaller portions comprising flexible coupling means 5, at least one coupling through hole 4, and preferably at least one fastening through hole 3.
