DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(11) In view of the aforementioned figures and, in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

(12) As shown in FIG. 1, an embodiment of a waterproofing assembly for a built-in shower drain comprises an upper grate 5 and a drain body 2 with a mouth 8, the drain body 2 located in the lower part of the assembly which is housed in the drainage hole and which allows for the exit of water coming from the shower tray when it is being used to a wastewater treatment plant.

(13) Moreover, the assembly also includes a clamping ring 3 arranged between the upper grate and the drain body, the shape of the body being essentially discoidal. This clamping ring 3 is coupled by means of a threaded section 30 to a threaded section 50 present on an extension which extends below the upper grate 5, as may be seen more clearly in FIGS. 1 and 10.

(14) With the aim of adapting the width of the built-in shower tray structure, an adaptive device 1 is provided, arranged between the upper grate and the drain body, which comprises a body having a very small thickness made of a waterproofing material which is essentially made up of an upper section 1a and a lower section 1b with a through hole in parallel arrangement at different levels, the upper 1a and lower 1b sections joined together by means of a deformable intermediate section 1c which is capable of folding by means of a plurality of fold lines which run diametrically through the intermediate section 1c. These fold lines 7 allow the height of the adaptive device 1 to be modified. It is noteworthy that the through hole on the lower section 1b is made once the device is mounted in the built-in shower installation, such that the dimensions of the hole are adapted to the dimensions of the drainage hole on the built-in shower.

(15) FIGS. 6a to 6c show different configurations which the intermediate section 1c may adopt, wherein in FIG. 6c, fold lines 13 extend from the lower edge of the intermediate section 1c in a curved trajectory in the direction of the upper edge of said intermediate section 1c.

(16) Furthermore, the assembly includes a template piece 14 envisaged for being arranged on a clamping ring 3, which comprises a body of a rigid material which has an upper surface 14a and a lower surface 14b with a central through hole 14d, the surfaces being separable from one another, the upper 14a and lower 14b surfaces joined together by means of an intermediate section 14c, the lower surface 14b having a plurality of protuberances 16, 17, in which at least one of the protuberances has a through hole. The clamping ring 3 includes a plurality of holes 3b radially distributed, envisaged to allow the passage of screw elements 4.

(17) It is noteworthy that the adaptive device 1 and the template piece are axially aligned with respect to the drain body 2 and the clamping ring 3.

(18) The body of the adaptive device 1 is made of a waterproofing laminar material and has a generally circular plan.

(19) Returning to the template piece 14, the protuberances 16, 17 of the template piece 14 are arranged in two assemblies, radially distributed with respect to the central through hole.

(20) Moreover, the template piece 14 includes a pair of perforated pre-cut lines 18, 19, the pre-cut line 18 arranged in the peripheral area of the lower section while the pre-cut line 19 is located on the central part of the lower surface 14b of the template 14.

(21) Additionally, the intermediate section 14b of the template piece 14 includes a marking line 15, which is shown in FIG. 2.

(22) Advantageously, each of the protuberances 16 of the first set of protuberances has a circular plan and includes a through hole, through which screw elements 4 may pass, while the protuberances 17 have a generally oblong form.

(23) As can be seen with greater clarity in FIGS. 8 and 9, the lower surface 14b of the template piece 14 has a circular plan.

(24) As can be seen in FIG. 9, the upper surface of the template piece 14 has an essentially quadrangular plan.

(25) As can be seen in FIG. 10, the clamping ring is coupled to the template piece and the drain body by means of screw elements which pass through protuberances of the template piece.

(26) The details, shapes, dimensions and other accessory elements used to manufacture the device and assembly of the invention may be suitably substituted for others which do not diverge from the scope defined by the claims included below.
