DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

(7) 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.

(8) Thus, as seen in FIGS. 1 to 4, a possible preferred embodiment of the device for adapting a flapper of a flush valve of a toilet tank to a valve base with a lateral overflow pipe essentially comprises the following elements: An element (1) for fastening to the overflow pipe, which has a ring shape and which comprises a pair of recesses (10) able to house lugs (4) arranged in the overflow pipe (3). The recesses (10) of the fastening element (1) comprise a divergent mouth (12), in order to enable the automatic positioning of the lug in the recess, and it further comprises a bulge (25) in the inner end thereof which defines a housing (11) of the lugs (4) arranged in the overflow pipe (3). In order for the lug to be able to partially deform the recess before being inserted into the housing (11), the fastening element is made of an elastic material. The fastening element (1) further comprises a pair of lugs (13) arranged in opposite positions in a section of said fastening element (1). A flapper (2) made up of a flapper body (20) and a pair of arms (21) arranged in the upper portion of said flapper body (20), the end of each arm comprising a housing (22) able to house the lugs (13) of the fastening part (1), whereon the flapper (2) is articulated when a chain joined to the upper portion of the flapper body (20) is pulled.

(9) A supplementary element (30) can be added which is arranged between the fastening element (1) and the overflow pipe (3) and adapts the inner diameter of the fastening element (1) to the outer diameter of the overflow pipe (3).
