Drain device with an adjustable support for a drain cover

A floor panel (10) comprising a drain device (100) for installation in an opening (12) of a floor panel (10), the drain device (100) comprising:

• an upper inlet opening (13), through which waste water can inter the drain device (100),
• a cover (14) delimiting the upper inlet opening (13), which is supported by an extension element (15), and
• an adjusting device (150) that can be pre-assembled in s floor area in which the drain device (100) is installed, wherein the adjusting device (150) can be connected in a fluidic manner to a drain pipe (16), so that waste water which has passed through the inlet opening (13) can enter the drain pipe (16),
• wherein the adjusting device (150) comprises the following components:
• a receptacle (40) for installation in the floor panel (10) with a bearing surface (21) and an inner contour (22) which has an inner diameter (D2),
• a retainer (25) insertable into the receptacle (40) for the extension element (15), wherein the retainer (25) has an outer contour (26), an upper side (27) and a lower side (28), and wherein the outer contour (26) has an outer diameter (D1) which is smaller than said inner diameter (D2) of the receptacle (40), so that the retainer (25) inserted into the receptacle (40) is movable in a horizontal direction (RH) within a horizontal range of play (SH) in the pre-assembled state (Z1), and
• a fixing element (30) which can be attached to the receptacle (40) and which has an upper side (31) and a lower side (32) and which allows the retainer (25) to be moved vertically (RV) relative to the fixing element (30) in the pre-assembled state (Z1) while allowing a play (SV),
• so that in the pre-assembled state (Z1) of the receptacle (40), retainer (25) and fixing element (30), the retainer (25) is freely movable in the receptacle (40) within a vertical play (SV) and a horizontal play (SH),
• wherein the upper side (27) of the retainer (25) has a recess (35) and the fixing element (30) has a projection (36) that can be inserted into the recess (35) and which, in the pre-assembled state (Z1), is arranged inside the recess (35) and limits the play (SH) of the retainer (25) relative to the fixing element (30) in the horizontal direction (RH).
