6. The combination according to claim 3, wherein a depending wall is arranged on the free edge of the flange and wherein the edge zone of the watertight, flexible membrane is adhered to the depending wall.

7. The combination according to claim 1, wherein an adhesive layer is arranged between the seal and the underside of the drain.

8. The combination according to claim 1, wherein the seal is a watertight, flexible membrane, such as a tile membrane, which seal comprises at least a fixing surface with at least two straight edges lying at an acute angle, preferably an angle of 90 degrees, and surfaces standing upright along the at least two straight edges.

9. The combination according to claim 8, wherein a stepped part is arranged in the upright surfaces.

10. The combination according to claim 1, wherein the drain is a flat plate, which flat plate is provided with an opening which forms the inflow opening on the upper side and forms an outlet opening on the underside of the flat plate.

11. The combination according to claim 1, further comprising a second watertight, flexible membrane which is arranged on the upper side of the drain, wherein the second watertight, flexible membrane comprises an opening which corresponds with the inflow opening of the drain.

[0041] FIG. 3 shows a third embodiment of a device according to the invention in perspective view.

[0042] FIG. 4 shows a cross-sectional view of the embodiment according to FIG. 1.

[0043] FIGS. 5 and 6 show a fourth embodiment of a combination according to the invention.

DESCRIPTION OF THE INVENTION

[0044] FIG. 1 shows a device 1 and a collecting tray 2 according to the invention. Device 1 has a fixing plate 3 with four straight edges 4. Arranged in the fixing plate 3 is a fastening opening 5 through which a threaded end 6 protrudes in installed state, onto which threaded end a nut 7 is tightened.

[0045] Threaded end 6 is arranged on the underside 8 of the bottom of collecting tray 2. An upright wall 9 is provided along the peripheral edge of this bottom 8 and an outflow 10 is provided in bottom 8.

[0046] A preformed membrane 11, 12 is arranged on fixing plate 3 along two straight edges 4. This preformed membrane 11, 12 is embodied with an edge zone 12, which is adhered to fixing plate 3, and an upright part 11.

[0047] FIG. 2 shows a second embodiment of a collecting tray 20 and a device 21 according to the invention. Collecting tray 20 has a bottom 22 with a wall 23 standing upright along the periphery and a peripheral flange 24 which is arranged on the upper edge and is parallel to bottom 22.

[0048] Arranged on the underside of bottom 22 is a threaded end 25 which protrudes through a fastening opening 26 in a fixing plate 27 of device 21. A nut 28 is tightened onto threaded end 25 in order to fixedly clamp fixing plate 27 against bottom 23.

[0049] Arranged along two edges 29, lying at right angles, of fixing plate 27 are upright walls 30 on which a horizontal flange 31 is arranged. A preformed membrane 32 with an L-shaped cross-section is adhered to this flange 31.

[0050] FIG. 3 shows a third embodiment of a device 40 according to the invention. Device 40 has a fixing plate 41 with a fastening opening 42. Provided along two straight edges of the fixing plate 41 are depending walls 43 on which a strip of watertight, flexible membrane 44 is arranged. The upper side of this membrane 44 lies clear and can be adhered to a wall of a space.

[0051] FIG. 4 shows the embodiment 1, 2 according to FIG. 1 in installed state. An adhesive layer 13, such as a sealant, is arranged between bottom 8 of collecting tray 2 and fixing plate 3 of device 2. Fixing plate 3 is clamped firmly against sealant 13 and bottom 8 by means of the nut 7, whereby a good and reliable fixing of the watertight, flexible membrane 11, 12 is obtained.

[0052] FIG. 5 shows a fourth embodiment 50 of a combination according to the invention. Combination 50 has a drain (partially shown) with a bottom 51, upright wall 52 along the periphery of bottom 51 and a horizontal peripheral flange 53.

[0053] Arranged against the underside of bottom 51 is a seal with a fixing surface 54 with upright surfaces 55 which are arranged along two straight edges and in which a stepped part is arranged.

[0054] A second flexible, watertight membrane 56 is arranged against the upper side of drain 51, 52, 53. Provided in this membrane 56 is an opening 57 which corresponds with the inflow opening surrounded by the upright wall 52 of drain 51, 52, 53.

[0055] FIG. 6 shows the combination 50 installed against two walls 58. Seal 54, 55 is arranged against the underside of bottom 51 of the drain and the second watertight, flexible membrane 56 is fixed to the horizontal flange 53.

[0056] A corner 59 has been removed from this second membrane 56 so that the longitudinal edges of membrane 56 can be folded and can be arranged, overlapping the upright surfaces 55, against walls 58.
