Abstract
Abstract The faces (33) of the plate into which the gully is cast, are extended all around by lattices (40) of glass fiber. These form a compound with the subsequently poured plaster floor so that a tension-proof connection is ensured when the tiles are fastened by an adhesive or mortar. According to a preferred embodiment, the plate may additionally be anchored in the plaster floor by reinforcement wire meshes (41) cast into said plate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
A discharge fitting for a tiled floor, comprising: a sink provided with a headpiece which carries a grate; a plate adapted for receiving said sink and including surfaces directed toward said sink; and a lattice fixedly connected to said plate on all sides thereof for outwardly extending said surfaces of said plate all around, said lattice being placed on a floor so as to form a foundation for tiles to be subsequently attached by means of a suitable compound material, with said lattice being bound in the compound material in order to attain a tension-proof connection between said plate and the floor.
Claim 2
Dependent Claim
102 words
A discharge fitting for a tiled floor, comprising: a sink provided with a headpiece which carries a grate; a plate adapted for receiving said sink and including surfaces directed toward said sink; and a lattice fixedly connected to said plate on all sides thereof for outwardly extending said surfaces of said plate all around, said lattice being placed on a floor so as to form a foundation for tiles to be subsequently attached by means of a suitable compound material, with said lattice being bound in the compound material in order to attain a tension-proof connection between said plate and the floor.
Claim 3
Dependent Claim
16 words
A discharge fitting as defined in claim 1 wherein said lattice is made of glass fibers.
Claim 4
Dependent Claim
27 words
A discharge fitting as defined in claim 1, and further comprising reinforcement wire meshes cast into said plate and extending horizontally below said lattice for anchoring purposes.
Claim 5
Dependent Claim
16 words
