Device for fixing sieve component in floor well - involves floor lining clamped to well by clamp ring which under permanent pressure exerts radially outwards force against floor lining

摘要

To permit the retention of the sieve component in the floor well without it being required to be formed in any particular way, the clamp ring (3) has at least one radially inwardly directed part (4) and the sieve component (6) has at least one hook unit (11) which grips under the clamp ring radially inwardly directed part (4) to hold the sieve component (6) against the clamp ring (3).
