Seat-connection to toilet bowl

摘要

The bolt (11) fits in the seat and passes through an opening (3) in the top edge (2) of the bowl. The wing-nut (12) screws onto the bolt, and has protrusions formed by spring ribs (42). These are pressed by a clamping component (13) against the bolt. The body (41) of the nut can consist of a closed hollow cylinder, the diameter of the opening (44) in it being greater than the external diameter of the threaded portion of the bolt. The faces (53) of the ribs towards the bolt contain sections of a screw thread matching that of the bolt.
