System with toilet seat component and fixing devices as well as toilet seat riser

Abstract

System, comprehensive - a toilet seat component (2) and - exactly two fastening devices (1) for fastening the toilet seat component (2) to a toilet bowl (3) with prepared recesses (4, 5) for fastening the toilet seat component (2), wherein each of the fastening devices (1) comprises a screw (6) with a screw head (7) and with a screw thread (8), a dowel (9) with a neck portion (11), and a sleeve (17) received via the screw thread (8), wherein the screw (6) passes through the dowel (9) and the sleeve (17), so that upon an externally induced rotational movement of the screw (6) relative to the sleeve (17), the sleeve (17) can be displaced in the axial direction along the screw (6), wherein the sleeve (17) has an expanded portion (19), wherein the expanded portion (19) and several movably designed dowel arms (13-16) of the dowel (9) can be brought into mutual contact,so that, depending on the extent of displacement of the sleeve (17) in the direction of the screw head (7) by the rotational movement of the screw (6) in a first direction of rotation of the screw (6), the dowel arms (13-16) can be adjusted outwards to different extents from an initial position of the fastening device (1) applied to the dowel (9), and the dowel arms (13-16) can be adjusted inwards by a displacement of the sleeve (17) in the direction away from the screw head (7) by a rotational movement of the screw (6) in a second direction of rotation of the screw (6), characterized in that the sleeve (17) has stop means (28) matched to a dowel arm (13-16), which, when the screw (6) rotates relative to the dowel (9), prevents or limits a joint rotational movement of the screw (6) and the sleeve (17) due to the sleeve (17) being carried along by the screw (6), in that the stop means (28) come into contact with a dowel arm (13-16), , wherein the head of the dowel rests with its underside on the edge around the respective opening in the toilet seat component, wherein exactly two openings are formed in the toilet seat component for exactly two fastening devices.
