Fastening arrangement for a WC flap element

An arrangement comprising a fastening system and a WC flap element,

• said fastening system comprises
• at least one, mounting bolt extending along a center axis with a receiving portion, a stop portion for direct or indirect support on the support surface of a toilet bowl and a threaded portion,
• a hinge support, for mounting the WC flap element, with at least one mounting opening into which the receiving portion of the at least one mounting bolt projects, and
• a non-rotatably mounted mating thread, into which the threaded portion of the mounting bolt engages,
• wherein, in an installed position, the center axis of the at least one mounting bolt extends substantially at a right angle with respect to the horizontal,
• wherein the receiving portion comprises a drive structure,
• wherein the mounting opening is open toward a top, so that the drive structure is accessible and actuatable from the top,
• wherein the mating thread is part of a sliding block, which is mounted in a guide groove with play in at least one direction, and
• wherein said WC flap element is pivotably mounted on the hinge support and the toilet bowl, on which the fastening system is mounted by way of the at least one mounting bolt.

A method for assembling a fastening system, comprising

• at least one mounting bolt extending along a center axis with a receiving portion, a stop portion for direct or indirect support on the support surface of a toilet bowl and a threaded portion,
• a hinge support, for mounting the WC flap element, with at least one mounting opening into which the receiving portion of the at least one mounting bolt projects, and
• a non-rotatably mounted mating thread, into which the threaded portion of the mounting bolt engages,
• wherein, in an installed position, the center axis of the at least one mounting bolt extends substantially at a right angle with respect to the horizontal,
• wherein the receiving portion comprises a drive structure,
• wherein the mounting opening is open toward a top, so that the drive structure is accessible and actuatable from the top,
• wherein the mating thread is part of a sliding block, which is mounted in a guide groove with play in at least one direction,
• wherein in a first step, the at least one mounting bolt is brought into engagement with the mating thread by way of its threaded portion such that the at least one mounting bolt can be displaced in its position relative to the toilet bowl,
• wherein in a second step, the hinge support is brought into connection with the at least one mounting bolt;
• and
• wherein in a third step, the WC flap element is aligned with respect to the toilet bowl;
• and
• wherein in a fourth step, after alignment has taken place, the at least one mounting bolt is tightened by way of the drive structure, and
• wherein, in a fifth, optional step, a cover element covering the hinge support is assembled.
