  • a tile system in a room or in another accommodation may serve a variety of purposes.
  • One purpose of having a tile system such as a suspended ceiling system may be to conceal an underside of a space, such as another room, which is located above the room.
  • Another purpose may be to provide improved noise absorption and/or noise attenuation in and outside of the room.
  • Tile systems for rooms or similar typically also include sound absorbing baffles in form of generally vertically suspended tiles.
  • a suspended ceiling consists of a plurality of ceiling tiles which may be suspended from the main ceiling or structural ceiling.
  • the ceiling tiles may be suspended from the main ceiling using wires or lines which are attached to the main ceiling and to the ceiling tiles such that the ceiling tiles become suspended below the main ceiling, thereby forming a suspended ceiling.
  • the ceiling tiles may also be suspended using a profile framework or similar.
  • baffles may be suspended using various kinds of elements.
  • the ceiling tiles may be provided with a number of fasteners which in turn may be connected to the wires or lines used to suspend the ceiling tiles.

  • baffles are commonly provided with a number of fasteners.
  • the fasteners include some form of eye or hook which is used to connect to wires, lines or similar used to suspend the tiles.
  • the fasteners must provide a reliable connection to the tiles and at the same time offer a simple connection to the tiles.
  • the fasteners are commonly attached to the tiles at the construction site prior to installing the tiles. This means that a plurality of fasteners typically has to be connected or fixed to each tile. This work is time-consuming. Also, the length of the wires or lines used must be correctly adjusted to suspend the tiles. This work is time-consuming. The time-consuming work implies high costs due to e.g. personnel expenses.

  • the anchor element may be pre-mounted or pre-attached to the absorber tile element at hand, with a significantly reduced risk of damaging the tile during handling, transport, storage etc. This is particularly true when a plurality of tiles is stored and stacked. This because the anchor element is recessed in the respective tiles, meaning that there are no significantly protruding portions which are otherwise prone to damaging the tile itself or other tiles e.g. being stacked on top of the tile concerned. Also, the height of a stack of tiles may be significantly reduced since the tiles may be stacked directly on each other since there are no protruding portions of the anchor elements or portions protruding to a limited extent.

  • the wire may not be defected, resulting in that any misalignment related to loading the wire may be counteracted.
  • a further absorber tile element or another object may be suspended below the absorber tile element while in principle not affecting the anchor element.
  • the head portion and the threaded portion may partially overlap in a direction along a central axis of the anchor element, which is advantageous in that the anchor element may be tailored to suit specific needs or desires.
  • the thread of the threaded portion may continue onto the head portion enabling more thread to engage the absorber tile element, hence making the coupling between the anchor element and the absorber tile element stronger.
