  • the support member 21 is in this case moved against the spring force of the tension spring 26 relative to the base plate 22.
  • the bolt 233 of the joint 23 is hereby displaced in the oblong holes 212 on the side of the first leg 210 of the support element 21.
  • the support member 21 moves as long as in the direction of the center of the housing 10 until the mounting hole M is overcome. Afterwards springs, as in FIG. 14 shown, the support member 21 back to the starting position by means of the tension spring 26. The support member 21 is supported on the top of the ceiling D from. In this state, the support member 21 is thus in the Vorfixier ein and the ventilation device 1 is thus prefixed. The adjusting screw 22 is then tightened to each of the four fastening devices 2. This turns, as in the FIGS. 15 and 16 shown, the support member 21 via the bolt 233 and the slot guide 212 down.
  • the bolt 233 protrudes through the slots 212 and the slots 212 are inclined, by turning the screw 22, the bolt 233 is moved downward, thus moving the free end of the second leg 211 of the support member 21 down.
  • the free end of the second leg 211 presses on the top of the ceiling D and thereby raises the housing 10 until the projection 13 of the housing 10 rests against the underside of the ceiling D.
  • the ventilation device 1 is stretched against the ceiling D, that is firmly clamped to this.
  • the screw 22 is released from the inside again until the pin 233 reaches the upper stop 234 on the screw 22.
  • These steps are in the FIGS. 17 and 18 shown.
  • the user can support the housing 10 from below and lift slightly and operate from the inside the handle 27 of the support member 21.
  • the noses of the handle 27, which are in FIG. 19 are shown, pushed in the direction of the screw 22 away.
  • the support member 21 against the Retracted spring force and the support member 21 no longer protrudes beyond the edge of the housing 10 also.
  • the housing 10 can then be removed from the mounting opening M.
  • the present invention thus provides a simplified ceiling mounting of ventilation devices, in particular so-called integrated ceiling ventilation.
  • the installation at the user is associated with the least possible effort and low burden.
  • the fastening device according to the invention which can also be referred to as a suspension, ensures a secure and firm hold of the ventilation device, which is also referred to as a device, in the ceiling.
  • a facilitated disassembly of the ventilation device is made possible from the ceiling.
  • the present invention allows a mounting of the ventilation device at different wall thicknesses.
  • the device can be mounted in a ceiling that has a wall thickness of up to 50 mm.
  • the assembly according to the invention is considerably simplified. Compared to devices that protrude latch hook, disassembly is facilitated in the present invention.
  • the present invention has a number of advantages.
  • no additional scaffolding is necessary, which would have to be installed in the ceiling before.
  • the ventilation device can be easily connected to the fastening device.
  • the device can only be prefixed in a section of the ceiling. This makes the assembly easier to carry out, since the device does not have to be kept permanently.
  • the ventilation device can be installed with a wall thickness of the ceiling of 16 mm to 55 mm. The assembly is faster. In addition, a uniform tension in the mounting hole is possible. Finally, a secure and firm fit in the ceiling is made possible.
  • the present invention allows the integrated ceiling vent to be pre-fixed in the ceiling first, and the user or after-sales service can now freely hang the device without additional load.
  • the device does not have to be kept constantly by a second person.
  • a device can be mounted even with a wall thickness between 16-55 mm.
  • Another advantage is also that a customer who already has a suspended ceiling, the installation can also make blind, since the installation is always done from below.
  • the disassembly is facilitated here, since only the screw has to be rotated and the device thereby moves down. It remains prefixed until, for example, a fixing screw or a handle is moved again.
