The ventilation can be carried out at any point in the room, which can also be fixed by spot welding, without the 15 being possible. The base element is filled with insulating material, which is disadvantageous in relation to the wall element 10. Between the floor II and the base element 6, because the actual ventilation system is influenced, a sealing strip / 2 made of elastic material, which is not visible from the outside as well as from the inside, is arranged. The sound that is in the and the smooth wall panels no longer require any openings between the base element 6 and the wall cd, the like. The ventilation cross-sections 20 panel 1 with the one necessary for room ventilation can be determined as required. In addition, if air penetrates, the reflections that take place do not require any structural changes to the tubs due to the sound-absorbing lining 5 of the den, and it is easily possible to add wall panel 1 and by introducing it into the insulating maz.

Claims (8)

Patent claims: 1. Ventilation device for rooms provided with versetebaren partition walls, characterized in that a wall element (1) in its derri adjacent element (6) facing area is provided with a groove-like recess into which the adjacent wall element (6) engages in such a way that for Fresh air supply from neighboring rooms creates a flow channel provided with urnlenkitellen, the sound being attenuated by at least partial lining of the flow channel with sound-absorbing material (5) and / or introduction into the insulating material (10) of a convertible element (6). 2. Ventilation device for rooms provided with movable partitions, characterized in that a wall element (1) and at least one adjacent element (6) are provided in their facing areas with a groove-shaped recess into which an existing refractory material, with passages (13) provided intermediate element (14) engages, ν ihei the groove of one element (6) corresponds to the thickness of the intermediate element (14) and the groove of the other element (1) is considerably wider than the thickness of the? Zwisc ^u enelementes (14) is. so that for the fresh air supply from neighboring rooms a flow terminal provided with original steering points is created, the sound being attenuated by an at least partial lining of the flow channel with sound-absorbing material {Si. 3. Ventilation device according to claim 1 and 2, characterized in that the flow channel for the fresh air is arranged between a wall element (1) and a base element (6). 4. Ventilation device according to claim 1 and 2. dadu ^r ch characterized in that in the known manner of outer wall panels (2) with intermediate insulating material (3) existing partition in the adjacent element (6) facing area at least partially with schalldämmcndem material (5) provided U-profile (4) is used. 5. Ventilation device according to claim 1 and 1. characterized in that on the U-shaped part (7) of the base element (6) in the area of Overlap with the wall panel (1) on both sides a step-like profile (8) attached is. which is closed at the end by a perforated strip (9). 6. Ventilation device according to claim 2, characterized in that the Zwischenelcment (14) on the U-profile (4) of the wall element (1) is attached and engages in the sound-absorbing filling (10) of the Sockelcnientes (6). 7. Ventilation device according to claim 2 and 6, characterized in that the substantially 6s of a U-profile Π) existing base element (6) with the help of on the Zwischenelcment (14) adjacent elastic elements (16) is completed. 8. Ventilation device according to claim 7, characterized in that the elastic elements (16) Steel springs are provided. The invention relates to a ventilation device for rooms with removable partition walls, Movable partitions are known - you have, in particular, the advantage of being able to vary the size of the partitioned off rooms as required. With the known movable partition walls, however, the problem of room ventilation is still present has not been satisfactorily resolved. So it is known, for example, the ceiling elements to be provided with perforated plates and to install cone-like ventilation devices. It is also known to have louvre-like vents or fans in the wall elements to use. However, these known room ventilation devices have the disadvantage that they outside of the Noises caused by the partition walls pass into the room without the To muffle sound. In addition, the known devices are not fire retardant either. The object of the invention is to create a movable partition J. with their Hilie in a simple manner Way, an easily adjustable, low-noise ventilation of the separated room takes place. According to the invention, this object is achieved in two ways. The first solution is that a wall element in its facing the adjacent element Area is provided with a groove-like recess into which the adjacent wall element intervenes in such a way that one with deflection points for the fresh air supply from adjacent rooms provided flow channel emerges, with the sound by at least partially lining the flow channel with sound-absorbing material and or introduction into the insulating material of a wall element is damped. The second approach provides that a wall element and at least one adjacent element are each provided with a groove-shaped recess in their facing areas into which a Intermediate element made of refractory material and provided with passages engages, the groove of one element corresponds to the thickness of the intermediate element and the groove of the other element increases is wider than the thickness of the intermediate element. so that for the fresh air supply from neighboring A flow channel provided with deflection points is created in the premises, whereby the sound passes through a at least partially lining the flow channel with sound-absorbing material is attenuated. With the second solution it is also achieved that the partition also has a fire-retardant effect. According to a preferred embodiment, the Flow channel for the fresh air is arranged between a wall element and a base element. In the known manner consisting of outer wall panels with insulating material in between The partition wall is at least partially in the area facing the adjacent element U-profile provided with sound-absorbing material is used. In the first approach, the U-shaped part of the base metal is in the area of the overlap with the blackboard on both sides a step-like profile attached, which ends through a perforated strip is completed.
