Only when the position according to FIG. 7 has been reached does the engagement connection come about, specifically in the relative position of the pin 52 and the oblique slot 58, which can be seen from FIG. 2 of the drawing. If the actuating device 23 is now brought from its actuating position according to FIG. 7 into its actuating position according to FIG. 4, then the oblique slot 58 of the auxiliary actuating device 51 on the pin 52 fixed to the housing moves from the position according to FIG. 2 into the position after Fig. 1.
  • actuating device 23 and the auxiliary actuating device 51 in the housing 2 of the ventilation device 1 only cooperate with the ends of the shut-off element 22, it has proven useful to distribute special support springs 59 over the length of the housing 2 between the latter and the lower longitudinal edge 25 of the shut-off element 22 , for example in the form of multi-angled leaf springs, as can be seen in FIG. 11.

  • the cohesion of the housing 2 with a larger length dimension of the ventilation device 1 can be further supported by the fact that transverse webs with a clamp fit can be inserted into the chamber 19 at certain intervals, which can be manufactured as molded plastic parts, but advantageously as stamped parts made of metal.
  • the two end pieces 8 and 9 of the housing 2 receive a mirror image of one another, there is the possibility of interchanging the arrangement of the adjusting device 23 and the auxiliary adjusting device 51 as desired. It then only has to be ensured that, on the one hand, the components belonging to the actuating device 23 and, on the other hand, the components belonging to the auxiliary actuating device 51 are given a symmetrical design for a specific reference plane, which allows any choice of the installation side (right or left).

  • the rear stirrup leg 63 has a greater length than the front stirrup leg 62, so that it protrudes above the support pad 64 upwards.
  • the bracket leg 63 is provided with a ramp 65, as can be seen in FIG. 14.
  • This run-up slope 65 has an inclination position following the longitudinal direction of the housing 2, which is preferably matched as precisely as possible to the combined longitudinal and transverse adjustment of the shut-off member 22 relative to the housing 2 that can be generated with the aid of the adjusting device 23.
  • each bracket piece 60 there is an edge notch 66 on the angle leg 29 of the shut-off element 22, as shown in FIG. 13 of the drawing.
  • the transverse edges 67 of the edge notch 66 have a permanent support system on the transverse edges 68 of the bracket piece 60, while the shut-off element 22 executes a swivel displacement in the housing 2, which is indicated on the one hand by fully solid lines and on the other hand by dashed lines. Over this swivel range, the shut-off element 22 is therefore secured against longitudinal displacement in the housing 2 by means of the bracket pieces 60.
