- control surfaces are formed according to the invention in link slots or elongated holes or longitudinal slots and the driver elements consist of them engaging pins or pins.
- a pin forming the first driver element is provided with a transverse seat for a pin forming the second driver element.
- a ventilation device can be further optimized in that the shut-off element is assigned an auxiliary adjusting device at its end facing away from the adjusting device, which consists of a pin fixed to the housing and a link plate connected to the shut-off element, the link plate corresponding to the combined length - And transverse displacement of the shut-off element inclined inclined slot, which can be brought into and out of engagement with the pin solely by the pivoting movement of the shut-off element.
- the shut-off element is assigned an auxiliary adjusting device at its end facing away from the adjusting device, which consists of a pin fixed to the housing and a link plate connected to the shut-off element, the link plate corresponding to the combined length - And transverse displacement of the shut-off element inclined inclined slot, which can be brought into and out of engagement with the pin solely by the pivoting movement of the shut-off element.
- a particularly safe control of the shut-off device in its closed position can be achieved by assigning bracket pieces, which are designed as angled legs and are designed as angled lower abutment of the shut-off device in the extruded or extruded profile of the housing and are engaged with one edge notch on the angled leg that the front bracket leg forms with its upper end a support for the lower longitudinal edge of the shut-off device, and that the rear bracket leg is provided on a longitudinal section projecting above the support bracket with a run-up slope for a transverse edge of the edge notch on the angle leg of the shut-off device, which is one of the combined length - And transverse adjustment of the shut-off element has a corresponding inclination in the longitudinal direction of the housing.
- bracket pieces are detachably fastened, for example by screws, in the housing and that they are formed from metal or plastic molded parts which have a configuration symmetrical to a transverse plane.
- the latter design measures make it possible to use one and the same bracket pieces, regardless of whether the actuating device is now provided on the right or left end of the ventilation device.

- the inner air openings 20 are provided in the manner of lattice perforations in the extruded profile 6, while the outer air passage openings 21 are in the extruded profile 7 as perforated lattices.
- the air passage openings 20 are assigned an essentially strip-shaped shut-off element 22, which moves from a locked closed position (FIGS. 1, 4 and 11) to an unlocked intermediate position (FIGS. 2 and 7) into the open position (Fig. 10) is adjustable.
- the strip-shaped shut-off element 22 is held and guided both longitudinally and transversely displaceably parallel to its closure plane, while the movement from the intermediate position into the open position - and vice versa - by swiveling adjustment of the shut-off element 22 takes place.
- shut-off element 22 For the purpose of its displacement from the locked closed position into the intermediate position and vice versa, the shut-off element 22 is guided in a floating manner in its plane, while its pivoting movement takes place from the intermediate position into the open position about a given axis.
- the entire movement sequence is controlled with the aid of a special adjusting device 23, which is assigned to one of the two end pieces 8 and 9, for example the end piece 8.
- the two longitudinal edges 24 and 25 of the shut-off element 22 each have a lock over their entire length for locking its closed position in the housing 2 extending piece bearing 26 and an abutment 27 assigned.
- the piece bearing 26 is formed by a bead formed on the extrusion profile 4, with which a wedge surface 28 comes into active connection, which adjoins the longitudinal edge 24 of the shut-off element 22.
- the shut-off 22 is pressed against the back of the extruded profile 6 in its closed position, and locked between the latter and the support bearing 26 (Fig. 4 and 11), while it covers the inner air passage openings 20 in the extruded profile 6.
- the shut-off element 22 interacts via an angle leg 29 projecting from the rear of it, in such a way that the angle leg 29 aligns the shut-off element 22 with minimal play against the rear side of the extruded profile 6.
- the abutment 27 is formed by a support web which is integrally formed on the extrusion profile 3 of the housing 2, as can be clearly seen in FIGS. 4, 7, 10 and 11.
- the shut-off element 22 is clamped on the one hand in an engagement gap 30 between the extrusion profile 4 and the extruded profile 6, while on the other hand it comes to rest on the support web of the extrusion profile 3 serving as an abutment 27 via the angle leg 29 and from there is pressed against the back of the extruded profile 6.
- the actuating device 23 for the shut-off element 22 works with a two-armed lever 31, which engages via a bearing bush 32 with a bearing mandrel 33, which is provided on the inside of the end piece 8.
- One lever arm 34 protrudes forward through a cutout 35 of the end piece 8 and can be used as a swivel arm for actuating the adjusting device 23.
- the other lever arm 36 of the two-armed lever 31 is oriented at an obtuse angle to the lever arm 34 and projects into the end piece 8 such that its outer longitudinal surface is in the region of the cutout 35 comes to lie flush with the inner surface of the end piece 8 when the shut-off element 22 assumes its locked closed position within the housing 2, as shown in FIGS. 4 and 11 of the drawing.
- the lever arm 36 of the two-armed lever 31 is provided with a molded slot slot 37, which has an inclined position relative to the longitudinal direction of the lever arm 36, which runs parallel or at an acute angle to the lever arm 34.
- the link slot 37 is provided in the lever arm 36 so that it lies over its entire length outside the bearing bush 32 or the associated bearing mandrel 33.
- the bearing pin 33 has a slot slot 38, the inner end of which is trough-shaped and aligned with the axis of the bearing pin 33, while it is open towards the circumference of the bearing pin 33.
- the link slot 38 preferably has a vertical alignment position.
- the link slot 37 in the lever arm 36 is provided such that its upper or most distant end from the axis of the bearing bush 32 lies on a vertical plane above the link slot 38 when the shut-off element 22 assumes its locked closed position in the housing 4 (see FIG. 4).
- the two-armed lever is pivoted from its position corresponding to FIGS. 4 and 11 by a certain angle, for example by 20 °, into a position in which the lower, the common longitudinal axis of the bearing bush 32 and bearing pin 33 the closer end of the slotted slot 37 comes to lie on a vertical plane above the slotted slot 38 (see FIG. 7).
- the actuating device 23 also has a driver 39 which has a tongue 41 which projects from the end face of a plate 40 and which engages with an engagement channel 42 of the shut-off element 22 in jamming clutch engagement can be brought.
- a driver 39 which has a tongue 41 which projects from the end face of a plate 40 and which engages with an engagement channel 42 of the shut-off element 22 in jamming clutch engagement can be brought.
- On the back are from the plate 40 of the driver 39 from two pins 43 and 44, which in one predetermined distance lie one above the other and are aligned parallel to each other (see. Fig. 1 and 2).
- the pin 43 protrudes as a bearing and guide pin into the link slot 38 on the bearing mandrel 33, while the pin 44 engages with the link slot 37, which is located in the lever arm 36 of the two-armed lever 31.
- a pin 46 is brought into engagement, which protrudes into a link slot 47, which is also located in the lever arm 36 of the two-armed lever 31 and opens into the link slot 37 on the inside.
- the link slot 47 is provided with an oblique position against the pivoting plane of the two-armed lever 31, as can be seen in FIGS. 5 and 6 and 8 and 9 of the drawing.
- the link slot 37 in the lever arm 36 of the two-armed lever 31 interacts with the pin 44 of the driver 39 serving as a driving element as a control surface, while the link slot 47 also acts as a control surface on the pin 46 directed transversely to the pin 44.
- the pin 46 has such a length that its free end in any case projects beyond the free end of the lever arm 36 to a certain extent, which can be seen in FIGS. 7 and 10 of the drawing.
- the pin 46 can be forcibly moved further out of the free end of the lever arm 36 in the direction of its longitudinal axis, as can be seen in FIG. 4 of the drawing. This takes place through the interaction of the pin 44 with the link slot 37.
- the free end of the pin 46 is assigned in the end piece 8 concentrically around the longitudinal axis of the bearing mandrel 33 a radially-axially offset shoulder 47 as a support surface which extends over an angular arc, which relative to almost the entire possible pivot angle of the lever arm 36 End piece 8 corresponds.
- the support surfaces of the radially-axially offset shoulder 48 run out into a gap 49 which extends parallel to the closing plane of the shut-off element 22 in the housing 2.
- This gap 49 has a profile height that can accommodate the entire free length of the pin 46 in its extended position (see FIG. 4).
- the pin 46 comes out of the gap 49 in such a way that its free end is adjacent to the radially-axially offset shoulder 48 (FIGS. 7 and 8) .
- the free end of the pin 46 comes in front of the radial and axial support surfaces of the shoulder 48 and is thereby forced to follow the arcuate shape of this shoulder 48.
- the shut-off element 22 can be shifted about a fixed swivel axis from the position according to FIG. 7 to the position according to FIG. 10, the position according to FIG. 10 corresponding to the swivel open position.
- the pivot axis for the shut-off device 22 is aligned in this case with the Longitudinal axis of the bearing mandrel 33 and the pin 43 of the driver 39 supported at the lower trough-like end by its link slot 38.
- shut-off element 22 at each of its ends still cooperates with guide surfaces 50 which are located on each of the end pieces 8 and 9 and concentrically to the longitudinal axis of the bearing mandrel 33 or to the bearing recess for the pin 43 of the driver 39, which is formed at the lower end of the link slot 38.
- guide surfaces 50 each end at the engagement gap 30 for the longitudinal edge 24 of the shut-off element 22, as can be clearly seen from FIGS. 4, 7 and 10 of the drawing.
- shut-off element 22 is assigned an auxiliary adjusting device 51 at its end facing away from the adjusting device 23, said auxiliary adjusting device 51 consisting of a pin 52 fixed to the housing and a link plate 53 connected to the shut-off element 22 .
- the link plate 53 is seated on the outside on the plate 54 of a driver 55, which is coupled to the engagement channel 42 of the shut-off element 22 in the same way as the driver 39 via a tongue 56 formed on the rear of the plate 54.
- the driver 55 also carries a pin 57, which has practically the same arrangement and task as the pin 43 of the driver 39. It engages in the link slot 38 of the bearing mandrel 33, which is also on the end piece 9 located.
- the link plate 53 of the driver 55 contains an inclined slot 58 which runs inclined in accordance with the combined longitudinal and transverse displacement of the shut-off element 22 and which can cooperate with the pin 52 of the auxiliary adjusting device 51 fixed to the housing.
- oblique slot 58 and pin 52 of the auxiliary adjusting device 51 are disengaged. Only when the position according to FIG. 7 is reached does the engagement connection come about, specifically in the relative position of the pin 52 and the oblique slot 58 relative to one another, as can be seen in FIG. 2 of the drawing. If the actuating device 23 is moved 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 is simultaneously displaced from the position according to FIG. 2 into the position 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.
- These support springs 59 are, for example, anchored to the web of the extrusion profile 3 serving as an abutment 27 and anchored and cooperate with the angle leg 29 of the shut-off element 22 such that they engage its upper longitudinal edge 24 and the wedge surface 28 in the engagement gap 30 between the Support extrusion 6 and support bearing 26.
- the support springs 59 can also deflect within the housing 2 in accordance with the displacement movement of the shut-off element 22.
- shut-off element 22 in its locked closed position provides a relatively good seal of the ventilation device 1 against air passage.
- unlocked closed position of the same FIGS. 2 and 7
- a minimal ventilation gap can already be cleared.
- the largest air passage cross-section however, only arises in the open position of the shut-off element 22 shown in FIG. 10.
- the outer air passage openings 21 in the extruded profile 7 are located lower than the inner air passage openings 20 in the extruded profile 6 and that the direct air path between the air passage openings 20 and 21 is shielded by the shut-off device 22, as shown in Fig. 10 of the drawing.
- the shut-off element 22 defines a labyrinth-like curved air flow path within the chamber 19 of the housing 2 and at the same time forms a view-through protection from the air passage openings 21 to the air passage openings 20.
- a special training advantage of a ventilation device 1 of the type described above and shown in the drawing also lies in the fact that a particularly simple adaptation to different installation lengths can be achieved. This is possible in that the two end pieces 8 and 9, which are designed in mirror image to one another, can be coupled to the extrusion profiles 3, 4 and the extruded profiles 5, 6, 7 via the simple plug-in collar profiles 15, 16, 17, 18.
- 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 produced 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 with one another as desired. It then only has to be ensured that on the one hand the components belonging to the adjusting device 23 and on the other hand the components belonging to the auxiliary adjusting device 51 are given a symmetrical design to a certain reference plane, which allows any choice of the installation side (right or left).
- the bracket piece 60 has the configuration, which can be clearly seen in particular from FIGS. 14 and 15, with a front, short bracket leg 62 and a rear, long bracket leg 63.
- the free end of the front bracket leg 62 forms a support pad 64 with which the lower longitudinal edge 25 of the shut-off element 22 can come into active connection during the swiveling-closing movement, as is shown in FIG. 12 on the one hand in broken lines and on the other hand in full lines.
- the rear stirrup leg 63 has a greater length than the front stirrup leg 62, so that it projects upward above the support pad 64 thereof.
- 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 produced 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 constant support on the transverse edges 68 of the bracket piece 60, while the shut-off element 22 in the housing 2 carries out a pivoting displacement, which is indicated on the one hand by solid lines and on the other hand by dashed lines. Over this swivel range, the shut-off device 22 is therefore secured against longitudinal displacement in the housing 2 by means of the bracket pieces 60.
- the angle leg 29 with its notch 66 reaches the region of the lower end of the run-up slope 65.
- the further actuation of the adjusting device 23 then results in a longitudinal displacement of the shut-off element 22 , the right transverse edge 67 of the notch 66 sliding along the run-up slope 65.
- a transverse movement is thus also derived from the longitudinal displacement of the shut-off element 22 via the run-up slopes 65 at the same time. This transverse movement then forces the shut-off element into the locking position, as can be seen in FIG. 4 of the drawing.
- the bracket pieces 60 thus ensure that the shut-off element 22 is also inevitably and safely brought into its locking position (see FIG. 4) even in areas which are at a greater or lesser distance from the adjusting device 23.
- the stirrup pieces 60 can be molded parts Manufacture metal or plastic and are preferably designed symmetrically to a transverse plane 69-69 so that they can be used in the same design, regardless of whether an adjusting device 23 is assigned to the left or the right end of the ventilation device 1.
