Definitions

  • the invention relates to a ventilation device in a frame or the like with a flow channel and a slide, which has a leg for releasing or shutting off the flow channel, the slide being at least partially movable back and forth in the flow channel and with a sealing surface provided leg is assigned a stop surface.
  • DE-AS 12 49 489 describes a ventilation device of the type mentioned, which is intended for installation in a window frame, a window sash or in a wall itself.
  • a slide which is movable in the flow channel of the frame is provided, by means of which the flow channel can be released or blocked. If the slide is with. its sealing surface on the associated stop surface, for example on a slotted plate. , the flow channel is blocked. If, on the other hand, the slide is moved away from the slotted plate, the flow channel is released.
  • the invention is therefore based on the object of designing a ventilation device of the type mentioned in such a way that a reliable shut-off is made possible with comparatively little production and cost expenditure.
  • the ventilation device should only have a relatively low flow resistance when the slide is open. oppose an air flow to allow good ventilation.
  • only a small space requirement and in particular a low overall height should be required for the ventilation device.
  • the ventilation device should be highly reliable and operationally reliable and be able to meet the operational requirements.
  • the slider is substantially U-shaped, wherein a second leg with a sealing surface is present in the flow channel, that said second leg extends over a fraction of the height of the flow channel, that a sealing surface is assigned to the sealing surface of the second leg, and that a guide body is preferably arranged on each of the two long sides of the flow channel which has guide surfaces assigned to the slide.
  • the ventilation device according to the invention is characterized by a particularly simple and inexpensive structure and ensures a reliable shutoff of the flow channel. Due to the U-shaped design of the slide, which according to the invention has a second leg, the flow channel can be shut off at two locations spaced apart from one another. In the locked position, an air cushion forms between the two spaced-apart legs of the slide, which acts as an insulating layer between the exterior and the interior. In addition, a labyrinth-like seal is created due to the second leg according to the invention, which has a high flow resistance.
  • the slide can also be produced in a simple manner, especially since no ventilation slots or the like have to be provided in this slide.
  • the embodiment with two legs has proven to be particularly advantageous.
  • an ever better noise reduction and thermal insulation is achieved, whereby, however, similar to a labyrinth seal, the flow resistance is also increased. Therefore, if special emphasis is placed on noise reduction and thermal insulation, the slide and the associated components of the frame can also have three or more legs in the context of this invention.
  • the slide is advantageously arranged such that it to shut off the flow channel in the direction of Exterior space is movable to the interior.
  • the air pressure or the wind pressure acts in the above-mentioned direction, so that even when the wind is strong outside, the slider cannot be actuated involuntarily by the wind, but rather is firmly pressed by the wind pressure with its sealing surface onto the stop surface . Annoying rattling or the like is thus avoided.
  • the slide has a guide part which bears against an inner wall of the flow channel.
  • a seal between the guide part and the inner wall of the flow channel is created in a simple manner and in the blocked position of the slide an inadmissible air flow is prevented in the area mentioned.
  • Slides with sealing surfaces and the stop surfaces advantageously extend substantially over the entire length of the flow channel.
  • the flow channel can thus practically be designed as a comparatively narrow and long slot over a substantial part, for example the width of the window, in order to obtain the necessary flow cross section, with the correspondingly long design of the slide and stop surfaces nevertheless providing a reliable seal or shut-off is guaranteed.
  • an elongated slide can be produced very easily and inexpensively, for example by extrusion.
  • the slider can thus be manufactured as a long profile rail and then cut to size.
  • one leg of the slide extends essentially over the entire height of the flow channel, this leg being moved towards the outside or interior to release it, while the other leg or legs preferably extends over a fraction of the height about two thirds of the height extend.
  • Such an embodiment represents a particularly favorable compromise between low flow resistance and a comparatively good noise reduction between outside and inside.
  • At least one stop surface is advantageously arranged on a facing grille.
  • a veneer grille generally has strips or panels or the like in order to protect the flow channel, at least against coarse dirt, on the one hand, and to obtain a favorable visual impression on the other hand. If the one abutment surface is now arranged on such a veneer grille that is present anyway, a special component for the abutment surface can advantageously be omitted.
  • the abutment surface on said facing grille extends over a fraction of the overall height, and preferably about a third of the overall height.
  • a weather protection strip is advantageously provided above the flow channel and preferably on the outside of the frame.
  • this weather protection strip By means of this weather protection strip, the slide to be moved into the outside space, including the leg present there, is protected. Furthermore, such a weather protection strip prevents the ingress of rain and coarse dirt into the flow channel.
  • a guide body is arranged on each of the two long sides of the flow channel, which has guide surfaces assigned to the slide.
  • Such a guide body can be produced at low cost and ensures that the slide is guided properly. There is no need to mention that, in the case of a relatively long flow channel, several such guide bodies can also be provided.
  • the guide part of the slide contains grooves or slots into which preferably bolts arranged in the guide body engage or vice versa.
  • Grooves or slots can be made very easily in the slider or in the guide body and associated bolts can be arranged in the guide body or in the slider without any special manufacturing outlay. A simple and reliable guidance is thus obtained, and tilting or jamming of the slide can practically not occur.
  • the said grooves or slots are advantageously arranged obliquely or at an angle to the direction of flow, and they may have a predetermined curve shape.
  • the movement according to the invention in the flow direction is also accompanied by a further movement transverse to the same.
  • the opening or closing process of the slide can be influenced in a simple manner.
  • a relatively long movement path can first be predetermined for the slide in order to obtain a favorable force-displacement ratio.
  • the guide body has a shoulder, the height of which corresponds approximately to the height of one leg of the slide.
  • the slide is thus guided on the one hand on the end face of said leg and on the other hand also on its guide part by means of said guide body. It can be seen that the functional reliability is improved by this multiple guidance.
  • the guide bodies are expediently connected to one another with a connecting element in order to enable a quick and secure installation in the frame or the flow channel.
  • the guide body can easily be glued to a correspondingly long connecting element, which enables simple and reliable adaptation to the respective Lengths and dimensions can be made.
  • the slide is expediently held in the shut-off position by means of a spring element.
  • the slide can therefore be moved against the spring force to release the flow channel by means of a suitable actuating device.
  • Fig. 1 shows an exploded view of a ventilation device with a slide 2, which on two guide bodies 4 can be moved back and forth at least in the direction of arrow 6.
  • the slide 2 contains in its central guide part 8 two slots 10, in which bolts 12 of the guide body 4 engage.
  • the slots 10 run obliquely to the direction of arrow 6 with the result that the slide 2 can also perform a movement transversely to the direction of arrow 6.
  • a curved shape of the slots mentioned is indicated by dash-dotted lines, as a result of which a favorable adaptation of the force required to move the slide 2 to the path covered can be achieved. So it can be particularly useful to initially provide small distances for the movement when moving the slide from the shut-off position to the open position.
  • the direction of the arrow 6 coincides with the direction of flow of the air flowing through the ventilation device.
  • the slide 2 has two legs 14, 16 which are connected to one another by the central guide part 8.
  • the guide part 8 has a lower guide surface 18 with which the slide 2 rests on the guide surfaces 22 of the guide body 4.
  • the end face of one leg 16 is also designed as a guide surface 20, which rest on further guide surfaces 24 of the guide body 4. It can be seen that a functionally reliable guidance of the slide 2 is thus ensured.
  • the guide bodies 4 are connected to one another by means of a connecting element 26.
  • the guide body and connecting element are expediently made from a single piece, in particular by injection molding or pressing a suitable plastic, manufactured.
  • the guide bodies 4 are approximately stepped, a shoulder 28 being present between the guide surfaces 24 and 22.
  • the guide bodies 4 have bores 36 in their end faces 34. If the slide 2, as indicated by the dash-dotted lines, is placed on the guide body, it is in the shut-off position. By contrast, the open position is indicated by the thin lines. It can be seen that the slide 2 with its guide surfaces 18, 20 is reliably guided by means of the guide surfaces 22, 24 of the guide body 4 when moving from one position to the other and that tilting or jamming is avoided with certainty.
  • FIG. 2 shows a section through the ventilation device according to FIG. 1, which is now installed in a frame 38, in particular a window or the like.
  • the slide 2 is in a flow channel 40, which basically represents a connection between the outer space 42 and the inner space 44. It should be particularly pointed out that the ventilation device is installed directly in the frame 38 or the flow channel, without additional components such as a housing being required. The material and cost savings achieved with this are obvious.
  • the outer leg 14 of the slide 2 extends over the entire height H of the flow channel 40.
  • the slide 2 or its guide part 8 bears directly on the upper inner wall 46 of the flow channel 40 or on the frame 38. As already stated above, the slide 2 rests on the two guide bodies 4.
  • the guide bodies 4 are each arranged on the long sides of the flow channel, only one guide body being shown here, of course.
  • the leg 14 rests with its sealing surface 48 against a stop surface 52 of the connecting element 26 via a sealing element 50.
  • the sealing element 50 like the entire slide 2, extends in the longitudinal direction, that is to say here perpendicular to the plane of the drawing. It should also be particularly emphasized that 4 stop surfaces are also formed by the guide bodies arranged at the respective ends of the flow channel, which are assigned to the sealing surfaces of the slide 2 present on the lateral edges. Since the slide 2 rests with its guide part practically uncut on the inner wall 46, a good seal is also achieved there.
  • the arrow 54 indicates that, in the position of the slide 2 shown, practically no air exchange can take place between the outer space 42 and the inner space 44.
  • a weather protection strip 56 is also provided on the outside 42 to prevent the ingress of rain or snow.
  • the facing grid 30 has a second stop surface 58, which extends approximately over the lower third of the total height H, on which the slide 2 bears with its leg 16 or its sealing surface 60 there. Because of the U-shaped Forming the slide is thus achieved a double seal in connection with the two fixed or connected to the frame 38 stop surfaces 52, 58.
  • a spring element 62 is also provided, which is connected on the one hand to the slide 2 and on the other hand to the guide body 4 or, if appropriate, also directly to the frame 38 in order to hold the slide 2 in the illustrated shut-off position.
  • the wind pressure indicated by the arrow 54 acts on the slide 2 in such a way that it is pressed into the shut-off position.
  • FIG. 3 shows the ventilation device with the slide 2 in the open position, in which the flow channel 40 is released and the connection between the outer space 42 and the inner space 44 is established.
  • an air flow from the outside 42 to the inside 44 can occur. It does not need to be explicitly mentioned that the air flow can of course also take place in the opposite direction. If one starts from the flow direction shown, the slide 2 would be moved from the shut-off position shown in FIG. 2 to the open position according to FIG. 3 by movement essentially counter to the flow direction. Suitable actuating devices are available for this purpose, which will not be explained further here.
  • the air flow winds through the ventilation device in an approximately meandering manner, with the deflections also resulting in a not inconsiderable reduction in noise between the outside and the inside. It is particularly important here that practically no appreciable flow resistance is achieved in area 66, that is to say in the entry area of the air flow, because the slide 2 is pushed through the distance L into the outer space 42, L being equal to, even greater than the total height H of the flow channel 40. In the central area 68 of the flow channel 40, however, there is a cross-sectional constriction and the air flow subsequently passes through the veneer grille 30 into the interior 44.
  • the sealing element 70 can also be seen on the guide body 4, by means of which a reliable seal is provided in the shut-off position is reached at the end of the flow channel 4. It should be expressly pointed out that, in a preferred, alternative embodiment, the second stop surface 58 cannot be arranged on an additional facing grille, but on a connecting strip which is attached directly to the end faces 34 or is even made with this in one piece.
  • FIG. 4 schematically shows an exemplary embodiment of a ventilation device whose slide 2, which is essentially movable in the flow direction, has three legs 72, 74, 76.
  • a component 78 which is fixedly connected to the frame 38, is arranged in the flow channel 40 and basically has the same structure as the slide 2. In the illustrated shut-off position, the legs of the slide 2 and the component 78 are aligned with one another.
  • the slide 2 and also the component 78 have a lining 80, 82 made of noise-protecting material between the legs.
  • the linings 80, 82 are expediently like in their surfaces shown, executed rounded, so as not to oppose too much resistance in the open position of the air flow.
  • a facing grille 84 with weather protection strips 86 is also provided for the outer space 42.
  • the slide 2 is arranged entirely within the flow channel 40, and it is also in the open position there. It should be emphasized that in this exemplary embodiment, as shown, the sealing surfaces of the slide 2 in the shut-off position are diametrically opposed to the stop surfaces or sealing surfaces of the component 78 firmly connected to the frame 38, between the legs of the slide 2 and the component 78 there are practically no gaps.
