Definitions

  • the invention relates to a sectional flap for ventilation and air conditioning systems according to the preamble of claim 1.
  • Sectional flaps are used in the air outlet openings of ventilation and air conditioning systems for shut-off and throttling tasks as well as in the case of heat recovery units as a bypass flap.
  • Such link flaps are known, for example, from the Swiss patent specification 667 709.
  • the usual, customary design of the link flaps has the disadvantage that either the entire link flap, consisting of the frame inserted into a housing and the slat profiles that can be pivoted in the frame, must be replaced during repairs, or that repair accessibility is required both from the housing side and from the airflow side must be given. Since repairs are often necessary in the operation of sectional flaps as a result of wear and soiling, the known constructions involve the replacement of individual elements of the sectional flap without disassembling the ventilation units at considerable cost.
  • Link flaps are increasingly being used in heat recovery units, for example in order to change the passage cross section of a bypass channel bypassing the heat recovery unit in the opposite way to changing the passage cross section of an air duct passing through the heat recovery unit.
  • the link flaps required for heat recovery units have been assembled so far, starting from and based on commercially available link flap designs. However, this did not meet the requirements for a compact design of the link flap and for minimal costs.
  • the known and common link flaps one was set in standards Leak tightness achieved only in that the lamella profiles were provided with lip seals or other sealing elements made of rubber or similar elastic material known from the German patent specification 26 14 284 on their lamella edges interacting in the closed position of the sectional flap.
  • the object of the invention is to provide a sectional flap which allows simple and cost-saving replacement of individual elements for maintenance and repair work without dismantling the ventilation units, which has a compact and inexpensive construction for use in heat recovery and which, if a tightness after Standard is required, no special rubber sealing elements are required on the lamella profiles.
  • the link flap contains a rectangular frame, the horizontal frame parts 1 and 2 and vertical frame parts 3 and 4 of which surround an air opening A, in which five slats 5 are pivotally mounted about their horizontal center lines 6 in the exemplary embodiment shown.
  • the link flap is supplemented, for example in the case of a heat recovery device, to change the cross section of an air duct leading through the heat recovery device and simultaneously the cross section of a bypass channel bypassing the heat recovery device, so that the frame next to the air opening A is one of the extended horizontal frame parts 1 and 2 and includes a second air opening B surrounded by a third vertical outer frame side part 7, in which second slats 8 are pivotally mounted about their horizontal center lines.
  • FIG. 1 shows the fins 5 of the first air opening A in the closed position and the second fins 8 of the second air opening B in the open position.
  • the same number as the lamellae 6 have gears 9 rotatably mounted, with which the lamellae 5 are connected at one end and via which the lamellae 5 are in engagement with one another. Between the gears 9 and the second plates 8 there is a connection described below, so that the gears 9 together with the first plates 5 also second slats 8 are engaged with each other.
  • the slats 5 are connected at their other end to receiving disks 10 which are rotatably mounted on the vertical frame part 3.
  • the second lamellae 8 are connected at their end facing away from the gear wheels 9 with similar receiving disks 11, which are rotatably mounted on the vertical frame part 7.
  • the actuation of all the slats 5 and 8 takes place centrally on a drive pin 12 which is inserted, for example, with a square into any selected receiving disk 10 and slat 5.
  • the slats 5 and 8 consist in the usual manner of a hollow profile that has a square opening on the slat center line, into which the drive pin 12 can be inserted in the slats 5 and the connection described with the slats 8 Gears 9 engages.
  • holders for the lamellae 5 and 8 are arranged which, in the embodiment of the link flap shown in FIGS. 1 to 5, consist respectively of holding tabs 13 which are arranged in pairs on the gearwheels and receiving disks there are fixed support lugs 14 on the gearwheels or receiving disks and fastening wedges 15 removably arranged opposite one another on the gearwheels and receiving disks.
  • the retaining tabs 13 and the support tabs 14 and fastening wedges 15 each lie opposite one another on both side surfaces of a lamella 5 and 8, respectively.
  • the retaining tabs, support tabs and fastening wedges preferably have rib-like projections 16 which engage in matching groove-like depressions 17 on the lamella side surfaces, as a result of which the lamellae between the holding elements 13, 14, 15 in positioned in the correct position and against moving in the slat plane are fixed.
  • the slat-shaped cross-sectional shape tapering in a wedge-shaped manner towards both slat edges supports the securing of the slats against displacement in the holders on the gear wheels and on the receiving disks.
  • the gear wheels 9 and the receiving disks 10 are rotatably mounted on the vertical frame parts 3 and 4 in such a way that they can be pulled off into the air opening A from the vertical frame parts. After pulling out a lamella 5 as described above, its gear 9 and / or receiving disc 10 can also be easily removed from the frame of the link flap for repair work. As FIGS.
  • each lamella 8 can be pulled out analogously to the slats 5 after the fastening wedge 15 has been removed from the holding disk 11 from the holding tabs 13 in the slat plane.
  • the support tabs opposite the releasable fastening wedges and on the same are on the gearwheel 9 and on the receiving disk 10
  • Side surface of the lamella adjoining retaining tabs are designed as continuous strip-shaped covers 19 which cover gaps which may form between the lamella 5 and the gear 9 or between the lamella 5 and the receiving disk 10 in a sufficiently tight manner.
  • the gear wheels 9 have a recess on the side facing the lamellae 5, into which a helical compression spring 20 is inserted. By means of this spring 20, which is supported on the one hand on the gear 9 and on the other hand on the lamella 5, the gear 9 and the receiving disc 10 are pressed sufficiently tight against the vertical frame parts 3 and 4, respectively.
  • FIG. 1 A further advantageous design measure of the link flap according to the invention, which avoids or makes unnecessary conventional special rubber lip seals or other rubber sealing elements on the contacting lamella edges, is shown in particular in FIG.
  • the slats 5, similar the slats 8 come in the closed position at their slat edges directly, without additional elastic sealing means, in metallic contact.
  • the lamellar edges are also formed with a cross section, which is composed of a projection 21 and a recess 22 and essentially corresponds to the shape of a tooth and a tooth gap of an involute toothing.
  • the slat edges can be designed such that they come into contact shortly before reaching the vertical closing end position of the slats shown in the right part of FIG.
