Definitions

  • the invention relates to a blind for covering ventilation openings in buildings according to the preamble of claim 1.
  • Such arrangements used as ventilation devices are e.g. B. known from DE 36 06 563 A1.
  • This document describes a ventilation device for building roofs with a frame and in this frame pivotably arranged slats, which overlap each other in the closed position in the direction transverse to their folding axes and overlap the walls of the frame supporting them at their upper edge.
  • Each slat is provided at its ends with a downwardly extending end wall and has a drainage channel for water at the rear edge.
  • the top of the slat has an upright deflector lip that extends parallel to the drainage channel and protrudes beyond the end walls of the slat. This is to prevent the passage of water from the outside into the ventilation opening when the slat is swiveled up, in that the deflector lips collect the water when the slats are opened and discharge it to the outside of the arrangement.
  • a generic venetian blind in which the lamellae are each encompassed by a lamella bearing on the end face, a flange being formed on a lamella bearing for connection to the Adjustment of the push rod causing the slats.
  • the pivot pins, with which the slats are rotatably mounted in the frame, and stop pins for limiting the exposition of the slats in the horizontal position are molded onto these slat bearings.
  • the invention has for its object to show a generic blind in which the slats are secured against ingress of water when pivoting through a thrust seal without a separate lateral seal and in which the slat is arranged relative to its storage such that thermally induced changes in length can be included.
  • the lamellae are held in the lamellae bearing, with the lamella being adjusted over the underside of the integrally formed flange of the lamellae bearing and the lamellae bearings being connected to the lamellae via lamella stiffening profiles which penetrate the lamellae in their longitudinal extent.
  • This arrangement including the push rod serving for the adjustment, lies inside the frame and the slats are opened by pivoting into the opening delimited by the frame. This means that lifting work does not have to be carried out with no swiveling movement against a load lying on the lamella, which permits a lighter construction with increased operational safety.
  • the slats preferably used in this embodiment consist of an upper surface and a parallel lower surface, which are connected to one another by webs, the upper surface being angled towards the lower surface in its end region and then running approximately semicircularly upwards into one slightly inward section, which has an inward end section, that the lower surface on the opposite side is further angled in its end region towards the upper surface, then after a section parallel to the upper surface a substantially round section with a completes outer approach to accommodate a sealing element.
  • slats differ from the known slats in that the area in which the pivot axis is arranged, the lower surface is pulled upwards and forms an eye for receiving the axle bolt mounted in a slat stiffening profile, with the outer surface formed together with the upper surface Approach to accommodate a sealing element that is in the closed state of the slats rests on the previous slat.
  • Another essential feature is the straight section formed at the other end of the transverse extension of the slat with its short end section directed towards the slat.
  • This straight section is slightly inward, inclined towards the lamella and thus forms an open water drain rail through which the water is released when the seal attached to the next lamella - as described above - is released when pivoting until the final state of opening is discharged laterally in a known manner.
  • these lamellae are held in lamella bearings, which surround the respective end face of the lamella with webs and are essentially adapted to the lamella profile, but which only grasp the angled section in one end region of the lamella in approximately the lower third and on the side the lower surface of the lamella has a flange with a recess for receiving an axle bolt, this flange being arranged eccentrically on the swivel axis side and bores being provided in the end regions of the lamella bearing for releasable connection to the lamella.
  • These lamellar bearings are easy to manufacture and stock parts that can be mass-produced. Due to the molded flange near the swivel axis, the slats can be opened with a short opening travel of the push rod articulated on the flange.
  • These disk bearings are required in right and left versions. These differ only in the side on which the webs encompassing the lamella are arranged. However, it is also possible to use a uniform lamella bearing for both transverse sides of the lamella. In this case, webs are arranged on both sides. However, this then has the disadvantage that the distance (gap) between the lamella bearing and the push rod becomes somewhat larger, but this is of no particular importance in many versions.
  • Holes can also be arranged in the lamella bearing for securing the lamella stiffening profile against rotation, two further bores serve to fasten the lamella bearing to the lamella, they lie in the area of the front and rear lamella stiffening profile seen in the transverse extension of the lamella. The attachment is done by simply screwing.
  • end chambers for receiving a lamella stiffening profile are formed in the lamella in the end region of the transverse extension from the upper surface and the lower surface together with the angled surfaces used in each case.
  • end chambers are formed in the lamella, into which the lamella stiffening profiles are inserted. The result is a profile that further increases the stability of the lamella and into which the stiffening profiles can be easily inserted and via which the lamella bearings can be connected.
  • a continuation with respect to the disk bearings is characterized in that the closed base plate of the disk bearings is extended in a wedge shape in the longitudinal direction upwards over the part encompassing the disk, so that it extends beyond the section of the disk bearing formed from the webs and encompasses the disk section.
  • closed state of the slats forms a horizontal connection between the previous and the following slat. This effectively prevents z. B. is blown into the arrangement during windy rain, also creates an aesthetically particularly good picture of the blind.
  • the lamella stiffening profile on the pivot axis side has a contour corresponding to that of the end field in the lamella, in the transverse extension on one side a recess for receiving an axle bolt and on the other side a further recess for receiving a screw connection, and the connecting web is kept narrow.
  • short, inwardly directed serrations are formed on the recess receiving the axle bolt and semicircular channels for chip removal directed outward on the further recess.
  • the lamella reinforcement profile remote from the pivot axis has a contour corresponding to that of the end field in the lamella in the form of a right-angled triangle with a shortened side opposite one leg of the right angle and a recess with chip deflection channels for receiving a screw connection.
  • the lamella bearing is connected to the lamella via this screw connection, which is also designed in the same way for the swivel axis-side profile.
  • the chips produced when the screws are screwed into the profile, which is preferably made of aluminum, can be discharged through semicircular channels formed on the recess without impeding the drilling process.
  • the lamella stiffening profiles project beyond the lamella on both sides, and an elastic intermediate piece is arranged between the lamella and the lamella bearing.
  • This elastic intermediate piece acts sealingly between the lamella floating on the lamella stiffening profiles and the push rod.
  • the downward pivoting of the slats allows a lateral seal between the slat and the frame against lateral Penetration of water in the closed state of the slats can be dispensed with, since, according to a particularly expedient development of the arrangement of the frames, has a transverse web with a molded-on profile projecting beyond the slat bearing together with the end region of the slat, the profile being designed to accommodate a run-in seal between the slat and Frame wall bar works.
  • This run-in seal is a known sealing element and can easily be inserted into the frame profile and can be arranged in such a way that the deformation of the seal which occurs when the lamella starts up against the relatively soft seal also causes it to rest against the corresponding frame section. For an adequate seal, however, the effect of the seal on the lamella alone is decisive and sufficient.
  • the connection of the crossbar to the push rod is particularly important. This is all the more so since the adjustment mechanism is usually attacked eccentrically by a pneumatic component consisting of cylinder and piston on the crossmember and a torque / tilting moment occurs.
  • the traverse is connected to the push rod via retaining tabs which are bent out of the push rod at right angles.
  • the push rod has a crossing diagonal slit in the connection area of the cross member, the length of the diagonals being equal to the length of the inner diagonal of the cross member and for connecting the cross member through Slit formed flaps bent at right angles and inserted into the crossbar and releasably connected to it. This creates a particularly good and firm connection, whereby the bent holding tabs are screwed to the crossbar.
  • the adjustment of the slats takes place in a known manner by an adjusting mechanism arranged between a fixed bearing and the crossbar, and this adjusting mechanism consists of a pneumatically actuated lifting rod including a lifting cylinder, which is arranged in a pendulum-movable manner in the fixed bearing, the lifting rod being connected to a bearing of the crossbar is arranged.
  • FIGS. 1 shows a peripheral frame 1 of a ventilation arrangement with blinds.
  • This frame 1 sits with its frame base 2 on a connecting element 3.
  • This, forming a housing, rotating, in pairs opposite sides formed frame 1 is in the area in which the slats 4 are arranged, offset inwards with the recessed section 5, to which a yoke-shaped crosspiece 6, the lamella bearing 7 is arranged as a top, z. B. is molded.
  • Another frame part 8 is placed across the frame 1.
  • a profile 9 is formed on the crosspiece 6, which carries a run-up seal 10. This overlaps the disk bearing 7 and covers the expansion gap 11, in which a sealing element can be arranged.
  • a special bearing block is usually not required.
  • a flange 16 is integrally formed on the disk bearing 7 with an eye 17 which is also integrally formed and through which the axle bolt 18 is fastened with the push rod 19.
  • the slat 4 is adjusted via this push rod 19.
  • a cross member 20 is arranged between the two push rods 19. Traverse 20 is connected to push rod 19 by a screw connection 21 with retaining tabs bent out of the push rod.
  • retaining tabs 22 have a triangular shape, which results from the fact that the push rod 19 is cut diagonally at the connection point and the tabs are bent out.
  • a U-profile 23 arranged between the frame base 2 and the connecting element 3 and preferably having a longer leg on the side facing the building opening forms a water drainage channel 24.
  • FIG. 2 shows a section through several slats in the closed position, including the adjustment mechanism.
  • the open position is also shown.
  • each lamella 4 with its end remote from the swivel axis in the transverse extent, engages under the end of the lamella 4 arranged in front of the swivel axis, so that it can be opened by swiveling downwards and thus opening without lifting work afford and even using the load for the opening process.
  • the adjustment of the slats 4 takes place via an adjustment mechanism 25 with a cylinder 26 and a lifting rod 27.
  • This adjustment mechanism 25 is arranged in a known manner in a fixed bearing 28 on the upper section of the frame 1 so as to be able to oscillate.
  • the lifting rod 27 extends from the cylinder 26, it moves the push rod 19, which acts on the fins 4 via the flanges 16.
  • the lifting rod 27 is articulated to a bearing 30 formed from two parallel flanges 29 with a transverse bolt. These flanges 29 together with bearings 30 are fixed to the cross member 20.
  • the slats 4 can be adjusted either via a central or decentralized adjustment mechanism 25 or via two or more adjustment mechanisms arranged parallel to one another.
  • the adjustment mechanism 25 is arranged approximately in the middle of the cross member 20, in the case of the parallel arrangement on the sides.
  • the bearings 30 can be arranged directly on the respective (right and left) push rod 19.
  • the adjustment mechanism 25 can be actuated pneumatically or electrically, in each case a switchover for an opening or a Closing should be provided by hand.
  • the medium, for. B. CO2 be taken from an existing network or from z. B. arranged in an alarm box CO2 bottles. This means that this device is also suitable for extracting smoke and heat in the event of a fire.
  • the circuit can also be designed so that in the event of a drive power failure, the slats are either locked if opening is to be prevented or open inwards if opening is required.
  • the arrangement according to the invention is the only suitable design so far, since it opens only by swiveling inwards, but possibly also in an emergency under the effect of its own weight Support of an overlying load against which additional lifting work has to be done in all known arrangements when opening.
  • FIGS. 3 to 5 show an exemplary embodiment of a disk bearing 7 which is preferably made of aluminum.
  • 3 shows a view of the side with the integrally formed webs 12, 13 and the eye 17 and thus of the side that surrounds the lamella 4.
  • the lamella bearing consists of a base plate adapted to the contour of the lamella with almost all-round webs 12, 13 and an eccentrically formed flange 16.
  • the upper web 12 runs horizontally up to the end region 31 remote from the pivot axis and is then angled and goes in the direction of the lower web 13 into an almost semicircular end section 32.
  • the lower web 13 likewise initially runs horizontally, including the flange 16 arranged on the pivot axis side, and is guided upward in the end region 31 and ends approximately parallel to the section 32 of the upper web 12.
  • a wedge-shaped projecting portion 33 is formed as an extension of the base plate, which forms an approximately horizontal closure in the side region of the slats 4 in the closed state of the slats 4 and protects against the ingress of blowing water.
  • the molded flange 16 has a recess 34 in the eye 17 for receiving the axle bolt 18.
  • a recess 35 for receiving the axle pin 15 is made in the base plate on the swivel axis side and adjacent to it is a bore 36a for screwing the disk bearing 7 to the disk 4.
  • a further hole 36b for screwing the disk bearing 7 to the disk 4 introduced with a locking cam 37, a further cam 38 can be arranged adjacent to this as an additional anti-rotation device for the lamella reinforcement profile 14a to be used in this end region 31.
  • a slat 4 is shown in side view in FIG.
  • This preferably made of transparent or translucent plastic lamella 4 consists of an upper surface 39 and a substantially parallel lower surface 40, which are connected by webs 41.
  • the upper surface 39 is angled in an angled section 42 in the direction of the lower surface 40 and then passes over an approximately semicircular section 43 to which a slightly inwardly inclined vertical section 44 adjoins with an inward end section 45. In its closed section, this end area 31 forms the end chamber 46 remote from the pivot axis.
  • the end section 47 is by bringing the lower surface 40 in an angled section 48, a subsequent section 49 parallel to the upper surface 39, an almost round section 50 and one outer shoulder 51 is formed, a seal 52 (FIG. 2) being inserted in the outer shoulder 51 and extending over the entire longitudinal extent of the lamella 4, including lamella bearings 7. In the closed region, this end region 47 forms the end chamber 53 on the swivel axis side.
  • FIG. 7 shows a side view of the lamella stiffening profile 14a remote from the pivot axis. It is approximately triangular in cross section with a shortened side and is thus adapted to the end chamber 46 of the lamella 4.
  • Several semicircular recesses 54 serve to reduce the weight of this component, which is preferably made of aluminum, and, by reducing the contact surfaces in the end chamber 46, facilitate the introduction of this component, which extends over the entire length of the lamella 4.
  • An anti-rotation device 38 shown in FIG. 3 can protrude in the recess 55 on the shortened side of the profile 14a.
  • This lamella stiffening profile 14a has a recess 56, via which the lamella 4 is screwed to the lamella bearing 7.
  • Semicircular bulges are provided in this recess 56 as chip removal channels 57 in order to simplify the penetration of the screw connection into the aluminum component and to prevent "lubrication" of the thread.
