Definitions
- the invention relates to a device for setting a flow cross-section in ventilation systems by means of mutually adjustable louvre flaps which are connected to one another on the outer edge via meshing gears for exercising the synchronous opening and closing movement, with rotary bearings being provided in the associated edge regions of the ventilation ducts the louvre flaps are made of light metal hollow profiles.
- Such blinds for regulating a gas flow are for example from DE-GM 77 33 241, DE-91 06 188-U1, DE-93 14 681-U1, DE-26 39 907-A1, GB-20 08 742-A or US - 5,454,757.
- louvre flaps are installed in air ducts and penetrate the air duct walls with their pivot pins, with at least one side of the pivot pin being equipped with intermeshing gearwheels such that the actuation of one flap automatically contributes to the synchronous movement of the other flaps. It is also known to produce these louvre flaps from profiled steel elements, which has advantages over light metal flaps depending on the application. This other construction is but as a rule very similar, especially with regard to the synchronization of the opening and closing movements.
- the louvre flap, the gearwheel assigned to this flap, a plastic bearing end cap and a plastic bearing cover arranged outside the ventilation duct are arranged coaxially to one another in the position of use and by means of two elements which penetrate the elements or in screw channels of the louver damper engaging fastening screws are interconnectable and fixable against each other.
- gearwheels are designed as gearwheel fragment elements with two opposing tooth regions which essentially cover a range of approximately 100 °, with a central engagement region for a pivot pin which may engage there.
- the invention also provides that the plastic bearing end cap has opposite wings extending into the area of the teeth of the gear fragment elements, which seals this end face when in contact with the end face of the Venetian blind flap and / or is located on the surface the gear flank elements creates a seal between these and the channel wall.
- FIG. 1 shows a simplified exploded view of the head region of a Venetian blind flap with an indicated air duct wall and in FIG
- Fig. 2 shows the front view of three louvre flaps in the closed position with assigned fragment gears.
- Recesses 3 are made in a wall of an air duct (not shown in more detail), each of which is equipped with a counter bearing ring 4, usually made of plastic, with three such plastic bearing rings 4 in a configuration as indicated in FIG. 2 are provided one above the other in the channel wall 2 on each side.
- the cross section of the ventilation duct 2 can be changed in size by means of louvre flaps denoted by 5, in FIG. 2 a closed position is shown.
- the louvre flaps are designed as plastic profiles, in the example shown they have an approximately square inner region 6, with screw-in channels 8 pointing outward on the transverse webs 7 forming the inner region, into which fastening screws 9 engage in the installed position.
- profiling 10 is attached to the outer side edges of the multi-leaf flaps 5, which enable adjacent multi-leaf flaps to engage in a sealing manner in the closed position and / or that sealing lips, for example made of rubber, can be drawn in here.
- Each louvre flap 5 is assigned a gearwheel fragment element, generally designated 11, for actuation, which has two teeth covering an angle of approximately 100 °. areas 12 on opposite sides, which are mutually engaged, as can be seen from Fig. 2.
- the gear fragment elements 11 also have an inner central recess 13 and four passage areas or screw recesses 14 offset by 90 °, which in turn are penetrated in pairs in the mounting position depending on the installation position of the fragment element 11 by the fixing screws 9, as can be seen in FIG dash-dotted line in Fig. 1 results.
- Each end face of the Venetian blind flap 5 is assigned a plastic bearing end cap 15 with a central pin 16, shown angularly in FIG. 1, which can be passed through the recess 13 for actuating the flaps 5 and can be fixed in the profile area 6.
- the plastic bearing end cap 15 has a circular shoulder 15a, which corresponds to the plastic bearing ring 4, the outer closure in the installed position forming a plastic bearing cover 17 which closes off the through hole 3 to the outside. After the elements have been put together, they are fixed against one another by means of the fastening screws 9.
- the plastic bearing end cap 15 has two wings 18 pointing outwards. is equipped, which can be shaped so that they seal the interior and / or abut the gear fragment element 11 when they are in direct contact with the front side of the Venetian blind flap 5.
- the composition can be chosen differently with otherwise the same construction, in such a way that the gear fragment elements are arranged on the outside of the air duct wall 2.
- the plastic bearing end cap 15 can also be formed from light metal
- the plastic bearing ring 4 can optionally be formed directly from the channel wall 2 by means of a bearing flange. the like more.
