Abstract

An insect screen fitting for a venetian blind shutter has screen strips (10) clipped between the louvres (1) on one side of the shutter. The screen strips extend over the outer ends of the shutter an both slides with a sliding fit with the edges of the aperture. The seal is improved by fitting foam or brush seals to the vertical sided of the aperture and with special seals between the top louvre and the shutter support system and with a U-cross section flexible seal under the bottom louvre. The screen strips can be of uniform width enabling them to be cut from a standard strip and applied to the edges of the louvres with a clip fitting.

Description

The invention relates to a slatted blind with spaced-apart in the lowered state, pivots that can be swiveled around an axis, which are gathered together when the lamella blinds are opened become.

Slat blinds of this type are used in particular for shading and / or darkening of Rooms. Known slat blinds have been arranged horizontally about a central axis Swiveling slats, which are gathered when pulling up the store. Besides One knows also insect roller blinds, in which a fine net led in guide rails which are arranged in a window or door revival. Do you want slat blinds and Combining insect screen roller blinds, this practically requires a double effort by both the drive for pulling up and the side guides made double Need to become.

It has also been proposed, a slat blind and an insect repellent device to combine. Swiss patent CH 690968 relates to a shutter or a Venetian blind with swiveling sun blades, each sun blade being pivoted in one Condition with an adjacent sun blade forms an air inlet slot. This shutter or the blind is characterized in that at each Sun-lamella at least one insect-protection lamella is arranged and that the insect-protection lamella at least in the tilted state of the sun blades on an adjacent Sun lamella rests. According to the embodiment shown in the patent each insect screen is attached only to the upper solar lamella and is located at the lower solar lamella only. When swiveling the sun blades, the insect protection lamellae shift relative to the neighboring sun lamellae, where they are. This requires that the insect-resistant fins are relatively stiff must be trained. In the patent also measures are specified in the top and bottom lamella prevent insects from entering the building in question should. In the area of the window sill this measure consists in that at the bottom sun-slat hangs an insect-resistant slat, which loosely on the window sill rests. Due to the mentioned stiffness of the insect protection slats but this is Measure not very effective. It must be noted that the window sills very much may be formed differently by, for example, weather legs of window frames extend into the area of the store. If the slats are pivoted into their vertical position, lifts the lowest insect protection lamella completely from the window sill and can therefore no longer prevent the entry of insects. Regarding the lateral seal In the area of soffits, nothing is mentioned in this document. An essential The disadvantage of this slat blind is that it requires specially manufactured slats. In the illustrated embodiment, moreover, the pivoting range of the slats limited to about 45 °, because each insect screen lamella on a ledge under her arranged sun lamels hangs.

The patent application FR 1364674 shows a store with orientable slats, in each case one end of each lamella with a lane covering the whole window opening Tissue is connected. The document JP 2000110462 relates to a similar store like that previously mentioned document from France. There are none in these documents References to a seal above the topmost slat, below the bottom slat and laterally of the slats in the Leibbereich.

Based on this prior art, the invention has the object, a To propose slat blinds that are easily manufactured in different dimensions can and in the penetration of insects also laterally in the area of the soffit reliable is prevented.

This object is achieved according to the invention in that in each case between two adjacent Slats an insect repellent strip made of a flexible material is attached and that this insect repellent strip is longer than the lamellae, so that it laterally over the lamellae protrudes.

By said lateral projection of the existing of a flexible material insect repellent strips It is very easy, these strips in the area of the window reveal at one To let stand on surface and thus the penetration of insects not only between the Slats, but also on the sides of the slat blind in the area of the soffit to prevent. This surface may be the soffit itself, but is beneficial to the surface of an in the soffit arranged soffit profile. In addition, the packaging of the inventive Store contrary to the mentioned solutions with continuous fabric extremely simple. Because with a certain type of fins the distance between the lamellae is always the same, the insect repellent in the form of a band can be kept ready be whose width corresponds to the distance between the slats and thus only on the required length must be cut. Another major advantage of Invention is that they are applied to a commercial slatted blind and at the lamellar store at most minor changes are.

According to a further embodiment of the invention, the soffit profile is with a guide rail preferably connected in one piece for the slatted blind. Because every slat blind this type anyway has lateral guide profiles, this embodiment is particularly inexpensive and easy to assemble.

According to a further embodiment of the invention is on the soffit a soft Pad, preferably in the form of a brush, arranged with which the insect protection strips in the area where they protrude laterally over the slats, in each pivotal position the lamellae are in contact. This will make the side seal in the reveal area further improved.

There are several options for attaching the insect-protection strips to the slats conceivable. Particularly preferred are the insect protection strips by means of a snap-in Attachment to a longitudinal edge of each blade tightly fixed.

For sealing the lamellar store against the ingress of insects is also preferable attached to the top lamella a seal, namely a so-called lintel seal and a window sill seal may be attached to the lowest slat. The latter is preferred a profile with a semicircular cross-section and a semi-circular profile, the lowermost lamella facing away from the soft layer. The soft layer may be a brush or a foam layer.

An embodiment of the invention will be explained in more detail below with reference to the accompanying drawings, for example. In the drawings shows

In Figures 1 and 2, the slats 1 in its horizontal position with continuous Lines shown. Each lamella 1 is pivotable about an axis 6, with its longitudinal edges 2, 3 when panning a way back, which is indicated by broken lines 4. The reference numeral 5 denotes the slats in a vertically aligned state in which they overlap slightly so that the store does not let any light through. A drive 7 for the Store is arranged in a housing and connected to a connecting rod 8. Of course could the drive 7 also be equipped with a motor, in which case the connecting rod would be omitted. The slats 1 are in a known manner with spacer strips. 9 connected, which is the maximum distance between two adjacent slats in open State of the store determine.

As can be clearly seen in Figure 1, is in each case between two slats 1 at the window facing edge of an insect screen in the form of a strip 10 of a flexible Material attached. The material is preferably a fine-meshed fabric, but may as well a film which is advantageously provided with a grid of fine holes to the To ensure air circulation through the store. Fasteners 11 with which the insect repellent is fixed to the fins 1, are indicated in Figure 1 only. It can work act around a snap connection, which with a flanged edge of the lamella interacts. The fastening means 11 can also be used as brackets or wires be formed, which engage in small holes, for this purpose in the area of the edge the slat 1 were attached. In this way, the passage of insects between the slats 1 impossible. Because when pivoting the slats of the distance between their lying on the same side longitudinal edges always remains the same obstructed the insect repellent strip 10 not this pivoting movement. Actually, it does not matter at which point of the slats 1 of the strip 10 is attached. As long as this place at all Slats is the same, also remains the distance of these points from one slat to the next during parallel pivoting of the slats always the same. For fixing the strips 10 on the slats 1 but one chooses advantageous longitudinal edge 3 of the slats 1, as it shown in the present example. In Figure 1 is also facing on the window Side of the lamellae 1 a spacer band 9 drawn. This inner spacer band favors when shirring the slats, the folding of the insect protection strips 10th

To prevent the passage of insects even at the top of the store is there arranged a crash seal 12, which may consist of the same material as the insect repellent 10. The lintel seal 12 is with its lower edge in the previously described Type attached to the top lamella and with its upper edge, for example, on the housing of the drive 7. If the lamellae are pivoted, the lintel seal is folded and assumes about the indicated by a broken line 13 location. The required The width of the lintel seal depends on the height of the lamella package, which in turn depends on the height of the relevant building opening. The fall seal can at Need to be composed of several insect repellent strips.

Figure 2 shows the lower end of the store in the fully lowered state. With the lowest lamella 1 the store is connected to a lower end profile 18, to which a window sill seal 19 is arranged. The latter consists of a profile 20 with a semicircular cross-section and a soft pad 21. The pad 21 may, for example, a brush with soft bristles or a layer of soft foam. As the figure clearly shows, the window sill seal 19 thus constructed is in each pivotal position of the slats. 1 on the windowsill 22 and also fits bumps, such as a weatherboard 23 without problems.

FIG. 3 shows the store in a raised state in which the lamellae 1 are gathered in such a way are that only a small distance remains between them. This distance is but still enough to the folded insect protection strips 10 between the slats. 1 take. Also, you can clearly see in this figure, the crash seal 12, in the area the drive 7 finds enough space to fold.

Of course, the insects must also pass between the lateral ends of the store and be denied the window revocation. How this is achieved is best in FIGS and 5 to see. First, it is visible in FIG. 4 that each lamella is laterally known in a known manner is guided in a guide rail 14 by a guide pin 16 in this guide rail 14 engages. In addition to the guide rail 14, a soffit 15 is arranged, that the inner longitudinal edge 3 of the slats 1 slightly surmounted towards the window when the Slat 1 is aligned horizontally. The soffit 15 can with the guide rail 14 be formed in one piece. As you can see, the front side of the slats remains to be wiped 1 and the soffit 15 a narrow gap, for the mobility of the slats is required. This gap is closed by the insect protection strip 10 by this is longer by an amount than the slat 1, thereby the slat 1 projects laterally and forms a soffit seal 17 which contacts a soft pad 24 at all times stands, which is attached to the soffit 15. Just like the previously mentioned edition 21 the sill seal 19 may also be the support 24 is formed as a brush. The supernatant 17 thus forms together with the support 24, a seal in the frontal view can be seen particularly well in Figure 5.

Thus, the inventive slat blind offers in addition to the protection against solar radiation also a reliable protection against the ingress of insects.
