Description

The present invention relates to a device which is mounted on the outside of the building wall and which allows a roller shutter, which is mounted below a building window opening so that it partially covers the window opening from below when it is pulled up. A commonly existing upper roll-up store, which is mounted at the top of the window opening, can be partially lowered. Due to the partial pulling up of the lower roll-loading a variable slot can be made at any height. This serves to protect against insights from outside and to regulate the sun's rays.

The production of such a variable slot is in the EP 1 524 400 A1 described by means of an upper roll-loading and a lower roll-loading. However, the cited document does not show how the rain water that accumulates in a box below the lower roll-store, should be removed from this.

This problem arises especially when applied to building window openings. In order to overcome these drawbacks of the cited prior art, the object of the present invention is to provide a device with a lower, liftable roller shutter for building window openings, which should fulfill the following conditions:

• 1. The device should be able to be installed or retrofitted,
• 2. the rainwater should not be collected in a collection box, but simply flow freely,
• 3. The device should be structurally simple, with a known lifting device should be used for pulling up the lower roll-loading,
• 4. The device should be on the outside of each building wall, regardless of their

• 6. The lower roller shutter should be provided with lamellae, by their connection with each other a gap between the slats is present
• 7. Instead of a slat-roll-Laden also a blind or z. As a fly net be used, these materials must either be rain-permeable itself or should be provided with surface-arranged openings and
• 8. no part of the device should protrude into the area of the window opening in rolled-up, lower roller shutter in this.

This object is achieved by a device with a lower, roll-up roller shutter for building window openings according to the description, the drawings and the claims.

The proposed innovation will be explained on the basis of drawings. It shows:

1 a side view with the device according to the innovation,

2 a view I according to 1 , without bottom roller blind,

3 a front view of a known lifting device,

4 a plan view from above of the illustration according to 3 .

5 a section II-II according to 4 .

6 a section IV-IV according to 5 .

7 a section III-III according to 3 and

8th a partial perspective view of an embodiment of a vertical element.

On both sides of the respective window opening 6 is each a vertical element 100 appropriate. Every vertical element 100 has a mounting cheek 101 and parallel to this a guide cheek 102 on. The mounting cheek 101 is slightly wider than the guide cheek and is used for attachment to the building exterior wall 5 ,

The lower roller shutter 200 is, as usual, under spring tension on a roll-loading drum 201 wound. At the top of the lower roll-up is a pull tab 203 attached, on both sides, in the area of the guide slot 103 , one traction device each 202 , z. B. in the form of a wire rope is attached. The roll-up drum is around the drum longitudinal axis 204 rotatable, parallel to the bottom edge of the window opening 6 is aligned.

At the bottom of each vertical element 100 is next to the guide slot 103 a footbridge 15 attached. Both bridges 15 are parallel to each other, from the projecting, perpendicular to the building exterior wall 5 arranged. In these bridges 15 is the roll-up drum 204 rotatably mounted.

At the two bridges 15 is also an introducer 250 rotatably mounted, parallel to the drum longitudinal axis 204 is aligned, wherein the outer surface of the insertion roller 250 approximately centrally under the lower end of the respective guide slot 103 is arranged. This ensures that the traction means 202 the lower roll-up with Help the lifting device 300 safely in the guide slot 103 Introduce and the lower roller shutter 200 in the guide slot can move up and down. The lower roller shutter 200 has from the introduction role 250 such a distance that in the area between the lower roller shutter 200 and the introducer roll 250 with partially raised lower roll store a roll shop area 205 is present, through whose slats columns rainwater can drain. When fully rolled lower roll-store this area is completely free.

The length of the insertion roller 250 is slightly larger than the width of the lower roll-up 200 ,

If with partially raised lower roll shop 200 Water flows through the sloping rain and reaches behind the lower roller shutter. It flows unimpeded between the raised lower roller shutter and the outer wall of the building 5 as a result of the guide slot 103 there is a gap. The lower roller shutter has due to the arrangement of the vertical elements 100 no contact with the building exterior wall 5 ,

The lower roller shutter 200 is slightly wider than the window opening 6 because he's on both sides in the guide slots 103 is guided, which are arranged near the window opening. In case of very heavy rain, the water simply runs over the roller shutter surface when the lower roller shutter is raised 205 laterally.

In the event of snowfall or freezing, the lower roller shutter can be completely rolled up by means of a cold sensor.

It is an essential feature of the proposed device that the section between introducer 250 and the roll-up drum, namely the roll-up area 205 below is completely free and there is no box-like structure in which water could accumulate. This is achieved by the attachment of the two webs according to the invention 15 ,

The lower roll-up can top with a cover 16 be covered, the bottom open and both sides of the jetties 15 can be attached.

The lifting device 300 can completely with a capsule 17 are obscured, with the upper capsule surface 19 is formed obliquely forward, so that the rainwater can drain from.

As lifting device 300 For example, any of the embodiments of the prior art mentioned may be used.

Here, the known embodiment is chosen, the two winding drums 303 has, motor-driven and by means of two angles 18 above the window opening 6 on the building exterior wall 5 is attached.

The two winding drums 303 are with spiral grooves 308 provided on each of which the traction means 202 are wound, the winding drums by means of a drive shaft 301 by a motor 304 around the longitudinal axis 302 which can be switched either directly via a cable inserted into the building or via a remote control.

On the drive shaft 301 are each a sliding bush on both sides 309 attached, on which an elongated guide slot 310 is provided, in which a feather key 311 is attached, which allows a longitudinal movement of the winding drums.

In 3 is the position of the winding drums with the lower roller shutter raised 200 and in 4 the position of the winding drums shown. The traction means 202 When applied to the present invention, they are wound up in the area of the vertical elements 100 to expire, as in 7 you can see.

The longitudinal movement of the winding drums takes place by the transverse force in the up and down movement of the lower roll-loading 200 , This effect is known.

Instead of this described lifting device, any other, belonging to the aforementioned prior art lifting device can be used with the artisanal required adaptation to the proposed innovation.

The arrangement of the roll-up drum 201 and the introducer roll 250 can also be changed in the context of the present innovation so that the roll-loading drum 201 can be arranged above the insertion roller. Condition is that no part over the lower edge of the window opening 6 survives and that a roll-shop area 205 can be produced.

The upper roller shutter 20 is from the on the window opening 6 seen, in front of the window 21 , arranged in the usual way.
