Description

The invention relates to a protective device, in particular as insect repellent, for mounting on a guided in vertical Rollpanzerführungsschienen roller shutter curtain with a number of hingedly interconnected roller shutter bars (slats).

From the DE 101 48 957 A1 It is known to combine a designated there as a roller shutter curtain shutter curtain and a fly screen and additionally an awning, a sunscreen and a comparable cover sheet in a multifunctional shutter box assembly. Both the roller shutter curtain and the fly screen and the or each further cover sheet are each wound on a winding shaft, wherein the winding shafts are arranged in the common roller shutter box.

From the DE 198 25 445 A1 is an insect, visual and sun protection fabric for window or door openings known which tissue is to be attached to an existing, there called blinds roller shutter (rolling arm) as a blackout shutters. The fabric is wound up in a protective housing on a roll in the form of a spring roller blind, which is fastened in the course of installation in a building opening on or in front of a window either on the lower roller shutter end bar or on a windowsill, while then pulled out of the protective housing fabric roll beginning on the windowsill or attached to the lower roller shutter end bar. If the roller shutter curtain is then pulled up and pulled into its roller shutter box, the roller blind fabric is automatically unrolled and pulled in front of the window in an insect-tight manner.

A similar roller shutter-roller blind combination with a roller shutter at the end of the roller shutter rod (last, bottom plate) of the roller shutter mounted roller blind and a pull out of this roller blind is from the DE 196 26 124 C2 known.

At one of the DE 41 04 749 A1 known shutter-roller blind combination, the end of the local fabric or Geweberollos is provided with an end bar, which prevents their entry under the action of a spring preload in the roller blind box, and on the other hand in the extended state by means of a locking mechanism in guide rails for the armor slats (roller shutter rods ) is locked.

The invention has for its object to provide a particularly easy to assemble and manageable protection device of the type mentioned, in particular as insect protection for a window opening.

This object is achieved with the features of claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

For this purpose, preferably provided as insect protection device for mounting on a roller shutter curtain (roller armor, blackout shutters) is set up, which has a number of hingedly interconnected roller shutter bars (roller shutter profiles or slats), which are guided in vertical Rollpanzerschienen. The protective device comprises a preferably insect-sealed, hereinafter referred to as pleated fabric prefolded (pleated), d. H. Folded tissue or mesh, which is held on at least one rubber-elastic drawstring. For this purpose, this is suitably guided through corresponding openings or holes in the fabric folds of the pleated fabric. This and the or each rubber-elastic drawstring are held on end strips, in particular in the form of on the one hand a roller shutter end facing (assigned) pull bar and on the other hand, a the roller blind end remote from the fixing bar. In other words, the opposing tissue free ends of the pleated fabric are held on a respective end strip, and the pleated fabric is guided and / or held on at least one elastic rubber drawstring extending between the end strips.

In the assembled state, the serving as a pull bar end bar is attached to a roller shutter end of the shutter curtain, while serving as a fixing strip end bar is held in the assembled state of the rolling armrail rails and there is preferably clamped. In other words, the pull bar for attachment to the roller shutter end of the roller shutter curtain and the fixing strip are provided for mounting on the Rollpanzerschienen and set.

Due to the use of a rubber-elastic (rubber cord) instead of a plisseous usual, non-elastic drawstring on the one hand, a restoring force (tensile force) is maintained in each extension position of the pleated fabric between this holding end strips. On the other hand, the customary in the inelastic drawstrings loops of cords are avoided with pleated and pleated pleats, namely, by the rubber elastic drawstring draws on their minimum string length looped or contracts.

The pleated fabric is arranged in a preferably split pleated cassette, which is formed in an expedient embodiment of two preferably identical profile strips, which are mounted facing each other in mirror image. A the roller shutter end rod facing and in the assembled state suitably attached to this first profile strip takes on the pull bar, while then the fixing strip is received in the other, second profile strip.

The profile strips have, according to a suitable development, mutually facing half chambers for receiving the pleated fabric. In these, in cross-section suitably U-shaped half-chambers, the pleated fabric lies completely and invisibly in the folded state. The profile strips expediently each have a receiving chamber for the end strip, d. H. for the fabric end-side pull bar or for this fabric end side opposite fixing bar on. The respective receiving chamber is accessible via a profile longitudinal slot in an intermediate wall between the receiving chamber and the half chambers, so that a corresponding fabric edge or a fabric edge of the pleated fabric can be guided by the half-chamber and through the profile longitudinal slot in the receiving chamber.

Advantageously, however, the corresponding fabric edges of the pleated fabric is first attached to the respective end strip (pulling and fixing strip) before the respective end strip is pushed from one of the end sides of the profile strip into its receiving camera. At the same time the pleated fabric is threaded together with the fabric folds passing through rubber elastic drawstring in the profile longitudinal slot and guided in this to the opposite end.

In a further advantageous embodiment, at least one of the profile strips of the pleated cassette has a cover or a cover part on the front side of its profile narrow side. At the cover part a sliding peg is suitably formed. In the assembled state, the respective sliding peg is seated in one of the two roller-armor rails under the guidance of the pleated cassette, preferably under the guidance of both profile strip and the pleated fabric.

In the course of assembly, the pleated cassette is preferably fastened to screw openings of roll-up tarpaulin stoppers already present in the case of a roller-armor or roller shutter curtain and there on its roller shutter end bar. Suitably, the pleated cassette, preferably the profile strip facing the roller shutter end bar, for this purpose comprises a joining chamber extending in the longitudinal direction of the profile with a joining slot, via which at least one holding element fastened to the roller shutter rod and fastened in the mounting state can be inserted into the joining chamber, in particular clipped or laterally inserted.

A particularly advantageous and an independent invention performing embodiment of the protection device, in particular as insect protection, provides that the connected to the pleated fabric fixing strip is releasably fixed as end bar in or between the Rollpanzerschienen, preferably by means of wedge-clamp technology.

For this purpose, the pleated cassette expediently at its at least one end face a pivotally held and in the transverse direction to the cassette or profile longitudinally deflectable spreading or clamping bolt for clamping fix the associated with the pleated fabric fixing strip in or between the rolling armor rails. Suitably, the expansion pin is held pivotally directly on the profile strip receiving the fixing strip or on its local cover (cover part).

In an expedient development of the expansion bolt acts with a wedge-shaped to this mounting screw together so that as a result of screwing the expansion bolt relative to the mounting screw deflected (spread) and against one of the rail inner walls of the corresponding, in the assembled state associated rolling armrail under installation of the mounting screw on the opposite rail inner wall is or is fixed in the clamp.

The advantages achieved by the invention are in particular that when using a pleated fabric with a rubber-elastic drawstring in conjunction with a typically already existing in a building blind curtain (rolling arm) provided a particularly easy to install and manageable roller shutter pleated arrangement or device as insect repellent is. This arrangement or device requires a particularly simple and in particular shaftless extraction and retraction mechanism for the protective fabric. Thus, compared to an insect roller blind no winding shaft and consequently no shaft bearings are necessary so that a correspondingly simple housing or a correspondingly simple cassette with comparatively small dimensions for receiving the protective fabric is provided.

The pleated cassette can be particularly advantageous consist of two identical rails, which are deflected by the same profile strip and juxtaposed to the two-part pleated cassette mirror image. In this way, on the one hand the protective fabric in the form of pleats in the retracted state can be at least approximately completely absorbed and protected in a simple manner. On the other hand, in the extended state of the pleated one of the opposing fabric ends of the pleated and the opposite free ends of the or each rubbery drawstring be kept simple and reliable.

A particularly simple and non-destructive mounting of the protective device is realized by the wedge-clamping technique by means of a two-part spreader in the form of a Spreizbolzens and a mounting screw attached to this, in the screw, the Bolzenfreiende and the Schraubenfreiende suitably V-shaped widen or spread.

An embodiment of the invention will be explained in more detail with reference to a drawing. Show:

Corresponding parts are provided in all figures with the same reference numerals.

The 1a and 1b show in front and rear view of a shutter-pleated blind arrangement 1 as a protective device, in particular as insect protection in front of a building window or a building door. Partially is roller shutter curtain (Rollpanzer) 2 with a number of hinged roller shutter bars (lamellae) 3 shown. Of these, the in the assembled state shown with extended or lowered roller shutter curtain 2 lowest roller shutter end bar (end plate) with 3 ' designated. This has typical Rollpanzerstopper 4 on that of the in 1b shown back by means of screws 5 on the roller shutter end bar 3 ' are attached. One only on one side and only in the cutout, to the shutter hanging 2 open rolling armor rail (guide rail) 6 serves together with the opposite (not shown) Rollpanzerschiene 6 for guiding the roller shutter bars 3 . 3 ' and thus the shutter blind 2 ,

At the roller shutter end bar 3 ' is the real insect repellent device 7 attached, which is a split pleated cassette 8th with a shown in the retracted state therein practically completely recorded pleated fabric 9 includes. The pleated cassette 8th is made of two preferably identical profile strips 8a and 8b educated. In the assembled state shown is the (first) profile strip 8a the pleated cassette 8th at the roller shutter end bar 3 ' attached. The attachment is done - as out 1b can be seen - by means of holding elements 10 , which on the one hand with the first profile strip 8a connected, for example clipped or locked, and on the other hand by means of screws 5 with the lower roller shutter end bar 3 ' and there with its possibly existing stoppers 4 is screwed. The second profile strip 8b the pleated cassette 8th is by means of screwable expansion bolts 11 in the Rollpanzerschienen 6 releasably clamp-fixed. The dividing line or contact edge between the profile strips 8a and 8b the split pleated cassette 8th is in the 1a and 1b With 12 designated.

Will the shutter curtain 2 from the into the 1a and 1b shown lowered and closed position (darkening position) in the vertical direction V, so the upper (first) profile strip 8a the pleated cassette 8th automatically also in the vertical direction V upwards, while the clamp-fixed lower (second) profile strip 8b remains at the position shown. This will make the pleated fabric 9 from the fully folded state to an extended state (not shown) in which the individual fabric folds 91 ( 2 ) From the shown accordion-like position more or less unfolded and covered by the shutter hanging 2 shared opening area of the window or led the door. Will the shutter curtain 2 from any, retracted position with correspondingly extended pleated fabric 9 in the in the 1a and 1b transferred shown dimming position, this is done by means of the shutter-pleated arrangement 1 turn automatically, with the pleated fabric 9 in each case preferably in half in the two profile strips 8a and 8b the pleated cassette 8th is recorded.

How out 2 it can be seen has the pleated fabric 9 two fold areas 90a . 90b each with several pleats 91 and between the fold areas 90a . 90b an approximately z-shaped transition region 92 with preferably vertically (vertically) extending intermediate leg and at each end a fastening region as a folded tissue-free end 92a . 92b on, over a in the example U-shaped fold section 93a . 93b in the adjacent fold area 90a . 90b passes.

With out of the 3 to 5 recognizable is the pleated fabric 9 on rubber-elastic drawstrings 13 ( 4 and 5 ) guided and / or held, in turn, on opposite end strips 14 . 15 are fixed and with spaced, parallel Zugschnurabschnitten 13a between the end strips 14 . 15 run. The end rails 14 . 15 are each in the assembled state of a rail 14a . 15a and a last bar 14b . 15b composed. With these drawstring sections 13a are the rubber-elastic pull cords 13 by corresponding, in each case aligned openings 16 ( 2 ) in the area of the individual pleats 91 of pleated fabric 9 guided.

In the assembled state sit the end strips 14 . 15 in the moldings 8a . 8b the pleated cassette 8th one. This forms the upper end bar in the figures 14 almost a pull bar, which over the first profile strip 8a with the lower roller shutter end bar 3 ' connected is. The other end bar 15 forms a kind of fixing strip, which over the second, lower profiled strip 8b the pleated cassette 8th at the lower end or in the lower area on or in the Rollpanzerschienen 6 is fixed.

When mounting the roller shutter curtain 2 and consequently the automatic mounting of the roller shutter curtain 2 held pleated fabric 9 with corresponding vertical movement only the first, upper profile strip 8a the pleated cassette 8th become the rubber-elastic drawstrings 13 elastically biased.

When lowering or lowering (closing) the roller shutter curtain 2 pull the rubber-elastic drawstrings 13 practically complete in the 5 shown relaxed state together. There are therefore no loose lacing sections or loops available, made of pleated fabric 9 could protrude and pleated tissue folded 9 in the pleated cassette 8th would have to be accommodated. In addition, the risk of entanglement of such a loop loop is reliably prevented within the pleated cassette.

As in 5 can be seen, are several rubber-elastic pull cords 13 provided, whose laces ends at certain, in 5 recognizable positions on the pleated fabric 9 facing away strip side of each end bar 14 . 15 looped around a support or guide ring 17 are laid, which in turn of a lace section 13a is interspersed. Pulleys or rings 18 allow a low-friction sliding as possible the rubber-elastic drawstrings 13 inside the pleated cassette 8th and there within the respective profile strip 8a . 8b ,

6 shows in perspective end view one of the preferably identical profile strips 8a . 8b the pleated cassette 8th , The profile bar 8a . 8b has a receiving chamber 19 and in profile transverse direction Q adjacent thereto a half-chamber 20 on. The reception chamber 19 and the half chamber 20 are over an intermediate wall 21 separated, in which a profile in the longitudinal direction L extending profile longitudinal slot 22 is introduced. The half chamber 20 serves to accommodate the corresponding fold area 90a . 90b with about half the number of pleats 91 of pleated fabric 9 , The other fold area 90b respectively. 90a of pleated fabric 9 is then in the half chamber 20 the other profile strip 8b respectively. 8a ,

As in connection with the 3a and 3b is recognizable, is the respective Endleiste 14 . 15 in the receiving chamber 19 the respective profile strip 8b . 8b used. When the respective tissue-free in the folded attachment area 92a . 92b of pleated fabric 9 at the corresponding end bar 14 . 15 is fixed, the corresponding arrangement is in the chambers 19 . 20 the profile strips 8a and 8b pushed in profile longitudinal L. This is the U-shaped fold section 93a . 93b of pleated fabric 9 in the profile longitudinal slot 22 guided.

The 7a and 7b show in perspective end view of the protective device with a view of one of the respective profile strip 8a . 8b the pleated cassette 8th associated cover parts 24 . 25 , The cover parts 24 . 25 each have a sliding pin 26 on, in the profile longitudinal direction L on the front sides of the moldings 8a . 8b extends out and in the assembled state in a corresponding, in the typical roller armor rail 6 usually already present guide groove or chamber 27 is seated and guided there in vertical and rail longitudinal direction S.

The respective cover part 24 . 25 is by means of a screw 28 on the corresponding profile strip 8a . 8b schraubbefestigt. The respective cover part 24 . 25 also has one for the sliding peg 26 spaced bearing and / or Gleitschenkel 29 on. This serves for pivotal mounting of Spreizbolzens 11 that is in the gap 30 between the sliding pin 26 and the bearing leg 29 extends into it. The depository 31 is located on the frontal free end of the corresponding cover 24 . 25 , It can be seen that only the profile strip 8b , which serves as a fixing strip end bar 15 receives, preferably on both sides, ie at both ends of such a Spreizbolzens (clamping bolt) 11 having.

Counter to Spreizbolzens 11 extends a mounting screw 32 , between the screw shaft 32a on the one hand and the expansion bolt 11 on the other hand, a widening in the profile longitudinal direction L, V-shaped or wedge-shaped expansion opening 33 is formed. The mounting screw 32 has a screw head 32b with, for example, a hexagon socket.

In the course of screwing mounting screw 32 , which for this purpose in an internal thread opening of the expansion bolt 11 is joined with this is the expansion bolt 11 at the depository 31 in profile transverse direction Q outward against the facing inner wall 6a the rolling armor rail 6 with simultaneous abutment of the shaft end 32c the mounting screw 32 on the opposite inner wall 6b the rolling armor rail 6 guided. In the course of a further screw connection becomes a reliable, releasable clamping fixation of the lower profiled strip 8b over its cover 25 produced. This clamping fixation is suitably carried out by means of opposing expansion bolts 11 and mounting screws 32 on both ends of the lower profile strip 8b the pleated cassette 8th ,

The pleated cassette 8th , Preferably the roller shutter end bar 3 ' facing profile strip 8a also has a joining chamber extending in the profile longitudinal direction L. 34 with a joining slot 35 over which the on the roller shutter end bar 3 ' fastened and fastened in the mounting state holding elements 5 in the joining chamber 34 can be used.
