Description

The invention relates to a pleated blind.

The Plisseejalousie is intended for a window or a door, which under window or door in a broad sense, all comparable objects, including, for example, non-obvious elements understood. The pleated blind is used, for example, as a privacy screen, glare protection, insect screen and / or for darkening.

The cover of the window or the door through the pleated blind is adjustable by a user. For this purpose, the pleated blind has an extensible and collapsible, multiply pleated and in particular a plurality of substantially parallel folds exhibiting fabric. The fabric may be designed in particular as a pleated fly screen. The setting of the cover is done by moving and / or pulling apart or pushing together of this sheet.

In order to avoid tilting of the fabric when pulling apart or pushing together of this sheet or to guarantee a defined movement of the sheet, this is guided in guide rails which are mounted on a door or window frame. The length of the guide rails must generally be adapted to the size of the door or window frame.

Especially with pleated blinds, which are intended for insect protection, typically only a temporary attachment of the pleated blind on the door or window frame is provided.

The invention has for its object to provide a new Plisseejalousie, which is characterized by a quick and easy installation to door and / or window frames with different sizes.

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

The pleated blind according to the invention for a window or a door comprises an extensible and collapsible, multiply pleated and in particular a plurality of substantially parallel folds exhibiting sheet, at least one end strip arranged on the sheet and two parallel to each other and perpendicular to the at least one end strip extending, Attachable to a window or door, telescopic guide rails. The at least one end strip is at least partially displaceably guided along the telescoping guide rails in the longitudinal direction and each telescoping guide rail comprises at least two, mutually longitudinally displaceable and spring-loaded in the longitudinal direction biased guide rails.

Since the guide rails are telescopic, it is ensured that the pleated blind can be attached to door and / or window frames of different sizes. In addition, the at least two mutually displaceable guide rails of each guide rail are biased against each spring-loaded, so that the telescopic guide rail can be clamped non-positively in a door or window frame in a particularly simple manner. Use of adhesive agents such as adhesives, adhesive strips or the like can thus be avoided.

The at least one end strip is formed, for example, as piping or piping rail. The fabric can be made in a conventional manner from different textile materials. In a preferred embodiment, the fabric is designed as a fly screen for insect protection.

For non-positive fixation of the pleated blind, fastening elements, in particular fastening clamps or hooks, are arranged in each case on the end of each telescoping guide rail for engagement in a window or door frame. Preferably, the fastening elements are pivotable over an angular range in order to further facilitate the engagement in differently shaped frames.

In an embodiment, the at least two guide rails of each guide rail are biased spring-loaded by means of a gas spring from each other in the longitudinal direction. The guide rails of each guide rail are displaceable against each other and against the force exerted by the spring means or the gas pressure spring at least over a longitudinal section by a force exerted by the user, so that the guide rails, in particular with the fasteners fastened thereto at the end, engage the door handle. and / or window frames can be brought. The fixing of the guide rails on the door and / or window frame is non-positively by the mediated by the spring means or the gas spring, axially effective spring force.

In an embodiment, the at least two guide rails of each guide rail extend transversely to the longitudinal direction, essentially U-shaped cross-sectional profile on. The guide rails are inserted into each other and slidable in the longitudinal direction. In a direction extending transversely to the longitudinal direction, a relative movement of the guide strips to each other, in particular by a corresponding shaping of the cross-sectional profiles or the provision of correspondingly shaped form-locking elements in the cross-sectional profile, such as a groove, in which engage one or more projections, inhibited or prevented to facilitate the assembly.

The at least two guide strips, in particular as inner and outer guide strips, are preferably inserted into one another such that the guide rail formed by the at least two guide strips has an open side for guiding the end strip and / or the fabric. At least one particular edge-side portion of the end strip or of the sheet engages in the open side of the guide rail, so that a reliable guidance of the sheet is ensured when this is adjusted by the user, in particular apart or contracted.

Preferably, the inner guide rail on support webs for guiding the end strip and / or the fabric. A bridging rail, which terminates flush with the support webs, extending at least over a longitudinal portion of the inner and outer guide bar, in which the inner guide rail is inserted. The support webs and / or the bridging rail serve to further improve the guidance of the fabric in the guide rail and in particular to counteract catching. The supporting webs are provided in an embodiment to separate a space within the guide rail, in which in particular the spring means, such as the aforementioned gas spring, is mounted from a space which serves to guide the end strip and / or the fabric. Since, in the mounted state, the outer guide rail is generally displaced at least slightly relative to the inner guide rail, the support webs of the inner guide rail may not extend in the longitudinal direction over the axial length of the telescopic guide rail, which is relevant to the guidance of the fabric. In the transition region between the inner and the outer guide rail, therefore, the bridging rail, which is flush with the support bars, provided in order to avoid in particular a hooking of the fabric in this area.

For example, the bridging rail is supported on an end piece for fixing a spring means and / or on the spring means, in particular on a cylinder of the gas spring.

In an embodiment, the sheet is arranged between two mutually parallel end strips. For example, the end strips are attached to the top and bottom of the fabric, i. The sheet can be pulled apart or pushed together in the vertical direction. But it is also possible, for example, that the fabric can be pushed apart or pushed together in the horizontal direction, that is, the end strips are attached to the left and right of the fabric. In the former case, the guide rails are arranged vertically, in the second case horizontal.

To further improve the guide along the telescoping guide rails is provided in an embodiment to provide the end at least one end strip in each case with resilient retaining elements. The resilient retaining elements may for example be formed substantially as tabs, and are guided displaceably in the guide rails. The resilient retaining elements are in particular designed to bear against the inside of the guide rail under friction during the guidance of the end strip or of the sheet attached thereto.

In a further development, it is provided to form the retaining elements for the frictional fixing of the at least one end strip along the guide rails. In this case, the spring force provided by the resilient retaining elements is preferably dimensioned such that the static friction mediated on the inside of the guide rail is sufficient to fix the end strip at arbitrary positions along the guide rail, optionally against gravity or a restoring force mediated by the fabric. Such embodiments are preferred because a user-side lock, for example, using a locking pin or pin or the like, can be omitted.

In an embodiment end caps are arranged on each guide rail end, in particular opposite, having latching elements. The latching elements have a shape complementary to the holding elements. The locking elements and the holding elements are adapted to fix the at least one end strip in a predetermined, in particular end, position by positive engagement. For this purpose, the retaining elements of the end strips engage in the locking elements. In an embodiment, the guide provided by the guide rail extends into the end caps. As locking elements can in particular serve latching projections in the guide, temporarily fix the end strips temporarily in end positions, for example in an upper or lower end position.

In a further development end caps are provided with a plurality of spaced apart longitudinally locking elements. In this way it is possible to fix the end strip with the attached sheet at different positions by snapping.

1 shows one at a window 3 mounted pleated blind 1 according to the invention. The pleated blind 1 comprises an extensible and collapsible, multiply pleated and thus a plurality of substantially parallel folds 16 exhibiting sheet 2 , which is formed for example from a fly screen. Top and bottom of the fabric 2 is each a closing bar 5 (also: piping, Kederleiste) provided, which parallel to the folds 16 of the fabric 2 is aligned and thus horizontally or horizontally. In 1 is just the top end bar 5 shown in an upper position O , is locked.

Furthermore, the Plisseejalousie 1 two parallel to each other and perpendicular to the folds 16 of the fabric 2 at the window 3 attached guide rails 6 on that on a frame 4 of the window 3 are firmly attached. For frictional attachment to the frame 4 are the guide rails 6 telescopic, ie in the longitudinal direction L formed variable in length. In addition, the guide rail 6 longitudinal L spring-loaded biased, so that these frictionally in the frame 4 is clamped. For fastening the guide rails 6 are end caps on each end 7 with fastening elements designed as fastening hooks 8th attached to the frame 4 of the window 3 intervention. The one in the longitudinal direction L effective traction is provided by a telescopic guide rail 6 arranged spring means 18 causes.

The end strips 5 and the sheet associated therewith 2 are along the telescopic guide rails 6 longitudinal L guided. For this purpose, there is in each case an end-side or edge-side section of the end strips 5 and the fabric 2 in a guided tour F the laterally arranged guide rails 6 , such as in 2 shown, recorded. At the in 1 illustrated upper end bar 5 is also a handle 15 provided for locking and unlocking the horizontally extending upper end bar 5 in the upper position O serves.

2 shows details of attaching the top end bar 5 in the upper position O in a sectional view. One from the guide bar 6 provided guidance F extends into the area of the end cap 7 into it. Within the leadership F or the guide rail 6 is a marginal section of the end bar 5 slidably guided. This section of the end bar 5 has a resilient retaining element 9 on, which is designed approximately tab-shaped and when moving the end strip 5 along the guide rail 6 attached to this. The frictional engagement between the guide rail 6 and holding element 9 is typically already sufficient, at least the horizontal running end bar 5 at any position along the guide rail 6 to fix. At the top position O is a locking element 10 provided to the end bar 5 to lock. The fixation of the end bar 5 in the upper position O with increased holding force is effected by a between the holding element 9 and the locking element 10 mediated fit. This serves, in particular, to ensure that the fabric is also pulled apart 2 is made possible against a restoring force possibly caused by the pleating. The locking element 10 is constructed in the illustrated embodiment as a latching projection, which is a holding element 9 has corresponding shaping and in the leadership F protrudes. For locking the end bar 5 in the upper position O just becomes the end bar 5 longitudinal L shifted by the user up and under exercise of force on the locking element 10 spent so that the retaining element 9 in the in 2 shown upper position O locks. Unlocking takes place by a corresponding movement in the opposite direction. The holding element 9 is resilient and can be at least slightly in a transverse to the end strip 5 deflecting direction.

3 shows a cross-sectional profile of the guide rail 6 transverse to the longitudinal direction L , In the illustrated embodiment, the telescopic guide rail comprises 6 two to each other in the longitudinal direction L , ie perpendicular to the illustrated plane, sliding guide rails 11 . 12 , The guide rails 11 . 12 are inserted into each other and have substantially U-shaped cross-sectional profiles. The open sides of the U-shaped guide rails 11 . 12 point to the same page, so there's the end bar 5 with the holding element 9 or the fabric 2 can be introduced.

For linear guidance of the guide rails 11 . 12 in the longitudinal direction are on the inner guide rail 11 laterally protruding and opposite projections 14 provided in correspondingly formed grooves 17 intervention.

The inner guide rail 10 has inwardly directed support webs 13 on that leading to the end bar 5 or of the fabric 2 serve. In particular, the support bars border 13 one to guide the end bar 5 or of the fabric 2 provided area of an inner portion of the guide rail 6 from, in the final assembled state, a spring means 18 , In particular, a gas spring is arranged.

4 shows that in the guide rail 6 arranged spring means 18 in a perspective view. The spring means is formed in a conventional manner as a pneumatic spring or gas pressure spring and comprises a piston 19 in a cylinder 20 is movably guided. In the cylinder 20 is a gas, especially stored under pressure. During a movement of the piston 19 in the cylinder 20 inside, the gas inside the cylinder 20 compressed, so that a corresponding opposing restoring force is generated.

Each end of the spring means 18 or on the gas spring are end pieces 21 . 22 by means of three screws each 23 attached. The first tail 21 is at the end of the piston 19 attached and used to attach the inner guide rail 11 , The first tail 21 has a trapezoidal cross-sectional profile, the form-fitting in the final assembled state to that of the support webs 13 delimited inner area of the inner guide rail 11 is applied. This is in detail in 5 shown.

How out 4 As can be seen, the second tail is 22 on the cylinder 20 attached to the gas spring. The second tail 22 has a substantially rectangular cross-sectional profile, which is the embodiment of the outer guide rail 12 equivalent. Like, for example 6 can be seen, lies the second end piece 22 in the final assembled state on the inside of the outer guide strip 12 on. For this purpose, the second tail 22 further, laterally protruding projections 24 on, in correspondingly shaped further grooves 25 (see. 4 ) of the outer guide rail 12 (see. 3 ) intervene.

How out 6 Obviously, the tails support themselves 21 . 22 longitudinal L each at the end of the guide rail 6 attached end caps 7 from.

From the exploded view of 7 it turns out that the end caps 7 are two-piece. A first end cap part 26 has slots 28 in particular for the pivotable guidance of the fastening element 8th in the final assembled state. The first end cap element 26 is by means of three screw connections with a second end cap element 27 connectable. These are on the first and second end cap element 26 . 27 corresponding screw guides 29 intended.

For end attachment of the end cap 7 on the guide rail 6 have the end cap elements 26 . 27 fixing portions 30 . 31 on, which are provided in the assembled state to, in the inner and outer guide rail 11 . 12 to be plugged. The cross-sectional profile of the attachment sections 30 . 31 thus correspond to the shape of the inner and outer guide rail 11 . 12 , In 7 is an example of an end cap 7 for attachment to the inner guide rail 11 shown. The exemplary illustrated fastening sections 30 . 31 have in the assembled state a trapezoidal cross-sectional profile, which is designed to be in the inner guide bar 11 to be used at the end.

How out 6 can be seen, is in the transition region between the outer guide rail 12 and inner guide bar 11 a bridging rail 32 arranged, which are flush with the support webs 13 closes and a snagging in the guide rails 6 led end bar 5 or the fabric attached thereto 2 should prevent.

The bridging rail 32 supports, as in 8th and 9 shown both on the cylinder 20 of the spring means 18 , as well as at the tail 22 from. For supporting on the cylinder 20 has the bridging rail 32 cup-shaped support elements 33 on.

10 schematically illustrates the attachment of the pleated blind 1 at the window 3 according to a preferred variant. The pleated blind 1 is via the telescopic guide rails 6 at the frame 4 of the window 3 attached. The spring means 18 causes the inner and outer guide bar 11 . 12 against each other in the longitudinal direction L are resiliently biased. When inserting the fastener 8th in the frame 4 become the guide rails 11 . 12 slightly shifted against each other, leaving the inside of the guide rail 6 arranged spring means 18 exerts a restoring force. This will be the guide rails 6 at the frame 4 fixed non-positively. The guide rail is preferred 6 with its outer guide rail 12 mounted upwards so that water can drain better.
