Description

The invention relates to a shading device with an expandable fabric and at least one lateral profiled guide bar, in which the fabric or a projection bar attached to the fabric is guided in a displaceable manner, the profiled guide bar being attachable to a supporting structure via at least one holder, which is connected to the profiled guide bar via at least one engagement device is engaged, wherein the engagement device has at least one latching element which is formed on the holder and in a latching position engages behind a projection of the profiled guide strip, and wherein a blocking element is provided which can be brought into a blocking position in which it locks the latching element in its latched position .

A corresponding shading device can be, for example, a vertical awning, which will be used as an example in the following.

A corresponding vertical awning has a cloth that can be wound up on an upper cloth shaft and unwound from the cloth shaft. At the lower free end of the cloth a projection rod is arranged, which is guided with its axial ends in each case in a profiled guide strip during its vertical adjustment movement. The guide profile bar must be attached to a supporting structure, which can be, for example, a building wall. To attach the profiled guide rail to the building wall, it is known to screw several bolt-shaped holders to the building wall, which each extend essentially perpendicularly to the building wall and carry a clamping device in the form of a so-called slot nut at its free end. Since the guide rail must be attached to the building wall using these brackets, it is necessary to thread the sliding blocks into the guide rail, then fix the guide rail in the desired vertical position and tighten the sliding blocks or clamping devices to fix the guide rail. This procedure not only requires a large installation space, but is also tedious and it usually requires at least two people to attach the profiled guide rail.

From the DE 10 2010 052 365 A1 , From which is assumed in the preamble of claim 1, it is known to put a holder on a substructure, which has several locking elements. A guide profile is placed on the locking elements in such a way that the locking elements engage behind a wall of the guide profile. In this latched position, locking screws are screwed in, which spread the latching elements and hold them in their latched position. Screwing in the locking screws requires that an operator with a tool must have access to the screw head of the locking screws in order to screw them in be able. Depending on the structural conditions at the installation site, this can be difficult or even impossible.

The invention is based on the object of creating a shading device of the type mentioned, in which the guide profile strip can be attached to a supporting structure and in particular a building wall in a simple manner and quickly.

According to the invention, this object is achieved by a shading device having the features of claim 1 . It is also provided that the engagement device has at least one latching element which is formed on the holder and in a latching position engages behind a projection of the profiled guide strip. In addition, a locking element is provided which can be brought into a locking position in which it locks the locking element in its locking position.

It is provided that the holder has at least two spaced apart latching elements between which an intermediate space is formed. The blocking element is inserted at least in sections into the intermediate space, so that the blocking element prevents the latching elements from moving towards one another. The blocking element is preferably pushed linearly into the gap, which the user can do with his hands alone, without the need for a tool.

In order to prevent the blocking element from becoming detached from its blocking position over time, for example as a result of vibrations, the invention provides that the blocking element is in its blocking position with the latching element or latching elements and/or with the profiled guide strip is positively engaged and in particular is locked.

In a possible embodiment of the invention, it can be provided that the latching element is a latching finger which is connected in one piece to a base part of the holder and protrudes freely from the base part. The latching finger can be designed as a cantilevered, freely projecting rod, but it is also possible for the latching finger to have a lamellar or wall-like design, with the lamellar or wall-like latching finger being connected on one side in one piece to the base part of the holder and from this cantilevers freely.

For latching, the blocking element can have latching projections which each engage in a latching recess of the latching elements or the latching fingers. In kinematic reversal, the latching projections can also be formed on the latching elements or the latching fingers and the latching recesses on the blocking element. In a preferred embodiment of the invention, it is provided that the clamping finger has latching projections or latching recesses on its outside, which can be brought into latching engagement with corresponding latching recesses or latching projections of the latching elements arranged in the intermediate space.

As an alternative or in addition to this, provision can be made for the blocking element to be latched to the profiled guide strip in order to hold it in its blocking position.

In a possible embodiment of the invention it can be provided that the base part of the blocking element is designed in the shape of a cap and rests on an attachment of the profiled guide strip can be placed and locked with it in such a way that the locking finger is held in the gap.

According to the invention, at least one and in particular several holders are attached directly or indirectly to the supporting structure or building wall and in particular screwed on to attach the profiled guide strip. Several holders can be arranged at a distance in a row, but alternatively it is also possible for the holder to be in the form of a rod or rail and to carry several locking elements arranged at a distance, so that only a single holder is necessary for the profiled guide strip.

After the holder is attached directly or indirectly to the support structure, the profiled guide bar can be placed on the holder, with the latching element of the holder engaging behind the projection of the profiled guide bar and thereby already holding the profiled guide bar at least temporarily. In order to prevent the locking element from being released from its locking position, the blocking element is then brought into its locking position, in which it locks the locking element in its locking position, preferably in a form-fitting manner.

The holder with the locking element and the locking element are preferably made of plastic and can be designed as separate components that are assembled during assembly. However, the holder and the latching element are preferably designed as a one-piece, monolithic component. The blocking element is preferably a separate component that is independent of it, but the blocking element can also be integrated into the holder and arranged on the holder and can be adjusted between the blocked position and a release position be by shifting it linearly, for example.

The locking element preferably has a hook part which can be brought into engagement with the projection of the profile strip. The hook part is preferably connected in one piece and monolithically to the latching finger and, in particular, is arranged or formed on the free end of the latching finger. When two spaced latching fingers are provided, the hook portions preferably face opposite directions, i.e. away from the space formed between the latching fingers.

The blocking element preferably has a base part, for example in the form of a plate, and a blocking finger, which is preferably connected in one piece to the base part and is in contact with the latching element. The shape of the locking finger is adapted to the shape of the latching element or latching elements. If the latching elements are formed by lamellar or wall-like latching fingers, the locking finger also has a corresponding configuration so that it can be inserted into the space formed between the latching fingers and securely holds the latching fingers in their latching position.

In an alternative embodiment of the blocking element, it can be provided that the blocking element has a cap-shaped configuration in which, for example, a side wall that extends essentially perpendicularly to the base part is formed on at least two opposite side edges of the base part, which side wall preferably runs parallel and at a distance from the blocking finger . Each side wall can have a front end facing away from the base part wear locking protrusion. The cap-shaped configuration of the blocking element makes it possible to place the blocking element, for example, on an attachment of the profiled guide strip in such a way that the attachment is gripped. The attachment of the profiled guide strip preferably carries latching projections on an outside, which engage with the latching projections of the side walls.

In a preferred embodiment of the invention, it is provided that the holder and in particular the base part of the holder has a plate-shaped shoulder which is arranged between the profiled guide strip and the supporting structure when the holder is installed and can in particular be clamped. On the one hand, the shoulder serves to stabilize the holder and, on the other hand, prevents the profiled guide strip from being in direct contact with the supporting structure, which is particularly important when the two components are made of different metals.

In a preferred embodiment of the invention, it can be provided that the blocking element in its blocking position reaches through an opening in the profiled guide strip. In this case, the blocking element can be guided and positioned via positioning ribs formed on it in or on the opening in the profiled guide strip. On the one hand, this ensures easy insertion of the blocking element and stabilizes the blocking element in the inserted state, i.e. in its blocking position.

The blocking element can have projections and/or openings that enable a user to move the blocking element from the blocking position to the release position, which is necessary, for example, when the profiled guide bar is to be dismantled.

In a preferred embodiment of the invention, it is provided that the holder and/or the blocking element are at least partially arranged in a chamber within the profiled guide strip. For this purpose, the profiled guide strip is designed as a hollow profile, at least in sections, and has the chamber, which has an access opening on its side facing the supporting structure, through which the holder can be inserted, at least with its locking elements, into the chamber when the profiled guide strip is placed on the holder. The projections behind which the latching elements engage are also preferably formed in the chamber.

The opening through which the blocking element is inserted at least in sections into the chamber in order to engage with the blocking elements of the holder is preferably also formed in the wall of the chamber.

The arrangement of the holder and/or the blocking element within the chamber of the profiled guide strip has the advantage that the holder and the blocking element are protected from external influences and in particular the effects of the weather. In addition, they are not visible to an observer from the outside, which has aesthetic advantages.

The holder or holders can be attached directly to the supporting structure, for example a building wall, by means of suitable fastening elements. Alternatively, it can be provided according to the invention that several holders and preferably all holders on a support bar by means of suitable Fastening elements are attached, for example by means of fastening screws. The support strip with the holders can be prefabricated and can then be attached to the supporting structure at the installation site by means of suitable fastening elements, in particular fastening screws. In its installed state, the profiled guide strip is preferably supported on the support strip.

For aesthetic reasons, it is preferred that the dimensions of the support bar are selected so that when assembled it does not protrude laterally beyond the profiled guide bar and, in particular, that there is a smooth transition between the outer surface of the support bar and the outer surface of the profiled guide bar.

1 shows a schematic representation of the essential elements of a shading device 10 in the form of a vertical awning with a stretchable cloth 11, at the lower end of which is attached a projection rod 12, which is guided with its axial ends in lateral, vertical guide profile strips 13 during vertical adjustment.

The guide rail 13 according to 2 is designed as an extruded profile and attached to a support structure 15, for example in the form of a building wall. For this purpose, several holders 16 are provided, one of which in the Figures 3 and 4 is shown. The holder 16 has a block-shaped base part 17 in which two bores 18 are formed through which in 3 only schematically indicated fastening screws 28 can be passed, with which the holder 16 is attached to the supporting structure 15.

An engagement device 19 is formed on the base part 17 in the middle region of the base part 17 between the two bores 18 . The engagement device 19 comprises two locking elements 20 which are integral and monolithic with the Base 17 are connected and spaced apart parallel to each other and freely cantilevered from the base 17 according 3 extend upwards. Each latching element 20 is designed as an elastically deformable latching finger 30, the latching fingers 30 being designed like lamellae or walls in the exemplary embodiment shown. A hook part 21 is formed on the free end region of the locking fingers 30 facing away from the base part 17, the hook parts 21 of the two locking fingers 30 facing away from one another, ie being aligned on opposite sides. A gap 22 is formed between the two locking fingers 30 .

A plate-shaped shoulder 31 is formed on opposite sides of the base part 17 and extends over the entire length of the base part 17 .

To mount the profiled guide strip 13 on the supporting structure 15, a plurality of holders 16 are preferably mounted on the surface of the supporting structure 15 by means of the fastening screws 18. The profiled guide strip 13 is then placed on the holder 16 . The guide rail 13 has an inner chamber 36 with an access opening 37 formed in an outer wall of the guide rail 13 . Projections 29 are formed inside the chamber 36 and can engage with the hook parts 21 of the locking fingers 30 of the holder 16 .

The profiled guide strip 13 is placed on the holder 16 in such a way that the holder 16 is inserted through the access opening 37 into the interior of the chamber 36 until the hook parts 21 of the latching fingers 30 engage behind the projections 29 of the profiled guide strip 13 . The holder 16 is on this way in its detent position. This state is in 2 shown. The profiled guide strip 13 is at least provisionally mounted on the holder 16 as a result of this latching. In this state, the plate-shaped shoulders 31 are arranged between the outer surface of the profiled guide strip 13 and the outer surface of the supporting structure 15 and are clamped between the components mentioned.

To lock the holder 16 in its locked position, a locking element 23 is provided in the Figures 5 and 6 is shown in detail. In the exemplary embodiment shown, the blocking element 23 has a plate-shaped base part 24 and a blocking finger 25 that runs perpendicular thereto and is also plate-shaped, so that the blocking part 23 has a T-shaped cross section. On the outer surface of the locking finger 25 locking projections 33 are formed. Furthermore, 25 positioning ribs 26 are formed on the locking finger.

As 2 shows, an opening 32 is formed in a wall of the profiled guide strip 13 near the free ends of the latching fingers 30, through which the locking element 23 can be inserted with its locking finger 25 into the chamber 36 of the profiled guide strip 13 and preferably linearly pushed in such that the locking finger 25 enters the space 22 between the two latching fingers 30 and thereby spreads the latching fingers 30 and clamps the hook parts 21 against the projections 29 of the profiled guide strip 13 .

On the inner sides of the locking fingers 30 facing one another, there is a locking recess 34 which engages with the locking projections 33 on the locking finger 25 of the locking part 23 in Engagement occurs, so that the locking part 23 in its inserted, in 7 shown locked position with the locking fingers 30 is locked.

The positioning ribs 26 formed on the locking finger 25 serve to hold the locking element 32 in an exact position within the opening 32 . When the locking element 23 is in the locking position, its positioning ribs 26 rest against the wall of the chamber 36 on the outside in the area of the opening 32, as shown in FIG 7 is shown.

8 shows one 2 corresponding sectional view and differs from the embodiment according to 2 characterized in that the profiled guide bar 13 is not attached directly to the support structure 15, but that between the profiled guide bar 13 and the support structure 15 a support bar 35 is arranged, which preferably consists of plastic or metal.

Several similar holders 16 are preferably attached in a row to the support strip 35 by means of the fastening screws 28 . The support strip 35 with the holders 16 can be prefabricated. At the place of installation, the support bar 35 with the holders 16 is attached to the supporting structure in the desired alignment by means of further fastening elements (not shown). In this way it is ensured that the holders 16 assume a desired position relative to one another, as a result of which the attachment of the profiled guide strip 13 is simplified.

9 shows an alternative embodiment of the locking element 23, the design of which differs from the design according to the Figures 5 and 6 differs in that at At least two opposite side edges of the base part 24 are each formed with a side wall 39 which extends perpendicularly to the base part 24 and runs parallel to and at a distance from the locking finger 25 . Each side wall 39 has a locking projection 40 on its front end facing away from the base part 24.

The cap-shaped configuration of the blocking element 23 formed in this way makes it possible to place the blocking element 23 on an attachment 38 of the profiled guide strip 13 . The projection 38 carries latching projections 41 on its outside, behind which the latching projections 40 of the side walls 39 engage. In this way, the locking element in the in figure 9 locked position shown locked with the profiled guide bar 13.
