This means that the mullion and transom construction (1) can also be produced with a narrow face width when using sun protection. The invention also relates to a method for assembling a cassette (3) with a rollable curtain (5) on a post-and-bar construction (1).

Description

The present invention relates to a post-and-bar construction with two posts, between which at least one bar is arranged, with a rollable curtain, in particular a cassette with a rollable curtain being fixed to the at least one bar, which is between a position wound around a winding shaft and a developed position arranged downwards parallel to a filling element is movable and a method for assembling a cassette with a rollable hanging on a post-and-beam construction.

The EP 2 754 843 A2 discloses a mounting arrangement for a sun protection which can be mounted on a window or a door via a support profile. The carrier profile is fixed to the underside of a frame and can thus shade a filling element such as an insulating glass pane. This construction has proven itself particularly for slat curtains that are guided along a tensioning cable attached to a tensioning profile. In the case of a post-and-rail construction, such a carrier profile for sun protection can be fixed to the underside of a rail, in which case the view width is increased, which is visually disadvantageous. In addition, assembly is time-consuming, since the individual parts of the sun protection must be aligned and connected on the construction site.

It is therefore the object of the present invention to create a post-and-beam construction which, with a compact design, enables the arrangement of a curtain for sun protection. In addition, a method for assembling a cassette with a rollable curtain on a post-and-beam construction is to be provided, which enables an effective assembly of the cassette.

This object is achieved with a mullion and transom construction with the features of claim 1 and a method with the features of claim 17.

In the post-and-bar construction according to the invention, the at least one bar has a downwardly open receptacle in which a curtain is fixed in the rolled-up position, the curtain being movable between a rolled-up position and an unrolled position. The integration of the curtain in the rolled-up position in the transom enables a narrow face width and a compact structure. A hollow chamber in the form of the receptacle that is open at the bottom is used for the arrangement of the curtain, so that no protruding attachment or a support profile with the curtain is visible.

A cassette is preferably provided in which the rolled up curtain is arranged. Then the cassette and the curtain in the rolled-up position of the curtain are added in a horizontal view of the bolt within the height of the bolt. In other words, the cassette with the curtain does not protrude upwards or downwards over the bolt in the vertical direction, but is integrated into the bolt, in particular arranged flush with the surface.

The curtain is preferably pre-tensioned in the unwound direction via a drop bar. This means that very thin materials can also be used for the curtain, which are stretched by the weight of the drop rod. In addition, when attached to the outside, the curtain is also tensioned against wind loads.

The drop bar can be guided on opposite sides with a guide element in a groove-shaped guide. The guide element can be designed as an extension of the drop bar, for example as a pin or as a sliding element. The guide on the cassette is preferably designed as a curved guide with a curved guide section. The curved guide section can extend at least partially parallel to a circumferential direction of the winding shaft, so that the curtain is initially moved in the vertical direction during winding and is then moved inclined or curved to the vertical in order to avoid wrinkling on the curtain.

For a visually appealing appearance, the drop bar can be arranged in the rolled-up position of the curtain in such a way that an underside of the drop bar is arranged essentially flush with an underside of the bolt. As a result, it is not visible to the user that the curtain is arranged inside the bolt.

For an optimized guidance of the curtain during winding and unwinding, a groove-shaped guide for the drop bar can be formed on the two posts on the side facing one another. The drop bar can then engage in the groove-shaped guide with a guide element, in particular a guide pin. In addition, in the developed position, the curtain can be at least partially inserted with an edge in the groove-shaped guide, so that there are no slots through which sunlight can penetrate unfiltered. The drop bar can be fixed to the curtain in one or more parts.

The curtain is preferably designed as a flexible flat structure, for example as a roller blind, pleated or slat curtain. All materials that can be rolled up, such as lamellas, fabrics or foils, can be used that offer sun protection or a visually appealing appearance for indoor use.

In the assembled position, the cassette preferably has on an underside a cover which can be fixed to the bolt and which at least partially closes an underside of the cassette, preferably the area which is arranged adjacent to the drop bar in the wound position is closed. This results in a closed appearance on the underside of the bolt due to the flat underside of the bolt, the cover and the underside of the drop bar.

The post-and-bar construction according to the invention preferably comprises bars and / or posts which have an extruded profile made of aluminum. This allows high loads to be absorbed, so that even large surface elements can be covered with the curtain. The mullion and transom construction can also be designed as a frame, for example as a blind or casement frame in the form of a door or window, or as an element facade.

The curtain can be arranged on an outside of the filling element for optimized sun protection. The cassette can then be mounted on an outside of the bolt, for example on an attachment that is fixed to a pressure strip. The bolt is then formed in several parts and comprises a profile on the inside and an attachment part on the outside. Alternatively, in the unwound position, the curtain can also be attached to the inside of the Be arranged filling element. The cassette can then also be on the inside. Then the bolt can optionally be designed in one piece or in several pieces in order to form a receptacle that is open at the bottom.

According to a further post-and-bar construction according to the invention, the winding shaft can be rotated by an electric drive, a plug being provided on the cassette which is connected to a connector for the electrical power supply. The connecting plug can be provided on the post or bolt, so that when the cassette is being installed, the plug can be easily inserted or plugged into the connecting plug in order to provide a power supply. Such an insertion does not necessarily have to be carried out by an electrician, but can also be carried out by the metalworker who assembles the post-and-beam construction.

The plug is preferably arranged on an axial end face of the cassette. This allows the cassette to be mounted in or on the connector with a pivoting movement. The plug can be arranged at least partially protected within the winding shaft. The cassette can preferably be pretensioned towards the connecting plug via at least one spring element. The spring element can be provided on the side of the cassette opposite the plug, preferably on an end wall of the cassette. The spring element can be designed as a compression spring, for example as a leaf spring, helical spring or spring assembly.

In a preferred embodiment, the height of the cassette can be adjusted at least on one side by means of an adjusting device. This allows tolerances to be compensated for during assembly. The adjustment device comprises a holder which is fixed to one of the posts and on which an adjustment element is provided for moving an end wall of the cassette. The holder can be fixed to the post by means of fastening means, preferably a bolt or a screw inserted into an opening. As a result, a height adjustment between the holder and the cassette can be effected via an adjusting element, for example an adjusting screw, an eccentric or a worm.

A connecting piece for mounting the winding shaft is preferably fixed or integrally formed on the wall of the cassette. This allows over the nozzle a storage of the winding shaft take place, optionally as a plain bearing or with a roller bearing.

In a further embodiment, the electric drive is arranged in a protected manner within the winding shaft. A part of the electric drive can be held non-rotatably in the winding shaft via the plug, while a driven part of the drive rotates together with the winding shaft.

The connector is preferably fixed to a hollow chamber of one of the posts in which a line for the electrical power supply is laid. As a result, the electrical power supply, optionally also control lines, can be laid in a protected manner in the hollow chamber.

In a method according to the invention for assembling a cassette with a rollable curtain on a post-and-rail construction, a connector is first mounted on a post or a bolt of a post-and-rail construction. Then a plug on the cassette is connected to the connecting plug and the cassette is positioned and fixed on a bolt and / or post of the post-and-bolt construction.

A post-and-bar construction 1 comprises an upper horizontal bar 2 and a lower horizontal bar 8, which are arranged between two posts 10. The mullion and transom construction 1 can also be designed as a frame, for example as a blind or casement frame in the form of a door or a window, or as an element facade. The profiles of the bars 2 and 8 and the posts 10 can be made of aluminum, plastic, wood or a composite material.

The bolt 2 comprises a downwardly open receptacle with a cassette 3 on which a winding shaft 4 is rotatably mounted. A curtain 5, in particular made of a fabric, a pleated blind or another flexible material, is wound onto the winding shaft 4. The curtain 5 is connected on the underside with a drop rod 6, which pulls the curtain 5 downwards through its weight. The cassette 3 is closed on the underside by a cover 7 which is fixed to the bolt 2.

The post-and-bar construction 1 is used to fix filling elements 9, in particular insulating glass panes, but also other plate-shaped filling elements. The filling element 9 is held at the edge in the region of the bolt 2 on a seal 14 which is drawn into a groove in the bolt 2. The bolt 2 has a central screw groove 15 on the outside with a corrugation on the inside, into which screws 16 are screwed as fastening means. Furthermore, an insulating strip for thermal insulation can be fixed to the screw groove 15. A pressure strip 12 is fixed to the bolt 2 via the screws 16, on which sealing profiles 13 are drawn in on opposite sides of the screw 16, with a sealing profile 13 pressing on the outside against the filling element 9 in order to clamp it to the seal 14 on the bolt 2 to fix. On the opposite side of the screw 16, a spacer is arranged between the sealing profile 13 and the seal 14, with a further filling element 9 optionally there can be positioned. The pressure strip 12 is covered on the outside by a cover strip 24. In a horizontal view, therefore, only the cover strip 24 is visible from the outside and the end face of the bolt 2 is visible from the inside, but not the cassette 3 with the curtain 5 integrated in the bolt 2.

In Figure 2 a section through the two posts 10 which fix the filling element 9 at the edge is shown. For this purpose, screw grooves 15 with screws 16 are also provided in the posts 10 in order to fix a pressure strip 12 with sealing profiles 13 in a clamping manner on the filling element 9 or the spacer 17. A groove-shaped guide 11 is also provided on the post 10, which guide is not formed integrally with a profile of the post 10, but rather on a guide strip 19 which is mounted on the post 10. Optionally, the groove-shaped guide 11 can also be formed integrally with the post 10. The post 10 can also be formed in one or more parts.

A guide element 18 in the form of a pin, which is arranged on the drop bar 6, engages in the groove-shaped guide 11. As a result, the drop bar 6 is guided on opposite sides of the guide 11 in the vertical direction on the post 10.

In Figure 3 the bolt 2 with the cassette 3 is shown during assembly. The bolt 2 comprises a downwardly open receptacle 23 which is designed as an open hollow chamber into which the cassette 3 is inserted during assembly. The cassette 3 comprises walls 30 on opposite sides, on which the winding shaft 4 is rotatably mounted. The walls are inserted into the receptacle 23 and fixed there in a rotationally fixed manner, while the winding shaft 4 can be rotated via a drive (not shown), in particular a drive within the winding shaft 4. After the assembly of the cassette 3, the cover 7 is mounted on the bolt 2, a fastening groove 22 being formed integrally with the bolt 2 for this purpose, in which a pin 20 is fixed on the cover 7 with the interposition of a clamping element.

In the Figures 4A and 4B the drop bar 6 is shown in a raised position in which the curtain 5 is wound onto the winding shaft 4. An underside of the drop bar 6 is aligned flush with an underside of the bolt 2 and the cover 7 in the raised position. It can also be seen that the groove-shaped guide 11 is aligned vertically in the area of the post 10, but is not vertical in the area of the cassette, but as Curve guide 31 extends, which extends at least partially parallel to a circumference of the winding shaft 4. As a result, the drop bar 6 is not only moved vertically, but also horizontally away from an axis of rotation of the winding shaft 4 in the area of the cassette 3. This avoids kinking or folding of the curtain 5 when it is rolled up or pressure points due to the weight of the drop bar 6.

If the curtain 5 is now unwound, the guide element 18 moves along the curved guide 31 into the groove-shaped guide 11 on the post 10, as shown in FIG Figures 5A and 5B is shown. The drop rod 6 pulls the curtain 5 downwards and is moved in the area of the post 10 in the vertical direction. The guide elements 18 in the form of the pins engage in the groove-shaped guide 11, the curtain 5 also having a width that is at least as large as the distance between the two posts 10, preferably slightly larger, so that no slots between the curtain and the post 10 arise, which could allow unfiltered sunlight into the interior.

In the Figures 6A and 6B the post 10 is shown in detail. For mounting the filling element 9, the post 10 comprises a screw groove 15 on the outside and between the outside and an inside a guide strip 19 is mounted in a central area on one side and a cover strip 21 is mounted on the opposite side. The guide bar 19 has a groove-shaped guide 11 for the guide elements 18 and is mounted on the post 10 via a pin 20, which is inserted into a fastening groove 22 with the interposition of a clamping element. Optionally, the guide bar 19 can also be formed integrally with the post 10 or can be fixed to the post 10 via other fastening means. On the opposite side, a smooth surface is to be provided by the cover strip 21, which can also be mounted in the fastening groove 22 via a pin 20, so that the post 10 is symmetrical about a central vertical plane, both on the right and on the left side to guide the curtain 5 can be mounted.

In Figure 7 the guidance of the curtain 5 is shown with a modified bolt 2 ', which in the mounted position has a greater height H than the bolt 2 of the Figures 1 to 6 having. Therefore, a hollow chamber 20 'is also formed above the downwardly open receptacle, the bolt 2' otherwise being formed as in the first exemplary embodiment. It can be seen that a groove-shaped curved guide 31 is formed on the wall 30 of the cassette 3, which opens into the groove-shaped vertical guide 11 on the post 10 ', the post 10' also having a slightly greater width than the post 10. The groove-shaped guide 11 is at least partially bounded integrally by the post 10 ', and only a wall section is through a portion of a guide bar 19 'is formed which is fixed to the post 10'. In the shown wound position, an underside of the drop bar 6 is arranged essentially flush with the strip-shaped cover 7 and the underside of the bolt 2 '.

In Figure 8 a post-and-bar construction with the bolt 2 'is shown, in which the drop bar 6 has been moved slightly downwards so that part of the curtain 5 is visible, which engages the groove-shaped guide 11 on the post 10' at the edge. This avoids gaps between the curtain 5 and the post 10 'through which sunlight could penetrate unfiltered from the outside to the inside. A winding shaft 4 is also mounted on the lower bar 2 'of the post-and-bar construction, the drop bar 6 being shown in the raised position. There is a minimal gap between the cover 7 and the drop rod 6, which allows the drop rod 6 to move towards the inside along the curved guide 31. In the horizontal viewing direction, the cassette 3 with the curtain 5 is received completely within the contour of the bolt 2 '.

In the Figures 9 and 10 Another embodiment of a post-and-bar construction is shown, in which a filling element 9 is clampingly fixed to an upper bar 2 ″ via a pressure strip 12, as in the previous embodiment the pressure strip 12 is fixed, preferably by snapping on. A downwardly open receptacle is formed on the top 25 of the bolt 2 ″, into which the winding shaft 4 with the curtain 5 with the cassette 3 is inserted. The cassette 3 is closed on the underside by the cover 7, which is attached to a receptacle 23 of the attachment 25. The winding and unwinding of the curtain 5 takes place as in the previous exemplary embodiment, with the difference that the curtain 5 is not guided on an inside of the surface element 9, but on an outside.

In Figure 10 FIG. 10 is a section through the two posts 10 "of the post-and-beam construction of FIG Figure 9 shown. The posts 10 ″ serve, on the one hand, to fix the filling element 9 via pressure strips 12, and an attachment 40 is also mounted on the outside of the posts 10 ″, in particular by latching onto it the pressure bar 12. A guide bar 19 with a groove-shaped guide 11 is formed on the attachment 40, into which a guide element 18 engages, which is fixed to the drop bar 6. Each post 10 ″ thus comprises an attachment 40 on the outside for guiding the curtain 5 over the drop bar 6. Optionally, the guide bar 19 can also be formed integrally with the attachment 40.

In the Figures 11 and 12th Another embodiment of a post-and-bar construction is shown in which an attachment 26 with a downwardly open receptacle for a cassette 3, in which the winding shaft 4 with the curtain 5 is accommodated, is mounted on the bolt 2 '''. The bolt 2 '''fixes the filling element 9 on its outside via a pressure strip 12, as in the previous exemplary embodiment. In this exemplary embodiment, the curtain 5 is not guided directly adjacent to the filling element 9, as in FIG Figure 1 , but at a greater distance. The attachment 26 is fixed to the profile of the bolt 2 '''via clamping or latching means.

As in Figure 12 As shown, the post 10 ″ also has an attachment 41 on which a guide strip 19 with a groove-shaped guide 11 for the guide elements 18 on the drop bar 6 is provided. As a result, the curtain 5 can be guided at a greater distance from the filling element 9 .

The winding shaft 4 is preferably driven by an electric motor which is connected to a power supply when the cassette 3 is assembled. For this purpose, a plug can be formed on the cassette 3, which connector interacts with a connector on the bolt 2 or post 10, with the connector or connector optionally also being able to be configured as a socket. For the electrical power supply, an electrical cable or a control line can be guided in the post 10. For this shows Figure 13 an example in which a circular open receptacle for a cable 50, which is connected to a connector, is formed in a hollow chamber of the post 10.

In the embodiment of Figure 14 a receptacle 51 for a ribbon cable 52 is formed integrally with the post 10, which can be inserted into the groove or receptacle 51 in order to supply and / or control an electric drive.

Figure 15 FIG. 11 shows a section through a modified post 10 ″, which differs from FIG Figure 10 is connected to an additional attachment profile 43. The attachment profile 43 is fixed with a strip-shaped holder 42 via screws 44, which is plugged into or onto the screw groove 15 with a web. An optionally provided further screw groove 15 for connection to further components is provided on an outside of the attachment profile 43. The attachment profile 43 can alternatively also be latched or clamped to the post 10 ″ by pivoting or some other movement.

A cover strip 21 for forming a closed outer contour is fixed to the attachment profile 43 on one side and a guide strip 19 ′ is fixed on the opposite side in order to form a groove-shaped guide 11 for a guide element 18.

The above exemplary embodiments can be combined with one another. For example, in the case of a post-and-bar construction, the curtain 5 can optionally be guided on the outside or on the inside or in different positions on the inside. This means that the curtain can be positioned depending on the installation situation. In addition, the geometry of the individual profiles can be adapted to the requirements of the post-and-rail construction.

Figure 16 shows the post-and-bar construction 1 before the assembly of the cassette 3 on the bolt 2. On an end wall 28 on the cassette 3 there is an opening through which part of a plug 14 is visible. The front wall 28 with the plug 61 is now according to Figure 17 attached to the post 10 in order to bring the plug 61 into contact with a connector which is not visible here. For this purpose, the cassette 3 is pushed onto or into the connector in a combined sliding pivoting movement and then the cassette is pivoted to the underside of the bolt 2.

In the Figures 18A and 18B the mounted position of the cassette 3 is shown, the cassette 3 being essentially flush with a lower edge of the bolt 2 and thus not visible in a horizontal view. In the sectional view of the Figure 18B it can be seen that an end wall 30 is held on the post 10 in a height-adjustable manner with respect to the plug 61 via an adjusting device.

In the Figures 19A to 19D the wall 30 of the cassette 3 with the adjusting device is shown in detail. The wall 30 comprises a connecting piece 29 onto which the winding shaft 4 is slipped. The connecting piece 29 can form a rotary bearing for the winding shaft 4.

On the rear side of the wall 30, one or more spring elements 37, in particular leaf springs, are molded or formed, which preload the cassette 3 in the mounted position in the axial direction in order to ensure electrical contact with the plug 61.

Furthermore, a web 33 protrudes downward on the wall 30 and is guided in a channel 35 of a holder 32. A bolt 34 is provided on the holder 32 and can be inserted into an opening (not shown) in the post 10. The bolt 34 is used for positioning and fixing on the post 10.

In the in Figure 19B In the mounted position shown, the web 33 engages in the channel 35, with an internal thread for an adjusting element, in particular a screw 36, being provided in the holder 32 ( Figure 19C ). The screw 36, for example an Allen screw, can adjust the wall 30 relative to the holder 32 via the internal thread of the holder 32 at a stop.

In Figure 19D the adjustment device with the wall 30 is shown in a side view. The bolt 34 protrudes from the post 10 and can also be formed by a fastening means such as a screw, dowel pin or a spring-loaded pressure pin. The position of the wall 30 relative to the holder 32 can be changed from the underside of the holder 32 via the screw 36. The wall 30 also has protruding webs 38 for mounting a housing of the cassette 3.

In Figure 20 the cassette 3 is shown in a sectional view in the area of an electric drive 60 which is arranged inside the winding shaft 4. The electric drive 60 is supplied with power via the plug 61, which is in engagement with a connecting plug 62. The plug 61 can also ensure that the cassette 3 is mechanically fixed. The connecting plug 62 is held on a plate 63 which closes a hollow chamber of the post 10. As a result, lines (not shown) can be routed inside the hollow chamber in order to supply the connecting plug 62 and thus also the plug 61 with power.

In the Figures 21A and 21B the plug 61 and the connecting plug 62 are shown in detail. The plug 61 comprises plug-in elements which can be inserted into sockets of the connecting plug 62, wherein the plug 61 can of course also alternatively have sockets for projections on the connecting plug 62. The plug 61 is mounted on a plate 66 which has a connection 65 for electrical connection to the drive 60. The connecting plug 62 is mounted on a plate 63 which can cover a recess in the post 10 and on which a connection 64 for connection to an electrical line is provided on the rear side.

In the illustrated exemplary embodiments, the curtain 5 is in each case guided from the rolled-up position from top to bottom. It is of course also possible to install the cassette 3 on a lower bolt 2 and then to guide the curtain 5 upwards, the curtain 5 then not being tensioned by gravity and a drop bar 6, but by a tensioning mechanism with at least one spring. It is also possible to install the cassette 3 on a post 10 and to move the curtain 5 in the horizontal direction to an opposite post 10. An alignment of the curtain 5 inclined to the horizontal and vertical is also possible, for example in the case of a light roof.
