EP3783184B1 - Profile connector for connecting frame profiles and arrangement therewith - Google Patents

Description

The invention relates to a corner or center arrangement of a frame comprising a horizontally aligned and a vertically aligned frame profile with a profile connector for connecting the frame profiles in the corners and/or center areas of the frame for sliding doors, in particular sliding doors with lifting and lowering function.

A sliding door, in particular with a lifting and lowering function, comprises at least two leaves - a fixed leaf and a sliding leaf - which are arranged one behind the other in parallel planes and can be moved relative to one another. The leaves are in turn enclosed in a frame which is firmly connected to the masonry. It can be provided that the sliding leaf is raised relative to the fixed leaf and the frame when unlocking and lowered when locking.

Since sliding doors are very large frame structures, they cannot be prefabricated into finished frames using conventional corner welds. The transport and assembly of these oversized frame structures would not be practical. This is why the frame profiles are usually assembled at the installation site and connected to one another in the corner areas and/or middle areas.

The straight frame profiles are cut to their specified length and butt-jointed to form a frame using screw connections in all corners and, if necessary, a central area. The horizontal frame profiles have the maximum width, in whose clear dimension the vertical frame profiles, which form the left and right It is important that the end sections of the profiles in the corner area meet one another flush and without gaps.

According to the state of the art, thresholds are known which are provided with a gradient to the outside that drains water and thus have a sloping surface that slopes outwards in cross-section perpendicular to the longitudinal extension. In order to compensate for the slope to the straight cutting surface of the vertical frame profile that is oriented perpendicular to the longitudinal extension, it is known to insert wedge-shaped filler pieces between the horizontal threshold and the vertical frame profile standing on it, which close the gap.

Such a filler piece is shown, for example, in the Siegenia building connection manual in issue 04.2019 on page 13. At the same time, this filler piece also functions as a connector, since the long connecting screws are screwed from below the floor threshold through the connector into the vertical frame profile. This makes a stable and resilient corner connection possible.

A general disadvantage is that wherever the ends of frame profiles are joined together to form a butt joint, a flush connection must be created. It is also disadvantageous if different profiles, i.e. with different cross-sectional shapes, are used to form floor sills and the upper and side beams of a frame, as the gaps between the profiles must then be filled in a different way depending on the connection point.

Corner arrangements with profile connectors for connecting profiles with different profile surfaces are known, for example, from the publications FR 3 055 650 A1 and EP 2 818 624 A1 . GB2248648A discloses a corner or center arrangement of a frame according to the preamble of claim 1.

The applicant intends to use frame profiles for all the beams of a frame that have a stepped cross-section. Preferably, frame profiles that have an identical profile cross-section viewed perpendicular to the longitudinal extension should be used for all the beams of a frame.

The stepped course is present in the surface of the respective frame profile which faces the inside of the frame in the finished frame. In the corner connections and the middle areas, there is therefore a stepped surface of the horizontal and vertical frame profiles, which enclose a 90 degree angle between them.

This type of frame profile has the advantage that it can be used for each side of the frame, i.e. as side or middle vertical profiles as well as lower and upper horizontal profiles. Depending on the location of the arrangement, the stepped surface areas can be provided with insert profiles in order to achieve a desired functionality, e.g. in the case of a frame profile that is to form a floor threshold, an insert profile with a sloped run-off slope sloping towards the outside can be inserted into the stepped surface. The arrangement of the stepped frame profiles is preferably such that the step height in the profile cross-section decreases towards the outside. The invention described below should preferably be used in conjunction with such previously described frame profiles.

One embodiment of the frame profiles, to which the invention described below also preferably refers, provides that a frame profile has three profile sections lying one behind the other in its width direction, viewed from the intended inside to the outside, the surfaces of which decrease in level in stages (in particular compared to the underside). In particular, the surface area with the lowest step height is on the outside and the one with the highest step height is on the inside. The highest surface area can preferably include a groove for the rail guide of the sliding door. The surface areas of the profile sections arranged at different heights are preferably all parallel to one another, in particular, for a horizontal profile it is also horizontal and for a vertical profile it is also vertical.

The filler pieces mentioned at the beginning, which are only wedge-shaped in one direction, are not suitable for such profiles, since the same stepping in horizontal and vertical frame profiles results in a cross-sectional reduction in the connection area of the touching profile ends in two mutually perpendicular planes. A wedge shape cannot be used to fill a stepped shape in a force-fitting and form-fitting manner.

The object of the invention is therefore to fill the cavities in the connection areas of stepped frame profiles, at the vertically running profile ends in all four corners of the frame and preferably also at the center profile post at the profile ends with a suitable profile connector in order to achieve flush profile ends that can be firmly connected butt-jointly. This should preferably be achieved with as few profile connectors as possible with the same design features.

This object is achieved with a corner or center arrangement according to claim 1. The two partial lower surfaces have different distances from the said flat surface due to the stepped design of the lower surface formed from these partial lower surfaces. The same applies to the partial front surfaces in relation to the rear surface. Preferably, the flat surface and the flat rear surface are each to be understood as being completely flat in a single plane.

A connector of this type of construction has the advantage of being able to be used in any connection position between horizontal and vertical frame profiles which have a stepped surface, in particular with three steps, i.e. three sections with different height levels compared to the underside.

In this way, a corner or center arrangement of a frame according to the invention can be formed, which has a horizontally aligned and a vertically aligned frame profile with identically stepped frame profile surfaces facing towards the inside of the frame and a profile connector arranged between the frame profile surface of the horizontal frame profile and the cutting surface of the vertical frame profile lying perpendicular to the longitudinal direction.

According to the invention, the said lower surface of the profile connector can be placed on the stepped profile surface of a horizontal frame profile, preferably at least essentially in a form-fitting manner. This can preferably be achieved if the stepped lower surface of the profile connector is complementarily adapted to the stepped profile of the stepped frame profile surface of the horizontal frame profile.

The surface of the profile connector is also preferably arranged flush/level with the surface area of the horizontal frame profile, which has a rail guide groove. This can preferably be achieved if the height of the surface of the profile connector above its lowest partial lower surface corresponds to the height difference between the surfaces of the lowest and the highest level of the frame profile. According to the invention, the cutting surface of a vertical frame profile can therefore be butted flush with the surface of the profile connector. The cutting surface mentioned is designed at a 90 degree angle to the longitudinal direction of the profile and is parallel to the surface of the profile connector in the butt joint.

In particular, in a corner or central arrangement, the cutting surface of the vertical frame profile will partially butt-join the highest level surface area of the horizontal frame profile, in particular the area with the rail guide groove, and partially butt-join the surface of the profile connector.

According to the invention, the stepped front surface of the profile connector allows the stepped profile surface of a vertical frame profile to be extended in the longitudinal direction of the frame profile or to be extended in the installation situation. When installed correctly in the frame frame, the front surface of the profile connector therefore points towards the interior of the frame. In particular, each of the partial front surfaces of the profile connector is arranged in line with one of the stepped or different-level surfaces of the vertical frame profile, in particular as a result of this the course of the stepped surface of the vertical frame profile is continued in its longitudinal direction up to the stepped surface of the horizontal frame profile.

The rear surface of the profile connector can be positioned parallel to the cutting surface of a horizontal frame profile. In a corner in particular, this is flush with the cutting surface of the horizontal frame profile.

The profile connector can thus compensate for the hollow space at the profile end of the vertically running frame profiles, which is formed by the stair shape at the respective frame corner and at the middle section, in order to then be able to create a secure connection with the adjacent profiles.

The profile connector can also be understood as a body made up of essentially two body sections which represent a common, smooth surface in one plane, e.g. the xy plane of an assumed coordinate system, and which form a step on their underside. In particular, the two body sections can be understood as being offset from one another in two different planes. The profile connector is shaped in terms of its step shape, in particular the step height and step angle, so that it is complementary to the step shape of the e.g. horizontal frame profile and, after being attached to it, fills the stepped frame profile shape at the attachment point and thus at least essentially (apart from e.g. functional grooves and webs) supplements the frame profile to form a rectangular external cross-section, in particular while at the same time having the corresponding frame profile contour of the vertically attached profiles.

In an example application, the profile connectors are inserted from above onto the lower horizontal frame profile - which forms the threshold - on the outside in order to fill and compensate for the step offset of the frame profile so that a flush attachment surface is achieved. Insertion from below onto the upper horizontal frame profile is carried out in the same way.

The invention can provide the profile connectors in the design described here and in a mirror-image design, e.g. as a set. For example, a profile connector can be positioned at the left end and in a mirror-image design at the right end of the lower horizontal frame profile, in particular also in the middle, preferably also in the same way on the upper frame profile.

The invention can provide that the profile connector has on one side surface of the two opposite side surfaces in the transition area to the surface a material recess/material removal extending between the furthest protruding partial front surface and the rear surface, into which a locking projection of a horizontal frame profile can be inserted, in particular which continues the highest level surface of the stepped frame profile in the direction of the next lower surface, in particular thereby forming an undercut step.

The profile connector can be fixed to the locking bar of the frame profile using this material recess/removal. The connection is preferably designed in such a way that the profile connector holds its position even when inserted into the upper horizontal frame profile and cannot fall down due to gravity.

The profile connectors balance the stepped frame profile so that a continuous connection surface is formed. This connection surface is thus partly formed by the surface of the profile connector and partly by the highest level surface of the frame profile. Between the two at their profile ends and in the middle area on the side facing the inside of the frame Once the horizontally running frame profiles have been straightened on the side, the vertical left and right outer frame profiles and the center post profile can now be easily inserted into the clear dimension.

The profiles to be connected to each other are each firmly screwed together with long connecting screws from the top or bottom of the horizontal frame profiles, through the profile connector, into the attached vertical frame profiles.

In addition to its filling function, the compensation piece also fulfils the function of a connector.

The profile connector can preferably have, in the connection direction of its surface and its stepped lower surface, in particular in the region which comprises the downwardly projecting partial lower surface, a channel which runs completely through the profile connector, in particular for the passage of a connecting screw.

Due to the identical design of the frame profiles and the middle section, mirror-image, in particular otherwise identical profile connectors, in particular in left and right versions, can be used for the frame profile connection at the top, as well as at the bottom and at the end of the center post profile.

The profile connector is preferably a plastic injection-molded part with smooth visible surfaces so that it can be easily attached to the flat cutting surface of the vertically running frame profiles.

The profile connector preferably has a stepped shape in two mutually perpendicular planes. In one plane, the step shape is complementary to the step shape of the frame profile in height and angle β, so that this is filled by the profile connector, and in another plane, the profile connector has the same external step shape as the vertically running frame or center post profile according to the angle α. The profile connector thus extends the stepped contour of the vertically running profile cross-section to the surface of the horizontal frame profile.

The profile connector can be attached to the upper and lower ends of the two outer vertical frame profiles that form the frame. The compensation piece can also be attached to the end of the vertical center post profile, which is preferably formed by the same frame profile.

The frame profile forms the frame for both the fixed and sliding sash, which are arranged parallel to each other. The fixed sash is always attached to the outside of the building and the sliding sash is mounted on the room side and can be pushed behind the fixed sash.

The profile connector compensates for the outward-sloping, stepped frame profile in the area of the fixed sash level. For this reason, the profile connectors are preferably used exclusively in the outside frame profile area and are only visually visible with one of their side surfaces from the outside of the building.

The compensation piece is preferably an injection-molded part, in particular made of plastic. It is provided with material recesses that extend from the surface and the stepped lower surface, but in particular do not pass through the compensation piece to the opposite side. The first material recesses that open into the surface are preferably placed in three central areas, extend down towards the stepped lower surface, but do not break through the opposite lower surface. In the lower surface, second material recesses are preferably present in the edge areas. They extend up from the stepped lower surface towards the surface, thus open into the lower surface, but do not break through the surface.

The first and second material recesses are preferably arranged offset from one another.

The material recesses are preferably used to save material. They are preferably separated from each other by webs with the same wall thickness and/or the Side surfaces are separated so that even cooling of the injection-molded part and dimensional accuracy can be maintained.

The invention can provide that the downwardly projecting partial lower surface of the stepped lower surface carries a sealing plate, in particular one that can be placed on the lowest surface area of the stepped surface of a horizontal frame profile. This sealing plate is attached to the partial lower surface that faces the weather side of the frame and serves to seal the base of the rebate. The sealing plate can be molded directly onto the partial lower surface using an injection molding process or can be subsequently attached to it. The sealing plate is preferably made of an elastomeric material, e.g. rubber or silicone.

The invention can further provide that the recessed partial front surface forms an acute or obtuse angle (α) or an angle (α) of 90 degrees with the step side surface which connects the two partial front surfaces. Furthermore, the downwardly projecting partial lower surface can form an acute or obtuse angle (β) or an angle (β) of 90 degrees with the step side surface which connects the two partial lower surfaces.

It is further preferred if one side surface of the two opposite side surfaces has a groove running between the surface and the partial lower surface, in particular which is wider than the adjacent side surface areas. These side surface areas can then form spaced stop surfaces for contacting a parallel stepped side surface of a horizontal frame profile. The stepped side surface of the frame profile is understood to be a surface which connects two surfaces of the stepped frame profile in the direction of the distance between the surfaces/height direction.

Preferably, it is further provided that the profile connector in cross section is parallel to the surface in all planes between the surface and the closer partial lower surface (i.e. the partial surface of both partial lower surfaces with the smaller distance to the surface) and in cross section parallel to the rear surface in all planes between the rear surface and the closer partial front surface (i.e. the partial front surface of both partial front surfaces with the smaller distance to the rear surface) is each formed in an L-profile shape in the outer contour.

The invention is explained in more detail below with reference to the drawings.

The Figure 1 shows, with reference to a Cartesian coordinate system, a profile connector 10 of a corner or center arrangement according to the invention in a perspective view from above and from the front. The one-piece basic construction here essentially comprises two connected body sections 10a, 10b that are cuboid-shaped in their outer shape. In the Z direction, section 10a is shorter than section 10b. In the Y direction, section 10a is longer than section 10b. In the X direction, section 10a is longer than section 10b. However, this is not mandatory; the relationships can also be reversed or the sections can be the same length in the X direction.

It is important that the sections 10a, b and thus the entire profile connector 10 have a common, flat surface 13, here parallel to the xy plane of the selected coordinate system. On the underside of the profile connector 10, the sections 10a, b do not have a common flat lower surface, but rather respective partial lower surfaces 14, 15, in particular in different planes parallel to the X-Y plane. On the underside, the profile connector thus forms a stepped lower surface. The partial lower surfaces 14, 15 are connected by the stepped surface 16 running in the direction of their spacing.

On the rear side, the profile connector also forms a flat rear surface 16‴ common to both sections 10a, 10b. On the front side, sections 10a, 10b each have their own partial front surfaces 16" and 16', so that the overall has a stepped front surface.

Thus, in the profile connector of a corner or center arrangement according to the invention, both the front surface and the bottom surface are stepped, and the top and back surfaces are each flat.

The terms surface, bottom surface, front surface and back surface are chosen with reference to an installation situation of the Figure 1 shown profile connector in a lower corner of a frame when the corner is viewed from the inside of the frame. Accordingly, in this view, the surface 13 is at the top, the stepped lower surface 14,15 at the bottom, the stepped front surface 16', 16" at the front and the rear surface 16‴ at the back. The side surfaces 11 and 12 are positioned so that the side surface 11 is on the outside, i.e. on the weather side of the frame, and the side surface 12 is on the inside, i.e. on the room side. In other arrangements and viewing directions, the directional relationships are to be understood as being adjusted accordingly.

According to the invention, the profile connector 10 with the stepped lower surface 14, 15 can be inserted from above into the complementary stepped contour of the surface of a horizontal frame profile 20 and fill it, whereby the stepped front surface 16', 16" is then aligned with the stair step course in the longitudinal direction of a vertical frame profile 20 placed on the surface 13, thus extending its step contour. The surface of a stepped frame profile 20 is understood to be the surface that faces the interior of the frame. In the case of a horizontal lower frame profile 20, the stepped surface of the frame profile 20 is also simultaneously the stepped surface located above.

Viewed from above, the profile connector 10 is angular, in particular in the form of an L-profile with two legs at 90 degrees. The angle α enclosed between the sections 10a, 10b, more precisely between the partial front surface 16 and the step side surface 16, is acute or obtuse or preferably right-angled, and spanned in a plane parallel to the xy plane. The angle is always complementary to the frame profile contour at the corresponding point. The embodiment shown is preferably designed to be right-angled. The angle α arises between the step side surface 16, which is the partial front surface 16" of the section 10a and the partial front surface 16' of section 10b. The step side surface 16 and the partial front surface 'of section 10b form the extension of the vertical frame profiles and the angle α corresponds to the step shape of the frame profile 20 and does not necessarily have to be right-angled.

The surface 13 of the profile connector 10 has material recesses 17', 17", and 17‴, which serve to save material. The recesses 17' and 17" surround a web wall 17a. The material recesses do not penetrate the respective lower surfaces of the sections 10a, b or the stepped lower surface 14, 15 of the profile connector 10.

The remaining material base on the underside preferably has the same thickness as the web walls 17a. This is intended to ensure that the plastic injection-molded part cools as evenly as possible in order to maintain dimensional accuracy. When installed, only the side visible surface 11 of the profile connector 10 is visible from the outside of the building. The inner side surface 12 is covered by a step surface of the stepped surface of the frame profile 20, which connects two surface areas at different levels.

Between the recess 17" and the recess 17‴ there is a cylindrical through-channel 19 through which the connecting screws 22 according to Figure 6b be pushed through.

On the underside, on the partial lower surface 15 of section 10b, there is a sealing plate 15a. This is attached to the partial lower surface 15, e.g. cast or glued.

The Figure 2 shows the profile connector 10 in perspective view from below and from the front. The two sections 10a, 10b that form the one-piece compensation piece 10 are shown.

The recesses 18, which are visible from the bottom, are offset from the recesses 17', 17", 17‴ on the top. In built-in In this state, the preferably elastic sealing plate 15a serves to seal the rebate base of the frame profile 20. The section 10a is set back from the adjacent section 10b by one step with the step surface 16 and with the step surface 14' (seen in Figure 3 ), but have a common surface in the respective offset direction that runs flat over both sections, namely the rear surface 16‴ and the surface 13.

In Figure 3 the profile connector 10 is shown in a perspective view from above and from the back. The side surface 12 has a groove running between the surface 13 and the partial lower surface 15, whereby the side surface forms two side surface areas that form stop surfaces so that the profile connector 10 lies flat on a step side surface of the frame profile, which connects two surfaces at different levels in the direction of their spacing. The side surface 12 thus forms two stop surfaces that position the profile connector 10 on the frame profile 20 so that it cannot tip over.

When the profile connector 10 is inserted into the frame profile 20, it snaps into the locking bar 21 of the frame profile 20 due to the incorporated material recess 12a, so that the profile connector is securely fixed. This locking bar extends the highest surface of the stepped frame profile in the direction of the next lowest surface. The locking bar 21 is particularly important when mounting on the upper frame profile, because the locking prevents the profile connector 10 from falling down.

The two angles α and β are in the Figure 3 recognizable. Angle α is formed between the step surface 16 and the partial front surface 16' in the xy plane and serves to extend the profile contour of the vertically running profiles. The angle β spans between the partial lower surface 14 and the step side surface 14' in the zx plane and forms a step with the height H1, which results from the distance of the partial lower surface 14 to the sealing plate 15a and fills the steps of the horizontal frame profile 20.

The Figure 4 shows the profile connector 10 in perspective view, in the area of the lower middle section, according to section AA of Figure 5 . The frame profile 20 acts as a threshold, which is designed to descend in a step-like manner towards the outside of the building. On the outside, the bottom right corner of the installed fixed sash 1 can be seen in the cutout and in the background, on the second level, a cutout of the installed sliding sash 2 is shown.

In order to be able to place the smoothly cut center post profile 50, the stepped surface contour of the frame profile 20 needs to be leveled to create a straight surface. The profile connector 10 fills the angular cavity, which is shown in the sectional view in Figure 4a shows. The profile connector 10 used, due to its complementary geometry, exactly fills the step offset of the frame profile 20 at the two lower steps and thus creates a flat attachment surface c.

The Figure 5 shows a lift-sliding door/sliding door 100 in the closed state viewed from the outside, with built-in profile connectors 10 and visible side surface 11. The profile connector 10 is used on both sides of the external frame profiles 20 and on the center post profile 50, i.e. in six positions. The profile connector is used in the design shown in the figures and in a mirror image. The fixed leaf 1 is arranged on the outside of the building and the sliding leaf 1 can be seen in the plane parallel behind it. To open the lift-sliding door/sliding door 100, the sliding leaf 2 is moved behind the fixed leaf 1. Both leaves are enclosed/surrounded and held by the frame 20.

Both the fixed and the sliding sash can be mitred at the corners below 45 degrees and welded at the corners without any joints.

The frame profiles 20 are connected butt-to-butt to form the frame and are firmly screwed together. The profiles to be joined must lie flat and flush against each other in the connection area. To achieve this, the profile connectors 10 are used at three positions on the lower and upper frame profile 20. This is the case wherever Figure 4a the stepped frame profile 20 must be filled up to form a vertically inserted profile.

The Figure 6 shows a lift-sliding door/sliding door 100 in perspective view from the outside, with visible profile connectors in the corner areas 6a and 6b. The fixed leaf 1 in the front level, the sliding leaf 2 in the level behind it and the right corner areas 6a, 6b of the lift-sliding door/sliding door 100 are clearly visible.

The Figure 6a shows a detail enlargement according to the Figure 6 with the profile connector 10 on the upper horizontal frame profile 20 in installed state and Figure 6b shows a detail enlargement according to the Figure 6 with profile connector 10 on the lower horizontal frame profile in installed condition. In the Figure 6a the stepped bottom surface points upwards, in the Figure 6b downwards. The profile connectors 10 of the Figures 6a and 6b are mirror images of each other, but otherwise structurally identical.

Figure 6b represents the spatial representation of Figure 4a The filling function of the profile connector for the frame profile 20 is shown, with the aim of generating the flat attachment surface c onto which the vertically running frame profile 20 can be placed. The attachment surface c is formed by the surface 13 of the profile connector 10 and the flush highest surface of the frame profile 20. The connecting screws 22 are inserted from the bottom or, accordingly, from the top of the horizontally running frame profiles 20. The profile connector 10 functions as a connector in that by filling the cavity caused by the stairs between the frame profiles 20 that meet in the corners, a stable corner solution can be achieved using the connecting screws 22.

Arrangement according to one of the preceding claims, characterized in that the downwardly protruding partial lower face (15) of the stepped lower face (14, 15) bears a sealing plate (15a), in particular which is placed on that surface region of the stepped surface of a horizontal frame profile (20) that is at the lowest height.
6. Arrangement according to one of the preceding claims, characterized in that the recessed partial front face (16') forms an acute or obtuse angle (α) or an angle (α) of 90 degrees with the step side face (16) that connects the two partial front faces (16', 16").
7. Arrangement according to one of the preceding claims, characterized in that the downwardly protruding partial lower face (15) forms an acute or obtuse angle (β) or an angle (β) of 90 degrees with the step side face (14') that connects the two partial lower faces (14, 15).
8. Arrangement according to one of the preceding claims, characterized in that a channel is made completely through the profile connector, preferably for the passage of a connecting screw, in the connection direction of the surface (13) and the stepped lower face (14, 15), in particular in the region which comprises the downwardly protruding partial lower face (15).
9. Arrangement according to one of the preceding claims, characterized in that material recesses (17', 17", 17‴), which lead into the surface (13) and do not interrupt the lower face (14, 15), extend down from the surface (13) towards the stepped lower face (14, 15).
10. Arrangement according to one of the preceding claims, characterized in that second material recesses (18), which lead into the lower face (14, 15) and do not interrupt the surface (13), extend up from the stepped lower face (14, 15) towards the surface (13).
11. Arrangement according to either of the preceding Claims 9 and 10, characterized in that the first and second material recesses are offset in relation to one another.
12. Arrangement according to one of the preceding claims, characterized in that one side face (12) of the two mutually opposite side faces (11, 12) has a groove which extends between the surface (13) and the partial lower face (15) and in particular is wider than the adjoining side face regions, which form spaced-apart stop faces for contacting a parallel step side face of a horizontal frame profile (20).
13. Arrangement according to one of the preceding claims, characterized in that one side face (12) of the two mutually opposite side faces (11, 12), in particular which has a groove according to Claim 12, has, at the transition region to the surface (13), a material recess/absence of material which extends between the furthest protruding partial front face (16") and the back face (16‴) and into which a latching projection (21) of a horizontal frame profile (20) can be inserted, in particular which continues the highest-up surface of the stepped frame profile (20) towards the surface that is next lowest down, in particular in this way forming an undercut step.
14. Arrangement according to Claim 13, characterized in that a latching projection, which is formed on the surface region of the rail guide of the horizontal frame profile (20) and which forms an undercut step on the horizontal frame profile (20), is made in the material recess.
15. Arrangement according to one of the preceding claims, characterized in that its outer contour respectively has an L profile-shaped form in cross section parallel to the surface (13) in all planes between the surface (13) and the closer partial lower face (14) and in cross section parallel to the back face (16‴) in all planes between the back face (16‴) and the closer partial front face (16') .
