Description

The present invention relates to a door leaf of a sliding gate, wherein a lower part of the door leaf is formed by a lower spar and an upper part of the Torblatts by an upper spar and wherein between the lower spar and the upper spar a Torblattfüllung is arranged. Moreover, the invention relates to a modular system for producing such a door leaf.

Door leaves of the type indicated above are well known from their widespread practical use. Usually, the lower beam and the upper beam each consist of a one-piece profile, which, for example, seen in cross-section C- or U-shaped. The profiles are also usually Abkantprofile steel or extruded aluminum. Depending on the length and height of the door leaf and depending on its weight, the profiles that make up the lower beam and the upper beam must be suitably dimensioned in order to safely and permanently absorb the static and dynamic loads occurring during operation of an associated sliding gate. Because door leaves can have very different sizes, a manufacturer of sliding gates or door leaves must accordingly manufacture or buy many different profiles, which requires a high manufacturing and logistical effort.

For the present invention, therefore, the task is to create a door leaf of the type specified above, which can be produced as required in terms of male loads and thereby requires a reduced effort manufacturing technology.

The solution of the door leaf part of the task succeeds according to the invention with a door leaf of the type mentioned, which is characterized in that the lower beam in a modular design of at least one pair consists of two in a plane parallel to Torblattebene plane interconnected profiles.

With the invention is advantageously achieved that a door leaf, here at least be the essential supporting function ausübender sub-spar, can be made in a modular design. In the minimum case, the lower beam consists of two interconnected profiles. The connecting plane of the interconnected profiles lies in a plane parallel to the door leaf level, wherein a position is included in the Torblattebene. Depending on the size of the door leaf, differently dimensioned profiles may be used. Furthermore, it is possible to manufacture the lower beam of more than one pair of profiles in order to obtain a particularly stable lower beam. A further advantage of the invention is that the manufacture and joining of two smaller profiles is simpler and less expensive than the production of a one-piece or one-piece large profile corresponding in size to the two smaller interconnected profiles. The number of required in practice for the door leaf according to the invention differently dimensioned profiles can thus be kept low, which simplifies the production of the door leaf and makes it cheaper.

Furthermore, the invention proposes that the upper spar consists of modular construction of at least a pair of two in a plane parallel to the Torblattebene plane interconnected profiles. With this development of the invention, the above-mentioned advantages are also transferred to the upper spar of the door leaf, which results in a further simplification of the manufacture of the Torblatts in different sizes.

According to the present invention, there is also the possibility that end and / or intermediate bars connecting the lower beam and the upper beam in a modular construction each consist of at least one pair of two profiles interconnected in a plane parallel to the door leaf plane. In this embodiment of the invention, the end and / or intermediate rods are included in the cheap modular design.

Preferably, it is further provided that in each case the profiles of a pair are identical to each other and are arranged mirror-symmetrically to each other. Hereby becomes Achieves a particularly high efficiency, since only a few different profiles are needed.

If necessary, however, it is also possible that each of the profiles of a pair are different from each other, for example, if for functional reasons, a non-symmetrical design of the lower spar or the upper spar or the end and / or intermediate rods is necessary. It remains unchanged, however, that in each case the profiles of a pair are connected to each other in a plane parallel to the door leaf level or in the Torblattebene.

Further, the invention provides that in each case the profiles of a pair are connected to each other by at least one continuous connecting profile or by a plurality of adjoining or spaced apart in the profile longitudinal direction of the connecting profile sections. Such connection profiles or connecting profile sections allow a simple and secure connection of the profiles of a pair with each other, without the need for elaborate machining operations or welds on the profiles.

As mentioned above, a spar, in particular the most heavily loaded lower beam, of the door leaf may be modularly composed of two or more profile pairs. For these embodiments, the invention provides that the profiles of adjacent pairs are connected to one another by an arrangement of at least two parallel, continuous connection profiles or by a plurality of adjoining or spaced arrangements in the profile longitudinal direction of at least two parallel connection profile sections, wherein the parallel connection profiles or connection profile sections are clamped or braced against each other transversely to the profile longitudinal direction.

To ensure a consistently accurate over the entire length of a door leaf alignment of superposed profile pairs relative to each other is proposed that seen in cross section between the at least two parallel, continuous connection profiles or the at least two parallel connection profile sections at least one continuous or in adjoining or spaced sections divided centering profile is arranged.

An essential contribution to the reduction of the parts required and thus to the simplification of the manufacture of the door leaf is achieved in that preferably the connecting profile or the connecting profile sections are identical for all profiles to be joined together.

According to the invention, it is further preferred for the profiles to have positive or negative undercut edge regions in cross-section at their lateral or longitudinal edges facing each other, and that the connection profile or the connection profile sections have / have complementary, negative or positive undercut edge regions , With this design, a favorable positive connection between two profiles or profile sections on the one hand and a connection profile or connection profile section on the other hand possible.

In a related development, the edge regions in cross-section are preferably positive or negative hook-shaped or hammerhead-shaped. By centering bevels on the edge areas of the assembly can be simplified.

With the above-mentioned design of the profiles and connection profiles with positively cooperating, undercut edge regions is advantageously created the possibility that in each case two profiles to be joined together and the connecting profile connecting them or these connecting profile sections can be brought by axial telescoping in connection. This provides a particularly simple and at the same time very effective connection technology for the profiles and connection profiles.

In an alternative development, there is the possibility that in each case two profiles to be connected to each other and two connecting these parallel connecting profiles or Verbindungsprofilabschnitte by transversely to the axial direction joining together and attaching each of the two parallel connection profiles or Verbindungsprofilabschnitte against each other bracing clamping means are brought into connection. If subsequent damage-free dismantling of the door leaf is not desired, gluing can also be used instead of the clamping device.

A further development preferably provides that the clamping means are formed by clamping screws or rivets and that the connecting profiles or connecting profile sections are provided with prefabricated apertures for the clamping means and / or for filling rods to be attached.

A particularly favorable ratio of weight to bearing capacity of the profiles of the door leaf can be achieved in that the profiles are extruded profiles, preferably hollow-chamber extruded sections, made of light metal, preferably aluminum.

Since the cost of profiles increase disproportionately with their length when exceeding a certain length, it is further proposed that at least part of the profiles of blunt abutting profile sections and that within a pair of interconnected profiles, the joints of one profile against the joints of the other Profiles are offset in the axial direction. Thus, it is possible to arrange a plurality of profile sections behind one another within a sub-spar or upper spar of the door leaf, as seen in its longitudinal direction, in order to form a spar of a desired, longer length from a plurality of shorter profile sections. Due to the axial offset of the joint in step by this use of several profile sections no significant weakening of the spar on and the profile material can be used almost completely.

To increase the resilience and safety of Holmes executed in the above-mentioned type may additionally be provided that two butt abutting profile sections connected by at least one positive and / or non-positively engaging in one of the hollow chambers of each profile section bridging element on the butt joint away or connectable are.

To avoid penetration of possibly leading to corrosion moisture in fissures in the region of a longitudinal joint between interconnected pairs of profiles, it is proposed that the door leaf at least one, preferably latchable or clampable or anklebbares, cover profile, preferably made of plastic, having a longitudinal joint two interconnected pairs of profiles is concealable. In addition, such a cover profile contribute to the improvement of the visual appearance, for example in such a way that two interconnected pairs of profiles outwardly offer the appearance of a one-piece profile.

It is further provided according to the invention that at least one of the profiles in cross-section is C-shaped and that in the connected state of two of these profiles by means of a mounted on the upper longitudinal edge connection profile or pair of two parallel connection profiles, the profiles a rectangular in cross-section, below a continuous slot and inside two upper and two lower roller tracks having Holm form. In this embodiment, support rollers and / or drive rollers as well as a correspondingly "slim" shaped drive unit with motor and gear can be arranged inside the spar or the spars.

The present invention also provides an embodiment in which at least one of the profiles is flat rectangular in cross-section, wherein in the connected state of two of these profiles by means of two attached at the upper and lower longitudinal edges parallel connecting profiles form the profiles a cross-sectionally closed spar or rod. Such a closed spar is preferably used as an upper spar. Such a spar can also be used as a lower spar if the carrying rollers and / or drive rollers and a drive unit of the sliding gate are arranged outside the lower beam.

To achieve a high stability of the spars or bars and to avoid sharp edges on the bars or bars of the door leaf, it is proposed that the spar or bar has seen in cross-section bevelled or rounded outer and / or inner corner regions.

As is generally known from gate leaves of sliding gates, their Torblattfüllung can be designed very different. In particular, either vertical bars or flat fillings, for example plates made of sheet metal or plastic, are customary. For the latter embodiment, it is proposed that the connecting profile or the connecting profile sections at its in the installed state facing the interior of the door leaf side at least one extending in the profile longitudinal attachment means, such as flange or groove or spring, for a flat Torblattfüllung has / have. At this attachment means can then the area Torblattfüllung be very easily attached, for example by screws or rivets or welds or simply by positive insertion.

In a concrete, particularly preferred embodiment of the invention, it is provided for the door leaf that it can be produced in a modular system of only three differently sized cross-section profiles and a uniform connection profile, wherein the largest profile for forming the lower spar and / or Oberholms is usable wherein the central profile for reinforcing the sub-spar and / or for forming the upper spar and / or for forming the end and / or intermediate rods is usable and wherein the smallest profile for reinforcing the sub-spar and / or to form the upper spar and / or Forming the end and / or intermediate rods is usable. In this embodiment, advantageously only three differently executed profiles and a uniform connection profile are needed, so a total of only four different profiles. With this very small number of different profiles door leaves can be made over the entire size range required in practice, each with matching static and dynamic load capacity by each of the necessary and suitable profiles are combined.

Finally, the invention proposes a modular system for producing a door leaf of the type described above. The module system according to the invention is characterized in that it consists of only three profiles of different dimensions and a uniform connection profile, the largest profile serving to form the lower spar and / or the upper spar of a door leaf, the middle profile reinforcing the lower spar and / or or to form the upper spar and / or to form the end and / or intermediate bars of a door leaf, and wherein the smallest profile for reinforcing the lower spar and / or for forming the upper spar and / or for forming the end and / or intermediate bars of a Torblatts serves. With this module system, differently dimensioned door leaves for sliding gates can be produced from a few parts and thereby cost-effectively.

FIG. 1 shows a section of a door leaf 1 in a perspective view in a first embodiment, which is particularly suitable for smaller door leaves. A lower beam 11 forms the main supporting part of the door leaf 1 and consists of two cross-sectionally C-shaped profiles whose open sides face each other and which are interconnected along their parallel upper edges.

Another supporting part of the door leaf 1 forms its upper beam 12, which is also formed of two in cross-section C-shaped, compared to the lower beam 11 smaller profiles, which are also facing each other with their open sides and along both their parallel upper edges are also interconnected along their parallel lower edges.

At the two ends of the door leaf 1 or if necessary between them are arranged end or intermediate rods 13 vertically, forming a stable connection between the lower beam 11 and upper beam 12. The in FIG. 1 visible intermediate rod 13 is identical to the upper spar 12 executed. Parallel to the intermediate rods 13 extend a plurality of filler rods 14, which have no supporting function, but form a filling of the door leaf 1.

FIG. 2 shows the structure of the door leaf 1 and its parts in detail with reference to an end view of the door leaf 1. Below the lower beam 11 is visible from which extends the end or intermediate rod 13 upwards. Above is the upper beam 12, which closes the door leaf 1 upwards.

The lower beam 11 is composed of two mutually mirror-symmetrically arranged profiles 2.1, which are interconnected along their upper parallel edges by means of two connecting profiles 3. The two profiles 2.1 are identical to each other and made here as extruded profiles of, for example, aluminum. To achieve a high load capacity with low weight, the profiles 2.1 are double-walled with hollow chambers 25. In addition, each profile has 2.1 in its upper corner areas and its lower corner each have a circular cross-section channel 25 '. These channels 25 'are used to connect butt sections of the profiles 2.1, which is based on the FIG. 12 will be explained in more detail below.

The profiles 2.1 are C-shaped in cross-section and face each other with their open sides. Since the profiles 2.1 are connected to each other only at their upper parallel edges, remains at the bottom of the sub-spar 11 is a continuous Slot 11.1. This slot 11.1 serves for the passage of support elements, the rollers and drive rollers and possibly also receive a drive unit of the associated sliding gate. Inside the lower beam 11, the two profiles 2.1 form two parallel upper and two parallel lower roller tracks 11.2. The inner corner regions 29 of the profiles 2.1 are rounded or chamfered to guide the rollers and the lower beam 11 relative to each other well. The outer corner regions 28 of the profiles 2.1 are chamfered to avoid sharp corners

To connect the two sub-beam 11 forming profiles 2.1 serve two mutually parallel connection profiles 3. Each connection profile 3 has at its longitudinal edges two hook-shaped edge portions 30 which engage positively behind correspondingly shaped edge portions 20 of the profiles 2.1. By means of two pairs of side by side and longitudinally mounted in a grid spacing clamping means 4, here screws, the two connecting profiles 3 against each other firmly but releasably braced so that they connect the two profiles 2.1 to the lower beam 11 together.

The in FIG. 2 visible end or intermediate rod 13 is also by means of another connecting means 4, such as a screw, with the upper of the two connecting sections 3 of the sub-spar 11, but releasably connected. In the same way as the end or intermediate rod 13 are also in FIG. 1 visible filler rods 14 connected to the lower beam 11 and its upper connecting section 3.

The upper beam 12 consists here of two parallel profiles 2.3 which are significantly smaller than the profiles 2.1 in their dimensions. The profiles 2.3 can also be used for the end or intermediate rods 13; Alternatively, the profiles for the end or intermediate rods 13 may also be slightly smaller than the profiles 2.3. The profiles 2.3 are identical to each other and also as hollow extruded profiles, for example made of aluminum. The profiles 2.3 are connected to each other via connecting profiles 3, wherein in each case a connecting profile 3 is attached to the top and at the bottom of the upper spar 12 here. The two connection profiles 3 are against each other by the clamping means 4, also here a screw, fixed, but releasably braced. For mutual positive engagement also here have the connection profiles 3, which are identical to the connection profiles 3 of the sub-spar 11, the hook-shaped edge regions 30 at their longitudinal edges, which engage positively behind correspondingly shaped edge regions 20 of the two profiles 2.3. Furthermore, runs through each profile 2.3 a round in cross-section channel 25 ', which serves for butt-splitting connection of profiles 2.3.

By means of two further clamping means 4, here also screws, which are guided only by the lower connecting section 3 of the upper spar 12 down, the upper beam 12 with the end or intermediate rod 13 is fixed, but releasably connected.

Thus, all parts of the door leaf 1 by releasable connection means, namely the connection profiles 3 and the clamping means 4, connected to each other. Therefore, the door leaf 1 can be disassembled harmless into its parts to replace, if necessary, individual parts in case of damage. In addition, the manufacture of the door leaf requires no complex welding, which simplifies the production and avoids undesirable and straightening required warping the door panel 1 by the heat generated during welding.

FIG. 3 shows an example of the door leaf 1, in which compared to the example of the FIGS. 1 and 2 the lower beam 11 is made reinforced. For this purpose, the lower beam 11 consists of two pairs of interconnected profiles, the lower profile pair of the lower beam 11 according to FIG. 1 corresponds to which now another profile pair, which is identical to the upper beam 12, is placed. Thus, the carrying capacity of the sub-spar 11 is compared to the example FIG. 1 and 2 elevated. The end or intermediate rod 13 and the filler rods 14 correspond in the example according to FIG. 3 the first embodiment.

FIG. 4 shows in detail in front view of the structure of the door leaf 1 according to FIG. 3 , Below the lower beam 11 is shown, which is composed of two profile pairs. The lower profile pair consists of two profiles 2.1, as they are already in FIG. 2 have been described. On the top of the profile pair from the profiles 2.1 an arrangement of two profiles 2.3 is arranged as a further pair of profiles, the upper beam 12 according to FIG. 1 and 2 correspond.

To connect the profiles 2.1 and 2.3 of each pair serve again here two connection profiles 3, which are connected to the connection profiles 3 according to FIG. 2 are identical. In addition, a centering profile 3 'is arranged here between the profile pairs. The connecting profiles 3 and also the centering profile 3 'here have the hook-shaped edge regions 30, which form-fit behind accordingly oppositely shaped edge regions 20 of the profiles 2.1 and 2.3. The lower connection profile 3 is fixedly connected to the centering profile 3 'via fasteners 4, here screws, which are attached side by side and in the longitudinal direction at a grid spacing. Furthermore, the centering 3 'by another clamping means 4, here a longer screw, with the upper connecting section 3 again firmly, but releasably connected. In this way, both the profiles 2.1 and 2.3 within each profile pair and the two profile pairs are connected to each other to the lower beam 11. On its underside, the lower beam 11 again has the longitudinal slot 11.1.

With the top of the sub-spar 11 here is the end or intermediate rod 13 by means of two by the upper connecting section 3 of the sub-spar 11 upwardly guided clamping means 4, also screws here, connected. The upper beam 12 here corresponds to the upper beam 12 according to FIG. 2 and is the same as in FIG. 2 connected to the end or intermediate rod 13. Regarding the further in FIG. 4 The reference numbers appearing on the description of the FIG. 2 directed.

In FIG. 5 a third example of a door leaf 1 is shown, for which it is characteristic that the lower beam 11 is reinforced here again. For this purpose is also here, as in FIG. 3 , the sub-spar 11 composed of two profile pairs. Unlike the example below FIG. 3 is in FIG. 5 the upper profile pair of the sub-spar 11 but larger dimensions, so that there is a further increase the carrying capacity of the sub-spar 11. In its other parts corresponds to the door leaf 1 of Figure five by example FIG. 3 ,

FIG. 6 shows the structure of the door leaf 1 after FIG. 5 in detail on the basis of a front view. The lower beam 11 consists, as mentioned, of two superposed profile pairs of two profiles 2.1 and two profiles 2.2. The profiles 2.1 of the lower profile pair of the sub-spar 11 are in accordance with the profiles 2.1 of the lower profile pair of the sub-spar 11 FIG. 4 identical. The upper profile pair of the sub-spar 11 according to FIG. 6 consists here of the two profiles 2.2, which have the same width as profile pair in interconnected state as the profile pair of the profiles 2.1, but these have a lower height.

The in FIG. 6 visible end bar 13 is again, as well as the upper beam 12, each of two profiles 2.3.

The sub-beam 11 forming profiles 2.1 and 2.2 are connected to each other by means of the connecting profiles 3 and the centering 3 'in the same manner as the profiles 2.1 and 2.3 of the sub-spar 11 according to FIG. 4 , so that reference is made in this regard to the preceding description. The same applies to the connection of the end bar 13 and the upper beam 12 forming profiles 2.3, both in terms of connection with each other and with respect to the connection to the lower beam 11, so that reference is made in this regard to the preceding description.

In their dimensions are the profiles 2.2 between the stronger sections 2.1 and the weaker sections 2. 3, so that the lower beam 11 according to FIG. 6 one over the embodiment according to the Figures 1 - 4 again increased carrying capacity. Also in the example FIG. 5 and 6 are all parts of the door leaf 1 with each other by the clamping means 4 sufficiently strong, but non-destructively releasably connected.

FIG. 7 shows another example of a door leaf 1, the lower beam 11 and end or intermediate rod 13 the example according to the Figures 5 and 6 correspond. This is different in the example FIG. 7 the upper beam 12 is formed, namely with a larger profile dimensioning in order to achieve a further increase in the load capacity of the door leaf 1.

FIG. 8 shows the door leaf 1 FIG. 7 in detail again in front view. The lower beam 11 and the end bar 13 according to FIG. 8 identical to the version according to FIG. 6 , whose description is referenced.

The upper spar 12, coinciding with the upper part of the lower spar 11, in the example FIG. 8 formed from two mirror-symmetrically arranged profiles 2.2. In the upper beam 12, the two profiles are 2.2 by means of two parallel connecting profiles 3 and this against each other bracing clamping means 4, here again screws, sufficiently strong, but releasably connected to each other. The connection profiles 3 in the upper beam 12 are identical to the connection profiles 3 used in the lower beam 11 again. By means of two rows of others Clamping means 4, again screws, the upper beam 12 is connected through its lower connection profile 3 passes through to the upper end of the end bar 13. By means of further, not visible here clamping means of the upper beam 12 is also with the in FIG. 8 concealed, not visible Füllstäben connected.

By using the profiles 2.2 for the upper beam 12 of this receives in comparison to the versions of the Figures 1-6 a stronger version, which results in a higher stability and load capacity of the entire door leaf 1.

FIG. 9 shows a reinforced embodiment of a door leaf 1. Characteristic of this embodiment of the door leaf 1 is that the lower beam 11 is formed of two identical, superimposed pairs of profiles. The upper beam 12, the end or intermediate rod 13 and the filler rods 14 according to the embodiment of the FIGS. 7 and 8th , whose description is referenced.

In FIG. 10 is the door leaf 1 off FIG. 9 again shown in a detailed front view. The lower beam 11 here consists of two identical pairs of profiles 2.1, which are arranged one above the other and connected to each other. To connect the profiles 2.1 of the sub-spar 11 again serve the already described connection profiles 3 and the centering 3 'and this against each other bracing clamping means 4 in the form of screws.

The lower profile pair and the upper profile pair of the lower spar 11 form a horizontally extending longitudinal joint 26, which is due to the bevelled outer corner regions 28 of the profiles 2.1 in each case an outwardly open wedge-shaped recess. In the example below FIG. 10 the outer corner regions 28 are provided with longitudinal locking grooves 26 'in order to be able to attach a cover profile there if required, as shown in FIG FIG. 11 will be described.

The upper beam 12 and the end or intermediate rod 13 in the example according to FIG. 10 the already described embodiment FIG. 8 , whose description is referenced.

In the examples described above, the two profiles 2.1, 2.2, 2.3 of a pair are identical to each other. If necessary, especially for technical reasons, the profiles of a pair may differ from each other be, but always their connectivity in a connecting plane that runs parallel to the Torblattebene or in Torblattebene remains. For example, in otherwise existing agreement, one of the two profiles of a pair may have a groove for receiving a rack, while the other of the two profiles of the pair may not have such a groove.

The FIG. 11 shows in an enlarged section of an end view of a lower beam 11, the attachment of the aforementioned cover profile 6. Bottom of FIG. 11 is a profile 2.1 and above a profile 2.2 of the sub-spar 11 visible, both having beveled outer corner regions 28. In the longitudinal joint 26, the profiles abut each other. Left in FIG. 11 is still a part of a connection profile 3 and a centering profile 3 'visible; the respectively symmetrically arranged second profile 2.1 and 2.2 of each profile pair of the sub-spar 11 is in FIG. 11 not visible anymore.

In each of the adjacent outer corner regions 28 of the two interconnected profiles 2.1 and 2.2, a latching groove 26 'is provided, in which a cover profile 6 formed as a plastic profile is latched by means of two latching tongues 60 with latching hooks engaging in the latching grooves 26'. In this way, the wedge-shaped recess in the region of the longitudinal joint 26 is optically hidden, so that the external impression arises that the profiles 2.1 and 2.2 are integral with one another. In addition, the cover profile 6 protects the lower beam 11 against harmful penetration and deposition of dirt and moisture in the region of the longitudinal joint 26th

In the described examples of the door leaf 1 according to the invention, the profiles used are 2.1 - 2.3 extruded aluminum profiles. In order to be able to use such profiles, which are relatively expensive to manufacture, as waste-free as possible, according to FIG. 12 the possibility of assembling, in particular, the lower beam 11 or the upper beam 12 from butt section sections 2.1 'and 2.1 "For this purpose, the channels 25' provided in the various profiles described above serve, in each case in the region of an obtuse joint 27, a bridging element 5 can be used in the example FIG. 12 the bridging element 5 consists of two threaded sleeves 51 and 52. The first threaded sleeve 51 is screwed with a self-tapping external thread from the free end of a profile section 2.1 'in the channel 25' and has a bore with a threadless inner circumference. The second threaded sleeve 52 is also screwed into the channel 25 'with a self-tapping thread from the free end of the other profile section 2.1 and has a bore with an internal thread Profile section 2.1 "survives.

In the interconnected state of the profile sections 2.1 'and 2.1 ", the centering 52' protrudes into the channel 25 'of the first profile section 2.1', whereby the profile sections 2.1 'and 2.1" are aligned with each other exactly. By means of a screw 53, which is inserted through the first threaded sleeve 51 with the interposition of a washer 54 and screwed into the internal thread of the second threaded sleeve 52, the profile sections 2.1 'and 2.1 "are mechanically fixed, but non-destructively releasably connected to one another the screw 53 is a sufficiently long screwing, which is introduced from the joint 27 remote from the other free end of the first profile section 2.1 'in the channel 25'.

Depending on the load to be expected, the profile sections 2.1 'and 2.1 "to be connected to one another may each have one or more channels 25. Within a profile pair, blunt joints 27 in the two profiles are expediently arranged offset sufficiently far in the longitudinal direction of the profile.

In FIG. 13 a special embodiment of the connection profile 3 is shown, which here an attachment means 35 for a flat door leaf filling 15, which can be used instead of parallel filler bars 14 has. As already described above, the connecting profile 3 has hook-shaped contours on its two lateral edge regions 30, which serve for the form-fitting engagement with the correspondingly oppositely shaped edge regions of the profiles to be connected to one another. At the top of the connecting profile 3, which faces away from each other or connected profiles, the attachment means 35 is integrally formed in the form of a right angle from the surface of the connecting profile 3 upstanding flange, which is reinforced by a likewise one-piece diagonal support. By means of in FIG. 13 indicated by a dashed line glands, the sheet-like door leaf filling 15 is connected to the flange attachment means 35 of the connection profile 3 become. Thus, the connection is mechanically sufficiently strong here, but if necessary indemnify.
