Description

The present invention relates to a connecting element for window and door frames and a profile arrangement.

Connecting elements for window and door frames are already known in principle from the prior art. In particular, window or door frames are assembled due to ease of manufacture and assembly of individual side profiles. These side profiles are connected at their ends, the corners of the frame, creating a frame of two longitudinal profiles and two cross sections. Often, the window area is additionally divided, so that rungs profiles must be connected to inner sides of the longitudinal or transverse profiles. Special fasteners are used to fasten these transom profiles to the longitudinal or transverse profiles.

Modern profile arrangements are usually made of an outer and an inner profile, which are made of aluminum and are connected by means of an insulating web due to their high thermal conductivity. In this way, heat transfer from the inside of the building via the profiles or via the profiles into the interior of the building can be kept as low as possible. Furthermore, profile arrangements of different dimensions are installed in different window systems. In particular, the width of the insulating web, ie the distance between the outer and inner profile of the frame, is varied. Known different connecting elements are thus used for different frames, according to the dimensions of the frame. In this way, a variety of different fasteners for a variety of different profile arrangements are necessary. The variety of parts leads to high production costs, and additional design costs are incurred when introducing new frames. Another disadvantage of conventional fasteners is that they must be mounted with the longitudinal profiles before assembly of the cross sections.

It is therefore the object of the present invention to develop a connecting element of the type mentioned in such a way that this is universally applicable in frame arrangements with different dimensions. At the same time an improvement of the assembly is desirable.

This object is achieved by the subject matter of the independent claims 1 and 14. Advantageous developments are specified in the dependent claims.

Accordingly, the invention particularly relates to a connecting element for window and door frames, which has an insertion element, wherein the insertion element has an insertion region, which is shaped such that it can be inserted into a profile chamber of a transom profile of the window or door frame. Furthermore, the connecting element has a support device which is arranged adjacent to the insertion element. Wherein the support means comprises at least one support portion which is shaped such that it can be inserted into at least one guide rail of the rung profile.

Usually side profiles and rungs profiles are designed as a hollow profiles for maximum heat insulation, the resulting cavity is referred to as a profile chamber.

The advantages of the connecting element according to the invention are in particular that the connecting element is universally applicable by its design. This means that the connecting element is applicable in different window and door frames and / or in window and door frames with different dimensions.

Another point is that the connecting element exerts a supporting function by the support means. Consequently, the stability of the window or door frame in general, and in particular the stability of the rungs profiles on the longitudinal or transverse profiles are improved.

A further advantage of the solution according to the invention is that an improved assembly-suitable design is provided by the support device and in particular by the support region of the support device. Thus, the assembly is facilitated in particular by the at least one guide rail, since it acts as a guide for the entire connecting element during assembly.

In a preferred embodiment of the connecting element according to the invention, the support device has a first and an additional, second support region, wherein each support region is assigned a separate holding region, and wherein the holding regions of the two support regions are preferably connectable to one another such that the support device is fork-shaped. In this context, it is conceivable in particular if the holding region assigned to the first support region has a first length measured in its longitudinal direction, and the holding region assigned to the second support region has a second length again measured in the longitudinal direction thereof, the first and second Length are different. In this way it is possible to select a support device as needed, depending on the distance of the guide rails of the rung profile.

In a further embodiment, it is provided, in particular, that the holding regions assigned to the individual support regions each have a length seen in the longitudinal direction with a center, wherein the support region is in each case arranged decentrally with respect to the center. If, in addition, each holding region has a first end region and an opposite second end region and the first end region of the holding region assigned to the first supporting region is connectable or connected optionally to the first or second end region of the holding region assigned to the second supporting region, the distance between the supporting regions can be variable be set.

According to a further aspect of the invention, it is provided that the support device has at least one holding region and preferably two support regions. The at least one holding region connects the two support regions such that the support device is fork-shaped.

This reinforces the advantages already mentioned and the construction gains additional stability. In addition, the two support areas act relieving on the insertion element, since in a load case, the force is divided.

According to a further aspect of the invention, the insertion element is arranged between the two support areas, so that the connecting element, as seen in the direction of insertion direction of the insertion element, is substantially T-shaped.

As a result, the stability of the construction is improved by the T-shaped arrangement. At the same time, a rotation of the rung profile about an axis which is parallel to the insertion direction of the insertion element is prevented. Furthermore, a wobbling of the rung profile in the profile of the window or door frame can be prevented.

According to a further aspect of the invention, it is provided that the insertion element has a base region, the base region having hooking regions which are shaped complementary to latching regions in a profile of the window or door frame. Preferably, the hooking portions are formed on a first and a second longitudinal side portion of the insert member, wherein the second longitudinal side portion is disposed opposite to the first longitudinal side portion.

This results in particular an optimized attachment or attachment of the insertion element to a profile of the window or door frame. In addition, the Einhakbereiche provide a simple, safe and fast way to mount the connector to the profile of the window or door frame. The arrangement of the hooking regions on opposite longitudinal side regions also prevents wobbling of the connecting element in the frame.

The hooking areas of the base region of the insertion element are in this case particularly preferably designed such that they can be inserted both into the complementarily formed latching regions of the window or door frame and can also be latched by a pivoting movement into the said latching regions. This results in particular in the assembly of the profiles of the window or door frame advantages, since the connecting elements can be mounted on the side profiles both before the assembly of the side profiles and after assembly of the side profiles.

According to a further aspect of the invention, the insertion element of the connecting element further comprises at least one recess on a third longitudinal side region, which is arranged substantially perpendicular to the first two longitudinal side regions. Particularly preferably, the insertion element on the said third longitudinal side region on a plurality of recesses. The at least one recess preferably extends through the insertion element.

This is particularly advantageous because material savings can be achieved in the manufacture of the connecting element through the recess. Consequently, the connecting element becomes cheaper and, on the other hand, weight can be saved. Another significant advantage arises in the heat conduction of the connecting element or the frame assembly, since an additional insulation is provided by the cavities.

According to a further aspect of the invention, it is preferably provided that at least one of the recesses is shaped such that the recess can receive a fastening element.

The additional fixation by means of fastening element, the stability of the frame assembly is improved. In addition, a synergistic effect of the hooking in the Einrastbereichen and the fastener can be achieved. As fasteners offer at this point in particular screws and / or pins.

According to a further aspect of the invention, the insertion element has a bore which extends along a center axis of the insertion element, the central axis of the insertion element extending substantially in the direction, preferably along, of the insertion direction of the insertion element.

By the design of the hole, d. H. The fact that the bore extends through the entire connecting element, a simple mounting option for fasteners is achieved. More specifically, a continuous bore allows, for example, that a screwdriver for fixing the fastener can be passed through the bore.

According to a further aspect of the invention, a fastening element can be guided through at least one region of the bore of the insertion element, wherein the insertion element can be fastened to the profile of the window or door frame, preferably detachably fastened, by means of the fastening element.

This results in particular the advantage that the connecting element can be fixed at a predetermined position on the side profile of the window or door frame. Wherein slipping of the connecting element in the side profile of the window or door frame is prevented. As a result of the fact that the fastening element only has to be inserted in a region of the bore, preferably in an area adjacent to the profile, shorter fastening elements are required overall for fastening. In particular screws or pins are also suitable as fasteners at this point.

According to a further aspect of the invention, the insertion element of the connecting element has an upper region, which is formed opposite the base region. Wherein the upper area has at least one chamfer on at least one side.

As a result, in particular a montagegerechte design of the connecting element is realized. Thus, the chamfered connection element can be more easily inserted into a profile chamber of a transom profile. More specifically, the chamfers are chamfered edges which act as an insertion aid when inserting the connecting element in the profile chamber of the rung profile.

According to a further aspect of the invention, the support device and the insertion element are formed in several parts. Preferably, the support means is formed in two parts.

An advantage which results from such a modular construction is that a complicated production of a one-piece connecting element with complicated geometries is prevented. Also in the assembly advantages are achieved, especially in the two-part design of the support means, since the insertion element is mounted separately from the support means on the profile of the window or door frame.

According to another aspect of the invention, the support portion of the support means comprises an integrally formed sliding block, the sliding block being complementary to a groove in a profile of the window or door frame.

This results in the advantage that in addition to the insertion element and the support means on the profile of the window or door frame is fixed. This improves both the stability of the connecting element and the frame assembly. In addition, the advantageous separate assembly of support means and insertion element is simplified, since all the individual parts of the connecting element independently have a guide.

Furthermore, a profile arrangement is provided. The profile arrangement has at least one outer profile and at least one inner profile, wherein the at least one outer profile and the at least one inner profile are connected to one another by means of at least one insulating web. In addition, the profile arrangement has a connecting element, which can be brought or brought into engagement with the at least one outer profile, wherein the connecting element is preferably a connecting element of a type already described. Preferably, the frame assembly has a further insertion element, which is engageable or brought into engagement with the at least one inner profile, wherein the further insertion element is preferably carried out substantially identical to the previously described insertion elements.

Consequently, the profile arrangement in addition to the actual profiles on both a connecting element and a further insertion element. The advantage of such an arrangement is that the rung profile can be fixed to two locally separate insertion elements. As a result of the fact that the further insertion element is essentially a plug-in element of identical construction, production costs can be saved at this point. At the same time, the insertion element can be replaced or exchanged during assembly, since it is designed to be compatible with both profiles. Thus, the assembly process is made simpler by identical insertion elements.

According to a further aspect of the invention, the profile arrangement further comprises at least one outer transom profile and at least one inner transom profile, wherein the at least one outer transom profile and the at least one inner transom profile are interconnected by means of at least one insulating web. A profile chamber of the outer rung profile accommodates the insertion region of the connecting element and a profile chamber of the inner rung profile accommodates the insertion region of the further insertion element. Preferably, the connecting element is arranged on the outer profile and the further insertion element is arranged on the inner profile.

This results in the advantage that both the outer rung profile is connected by the connecting element with the outer profile, and the inner rung profile is connected by the insertion region of the further insertion element with the inner profile of the window or door frame. As a result, a stable and advantageous fixation of both profiles is achieved.

According to a further aspect of the invention, the at least one further insulating web defines a further profile chamber, wherein the profile chamber of the outer rung profile and the profile chamber of the inner rung profile adjoin the further profile chamber such that the further profile chamber between, preferably centrally between, the professional chambers of the outer rung profile and the inner rung profile is arranged. Furthermore, the three profile chambers are arranged substantially in a row. The insertion region of the connecting element is received exclusively by the profile chamber of the outer transom profile and the insertion region of the further insertion element is received exclusively by the profile chamber of the inner transom profile. By this arrangement, an enlargement or reduction of the profile chamber, which is defined by the further insulating web, without a necessary adjustment of the connecting elements possible. In detail, it is therefore no longer necessary to provide different connecting elements for frame arrangements with different profile chambers defined by the further insulating web.

According to a further aspect of the invention, it is preferably provided that the outer rung profile has at least one guide rail, wherein the at least one support region of the support device of the connection element is inserted or insertable in the at least one guide rail. The outer transom profile preferably has two guide rails for two support regions of the connecting element, wherein the two guide rails are aligned substantially parallel to an extension direction of the profile chambers of the inner transom profile and the outer transom profile.

This design is extremely advantageous for the stability of the frame assembly. At the same time, a twisting of the outer or inner transom profile relative to the outer or inner profile is avoided. The fact that the frame is T-shaped as a whole, the frame assembly is also applicable to forces acting laterally to the insertion direction of the rungs profiles or the connecting element on the rungs profiles applicable.

FIG. 4a and 4b

Views of a modified support means with different distances between the support areas of the support means.

The FIG. 1a to f show a perspective view of a connecting element 100 according to the invention for window and door frames, wherein the connecting element 100 has a push-in element 10 and a support means 20. The insertion element 10 is elongate and extends along a central axis. Furthermore, the insertion element 10 has 4 longitudinal side areas.

The elongated shape of the insertion element 10 in this case positively influences the introduction of force in the component.

Furthermore, the insertion element 10 has a base region 11 and an insertion region 13. Hooking regions 12 are formed on the base region 11, wherein the hooking regions 12a, 12b are arranged on two opposite longitudinal side regions. Furthermore, 10 recesses 16 are formed in the insertion region 13 of the insertion element such that a plurality of passages from a longitudinal side region to an opposite longitudinal side region arise. The recesses 16 are preferably formed on longitudinal side areas, which are arranged substantially perpendicular to the hooking areas 12 having longitudinal side areas.

Furthermore, the insertion region 13 of the insertion element 10 has an upper region 14. This upper region 14 is formed opposite the base region 11. Chamfers 15 are formed on the upper region 14, wherein the chamfers 15 are preferably arranged on opposite longitudinal side regions and particularly preferably on the longitudinal lateral regions which have the hooking regions 12. Alternatively, another number of chamfers 15, preferably 4, may be arranged on the upper region 14.

Furthermore, the insertion element 10 has a bore 18, which is formed along the central axis of the insertion element 10. Preferably, the bore 18 passes through the entire insertion element 10 therethrough.

This is particularly advantageous because the assembly of a fastener 19 is simplified. This fastening element 19 is arranged in a lower region of the bore 18, on the base region 11 of the insertion element 10. Preferably, the fastener 19 may be inserted through one of the recesses 16 first into the insertion member 10 and finally into the bore 18. Thus, at least one of the recesses 16 also facilitates the mounting of the fastening element 19.

The fastening element 19 is preferably a screw, but in principle also pins or rivets are conceivable. Furthermore, the fastening element 19 can also extend through a plurality of recesses 16 or through the entire insertion element 10. Additionally or alternatively, a plurality of fastening elements 19 are conceivable.

The support device 20 of the connecting element 100 has a holding region 21 and a support region 23. In the FIG. 1a to 1f the support means 20 is formed in two parts. In this case, each of the two parts has a holding region 21 and a support region 23. Alternatively, however, it is also conceivable to use a support device with two support regions 23a, 23b and a common holding region 21.

The support portions 23a, 23b are formed sled-shaped, more specifically, they are slat-shaped. Accordingly, the support portions 23a, 23b extend in an extending direction with the side surfaces of the support portions 23a, 23b aligned parallel to the hooking portions 12 having longitudinal side portions of the insertion member 10 wider than the side surfaces of the support portions 23a, 23b which are parallel to the recesses 16 having longitudinal side portions are aligned. Accordingly, the support portions 23a, 23b are formed flat overall.

At the upper region of the support regions 23, ie opposite the holding regions 21a, 21b, the support regions 23 likewise have chamfers 25. These chamfers 25 of the support portions 23 facilitate by their bevel later assembly.

On at least one region of a side surface of the support regions 23, preferably on one of the narrower side surfaces, the support regions 23 have a gradation 24. This gradation 24 also facilitates subsequent assembly or later assembly, since it acts as an introduction aid. In addition, a centering during assembly is achieved by such a gradation. Preferably, a transom profile has a complementary to the step 24 running guide rail 62. Alternatively, the gradations 24 may be formed as a spring, which are insertable into a groove formed on the guide rails complementary groove.

The support region 23 of the support device 20 or the support regions 23a, 23b of the support device 20 adjoin the holding region 21 at a lower region of the support region 23. In this embodiment, the support portion 23 and the holding portion 21 are integrally formed, but in principle, a modular structure is conceivable here.

In addition, the support regions 23a, 23b are arranged or can be arranged adjacent to the insertion element 10. For this purpose, the insertion element 10 has a recess 17 on a longitudinal side region, which has the hooking region 12a. In this recess 17, the support device 20 is to be positioned such that a lower region of the holding region 21 or lower regions of the holding regions 21a, 21b rests or rest on the hooking region 12a of the longitudinal side region.

In addition, the holding regions 21 of the connecting element 100 may have a sliding block 22a, 22b or a slot-shaped surface area. Wherein the sliding block 22a, 22b is preferably formed on a side which is opposite to the arranged on the insertion element 10 side is formed. Particularly preferably, the sliding block 22 is embodied integrally with the holding regions 21. As a sliding block is thus understood in the integral design a kind of spring, which is feasible and / or inserted in a groove. As an alternative to the multipart design of the connecting element 100 already described, it is of course also possible to have an integral overall design.

In the in the FIG. 1a to 1f illustrated embodiments of the connecting element 100 according to the invention, the support means 20, which is formed from two holding portions 21a, 21b and two support portions 23a, 23b, formed fork-shaped. More specifically, the two holding portions 21a, 21b are disposed adjacent to each other such that the sliding block 22a of the first holding portion 21a extends the sliding block 22b of the second holding portion 21b. In a direction perpendicular to the extending direction of the sliding blocks 22, the support portions 23a, 23b extend from the holding portions 21a, 21b, respectively. Thus, the support means 20 is shaped like a two-pronged fork, with the support portions 23a, 23b representing the prongs.

The insertion element 10 is now aligned with the holding regions 21a, 21b of the support device 20 in such a manner that the insertion region 13 of the insertion element 10 is arranged or can be arranged between the support regions 23a, 23b, preferably centrally between the support regions 23a, 23b. Where the male member extends in the same direction as the support portions 23a, 23b. Preferably, the support regions 23a, 23b and the insertion region 13 are flush at their upper ends.

In FIG. 2a to d are different perspective views of a profile arrangement 300 with the connecting element 100 according to the invention FIG. 1 shown. Show more precisely FIG. 2a and 2c the profile assembly 300 in a disassembled state while FIG. 2 B and 2d show the same in an assembled condition. In this case, the profile arrangement 300 consists of a side profile arrangement 310, a rung profile arrangement 320, a connecting element 100 and a further insertion element 10c.

The side profile assembly 310 has an outer profile 30 and an inner profile 40, which are connected by means of insulating webs 50a, 50b due to their high thermal conductivity. As a result, a heat transfer from the building interior over the profiles is kept as low as possible.

Further, the outer profile 30 normally forms the Fasadenseitigen completion of the fixed part of a window or door frame, and the inner profile accordingly the inside-side fixed part of the said frame.

The rung profile 320 has a comparable structure. Thus, the transom profile 320 consists of an outer transom profile 60, an inner transom profile 70 and connecting further insulating crosspieces 90a, 90b. The outer transom profile 60 and the inner transom profile 70 have associated profile chambers 61 and 71. In addition, a further profile chamber 91 is formed or defined by the insulating webs 90a and 90b.

Preferably, the profiles 30, 40, 60 and 70 are made of metal, in particular aluminum, whereas the insulating webs 50 and 90 are made of heat-insulating material, such as plastic material.

The connecting element 100 is arranged on the outer profile 30. In this case, the hooking regions 12b of the base region 11 of the connecting element 100 are brought into engagement with complementarily formed latching regions 31 of the outer profile 30.
The insertion element 10 itself can either be pushed onto the outer profile 30 for mounting or be attached by a pivoting movement.

In addition, a fastener 19 can fix the position of the male member 10 on the outer profile 30.

The support means 20 of the connecting element 100 is also attached to the outer profile 30. More specifically, the sliding block 22 of the holding portion 21 or the sliding blocks 22a, 22b of the holding portions 21a, 21b are brought into engagement with a complementarily formed groove 32 of the outer profile 30. This can also be realized by a sliding operation as well as by a pivoting operation.

Thus, preferably, the male member 10 and the support means 20 are each separately attached to the outer profile 30 attachable. This offers the advantage that during assembly first the insertion element 10 is mounted or can be mounted and in a next step, the support means 20 can be mounted or mounted. More specifically, a first part of the support means 20 having the holding portion 21a and the support portion 23a is projected from a first side and a second portion of the support 20 having the holding portion 21b and the support portion 23b from a second side in the direction of pushed insert element 10 pushed. In this case, the two parts of the support device 20 are preferably pushed so far that touch the holding portions 21 a, 21 b behind the push-in element 10. Thus, the male member 10 is supported on one longitudinal side by the hooking portion 12b by the complementarily formed latching portions 31 of the outer profile 30 and supported on the opposite longitudinal side by the hooking portion 12a of lower portions of the holding portions 21a, 21b.

On the inner profile 40 of the side profile arrangement 310, a further insertion element 10c, which is substantially identical in construction to the insertion element 10 of the connecting element 100, is arranged. Hooking portions 12c, 12d of the base portion 11c of the male member 10c are engaged with complementarily formed snap portions 41 of the inner profile 40. The further insertion element 10c can also be attached to the inner profile 40 by a sliding movement as well as by a pivoting movement.

Furthermore, the further insertion element 10c has a fastening element 19, with which a further fixation on the inner profile 40 is achieved.

The insertion element 10 of the connecting element 100 and the further insertion element 10c are preferably arranged opposite each other. Wherein the further insertion element 10c, in contrast to the insertion element 10 has no adjacent support means 20.

The basic construction of the side profile arrangement 310 is comparable to that of the rung profile arrangement 320 already described. Thus, the outer profile 30 and the inner profile 40 of the side profile assembly 310 also form profile chambers. In addition, a further profile chamber is formed by the insulating webs 50a and 50b, wherein the profile chamber of the outer profile 30 and the profile chamber of the inner profile adjacent to the profiled chamber formed by the Isolierstegen 50 such that the formed profile chamber between, preferably centrally between, the profile chambers of the outer profile 30 and the inner profile 40 is arranged. Thus, the three profile chambers form a row. In addition, if the side profile arrangement 310 is a longitudinal profile arrangement, the profile chambers are formed in a horizontal profile extension plane, the plane intersecting the profile chambers in the middle. Accordingly, if the side profile assembly 310 is a transverse profile arrangement, the profile chambers are formed in a vertical profile extension plane, the plane intersecting the profile chambers centrally. In both arrangements, the insertion elements 10, 10c now extend exactly in the direction of a normal of the profile extension plane. The insertion elements 10, 10c thus point in a direction perpendicular to the side profile assembly 310, preferably, they point in the direction of a window inside.

FIG. 2 B and 2d show the profile assembly 300 in an assembled form. In this case, the connecting element 100 and the push-in element 10c, as already described, are arranged or fastened to the side profile arrangement 310.

The transom profile arrangement 320, consisting of the outer transom profile 60, the inner transom profile 70 and the further insulating crosspieces 90, is pushed or pushed during assembly onto the insertion elements 10 and 10c.

As already described, the outer transom profile 60 has the profiled chamber 61 and the inner transom profile 70 has the profiled chamber 71. Furthermore, the further profile chamber 91 is defined by the insulating webs 90a and 90b. The profile chambers 61 of the outer rung profile 60 and the profile chamber 71 of the inner rung profile 70 adjoin the further profile chamber 91 such that the further profile chamber 91 is arranged between the profile chambers 61, 71 of the outer rung profile 60 and the inner rung profile 70. Preferably, the further profile chamber 91 is arranged centrally between the said profile chambers 61, 71. Furthermore, the three profile chambers are arranged in a row or line.

The insertion elements 10 and 10c are designed such that the insertion region 13 of the connecting element 100 is received by the profile chamber 61 of the outer rung profile 60 and the insertion region 13c of the further insertion element 10c is received by the profile chamber 71 of the inner rung profile becomes. Respectively the profile chambers 61, 71 are adapted to such a recording.

In particular, the insertion region 13 of the connection element 100 is received exclusively by the profile chamber 61 of the outer rung profile 60 and the insertion region 13c of the further insertion element 10c is received exclusively by the profile chamber 71 of the inner rung profile 70.

In this way, the further profile chamber 91, which as already described is formed by the insulating webs 90a and 90b, does not have any push-in element 10, 10c and also no area or part of the push-in element 10, 10c or the connecting element 100. In other words, the connecting element 100 or the push-in element 10c is currently designed in such a way that fastening or attachment to the rung profile arrangement 320 is made possible without contact or intervention with the further profile chamber 91.

This results in particular in the advantage that the dimensions of the further profile chamber 91 can be changed without adapting the connecting element 100 or the further push-in element 10c. Consequently, the width of the insulation can be changed with the same insertion elements 10, 10c. This offers the advantage that with different frame arrangements, identical connection elements 100 or insertion elements 10, 10c can nevertheless be used or used.

The outer profile bar 60 is formed from a direction of insertion of the connecting element 100 seen substantially T-shaped. It follows that the rung profile arrangement 320 viewed from the same direction has a T-shape. The T-shape results from the fact that the outer transom profile 60 has two guide rails 62, which are aligned substantially perpendicular to the extension direction of the profiled chambers 61, 71. The extension direction of the profile chambers 61, 71 in this case points in the same direction as the insertion direction of the connecting element 100.

The two guide rails 62 are adapted to receive the support means 20. More specifically, the support portions 23a, 23b of the support 20 are received. In this case, the gradation 24 of the support regions 23a slide, 23 b, preferably in a groove formed by the two guide rails 62.

In the assembled state of the profile arrangement 300, only parts of the support device 20 are visible.

The FIG. 3a and 3b show a front view of a profile assembly 300 with connecting element 100 according to the invention in an assembled and a disassembled state.

The outer profile 30 has a latching region 31, which engages with the hooking region 12b of the connecting element 100. Furthermore, the outer profile 30 is additionally engaged via a groove 32 with the support means 20 of the connecting element 100 in engagement.
