Description

TECHNICAL AREA

The invention relates to a method for producing a mullion-transom connection between the end face of a bolt and a longitudinal side of a post, a material set for producing a mullion-transom connection with the method, a fitting for the bolt of such a material set , a fitting for forming such a material set, a mullion-transom connection made with the method and a building facade with a supporting construction of posts and bars with such a mullion-transom connection according to the preambles of the independent claims.

STATE OF THE ART

Mullion-and-transom connections are used in the construction of support structures of profile elements, e.g. in the construction of roof structures made of wooden beams, of storage shelves of T-beams or of supporting structures for building glass facades of metal profiles. In this case, the end face of a bolt (horizontal element) is connected to the longitudinal side of a post (vertical element). For this purpose, various solutions are known from the prior art.

In a first known mullion-transom connection, the end face of the bolt is screwed to the side of the post. Such a mullion-transom connection can be made very stable and is detachable, which is often desired. However, it has the disadvantage that the end face of the bolt for the preparation of the screw must be positioned exactly in the intended position on the post, which is often difficult, especially for large and heavy components. In addition, loose components, such as Screws and nuts, as well as associated tools needed, which can lead to errors in the material supply at the assembly site and the assembly in difficult situations, such as on a scaffold, significantly more difficult. document KR 2011 0011154 A discloses all features of the preamble of claims 4 and 21. From DE 43 13 895 A1 is a mullion-transom connection is known in which on the front side of the bolt a dovetail-shaped pocket and on the longitudinal side of the post, a corresponding dovetail-shaped plate is arranged. The connection between the post and the bar is made by driving the bag vertically over the plate creating a positive fit between the upright and the bar in the direction of gravity as well as in all horizontal directions. This solution has the advantage that the dovetail-shaped pocket automatically aligns with this plate when lowering over the dovetail-shaped plate and that no additional components or tools for making the connection are required, whereby the assembly is much easier and no components can be forgotten or can be lost. The disadvantage here, however, is the fact that in the direction opposite to the direction of gravity no positive connection between the post and the bolt, so that the connection is lifted when lifting the bolt and it at a torsional load of the bolt around its longitudinal axis around, as in particular Post-and-beam connections of glass façade support structures may occur, causing undefined conditions with local overstress of the connection components, which may then result in tipping of the latch within the connection.

Out DE 196 19 862 A1 is a mullion-transom connection is known, in which on the longitudinal side of the post, a plate with a hook-like element is arranged and on the front side of the bolt a recess with an upwardly directed receiving opening for the hook-like element. The connection between the post and the bolt is made by the bolt is driven with its front-side recess in the horizontal direction over the plate with the hook-like element until the receiving opening is located above the hook-like element. Then, the latch is lowered, wherein the hook-like element enters the receiving opening and the latch rests with the boundaries of the recess on the plate. This creates a positive connection between the post and the bolt in the direction of gravity and in all horizontal directions. This solution has the advantage that no additional components or tools are required for the preparation of the connection, whereby the assembly is facilitated because no components can be forgotten or lost. The disadvantage here, however, that the end face of the bolt for inserting the hook-like element in the receiving opening must be positioned exactly on the post. Also disadvantageous here is that in the direction contrary to the direction of gravity in the intended attachment situation no positive connection between the post and the bolt so that the hook-like element exits when lifting the bolt from the receiving opening and the generated by this positive engagement is canceled. Yet another disadvantage of this solution is the fact that tilting of the bolt can occur when the bolt is torsionally loaded about its longitudinal axis.

Out EP 0967341 A2 is a mullion-transom connection is known in which on the longitudinal side of the post, a support member is screwed and on the front side of the bolt, an opening with a partially corresponding shape is present, which is open to a longitudinal side of the bolt. The connection between the post and the latch is made by the latch being horizontal transversely to its longitudinal extent with the open side of its frontal opening is pushed onto the support member until it is arranged completely in the frontal opening. Then, the latch is lowered until the boundaries of the frontal openings rest on the support element. This results in a positive connection between the post and the bolt in the direction of gravity and in the horizontal directions transverse to the longitudinal direction of the bolt. Subsequently, a locking plate is inserted from the open side of the front opening of the bolt forth in a gap formed between the lower boundary of the opening and the support element, which then in the intended attachment situation then also a positive connection between the post and the bolt in the direction opposite to the direction of gravity manufactures. This solution has the advantage that the sliding of the bolt with its frontal opening on the support member and the subsequent lowering of the same no particularly accurate positioning between the post and the latch is required, and that after inserting the backup plate and a stable positive connection between the Post and the latch in the rotational direction about the longitudinal axis of the bolt is present. The disadvantage here, however, is the fact that in the longitudinal direction of the bolt pointing away from the post no positive connection between the post and the bolt. Another disadvantage is that for the production of the mullion-transom connection a backup plate is required, which can be installed only after the intended arrangement of the bolt on the post and until then must be kept as a loose item, which also leads to errors in the Material supply can lead to the assembly site and difficult assembly in difficult situations.

PRESENTATION OF THE INVENTION

It is therefore the task of providing technical solutions that the previously mentioned disadvantages of the prior art do not have or at least partially avoid.

This object is solved by the subject matters of the independent claims.

According to these, a first aspect of the invention relates to a method for producing a mullion-and-transom connection between an end face of a bolt and a longitudinal side of a post.

For this purpose, a post is provided, which has on its longitudinal side to be joined to the bolt one or more projections, which preferably project perpendicularly from this longitudinal side, and a bolt which has a recess on its end face to be connected to the post.

The projecting from the longitudinal side of the post projections and the recess on the end face of the bolt are coordinated such that the one or more projections by a relative movement of the bolt relative to the post, which transversely, preferably perpendicular to the longitudinal axis of the bolt extends over at least an opening in the boundaries of the recess, which opening leads from a longitudinal side of the bolt into the recess, preferably completely inserted into the recess or are and then that in the inserted state by a rotation of the bolt in a first direction of rotation about a longitudinal axis of the Riegel's rotating axis of rotation, which or the projections and the recess can be positioned relative to each other such that after twisting a positive connection over the projections or the boundaries of the recess between the post and the bolt in all directions perpendicular to Longitudinal axis of the bolt and in the first direction of rotation about the longitudinal axis of the bolt is present and the bolt assumes its intended position relative to the post.

To the inventive connection between the provided post and the provided To produce bars, the or the projections of the post is inserted through the opening or the openings in the recess on the front side of the bolt, which is accomplished by a relative movement between the post and the bolt transversely, preferably perpendicular to the longitudinal axis of the bolt. In this case, the projection or projections are preferably completely received in the recess.

After inserting the protrusion of the post into the recess of the bolt, the bolt is rotated relative to the post about a rotation axis parallel to its longitudinal axis in the first rotational direction, thereby positioning the protrusion and the recess relative to each other there is a positive engagement over the projection (s) and the boundaries of the recess between the post and the latch in all directions perpendicular to the longitudinal axis of the latch and in the first direction of rotation about the longitudinal axis of the latch. At the same time the bolt is brought by twisting in its intended position relative to the post.

In other words, the first aspect of the invention relates to a method for producing a mullion-and-transom connection between an end face of a latch having a recess and a longitudinal side of a post on which one or more protrusions protrude. In this case, the projection or projections by a relative movement of the bolt relative to the post, which extends transversely, preferably perpendicular to the longitudinal axis of the bolt, via at least one opening in the boundaries of the recess, which opening leads from a longitudinal side of the bolt in the recess with advantage completely inserted into the recess. Then, the bolt is brought by turning it about a parallel to its longitudinal axis extending axis of rotation in a first direction of rotation in its intended position relative to the post, wherein the one or more projections and the recess are positioned relative to each other such that after twisting over the one or more projections and the boundaries of the recess a positive connection between the post and the bolt in all directions perpendicular to the longitudinal axis of the bolt and in the first direction of rotation the longitudinal axis of the bolt is present.

The inventive method can be without the use of additional loose components and / or without the use of tools post-bolt connections produce, which are positively in all directions perpendicular to the longitudinal axis of the bolt and in a rotational direction about the longitudinal axis of the bolt around. In addition, by suitable, e.g. funnel-shaped, embodiment of the opening or openings, over which the projection or projections are introduced into the recess, can be achieved, that during assembly a relatively low positioning accuracy is sufficient to produce the connection.

In a preferred embodiment of the method, the relative movement between the post and the latch for inserting the projection or projections in the recess is rectilinear or along an arcuate or kinked Linienzugs. Such relative movements are easy to implement even with large or heavy components.

In a further preferred embodiment of the method, the bolt is rotated during rotation relative to the post about a rotation axis which extends outside the center of the bolt, and preferably in the region of a lateral boundaries of the bolt. This results in the advantage that it is possible with relatively small angles of rotation to make the positive connection between the post and the bolt in all directions perpendicular to the longitudinal axis of the bolt, which is particularly preferred for large and heavy components, as these during assembly, eg With a crane, are not arbitrarily rotatable about its longitudinal axis.

A second aspect of the invention relates to a material set for producing a mullion-transom connection with the method according to the first aspect of the invention. The set comprises a post, which has on its longitudinal side to be joined to the bolt one or more projections, which protrude in particular perpendicularly from this longitudinal side, and a bolt which has a recess on its end face to be connected to the post. The projecting from the longitudinal side of the post projections and the recess on the end face of the bolt are coordinated such that the one or more projections by a relative movement of the bolt relative to the post, which transversely, preferably perpendicular to the longitudinal axis of the bolt extends over at least an opening in the boundaries of the recess, which opening leads from one longitudinal side of the bolt into the recess, is preferably completely inserted into the recess or are, and that then in the inserted state by a rotation of the bolt in a first direction of rotation about a longitudinal axis the pivot extending axis of rotation, the one or more projections and the recess can be positioned relative to each other such that after twisting a positive fit over the one or more projections and the boundaries of the recess between the post and the bolt in all directions perpendicular to Longitudinal axis of the bolt and in the first direction of rotation about the longitudinal axis of the bolt is present and the bolt assumes its intended position relative to the post.

Such material sets represent preferred commercial forms of the invention.

Preferably, the projections on the longitudinal side of the post and the recess on the front side of the bolt are designed such that, after a Producing the mullion-transom connection with the material set according to the invention while carrying out the method according to the first aspect of the invention, the latch can be rotated in a second, opposite to the first direction of rotation about a parallel to the longitudinal axis of the bolt axis of rotation relative to the post and by this twisting of the over the projections or the projections and the boundaries of the recess made positive connection between the post and the bolt in at least one direction perpendicular to the longitudinal axis of the bolt on the at least one opening in the boundaries of the recess is canceled, so that the one or more projections by a relative movement of the bolt relative to the post, which transversely, preferably perpendicular to the longitudinal axis of the bolt, can be extended via the at least one opening from the recess or can, for the abolition of the mullion-transom connection. This results in the advantage that the mullion-transom connection can be canceled again in a simple manner, preferably without tools and advantageously by reversing the processes used to produce them.

In a preferred embodiment of the material set, the projections on the longitudinal side of the post and the recess on the front side of the bolt are designed such that the one or more projections by the relative movement of the bolt relative to the post via exactly one opening in the boundaries of the recess, which of one longitudinal side of the bolt leads into the recess, preferably completely inserted into the recess or are. In this way, a longitudinal side of the bolt only at one point have an opening, resulting in the advantage that the actual locking contour is only slightly disturbed and the inventive post-tie connection is largely hidden and invisible. Also, this construction allows particularly stable connections, because the boundaries of the recess need only be interrupted at one point, resulting in structural advantages.

In a preferred embodiment of the material set, the projections on the longitudinal side of the post and the recess on the end face of the bolt are designed such that the projection or projections by a relative movement of the bolt relative to the post, which is rectilinear or along an arcuate or kinked Linienzugs transversely, preferably perpendicular to the longitudinal axis of the bolt, can be introduced via the opening or the openings in the recess. In particular, in the event that the material set is formed by large and heavy components, there is the advantage that the assembly is facilitated, since such relative movements are easy to implement even with such components.

Preferably, the projection or projections on the longitudinal side of the post and the recess on the front side of the bolt are designed such that the axis of rotation about which the bolt can be rotated after insertion of the projection or projections in the recess in the first direction of rotation around the posts To produce latch connection and bring the bolt in its intended position relative to the post, outside the center of the bolt extends, preferably in the region of a lateral boundary of the bolt. As already mentioned, this is particularly advantageous for large and heavy components (in particular bars), because such components are not arbitrarily rotatable about their longitudinal axis during assembly and here the positive connection between the post and the bolt in all directions perpendicular to the longitudinal axis of the Bolt can be made with relatively small twist angles of the bolt.

Stand from the long side of the post from several projections, by means of which by making the Post-tie connection of the positive connection between the post and the bolt can be made in all directions perpendicular to the longitudinal axis of the bolt, so there is the advantage that these projections at a torsional load (rotational load) of the bolt of the mullion-transom connection to his Longitudinal axis are acted upon only acting in a direction perpendicular to the longitudinal axis of the bolt forces but not with a torque, which significantly simplifies their design, dimensioning and attachment to the post. If these projections are arranged along a line extending substantially perpendicular to the longitudinal axis of the post, which is preferred, it is a further advantage that an embodiment of the material set is such that insertion of the projections over the opening or the openings into the recess by a rectilinear relative movement of the bolt relative to the post is possible, is favored.

In the case of material sets in which the axis of rotation extends outside the middle of the bolt and protrude from the longitudinal side of the post several projections, it is further preferred that the projections on the longitudinal side of the post and the recess on the end face of the bolt are designed in this way in that after the mullion-and-transom connection between the mullion and the latch has been made by the method according to the first aspect of the invention, the projection closest to the axis of rotation acts on the latch with a torque (rotary load) acting in the first rotational direction about the longitudinal axis of the bolt around, is acted upon substantially in a first direction, preferably acting in the longitudinal direction of the post forces, while at least one further projection, which is located further away from the axis of rotation substantially with in a second R opposite the first direction acting acting forces. hereby makes it possible to load the post targeted in its Hauptlastrichtungen, which is preferred in order to minimize its deformation under load as possible.

It is further preferred that the projections on the longitudinal side of the post and the recess on the front side of the bolt are designed such that after a production of the mullion-transom connection between the post and the bolt with the method according to the first aspect of Invention, the projection or projections, which or which of the rotation axis is located more remote or have a total of a higher carrying capacity or have than the projection which is closest to the axis of rotation.

Preferably, the higher load-bearing capacity is achieved by having a plurality of, preferably identical, projections of the axis of rotation located farther than the projection which is closest to the axis of rotation and / or by the projection (s) located more remote from the axis of rotation providing a more stable connection the post has or have as the projection which is closest to the axis of rotation. This can be realized for example by a larger number of attachment points of the projections on the post.

This gives rise to the possibility of specifically adapting the carrying capacity to asymmetrical loads, as described, for example, in US Pat. occur when using the mullion-and-transom connection to form a support structure for a building facade.

Advantageously, the projection or projections are connected by screwing to the post. As a result, the production of material sets according to the invention is significantly simplified.

Preferably, the one or more projections on the longitudinal side of the post and the recess on the front side of the bolt are designed such that after the production of the mullion-transom connection between the post and the latch with the method according to the first aspect of the invention over the projection or the boundaries of the recess, in addition to the positive connection between the post and the latch in all directions perpendicular to the longitudinal axis of the bolt and in the first direction of rotation about the longitudinal axis of the bolt around, there is also a positive connection between the post and the bolt in the direction away from the post longitudinal direction of the bolt. As a result, a particularly stable mullion-transom connection can be formed and the post additionally stabilized by the latch.

It is further preferred that the projections on the longitudinal side of the post are at least partially formed by screws screwed into the post and that the positive connection between the post and the latch in the longitudinal direction of the bolt facing away from the post from the heads of the screws and the boundaries the recess is formed. As a result, such a material set can be made available particularly cost-effectively.

Advantageously, the projections on the longitudinal side of the post and the recess on the front side of the bolt are designed such that the production of the mullion-transom connection between the post and the latch with the method according to the first aspect of the invention without the use of tools and / or can be done without the use of additional components. This makes assembly easier, especially when mounting under difficult conditions, e.g. from a scaffold.

In yet another preferred embodiment of the material set, the recess in the end face of the bolt is formed by an advantageously one-piece molded piece, which is preferably made of metal.

It is further preferred that the post and the bolt are each formed from a profile material, preferably made of metal, and that the fitting, which forms the recess on the end face of the bolt, is connected by welding to the profile material of the bolt.

Preferably, the fitting thereby forms the entire end face of the bolt.

The latter measures make it possible to provide high-quality material sets according to the invention cost-effectively.

A third aspect of the invention relates to a fitting for the bolt of a material set according to the second aspect of the invention. This comprises or consists of a body, advantageously of metal, which has a substantially planar first outer surface, in which a recess is arranged, which preferably has a substantially uniform depth. This recess opens via a lateral opening into a second outer surface of the body adjoining the first outer surface at an angle of preferably 90 °.

The recess is designed in such a way that two, preferably identical, roller-like bodies arranged with a fixed spacing, whose longitudinal axes run parallel to one another and perpendicular to the first outer surface, are moved relative to the shaped piece, which takes place in a plane parallel to the first outer surface, can be inserted completely into the recess via the lateral opening and that, after this insertion, the roll-like body and the recess can be positioned relative to one another in a first direction of rotation about a rotation axis running perpendicularly to the first outer surface by rotating the shaped piece relative to the roll-like bodies. that after twisting about the roll-like physicalities and the boundaries of the recess form a positive fit between the roller-like bodies and the fitting in all directions in a plane parallel to the first outer surface and in the first direction of rotation. With the fitting according to the invention, bars for material sets according to the second aspect of the invention can be produced in a simple manner.

Preferably, the recess has undercuts into which radial protrusions formed on the roll-like body may engage to create a positive fit between the roller-like bodies and the boundaries of the recess in a direction perpendicular to the first outer surface of the body. With such fittings can be produced in a simple manner inventive material sets according to the second aspect of the invention, in which after the production of the mullion-transom connection between the post and the bolt with the method according to the first aspect of the invention on the radial projections the roller-like Körperlichkeiten and the undercuts of the recess, in addition to the positive connection between the post and the bolt in all directions perpendicular to the longitudinal axis of the bolt and in the first direction of rotation about the longitudinal axis of the bolt around, also a positive connection between the post and the bolt in the From the post-pointing longitudinal direction of the bolt is present. As already mentioned, such a particularly stable mullion-transom connection can be formed and the post additionally stabilized by the latches.

Furthermore, the fitting comprises a second fitting part, which has a body which has a substantially planar first outer surface. In this outer surface, a recess of preferably substantially uniform depth is arranged, which opens via a lateral opening into a second outer surface of the body adjoining the first outer surface at an angle of preferably 90 °. In this case, the first and the second fitting part are coordinated or formed such that by fastening the first fitting part with the mounting plate on a longitudinal side of a post, such that the projection or projections protrude from the longitudinal side of the post, and by attachment of the second fitting part On a bolt, such that the first outer surface of the second fitting part at least partially forms the end face of the bolt, a material set according to the second aspect of the invention is formed.

WAYS FOR CARRYING OUT THE INVENTION

Fig. 1 shows an inventive mullion-transom connection of a supporting structure for a building glass facade in a perspective plan view. There are only sections of the post 2 and the bolt 1, with which the mullion-transom connection is formed, respectively. The post 2 and the bolt 1 together represent a material set according to the invention.

As in synopsis with the Figures 2 . 4 and 5 which shows an exploded view of the mullion-transom connection ( Fig. 2 ), a vertical section through the mullion-transom connection along the longitudinal axis of the bolt 1 at the through the line AA in Fig. 5 show designated point ( Fig. 4 ) and one Vertical section through the mullion-transom connection transverse to the longitudinal axis of the bolt 1 at the line BB in Fig. 4 show designated point ( Fig. 5 ), are on the long side of the post 2, which faces the latch 1, a kreisringzylindrisches component 4 b fixed with a hexagonal bolt 5 and an elongated member 4 a with round ends with two hexagon screws 5, such that these components 4 a, 4 b and these passing through screws 5 project perpendicularly from this longitudinal side. They form in this way claims according to claims 4a, 5; 4b, 5. The height of the elongated member 4a corresponds to the outer diameter of the annular cylindrical member 4b and the curves of its two ends have a radius which corresponds to the radius of the outer diameter of the annular cylindrical member 4b. The three screws 5 are identical and penetrate along a perpendicular to the longitudinal axis of the post 2 line in the post 2 a. Accordingly, the claimed projections formed by the components 4a, 4b and the screws 5 project along a line running perpendicular to the longitudinal axis of the post 2 from the longitudinal side of the post 2. The heads of the screws 5 have on their side facing the screw shaft each have a flange portion which projects radially beyond the screw shaft and the hexagon of the screw head. The actual post 2 is made of a galvanized steel profile material, and the components 4a, 4b and the screws 5 are also made of galvanized steel.

Also, the bolt 1 is made of a galvanized steel profile material, on whose the post 2 facing end side a one-piece according to the invention molding 7 made of steel by welding with the profile material is attached. As can be seen, the molding 7 forms the entire end face of the bolt first

A perspective top view of the post 2 facing side of the molding 7 is in Fig. 3 shown. As can be clearly seen in conjunction with this figure, the molding 7 is formed by a rectangular plate-like body which is adjacent with one of its two sides of the sheet of the steel profile material of the bolt 1, where it is welded thereto, and with its other side of the plate Post 2 faces. The outer surface 8 of the post 2 facing plate side of the molding 7 is perpendicular to the longitudinal axis of the bolt 1 and has a recess 3 of uniform depth, which opens via a side opening 6 in a longitudinal side of the bolt 1. The lateral opening 6 and the recess 3 are dimensioned such that the protrusions formed on the longitudinal side of the post 2 by the component 4a and 4b and the screws 5 by a relative movement of the bolt 1 relative to the post 2, which perpendicular to the longitudinal axis of the bolt. 1 runs, from the longitudinal side of the bolt 1 through the opening 6 are completely inserted into the recess 3 and in the reverse manner are removable from the recess 3 again.

As in particular from Fig. 5 can be seen, the recess 3 is also dimensioned such that the protrusions formed on the longitudinal side of the post 2 by the components 4a and 4b and the screws 5 can be arranged in the recess 3 such that the bolt 1 its intended position relative to the post 2 occupies and that while about these projections 4a, 5; 4b, 5 and the boundaries of the recess 3 is a positive connection between the post 2 and the bolt 1 in all directions perpendicular to the longitudinal axis of the bolt 1 and a rotational direction D1 (claim first rotational direction) about the longitudinal axis of the bolt 1 around. This situation is in the FIGS. 1 . 4 and 5 shown.

As in particular from Fig. 4 can be seen further, engage behind the screw heads each with its flange undercuts 10 of the recess, whereby in addition over the protrusions 4a, 5 formed on the longitudinal side of the post 2; 4b, 5 and the boundaries of the recess 3 is a positive connection between the post 2 and the latch 1 in the away from the post 2 longitudinal direction of the bolt 1 is present.

The joining of the post 2 and the bolt 1 to the in the FIGS. 1 . 4 and 5 shown inventive mullion-transom connection will now be based on the FIGS. 6a to 6f explains, which is in the development of the post-and-bolt connection according to Fig. 1 in vertical section along the line CC in Fig. 4 show in different stages of emergence.

As can be seen, for this purpose, the bolt 1 is placed in a horizontal orientation such side of the vertically aligned post 2, that its longitudinal axis is parallel to the longitudinal axes of the screws 5, that its longitudinal side, in which the opening 6 opens, opposite to that projection, which is formed by the annular cylindrical member 4b and one of the screws 5 and that its front side and the longitudinal side of the post 2, which the projections 4a, 5; 4b, 5 carries, essentially in a common plane (see Fig. 6a ).

Starting from this state, the bolt 1 is slightly rotated clockwise around its longitudinal axis in the illustrated viewing direction and then moved in the horizontal direction perpendicular to its longitudinal axis in the direction of the post 2, whereby the components 4a and 4b and the screws. 5 formed projections are successively inserted through the opening 6 in the recess 3 in the end face of the bolt 1 until they are completely received therein. In this case, the end face of the bolt 1 is brought into abutment with the longitudinal side of the post 2, which the projections 4a, 5; 4b, 5 carries (see in succession the Figures 6b, 6c and 6d ). The screw head of that screw 5, with which the annular cylindrical component 4b on Post 2 is fixed, engages behind the undercuts 10 of the recess 3 and the circular cylindrical member 4 b and / or the head of the fixing screw 5 are at the right end of the recess 3 at the limits thereof.

Starting from the in Fig. 6d As shown, the bolt 1 is then rotated about the longitudinal axis X of the screw 5, with which the annular cylindrical member 4 b is fixed to the post 2, in the direction of view in a direction of rotation D1 counterclockwise (claim first rotational direction) until it is its intended Position opposite the post 2 occupies, in which its upper side in the direction perpendicular to its longitudinal axis is horizontal (see the succession FIGS. 6e and 6f ). The screw heads of those screws 5 with which the elongated component 4a is attached to the post 2 then also engage behind, the undercuts 10 of the recess 3 and the left end of the elongate component 4a and / or the head of its left fastening screw 5 are at the left end the recess 3 at the boundaries of.

The in Fig. 6f shown state corresponds to the in the FIGS. 1 . 4 and 5 illustrated situation. In this state is above the projections 4a, 5; 4b, 5 and the boundaries of the recess 3 a positive connection between the post 2 and the bolt 3 in all directions perpendicular to the longitudinal axis of the bolt 1 and in the rotational direction D1 about the longitudinal axis of the bolt 1 around. In addition, over the projections 4a, 5; 4b, 5 or the heads of the screws 5 and the boundaries of the recess 3 also a positive connection between the post 2 and the bolt 1 in the direction away from the post 2 longitudinal direction of the bolt 1 before.

To produce the inventive mullion-transom connection as described above, it requires no tools or additional components, and it can in reverse order of action is reversed.

While preferred embodiments of the invention are described in the present application, it should be clearly understood that the invention is not limited to these and may be practiced otherwise within the scope of the following claims.
