Abstract

The invention relates to a method for producing a post-and-beam connection between a front face of a beam (1) which has a recess (3) and a longitudinal side of a post (2) on which projections (4a, 5; 4b, 5) protrude. The projections (4a, 5; 4b, 5) are thereby inserted into the recess (3) by a relative movement of the beam (1) with respect to the post (2), which runs transverse to the longitudinal side of the beam (1), across an opening (6) in the boundaries of the recess (3), which opening extends from a longitudinal side of the beam (1) into the recess (3). Thereafter, the beam (1) is brought into its intended position with respect to the post (2) by a rotation in a first rotational direction (D1) around a rotational axis (X) extending parallel to its longitudinal axis, wherein the projections (4a, 5; 4b, 5) and the recess (3) are positioned relative to one another such that after the rotation past the projections (4a, 5; 4b, 5) and the boundaries of the recess (3), a form locking is present between the post (2) and the beam (1) in all directions perpendicular to the longitudinal axis of the beam (1) and in the first rotational direction (D1) around the longitudinal axis of the beam (1). By using the method according to the invention, post-and-beam connections can be produced without using additional loose components and/or tools, which post-and-beam connections are form locking in all directions perpendicular to the longitudinal axis of the beam and in a rotational direction around the longitudinal axis of the beam. It is additionally possible to reduce the demands on positional precision during assembly.

Description

Method for producing a mullion-transom connection

TECHNICAL AREA

The invention relates to a method for producing egg ^¬ ner 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 shaped piece for the bar one Such material sets, a fitting for forming such a material set, a mullion-transom connection made with the method and a building facade with a supporting structure of posts and bars with such a mullion-transom connection according to the preambles of the independent claims.

S AND THE TECHNOLOGY

Mullion-transom compounds in the creation of load-bearing structures made of profile elements for use profiles, for example, in the preparation of roof constructions of wooden beams, of storage racks of I-beams or supporting structures for building glass facades of metal ^¬. The end face of a bolt (hori zontal ^¬ element) with the longitudinal side of a post is (comparable tikales 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 bolted to the side of the post. Such a mullion-and-transom connection can be made very stable and can be released again, which is often desired. However, it has the disadvantage that the front side of the bar to Her ^¬ position of the screw has to be exactly within the intended position are positioned at the post, which is often, especially in large and heavy construction ^¬ share is difficult. 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.

From DE 43 13 895 AI is a mullion-transom

Connection is known in which a dovetail-shaped pocket is arranged on the front side of the bolt and on the longitudinal side of the post a corresponding swivel ^¬ Schanz shaped plate. The connection between see the post and the bolt is made by the fact that the bag is driven in a vertical direction over the plate, with a positive connection between the post and the bolt in the direction of gravity and in all horizontal directions is generated. This solution has the advantage that the schwalbenschwanzför ^¬-shaped bag when lowered over the dovetail shaped plate automatically aligns against this plate and that no additional components or tools for producing the compound are required, whereby the assembly is greatly facilitated and no components ver ^¬ can be eaten or lost. Nachtei ^¬ lig here 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 they occurs especially in mullion-transom connections of supporting structures for glass facades, can lead to undefined conditions with local overuse of the connecting components, which can then lead to a Abkip ^¬ pen of the bolt within the compound.

From DE 196 19 862 AI 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 arranged 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 produced by the bolt is moved 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 hä kenartigen element. Then, the latch is lowered, wherein the hook-like element enters the Aufnahmeöff ^¬ tion 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

Direction of gravity and in all horizontal Richtun ^¬ gen. This solution has the advantage that no additional components or tools for making the connection are required, 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 at a lifting of the Rie ^¬ gel from the receiving opening and repealed by the ^¬ ses form fit becomes. Yet a further disadvantage of this solution is the fact that it can come to a tilting of the bolt at a torsional load of the bolt about its longitudinal axis ^¬.

From EP 0967341 A2 a mullion-transom connection is known in which a support element is screwed to the longitudinal side of the post 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 bolt is produced by virtue of the fact that the bolt, transverse to its longitudinal extent, horizes with the open side of its front opening. zontal is pushed onto the support element, 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 pawl 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 also a stable form-fit exists between the post and the bolt in rotation ^¬ direction about the longitudinal axis of the bolt. 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 a backup plate is required for the preparation of the mullion-transom connection, 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 Providing material on Mon ^¬ days place and difficult assembly in difficult situations Si ^¬ tuationen.

PRESENTATION OF THE INVENTION

This raises the problem of providing technical ^¬ specific solutions available that previously the 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-transom connection between a front side 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 off ^¬ recess, said opening of a longitudinal side of the bolt in the recess leads, preferably completely insertable into the recess or, and that then, in the inserted state by a twisting of the bolt in a first rotational direction about an axis parallel to the The axis ^¬ axis of the bolt extending axis of rotation around, the one or more projections and the recess can be so relatively zuein ^¬ other positioned that after twisting a positive connection on the projections or the Be ^¬ limits the recess between the post and the bolt in all directions n is present perpendicular to the longitudinal axis of the bolt and in the first direction of rotation about the longitudinal axis of the bolt 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 projection or projection of the post into the recess of the bolt, the belt is rotated relative to the post about a rotation axis parallel to its longitudinal axis in the first direction of rotation, thereby positioning the projection and the recess relative to each other in that there is a positive connection over the projection (s) and the boundaries of the recess 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. Gleichzei ^¬ tig the latch by twisting in its correct and proper position relative to the post is placed.

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, to which one or more

Protrude projections. 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 projection (s) and the recess are positioned relative to one another such that after twisting over the projection (s) 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 The direction of rotation is around the longitudinal axis of the bolt around.

The method according to the invention makes it possible to produce mullion-transom connections without the use of additional loose components and / or without the use of tools, which are positively in all directions perpendicular to the longitudinal axis of the bolt and in a direction of rotation about the longitudinal axis of the bolt. In addition, by suitable, e.g. funnel-shaped embodiment of the opening or openings, via which the projection or projections are introduced into the recess, can be achieved such that a relatively small positioning accuracy is sufficient during assembly in order to establish the connection.

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

In a further preferred embodiment of the method, the bolt is twisted when rotating relative to the post about an axis of rotation which extends outside the center of the bolt, and preferably in the region of a lateral boundary of the bolt. This has the advantage that it becomes possible to make relatively small angles of rotation the positive connection between the post and the catch in all directions perpendicular to the longitudinal axis of the bolt herzu-, which is particularly large and heavy construction share ^¬ preferred as these in the 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 latches are rotated relative to the post in a second direction of rotation opposite to the first direction of rotation about an axis of rotation parallel to the longitudinal axis of the latch can and is lifted in at least one direction perpendicular to the longitudinal axis of the bolt over the at least one opening in the boundaries of the recess by this rotation of the over the projections or the boundaries of the recess made between the post and the bolt, 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 over 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, is 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. lent, since 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 case 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 make bar connection and thereby bring the latch in its best immunitary 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 post-Ried joint are acted upon about its longitudinal axis 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 farther away from the axis of rotation, substantially with in a second, the first direction opposite n acting direction forces is applied. Here- by making it possible to deliberately load the post in its main load directions, which is preferred in order to minimize its deformation under load.

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 According to an aspect of the invention, the projection (s) which is located farther away are or have overall a greater load capacity than the projection which is closest to the rotation axis.

Preferably, the higher load-bearing capacity is achieved in that a plurality of, preferably identical, projections of the axis of rotation are located farther than the projection which is closest to the axis of rotation and / or in that the projection (s) which are situated further away from the axis of rotation is more load-bearing Attachment to the post 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 results in the possibility that

Carrying capacity to adapt specifically to unbalanced loads, such as. occur when using the mullion-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. In this way, a particularly stable mullion-transom connection can be formed Vierden and the post additionally stabilized by the bolt.

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

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 shaped piece, which forms the recess on the front side of the bolt, is connected by welding to the profile of the bolt Rial ,

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, are bar insertion through the lateral opening completely into the recess and that after this insertion by rotation of the fitting relative to the roller-like body ^¬ possibilities in a first rotational direction about an axis perpendicular to the first outer surface axis of rotation, the roll-like corporealities and the recess derar- tig be positioned relative to each other, that after twisting about the roll-like physical th and the boundaries of the recess is a positive connection between the roller-like Körperlichkeiten and the fitting in all directions in a plane parallel to the first outer surface extending plane 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.

Advantageously, the fitting is formed by a plate-like body, wherein the recess is arranged in one of the two sides of the plate. Such fittings can be produced inexpensively.

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 constitute a material set according to the invention.

As can be seen in conjunction with Figures 2, 4 and 5, which show an exploded view of the mullion-transom connection (Figure 2), a vertical section through the mullion-and-transom connection along the longitudinal axis of the bar 1 at the line passing through AA in Fig. 5 designated point (Fig. 4) and a Vertical section through the mullion-transom connection transverse to the longitudinal axis of the bolt 1 at the point indicated by the line BB in Fig. 4 point (Fig. 5) are on the longitudinal side of the post 2, which faces the latch 1, a kreisringzylindrisches Component 4b fastened with a hexagonal screw 5 and an elongate component 4a with round ends with two hexagonal screws 5, such that these components 4a, 4b 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 elongate member 4a corresponds to the outer diameter of the kreisringzy- lindrischen component 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, according to the claims protrusions formed by the components 4a, 4b and the screws 5 are provided along a direction perpendicular to the longitudinal axis of the post 2 extend ^¬ the line of the longitudinal side of the post 2 from. 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 just ^¬ if 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 molding according to the invention 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 shown in Fig. 3rd 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 to the end face of the steel profile material of the bolt 1 with one of its two plate sides, where it is welded to it, and with its other Plate side the

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 on the longitudinal side of the post 2 by the component 4a and 4b and the

Screws 5 formed projections by a relative movement of the bolt 1 relative to the post 2, which is perpendicular to the longitudinal axis of the bolt 1, from the longitudinal side of the bolt 1 through the opening 6 are completely inserted into the recess 3 and in the reverse manner again from the Recess 3 are removable.

As can be seen in particular from FIG. 5, the recess 3 is also dimensioned such that the protrusions formed on the longitudinal side of the post 2 by the components 4 a and 4 b and the screws 5 can be arranged in the recess 3 such that the bolt 1 assumes its intended position relative to the post 2 and that in the process via 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 Dl (claim first rotational direction) about the longitudinal axis of the bolt 1 around. This situation is shown in FIGS. 1, 4 and 5.

As can also be seen in particular from FIG. 4, the screw heads engage in each case with their flange section 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 assembly of the post 2 and of the bolt 1 to the post-and-bolt connection according to the invention shown in FIGS. 1, 4 and 5 will now be explained with reference to FIGS. 6a to 6f, which illustrate the post-and-bolt connection which is being formed Fig. 1 show in vertical section along the line CC in Fig. 4 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, substantially in a common plane (see Fig. 6a).

Starting from this condition, the bolt 1 is directionally slightly twisted about its longitudinal axis in the illustrated LOOK- clockwise, then on ^¬ send to shifted in the horizontal direction perpendicular to its longitudinal ^¬ axis in the direction of the post 2, thus 4a of the components and 4b and the screws 5 projections formed successively on the opening 6 in the recess 3 in the end face of the bolt 1 is inserted ^¬ leads until they are completely absorbed therein.
