Description

Field of the invention

The present invention relates to posts and bars for window or door frames or z. For example, a mullion and transom construction (for example, for a framework of a facade) and in particular a compound of such posts and bars.

Background of the invention

Posts and bars, as used in window and door frames and frameworks for facades, are usually separate components that are to be joined together. This is done for example in posts and bars made of wood by means of wooden dowels, which are pressed into holes of each other to be connected posts and bars and / or glued. It is desired that gaps between connecting surfaces of posts and bars are avoided and completely touch the connection surfaces. Further, it is desirable that act between connecting surfaces of posts and bars forces, press the connecting surfaces against each other or provide a bias between the posts and bars to connect these joints without joints.

For this purpose, for example, post-and-bolt connections are used, in which metal threaded inserts are arranged in bores of a wooden post and are screwed into these connecting pins. The connecting pins have heads at their free ends. In the bolt bores for receiving the connecting pins are arranged starting from the surface provided for connection to the post. Perpendicular to these holes bores are arranged in the latch, which are each in communication with a bore for receiving a connecting pin and in which extends in the assembled state, the head of a connecting pin. In these holes eccentric elements are arranged, which receive the heads of the connecting pins. Upon rotation of the eccentric elements forces are exerted on the heads of the connecting pins, which bias the bolt and the post against each other. It is disadvantageous that the holes in the bolt for receiving the eccentric elements must have a large diameter, which is usually in the range between 15 and 25 mm. This is necessary to accommodate eccentric elements with dimensions that provide a desired bias during rotation. To avoid damage to the bolt and to ensure a uniform surface finish, the holes with the therein arranged eccentric elements closed after connection of the post and bolt with flat elements. This is necessary because the eccentric elements must be accessible until the finished assembly.

In a comparable mullion-transom connection, instead of eccentric elements, nuts are arranged in comparable bores in the latch. Instead of connecting pins with heads, connecting pins used here have threads. For assembly, the nuts arranged in the bolt holes must be screwed onto the connecting pins. This is difficult because the nuts due to the arrangement in the bolt holes only by repeated application of a tool, such as a ring wrench, can be tightened.

In another known mullion-transom connection, the surface of a bolt provided for connection to a post is provided with a recess in which a first fastening plate made of metal is screwed. A second mounting plate made of metal is screwed to an associated surface of the post. To connect the post and the bolt, the bolt is pushed onto the post so that structures extending from one attachment plate engage in U-shaped receptacles of the other attachment plate. A bias between the post and the latch is produced by the fact that the structures extending from the one fastening plate engage each other when the bolt is slid on an inclined surface, thereby generating forces when the bolt is pushed, which presses the post and the bolt against one another. It is disadvantageous that this is laborious to attach the mounting plate of the bolt. Furthermore, the tolerances to be maintained in locating the mounting plates are tight to ensure that the desired preload is created when the latch is slid on. Furthermore, this post-and-bolt connection can only be used where the bolt can be pushed onto the post.

Another disadvantage of known mullion and transom connections, such as the above, is that the mounts and holes to be arranged in posts and holes for components of a compound must be made in each case depending on a to be interconnected mullion-transom pair. This is particularly necessary to take into account unavoidable manufacturing tolerances.

The publication DE 196 15 378 A1 relates to a sealing body for a connection between a post profile and a window or door frame profile, seen in the installed state, with a top on an end face of a chamber enclosing post profile contour and with a bottom sealingly against a frame profile, on its underside a sealing lip with having an outer edge and seen in the installed state to the extended to the frame profile imaginary chamber of the post profile revolves, and presses against the frame profile.

The publication EP 0 748 920 A1 relates to a corner or T-joint to frames or racks of closed or semi-open hollow sections with a connector insertable in at least one profile of the connection and provided with one or more connecting means which, when actuated in cooperation with the connector and the associated one or more connectors Profiles merge the profiles to be connected in a joint frictionally.

Object of the invention

The object of the present invention is to provide a mullion-and-transom connection which avoids the disadvantages of the prior art. In particular, the present invention is intended to provide a mullion-and-tie joint which has a small number of individual ones Includes components and can be produced in a simple manner, in particular without the use of special tools and complex assembly steps. Furthermore, the present invention is intended to provide a mullion-and-tie joint in which prefabricated posts and latches can be used.

Brief description of the invention

To achieve this object, the present invention provides a mullion and transom construction having the features of claim 1 and a method of manufacturing a mullion and transom construction of claim 8.

The inventive device for connecting a bolt and a post of a window or door frame or a framework of a facade has a connecting body for arrangement in a connecting body receiving in the bolt. The connecting body comprises a stop surface, which serves as a stop for a provided for cooperation with the bolt surface of the post, and a fixing pin, which is arranged in the connecting body in a fixed predetermined spatial relationship relative to the stop surface and serves to receive a fixing pin, the when connecting the bolt and the post for securing the connecting body in the bar is used.

The abutment surface and the Fixierstiftaufnahme may extend parallel to each other and the fixed spatial relationship can specify a fixed predetermined distance between the stop surface and Fixierstiftaufnahme.

The locator pin receptacle may extend obliquely with respect to the stop surface in the connector body, and the fixed spatial relationship may indicate, for example, a minimum and maximum distance between the locator pin receiver and the stop surface, an angle enclosed by the stop surface and the longitudinal axis of the locator pin receiver, and the like.

The connecting body may have a bore, preferably a threaded bore, which extends from the abutment surface in the connecting body. Preferably, the longitudinal axis of the bore is perpendicular to the stop surface.

For securing the connecting body to the post, a securing body is provided which extends away from the abutment surface of the connecting body. Preferably, the longitudinal axis of the securing body is perpendicular to the stop surface.

The connecting body and securing body may be integrally formed.

Preferably, the securing body at its free end on an external thread to screw the fuse body in the post can. Preferably, an external thread is used which allows screwing into the post without the use of additional components (eg threaded insert in the post).

Instead of an external thread of the fuse body may also have one or more structures at its free end, such. As snaps, hooks, and the like, to secure by engagement with a corresponding (eg, complementary) shaped receptacle in the post, the connecting body to the post non-positively and / or positively.

If the connecting body and the securing body are provided as a separate component, the securing body may have an external thread at its end opposite the free end in order to be screwed into the bore of the connecting body. It is not necessary that the bore of the connecting body has an internal thread.

In a preferred embodiment, the connecting body has at least one further fixing pin receptacle, which is arranged in a further fixed spatial relationship to the stop surface. The use of multiple pins is explained using the example of two pins. It is intended to use two perpendicular to each other arranged Fixierstiftaufnahmen. If the two Fixierstiftaufnahmen extend parallel to the stop surfaces, the fixed spatial relationships can define a common or two different distances between the stop surface and the Fixierstiftaufnahmen. If the first fixing pin receptacle and / or at least one further fixing pin receptacle extend obliquely in the connecting body with respect to the stop surface, the above statements apply mutatis mutandis with regard to the fixed spatial relationship.

Preferably, one or more Fixierstiftaufnahmen are used, which are formed as through holes in the connecting body.

The one or more locator pins may extend parallel to the stop surface in the connector body, or may include an angle with the stop surface.

The locator pin receptacle may have internal threads for using externally threaded locator pins to secure the connector body in the latch. It is also possible to use fixation pin receptacles without internal thread in conjunction with fixing pins with external thread, for example, if a suitable material pairing allows screwing a fixing pin in the Fixierstiftaufnahme.

As an alternative to using a fixing pin receptacle in the form of a bore or passage opening, it is provided that the fixing pin receptacle (s) is (are) provided in the form of a circumferential groove formed on the connecting body.

By the use of the fixing pin receptacle, which is arranged in the fixed predetermined relationship relative to the abutment surface, which in turn serves as a stop on the post, it is ensured that the fixing pin receptacle, when the connecting body is secured to the post, always in a desired, predefined spatial relationship relative to the post is arranged. For example, if the fixed spatial relationship defines a distance between the abutment surface and the Fixierstiftaufnahme, the Fixierstiftaufnahme this distance to the post, when the connecting body is attached to this.

This allows the bar to be prefabricated, at least with respect to the structures used to receive the connector body and secure the connector body with a locating pin in the latch, regardless of the post's manufacturing tolerances.

Preferably, the connecting body is formed in a cylindrical shape at least in the region which is to be arranged in the connecting body receptacle. This allows to use connection body receptacles in the form of holes. Alternatively, it is intended to use connecting body with triangular, square or polygonal cross-sections. Also in the case of connecting bodies formed in this way, connecting body receptacles in the form of bores can be used, wherein the connecting body can be secured in a form-fitting manner in this case, for example, by knocking, press-fitting, etc. in a connecting body receptacle.

Regardless of the shape of the connecting body, it is provided that the abutment surface is an end face of the connecting body that extends perpendicular to the longitudinal axis of the connecting body. Alternatively, it is possible for the abutment surface to be provided by a planar structure which extends away from the longitudinal axis of the connecting body and has a surface serving as a stop surface.

In a further preferred embodiment, the device comprises the locating pin to secure the connector body in the latch.

As a fixing pin, a smooth pin with a substantially constant cross section can be used. In order to be able to remove the fixing pin again, it is possible for the fixing pin to have a circumferential groove, an external thread, an internal thread or another form at its end situated in the assembled state with respect to the bolt in order to be able to engage it. By means of a pair of pliers, a provided with an internal thread sleeve, a screw, a threaded pin, etc., then the fixing pin can be removed again. The fixing pin may have an external thread at its end in the assembled state with respect to the bolt, in order to be screwed into the fixing pin receptacle of the connecting body. To achieve both functions, the fixation pin can be a fully threaded pin. In order to be able to screw in the fixing pin receptacle when using a fixing pin in the form of a threaded pin, it is advantageous if the fixing pin is formed at one end to cooperate with a provided for screwing the fixing pin tool. In this case, the locating pin may have, for example, a hexagon socket or structures for co-operating with a slotted or phillips screwdriver at one end. Regardless of the use of an externally threaded locator pin, the locator pin may have a longitudinally increasing cross section.

In order to facilitate arranging the connecting body to the post, the connecting body at its end opposite the abutment surface has a shape designed to cooperate with a tool to be used. For example, the connecting body may have a hexagon socket at this end. This end of the connecting body may additionally or alternatively have a surface on which, for example by means of embossing, a logo and / or logo can be attached.

The mullion and transom construction according to the invention, for example for window or door frames or a framework of a facade, comprises a latch with a connecting body receptacle formed therein for receiving the connecting device according to the invention and an opening for receiving a fixing pin and a post to be connected to the latch. The connecting body is attached to the post so that the abutment surface bears against it. The connecting body is further arranged in the connecting body receiving. The opening for receiving the fixing pin in the bolt is arranged as a function of the fixed spatial relationship.

For example, if the fixed spatial relationship indicates a distance between the Fixierstiftaufnahme and the abutment surface or the post, the opening of the bolt can be arranged by a cooperating with the post surface of the bolt at a fixed predetermined distance, as independent of manufacturing tolerances of the post, the fixing pin receptacle of the connecting body is always at the same distance from the post.

Preferably, the opening in the latch is located at a distance from the surface of the bolt intended to cooperate with the post, which is slightly larger than the distance of the fixing pin receptacle from this latch surface or the post. This ensures that the openings of the bolt and the Fixierstiftaufnahme partially overlap, so that a fixing pin can be introduced through the opening in the Fixierstiftaufnahme. Due to the offset between the opening in the bolt and the Fixierstiftaufnahme while forces are exerted on the connector body, which move it further into the bolt, so bias the posts and bars against each other. The larger the offset between the latch opening and the Fixierstiftaufnahme, the greater the biasing force.

When using a connecting body with a single Fixierstiftaufnahme only make sure that the Fixierstiftaufnahme is aligned so that a fixing pin can be introduced through the latch opening in the Fixierstiftaufnahme in the arrangement of the connecting body to the post. In the case of a single locating pin holder, the connecting body can be aligned for this purpose by a maximum of half a revolution with respect to its longitudinal axis when the locating pin holder extends completely through the connecting body. When using a Fixierstiftaufnahme that does not extend completely through the connecting body, a maximum of one complete rotation of the connecting body would be required. When using two Fixierstiftaufnahmen extending perpendicular to each other and completely through the connecting body, a maximum of a quarter turn of the connecting body will be necessary.

Such an orientation of the connecting body is eliminated when the fixing pin receptacle (s) is (are) formed as the connecting groove circumferential groove (s).

Regardless of whether alignment of the connector body with respect to the locator pin receptacle (s) is required, when using a threaded captive body, it is possible to vary the bias of posts and bars. For example, when assembling the mullion and transom construction to construct a window or door frame or stud, it is found that too little or too high a preload force due to manufacturing tolerances of the connector body and / or the latch is present, the connecting body can be further screwed into the post or unscrewed in the opposite direction. In either case, only a slight twist of the connector body will be sufficient to achieve the desired preload force.

In order to generate a biasing force between the post and the latch, it is provided that the fixing pin extends at least partially through the latch opening, on the one hand to attack this, and engages in or one of the Fixierstiftaufnahmen to support on the other hand at this. Preferably, the fixing pin extends completely through the fixing pin and supports, seen in the insertion direction, both before the Fixierstiftaufnahme and behind the Fixierstiftaufnahme in the latch opening.

The bolt opening may extend perpendicular to the longitudinal axis of the bolt and / or perpendicular to the longitudinal axis of the connecting body or include an angle with at least one of these longitudinal axes. The shape and / or arrangement of the latch opening depend inter alia on the type and shape of a provided fixing pin and / or the type and shape of the fixing pin receptacle to be used therewith.

Preferably, the latch opening is formed as a bore in the latch. In order to enable the fixing pin, as seen in the insertion direction, to be supported both in front of and behind the fixing pin receptacle in the bolt opening, the bolt opening preferably extends through the connecting body receptacle. In this case, the latch opening can extend completely through the latch. Preferably, however, the bolt opening does not extend completely through the bolt, but ends on the inside.

In order to impart an intact surface finish to the areas of the bolt visible in the assembled state, it is provided that the opening region of the bolt opening is arranged in a region of the bolt which is concealed by further components to be arranged on the post and / or bolt, such as e.g. , B. mounting and / or sealing profiles for windows or door panels in a window or door frame and facade elements in a facade framework.

For fixing the connecting body to the post, the post may have a bore, for example for receiving a thread of the securing body of the connecting body. When using a comparable formed to a wood screw fuse body can be dispensed with a formed in the post receptacle for the fuse body.

If, in addition to the connecting body according to the invention, further connecting elements, for example in the form of dowels, are provided, it is provided that receptacles provided in the post and / or the bolt (for example bores) have dimensions comparable to those in the post for the further connecting elements and / or bolt provided receptacles for securing the connecting body to the post or to the arrangement of the connecting body in the bolt. Thus, it is possible, for example, to make the holes provided in the post and / or bolt with respect to the connecting body and the holes provided for the further connecting elements with the same diameter.

Further, the present invention provides to use a device having the features of the above-described connecting device for connecting a bolt and a post for a mullion and transom construction (for example, for constructing a window or door frame or a framework of a facade).

The method according to the invention as defined in the claims and its embodiments are evident from the above description.

The present invention has several advantages. By using simple designed elements that can be standardized for any posts and bars, costs are reduced. Prefabricated bars and posts can be used, thereby avoiding processing steps in the actual assembly of bars and posts on site (eg on a construction site), in particular because post-assembly manufacturing tolerances are compensated. Posts and bars can be easily connected without special tools. In the assembled state, no components of the mullion-transom connection according to the invention are visible. Furthermore, it is possible to solve the post-and-bolt connection according to the invention in a simple way again.

Description of preferred embodiments

Fig. 1a - 1d show schematic representations of different views of a first preferred embodiment of the connecting body 2. The connecting body 2 comprises a running in this embodiment as a through hole Fixierstiftaufnahme 4. Optionally, the Fixierstiftaufnahme 4 have an internal thread 6. In order to facilitate the interaction of a provided for use with the connecting body 2 fixing pin (not shown here), the Fixierstiftaufnahme 4 with a chamfer 8 provided or lowered opening areas.

Starting from a surface 10 explained in more detail below, a bore 14 extends into the connecting body 2. The bore 14 has an internal thread 16. The surface 10 opposite surface 18 comprises an outer, formed as a chamfer area 20. The design of the surface 18 and the area 20 facilitates a described below arranging the connecting body 2 in a bar.

In the embodiment shown here, the surface 18 is substantially planar to, as in Fig. 1c and 1d represented, for example, by embossing a lettering (manufacturer's logo) to order.

In the Fig. 2 shown second preferred embodiment of the connecting body 2 differs, apart from their dimensions, characterized in that starting from the surface 18 a formed as a hexagon socket 22 extends into the connecting body 2. The hexagon socket 22 facilitates the attachment of the connecting body 2 described below to a post for a window or door frame or a framework of a facade. Instead of the hexagon socket 22, the surface 18 may be formed to cooperate with a flat-head screwdriver, Phillips screwdriver, open-end wrench, etc.

For attaching the connecting body 2 to a post threaded pins are provided, for example in Fig. 3 Grub screws 24 of different lengths are shown. For fastening the connecting body 2, a threaded pin 24 is screwed into a hole in a post. For this purpose, the in Fig. 3 shown grub screws 24 each provided a hexagon socket 26. Instead of a hexagon socket screws 24 can be used, which can be screwed for example by means of a screwdriver.

The length of the threaded pin 24 may be selected depending on the dimension of the respective post, which forces are to be received, and whether a grub screw 24, as described below with reference to Fig. 8 explained, to be used for fastening two connecting bodies.

On the screwed into a post threaded pin 24 of the connecting body 2 can be screwed using the internal thread 16 and secured to a post. In this case, the surface 10 comes to the post to the plant, which is why the surface 10 is also referred to as a stop surface.

Fig. 4 illustrates a third preferred embodiment of the connecting body 2. Comparable to the connecting body 2 of Fig. 2 In this embodiment, the connecting body 2 has a fixing pin receptacle 4 designed as a through-hole and a hexagon socket 22. In contrast to the above embodiments, the connecting body 2 here at the opposite end of the surface 18 has a threaded body 28 with an external thread 30 disposed thereon.

The threaded body 28 and the external thread 30 serve, similar to the threaded pin 24, for securing the connecting body 2 in a bore of a post. The remaining part of the connector body 2, which may be referred to as a connector main body 32, is for arrangement in a connector body receiver of a latch. At the end of the connection main body 32 adjacent to the threaded body 28, a structure 34 extending away from the connection main body 32 substantially perpendicular to the longitudinal axis of the connection body 2 is provided. The structure 34 may be made completely integral with the connection main body 32 or may comprise individual elements, teeth or protrusions. The number and / or shapes of such elements can be chosen arbitrarily, as long as the function of the structure 34 is ensured. The pointing to the threaded body 28 surface 10 of the structure 34 is, comparable to the abutment surface 10 of Fig. 1 and 2 as a stop on a post when the connecting body 2 is attached thereto. The function of the structure 34 is essentially to ensure that the connector body 2 can only be screwed into a post so far until the abutment surface 10 rests against the post.

In view of this function of the structure 34, it is not necessary for the structure 34 to be made particularly stable. Accordingly, it is possible to make the structure 34 small in the longitudinal direction of the connecting body 2. For example, it is possible to make the structure 34 having a thickness (dimension in the longitudinal direction of the connecting body 2) of less than 1 mm, preferably less than 0.5 mm or even smaller.

The connecting body 2 is embodied here in one piece and has the structure 34 integral integrated. For example, the connecting body 2 can be produced by machining a correspondingly dimensioned blank. A blank may be used in the form of a threaded pin, in which the thread is removed (eg turned off) in the area provided as the connecting main body. In this case, this region of the blank can be processed so that immediately adjacent to the area provided as a threaded body 28 forms an accumulation of material, a burr remains or the like, in any case a shape is obtained, which then serves as a structure 34.

It is also possible to produce the connecting body 2 using a blank in the form of a smooth pin, wherein this blank is machined so that on the one hand the threaded body 28 with the thread 30, on the other hand, the connecting main body 32 and intervening structure 34 is formed.

In Fig. 5 are shown for use with the connecting body 2 provided fixing pins 36 of different lengths. The fixing pins 36 are dimensioned so that they can be introduced into the Fixierstiftaufnahme 4. In the Fig. 5 Fixing pins 36 shown each have a conical end 38, which facilitate the introduction of a fixing pin 36 in cooperation with the chamfer 8 of the Fixierstiftaufnahme 4.

Furthermore, the fixing pins 36 have an external thread 40. The use of external threads 40 makes it possible to screw a fixing pin 36 into a fixing pin holder 4.

As stated above, it is also provided that the Fixierstiftaufnahme 4 does not include an internal thread 6. Also, the use of the external thread 40 is advantageous if the material of the connecting body 2 and / or the material of the fixing pin 36 is selected so that the external thread 40 at the introduction of the fixing pin 36 in the Fixierstiftaufnahme 4 whose inside at least partially threaded ( in this case, the insertion of the fixing pin 36 into the fixing pin holder 4 can be compared with the use of a tap).

At their end 42 opposite the conically shaped end 38, the fixing pins 36 have a hexagon socket 44 or, as not shown, are shaped so that the threaded pins 36 are inserted or screwed into a corresponding fixing pin receptacle 4 by means of a screwdriver, pliers etc. can. The use of such shaped ends 42 also makes it possible to easily remove the threaded pins 36 again.

Fig. 5 shows fixing pins 36 of different lengths, which, as with reference to Fig. 10 explained in more detail, are selected so that only a small number of differently long fixing pins 36 is required for a variety of different sized bars.

Referring to Fig. 6 The connection of a post 46 and a bolt 48 will now be described, for example, serve as a pillar and bolt of a window or door frame or a framework of a facade. It is assumed that the post 46 and the latch 48 are made of wood; however, posts and bars are also off other materials provided, such. As metal and plastic and combinations of different materials, such. As metal and wood, metal and plastic, plastic and wood and wood, metal and plastic.

In the post 46 is a bore 50 for receiving a threaded pin 24 (see Fig. 3 ) or the threaded body 28 (see Fig. 4 ) produced. The bore 50 may also have an internal thread 52 or the like.

In the latch 48, a connecting body receptacle 54 is produced. The connecting body receptacle 54 is dimensioned such that it surrounds the connecting body 2 Fig. 1 2 and the connection main body 32 of Fig. 4 can completely absorb. In particular, the length or depth at which the connecting body receptacle 54 extends into the latch 48 corresponds at least to the length of the connecting body 2 between the abutment surface 10 and the opposing surface 18 or the length of the connecting main body 32.

In the latch 48, a bore 56 is further prepared. In the embodiment shown here, the bore 56 extends substantially perpendicular to the longitudinal axis of the bolt 48. The bore 56 serves to receive a fixing pin 36 and, unlike the illustration, can extend completely through the bolt 48. Advantageously, the bore 56 does not extend completely through the latch 48, but ends, starting from a provided as a bolt outside surface 58 in the latch 48, d. H. in front of a provided as a bar space side surface 60. As a result, a uniform surface finish of the bolt 48 is achieved on the room side.

The bore 56 is arranged at a distance 62 from a surface 64 of the bolt 48, starting from which the connecting body receptacle 54 extends into the latch 48. The distance 62 is selected so that a fixing pin 36 can be introduced into the bore 56 and the fixing pin receptacle 4 when, as described below, the connecting body 2 is fastened to the post 46 and received in the connecting body receptacle 54. It is possible that the distance 62 is so large that the bore 56 and the Fixierstiftaufnahme 4 are completely aligned with each other when the connecting body 2 is arranged.

Advantageously, however, a slightly greater distance 62 is used, so that the bore 56 with respect to the Fixierstiftaufnahme 4 in the direction of the surface 64 away (ie in Fig. 6a to the right) or only partially aligned with the Fixierstiftaufnahme 4 is arranged. In this case, the bore 56 is provided so that a fixing pin 36 continues in the Fixierstiftaufnahme 4 can be introduced. By this arrangement of the bore 56 is achieved that when introducing a fixing pin 36 in the bore 56 and the Fixierstiftaufnahme 4 forces are exerted on the connector body 2, the latter further into the Verbindungskörperaufnahme 54 (ie in Fig. 6a move to the right).

Determining which spacing 62 to use will allow the bore 56 in the latch 48 to be made without the need to know the actual dimensions of the post 46 and to locate the connector body 2 in the connector body receptacle 54. Consequently, can be provided prefabricated so to be connected with a post bars, so that a processing of bars, in particular with regard to openings or holes for receiving pins during assembly, for example, on a construction site, eliminated.

For connecting the post 46 and the latch 48, as in Fig. 6b shown, the connecting body 2 so far screwed into the bore 50 until the stop surface 10 contacts a surface 66 of the post 46. In this position of the connecting body 2, the Fixierstiftaufnahme 4 regardless of the dimensions of the post 46, in particular independent of manufacturing tolerances, due to the voltage applied to the surface 66 stop 10 by the connecting body 2 predetermined distance 62 from the surface 66th

When fastening the connecting body 2 to the post 46, only the connecting body 2 is to be aligned by appropriate rotation so that the fixing pin receptacle 4 extends in the direction shown in this figure. If, as stated above, the connecting body 2 identifies two or three Fixierstiftaufnahmen, this orientation can be simplified.

After that, as in Fig. 6c 1, the latch 48 is pushed or pressed onto the connection body 2, so that the surface 64 of the latch 48 contacts the surface 66 of the post 46 and the connection body 2 is received in the connection body receptacle 54.

To secure the post 46 and the bolt 48 to each other, a fixing pin 36 is inserted into the bore 56 and the fixing pin 4. Depending on the design of the fixing pin 36 used, this can be done by wrapping, screwing and the like. Is, as stated above, the distance 62 chosen so that the bore 56 is arranged offset relative to the Fixierstiftaufnahme 4, while forces on the connecting body 2 exercised to move this further into the latch 48 and thereby increase a force acting between the surfaces 64 and 66 contact force.

In order to additionally increase the contact pressure acting between the surfaces 64 and 66, the connecting body 2 can be further screwed firmly to the post 46 by, for example, a half or a full turn. This possibility exists in particular for posts made of wood, which allow a slight penetration of the stop surface 10 in the surface 66. If, as stated at the outset, the connecting body 2 identifies two or three fixing pin receptacles, this can be achieved by smaller rotations of the connecting body 2 (eg 1/3 or 1/4 revolution).

Fig. 7 shows views of comparable with the end face 64 of the bolt 48 end faces 64 of bars 48 of different width. In order to achieve the most uniform possible contact pressure between the end faces 64 and the surfaces 66 of posts, not shown here, the connecting body receptacles 54 are arranged centrally with respect to the width of the latch 48. Furthermore, in Fig. 7 Holes 68 shown, which are provided for receiving dowels, such as wooden dowels. In the assembled state dowels are arranged in the holes 68 and corresponding holes of posts, on the one hand improve the connection of bars and posts and on the other hand serve for vertical and horizontal load transfer.

In the Fig. 7 shown connecting body receptacles 54 are for use with Verbindungskörpem 2 of Fig. 1 and 2 intended. When using the connecting body 2 of Fig. 4 can be used as a connecting body receiving holes that have the same diameter as the holes 68. This has the advantage that the same tools can be used both for producing connecting body receptacles and for producing bores for receiving dowels. Another advantage arises when in this case connecting body receptacles and holes for receiving anchors are also comparable in terms of their drilling depth.

Fig. 8a and 8b show views of a post 46 and latch 48 in assembled condition for constructing a planar post-and-beam construction. In a post-and-pillar construction, posts and ties generally define a plane that forms a flat, non-curved window or door front or facade front. In this arrangement, referred to as T-connection, the connecting body 2 of Fig. 2 arranged in the connecting body receptacle 54. Further, a fixing pin 36 is used, which extends completely through the fixing pin 4. This ensures that the fixing pin 36 seen in the direction of the bore 56 both before and behind the Fixierstiftaufnahme 4 in the bore 56 is arranged and can absorb forces there. The fact that the bore 56 is arranged on the outside, the bore 56 and thus the fixing pin 36 are not visible from the room side. On the outside, the bore 56 and the fixing pin 36 are concealed by components to be arranged on the post 46 and / or the latch 48 (eg elements for fixing window panes, door panels and facade elements).

In Fig. 9a and 9b a cross connection of a post 46 with two bars 48 is also shown for a planar post-and-beam construction. The preparation of such a connection substantially corresponds to the above-described connection of a post and a bolt. In the embodiment shown here, the connection of two connecting bodies 2 of Fig. 2 a grub screw 24 is used, which extends completely through the post 46 and serves to secure both connecting body 2. Alternatively, it is possible to use in each case a threaded pin 24 for the connecting body 2 instead of a common threaded pin 24. In this case, the post 46 with two bore 50 of Fig. 6a comparable single holes or a through hole are provided. Here, too, the bores 56 provided for receiving fixing pins 36 are arranged on the outside, whereby the bores 56 and the fixing pins 36 are not visible from the room side and are concealed on the outside by components to be attached to the post 46 and / or the bars 48.

As with reference to Fig. 5 explained, it is intended not to use a correspondingly sized fixing pin for each bolt depth. Rather, fixation pins should be used in lengths that are each suitable for multiple Riegeliefen. Fig. 10 shows a graphical representation, can be determined from the different locking depths, which Fixierstiftlänge is suitable. It is assumed that the drilling depth of a hole in a bolt for receiving a fixing pin (see Fig. 6a For example, bore 56) is 15mm smaller than the groove depth. Furthermore, it is assumed that a connecting body receptacle 54 is arranged centrally with respect to the depth of the latch and a fixing pin extends completely through a fixing pin receptacle 4 and, for example, by 10 mm.

As Fig. 10 For locking depths between approximately 70 mm and 95 mm, fixing pins with a length of 65 mm, for lock depths between 95 mm and 115 mm, fixing pins with a length of 80 mm, for lock depths between 115 mm and 155 mm, fixing pins with a length of 100 mm, for bolt depths from 155 mm to 235 mm, fixing pins with a length of 140 mm and for bolt depths between 235 mm and 355 mm, fixing pins with a length of 200 mm are used.

For the embodiments described below applies, unless otherwise stated, the above embodiment accordingly.

Fig. 11 and 12 show schematic cross-sectional views of a mullion-transom construction according to Fig. 8a and 8b a window or a façade in the region of fastenings of window panes or facade elements 68. According to the invention, a latch 48 is connected to a post 46 by means of a connecting body 2 and a fixing pin 36. On an outer side 58 of the bolt 48, a base profile 70 is attached. The base profile 70 has a receptacle 72 extending from the latch 48, which serves to fasten a retaining profile (see below) to the base profile 70 by means of a screw. The receptacle 72 comprises on its outer side structures which interact positively with an insulating profile 74.

On an explanation of the other in Fig. 11 shown components, namely seals 76, glass supports 78, seals 80, retaining profile 82, screw 84 and cover profile 86, can be omitted here.

As stated above, the connection according to the invention makes it possible to use prefabricated bars at least in this respect (ie bars with prefabricated connecting body receptacles 54 and bores 56). Furthermore, when using the gate and bolt connection according to the invention, it is possible to provide the latch 48 so prefabricated that the base profile 70 and optionally glazing gaskets 76 and / or the insulating profile 74 are attached thereto. Namely, the fixing pin 36 can, as in Fig. 12 recognizable, are introduced by the pre-mounted on the latch 48 elements in a bore 56 and fixing pin 4. This can be achieved by pre-assembled elements provided with correspondingly sized and dimensioned openings and / or by providing pre-assembled elements with corresponding openings in the assembly of posts and latches. This also allows the connection of post 46 and latch 48 to be adjusted (by) by means of locating pin 36 by further or less inserting locating pin 36 into bore 56. Removal of the fixing pin 36 is also possible despite elements attached to the latch 48 (eg base profile 70, insulating profile 74). Regardless of the extent to which the latch 48 is prefabricated, the opening 56 and the fixing pin 36 are concealed in the assembled state.

Advantageously, the fixing pin 36 protrudes, as in Fig. 12 shown, not from the latch 48 out, but closes flush with the latch 48 or ends within the bolt 48 and the bore 56. This prevents the fixing pin 36 acts as a cold or thermal bridge and deteriorates the insulation properties. Are the post 46 and the latch 48 connected in the desired manner, for example by adjustment of the fixing pin 36, in the region of the base profile 70 and the damping profile 74 existing spaces, which serve for example for introducing the fixing pin 36 into the bore 56, with sealing material (eg silicone) are filled in order to further improve the insulating properties.

Fig. 13 shows a view of a post 46 and a bolt 48 in the assembled state to build a curved mullion-and-transom construction. In a curved mullion and transom construction, uprights and lobes form a single or multiple curved surface (eg, by using curved latches) to form a single or multiple curved window or door front or façade front. In contrast to the above embodiments, in this embodiment, an opening 56 is formed from the top of the bolt 48 (ie, substantially perpendicular to the direction of the bore 56 of FIG 8 and 9 ). The bore 56 may also be provided starting from the underside of the bolt 48. Otherwise, the explanations given above apply here accordingly.

In Fig. 14 For example, a cross connection of a post 46 with two latches 48 is also shown for a curved mullion and transom construction. Comparable to the embodiment of Fig. 13 , Holes 56 are also formed here starting from the tops of the latch 48 in this. Incidentally, the above explanations also apply to this embodiment.

In the embodiments according to FIGS. 13 and 14 used holes 56 allow it, comparable to those in Fig. 5 and 10 Selected Fixierstiftlängen to define a set of pins of different lengths regardless of the dimensions of the latch 48, which provide a curvature of the mullion-and-transom construction. By extending from the tops of the latch 48 holes 56, the lengths of fixing pins are substantially of bolt widths (ie dimensions of the latch 48 perpendicular to the drawing levels of FIGS. 13 and 14 ) certainly. Another advantage of this embodiment of the bores 56 is that the connections of the posts 46 and the latch 48 can still be adjusted even if 48 further elements are arranged on the bars. The openings 56 and thus the fixing pins 36 remain accessible even then. In order to give the bars 48 a uniform surface finish desired primarily for aesthetic reasons and to prevent penetration of particles and moisture, covers to be arranged in the opening areas of the bores 56 can be used. Such covers can be glued or secured to the fixing pins, if they have, for example, a hexagon socket.

Fig. 15 shows a schematic cross-sectional view of a mullion-transom construction according to Fig. 13 of a window or a façade in the region of fastenings of window panes or façade elements 68. The reference numerals used in this figure denote elements which correspond to the elements shown in FIG Fig. 11 and 12 shown elements with the same reference numerals are comparable. In a latch 48, a connecting body 2 is arranged and secured by a fixing pin 36 which extends through a bore 56 in the latch 48 and a fixing pin 4 formed in the connecting body 2. To the opening area of the bore 56 flush with the in Fig. 15 to close the right-facing surface of the bolt 48, the fixing pin 36 ends within the bolt 48. Otherwise, the statements made above apply accordingly.

FIGS. 16 and 17 show, comparable to FIGS. 13 and 14 Connections of posts 46 and latches 48 for a curved mullion and transom construction. Unlike the embodiments of FIGS. 13 and 14 are in the embodiments of FIGS. 16 and 17 , comparable to the embodiments of 8 and 9 , Holes 56 are arranged starting from outer sides of the latch 48 in this. As explained above, this arrangement of the bores 56 has the advantage that the bore 56 and fixing pins 36 for securing connecting bodies 2 in the bars 48 are covered by elements which are attached to the bars 48, for example for fixing glass panes or façade elements , The length of fixing pins to be used in such a construction is determined by the respective depth of the bolt in the area of a bore 56. Again, it is possible to define a set of fixation pins of different lengths.
