Abstract

The connector (1) has a base part (2) fastened with a frame strip and a mounting part (3). The mounting part and the base part include shaping at sides such that the parts are positively guided for connecting in a direction perpendicular to a longitudinal axis of the strip in an interconnected manner. The parts are moved upward to an end position, and are fastened together by a connecting device e.g. screw or screw bolt, in the end position. The device is guided through a region parallel to the longitudinal axis, where the region is formed by the interconnected parts.

Description

The invention relates to a post connector comprising a base part attachable to a frame strip and a insertable into a hollow cross-section of a post and there attachable Aufsteckteil, wherein Aufsteckteil and base are superimposed one above the other fastened to each other.

Such post connectors serve the mechanical connection of frame profiles of windows, doors or the like. With post or rungs profiles.

Such a multipart post connector is z. B. from the EP 1 035 294 A2 known. This post connector comprises a foot part to be fastened to the upper side of a frame strip, to which a shaft part can be placed, which has on its upper side a molding section which can be inserted into a hollow cross-section of a post and fastened there. The foot part and the shaft part are fastened in superimposed arrangement to each other by means of a clamping screw, which is passed from the inside of the cavity of the frame profile forth through the foot part and screwed into the shaft part. For this purpose, aligned holes are provided on the frame profile and a seated in its hollow cross-section reinforcing profile, which not only allow the insertion of the clamping screw itself, but also the insertion of a screwdriver or a hexagon socket wrench for tightening the screw. In this case, the foot part and shaft part can be mounted substantially perpendicular to each other during assembly on their sides facing each other, because the foot mounted Justierzapfen lying in annular recesses, in engagement with on the facing surface of the foot correspondingly arranged Justierbohrungen, but of annular Elevations are surrounded, must be brought. Because thus a lateral sliding of the shaft part on the foot part but no longer possible, must be in the only of the inside of the previously completed window or door frame vornehmbaren mounting of the post as a result of these increases the assembly significantly complicating deformation of the parts during installation of the post in To be taken. Also, the attachment of the foot part and shaft part together over on the outside of the frame profile to be mounted, aligned with the bore of the clamping screws bores and the introduction of the clamping screws and tightening the same through these holes also represents a complicated assembly step.

Another post connector of the type mentioned is in the DE 197 45 750 C2 described. Again, projections on the foot part facing the underside of the shaft part are mounted, which engage in the assembled state in corresponding recesses on the upper side of the foot part. Although the height of the projections is small, if you want to perform a lateral sliding of the shaft portion on the foot part during assembly, still a certain deformation of the parts during insertion of the post required, which complicates the assembly. Finally, even with this known post connector, when the foot part and the shaft part are arranged one above the other, the connection between the two is made by using a fastening anchor, which is braced from the outside of the frame, in a similar manner as in the known post connector discussed above.

Similarly, in the two-part structure of the from DE 4444274 C2 known post connector with a base part and a Aufsteckteil mountable thereon in turn provided the connection between the two by means of a clamping screw which is screwed from the frame through a hole in the base part into a threaded nut which is mounted in Aufsteckteil and thereby, again from the frame side , the two parts (and attach the posts on posts) braced against the frame strip.

Proceeding from this, the present invention seeks to improve a two-part mullion connector of the type mentioned so that the assembly of the two parts can be done on the frame by a problem-free lateral pushing the Aufsetzteiles on the base part and the connection between the two parts particularly quickly and easily can be made and no longer must be done from the frame outside.

According to the invention this object is achieved in a mullion connector of the type mentioned in that Aufsetzteil and base part on their sides facing formations such that they mating in the direction perpendicular to the longitudinal axis of the frame strip positively interlocking out and slidable to the final assembly position and in this can be fastened to one another by means of a connection means guided parallel to the longitudinal axis of the frame side through the region of the positive engagement.

The post connector according to the invention provides for the assembly of the base part and Aufsetzteil targeted formations on their facing sides, which form perpendicular to the longitudinal axis of the frame strip, so in fertiggestellem frame: perpendicular from the inside of the frame forth, a form-fitting interlocking guide between the two parts, in the two parts are displaceable up to their final assembly position, without any difficulties in the lateral insertion would be present as a result of protrusions occurring perpendicular to the direction of displacement. And quite differently than hitherto known, the attachment of base member and Aufsetzteil together after they are brought into their mounting end position, by means of a compound which acts parallel to the longitudinal axis of the frame strip through the region of the form-fitting intermeshing guide portions of both parts and thus the two parts against each other braced and thereby fastened to each other.

In the post connector according to the invention, the desired function of a sliding from the inside of the frame during assembly of the two parts successively by means of a positive guide in combination with a through the form-fitting interlocking and leading portions of both parts, parallel to the longitudinal direction of Frame strip (and thus perpendicular to the direction of displacement of the Aufsteckteiles relative to the base part) effective fastening means a particularly easy and quick installation of the post connector and the parts connected to it frame bar and posts achieved. It requires for the mounting of the two parts of the post connector to each other no longer the attachment of special access holes, by means of which from the outside of the frame profile clamping screws in the latter must be introduced and tightened. Rather, given the possibility according to the invention post connector, fasteners such. B. clamping screws, splice bolts o. Ä. To use, which are parallel to the longitudinal axis of the frame strip and therefore easily during assembly each side of the post (and no longer from the outside of the frame forth) for bracing attachment of the two connector parts can be clamped together.

This particular arrangement and orientation of the fastener for the two parts of the post connector is just by the perpendicular to the longitudinal axis of the frame profile guide by means of a positive engagement of correspondingly interlocking sections of both parts of the post connector possible, so that this combination of positive engagement and perpendicular through the form-locking interlocking parts through effective fastening give the special advantages of the invention.

That the laterally positively guided pushing the Aufsteckteiles on the base part allows a particularly rapid installation, is obvious. The attachment of the two parts of the post connector to each other by a succession of the post screwing suitable clamping elements, which are effective through the form-fitting interlocking sections of both parts, is also easy and quick to carry out, so that overall results in a particularly fast assembly of the post connector according to the invention ,

The post connector according to the invention, once it is mounted, can be dismantled without difficulty again, with built-in frame, without having to be exposed from the outside of the frame access.

In the post connector according to the invention, in principle, any connection means can be used which, across the form-fitting intermeshing guide sections of attachment part and base part, allows them to be braced against each other and thus to secure the parts together. Preferably, however, because particularly simple and easy to install, the connecting means consists of one or two screw (s) or from a bolt passing through the region of the mutual positive connection of mounting part and base part and by means of which they are mutually braced.

For the positive guidance when moving the Aufsetzteiles on the base member any suitable shaping can be used, which also allows the passage of a connecting means through the region of the form-fitting interlocking portion of both parts. However, a particularly preferred embodiment of the form-fitting guide is achieved in that the mounting part is guided on the base part by means of a dovetail guide slidably and perpendicular to the longitudinal axis of the frame strip.

Another equally advantageous embodiment of the form-fitting guide is in the post connector according to the invention also in that the mounting part forms on its side facing the base part a flat surface, directed from the perpendicular to her and also to the longitudinal axis of the frame strip, at least one plate-shaped part protrudes, which engages in a corresponding in the facing side of the base body of the base part formed mold groove, along which it is positively received until it reaches the final assembly position between the base part and Aufsteckteil perpendicular to the longitudinal axis of the frame strip.

This as well as the leadership by a dovetail groove form inexpensive producible and form-fitting excellently effective guides.

In a further advantageous embodiment of the post connector according to the invention, a stopper is provided on the base part, against which the mounting part comes when it moves relative to the base part when the mounting end position is reached, with a contact surface formed on the stop surface for conditioning. As a result, the assembly is particularly simplified by lateral insertion, since the stop makes it unnecessary to monitor the displacement path when reaching the final assembly position.

The base part of the post connector according to the invention, which is first attached to the frame strip, is preferably carried out by its attachable part facing side by means of at least one screw, in particular a countersunk screw o. Ä., Attachable to the frame strip. Thus, the assembly of the base part of the frame strip can be made automatically at a time, even before the relevant frame part is welded, which proves to be particularly advantageous.

The attachment of the Aufsetzteiles on posts done in a post connector according to the invention, preferably by means of a screw, wherein any other suitable connection could be used here.

A further advantageous embodiment of the invention is also the fact that in a post connector according to the invention, the stop on the base part, against which the stop surface on the mounting part on reaching the mounting end position comes to a stop during insertion, from a projecting perpendicularly from the base part, over the longitudinal direction of the Frame bar is extending length of the base part extending web.

It is particularly favorable in a post connector according to the invention also when the base part has on its side facing the frame strip profiling of the frame strip complementary profiling, which can be a frame strip corresponding counter profiling of the post avoided and thus the post on its the post connector facing underside can be cut off by a plane cut.

The figures show an embodiment of a post connector 1 according to the invention, wherein the same reference numerals are assigned to the same part in all figures.

The post connector off Fig. 1 consists of two parts, namely a base part 2, which in Fig. 2 enlarged perspective view is shown, and a Aufsetzteil 3, in a perspective, also enlarged view the 3 and 4 demonstrate.

The base part 2, as out Fig. 5 can be seen on a frame strip 4 (from the Fig. 5 only one section shows) above, that is mounted on its side facing the enclosed frame surface, while the attachment part 3, such as Fig. 5 also shows at a post 5 (of the Fig. 5 also shows only a portion) at the bottom of this, that is attached to the frame strip 4 facing end surface. The attachment part 3 is, as in Fig. 3 shown, with an upper mold portion 7, which protrudes away from a flat, upper support surface 8 on Aufsetzteil 3 in the direction of the base part 2 of the post connector 1, inserted into the hollow cross section 6 of the post 5 so far form-fitting until the upper support surface 8 of the Aufsetzteiles. 3 comes to rest against the lower end surface 9 of the post 5, which faces the frame rail. This condition is off Fig. 5 removable.

As the Fig. 1 shows, for the formation of the post connector 1, the two parts thereof, namely the base part 2 and the attachment part 3, assembled so that they are arranged one above the other.

• Das Basisteil 2 besteht, wie Fig. 2 zeigt, aus einem im wesentlichen plattenförmigen Grundkörper 10, der oben auf der Rahmenleiste 4 in einer Profilnut zwischen einem der Außenseite des Fensters, der Türe o. ä. zugewandten Außenflansch 13 an der einen Längsseite der Rahmenleiste 4 und einer Nut 15 am gegenüberliegenden Seitenrand der Rahmenleiste 4 angeordnet wird.

First of all, the design of base part 2 and attachment part 3 are described in more detail:

• The base part 2 is how Fig. 2 shows, from a substantially plate-shaped base body 10, the top of the frame strip 4 in a profile between one of the outside of the window, the door o. Ä. facing outer flange 13 on one longitudinal side of the frame strip 4 and a groove 15 on the opposite side edge of Frame strip 4 is arranged.

The base body 10 extends substantially perpendicular to the longitudinal direction L - L of the frame strip 4 and has a substantially rectangular shape in plan view (see. Fig. 2 ).

In the main body 10, two mutually parallel and perpendicular to the longitudinal axis L - L extending guide grooves 16 are inserted, each having a depth t and almost over the entire course of the body 10 in the transverse direction perpendicular to the longitudinal axis L - L of the frame strip 4 extend.

Between the two guide grooves 16 are two holes 17 for countersunk screws 31 (in the illustrated embodiment) Fig. 5 ), whose centers are also on a parallel to the two guide grooves 16 extending straight line.

The base body 10 is provided at its outer flange 13 facing the end with a perpendicular to its surface 18 and the guide grooves 16 directed vertically upwardly extending web 11, which merges at its upper end in a running perpendicular to him support plate 12. The support plate 12 extends from the web 11 so as to completely cover the top of the outer flange 13 of the frame strip 4 and is supported on this, as this Fig. 5 shows.

The support plate 12 extends in the illustrated embodiment in the longitudinal direction L - L of the frame strip 4, on both sides of the web 11 like a wing above, a total of a length l (see. Fig. 2 ), which corresponds to the width b of the assembled state on its outer flange 19 of the post. Thus: l = b .

Reference is now made to the Aufsetzteil 3, which in the 3 and 4 is shown, where Fig. 3 a top perspective view of the top and Fig. 4 the part out Fig. 3 but on its underside, illustrated.

In this case, the attachment part 3 consists of a central block part 20, which on its upper, d. H. the post 5 facing side forms an upper planar support surface 8, from the upwardly projecting a mold section 7 for insertion into the hollow cross section 6 of a post 5. This upper mold portion 7 is formed with respect to the hollow cross section 6 of the post 5 so that it can be positively inserted into the latter until the end face 9 of the post 5 comes against the upper support surface 8 of the Aufsetzteiles 3 to stop.

The central block part 20 of the Aufsetzteiles 3 has a shape and size that substantially corresponds to the shape and size of the base body 10 of the base part 2 lying in the assembled state below it.

The central block portion 20 is provided on its underside with a lower planar support surface 21, projecting from the two plate-shaped strips 22 perpendicular. The arrangement of these strips 22, their projection and their width are chosen so that they engage in the assembled state of the base part 2 and 3 Aufsetzteil in the two guide grooves 16 and fill them almost completely in the final assembly state. It is possible, the mounting part 3 to supply the base body 10, that the strips 22 of the support plate 12 of the base part 2 opposite side of the base body 10 (ie from the frame inside) can be inserted into the opening there 16 guide grooves. Thus, a guided application of the Aufsetzteiles 3 perpendicular to the longitudinal axis L - L of the frame strip 4 is ensured on the base part 2, wherein the underside 21 of the Aufsetzteiles 3 rests on the surface 18 of the base body 10.

Of course, other embodiments for forming the positive guidance of the Aufsetzteiles on the base part 2 are possible. So z. B. instead of the two strips 22 of the Aufsetzteiles 3 and the guide grooves 16 may be formed on the base part 2 at this also a dovetail groove, into which a mounted on the attachment part 3, the groove cross section corresponding guide part with dovetailed cross-section inserted and slidably received, said in this If the holes 17 for fixing screws on both sides of the dovetail groove are attached.

When Aufsetzteil closes, like the 3 and 4 show what is referred to, on its in the assembled state of the support plate 12 opposite side of a flange 23, which extends from the upper support surface 8 downwards and on both sides, perpendicular to the latter, protrudes beyond the support surface 21, to the extent that how the cross-sectional view of Fig. 9 shows, the end face 25 of the flange portion 23 rests on the upper side of the lateral boundary walls of the groove 15.

Laterally, the flange portion 23 extends in two from the central block member 20 each laterally projecting retaining grooves 26, the shape of which, as from Fig. 5 and 6 is directly removed, exactly the shape of a corresponding retaining groove 26 'corresponds to the post 5. The retaining grooves 26 and 26 'are aligned with each other, whereby it is possible to form a retaining groove of this shape on both sides of the block member 20 over the entire height of the post 5 on the inside thereof.

This holding grooves 26, 26 'serve to receive a glass retaining strip, fitting parts o. Ä. The post 5 can on its underside, at which the Aufsetzteil 3 is inserted into the hollow section 6, with a flat section to form a flat lower end surface. 9 be cut off and not, as previously required, the shape on the associated top of the frame strip 4 are accordingly counter profiled.

On Aufsetzteil 3 are also such. B. the 3 and 4 show good, laterally outside the two mutually parallel guide rails 22 in the central block portion 20 through this passing holes 27 mounted, through which the inserted into the hollow cross section 6 of the post 5 upper mold section 7 of the Aufsetzteiles 3 by means of corresponding, passed through the openings 27 screws 31 on Post 5 can be attached (not shown in the figures).

When the base part 2 and the attachment part 3 of the post connector 1 are placed on each other and in their in Fig. 1 shown mounting end position are spent, the attachment part 3 is so far shifted relative to the base part 2, that the web 11 facing the front end surface 29 of its central block member 20 against its facing surface of the web 11 comes into abutment against the Einschiebebewegung the Aufsetzteiles 3 forms a stop.

On the base part 2 as well as on the mounting part 3 holes 28 are also mounted so that in the collapsed state according to Fig. 1 an aligned through the base body 10 and the strips 22 through-hole 28 is formed, as is apparent from the sectional view of Fig. 7 is clearly recognizable. This through hole 28 thus passes both through the base body 10, as well as through the strips 22 therethrough. This makes it possible, by means of a suitable introduced into the flow hole 28 fastener, such as by means of a correspondingly long screw or two screws 30 (FIGS. Fig. 7 ) or by means of other hindurchsteckbarer components (such as splice bolts or the like) to provide a firm connection between the base part 2 and 3 Aufsetzteil, which also blocks the relative position of both.

In Fig. 7 the corresponding design for two screws 30 is only shown in principle, wherein the cutting position of the cut according to VII - VII Fig. 6 equivalent.

For mounting such a post connector 1 is first, as in Fig. 5 shown, a base part 2 mounted on the top of a frame strip 4 at a corresponding desired location and fixed there by means of countersunk screws 31 on the frame strip 4, wherein the countersunk screws 31 are passed through the holes 17 from above and screwed into the bottom frame 4.

In addition, the attachment part 3 is inserted with its upper mold section 7 to the stop of its upper support surface 8 against the lower end surface 9 of the post 5 in the hollow section 6 and there in a suitable manner, for. B. by means of screwed through the holes 27 screws, attached to the post 5 (not shown in the figures).

This is the in Fig. 5 illustrated starting situation.

Now, the post 5 is inserted with the attachment part 3 attached to it from the inside of the later frame forth with its two parallel lower strips 22 in the guide grooves 16 in the base 10 of the base part 2 and there, with simultaneous support of the support surface 21 of the central block part 20 on the facing surface 18 on the base body 10 of the base thistle 2, so long in the direction of the web 11 is shifted toward, until the front end surface 29 of the central block portion 20 abuts against the facing surface of the web 11.

By this form-fitting fixed and also defined relative position of the base part 2 and 3 Aufsetzteil each other is then, as in Fig. 7 shown, the through hole 28 created consistently, so that now the side by screwing the corresponding screw (s) (30), the base part 2 and the attachment part 3 of the post connector 1 can be interconnected and locked.

This is the in Fig. 6 reached shown end position, wherein in the representation of Fig. 6 the presence of screwed fastening screws 30 is indicated only in principle. By means of this screw (s) 30 in the through hole 28 is now a secure and firm fit between the base part 2 and attachment part 3 of the post connector not only together, but also on the frame part 4 and the post 5 created.

The lateral screwing the mounting screws 30 is easily feasible in the superimposed mounted final state of the base part 2 and 3 Aufsetzteil, on both sides of the post 5. Thus, an extremely rapid assembly of a post 5 on a frame strip 4 by means of the inventive post connector 1 can be created , which - if desired - can also be undone by unscrewing the screws 30 from the through hole 28 again.

The presentation of the Fig. 8 shows an enlarged sectional view through a post connector in the assembled final state, according to cutting position VIII - VIII in Fig. 7 , This cutting position also passes centrally through a guide rail 22.

In the similar sectional view from Fig. 9 , but now the cutting position IX - IX off Fig. 7 corresponds, is in the region of the through hole 28 of the section through the body 10. In the representation of the Fig. 9 However, for the sake of simplicity, the fixing screws 31 for fixing the base body 10 at the top of the frame strip 4 as well as the corresponding threaded holes have been omitted last.

In the figures, for ease of understanding of the same on the representation of not important for understanding the invention constructive elements such. As seals o. Ä., Waived, although such structural elements in the practical embodiments of the invention are also quite used.
