Abstract

The connector (10) is fitted with its entire volume in the hollow space (13) of the first section rod (11). The recess (16) which receives the connecting end (15') of the connection device (15), is open sideways transverse to the first section rod.

Description

The invention relates to a one-piece connector a T-connection of two profile bars, which in one Cavity of a first profile bar, which is closed laterally all around used and attached to it with a continuous fastener is attached, and the one with the first Profile rod parallel connecting means with a second, is connected at the end face of the first arranged profile bar, the form-fitting with an attack end in the connection direction is arranged in a recess of the connector.

Such a connector is well known to a Establish fighter connection, namely the connection of the first Profile bars on the second profile bar of a door or Window frame in the area between the ends of the second profile bar. The connector is attached to second profile bar by means of components of the connector that protrude radially from the profile circumference of the first profile bar and so one from the outside from areas next to the profile bars allow attachment to take place. Such an attachment e.g. by screwing the side protruding Components of the connector with the first and / or with the second Profile bar. The side from the profile scope of the first Profile rod protruding components of the connector are also directed parallel to the first profile bar, namely in the form of fastening tabs through which the fasteners are inserted be with the first profile bar can be braced. Training the connector with the protruding from the profile circumference of the first profile bar Components require special effort in the manufacture of the Connector. It is not just a considerable amount of material before, but a workpiece to make the connector is also comparatively complex and must be used as an injection mold Have cores to create undercuts to be able to. Such tools are complex and accordingly expensive. In addition, connectors are made with the Profile scope of the first profile rod projecting components often criticized for the fact that these components are unsightly be and disturb.

In contrast, the invention is based on the object a connector with the characteristics mentioned above improve that he is not laterally out of the scope of the profile first protruding profile protruding components, anyway ensures the required stability between the profile bars and moreover with the simplest possible molds is to be produced.

This object is achieved in that the connector practically with its entire volume in the cavity of the first Profile staff is housed and the attack end of the Connection means receiving recess transverse to the first Profile bar is open on the side.

It is important for the invention that he completely housed in the cavity of the first profile bar is. There are no sideways from the profile of the first Profilstabs protruding components available that interfere could, or which require a special manufacturing effort. Nonetheless, the means necessary to determine are of the connector both on the first profile bar and on second profile bar available. This means of establishing namely the fasteners penetrating the first profile bar transversely and the connecting means parallel to the first profile bar, can be arranged within the connector be that the structures accommodating them are easy to manufacture are. This is particularly the end of the attack of the connecting means receiving recess transverse to the first Profile bar open on the side. So it’s not necessary to produce this recess, the manufacturing tool use expensive core. The connector may preferably be designed so that it is metallic if necessary Injection molded part that is formed in two each other parallel planes perpendicular to the second profile bar has vertical functional projections exclusively for these. This configuration also complements the shape of the Connector in the sense of a design that with simple Injection molds is to be produced. The functional advantages are used primarily to adapt the shape of the connector to the profile of the cavity, so that a functional All-round support of the connector is made possible and to achieve the required strength of the connection is.

In further training of the aforementioned design idea it is preferred that the functional protrusions and the side open recess in the same, parallel to the second profile bar Are oriented. It simplifies training a manufacturing tool, the functional projections and the laterally open recess-producing shaped elements are all oriented parallel to each other.

The connector can be designed such that he a solid one, the two perpendicular to the second profile bar Disc-like or frame-like planes defining them Has core from which the functional projections in parallel Project to the second profile bar. The disc-like core the connector in particular contributes to its stability. The lanyards or the fasteners have a stable hold. The disc or block-like core will therefore meet the strength requirements designed and dimensioned accordingly. So he saves Material than that between it and the cavity of the first Areas of the profile bar are not filled with material Need to become.

The connector can be designed such that the functional projections on mutually parallel inner walls of the Adjacent cavity of the first profile bar, or that they accordingly a stiffening profile placed over the connector are shortened. Those adjacent to the interior walls of the cavity Functional projections stabilize the connector within the first profile bar or form optimal supports for fastening and / or connecting means. The Functional tabs can also be shortened. It arises thereby space for arranging a stiffening profile, for example a slotted steel tube with which, for example plastic first profile bar against unwanted deformation is stiffened.

It is preferable that the functional protrusions have wall sections of the outer peripheral walls of the disc-like or frame-like Are the core of the connector. With the wall sections the disc-like core can line up with the inner walls of the cavity of the first profile bar are supported, so that selective loads are avoided. The wall sections and the outer peripheral walls can be plate-like structures be that a distance to the the connecting means have exhibiting areas. Such structures can be frames form that serve to save material.

To achieve an optimal connection strength in the area of To obtain connecting means, the connector can be designed in this way be that the transversal fasteners arranged in a bore parallel to the second profile bar are, the bore wall between the entire length between the mutually parallel inner walls of the cavity of the first Profile rod or a cavity of the plugged over the connector Stiffening profile extends. As a result the total distance between the two parallel inner walls of the cavity within the connector for coupling Available, so that there is a correspondingly good positive Connection strength results.

The connector is in the area of the connecting means Conveniently designed so that its laterally open T-shaped recess with a head of a connecting screw or a connecting nut receiving abutment space is trained. The laterally open T-shaped recess allows connecting screws designed as cap screws or use connecting nuts to to attach the connector to the second profile bar. The The use of these connecting elements is optional.

The connector can be designed such that the laterally open recess in the longitudinal axis of her recorded connection means with an actuating hole is extended. The actuation hole allows one Insert a tool, for example a screwdriver or a wrench that holds the lanyard is twisted, for example a connecting screw, the thereby their relative position to a fixed connecting nut changes and consequently loosening or fastening allowed to reach the connector. Such Actuating hole is particularly necessary if the connector is attached to the second profile bar before it is coupled with a first profile bar. That in turn is particularly necessary in the case of a cross connection which is a connector with one on the opposite side of the second profile bar arranged by means of a connector Connection screw is coupled.

There is one configuration in connection with the actuating bore of the connector advantageous, in which the actuation hole distributed alternately along its length the second profile bar has parallel access recesses. On the one hand, the access recesses save material, but primarily serve that with a mold Actuating bore are produced in sections can what the access recesses in turn arranged are, namely the second profile bar parallel that the application a coreless manufacturing tool is possible.

A preferred further development of the connector is then, if he has a recess surrounding the laterally open recess, support projection that can be supported on the second profile bar from a room for the connection means letting sealing plate is surrounded, if necessary keep the entire distance between a glazing bead and a rollover of the second profile bar seals. Consequently can the connector with the second profile bar be rigidly connected, with the support projection directly supported on the profile bar. The support is particularly independent from sealing the connector against the second Profile bar, which are caused by a sealing plate can. The sealing plate can be designed so that it the entire distance between a glazing bead and seals a rollover of the second profile bar. It is then ensures that moisture transport in the area of second profile bar from one side of the first profile bar is prevented on the other side. Also from the area or in the area of the connection means is moisture transport locked out.

This will further improve the connector characterized in that it has a toolbar, which is in a The glazing bead retaining groove of the second profile bar engages. It results in particular an improved securing of the connector against twisting or torsion around the first profile bar parallel axis. Also the connection strength of the connection means is thereby secured.

an exploded view of a cross connection consisting of two T-connections.

The T-connection shown in Fig.1 is between two profile bars 11, 12 are made. Each profile bar is as Hollow profile rod formed with a central cavity 13. Their walls inside the room are just as aligned as their outside walls Walls formed by rollovers 33. The first profile rod 11 is profiled at its end that he with his rollover 33 on the rollover 33 of the fits second profile rod, being between the ends of this second profile bar 12 is arranged while the body 11 ', 12' of both rods are sealed together.

The two rods 11, 12 are fastened by means of a connector 10, which is formed as a one-piece component and in a cavity 13 of the first profile rod 11 or of the rod body 11 'is housed. The connector 10 is completely within the side all around closed Cavity 13 of the profile rod 11 arranged so that it laterally or radial to the rod 11 not over its outer circumference protrudes. When installed or when manufactured The connector 10 is not from the outside visible.

The connector 10 must both be attached to the profile rod 11 be, as well as on the profile bar 12, on the side wall 12 '' of the connector 10 is attached. The attachment the connector 10 with the rod 11 serve fastening means 14, shown only schematically in the figures are. The fastening means 14 consist, for example a screw sleeve with internal thread, which is from one side of the Rod 11 inserted through a hole 35 in the connector 10 and in its internal thread from the other side of the Rod 11 a screw is screwed through a hole 36, which is clamped with the threaded sleeve. The fasteners 14 engage in a bore 26 of the connector 10.

The coupling of the connector 10 with the second profile bar 12 takes place via connecting means 15, which are shown in the figures are also shown only schematically. After all, is in 2 to recognize that the connecting means 15 from a Cap screw 24 with a head 24 'and an attack end 15 'has. The connecting means 15 is through a through hole 37 or two such holes in the rod body 12 ' inserted into a recess 16 of the connector 10. This recess 16 is T-shaped and open on the side. Part of the recess 16 is an abutment space 27, which forms the roof of the T-shape. In the abutment space 27 is as part of the connecting means 15 a connecting nut 25 used, which is aligned with the attack end 15 ', so that this is screwed into the connecting nut 25 can be. The head 24 'of the connecting screw 24 on the wall opposite the connector 10 of the rod body 12 '' and the connecting nut 25 if the connecting screw is turned accordingly 24 seek to draw in. As a result, the squeezes Connection nut 25 the connector 10 against the rod body 12 ''. At the same time, the end face of the profile rod 11 pressed firmly against the adjacent wall of the rod body 12 ″, since the connector is fastened by the fastener 14 is connected to the end of the rod 11.

To assemble the connecting means 15 is the connecting nut 25 in the laterally open recess 16 or in the abutment space 27 held clamped. Fig.3c shows Clamping cams 38 in the form of narrow, in the direction of insertion the nut 25 arranged cutting ribs. These cutting ribs when inserting the nut 25 into it and hold on tight.

The connector 10 has a disk-like core 20, except for the recess 16, the bore 26 and an actuating bore 28 as well as related access exceptions 29 can be solid. This Core 20 is delimited by two levels 17, 18 according to FIG when the connector 10 is installed perpendicular to the second profile bar 12 are arranged. From levels 17, 18 of the disc-like Kerns 20 project functional projections 19, 19 '. Such Functional projections are strip-like or wall section-like educated. E.g. Figures 2,3e, 3f leave rod-like Functional projections 19 and 19 'recognize which the disc-like core 20 on an inner wall 21 or 22 of the Support cavity 13 of the first profile rod 11. Two in line, Functional projections pointing in opposite directions 19 thus serve the positioning or Seat of the connector 10 in the cavity 13 between two each other parallel inner walls 21,22 of the profile rod 11. The same Function take over wall sections 39, which e.g. according to Fig.3a from an outer peripheral wall 40 of the disk-like core 20 of connector 10 project on both sides. Such According to FIG. 2, wall sections 39 are on two mutually perpendicular Outer peripheral walls 40 are present. All functional advantages 19, 19 'and the wall sections 39 ensure one Corresponding material savings, since the disc-like core 20 of the connector 10 has a comparatively small thickness must have, which is due to the recess 16.

The core was previously described as disk-like. He but can also be designed like a frame. Then that is the one Case when the space between those at right angles to each other standing outer peripheral walls 40 and from the perspective Representations of the Fig. 2.5 visible, in particular the wall 16 forming the recess is left free of material. This is the space in which the Fig.3b, 3c Reference numeral 20 is located. Such a frame-like training of the core 20 leads to a considerable material saving, where the rigidity of the connector 10 by the width of the outer peripheral walls 40 transverse to the first profile bar 11 remains guaranteed. The hole wall 26 ' the bore 26 for the fastener-forming core wall part jumps across to the profile bar 11 as far as the Walls 40 with their wall sections 39, so that a corresponding Stabilization of the connector 10 also in the middle area between the parallel outer peripheral edges is.

3f shows that the functional projections 19 ' are shorter than the functional projections 19 because of a stiffening profile 23 is present, which is about the same length, as the profile bar 11. The stiffening profile 23 overlaps as a result, the connector laterally near the two Levels 17, 18, but its support by the functional projections 19 'or correspondingly shortened wall sections 39 remains guaranteed.

So that the connector 10 is firmly connected to the profile rod 12 is in the area of the recess 16 Support projection 30 available. The support projection 30 surrounds the Recess 16 and has clamping cams 30 'at its lower end, which are pressed into the material of the profile bar 12 can and thus contribute to improving the connection strength.

An actuating bore extends above the recess 16 28 coaxial with the longitudinal axis of the connecting means 15. Starting recesses extend from here 29 on both sides of an axis 28 'of this bore 28 alternately perpendicular to both planes 17, 18. That makes derives in particular from Fig.3g. These access recesses 29 serve on the one hand to save material, but on the other hand improved manufacturability. This is particularly the case from Fig. 4. Here are schematically shown molds 41,42 shown, only with regard to their front Profiles 41 ', 42' are so detailed that their effect the manufacture of the connector 10 can be explained. Will you pushed together in the directions of the double arrows 43, so they occupy all the free spaces of the connector, unless the 3a to 3g apparent massive shapes are to be produced by injection molding. For example a projection 44 to a position in which it is perpendicular round edge 45 of bore 28 to the plane of representation shape that is as high as its thickness. Several mutually attached to the tools 41, 42 Projections work together. The area 46 of the tool 42 is formed in the display plane and perpendicular to it, that it allows the recess 16 to be made. The tools 41,42 are also designed in a manner not shown that the receiving the connecting means 15th allow to produce serving bore 26, as well as all others Recesses of the disk-like or frame-like core 20, each associated with corresponding material savings. The also applies to the space 47 designated in FIG Functional projections 19 shown there above and below.

All figures show a function bar 34, which are arranged in alignment with one of the outer peripheral walls 40 is that they are in the glazing bead retaining groove 32 of the profile bar 12 is able to intervene. It gives the connector 10 a special stiffness against twisting the first Profile bars 11, which also includes its precise fit with the Functional projections 19, 19 'within the cavity 13 and the fasteners 14 contribute.

A sealing plate is used for sealing in the area of the connector 31 provided from an elastic Material is made, for example from a synthetic rubber. The sealing plate 31 encloses the support projection 30, but leaves space to carry out the lanyard 15. The sealing plate 31 is dimensioned so that when tightening the connector 10 or the profile bar 11 is slightly deformed against the profile bar 12 and thereby seals.

The assembly of the connector 10 or the manufacture of the T-connection takes place in such a way that the connector 10 in the cavity 13 of the profile rod 11 is used. Then be the fasteners 14 inserted through the holes 35,36 and screwed together, for example. Then will the sealing plate is attached to the support projection 30. Then the profile bar 11 is placed on the profile bar 12, in such a way that the connecting means 15 are brought into action can be. The connecting screw 24 is through the Through holes 37 of the profile bar 12 inserted and in the Connection nut 25 screwed in before installing the connector was installed in the abutment space 27.

5 shows an exploded view similar to FIG with two T-connections, which together form a cross connection form. In this case there is a lower additional connector 10 to apply, together with a connecting means 15 is attached to the upper connector 10. The one there the connecting screw 24 used is corresponding longer and becomes with her head in the not visible in Fig.5 Abutment space 27 of the lower connector 10 arranged, inserted through the through holes 37 and into the connecting nut 25 of the upper connector 10 screwed. The Screw actuation is carried out by a also from Fig. 5 not visible operating hole 28 of the lower connector 10, that of the actuating bore described in FIGS. 2 to 4 28 corresponds. After attaching the bottom Connector 10 together with the upper connector 10 or its Profile rod 11, the lower profile rod 11 over the lower Connector 10 inserted and the lower fasteners 14 are used as described above.
