to be or to be prefabricated at regular intervals. The shaping of a nut thread profile on the inner flanks of the profile webs of the first shell profile is already known with its drawing process, so that a nut thread for receiving the screw thread is present from the start on the first shell profile at the desired screw location. At the screw-in point, the screwed-in screw shaft also stabilizes the profile webs of the first shell profile in such a way that they cannot retract inward from their latching position with respect to the H-legs of the plastic profile. Furthermore - also in its special embodiment according to the characterizing feature of claim 2 - the screw head additionally has a stabilizing effect on the H-legs of the plastic profile which are in the engaged position with the inner profile and which, as a result, also cannot withdraw from their latched position with respect to the inner profile.

The characterizing feature of claim 3 ensures a limited deflection behavior of the H-webs of the plastic profile and / or the profile webs of the shell profiles when pushed together for mutual releasable locking. The characteristic of claim 4 serves to facilitate the latching movement.

A stabilization of the position of the individual parts of the composite profile relative to one another is ensured by the characterizing feature of claim 5. The same purpose is served by the characterizing feature of claim 7, by which - based on the central longitudinal plane of the composite profile - a lateral deflection of the H-legs from their final locking position and thus a loosening of the mutual positive connection is reliably prevented. This effect is particularly supported in the area of the ends of the H-legs facing the outer profile by the characterizing feature of claim 6. The production of such composite plastic profiles in an extrusion process is known.

The characterizing feature of claim 8 serves to facilitate the preparation of the plastic profile for the approximately identical implementation of a crossing inner profile in a rung cross for the assigned second shell profile. The H-legs of the plastic profile facing the second shell profile only need to be milled out up to the height of the screw head contact surface in order to carry out the second shell profile of a plastic profile crossing in the area of a crossbar roughly the same as the second shell profile assigned by the plastic profile from home. The screw head contact surface of the plastic profile thus serves to a certain extent as an end limitation for such a milling process.

By the characterizing part of claim 9, the plastic profile is stabilized in itself. The thermal insulation effect is improved by creating additional air chambers in the area of the plastic profile.

Claim 10 relates to a rung cross made from the composite profiles explained above, preferably with identical rungs. The manufacture of a stable cross-bar of this type is made considerably easier by the characterizing features of claim 10. At the point of intersection of the plastic profiles that have intermingled with each other, the plastic profile of the one rung is connected to the second shell profile of the other rung by a screw of the same type that is otherwise used to manufacture only the composite profiles according to the invention, with the interposition of the plastic profile assigned to the other rung.

The object of the invention is explained for example with reference to the figures. Show it:

1 shows an enlarged cross section through a composite profile constructed according to the invention.

Fig. 2 is a crossbar made with the composite profile according to the invention in an exploded view.

The composite profile (Fig. 1) for thermally insulated rungs on window panes consists of two aluminum shell profiles 1, which are connected to each other by a plastic profile 2. The shell profiles 1 form the profile inner and / or outer shell.

The plastic profile 2 essentially has the cross-sectional shape of an H, the vertical H-legs 3, 4 of which lie in the spacing direction 5 between the two shell profiles 1. The shell profiles 1 are provided on their inner sides with two essentially parallel to each other, also in the direction 5 of the plastic profile 2 projecting profile webs 6 and 7 respectively. With these profile webs 6 and 7 they can be pushed onto the plastic profile 2 in the spacing direction 5 and in the end position in the slide-on position (FIG. 1) they can be snapped together with the plastic profile 2 automatically in a barb-like manner. The profile webs 6 of the first shell profile 8 lie with their outer flanks 9 facing away from one another on the inner flanks 10 of the H-legs 3. The profile webs 7 of the second shell profile 11 lie with their mutually facing inner flanks 12 on the outer flanks 13 of the H-legs 4.

The inner flanks 43 of the profile webs 6 of the first shell profile 8 are provided with an advanced thread for receiving a screw 14 passing through the plastic profile 2 parallel to its H-legs 3, 4 in the direction of distance 5, the head 15 of which connects the connecting web 16 of the H-legs 4 its side facing away from the first shell profile 8 in the area of the loading surface 17. The screw head 15 is a round head and lies with its circumference on the inner flanks 18 of the adjacent H-legs 4 of the plastic profile 2.

The snap-in protrusions 19, 20; 21, 22 of shell profiles 1 and plastic profile 2 are arranged in the region of the adjacent web or leg flanks. The same applies to the clamping recesses into which the clamping projections 19, 22 snap into place. The clamping projections 19-22 are provided on their rear sides facing away from the clamping contact surfaces 23 with bevels 24. The ends of the plastic profile 2 abut the shell profiles 1 with the ends 25, 26 of its H-legs 3, 4. The ends 25 of the H-legs 3 of the plastic profile 2 facing the first shell profile 8 lie in the snap-in end position of the first shell profile 8 between the profile web 6 flanking them and a centering web 27 molded onto the first shell profile 8, so that they do not move laterally outwards in the direction of the arrow 28 can dodge. While the load-bearing part of the plastic profile 2 consists of hard PVC, the ends 25, 26 of the H-legs 3, 4 are made of soft PVC in order to ensure a higher elasticity there. The ends 29 of the profile webs 7 of the second shell profile 11, which is in its snap-in position, lie approximately at the same height as the contact surface 17 of the screw head 15 on the connecting web 16 of the plastic profile 2. A plurality of connecting webs 16, 30, 31 are arranged parallel to one another and close corresponding air chambers 32, 33 between them.

The crossbar shown in FIG. 2 consists of two composite profiles according to FIG. 1 which cross each other at the same time. The plastic profiles 2 of these composite profiles cross each other in a mutual lamination34. This is

in the distance direction 5 from the H-legs 4 of the vertical plastic profile 2 up to approximately into the middle of the profile, a furrow groove 35 of a width corresponding to the width 36 of the plastic profile 2 is introduced. The horizontal plastic profile 2 carries a corresponding spline groove 37, which however starts from the H-legs 3 facing the outer, first shell profile 8 and also extends approximately to the middle of the profile. The two plastic profiles 2 are plugged onto one another in the area of the leafing 34, whereby they assume the same position relative to one another. The furrow grooves are made by milling.

The horizontal, one plastic profile 2 is provided below for better differentiation purposes with the reference number 38 and the vertical, other plastic profile 2 with the reference number 39. The horizontal plastic profile 38 is screwed into the leafing 34 with the insert of the other plastic profile 39 with the vertical shell profile 8 which remains uninterrupted and assigned to the other plastic profile 39. The horizontal plastic profile 38 is in the region of its H-leg 4 adjacent to the screw head 15 with saw cuts or a cutout 40 for the passage of the likewise uninterrupted

the vertical, other plastic profile 39 assigned, vertical shell profile 11. The cutout 40 lies in the plane of the screw head application surface 17 of the connecting web 16. The horizontal shell profiles 11 and 8 of the horizontal plastic profile 38, which are interrupted in the cross region s, are in flank contact on the vertical shell profile associated with the vertical plastic profile 39 11 or 8 snapped attached.

io In order to produce a rung cross, only the spline grooves 35, 37 need to be introduced into the two plastic profiles 2 which intersect at the same time, and the plastic profiles 2 need to be faded to one another. Then, through the center of the intersection, the bore 15 41 for the screw 14 is made in the plastic profiles 2. Then the one plastic profile 38 is firmly screwed to the vertical, first shell profile 8 by inserting the other plastic profile 39 into a sheet. The remaining shell profiles 11 are then only snapped onto the plastic profiles 2 in the manner shown in FIG. 2, with mutual clamping of the clamping projections 19-22, the glass panes lying in the space 42 between the outer legs of the shell profiles 1.
