The carrying sleeve is located axially and radially in at least one of the boreholes of the frame, and the threaded dowel locates in the carrying sleeve. The carrying sleeve location can be achieved via a simple press fit into the bore or via a self tapping external thread or via a cone which presses into the bore.

Description

The invention relates to a device for fastening a Fitting in a frame according to the preamble of claim 1.

DE 30 45 372 A1 describes a device of this type Fastening a fitting in a thermally insulated frame knows. The frame consists of two metal profiles that pass through heat-insulating plastic webs connected to each other and be are kept apart. A support bushing passes through holes of a metal profile and sits with its front end in a hole in the second metal profile. The support bush will axially clamped between the two metal profiles. For this the support bush is supported axially with its front end on the second metal profile, while the rear end of the support bushing is screwed into a pressure plate with an external thread, which in turn is supported on the first metal profile. A Ge The fitting's wind pin penetrates the support bushing freely and is screwed into a transverse nut with its front end, which engages behind the second metal profile. The grub screw will thus with the help of the transverse nut axis axially on the first and the clamped second metal profile, the support bushing with the Pressure plate from the tensile forces generated by the grub screw supports to relieve the heat-insulating plastic webs.  

Frames are increasingly being made for doors and windows a hollow profile made of plastic, in which a me tallprofil is used for reinforcement. With such frames the metal profile sits relatively loosely in the hollow plastic profile and is only with a few screws with the plastic hollow profile connected. Manufacturing or age-related measure lerances can therefore lead to a loosening of the metal profile the plastic hollow profile. Are fittings in conventional Licher way with a grub screw in the plastic hollow profile and attached to the reinforcing metal profile, one leads such loosening of the metal profile compared to the hollow plastic profile also to loosen the set screw and thus of the fitting to the frame.

The invention has for its object a device for Fastening a fitting in a frame made of a hollow profile to create that in a simple way a permanently stable The fitting is held in relation to the frame.

According to the invention, this object is achieved by a device with the features of claim 1.

Advantageous embodiments and developments of the invention are specified in the subclaims.

The invention is based on the idea of a frame made of a plastic hollow profile and one used for reinforcement th metal profile, which is the set screws of the fitting inserting supporting bushes in such a way that they Boh in the opposite walls of both the Enforce hollow profile and the metal profile and in the Bores in the press fit can be determined. This makes the support axially and radially fixed bushings and the fitting is permanent fixed in the frame when the grub screws fit into the frame because the bushing is screwed in so that it is stable in the support bushing and thus sit in the frame.  

The support bush is not only used to fasten the fitting, but also fixes the plastic hollow profile and that Metal profile against each other. Even if between the metal profile and the surrounding plastic hollow profile or age-related dimensional tolerances do not result to loosen the metal profile compared to the hollow plastic profile and therefore not to loosen the grub screw and the fitting opposite the outer plastic frame.

The attachment of the support bush in the press fit in the frame instructs their outer circumference at least one outer cone, which is on an excess compared to the diameter of the bore expanded, so that the support bush with this outer cone axially in the fit Hole can be driven. Can continue in the inner cross cut the support sleeve be formed an inner cone, so that the support bushing radially when screwing in the grub screw expanded and pressed into the hole. The can continue Support bushing be axially slotted to form sector wings that through the screwed-in grub screw to the outside against the hole spread and clamped in the hole. Finally the bushing can have a self-tapping external thread point, which cuts into the profile of the frame and creates a positive and non-positive fit. This under Different versions of the support bushing can also be used together be combined.

Preferably, the support bushing is on both diametrical sides, d. H. at the front and at the rear end in the frame fixed, which is a particularly stable and lasting Fastening in the frame results. In this case it is preferred point the front end of the support bushing over an inner cone expanded, while the rear end of the support sleeve by means of Outer cone is set. The effect of the outer cone can additionally by expanding the support bushing using a Inner cone are supported when screwing in the setscrew. The grub screw is useful at its front end a conical tip.  

The support sleeve can be made of plastic or metal. Before sometimes plastic or a soft metal is used, so that the grub screw is self-tapping into the bushing can be screwed without the support bushing having an inner flange winch must be provided. It also facilitates plastic or a soft metal expanding the bushing when screwing in of the grub screw.

It is also possible to add an anti-rotation device for the Carrying sleeve to be provided to prevent turning when screwing in the Ge to prevent wind sticks. For this, the support bushing can approach have surfaces to the support bushing, for example by means of a To hold the wrench. The inner cross can continue cut the support bushing in relation to the external cross section be designed axially offset. Will be multiple support bushings used, they can be connected to each other by an outer web be connected, which holds them against twisting.  

Even if the invention with regard to the attachment of the fitting is described in the frame of the door or window reveal, is the same fastening of the fitting in the frame a window or door leaf can be used.

In the following the invention based on in the drawing illustrated embodiments explained in more detail. It shows

Fig. 6 in an exploded view of a third exemplary embodiment and

Fig. 7 in an exploded view from a fourth exemplary embodiment.

In Fig. 1 a partial section of a frame 10 is shown, which is formed by an extruded plastic profile. In a hollow channel of the frame 10 , a metal profile 12 is inserted. The metal profile 12 has the shape of a square hollow profile, the outer contour of which corresponds to the inner contour of the hollow channel of the frame 10 , inwardly projecting ribs of the frame 10 compensating for manufacturing tolerances between the hollow channel of the frame 10 and the metal profile 12 . By means of a fitting, a wing 14 is pivotally attached to the frame 10 . The wing 14 also has a plastic profile.

In the example of FIG. 1, a three-part fitting is shown, which consists of two tape rolls 16 , which are fastened to the frame 10 , and one between these tape rolls 16 is arranged tape roll 18 , which is attached to the wing 14 . The tape roll 18 is rotatably supported by an axle pin 20 with respect to the tape rolls 16 .

The tape roll 18 is screwed into a bore 24 of the wing 14 by means of a radially projecting thread pin 22 .

The fastening of the band rolls 16 in the frame 10 is shown schematically in FIGS. 2 and 3. Holes are made in the frame 10 and the metal profile 12 , so that holes 26 and 28 in the frame 10 and holes 30 and 32 in the metal profile 12 are produced. The bores 26 , 28 , 30 and 32 are axially aligned, the bores 26 and 30 on the one hand and the bores 28 and 32 on the other hand adjoining one another and the bores 30 and 32 lying in the profile sides of the metal profile 12 lying opposite one another.

In the bores 26 to 32 , a support bushing 34 made of plastic or a soft metal is used. The support sleeve 34 has an outer collar 36 at its rear end, which serves as an axial stop when the support sleeve 34 is inserted. If the bushing 34 is axially inserted so far that the collar 36 rests on the outside of the frame 10 , the bushing 34 penetrates with its rear end the bore 26 of the frame 10 and the bore 30 of the metal profile 12 , while the front end of the bushing 34th penetrates the bore 32 of the metal profile 12 and the bore 28 of the frame 10 . Subsequently, a set screw 38 , which is attached to the respective band roller 16 and protrudes radially, is screwed into the support bushing 34 . The threaded pin 38 cuts into the inner cross section of the support bushing 34 with its thread. The support sleeve 34 is pressed with its outer circumference into the holes 26 to 32 , as indicated in Fig. 3. In this way, on the one hand, the setscrew 38 is held firmly in the support bush 34 and, on the other hand, the metal profile 12 is fixed in the frame 10 by the support bush 34 in the region of the bores 26 and 30 on the one hand and the bores 28 and 32 on the other hand.

Exemplary embodiments for the design and fastening of the support bushing 34 in the bores 26 to 32 are described below. Since the formation and fixing roll for the band formed consistently 16, only the attachment of a tape roll 16 will be described respectively. Otherwise, the tape rolls 18 attached to the wing 14 can be attached in the same or a corresponding manner.

In the embodiment of FIG. 4, the support bushing 34 has a straight cylindrical outer circumference. The front end of the support bush 34 is formed with an insertion cone 40 , which facilitates the insertion of the support bush 34 into the bores 26 to 32 . The outer diameter of the support bushing 34 corresponds to the diameter of the bores 26 to 32 . At its rear end, the outer diameter of the support bushing 34 widens with an outer cone 42 towards the collar 36 . The wide end of the outer cone 42 has a slightly larger diameter than the bores 26 to 32 . The inner passage 44 of the support bushing 34 runs coaxially with an inner diameter which corresponds to the core diameter of the threaded pin 38 . If the threaded pin 38 is screwed into the carrying bush 34 , its external thread cuts into the wall of the inner passage 44 of the carrying bush 34 . In the axial region of the bearing sleeve 34, in which the outer cone 42 attaches, has the internal passage 44 to a cross-section of the inner passage 44 narrowing inner cone 46th The inner cone 46 extends over a small axial length and narrows in Rich direction on the front end of the support bushing 34th At the front end of the support bushing 34 , the inner passage 44 narrows again in a corresponding manner with an inner cone 48 .

The support bushing 34 is axially struck in the bores 26 to 32 until the collar 36 abuts the frame 10 on the outside. The outer cone 42 is pressed into the bore 26 of the frame 10 in a press fit. The rear inner cone 46 is located in the region of the bore 30 of one wall of the metal profile 12 , while the front end of the support bush 34 with the inner cone 48 in the region of the opposite wall of the metal profile 12 and the frame 10 in the holes 32 and 28 located. Now the grub screw 38 provided with a conical tip 50 of the tape roll 16 is rotated into the support bush 34 . The grub screw 38 widens radially in the region of the rear cone 46, the support bushing 34 and presses the se into the bore 30 of the metal profile and the adjacent bore 26 of the frame 10 . If the threaded pin 38 is fully screwed into the support bush 34 , its conical tip 50 widens the front end of the support bush 34 over the inner cone 48 and presses the front end of the support bush 34 into the holes 32 and 28 .

Around the support sleeve 34 rotationally fixed when screwing in the threaded pin 38 to keep the collar may have on its outer periphery surfaces 52 approach 36 so that the bearing bush can be held against rotation by means of a wrench 54 34th

In Fig. 5, a second embodiment of the support bush 34 is shown ge. Unless otherwise specified below, the support bushing 34 can otherwise be designed in the same way as the support bushing of FIG. 4.

To fix the support bushing 34 in the bores 26 to 32 , the support bushing 34 has axial slots in its outer surface, through which segment tongues 56 are formed, which are spread out by means of an inner cone when the threaded pin 38 is screwed in. The segment tongues 56 are axially arranged on the support sleeve 34 so that they are in the area of the bore conditions 26 to 32 when the support sleeve 34 is completely hammered into the frame 10 up to its collar 36 . When the threaded pin 38 is screwed in, the segment tongues 56 are spread out and pressed against the edges of the bores 26 to 28 in a press fit.

In order to keep the support bushing 34 against rotation when the set screw 38 is screwed in, in the exemplary embodiment in FIG. 5 the axis of the inner passage 44 is offset eccentrically with respect to the axis of the outer cross section of the support bushing 34 . The torque acting on the support bush 34 when the setscrew 38 is screwed in does not therefore lead to a rotation of the support bush 34 in the bores 26 to 32 .

As an alternative to this eccentric arrangement of the internal passage 44 , the collar 36 can of course also be formed with attachment surfaces 52 in this embodiment.

In FIG. 6, a third embodiment of the support sleeve 34 is shown. Here, too, the support bushing 34 is designed as in the previous embodiments, unless stated otherwise below.

In the embodiment of FIG. 6, the support sleeve 34 has a Außenge thread 58 adjacent to the collar 36 on its outer circumference. The external thread 58 has a core diameter which corresponds to the diameter of the bores 26 and 30 . The support sleeve 34 is axially in the bores 26 to 32 until the external thread 58 meets the bore 26 of the frame 10 . Then the support bushing 34 is screwed in, the external thread 58 cutting into the bores 26 of the frame 10 and the bore 30 of the metal profile 12 . With the external thread 58 , the support bush 34 then sits firmly in the Boh stanchions 26 and 30th

For screwing in the support bushing 34 , the inner passage 44 in the region of the collar 36 is expanded to form an internal hexagon 60 .

A fourth exemplary embodiment is shown in FIG . In this embodiment, the support bushings 34 can be designed in the same manner as was explained in the preceding examples.

In contrast to the previous examples, to secure the support bushings 34 against rotation when screwing in the threaded pins 38, the support bushings 34 used next to one another in the frame 10 are connected to one another at their collar 36 via a web 62 . The web 62 lies on the outside of the frame 10 when the support bushings 34 are inserted in the bores 26 to 32 .

In the embodiment of FIG. 7, a five-part band is also shown, which has three band rolls 16 on the frame 10 and two band rolls 18 on the wing 14 .
