Description

Housing for attaching a fitting part to a hollow profile provided with an offset part

Technical field

BACKGROUND OF THE INVENTION The invention relates to a housing for attaching a fitting part to a hollow profile provided with an offset profile part by means of a fastening device extending through the fitting part, preferably a bolt, wherein an intermediate space is provided between the profile part forming the bearing surface and the wall of the hollow profile. facing the fitting part and the fastener engages in the recess (female thread) of the sleeve and wherein the sleeve permeates through the interspace and engages the hollow profile.

BACKGROUND OF THE INVENTION

With an increasing range, hollow profile frames made of plastic, in which a metal profile is inserted for reinforcement, are used for doors and windows. These are so-called multi-chamber profiles, which have very good thermal insulating properties due to the chambers pre-interlaced with reinforcement.

The fastening of the fitting part by means of a screw cannot be carried out on the extension profile, since otherwise the considerable forces transmitted by the fitting part would have to be absorbed by the plastic profile, but these are not adapted. The fastening takes place by screwing with the metal profile closest to the contact surface of the fitting part.

With this profile construction, the hollow chambers would have to be pre-lined with a metal profile in the hinge attachment area with suitable materials (wood, plastic, metal) so that the hollow chambers do not deform when screwed. This leaching is not experienced in practice, since the plastic profiles cannot be calibrated inside and therefore have very strong dimensional variations that would require a continuous adaptation of such inserts.

DE 35 21 783 C1 discloses a spacer sleeve for attaching a fitting part to a hollow profile encased by a pre-formed profile part comprising a frontly rotatable threaded sleeve facing against the fitting part and a frontly rotatable double bolt which bears against the front circumferential flange engages from the peripheral one side of the protruding wall passing through the threaded portion into the threaded piece and engages the other to the other side of the protruding threaded portion which is noaxial to the first threaded portion into the threaded sleeve. Disadvantageous in this embodiment, however, the wall of the collar wall after

The threaded piece must be transported to a position within the hollow section with a suitable auxiliary tool and held there in a position where the threaded hole in the threaded piece is flush with the hole in the front wall of the hollow section and with the hole in the offset section.

DE 196 07 029 C1 discloses carrier sleeves for attaching fittings to a hollow profile frame, which are used in a doorframe. The carrier sleeves penetrate the frame and the metal profile inserted into the frame, with the forging screws screwed into the carrier sleeves. The support sleeves are fastened in the openings of the frame and the metal profile, so that they also fix the metal profile in the frame. However, it is disadvantageous with these carrier sleeves that they have to penetrate the overall metal profile and therefore different lengths of carrier sleeves have to be prepared according to the shape of the hollow profile. In addition, the carrier sleeves represent potential cold bridges and thus reduce the isolation of the multi-chamber profile.

SUMMARY OF THE INVENTION It is therefore an object of the invention to provide a secure fastening of a fitting to plastic profiles in such a way as to facilitate the fitting of the fitting part and the adaptation of the sleeve to the respective hollow profiles.

SUMMARY OF THE INVENTION The invention provides a socket, a seating flange and an intermediate space, wherein the bearing surface

This object is accomplished by a sleeve for attaching a fitting part to a hollow profile provided with an offset profile part by means of a fastener extending through the fitting part, preferably wherein between the profile part forming the wall of the hollow profile the sleeve abuts an axial hollow profile directed here against the fitting part and the fastener (internal thread) of the sleeve, and wherein the sleeve penetrates through the space and extends into the hollow profile of the present invention, wherein the sleeve has at least one external thread through which the sleeve extends into the front wall of the profile member and the wall.

Since the sleeve has an external thread which engages the front wall of the profile part and the inner wall of the hollow profile, it can be screwed into the hollow profile in a simple manner from the front. This makes it possible to mount the fitting part securely in a simple installation. The considerable forces transmitted by the fitting part are absorbed by the housing. This, in turn, is fixed by its external thread in the profile part as well as in the hollow profile.

In a first preferred embodiment, the housing is formed in different parts.

In a further preferred embodiment, the outer thread of the housing has two sections of different diameters, which can - particularly advantageously - pass into one another, for example, a conical formed transition section, in order to facilitate the assembly of the housing.

In a further preferred embodiment, the sleeve engages with a further axial bearing surface of the fitting part in the direction opposite to the front wall of the inner wall of the hollow profile.

The sleeve then preferably comprises two axially inwardly threaded threaded parts, preferably the first threaded part being a threaded sleeve with an internal thread abutting against the fitting part and of which the other threaded part is pivotable from the front and has an external thread which is engaged with said internal thread. The axial spacing of the bearing surfaces is adjustable by this adjustment.

If the sleeve has a protrusion that extends through the inner wall and the bore contains an external thread, this results in better absorption of forces.

Advantageously, the second threaded portion is a double bolt that abuts a circumferential collar provided between the external threads against the front side of the inner wall of the hollow profile. The spacing of the bearing surfaces can be easily adjusted if the threaded sleeve is also pivotable from the front, which can be made possible by the tool mounting device. This modification also allows the sleeve to be securely fastened in the hollow profile. Without the need for a further threaded piece into which the sleeve would have to be screwed in this case, as is known, for example, from DE 35 21 783 C1.

Advantageously, the internal thread of the threaded sleeve is through and the screw is engaged with the internal thread. This also applies to the one-piece design with constant diameter male thread and also to the two-piece design of the housing. As a result, expensive machining of the sleeve or the second threaded part can be omitted in both cases. A single metric threaded hole is therefore sufficient for a one-piece housing. In a two-part embodiment, the screws must be reasonably short so that they do not interfere with the other threaded part.

In addition, an embodiment is possible in which the engagement of the screw in this treatment without costly internal thread is provided on the inside of the other threaded portion can produce the threaded sleeve and the fastening forces are embedded directly through the second threaded portion through the threaded portion penetrating the wall into the hollow profile.

Another embodiment has the particularity that the threaded portion of the other threaded portion that penetrates the wall and engages in the hollow profile is part of a screw.

In this case, the bolt has two separate threaded sections, the first threaded section being a metric thread which engages the second threaded portion, and the second thread is a special outer thread which can be adapted to the plastic / metal material combination and which engages in the hollow profile . This special treatment not only reinforces the profile with a sleeve, but also fixes the fitting part with a screw on the threaded sleeve and at the same time in the hollow profile.

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, a window sash (not shown) should be rotatably mounted on the stationary frame 3 by means of the hinge 2 only indicated. The hinge 2 comprises a hinge wing which forms a fitting part 4 intended to be fixed to a fixed frame 3 and which is to be fastened to the frame 3 by means of a screw 6, which sits with its head in a suitable recess 19 of the fitting part 4.

The hollow profile 7 of the stationary frame 3 is advanced on the windward side of a substantially flat profile part 10 which leaves an intermediate space 12, which in this case consists of two chambers separated by a wall 37, relative to the inner wall 11 of the hollow profile 7 of the fitting part 4. The intermediate space 12 is held by the plastic profile part 10, so that it reduces the heat transfer between the front, weathered and also the plastic hollow profile and so-called cold bridging is avoided.

On the side of the wall 11 facing away from the fitting part, the interior of the hollow profile 7 is provided with a metal fitting 14, which serves to reinforce the profile consisting of plastic and to absorb the tensile forces arising from the fixing of the fitting part.

In order to transfer the fitting part 4 of the fitting part in all circumstances through the intermediate crosspiece 2 to the metal fitting 14, a sleeve with an external thread 13 extends through the front wall 16, the interspace 12 and the partition wall 7 and engages in the hollow profile 7 to his metal armature 14.

The sleeve T is screwed into a slightly smaller groove 38 by means of a suitable tool acting in the transverse cut 18 so that its front side 30 is flush with the front side of the profile 16. The length of the sleeve is chosen such that, when screwed in, it also permeates all four bores 38 A, B, C, D lying on one line and also engages inside the metal fitting 14.

A screw 6 serves to fasten the fitting part 4 arranged on the sleeve 11. For this, the sleeve 1 has a through-center bore 9 (see FIG. 2) which is provided with a metric thread adapted to the metric external thread 15 of the screw 6.

After firmly tightening the screw 6, the force applied from the fitting part 4 is transferred to the end face 30 of the housing from the side of the fitting part 4 facing the front wall 16 of the profile part. As a result, the plastic profiles f and 10 are relieved and the tensile forces are absorbed by the metal fitting 14. Furthermore, the pre-formed profile part 10 is prevented from being deformed.

The length of the housing 1 is sized to span the interspace 12. Since it may, to some extent, engage in the hollow profile f, its length need not be adapted to the respective profile. In the embodiment shown in FIGS. 1 and 2, the screw 6 may still be of the same short length, which is sufficient to introduce the forces to be transferred from the fitting part to the profile.

The outer thread 13 of the housing 1 is adapted in its lateral shape to the plastic / metal material combination so that it can be screwed into

modified accordingly slightly smaller hole 38. In FIG 4 is shown next form of the housing according to invention marked as whole

It consists of a double bolt 22 and a threaded bush 22. The double bolt 22 has a circumferential collar 23 which forms a bearing surface perpendicular to the axis, with which the bolt abuts the side of the wall 11 facing the fitting part 4. A projection 24 extends from the peripheral collars 23 in the direction of the fitting part 4, which engages in the metal fitting 14 of the hollow profile 7. For this purpose, its external thread is also adapted to the material combination of plastic and metal. In the direction of the fitting part 4, i.e. according to FIG. 3 below, a further threaded portion 26 extends from the peripheral collar 23, which engages in a through-bore hole 32 of the threaded sleeve 22 (cf. also FIG. 4). To rotate the double bolt and to tighten the same in the wall 11 or in the metal fitting, another threaded portion 26 at the front, i.e. on the side facing the fitting part 4, is provided with a transverse notch 27 for engaging a screwdriver.

The threaded sleeves 22 have a diameter which is slightly larger, as the diameter of the opening 38A in the front profile, the part 10 and the diameter of the opening 38B in the partition wall 37. It has at its front end, i.e. in its front side 30 facing the fitting part 4, a notch 31 of a rectangular transverse cut to engage a screwdriver. The threaded sleeve 22 also has an external thread 13 corresponding to the first embodiment, but which has an opposite direction of rotation with respect to the external thread 28 of the projection 24 so that it does not come loose when the threaded sleeve 22 is tightened. Conveniently, the external thread 28 is also adapted to a combination of plastic and metal.

When assembling, the spacer sleeve is screwed on to the other with a threaded threaded part by a .22 sleeve

C, introduces a notch through the openings 38 A, B and 38, respectively

D and the projection 24, when engaging the screwdriver 27, tighten the hollow profile 7 or the metal fitting 14. In this case, the holes 38C, D are adapted to a smaller diameter of the first threaded portion. Then, by turning the threaded piece 22 with respect to the other threaded portion 26, when the screwdriver engages in the notch 31, the threaded sleeve 22 is rotated until its face is flush with the front wall 16 of the profile piece 10. The intermediate space or gap 12 is now firmly supported and cannot be deformed when the screw 6 is tightened.

The fitting part 4 is now fitted and the screw 6 is screwed through the fitting part 4 into the threaded bore 29 of the other threaded part 26 until it is tightened. In this case, the threaded hole 32 of the threaded sleeve 22 serves only to screw it onto the other threaded part 26. A separate locking pin of the threaded part 22 is not necessary in this embodiment, since the threaded sleeve 22 does not exert rotational displacement when the screw 6 is tightened.

In another embodiment of the housing 101 of FIG

invention evident from FIG, 5, which otherwise it corresponds that which is described in Fig. 3 a 4 a it is referred to , has screw 106 thread 134. which also as thread 133

According to how far the threaded sleeve 122 is screwed onto the other threaded part 126, as in the previous embodiment, different gaps 112 between the inner wall 11 and the front wall can be spanned. 16 (see FIG. 3) In this case, the screw 106 is not touched from there and can still be of the same length. In this case, the screw length 106 is to be selected such that the maximum length is not exceeded, since otherwise it would otherwise strike another threaded portion 126 when tightening.

In a further embodiment of the housing 201 according to the invention shown in FIG. 6, it is a peculiarity to that described in FIGS. 3 and 4 that the projection 224 of the threaded portion 226, which is permeable to the inner wall and engages in the hollow profile or metal (see FIG. 3) is part of the screw 206. Analogously to the second embodiment, the screw 206 engages the first metric thread of the through portion 226.

234 to the corresponding threaded bore 235 of the other threaded screw, however, has at its length behind the thread 234 a short stem 236 formed without thread to which the projection 224 is connected by an external thread 228. This is dimensioned so that it can despite its outer η

thread 228 of the threaded threaded hole and passing through the corresponding hole 38A of the next part 22 6. In this case, the sleeve 22 0 with the sleeve 222 screwed on to the other part 226 is fed in front through the profile of the screwdriver in the notch 31 by rotating the threaded sleeve 2 so that its front side 230 with the front wall 16 of the profile piece 10 lies flat and the bearing surface 225 formed by the circumferential collar 23 abuts the inner wall 11 (cf., for example, FIG. 3). Also, in this case, the sleeve cannot fall into the interior of the profile because it is retained by the external thread 13 in the front wall 16 of the profile part 10 and in the partition wall 37.

Accordingly, the fitting part 4 (cf., for example, FIG. 3) is fitted and the screw 226 is screwed through the fitting part 4 into the threaded bore 235 of the other threaded part 226 until tight. At the same time, the threaded portion 224 is screwed through the openings 38 C, D of the hollow profile or into the metal fittings 14.

In another embodiment of the housing 301 of the invention, as shown in FIG. 7, which otherwise corresponds to that described in FIGS. 1 and 2, the outer thread 313 of the housing 301 has two sections 323, 324 of different diameters.

Contrary to the case. 11, in the housing 30, the first section 323 passes through its thread 313 only through the front wall 16 and the partition wall 37 and ends between the partition wall 37 of the profile 10 and the wall 11a of the hollow profile 7.

The second housing section 324 has a smaller diameter and corresponds substantially to the protrusion 24 of the housing 20 except that the thread 328 has the same direction of rotation as the thread 313. The second section 324 extends through the holes 38C, D and engages in the hollow profile 7 or its metal fitting 14.

The housing 301 is screwed into a slightly smaller groove 38 by means of a suitable tool engaging in the transverse cut 18 so that its front side 30 aligns with the front side 16 of the profile. The length of the sleeve is selected such that, when snapped in, it passes through all four openings 38 A, B, C, D lying in one line and also engages inside the metal fitting 14. The openings 38 C, D are adapted to the smaller diameter of the other a section 324 that is most suitably achieved using a stepped drill.

The bolt 306 may, in the embodiment shown in FIG. 7, be of the same length that is sufficient to introduce the forces to be transferred from the fitting part to the profile, but it must not be too long because the corresponding threaded hole in the housing 301 is not of the second section 324 no through hole.

Both the outer thread 313 and the outer thread 328 are adapted to the material combination of plastic and metal by their side shapes, so that the screw 306 can be screwed into a suitably adapted slightly smaller hole 38 in a self-cutting manner.

Another mold modification shown in FIG. At

323, 324 the modified through section 324 of a smaller diameter extends to a larger diameter. In the embodiment shown, the passage section 325 is formed by this arrangement, facilitating the fit of the profile housing.

The embodiment of FIG. 7 is in the form of sections of a section 325 in which the section 323 of the example is conical. 3 01 do
