Description

The invention relates to a profile insert for a hollow frame profile and Process for connecting hollow frame profiles together.

Hollow frame profiles are mainly used in door, window and facade construction used to place panes or plates between frame profiles to keep. These hollow frame profiles are often made of plastic. To the To increase the strength of such hollow plastic frame profiles is in a Chamber of the profile arranged a steel profile insert, the for example, as a rectangular tube, the desired hollow frame profile Gives stability. The profile insert also allows fittings to be fastened by means of screws that pass through the wall of the Hollow frame profile penetrate into the profile insert and thus stronger are resilient.

However, it has been shown that especially when attaching door or window sashes the resilience of the hollow frame profile despite the profile use is unsatisfactory. This problem is addressed in the prior art through thicker profile inserts or the use of several screws solved.  

The invention has for its object to provide a hollow frame profile a profile insert so that a stable attachment strong stressed fittings is facilitated.

This object is achieved in that the profile insert has a guide channel for a screw screwed into the hollow frame profile.

While usual steel reinforcements only in the thickness range Steel reinforcement in connection with the screwed screw, the guide channel allows an engagement between screw and profile use over a larger area and thus increases the stability of the screwed screw.

To one in the longitudinal direction of the profile insert at any point Providing guide channel, it is proposed that the guide channel is formed in a gap. This enables easy manufacture of the Profile insert, which is preferably the same over the entire length Has cross section.

In addition, it is proposed that the guide channel be conical forms is. This makes it easier to position the screw in the guide channel and optimizes the contact surface between the guide channel and Screw.

A simple embodiment of the profile insert provides that the Profile insert is essentially rectangular. This allows the insertion of the  Profile insert in commercially available hollow frame profiles and allows one sufficient stiffening of the hollow frame profile.

It is advantageous if the guide channel is in the area of a right-angled one Corner of the profile insert is arranged. Especially when it comes to fastening of hinges for doors becomes optical and constructive For reasons, make sure that the tape as close to the side of the Door frame and the door leaf is attached. This leads to a asymmetrical arrangement of the guide channel on the profile insert, whereby the position of the guide channel on the hinge used is to be coordinated.

Especially with the arrangement of the guide channel described above Area of a right-angled corner of the profile insert, it is advantageous if the guide channel is parallel to a side wall of the profile insert runs.

Depending on the field of application of the profile insert, it can be advantageous if the guide channel is U-shaped. On the one hand, this allows a blind hole-like channel into which the screw is screwed. On the other hand, access to the canal can also be through part of the Profile insert be covered so that this part is pierced first must so that the screw can then penetrate into the guide channel can. The pierced part of the profile insert offers the screw additional hold.  

Understandably, the profile insert can also have several guide channels exhibit. These guide channels can be attached on the one hand different screws and on the other hand they can serve to strengthen the profile insert.

Especially with inserts formed from a sheet, thinner sheet can be used strengths are used, provided that the static requirements are met repeated folding of the sheet onto each other or to form channels is sufficient.

However, the profile insert can also be made from aluminum. It is advantageous if the profile insert is designed so that it can be manufactured as an extruded profile. This enables a very individual Design of the shape of the profile insert and thus facilitates Attachment of screw channels.

In addition, an individual adaptation of the profile insert to the Inner contour of a hollow frame profile is advantageous to the outer surfaces the profile insert as far as possible from the center. This increases stability with the same amount of material.

This can be done by special folding of steel reinforcements or the Shape of an aluminum profile can be achieved.

In particular, the exemplary embodiments described below show that the guide channel also as a bore in an at least two layers  laid sheet metal part or a thickening in an aluminum part can be formed.

It is advantageous if the profile insert on its inner wall has arranged webs. These bridges allow one Corner connector to cooperate, which grooves or in the area of the webs Has cutouts and by the webs against twisting is secured.

To counteract twisting as well as possible suggested that the webs to the center of the cross section of the profile insert are directed. These webs pointing radially inwards are particularly good suitable to hold a corner connector.

In practice, a corner connector is then arranged in the profile insert. This Corner connector serves two profile inserts and therefore two To connect hollow frame profiles in the corner area. The However, corner connectors do not necessarily have to have an angle of 900, but it can be carried out at any angle. In extreme cases the corner connector has an angle of 1800 and thus serves as an extension.

So that the corner connector with the profile insert is form-fitting can cooperate, it is proposed that the outer contour of the Corner connector essentially on the inner contour of the profile insert is coordinated.  

Good results are achieved if the outer contour of the corner connector is essentially star-shaped.

To give the corner connector the necessary stability suggested that in the corner connector diagonal reinforcing webs are arranged. The grooves in the corner connector are preferably after one Tapered towards, so that the corner connector in addition to the positive connection a positive connection by driving into the profile insert comes in.

A preferred embodiment provides that the outer contour of the Corner connector is dovetail-shaped in cross section. This also allows a simple interaction with a radial after internally projecting web structure of the profile insert.

The invention also leads to a method for connecting Hollow chamber profiles with each other, which is characterized in that Profile inserts with different outer contours and the same Inner contours are produced.

To connect different hollow chamber profiles with each other, had to So far, various corner connectors have also been used. The Profile insert according to the invention allows different external dimensions to fit in different hollow chamber profiles. The However, internal dimensions that interact with a corner connector can  be designed precisely so that a wide variety of profile inserts with the same corner connector can work together.

Embodiments of hinge systems according to the invention with a Profile insert and different profile inserts are in the drawing are shown and are explained in more detail below.

Fig. 1 shows two hollow frame profiles 1 and 2 which are connected by a hinge band 3 . The hollow frame profile 1 consists of a hollow profile 4 made of plastic, which has a substantially rectangular chamber 5 . In this chamber 5 a substantially rectangular reinforcement profile is arranged as a profile insert 6 . In the present case, this hollow frame profile 1 serves as a frame spar of a door.

The via the hinge 3 to the frame beam 1 attached hollow frame profile 2 is used as a frame of a door leaf (not shown). This hollow frame profile 2 also has a plastic profile part 7 , in which a hollow chamber 8 is provided. This hollow chamber 8 has a special inner contour, which is fissured by elements protruding into the chamber 8 , such as 9 , 10 . In this chamber 8 , an extruded profile 11 made of aluminum is used, the outer contour of which is adapted to the fissured inner wall of the hollow frame profile made of plastic. The profile insert 11 is thus held firmly in the hollow frame profile part 7 .

The hinge band 3 consists of a fixed part 12 and an arm 14 articulated thereto by a bolt 13 , both of which are connected to each of the hollow frame profile parts by means of screws and bolts 15 , 16 , 17 , 18 .

The arranged in the door frame profile insert 6 consists of a ge bent sheet steel, which is bent in the region of the bolts 15 and 16 so that two opposite surfaces 19 and 20 or 21 and 22 abut on the bolts 15 and 16 . A guide channel 23 or 24 is thus formed between these surfaces.

The profile insert 11 arranged in the other hollow frame profile part 2 has two parallel webs 26 and 27 in the area of a corner 25 of the profile insert 11 , which form a guide channel 28 for the screw 18 between them.

Fig. 2 shows a similar device of two hollow frame profiles 31 and 32 , which are connected to one another via a hinge strap 33 . Screws or bolts 34 , 35 , 36 , 37 serve as connecting elements, of which elements 34 and 37 are connected to profile inserts 38 and 39 , respectively.

In this embodiment, an extruded aluminum profile is provided as a profile insert 38 in the hollow frame profile 31 of the door frame, and this profile insert has two webs 40 and 41 arranged next to one another, between which a guide channel 42 is formed. This guide channel 42 gives the bolt 34 sufficient hold to permanently attach it to the hollow frame profile 31 . The outside of the profile insert 38 is in turn adapted to the jagged inner wall 43 of the plastic profile part 44 .

The frame profile part 32 of the door leaf (not shown) consists of an essentially rectangularly curved shape of a steel sheet, the ends of which are bent inwards as two webs 45 , 46 . These opposing webs 45 and 46 form a guide channel 47 between them, in which the screw 37 is adequately held.

The guide channels shown in the drawing are parallel Drawn walls. However, the walls can also be in one acute angles to each other, so that a conical Guide channel is created.

The extruded profile insert made of aluminum can be used in many different ways Shapes. This means that several screw channels can also be used can be arranged side by side or additional webs to increase the Stability of the profile insert or to facilitate the attachment of others Fittings can be provided. Instead of a pre-formed channel a piece of solid material may also be provided, which is only after introduction a hole becomes a guide channel.

Profile inserts bent from a metal sheet such as preferably a steel sheet can also have different shapes, which are optimally adapted to the task depending on the area of use. Various embodiments Fig. 3 shows.

In Fig. 3a, a U-shaped guide channel 50 with an open screw-in end 51 is provided. In order to give the screw to be screwed in also in the longitudinal direction of the profile insert, a covered guide channel 52 is shown in FIG. 3b, which is only accessible to the screw when a hole is provided in the cover 53 .

Fig. 3c shows that even a hole by a plurality of superimposed ends 54, 55 of a profiled insert can form a guide channel. As shown in FIG. 3d, this guide channel can be lengthened and thus reinforced by several surfaces of a steel profile end placed in parallel.

In order to improve the introduction of holes and the fastening of screws in a wider area, it is proposed, as shown in FIG. 3e, to place a steel sheet several times at least over a large proportion of one side of the profile insert.

Fig. 3f shows the ultimately Kombinafion of a guide channel between two ends 56, 57 of a steel plate with a double-layer sheet metal section 58 in which a bore 59 is provided.

FIG. 4 shows a development of a tread insert 60. The external dimensions of this profile insert are matched to a hollow chamber profile 2 , as shown for example in FIG. 1. In the profile insert webs 61 and 62 are provided which form a guide channel 63 for a screw (not shown). In this case, however, the cavity 64 enclosed by the profile part serves to accommodate a corner connector 65 (see FIG. 5) and is therefore provided with webs 66 , 67 , 68 and 69 pointing radially inwards. These webs 66 to 69 cooperate with grooves 70 to 73 in the corner connector 65 , so that a positive connection between the corner connector 65 and the profile part 60 is created. The grooves 70 to 73 are tapered in one direction such that when the corner connector 65 is driven into the profile insert 60 , a non-positive connection is also created between the profile insert 60 and the corner connector 65 .

The profile insert 80 shown in FIG. 6 has an outer contour that corresponds to the outer contour of the profile insert shown in FIG. 4. The inner contour is matched to a corner connector 81 with a dovetail-shaped outer contour, so that the corner connector 81 interacts positively with the profile part 80 . The corner connector 81 also has diagonal reinforcing struts 82 and 83 in order to increase the stability of the corner connector and to ensure the necessary strength, in particular when the corner connector is turned in, for a positive connection.

The profile inserts shown in FIGS. 4 and 6 each have a further screw channel 75 or 76 , which is aligned with a fitting groove designated by the reference number 77 in FIG. 1. The screw channel thus makes it possible to fasten fittings arranged in the fitting groove 77 to the profile insert by means of screws.

The embodiments of Fig . 4 to 7 show that the profile inserts are manufactured with a wide variety of external dimensions and that the internal dimensions can be matched to a special type of corner connector. This means that a wide variety of hollow frame profiles can be reinforced with profile inserts tailored to the respective type of hollow frame profile, while only one type of corner connector is used for the different profile inserts.
