Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a profile joining device, especially for aluminum lightweight structures.

[0002]

The problem underlying the present invention is to provide a profile joining device which is cost-effective and easy to assemble.

[0003]

This object is achieved in that two hollow profiles of the same rectangular cross section are formed, two hollow profiles of the same rectangular cross section are applied at a specific angle to one another and At least partly connected by two large-diameter pins of circular cross-section, these large-diameter pins, on the one hand, by means of a block fitted to the cross-section of the inner contour,
On the two inner contours of one hollow profile with these large-diameter pins projecting on the end face, on the other hand, on the one inner contour of the other hollow profile, which is penetrated through the hole in the wall by these large-diameter pins In the latter hollow profile, the blocks are held by small-diameter pins, and these small-diameter pins pass through the holes in the wall of the hollow profile to engage the holes of the block, and the cross-sections are aligned. Large pins that project into the notches in the block are held by the same small pins, these smaller pins extend further into the holes of the larger pins, or the tips are attached to these larger pins. The block and the large-diameter pin are held in the former hollow profile, or the large-diameter pin is pre-bonded to the block and the small-diameter pin engages the hole of the block or the tip of these blocks is tightened. Can be tightened to By the the go-between solution.

Only a total of 6 holes have to be drilled in both hollow profiles for the connection to take place. Of these holes, only the four smaller holes for the small diameter pins need to be accurately located. The two larger holes for the large diameter pins withstand larger tolerances. These holes do not determine the position of the large pin, but rather the two blocks on the inner contour. Large diameter pins are at least sufficiently round depending on the holes through which these large diameter pins pass. As a result, the block forms a transition from a round cross-section to a square cross-section, which square cross-section has an inner contour when the material cross-section of the hollow profile should not be enlarged due to increased costs. Alone due to the rectangular hollow profile for. These blocks fill the material cross section only where it is needed. These blocks can be moved very easily and precisely to this location, for example by means of a rod, which is pre-applied to the outside and brought to the required effective length by means of a movable and clampable stopper ring. . Since both blocks inserted into the same inner contour have the same constant distance from each other as both inner contours, these blocks are fixedly connected to each other. One contact is sufficient for this. In extreme cases, both blocks
It is also possible to continuously combine the structures having the same cross section. The laterally projecting large-diameter pin forms with the block two pipe pieces on which the end face of the other hollow profile can be placed directly. After mounting by means of the small-diameter pin, the coupling member is no longer visible at all, apart from the holes and the ends of the small-diameter pin which are covered by the glass sealing piece, which are not so important. Nevertheless, the bond is stable. This connection can also be carried out such that the large-diameter pin is first inserted into the abutting profile end.

However, a reverse tube piece laterally projecting from the other hollow profile as the attachment for the large-diameter pin is the preferred method. In particular for this purpose, it is preferred that the cross-section of the large-diameter pin is not continuously round, but is circular with at least one flat chamfer, preferably two opposite chamfers. As a result, the correct screwing position of the large-diameter pin is already ensured when the large-diameter pin is inserted through the hole of the profile wall into the block having the fitted notch, and at this screw-in position, the small-diameter pin is secured. The hole of the large pin provided for is aligned with the hole of the corresponding block or, if this large pin should be tightened only by the tip of the small pin, the other block shall be the hollow profile to which it strikes. It has the position required for insertion into the inner contour of the material. This block is preferably already connected to the large pin at the time of prefabrication. The large diameter pin and block are preferably manufactured as an integrally formed casting part, preferably of cast steel, having a large diameter pin hole and a threaded block hole. The small diameter pin is a screw.

The small diameter pins are preferably screws, which have mating threads on the profile walls or blocks or the large diameter pins. Because of the screws whose tips are to be fastened to the large diameter pins, these large diameter pins are preferably made of aluminum so that the tips can be pushed in slightly.

With respect to the inner contours, an advantageous construction of the invention is that these inner contours use, as is known, a connecting part which forms a threaded groove and a polygonal side of the profile section which follows this connecting part. It is proposed to be formed. Little additional material is needed.

It suffices for the inner contour to be completed only by the fins projecting from one another at the connection and the wall and to be open between these fins.

Finally, as a constitution advantageous for holding the present invention,
Shallow grooves are formed on both sides of the connecting part, and the width of this groove is the same as the width of the large-diameter pin between the chamfers facing each other, and these large-diameter pins pass through the block here. So as to engage with the groove. As a result, additional holding is provided for the large-diameter pin, and in addition material savings are achieved.

[0011]

[Exemplary Examples] The drawings show an embodiment of the present invention.

The hollow profile 1 is applied laterally to the hollow profile 2.

Both hollow profiles 1 and 2 have the same rectangular cross section. A threaded groove 4 is formed in one of the narrow walls 3, into which the screw is screwed in and the sealing piece is also mounted in this threaded groove, mainly for mounting the window glass. obtain. A connecting part 5 extends into the hollow cross section to form a threaded groove 4. Two fins 6 are provided at the end of this connecting part 5, and two fins 9 are provided facing the walls 7 and 8 of the hollow profile.

In this way, two inner contours 10 and 11 have been formed, into which the blocks 12 and 13 of combined square cross section can be inserted. The block makes full contact with the face of the walls 3 and 7 or 8 in the inner contour. The connecting part 5 contacts the block only on the two edge strips 14 and 15 on its connecting side. Between these edge strips the connection has a notch 16 of flat rectangular cross section. On the open side between the fins 6 and 9, contact is limited to the fins 6 and 9.

The two dice-shaped blocks 12, which are considered to be connected by a connecting part, are pushed into the connecting point by means of a rod in the inner contour 11 of the hollow profile 2.
The wall 8 is pre-drilled with two holes through which two round but opposite flat chamfers 18 are provided.
Two large-diameter pins 17 having a cross section having a cross section of are inserted into the notches 19 having the same cross section of the block 12, and further inserted into the notches 16 having the same width as the width of the large pin 17 between the chamfered portions 18. . Furthermore, two holes are bored in the wall 3, and the block 12 has a hole 20 and the large-diameter pin 17 to be inserted has a hole 21 in line with these holes. Small-diameter pins 22 are driven into the straight holes, and these small-diameter pins thereby insert the block 12 into the hollow profile 2
And a large pin 17 in the block 12, respectively.

The large-diameter pins 17 are fastened or pre-fastened to the blocks 13 having the notches 23 having the same cross section as those of the large-diameter pins 17, and the straight holes in the large-diameter pins 17 and the blocks 12 are aligned with each other. 24 or 25 is pinned by the aligned bores of a small diameter pin 26 which is driven and sinked. The two larger holes 27 or 28 in the large-diameter pin 17 and the block 13 are then aligned with each other.

If the inner contours 10 and 11 of the hollow profile 1 are fitted onto the block 13 until they hit the wall 8 of the hollow profile 2, the two holes 29 provided in the wall 3 of the hollow profile 1 are It comes to a position corresponding to these holes 27 or 28. It is thus possible to fix it by means of a screw 30 which is screwed through the holes 29 and 28 into the threaded hole 27. This connection between the large-diameter pin 17 and the hollow profile 1 can also be carried out first.

This embodiment is mainly used for explaining the principle, and is not a special structure in all the details.

The connection can also be made at an angle different from 90 ° by means of diagonally cut blocks 12 (eg from a slightly longer block 13).
