Description

The Invention relates to a section connector with two substantially flat legs, each for sliding in the longitudinal direction of a section into a channel of the section in a substantially fitting Is suitable, the legs being provided with locking means, which in connection with antidotes that are separate from them, serve to fix the leg in the channel of the respective section.

On such section connector is in shape in practice a corner element known. Each leg of the known section connector includes one or more protrusions extending from a major surface of the Go out legs. A vertical channel wall along the section which one leg of the connecting element is pushed has for everyone Projection an opening to let a screw penetrate at a point which the lead just while of the insertion process. While connecting sections through a fastener at a construction site after a leg has been pushed into a section channel, a screw through the opening screwed adjacent to a protrusion of the leg, thereby preventing that the leg slips back out of the section channel.

The known section connecting element has the disadvantage that it is necessary to drill holes in the sections beforehand exactly certain points for the above mentioned Drilling screws. In itself, this is a difficult and difficult one Cost-increasing Process, but it is complicated by the fact that the canal wall, into which the holes have to be drilled, a small dimension and often has a portion of an edge portion of the portion forms, which is narrow and has a complicated cross section, which makes drilling difficult.

On another disadvantage of the known connecting element is that an outermost position of the element relative to the connected sections of deviations in the position of the screw openings and depending on the type in which a fitter turns the screws into the openings, d. H. straight or oblique, so that the element is not a predetermined fixed location relative to the sections. This means that the sections may be incorrectly connected relative to each other and columns between their connected Ends become visible. This is a major aesthetic disadvantage, especially if the known connecting element is used in inner walls. The inaccurate Positioning can also mean other parts of a wall, of which the sections part, such as doors and glass panels, is difficult are to be positioned and cannot be positioned correctly.

On another disadvantage of the known connecting element is that heads the above Screws used to fix or retain the fastener used, often remain visible, which is even the case after a wall built with it is finished, and columns between elements on either side of the screw head. This in turn represents a great aesthetic Disadvantage.

Yet Another disadvantage of the known connecting element is that the screws already mentioned often used to set the element from one side of a section combination have to be screwed in such as the outside a door frame, which is difficult to reach at a construction site, and that before the section combination on a wall The floor of the construction site must be assembled, which must be clean must to prevent damage to the sections. such Working conditions can cannot always be reached at a construction site and do the assembly of section combinations difficult.

Other Known fasteners include in addition to the fastener various other types of separate fixing means, which one certain preparatory work on the sections or may require the use of special tools at the location or also not to fix a leg in a section channel to allow. These known connecting elements are therefore also difficult and expensive to use.

The The object of the invention is to overcome the disadvantages mentioned above remove.

To this end, the section connector of the type mentioned in the preamble according to the invention is characterized in that an initial section of each leg originating from the initial section of the other leg has a width greater than a channel edge distance between edges of a respective one U-shaped channel of the section, which are bent towards each other, in which channel the leg is pushed, an end section of the leg having a width which is smaller than the channel edge distance, and with an intermediate section between the start section and the end section has a width which is approximately equal to the channel edge distance, such that after the leg has been inserted into the channel, this in the intermediate can section bent over and edges of a bending area of the intermediate section grip the channel edges.

As Must follow by the connecting element according to the invention Sections to be connected are not processed beforehand, whereby the assembly of section combinations through the simple Bending process quickly and independently of the positions of the sections on the floor or otherwise can and section positioning errors due to human error while assembling the section combination are extremely rare.

The Section connector according to the invention is preferably characterized in that at a point where the legs meet, a tooth is formed such that after a Leg has been pushed into a channel of the section, the tooth against, but at most over the thickness runs along one wall of the canal. The tooth forms a stop, which is the displacement of a leg into a section canal or pulling the leg further into the Channel during limited the bending of its end portion. Especially when sections need to be connected with an angle where a material thickness the sections decrease towards the corner this that the sections are correctly positioned relative to each other and establish that there is no gap between the ends of the sections remains visible and that corners of the section ends securely against each other issue.

Other Features and advantages of the invention will be apparent from the following description exemplary embodiments the section connecting element according to the invention will be clear. The drawings show:

1 a front view of a first embodiment of a section connector according to the invention;

2 a side view of an end portion of the connecting element of FIG 1 ;

3 a cross-section of a section, which according to for use in combination with the connecting element 1 suitable is;

4 part of the section of 3 on an enlarged scale;

5 in perspective a combination of three sections, according to four connecting elements 1 are to be connected;

6 a perspective view of a second embodiment of a section connecting element according to the invention; and

7 a front view of a third embodiment of a section connecting element according to the invention.

This in 1 Section connector shown 1 according to the invention comprises two legs 2 which according to 1 are identical, but do not have to be identical.

Every leg 2 includes an initial section or root section 4 , an end section 5 and an intermediate section 6 , The legs 2 are essentially flat, have a common major surface and go in a common area 7 of the end sections 4 into each other.

The end section 5 from each leg 2 includes a reinforcement bar 11 which is in the longitudinal direction of the leg 2 runs and which a deformation of the end portion 5 prevented. The free end 12 of the end section 5 from each leg 2 is towards the side with the reinforcement bar 11 bent so that this while using the fastener 1 can be easily gripped with a finger.

The intermediate area 6 is relative to the rest of the leg 2 so weakened that when the leg 2 by keeping the common area 7 and the free end 12 is bent, the leg 2 in the intermediate area 6 will bend. As shown, the weakening can be through a series of two or more perforations 14 be formed that are transverse to the leg. Instead of two or more perforations 14 a single, preferably elongated perforation or a notch can be used.

3 shows a cross section of a section 20 in which the connecting element 1 according to 1 can be used. The section 20 has two channels 21 on which of the in 3 right channel 21 in 4 is shown on a larger scale. The channel is U-shaped and includes a bottom 22 , vertical walls from the floor 23 going out, and margins or marginal portions 24 who face each other.

The beginning section 4 from each leg 2 the connecting element of 1 has a width 31 on that is almost equal to a distance 32 between the vertical walls 23 of the channel 21 of the section 20 is. The thickness of the beginning section 4 of the leg 2 of the connecting element 1 is almost equal to the height of the vertical walls 23 , As a result, the leg can 2 of the connecting element ments 1 just in the channel 21 be pushed.

A width 34 of the end section 5 from each leg 2 the connecting element is smaller than a distance 35 between the ends of the edge sections 24 of the section channel 21 ,

5 shows three sections 20a . 20b . 20c the ends of which are chamfered at an angle of 45 °. The sections 20a . 20b . 20c form a door frame, for example, after they are connected together.

The sections 20a . 20b . 20c are through four connecting elements 1 according to 1 connected. Having a leg 2 a connecting element 1 as far as possible in a channel, for example 21a from section 20b has been pushed, the end section 5 of the leg 2 in the direction of the arrow 40 with the result that the leg moves 2 in the intermediate area 6 bends. In this process material of the intermediate section goes 6 sideways outwards with the result that the intermediate section 6 the edge sections 24 of the channel 21a grips firmly and the leg 2 is prevented from returning from the channel 21a to slide. The end section 5 can be bent up to 180 ° so that it is finally in a substantially flat position against the initial section 4 of the leg 2 comes to the plant and consequently does not form an obstacle for the components, such as lines and cables, in the remaining area of the section 20 a wall structure, of which the section combinations 20a . 20b . 20c form a part. This condition is left in 5 for the connected ends of the sections 20b and 20c illustrated.

After the end sections 5 of the legs 2 of two opposite connecting elements 1 , such as the connector 1 on the top right in 5 , the other legs can be bent up to 180 ° 2 of these fasteners 1 simply into the corresponding section channels 21 another section, section 20a in this example. The end sections 5 of the legs 2 can then be bent up to 180 ° so that the desired connection can be reached quickly and easily at a construction site.

The intermediate area 6 preferably has a width 42 on that a little bit, for example 1 mm, larger than the distance 35 between the ends of the edge sections 24 of the section channel, and the width gradually increases from the width 34 of the end section 5 of the leg 2 to the width 42 of the intermediate section 6 about. If in the case of this embodiment of the connecting element 1 the end section 5 one in a section channel 21 pushed leg 2 is bent, the leg 2 firmly in the channel 21 drawn and the edges of the intermediate area 6 and the edge section 24 of the section channel 21 are securely engaged with each other. A shape-preserving section combination, such as the combination 20a . 20b . 20c can be obtained in this way in a simple and quick manner.

It is for a tooth 45 preferable that this at the beginning of the opening section 4 from each leg 2 of the connecting element 2 is formed, in other words, at the area from the end 12 of the leg is farthest away, with the tip of this tooth over a distance 46 , for example 0.8 mm, over an adjacent edge of the initial section 4 of the leg 2 protrudes out. While pushing a leg 2 of the connecting element 1 into a section channel 21 or the pulling of the leg caused by the bending effect forms the tooth 45 a stop, which in the exemplary application shown, in the case of the vertical walls 23 of the channel 21 on the cut surface of the section 20 comes to the plant in 3 and 4 the plane of the drawing, and the fastener 1 at a precisely predetermined position relative to the two sections to be connected 20 fixed. Because the distance 46 is relatively small, preferably less than the thickness of the section in the case of the opposite vertical wall 23 of the channel 21 , the tooth is in the assembled section combination, for example 20a . 20b . 20c , not visible from the outside.

The sections are often made of extruded aluminum, while a tapered end of a section extends in thickness towards the tooth 45 reduced. That means the tooth 45 into the material of the two sections to be joined 20 can penetrate and set itself in it, so the distances 46 be aligned and an accurate positioning of the sections relative to each other is obtained in such a way that their projections and edges come to rest against each other exactly.

If the tooth 45 into the material of a section 20 penetrates, the material of the section must have a way out. To ensure that this material is not in the gap between the two sections to be joined 20 is a recess or a ridge 48 on each side of the tooth 45 formed in which recess the above-mentioned material of the sections 20 can find a way out.

Although the section connector according to the invention explained above takes the form of a right-angled corner member or right-angled Ab has angle, the angle between the legs 2 of any size. The angle can even be 180 °, as through the straight connecting element 51 of 6 is shown. As shown, such a straight element 51 with a tooth 45 and recesses 48 be provided, which lie opposite each other at the two longitudinal edges.

In addition, the invention can be applied to a section connection element in the form of a corner element, such as that in FIG 7 shown connecting element 53 , are used in which the main surfaces of the legs 2 intersect each other. Such a horizontal corner element 53 can be done by bending the legs 2 of the connecting element 51 of 6 towards each other in the area of the tooth 45 and by bending the tooth 45 towards the inside of the through the legs 2 formed angle can be obtained.
