Abstract

A profile element, in particular a building profile, for example a drywall, facade or plaster profile, is described with an in particular elongated metal base body, in which at least one opening is formed. The opening comprises at least one edge which is formed transversely to the longitudinal extent of the base body and is at least partially formed by a bent section of the base body. The bent section forms, together with an adjacent section of the base body, an at least double-layer region of the base body. In order to increase the rigidity of the profile element transversely to its longitudinal extent, the bent section is connected to the adjacent section within the at least double-layer region. Furthermore, a method for producing such a profile element is described.

Description

The present invention relates to a profile element, in particular a construction profile, for example, drywall, facade, plaster, screed or tile profile, with an in particular metallic or made of plastic elongate body in which at least one opening is formed. Furthermore, the invention is directed to a method for producing such a profile element.

Profile elements of this type are for example from the WO 2004/055289 A1 known and can be used in particular as a C-shaped stand profiles for drywall. To produce the profile elements of the elongated body is provided for example with a predetermined pattern. When selecting suitable patterns, two parallel longitudinal sections of the profile element can be pulled apart, in particular in a folding process, whereby a widening of the profile element takes place without additional material. The extended longitudinal sections are connected to each other via integrally formed with the longitudinal sections connecting elements. Corresponding patterns are in the WO 2004/055289 A1 whose contents, in particular with regard to the patterns described in this publication, are hereby explicitly included in the disclosure content of the present application.

Another possibility to produce expanded profile elements, is in the WO 2007/101594 A1 described. In this document, inter alia, a profile element is described, which is not generated by a folding process but by a pure expansion process, are widened in the profile introduced slots by drawing to diamond-shaped openings. Such a profile element can also be used in particular for the production of upright profiles. Also, the content of this document is hereby explicitly incorporated in the disclosure of the present application, in particular with regard to the patterns described in this document.

Furthermore, corresponding profile elements can also be produced without expansion or folding operation, so that the basic body, as is common, for example, in the case of normal upright profiles, has an unstretched, substantially closed construction. In such a body openings of the type mentioned can be introduced, for example, by a punching operation. The disadvantage of this is that the punched material forms rejects, whereby the manufacturing costs for such profile elements are increased.

In general, it is often desirable in profile elements of the type mentioned above and in particular for uprights that bushings are provided through which, for example, cables, wires or other elongated, band or cord-shaped elements and pipes or other hollow body can be passed. Regardless of whether such lead-through openings are produced by punching out corresponding holes in the base body, by the folding process described or by pulling apart, there is the problem that the profile element in the region of the opening produced, in particular in a direction transverse to the longitudinal extent of the profile element has a reduced rigidity ,

It is an object of the present invention to provide a profile element of the type mentioned, in which the rigidity in the region of the opening is increased compared to conventional profile elements.

Based on a profile element of the type mentioned, this object is achieved in that the opening comprises at least one edge formed transversely to the longitudinal extent of the body, which is at least partially formed by a bent portion of the body, that the bent portion together with an adjacent portion of the base body forms an at least double-layered region of the basic body and that, in order to increase the rigidity of the profile element transversely to its longitudinal extension, the bent-over section is connected to the adjacent section within the at least double-layered region.

A method according to the invention for producing such a profile element is characterized in that slots for folding out a portion of the base body are introduced into the base body, that the portion for forming an opening in the base body along a bending line extending transversely to the longitudinal extent of the base body, connecting the slots is folded out and bent until the bent portion together with an adjacent portion of the body forms an at least double-layered region of the body, and that is connected to increase the stiffness of the profile element transversely to the longitudinal extent of the bent portion within the at least double-layered portion with the adjacent portion ,

According to the invention, the reduced rigidity caused by the opening is thus compensated for by virtue of the fact that, at least in the region of an edge of the opening extending transversely to the longitudinal direction of the profile element double-layered area is generated and the individual layers of this area are connected to each other, so that no displacement of the two layers against each other is possible. At least one of the layers is produced by a material section which, by folding out of the base body, forms at least one region of the opening. As a result, on the one hand, the material used to form the opening is not wasted, but is used to stiffen the base body. On the other hand, by folding out the section from the opening, it is automatically ensured that the stiffening effect is given directly in the area of the opening, ie in the area of the weak point created by the opening. The term "transverse" is understood to mean any direction that does not extend exclusively in the longitudinal direction of the profile element. In particular, the transverse edge may be rectilinear or curved, as long as it extends transversely to the longitudinal direction of the profile element at least in a partial region.

Furthermore, no supply of a separate part to increase the rigidity is required by the integral connection of the folded out of the main body portion. Due to the integral connection of the bent portion with the base body, the production of the stiffening region in the online process is possible even at very high speeds, such as significantly more than 100 m / min.

According to an advantageous embodiment of the invention, the edge extends at least partially substantially perpendicular to the longitudinal extent of the body. As a result, a uniform support edge is provided for through the opening to be led lines or the like. At the same time, the double-layered region also extends perpendicularly to the longitudinal extent of the main body, so that the increased rigidity is also optimally achieved in a direction perpendicular to the longitudinal extension of the main body.

According to a further preferred embodiment of the invention, the bent-over section is connected to the adjacent section by a pressure joining method such as clinching or crimping, by clamping, crimping, pressing, welding, screwing, gluing or riveting. The stronger the connection between the bent portion and the adjacent portion of the body, the greater the rigidity of the profile. In particular, a shearing movement between the layers of the multi-layer area should be prevented with the chosen connection method, so that, for example, a bulging of the profile element is prevented.

Advantageously, the edge is formed substantially over its entire length by the bent portion. This may be the case, for example, if the main body is not divided into two spaced-apart longitudinal sections by pulling apart or the folding process described above, but essentially forms a closed surface. In this case, after inserting corresponding slots in the base body, a section defined by this slot can be bent out of the base body, wherein the edge formed during bending of this section automatically extends over the entire length of the resulting opening. Since the edge is formed in this case over its entire length as a bent edge, it is ensured that the edge is not sharp-edged, but has a certain roundness. This ensures that lines passed through the opening can rest on the edge without the risk of damaging the cables.

According to a further advantageous embodiment of the invention, a first part of the edge is formed by the bent portion. Advantageously, adjoining the first part of the edge, a second part of the edge, which is formed by a non-bent portion of the base body. In particular, the non-bent portion may form at least a part of the adjacent portion of the base body. Preferably, the first part of the edge can be formed by a single-layer bent portion, which is followed by at least a second part of the edge, which is formed by a double-layer bent portion of the base body.

This training is particularly useful when the body is divided into two longitudinal sections that are pulled apart by the folding process described above. The resulting already by the folding process openings can be additionally increased by corresponding bent portions, which are formed by both the bent portions, for example, the first longitudinal portion of the body as well as non-bent portions of the second longitudinal portion merging parts of the edge. In this case, the bent-over section can form a double-layered region both with the first longitudinal section and with the second longitudinal section, wherein in both of these two-layered regions and in both double-layered regions the connection of the bent-over section to the respective adjacent sections can be established. to achieve increased rigidity.

Advantageously, in this embodiment, the main body comprises two from each other spaced longitudinal portions which are parallel to each other and at a plurality of connection points integrally formed with the longitudinal sections, the distance between the longitudinal sections each bridging connecting elements are interconnected, wherein the opening extends from one of the longitudinal sections over the distance to the other longitudinal section and the bent Section forms a distance between the longitudinal sections bridging portion of the edge.

According to a further advantageous embodiment of the invention, the opening comprises at least two correspondingly formed, in particular opposite edges. As a result, the desired improved rigidity and thus an overall higher rigidity of the profile element in the region of the opening are achieved on both opposite sides of the opening.

According to a further preferred embodiment of the invention, the profile element is designed as a C-profile, U-profile, L-profile, T-profile, H-profiles, hat profile or Z-profile. In principle, the profile element according to the invention can also be used for other suitable types of profiles.

According to a further advantageous embodiment of the invention, the edge is at least partially overlapped by a cover and in particular includes. This is particularly useful in a sharp-edged design of the edge, since in this case guided through the opening through lines do not rest on the sharp-edged edge, but on the cover this cross element. This ensures that no damage to the guided through the opening elements can arise. The cover elements can not only overlap the support edge, but advantageously also be designed so that the entire peripheral edge of the opening overlaps and in particular is encompassed.

Advantageously, the edge can be provided at least in regions with a bend, in particular a flanging. This can be done in particular as an alternative, but in principle in addition to the cover described. Also by a bend is achieved that, despite a possibly sharp-edged design of the edge, the support for guided through the opening lines is rounded. This in turn avoids damage to the elements passed through the opening.

While the opening, as already described, may advantageously be designed as a leadthrough opening, in particular for electrical lines, it is also possible in principle that the opening fulfills a function deviating therefrom. In particular, the opening, for example, as an air passage opening or as a passage opening for other materials such. B. insulating materials are used. Also in this case, a stiffening of the profile element is achieved by the inventive design.

Advantageously, a plurality of openings are provided, which are distributed in particular in the longitudinal direction of the base body. The openings can be present in particular at regular intervals. By arranging a plurality of openings, the flexible use of a profile element designed according to the invention in the passage of lines, cables or the like is further increased.

Further advantageous embodiments of the invention are specified in the subclaims.

1 shows an elongated, flat material portion 1 , which may consist for example of metal, plastic or other suitable materials for producing a profile element according to the invention.

The material section 1 includes an elongated body 2 comprising a longitudinally extending base portion 3 and two laterally to the base section 3 adjacent sections 4 includes, for generating thighs 5 ( 2 ) each along a dashed line 6 can be bent by 90 °, so that a in 2 shown stand profile 7 is produced. This can be outside edge areas 8th the sections 4 again opposite the thighs 5 Angled at 90 °, so in this way a C-shaped stand profile 7 to create.

In the base section 3 are several slots 9 . 10 formed, of which the slots 9 in the longitudinal direction of the body 2 and the slots 10 run perpendicular to it. The slots 9 . 10 can be generated for example by rotary die cutting, laser cutting or any other suitable cutting or punching process.

Two slots each 9 are represented by broken lines shown as dashed lines 11 connected along which sections 12 of the basic body 2 for the formation of openings 13 ( 2 ) can be bent over. Through the bent sections 12 are each according to 2 edge 14 the openings 13 generated transversely and in particular perpendicular to the longitudinal extent of the body 2 run. The bent sections 12 of the basic body 2 are according to 2 bent so far that they are flat on adjacent sections 15 of the basic body 2 come to the plant in 1 are shown as hatched areas. Along with the adjacent sections 15 form the bent sections 12 thus double-layered areas 16 of the basic body 2 , respectively, in the longitudinal direction of the main body 2 Seen, each directly to the openings 13 are located afterwards.

How out 2 can be seen further, for example, designed as riveting fasteners 17 provided with which the bent portions 12 stuck with the adjacent sections 15 are connected. By the connecting means 17 be relative movements between the bent portions 12 and the adjacent sections 15 prevents stiffening of the body 2 directly in the area of the openings 13 ie in the through the openings 13 in its stiffness weakened area is achieved. By virtue of this stiffening effect, it is possible, for example, to achieve, when used as a upright profile, a bending of the base section 3 at a lateral load of the legs 5 , as it can occur, for example, when screwing in screws when attaching a planking, is avoided.

The openings 13 can be used to carry out elements such as electrical cables 18 , be used. Because the edges 14 each through the bent portions 12 are formed, the edges are 14 not sharp-edged, but have a certain roundness. This will avoid damaging the insulation of the electrical wires 18 on the edges 14 rest.

3 shows a section of material 19 with a basic body 35 which is a plurality of obliquely and along the longitudinal extent of the material section 19 running slots 20 having. Corresponding and modified patterns are in the WO 2004/055289 A1 described, the disclosure content of the different possible patterns and their use for expanding material sections is explicitly included in the present application.

In addition to these known patterns forming slots are in 3 on two slanted slits 21 subsequent slots 22 formed, which are transverse to the longitudinal extent of the material portion 19 run. At each of the slots 22 closes in the longitudinal direction of the material section 19 running slot 23 at, in turn, a parallel to the respective slot 22 extending another slot 24 followed. The ends of the two slots 24 are in turn by a longitudinal slot 25 connected with each other.

Approximately starting from the middle of the slot 25 another slot 26 again extends parallel to the slots 24 beyond their ends, wherein at the end of the slot 26 in turn two longitudinally extending slots 27 . 28 connect, each about the same height as the slots 24 end up. The ends of the slots 27 . 28 are with the slots 24 each with dashed lines 29 . 30 connected, the fold lines 31 . 32 represent as will be explained below.

Through the slots 24 . 25 . 26 . 27 and 28 become sections 33 . 34 of the basic body 35 bounded along the fold lines 31 . 32 can be bent, as will be explained in more detail below. In the sections 33 . 34 are each slit-shaped openings 36 formed in the longitudinal direction of the material portion 19 run.

Continue to be through the slots 22 . 23 and 24 tongue-shaped sections 37 . 38 of the basic body 35 formed, at the ends of tabs 39 . 40 are formed.

Through the slots 20 to 28 becomes the basic body 35 of the material section 19 in two longitudinal sections 41 . 42 split according to 4 transverse to the longitudinal extent of the material section 19 can be pulled apart and in the extended state over in one piece with the longitudinal sections 41 . 42 trained, the distance between the longitudinal sections 41 . 42 each bridging fasteners 43 connected to each other. Out 4 can be seen that by pulling apart and an additional bending of the sections 33 . 34 along the fold lines 29 . 30 between the longitudinal sections 41 . 42 an opening 44 arises in the longitudinal direction of the material section 19 through edges 45 . 46 is limited.

A first part 47 the edges 45 . 46 is in each case by the bent portions 33 . 34 formed while a subsequent second part 48 the edges 45 . 46 through the non-bent tongue-shaped sections 37 . 38 is formed. The bent sections 33 . 34 lie there, similar to the 1 and 2 described on adjacent sections 49 . 50 of the basic body 35 on, in 3 again shown as hatched areas. Other adjacent sections 51 . 52 be through the ends of the tongue-shaped sections 37 . 38 formed after bending over the sections 33 . 34 as well as the neighboring sections 49 . 50 , along with the bent sections 33 . 34 double-layered areas 53 . 54 of the basic body 35 form.

Within the double-layered areas 53 . 54 are the bent sections 33 . 34 each with the adjacent sections 49 to 52 via connecting means 55 . 56 firmly connected. The connecting means 55 are shown by way of example as riveted, but can also be designed as other suitable initially described connection means. The connecting means 56 are exemplary in 4 through the slit-shaped openings 36 as well as the tabs 39 . 40 the tongue-shaped sections 37 . 38 educated. These are the tabs 39 . 40 bent over and through the slit-shaped openings 36 stuck through it like that 4 is recognizable.

5 shows a C-shaped stand profile 57 made of a material section 35 according to the 3 and 4 is made. The stand profile 57 includes several openings 44 through which each electrical lines 18 or other supply lines can be performed. Because the edges 45 the openings 44 on which the electrical wires 18 abut, only in their in 5 right represented areas 58 by bending the section 34 is designed as a rounded edge, there is a risk that without additional protective measures passed through the electrical lines 18 Be damaged when on the rest of the edge 45 rest.

To avoid such damage, as shown in the upper opening 44 in 5 the rest of the edge 45 with a bend 63 be provided, for example, a flange.

Additionally or alternatively, according to the middle diagram in FIG 5 the edge 45 with a cover element 59 be provided. The cover element 59 For example, the in 6 have shown shape of a sleeve with longitudinal slot. The cover element 59 in this case, just on the edge 45 be plugged and either held by appropriate clamping action or additionally squeezed or pressed. Because the top of the cover 59 is formed rounded, damage to the electrical line in this way 18 prevented.

The cover may have different shapes and, for example, according to 7 to 9 as a hook-shaped cover 60 be educated. Through an extended, downwardly projecting section 61 of the cover 60 is an additional attachment of the cover 60 on the body 35 , For example, by riveting or other of the types of connection described above possible.

As in 5 shown in the lower area, the opening can be 44 also over its entire circumference by a corresponding cover 62 be covered. The cover element 62 thus forms a completely closed eyelet, which in a similar manner as the cover 59 respectively. 60 the edge 45 as well as the adjoining edges of the opening 44 covers.

Unlike the in 5 illustrated rectangular shape, the cover or the eyelet can also have rounded areas, so that ultimately a correspondingly rounded inner contour of the opening is achieved. In this way, for example, a circular, an elliptical, an oval or even an angular shape with rounded corners can be achieved. In this case, even the openings themselves may have a corresponding rounded shape. But it is also possible that the openings have a polygonal shape, as exemplified in 5 shown, own and a rounded inner contour only formed by appropriately trained cover elements or eyelets, the z. B. at the corners have a greater radial thickness than in the sections lying between the corners.

10 shows a further embodiment of the invention, in which the pattern after 3 modified. For simplicity, only the differences from the embodiment of FIGS 3 to 5 closer described. Same or similar elements are in the 10 to 13 with the same reference numerals as in the 3 to 5 Mistake.

In 10 close to the slots 21 each transverse to the longitudinal extent of the material section 19 running slots 64 on, each only up to the midline 65 of the material section 19 or up to the level of the middle of the oblique slots 20 . 21 formed cutting pattern in the upper and lower regions of the material section 19 extend. Thereby one of the slits runs 64 starting from one on one side of the midline 65 ending slot 21 and the other slot 64 starting from one on the other side of the midline 65 ending slot 21 towards the center line 65 ,

To the slots 64 closes one each along the center line 65 running slot 66 at, in turn, an opposite parallel to the respective slot 64 extending another slot 67 followed. At the ends of the slots 67 is in each case a perpendicular to the respective slot 67 running slot 68 formed, which are thus parallel to each other and parallel to the longitudinal extent of the material portion 19 extend. The centers of the two slots 68 are over a parallel to the slots 67 running slot 69 connected with each other. Furthermore, the slots extend 68 each over the slots 67 out and end in slanted slots 70 , which are shown by dashed lines 71 connected to each other. Similarly, the ends of the slots are also 67 dashed lines shown 72 with the slots 68 connected.

Corresponding to the slanted slits 70 are also in the area of joints between the slots 68 and 69 each slanted slots 73 formed by the between the slots 68 . 69 and 73 triangular holes 74 arise as it is in 10 can be seen. Both the slanted slots 70 as well as the slanted slots 73 are only optional and prevent that arise on the resulting profile element sharp corners. Therefore, these slots can basically be omitted. To avoid sharp corners, the slots could be 70 . 73 For example, be replaced by curved slots, so that ultimately rounded corners arise.

Between the slots 68 and 69 as well as the bend lines 72 are first sections 75 trained to be in between the fold lines 71 and 72 as well as the slots 68 and 70 bordered second sections 76 connect. Continue to be between the slots 66 . 67 . 68 and 70 as well as the bend lines 71 third sections 77 educated.

After introduction of the in 10 shown pattern, as already analogous to 4 described, the two longitudinal sections 41 . 42 of the basic body 35 pulled apart. This creates a distance between the longitudinal sections 41 . 42 passing through the fasteners 43 is bridged as it is in 11 is shown.

Subsequently, the sections 75 each along the fold lines 72 bent over, creating an in 12 illustrated opening 78 is produced.

In a further step, the already bent over sections 75 together with the sections that are now to be changed for the first time 76 and 77 along the fold lines 71 bent a second time, leaving the opening 78 gets its final size as it is in 13 is shown. The bent sections 75 . 76 . 77 form together with adjacent sections 79 . 80 (please refer 10 ) of the main body 35 double or triple layers 81 . 82 . 83 within which are the bent sections 75 . 76 . 77 with the neighboring sections 79 . 80 by connecting means 84 get connected. The connecting means 84 can be formed again in a variety of ways, as has already been described in detail in the context of this application.

In this embodiment, not only one part, but two parts each 85 . 86 the opening 78 in the longitudinal direction of the material portion bounding edges 87 . 88 directly through along the fold lines 71 when bending the sections 76 . 77 resulting creases formed so that these parts 85 . 86 are formed as rounded edges. Additional cover elements or eyelets for the edges 87 . 88 are therefore not essential. In principle, however, the cover elements and eyelets already described can also be used in this embodiment.
