Definitions
- the present invention relates to a section element, in particular to a structural section, for example a dry construction section, a facade section, a plaster section, a screed section or a tile section, having an elongated base body, in particular comprising metal or plastic, in which at least one opening is formed.
- the invention is furthermore directed to a method of manufacturing such a section element.
- Section elements of this kind are known, for example, from WO 2004/055289 A1 and can in particular be used as C-shaped upright sections for dry construction.
- the elongated base body is provided with a predefined cutting pattern, for example, for manufacturing the section elements.
- a predefined cutting pattern for example, for manufacturing the section elements.
- two longitudinal portions of the section element which extend in parallel can in particular be drawn apart in a folding process, whereby a widening of the section element takes place without additional material input.
- the drawn apart longitudinal sections are in this respect connected to one another via connection elements formed integrally with the longitudinal portions.
- Corresponding cutting patterns are described in WO 2004/055289 A1 whose content, in particular relating to the cutting patterns described in this document, is herewith explicitly included in the disclosure content of the present application.
- WO 2007/101594 A1 A further possibility of producing widened section elements is described in WO 2007/101594 A1.
- a section element is inter alia described which is not produced by a folding process, but rather by a purely widening process, in which slits introduced into the section are widened by drawing up to diamond-shaped openings.
- Such a section element can also in particular be used for manufacturing upright sections.
- the content of this document, in particular relating to the cutting patterns described in this document, is also herewith explicitly included in the disclosure content of the present application.
- Corresponding section elements can furthermore also be manufactured without a widening procedure or folding procedure so that the base body, as is, for example, usual with normal upright sections, has a non-elongated, substantially closed design. Openings of the initially named kind can be introduced into such a base body, for example by a punching process. It is disadvantageous in this that the punched out material forms waste, whereby the manufacturing costs for such section elements are increased.
- section elements of the initially named kind and in particular with upright sections, that leadthrough openings are provided through which, for example, cables, lines or other elongated band-like or cord-like elements as well as pipes or other hollow bodies can be led.
- leadthrough openings are produced by punching out corresponding holes in the base body, by the described folding process or by drawing apart, there is the problem that the section element has a reduced stiffness in the region of the produced opening, in particular in a direction transverse to the longitudinal extent of the section element.
- the opening includes at least one edge which is formed transversely to the longitudinal extent of the base body and which is formed at least partly by a bent over portion of the base body; in that the bent-over portion forms an at least double-layer region of the base body together with an adjacent portion of the base body; and in that the bent-over portion is connected to the adjacent portion within the at least double-layer region to increase the stiffness of the section element transversely to its longitudinal extent.
- a method designed in accordance with the invention of manufacturing such a section element is characterized in that slits are introduced into the base body for folding out a portion of the base body; in that the portion is folded out and bent over for forming an opening in the base body, along a kink line extending transversely to the longitudinal extent of the base body and connecting the slits, until the bent over portion forms an at least double-layer region of the base body together with an adjacent portion of the base body; and in that the bent over portion is connected to the adjacent portion within the at least double-layer region to increase the stiffness of the section element transversely to its longitudinal extent.
- the reduced stiffness caused by the opening is compensated in that an at least double-layer region is produced directly in the region of an edge of the opening extending transversely to the longitudinal direction of the section element and the individual layers of this region are connected to one another so that no displacement of the two layers toward one another is possible.
- At least one of the layers is produced by a material portion which forms at least one region of the opening by folding out of the base body. It is thereby achieved, on the one hand, that the material used for forming the opening is not wasted, but is rather used for stiffening the base body. On the other hand, it is automatically ensured by folding out the portion from the opening that the stiffening effect is present directly in the region of the opening, i.e.
- transverse is to be understood as any direction which does not extend only in the longitudinal direction of the section element.
- the transversely extending edge can in particular be formed as a straight line or curved as long as it extends transversely to the longitudinal direction of the section element at least in a part region.
- the edge extends at least regionally substantially perpendicular to the longitudinal extent of the base body.
- a uniform support edge for lines to be led through the opening or the like is thereby provided.
- the double layered region also extends perpendicular to the longitudinal extent of the base body so that the increased stiffness is also achieved in an ideal fashion in a direction perpendicular to the longitudinal extent of the base body.
- the bent over portion is connected to the adjacent portion by a pressure joining process such as clinching or crimping, by clamping, squeezing, pressing, welding, screwing, bonding or riveting.
- a pressure joining process such as clinching or crimping, by clamping, squeezing, pressing, welding, screwing, bonding or riveting.
- the edge is advantageously formed over its total length by the bent over portion. This can be the case, for example, when the base body is not divided into two spaced apart longitudinal portions by drawing apart or by the initially described folding process, but rather substantially forms a closed surface.
- a portion defined by these slits can be bent out of the base body, wherein the edge arising on the bending over of this portion automatically extends over the total length of the opening thereby arising. Since the edge is in this case formed as a kink edge over its total length, it is ensured that the edge is not formed as a sharp edge, but rather has a certain roundness. It is thereby achieved that lines led through the opening can lie on the edge without there being any risk of damage to the lines.
- a first part of the edge is formed by the bent over portion.
- a second part of the edge which is formed by a non-bent over portion of the base body, advantageously adjoins the first part of the edge.
- the non-bent over portion can in particular form at least a part of the adjacent portion of the base body.
- the first part of the edge can preferably be formed by a single-layer bent over portion which is adjoined by at least one second part of the edge which is formed by a double-layer bent over portion of the base body.
- This design is in particular sensible when the base body is divided into two longitudinal portions which are drawn apart by the initially described folding process.
- the openings already arising due to the folding process can additionally be enlarged by correspondingly bent over portions, whereby parts of the edge merging into one another are formed both by the bent over portions of the first longitudinal portion of the base body, for example, and by non-bent over portions of the second longitudinal portion.
- the bent over portion can in this case form a double-layer region both with the first longitudinal portion and with the second longitudinal portion, wherein the connection of the bent over portion to the respective adjacent portions can be established both in one of these double-layer regions and in both double-layer regions to achieve an increased stiffness.
- the base body advantageously includes two mutually spaced apart longitudinal portions which extend parallel to one another and are connected to one another at a plurality of connection points via connection elements formed in one piece with the longitudinal portions and in each case bridging the spacing between the longitudinal portions, wherein the opening extends from one of the longitudinal portions beyond the spacing to the other longitudinal portion and the bent over portion forms a region of the edge bridging the spacing between the longitudinal portions.
- the opening includes at least two correspondingly formed edges in particular disposed opposite one another.
- the desired improved stiffness is thereby achieved at both oppositely disposed sides of the opening and thus an even higher stiffness of the section element in the region of the opening overall.
- the section element is formed as a C section, a U section, an L section, a T section, H sections, a hat section or a Z section.
- the section element in accordance with the invention can generally also be used for other suitable section types.
- the edge is at least regionally engaged over and in particular encompassed by a cover element.
- a cover element This is in particular sensible with a sharp-edged design of the edge since in this case lines led through the opening do not lie on the edge formed with a sharp edge, but rather on the cover element engaging around it. It is thereby ensured that no damage can occur to the elements led through the opening.
- the cover elements can in this respect not only engage around the support edge, but advantageously also be formed so that the total peripheral edge of the opening is engaged over and in particular encompassed.
- the edge can advantageously be provided at least regionally with a bend, in particular a flange. This can in particular take place as an alternative; generally, also however, in addition to the described cover element. It is also achieved by a bend that the support for lines led through the opening is made rounded despite any formation of the edge as a sharp edge. Damage to the elements led through the opening is thereby in turn avoided.
- the opening can, as already described, advantageously be formed as a leadthrough opening, in particular for electrical lines, it is generally also possible that the opening satisfies a function different from this.
- the opening can in particular, for example, also be used as an air passage opening or as a passage opening for other materials such as insulating materials.
- a stiffening of the section element is also achieved by the design in accordance with the invention in this case.
- a plurality of openings are advantageously provided which are in particular arranged distributed in the longitudinal direction of the base body.
- the openings can in this respect in particular be present at regular intervals.
- the flexible use of a section element designed In accordance with the invention for the leading through of lines, cables or the like is further increased by the arrangement of a plurality of openings.

- FIG. 5 a further C section in accordance with the invention formed with the cutting pattern in accordance with FIG. 3 ;
- FIG. 6 a perspective representation of a cover element
- FIGS. 7 to 9 perspective representations of further cover elements.
- FIGS. 10 to 13 four different states during the manufacture of a further embodiment of the invention.
- FIG. 1 shows an elongated, flat material portion 1 , which can comprise, for example, metal, plastic or other suitable materials for manufacturing a section element in accordance with the invention.
- the material portion 1 includes an elongated base body 2 which includes a base portion 3 extending in the longitudinal direction as well as two portions 4 which are laterally adjacent to the base portion 3 and which can be bent over by 90° in each case along a dashed line 6 for producing limbs 5 ( FIG. 2 ) so that an upright section 7 shown in FIG. 2 is produced.
- outwardly disposed marginal regions 8 of the portions 4 can again be angled by 90° with respect to the limbs 5 to produce a C-shaped upright section 7 in this manner.
- a plurality of slits 9 , 10 are formed in the base portion 3 of which the slits 9 extend in the longitudinal direction of the base body 2 and the slits 10 extend perpendicular thereto.
- the slits 9 , 10 can in this respect be produced, for example, by rotary stamping, laser cutting or another suitable cutting or stamping process.
- Two respective slits 9 are connected by kink lines 11 which are shown as dashed lines and along which portions 12 of the base body 2 can be bent over for forming openings 13 ( FIG. 2 ).
- Edges 14 of the openings 13 are respectively produced by the bent over portions 12 in accordance with FIG. 2 and extend transversely, and in particular perpendicular, to the longitudinal extent of the base body 2 .
- the bent over portions 12 of the base body 2 are in this respect bent over so much in accordance with FIG. 2 that they come into areal contract at adjacent portions 15 of the base body 2 which are shown as hatched areas in FIG. 1 . Together with the adjacent portions 15 , the bent over portions 12 thus form double-layer regions 16 of the base body 2 which are disposed, viewed in each case in the longitudinal direction of the base body 2 , respectively directly adjoining the openings 13 .
- connection means 17 are provided which are, for example, formed as rivets, and with which the bent over portions 12 are fixedly connected to the adjacent portions 15 . Relative movements between the bent over portions 12 and the adjacent portions 15 are prevented by the connection means 17 , whereby a stiffening of the base body 2 is achieved directly in the region of the openings 13 , i.e. in the region weakened in its stiffness by the openings 13 . It can, for example, be achieved by this stiffening effect that, on the use as an upright section, a bending of the base portion 3 on a lateral load of the limbs 5 , such as can occur on the screwing in of screws on the attachment of planking, is avoided.
- the openings 13 can be used for leading through elements such as electrical lines 18 . Since the edges 14 are each formed by the bent over portions 12 , the edges 14 are not made as sharp edges, but rather have a certain rounding. It is thereby avoided that damage takes place to the insulation of the electrical lines 18 which lie on the edges 14 .
- FIG. 3 shows a material portion 19 with a base body 35 which has a plurality of slits 20 which extend obliquely and along the longitudinal extent of the material portion 19 .

- slits 22 are formed in FIG. 3 which adjoin two slits 21 extending obliquely and which extend transversely to the longitudinal extent of the material portion 19 .
- a slit 23 extending in the longitudinal direction of the material portion 19 adjoins each of the slits 22 and is in turn adjoined by a further slit 24 extending parallel to the respective slit 22 .
- the ends of the two slits 24 are in turn connected to one another by a slit 25 extending in the longitudinal direction.
- a further slit 26 in turn extends parallel to the slits 24 and beyond their ends, with in turn two slits 27 , 28 adjoining the end of the slit 26 which extend in the longitudinal direction and which each end approximately at the level of the slits 24 .
- the ends of the slits 27 , 28 are connected to the slits 24 in each case via dashed lines 29 , 30 which represent kink lines 31 , 32 such as will be set forth in the following.
- Portions 33 , 34 , of the base body 35 which can be bent over along the kink lines 31 , 32 , as will be explained in more detail in the following, are bounded by the slits 24 , 25 , 26 , 27 and 28 .
- Respective slit-shaped openings 36 are formed in the portions 33 , 34 and extend in the longitudinal direction of the material portion 19 .
- Tongue-like portions 37 , 38 of the base body 35 at whose ends tabs 39 , 40 are formed are furthermore formed by the slits 22 , 23 and 24 .
- the base body 35 of the material portion 19 is divided into two longitudinal portions 41 , 42 by the slits 20 to 28 , said longitudinal portions being able to be drawn apart transversely to the longitudinal extent of the material portion 19 in accordance with FIG. 4 and being connected to one another in the drawn apart state via connection elements 43 formed in one piece with the longitudinal portions 41 , 42 and respectively bridging the spacing between the longitudinal portions 41 , 42 .
- connection elements 43 formed in one piece with the longitudinal portions 41 , 42 and respectively bridging the spacing between the longitudinal portions 41 , 42 .
- an opening 44 which is bounded by edges 45 , 46 in the longitudinal direction of the material portion 19 is created between the longitudinal portions 41 , 42 by the drawing apart and by an additional bending over of the portions 33 , 34 along the kink lines 29 , 30 .
- a first part 47 of the edges 45 , 46 is in this respect in each case formed by the bent over portions 33 , 34 , whereas a second part 48 of the edges 45 , 46 adjoining it is formed by the non-bent over tongue-like portions 37 , 38 .
- the bent over portions 33 , 34 in this respect contact, in a similar manner to that described in FIGS. 1 and 2 , adjacent portions 49 , 50 of the base body 35 which are in turn shown as hatched regions in FIG. 3 .
- adjacent portions 51 , 52 are farmed by the ends of the tongue-like portions 37 , 38 which, after the bending over of the portions 33 , 34 , as also the adjacent portions 49 , 50 , form double-layer regions 53 , 54 of the base body 35 together with the bent over portions 33 , 34 .
- connection means 55 , 56 are respectively fixedly connected to the adjacent portions 49 to 52 via connection means 55 , 56 within the double-layer regions 53 , 54 .
- the connection means 55 are in this respect shown by way of example as rivet connections, but can also be formed as other suitable connection means already initially described.
- the connection means 56 are formed by way of example in FIG. 4 by the slit-shaped openings 36 and by the tabs 39 , 40 of the tongue-like portions 37 , 38 .
- the tabs 39 , 40 are bent over and pushed through the slit-shaped openings 36 , as can be recognized from FIG. 4 .
- FIG. 5 shows a C-shaped upright section 57 which is manufactured from a material portion 35 in accordance with FIGS. 3 and 4 .
- the upright section 57 includes a plurality of openings 44 through which respective electrical lines 18 or other supply lines can be led. Since the edges 45 of the openings 44 on which the electrical lines 18 lie are only formed as a rounded edge by bending over the portion 34 in their regions 58 shown at the right in FIG. 5 , there is a risk that the electrical lines 18 led through will be damaged without additional protective measures if they lie on the other region of the edge 45 .
- the remaining region of the edge 45 can be provided with a bend 63 , for example with a flange.
- the edge 45 can be provided with a cover element 59 .
- the cover element 59 can, for example, have the shape of a sleeve with a longitudinal slit shown in FIG. 6 .
- the cover element 59 can in this case be simply plugged onto the edge 45 and can either be held by a corresponding clamping effect or can additionally be squeezed or pressed. Since the upper side of the cover element 59 is made rounded, damage to the electrical line 18 is prevented in this manner.
- the cover element can have different shapes and can, for example, also be made as a hook-shaped cover element 60 in accordance with FIGS. 7 to 9 .
- an additional fastening of the cover element 60 to the base body 35 is possible by an extended downwardly projecting portion 61 of the cover element 60 , for example by riveting or by another of the initially described kinds of connection.
- the opening 44 can also be covered over its total periphery by a corresponding cover element 62 .
- the cover element 62 thus forms an eyelet which is closed all round and which covers the edge 45 as well as the edges of the opening 44 adjoining it in a similar manner to the cover elements 59 and 60 respectively.
- the cover element or the eyelet can also have rounded regions so that ultimately a correspondingly rounded inner contour of the opening is achieved.
- a circular, an elliptical, an oval or also an angular shape with rounded corners can be achieved, for example.
- the openings themselves can already have a corresponding rounded shape.
- the openings have an angular shape such as is shown by way of example in FIG. 5 and a rounded inner contour only arises by correspondingly formed cover element or eyelets which e.g. have a larger radial thickness at the corners than in the portions lying between the corners.
- FIG. 10 shows a further embodiment of the invention in which the cutting pattern in accordance with FIG. 3 is modified.
- the cutting pattern in accordance with FIG. 3 is modified.
- FIGS. 3 to 5 show the same or similar elements in this respect provided with the same reference numerals in FIGS. 10 to 13 as in FIGS. 3 to 5 .
- slits 64 adjoin the slits 21 and respectively extend transversely to the longitudinal extent of the material portion 19 and respectively extend only up to the center line 65 of the material portion 19 or up to the level of the center of the cutting patterns formed by the obliquely extending slits 20 , 21 in the upper and lower regions of the material portion 19 .
- one of the slits 64 extends starting from a slit 21 ending at one side of the middle line 65 and the other slit 64 extends starting from a slit 21 ending on the other side of the center line 65 in the direction toward the center line 65 .
- a respective slit 66 which runs along the center line 65 and which is in turn adjoined by a further slit 67 extending oppositely and parallel to the respective slit 64 adjoins the slits 64 .
- a respective slit 68 extending perpendicular to the respective slit 67 is formed at the ends of the slits 67 and thus extend parallel to one another and parallel to the longitudinal extent of the material portion 19 .
- the centers of the two slits 68 are connected to one another via a slit 69 extending parallel to the slits 67 .

Abstract
The invention relates to a profiled element, in particular a profiled construction element, for example a profiled dry construction, façade, or plaster element, comprising an in particular metal elongated main body, in which at least one opening is formed. The opening has at least one edge formed transversely to the longitudinal extension of the main body, which edge is formed at least partially by a bent-over section of the main body. The bent-over section, together with an adjacent section of the main body, forms an at least double-layer area of the main body. In order to increase the stiffness of the profiled element transversely to the longitudinal extension thereof, the bent-over section is connected to the adjacent section within the at least double-layer area. The invention further relates to a method for producing such a profiled element.
Description
- The present invention relates to a section element, in particular to a structural section, for example a dry construction section, a facade section, a plaster section, a screed section or a tile section, having an elongated base body, in particular comprising metal or plastic, in which at least one opening is formed. The invention is furthermore directed to a method of manufacturing such a section element.
- Section elements of this kind are known, for example, from WO 2004/055289 A1 and can in particular be used as C-shaped upright sections for dry construction. The elongated base body is provided with a predefined cutting pattern, for example, for manufacturing the section elements. On the selection of suitable cutting patterns, two longitudinal portions of the section element which extend in parallel can in particular be drawn apart in a folding process, whereby a widening of the section element takes place without additional material input. The drawn apart longitudinal sections are in this respect connected to one another via connection elements formed integrally with the longitudinal portions. Corresponding cutting patterns are described in WO 2004/055289 A1 whose content, in particular relating to the cutting patterns described in this document, is herewith explicitly included in the disclosure content of the present application.
- A further possibility of producing widened section elements is described in WO 2007/101594 A1. In this document, a section element is inter alia described which is not produced by a folding process, but rather by a purely widening process, in which slits introduced into the section are widened by drawing up to diamond-shaped openings. Such a section element can also in particular be used for manufacturing upright sections. The content of this document, in particular relating to the cutting patterns described in this document, is also herewith explicitly included in the disclosure content of the present application.
- Corresponding section elements can furthermore also be manufactured without a widening procedure or folding procedure so that the base body, as is, for example, usual with normal upright sections, has a non-elongated, substantially closed design. Openings of the initially named kind can be introduced into such a base body, for example by a punching process. It is disadvantageous in this that the punched out material forms waste, whereby the manufacturing costs for such section elements are increased.
- It is generally often desirable with section elements of the initially named kind, and in particular with upright sections, that leadthrough openings are provided through which, for example, cables, lines or other elongated band-like or cord-like elements as well as pipes or other hollow bodies can be led. Independently of whether such leadthrough openings are produced by punching out corresponding holes in the base body, by the described folding process or by drawing apart, there is the problem that the section element has a reduced stiffness in the region of the produced opening, in particular in a direction transverse to the longitudinal extent of the section element.
- It is an object of the present invention to provide a section element of the initially named kind in which the stiffness in the region of the opening is increased with respect to conventional section elements.
- Starting from a section element of the initially named kind, this object is satisfied in accordance with the invention in that the opening includes at least one edge which is formed transversely to the longitudinal extent of the base body and which is formed at least partly by a bent over portion of the base body; in that the bent-over portion forms an at least double-layer region of the base body together with an adjacent portion of the base body; and in that the bent-over portion is connected to the adjacent portion within the at least double-layer region to increase the stiffness of the section element transversely to its longitudinal extent.
- A method designed in accordance with the invention of manufacturing such a section element is characterized in that slits are introduced into the base body for folding out a portion of the base body; in that the portion is folded out and bent over for forming an opening in the base body, along a kink line extending transversely to the longitudinal extent of the base body and connecting the slits, until the bent over portion forms an at least double-layer region of the base body together with an adjacent portion of the base body; and in that the bent over portion is connected to the adjacent portion within the at least double-layer region to increase the stiffness of the section element transversely to its longitudinal extent.
- In accordance with the invention, the reduced stiffness caused by the opening is compensated in that an at least double-layer region is produced directly in the region of an edge of the opening extending transversely to the longitudinal direction of the section element and the individual layers of this region are connected to one another so that no displacement of the two layers toward one another is possible. At least one of the layers is produced by a material portion which forms at least one region of the opening by folding out of the base body. It is thereby achieved, on the one hand, that the material used for forming the opening is not wasted, but is rather used for stiffening the base body. On the other hand, it is automatically ensured by folding out the portion from the opening that the stiffening effect is present directly in the region of the opening, i.e. in the region of the weak point produced by the opening. In this respect, the term “transverse” is to be understood as any direction which does not extend only in the longitudinal direction of the section element. The transversely extending edge can in particular be formed as a straight line or curved as long as it extends transversely to the longitudinal direction of the section element at least in a part region.
- Furthermore, no supply of a separate part to increase the stiffness is required due to the integral connection of the portion folded out of the base body. The manufacture of the stiffening region is possible in an online process, even at very high speeds such as much higher than 100 m/min, due to the integral connection of the bent over portion to the base body.
- In accordance with an advantageous embodiment of the invention, the edge extends at least regionally substantially perpendicular to the longitudinal extent of the base body. A uniform support edge for lines to be led through the opening or the like is thereby provided. At the same time, the double layered region also extends perpendicular to the longitudinal extent of the base body so that the increased stiffness is also achieved in an ideal fashion in a direction perpendicular to the longitudinal extent of the base body.
- In accordance with a further preferred embodiment of the invention, the bent over portion is connected to the adjacent portion by a pressure joining process such as clinching or crimping, by clamping, squeezing, pressing, welding, screwing, bonding or riveting. The firmer the connection between the bent over portion and the adjacent portion of the base body, the greater the stiffness of the section. In particular a shear movement between the layers of the multilayer region should be prevented using the selected connection process so that, for example, an arching of the section element is prevented.
- The edge is advantageously formed over its total length by the bent over portion. This can be the case, for example, when the base body is not divided into two spaced apart longitudinal portions by drawing apart or by the initially described folding process, but rather substantially forms a closed surface. In this case, after introduction of corresponding slits into the base body, a portion defined by these slits can be bent out of the base body, wherein the edge arising on the bending over of this portion automatically extends over the total length of the opening thereby arising. Since the edge is in this case formed as a kink edge over its total length, it is ensured that the edge is not formed as a sharp edge, but rather has a certain roundness. It is thereby achieved that lines led through the opening can lie on the edge without there being any risk of damage to the lines.
- In accordance with a further advantageous embodiment of the invention, a first part of the edge is formed by the bent over portion. A second part of the edge, which is formed by a non-bent over portion of the base body, advantageously adjoins the first part of the edge. In this respect, the non-bent over portion can in particular form at least a part of the adjacent portion of the base body. The first part of the edge can preferably be formed by a single-layer bent over portion which is adjoined by at least one second part of the edge which is formed by a double-layer bent over portion of the base body.
- This design is in particular sensible when the base body is divided into two longitudinal portions which are drawn apart by the initially described folding process. The openings already arising due to the folding process can additionally be enlarged by correspondingly bent over portions, whereby parts of the edge merging into one another are formed both by the bent over portions of the first longitudinal portion of the base body, for example, and by non-bent over portions of the second longitudinal portion. The bent over portion can in this case form a double-layer region both with the first longitudinal portion and with the second longitudinal portion, wherein the connection of the bent over portion to the respective adjacent portions can be established both in one of these double-layer regions and in both double-layer regions to achieve an increased stiffness.
- In this embodiment, the base body advantageously includes two mutually spaced apart longitudinal portions which extend parallel to one another and are connected to one another at a plurality of connection points via connection elements formed in one piece with the longitudinal portions and in each case bridging the spacing between the longitudinal portions, wherein the opening extends from one of the longitudinal portions beyond the spacing to the other longitudinal portion and the bent over portion forms a region of the edge bridging the spacing between the longitudinal portions.
- In accordance with a further advantageous embodiment of the invention, the opening includes at least two correspondingly formed edges in particular disposed opposite one another. The desired improved stiffness is thereby achieved at both oppositely disposed sides of the opening and thus an even higher stiffness of the section element in the region of the opening overall.
- In accordance with a further preferred embodiment of the invention, the section element is formed as a C section, a U section, an L section, a T section, H sections, a hat section or a Z section. The section element in accordance with the invention can generally also be used for other suitable section types.
- In accordance with a further advantageous embodiment of the invention, the edge is at least regionally engaged over and in particular encompassed by a cover element. This is in particular sensible with a sharp-edged design of the edge since in this case lines led through the opening do not lie on the edge formed with a sharp edge, but rather on the cover element engaging around it. It is thereby ensured that no damage can occur to the elements led through the opening. The cover elements can in this respect not only engage around the support edge, but advantageously also be formed so that the total peripheral edge of the opening is engaged over and in particular encompassed.
- The edge can advantageously be provided at least regionally with a bend, in particular a flange. This can in particular take place as an alternative; generally, also however, in addition to the described cover element. It is also achieved by a bend that the support for lines led through the opening is made rounded despite any formation of the edge as a sharp edge. Damage to the elements led through the opening is thereby in turn avoided.
- Whereas the opening can, as already described, advantageously be formed as a leadthrough opening, in particular for electrical lines, it is generally also possible that the opening satisfies a function different from this. The opening can in particular, for example, also be used as an air passage opening or as a passage opening for other materials such as insulating materials. A stiffening of the section element is also achieved by the design in accordance with the invention in this case.
- A plurality of openings are advantageously provided which are in particular arranged distributed in the longitudinal direction of the base body. The openings can in this respect in particular be present at regular intervals. The flexible use of a section element designed In accordance with the invention for the leading through of lines, cables or the like is further increased by the arrangement of a plurality of openings.
- Further advantageous embodiments of the invention are set forth in the dependent claims.
- The invention will be described in more detail in the following with reference to embodiments and to the drawings; there are shown in these:
-
FIG. 1 a detail of a strip-like material portion with cutting patterns for producing a section element formed in accordance with the invention; -
FIG. 2 a C section made in accordance with the invention, -
FIG. 3 a detail of a further strip-like material portion with a modified cutting pattern; -

FIG. 5 a further C section in accordance with the invention formed with the cutting pattern in accordance withFIG. 3 ; -
FIG. 6 a perspective representation of a cover element; -
FIGS. 7 to 9 perspective representations of further cover elements; and -
FIGS. 10 to 13 four different states during the manufacture of a further embodiment of the invention. -
FIG. 1 shows an elongated,flat material portion 1, which can comprise, for example, metal, plastic or other suitable materials for manufacturing a section element in accordance with the invention. Thematerial portion 1 includes anelongated base body 2 which includes abase portion 3 extending in the longitudinal direction as well as two portions 4 which are laterally adjacent to thebase portion 3 and which can be bent over by 90° in each case along a dashedline 6 for producing limbs 5 (FIG. 2 ) so that an upright section 7 shown inFIG. 2 is produced. In this respect, outwardly disposedmarginal regions 8 of the portions 4 can again be angled by 90° with respect to thelimbs 5 to produce a C-shaped upright section 7 in this manner. - A plurality of
slits base portion 3 of which theslits 9 extend in the longitudinal direction of thebase body 2 and theslits 10 extend perpendicular thereto. Theslits - Two
respective slits 9 are connected bykink lines 11 which are shown as dashed lines and along whichportions 12 of thebase body 2 can be bent over for forming openings 13 (FIG. 2 ).Edges 14 of theopenings 13 are respectively produced by the bent overportions 12 in accordance withFIG. 2 and extend transversely, and in particular perpendicular, to the longitudinal extent of thebase body 2. The bent overportions 12 of thebase body 2 are in this respect bent over so much in accordance withFIG. 2 that they come into areal contract atadjacent portions 15 of thebase body 2 which are shown as hatched areas inFIG. 1 . Together with theadjacent portions 15, the bent overportions 12 thus form double-layer regions 16 of thebase body 2 which are disposed, viewed in each case in the longitudinal direction of thebase body 2, respectively directly adjoining theopenings 13. - As can further be recognized from
FIG. 2 , connection means 17 are provided which are, for example, formed as rivets, and with which the bent overportions 12 are fixedly connected to theadjacent portions 15. Relative movements between the bent overportions 12 and theadjacent portions 15 are prevented by the connection means 17, whereby a stiffening of thebase body 2 is achieved directly in the region of theopenings 13, i.e. in the region weakened in its stiffness by theopenings 13. It can, for example, be achieved by this stiffening effect that, on the use as an upright section, a bending of thebase portion 3 on a lateral load of thelimbs 5, such as can occur on the screwing in of screws on the attachment of planking, is avoided. - The
openings 13 can be used for leading through elements such aselectrical lines 18. Since theedges 14 are each formed by the bent overportions 12, theedges 14 are not made as sharp edges, but rather have a certain rounding. It is thereby avoided that damage takes place to the insulation of theelectrical lines 18 which lie on theedges 14. -
FIG. 3 shows amaterial portion 19 with abase body 35 which has a plurality ofslits 20 which extend obliquely and along the longitudinal extent of thematerial portion 19. Corresponding cutting patterns and modified cutting patterns are described in WO 2004/055289 A1 whose disclosure content relating to the different possible cutting patterns and their use for expanding material portions is explicitly included in the present application. - In addition to the slits forming these known cutting patterns, slits 22 are formed in
FIG. 3 which adjoin twoslits 21 extending obliquely and which extend transversely to the longitudinal extent of thematerial portion 19. A slit 23 extending in the longitudinal direction of thematerial portion 19 adjoins each of theslits 22 and is in turn adjoined by afurther slit 24 extending parallel to therespective slit 22. The ends of the twoslits 24 are in turn connected to one another by aslit 25 extending in the longitudinal direction. - Starting approximately form the center of the
slit 25, a further slit 26 in turn extends parallel to theslits 24 and beyond their ends, with in turn twoslits slit 26 which extend in the longitudinal direction and which each end approximately at the level of theslits 24. The ends of theslits slits 24 in each case via dashedlines kink lines -

base body 35 of thematerial portion 19 is divided into twolongitudinal portions slits 20 to 28, said longitudinal portions being able to be drawn apart transversely to the longitudinal extent of thematerial portion 19 in accordance withFIG. 4 and being connected to one another in the drawn apart state viaconnection elements 43 formed in one piece with thelongitudinal portions longitudinal portions FIG. 4 that anopening 44 which is bounded byedges material portion 19 is created between thelongitudinal portions portions - A

Furtheradjacent portions like portions portions adjacent portions layer regions base body 35 together with the bent overportions - The bent over
portions adjacent portions 49 to 52 via connection means 55, 56 within the double-layer regions FIG. 4 by the slit-shapedopenings 36 and by thetabs like portions tabs openings 36, as can be recognized fromFIG. 4 . -
FIG. 5 shows a C-shapedupright section 57 which is manufactured from amaterial portion 35 in accordance withFIGS. 3 and 4 . Theupright section 57 includes a plurality ofopenings 44 through which respectiveelectrical lines 18 or other supply lines can be led. Since theedges 45 of theopenings 44 on which theelectrical lines 18 lie are only formed as a rounded edge by bending over theportion 34 in theirregions 58 shown at the right inFIG. 5 , there is a risk that theelectrical lines 18 led through will be damaged without additional protective measures if they lie on the other region of theedge 45. - To avoid such damage, in accordance with the representation of the
upper opening 44 inFIG. 5 , the remaining region of theedge 45 can be provided with abend 63, for example with a flange. - Additionally or alternatively, in accordance with the middle representation in
FIG. 5 , theedge 45 can be provided with acover element 59. Thecover element 59 can, for example, have the shape of a sleeve with a longitudinal slit shown inFIG. 6 . Thecover element 59 can in this case be simply plugged onto theedge 45 and can either be held by a corresponding clamping effect or can additionally be squeezed or pressed. Since the upper side of thecover element 59 is made rounded, damage to theelectrical line 18 is prevented in this manner. - The cover element can have different shapes and can, for example, also be made as a hook-shaped
cover element 60 in accordance withFIGS. 7 to 9 . In this respect, an additional fastening of thecover element 60 to thebase body 35 is possible by an extended downwardly projectingportion 61 of thecover element 60, for example by riveting or by another of the initially described kinds of connection. - As shown in the lower region in
FIG. 5 , theopening 44 can also be covered over its total periphery by acorresponding cover element 62. Thecover element 62 thus forms an eyelet which is closed all round and which covers theedge 45 as well as the edges of theopening 44 adjoining it in a similar manner to thecover elements - In contrast to the rectangular shape shown in
FIG. 5 , the cover element or the eyelet can also have rounded regions so that ultimately a correspondingly rounded inner contour of the opening is achieved. In this manner, a circular, an elliptical, an oval or also an angular shape with rounded corners can be achieved, for example. In this respect, the openings themselves can already have a corresponding rounded shape. It is, however, also possible that the openings have an angular shape such as is shown by way of example inFIG. 5 and a rounded inner contour only arises by correspondingly formed cover element or eyelets which e.g. have a larger radial thickness at the corners than in the portions lying between the corners. -
FIG. 10 shows a further embodiment of the invention in which the cutting pattern in accordance withFIG. 3 is modified. For simplification, only the differences from the embodiment in accordance withFIGS. 3 to 5 will be described in more detail in the following. The same or similar elements are in this respect provided with the same reference numerals inFIGS. 10 to 13 as inFIGS. 3 to 5 . - In
FIG. 10 , slits 64 adjoin theslits 21 and respectively extend transversely to the longitudinal extent of thematerial portion 19 and respectively extend only up to thecenter line 65 of thematerial portion 19 or up to the level of the center of the cutting patterns formed by the obliquely extendingslits material portion 19. In this respect, one of theslits 64 extends starting from aslit 21 ending at one side of themiddle line 65 and theother slit 64 extends starting from aslit 21 ending on the other side of thecenter line 65 in the direction toward thecenter line 65. - A
respective slit 66 which runs along thecenter line 65 and which is in turn adjoined by afurther slit 67 extending oppositely and parallel to therespective slit 64 adjoins theslits 64. Arespective slit 68 extending perpendicular to therespective slit 67 is formed at the ends of theslits 67 and thus extend parallel to one another and parallel to the longitudinal extent of thematerial portion 19. The centers of the twoslits 68 are connected to one another via aslit 69 extending parallel to theslits 67. Theslits 68 further wore each extend beyond theslits 67 and end in obliquely extendingslits 70 which are connected to one another viakink lines 71 shown in dashed lines. In a similar manner, the ends of theslits 67 are connected to theslits 68 viakink lines 72 shown in dashed lines. Corresponding to the obliquely extendingslits 70,respective slits 73 which extend obliquely and through whichtriangular holes 74 are created between theslits slits FIG. 10 . Both the obliquely extendingslits 70 and the obliquely extendingslits 73 are only provided optionally and prevent corners with sharp edges from arising at the resulting section element. These slits can therefore also generally also be omitted. To avoid corners with sharp edges, theslits -
First portions 75 which are adjoined bysecond portions 76 bordered between the kink lines 71 and 72 and theslits slits third portions 77 are formed between theslits - After introduction of the cutting pattern shown in
FIG. 10 , as already described analogously with respect toFIG. 4 , the twolongitudinal portions base body 35 are drawn apart. A spacing thereby arises between thelongitudinal portions connection elements 43, as is shown inFIG. 11 . - The
portions 74 are subsequently each bent over along the kink lines 72, whereby anopening 78 shown inFIG. 12 is produced. - In a further step, the
portions 75 already bent over once are bent over a second time together with theportions opening 78 receives its final size as is shown inFIG. 13 .
