Description

metal profile

The present invention relates to a metal profile with an elongated base portion, wherein the base portion comprises at least two longitudinal portions which are parallel to each other and are interconnected at a plurality of connection points via integrally formed with the longitudinal sections connecting elements.

Metal profiles of this type are known, for example, from WO 2004/055289 A1 and can be used in particular as C-shaped upright profiles for drywall construction. To produce the metal profiles, an elongated metal element is provided, for example, with a predetermined cutting pattern, which serves to widen the metal element and to produce the connecting elements. Corresponding cutting patterns are described in WO 2004/055289 A1, the content of which, in particular with regard to the patterns described in this publication, is hereby explicitly included in the disclosure content of the present application.

As described in WO 2004/055289 A1, two longitudinal sections of the metal element can be pulled apart in a folding process, so that a widening of the metal element takes place without additional material and the extended longitudinal sections over the integral with the longitudinal sections pictured fasteners are interconnected. In such metal profiles and in particular in stud profiles, it is often desirable that feedthrough openings are provided, can be passed through the example, cables, wires or other elongated, band or cord-shaped elements. If such leadthrough openings are produced by punching out corresponding holes in the base section, then there is the problem that the edges of the leadthrough openings produced are relatively sharp-edged and when passing cables or lines their insulations are damaged or the elongate elements can be completely severed.

In addition, depending on the patterns used in the expansion of the metal profile, a distance between the longitudinal sections of the base portion arise. If the lead-through opening is arranged such that it extends over this distance, on the one hand the stiffness of the metal profile in this area is weakened and on the other hand an element guided through the lead-through opening can be formed in the channel formed between the two longitudinal sections of the channel Enter metal profiles. This is undesirable, as this can lead to jamming of the element and at the same time the risk of damaging the element is further increased.

It is an object of the present invention, a metal profile of the type mentioned above in such a way that cables, wires or the like can be passed through the metal profile, without causing damage to the elements passed through, while preventing jamming of the lines and a high rigidity of the metal profile should be given. Based on a metal profile of the type mentioned above, this object is achieved in that between the longitudinal sections a predetermined distance is present, that the distance from the connecting elements for connecting the longitudinal sections is partially bridged that at least one passage opening is provided in the base portion in that the lead-through opening extends from one of the longitudinal sections over the distance to the other longitudinal section and that at least one spaced-apart, two-part edge of the leadthrough opening is covered by a separate cover element extending along the edge of the one Longitudinal portion of the base portion extends over the distance to the other longitudinal portion.

The cover element realizes several essential functions in a single component. On the one hand, the sharp edge of the leadthrough opening, which is produced, for example, in a punching process, overlaps, so that the lines, cables or the like which are guided through the leadthrough opening do not come into abutment on the sharp edge but on the cover element. As a result, damage to the insulation of corresponding cables, lines or the like or cutting through correspondingly guided through the passage opening guided elements is reliably prevented. At the same time it is ensured by the cover that a generated by the pulling of the longitudinal sections distance between the longitudinal sections is bridged, so that through the

Lead-through hole guided cables, wires or the like can not fall into this distance and be trapped there, for example. Finally, by the cover member is weakened in the region of the metal profile, which is weakened by the passage opening and the distance formed between the longitudinal sections, creates an additional connection between the longitudinal sections, whereby the rigidity of the metal profile is increased in this area.

According to an advantageous embodiment of the invention, the cover extends substantially over the entire length of the two-part edge. This ensures that, irrespective of the position of the cable, cables or the like routed through the passage opening, their insulation is reliably protected. Furthermore, maximum stability of the metal profile is achieved in this case.

According to another preferred embodiment of the invention, the cover is firmly connected to the longitudinal sections. The covering element can in this case with the longitudinal sections, for example by a pressure joining method such as clinching, by jamming, crimping,

Be connected pressing, welding, screwing or riveting. The stronger the connection between the cover element and the longitudinal sections, the greater the rigidity of the metal profile.

According to a further advantageous embodiment of the invention, the edge of the passage opening is overlapped by the cover and in particular comprises. This can be useful, for example, if in the region of the two-part edge there is no sufficient surface of the base section to which the cover element can be fastened, for example, by a pressure joining method. In this case, the cover may arise, for example, from a longitudinally slotted sleeve, which is pushed over the two-part edge and squeezed or pressed with the longitudinal sections. According to a further advantageous embodiment of the invention, the cover element consists of a separate from the formation of a passage opening from a base portion of a metal member. The cover in this case thus consists of a waste element, which is obtained when forming a passage opening. The reuse of this waste element thus results in the formation of the cover no additional material requirements, so that the cost of a metal profile according to the invention are not increased despite improved properties. In this case, the waste element may be the part that is to be provided with the cover element when it is being produced

Passage opening is incurred or to a waste element that is incurred in generating a different feedthrough opening.

Preferably, the cover is formed as a stamped part. Furthermore, the cover advantageously has a substantially rectangular shape, whereby a simple overlap of the two-part edge of the passage opening is possible and at the same time by the cover a straight contact edge for the guided through the passage opening lines, cables or the like is formed.

According to a further preferred embodiment of the invention, the cover element comprises a bent edge which extends over the distance and in particular has a rounded upper side. This design ensures that the insulation of a guided over the bent edge line, a cable or the like is not damaged while preventing hooking.

According to a further advantageous embodiment of the invention, the passage opening has a substantially rectangular, in particular a substantially square shape. Advantageous is the length of the Feedthrough opening in the longitudinal direction of the metal element substantially equal to the width of the passage opening including the distance between the longitudinal sections of the metal element. As a result of this design, the waste elements arising during the production of the feed-through openings are automatically of optimal length in order to be able to completely cover the two-part edge resulting from the pulling apart of the longitudinal sections, including the distance between the longitudinal sections.

According to a further advantageous embodiment of the invention, the passage opening comprises two two-part edges, wherein both edges are each covered by a cover. In particular, the two edges are opposite each other and preferably transverse to the longitudinal extent of the Metallpro fils. This ensures that, regardless of the installation direction of the metal profile in each case the lower edge of the passage opening is covered by a cover. Since cables, lines or the like routed through the lead-through opening normally rest on the lower edge of the passage opening, a protected support of the cables, lines or the like is thus achieved independently of the installation direction of the metal profile.

According to a further preferred embodiment of the invention, a plurality of passage openings are formed in the base portion in particular at regular intervals. These can each be covered by a cover element designed according to the invention. As a result, the flexibility in performing the lines, cables or the like is further increased. According to a further advantageous embodiment of the invention adjoins the side of the base portion at least one opposite the base portion angled leg. Advantageously, correspondingly angled legs can be provided on both sides of the base section. Depending on requirements, a wide variety of profiles can be produced. The connecting elements can in principle be formed in the base section, in a single leg, in a plurality of legs or in the base section and the legs. It is also possible for the base section itself to comprise an angling, the spacing being arranged in the region of the bend or close thereto. The cover is then preferably designed as an angled element in order to achieve a coverage of the distance in this case. The bending of the spacer element advantageously extends substantially parallel to the bending of the base section.

Preferably, the metal profile is designed as a C-profile, U-profile, L-profile or Z-profile. In principle, the metal profile according to the invention can also be used for other suitable types of profiles.

In accordance with a further preferred embodiment of the invention, the longitudinal sections are pulled apart by the predetermined distance by a drawing or stretching method. In principle, however, the invention can also be used if the predetermined distance is generated by another method.

According to a further preferred embodiment of the invention, the connecting elements comprise connecting webs, via which they are connected to the longitudinal sections. In this case, the connecting webs are in particular connected both with respect to the longitudinal sections and with respect to the areas of the connecting elements bridging the gap. folds. In principle, however, the invention is also applicable to another embodiment of the connecting elements.

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

The invention will be described in more detail below by means of embodiments with reference to the drawings; in these show:

Fig. 9 is an inventively designed C-profile.

Fig. 1 shows an elongate, flat metal element 1 comprising a longitudinally extending base portion 2 and two laterally adjacent to the base portion sections 3, which for generating legs 4 (Fig. 9) respectively along a dashed line 5 by 90 ° can be bent so that a stator profile 6 shown in Fig. 9 is generated. In this case, outer edge regions 7 of the sections 3 can again be angled relative to the legs 4 by 90 ° in order to produce a C-shaped upright profile 6 in this way.

The base portion 2 comprises two mutually parallel longitudinal sections 8, which are formed symmetrically with respect to a longitudinal axis 9 of the metal element 1.

In the base portion 2, a plurality of cuts are formed. Along the longitudinal axis 9, a plurality of longitudinal sections 10 extend, from which a plurality of obliquely extending cuts 11 extend into the base section 2 to form connecting elements 12. Parallel to the oblique sections 11 further oblique sections 13 are provided, wherein each two outer sections 13 are connected by parallel to the longitudinal axis 9 extending cuts 14. While three mutually parallel oblique sections 11, 13 are shown in FIG. 2, basically only two or more than three parallel oblique sections can be provided in each case. Between two connecting elements 12 are provided by the longitudinal section 10 vertically outwardly extending cuts 15 whose outwardly facing ends are connected to each other via parallel to the longitudinal axis 9 extending cuts 16.

By means of the cuts 15, 16 and the region 10 'of one of the longitudinal cuts 10 arranged between the cuts 15, two parts 17 are cut out of the base section 2 which are used to form cover elements, as will be described below.

After or during the production of the longitudinal cuts 10 and of the cuts 11 and 13 to 16, for example by rotary blanking, laser cutting or another suitable cutting or punching process, the longitudinal sections 8, together with the adjoining sections 3, become transverse to the longitudinal axis 9 pulled apart, as indicated in Fig. 1 by arrows 18 so that the shown in Fig. 2, exploded state of the metal element 1 is achieved.

From Fig. 2 it can be seen that by pulling apart a distance 19 between the longitudinal sections 8 is formed, which is partially bridged by the connecting elements 12 for connecting the longitudinal sections 8. By the distance 19, a longitudinal channel 20 is formed, through which the longitudinal sections 8 are separated from each other.

During expansion of the metal element 1, the metal regions of the base section 2, which form connecting webs 21 of the connecting elements 12 and are present between the oblique sections 11 and 13, are folded over both the longitudinal sections 8 and the main sections 22 of the connecting elements 12 bridging the distance 19. Furthermore, upon expansion of the metal element 1, a lead-through opening 23 is created whose width and height are substantially equal and which extends from the longitudinal section 8 on the left in FIG. 2 over the distance 19 into the longitudinal section 8 shown on the right in FIG ,

Due to the longitudinal channel 20 formed by the distance 19, the edges of the leadthrough opening 23 extending transversely to the longitudinal axis 9 are each formed as two-parted edges 24, each with two halves 24 '. The two-part edges 24 together with parallel to the longitudinal axis 9 extending edges 35 and two each of the two halves 24 'of the two-part edges 24 connecting, indicated in Fig. 2 by dashed lines 25 imaginary connecting lines a border of the passage opening 23. In the context of the present application Therefore, the two-part edge 24 is referred to as over the distance 19 across extending two-part edge.

The passage opening 23 is used for passing elongated elements, such as lines, cables, cords, wires,

Ribbons or the like. The problem with this is that the two-part edges 24 are usually formed relatively sharp-edged, so that there is a risk that the insulation of corresponding cables or cables are damaged or the elongated elements can be completely cut through. Furthermore, there is a risk that by the

Through opening 23 guided through elongated elements do not come to rest on one of the halves 24 'of the two-part edge 24, but slip into the longitudinal channel 20 into it and jam there. Finally, the stiffness of the metal element 1 is reduced in the region of the relatively large passage opening 23 with respect to the remaining areas. In order to eliminate these problems, according to the invention, a cover element bridging the distance 19 is fastened to the longitudinal sections 8, as will be explained in more detail below with reference to different exemplary embodiments.

In Fig. 3, the parts 17 are shown, which are separated during the production of the cuts 15, 16 and the portion 10 'of the longitudinal section 10 from the base portion 2 out. The parts 17 are formed as elongated, rectangular parts, wherein their length corresponds in each case to the width of the passage opening 23 in the expanded state of the metal element 1 transversely to the longitudinal axis 9. The parts 17 are thus waste elements, which are usually supplied to the scrap metal utilization.

According to the invention, in a first embodiment, each of the parts 17 is respectively bent on one of its longitudinal sides 26, so that a cover element 27 according to FIG. 4 is formed. The cover member 27 thus has a bent edge 28 with a rounded top.

The two corresponding to cover members 27 formed parts 17 are respectively connected according to Figures 5 and 6 with the longitudinal sections 8 via clinching 29, wherein the bent edge 28 extends parallel to the two-part edges 24 and thus they are covered by the cover 27. When passing a cable 30 through the passage opening 23, the cable 30 is thus on the rounded, bent edge 28, so that there is no risk of damaging the insulation of the cable 30. In addition, bridging the gap 19 ensures that the cable 30 can not fall into the longitudinal channel 20 and become jammed there. Ultimately, by the one with the two longitudinal sections 8 firmly connected cover member 27 also increases the rigidity of the metal element 1 in this area.

According to FIG. 4, the parts 17 can also be reshaped to form a cover element 31 as a sleeve 32 with a longitudinal slot 33. This is particularly advantageous if in the region of the two-part edges 24 is not enough material for attachment such as Verclinchen, riveting or screwing available. According to FIG. 8, the cover element 31 can in each case be attached to the two-part edges 24 in such a way that they are overlapped laterally by the longitudinal slot 33 in each case bounding longitudinal edges 34 of the cover element 31. Advantageously, the cover 31 extends again over the entire width of the two-part edges 24th

For further attachment, the cover element 31 can then be squeezed or pressed with the longitudinal sections 8, so that a secure connection is created between the cover elements 31 and the longitudinal sections 8 of the metal element 1.

As can be seen from Fig. 8, is also in this case a through the

Lead-through 23 guided through cable 30 to the rounded top of the cover 31, so that no damage to the insulation of the cable 30 can be made.

In Fig. 9, a manufactured from the metal element 1, inventively designed C-shaped upright profile 6 is shown in which through the passage opening 23, a cable 30 is guided therethrough. For reasons of clarity, no further passage openings 23 or connecting elements 12 are drawn in at the lower area of the upright profile 6. However, depending on the requirement, Re implementation openings 23 and connecting elements 12 may be provided, which may be formed according to the above-described passage openings 23 and connecting elements 12.
