EP2467545B1 - Profile element and method for manufacturing a profile element - Google Patents

Description

The present invention relates to a profile element, in particular a construction profile, for example a drywall, facade, plaster, screed, tile or cable carrier profile or a shelf or drainage rail, with a particular metallic or plastic elongated profile body in which a A plurality of openings is formed, according to the preamble of claim 1 or 2. Furthermore, the invention is directed to a method for producing such a profile element.

Profile elements of this type are used, for example, as C-shaped upright profiles for drywall, wherein the openings provided in the profile body of the profile element can serve, for example, as leadthrough openings for cables, lines or other elongate, band or cord-shaped elements, as well as pipes or other hollow bodies. Furthermore, these openings can also serve for ventilation or allow the penetration of fillers such as insulation material.

In known profile elements, these openings are introduced, for example, by a punching process. The disadvantage of this is that the punched material forms rejects, whereby the manufacturing costs for such profile elements are increased.

A profile element of the type mentioned is from the US 5,661,881 A known. To produce the profile element, the two longitudinal sections in overlapping areas welded together or crimped together.

It is an object of the present invention to provide a profile element of the type mentioned, which is simple and inexpensive to produce and with reduced material costs. Furthermore, a method for producing such a profile element is to be specified.

Starting from a profile element of the type mentioned above, the object concerning the profile element is achieved by the features of claim 1 or claim 2

The part of the object relating to the method is achieved on the basis of a method of the type mentioned above by the features of claim 7 or claim 9

According to the invention, no waste is thus generated to produce the openings of the profile body, so that material can be saved compared to, for example, a production by punching. In other words, a wider configuration of the profile element is achieved by the moving apart of two separately formed longitudinal sections with the same amount of material. Due to the meandering formed longitudinal edges regions of the longitudinal sections are generated, which overlap after moving apart, wherein in these areas connecting means are formed. Thus, the production of the inventively embodied profile element is very easy to carry out, since despite the originally separate formation of the two longitudinal sections they are automatically connected to each other when moving apart again by the longitudinal sections are collapsed when moving apart. The term "across" is any direction to understand that does not extend exclusively in the longitudinal direction of the profile element or its longitudinal sections. In particular, the term "transverse" can thus mean perpendicularly but also obliquely to the longitudinal extension of the profile element or of the longitudinal sections.

The connecting means may preferably be formed integrally with the longitudinal sections. However, it is also conceivable that the connecting means are formed as separate components which are attached to the overlapping regions of the longitudinal sections.

According to the invention, in each case extending from the meandering longitudinal edge into the overlapping regions of the longitudinal sections extending transversely to the longitudinal direction of the respective longitudinal section slots, wherein the longitudinal sections are plugged together by means of the slots. The connecting means are thus formed in this embodiment by simple slots, which allows a very simple and inexpensive manufacturing process.

Alternatively, in the overlapping regions of one or both longitudinal sections, plug-in tabs may be formed, which project into plug-in openings formed in the overlapping regions of the respective other longitudinal section. The plug-in tabs can be molded out, for example, directly from the material of the longitudinal sections. Also in this embodiment, a very simple and cost-effective design of the connecting means in the form of insertion tabs and plug-in openings is possible.

Advantageously, each longitudinal section comprises a plurality of in particular T-shaped or web-shaped sections which are bounded by the meander-shaped longitudinal edges and by one in particular as a straight line Protrude longitudinal strips trained area of the respective longitudinal section. By the particular web-shaped sections or the crossbar corresponding T-shaped sections, said overlapping regions are formed, which protrude transversely to the longitudinal extent of the longitudinal sections relative to the adjoining longitudinal regions of the longitudinal sections. In addition, when formed as T-shaped portions, the overlapping portions are longitudinally opposed to the central webs of the T-shaped portions in the longitudinal direction of the longitudinal portions.

Preferably, the connecting means are designed as latching connection means. As a result, not only the movement apart of the longitudinal sections is limited, but after complete mating also prevents an opposite movement to release the connector.

According to a further advantageous embodiment of the invention, the longitudinal sections are connected to each other in addition to the connector via the connecting means by further connecting means Thus, the longitudinal sections, for example, by a Druckgesgeverfahren as Verclinchen or crimping, by jamming, crimping, compression, welding, screwing, gluing or riveting or another suitable connection method additionally be interconnected. This additional connection can be provided in particular in the overlapping areas and optionally additional areas of the longitudinal sections.

The separate longitudinal sections can already be produced originally from separate material sections. These can be, for example have the same or different thicknesses and consist of the same or different materials.

Advantageously, the separate longitudinal sections can be produced from an originally uniform material section. In this case, at least one meander-shaped slot extending in the longitudinal extent of the starting material can be introduced into an elongated strip-shaped starting material, by means of which the starting material is divided into the two separate longitudinal sections.

In both cases, the connector between the two longitudinal sections can be achieved by a corresponding movement apart of the longitudinal sections. While in the production of an originally one-piece starting material, the two longitudinal sections can be arranged after introduction of the meandering slot already in their starting position for moving apart, the two longitudinal sections can be initially brought into a corresponding starting position to each other in the production of two different material sections, in the example Form edge portions of the meandering longitudinal edges of the two longitudinal sections in a direction transverse to the longitudinal extension of the profile element or the longitudinal sections undercuts. In both cases, by the movement apart of the longitudinal sections in a direction transverse to its longitudinal extension, the desired connector can be achieved automatically, since during the overlapping of the regions of the two longitudinal sections when moving apart the corresponding connecting means are automatically engaged. In addition, it is ensured by the connecting means that the longitudinal sections can not be pulled apart completely, but after complete mating the longitudinal sections by adjacent edges of the connecting means, the movement is limited.

It is also possible that prior to moving the longitudinal sections apart transversely to their longitudinal extent, the longitudinal sections are displaced substantially in the longitudinal direction relative to each other in order to achieve a desired starting position for the moving apart. The starting position is advantageously chosen so that the overlapping areas to overlap so overlap in the subsequent moving apart of the longitudinal sections so that the connecting means engage with each other.

Advantageously, before being moved apart, the regions of the longitudinal sections to be overlapped are at least partially set up, for example bent up. This ensures that the provided connecting means actually engage with one another and that the two longitudinal sections can not be moved apart without mutual engagement of the connecting means.

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

Fig. 1 shows a profile element 1, which is designed as a C-profile. The profile element 1 comprises a profile body 2, which has a profile web 3 and two laterally adjoining profile leg 4, which are each angled at right angles to the profile web 3. The free longitudinal edges of the profile legs 4 are each angled in turn by 90 ° to form the C-profile. In principle, the profile element 1 according to the invention can also be designed, for example, as U-profile, L-profile, T-profile, H-profile, top-hat profile or Z-profile.

In the profile web 3, a plurality of openings 5 is formed, which can serve for example as through holes for cables or other elements to be laid.

The openings 5 of the profile element 1 are produced according to the invention without loss of material, as described below with reference to the Fig. 2 to 7 is explained in more detail.

Fig. 2 shows a strip of material 6, for example, a metal strip, which serves as a starting material for the profile body 2. While in the Fig. 2 to 7 in each case only a relatively narrow region of the material strip 6 is shown, which is ultimately used to form the profile web 3, at the outer edges 7, 8 each further material areas adjoin, for example, the profile legs 4 are formed by corresponding bending.

In the material strip 6, a meandering slot 9 extending in the longitudinal extent of the material strip 6 is formed, through which the material strip 6 and thus the profile body 2 is divided into two separate longitudinal sections 10, 11. Through the meandering slot 9, the longitudinal sections 10, 11 each receive a meander-shaped longitudinal edge 12, 13, which in the illustration according to FIG Fig. 2 fit seamlessly together. The meandering longitudinal edges 12, 13 each comprise longitudinally extending and perpendicularly extending edge portions, with edge portions 14 of the longitudinal edge 12 with edge portions 15 of the longitudinal edge 13 in a direction transverse to the longitudinal extent of the material strip 6 and thus also the profile element 1 undercuts form.

According to Fig. 3 are in addition to the meandering slot 9 each transverse to the longitudinal extent of the longitudinal sections 10, 11 extending slots 16, 17 introduced into the longitudinal sections 10, 11. The slots 16 each extend from the undercut edges 14 into regions 28 of the longitudinal section 10, while the slots 17 each extend from the undercut edges 15 into regions 29 of the longitudinal section 11. Depending on a slot 16 and a slot 17 are arranged so that they are aligned.

T-shaped sections 18, 19 of the longitudinal sections 10, 11 are formed by the meander-shaped longitudinal edges 12, 13, the parts of the transverse bars of the T-shaped sections 18, 19 projecting in the longitudinal direction of the strip of material 6 in each case forming the areas 28, 29, in which the slots 16, 17 are formed. Furthermore, the T-shaped sections 18, 19 comprise web-shaped regions 33, 34, by way of which the transverse bars of the T-shaped sections 18, 19 are connected to straight longitudinal strips 36 of the longitudinal sections 10, 11.

To produce the final shape of the profile web 3, the undercut edge portions 14, 15 are first in the same direction set up or bent out of the plane of the material strip 6, as in Fig. 4 is shown.

Subsequently, the two longitudinal sections 10, 11 are pulled apart according to two arrows 20, 21 transversely to the longitudinal extent of the material strip 6, wherein due to the aligned arrangement of the slots 16, 17, the longitudinal sections 10, 11 are inserted into each other until the areas 28, 29 of the longitudinal sections 10, 11 overlap each other and the lying within the sections 28, 29 ends 22, 23 of the slots 16, 17 abut each other, whereby a further pulling apart of the longitudinal sections 10, 11 is prevented. The corresponding state when the longitudinal sections 10, 11 are pulled apart completely is shown in FIG Fig. 6 shown.

By pulling the longitudinal sections 10, 11 at the same time of the sections 24, 25 of the meandering longitudinal edges 12, 13 bordered openings 5 are formed without a scrap of material is generated.

In addition to the connector of the longitudinal sections 10, 11, these can according to Fig. 7 be connected by other connecting means such as welds 27 with each other. The welds 27 or other suitable connection means extend in particular also over the slots 16, 17 and over the overlapping regions 28, 29 of the longitudinal sections 10, 11 away.

As it is in Fig. 7 is indicated, 6 stiffening beads 32 may be formed in the material portion. In particular, these stiffening beads may be formed in the web-shaped regions 33, 34 of the T-shaped sections 18, 19 and transversely to the longitudinal extent of the material section 6 run. Also in the region of the longitudinal edges 7, 8 corresponding stiffening beads 35 extending in the longitudinal direction of the material section 6 may be formed, which may in particular be in connection with the reinforcing beads 32, as shown in FIG Fig. 7 is shown.

The in the Fig. 8 to 10 illustrated embodiment differs from the previously described embodiment only in that instead of the slots 16, 17, insertion tabs 30 and insertion openings 31 in the areas 28, 29 of the longitudinal sections 10, 11 are formed.

The plug-in tabs 30 can, for example, be formed directly out of the sections 28, 29, as can be seen in particular Fig. 9 is recognizable. When moving apart the longitudinal sections 10, 11 transversely to its longitudinal extent, the free ends of the insertion tabs 30 in the insertion openings 31, until the in Fig. 10 shown end state is reached, in which the tabs 30 protrude through the insertion openings 31 and prevent further movement apart of the longitudinal sections 10, 11 against each other. In order to facilitate insertion of the insertion tabs 30 into the insertion openings 31, the insertion tabs 30 and the insertion openings 31 containing portions 28, 29 of the longitudinal sections 10, 11 may be bent out of the plane of the material strip 6 in opposite directions before pulling apart the longitudinal sections 10, 11 become.

In the embodiment according to Fig. 11 the tabs provided in the areas 29 are formed as latching tabs 37. The locking tabs 37 are formed out of the material of the longitudinal section 11 in the regions 29 and have a free end having starting slope 38 and an adjoining connected to the longitudinal portion 11 detent slope 39th

The insertion openings provided in the regions 28 are formed as bridge-shaped tabs 40, which are stamped out of the material of the longitudinal section 10.

How out Fig. 12 can be seen, the locking tabs 37 pass when moving apart of the longitudinal sections 10, 11 through the bridge-shaped tabs 40, whereby a latching connection of the longitudinal sections 10 and 11 is achieved.

Corresponding bridge-shaped tabs 40, for example, in the embodiment of the Fig. 8 to 10 be provided instead of the insertion openings 31. In this case, the bridge-shaped tabs 40 can extend downwards out of the material, starting from the regions 28, so that the plug-in tabs 30 can enter the bridge-shaped tabs 40 when the longitudinal sections 10 and 11 move apart.

In the FIGS. 13 and 14 a further embodiment of the invention is shown in which no T-shaped but web-shaped sections 41, 42 are formed by the meandering slot 9, each of the rectilinear longitudinal strips 36 of the longitudinal sections 10, 11 protrude and transversely to the longitudinal extent of the material section. 6 extend. In this embodiment, the web-shaped sections 41, 42 comprise the regions 28, 29 in which the connecting means, in the example designed as plug-in tabs 30 and plug-in openings 31, are provided. In principle, the connecting means can also be used in this case, for example be designed as latching tabs and as bridge-shaped tabs or in any other suitable manner.

In order to bring the regions 28, 29 into overlapping when the longitudinal sections 10, 11 are moved apart, in this embodiment the longitudinal sections 10, 11 are initially displaced in the longitudinal direction relative to one another according to arrows 43, 44, until a web-shaped section 41 overlaps a web-shaped section 42 , Subsequently, the longitudinal sections 10, 11 according to arrows 45, 46 are moved apart until the tabs 30 engage in the insertion openings 31, as in Fig. 14 is shown. In contrast to the previously described embodiments, the openings 5 are not offset from one another in this embodiment, but formed in the longitudinal direction immediately behind one another and have a greater width, as it is made Fig. 14 is recognizable.

From the illustration to Fig. 15 It can be seen that the positioning of the areas 28, 29 before the moving apart of the longitudinal sections 10, 11 can also be such that the resulting by the slots 16, 17 outer portions 28 ', 29' are raised at their free ends, so that the Slits 16, 17 are slightly widened. In this way, a secure mating of the longitudinal sections 10, 11 is ensured when moving apart.

Fig. 16 shows an embodiment of the invention, on the one hand on the in Fig. 2 illustrated, that is, that the meandering slot 9 is formed such that T-shaped portions 18, 19 are generated.

For the manufacture of the profile element 1, however, on the other hand, the longitudinal sections 10, 11 as to FIGS. 13 and 14 described first in accordance with the arrows 43, 44 in the longitudinal direction against each other until the web-shaped portions 33, 34 of the T-shaped sections 18, 19 are superimposed. Only in the next step, the longitudinal sections 10, 11 are moved apart transversely to their longitudinal extent, until they are inserted into each other by means of the slots 16, 17, as in Fig. 16 is shown.

In this variant, the resulting openings 5 have compared to the previously described embodiments both in the longitudinal and in the transverse direction of enlarged dimensions.

Also in this variant, the connecting means, as in all other variants, not only be formed by slots, but also by the other described types of connecting means.

Incidentally, the embodiments according to the Fig. 8 to 16 all to the embodiment according to the Fig. 2 to 7 include described features. In particular, the longitudinal sections 10, 11 of these further embodiments can be connected to each other by additional connecting means after the complete pulling apart, as has already been described to the first embodiment.
