Abstract

A hollow profile (11), which is constructed for absorbing loads in the longitudinal and lateral directions, has a closed cross-section with a circular external circumference (12). Arranged opposite on the external circumference (12) are external longitudinal grooves (13, 14) whose groove base runs concentrically with respect to the external circumference (12). Arranged in pairs on the inside of the hollow profile (11) are ribs (17, 18, 19, 20) which between them form internal longitudinal grooves (21, 22), which run in the axial direction of the hollow profile (11) and are shaped differently, for holding reinforcing inserts. With the aid of the external longitudinal grooves (13, 14), on the one hand attachment parts can be fixed in a defined circumferential position, in a similar manner to that in the case of rectangular cross-sectional shapes, and on the other hand they provide orientation for the circumferential position of a reinforcing insert. <IMAGE>

Description

Hohlprofil Die Erfindung bezieht sich auf ein Hohlprofil mit gesehlossenem Querschnitt nach dem Oberbegriff von Patentanspruch 1, zur Aufnahme von Lasten in Längs- und Querrichtung.Hollow profile The invention relates to a hollow profile with a closed Cross-section according to the preamble of claim 1, for absorbing loads in Longitudinal and transverse direction.

Hohlprofile it geschlossene Querschnitt sind bekannt. Sylindrische Rohre besitzen zwar eine kleine Oberfläche pro Ldngeneinheit im Verhältnis zum Querschnitt Aber die Lage von eingeschobenen Verstbrkungen in Bezug auf eine bestimmte Umfangs richtung ist von außen nicht ersichlich. Dadurch ergeben sich bei der Weiterverarbeitung und bei der Montage Schwierigkeiten.Hollow profiles with a closed cross section are known. Cylindrical It is true that pipes have a small surface area per unit length in relation to their cross-section But the position of inserted reinforcements in relation to a certain extent direction cannot be seen from the outside. This results in further processing and difficulties during assembly.

Hohlprofile mit rechteckigem Querschnitt lassen zwar eine Orientierung von Außen flachen zur Lage etweiger Verstarkungs einschubes zu, der Rechteckquerschnitt erfordert aber einen gößeren Werkstoffeinsatz im Verhältnis zur Oberflache pro Ldngeneinheit als kreisförmige Querschnitte.Hollow profiles with a rectangular cross-section allow an orientation from the outside flat to the location of some reinforcement inserts, the rectangular cross-section but requires a larger amount of material in relation to the surface area per unit of length as circular cross-sections.

Es ist nun Aufgabe der Erfindung ein Hohlprofil mit geschlos; senem Querschnitt zu schaffen, das die die Vorteile kreisförmiger und rechteckiger Querschnittsform in sich vereinigt.It is now the object of the invention to provide a hollow profile with closed; senem To create cross-section that has the advantages of circular and rectangular cross-sectional shape united in itself.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen don Patentanspruch 1 gemäß der Erfindung in vorteilhafter Weise gelost.This task is done with the characterizing features of the patent claim 1 solved according to the invention in an advantageous manner.

Die weitere Ausgestaltung der Erfindung ergibt sich aus den Merkmalen der Ansprüche 2 bis 90 Die zenit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß trotz kreisförmigem Querschnitt am Außenumfang eine Orientierungsmöglichkeit fUr die Umfangslage eines Verstörkungseinschubes gegeben ist, daß sich endseitig jeweils eine zylindrische Aufnahme fur Einteckteile ergibt, die auf Grund der Profilierung ohne Nacharbeit einen Ausgleich von Übermaß zuläßt und daß mit Hilfe der Außenldngsnuten An bauteile in definierter Umfongslage fixierbar sind.The further embodiment of the invention results from the features of claims 2 to 90 The advantages achieved by the invention consist in particular in the fact that despite the circular cross-section on the outer circumference there is a possibility of orientation For the circumferential position of a reinforcement insert it is given that it is at the end each results in a cylindrical receptacle for insert parts, which is due to the profiling allows for a compensation of oversize without reworking and that with the help of the Außenldngsnuten Can be fixed to components in a defined circumferential position.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachstehend näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Ein Hohlprofil 11 mit kreisförmigem Außenumfang 12 weist zwei Außenlangsnuten 13,14 auf, die gegenüberliegend, symmetrisch zur Mittelebene 15 angeordnet sind. Die Flanken 16 der Außenlängsnuten 13,14 sind zueinander und zur Mittelebene 15 planparallel. Der Nutgrund jeder Außenlöngsnut 13, 14 verlauft konzentrisch zum kreisförmigen Außenumfang 12 des Hohlprofils 11 Auf der Innenseite des Hohlprofils 11 sind Rippen 17,18,19,20 symmetrisch zur Mittelebene 15 angeordnet, die zwischen sich in Achsrichtung des Hohlprofils 11 verlaufende Innenldngsnuten 21 bzw. 22 einschliessen. Die Innenlängsnuten 21 weisen zueinander planparallele Flanken und einen ebenen Nutgrund auf, während die Innenlöngsnuten 22 mit zueinander geneigten Flanken und konkavem Nutgrund ausgebildet sind.A hollow profile 11 with a circular outer circumference 12 has two outer longitudinal grooves 13, 14, which are arranged opposite one another, symmetrically to the central plane 15. The flanks 16 of the outer longitudinal grooves 13, 14 are relative to one another and to the central plane 15 plane-parallel. The groove base of each Außenlöngsnut 13, 14 is concentric to the circular outer circumference 12 of the hollow profile 11 on the inside of the hollow profile 11 ribs 17,18,19,20 are arranged symmetrically to the central plane 15, which between include Innenldngsnuten 21 and 22 running in the axial direction of the hollow profile 11. The inner longitudinal grooves 21 have flanks that are plane-parallel to one another and one that is flat Groove base, while the Innenlöngsnuten 22 with mutually inclined flanks and concave groove base are formed.

Die Nutgrundwände der Außenldngsnuten 13,14 liegen mit ihren Innenflächen 23,24 auf gleichem Durchmesser mit den radial inneren Enden der Rippen 17,18,19,20. Bei verschiebbar ineinander gesteckten Hohlprofilen verschiedener Außendurchmesser ergeben die Innenflächen 23,24 ausreichend breite Gleitflöchen.The groove base walls of the Außenldngsnuten 13,14 lie with their inner surfaces 23,24 on the same diameter with the radially inner ends of the ribs 17,18,19,20. With hollow profiles of different outer diameters that are slidably inserted into one another the inner surfaces 23, 24 result in sufficiently wide sliding surfaces.

Die Innenlängsnuten wirken dann als Schmierstoffdepot bzw als Schmutzsammelrdume. Der-von den Innenfiöchen 23,24 und den Enden der Rippen 17,18,19,20 gebildete Durchmesser ergibt an den Enden einer Hohlprofillänge eine zylindrische Aufnahme für Einsteckteile, wobei die Profilierung eine Nachgiebigkeit für Einsteckteile mit Ubermaß bewirkt.The inner longitudinal grooves then act as a lubricant depot or as a dirt collecting space. The diameter formed by the inner fibers 23, 24 and the ends of the ribs 17, 18, 19, 20 results in a cylindrical receptacle for insert parts at the ends of a hollow profile length, wherein the profiling causes a resilience for plug-in parts with oversize.

Die Dicke der Rippen 17,18,19,20 und ihre radiale Höhe sind etwa gleich groß ausgebildet. Die Begrenzung der Innenlängsnuten sind damit fur die sichere Fixierung von Verstärkungseinschüben bei geringem Materialeinsotz ausreichend dimensioniert. Zur weiteren Optimierung des Materialverbrauches fur das Hohlprofil 11 sind benachborte Rippenpaore noch jeweils durch Zwischenlöngsnuten voneinander getrennt.The thickness of the ribs 17, 18, 19, 20 and their radial height are approximately the same great educated. The limitation of the internal longitudinal grooves are thus for the safe Fixing of reinforcement inserts with little material, nevertheless sufficiently dimensioned. To further Optimization of the material consumption for the hollow profile 11 adjacent pairs of ribs are each separated from one another by intermediate longitudinal grooves separated.

Die von den beiden Rippenpaaren 17 und 18 gebildeten InnenlangsX nuten 21 mit planparallelen Flanken liegen jeweils paarweise auf gemeinsamen Mittelebenen 25 SzwO 26, die die Mittelebene 15 im Zentrum des Hohlprofils 11 unter 45° schneiden. Die von den Rippenpaaren 19 und 20 gebildeten Innenlängsnuten 22 mit zueinander geneigten Flanken liegen auf einer gemeinsamen Mittelt ebene 27, die die Mittelebene 15 im Zentrum des Hohlprofils 11 rechtwinklig schneidet. Diese systematische Zuordnung der inneren Profilierung des Hohlprofils 11 zu den Außenlängsnuten 13,14 ergibt eine vereinfachté Weiterverarbeitung und erleichs tert die spdtere Montage einer Konstuktion aus Hohlprofilen 11.The inner longitudinal grooves formed by the two pairs of ribs 17 and 18 21 with plane-parallel flanks lie in pairs on common central planes 25 SzwO 26, which intersect the central plane 15 in the center of the hollow profile 11 at 45 °. The inner longitudinal grooves 22 formed by the pairs of ribs 19 and 20 with one another inclined flanks lie on a common median plane 27, which is the median plane 15 intersects at right angles in the center of the hollow profile 11. This systematic assignment the inner profiling of the hollow profile 11 results in the outer longitudinal grooves 13,14 a simplified further processing and facilitates the subsequent assembly of a Construction from hollow profiles 11.
