Abstract

In the outer walling (2) of the profile (1), extending in the extrusion direction, are back-cut grooves (3). The grooves in the area of the outer walling are outwardly closed by separable wall strips (5) of the profile. The outer walling of the profile along the edges (13) of the wall strips are weakened formations acting as theoretical sepn. points. The outer surface of the wall strips locates firmly on the outer surface of the adjoining outer walling of the profile. The wall strips are set back in relation to the outer surface of the outer walling. The profile is of light metal, esp. aluminium alloy, plastics or of a material which permits the sepn. of the wall strips.

Description

Die Erfindung bezieht sich auf ein Strangpreßprofil für die Bildung von Gerüstkonstruktionen oder dergleichen, wie z.B. Regale, Rahmen, Möbel, Spielbaukästen und sonstige Geräte, in dessen Außenwandung sich mehrere, in Längsrichtung sich erstreckende und hinterschnitten ausgebildete Rinnen befinden.The invention relates to an extruded profile for the formation of scaffolding structures or the like, e.g. Shelves, frames, furniture, play kits and other devices, in the outer wall of which there are several channels which extend in the longitudinal direction and are undercut.

Ein solches Strangpreßprofil aus Leichtmetall ist aus der DE-OS 33 28 142 bekannt. Es weist einen etwa quadratischen Querschnitt auf, in dessen vier Außenwänden sich nach innen gehende Nuten befinden, die sich nach innen hammerkopfartig erweitern. Die Nuten werden von diagonalen Stegen begrenzt, die sich in der Mitte des Profiles an einen hohlen Profilkern anschließen, der ebenfalls quadratischen Querschnitt mit einer zylinderförmigen zentralen Bohrung besitzt.Such an extruded profile made of light metal is known from DE-OS 33 28 142. It has an approximately square cross-section, in the four outer walls of which there are inwardly extending grooves which widen inwards like a hammer head. The grooves are delimited by diagonal webs which connect to a hollow profile core in the middle of the profile, which also has a square cross-section with a cylindrical central bore.

Solche Strangpreßprofile sind dazu bestimmt, Schraubenköpfe in die hinterschnittenen Nuten aufzunehmen und dadurch ein Rahmenwerk zu bilden.Such extruded profiles are intended to accommodate screw heads in the undercut grooves and thereby form a framework.

Die Problematik solcher vorbekannten Profile besteht darin, daß an den Profilseiten, an denen keine anderen Profile befestigt werden sollen, die durchgehenden hinterschnittenen Nuten sichtbar sind und das optische Aussehen des Rahmenwerkes beeinflussen.The problem with such previously known profiles is that on the profile sides on which no other profiles are to be attached, the continuous undercut grooves are visible and influence the visual appearance of the framework.

Der Erfindung liegt hingegen die Aufgabe zugrunde, solche Profile für die Bildung von Gerüstkonstruktionen zu entwickeln, deren hinterschnittene Nuten nur an den Seiten bzw. Stellen offen sein sollen, an denen andere Profile oder Teile befestigt werden sollen, wobei eine größere Variabilität des einzelnen Profiles für mehrere Verbindungsmöglichkeiten geschaffen werden soll.The invention, however, is based on the object to develop such profiles for the formation of scaffolding structures, the undercut grooves should only be open on the sides or locations where other profiles or parts are to be attached, with greater variability of the individual profile for several connection options should be created.

Ausgehend von der DE-OS 33 28 142 besteht die erfindungsgemäße Lösung der gestellten Aufgabe darin, daß die Rinnen im Bereich der Außenwandung durch abtrennbare Wandstreifen des Profiles nach außen abgeschlossen sind, wobei die Außenwandung des Profiles längs der Ränder der Wandstreifen als Solltrennstellen dienende Wandschwächungen aufweisen.Starting from DE-OS 33 28 142, the solution of the task according to the invention is that the channels in the area of the outer wall are closed to the outside by removable wall strips of the profile, the outer wall of the profile along the edges of the wall strips having wall weaknesses serving as separation points .

Das erfindungsgemäße Profil stellt damit zunächst ein Halbzeug dar, welches nach außen abgeschlossen ist und wie ein Vollwandprofil aussieht. Lediglich die Wandschwächungen sind erkennbar und deuten an, wo sich die hinterschnittenen Nuten befinden, falls sie sich außenseitig befinden.The profile according to the invention thus initially represents a semi-finished product, which is closed to the outside and looks like a solid wall profile. Only the wall weaknesses can be seen and indicate where the undercut grooves are, if they are on the outside.

Der Vorteil dieses erfindungsgemäßen Profiles besteht darin, daß man nur denjenigen Wandstreifen abzulösen braucht, an dessen Außenwandung ein anderes Profil oder sonstiges Bauteil angeschlossen werden soll. Die anderen Wandstreifen verbleiben am Profil und vermitteln diesem im Montagezustand unter Abdeckung der hinterschnittenen Nuten einen kompakten Eindruck. Wenn sich die Notwendigkeit ergibt, andere Profile an verschiedenen Seiten des einen Profiles anzuschließen, dann werden die diesen Seiten entsprechenden Wandstreifen abgelöst.The advantage of this profile according to the invention is that you only have to replace the wall strip on the outer wall of which another profile or other component is to be connected. The other wall strips remain on the profile and give it a compact impression in the assembled state, covering the undercut grooves. If there is a need to connect other profiles on different sides of the one profile, then the wall strips corresponding to these sides are removed.

Es ist schließlich auch möglich, begrenzte Längen der Wandstreifen abzulösen, so daß oberhalb und unterhalb eines angeschlossenen Profiles oder Bauteiles die hinterschnittenen Nuten ebenfalls abgedeckt bleiben.Finally, it is also possible to remove limited lengths of the wall strips, so that the undercut grooves also remain covered above and below a connected profile or component.

Das Abtrennen von Wandstreifen aus Strangpreßprofil-Wandungen ist durch die DE-PS 27 51 622 an sich bekannt. Dort geht es darum ein Strangpreßprofil mit einem ringsum umschlossenen Hohlraum zu bilden, damit dieser Hohlraum durch einen wärmedämmenden Chemiewerkstoff ausgefüllt werden kann. Wenn dieser Chemiewerkstoff ausgehärtet ist, werden die durch Wandschwächungen begrenzten Wandstreifen von der Wandung des Strangpreßprofiles abgetrennt, so daß ein Wärme- oder Kältefluß von dem einen Profilteil zum anderen unterbrochen wird. Solche Strangpreßprofile werden zur Bildung von Rahmen für Türen, Fenstern und dergleichen eingesetzt.The separation of wall strips from extruded profile walls is known per se from DE-PS 27 51 622. There it is a question of forming an extruded profile with an all-around enclosed cavity so that this cavity can be filled with a heat-insulating chemical material. When this chemical material has hardened, the wall strips delimited by wall weaknesses are separated from the wall of the extruded profile, so that a flow of heat or cold from one profile part to the other is interrupted. Such extruded profiles are used to form frames for doors, windows and the like.

Die Anwendung der vorbekannten Technik auf die Profile nach der Gattung der Erfindung ist deswegen nicht naheliegend, weil bei der Erfindung vermieden werden muß, daß durch Abtrennung der Wandstreifen eine Instabilität des Profiles eintritt. Das erfindungsgemäße Profil bleibt vielmehr eine kompakte Einheit auch dann, wenn sämtliche Wandstreifen abgetrennt werden.The application of the known technology to the profiles according to the genus of the invention is therefore not obvious, because the invention must prevent the profile from becoming unstable by separating the wall strips. Rather, the profile according to the invention remains a compact unit even if all wall strips are cut off.

In den Unteransprüchen sind einige Ausgestaltungen der Erfindung offenbart, ohne daß dadurch der Schutzumfang der Erfindung begrenzt wird.Some embodiments of the invention are disclosed in the subclaims, without the scope of the invention being limited thereby.

So ist beim Anspruch 2 vorgesehen, daß die Außenfläche der Wandstreifen bündig zur Außenfläche der angrenzenden Außenwandung des Strangprofiles liegen. Damit gewinnt das Profil einen äußerlich glatten Eindruck. Man kann aber auch die Wandstreifen gemäß Anspruch 3 gegenüber der Außenfläche der Außenwandung erhaben oder zurückversetzt anordnen.It is provided in claim 2 that the outer surface of the wall strips are flush with the outer surface of the adjacent outer wall of the extruded profile. This gives the profile an externally smooth impression. However, the wall strips can also be raised or set back in relation to the outer surface of the outer wall.

Die erfindungsgemäßen Profile können aus Leichtmetall, insbesondere aus einer Aluminium-Legierung, aus Kunststoff oder aus einem sonstigen Werkstoff bestehen, der das Abtrennen der Wandstreifen zuläßt, ohne daß dadurch das Profil instabil wird.The profiles according to the invention can consist of light metal, in particular of an aluminum alloy, of plastic or of another material which allows the wall strips to be separated without the profile becoming unstable as a result.

Die Abstände der Wandstreifen voneinander sollten konstant bemessen sein, damit eine Geometrie in der Außenfläche des Profiles gewährleistet wird. Die Erfindung beschränkt sich aber nicht auf diese Konstanz, sondern läßt es offen, auch andere voneinander abweichende Abstände vorzusehen.The distances between the wall strips should be constant so that a geometry in the outer surface of the profile is guaranteed. However, the invention is not limited to this constancy, but leaves open the possibility of also providing other distances which differ from one another.

Gemäß Anspruch 6 kann die Lage und Ausbildung der Solltrennstellen weitgehend variiert werden.According to claim 6, the location and design of the separation points can be varied widely.

Der Querschnitt der erfindungsgemäßen Strangpreßprofile kann unterschiedlich gebildet werden. Wenn das erfindungsgemäße Profil einen prismatischen Querschnitt aufweist, erstrecken sich von dessen Eckkanten zur Profilmitte hin sich Stege, die in einen zentrisch sich erstreckenden zylindrischen und hohlen Profilkern münden. Der Profilkern der DE-OS 33 28 142 ist prismatisch und der Außenkontur des Profiles angepaßt. Wenn man hingegen entsprechend der Erfindung mit einem zylindrischen und hohlen Profilkern arbeitet, ist es möglich, die Außenwand, den Profilkern und die Stege mit gleichen Wandstarken, auch an deren Übergängen, zu bemessen, was für die Strang- oder Extruderpreßtechnik gewisse Vorteile mit sich bringt.The cross section of the extruded profiles according to the invention can be formed differently. If the profile according to the invention has a prismatic cross section, webs extend from the corner edges thereof to the profile center, which webs open into a centrally extending cylindrical and hollow profile core. The profile core of DE-OS 33 28 142 is prismatic and adapted to the outer contour of the profile. If, on the other hand, one works according to the invention with a cylindrical and hollow profile core, it is possible to dimension the outer wall, the profile core and the webs with the same wall thickness, also at their transitions, which has certain advantages for the extrusion or extrusion technology .

Die Erfindung beschränkt sich aber nicht auf die prismatische Querschnittsform des Profils, sondern offenbart auch kreisförmige oder ovale Querschnitte mit speichenförmig sich zwischen der Außenwandung und dem hohlen Profilkern erstreckenden Stegen.However, the invention is not limited to the prismatic cross-sectional shape of the profile, but also discloses circular or oval cross-sections with spoke-shaped webs extending between the outer wall and the hollow profile core.

Auch im Querschnitt dreieckige Profile sieht die Erfindung vor, wobei kleine Profile keinen hohlen Profilkern zu besitzen brauchen.The invention also provides triangular profiles in cross section, whereby small profiles need not have a hollow profile core.

Im Sinne des Anspruchs 10 kann man in der Innenwandung des hohlen Profilkerns eine oder mehrere, durchlaufend angeordnete Nuten vorsehen. Diese Nuten können nach Art von Paßfederverbindungen ein Verdrehen von in die Profilkernbohrung einschiebbaren Bolzen oder dergleichen verhindern. Andererseits kann man in solche Profilkernbohrungen Schrauben eindrehen, die in den Wandungsstegen zwischen den Nuten Schraubengänge bilden.According to claim 10, one or more continuously arranged grooves can be provided in the inner wall of the hollow profile core. In the manner of feather key connections, these grooves can prevent twisting of bolts or the like that can be inserted into the profile core bore. On the other hand, screws can be screwed into such profile core bores, which form screw threads in the wall webs between the grooves.

Schließlich ist Gegenstand der Erfindung, Profile verschiedener Querschnitte bzw. verschiedener Größe in einem Bausatz zusammenzufassen und damit die Voraussetzung zu bilden, solche Profile als Bausteine für Spielbaukästen, Do-It-Yourself-Montage oder dergleichen bereitzustellen.Finally, the object of the invention is to combine profiles of different cross sections or different sizes in a kit and thus to form the prerequisite for providing such profiles as building blocks for toy building sets, do-it-yourself assembly or the like.

Im Ausführungsbeispiel der Figur 1 ist ein Strangpreßprofil (1) aus Leichtmetall, insbesondere aus einer Aluminium-Legierung, im Querschnitt dargestellt, welches eine geschlossene Außenwandung (2) aufweist. Hinter dieser Außenwandung (2) befinden sich Rinnen (3), welche zur Aufnahme von Schraubenköpfen vorgesehen sind, wie dies aus der DE-OS 33 28 142 bekannt ist. Diese Rinnen (3) sind jedoch durch abtrennbare Wandstreifen (5) nach außen hin abgedeckt, wobei diese Wandstreifen (5) durch Wandschwächungen (14) in der Außenwandung (2) bestimmt sind, welche die Ränder (13) des abgetrennten Wandstreifens (5) bestimmen.In the exemplary embodiment in FIG. 1, an extruded profile (1) made of light metal, in particular made of an aluminum alloy, is shown in cross section, which has a closed outer wall (2). Behind this outer wall (2) there are channels (3) which are provided for receiving screw heads, as is known from DE-OS 33 28 142. However, these channels (3) are covered to the outside by detachable wall strips (5), these wall strips (5) being determined by wall weaknesses (14) in the outer wall (2) which define the edges (13) of the separated wall strip (5) determine.

Das Profil (1) kann aber auch aus Kunststoff oder aus einem sonstigen Werkstoff bestehen, der das Abtrennen der Wandstreifen (5) zuläßt, ohne daß das Profil (1) instabil wird.The profile (1) can also consist of plastic or some other material that allows the wall strips (5) to be separated without the profile (1) becoming unstable.

In Figur 2 ist gezeigt, wie ein Wandstreifen (5) zum Teil vom Profil (1) abgetrennt ist. Wenn das Profil (1) aus Leichtmetall besteht, läßt sich der wandstreifen (5) längs der Wandschwächungen (14) wie ein Reißverschluß lösen, ohne daß hierzu ein kompliziertes Werkzeug erforderlich wäre. Man braucht lediglich am Beginn bzw. am Ende des abzulösenden Wandstreifens (5) einen geringfügigen Einschnitt in die Wandschwächung (14) vorzunehmen, um dann mit einer Zange oder dergleichen den Wandstreifen (5) in der gewünschten Länge abzutrennen.FIG. 2 shows how a wall strip (5) is partially separated from the profile (1). If the profile (1) is made of light metal, the wall strip (5) can be released along the wall weakenings (14) like a zipper without a complicated tool being required for this. You only need to make a slight incision in the wall weakening (14) at the beginning or at the end of the wall strip (5) to be removed, in order to then use pliers or the like to cut off the wall strip (5) in the desired length.

Sollte es erforderlich sein, solche Wandstreifen (5) nur partiell vom Profil (1) zu lösen, wird man am Beginn und am Ende des abzutrennenden Wandstreifens (5) eine Durchtrennung der Außenwandung (2) vornehmen und danach den Wandstreifen (5) lösen.If it is necessary to only partially detach such wall strips (5) from the profile (1), the outer wall (2) will be cut through at the beginning and end of the wall strip (5) to be separated and then the wall strip (5) will be detached.

Wie die Figur 2 zeigt, wird nach dem Abtrennen des Wandstreifens (5) die hinterschnittene Rinne (3) zugänglich, welche durch vorspringende Stege (4) der Außenwandung (2) gebildet wird.As FIG. 2 shows, after the wall strip (5) has been cut off, the undercut channel (3) is accessible, which is formed by projecting webs (4) of the outer wall (2).

Die Eckkanten (6) des Profiles (1) werden innenseitig über Stege (8) mit einem hohlen Profilkern (9) verbunden, der im Querschnitt zylinderförmig ist und einen durchgehenden Hohlraum besitzt. Auf diese Weise ist es möglich, die Außenwandung (2), den Profilkern (9) und die Stege (8) mit gleichen Wanddicken auszustatten, was strangpreßtechnische Vorteile mit sich bringt.The corner edges (6) of the profile (1) are connected on the inside via webs (8) to a hollow profile core (9) which is cylindrical in cross section and has a continuous cavity. In this way it is possible the outside wall (2), the profile core (9) and the webs (8) with the same wall thicknesses, which brings extrusion advantages.

Im Beispiel der Figuren 3 bis 6 sind nun verschiedene Anwendungsfälle dargestellt, je nachdem, an welcher Seite die Wandstreifen (5) abgetrennt werden.In the example of FIGS. 3 to 6, different applications are now shown, depending on which side the wall strips (5) are cut off.

Beim Beispiel der Figur 3 wird nur ein Wandstreifen (5) abgetrennt, so daß nur eine Rinne (3) zugänglich wird. Das Profil (1) ist dann an allen anderen drei Seiten nach außen abgeschlossen.In the example of FIG. 3, only one wall strip (5) is cut off, so that only one channel (3) is accessible. The profile (1) is then closed to the outside on all other three sides.

Beim Beispiel der Figur 4 sind zwei Wandstreifen, im gezeigten Fall an gegenüberliegenden Seiten, abgetrennt. Figur 5 zeigt die Abtrennung der Wandstreifen an drei Seiten des Profiles und Figur 6 schließlich die Abtrennung der Wandstreifen (5) an allen Seiten des prismatischen bzw. quadratischen Profiles (1). Erst durch die Ausbildung des erfindungsgemäßen Profiles gemäß Figur 6 ergibt sich eine Ähnlichkeit, jedoch keine Identität, zum vorbekannten Gegenstand nach der DE-OS 33 28 142.In the example in FIG. 4, two wall strips, in the case shown on opposite sides, are separated. Figure 5 shows the separation of the wall strips on three sides of the profile and Figure 6 finally shows the separation of the wall strips (5) on all sides of the prismatic or square profile (1). It is only through the formation of the profile according to the invention according to FIG. 6 that there is a similarity, but no identity, to the previously known object according to DE-OS 33 28 142.

Figur 7 zeigt ein im Schnitt kreisförmiges Profil mit ebenfalls abtrennbaren Wandstreifen (5) und entsprechenden Wandschwächungen (14). Die Stege (8) sind speichenförmig angeordnet und schließen an einen zylindrischen hohlen Profilkern (9) an.FIG. 7 shows a profile which is circular in section with likewise removable wall strips (5) and corresponding wall weakenings (14). The webs (8) are arranged in a spoke shape and adjoin a cylindrical hollow profile core (9).

Die Figuren 8 und 9 zeigen im Querschnitt dreieckige Profile (1) mit ebenfalls von den Eckkanten (6) speichenförmig nach innen verlaufenden Stegen (8), die in einen hohlen zylindrischen Profilkern (9) münden. Wenn das Profil (1) gemäß Figur 9 im Querschnitt verhältnismäßig klein ist, kann auf den hohlen Profilkern (9) verzichtet werden, so daß die Stege (8) sich in der Mitte des Strangpreßprofiles (1) unmittelbar treffen.FIGS. 8 and 9 show in cross section triangular profiles (1) with webs (8) which also run in a spoke shape from the corner edges (6) and which open into a hollow cylindrical profile core (9). If the profile (1) according to FIG. 9 is relatively small in cross section, the hollow profile core (9) can be dispensed with, so that the webs (8) meet directly in the middle of the extruded profile (1).

Das Beispiel der Figur 10 zeigt ein im Querschnitt (12) ovales Profil (1), woraus ersichtlich ist, daß die Querschnittsform im Sinne der Erfindung beliebig gestaltet werden kann. Man kann zum Beispiel aus der ovalen Querschnittsform (12) eine birnenförmige Querschnittsgestaltung entwickeln, je nachdem, welche Gestaltungs- und Verbindungszwecke man verfolgt.The example in FIG. 10 shows a profile (1) which is oval in cross section (12), from which it can be seen that the cross-sectional shape can be designed as desired in the sense of the invention. For example, the oval cross-sectional shape (12) can be used to develop a pear-shaped cross-sectional design, depending on the design and connection purposes that are being pursued.

Die Erfindung beschränkt sich daher nicht auf die gezeigten Querschnitts-Beispiele, sondern erstreckt sich auf alle Varianten, welche von der erfindungsgemäßen Lehre abgeleitet werden können.The invention is therefore not limited to the cross-sectional examples shown, but extends to all variants which can be derived from the teaching according to the invention.

In Figur 11 ist ein Profilkern (9) vergrößert dargestellt. Er weist in der Innenwandung eine oder mehrere, durchlaufend angeordnete Nuten (15) auf, die verschiedene Aufgaben übernehmen können. Will man beispielsweise einen Bolzen in die Bohrung (16) einsetzen und diesen gegen Verdrehen sichern, kann man eine Nut (15) nach Art einer Paßfederverbindung verwenden. Man kann aber auch die zwischen den Nuten (15) verbleibenden Wandungsstege (17) zur Bildung von Gewindegängen verwenden, wenn in die Bohrung (16) Schrauben eingedreht werden sollen. Figur 12 stellt einen Systemvergleich dahingehend dar, daß die Wandstreifen (5) auch erhaben oder/und zurückversetzt gegenüber der Außenwandung (2) angeordnet werden können. Auch die Ausbildung der Solltrennstellen (14) kann gemäß Figur 13 variiert werden. Diese können an der Außen- oder/und der Innenseite der Außenwand (2) sich befinden.A profile core (9) is shown enlarged in FIG. It has one or more continuously arranged grooves (15) in the inner wall, which can perform various tasks. If, for example, you want to insert a bolt into the bore (16) and secure it against twisting, you can use a groove (15) in the manner of a feather key connection. But you can also use the remaining wall webs (17) between the grooves (15) to form threads if screws are to be screwed into the bore (16). FIG. 12 shows a system comparison in that the wall strips (5) can also be raised or / and set back with respect to the outer wall (2). The design of the predetermined separation points (14) can also be varied according to FIG. These can be located on the outside and / or inside of the outside wall (2).
