Definitions
- the invention relates to a weight frame for fitness and health devices.
- Fitness equipment is used to train athletes and health equipment to rehabilitate patients.
- the various fitness and health devices are moved depending on the type of standing, lying or sitting.
- a special device is provided for each muscle group.
- the designation of the devices is partly based on the trained muscles, partly on moving body parts, partly on the type of movement.
- the raisable and lowerable weights are guide devices or arranged in a frame.
- the preferred shape of the guide means is formed by guide rods which are held in the frame and on which the weights slide.
- the weights are moved by traction means.
- pulling means serve ropes, chains and bands.
- the traction means connect the weights with moving machine parts or are operated directly by hand.
- the exercises then run against the resistance of the weights.
- weight packages which can be coupled with the traction means as desired, so that the resistance can be adjusted by changing the number of weights.
- the frame parts are referred to with the raisable and lowerable weights as a weight frame.
- the weight frame above have connection surfaces for a cross-beam and optionally for a top plate as the upper connecting element

In itself, it would be obvious, after knowledge of the relationship between comfort and vibration resistance by additional supports or struts to effect a stiffening of the machine frame or equipment frame. It is also known to go another way. From the EP-A-0965365 It is known to manufacture weight frames from oval profiles, which can also be designed as elliptical profiles. Here, the weight frame is formed by an arc that frames the raised and lowered weights with the associated guide rods. This proposal goes with the elliptical profile another way.

- Compared to the arch construction results in significant structural advantages and significant savings.
- the additional expense of the construction according to the invention compared to the use of rectangular profiles much more bearable than expected.
- the invention is not diminished by the fact that from the US-PS 3971555 Machines are known with a weight frame, which consists of straight, parallel profiles, which are connected together above a top plate.
- profiles with the cross section of an ellipse and preferably with the following dimensions are used for supports and struts of the machine frame 150mm (largest external dimension) to 75mm (smallest external dimension) or 120mm to 60mm or 100mm to 50mm or 80mm to 40mm or 60mm to 30mm. It is important to distinguish between the dimensional tolerances and other nominal dimensions.
- the dimensional tolerances are at most equal to the possible thickness of a weld when welding profiles, preferably the dimensional tolerance is at most 4mm, more preferably at most 3mm.

- the smaller profile is centered on the narrow side of the larger profile and is the narrow side of the smaller profile in the projection on the narrow side of the larger profile exactly parallel or aligned with the longitudinal axis of the larger profile.
- the outer dimension of the smaller profile is smaller than the narrow side of the larger profile.
- the angular position of the smaller profile can vary to the larger profile. This applies both to the circumferential angle of the larger profile and to the angle to the plane in which the broad side or the narrow side of the larger profile is located.
- the shocks according to the invention can be produced by introducing a bore with the contour of the smaller profile into the larger profile.
- the contour can easily be produced with a computer-controlled milling cutter.
- the end surface / contact surface of the smaller profile can be adapted to the respective curvature of the contact surface of the larger profile.
- the adjustment can be made as above with the aid of a computer-controlled milling cutter.
- the smaller profile can be brought there without injury to the outer surface of the larger profile to the plant without a gap forms, the opening width is greater than the allowable for the welding measure.

- opening gaps in welding can be closed when the material edges are approximated with a build-up weld until they can be closed with a last weld.
- the build-up welding can be carried out continuously at the material edges or back and forth at individual edge points. In this case, a welding operation in smaller and / or larger steps is possible, in which by means of reciprocating welding, a connection between the material edges are generated.
- the procedure according to the invention includes that for larger dimensional differences between the external dimensions of the profiles, straight end cuts for the connection surfaces of the smaller profiles are also used. The resulting gaps can be bridged with simple welds.

- the upstanding profile can occupy different rotational positions / angular positions relative to the continuous profile compared to the continuous profile.
- Miter cuts are provided on the joints.
- freedom of choice between miter cut and handling exists as a continuous profile with a raised profile. This situation exists when one profile covers and does not go beyond the entire face of the upstanding profile.
- the bending is then carried out by separation at the intended Abwinkelstelle and reconnecting after preparation of the profile ends.
- the profile ends are mitred so that then can be produced a welded joint.
- the bending is preferably carried out with jaws, between which the profile is clamped and which are then pivoted against each other.

Description
Die Erfindung betrifft ein Gewichtsrahmen für Fitneß- und Gesundheitsgeräte.The invention relates to a weight frame for fitness and health devices.
Fitneßgeräte dienen zum Training von Sportlern, Gesundheitsgeräte zur Rehabilitation von Patienten. Die verschiedenen Fitneß- und Gesundheitsgeräte werden je nach Bauart stehend, liegend oder sitzend bewegt. Vorzugsweise ist für jede Muskelgruppe ein besonderes Gerät vorgesehen. Die Bezeichnung der Geräte orientiert sich teilweise an den trainierten Muskeln, teilweise an bewegten Körperteilen, teilweise an der Art der Bewegung.Fitness equipment is used to train athletes and health equipment to rehabilitate patients. The various fitness and health devices are moved depending on the type of standing, lying or sitting. Preferably, a special device is provided for each muscle group. The designation of the devices is partly based on the trained muscles, partly on moving body parts, partly on the type of movement.
Bis auf Ausnahmen wird der Bewegung bei den bekannten Geräten mit Hilfe heb- und senkbarer Gewichte eine Widerstand entgegengesetzt. Die heb- und senkbaren Gewichte sind Führungseinrichtungen bzw. in einem Rahmen angeordnet. Die bevorzugte Form der Führungseinrichtung wird durch Führungsstangen gebildet, die in dem Rahmen gehalten werden und auf denen die Gewichte gleiten.Except for exceptions, the movement in the known devices with the help of raisable and lowerable weights opposed to a resistance. The raisable and lowerable weights are guide devices or arranged in a frame. The preferred shape of the guide means is formed by guide rods which are held in the frame and on which the weights slide.
Die Gewichte werden über Zugmittel bewegt. Als Zugmittel dienen Seile, Ketten und Bänder. Die Zugmittel verbinden die Gewichte mit bewegten Maschinenteilen oder werden unmittelbar von Hand betätigt.The weights are moved by traction means. As pulling means serve ropes, chains and bands. The traction means connect the weights with moving machine parts or are operated directly by hand.
Die Übungen verlaufen dann gegen den Widerstand der Gewichte. Üblicherweise handelt es sich um Gewichtspakete, die nach Wahl mit dem Zugmittel gekoppelt werden können, so daß der Widerstand durch Veränderung der Anzahl der Gewichte einstellbar ist.The exercises then run against the resistance of the weights. Usually these are weight packages which can be coupled with the traction means as desired, so that the resistance can be adjusted by changing the number of weights.
Im folgenden werden die Rahmenteile mit den heb- und senkbaren Gewichten als Gewichtsrahmen bezeichnet.In the following, the frame parts are referred to with the raisable and lowerable weights as a weight frame.
Die Gewichtsrahmenteile finden sich in diversen Fitneß- und Gesundheitsmaschinen als Maschinenbestandteil bzw. Maschinenrahmen. Zu den bekannten Maschinen gehören:

Nach einem bekannten Vorschlag besitzen die Gewichtsrahmen oben Anschlußflächen für eine Quertraverse und gegebenenfalls für eine Kopfplatte als oberes Verbindungselement Die Quertraverse dient der Abstandsbildung für die Kabelzugstation und die Kopfplatte als stabile Verbindung in der Verwendung für die Doppelstation. Dabei ergänzen sich die Kopfplatte und die oberen Anschlußflächen der Gewichtsrahmen in idealer Weise. Vorzugsweise ist die Quertraverse mit einem Anschlußflansch versehen, der die Oberseite der Gewichtsrahmen ganz oder teilweise überdeckt, so daß die gleiche Verbindung wie bei der Kopfplatte möglich wird.According to a known proposal, the weight frame above have connection surfaces for a cross-beam and optionally for a top plate as the upper connecting element The cross-beam is the distance formation for the cable tensioning station and the top plate as a stable connection in the use of the dual station. In this case, the top plate and the upper pads of the weight frame complement each other in an ideal way. Preferably, the cross-beam is provided with a connecting flange, which covers the top of the weight frame in whole or in part, so that the same connection as in the top plate is possible.
Unten sind die Gewichtsrahmen wahlweise mit einem U-förmigen oder einem T-formigen oder T-förmigen Fuß versehen.Below, the weight frames are optionally provided with a U-shaped or a T-shaped or T- shaped foot.
Außerdem ist bei Verwendung einer unteren Traverse auch unten eine Schraubverbindung bekannt.In addition, when using a lower cross member also below a screw is known.
Damit ergeben sich nicht nur Rationalisierungsvorteile in der Fertigung und Vorratshaltung sondern auch Transportvorteile. Das Transportvolumen kann durch Zusammenlegen der Maschinen drastisch reduziert werden. Außerdem sind die Geräte beim Transport wesentlich leichter zu handhaben.This results in not only rationalization advantages in production and stockpiling but also transport advantages. The transport volume can be drastically reduced by merging the machines. In addition, the devices are much easier to handle during transport.
Die Gewichtsrahmen sind Bestandteil der Geräte.The weight frames are part of the devices.
Andere Bestandteile sind zum Beispiel schwenkbare Hebel, Sitze, Rückenlehnen.Other components include, for example, pivoting levers, seats, backrests.
Die Hebel, Sitze und Rückenlehnen bedürfen einer Lagerung und Halterung. Die Halterung erfolgt durch den Maschinenrahmen oder Geräterahmen. Der Gewichtsrahmen kann durch Verbindung mit den die Halterung bildenden Teilen zum Maschinenrahmen werden. Zumindest ergänzt der Gewichtsrahmen den Maschinenrahmen.The levers, seats and backrests require storage and mounting. The holder is made by the machine frame or equipment frame. The weight frame can become the machine frame by connection with the parts forming the holder. At least the weight frame complements the machine frame.
Die bekannten Gewichtsrahmen bestehen in der Regel aus einem Hohlprofil.The known weight frame usually consist of a hollow profile.
Ganz überwiegend finden Profile mit rechteckförmigem Querschnitt Anwendung, die miteinander verschweißt werden. Selten finden Profile mit rundem Querschnitt oder ovalem Querschnitt Anwendung. Die rechteckförmigen Profile sind in der Herstellung komplizierter als ein Rundprofil, auch komplizierter als die Herstellung von Profilen mit ovalen Querschnitten, die vorzugsweise durch Stauchen von Rundprofilen entstehen.Most predominantly find profiles with rectangular cross-section application, which are welded together. Rarely find profiles with round cross section or oval cross section application. The rectangular profiles are more complicated to manufacture than a round profile, also more complicated than the production of profiles with oval cross sections, which are preferably produced by upsetting round profiles.
Es ergeben sich aber in der Anwendung der rechteckförmigen Profile erhebliche Vorteile. Die Vorteile liegen in den Anschlüssen der Profile, insbesondere in den Stößen zwischen Streben und Stützen. Das vor allem dann, wenn Profile mit unterschiedlichen Größenabmessungen gestoßen werden müssen. Vor diesem Hintergrund finden derzeit fast ausschließlich Profile mit rechteckförmigem Querschnitt Anwendung. Maschinen mit Rechteckprofilen sind zum Beispiel aus der
Wie oben erläutert, haben sich die Profile bewährt.As explained above, the profiles have proven themselves.
Gleichwohl hat sich die Erfindung die Aufgabe gestellt die Profile zu verbessern.Nevertheless, the invention has the task of improving the profiles.
Dabei wendet sich die Erfindung gemäß Anspruch 1 einem Profil mit dem Querschnitt einer Ellipse zu, das im Vergleich zu rechteckförmigen Profilquerschnitten einen extrem hohen Anwendungsaufwand zur Folge hat.In this case, the invention according to claim 1 turns to a profile with the cross section of an ellipse, which has an extremely high application cost compared to rectangular profile cross sections.
Die Bedeutung der Festigkeitswerte ist nicht ohne weiteres ersichtlich, weil die herkömmlichen Profile üblicherweise überdimensioniert sind.The importance of the strength values is not readily apparent because the conventional profiles are usually oversized.
Die Erfindung hat jedoch erkannt, daß es nicht allein auf die bloße Festigkeit gegen Bruch oder gegen bleibende Verformung ankommt. Die Erfindung hat erkannt, daß die Schwingung der Maschine Einfluß auf den Benutzer hat. Je schwingungsstabiler die Konstruktion ist, desto größer ist das Komfortgefühl des Benutzers. An sich wäre es naheliegend, nach Kenntnis des Zusammenhanges zwischen Komfortgefühl und Schwingungsfestigkeit durch zusätzliche Stützen oder Streben eine Versteifung des Maschinenrahmens bzw. Geräterahmens zu bewirken. Es ist auch bekannt, einen anderen Weg zu gehen. Aus der
Die Erfindung hält gleichwohl an den Profilen mit dem Querschnitt einer Ellipse fest.The invention nonetheless retains the profiles with the cross-section of an ellipse.
Nach der Erfindung wird der Aufwand dadurch ganz erheblich reduziert, daß anstelle der gebogenen Profile für den Gewichtsrahmen nur gerade Profile als seitliche Stützen Anwendung finden und daß die seitlichen Stützen durch eine Kopfplatte/Traverse miteinander verbunden sind. Dabei soll eine Schweißverbindung Anwendung finden.According to the invention, the effort is considerably reduced by the fact that only straight profiles are used as lateral supports instead of the curved profiles for the weight frame and that the lateral supports are interconnected by a head plate / traverse. It should find a weld application.
Zugleich löst sich die Erfindung von den bekannten Steckverbindungen und kehrt die Erfindung zurück zu den Verbindungstechniken bzw. Anschlußtechniken, welche von den Rechteckprofilen bekannt sind. Gegenüber der Bogenkonstruktion ergeben sich deutliche bauliche Vorteile und erhebliche Einsparungen. Überraschenderweise ist der Mehraufwand der erfindungsgemäßen Bauweise gegenüber der Anwendung von Rechteckprofilen viel erträglicher als erwartet.At the same time, the invention detaches itself from the known connectors and returns the invention to the joining techniques known from the rectangular profiles. Compared to the arch construction results in significant structural advantages and significant savings. Surprisingly, the additional expense of the construction according to the invention compared to the use of rectangular profiles much more bearable than expected.
Die Erfindung wird nicht dadurch geschmälert, daß aus der
Wie bereits oben ausgeführt, ist es für einen Durchschnittsfachmann wegen der zu erwartenden Anwendungsschwierigkeiten nicht nahe liegend, die Rechteckprofile durch Ellipsenprofile zu ersetzen.As already stated above, it is not obvious for a person of ordinary skill in the art to replace the rectangular profiles by elliptical profiles because of the expected application difficulties.

Nach der Erfindung werden für Stützen und Streben des Maschinenrahmens Profile mit dem Querschnitt einer Ellipse und vorzugsweise mit folgenden Abmessungen verwendet 150mm (größtes Außenmaß) zu 75mm (kleinstes Außenmaß) oder 120mm zu 60mm oder 100mm zu 50mm oder 80mm zu 40mm oder 60mm zu 30mm. Dabei ist zu unterscheiden zwischen den Maßtoleranzen und anderen Nennmaßen. Die Maßtoleranzen sind höchstens gleich der möglichen Dicke einer Schweißnaht beim Verschweißen von Profilen, vorzugsweise ist die Maßtoleranz höchstens 4mm, noch weiter bevorzugt höchstens 3mm.According to the invention, profiles with the cross section of an ellipse and preferably with the following dimensions are used for supports and struts of the machine frame 150mm (largest external dimension) to 75mm (smallest external dimension) or 120mm to 60mm or 100mm to 50mm or 80mm to 40mm or 60mm to 30mm. It is important to distinguish between the dimensional tolerances and other nominal dimensions. The dimensional tolerances are at most equal to the possible thickness of a weld when welding profiles, preferably the dimensional tolerance is at most 4mm, more preferably at most 3mm.
Die Nennmaße weichen in anderen Abmessungen höchstens um 10%, vorzugsweise höchstens um 5%, von den oben angegebenen Nennmaßen/Außenmaßen ab.The nominal dimensions deviate in other dimensions at most by 10%, preferably at most by 5%, from the nominal dimensions / external dimensions given above.
Die Wandungsdicke der erfindungsgemäßen Rohre ist vorzugsweise höchstens 6mm, noch weiter bevorzugt 5mm und höchst bevorzugt 4mm.The wall thickness of the tubes according to the invention is preferably at most 6 mm, more preferably 5 mm and most preferably 4 mm.
Die Rohrstöße kommen in unterschiedlichen Formen vor. Dabei unterscheidet die Erfindung zwischen den Stößen von Rohrprofilen gleicher Abmessungen und den Stößen von Rohrprofilen ungleicher Abmessungen.The pipe joints come in different forms. The invention distinguishes between the joints of pipe profiles of the same dimensions and the joints of pipe profiles of unequal dimensions.
Bei den Stößen von Rohrprofilen ungleicher Abmessungen wird zwischen drei Grundmustern und Abwandlungen von diesen Grundmustern unterschieden. Die Grundmuster gehen jeweils von einem durchgehenden größeren Profil und einem an das durchgehende größere Profil anschließenden kleineren Profil aus.In the joints of pipe profiles of unequal dimensions, a distinction is made between three basic patterns and modifications of these basic patterns. The basic patterns are each based on a continuous larger profile and a subsequent to the continuous larger profile smaller profile.
Durchgehend ist ein Profil nicht nur dann, wenn es um ein wesentliches Maß gegenüber dem aufstehenden Profil übersteht. Durchgehend im Sinne der Erfindung ist ein Profil bereits dann, wenn es die ganze Stirnfläche des aufstehenden Profiles überdeckt.Throughout is a profile not only when it survives to a significant degree compared to the upstanding profile. Throughout the meaning of the invention is a profile already when it covers the entire face of the upstanding profile.
Die Lage der kleineren Profile am größeren Profil wird bestimmt durch die Längsachse der Profile, durch die Lage der Schmalseite und durch die Lage der Breitseite. Als Breitseite wird im folgenden die Seitenansicht des Profiles bezeichnet, in der das Profil das größte Außenmaß zeigt. Als Schmalseite wird im folgenden die Seitenansicht des Profiles bezeichnet, in der das Profil das kleinste Außenmaß zeigt.The location of the smaller profile on the larger profile is determined by the longitudinal axis of the profiles, by the position of the narrow side and by the position of the broadside. As broadside, the side view of the profile is referred to below, in which the profile shows the largest external dimensions. As a narrow side, the side view of the profile is referred to below, in which the profile shows the smallest external dimensions.
Bei allen Grundmustern steht das kleinere Profil senkrecht auf dem Außenmantel des größeren Profils.For all basic patterns, the smaller profile is perpendicular to the outer shell of the larger profile.
Bei den Grundmustern A und B steht das kleinere Profil mittig auf der Breitseite des größeren Profils. Beim Grundmuster A verläuft die Breitseite des kleineren Profils in der Projektion auf die Breitseite des größeren Profils genau 90 Grad quer zur Längsachse des größeren Profils. Beim Grundmuster B verläuft die Breitseite des kleineren Profils in der Projektion auf die Breitseite des größeren Profils genau parallel bzw. fluchtend zur Längsachse des größeren Profils.In the basic patterns A and B, the smaller profile is centered on the broad side of the larger profile. In the basic pattern A, the broad side of the smaller profile in the projection on the broad side of the larger profile runs exactly 90 degrees transverse to the longitudinal axis of the larger profile. In the basic pattern B, the broad side of the smaller profile in the projection runs on the broad side of the larger profile exactly parallel or in alignment with the longitudinal axis of the larger profile.
Bei dem Grundmuster C steht das kleinere Profil mittig auf der Schmalseite des größeren Profils und steht die Schmalseite des kleineren Profils in der Projektion auf der Schmalseite des größeren Profils genau parallel bzw. fluchtend zur Längsachse des größeren Profils auf. Vorzugsweise ist das Außenmaß des kleineren Profils dabei kleiner als die Schmalseite des größeren Profils.In the basic pattern C, the smaller profile is centered on the narrow side of the larger profile and is the narrow side of the smaller profile in the projection on the narrow side of the larger profile exactly parallel or aligned with the longitudinal axis of the larger profile. Preferably, the outer dimension of the smaller profile is smaller than the narrow side of the larger profile.
In den Abwandlungen der Grundmuster kann die Winkelstellung des kleineren Profiles zum größeren Profil variieren. Das gilt sowohl für den Umfangswinkel des größeren Profils als auch für den Winkel zur Ebene, in der die Breitseite bzw. die Schmalseite des größeren Profiles liegt.In the modifications of the basic pattern, the angular position of the smaller profile can vary to the larger profile. This applies both to the circumferential angle of the larger profile and to the angle to the plane in which the broad side or the narrow side of the larger profile is located.
Die erfindungsgemäßen Stöße können dadurch hergestellt werden, daß in das größere Profil eine Bohrung mit der Kontur des kleineren Profils eingebracht wird. Die Kontur läßt sich mit einem EDV-gesteuerten Fräser ohne weiteres herstellen.The shocks according to the invention can be produced by introducing a bore with the contour of the smaller profile into the larger profile. The contour can easily be produced with a computer-controlled milling cutter.
Alternativ kann die Stirnfläche/Berührungsfläche des kleineren Profiles der jeweiligen Wölbung der Berührungsfläche des größeren Profiles angepaßt werden. Die Anpassung kann wie oben mit Hilfe eines EDV-gesteuerten Fräsers erfolgen. Durch die Anpassung kann das kleinere Profil ohne Verletzung der Mantelfläche des größeren Profiles dort zur Anlage gebracht werden, ohne daß sich ein Spalt bildet, dessen Öffnungsweite größer als das für die Schweißung zulässige Maß ist. Das Öffnungsweite ist bei normaler Schweißnaht höchstens gleich 75% der normalen Schweißnahtbreite, vorzugsweise höchstens 50% und noch weiter bevorzugt höchstens gleich 25% der normalen Schweißnahtbreite. Die normale Schweißnahtbreite ist die übliche Schweißnahtbreite bei schließend aneinander liegenden Flächen von größerem und kleinerem Profil. Vorzugsweise handelt es sich bei der üblichen Schweißnahtbreite um eine genormte Schweißnahtbreite, noch weiter bevorzugt um DIN-Schweißnahtbreiten.Alternatively, the end surface / contact surface of the smaller profile can be adapted to the respective curvature of the contact surface of the larger profile. The adjustment can be made as above with the aid of a computer-controlled milling cutter. By adjusting the smaller profile can be brought there without injury to the outer surface of the larger profile to the plant without a gap forms, the opening width is greater than the allowable for the welding measure. The opening width is at normal weld seam at most equal to 75% of the normal weld width, preferably at most 50% and even more preferably at most equal to 25% of the normal weld width. The normal Weld seam width is the usual weld seam width for closing surfaces of larger and smaller profiles. Preferably, the usual weld seam width is a standardized weld seam width, more preferably DIN weld seam widths.
In besonderen Fällen ist die Öffnungsweite des Spaltes zwischen dem größeren und kleineren Profile auch bei gerader Stirnfläche des kleineren Profiles gering genug, um mit üblicher Schweißnaht eine gewünschte Schweißverbindung zu erzeugen. Das ist der Fall bei größeren Abmessungsunterschieden zwischen den Rohren und insbesondere dann, wenn das kleinere Profil auf der Breitseite des größeren Profils aufsteht.In special cases, the opening width of the gap between the larger and smaller profiles, even with a straight face of the smaller profile is low enough to produce a desired weld with conventional weld. This is the case with larger dimensional differences between the tubes and especially when the smaller profile rests on the broad side of the larger profile.
Wahlweise lassen sich auch größere Öffnungsspalten beim Schweißen schließen, wenn die Materialränder mit einer Auftragsschweißung einander angenähert werden, bis sie mit einer letzten Schweißnaht geschlossen werden können. Die Auftragsschweißung kann kontinuierlich umlaufend an den Materialrändern oder hin- und hergehend an einzelnen Randstellen erfolgen. Dabei ist ein Schweißbetrieb in kleineren und/oder größeren Schritten möglich, in denen durch hin- und hergehendes Schweißen eine Verbindung zwischen den Materialrändern erzeugt werden.Optionally, even larger opening gaps in welding can be closed when the material edges are approximated with a build-up weld until they can be closed with a last weld. The build-up welding can be carried out continuously at the material edges or back and forth at individual edge points. In this case, a welding operation in smaller and / or larger steps is possible, in which by means of reciprocating welding, a connection between the material edges are generated.
Die erfindungsgemäße Verfahrensweise schließt ein, daß bei größeren Abmessungsunterschieden zwischen den Außenmaßen der Profile auch gerade Stirnschnitte für die Anschlußflächen der kleineren Profile Anwendung finden. Dabei sind die sich ergebenden Spalte mit einfachen Schweißnähten überbrückbar.The procedure according to the invention includes that for larger dimensional differences between the external dimensions of the profiles, straight end cuts for the connection surfaces of the smaller profiles are also used. The resulting gaps can be bridged with simple welds.
Größere Abmessungsunterschiede liegen dann vor, wenn die sich ergebenden Spalte zwischen dem kleineren Profil und dem größeren Profil in dem oben beschriebenen Rahmen liegen.Larger dimensional differences are present when the resulting gaps between the smaller profile and the larger profile are in the frame described above.
Spalte können sich bei geradem Stirnschnitt an den Profilen auch dadurch ergeben, daß die Profile bei der Verbindung zu einem Rahmen mit geneigten Stützen als Traversen unter einem Winkel auf den Stützen aufstehen, der von 90 Grad abweicht.Columns can also result in a straight end cut on the profiles in that the profiles stand up when connecting to a frame with inclined columns as trusses at an angle on the supports, which deviates from 90 degrees.
Neben den Verbindungen ungleicher Profile kommen auch Verbindungen gleicher Profile in Betracht. Für die Verbindung gleicher Profile kommen die oben beschriebenen Grundmuster A bis C in Betracht. Jedoch ist nach der Erfindung in allen Abwandlungen vorgesehen, daß das auf dem durchgehenden Profil aufstehende Profil seitlich nicht über den Rand des durchgehenden Profiles übersteht. Dabei kann das durchgehende Profil verschiedene Drehstellungen/Winkelstellungen gegenüber dem aufstehenden Profil einnehmen. Desgleichen kann das aufstehende Profil gegenüber dem durchgehenden Profil verschiedene Drehstellungen/Winkelstellungen gegenüber dem durchgehenden Profil einnehmen. Soweit die Bedingung des nicht überstehenden Randes eingehalten wird, ergibt sich die gleiche Situation wie oben zu den unterschiedlichen Profilen beschrieben.In addition to the compounds of unequal profiles and compounds of the same profile come into consideration. For the connection of the same profiles, the basic patterns A to C described above come into consideration. However, it is provided according to the invention in all modifications that the standing on the continuous profile profile does not laterally beyond the edge of the continuous profile. The continuous profile can take different rotational positions / angular positions relative to the upstanding profile. Likewise, the upstanding profile can occupy different rotational positions / angular positions relative to the continuous profile compared to the continuous profile. As far as the condition of the non-protruding edge is maintained, the same situation arises as described above for the different profiles.
Bei der Verbindung gleicher Profile kommen auch Stöße zwischen Rohrenden vor.When connecting the same profile also impacts between pipe ends occur.
Dabei haben die durch die Schmalseiten verlaufenden Mittelachsen oder die durch die Breitseiten verlaufenden Mittelachsen beider Profile parallel zueinander.In this case, extending through the narrow sides of the central axes or extending through the broad sides of the central axes of both profiles parallel to each other.
An den Stößen sind Gehrungsschnitte vorgesehen. In einer Situation besteht Wahlfreiheit zwischen dem Gehrungsschnitt und der Handhabung als durchgehendes Profil mit einem aufstehenden Profil. Diese Situation ist gegeben, wenn das eine Profil die gesamte Stirnfläche des aufstehenden Profils überdeckt und nicht darüber hinausgeht.Miter cuts are provided on the joints. In one situation, freedom of choice between miter cut and handling exists as a continuous profile with a raised profile. This situation exists when one profile covers and does not go beyond the entire face of the upstanding profile.

Sowohl der Anschluß der Stützen und Streben und Füße bedingt Verbindungen gleicher und unterschiedlicher Profile, wie sie oben beschrieben sind.Both the connection of the supports and struts and feet requires connections of the same and different profiles, as described above.
Die Verbindung von Profilen kommt auch beim Abwinkeln von Stützen oder Streben oder Hebeln oder Füßen vor. Das gilt zum Beispiel für

Das Abwinkeln erfolgt dann durch Trennung an der vorgesehenen Abwinkelstelle und erneutes Verbinden nach Vorbereitung der Profilenden. Die Profilenden werden dabei auf Gehrung geschnitten, so daß sich anschließend eine Schweißverbindung herstellen läßt.The bending is then carried out by separation at the intended Abwinkelstelle and reconnecting after preparation of the profile ends. The profile ends are mitred so that then can be produced a welded joint.
Anstelle der Abwinkelung durch Trennung und erneutes Verbinden kann auch eine Abwinkelung durch Biegung erfolgen.Instead of the bending by separation and reconnection can also be a bend by bending.
Die Biegung erfolgt vorzugsweise mit Backen, zwischen denen das Profil eingespannt wird und die danach gegeneinander verschwenkt werden. Bei der Biegung wird das Profil vorzugsweise nur so gebogen, daß die mit der Biegung entstehende Verformung an der Biegestelle zu Festigkeitswerten führt, die höchstens 25% geringer als die Festigkeit einer oben beschriebenen Schweißverbindung ist, und vorzugsweise gleich oder besser als die Festigkeit einer oben beschriebenen Schweißverbindung ist.The bending is preferably carried out with jaws, between which the profile is clamped and which are then pivoted against each other. In bending, the profile is preferably bent only so that the deflection resulting at the bend results in strength values that is at most 25% less than the strength of a welded joint described above, and preferably equal to or better than the strength of one described above Welded joint is.
Die Qualität der Verformung wird wesentlich durch den Biegeradius und dadurch bestimmt, inwieweit die Biegeachse parallel zur Flachseite des Profiles (flach wird gebogen) oder parallel zur Schmalseite des Profiles (hochkant wird gebogen) verläuft und wie weit die Biegung verläuft und wie dick die Profilwandung ist.The quality of the deformation is essentially determined by the bending radius and the extent to which the bending axis parallel to the flat side of the profile (flat is bent) or parallel to the narrow side of the profile (upright is bent) runs and how far the bend runs and how thick the profile wall ,
Wenn ein Profil mit einer Wandungsdicke von 3 bis 5 mm flach bis zu 90 Grad gebogen wird, ist der mittlere Biegeradius mindestens gleich dem größten Profilaußenmaß, vorzugsweise mindestens gleich dem 1,25fachen des größten Profilaußenmaßes und noch weiter bevorzugt mindestens gleich dem 1,5fachen des größen Profilaußenmaßes. Bei einem Profil mit einem größten Außenmaß von 120 mm ergibt sich dadurch bei einer Biegung eines 90 Grad-Winkels mindestens ein mittlerer Biegeradius von 120mm, vorzugsweise ein mittlerer Biegeradius von mndestens 150mm und noch weiter bevorzugt ein mittlerer Biegeradius von mindestens 180mm. Dabei ist der sich an der Mittellinie des Profiles ergebende Biegeradius der mittlere Biegeradius.If a profile with a wall thickness of 3 to 5 mm is bent flat up to 90 degrees, the mean bending radius is at least equal to the largest profile external dimension, preferably at least equal to 1.25 times the largest profile external dimension and even more preferably at least 1.5 times the size of the external profile. For a profile with a maximum external dimension of 120 mm, this results in a bending of a 90 degree angle at least a mean bending radius of 120mm, preferably a mean bending radius of at least 150mm and even more preferably a mean bending radius of at least 180mm. Here, the resulting at the center line of the profile bending radius of the mean bending radius.
Wenn ein Profil mit einer Wandungsdicke von 3 bis 5 mm hochkant bis zu 90 Grad gebogen wird, ist der mittlere Biegeradius mindestens gleich dem 3fachen des größten Profilaußenmaßes, vorzugsweise mindestens gleich dem 3,5fachen des größten Profilaußenmaßes und noch weiter bevorzugt mindestens gleich dem 4fachen des größen Profilaußenmaßes. Bei einem Profil mit einem größten Außenmaß von 120 ergibt sich dadurch bei einer Biegung eines 90 Grad-Winkels ein mittlerer Biegeradius von mindestens 360mm, vorzugsweise ein mittlerer Biegeradius von mindestens 420 mm und noch weiter bevorzugt von mindestens 480 mm. Dabei ist der sich an der Mittellinie des Profiles ergebende Biegeradius der mittlere Biegeradius.If a profile with a wall thickness of 3 to 5 mm is bent upright up to 90 degrees, the mean bending radius is at least equal to 3 times the largest profile external dimension, preferably at least equal to 3.5 times the largest profile external dimension and even more preferably at least 4 times that sizes profile external dimension. For a profile with a maximum external dimension of 120, this results in a bending of a 90 degree angle, a mean bending radius of at least 360mm, preferably a mean bending radius of at least 420 mm and even more preferably of at least 480 mm. Here, the resulting bending radius at the center line of the profile is the mean bending radius.
