Abstract

The frame consists of a support construction with holder parts for handlebars, wheels, etc. It is formed by an open, curved, monolithic or lattice carrier, which pref. can accommodate bending loads and deform while doing so. Deformation is reduced to a minimum by the use of stiffeners. The frame is constructed from individual components, so that it can be turned to make a man's or a lady's frame. The frame may be manufactured from metal, timber, plastic, laminates and compound materials.

Description

Die Erfindung betrifft einen elastischen Rahmen entsprechend dem Oberbegriff des Anspruches 1.The invention relates to an elastic frame according to the preamble of Claim 1.

Wie bekannt, stellt der Rahmen als stützendes Element die zentrale Baugruppe eines Fahrrades dar, indem er die weiteren, für die Funktion des Gesamtsystems notwendigen Baugruppen, wie Lenkung, Räder, Antriebsmechanismus, Sattel usw. aufnimmt. Er ist üblicherweise als starres Fachwerk ausgeführt, das sowohl aus einzelnen, fest miteinander verbundenen Rohren oder mittels Muffen unlösbar verbundenen Rohrstücken besteht. Den anatomischen Besonderheiten entsprechend sind die Rahmen bei Damen-, Herren- und Kinderfahrrädern unterschiedlich gestaltet, stellen aber immer einen Starrkörper dar, dessen Verformung unerwünscht ist. Um Stöße durch Fahrbahnunebenheiten und andere Einflüsse abzufangen, sind zwischen Rahmen und Sitzfläche zum Teil sehr aufwendige und teure Federelemente eingefügt, deren Federweg aber aus konstruktiven Gründen begrenzt ist. So werden Erschütterungen auf den Führer des Fahrrades weitgehend übergeleitet. Nachteilig ist auch, daß bei unterschiedlichen Geschlechtern auch unterschiedliche Rahmen verwendet werden müssen.As is known, the frame provides the central assembly as a supporting element of a bicycle, by the other, for the function of the overall system necessary components, such as steering, wheels, drive mechanism, saddle etc. records. It is usually designed as a rigid framework, which both single, firmly connected pipes or unsolvable by means of sleeves connected pipe sections. The anatomical peculiarities the frames for women's, men's and children's bicycles are corresponding designed differently, but always represent a rigid body, the Deformation is undesirable. To bumps from bumps in the road and others Intercepting influences are sometimes very much between frame and seat Elaborate and expensive spring elements inserted, but their travel from constructive reasons is limited. So shocks to the leader of the Bicycle largely transferred. Another disadvantage is that with different Different frames must also be used for genders.

Der Erfindung liegt die Aufgabe zugrunde, eine Aufnahmemöglichkeit für vorzugsweise Fahrradbaugruppen zu schaffen, die durch elastische Verformung Stöße kompensiert und die durch einfache Umrüstungen geschlechtsspezifisch angepaßt werden kann. Erfindungsgemäß wird die Aufgabe gemäß den Kennzeichen des Hauptanspruches gelöst.The invention has for its object a recording option for preferably to create bicycle assemblies by elastic deformation Shocks are compensated for and gender-specific through simple changes can be adjusted. According to the task according to the Characteristic of the main claim solved.

Die Erfindung weist folgende Vorteile auf:
The invention has the following advantages:

  • 1. Die durch äußere Einflüsse in das Gesamtsystem eingeleitete Stoßenergie wird durch die elastische Verformung des Rahmens weitgehend kompensiert. Auf den Fahrer wirken kaum noch Stöße, sondern nur Schwingungen niedriger Frequenz mit langsam abklingender Amplitude. Diese führen zu einem angenehmen Fahrgefühl.1. The impact energy introduced into the overall system by external influences is largely compensated for by the elastic deformation of the frame. There are hardly any shocks on the driver, only vibrations lower Frequency with a slowly decaying amplitude. These lead to one pleasant driving experience.
  • 2. Durch die gebogene Form des Rahmens läßt sich eine aerodynamisch günstige und hinsichtlich der Beanspruchung des Fahrers günstige Sitzposition sehr leicht einstellen.2. The curved shape of the frame makes it aerodynamic inexpensive and favorable in terms of driver stress Adjust the seating position very easily.
  • 3. Durch einfaches Umsetzen von Baugruppen können geschlechtsspezifische Bauformen erreicht werden, wodurch eine einfachere und kostengünstigere Fertigung realisiert werden kann.3. By simply implementing assemblies, gender-specific Designs can be achieved, making it easier and less expensive Manufacturing can be realized.

Verschiedene vorteilhafte Ausführungen der erfindungsgemäßen Einrichtung sind in den Unteransprüchen angegeben. Die erfindungsgemäße Lösung wird einschließlich ihrer Funktionsweise anhand von Ausführungsbeispielen erläutert.Various advantageous designs of the device according to the invention are shown in specified in the subclaims. The solution according to the invention is inclusive their operation explained using exemplary embodiments.

Fig. 1 zeigt einen Rahmen, der aus einem c-förmigen Träger 1 besteht, dessen Ende durch zwei sich kreuzende Zugmittel 2 geschlossen wird. Damit wird erreicht, daß der Sattel 3 senkrecht zur Krümmungsebene schwingt. Über die Vorspannung der Zugmittel kann die Position des Sattels 3 gegenüber der Fahrbahn verändert werden. An den entsprechenden Stellen des Rahmens sind Aufnahmemöglichkeiten für übliche Fahrradbaugruppen wie Räder 4, ein Tretlager 5 oder Lenkung 6 sowie weitere vorgesehen. Die C-Form gewährleistet durch die offene Bauform, daß der Sattel 3 frei schwingen kann und eingeleitete Stöße vernichtet bzw. in für das Fahrgefühl angenehmere Schwingwege und Amplituden umgeformt werden. Fig. 1 shows a frame which consists of a c-shaped support 1 , the end of which is closed by two intersecting traction means 2 . This ensures that the saddle 3 swings perpendicular to the plane of curvature. The position of the saddle 3 relative to the roadway can be changed by prestressing the traction means. At the corresponding points on the frame, there are provision for conventional bicycle assemblies such as wheels 4 , a bottom bracket 5 or steering 6 and others. The open design of the C-shape ensures that the saddle 3 can swing freely and destroy impacts that have been introduced, or that they can be transformed into vibration paths and amplitudes that are more comfortable for the driver.

Entfallen die Zugmittel 2, so ist eine freie Schwingung des Sattels möglich.If the traction means 2 are omitted, the saddle can vibrate freely.

Fig. 2 zeigt einen Rahmen 7, der so gestaltet ist, daß nach geringfügigen Umbauten unterschiedliche Ausführungen (Damen- und Herrenrad) verwirklicht werden können, wie Fig. 3 zeigt. Fig. 2 shows a frame 7 , which is designed so that after minor modifications, different designs (women's and men's bike) can be realized, as shown in Fig. 3.

Fig. 4 zeigt eine Ausführungsform, bei der der Rahmen aus mehr oder weniger schwach gekrümmten Bauelementen zusammengesetzt ist. Fig. 4 shows an embodiment in which the frame is composed of more or less slightly curved components.
