Description

Heimtrainer mit einer Drehmechanik Exercise bike with a rotating mechanism
Die Erfindung betrifft einen Heimtrainer mit einer Drehmechanik, die von einem Benutzer im Sitzen oder Liegen mit den Füßen betätigbar ist, mit einem die Drehmechanik aufweisenden Hauptgestell, das einen Stützfuß zur Abstützung des Hauptgestells am Boden und eine Sattelhalterung für einen Sattel aufweist, auf dem der Benutzer sitzen kann, wenn er den Heimtrainer als stationäres fahrradahnlich.es Trainings- gerät verwendet, und mit einem Zusatzgestell, das einen Stützfuß zur Abstützung des Zusatzgestells am Boden, ein Verbindungsteil zum Anschluß an das Hauptgestell und einen Sitz mit Rückenlehne aufweist, auf dem der Benutzer sitzen kann, wenn er den Heimtrainer als stationäres liegefahrrad- ähnliches Trainingsgerät verwendet.The invention relates to an exercise bike with a rotating mechanism that can be operated by a user while sitting or lying down with the feet, with a rotating mechanism main frame, which has a support leg for supporting the main frame on the ground and a saddle holder for a saddle on which the User can sit if he uses the exercise bike as a stationary bicycle-like training device, and with an additional frame, which has a support foot to support the additional frame on the floor, a connecting part for connection to the main frame and a seat with backrest on which the User can sit when he uses the exercise bike as a stationary exercise bike-like exercise bike.
Ein derartiger Heimtrainer, der sowohl als stationäres fahrradähnliches Trainingsgerät als auch als stationäres liegefahrradahnlich.es Trainingsgerät verwendet werden kann, ist aus der DE-OS 26 52 892 bekannt. Bei diesem Heimtrainer ist das Zusatzgestell für den liegefahrradähnlichen Betrieb entweder an einen hinteren Stützfuß des Hauptgestells oder an ein den hinteren Stützfuß haltendes Gestellteil des Hauptgestells angeschlossen. Die Drehmechanik ist höhenverstellbar, um für die Benutzung des Heimtrainers als fahrradähnliches oder liegefahrradähnliches Trainingsgerät die jeweils günstigste Bodenfreiheit der Fußpedale der Drehmechanik erzielen zu können. Wird der Heimtrainer als fahrradähnliches Trainingsgerät benutzt, ist es günstig, wenn die Drehmechanik in der Nähe des Bodens ist, um dem Benutzer den Auf- und Abstieg auf bzw. von dem Sattel des Heimtrainers bequem zu machen, wobei eine bodennahe Anordnung der Drehmechanik wegen der relativ aufrechten Sitzhaltung des Benutzers und der daraus resultierenden im wesentlichen horizontalen Stellung der Füße auf den Pedalen der Drehmechanik ein störender Kontakt der Füße oder der Beine des Benutzers mit dem Boden nicht auftreten kann. Wird hingegen der Heimtrainer als liegefahrradähnlichs Trainingsgerät verwendet, befindet sich der Sitz des Zusatzgestells in Bodennähe, wodurch sich eine schräge oder annähernd vertikale Stellung der Füße auf den Pedalen der Drehmechanik ergibt. Um einen Kontakt der Füße oder der Beine des Benutzers des Heimtrainers mit dem Boden zu vermeiden, wenn er den Heimtrainer als liegefahrradähnliches Trainingsgerät benutzt, wird die Drehmechanik in einen größeren vertikalen Abstand vom Boden gebracht . Die Höhenverstellbarkeit der Drehmechanik des vorbekannten Heimtrainers ist dadurch realisiert, daß entweder die Drehmechanik selbst am Hauptgestell verschiebbar angeordnet ist oder daß das Hauptgestell höhenverstellbare Stützfüße aufweist, die es gestatten, das Hauptgestell samt der an ihm angeordneten Drehmechanik in der Höhe zu verstellen. Die Höhenverstellbarkeit der Drehmechanik durch verstellbare Anordnung der Drehmechanik am Hauptgestell oder durch die Verwendung von höhenverstellbaren Stützfüßen ist konstruktiv aufwendig, in der Bedienung unbequem und für die Stabilität des Heimtrainers nachteilig. Außerdem haben handelsübliche Heimtrainer, die nur als fahrradähnliches Trainingsgerät verwendet werden können, in aller Regel keine höhenverstellbare Drehmechanik. Handels- übliche Heimtrainer ohne höhenverstellbare Drehmechanik können daher mit einem Zusatzgestell für den liegefahrrad- ähnlichen Betrieb des Heimtrainers, wie er aus der DE-OS 26 52 892 bekannt ist, nicht nachgerüstet werden.Such an exercise bike, which can be used both as a stationary bicycle-like training device and as a stationary recumbent training device, is known from DE-OS 26 52 892. With this exercise bike, the additional frame for operation similar to a recumbent bike is either attached to a rear support leg of the main frame or connected to a frame part of the main frame holding the rear support leg. The height of the rotating mechanism is adjustable so that the most favorable ground clearance for the foot pedals of the rotating mechanism can be achieved when using the exercise bike as a bicycle-like or recumbent bicycle-like training device. If the exercise bike is used as a bicycle-like training device, it is advantageous if the rotating mechanism is close to the ground in order to make it easier for the user to get on and off the saddle of the exercise bike, with a rotating mechanism close to the ground because of the relatively upright sitting posture of the user and the resulting substantially horizontal position of the feet on the pedals of the rotating mechanism, a disturbing contact of the feet or legs of the user with the floor cannot occur. If, on the other hand, the exercise bike is used as a training device similar to a recumbent bicycle, the seat of the additional frame is located near the floor, which results in an inclined or approximately vertical position of the feet on the pedals of the rotary mechanism. In order to prevent the feet or legs of the user of the exercise bike from contacting the floor when using the exercise bike as a training bike-like exercise device, the rotating mechanism is moved to a greater vertical distance from the floor. The height adjustment of the rotating mechanism of the known exercise bike is realized in that either the rotating mechanism itself is slidably arranged on the main frame or in that the main frame has height-adjustable support feet that allow the height of the main frame including the rotating mechanism arranged on it. The height adjustability of the rotating mechanism through the adjustable arrangement of the rotating mechanism on the main frame or through the use of height-adjustable support feet is structurally complex, uncomfortable to use and disadvantageous for the stability of the exercise bike. In addition, commercially available exercise bikes that can only be used as a bicycle-like training device generally do not have a height-adjustable rotary mechanism. Commercial Conventional exercise bikes without a height-adjustable rotary mechanism cannot therefore be retrofitted with an additional frame for the exercise bike-like operation of the exercise bike, as is known from DE-OS 26 52 892.
Die Aufgabe der Erfindung besteht darin, den gattungsgemäßen Heimtrainer so weiterzubilden, daß die Höhenverstellung der Drehmechanik für die Umstellung des Heimtrainers vom fahrradähnlichen zum liegefahrradähnlichen Trainingsgerät und umgekehrt konstruktiv einfacher und bedienungsfreundlicher gestaltet ist und als Hauptgestell des Heimtrainers das Hauptgestell von handelsüblichen Heimtrainern verwendet werden kann, die nur als fahrradähnliches Trainingsgerät verwendet werden können.The object of the invention is to develop the generic exercise bike in such a way that the height adjustment of the rotary mechanism for converting the exercise bike from a bicycle-like exercise bike to a recumbent bike-like exercise device and vice versa is structurally simpler and more user-friendly, and the main frame of commercial exercise bikes can be used as the main frame of the exercise bike, which can only be used as a bicycle-like training device.
Die Aufgabe die Erfindung wird dadurch gelöst, daß bei Verwendung des Heimtrainers als stationäres liegefahrradähnliches Gerät das Verbindungsteil des Zusatzgestells an die Sattelhalterung des Hauptgestells angeschlossen ist, und das Hauptgestell gegenüber einer Normalstellung des Hauptgestells in eine Schräglage um den am Boden anliegenden Stütz- fuß des Hauptgestells gekippt ist, wobei die Drehmechanik einen größeren vertikalen Abstand vom Boden hat als in der Normalstellung des Hauptgestells, in der der Heimtrainer als stationäres fahrradähnliches Trainingsgerät verwendbar ist.The object of the invention is achieved in that when using the exercise bike as a stationary device similar to a recumbent bicycle, the connecting part of the additional frame is connected to the saddle holder of the main frame, and the main frame is inclined relative to a normal position of the main frame in an inclined position around the support foot of the main frame is tilted, the rotating mechanism being at a greater vertical distance from the floor than in the normal position of the main frame, in which the exercise bike can be used as a stationary, bicycle-like training device.
Das Verbindungsteil des Zusatzgestells kann entweder an den Sattelstützenhalter oder an die Sattelstütze angeschlossen werden, wobei der Anschluß des Verbindungsteils an die Sattelstütze den Vorteil hat, daß die Sattelstütze nicht entfernt werden muß.The connecting part of the additional frame can either be connected to the seat post holder or to the seat post, the connection of the connecting part to the seat post having the advantage that the seat post does not have to be removed.
Der erfindungsgemäße Heimtrainer hat den Vorteil, daß die Höhenverstellung der Drehmechanik allein durch eine Kipp- Schwenkbewegung des Hauptgestells um dessen Stützfuß erfolgt. Infolgedessen ist keine Einrichtung für die Höhenverstellung der Drehmechanik relativ zum Hauptgestell und auch keine Einrichtung zur Höhenverstellung des Stützfußes des Hauptgestells erforderlich. Es eröffnet sich dadurch die Möglichkeit, einen handelsüblichen Heimtrainer, der nur als fahrradähnliches Trainingsgerät verwendet werden kann, mit wenigen Handgriffen in ein liegefahrradähnliches Trainingsgerät zu verwandeln.The exercise bike according to the invention has the advantage that the height of the rotary mechanism is adjusted solely by a tilting-pivoting movement of the main frame around its support leg. As a result, there is no facility for height adjustment of the rotating mechanism relative to the main frame and also no device for height adjustment of the support leg of the main frame required. This opens up the possibility of converting a commercial exercise bike, which can only be used as a bicycle-like training device, into a training bike-like training device with just a few hand movements.
Vorzugsweise weist das Zusatzgestell einen im wesentlichen dreiecksförmigen Rahmen auf, an dessen einer Ecke sich der Stützfuß des Zusatzgestells befindet, und weist der Rahmen ein dem Stützfuß gegenüberliegendes langgestrecktes Rahmenteil auf, das bei Verwendung des Heimtrainers als stationäres liegefahrradähnliches Trainingsgerät sich im wesentlichen horizontal erstreckt und das Sitzteil des Sitzes mit Rückenlehne trägt. Die Dreiecksform des Rahmens des Zusatzgestells ergibt eine hohe Stabilität des Zusatzgestells. Die Dreiecksform des Rahmens des Zusatzgestells erlaubt auch eine einfache Herstellung des Zusatzgestells bei geringem Materialeinsatz .Preferably, the additional frame has a substantially triangular frame, at one corner of which the supporting foot of the additional frame is located, and the frame has an elongated frame part opposite the supporting foot, which extends substantially horizontally when the exercise bike is used as a stationary exercise bike-like exercise device and that Seat part of the seat with backrest carries. The triangular shape of the frame of the additional frame results in a high stability of the additional frame. The triangular shape of the frame of the additional frame also allows the additional frame to be easily manufactured with little use of material.
Vorzugsweise weist der Sitz mit Rückenlehne ein Sitzteil und ein Rückenlehnenteil auf, das in seiner Neigung relativ zum Sitzteil verstellbar ist. Zusätzlich kann das Rückenlehnenteil auch relativ zum Sitzteil höhenverstellbar sein. Schließlich kann der Sitz mit Rückenlehne in seinem Abstand vom Hauptgestell veränderbar sein. Durch diese Maßnahmen kann die Sitzposition des Benutzers des Heimtrainers als liegefahrradähnliches Trainingsgerät so eingestellt werden, daß er beste Trainingsergebnisse in bequemer Haltung erzielen kann.The seat with backrest preferably has a seat part and a backrest part, the inclination of which is adjustable relative to the seat part. In addition, the backrest part can also be height-adjustable relative to the seat part. Finally, the seat with backrest can be changed in its distance from the main frame. As a result of these measures, the seating position of the user of the exercise bike can be adjusted as a training device similar to a recumbent bike so that he can achieve the best training results in a comfortable posture.
Eine vorteilhafte Weiterentwicklung des erfindungsgemäßen Heimtrainers besteht darin, daß das Zusatzgestell einen weiteren Stützfuß aufweist und daß das Zusatzgestell zusammen mit dem Hauptgestell, mit dem es verbunden ist, um den einen Stützfuß des Zusatzgestells in eine aufrechte Lage kippbar ist, in der der eine Stützfuß und der weitere Stütz- fuß des Zusatzgestells sich auf dem Boden abstützen, das Hauptgestell vom Boden ganz abgehoben ist, und sich die Drehmechanik in einem vertikalen Abstand vom Boden befindet, der geeignet ist, daß der Benutzer des Heimtrainers die Drehmechanik zum Armtraining im Stand verwenden kann. Diese Weiterentwicklung hat den Vorteil, daß eine Umstellung des Heimtrainers von der Liegefahrradposition in die aufrechte Lage zum Armtraininig schnell und einfach bei einem sehr geringen zusätzlichen Bauaufwand erfolgen kann.An advantageous further development of the exercise bike according to the invention is that the additional frame has a further support foot and that the additional frame together with the main frame to which it is connected, can be tilted about the one support foot of the additional frame into an upright position in which the one support foot and the further support The foot of the additional frame is supported on the floor, the main frame is lifted off the floor, and the rotating mechanism is at a vertical distance from the floor, which is suitable for the user of the exercise bike to use the rotating mechanism for arm training while standing. This further development has the advantage that a change of the exercise bike from the lying bicycle position into the upright position to the arm training can be done quickly and easily with very little additional construction effort.
Auch der Heimtrainer gemäß der DE-OS 26 52 892 ermöglicht das Armtraining, allerdings in einer relativ unbequemen Bauchlage des Benutzers. Für das Armtraining in der Bauchlage des Benutzers ist bei dem vorbekannten Heimtrainer vorgesehen, daß das Zusatzgestell an die Sattelstütze des Hauptgestells angeschlossen wird, wobei das Hauptgestell in der Normalstellung verbleibt, in welcher der Heimtrainer als fahrradähnliches Trainingsgerät verwendet wird. Demgegenüber ermöglicht der erfindungsgemäße Heimtrainer, wenn das Zusatzgestell mit einem weiteren Stützfuß ausgerüstet ist, ein schonendes Armtraining, bei dem der Benutzer vor dem in einer aufrechten Lage sich befindlichen Haupt- und Zusatzgestell steht und die Drehmechanik mit den Armen betätigt.The exercise bike according to DE-OS 26 52 892 enables arm training, but in a relatively uncomfortable prone position of the user. For arm training in the prone position of the user is provided in the known exercise bike that the additional frame is connected to the seat post of the main frame, the main frame remains in the normal position in which the exercise bike is used as a bicycle-like training device. In contrast, the exercise bike according to the invention, if the additional frame is equipped with a further support leg, enables a gentle arm training, in which the user stands in front of the main and additional frame, which is in an upright position, and actuates the rotary mechanism with the arms.
Vorzugsweise weist das Zusatzgestell ein Gegengewicht auf, das an einer Stelle angeordnet ist, die sich bei Verwendung des Heimtrainers als liegefahrradähnliches Trainingsgerät oberhalb des einen Stützfußes befindet, so daß es sich beim Aufrichten des Heimtrainers in die aufrechte Lage in Richtung des Bodens absenkt . Das Gegengewicht kann an der Rückseite des Rückenlehnenteils des Sitzes des Zusatzgestells angeordnet sein. Eine andere Möglichkeit besteht darin, das Gegengewicht an dem weiteren Stützfuß anzuordnen.The additional frame preferably has a counterweight which is arranged at a point which, when the exercise bike is used as a training bike similar to a recumbent bike, is located above one support leg, so that when the exercise bike is erected it lowers into the upright position in the direction of the floor. The counterweight can be arranged on the back of the backrest part of the seat of the additional frame. Another possibility is to arrange the counterweight on the further support leg.

Der Rahmen 10 kann durch Herausziehen oder Hineinschieben des Verbindungsrohres 3 in seinem horizontalen Abstand von dem Hauptgestell 1 verändert werden, wodurch der Abstand zwischen dem Sitz 14 und den Pedalen 6 der Drehmechanik variiert und den Bedürfnissen des Benutzers für eine günstige Sitzposition relativ zu den Pedalen 6 der Drehmechanik 5 angepaßt werden kann .The frame 10 can be changed in its horizontal distance from the main frame 1 by pulling out or pushing in the connecting tube 3, whereby the distance between the seat 14 and the pedals 6 of the rotating mechanism varies and the needs of the user for a favorable seating position relative to the pedals 6 the rotating mechanism 5 can be adapted.
Das Anschlußrohr 23 des Verbindungsteils 3 ersetzt die rohrförmige Sattelstütze, an der sich ein Sattel befindet, auf dem der Benutzer sitzt, wenn er den Heimtrainer als fahrradahnlich.es Trainingsgerät verwendet.The connecting tube 23 of the connecting part 3 replaces the tubular seat post, on which there is a saddle on which the user sits when he uses the exercise bike as a bicycle device.
In den Figuren 2a bis 2c sind die verschiedenen Stellungen des in Figur 1 dargestellten Heimtrainers dargestellt. In Figur 2a steht, das Hauptgestell 1 mit der gesamten Fläche seines plattenförmigen Stützfußes 7 auf dem Boden. Dies ist die Normalstellung des Heimtrainers, in der der Benutzer den Heimtrainer als fahrradahnlich.es Trainingsgerät verwenden kann, bevor die Sattelstütze mit dem daran befestigten Sattel entfernt und an deren Stelle das Anschlußrohr 23 in dem Sattelstützenhalter 24 gesteckt worden ist.The various positions of the exercise bike shown in FIG. 1 are shown in FIGS. 2a to 2c. In Figure 2a, the main frame 1 stands on the floor with the entire surface of its plate-shaped support foot 7. This is the normal position of the exercise bike, in which the user uses the exercise bike as a bicycle device can be removed before the seat post with the saddle attached to it and in its place the connecting tube 23 has been inserted into the seat post holder 24.
Nachdem die Sattelstütze mit dem daran befestigten Sattel aus dem Sattelstützenhalter 24 entfernt und an deren Stelle das Anschlußrohr 23 in den Sattelstützenhalter 24 gesteckt worden ist, wie in Figur 2a ersichtlich, wird der Heimtrainer durch eine Kipp-Schwenkbewegung um die hintere Kante des Stützfußes 7 des Hauptgestells 1 in die in Figur 2b gezeigte Lage gebracht, in welcher der Stützfuß 11 des Zusatzgestells 2 auf dem Boden aufsitzt und der plattenförmige Stützfuß 7 schräg nach oben verläuft und sich das angestreckte Rahmenteil 13 zusammen mit dem Verbindungsrohr 21 im wesentlichen horizontal erstreckt . In der in Figur 2b dargestellten Lage des Heimtrainers hat die Drehmechanik einen größeren vertikalen Abstand vom Boden als in der in Figur 2a dargestellten Lage . In der in Figur 2b dargestellten Lage wird der Heimtrainer als ein liegefahrradähnliches Trainingsgerät verwendet . Durch den größeren Abstand der Drehmechanik 5 und damit der Pedale 6 vom Boden wird bei der in Figur 2b dargestellten Lage des Heimtrainers gewährleistet, daß der Benutzer des Heimtrainers beim Bewegen der Pedale 6 nicht den Boden mit den Fersen der Füße berührt .After the seat post with the saddle attached to it has been removed from the seat post holder 24 and in its place the connecting tube 23 has been inserted into the seat post holder 24, as can be seen in FIG. 2a, the exercise bike is tilted and pivoted around the rear edge of the support foot 7 of the The main frame 1 is brought into the position shown in FIG. 2b, in which the support leg 11 of the additional frame 2 is seated on the floor and the plate-shaped support leg 7 extends obliquely upwards and the stretched frame part 13 together with the connecting tube 21 extends essentially horizontally. In the position of the exercise bike shown in FIG. 2b, the rotary mechanism has a greater vertical distance from the floor than in the position shown in FIG. 2a. In the position shown in Figure 2b, the exercise bike is used as a recumbent exercise bike. The greater distance between the rotary mechanism 5 and thus the pedals 6 from the floor ensures that the position of the exercise bike shown in FIG. 2b ensures that the user of the exercise bike does not touch the floor with the heels of the feet when moving the pedals 6.
Bei der in Figur 2c dargestellten Lage des Heimtrainers stütz sich das Zusatzgestell 2 mit beiden Stützfüßen 11 und 12 auf dem Boden ab, während das Hauptgestell 1 vollständig vom Boden abgehoben ist . Das Umsetzen des Heimtrainers von der in Figur 2b dargestellten Lage in die in Figur 2c dargestellte Lage erfolgt dadurch, daß der Heimtrainer um den Stützfuß 11 nach hinten gekippt wird, wobei sich das Gegengewicht 20 nach unten absenkt und dadurch den Kraftaufwand für die Kipp-Schwenkbewegung des Heimtrainers um den Stützfuß 11 unterstützt. In der in Figur 2c dargestellten Lage steht der Benutzer vor dem Heimtrainer mit dem Gesicht dem Hauptgestell 1 zugekehrt. In dieser Position kann der Benut- zer die Pedale 6 der Drehmechanik 5 mit den Händen fassen und ein Armtraining durch Drehen der Pedale 6 ausführen. Das Gegengewicht 20 stabilisiert die in Figur 2c dargestellte aufrechte Lage des Heimtrainers .In the position of the exercise bike shown in FIG. 2c, the additional frame 2 is supported on the floor with both support feet 11 and 12, while the main frame 1 is completely lifted off the floor. The movement of the exercise bike from the position shown in FIG. 2b to the position shown in FIG. 2c takes place in that the exercise bike is tilted backwards about the support leg 11, the counterweight 20 dropping downward and thereby the effort required for the tilting pivoting movement supported by the exercise bike around the support leg 11. In the position shown in FIG. 2c, the user faces the main frame 1 in front of the exercise bike. In this position the user can zer grasp the pedals 6 of the rotating mechanism 5 with your hands and perform arm training by turning the pedals 6. The counterweight 20 stabilizes the upright position of the exercise bike shown in FIG. 2c.
Das in Figur 3 dargestellte zweite Ausführungsbeispiel weicht von dem in Figur 1 dargestellten ersten Ausführungs- beispiel in der Konstruktion des Zusatzgestells 2' ab. Das Hauptgestell 1 des in Figur 3 dargestellten zweiten Aus- führungsbeispiels ist das gleiche wie das Hauptgestell 1 des in Figur 1 dargestellten ersten Ausführungsbeispiels. Das Zusatzgestell 2' weist einen im wesentlichen dreiecksformigen Rahmen 10' auf, der ein langgestrecktes rohrförmiges im wesentlichen horizontal verlaufendes Rahmenteil 13' hat, in welchem ein Verbindungsrohr 21' des Verbindungsteils 3' verschiebbar gelagert ist. Auf dem rohrförmigen Rahmenteil 13' ist ein Verstellrohr 25 verschiebbar gelagert, an dem der Sitz 14' befestigt ist. Das Verstellrohr 25 ist durch nicht dargestellte Feststellschrauben in seiner axialen Lage relativ zu dem rohrförmigen Rahmenteil 13' arretierbar. Durch Verschieben des Verstellrohres 25 mit dem darauf angeordneten Sitz 14' kann der Abstand des Sitzes 14' von der Drehmechanik 5 variiert werden, um dadurch den Abstand der Körpergröße des Benutzers des Heimtrainers günstig anzupassen. Der Sitz 14' ist somit relativ zu dem Rahmen 10' in Horizontalrichtung verschiebbar.The second exemplary embodiment shown in FIG. 3 differs from the first exemplary embodiment shown in FIG. 1 in the construction of the additional frame 2 '. The main frame 1 of the second exemplary embodiment shown in FIG. 3 is the same as the main frame 1 of the first exemplary embodiment shown in FIG.
