Definitions

  • the invention relates to a full-body training device, which can be used both as a mobile means of transport ("walking bike”) and as a stationary exercise bike (crosstrainer / ellipses / whole-body trainer).
  • Stationary training devices also called exercise bikes - for the simultaneous strengthening of the muscles of almost the entire body, especially the arm and leg muscles are known.
  • many fitness equipment are used, which are referred to as full body / elliptical or crosstrainer and simulate the simultaneous use of arms and legs ergonomic running movement, which is similar to the movement of Nordic walking. Due to the motion sequence, however, only one flywheel is rotationally driven in such fitness devices, which often has a variable resistance due to an adjustable, functional brake device. As a result, the training intensity can be varied.
  • Fitness equipment of this type have, inter alia, stability reasons, a relatively high weight and are difficult to transport.
  • the training option on such stationary exercise equipment is usually limited to closed rooms, as lack of transportability, a change of the site, for example, outdoors, is hardly possible.
  • mobile exercise and locomotion devices which, however, do not have appropriate forced steering. Rather, the steering is usually via movable, preferably rotatable and / or swivel handles, which via a steering system, for example by Bowden cables, the Power steering.
  • a steering system for example by Bowden cables, the Power steering.
  • steering systems of this kind potentially involve, for example, the risk that the respective steering handle could be actuated in opposite directions with the different hands, which neutralizes a steering movement in this case.
  • these fitness devices are not designed for a stationary operation.
  • the object of the invention is to disclose a training or fitness device with improved and extended properties of the aforementioned specification, which gives the user the option of not only training the whole-body training device, for example on rollers as so-called cross trainer / elliptical trainer Hometrainer, but also as a bicycle-related means of transport, which also includes the upper body drive force moderate to use.
  • the fitness device should be safe and error-free steer.
  • the task is solved by a fitness device, which can be used mobile and stationary and has:
  • each a drive device each consisting of an arm drive rod, which is pivotally connected to a leg drive rod, wherein the leg drive rods transmit a torque u- about a sprocket and a chain on the rear wheel,
  • the training device has two drive devices, which consist of two articulated arm and leg drive rods that can be loaded and moved both by the hands and with the feet by an ergonomic movement.
  • the drive devices are arranged on a frame having elongated tubes, which in turn are connected to two front wheels and a rear wheel.
  • the two front wheels are connected by a front axle.
  • the leg drive bars have footprints for the user's foot.
  • the drive devices are arranged on both sides of a frame and connected to a crank mechanism, via which the generated torque is transmitted by means of chain or belt drive to a rear-mounted drive wheel.
  • the arm levers are used in simultaneous sammenspiel of weight shifts as a steering lever, which results in the principle-based advantage of a forced steering.
  • the distance between the two tread surfaces is chosen such that a particularly ergonomic movement is guaranteed.
  • the distance between the treads to each other is about 15 to 20 cm, preferably 17 cm, measured from inner edge to inner edge, the distance center to center is about 25 cm. If the distance is much greater, the user is too wide-legged, he is close, the legs are too close to each other. A hip-wide stand during use has been found to be optimal. For this reason, it has proven to be advantageous if the position of the treads is changeable in all directions, also a pivotability of the treads in a horizontal plane can be comfortable for the user.
  • the drive devices are arranged relatively close to the longitudinal central axis, their distance from each other is small. This causes only a small pendulum motion by avoiding strong off-center pulses. The greater the distance of the drive devices to each other, the more restless the fitness device behaves while driving or moving.
  • the training device can be folded such that it is reduced in both the height and in the length dimension. As a result, the fitness machine can be transported well and also save space.
  • the frame and the drive devices are made of the lightest and most durable material, they can be made of aluminum, steel or composite materials.
  • Part of a steering kinematics is a mounted at 90 ° angle to the frame front axle, which is connected via a joint suspension movable with the frame.
  • This joint suspension allows in mobile operation by appropriate weight shift a frame side tilt function, which is also part of the steering kinematics. Due to said weight shift and the resulting side tilt function of the frame, the at Cornering laterally occurring centrifugal forces compensated, which proves to be an additional advantage, in particular due to the relatively high center of gravity.
  • a preferred driving speed can be sensibly realized by means of a gearshift. From slow driving at walking pace - which could possibly also accommodate older exercisers - to sporty driving. It is particularly advantageous in this context that the foot pedals are not directly connected to the axis of the rear wheel, but that the torque generated is transmitted by means of chain or belt drive on a rear-mounted drive wheel.
  • a gearshift almost any design can be integrated arbitrarily.
  • the fitness device according to the invention is due to the standing use very easy on the back, the soft elliptical movements spares in contrast to running by little or no shock loads the joints of the user.
  • the steering is designed as a forced steering, street legal for the fitness machine is easily accessible. Furthermore, the claim of roadworthiness is borne by appropriate wheels sizes for sufficient ground clearance, by two independently operating brakes, as well as by a corresponding lighting device and a bell. For functional reasons, the overall width of the article according to the invention described here is comparable to the width of a standard bicycle handlebar or this dimension is not exceeded.
  • the return of the frame after steering maneuvers in the vertical starting position is meaningfully supported, the design-related lateral commuting while driving is - optionally speed-dependent - damped.

  • the side tilt function can be blocked for stationary operation by means of a mechanism for locking the frame side tilt function.
