Definitions

  • the invention relates to a drive unit for driving a wheel of a training device by means of a user's pedal force and a training device with such a drive unit, according to the respective independent claim.
  • Training equipment for physical exercise is well known and available in countless variations depending on the part of the body being trained.
  • One category of training equipment is aimed at training the leg muscles, for example.
  • training devices that also train stamina, for example.
  • Such training devices can be further subdivided, with some of them being similar to bicycles and, as stationary devices, only having a rear wheel that is driven in place using leg muscle power, and as mobile devices using two wheels.
  • a subtype of the latter devices are so-called elliptical trainers, which are designed as mobile devices. These usually have a rear wheel, a front wheel, a frame, a steering unit and a drive unit. They differ from conventional, bicycle-like training devices primarily in the modified path described by the pedals during a full rotation. While the pedals on conventional bicycle-like devices describe a circular path, elliptical trainers are characterized by a modified path, which is mainly due to a modified drive unit.
  • the drive unit of a WO2008063499 The well-known elliptical trainer with elliptical track comprises two elongated pedal platforms as drive arms, which are connected to a crank unit at the back and attached to guide rails provided in the frame of the elliptical trainer at the front by means of rollers. Due to the circular movement of the crank unit at the back and a linear movement of the rollers at the front in the guide rails, an elliptical path of the pedals is created during use. During use, the person stands on these pedal platforms and transfers the leg power to the crank unit, which transfers this power to the rear wheel for propulsion.
  • the object of the present invention is to provide a training device that is compact, versatile and gentle on the joints.
  • the frame segment has at least one guide rail on the left and right sides, in which the at least one guide roller of the left or right drive arm of the drive unit can be accommodated in a linearly displaceable manner parallel to a longitudinal axis of the down tube.
  • the coupling of the drive unit is rotatably attached to the frame between the frame segment and the rear wheel.
  • the training device also includes a power transmission element, by means of which a user's pedal force can be transferred to the rear wheel and causes it to rotate.
  • the power transmission element is preferably a chain or a belt.
  • the drive arms Due to the L-shaped or V-shaped design of the drive arms in combination with the pedals that are not integrated into the drive arms but are arranged to the side of them, it is possible to provide a drive unit that allows a compact design of the training device and thus enables improved use in stationary situations as well as on the road and off-road. Due to the shorter wheelbase, the training device is easy to transport and can be manufactured not only in a version where the user has to stand, as in the case of an elliptical trainer with pedals integrated into the arm, but also in a seated version.
  • the left and right roller systems of the drive unit according to the invention each comprise a lowering arm.
  • the lowering arm is rotatably attached to the at least one roller at an upper end and rigidly attached to the respective drive arm at the lower end in the area of a front extremity, so that the front extremity of the respective drive arm is always lowered in relation to the at least one roller.
  • This advantageously extends the horizontal elliptical path of the pedal without having to change the length of the cranks.
  • the elliptical path extended in this way results in a smoother pedaling movement of the user in general and thus helps to protect the joints.
  • each lowering arm and the respective drive arm is adjustable in such a way that a distance between the front extremity of the drive arm and the at least one roller can be changed by the user.
  • This longer horizontal stroke of the elliptical path enables a more optimal flow of force from the user on the device. This also allows the user to adjust the height of the Adjust the pedals from the ground depending on your body size and preferences.
  • the attachment between each crank and the respective drive arm is adjustable such that a distance between the rear extremity of the drive arm and the respective crank point can be changed by the user.
  • an extension of the drive arm (greater distance between the rear extremity of the drive arm and the coupling point) also contributes to the longer horizontal elliptical path for the pedals.
  • Shortening the drive arm results in an advantage in a mobile training device, namely the possibility of using a front wheel with off-road equipment such as off-road tires and a corresponding suspension fork, since the shortening creates more distance between the drive arm and the front wheel.
  • the clutch is designed as a gear for a chain drive or as a pulley for a belt drive and can be mounted on a frame of the training device.
  • the drive unit according to the invention can thus be easily adapted to existing frames and rear wheels. It is preferred if the clutch can be mounted in front of the wheel of the training device to be driven.
  • the left and right drive arms each comprise a clutch-side leg, to which the respective left or right crank is rotatably attached, and a roller-side leg, to which the respective left or right roller system is rotatably attached.
  • the clutch-side leg is longer than the roller-side leg. This contributes to the compactness of the training device. by making the guide rail shorter, thereby reducing the overall length of the training device.
  • the coupling-side leg and the roller-side leg can be rigidly connected to one another or made in one piece.
  • the legs are angled to one another according to the respective shape.
  • This design has the advantage that the two legs can be manufactured independently of one another and the drive arm can then be adapted to different frames for different training devices and user needs by varying the connection angle.
  • the coupling-side leg and the roller-side leg can be bent into one another and made in one piece.
  • This has the advantage that the drive arm is more rigid and therefore more stable. It also reduces the assembly effort and the number of connections, such as welding points.
  • the left and right drive arms each have a reinforcing leg, which additionally rigidly connects the clutch-side leg to the roller-side leg.
  • the reinforcing leg thus forms a triangle with the clutch-side leg and the roller-side leg and increases the stability of the drive arm. It can be straight or curved. It can be attached to the respective free extremity of the clutch-side leg and the roller-side leg, or it can be attached at any point along one or the other or both legs. It can also be manufactured in one piece with the two legs.
  • the pedals are preferably each pivotally attached to the clutch-side leg of the associated drive arm.
  • This has the advantage that their position closer to the rear wheel also allows the use of a seat for the training device, since the pressure surface for the pedals is essentially under the body's center of gravity, which is particularly advantageous for a mobile training device, as the seat also offers the opportunity to rest on longer journeys.
  • This is not possible, for example, with the elliptical trainer mentioned at the beginning with pedals integrated in the drive arm, due to the pedal surfaces being positioned towards the front wheel, and accordingly this device does not have a seat.
  • the fact that the pedals on the drive arm can be rotated also results in better ergonomics when pedaling.
  • the design is more compact, as the pedals are mounted relatively close to the coupling point.
  • the roller systems each have at least one guide roller and at least one counter roller, which are offset from one another in such a way that each roller can be accommodated in a linearly displaceable manner back and forth in its own guide rail of the frame of the training device.
  • the guide roller on the drive arm takes the main weight of the user and slides back and forth on the guide rail.
  • the counter roller absorbs the counter forces and serves to stabilize the drive arm and prevents the drive arm from slipping off the guide rail. It is preferred if the guide roller and the counter roller of a roller system have different diameters, with the diameter of the guide roller being particularly preferably larger than the diameter of the counter roller, since the guide roller bears the main weight. This saves material and the guide rail can be made smaller.
  • Positional terms such as left and right or up and down refer to the usual meaning in connection with a bicycle.
  • path refers to a path actually described by the pedal, e.g. the contour of an ellipse.
  • path refers to the horizontal or vertical projection of the path or, in general, to a linear path.
  • a clutch is defined only as a drive-side part, e.g. as a rack/chainring of the drive unit, in order to distinguish between the drive unit assembly and the rest of the training device, which includes the counterpart (pinion/hub) arranged on the rear wheel.
  • Fig.1 shows a schematic representation of the typical path that a human foot describes when walking.
  • x indicates the walking direction and y the lifting height of the foot in relation to the heel.
  • the leg position of the right leg of person P is shown schematically and is intended to illustrate the position, in particular in relation to a ground center line b between the feet.
  • the movement or the path begins with a so-called initial swing IS, in which the leg is raised for the step.
  • a so-called middle swing MS in which the leg is moved forwards until the so-called final swing TS.
  • a so-called heel strike HS follows, after which the foot is on the ground for the period of the movements already described with the other foot.
  • Fig.2 shows schematically the typical path that a human foot describes when riding a bicycle. This path is a simple circular path that is determined by the bicycle's gear wheel, also called the chainring.
  • Fig.3 shows an elliptical path that a human foot describes when using the training device according to the invention.
  • the training device is also referred to below as an elliptical trainer. It is characterized in that a pedal describes an elliptical path during a complete pedal rotation, in which in the case of the present invention (see Fig.5 ) a front vertex of the ellipse is higher than a rear vertex of the ellipse (black dots in the figure).
  • the dimensions of the elements of the drive arm and the guide rail are chosen such that the main axis of the ellipse, which connects the two vertices shown, is longer than twice the length of the cranks and/or longer than a clutch-side leg of the drive arm.
  • the main axis of the ellipse corresponds to a linear path that the drive arm travels on the guide rail during a complete pedal rotation. This enables an ergonomic elliptical movement sequence despite the smallest space.
