Abstract

In the previously known single-track low-wing bicycles with rear-wheel drive, the chain is guided in the middle, under or over the driver. This sometimes requires several reversing gearboxes. The driver is very restricted in his freedom of movement. The design effort is considerable and the ergonomic design options for driver positioning are very limited. With the innovations I propose, all of these problems can be solved. DOLLAR A With the new design, the chain is no longer guided in the middle, but to the side of the driver. This is realized by a rear wheel designed as a rotationally symmetrical body (e.g. double cone), the horizontal axis of rotation of which is longer than the driver is wide. DOLLAR A The new recumbent bike construction is just as suitable for everyday use as it is for sporty use. Last but not least, this design allows a very efficient design for full cladding.

Description

The driver is known to be seated, half or fully lying between two in a row. Wheels to positio kidneys. (e.g. book: The recumbent by Gunnar Fehlau, Moby Dick Verlag).

The invention specified in claim 1 is Problem underlying low-flyer bikes with rear wheel drive, complex chain guide (sometimes several Deflect gearbox).

This problem is solved by the in claims 1 and 2 listed features solved.

The advantages achieved by the invention are in particular that the chain (belt ...) without deflection, directly from the bottom bracket, past the driver to the rear wheel. This has very decisive advantages:

  • - The seating position can now be completely according to the wishes of the Driver can be designed without using the chain guide To have to be considerate.
  • - The lateral one-hand steering mentioned in claim 3 increases the design options even further.
  • - Since now both the drive and the steering elements completely banished from the driver's range of motion are now both physiological and biomechanical as well as ergonomic aspects without restriction in the Construction are taken into account. This will be the good driver's position.  
  • - For better adaptation to the traffic situation according to claim 4 also a mechanism for Höhenver position of the seat with this construction without problems realize. This way you could be in city traffic for a better overview of the traffic situation with drive up seat. Then for cross-country trips the low seating position because of the better aerodynamics to get voted.
  • - If you want to attach a full panel, you can due to the side chain guide a previously unseen achieve sufficient ratio of overall height: overall width (h: b). The cross wind sensitivity is therefore essential less than with the previous, single-track, fully ver dressed models.
  • - The height of a closed body is alone determined by the geometry of the driver. Extremely deep built racing cars could be compared simply realize.
  • - The seat can be according to claim 4 without hindrance nis horizontally as far forward or backward move. Because driver focus S, drive Z1 and Output Z2 are almost in a horizontal plane, the angle Si-Z1-Z2 changes during adjustment only slightly from i = 1 to i = 2. People from very under different sizes can therefore the same vehicle use without disadvantages in ergonomics and biomechanics to have to put up with. One and the same vehicle so that both adults and children alike moderately suitable. So there is a recumbent bike for the youngsters a one-time purchase. The success in learning of cycling should be possible with the help of a low-flying wheel anyway much faster than when using a konven bicycle. The fear of falling because it’s much smaller here because the fall height, and thus. the risk of injury is comparatively low.  
  • - Because of the side chain guide, it is irrelevant whether the front wheel is mounted in front of or behind the bottom bracket becomes. A collision occurs even with a strong steering lock between chain and front wheel due to the large side Distance between the two components avoided in any case. Both known to me, single-track low-flying bikes could do this The problem has not yet been solved satisfactorily.
  • - The pedals are according to claim. 5, not flying assembled. The pedal axis is therefore not a cantilever. This eliminates the undesirable torsional stresses in the Frame largely avoided. To date, this is also Problem with one-man, one-lane, powered by muscle power testify unsolved.
  • - The lateral one-hand steering offers the following advantages in addition to the ones mentioned:
    • 1. Little risk of injury in the event of a frontal impact. The recumbent bikes that I know above are extremely dangerous for the driver in this case
    • 2. Aerodynamically and ergonomically very advantageous, because the arm is comfortably stretched out, with elbow support, lying lengthways in the wind.
    • 3. No additional roller bearings, such as for example with long-wheel bikes steered below, necessary.
  • - Conclusion
    The single-track recumbent presented above offers, due to the innovations formulated in patent claims 1 to 5, an adaptability to the respective driver's wishes that was previously unattainable in muscle-powered single-track vehicles.
Notes on the drawings

The following simplifications have been made to emphasize claims 1 to 5 more clearly:

  • - The frame was designed as a cubic, transparent box,
  • - The driver as a stick figure,
  • - The driver's joints are shown as black dots.

If necessary, additional drawings can be added to each Claims will be delivered later.

Claims (5)

1. Single-track (low) recumbent wheel with rear-wheel drive, characterized in that the drive of the rear wheel is carried out via a drive element (chain, belt, cardan shaft ...) which leads past the driver. The bottom bracket is positioned in the direction of travel in front of the driver's center of gravity.
2. Single-track (deep) recumbent with rear-wheel drive Claim 1 characterized in that the rear wheel has a rotationally symmetrical body (e.g. double cone), whose horizontal rotation axis longer than the driver is wide. A trade Usual bicycle tires can possibly at the maximum through knives can be mounted.
3. Single-track (low) recumbent bike according to claim 1 and 2, characterized, that this vehicle is steered sideways with one hand.
4. single-track (low) recumbent bike according to claim 1 and 2, characterized, that a combinable seat adjustment in height and at a distance from the bottom bracket shaft.
5. single-track (low) recumbent bike according to claim 1 and 2, characterized, that the pedal axles are not cantilevers.
