Description

The invention relates to a single-track recumbent bike, in particular Low-flyer bike, with those in the preamble of the only patent characteristics mentioned.

The driver is known to be seated, half or fully lying between two wheels in a row. (e.g. book: The recumbent by Gunnar Fehlau, Moby Dick Verlag). It is also known for better adaptation to traffic there is a mechanism for height adjustment and distance provide adjustment of the seat. That way you can in city traffic for a better overview of traffic happen with the seat raised. For overland trips can then take the low sitting position because of the better aero dynamics can be selected. (e.g. DE 90 15 936 U1)

A single-track low-flyer bike is also part of the state of the art with rear-wheel drive, in which the drive of the rear wheel via two drive elements that move past the driver takes place, with a kind of pedal drive (forward and return stroke the pedals) in the direction of travel before the driver's center of gravity is positioned. This vehicle is steered with one ordinary bicycle handlebar. (GB 402908)

There is also a three-lane low-flyer bike with pedal crank drive in front of the driver's center of gravity and a side one Drive (e.g. chain) and indirect two-hand steering known. The driving force is here via an intermediate gear deflected a conventional rear wheel. (US 3913929)

The invention specified in claim 1 is Problem underlying low-flyer bikes with rear wheel driven complex chain guide (sometimes several deflection gear) to simplify.

This problem is addressed by an object with the Features listed claim 1 solved.

The advantages achieved by the invention are in particular that the chain (belt...) Without deflection, directly from the pedal crank drive, is passed laterally past the driver to the rear wheel. This has very decisive advantages:
The seating position can now be designed according to the driver's wishes without having to take the chain guide into account.

The lateral one-hand steering mentioned in the claim increases the design possibilities 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 limitation in the Construction are taken into account. This will be the good driver's position.

If you want to attach a full panel, you can because of the side chain guide an unrivaled achieve sufficient ratio of overall height: overall width (h: b).

The cross wind sensitivity is therefore essential less than the previous, single-track, fully clad Models.

The overall height of a closed body becomes alone determined by the geometry of the driver. Extremely deep built racing cars could be compared simply realize.

The seat can also be moved horizontally without any obstacle Move far forward or back. Since driver focus S, Drive Z1 and output Z2 almost in a horizontal Lying level, the angle Si-Z1-Z2 changes when adjusted only slightly from i = 1 to i = 2.  

People of very different sizes can do that use the same vehicle, without disadvantages in ergonomics and To have to accept biomechanics. One and the same Vehicle is therefore both for adults and for Suitable for children. A recumbent bike for the So offspring is a one-time purchase. The success when learning to ride a bike with the help of a Low-loader bike anyway much faster than when using it a conventional bicycle. The fear of a fall is much smaller here because the Fall height, and thus the risk of injury comparatively is low.

Due to the side chain guide, it is irrelevant whether the front wheel in front or behind the pedal crank drive is assembled. Even with a strong steering lock a collision between chain and front wheel due to the large lateral distance between both components in any case avoided. In the well-known, single-track low-flying bikes has so far not been able to solve this problem satisfactorily become.

The pedals are not mounted on the fly. The pedal axle is therefore not a cantilever undesirable torsional stresses in the frame largely avoided. To this day, this problem is also with muscle power-operated one-man one-track vehicles unsatisfied solved enough.

Lateral one-hand steering offers the following advantages in addition to those mentioned:
There is hardly any risk of injury in the event of a frontal impact. In this case, the known recumbent bikes steered at the top endanger the driver extremely.
Aerodynamically and ergonomically very advantageous, because the arm is comfortably stretched out, with elbow support, lying lengthways in the wind.
No additional roller bearings, such as with recumbent bikes steered below, are necessary.

The single track recumbent presented above offers due to the in claim 1 formulated features in muscle power-driven single-track vehicles so far unmatched Adaptability to the respective driver's wishes.

Notes on the drawings

The following simplifications have been made to emphasize the features set out in claim 1:
The frame was designed as a transparent, cubic box -
The driver as a stick figure -
The driver's joints are shown as points.

Claims (1)

  1. Single-track recumbent bike, especially low-flying bike, with pedal crank and rear wheel drive and in height, as well as a seat that can be adjusted at a distance from the pedal crank drive,
    characterized by
    that the drive via a single laterally passing driver element such. B. chain, belt, cardan shaft, etc., wherein
    the pedal crank drive has pedals which are rotatably provided on offset crank pins of the pedal crank shaft and which is positioned in the direction of travel in front of the driver's center of gravity, and
    the rear wheel represents a rotationally symmetrical body (e.g. double cone), the horizontal axis of rotation of which is longer than the driver, whereby
    the cross-sectional profile of the tread of the rear wheel corresponds to that of a commercially available bicycle tire and
    this vehicle is steered laterally with one hand, acting on the front wheel.
