Description

Cargo bike/roller - training bike/roiler State of the art:

The bicycles commonly used today, Fig. 1, essentially consist of the frame (R), the wheels (LH and LV) and the chain drive (K). The size of the parts is determined on the one hand by the size of the rider and on the other hand by the speed to be achieved, as the pedaling speed suitable for the person must be matched to the possible wheel diameter via the gear ratio. The disadvantage is that both the frame and the wheels are relatively large. This has further disadvantages, such as high weight, bulky construction, unsuitable for loads, folding bikes can only be implemented with major technical compromises, inflated tires must be used, etc. This is why cargo bikes, shopping bikes and supply bikes are hard to find. The bikes almost only train the leg muscles.

These aspects also largely apply to scooters, which are also mostly geared towards the needs of children and are therefore relatively slow and unsuitable for longer distances.

Description:

The registered vehicles (bicycle, scooter), Figures 2 to 7, do not have a conventional frame, but a type of low-lying base plate (B). This can also be a profile, a bridge or rods, etc. In addition, the wheels (LH and LV) are much smaller. In order to still reach speeds that we consider appropriate and are used to from standard bicycles, a high gear ratio from the pedal (P) to the rear wheel (LH) is necessary. The high gear ratio (Ü) can be achieved by gears, multi-stage chain wheels or a combination of these, etc.

The base plate can be extended to form a luggage rack (G) at the rear. The area for carrying loads is therefore very low. The area, length (LG) and width (BR), can be designed for much larger loads than for bicycles.

Vehicles constructed in this way can transport much larger loads, as they no longer have to be lifted as high and are easier to control due to the more favourable lever ratios - load height (KAH) / handlebar height (LA). The lever ratios can be seen in Fig. 1 and Fig. 2.

recognize.

The distance between the base plate and the running surface and the diameter of the wheels (R) are determined by the fact that the necessary ground clearance must be maintained in curves on two-wheeled variants, as is the case with conventional bicycles. On the other hand, it is often desirable to have as low an entry (E) as possible. This is achieved by placing the bearings (A) for the pedals and transmission gears (chain) wheels on the base plate (B) upwards (Fig. 5).

The small diameter of the wheels also allows the use of "solid rubber wheels".

There is practically no offer on the market for very small wheels (12 inches and smaller), especially for spoked wheels with hub gears. For the wheels (LH) and (LV) it is therefore advantageous to use disc wheels or at least partially solid wheels.

Individual aspects of the measures described have already appeared in the literature and on the market. However, they have not been able to prevail because, viewed in isolation, they offer too few advantages.

An essential aspect of this application is the combination of technical measures such as low floor plate/small wheels/high gear ratio or low floor plate/small wheels/high gear ratio/large, low loading area, etc.

The vehicle can be equipped with just two wheels, as is the case with a standard bicycle. Fig. 2 shows a vehicle with three wheels. One of the advantages of this is that it can be parked free-standing.

Fig. 3 shows a scooter based on the base plate principle described. The footboard (Tl) is moved downwards by the rider's weight shift. This causes the wheel (RA) to rotate, which is transferred to the rear wheel (LH) via the gear ratio (Ü). This process causes the footboard (T2) to be at the top. If the rider shifts his weight so that the footboard (T2) is pushed downwards, the rotation of the wheels (RA) and (LH) continues as described above. The scooter moves forwards.

The leg force applied to the footboard (Tl) can be supported by the rider pulling the lever (Hl) towards him with his hand. This force is also transferred to the rotational movement of the wheel (RA) etc. via the lever (Hl), joint (Gl) and the device (Tl). The movement can also be forced exclusively in this way so that only the arm muscles are trained.

The same applies to the steering on the side of (T2). The levers can also be arranged so that the rotary movement in (LH) is supported by pressing lever (Hl) etc. The dimensions in Fig. 3 are only to be understood as a rough guide. Steering is achieved by a lateral movement of the levers (Hl) and (H2).

Such a system can also be constructed by using a gear with a freewheel or with two freewheels. In this case, pressure is first exerted via the freewheel gear on the side of (Tl) - Fig. 3). During this time, (T2) is moved upwards, e.g. by spring force. The impeller is then driven by force on (T2), and the freewheel enables the return movement of (Tl).

Both examples are based on the intention to use both leg and arm muscles for locomotion (together or exclusively).

Fig. 4 shows an example of a bicycle with pedals and two rear wheels. In this case, an additional gear, e.g. two gears (Z), is necessary to reverse the pedal movement in the second phase. A corresponding vehicle can also be equipped with only one rear wheel.

Another advantage of the described designs is the possibility of easily building collapsible, push-together, foldable, etc. vehicles that are also very stable. In Fig. 5, the vehicle is disassembled into two parts. The base plate, rail (SV), etc. of the front part can be inserted into the rear part (SH). Both parts can be fixed using screws (S), etc. This is possible both in the extended driving position and in the pushed-together transport position (Fig. 6A). A second option for transporting the vehicle is shown in Fig. 6B.

The design of the vehicles also allows for partial cladding without having to make a great deal of effort.
