Definitions
- Patent application No. 9410461 consisted, as has often been sought, of being able to increase the lever arm by lengthening the crank so that it is at the maximum at each positive phase of each crank revolution, without modifying or little, which approaches the diameter of the traditional circle developed by the classic cranks to which a cyclist is accustomed. Without changing anything to the more or less circular rail proposed in the previous patent application, mechanical variants can be proposed for the optimum variation in length of the crank which would avoid the telescopic proposal with 3 or more tubes.
- crank perpendicular to the crankset shaft is fixed by the sleeve, against
- This device will promote a displacement of the pedal relative to the motor shaft even larger than in patent 9510461 and more reliable than the telescopic solution with 3 elements. Any modification can be made there as soon as there is no alteration of the principle.
- FIGs 1 and 2 show this other solution to patent 9410461.
- the extendable crank is composed of a rod (9) (with its pedal (5) and its guide rollers (6) which roll on the rail).
- the rod slides in a sleeve (3) hollowed out over its entire length and integral with the motor shaft (l).
- the guide rollers mounted on differential (6), or any other design as in the previous patent represent a kind of index which controls the elongation and the withdrawal of the pedal thanks to the variation rail.
- the differential support and the axis of the pedal could possibly be the same, which supposes larger discs, (Fig.7 b).
- the integral sleeve (3) of the motor shaft thanks to the locking nut (2) has inside to promote the sliding of the rod (9) provided with the pedal, for example a packing (4) in " Nylon "(registered trademark) in the sleeve for a chrome rod in a square or rectangular tube (Fig. 2), or, a double pair of ball bearings (8) at each end of the sleeve (Fig. 3) if in this case the rod fitted with the pedal has an IPM shape so that the inside of the wings of the I is used for rolling ball bearings and if the sleeve is made up of two removable shells to facilitate assembly.
- a packing (4) in " Nylon "(registered trademark) in the sleeve for a chrome rod in a square or rectangular tube (Fig. 2) or, a double pair of ball bearings (8) at each end of the sleeve (Fig. 3) if in this case the rod fitted with the pedal has an IPM shape so that the inside of the wings of the I is used
- FIG. 4 Another means (Fig. 4) can also be envisaged, for example, still using the disc mounted on a support with circular rails or other similar shapes.
- the sleeve which constitutes the crank will have a very elongated oval shape (profile calculated according to the resistance of the material) with inside a large rectilinear slot, 2 small rails for the circulation of a carriage carrying the pedal and differential rollers, always guided by the rail mentioned above.
- Figure 4 indicates this form of crank (10) where the differential (6) and its rollers (17) runs on the rail (7) which differential is integral with the pedal (5) either in the same axis, or in an axis different, by means of the carriage (11) which circulates on the rails (12) of the crank (10). This allows the lever arm to be lengthened and retreated.
- crankset shaft can be as close as possible to the inside of the rail at around 4 cm, calculated by making the sum of: the half thickness of the crankset shaft + the thickness of the sleeve holder + the diameter of the inner roller of the rail, will allow us an increase from 4 to 36 cm, or 32 cm.
- the powers with the improvement proposed by the present patent application will bring increases in power beyond 1.90 times to reach, exceed for example if the motor shaft was moved back relative to the rail about 15 cm for example.
- We would get a 44 cm lever arm, an increase in force of 472/180 2.62 for 70 °.
- each turn of the crank will only cause a fraction of rotation of the motor shaft in the aforementioned case of 1/3 per crank, that is to say an increase of about 0.8%.
- Fig.8 shows a full-scale example of making the rollers totally dependent on the rail by a groove on the inside of the crown of the steering rail for one roller and another outside for the other. Catching up on defects in the various planes (disc-crank) is made only by the play in the bearings, which makes the disc crank perfectly secured both on the side of the rail (7) on its disc
- the differential (6) rotates on a support
