Abstract

The two crank arms include telescopically slidable sections 2 and 3 that may be locked together in an elongated or shortened position. One of the crank arms is connected to an epicyclic gearbox pinion 12 which, in use, rotates three gears 6 via three coaxial pinions 8. The three gears 6 subsequently rotate a chain ring 4 to power for example a bicycle. Three pawls 9 prevent counter-rotation of the three gears 6.

Description

I

Title: THE HUMAN-POWERED ENGINE, (HPE).

BACKGROUND

My English is low, but I tray to study it. Our first English teacher lovely lady Georgia Smith is bicyclist, have preferred to ride at the bicycle, than all road vehicles. She dreams to have some bicycle compete able to existing road vehicles and to easily ride UP HILL. I & my darling wife Eleanor, we love our teacher, therefore I promised to create, especially for her, some powerfi.il modern bicycle.

For healing and training my heard, every day I walk along the Chingford Mount Road, and I hope to obtain the resource for manufacture this modern, excellence bicycle, because I am too have dream to easily ride UP HILL e. g.. over the Chingford Mount. The bicycle is payload to everybody. A famous French long-liver was to be bicyclist until aged 122.

By the way to execution my promise, I met different technical problems, including the torsion of crank-arm. In 1966 Italian monks restoring the manuscripts of great dreamer Leonardo da Vincy discovered a sketch from about 1490 of a machine remarkably similar to a modern bicycle, complete with pedals and chain drive. Still, his idea for bicycle almost certainly never left the drawing board, but nobody cold create the pedal have power enough to easily ride UP HILL.

In all the world the mankind are looking for the way to develop the bicycle, as best beloved invention.

For better explanation my invention, I referee e.g. to (Ultimate bicycle book. Author, Richard Ballantine and Richard Grant.

From written and completed by the world's best-selling bicycle authors, Richard Ballantine and Richard Crant, Richard' s Ultimate Bicycle Book' is definitely clear, there is begin the time and there is all premises to create the powerfiul bicycle have compete against all road vehicle.

The ultimate means of energy efficient (IHPV) International Human Powered Vehicle, comprising hundreds modifications, are achieving the speed 30 mph; 37 mph; and top speed 50 mph at the Track Ring. But at last time the developing process of human powered devices will be drop itself, because the pedal lever, called Crank-arm 175 mm, is too short, therefore have very low power.

For modern surprisingly achievement of bicycles inventions I may offering my permissive the method to increase the powerful of human-musklle engines until 225% AIHD more.

DESCRiPTION

The description conents three modifications of "The most powerful pedal engine".

1 - modificaion ealld "LE". (Figure 2 Eigure 3; Figure 4; Figure 5; Figure 6; Figure 22).

2 - modification called "SELINA". (Figure 7; Figure 8; Figure 9; Figure 10; Figure 11; 22).

3 - modifiation called "OLGA". (Figure 12; Figure 23).

This invention relates to device, means for increasing the efficiency of human-muscle power.

While the riders are rotating the pedal, they sometime needs to increase the power it e.g. bicyclist to ride UP HILL, or pilot of pedal-powered aircraft to start and climb in heaven.

However, the pedal's lever, called Crank-arm 2 (Figure 21) have possessed ultimate size 175 mm, couldn't be elongate by vertical clearance in cause of human body construction, it may have variable elongation at horizontal level direction (Figure 22; Figure 23) to back or force ahead. The have elongate pedal lever, called Crank-arm 2&3, increases it power rateably to elongation. This power will transforms, through the Gear box 41, to rotation movement. Ref. (Ultimate Bicycle Book, page 27, Gear and gear ratios; page 18, The human engine; page 162, Adjustment for comfort) All three modifications works at two mine state: first state & second state.

first state - the lever called Crank-arm 2&3 is at consuetudinary, non elongation, position (size 175 mm) suitable for driving.

second state - the lever called Crank-arm 2&3 is at elongate position, powerful pedal.

At first state (Figure 21) pedal rotates as old ordinary pedals. It suitable for use at the low power e.g. by riding at horizontal way or hill down. The rotating pedal at first state may wear down, disadvantage the human body.

At second state (Figure 22; Figure 23) the powerful pedal suitable to slow rotating by high speed, emergency brake, easily riding UP HILL at mountain bike and by riding a long way e.g. tourism. Ref. (Ultimate Bicycle Book, page 44, Riding technique).
