Abstract

The bicycle has conventional foot pedals for driving the rear wheel and a second crank drive system with hand pedals for powering the front wheel. The bicycle has a U shaped handlebar so that when the hand pedals are being rotated the cyclist's forearms can be used to steer the bicycle. The rotation of the hand pedals is transmitted to the front wheel by means of a conventional bicycle drive train and gears.

Description

INVENTION Hand and or foot powered Bicycle SPECIFICATION This invention relates to a Bicycle Bicycles are well known vehides which comprise of a lattice body made of tube steel,with two spoked wheels aSatched.They atso have a seat a handlebar and brakes.The power to drive the cycle forward is derived from the legs of the cyclist via a set of pedals rotating around a toothed crank wheel driving a chain.This chain driving the back wheel of the cycle by means of a geared toothed rear wheel and gears.
Biycles are an efficient means of transport and an efficient means of exercising the heart and lungs and the lower half of the cyclists body muscles e.g. legs lower back stomach.
However cycles are not totally effective in utilising the full capacity of the cyclists body and do not exercise to any great extent the upper half of the body e.g. arms,chest, shoulders.
THE INVENTION (For the purposes of explanation of this idea the term pedaling refers to operations caned out by hand or foot All spelling is U.S. version.) A Bicycle capable of being powered by both hand or feet or hands and feet simultaneously whilst still being capable of being steered safely by the cyclist The said cycle comprises of a frame,fnont and rear wheels rotably mounted on the frame,front and rear wheels being driven by chains connected to two separate cranks.
The assembly is that of a conventional bicycle with the addition of a second drive system situated forward of and above the front wheel of the bicycle.This second crank is cored to the front wheel forks by means of two forks attached to the crank case and intersecting halhvay up the two front wheel forks.This second drive system is connected to the front wheel by a conventional cycle drive chain and gears.The front wheel is like that of a conventional rear bicycle wheel in as much that it has a gear cog assembly at its centre.
In order that the bicycle can be steered whilst being hand pedaled the design of the handlebars is such that the cyclist uses their forearms and elbows rather than their hands which obviously when hand pedaling are in contact with the front pedals.The design of the handlebar is such that it can also be held in a conventional manner i.e. with the hands gripping the handlebar if pedling only with the feet or freewheeling or maneuvering at low speeds. w handlebar is shown in detail in Diagram 4 The handlebar is a U - shaped piece of tubing attached to the top of the steering column The arms of this handlebar protrude along side of the hand pedals rotary pathway and above the front drive crank which is itself attached to the front of the centre upright section of the the sreering column see dig 4.The forward handlebar arms are spaced wide enough apart to allow the cyclists arms to pass through so as to allow the cyclists hands to be in contact with the front drive crank pedals but close enough together to allow if necessary the cyclist to squeeze their forearms against said bars to lever the steering column to left and rightfliese protruding front arms are angled at 45 degrees to the horizontal plane and at 90 degrees to the crossbar.

Claims (7)

  1. CLAIMS 1. A Bicycle that can be powered by both hands and feet whilst simultaneously being steered.
    The said device being a upright bicycle simultaneously comprising a front mounted drive system operated by the hands with handlebars to provide steering by means of the cyclists forearms whilst the hands are operating the drive mechanism.
  2. 2. A bicycle as claimed in (1) which has a second drive systern mounted forward of the handlebar headstock of the bicycle.
  3. 3. A bicycle as claimed in (1) which has U shaped handlebars with extended upward arms to provide steering by means of the cyclists forearms whilst the hands are on handles on the front drive system
  4. 4. A drive system claimed in (2) which includes a back pedal brake or brake levers on the pedal axles.
  5. 5. A drive system claimed in (2) which utilises a chain, belt or tooth grip belt as the driving mechanism.
  6. 6. A drive system as claimed in (2) supported from the framework of the bicycle by structural members which retain the front drive system axle bearings in a fixed position relative to the front wheel forks and front wheel.
  7. 7. A structural support system as claimed in (6) which does not necessarily require structural modification to the elements of an existing bicycle.
