Abstract

A human powered water craft includes pedals 5, drive chain 7 and rotatable paddle wheels. The vehicle may be steered using a mechanism within a waterproof housing. The vehicle has a flat bottom for shallow waters and has a seat for the driver.

Description

Pedal Powered Water Craft Description
The Pedal Powered Water Craft is a boat which has as motive force pedal power and can be driven like a vehicle on rivers, reservoirs, pools Tic and could be used as water borne bumper car.
The Pedal Powered Water Craft is shaped to cut through the water with efficiency and due to its wide width in proportion to its length the displacement of the craft in the water in terms of the height the base of the craft is below the water level is low therefore the craft may be used in shallow water such as Low depth rivers and the driver of the vehicle car be assured of a dry ride skimming along the surface cf the water. The rudder need not be longer than fifteen centimetres. Fig 1 shows the Pedal Powered Water Craft being driven by a driver.
The steering cog housing 2 in Fig 3 and also shown in Fig 2 has enclosed cogs for waterproofing and to stop dirt and other contaminants getting into the cog mechanism which if they were to get into the Cog mechanism may hamper its efficient operation. The inside of the steering cog housing is shaped such that it accepts and retains in their correct positions the internal dynamic rotateable parts in their correct alignment. The cog arrangement at the steering wheel column end is such that the steering column is slightly at an angle up from the horizontal and has at its other end a steering wheel 3 in Fig 3 of plastic moulding.
The cog arrangement converts near horizontal rotation about a line of axis movement of the steering wheel to vertical movement at the secondary cog 4 in Fig 2 whose teeth engage with the cog that is attached to the steering column 3 in Fig 2. These cogs are both conically shaped. The secondary cog is attached to a plastic rudder 4 in Fig 3 via a bolt fixture of rudder to cog which turns the craft left or right when the steering wheel is rotated left or right so steering of the steering wheel is relative and corresponds to turning affect of craft due to appropriate rudder rotation. To keep the cogs in position inside the steering cog housing attachment of cogs could be but not necessarily by way of enclosed bearing races, just the shaping of the cog housing could be used alternatively. Cog 3 in Fig 2 is kept in position by discs 2 in Fig 2. Cog 4 in Fig 2 is kept in position by discs 5 in Fig 2. Thus steering wheel-column din Fig 2 is attached to rudder column 6 in Fig 2. The rudder could be attached to the vertically rotating steering cog by way of a sheaf which may simply be screwed to the vertically rotating steering cog or be bolted into place via hole running through the sheaf centre diameter of the sheaf and through the diameter of the vertically rotating steering cog which then are connected aligned and fixed together by a bolt running through both nets of holes.
The drive of the craft is by a chainwheel in Fig 3 having a bearing race at its centre and which has attached to it at its centre pedal arms which have pedal in Fig 3 at their ends and on these pedals foot stirrups so that the feet of the driver do not fall off the pedals. Rotation of the chainwheel in Fig 3 rotates a chain 7 in Fig which is covered and housed for safety by a chain housing 8 in Fig 3. The chain is attached to a chainwheel g in Fig 3 which has a bearing race at its centre 10 in Fig 3 and the chainwheel has a cog around its outer surface, this cog connects to another cog 11 in Fig 3 which has an axle 12 in Fig 3 connecting this cogs movement to soft compressible rubber rollers 19 in Fig 3 and 13 in Fig 3 and hence to the ends of the water wheel which are 21 in Fig 3 and 16 in Fig 3, The ends of the water wheel roller have bearing races at their centre, one is shown as 17 in Fig 3, both of these bearing races are to either side left right of the seat.
The soft compressible rubber rollers have bearing races at their centre one is shown as 14 in Fig 3. The soft compressible rubber roller making pressure contact with a water wheel end is shown at lo in Fig 3. The soft compressible rubber rollers have a cover 15 in Fig 3.
The water wheel roller is connected to the ends of it by means of an axle. Both the ends of the water wheel and the forward rollers are kept out of the water by housings which in the case of the water wheel roller goes below the water line as a semi hollow disc. There is barrier of plastic with a hole in each side one side is shown as 22 in Fig 3 between the ends of the water wheel roller (which comes in three sections the thin disc ends 21 in Fig 3 and 16 in Fig 3 and the central wide turbine, 23 in Fig 3) and the main body of this roller for waterproofing. This hole is for the axle of the water wheel to pass through. This water wheel roller has got slats in it which engage with the water below the water line and below the base of the craft thus providing the force which moves the craft. The water wheel roller is surrounded by plastic above the base of the craft.
There is a barrier of plastic between the soft compressible rubber rollers and the cog 11 in Fig 3 which is shown as 20 in Fig 3 through which the axle 12 in Fig 3 passes. Both the forward rollers and the water wheel roller are enclosed by the seat 1 in Fig 3 as a safety feature so that fingers etc cannot be crushed by getting caught up in the mechanism. This construction also ensures the mechanism is entirely waterproofed even if the craft capsizes.
The craft has upraised edges for buoyancy and to keep the craft and the occupant shielded from the water.
All the metal parts including the chainwheels front and rear, pedal arms, pedals, pedal foot stirrups, chain, steering cogs, steering bearing races, tubular steel column, forward roller cog, axles, roller bearing races and bolts and nuts are of stainless steel to prevent rusting. The rest of the craft is of waterproof and light tough durable plastic capable of taking stresses and strains, possibly ABS plastic injection moulded except for the rubber pressure connectors rings of the forward roller.
The driver of the craft sits comfortably on the seat with his or her feet forwards turning the pedals and with arms outstretched and hands clasping the steering wheel to turn the craft wherever he or she wishes.
The seat and chain guard are removable by release of bolts so that the chain and bearing races and cogs and rubber pressure connector rings may be lubricated with oil or grease put on them and the steering cog housing may be opened up again by bolts being loosened and removed to lubricate or grease bearing races and cogs for maintenance or replacement.
The steering column cog housing is split into two halves length wise vertically and to get inside it it is removed from the craft by loosening stainless steel bolts from above the craft which go into each of the split sections vertically at the sides of the split sections and then dividing the sections by loosening bolts horizontally placed which join the sections.
Bolts attach the chain guard and the seat to the craft from above Bolts attach the bearing races and all bolting placements and fix them at the appropriate positions which go into encapsulated in plastic stainless steel nuts which use injection moulding placement techniques (for this to be done correct positional placement of nuts could be by bolts and then injection moulded around these positions and then removal of these temporary bolts, shape of nuts is what keeps the nuts in position and stress/strain of the plastic which surrounds them minimal so that the plastic does not become deformed, weakened, worn away and does riot experience stress/strain deformation and there is always an accepting nut to receive the bolt which can be counted on producing a fix between parts for as long as is desired.
