The fourth part comprises: (A) rotatable front wheel frame 333, supporting a front carrying wheel, riding driver, pedal, chain and sprocket assembly, and supported by the front panel assembly 303, 304, 308.

The rotatable front wheel frame is provided with a vertical shaft 324 rotating through the hinging joint 308.

(B) a guiding front conventional ground engaging wheel 335,

(C) a chain and sprocket assembly with . foot pedals 336, operated by the riding driver, (D) a riding driver's seat.

337, (E) a removable upper hinge 338 fastened to front wheel frame 333, used to allow the assembling and the dismantling of the fourth part assembly, (F) a right hand steering handle 339 with brakes and speed control, (G) a left hand steering handle 340 with brakes and speed control.

The so described three wheel vehicle is operated by one to five riders; two riders occupying the two seats on the right wheel , two riders occupying the two seats on the left wheel in addition to the driver riding on the front wheel, the front right rider and the front left rider operate each; foot pedals and hand cranks at the same time.

The front driving rider commands the control devices of the vehicle, namely: the speed, the brakes, the forward backward

- system, the motors control, the lights etc., of the whole vehicle and orient the vehicle by pulling on the right steering handle 339 or the left steering handle 340, which fact pulls the driver and rotates with him the whole front wheel assembly so orienting the vehicle in one direction or

SUBSTITUTE SHEET the other. The center of gravity of the said three wheels vehicle with its loads is always maintained in between the central lines of the three carrying ground engaging wheels.

The orientation of the vehicle could also be made as follows:

(A) By providing the vertical shaft forming part of the joint 334 on the fourth part, with a gear system in combination with a set of gears (not shown) combined with a steering wheel operated by the riding driver. (B) By installing a flexible tie connected to the right panel 301 at one end, rolled at the left side of a pulley located below the driver's seat and extended forward and rolled around a second pulley mounted on a rotatable vertical, central shaft connected at its upper end to a steering wheel (not shown).

A second flexible tie is connected to the left panel 302 at one end and rolled around the right side of the forementioned pulleys in the same way as described for the first tie, and by rotating the said steering wheel, one of the strings is rolled around the front pulley, while the other string is unwinding, pulling the front wheel assembly closer to one panel or the other so changing the direction of the vehicle.

The fourth part could be made of two spaced front wheels (not shown) with a separate rider each, and connected with a solid horizontal rod, hinged at both ends, keeping the steering wheel with either one of the front riders.

All the wheels of the vehicle are provided with a separate standby motor, engaging the carrying wheel through speed variation and forward backward system to be used when necessary.

On an uphill drive the front wheel assembly and the two rear wheel assemblies of the vehicle slid along their supports to get closer to each other to give the vehicle a better strength in its uphill drive, and on a downhill drive, the front wheel and the rear wheels of the vehicle are slid on their supports far apart from each other to give the vehicle a better stability on its downhill drive.

SUBSTITUTE SHEET An additional wheel and pedals assembly similar to the right and left wheel assemblies, is added in the back at the center of the vehicle, rotatably connected to the rear central hinges 311 with provisional ties to the right panel and to the left panel, to accommodate two additional riders, raising the total number of riders to seven riders, (see fig. ID).

Usually the ground engaging wheel on the said fifth part is equally or more powered than the similar wheels on the said second part and the said third part, where the said fifth part could be left free to pivot around its hinges.

When the front ground engaging wheel on the said fourth part is turning to the right for example, the rear ground engaging wheel on the said fifth part would be pushing the back of the vehicle towards the le t, so giving the vehicle a dual steering mechanism.

When the rear ground engaging wheel on the said fifth part is under powered, the said fifth part would be equally spaced from, and connected to the said right panel and to said left panel, keeping a parallel alignment with the said second part and the said third part.

When not in use, the so described three wheel vehicle could be folded by releasing the ties and pulling the front and the rear panels inwardly towards the center of the vehicle bringing the right and left panels flat closer to each other spaced only by the thickness of the folded front and rear panels, reducing the overall size of the vehicle to less than five feet in length, about one foot in width, and about three feet in height, made usually of light weight metal weighing altogether about 30 to 50 kilos.

The folded three wheel vehicle could be pulled to the elevator, taken up to the office, partly open and used as a side table.

Going on a picnic, the vehicle could be kept open, fitted with a canvas cover and used as a bed.

In rainy seasons, the posts 341 would be raised, joined with a rope all around and covered with a foldable light weight cover forming a roof over the said vehicle.

SUBSTITUTE SHEET To put in service, the vehicle is unfolded by pulling the side panels apart, the front panels forward, the rear panels backward, resulting in a boat shape vehicle, before setting the ties 313, 314. The side panels are pulled far apart, enough to have a stable vehicle that would not lean when loaded on one side without the other.

The two sections of the front panel and the similar seσtions of the rear panel are inclined downward towards the right panel and the left panel so transferring the loads from the fourth part and the fifth part to the lower sections of the right panel and the left panel, and reducing the lever arm effect of the fourth part and the fifth part acting simultaneously on the right and left panels, and consequently giving the vehicle a better stability against overturning.

Two small additional wheels, commonly known as training wheels, are installed, usually in front of the right panel and the left panel, inclined outwardly, (not shown) and kept slightly above ground so that, if the front of the vehicle leans towards the right or the left, one of the said training wheels would touch the ground and prevent the vehicle from overturning to the right or to the left.

It is advisable to keep the vehicle equally loaded on both sides ._

When required, the side panels are provided with telescopic extensions at the front and the rear of the vehicle, lined with a canvas all around in the shape of a pick-up truck to be used for luggage and the like. In certain cases, the right and left panels are made longer to accommodate additional seats in between for passengers unable to pedal.

The hand cranks, the front foot pedals and the rear foot pedals on each of the 2nd and 3rd part, are interconnected, transmitting their actions together to the ground engaging wheels. The interconnection of these pedals and cranks is made by: (A) Tying the extreme ends of the arms of the hand cranks

SUBSTITUTE SHEET to the extreme ends of the arms of the front foot pedals usually with detachable flexible ties provided with a short spring as means of connection tolerance.

(B) By connecting the rear foot pedals to the front foot pedals with detachable solid ties in the same way as described for the hand cranks.

(C) By using separate gear system for the rear foot pedals combined with the front foot pedals using conventional known methods. 7-2 (See figs.2A, 2B, 2C, 2D, 2E)

7-?-l Figs. 2A to 2E show the details of a bi-energy four wheel vehicle partly or fully powered by the folks riding it, adapted to roll on rail tracks as well as on paved roads, comprising a chassis supported on a minimum of 4 wheels and supporting a platform 401, said platform in turn supports a plurality of longitudinal supports 402 by means of typical saddles 423. Each of the said continuous supports 402 support in turn:

A) A series of foot pedal systems like the assembly 405, 406, 407.

B) A series of hand crank systems like the assembly 408, 409, 410, mounted on the posts 415.

C) A rider seat 413 supported by the posts 414.

The hand crank right arm 409 is connected to the corresponding foot pedal right arm 406. The hand crank left arm 410 is connected to the corresponding foot pedal left arm 407.

The series of the foot pedals are connected to each other by means of solid rods 403, 404, which solid rods transmit the action of each group of foot pedals, together with the action of the hand cranks, to front and rear gears

416, 416B.

The typical front gear 416 transmits its rotation with speed variation through a chain 417 or other conventional means to a gear 418 fastened on a front shaft 419 and in turn to the front wheels 420 and caused them to roll forward or backward as the case may be. A similar transmission system activates the rear wheels of the vehicle.

SUBSTITUTE SHEET The inner rims of the wheels 420 are provided with steel rings with slightly smaller diameter than the rubber wheels, protruding inwardly to enable the vehicle to roll on rail tracks while the outer rubber wheels would enable the vehicle to roll on normal paved roads.

The central gear 416A is provided with two chains 417A, 417B connected to gears 418A, 418B.

Said gears 418A, 418B are combined with grooved pulleys pressing around cable 422. Said cable 422 is fastened to ground supports and is used in combination with the said grooved pulleys as traction means for the vehicle while guiding the said vehicle at the same time. The traction means could be:

(A) A flexible, inextensible cable, a chain, a solid track with teeth to engage a rotating gear is fastened to ground supports at a short distance above ground.

(B) A cable, a chain or a solid track as in (A), fastened to a ground support sunk below the level of the road paving, with enough opening to allow the passage of the engaging pulleys and the cleaning handle.

The chains 417A, 417B" together with the gears 418A, 418B, and the traction means 422 represent an optional assembly added to the vehicle.

The orientation of the vehicle is carried on by conventional methods used—for four wheel drive vehicles or the like.

The resultant four wheel vehicle is provided with a separate standby motor connected through speed variation and forward backward system, to the front and the rear shafts (not shown) to be used when necessary.

The said four wheel vehicle is provided as well with a cabin and conventional, additional accessories used for normal passenger vehicles.
