ASSEMBLY:
We place by each other the taken out from cardboard of ski foots. We raise the handles of ski foots to perpendicular position and we protect in the most comfortable for user position. We base from seat frame on upper edges of pedestals of zips and we screw in in threaded bottom rubber joints funnels screw. We lean in turn the ski of foot so then, to to make possible the screw in in funnels of rubber joints remaining screws. We draw screw and vehicle is finished to use

RECREATION:
Treading enabling handicapped persons after inaccessible terrains walks for cripplehood trolley vehicle: sand, snow, water, forest etc.

REHABILITATION:
Treading during movement vehicle engages the considerably larger parties of muscles than during drive on cripplehood trolley. The necessity of smooth swinging from side on side engages the muscles of trunk, labyrinth forces to work. One of version of vehicle makes possible the fastening to special handles the legs near runners, which extorts the movements of legs during executing the next steps and the circulation of blood makes better in limbs superbly.

SPORT:
The treading vehicle makes possible the defeating in frames of sport rivalry the field routs about different degree of difficulty.

PRINCIPLE OF WORKING OF TREADING VEHICLE CHEOPS:
The moving by help of vehicle person treading it sits on similar seat to classic cripplehood trolley. To execute to front  movement has to tilt on right, to relieve right runner. Trick runner be becomes lifted on several cm over level of terrain. Attracting it moves for right lever, together with from seat, along at present burdened runner. It slides after special with very small coefficient of friction chracteristic runner. In the same time loaded runner puts out to front automatically. Indispensable to shift oneself along runner the strength depends from coefficient the friction after runner the zip exclusively and the inclination of terrain. The sbasis runner on what stands, has not on size of indispensable strength the smallest influence  to the person's shift from seat together with. It doesn't matter if it is sand, grass, snow, soft the ground, size of strength depends exclusively, or we go after flat terrain, or we climb after slope. This principal cause, thanks is which treading vehicle wins in terrain from cripplehood trolley. The kind of soil has in moment only influence the transfer of centre of gravity "going" from one runner on second, to to can execute next step sliding after runner second runner. The smooth capture of swinging from side on side, then the only difficulty in science the help the treading vehicle. When the barrier of fear be becomes defeated before overturning on side and they will stand up after so far inaccessible terrains the composed art of turning, walks for "runners" is a true pleasure. The dimensions of vehicle are well-chosen so, that in every moment of movement we are in state of durable equilibrium which acts our vehicle unusually safe, treading vehicle it looks on shaky mechanism, in practice only seemingly this vehicle is "self-stand-up".

CHANGING SEAT FROM TROLLEY ON TREADING VEHICLE:
It in this aim, was one should the seat of vehicle treading put in back position. To invade on protruding part of feet of vehicle with wheel of trolley treading then, so, to the seat of trolley found on height of seat of vehicle treading simultaneously. It was one should was then shift from seat on seat, fasten in handles foot or on footstool and button the belt of safety.

USING HELP OF SECOND PERSON:
It in of limited possibilities of movements of hands handicapped person, vehicle treading case can be pushed by healthy person and the advantages of vehicle be become kept. It near help second person was can execute after sandy threnody of, snow, the walks the forest bedding and different, not hardened regions, near what person's effort pushing, it is small and it depends from slope of terrain exclusively.

THE BUILD OF TREADING VEHICLE CHEOPS:
Treading vehicle be built from thin-walled steel tubes from seat from plywood or material. Steel runners the funnels of zip after which slide, be protected before dust and water elastic protections, which assures possibility of use in every field conditions. The height of seat be regulated in dependence from the user's height. The angles of inclination of seat be fit to the user's individual needs also.

THE CONSTRUCTIONAL DETAILS OF FIELD TREADING VEHICLE:
The general idea of construction and the principle of movement of field vehicle treading type the Cheops.
We get to front movement thanks inclination on side, on example trunk in trick, so to the centre of gravity shifted beyond axis of rotatory zips. Be basing on left ski we - relieve foot completely right ski - foot. Pushing lever left ski - alloys, we move to front. Loading ski - foot, after inclination whole team being somewhat over surface, movement executes to front thanks the team of strings coupling automatically. Next step can will execute after inclination on right trunk, when treading vehicle stands up on right ski - alloy. We will execute to front step trick then, lifted ski - foot.

THE CONSTRUCTIONAL POSSIBILITIES IN ASPECT OF MINIMIZATION OF MASS TEAM THE TROLLEY - THE CHASSIS.
The constructing the prototype field treading vehicle, in spite utilization of the simplest materials and the use of simple technology of realization, it showed the very profitable weight parameters. The works over use of materials be led from alloy of aluminium, about high stamina parameters at present as well as it will permit with utilization on string of coal fibres on achievement of weight of target construction on level 50% weight of prototype.

THE POSSIBILITY OF MOVING IN TERRAIN ON BY HAND THE DRIVEN FIELD TREADING VEHICLE:
Equipment of field vehicle of treading the and profile of methods walking after sand.
 To it walking after sand field treading vehicle was equipped to be in two ski - the alloys about surface of point of contact from sbasis 0,5 m2 every. Collapsing in sand permits to limit to minimum this. The flat surfaces of beach do not require the specialist necessary gear to defeating the ornate eminences. The lack of high obstacles permits to very small span of joints of rockers, which permits on transfer by small balancing-pole the passenger's weight the trunk. The movement to front and to the levers so many will be extorted by propeling,  joint from ski - the foot of chassis.

EQUIPMENT OF FIELD VEHICLE OF TREADING AND PROFILE OF METHODS OF WALKING IN FORREST:
To walking in forest , where we can encounter unforeseen obstacles, ski - foots should be executed from light grid construction assuring near minimum weight proper stability. The forest requires first of all the perfect manageability and the possibility of defeating the various unevennesses. It will assure us this the comparatively wide span of rotatory zips near reduced width the ski - the feet, which permits on larger angle of turn of chassis in one rotatory cycle.

OPINION OF EXTERNAL EFFICIENCY OF MOVING NEAR USE THE FIELD TREADING VEHICLE:
Definition of external efficiency.
The external efficiency of moving, it can kneading after passage the sbasis every mechanism be definite on basis of opinion of degree , or this walking, or going on wheels. All walking, about large surface of feet, leaving mechanisms the distant from me traces, on soft sbasis will be more always efficient from vehicles on wheels, the leaving continuous, deeply pressed trace.

WHOLESOME ADVANTAGES:
The clinical investigations of wholesome aspects of moving did not become with treading vehicle conducted yet. It however on basis of two-year tests of prototype vehicle, by person from paralysis the bottom limbs, was can affirm, that:

- it the treading vehicle stimulates to movement all these parties of body and the muscles which during drive circular trolley are  motionless.
- fastened to special handles of leg, the similar movements can execute automatically to movements of the man's legs walking.
- the nodding on sides stimulates the labyrinth as well as the upper parties of muscles of trunk, the moving of internal organs causes improving the peristalsis of intestines.
- during drive hands work engaging rectifiers and flexor . Palms do not get dirty during bad weather and they do not be subject on contact with dirts of sbasis.
-  vehicle permits to move in places, in which air has healing values, and so after beach and forest.
- by consciousness of possibility using right away so far inaccessible, it improves the persons' psychical mood using from vehicle .

SPECIAL EQUIPMENT:
1.Driving helping team, consisting from: the compressor , battery, pneumatic pressess and the system of valves.  The driving team permits in exacting the larger effort situations to extort the movement of zip for help of pneumatic press.
2.The set of skis and the brakes to growing the touristic skiing.
3.The "crayfish" to anti - drifting to field expeditions about large degree of difficulty
4.Put out bracket to enlargement on sloping slopes stability.
5.Notepad and tench  to facilitation defeating ornate eminences.
6.Waterproof protections on runners and zips.
7.Coupling for novice persons pull rod (facilitating moving, thanks automatic moving of loaded ski-foots to front).  

SPECIAL REALIZATION:
In special realizations were foreseen was according to individual dimension requirements as well as special equipment.
The possibility of realization of light aluminium constructions exists for children after consultation with doctor with leader about advisability such form of rehabilitation also.
