The invention relates to vehicles driven on muscle strength.

Famous scooter (patent RU 2009941, WM 1/10, 1994), driven by muscle force, containing a base, a front wheel, leading the rear wheel, driveline with overrunning mechanisms supporting pad foot rollers for movement on the base.

The main disadvantages of specified scooter are: 1) a sufficiently large weight of the scooter due to its massive base; 2) low conversion gain muscle energy into energy of motion. The movement of the scooter by pushing the foot support areas, the result is a reaction that should be compensated by the muscles of the hands, and this is an additional burden on the person, resulting in lower efficiency of conversion of muscle energy into energy of motion.

Known vehicles driven by human muscle force (patent RU 2160681, 2160682, 2160683, WM 1/04, 2000). The vehicle according to the patent RU 2160681 contains a frame mounted on it the steering wheel from the steering fork, front wheel, rear wheel, mounted on the drive axis with a pair of overrunning clutches, a pair of actuating levers, a pair of flexible rods, the intermediate pulley and additional overrunning clutch Assembly.

The main disadvantages of this vehicle are: 1) when coasting Pref is derivative levers with the platforms go down and installed in an inclined position, in the socks, the feet are lifted, which creates an uncomfortable condition for the legs and at the same time loosening the moment; 2) the fastening of the flexible rod to the drive lever close to its middle, which reduces the length of the mileage of the vehicle compared to if the mount is flexible rod was moved to the end of the arm; 3) high landing increases the chance of falling and injury; 4) planting of a person is done by moving the legs through high installed frame, which reduces its use by the elderly and children; 5) the design complexity associated with the tangling of the cable when moving the vehicle back the progress. In the proposed impede reverse is possible only when a person standing on the ground, it will move in the rear direction. In this case, all the variants sloped shift the drive wheel in the rear direction jammed overrunning clutch, which is stronger pull cables, but since the drive levers are raised and rest against the Adjuster lift, the wheels just stop spinning. Move sloped reverse, in this case, the only possible method of slippage of the rear wheels or just lifting and carrying. Having small dimensions, weight and high maneuverability to samapada you don't need reverse.

Famous bike (patent US 1258391 And 05.03.1918, lass: 280/251), taken as a prototype, containing a frame, connected with it by the steering fork with the wheel installed on her rack with pulleys, front wheel, leading rear wheel mounted on a drive axis with a pair of hrapovic mechanisms, a pair of actuating levers, each of which is a front end pivotally mounted on the frame and has a platform, a pair of flexible rods, each of which is attached at one end to the drive lever, the other end, comprising a pulley mounted on the ratchet mechanism.

The main drawback of this bike is: 1) a weak spiral spring (17-17')installed on the rear axle and connected with the ratchet that has no body and is wound from round wire. The drawback of such springs is that when the tension she goes awry, i.e. external coils are closer to the axis, intersecting and stretching out between the inner coils. Typically, these springs are made of a plate material of rectangular cross-section that does not effect klineline and accordingly tangling. Such springs do not possess great effort and efficiency, and that the bike must be returned in original condition not only to ratchet, but also to raise drivers, which is impossible; 2) uses a ratchet mechanism, the ratchet wheel which creates additional friction and neither is coastally noise.

The invention consists in that sloped containing frame connected with him steering fork with the wheel installed on her rack with pulleys, front wheel, leading rear wheel mounted on a drive axis with a pair of hrapovic mechanisms, a pair of actuating levers, each of which is a front end pivotally mounted on the frame and has a platform, a pair of flexible rods, each of which is attached at one end to the drive lever, the other end, comprising a pulley mounted on the ratchet mechanism, it is equipped with return springs mounted on the hinge actuating levers and overrunning clutches, replacement ratchet mechanisms.

In addition, sloped provided with two curved grooves connected to the frame, with installed rollers, rods connected at one end with the actuating levers, and a second end with rollers and a flexible shaft.

In addition, on any of the points of the platform are adjustable base.

Use samoyede return springs, and overrunning will increase its efficiency and performance. The use of a curved chute with rollers and rods will allow you to combine a flexible rod with free ends of the rods. Thus arose the possibility to remove the high rack and to protect the rider during boarding and disembarkation, especially children.

Front lays 11 platform is RMI has the ability to reinstall (move) to fit under the foot of an adult or child (adjustable base).

Figure 1 shows the variant of sloped with stand and pulleys; figure 2 is a top view of figure 1; figure 3 - option with gutters, rods and rollers; figure 4 is a top view of figure 3; figure 5 presents a single node connecting rod mechanism.

Sloped consists of a frame 1 mounted on her steering with 2 steering fork 3, a hand brake, consisting of a handle 4, a cable 5, the pads 6, the front wheel 7, the leading rear wheels 8, a pair of actuating levers 9 with return springs 10, each of which has an adjustable platform with a front 11 and rear lugs 12, 13 hours, fitted with pulleys 14, through which spanned flexible rod 15 connecting the ends of the actuating levers 9 with overrunning clutch 16, a torsion spring (not shown)is pressed on the axle 17 protection 18.

In the variant with the crank mechanisms sloped contains two troughs 19, in which are mounted rollers 20, which are connected to rods 21 and a flexible shaft (cable) 15, and a yoke connecting rod mechanism serves as the drive lever 9.

According to the same schemes can be made three-wheeled variant of sampada. In this case, will be leading both rear wheels.

The movement on samepage as follows. Holding the steering wheel with 2 hands, the left foot is placed on the left of the platform 11, 12 of the lever 9, and then, pushing off the right leg from the ground, move your body weight on the left leg, the right leg with the habim on the right platform. Under the weight of the body, the left arm goes down. At this time, the flexible rod (cable) 15 through the pulley 14, razmahivati with clip - pulley overrunning clutch 16, sticking axis 17 and causes it to rotate together with the wheels 7, 8. Sloped moves a certain distance. Transfer the body weight on the right leg, straightening it in the elbow. In this situation zakladivaetsa videos right overrunning clutch, the movement of sampada will continue. At the time of prestuplenie legs, the left arm goes up by the spring 10, the cable 15 under the action of the spring overrunning clutch is wound on the pulley - ring overrunning clutch 16, the clutch gets a pass. Move levers 9 up limited Adjuster lifting levers (not shown). At any time, at any height, you can stop prestuplenie, both overrunning clutches will receive overtaking, and sloped will continue coasting. At any time, at any height, creating pressure on the platform, you can increase the speed. To stop samapada you must click on the handle 4, there will be a braking wheel stop and sloped.

According to the described technology movement is carried out and three wheeled samoyede.

In comparison with analogues and prototype sloped improves the efficiency of use of human energy at a sufficiently high speed of movement.

In samapada desirable to use telescopics the CSO steering, which is set at the optimum height when riding and is folded during transport and carry.

Sloped as a vehicle occupies a niche between scooter and bike [SELF(cat) and (%)PED] or scooter pedal. Possessing qualities scooter - low rise, high maneuverability and qualities of the bike - the transmission of torque to the leading of the rear wheel through moving platforms - pedals, sloped provides new opportunities for movement on the spatial surface of the earth. Vertical translational movement of the platform allows to use the weight of the person by means of elementary prestuplenie legs for movement. The transformation of the muscular energy of the person's feet with maximum use of gravity of the person in the torque of the wheel indicates the high efficiency of this device. Standing posture while moving together with the low rise will allow the use of sloped all age groups of people. Sloped has a simple structure, small size, weight and high maneuverability, which gives him the advantage of movement in a limited space, such as a movement on the sidewalks, exhibition halls, workshops, etc. Sloped simple to manufacture, has a low cost, making it available for the major bulk of consumers. Sloped not require a Parking space, it can be easily transferred manually.
