(57) Abstract:Usage: sports equipment for training coordination and entertainment. The inventive smartroller has a resonant energy storage with space for placement of the user. The drive associated with the possibility of rotation from the efforts of the user and kinematically connected with the propeller. The latter is in the form of at least one drive wheel. The drive is connected with the sprocket wheel through the freewheel. Between frame and drive posted by elastic elements. The device also has a means of inclusion in the job or off the leading link freewheel. When the vertical swinging of the user from the resonance of the drive energy of the impulse force is transmitted through the swinging lever and the chain transfer on the leading link freewheel and forth on the drive sprocket. When the periodic switching on and off of the leading link freewheel on it passed the energy stored rocking system for several idle cycles rocking. 1 C. p. F.-ly, 2 Il. The invention relates to subjects that meet vital human needs, and can be used as is, oladeji, as a means of entertainment for adults and children in places of organized recreation (in sanatoriums, tourist centers, parks, culture and sports equipment and means of transportation for people with disabilities with different lesions of the musculoskeletal system, but for cases where the disabled person can perform squats.Known smartroller containing a frame, a carrier propulsion and space, turning from the stress of standing on her user and kinematically associated with the propeller through the freewheel, and elastic elements to return the site to its original position.The known device is not capable of translational movement by a vertical resonant swinging user.The objective of the invention is the provision of a translational movement by the accumulation of energy in the system resonance energy storage by vertical swinging of the user and the discrete transfer this energy to the propulsion and the creation on this principle, a new sport projectile.This object is achieved by transmitting a pulse of force developed by the user at each downward movement in a vertical rocking or nakopleniya has a frame with the propeller, performed at least one drive wheel; a resonant energy storage device; a platform for placing the driver in a standing position, fixed on the frame by means of energy storage and kinematically associated with the sprocket wheel through a freewheel; and an elastic element for returning the site (together with the user) to its original position.Smartroller also has a device for switching on and off of the leading link freewheel.To improve the stability of the user at the site of the resonant energy storage device is fixed at one end through the elastic members, and the other end pivotally attached to the chassis through the axis. During vertical swinging system "user resonant energy storage device with elastic elements in each cycle, the user informs the system some momentum force, increasing with each oscillation amplitude (storing energy). Including periodically leading link freewheel, the user transfers the stored energy to the drive sprocket, which in turn converts it into the energy of directed motion. When always-on coupling at its leading link submitted by Comparative analysis with the prototype and other similar purpose devices allows to make a conclusion, that smartroller containing a frame, a carrier propulsion and space, turning from the stress of standing on her user and kinematically associated with the propeller through the freewheel, and elastic elements to return the site to its original position, according to the invention has a resonant energy storage device, a platform mounted on the frame by means of energy storage, elastic elements are located between the frame and the energy storage unit and the propulsion device made in the form of at least one drive wheel.In addition, smartroller differs in that it has a device for switching on and off of the leading link freewheel.In Fig. 1 shows a two-wheeled version of smartroller with resonant energy storage device having a space for accommodating a user in a standing position and attached to the chassis through the axis, and elastic elements, General view; Fig. 2 a cross-section of smartroller on the rear wheel with freewheel and elements of the device to turn on and off the leading link freewheel.Smartroller contains the front wheel 1 (Fig. 1) with the steering control 2, the rear drive wheel 3 to freewheel, the second lever 6, made zuzelo with the sprocket chain transmission, swinging around the axis 7, are fastened to the frame 4. Resonant energy storage device 5 is fixed on the frame 4 with the axis 8 and the elastic elements (springs) 9, symmetrically relative to the longitudinal plane of symmetry of the frame 4. Pendulum lever 6 is connected with the resonant energy storage articulated through an intermediate element 10, and the driving member of the clutch through a chain drive 11, the sprocket 12 and the Cam coupling sleeve 13 (Fig. 2). Positions 14 and 15 marked the end position of the pendulum arm, and two-way arrow shows the movement of the sprocket chain drive.The device switching on and off of the leading link freewheel is located on the steering 2 (Fig. 1) the lever 16 with the cable 17 (Fig. 1 and 2), connected with the spring loaded lever 18. The lever 18 acts on the sprocket 12, moving it along the axis 19 within the gap And including at work or off through the Cam coupling sleeve 13 leading link free wheel 20.Work smartroller as follows.The user scatters with sportolaro, jumps on the ground resonance estimates the energy storage device with elastic elements. When exceeding the angular velocity of the leading link freewheel on the angular speed of the rear drive wheel 3, which is rigidly fixed to a driven element of the clutch, the wheel is transmitted through the swinging lever 6 impulse force developed by the user when it moves together with the space resonant drive down. To increase the speed of the translational movement is necessary to increase the oscillation frequency.Wheelchair variant of smartroller made in three or four-wheeled stable version (version). Disabled before dvigatelya progressive on sportallee, swinging vertically, squating, and then during the next downward movement includes overrunning clutch drive wheel.For the enforcement of resonance oscillations by type of swinging on a swing or trampoline user using the lever 16 turns off from work leading link freewheel 20 and swinging as would otherwise be idle, storing energy (increasing amplitude). Thus smartroller continues to move by inertia. And at the right moment the user includes leading link freewheel to convert the stored energy in the next pulse, providing postwatergate adjust the tension of the elastic elements 9 using strips 21 (Fig. 1). 1. Smartroller containing a frame, a carrier propulsion and space, turning from the stress of standing on her user and kinematically associated with the propeller through the freewheel, and elastic elements to return the site to its original position, characterized in that it has a resonant energy storage device, a platform mounted on the frame by means of energy storage, elastic elements are located between the frame and the energy storage unit and the propulsion device made in the form of at least one drive wheel.2. Smartroller under item 1, characterized in that the switching on and off of the leading link freewheel.
