Description

The proposed device relates to scooters and is intended for use by healthy adults of any age as both a means of transportation and a hand trainer, as well as a traditional scooter.

Thus, the areas of application of the utility model are human health and the organization of its movement.

Known devices - scooters, the fields of application of which are human health and the organization of its movement; for example, a Fliker “F3” scooter containing a horizontal foot pad, a steering rack with a steering wheel and three wheels connected to it. The disadvantage of this device is that for its movement it is necessary to push off the ground only with your feet, while your hands hold the steering wheel and are not physically stressed.

Closest to the proposed device is a Scooter (Russian Patent for the invention 2418708 (13) Cl, registered in the State Register of the Russian Federation on 10/07/2009), containing a horizontal foot pad, a steering rack with a steering wheel connected to it, two wheels and a front-wheel drive the wheel by means of one or two functional devices containing exhaust belts associated with the scooter wheel having mobility “up and down”, and the second ends wound onto the drum of the clutch with a return spring mounted on the axis of the front wheel. The driving stroke of the drive is the movement of the steering wheel "towards itself", while the drive gives an additional impulse to the scooter, which makes it less likely to push legs off the ground. The disadvantage of this device is that the drive to the front wheel has an auxiliary character, determined both by the feature of the drive device and the presence of two wheels on the scooter; however, the device does not solve the problem of organizing independent movement without legs and is a simulator for the hands.

The technical problem solved by the proposed device is to ensure its use by healthy adults of any age at the same time as a means of transportation, and as a simulator for arms and legs.

The solution of the problem in the proposed device is that the device, the operation of which is illustrated in the figure shown in Fig. 1, contains a horizontal platform for the legs, a steering rack with a steering wheel connected to it, at least three wheels and a drive, has distinctive signs, namely, the drive is connected to the rear wheels, contains two sprockets mounted on the axis of the rear wheels without the possibility of their movement relative to this axles, rear wheels are mounted on an axis without the possibility of movement and rotation relative to this axis, two elements in the form of a disk or its parts are located on the steering wheel, located symmetrically on different sides of the steering rack and freely rotating relative to the axis of the steering wheel, to each element in the form of a disk or part thereof, the ends of the cables of two identical drive branches consisting of a series-connected cable, a bicycle chain, and a spring are attached, and the spring is attached with its free end to the foot platform near the steering rack, each drive branch extends from disks to the sprockets under the foot platform so that each cycle chain is constantly engaged with its sprocket in such a way that the stroke of the sprockets corresponds to the forward movement of the device back in the process - translational motion of chain circuits, provided by alternating or simultaneous manual rotation of the discs, "towards you", and the position of the steering wheel during rectilinear movement can be fixed mechanically and released when the device is rotated.

A schematic representation of the proposed device is presented in Fig 1. The proposed device includes (Fig 1):

1. - A horizontal platform for legs.

2. - The steering rack.

3. - Steering wheel

4. - The front wheel.

5. - A persistent level.

6. - Turn limiters.

7. - Elements in the form of a disk or part thereof (hereinafter “disks”).

8. - Pens.

9. - Drive branches, each consisting of a series-connected cable, bike chain, spring.

10. - Mounting units for springs.

11. - Swivel casters.

12. - Asterisks.

13. - The rear wheels.

The operation of the proposed device is as follows: On the axis of the rear wheels 13 are two sprockets 12 so that excluded the possibility of their displacement or rotation relative to this axis; while the stroke of the sprockets corresponds to the forward movement of the device. The free end of each cable of the drive systems 9 is fixed in certain places freely rotated on the axis of the steering wheel of the corresponding disk 7. The cables of the branches of the drive 9 pass down through the rotary rollers 11 and under the horizontal platform for legs 1 and are replaced by chains, each of which is constantly engaged with its own an asterisk.

Each of the two bike chains behind its “own” sprocket is connected to one end of the spring, which is attached to the spring attachment points 10 located under the horizontal foot pad 1 near the steering rack 2. The device is moved by simultaneously or alternately turning the disks 7 with their hands to the side, corresponding to the stroke of both sprockets (with simultaneous rotation of the discs) or one sprocket (with alternate rotation of the discs).

The fundamental moment of the drive’s operation is the reciprocating motion of the circuits in constant contact with “their” sprockets. This circumstance imposes coordinated restrictions on the angles of rotation of the disks 7, the lengths of the cable sections, the length of the chain, the characteristics of the springs, namely: all of the above components must ensure that each of the chain circuits pass through their own sprockets along the paths as close as possible to the length of the chain but exclude:

- the possibility of cycling out of engagement with asterisks;

- the possibility of contact of circuits with rotary rollers 11;

In addition, in order to limit the maximum allowable rotation of the disks 7 during the working stroke, a horizontal stop bar 5 is attached to the steering column 2 in the right place, and the rotation limiters of the disks 6 are fixed on the inner surfaces of the disks 7, which, when the maximum allowable rotation is reached, touch the stop bar 5 and further turning becomes impossible.

The constant tension of the elements of the branches of the drive 9 is provided by the springs of these drives; in this case, thanks to them, at rest, the disks 7 of the proposed device abut against the rotation limiters of the disks 6 against the retaining plate 5. The position of the rotation limiters of the disks 6 and the retaining plate 5 are selected on the basis that the springs remain in a somewhat extended state even when the device is at rest.

In order to eliminate the turning moment on the steering wheel when the device is moving in a straight line, it is advisable to fix the position of the steering rack, and if necessary, turn it to unlock the signal from the steering wheel.

Thus, the proposed device allows movement through the hands of a person standing on a horizontal platform for the legs, providing a combination of movement with training of the muscles of the hands.

An additional useful functional quality of the proposed device is the possibility of its use without any technical changes like a traditional scooter. For this, it is enough for a person to stand on a horizontal platform for the legs, grab the wheel with his hands and, as usual, pushing with his legs, move forward; in this case, both sprockets 12 will be in the free-wheeling phase and will not impede movement.
