Description

The utility model relates to both motorization of vehicles and can be used to rehabilitate users suffering from pathologies leading to partial immobility, impaired ability to maintain balance, for users with muscle atrophy, contractures, cardiovascular diseases, complete or partial absence of one of lower extremities, as well as general healing of the human body. It is applicable in cases of cerebral palsy in patients, the back of bifid, suffering from a disproportionate weight in relation to growth, the absence of limbs that have been amputated, and other diseases.

For people with disabilities, movement is extremely important; it also supports the overall tone of the body.

Various types of bicycles and runbikes are known, equipped with and without electric motors. We are interested in the 3-wheel version, which is most suitable for people with disabilities.

Known electric bike https://amped.ru/, but it is 2-wheel and is equipped with a chain transmission between the electric motor and the rear wheel.

Famous 3-wheeled bicycles https://formand.ru/trehkolesnye-elektrovelosipedy/?_openstat=ZGlyZWN0LnlhbmRleC5ydTsxOTk0NTc1NjsyNTI3ODAxOTgyO3lhbmRleC5ydTpwcmV882688V8VVV2626VVVV2626VVVVV26 They are also not adapted for use by people with disabilities.

In US 4,798,395, a patient is located between the rear wheels of a therapeutic bicycle. However, the design is very cumbersome and inconvenient to control, place the patient on it, as well as storage and not motorized.

In the designs of exercise bikes Veloider, https://dcp-velo.ru/ and Angel Solo, http://www.angelsolo.ru/catalog/rehabilitation_bikes/, there are also a large number of disadvantages. Here is some of them:

- according to manufacturers, the range of users is limited to people suffering from cerebral palsy

- the user needs to be lifted to sit on an exercise bike, which is particularly inconvenient if it is large. This is very felt if the user weighs, for example, 50-80 kg or more.

- there is no adjustment of lateral stability of the exercise bike, and as a result, safe movement is possible only on a flat surface.

- these exercise bikes have a very large dynamic mass and a large weight, and this requires the application of tremendous forces both from the side of the user, which he usually does not have, to move the whole structure together with its own weight, and from people who should push him or bring him home.

- Large dimensions create inconvenience in use, everyday life, taking the product out to the street and storing it at home.

-limited number of settings for individual user features

-High and non-adjustable Center of Gravity.

- inconvenient to manage.

- complicated in disassembly / assembly.

- there is no damper on the steering column, and as a result, poor control of the rotation of the front wheel.

The closest to the proposed technical solution is the “PETRA racerunner” design, described in advertising booklets and on the manufacturer's website https://by-conniehansen.com/.

The design consists of a frame on which three wheels are mounted, one of which is equipped with a steering wheel, there is a seat and support for the user's chest. The design is also equipped with a brake. The user's seat is located near the rear axles of the three-wheeled vehicle or even above the specified axis. As our studies have shown, the weight distribution for each of the wheels of this design with a patient weight of 88 kg is: front wheel - 18 kg, each of the rear wheels - 36 kg, taking into account the weight of the vehicle itself 16 kg. Obviously, this circumstance is fraught with the rider rolling over backwards under any disturbances or obstacles in front of the front or even in front of the rear wheels. Since when raising the front wheel even by 5-10 cm relative to the rear wheels, or when receiving the impulse by the front wheel when hitting an obstacle and tilting the entire structure back, the bulk of the user's body weight is also transferred backward, going beyond the axis of the rear wheels and causing it to tip over. It should also take into account the overturning moment, aimed at tipping the vehicle back and acquired by the vehicle from the feet of the patient himself, pushing off the ground and. This can lead to personal injury. The danger of tipping over is also confirmed by the manufacturer, on one of the racks of their bicycles there are warning signs about the possibility of tipping bicycles back. There is no possibility of adjusting lateral stability, changing geometry, or other adjustments that increase both the area of application, the safety of using the bicycle, and the settings for the individual characteristics of the user. And also this design does not have motorization.

The proposed design takes into account all these issues.

The technical problem to be solved was the need to create a three-wheeled therapeutic electric bike, providing both motorization of the vehicle and the ability to be used to rehabilitate the vestibular apparatus, musculoskeletal system, strengthen the skeleton and muscles, improve the cardiovascular system, respiratory functions, cerebral palsy, bifid back , autism, metabolism of the body’s vital activity, etc. by creating an active load with the maximum amount of Wa settings for the individual characteristics of the user, as well as guaranteeing security for user patients. The proposed three-wheeled therapeutic electric bike can be used both outdoors, in parks, for driving on highways and on rough surfaces, and can be used indoors.

The technical result of the utility model is the motorization of a therapeutic tricycle vehicle for people with disabilities, as well as providing the maximum number of settings for a tricycle therapeutic electric bike for the individual characteristics of the user.

A three-wheeled therapeutic electric bike for people with disabilities allows you to move through the use of an electric motor, by pushing it off the ground with your feet without using an electric motor, as well as in a mixed way in which an electric bike helps the user to move forward by pushing it off the ground, and thereby, for example, allows Do not overload the user's muscular system. The thrust of the electric motor is adjusted by means of the control unit 50 Fig 2. The electric bike contains a front wheel 1 equipped with an electric motor 48 mounted on a front wheel fork 2 mounted in the steering wheel 3. The electric motor 48 is powered by a battery 49 and is controlled by a control unit 50 mounted on the steering wheel 4 . The steering wheel 4 is mounted on the fork 2, the steering damper 16 is connected to the stiffener 33. The upper pipe 5 contains a rotary stop 37 with a stopper 36 having the ability to rotate in the direction of the arrow F around the axis of the upper pipe 5, the hinge 34 connected to the shank of the upper pipe 35 on which the counterpart 38 is mounted, the clamp 8 and the fasteners 9 of the seat tube 10 with a saddle 11 mounted on it. The connecting pipe 6 can be located vertically or below the upper pipe 5 angle to the horizon. A change in the position of the center of gravity and the center of mass can occur due to a change in the angle of inclination of the upper pipe 5 with respect to the horizon, which is achieved by changing the diameters of the front and / or rear wheels. In figure 1, these movements are shown by arrows and the angle "C" is indicated. Another connecting element 14 is installed on the support pipe 12, which comprises a thrust support 13, which can be moved along the height of FIG. 1, FIG. 2 and FIG. 3 longitudinally along and rotates around the axis of the support pipe 12 of FIG. 2. The emphasis is removed in the absence of the need for its use. At the ends of the carrier pipe, connecting elements 14 are also installed, by means of which the rear wheels 15 of Fig. 1 and Fig. 3 are mounted. Details are described below and are illustrated in Fig. 6. The steering damper 16 is attached to one part of the stiffener 33. It is necessary to avoid sharp turns of the front wheel in the case of the patient having various types of spasticity, facilitating the management of the therapeutic electric bike and ensuring the stability of the direction of movement. Damper 16 is equipped with an adjustment of elasticity and can act as a limiter of the angle of rotation of the steering wheel. In the absence of need it is easily dismantled. On the steering wheel 4 can be mounted adjustable in length locking straps of the positions of the hands, equipped with elastic elements that are used if necessary. In the figures are not shown.

A rotary and collapsible footrest 47 of FIG. 1/1 is attached to the upper tube 5, which can be used when switching to the movement of an electric bike from an electric motor 48. Stand 47 is mounted in zone I, indicated in FIG. 1 and shown as II in FIG. 1 /1. The fasteners 44 may be connecting elements 14 or standard connectors at right angles to the pipes.

In the design of the electric bike, the projection of the clamp axis 8 of the seat tube 10 falls to the height of the triangle formed on the plane by the points of contact with the ground of the wheels of the tricycle therapeutic electric bike, and is located as close as possible to the center of gravity of the isosceles triangle. This allows you to maximize bring the main weight of the rider to the center of gravity and the center of mass of the entire design of the electric bike.

The stiffener 33 can be performed and installed in different versions. First, a connecting element 14 is installed on the steering wheel 3, through which an integral stiffener 33 of FIG. 2 can pass, or its prefabricated embodiment of FIG. 2/1. The ends of the stiffener 33 are interfaced with the carrier pipe 12 by means of rotary couplings 42, Fig. 10, which ensures both their dismountability, movement along the axis in order to select the optimal position, and rigid fixation in the selected position.

Thanks to this type of connection, it is possible to adjust the height and angle of the mating elements. Figure 2/1 shows a variant of a composite stiffener using connecting elements 14.

It is possible to pair the steering tube 3 with a stiffener 33, which in turn is connected to the support tube 12 by welding. This will reduce the number of possible settings, but will not remove them completely. In this case, it is recommended that the element 33/1 be welded to the glass 3 of FIG 2/1, and 33/1, and the ends of the parts 33/2 and 33/3 are connected to each other and to the supporting pipe 12 by the use of rotary couplings 42.

The saddle 11 is adjusted in height and longitudinal direction through the use of a seat tube 10, clamp 8 and fasteners 9.

The contact points of the wheels 15 with the earth form a triangle. Due to the properties of the connecting elements 14, it is possible to move the rear wheels 15 along the axis of the supporting tube 12, as a result of which the geometric dimensions of both the three-wheeled therapeutic electric bike and the triangle change, and this allows you to adjust the position of the center of gravity and the center of mass of the whole structure, taking into account your own weight and height of the patient. In addition, it is possible to change the angular position of the wheels 15 relative to the horizon, which allows you to adjust the lateral stability of the tricycle therapeutic electric bike, Fig.3.

The user support belt, adjustable in length and equipped with elastic elements 24 of FIG. 2, can be attached both to the support tube 12 and to the chest support 13. If necessary, two belts can be used simultaneously. The same belt as described in item 24 is used to hang one of the lower limbs of the user. It is also attached to the horizontal part of the supporting pipe 12. This is especially convenient for users with artificial prostheses, pushing from the ground with a healthy foot occurs in more comfortable conditions. All this has proved itself to be excellent in work, creating both a greater number of adjustments and increasing security conditions for a certain category of users.

Due to the fact that the steering glass, front wheel fork, bearings, fasteners, brakes are widely known standard products for bicycles, they were not displayed on the figures presented. The rear wheel brakes borrowed from wheelchairs are installed on the inclined parts of the carrier pipe. They are also not shown in the figures.

The principle of operation of the connecting element 14 of FIG. 4 is described in detail in patent No. 187938 and is shown by the example of the jointing of the docking pipe 6 and the supporting pipe 12. The clamping is performed by the fasteners 18, and the rotation is prevented by the latch 19, which is illustrated in FIG. 5. The connecting element provides the ability to quickly configure, dismantle / mount the therapeutic bicycle, as well as the reliability of the connection forming its parts.

The articulation of the quick sleeve 7 on the axis 20 of the wheel 15 is shown in Fig.6. Having released the fasteners 18, a quick-detachable sleeve 7 is released, which is fixed on the axis of the wheel, and, accordingly, it is possible to quickly remove the wheel 15 from the electric bike. Having released the fasteners 18, you can rotate the connecting element 14 around the supporting pipe 12 and change the position of the wheel 15 relative to the horizon. This is extremely necessary to adjust lateral stability based on, for example, the user's height and weight, as well as the convenience of storage, transportation, and skidding into and out of the room. electric bike.

If it becomes necessary to change the geometric dimensions of the carrier pipe 12, it is possible to manufacture it from several parts. Fig. 7 shows an embodiment of three components, designated 12 / 1.12 / 2 and 12/3, which form the element 12 using the connecting elements 14. Moreover, these parts can have different geometry both in cross-section and in shape.

To create increased rigidity of the carrier pipe 12, which can be demanded by both the conditions of the road surface and other circumstances, a quick-detachable stiffener 22 and connecting elements 14 are used. Closing the free ends of the carrier pipe, we create a rigid contour, thereby increasing the structural strength parameters.

An articulation of a quick-release stiffener 22 with a quick-release control handle 23 is shown in Fig. 7 and Fig. 8.

In cases where it is necessary to change the user's landing on a three-wheeled therapeutic electric bike, it is possible to use a support for the back 29, Fig. 9, which is equipped with a soft pad 30. A rod 27 having a groove 26 is inserted into the horizontal part of the seat tube, allowing the rod to be adjusted for takeoff followed by fixing the selected position using standard fasteners and hole 25. Groove 26 also guarantees the impossibility of completely removing the rod from the feed tube until the fasteners are removed from hole 25. W swarm end of the rod has an opening to allow interfacing with cylindrical articles, equipped with a slit and a standard clip 32. By this, the piston rod 27 is connected to the axle 28. The axle 28 is mounted on the connecting member 14 into which the support for the back. As a result, we get the opportunity to adjust the support for the back along the axis of the seat tube 10, along the axis 28, according to the angular position around the axis 28, as well as the reach and height, which allows you to choose the best position depending on the physical characteristics of the patient. The shape of the support for the back 29 may be anatomical. If necessary, you can use the fixing belt of the user 31, adjustable in length and equipped with elastic elements of Fig.9.

The use of overrunning clutches in the wheel hubs makes it easier for the user to hold the three-wheeled therapeutic electric treadmill when driving uphill and protects it from possible backward movement if the user has not had time to apply the hand brake. Couplings can be installed in the front, in one of the rear, or in all wheels. Depends on the type of track on which traffic is planned. In the figures, the hand brake is not shown, since it is a standardized product.

FIG. 10 illustrates the principle of operation of the rotary coupling 42. The method of clamping and fixing the elements / parts passing through its body is the same as that of the connecting element 14 described in patent No. 187938. The fundamental difference is that the connecting element is divided into two parts, indicated in FIG. 10 as 14A and 14 B. In part 14 B there is a recess 40 made in the form of a body of revolution, and in part 14A there is a protrusion 39 that mates with the recess 40. Due to this, the halves can rotate around a common axis. On the protrusion 39 there is a groove 41 and a hole for standard fasteners, which, for example, can be made in place. This ensures not only reliable fixation of the part, but also prevents the rotation of one part of the coupling relative to another. This ensures the reliability of the clamping of structural parts in the selected position. Such a coupling allows you to choose the correct position in space for fixing the mating parts, in this case 12 and 33.

The use of connecting elements 14 and couplings 42 creates great opportunities for the modification of a three-wheeled therapeutic electric bicycle.

FIG. 11 shows the upper pipe 5 with a rotary stop 37 mounted on it, equipped with a stopper 36 and an adjusting screw 43. The shank of the upper pipe 35 is equipped with a counterpart of the stop 38 and is connected to the upper pipe 5 by a hinge 34. The shank of the upper pipe 35 is also equipped with a seat tube and a saddle 11. Raising the stopper 36 up, release the pivot stop, rotate it around the axis of the upper pipe 5 and remove the adjusting screw 43 from the contact of the stop 38, view AA of FIG. 11. Floor. A - details pos. 43 and 38 are in contact, Paul. B - not in contact. Due to this, the shank of the upper pipe together with the sub-seat pipe and the saddle fall down, and occupy a position close to the perpendicular to the ground. Carrying out the operation in the reverse order, the saddle returns to its previous position. The screw 43 can be used to adjust the alignment of the axes of the upper pipe 5 and the shank of the upper pipe 35, which allows for additional adjustment of the saddle 11. This mechanism is designed to be able to bring a user with various physical limitations to a therapeutic electric bike, not to force the latter, for example, raise the leg to sit in the saddle, and bring the saddle itself under the user from the bottom up.

If it becomes necessary to increase the rigidity of the structure, it is possible to use stiffness stabilizers 46 of FIG. 12, which are connected to stiffeners 33 by means of connecting elements 44, which may be either connecting elements 14, couplings 42, standard pipe connectors at an angle or combinations between them. In option A of FIG. 12, the connection of the stiffness stabilizers 46 with the docking pipe 6 is shown. Moreover, due to the ability of the connecting elements 44 to rotate around the docking pipe 6 and moving them along the stiffeners 33, it becomes possible to select the optimal fixing position, which is marked as positive in FIG. And pos. B. In the embodiment of FIG. 12, the connection of the stiffeners 46 with the upper pipe 5 and the stiffeners 33 is shown. A similar connection is possible between the stiffeners 33 and the supporting pipe 12. It is not shown in FIG. Welding is allowed instead of using the connecting elements 44. But this limits the number of adjustments. Pos. 45 section I-I shows a collapsible embodiment of the stiffener 33.

To reduce weight in most of the design of a three-wheeled therapeutic electric bike. aluminum alloys, Kevlar, etc. are used.

Details and various parts of the bicycle are recommended to be painted or anodized in various colors, preferably bright. This will help create a chromotherapy effect for patients.
