The invention relates to a stabilizing device for a single-wheeled vehicles, in particular bicycles, driven by a rider.

Because of the presence of crossing roads when driving in urban areas often stop and re-start the movement. This mode of motion is normal for cyclists in cities and urban areas and can lead to potentially dangerous situations, when the cyclist must stop immediately, with the result that he may lose his balance.

Under these conditions, the motion of the cyclist at each stop must put one or both feet on the ground, and in many cases may be partially forced to dismount. Frequent abrupt stopping and starting of the movement are of great inconvenience for the cyclist. They can also be potentially dangerous due to loss of balance, impatient behavior due to the disorder of plans and so on, especially when there is movement involved heavy trucks.

The design of the bike and the physical parameters of the rider often lead to the fact that the saddle is set either too low to provide sufficient force on the brake pedal, or too high, so that the cyclist could stay in the saddle during a stop. This may cause the cyclist often dismount and get back on the bike.

The aim of the invention is to provide a stabilizing device for a single-wheeled transpire.

Another objective of the invention is to provide a stabilizing device which can be made in the form of adaptations to the existing single-track two-wheeled vehicle, or may form part of a two-wheeled vehicle in finished form.

For this stabilizing device for a single-wheeled vehicle includes a lever pivoted at one end at or near the axis of the wheels of the vehicle and having a degree of compressibility in the axial direction, a transverse axis, attached to the other end of the lever, a pair of stabilizers mounted on the transverse axis, the coupling element with the wheel located on the transverse axis between the stabilizers and the means for moving the arm between a raised position in which the stabilizers are not touching the ground, and a lowered position in which the stabilizers are in contact with the ground, and the wheel of the vehicle is lifted from the ground and coupled with the coupling element. Lever, a transverse axle and wheels it is possible, therefore, to consider the items that make up the backup. In accordance with the preferred option the wheel of the vehicle bespec of the present invention stabilizing device for single-track two-wheeled vehicle, which can be a bike, motorbike or motorcycle, contains compressible lever pivotally attached at one end to the frame of the vehicle at or near the spindle of the rear wheel can move in a plane parallel to the plane of the rear wheel, a roller on the other end of the lever and provided with a circular surface for coupling with the working surface of the tire and flanges, installed with the possibility of a snug fit to the opposite lateral sides of the tire, stabilizers installed on the specified other end of the lever with the possibility of coupling with the earth from opposite sides of the rear wheel, and means for moving the arm between a raised position, when the stabilizers are not touching the ground, and a lowered position in which the stabilizers are in contact with the ground and the rear wheel is lifted from the ground and connected with a roller.

In accordance with the preferred stabilizers are the wheels, and the device has mounted on the lower end of the lever transverse axis, on which the roller and stabilizers.

Most of the mass of the rider is transferred to the ground through the wheel trasportatori, you need to perceive only a very small fraction of the mass of the rider and therefore it can have a much lighter construction than in the case when the whole mass, usually transmitted to the ground through the wheel, would pass to the stabilising lever, as in the case of known stabilizers (German patent N 174152), which are on each side of the two-wheeled vehicle pivoted lever, passing with a slope in the direction from the frame of the vehicle and carrying a transverse axle on which there are widely spaced stabilizing wheels. Thanks to the transfer of weight through the wheel of the vehicle, weight is transferred to the stabilizer near the ground, resulting in forces caused by the tilt and so on, is extremely reduced. This allows the use of only one arm instead of two levers. The stability and stiffness of the stabilizing device is increased in the case of transmission through the mass of the roller, provided with flanges, as the lateral forces can be transferred between the roller and the wheel without any significant tension lever.

The lever is a spring-loaded telescopic arm mounted to rotate around the axis back to the starting spring, a gas spring or elastic material. In accordance with another variant, the lever may not be telescopic and can be installed eccentric relative to the axis of the rear wheels, and it can have an elastic means providing it with some degree of compressibility. The device can be configured so that it did not touch the wheel, while in the raised position, but gradually close to the wheel when lowering and took the bulk of the vehicle and the rider through the wheel, a transverse axis, and stabilizers.

In a preferred variant, when the coupling element with the wheel is fitted with flanges of the roller, the position of the flanges may be changed in accordance with different types and sizes of tires. In addition, can be selected other rollers.

The stabilizers are the wheels, although there may be used any suitable alternative items with low friction, such as rollers, etc.

Thus, the present invention provides the rider the ability to remain comfortably seated in the saddle at all stages of the process of stopping, waiting during a stop and then sending it to the path. It also helps the rider to maintain full cocalico the bulk of the rider is transmitted through the wheel of the vehicle and a transverse axis to roll the wheels, the lever takes only a relatively small load, the combination of a lever, the rear wheels and the transverse axis forms a rigid whole, can help to maintain the stability of the rider and the vehicle when the vehicle is stopped, although the rider may require the application of some small effort to maintain balance, as required from the driver of a single vehicle in any case.

Thus, the rider can omit the backup process stops, providing balance when he still continues to move forward, and backup can be instantly removed when sending in a further way. In the lowered position, both of the stabilizer in contact with the earth at the same time.

When approaching the lever to the fully lowered position of the rear wheel of the vehicle rises from the earth, while the vehicle is still in the process stop using the front brake. This gives several advantages:

1. The fact that the vehicle driver retains full control over it, helps to provide greater security for themselves and for other traffic on the road;

3. This allows the driver of a vehicle equipped with a mechanism for selecting the gear ratio, to choose the optimal transfer for departure on a long journey, in particular in situations where sudden stop made unusable the previous choice, because the rear wheel can rotate freely;

4. In those cases when it is more convenient, you can use the bike for a workout or at home, working the pedals in the static mode, when the support is lowered and locked in this position and the rear wheel raised.

It is obvious that the proposed two-wheeled vehicle may be initially manufactured as such or can be a modified existing design.

The present invention thus extends to those elements of the combination, which require necessary modifications.

Overall width of the stabilizing device with a fixed calessino lever position stabilizers provided (on a fairly level surface) is sufficiently stable support for the rider, allowing him to keep his balance, while stopping in the saddle. The preferred width is between 175 and 225 mm

The lever must be installed with the possibility of free radial swing with limited movement around the circumference of the rear wheel, preferably with sufficient clearance. When the lever is in the raised (fully retracted) position, the distance between the bottom edge of the stabilizers and the earth is about 150 mm or more, although if necessary, the lever may be held in any position above ground level.

In all cases, it is preferable that the lever is locked in the lowered position was at an angle to the vertical, which contributes to the removal of the stabilizing device back in his release. Such allocation of additional help by passing the forward wheel of the vehicle. It is desirable that the angle was small, presumably within 5-10aboutbecause it helps to provide stability when the lever is in a lowered position.

Backup can be omitted to enter it in contact with the ground and raise the rear wheel, using any of podobedom, on which it is installed, a means of lowering may contain a coil that the rider rotates, pedal back, and a flexible link, such as a chain or cable wound on the reel and connected to the lever preferably by attachment to the transverse axis. The coil may be located on the main shaft of the pedals between the pedal crank and the sleeve roller pedals or on the lower bracket on the side of the bike opposite the main sprocket drive chain.

The coil preferably is held at its periphery a groove of variable depth, which may be attached a flexible element wound on the coil cyclist by pedaling backward. The other end of the flexible link can be attached to the supplied flange ring on the transverse axis. Pedaling backwards, and the resulting wound flexible link provide lowering struts from its raised (allocated) provisions up until it will not come in contact with the ground and raise the rear wheel.

An important characteristic of the present invention, which guarantees fast action when lowering and retraction struts, is that the prop fully descended,social position, so that the connection of the flexible link is always under tension and upon release of the flexible link is as far as possible the fastest retraction struts ago. Usually the minimum ground clearance for the rear bike wheel in the raised position may be about 6 mm

The coil is preferably positioned near the roller pedal or the main drive chain. It can be positioned on the shaft or the crank adjacent the pedal with providing permanent attachment to them its core. The coil has a diameter sufficient (within the frame of the bike) to optimize the maximum speed lowering struts by pedaling backward, and torque is such that maximally reduces the extra pressure on the brake pedal, and a suit from the cyclist when lifting the rear wheel from the surface of the earth.

Width, i.e., the thickness of the coil should be kept to a minimum, providing the necessary structural rigidity of the coil and the ability of the coil to hold the flexible element in the groove and is typically about 9 mm, although it can be changed in accordance with the specific circumstances, but usually it is set such that the coil is S="ptx2">

The flexible element is preferably secured in a circular groove of the coil in place the minimum depth of the groove, and the depth of the grooves do such that when the winding of the flexible link in the rotation of the cyclist pedals backwards, the depth of the grooves has grown rapidly. This provides increased application of torque to the prop via a flexible link without requiring a corresponding increase in the pressing force on the pedal cyclist at a critical moment, when the wheel supports are in contact with the ground and the rear wheel comes in contact with fitted with flanges of the roller and rises from the earth.

Preferably the coil core hit a jam on on the main shaft of the pedals or crank and perform so that it meshed with the main part of the coil and rotated only during the rotation of the cyclist pedals backward, allowing the winding of the flexible link and lowering struts.

Thus, the main part of the coil carry out so that it does not rotate, when the rider rotates the pedals in the direction of forward movement. This can be achieved by embedding between the core and the main part of the coil sisla, educated at the core on the surface of its junction with the main part of the coil as the freewheel. Dogs preferably interlock with teeth only when pedaling backwards.

The main part of the coil is free to rotate in the forward direction within the length of the cable, i.e. in accordance with the rotation of the pedals in a forward direction after release and, therefore, allows a flexible link to get away from the coil that allows the prop to rise in its fully raised (reserved) position. This free-wheeling device is the preferred alternative to the system of the coupling or couplings (or dogs that require actuation by the rider) and enables instant lowering struts. This may be necessary, in particular, when the cyclist should sharply to stop. The movement can be further accelerated due to the previously mentioned progressive nature of the coiling action of the coil.

The coil is closed partially or substantially stationary casing, which is rigidly attached to the sleeve roller pedals and/or to a suitable point on the adjacent frame elements. The casing serves to protect katestone, when it is used.

As a means of automatically locking the supports in a lowered position raised from the ground by the rear wheel can be provided by a spring-loaded latch same as that of the coil, the thickness (width). It can be installed on the fixed casing and can be entered in the notches of corresponding shape in the periphery of the coil, when it will be fully lowered position. The latch may be released by means of a cable and is conveniently located on the frame lever to release the coil, allowing retraction struts ago. To commit fully lowered position may be provided with a suitable stop, which can be mounted on the fixed casing or may be made in the form of a tube on the flexible link.

The latch feature also with the possibility of introducing her to the second set of notches in the periphery of the coil, when the flexible link completely comes off the coil and backup reaches the end raised (allocated) provisions. This second locking prevents the tendency of the coil to continue unwinding beyond the desired point and provides some necessary compression or tension in a reactive stance when pdpo the next rotation of the coil, there is an automatic release of the latch in the second position. May be provided by a series of cuts.

To allow instant removal of props back to the cyclist could move from place to stop forward, use a mechanical spring or some other reactive means, such as gas. Possible design tools allotment contains the knee-lever mechanism, passing between the lever at a fixed point on the Bicycle frame, and a spring for expanding the knee-lever mechanism.

In accordance with the invention can be created backup with wheels that can be quickly lowered to the ground, while the vehicle is still moving forward in the process of stopping that gives the rider the ability to maintain balance and provides full control of the vehicle by grabbing hands of the steering wheel and the adjacent brake levers, while remaining in the saddle and holding the feet on the pedals.

The present invention can also contribute to safety and a more comfortable ride thanks to a simple sequence of operations in the process of stopping, while at the stop, and when sending forward with the surrounding area, holding hands on the front brake lever;

2). By limited rotation of the pedals backwards, wrapping the flexible element, one end of which is attached to the coil on the shaft of the pedals or in the vicinity of the opposite main chain drive side and the other end attached to the support, containing a transverse axle mounted on the lever, pivotally attached to the Bicycle frame near the hub of the rear wheel. The coil is made with quick coiling flexible link for quick supply of wheels on a transverse axis to the ground and lifting the rear wheel of a Bicycle, sufficient for it (wheels) free rotation. In this position it is automatically locked by appropriately installed latch;

3). Departure from designated stops and instantaneous diversion struts ago by snapping installed near the handle on the handlebar lever, through which the cable opens the latch, releasing the coil and, hence, prop. Backup immediately given back and the latch is automatically included in the second pair of notches on the periphery of the coil latching coil in a fixed position.

Some possible designs of the bike can be used on the same to have a backup for Parking, which facilitates the approach of the cyclist on the bike and subsequent departure.

In Fig. 1 shows a side view of the rear of the bike with the parts, and the stabilizing device shown in the lowered, i.e., working, position, and Fig. 2 is a side view of the rear of the bike, the stabilizing device shown at the top, i.e. non-working position; Fig. 3 - section a-a in Fig. 2; Fig. 4 is a cross-section of the coil, which forms a part of the stabilizing device of Fig. 5 - section b-B in Fig. 4; Fig. 6 is a section view similar to Fig. 3, but illustrating a modified construction.

The rear part of a Bicycle includes a rear wheel 11, the sleeve 12 of the rear wheels, the tire 13 of the rear wheels, two seats 14 of the saddle, two supports 15 chain, crank 17 of the pedal (Fig. 4) and the roller 18 of the pedals. These parts are connected together in the usual way. The rest of the Bicycle frame and most of the details are not shown. In this case, the details of the transfer are on the far (Fig. 1) side of the frame and include installed on the spindle of the wheel drive sprocket 19, which in practice is usually part of a multi-stage transmission type derailer.

In addition to the standard components, the bike sod is 25, one end of which is pivoted on the axis of the rear wheels, and the other end provided with a fixedly mounted thereon a transverse axis 26. On the transverse axis 26 is installed with the possibility of free rotation of the two wheels 27.

As shown in Fig. 1-3, the telescopic lever 25 is fixed only on one side of the hub of the rear wheel, allowing it to avoid complications with deriere or other mechanisms, gears, and freely rotated on the bracket 71 attached to the frame near the sleeve. The bracket 71 includes a vertical plate 72 having a hole axis of the rear wheel and fixed to a pair of clamping plates 73, which cover one of the pillars 15 chain and clamped to the support by means of two nuts and bolts 74.

On the axis 26 has a roller 51, containing the drum 50 with a ribbed surface and the flange 52. The roller is installed with the possibility of free rotation and comes into effect when translating struts 21 in the fully lowered position. The roller 51 takes the bulk of the bike and its rider in the locking of the telescopic lever 25, the lever 25 plays a supporting role in the perception of the load and helps the rider to maintain balance when stopped.

Overall width of the two wheels 27 is typically about 200 mm, It is desirable optimal value for normal use, although in practice the wheel 27 can be used for certain applications are posted and more.

The design of the device ensures the continuation of the basic load transfer through the rear wheel 11 of the bike on the roller 51 and thence through the two wheels 27 of the device on the road and the lever 25 always plays a supporting role in the perception of such loads.

The flanges 52 on the roller 51, densely covering profile tires provide Centrino is replaced by a roller, having a different distance between the flanges 52, or it can be made adjustable. The flanges provide the lever 25 lateral support and reduce lateral forces due to the effect of circuit supports for the rear wheels 11, resulting in the lever and the rear wheel act together in case of accidental tilting of the Bicycle when the device is in a lowered position, and the rider still sitting on the bike.

Telescopic lever 25 includes an outer tube 55 of circular cross section, which is pivotally attached at its upper end to the bracket 71, and the inner sleeve 56, which is telescopically enters the pipe 55. At the lower end of the sleeve is provided with a plug 57, which is rigidly attached to the transverse axis 26. The tube 55 has a lower end fixedly mounted to the flange 58, and between the flange 58 and the upper part of the fork 57 is installed spring 59 compression, covering the lower part of the sleeve 56. To prevent rotation of the sleeve 56 in the pipe 55 is provided protruding from the bushing pin 60, sliding in a longitudinal groove 61 in the pipe 55, which also limits the movement of the sleeve 56 in an outward direction, providing retention of the sleeve in the pipe. A second spring (not shown) compression takes place between the upper end of the sleeve 56 and the concentration is adjusted by means of the threaded finger 62 for pre-stressing of the second compression spring in accordance with different weight riders.

Two freely rotating wheels 27 on the transverse axis can have any suitable design that provides the necessary lightness, durability and cheapness. In this case, the diameter is 120 mm and a width of 20 mm, although these dimensions and the profile can be changed according to circumstances.

On a transverse axle set is also provided with a shoulder ring 64, which serves as the attachment for the cable 22, and a return spring 23. The ring 64 is located as close as possible to the middle of the transverse axis 26, to provide a uniform load when lifting and lowering.

Force bias tending to return the support 21 in the off position, create by means of the return spring 23 mounted coaxially on the property, the rack 81, fixed to the top end to the plate 72 and the bearing on a fixed upper ring 82, which forms a support for the upper end of the spring 23, and moving the lower ring 83, which forms a support for the lower end of the spring 23. The lower ring is attached to the hinge connection 84 of the knee-lever mechanism containing two links 85 and 86. The outer end of link 85 pivotally attached to the bracket 87 attached to the TRU is Tina 72 and radiating down. At the lower end of a column-mounted guide tube (not shown) through which the guide wire 22.

The lower end of the bar 1 has a stop (limiting) 89, preventing a complete straightening of the knee-lever mechanism, when the stabilizing device is in its upper position, as shown in Fig. 2, although it becomes almost direct, which provides resistance to inertia forces arising from the movement of the bike on uneven surfaces and tending to force the stabilizer dangle upside-down. Rack 81 has an intermediate stop 90 that defines the bottom, i.e., working, position of the stabilizing device.

The tension cable 22 is attached between the ring 64 and the coil 24, which is installed with the near side of the frame on the shaft 18 of the pedals and bottom bracket or sleeve roller pedals.

The coil 24 is shown in more detail in Fig. 4 and 5. She placed in the outer casing 28, fixed relative to the frame, and comprises a pair of disks 29 coachcourtney element 31 located between the discs 29. Element 31 has a profiled surface 32 which forms the groove 33 of variable depth between the discs 29. The disks 29 fixed to a concentric Central number can be much larger). Inside the ring 34 is a core 36, fixed on the shaft 18 of the pedal and including a series of teeth 37, which may be coupled with the dogs 35.

The outer periphery of the disks 29 are cut-outs 38. Stationary relative to the casing 28 secured a spring-loaded latch 41 located with the possibility of entering into the notch 38. The latch 41 has a release cable 42 leading to the control lever (not shown) that is installed, for example, on the steering wheel. The tension cable 22 is attached to the shaped surface 32 and extends through a hole (not shown) in the casing 28.

When the lead bike in the normal movement through the pedals, backup 21 is in the raised position, as shown in Fig. 2, with telescopic lever 25 is moved apart and the roller 51 is located at some distance from the bus 13. The roller 18 rotates (as shown, in a counterclockwise direction) of the core 36 and the pawl 35 is moved in the teeth 37. In this position, the latch 41 is in the notch 38. Herself coil 24 does not rotate.

When to stop, support 21 is lowered in the position shown in Fig. 1. The wheels 27 are concatenated with the ground, fitted with flanges of the roller 51 engages with the rear wheel 11 and the rear wheel rises from telepathist pedalling ago the roller 18 is rotated, as shown, in the clockwise direction and accordingly rotates the core 36. Dogs 35 mesh with the teeth 37 and the coil 24 is rotated up until the latch 41 will not enter the notch 38. When the cable 22 is forced to gather around the surface 32, resulting in the prop 21 is lowered, overcoming the action of the spring 23. The cable 22 is fixed in the groove 33 of the coil at the point of minimum depth. Profiled surface 32 carry out so that when the winding of the flexible element by rotation of the pedals back depth of the groove 33 is rapidly increasing, which provides increased application of torque to the support 21 through the cable 22 without requiring a corresponding increase in cyclist forces pressing on the pedals. At the critical moment, when the wheels 27 are in contact with earth and perceive the total weight of the cyclist and the bike is lifted from the ground the rear wheel, the depth of the groove 33 and the torque is maximum.

When the support 21 is in a lowered position, the cyclist can stop the bike without removing your feet from the pedals and without losing balance. The support 21 is held in lowered position by enabling the latch 41.

When the cyclist wants protoliths 42. When this latch out of the notch 38, and the spring 23 raises the support 21. As a result of this tension wire 22 leaves the shaped surface 32, rotating the spool 24 in a counterclockwise direction until such time as the latch 41 is again fixed in the cutout 38. This again provides the holding struts 21 in the raised position.

When the prop is in the working position, the grip of the tires between the flanges 52 of the roller 51 provides reliable transfer of most of the mass of the rider through the rear wheel 11, the roller 51, a transverse axle 26 and the wheel 27 to the ground, and the flanges 52 also provide a transfer between the axis 26 and the rear wheel 11 of the lateral loads due to a small tilt of the bike or the roughness of the surface of the earth. Thus, a rectangular supporting structure formed by the rear wheel 11, the spindle, the lever 25 and the transverse axis 26, it will be very hard, and the lever 25 will not be exposed to excessive voltage, even when tilted.

In Fig. 6 shows a modified construction similar to that shown in Fig. 1 -5. In a modified design of a flexible link 22lpasses from the coil 24 through a tube (not shown), which is attached to the Bicycle frame at the front end of the supports 15 CE is the AMA bike, opposite to that on which the coil 24, i.e. on the other side of the frame, where the drive chain. Flexible link 22lpasses backward and downward from the rear end of the tube below the lower branch of the drive chain from the rear wheel 11, the opposite arm, and attached to the transverse axis 26 through the ring 64 from the roller 51, the opposite fork 57, through which the transverse axis 26 is attached to the lever.

When the stabilizing device is in a lowered position, enclosed load (weight) is seeking to move the transverse axis 26 ago, because the geometric axis transverse to the axis 26 is located behind a vertical line passing through the geometric axis of the sleeve 12 rear wheels. Therefore, when the latch 41 is in the notch 38 on the disks 29 of the coil 24, the flexible link 22lis under tension, which prevents the movement of the transverse axis in the backward direction and at least partially releases the plug 57 and the lever 25 is generated when this torsional moment about the longitudinal axis of the lever 25. Modified design, therefore, is more rigid and stable when you stop the bike.

Although in the described modificirovana circuit, and provided the tube to allow translation of the flexible link 22lon one side of the bike to another, it may be possible to position the coil on the same side as the sprocket chain.
