belonging type of bicycles that are now in use everywhere are both pedaling and steering the bike using a single front wheel and pair of Rear wheels caused, whereby the latter, rigid and always running parallel, are rotatably mounted «Although this kind of Bicycles in general works satisfactorily, it has a number of disadvantages.

One of these disadvantages lies in the fact that the horizontally rotatable arrangement of the front wheel, for the purpose of Control of the bicycle, poorly brought into harmony with the stepping of the pedals for the purpose of locomotion of the bicycle because you have to turn the front wheel at a sharp angle when you end your bike want.

Another disadvantage can be seen in the fact that the handlebar attached to the front wheel can be turned into one for quick steering unsuitable position must be rotated when turning the front wheel to make a turn or around the Corner to fahran.

Another disadvantage lies in the fact that such bicycles belonging to the prior art have an elevated position Have center of gravity, making it difficult to guide and steer such bicycles while turning.

■■ π

In an effort to obviate some of the foregoing disadvantages, other types of prior art are used Technology belonging bicycles equipped with three wheels, of which the front wheel is only used for the pedal drive and you control the bike by turning the rear wheels. Although such a measure is in has generally proven satisfactory in an effort to avoid some of the aforementioned disadvantages by such an arrangement, the disadvantage has been brought about that it is difficult once a turn is started has to move the means for steering the bicycle back into a central position in which the bicycle is on a straight-ahead course can control

In view of the above-mentioned facts and circumstances, which for the prior art belonging vehicles for playing o. The like. Are characteristic, it is the main aim of the present innovation, a novel And to create advanced game vehicle o. The like. That avoids the disadvantages listed above and with controllable Rear wheels, a means for controlling the rear wheels and another means is equipped by which the means for controlling the rear wheels pre-influencing to take a middle position.

Another aim of the present innovation is to create a vehicle of the type described that has a

-I ₁ -

Imitates aircraft that is leaning into the curve and turning maneuvers performs.

Another aim is to create a three-wheeled bicycle in which the front wheel is only used for propulsion is used by means of pedals and the control of the bicycle by a horizontal rotation of the rear wheels in one happens in such a way that the bicycle leans into the curve during a turning maneuver.

Another aim of the present innovation is to create a bicycle from the one equipped with three wheels Kind of seeing in which the front wheel is only used for propulsion by means of pedals, while the controls are operated by the horizontal twisting of the rear wheels happens, whereby the Front wheel communicates with the mechanism of control in such a way that the front wheel is in the Sets the direction of the turn to be performed.

Furthermore, it is an object of the present invention to provide a vehicle of the type described above, which is equipped with steerable rear wheels, which are operated by a link mechanism in such a way that during a turn the wheel of the inside the turn by about 55 degrees, and the wheel on the outside is only adjusted by an angle of kO degrees.

Furthermore, it is an aim of the present innovation to create a vehicle of the type described above, which has such a structure that the center of gravity of the vehicle user shifts upwards when the means to control the vehicle from its middle position - moved so that the means for controlling the vehicle receives a pre-influence on the body weight of the driver, in to return to the middle position.

Another aim of the present innovation is to improve the driver's seat of a vehicle of the type described above to be arranged on a three-dimensional curve, which with a curve-following arrangement during the rotation by the control- Mechanism of the vehicle cooperates in such a way that the driver's seat of the vehicle is raised when see the Control mechanism moved out of the central position, so that the center of gravity of the driver of such a vehicle is also shifted upwards and consequently the control mechanism a pre-influencing gets into the middle position move back.

Yet another aim of the present innovation is to be seen in a bicycle equipped with three wheels create which has steerable rear wheels and has a pedal driven front wheel that rotates in the direction of the taken turn as a result of the control process obliquely, whereby the rear wheels are forced to the

Path to follow the compound pivoting movement.

According to a first embodiment of the present The innovation is a vehicle for playing or the like in the form of a three-wheeled bicycle with controllable rear wheels and one created by pedal driven front wheel, which in such a way connected with a steering control means stand that the front wheel is forced to lie down in the direction of the taken turn when turning movements, but is prevented from a horizontal twist itself.

The vehicle has a front wheel fork, which the front wheel driven by the pedals. This fork has a non-rotatable, in a first tubular shape Member attached tenons, with the tubular member in turn sits rigidly in a tubular rear-wheel axle, so that a tube frame in the shape of a T results.

A second tubular member is rotatably attached to the first tubular member and is operated by a steering control lever rotatably move, the latter being rigidly provided at the front end of the second tubular member is ο a support arm extending from the underside of the rear End of the second tubular member and causes the control of the rear wheels by a connecting rod and a composite link mechanism, which the rear wheels

of the vehicle connects to the rear wheel axle.

During the control processes, the link mechanism causes that one rear wheel moves forward and upward, and the other rear wheel moves backward and downward adjusts. This not only causes the rear wheel axle to be tilted and the vehicle to move puts in the curve, but it also shifts the center of gravity of the driver of such a vehicle upwards, which in turn the control mechanism has a pre-influencing effect on ingestion a middle position. As the front wheel fork is rigidly connected to the rear wheel axle, results from the inclined position of the rear wheel axis also an inclined position of the front wheel in the direction of the turned one Turn. In addition, the inclined position of the rear wheel axle ensures that the driver's seat is also inclined since it is rigidly connected to the first tubular member. The pre-influence acting on the control mechanism to take the middle position is to be regarded as a novel and progressive invention feature, there the weight of a child using the vehicle required to return the steering mechanism to the center position after a turn to be performed, the force required is reduced to a minimum.

According to a second embodiment of the present The innovation is a vehicle to play with ο "the like. in the form of a created a three-wheeled bicycle with a front wheel fork,

which carries a front wheel driven by pedals, the front wheel fork is rigidly connected to a frame member in such a way that the front wheel is not in the horizontal plane lets turn. The rear wheels can be rotated on an axle link stored, which can be pivoted to the vehicle frame by a inclined bolt is connected in such a way that when turning with the vehicle by pivoting the rear-wheel-axis this axis is inclined. the The vehicle seat has a curve-following arrangement that is associated with a Curve interacts ο The curve is in on the rear wheel axle arranged in such a way that the curve describes an arcuate path when the rear-wheel axle through a, with a pivotable control lever connected, link system is pivoted around. The curve-following arrangement has such a shape, that the curve lifts the vehicle seat when the control lever is off its middle position is pivoted out. Raising the seat becomes the center of gravity of the driver of such a vehicle shifted upwards and as a result the control lever receives a pre-influence to take a central position.

A third embodiment corresponds to the present innovation the first embodiment with the exception that the tubular links have been replaced by a one-piece stamped metal construction.

The features of the present innovation, which are to be regarded as novel and progressive, are described in detail

disclosed in the subordinate claims "The present innovation is both in its structure and in its mode of operation, together with their further aims and advantages, best by referring to the following description and the accompanying ones Drawings where the same reference numerals are used indicate the same items in the different views.

With renewed reference to the drawings, reference is made in particular to FIGS. 1 to 5, in which a vehicle for playing or the like in a first embodiment of the present Innovation is shown, wherein the vehicle is generally designated 10 and a vehicle chassis and a vehicle body 14. The chassis 12 has a front wheel assembly 16 and a rear wheel assembly 18 and a steering mechanism 20. The front wheel assembly 16 includes a pedal driven wheel 22 that is rotatable is mounted between the arms 24 of a front wheel fork assembly 26 on a pedal crank assembly 28. Through the pedal crank assembly 28, the vehicle 10 is propelled by a rotating movement of the front wheel 22 by the, to the opposite sides of the vehicle 10, crank arms 30 and 32 by means of the rotatably mounted pedals 3 ^ and 36 actuated.

The front wheel fork assembly 26 has a stem member 38 that is non-rotatable in a first tubular member 40 is fastened by bolts 42. The bolts 42 transmit a Torque from the first tubular member 40 on the front wheel fork assembly 26. One end 44 of the member 40 is forked, so that it surrounds a rear axle assembly 46 in a spreading manner,

which is part of the rear wheel assembly 18. The end 44 is rigidly connected to the rear axle 46 by a weld 48, so that every inclined position of the axle 46 generates a torque on the tubular member 40 transfers. It should be noted that the fork assembly 26 has a horizontal position, in contrast the fork position on some prior art vehicles of this type where the front wheel fork Assembly is arranged vertically. In addition, it should be noted that the shaft 38 is the horizontal main axis line of the chassis 12 forms.

The vehicle body 14 is rigidly attached to the first tubular member 40 by a suitable support bracket 50, which includes the member 40 tensioning, and is there chrch the bolts 52 held firmly and securely. The body 14 has a tub-like seat 52 with a floor seat surface 54, which through Bolt 56 is attached to the support bracket 50. The seat 52 has a back support 58, which by two, at an angle to each other, Links 60 and 62 is formed and which have lower edge pieces 64 and 66, respectively, on which the arm supports 68 and 70, respectively are attached. The seat surface 54 of the seat 52 protrudes backwards on the back support 58 and forms the bracing for an aircraft tail rudder imitated assembly 74, the consists of a vertical member 76 and further members 78 arranged essentially horizontally. The links 78 protrude laterally beyond the wheels 80 and 81 of the rear wheel assembly 18 to protect the driver of the vehicle 10 from dirt

or the like which may be whirled up by the wheels 80 and 81. The vehicle body assembly 14 has also a seat belt 82 interposed with seat 52 the lower edges 84 of the arm supports 68 and 70 and the Floor — seat 54 can be attached therethrough.

The control mechanism 20 includes a second tubular member 86 which the first tubular member 40 alongside between the bolts 42 and the support bracket 50 in such a manner that the second tubular member 86 rests on the first tubular member 40 without substantial linear displacement, along the main axis of the chassis 12 can rotate. Said second member 86 can by a Driver of the vehicle 10 can be rotated by means of a lever 88 which is rigidly connected to the link 86 by a suitable weld 90 connected is. The control mechanism 20 also has an associated rod 92, one end 94 of which is rigid by a weld 96 to the second tubular member 86, and the other end 98 thereof rigidly with a triangular plate 100 connected is. The triangular plate 100 has a pair of openings 102 into which the hooked ends 104 of a pair from connecting rods IO6 and 108 are hung through the the steering mechanism 20 is in communication with the rear wheel assembly 18.

The rear wheel assembly 18 has a first inclined kingpin housing 110 which at one end

attached to the axis 46 and a second, inclined Aehsschenkelbolzen-Housing 114, the one at the other end 116 of the axle 46 is attached. It also has the rear wheels assembly 18 shows a first kingpin assembly 118 rotatably supported in the first housing 110 at the upper end thereof a plate 120 sits. A second kingpin assembly 124 is rotatably supported in the second housing 114, the one second plate 126 which is attached to the upper end 128 of said housing «The lower ends I30 of the King pins 118 and 124 are welded 132 rigidly connected to the essentially U-shaped arms 134 or I36, as shown for kingpin 124 in FIG. One end 138 of each of the arms 134 and 136, respectively, faces a suitable axle spindle, as can be seen at number 140 in FIG. 2 for arm I36, with the axle spindles the wheels 80 and 81 are rotatably mounted. A first stiffening strut 142 is at one end 144 through a bolt attached to the end 138 of the arm 134 and at the other end 148 to the plate 120 by a bolt 150. A second strut 152 is at its first end 154 by a bolt 156 with the End I38 of arm I36 and with the other end 158 through one Bolt I60 is firmly connected to the plate 126. Each of the two plates 120 and 126 has a cut-out sector 162, the two, spaced from each other stop members 164 and 166 forms, on which one, with the aforementioned Stop members interacting stop I68 finds its limit, which in turn sits on the axis 46.

The other ends 170 of arms 134 and I36 are apertured 172, in which the L-shaped ends 174 of the connecting rods 108 and 106 are hooked to the control mechanism 20 to be connected to the rear wheel assembly 18, thus forming a composite link system in the manner described above is generally identified here by the reference number I76 is"

The vehicle 10 leans into the curve during a turn in such a way that the rear-wheel axle 46 inclined, as shown in Figure 4 for a left turn. This causes the front wheel 22 to be in Set the direction of the turn, as can also be seen from FIG. The axis 46 is forced to move about 10 to set obliquely to the horizontal, through the arrangement of the composite link system 176, through which the one the rear wheel is moved forwards and upwards, and the other rear wheel is moved backwards and downwards. Through this the center of gravity of a driver of the vehicle is in turn shifted upwards by about 1/4 - 5/16 inches (= 6.35 - 7.9 ^ m / m), thereby pre-influencing the control mechanism 20 to assume a neutral or center position in which the vehicle is steers straight ahead. This result is achieved in part by removing the two kingpin housings 110 and 114 are connected to axle 46 in such a manner that the major axes A-A of kingpin 118 and 124 form an angle of about 19 in two planes (i.e. if one uses the axis-central

Lines from backwards and viewed from one side) with a vertical line B-B, which through the lower ends I30 the kingpin goes. This inclination of the kingpin 118 and 124 in connection with the U-shaped version of the arms 134 and I36 force the inner, lying in the curve, Rear wheel swivels in by about 55, while the rear wheel on the outside only swivels about 40 in the course of the Run around a corner. For example, wheel 81 turns about 55 degrees while wheel 80 turns about 40 degrees Degrees when the vehicle 10 is turning left performs, as shown in FIG. In addition, the wheel 81 lies at about 2 degrees in the direction of the turn while this is the case with the wheel 80 with approximately 7 degrees. The end II6 the axle 46 slopes downwards, while its end 112 is raised during a left turn. This will make the tubular Link 40 and shaft 38 for counterclockwise rotation caused, as Figure 4 shows, which in turn the front wheel 22 assumes an oblique position and itself inward in the direction of the turn at about 10 degrees, compared to the position shown in Figure 4. Because the vehicle body 14 is rigidly connected to the tubular member 40, he takes the, in Figure 4 approximately shown oblique position due to the Rotation of tubular member 40 a. Therefore, the vehicle 10 not only leans into the curve during a turn, but rather it also leans in the direction of the turn taken, which greatly reduces the possibility of vehicle 10 is out of the curve due to the centrifugal force

to be worn. The driver's center of gravity in the seat is shifted upwards, as can be seen in FIG.

Reference is now made to FIGS. 6 to 9, in which a vehicle for games or the like according to a second embodiment of the present innovation is generally designated by 210 that includes a chassis 212 and a vehicle body assembly 214. The chassis 212 has a front wheel assembly 216, a rear wheel assembly 218, and a steering mechanism 22Oo The chassis 212 also has a frame member 240, which at its front end with fixed, parallel spaced apart side walls 242 and a cover wall 244 is provided, which extends through a Inclined section 248 combined with a rear wall 245. The fixed walls 242 extend from the front of the Vehicle seat backwards and downwards towards the rear wall of the frame 240, which also has a floor wall 250.

The front wheel assembly 216 includes a pedal powered wheel 222 that is pedaled by a pedal Crank shaft 228 is set in motion and is rotatably supported between arms 224 of a front wheel fork assembly 226. The crank shaft 228 has two opposing crank arms 230 and 232, each with a pedal 234 and 236, which are attached to the named arms are rotatably mounted. The front wheel fork assembly 226 is attached to the frame by suitable bolts 251 connected, each of said bolts being one of the arms

- hostile 19 each with an upstanding on the frame 240, the fixed flange

The rear wheel assembly 218 sits a rear axle 246, at the ends of which the wheels 280 and 281 are rotatably mounted, where the above-mentioned rear axle is firmly in contact with the frame 240 by means of a pivot pin 276. The top piece this bearing pin goes through a bushing 278 and through the inclined Afeschnitt 248 of the cover wall 244 and is in held in its position by a suitable position securing means 280. The lower piece of the bearing pin 276 goes through the Axis 246 and through a control Hefeel 282, which is fixed is connected to the axis 246. By a suitable nut 284, which is screwed onto the threaded lower end of the bearing pin 276 and against the control Hefeel 282 the axis 246 is prevented from moving away from the bearing— pin 276 to loosen. The Steuer-Hefeel 282 has a saddle piece 286 extending backward and upward from axis 246 ·? · A cam roller 288 is on pin 290 rotatably mounted within said saddle, whereof said pin with its ends in the holes 292 of the saddle 286 fezwv of the axis 246 is at rest. The cam roller 288 protrudes through an opening 294 of the saddle 286 and lies against a fixed curve 300, which is fixed rigidly on the bottom wall 250 of the frame 240. Usually the role is 288 in a deeply deformed Afeschnitt 302 of the curve 300, but can be with the axis 246 feei its rotation about the pin 276 Freewegen freely, so that the cam roller 288 on one of the elevated

Sections 304 converge on each side of the recessed curved Section 302 are provided. This creates the framework 240 raised and due to the inclined position of the bearing pin 276 inclined at the same time.

The control lever 282 forms part of the control mechanism 220 and has a bush 3O6 in which a control joint 3O8 is performed. This joint piece 3O8 is 3IO at one end of the control control lever 312 attached, which in turn also forms part of the control mechanism 220. The joystick 312 is rotatable on frame 240 by means of a sleeve 314 and is pivotable from a vertical or central position in a first direction in which the vehicle a left turn, or in a second direction in which the vehicle executes a right turn. The pivoting of the control lever 312 causes the axis 246 to rotate around the Pin 276 rotates and cam roller 288 onto one of the sections 304 runs up, whereby the frame 240 is raised. At the same time, the skew angle of the pin 276 becomes the axis 246 itself causes a corresponding inclination. Since the front wheel fork assembly 226 is rigidly connected to the frame 240 causes the inclination of said frame occurring in the manner described above that the front wheel 222 lies in the direction of the pivoting of the vehicle to be carried out, as shown in FIG. Raising the frame 240 shifts the center of gravity of the driver of the vehicle upwards. This gives the control lever 312 a pre-influencing

flow to return to a vertical or central position, reducing the force required to a minimum, steer the vehicle 210 straight again.

The vehicle body 214 has a front wheel guard 306, which acts as a mud flap for the front wheel 222. In addition, the body 214 has a seat 252, which is shown in FIG is rigidly connected to the frame 240 in such a way that the seat, together with said frame, during implementation a turn of the vehicle is raised and assumes an inclined position. This creates the pretense of one aircraft turning when the front wheel 222 and seat 252 pivot in the direction of the turn to be performed.

The embodiment shown in Figures 10 to 18 The present innovation, generally designated 410, is a modification of the configuration shown in FIGS. leadership example. The vehicle 410 is for a child from an average of 3 to 7 years and shows something different structural means on. Therefore, the vehicle is also suitable for a child who is 8 years old on average. The center of gravity of the vehicle 410 and of a driver seated on it is opposite to that in the embodiment according to FIGS Figures 1 through 5 present proportions by about an inch (= 25.4 ni / m) lower. The 10 degrees for swiveling the Front wheel 222 in the direction of the turn to be performed

Vehicle have been retained, as a child * Experimental program has found that a child can handle the vehicle 410 better at a 10-degree slope than at 8 to 12 degrees, although such an order of magnitude is also a satisfactory result when turning into a curve would bring. The wheel plane in the vehicle 410 is selected so that a greater proportion of the weight of the driver of one such a vehicle is shifted more to the front wheel than to the rear wheels. The driving child is therefore preferably seated closer to the front wheel. The vehicle 410 is also constructed in such a way that an older child can incline an II degree can take without running the risk of the vehicle 410 rearing backwards.

The vehicle 410 has a chassis 412 and a body 414. The chassis 412 has a front wheel assembly 416, a rear wheel assembly 418 and a steering mechanism 420 on. The front wheel assembly 416 has a pedal driven wheel 422 that is rotatable between the arms 424 a front wheel fork assembly 426 on a pedal crank assembly 428 is stored. As a result of this pedal-crank arrangement, the vehicle 410 is driven by a rotating movement of the front wheel 422 is moved as soon as the crank arms 430 and 432 arranged on the opposite sides of the vehicle are actuated by the device of the pedals 434 and 436 rotatably mounted thereon will.

It will be apparent to one of ordinary skill in the art It seems obvious that the vehicle will be made of a number of different materials by way of a number may be manufactured by different manufacturing processes, although the vehicle shown here for the purpose of illustration, but not of limitation, is mainly made up Sheet metal — material is made and made by a suitable metal stamping technique has been made. This is where the front wheel fork is Assembly 246 is molded from a single piece of metal along with a sub-frame 440. With such an arrangement it follows that each inclined position of the frame 440 opposite the horizontal plane a corresponding oblique position of the front wheel 422 out of the vertical plane. The frame 440 has a cover wall 442 with a first raised one Section 444 which has a seat receiving surface area and a second raised section 446 which has a seat guide forms. The first raised portion 444 has a plurality of aligning holes 448 for adjustment of a seat, such as will be described later, which can be arranged in such a manner that a driver of the vehicle 410 in consideration the arrangement of the pedals 434 and 436 has a correct sitting position. The frame 440 also has a pair of fixed side walls 450 and an end wall 452 and receives a particular stability and strength through inwardly shaped flanges 454 at the lower ends of the side walls 450 and the End wall 452. A plate 455 can also be attached to the flanges 454 by screws 455a to the frame 440

to give additional reinforcement. The end wall 452 serves as means for receiving the rear axle and slopes downward and inward towards the front wheel 422 and 422 forms an angle of 19 degrees with a vertical line. The wall of the axle 452 has a first one pointing laterally outward End 456 and a second laterally outwardly facing end 458, with a cylindrical kingpin receiving sleeve 460 (FIG. 12) attached to each of said ends is. The sleeves 460 run diagonally downwards at approx. 19 degrees to the vertical and diagonally downwards at approx. 19 degrees inward toward front wheel 422.

The vehicle body 414 is provided with a tub-like seat 462 and a front wheel mud flap assembly 464. The mud flap assembly 464 has a top wall 466 and fixed side and back walls 468 and 470, respectively into an opening 472 provided in the top wall 440 fit in. The lower ends 474 of the side walls 468 are each provided with an outwardly facing flange 476, by means of which the Sehmutzfänger 464 is rigidly connected to a respective flange 454 of the side walls 450 (FIG. 16) provided for this purpose is. The seat 462 has a bottom wall 478, of which the fixed suitable bolts 480 (Figure 12) for the adjustable Attachment of the seat 462 to the deck wall 440 protrude and pass through matching holes 448. The seat 462 can can therefore be secured in the correct position on the deck wall 440 by turning the threaded bolts 480

Secured by wing nuts 482. The seat 462 also has a suitable back support 484 and outwardly protruding Members 486 and 488 which act as mud flaps over the rear wheel assembly 418 and also has one with seat belt 489 firmly anchored to the seat (Figure IO).

The rear wheel assembly 418 includes a first kingpin 490 which passes through a sleeve 460 and a first wheel axle carrier 492 with the end 456 of the Axis 452 pivotally connects »This assembly also contains 4i8 a second kingpin 494 which, through the sleeve 460 assigned to it, forms a second wheel axle carrier pivotally connects to end 458 of axle 452. The axle carriers 492 and 496 can be suitably stamped from a Sheet metal construction can be produced, with each axle beam having an end 500 and within the frame an outside end 498 has "Each of the outside ends 498 has an axis 502 on which a rear wheel 504 is rotatably mounted (Figure 11). The axes 502 are on a slightly lower level than the end wall 452, so that the axle supports 492 and 496 obliquely inwards upwards, from their ends 498 lying outside the frame their inner ends 500 to rise. The ends are forked and have an upper arm 506 and a lower arm Arm 508, each of which has an opening 510, through which a corresponding kingpin passes through. The lower arms 508 have control arms 512 located in the

same plane, substantially perpendicular to the former, and with openings 514 at their free ends 516 are provided.

The control mechanism 420 mimics the control device of an aircraft and consists of the control stick 518 an upper end 520 and a lower end 522. The upper end 520 has a handle 524, while the lower end 522 through an elongated opening provided in the top wall 440 protrudes and then engages in a pocket 528 which is attached to the Control rod 530 is provided. The control rod 530 can preferably be made of a metal sheet, the rod being given approximately the cross-section shown in Figure 17, however, at its front and rear ends, the substantially sections 532 and 53 ^ respectively. The control rod 530 is in Vehicle 410 by storing end 532 in a trestle rotatably arranged, said bracket sitting firmly on the deck wall 440 and protruding downwards, while the other end 534 of the control rod 530 is rotatably mounted in another bracket 538 which is firmly attached to the rear wall 452. The rear end 53 ^ of the control rod 530 has a fixed Bracket 540, which has a pair of openings 542,

The steering mechanism 420 is with the rear wheels assembly 418 is coupled by a pair of control links 544, each of these links 544 having a first hook end 546 has which in one of the openings 542 of the bracket 540

engages, and has a second hook end 546 which engages in an opening 5-L4 of a control arm 5 * 6. The length of a each link 544 is such that in accordance with the geometric arrangement of the axle carriers 492 and 496 die Rear wheels 504 are properly adjusted once and for all. When the control stick 518 is pivoted to the left as far as possible As FIG. 11 shows, the axle support 496 pivots rear right wheel 504 about 50 1/2 degrees backward and the axle beam 492 moves the left rear wheel 504 by about 56 degrees forward into those positions which can be seen in FIG. 14 in dashed lines. At the same time pose themselves frame 440, seat 462, and front wheel 422 along with the outboard end of seat 462 inclined at about 10 degrees upwards, while the inner end of said seat tilts downwards at an angle of about 10 degrees. As a result, goes the vehicle 410 at an incline of about 10 degrees opposite the horizontal in the chosen curve, so that a driver with a deviation of about 10 degrees to that caused by his center of gravity running center line comes to rest. This increases the driver's center of gravity by approximately 1/4 to 5/16 inches (= 6.35 to 7.94 m / m) is shifted upwards, as can be seen in the diagram in FIG. 19, whereby it can also be seen here that With some of the prior art bicycles, the rider's center of gravity increases by approximately 1/4 to 5/16 inches (= 6.35 to 7.94 m / m) shifted downwards. When the rear wheels 504 are in the position shown in FIG. 14 in a dashed line are swiveled in, the vehicle 410 is capable of a

To perform a left turn in which a line passing through the axes of the wheels 422 and 504 is in a common Point 550 hits, with that on the neck bearer 492 attached, internal wheel 504 is 3 degrees from the vehicle 410 outwards, and the outer wheel 504, which is mounted on the axle support, moves 15 degrees inwards leans towards the vehicle.

It is naturally evident that the control stick 5I8, as shown in FIG. 11, can be pivoted to the right in order to carry out a right turn, so that the elements shown in FIG. 14 in a dashed line drawn positions of the wheels 422 and 504 must be seen in the opposite direction.

During the turns, one rear wheel moves forwards and upwards and the other rear wheel moves backwards and down to incline the vehicle 410 and shift the driver's center of gravity up. Both features of the invention are due to the oblique Arrangement of the kingpin caused, which in the above-described embodiment of the present innovation come into use.

While the vehicles shown in detail here are suitable for games or the like in their entirety, the objectives are more detailed To achieve innovation and the aforementioned advantages, it is taken for granted that all

Details only serve to explain the presently preferred embodiments of the present innovation and that no other restrictions on the details of the structural designs or innovations shown here moderate designs are intended as those which are reflected by the ideas disclosed in the underlying claims result-?
