In this specification, one or more wheels are meant to include one or more casters or wheels as casters. BACKGROUND OF THE INVENTION Many vehicles (as defined above) have a majority of wheels (as defined above). 'The wheel train is independently mounted on the axle of the vehicle, such that the wheel can rotate against the axle to move the vehicle, where Including around the corner. In many cases, the wheel train operates independently. Good examples include work carts and shopping carts. In many cases, when the axle or wheel is knocked or slightly damaged, it makes the vehicle difficult to use, or it may make a certain Wheel deflection thus creates braking when the vehicle is moving "and when the vehicle crosses a slope, especially a lateral slope, the vehicle is easy to adapt to the slope 'There are already many loads of structure carts rolling down the parking lot slope or driveway. . These vehicles are often difficult to overcome in small corners, especially when the space is too small. This is due to the independence of the wheels. Before the wheels can correctly advance, they must be slightly moved to have proper rotation. ) (210X29 ^?

Most of the following wheels (as defined above) are carriers (as defined above), each wheel is attached to the vehicle using an axle. 'Each axle has a longitudinal axis and each wheel has a separate axle; the The arrangement is such that the rotation of the wheel shaft along its longitudinal axis causes the wheel mounted there to redirect the vehicle. Each wheel shaft is attached with a follower device. Each follower device can be driven by a drive device to rotate a wheel shaft. Causes other wheel axles to also rotate their longitudinal axis. The driven device is preferably a gear 'the driving device is preferably As a gear system, the driving device can also be a chain or belt drive. In a favorable situation, a spring tensioning device is provided to maintain proper contact between the driving device and the gears, and it is better to provide a centralized device. When the driving device is a gear system, the gear system preferably includes a central gear that engages the two gears, and uses the intermediate gear to engage other gears. * The two gears that are in direct contact with the central gear are preferably located on one end of the vehicle. Other gears use an intermediate gear to cause their axles to rotate in reverse with those gears that directly contact the central gear. The wheels are preferably a front wheel pair and a rear wheel pair, and the gear train of the front wheel pair is directly engaged with the central gear. In addition, the front wheel pair can be driven by a chain or belt drive, so the rotation of one of the front wheel pairs will cause the other to turn in the same direction, and the other wheels will rotate in the opposite direction.

For a description of the more detailed embodiment, please refer to the embodiment of FIG. 1, which shows a carrier generally indicated by 〖0, which has an integrated body 12, which is subject to a Pushed or driven by a negative street on a handle (not shown) or a vehicle. The imagination 12 has four wheels 16 which are substantially the same or different. The wheels 16 are arranged into a front wheel 16 pair 18 and a rear wheel 16 pair 20. Each wheel 16 is mounted to the body 12 of the carrier 10 by a wheel axle 22, each The axles are all separated. Each wheel 16 is attached to its axle 22 using a mounting bracket 24, so the wheels 16 are used as casters. A gear 26 is fixedly mounted to each wheel shaft 22, and the gear% is preferably installed in the body 2 although it may be above or below Zhao 12. Each gear% does not directly engage any other gear 26. Each gear 26 is preferably a complete 360 degree gear, so the axle 22 can be rotated 360 degrees so that each wheel 16 can advance in any direction. A central gear 28 is also mounted in the body 12 using a wheel shaft 30 ', and the gear 28 can be positioned inside, above or below the desired 12, the central gear 2s directly ..

Description of the invention (4) Gears 26 that engage the front wheel 16 to 18 »Therefore, the rotation of the axle 22 of at least one of the front wheels 16 to 18 will cause the relevant gear 2.6 to rotate with the axle 22, And the center gear 28 rotates, so the other wheel 16 of the front wheel 16 to 18 and its other gear 26 will also rotate. By this arrangement, the two front gears 26 will have the same steering, so each wheel 16 of the front wheel 16 to 18 Will point in the same direction, if the two front disk wheels 26 are approximately the same, the wheels 16 of the front pair 18 will all point in the same direction at the same angle. For the rear wheels 16 of 20, the gear 26 is engaged with the center gear 28 by the intermediate gear 32 And is rotatably mounted in, on or above the body 12 by the axle 34. Therefore, the rotation of the central gear 28 will make the intermediate gear 3 2 turns and will rotate the gear 26 of the rear wheel 16 to 20 and the gear 26 of the front wheel 16 to 18 in the opposite direction. Therefore, 'when the central gear 28 rotates, the gear 26 of the rear wheel 16 to 20 will rotate with the The gears 20 of the front wheels 16 to 18 rotate in the reverse direction. In this way, the rear wheels 16 to 20 will move together in the reverse direction of the front wheels 16 to 18. Therefore, if the front wheels 16 to 18 turn left, the rear wheels 16 to 18 Turn 20 to the right. The gears 26 are preferably the same, so that the angles of the front wheels 6 to 18 and the rear wheels 16 to 20 are the same, and the rotation ranges are the same. The gear 32 may be different from the gear 26, but they should be the same as each other. In this way, when the force applied to the handle is to the left, the front wheels 16 to 18 will turn to the left 'and the rear wheels 16 to 20 will turn to the right, which makes the body 2 easy to turn-this direction is often along the center (vertical) The axis 26. Although the gear 26 may be a circle, if necessary, it is preferably 36 °. The central gear 28 may also be multi-segmental, or a complete 360 ° tooth. __ -7- From the application @@ 家 样 准 （CNS) (21GX297 mm) ------ I ----------- • installation ------ order ------ ice (Please read the note ^ 'on the back before filling (窎 Page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, A7 B7 42162q V.

Therefore, there are four wheel steering, please also Note that it can also have the traditional Qing wheel movement ', in which the wheel 16 can rotate 360 degrees, but because it was originally connected by the wheel system, it is impossible for any wheel 16 to bump. Therefore, there can be a wheel 16 'with a larger diameter, and because the wheel 16 is directly aligned with the positive Angstrom,' the center of gravity will always be between the wheel 16 ', and there is a sufficient distance between the center of gravity and the wheels 16 to have a certain degree of stability' This is true even for smaller bodies 12. And by calibrating the wheel 16, it is difficult to move the body 12 in the lateral direction of the wheel 16. Therefore, if the wheel 16 is calibrated in the direction of a front wheel (as shown in the figure), it is difficult to move the body 12 sideways, which is very different from a normal caster. One side force will turn the caster on at least one end, so that the caster will Cooperating objects move.

The central gear us directly engages the two gears 126 of the front wheel 116 to 118. The movement will cause the wheel shaft 122 to rotate, thus rotating the related gear 126, which will cause the central gear 128 to rotate. Therefore, the other gear 126 of the other wheel 116 of the front pair 11S will also rotate. Using this arrangement, the two front gears The rotation of 126 will be in the same direction, and the front wheels 116 and 118 of each wheel Π6 will point in the same direction. 'If the two front wheels 126 are approximately the same, the front pair π 8 wheel 116 will point in the same direction at the same angle. For the rear wheels 116 to 120, the gear 126 is connected to the central gear 128 with the intermediate gear 132, and is also rotatable using the axle 124 It is mounted in, on, or above the body 112. Therefore, the rotation of the central gear 128 will rotate the intermediate gear 132 'and this will make the gear 126 of the rear wheel 116 to 120 and the gear 126 of the front wheel 116 to 118 into Reverse rotation, so when the central gear 128 rotates, the gears 126 on the rear wheels 116 to 120 will rotate in reverse with the gears 126 on the front wheels 116 to 118. In this way, the rear wheels 116 to 120 will be on the front wheels Π6 to 118 It moves together in the reverse direction, so if the front wheels 116 to 118 turn left, the rear wheels 116 to 120 turn right. The gear 126 is preferably the same, so that the angular rotation range of the front wheels 116 to 118 and the rear wheels 116 to 120 are the same. However, the gear 126 of the rear wheel ^^ pair 120 and the gear 126 of the front wheel 116 pair 118 are preferably different.

Limitation, because the wheel 116 is located beside the body 2], it is easy to contact the body 120 with a large angular movement of the wheel 116. Therefore, the gears 126, 132, and 128 can be segmented gears. In this case, the gears 128 have two or four segments', which is sufficient to allow the wheels 1 to 6 to have the maximum amount of movement to the ship 112. It is preferable to provide a centralized device 136, which may be incorporated herein by reference in accordance with my earlier patent application number PP0590 '. In addition, it is possible that the general unit 137 'has a projection 139 on the central gear 128 in the unit. The rotation of the central gear 128 causes the projection to contact the cymbal device 137, thereby causing it to move around the mounting portion. A spring 141 is provided to deflect the cymbal device 137, and thus the projection 139 and the central gear 128 are brought to the center position as shown. The working method of the embodiment of Fig. 4 is very similar to that of the embodiment of Fig. 1. Similar components of the embodiment of the fourth circle are similarly numbered, but the number 2 is added in front. The vehicle indicated generally as 210 has a bell 212, four wheels 216 arranged as a front wheel pair 21 8 and a rear wheel pair 220, as in the embodiment of FIG. In this example, the body 212 is almost the same as the one used in supermarket carts and can be stacked, so the wheel 216 is a _ wheel, although it can be known from the above that any form of wheel * can be used, and each wheel 216 is mounted on a wheel shaft 222. The gear 226 is mounted to the wheel shaft 222. The gears 226 are preferably the same and have a fixed degree of angular change. A continuous chain or transmission belt 238 is operatively connected to these gears 226. If a transmission belt 238 is used, it is a toothed belt on both sides. Although two pieces are shown, preferably at least one idler sprocket 24 is used to maintain the continuity of the chain or belt 238. The idler sprocket 240 is rotatably mounted in the body 212, I-m / 1 I mn I 1- -It I Ding, τ (Please read the notes on the back before filling this page)

Description of the Invention (8) Advantageous situation is: • Provide an elastic yellow tensioning device 242 between the idler sprockets 240 to keep the chain or belt 238 fixed Pulling force, because a chain or belt such as 238 is easy to stretch or change its length depending on the temperature, the spring tensioning device 242 will maintain a fixed contact between the chain or belt 238 with the gear 226. For the first embodiment, a wheel 216 moves to change the direction of the body 212 'will cause its gear 226 to rotate with the axle 222, which will cause the belt or chain 238 to move', thus driving all other gears 226, making all The wheel 216 changes direction, so if, for example, the front wheel 218 moves to the right, the rear wheel 22 will move to the left. This arrangement is most suitable for supermarket carts and the like, because the arrangement allows it to fit into a normal shelf of a supermarket cart without interfering with its stacking performance, stacking with each other and the ability to move in rows. This is due to the rack 212 The interior is generally caused by an open area 244, which is often found in supermarket carts. Although the examples show that the four wheels' can be two or more than any number of related wheels, of course, if a gear is not used, rollers can be used, and there is frictional engagement under the force of impulse. And there may be a combination of belt / chain drive and gear, which is particularly relevant for the rear wheel pairs 20, 120 in the embodiment of Fig. 1, and also for the second and third turns. Alternatively, the idler sprocket 240 in the embodiment of FIG. 4 can be used, and the gear 216 of the rear wheel pair 220 can be operatively engaged with the idler sprocket 240 instead of being driven by a chain or belt 238. The embodiment of Fig. 5 is similar to the earlier embodiment, so similar components have similar numbers, but are preceded by the number 3. The embodiment of Fig. 5 is similar to the embodiments of 2 and 3 (a). -II-This paper is only applicable to the National Standard for Bacteria (CNS Γα4 pits (210X297 mm > < Please read the note on the back before filling in this page).

Invention Description (9) The observation mode shows a carrier 310 with an integrated 312, provided with a '-handle 314 to enable the carrier 310 to move and turn; although not necessary, The body 312 has approximately the same four wheels 316. The wheels 316 are arranged as a front wheel 316 pair 318 and a rear wheel 3 16 pair 320, and each wheel 316 is mounted to the body 312 of the carrier 310 by a substantially horizontal wheel drawing 322, each wheel axle 322 is a partition: each wheel 316 is directly attached to its axle 322, where each axle 322 has an integral pivot member 325 attached to the body 312 with a pivot 327. The rear wheel 316 versus the gear 326 of 320 directly engages the front wheel One of the gears 326 of 316 to 318, each gear 326 can be a 3 60 degree gear or a section of gears, as shown in Figure 。. The arrangement of the front wheels 316 to 318 is a reflection of the rear wheels 316 to 320. Therefore, if a front wheel Turn right, the corresponding rear wheel will turn left. So all wheels 316 will be correctly positioned, the front wheel 3 The 16-to-318 stern axle member 325 has a front portion 331 with another gear segment 333 at its end point that engages an idler gear 335. Therefore, if a force is applied to the handle 314 to turn the carrier 310 to the right, then The top front wheel 316 will turn to the right, which causes the pivot member 325 to rotate along the pivot axis 327, so the gear 326 will move, and the other gear 333 will cause the idler gear 335 to move the other gear 333. Turn right, and the rear wheels 316 and 320 turn left. 6 Using idle gear 335, the left and right sides of the vehicle 310 will operate synchronously. Except using the complete gear 426, and the stern shaft member 425 shortened and the same on the front and rear counter wheels. In addition, the embodiment of FIG. 6 is generally the same as that of FIG. 5, which allows the wheel 416 to rotate 360 degrees when needed, and the wheel 416 can be installed below the body 412 as shown in the figure. Similarly, FIG.
