DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to an accessory for a bicycle, and more particularly to a training wheel assembly or an auxiliary wheel assembly for riding The bicycle can control dynamic lateral instability. [Prior Art] The use of a pair of auxiliary side wheels is well known in the art, and the pair of side wheels are detachably coupled to a bicycle rear axle or across the rear % axle to control its dynamic laterality. stability. The stability of the bicycle is dynamically enhanced by increasing the speed of the vehicle. However, the lateral stability of the bicycle is difficult to maintain at low vehicle speeds, especially for children and other inexperienced people in bicycle riding technology. These side wheels are most commonly used for children who are undergoing basic training in riding bicycles and those who have just started riding from 4 cars and have not yet achieved sufficient lateral stability. The presence of several auxiliary side wheels has the problem of including rigid connecting mechanisms that connect them to a conventional bicycle. This rigid connection mechanism has proven to be disadvantageous in several 'it conditions. For example, uneven ground will often result in one of the side wheels being high

In other cases, the rear self-propelled wheel can be raised relative to the ground plane and the rider temporarily loses propulsion capability. In addition, when the rider turns, the stability of the bicycle will be destroyed again because the bicycle will not be properly tilted due to the rigid connection of the side wheels. The above problems have been solved by several patents, including the suspension mechanism between the 102022.doc 1300038 driving and the auxiliary wheels. U.S. Patent No. 5,492,354, issued to RAINEY, which is incorporated herein by reference in its entirety, the utility of the utility of the utility of the utility of the present invention. The axes of the coil springs are in line with each other and have an offset below the rear axle and are parallel to the rear axle. Therefore, even if the coil spring allows the training wheels to move upward, the training wheels can be pulled back against the action of the spring. Therefore, the disadvantage of the device disclosed by RAINEY is that the friction generated by the uneven terrain can cause one of the two auxiliary wheels to be pulled back and thus resist forward movement, causing the bicycle to turn inadvertently. Another coil spring suspension system for attaching an auxiliary wheel assembly to a bicycle rear axle is disclosed in U.S. Patent No. 2,45, issued to M. An L-shaped bracket interconnecting the two axles maintains the auxiliary axle axially downwardly offset from the bicycle bull gear. An upwardly inclined, adjustable length coil spring member movably interconnects the hub of the auxiliary wheel to the bicycle rear axle. The MOLLER device is expensive to manufacture and is susceptible to damage due to its many separate components. U.S. Patent No. 2,793,877 to the name of U.S. Patent No. 2,793,877, which is incorporated herein by reference. The vertical struts of the L-shaped spring blades and the vertical struts of a second, rigid L-shaped blade are anchored to the bicycle rear axle. An adjustable length vertical member movably connects the transverse struts of the rigid blade to the rear flexible blade, wherein the rigid struts of the rigid blade overlie the lateral axle struts of the flexible blade. For the present agricultural device 102022.doc 1300038, the auxiliary axle and the rear axle of the bicycle are = because the horizontal bracket is limited to a downward movement with respect to the horizontal pillar of the rigid L-shaped blade. Keep it flush with the trunk of the bicycle. In order to prevent the slab from being used in the grinding, the front, the rear, and the rear of the water are required to use a second rigid blade and a plurality of struts. In all of the above patents, the auxiliary wheels are practical, but they have varying degrees of complexity 'because they either require multiple parts (;

The bicycle 10 is equipped with a pair of auxiliary side wheels 16, which have a smaller diameter than the rear wheel 14. The wheel 16 is positioned on each side of the rear wheel 14. The wheels 16 are rotatably mounted on their respective auxiliary side wheel attachment members 18 that are securely and removably anchored to opposite ends of the bicycle axle 24 of the bicycle. The connecting members 18 include a C-shaped compliant structure 27 to thereby connect the auxiliary side wheels 16 to the bicycle frame 12. 3 and 4 show that the connecting member 18 has an upper vertical portion 20, an intermediate C-shaped compliant structure 27 and a lower horizontal auxiliary wheel spindle end portion 28. As shown in Fig. 4, all of the elements 18, 20 and 28 are coplanar with each other in the end view, but form an l-shape in their natural unbiased state in plan view as shown in Fig. 3. Thus, the C-shaped compliant structure 27 enables portions 20 and 28 to move toward or away from each other. Figure 3 shows the connecting member 18 with the C-shaped compliant structure 27 in an unloaded or unbiased state, wherein the portions 20 and 28 are substantially at right angles to one another. In the unloaded state of Figure 3, the C-shaped compliant structure 27 is bent by the application of force and enables portions 20 and 28 to move toward each other once applied to portions 2 and/or 102022.doc 1300038 28 The removal of the force will also bring the portions 2 and 28 to their initial unbiased right angle state as shown in FIG. The C-shaped compliant structure 27 has a central axis parallel to the direction of travel of the bicycle and an opening 25 at an angle between the vertical portion 2 〇 and the mandrel portion 28, the opening being indicated by acting substantially The portions of the right angle segment are formed at the shortest angle to the C-shaped compliant structure 27 that acts as a vertex. • It should be noted that the C-shaped compliant structure 27 can be relatively closed, as shown in Figure 3, but can be more open, as shown in Figures 10 and 11. In this case, the % connecting member 18 is further preferably provided with a plurality of ribs 51 or fins which increase the stiffness of the C-shaped compliant structure 27. Thus, the invention is not limited to a closed C-shaped structure, and the invention is intended to include openings of any angle. In fact, the angle of the opening of the c-shaped structure can be greater than 90 degrees without affecting the mode of operation of the present invention. The embodiment shown in Figures 10 and 11 also provides a downwardly extending portion 53 that is secured to the downwardly extending portion. In addition, the c-shaped structure is made to have a hardness of more or less by removing the material of the 5 ich C-structure 27, which will be apparent to those skilled in the art. Therefore, the connecting member 18 can accommodate the weight of the person using the connecting member 18. A higher hardness structure 27 will be used for a heavier person, and a lower hardness structure 27 will be used for a lighter person. The connecting member 18 of the present invention is also adapted to prevent the member 18 from being twisted to a large angle, thus improving safety. Therefore, when the bicycle is moving forward, if the wheel 16 hits an object such as a stone, the member "will resist the backward movement. The side wheel connecting member 18 is molded, shaped or shaped into one of the desired shapes. .doc -10- 1300038 Also kept in contact with the ground G for propelling the bicycle 10. If the ground plane G is not flat, the side wheels 16 can move up and back down to compensate for unevenness of the ground. The material or material is made by his appropriate elastic material. /, Such an auxiliary wheel assembly will increase the safety limit of the bicycle rider, and the rider will therefore have more confidence in his riding ability and can master it faster. : ############################################################################################### For reasons of safety and for training purposes, this continuous height adjustment is advantageous because they allow the layman to increasingly develop the lateral instability of the bicycle at low speeds while at the same time being comfortable. The ride safety margin is maintained. While the invention has been described above by way of a preferred embodiment thereof, it should be noted that any modification of the preferred embodiment is not considered to be within the scope of the appended claims. Variations and modifications of the nature and scope of the present invention are made. For example, the description has been made with reference to the use of the connecting member 18 for a bicycle, but the connecting member 18 can be used with other structures that require temporary or permanent stability.
