[Problems to be solved by the invention]

 However, the transmission member of the conventional roller skates is mainly composed of two rollers, but such a structure is easily associated with a bicycle, and a user having a poor sense of balance does not intend to purchase the bicycle. As a result, roller skates having three roller electric members appeared on the market, giving consumers one more option, but found that the following drawbacks occurred when using them.

One of the drawbacks is that the front rollers tend to bite when turning. Referring to FIGS. 1 and 2 which show a change in the direction of the front roller of the conventional three-roller roller skate, when the roller skate goes straight, all the springs on both the left and right sides are in a non-started state. When the user changes direction, the spring at one end is compressed and the spring at the other end is loosened, and the two rollers on the left and right are rotating concentrically, so that the front part which is compressed in the spring The angle between the roller and the bearing is too small, so that the front roller is liable to bite, and as a result, may fall.

Another drawback is that the rear roller tends to slip. Since the rear roller is a cylindrical body, it cannot maintain a good contact area with the ground during the rotation of the roller skate, so that the operation of the front and rear rollers causes a biased redirection, and the rear roller Due to the low position and configuration restrictions, it is not possible to adjust the direction in which to move, so that the rear rollers will slip during travel, affecting stability.

[Means for Solving the Problems]

 In view of this, the inventor of the present invention made use of the experience of designing sports and leisure equipment for many years, repeated research on design improvement, passed many tests, and finally achieved the present invention "the structural improvement of roller skates". Was created.

[0007] Therefore, a main object of the present invention is to provide a vertical surf talc and an adjustment spring set on the upper side of the base to prevent the roller skate from biting when the direction is changed, and to prevent the roller skate from falling. It is to greatly improve stability and practicality.

[0008] Another object of the present invention is to make the rear roller of the roller skate a sphere close to a perfect circle, and the spherical roller can contact the ground at any angle, thereby making the running roller skate more stable. It is to make it.

[0009]

The roller skate according to the present invention includes a skateboard mainly composed of a reinforcing agent and three rollers for driving the skateboard, and a roller at the front of the skateboard. The two rollers are arcuate discs, which are connected and supported by bearings, and are provided with screws on the end faces of the pedestals, which consist of two wave-shaped talc, base and adjusting spring sets. When the user changes direction, the two wave-shaped talcs are closed by receiving the pressure of the base and the base of the bearing. The two talc rotate along the wave streaks of the main body, and when the turning handle is not subjected to force, the two talc are pressed by the spring and the talc returns to the original closed state, and the spherical shape The rear roller is fixed to the rear with a positioning rod. The diverter, which can be properly mounted on the rear side of the base, can be stored in two steps with an adjustment ring, which is convenient and does not take up space when storing roller skates.

A pedestal 21 is provided on the bearing 22 connecting the front roller 23, and a screw 25 is provided at the center of the pedestal 21. The screw 25 is provided with the upper and lower wave-shaped talc 32, the base 11, and the spring 43. It is penetrated and tightened with an adjustment nut 41. The rear roller has a spherical shape close to a perfect circle, can maintain a good contact surface with the ground, and does not generate slip.

At the same time, referring to FIGS. 7 and 8, the end face of the pedestal 21 of the bearing 22 is provided with a control rod 24 which is tightly combined with the control groove 321 of the lower wave talc 32. The locking groove of the talc 31 can be set on the base 11. The upper and lower wave talc 32 is kept in close contact with each other, and when the user swings the turning rod 51, the two talc move in the opposite direction along the trajectory of the wave, and the spring 43 on the base 11 is moved. Is compressed by the two talc being pushed open. When the turning rod 51 receives no force, the spring 43 returns the two talc to the original closed state by its elasticity, and the roller skate runs straight.

Still referring to FIGS. 5 and 6, when the front roller 23 changes direction, the turning radius of the front roller 23 is large because the front roller 23 and the bearing 22 maintain the original vertical angle. However, it does not bite and fall.

Referring to FIGS. 9 and 10, the turning bar 51 is controlled by an adjusting ring 52 so as to be folded or opened in two steps, and set in the lower end of the turning bar 51. A screw 55 is provided. When folding the direction change rod 51 on the pedal 12, first loosen the set screw 55 in the direction change rod 51, and fold it on the pedal 12 with the tightening bolt 54 in the base 11 as a fulcrum. Since it is only necessary to tighten the set screw 55, the operation is simple and the folding effect which is labor-saving is achieved.

Further, a brake plate 61 is attached to the rear plate 13. The brake plate 61 stops mud and sand, and when the user has an emergency, steps on it, and the friction between the brake plate 61 and the spherical roller 132 can provide a deceleration effect. Further, a recovery spring 62 made of an elastic material is provided below the brake plate 61. When the recovery spring 62 receives no external force, the recovery spring 62 moves the brake plate 61 to the original distance from the spherical roller 132. Roller skates are no longer restricted because they return to normal. In order to prevent the adhesion of mud and sand, the talc and screw 25 of the roller skating of the present invention are provided with a talc dust cover 33 and a screw dust sleeve 34, respectively. Rusting or unrotatable condition can be prevented.

In addition, the angle between the adjusting spring set of the roller skate and the central axis of the skate body according to the present invention can determine the turning radius of the roller skate, and the larger the angle, the smaller the angle (less than 90 degrees). ), The turning radius of the roller skate is smaller, and conversely, the smaller the pinch angle, the larger the turning radius. Therefore, the present invention adjusts the included angle of the center axis of the adjusting spring set and the roller skate body to any angle between 0 ° and 90 ° according to the user's need for different turning radius. It is configured so that
