Description

  The present invention relates to a roller racer. In particular, rear wheel units that can swing freely are installed at the rear ends of the two fixedly installed left and right carrier bars. The rear wheels of the left and right rear wheel units are used by the user to apply force to the left and right carrier bars with both feet. By adding, it automatically touches the left and right to advance into S shape. Furthermore, the front wheel, vertical post, and handle can be combined to twist the body, buttocks, hands, and both feet alternately, or by applying force at the same time, it can be operated in various forms. This article is a roller racer characterized by being able to perform an interesting and entertaining exercise.

  Many of the conventional roller racers arranged in a triangle are those shown in FIG. 1 or FIG. In the conventional roller racer of FIG. 1, the support post 1 is connected and fixed to the front ends of the left and right carrier bars 10 via joints 11. The support post 1 is fitted into the vertical post 20, and the upper end of the vertical post 20 is connected to the upper end of the vertical post 20. A handle 21 is installed, and a front wheel 23 is installed at the lower end via a front fork 22. Then, a step 12 and a rear wheel 13 are installed at the rear ends of the left and right carrier bars 10, respectively. When in use, stand on the left and right step 12, hold the handle 21 with both hands, twist the handle 21 or twist the body, and swing the vertical post 20 left and right to move. Along with this, the front wheel 23 swings sideways, moves forward in an S-shape, and the entire vehicle body slides by the auxiliary movement of the rear wheels 13 on both sides, so that a movement effect can be obtained.

  In the conventional roller racer of FIG. 2, the front ends of the left and right carrier bars 10 are axially connected to the column post 1 while being opened and closed inside and outside via the shaft pipe 101. The front end of the column post 1 is axially connected to the vertical post 20, and a handle 21 is installed at the upper end of the vertical post 20, and a front wheel 23 is installed at the lower end. The two left and right carrier bars 10 are each provided with step 12, and the rear wheel unit 30 is provided at the rear ends thereof. Among these, the rear wheel unit 30 is provided with a rear fork 301 for installing the rear wheel 302. The upper end of the rear fork 301 is axially connected to the rear ends of the left and right carrier bars 10 through a shaft pipe 3011 in a vertical state. The lower end pulls 10 by the spring 303 through the extension plate 3012, and gives the rear fork 301 and the rear wheel 302 an elastic action to return to the original at any time. At the time of use, the both legs placed on the step 12 are simultaneously unfolded toward the outside, and further, the action of closing the inwards toward the inside is performed, whereby the left and right carrier bars 10 are repeatedly opened and closed. The rear wheel unit 30 swings sideways to advance the rear wheel 302 into an S shape. Thereby, the advancement of the vehicle body and the exercise effect of both feet can be obtained.

  However, in the case of the technique shown in FIG. 1, the movement of the roller racer is driven by the left and right deflection of the front wheel 23, and both rear wheels 13 that do not swing sideways move only in an auxiliary manner. The movement of the front wheel 23 swinging left and right also depends on the swing of the vertical pipe 20. Therefore, since the difficulty of operation becomes high, power is required, and the operation is difficult to perform smoothly, the user may experience a sense of frustration or lose interest.

  Further, in the case of the technique of FIG. 2, the shaft pipe 3011 of the rear fork 301 that is axially connected is installed vertically when the step 12 is closed with both feet (shown in FIGS. 3 and 4). In combination with the movement of the rear wheel unit 30 that can not be automatically returned to the original, it is forcibly restored with the help of the spring 303. This employs a system in which the vehicle body is moved by opening and closing the left and right carrier bars 10 outward and inward by an action in which both feet are simultaneously deployed outward and an action in which the legs are closed inward. Although this method improves the disadvantage that the carrier bar and the two rear wheels shown in FIG. 1 cannot swing sideways when both are fixed, the left and right carrier bars 10 are always harmonized with both feet. If there is no opening / closing movement, the vehicle body cannot be driven and moved. Therefore, during operation, it is difficult to apply force, it is difficult to perform the operation, and the posture is also unfavorable. When the vehicle body is bent, both feet are too wide open, which is dangerous. In particular, the action of the spring 303 forcibly returning the rear wheel unit 30 prevents the driving force of the rear wheel 302 and adversely affects the sliding speed and smoothness of the vehicle body. Based on these points, the present invention aims to solve the problems in the prior art and provide a roller racer that is easy to operate.
