1 to 3, the frame 1 mounted on the shoe sole (not shown) is basically formed in a plate shape spaced at equal intervals, and the left and right ends and the front and rear wheel guides 61 are formed. In the rear end of the frame 1, the lever frame 2 protruding upward is formed in one piece, and the lever 20 having the lever shaft 21 is hinged at a predetermined portion of the lever frame 2. It is configured to be rotatable about the center.

In addition, a center shaft 10 connecting the spaced frames 1 is formed at the upper end of the center of the frame 1, and the wheel shaft 60 on which the wheel 6 is mounted passes through the left and right ends of the wheel guide 61. Is installed so that the wheel shaft 60 is guided along the wheel guide 61, and in the center of the front and rear wheel shaft 60, the support 30 is installed a predetermined distance spaced by the spring shaft 31, respectively, is coiled The spring 4 is connected to each of the front and rear shafts 32 around the center shaft 10 so that the wheel shaft 60 is positioned above the wheel guide 61 by an elastic action.

In addition, the band guide 11 is connected to each of the front and lower ends of the frame 1 in the form of an shaft, and the locking guide 51 is drilled in the predetermined frame of the upper end thereof, and the locking guide 51 has a variable shaft ( 52 is installed through.

In addition, as shown in the band 3, both ends of the band 3 are fixed to the front and rear wheel shafts 60, respectively, and the lever shaft 21 via the variable shaft 52, the band guide 11, and the band auxiliary guide 12. Is stuck on.

On the other hand, the auxiliary locker 5 is installed on each of the front and rear locking shafts 50 supported by the frame 1, but connected to the inner surface of the spaced frame 1, and connected to the outer surface of the spaced support 30 It is installed in a plate shape so that it can also be rotated about a certain angle around the locking axis 50, the shape of the predetermined portion to form the same round portion 56 as the arc shape of the wheel guide 61 as shown The wheel shaft 60 can be guided and the other predetermined portion forms the variable shaft support 57 as shown in FIG. 3 to support the variable shaft 52 so as not to flow from the locking guide 51 and at the same time the lever 20. ) To maintain the tension of the band (4) even in the downward position and is formed to have a wheel shaft storage groove 53 and the variable shaft storage groove (54).

Figure 4 is a partial longitudinal cross-sectional view showing the operation sequence of the shoe structure according to an embodiment of the present invention, Figure 5 is an overall view of the state of Figure 4 (C), (A) is a wheel 6 wheel guide 61 (B) is a state in which the wheel 6 is guided along the wheel guide 61 according to the operation of the lever 20, (C) is a wheel by the upward rotation operation of the lever 20 6 shows a state located at the lower end of the wheel guide 61.
