The guide groove 13 of the housing 10 is shifted. Then, the lower end of the locking plate 41 is in contact with the upper end of the guide protrusion 24 of the roller assembly 20, so that the position of the roller assembly 20 is drawn out to the lower portion of the sole (B).

Subsequently, as shown in FIG. 10E, the brake 23 accommodated in the frame 21 of the roller assembly 20 is rotated out of the frame 21 to be taken out, and then the fixing groove 23a is removed from the frame 21. ) By fixing the brake 23 in the withdrawn position. This allows the roller blade 1 to function as a normal roller blade mounted to the sole B of the shoe S. FIG.

On the other hand, the storage of the roller assembly 20 after the use as a roller blade proceeds in the reverse order of the above-described drawing, first separating the brake 23 from the frame 21, and then rotates the inside of the frame 21 I receive it. Next, when pulling out the handle 42 of the rocker 40 as in the above-described withdrawal, the allowable groove 44 coincides with the guide groove 13 of the housing 10, and in this state the roller assembly 20 When stepped lightly), while the spring 27 is compressed by an external force, the roller assembly 20 is raised to enter the inside of the housing 10.

Subsequently, when the external force applied to the handle 42 of the rocker 40 is removed, the rocker 40 returns to the initial position by restoring elasticity of the spring 43, and thus, as shown in FIG. The lower ends of the guide protrusions 24 enter and engage the locking grooves 45 of the locking plate 41 such that the roller assembly 20 is fixed in a state accommodated in the sole B. Therefore, it can also function as a normal shoe without a roller blade at the bottom of the sole B. FIG.

As described above, according to the present invention, the roller blade is normally stored in the sole of the shoe and worn like a normal shoe, and the roller blade can be easily taken out and used only when necessary. And roller blade functions. Therefore, there is no need to separately provide shoes and roller blades as in the prior art, and in particular, there is no need to carry the roller blades separately, and there is no need to wear shoes and roller blades alternately depending on the location conditions.

Therefore, the present invention has a very excellent effect of greatly improving the functionality and economy and convenience of shoes.
