Is formed. The other side of the lever member 180 is in contact with the other side of the friction member 170, the other side of the lever member 180 and the other side of the friction member 170 of the elastic member 192 to be described later The contact is always maintained by the elastic pressing force.

The elastic member 192 elastically presses the friction member 170 in a first rotation direction A in which contact between the friction member 170 and the wheel 123 is released. The elastic member 192 is a spring fitted to the pin member 194 coupled to the base member 160, and in this embodiment, a torsion spring is preferably used. One end of the elastic member 192 is supported by the base member 160, the other end of the elastic member 192 is provided with an elastic member 192 so as to be supported by the other side of the friction member 170. Therefore, the elastic member 192 elastically presses the friction member 170 in the first rotation direction A in which the friction member 170 and the wheel 123 are released from each other, and the elastic pressing force of the elastic member 192 is applied. By this, the lever member 180 and the friction member 170 are always in contact.

First, the shaft member 131 is positioned so that the protrusion 132 formed on the shaft member 131 is coupled to the recessed portion 133 formed on the first support member 121, and the shaft member 131 is positioned on the first rotation axis ( rotate around b1). Since the shaft member 131 and the first support member 121 are coupled to each other, the first support member 121 is rotated by the rotation of the shaft member 131, and thus the base block 110 is formed around the first rotational axis b1. Will be rotated. Accordingly, the wheel assembly is located at the second position (see the position shown in FIG. 2) where the wheel 123 is drawn out from the inner space 157 of the housing 156. Since the friction member 170 and the wheel 123 are in contact when the wheel assembly is in the second position, the brake assembly of the present invention may perform a brake function when the wheel assembly is in the second position.

With the wheel assembly in the second position, if the wearer of the shoe 100 wants to stop the rotation of the wheel 123, the calf 1 is retracted in a direction C opposite to the running direction of the wheel 123. . The retracted calf 1 is in contact with the curved portion 182 provided on one side of the lever member 180, the external force is transmitted to one side of the lever member 180 by the calf (1).

Thereafter, the lever member 180 rotates in the first rotation direction A about the second axis a2. The other side of the lever member 180 pushes the other side of the friction member 170, and the friction member 170 is friction member 170 about the first axis a1 by a force applied by the lever member 180. ) And the wheel 123 is rotated in the second rotation direction (B). The friction member 170 and the wheel 123 are in contact with each other so that the rotation of the wheel 123 is stopped due to the friction force between the friction member 170 and the wheel 123.

To release the brake function, the calf 1 is dropped from the curved portion 182. If there is no external force transmitted to the friction member 170 through the lever member 180, the friction member 170 and the friction member 170 with respect to the first axis a1 due to the elastic pressing force of the elastic member 192. The wheel 123 rotates in the first rotational direction A in which the contact is released. Therefore, the friction member 170 and the wheel 123 are no longer in contact with each other, and the skating function using the shoe 100 is enabled by rolling the wheel 123.

The brake assembly according to the present embodiment configured as described above has a friction member in contact with a rotating wheel and a long lever member for rotating the friction member in a direction in contact with the wheel, thereby providing a Even if a small force is applied, a large torque is transmitted to the friction member that is in contact with the wheel, so that the wheel can be effectively stopped even with a small force.

On the other hand, the shoe according to the present embodiment configured as described above, in the wheel-mounted shoes, by providing a brake assembly so that the wearer of the shoe can easily stop the rotation of the wheel at any time, the speed due to the non-installation of the brake assembly It is possible to obtain an effect that can prevent the safety accidents caused by the inability to control.

In addition, the shoe according to the present embodiment is manufactured so that the lever member to which the external force is applied is in contact with the calf portion of the shoe wearer, so that the running of the wheel can be easily carried out simply by retracting the calf portion in the opposite direction to the driving direction during driving. The effect of stopping can be obtained.

In addition, the shoe according to the present embodiment is detachably coupled to the lever member provided with an external force capable of stopping the wheel, so that the wearer who does not use the skating function during walking or who is familiar with the skating and brake functions is no longer cumbersome. When a neat lever member is not required, the effect of being able to simply wear the shoe can be obtained by separating the lever member from the shoe.
