In the drawings of the present invention will be described as fixing the shoe 50 by two

bands

104, 106 of the clip type. However, in the shoe 50, the rear fixing band 104 for fixing the side close to the ankle and the front fixing band 106 for fixing the side near the toe are buckle, which is used for a conventional belt, a velcro type that is a combination of fiber tissues. Various methods may be used, such as knotting with laces.

The rear fixing band 104 and the front fixing band 106 are configured to pass through the holes formed in the left and right sides of the sole 102 below the fixing device 100 and ascend upward from both the left and right sides.

When the present invention is used in the same way as the inline skates, the wheel built in the lower portion of the sole 102 is lowered down. Since the wheels are lowered further than the bottom surface of the sole 102, the wheels can naturally roll off the ground. If the user is not able to skate, the wheel can be put on the sole 102 and walked to the sole 102. Therefore, it can be selected and used for exercise or walking according to the user's selection.

Figure 4 is a cutaway view showing the structure of the wheel drive, Figure 5 is a cross-sectional view showing the side structure of the wheel drive, Figure 6 is a cross-sectional view showing the structure of the rotating frame, Figure 7 is a perspective view showing the structure of the lever and the upper fixing plate, 8 is an exploded perspective view showing a method of connecting two upper fixing plates.

The wheel driving unit shown in FIG. 4 is embedded in the sole 102 constituting the bottom of the fixing device 100. The wheel drive allows the wheel 110 to be moved up or down while moving or walking.

The center side surface of the sole 102 is recessed, and the rotating frame 108 is installed in this part so as to be symmetrical one by one. The rotating frame 108 is rotatably installed at a predetermined angle about the central rotating shaft 116 lying parallel to the ground, and the wheel 110 rotates at the opposite end of the central rotating shaft 116 in the rotating frame 108. It is possible to install. Therefore, the wheel 110 moves downward or upward from the sole 102 according to the rotation of the rotary frame 108.

The upper fixing plate 114 is installed on the upper portion of the rotating frame 108, the lever 112 is installed on the bottom of the upper fixing plate 114. The lever 112 moves the rotary frame 108 up and down while reciprocating by a predetermined angle.

As shown in Figures 5 and 6, the rotating frame 108 has a two-part split wheel protection (108a) in the rear to be able to fit the wheel 110 therebetween, the front is the central rotating shaft (116) ), A circular rotating shaft insert 108b through which is inserted is formed.

The center body is bent downwardly in a V shape, and the stopper 108c protrudes from the end of the bent portion. The stopper 108c is formed closer to the wheel protector 108a on the basis of the bent portion. The stopper 108c serves to prevent the lever 112 from going backwards when the wheel 110 is lowered.

The lever 112 extends from the upper side to the lower side of the rotating frame 108 as shown in FIG. 5 and contacts the upper surface of the V-shaped bent portion of the rotating frame 108. In this state, when the lever 112 is rotated to the rear of the fixing device 100, the lever 112 pushes the upper surface of the rotating frame 108 downward in a manner similar to the cam driving so that the rotating frame 108 rotates downward. do. When the lever 112 continues to rotate and meets the stopper 108c, the lever 112 stops rotating any further. At this time, the rotating frame 108 is rotated to the bottom, and the wheel 110 is to the bottom. The user may use the wheel 110 to exercise in a similar manner as inline skating.

When used for walking, the lever 112 is rotated to the front of the fixing device (100). Then, the lever 112 meets the center of the V-shaped bent portion of the rotary frame 108, that is, the upper surface of the most concave portion, and the rotary frame 108 is raised again by the elasticity of the spring 118. Therefore, the user can use it for walking like general shoes.

A spring fixing protrusion 108d protrudes from the inside of the wheel protector 108a, that is, the side of the sole 102 that is in contact with the concave portion of the side surface. One side of the spring 118 is fixed to the spring fixing protrusion 108d, and the spring 118 generates a restoring force to return the rotating frame 108 to its original position. That is, by rotating the rotating frame 108 down by rotating the lever 112, the wheel 110 comes down to be able to exercise like inline skating. When the lever 112 is reversed, the restoring force of the spring 118 is reversed. As a result, the rotating frame 108 can be used for walking while moving up.

The rotating frame 108 and the lever 112 are generally made of a high strength metal, but may be made of a plastic material having similar rigidity. And the wheel 110 is made of a general urethane or silicon material.

And the size (diameter) of the wheel 110 is the bottom of the wheel 110 above the bottom of the sole 102 when the wheel 110 is raised for use for walking, the wheel for use for exercise When lowered, the bottom of the wheel 110 should be positioned below the bottom of the sole 102. Preferably, the diameter of the wheel 110 is slightly larger than the thickness of the sole 102.

On the other hand, Figure 7 and 8 shows the structure of the upper fixing plate 114.

The upper fixing plate 114 is installed on the upper portion of the sole 102 of the fixing device 100 and serves to fix the rotating frame 108 and the lever 112. The upper fixing plate 114 is also installed one by one symmetrically on both left and right sides like the rotating frame 108.

The upper fixing plate 114 is formed with a lever fixing tool 114a into which the rotating shaft of the lever 112 is inserted at the bottom of the flat body supporting the lower surface of the shoe 50. The rotation shaft of the lever 112 is inserted into the lever fixture 114a to allow the lever 112 to rotate about a certain angle with respect to the lever fixture 114a.

In front of the upper fixing plate 114, a rotation shaft inserting portion 114b into which the central rotation shaft 116 is fitted is formed. The central rotating shaft 116 is simultaneously fitted to the rotating shaft inserting portion 108b of the rotating frame 108 and the rotating shaft inserting portion 114b of the upper fixing plate 114.

A spring fixing protrusion 114c for fixing one end of the spring 118 is formed at the rear of the upper fixing plate 114 to protrude. The lower end of the spring 118 is fixed to the spring fixing protrusion 108d of the rotary frame 108, and the upper end of the spring 118 is fixed to the spring fixing protrusion 114c of the upper fixing plate 114, respectively.

The upper fixing plate 114 is preferably embedded between the sole 102 of the fixing device 100 and the middle window thereon.

The left and right upper fixing plates 114 are provided with levers 112, respectively, and the left and right levers 112 have a long round bar shape that passes through the lever fixing tool 114a. And at the ends of the left and right lever 112, the lever connecting projection 112b and the lever connecting groove 112c is formed, respectively.

The lever connecting protrusion 112b has a shape in which the diameter of the end is slightly smaller than the center portion, and the lever connecting groove 112c is a hollow formed in the center of the end of the lever 112. The lever connecting protrusion 112b ) Is coupled in a form fitted into the lever connecting groove (112c). Therefore, if one of the left and right lever 112 is moved, the lever 112 on the opposite side is also moved together. Preferably hold the left and right lever 112 at the same time with both hands to adjust the position of the wheel 110 while moving at once.

Figure 9 is a cross-sectional view showing how the rotating frame moves in accordance with the rotation of the lever. As described above, when the lever 112 is seated in the bent portion of the V-shaped center of the rotating frame 118, the rotating frame 118 is raised by the force of the spring 118, but the lever 112 When rotated backward, the rotating frame 108 is pushed downward by the cam action of the lever 112 and rotates about a central rotation axis 116 by a predetermined angle. While the wheel 110 descends as shown in FIG. 9, the bottom of the wheel 110 descends further below the bottom surface of the sole 102.

On the other hand, Figure 10 is an exploded perspective view showing a connection method of the central rotary shaft, Figure 11 is a plan view showing a direction in which the central rotary shaft moves in accordance with the rotation of the nut.

The upper fixing plate 114 is installed in a pair on the left and right, it is necessary to adjust the width of the left and right according to the size of the shoe 50 or the fixing device (100). To this end, the center rotation shaft 116 is divided into two parts so as to adjust the distance of the left and right upper fixing plates 114, and the left and right center threads 116a are formed at the parts where the center rotation shaft 116 meets each other. That is, the right side thread 116a is formed in the center rotation shaft 116 on one side, and the left side thread 116a is formed in the center rotation shaft 116 on the opposite side. And screw the left and right two central rotation shaft 116 to one nut 120 in the center.

When the nut 120 is rotated as shown in FIG. 11 in the combined state, the left and right upper fixing plates 114 move in a direction away from or near each other. In this manner, the distance of the upper fixing plate 114 can be adjusted.

In some cases, the user may freely adjust the width of the upper fixing plate 114, but since the upper fixing plate 114 may be embedded in the sole 102 in the manufacturing process of the fixing device 100, the shoe 50 After adjusting the distance of the upper fixing plate 114 while rotating the nut 120 according to the size of the buried in the sole 102 to produce a fixing device (100).

On the other hand, Figure 12 is a partial perspective view showing a state in which the front wheel is mounted, Figure 13 is an exploded perspective view showing the structure of the front wheel.

In the above description, the wheel 110 is located at the rear of the shoe 50. In order to exercise in the same manner as inline skating, the front wheel is preferably present.

To this end, the front wheel fixing frame 122, which can be fitted with the front wheel 124, is installed in the front of the sole 102. The front wheel fixing frame 122 may be fixedly embedded or may be detachably installed from the sole 102.
