The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which the technical parts already known will be omitted or compressed for simplicity of explanation.

Shape deformation shoe 100 of the present invention includes a first shoe sole 110, a second shoe sole 120, upper 130, heel cover 140, front cover 150 and side cover 160 It will be described with reference to the drawings shown in Figs.

The first shoe sole 110 is located at the bottom of the shoe, the first shoe sole 110 is in contact with the ground. Thus, in order to absorb the shock that comes to the foot when a person walks or runs, it can be made of a material such as rubber or silicone, and the material and shape of the first shoe sole 110 can be freely manufactured as needed.

The second shoe sole 120 is coupled to the upper portion of the first shoe sole 110 and a space is provided therein. In the inner space provided in the second shoe sole 120, a fluid such as oil or air is stored. And the heel cover 140, the front cover 150 and the side cover 160 may be stored in the inner space, respectively, the upper heel cover 140, the front cover 150 and the second shoe sole 120 Protruding holes 122 are formed to allow the side cover 160 to protrude upward.

And the upper surface of the second shoe sole 120 is formed with a pressure unit 121, unlike the other upper surface has a material that is elastic so that it can be pressed down. That is, it is preferable to have a rigid rigidity that is not pressed down even when a predetermined pressure or more is applied except for the position where the pressure part 121 is formed on the upper surface of the second shoe sole 120.

This is due to the movement of the fluid stored in the space inside the second shoe sole 120 as the pressure unit 121 is pressed by the external force, the heel cover 140, the front cover 150 and the side cover 160, respectively, the second shoe This is to provide power that can protrude upward from the sole 120.

And the heel cover 140, the front cover 150 and the side cover 160, as shown in Figures 3 and 4 to prevent the fluid stored in the inner space of the second shoe sole 120 is leaked to the outside ) Is provided with a protection film 123. The prevention film 123 is in the form of a thin film, it is preferably made of a material that can be freely deformed while preventing the flow of fluid. Therefore, when the pressure is applied to the lids by the flow of the fluid inside the second shoe sole 120, it is located between the fluid and the lids, thereby preventing the fluid from flowing out along the lids.

In addition, an elastic portion 124 is positioned below the pressure portion 121 of the second shoe sole 120 to provide a restoring force that allows the pressure portion 121 to return to its original shape. That is, after the pressure portion 121 is pressed downward by the external force and the lids protrude upward, the inner space of the second shoe sole 120 is in a low pressure state, and the pressure portion 121 is pressed downward. Is maintained. Therefore, the pressure portion 121 can be restored to the shape before the external force is applied by the elastic portion 124 such as a spring.

Upper 130 is the front and back is open, it is coupled to the upper portion of the second shoe sole 120 to cover the instep. Shape-modified shoe 100 of the present invention, as shown in Figure 1, the shape is deformed in the state having the shape of slippers. So the upper 130 is coupled to the second shoe sole 120 with the front and back open as shown in FIG.

The heel cover 140 is provided at the rear of the shoe so as to support the heel when the user wears the shoe, and is stored in the inner space of the second shoe sole 120. When the user applies an external force to the pressure unit 121 of the second shoe sole 120, the user may protrude upward to support the heel.

The front cover 150 is stored in the inner space of the second shoe sole 120, and like the heel cover 140, may protrude upward from the second shoe sole 120. The front cover 150 blocks the open front of the upper 130 as shown in FIG. 2 when raised to the outside. And it will be preferable to be made of a harder material than the upper 130 for the protection of the foot like a normal shoe.

Side cover is located on both sides between the upper 130 and the heel cover 140, respectively. Thus, when the side cover is raised along with the heel cover 140, as shown in Figure 2, it is possible to deform in the shape of a sneaker that can cover all the feet.

3 and with respect to the principle that the heel cover 140, the front cover 150 and the side cover can protrude upward from the second shoe sole 120 in the shape-deformation shoe 100 of the present invention having the configuration as described above. Referring to the drawings shown in Figure 4 as follows, it will be described using the front cover 150 for convenience.

As shown in FIG. 3, in the first slipper-shaped state, the front cover 150 is stored in the second shoe sole 120. In this state, when an external force is applied to the pressure unit 121 of the second shoe sole 120, the fluid stored in the inner space of the second shoe sole 120 is pressurized while the elastic unit 124 is pressed. The front cover 150 is pressured from the inside of the second shoe sole 120. Therefore, the front cover 150 protrudes from the second shoe sole 120.

In this state, in order to maintain the state in which the front cover 150 is raised, the movement of the front cover 150 must be prevented, so the locking protrusion 125 is formed on the inner surface of the protrusion hole 122 of the second shoe sole 120. Can be formed. Accordingly, the front cover 150 may be provided with a locking groove 151 corresponding to the locking protrusion 125. That is, when the front cover 150 protrudes upwards or more than a predetermined time, the locking protrusion 125 may be held by the locking groove 151 and may not be raised any more, thereby maintaining an elevated state.

And when the user applies a certain pressure or more in the downward direction from the top of the front cover 150 in order to insert the front cover 150 back into the inner space of the second shoe sole 120, the locking projection 125 is a locking groove ( The front cover 150 is inserted into the inner space of the second shoe sole 120 while being separated from the 151. Therefore, the locking protrusion 125 preferably has elasticity. 3, the front cover 150 is inserted into the inner surface of the second shoe sole 120 protruding hole 122 while the front cover 150 protrudes, and the locking groove ( 151 prevents the front cover 150 from rising anymore and maintains the raised state.

On the other hand, the heel cover 140, the front cover 150 and the side cover with respect to the shape-deformation shoes shown in Figure 1 and 2 for another principle that can be raised protruding from the second shoe sole 120 Figure 5 It will be described with reference to the drawings shown in, will be described using only the front cover 250 for convenience. At this time, the heel cover and the side cover also operates on the same principle.

As shown in Figure 5, the front cover 250 is stored in the interior of the second shoe sole, the front cover 250 is configured to protrude upward as the external force is applied to the footrest 221. . The foot plate 221 is configured to cover the open upper portion of the pressure cylinder 222, and a connection hole is formed in the inner bottom surface of the pressure cylinder 222. And the lower part of the pressure cylinder 222, the connection pipe 223 is coupled to the position of the connection hole. The pipe 224 extends below the connecting pipe 223, and the extended pipe 224 is inserted into the front cover 250.

In this case, a pipe groove 252 is formed in the front cover 250 to allow the pipe 224 to be inserted, and the pipe groove 252 is formed in the lower surface of the front cover 250, so that the pipe 224 is more than a predetermined depth. Is formed to be inserted.

In the pressure vessel 222, a fluid such as a gas such as air or a liquid such as oil is stored, and the side of the pressure vessel 222 is compressed so that the pressure vessel 222 is compressed when an external force is applied to the scaffold 221. It is preferable that wrinkles are formed.

In addition, a prevention film 225 is formed in the pipe 224 inserted into the pipe groove 252 formed in the front cover 250. Therefore, the fluid flowing inside the pipe 224 is prevented from escaping out of the pipe groove 252.

Referring to the process of the front cover 250 is raised by the above configuration as follows. When an external force is applied to the footrest 221 by the weight of the user as the user wears shoes, the pressure tube 222 contracts according to the applied pressure. As the pressure cylinder 222 contracts, the fluid stored in the pressure cylinder 222 moves to the connection pipe 223 through the connection hole, and then moves along the pipe 224. The fluid moved along pipe 224 is filled in pipe groove 252 as it exits pipe 224 at the end of pipe 224.

As the fluid is filled in the pipe groove 252, the front cover 250 protrudes and rises. At this time, the fluid exiting the pipe 224 is filled in the pipe groove 252 and to prevent the fluid from escaping the outside of the pipe groove 252 through the gap between the pipe 224 and the pipe groove 252. As shown in FIG. 6, a barrier layer 225 is formed in the pipe 224.

The prevention film 225 seals a gap between the pipe 224 and the front cover 250 when the front cover 250 is moved while the position of the pipe 224 is maintained. And even if the front cover 250 is moved to have a shape of a thin film in order to minimize the damage of the protective film 225.

And as the fluid comes out of the pipe 224, the front cover 250 is maintained ascending after the front cover 250 is raised and raised in the same manner as the locking projection, as shown in Figure 4 The cover 250 may be maintained in a raised state.

And when the user removes the shoe, when the external force such as the weight of the user acting on the footrest 221 is removed, the elastic means such as the spring 226 so that the footrest 221 can be restored to its original position. It can be placed inside. Therefore, the footrest 221 can be restored to the original position by the spring 226.

On the other hand, the shape-deformation shoes having the configuration as described above is deformed into the shape of the sneakers as the footrest 221 is pressed when the user wears the shoes in the slipper state, the user to maintain the shape of the slippers as needed The valve 227 and the valve plate 228 may be provided.

The valve plate 228 is disposed inside the connecting pipe 223, and the valve 227 is located outside the shoe to be operated by a user. By rotating the valve 227 by the user's operation, the valve plate 228 may block the flow of the fluid inside the connection pipe 223. That is, as shown in (a) of FIG. 7, when the user locks the valve 227, the fluid may be prevented from flowing in the connecting pipe 223 by the rotation of the valve plate 228, thereby providing a footrest ( Even if an external force is applied to the 221, the fluid located in the pressure vessel 222 does not pass through the connection pipe 223, and thus the fluid does not protrude upward of the front cover 250.

Therefore, the user can operate the valve 227, and as shown in FIG. 7A, shoes can be worn in a slipper shape when the valve 227 is locked, and as shown in FIG. Likewise, when shoes are worn with the valve 227 open, the shape of the shoes is changed from the slipper shape to the sneaker shape.
