## Abstract

A leg care apparatus includes a main body configured to provide an action space in which a leg is accommodated, a bottom module which is placed on a bottom surface of the main body and in which a component for a foot bath is accommodated, and an action space adjustment module configured to adjust a size of the action space.

## Claims

### Claim 1

A leg care apparatus comprising:
a main body configured to provide an action space to accommodate a leg;
a bottom module disposed at a bottom surface of the main body and in which a component for a foot bath is accommodated; and
an action space adjustment module configured to adjust a size of the action space,
wherein the action space adjustment module comprises a side module in which at least a portion of a front surface of the action space is defined and which opens and closes an inlet through which the leg is inserted into the action space.

### Claim 2 (depends on 1)

The leg care apparatus according to claim 1, wherein the action space adjustment module comprises an upper module in which at least a portion of a top surface of the action space is defined and which opens and closes an inlet through which the leg is inserted into the action space.

### Claim 3 (depends on 2)

The leg care apparatus according to claim 2, wherein the upper module is slidable vertically with respect to the main body.

### Claim 4 (depends on 2)

The leg care apparatus according to claim 2, further comprising a knee care part configured to care a user's knee disposed at the upper module.

### Claim 5 (depends on 1)

The leg care apparatus according to claim 1, wherein the side module is rotatable with respect to the main body.

### Claim 6 (depends on 5)

The leg care apparatus according to claim 5, wherein the side module is supported by the bottom module.

### Claim 7 (depends on 1)

The leg care apparatus according to claim 1, further comprising a contact pad configured to conduct and transfer a temperature atmosphere by contacting a user's body disposed at at least one of the main body, the action space adjustment module, and the bottom module.

### Claim 8 (depends on 1)

The leg care apparatus according to claim 1, further comprising an atomizer configured to provide mist into the action space.

### Claim 9 (depends on 8)

The leg care apparatus according to claim 8, wherein the atomizer comprises at least one of an ultrasonic spray device and a heating spray device.

### Claim 10 (depends on 1)

The leg care apparatus according to claim 1, further comprising a bottom supporter configured to allow movement of the leg care apparatus.

### Claim 11 (depends on 10)

The leg care apparatus according to claim 10, wherein the bottom supporter includes two kinds of wheels having at least different sizes.

### Claim 12 (depends on 11)

The leg care apparatus according to claim 11, wherein a large wheel having a relatively large size among the two kinds of wheels is installed at a rear portion of the bottom module.

### Claim 13 (depends on 12)

The leg care apparatus according to claim 12, wherein the large wheel is placed on each of both left and right sides of the bottom module.

### Claim 14

A leg care apparatus comprising:
a main body configured to provide an action space to accommodate a leg;
a bottom module disposed at a bottom surface of the main body; and
at least one of an upper module movably coupled to an upper portion of the main body and a side module movably coupled to a front portion of the main body so as to adjust an inlet, through which the leg is inserted.

### Claim 15

A leg care apparatus comprising:
a main body configured to provide an action space to accommodate a leg;
a bottom module disposed below the main body to support the main body; and
a bottom supporter configured to allow movement of the leg care apparatus,
wherein the bottom supporter includes two kinds of wheels having at least different sizes wherein a movable wheel having a relatively small size among the two kinds of wheels is installed at a front portion of the bottom module and is rotatable,
wherein a user holding portion of the leg care apparatus is more adjacent to the movable wheel than the other of the two kinds of wheels.

### Claim 16 (depends on 15)

The leg care apparatus according to claim 15, wherein the movable wheel comprises:
a wheel;
a wheel housing configured to support the wheel; and
a rotation support shaft configured to vertically connect the wheel housing to the bottom module, the rotation support shaft being configured to allow rotation of the wheel housing in a left and right direction.

### Claim 17 (depends on 16)

The leg care apparatus according to claim 16, further comprising an elastic member configured to connect the wheel housing to the bottom module, the elastic member being configured to provide restoring force by which the wheel housing returns to an installation angle.
