The present invention relates to a smart lower body exercise machine and a system including the same, and more particularly, to a smart lower body exercise machine having a simple structure suitable for mass production while reducing noise generated during exercise and a system including the same.

In general, examinees and office workers, etc., sit in a chair almost all day, and thus face a lack of exercise. In addition, according to the results announced by many research institutes and medical institutions recently, it is exposed to various adverse effects such as an increase in the incidence of obesity, cancer, or diabetes due to sitting for a long time.

1 is a perspective view of an existing smart lower body exercise machine, and FIG. 2 shows a case in which a user exercises using the existing smart lower body exercise machine.

The existing smart lower body exercise machine 1 may be disposed adjacent to the chair on which the user sits. The user can place both feet on the smart lower body exercise machine 1 while sitting on a chair, and exercise both feet in a direction or an angle.

As shown in FIG. 1 , the smart lower body exercise machine 1 includes a body portion 10 , a body surface portion 11 , a pedal path 12 , a connection portion 13 , a pedal portion 20 , and a pedal base bottom 21 . ), the pedal shaft base 22, the pedal connecting rod 23 and may be configured to include a support (24).

The body portion 10 is a housing constituting the exterior of the smart lower body exercise machine 1 , and can support the smart lower body exercise machine 1 .

A pedal path 12 may be formed on the body surface portion 11 .

The pedal path 12 may be formed on the body surface part 11 so that the pedal part 20 is slidable. For example, the pedal path 12 may be configured in the form of a groove having a predetermined depth on the body surface portion 11 so as to be coupled to the pedal unit 20 in the form of a rail.

The pedal path 12 may be composed of a left pedal path and a right pedal path. A left pedal and a right pedal, which will be described later, may be disposed to correspond to the left pedal path and the right pedal path, respectively.

The connection part 13 connects the left side and the right side of the body surface part 11, and the length is adjustable. As the length of the connecting portion 13 is adjusted, the width of the body surface portion 11 is changed, and correspondingly, the distance between both feet of the user and/or the distance between both legs is changed. Accordingly, the user may perform lower body exercises in various postures. In addition, the connection part 13 can be adjusted to suit the user's body type or body size.

The pedal unit 20 is disposed on the body surface portion 11, is coupled to the pedal path 12 of the body surface portion 11, and can slide along the pedal path 12 in a straight line.

A user's foot may be positioned on the pedal unit 20 . To this end, the pedal unit 20 may include a left pedal and a right pedal corresponding to the left foot and the right foot, respectively. With such a configuration, the user can exercise while putting his or her feet on the pedal unit 20 and sliding.

A user's foot is disposed on the pedal base bottom 21 . If the user wears the smart lower body exercise machine 1 on the feet, the pedal base floor 21 comes into contact with the sole surface of the user.

The pedal base bottom 21 is rotatably fastened to the pedal connecting rod 23 . In this case, the user may rotate the pedal base bottom 21 on a horizontal plane to collect or spread the heels or to rotate the ankles.

The pedal shaft base 22 may slide along the pedal path 12 .

The pedal connecting rod 23 may be tilted at various angles with respect to the central axis, similar to the joystick. In this case, the pedal connecting rod 23 rotates and tilts the pedal unit 20 at various angles to help stretch the user's lower body muscles (especially the calves and ankles) and stimulate many fine muscles connected thereto. . Such fine muscle movements have the effect of preventing in advance the muscle hardening and pain caused by maintaining a specific posture for a long time.

The support 24 supports each of both feet so as not to deviate from the pedal unit 20 during lower body exercise. To this end, the support 24 may include a left support for supporting the left foot and a right support for supporting the right foot.

As shown in FIG. 2 , the user can slide or rotate the pedal unit 20 in a straight direction, or tilt the pedal unit 20 at various angles, in a state where each of both feet is placed on the corresponding pedal unit 20 . Also, these operations may be performed in combination.

In addition, the user may exercise by pushing and pulling the two pedal units 20 at the same time, or alternately pushing and pulling each other. In this case, the user can freely adjust the exercise part or intensity.

In this way, the user can perform various lower body exercises using the existing smart lower body exercise machine 1 while sitting on a chair. However, the existing smart lower body exercise machine 1 has the following problems.

First, noise is generated as the pedal unit 20 is moved. In the conventional smart lower body exercise machine (1), the pedal unit 20 is engaged with the pedal path 12 formed in the form of a groove, and moves in a straight line along the pedal path 12 in a state in which it is engaged with the pedal path 12 . In this case, noise is generated by friction with the pedal path 12 during linear movement.

Second, many defects occur in mass-producing the pedal unit 20 . When the pedal unit 20 slides, pressure by inertial force and frictional force is applied. Therefore, in order to prevent the pedal unit 20 from being separated from the pedal path 12 even in this state, the pedal unit 20 must be precisely and firmly coupled to the pedal path 12 . At the same time, so that the sliding movement can be easily performed, the pedal unit 20 and the pedal path 12 should be flexibly coupled without being too stiff. Therefore, the process of manufacturing the pedal unit 20 is labor intensive and difficult, and is a factor in which many defects occur during mass production.

Third, the noise is amplified by the pedal path 12 formed in the body portion 10 . As described above, the pedal path 12 is formed in a groove shape, and a space is formed inside the lower end of the pedal path 12 . Accordingly, the body portion 10 itself functions as a ringer, and the noise generated when the pedal portion 20 moves is amplified.

The problem to be solved by the present invention is to change the structure and components so as to reduce the noise generated by friction between the pedal part and the pedal road when moving by wearing the pedal part in the existing smart lower body exercise machine. It is to provide a smart lower body exercise machine and a system including the same.

In addition, the problem to be solved by the present invention is to mass-produce the configuration and manufacturing method of the existing smart lower body exercise machine so as to reduce the defects that occur frequently when mass-producing the pedal part, which is a key component of the existing smart lower body exercise machine.
