The present invention relates to an infant exercise machine. More specifically, it is possible to perform a movement function by pulling an operation cable by using a movement load by an elastic force, and by exercising a movement function conveniently by wearing it on the body, It is possible to increase the movement time and adjust the strength of the operation cable to the traction force so that the movement function can be performed with various strengths. In particular, The present invention relates to an infant exercise apparatus which can perform exercise more intensively and intensively by enhancing exercise inducing function through comparison with other users.

In general, the athletic scholars differ significantly in the intelligence of children who have systematically received physical activity during childhood and those who are not. The children in rural areas who have more play than urban children have higher emotional and intelligence indices Results presentation is an example of indirectly showing the effectiveness and necessity of physical education for children.

In addition, according to reports, the growth of children and infants is important, of course, but the body's growth is promoted in a balanced manner when the body movements such as touching and running are steadily maintained. Therefore, children are stretching, running or bumping to give a healthy stimulus to the organs of the body, and this stimulus plays a role in the movement, so that growth is promoted than children of the same year.

In general, urban children living in densely populated areas like apartments do not have enough room to play, and eventually play with computer games or toys indoors, especially in the case of computer games. The worse is that the mental disorder such as paranoid is caused when the interest is over.

Therefore, there is a demand for a fitness apparatus which can promote healthy growth by promoting the stimulation of the body sufficiently in the room, especially the ordinary adult, and especially the child who is growing, so as to maintain the healthy body and to promote the growth.

However, the presently used baby exercise apparatuses have a problem that they are not used for a long time because the exercise function is strengthened or the exercise effect is not exercised properly or only the simple repetitive exercise function is performed.

For example, the first elastic member 410 may include a spiral (not shown) having a center portion coupled to the rotation shaft 231 of the first rotary drum 210 and an outer end portion coupled to the first rotary drum 210, It can be applied as a spring. Likewise, the second elastic member 420 may also be applied as a spiral spring whose central portion is coupled to the rotation shaft 231 of the second rotary drum 220 and whose outer end portion is coupled to the second rotary drum 220.

The first and second operation cables 310 and 320 are wound around the first and second rotary drums 210 and 220 in a state where the first and second operation cables 310 and 320 are coupled to the first and second rotary drums 210 and 220, And the other end is disposed in an outer space of the case 100, and a separate operating knob 140 is engaged. One end of the first actuating cable 310 is wound around the first rotary drum 210 so that the other end thereof is exposed to the outside of the case 100. The second actuating cable 320 has one end connected to the second rotary drum 220, And the other end is exposed to the outside of the case 100. The first actuating cable 310 and the second actuating cable 320 may be disposed so that they are externally exposed in opposite directions to each other in the case 100.

5, when the first operating cable 310 is pulled to the outer space of the case 100 so as to be unwinded from the first rotating drum 210, the first rotating drum 210 is rotated When the first rotary drum 210 rotates to return to the original state by the elastic rotation restoring force of the first elastic member 410 in this state, the first operation cable 310 is wound again on the first rotary drum 210 . Similarly, when the second actuating cable 320 is pulled to the outer space of the case 100 to be unwound from the second rotary drum 220, the second rotary drum 220 is configured to rotate, and in this state, The second operation cable 320 is wound around the second rotary drum 220 when the rotary drum 220 rotates to return to the original state by the elastic rotation restoring force of the second elastic member 420.

2, in a state in which the user wears the case 100 on the user's body using the fixing band 130 as shown in FIG. 2, The first and second rotary drums 210 and 220 are rotated by the first and second elastic members 410 and 420 in the process of pulling the first and second operation cables 310 and 320 while holding the first and second operation cables 140 and 140, Since the elastic rotation restoring force acts on the first and second rotary drums 210 and 220, a motion load is generated in the process of pulling the first and second operation cables 310 and 320, thereby performing a movement function.

At this time, the operation cables 310 and 320 may be pulled in the horizontal direction as shown in FIG. 2 (a), but may be pulled in the upward sloping direction or the downward sloping direction as shown in FIG. 2 (b) By varying the traction direction, various exercise effects can be exhibited.

As shown in FIG. 5, the first and second elastic members 410 and 420 may be formed in the form of a spiral spring. In this case, the first and second elastic members 410 and 420, 1 and the second operation cables 310 and 320 are pulled to be unwinded from the first and second rotary drums 210 and 220 so that the first and second rotary drums 210 and 220 rotate in the direction The elastic rotation restoring force of the spiral spring acts to generate the elastic rotation force in the direction of returning the first and second rotary drums 210 and 220 to the original state. Accordingly, when the pulling force on the first and second operation cables 310 and 320 is released, the first and second rotary drums 210 and 220 are rotated in the direction of returning to the original state by the elastic rotation restoring force, The operation cables 310 and 320) are wound on the first and second rotary drums 210 and 220 again.

In the above description, two rotary drums 210 and 220, elastic members 410 and 420, and operation cables 310 and 320 are provided. However, only one rotary drum 210 and two actuating cables 310 and 320 may be provided. The exercise may be performed in the same manner as described above. Likewise, in the following description, even if it is described that two components are provided in the following description, they may be constituted by only one component, and the following description is not particularly described.

Meanwhile, the infant exercise machine according to an embodiment of the present invention may be configured such that the size of the pulling force on the first and second operation cables 310 and 320 required for the rotational movement of the first and second rotary drums 210 and 220) And an intensity control module 500 that can be operated by the user so as to be able to adjust the intensity.

The intensity control module 500 includes an operation knob 510 mounted on the front surface of the case 100 so as to be rotatably operated by a user and an operation knob 510 mounted on the front surface of the case 100 for rotating the first and second rotary drums 210 and 220, And first and second strength adjusting means 520a and 520b for adjusting the magnitude of the traction force on the first and second operation cables 310 and 320 respectively by friction force) 2 strength adjusting means 520a, 520b).

The operation knob 510 is formed in a ring shape and is configured to be rotatable in accordance with the intensity adjustment step. The operation force transmitting means 530 may be composed of, for example, a plurality of gears, and transmits the operation force of the operation knob 510 to the first and second strength adjusting means 520a and 520b. Of course, it can be configured in various ways using various mechanical elements such as a plurality of connecting links, chains, and the like rather than a plurality of gears.

The first and second strength adjusting means 520a and 520b are provided with friction pads 521 that rotate in association with the first and second rotary drums 210 and 220 when the first and second rotary drums 210 and 220 rotate, And a pressing body 522 which is arranged to be in contact with the friction pad 521 and can move toward the friction pad 521 by rotating the operation knob 510 so that the contact force with the friction pad 521 is adjusted, .

The first and second strength adjusting means 520a and 520b may further include a rotating plate 523 and a sleeve 524 so that the friction pad 521 rotates in conjunction with the rotating drums 210 and 220. The rotary plate 523 is coupled to the first and second rotary drums 210 and 220 so as to integrally rotate with the first and second rotary drums 210 and 220, respectively, and a gear tooth is formed on the outer peripheral surface. The sleeve 524 is coupled to the rotation shaft 521-1 of the friction pad 521 and has a gear tooth formed on the outer circumferential surface thereof so as to be engaged with the gear tooth of the rotation plate 523 and rotates in conjunction with the rotation plate 523. A separate one-way bearing 525 is provided between the rotary shaft 521-1 of the friction pad 521 and the sleeve 524 so that the friction pad 521 and the sleeve 524 rotate integrally with each other only in one direction. Can be inserted and coupled. At this time, the one-way bearing 525 is engaged with the friction pad 521 and the sleeve 524 in the section where the first and second rotary drums 210 and 220 are pulled and rotated by the pulling of the first and second operation cables 310 and 320, Are integrally rotated.

The pressing body 522 includes a head portion 522-1 having a gear tooth formed on an outer circumferential surface thereof to be rotated by the operation force transmitting means 530 and having one side contacting the friction pad, And a rotary shaft rod 522-2 which is elongated at the center of one surface of the case body 522-1 and has a thread S formed on the outer circumferential surface thereof and is screwed to the case 100. The head portion 522-1 and the rotary shaft rod The contact force of the head portion 522-1 with respect to the friction pad 521 is adjusted.

6, when the pressing body 522 is rotated in one direction, the pressing body 522 is rotated by the thread S of the rotating shaft rod 522-2, As shown in Fig. When the pressing body 522 moves to the right side, one surface of the head portion 522-1 of the pressing body 522 comes into stronger contact with one surface of the friction pad 521, so that mutual contact force is strengthened.

Meanwhile, the friction pad 521 rotates integrally with the rotary drums 210 and 220 by the rotary plate 523, the sleeve 524 and the one-way bearing 525. At this time, the operation structure of the one-way bearing 525 The friction pads 521 rotate integrally with the rotary drums 210 and 220 during the traction rotation of the rotary drums 210 and 220 (the sections where the operation cables 310 and 320 are pulled), but when the rotary drums 210 and 220 are pulled- Only the rotating plate 523 and the sleeve 524 are integrally rotated with the rotating drums 210 and 220 while the friction pad 521 is rotated integrally with the one way bearing 525 by the one- And maintains the stationary state. That is, only the rotating plate 523 and the sleeve 524 are rotated by the one-way bearing 525.

According to this structure, when the pressing body 522 is finely moved close to the friction pad 521 and the contact force between the pressing body 522 and the friction pad 521 is strengthened, the pressing force of the pressing body 522 and the friction pad 521 The rotational resistance against the friction pad 521 is increased so that a relatively larger traction force is generated in the course of pulling the actuating cables 310 and 320 and pulling the rotary drums 210 and 220 Is required. Conversely, when the contact force between the pressing body 522 and the friction pad 521 is weakened by finely moving the pressing body 522 away from the friction pad 521, the contact force between the pressing body 522 and the friction pad 521 The rotational resistance with respect to the friction pad 521 is reduced and therefore a relatively smaller traction force is sufficient to pull the actuating cables 310 and 320 to pull the rotary drums 210 and 220.

As described above, when the one-way bearing 525 is inserted between the rotary shaft 522-1 of the friction pad 521 and the sleeve 524, the frictional pad 521 Only the rotating plate 523 and the sleeve 524 rotate integrally with the rotating drums 210 and 22 by the one-way bearing 525 in a stationary state. Therefore, no friction force is generated between the friction pad 521 and the pressing body 522 because rotation of the friction pad 521 does not occur when the rotary drums 210 and 220 are pulled off, 210 and 220 are elastically rotated by the elastic rotation restoring force of the elastic members 410 and 420 in a state in which no separate rotational resistance is applied regardless of the strength adjusting step by the strength adjusting means 520a and 520b . Therefore, more smooth and stable operation is possible.

The operation force transmitting means 530 includes an internal gear 531 coupled to the operation knob 510 and integrally rotated with the operation knob 510 to form a gear tooth on the inner peripheral surface thereof, A connecting gear 532 having a gear tooth formed on its outer circumferential surface so as to engage with the connecting gear 532 and rotating in conjunction with the internal gear 531 and a connecting gear 532 coupled to the connecting gear 532 so as to rotate integrally with the connecting gear 532, And a driving gear 533 having gear teeth formed on the outer circumferential surface thereof so as to simultaneously engage with gear teeth of the head portion 522-1 formed on each of the pressing bodies 522 of the driving force adjusting means 520a and 520b .

7, the internal gear 531 rotates, and the connection gear 532 and the connecting gear 532, which are engaged with the internal gear 531, are rotated by the rotation of the operation knob 510 The driving gear 533 to be coupled rotates integrally. The driving gear 533 is engaged with the gear teeth of the head portion 522-1 of the pressing body 522. When the driving gear 533 rotates, the pressing body 522 rotates, and the pressing body 522 rotates And is linearly moved by the thread S. The contact strength with the friction pad 521 is changed in accordance with the linear movement of the pressing body 522 so that the strength of the traction force required for the traction rotation with respect to the rotary drums 210 and 220 is adjusted.

Meanwhile, as shown in FIG. 8, strength display members 150, which are different from each other, may be detachably coupled to the front surface of the case 100 in accordance with the strength adjusting step of the strength adjusting module 500.

The intensity indicating member 150 may be formed to have different patterns 152 so as to have a color, a pattern, a number, etc. corresponding to the intensity adjusting step. For example, in a case where the intensity adjusting step is one step A red color is printed and displayed on the pattern portion 152 corresponding to the case where the intensity is controlled in the second step, and in the case where the intensity adjusting step is performed in the third step, Can be printed and displayed on the pattern unit 152.

By coupling the strength indicator 150 to the front surface of the case 100 in a detachable manner, the intensity control step of the user can be recognized externally, so that the user can enjoy the excitement through comparison with other users.

In addition, the strength indicator 150 may be configured to rotationally restrain the operating state of the operation knob 510 to a position corresponding to the intensity adjustment stage in a state where the intensity indicator 150 is coupled to the front surface of the case 100. That is, when the two-stage strength indicator 150 is coupled to the case 100, the operation of the operation knob 510 can be limited to one stage or two stages and can not be performed in three stages .

A separate stopper projection 171 may be provided on one side of the strength indicator 150 for rotation restraining function of the intensity indicator 150 with respect to the operation knob 510. The stopper projection 171 may be provided with a strength indicator Or may be integrally formed on the member 150, but may be separately formed on a separate finishing cover 170 as shown in FIG. At this time, the position of the stopper protrusion 171 and the like of the finishing cover 170 should be different from each other corresponding to the strength adjusting step.

A different identification member 641 is mounted on the intensity display member 150 for each type and an intensity display member detection sensor 641 for detecting the recognition member 641 is provided in the inner space of the case 100 642 can be mounted. Thus, it is possible to determine how many levels of the intensity adjustment step are applied to the device, and information on the intensity adjustment step can be transmitted to the external terminal through a separate communication unit.

The LED lamp may be mounted on the front surface of the case 100 so as to emit light by a separate light emitting lamp 160. For example, a plurality of LED lamps may be mounted on the PCB P in the circumferential direction Lt; / RTI > At this time, a diffusing lens 161 may be coupled to the front surface of the case 100 to diffuse the light of the light emitting lamp 160 and emit light toward the front of the case 100.
