The leg length adjustment unit 610 may include a detent link 730. The detent link 730 may rotate about the rotation axis 7310. When one end of the detent link 730 contacts the ratchet gear 721, the moving gear unit 720 may be rotatable only in the first direction. Here, the fact that one end of the detent link 730 contacts the ratchet gear 721 may mean that one end of the detent link 730 engages or meshes with the ratchet gear 721. That the moving gear unit 720 can rotate only in the first direction may mean that the leg massage unit 2300 can only move in a direction away from the body massage unit 2100. That is, when the user pushes the leg massage unit 2300 with his or her foot, the leg massage unit 2300 may move away from the body massage unit 2100. Additionally, if the user does not push the leg massage unit 2300 with his or her feet, the leg massage unit 2300 may not move away from the body massage unit 2100.

Additionally, when one end of the detent link 730 does not contact the ratchet gear 721, the moving gear unit 720 may be rotatable in the first direction or the second direction. Here, the first direction may be different from the second direction. For example, if the first direction is clockwise, the second direction may be counterclockwise. Additionally, when the first direction is counterclockwise, the first direction may be clockwise.

The leg length adjustment unit 610 may include an action link 740 for connecting the detent link 730 and the vertical bar 750. The motion link 740 may cause the detent link 730 to rotate clockwise or counterclockwise based on the movement of the vertical moving bar 750. The operating link 740 may cause one end of the detent link 730 to contact or separate from the ratchet gear 721 based on the movement of the vertical moving bar 750.

The leg length adjustment unit 610 may include a vertical bar (750). The floating rod 750 is coupled to the motion link 740 and may extend to the ground contact wheel 760.

The leg length adjustment unit 610 may include a ground contact wheel 760. The ground contact wheel 760 may be coupled to the Shanghai Dongbong (750). When the ground contact wheel 760 receives force from the ground, the ground contact wheel 760 applies force to the vertical bar 750 so that the vertical bar 750 moves relative to the leg length adjustment unit housing 770. You can. Here, the fact that the ground contact wheel 760 receives force from the ground indicates that the ground contact wheel 760 has touched the ground.

To be more specific, when the ground contact wheel 760 is in the air and touches the ground, the ground contact wheel 760 may be stopped by the ground. In addition, the Shanghai Dongbong (750) fixed to the ground contact wheel (760) can also be stopped. However, the leg length adjustment unit housing 770 is not fixed to the Shanghai Dongbong (750). Therefore, the leg length adjustment unit housing 770 can move toward the ground contact wheel 760 by external force or inertia. The movement of the leg length adjustment unit housing 770 may be equivalent to the movement of the Shanghai Dongbong 750 relative to the leg length adjustment unit housing 770. The direction in which the Shanghai Dongbong (750) moves relative to the leg length adjustment unit housing (770) may be opposite to the direction (765).

The leg length adjustment unit 610 may include a vertical spring 780. The vertical bar spring 780 is configured to push the vertical vertical bar 750 in the direction of the ground contact wheel 760 so that the ground contact wheel 760 can contact the floor. In addition, the vertical spring 780 can maintain the detent link in contact with the ratchet gear when the ground contact wheel 760 does not receive force from the floor.

The Shanghai Dongbong spring 780 can be compressed when the ground contact wheel 760 receives force from the ground. Additionally, when the vertical bar spring 780 is compressed, force can be applied to the vertical vertical bar 750 in the direction 765 of the ground contact wheel 760. The vertical bar spring 780 can cause the vertical vertical bar 750 to return to its original position when the ground contact wheel 760 does not receive force from the ground. The original location of the Shanghai East Peak (750) may be as shown on the right side of FIG. 7. In addition, when the force received from the ground by the ground contact wheel 760 is greater than the force applied by the vertical bar spring 780 to the vertical vertical bar 750, the vertical vertical bar 750 moves relative to the leg length adjustment unit housing 770. You can move.

When the ground contact wheel 760 does not receive force from the ground, one end of the detent link 730 is in contact with the ratchet gear 721 due to the force applied by the vertical bar spring 780 to the vertical bar 750. can be maintained. At this time, the moving gear unit 720 may be rotatable only in the first direction. Here, the first direction may be either clockwise or counterclockwise. Additionally, when the user pushes the leg massage unit 2300, the moving gear unit 720 rotates in the first direction, so that the leg massage unit 2300 moves away from the body massage unit 2100. Additionally, when the user does not push the leg massage unit 2300, the leg massage unit 2300 receives force to return to its original state by the restoration spring, but the moving gear unit 720 moves in a second direction different from the first direction. Since it cannot rotate, the leg massage unit 2300 may not get close to the body massage unit 2100. That is, the current position of the leg massage unit 2300 with respect to the body massage unit 2100 can be maintained.

When the ground contact wheel 760 receives force from the ground, one end of the detent link 730 does not contact the ratchet gear 721, and the moving gear unit 720 rotates in the first and second directions. You can. The first direction and the second direction represent different directions.

When the user applies force to the leg massage unit 2300 while the ground contact wheel 760 receives force from the ground, the leg massage unit 2300 may move along the leg length adjustment unit 610. However, when the user removes the force applied to the leg massage unit 2300 while the ground contact wheel 760 receives force from the ground, the leg massage unit 2300 moves along the leg length adjustment unit based on the restoration spring. It can be restored to its original state. The restoration spring may apply force to the leg massage unit 2300 so that the leg massage unit 2300 returns to its original state. Additionally, since the moving gear unit 720 can rotate in both the first and second directions, the leg massage unit 2300 can return to its original state by the force of the restoration spring. Returning to the original state may mean that the leg massage unit 2300 becomes closer to the body massage unit 2100, as shown in the left picture of FIG. 9.

Figure 8 is a diagram for explaining a leg length adjustment unit according to an embodiment of the present disclosure. Additionally, Figure 9 is a diagram for explaining a leg length adjustment unit according to an embodiment of the present disclosure.

Referring to the above picture 810 of FIG. 8, the angle adjustment rack gear 710 can rotate with one end 820 connected to the body massage unit 2100 as a rotation axis.

The ground contact wheel 760 may not receive force from the ground. In the present disclosure, the fact that the ground contact wheel 760 does not receive force from the ground may indicate that the ground contact wheel 760 is away from the ground.

Briefly referring to FIG. 9 , picture 910 may represent the original state of the leg massage unit 2300. When the body massage unit 2100 is laid down as shown in Figure 950, the leg massage unit 2300 may move away from the ground. Additionally, the ground contact wheel 760 may also fall off the ground.

Referring again to the above figure 810 of FIG. 8, when the leg massage unit 2300 rotates one end 820 as the rotation axis so that the leg massage unit 2300 opens from the body massage unit 2100, the ground contact wheel ( 760) may fall to the ground.

As explained in FIG. 7, when the ground contact wheel 760 does not receive force from the ground, one end of the detent link 730 contacts the ratchet gear 721, and the moving gear unit 720 moves in the first direction. Only rotation is possible. Here, the first direction may be either clockwise or counterclockwise. Additionally, when the user pushes the leg massage unit 2300, the moving gear unit 720 rotates in the first direction, so that the leg massage unit 2300 moves away from the body massage unit 2100. Additionally, when the user does not push the leg massage unit 2300, the leg massage unit 2300 receives force to return to its original state by the restoration spring, but the moving gear unit 720 moves in a second direction different from the first direction. Since it cannot rotate, the leg massage unit 2300 may not get close to the body massage unit 2100. That is, the current position of the leg massage unit 2300 with respect to the body massage unit 2100 can be maintained.

Referring to the figure 850 below in FIG. 8 , when the user applies force to the leg massage unit 2300, the leg massage unit 2300 may move along the leg length adjustment unit 610. Additionally, after the leg massage unit 2300 moves, the position of the leg massage unit 2300 with respect to the leg length adjustment unit 610 can be maintained even without the user applying force to the leg massage unit 2300. That is, even if the user does not apply force to the leg massage unit 2300, the position of the leg massage unit 2300 may not move away from or closer to the body massage unit 2100 with respect to the leg length adjustment unit 610. The reason why the position of the leg massage unit 2300 is maintained even if the user does not apply force to the leg massage unit 2300 is because one end of the detent link 730 is in contact with the ratchet gear 721, and the moving gear unit 720 This is because it can only rotate in the first direction.

Figure 10 is a diagram for explaining a leg length adjustment unit according to an embodiment of the present disclosure.

Referring to the above picture 1010 of FIG. 10, the ground contact wheel 760 can receive force from the ground. In the present disclosure, the fact that the ground contact wheel 760 receives force from the ground may indicate that the ground contact wheel 760 is in contact with the ground. As described in FIG. 7, when the ground contact wheel 760 receives force from the ground, one end of the detent link 730 does not contact the ratchet gear 721, and the moving gear unit 720 moves in the first direction. and can rotate in a second direction. The first direction and the second direction represent different directions. For example, if the first direction is clockwise, the second direction is counterclockwise, and if the first direction is counterclockwise, the second direction is clockwise.

When the user applies force to the leg massage unit 2300 while the ground contact wheel 760 receives force from the ground, the leg massage unit 2300 may move along the leg length adjustment unit 610. This may be the same as Figure 8.

However, when the user removes the force applied to the leg massage unit 2300 while the ground contact wheel 760 receives force from the ground, the leg massage unit 2300 moves along the leg length adjustment unit based on the restoration spring. It can be restored to its original state. The restoration spring may apply force to the leg massage unit 2300 so that the leg massage unit 2300 returns to its original state. Additionally, since the moving gear unit 720 can rotate in both the first and second directions, the leg massage unit 2300 can return to its original state by the force of the restoration spring.

The original state is the basic state of the leg massage unit 2300. The original state may represent a state in which the leg length adjusting unit 610 is at its shortest. Additionally, the original state may represent a state such as figure 910 of FIG. 9. The lower picture 1050 of FIG. 10 shows the process of the leg massage unit 2300 returning to its default state.

Figure 11 is a diagram for explaining a leg length adjustment unit according to an embodiment of the present disclosure.

When the ground contact wheel 760 does not receive force from the ground, the vertical moving bar 750 may be in the original position. The original position of the Shanghai East Peak 750 may be the same as the left drawing of FIG. 11. The lowering rod spring 780 may apply force to the lowering rod (750) so that the lowering rod (750) can remain in its original position.

When the vertical movement bar 750 is in the original position, one end 731 of the detent link 730 may be engaged with the ratchet gear 721 by the operation link 740 connected to the vertical movement bar 750. As shown in FIG. 11, the ratchet gear 721 may have an inclined sawtooth shape. Additionally, one end 731 of the detent link 730 close to the ratchet gear 721 may have a bent shape.

When one end 731 of the detent link 730 is engaged with the ratchet gear 721, the moving gear unit 720 can rotate only in the first direction 1111. When one end 731 of the detent link 730 is engaged with the ratchet gear 721, it may not be mechanically possible for the moving gear unit 720 to rotate in the second direction 1112.

Figure 12 is a diagram for explaining the operation of the leg adjuster according to an embodiment of the present disclosure.

Illustration 1210 of FIG. 12 shows a case where the ground contact wheel 760 does not receive force from the ground. Referring to the picture 1250 of FIG. 12, when the ground contact wheel 760 does not receive force from the ground, the vertical bar 750 can receive force in the direction 1260 by the vertical vertical bar spring 780. . Shanghai East Peak (750) can maintain its original position. At this time, when the user applies force to the leg massage unit 2300, the pinion gear 722 included in the moving gear unit 720 engages with the angle adjustment rack gear 710 and rotates in the first direction 1111. You can. Additionally, the leg massage unit 2300 can move along the angle adjustment rack gear of the leg length adjustment unit 610. The leg massage unit 2300 may be moved away from the body massage unit 2100 from its original state.

In addition, when the ground contact wheel 760 does not receive force from the ground and the user does not apply force to the leg massage unit 2300, the moving gear unit 720 is connected to the ratchet gear 721 and the ratchet gear 721. Rotation can be prevented by the engaged detent link 730. As already described, the restoration spring may be applying force to the leg massage unit 2300 in a direction to return it to its original state. However, since the movable gear unit 720 cannot rotate in the second direction due to the ratchet gear 721 and the detent link 730, the leg massage unit 2300 may not return to its original state. That is, the leg massage unit 2300 can maintain the current position with respect to the angle adjustment rack gear of the leg length adjustment unit 610.

Figure 13 is a diagram for explaining the operation of the leg adjuster according to an embodiment of the present disclosure.

Figure 1310 in FIG. 13 shows a case where the ground contact wheel 760 receives force from the ground. Referring to the picture 1350 of FIG. 13, when the ground contact wheel 760 receives force from the ground, the Shanghai Dongbong 750 moves in the opposite direction of the ground contact wheel with respect to the leg length adjustment unit housing 770 ( 1360). As already described, when the force received by the ground contact wheel 760 from the ground is greater than the vertical bar spring 780, the vertical vertical bar 750 may move relative to the leg length adjustment unit housing 770.

When the vertical bar (750) moves in the direction opposite to the direction of the ground contact wheel (1360) with respect to the leg length adjustment unit housing (770), the detent link (740) is connected to the vertical vertical bar (750). One end 731 of 730 may not engage with the ratchet gear 721. At this time, the moving gear unit 720 can rotate in both directions (1111, 1112).

When the ground contact wheel 760 receives force from the ground and the user does not apply force for leg massage, the moving gear unit 720 moves in the second direction opposite to the first direction 1111 based on the force applied by the restoration spring. It can rotate in direction 1112. As already described, the restoration spring may apply force to return the leg massage unit 2300 to its original state. At this time, the leg massage unit 2300 can be restored to its original state along the angle adjustment rack gear 710 of the leg length adjustment unit 610.

Figure 14 shows a massage device according to an embodiment of the present disclosure.

Pictures 1410 and 1450 of FIG. 14 may represent a case where the body massage unit 2100 is not laid down. Referring to FIG. 14, the angle adjustment rack gear 710 can be unfolded or folded by an angle adjustment actuator. One end 820 of the angle adjustment rack gear 710 may be fixed to the body massage unit 2100. The angle-adjustable rack gear 710 may rotate with respect to one end 820 of the angle-adjustable rack gear 710 based on the angle-adjustable actuator.

For example, picture 1410 of FIG. 14 shows the angle adjustment rack gear 710 in a folded state. Additionally, figure 1410 shows the original state of the leg massage unit 2300.

Additionally, picture 1450 of FIG. 14 shows the angle-adjustable rack gear 710 in an unfolded state. The angle adjustment actuator can fold or unfold the angle adjustment rack gear 710 based on a control signal from the control unit 300. Figure 1450 may not represent the angle-adjustable rack gear 710 in its fully expanded state. Figure 1450 may be in a state where the angle-adjustable rack gear 710 is fully expanded so that the ground contact wheel 760 is in contact with the ground. The massage device 100 can expand the angle adjustment rack gear 710 beyond the angle shown in figure 1450.

When the angle-adjusting rack gear 710 is folded as shown in figure 1410 of FIG. 14, the angle between the vertical pole 750 and the direction perpendicular to the ground 1420 may be the first angle 1430. In addition, when the angle-adjustable rack gear 710 is unfolded as shown in the picture 1450 of FIG. 14, the angle between the vertical pole 750 and the direction perpendicular to the ground 1420 may be the second angle 1470. In addition, the first angle 1430 or the second angle 1470 may refer to the angle formed between the vertical bar 750 and the direction perpendicular to the ground 1420 when the ground contact wheel 760 is in contact with the ground. there is. That is, when the ground contact wheel 760 is not in contact with the ground, the angle formed between the vertical bar 750 and the direction perpendicular to the ground 1420 may not be the first angle 1430 or the second angle 1470. there is.

Mechanically, the first angle 1430 and the second angle 1470 may be the same. Additionally, the control unit 300 of the massage device 100 may control the first angle 1430 and the second angle 1470 to be equal. For example, the controller 300 may control the second angle 1470 to be identical to the predetermined first angle 1430.

The second angle may be the angle between the vertical bar 750 and the direction 1420 perpendicular to the ground when the angle adjustment rack gear 710 is fully expanded so that the ground contact wheel 760 is in contact with the ground. The control unit 300 may prevent the second angle 1470 from being larger than the first angle 1430. When the second angle 1470 becomes larger than the first angle 1430 while unfolding the angle adjustment rack gear 710, the control unit 300 lays the body massage unit 2100 back so that the ground contact wheel 760 is off the ground. You can control it to fall. Accordingly, the control unit 300 can prevent the ground contact wheel 760 from receiving force from the ground when the second angle 1470 is greater than the first angle 1430.

The control unit 300 may measure the first angle 1430 or the second angle 1470 based on the angle sensing unit of the vertical moving bar 750. The control unit 300 may know the location of the reference line in advance. The baseline may be in the same direction as gravity (perpendicular to the ground). The angle sensing unit may transmit information about the angle at which the vertical pole 750 deviates from the baseline to the control unit 300. The controller 300 may obtain the first angle 1430 or the second angle 1470 based on angle information.

The control unit 300 may receive a signal from an acceleration sensor to measure the first angle 1730 or the second angle 1470. An acceleration sensor can measure the direction of gravity. Since the direction of gravity is perpendicular to the ground, the control unit 300 can obtain the reference line based on the acceleration sensor.

In this way, by maintaining the sizes of the first angle 1430 and the second angle 1470 the same, the durability of the massage device 100 can be increased. For example, by keeping the sizes of the first angle 1430 and the second angle 1470 the same, deformation of the vertical bar 750 can be minimized.

Figure 15 is a diagram showing a massage device according to an embodiment of the present disclosure.

The leg massage unit 2300 of the massage device 100 may further include an unlocking footrest 1510 connected to the leg length adjustment unit 610. The unlocking step 1510 may be connected to the Shanghai East Peak (750). The unlocking step 1510 can move the vertical bar 750 toward the ground contact wheel 760 or move it to the opposite side of the ground contact wheel 760 based on the user's operation. Hereinafter, the configuration of the fund release platform 1510 will be described in more detail with reference to FIG. 15.

Figure 16 is a diagram showing an unlocking step according to an embodiment of the present disclosure.

The unlocking pedal 1510 may include a pedal operation link 1620. One end of the pedal operation link 1620 may be connected to the other end of the Shanghai Dongbong hinge link 1610. A second link shaft 1612 may be used to connect one end of the pedal operation link 1620 and the other end of the vertical hinge link 1610.

The pedal operation link 1620 may include a pedal fixing hinge 1625. The pedal operation link 1620 may be connected to the leg massage unit 2300 by the pedal fixing hinge 1625. The pedal operation link 1620 can perform a seesaw movement based on the pedal fixing hinge 1625.

Figure 17 is a diagram for explaining an unlocking step according to an embodiment of the present disclosure.

Referring to the above picture 1700 of FIG. 17, as already described, the vertical bar 750 may be receiving force in the direction 1710 of the ground contact wheel 760 by the vertical vertical bar spring 780. In addition, the detent link 730 can be in contact with the ratchet gear 721 by the vertical spring 780. At this time, the moving gear unit 720 can rotate only in the first direction. When the user pushes the leg massage unit 2300, the leg massage unit 2300 may move away from the body massage unit 2100 along the leg length adjustment unit 610. The movement direction of the leg massage unit 2300 may be from the user's legs to the feet. In addition, when the user does not push the leg massage unit 2300, the leg massage unit 2300 receives force to return to its original state by the restoration spring, but the moving gear unit 720 cannot rotate in the second direction, so the leg massage unit 2300 The massage unit 2300 may not get close to the body massage unit 2100. That is, the current position of the leg massage unit 2300 with respect to the body massage unit 2100 can be maintained. The positions of the Shanghai Dongbong hinge link 1610 and the pedal operation link 1620 connected to the Shanghai Dongbong 750 may be as shown in Figure 1700.

Referring to the picture 1750 below in FIG. 17, the user can apply force to the pedal operation link 1620. The force applied by the user to the pedal operation link 1620 may be the same as the direction 1760. The pedal operation link 1620 can rotate around the pedal fixing hinge 1625 by the applied force. The other end of the pedal operation link 1620, toward the user's toes, can descend. In addition, one end of the pedal operation link 1620 can rise together with the Shanghai-dong peak hinge link 1610. Accordingly, the Shanghai East Peak (750) can also move in the opposite direction (1770) of the ground contact wheel (760). As already described, when the Shanghai Dongbong 750 moves in the opposite direction 1770 of the ground contact wheel 760, the detent link 730 may not be in contact with the ratchet gear 721. At this time, the moving gear unit 720 may rotate in both the first direction and the second direction.

The direction of one end of the pedal operation link 1620 may indicate the front direction of the massage device 100. Additionally, the direction of the other end of the pedal operation link 1620 may indicate the rear direction of the massage device 100. According to the principle of the lever, even if the user presses the part in one direction of the pedal operation link 1620 with a small force, the part in the direction of the other end of the pedal operation link 1620 can transmit a large force to the vertical hinge link 1610.

When the user applies force to the pedal operation link 1620 in the direction 1760 and the user also applies force to the leg massage unit 2300, the leg massage unit 2300 moves along the leg length adjustment unit 610. You can move. In addition, when the user removes the force applied to the leg massage unit 2300 while the user is applying force to the pedal operation link 1620 in the direction 1760, the leg massage unit 2300 is based on a restoration spring. Thus, it can be restored to its original state along the leg length adjustment section. Here, the movement direction of the leg massage unit 2300 may be from the user's feet to the legs.

If the user removes the force applied to the pedal operation link 1620, it can return to the same state as shown in the above picture 1700 of FIG. 17.
