Reference numeral 900 not shown is a power cord.

On the other hand, the chair A applied to the present invention is for office use, but is not limited to office use.

Referring to the operation of the chair type waist motion mechanism according to the first embodiment of the present invention having the above structure as follows.

First, the user plugs the power cord 900 into an outlet (not shown), and then raises and lowers the support member 200 to fit the user's physical condition. That is, the driving unit 610 is driven by operating a switch on a control panel (not shown). When the elevating drive motor 610 is driven, the driving force of the elevating drive motor 610 is fixed to the bottom edge of the base plate 210 via the elevating drive sprocket 620 and the elevating drive chain 670. The elevating driven sprocket 660 coupled to the elevating bearing 650 coupled to the elevating fixing unit 640 is driven.

When the elevating driven sprocket 660 is driven, the elevating driven sprocket 660 coupled to the elevating bearing 650 and screwed with the spiral supporting shaft 630 rotates along the spiral supporting shaft 630. The support member 200 is repeatedly moved downward to operate up and down as shown in FIG. 5B in the state shown in FIG. 5A.

Subsequently, when the support member 200 is positioned to fit the user's physical condition, the user operates the angle actuator 500 to operate the member 100 and the chair adjusting member 300 such that the link 330 is inclined at an angle. ) To adjust. That is, the angle driving motor 510 is driven by operating a switch on the control panel. When the angular drive motor 510 is driven, the driving force of the angular drive motor 510 is fixed to the central portion of the bottom surface of the base plate 210 through the angular drive sprocket 520 and the angular drive chain 560. It drives the angular driven sprocket 550 coupled to the angular bearing 540 is coupled to.

When the angular driven sprocket 550 is driven, the angular driven sprocket 550 which is coupled to the angular bearing 540 and screwed to the threaded portion 127 formed at the outer circumferential bottom of the vertical end 126 of the operating shaft 120 is operated. Continued rotation along the vertical end 126 of the shaft 120, the vertical end 126 screwed with the angular driven sprocket 550 is moved up and down by the rotation of the angular driven sprocket 550, the vertical The chair support shaft 110 is also moved by the movement of the end 126. 6B is a state in which the upper link 331 fixed to the upper fixture 310 fixed to the chair support shaft 110 is fixed to the chair support shaft 110 by the upward movement of the chair support shaft 110. It is inclined as follows. Here, the chair support shaft 110 is formed to be inclined in the direction of the link link 333 by the inclination (approximately 10 to 20 °) of the upper link 331, the second control pin where the link link 333 is located 142 protrudes upward through the auxiliary operation groove 115, as shown in Figure 9a.

At this time, stopping the operation of the angle operating port 500 prevents the vertical end 126 of the operating shaft 120 screwed to the angle driven sprocket 550 coupled to the angle fixing portion 530 is separated. do. Then, when the operating member 100 is moved downward by the angle operating port 500, the contact end 710 of the sensing member 700 is moved along the lower direction while being guided along the operating hole 221, the operating hole While moving along 221, when the contact end 710 contacts the detection sensor 720 installed at the lower end of the operation hole 221, the control unit 730 receives a signal from the detection sensor 720 to operate the angle operation port ( Stop the operation of 500). At this time, to stop the operation of the angular operating port 500 is the upper link 331 is a lower link when the vertical end 126 of the operating shaft 120 screwed to the angular driven sprocket 550 continues to move downward This is to prevent the inclination more than a certain angle in the (332) direction.

When the link 330 is formed to be inclined at an angle as described above, the user operates the rotation operation tool 400 to operate the link 330 of the chair adjusting member 300. That is, the rotary drive motor 410 is driven by operating a switch on the control panel. When the rotation drive motor 410 is driven, the driving force of the rotation drive motor 410 drives the rotary driven pulley 430 coupled with the link 330 through the rotation drive belt 440 and eventually the link 330. Rotates.

Subsequently, referring to FIG. 7, when the link 330 is rotated 360 ° with respect to the support member 200 by the rotation of the rotary actuator 400, the chair support shaft 110 is connected to the link 330 of the link 330. The front and rear, left and right along the direction (333) is moved, thereby exercising the user's waist. At this time, the support ball 111 of the chair support shaft 110 is smoothly flowed by the oilless bearing (130).

The present invention as described above can be seen by twisting the waist forward, backward, left, right while maintaining the original chair function, the twisting effect and stretching effect, and can prevent various diseases such as obesity and lumbar disc, such as service obesity .
