The turntable 21 and a seat 22 supported on the turntable 21 (other components of the massage footrest 2 are not related to the present invention, and therefore will not be described again). Below the turntable 21, a related rotating mechanism such as a conventional bearing 24 is disposed so that the turntable 21 can be rotated to rotate the seat 22 together. The manner in which the seat 22 is rotated can be referred to the prior art 'but not limited thereto. The orientation device 3 is mounted on the base 20 and includes a biasing mechanism 4, a stop mechanism 5, an operating lever 6, and the like. The operating lever 6 is exposed to the base φ housing 23 and is optionally disposed on either or both sides of the base housing 23 (as shown in Fig. 2). The operating lever 6 serves to apply an external force 'to cause the biasing mechanism 4 to actuate the blocking mechanism 5' to move the blocking mechanism 5 to a certain position (shown in FIG. 4) or to leave in a non-directional position ( (Fig. 5): wherein, when the stopping mechanism 5 is in the orienting position, the brake shoe piece 517 fixed to the stopping mechanism 5 abuts against the outer side surface of the turntable 21 to fix the turntable 21 and cannot rotate. Thereby the seat 22 is fixed in a fixed direction. In detail, the biasing mechanism 4 ′ includes a base portion 40 , a first factory [5 201206413 crank arm 41 and a second crank arm 42 . The base portion 40 is fixed on the base 20 and located at the turntable 21 . The first curved arm 41 is curved, and a corner protruding toward the turntable 21 is formed in the middle portion, and the first end 410 is pivotally connected to the first end 401 of the base portion 40 to be swingable. The second end 411 extends in the opposite direction of the turntable 21; the second curved arm 42 is curved, the first end 420 is pivotally connected to the middle portion of the first crank arm 41, and the other second end 421 is The blocking mechanism 5 extends in the direction of 0. The first curved arm 41 substantially forms a clamping structure by two identical curved arm pieces, and the second curved arm 42 is pivotally connected to the first end 420 of the φ-curved arm 41. Located between the arm pieces and pivoted to the curved pieces. The above pivoting is accomplished through the pin and the pin hole, and the pivoting as described below will also be accomplished through the pin and the pin hole. Of course, those skilled in the art can use other equal means of the same function instead. In addition, the biasing mechanism 4 further includes a first linkage rod 43 and a second linkage rod 44. The first end 430 of the first linkage rod 43 is pivoted with the second end 411 of the first crank arm 41. The second end 431 extends to the distal end of the base 20 and is pivotally connected to the first end 440 of the second linkage rod 44. The second end 441 of the second linkage rod 44 is fixed to a pivot 61. The pivot shaft 61 is pivoted on a support portion 20' extending from the base 20, and at least one end portion of the pivot shaft 61 extends outside the base shell 23. The operating lever 6 is selectively affixed to an end of one or both ends of the pivot 61 such that the biasing mechanism 4 can bias or release the biasing force by the operating lever 6. The stopping mechanism 5 includes a cylindrical fixing sleeve 50 fixed to the second end 4〇2 of the base portion 40, and a stopping portion 51»moving relative to the fixing sleeve 50. The shaft member 510 includes a shaft member 510 that can be slidably passed through the fixed sleeve 50. The first end 5100 of the shaft member 510 is worn [S1 201206413 through the fixed sleeve 50 to the biasing mechanism 4, and The second end 5101 of the shaft member 510 is pivoted to the second end 421 of the second crank arm 42. The second end 5101 of the shaft member 510 extends over the turntable 21: and is fixedly disposed between the two ends of the shaft member 510. And adjacent to the cartridge 511 of the fixed bushing 50. The cartridge 511 is movable between an orientation position approaching the turntable 21 or a non-directional position away from the turntable 21. The cartridge 511 includes an extending portion 516 extending downward from the bottom thereof and located outside the turntable 21, and a brake shoe 517 fixed to the extending portion 516 for resisting the turntable 21 When the cartridge 511 is biased in the orientated position, the brake shoe 517 abuts against the outer side surface of the turntable 21, so that the turntable 21 is fixed and cannot be rotated, thereby fixing the seat 22 in a fixed direction. Since the shovel shovel 517 is used to abut the turntable 21, the material thereof can be made of a material having a large frictional force, such as a rubber or a sling. In addition, the cartridge 511 is fixed to the shaft member 510 by a fixing member (the nut 52 and the bolt 53), and the second end 5101 of the shaft member 510 is formed with a thread for screwing in a nut 54. The distance between the brake shoe piece 517 and the outer side surface of the turntable 21 is adjusted. # Referring to Fig. 4, in Fig. 4, the stopper mechanism 5 is driven to a directional position by a bias. As shown by the arrow in the figure, when the operator pulls the operating lever 6' downward so that the second linking lever 44 pushes the first linkage lever 43 forward, the first linkage lever 43 activates the first crank arm 41, so that A curved arm 41 pivots forward with its first end 410 as a center, generates a bias during the forward pivoting of the first curved arm 41, pushes the second curved arm 42 forward, and associates the second curved piece The arm 42 pushes the shaft member 510 of the stopping mechanism 5 forward, and the shaft member 510 drives the cartridge 511 forward, so that the braking shoe piece 517 abuts against the outer side surface of the turntable 21, so that the turntable 21 is fixed, thereby fixing the seat 22 - Fixed direction. At this time, [S3 201206413 stop mechanism 5 is driven to the orientation position. Referring again to Figure 5, in Figure 5, the stop mechanism 5 is moved to a non-directional position by a release bias. As shown by the arrow in the figure, when the operator pulls the operating lever 6 upward, the second linkage lever 44 pulls the first linkage lever 43 backward, and the first linkage lever 43 drives the first crank arm 41 to make the first The crank arm 41 pivots rearward about its first end 410, releasing a biasing force to pull the second crank arm 42 during the pivoting of the first crank arm 41, and causing the second crank arm 42 to move backwards. The shaft member 510 of the mechanism 5, the shaft member 510 with the φ moving barrel 511 rearward, causes the brake shoe 517 to move away from the turntable 21, so that the turntable 21 can be freely rotated, so that the seat 22 can be rotated together. At this time, the stopper mechanism 5 is urged to the non-directional position. Therefore, as can be seen from the description of FIGS. 4 and 5, the stopping mechanism 5 can be moved between the directional position or the non-directional position. When the stopping mechanism 5 is in the directional position, the shackle 517 of the stopping mechanism 5 abuts the turntable. 21, the turntable 21 is fixed and cannot be rotated, thereby fixing the seat 22 in a fixed direction. In summary, the orientation device of the massage footrest of the present invention can be easily fixed in the direction of the seat by the movement of the stopper mechanism between the orientation position and the non-orientation position, so that the user can safely and securely Down, it is very convenient to operate. While the invention has been described with respect to the preferred embodiments of the present invention, it is understood that many changes and modifications may be made to those of ordinary skill in the art to which the invention pertains, without departing from the spirit and scope of the invention. . Therefore, the present invention is not limited to the disclosed embodiments, but is intended to be included in the scope of the appended claims. Fan 201206413 Wai.
