使用時(請參閱第六至八圖所示)，藉轉動控制桿(36)帶動旋轉體(34)旋轉，使旋轉體(34)底部延伸凸緣(343)對應於承接片(33)之高斜面(330)頂端，且旋轉體(34)以其第二凸耳(341)對應於限位桿(37)，並受限位桿(37)限制其旋轉位置時，連桿(30)受承接片(33)下壓，使其底端所設之卡止件(45)進入上定位片(46)一側所設方孔(460)內，而使腳輪(1)處於無法轉向，僅可直線位移之定向狀態；當轉動控制桿(36)使旋轉體(34)下部延伸凸緣(343)對應於承接片(33)之低斜面(331)，且旋轉體(34)以其第一凸耳(340)對應於限位桿(37)，並受限位桿(37)限制其旋轉位置時，連桿(30)因第一彈性元件(35)之回復作用上移，帶動其底端所設T型襯套(43)上移，則T型襯套(43)之頂面會將鎖固件(41)往上頂，而使鎖固件(41)之圓柱(410)頂面之卡槽(415)與齒盤(42)之鋸齒(420)相卡合，於此同時，因鎖固件(41)之ㄩ型體(411)上移，使軸心套(9)及軸心(10)落於ㄩ型體(411)所設橢圓孔(416)之下端，而ㄩ型體(411)兩側之水平條齒(417)則因上移而分別與左、右側滾輪(5)、(5a)內側之卡槽(51)相卡合，而使腳輪(1)之旋轉及滾動動作同步煞止；而當鎖固件(41)之圓柱(410)頂面之卡槽(415)以及ㄩ型體(411)兩側之水平條齒(417)在進行卡合動作時，可藉第三彈性元件(44)之彈力進行卡合緩衝，使鎖固件(41)圓柱(410)之卡槽(415)順利的與齒盤(42)之鋸齒(420)卡合，而ㄩ型體(411)之水平條齒(417)亦順利的與左、右側滾輪(5)、(5a)之卡槽(51)相卡合。When in use (please refer to the sixth to eighth figures), the rotating body (34) is rotated by the rotating control lever (36), so that the bottom extending flange (343) of the rotating body (34) corresponds to the receiving piece (33). The top of the high slope (330), and the rotating body (34) corresponding to the limiting rod (37) with the second lug (341) and the limiting position (37) restricting its rotational position, the connecting rod (30) Pressed by the receiving piece (33), the locking member (45) provided at the bottom end thereof is inserted into the square hole (460) provided on the side of the upper positioning piece (46), so that the caster (1) is unable to turn, Only the orientation state of the linear displacement; when the rotation control lever (36) causes the lower extension flange (343) of the rotating body (34) to correspond to the low slope (331) of the receiving piece (33), and the rotating body (34) The first lug (340) corresponds to the limiting rod (37), and when the restricted position rod (37) limits its rotational position, the connecting rod (30) is moved up by the return action of the first elastic element (35). The T-shaped bushing (43) provided at the bottom end is moved up, and the top surface of the T-shaped bushing (43) will push the lock (41) upward, and the top of the cylinder (410) of the lock (41) The card slot (415) of the face is engaged with the serration (420) of the toothed disc (42), and at the same time, due to the jaw body (411) of the locker (41) The shaft sleeve (9) and the shaft center (10) are placed at the lower end of the elliptical hole (416) provided in the ㄩ body (411), and the horizontal teeth (417) on both sides of the ㄩ body (411) are caused by Upwardly engaging with the card slots (51) on the inner side of the left and right rollers (5), (5a), respectively, and rotating and rolling the casters (1) synchronously; and when the locks (41) The card slot (415) on the top surface of the cylinder (410) and the horizontal strip teeth (417) on both sides of the ㄩ-shaped body (411) can be engaged and buffered by the elastic force of the third elastic member (44) when the engaging action is performed. The card slot (415) of the cylinder (410) of the locking member (41) smoothly engages with the serration (420) of the toothed disc (42), and the horizontal teeth (417) of the jaw body (411) are also smooth. It is engaged with the card slots (51) of the left and right rollers (5) and (5a).
當旋轉控制桿(36)帶動旋轉體(34)使其底部延伸凸緣(343)對應於承接片(33)之弧凹(332)時，(請參閱第五圖所示)，限位桿(37)位於旋轉體(34)之第一、第二凸耳(340)、(341)之間，連桿(30)受承接片(33)下壓適度距離，帶動其底端所套設T型襯套(43)下移而不再頂住鎖固件(41)，則鎖固件(41)可因其ㄩ型體(411)內部所設第二彈性元件(40)之回復力而順利回復原位，使其圓柱(410)之卡槽(415)不再與齒盤(42)之鋸齒(420)卡合，而水平條齒(417)亦不再與左、右側滾輪(5)、(5a)之卡槽(51)相卡合，同時，卡止件(45)亦未落於上定位片(46)之方孔(460)內，則腳輪(1)處於可旋轉及滾動之無煞車狀態，此時，軸心套(9)及軸心(10)亦回復至鎖固件(41)之ㄩ型體(411)所設橢圓孔(416)之上端。When the rotary lever (36) drives the rotary body (34) such that the bottom extension flange (343) corresponds to the arc recess (332) of the receiving piece (33) (refer to the fifth figure), the limit lever (37) is located between the first and second lugs (340) and (341) of the rotating body (34), and the connecting rod (30) is pressed by the receiving piece (33) by a moderate distance to drive the bottom end thereof. When the T-shaped bushing (43) is moved down and no longer resists the locking member (41), the locking member (41) can be smoothly recovered by the restoring force of the second elastic member (40) provided inside the ㄩ-shaped body (411). Returning to the original position, the slot (415) of the cylinder (410) is no longer engaged with the serrations (420) of the chainring (42), and the horizontal teeth (417) are no longer associated with the left and right rollers (5) The card slot (51) of (5a) is engaged with each other, and at the same time, the locking member (45) does not fall within the square hole (460) of the upper positioning piece (46), and the caster (1) is rotatable and rolling. In the state of no brake, at this time, the shaft sleeve (9) and the shaft center (10) also return to the upper end of the elliptical hole (416) provided in the jaw body (411) of the locker (41).
