參閱圖5及圖8，藉由第二彈簧7對安全鎖5朝鎖定位置方向施加彈力，每一個撥桿55的桿體551後端面會緊抵於對應後端壁23的第二壁部232，而每一個凸板53的豎直面531會緊抵於立板412的第一直立面415，且擋板52的擋止平面521接觸並擋止立板412的底面414。藉此，使得安全鎖5能穩固地定位在鎖定位置。由於立板412的底面414被擋板52的擋止平面521擋止，因此，當操作鈕4的操作殼體42被兒童誤觸下壓時，操作鈕4不會沿第一運動方向D1(如圖11所示)旋轉。藉此，能防止操作鈕4不慎被誤觸時產生轉動並透過纜線12帶動鎖定件解除鎖定狀態，以提升使用上的安全性。 Referring to FIGS. 5 and 8, the second spring 7 applies elastic force to the safety lock 5 in the direction of the locked position, and the rear end surface of the rod body 551 of each shift lever 55 abuts against the second wall portion 232 of the corresponding rear end wall 23 , And the vertical surface 531 of each convex plate 53 abuts against the first vertical surface 415 of the vertical plate 412, and the blocking plane 521 of the baffle 52 contacts and blocks the bottom surface 414 of the vertical plate 412. Thereby, the safety lock 5 can be firmly positioned in the locked position. Since the bottom surface 414 of the vertical plate 412 is blocked by the blocking plane 521 of the baffle 52, when the operating housing 42 of the operating button 4 is accidentally touched and pressed by a child, the operating button 4 will not move along the first movement direction D1 ( As shown in Figure 11) Rotate. Thereby, it is possible to prevent the operation button 4 from turning when accidentally touched by mistake and driving the locking member through the cable 12 to release the locked state, so as to improve the safety in use. Fullness.

此外，藉由每一個撥桿55的桿體551緊抵於對應第二壁部232而被其阻擋，以及每一個凸板53的豎直面531緊抵於第一直立面415而被其阻擋，使得殼體2及操作鈕4能起到阻擋安全鎖5的作用，以防止撥桿55被兒童誤觸下壓而沿第一運動方向D1旋轉，進而導致擋板52的擋止平面521脫離底面414的情形。本實施例以兩個凸板53的豎直面531緊抵於第一直立面415的方式，能增加與第一直立面415接觸的面積，以提升被第一直立面415阻擋時的穩固性。當然，在其他實施方式中，凸板53的數量也可為一個。 In addition, the rod body 551 of each lever 55 abuts against the corresponding second wall 232 and is blocked by it, and the vertical surface 531 of each convex plate 53 abuts against the first straight surface 415 and is blocked by it. , So that the housing 2 and the operating button 4 can play the role of blocking the safety lock 5, so as to prevent the shift lever 55 from being accidentally touched and pressed by a child to rotate in the first direction of movement D1, thereby causing the blocking plane 521 of the baffle 52 to escape The bottom 414 situation. In this embodiment, the vertical surface 531 of the two convex plates 53 abuts against the first vertical surface 415, which can increase the contact area with the first vertical surface 415, so as to improve the resistance when blocked by the first vertical surface 415. Stability. Of course, in other embodiments, the number of convex plates 53 may also be one.

參閱圖9及圖10，欲操作操作裝置200以使鎖定件解除鎖定狀態時，首先，使用者以食指及中指施力將兩撥桿55的撥片552往上撥動，以帶動安全鎖5沿第二運動方向D2旋轉。安全鎖5沿第二運動方向D2旋轉的過程中，擋板52的擋止平面521會於立板412的底面414轉動並逐漸移離底面414，每一個凸板53的豎直面531會移離第一直立面415，且凸台54壓縮第二彈簧7使其變形並蓄積復位彈力。當每一個撥桿55的弧形面553接觸到對應側板3的弧形限位面312並且被其擋止時，安全鎖5即無法再轉動而被限位在釋鎖位置，此時，擋止平面521及豎直面531分別移離底面414及第一直立面415。 9 and 10, when the operating device 200 is to be operated to release the locking member from the locked state, first, the user uses the index finger and middle finger to force the paddles 552 of the two levers 55 to move upward to drive the safety lock 5. Rotate in the second direction of movement D2. During the rotation of the safety lock 5 in the second movement direction D2, the blocking plane 521 of the baffle 52 will rotate on the bottom surface 414 of the vertical plate 412 and gradually move away from the bottom surface 414, and the vertical surface 531 of each convex plate 53 will move away The first straight surface 415, and the boss 54 compresses the second spring 7 to deform it and accumulate the return elastic force. When the arc-shaped surface 553 of each lever 55 touches the arc-shaped limit surface 312 of the corresponding side plate 3 and is blocked by it, the safety lock 5 can no longer rotate and is limited in the unlocked position. At this time, the block The stop plane 521 and the vertical surface 531 are moved away from the bottom surface 414 and the first straight surface 415 respectively.

參閱圖11，隨後，使用者能以拇指將操作殼體42往下按壓，以帶動操作鈕4沿第一運動方向D1旋轉。操作鈕4旋轉過程中會透過卡塊122拉動鋼索121移動，使鋼索121帶動鎖定件移動。同時，殼罩410扭轉第一彈簧6使其變形並蓄積復位彈力。當操作鈕4的立板412的第二直立面416(如圖3所示)接觸到第一壁部231並且被其擋止時，操作鈕4即無法再轉動而被限位在操作位置，此時，鎖定件在解鎖狀態，使用者能依照需求調整桌板11(如圖1所示)的傾斜角度。 Referring to FIG. 11, the user can then use the thumb to move the operating housing 42 down Press to drive the operating button 4 to rotate along the first movement direction D1. During the rotation of the operating button 4, the locking block 122 will pull the steel cable 121 to move, so that the steel cable 121 drives the locking member to move. At the same time, the housing 410 twists the first spring 6 to deform it and accumulates the return elastic force. When the second upright surface 416 (as shown in FIG. 3) of the vertical plate 412 of the operating button 4 contacts the first wall 231 and is blocked by it, the operating button 4 can no longer be rotated and is restricted in the operating position. At this time, the locking member is in the unlocked state, and the user can adjust the inclination angle of the table top 11 (as shown in FIG. 1) according to requirements.

藉由兩撥桿55位於擋板52相反側並供撥動的設計方式，能提升對第二轉軸51及擋板52的施力均勻性，以使擋板52能順暢地轉動並移離立板412。當然，在其他實施方式中，撥桿55的數量也可為一個。由於第二運動方向D2相反於第一運動方向D1，因此，使用者需以兩個相反的方向分別先後操作安全鎖5及操作鈕4，才能解除鎖定件的鎖定狀態。藉此，能提升操作裝置200在操作時的技巧性及難度，以避免安全鎖5及操作鈕4兩者受到誤觸壓力時輕易地被觸動而導致鎖定件解鎖。此外，使用者能夠以透過左手或右手的單手操作方式撥動安全鎖5以帶動其解鎖，以及按壓操作鈕4使其拉動鋼索121移動，藉此，能提升使用操作上的方便性。 With the design of the two levers 55 located on the opposite side of the baffle 52 and for turning, the uniformity of the force applied to the second rotating shaft 51 and the baffle 52 can be improved, so that the baffle 52 can rotate smoothly and move away from the stand.板412. Of course, in other embodiments, the number of the shift lever 55 can also be one. Since the second movement direction D2 is opposite to the first movement direction D1, the user needs to operate the safety lock 5 and the operating button 4 in two opposite directions to release the locked state of the locking member. Thereby, the skill and difficulty of the operation device 200 during operation can be improved, so as to prevent both the safety lock 5 and the operation button 4 from being easily touched when the safety lock 5 and the operation button 4 are accidentally touched to cause the locking member to be unlocked. In addition, the user can toggle the safety lock 5 through a left-handed or right-handed single-handed operation to drive it to unlock, and press the operating button 4 to pull the wire 121 to move, thereby enhancing the convenience of use and operation.

參閱圖8及圖11，待桌板11的傾斜角度調整完成後，使用者便能同時釋放操作鈕4及安全鎖5。藉由第一彈簧6及第二彈簧7所蓄積的復位彈力分別帶動操作鈕4沿第二運動方向D2(如圖10 所示)旋轉及安全鎖5沿第一運動方向D1旋轉，使得操作鈕4及安全鎖5能自動地分別復位至初始位置及鎖定位置。此時，鎖定件藉由彈簧回復至鎖定狀態並將桌板11定位在調整後的傾斜角度位置。 8 and 11, after the tilt angle of the table board 11 is adjusted, the user can release the operating button 4 and the safety lock 5 at the same time. The return elastic force accumulated by the first spring 6 and the second spring 7 respectively drives the operating button 4 along the second movement direction D2 (as shown in Fig. 10 Shown) The rotation and safety lock 5 rotates along the first movement direction D1, so that the operating button 4 and the safety lock 5 can be automatically reset to the initial position and the locked position, respectively. At this time, the locking member is restored to the locked state by the spring and positions the table top 11 at the adjusted tilt angle position.

需說明的是，本實施例的操作鈕4及安全鎖5的運動方式雖然是以旋轉為例作說明，但在本實施例的其他實施方式中，兩者的運動方式也可以是滑動。例如操作鈕4可沿前後方向X滑動地連接於外殼20，且操作鈕4由初始位置運動到操作位置的第一運動方向D1為一後移方向。安全鎖5可沿上下方向Z滑動地連接於外殼20，且安全鎖5由鎖定位置運動到釋鎖位置的第二運動方向D2為一上移方向。藉此，安全鎖5同樣能達到在鎖定位置時阻擋操作鈕4以防止其沿第一運動方向D1運動的功效。 It should be noted that although the movement modes of the operating button 4 and the safety lock 5 in this embodiment are illustrated by taking rotation as an example, in other embodiments of this embodiment, the movement modes of the two may also be sliding. For example, the operating button 4 is slidably connected to the housing 20 in the front-rear direction X, and the first movement direction D1 in which the operating button 4 moves from the initial position to the operating position is a backward movement direction. The safety lock 5 is slidably connected to the housing 20 in the up and down direction Z, and the second movement direction D2 in which the safety lock 5 moves from the locked position to the unlocked position is an upward movement direction. Thereby, the safety lock 5 can also achieve the effect of blocking the operating button 4 in the locked position to prevent it from moving along the first movement direction D1.

綜上所述，本實施例的操作裝置200，藉由安全鎖5阻擋操作鈕4以防止其沿第一運動方向D1運動的設計方式，能防止操作鈕4不慎被誤觸時產生轉動並透過纜線12帶動鎖定件解除鎖定狀態，藉此，能提升使用上的安全性，故確實能達成本發明之目的。 In summary, the operating device 200 of the present embodiment is designed to prevent the operating button 4 from moving in the first direction of movement D1 by blocking the operating button 4 by the safety lock 5, which prevents the operating button 4 from rotating and causing it to be accidentally touched. The cable 12 drives the locking member to release the locked state, thereby improving the safety in use, so that the purpose of the invention can be achieved.
