    • A brake for a medical table (20) includes a speed detector (40) for determining when the table speed is greater than a threshold value. If the table is moving at greater than the threshold value, the brake is prevented from engaging to prevent the patient from being jolted. When the brake is engaged, teeth (91-95) of a brake tooth member (90) mesh with a groove set assembly (70). The teeth have central planes (A). Each of the teeth has sidewalls that define planes (P1 and P2) which make acute angles with respect to the respective central planes. A position detector (110) warns an operator when the brake is not engaged. A linear bearing assembly (125) guides the brake into the engaged position. A pawl assembly (100) hold the brake in the engaged position until released.
    • 用于医疗台(20)的制动器包括速度检测器(40),用于确定表速度何时大于阈值。 如果桌子移动大于阈值,则制动器被阻止接合以防止患者被颠簸。 当制动器接合时,制动齿构件(90)的齿(91-95)与槽组件(70)啮合。 牙齿有中心平面(A)。 每个齿具有限定相对于各个中心平面形成锐角的平面(P1和P2)的侧壁。 当制动器未接合时,位置检测器(110)警告操作者。 线性轴承组件(125)将制动器引导到接合位置。 棘爪组件(100)将制动器保持在接合位置,直到释放。

    • An apparatus is provided for securely positioning a medical device that prevents movement of one end of the device by applying a single force. The apparatus allows a doctor to depress a pedal, which is connected to a pedal housing by way of a single shaft. Connected to the ends of the shaft are two separate linkage members. The first linkage member is attached to a ratcheting mechanism that steers the pedal into the locked position. The second linkage member is connected to a cam within the pedal housing that drives a spring-loaded plunger assembly. When the pedal is in the locked position the plunger assembly is in contact with the floor, thereby preventing movement of the device. To release the braking device, the doctor depresses the pedal slightly, which causes the ratcheting mechanism to allow the pedal, and therefore the plunger assembly, to return to their unlocked positions.
    • 提供一种用于牢固地定位医疗装置的装置,其通过施加单个力来防止装置的一端移动。 该装置允许医生按下通过单个轴连接到踏板壳体的踏板。 连接到轴的端部是两个单独的连接构件。 第一联动构件附接到将踏板转向锁定位置的棘轮机构。 第二连杆构件连接到踏板壳体内的凸轮,该凸轮驱动弹簧加载的柱塞组件。 当踏板处于锁定位置时,柱塞组件与地板接触,从而防止装置移动。 为了释放制动装置,刮刀稍微压下踏板,这使得棘轮机构允许踏板,从而使柱塞组件返回到其解锁位置。
