    • An artificial joint including a main body and a lower portion adapted to pivotally engage the main body about a control axis while having a locking means that is integral with the lower portion. An upper portion adapted to pivotally engage the main body about a flexing axis and has an engagement means adapted to engage and disengage the locking means upon the pivoting rotation of the upper portion relative the main body. A biasing means is adapted to engage both the main body and the lower portion thereby biasing the locking means to engage the engagement means, and at least one stopping surface adapted to limit motion between the main body and the lower portion. The locking means is activated when a load is imposed on the artificial joint and passes through a line posterior to the control axis, and is desactivated when the load passes through a line anterior to the control axis.
    • 一种人造关节,其包括主体和下部,其适于在具有与下部一体的锁定装置的同时围绕控制轴枢转地接合主体。 上部部分适于绕着弯曲轴线枢转地接合主体,并且具有接合装置,该接合装置适于在上部相对于主体的枢转旋转时接合和解除锁定装置。 偏置装置适于接合主体和下部部分,从而偏压锁定装置以接合接合装置,以及适于限制主体与下部之间运动的至少一个止动面。 当负载施加在人造关节上并通过控制轴后面的线时,锁定装置被激活,并且当负载通过控制轴之前的线时,锁定装置被激活。
