    Abstract: A coincidental lock adapted for vehicle steering column applications includes a steering shaft lock bolt movable between locking and unlocking positions, lock means operable by a key to move the lock bolt between its positions, and inhibitor means operable to prevent locking movement of the lock bolt as long as the key is inserted in the lock means, the inhibitor means including an inhibitor pin, a slipring, a key bezel rotatable with the key, cam means on the key bezel engageable on the slipring, and means connecting the slipring and the inhibitor pin. The key, when inserted in the bezel, displaces the cam means to a position depressing the slipring and the latter, when so depressed, functions to yieldingly urge the inhibitor pin to a position preventing locking movement of the lock bolt once the latter achieves the unlocking position.

    Abstract: In a vehicle steering column having a main steering shaft, an intermediate shaft rotatable as a unit with the main shaft, an adjustable shaft rotatable as a unit with the intermediate shaft and axially bodily shiftable relative to the latter, and a steering handwheel rigidly attached to the adjustable shaft, a locking arrangement between the intermediate shaft and the adjustable shaft including a rod threadedly received on the intermediate shaft perpendicular to the adjustable shaft, and a semicircular key on the intermediate shaft engageable by an end of the rod and defining a lever operative to multiply the force exerted by the rod and apply the multiplied force to the adjustable shaft. The force exerted by the key on the adjustable shaft generates a proportional friction force which prevents relative axial movement between the adjustable shaft and the intermediate shaft.

    Abstract translation: 在具有主转向轴的车辆转向柱中，作为与所述主轴一体地旋转的中间轴，与所述中间轴作为一个单元可旋转并且相对于所述主转向轴轴向身体移动的可调节轴，以及刚性地附接到 所述可调节轴，所述中间轴和所述可调节轴之间的锁定装置包括螺纹地容纳在垂直于所述可调节轴的所述中间轴上的杆以及所述中间轴上的半圆形键，所述中间轴可由所述杆的端部接合并且限定杆 以增加由杆施加的力并将相乘的力施加到可调节的轴上。 由钥匙施加在可调节轴上的力产生比例摩擦力，防止可调节轴与中间轴之间的相对轴向运动。
