A spindle lock includes a spring (44) and a detent (41, 43) arrangement to control and buffer the rotation of a spindle (28) and to delay the engagement of locking elements (24a, 24b). In some embodiments, the spindle lock includes a spring element (44) which applies substantially equal spring force to delay the operation of the spindle lock when the spindle (28) is rotated in the forward direction or in the reverse direction. In other embodiments, the spindle lock provides two spring members which cooperate to apply the substantially equal force to delay the operation of the spindle lock when the spindle (28) is rotated in the forward direction or in the reverse direction. <IMAGE> |
