摘要： An inner handle assembly of a door lock includes a handle with an axle. A mounting cap has an axial hole for passage of the axle and a through-hole offset from the axial hole. A spindle driving plate has a central hole engaging fittingly a spindle of the door lock. A manually operable lock unit has a button member extending outwardly through the through-hole and mounted for movement in an axial direction between locking and unlocking positions, and an engagement member in connection with the button member. The engagement member engages the spindle driving plate for locking against rotation of the spindle driving plate when the lock unit is at the locking position. A rotary member is mounted on the axle within the mounting cap for rotating simultaneously the axle. The rotary member moves axially and outwardly the engagement member to disengage from the spindle driving plate when the axle is turned to rotate the rotary member. The axle retards rotation of the spindle driving plate so that the spindle driving plate starts to rotate after the lock unit is moved to the unlocking position.

摘要翻译： 门锁的内部把手组件包括具有轴的把手。 安装盖具有用于通过轴的轴向孔和从轴向孔偏移的通孔。 主轴驱动板具有与门锁的主轴嵌合的中心孔。 手动操作的锁定单元具有按钮构件，该按钮构件向外延伸穿过通孔并安装成在锁定和解锁位置之间沿轴向方向移动，以及与按钮构件相关联的接合构件。 当锁定单元处于锁定位置时，接合构件接合主轴驱动板以防止主轴驱动板的旋转。 旋转构件安装在安装盖内的轴上，用于同时旋转轴。 当轴转动以使旋转构件旋转时，旋转构件沿接合构件轴向和向外移动以与心轴驱动板脱离。 该轴延迟主轴驱动板的旋转，使得在锁定单元移动到解锁位置之后主轴驱动板开始旋转。
