摘要： A lock set for a door has a cylindrical spindle integrally coupled with a knob and containing a slide plate which can be actuated to lock and unlock the cylindrical spindle against rotation. The cylindrical wall of the spindle is provided with two diametrically opposing grooves which extend axially from one end thereof to a predetermined depth and which are opened at the one end so as to facilitate installation of the slide plate in the spindle. The slide plate has two opposing lugs for insertion into the grooves.

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。

摘要： A reinforcing apparatus for a lever handle of a door lock includes a housing fixed to a door and provided around a driving shaft of the door lock. The housing has a wall transverse to the driving shaft. The wall has a hole formed therethrough for passage of the driving shaft. A rotary member is mounted in the housing for rotating simultaneously with the driving shaft. The rotary member is sleeved on the driving shaft and has an engaging plate which projects axially from an outer peripheral edge thereof. A coiled spring is provided around the rotary member for biasing the rotary member to return and maintain the lever handle at its original unoperated position after the rotary member is rotated by the lever handle. The coiled spring has two legs extending radially outwardly to abut against the engaging plate. One of the legs is displaceable by the engaging plate. The housing further includes a stopping unit provided on the wall thereof. The stopping unit is aligned radially with and is located outwardly of the engaging pate when the lever handle is in the unoperated position. The other one of the legs is kept immobilized by the stopping unit when the rotary member rotates.
摘要翻译： 用于门锁的把手的加强装置包括固定到门并围绕门锁的驱动轴设置的壳体。 壳体具有横向于驱动轴的壁。 壁具有穿过其形成的通孔用于驱动轴的通过。 旋转构件安装在壳体中以与驱动轴同时旋转。 旋转构件套在驱动轴上，并且具有从其外周边缘轴向突出的接合板。 旋转构件周围设置有用于偏置旋转构件的螺旋弹簧，以在旋转构件通过杆手柄旋转之后使杠杆手柄返回并保持在其原始未操作位置。 螺旋弹簧具有径向向外延伸以抵靠接合板的两个腿。 腿中的一个可由接合板移动。 壳体还包括设置在其壁上的止动单元。 当杠杆手柄处于未操作位置时，止动单元与接合孔的径向对准，并且位于接合孔的外侧。 当旋转构件旋转时，另一个腿由止动单元保持固定。
