    • A changeable lock assembly suitable for re-keying a lock without disassembly of the lock. The assembly includes a housing having a bore therein, and a plug rotatably mounted in the bore. The plug includes a longitudinal axis and a keyway. The keyway is adapted to receive at least a first user key and a second user key. The lock further includes a change member movable within the lock between a first position to a second position. The change member can move solely in response to operation of the second key. Thus, when the change member is in the first position, the first key operates the lock, and when the change member is in the second position, the first key does not operate the lock. The lock assembly can also employ a change tool that, when inserted into a change slot, can move a change ball from the second position back to the first position.
    • 一个可更换的锁组件,适用于重新锁定锁而不拆卸锁。 组件包括其中具有孔的壳体和可旋转地安装在孔中的插头。 插头包括纵向轴线和键槽。 键槽适于接收至少第一用户密钥和第二用户密钥。 所述锁还包括可在所述锁中在第一位置与第二位置之间移动的变化构件。 改变构件可以仅响应于第二个键的操作而移动。 因此,当改变构件处于第一位置时,第一键操作锁,并且当改变构件处于第二位置时,第一键不操作锁。 锁组件还可以采用一种改变工具,当插入更换槽时,可以将换球从第二位置移回到第一位置。

    • A plug assembly for use in a key-operated lock, having a cylindrical key plug that can rotatable between a key insertion position and a control position, the key plug having a keyway and tumbler bores, an axial groove into the periphery displaced tangentially from the tumbler bores, a curved trough extending radially inwardly from the carriage groove, a control tooling slot formed radially inwardly from the curved trough. A carriage is moveable axially within the carriage groove, and has an outer surface proximate with the cylindrical periphery of the key plug. The carriage has radially-formed retainer bores that align tangentially with the tumbler bores when the carriage is in a position to accept lock configuration change balls. A separate change tooling blade can be inserted into the control tooling slot to raise any change balls within the retainer bores out through an outer opening the retainer bore.
    • 一种用于钥匙操作的锁的插头组件,具有能够在钥匙插入位置和控制位置之间旋转的圆柱形钥匙塞,钥匙插头具有键槽和制动栓孔,从外部切向切换到外围的轴向槽, 滚筒孔,从滑架槽径向向内延伸的弯曲槽,从弯曲槽径向向内形成的控制工具槽。 滑架可在滑架槽内轴向移动,并且具有与键塞的圆柱形周边接近的外表面。 滑架具有径向形成的保持孔,当托架处于接受锁定构型改变球的位置时,定位孔与制动栓孔相切对准。 可以将单独的更换工具刀片插入到控制工具槽中,以通过保持器孔的外部开口将保持器孔内的任何换向球推出。
