摘要： A lockset suitable for use on doors of different thicknesses comprises inside and outside knobs mounted on inside and outside spindles which are in turn rotatably supported in inside and outside chassis. Rotation of either knob causes rotation of a rectangular driver spindle to drive a latch operating assembly which retracts a latchbolt. Locking may be accomplished only by pressing a push button located in the inside knob. In one embodiment the push button drives a caliper spring to engage and axially move a plunger bar and in a second embodiment a hook spring carried on the push button engages teeth on the plunger bar. Axial movement of the plunger bar actuates a clutch mechanism to disconnect the outside knob from the driver spindle and lock the outside knob to the outside chassis to prevent rotation of the knob. In the first embodiment unlocking is accomplished by rotating the plunger bar relative to a coupler having a spring thereon for engaging notches on the plunger bar. The unlocking may be accomplished with a key from the outside or by turning the inside knob. In the second embodiment unlocking is accomplished from the inside by turning a knob to rotate the plunger bar and from the outside unlocking is accomplished by turning a key to rotate the coupler. Both embodiments may be mounted on doors of various thicknesses without any adjustment prior to mounting. The second embodiment permits hands free installation.
摘要翻译：适用于不同厚度的门的锁具包括安装在内部和外部主轴上的内部和外部旋钮，这些旋钮可旋转地支撑在底盘内部和外部。任一旋钮的旋转引起矩形驱动器主轴的旋转，以驱动闭锁闩锁的闩锁操作组件。只能通过按下位于内部旋钮中的按钮来实现锁定。在一个实施例中，按钮驱动卡钳弹簧以接合和轴向移动柱塞杆，并且在第二实施例中，承载在按钮上的钩弹簧接合柱塞杆上的齿。柱塞杆的轴向运动致动离合器机构以将外部旋钮与驱动器主轴断开，并将外部旋钮锁定到外部框架以防止旋钮旋转。在第一实施例中，解锁是通过使柱塞杆相对于其上具有弹簧的联接器旋转来实现的，用于接合柱塞杆上的凹口。解锁可以用来自外部的钥匙或通过转动内部旋钮来实现。在第二实施例中，通过旋转旋钮使柱塞杆旋转，从内部实现解锁，并且通过转动钥匙以使联接器旋转来实现解锁。两个实施例可以安装在各种厚度的门上，而无需在安装之前进行任何调整。第二实施例允许免提安装。
