    • A push button lock for mounting at an opening formed through a door panel near an edge of the door includes a flush mountable exterior housing having a thin mounting flange that encircles central housing portions that are configured to extend into the door panel opening, and a surface mountable interior housing that defines a bolt passage that carries a spring-projected slide bolt having an end formation configured to latchingly engage a suitably configured striker. The interior housing and the mounting flange of the exterior housing overlap and are clamped toward engagement with interior and exterior door panel portions that extend about the opening. The interior and exterior housings define button passages that intersect with the bolt passage, within which interior and exterior push buttons are slidably carried, with inner end regions of the buttons defining inclined cam surfaces that are configured to matingly engage separate interior-facing and exterior-facing inclined cam surfaces formed on the slide bolt so that, when either of the buttons is pressed, the engagement of its cam surface with one of the cam surfaces of the slide bolt will cause the slide bolt to retract from latchingly engaging the striker. A key-operated lock cylinder carried by the exterior housing and a locking knob carried by the interior housing each are operable to move a locking cam into and out of the path of the slide bolt to selectively permit and prevent slide bolt retraction.
    • 一种用于安装在通过靠近门边缘的门板形成的开口处的开关的按钮锁具有一个可嵌入式的外部外壳，该外壳具有一个薄的安装凸缘，该安装凸缘围绕构造成延伸进入门板开口的中心壳体部分， 该可安装的内部壳体限定了一个螺栓通道，该螺栓通道具有弹簧突出的滑动螺栓，该弹簧突出的滑动螺栓具有构造成闩锁地接合适当构造的撞针的端部结构。 内部壳体和外部壳体的安装凸缘重叠并且被夹紧以与围绕开口延伸的内部和外部门板部分接合。 内部和外部壳体限定与螺栓通道相交的按钮通道，内部和外部按钮可滑动地被携带，其中内部和外部按钮可滑动地承载，其中内部端部区域限定倾斜的凸轮表面，其被配置成配合地接合单独的面向内部和外部的按钮， 形成在滑动螺栓上的面对倾斜的凸轮表面，使得当按压任一个按钮时，其凸轮表面与滑动螺栓的凸轮表面之一的接合将导致滑动螺栓从闩锁地接合撞针而缩回。 由外壳承载的钥匙操作的锁芯和由内部壳体承载的锁定旋钮均可操作以将锁定凸轮移入和滑出滑动螺栓的路径，以选择性地允许和防止滑动螺栓缩回。

    • A slam-capable, flush-mountable, paddle handle operated rotary latch having a pan-shaped housing employs a single rotary jaw that is releasably retained in its latched position by a rotary pawl, with the latch having spaced first and second housing side plates that sandwich the rotary jaw, the rotary pawl and a torsion spring that biases the jaw toward an open position, with the side plates defining aligned first and second U-shaped notches that cooperate with a third U-shaped notch formed in the rotary jaw for concurrently receiving and latchingly retaining a suitably configured strike formation, with the first housing side plate being rigidly connected to the pan-shaped housing, and with the second housing side plate being rigidified in close proximity to its U-shaped notch by an integrally formed flange that extends transversely to bridge between the housing side plates. The pawl defines a release trigger which, when tripped, permits the jaw to be pivoted by the spring to an open position. An operating arm is connected to the housing for pivotal movement along a back wall of the housing for tripping the trigger in response to operation of the handle. The operating arm has opposed end regions, one of which engages the release trigger and is guided for movement by extending through a slot formed in the first side plate, the other of which is guided for movement by a backwall-mounted guide, and is engageable by a lockable cam for selectively permitting and preventing the handle and arm from moving to trip the trigger.
    • 一种具有冲击能力的可嵌入式桨叶手柄操作的具有盘形壳体的旋转闩锁采用单个旋转夹爪，其通过旋转爪可释放地保持在其锁定位置，闩锁具有间隔开的第一和第二壳体侧板， 夹住旋转爪，旋转爪和扭力弹簧，使得钳口朝向打开位置偏压，侧板限定对准的第一和第二U形凹口，其与形成在旋转夹爪中的第三U形凹口配合，用于同时 接收和闩锁地保持适当地构造的撞击结构，其中第一壳体侧板刚性地连接到盘形壳体，并且第二壳体侧板通过整体形成的凸缘紧邻其U形凹口而被刚性化， 横向延伸到壳体侧板之间的桥。 棘爪限定释放触发器，当触发时，释放触发器允许钳口由弹簧枢转到打开位置。 操作臂连接到壳体，用于沿着壳体的后壁枢转运动，以响应于手柄的操作而使触发器跳闸。 操作臂具有相对的端部区域，其中一个端部接合释放触发器并且通过延伸穿过形成在第一侧板中的槽而被引导以移动，另一端被引导以由后壁安装引导件移动，并且可接合 通过可锁定的凸轮来选择性地允许和防止手柄和臂移动以使触发器跳闸。
