    • A latch actuator mechanism (10) having a housing (18) in which is mounted a lever (40 ) that engages a carrier member (54) that surrounds a spindle (66). The spindle includes a radial projection (74) that engages a recess (60) in the carrier member (54) such that as the lever (40) is pivoted, it linearly displaces the carrier member which in turn bears upon the projection (74) to rotate the spindle (66). The spindle is connected to a latch (16) that extends transversely to the axis of the spindle and is actuated for engagement and disengagement to strike (82). The preferred latch mechanism includes an elongated latch case (88) mounted transversely on the spindle (66), the latch having a retractor member (96) mounted for linear displacement longitudinally within the case and a latch bolt head (114) adapted for a projected and a withdrawn position relative to the case. An annular, semi-circular hub (92) is affixed to the spindle within the case for converting the rotational motion of the spindle into a linear displacement of the retractor member, whereby the bolt head may be drawn to its retracted position. A spring member (112) interposed between the forward portion of the retractor member and the hub provides a forward bias on the retractor member such that upon release of the latch actuating force on the spindle, the retractor and bolt head will automatically return to the forward, or engaged position.
    • 具有壳体(18)的闩锁致动器机构(10)安装有与围绕主轴(66)的承载构件(54)接合的杆(40)。 主轴包括一个径向突起(74),该径向突起(74)与承载构件(54)中的凹部(60)接合,使得当杠杆(40)枢转时,它使线性地移动承载构件,承载构件又承载在突出部(74)上, 以旋转主轴(66)。 主轴连接到横向于主轴的轴线延伸的闩锁(16),并被致动以接合和分离以撞击(82)。 优选的闩锁机构包括横向安装在心轴(66)上的细长闩锁壳体(88),闩锁件具有安装成用于在壳体内纵向线性位移的牵开器构件(96)和适于投影 以及相对于壳体的撤回位置。 环形半圆形轮毂(92)固定在壳体内的心轴上,用于将心轴的旋转运动转换成牵开器构件的线性位移,由此螺栓头可以被拉到其缩回位置。 介于牵开器构件的前部和轮毂之间的弹簧构件(112)在牵开器构件上提供向前的偏压,使得当释放主轴上的闩锁动作力时,牵开器和螺栓头将自动返回到前进 ,或接合位置。

    • A compact cylinder lock operated by a key having smooth edges and detents in opposed side faces. The locking mechanism includes series connected pin tumblers and side bars which are resiliently biased. A resiliently biased locking bar having locking lugs extending therefrom cooperates with the side bars and lock housing; the locking bar moving out of engagement with the housing and into gates in the side bars when the side bars are moved a sufficient distance by the pin tumblers. The side bars are provided with false gates which engage the lugs on the locking bar to prevent unauthorized opening of the lock.
    • 一个紧凑的圆筒锁,由一个具有平滑边缘的键和相对的侧面的棘爪操作。 锁定机构包括串联连接的销子翻转开关和弹性偏置的侧杆。 具有从其延伸的锁定凸耳的弹性偏压锁定杆与侧杆和锁壳体配合; 当侧杆通过销倒钩移动足够的距离时,锁定杆移动离开与壳体的接合并进入侧杆中的门。 侧杆设置有假门,其与锁定杆上的凸耳接合以防止未经授权打开锁。

    • A cylinder lock system employing a key having a projection extending from each opposing parallel edge of the key blade, the projections respectively operating an auxiliary pin tumbler stack and cooperating with a groove in the lock shell to retain the key in the lock after plug rotation from the key insertion position. The key retaining projection also cooperates with the driver pin of the auxiliary pin tumbler stack to prevent key trapping, i.e., the presence and size of the retaining projections keeps the auxiliary driver pin from engaging the keyway. The cooperation between the key retaining projection and the auxiliary driver pin is permitted by providing the lock with two shear lines, located on different diameters, which are simultaneously operable by a single key.
    • 一种圆筒锁系统,其采用具有从所述键叶片的每个相对的平行边缘延伸的突起的键,所述突起分别操作辅助销翻转开关,并且与所述锁壳中的凹槽配合,以在从所述键壳旋转之后将所述键保持在所述锁中 关键插入位置。 钥匙保持突起还与辅助销翻转突起的驱动销配合以防止钥匙捕获,即,保持突起的存在和尺寸保持辅助驱动销不与键槽接合。 通过提供锁具有位于不同直径上的两个剪切线,可以通过单个键同时操作,允许钥匙保持突起与辅助驾驶员销之间的协作。
