    • An overcenter type latch for relatively movable members includes a retainer of molded plastic secured to one member and having spaced recesses adjacent one end thereof and a striker adjacent the other end thereof. An operating handle has spaced abutments adjacent one end thereof received within the retainer recesses for pivotal movement of the handle between an overcenter latched position and an unlatched position. An elastomeric link is pivoted to the operating handle and to other member. The link is tensed when the handle is in latched position and extends between the spaced recesses and abutments. A manually operated latch integral with the handle cooperates with the striker to block movement of the handle to unlatched position unless the latch is manually released.
    • 用于相对可动构件的超中心型闩锁包括固定到一个构件并具有与其一端相邻的间隔开的凹槽的模制塑料保持器和邻近其另一端的撞针。 操作手柄具有邻近容纳在保持器凹槽内的一端的间隔的邻接部,用于在超中心锁定位置和解锁位置之间使手柄枢转运动。 弹性体连杆枢转到操作手柄和其它构件。 当把手处于锁定位置并且在间隔开的凹部和基台之间延伸时,连杆被拉紧。 与手柄一体的手动操作的闩锁与撞针配合,以阻止把手的移动到解锁位置,除非手动释放闩锁。

    • A latch for use with a boat hatch comprises a housing having a well, a floor, and a flange mounted against the boat hatch. The housing has a boss with a bushing and a vertical bore. A slot extends transversely through the boss and the vertical bore. A pull shaft with an annular O-ring is mounted in the bushing bore. A rotation stop pin on the pull shaft will contact the slot, limiting the rotation to one-half turn. A latch bar projects outward from the pull shaft lower end. A D-shaped handle is pivotally mounted on the pull shaft upper end. A spring is disposed below the rotation stop, to bias the pull shaft downward. A lock shaft is mounted for rotation in the housing. A hook with a finger is attached to the lock shaft. A key rotates the hook into engagement with the second pin. The second pin, enclosed between the finger and the boss slot, prevents rotation of the pull shaft and unlatching of the latch.
    • 用于船舱的闩锁包括具有井,地板和安装在船舱上的凸缘的壳体。 壳体具有带衬套和垂直孔的凸台。 狭槽横向延伸穿过凸台和垂直孔。 具有环形O形圈的拉动轴安装在衬套孔中。 拉动轴上的旋转止动销将接触槽,将旋转限制在二分之一圈。 闩锁杆从拉杆下端向外突出。 D形手柄可枢转地安装在拉杆上端。 弹簧设置在旋转止动件下方,以将拉动轴向下偏置。 锁定轴安装在壳体中旋转。 带有手指的钩子附着在锁定轴上。 钥匙将钩旋转成与第二销接合。 封闭在手指和凸台槽之间的第二针防止拉动轴的旋转和闩锁的松开。
