Abstract: A coupling arrangement capable of being released while the coupling is under considerable tension and particularly adapted to connect an object to a roller chain or similar device having at least two cross elements like the rollers of a chain. A lever has an offset front end which engages one of the cross members and has a coupling element pivoted to its other end to engage the other crossed element. The offset end of the lever is recessed to pivotally engage the first cross element and the coupling element has a recess which engages under the second cross element. The line of force between the lever and object is offset to one side of the first cross element to provide a moment of force that assists pivoting the lever to a released position about the first cross element. A spring urged latch normally maintains the coupling element in its locked position in which pivotal movement of the lever about the first cross element is prevented.

Abstract translation: 联接装置能够在联接器处于相当大的张力下被释放，并且特别适于将物体连接到具有至少两个诸如链条的滚子的交叉元件的滚子链或类似装置。 杠杆具有偏移前端，其接合所述横向构件中的一个，并且具有枢转到其另一端的联接元件以接合另一个交叉的元件。 杠杆的偏移端凹入以枢转地接合第一十字元件，并且联接元件具有接合在第二十字元件下方的凹部。 杠杆和物体之间的力线偏移到第一十字元件的一侧，以提供力矩的力矩，其有助于将杠杆转动到围绕第一十字元件的释放位置。 弹簧推动的闩锁通常将联接元件保持在其锁定位置，在该位置中杆被围绕第一横向元件的枢转运动被阻止。
