ABSTRACT:
In the first embodiment, a coupling assembly is provided wherein the inner peripheral diameter of an annular spring is sized to be threadably received over the threads of a coupler and is held in a recess formed by the ends of threads and the edge of a shoulder. This structure minimizes the diameter of the annular spring and lock ring to minimize both the size and weight of coupling assembly. Additionally, it provides a quick connect, quick disconnect coupling and has a peripheral stripe to provide a visual indication of its connected or disconnected status. In the second embodiment, a wavy spring is split which allows its diameter to be temporarily enlarged so that it can be received over the threads of the coupler and then spring back to its original smaller diameter so that it is held in a recess formed by the ends of the threads and a coupler flange. This structure also minimizes the diameter of the annular spring and lock ring to minimize both the size and weight of coupling assembly. This structure also provides a quick connect, quick disconnect coupling and has an indicator stripe to identify whether or not the coupler is in locked position.
