Abstract

A bottom loading coupler includes a coupler body and a plurality of interlocks. Each interlock is positioned in a slot in the body sidewall and pivotally coupled to the coupler body such that each interlock has an engaged position and a disengaged position with each interlock biased to the disengaged position. A coupler sleeve is slidably positioned around the coupler body and comprises a first, retracted position relative to the coupler body and a second, extended position relative to the coupler body. A biasing element is positioned between the coupler sleeve and the coupler body and biases the coupler sleeve to the second, extended position relative to the coupler body. The interlocks are in the disengaged position when the coupler sleeve is in the first, retracted position and in the engaged position when the coupler sleeve is in the second, extended position.
