  • QUICK COUPLER
    Publication number: 20240018740
    Abstract: This invention related to a coupler for securing an attachment to an earth working machine. The coupler comprises a coupler body that presents a receptacle having a capture region. A pin of an attachment can move into and out of the capture region. A retainer can capture the pin in the capture region but the retainer can be moved by a hydraulically driven driver to a position to allow release the pin from the capture region. A trigger that the pin will strike when the pin moves into or out of the capture region, decouples the driver from the retainer and the retainer is then allowed to be biased back to its retaining position by a spring.
