Abstract:
A connection device comprising a hook member and a casing member,the hook member being elongated about an axis and having a slide portion on an inner end and a hook portion on an outer end, the casing member having a slide bore in which the slide portion of the hook member is slidably received for sliding inwardly and outwardly parallel the axis with the hook portion extending out of the slide bore and with the hook member rotatable relative the casing member about the axis, a spring coupled between the hook member and the casing member to bias the hook member axially outwardly from the slide bore and to bias the hook member to rotate in one direction relative the casing member about the axis, a camming recess in the slide portion opening radially of the axis and presenting a camming surface therein, the casing member having an actuator bore extending transverse to the slide bore from an outer open end into the slide bore, an actuator member displaceable within the actuator bore between an outer position and an inner position, the actuator member having a camming protuberance at its inner end for engaging the camming surface, wherein with the camming protuberance extending into the recess engagement between the camming surface and the camming protrusion prevents withdrawal of the hook member from the casing member and the spring biases the hook member to urge the camming surface into engagement with the camming protuberance which engagement determines the position of the hook member relative the casing member both axially and rotationally, in moving the actuator member from the outer position towards the inner position, the camming protuberance cams on the camming surface against the bias of the spring to both draw the hook member axially inwardly into the casing member and rotate the hook member relative the casing member.
