Gooseneck Trailer with Coupling Link and Latch Actuators

A trailer with a detachable gooseneck, comprising a deck supported toward the rear by ground engaging wheels, mating surfaces on the gooseneck and the deck which abut against each other when the gooseneck is attached to the deck, coupling pins extending along spaced apart, parallel axes from the gooseneck and the deck on opposite sides of the abutting surfaces, a coupling link movable along the pin on the gooseneck between a first position in which the link engages the pin on the deck and a second position in which the link is disengaged from the pin on the deck, an operating arm engagable with the coupling link, and an actuator mounted on the gooseneck and connected to the operating arm for moving the coupling link between the first and second positions.

A trailer with a detachable gooseneck, comprising a deck supported toward the rear by ground engaging wheels, mating surfaces on the gooseneck and the deck which abut against each other when the gooseneck is attached to the deck, coupling pins extending along spaced apart, parallel axes from the gooseneck and the deck on opposite sides of the abutting surfaces, a coupling link slidably mounted on the pin on the gooseneck with a socket for receiving the pin on the deck when the link is in a first position, a bar spaced from and affixed to one side of the coupling link, an operating arm mounted on the gooseneck for movement about a pivot axis perpendicular to the axes of the coupling pins, with a first end portion of the operating arm extending in a direction generally parallel to the pivot axis and passing between the one side of the coupling link and the bar, and an actuator connected to a second end portion of the operating arm for rotating the arm about the pivot axis and swinging the first end portion of the arm toward the bar to move the coupling link to a second position in which pin on the deck is disengaged from the link.

A gooseneck trailer comprising a deck, a gooseneck, coupling pins extending along spaced apart, parallel axes from the gooseneck and the deck, a coupling link movable along the axes between a first position in which the link engages the pins on both the gooseneck and the deck and a second position in which the link engages only one of the pins and is disengaged from the other, and an actuator for moving the link between the first and second positions.

A trailer with a detachable gooseneck, comprising a deck supported toward the rear by ground engaging wheels, downwardly and forwardly inclined surfaces on the gooseneck and the deck which abut against each other when the gooseneck is attached to the deck, coupling pins extending from the gooseneck and the deck along spaced apart, longitudinally extending axes on opposite sides of the abutting surfaces, a coupling link engaging the pins and locking the abutting surfaces together in load supporting relationship, a laterally extending latch bar depending from the gooseneck near the rearmost ends of the abutting surfaces, a latch hook rotatively mounted on the deck for movement between an extended position in which the latch hook is engaged with the latch bar and a retracted position in which the latch hook is disengaged from the latch bar, a pneumatic actuator operatively connected to the latch hook for moving the latch hook between extended and retracted positions, and a spring connected to the latch hook for resiliently urging the latch hook toward the extended position.
