  • Patent number: 4820094
    Abstract: A rope hook arrangement for a vehicle has a case fixed to the vehicle body and a movable member slidable rectilinearly in the case. A rope hook fixed to one end of the movable member can be projected from the vehicle body and retracted. A spring is disposed between the case and movable member so that the movable member is always urged outwardly. A latch lever is swingably mounted on the movable member, and first and second pins are fixed to the case. The first pin engages with the latch lever and holds the movable member in a middle position in which the rope hook is snugly retracted. If the movable member is pushed down to a depressed position by hand, and unhanded at that position, the first pin pushes the latch lever to a release position, so that the movable member is lifted up by the spring to a projected position in which the rope hook is projected from the vehicle body.

  • Patent number: 4820093
    Abstract: A rope hook arrangement for a vehicle has a case fixed to a vehicle body, and a movable member slidable rectilinearly in the case so that a rope hook fixed to the movable member can be projected from the vehicle body and retracted. A spring is disposed between the case and movable member for urging the movable member to a projected position. A push-lock-push-release mechanism is provided for holding the movable member in a middle position in which the rope hook is retracted, allowing the movable member to move to the projected position when the movable member is depressed from the middle position to a depressed position and unhanded at the depressed position, and allowing the movable member to return to the middle position when the movable member is depressed from the projected position to the depressed position and unhanded. The push-lock-push-release mechanism comprises a rotatable member mounted on the case, and engaging and actuating projections formed in the movable member.
