  • Patent number: 10899321
    Abstract: An outrigger device that is mounted on a vehicle and can switch between a usage state and a storage state includes: a lateral outrigger that extends in a vehicle width direction of the vehicle; a vertical outrigger that is extendable and is rotatably coupled to a leading end portion of the lateral outrigger; a first coupling member that constantly couples a first part of the vertical outrigger to the lateral outrigger and serves as a rotational center of the vertical outrigger; a second coupling member that can switch between a first state where a second part of the vertical outrigger is coupled to the lateral outrigger and a second state where the second part is uncoupled from the lateral outrigger; a conversion mechanism that converts a retraction of the vertical outrigger into an upward rotation of the vertical outrigger; and a safety device that prohibits an operation of the conversion mechanism in the first state and permits the operation of the conversion mechanism in the second state.
