  • Patent number: 11904921
    Abstract: A handcart may include: a support frame; a container; a lock member configured to move between a locking position at which the lock member restricts rotation of the container relative to the support frame and an unlocked position at which the lock member allows the rotation of the container relative to the support frame; and a retainer member configured to move between a retaining position at which the retainer member restricts a movement of the lock member from the unlocked position to the locking position and a non-retaining position at which the retainer member allows the movement of the lock member from the unlocked position to the locking position. The lock member may be configured to move from the locking position to the unlocked position and be maintained in the unlocked position by a movement of the retainer member from the non-retaining position to the retaining position.

  • Publication number: 20230097550
    Abstract: A working machine may include a first ground-contact part, a driving part configured to drive the first ground-contact part, a clutch mechanism configured to be switched between a transmission state and a non-transmission state, a clutch operation part configured to switch a state of the clutch mechanism, a braking mechanism configured to be switched between a braking state and a non-braking state, and a braking operation part configured to switch a state of the braking mechanism. In a case where the state of the braking mechanism is the braking state, the clutch mechanism may be switched from the transmission state to the non-transmission state by operating the clutch operation part, and in a case where the state of the braking mechanism is the non-braking state, the clutch mechanism may not be switched from the transmission state to the non-transmission state even by operating the clutch operation part.

  • Patent number: 11400966
    Abstract: A handcart may include a support frame, an actuator, a rotating frame configured to be rotated relative to the support frame by the actuator and a container configured to be rotated relative to the support frame. The container may be configured to be rotated with the rotating frame relative to the support frame when the rotating frame is rotated relative to the support frame by the actuator. The rotating frame may be rotatable up to a position at which an angle between the support frame and the rotating frame becomes a first rotation angle. The container may be rotatable up to a position at which an angle between the support frame and the container becomes a second rotation angle, the second rotation angle being greater than the first rotation angle.
