Patent number: 11904921Abstract: 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.Type: GrantFiled: August 6, 2020Date of Patent: February 20, 2024Assignee: MAKITA CORPORATIONInventors: Yasuo Ifuku, Susumu Kato
