Patent number: 11285598Abstract: A bracket (20) includes: a pedestal (21, 22) that is mountable on a support frame (2) of a work stand (1) for supporting a saw (60); and first and second engaging parts (38A, 38B) arranged on the pedestal to sandwich the support frame in a horizontal direction and engage with first and second engagement parts (8A, 8B) on opposite sides of the support frame. The second engaging part includes first and second levers (41, 42). The pedestal is movable along the longitudinal direction of the support frame by manipulating only the first lever to disengage it from the second engagement part (8B) and is removable from the support frame by simultaneously manipulating both the first and second levers in the same direction to disengage them from the second engagement part. The first and second levers both move in the same opposite direction to engage the second engagement part.Type: GrantFiled: April 21, 2020Date of Patent: March 29, 2022Assignee: MAKITA CORPORATIONInventors: Syuji Aoyama, Toshiyuki Kani, Shoichi Ishikawa
