PROBLEM TO BE SOLVED: To provide a structure in which flip-up operation can be performed by releasing a lock state safely and reliably in a table whose top plate can be flipped up.SOLUTION: A lever member 22 is mounted to an upper bracket 21 fixed to a top plate 1 so as to be horizontally rotatable. A bearing member 24 is fixed to a front leg post 4. The top plate 1 is locked in a horizontal posture by engaging a lower claw part 23b of a movable lock body 23 provided in the lever member 22 with an upper ring part 24a of the bearing member 24 from below. When the lever member 22 is rotated and the lower claw part 23b of the movable lock body 23 retreats, a pusher 26 built in the bearing member 24 is raised by a spring 25 and the top plate 1 is slightly flipped up. During flip-up operation, there is no need for a person to pay attention to the top plate 1 so as not to be flipped up to an upper limit, thus reducing burden on the person. Even when the top plate 1 is long in the right and left, the lock can be released one by one.SELECTED DRAWING: Figure 9 |
