Abstract
A pop-up mechanism is formed of a main frame, supporting poles rotatably coupled to the main frame, an elevating member rotatably attached to the supporting poles, an urging device for urging the supporting poles to rotate in a stand-up direction, and a locking device for locking the elevating member in a pop-up state and in a folded state. The locking device includes a locking piece slidably attached to the elevating member and having a lock releasing projection and a locking hole; a locking member rotatably attached to one of the supporting poles and having a locking pawl; and a locking projection projecting from the main frame. The locking projection is engaged with a locking hole of the locking piece to lock in the folded state, and the locking pawl of the locking member is engaged with a locking dent formed in the elevating member to lock in the pop-up state. When the locking piece is pushed, the locking conditions in the folded state and the pop-up state are released.
