The present disclosure discloses a folding ladder and a top tray thereof. The top tray comprises a fixed plate and a movable plate. The movable plate is disposed on a rear side of the fixed plate and is rotatably connected to the fixed plate, and the movable plate is configured to be rotated to switch between an unfolded position and a folded position. When the movable plate is in the unfolded position, the movable plate is horizontally arranged side-by-side with the fixed plate, and a rear surface of the fixed plate abuts a front surface of the movable plate to maintain the movable plate in a horizontal position and to resist a downward force of gravity. When the movable plate is subjected to an upward pushing force and is rotated to be folded into the folded position, the movable plate abuts the rear side of the fixed plate.

A collapsible ladder includes a first pair of legs and a second pair of legs, each of the first pair of legs and the second pair of legs is rotatably joined near tops thereof; a plurality of steps extending between one of the first pair of legs and one of the second pair of legs, each of the steps rotatably jointed about a mid-point thereof; a first vertical spar slidably connected to each of the steps near the mid-points thereof; a plurality of supports extending between a second one of the first pair of legs and a second one of the second pair of legs, each of the supports rotatably jointly about a mid-point thereof; and a second vertical spar slidably connected to each of the supports near the mid-points thereof. This configuration allows the ladder to be collapsed by raising the first and second vertical spars causing the steps and supports to fold about their mid-points permitting the first and second pair of legs to be generally folded/collapsed into a single column.

A brace locking mechanism locks the foldable braces of a folding ladder in the open position. The brace locking mechanism is used with a ladder that has a stepped unit and a support unit foldably attached to the stepped unit with a foldable brace extending between the stepped unit and the support unit. The brace locking mechanism comprises a lock block that is movable between a locked position in which the lock block prevents the foldable braces from moving out of their open position when the ladder is open, and an unlocked position in which the ladder may be folded into the storage position.

A locking mechanism for a ladder tray is disclosed. The locking mechanism includes two locking points on the frame or handle of the ladder while allowing single-handed operation.

A step stool includes an expandable tray assembly. The expandable tray assembly has a fixed tray panel and a movable tray panel coupled to the fixed tray unit for movement relative to the fixed tray unit. The movable tray panel is illustratively movable between a collapsed position, arranged above the fixed tray panel, and an expanded position, arranged adjacent to the fixed tray panel.
