摘要： 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.

摘要： A ladder comprises a front leg and a rear leg connected by a slider bracket. The slider bracket comprises a base and a track. The base comprises an aperture therein. The track extends away from the base and comprises a slot therein. The base is rotatably coupled to the front leg by a front pin in the aperture. The track is slidably coupled to the rear leg by a rear pin in the slot. When spreading the rear leg away from the front leg, the base pivots around the front pin as the rear pin slides in the slot of the track until the rear pin reaches the end of the slot in the track. The slot also may include a latch at the end of the slot that engages the rear pin.

摘要： The present disclosure is directed to a ladder system. A ladder system may comprise a first section comprising: a first rail, a second rail, and a first support connected to the first rail and the second rail; a second section comprising a first leg; a first connector for connecting, either directly or indirectly via one or more second connectors, the first section to the second section; and a ladder system-opening facilitator connected to the first section and the second section, wherein the first section is substantially parallel to the second section when the ladder system is in a closed position, wherein the ladder system-opening facilitator automatically completes an opening action for the ladder system in response to initiation of the opening action, and wherein the first section is angular to the second section when the ladder system is in an open position.

摘要： 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.

摘要： A stepladder provided with a coupling frame in the shape of an equilateral triangle, a front support, a rear right support, a rear left support, and spread stoppers for stopping the front support, the rear right support, and the rear left support from spreading. The front support is rotationally attached to a front shaft of the coupling frame, the rear right fixing member is rotationally attached to a right shaft, and the rear left fixing member is rotationally attached to a left shaft. The rear left support and the rear right support are detachably mounted to the rear left fixing member and the rear right fixing member, respectively. The supports of the stepladder are coupled by the spread stoppers, whereby the three supports are restricted from being displaced forward, to the right rear, and to the left rear.
