A rotation control mechanism comprises a first rotating member, a second rotating member, and a first locking pin. The first rotating member is provided with a pin hole. The second rotating member is provided with a locking hole. The first locking pin is inserted into the pin hole and the locking hole to lock the first rotating member and the second rotating member. The first locking pin and the first rotating member are circumferentially limited and movably arranged in an axial direction. A first elastic member is connected to the first locking pin and applies an action force to the first locking pin to be inserted into the locking hole. The second rotating member is provided with a trigger portion, and the first rotating member is provided with an elastic braking portion. The folding ladder comprises two ladders and two rotation control mechanisms.

The invention is directed to a device that allows a user to enter and exit a bathtub or other apparatus with a relatively high sidewall safely and easily. Particularly, the device comprises first and second sides that can be positioned on either surface of a bathtub sidewall. The first and second sides each include one or more braces that support a plurality of steps that enable a user to climb up one side of the device and down the other. The device can include one or more stabilizers that are sized and shaped to allow a user to securely grab onto as they advance up or down the steps, thereby maintaining balance. Advantageously, the first side can be rotated up and above the second side using hinges or any other rotatable element.

An multi-position ladder is disclosed that includes an adjustable top cap that provides a tool or material tool tray when the ladder is in a stepladder position and provides a step when the ladder is in an extension ladder position is disclosed. The top cap generally comprises a rigid frame extending between the adjustable hinges of the multi-position ladder with a tool or utility tray and a step surface on opposing sides. The tool tray is parallel to the ladder rungs when the ladder is in a stepladder position, and the step surface provides a generally planar surface parallel the rungs when the ladder is in an extension position. The rigid frame of the top cap adds strength to the adjustment hinge and to the multi-position ladder. Embodiments allow for 12-inch hinge spacing, adding one foot reach in the extension position and six inch reach to the stepladder.

A ladder and ladder accessory are provided including an accessory that may be coupled to the ladder in multiple configurations and serve multiple purposes. In one embodiment, a pair of components are each selectively coupled with associated rails of a ladder in a first, stored state, and a second, walkthrough state. When in the walkthrough state, the components extend upwards from and above the rails so that a user may gasp the components and step between the components when transitioning from the ladder to an elevated surface (e.g., a roof) or vice versa. In another embodiment, the components may be coupled to the ladder such that they extend in a direction that is substantially transverse to a plane through which the rails extend. When in this transverse orientation, the components may be used as a stand-off device.

A ladder is disclosed which has a lockable pivot arrangement. The lockable pivot arrangement is located and connected between two elongate ladder sections. Inside each pair of end housings there are at least two receptacles. A pivot mechanism connects between the end housings and the end housings rotate in unison and also allow the pair of end housings to rotate relative to the housing. A lock mechanism within the housing has at least two lock members each with an actuator and each actuator having a free end. There is an elastomeric bias element acting to bias the two lock members and respective free ends and actuators away from each other, and the two actuators when biased apart are positioned so as to allow for one-handed actuation against the bias to unlock the rotation of the housing.
