The brackets are pivotally bolted to magnet mounts, which each hold a permanent magnet that releasably holds the ladder in place against the support. The apparatus prevents the ladder from slipping, and further serves to hold the ladder at the proper angle for safe use. The apparatus finds particular application where exposed ferromagnetic metal beams are available in the workspace but tying a ladder for safety would be impractical.

Abstract: A platform is provided with a ladder to allow the user to easily ascend to the platform. A pair of stabilizing arms and jaws provides lateral stability to the ladder. A climbing stick has a pair of vertical posts attached between the front and rear walls of steps to provide a secure connection. The upper and lower ends extend inwardly and away from each other to provide a gripping surface. A tree stand has a male adapter with a bracket for securing a strap. The strap is used to secure the male adapter in place. Once secured to the tree, the platform area can be attached to the male adapter using a female adapter. The ability to first secure the smaller, lighter bracket and male adapter to a tree before attaching the platform using a female adapter increases the ease in securing the tree stand to a tree.

Abstract: A ladder includes a leveler engages a bottom of each side rail for 1) causing extendable legs to move to a level ground-engaging position, 2) causing the legs to lock when both legs engage the ground, and 3) causing the extendable legs to move to a centered/retracted position when lifted from the ground. The leveler includes pawls, links, pinions, and a shaft forming a four-bar linkage for selectively moving the pawls inward to the disengaged position when the pinion and shaft are each freely rotatable, but selectively moving the pawl outward into locking engagement when the shaft resists movement due to ground engagement by both legs. The leveler can be constructed to attach to an inside of the side rails, thus facilitating pre-assembly.
