Abstract
Abstract An upstanding ladder is provided including opposite side stiles and vertically spaced horizontal rungs extending between and interconnecting the stiles. A platform has one marginal portion thereof pivotally mounted from the uppermost rung with the platform being generally horizontally disposed and extending outwardly of one side of the ladder. The stiles project above the ladder and the base ends of a pair of arms are pivotally mounted from the stile upper ends for swinging about horizontal axes paralleling the ladder rungs. The outer free ends of the arms are interconnected by an outwardly opening V-shaped tree trunk embracing brace extending and secured therebetween and seat structure is mounted from and extends between the outer ends of the arms and is spaced outward from the base ends of the arms pivotally mounted from the stile upper ends. A pair of inclined braces are provided and the upper ends of the braces are removably pivotally anchored relative to the outer ends of the arms, the lower ends of the braces are removably pivotally anchored to the stiles at points spaced below the uppermost rung and the mid-portions of the braces are pivotally anchored relative to the platform intermediate the inner and outer marginal portions thereof. Further, the ladder comprises vertically aligned upper and lower telescopingly engaged ladder sections with the platform, arms and braces being mounted from the upper ladder section and the one marginal portion of the platform extending between the stiles being free of portions thereof projecting outwardly of the sides of the stiles remote from the sides thereof outwardly from which the arms project.
