ABSTRACT:
A safety post assembly for assisting entry to or exit from the upper portion of a wall having mounted thereon a series of rungs forming a ladder, the assembly comprising a tubular support sleeve; adjustable mounting means for securing the sleeve to the rungs in an upstanding position; an elongated extension rod having a tapered lower end portion for sliding insertion into the tubular sleeve and an opposite upper end portion adapted to extend above the upper portion of the structure and provide grasping means during the entry and exit; a projection extending outwardly from the extension rod, and adapted to rest against the upper end of the sleeve for limiting insertion of the rod lower end portion into the sleeve to a predetermined distance sufficient to support the weight of a person grasping the rod upper end portion during the entry and exit; and a step member extending transversely on opposite sides of the extension rod between the upper and lower end portions and positioned to provide a foothold in the vicinity of the upper portion of the structure during the entry and the exit, the transverse member including a flange on either side of the extension rod and bolt means passing through the extension rods and the flanges to secure the member to the rod. The extension rod is entirely directly removable from the sleeve by grasping the rod and urging the rod in an upward direction. The assembly further includes means to counterbalance the weight of the extension rod when the lower end of the rod is inserted in the support sleeve, the counterbalance means comprising a spring disposed within the sleeve, the spring having a first end portion secured to the sleeve and a second end portion biased into a wound coil, the spring second end portion being engagable by the rod lower end portion to unwind the coil as the rod is inserted to the predetermined distance, the spring offsetting a substantial portion of the weight of the extension rod when the rod is inserted into the sleeve.
