摘要： A mechanism that allows a ladder to be moved to either a use position or a retracted position. The ladder can be moved from the retracted position to the use position with a minimal effort, and the ladder moves by itself from the use position to the retracted position. A pit ladder apparatus for an elevator according to the present invention includes a position change means to be provided in a fixing metal frame fixed to the hoistway and allowing a ladder to be moved to either the use position when the ladder is used or the retracted position for retracting the ladder when it is not used so as not to interfere with operation of the elevator.

摘要： This is a system that allows a small child to escape from a window well using a ladder and a window well cover. The ladder extends from the bottom of the window well cover and has a trigger that when activated slides the ladder and releases a trap door in the window well cover, thus allowing a person to climb the ladder and escape through the cover.

摘要： The present invention is for a step stool to be used by a child, diminutive person or an adult of average height to gain vertical reach. The retractable step stool/access device is positioned by one's foot between an elevated, retracted position or a lowered, deployed step accessible position. Internal stored energy mechanisms can be employed to ease some of the physical effort required, especially by a child or diminutive person, to complete the deployment/retraction cycle with either of their feet. In the raised, retracted position, the step stool is elevated from contact with the floor and clear of the standing area for general usage and allowing access for cleaning and maintenance of the floor.

摘要： A ladder assembly for use with movable shelving is disclosed. The ladder assembly may comprise an overhead track assembly, a carriage, and a ladder. The overhead track assembly includes a first guide track and a second guide track. The carriage is operatively configured to move longitudinally along the first and second guide tracks. The ladder is pivotally and slidably mounted to the carriage. The ladder has an operating position and a stored position. The operating position is located in an open available aisle of the movable shelving. The stored position may be located substantially vertical and outside of the aisle of the movable shelving allowing the movable shelving to close the aisle without interference from the ladder.

摘要： 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.
