Abstract (en)
The present invention (10) discloses a stepladder having a ladder portion (18) that is comprised of rungs (24) and includes two ladder side rails, and a support portion that includes two angularly disposed telescoping support legs (20) that provide mechanism for stabilizing the ladder. The support legs (20) are interconnected to each other and to the ladder side rails by lockable rigid spanner arms (22). Furthermore, each of the support legs comprises a locking mechanism for securing the support legs to the ladder portion making the tripod stepladder easier to handle and transport. The present invention (10) also provides a retractable fly assembly (52) at the top of the ladder rails to provide for additional usable working height and alternately removable extension members with the upper stepladder portion having hollow support leg shoes. A safety belt (36) is provided on the retractable handle for additional support. A series of apertures with lock key fasteners (28) in each of the support legs provide mechanism for the user to securely position the legs at a desired length. The lock key fastener (28) includes a locking pin that engages an aperture in the corresponding leg to secure the desired position. Indicia are further provided for aiding in leveling the ladder.
