Abstract: A two-step step stool includes a primary stool and a secondary stool. The primary stool includes a primary supporting plate and a primary pedal hinged with a top of the primary supporting plate. The secondary stool includes a secondary supporting plate and a secondary pedal hinged with a top of the secondary supporting plate. The secondary pedal is higher than the primary pedal. A middle plate is arranged between the primary stool and the secondary stool and is respectively hinged with the primary pedal and the secondary pedal. A linkage mechanism capable of folding the primary stool and the secondary stool synchronously is further arranged between the primary stool and the secondary stool. The two-step step stool can be drawn close towards the middle plate when being folded by hinging the primary pedal with the middle plate and hinging the secondary pedal with the middle plate.

Abstract: A collapsible ladder includes a first pair of legs and a second pair of legs, each of the first pair of legs and the second pair of legs is rotatably joined near tops thereof; a plurality of steps extending between one of the first pair of legs and one of the second pair of legs, each of the steps rotatably jointed about a mid-point thereof; a first vertical spar slidably connected to each of the steps near the mid-points thereof; a plurality of supports extending between a second one of the first pair of legs and a second one of the second pair of legs, each of the supports rotatably jointly about a mid-point thereof; and a second vertical spar slidably connected to each of the supports near the mid-points thereof. This configuration allows the ladder to be collapsed by raising the first and second vertical spars causing the steps and supports to fold about their mid-points permitting the first and second pair of legs to be generally folded/collapsed into a single column.

Abstract: First and second forward legs have pivot ends and free ends. First and second rearward legs have pivot ends and free ends. Four pivot brackets are provided. Two of the four pivot brackets extend rearwardly from each forward leg. In this manner the angle between the forward and rearward legs may be varied. Also provided is a top step, a middle step, and a bottom step. Each step is horizontal when in a ladder orientation. Further provided is an imperforate tongue. The imperforate tongue is pivotably secured between the rearward legs adjacent to the free ends. In this manner the rearward legs may be perpendicularly positioned when in a dolly orientation. Provided last are four wheels. Four wheels are secured to the forward legs. The four wheels extend forwardly from the forward legs for use when in a cart orientation.

Abstract: A telescoping ladder includes a stabilizer connected to a stabilizer housing proximal to the floor surface on which the ladder is positioned. The first stabilizer can move between an extended position and a collapsed position. In the extended position, the first stabilizer extends out of a hollow body portion of the stabilizer housing and collapse into the hollow body portion of the rung in the collapsed position. The stabilizer comprises a locking button to lock the stabilizer in its extended position. The ladder comprises a flange that can release the locking button thereby unlocking the stabilizer from its extended position and move it into the collapsed position.

Abstract: The disclosed lightweight portable ladder provides a stable platform that can nest in close proximity to helicopters, aircraft and other machines to facilitate enhanced access for inspection and maintenance. The ladder consists of a stepped unit connected by hinged means located near the top a support unit and means to hold the units in a fixed orientation. The distance from the hinge point to the bottom of the support unit is longer than from the hinge point to the bottom of the stepped unit. The hinge point may be located some distance below the top of the stepped unit, in which case the upper portion of that unit will be cantilevered with respect to the hinge point. The location of the hinge point can be tailored for specific aircraft and applications so as to provide an optimized fit when the ladder is positioned for use.

Abstract: A folding step stool includes a front rail assembly. The step stool includes a rear rail assembly, pivotally connected to the front rail assembly, having a crossbar. The step stool includes a step pivotally attached to the front rail assembly having notches which fit over the crossbar when the stool is in an open position. The step stool includes a linkage assembly pivotally and fixedly attached to the step and pivotally and fixedly attached to the crossbar. The linkage assembly compresses to allow the notches to fit over the crossbar and the linkage assembly exerting a force to maintain the crossbar in the notches when the stool is in the open position. A method for securing a step stool includes the steps of moving the notches of a step against a crossbar of a rear rail assembly pivotally connected to a front rail assembly of the step stool. There is the step of compressing a linkage assembly pivotally and fixedly attached to the step and pivotally and fixedly attached to the crossbar to allow the notches to fit over the crossbar. There is the step of exerting a force with the linkage assembly to maintain the crossbar in the notches when the stool is in the open position.
