20080236947 | ASSEMBLABLE LADDER - An assemblable ladder comprises two upright first and second supports, and side plates, mounting members, and screwing elements severing to couple the two first supports together, and to connect the two second supports together. By using a cover piece and other screwing elements, the two coupled first supports and the two connected second supports are assembled together. By way of other screwing elements, pedals are attached between the parallel first and second supports, and connection members are disposed between the pedals and one of the two first supports, or between the pedals and one of the two second supports. Besides, fastening pieces are secured between another parallel first and second supports, and other connection members are fixed between the fastening pieces and the other of the two first supports, or between the fastening pieces and the other of the two second supports, thereby easily assembling the ladder in a DIY manner. | 10-02-2008 |
20090107764 | Lower ladder support - The lower ladder support is a device adapted for use with a two-railed ladder of the extension type and functions to prevent the ladder from moving, sliding or kicking back during use. The device includes identical support assemblies attached to the rails of the ladder at a lower portion thereof. Each assembly includes a channel, a circular plate having an array of apertures therein, a strap-plate member and rods for attaching the strap-plate, circular plate and channel to a respective rail. The channel is dimensioned to receive and removably retain an elongate, inexpensive, 2×4 wood stock member or similar member therein. The 2×4 member functions as an additional support leg for the ladder. | 04-30-2009 |
20090211845 | Lockable folding stairs - A two-piece locking folding stair is provided with a spring-like locking mechanism. The spring-like device, deployed one on of the two members, includes a protruding member which engages a notch on the other member when the stairs are in the full open, or locked position. When the stairs are opened, the device moves into a position which prevents the stairs from folding unintentionally. To unlock the assembly, the spring-like device is depressed thus releasing the protruding member from a corresponding notch, allowing the stairs to be folded to the closed position for stowing or transport. | 08-27-2009 |
20100200334 | Step stool latch - A step stool includes a first section having at least a first step. The step stool includes a hinge bracket connected to the first section. The step stool includes a second section connected to the hinge bracket having a crossbar; and a platform having a latch that moves only in translation to lock the platform to the cross bar when the platform is in a horizontal position and prevents the first section and second section from folding when the first and second sections are in an open state. A method for establishing a step stool includes the steps of moving a latch of a platform only in translation away from a crossbar of a second section that the platform rests on in a horizontal position. There is the step of placing the second section and a first section having at least one step together into a closed position. | 08-12-2010 |
20150361720 | PIVOTING STAIRS - A swiveling staircase is provided for access to a device disposed above the ground at a distance that a person of an ordinary height is not able to reach. The staircase includes an immobile upright stanchion and a staircase assembly pivotally coupled to the stanchion. The staircase assembly includes a platform on the top of a plurality of stairs. The staircase assembly rotates between a first position where the staircase is docked out of way for storage and a second position where the staircase assembly is facing the front side of the device so that an operator standing on the platform may be able to reach the device. | 12-17-2015 |
182172000 | Lateral prop | 7 |
20090045013 | Ladder stabilizer - A ladder stabilizer for use with a ladder having a pair of side rails with rungs extending therebetween, the ladder stabilizer comprising first and second rear legs designed to extend rearwardly of the ladder, first and second lateral legs designed to extend laterally of the ladder, the first and second rear legs being interconnected with each other, the first and second rear legs also being connected to a respective side rail of the ladder, with flexible cables extending between the lateral legs and the first interconnecting member. | 02-19-2009 |
20090107765 | Extension ladder stabilizer - An extension ladder stabilizer includes a pair of generally elongated, spaced-apart ladder mount members; a pair of generally elongated stabilizer legs swivelly carried by the pair of ladder mount members, respectively; a pair of leg braces having a pair of leg receptacles, respectively, swivelly carried by the pair of ladder mount members, respectively. In a functional or ladder-stabilizing configuration of the extension ladder stabilizer, the pair of ladder mount members is adapted to receive the pair of stabilizer legs which in turn engage the ground or floor and the pair of leg receptacles is adapted to removably receive the pair of stabilizer legs, respectively. A stabilized extension ladder is also disclosed. | 04-30-2009 |
20110017549 | STABILIZER KIT FOR PROVIDING REINFORCING SUPPORT TO A LADDER - A stabilizer for use with a ladder including a first elongated portion terminating in a bracket securing to a frame location of the ladder and a second portion telescopically connected to the first portion and terminating in angled foot support. The bracket includes a first component pivotally secured to the first elongated portion and a second inter-engageable component secured to the ladder. The first elongated component exhibits a pair of outer spaced and extending portion between which extends the second portion. A pivotal handle is located at an interface between the first and second elongated portions and exhibits an engaging surface for releasably locking the first and second elongated portions together. | 01-27-2011 |
20120103727 | Outrigger Stabilizer And Ladder Combination - An outrigger stabilizer combined with a ladder includes a telescoped outer tube and inner elongated member with a one way brake freely allowing telescoping movement of the inner member out of the outer tube to automatically adjust to engage the ground but instantly locking together when any collapsing movement is attempted to brace the ladder in any adjusted position. | 05-03-2012 |
20120168253 | Ladder stabilizer - A ladder stabilizer for use with a ladder having a pair of side rails with rungs extending therebetween, the ladder stabilizer comprising first and second rear legs designed to extend rearwardly of the ladder, first and second lateral legs designed to extend laterally of the ladder, the first and second rear legs being interconnected with each other, the first and second rear legs also being connected to a respective side rail of the ladder, with flexible cables extending between the lateral legs and the first interconnecting member. | 07-05-2012 |
