摘要： A shoe bracket assembly 10 for attachment to a foot of a ladder rail 50 has a channel member 12 and a bracket 14 affixed to the base 16 of the channel member. The bracket is positioned between end walls 18, 20 of the channel member. The bracket has a central portion 22 with first and second flanges 24, 26 extending outwardly so as to be affixed to the base of the channel member. The bracket also has third and fourth flanges 28, 30 extending outwardly from the central portion so as to be in spaced but parallel relationship to the base of the channel member. The lower end of the rail is received within the space. The central portion has a hole 32 in axial alignment with a hole 34 in the channel member. A ladder shoe 62 may be pivotally connected to the assembly via these holes.

摘要： A configurable ladder system that can be configured into any of a plurality of different ladder configuration modes and methods for manufacturing and using same. The configurable ladder system includes at least one side rail and at least one support member and can be configured into any of a plurality of different ladder configuration modes. Each support member is disposed on a relevant side rail or on an optional adjustable rail. Depending upon a selected ladder configuration mode of the configurable ladder system, two or more of the support members can be configured to engage respective support regions within an intended work environment of the configurable ladder system. Thereby, the configurable ladder system advantageously can be readily adapted for use within a wide range of different purposes within a large number of a different work environments while enhancing user safety.

摘要： A ladder apparatus has a first ladder section having a pair of side rails and a plurality of rungs extending between the side rails, a second ladder section hingedly connected to the first ladder section adjacent an upper end of the first ladder section, and a latch mechanism affixed to one of the ladder sections and engageable with the other of the first and second ladder sections. The second ladder section is movable between an extended position and a retracted position. The latch mechanism is adapted to secure the second ladder section in the retracted position. The second ladder section will extend in generally parallel relation to the first ladder section when in this retracted position. A ladder top is affixed to the upper end of the first ladder section and extends outwardly therefrom so as to have an end surface positioned away from the first ladder section.

摘要： A step stool apparatus has a front leg unit, a rear leg unit hingedly connected to the front leg unit, and a platform pivotably mounted at a pivot axis of the front leg unit. The platform has a top surface with a front edge and a rear edge, the front edge of the platform being positioned at or rearwardly of the pivot axis of the platform. The platform has a peripheral surface at a front end thereof that is positioned at or forwardly of the pivot axis. An angled surface extends from the peripheral surface toward the front edge of the top surface of the platform. The front edge of the top surface of the platform is positioned such that a downward force applied to the top surface at any location on the top surface will not cause the rear end of the platform to separate from abutment with the strut of the rear leg unit.
