Abstract

Abstract A ALEASA for ladders is comprised of three pieces which when attached to one side of a ladder near its base and adjusted will have the effect of lengthening that side to keep the ladder vertical while resting on an angled plane; or when an ALEASA is attached to each side of a ladder near its top and are adjusted, they will have the effect of extending the ladder to rest against a wall while allowing the top of both sides of the ladder to be free of any contact with the wall; or when an ALEASA is attached to a ladder near its top, and adjusted, it will have the effect of extending that side of the ladder to rest against an angled or different wall while keeping the two sides of the ladder parallel with each other.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 467 words
An adjustable ladder extender assembly safety attachment (ALEASA), including A. A bracket of a channel shaped member having three walls and an open side with a diverging member protruding from the wall opposite and extending away from the open side wherein the diverging member is multi-sided, but preferably an eight-sided prism shaped solid member whose sides are perpendicular to the side to which it is secured and has a hole through the member that is exposed on two sides which are opposite each other, and which are on the same plane as the walls of the channel-shaped member which are adjacent to the open side and holes in both walls adjacent to the open side are dimensioned and positioned to allow for securing the device to a ladder or the like; B. A hollow member having several walls, but preferably four walls with a diverging member protruding from one wall and protruding away from its opposite wall wherein the diverging member is multi-sided, but preferably an eight-sided prism-shaped hollow member whose sides and walls are perpendicular to the wall on which it is secured and dimensioned to envelope and house the diverging member as described in A above; and C. A bar having several sides, but preferably four sides with a series of holes eminating from one side and each hole being exposed on both the eminating side and its opposite side; and wherein each side of the diverging member as described in B above has a hole dimensioned and designed to allow a bolt or the like to be placed through any two opposite sides of the diverging member and, when so positioned, through the hole in the diverging member as described in A above; and wherein holes are dimensioned and positioned in two opposite walls of the hollow member as described in B above and eminate from the wall on which the diverging member is secured to allow a bar as described in C above to be held in place within the hollow member when said bar is passed through said hollow member and bolts or the like are put through opposing holes in opposite walls of said hollow member, and when so positioned, through designated holes in said bar and wherein the bracket, the hollow member and the bar, as described in A, B and C above, respectively, form the ALEASA, which can be attached to a ladder or the like and adjusted so that said ladder may be placed in any desired position; and wherein the ALEASA may be made of any suitable material; and wherein the ALEASA may be made in various sizes and shapes; and wherein the ALEASA may be modified to accommodate other objects, designs, and purposes, which may become apparent to those skilled in the art from this disclosure.
