Abstract
This invention is a simple to make, simple to use, inexpensive step for use on rectangular wooden posts, such as those used in scaffolds. This step has a u shaped body with a portion that encompasses the posts, two "grips" in this portion which bite into the wood to keep the step in place, and a part to step upon. To move this step to a desired position, the part that is stepped upon is tilted up and out from the horizontal. This motion causes the two grips to disengage from the post and to be sufficiently removed from the post to allow the step to slide freely on this post. The step is fabricated from a single sheet of metal that is cut and bent to the desired design.
Claims14
A portable, vertically movable step, for connection to a substantially vertical, rectangular post, comprising:
- (a) a substantially U shaped body formed of sheet material and having a pair of planar parallel side pieces spaced apart so as to encompass and contact two opposite sides of said rectangular post;
- (b) said side pieces having sufficient length to present two legs that extend outwardly beyond the side of the post they encompass;
- (c) the bight of said U shaped body being planar and positioned to contact a third side of said rectangular post;
- (d) means to contact the fourth side of said rectangular post when said step is in a substantially horizontal position but to avoid contact with said fourth side when the legs are tilted upwardly away from said substantially horizontal position so that said step, when in the tilted position, may then be moved upwardly and downwardly on said post.
