Abstract
Abstract A folding step having a mounting plate and a step member. The mounting has a back face and a front face and is adapted to be mounted against a surface to be climbed with its back face flush against the surface. A recess is provided in the back of the plate and an opening extends through the plate between the recess and the front face. The step member is mounted through the opening from the recess. Cooperating means are provided on the plate and step member for preventing the step member from passing completely through the opening from the recess. The step member is movable in the opening between a horizontal operative position where it projects transversely from the front face of the mounted plate, and an upright stored position where it lies generally parallel to, and against, the plate.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
229 words
A folding step comprising a mounting plate and a step member wherein: said mounting plate has a front face and a back face, means on the back face for use in fixing the mounting plate to a vertical surface to be climbed, said mounting plate having an upper surface angled downwardly towards the surface to which the plate is to be mounted, a first recess in the back of the mounting plate, a second recess in the front of the mounting plate, the first and second recesses intersecting to form an opening through the plate, said opening extending through the top and bottom of the plate, said front face forming a support cross-bar, said front face having a centrally located elongated vertical slot therein, said slot being continuous from the top of said front face to the bottom thereof; said step member having an elongated upper face, co-operating means at a first end of said face for retaining said step member in said first recess when said step member is in an operative position, an upwardly extending flange extending from an opposed second end of said upper face of said step member, said flange being angled inwardly such that said flange will seat on said downwardly angled upper surface of said mounting plate when in a stored position to thereby securely retain the step member in the storage position.
Claim 2
Dependent Claim
229 words
A folding step comprising a mounting plate and a step member wherein: said mounting plate has a front face and a back face, means on the back face for use in fixing the mounting plate to a vertical surface to be climbed, said mounting plate having an upper surface angled downwardly towards the surface to which the plate is to be mounted, a first recess in the back of the mounting plate, a second recess in the front of the mounting plate, the first and second recesses intersecting to form an opening through the plate, said opening extending through the top and bottom of the plate, said front face forming a support cross-bar, said front face having a centrally located elongated vertical slot therein, said slot being continuous from the top of said front face to the bottom thereof; said step member having an elongated upper face, co-operating means at a first end of said face for retaining said step member in said first recess when said step member is in an operative position, an upwardly extending flange extending from an opposed second end of said upper face of said step member, said flange being angled inwardly such that said flange will seat on said downwardly angled upper surface of said mounting plate when in a stored position to thereby securely retain the step member in the storage position.
Claim 3
Dependent Claim
46 words
The folding step as claimed in claim 1 wherein the first recess is wider than the second recess and the co-operating means comprises a surface adjacent the opening defining part of the first recess and lateral projecting means on the step member co-operating with the surface.
Claim 4
Dependent Claim
42 words
A folding step as claimed in claim 1 wherein said step member has a reinforcing flange extending downwardly from a lower surface of said face, said flange adapted to fit within said vertical slot of the front face of said mounting plate.
