Benefits of technology

The present patent provides an improved work platform that can be folded and adjusted in both height and width. The work platform can be easily transformed between an open and closed configuration, and can be locked in place to prevent unintentional changes. The platform has folding leg frames that can be adjusted in length and width using a single hand, and includes bumper / handles for easy carrying. The work platform can be made of metal, plastic, or fiberglass, and includes a proximal rung member, intermediate rung member, and base rung member for added stability. The work platform also includes laterally extendable feet for improved contact with the ground or supporting surface. The folding work platform provides increased adjustability and ease of use compared to previous folding work platforms.

Problems solved by technology

Ladders and step stools are inconvenient because they have a narrow width and require continued movement to work on an area of more than a couple feet in length.
Although the fixed height of the elevated work surface provides a stable platform, the fixed height may necessitate the tradesperson or homeowner having to stretch to reach the desired work area, or having to bend over or crouch to perform the desired work.
Such abnormal posture, particularly for an extended period of time, can result in unnecessary fatigue and / or less than optimal performance.

Embodiment Construction

[0034]Referring to FIGS. 1-3, a work platform 100 is depicted in accordance with an embodiment of the disclosure. The work platform 100 can be configured to be adjustable in both height and width, while enabling ease in transformation between an open, use configuration (as depicted in FIG. 1) and a closed, storage configuration (as depicted in FIGS. 2 and 3).

[0035]The work platform 100 can include a platform 102 (alternatively referred to as a “work surface” or “elevated work surface”) and a first and second leg frame 104A and 104B pivotably coupled to the platform 102. The platform 102 can have a first end 106A, a second end 106B, and a longitudinal plane 108 defined by outer perimeter 110. In one embodiment, the platform 102 can be manufactured of any formable, rigid, durable material, such as metal, plastic or fiberglass. For example, in one embodiment, the platform 102 can be constructed of a plurality of extruded aluminum planks, operably coupled to one another by one or more b...

Abstract

A work platform configured to be adjustable in both height and width, while enabling ease in transformation between an open, use configuration in a closed, storage configuration. The work platform having a platform and a pair of leg frames pivotably coupled to opposite ends of the platform, each of the pair of leg frames including a first leg and a second leg, each of which includes a first member pivotably coupled to the platform, and a second member shiftable relative to the first member, an intermediate rung operably coupled to respective distal ends of the first members and including a length extension lock mechanism configured to inhibit shifting of the second members relative to the first members, and a base rung member including a crossmember operably coupled to the respective distal ends of the second members.

Description

RELATED APPLICATION INFORMATION[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 621,312, filed Jan. 24, 2018, the contents of which are fully incorporated herein by reference.TECHNICAL FIELD[0002]The present disclosure relates generally to portable work platforms, and more particularly to a collapsible work platform configured to provide a stable elevated work surface.BACKGROUND[0003]Professional tradespersons such as painters, drywall installers, and electricians require an elevated work surface upon which to stand to reach the location of their work. Homeowners, too, have the need for elevated platforms for various home improvement projects. Ladders and step stools are inconvenient because they have a narrow width and require continued movement to work on an area of more than a couple feet in length. Therefore, many tradespersons and homeowners use a work platform to provide elevation with extended length.[0004]Work platforms and scaffolds are well ...
