AI Technical Summary

Benefits of technology

The patent describes an improved latchable scaffold board that has clips or brackets attached to each end. These clips are designed to catch a horizontal scaffold member. The board also has a movable latch at one end that moves to a locked position. When the latch is in the locked position, a part of the latch is positioned underneath the horizontal scaffold member, which holds the scaffold board securely to the member. This design makes it easier and safer to use the scaffold board, and ensures stability while working at heights.

Problems solved by technology

Often however, the elevated surface may have to be constructed around a structure or obstacle.
However, the wooden planks are a tripping hazard.
Heavy winds or other uplifting forces can cause such a scaffold board to be dislodged from the scaffold frame.

Embodiment Construction

[0042]The invention is an improved latchable scaffold plank. As shown in the view of FIG. A1, one embodiment of the plank is a board like member 10, having a first and second terminating ends 202, 204, first and second side edges 212, 214, a top surface 40 extending between the two terminating ends 202 and 204 and two side edges 212, 214. Two side rails 70, extending downwardly from the top surface at about ninety degrees, and run substantially the length of the board 10, and are positioned on the scaffold board near the side edges 212 and 214. Positioned at each near terminating ends 202, 204 is at least one shaped clip or cleat, 50, shaped to couple with a horizontal scaffold member. In FIG. 4A, two clips 50 are shown preferably fixedly positioned on each terminating end of the board 10. However, more than two clips 50 may be used. The clips 50 may be attached to board, or integrally formed with the board. As shown in FIG. 4A the clips 50 are “U” or “C” shaped clips extending outw...

Abstract

An improved latchable scaffold board having a board like member with fixed clips or brackets fixedly attached at each end of the board. The brackets are shaped to engage and capture a horizontal scaffold member. The board also has a movable latch at least one end that moves to a latched position, and in the latched position, the movable latch has a portion that is positioned below the horizontal scaffold member, thereby trapping the scaffold board to the horizontal scaffold member.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of U.S. Provisional Application 62 / 531,439 filed Jul. 12, 2017 and PCT Application No. PCT / US2018 / 040571 filed Jul. 2, 2018. The entire contents of the above applications are hereby incorporated by reference as though fully set forth herein.BACKGROUND[0002]A scaffold frame is an interconnected series of horizontal vertical scaffold members and vertical scaffold members used to create a supporting structure for an elevated work surface. The horizontal and vertical scaffold members are generally pipe shaped members (circular or square in cross section, for instance) where the ends of each horizontal scaffold member terminates in connectors that attach to a vertical scaffold members. The connectors can be clamp members (such as in tube and clamp scaffolding, see for instance, FIG. 4) or more complex connectors, such as scaffolding where an end connector is positioned on the end of a horizontal memb...
