Appl. No.:

11/443626

International Classification:

E04G 3/32

US Classification:

182113

Abstract:

A quick-connect/disconnect guardrail scaffolding system includes a first scaffold guardrail having a first forked clasp, a second scaffold guardrail having a second forked clasp, and a third scaffold guardrail pivotally coupled to the first scaffold guardrail and releasably coupled to the second scaffold guardrail. A quick-connect/disconnect guardrail scaffolding system includes a scaffold platform and a scaffold guardrail releasably coupled thereto. They cooperate to constrain horizontal separation, constrain vertical separation, constrain relative pivoting in a first direction about a generally horizontal axis, and permit relative pivoting in a second direction about the axis. A quick-connect/disconnect guardrail scaffolding method includes removably engaging a forked clasp of a scaffold guardrail with a flange of a scaffold platform; abutting a generally planar surface of the scaffold guardrail with a generally planar surface of the scaffold platform concurrently with the removable engagement; and releasably coupling the scaffold guardrail to a second scaffold guardrail.

Abstract:

A cart assembly includes a generally M-shaped support member having (i) a first arcuate segment that defines a first apex portion, and (ii) a second arcuate segment that defines a second apex portion. The cart assembly also includes a first wheel base attached to the generally M-shaped support member, and a first caster assembly secured to the first wheel base. The cart assembly additionally includes a second wheel base attached to the generally M-shaped support member, and a second caster assembly secured to the second wheel base. Moreover, the cart assembly includes a handle assembly having (i) a first linearly upstanding segment, and (ii) a second linearly upstanding segment. In addition, the cart assembly includes a cross member connected to both the first linearly upstanding segment and the second linearly upstanding segment. The cart assembly further includes (i) a first brace connected to both the cross member and the first apex portion of the generally M-shaped support member, and (ii) a second brace connected to both the cross member and second apex portion of the generally M-shaped support member.
