Modular guard rail for construction scaffolding

A modular guard rail for construction scaffolding, the construction scaffolding having vertical posts and horizontal supporting struts, the modular guard rail comprising:

• a first vertical support member;
• a second vertical support member disposed substantially parallel to and spaced apart from said first vertical support member;
• a plurality of horizontal rails extending between and substantially perpendicularly to said first vertical support member and said second vertical support member and along with said first vertical support member and said second vertical support member defining a guard rail frame;
• each of said plurality of horizontal rails having a major length extending entirely and directly between said first vertical support member and said second vertical support member;
• a first support bracket disposed on a first side of the modular guard rail adjacent said first vertical support member, a second support bracket disposed on a second side of the modular guard rail opposite said first side and adjacent said second vertical support member, a third support bracket disposed on said first side of the modular guard rail adjacent said first vertical support member, and a fourth support bracket disposed on said second side of the modular guard rail adjacent said second vertical support member;
• each of said first support bracket, said second support bracket, said third support bracket and said fourth support bracket comprising two respective leg portions and a respective connecting portion connecting said two leg portions and defining a respective open mouth portion opposite said connecting portion and between said two leg portions of each respective one of the first, second, third and fourth support brackets;
• each of said respective open mouth portion of said first support bracket, said second support bracket, said third support bracket and said fourth support bracket facing a same direction parallel to said plurality of horizontal rails and perpendicular to said horizontal supporting struts of the construction scaffolding;
• said first support bracket and said third support bracket configured to engage a first vertical post of the vertical posts of the construction scaffolding;
• said second support bracket and said fourth support bracket configured to engage a second vertical post of the vertical posts of the construction scaffolding;
• a fifth support bracket disposed on said first side adjacent said first vertical support member;
• said fifth support bracket comprising two leg portions and a connecting portion connecting said two leg portions of said fifth support bracket and defining an open mouth portion of said fifth support bracket opposite said connecting portion of said fifth support bracket and between said two leg portions of said fifth support bracket;
• said open mouth portion of said fifth support bracket, facing a direction perpendicular to said plurality of horizontal rails;
• and
• said fifth support bracket configured to engage a horizontal supporting strut of the horizontal supporting struts of the construction scaffolding.
