DETAILED DESCRIPTION OF THE PRESENT INVENTION

FIG. 1 is a front low perspective view illustrating a first exemplary embodiment of the scaffolding panel system 100, according to a preferred embodiment of the present invention. Vertical scaffold members 101 (one of four labeled) are connected by horizontal scaffold members 103 (one of six labeled) to form a scaffold section. A first floor panel 102 has a male end 106 and a complimentary female end 104, each of which snap fits onto opposing horizontal scaffold members 103. First floor panel 102 has snap fittings 108 (one of four labeled) for diagonal supports, such as diagonal supports 122 (one of four labeled). First floor panel 102 is shown with a flat underside, but this is not a limitation of the invention. First floor panels 102 can be arrayed in sequence across any number of aligned sequential scaffold sections to create flooring of any desired length. As with other panels 110, 120, 130, 140, 200, 400, 900, 1000, 1100, 1200, 1300, and 1400, discussed below, first floor panel 102 is preferably made of molded plastic. In various other embodiments, other materials may be used. For example, and without limitation, aluminum, composites, and steel may be used.

Safety gate panel 110 has two female ends 112, as extending by connecting in sequence in that direction is not generally required. However, the opening of the female end 112 is wide enough to accept a leg of the female end 112, so extension in offset sequence could be accomplished in a special case. The safety gate panel 110 is generally used to prevent falls off an end on a scaffold section. Safety gate 110 connects to the scaffolding by means of snap fit receivers 114 (one of four labeled) receiving a portion of a vertical scaffolding member 101, as shown. Snap fit receivers 114 are preferably molded into the plastic safety gate panel when it is made. In various other embodiments, other materials and methods may be used to meet the functional and cost requirements.

Second floor panel 120 has a male end 126 and a complimentary female end 124, identical to male end 106 and female end 104 of panel 102. The underside 127 of second floor panel 120 features crisscrossing ridges for improved strength and rigidity. Second floor panel 120 has snap fittings 128 (one of four labeled) for diagonal coupling diagonal supports 122 that connect between vertical scaffolding members 101 and second floor panel 120. Second floor panels 120 can be arrayed in sequence across any number of aligned sequential scaffold sections to create flooring of any desired length.

Kick panel 130 has a male end 136 and a complimentary female end 134 each of which snap fits to vertical scaffolding members 101 in a manner similar to safety gate panel 110. Kick panels 130 can be arrayed in sequence across any number of aligned sequential scaffold sections to create kick paneling of any desired length.

Third floor panel 140 is similar to first and second floor panels 102 and 120, but features a skid resistant grid of shallow ridges on the top surface 142. Third floor panel 140 has a male end 146 and a complimentary female end 144.
