Arbor construction for on-site assembly

An arbor to be assembled on site without the use of additional fastener elements, comprising:

• a pair of side panels having inner and outer surfaces, each side panel having a vertical U-shaped channel with a base member and two side walls at each edge of said side panels, wherein each U-shaped channel faces outwardly;
• four cap members, each adapted to fit into and over one of said U-shaped channels to close the same;
• a pair of arch members, each having a top edge and a bottom edge, and opposed vertical side edges at each end thereof, wherein the curvature of the top edge has a larger radius then the curvature of the bottom edge;
• and
• a curved roof panel member having opposed end edges and opposed side edges:
• wherein the curvature of said curved roof panel is the same as the curvature of the top edge of each of said arch members;
• wherein there are a plurality of downwardly facing hook members formed in each of said vertical side edges of said arch members, and an equal plurality of cooperating openings adapted to receive said downwardly facing hook members formed in the upper region of each of said U-shaped channels of said side panels;
• and
• wherein there are a plurality of upwardly facing split pins formed in the top edges of each of said side panels and said arch members, and an equal plurality of openings adapted to receive said upwardly facing split pins formed in said end edges and said side edges, respectively, of said curved roof panel;
• whereby said arbor is assembled on site by fitting said arch members to said side members, and by fitting said curved roof panel to the assembled arch members and side panels.
