Definitions

  • the present invention is in the field of roof structures for outdoor sunshade structures such as gazebos, rotundas, arbors, kiosks, bandstands, and sheds. All these structures and other related structures will be referred to as gazebos hereafter. More particularly, the present invention is a unique interconnecting roof support system that allows for the construction of two-tier roof structures while at the same time minimizing packaging and shipping costs. Accordingly, the present disclosure makes specific reference to the unique interconnecting roof support system thereto. However, it is to be appreciated that aspects of the present invention are also equally amenable to other like applications, devices, and methods of manufacture.
  • Gazebos are widely used in leisure places such as backyards, squares, beaches, parks, courtyards, and more. Gazebos provide people with a comfortable leisure and cooling space away from direct sunlight or rain and may be built by craftsmen on-site or shipped as parts and assembled on-site. When shipped as parts, the packaging and shipping costs are considerable and care must be taken to ensure that packaging and shipping costs are kept to a minimum.
  • gazebos that utilize a two-tier roof structure are desirable and aesthetically pleasing. Such designs are less susceptible to high wind weather conditions because of the gap that exists between the upper and lower roof tiers. This gap becomes ever more important as over time the square footage of gazebos desired by consumers has grown.
  • packaging and shipping costs for the gazebo have increased as well as increased structural demands on the frame supporting the hip.
