Structural connection device for e.g. chevrons of tropical type outdoor umbrella, has lattices individually forming trapezoid modules, and with rigid bars, where lattices are connected by rods, bars or tubes that are fixed inside lattices

摘要

The device has a steel or stainless steel hub comprising two welded/fixed rigid upper and lower discs (2, 3) on which chevrons and purlins of a frame of an umbrella are placed and fixed. Lattices individually form rigid trapezoid modules, and have two flat, square, rectangular or round profiled rigid lateral bars. The lattices are connected by a specific number of rods, bars or tubes that are transversely welded or fixed inside the lattices.
