发明名称 Compact folding sports goal
摘要 A collapsible sports goal that can be selectively configured between an erect configuration and a folded configuration. The sports goal has six frame elements. Each of the frame elements has two opposite ends. Each end of the frame elements connects to the end of another frame element using six connector joint assemblies. Each of the joint assemblies receives and interconnects a different two of the six frame elements. Each of the connector joint assemblies contains a hinge joint that enables the frame elements connected to each of the six joint assemblies to rotate about said hinge joint between a parallel configuration to a perpendicular configuration. When all of the connector joint assemblies are in their perpendicular configuration, the sports goal is in its fully erect configuration. Conversely, when all of the connector joint assemblies are in their parallel configuration, the sports goal is in its fully folded configuration.

主权项 1. A collapsible sports goal comprising: six frame elements, wherein each of said frame elements has two ends; six connector joint assembles that interconnect said six frame elements at said ends of said six frame elements, wherein each of said joint assemblies receives and interconnects two separate frame elements from said six frame elements, wherein each of said connector joint assemblies has a first leg with a first open ended shaft, and a second leg with a second open ended shaft, wherein said first open ended shaft and said second open ended shaft receive said two separate frame elements, and wherein each said second leg has a hinge plate that extends laterally from said second open ended shaft, wherein said first open ended shaft connects to said hinge plate at a hinge joint that enables said two separate frame elements connected to each of said six joint assembles to rotate about said hinge joint between a parallel configuration and a perpendicular configuration, and a locking pin having a keyed body in each of said connector joint assemblies that extends into said hinge plate between said first open shaft and said second open shaft, said locking pin being selectively positionable between a first position and a second position, wherein when in said first position, said first open ended shaft and said second open ended shaft are free to rotate about said hinge joint between said parallel configuration and said perpendicular configuration, and wherein when in said second position said first open ended shaft and said second open ended shaft are locked in said perpendicular configuration.
