Collapsible sports goal apparatus
摘要:
Collapsible sports goal apparatus includes a goal base member and a goal net attached to the goal base member. Two flexible, resilient poles extend between the goal base member and the top of the goal net. The poles are bent and exert continuous opposed forces on the goal base member and the goal net top to continuously bias the goal net top away from the goal base member and maintain the goal net in stretched condition and disposed upwardly from the goal base member.
