A mechanical joint for a collapsible structure is formed from a hollow structure of material shaped to bring opposite sides of the external walls to form a socket. The socket is configured to provide a snap fit with a moveable member. A flexible member is positioned in the socket and attached to the moveable member to control the latter for placement in and out of the socket. The flexible member may also twist to permit the moveable member to be located in any position necessary to allow the moveable member to be engaged in the socket or disengaged from the socket, reducing the need for precise component tolerances. The joint is useful in structures that have multiple configurations, for example, structures such as portable game goals, where it is desirable for the structure to collapse from an erect position for game play into a collapsed configuration for transport. |
