ABSTRACT:
A hinged platform assembly includes a platform having an end member with a lobed surface on one side thereof and a relatively flat surface on another side thereof. A socket assembly is provided for receiving the end member and enabling the member to turn about an axis within said socket means. The socket assembly includes an opening therein for enabling insertion of the member into said socket means at one angular relationship between said member and the socket assembly and preventing separation of the member and the socket assembly at all other angular relationships therebetween. The socket assembly further includes opposing surfaces for preventing turning of the member within the socket assembly past a selected angle therebetween, thus allowing the platform to support heavy loads without the need of additional components or struts of any kind.
