摘要：A foldable playpen frame includes socket members which are connectedtogether in such a way that they can be brought from a use position with the sockets atthe four corners of a square, to a storage position with the sockets lying in a straight line.Four floor support members each have vertical portions extending in one of the foursockets. The floor support members extend outwardly to form an X-shaped floorsupport when the sockets are in their use configuration, and lie parallel to each otherwhen the sockets are in their storage position. The vertical frame members are alsopivotally connected to outside ends of the support members so that fewer parts areneeded to form the plate frame.
