Abstract: A toy truck having a crane arm, comprising multiple telescopic components to form a crane extension mechanism. The crane arm extension mechanism includes a crane arm that is capable of telescopically extending based on the air pressure manually provided to fill telescopic members of the crane arm. To telescopically extend the crane arm, a crank is rotated which causes an air pump to pump air into the crane arm. As the air pressure in the crane arm increases, the crane arm telescopically extends.

Abstract: A system for easy, quick and inexpensive coupling of the shells of a toy housing, without screws fasteners, comprising a first shell having an inside T-shaped projecting member with side edges of the arms of the T being captured between a set of apertures located in a pair of parallel, opposed and resilient walls of the other housing shell, such that pressing the two shell pieces together causes the edges of the arms of the T shaped member to cam outwardly the otherwise parallel walls of the other shell until the edges are captured in apertures in the side walls of the second shell member.

Abstract: A water-based drawing surface and a toy employing same are disclosed. The drawing surface includes a plastic substrate layer and a fabric layer adhered to the plastic substrate layer. A substantially water-resistant layer is applied to the fabric layer, and an ink layer is applied to the substantially water-resistant layer. The ink layer includes ink imprinted thereon, the ink being water-soluble when initially applied to the substantially water-resistant layer and insoluble after the ink has dried on the substantially water-resistant layer. When water is applied to the ink layer after the ink has dried thereon, the ink layer darkens in the shape of the water applied thereto. The ink is preferably screen-printing ink and it is preferably hand brushed onto the fabric layer.

Abstract: A portable playpen/mattress for babies is described. The playpen includes a flexible base and a plurality of substantially open walls all consecutively attached to each other. The walls are attachable to the base substantially perpendicular to the base. When the walls are attached to the base, the playpen is in an erected configuration, and when the walls are detached and folded one on top of another, the playpen is a collapsed configuration. The base is attachable to the walls in two configurations. When the corners of the base are curled around the leg portions of the walls, the base is in a rimmed configuration, and when the leg portions are directly attached to an upper surface of the base, the base is in a flat configuration. A reversible roof is selectively attachable to the walls. An outer cover is adapted to enclose the base and the walls in the erected configuration.
