Abstract: A play enclosure is disclosed including an elongated conduit having a plurality of light admitting pinpoint apertures. The conduit is curved and has a diameter large enough to allow children to crawl through. A strobe light is suspended above the conduit. The pinhole apertures admit beams of light from the strobe light, which cast visually stimulating patterns on the internal wall of the conduit.

Abstract: A play apparatus is disclosed for climbing and crawling that is especially suitable for indoor play grounds. In one embodiment, the play apparatus includes a frame having a plurality of spaced apart netting supports extending across the width of the frame. The netting supports are located at least two different heights, and netting spans the netting supports to define at least one climbing and crawling pathway thereover.

Abstract: An article of play apparatus is claimed having an elevated platform and two inclined surfaces which extend downwardly from the elevated platform. Cylindrical ridges traverse the first inclined surface, and allow children to climb up the first surface toward the elevated platform. Children can then descend the second inclined surface, which includes adjacent padded rollers over which children can slide or crawl. In one embodiment, the first inclined surface is planar, but has a number of padded cylindrical wells suitable for receiving the hands and feet of a child.

Abstract: A play apparatus for use by children is provided having a base which includes horizontal spaced apart obstacles, legs for supporting the base on a generally flat supporting surface, such as a floor, and a tunnel structure positioned over the base. The tunnel structure has openings which serves as entrances and exits and which define a pathway through the play apparatus. The legs support the obstacles above the floor so that a child must step over the obstacles as he walks through the play apparatus. The tunnel structure is located at a predetermined height over the base. The height chosen requires a child to stoop or bend over while walking through the play apparatus. In one embodiment, the play apparatus has an additional tube attached to and extending through a side wall of the tunnel. The tube provides an additional opening through which a child may crawl. This embodiment has six obstacle members carried by the base.
