Abstract: A foldable play structure is disclosed which includes a first wall unit, a second wall unit, and a first axially latchable hinge. The first hinge includes a first leaf attached to the first wall unit, a second leaf attached to the second wall unit, and a first pintle extending through the first and second leaves along a first axis. The first and second leaves are slidable relative to each other along the first axis between a pivotable position, wherein the first and second leaves may pivot relative to each other about the first axis, and a latched position, wherein pivotal movement of the first and second leaves about the first axis is restrained.

Abstract: A foldable soccer and hockey goal and equipment set is disclosed wherein the goal and the equipment can be conveniently transported and stored in one lightweight and self-contained unit. The goal comprises an inclined net holder having a net attached thereto and being supported by first and second approximately right-triangular upright support members which are hingedly attached to the inclined net holder. The support members are made to be hollow and are provided with filler holes to allow filling with a ballasting material, such as sand or water, to provide stability to the goal when in use. In a closed position, hockey sticks can be placed through rungs situated on each support member to maintain the support members in a folded position and to retain a soccer and hockey ball therein.

Abstract: An apparatus is provided for use in connection with a child's toy which selectively generates a noise. The apparatus includes a chamber within a child's toy for holding a volume of air. Adjacent the chamber is a noise-making member, such as a reed, constructed to vibrate when subjected to a moving air stream. The moving air stream is created when the child sits on the toy and rocks back and forth (i.e., rides the toy). When the child rides the toy, air passes from the chamber and over the noise-making member. Surrounding the noise-making member is a tubular member for directing the air from the chamber around and past the noise-making member. The tubular member has an intake port in fluid communication with the chamber adapted to received air from the chamber and an exhaust port adapted to expel air after it has passed over the noise-making member.
