ABSTRACT:
A building element for use in constructing a play structure with similarly shaped elements is disclosed. The building element has a rectangular base provided with longitudinal slots in the center of each lateral side. Each slot extends inwardly by distance equal to one half of the distance from a respective corner of the base to an adjacent edge of a respective longitudinal slot. At least one lateral slot is also provided along each longitudinal side, the lateral slots are sized the same as the longitudinal slots and spaced from a respective corner or each other by the same distance which the lateral slots are spaced from a respective corner. A peripheral flange extends perpendicular from the back face of the base around the periphery of the back face and slots. The outer edge of the peripheral flange is spaced from the front face by a distance nominally equal to the width of the slots. A raised portion is also provided which extends perpendicularly from the back face of the base by the same distance as the peripheral flange and which includes a rest area which is spaced inwardly along the back face from each of the slots by a distance less than the length of each slot. Preferably, a longitudinal rib member and a lateral rib member extend between respective longitudinal slots and lateral slots. In addition, reinforcing ribs also extend between adjacent slots and the corners of the slots are reinforced. In the preferred embodiment, the building element is integrally formed of a foamed polyethylene or foamed polypropylene.
