发明名称 Playground system
摘要 A playground system including a basic play unit having four corner posts installed upright in a first generally rectangular post formation with the posts at the corners of the formation. A first rectangular frame of the basic play unit includes four side rails, one at each side of the frame and corner brackets connecting the side rails at the four corners of the frame. Fasteners connect the brackets to the posts with the side rails in a generally horizontal plane thereby to provide a rigid, stable structure. Deck boards secured alongside one another to the side rails form decking overlying the frame. At least one adjunct play unit, installed as an adjunct to the basic play unit, includes an anchor portion secured adjacent the basic play unit as by burying in the ground, and a connector portion for connecting the adjunct play unit to the basic play unit. The connector portion is a bracket having first and second legs extending generally at right angles to one another. The first and second legs engage adjoining faces of the basic play unit and are fastened to the basic play unit.
