Abstract
A playground assembly (10) includes a playhouse structure (11) having a plurality of walls (16, 17, 18, 19) and a tower structure (12) having a plurality of walls (29, 30, 31, 32). A tunnel member (15) may be selectively attached between appropriately configured playhouse walls (16, 17) and appropriately configured tower walls (29, 30, 31) by positioning its lug assemblies (91) through notches (92) formed in a selected window (20, 23, 33, 35, 36) and rotating the tunnel member (15) so that the notches (92) traverse ramped surfaces (95) and engage a stop surface (96). Playground assembly (10) also includes a slide (14) which may be selectively attached to appropriately configured playhouse and tower walls (19, 29, 31). To that end, windows (26, 34, 37) in the walls (19, 29, 31) are provided with lugs (109, 110) and the slide (14) is provided with channels (102, 103) which snap over the lugs (109, 110) to attach the slide (14) selectively to one of the walls (19, 29, 31).
