Abstract

Abstract A modular toy (1) allowing easy assembly for children has a frame (3), a bridge (23), and a hub assembly (27) as primary features. The frame and bridge have slots (5, 6), which in turn have fasteners (7). The hub assembly snaps or otherwise removably mounts in the slots. This allows toy pieces, such as gears (57, 59), to be placed on the hub assemblies. The gears can be rotated on the hubs and effect movement of other gears attached to other hubs. The slots are generally equally spaced so that children have an easy method of effecting the movement.
