Abstract
An improved, frictional, interconnecting toy block arrangement having a body means with walls defining a body cavity. The body means of the block is fabricated of two separate body members coupled together along a median plane. Coupling means are provided on the two body members to retain the two body members together. Each of the two body members may be provided with a different appearance, such as, for example, different color, different surface texture, or the like. A female interblock coupling means is provided as an integral part of each of the two body members and the female interblock coupling means comprises a skirt member extending into the body cavity and defining the male interblock coupler means receiving aperture. For the two body members of the body means coupled together the apertures in each are aligned and the inner ends of each of the skirt members within the body cavity are provided with interconnection structure for coupling the inner ends of the skirt members together. One or more toy blocks of a set of toy blocks, are also provided with a male interblock coupler means extending outwardly from one of the walls of the body means and the male interblock coupler means is configured to be frictionally and detachably interconnectable into the female interblock coupling means on another block. The male interblock coupler means are generally fabricated as part of the body means of the block.
