    • An adapter for interconnecting hollow toy building blocks having a generally cylindrical primary projection extending outwardly therefrom comprises a housing which is generally square in cross section, having two interconnected pairs of generally parallel sidewalls defining first and second open ends for receiving the blocks to be interconnected. The adapter further includes one generally cylindrical tubular member substantially within the center of the housing, the cylindrical tubular member extending generally parallel to the sidewalls and being supported by at least one flange member extending inwardly from one of the sidewalls, the flange member being generally parallel to and of substantially the same height as the sidewalls. The projections on the blocks to be interconnected are inserted into the space between the sidewalls and the cylindrical tubular member from each end, respectively, so that the sidewalls and cylindrical tubular member cooperate to grip and hold the projection to interconnect the two blocks facing each other.
    • 用于互连中空玩具积木的适配器,其具有从其向外延伸的大致圆柱形的初级突起包括大体上为正方形横截面的壳体,具有限定第一和第二开口端的两个互连的大致平行的侧壁,用于接收待互连的块。 适配器还包括基本上在壳体的中心内的一个大致圆柱形的管状构件,该圆柱形管状构件大致平行于侧壁延伸并由至少一个从侧壁中的一个向内延伸的凸缘构件支撑,凸缘构件大致平行 到达和与侧壁基本相同的高度。 要互连的块上的突起分别从每个端部插入到侧壁和圆柱形管状构件之间的空间中,使得侧壁和圆柱形管状构件协作以夹持和保持突起以将彼此面对的两个块互连 。
