ABSTRACT:
Components of a toy construction set carry undercut male connectors and have elongated grooves for receiving the male connectors to interconnect the components. The grooves have first and second portions. The first groove portions are configured to receive and retain a male connector which has been compressively inserted into such first portions by relatively moving the connector along any one of a plurality of possible insertion paths including a path extending transversely of the longitudinal direction of the associated groove. The second portions are configured to receive and retain a male connector which has been slided longitudinally of the associated groove into engagement with such second portions. In one embodiment, the first groove portions are undercut to a lesser degree than are the second portions. In another embodiment, the first groove portions are not undercut at all but rather are configured to interference fit with a male connector, while the second portions are undercut. In both embodiments, the second portions inhibit to a greater extent than do the first portions any disconnection of the components by relative movement of the components in directions transverse to the length of their respective groove portions.
