Abstract: A vehicle axle joint for a toy vehicle is described and which includes a socket portion; and a ball portion which matingly cooperates with the socket portion, and which defines a gear cavity, and wherein the ball portion may be selectively oriented relative to the socket portions so as to allow hobbyists to construct a multitude of toy vehicles.

Abstract: A construction system is described and which includes a construction element having at least one passageway extending therethrough; a fastener body telescopingly received in the passageway; and a locking member cooperating with the fastener body and which, in a first position, allows the fastener body to be received in the passageway, and in a second position, substantially impedes the removal of the fastener body from the passageway.

Abstract: A construction system is described and which includes a first construction element which has at least one passageway which extends therethrough; a fastener body having a first and a second portion, and wherein the first portion of the fastener body is received in the passageway defined by the first construction element; and a locking member having first and second portions which individually matingly cooperate with the respective first and second portions of the fastener body to secure the fastener body to the first construction element.

Abstract: An endless track comprising a plurality of links which are releasably, rotatably coupled together to form an endless track, and wherein each of the links has a male linking end, an opposite female linking end, and an outwardly facing surface, and wherein the male linking end of a first link releasably couples and decouples from the female linking end of an adjacent second link when the angular relationship between the first and second links as measured between the outwardly facing surfaces thereof lies in a range of greater than about 45 degrees to less than about 110 degrees, and wherein the first and second links freely rotate one relative to the other when the angular relationship between the first and second links lies in a range of greater than about 110 degrees to less than about 270 degrees.
