ABSTRACT:
The invention is concerned with a dismantable joint arrangement comprising three pairs of spaced-apart parallel members, which are arranged relative to one another such that the members of each pair cross the members of the other pairs in abutting engagement therewith and any one pair of members has a respective second pair of members interposed therebetween and a respective third pair of members adjoined thereto and interposed between the members of the respective second pair. At least two dowell-type coupling elements are associated with each pair for positioning the members thereof against those interposed therebetween. The coupling elements are removably inserted in corresponding holes formed at the crossings of the members and are slidably frictionally engaged in the holes so as to be retained therein by frictional force while being slidably removable by the application of manual force. The members of the respective third pair cooperate with the members of the one pair and the respective second pair to stabilize the relative position of these members and the coupling elements associated with the respective second pair releasably lock the members of the respective third pair in place to thereby provide a rigid and secure joint for all the members. The joint arrangement of the invention may be easily dismantled by slidably removing at least one of the coupling elements associated with the respective second pair so as to release at least one of the members of the respective third pair and thereby enable the remaining members to be taken apart.
