Claim:
A receiver and retainer assembly, to facilitate positioning a cross-member on a support of predetermined height, length and width and which within the predetermined height, length and width configures a three dimensional, 3-D space, the cross-member being of selected length and width and carrying at each of its respective ends an attacher of plate material of predetermined thickness and with each such attacher having a slot of selected size extending inwardly from an edge of the attacher a selected amount so that each such attacher appears to be hook-like in configuration; the receiver and retainer assembly comprising: a. at least one clamping member configured to be positioned on the support, at a selected position intermediate ends of the support and without having to be applied thereto over an end of the support, to facilitate securing the cross-member to the support; b. at least one retainer physically attached to and extending directly from said clamping member for receiving and retaining one of the ends of the cross-member; and c. said retainer including at least one slot open at its top and which is sized and configured to receive and position the attacher from one of the ends of the cross-member so that said slot receives the attacher and the slot of the attacher is received by the retainer and so that the attacher can only be separated from the retainer by movement substantially in the direction opposite to the direction the attacher was moved when the attacher was inserted into the retainer, there being substantially no other relative movement between the retainer and the attacher; d. said retainer facilitating positioning the cross-member on the support and within the 3-D space configured by the support.
