Folding rack

DETAILED DESCRIPTION A rack assemblying method according to the present invention comprises the steps of coupling an opening formed through a connector rigid on one of two adjacent horizontal hollow beam members over one of projections which are positioned at vertically spaced locations on one wall of a vertical hollow support member, coupling an opening formed through a second connector rigid on the other horizontal beam member from above the first connector, and retaining the first and second connectors on the projection by suitable means such that the opposite horizontal beam members are pivotable substantially 90.
degree.
in the opposite directions about the projection.
In accordance with the present invention, a folding rack is set up which has non-collapsible vertical hollow support members and collapsible horizontal hollow beam members pivotally connected with the support members through connectors.
Each support member has vertically spaced lugs on each of which connectors on the adjacent beam members are coupled one above the other and pivotally retained thereon as by caulking the head of the lug on the support member.
It is an object of the present invention to eliminate the drawbacks inherent in prior art racks of the collapsible type.
It is another object of the present invention to make a rack readily collapsible by one manual action regardless of the number of its load bearing steps.
It is another object of the present invention to ensure resistivity of a rack to substantial loads and various accidental shocks and impacts and thereby enhance the reliability in use.
It is another object of the present invention to minimize the time and labor necessary for setting up and down a folding rack.
It is another object of the present invention to assemble a light weight, compact folding rack which can be conveniently carried to any desired place.
Other objects, together with the foregoing, are attained in the embodiments described in the following description and illustrated in the accompanying drawings
