Abstract

Abstract What is disclosed is a collapsible wire rack characterized by two substantially identical and planar ends for receiving a bottom; a pair of horizontal wire members having at both ends a bent hook eye structure for pivotally receiving respective side end wire members to allow collapsibility; the horizontal wire members being affixed to the rectangularly shaped centerpiece; two substantially identical planar sides; more elongate member defining a more supporting top; four sets arranged one at each end of each side of three shortened vertical wire members, two of each set being bent in a U-shaped configuration for carrying a nut means for screwingly, removably receiving a threaded shaft of a caster; and one of each set having a bent hook structure adjacent its lower end and disposed substantially level with the bent hook structure of the vertical wire member of each end for receiving the bottom; a plurality of substantially horizontal wire members connected with the elongate rectangularly shaped centerpiece and the respective sets adjacent each end for greater strength without interfering with the collapsibility of the wire rack; a plurality of adjustable and removable cross members that each have at each end a bent hook structure for hooking over the top to suspendingly hold in place a computer printout or the like; bottom comprising an elongate rectangularly shaped wire structure adapted to removably fit interiorly of the ends and sides in normal operation and be received within the bent hook structures of the vertical wire members; the wire bottom having sufficient diagonal bracing to impart rigidity to the collapsible wire rack when in place and to be removed to allow the wire rack to be collapsible for shipping, storing and the like. Also disclosed are preferred specific embodiments.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 409 words
A collapsible wire rack for holding computer printout and the like comprising in an operational positional: a. two substantially identical ends, each being substantially planar and formed of covered wire and including: i. a rectangularly shaped center piece having joined together two horizontal wire members and two vertical wire members; ii. a pair of substantially vertical wire members having a bent hook structure at their respective lower ends for receiving a bottom; said vertical wire members being affixed to said rectangular shaped center piece at each crossing of said horizontal wire members and being adapted to removably receive said bottom; iii. a pair of said horizontal wire members having at both ends thereof a bent hook-eye structure for pivotally receiving a respective said end wire member to allow collapsibility, said horizontal wire members being connected with said end; b. two substantially identical sides, each being substantially planar and formed of covered wire and including: i. an elongate rectangularly shaped center piece having joined together two horizontal wire members and two vertical wire members; and having an upper, more elongate member defining a supporting top; ii. two sets arranged one at each end of each side of three shortened vertical wire members, two of each set being bent in a U-shaped configuration for carrying a nut means for screwingly, removably receiving a threaded shaft of a caster; and one of each set having bent hook structure at its lower end and disposed substantially with said bent hook structure of said vertical wire member of each said end for receiving said bottom; said sets of three shortened wire members being connected with said side; iii. a plurality of substantially horizontal wire members connected with said elongate rectangularly shaped center and said respective sets adjacent each end without interfering with the collapsibility of said wire rack; c. a plurality of adjustable and removable cross members that each have at each end a bent hook structure for hooking over said top to suspendingly hold in place a computer printout or the like; d. a bottom comprising an elongate rectangular covered wire structure adapted to removably fit interiorly of said ends and sides in normal operation and be received within said bent hook structure of said vertical wire members; said wire having sufficient diagonal bracing to impart rigidity to said collapsible wire rack when in place and to be removed to allow said wire rack to be collapsed for shipping, storing and the like.
Claim 2
Dependent Claim 409 words
A collapsible wire rack for holding computer printout and the like comprising in an operational positional: a. two substantially identical ends, each being substantially planar and formed of covered wire and including: i. a rectangularly shaped center piece having joined together two horizontal wire members and two vertical wire members; ii. a pair of substantially vertical wire members having a bent hook structure at their respective lower ends for receiving a bottom; said vertical wire members being affixed to said rectangular shaped center piece at each crossing of said horizontal wire members and being adapted to removably receive said bottom; iii. a pair of said horizontal wire members having at both ends thereof a bent hook-eye structure for pivotally receiving a respective said end wire member to allow collapsibility, said horizontal wire members being connected with said end; b. two substantially identical sides, each being substantially planar and formed of covered wire and including: i. an elongate rectangularly shaped center piece having joined together two horizontal wire members and two vertical wire members; and having an upper, more elongate member defining a supporting top; ii. two sets arranged one at each end of each side of three shortened vertical wire members, two of each set being bent in a U-shaped configuration for carrying a nut means for screwingly, removably receiving a threaded shaft of a caster; and one of each set having bent hook structure at its lower end and disposed substantially with said bent hook structure of said vertical wire member of each said end for receiving said bottom; said sets of three shortened wire members being connected with said side; iii. a plurality of substantially horizontal wire members connected with said elongate rectangularly shaped center and said respective sets adjacent each end without interfering with the collapsibility of said wire rack; c. a plurality of adjustable and removable cross members that each have at each end a bent hook structure for hooking over said top to suspendingly hold in place a computer printout or the like; d. a bottom comprising an elongate rectangular covered wire structure adapted to removably fit interiorly of said ends and sides in normal operation and be received within said bent hook structure of said vertical wire members; said wire having sufficient diagonal bracing to impart rigidity to said collapsible wire rack when in place and to be removed to allow said wire rack to be collapsed for shipping, storing and the like.
