Abstract
An improved deflection-resistant rack designed to reduce the amount of deflection suffered by a rack because of weight being supported therewith. The rack strength achieved by this invention is the result of a design which utilizes each element of the improved rack as an integral member of its spaced double-bar construction. Frequently elements of the improved rack serve in multi-functional capacities within the improved rack design.
Claims8
A deflection-resistant rack comprising:
- a rack member having an endless rectangular structural perimeter member with integral front, rear, left and right members, and a plurality of evenly spaced parallel support members disposed above and rigidly attached to the front and rear members of the structural member;
- and
- a deflection-resistant frame having a plurality of spaced cross-members and a plurality of spaced longitudinal members whereby said spaced longitudinal members are rigidly attached to the bottom of, and in perpendicular relation to, the cross members, the deflection-resistant frame is attached to the bottom of the rack member, the ends of the longitudinal members being attached to the bottom of the front and rear members of the structural member and the ends of the cross-members being attached to the bottom of the left and right members of the structural member such that the longitudinal members of the deflection-resistant frame are in parallel relation to the support members, the ends of the cross-members are bent downwardly and outwardly such that the top edges of the body of the cross-member are in substantially the same plane as the bottom edges of the support member, the cross members being rigidly attached to the support member whereby to form a space double-bar deflection-resistant support structure.
