Abstract

A storage solution uses wire shelves where the width of the wire shelves can be customized by a user by adding one or more central members between two end members. Thus, the shelving can be installed in one cabinet having a first width, and moved, if desired, to a cabinet of a different width by adding or removing central members from the shelf. Further, a manufacturer can provide a variety of shelf sizes by simply varying the number of central members that are provided. The shelving may be attached at each end to a slide to permit one or more shelves to extend outward from the inside of a cabinet.

3. The modular wire shelf according to claim 1 , wherein each of the first, second, third and fourth engagement members are formed in a U-shape to receive a portion of the wire shelf therein when assembled.

4. The modular wire shelf according to claim 1 , wherein each of the first, second, third and fourth engagement members are formed in a C-shape to receive a portion of the wire shelf therein when assembled.

5. The module wire shelf according to claim 1 , wherein:

the first engagement member engages with a portion of the central member rear rod when the wire shelf is assembled;

the second engagement member engages with a portion of the second side end member rear rod when the wire shelf is assembled;

the third engagement member engages with a portion of the first side end member front rod when the wire shelf is assembled; and

the fourth engagement member engages with a portion of the central member front rod when the wire shelf is assembled.

6. A modular wire shelf assembly comprising:

a central member having a first side outer rod and a second side outer rod;

a first side end member having a first side end member inside rod forming a first removable engagement with the first side outer rod;

a second side end member having a second side end member inside rod forming a second removable engagement with the second side outer rod; and

a plurality of engagement members configured to retain the wire shelf as a planar wire shelf during use thereof, wherein the plurality of engagement members include:

a first engagement member extending from one of a front end or a rear end of the first side end member inside rod, extending beyond the first side end member inside rod, toward the central member;

a second engagement member extending from either (a) a front end of the second side end member inside rod when the first engagement member extends from the rear end of the first side end member inside rod, or (b) a rear end of the second side end member inside rod when the first engagement member extends from the front end of the first side end member inside rod, the second engagement member extending beyond the second side end member inside rod, toward the central member;

a third engagement member extending from either (a) a front end of the first side outer rod when the first engagement member extends from the rear end of the first side end member inside rod, or (b) a rear end of the first side outer rod when the first engagement member extends from the front end of the first side end member inside rod, the third engagement member extending beyond the first side outer rod, toward the first side end member; and

a fourth engagement member extending from either (a) a front end of the second side outer rod when the second engagement member extends from the rear end of the second side end member inside rod, or (b) a rear end of the second side outer rod when the second engagement member extends from the front end of the second side end member inside rod, the fourth engagement member extending beyond the second side outer rod, toward the second side end member, wherein

when assembled, the central member, the first side end member and the second side end member form the planar wire shelf with the first side outer rod and the second side outer rod directly attached, along a respective length thereof, with respective ones of the first side end member inside rod and the second side end member inside rod; and

the first side outer rod of a first one of the central member is configured to removably engage with the second side outer rod of a second one of the central member, such that one or more of the central member are engageable between the first side end member and the second side end member to adjust an overall width of the modular wire shelf.

7. The modular wire shelf according to claim 6 , wherein each of the first, second, third and fourth engagement members engage into U-shaped portions of the modular wire shelf.

8. The modular wire shelf according to claim 6 , wherein:

the central member further includes central member front and rear rods between which the first side outer rod and the second side outer rod extend;

the first side end member further includes first side end member front and rear rods between which the first side end member inside rod extends; and

the second side end member further includes second side end member front and rear rods between which the second side end member inside rod extends wherein
