Patent ID: 7806283

Claim:
An adjustable shelf assembly, comprising: (a) a central shelf unit, (b) a first extension shelf unit, the first extension shelf unit slidably oriented with respect to the central shelf unit such that the width or depth of the adjustable shelving assembly may be increased by extending and decreased by retracting the first extension shelf unit with respect to the central shelf unit, the first extension shelf unit slidably oriented with respect to the central shelf unit such that retracted portions of the extension shelf unit are located underneath the top surface of the central shelf unit, the first extension shelf unit having a support surface, a front edge, a rear edge, a distal side and a proximate side, the distal side located distal to the central shelf unit relative to the proximate side; and (c) at least one attachment member secured to the adjustable shelf assembly such that when the attachment member is secured to a support structure, the first extension shelf unit may be extended or retracted with respect to the central shelf unit without repositioning the attachment member with respect to the support structure; and (d) a second extension shelf unit, the second extension shelf unit slidably oriented with respect to the central shelf unit such that the width of the adjustable shelving assembly may be increased by extending and decreased by retracting the second extension shelf unit with respect to the central shelf unit, the second extension shelf until slidably oriented with respect to the central shelf unit such that retracted portions of the second extension shelf unit are located underneath the top surface of the central shelf unit, the second extension shelf having a support surface, a front edge, a rear edge, a proximate side and a distal side, the distal side located distal to the central shelf unit relative to the proximate side; and (e) interlocking members formed from portions of the first and second extension shelf units, portions of the interlocking members of the first extension shelf unit interlocking with portions of the interlocking members of the second extension shelf unit when the first and second extension shelf units are retracted with respect to the central shelf unit.
