A serving cart comprising a serving top, a base including wheel means, vertical supports extending between said base and said top, a carrying shelf for bottles and containers positioned between said base and said top, and means for vertically adjusting said shelf relative to said top, said top having a plurality of separate openings defined therethrough for selective projection of the bottles and containers through said openings for direct access thereto when the shelf is vertically adjusted upward toward said top, said shelf including interconnected parallel upper and lower panels, said lower panel comprising a support surface for the bottles and containers, said upper panel having a series of openings therein receiving, positioning, and stabilizing the bottles and containers supported on the lower panel and projecting upwardly through the upper panel openings, said means for vertically adjusting said shelf comprising self-contained power means, including a battery powered motor, mounted on said base, and a control system extending from said power means to said shelf for a selective vertical movement of the shelf in response to activation of the power means, said control system includes an elongated shaft rotatably mounted on said base and driven by said motor, said shaft extending centrally and longitudinally of said base, said shaft having opposed end portions, a pair of flexible members affixed to each end portion of the shaft, each pair of flexible members, outward of the corresponding end of the carrying shelf, extending vertically to and about a series of pulley members affixed respectively to the undersurface of the serving top and the corresponding end of the carrying shelf, whereby rotation of the elongated shaft in a first direction will effect a winding of the flexible members thereon and a corresponding elevation of the carrying shelf, a rotation of the shaft in the opposite direction will effect an unwinding of the flexible members therefrom and a gravitational lowering of the carrying shelf, said serving cart further including an extension leaf hingedly mounted along each edge of the serving top and selectively moveable between a first position overlying the serving top, and a second position pivoted upward and outward so as to generally parallel the serving top, and means for releasably supporting each leaf in its outwardly swung position comprising a support bar, and a track mounted beneath the serving top and receiving said bar for a selective extension thereof outward so as to at least partially underlie the outwardly positioned leaf. 2. The serving cart of claim 1 including low upwardly projecting rims provided on said top about the openings defined through the top.
