     BEST MODE FOR CARRYING OUT THE INVENTION 
     In the illustrative embodiment of the invention as disclosed in the drawing, a wheeled table generally designated 10 is shown to comprise a base or lower section 11L having wheels 12 and an upper section 11U. In the illustrated embodiment, the wheels comprise lockable casters of conventional construction. 
     The upper section 11U includes tabletop generally designated 13. The tabletop includes a flat upper surface 14. An edge portion 15 of the tabletop is provided with a pair of elongated openings 16 and 17 spaced inwardly from a peripheral edge 18 of edge portion 15. 
     The peripheral edge of the tabletop is defined by an upstanding wall, or turned flange, having a rounded upper surface 19. The spacing of the openings 16 and 17 from the edge 18 is preselected to permit extension of the fingers of a user&#39;s hand downwardly through the upper surface of the tabletop, with the palm of the user&#39;s hand overlying the rounded surface 19 outwardly from the opening. As a result of the upward extension of the edge wall 18, the palm of the user&#39;s hand is elevated from the flat plane of the surface 14, thereby automatically guiding the user&#39;s fingers downwardly through the opening. 
     As further shown in FIG. 2, the elongated opening 17 is defined by a downwardly curved returned flange, or bead, 20 for providing improved surface contact with the user&#39;s fingers in use. 
     In the illustrated embodiment, the peripheral wall 18 extends fully about the periphery of tabletop 13, as best seen in FIG. 3. Thus, the wall extends at least fully the length of the openings 16 and 17 adjacent thereto. 
     The invention further comprehends provision of a removable pad 21 on the top surface 14. The pad is provided with a pair of openings 22 and 23 substantially congruent with the tabletop openings 16 and 17. The periphery 24 of the pad is substantially congruent with the inner surface of the peripheral wall 18 of the tabletop and, thus, the wall 18 defines means for maintaining the pad against transverse displacement on the tabletop, thereby maintaining the desired alignment of the openings 22 and 23 with openings 16 and 17, respectively. 
     In the illustrated embodiment, tabletop 13 defines opposite ends 26 and 27. End 26 is substantially planar and the longitudinal extent of the elongated openings 16 and 17 are parallel thereto, as shown in FIG. 3. 
     In the illustrated embodiment, tabletop 13 is formed of a rigid material, such as metal or molded synthetic resin. Pad 21 is preferably formed of a resilient material, such as rubber, or a resilient synthetic resin. 
     Tabletop 13 may be provided with at least one additional opening, such as opening 25 for receiving an electrical cord, and pad 21 may be provided with one or more corresponding openings, such as opening 28 aligned with opening 25. Here again, the wall 18 maintains the pad positioned on the tabletop so as to maintain alignment of opening 28 with opening 25. 
     As shown in FIG. 2, the thickness of the pad 21 is substantially less than the height of edge wall 18, so that the user&#39;s fingers may extend downwardly from the user&#39;s palm resting on surface 19 through the aligned openings 22 and 17. 
     In use, an electrical cord for audio-visual equipment or the like may be inserted through the openings 28 and 25 for connection to an outlet assembly 30 which includes a suitable extension cord (not shown) for connecting to an electrical supply. Specifically, the outlet 30 is mounted to one of the four angular legs 32 supporting the tabletop 13 at its four corners. A cord wrap bracket 34 is mounted at the one end 27 of the tabletop for storing the outlet assembly 30 electrical cord. 
     The lower section 11L includes a bottom shelf 36 subjacent a middle shelf 38 interconnected by opposite angular legs 40 connected at each corner. The lower section 11L between the shelves 36 and 38 may be enclosed by suitable wall structure, or doors, as illustrated in phantom. 
     Each of the lower section legs 40 includes a plurality of corner apertures 42 which are equally longitudinally spaced. The apertures 42 are provided for receiving a fastener 44 insertable through an opening in the upper section legs 32. Particularly, the height of the upper section 11U can be adjusted by selectively aligning the apertures in the upper legs 32 with one of the select apertures 42 in each of the corresponding lower legs 40 and inserting the fastener 44 to provide the select height. The upper shelf 38 also includes an aperture 46 through which an electrical cord can be inserted for connection to the outlet assembly 30. 
     Alternatively, if it is desired to have the table 10 of fixed height, then unitary legs of a fixed height could be provided for fixedly mounting the tabletop 13 relative to the height of the lower shelf 36 and middle shelf 38. 
     Thus, the improved wheeled table construction provides for an improved manipulation of the wheeled table by the user&#39;s hand extending through the aligned elongated openings, with the palms of the user&#39;s hands pressing on the edge wall surface 19 so as to direct the user&#39;s hands automatically into the openings. The rounded surfaces 19 and 20 and the resiliency of the pad assure comfortable handling of the cart in moving it along a subjacent surface through the use of the improved integral handle means. 
     As discussed above, the edge wall 18 functions not only to provide a guide for the user&#39;s hand, but also to assure aligned relationship of the openings in the pad with the openings in the tabletop. 
     The wheeled table of the present invention is extremely simple and economical of construction, while providing an improved handle arrangement for facilitated positioning of the tabletop when desired. 
     The foregoing disclosure of specific embodiments is illustrative of the broad inventive concepts comprehended by the invention.
