A sandbox according to the present invention includes a desk having a plurality of legs and defining an open receiving area. The sandbox includes a basin coupled to the desk and extending into the open receiving area, the basin having an area for receiving sand. The basin includes a plurality of sidewalls and at least one sidewall defines a notch. The desk includes a lip extending outwardly from the basin sidewall that defines a notch. The sandbox includes a perforated cover movable between a first configuration covering the lip and a second configuration exposing the lip, the cover defining a plurality of perforations to allow sand to pass through to the lip when at the first configuration. The sandbox includes a drawing board pivotally coupled to the lid and that may be maintained at various angles relative to an imaginary horizontal plane.

The invention claimed is: 1. A sandbox, comprising: a basin defining an interior area for receiving sand, said basin having a floor and a plurality of sidewalls extending upwardly from said floor, said sidewalls having respective upper edges, at least one said sidewall defining a notch extending from a respective upper edge toward said floor and having a lower surface; a lip external to said basin and extending outwardly from said at least one sidewall that defines said notch, said lip contacting said sidewall adjacent said notch lower surface, said lip having an upper edge at a height vertically adjacent said sidewall upper edge; a perforated cover movable between first and second configurations, said cover extending from adjacent said lip upper edge to adjacent said upper edge of said at least one sidewall that defines said notch when at said first configuration, said cover defining a plurality of perforations to allow sand to pass through said cover to said lip when at said first configuration; and wherein said cover is distanced from said upper edge of said at least one sidewall that defines said notch to allow sand to be moved from said lip through said notch and into said basin interior area when at said second configuration. 2. The sandbox of claim 1, further comprising a desk, and wherein: said desk defines said lip; and said basin is coupled to said desk. 3. The sandbox of claim 2, wherein said basin is removably coupled to said desk. 4. The sandbox of claim 2, wherein: said desk includes a drawer having a bottom and defining an open area; a removable pan is positionable in said drawer open area adjacent said drawer bottom; and a perforated grate is positionable upwardly adjacent said removable pan to allow sand to pass from above said grate to said removable pan. 5. The sandbox of claim 4, wherein: said drawer includes a plurality of sidewalls; and at least one said drawer sidewall defines a slot adjacent said drawer bottom to allow said pan to move between said drawer open area and an area outside said drawer. 6. The sandbox of claim 2, further comprising a lid for selectively restricting access to said basin interior area. 7. The sandbox of claim 6, wherein said lid is at least one of slidably and pivotally coupled to said desk. 8. The sandbox of claim 7, further comprising: a drawing board pivotally coupled to said lid; and means for maintaining said drawing board at various angles relative to an imaginary horizontal plane. 9. The sandbox of claim 8, wherein: said basin is removably coupled to said desk; said desk includes a drawer having a bottom and defining an open area; a removable pan is positionable in said drawer open area adjacent said drawer bottom; and a perforated grate is positionable upwardly adjacent said removable pan to allow sand to pass from above said grate to said removable pan. 10. The sandbox of claim 2, further comprising a wheel coupled to said desk for selectively moving said desk, and wherein: said desk includes a plurality of legs; and said desk includes a pocket coupled to a respective leg, said pocket extending toward another respective leg. 11. A sandbox, comprising: a desk having a plurality of legs, a top side, and defining an open receiving area accessible at said top side; a basin coupled to said desk and extending into said desk open receiving area, said basin defining an interior area for receiving sand, said basin having a floor and a plurality of sidewalls extending upwardly from said floor, said sidewalls having respective upper edges, a respective sidewall defining a notch extending from a respective upper edge toward said floor, said notch having a lower surface; wherein said desk includes a lip extending outwardly from said basin sidewall defining said notch, said lip contacting said sidewall adjacent said notch lower surface, said lip having an upper edge at a height above said notch lower surface; and a perforated cover movable between a first configuration covering said lip and a second configuration exposing said lip, said cover defining a plurality of perforations to allow sand to pass through said cover to said lip when at said first configuration. 12. The sandbox of claim 11, wherein said basin is removably coupled to said desk. 13. The sandbox of claim 11, wherein: said desk includes a drawer having a bottom and defining an open area; a removable pan is positionable in said drawer open area adjacent said drawer bottom; and a perforated grate is positionable upwardly adjacent said removable pan to allow sand to pass from above said grate to said removable pan. 14. The sandbox of claim 13, wherein: said drawer has a plurality of sidewalls; and at least one said drawer sidewall defines a slot adjacent said drawer bottom to allow said pan to move between said drawer open area and an area outside said drawer. 15. The sandbox of claim 11, further comprising a lid for selectively restricting access to said basin interior area. 16. The sandbox of claim 15, wherein said lid is at least one of slidably and pivotally coupled to said desk. 17. The sandbox of claim 15, further comprising: a drawing board pivotally coupled to said lid; and means for maintaining said drawing board at various angles relative to an imaginary horizontal plane. 18. The sandbox of claim 17, wherein said lip extends around said basin and said perforated cover extends around said basin when at said first configuration. 19. The sandbox of claim 11, wherein said lip extends around said basin. 20. The sandbox of claim 19, wherein said perforated cover extends around said basin when at said first configuration.
