## Background
BACKGROUND OF THE INVENTION
This invention relates generally to sandboxes and, more particularly, to a sand play station that may be used indoors, is portable, and may be used to hold other items.
Sand has always been a popular source of entertainment for young children. Both beaches and sandboxes enable kids to interact with one another or to play quite independently. In the past, sandboxes have typically been found outdoors, making playing in the sand difficult or even impossible on a rainy day or during the wintertime. Even on a clear or warm day, however, children must choose between playing outdoors in the sand or indoors with colors, markers, or other typically indoor activities.
Various devices have been proposed in the art for holding sand for play indoors. Although assumably effective for their intended purposes, the existing and proposed devices do not effectively maintain the sand within a basin, do not provide selective and convenient use of the sand, colors, markers, and the like, or are not effectively portable.
Therefore, it would be desirable have a sandbox that effectively maintains sand within a main basin and that provides for efficient cleanup of sand. Further, it would be desirable to have a sandbox that provides for selective play with sand or coloring or marking materials. In addition, it would be desirable to have a sandbox that is portable and movable.
SUMMARY OF THE INVENTION
Therefore, a sandbox according to the present invention includes a basin defining an interior area for receiving sand and having a floor with a plurality of sidewalls extending upwardly from the floor. At least one sidewall defines a notch. The sandbox includes a lip external to the basin and extending outwardly from the sidewall that defines a notch, the lip contacting the sidewall adjacent a lower surface of the notch.
The sandbox includes a perforated cover that is movable between first and second configurations, the cover extending from adjacent the upper edge of the lip to adjacent an upper edge of the sidewall that defines the notch when at the first configuration. The cover defines a plurality of perforations to allow sand to pass through the cover to the lip when the cover is at the first configuration. This allows sand to be efficiently collected for return to the basin.
The sandbox also includes a desk, the desk defining the lip and the basin being removably coupled to the desk. The desk includes a drawer and a removable pan is positioned in the drawer. A perforated grate is positionable upwardly adjacent the removable pan to allow sand to move from above the grate into the removable pan. This allows sand to be efficiently collected and removed from the drawer. A drawing board is pivotally coupled to the lid and it may be maintained at various angles relative to an imaginary horizontal plane.
Therefore, a general object of this invention is to provide a sandbox for holding sand in an indoor environment, that prevents sand from spilling, and that provides for efficient cleanup of sand.
Another object of this invention is to provide a sandbox, as aforesaid, that selectively provides for play with sand or a drawing board for use with colors or markers.
Still another object of this invention is to provide a sandbox, as aforesaid, in which the sandbox basin is removable.
Yet another object of this invention is to provide a sandbox, as aforesaid, that is portable and movable.
A further object of this invention is to provide a sandbox, as aforesaid, that includes a desk with drawers for holding items.
A still further object of this invention is to provide a sandbox, as aforesaid, that is easy to use and cost-effective to manufacture.
Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A sandbox 100 according to the present invention will now be described in detail with reference to FIGS. 1 through 6 of the accompanying drawings. More particularly, a sandbox 100 according to the current invention includes a basin 110.
The basin 110 defines an interior area 112 for receiving sand or another substance (e.g., water), and the basin 110 has a floor 113 and a plurality of sidewalls 114 extending upwardly from the floor 113. Each sidewall 114 has an upper edge 114a, and at least one of the sidewalls 114 defines a notch 115 that extends from a respective upper edge 114a toward the floor 113. Each notch 115 has a lower surface 115a. 
As best shown in FIG. 2b, a lip 120 may be external to the basin 110 so that the lip 120 extends outwardly from the sidewalls 114 defining the notches 115. The lip 120 may contact the sidewalls 114 adjacent the lower surfaces 115a of the notches 115, and the lip 120 may have an upper edge 120a at a height vertically adjacent the sidewall upper edge 114a or at least at a height that is above the lower surfaces 115a of the notches 115.
A perforated cover 130 may be movable between a first configuration 130a (FIG. 6) covering the lip 120 and a second configuration 130b (FIG. 1) exposing the lip 120. When at the first configuration 130a, the cover 130 may extend from adjacent the lip upper edge 120a to adjacent the upper edge 114a of the sidewall(s) 114 defining the notch(es) 115. As shown in FIGS. 1 and 6, the cover 130 may define a plurality of perforations to allow sand to pass through the cover 130 and to the lip 120 when the cover 130 is at the first configuration 130a. When at the second configuration 130b (FIG. 1), the cover 130 is distanced from the upper edge 114a of the sidewall(s) 114 defining the notch(es) 115 to allow sand to be moved from the lip 120 through the notch(es) 115 and into the basin interior area 112. In this manner, sand that may have accumulated in the lip 120 may be returned to the basin 110. The lip 120 and/or the cover 130 may extend around the basin 110 when the cover 130 is at the first configuration 130a. 
As shown throughout the drawings, the sandbox 100 may include a desk 140. The desk 140 may define the lip 120, and the basin 110 may be coupled (either permanently or removably) to the desk 140. The desk 140 may have a plurality of legs 142 and a top side 143, and the desk 140 may define an open receiving area 145 accessible at the top side 143. The basin 110 may extend into the desk open receiving area 145 as shown in FIG. 1, for example. Though not shown, the plurality of legs 142 may be interconnected, to form a pedestal, for example.
The desk 140 may include a drawer 146 that has a bottom 146a, a plurality of sidewalls 146b, and defines an open area 146c, as shown in FIG. 3. Of course, the desk 140 may include a plurality of drawers, each having a substantially similar construction. A removable pan 147 may be positionable in the drawer open area 146c adjacent the drawer bottom 146a, and a removable perforated grate 148 may be positionable upwardly adjacent the removable pan 147 to allow sand to pass from above the grate 148 to the removable pan 147. A respective drawer sidewall 146b may define a slot 146d adjacent the drawer bottom 146a to allow the pan 147 to move between the drawer open area 146c and an area outside the drawer 146. The desk 140 may additionally or alternately include pocket 149 (FIG. 4b) coupled to a respective leg 142 and extending toward another respective leg 142, and/or a wheel(s) 141 (FIG. 1) may be coupled to the desk 140 for moving the desk 140.
A lid 150 may be included for selectively restricting access to the basin interior area 112. The lid 150 may be pivotally and/or slidably coupled to the desk 140, such as through a pivoting member 152 and/or a sliding member 154 as shown in FIG. 5b. A drawing board 155 may be pivotally coupled to the lid 150 as shown in FIGS. 1, 2a, and 5a to provide a user with a flat surface for drawing or otherwise creating artwork. Means for maintaining the drawing board 155 at various angles relative to an imaginary horizontal plane may be included. More particularly, sliding or telescoping members 156 (FIG. 1) or other appropriate fasteners may be used to angle the drawing board 155.
In use, sand may be placed in the interior area 112 of the basin 110, and a child may reach into the basin 110 or otherwise play in the sand. Sand that is strewn outside the basin 110 may pass through the perforated cover 130 and onto the lip 120. A user may remove the cover 130 and sweep the sand through the notch(es) 115 and into the basin interior area 112 as desired. Toys or other implements may be held in the drawer 146 and/or the pocket 149. The removable pan 147 may be pulled through the drawer slot 146d or otherwise separated from the drawer open area 146c and emptied as desired. The desk 140 may be selectively moved using the wheel(s) 141. The lid 150 may selectively cover the basin interior area 112 (and therefore restrict access to any sand contained therein) as discussed above, and the drawing board 155 may be used as described above.
It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
