DETAILED DESCRIPTION

Referring to FIGS. 1-3, a first embodiment of a moat-making kit is shown. In that embodiment, the moat-making kit comprises a stake 1, a shovel 2, a boat 3, a liner 4, two stake rings 5, and a string or cord 6. The two rings 5 are attached at opposite ends of the cord 6, for example by a knot on the cord 6. The two rings 5 are connectors for connecting one end of the cord 6 to the stake 1 and the other end of the cord 6 to the shovel 2. Both the stake 1 and the shovel 2 include corresponding connectors. For example, the stake 1 includes a post 1 a with an enlarged diameter head 1 b for connecting with one of the rings 5. The shovel 2 includes at least one hook 2 a for connecting with the other ring 5, and preferably two hooks 2 a, 2 b on opposites sides of the shovel 2 to facilitate use by both right- and left-handed individuals.
It is contemplated that other embodiments could include various combinations of the above-mentioned or other equivalent components. For example, the rings 5, post 1 a and head 1 b, and hooks 2 a, 2 b, can be replaced with simple screws and nuts or a ball that snaps into a recess on the top of the stake 1 and/or shovel 2. As another example, the rings 5 need not be used and the cord 6 is pivotally attached to the stake 1 by way of crimped portions of cord 6 such that a portion of cord 6 is crimped together with another portion of cord 6 to form a loop around the post 1 a of stake 1. In this example, the crimped portion of cord 6 allows for the shovel 2 to be moved in a generally circular path around the stake 1. The cord 6 can be a flexible material like string or a more rigid one like plastic. The cord 6 could also comprise 2 or more pieces of dowel that attach together with a 2-sided female component or 3 flat pieces of plastic that attached together with wing nuts. The cord 6 could also be permanently attached to the stake 1 and/or the shovel 2, and could wrap around the stake 1 and/or shovel 2 for storage, or retract into one or both the stake 1 and shovel 2. The liner 4 could be made of any flexible, nonporous material, such as vinyl, plastic or rubber. Preferably, the liner 4 is thin so it can fold up easily and store compactly. The liner 4 could be completely flat and conform to the shape of the channel when installed, or it could be manufactured with a bottom and sides giving it a more sturdy body. Alternative designs for the shovel 2 could include a handhold in the blade instead of a handle.
The moat-making kit is designed to be used at an outdoor recreational area, such as a beach or a pool, where a porous medium such as sand 7 is provided. When used at a beach, the moat-making kit is used by first choosing a location that is near the water, but beyond the reach of the waves. Next, an area large enough to accommodate the liner 4 is smoothed out. Preferably, the dry sand on top should be removed, and the moist sand just below should be smoothed. Moist sand holds its shape better and is easier to work with.
One end of the cord 6 is attached to the stake 1, which is placed in the center of the smoothed-out area and inserted into the sand, leaving the top two inches of the stake 1 exposed. The shovel 2 is attached to the opposite end of the cord 6. Generally, during use of the moat making kit, cord 6 is connected to stake 1 at one end and connected to shovel 2 at another end. Generally, the cord 6 is pivotally attached to stake 1 such that shovel 2 can be moved in a uniform circular motion with respect to the stake.
The shovel 2 is pulled away from the stake 1 such that the cord 6 is pulled taut, but care should be taken to avoid displacing the stake 1. Sand 7 is progressively removed using the blade of the shovel 2 until the proper depth is reached as marked by a depth gauge 2 c on the shovel. As sand 7 is removed, the shovel 2 is moved around the stake 1 in a circular path, keeping the cord 6 taut, to form an annular moat. The depth gauge 2 c can be any indication on the shovel such as a raised line or groove. The removed sand is generally placed outside the circle so that the removed sand does not interfere with the cord 6 as the shovel 2 moved in a circular motion with respect to the stake 1. In another embodiment, the removed sand can be placed in the center of the moat for use later when building a sandcastle. However, in this embodiment, the sand inside the center of the circle can interfere with movement of the cord 6 as the shovel is moved. Accordingly, it is preferred that the removed sand is placed outside the circle and not inside the circle. When finished removing the sand, the shovel 2 can be pulled backwards in the channel to smooth out the surface of the channel.
Next, the liner 4, which can be made of any impermeable material, such as plastic, is placed in the channel. For instance, the material is impermeable to water. The liner 4 should be firmly pushed into the moat to prevent unwanted displacement during play. Once the liner 4 is in place, the shovel 2 can be pulled backwards in the moat to smooth out the liner 4 and water can be poured into the center of the moat. Care should be taken to ensure no water gets underneath the liner. The moat is now finished and ready for play.
Because the blade of the shovel 2 is provided with a depth gauge 2 c and a shape and dimensions that correspond to the shape and dimensions of the liner 4, proper use of the above-described method results in a near-perfect annular channel that matches the shape and dimensions of the liner 4. Accordingly, shovel 2 has a shape and dimension that corresponds to the shape and dimension of liner 4 such that proper use of shovel 2 results in a snug and easy fit for the liner 4 into the moat.
Although the inventions described and claimed herein have been described in considerable detail with reference to certain embodiments, one skilled in the art will appreciate that the inventions described and claimed herein can be practiced by other than those embodiments, which have been presented for purposes of illustration and not of limitation. Therefore, the spirit and scope of the claims below should not be limited to the description of the embodiments contained herein.
