Abstract:
Disclosed herein is a device for elevating the legs of a user while sunbathing or otherwise lying down. The device is inserted in pairs into the beach sand or earth, and may be easily and quickly assembled in pairs for transporting and disassembled for use.

Description:
BACKGROUND OF THE INVENTION 
     The object and purpose of the present invention is to provide a leg riser for use while sunbathing which: 
     a. will raise the leg to avoid contact with the ground or sand and to keep dirt, sand and other foreign substances off of the legs of the user; 
     b. will allow rays of the sun to contact portions of the leg which would normally be hidden from the sun due to contact of the legs with the ground or sand; and 
     c. is easily transported and stored.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention is a form of leg riser which may be used while sunbathing to elevate the legs from the earth to prevent contact with the ground or sand to keep sand, dirt or other foreign material from contacting the legs of the human user, while allowing ultraviolet rays from the sun to contact an increased portion of the skin surface of the leg to provide increased tan coverage. The device is used in pairs, with the right foot of the user being placed into one of the risers, and the left foot of the user being placed into the remaining riser. The device may be easily inserted into the ground or sand and provides a rest for the feet and heels of the user. The device is lightweight and provides a locking device so that the device may be connected in pairs when not in use for easy transportation and storage. 
     In the preferred embodiment, as shown in FIG. 1, a generally foot-shaped platform 2 is provided. On the lower portion of the device, a heel rest 4 is connected to the platform 2. The device is inserted into the earth or beach sand 6 with the platform 2 generally perpendicular to the beach 6. A pointed stake 8 is provided for easy insertion into the earth, having a guard 10 at the upper end of the stake 8 to limit the depth of insertion of the stake into the earth or beach, and to keep the platform 2 and heel rest 4 at the proper height. 
     As shown in FIG. 2, the user places a foot 12 against the platform 2, with the heel 14 placed into the rest 4. The foot 12 and leg 16 are then somewhat elevated, reducing leg contact with the ground or beach sand 6. 
     FIG. 4 shows the exact configuration of the stake 8 in the preferred embodiment, having a cross shaped cross section and being tapered along its length (FIG. 2), allowing easy insertion into the ground or sand 6. This configuration also aids in reducing movement of the device within the earth, since the cross shape inhibits movement along either the X-axis or Y-axis when the earth is viewed from above. 
     The leg riser is generally used in pairs, with one leg riser being used for the left foot and one leg riser being used for the right foot. In the preferred embodiment, the device used with the right leg is identical to the device used with the left leg, it being necessary only to rotate the device 180 degrees to use it with one leg as opposed to the other, since the heel rest 4 is present on both sides of the platform (FIG. 2). 
     The leg riser also provides a locking device 18, as shown in FIGS. 5 and 6. The locking device 18 allows the leg riser to be quickly and easily connected to each other for easy transportation and storage in pairs. Two locking devices 18 are fitted to each leg riser in the preferred embodiment. 
     As particularly shown in FIG. 6, each locking device has a male insert 20 and a female receptacle 22. The male insert 20 of one is inserted into the female receptacle 22 of a second unit, with the female 22 of the first unit receiving the male insert 20 of the second. A small raised portion or &#34;nub&#34; 26 of the male insert 20 aids in holding the locking devices together. 
     The device may be made of any suitable material, but particularly lends itself to construction of injection molded plastic. This substance is lightweight, relatively inexpensive in mass production, and allows all of the features of the device to be incorporated into a one piece unit. Wire may be inserted into the platform portion of the plastic material to increase rigidity, and retard breaking.
