Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to anchor devices, and more particularly pertains to a new and improved anchor device designed for use in lakes, ponds, and swimming pools for securing inflatable rafts and cushions in a desired location. Individuals sunbathing on inflatable rafts and cushions are prone to drift from their desired location because of wind and water currents. In swimming pools, this results in the bumping of the rafts or cushions into the walls of the pool or into other individuals. In a lake or pond, this drifting can be dangerous. Also, individuals sunbathing on such inflatable rafts and cushions require a storage area for their keys and other personal belongings and also require a beverage container holder. In order to solve all of these problems, the present invention provides an anchor device which includes a compartmentalized tray having an adjustable sunshade and a plurality of storage compartments. It is safe to use in all types of pools and has no sharp edges to cut or perforate plastic liners. On the beach or poolside the anchor device will hold blankets, towels or mats in place. 
     2. Description of the Prior Art 
     Various types of anchor devices are known in the prior art. A typical example of such an anchor device is to be found in U.S. Pat. No. Des. 181,102, which issued to F. Kurt et al on Oct. 1, 1957. This patent discloses a generally cylindrical mooring buoy having an anchor rope attaching loop and a central flag staff. U.S. Pat. No. Des. 191,726, which issued to J. Divietro on Nov. 7, 1961, discloses an anchor having a conically tapered body portion with a plurality of radially extending projections. U.S. Pat. No. Des. 195,796, which issued to J. Christiansen on July 30, 1963, discloses an inflatable flag for use by divers. The device includes a strap attaching loop and a generally rectangular flag. U.S. Pat. No. Des. 203,485, which issued to C. Shepherd on Jan. 11, 1966, discloses a buoy having a generally frustoconical body portion provided with a pair of attaching loops at opposite ends thereof. U.S. Pat. No. Des. 203,525, which issued to C. Hutton on Jan. 18, 1966, discloses a boat anchor having a generally rectangular body portion provided with a plurality of spaced radial projections. An attaching loop for securement of an anchor rope is connected at one end of the rectangular body portion. 
     While the above mentioned devices are suited for their intended usage, none of these devices provide a suitable restraint for use by sunbathers on inflatable rafts and cushions. Additionally, none of the aforesaid anchor devices provide a circular compartmentalized storage tray having an attached adjustable sunshade. Inasmuch as the art is relatively crowded with respect to these various types of anchor devices, it can be appreciated that there is a continuing need for and interest in improvements to such anchor devices, and in this respect, the present invention addresses this need and interest.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved anchor device embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the first embodiment 10 of the invention includes a cylindrical tray 12 which has a raft tether rod 14 which spans a semicircular recess 16 formed in the outer wall of the tray 12. A raft or inflatable cushion may be tethered to the rod 14 by a short length of rope or cord. The tray 12 is designed to float on the surface of a body of water, adjacent an individual sunbathing on an inflatable raft or cushion. The tray 12 is divided into a plurality of compartments 18, 30, 34 and 42 by a plurality of radially extending circumferentially spaced vertical dividing walls 20, 22 32, and 40. A central beverage holder 26 is formed by an upstanding cylindrical wall 28. The radially extending dividers 20, 22, 32 and 40 extend between the cylindrical wall 28 and the outer cylindrical wall of the tray 12. A second tether rod 36 spans a semicircular recess 38 provided diametrically opposite the first semicircular recess 16. The second tether rod 36 is designed for securement of an anchor rope to the tray 12. The anchor rope is attached to an anchor on the bottom of the body of water on which the tray 12 is floating. Thus, the tray 12 and attached anchor serve to restrain an inflatable raft or cushion in a desired location. A cylindrical socket 24 is provided for mounting an adjustable sunshade on the tray 12. The cylindrical socket 24 is formed in the radially extending vertical dividing wall 22. 
     In FIG. 2, a side view of the tray 12 is provided. 
     In FIG. 3, a transverse cross sectional view illustrates the constructional details of the compartmentalized tray 12. 
     In FIG. 4, a plan view is provided which illustrates the adjustable sunshade for use with the anchor device 10 according to the first embodiment of the present invention. The sunshade includes a flat circular disc 44 of a tinted or opaque material which is secured by a clamp 46 to a flexible gooseneck 48. The gooseneck 48 terminates in a cylindrical plug 50 dimensioned to be received within the socket 24 on the tray 12. The plug 50 may be rotated within the socket 24, to adjust the position of the sunshade 44. The flexible gooseneck 48 allows the sunshade 44 to be bent in any desired direction. 
     In FIG. 5, a transverse cross sectional view illustrating the sunshade 44, is provided. 
     In FIG. 6, a top view of a spoon type anchor for attachment to the tray 12 is provided. The anchor has an elongated narrow shank 52 provided with a circular aperture for reception of an anchor rope. The anchor rope will then be attached to the anchor tether rod 36 on the tray 12. The anchor shank 52 is integrally formed with an enlarged concave body portion 56 which has a generally spoon shaped configuration. The body portion 56 tapers to a narrow concave hook portion 58 which is bent along a radius toward the shank 52. In use, the hook 58 and concave body portion 56 of the anchor will dig into the earth at the bottom of a lake or pond. Thus, the anchor serves to restrain the tray 12 and attached inflatable raft or cushion in a desired location.
