With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved water mattress and anchor apparatus embodying the principles and concepts of the present invention and generally designated by the reference numerals 10 and 10a will be described.

More specifically, the water mattress and anchor apparatus 10 of the instant invention essentially comprises a pneumatic air mattress 11 having parallel first pneumatic chambers 12 of a first length positioned adjacent a second pneumatic chamber 12a, with the second pneumatic chamber 12a positioned in a parallel relationship relative to a second side 14 of the air mattress spaced from a first side 13. A first inner end 15 is spaced from a first outer end 16 having a pneumatic cushion 17 therebetween. A first inflation valve 18 and a second inflation valve 19 effects selective inflation of the chambers 12, 12a and the cushion 17 respectively. A semi-cylindrical cavity 20 extends from an upper distal end of the second pneumatic chamber 12a to the first inner end 15, wherein as illustrated, the first pneumatic chamber 12 is of a first length and the second pneumatic chamber 12a is of a second length less than the first length. The semi-cylindrical cavity 20 is arranged for removably receiving an anchor cylinder 21 therewithin. The anchor cylinder 21 has a lower annular anchor rib 22 spaced from an upper annular anchor rib 23, with the anchor ribs arranged in a concentric relationship relative to the axis of the anchor cylinder 21. A tether line 24 extending from the upper annular rib 23 is tethered to the air mattress 11.

In this manner, the anchor is arranged for reception within the semi-cylindrical cavity 20 for ease of storage and transport of the anchor during periods of non-use.

The anchor, as illustrated in FIG. 3, includes the anchor cylinder 21 of a tubular construction having an externally threaded upper end 25, as well as an internally threaded upper end 26. The upper annular rib 23 is formed as a part of a cap, wherein the cap includes an externally threaded skirt 27 projecting below the upper anchor rib 23, with the externally threaded skirt 27 arranged for threaded inter-engagement with the internally threaded end portion 26. The skirt has internally threaded upper surface 28 spaced above and concentric with the externally threaded skirt 27, with the upper surface 28 positioned interiorly of the upper anchor rib 23 for threaded inter-engagement with the anchor cylinder's forward externally threaded end 25. In this manner, the anchor including a central mandrel 26 fixedly and coaxially mounted to the cap member having a tether line secured thereto, permits the tether line to be wound about the mandrel 29 and positioned within the tubular anchor cylinder 21 for storage of the tether line when mounted to the semi-cylindrical cavity 20.

The apparatus 10a, as illustrated in the FIGS. 4-7, includes an upper semi-cylindrical lid 30 arranged for securement to a lower semi-cylindrical container 31 having hinges 32 pivotally mounting the upper lid 30 to the lower container 31, with a latch 39 arranged for securement of the lid and container together, with the latch and hinges arranged in diametrically opposed positions relative to the container lid structure. The lower container includes a lower container first end wall 33 spaced from a lower container second end wall 35, with a first end wall recess 34 directed through an upper edge of the first end wall 33 to permit the tether line 24 to be directed therethrough, in a manner as illustrated in FIG. 6, during storage of the components within the lid of the container structure. It should be noted that the pneumatic cushion 17 in the apparatus 10a is mounted coextensively about an outer surface of the upper semi-cylindrical lid 30 for use as a cushion structure in conjunction with the mattress 11. An axle 36 is rotatably mounted orthogonally through the first and second end walls 33 and 35 having an axle handle 37 removably mounted relative to the outer distal end of the axle 36 positioned exteriorly of the second end wall 35. A tether line opening 38 is directed through the lower container 31, with the tether line arranged for mounting for a winding about the axle 36 for lifting of the anchor. A handle 40 is mounted adjacent the latch 39 to the lower container 31 for transport of the organization, wherein the container includes a first container cavity 41 spaced from a second container cavity 42 divided by a divider wall 43, wherein the axle is mounted within the first container cavity 41 and the air mattress when deflated is received within the second container cavity 42 for ease of transport of the organization in a unitary manner, as illustrated in FIG. 5. The anchor in this manner may be positioned within the semi-cylindrical cavity 20 when the air mattress is inflated and projecting from the lower container 31, in a manner as illustrated in FIG. 4, or when transport and storage of the organization as a unit is desired, the anchor is positioned within the first container cavity 41 adjacent the axle 36 with the anchor line 24 directed through the first end wall recess 34, in a manner as illustrated in FIG. 6. The anchor is arranged to optionally include anchor legs 44 pivotally mounted and projecting radially relative to an anchor leg plate 45 that is mounted to a lower distal end of a lower tether line 46 that is secured coaxially to the anchor cylinder 21 to the lower anchor rib 22. In this manner, the lower anchor legs 44 and the plate structure, as well as the lower tether line 46 is arranged for removal if such structure is deemed unnecessary in use of the anchor organization and as such this structure may be stored within the first container cavity 41.
