Abstract

A multipurpose floating pillow including an ellipse dish-like lower member having a spherical recess formed on its top surface for receiving an inflatable sac therein. A molded and resilient upper member covers and engages with the lower member. A container may be disposed in a recess formed on the bottom side of the lower member to receive, for example, a weight scale. Pads made of slightly rigid material may be disposed between the inflatable sac and the upper member. The resiliency and softness of the floating pillow can be adjusted through the inflation of the inflatable sac. The floating pillow will therefore not become deformed after long periods of use and may provide different functions on different occasions.

Claims

1. A multipurpose floating pillow comprising a lower member being provided on a top surface thereof with a central spherical recess for receiving an inflatable sac therein, a molded and resilient upper member being disposed above and engaged with said lower member, a container being disposed below said lower member in a recess provided at a bottom side of said lower member, and pads made of slightly rigid material being disposed between said inflatable sac and said upper member;

said inflatable sac being controllably inflated by means of an inflating ball which is connected to said inflatable sac at a front portion thereof by means of an inflating hose;

two gripping rings being symmetrically connected to two lateral sides of said lower member by means of two pulling strings;

both of said inflating hose and said two pulling strings extending to said bottom side of said lower member via through holes formed on said lower member at predetermined positions while said two pulling strings being separately threaded through two substantially diametrically opposite round recesses symmetrically formed at said bottom side of said lower member via a central projection provided at each of said round recesses;

said floating pillow being characterized in an adjustable resiliency which can be controlled through the internal pressure of said inflatable sac by means of said inflating ball and said inflating hose connected to said inflatable sac and thereby, permits said floating pillow to be used in different occasions.

2. A multipurpose floating pillow as claimed in claim 1, wherein said two gripping rings are received in said two round recesses when said gripping rings are not in use, and wherein said lower member is provided with an arcuated groove at a position suitable for accommodating and controlling said inflating hose and said inflating ball when they are not in use.
