专利汇可以提供Aquatic toy专利检索，专利查询，专利分析的服务。并且The invention is a toy for use in a body of water, e.g., a bathtub, a pool or the like. The toy comprises a body typically in the shape of submarine, fish or aquatic mammal, e.g., a whale. The toy normally has a negative buoyancy in water and is pivotally mounted in water with its pivot point located intermediate its ends. Means are provided for feeding air to the lower side of one end of the body. The body is adapted to trap sufficient air to impart positive buoyancy to that end, whereupon the buoyant end rises in the liquid and causes the toy to pivot. The gas trapped in the buoyant end is released when that end has risen to a predetermined level.，下面是Aquatic toy专利的具体信息内容。

权利要求

1. A water toy comprising a body in the shape of a fish or aquatic mammal that normally has a negative buoyancy in water; support means pivotally supporting said body with its pivot located intermediate its ends so that said body can undergo a seesaw motion whereby one of said ends is alternatively higher and lower than the other of said ends: said body being umbalanced so that one end normally falls; said body also being adapted to trap at said one end a quantity of air sufficient to exert a positive buoyancy force to said end and having means for releasing the air trapped at said one end when said end is higher than the other end thereof so as to eliminate the positive buoyancy force exerted by said trapped air, and means for directing air to said one end.

2. A toy according to claim 1 wherein said means for releasing air comprises one or more holes at said one end.

3. A toy according to claim 2 wherein said body also has holes at said other end so that water can flow through said other end.

4. A toy according to claim 1 wherein the pivot axis of said body is located to one side of its center of gravity.

5. A toy according to claim 1 wherein said support means comprises a tubular axLe on which said body is relatively mounted, said tubular axle having at least one hole through which air can be injected into said body.
