The toy submarine recited in claim 1 wherein said first and said second propellers have at least two propeller blades each.ģ. A toy submarine comprising a hollow, oblong, tubular-shaped, multi-part body simulating a submarine that has buoyancy in water and at least one passage permitting air to exit the hollow interior when the submarine is under water said body having axially adjacent parts forming said hollow interior along a common axis at least a first said body part having a first propeller extending radially therefrom and at least a second said body part having a second propeller extending radially therefrom Ī stretchable member attached to said first and second body parts to assist oppositely directed rotation of said first and second propellers and thereby store energy to cause oppositely directed rotation of said propellers and propel said submarine through water.Ģ. Then, because the plastic that was used for molding the two components is slightly positively buoyant, the toy submarine will slowly surface.ġ. It will quickly travel in a relatively straight line in a forward direction until the energy in the rubber band has dissipated. The two propellers will begin rotate in opposite directions. Then the toy submarine is placed under water and released. To use the toy submarine, the child holds either the tail piece or the head piece and, using a finger, rotates the other propeller until the rubber band is sufficiently twisted. In the assembly, the rubber band is routed through the slot and around the body of the tail piece, then routed through both bodies of the tail and head pieces, and then through the slot and around the body of the head piece. The other ends of the tailpiece and headpiece each have a longitudinal slot. One end of the tailpiece's body mates with one end of the headpiece's body such that their axes are aligned and the bodies are able to easily rotate relative to each other. The bodies of both the tailpiece and the headpiece are hollow and open at both ends. Together they form a counter rotating propeller system. The second molded component is the headpiece and it includes a generally cylindrical body with an integrated propeller that spirals in the opposite direction of the tailpiece propeller. The first molded component is the tailpiece and it includes a generally cylindrical body with an integrated propeller. The plastic is slightly positively buoyant in typical tap water. Two of the components are an injection molded thermoplastic and the other is an ordinary rubber band. A toy submarine consisting of three components.
