Underwater toy

Abstract

A submersible toy whose density is less than water, and whose design and construction allow the toy to glide forward, when released underwater, at a slight upward angle as the toy rises to the surface of the water. The toy includes a single wing, slidable along a channel within the body, that produces variations in movement of the toy depending on the selected position of the wing relative to the body of the toy.

I claim: 
     
         1 . An underwater toy having a density less than water, comprising:
 a body having a left side and a right side and a flat channel extending through the body between the two sides;   a wing member slidably disposed in said channel and extending out from said body on both sides, said wing being selectively moveable away from the body on either side.   
     
     
         2 . The toy of  claim 1 , wherein the channel and the wing are of an arcuate shape. 
     
     
         3 . The toy of  claim 2  wherein the toy further comprises a pin member extending through the body and through the channel in a direction perpendicular to the channel, and wherein the wing includes an arcuate slot through which the pin member extends and relative to which the wing may be moved to different positions along the slot. 
     
     
         4 . The toy of  claim 4 , wherein the slot further comprises a plurality of paired notches spaced apart, one notch of each pair being located opposite the other on the opposing sides of the slot, each of which pairs of notches engages with the pin to temporarily hold the wing in a selected position on the pin member.
