- Target based games and target based sporting activities are extremely popular with both youths and adults. Various types of target based games are known. Many such target based games and sporting activities are centered around hunting type weapons such as guns or bow and arrows which require adult supervision. Other such target based games and sporting activities involve video games which provide very limited physical exercise.
- Also popular are recreational aquatic activities. Aquatic activities including, but not limited to, pool activities are known to provide children with an increased level of physical exercise. While many aquatic activities are known that involve balls, target based aquatic activities that would appeal to children and provide important physical exercise are very limited.

The arrangement for imparting propulsion further includes a first spring for biasing the external plunger to the unloaded position indirectly through the internal plunger. The arrangement for imparting propulsion further includes a triggering arrangement for selectively releasing the external plunger from the loaded position. The triggering arrangement includes a trigger proper and a retaining device. The retaining device is vertically movable from an upper position to a lower position and biased toward the upper position by a second spring. An upper end of the retaining device defines a detent for cooperating with the internal plunger. The detent is generally triangular in shape with a leading end facing in the direction of the guiding portion. The internal plunger includes a plurality of notches that cooperate with the detent in a ratcheting-type relationship to retain the internal plunger. The plurality of notches define various positions at which internal plunger may be retained. The retaining device defines a ramped surface that cooperates with a ramped surface of the trigger proper.

The means for imparting propulsion may include aspring 130 which is compressed upon forcibly introducing the projectile 114 into thechamber 130. The spring may be coupled in a manner known in the art to atrigger 132. In this regard, thetrigger 132 is coupled to the spring through a mechanism for retaining thespring 130 in its coil position (as shown inFIG. 5 ). When thetrigger 132 is pulled, the mechanism releases thecoiled spring 130 and allows thespring 132 impart the propulsion to the projectile 114.

The projectile 404 may be alternatively constructed of a material having a specific gravity greater than 1.0 and be provided with cavities trapping air or other naturally buoyant material such that the overall specific gravity of the projectile is approximately 1.0. The specific gravity of approximately 1.0 shall mean that the specific gravity of the projectile is such that the projectile may substantially maintain an intended path.
- The
submersible propelling structure 402 may generally include a grip portion or handle 414, a guidingportion 416 for guiding the projectile 404, and anarrangement 418 for imparting propulsion to the projectile 404.

Theinternal plunger 422 is shown removed from the remainder of the propellingstructure 402 inFIG. 12 . Theexternal plunger 420 may be movable between a first or unloaded position and a second or loaded position. The unloaded position is shown inFIG. 10 , for example. The loaded position is shown inFIG. 9 , for example. - The
internal plunger 422 may be coupled to theexternal plunger 420 for movement therewith. In this regard, it will be understand theinternal plunger 422 is similarly movable between a first or unloaded position (shown inFIG. 10 ) and a second or loaded position (shown inFIG. 9 ). Theinternal plunger 422 is biased toward the first position. As illustrated, theinternal plunger 422 may be biased toward the first position by aspring 430. Thespring 430 may be a coil spring the surrounds ashaft 432. In this embodiment, anenlarged head 434 of theinternal plunger 422 may be coupled to theexternal plunger 420. - The

Theinternal plunger 422 may include a plurality ofnotches 446 that cooperate with thedetent 444 in a ratcheting-type relationship to retain the internal plunger 422 (and external plunger 420) in loaded position. The plurality ofnotches 446 define various positions at which theplungers - The retaining
device 440 may define a rampedsurface 450 that cooperates with a rampedsurface 452 of the trigger proper 438. The trigger proper 438 is movable between a first position (shown inFIG. 11 ) and a second position (displaced to the left of that shown inFIG. 11 ). When the trigger proper 438 is squeezed and thereby advanced from the first position to the second position, the rampedsurfaces retaining device 440 and release the detain from engagement with thenotches 446 of theinternal plunger 422. - In use, the user loads the projectile 404 on the propelling
structure 402 by inserting the guidingportion 404 into thechannel 410 of the projectile 404. As the user draws the projectile 404 rearward relative to the propellingstructure 402, theexternal plunger 420, and correspondingly theinternal plunger 422, are displaced rearwardly toward their second position against the bias of thecoil spring 430.
