## Title
Squirting toy

## Abstract

A squirting toy is comprised of a cylindrical housing and a piston that slides within to force water into or out of the housing via a hole therein. The housing is encased within a polyethylene closed cell foam shell. The shell is non-absorbing, so that the foam remains buoyant and keeps the gun afloat indefinitely when left in water. The foam is soft, so that the gun is not a safety hazard when left floating in a swimming pool.

## Background
FIELD OF THE INVENTION
The present invention is a water squirting apparatus for use at play. More specifically, it is a soft floating tubular piston type squirt gun for use such as in a swimming pool or swimming area by participants in or adjacent to the water.
BACKGROUND AND OBJECTS OF THE INVENTION
Squirt guns are well known in many forms in the prior art. Numerous squirt guns and squirting toys are made and have been made over the years for use by persons while swimming in or standing adjacent to a swimming pool, which are adapted to quickly take in water from the swimming pool for squirting. One such toy is called Water StixTM and is sold by Hearthsong Inc. This toy, representative of many such squirting toys, is basically comprised of a housing having a nozzle at its squirting end. A piston, which includes a graspable handle, is adapted to slide within the housing so that, when the nozzle end of the housing is submerged in the pool and the piston is pulled backwards, water is drawn into the housing through the nozzle. And when the piston is subsequently forced forwardly, that water is forced from the housing, through the nozzle, towards a target, in a powerful stream.
Additionally, many squirt guns of the prior art are constructed in a manner that entraps air and thereby inadvertently enables those guns to partially float in water. The degree of such buoyancy is relative to the amount of water that has been taken into the gun and the longevity of such buoyancy is relative to the to the amount of air leakage from the housing.
There are also floating toy “swimming noodles” in the prior art, which are made of resilient floating closed-cell polymer foam. These toys are used to provide buoyancy to the user while swimming. Because these toys are often left floating in the pool when not in use, their softness eliminates the safety threat that they would otherwise pose.
It is therefore an object of the present invention to provide an improved squirting toy that floats fully atop the surface of the water, whether filled with or empty of water.
It is a further object to provide a soft squirting toy that is safer that squirting toys of the prior art.
It is a further object to provide a squirting toy that is both buoyant and soft.
It is a further object to provide such a squirting toy that has a similar appearance to a “swimming noodle”.
Further objects and advantages of the invention will be apparent upon a review of the following description and drawings of the invention, including the preferred embodiment thereof.
SUMMARY OF THE INVENTION
The present invention comprises a squirting toy that is housed within a polyethylene (PE) closed cell foam shell. The closed cell shell is non-absorbing, so that the foam remains buoyant and keeps the gun afloat indefinitely. The foam is soft, so that the gun is not a safety hazard when left floating in a swimming pool. In the preferred embodiment, the squirting toy is comprised of a cylindrical housing and a piston that slides within to force water into or out of the housing via a hole therein. The foam shell of the preferred embodiment is similar in size and shape to a “swimming noodle”, and is therefore more attractive to a child who is familiar with such.
A more complete understanding of the invention will be realized upon review of the following description and drawings of the Preferred embodiment of the invention.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an action view of a squirting toy according to the preferred embodiment of the invention showing water being expelled there-from.
FIG. 2 is a cross-sectional view through the toy of FIG. 1 in its retracted/empty state.
FIG. 3 is an enlarged partial section of the toy of FIG. 1 floating in water,
FIG. 4 is an action cross-sectional view in showing the intake of water into the toy of FIG. 1, and
FIG. 5 is an action cross-sectional view in showing the expulsion of water from the toy of FIG. 1.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The Preferred embodiment of the invention is shown in FIGS. 1 though 5, where there is depicted a toy 100 for squirting a water stream 102, and which is adapted to float on the water surface 104.
The toy comprises a rigid tubular housing 106 that encloses a hollow cylindrical chamber 110. The forward end 112 of the tubular housing is closed except for a small hole 114. Piston 116 slides longitudinally within chamber 110 and is sealed against the cylindrical inner surface 120 of the chamber by o-ring 122, which is seated within groove 124 of the piston. The piston separates the chamber 110 into a forward portion 110A and a rear portion 110B. The piston 116 is rigidly connected to shaft 124 at the forward end 126 thereof. Slide bushing 128 supports shaft 124 at the rear end 130 of the tubular housing 106, while allowing longitudinal movement relative thereto. Handle portion 132 is rigidly connected to shaft 124 at the rearward end 134 thereof. Expansion of the handle portion 132 relative to the tubular housing 106, while hole 114 is below the water surface 104, as depicted in FIG. 4, causes water to be inhaled into the expanding forward chamber portion 110A, through hole 114. Subsequent retraction of the handle portion 132 relative to the tubular housing 106 causes that water to be exhaled through hole 114 in a powerful stream 102.
Tubular shell 138, preferably made of closed-cell polyethylene foam, surrounds tubular housing 106, to provide both a soft protective surface and buoyancy. Other materials may be substituted for polyethylene foam, such as ethylene vinyl acetate closed-cell foam.
Handle portion 132 also includes handle shell 140, which is preferable made of the same foam, and is rigidly connected shaft 124 by means of support bushings 144 and 146. Alternatively, other materials having sufficient buoyancy, softness, and water impermeability, such as polyurethane foam, may be used for both the tubular and handle shells. Or the shells could instead be replaced by blow molded or rotationally molded air-filled cylindrical bladders. When the handle portion is retracts as in FIG. 2, the shells create a similar appearance and feel to those of a common “swimming noodle”.
It will be appreciated by those skilled in the applicable arts that the foregoing is merely one of many possible embodiments of the invention, and that the invention should therefore only be limited according to the following claims.
