Patent Application
20120058704
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.
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 Stix™ 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”.
In a preferred embodiment, the floating, squirting toy comprises a housing having a chamber, the chamber having a variable volume defined by a first chamber end, a second chamber end and a interior surface, a hole through the housing adjacent the first chamber end allows communication between the chamber and the outside environment; a piston disposed adjacent the second chamber end, the piston being sealingly engaged with the chamber interior surface and adapted for longitudinal movement within the housing to vary the volume of the chamber; a shaft attached to the piston and having a portion extending out of the housing, the shaft portion extending out of the housing having a first handle attached thereto; an outer shell disposed over the housing, the shell creating a water impervious volume imparting a buoyancy sufficient to keep the toy afloat in water; and a second handle attached to one of either the shell or the housing. The toy is adapted to inhale water through the hole while the hole is submerged during the expansion of the chamber using the handles, and the toy being adapted to exhale the water through the hole during the contraction of the chamber using the handles. The outer shell may be chosen from one of a transparent, translucent material or a polymeric foam. The cross-sectional shape over a substantial portion of the outer shell may be chosen from at least one of round, polygonal, elliptical, oval, fanciful animal-like and some combination of shapes including generally polygonal with rounded sides.
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.
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 toy 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. The present invention also encompasses a shell of a shapes dissimilar to traditional “swimming noodles”. What is important is that there is sufficient material in the shell to provide buoyancy, i.e. the toy to floats when it is filled with water, and that the shell is soft, i.e. does not present a safety hazard when floating in the water.
A more complete understanding of the invention will be realized upon review of the following description and drawings of preferred embodiments of the invention.
A preferred embodiment of the invention is shown in
The toy 100 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 125 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
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.
In a most preferred embodiment, encapsulating shell 138 is formed from a material and of wall thickness to provide flexibility and ‘softness’ to the encapsulating shell. Examples of such materials include polyethylene terephthalate (PET or PETE), low density polyethylene (LDPE), high density polyethylene (HDPE). Materials and wall thickness parameters similar to those of standard carbonated beverage bottles will provide sufficient ‘softness’ to form a safe squirting toy, i.e. the toy 100 having encapsulating shell 138 of the most preferred embodiment will not injure a person hit with the toy at typical velocities. Encapsulating shell 138 may be supported at one or more points along its length by a shell support 150. Alternatively, a much thinner wall thickness may be chosen and the toroidal space slightly pressurized. Proper choice of pressure will result in encapsulating shell 138 maintaining a selected 3-dimensional shape while remaining soft enough to offer safety benefits.
In another preferred embodiment of the squirting toy, encapsulating shell 138 may be transparent, semi-transparent or translucent. Such a preferred embodiment is shown in
Handle portion 132 may include 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. The shells may also be blow molded or rotationally molded air-filled cylindrical bladders or similar materials, as illustrated by encapsulating shell 32 in
A most preferred embodiment of the present invention has the squirting toy emulating a “swimming noodle”, well known in the context of recreational water activities. When the handle portion is retracted, as in
In a more preferred embodiment, one of either the housing 106 or the shell 138 has a handle 132B extending therefrom. Handle 132B may also have a palm surface 135 and a finger surface 136. Grasping both handle 132A and 132B and forcing them away from one another while hole 114 is below the water surface 104 causes water to be inhaled into the expanding forward chamber portion 110A through hole 114. Subsequent forcing of handles 132A and 132B toward one another causes water in chamber portion 110A to be exhaled through hole 114 in a powerful stream 102.
In another preferred embodiment of the present invention, the handle portion of squirting toy 100 may take a fanciful form. An example is shown schematically in
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.
