AIR PROPELLED AQUATIC TOY Filed Feb. 21, 1964 United States Patent 3,246,419 AIR PROPELLED AQUATIC TOY Gustav J. Pawelka, Sunset Ave., Glenwood Landing, N.Y., and Frederick H. Kroll, 72 Wood Hollow Lane, New Rochelle, N.Y.

Filed Feb. 21, 1964, Ser. No. 346,582 10 Claims. (Cl. 46-8) The present invention relates generally to improvements in toys and the like. It relates in particular to an improved self-propelled aquatic toy which produces and emits bubbles attendant the motivation thereof.

Inflatable rubber balloons have long been employed as sources of compressed air for the air-jet propulsion of toy vehicles, both along a solid surface and in water. However and particularly when used as the motive power for driving aquatic toys, the arrangements heretofore proposed and available possessed numerous disadvantages. For one thing, the compressed air was employed merely to propel the toy and served no other purpose or function. Also, they were generally expensive devices or were devices awkward and diflicult to operate. They otherwise left much to be desired.

It is, therefore, a principal object of the present invention to provide an improved air-jet propelled toy.

Still another object of the present invention is to provide an improved air-jet propelled aquatic toy motivated by an inflated elastomeric balloon.

A further object of the present invention is to provide an improved aquatic toy self-propelled by compressed air wherein the compressed air serves additional functlons.

Still a further object of the present invention is to produce an improved bubble-producing aquatic toy.

Another object of the present invention is to provide a toy of the above nature characterized by its simplicity of construction, ruggedness, ease of operation, low cost, attractive appearance and unique performance.

The above and further objects of the present invention will become apparent from a reading of the following description, taken in conjunction with the accompanying drawing, wherein FIGURE 1 is a longitudinal sectional view, taken along line 11 in FIGURE 2, of an aquatic toy embodying the present invention;

FIGURE 2 is a top plan view thereof;

FIGURE 3 is an enlarged sectional view taken along lines 3-3 in FIGURE 1;

FIGURE 4 is an enlarged sectional view taken along lines 4-4 in FIGURE 1; and

FIGURE 5 is an enlarged sectional view taken along lines 5-5 in FIGURE 1.

In a sense, the present invention contemplates the provision, in a toy comprising a body member, of a pair of longitudinally spaced front and rear openings formed therein adjacent to the bottom thereof, means defining a channel extending between said front and rear openings, a compressed air reservoir communicating with said front opening and a reservoir adapted to contain a liquid communicating with said rear opening.

According to a preferred form of the improved aquatic toy, the body member includes a main section and an auxiliary section. The main section is a buoyant, hollow, water-tight member formed of collapsible, material normally urged to its expanded condition, and has, a well extending therethrough. adjacent its rear portion. The auxiliary section nests snugly in the main section well and has'a pair of longitudinally-spaced openings formed in the bottom thereof, the channel connecting the openings being upwardly, rearwardly inclinedand terminating in a rearwardly directed opening. An upwardly extending tube communicates with the front opening and engages the throat of an inflatable elastomeric balloon constituting an air storage tank. The reservoir communicating with the rear opening is in the shape of a cup formed in the auxiliary body member section. A pair of communicating ports are formed in the main body member section and the balloon carrying the tube and a check valve is associated therewith which permits the flow of air through these ports only into the tube. A second port is formed in the upper part of the main body member section and has a check valve associated therewith which permits the flow of air therethrough only into the main body member section.

Referring now to the drawing which illustrates a preferred embodiment of the present invention, reference numeral 10 generally designates the improved aquatic toy which includes a main body member 11 and an auxiliary body member 12. The main body member 11 may be in the shape of a ship, as illustrated, or may assume any other desirable shape, and is hollow, watertight and buoyant. Furthermore, the main body member 11 is defined by easily compressible walls of a resilient material which are normally urged to their expanded condition and may be formed of rubber or a synthetic elastomeric material, a synthetic thermoplastic resin such as polyethylene, polypropylene, polyvinyl chloride, saran, or the like.

Body member 11 is preferably integrally formed in any suitable manner and includes an enlarged peripheral section 13 which extends around the body member 11 and communicates with a rear transverse tubular section 14. Extending through body member 11, just forward of tubular section 14, is a rear, medially-disposed vertical well of rectangular transverse cross-section delineated by a rear wall 16 which also defines the front wall 16 of tubular section 14, a front wall 17 and side walls 18. Forming part of body member 11 is a raised superstructure 18a and a bottom section 15 of any desirable shape, the raised superstructure including an upwardly directed centrally located valving section 19.

The auxiliary body member 12 is preferably formed of a relatively rigid material, such as a synthetic organic design, for example, a high density polyethylene or polypropylene, polystyrene, or the like, and telescopes or nests snugly in the well formed in the main body member 11 and has a transverse cross-section approximateiy that of said well. Body member 12 is open topped and includes a rear wall 20 abutting wall 16 and it has a front wall 21 abutting wall 17. A port-defining tapered tubular nozzle 22 is formed on front wall 21 of member 12 and projects through a registering port formed in wall 17 to define communication between the interiors of main and auxiliary body members 11 and 12. Cooperating with the front wall 21 to form therewith an upwardly directed tube 23 is an intermediate wall, tube 23 projecting above the level of wall 17 and terminating in an outwardly directed peripheral bead 26.

Extending along the bottom of auxiliary body member 12 is an upwardly, rearwardly-inclined, bottom wall 27 having downwardly directed side flanges 28 which delineate therewith an upwardly rearwardly inclined channel 29 of arcua-te transverse cross-section. Wall 27, flanges 28 and channel 29 extend rearwardly beyond wall 16 to terminate in a rearwardly-directed opening. The front end of the channel 29 is closed by the lower section 30 of wall 21 which depends below the bottom of the main body member 11. The rear upper face of channel wall 27 abuts the underface of the main body tubular section 14.

The side walls of the auxiliary body member and the rear and intermediate walls 20 and 24 delineate, with bottom wall 27, a cup shaped liquid reservoir 33 for holding a soap solution or other bubble forming liquid L. Formed medially on the trailing end of reservoir 33 is a small opening 34 which affords liquid communication between the trailing sect-ion of the channel 29 and reservoir 33. A second small opening 36 is formed in the front section of channel 29 concentrically with tube 23 and affords com munication between the tube 23 and the leading section of channel 29.

An inflatable balloon 45 defines a compressed air reservoir and is of any desired shape and is formed of rubber or other suitable elastomeric material. Balloon 45 includes the conventional throat section 35 which snugly engages the beaded edge of tube 35 [to releasably couple balloon 45 to tube 23 and effect communication between their interiors.

The main body member 11 functions as a hand pump to inflate the balloon 45. A pair of check valves are provided in onder to restrict the flow of air from the exterior into body member 11 and from body member 11 into tube 23. The first check valve includes an elongated rectangular flap member 37 preferably formed of rubber or the like. Flap 37 cooperates with the fiat front inner face 38 of tube 23 and is secured along its upper edge to face '38 at a point above the inner opening of the nozzle 22. In normal position, with air pressure in tube 2-3 greater than that in the main body member 11, flap 37 closes the nozzle opening thereby preventing backflow of air therethrough from tube 23. However, upon squeezing the Walls of main body 11 to increase the pressure therein beyond that in tube 23, the increased pressure effects the opening of the valve flap 37 and the flow of air through nozzle 22 into tube 23.

The second check valve is located in valve section 19, which includes an upwardly directed peripheral Wall 39 provided with an inwardly directed flange 40 from the inner edge of which depends an integrally formed cup shaped member 41. Nested in cup 41 is a relatively rigid bushing 42 having 'a bottom peripheral bead 43 which stretches the corresponding section of cup 41 to effect a tight coupling of the bushing. An arcuate slit 44 of less than 360 is formed in the bottom wall of cup 41 radially outside the periphery of the bore in bushing 42. Slit 44 delineates a flap 46 hinged along a line extending between the ends of slit 44-, which flap cooperates with the underface of bushing 42 to define the second check valve. Flap 46 normally closes the bushing bore, particularly when the pressure within body 11 is greater than the exterior to prevent backflow of air through the bushing 42 attendant to the squeezing of the body member 11. However, during the expansion of body 11 following the squeezing thereof, the reduced pressure within said body 11 effects the opening of flap 46 and the flow of air from the exterior into the interior of body 11.

Considering now the operation of the improved aquatic toy 16} described above, a bubble forming liquid L is poured into reservoir 33 and the balloon 45 inflated the desired amount by repeatedly compressing and releasing body 11 which effects the flow of air from the interior of body 11 into the balloon 45 by way of tube 23 and from the exterior into the interior of body 11 through bushing 42, in the manner earlier described. During theinflation of the balloon 45, opening 36 may, if desired, be closed by pressing a finger against it. The aquatic toy is then floated in a pool of water with the channel 29 immersed therein. Successive bubbles B of compressed air will issue from opening 36 and will flow rearwardly along the upwardly and rearwardly inclined top of channel 29 past the reservoir opening 34. As the bubbles and water flow past the. opening 34, they draw along therewith some of the bubble-forming liquid in the reservoir. The bubbles'of compressed air increase insize in their rearward flow and with the decrease in surface tension effected by the mixture of the liquid L withthe passing water, they expand to large bubbles as they leave the trailing end of the channel 29 and emerge to the surface of the water. The bubbles B traveling rearwardly along the channel 29 and emitted from the rear opening thereof effeet the forward propulsion of the aquatic toy.

Many materials have been found suitable for the liquid L, such as liquid deter-gents, liquid bubble mixtures marketed for use with bubble blowing toys, aqueous solutions of powdered detergents and, preferably, the commercially available liquid shampoos. The air and

liquid openings

36 and 34 are advantageously small, the air opening 36 advantageously having a diameter of about .032 inch and the opening 34 being smaller and advantageously having a diameter of about .023 inch.
