HANDHELD BUBBLE FORMING MECHANISM

Abstract

The top of a ring-like film forming member with an opening receives bubble solution and gravity causes the solution to flow over the protruding surface of a movable member within the opening such that the surface tension of the bubble solution causes a film to form within the opening and over the surface. The movable member is moved out of the way to allow wind from a wind supply to reach the rear of the ring-like member to form and release a bubble. The protruding shape of the surface allows the film to form and in intact as the member is moved. A trigger mechanically connected to the movable member controls the position of the movable member and the energization of the motor which drives the bubble solution supply and the wind supply. Continuous depression of the trigger causes a series of bubbles to be formed and released.

DETAILED DESCRIPTION OF THE INVENTION

[0053] FIG. 1A, FIG. 1B and FIG. 1C show the exterior housing or shell 10 of the handheld bubble forming mechanism respectively from the front, side and rotated such that part of the front and part of the side are visible. Shell 10 may be made of plastic and includes a substantially spherical top portion 12, a handle portion 14 and a bubble solution container 16.

[0054] As seen in FIGS. 2 and 3, spherical top portion 12 of shell 10 houses a compartment which holds one or more batteries accessed through a removable shell section 22 at the top portion of the shell. Top portion 12 also contains the parts which form the bubbles, including a film forming member 18 and a device which supplies wind to member 18. Below member 18 is a beak-shaped drain 20 which catches bubble solution overflow from member 18 and via an internal tube (not shown) returns same to the bubble solution container 16.

[0055] The handle portion 14 of the shell includes a spring-loaded trigger 24 which can be depressed from its extended position to control bubble production. When released, trigger 24 automatically returns to its extended position.

[0056] The bubble solution container 16 may take the form of a plastic bottle with an externally threaded neck. The bottle neck is received within a recess in the bottom of the handle and is connected to supply bubble solution to the film forming member 18 when the trigger is depressed.

[0057] Trigger 24 is mechanically connected to the parts which form the bubbles located in top portion 12 by a control rod 26. The trigger is also connected to activate the wind supply and the bubble solution supply when the trigger is depressed.

[0058] Rod 26 has a bottom section 26A, a main section 26B and a top section 26C which are connected to the internal surface of the shell in a manner which transfers the depression of the trigger to control the movement of the bubble forming parts, the activation of the bubble solution supply and the activation of the wind supply.

[0059] Trigger 24 rotates about a shaft 28 protruding from a recess in the shell wall when depressed. Section 26A is also connected to and rotates with the trigger such that depressing the trigger causes section 26A to rotate around shaft 28 in a counterclockwise direction in turn causing rod 26 to move toward the top of the device.

[0060] Section 26B of the control rod has a part 30 which extends from the side of the rod. Part 30 is situated to engage the contacts of a switch 32 when rod 26 is moved toward the top of the shell cause the contacts of switch 32 to close. Closing the switch contacts causes switch 32 to connect one or more batteries 34, located in a compartment 35 within top portion 12 of shell 10, with a motor 36.

[0061] Motor 36 is connected to drive both the bubble solution supply 38 and the wind supply 40 when activated by depressing trigger 24. The bubble solution supply includes a flexible bubble solution supply tube 42 and a series of gears, generally designated 43, abutting the supply tube 42. One end of supply tube 42 is situated within the bubble solution container 16.

[0062] Rod 26 has a part 45 which moves with the rod and is attached to drive the gears 43 to alternately apply pressure to compress the adjacent section of the supply tube 42 and release the pressure when the gears are rotated by motor 36 to siphon bubble solution from container 16 to the film forming parts in the top portion 12 of the shell.

[0063] Motor 36 is also connected to drive the wind supply 40. The wind supply 40 is located in the top portion of the shell below the battery 34 and includes an impeller 44 within a casing 46. When activated, motor 36 causes impeller 44 to rapidly rotate within casing 46 to provide wind to the film forming parts through a wind supply conduit 58, as described in greater detail below.

[0064] The bubble forming parts in the top portion of the shell include film forming member 18, which is attached to the front of the shell and a member 50 which is moved relative to member 18 by control rod 26. Member 50 is movable relative to member 18 between the initial position, in which member 50 is proximate to member 18, and a remote position, in which member 50 is remote from member 18.

[0065] Member 18 has a ring-like configuration defining an opening 52. The top portion 54 of member 18 is situated over opening 52. Member 50 has a protruding surface 56 approximately the same size and shape of opening 52 in member 18. The protruding shape of surface 56 allows member 50 to easily “detach” from the bubble solution film being formed within opening 52 while not breaking the bubble solution film. Surface 54 is preferably conical, hemispherical, arcuate, pointed or any combination thereof.

[0066] In the initial position in which members 18 and 50 are proximate each other, surface 56 is situated within opening 52 in member 18. In the remote position of the members, surface 56 is spaced from member 18.

[0067] Bubble solution supply tube 42 is connected to supply bubble solution to the top portion 54 of member 18 when motor 36 is activated, as explained above. Wind supply 40 provides wind to back of member 18 through a wind supply conduit 58 when the motor is activated.

[0068] When trigger 24 is depressed, motor 36 causes bubble solution to be supplied to the top portion of member 18 and wind is supplied to member 18. When the trigger is released, the motor is turned off.

[0069] FIG. 4 shows the internal components before trigger 24 is depressed the first time, with member 50 in the initial position proximate member 18. When the trigger is depressed a first time the motor is activated to cause the bubble solution supply to supply bubble solution to the top of member 18, to cause the wind supply to supply wind to member 18, and to move member 50 to the remote position, away from member 18.

[0070] When the trigger is released, the motor is turned off. Member 50 is automatically returned to the proximate position as control rod 26 is moved back to its original position by a spring 51 extending between the control rod and the shell.

[0071] FIG. 6 shows the internal components before trigger 24 is depressed the second time. As the trigger is depressed the second time, the motor activates the wind supply to provide wind to member 18 and activates bubble solution supply to supply bubble solution to the top portion 54 of member 18. Gravity then causes the bubble solution from the top of member 18 to flow into opening 52 such that the surface tension of the bubble solution forms a film within the opening and over surface 56 of member 50. Member 50 is the withdrawn from opening 52 by movement of control rod 26 as depicted by arrow 47 in FIG. 7 and moved to the remote position. In that position of member 50, wind from the wind supply can reach member 18 and cause the film in opening 52 to form and release a bubble 66, as indicated by arrow 49 in FIG. 7.

[0072] FIGS. 5A-5D, 8A-8D and 9A-9D respectively illustrate three preferred embodiments of the mechanism which moves member 50 to its remote location relative to member 18. In FIGS. 5A-5D and in FIGS. 8A-8D, member 50 is rotated about the axis of a shaft 60 by the movement of rod 26. In FIGS. 9A-9D, member 50 is moved away from member 18 in a direction generally perpendicular to the plane of member 18 by rod 26. In all embodiments, member 50 is moved to a position which allows wind from wind conduit 58 to reach the rear of member 18 such that the film previously formed within opening 52 creates the bubble.

[0073] More specifically, FIGS. 5A, 8A and 9A each show an elevation view of the front of member 18, a cross-sectional view of member 18 and a cross-sectional view of member 50 in its initial or proximate position. In that position, surface 56 is within opening 52 of member 18. Also shown is bubble solution supply tube 42 in cross-section and the wind supply conduit 58 in cross-section.

[0074] In FIGS. 5A and 8A, member 50 is rotated around shaft 60 (FIG. 8A labeled 62 for the shaft) which extends from the interior of the shell near the top of the device. Shaft 60 is attached to rod section 26C such that member 50 is moved to the remote position as control rod 26 is moved upward by depression of trigger 24. In FIG. 9A, member 50 moved laterally away from member 18, as described below. Those figures also show the bubble solution supply tube 42, prior to bubble solution being provided to member 18, and the wind supply conduit 58.

[0075] FIGS. 5B, 8B and 9B show bubble solution being supplied to the top 54 of member 18 through bubble solution supply tube 42.

[0076] FIGS. 5C, 8C and 9C show member 50 as it is being moved to the remote position. In FIG. 5C, member 50 is rotated around shaft 60 at the top of the member as noted. In FIG. 8C, member 50 is rotated around a shaft 62, which is located at the bottom of the member. Shaft 62 serves the same purpose as shaft 62 and is also attached to rod section 26C, which in this case would be elongated to accommodate the different location of the shaft. In FIG. 9C, when the trigger is depressed, the control rod is directly connected to the control rod such that member 50 is moved away from member 18 in a direction generally perpendicular to the plane of member 18, toward a circumferentially expanded section 64 of wind supply conduit 58.

[0077] FIGS. 5D, 8D and 9D show member 50 in its final remote position. In FIG. 5D, member 50 is situated at the top of wind supply conduit 58 such that wind from the wind supply can move under member 50 to member 18 to create bubble 66. In FIG. 8D, member 50 is situated at the bottom of wind supply conduit 58 such that wind from the wind supply can move over member 50 to member 18 to create bubble 66. In FIG. 9D, member 50 is moved away from member 18 in a direction generally perpendicular to the plane of member 18 to section 64 which has a diameter larger than that of member 50 such that wind from the wind supply can move around member 50 to opening 52 in member 18 to create the bubble.

[0078] FIGS. 11A and 11B are respectively front and rear perspective views of member 18, showing the member in greater detail. Member 18 includes a circular channel 68 which at least partially surrounds opening 52. The channel is formed an outer wall 70, an inner wall 72 spaced from outer wall 70 and a wall 74 connecting the inner and outer walls. Inner wall 72 defines opening 52.

[0079] A portion of wall 72 consists of a plurality of spaced protrusions or “spikes” 80. Bubble solution is supplied to member 18 through port 82 which is connected to the bubble solution supply tube 42. Port 82 is connected to channel 68 such that bubble solution from port 82 flows into the channel near the top 54 of member 18. Once the bubble solution enters the channel, gravity causes the bubble solution to fill the channel and flow between protrusions 80 into opening 52 in member 18.

[0080] When member 50 is in position proximate member 18, surface 56 is within opening 52. The surface tension of the flowing bubble solution forms a film within the opening and over surface 56. Withdrawing member 50 to a position remote from member 18 allows wind from the wind supply conduit 58 reach member 18 from behind and create the bubble 66 from the film.

[0081] Depression of the trigger activates the bubble solution supply and the wind supply causing a series of bubbles to be formed. Each time the trigger is depressed after the first time, the film is formed and member 50 is moved to the remote position allowing wind to form a bubble. Continuous depression of the trigger will cause a series of bubbles to be formed and released. Since the motor and the gear system will continuously siphon the bubble solution from the bubble container to the top portion of member 18 and provide a constant supply of bubble solution, bubbles are continuously be formed until the trigger is released.

[0082] As illustrated in FIGS. 10A-10E, it is possible to modify the bubble forming mechanism to form and release more than one bubble at a time. Each FIG. 10A-10E includes elevation view of the front a multiple opening film forming member 90 and a cross-sectional view of the movable member which in this case takes the form of a rotating platform 92 having multiple members 94 with protruding surfaces, similar to those of member 50.

[0083] FIG. 10A shows the members in the initial position before the bubble solution is supplied to member 90. FIG. 10B shows the members as bubble solution from bubble solution supply tube 42 is supplied to the top of member 90 and film is formed within the opening in member 90 and over the members 94 situated in the openings. FIG. 10C shows platform 92 with members 94 being moved to the position remote from member 90. FIG. 10D shows platform 92 rotated about a central axis 96. FIG. 10E shows that wind from wind supply conduit 58 causes more than one bubble to be formed and released.

[0084] In one preferred embodiment, once the bubble solution film is formed on the multi-opening member, the platform is rotated approximately 30 degrees thus allowing the wind created by the wind supply behind member 90 to blow air thru the openings. Subsequently, the platform will be rotated back for the same 30 degree and members 94 to be inserted within the openings in member 90 again and another series of bubble solution films will be formed. With this continued in a back and forth manner, large amounts of bubbles can be formed.

[0085] As noted in the above, most of the conventional bubble making devices involve a moving bar to “wipe” or a moving plane or a moving plane containing bubble rings to move against an object in order to form a bubble film. One of the major drawbacks of these designs is that the bar or the plane must be in very close proximity to the bubble rings in order to form the bubble film. If there exists a small gap, which in actual production may happen due to tolerance or assembly issues, no bubble films can be formed across the bubble rings. This issue often leads to bubble making devices being deemed to be defective as no bubbles can be produced.

[0086] With the novel film forming member and movable member with the protruding surface of the present invention, neither a moving bar nor a moving object is needed to move against the bubble rings to form a bubble film. Instead, the protruding surface of the movable member is being “stamped” into the bubble solution film within the opening and thus the bubble solution film can be formed with a much higher success rate as opposed to the existing bubble film making devices.

[0087] The protruding surface of the movable member also allows the member to be detached more easily from the film, reducing the chance of breaking the film being formed. As described above, there are several ways of moving the movable member while keeping the film intact.

[0088] While only a limited number of preferred embodiments of the present invention have been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims.
