The present invention relates generally to toys, and more specifically to a battery powered toy device that produces bubbles from a liquid solution.
There have been many bubble toys over the years that operate in various ways. However, most bubble toys are hand-held rings that are either blown through or hand waved by the user to produce a small amount of bubbles. It is desired to provide a toy that produces a steady stream of bubbles and a safe entertainment for a child. The present invention is an improved battery powered toy device that produces bubbles from a liquid solution. In the present invention, the battery compartment can be a sealed container with external contacts, which prevents fluid from penetrating the interior of such container and the battery. The present invention also has an improved access to the battery compartment interior. Additionally, the present invention improves the quality of play pattern with the addition of lights and/or sounds in a cost-effective manner.
The present invention is a bubble toy device that produces bubbles by pulling a trigger, which causes power to be applied to an electrical circuit and/or system that activates a pump, or pump mechanism, and a fan, or fan mechanism. In one (1) embodiment, the pump can be electromechanical and driven by an electric motor. In other embodiments, the pump can be purely mechanical and activated by a trigger mechanism in a similar manner as mechanical water pistols are trigger activated.
One (1) embodiment of the present invention has a separate sealed internal battery compartment with external (i.e., exteriorly connected) electrical contacts within the bubble toy device. If the pump is electromechanical and driven by an electric motor, such separate sealed internal battery compartment with external electrical contacts provides the source of power that drives an electrical motor, which operates the pump and the fan that produces a moving stream of air, or air stream that flows through an air channel within the fan shroud. Such moving stream of air originates as stationary or near-stationary ambient air outside the housing of the invention, which enters the housing through holes, and is subsequently accelerated by the fan to produce the moving stream of air. The air channel within the fan shroud directs the air stream towards a secondary opening of the bubble toy device housing through a generally circular-shaped dispensing aperture defined within a movable dispensing ring, which directs the air stream back to the ambient.
The sealed battery compartment of the present invention can have a cover that is attached, and separated or opened by the use of an attaching and removing device, fastener or screw, which is to be tightened to close, and loosened or removed to open. The sealed battery compartment is designed to allow insertion and removal of batteries from the side of a handle on said compartment. The sealed battery compartment can also be located above the fan shroud on the top of the bubble toy device. If the sealed battery compartment is located above the fan shroud on the top of the bubble toy device, the batteries can be inserted and removed from the top and/or side of said compartment.
In one (1) embodiment of the present invention the moveable dispensing ring defines a dispensing surface upon which liquid bubble solution adheres to the moveable dispensing ring across a dispensing aperture. The liquid bubble solution utilized in the present embodiment may be obtained or sold separately, or in conjunction with the bubble toy device in the same packaging or box. The bubble toy device may have threads defined in the walls of a primary opening to which a typical, commercially sold bubble solution container may be removeably-attached by mating said threads in the walls of the primary opening with complimentary threads defined on the outside walls of said typical, commercially sold bubble solution container. The bubble toy device pump, whether electromechanical or mechanical, causes movement of the bubble solution through at least one (1) tube, which causes the bubble solution to be delivered to the moveable dispensing ring, or stationary dispensing ring in another embodiment. Pulling the trigger of the present invention activates the electromechanical pump, the fan, and initiates an up-and-down motion of a film producing mechanism. The film producing mechanism moves the dispensing ring in an up-and-down motion across a stationary application bar, which can be horizontally or diagonally oriented, thus sweeping a layer of bubble solution over the dispensing aperture of the moveable dispensing ring, or the stationary dispensing ring in another embodiment. At the same time that the bubble solution is swept over the dispensing ring, the air stream generated by the fan travels through the air channel within the fan shroud and expels one (1) or more bubbles from the secondary opening of the bubble toy device.
If excess bubble solution accumulates on the moveable dispensing ring, a drip flange located at the base of the moveable dispensing ring directs the excess bubble solution downward into a drip channel attached to a threaded base. The drip channel can direct the excess bubble solution into the ambient or a bubble container when a bubble container is so attached. It is preferable for the drip channel to be funnel-shaped, being wider at the top facing the dispensing aperture and narrower at the bottom.
In embodiments of the present invention employing a mechanical pump, all the basic components of the embodiments using an electromechanical pump are present. Therefore, only the added features need be explained and are discussed below.
When employing a mechanical pump, there can be an electromechanical sequence whereby two (2) displacement regimes are sequentially activated by the displacement of the trigger, and the entire displacement range of the trigger is divided into two (2) displacement regimes, with a first displacement regime occurring when the trigger is first displaced by squeezing the trigger, and a second displacement regime occurring after the first displacement regime, which continues as the trigger is increasingly displaced by continued squeezing until the trigger is maximally displaced. When the trigger is first squeezed, there can be a closure of an electrical switch caused by a small initial displacement of the trigger, and the switch can remain closed during the entire displacement range of motion of the trigger. The film producing mechanism can be activated during the first displacement regime and the mechanical pump can be activated during the second displacement regime. The ability to activate the film producing mechanism during the first displacement regime and the mechanical pump during the second displacement regime enables a very useful feature whereby the film producing mechanism can be operated during the first displacement regime independently of the mechanical pump and the mechanical pump can be operated during said second displacement regime independently of the film producing mechanism. Such independent operation can be utilized by squeezing the trigger all the way, partially releasing the trigger, re-squeezing the trigger several times in order to pump bubble solution to the dispensing ring, releasing the trigger all the way, and partially operating the trigger so as to only actuate the film producing mechanism. During the aforementioned independent operation sequence, the fan can produce an air stream to continue to blow bubbles so long as there is sufficient bubble solution on the dispensing ring. When the bubble solution supply is exhausted, the trigger can be depressed all the way to pump more bubble solution on the dispensing ring.
In embodiments employing a mechanical pump, such as the embodiment(s) just described above, one (1) embodiment can employ a movable dispensing ring on a film producing mechanism that is pivotally attached to the fan shroud, and a stationary application bar can be attached to a drip channel. Another embodiment can employ a moving application bar on a film producing mechanism that is pivotally attached to the fan shroud, and a stationary dispensing ring can be positioned such that the center of the air stream is directed through the dispensing aperture.
In one (1) embodiment, the bubble toy device of the present invention may also have one (1) or more light-emitting diode (LED) lights or lighting system(s) that are activated by manually pulling the trigger, or by a switch. The bubble toy device of the present invention may also have a sound-producing device that is also activated by pulling the trigger, or by a switch. Such LED lights and sound-producing features taken together or individually increase the overall enjoyment of the bubble toy device and make the bubble toy device more appealing to children.
Further appeal can be realized when light can be transmitted into the removeably-attachable container that can contain bubble solution, which can occur when a flexible or rigid light pipe that can be made from any material that can transmit light is utilized.
The bubble toy device housing can, in whole or in part, have an animal, character, or creature style and/or is a molded shell of an animal, character, or creature.

Many types of electrically driven pumps may be used for the electromechanical pump 120, such as a gear pump, a screw pump or a plunger pump or other positive displacement pump. In the electromechanical pump 120 shown in
Bubble solution exits the electromechanical pump 120 through the electromechanical pump output 158 and is transported through a feed tube 125 and exits the feed tube 125 near the moveable dispensing ring 114. The fan 122 produces moving air that is expelled through an air channel 126 defined in the fan shroud 123 and subsequently exits through the dispensing aperture 116. Inlet air is provided to the fan 122 through a hole and/or series of holes in fan shroud 129 at the top of the fan shroud 123. A film producing mechanism 124 is pivotally attached to the air channel 126.
The film producing mechanism 124 moves the moveable dispensing ring 114 in an up-and-down motion next to the stationary application bar 154 to deposit a thin film of bubble solution on the moveable dispensing ring 114. The film producing mechanism 124 is mechanically linked to the trigger 110 such that pulling the trigger 110 raises the film producing mechanism 124 and releasing the trigger 110 lowers the film producing mechanism 124. In other embodiments, pulling the trigger 110 lowers the film producing mechanism 124 and releasing the trigger 110 raises the film producing mechanism 124.
When air moves through the air channel 126 and past the moveable dispensing ring 114, the flowing air creates a bubble or many bubbles that float away from the bubble toy device 100. If there is any excess bubble solution on the moveable dispensing ring 114, this solution drips down a drip flange 128, into a drip channel 130 attached to or defined within an interior of the bubble toy device housing 102, and eventually returns to primary opening 104 which can lead to the ambient, any type of reservoir, source of liquid, or a removeably-attachable bubble solution container (not shown).
The film producing mechanism 124 is pivotally connected to the air channel 126. A first end 150 of the film producing mechanism 124 has a U-shaped portion which is attached to the air channel 126 using fastener 151 (shown in
A center portion of torsion spring 160 is attached to rod 162 with a first spring end 164 attached to the flat plate 142 or its extension 144. A second spring end 166 is secured rigidly in place at or leans against a shoulder 168 defined in the bubble toy device housing 102. With this arrangement, the pulling of the trigger 110 by a user causes the flat plate 142 to slide against and displace the torsion spring 160, thus causing the torsion spring 160 to exert a restoring force on first spring end 164, and this in turn will cause the trigger 110 to return to its original position as the trigger 110 is released by the user.
Furthermore, the pulling of the trigger 110 causes the horizontal post 146 to move in the elongated slot 148 such that the horizontal post 146 engages walls of the elongated slot 148 and causes the second end 152 of the film producing mechanism 124 to pivotally move upward, thus causing the moveable dispensing ring 114 to swipe against the stationary application bar 154. With the release of the trigger 110, the torsion spring 160 causes the flat plate 142 to return to its original position, which in turn causes the second end 152 of the film producing mechanism 124 to return to a down position, which in turn causes the moveable dispensing ring 114 to return to a down position. This up-and-down movement of the moveable dispensing ring 114 causes the bubble solution delivered to the moveable dispensing ring 114 to be spread across the dispensing aperture 116 by the stationary application bar 154.

The battery compartment is designed with three (3) main goals. The first goal is to limit the amount of moisture and bubble liquid that can flow into the battery compartment, which is accomplished in this embodiment through the use of a sealed battery compartment, which is sealed to keep out liquids and moisture. The second goal is to have a safe chamber to house batteries. The third goal is to have the ability to insert batteries into the bubble toy device from the side rather than through the bottom.
In general, batteries have the ability to rapidly discharge and sometimes heat up. The kind of batteries used for the bubble toy device 100 are small and limited in power but still have the ability to overheat and/or rupture for chemical or electrochemical reasons. If a battery ruptures and bursts open, it can push into the ends of a battery compartment. Because the design of the battery compartment has the door on the side rather than the top or bottom, this design helps control and contain a battery failure where internal expansion occurs axially, thus not applying excess force to the battery door, but rather to the internal walls of the battery compartment. The batteries are small so that the impact of any break up can be contained within the bubble toy device 100.
The battery compartment has a side door that opens with a securing device 137, such as, for example, a screw (shown in
In another embodiment of this invention, the electromechanical pump 120, which is operated by the electric motor 121, is replaced by a purely mechanical pump 500 as shown in
