Abstract
A bubble maker toy for producing a plurality of bubble streams from a liquid bubble solution. The bubble maker toy comprises a bubble wand and an electric fan. The bubble wand includes a plurality of bubble rings connected together by connection arms. The electric fan is configured for producing an airflow concentrated adjacent to the center of the bubble wand which forces the bubble streams outward from the center of the bubble wand and away from each other. The connection arms are arcuate in shape and connected to each other at approximately the center of the bubble wand causing the air flow produced by the electric fan to swirl in a rotating manner further forcing the bubble streams away from each other thus preventing the bubbles from sticking together or combining to form a cluster of bubbles.
Description
FIELD OF THE INVENTION
The present invention relates to bubble maker toys. More particularly, the present invention relates to bubble maker toys for simultaneously producing a plurality of bubble streams.
BACKGROUND INFORMATION
The art of making bubbles from a soap solution is a well-known form of entertainment. Typically, a bubble wand having a generally circular bubble ring at one end of the wand is immersed in a soap solution or the like of suitable viscosity and surface tension to create an adherent layer of soap solution. The soap solution forms a film which typically spans the entire inner area of the bubble ring. The bubble ring is then blown against to create bubbles. One disadvantage of this technique is that when a user blows against the bubble ring, a user must place his mouth on or about the bubble ring. This is a problem, particularly when there are many users operating the device, because it promotes the spread of germs among users.
Bubble maker toys have been made that provide a fan for producing an airflow against the bubble wand. However, these fans are typically made of a hard plastic material that presents additional safety concerns. For example, a child using the toy could stick his finger in the fan blades while they are rotating causing injury to the child's fingers.
Prior art bubble maker toys have been made which have multiple bubble rings on a single bubble wand for producing multiple bubbles simultaneously. Additionally, bubble maker toys have been produced which create a stream of bubbles. However, problems are encountered when attempting to produce multiple bubble streams. Such problems include having the multiple bubbles stick together or combine to form one cluster of bubbles.
Thus, there is a need for a bubble maker toy having an improved, safe air flow means. There is also a need for a bubble maker toy that can produce multiple streams of bubbles simultaneously and which retains their separate integrities.
SUMMARY OF THE INVENTION
The bubble maker toy of the present invention satisfies these needs and other needs. A bubble maker toy according to the present invention is configured for simultaneously producing a plurality of bubble streams from a liquid bubble solution. The bubble maker toy comprises a bubble wand having a center and an outer circumference, the bubble wand including a plurality of bubble rings arranged around the outer circumference, and air flow means for producing an air flow across the bubble wand and through the bubble rings.
The bubble solution is of suitable viscosity and surface tension to cling to the bubble wand forming films across the bubble rings. The air flow across the bubble wand and through the bubble rings produces bubble streams from the bubble solution. The air flow means is configured for producing an air flow which forces the bubbles streams outward from the center of the bubble wand and away from each other preventing them from sticking together or combing to form one cluster of bubbles.
The airflow means is configured for producing an air flow which is concentrated adjacent to the center of the bubble wand. The bubble wand further comprises connection arms which connect the bubble rings together. The connection arms are arcuate in shape and are connected to each other at approximately the center of the bubble wand. The air flow produced by the air flow means flows across the connection arms causing the air flow to swirl in a rotating manner further forcing the bubble streams outward from the center of the bubble wand and away from each other. Preferably, the bubble rings and connection arms include ridges which form reservoirs for holding the bubble solution.
The airflow means comprises an electric fan having a plurality of fan blades configured to rotate about a central axis. The fan blades include upper, outer edges which curve inward toward the central axis for producing the airflow concentrated adjacent to the center of the bubble wand. The bubble wand is positioned adjacent to the fan blades with the bubble rings positioned adjacent to the upper, outer edges of the fan blades. Preferably, the fan blades are comprised of a soft foam material for preventing injuries to the toy user's fingers.
The bubble maker toy further comprises a housing having a handle. The electric fan and bubble wand are connected to said housing. Two activation switches are included for activating the electric fan. The activation switches are positioned on opposite ends of the handle so that the bubble maker toy can be easily operated by both right- and left-handed users.
A bubble solution dipping dish is included for holding the bubble solution. In operation, the bubble wand is dipped into bubble solution held in the dipping dish prior to activating the electric fan. The dipping dish includes a sidewall having a pouring spout for returning unused bubble solution to a storage container.
Further objects, features and advantages of the present invention will become apparent from the following description and drawings.

and through the bubble rings
18
.
The housing
16
includes a handle
17
, a motor enclosure
28
for motor
24
and a bubble wand mounting section
30
. Preferably, the bubble wand mounting section
30
is circular in shape. The motor enclosure
28
, is connected to the bubble wand mounting section
30
by spokes
31
and is in approximately the center and below the bubble wand mounting section
30
. Spokes
31
form a fan blade cage. Preferably, the housing
16
is made of a molded plastic material, however other suitable materials or manufacturing processes may be used.
The fan blade assembly
25
is connected via shaft
23
to the electric motor
24
such that the fan blades
26
are positioned in the fan blade cage to rotate in approximately the same plane as the bubble wand connection section
30
with the upper, outer edges
29
of the fan blades
26
extending beyond the bubble wand connection section
30
. The upper, outer edges of fan blades
26
preferably move closely adjacent to but spaced from the bubble rings
18
. The bubble wand
12
is connected to the bubble wand connection section
30
by posts
32
formed integrally with the bubble wand
12
. The posts
32
extend through spacers
34
into apertures in the bubble wand section
30
. Fasteners, such as threaded screws
36
, are used to secure the bubble wand
12
to the mounting section
30
. The spacers
34
fit between the bubble wand
12
and the bubble wand mounting section
30
to hold the bubble wand
12
a predetermined distance away therefrom. In the preferred embodiment, the bubble wand
12
is spaced ½ inch from the bubble wand mounting section
30
.
In the preferred embodiment, the bubble wand
12
comprises a molded plastic material, however other suitable materials or manufacturing processes may be used to make a bubble wand
12
according to the present invention. The bubble wand
12
includes six bubble rings
18
arranged around the outer circumference of the bubble wand
12
in a circular pattern. Three connection arms
20
connect the six bubble rings
18
together. The three connection arms
20
connect to each other in approximately the center of the bubble wand
12
adjacent to and centered relative to the central hub
27
of the fan blade assembly
25
. Each connection arm
20
includes a connection stub
21
, which is used, inter alia, for connecting the bubble wand
12
to the housing
16
. The posts
32

21
substantially perpendicular to the plane of the bubble wand
12
.
In the preferred form shown in the drawings, the connection arms
20
comprise first segments
20
A and second segments
20
B. It is the first segments
20
A which are connected and formed to each other adjacent the center of the bubble wand
12
. Segments
20
A extend outwardly and terminate at a first set of bubble rings
18
. The second segments
20
B are joined to respective ones of the first set of bubble rings
18
and extend to respective ones of the second set of bubble rings
18
. In this manner, all of the bubble rings
18
are connected to each other. As shown, connection stubs
21
project outwardly from the first and second sets of bubble rings
18
.
It will also be apparent from the drawings that the motor
24
drives the fan blades
26
in a clockwise direction, which is in the same direction as the arcuate connection arms
20
are arched. To produce the most effective swirling airflow pattern and repeated streams of bubbles the relationship of the curvature of the connector arms
20
and fan blade
26
direction should be as shown. If the fan blades
26
are to move in a counterclockwise direction, then the curvature of the connector arms
20
should be reversed so that the connector arm curvature is in the same direction as the fan blades
26
are driven.
In the preferred embodiment, the bubble rings
12
have an inner diameter of ¾ inch and an outer diameter of 1¼ inches. The centers of the bubble rings
12
are positioned approximately 2 inches from the center of the bubble wand
12
and approximately 2 inches from the adjacent bubble ring centers. The connection arms
20
are approximately ½ inch wide.
The housing handle
17
includes a battery compartment and textured grip
38
. In the preferred embodiment, the battery compartment is configured to hold four AA (1.5 v) batteries, which are electrically connected to the electric motor
24
, for powering the motor
24
. A pair of activation switches
40
is positioned one each at opposite ends of the handle
17
. The activation switches
40
are electrically connected to the electric motor
24
and are configured for activating the electric motor
24
which causes the fan blades
26
to rotate creating an air flow through the bubble wand
12
and through the bubble rings
18
, as described in more detail below. By placing the activation switches
40
at opposite ends of the handle
17
, the bubble maker toy
10
can be easily operated by both right- and left-handed users and whether it is gripped palm up or palm down.
A dipping dish
42
may be provided for holding the bubble solution. In the preferred embodiment, the dipping dish
42
comprises a circular flat dish slightly larger than the bubble wand
12
. The dipping dish
42
has a raised sidewall
44
which includes a pouring spout
46
for returning unused bubble solution to a storage container. Preferably, the dipping dish
42
is made of a molded plastic material, however other suitable materials and manufacturing processes may be used. Whereas here the bubble wand has an outside diameter of about 6½ inches in the preferred embodiment, the dipping dish
42
has a diameter of approximately 7 inches and the sidewalls
44
are approximately ⅞ inches high.
In operation, bubble solution, such as a soap solution, is dispensed into the dipping dish
42
. As shown in
FIGS. 1
,
2
and
5
, the bubble maker toy
10
is then placed in the dipping dish
42
with the bubble wand
12
face-down such that the bubble wand
12
is immersed in bubble solution. The bubble solution, which is of a suitable viscosity and surface tension to create an adherent layer on the bubble wand
12
, clings to the bubble wand
12
as the bubble wand
12
is removed from the dipping dish
42
.
The bubble solution forms a film on the bubble wand
12
covering the inner area of each bubble ring
18
. The spaces between the raised ridges
22
form reservoirs that store additional bubble solution. Once the bubble maker toy
10
is removed from the dipping dish
42
, the bubble wand
12
is preferably turned face-up and the electric fan
14
is activated by pressing one of the activation switches
40
.
Activation of the electric fan
14
causes the fan blades
26
to rotate creating an air flow through the bubble wand
12
and through the bubble rings
18
. As air flows through the bubble rings
18
, the bubble solution films fill with air and break away from the bubble rings
18
forming bubbles. As bubbles break away from the bubble rings
18
, the stored bubble solution is drawn from the reservoirs formed by the raised ridges
22
on the bubble rings
18
and connection arms
20
to form additional films on each bubble ring
18
. These additional films also fill with air and form bubbles. In this manner, bubble streams are produced by each of the bubble rings
18
until substantially all of the bubble solution transferred to the bubble wand
12
during dipping has been used.
Due in part to the shape and configuration of the fan blades
26
, particularly the inwardly curved upper, outer fan blade edges
29
, the air flow generated by the electric fan
14
tends to concentrate in the area adjacent to the central hub
27
of the fan blade assembly
25
and center of the bubble wand
12
. The shape of the connection arms
20
causes the airflow to swirl in a rotating manner. This swirling airflow pattern and the effect of the fan blade configuration forces the bubble streams outward from the center of the bubble wand
12
and away from each other. In this manner, the bubble streams are prevented from sticking together or combining to form one cluster of bubbles. Additionally, the bubble streams are blown in an entertaining swirling pattern by the airflow.
It will be apparent to those skilled in the art that modifications may be made without departing from the spirit and scope of the invention. Accordingly, it is not intended that the invention be limited except as may be necessary in view of the appended claims.
