## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority from provisional U.S. Patent Application Ser. No. 60/630,530 entitled DYNAMIC DISPLAY FORMED WITHIN AN INFLATABLE filed in the name of William Machala on Nov. 23, 2004, the entirety of which is incorporated by reference herein.


FIELD OF THE INVENTION
The apparatus and method of the present invention relate to dynamic inflatable air displays that may be formed within a transparent enclosure and inflated through the use of a fan or other inflation device.
BACKGROUND OF THE INVENTION
Inflatable displays have become increasingly popular in recent years. These types of displays have a wide range of application, shape and size, including, but not limited to, figures for holiday and seasonal decoration, marketing, advertising, entertainment, and event attraction. The inflatable displays are made from a permeable fabric that allows air to pass through the fabric at approximately the same rate as the air being blown into the inflatable display. The process of continuously blowing air being supplied from a fan or other inflation device occurring at substantially the same rate as air escaping the fabric allows the display to maintain a three-dimensional shape without the use of an internal or external frame or structure. These are known in the industry as “cold-air” inflatable displays.
Typically, the cold-air inflatable display is a static figure formed from an inflation module which represents an individual figure when inflated. For example, a consumer may decide to decorate their house with a jack-o-lantern inflatable display for the Halloween season, a snowman inflatable display for the holiday season, or an Uncle Sam inflatable display for Independence Day. However, the inflatable display is generally a static element that is representative of a holiday or seasonal display. As such, typically, a figure is inflated to form a static display. There is no present apparatus or method utilizing a fan element or other inflation element to inflate an inflation module provided within an enclosure, wherein the fan element, the enclosure and the inflation module provide a dynamic display, as described herein.
SUMMARY OF THE INVENTION
The invention is directed to an inflatable display that has a first inflation module formed within a transparent enclosure. The inflation module is inflated by a fan element. More specifically, a first inflation module is formed from a permeable material and configured to represent a predetermined shape or design when inflated, such as a snowman, Santa Claus, Easter Bunny, Uncle Sam or any other type of holiday or seasonal display scene. The first inflation module is surrounded by a non-permeable material creating an enclosure forming a second inflation module.
According to an embodiment of the invention, a first inflation module is inflated in the shape of a snowman or other holiday or seasonal figure. The first inflation module is formed with at least one exhaust port in its base, which has two purposes. First, the exhaust port acts to inflate the second inflation module. Second, the exhaust port in the first inflation module acts in coordination with a mesh screen formed in the surface of the second inflation module to create an air flow within the enclosure. The second inflation module includes a plurality of small particles that are formed to look like snow or any other dynamic particles or objects appropriate for a holiday or seasonal display scene. Furthermore, the particles are created from a very light material and are carried by the air flows within the enclosure. Accordingly, an observer looking at the invention would visualize a snowing environment surrounding a snowman.

DETAILED DESCRIPTION OF THE INVENTION
The apparatus and method of the present invention will now be discussed with reference to FIGS. 1, 2, 3A-3E, 4 and 5. As first illustrated in FIG. 1, the invention is directed to an inflatable display unit 10. More specifically, according to an embodiment of the invention, inflatable display unit 10 will be discussed herein with regard to its component pieces that include first inflation module 30, enclosure 20 (second inflation module), fan element 35, lighting apparatus 40, and “snowflake” particles 50. An object of the invention is to implement first and second inflation modules, wherein the first is disposed within the second module. Furthermore, the second module is formed from a clear plastic material creating an enclosed operational environment. According to the invention, the air used to inflate the first and second modules is also used to agitate a plurality of polystyrene particles within the enclosure. Accordingly, an observer viewing the inflatable display would get the impression that it is snowing within the enclosure.
As illustrated according to one embodiment of the invention, first inflation module 30 is shown in the figures as a snowman. It is to be understood that while the figures illustrate a snowman, first inflation module 30 may be configured in any character, shape or size, depending on the specific need and purpose of the display. By way of example only, alternate embodiments of the invention may include such characters as Santa and/or Mrs. Clause, a reindeer, an Easter Bunny, Uncle Sam, or any type of seasonal or holiday character. Furthermore, it is to be understood that any number of inflation modules may be utilized to create the display and that any number or variety of inner-modules may be configured within one or more outer modules. Any number of fans corresponding to the number of inflation modules may also be utilized. In alternative embodiments, the inflatable device may include an inflatable city skyline or other tourist attraction that would parallel the typical liquid filled “snow globes” that are often sold to tourists.
First inflation module 30 is preferably made from a permeable fabric that allows air to escape at approximately the same rate as air being blown into the inflatable display 10 by fan element 35. Inflatable display 10 is held in position by a securing mechanism, such as, a ballast 55 situated at the bottom of enclosure 20 or a tether that fastens to either the ground or another structure and is secured to said inflatable display 10 by securing devices, such as a securing ring attached to inflatable display 10.
The inflatable display may include an interior lighting arrangement 40 that includes one or more light bulbs 41 secured to a power cord 43 and disposed within first inflation module 30. Protective covers 44 are secured around each light bulb 41 to protect the permeable fabric of first inflation module 30 from heat produced from each light bulb 41. Interior lighting assembly 40 is attached to fan assembly 35 through an electrical connector 45 on the bottom end of a power cord 46 that mates with fan assembly 35. Advantageously, if an operator does not want to illuminate the interior of the display, the operator may simply detach the electrical connector 45 from the fan assembly element to remove power from interior lighting arrangement 40, without necessarily removing lights 41 from the interior of the display.
As illustrated as reference character 50 in FIG. 1, “snowflake” particles may be formed as polystyrene particles, or a number of other light compact polymers. Polystyrene is discussed as a preferred embodiment because it is easily produced and readily available. More specifically, polystyrene is a strong plastic created from erethylene and benzene that can be injection molded, extruded or blow molded into any number of shapes and sizes. By way of example only, FIG. 2 illustrates three exemplary embodiments of the polystyrene implemented to represent the snowflakes.
However, it is to be understood that a wide variety of shapes/sizes of particles may be utilized corresponding to the holiday and/or seasonal display and based on design characteristics that include the size of the enclosure and/or the size/shape and configuration of the first inflation module or the size and power characteristics of the fan element in a given implementation. For example as shown in FIG. 2, in order to maximize the visual effect, packing peanuts 51 (the well-known filler used to fill and protect packages from being damaged during shipping) which are large oblong shaped pieces of polystyrene may be used. Alternatively, a smaller scale implementation may use hollow semi-spherical shaped polystyrene pieces 52 or even simple polystyrene pellets 53. The embodiments discussed herein are illustrative of possible implementations and a wide variety of shapes and sizes of polystyrene particles, or any other type of compact light particle may be implemented to represent very light particles, such as “snowflakes” 50.
As illustrated in FIG. 1, fan element 35 is preferably implemented as a lightweight plastic sleeveless bearing fan. The lightweight of the electric fan assembly and the plastic housing enables the fan assembly to be secured to the fabric of the inflatable display at a position elevated above the surface-touching bottom of the display without distorting the shape of inflatable display 10. Moreover, such an assembly inflates device 10 without the need for a base to support and elevate the fan above the ground to achieve sufficient air intake. Advantageously, fan element 35 can be easily removed from its respective housing for cleaning or replacement whenever necessary. Fan element 35 is covered with a safety grill to guard against unwanted debris from entering the display as well as contacting fan blades. Further, it is possible for fan element 35 to be configured with a variable air speed control, which provides a consumer the ability to adjust the degree of snowflake agitation. Also, depending on the actual implementation, the fan element may be configured with a stand that raises the fan element off of the ground.
Furthermore, as illustrated in FIG. 1, inflatable display 10 includes second inflation module 20 that creates a transparent enclosure around first inflation module 30. As shown, second inflation module 20 forms a transparent hollow sphere with an aperture allowing air intake tube 25 to connect first inflation module 30 with fan element 35. Second inflation module 20 is formed with at least one exhaust port 23. As illustrated in FIG. 1, exhaust port 23 is formed as a circular mesh screen. In order to prevent rain from entering enclosure 20, while maintaining the position of mesh screen 23, an air duct may be attached to the exterior side of mesh screen 23 at the top of the enclosure. The functionality of exhaust port 23 will be discussed in greater detail below with regard to FIG. 4. It is to be understood that depending on the actual implementation, the size, shape, configuration and number of exhaust ports 23 formed in the surface of second inflation module 20 may vary based on characteristics such as size of the second inflation module, the flow rate of air blown into inflatable device 10 by fan element 35, or any other number of design considerations.
Similarly, first inflation module 30 also has at least one exhaust port 33. As shown in FIG. 1, exhaust port 33 is formed in the base of first inflation module 30 to both agitate particles 50, as well as inflate second inflation module 20. Exhaust port 33 may be fitted with a screen in order to keep particles 50 from entering first inflation module 30. It is to be understood that the size, shape, configuration, and placement on the surface of first inflation module 30 may vary between implementations.
FIGS. 3A-3E illustrate the process of inflating inflatable device 10. As discussed above, fan element 35 forces air through air intake tube 25 into first inflation module 30. Because first inflation module 30 is made from a permeable material, air may leak from first inflation module 30 into second inflation module 20. Furthermore, first inflation module 30 is configured with at least one exhaust port 33 formed near the base of the module (FIGS. 3A-3E illustrate an exemplary embodiment of the invention implementing three exhaust ports), wherein exhaust port 33 directs a portion of the air from intake tube 25 directly into second inflation module 20.
FIG. 4 illustrates an air flow progression from a point in time wherein a fan element introduces air into the inflation device to a point in time wherein the air escapes through an exhaust valve formed in the enclosure according to an embodiment of the invention. For the purpose of illustration, the arrows with solid arrowheads 60 represent airflows either within first inflation module 30 or outside second inflation module 20, whereas arrows with hollow arrowheads 70 represent airflows within enclosure 20, but outside first inflation module 30.
Air is introduced from fan element 35, through air intake tube 25 and into first inflation module 30. The air enters second inflation module 20 primarily through exhaust port 33, but also to a lesser extent though the permeable surface of first inflation module 30. Although particles 50 are made of a light material, they are heavier than air and therefore accumulate around the base of the exterior of first inflation module 30. Accordingly, by configuring exhaust ports 33 around the base of the first inflation module, particles 50 are easily agitated by air exiting exhaust port 33.
Furthermore, second inflation module 20 has at least one mesh screen 23 formed at the top and/or the back of the enclosure. As discussed above, the second inflation module is formed from a non-permeable material. Accordingly, mesh screen 23 and exhaust port 33 act to create air flows within the enclosure. These airflows agitate the polystyrene particles that have accumulated around the base of enclosure 20 and guide them toward the top of the enclosure, where the particles subsequently fall back toward the base. The continuous airflow agitation/guiding process creates an effect that generates the impression of a snowfall to an observer watching inflated device 10 in operation.
FIG. 5 illustrates an air flow progression within a second embodiment of the invention wherein exhaust ports 33 formed in the base of first inflation module 30 are replaced with vacuum agitation ports 43. Air is introduced into the inflatable device via fan element 35 and air duct 25. The air inflates first inflation module 30 and then continues into a vacuum agitation port 43. The vacuum agitation port 43 directs the air flow into particle reservoir 55. Particle reservoir 55 collects particles after they have been agitated, as well as feeds agitation guide 75. Vacuum port 43 works in coordination with agitation guide 75 to bring the particles from particle reservoir 55 to the top of second inflation module 20 to dispersal point 70.
Although illustrative preferred embodiments have been described herein in detail, it should be noted and will be appreciated by those skilled in the art that numerous variations may be made within the scope of this invention without departing from the principle of this invention and without sacrificing its chief advantages. The terms and expressions have been used as terms of description and not terms of limitation. There is no intention to use the terms or expressions to exclude any equivalents of features shown and described or portions thereof and this invention should be defined in accordance with the claims which follow.
