This application claims the benefit of U.S. Provisional Patent Application No. 62/060,559 filed Oct. 6, 2014, the entire content of which is hereby incorporated by reference.


FIELD OF THE TECHNOLOGY
The present patent application generally relates to a decoration device, and particularly to a decoration device with projection images for holidays, festivals and parties.
BACKGROUND
There are illuminated novelties for parties, holidays and festivals such as Halloween, Christmas, and Easter For example, there are illuminated novelties such as Halloween Jack-'O-Lanterns that may be made and used as decoration. Traditionally, a lot of people like to decorate their porches or their houses with pumpkin decorations for Halloween. Pumpkin carving is a popular event for kids, by removing the soft pulp of a pumpkin, carving side openings representing eyes, nose and mouth of the pumpkin and placing a candle inside the hollow pumpkin to light up the carved openings and the pumpkin head, which is commonly called Jack-'O-Lantern. However, real pumpkin decorations are perishable and can't be displayed for a long time. Therefore, artificial Jack-'O-Lanterns have been developed which are made of different materials, such as ceramic, Polyresin, PU foam, Paper Mache, Styrofoam or plastic materials. Some of these artificial pumpkins are known to have electric lights or battery-operated light bulbs to replace candles as a light source inside the pumpkin.
Both real pumpkin and artificial pumpkins are limited to one carved face or one molded face only. Since the face is either carved or molded on the pumpkin, so the face cannot be changed unless you buy a new one or carve another real pumpkin.
Some of the decoration pumpkins may come with sound and light, but the sound is pre-recorded in IC chip which is usually very short and the sound quality is not very good, and people do not have a choice on the music or sound playback from the pumpkin decoration.
There is a desire to produce a decoration device which can project various images on the surface of the device or even on a wall for holidays, festivals and parties.
The above description of the background is provided to aid in understanding the decoration device with projection images, but is not admitted to describe or constitute pertinent prior art to the decoration device with projection images, or consider the cited documents as material to the patentability of the claims of the present application.

In accordance with an embodiment of the present patent application, FIGS. 1-6 provide different views of the illuminated pumpkin decoration with different configurations of the projection device. As shown in these figures, the illuminated pumpkin may include the following parts: a pumpkin shaped shell 22, a module 34 and a projection unit 1, or a dome-shaped projection unit 27, or a rotatable cylinder-shaped projection unit 38. It is understood that the projection unit may in any other shape.
The pumpkin shell 22 may be made of plastic, vinyl or other rigid materials. The pumpkin shell 22 should be shaped like a real pumpkin. There is an opening at the bottom of the pumpkin shell 22 for installation of the module 34.
The pumpkin shell 22 may also include recessed depressions or cut out holes representing the face of a Jack-'O-Lantern pumpkin. If recessed depressions are applied on the pumpkin shell 22, fabric or paint may be attached or painted on the recessed area to represent eyes, nose and mouth of a Jack-'O-Lantern. The painted or fabric covered area will cover the light when lights inside the pumpkin shell 22 are on and then generate a silhouette or an image of a Jack-O-Lantern face. When cut out holes are applied to the pumpkin shell, the cut out area allows light to shine through the holes. When lights inside the pumpkin shell 22 are on, then it generates an illuminated Jack-'O-Lantern face as the interior light source is shining through the holes.
Both recessed depressions and cut out holes create a permanent face on the pumpkin shell 22, but that face cannot be hidden, removed or changed.
The present patent application provides several embodiments of a pumpkin shell 22 with hidden face or image inside. The pumpkin shell 22 can be made to look just like an ordinary pumpkin decoration. No one would know what's inside until the lights inside the pumpkin shell 22 are turned on. LED fixed on the projection unit 1 may work as a light source to project a projected image 23 onto the pumpkin shell 22 from its interior. The image on projection film can be projected onto the pumpkin shell 22 and can generate an illuminated face or an illuminated image, which can be visible from outside the pumpkin shell 22. FIG. 1 shows the projected image 23 on the pumpkin shell 22 and FIG. 2 shows the pumpkin shell 22 without any projected image.
In addition to the pumpkin shell 22, the present patent application also includes a module 34 which may be attached to the opening at the bottom of the pumpkin shell 22, as shown in FIGS. 3-6 and FIG. 28. The module 34 includes two main sections, namely a projection section and a power controller section.
The projection section can be configured in five different options/embodiments:
Embodiment 1
The projection section can be configured as a projection unit 1 to hold a rectangle projection film 26 (see FIGS. 4-5).
In this case, module 34 can be configured to hold the rectangle projection film 26. Referring to FIG. 7, the module may include the following parts: an outer housing 5, a projection unit 1, an inner housing 6, a module base 16, a battery compartment 12 and a speaker 11 (for the function of playback music or sound). FIG. 7 is a comprehensive drawing of module 34 which may be configured to hold the rectangle projection film 26. FIG. 8 is the general assembly drawing of the construction of the module 34.
No matter which projection unit is used or configured on the module 34, the present patent application provides an embodiment to allow people to change the projection image inside the pumpkin without using any tools.
FIG. 8 also shows how this module 34 can be assembled and the general concept of making the projection film replaceable without using any tools.
Outer housing 5 may be a fixture to be attached to the bottom of the pumpkin shell 22 by using screws or any kind of adhesive glue. As shown in FIGS. 7-8 and FIGS. 11-14, the projection unit 1, inner housing 6, module base 16, battery compartment 12, battery compartment door 13 and speaker 11 can be attached together by screws or any other locking means. As shown in FIGS. 11-14, the projection unit 1 can be connected to the module 34 by frictionally engaging two hinge rods 2 in two c-shaped openings formed on two hinge rod-holding stands 3 on the module 34 respectively. The inner housing 6 can be attached to the power controller section to hold both hinge rods 2 securely onto the hinge rod-holding stands 3 and then form a hinged construction which can allow a user to adjust the projection angle. As a result, the user can adjust the projected image to the desired location on the pumpkin shell 22 by tilting the projection unit 1. Tilting the projection unit 1 up can move projected image 23 to a higher position on the pumpkin shell 22, and tilting the projection unit 1 down can move the projected image 23 to a lower position on the pumpkin shell 22. It is understood by one skilled in the art that the hinge construction can be in the form of any other possible hinge mechanism.
Projection unit 1 can be used to hold the rectangle projection film 26. FIGS. 23-26 are examples of different rectangle projection films 26 with different transparent images 30, 31, 32, 33, which can be placed at the front side of the projection unit 1 (as shown in FIG. 27). It is possible that the image 30, 31, 32, 33 is not transparent, whereas the area around the image 30, 31, 32, 33 is transparent. It is also possible that the image 30, 31, 32, 33 is transparent, whereas the area around the image 30, 31, 32, 33 is not transparent. It is also possible that the image 30, 31, 32, 33 can be a cut-out hole or silhouette where light can shine through the hole or the silhouette to project the desire image on the pumpkin shell 22 from its interior. Film holders 4 can be formed on the front edges of the opening of projection unit 1 to hold the rectangle projection film 26. Users can replace the projection film by pulling out the old one and sliding in a new one. After the film is securely fastened on the projection unit 1. The users can put the whole module 34 back in the pumpkin shell 22 by a simple process. The users can insert the module 34 through the opening on the bottom of the pumpkin shell 22.

A transparent image 29 can be provided on the dome-shaped projection unit 27. It is possible that the image 29 is not transparent, whereas the area around the image 29 is transparent. It is also possible that the image 29 is transparent, whereas the area around the image 29 is not transparent. It is also possible that the image 29 can be a cut-out hole or silhouette where light can shine through the hole or the silhouette to project the desire image on the pumpkin shell 22 from its interior. The transparent image 29 on the dome-shaped projection unit 27 can be changed by changing to another dome-shaped projection unit 27 with a different transparent image on the dome-shaped projection unit. Users can choose the one with a face design to project the face illusion on the pumpkin shell 22 or the one with various graphics all over the dome-shaped projection unit 27 to project graphics on to the whole pumpkin shell 22 from its interior.
As shown in FIGS. 7-10, a battery compartment 12 may be provided to hold three AA batteries which can serve as a power supply of the module 34. A speaker cavity 17 may be provided to hold a speaker 11. The device will be able to playback music or sound if the speaker 11 is installed.
As shown in FIG. 12 and FIG. 14, the module 34 can also be configured to use Li-Polymer rechargeable battery. If Li-Polymer rechargeable battery is used, there should be a micro USB port 21 provided for the purpose of charging the battery. Rechargeable battery can be recharged by connecting the module 34 to a USB charger or a USB port on a computer via a USB charging cable.
Both AA batteries in the battery compartment 12 and Li-Polymer rechargeable battery can provide power to light up LED 24 in the dome-shaped projection unit 27 to work as a light source in the projection unit. Once the light source is on, it will project the projected image 23 on the pumpkin shell from its interior.
If Bluetooth® technology is used, the speaker 11 can play the music or sound effect once the device is successfully connected to any mobile device via the Bluetooth® technology.
If an integrated circuit (IC) is used, the speaker 11 can playback pre-recorded music or sound stored in an IC chip.
Embodiment 3
The projection section can be configured as a rotatable cylinder-shaped projection unit 38 (See FIG. 6, FIG. 31 and FIG. 33).
In this configuration, module 34 can be configured to hold a rotatable cylinder-shaped projection unit 38. It may include the following parts: an outer housing 5, a cylinder-shaped projection unit 38, an inner housing 6, module base 16, battery compartment 12 and speaker 11 (for the function of playback music or sound). FIG. 6 is a drawing of the module 34 which can be configured to hold a rotatable cylinder-shaped projection unit 38.
The cylinder-shaped projection unit 38 can be rotatable, so users can change the projection image by turning a switch 40 located at the bottom of the module 34.
FIG. 32 are examples of different projection films 39 with different transparent images, which can be placed into the cylinder-shaped projection unit 38 (as shown in FIG. 31).
The cylinder-shaped projection unit 38 may have an opening 41 at the front. An LED light may be fixed inside the cylinder-shaped projection unit 38. The LED may serve as a light source inside the cylinder-shaped projection unit 38. When the LED is turned on and it works as a light source to project the image printed on the projection film 39 onto the pumpkin shell from its interior.
To change the projection image under this configuration, users do not have to take the whole module 34 out. People can easily change the projection image by turning the switch 40 at the bottom of the module 34. Gear 35 and a spinning plate in the cylinder-shaped projection unit 38 may be connected with a shaft 37. Gear 36 and the switch 40 may be connected by another shaft 37′. When a user turns the switch 40 clockwise, gear 36 will turn clockwise and drive gear 35 to turn anti-clockwise. Since gear 35 and a spinning plate in the cylinder-shaped projection unit 38 are connected, so the spinning plate will also turn anti-clockwise. As a result, the projection film 39 fixed on the spinning plate will be rotated anti-clockwise. If another face or graphic printed on the projection film 39 is rotated to the location where the light source can shine through the projection film 39 and the opening 41, then it will project another face or graphic illusion onto the pumpkin shell from its interior.
As shown in FIGS. 7-10, a battery compartment 12 may be provided to hold three AA batteries which can serve as a power supply for the module 34. A speaker cavity 17 can be provided to hold a speaker 11. The device will be able to playback music or sound if the speaker 11 is installed.
As shown in FIG. 12 and FIG. 14, the module 34 can also be configured to use Li-Polymer rechargeable battery. If Li-Polymer rechargeable battery is used, there should be a micro USB port 21 provided for the purpose of charging the battery. Rechargeable battery can be recharged by connecting the module 34 to a USB charger or a USB port on a computer via a USB charging cable.

As another embodiment of a rotatable cylinder-shaped projection unit 38 (See FIGS. 34-38) this option provides users an option to switch the projection image by pressing a button on the bottom of the module base 16.
In this configuration, module 34 can be configured to hold a rotatable cylinder-shaped projection unit 38. It may include the following parts: an outer housing 5, a cylinder-shaped projection unit 38, an inner housing 6, module base 16, button 42, shaft connector 43, shaft 44, joint 45, four-side film holder 46, spring 47, star gear 48, battery compartment 12 and speaker 11 (for the function of playback music or sound). FIG. 34 is a drawing of the module 34 which can be configured to hold an automatic rotatable cylinder-shaped projection unit 38.
The cylinder-shaped projection unit 38 can be rotatable, so users can change the projection image by pressing the button 42 located at the bottom of the module 34.
FIG. 32 are examples of different projection film 39 designs, which can be placed into the cylinder-shaped projection unit 38 (as shown in FIG. 31).
The cylinder-shaped projection unit 38 may have an opening 41 at the front. An LED light may be fixed inside the cylinder-shaped projection unit 38. The LED may serve as a light source inside the cylinder-shaped projection unit 38. When the LED is turned on and it works as a light source to project the image printed on the projection film fixed on the four-side film holder onto the pumpkin shell from its interior. It is possible that the image is not transparent, whereas the area around the image is transparent. It is also possible that the image is transparent, whereas the area around the image is not transparent. It is also possible that the image can be a cut-out hole or silhouette where light can shine through the hole or the silhouette to project the desire image on the pumpkin shell 22 from its interior.
To change the projection image under this configuration, users do not have to take the whole module 34 out. Users can easily change the projection image by pressing a button 42 at the bottom of the module 34, as shown in FIGS. 34, 35, 35a and 36. When the button 42 is pressed, a shaft connector 43, which may be connected with the button 42, is moved in a direction towards a biasing spring 47 to thereby compress the spring 47. The spring 47 may be mounted on a rod 45, which may be connected to one side of the shaft connector 43 opposite to the button 42. When the shaft connector 43 is moved, a pointy tooth 49 provided thereon can engage with a 4-tooth gear 48, which may be mounted on a lower end of a central shaft 44 provided on the four-sided film holder 46. When the button 42 is pressed, the 4-tooth gear 48 will rotate forty-five degrees anti-clockwise by the pointy tooth 49, and the shaft 44 will also rotate forty-five degrees anti-clockwise. Then, the four-sided film holder 46, which is connected to the shaft 44, will rotate forty-five degrees. As a result, an adjacent side of the four-sided film holder 46 will be facing the opening 41. The image on that adjacent side of the four-sided film holder 46 will then be the image to be projected from the projection unit. Since the spring 47 is mounted on the rod 45, which is connected with the shaft connector 43, the shaft connector 43 will return to its original position under the biasing force of the spring 47 when the button 42 is not being pressed. The shaft connector 43, when returned to its original position, is configured to hold the 4-tooth gear 48 in place until the button 42 is pressed again.
As shown in FIGS. 7-10, a battery compartment 12 may be provided to hold three AA batteries which can serve as a power supply for the module 34. A speaker cavity 17 may be provided to hold a speaker 11. The device will be able to playback music or sound if the speaker 11 is installed.
As shown in FIG. 12 and FIG. 14, the module 34 can also be configured to use Li-Polymer rechargeable battery. If Li-Polymer rechargeable battery is used, there should be a micro USB port 21 provided for the purpose of charging the battery. Rechargeable battery can be recharged by connecting the module 34 to a USB charger or a USB port on a computer via a USB charging cable.
Both AA batteries in the battery compartment 12 and Li-Polymer rechargeable battery can provide power to light up the LED in the cylinder-shaped projection unit 38 to work as a light source in the projection unit. Once the light source is on, it will project the projected image 23 on the pumpkin shell from its interior.
If Bluetooth® technology is adopted, the speaker 11 can play the music or sound once the device is successfully connected to any mobile device via the Bluetooth® technology.
If integrated circuit (IC) is used, the speaker 11 can playback pre-recorded music or sound effect stored in an IC chip.
