DETAILED DESCRIPTION OF THE INVENTION

As seen in FIGS. 1 through 6, the preferred embodiment of the present invention is a toy 10 having a removably coupled night-light 20. The night-light 20 includes vast improvements over prior art night-lights by adding projection features with light emitting diodes (LEDs), thereby utilizing optic technology to display a unique image or design on a wall, ceiling or other pre-determined surface.
As is best appreciated from FIGS. 1 and 2, the night-light 20 is removably housed within the stuffed plush toy 10. The toy 10 includes a main body 12, including a substantially rectangular interior cavity 14, centrally positioned within the toy and created from the removal of plush stuffing, which preferably extends throughout the main body 12 from a top surface 12A to a bottom surface 12B. Both the top and bottom surfaces 12A, 12B of the main body 12 of the toy include an interior rectangular edge 12C, 12D which define the perimeter of the interior cavity 14. In one embodiment, a fold-over flap 16 is coupled to the bottom surface 12B of the toy 10 and includes a hook and loop fastener 16A for removably covering the interior cavity 14 along the bottom surface 12B of the toy 10.
Referring to FIG. 3, the night-light 20 includes a substantially rectangular light box housing 22 having an integrally coupled grated top cover 24. The housing, preferably made of plastic, is substantially rectangular and includes a top end 22A, a bottom end 22B and an interior cavity 22C. The grated top cover 24 has a perimeter 26, which overhangs the top end 22A of the housing 22. The grated top cover 24 is concave and preferably plastic and includes a plurality of openings 28 of desired shapes and designs, including a moon 28A, stars 28B, and unicorn 28C. Each opening and shape is designed to allow light to pass therethrough from the LED(s) and project a clear design or shape on the ceiling or wall. A variety of other shapes and designs are contemplated herein, as is the use of interchangeable covers, and the use of specific designs within the preferred embodiment is for illustrative purposes only and not to be limited or narrowly construed.
The night-light 20 is further comprised of an exterior casing 30, a top bracket 40, and a bottom bracket 42, all preferably made of plastic, which secure the light box housing 22 of the present invention within the interior cavity 14 of the toy 10. The exterior casing 30 is a substantially rectangular cage, having an open top end 30A and an open bottom end 30B. The open top end 30A defines a top rim 30C, while the open bottom end 30C defines a bottom edge 30D and together are specially designed to accept the light box housing 22 therein. The housing 22 is securable to the casing 30 by means of a screw 32 and preferably snaps 36. At least one, preferably four snap receiving receptacles 38 are positionable within the interior cavity 22C of the housing 22 near the top end 22A for accepting the snaps 36 of the casing 30. However, other like fastening means is contemplated and interchangeable.
The casing 30 is positionable within the interior cavity 14 of the toy 10 and secured by means of the brackets 40, 42. In particular, once the casing is positioned within the cavity 14, the bottom bracket 42 is positioned adjacent the bottom surface 12B of the toy 10 and couples to the bottom edge 30D of the exterior casing 30, by screws 32A or other like fastening means. Thus, the rectangular edge 120 of the bottom surface 12B of the plush toy 10 is sandwiched between the bottom bracket 42 and the bottom edge 30D of the casing 30. Similarly, the top bracket 40 is positioned adjacent the top surface 12A of the toy 10 and couples to the top rim 30C of the exterior casing 30 by screws 322 or other like fastening means. Thus, the rectangular edge 12C of the top surface 12A of the toy 10 is sandwiched between the top bracket 40 and the top rim 30C of the casing 30. Preferably, screws 32 are accepted through predefined holes 34 in the top and bottom brackets 40, 42 and secure within predetermined recesses 35 in the exterior casing 30. In addition, a pair of side clips 40A of the top bracket 40 integrally fastens underneath the top edge 30C of the casing 30, within corresponding and predefined clip receiving recesses 30E, for further securing the casing 30 within the interior cavity 14.
After the casing 30 is secured within the interior cavity 14 of the toy 10, the light box housing 22 is accepted and secured within the casing 30. Specifically, the bottom end 22B of the housing 22 is accepted through the casing 30 and snaps into positioned within the open bottom end 30B, by snapping means 36, 38. In particular, the snaps 36 of the casing 30 are accepted within the snap receptacles 38 of the housing 22. The design allows a user access to the bottom end 22B of the housing 22 through the fold-over flap 16 along the bottom surface 12B of the toy 10. The grated top cover 24 extends over the entire housing 22 and casing 30 such that the perimeter 26 overhangs and hides the top bracket 40 from view.
To remove the housing 22 from the casing 30, a user pushes upwardly on the bottom end 22B of the housing 22 and unsnaps the snaps 36 of the casing 30 from the receptacles 38 of the housing, thereby releasing the housing 30 and integrated grated top cover 24 from the casing 30.
As best illustrated in FIGS. 4 and 5, the light-box housing 22, houses the projection components, accessories, electrical circuitry and power source required for projecting an image or design onto the ceiling or wall. The projection components include light emitting diodes (LEDs) arranged on a circuit board. Generally, at least one light emitting diode 50 is present, but as illustrated in the preferred embodiment, three LEDs 50 are desired. Specifically, one yellow LED 50A, one blue LED 50B, and one green LED 50C are present. However, other colors are contemplated herein. In the projection night-light 20, the LEDs 50 are connected with circuitry means such as, for example, the printed circuit board 60, a sensor button 62, conductive means 64, AC jack 66, and integrated circuit 70. In addition, the integrated circuit 70 includes a timing means and a timing switch 72 to provide desired light functions and effects.
The interior cavity 22C of the housing 22 includes the printed circuit board (PCB) 60 which is secured therein by screws 68 which are screwed therein through corresponding screw holes 60A. The grated top cover 24 includes the metal sensor button 62 in electrical contact with the power source. The sensor button 62 is in communication via means of conductive wires 64, with the PCB 60. The PCB 60 includes at least one, preferably three, apertures 603 about which is formed conductive sockets 60C for holding the LEDs 50 therein.
Positionable underneath the PCB 30 is a battery holder compartment 80, preferable for supplying voltage to the night-light 20 of approximately 4.5 volts utilizing a DC power source. Different power source compartments and configurations are contemplated, including an arrangement that supplies different voltages. In addition, alternative power sources are contemplated herein which include, but are not limited to, solar power, wind power, chemical power, alternative DC power sources, rechargeable batteries, AC adapters with jack and power, or alkaline batteries. The compartment 80 includes spacers 82 for holding one or more batteries as necessary. A fastening door 84 provides closure for the battery holder compartment 80, and is preferably locked in position by a screw 86.
While a child can manually illuminate and darken the LEDs 50 by depressing the sensor button 62, the toy 10 is preferably provided with a timing means within the integrated circuit 70, actuated by the timing switch 72, for automatically de-energizing the LEDs 50 after a predetermined amount of time. Adjacent the battery holder compartment 80 is the timer switch 72. The switch 82 has two positions, the on position 72A for turning the circuit function on, and an off position 72B for turning the circuit function off.
The circuitry of the PCB 60 is further illustrated in FIGS. 4 through 6. The circuit preferably includes, but is not limited to, a combination of the following electric components including the sensor button 62, conductive wires 64, PCB 60, integrated circuit 70, and other electric components selected from those conventionally available, which work in connection to allow a child to push the sensor button 62 and automatically actuate the projection night-light 20. These electric components are particularly arranged to allow the LEDs 50 to project desired light designs, shapes and sequences onto the ceiling or wall.
The integrated circuit (IC) 70, preferably an IC chip, is utilized for the ability to provide a plurality of functionality selected from those available light functions, but improved to include otherwise unique child-like projection design functions. In particular, the integrated circuit 70 includes the timing means in communication with the timing switch 72. When the switch 72 is in the on position 72A, the timing means of the integrated circuit 70 is actuated, and when a child depresses the sensor button 70, the circuit will continue to power the LEDs 50 according to predetermined sequences for a predetermined amount of time before automatically turning the LEDs 50 off. When the switch 72 is in the off position 72B, the timing means of the integrated circuit is interrupted, and the sensor button 62 manually controls illuminating of the LEDs 50, rotating through illumination of the LEDs 50, before turning all the LEDs 50 off.
The PCB 60 and IC 70 generally function after the sensor button 62 is depressed, by immediately and automatically turning on one of the LEDs 50. Preferably, when the switch is in the off position 72B, manual functionality is engaged, and thus when the sensor button 62 is depressed for the first time the yellow LED 50A illuminates and remains illuminated. If the sensor button 62 is depressed again, the yellow LED 50A turns off, and simultaneously, the blue LED 50B is turned on. If the sensor button 50 is depressed for a third time, the blue LED 50B is turned off, and simultaneously, the green LED 50C is turned on. If the sensor button 50 is depressed for a fourth time, the green LED 50C will turn off and all lights will remain off.
When the switch 72 is in the on position 72A, and a child activates the sensor button 62, the yellow LED 50A automatically illuminates. A rotating sequence then automatically follows for a predetermined amount of time, after which the circuit will automatically turn off all the LEDs 50. The automatic sequence includes rotating between illuminating yellow LED, blue LED and green LED light, pausing at each color for a period of approximately 8 seconds, before fading the light and changing to the next color in sequence. The rotation continues until the time stops. The timing means of the integrated circuit 70 may be set for a period of 20 minutes, longer or shorter, depending on the desired needs of the child. Preferably, the child will actuate the sensor button 62, which will illuminate light in the above-mentioned sequence, and project the design or shapes on the ceiling or wall until the child falls asleep. After which, the circuit 70 and LEDs 50 will automatically turn off. Should the child depress the sensor button 62 again while the timing switch 72 is in the on position 72A, the timing means of the IC 70 will interrupt and thus the rotating sequence will automatically stop and manual functionality will resume, wherein the yellow LED 50A will illuminate and stay illuminated indefinitely. As discussed above, if the sensor button 62 is depressed again, the yellow LED 50A turns off, and simultaneously, the blue LED 50B is turned on. If the sensor button 62 is depressed yet again, the blue LED 50B is turned off, and simultaneously, the green LED 50C is turned on. If the sensor button 62 is depressed yet again, the green LED 50C will turn off and all LEDs 50 will remain off.
Referring to FIG. 6, the sensor button 62 is in communication with the batteries 88 within the battery holder compartment 80, as well as being connected through a diode 92A, to a zener diode 92B, then through capacitors 94A and a resistor 96A to the integrated circuit 70. In addition, conductive wires 64 also connect the batteries 88 through additional diodes 92C and resistors 963 to the integrated circuit 70, which in turn, is connected to the LEDs 50 and the ground 100. The integrated circuit 70 is in connection with the sensor button 62 and switch 72 for actuating functionality of the night-light 20 including sequencing of light beams, and timing means. While this is the preferred electrical diagram, other equivalent diagrams, connects, and functions are contemplated and included as variations herewith.
In conclusion, herein is presented a projection night-light coupled within a plush toy. The invention is illustrated by example in the drawing figures, and throughout the written description. It should be understood that numerous variations are possible, while adhering to the inventive concept. Such variations are contemplated as being a part of the present invention.
