The front and rear oblate sections 12 and 13 are connected by a pinched or tapered mid section 14. The rear oblate section 13 has a closed end 15 while the front oblate section has an open end 16. The casing or housing 11 formed by the oblate sections 12 and 13 and mid-section 14 has a top 17, a bottom 18 and opposed sides 19 and 20. As used throughout the application and in the appended claims, the term “erogeric configuration” is intended to mean and should be understood as meaning the description thereof set forth hereinabove and as illustrated in FIGS. 1, 4 and 6.
The opposed sides 19 and 20 of the casing or housing 11 can be provided with a commercially available glow-in-the-dark soft plastic material 22 to absorb any shock should the child's nightlight should be dropped or fall onto a hard surface.
Removable covers 23 and 24 can be provided on either the top 17 or the bottom 18 of the casing or housing 11 (here shown on the top 17 of the casing or housing 11). The removable covers 23 and 24 provide access to the power source compartment and projection assemblage within the casing or housing 11 and function similar to slide/snap fit covers used to access battery compartments of commercially available portable telephones and cameras.
In FIGS. 2 and 3 there is illustrated the open 16 end of the casing or housing 11 when the illumination means are unlit (FIG. 2) and when the illumination means are lit (FIG. 3) showing the lit light bulbs 46 as described in more detail hereinbelow.
FIGS. 2 and 3 also identify a conventional, commercially available on-off button switch 21 seared on the bottom 18 of the casing 11. Button switch 21 serves to activate and deactivate (turn on and off) the primary electric powe source; i.e., the batteries (FIG. 4), that supply electric power to the nightlight.
Button switch 21 can be located anywhere along the logitudinal axis of bottom 18, but is preferably positioned at an area where the nightlight would be in contact with the wrist area of a child when the nightlight is worn on the wrist of a child as described more fully hereinbelow. In this position, a child can turn the button switch on and off by merely exerting downward pressure with its forearm onto a suitable surface.
FIG. 4 illustrates the internal components of the child's nightlight of the invention comprising a power package to provide an electrical power source, generally indicated by reference numeral 30, a projection assemblage, generally indicated by reference numeral 40 and a means to rotate the projection package 30 is used to provide an electrical power source that can be provided from any commercially available selection of dry cell batteries such as AAA batteries 31, 32 and 33 that are positioned to contact conventional conducting plates or strips 34. Using conventional means such as coil springs, the positive (anode) ends of the batteries 31, 32 and 33 can be urged to contact the conducting plates or strips 34.
FIG. 4A illustrates one means for providing electrical power to various components within the nightlight of the invention. For clarity, the casing 11, closed end 15 and open end 16 of the nightlight are shown in phantom. For purposes of orientation, the power package; i.e., batteries, is indicated at 30 and the projection assemblage is indicated at 40.
The inner end of the power package 30 is provided with an additional conducting plate 34A. The rearward ends of electrical circuit power leads 35A and 35B are electrically secured to conducting plate 34A to receive power from the batteries in the power package 30. Lead 35A conducts the positive current and lead 35B conducts the negative current. These leads 35A and 35B are disposed to extend longitudinally from the connecting plate 34A forward to and through the projection assemblage 40 to complete circuit within the nightlight casing 11. This electrical circuit supplies electrical power to various components of the nightlight such as the motor 51 (FIG. 4) the various lights (FIG. 5) and gear assemblage (FIG. 5A).
As a safety feature to protect a child using the nightlight and to extend the useful life of the batteries supplying the electrical power, an automatic “on-off” timing device, shown in phantom at 36, is preferably included in the nightlight. The timing device 36 can be electrically connected to the electrical circuit by means of electrical leads 36A, 36B electrically secured to conductors 35A and 35B.
Commercially available automatic on-off” timing devices of the type that are typically used in many children's toys are suitable for use in the nightlight of the invention. These commercial timing devices have various, pre-set time durations that act to cut off the electrical power at the end of the time period. One can select a timing device having the time duration desired.
For use in the nightlight of the invention, those timing devices having pre-set times of from about 5 minutes to about 20 minutes would be adequate.
Should the timing device activate itself and turn off the electrical power in the nightlight, the nightlight can be restarted by a child by simply engaging the on-off button 21 (FIG. 1) whereupon the timing device will automatically restart its timing period.
FIGS. 4 and 5 illustrate details of the projection assemblage 40 of the night light of the invention. This assemblage includes a transparent, hollow cover 41, shown here in the geometric form of a bullet, a light bulb housing 42 nested within the transparent cover 41 and a hollow, cylindrical stem 43 extending rearwardly from the center of the light bulb housing. Transparent cover is removably secured to the inner end of the light bulb housing by conventional means such as a snap-fit engagement, mating screw threads, and the like.
In the embodiment illustrated in FIG. 5A, the rotation means 50 used to provide rotation to the projection assemblage 40 comprises a motor 51 and a plurality of intermeshing sprockets such as rear sprocket 52, intermediate sprocket 53 and front sprocket 54. A spindle 55 extending outwardly from the motor 51 and secured to the center hub of rear sprocket 52 causes the rear sprocket 52 to rotate which, in turn, causes the intermediate sprocket 53 and front sprocket 54 to rotate
As more clearly shown in FIG. 5A, the front sprocket 54 has an inwardly extending spindle 56 with a worm gear 57 at its inner end that is positioned to engage cogs 48 provided on the outer surface of the inner end of the hollow cylindrical stem or shaft 43. Thus, when power is supplied from the power source 30, the motor 51 serves to rotate the sprockets 52, 53 and 54 as well as the spindle 56 bearing worm gear 57 to rotate the projection assemblage 40 at the open end 16 of the nightlight 10.
Transparent, hollow cover 41 has a plurality of image decals adhered in a randomly spaced manner about its outer surface such as a star, a crescent moon and a come all as illustrated in FIG. 6.
As can be seen in FIG. 5, light bulb housing 42 is in the form of a cylinder or drum and has a plurality of spaced apart light bulb receptacles 45 formed in its outer surface to receive miniature light bulbs 46 therein. The miniature light bulbs that can be used are commercially available and are similar to the types used to light up Christmas trees or in cell phones, and the like but having a higher wattage output of from about 6 to about 10. These miniature light bulbs provide a secondary source of illumination for the nightlight of the invention
The primary source of illumination for the nightlight of the invention is provided by a MAG light 47 (FIG. 5). MAG light 47, after being connected to a conventional receptacle 49, is positioned to nest within the hollow stem or shaft 43 as indicated in FIG. 5. MAG light 47 is a commercially available light of the type that has a narrow light band capable of creating a prism effect enabling the images contained on the outer surface of the transparent, hollow cover 41 to be displayed in a 3-dimensional configuration.
The MAG light bulb and the miniature light bulbs can be all white, all of the same monochromatic color such as red, orange, yellow, green, blue, indigo and the like.
The motor 51 that can be used is one that is commercially available and is of the type typically employed in remote control devices to steer and manipulate powered toy cars and airplanes.
FIG. 6 illustrates the nightlight 10 secured to the lower arm 60 of a child adjacent its wrist area 62 by means of an elastic band or Velcro straps 63. As illustrated, a variety of images can be projected by the projection means onto a ceiling or a wall area in various forms such as fish, balls, a car, a plane, a sail boat, and the like.
Except for the conducting metals, the motor and the power source, the materials used to fabricate the nightlight of the invention can be provided from any suitable source such as metal, wood, plastics, and the like as well as combinations thereof. Preferably, durable and lightweight plastic materials are preferred such as high density polyethylenes, polypropylenes, polysulfones, polystyrenes, and the like. The transparent, hollow image carrying member 41 should preferably be provided from non-shattering materials such as celluloid or Plexiglas.
Although the invention has been described in some detail and with particularity, it will be appreciated by those skilled in the art that various changes and modifications can be made therein without departing from the scope and spirit of the invention.
