RELATED APPLICATION  
       [0001]    This is a Continuation in Part of U.S. Ser. No. 09/613,198, filed Jul. 10, 2000 in the name of the same applicant of this application, and to which priority is claimed. 
     
    
     
       FIELD OF THE INVENTION  
         [0002]    This invention relates generally to outdoor decoration and, more specifically, to an artificial rock having a design drilled therethrough and having an illumination source therein so that the design may be viewed at night.  
         BACKGROUND OF THE INVENTION  
         [0003]    For the convenience of visitors, for reasons of safety, and for related reasons, it is generally desirable that a building—particularly a residence—have its address prominently marked and visible. In the residential context, this is often achieved by painting the street address on the mail box, by painting the street address on the curb, or by placing wood or tile numbers on the exterior of the house.  
           [0004]    One obvious problem with these methods is that they are generally not readily viewable at night. It is necessary therefore to provide a street address marking that is readily viewed at night. On the other hand, it is also generally desired that the apparatus displaying the street address be aesthetically pleasing. One way of providing an aesthetically pleasing apparatus is to provide one having the appearance of something that might generally be found in the front yard of a home.  
           [0005]    It may also be desired, either together with an address or in place thereof, to provide an aesthetically pleasing design that may be positioned in front of a home (or the like) and that is viewable at night. A wide variety of designs could be possible, including but not limited to American (or other) flags, designs associated with holidays (such as ones of having a Christmas or Halloween theme) or designs associated with particular ethnic or religious groups.  
           [0006]    Thus, a need existed for a device and method for providing a street address display that is both viewable at night but also aesthetically pleasing during daylight hours. A need further existed for a street address display having the appearance of an item that might generally be found in the front yard of a home. A need still further existed for a device and method for providing a design display having these attributes. The present invention satisfies these needs and provides other, related, advantages.  
         SUMMARY OF THE INVENTION  
         [0007]    An object of the present invention is to provide a street address display that is viewable at night.  
           [0008]    A further object of the present invention is to provide a street address display that is viewable at night but also aesthetically pleasing during daylight hours.  
           [0009]    A still further object of the present invention is to provide a street address display that is viewable at night but also aesthetically pleasing during daylight hours and that has the appearance of something that one may expect to find in a typical front yard of a residence.  
           [0010]    A yet further object of the present invention is to provide a design display that is viewable at night, aesthetically pleasing during daylight hours, and that has the appearance of something that one may expect to find in a typical front yard of a residence.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0022]    Referring to FIGS.  1 - 3 , the illuminated artificial rock  10  (the “illuminated rock  10 ”) is shown. The illuminated rock  10  comprises at least the following components: a rock shell  12  having a hollow area  14  therein, a light source  16  located in the hollow area  14 , and a design  17  through the rock shell  12  permitting light transmitted from the light source  16  to pass through the rock shell  12  and be visible to an outside observer. The light source  16  may be a low voltage light, of the type commonly used in landscaping. The light source  16  may, preferably, be colored so as to provide a more aesthetically pleasing design  17 . As discussed below, the rock shell  12  should not only be shaped like a rock, but should also have coloring so as to give it a natural appearance, so as to increase the camouflage effect and to persuade a casual observer during daylight hours that the rock shell  12  is a genuine rock. The rock shell  12  should, preferably, be positioned proximate the front of a home so as to maximize exposure of the design  17 .  
         [0023]    As shown in FIGS. 2 and 3, the illuminated rock  10  further preferably includes a diffusion screen  18  positioned between the light source  16  and the design  17 . The purpose of the diffusion screen  18  is to diffuse the light transmitted from the light source  16  so as to prevent an outside observer looking at the design  17  from seeing the bulb or other element comprising the light source  16 . The diffusion screen  18  may be made from any material—e.g., plastic, glass, etc.—capable of diffusing light, sufficiently able to conceal the element comprising the light source  16 , and yet sufficiently transparent to permit the desired amount of light to illuminate the design  17 . The diffusion screen  18  may optionally be colored so as to alter or improve the visual appearance of the design  17 .  
         [0024]    It should be noted that, depending on the light source  16 , a diffusion screen  18  may not be necessary. For example, where the light source  16  is a low voltage outdoor light(s), a diffusion screen  18  will generally not be needed.  
         [0025]    As shown in FIGS.  1 - 3 , the illuminated rock  10  further preferably comprises a base  20 , over which the rock shell  12  (with the light source  16  positioned therein) may be placed. The base  20  may be made from wood, plastic, metal or virtually any reasonably durable material—though is preferably made from a material having at least some resistance to harm caused by being positioned outdoors on the ground, including harm caused by moisture, insects, etc. The rock shell  12  may simply be placed on top of the base  20 , with the weight of the rock shell  12  maintaining it in position, or it may be secured through openings  22  about the perimeter of the rock shell  12  using screws  24  as shown in FIGS. 2 and 3. Similarly, the light source  16  may be positioned on the base  20  without the benefit of any additional hardware, or may be secured to the base  20  with screws (not shown) through openings  26  in the base of the light source  16 . Still further, the diffusion screen  18  may, optionally, be secured to the base  20  with screws  24  through openings  28  in the base of the diffusion screen—or may be positioned between the light source  16  and design  17  in any one of a variety of other ways.  
         [0026]    For some embodiments, a base  20  will not be desired. For example, if the light source  16  is a low voltage outdoor light of a type that may be appropriately coupled to the ground, it will generally be desired to simply place the rock shell  12  over the light source  16 , without the need for positioning a base  20  below the light source  16 .  
         [0027]    Referring specifically to FIG. 2, preferably the illuminated rock  10  further includes a mechanism for automatically turning the light source  16  on and off at the desired times. One such mechanism is an electric timer  30 , into which the light source  16  may be coupled and which electric timer  30  may then be attached to a power source (not shown) with chord  32 . Other mechanisms for automatically turning the light source  16  on and off would be possible, including the use of a light sensor capable of detecting when the ambient light falls below a certain level—at which point the light source  16  would be activated—and then deactivating the light source  16  when the ambient light falls above a certain level. Such light detectors are well known in the art.  
         [0028]    Referring now to FIGS. 1 and 4, the design  17  in its street number embodiment is discussed. In this regard, the design  17  could be any desired, aesthetically pleasing design—such as a name, one or more letters, one or more numbers, a shape, or any combination thereof—and is not necessarily limited to a street number. However, in the preferred embodiment, the design  17  is a street number. The design  17  in its street number embodiment or otherwise is preferably formed by drilling a series of holes all the way through exterior surface of the rock shell  12 , so as to permit light to pass from the light source  16  through the rock shell  12  where it can be viewed by an outside observer.  
         [0029]    Preferably, this drilling is accomplished by the use of a stencil  34 , preferably having thereon numbers  36  (ranging from  0  to  9 ), each of which is formed by a series of holes as shown in FIG. 4. (While the stencil  34  preferably has a plurality of numbers  36 , it would be possible to have a series of individual stencils  34 , each having only a single number  36 —one each for numbers  0  through  9 .) In this regard, the stencil  34  may be taped to the rock shell  12  in the position desired for placement of the design  17 . The numbers  36  may then be traced onto the rock shell  12  through the stencil  34 , for example using a washable marker. The stencil  34  may then be removed, and the tracing followed by making a series of holes with an electric drill, with any excess marker to be wiped away. Assuming the rock shell  12  is formed of boat resin or like material, a steel bit is preferably used, with a {fraction (5/32)}″ size preferred.  
         [0030]    While the use of a stencil  34  in the manner described above is preferred in the creation of the design  17 , the design  17  may be created in any desired way. For example, a large space could be cut into the rock shell  12 , into which could be inserted and secured a plate or dark plastic piece having a street number or other design drilled thereon.  
         [0031]    The steps of creating the rock shell  12  are preferably as follows:  
         [0032]    1. A mold is first formed, preferably from fiberglass, in the shape of a rock having an open bottom. In forming the mold and in the interest of creating greater realism, real rocks may used, with the fiberglass being formed over the real rocks.  
         [0033]    2. The mold is inverted so that the open bottom is facing upward. The inside surface of the mold is coated with a Johnson paste wax or an aerosol release agent, to allow the finished rock shell  12  to be readily removed from the mold and to provide a sticky base for the colors (discussed below) to adhere.  
         [0034]    3. Coloring, preferably in the form of powdered cement colors, is lightly sprinkled into the mold, taking care to try to cover as much of the surface of the mold as possible. A small brush may be used to assist in the proper distribution of the coloring. Where a brown color is desired, brown, yellow and black powdered cement colors should be used in combination. Where a gray color is desired, gray, yellow and black powdered cement colors should be used in combination.  
         [0035]    4. The material to form the rock shell  12  is created and used to line the mold over the coloring. Preferably, the material used is a composition of boat resin, a catalyst, high fiber powder, and a small amount of liquid white color pigment. This composition should be mixed to a paste-like consistency.  
         [0036]    5. A single coating of the boat resin composition should be applied to the entire interior of the mold over the coloring, using either a paint brush or a sprayer with a large nozzle opening.  
         [0037]    6. Fiberglass matting should be cut into pieces, preferably about eight inches in length, and used to cover the coating of the boat resin composition.  
         [0038]    7. The fiberglass matting layer should be covered with a second coating of the boat resin composition.  
         [0039]    8. The layers of boat resin material should be allowed to set up, preferably for about 30 to 45 minutes. When the material pulls easily away from the mold and slightly snaps back, it is ready to be removed. After removal, the rock shell  12  should be allowed to harden on a flat surface, preferably for approximately four to six hours.  
         [0040]    While these represent the preferred steps for creating the rock shell  12 , essentially any method resulting in an artificial rock shell  12  would be within the spirit or scope of the present invention.  
         [0041]    Referring now to FIGS.  5 - 8 , other embodiments of the illuminated rock  10  are shown, illustrate exemplary (but by no means a full listing) of different categories of designs  17  that may be utilized. For example, referring first to FIG. 5, a design  17   a  is shown consisting of a depiction of an American Flag and the words “USA.” This is exemplary of a design  17  having a patriotic message, and such a message can be expressed using different specific symbols, words, flags, etc. In this embodiment, it may be preferred to utilize either a multi-colored light source  16  or multiple, differently colored diffusion screens  18  to create the effect of a multi-colored design  17 . (It may also be preferred to position the diffusion screens  18  on an interior surface of the rock shell  12 , as opposed to surrounding the light source  16  as shown in FIGS.  2 - 3 .)  
         [0042]    Referring now to FIG. 6, a design  17   b  is shown consisting of a depiction of a Shamrock. This is exemplary of a design  17  conveying an ethnic or religious theme, and, of course, such a message can be expressed using a variety of different specific symbols.  
         [0043]    Referring now to FIG. 7, a design  17   c  is shown consisting of a depiction of a Christmas Tree. Referring to FIG. 8, a design  17   d  is shown consisting of a depiction of a ghost and the word “BOO.” These are meant to be exemplary of a design  17  having a holiday theme and, of course, such a message can be expressed using a variety of different specific symbols.  
         [0044]    It should be noted that the designs  17   a - d  illustrated in FIGS.  5 - 8 —or any variations thereon—may be employed as part of or in addition to a number address as shown in FIG. 1, or in place thereof.  
         [0045]    Of course, designs  17  may be desired that do not fall into one of the “theme” categories exemplified in FIGS.  5 - 8 , and the designs  17  illustrated therein are also intended to generally illustrate that a design  17  can be any desired design capable of being expressed in a rock  12  with a plurality of openings therethrough, permitting such design  17  to be illuminated. In addition to the examples provided, the design  17  could be purely decorative, political, or again could convey any design desired by a particular user and capable of expressed in the manner described herein. Thus, except as specifically claimed, the term “design” is not intended to be limited to any of the specific embodiments disclosed herein.  
         [0046]    While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
