DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new insect terminating pet dish embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 4, the insect terminating pet dish 10 generally comprises a base assembly including a bowl-shaped base member 11 being adapted to rest upon a ground. The bowl-shaped base member 11 includes a side wall 12, and also includes a beveled top surface 13. The base assembly further includes an insulated mat 16 being disposed along a bottom of the side wall 12 for stabilizing the bowl-shaped base member 11 upon the ground. The bowl-shaped base member 11 is tapered outwardly from a top to a bottom thereof. The beveled top surface 13 has a plurality of holes 15 being disposed therethrough and includes a first hole 14 being disposed through a center of the beveled top surface 13.
A bowl member 17 is spacedly mounted above the bowl-shaped base member 11. The bowl member 17 includes a side wall 18 and a beveled top surface 19 having a hole 20 centrally disposed therethrough with the beveled top surface 19 being adapted to support food and water for a pet. The bowl member 17 is tapered outwardly from a top to a bottom thereof with the side wall 18 of the bowl member 17 spacedly and partially overlapping a top portion of the side wall 12 of the bowl-shaped base member 11.
An insect terminating assembly is conventionally attached to the bowl-shaped base member 11. The insect terminating assembly includes a tubular support member 21 having a bore 22 extending therethrough and being disposed upright upon the beveled top surface 13 of the bowl-shaped base member 11 with the bowl member 17 being mounted upon the tubular support member 21, and also includes a plurality of electrical coils 23 being wound about an exterior of the tubular support member 21, and further includes batteries 24 being disposed below the beveled top surface 13 of the bowl-shaped base member 11 and being connected with wires 25 to the electrical coils 23 for the energizing thereof, and also includes a means for fastening the bowl member 17 and the tubular support member 21 and the bowl-shaped base member 11 together. The means for fastening the bowl member 17 and the tubular support member 21 and the bowl-shaped base member 11 together includes a bolt 26 being extended through the hole 20 of the bowl member 17 and through the bore 22 of the tubular support member 21 and through the first hole 14 of the bowl-shaped base member 11, and also includes a nut 27 being threaded upon a bottom portion of the bolt 26.
Optional variations of the present invention are shown in FIGS. 5 through 8 of the drawings. In FIGS. 4 and 5, the pet food dish apparatus 30 includes a base 32 for resting upon a ground surface, and the base comprises a top wall 34 and a perimeter wall 36 extending generally downwardly from a periphery of the top wall.
The pet food dish apparatus 30 also includes a bowl 38 that is located above the base 32. The bowl 38 comprises an upper wall 40 and a side wall 42 that extends generally downwardly from a periphery of the upper wall. The upper wall 40 may have a substantially concave upper surface for holding pet food, and the side wall 42 may extend generally downwardly and outwardly from the upper wall. Optionally, at least one substantially transparent viewing window 44 may be provided on or formed in the side wall 42 of the bowl to permit viewing through the side wall into a space between the base 32 and the bowl 38. A lower perimeter edge of the side wall 42 may have a diameter that is greater than a diameter of the perimeter wall of the base 32.
The pet food dish apparatus 30 includes a support 46 extending between the base 32 and the bowl 38 to space the bowl from the base. The support 46 may extend upwardly from the base 32 to the bowl 38. The support 46 has an outer surface 48, which may be substantially cylindrical in shape. In one embodiment of the invention, the support 46 may have a height that positions a lower edge of the side wall 42 of the bowl 38 at a lower vertical level than the top wall 34 of the base 32. The support 46 may be removably mounted on the bowl 38, as is shown in the embodiment illustrated in FIGS. 5 and 6, or the support may be removably mounted on the base 32, as is illustrated in the embodiment shown in FIG. 7. The removability of the support from either of the base or the bowl permits access to the space therebetween for cleaning of dead insects from this space, power source replacement if the power source is located in this area, or other types of maintenance.
The pet food dish apparatus 30 also includes an insect terminating assembly 50 for electrically exterminating insects. The insect terminating assembly may include at least a pair of electrically conductive coils 52, 53 that extend about the support 46 in a substantially uniformly spaced relationship to each other. The pair of coils 52, 53 may be substantially helical in shape and may be mounted on and about the support 46. A first coil 52 of the pair of coils may be relatively positively charged and a second coil 53 of the pair of coils may be relatively negatively charged such that an insect simultaneously contacting both the first and second coils closes a circuit that includes the body of the insect, thus shocking and killing the insect at sufficient voltage levels.
The insect terminating assembly may also include a power source 56 for producing a charge on each of the pair of coils. The power source 56 may be electrically connected to each coil of the pair of coils, and a positive terminal of the power source may be connected to the first one of the pair of coils and a negative terminal of the power source may be connected to the second one of the pair of coils. The power source 56 should produce a voltage difference between the first and second coils that is suitable to kill, or at least stun, small insects that will attempt to climb the structure of the invention to reach the pet food. In one embodiment of the invention, a voltage difference of approximately 18 volts has been found to be highly suitable. The power source preferably comprises a battery, although a cord may be provided that connects the pair of coils to a more permanent power source such as an electrical outlet. However, utilizing a cord would limit the available places that the apparatus may be used to those relatively close to an electrical outlet. In one illustrative embodiment of the invention, a pair of nine volt batteries is connected in series to produce a voltage differential of approximately 18 volts.
Significantly, current flows through the circuit of the insect terminating assembly (i.e., the power source 56 and the pair of coils 52, 53) only when the circuit is closed, and the circuit is only closed when the body of an insect contacts both the first and second coils simultaneously. This characteristic of the invention minimizes the draining of power from the power source, and thus increases the intervals over which the power source, or battery, will remain effective.
The power source may be positioned in an interior of the base (see FIG. 6) or in the space between the base and the bowl (see FIG. 7). Significantly, the positioning of the coils and the power source between the base and bowl can provide an extra measure of safety as the possibility of pets licking the coils or the power source is greatly reduced, as well as limiting access of a child to the coils and the power source and reducing the chance of the coils or power source being exposed to moisture in the form of rain, dew, gravy or other sauces associated with the pet food. The positioning of the coils and power source between the base and the bowl also may reduce the possibility that environmental factors such as sunshine (and the resulting heat) and dust may affect the operation of the coils and power source. It should also be noted that the detachability of the bowl from the support, the base, and the insect terminating assembly permits the bowl to be removed and washed with water, such as in a dishwasher, without harming the insect terminating assembly.
Further, while the connection between the support 46 and the bowl 38 illustrated in FIGS. 6 and 7 generally shows a snug or interference fit between the connecting portions of these parts, other forms of connection that are even more secure may be employed. For example, the upper end of the support and the portion of the bowl that is removably engaged to the support may be cooperatively threaded to permit these parts to be removably attached together. As a further example, the upper portion of the support and the mating portion of the bowl may be configured similar to the structures employed to mount a so-called “childproof” cap on a medicine bottle in a manner that is conventional to the art of medicine bottles but otherwise unknown to the pet food dish art.
Another optional variation of the invention, shown in FIG. 8 of the drawings, may be characterized as an insect terminating pet food dish supporting apparatus 60 that includes a base 62 for resting upon a ground surface and a rest member 64 located above the base. The rest member 64 may include an upper wall 66 and a side wall 68 that extends generally downwardly from the upper wall 66. The upper wall 66 of the rest member may have a substantially planar upper surface 67 for resting a pet food dish thereon. The supporting apparatus 60 may also include a support 70 that extends between the base 62 and the rest member 64 to space the rest member from the base. The support apparatus 60 may also include an insect terminating assembly 72 of similar configuration to the insect terminating assembly 50 described above, and thus providing the user with the option to use a specialized or favorite food dish with the insect terminating assembly of the invention.
In use, the user places the insect terminating pet dish apparatus upon a ground or floor surface and connects the power source to the electrical coils to energize the coils such that the electrical coils terminate or stun insects as they contact a pair of the coils as they attempt to walk up the outer surface of the support between the base and the bowl, or the rest member.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction ane operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
