ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to fire enhancement products for campfires and fireplaces, and more specifically it relates to a fire enhancement system for increasing the visual appearance of a fire with a simple to utilize structure.
Fires are commonly utilized by individuals to provide warmth and sometimes merely for aesthetic reasons. Wood fires typically display white, red and orange colors within their flames. It is desirable to increase the visual appearance of these fires to provide an increased aesthetic appearance.
2. Description of the Prior Art
Fire enhancement devices have been in use for years. Typically, an “artificial log” is comprised of wood material along with various chemicals to decrease the amount of time to ignite a fire. Some fire enhancement products add a scent to the fire to make the scent of the fire pleasing to individuals adjacent the fire.
Examples of patented fire enhancement devices include U.S. Pat. No. 3,370,932 to Kelly et al.; U.S. Pat. No. 2,398,571 to Young; U.S. Pat. No. 4,309,189 to Oberhardt; U.S. Pat. No. 4,997,457 to Mitsusawa et al.; U.S. Pat. No. 4,062,655 to Brockbank; U.S. Pat. No. 2,373,512 to Starner which are all illustrative of such prior art. The disclosures and content of these patents are hereby incorporated by reference regarding the present patent application.
While these devices may be suitable for the particular purpose to which they address, they are not as suitable for increasing the visual appearance of a fire with a simple to utilize structure. Conventional products on the market do not increase the visual appearance of the fire. Patented inventions do not provide an easy self-contained structure to utilize to increase the visual appearance of the fire.
In these respects, the fire enhancement system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of increasing the visual appearance of a fire with a simple to utilize structure.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of fire enhancement devices now present in the prior art, the present invention provides a new fire enhancement system construction wherein the same can be utilized for increasing the visual appearance of a fire with a simple to utilize structure.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new fire enhancement system that has many of the advantages of the fire enhancement devices mentioned heretofore and many novel features that result in a new fire enhancement system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art fire enhancement devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises an outer tube defining an interior cavity, and a fuel member positioned within the interior cavity of the outer tube. The outer tube is preferably comprised of copper tubing or similar composition of copper with the fuel member comprised of a plastic material thereby forming a chemical reaction when heated thereby displaying a pleasing variety of colors within a fire. The outer tube may include a first cap and a second cap for preventing the fuel member from exiting the outer tube.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
A primary object of the present invention is to provide a fire enhancement system that will overcome the shortcomings of the prior art devices.
A second object is to provide a fire enhancement system for increasing the visual appearance of a fire with a simple to utilize structure.
Another object is to provide a fire enhancement system that dramatically increases the total number of colors displayed within a fire.
An additional object is to provide a fire enhancement system that increases the blue and green colors of the fire.
A further object is to provide a fire enhancement system that is self-contained in a convenient structure.
Another object is to provide a fire enhancement system that can be easily manufactured.
A further object is to provide a fire enhancement system that can be utilized upon various types of fires including campfires and fireplaces.
Another object is to provide a fire enhancement system that continuously displays various colors for an extended period of time.
Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages are within the scope of the present invention.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
