TECHNICAL FIELDThe disclosure herein relates to a personal-use fireplace.
BACKGROUNDFireplaces were originally developed as a dual purpose necessity for early homes and dwellings. Early fireplaces provided both a source of heat during the cooler months of the year and a relatively convenient method for cooking meals year round. As a result of the fireplace's importance in maintaining a livable home, the fireplace became a central place for social interactions and family gatherings. With the evolution of modern methods of central heating and cooking, a fireplace now typically serves only as a secondary heat source and is rarely used for indoor cooking. Although its role as a household necessity has diminished, the fireplace is still a central focal piece in the home for social interactions and often denotes common living spaces. In today's society, a fireplace predominantly functions as a point of visual interest, offering a statement of warmth and providing a cozy ambiance that makes a home more inviting.
Originally, fireplaces almost exclusively relied on wood as a fuel source, and many homes still use wood-burning fireplaces. However, such wood-burning fireplaces produce noxious odors, smoke, and soot, which require the installation of venting systems and the addition of expensive structures such as flumes or chimneys. Even with a sophisticated ventilation system, a wide variety of health risks are associated with residential wood combustion. These risks include carbon monoxide poisoning and an increased incidence of bronchitis, wheezing, coughing, and respiratory infections, with children being the most susceptible. In addition, emissions from wood-burning fireplaces include potential carcinogenic compounds.
Alternative forms of fuel, such as natural gas, allow for the reduction of the noxious combustion byproducts, but require expensive installation of gas lines throughout the home. Gas lines also introduce the potential for a leak if damaged, improperly installed, or unintentionally left on, which can result in the buildup of flammable gas and toxic carbon monoxide within the home. Thus, a more clean-burning fireplace is required.
Fireplaces also typically occupy a large amount of space within a home, effectively reducing the usable square footage of a house or apartment. In light of the rise in real estate prices, installation of a bulky fireplace is often cost prohibitive for many homebuilders and residential complex developers.
As a result of the reduced necessity of fireplaces and their associated expenses, dangers, and potential complications, many houses and apartments now lack this aesthetically pleasing centerpiece. Thus, there is a need for a small, portable, and inexpensive fireplace configured for personal use.
INCORPORATION BY REFERENCEEach patent, patent application, and/or publication mentioned in this specification is herein incorporated by reference in its entirety to the same extent as if each individual patent, patent application, and/or publication was specifically and individually indicated to be incorporated by reference.
Detailed descriptions of one or more preferred embodiments are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in any appropriate manner.
The singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.”
Wherever any of the phrases “for example,” “such as,” “including” and the like are used herein, the phrase “and without limitation” is understood to follow unless explicitly stated otherwise. Similarly “an example,” “exemplary” and the like are understood to be nonlimiting.
The term “substantially” allows for deviations from the descriptor that do not negatively impact the intended purpose. Descriptive terms are understood to be modified by the term “substantially” even if the word “substantially” is not explicitly recited. Therefore, for example, the phrase “wherein the lever extends vertically” means “wherein the lever extends substantially vertically” so long as a precise vertical arrangement is not necessary for the lever to perform its function.
The terms “comprising” and “including” and “having” and “involving” (and similarly “comprises”, “includes,” “has,” and “involves”) and the like are used interchangeably and have the same meaning. Specifically, each of the terms is defined consistent with the common United States patent law definition of “comprising” and is therefore interpreted to be an open term meaning “at least the following,” and is also interpreted not to exclude additional features, limitations, aspects, etc. Thus, for example, “a process involving steps a, b, and c” means that the process includes at least steps a, b and c. Wherever the terms “a” or “an” are used, “one or more” is understood, unless such interpretation is nonsensical in context.
As used herein the term “about” is used to mean approximately, roughly, around, or in the region of. When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 20 percent up or down (higher or lower).
A personal fireplace is described herein. Embodiments of the personal fireplace combine the aesthetically pleasing element of an open flame while removing the necessity of a large and expensive structure. The fireplace described herein further removes the necessity of residential wood combustion and eliminates the associated health risks.
