Abstract

A unit to produce simulated burning and heat includes a lower enclosure that may be conveniently placed on a hearth of a fireplace, for example. Within this enclosure is a light source and a reflection wheel located over a reflective plate. The reflection wheel comprises a series of reflective strips which are positioned along a length of the wheel and radially spaced thereabout. Above the wheel in a top panel of the enclosure is an opening covered by an amber-red colored lens piece. The unit further includes a grate carried by the enclosure and positioned to a rear of the enclosure top panel opening. On the grate is a fuel cell for cans of gel alcohol. In front of the fuel cell is a set of decorative logs which hide the fuel cell from view. During use alcohol in the cans may be ignited to produce heat. Since the products of combustion from burning alcohol are nontoxic, the fireplace may be vented or nonvented. Additionally, a geared motor connected to the reflection wheel and the light source are energized. Light from this source strikes the reflective plate and the rotating reflective strips of the wheel to produce a series of reflections. These many reflections then combine to form light patterns of varying intensity that reflect upward through the lens piece to illuminate ash-like aggregate covering the lens piece, the logs, and interior walls of the fireplace. The light patterns produce an illusion of the logs and hot ash burning with a fiery glow.

Claims

1. A unit to create an illusion of burning of natural wood logs in a fireplace, said unit comprising:

an enclosure defined in part by a bottom and a top panel spaced thereabove,

a reflective plate fitting on said enclosure bottom,

a reflection wheel including an elongated shaft carried by said enclosure and spaced between said enclosure bottom and said top panel to align with said reflective plate, said wheel having numerous, individual reflective strips attached to and positioned along said shaft and radially spaced thereabout in a spiral-like pattern,

rotating means operatively connected to said wheel to slowly rotate said wheel,

an elongated light source carried by said enclosure and positioned to proximately align with said reflection wheel and form an unobstructed space between said reflective plate, said light source and said wheel for direct passage of light therebetween,

lens means positioned over an opening in said enclosure top panel with said opening aligning with said reflective plate and said wheel, said lens means prepared to transmit light from said light source therethrough having an amber-red like color, and

fireplace paraphernalia carried on said enclosure top panel, said paraphernalia including a set of spaced apart log portions positioned over said lens means with said log portions having enhanced reflective lower edges,

wherein during use of said unit light from said source, light reflection from said reflective plate and light selectively reflecting from said slowly rotating reflective strips of said wheel may mix to create patterns of light that illuminate upward to pass through said lens means and reflect from said bottom edges of said log portions to create said illusion of burning of said log portions.

2. A fireplace unit to produce an illusion of burning logs on a hearth of a fireplace, said unit comprising:

an enclosure prepared to be carried on said hearth, said enclosure defined by a bottom, spaced apart sidewalls, a connecting front and rear wall, and a top panel with an opening formed therein,

an elongated light bulb carried by said enclosure between said bottom and said top panel,

a reflection wheel including a shaft having ends carried respectively by spaced apart angle brackets attached to said enclosure bottom, and a series of reflective strips carried by said shaft and extending continuously between said shaft ends with said strips projecting radially outward from said shaft and spaced radially apart in a spiral-like pattern,

a geared motor attached to one angle bracket and operatively connected to said adjacent shaft end with said motor and said bulb prepared to be operatively joined to a source of electrical power,

a reflective plate carried on said enclosure bottom, said plate positioned under said reflection wheel,

an amber-red lens attached to said top panel to cover said opening in said top panel,

a grate having pairs of legs carried on said enclosure top panel and positioned respectively on each side of said top panel opening, said grate further defined by a series of spaced apart bars formed with upturned ends,

a set of artificial log portions carried longitudinally by said grate, a first log portion of said set positioned immediately inward from said bar upturned ends and a second log portion of said set spaced above and to a rear of said first log portion, each said log portion formed with a reflective bottom edge visible from in front of said fireplace,

said reflection wheel shaft formed by a pair of elongated wires, and

said reflective strips formed from a sheet of flexible material having light reflective characteristics, said sheet formed with sets of spaced apart slits with one each of said slit sets extending inward from respective longitudinal edges of said sheet and terminating at a narrow area in a middle of said sheet, and one said set of slits being longitudinally offset from said other set of slits,

wherein one each of said shaft wires is placed on respective sides of said sheet narrow area and then said wires are twisted to place said reflective strips in said spiral-like pattern and with a slight degree of pitch; and

, during operation of said unit, light from said bulb strikes said reflective plate and said reflective strips of said reflection wheel as said wheel is slowly rotated by said motor, said striking light reflects therefrom and intermixes to create upward illuminating light patterns having varying intensities, said light patterns then passing through said lens to be transformed from a white to a varying amber-red color and striking said bottom edges of said log portions and reflecting outward to form said illusional view of said log portions burning.

3. A fireplace unit as defined by claim 2 and further characterized by said unit including a fuel cell carried on said grate, said fuel cell comprising:

a fire box prepared to hold containers of a gel alcohol fuel with said fire box defined in part by rearward extending sidewalls having top edges forming a guide for a lid selectively slidable to a position to cover or uncover said containers, and end brackets attached to said fire box sidewalls and extending forward therefrom to hold said second log portion.

4. A fireplace unit as defined by claim 2 and further characterized by:

said elongated light bulb positioned below said reflection wheel shaft with said shaft located over a front portion of said reflective plate, and said plate in substantial vertical alignment with said enclosure top panel opening.

5. A fireplace unit as defined by claim 4 and further characterized by,

said top panel opening being larger in area than said reflective plate.

6. A fireplace unit defined by claim 2 and further characterized by said unit including,

an ash-like material dispensed on said enclosure top panel and said lens,

wherein said light patterns reflect from said material to create an illusion of said material forming glowing coals from said burning log portions.

7. A fireplace unit as defined by claim 2 and further characterized by,

said hearth forming part of a nonvented fireplace cabinet.

8. A unit for fireplace burning simulation including emitter means to create a visual burning illusion, said emitter means comprising:

an elongated light source carried by said emitter means,

a reflective surface carried by said emitter means and positioned below said light source,

a rotatable wheel having a series of individual, spaced apart reflective strips formed into a spiral-like array about and along a length of said wheel, said wheel carried by said emitter means and positioned to proximately align with said light source and above said reflective surface to form an unobstructed space between said light source, said wheel and said reflective surface, and

lens means carried by said emitter means and positioned above said wheel to allow an upward illumination having an amber-red color,

wherein light from said source and light reflecting from said reflective surface selectively passing through said wheel, selectively reflecting from said wheel reflective strips, and selectively obstructed by said wheel strips may mix and form said upward illumination defining dynamic patterns of flickering light which may strike and reflect from fireplace paraphernalia positioned above said lens means to create said visual burning illusion.
