Description
REMOVABLE PANEL AND ROTATOR FRAME FOR :LIGHT SOURCE IN
ELECTRIC FIREPLACES
SPECIFICATION
BACKGROUND OF THE INVENTION
This invention relates to flame simulators used as aesthetic and heat substitutes for actual flames in a fireplace.
PRIOR TECHNOLOGY
There exist flame simulators in which light from a light source is projected up through a rotating cylinder, onto a reflective screen and through a coloured filter screen. There also exist flame simulators in which light from a light source is reflected from a metallic strip onto a rotating set of coloured metallic strips and then projected through a flame effect element before being finally reflected from a mirror to an observer.
PURPOSE OF THE INVENTION
l The purpose of the system is to provide heat as well as interesting and pleasing visible flame patterns within an electric fireplace without having a complicated and expensive arrangement of parts, without having an actual fire in the fireplace, and without it being a difficult problem to change the bulb or other light source in the electric fireplace.
SUMMARY ~F THE INVENTION
The invention provides a maintainable electric fireplace flame simulator having an excellent means of simulating flames, namely a rotator with light-emitting variegated slots for flame simulation in electric fireplaces, comprising a light source mounted within a rotatable hollow cylinder, the cylinder having a multiplicity of slots in a cylinder that disperse heat and project light from the light source to simulate flames when the cylinder is rotated about the light source. Because the rotatable hollow cylinder is contained within a fireplace or stove box, and behind a light diffuser and simulated fuel bed, all of which confine ready access to the rotatable hollow cylinder, it is important to have an easy means of opening the cylinder within the box once accessed when necessary to change the light bulbs of the light source.
The light source is non-rotatably mounted within the rotatable hollow cylinder, the cylinder having slots shaped to simulate different kinds of flames during rotation of the cylinder about the light source.

The invention provides a maintainable electric fireplace flame simulator having an excellent means of simulating flames, namely a rotator with light-emitting variegated slots for flame simulation in electric fireplaces, comprising a light source mounted within a rotatable hollow cylinder, the cylinder having a multiplicity of slots in a cylinder that disperse heat and project light from the light source to simulate flames when the cylinder is rotated about the light source. Because the rotatable hollow cylinder is contained within a fireplace or stove box, and behind a light diffuser and simulated fuel bed, all of which confine ready access to the rotatable hollow cylinder, it is important to have an easy means of opening the cylinder within the box once accessed when necessary to change the light bulbs of the light source.
The light source is non-rotatably mounted within the rotatable hollow cylinder, the cylinder having slots shaped to simulate different kinds of flames during rotation of the cylinder about the light source.
The light source is suspended on a fixed, light source rod within the rotatable hollow cylinder such that its rotation does not rotate the light source. The rotatable hollow cylinder is rotatably mounted at its rims on either end, and has end plates, one of which has a center hole through which the light source rod is mounted. The light source could be a plurality of incandescent bulbs, light emitting diodes, or a long florescent tube. The bulb receptacles are rotatably mounted within the rotatable cylinder that the rotatable hollow cylinder can rotate around them within its frame without the bulb receptacles themselves rotating with respect to the frame. The flame simulator works by having a motor and motor drive mechanism engagably mounted to the rotatable hollow cylinder mounted on the frame, with a rotator collar for the light to enable the rotatable hollow cylinder to rotate under power, without having the light source xod rotate.
The light fluctuating through the slots creates a flickering flame effect.
Access to the light source through the rotatable hollow cylinder is ingeniously provided by having the cylinder comprised of two flexible half drums, and having a frame for the rotatable hollow cylinder comprised of a pair of half drum flange retaining rods between rotator end plates. The invention thus provides an electric fireplace flame simulator having an excellent means of simulating flames, namely a maintainable rotator with light-emitting slots comprising a light source mounted within a rotatable hollow cylinder, the cylinder being made of two flexible half drum panels mounted on an opposing pair of half drum panel flange retaining rods between rotator end plates. A

Each flexible half drum panel can be squeezed and then engaged or disengaged from the flange retaining rods in order to provide access for changing the light source.
When access to the interior of the rotatable hollow cylinder is desired, for example, for periodic replacement of burnt out bulbs, one of the halves oi'the cylinder can be squeezed together with a user's hand, which withdraws the half drum's long flanges from the opposing frame rods, allowing the entire drum half to be removed. The old bulb can then be taken out, a new bulb can then be put in, and the half drum replaced by squeezing it, inserting it in position within the frame rods, and releasing the half drum such that its long flanges axe held within the indented retaining rods.

Figure 7 is a perspective view of the rotatable hollow cylinder of the present invention, formed by two half drums each having two, opposing long flanges DETAILED DESCRIPTION
lZeferring to Figures l and 2, the cylinder frame 20 for the rotator holds a motor 121 at one end that rotatably drives the hollow cylinder 1 formed from the fron half drum 122 and the back half drum 123. The motor drive rod 124 is inserted through frame end bracket I25 and engages with the cylinder frame motor end plate 12.6. The cylinder frame motor end plate 126 is connected to the cylinder light rod end plate 127 by tap flange retaining rod 128, bottom flange retaining rod 129, and the pair of half drum backing rods I30 and 13I . The rotator is assembled by squeezing the front and back half drums such that the top flanges 140 and I41 on front and back half drums 122 and 123 respectively fit within the bottom inset (143 in Figure 3) of top flange retaining rod 128.
Likewise the bottom flanges 144 and 145 on front and back half drums 122 and respectively can be squeezed and then released to fit within the top inset 146 of the bottom flange retaining rod 1290 The half drums are made of a thin resilient sheet material, such as thin sheet metal, that can be rolled into a squeezable half drum form, and folded along its long edges to form the long top and bottom flanges.
Still referring to Figures l and 2, the light source rod 150 is inserted through light source end bracket 151 along the middle of the cylinder frame formed by the rods 127, 128, 129, and 130 and the end plates 126 and 127. Lights 160 and 161 are mounted in sockets 162 and 163 respectively, which are attached to the light source rod I 50 by brackets 164 and 165 respectively. The light source rod 150 is secured in the frame 20 by the light rod collar 152. Quiet and smooth rotation is assisted by the rotator bushing 163 inserted between the cylinder light rod end plate 127 and the bushing collar 154. In Figure 2 the cutaway line is indicated as 170.
Referring to Figure 3, the frame 20 for the rotatable hollow cylinder 1 can be mounted within an electric fireplace 2 as shown in Figure 2 3 such that the light emitted from the light bulb 12 through the rotating slots 93, 94, 95, and 96 of the rotatable hollow cylinder 1 is projected through a grill screen 101, a diffuser screen 102 and a clear screen 103 into a simulated fire fuel source 22 such as an artistically arranged pile of charcoal and logs.
The diffuser screen can be made of molded plastic that is translucent but not transparent, in order to soften and diffuse the Light that is projected through the perforations, producing a variable glow that enhances the simulation of flames. The electric fireplace comprises such other stock components as a heater 30. A second string 32 of light bulbs can be used in combination with another light diffuser panel 33 to provide additional heat and light to that of the flame simulator light source within the rotatable hollow cylinder.
In Figure 4, the cutaway portion shows four different layers, each progressively deeper within the simulated fireplace. Starting at the right portion of the cutaway (between cutaway lines shown as 181 and 182), the clear screen 103 is behind the simulated fire fuel source 22.. Behind it (the next portion of the cutaway to the left, between cutaway lines 182 and 183) is the diffuser screen 102, behind which is the grill screen l0I (the middle portion of the cutaway, between cutaway lines 183 and 184). Lastly, the left portion of the cutaway between cutaway lines 184 and 18~ shows the rotatable hollow cylinder l, with its smaller, slightly S-shaped slots as at 2, its larger, slightly S-shaped slots as at 3, and its teardrop slots as at 4 and (in hidden vie~~ outline) at 5, the teardrop-shaped slots being in a row that is staggered with respect to the S-shaped slots. The staggering creates a waved flickering effect as between the larger flame simulated via the teardrop shaped central slots and the S-shaped slots in the side portions of the rotatable hollow cylinder 1.
Referring to Figure 5, various other frame components 40 through 44 and electrical components such as on-off switch 51, thermostat 52, overheat control circuit 53 allow the fireplace to be assembled into a unit that is functional, aesthetically engaging, heat-producing, controllable, and safe.
Referring to Figure 6, the rotatable hollow cylinder's front half drum has a proliferation of slots as at 93 and 94 stamped out, through which light can be projected. In Figure 7, the front half drum 122 has been joined with a like half=drum 123 to form the rotatable hollow cylinder with the edge flanges 140 and 144 abutting and the opposite edge flanges 144 and 145 abutting.
The light source can provide infra-red radiation as well as visible light.
This maintainable light-emitting rotator arrangement eliminates reflectors, coloured filters, and flicker elements of other pre-existing flame simulators, while enabling light source bulb changes and maintenance. The rotator also renders it unnecessary to have a separate bulb-cooling blower and as the light emitting rotor itself disperses the heal: from the light source by circulating air around the light source and through the slots.
The central area of the flame simulator can be made brighter by having a greater concentration of perforations in the rotatable hollow cylinder in its central portion, or by having a brighter bulb or a greater concentration of bulbs extend into the central area of the rotatable hollow cylinder, or by a combination of both such arrangements.
Any number of bulbs mounted along the light source rod could readily be accessed by the presently disclosed removable panel and rotator frame For light source in electric fireplaces The within-described invention may be embodied in other specific forms and with additional options and accessories without departing from the spirit or essential characteristics thereof. The presently disclosed embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the irmention being indicated by the appended claims rather than by the foregoing descripti~~n, and all changes which come within the meaning and range of equivalence of the claims are therefore intended to be embraced therein.
