  • the viewing screen 36 is most preferably constructed so that a front side 40 thereof is partially reflective. That is, the screen is configured to reflect at least a portion of the light which is incident upon it. In this way, a reflected image of the fuel bed 28 is seen be user in the screen 36. This has the effect of doubling the perceived depth of the fuel bed 28 and gives the impression that the flame simulation appearing in the screen 36 arises from the middle of the perceived fuel bed (that is, the combination of the actual fuel bed 28 and its reflection).

  • a flame simulating element is provided behind the screen which may typically comprise a web or sheet of material which is provided with apertures.
  • the rear wall 18 is provided on its front surface with a reflector, so that light from the light source is reflected by the reflector through the apertures in the web or sheet onto the viewing screen 36.

  • the sheet is in the form of a fabric or the like, it may be suspended loosely in front of the rear wall 18 and caused to billow in a flow of air, thereby imparting movement to the light incident on the screen 36.
  • the fabric may have reflective properties, for example where the fabric is silk or polyester or the like so that light from the light source is alternatively (or in addition) reflected onto the screen 36 by the billowing fabric.
  • the flame simulating means 26 is provided by one or more flags or strips of material 40 which are loosely suspended behind the screen 36 and in front of the rear wall 18.

  • a blower 42 is arranged in a lower area of the casing 12 to direct a flow of air over the flags 40, so that they are caused to billow.
  • a reflector 44 is arranged behind the flags 40, most preferably on the rear wall 18. The reflector 44 is positioned to reflect light from the light source onto the screen 36 via the flags 40.
  • the reflector ca be any suitable material, but is preferably of polished metal such as brass or a metallic substance or a brassy or silver colour.
  • the reflector 44 may be in the form of a polished metal plate attached to the rear wall 18, or may comprises a metallised plastic, for example.
  • a metallic film or layer may be printed or otherwise attached to the rear wall 18.
  • the reflector may be cut, shaped or treated to resemble the shape of flames.
  • an upper portion thereof may be made matte or darkly coloured to leave a remaining reflective area having the shape of flames.
  • the flags 40 may also include cut-outs or apertures through which light may be transmitted onto the screen 36 after reflection by the reflector 44.
  • the space heating means is preferably a convection heating means and in particular fan heater.
  • the fan heater is arranged to provide a flow of heated air exiting the apparatus, for example through a suitable grille.
  • the fan heater may be arranged at the base of the fire apparatus so that heated air is expelled through a grille at a front portion of the fire apparatus 10 towards the base.
  • the fan heater may be mounted at an upper part of the fire and screened by a decorative canopy extending forwardly from the front of the fire apparatus 10. This arrangement can have disadvantages in effectively extending the front to back dimension of the fire apparatus.
  • the fan heater 50 is mounted at an upper part of the fire apparatus 10 within the cavity 12 defined by the walls 14, 16, 18, 20, 22.
  • the fan heater 50 may, for example, be attached to the top wall 14 and/or the rear wall directly, or indirectly by means such as bracket 18b.

  • the relative positions of the fan heater 50 and the aperture 48 are such that the fan heater is disposed at least predominantly above the top edge 52 of the aperture, so that the fan heater 50 is not normally visible to a user.
  • This arrangement of the fan heater 50, together with the preferred flame and fuel simulating arrangement as described herein, is particularly advantageous in minimising the overall front to back dimension of the simulated fire 10. This is especially important in the case of wall mounted simulated fires.
  • the front panel 46 is preferably substantially planar, but is not necessarily so.
  • the front panel 46 may be made from wood, metal, glass, plastic or other suitable material and may be coloured or otherwise decorated to be appealing to a user.
  • the portions of the front panel 46 other than the aperture are preferably opaque so that the front panel hides at least front portions of the casing 12 from a user's view.
  • the front panel 46 is non-structural, that is, the apparatus is not reliant on the front panel 46 for its structural integrity Rather, the casing 12 is constructed to provide the necessary strength and rigidity of the apparatus 10. By omitting any structural front wall of the casing 12, the construction of the apparatus 10 is simplified, and there is also a significant saving of weight and materials.
  • Mounting means are provided by which the front panel 46 is attached to, and supported by, the casing 12.
  • the walls 14, 16, 20, 22 are provided with a flange 14a, 16a, 20a, 22a extending substantially orthogonally to the respective wall 14, 16, 20, 22.
  • the front panel 46 is mounted so that its rear face 54 is opposed to the respective flanges 14a, 16a, 20a, 22a and preferably lies against said flanges.
  • the mounting means are such that the front panel 46 may be easily removed from the casing, for example to provide access to components of the burning fuel and flame simulating means - such as for replacement of a light source.
  • the front panel may be removed by a user and exchanged for another panel of different appearance.
  • the front panel 46 is mountable and demountable without the use of fastening tools such as screwdrivers, spanners, crimpers and the like and/or without requiring access to the mounting means from the internal cavity 24.
  • mounting means are provided on the rear face 54 of the front panel 46 and are configured to cooperate with suitable formations (which might also be deemed elements of the mounting means) of the casing 12 to mount and retain the front panel 46 on the casing 12.
  • the mounting means comprise upper projecting formations 56 which extend from the rear face 54 of the front panel 46.
  • the projecting formations 56 include a downward facing indent, notch or hook-like portion 58 which receives a suitably placed projecting formation 60 of the casing 12.
  • the front panel thus, in effect, hangs from the formations 60 via the projecting formations 56.
  • the notches 58 ensure that the front panel 46 is securely retained and cannot be inadvertently removed or displaced.
  • the front panel 46 is further provided with lower projecting formations which are received into suitably shaped recesses of the casing, for example slots defined immediately below the moulding 34.
  • the lower projecting formations 62 may conveniently lie in use on top of a lower sub-assembly 64 contained within the lower part of the casing 12, which sub-assembly 64 contains the blower 42 and light source 32.
  • the lower projecting formations 62 (and consequently the front panel 46) are thus supported by the lower sub-assembly 64.
  • the lower projecting formations 62 further assist in retaining the front panel 46 in its location of use.
  • the respective upper and lower formations 56, 62 may, in general, be attached to the front panel 46 by any suitable means. However, it is preferred to attach the respective formations by the simplest possible means using the fewest components. For this reason, it is preferred that the respective formations 56, 62 are adhered to the front panel 46 by a suitable adhesive. In a particularly preferred arrangement the upper projecting formations 56 are each attached to (and more especially are integral with and depend from) a supporting plate 66 which is in turn adhered to the rear face 54 of the front panel 46. The lower projecting formations 62 may be attached in a similar manner.

  • the casing 12 may be supported on suitably sized legs or other suitable supporting means.
  • a user may choose to mount the apparatus 10 on a wall, normally somewhat above floor level.
  • the casing 12 is provided with at least one attachment formation disposed at a rear portion of the casing 12 by means of which the casing 12 may be suspended from a building wall.
