Abstract

The invention provides panels for use as fire surrounds. In order to reduce the weight of the panels a high density material 5 such as stone, marble, etc is secured to a low density layer 4 formed of honeycomb aluminium, fibreglass or plastic for example. Methods of manufacture are also described wherein the low density material is secured to the high density material which is subsequently cut. The panels may also find use for picture frames for example.

Description

COMPONENTS FOR FIRES
The present invention relates to a component for a fire, for example a surround and particularly, although not exclusively, to a surround for a fire, as well as a back panel, hearth and the like.
Gas fires are well known for use in the home. One particular type of gas fire which is of increasing popularity is the flueless, flame effect gas fire.
S * S S * S. S
These fires are attractive because they do not have a flue and so can be relatively shallow. Examples of such fires are sold under the trademarks Burley Elan 4111, Plasma Platinum and others. S... * S 5S5S S...
Because of their size, and the fact that a chimney is not required, it is possible to install *,. : these fires in an elevated condition, for example mounted to a wall.
Modern internal walls used in many houses are fabricated from plasterboard which is skimmed with plaster Clearly the weight-bearing characteristics of such walls is less than that of a cavity or solid wall.
It is usual to provide a surround around a gas fire for the purposes of aesthetics. In many cases it is desirous to have a stone surround. Conventional stone surrounds are heavy due to the density of stone.
It will be appreciated that there is a limit to the weight which can be borne by a dry lined or timber framed construction wall Alternatively, a large number of fixings and/or reinforcements can be used to spread the load The price of failure of a fixing when a fire is installed, for example, in an elevated position, may be catastrophic both in terms of damage to property and personal injury.
Moreover, heavy surrounds are cumbersome and transporting and installing such heavy surrounds may be problematic For example, installation may require large labour costs, especially when installing at an elevated location.
It is an object of the present invention to provide a solution to, or at least partially mitigate, one or more of the above-identified problems Additionally or alternatively it is an object of the invention to provide a new surround which is attractive and/or which satisfies contemporary design issues and/or which has a flexibility of use. * * * * * ** **
Accordingly, a first aspect of the invention provides a component for a fire, the *. S...
component comprising a body fabricated from a light weight material to which is.. : secured a fascia material.
Preferably the fascia material is a natural material which may be selected from ceramics, stone, minerals or metal The stone is preferably selected from limestone, marble, granite, slate and so on.
Typically, the fascia may be 2 - 35 mm thick, say 2 to 20 mm and preferably 5mm thick Preferably the light weight material is porous In this specification the term light weight' refers to a material having a density less than that of the fascia material For example, if the fascia material say, stone, (e.g. granite having a density of 2600 kg m), the light weight material will have a lower density, preferably over 50% less than that of the fascia, (e g. a density of less than 1300kg m3), and most preferably significantly less than 50% of the density of the fascia material The porous material may comprise an aluminium honeycomb material, preferably provided with an array of regular or irregular cells which may be interconnected to provide fluid communication therebetween Preferably a core comprising cells has a facing bonded to a surface thereof. The core may be a flat structure with a facing bonded or otherwise secured to one or both major surfacestoforma panel Preferably the fascia material is bonded to the light weight, e.g porous material, for * * example, bonded to a facing of a core of a porous material. S... * * S... S...
In all cases, it is preferred that the component, especially when used as a surround for..
a fire, will have a total weight of less than 40 kg, preferable less than 30 kg and preferably less than 25 kg when provided as an article in the form of a picture frame having external dimensions 1002 x 642 mm with a depth of 76 mm and an aperture of 538 x 286 mm. The low weight will ensure that the article can be elevated, preferably with ease, by two people.
Preferably, the light weight material, e.g. the aluminium honeycomb panel, will be from 8 to 30 mm thick, preferably 10 to 20 mm thick and most preferably 11 to 18, say 15 mm thick In order that the invention may be more fully understood, it will now be described by way of example only and with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a surround according to the invention, Figure 2 is a perspective view of the rear of a surround according to the invention.
Figure 3A is an elevation of the surround of Figure 2; Figure 3B is a view along line A-A of Figure 3A; and Figure 4 is an exploded view of a section through a surround according to the invention Turning to Figure 1 there is shown a flueless gas effect fire FF which is provided with a surround 1 made in accordance with the invention. As can be seen, the fire FF is mounted on a wall W in an elevated position. The wall W may be, for example, a solid cavity, dry lined or timber frame construction wall. S...
S S...
Turning to Figures 2, 3A and 3B the surround 1 provides a frame 2 having a front 21.. : and sides 22 and defining an aperture 3 to accept, for example, a fire FF. The surround includes a body 4 of an aluminium honeycomb material to which is bonded, on all exposed surfaces which are visible when installed, a stone fascia 5. Support blocks 6 are provided to improve the rigidity of the frame 2.
Figure 4 shows an exploded and exaggerated view of a section through a surround 1 wherein the fascia 5 and honeycomb structure 4 are shown The honeycomb structure 4 comprises a panel 40 formed of a pair of aluminium facings 41 bonded to core 42 comprising a plurality of cells 43 It will be appreciated that in the specific example shown the principal axis of the cells 43 is orthogonal to the principal axis of each facing 41 The panel 40 will typically be 15 mm thick although other thicknesses may be used For ease of packing the cells 43 will typically have a hexagonal cross section The physical data of a panel 40 fabricated from 3003 commercial grade aluminium is as follows Cell Size!

To form a panel 40 a two-part epoxy resin is used to bond the facings 41 to the core..
42. Typically the adhesive is pre-mixed and sprayed onto a surface of the facing 41 using a computer controlled spray booth. The facing 41 is brought into intimate contact with the core 42 and the adhesive wicks onto the walls of the cells 43 The panel 40 is then passed to a roller table to press to effect compression of the panel 40 The rollers or press may be heated to aid in the cure of the adhesive The panel 40 may be formed with wiring, tubing or ancillary fixings to provide, for example, concealed connection points, if required The panel 40 may then be cut to size to provide the front 21 and sides 22 from which the frame 2 can be constructed The sides 22 will typically be adhered to the front 21 using a similar two part epoxy adhesive At this point, the support blocks 6 are joined to the frame to help rigidify the structure.
The fascia material 5 is then bonded to the facing 41 to cover all surfaces which are exposed in use. The adhesive is selected so that it will not degrade at the temperatures experienced during use. * S * 1 I. *
As an alternative, a panel 40, formed as above, is bonded to either side of a sheet of * fascia material, for example 10-12 mm thick stone. The stone can then be cut (e.g. sawed) to provide two panels each comprising a honeycomb panel 40 and a stone fascia 5, e.g. the stone having a thickness of 5 to 6 mm. *. **** S...
liz. S* IS * Whilst this does introduce a further cutting stage it also reduces the likelihood of damage occurring to the relatively thin stone material before it is adhered to the panel 40.
In either or both cases stone may then be polished or honed as appropriate.
A typical surround, as shown in Figures 3A and 3B may be, say 1002 x 642 mm with a depth of 76 mm and an aperture 3 of 538 x 286 mm. Other sizes may be used.
For a surround 1 having a 15 mm thick body 4 of 3003 aluminium honeycomb panels and a form as shown in Figure 3A and 3B, it has been found that when a 5mm thick fascia of granite is used a surround 1 has a total weight of 19.4kg m, compared to 60kg m2 for an equivalent surround fabricated from granite Clearly, this represents a significant weight saving which will reduce shipping and installation costs, it may reduce material costs and the amount of natural materials which are used, It will also reduce the likelihood of damage to the surround 1 during transit.
Moreover because of the reduction in weight, the surround 1 can be installed using fewer or lower duty fixings, fewer man hours and the risk of a catastrophic failure is correspondingly reduced.
Other honeycomb materials which may be used include fibreglass, Keviar, reinforced or unreinforced plastics and so on. *...
I.) .. . The porous material need not be aluminium and/or a honeycomb structure For example, porous ceramics can be used It is known that porous ceramics can have very low theoretical densities whilst maintaining structural strength.
A porous ceramic material may be provided as a monolithic block or as several components joined together.
Other low mass weight saving materials may be used, for example, pumice. In most cases it will be preferably that the volume of free-space (e.g. air) in the body is significant (e.g. a major contributor) so that the overall mass is low.
Means other than adhesives may be used to secure the body to the fascia, for example mechanical fixings, friction fits or snap fit arrangements.
It will be appreciated that when adhesives are used they are chosen to effect a good adhesion between the components over the entire temperature range of operation.
It will also be appreciated that should the fascia and body have widely different coefficients of thermal expansion the means used to secure the two components together (e g. the adhesive) must be capable of withstanding the stresses exerted thereon during use of the component which will, in use with a fire, be subjected to thermal cycling regimes (e.g. when the fire is in use and switched off). *
In some cases mechanical fixings as well as, or in place of, adhesives may be used. *a *II, I,,,
The support blocks 6 may be replaced by aluminium brackets which may be screwed.. : or riveted in place.
A component made in accordance with the invention could be fabricated to provide a hearth or back panel for a fire. It could also be used to provide low weight picture frames or panels, e.g. fascia panels with a stone effect finish which would have the look and feel of solid stone but not the weight.
The component could be used with electric fires, solid fuel fires, stoves, ovens and so on as well as Class 1 and Class 2 gas fires, all of which are to be considered fires' for the purposes of this invention.
In this specification the term panel' is intended to mean an article which is self- supporting, that is an article which may bend but which can support its own weight when supported on an edge.
