ARTICLES
BACKGROUND OF INVENTION The present invention relates to artificial timbers particularly so called particle board or medium density fibre board. The invention even more specifically is directed to dressed artificial timbers.
DESCRIPTION OF PRIOR ART A problem with artificial timbers is that they a.e relatively weak particularly when one endeavours to fix other components or parts to the artificial timbers as occurs with door frames, cupboard doors, window frames and similar areas where artificial timber is utilised.
Laminated plywood timber is well known in panelling work. The central core of plywood is usually of solid timber and provides strength whilst still retaining s o m e fle xibility. Plywoods, otherwise known as "3 Ply" are well known 15 and do not merit further discussion here.
j Other laminated timbers include floor boards or parquetry flooring and an example is disclosed in US Patent Number US 3,888,061 disclosing oblong panels of wood boards including an interengaging, strengthening solid timber -edge fillet in grooves for interconnecting said boards in a tongue and groove fashion. A somewhat similar arrangement is disclosed in German Specification Number 3309645 showing a composite wooden panel with solid timber inserts to secure the panels together for forming decorative walls and ceilings and the g ,lik e 5 The disclosure in US Patent Number 4,122,236 discloses a.board of artificial timber in which aligned hardwood splinters are compressed together with adhesive to form an elongated board forming an artificial timber of comparable strength to natural timbers.
Such prior art arrangements do not address the problem set out to be overcome by the present invention, namely of utilizing artificial timbers as a replacement for dressed natural timbers having adequate strength and fixing characteristics.
SUMMARY OF THE INVENTION The objective of the invention is to address at least one of the problems of the prior art.
According to an embodiment of the present invention there is provided an artificial timber article having one or more reinforcing portions, the reinforcing portions positioned so as to be capable of receiving one or more fixing means.
More specifically the present invention provides an artificial timber article of particle board or medium density fibre board including a reinforcing strip of solid timber at least along an edge portion or portions of the timber article into which fixing means such as screws, nails or the like may be affixed. The dimension of the strip and the location thereof is such that the fixing means may penetrate said reinforcing strip to achieve a fixing strength substantially equivalent to fixing to an article wholly made of solid timber.
The strengthened artificial timber article according to the present S 15 invention may be dressed and may be used in applications normally confined to dressed timber articles, thereby providing a cheaper alternative while maintaining a substantially equivalent fixing strength.
Examples of solid timbers that the present invention may be used to Sreplace are kiln dried hardwoods and softwoods which are relatively expensive materials.
The present invention further provides a method of strengthening or modifying an artificial timber article for application of fixing means, the method including the steps of forming a groove in the artificial timber article at-least partially along one or more sides thereof, and fitting a strip of reinforcing material into the groove or grooves; The present invention is to provide a strengthened artificial timber article and method of producing such an article, wherein the article is suitable for use as a replacement for solid timbericmponents such as door frames, window frames, cupboards, furniture and riitraves. It has been found that fixing screws and the like to artificial timbers is.i adequate as the timbertends to disintegrate around the fixing screws. This is avoided by the present invention.
.z 3'.
m or artificial timber. Ths is The invention is based on strengte.ningcustm or artificial timber. This is accomplished by integrating or insetting solid timber, DETAILED DESCRIPTION F TEJNI With reference to figure 1, there is illustrated an example of an artificial timber article according to the invention in which a piece of artificial timber, such as particle board or medium density fibre board custom wood) 10 is grooved along two edges and strips of solid timber 11 a and 11 b, preferablY of hardwood, are inserted snugly into the grooves. The solid mber may be affixed in the grooves with wood adhesive. the aificia timber the 0 By inserting solid timber along the edges of the artificial timber has increased strength and is capable of receive fixing means with reduced risk of splintering or breakage.
By placing the solid timber inserts along two opposite edges the timber article may be used in either orientation. It is noted, however, that the inserts ncrti e formed, the resultin timber article 1 may be sawn or worked in the usual manner the r article 1 has a hinge 12 fitted to an a door frame, window frame or the like.
It will beappreciated that the solid timber insert may be of any shape or dimnsion. The only requirement is to ensure that the fixing means, in this embodiment being screws, are embedded and affixed into the insert.
In another embodiment of the invention (not illustrated), holes may be bored down one or ore sides of the artificial timber article for the solid timber to be inserted into. Through this embodiment of the invention, ifis apparent that as long as the solid timber is inserted into the region in which fixing means are to be affixed, then the solid timber inserts may be applied in any manner.
Artificial timbers.such as medium density fibre board or particle board lend themSe!ves to moulding techniques for use as a dressed timber substitute i i a such as for door and window frames, architraves, cupboards and cabinets. The present invention seeks to overcome 1 major disadvantage with such timbers in providing an adequate fixing system that avoids premature breakage. The artificial timber article according to the present invention is a viable price competitive alternative to solid dressed timbers traditionally used in these situations.
