Description

A Table
Field of the Invention
The present invention concerns tables. More particularly, but not exclusively, this Invention concerns table tops and methods of manufacturing table tops .
Background of the Invention
Table tops are frequently constructed from wood.
Wood is strong (particularly in the grain direction), abundantly available and can be worked with simple tools.
Wooden table tops frequently comprise a single wooden layer formed of hardwood or softwood. Such a table top is aesthetically desirable.
Wooden table tops also frequently comprise wooden veneers containing an inner layer of medium-density fibrewood (MDF) or other filler. Such table tops are lightweight and comparatively cheap to produce and imitate the appearance of a solid wooden table top.
Wood is susceptible to distortion when exposed to moisture and/or temperature change. A quarter sawn cut (having vertical end grain) taken from the centre of a tree trunk Is relatively warp stable and strong compared to a flat sawn cut (having a transverse end grain direction) taken from the outer annulus of the tree trunk. Hardwood such as oak has a smaller cell size and greater inherent warp resistance than softwood such as pine. Product quality has therefore depended principally on the selection of wood and the particular cut.
Wooden veneer table tops are often weaker and more prone to humidity-induced warping than equivalent solid wooden table tops. A wooden veneer table top typically has end panels, which enclose the MDF and wooden layers, to support the structure (aiding stability and strength) and conceal the MDF. Wooden veneers are often treated to increase water-resistance. It is generally not possible to sand a wooden veneer table top to remove defects without destroying the article.
Recent developments in the field have focussed on the application of end panels to a table-top structure. EP0446160A1 discloses cross-pieces and an outer trim strip for reducing distortion.
The prior art does not disclose a strong and warp-resistant wooden table top, having the versatility of laminated MDF but the aesthetic of a solid wooden table top .
The present invention seeks to mitigate the above-mentioned problems. Alternatively or additionally, the present invention seeks to provide an improved table top.
Summary of the Invention
According to a first aspect of the invention there is provided a table top comprising a plurality of wooden beams arranged side-by-side in an upper layer, a plurality of wooden beams arranged side-by-side in a middle layer and a plurality of wooden beams arranged side-by-side in a lower layer, wherein, the middle layer has a transverse orientation and the upper and lower layers each have a longitudinal orientation, so that successive layers are oriented orthogonally to each other .
Providing such a table top can reduce distortion upon contact with moisture and/or exposure to a high or low temperature compared to known table tops of the prior art. Providing such a table top can maximise tensile strength in every direction compared to a standard solid wooden table top and compared to other known table tops of the prior art. Providing such a table top can allow greater scope for sanding or other surface treatment compared to known table tops of the prior art.
The beams may all have the same end grain direction. The beams may have a substantially vertical end grain direction.
The table top preferably has an odd number of layers. It may be that the table top has three layers, those being the described upper, middle and lower layers. It may be that the table top has five layers, wherein there is a layer between the upper and middle layers, and a layer between the lower and middle layers. Alternatively, in the arrangement of five layers, the middle layer may be adjacent the upper layer, with three layers between the middle layer and lower layer. Alternatively, in the arrangement of five layers, the middle layer may be adjacent the lower layer, with three layers between the middle layer and upper layer.
It may be that the table top has seven layers, wherein there are two layers between the upper and middle layers and two layers between the middle and lower layers. It may be that the orientation of each successive layer alternates between a transverse and longitudinal orientation.
It may be that the upper layer has a depth of greater than 3 mm. It may be that the upper layer has a depth of greater than 5 mm. It may be that the upper layer has a depth of greater than 10 itim. It may be that the upper layer has a depth of greater than 20 mm.
It may be that the upper layer has a depth of less than 50 mm. It may be that the upper layer has a depth of less than 40 mm. It may be that the upper layer has a depth of less than 30 mm. It may be that the upper layer has a depth of less than 20 mm.
It may be that the lower layer has a depth of greater than 3 mm. It may be that the lower layer has a depth of greater than 5 mm. It may be that the lower layer has a depth of greater than 10 mm. It may be that the lower layer has a depth of greater than 20 mm.
It may be that the lower layer has a depth of less than 50 mm. It may be that the lower layer has a depth of less than 40 mm. It may be that the lower layer has a depth of less than 30 mm. It may be that the lower layer has a depth of less than 20 mm.
It may be that the middle layer has a depth of greater than 3 mm. It may be that the middle layer has a depth of greater than 5 mm. It may be that the middle layer has a depth of greater than 10 mm. It may be that the middle layer has a depth of greater than 20 mm.
It may be that the middle layer has a depth of less than 50 mm. It may be that the middle layer has a depth of less than 40 mm. It may be that the middle layer has a depth of less than 30 mm. It may be that the middle layer has a depth of less than 20 mm.
The table top may comprise hardwood and may preferably comprise oak.
Each wooden beam in the middle layer may be bonded to one or more of the wooden beams in the upper layer at the adjoining faces with glue, preferably epoxy glue.
Each wooden beam in the middle layer may be bonded to one or more of the wooden beams in the lower layer at the adjoining faces with glue, preferably epoxy glue. The process of joining may be similar to 'cold moulding'.
The table top may have a middle layer comprising twice the number of wooden beams as in the top and/or lower layers.
The table top may have a middle layer comprising eight to 12, preferably 10 wooden beams and top and lower layers each comprising four to six, preferably five wooden beams .
According to a second aspect of the invention, there is provided a method of constructing a table top wherein: a first layer is formed by joining wooden beams side by side in a longitudinal orientation with glue, preferably epoxy glue; a second layer is formed, in a transverse orientation, by fixing, one at a time, wooden beams to the first layer with glue, preferably epoxy glue; a third layer is formed, in a longitudinal orientation, by fixing, one at a time, wooden beams to the second layer with glue, preferably epoxy glue; wherein, each wooden beam has a substantially vertical end grain direction.
According to a third aspect of the invention, there is provided a table comprising a table top according to the first aspect of the invention. It may be that the table top is supported by a timber frame.
It will of course be appreciated that features described in relation to one aspect of the present invention may be incorporated into other aspects of the present invention. For example, the method of the invention may incorporate any of the features described with reference to the apparatus of the invention and vice versa.
Description of the Drawings
An embodiment of the present invention will now be described by way of example only with reference to the accompanying schematic drawings of which:
Figure 1 is an exploded plan view of a table top according to an example embodiment of the invention.
Detailed Description A table top according to an embodiment of the invention is made, from oak hardwood beams. It has overall width 50 cm, length 100 cm and depth 12 cm and comprises three layers: an upper 1, middle 2 and lower layer 3.
Each of the upper 1 and lower 3 layers comprises five longer wooden beams extending, side by side, across the length of the table top. The middle layer 2 comprises 10 shorter wooden beams extending, side by side, across the width of the table top. Each wooden beam has a substantially vertical end grain direction. Thus the table top comprises a middle layer 2 of wooden beams arranged transversely, in between an upper 1 and a lower 3 layer of wooden beams arranged longitudinally (a cross-bonded configuration).
The table top is created using a cold-moulding technique. First, the lower layer 3 is formed by fixing together five long wooden beams side by side at their adjoining edges with epoxy glue. The lower layer 3 serves as a mould. Then, one at a time, 10 short wooden beams are placed on, and affixed to, the mould to form the middle layer 2. The wooden beams are affixed with epoxy glue. Finally, one at a time, five long wooden beams are placed on, and affixed to, the middle layer 2 to form the upper layer 1. The wooden beams are affixed with epoxy glue .
The table top of this example embodiment is subsequently fitted within a timber frame to form a table .
Whilst the present invention has been described and illustrated with reference to particular embodiments, it will be appreciated by those of ordinary skill in the art that the invention lends itself to many different variations not specifically illustrated herein.
Where in the foregoing description, integers or elements are mentioned which have known, obvious or foreseeable equivalents, then such equivalents are herein incorporated as if individually set forth. Reference should be made to the claims for determining the true scope of the present invention, which should be construed so as to encompass any such equivalents.
