Abstract

A chair stock such as a seat 12 includes a construction in which uppermost and lowermost wood veneer sheets 30, 32 present opposing support and mounting surfaces 20, 22, and are spaced from one another by an intermediate element 34 such as a pile of relatively small wood veneer sheets 36. The intermediate element 34 presents a bearing surface that corresponds in size to a planer central region 28 of the mounting surface 22, and the support surface 20 includes a curved central region directly opposite the planer central region. The stock is constructed by forming a pile of the sheets 30, 32 and the intermediate element 34, and pressing the pile between a pair of spaced apart pressing surfaces. One of the pressing surfaces includes a substantially planer central region aligned with and corresponding in size to the bearing surface of the intermediate element, and the other pressing surface includes a curved central region immediately opposite the planer central region.

Claims

1. A wood veneer stock for use in a chair, comprising:

a first wood veneer sheet presenting a mounting surface including a substantially planer central region;

a second wood veneer sheet presenting a support surface including a curved central region immediately opposite the planer region of the mounting surface; and

at least one intermediate wood veneer sheet interposed between the central regions of the first and second sheets, the intermediate sheet corresponding in plan size to the planer central region of the mounting surface.

2. The wood veneer stock as recited in claim 1, further comprising an adhesive composition intermediate the sheets.

3. The wood veneer stock as recited in claim 1, wherein the intermediate wood veneer sheet and the central region of the mounting surface are generally rectangular in plan shape.

4. The wood veneer stock as recited in claim 1, wherein the stock is a chair seat.

5. A chair stock for use in a chair, comprising:

a first wood veneer sheet presenting a mounting surface including a substantially planer central region;

a second wood veneer sheet presenting a support surface including a curved central region immediately opposite the planer region of the mounting surface; and

at least one intermediate element interposed between the sheets and aligned with the central regions of the mounting and support surfaces, the intermediate element presenting a generally planer bearing surface corresponding in size to the planer central region of the mounting surface.

6. The chair stock as recited in claim 5, wherein the intermediate element is wood.

7. The chair stock as recited in claim 5, wherein the intermediate element includes a pile of wood veneer sheets.

8. The chair stock as recited in claim 5, further comprising an adhesive composition applied between the sheets and the intermediate element for securing the sheets and the intermediate element together.

9. The chair stock as recited in claim 5, wherein the intermediate element and the central region of the mounting surface are generally rectangular in plan shape.

10. The chair stock as recited in claim 5, wherein the stock is a chair seat.

11. A method of making a stock for use in a chair, comprising the steps of:

forming a pile of at least a first wood veneer sheet presenting a mounting surface, a second wood veneer sheet presenting a support surface, and an intermediate element interposed between the first and second sheets, the intermediate element including a planer bearing surface of a size smaller than the mounting and support surfaces;

pressing the pile between first and second spaced apart pressing surfaces, wherein the first pressing surface engages the mounting surface of the pile and includes a substantially planer central region aligned with and corresponding in size to the planer bearing surface of the intermediate element, and the second pressing surface engages the support surface and includes a curved central region immediately opposite the planer central region of the first pressing surface.

12. The method as recited in claim 11, wherein the intermediate element is wood.

13. The method as recited in claim 11, further comprising the step of forming the intermediate element of a pile of wood veneer sheets.

14. The method as recited in claim 11, further comprising the step of applying an adhesive composition between the sheets and the intermediate element prior to the forming step.

15. The method as recited in claim 11, wherein the intermediate element and the central region of the mounting surface are generally rectangular in plan shape.
