Abstract

A method and apparatus for applying tension to a fabric decking on an article of furniture are described. The apparatus includes a cylindrical base having a central axis and that is adapted to be placed in proximity to a frame of the article of furniture. A plurality of spaced needles are coupled to, and extend away from, said base. The needles are aligned in a row parallel to the axis of the cylindrical base. The needles extend away from the base a distance greater than a thickness of the fabric decking material. The apparatus also includes a rotation mechanism coupled to the base and operable to impart a rotational movement to the base about the axis, between a first, ready position for engagement with the fabric decking material, and a second stretched position.

Claims

1. An apparatus for installing a fabric decking material in an article of furniture, the apparatus comprising:

a cylindrical base having a central axis and adapted to be placed in proximity to a frame of the article of furniture;

a plurality of spaced needles extending away from said base and aligned in a row parallel to said axis of said cylindrical base, said needles extending a distance greater than a thickness of the fabric decking material; and

a rotation mechanism coupled to said cylindrical base and operable to impart a rotational movement to said cylindrical base about said axis, between a first, ready position for engagement with the fabric decking material, and a second stretched position.

2. The apparatus of claim 1, wherein the rotation mechanism is a handle.

3. The apparatus of claim 2, wherein the handle extends from a midpoint along the cylindrical base, said handle spaced from said needles about the circumference of said cylindrical base.

4. The apparatus of claim 2, wherein the cylindrical base has opposed first and second ends, and wherein the handle extends from said cylindrical base proximate one of the first and second ends.

5. The apparatus of claim 1, wherein the cylindrical base has opposed first and second ends supported by a pair of spaced end supports that allow rotation of the cylindrical base about the axis, the apparatus further comprising a locking collar disposed on one of said first or second ends, and a locking lever coupled adjacent said locking collar, said locking lever engaging said locking collar upon rotation of said cylindrical base to said second stretched position.

6. The apparatus of claim 5, further comprising a biasing spring having a first spring end coupled to the first or second end, opposite said collar, and a second spring end coupled to the adjacent end support, said biasing spring operable to return said cylindrical base from said stretched position to said first, ready position.

7. The apparatus of claim 1, wherein the cylindrical base has opposed first and second ends, one of said first and second ends being coupled to a powered rotational mechanism that, upon activation, rotates said cylindrical base between said first and second positions.

8. The apparatus of claim 7, wherein the rotational mechanism is a gas cylinder coupled to one of said first or second ends with a rack and pinion coupling that transfers linear motion of said gas cylinder into rotational movement of said cylindrical base.

9. The apparatus of claim 7, further comprising a plate hingedly coupled above said cylindrical base and positioned to extend over said needles when said plate is in a closed position.

10. The apparatus of claim 9, further comprising a rail coupled to said plate and extending downwardly therefrom, said rail positively engaging said needles through said fabric when said plate is in said closed position.

11. A method for installing a deck assembly in an article of furniture, the method comprising:

in a frame having a front rail, a rear rail and opposed sides extending between said front and rear rails, attaching a fabric decking material along said rear rail of said frame;

extending the material from said rear rail and over said front rail;

securing at least a portion of said material forwardly of said front rail in a rotational tool having extending needles that puncture said fabric;

applying a rotational force on the rotational tool to stretch the decking between the front rail and the rear rail; and

attaching the material to the front rail while in the stretched condition.

12. The method of claim 11, wherein the decking comprises an elastomeric textile.

13. The method of claim 12, further comprising locking the rotational tool in place in the stretched position before attaching the material to the front rail.

14. The method of claim 12, wherein applying the rotational force includes activating a gas cylinder operably coupled to the rotational tool.

15. An apparatus for installing a fabric decking material in an article of furniture, the apparatus comprising:

a base having upstanding first and second end supports;

an engagement section extending between the first and second end supports and having a central axis and adapted to be placed in proximity to a frame of the article of furniture;

a plurality of spaced needles extending away from said engagement section and aligned in a row parallel to said axis of said section, said needles extending a distance greater than a thickness of the fabric decking material; and

a powered rotation mechanism coupled to said engagement section and operable to impart a rotational movement to said section about said axis, between a first, ready position for engagement with the fabric decking material, and a second stretched position.

16. The method of claim 15, wherein said powered rotation mechanism is a gas cylinder.

17. The method of claim 16, further comprising a plate hingedly coupled above said engagement section and positioned to extend over said needles when said plate is in a closed position.

18. The apparatus of claim 17, further comprising a rail coupled to said plate and extending downwardly therefrom, said rail positively engaging said needles through said fabric when said plate is in said closed position.
