Abstract

Motion furniture includes a frame with a side mechanism having a torsion activator that may be actuated by a user to impart a motion on a frame member or to bias a frame member in a desired position. The torsion activator includes an activator bracket and an activator arm pivotally attached to the activator bracket. A torsion spring is disposed between the activator arm and the activator bracket. The activator bracket is configured for attachment to a frame member on the side mechanism, such as a seat plate. The torsion activator includes an activator bracket having proximal and distal ends, and one or more press-fit fasteners are disposed on each of the proximal and distal ends of the activator bracket. Each press-fit fastener is configured for insertion into a corresponding hole on the frame member allowing uni-directional installation of the torsion activator using manual or automated assembly.

First claim

What is claimed is:

1. A furniture apparatus, comprising:
a side mechanism including a linkage member;
a torsion activator disposed on the side mechanism, the torsion activator including a proximal end and a distal end;
a first push fitting protruding from the proximal end of the torsion activator toward the linkage member;
a second push fitting protruding from the distal end of the torsion activator toward the linkage member;
a first hole defined in the linkage member, wherein the first push fitting is received in the first hole; and
a second hole defined in the linkage member, wherein the second push fitting is received in the second hole,
wherein the first push fitting is integrally formed in the torsion activator.

2. The apparatus of claim 1 , wherein the second push fitting is integrally formed in the torsion activator.

3. The apparatus of claim 2 , further comprising:
the torsion activator including an activator bracket and an activator arm pivotally attached to the activator bracket.

4. The apparatus of claim 3 , wherein the activator bracket is substantially flat along a first plane.

5. The apparatus of claim 4 , wherein the first push fitting extends from the activator bracket in a direction substantially normal to the first plane.

6. The apparatus of claim 5 , wherein the second push fitting extends from the activator bracket in a direction substantially normal to the first plane.

7. The apparatus of claim 6 , wherein the first push fitting, second push fitting and activator bracket are integrally formed as a single member.

8. The apparatus of claim 7 , wherein the first push fitting, second push fitting and activator bracket comprise a unitary injection molded polymer.

9. The apparatus of claim 8 , wherein the second push fitting includes a Christmas-tree style press rivet.

10. The apparatus of claim 9 , wherein the first push fitting includes one or more resilient tabs.

11. The apparatus of claim 10 , further comprising a torsion spring disposed between the activator bracket and the activator arm.

12. The apparatus of claim 11 , further comprising an activator flange protruding from the activator arm.

13. The apparatus of claim 12 , further comprising a pivot disposed between the activator bracket and the activator arm.

14. A furniture apparatus, comprising:
a side mechanism including at least one linkage member;
a torsion activator disposed on the linkage member, the torsion activator including a proximal end and a distal end;
an activator bracket on the torsion activator configured for attachment to the linkage member;
an activator arm pivotally attached to the activator bracket;
an activator flange protruding from the activator arm;
a first press-fit fastener protruding from the proximal end of the torsion activator toward the linkage member;
a second press-fit fastener protruding from the distal end of the torsion activator toward the side plate,
wherein the first and second press-fit fasteners are integrally formed with the activator bracket as a unitary piece.

15. The apparatus of claim 14 , further comprising a first hole defined in the linkage member, wherein the first press-fit fastener is received in the first hole.

16. The apparatus of claim 15 , further comprising a second hole defined in the linkage member, wherein the second press-fit fastener is received in the second hole.

17. The apparatus of claim 16 , wherein the first press-fit fastener extends perpendicularly from the activator bracket.

18. The apparatus of claim 17 , wherein the second press-fit fastener extends perpendicularly from the activator bracket.

19. The apparatus of claim 18 , wherein the first press-fit fastener, the second press-fit fastener and the activator bracket comprise a unitary injection molded polymer.
