Motion furniture mechanism with pre-aligned linkage member
A motion furniture side mechanism includes a side plate and a pivotable swing arm pre-aligned with the side plate for insertion of a driver tube using an automated or manual assembly operation. The swing arm includes a pivotable driver arm, and a driver tube socket is defined on the driver arm. One or more bushings disposed between the side plate and the swing arm or driver arm provides a mechanical retainer to prevent the swing arm or driver arm from becoming inadvertently angularly misaligned prior to assembly. The pre-aligned side mechanism allows automated insertion of a driver tube without the need to identify a misaligned linkage or re-align a linkage prior to driver tube insertion. A method of assembly furniture includes providing a side mechanism with a pre-aligned linkage member such as a swing arm or driver arm positioned for driver tube insertion.
1. A furniture apparatus, comprising:
a side mechanism having a side plate and a pivotable swing arm;
a driver arm disposed on the swing arm;
a driver tube socket defined in the driver arm;
a driver tube hole defined in the side plate;
a side plate bushing disposed on the side plate, the side plate bushing co-axially aligned with the driver tube hole;
a driver arm bushing disposed on the driver arm, the driver arm bushing co-axially aligned with the side plate bushing;
a driver arm fastener flange extending from the driver arm toward the side plate; and
a driver arm bushing flange extending from the driver arm fastener flange and a driver arm bushing flange hole defined through the driver arm bushing flange, wherein the driver arm bushing flange hole is co-axially aligned with the driver tube hole,
wherein the driver arm bushing is disposed in the driver arm bushing flange hole.
2. The apparatus of claim 1 , wherein the driver tube socket is rectangular.
3. The apparatus of claim 1 , further comprising a rim disposed on the side plate bushing, wherein the rim forms an axial stop for the side plate bushing.
4. The apparatus of claim 1 , wherein the driver arm fastener flange is oriented at about ninety degrees relative to the driver arm.
5. The apparatus of claim 1 , wherein the driver arm bushing flange is oriented at about ninety degrees relative to the driver arm fastener flange.
6. The apparatus of claim 1 , further comprising a driver tube disposed through the side plate bushing and driver arm bushing.
7. The apparatus of claim 6 , wherein the driver tube is received in the driver tube socket.
8. The apparatus of claim 7 , further comprising a plurality of resilient side flange bushing tabs extending through the driver arm bushing.
9. The apparatus of claim 8 , further comprising a plurality of driver arm bushing tabs extending through the driver arm bushing flange hole.
10. The apparatus of claim 9 , wherein the side flange bushing tabs also extend through the driver arm bushing flange hole.
