Coil spring bracket

摘要

A coil spring bracket assembly that supports a cushion on a furniture frame is disclosed. A flat spring spans the furniture frame along a support plane to support the cushion. A cross member spanning the furniture frame is aligned with and spaced from the flat spring. A helical spring extends from the cross member to the flat spring to bias the flat spring toward the support plane. A bracket is disposed at opposite ends of the cross member to anchor the cross member to the furniture frame. The bracket includes a top portion that extends outwardly over the furniture frame along the support plane, a middle portion that extends from the top portion into the furniture frame, and a bottom portion that extends inwardly from the middle portion to abut a portion of the cross member in overlapping relationship.

主权项

1. A coil spring bracket apparatus that supports a cushion on a furniture frame comprising:
at least one flat spring spanning the furniture frame, said at least one flat spring extending between two opposite ends and along a support plane wherein the cushion is supported on said support plane; at least one cross member spanning the furniture frame that extends between two opposite ends and that is aligned with and spaced from said at least one flat spring; at least one helical spring extending from said at least one cross member to said at least one flat spring to bias said at least one flat spring toward said support plane; a bracket disposed at each of said two opposite ends of said at least one cross member anchoring said at least one cross member to the furniture frame; said bracket including a top portion extending outwardly over the furniture frame along said support plane to an outboard edge, a middle portion extending from said top portion into the furniture frame, and a bottom portion extending inwardly from said middle portion to abut a portion of said at least one cross member in an overlapping relationship; a spring clip disposed at each of said two opposite ends of said at least one flat spring anchoring said two opposite ends of said at least one flat spring to the furniture frame; and a cut-out, centrally located in said top portion of said bracket, that extends to said outboard edge of said top portion of said bracket such that said cut-out is open to said outboard edge of said bracket and receives said spring clip in interleaving engagement.
