  • Patent number: 5299766
    Abstract: A retrofit bracket for wall mount speakers has a support surface configured for mounting at least one speaker thereto and a pair of elongate clamping bars extending across to opposite sides of the rear of the support surface and adjustably attach thereto such that a wall covering is clampably capturable intermediate the support surface and the bars. An adjustment means facilitates varying of the distance between the support surface and the bars to accommodate various wall covering thicknesses. The elongate bars are sufficiently flexible to provide spring tension against the wall covering captured intermediate the bars and the support surface. A foot is formed upon each end of the elongate bars for distributing the force applied by the bars over an increased surface area. The use of feet to spread the force of the bars over an increased surface area mitigates the potential for compression of the wall covering captured therebeneath.
    Type: Grant
