US Patent:
2005025, Nov 24, 2005
Filed:
May 3, 2005
Appl. No.:
11/120780
Inventors:
Andrew Marraffa - Exton PA, US
International Classification:
H05K007/16
US Classification:
361726000
Abstract:
A frame device for supporting objects such as batteries during seismic stress, comprising a pair of end frame members mounted in upstanding spaced apart relation by a plurality of vertically spaced elongated channel support members secured at opposite terminal ends to the vertical columns of the end frame members, shelves for supporting batteries spanning the channel support members and defining a plurality of compartments for the batteries, each end frame member being formed of a single sheet material shaped to define vertical columns and a web extending between the end columns, a pair of anchors, means for securing the end frames to the anchors, and means defining a plurality of openings in the web of each end frame generally aligned with the compartments formed by the shelves to provide horizontal ventilation of batteries mounted in the compartments.
