Abstract
Abstract A bracket mechanism including an upper brace and a lower brace for mounting a support member, such as an ironing board, desk, table, drawing board, or the like, in either a substantially horizontal operative position or a substantially upright inoperative position. The braces are mounted for swinging movement in a cabinet in which the bracket mechanism and support member are stored, in the folded positions of said parts. The cabinet also provides in part a support for the swingably mounted braces. A latch means retains the support member and braces in the operative positions of said parts and is manually releasable to enable said parts to swing to folded storage positions.
