Adjustable stair stringer and railing

A riser/tread support bracket and aligning/spacing means kit for use with duplicate kits in an adjustable stair assembly for at least one side of a stairway, said stair assembly having a pair of parallel stringers at said at least one side, a plurality of said support brackets adjacent to each other along said parallel stringers, and said aligning/spacing means of said kit being adapted for spacing and aligning said support bracket of said kit with respect to adjacent support brackets from said duplicate kits along said parallel stringers and for spacing said parallel stringers:

• said support bracket of said kit comprising,
• a) a support bracket having a tread support surface and at least a reference surface having engagement means, and means for accomodating fastening means,
• b) said means for accomodating fastening means comprising a pair of holes in said support bracket, one of said pair of holes being adapted and aligned for pivotally attaching said support bracket to one of said spaced parallel stringers, the other of said pair of holes being adapted and aligned for pivotally attaching said support bracket to the other of said parallel stringers,
• said aligning/spacing means of said kit comprising,
• c) an elongated member having a first element at each end thereof, said first element at one end of said elongated member cooperating with said engagement means of said support bracket and establishing a non-rotatively fixed positioning of said support bracket with said aligning/spacing means for distance and direction alignment and spacing of said support bracket with respect to an adjacent duplicate support bracket of a duplicate kit along said parallel stringers, and
• d) a second element integrally connected to said elongated member and extending laterally from a side surface of said elongated member, said second element extending beyond a side of said support bracket for insertion between said parallel stringers to establish a spacing and lateral positioning of said parallel stringers with respect to said support bracket and aligning/spacing means,
• whereby said support bracket of said kit is adapted to be pivotally attached to said spaced parallel stringers, is adapted to be spaced from another support bracket of a duplicate kit by said first element of said aligning/spacing means, and adapted to be pivotally movable with parallel surfaces of said spaced parallel stringers.
