Abstract
Abstract An earthquake backstop support for mobile homes includes a cross-beam which underlies the pier-supported underframe of the home in closely spaced relationship to, but separated from, the underframe. In the event of displacement of the home from its piers, the beams of the backstop support support it in a level attitude and are carried on slidable shoes so as to permit sliding movement during continuing earthquake shocks.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
53 words
A backstop support for a mobile home having an underframe; said support comprising a cross-beam, adjustable means for supporting said cross-beam in a position underlying but spaced from said underframe, and means for preventing relative displacement of said cross-beam and underframe longitudinally of said cross-beam when said cross-beam is supported in said position.
Claim 2
Dependent Claim
53 words
A backstop support for a mobile home having an underframe; said support comprising a cross-beam, adjustable means for supporting said cross-beam in a position underlying but spaced from said underframe, and means for preventing relative displacement of said cross-beam and underframe longitudinally of said cross-beam when said cross-beam is supported in said position.
Claim 3
Dependent Claim
45 words
A backstop support according to claim 1 in which said last-named means comprises end plates secured to said beam and having portions extending upwardly with respect to said beam into positions in which they bracket said underframe when said cross-beam is supported in said position.
Claim 4
Dependent Claim
39 words
A backstop support according to claim 1 in which said first-named means comprises a pair of end supports for said cross-beam each including an elongated shoe having a flat under surface adapted for sliding movement over an underlying support.
Claim 5
Dependent Claim
39 words
A backstop support according to claim 2 in which said first-named means comprises a pair of end supports for said cross-beam each including an elongated shoe having a flat under surface adapted for sliding movement over an underlying support.
Claim 6
Dependent Claim
40 words
A backstop support according to claim 1 in which said first-named means includes end plates secured to said beam, paralleling support plates, and means for interconnecting said plates in selected relatively offset relationships to support said beam at selected heights.
Claim 7
Dependent Claim
43 words
A backstop support according to claims 2, 3 or 4 in which said first-named means includes end plates secured to said beam, paralleling support plates, and means for interconnecting said plates in selected relatively offset relationships to support said beam at selected heights.
