Appeal No. 1999-0636 Page 14
Application No. 08/828,375
Turning finally to the examiner's rejection of claims 25
and 9 under 35 U.S.C. § 103 as being unpatentable over
Johnston in view of La Mell, Johnston discloses a closure
structure for closing a doorway comprising a housing means
(box-like enclosure 17) and a reel or spool of closure
material (18) bordered at one end by a stabilizing member (19)
provided with supporting wheels (24) at the upper end thereof
adapted to travel in a guide means (23) of a track hanger (22)
mounted to the top of the doorway. The closure material (18)
is disclosed as being screen cloth, vinyl "or other plastic
suitable for storm door usage" (column 1, lines 58-62). The
box-like enclosure (17) is mounted to the door jamb (12) and a
strip (37) of magnetic material is mounted to the other door
jamb (13). As explained in column 2, lines 41-50, the
magnetic material enables the jamb (13) to releasably maintain
the closure in the closed position, such that application of a
sufficiently hard force will cause the closure to disengage
from the magnetic material and automatically retract to
protect the closure whereas mere high winds will not cause the
closure to retract.
