elastic resiliency, thereby acting to reduce the rebound of the
magnet armature due to impact vibrations.
Claim 9 is illustrative of the invention and reads as follows:
9. A switchgear housing for an electromagnetic switching device
including a magnet yoke and a magnet armature, comprising:
a magnetic chamber including a vibratable magnetic-chamber
base, the magnetic-chamber base having a surface including a
supporting strip, the surface facing an interior space of the
switchgear housing, the supporting strip including a first end
configured as a first magnet-supporting area and a second end
configured as a second magnet-supporting area, the first magnet-
supporting area having a first elastic resiliency and the second
magnet-supporting area having a second elastic resiliency, the
first elastic resiliency being different from the second elastic
resiliency, the first magnet-supporting area being retained at the
first end only by the magnetic-chamber base;
wherein the first magnet-supporting area and the second
magnet-supporting area support the magnet yoke, and the magnet
armature is positionable in the magnetic chamber.
The Examiner relies on the following prior art:
Lemmer 4,229,719 Oct. 21, 1980
Schmiedel et al. (Schmiedel) 4,647,886 Mar. 03, 1987
Sitar 5,623,239 Apr. 22, 1997
(filed Jan. 17, 1996)
Claims 9-17 stand finally rejected under 35 U.S.C. § 102(b) as
being anticipated by each one of Schmiedel and Lemmer. Claims 9-11
and 13-17 also stand finally rejected under 35 U.S.C. § 102(e) as
being anticipated by Sitar.
