Appeal No. 2003-0092
Application No. 09/432,525
a sensor mechanism mounted on the base and affecting a
perimeter of the base; and
a guard operably connected to the base and mounted over said
sensor mechanism and adapted to activate the sensor mechanism
when pressure is exerted upon the guard;
thereby providing a means for interrupting a descent of the
platform in response to an object encroaching said perimeter of
the base and exerting pressure on the guard.
The examiner relies upon the following references as
evidence of obviousness:
Martin 3,466,411 Sep. 09, 1969
Yeakle 5,379,655 Jan. 10, 1995
Kemmerer et al. 5,931,532 Aug. 03, 1999
(Kemmerer)
Appellant's claimed invention is directed to a lift table
comprising, inter alia, a sensor mechanism mounted on the base
having a guard operably connected to the base and mounted over
the sensor mechanism. When pressure is exerted upon the guard,
the descent of a platform is interrupted as a safety measure.
Appealed claims 1, 4-6, 8-13, 15 and 20 stand rejected under
35 U.S.C. § 103 as being unpatentable over Yeakle in view of
Kemmerer. Claims 14 and 16-19 stand rejected under 35 U.S.C.
§ 103 as being unpatentable over Yeakle in view of Kemmerer and
Martin.
