Appeal 2006-2289
Application 10/812,266
The claimed invention is directed to a threaded fastener for two types of
electronic equipment mounting rails. The fastener has a circular stepped portion on
the bottom planar surface of the head. The stepped portion is sized so it will just
fit in the square hole of the second type of mounting rail.
Claim 1, reproduced below, is further illustrative of the claimed subject
matter.
1. A fastener, comprising:
a shank having a threaded portion;
a head portion having a top surface, a planar bottom
surface, and a diameter, and
a stepped portion between the head portion and the
threaded portion, the stepped portion having a diameter that is
larger than the diameter of a round hole in a first type of
mounting rail and smaller than a length of a side of a square
hole in a second type of mounting rail, wherein when the
fastener is inserted into one of the round holes of the first type
of mounting rail a bottom surface of the stepped portion is
urged against a front surface of the first type of mounting rail,
and when the fastener is inserted into one of the square holes of
the second type of mounting rail the stepped portion enters
closely into the square hole and the planar bottom surface of the
head portion is urged against a front surface of the second type
of mounting rail.
The reference of record relied upon by the Examiner as evidence of
obviousness is:
