Appeal 2006-2711
Application 10/662,935
Appellant invented a joint for a shower arm arrangement. The joint
allows two links to pivot relative to one another, but the joint itself is less
likely to rotate than other joints in the prior art (Specification 1). Claim 13
is illustrative of the invention and reads as follows:
13. A pivot connection for a shower comprising:
a pair of links, said links being hollow and
allowing passage of water through said links to a
showerhead;
one of said links including an end wall, with
a cup extending from said end wall, and a threaded
member immovably fixed to said end wall and
extending through and beyond said cup;
the other of said links including a hollow
cylindrical member abutting said cup, with a nut
attached to said threaded member on an opposed
side of said hollow cylindrical member from said
cup, with said threaded member being immovably
fixed to said end wall; and
wherein the immovability of said threaded
member is independent of the attachment of said
nut.
The Examiner relies upon the following as evidence of
unpatentability:
