Appeal No. 96-0162
Application 08/030,806
coupling for connecting driving and driven rotary members. Claim
1 is exemplary of the subject matter on appeal and recites:
1. A flexible coupling for connecting driving and
driven rotary members the rotational axes of which may be
slightly misaligned relative to one another, said coupling
comprising a first connecting means for connecting said coupling
to said driving member, a second connecting means for connecting
said coupling to said driven member, and at least one rectangular
flex frame connected between said first connecting means and said
second connecting means, said at least one flex frame having four
legs consisting of two short legs generally identical and
parallel to each other and two long legs longer than said short
legs which long legs are generally identical and parallel to each
other and generally perpendicular to said short legs, said legs
of said at least one flex frame having cross sections of such
dimensions that the stiffness of said coupling with respect to a
bending moment applied between said first connecting means and
said second connecting means in a plane containing said
rotational axes of said driving and driven members is
substantially uniform for all angles of said plane about said
rotational axis of said driving member.
