positions articulated by the appellant and the examiner. For the reasons which follow, we
cannot sustain the examiner's rejection.
Independent claim 1 requires, inter alia, a hub "rigidly" connected to a proximal end of
a first rotating member at a first end of the hub and a proximal end of a second rotating
member disposed in an opening defined in a second end of the hub, the second rotating
member being moveable within the opening such that a distal end of the second rotating
member may move both axially with respect to the first rotating member and radially away
from a major axis of the first rotating member. Further, claim 1 requires a pin fixedly attached
to and extending through the second rotating member and engaging slots axially defined in
opposing sides of the hub, with the distal end of the second rotating member being rotatable in
a first plane about the central axis of the pin and in a second plane.
Naitou discloses a detachable universal joint comprising a hub (joint body 1) having an
opening (through hole 2) extending axially therethrough and a fixed pin (9) fastened to holes (4)
in the walls of the hub which hooks to an open end through groove (8) on the end of a first
rotating driven shaft (7). A second rotating driving shaft (5) having a pin (6) fastened therein is
received in the other end of the opening in the hub, with the pin being received in a pair of
grooves (3) in the walls of the hub. A global projection (R ), which functions as a universal
1
joint, is formed on the side of the hub opening (2) adjacent the driven shaft (7) and, in the same
manner, a global projection (R ), also performing the function of a universal joint, is pressed in
