of slope portion 118. Upon full insertion, the latching hook
surface 120 of the projection spar 116 fits within the
aperture 132 of the socket receptacle on molded projection 128
permanently locking the projection spar 116 in a fixed
position. The biasing tip 130 maintains the molded projection
126 firmly against projection spar 116. Similarly, the
reinforced lower portion 122 of the spar 116 permits
deflection only during assembly and remains fixed in its
upright position to prevent disengagement of the latching hook
surface 120 from the aperture 132. Alignment boss 134 fits
within slot 124 forming a tongue and groove assembly
preventing access to the now locked components with the
latching means hidden from external view.
After the scope and content of the prior art are
determined, the differences between the prior art and the
claims at issue are to be ascertained. Graham v. John Deere
Co., 383 U.S. 1, 17-18, 148 USPQ 459, 467 (1966).
