For the reasons stated above, the decision of the
examiner to reject claims 1 and 2 under 35 U.S.C. § 103 is
affirmed.
Claims 3, 5 to 8, 31 and 33 to 38
Claims 3, 6 and 36 and the claims dependent thereon
(i.e., claims 5, 7, 8, 31, 33 to 35, 37 and 38) recite that
one of the interlocking means include a ramp means formed on
the back plate and a locking tab means formed on the top or
bottom member. Claims 3, 6 and 36 further recite that the tab
means is adapted to be moved into engagement with the ramp
means by movement of the top or bottom member generally
transverse to the back plate until the tab means having been
compressed by the movement, disengages the ramp means.
