Appeal No. 97-2888 Application 08/389,077 may be adjusted by controlling the depth that the mounting rods 42 are inserted in the rail clamps 44 (see col. 4, lines 10-13). Accordingly, we will sustain the § 103 rejection of claim 36 based on Michelson '943, Heffington and Michelson '892. We will not, however, sustain the § 103 rejection of claims 2-5, 7, 13-15, 19, 23, 33, 40 and 43 based on Michelson '943 in view of Heffington. Claim 2, as well as claims 3-5 and 7 dependent therefrom, and claims 19 and 33 recite first and second side frame members each comprising a forward vertical member, a bottom horizontal member, a top horizontal member parallel to the bottom horizontal member, a rearward vertical member parallel to the forward vertical member and an angled rearward member connected to the top horizontal member and to the rear vertical member, i.e., a five-sided closed loop construction. 18Page: Previous 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 NextLast modified: November 3, 2007
