Appeal No. 2003-0677 Page 6
Application No. 09/759,950
The claims under appeal are drawn to a loading platform system for mounting
on a vehicle having a loading bed. The system comprises, inter alia, (1) a loading
platform; (2) a lift support structure with a lift actuator for raising and lowering the
loading platform between lower and upper end positions; (3) a tilt structure with a tilt
actuator for pivoting the loading platform from a horizontal to a vertical position and vice
versa; and (4) a releasable locking means for locking the loading platform in its upper
end position level with, and directly to, the loading bed, and also for releasably locking
the loading platform in the vertical position.
Randall's invention relates to loading apparatus and particularly to an improved
power operated loader adapted to be mounted on a truck or other platform to be
loaded. As shown in the drawings, a load supporting platform 34 is actuated by a
power cylinder 60 controlled by a manually actuated lever 90 so as to movable
between lower and upper end positions. As shown in Figures 1 and 3, a rotary collar 41
is provided with a manually actuated latch means indicated generally at 70 which
includes a manually actuated latch lever 72 having an inner end pivotally mounted on
beam member 22 at a pivot 74. Lever 72 includes a first latch portion in the form
of a recess 76 and a second latch portion 78 mounted on rotary collar 41 so as
to enter recess 76 when lift platform 34 is manually pivoted to the closed tailgate
position illustrated in Figure 5. Also, in the position of Figure 5 the platform 34 is
