Appeal No. 96-4021
Application 08/289,300
FIG. 2 shows a bottom view of one of the
two arm-supports 25. A plate 27 is fixed to
the frame-part 26 and is provided with a
longitudinal channel 28. The arm-support 25
has at its under side a plate 29 provided
with a channel 30 extending at right angles
to the channel 28. A hook bolt extends into
the channel 28 and may be fixed to the arm-
support 25 by means of a coupling nut 31.
Since the channels 28 and 30 extend at right
angles towards each other, the arm-supports
25 may be adjusted at right angles to each
other in two extending directions [column 3,
lines 19 through 29].
The channel 28 is actually a slot in the plate 27 which
receives the hook bolt so as to allow the armrest or arm-support
25 to be moved along the frame-part 26 linearly with respect to
the seat of the chair.
Danziger discloses a wheelchair having an armrest
assembly 2 which includes a “gallows-like arm 14 the vertical
portion of which is turnable” (column 2, lines 15 and 16). The
arm 14 has an upright lower portion and an upper portion which
extends transversely to the upright lower portion. This arm is
turnable or rotatable about the central axis of the upright lower
portion to allow the occupant of the chair to transfer laterally
to a bed or car (see column 2, lines 25 through 35).
Hough discloses an armrest assembly 10 having an
armrest element 36 which is adjustably mounted for linear
