release position shown in phantom outline in fig5 the arm 74 is also rotated the pin 80 escapes from the depression 81 and is rotated with the arm 74 to the panel release position in which the pin 80 encounters a hole 86 extending through the bracket 73 and the end 71 of the compartment 20 thus the arm 74 and consequently the lever 69 and the bar 14 are locked in the panel release position referring to fig2 and 3 a plurality of ejectors 88 are provided on the interior of the frame 4 the ejectors 88 are spring loaded plungers for biasing the panel 8 outwardly from the frame 4 immediately following release of the panel 8 by the latches 10 the ejectors 88 push the panel 8 outwardly to clear the opening 6 in operation one or more bars of the actuation mechanism is pulled towards the operator and away from the limit positions defined by the detent pin 80 the depression 81 and the hole 86 rotation of a bar 14 causes pivoting of a lever 26 on one end of the bar 14 and consequently rotation of the shafts 31 and 29 and the pinion 40 rotation of the pinion 40 results in movement of the rack 42 and the cable 45 which translates into rotation of all of the levers 54 to release the latches 10 the panel 8 is thus free to move and is.
