Two-position locking device for a support fixture

A support fixture for supporting a plurality of components on a shipping rack, said support fixture comprising:

• a frame;
• a plurality of fingers each pivotally coupled to the frame for movement about a pivot between a support position and a released position, each finger having a front end and a back end extending from substantially opposite sides of a pivot wherein the front end is presented for supporting one of the components in the support position, the plurality of fingers being arranged in a stack with a first finger being disposed at an end of the stack, each of the plurality of fingers including a boss extending outwardly therefrom to hold an adjacent finger in the support position;
• and
• a locking device having a pin that is axially movable between an extended position disposed along the back end of the first finger to hold the first finger in the support position and a retracted position spaced apart spaced apart from the first finger to allow pivotal movement of the first finger between the support and released positions, the locking device further having
• a button operatively coupled to the pin to cause alternating actuation of the pin between the extended and retracted positions with each push of the button toward the pin, the button extending outwardly from the frame and moving axially with the pin during movement between the extended and retracted positions to facilitate external visual identification of the position of the pin.
