Work Platform Is Supported by Self-Locking Blades

The problem: 
In the engine bay area of the Saturn S-I!, a work 
platform is required for the installation, inspection, 
and maintenance of equipment. Such a platform must 
be rigidly supported when in place but must also be 
capable of being quickly moved out of the way when 
not in use.
structure when lowered into place. The supporting 
plate is attached to a number of blades that are hinged 
to the platform in such a way that they latch in the 
horizontal (down) position to support the platform 
by means of the plate, and may be unlatched and 
moved upward through a 90° arc when the platform 
is to be moved out of the way. 
The solution:	 How it's done:

pivot slots: Clips on each side of each blade secure it 
to the plate. Each blade slides between two guides, at-
tached to the platform, a distance equal to the length 
of ,the pivot slot, in order to engage or disengage the 
blade toe in the support slots. The blade assembly 
swings up into a vertical position (shown in phantom) 
to clear the adjoining supporting structure when raising 
the platform out of the way. As the platform is lowered 
into place, the blades are lowered into the support 
slots and locked in place by. the blade toes so that 
the supporting plate engages the edge of the supporting 
structure deck to hold the platform in working po-
sition.
