Abstract

A variable contour securing system has a retaining structure for a member whose surface contains a variable contour. The retaining mechanism includes a spaced array of adjustable spindles mounted on a housing. Each spindle has a base member support cup at one end thereof. A vacuum source is applied to the cups for seating the member adjacent to the cups. A locking mechanism sets the spindles in a predetermined position once the member has been secured to the spindle support cups.

Claims

1. A variable contour securing system including:

means for retaining a member at a surface having a variable contour comprising a spaced array of adjustable spindles mounted on a housing base member having supporting cups at one end thereof;

means for providing a vacuum source to said cups for seating said member adjacent to said cups; and

reference spindles being provided which are fixedly secured to said housing base.

2. A variable contour securing system in accordance with claim 1 wherein said adjustable spindles are formed of hollow cylinders whose interior surface forms a path for air flow from said cups to said vacuum source.

3. A variable contour securing system in accordance with claim 2 wherein said adjustable spindles are vertically movable along the axis of said cylinders.

4. A variable contour securing system in accordance with claim 3 wherein said adjustable spindles are spring biased along the axis of said cylinders.

5. A variable contour securing system in accordance with claim 3 and further comprising locking means for setting said adjustable spindles in a predetermined position when said member is secured to said spindle cups.

6. A variable contour securing system in accordance with claim 5 wherein said locking means comprises a locking piston associated with said spindles and a flexible bladder adjacent to said locking piston, movement of said bladder causing a force to be applied to said locking pistons for retaining said spindles in said predetermined position.

7. A variable contour securing system including means for retaining a member at a surface having a varible contour comprising a spaced array of adjustable spindles mounted on a housing base member having supporting cups at one end thereof, said adjustable spindles being formed of hollow cylinders whose interior surface forms a path for air flow from said cups to said vacuum source, and said adjustable spindles being spring biased along the axis of said cylinders and vertically movable along the axis of said cylinders;

locking means for setting said adjustable spindles in a predetermined position when said member is secured to said spindle cups, said locking means comprising a locking piston associated with said spindles and a flexible bladder adjacent to said locking piston, movement of said bladder causing a force to be applied to said locking pistons for retaining said spindles in said predetermined position, and

a source of air being provided for positioning said bladder adjacent said locking pistons.
