Abstract

Disclosed is a polymer clamping device which pivots to allow removal and installation of the clamped workpiece. Polymer beams deflect in two orthogonal directions; one direction to engage latching means and the second direction to apply a clamping load while in the working position. The mating plastic part provides simple pivot and latching points.

Polymer Clamping Device

       Disclosed is a polymer clamping device which pivots to
allow removal and installation of the clamped workpiece.  Polymer
beams deflect in two orthogonal directions; one direction to engage
latching means and the second direction to apply a clamping load
while in the working position.  The mating plastic part provides
simple pivot and latching points.

      Fig. 1 is an isometric view of the polymer clamping device.
Shown in the figure are the pivot points 1 and the deflecting beams
2.

      Fig. 2 illustrates the clamping position of the device. The
mating plastic frame 3 provides simple pivot points 4 and deflection
points 5 for the clamp.  In this view, the clamp rotates clockwise to
clamp the workpiece 6 and counterclockwise to unclamp.  The beams 7
are deflected clockwise by the frame ribs at the deflection points 5
to supply the clamping load 8 to the workpiece 6.

      Fig. 3 illustrates the latching technique of the device.
During clamping or unclamping of the workpiece 12, beam deflection 9
takes place when the clamp 12 is rotated between the frame ribs 11.
The clamp is latched in the clamping position (Fig. 2) when the beams
return to the undeflected state 10 where the frame ribs 11 latch the
clamp.
