Elastomeric Snap-In Shock With Pneumatic Characteristcs

      Disclosed is a economical elastomeric snap-in shock mount
having pneumatic shock-absorbing characteristics.

      Referring to Figure 1, a shock mount 1 has a bell-shape
configuration open at both ends.  The small opening 2 at the top has
an extended ledge 3 around the opening circumference.  This ledge 3
snaps into a groove 4 provided by anchor screw 5 which anchors a
device 6 to the mount 1. The screw 5 becomes an internal part of the
shock mount 1. On the bottom of the shock mount 1 are two skirt
ledges 7, 8.  The outer ledge 8 is composed of three separate ledges
on the same plane, each having an elongated tapered rib 9. The
tapered rib 9 is used to physically pull each outer ledge 8 through a
corresponding opening 10 (Figure 2) provided in a plate 11.  The
plate 11 serves as the mount platform for the device 6 with shock
mount 1.  As the lower section ledges 8 are pulled through openings
10, the upper ledge 7 is positoned against the top of the plate 11.
The lower ledge 8 is positioned adjacent to the side of the plate 11.
Around the circumference of the shock mount 1 is a compression spring
14.  The spring 14 supports the device 6 during normal operation with
essentially no static forces on the shock mount 1.  When the device 6
undergoes vibration or shock, the mount 1 and spring 14 become
depressed.  Since the interior 15 of the mount 1 is sealed, the mount
1 reacts as a bleeder-type air s...
