Abstract

Described is a hardware implementation for latching a touchscreen housing onto 12" and 14" Cathode Ray Tube (CRT) monitor bezels. The implementation enables large tolerance variations to exist on the monitor's bezel. The design involves a ball socket/floating insert mechanism which allows a stud to locate and lock into a feature device that may have varying dimensions from a nominal location.

Touchscreen Mount Floating Latch Mechanism

      Described is a hardware implementation for latching a
touchscreen housing onto 12" and 14" Cathode Ray Tube (CRT) monitor
bezels.  The implementation enables large tolerance variations to
exist on the monitor's bezel.  The design involves a ball
socket/floating insert mechanism which allows a stud to locate and
lock into a feature device that may have varying dimensions from a
nominal location.

      Typically, the channels of a monitor will have dimensions which
vary in location to each other as well as from bezel to bezel.  The
tolerance variation on the location may be greater than 3mm.  The
concept described herein provides a means to accommodate large
tolerance variations of monitor bezels so as to provide an efficient
means of attaching touchscreens.

      The touchscreens to be attached to the monitors have four studs
designed to enter a 2mm wide by 7mm deep channel which frames the
front surface of the monitor.  This allows a 90 degree rotation of
each stud to drive a screw thread feature into the wall of the
channel so as to secure the touchscreen to the monitor face.  Each
stud is designed to float in the "XY" direction so as to first locate
the channel and then rotate independent of each other and the touch
screen.

      The design combines a ball socket joint with a floating insert.
The insert is slotted to allow the stud to move in the "Y" direction
and the insert itself slides in a pocke...
