Suspension for a pressure sensitive touch display or panel
First Claim
Patent Images
1. A suspension system for mounting a force sensitive touch display or panel having a touch surface defining an x-y plane with a normal z-axis, comprising:
- a frame;
a suspension membrane connected to the touch surface and the frame for suspending the touch surface from the frame, the membrane allowing freedom of movement of the touch surface along the z-axis and resisting movement of the touch surface within the x-y plane; and
at least one force sensor connected beneath the touch surface, whereby the touch surface is pre-loaded against the at least one force sensor.

Abstract
A suspension system for mounting a touch surface of a pressure sensitive touch display or panel. The suspension system comprises a frame and a flexible suspension membrane connected to the touch surface and the frame, the membrane allowing frictionless movement of the touch surface along the z-axis and resisting movement of the touch surface within the x-y plane. At least one force sensor is connected beneath the touch surface, whereby the touch surface is pre-loaded against the at least one force sensor.

10. A suspension system for mounting a force sensitive touch display or panel having a touch surface defining an x-y plane with a normal z-axis, comprising:
-
a frame having a bezel that projects over the touch surface; a suspension membrane connected to the touch surface and the frame for suspending the touch surface from the frame, the membrane allowing freedom of movement of the touch surface along the z-axis and resisting movement of the touch surface within the x-y plane, said membrane being interspaced between the bezel and the touch surface and situate within the periphery of the touch surface, and said bezel applying a downward force to the membrane to pre-load said touch surface; at least one force sensor connected beneath the touch surface, whereby the touch surface is pre-loaded against the at least one force sensor.

11. A touch sensitive display or panel, comprising:
-
a touch surface defining an x-y plane having a z-axis that is normal to the x-y plane; a frame; a suspension membrane connected to the touch surface and the frame for suspending the touch surface from the frame, the membrane allows freedom of movement of the touch surface along the z-axis and resists movement of the touch surface within the x-y plane; and at least one force sensor connected beneath the touch surface, whereby the touch surface is pre-loaded against the at least one force sensor. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A touch sensitive display or panel, comprising:
-
a touch surface defining an x-y plane having a z-axis that is normal to the x-y plane; a frame, the frame comprising a bezel that projects over the touch surface, a suspension membrane connected to the touch surface and the frame for suspending the touch surface from the frame, the membrane allowing freedom of movement of the touch surface along the z-axis and resisting movement of the touch surface within the x-y plane, the membrane being interspaced between the bezel and the touch surface and situate within the periphery of the touch surface on the side that is touched, whereby the bezel applies a downward force to the membrane to create the pre-load on the touch surface, at least one force sensor connected beneath the touch surface, whereby the touch surface is pre-loaded against the at least one force sensor.
