Tactile relief display device and method for manufacture it
First Claim
Patent Images
1. An electromechanical relief display device comprising:
- a frame;
at least one tactile member provided in said frame which is movable between a first position and a second position such that by feeling for said tactile member a user determines in which position said tactile member is;
an oblong piezoelectric flexion member which may be bent under the influence of voltages applied thereto; and
a supporting means for supporting said flexion member on said frame at two separate locations such that a third separate location of said flexion member is coupled to said tactile member to move said tactile member between the two positions as said flexion member is bent, said third separate location being to one side of said first and second separate locations along said fixation member.

Abstract
A braille cell having piezoelectric reeds (8-11) attached at one end (28), supported in their middle region (at 29) and cooperating with tactile members (12-15) at their other end. The attachment of the reeds at their one end (28) being by soldering a protruding part of the reeds to a conducting web (32) parallel to the flexion plane of the reeds. The other ends of the reeds are then located in the desired position with respect to the tactile members.
