Braille cell cap
View Patent ↗An electromechanical Braille cell assembly includes a plurality of parallel bimorph reeds. A first plurality of bimorph reeds is mounted to a first side of a printed circuit board by a first plurality of clips and a second plurality of bimorph reeds is mounted to a second side of the printed circuit board by a second plurality of clips. A frame has a top wall, a bottom wall, a first side wall in the form of an angle wall and a second side wall in the form of a flat wall. Pinholes are formed in the angle wall to accommodate Braille pins and the flat wall is slotted to accommodate a plurality of printed circuit boards. A monolithic cap covers all of the Braille pins. Pinholes formed in the cap receive the respective tips of the Braille cells when actuated bimorph reeds cause displacement of the Braille pins.
1. A Braille cell assembly including a plurality of individual Braille cells, the assembly comprising:
a plurality of printed circuit boards, with each printed circuit board controlling the operation of an individual Braille cell;
a plurality of clips interconnected to each of the printed circuit boards, each clip including opposing arms and an intermediate space therebetween;
a plurality of parallel polled bimorph reeds, each reed being positioned within the intermediate space of an individual clip, a plurality of reeds forming an individual Braille cell;
a Braille cell cap positioned over the plurality of Braille cells to enhance tactile feel of the Braille cell assembly by eliminating uneven surfaces.
2. The Braille cell assembly as described in claim 1 wherein the bimorphs include top and bottom plates that are electrically isolated from one another.
3. The Braille cell assembly as described in claim 1 wherein each of the clips is a bimorph clip with horizontal top and bottom walls.
4. The Braille cell assembly as described in claim 1 wherein each printed circuit board includes a series of eight clips and eight bimorphs.
