Definitions

  • This invention relates to a braille writer and more particularly to a mechanical braille writer with an improved embossing mechanism.
  • the braille writer of the invention includes a chassis supporting a plurality of finger operated keys with each key mechanically interconnected with an embossing mechanism so that depression of a key causes a corresponding one of a plurality of pins in the embossing mechanism to extend outwardly from the embossing mechanism to create a raised dot on paper adjacent to the embossing mechanism.
  • the embossing mechanism includes a block adapted for slidingly guiding the plurality of pins for paper contact. Each one of the plurality of pins is straight and substantially identical to the other pins.
  • margin guides are mounted at the front of the chassis and paper advance knobs are wingnut- shaped.
  • the braille writer of the invention is significantly lighter in weight than the previous Perkins braille writer.
  • the present braille writer is more ergonomically refined and is less expensive to manufacture and assemble.
  • Fig. 1 is a perspective view of a prior art Perkins braille writer.
  • Fig. 2 is an exploded, perspective view of the prior art embossing mechanism used in the braille writer of Fig. 1.
  • Fig. 3 is a perspective view of the braille writer according to an embodiment of the invention.
  • Fig. 4 is a perspective, rear view of an embodiment of the invention disclosed herein.
  • Fig. 5 is an exploded, perspective view of the embossing mechanism according to an embodiment of the invention.
  • Fig. 6 is a perspective view, with cover removed, of an embodiment of the invention disclosed herein.
  • Fig.7 is a plan view, with cover removed, of the embodiment of the invention shown in Fig. 6.
  • Fig. 8 is a bottom view of the embodiment of the invention shown in Fig. 7.
  • a prior art mechanical braille writer 10 includes six keys 12-22 each one of which controls an embossing pin for making raised dots on paper.
  • a spacer bar 24 creates a space in a line of braille code.
  • a line spacer 26 and a back spacer 28 are also provided along with a handle 30.
  • Paper is controlled by a paper feed knob 32 and a paper release 34.
  • a carriage return lever 36 is provided to return an embossing mechanism to the beginning of a line.
  • the mechanical braille writer 10 includes a movable embossing mechanism or carriage assembly that is shown in Fig. 2.
  • This prior art embossing mechanism 40 includes six pins 42-52 each mounted in its own block. As can be seen in Fig. 2, the pins 42-52 are not straight and differ from one another. Because the pins 42- 52 have different shapes, hand finishing is required for making the assembly. The pin design also requires careful adjustment and tuning during the assembly process. Those of ordinary skill in the art will appreciate that when one of the keys 12-22 is depressed, a corresponding one of the pins 42-52 will extend and create a raised dot in paper (not shown) in the braille writer 10.
  • an embodiment 60 of the new Perkins braille writer includes embossing keys 62-72, a line spacing key 74 and a back space key 76.
  • margin guides 78 and 80 are at the front of the braille writer 60 rather than in the back as is the case with the prior art braille writer shown in Fig. 1.
  • This embodiment also includes paper advance knobs 82 and 84 that have a "wingnut” configuration for ease of gripping.
  • This embodiment also includes paper release levers 86 and 88.
  • This embodiment also includes an embossing mechanism or carriage assembly 90.
  • a front portion 91 (Fig. 3) of the braille writer 60 serves as an integrated handle.
  • a moveable panel 93 serves an integrated paper tray, reading rest and alignment surface.
  • Fig. 7 shows a paper drum assembly.
  • the embossing mechanism or carriage assembly 90 will now be described in more detail in conjunction with Fig. 5.
  • the mechanism 90 includes an array of six pins 92 that are slidingly guided by structure 94. Note that the pins in the array of pins 92 are straight and identical to one another. In contrast to the prior art pins 42-52 shown in Fig. 2 that have differing, non-straight shapes, the straight pins 92 in the present embodiment are much easier to assemble and adjust.
  • a button 100 may be pushed downwardly onto a beam 102.
  • the beam 102 then lifts a cell spacer assembly 104 by means of a hooked wire 106.
  • pushing the button 100 results in the lifting of the cell spacer assembly 104 away from the rack bar thereby releasing the carriage.
  • a user depresses one of the embossing keys 62-72 that causes a corresponding one of the pins in the array 92 to extend so as to emboss a raised dot on paper (not shown) passing between surfaces of the embossing mechanism 90.
  • the user activates a spacebar 92 to prepare for embossing a next letter.
  • Figs. 6, 7, and 8 are cutaways of the braille writer disclosed herein showing the mechanical interconnections that enable embossing.
  • the braille writer 60 disclosed herein is significantly lighter than its predecessor.
  • the new braille writer 60 is also more ergonomically accommodating in that the margin guides 78 and 80 are on the front of the machine. It is also much easier and less expensive to assemble because of the unique carriage or embossing mechanism disclosed herein.

Abstract

L'invention porte sur un dispositif d'écriture Braille mécanique qui comprend un châssis portant une pluralité de touches actionnées par les doigts, chaque touche étant mécaniquement interconnectée à un mécanisme de gaufrage, de telle sorte que l'enfoncement d'une touche provoque l'extension vers l'extérieur du mécanisme de gaufrage d'une broche correspondante parmi une pluralité de broches dans le mécanisme de gaufrage de façon à créer un point surélevé sur un papier adjacent au mécanisme de gaufrage. Le mécanisme de gaufrage comporte un bloc conçu pour guider en coulissement la pluralité de broches pour un contact avec le papier. Il est préféré que chacune de la pluralité de broches soit droite et identique aux autres broches.
