Description

The subject of the invention is the improvement of writing instruments for the blind for writing in a conventional (flat) font, with base in the form of a base with a clip for paper and a line with a slot for guiding a writing tip.

Known writing instruments of this type are usually provided with a ruler that does not rise above the base, which creates inconveniences for writing.

In the described device, this disadvantage is eliminated by the fact that for: raising the ruler and turning off the progressive fixing mechanism, it is mounted pivotally on a spring-loaded bar with sockets and has two legs at the end, alternately entering the sockets of the bar and fixing the ruler in its lower position .

The device is intended for the blind, who have lost their sight when they have learned to write.

FIG. 1 depicts a writing device, the appearance; in fig. 2 - section of a ruler with a slot.

On the base 1, made of plastic or other material, a round guide rod 2 is placed, inserted into the holes of the rack 3.

In the upper quarter of the circumference of the rod 2, transverse slits 4 are made at a distance from each other equal in width to two normal rows of standard lined paper. Rod 2 tightly inlet; the head of the ruler J, on which a circle of a handle 6 with two pins 7 is placed; when turning the knob, the pins pull out the stubs of the leg 6 out of the slots.

 81912- About

Moving the ruler along the bar, from line to line, about 1, is shown in the following order.

When the ruler is at the top, on the first line, the upper leg of the spring S is in the upper nest of the rod, and the lower one is on the plane between the sockets, turn the handle so that the upper and tipper lifts it out of the nest, releasing the head from engaging the rod , and move the head with the flykey down; at the same time, the lower leg of the spring, meeting the path of the nest, falls into it and limits the further movement of the ruler, and the upper leg will be on the plane between the sockets. Alternately, freeing from the coupling with the rod, one or the other leg, the ruler is moved to the width of the line.

When the ruler is shuffled, the EPA to its lowest position, it is placed in a vertical position; In this way, the legs of the spring of the heads of the ruler go out of the line of the slots of the rod to a side flat surface, which makes it possible to move the ruler directly up to the initial position, and the irp stacking the ruler on the paper of the upper leg of the rod with the rod through the first slot.

For stacking standard-sized paper in / 2 sheets, there is a recess in the base of the tool, and clamp 9 at the top to secure it at the top.

In the case of an incomplete sheet width, you place the left upper edge of the notch to restrict movement of the arm across the width of the incomplete sheet, and move the limiter // fixed in the slot of the ruler with a screw and nut on the ruler, and move the ruler downwards with a yoke. J2, fastened with a screw on the rod.

You can write with a pencil or pen, and the ink is not smeared when you move the ruler, since there is a gap of 1.5-2 lg between the ruler and paper.

When writing, the hand is superimposed on the edge of the JO. Rule 5 so that the bent little finger moves along the edge of the pole, curved upwards, and the letter must be produced within the boundaries of the longitudinal slit of the ruler. Under the horses, the line, to the right, the hand of the upp-1raet to og |; anichitel //.

To write the letters B, D, and B in figured details up the ruler, with the top edge a few iodates over the paper, and the end of the pencil:; is suitable for the ruler.
