Description

Multiple purpose braille character inserting frame

The utility model belongs to the blind person and uses teaching tool.

The braille word is with a kind of alphabetic writing of blind symbol bundle on cardboard.Because writing of braille need be by means of mould, its Writing method is that reverse side is write, the positive touch read.So just can not arbitrarily write on all places, character-spacing can not be arranged flexibly, and clerical error is difficult to again change, thereby brings very big difficulty for various mathematical operations (vertical as being listed as, establish an equation etc.).And to the beginner of braille be familiar with blind symbol and group speech, many inconvenience are also brought in the sentence-making aspect.

At the above-mentioned braille characteristics and the inconvenience of Braille writing aspect, goal of the invention of the present utility model provide a kind of simple in structure, be convenient to the braille teaching aid that uses flexibly.

The utility model discloses a kind of braille praglit dish of using to achieve these goals, it inserts dish by base plate and the slotting son of character is formed more.Wherein base plate insert bottom surface that dish is provided with vertically and horizontally arranged big or small identical slot be provided with the some position of braille " " 6 jacks one to one, and character is inserted on the two ends of son and is equipped with and the corresponding inserting column of jack position.Be described further below in conjunction with accompanying drawing.

Fig. 1 inserts the structural drawing of dish for base plate;

Fig. 2 inserts the inserting slot construction figure that coils for base plate, and wherein scheming a is the slot front view (FV), and figure b is the A-A cut-open view by figure a;

Fig. 3 inserts sub structural drawing for the flat character, and wherein scheming c is this front elevation of inserting son, and figure d inserts sub vertical view by figure c for this;

Fig. 4 is the structural drawing that son inserted in square character, wherein schemes e and inserts the front elevation of son for this, and figure f is the vertical view by figure e, and figure g is the upward view by figure e;

Insert dish according to base plate shown in Figure 1, vertically and horizontally arranged the identical slot of size, and the number of slot is the amount doesn't matter. Determine the orientation for ease of the slotting son that helps apart from each other, anyhow be provided with protruding crest line every 5 slots on the both direction in slotting panel surface. Insert the slot of dish according to base plate shown in Figure 2, as each slot bottom surface of figure a be provided with braille point "

" 6 jacks one to one, and the distance between adjacent two jacks is R.

Insert son according to flat character shown in Figure 3, the one end has two long inserting columns, and its other end has a long inserting column and a short inserting column, and the distance that reaches between two long inserting columns between a long inserting column and the short inserting column is R, and the height of long inserting column is identical. The flat character is inserted in the jack that can insert dish in sub two ends like this, and the tip of the long inserting column of an end that exposes is exactly the point of braille, and short inserting column plays the assist location effect.

Insert son according to square character shown in Figure 4, its two ends are equipped with the long inserting column identical with the corresponding height of jack position, and the height of the long inserting column of the slotting son of square character is identical with the height of the long inserting column of the slotting son of flat character.As scheme f, and an end of square slotting son is provided with two long inserting columns on its diagonal positions, and its spacing is

As scheme g, and the other end of square slotting son is provided with three long inserting columns, and the distance between its inserting column is that R reaches $\sqrt{2}$ R。Square like this character is inserted in the jack of each slot that can insert letter disk in sub two ends, and the long inserting column tip that an end is exposed is the point of braille.

Provided by the utility model many according to above-mentioned structure with braille praglit dishes, utilize two kinds of different characters insert son on each slot of base plate praglit dish with " " some position is as the criterion, and can insert out 63 kinds of all in the braille blind symbols.Can insert out 13 kinds of blind symbols as inserting son, insert son with two flats and can insert out 23 kinds of blind symbols with a flat.Insert son with three flats and can insert out 38 kinds of blind symbols.As inserting out 12 kinds of blind symbols, can insert out 24 kinds of blind symbols with the slotting son of a flat and a square slotting son with a square slotting son.

This shows that it is many with braille praglit dishes that the utility model provides, its outstanding characteristics be simple in structure, be easy to grasp, the character of inserting out is consistent with braille, and character dial insert flexibly, writing position can arbitrarily arrange, and wrong modification easily occurs.Therefore, utilize many teaching that can promote elementary mathematics with braille praglit dish, as carrying out various mathematical operations with a paper, help the blind child to be familiar with blind symbol, group speech and sentence-making, various simple Weaving patterns, geometric figure can be designed, but also go, Chinese checkers can be done and " Xia Wudao " waits each kind Swam play.

Claims (4)

1, belongs to a kind of the use braille praglit dishes of blind person with teaching tool more, it is characterized in that it inserts dish by base plate and sub the composition inserted in character, wherein base plate is inserted dish and is provided with vertically and horizontally arranged big or small identical slot, each slot bottom surface be provided with the some position of braille "

" 6 jacks one to one, and character is inserted on the two ends of son and is equipped with and the corresponding inserting column of jack position.

2, described many according to claim 1 with braille praglit dishes, it is characterized in that described character inserts son and be flat, and an end is provided with two long inserting columns, the other end is provided with a long inserting column and a short inserting column;
