Abstract

The utility model relates to a mapper for blind men, which comprises a drawing board and a drawing pen, wherein the drawing board is provided with salient points which have the same size and are provided orderly with equal distance on a bottom board. The marginal parts of the outer side, the upper part, the lower part, the left and the right of each salient point are respectively provided with a rib that is convex upwards. The nib of the drawing pen is a fork-shaped body with a concave surface and two fork ends of the nib are smooth cambered surface. The utility model uses the salient points at the front side to draw on the face, so the braille paper does not need to be reversed in drawing, and the device can draw on the front side and recognize the drawing which is quite distinct and is easy to label numbers and letters. The utility model saves time and is easy to operate.

Description

Mapper for bindman

Technical field

The utility model relates to the plotter that a kind of blind person uses, especially can the positive Mapper for bindman of knowing figure.

Background technology

At present, it is that braille paper is layered on the rubber slab mostly that the blind person draws, and with the braille nib firmly delineation drawing downwards of writing, utilizes the cut of braille paper back side projection to touch the interpreting blueprints sample then.This drawing practice has following deficiency: 1, drawing with know figure not at same paper, and drawing is opposite with knowledge figure direction, is unfavorable for that human thinking and the coordination of starting to chart carry out; 2, the pattern projection is not obvious, discerns unintelligible; 3, need ceaselessly reverse in drawing course braille paper identification and delineation have caused the trouble of waste of time and operation: 4, can't reference numbers and letter.

Summary of the invention

In order to overcome the deficiency of existing blind person's plotting equipment, the utility model provides a kind of Mapper for bindman, and this Mapper for bindman not only can positively be drawn, and can also positively know figure, and easy to operate, is very easy to when reference numbers and letter.

The technical scheme that its technical problem that solves the utility model adopts is: this Mapper for bindman comprises drawing board and drawing pen two parts, described drawing board is to be provided with the salient point that proper alignment, identical, the spacing of size equate on base plate, and the outer ledge part of the salient point on base plate respectively is provided with a rib that raises up.The nib of described drawing pen is the fork with inner concave, and the end of two forks is slick and sly cambered surface.

For ease of using, described salient point is the hemispherical body of radius 0.4mm-0.6mm; Described rib is the semicylinder of radius 0.4mm-0.6mm.

Above-mentioned base plate can be plastic plate or metallic plate; Gap between salient point is 0.9mm-1.1mm; The forked inner concave of nib is advisable with the salient point that can contain on the base plate, and nib is that metal material is made, and pen is as flat, and flat horizontal surface is consistent with nib fork face, so that identification nib prong.

The beneficial effects of the utility model are: because the utility model adopts salient point positive projection in front to draw, need not the braille paper that reverses in drawing course, can positively draw, know figure, pattern is clear, is easy to reference numbers and letter, saves time, easy to operate.Through to the utility model test shows, use this Mapper for bindman answer mathematics geometric figure topic, more existing blind person's plotting equipment is compared, and can save time more than 3 times.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the front view of the used drawing pen of the utility model.

The specific embodiment

As shown in Figure 1, on base plate 6, be provided with proper alignment, identical, the spacing of size and equate the salient point 1 that raises up, this salient point 1 is the hemispherical body of radius 0.4mm-0.6mm, gap between salient point is 0.9mm-1.1mm, each salient point is at horizontal cross and vertical vertical and oblique different directions, all can constitute straight line, be the center of circle with certain salient point, also can constitute near round shape; The outside of the salient point 1 on base plate 6, the marginal portion respectively is provided with a rib that raises up 2 up and down, and this rib 2 is the semicylinder of radius 0.4mm-0.6mm.Above-mentioned base plate 6 can be plastic plate or metallic plate.

As shown in Figure 2, the nib 3 of described drawing pen is for having the fork of inner concave, and two fork end of nib 3 are slick and sly cambered surface.The forked inner concave of nib 3 is advisable with the salient point that can contain on the base plate, and nib 3 is made for metal material, and a body 4 is a flat, and flat horizontal surface is consistent with nib fork face, so that identification nib 3 prongs, the end of a body 4 is the cap for brush 5.

During drawing, earlier braille paper is fixed on the base plate 6, then by the blind person with drawing instruments such as rulers, on braille paper, delineate drawing with described drawing pen, as if need straight line real segment, can directly braille paper be placed on the rib 2, delineate with drawing pen; During delineation with a body support with favored policy, and firmly hold a body, the paddling of uniform and stable, make hand that significantly pause and transition in rhythm or melody sense up and down be arranged, just can on braille paper, obtain the tangible line segment of salient point, when reference numbers or letter, can be in the position that will mark, pin salient point with drawing pen, Rotate 180 ° can obtain the braille point of projection on braille paper; In addition, if this drawing pen nib partly is installed on the bipod of existing compasses, can also draw circular pattern.

Claims

1, a kind of Mapper for bindman, comprise drawing board and drawing pen, it is characterized in that described drawing board is to be provided with the salient point (1) that proper alignment, identical, the spacing of size equate on base plate (6), the outer ledge part of the salient point (1) on base plate (6) respectively is provided with a rib that raises up (2); The nib of described drawing pen (3) is for having the fork of inner concave, and the end of two forks is slick and sly cambered surface.

2, Mapper for bindman according to claim 1 is characterized in that described salient point (1) is the hemispherical body of radius 0.4mm-0.6mm.

3, Mapper for bindman according to claim 1 is characterized in that described rib (2) is the semicylinder of radius 0.4mm-0.6mm.
