Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a braille for writing Braille for the blind. A braille device for writing Braille is composed of a board, a ruler, and a writing brush, and the present invention relates to an improvement of this writing brush.

[Conventional technology]

Conventionally, a braille for writing Braille is fixed by embedding a core rod made of iron or stainless steel with a uniform thickness from the tip to the root into a spherical or cylindrical or spindle-shaped grip body made of wood or synthetic resin. The structure was

[Problems of conventional technology]

However, conventional brushstrokes have a uniform thickness from the tip that directly presses against the paper to the end that is embedded in the grip body, so the grip body of the core stick is in use. There was a case where a load was applied to the base part of and and it was deformed.

In addition, since writing Braille generally creates unevenness on the paper,
It is necessary to apply a considerable amount of force to the brush,
It was a very labor-intensive job. Conventional braille brushes have a center of gravity in the grip, and the core rod only projects with a certain thickness.Because a force is required at the tip of the core rod, writing Braille is poor in workability and efficient. Didn't improve.

[Means for Solving Problems] The present invention has been made in view of the above, and improves the durability of the brush itself, and even when writing Braille, the hand is less likely to get tired and the writing efficiency is high. The purpose is to provide a brush.

That is, according to the present invention, in a Braille brush formed by integrally mounting and fixing a core rod and a grip portion main body, the core rod and the grip portion are attached in a taper shape from the core rod to the grip portion tip protruding portion. That is, that is, the end portion of the core rod of a certain length is tapered in the grip body direction, and the embedded portion of the core rod is provided at the center of the thickened portion. The thickened part was adhesively fixed to the grip body of the same diameter.

〔Example〕

An embodiment of the present invention will be described. Reference numeral 1 is a grip body made of wood or synthetic resin, and the body 1 is composed of a protruding portion 2 partially protruding in a taper shape and a knob portion 3 having a knob shape. ing. A core rod 4 is fixed to the tip of the protruding portion 2 of the main body 1. The core rod 4 has a tip portion made of stainless steel or nickel-plated iron having a certain standard diameter, and has a certain thickness. After being formed to a required length, it is formed in a taper shape in the grip portion main body direction so as to match the taper of the protruding portion 2, and the embedded portion 5 protrudes in the central portion.
The core rod 4 is provided with a hole at the tip of the protruding portion 2 of the grip body 1, and the embedded portion 5 of the core rod 4 is embedded in the hole to firmly fix the core rod 4.

As described above, the tip of the core rod 4 is formed in a rod shape having a specified diameter, and the tip is slightly rounded. Therefore, the tip of the core rod is inserted into the recess of the plate, and the paper is pressed into contact with the unevenness. Are formed so that they can be fitted together conveniently.

[Effect of device]

According to the present invention, however, since the mounting portion between the core rod 4 and the grip portion 1 is thickened in a taper shape from the core rod 4 to the grip portion 1, the strength of the core rod main body mounting portion is increased and the durability of the brush is improved. It improves the sex. Also, since the core rod becomes thicker and the center of gravity of the brush itself goes down, and the joint between the core rod and the protruding part of the grip body is thickened, a constricted part is formed between the knob and
The fingers enter this part moderately, and this reduces the fatigue of the hand when grasping the brush, which is of great practical value.
