Abstract

(57) [Summary] [Purpose] Since the metal braille pin is directly driven into the fixed surface, no adhesive is required, resulting in good work efficiency and a beautifully finished surface. The caulking projections on the shaft bite into the braille holes and firmly bond. [Structure] A Braille display in which a metal Braille pin 3 having a sharp shaft end is driven into a Braille hole 2 formed in a fixed surface 1, and a caulking protrusion 6 is formed on a shaft portion 4 of the Braille pin 3 to form a Braille mark. The hole 2 and the shaft portion 4 are directly fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a Braille display formed by directly driving a Braille pin on a fixed surface such as a side wall, a pillar, or a device.

[0002]

[Prior art]

 Braille display is widely used for walking safety, guidance to the destination, device operation, etc., but in the conventional braille display, whether a convex part to be braille is stamped on the surface of the metal plate, is it formed? Almost all of them are made of synthetic resin thin plates and have braille characters bulged. The plates are attached to the fixed surfaces such as side walls with an adhesive or fixed with screws. Braille display made of a metal plate is relatively large when printed with braille, so it is difficult to read when touched by hand. At the same time, there is a drawback that dirt adheres during long-term use and damages the appearance.

Therefore, unlike these techniques, a technique has been proposed in which a hole is formed at a place where Braille is to be installed, and a pin having a head is inserted and fixed in the hole (for example, Japanese Utility Model Laid-Open No. 2-42698). reference).

[0004]

[Problems to be solved by the device]

 In the technology using this pin, the hole diameter must be made larger than the pin, and in order to fix the pin with the adhesive, it is necessary to work so that the adhesive does not flow out, and There was a problem that the adhesive strength weakened and the pins wobble or escape if the environment changes due to insufficient temperature or temperature rise.

In the present invention, there is no risk that the surface of the Braille will be peeled off or crushed by directly driving the Braille pin to the fixed surface, and since the adhesive is not used, the work is carried out quickly, and the temperature rises. It is also intended to provide a braille display that can be permanently fixed without being affected.

[0006]

[Means for Solving the Problems]

 Therefore, in the braille display of the present invention, a braille hole is vertically formed on a fixed surface such as a side wall, and a metal braille pin having a sharp shaft end is driven into the braille hole, and the braille pin shaft is provided. This is characterized in that a caulking projection is formed on the portion, the shaft portion is directly fixed to the Braille hole, and the Braille pin head portion is uniformly projected on the surface of the fixed surface.

[0007]

[Action]

 Since the braille pin is directly driven into the braille hole, it is firmly fixed in the correct position.Because the braille pin is made of metal, there is no risk of the head being crushed. Because it is done, it firmly connects with the Braille hole. Furthermore, since the braille pin on the fixing surface of the braille pin is vertical, the fixation is not uneven and there is no risk of misreading.

[0008]

【Example】

 In Fig. 1, 1 is a fixed surface such as a corridor / interior side wall, and on the upper part of the handrail T that is laid horizontally on the lower part of the wall, use the braille pin 3 made of stainless metal to make a line saying "Be careful with your foot." The markings are displayed on the fixed surface 1 in parallel with the braille pins 3 and the normal markings are written on the fixed surface 1 "Be careful of your feet."

FIG. 2 shows a state in which the Braille pin 3 is driven into the Braille hole 2 formed in the fixed surface 1, and FIG. 3 shows a state in which the Braille pin 3 is fixed to the fixed surface. The braille hole 2 is formed with a 1 mm diameter drill so as to be perpendicular to the fixed surface. Before performing the drilling work, attach a braille document to the fixed surface 1 and set the positioning points in advance. deep.

The Braille pin 3 has a sharp end portion of the shaft portion 4 and has a shaft diameter of about 1 mm, which is not larger than that of the Braille hole 2 and has a total length of 10 mm and a head diameter of The thickness of the head portion 5 protruding from the fixed surface 1 at 1.3 mm is about 0.7 mm. A caulking projection 6 is formed on the shaft portion near the head.

As shown in FIG. 2, when the head end 5 is hit with a hammer while applying the shaft end of the Braille pin 3 toward the Braille hole 2, a caulking projection 6 formed near the head bites into the Braille hole 2. The Braille pin 3 is fixed and becomes integral with the fixing surface as shown in FIG.

FIG. 4 shows an example of use in which the Braille pins 3 are vertically inserted into the spherical fixed surface 1, so that the Braille pins 3 are arranged radially from the center of the fixed surface 1. In this case as well, the pin head 5 is in a uniform protruding state.

The fixing surface 1 may be the side wall itself or a separate plate material installed inside the side wall, and the material shape is not limited to that of the embodiment. Further, in the present invention, the fixing surface is a new one or an existing one. It does not matter whether or not it is, and the display of characters is an optional matter, and when provided, it attracts the attention of healthy persons, but it is not always necessary.

[0014]

[Effect of device]

 The present invention as described above has the following unique effects. (1) Since the Braille pin is directly driven into the fixing surface, there is no need to use an adhesive, and there is no room for contamination due to leakage of the adhesive. In addition, the Braille pin retains a strong fixed state regardless of temperature rise. (2) It does not require extra material such as adhesive, so it can be provided at a low price, and if the Braille pin is driven into the Braille hole, the installation is completed, so easy and quick work can be done and fixed. The surface is also beautifully finished. (3) Since the shaft portion is formed with the caulking protrusion, the protrusion bites into the Braille hole, so that the fixed state is further strengthened, and the Braille pin does not loosen or come out under any shock. (4) Since it is suitable for on-site work, it can be easily installed on existing fixed surfaces and can be applied to a wide range of facilities.
