Description

[Detailed Description of the Invention] This invention relates to a dial auxiliary plate for a push-button dial that allows the numeric positions of the dial buttons of the push-button dial to be easily identified.

Conventionally, the dial buttons of push-button dials used in push-button dial telephones and the like are all configured in the same shape, so it is difficult for even ordinary people, let alone blind people, to distinguish the numbers on the dial buttons in the dark. In such a case, it may be possible to determine the number to some extent by tracing the dial button with a fingertip, but there is a risk that the dial button may be pressed down by mistake during confirmation to make a call. Furthermore, since there is no separating plate between the dial buttons, there is a drawback that people who have sway in their hands due to cerebral palsy or the like may accidentally press adjacent dial buttons at the same time.

This invention solves these shortcomings by
Prepare a dial auxiliary plate, form a partition wall around the standard dial button that is higher than the projection height of the dial button (the amount of protrusion of the dial body from the surface of the dial base (not shown)), and create a partition wall around the other dial buttons. The device forms a low partition so that the reference dial button can be felt, and also prevents adjacent dial buttons from being pressed down at the same time. This invention will be explained below with reference to the drawings.

FIG. 1 shows a push-button dial telephone using an embodiment of this invention, in which 1 is the telephone body, 2 is a handset, 3 is a push-button dial,
It has a dial button 4 displaying numbers "1" to "9" and "0" and a dial button 4 displaying symbols "〓" and "#". 5 is a dial auxiliary plate based on this invention, the details of which are shown in Figures 2a and b.

FIG. 2a is a front view of the dial auxiliary plate 5 of this invention, and FIGS. 2 and 2b are cross-sectional views taken along line A--A in FIG. 2a. The numbers and symbols indicated by dotted lines in Figure 2a are attached to the dial auxiliary plate 5 on the telephone body 1 as shown in Figure 1.
The numbers and symbols displayed on each dial button 4 are shown when the device is attached.

Now, 6 is a board, in which holes 7 correspond to each dial button 4, and each dial button 4 has holes 7 corresponding to each dial button 4.
It is sized so that it can be penetrated. and,
In this embodiment, the hole 7 corresponding to the dial button 4 with the number "5" is used as the reference hole 7, and a partition wall 8 having a height _h1 is formed around the hole 7. As shown in FIG. 2b, the height _h1 is set higher than the height _h0 (the amount of protrusion of the dial body (not shown) from the surface of the dial base) of the dial button 4 (indicated by a dotted line). The height _h2 around the other hole 7
partition walls 9 are formed respectively, and the height h ₂ is lower than the height h ₀ of the dial button 4. Note that if the thickness of the board 6 is set to _h2 , then the hole 7 will be inserted into it.
The lower partition wall 9 can be formed by simply forming.
Then, only the higher partition wall 8 may be formed to protrude above the substrate 6. When the thickness of the substrate 6 is extremely thin, each of the partition walls 8 and 9 may be formed to protrude above the substrate 6. The dial auxiliary plate 5 is configured as described above.

The dial auxiliary plate 5 is attached to the push button dial 3 of the telephone body 1 as shown in FIG. This allows visually impaired people to dial by simply touching the surface of the push button dial 3 with their hand.
The higher bulkhead 8 can be easily identified, and it can be seen that this is the standard dial button 4 (the button with the number "5"). Therefore, the positions of other dial buttons 4 can be easily determined based on this reference dial button 4, which is extremely convenient for selecting a dial number.

In addition, all the dial buttons 4 are provided with a partition wall 8 or 9 around them, so even people whose hands shake due to cerebral palsy, rheumatism, etc. can dial without pressing adjacent dial buttons 4 at the same time. can do.

Note that this dial auxiliary board 5 is attached to the telephone main body 1.
Even if it is left attached to the dial, the parts other than the bulkhead 8 are lower than the dial button 4, so it will hardly interfere with normal use. In addition, the high partition wall 8 is 1
It is not limited to one location, but may be provided at multiple locations.

Further, in the above-described embodiment, the partition wall 8 or 9 is formed around the entire circumference of the dial button 4, but the partition wall 8 or 9 is formed at a position corresponding to the corner of the dial button 4. etc., it is not necessary to form it in some parts. In short, it is sufficient to form it so that the same effect can be obtained.

As explained above, this idea provides a hole in the board through which each dial button passes, a bulkhead that is higher than the height of the dial button around the reference hole, and a wall that is higher than the height of the dial button around the other holes. Since a lower partition wall is provided, the position of the reference dial button can be quickly recognized by touching the higher partition wall, and the positions of other dial buttons can be easily inferred from this. Therefore,
This makes dialing easier even for people who are visually impaired. Also,
Since a partition wall is also provided at the bottom, each dial button is partitioned, which has the advantage that even people with swinging hands can be prevented from pressing adjacent dial buttons at the same time, and dialing can be performed reliably.

[Brief explanation of the drawing]

FIG. 1 shows an embodiment of the dial auxiliary plate of this invention, and is a perspective view of the dial auxiliary plate attached to the telephone body, and FIGS. 2a and 2b are front views of the dial auxiliary plate of FIG. It is a sectional view taken along the A line. In the figure, 1 is a telephone main body, 2 is a handset, 3 is a push button dial, 4 is a dial button, 5 is a dial auxiliary plate, 6 is a substrate, 7 is a hole, and 8 and 9 are partition walls.
