DE3106656A1 - Clock/watch for blind people - Google Patents

Abstract

A clock/watch for blind people is proposed, which has retractable and extendable buttons (2, 3, 4, 5), which is intended to make it possible for blind people to detect time values, accurate to the minute. In accordance with the principle of set theory, the buttons are arranged into groups each having a certain time value, and are controlled by the clock/watch-work. Moreover, the clock/watch for blind people can be equipped with an acoustic signal transmitter (10) and an alarm, and, in addition, can be provided with a release button (7), an alarm-setting button (8) and a time-resetting button (9). The clock/watch for blind people can, inter alia, take the form of a wristwatch (1). <IMAGE>

Description

description

The invention relates to a blind watch with specific time intervals associated tactile elements.

Conventional blind watches are both hands and on the outside Edge of a dial circularly arranged bumps, which a certain Time are assigned, palpable. These clocks have the disadvantage that they are accurate to the minute Time recording is not possible. Rather, the minutes must be emotionally interpolated will. The main disadvantage of such blind watches is that the reading system is not typical of the blind. This can be seen in the fact that, for example, during development Braille did not use tactile letters of the alphabet but that new tactile systems are being developed Has, which the blind person can learn and reproduce more easily.

The object of the invention is to create a clock that blind people the "reading" of the time facilitates and also the reading of small time units, like minutes, allows.

This object is achieved according to the invention by a blind watch controlled by the clockwork, each assigned to a specific time interval, and retractable buttons.

Conventional motorized or electronic drives are used as clockworks Clockworks into consideration.

The blind watch according to the invention preferably has different ones Groups with retractable and retractable buttons. The blind man can feel with his hand whether the buttons are in the retracted or extended state. Are there the individual keys of a group are each assigned to a specific time interval. After this time interval has elapsed, the respective key is extended, whereby the Keys that were extended earlier remain in the extended state. After this the last key in a group for the duration of the time interval assigned to it is extended, all keys in this group are deleted, i. H. retracted again. At the same time, a key of the next higher group is then extended.

The clock according to the invention adopts the principle of set theory Use. A clock working according to this principle is already from DE-OS 23 39 482 known. However, the clock specified there is for blind people unsuitable as it only provides optical values via an illuminated display. -It is that Special merit of the invention to have recognized that with the principle of Set theory an easy and safe to use watch, especially for blind people can be realized.

An unlocking button is preferably provided on the clock, according to whose actuation all keys are extended. The clock is then pressed by pressing the corresponding buttons. The resulting display is displayed by pressing an adjustment knob held. The adjustment knob is preferably protected on the back of the watch so that it cannot be operated unintentionally.

According to a preferred embodiment, the blind watch has a built-in alarm clock. To operate it, first use the release button all buttons extended. After setting the desired alarm time manually the resulting display is saved by pressing an alarm button. To If you press a time reset button, the watch will display the desired time again. if the stored time is reached, an acoustic signal generator is activated, the emits an acoustic signal. The saved alarm time can be used for control purposes can be displayed again by pressing the alarm button.

The blind watch according to the invention can also be designed so that when certain or all buttons are extended by the acoustic signal generator a signal is given.

A preferred embodiment of the invention is illustrated below the drawing explained. They show: FIG. 1 a watch for the blind in the form of a wrist watch in plan view; FIG. 2 shows the object according to FIG. 1 in section along the line II-II and FIG. 3 the object according to FIG. 1 in section along the line II-IIt.

There are four on the front of a clock designed as a wristwatch 1 different groups of buttons 2, 3, 4, 5 assigned, which are in the extended state represent protruding, palpable elevations while in the retracted state do not protrude beyond the surface of the watch.

The four buttons 2 in the top row each correspond to one Time interval of five hours. The four buttons 3 correspond in the second row each with a time interval of one hour. The eleven keys 4 in the third row are each assigned time intervals of five minutes, while the four buttons 5 in the bottom row each assigned to a time interval of one minute are.

The buttons 2, 3, 4 and 5 are functionally linked to the movement in such a way that that the keys of each group are extended one after the other, with already extended keys remain extended. Only after the last key a group is extended for the duration of the time period assigned to it all buttons in this group are deleted. At the same time, a key becomes the next higher Group extended.

In FIG. 1, the extended state of the keys is indicated by double hatching marked while the single hatched keys are retracted, d. H. are not palpable as elevations.

The time shown in Figure 1 is composed as follows: 3 x 5 h = 15 h 2x1h = 2h 2 x 5 min = 10 min 1 x 1 min = 1 min Specified time = 17 h 11 min When the clock is set for the first time or

if it is readjusted, a release button 7 all buttons 2, 3, 4 and 5 extended. Then the clock is set by hand; d. H. all buttons that must not be palpable for the time to be set become depressed. The resulting display is displayed by pressing an adjustment button 6 recorded. The adjustment button 6 is preferably protected on the rear side the clock, so that unintentional operation is impossible.

Of course, the buttons can also be arranged in a different form as long as a principle corresponding to set theory is adhered to. So can change the number of buttons in each group, the number of groups themselves and the spatial arrangement and division of the keys or

of the individual groups can be varied.

Unless, for example, a minute reading is not a large one Value can be added to the first two groups shown in the figure of buttons 2, 3 only a third further group with five buttons can be provided, in the third group each key corresponds to a time interval of ten minutes. In this way, a reading accuracy of ten minutes is guaranteed. The reading accuracy The latter embodiment can be increased by adding one of four Keys existing fourth group is provided, each key being this last Group corresponds to a time interval of two minutes. The reading exercise is in this case two minutes.

The blind watch according to the invention can also be provided with a clock be. To set the alarm clock, all by means of the release button 7 Keys 2, 3, 4, 5 extended. Then the desired wake-up time is set manually, d. H. all buttons that must not be palpable for the time to be set become depressed.

The resulting display is activated by pressing an alarm button 8 saved. After pressing a time reset button 9, the watch reverts to normal Time on. When the specified time is reached, an acoustic signal is emitted 10 actuated. The saved alarm time can be checked by pressing the Alarm button 8 can be displayed again.

The blind watch according to the invention can also be designed so that the acoustic .Signalgeber 10 when extending certain or all keys Lets the signal sound. This has the advantage that the haptic information is supplemented by acoustic information.

Of course, the measures explained above can be used for the most varied of clocks, such as pocket watches, grandfather clocks.

Wall clocks o. The like. Realized.
