Description

LIGHT AND SOUND DEVICE ASSOCIATED WITH THE USE OF A
ROOM POT FOR YOUNG CHILDREN.

 The present invention relates to the use of everyday objects and utilities for young children, in order to ensure, through play, the learning of certain obligations essential to their education.

 One of the important phases in the field of personal hygiene is the learning of the use of the chamber pot in young children. Also, educators and young mothers, anxious to instill these notions of cleanliness, use psychological ploys that range from persuasion to reward through reprimands, and sometimes this learning is very long.

 Also the present invention proposes to use the taste of the game and more particularly the attraction that arouses any sound or light object in young children, by associating with the classic chamber pot a sound and light device.

 To date, this type of product does not exist on the market, and research in this field has proved negative, only the technological background which consists in associating light or sound devices with certain everyday objects having been identified.

 In the present invention, the means for triggering the melody and the play of light is not produced by placing or depositing the object but by -the creation of a force threshold beyond which the triggering means will act.

 This sanil is exceeded by the weight of the child when he is sitting on the potty. On the other hand, if the pot is placed, normally, on a flat surface without its user, no triggering is likely to occur.

The present invention therefore aims to present a chamber pot associating the utiIitsire side with that of a sound or musical toy and simultaneously luminous by integrating C.Mos electronic circuits of which one of the main advantages is the low energy consumption.
Said invention essentially consists of a melody scheduler controlling simultaneously.

a light chase and a generator of musical frequencies.

 The operation of the device is triggered by bringing the circuits into contact with the current supply produced by cells or batteries.

 The melody programmer is made from an astable multivibrator followed by a decimal counter allowing to obtain binary pulses distributed on four ABC D outputs. Following this count, a BCD / decimal transcoder is connected, in order to cbtir programming signals compatible with the circuits that follow.

 At the output of the circuits described above, the data is directed on the one hand to the input of a light chaser consisting of inverter-s circuits followed by a certain number of light-emitting diodes.

 On the other hand, the programming data, suitably distributed by a battery of diodes and.

nand doors, will control a programmable counter that is part of the musical frequency generator.

 In this musical frequency generator, an astable multivibrator is used, producing the musical note with the highest frequency.

 Knowing that the frequency ratios of the different notes counting the range of an octave are defined according to the high frequency, it is obtained by programmed division the accuracy of the different tones.

 At the output of the programmable counter, a rocker makes it possible to regulate the durations defining the duty cycle of the signals obtained before directing them towards an amplifier and a sound transducer.

In order to explain the invention and to reveal, possibly other new technical characteristics, it is given by way of example, without limitation, an embodiment illustrated by the attached drawings.
FIGURE 1: simplified representation of the device placed under
a chamber pot.

FIGURE 2: Functional diagram of electronic assembly.

 Figure i shows in a simplified way the device placed under a chamber pot (1) in a version comprising the electronic assembly (2) molded on one side connected by a cable (3) to the switch (4) .

 In the molded block (2) there are on the top three light-emitting diodes (5) - placed in the orifices machined in the chamber pot (i) allowing the flushing of said diodes (5) without vacuuming with a tight contact to avoid any possible spillage of liquid there.

 These orifices will advantageously be decorated by the representative. possible of the head of a favorite animal, whose eyes and mouth may blink to the rhythm of the musical melody while following a lighting order of the chase type.

 The molded block (2) consists of main electronic circuits, in (7) the compartment provided with a sealed hatch for the batteries, preferably lithium and in (8) the sound transducer which can be a piezoelectric quartz.

 In a simpler variant, but requiring a new design of the molds for manufacturing the chamber pots, it is possible to integrate into the plastic material constituting these, the entire device by providing translucent zones for the visibility of the diodes. electroluminiscentes.

 Figure 2 is a block diagram describing the main electronic circuits that can be produced in C.Mos technology.

There are three subsets forming this block diagram
the melody programmer (9) generates a programming signal controlling a light chase (10) and simultaneously a generator of musical frequencies (11).

From an astable multivibrator (i2), a decimal counter (13) and one or more NAND gates (i4) are simultaneously activated. The signal from the decimal counter (13) in the form of binary pulses distributed over four outputs A, B, C, D is directed to the input of a BCD / decimal transcoder (15) whose role is to make these signals with the input of a programmable counter (16).

 The data available at the output of the transcoder (15) are also used to control the circuit of the light chaser (íO) by lighting up light-emitting diodes (17) via logic inverters (18).

The program defining the melodious chords is obtained by a battery of diodes and doors
NAND not represented which can constitute a ROM memory.

 To obtain the musical notes constituting the melody, a musical frequency generator (11) is used, the source of which is an astable multivibrator (19) delivering pulses at the frequency of the highest note in the range to be reproduced.

This signal is applied to the input of the programmable counter (16) which is appropriately divided into the report programmed at an instant.
given will send to the rocker (20) a frequency signal at most equal to that of the source (19).

The role of the scale (20) is to regulate the durations
defining the duty cycle of the signals as well as, thanks to the gate (14) the times of rests between certain notes.

 Following this rocker (20) the signal is amplified by the amplifier (21) allowing the excitation of the sound transducer (22) of the piezoelectric quartz type.

 The power supply for the circuits described above is obtained from a battery (23) which can be made up of lithium batteries, the circuit of which closes by the switch (4) located at the base of the chamber pot. .

 This chamber pot for young children can be made to be only bright, or simply sound or in the most complete version as described above it can have sound and light effects.

 The d1Qdes ~ g1ectroduminiscentès can be placed at the discretion of the manufacturer to symbolize eyes and mouth as the example given previously or even have any other provisions adapting to the imagination of the designer.
