Abstract: Improved alarm clork comprising a clock or watch, time display means, alarm means, means for generating a first number, said number being a random number, means for displaying the random number when the alarm goes off, means for displaying a second number, means for manually modifying said second number and/or said first number, and means for stopping the alarm sound when a predetermined relationship between the first number and the second number is displayed, for example when the first number coincides with the second number.

Description: OBJECT OF THE INVENTION The present invention refers to an improved alarm clock, which is of the electronic type and it has been conceived and embodied as a means to assure the awakening of the user and even the shaking off drowsiness of the user so that once he is awake he does not fall back to sleep. The object of the invention is to provide an alarm clock that can be considered to be reliable, given that some manual operations are necessary so that the alarm stops sounding, there must be light in order to carry out such operations, which ensures the awakening. BACKGROUND OF THE INVENTION Among the numerous types of alarm clocks, one can mention electronically operated ones that include a screen with four digits, two of which indicate the hour and the other two indicate the minutes, in such a way that changing the time and minutes in order to turn on the clock or the alarm of the alarm clock, is done by two push buttons in combination with a four-position switch, one corresponding to the indication of the hour and minutes of the clock; another one corresponding to the indication of the time when the alarm must sound; another one corresponding to the time when the alarm is to be activated and another one corresponding to the time when the alarm is to be deactivated so that it stops sounding. This type of electronic alarm clock that is considered to be a basic one, may prove to be adequate for most people in most situations. Now then, there are exceptional cases in which an alarm clock like the described one may prove to be inadequate to achieve effective awakening of certain people. Thus, the type of people who have difficulty in awakening, who once the alarm has sounded push the corresponding turn-off switch and unknowingly keep sleeping, can be mentioned. On the other hand, there is also the circumstance that on certain occasions the person must be sure that he awakens, such as in the case of having to catch a plane, when an important meeting is to be held early in the morning, etc. It is clear that in these situations and in other similar ones, a system that ensures the awakening of the above mentioned type of people, would be desirable. However no type of alarm clock capable of ensuring the awakening of a certain type of people is known. DESCRIPTION OF THE INVENTION The alarm clock object of the invention ensures the awakening of all those people who have trouble in waking up, and this is achieved by means of an extremely simple but efficient solution. Basically, the alarm clock of the present invention comprises the means enumerated in claim 1 in combination therein. Conveniently, the modification of the first and/or of the second number is done by means of the corresponding push buttons; just as one normally changes the digits of the hour and/or of the minutes when the time shown by the clock or time when the alarm must go off is changed. According to a possible embodiment, it may be necessary to make the first and the second numbers coincide in order to stop the alarm from sounding, that is to say, the system permits the sounding of the alarm to stop when the displayed second and first numbers coincide. The means to display the first number may be functionally associated to the first two digits indicating the hour, in such a way that said digits indicate the first number, while the means to display the second number may be functionally connected with the digits indicating the minutes, in such a way that said digits indicate the second number. In this case, it is advisable that the first number, the random number, is a number from 25 to 99, so that it remains clear that the displayed number does not correspond to the hour, thus avoiding any possibility of confusion. The second number may also be a random number, though it may be practical that said number is a specific number, for example, "00". In this case, it may be especially advantageous that the second number is the number that has to be changed to make it coincide with the first number. The clock of the present invention may include: a screen to display the digits; a general switch with push buttons to allow at least the following operations to be carried out manually: modify the count of the clock means; preset a time at which the alarm must go off; modify the first number and/or the second number; and turn off the alarm when the first and the second numbers coincide on the screen. It may also have a push button to choose between an alarm mode (in which the alarm goes off at a preset time) and an alarm-free mode (in which the alarm does not go off at a preset time). Besides, the clock advantageously includes a push button that permits one to choose between a normal operating mode in which it is not necessary to change the displayed numbers in order to stop the sounding of the alarm, and a special operating mode in which the first random number and the second number are displayed, it being necessary to change at least one of said numbers in order to be able to stop the alarm from sounding. Obviously, there must be light in order to modify the first and/or of the second number and besides the person must be wide awake to do so, since on the contrary, he would be incapable of carrying out the operation. Obviously, this will ensure or guarantee that the person remains awake, since on the contrary, the sound of the alarm will not stop. Hereinafter, to provide a better understanding of this, specification and forming an integral part of the same, some figures in which the object of the invention has been represented in an illustrative and non-restrictive manner, are attached hereto. BRIEF DESCRIPTION OF THE DRAWINGS In order to complete the description that is going to be made hereinafter and for the purpose of providing a better understanding of the characteristics of the invention, a set of drawings based on which one will more easily understand the innovations and advantages of the alarm clock made in accordance with the object of the invention, is attached to the present specification. Figure 1 shows a block diagram corresponding to the clock of the invention. Figure 2 is a front view of a conventional electronic alarm clock. Figure 3 is also a front view of the alarm clock made in accordance with the object of the invention. PREFERRED EMBODIMENT OF THE INVENTION As can be seen in the cited figures, and specifically in figure 1, an electronic alarm clock includes a series of main blocks, starting with a filtering block (1), then a frequency selecting block (2), followed by counters (3), (4) and (5) corresponding to seconds, minutes and hours, respectively, blocks (4) and (5) being related to the corresponding alarm comparator (6) to activate the corresponding alarm circuit (7), including, as usual in an alarm clock, a delay countdown block (8), and the corresponding alarm minute counters (9) and the alarm hour counters (10). Now then, as of the cited block circuit that includes a conventional electronic alarm clock, a generator (11) of a two-digit random number, and a comparator between hours and minutes (12) in connection with the corresponding above mentioned alarm circuit (7) may be included. Now then, once that which is the corresponding general block diagram of the alarm clock of the invention has been cited, this alarm clock physically includes a body (13) with a screen (14) on which two pairs of digits (15-15') and (16-16') appear, the first two digits corresponding to the hours and the second two to the minutes, appearing on the front of the body (13) of the alarm clock push buttons (17) and (18) to change the digits corresponding to the hours and to the minutes. The body of the alarm clock also includes a general switch (19) in which the push buttons (20), (21), (22) and (23) appear, in such a way that actuating the push button (20) allows the indication of the hours and minutes of the clock to be carried out, by actuating buttons (17) and (18). Actuating push button (21) permits the indicating of the time when the alarm must sound. Actuating push button (22) is to leave the alarm activated, while actuating on push button (23) is to eliminate the sound of the alarm, as is shown in figure 1. The cited switches may be push-button, sliding or any other type. Now then, according to a preferred embodiment of the invention a switch (19') that aside from being provided with above mentioned push buttons (20), (21), (22) and (23), includes a new push button (24) in functional association with the random number generating block (11) and with the hours and minutes comparator block (12), in such a way that when activation of the alarm starts, generator (11) simultaneously generates a random number that will appear on digits (15) and (15') corresponding to the hour of the alarm clock, while digits (16) and (16') will indicate "0", is included. The operations must be carried out on the basis of which digits (16) and (16') are made to coincide with digits (15) and (15') generated as random ones by block (11). In order to make that pair of digits coincide, it will be necessary that the person has the alarm clock in front of him, for which purpose he will logically have to turn on the light and then actuating on push button (18) until the first digit of minutes (16) coincides with the first digit of hours (15). Then he must actuate on push button (17) until the second digit of minutes (16') coincides with the second digit of hours (15'), in such a way that once this coincidence between the pairs of digits (15-15') and (16-16') is achieved, the alarm clock will remain in condition to turn off its alarm, by means of actuating on the corresponding push button (23).
