CH TIMER ALARM AUTOMATIC ALARM SYSTEM FOR BATHROOM BACKGROUND OF THE INVENTION It is not uncommon today to find many people living alone such as in rural communities and even in metropolitan areas in large apartment complexes and the I like. While many of such persons living alone are relatively young, a large proportion of such persons are elderly and therefore subject to debilitating or incapacitating attacks such as seizures, comas and the like during which they are unable to summon help. Furthermore, both young and old alike are subject to injury rendering them unable to call for assistance and, of course, criminal assaults may produce injuries which may render such persons unconscious or place them in such a weakened condition that a call for assistance is not possible. It can be easily seen that failure to obtain medical assistance or other help can easily result in aggravation of the injury and even death if such assistance is not forthcoming. In addition, many people living alone today have little contact with the outside world and it is not uncommon for days to pass before any notice is taken of inactivity on the part of a person who is physically incapacitated.
It has been proposed to provide persons living alone and particularly elderly persons who might be incapacitated with various devices worn on the portions of the body such as on the wrist which respond to immobility and trigger an alarm. Such devices are not only complicated and expensive but when removed such as for bathing are frequently not replaced on the wearers body due to forgetfulness defeating their purpose. Furthermore, such devices are easily damaged and require periodic maintenance.
SUMMARY OF THE INVENTION Accordingly, a primary object of this invention is to provide a new and novel automatic alarm system for protecting a person who is unable to summon help.
Another object of this invention is to provide a new and novel alarm system which is automatically actuated when a person becomes incapacitated for a predetermined period of time.
A further object of this invention is to provide a new and novel automatic alarm system for an incapacitated person which does not require the wearing of any device by the person and which does not require any conscious thought on the part of the person to maintain the system in operation.
This invention further'contemplates a provision of a new and novel automatic alarm system which utilizes a minimum of component parts, which is simple and inexpensive in construction and which is maintained in operation by reliance on a normal regular body function.
Still another object of this invention is to provide a new and novel automatic alarm system for summoning help for a person who becomes suddenly unable to call for assistance and which is particularly adapted for use by elderly persons living alone to reduce or eliminate additional medical complications and to relieve such persons of mental anguish associated with the poor health in a critical situation.
Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawing.
In general, the object of this invention and other related objects are accomplished by the provision of an alarm system arranged to be associated with a conventional flush-type commode having an actuating arm pivotally movable between an inoperative position and an operative position for flushing the commode. The system includes a timer having resettable means and arranged to be preset to a selected time cycle together with alarm means and means controlled by the timer for actuating the alarmmeans upon termination of the time cycle. Means operatively associated with the commode actuating arm are provided for actuating the timer resetting means to. reset the time cycle upon each pivotal movement of the actuating arm into the operative position during the flushing of the commode.
BRIEF DESCRIPTION OF THE DRAWINGS The novel features which are believed to be characteristic of the invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation may be best understood by reference to the following description taken in conjunction with the accompanying drawing in which:
FIG. I is a perspective view of the automatic alarm system of the invention in the installed condition;
FIG. 2 is a fragmentary perspective view of a portion of the invention of FIG. 1 showing the parts in an inoperative position;
FIG. 3 is a view similar to FIG. 2 showing the parts in an operative position; and
FIG. 4 is a block diagram illustrating the interconnection, of the component parts of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIG. 1, there is shown the alarm system of the invention in an installed position such as in the bathroom of a typical residential structure. The alarm system of the invention is arranged in association with a conventional flush-type commode designated generally by the letter C, which includes a tank 1 I having a removable cover 1 la and a manually operated actuating arm 12. As is well known, the actuating arm 12 is pivotally mounted on the water tank 1 I and includes an operating handle 13 at one end projecting outwardly from the tank 11 for manual manipulation by an individual. A linkage 14 having a valve (not shown) is attached to the other end of the actuating arm 12, the valve being arranged to seat in the tank water outlet in the inoperative positon of the arm 12 as shown in FIG. 2 in the well-known manner. Thus, when the handle 13 is manually moved in the direction of the arrow I, the actuating arm 12 is moved pivotally upward in the direction of the arrow P into the operative position of FIG. 3 lifting the valve through the linkage '14 and permitting water in the tank 11 to pass through the outlet flushing the commode.
As specifically illustrative of the invention, the alarm system includes a timer 16 having resettable means and arranged to be preset to a selected time cycle. As
shown in FIG. 1, the timer 16 is preferably suitable mounted on the wall 17 of the bathroom adjacent to the commode C. The timer 16 may be of any well known, commercially available type which is provided with a manually operated knob 18 and associated dial 19 by means of which the selected time cycle may be preset on the timer. As is well known, the positioning of the knob 18 to the selected time cycle initiates the running of the time cycle, following which the action controlled by the timer commences The timer also includes resettable means (not shown) which when actuated during the time cycle automatically resets the timer to the original time cycle. Such a timer is readily available commercially and one example of such a timer is available from the Eagle Signal Division of Gulf and Western Industries, Inc. and designated as the CYCL-FLEX timer, Cat. No. HPS 108601. Such a timer has an adjustable dial setting of between 1 and 30 hours.
The system of the invention also includes alarm means designated generally by the numeral 21 which may be of any suitable type such as siren, horn or the like which, when actuated, produces an audible alarm of an intensity sufficient to alert others in the area of a need for help in the area of the alarm. Preferably such an alarm means 21 is mounted on the outer wall 22 of the residence. It should be understood that if desired a visual alarm may also be used either alone or in combination with the audible alarm or the alarm may be in the form of a tape recorder or the like'by means of which a recorded message is transmitted to police headquarters, etc., over phone lines, etc.
Means controlled by the timer are provided for actuating the alarm means upon termination of the time cycle present on the timer 16. More specifically, the alarm actuating means include first circuit means for connecting the alarm 21 and the timer 16 to an associated source of electrical power. The timer 16, which is preferably electrically operated, is provided with a power cord 23 including a pair of conductors terminat ing in a plug 24 for insertion in a wall receptacle 26 mounted in a conventional manner on the wall 17 of the bathroom, the timer being suitably hung from the wall 17 adjacent the commode C. As is well known, wall receptacle 26 is of the conventional type permanently connected to an associated source of electrical power.
The first circuit means also comprises a power cord 27 including a pair of conductors for connecting the timer 16 through the power cord 23 and the timer 16 operates in the conventional manner to connect the alarm 21 to the source of electrical power through cord 27 at the termination of the time cycle preset by means of the manual knob 18 on the timer.
The alarm system of the invention also includes means operatively associated with the commode actuating arm 12 for actuating the timer resetting means to reset the time cycle upon pivotal movement of the actuating arm into the operative position of FIG. 3 during the flushing of the commode. More specifically, the actuating means for the timer resetting means comprises second circuit means including a normally inoperative switch 31 which is responsive to the position of the actuating arm 12. The switch 31 is preferably a mercury switch of conventional construction having a pair of contacts 31a connected by means of conductors 32 to the timer 16 including the timer resetting means.
In the illustrated embodiment, the switch 31 is mounted on the actuating arm 12 as shown in FIGS. 2, 3 with the conductors 32 extending along the arm and out of the tank 11 beneath the tank lid 11a to the timer 16 as shown in FIG. 1. Neither the timer resetting means nor the connection of the conductors 32 to the timer 16 are shown as such a connecting arrangement is conventional with the use of the CYCL-FLEX reset timer referred to above. The switch 31 is operatively conditioned upon the pivotal movement of the actuating arm 12 from the inoperative position of FIG. 2 into the operative position of FIG. 3 to connect the timer resetting means to the source of electrical power for resetting the timer to the beginning of the preset time cycle.
As shown in FIG. 2, the actuating arm 12 is relatively level when the tank 11 is filled with water prior to use of the commode C. In the position of FIG. 2, the contacts 31a of the seitch 31 are closed, the mercury puddle 31b in the switch being disposed directly on the contacts of the switch 31 as shown. When the commode is flushed by movement of the operating handle in the direction of the arrow I, the actuating arm 12 moves upwardly in the direction of the arrow P so that the mercury puddle 31b is being disposed towards the end of the switch opening the contacts and initiating the resetting means in the timer 16. FIG. 4 is a block diagram of the circuit arrangement of the mercury switch 31, the timer 16 and the-alarm 21.
In the operation of the invention with the system installed'as shown in FIG. 1, the person using the system presets the timer to a time cycle which would be somewhat longer than the maximum period between uses of the commode C by the individual. As the timer 16 has a relatively wide range, an appropriate time cycle, by way of example, would be 12 hours since it is an accepted fact that an individual would use the commode C at least once during an 8-hour period. It should be understood that the timer 16 can be set for a period of time greater or less than 12 hours depending on individual preference. When the timer 16 is initiated by setting the operating knob 18, the time cycle begins. As the commode C will be flushed prior to the expiration of the time cycle under normal conditions, the actuation of the arm 12 opens the contacts 31a in the mercury switch 31 actuating the timer resetting means so that the timer returns to the beginning of the time cycle which once again begins to run. Thus, as long as the individual is able to use the commode C, the termination of the time cycle on the timer l6 and the actuation of the alarm 21 is never reached. If the individual is incapacitated and unable to summon help, the lapse of the time cycle actuates the alarm 21 which if audible is heard by people in the area or, if in some other form, transmits a message for help so that rescue orassistance is obtained promptly for the incapacitated person.
While there has been described what at present is considered to be the preferred embodiment of the invention, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the invention.
