1. Field of the Invention

The present invention relates to a silent alarm clock and more particularly pertains to waking a first user prior to waking a second user.

2. Description of the Prior Art

The use of silent alarms is known in the prior art. More specifically, silent alarms heretofore devised and utilized for the purpose of alerting one person without disturbing others are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

By way of example, the prior art discloses in U.S. Pat. Nos. 4,028,882 to Mucheryan; 4,218,875 to Rothman; 5,043,956 to Tsukada et al.; 5,089,998 to Rund; 4,920,525 to Meister; 4,093,944 to Mucheryan; 5,023,853 to Kawata et al.; 4,456,387 to Igarashi; and 5,282,181 to Entner et al.

In this respect, the silent alarm clock according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of waking a first user prior to waking a second user.

Therefore, it can be appreciated that there exists a continuing need for a new and improved silent alarm clock which can be used for waking a first user prior to waking a second user. In this regard, the present invention substantially fulfills this need.

In view of the foregoing disadvantages inherent in the known types of silent alarms now present in the prior art, the present invention provides an improved silent alarm clock. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved silent alarm clock which has all the advantages of the prior art and none of the disadvantages.

To attain this, the present invention essentially comprises a device to be utilized by a first user and a second user where the first user is awakened prior to the second user. Such device includes a portable receiver unit. The receiver unit has a housing with an interior space and a pair of bands coupled thereto.

With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved silent alarm clock embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The present invention, the new and improved silent alarm clock, is comprised of a plurality of components. Such components in their broadest context include a portable receiver unit and a base unit. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

More specifically, it will be noted that the system 10 to be utilized by a first user and a second user where the first user is awakened prior to the second user includes a portable receiver unit 12. The receiver unit has a housing with an interior space and a pair of bands 14 coupled thereto. A pair of pile fasteners 16 are situated at ends of the bands for allowing the securement of the receiver unit to a wrist 18 of the first user. The receiver unit includes a vibrator 20 situated within the interior space of the housing. The vibrator includes a motor 22 and a disk-shaped weight 24 eccentrically coupled to a rotor thereof. The vibrator is adapted to create a vibrating sensation upon the receipt of an activation signal. For allowing the receipt of radio signals via free space, a receiver 26 is included with an associated decoder 28 situated within the interior space of the housing and electrically connected between an antenna 30 and the vibrator. The decoder affords the transmission of the activation signal only upon the receipt of a predetermined radio signal. To provide power to the receiver unit, a rechargeable battery 32 is included with a pair of associated contacts and a charger 36 adapted to allow the recharging of the battery upon the application of power to the contacts. Ideally, the housing and bands of the receiver unit are light weight and include a cloth covering for allowing the first user to sleep while wearing the present device.

As best shown in FIG. 1, a base transmitter unit 38 has a horizontally oriented bottom portion 40 with a top face, a bottom face, and a periphery formed therebetween. The base transmitter unit also has a vertically oriented top portion 42 with a front face, a rear face, and a periphery formed therebetween wherein both portions together define an interior space. The base transmitter unit also includes a recharging base having a pair of contacts 44 situated on a top surface of the vertically orientated portion of the housing. A lip 46 is included for maintaining communication between the contacts of the receiver unit and the contacts of the base unit during recharging. Preferably, such lip has an L-shaped configuration with a first section situated about the contacts of the base unit for specifically holding the housing of the receiver unit and a second section connected to the first and depending therefrom so as to allow the containment of the bands. A recharge button 48 is positioned on the top surface of the top portion of the housing adjacent the contacts. Working in conjunction with the recharge button is a remote charge sensor 50 situated within the interior space of the base for generating a charge signal upon the depression of the recharge button effected by the securement of the housing within the lip during charging.

Also included within the base housing is a clock unit 52 having associated control circuitry adapted to generate a current time signal and allow the generation of both an audio alarm signal and a remote alarm signal at a first predetermined time and a second predetermined time. A snooze button 55 is included for precluding the generation of both the audio alarm signal and the remote alarm signal for approximately 5-10 minutes upon the depression thereof. A light emitting diode clock display 56 is situated on the front face of the vertically oriented portion of the housing for displaying numerical data representative of the current time signal. Control keys 58 are included for allowing a user to define the first predetermined time and second predetermined time. Such keys may also be employed for other conventional clock functions such as setting the current time. Situated on the front face of the top portion of the housing is a speaker 60 adapted to generate an audio alarm in the form of an electric beeping sound upon the receipt of the audio alarm signal. It should be noted that a radio may be included for allowing the speaker to emit music or other radio programs upon the receipt of the audio alarm signal. A transmitter 62 with an associated encoder 64 is coupled to an antenna 66 and adapted to emit the predetermined radio signal generated by the encoder upon the receipt of the remote alarm signal. A transmitter enabler 68 is coupled between the control circuitry of the clock unit and the transmitter. The transmitter enabler is adapted to allow the communication of the remote alarm signal therebetween only upon the lack of receipt of the charge signal via the remote charge sensor. A speaker disabler 70 is coupled between the control circuitry of the clock unit and the speaker for allowing the communication of the audio alarm signal therebetween only upon the receipt of the charge signal via the remote charge sensor. A LED 72 is connected to the remote charge sensor for emitting light upon the lack of receipt of the charge signal via the remote charge sensor. The encoder and decoder of the present invention are utilized to preclude inadvertent actuation of the present invention due to stray radio signals.

Essentially, both the transmitter enabler and the speaker disabler govern whether the remote alarm signal or the audio alarm signal generated by the control circuitry are employed to effect a silent or audible alarm, respectively. The function of the speaker disabler and the transmitter enabler is, in turn, determined via the remote charge sensor by the presences of the receiver unit in the recharging position thereof. As such, the selection of a silent or audible alarm is conveniently afforded. In use, the first user is awakened via the vibrator at the first predetermined time and places the receiver unit within the recharging base thereafter. The second user is then awakened at the second predetermined time via the audio alarm.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
