The invention generally pertains to alerting devices, and more particularly to an audio alerting device that is attached to an inner surface of a windowpane through which is visible a device activation target. When a person touches the outside of the windowpane at the area encompassing the device activation target, the audio alerting device is activated.
The use of an alerting device to indicate that a person wishes to enter a home or a commercial building is in widespread use. Typical alerting devices include hard-wired chimes, bells or buzzers that are located within a home or a building and that are activated by a person from the outside of the home or the building structure. The use of portable alerting devices that can be easily moved from one location to another and that are easily attached to an inner surface of a structure e.g., an inner surface of a windowpane was not found in the prior art. However, the following U.S. patents are considered related:
The U.S. Pat. No. 6,897,765 patent discloses a remote control device that when actuated by a user transmits a coded signal to a sensor. The sensor is associated with a doorbell that receives the signal and causes activation of the doorbell. The sensor has multiple settings which control operSation of the doorbell.
The U.S. Pat. No. 5,894,262 patent discloses a doorbell circuit that detects when one of a plurality of doorbell switches is depressed and provides an audible indication for each specific doorbell switch that is depressed. The doorbell circuit includes a detector circuit that is connected in parallel across one of the doorbell switches.
The U.S. Pat. No. 4,764,953 patent discloses an apparatus for providing remote answering of a doorbell. The apparatus includes a circuit for receiving a doorbell signal indicative that a doorbell switch has been actuated. An autodialing circuit is coupled to and is responsive to the receiving circuit and a telephone line for dialing a telephone number responsive to the doorbell signal. An alerting circuit generates an alert signal to be transmitted over the telephone line to the telephone number dialed by the autodialing circuit. The alert signal then alerts a party answering the remote telephone to the fact that the party is responding to a doorbell rather than a normal telephone call.
The U.S. Pat. No. 3,624,646 patent discloses a thermometer/chime combination. The usual chime circuitry is modified to indicate the outdoor temperature during the period of time that the chime is not in actual use. Thus, the composite circuitry, which normally indicates the temperature, sounds the chime tone when an exterior pushbutton switch is activated.
For background purposes and as indicative of the art to which the invention relates, reference may be made to the following remaining patents found in the search:
The window-attached alerting device, which is also known as WindowBell™, is designed for use with any glass door or window that is attached to a building such as a home, office or storefronts. The inventive window-attached alerting device instantly provides a doorbell type device without requiring the use of external wiring, drilling holes or the need to have an additional alerting device attachment structure attached to an outer surface of the building. Any building can have at least one additional alerting device attached to any glass door or window.
In its basic design configuration the window-attached alerting device functions in combination with a windowpane that is located within a window frame that is attached to a building, and that includes an inner surface and an outer surface. The window-attached alerting device is comprised of:
A. An alerting device enclosure having an outer side and an inner side. The outer side has an enclosure/window attachment means, such as double-sided adhesive tape, which allows the enclosure to be releasably attached to the inner surface (inside) of the windowpane. Since the alerting device enclosure is attached inside a building it is protected from inclement weather or theft.
B. A battery-powered electronics circuit that is located within the alerting device enclosure and that has circuit means for producing an audible alerting device signal that is activated by an electrode, which is located on an inner surface of the inner side of the alerting device enclosure. The electrode is activated from the outer surface (outside) of the windowpane when a person's finger or hand or other capacitively conductive material is placed proximate to an area of the windowpane that encompasses the location of the electrode.
The activated electrode produces a signal that allows the window-attached alerting device to produce a selectable “DING DONG” or “DONG DING” chime.
In view of the above disclosure, the primary object of the invention is to produce an alerting device having an electronics circuit that includes an alerting device activating electrode. The alerting device is located within an alerting device enclosure that is attached to an inner surface of a windowpane. The alerting device is activated when a person places his/her finger or hand on an outer surface of the windowpane on an area that encompasses the location of the electrode.
In addition to the primary object of the invention, it is also an object of the invention to produce a window/attached alerting device that:
These and other objects and advantages of the present invention will become apparent from the subsequent detailed description of the preferred embodiment and the appended claims taken in conjunction with the accompanying drawings.
The best mode for carrying out the window-attached alerting device is presented in terms of a preferred embodiment that is disclosed in three design configurations. All three configurations have a commonality in that the electronics circuit that operates the alerting device is located within an enclosure that includes an outer side and an inner side. The outer side is removably attached to the inner surface of a windowpane, which allows the inner side of the enclosure to extend from the inner surface of the windowpane. To activate the window-attached alerting device a person simply places his/her finger or hand proximate to indicia such as a target that is placed on the outer side of the alerting device enclosure and that is visible through the windowpane. The alerting device can consist of a chime, a buzzer, an audio message, or the like. However, for purposes of brevity, only an alerting device consisting of a chime and a buzzer are disclosed.
The first design configuration which is also the preferred embodiment of the window-attached alerting device 10, as shown in
The electronics circuit 12 is comprised of the following nine components: a d-c power source 14, a power ON/OFF and chime select switch 16, a power rectifier and filter circuit 18, a voltage regulator circuit 20, an electrode 22, a touch sensing circuit 24, a chime generator circuit 26, an audio amplifier 28, and a loudspeaker 30. The alerting device enclosure 40 is comprised of an outer side 42, an inner side 44, an enclosure/window attachment means 46, and indicia 52. The alerting device 10 functions in combination with a windowpane 60 having an inner surface 62 and an outer surface 64. Note that the electronic elements are designated with even numbers and the corresponding signals are designated in odd numbers.
The d-c power source 14, as shown in
The power rectifier and filter circuit 18, as shown in
This regulated d-c voltage 21 is applied to the contact (D) of the power ON/OFF and chime select switch 16, to the touch sensing circuit 24, and to the chime generator circuit 26.
