DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 8 thereof, a new door bell answering system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 8, the door announcement system 10 generally comprises at least one transmitting assembly 12 sending an indicator signal when the at least one transmitting assembly 12 is actuated. The at least one transmitting assembly 12 includes a frame 14 positioned on a support surface adjacent to a door. The frame 14 has an upper surface 16 having a depression 18 therein. A lower contact strip 20 is coupled to the frame 14. The lower contact strip 20 is positioned in the depression 18 along a bottom face 21 of the depression 18. The lower contact strip 20 is in electrical communication with a power supply 22 positioned in the frame 14.
The at least one transmitting assembly 12 additionally includes a mat 24 coupled to the frame 14 and extending across the depression 18 of the frame 14. The mat 24 is positioned adjacent to the upper surface 16 of the frame 14. The mat 24 is comprised of a flexible and fluid impermeable material to inhibit liquid entering the depression 18. The mat 24 flexes when weight is applied to the mat 24. The mat 24 returns to its original configuration when the weight has been removed from the mat 24.
The at least one transmitting assembly 12 also includes at least one upper contact strip 26 coupled to the mat 24 and positioned in the depression 18 of the frame 14. The at least one upper contact strip 26 is positioned in a spaced relationship to the lower contact strip 20 when the mat 24 is in its original configuration. The at least one upper contact strip 26 is in electrical communication with the power supply 22. The at least one upper contact strip 26 contacts the lower contact strip 20 when weight is applied to the mat 24 to complete an electrical circuit. A transmitter 28 is coupled to the frame 14. The transmitter 28 is in electrical communication between the lower contact strip 20 and the power supply 22. The transmitter 28 wirelessly transmits the indicator signal when the at least one upper contact strip 26 contacts the lower contact strip 20 to complete the electrical circuit.
In an embodiment, as shown in FIGS. 6 and 7, the at least one transmitting assembly 12 may include a proximity transmitter 30 coupled to a collar 32 positioned around a neck of an animal. The proximity transmitter 30 transmits the indicator signal over a limited range, such as less than 30 feet, wherein the indicator signal is received by the at least one receiving assembly 34 when the animal is positioned near the door. As shown in FIG. 7, the at least one transmitter 28 assembly may include a plurality of transmitters 28 that can be used in conjunction with each other to allow several doors and several animals, or any combination thereof, to be monitored at the same time.
At least one receiving assembly 34 engages an electrical outlet 1 to provide power to the at least one receiving assembly 34. The at least one receiving assembly 34 is in electrical communication with a lamp 2 to turn the lamp 2 on and off when the at least one receiving assembly 34 receives the indicator signal. The at least one receiving assembly 34 includes a case 36 housing a microprocessor 38. The microprocessor 38 is in electrical communication with the electrical outlet 1 to receive power from the electrical outlet 1. A transceiver 40 is positioned in the case 36 and is in electrical communication with the microprocessor 38. The transceiver 40 receives the indicator signal and actuates the microprocessor 38.
The at least one receiving assembly 34 also includes a switch 42 in electrical communication with the microprocessor 38 and positioned in the case 36. The switch 42 is actuated between a closed condition and an open condition by the microprocessor 38 when the transceiver 40 actuates the microprocessor 38. An at least one accessory outlet 44 is coupled to the case 36 and in electrical communication with the switch 42. The at least one accessory outlet 44 receives a plug of the lamp 2. The switch 42 controls power to the at least one accessory outlet 44 to turn the lamp 2 on and off. An audio emitter 46 is coupled to the case 36 and in electrical communication with microprocessor 38. The audio emitter 46 is actuated by the microprocessor 38 to emit an audible sound when the transceiver 40 actuates the microprocessor 38.
In the case of multiple transmitting assemblies 12, the microprocessor 38 can actuate the switch 42 to create an unique pattern of flashes of the lamp 2 and unique audio tones from the audio emitter 46 to indicate which one the transmitting assemblies 12 is being actuated. Additionally, multiple receiving assemblies 34 may be used at various locations through out a structure to allow multiple lamps 2 to be flashed so that the actuation of the at least one transmitting assembly 12 may be observed from different locations in the structure.
The multiple receiving assemblies 34 may include a main receiving assembly 48 and a pager assembly 50. The main receiving assembly 48 has a mode switch 52 electrically coupled to the microprocessor 38. The mode switch 52 actuates the microprocessor 38 to switch between a silent mode and an all features mode. In the silent mode the main receiving assembly 48 does flash the lamp 2 and does not actuate the audio emitter 46 to emit an audible sound but actuates the transceiver 40 to transmit a pager signal to the pager assembly 50. The pager assembly 50 is worn by a person and upon receipt of the pager signal the pager assembly 50 vibrates to alert the person of activity at the door. Additionally, the pager assembly 50 may be illuminated to provide a visual signal to the person when the pager assembly 50 receives the pager signal. The pager assembly 50 also includes a display 54 to display the time the pager signal was received and which of the transmitting assemblies 12 transmitted the indicator signal to the main receiving assembly 48.
The all features mode allows the main receiving assembly 48 to flash the lamp 2 and actuate the audio emitter 46 to emit the audible signal to alert the person of activity at the door. The main receiving assembly 48 may also have a pair of mode lights 56 being in electrical communication with the microprocessor 38. A first one of the mode lights 56 is illuminated when the mode switch 52 is switched to the silent mode and a second one of the mode lights 56 is illuminated when the mode switch 52 of switched to the all features mode. The main receiving assembly 48 also includes a locator button 58 being electrically coupled to the microprocessor 38. The locator button 58 is actuated to send a locating signal to the pager assembly 50 to actuate the pager assembly 50 to emit an audible locating tone to facilitate location of the pager assembly 50.
The multiple receiving assemblies may also include a plurality of remote receiving assemblies 60, as shown in FIG. 8. Each of the remote receiving assemblies 60 receives signals from the main receiving assembly 48 to indicate activity at the door. Additionally, each of the remote receiving assemblies 60 includes a pet light 62 and a mat light 64 being electrically couple to the microprocessor 38 of the associated one of said remote receiving assemblies 60. The pet light 62 is illuminated to indicate the presence of the animal at the door when the main receiving assembly 48 receives the indicator signal from the proximity transmitter 30. The mat light 64 is illuminated when the main receiving assembly 48 receives the indicator signal from the transmitter 28.
In use, the frame 14 is positioned on the support surface adjacent the door where a person or animal must step on the mat 24 when positioned in front of the door. Weight on the mat 24 presses the at least one upper contact strip 26 against the lower contact strip 20 to complete the electrical circuit and actuate the transmitter 28 to transmit the indicator signal. The transceiver 40 of the receiving assembly 34 receives the indicator signal and actuates the microprocessor 38 to flash the lamp 2 and emit the audible sound from the audio emitter 46 to indicate that there is a person or animal positioned outside the door.
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.
