BRIEF DESCRIPTION OF THE VARIOUS EMBODIMENTS OF THE INVENTION
FIG. 4 is a schematic representation of the door bell answering system according to another embodiment of the invention.
Prior to proceeding to the more detailed description of the present invention, it should be noted that, for the sake of clarity and understanding, identical components which have identical functions have been identified with identical reference numerals throughout the several views illustrated in the drawing figures.
Reference is now made, to FIGS. 1-4, wherein there is shown a door bell answering system, generally designated 20, which comprises an answering device, generally designated 30, internally disposed in a predetermined portion of a dwelling 10 and connected to an electrical power source 12 disposed within such dwelling 10.
According to one embodiment of the invention, best shown in FIGS. 2-3, the answering device 30 includes a housing 32, a control means 34 capable of at least storing and playing back at least one audio message, a speaker 36, located behind the port 37 of the housing 32, for broadcasting the at least one audio message and a predetermined plurality of function keys 38 manually operable from an exterior surface of the housing 32 for operating the control means 34 and the speaker 36.
The door bell answering system 20 further includes an externally disposed communication means, generally designated 40, preferably connected to such electrical power source 12 and including a housing 42 mounted to an exterior surface of such dwelling 10. The communication means 40 is preferably disposed in close proximity to the door 14 of such dwelling 10. Such communication means 40 further includes a microphone 44, preferably disposed behind a port 45 of the housing 42, a first manually operable switch 46 for activating a door bell 16 which is audibly recognizable internal to such dwelling 10 and a second manually operable switch 48 for activating the answering device 30 and the microphone 44. Preferably, each of the first switch 46 and the second switch 48 is a pushbutton type suitable for operation under undesirable weather conditions such as rain, snow, dust and the like. A visitor, upon depressing, preferably continuously, such second switch 48, is able to record such at least one audio message by speaking into the microphone 44. The visitor may record additional messages by depressing the second switch 48 again.
A first predetermined indicia 50 is provided for characterizing the first manually operable switch 46 and a second predetermined indicia 52 may be provided for characterizing the second manually operable switch 48. Each of such first indicia 50 and second indicia 52 may be disposed on the outer surface of the housing 42 adjacent its respective switch or may be disposed directly on the surface of such respective switch.
Such at least one audio message is transmitted between the communication means 40 and the answering device 30 through a connection means, generally designated 60, which in the presently preferred embodiment of the invention is at least one wire 62, as best shown in FIGS. 1 and 3.
In operation, the visitor will first depress the first switch 46 and wait for an occupant of the dwelling 10 to unlock or open the door 14. If such event does not occur, the visitor then depresses the second switch 48 and speaks in the direction of the microphone 44. The audio message received by the microphone 44 is transmitted thorough the at least one wire 60 to the answering device 30 and is recorded by the control means 34. The occupant then uses the function keys 38 to retrieve the recorded at least one audio message which is broadcast through speaker 36. It will be appreciated that the invention disclosed supra is advantageous when the occupant of the dwelling 10 is not available or not inclined to unlock or open the door 14.
According to another embodiment of the invention, the answering device 30 is provided with a microphone 38 and the communication means 40 is provided with a speaker 54 enabling the visitor and the occupant of such dwelling 10 to audibly communicate in a two-way intercom type communication and further enhance safety of the occupant when the visitor is unfamiliar or an undesirable person.
Those skilled in the art will appreciate that such at least one wire 62 is economical to connect adjacently positioned communication means 40 and the answering device 30, when such answering device 30 is attached to the interior wall portion of dwelling 10, as best shown in FIG. 1. To provide for ease of remote installation of answering device 30, such transmitting means 60 may be a wireless type including a transmitter 64 disposed within the externally disposed communication means 40 and a receiver 66 disposed within the answering device 30. Accordingly, a second control means 56 will be provided within the communication means 40 and the control means 34 will be adapted to enable such wireless communication between the communication means 40 and the answering device 30.
Furthermore, to enable two-way wireless communication, the door bell answering system 20 will be adapted with a pair of transceivers 68, wherein the first transceiver 68 is disposed within the answering system 30 and the second transceiver 68 is disposed within the communication means 40. Accordingly, the control means 34 and 56 will be adapted to enable such two-way wireless communication.
In further reference to FIGS. 1-2 and according to yet another embodiment of the invention, the communication means 40 is provided with a camera 70 and the answering device 30 is provided with a display 72 and, preferably, its respective set of function keys 74 for enabling the occupant of dwelling 10 to visually identify the visitor. It will be understood that a second display 72 may be provided within the communication means 40 and a second camera 70 may be provided within the answering device 30 for enabling the visitor and the occupant of such dwelling 10 to audibly and visually communicate therebetween.
Although the present invention has been shown in terms of the communication means 40 containing the switch 46 for activating door bell 16, it will be apparent to those skilled in the art, that the present invention may be applied to the door bell 16 having an independent activating switch.
Furthermore, the communication means 40 may be adapted with a replaceable battery to minimize installation costs and eliminate connection of such communication means 40 to the power source 12 of the dwelling 10.
Thus, the present invention has been described in such full, clear, concise and exact terms as to enable any person skilled in the art to which it pertains to make and use the same. It will be understood that variations, modifications, equivalents and substitutions for components of the specifically described embodiments of the invention may be made by those skilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims.
