Description
The present invention pertains to a wireless remote control door lock system, particularly adapted for residential entry and exit doors, for example.
The development of wireless remote control locks for motor vehicles and the development of wireless remote controls for operating residential and commercial garage doors has led to substantial improvements in the conveniences and security afforded in everyday life to persons living in both urban and rural settings. However, the improvements realized through the use of wireless remote controlled vehicle door locks and wireless remote control operators for residential and commercial garage doors have not been transferred to or adapted for use with residential entry and exit doors, for example. Accordingly, the conveniences and increased personal security that persons enjoy when entering a motor vehicle or when operating a garage door, for example, have not been available to entry and exit from a person's residence, office or other place of occupancy.
There are many instances when remote control of a pedestrian door is a residence, office or other building entry is desirable. With conventional key locks, for example, it is difficult to lock or unlock the door in poor lighting conditions. Children and elderly persons often have difficulty in manipulating keys and key operated locks. Moreover, it is often desirable to be able to lock or unlock a door from a distance during inclement weather or when a person's hands are occupied when approaching a door, such as when carrying various articles. Further, it is desirable for security purposes to be able to remotely control locking and unlocking of a door from relatively close proximity to the door. Still further, the development of suitable remotely controllable personnel entry and exit doors for residential as well as commercial buildings has also been at least somewhat retarded by the lack of a suitable system which can be easily retrofitted to existing structures as well as easily fitted to new buildings while such are being constructed.
It is to these ends that the present invention has been developed.
The present invention provides a wireless remote controlled lock system, particularly adapted for personnel entry and exit doors for residential as well as commercial buildings.
In accordance with one aspect of the present invention a remote control door lock system is provided which utilizes a wireless signal transmitter and receiver combination and which may be easily adapted to buildings during new construction or retrofitted to existing buildings to provide a suitable remotely controllable system.
In accordance with another aspect of the present invention a remote control door lock system has been developed wherein a door latching mechanism may be easily fitted with an electrical power operated striker plate assembly which is connected to a control unit including a wireless signal receiver. In this way, existing doors may be conveniently retrofitted with the remote controlled lock system and doors in newly constructed buildings may also be fitted, conveniently, with the lock system including the power operated striker plate assembly.
The remote controlled lock system of the present invention is also advantageously adapted to be connected to a conventional residential or commercial building AC electric power distribution system. In this regard, the system of the invention includes a control unit including a rectifier for converting AC electrical power to low voltage DC electrical power. The control unit also includes control relay means which provide, in accordance with a signal received by the wireless receiver, for operation of a low voltage DC power operated movable lock striker plate member for momentary unlocking of a door or continuous unlocking of the door, as selected by an operator of the lock system.
The present invention advantageously utilizes commercially available radio frequency range transmitter and receiver devices and wherein the transmitter device may be easily incorporated in a key ring fob or the like and conveniently carried by a person desiring access to a particular door.
Those skilled in the art with further appreciate the features and advantages of the remote controlled door lock system of the present invention together with other superior aspects thereof upon reading the detailed description which follows in conjunction with the drawing.
In the description which follows like parts are marked throughout the specification and drawing with the same reference numerals, respectively. The drawing figures are not necessarily to scale and conventional symbols are used in the schematic diagrams to illustrate certain components.
Referring to FIGS. 1 , 2 and 2A, there is illustrated a typical residential dwelling structure 10 having an inwardly opening pedestrian entry and exit door 11 in a front wall 12 of the structure to provide ingress and egress, at will, by authorized persons. The door 11 is of conventional construction and is supported on hinges 11a for generally horizontal swinging movement between open and closed positions. The structure 10 includes a conventional door jamb 13 which may be formed of wood, plastic or metal and provided with a suitable recess 13a, FIGS. 2 and 2A , in which is fitted a striker plate assembly 14.
Clearly, it is advantageous for persons having authorization to enter and exit the structure 10 to be able to remotely control locking and unlocking of the door 11 for convenience, such as when such persons are carrying various objects, and for personal security reasons. Typically, it is be advantageous to control operation of locking and unlocking the door 11 from a distance of as much as 100 feet to 150 feet away. This distance is within the operating range of certain categories of small, hand-held, battery operated radio frequency transmitter devices. Other wireless signal transmitting and receiving devices, including infrared signal transmitters and receivers and the like are contemplated with respect to transmitter and receiver parts of the lock system of the present invention.
Referring primarily to FIG. 2 , there is illustrated a perspective view from the interior of the structure 10 illustrating a support member 15 for the striker plate assembly 14 and which is secured to the door jamb 13 by conventional fasteners 15a. The striker plate assembly 14 may be of a type commercially available, such as from ROFU International Corporation, Tacoma, Wash., as their Electric Door Strike. The striker plate assembly 14 is adapted to mount in a suitable recess 13a in the door jamb 13 of the structure 10, as shown, in place on a conventional door latch striker plate. Referring to FIGS. 2 and 2A , the striker plate assembly 14 includes a latch striker plate member 18 which is moveable between a door latching position shown and a retracted position, shown by the alternate position lines in FIG. 2A , to allow a retractable door latch or bolt member 11b, for the door 11 to move into and out of a recess 19 in the striker plate assembly 14 to allow the door 11 to move between open and closed positions. Preferably, the striker plate assembly 14 is energized to release the striker plate 18 for movement to the open or retracted position and the striker plate 18 is moved to and held in the closed and door latching position shown in FIG. 2 when the striker plate assembly 14 is de-energized. The striker plate member 18 may be operable to be forcibly moved to a position to allow the door 11 to open without retraction of bolt 11b or the striker plate member 18 may just be released to allow the door latch 11b to move the striker plate member 18 to the alternate position shown in FIG. 2A in response to pushing or pulling the door towards its open position. In any case reference herein to movement of the striker plate member 18 to the door release or unlock position may also refer to a condition wherein the member 18 is actually moved by the latch or bolt 11b after being released for such movement.
The striker plate assembly 14 is connected to a control unit 21. FIG. 2 , via suitable electrical power conductors 17a and 17b. Moreover, the striker plate assembly 14 is adapted to operate on low voltage DC (direct current) power, to energize the moveable striker plate member 18 to move to the open position. As shown in FIG. 2 , the control unit 21 may be provided in a suitable enclosure 23 which may be mounted in a wall cavity 12a for the wall 12 or mounted on the interior surface 12b of the wall in an inconspicuous location and connected to a suitable source of AC (alternating current) electric power, such as conventional 110 volt AC household power, via conductor means 25. A conventional connector or plug 22, see FIG. 3 , may be operably connected to the conductor means 25 for control unit 21.
Referring now to FIG. 3 , the control unit 21 is characterized by a suitable power transformer 24 connected to the plug 22 and adapted to reduce conventional 110 volt AC power to the control unit to low voltage AC power, such as a nominal 6.3 volts, for example. A suitable bridge rectifier 26 is provided in the control unit 21 and, is operably connected to the transformer 24 and to a suitable voltage regulator 28. A suitable electrolytic capacitor 30 is also in circuit with the rectifier 26 and the voltage regulator 28 to provide regulated positive twelve volt DC power for all components of the control unit 21 and for the striker plate assembly 14.
Referring further to FIG. 3 , the control unit 21 includes a radio frequency range wireless receiver unit 32 disposed therein and having suitable antenna means 34 for receiving a radio frequency range control signal from a transmitter unit 36 comprising a transmitter 36a disposed in a key ring fob 36b or the like, for example. The transmitter unit 36 is also provided with suitable antenna means 38 for emitting radiation in the radio frequency range for reception by the receiver 32. The transmitter unit 36 is preferably provided with at least two momentary push button operated switches 37a and 37b whose operating functions will be explained in further detail herein. The receiver unit 32 and the transmitter unit 36 may both be of a type commercially available and suitable for remote control operation for up to approximately 150 feet operating range between the transmitter and receiver. For example, the receiver and transmitter combination may be of a type manufactured by AAMP of America as their model RXS300 multi-channel receiver module. The transmitter and receiver combination may be operated using only one or both of the transmitter switches 37a or 37b, for example, in accordance with the description herein.
Referring further to FIG. 3 , the receiver unit 32 has a power ground terminal 32a, a twelve volt power supply terminal 32b, an internal receiver relay power terminal 32c and terminals 32d and 32e which are connected to respective relays 40 and 42, in circuit with the receiver 32 and the source of DC power, as shown. Still further, the control unit 21 includes a mode selector switch 44 in circuit with relays 40 and 42, as shown, and having two selectable operating positions as indicated by contacts 44a and 44b in FIG. 3. A switch actuator 44c is operably connected to switch 44 for selecting the operating position thereof.
However, if the transmitter 36 is activated a second time by operation of one of either switch 37a or 37b, internal switch means 32g within the receiver 32 and operably connected to terminal 32d closes momentarily causing relay 42 to move contactor 42b to the alternate position shown in FIG. 3 , interrupting current flow through switch 44 in the position shown in FIG. 3 , and relay 40. This action causes relay 40 to be de-energized and move contactors 40a and 40b to the solid line positions shown in FIG. 3 , thus de-energizing the electronic striker assembly 14 and allowing the striker plate member 18 to move to and remain in the lock or latching position for the door 11.
The alternate position of switch 44 may be selected by a user of the door lock system by operating the switch actuator 44c suitably mounted on the control unit 21. When the receiver 32 receives a signal from the transmitter unit 36, switch means 32f is momentarily closed as mentioned previously, for about 3.5 seconds, for example, energizing relay 40 to move the contactors 40a and 40b to the alternate positions shown in FIG. 3 and energizing the striker assembly 14 to allow the striker 18 to unlock the door. However, since the switch 44 is in the alternate position, the relay 40 will not latch but will remain energized only as long as the switch means 32f is closed.
Accordingly, the door lock system of the present invention provides alternate operating modes wherein a door 11 associated with the lock system may remain unlocked unless commanded to be relocked or the door remains unlocked for only a sufficient amount of time to quickly open the door and exit or enter the building 10 or any structure associated with a door and the door lock system according to the invention.
The installation and operation of the door lock system of the present invention is believed to be readily understandable to those skilled in the art from the foregoing description. The striker assembly 14 may be easily retrofitted to existing door jambs by replacing conventional fixed striker plates with the striker assembly 14 and by connecting the striker assembly to the control unit 21 which may be mounted either within a wall space as illustrated, or on the interior surface thereof. In either case it is convenient to place the enclosure 23 in such a position that access to the actuator 44c for the switch 44 may be easily obtained to select the working position of the switch and control unit 21. The transmitter unit 36 may include additional operating controls, not shown, such as controls for operating a garage door opener or controls for locking and unlocking the doors of a motor vehicle. Moreover, the transmitter unit 36 and the receiver 32 may be adapted to provide for a so-called rolling transmission code to prevent unauthorized operation of the control unit by a person gaining access to the code transmitted by the transmitter unit 36 at any one transmission event.
Although a preferred embodiment of the invention has been described in detail herein those skilled in the art will recognize that various substitutions and modifications may be made to the lock system disclosed without departing from the scope and spirit of the appended claims.
