BACKGROUND OF THE INVENTION
[0002] The present invention relates to a mobile security system,
and more particularly to such a mobile security system, which
comprises a warning signal transmitter unit installed in the place
to be protected to monitor the surrounding, an auto dialing unit
having a signal receiver, and a cellular phone coupled to the auto
dialing unit and driven by the auto dialing unit to call a
particular telephone number for help when the signal receiver
receives a radio warning signal from the warning signal transmitter
unit.
[0003] Following fast development of economics, the living quality
is greatly improved. Most families have a car for transportation.
However, in the modern society, there are many lazy people hoping
to gain without effort, and theft cases occur every day. In order
to improve the living quality of the surroundings, it is important
to reduce the frequency of occurrence of theft cases. A variety of
security system have been developed for this purpose. A regular
security system is generally comprised of a plurality of sensors
installed in fixed locations in the place or equipment to be
protected to monitor the surroundings, and alarm means connected to
the sensors. The alarm means is triggered to alarm when the sensors
detect an abnormal condition. Because the sensors are installed in
fixed locations, they can easily found out and damaged by the
intruder. When an abnormal condition occurs, the security person in
charge is informed to check the situation, and then to inform the
owner of the place or equipment under protection after checking.
Because the owner of the place or equipment under protection is not
informed before the security person goes to check the situation,
the owner of the place under protection may be unable to take the
necessary step in time. Further the alarm signal of the alarm means
can be heard or seen only within a limited distance from the place
or equipment under protection. If the owner of the place or
equipment under protection is beyond the effective range of the
alarm means, the security system may work in vain.
SUMMARY OF THE INVENTION
[0004] The present invention has been accomplished under the
circumstances in view. According to one aspect of the present
invention, the mobile security system comprises a warning signal
transmitter unit installed in the place or equipment to be
protected, an auto dialing unit having a signal receiver, and a
cellular phone coupled to the auto dialing unit. When the warning
signal transmitter unit detects an abnormal condition, it
immediately sends a warning signal to the signal receiver by radio,
and the signal receiver immediately drives the auto dialing unit to
dial a particular telephone number upon receipt of the warning
signal, so as to inform a particular person or security center to
take the necessary step. According to another aspect of the present
invention, the auto dialing unit can be a mechanical design, or an
electronic design as desired. Because the auto dialing unit is
coupled to the cellular phone and controlled by the warning signal
transmitter unit by radio, the auto dialing unit can be kept with
the cellular phone from sight.

sensor 11 detects a signal, it immediately drives the signal
transmitter 12 to send a warning signal into the air by radio. The
mechanical type auto dialing unit 20 comprises a signal receiver 21
for receiving the warning signal from the signal transmitter 12.
Upon receipt of the warning signal from the signal transmitter 12,
the signal receiver 21 immediately drives the auto dialing unit 20
to dial a particular telephone number, for example, the telephone
number of a telephone 3 or a sub-cellular phone 4 through the
master cellular phone 2, so as to inform a particular person or
security center to take the necessary step. The master cellular
phone 2 is recorded with a warning message, for example, the bark
of a dog. When the telephone 3 or sub-cellular phone 4 is
connected, the warning message, i.e., the bark of a dog is
transmitted from the master cellular phone 2 to the telephone 3 or
sub-cellular phone 4, informing the person in charge about the
occurrence of an abnormal condition.
[0020] Referring to Figures from 2 through 8, the mechanical type
auto dialing unit 20 comprises a rack 50, an adjustable cellular

device 100 by a circuit to provide the necessary working
voltage.
[0027] When in use, the master cellular phone 2 is placed on the
cellular phone carrier board 60 and secured in place by the sliding
locating plate 67, then the actuating bar 70 is turned relative to
the rack 50 from the non-working position shown in FIG. 2 to the
working position shown in FIGS. 5 and 6 and supported on the buffer
devices 56 and 57 and retained in the working position by the hook
plates 96 and 97, and then the sliding button 74 is adjusted on the
transverse arm 73 into vertical alignment with an "OK" key button 5
at the master cellular phone 2. When the signal receiver 21
receives a warning signal from the signal transmitter unit 10, the
control circuit board 81 immediately controls the contact switch 82
to turn on the motor 100, causing the motor 100 to rotate the
output shaft 101 and the cam 102 through two turns. Rotating the
cam 102 through two runs causes the horizontal pressure board 93 to
be reciprocated vertically twice, and therefore the "OK" key button
5 of the master cellular phone 2 is clicked twice at a fixed time
interval (see FIGS. 7 and 8) to dial up a particular telephone
number.
[0028] Because the cellular phone carrier board 60 is vertically
adjustable, the mechanical type auto dialing unit 20 fits cellular
phones of different thickness. However, because commercially
available cellular phones have different dimensions, it is
important to make the mechanical type auto dialing unit 20 capable
of fitting any of a variety of cellular phones.
[0029] Referring to FIGS. 2, 7 and 8 again, vertical mounting
grooves 58 are respectively provided at the vertical boards 51 and

phone holder 140 comprises a receiving chamber 141 fitting the
master cellular phone 2, and a plurality of mounting plugs (not
shown) respectively fastened to the vertical mounting grooves 58 at
the vertical boards 51 and 52 of the rack 50.
[0030] FIGS. 9 through 11 show an alternate form of the present
invention. According to this embodiment, the mechanical type auto
dialing unit 20' comprises a spring-supported holding down device
120 installed in the rack for holding down the master cellular
phone. The spring-supported holding down device 120 comprises a
lever 121 having an inner end 1211 pivoted to the horizontal board
53 and an outer end 1212 extended out of the horizontal board 53, a
substantially U-shaped plate 122 pivoted to the lever 121 by a
pivot 123 and disposed between the lever 121 and the horizontal
board 53, and two tensile springs 124 and 125 symmetrically
connected between the lever 121 and the horizontal board 53
adjacent to the pivot 123. The U-shaped plate 122 is turned about
the pivot 123, having two upwardly extended, angled clamping ends
1221 and 1222. The cellular phone carrier board 60' has two
parallel sliding openings 127 and 128 through which the angled
clamping ends 1221 and 1222 of the U-shaped plate 122 pass. The
tensile springs 124 and 125 pull the lever 121 in one direction,
keeping the angled clamping ends 1221 and 1222 to be moved with the
U-shaped plate 122 to one end at the parallel sliding openings 127
and 128. Before putting the master cellular phone 2 in the cellular
phone carrier board 60', the outer end 1212 of the lever 121 is
pulled with the hand in one direction to move the U-shaped plate
122 along the parallel sliding openings 127 and 128. After
installation of the master cellular phone 2, the lever 121 is
released from the hand and pulled back to its former position by
the tensile springs 124 and 125, enabling the angled clamping ends
1221 and 1222 of the U-shaped plate 122 to clamp on the master
cellular phone 2, and therefore the master cellular phone 2 is
firmly retained to the cellular phone carrier board 60' in
position.
[0031] As indicated above master cellular phone 2 is supported
above the cellular phone carrier board 60 or 60' of the mechanical
type auto dialing unit 20 or 20'. In order to let the sliding
button 74 be able to positively trigger the "OK" key button 5 of
the master cellular phone 2, the actuating bar 70 is arranged in
parallel to the master cellular phone 2, and the movable pressure
device 90 is arranged perpendicular to the actuating bar 70.
[0032] FIG. 12 shows another alternate form of the present
invention. According to this alternate form, the master cellular 2'
is coupled to an electronic type automatic dialing unit 130. The
electronic type automatic dialing unit 130 comprises a circuit
board 131, and a signal receiver 21 installed in the circuit board
131. The circuit board 131 comprises an electric plug 133, and an
output circuit 132 connected to the electric plug 133. The master
cellular phone 2' comprises a jack 7 at one lateral side wall
thereof, and a switching circuit 6 connected to the "OK" key button
5. When in use, the electric plug 133 is plugged into the jack 7 at
the master cellular phone 2'. When the signal receiver 21 receives
a warning signal from the warning signal transmitter unit 10, it
immediately drives the electronic type automatic dialing unit 130
to dial the master cellular phone 2', causing it to call the
telephone 3 or sub-cellular phone 4 (see also FIG. 1). The
electronic type automatic dialing unit 130 may obtain battery power
supply from the master cellular phone 2'. Alternatively, a battery
box (not shown) may be directly installed in the circuit board 131
to provide the necessary working voltage to the electronic type
automatic dialing unit 130.
[0033] FIGS. 13 and 14 show still another alternate form of the
present invention. According to this alternate form, an electronic
type automatic dialing unit 130' is built in the master cellular
phone 2". The electronic type automatic dialing unit 130' comprises
a circuit board 131', and a signal receiver 21 installed in the
circuit board 131'. The circuit board 131' is connected to a
switching circuit 6 at the "OK" key button 5 of the master cellular
phone 2". When the signal receiver 21 receives a warning signal
from the warning signal transmitter unit 10, it immediately drives
the circuit board 131' to switch on the "OK" button 5 twice,
thereby causing the master cellular phone 2" to call the telephone
3 or sub-cellular phone 4.
[0034] Because the mechanical type automatic dialing unit or
electronic type automatic dialing unit automatically dials a set
telephone number within a short time, a warning signal can be
quickly given to the assigned party when an emergency condition
occurs. Therefore, the assigned party can receive the signal before
the intruder damages the security system.
[0035] Because the security system of the present invention is
designed to be used with a commercially available cellular phone,
the use of the present invention must consider the characteristics
of commercially available cellular phone, i.e., before the
application of the present invention, the master cellular phone 2,
2' or 2" must be turned on and set into the mode for transferring
incoming call to another telephone, so as to prevent an
interference with the auto dialing function. Therefore, the master
cellular phone 2 is set in the mechanical type auto dialing unit 20
or 20'. If the master cellular phone 2' is used, it is coupled to
the electronic type auto dialing unit 130. Alternatively the master
cellular phone 2" may be used. When the mechanical type auto
dialing unit 20 or 20', or the electronic type auto dialing unit
130 or 130' receives a warning signal from the warning signal
transmitter unit 10, the master cellular phone 2, 2' or 2" is
immediately driven to achieve an auto dialing operation.
[0036] Further, either the mechanical type auto dialing unit 20 or
20', or the electronic type auto dialing unit 130 or 130' is used,
there is about 5 minutes of time delay when started, so that the
user has sufficient time to leave the place or equipment under
protection. The mechanical type auto dialing unit 20 or 20', or the
electronic type auto dialing unit 130 or 130' is set to start again
5 minutes after each triggering. Therefore, the master cellular
phone 2, 2' or 2" has sufficient time to complete circuit cutting
off operation and to further enter the stand-by mode if no body
picks up the master cellular phone 2, 2' or 2" upon an incoming
call.
[0037] Further, if the master cellular phone 2, 2' or 2" is set to
dial a cellular phone 4, the voice box function of the cellular
phone 4 is suggested to be turned off, so as to save the calling
charge. In case the cellular phone 4 is a voice-controlled cellular
phone, a particular sound is recorded in the master cellular phone
2, 2' or 2" in the warning message before, for example, the bark of
a dog, for switching on the cellular phone 4.
[0038] As indicated above, the mechanical type or electronic type
auto dialing unit according to the present invention can
automatically dial a cellular phone to call a particular number
when an abnormal condition occurs, so that the properly owner can
take the necessary step in time. Because the auto dialing function
is started by a radio warning signal, and the mechanical type or
electronic type auto dialing unit has self-provided battery power
supply, the master cellular phone and the mechanical type or
electronic type auto dialing unit can be received in a secret place
kept from sight. Because the master cellular phone can be triggered
to dial a particular telephone number within a short time after the
occurrence of an abnormal condition, the security system is
practical in use, and can positively inform the user of the
situation. Further, because the structure of the security system is
simple, the installation cost of the present invention is
inexpensive.
[0039] Further, we would like to explain why the OK key button of
the master cellular phone 2, 2' or 2" must be pressed or switched
on twice. Because we must preset a particular telephone number in
the said master cellular phone 2, 2' or 2" before we start to use
his security system, so, if we would like to dial the said
particular telephone number out through the said master cellular
phone 2, 2' or 2", we must press a particular key button for
reproducing that particular telephone number first. As we know,
some kinds of cellular phones can use a same key button, for
example, OK key button, to complete those two processes. So, if the
said master cellular phone 2, 2' or 2" wants to dial a set
particular telephone number out, it must let its OK key button be
pressed or switched on twice.
[0040] But, we also know that some other kinds of cellular phones
must use two different key buttons to complete those two processes
shown as above, i.e. they must use a first particular key button to
reproduce the said particular telephone number, then, use a second
particular key button to dial the said particular telephone number
out Maybe the said cellular phones are difficult to be used in
mechanical type auto dialing unit of the present application, but,
we believe that they could easily be used in electronic type auto
dialing unit of the present application.
[0041] Of course, we still know that there are some further kinds
of cellular phones which can complete those two processes by
pressing a particular key button once only. So, if we can let the
motor of the said mechanical type auto dialing unit rotate the said
cam one run only, then, the said cellular phones will be suitable
to be used in mechanical type auto dialing unit. Of course, they
could also be used in electronic type auto dialing unit.
[0042] Further, if the said master cellular phone 2, 2' or 2" is a
voice-controlled cellular phone, then, we can install a voice
player unit beside the said master cellular phone. Of course, the
said voice player unit can also play by a signal receiver.
Therefore, the said voice player unit will produce a special voice
to let the said master cellular phone dial a set telephone number
out after the said signal receiver received a warning signal from
an external warning signal transmitter means.
[0043] It is to be understood that the drawings are designed for
purposes of illustration only, and are not intended for use as a
definition of the limits and scope of the invention disclosed.
