Abstract

The main purpose of this invention is only when the secret numbers are pressed, the engine is started and the locking equipment of steering axis and brake is released. In addition, in case that the driver must leave the car in the state of engine preheating of winter or in the state that the engine starting was made unavoidably, if one operates the secret number which corresponds to this function, one may not tread the accelerator pedal. If one treads the accelerator pedal, the engine starting is extinct. In that case, it is required that all the secret numbers must be pressed for the engine starting. But in the case that the starting is extinct due to the sudden detachment of clutch, there is no need to press the secret numbers again. Bonnet is also opened by the secret number. If one executes the whole of this invention, the key of automobile will not be necessary.

AUTOMOBILE IN WHICH THERE IS NOT KEY

BACKGROUND OF THE INVENTION Field of the invention

The purpose of this invention is for protecting the individual wealth from the theft of car and for preventing the trouble and cri¬ me used the stolen car. In addition, because key must be used in the present cars, one must carry the key or must hold it somewhere. And, there is frequently the case to be nervous by inserting the key in the car and locking the door outside. This invention made us get out of the above-mentioned inconvenience perfectly, by removing the key. If one use merely the circuit of the engine starting of this invention the key can be removed from the heavy equipments or the portable generators for outdoor which are started by battery.

Description of the Prior Art Today, various equipments for the theft prevention are selled in the market and attached at the time of manufacturing the car. nevertheless, the theft of car is endless, and most of the stolen cars are used for the crime. Most of the present safty devices are alarming sound system. These devices seem to have inconvenience wh- ich is apt to frighten surrounding people or prevent them from slee¬ ping at midnight. There is card-key and remote control system, but those devices also have the inconvenience to hold the key or remote control and one must always be careful not to lose it. There is se¬ cret number switch which can input the new secret number at one's will. This like device needs IC chip. When these system is out of order, experts are needed to repair. Also, there is danger to forg¬ et the newly inputed secret numbers frequently, because, mostly, he/she inclines to change them, if only those are easily changed.

SUMMARY OF THE INVENTION This invention succeeded in solving above-mentioned problems. Above all, only in case that one press the secret number, engine starting is made and bonnet is opened. If one starts the engine, the locking equipment of steering axis and brake gets to be released automatically. And, if one stops the engine starting, the steering axis and brake get to be locked automatically. The door for entrance and exit can be opened by secret number. That is, the operation is possible only the button, though the key bundle remove completely. If one does not know the secret number, nobody may operate anything» Especially, in this invention, specia- lly designed relay was used, so that the elementary driver may conf¬ irm the trouble easily. In addition, this invention does not trans¬ form the structure of existing car, and does not have influence on any voltage for starting at all.

For solving the problems of theft, let's examine the type of car theft, above all. First, When leaved the car, during the engine starting. Second, At the time when one parked the car on the road or in the alley at night, the case to steal by using the imitation key or by breaking^"the glass and invading the car and destorying the safty device. Third, The case to pull the car by using the rope and the other car. Fourth, The case to cut the locking equipment by mobilizing the cutting-off machine to steal. Fifth, The case to st¬ eal by using the traction car.

In this invention, it is impossible to steal the car, except the fourth and fifth among above theft methods. ^• Let's compare the five kinds of theft methods enumerated above with the composition of this invention. Among the above first theft method., if one operate the secret number, it is possible to tread the accelerator pedal. If only one treads the accelerator pedal, the engine starting is st¬ opped. Once the engine starting is stopped, the steering axis gets to be locked and brake is ready to be locked. And, only in case one press all six figures again, the starting is made. But, the case that the starting is stopped due to the sudden detachment of clutch during the driving is irrelevant to this function. Among the second theft method, though one invaded the car by taking any measures, it is impossible to start when one does not know the secret number.

And as far as the starting is made, the locking equipment of steeri¬ ng axis and brake is not released. These locking equipments are being equipped in the engine room. So, as far as one may not open the bonnet, one can not destory these. The secret number to open the bonnet is different from the secret number for starting.

So, it is the triple safty device. Among the third theft method, all the front and rear wheels are in the state that the brake is be¬ ing applied. So, car is not dragged at all. In case that one exec- cuted partially the circuit of this design in the car to use the key now, only first and second theft method may be prevented. But, in case one executed the whole of this invention, it removes the incon¬ venience to carry the key. It will do, if one memorizes only the secret number with ON-LINE type.

The designer of this invention designed it in the both sides of attack and defence. In addition, he designed it, so that the parts which are not complicated may be used to the minimum in the situati¬ on of mechanic. Thus, this invention is the new equipment for theft preventionin which the key is not necessary as what is different fr¬ om other kind of machine for theft prevention in the side of charac¬ ter and function.

The figure 1 is the starting circuit of gasoline engine to use the key(0) now. The figure 2 is the removing the key bundle(O) of the figure 1 and replaced it^'with the switch of button type, and composed the secret number(3) by intercepting the current to go to distributor(5) from the switch for the supply of primary power sour- ce(2) for starting over 5 times, and made the current apply to the distributor(5) by pressing the secret number(3) and contacting the intercepted part. Now, if only one press the starter(8) switch(7), the starting is made. Then, the secret number of six figures in all was composed, by intercepting the current to go to starter(8) over 1 time and composing the secret number(3). So as to heighten the saf¬ ty degree of locking function, the connection of release circuit wi- th the fifth switch among the secret number(3) was made. The reason why the primary current of starter(8) was intercepted only once is the sound that the starter(8) goes round brings the effect of alarm, in case the invader found out the number to operate the starter(δ) and operated this switch. As is shown in the figure 3, if only one press the secret number(3) in order, the current gets to be applied, if one press the switch of secret number 3-1, the relay 4-1 is oper¬ ated while the current passes through the relay 4'-l. And at the same time, the primary current of distributor(5) is contacted once. At this time, the power failure of relay 4'-2 is made. As the relay for.4' is for the power failure at the time of working, if one press the switch of secret number 3-2, the power failure is made at the relay 4'-2, and the electric current is sent by operating the relay 4-2 after passing through the relay 4'-3. The same principle is applied to the switch of secret number 3-4 also. Let's examine the case to mix the switch or press it reversely. If one press the switch of secret number 3-2 above all, the current operates 4*-l by passing through the relay 4'-2. Therefore, though one press the switch of secret number 3-1, as the relay may not pass over the relay 4'-l, the relay 4-1 is isolated. If one press rever- sely perfectly, Whole from the relay 4-1 to the relay to 4-4 is iso¬ lated by this principle. Thus, one must press the switch of secret number(3) in order. The figure 4 is the circuit of relay for sendi¬ ng an electric current, and figure 5 is the circuit of relay for power failure. Then, number 12 terminal is lighting bulb terminal, and the figure 6 is the circuit of relay for the combined use of sending an electric current and of power failure. When we see in the circuit of the figure 4, 5, and 6, the bulb of small-size(9) is being connected in series. Then this is for the use of overheat prevention at the time of working for long time. And, in case to use much quantity of relay at the automobile as the circuit of this design, this invention was designed especially, so that even the elementary driver may find out the parts which got out of order eas- ily. The relay is operated simultaneously with the lighting. The bulb of small-size(9) is about 0.3—0.5W. In the state that the starting was made, when one operated the secret number which corres¬ ponds to this, the figure 9 is the composition drawing that one may not tread the accelerator pedal. Then the micro switch(13) was used. To operate the secret number which corresponds to this function, the main current which flows to the switches(3) and relay(4, 4', 4") which are in the course of working now gets to flow by passing thro¬ ugh the micro switch(13). Therefore, to tread the accelerator pedal, the power failure of micro switch(13) is made. Thus, the current which used to flow to each switch(3) and each relay(4, 4', 4") gets to be intercepted at the same time. So, the starting gets to be stopped, and at the same time, the locking equipment of steering ax¬ is gets to be locked and the brake is ready to be locked by the ope¬ ration. (Refer to the figure 23). To explain will be made with the figure 10. The secret number for starting is 123456, the secret nu¬ mber for one may not accelerator pedal is 9, 7. The circuit of the figure 10 is the circuit that the starting was made, and it is the circuit that secret number 9,7 was operated. The power source which came out from starter(δ) switch(7) comes into COM terminal of 3-9 which are the switch of secret number, and then it enters NO termin¬ al of micro switch(13) by passing through NO terminal. And then, it comes out to COM terminal again gets to flow to each switch of secret number(3-l—3-0). To tread the accelerator pedal, the power failure of micro switch(13) is made. So the power failure of each switch of secret number(3-l—3-0) and each relay is made simultane¬ ously. Thus, all the currents from the relay 4'-l to 4-6 are cut OFF. So the starting is stopped. To leave the accelerator pedal again, the relays may beoperated as the circuit of starting state. But, as the result of experiment, since the decision is made accord¬ ing as any relay is operated first by the number of wired numbers of coil of relay, one must control the number of wired times of coil, so that the erlay 4'-l which is the odd number of relay may be oper- ated first. In the relays, 4'-11 is the service relay to make the starter(8) fail to be operated. Though the starting is not made be¬ cause the relay 4'-l is operated first among the relays. Thus, in the relay 4-5, the power failure of the current to go to distributor (5) is made. So the locking equipment is not released. (Refer to to the figure 23). When one operates the corresponding secret numbers 9 and 7, one must press 9 first, and then one must press 7. And, when one releases one must release, by pressing 7 reversely first and pressing 9. Let's examine the circuit that 3-9 and 3-7 which are the switches of secret number were released. As the power sour- ce which came out from the starter(δ) switch(7) comes into COM term¬ inal of 3-9 which is the switch of secret number and then comes out from NOC terminal and then it is applied to COM terminal of micro switch(13), it is irrelevant to micro switch(13) in the course of operation. So the power source is supplied normally. Therefore, at the time of working reservation of protection function of starting state, if one press the switches of secret number, the starting gets to be stopped. In the figure 10, if one press the 3-8 switch are the switches of secret number, as the relay 4'-11 gets to be operat¬ ed, the starter(δ) is not operated. This function protects the sta- rter(8), and may prevent the trouble of safty carelessness at the time of maintenance of simple engine.

2. Circuit of Locking Equipment of Bonnet

The locking equipment of bonnet is the first important part in the theft prevention of car. In the aspect for operation, the star- ting equipment is important. But, for the theft prevention at the time of parking, bonnet is the most important. Because, if anybody may open the bonnet at his option, anybody may start by disregarding the whole of wiring installed in engine and binding the straight li¬ ne with some pieces of wiring. The figure 11 is the conposition drawing of equipment to open the bonnet to be used now. Then, as is shown in the figure 12, the han¬ dle installed outside(lδ) was removed, and the open magnet(18') was replaced instead of handle(lδ), and the open magnet^β*) was equipm¬ ent and attached in the engine room, and the open magnet(lδ') gets to be operated only by means of secret number by using the basic ci¬ rcuit of the figure 3. Thus, if one does not know the secret number, he/she may not open the bonnet. The figure 13 is a circuit of magn¬ et. As is shown in the figure 14, the secret number to open the bo¬ nnet is 123456. Then, the plus(+) current of open magnet(lδ') was intercepted over 6 times. To press the switch 3-6 which are the last numbers among the secret number, the open magnet(lδ') is opera- ted and the locking ring(20) gets to be opened. At this time, minus (-) current of open magnet(lδ') flows to the relay 4'-11. The relay 4'-11 of the figure 10 is the service relay to protect the starter(δ) , but it is the relay for the interception of power source of each switch(3-l—3-0) and each relay(4, 4') in the locking circuit. In the figure 14, at the moment that the open magnet(18') is operat¬ ed, while the minus(-) current flows to the relay 4'-11, 4'-ll is operated. Thus, the main current of the secret number switch(3) and the relay(4, 4') is intercepted momentarily. And at the moment that the main current of relay 4'-11 flows again, as relay 4'-l is opera- ted first, the current of relay 4-1 is intercepted. Therefore, open magnet(18') gets to rest after operating only the locking ring(20). This circuit is protected open magnet(lδ').

3. Circuit of Make and Break of the Door for Entrance and Exit

By removing the key, as is shown in the figure 16e, in the door for entrance and exit also, this circuit was connected with the equ¬ ipment of the automatic make and break of the door for entrance and exit to be used only in over medium-sized car now by using the circ¬ uit of this design. In this equipment, the emergency jack to be able to use the power source after borrowing it from outside was in- stalled, by providing for the time when one may not open the door due to the case of sudden battery discharge and due to the contact inferiority of battery terminal. In locking the door, one press the locking button(24') only. Figure 16e is the circuit added relay(4'") to the basic circuit. The reason is the switch of the door inclines to be frozen by snow or rain in the cold winter. So, it will be go¬ od to use the tact switch(3') as the secret number switch of the door. Next is the explanation about operation above mentioned; the figure 16d is the state of door locked, so the main switch(l') is ON. Only to press the secret number switch(3'), at the same time, an electric current is applied to the relay 4"', and the consequence of being operated the relay 4 ^I, an electric current is applied to the relay 4¹, as an electric current flows in the coils of the relay 4'", although one take his hand off the secret number switch(3'), the operation of the relay 4"¹ is continued. If one open the door, the main switch(l') is turned OFF, an electric current which flows the relay 4^f" and the relay 4¹ should be intercepted. In the figure 16e, the secret number for openning the door is 1234. As the secret number switches stand out of the car, the electric source wire(25') which applies the current to the magnet for the release of the lock¬ ing function of the door for entrance and exit must be connected wi¬ th this magnet directly through mere the main switch(l') of the door. In the trunk and in the cap of the hole to infuse fuel, key is not necessary. Because the operation is inside in the car.

4. Locking Equipment of Steering Axis

This invention was designed especially, so that the locking eq¬ uipment of steering axis may not be destoryed before opening the bo- nnet by installing it in the engine room. As is shown in the figure 17, this is the equipment to paralyze the operation of steering axis (34) by means of the insertion of locking pin(33) into intaglio gro- ove(35), by forming the intaglio groove(35) in the steering axis. As the make and break of this equipment is being connected with the starting circuit of the figure 10, if one operate the secret number (3) so as to start, release is made automatically. And, if one sto¬ ps the starting, it is locked automatically. It is important in th¬ is function, when one stops the engine, he/she should use the secret number switch(3) to be locked the steering axis and the brake locki- ng equipment. When one test the state of steering axis and brake locking equipment, must use main switch(l) not to be worked the loc¬ king equipment of the steering axis and brake. The brake locking equipment will be explained by next part of No. 5. The composition drawing of the figure 17 will be explained in parallel with the fig- ure 23. In the figure 23, the most important thing is switch 3.

If the relay 4"-l is abruptly out of order in driving, steering axis and brake are locked. So, the switch 3 is added, therefore the switch should be off in driving. Because the locking system will not work, even if the relay 4"-l shall be out of order. The figure 17 is in the locked state. Then this explanation is the course for release. As the relay 4-5 is operated simultaneously wi- th pressing 3-5 which is the fifth switch among the secret numbers for starting, the power source is applied to the open magnet(lδ') after passing through the operator(3δ') of the switch for magnet protection(36). And then, while the open magnet(18') is operated, the lower half moon key(28) of the figure 17 points downward. At this time, upper half moon key(29) returns to the original position by the center point(30) and return spring(41). And, at the same ti¬ me, while the cylinder for locking(32) falls into the left, the ste¬ ering axis(34) is released. Simultaneously with this, the operator (38') of the switch for magnet protection is turned OFF, while the outside sensor(3δ) falls into the intaglio groove(37) of the cylind¬ er for locking. Thus, the open magnet(18') release only the steeri¬ ng axis(34), and it gets to rest as the power source is intercepted at the protection switch. At this time, the protection switch(36') of locking magnet(18^M) is turned ON again. If one releases 3-1 which is the switch of secret number, engine stops, and the power source flows from the relay 4"-l to locking magnet(18") through the protection switch(36'). Thus, the steering axis gets to be locked. And, at the same time, the protection switch(36') of locking magnet (18") is turned OFF again, and the protection switch(36) of open magnet(lδ') is turned ON again.

The board for projection control(51) of operation part of each magnet is for preventing that the connection ring(52) is projected over necessity. The figure 18 is the composition elevation of the figure 17. Then, the explanation is as follows: The composition is devided into upper part and lower part largely. Then, the lower half moon key(28) prevents the projection over necessity, as the bo¬ ard for projection interception(31') is hung on the pin for the con¬ trol of operation gap(42). And, it gets to return to the original position, after the operation by the return spring(41). The extens- ion body below the lower half moon key(28) was fixed with the tight¬ ening bolt(40) by being shielded with bushing(39") and covering with the cover(39), so as to make the operation smooth as the round cyli¬ ndrical form. In the upper part, the cylinder for locking(32) and the locking pin(33) are main composition parts. Then, so as the intercept the projection over necessity at the time of make and bre¬ ak the gap jaw(31) was formed. And, for the disassembly and assemb¬ ly of parts inside the cylinder(32), the intaglio installation of cutting part(43) was made. Upper half moon key(29) returns to the original position by the return spring(41), after being fixed at the fixation pin of center(30). And, the extension body(46) of locking rod is being fixed fixed by the fixation pin(44). And, in the upper half moon key(29), as the operation of half moon part is stopped to- ward the upper direction to 45 degree of right side by the center point(30) at the time of release, the intaglio installation of oper¬ ation gap groove(45) was made. At the upper part of 'the cylinder for locking(32), sending an electric current and power failure of the power source of magnet(18' , 18") can be made, by .forming the intaglio groove(37). To supplement and explain in the figure 17 is as follows: Filling the lubricant(27) to the full inside the chass¬ is of locking equipment(26) made the contact part of each part oper¬ ate smoothly, and covering the part to be projected outside the cha- ssis(26) with the cover into which oil ring(4δ) was -inserted and fixing it with bolt(50) prevented the oil leakage, and the chassis cover(26^r) was fixed with bolt(50) by making many units of bolt hol- es(50'). As the cylinder for locking(32) and the locking pin(33) are operated simultaneously, they were made, so that the locking pin {33) may be inserted into the intaglio groove(35) of steering axis (34), after penetrating the pipe(51) to protect steering axis(34). When we see in the figure 20, so as to prevent that the cylinder for locking(32) is destoryed by the force of inertia by putting str¬ ess on the handle compulsorily and turning it suddenly, the part on which the locking pin(33) is hung which is inside the cylinder for locking(32) was thickened, when we see in the figure 23, the manual release equipment(lδ) was installed by providing for the time of trouble of circuit. Of course, this equipment is being installed in the engine room.

5. Locking Equipment of Brake The figure 24 is the composition drawing of locking equipment of brake. The composition of parts is same as the locking equipment of steering axis, and the different point is that the brake rod(56) and the locking pin of saw tooth(5δ) are being installed specially. As for the operation of brake of oil pressure type, to tread the pedal(54), the rod(56) which is being connected with pedal(54) oper¬ ates the master cylinder(59), and then the brake fluid is sent to the pipe(59'). Thus, the brake gets to be applied. Then, in this invention, the separation of pedal(54) and rod(56) made the contact part(55) indipendent. As is seen in the figure 24, newly designed locking equipment is being installed in the engine room of the sepa¬ ration room(53) of driving seat and engine room. As far as one may not open the bonnet, this may not be destoryed. The explanation is as follows: The connection circuit of this locking equipment is as same as the figure 23. Thus, if one stops the starting, the cylind¬ er for locking(32) is projected to the upper part. After this, to tread the brake, the tooth for locking(5δ) gets to be geared with pin(33'). Thus, pedal(54) gets to return to the original position by the return spring(41), and the brake is being applied. So, all the front and rear wheels become the locking state. If one does not tread the brake after stopping the starting, the locking pin(33') is only in the waiting state. In this composition, the pressure of return spring(41) of brake pedal(54) and that of return spring(41) of rod(56) must be same to the minimum, or the pressure of return spring(41) of rod(56) must be high a little bit. Connecting the rod(56) with nut made the disassembly and assembly of saw tooth(5δ) smooth. At the time of emergency, the installation of manual relea- se equipment(lδ) provided for the time of circuit trouble. To start, the open magnet(lδ') is operated. Thus, the cylinder for locking(32) is released and points downward. So, it does not have influence on the brake operation at all at the time of traveling. The upper part of the saw tooth for locking(5δ) was made, so that the protection switch(36, 36') amy be positioned, by forming the intaglio groove (37') of which the length is long. This is because the protection switch(36') must maintain the operation state continuously, though the saw tooth(58) is geared depply. In addition, in the locking eq¬ uipment of steering axis and brake, to release the switch of secret number 3-1, the locking state is made, as the locking equipment is operated. But, turn OFF the main switch(l) than the switch of secr¬ et number, 3-1 above all, the locking equipment is not operated. If one tries to lock the steering axis and brake, one must turn OFF the main switch(l), after the locking equipment gets to be operated, by releasing the switch of secret number, 3-1 above all. At the time of maintenance and inspection of steering axis and brake, the locking state must not be made. So, in case of this maintenance and inspection, if one turn OFF the main switch(l) above all, the engine is stopped, and the locking equipment is not operated.

6. Equipment of the Make and Break of the Fuel of Diesel Engine

The figure 2δ is the equipment of the make and break of the fu¬ el of diesel engine. In the diesel engine, it will do, if only one make and break the cock(63) to intercept the fuel of governor(61) of injection pump(60) by using the circuit of this invention, as the starting is stopped only in case the fuel is intercepted differently from the benzine, the explanation is as follows: As is seen in the figure 2δ, the upper half moon key(29) which is the locking equipment of design was installed in the cock(63) to intercept the fuel of governor(61). As the figure 28 is in the sta¬ te that the starting was stopped, the fuel supply to the pipe to se¬ nd fuel is stopped. At the end part of locking magnet(18^π), the switch of magnet protection(36) was installed. The figure 29 is the connection drawing of magnet of gasoline engine. The explanation is as follows: To press the switch of secret number, 3-5, the relay 4-5 is connected. Thus, the open magnet(lδ') is operated. Simulta¬ neously with this, while the minus(-) current of open magnet(lδ') flows to the relay 4'-12, 4'-12 is operated, and the power source of each switch(3-l—3-0) and each relay(4, 4¹, 4") is intercepted. The current of any one part among the interception part of 5 times of plus(+) current of open magnet(lδ') gets to be cut. So, the open magnet(18') gets to be rest. This principle is same as the circuit of bonnet open. The reason why the plus(+) current was intercepted is for connecting the locking equipment of steering axis and brake. If the open magnet(lδ') is operated, the operator (38) of the switch of magnet protection(36) is turned ON, and the locking magnet(18") becomes the waiting state. At the time of engine stop, to press the engine stop button(64), locking magnet(18") is operated, and the starting gets to be stopped, and the switch of magnet protection is turned OFF again. Thus, the button of engine stop(64) is not opera¬ ted. And, only in case the starting state is made, operation is made. The following is the explanation of the circuit of protection function of starting atste. The figure 29 is the circuit that the starting was made. Then, the secret number of this circuit is 1234 56, and the secret number of starting state is 079. Among 079, 0 is the number that even any one among the switches from 3-1 and 3-6 may not be touched, and 7, 9 are the number that the accelerator pedal may not be trodden. In operating this function, one must press 7, and then must press 9. To press 9 above all operate the locking magnet(18") immediately, as the switch of secret number, 3-7 is bei- ng circulated to N0C terminal, that is, it is on the off state. To press the switch 7, and then press 9, the current flows the COM terminal of micro switch(13). To tread the accelerator pedal, as the current flows the N0C terminal of micro switch(13), locking mag- net(18") is operated, and. the starting gets to be stopped. On the contrary, at the time of number release, reverse order must be made. One must release, by pressing 9 above all and then 7. Switch 0 is irrelevant to treading the accelerator pedal, but it is for prevent¬ ing that the invader presses any numbers so as to find out the secr¬ et number of starting state. The reason why the current which came out from micro switch(13) was connected with COM terminal of the switch of magnet protection(36) is turned OFF, if the starting is stopped, in assuming that the starting was stopped by the touch of the switch of secret number, 3-2 of invader. The figure 30 is the circuit of totalexecution of diesel engine. Then, as the connection circuit of locking equipment of steering axis and brake is same as the connection circuit of benzine car, omission was made in the fig¬ ure 30.

7. Locking Equipment of Steering Axis and Brake During the Engine Running The figure 31 is the circuit that steering axis and brake can be locked at a state of engine started. All circuits mentioned abo¬ ve show that both the steering axis and the brake are not locked during the engine running. So, though the door for enterance and exit be locked, provided he/she do not touch the accelerator pedal, can operate steering wheel and steal the car by using of another traction car. The purpose of this circuit is to prevent it. The explanation is as follows: Being the state of engine stopped, from the relay 4"-l to 4-5 and 4'" do not work. In order to start, the switch of secret number 3-1 and 3-5 should be pushed, then current flows through the relay 4^,,r and protection switch of open magnet(36) and operates the open magnet(lδ') and then locking state is released. (Refer to the figure 23). Being the state of engine starting, if one push the locking switch(66(3')) the locking magnet(18") is worked, then the protecti¬ on switch of locking magnet(36') is turned OFF, and the protection switch of open magnet(36) is turned ON again. At the same time, the relay 4'" is worked and because of the current which flows to the protection switch of open magnet(36) is intercepted, the open magnet(lδ') is not worked. To release the locking equipment, make main switch(l) turn OFF and ON and then press the secret number aga¬ in. And it is released. As what was explained above, because this invention does not transform the structure of car which is being ma¬ nufactured now and may obtain the maximum effect by attaching simply, the person concerned who areemployed in the automobile field and the drivers who drive the car will have sympathy. I am convinced that this will bring the considerable effect for protecting the individu- al fortune and for preventing the crime from the endless car theft.
