Abstract

An electromagnetically operated (23) spring loaded (29) motor cut out (26) on a card (G) is contained within a tamperproof box (C) attached to a motor starter (A). The box (C) also contains on a card (F) a relay (20) which normally completes the key circuit but when set protectively activates the motor cut out (26) if any attempt is made to bridge the solenoid

Description

 The present invention relates to a device to prohibit the unauthorized use of a motor vehicle them: VL-PL-Batcaux-Engins etc ... using a starter ct by acting safe ct in it.

 Currently there are several systems and these are in fact only circuit breakers having efficiency only in this situation. Just locate the wires and make a bypass. The most sophisticated act directly and safely in the starter solenoid "Brcvct Mondial under ref .: WO 9114602 a 1 of March 10, 1991. This implies to transform and change it, which will have to be done in the factory. The new generation of starter does not have any more solenoid therefore this system is without happening.

 It would be easy to position a box at the input of the starter "or pass the PLUS battcric wire" in order to protect access to the interior and enclose a mechanism and electronics which would allow to let or prevent the current from switch to power and operation. It would be inviolable but imperatively placed at the entrance of each starter and for some it would be impossible given the positioning of this one "in general under the solenoid" especially since it would be quite imposing.

 To cut and restore contact you need large equipment and there is currently no miniature electronic component that serves as a relay for current up to 400 amps. In addition, the contacts should be quite large, see large, "the same ones that are in the solenoid" and deal with wear or the arc effect.

 On November 20, 1996 under the N 9514045, a French patent was filed, with our name making the same comments. This is what had pushed us to adopt another solution which consisted in acting on the PLUS and Less wires to inside said starter so that they are in contact at will by electronic control to cause a short circuit and render unusable said starter in the event of attempted theft.

 Experience has led us to choose another. less dangerous option for the user because there is a risk of provoking a fire in the vehicle (Plus and Minus in contact too long, melt the wires and bring a risk to the environment.

 The device according to the invention overcomes these drawbacks. Indeed inside all starters we find a PLUS wire and a MINUS wire. Lc PLUS is brought in via the solenoid and LEAST through the body of said starter when it is bolted to the motor (Massc) Ic, all coming from a 12 or 24 volt battery.

These wires feed coals which serve to rotate an electric coil when they are supplied and to make a starter usable.

 The first characteristic will be to intervene at the level of the wires which feed these coals. The intervention will be to separate Lc LESS from the starter body and using an extension lead it back outside of it after having caused a small passage (eg hole).

 For the supply needs of the system we will connect an electric wire to the PLUS and also bring it to the exterior. These two wires will be ready to be connected.

 The second characteristic will behave of a case cn acicr cemented ct inside which one will place a clectroniquc and a mechanism controlled and piloted either dircctcment or remotely by a nonlimiting electronic system. This box will include a hole which will allow a strand of electrical wires necessary to control the internal and protected electronics to pass through. Of these wires, two will be reserved, one will be connected to the wire coming from the ignition key command (ex: New man) the other will be connected to the solenoid to replace the existing one. The electronics and internal mechanism are called to be connected to the MINUS and PLUS wire at the output of the starter. The connection will be made by Ic below the tamper-resistant box (space provided for this purpose), and will be placed above the hole or other "starter outlet" so that access to these wires is impossible without dismantling the The housing will serve as MASS for the halter and place the starter before transformation.

 The third characteristic consists in cc that the electronic part sc located inside the tamper-evident case will have two cffets. The first, when the user of this system wants, using his command Ic to put in Active position (Put in anti-theft device) a relay will function in order to no longer allow current to flow at the level of the wire going towards the solenoid and make the ignition key inoperative. The second effect will be that the relay will be positioned so as to react the mechanical system if it is supplied with current in an unauthorized manner eg: Bridging (bring a PLUS).

Without an attempted theft, deactivating the system using its command will allow the relay to return to its initial position, ie to dirc before ACTIVATE Ic System.

 The last characteristic consists of the fact that once the system is in the Activated position if there is an attempt at fraudulent use (VOL bypass) the mechanism will react and will cause the internal coals of the starter to no longer be supplied by any source. dc current so that it can no longer function ct can not be used to start an engine.

According to particular embodiments:
- the integration, on the MINUS inside the starter, can also be done on the PLUS.

-The control system can be done either: by remote control, kind
Infra red, Ondcs, DTMF ctc key ... or dircctcmcnt by electronic key, keyboard with keys with personalized code etc ... it will suffice to adapt the internal electronics and can be done in manufacturing.

 -Lc acic case; case-hardened or in another material and of a variable thickness, but susccptiblc de Ic make inviolable, will include a hole either on one side or elsewhere according to the needs of manufacture and use.

 -The attachment of the case will not be soldering, tamper-proof bolting or other process capable of effectively resisting removal attempts.

 -The relay mentioned may be replaced by any other existing technique which will have the same characteristics and results.

 The system will react (to bridging) if a PLUS is added but will also react to the LEAST in the case of an option to act on the PLUS.

 The mechanism used is not limiting and may be adapted according to procedures existing on the market. For demonstration and explanation of the system we will use an electromagnet, a contactor with two positrons of which one maintained in pressed position, of copper or brass plates or other but good conductor of electricity of a rocking part in neutral material of a return spring for keeping the parts in contact.

With reference to these drawings, the starter A HG.:1 before transformation consists of several parts. The solenoid B with its connection pad: 5 receiving 4 which is the most from the battery D: the connection pad 7 with its wire 8 which goes inside the starter A and is connected to I which are the inductors: the pad 6 receiving the wire 3 from 1 the ignition key which once powered by 2 (Ic PLUS battery D) allows the pad 5 and 7 to be in contact and provide power (the PLUS) to the inductor I which then feeds via 9 the coal from the collector J .: E being the armature:
M being the General mass produced by the battery (LEAST or called Mass): 11 being the wire coming from the body part of the starter A: M being the mass, will feed the coal Less than J the collector.

 The starter A Fig .: 1 bis represents the transformation before the installation of the anti-theft box and which consists in that the wire 11 is detached from the starter block A therefore no longer being at Ground M: the wire 10 connected to the wire 9 which coming from the inductor I goes alongside 11 in a special sheath, outside the starter A thanks to a hole or other cavity made beforehand. The end of the wires 10 and 11 will be prepared so as to be easily connected to the anti-theft box. vs.

 The installation of the tamper-proof case: C: will be done on starter A not installed against the motor. Before sealing the box C on the starter A, proceed to connect 10 at the starter A outlet to 22 Fig: 2 bis which is positioned under the plate G (G being the mechanism support plate): 11 at the starter A outlet will be connected to 32 Fig: 2 bis of plate G. M (Ground) connected to box C by 33 will replace M (Ground of starter A Fig: 1 wire 11.

 .Case C once connected from below will be positioned above the starter hole or cavity A (la or pass 10 and 11) so as to cover them and protect them inaccessibly from the outside. This box will then be bolted (tamper-proof bolts) welded or other which will make it tamper-proof and will be earthed as it will form part with the starter A, outside, which is is due to its attachment to the engine.

 From this box To a strand of electric wires 14: exits through a hole (no matter where: side, above etc ... except below). From this strand of wires 14: the 1a will be fixed on the wire coming from the ignition key 1: the 2a will be positioned on the battery D at the pad 2, either directly or via an existing wire to the vehicle : the - LESS will be positioned on the battery D to M, or by means of an existing wire to the vehicle .: the 6 bis attaching to terminal 6 of the solenoid B: the 12 is intended for receiving electronic commands : 13 possibly being the electronic control: the 15 is on hold and can be used for the electronic part according to the mode used (DTMF key, keyboard with keys etc.) The number of wires of the strand 14 is not exhaustive and will be according to the modes of use of command and reception used in the present and in the future and not patentable and existing on the market. The box C being installed on A, the complete starter A is reassembled on the suitable motor and after connection of the wires comprising the strand 14, the anti-theft device will be operational.

 In normal use of starter A: the relay 20 of the electronic plate F in the housing C (Fig: 3) will be positioned so that the pad 18 receiving the wire 1 (ignition key) is in contact with the pad 19 receiving the wire coming from the stud 6 of the solenoid B: knowing that 27 of the plate G (mechanism) will be in contact with 28 thanks to 26 which joined them by the contraction of the spring 29: 25 being the lever arm called to be actuated by 23 (electromagnet magnet) and maintained by 24 (contactor). 32 connected to 27 by bolts 31 (electrically conductive) receiving 11 from starter A: 33 connected to 28 by 31 receiving wire M (General mass of starter A) This positioning will ensure that the ignition key 1 is usable for correct operation of starter A.

 ACTIVATE the anti-theft device by the user by means of its command (ex: 13 Fig: 2 bis) on the 12th receiving the message, will act on the relay 20 of the plate F and will ensure that the pad 18 is no longer in contact with the stud 19 and will have the effect of rendering the ignition key 1 inoperative because 6 of the solenoid B will no longer be supplied. 17 will be put on this occasion with 19:17 being the contact pad which will serve to trigger the mechanism if supplied following an attempted fraudulent use of the starter A (Bridging = addition of a PLUS wire from the Battery D ) The studs: 27 connected to 32 by 31 the stud 28 connected to 33 by 31, then the stud 26 held by the spring 29 will always be in contact.

DEACTIVATE the anti-theft device by the user by means of its command, 13 will cause the relay 20 to re-contact the pads 18 and 19 .: 17 being isolated. the studs of the mechanism
G remaining in their initial positions.

 If ATTEMPTED fraudulent use of starter A in the ACTIVATE position (anti-theft device), two possibilities: one would be to try to re-establish contact between 1 (ignition key) and 6 stud of solenoid B and to bring it a PLUS of the battery D so as to connect 5 to 7 of the solenoid B to supply the coals of J (collector) and turn the starter A. The other would be to supply directly 8 which enters the starter A with a wire more direct from battery D. This comes down to saying that there is a fraudulent bridging attempt.

 The system being in the SHAKE position, that is to say that the pad 17 of the relay 20 of the plate F (electronic) is in contact with the pad 19 therefore the addition of a Plus battery D by bridging will power it and will so that the electromagnet 23 is powered and actuated so as to attract the part 25 towards it and will have the effect of switching on 24 (contactor) which will end up in the pushed position and bring the part 30 into contact which will have effect of giving information to the electronic component 21 and its environment.

By pivoting this will drive the part 26 and maintain it (G fig: 4) thanks to 24 which will separate the stud 27 and 32 from the studs 28 and 33. therefore interrupt the supply of M (Ground) to the starter A. LE coal Mass of collector J no longer supplied with starter A will no longer be able to function.

 If no voluntary degradation of an unauthorized person has occurred, the user will use his command 13 to restore the situation and to be able to operate his starter A again. This operation will have the effect, thanks to the electronic component 21 and its environment, which will have been informed of the position of 30, to feed the electromagnet 23 again, which being attracted to it will again attract the moving part 25 dc so as to actuate again 24 (contactor) to take it out from its pushed-in position while detaching Ic contact 30. This in order to allow the parts 26 - 27 and 32 - 28 and 33- thanks to the return spring 29 to find themselves in contact therefore conductive. the relay 20 will also be actuated, which will have the effect of separating 17 from 19 and bringing 18 into contact with 19.

The realization and the manufacturing will be simple and can be expensive because mechanism, simple, and the on-board electronics will be of the CMS type (Surface Mounted Components) but could be different according to needs and intentions. The electronics and the Mechanism will be easily placed in the housing (places provided for this purpose) and will form
a set to be presented Ready to use (to be connected) and sold separately
of the starter.

The starter can be transformed at the factory in the Factory and put
in the market in two forms; one, in general, or the plus and minus wires
exterior will be bolted to the starter and allow buyers to
I 'anti-theft device, to place the box in this place. the other in a standard way with the wires
Plus and Minus out and ready to use and this will be found at resellers
of parts in standard exchange of the starter.

The starter can also be transformed by any specialist in
general mechanics or electricity. Once removed from the engine it will be opened and
transformed by adding more and less necessary wire. Installation of the housing and its fitting
will be easy (technical sheet attached) and the installer can either sell the box
anti-theft only, either with the starter (in standard exchange) or use the box
lock provided by his client.
