DESCRIPTION

ELECTRO-MECHANICAL ARMORED STEERING LOCK DEVICE A

ELECTRONIC CONTROL A

CUSTOM CODED CHIN,

PRIOR STATE OF THE ART

Axial sliding locks are used to engage a pin in a hole and to lock its position. Examples of application of such devices are available; in the construction of closing mechanisms for safes or those that block the steering of motor vehicles, boats, etc., the manufacturers of these mechanisms have long been engaged in the search for a solution that is suitable for preventing burglary that cannot be closed with maneuvers involuntary and that it is always reliable for a very high number of activation and deactivation cides.

All the devices consist of a sliding pin, fitted with a lock, which; engages in a hole made in a moving part, such as, for example, in the steering column of a motor vehicle or in an additional perforated bushing applied to it

Furthermore, all the devices are equipped, inside the fixed casing, with two grooves suitable for containing the elements (cams or pullers) for locking the pin in the two engaged and disengaged positions. An evolution of this device consisted in the application of a cam on the rotation axis of the lock which radially pushes some magnetic cylinders into the groove made inside the fixed casing, OBJECTIVE THAT THE INNOVATION INTENDS TO REACH new steering lock differs from all the others on the market, as the anti-theft device is activated by a micromotor, which represents the real novelty of this device.

For this anti-theft, two possible application solutions have been envisaged, which are completely interchangeable with each other, so as to allow maximum flexibility for construction and commercial needs. (See the overall drawings attached COM 0384 and COM 0383).

! components that make up the alarm in both solutions are practically the same except in the control of the alarm activation.

In the first solution dis. COM 0384}, the device consists mainly of a mobile casing (2) and a fixed casing (I). Inside the mobile casing there is keyed a micromotor that drives the movement. The impulse to the micromotor, and therefore to the alarm, can be given by different types of systems using an electronic control unit. all interchangeable, chosen according to customer satisfaction:

Remote controller;

Coded electronic key;

Encoded card;

Numeric keypad;

Finger prints (fingerprints);

identification of the iris;

Optical reader.

On the sides of the mobile casing there are two slots, placed diametrically opposite each other. where the two '' puller '' cams (5) are housed inside which, activated by the rotor end of the lock, protrude or re-enter the mobile casing. Given the diametrically opposite arrangement of the two cams, the mobile lock casing block is protected from break-ins on the entire 360 ° angle. :

To close the movable casing, there are a reaction disk (7), an elastic ring (X), a very truncated cone (9), a locking piston formed by a pin (10) and; from a disc (I I); and finally another elastic ring and another very truncated cone completely identical to the two listed above.

The reaction disk has a double function: that of guiding the two pullers in sliding, and of reacting to the normal force given by the clastic force of the spring (9) and by the locking pin (10).

The first truncated conical spring, placed between the reaction disk and the locking pin, has the function of contracting when we insert the alarm and then, with its elastic force, to extend when the steering wheel is turned, thus engaging the locking piston in the hole in the bushing located on the rotation axis of the steering column. This type of actuation of the steering lock is called "Automatic", which means that it allows the insertion of the anti-theft steering lock in any position the steering is located.

a second truncated conical spring, placed at the end of the mobile casing around the piston, has the function of pushing the movable casing out of the fixed casing when the alarm is disarmed.

Finally, between the mobile casing and the fixed casing there is a magnetic sensor to which all the electrical part with which the device can be equipped is connected, including an electronic anti-start system. This system complies with the Ministerial Decree of Γ 11/03/97 on directive 95/96 / EC according to which all motor vehicles equipped with unauthorized devices must be equipped with protective devices. This starter system consists of an electronic control unit and a visual indicator (LED). The control unit inhibits the starting of the engine in the event of the steering lock engaged. steering lock: when the steering lock is on, the LED is red; when the device is disconnected, the LED is green and therefore the vehicle is ready to be switched on.

Furthermore, all this is accompanied by a series of electronic devices that further increase the safety coefficient of the burglar alarm, always at the discretion of the customer, such as:

Ultrasonic or proximity photocell;

Anti-leveling device;

GPS or GSM interface;

Anti-theft

Pager;

Acustic signal.

HOW THE BURGLAR ALARM WORKS

The alarm is activated when the user, by pressing a finger on the face of the mobile casing, in any position the steering wheel is in, pushes the mobile part of the device towards the steering column, thus overcoming the elastic force of the: two many truncated cones. Λ this point the micromotor comes into action which pushes the two pull-out cams outside the mobile casing which enter the groove located at the end of the stroke, inside the fixed casing, thus allowing the casing to be anchored movable to the fixed casing in a pen-like manner until the next voluntary disconnection by the user. At this point, as previously described, the frustoconical spring placed in front of the pi

stone contracts; The user rotates the steering and the spring is released by pushing the piston towards the hole in the bushing located on the steering axis. The steering is locked.

To disarm the alarm, simply touch the sensor: this simple operation allows the system to recognize the owner's card and send the signal to the electronic control unit of the micromotor. The latter, returning to the starting position, returns the two pull cams and thus unlocks the mobile part of the alarm. It will then be the force of gravity, but above all the elastic force, to bring the alarm into the disarmed state.

In the rest state, the two puller cams come out again from the mobile casing, inserting themselves into another groove placed inside the fixed casing, thus ensuring the locking which serves to avoid accidental insertions by the user.

As described above, the first solution (dis. COM 0383) differs from the second solution (dis. COM 0384) only in the type of pull-out cam release mechanism,

In the drawing COM 0383 the puller cams slide thanks to their particular shape. operated by a small cam placed on the micromotor shaft; while in the drawing COM 0384 the system works thanks to the pinion-rack principle which transforms a rotary motion into a translational motion: the two cams have the rack in their own shape, and a small toothed wheel is placed on the micromotor shaft to generate its movement .

In drawings COM 0382 and COM 0284 the device shown above is represented;

the difference consists in the activation of the alarm, given by a European cylinder lock, rather than by the micromotor.

The lock replaces the function of the micromotor, thus further increasing the flexibility of the project, responding to the needs of the market.

The high security European cylinder lock (5), equipped with coded keys and accompanied by a personalized card with alphanumeric code, offers total protection against fraudulent duplication; (The key can be duplicated directly or in authorized centers by showing the lock card and identity document. In front of the lock there is a protection pawl called defender (3). It protects the lock from break-in attempts , such as fun, and trepanation. being built with an anti-drill sintered steel, the slot of the same allows only the key to be able to enter.

Between the pull cams and the lock there is a spiral spring (9) which allows the lock of the device to return with the elastic groove of the same, to the position of "0 <"> (i.e. the key comes out),

the operation of the alarm, with the lock, is the same as previously described and differs only in the actuation, given by the user's hand.

All the electronic devices described on page 4 are equally applicable to the device with lock
