Description

[Detailed description of the invention] Safety device with key or card The present invention is a cord-locked high security device that looks like a type of operation panel or operation block. For all equipment, signals or commands from it may be transmitted to building doors, windows, shutters and in the field of safes or any mechanical, electrical or even digital devices. One or more locks or electric motors that cause locking or unlocking of the part to be protected. or other drive device.

The invention therefore applies to the field of electrical or electronic equipment. In this case one The invention relates to locking or unlocking mechanical parts such as levers, keys etc. Interrupts electrical or electronic circuits that prevent intrusion into computer or terminal programs can. The invention is also well applicable to other fields such as telephones, watches, cameras etc. .

Although sufficient safety is guaranteed by itself, this device can be alarms, monitoring devices, programmed clocks, or even to deter intruders. Can be combined with devices that can be neutralized.

More specifically, the present invention is disclosed in French Patent of Addition No. 8316313/21551. Previous French Patent No. 8301496 in the name of the applicant supplemented by No. 39 / 2539795, which includes doors, windows and similar Similar closing and opening safety devices have already been described, each with a key It has a grid with a plurality of holes or windows suitable for receiving. Small holes or windows At least one is combined with sensing means for insertion of a suitable key and commands for locking/unlocking. means, while all other holes or windows in the grid are connected to such means. Lacking. Holes or windows other than holes or windows for effective commands to open/close or lock/unlock At least one part is combined with sensing means for insertion of something and connected with alarm means. ing. Reference is also made to the corresponding European Patent No. 0116001 in the name of the applicant. Good morning.

When it comes to such security devices, it is important not only to have the appropriate key, but also to must be inserted into the correct hole and in the correct direction, otherwise all other In all cases, it is impossible to open/close/lock/unlock the protective part. did Therefore, the larger the number of holes or windows, the more likely they are to operate before being commanded by the device. It is understood that there will be fewer opportunities to meet the risks.

Furthermore, by inserting objects (even the same as the correct "key") into every hole in the grid one after another. Thus, in order to make attempts to destroy the device even more difficult, said sensing means may be In the event of such an operation, an alarm and possibly other protective actions shall be triggered. Make it.

The above-mentioned literature is 1 wrong as an edible supplement.

It also predicts electrical contacts actuated by valves that normally close the entrances of all holes, These contacts are in addition to other electrical contacts inside, and all contacts are connected to the electrical circuit that reaches the alarm. located on the road. A valve is also an object by which the device is intended to be destroyed. The alarm will be activated regardless of the shape and depth of insertion.

Furthermore, for one or each correct “hole” (or one’ correct “window”) in the grid. The above works by inserting a suitable key into this hole (or window). It predicts electrical contacts or electrical fixed contacts suitable for

Given this state of the art, the present patent application is designed to make devices of the type at issue here safe. By giving the valve additional new features, especially in terms of performance and reliability, and also electrical Further improvements can be made by providing sensing means other than fixed contacts or electrical contacts. This is what we are trying to do.

The invention therefore provides a plurality of holes and/or holes, each suitable for receiving a key or a card. or a window, at least one of the holes and/or windows being suitable for insertion of a suitable key or card. It is combined with a sensing means for opening/closing or locking/unlocking. , other holes or windows may lack such means, but are preferably provided with alarm means and and/or connected to disabling means of the opening/closing or locking/unlocking system and coupled to electrical means. Further valves are provided at all hole or window inlets to prevent alarms and/or devices. Has a key or card, or has a key and a card, which can also be connected to a disabling means With respect to the safety device, the said valves are activated by the sequential activation of these valves. In combination with the identification means of the code thus emitted, the opening/closing or It is characterized in that it is provided for the purpose of giving approval to locking/unlocking commands.

So the valve here is useful for programming one kind of code, like this Only after carrying out preliminary coding operations can the correct hole or window be "Insertion of a key or card would be effective in causing opening or unlocking of the device" If the alarm and/or device override will be activated, the override will be It is triggered immediately from the first false contact.

Guaranteed control by valve actuation determined by programmed sequence. Key-specific “combinations” and overall security have been increased even more significantly, but Only one or a few holes are "correct" to provide a very high level of safety. It will be appreciated that in addition to the fact that Possession of a key and even accidental knowledge of one or a few correct holes may lead to opening/closing or operation. Unable to obtain lock/unlock operation. Is it the basic principle of a lattice with more holes? Therefore, the overall safety of the device is compromised by the fact that the increase in holes naturally increases the size of the valves and therefore these valves. Therefore, the number of holes increases as the number of coded combinations realized increases. It will probably get bigger.

Additionally, these entire valves must be inspected by the authorized user of the device for personal identification upon first use of the device. Program code and, in some cases, improve production without compromising safety. This leads to simplicity and economy, especially when the keys themselves are individualized to avoid a large number of keys for users. If humanization is not possible, the code can be modified at a later date.

The valves work together to form a cord.

It retains the individual ability to monitor the insertion of something into the hole or window. Therefore Said valves must be activated by the actuation of these valves in the desired sequence and then by the authorized user. Yoru re! ! Insertion of the key or card into the 'correct' hole or 'correct' window for identification The code can be formed in such a way that it does not cause accidental alarms or invalidations. The alarm and/or override may be configured to operate only after a certain amount of time, so that Advantageously, it is combined with delayed delay means.

According to another aspect of the invention, the device includes one or more holes, notches, etc. at least one key or card, while one or more correct "holes" or 1'The correct" window has an arrangement that corresponds to the arrangement of the holes or notches on the key or card. The light emitting means is equipped with a light emitting means such as a light beam and a light receiving means, for example, a discharge light emitting diode. electrical contacts and eliminates the risk of wear and failure caused by previously used electrical contacts. The set allows optical recognition of the correct key or card.

The emitter and receiver were placed behind the entrance of the hole or window. key or card is preferably arranged in a preferably tubular guide for receiving the There are at least one sensing means for compensating the electrical supply from said emitter and receiver. The sensing means itself is activated by inserting a key or card into the hole or window. be done. Therefore, the supply from the emitter and photoelectric receiver is not constant, and the current is Flows in these components and in circuits to which they are connected only during authorized use of the equipment. This leads to a significant reduction in the power consumption by the device, and it reduce the importance of separate power sources, such as batteries, refillable or otherwise; be able to.

The advantage of the invention is the simplification of the keys or cards belonging to the device, but with certain features. The advantages of such keys can be demonstrated in a variety of applications. Special configurations such as: can be adopted.

- a predetermined relative position (angular position and/or axial medial position II); a double key consisting of a retractable hollow outer element and an inner element; - Rotating head to avoid visibility of the correct angular position of insertion by anyone other than the authorized user; A key with a preferably cylindrical shaft.

In the case of valves that move laterally by movement towards the inside of the corresponding hole or window, the code The actuation of these valves for oxidation is caused by the key or card itself being pushed towards the entrance of the hole or window. Therefore, it should be noted that it can be easily carried out; in any case, the present invention does not limit Some embodiments of the present security device are illustrated with a key or card as an example without It will be better understood by the description made below with reference to the accompanying figures. cormorant.

The safety device shown in the figure has a visible part that can be accessed from the outside for its operation. 1], rectangular as shown in the figure, or circular as shown in figure 2, It has a grid 1 that can take any shape.

Lattice 1 attaches to an object, such as a door, in order to open or unlock the object. or placed at a fixed position close to or distant from the object. This grid 1 , a number of holes or windows 2.3 arranged in a grid pattern or other arrangement. 1st , the figure shows by way of example a circular hole 2 suitable for receiving a key with a preferably cylindrical shaft. , 3, and FIG. 4 shows a "card" which constitutes the same thing as the key. 2 shows elongated windows 2, 3 suitable for receiving portable flat elements called ``portable flat elements''. key or The combinations of holes and windows that are likely to accept cards can also be predicted.

For instructions on the use of the device, a key or card must be placed there, known to the usual user. Correct insertion of the card will cause or permit the opening/closing or locking/unlocking action. One or more holes or windows 2 are distinguished.

Other holes or windows 3 may not contain any objects or the correct key or card, except in special cases. It cannot be opened/closed or locked/unlocked even if the same item as the card is inserted. these holes or windows The internal structure regarding 2.3 will be described later.

According to an essential aspect of the invention, the holes or windows 2.3 of the grid 1 are particularly circular on their entrance side. with movably mounted valves 4 or similar means, which in their normal position are This closes two-thirds of the holes or windows.

Valve 4 is provided here for programming and configuring the personal code and is Do uses these valves like piano keys 1 For example, press the valve 4 in the first hole twice, Then the feature is configured to move the valve in the fourth hole three times and finally the valve in the fifth hole once. Introduced by another sequence. Therefore, the encoding is done in a certain order, in effect It is characterized by the definition of a valve that operates the same valve 4 multiple times in succession. each The valve 4 is coupled to means such as electrical contacts 5 electrically connected to an internal electrical circuit C. The internal electric circuit C recognizes the code thus constructed and uses it as the first code. and open/close or lock/lock according to the comparison result. You can give a command to authorize unlocking, or you can refuse to grant this command and, as the case may be, shall issue an alarm and/or disable the opening/closing or locking/unlocking system. Can be done.

In case of normal use of the device, a preliminary operation consisting of creating a code by means of valve 4 Immediately after, the user performs the pre-approved opening/closing or locking/unlocking operation. Insert your @6 into the correct hole 2 to wake up. Figures 3 to 5 are , is used to visually confirm the correct insertion position of In2 and In6. The means are illustrated.

To this end, each hole 2 or 3 in the grid 1 has a cylindrical or other shape behind the inlet provided with a valve 4. It has a preferably tubular guide part 7 which defines a receiving part in the form of a. Information section 7 is outside The periphery has a pair of holes 8.9 arranged opposite to each other on both ends of the diameter, one of the holes 8.9 being , which accommodates a light emitter such as a discharge light emitting diode 10 2, and the corresponding other hole 9 accommodates a light emitting diode 10. An electric light receiver 11 can be attached. In the variant, the optoelectronic elements are placed apart and can be connected to the guide part 7 by an optical fiber.

A preferably rechargeable power source, such as a battery or accumulator 12, is connected to a suitable circuit 13. By this, power is transmitted to all the light emitters 10 and the light receivers 11. Electric sensing means 14 is placed in the guide part 7 placed behind the entrance of hole 2, and 1116 is inserted into hole 2. From the moment it is turned on, it powers the circuit 13 and therefore the emitter 10 and the receiver 11. (in a manner not shown) to the circuit 13 as shown in FIG. electric sensing hand The step 14 is located at the bottom of the guide 7 and is located when the key 6 is fully inserted into the hole. It is a working contact.

In particular, as FIG. 4 shows, the key 6 itself has a diametrically transverse hole 15. The axial and angular arrangement of the holes 15 is 'The arrangement of the pair of emitter 10 - receiver 1 supported by the guide part 7 of the correct hole 2' It corresponds to the location. Therefore, insertion of the key 6 into the hole 2 at the appropriate angular position This allows transmission of light between a light emitter 10 and a light receiver 11 which are connected across. Contact 1 4 to cause power supply to the emitter 10 and the receiver 11, connect the boss #16 to It can be provided at the end.

In6 is thus certified and the device then performs the desired operation of opening/closing or locking/unlocking. can be caused. FIG. 3 shows, by way of example only, how the device can be used to lock/unlock the door 16. Possible applications are illustrated. The recognition of key 6 (which leads to the formation of the code by valve 4) is , causes the transmission of power to one or more electric motors 17, which for example 8 or other device from top to bottom or from bottom to top or in any direction desired. moving, these bars 18 can be used to directly latch and unhook the door 16, and/or Alternatively, the lock 19 and/or the lock 20 can be locked or unlocked.

The device may further have an alarm 21 powered by the power source 12, the alarm activates in case of wrong operation or attempt to destroy the device, and at the same time the system is disabled. be converted into In particular, the alarm 21 should be activated in case of incorrect operation or an attempt to destroy the device. can move. Therefore, alarm 21 and/or deactivation should be activated in the following cases. I can move.

- In case of no configuration of the cord or incorrect configuration of the cord by valve 4, the ``correct'' 'When the key is used, especially if there is a valve in front of it that is not the first valve to work, and it is touched. As soon as the mule arrives, If something is inserted into hole 3 other than the "correct" hole, even if it is the "correct" key, 1. When an incorrect key is inserted into the ``correct'' hole 2.

Detection of insertion of an object into a hole 3 other than the 'correct' hole is achieved by means of a light emitting device supported by the tubular guide 7. The device 10 is assembled with a valve 4 placed at the entrance of these holes 3 in the same manner as by the receiver 11. This is ensured by integrated electrical means 5. Therefore, the alarm 21 is especially It activates when a malicious person does the following:

τ″Using something to destroy the device instead of the correct key, Either ignore constructing the code by one valve 4 or - Even if you have the “right” key or code, it may not work in some cases. used, but do not have knowledge of the "correct" hole or correct angular position for key insertion.

This device constitutes a code with a valve 4, and in some cases an alarm 21 is activated. , the time required to insert the key 6 into the "correct" hole 2 before the system deactivates it. It has a timer that gives the user the following: The timer has only one hole in the other If it can be distinguished from a hole, it may be a type of code.

Normal use of the device requires the use of the same "correct" hole 2 or two separate "correct" holes 2. In two positions, an opening or unlocking action or an opposite action of closing or locking may occur, as the case may be. The same key 6 can also be inserted in order to

From the above, a very simple and economical cylindrical key can be used safely and without any hindrance according to the present invention. This means that it is sufficient for use in In the end, this key is of only one type. The individuality of each device depends on the definition of the 'correct' hole 2 as well as the valve 4. This is due to the programming of the power code.

However, as Figures 6 and 7 show, even more complex keys can be considered. Ru.

In the case of FIG. 6, the lock is double, on the one hand a hollow outer element 22. On the other hand, inside It is composed of side elements 23. This key is placed in an outer element 22 which forms a kind of sheath. The holes in the side elements 22 are connected to the corresponding holes 25 in the inner element 1F 423 so that the light rays can pass through. It can only be used after engaging the inner element 23 to the correct depth in an angular position corresponding to stomach.

In the case of FIG. 7, the key has a preferably cylindrical shaft 26 with an aperture and an optional It consists of a rotary head 27 which is removable and provided with angular alignment marks.

This latter diagram also shows holes across the key, such as notches, grooves, constrictions, etc.28, and holes in the lattice. It can be replaced by something that plays the same role in cooperation with the rays emitted within. It shows that it can be done.

Operation of the entire device is easily controlled by a timer and simple electrical components or, for example, ROM (read-only memory) or RAM (write-only memory). controlled by at least one microprocessor or similar device; The latter solution involves programming and modifying the code constituted by valve 4. has been confirmed to be advantageous.
