Electromechanical device for unlocking the lock of a bank deposit box

Description

[0001] In one aspect, the present invention relates to an electromechanical device for unlocking the lock of a bank compartment. The lock comprises a first locking mechanism associated with a key, and a second locking mechanism associated with another key. The first locking mechanism is actuated, using its associated key, to allow the lock to be opened by activating the second locking mechanism with the other key. In a second aspect, the invention relates to a bank compartment equipped with a lock as described above, as well as an electromechanical device conforming to the first aspect of the invention.Finally, by a third aspect, the invention relates to an installation comprising a plurality of bank compartments conforming to the second aspect of the invention, the electromechanical unlocking devices of the different bank compartments of the installation being controllable from a control station located away. EARLIER ART

[0002] A bank vault, or safe deposit box, is a type of lockable compartment that banks rent to individuals who wish to store valuables. The lock on a typical bank vault has two locking mechanisms, each associated with a key known as the "customer key" and the "bank key." When a customer rents a vault, they are given the customer key, which they must keep safe. Subsequently, when the customer wants to access the vault, they must go to the bank with their key and be escorted to the vault room by an employee who has the bank key. The bank employee and the customer must use both keys together to open the vault. Generally, the customer keys for the different vaults are all different, and the bank does not keep copies when renting a vault.The bank key, on the other hand, is generally the same for all safe deposit boxes.

[0003] In most cases, the customer must first use their key to activate one of the two locking mechanisms, and the bank employee must then use the bank key to complete the opening by activating the other locking mechanism. Once this is done, the customer can access their banking compartment.

[0004] The customer's key remains trapped inside one of the lock's locking mechanisms until the bank compartment is closed and locked. To close the lock, the customer must again ask the employee to relock the other locking mechanism with the bank key. Once this is done, the customer can turn their own key back in the lock and remove it.

[0005] It is clear from the above that each customer wishing to access their bank compartment must go to the vault accompanied by a bank employee. This employee must also remain available to the customer to then close the compartment. A primary drawback of such a procedure is its high staffing cost. Another drawback relates to security. Indeed, it cannot be entirely ruled out that a dishonest employee might, for example, discreetly borrow the bank key to make a copy. Furthermore, the loss of this key, or damage rendering it unusable, could compromise the proper operation of the entire vault.

[0006] To address the problems just described, it has been proposed to create bank vaults that can be unlocked without using a bank key. According to this established solution, the lock on each vault is equipped with a remote-controlled locking system that replaces the traditional locking mechanism associated with the bank key. This change allows a bank employee to activate the locking systems of the various vaults from a control console located outside the vault. This solution is satisfactory when implemented in new facilities designed from the outset to operate in this way. However, it presents problems when modernizing an existing facility with vaults equipped with mechanical locks.Indeed, to change the locks, the bank needs access to the inside of the compartments. This isn't possible without the customers being present. This creates organizational and customer contact problems, and these problems are practically insurmountable.

[0007] US patent document 5,219,386 describes an electromechanical device for actuating the lock of a bank vault compartment, suitable for installation on a bank vault compartment in a pre-existing vault room. However, access to the inside of the bank vault compartment is required to install the electromechanical device. Once installed, the device can exchange data with a remote control station via a wired network, which also provides power to the device and enables remote control. Communication with the electromechanical device is interrupted when the bank vault compartment door is opened.

[0008] Patent document CH 700 937 B1 describes an electromechanical device for actuating the lock of a bank compartment that can be installed on the door of a pre-existing bank compartment without requiring access to the interior of the compartment. The electromechanical device is equipped with radio communication means enabling remote control of the bank compartment lock. The electromechanical device operates using power supplied by a battery that must be replaced periodically. BRIEF SUMMARY OF THE INVENTION

[0009] One object of the present invention is to overcome the drawbacks of the prior art just described. The present invention achieves this object, as well as others, by providing, according to its first aspect, an electromechanical device for unlocking the lock of a bank compartment according to claim 1. It further achieves the same objects by providing, according to its second aspect, a bank compartment according to claim 8. Finally, it also achieves the same objects by providing, according to its third aspect, a bank compartment installation according to claim 9.

[0010] According to the invention, the electromechanical device is fixed to the bank compartment; in other words, on the outside of it. Such an electromechanical device is therefore suitable for installation on a bank compartment of a pre-existing installation, without it being necessary to open the compartment.

[0011] Furthermore, the key for one of the two locking mechanisms is mounted as a pivot within the electromechanical device and is held engaged in its associated locking mechanism. In other words, the key remains permanently coupled to its corresponding locking mechanism. This feature prevents the key from being removed from the lock without first dismantling the electromechanical device or at least separating it from the bank compartment. Therefore, it is impossible to remove the key without attracting attention.

[0012] The electromechanical devices of the various compartments of an installation according to the invention are further powered by electricity via an electrical cable. An advantage of this feature is that the electromechanical devices do not require a battery to operate. Therefore, there is no need to periodically replace batteries. It is understandable that, in the case of an installation with several hundred, or even thousands, of bank compartments, replacing batteries would be an extremely long and tedious operation. Moreover, to ensure the operation of an electromechanical device for a sufficiently long period, for example, for a year or even two years, the batteries used would have to be relatively large. The presence of such batteries would thus make the electromechanical devices more cumbersome.

[0013] According to the invention, the cables supplying electricity to the electromechanical devices also function as a wired network through which the electromechanical devices can exchange data with a remote control station. In particular, it is possible to control the electromechanical device of each of the different banking compartments from the control station via the wired network. This feature allows each electromechanical device to be remotely switched between a locked configuration, in which the key mounted to rotate within the electromechanical device is blocked, and an unlocked configuration, in which the locking mechanism associated with the key can be operated by turning it.

[0014] Other features and advantages of the present invention will become apparent from the following description, given solely by way of non-limiting example, and made with reference to the accompanying drawings in which: THE figures 1A et 1B are perspective views, respectively from the front and rear sides, of an electromechanical unlocking device that conforms to a particular embodiment of the invention; figure 2A is a plan view of the rear side of the electromechanical unlocking device figures 1A et 1B : there figure 2B is a longitudinal cross-sectional view of the electromechanical unlocking device figures 1A, 1B And 2A ; there figure 3 is a front plan view of a traditional bank compartment; the figure 4 is a partial cutaway plan view from the front of a bank compartment installation equipped with electromechanical devices identical to those of the figures 1A, 1B , 2A et 2B . DETAILED DESCRIPTION OF A METHOD OF IMPLEMENTATION

[0015] There figure 3 This illustrates a traditional bank compartment. This type of compartment is characterized by having a lock that includes two separate locking mechanisms, each operated with a key. ad hoc. Nowadays, only a few examples of such compartments are produced. However, many banks still have vaults equipped with several hundred, or even sometimes thousands, of banking compartments like the one in the figure 3 .

[0016] The banking compartment illustrated in the figure 3 It takes the form of a locker closed by a rectangular door (reference 1) which is pivotally mounted on one of the locker's walls by means of two hinges (reference 2). When several bank compartments are installed in the same room, known as the vault room, they each bear an identification number (reference 5). The bank compartment illustrated in the figure 3 It is thus numbered "55". It should also be noted that door 1 of the banking compartment has the distinctive feature of being equipped with two separate keyholes. The first keyhole (referenced 3) allows one of the two locking mechanisms to be operated with a key, and the second keyhole (referenced 4) allows the second locking mechanism to be operated with another key. In the following example, the key associated with the first keyhole 3 is the banking key, while the key associated with the second keyhole 4 is the customer key. However, it will be understood that, according to other embodiments of the invention, this is the reverse.

[0017] THE figures 1A et 1B are respectively front and rear views of an electromechanical unlocking device that conforms to an exemplary embodiment of the invention. The illustrated electromechanical device is intended to be affixed to the door of a bank compartment that requires two keys to open (the compartment is not shown in the figures 1A et 1B (but it will be understood that it is the rear side of the electromechanical device that is fixed against the compartment door). In what follows, we will assume, as an example, that the bank compartment to which the electromechanical device is fixed is the bank compartment shown in the figure 3 The electromechanical device in this example comprises several active parts, which will be described later. These active parts are housed inside a casing (referenced 11) generally shaped like a hollow rectangular plate that is open at the rear (as shown in the diagram). figure 1B ). It will be understood that the width and height of the plate are preferably equal to the width and height of the rectangular door of the bank compartment on which the device is intended to be fixed. Referring now to the figure 1A As can be seen, the front face of the housing 11 has a shoulder (reference 13) that separates a thicker part (the housing itself) from a thin, blade-shaped extension (reference 15). The two main functions of this extension are to facilitate the positioning of the housing 11 on the door 1 of the bank compartment and to reinforce the housing's attachment to it. It will be understood, however, that in other embodiments, the housing lacks such an extension. figure 1B It also shows that the bottom (in other words the front) of the case is lined by a printed circuit board (reference 16). This is intended to ensure the connection of the various electrical and electromechanical components of the device.

[0018] The electromechanical device in this example is intended to be positioned on the door 1 of a bank compartment in such a way that the extension 15 of the housing 11 is on the side of the hinges 2 (cf. fig. 3 ). Always referring to the figure 1A We can see a rotary knob (referenced 17) which is positioned in line with the axis of the first keyhole 3, and a through opening (referenced 19) which is arranged in line with the axis of the second keyhole 4. We can also see a light (referenced 21) and two through openings (referenced 23a and 23b) which all three communicate with the interior of the housing 11, as well as two through holes (referenced 25a and 25b) which are provided for screws to fix the electromechanical device to the compartment door.

[0019] We will now describe the active parts of the electromechanical device, referring more specifically to the figures 2A et 2B . There figure 2A This is a schematic plan view of the rear side of the electromechanical device in this example. The active parts of the electromechanical device are arranged inside a housing (reference 27) that occupies the space between the hollow casing 11 and the outer face of the door 1 of the banking compartment. The active parts of the electromechanical device include, firstly, a micro-actuator (reference 29). In the illustrated example, the micro-actuator 29 is a double-acting linear actuator that has a drive shaft designed to switch by sliding longitudinally in one direction or the other between two predefined positions, in response to control signals received by the micro-actuator. It should be understood, however, that the latter could alternatively be an actuator or a servomotor of another type.The electromechanical device also includes a latch (reference 31) which is equipped with a first and a second actuating arm (referenced 33a and 33b respectively). As can be seen in the... figure 2A The end of the first arm 33a is secured to the actuator's drive shaft 29 by means of a pin (not shown). The electromechanical device also includes a distance sensor (reference 35), and first, second, and third mechanical position sensors (referenced 37, 38, and 39, respectively). Now, referring to the figure 2B , we can still see a key (reference 41) whose head has been replaced by the rotary knob 17 already mentioned in connection with the figure 1A It can also be seen that, in the illustrated example, the key can be of the double-bitted type, as is often the case with traditional bank compartment keys. According to the invention, the key 41 is pivotally mounted in the electromechanical device. In the illustrated example, the shaft of the key 41 passes through a hole in the housing 11 so as to protrude on either side of it. The end of the shaft of the key 41, which carries the rotary knob 17, thus protrudes from the front face of the housing 11, while the keyhole 41 emerges from the rear face. It will be understood that, when the electromechanical device is fixed in position on the door 1 of the bank compartment, the hole through which the shaft of the key 41 passes is located exactly in line with the axis of the first keyhole 3 originally provided for the bank key. The reception of the key 41 can thus extend inside the keyhole 3.It will also be understood that, as long as the electromechanical device remains fixed to the door of the bank compartment, the key 41 is held captive inside the keyhole.

[0020] The other end of the key shaft 41 carries the button 17, and it can be seen that the portion of the shaft to which the button is attached is shaped like a cylinder (referenced 43) of relatively large diameter. It can be understood that this cylindrical portion of the key shaft 41 bears, at its end opposite the button 17, against the front face of the housing 11, which allows the cylindrical portion 43 to pivot against the front face of the housing 11 when the key 41 turns in the keyhole. Referring again to the figure 2A A tang (reference 45) can be seen, fixed to the end of the cylindrical portion 43 and inserted into a semicircular slot (reference 47) formed in the wall of the housing 11. The tang is long enough to protrude from the slot inside the housing. Since the semicircular slot is concentric with the axis of the key 41, the tang travels along the slot 47 in one direction or the other when the key 41 is turned in the keyhole 3. As already mentioned, the housing 11 of the electromechanical device also includes a through opening 19 arranged in line with the axis of the second keyhole 4. The opening 19 provides a passage for inserting the customer's key into the second keyhole.

[0021] We will now describe the operation of the electromechanical device in this example. The latch 31 is guided in a slide of the housing 11 so that it can move in either direction parallel to the direction of movement of the control shaft of the micro-actuator 29. It is thus possible to switch the latch 31 between an inactive and an active position by controlling the micro-actuator. Referring again to the figure 2A As can be seen, the shape of the lock 31 is fully represented in its inactive position, and its outline is further represented by a dashed line in its active position. Specifically, in the active position of the lock, the actuating arm 33a is superimposed on the arcuate slot 47. It is clear that in this position, it is not possible to turn the key 41 because the tang 45 abuts against the end of the actuating arm 33a. Conversely, when the lock is in its inactive position, the tang 45 is free to move along the arcuate slot 47. The key 41 is then free to turn.

[0022] When the bank vault compartments are equipped with electromechanical unlocking devices like the one just described, a customer wishing to access their compartment must first present themselves at the counter with their key and identification. Once the clerk has verified the customer's identity, they are allowed access to the vault. The clerk then remotely activates the lock on the electromechanical device attached to the customer's compartment door, without leaving their station, using a control panel. Upon reaching their safe deposit box, the customer first uses their own key to activate one of the two locking mechanisms on the compartment door (1). They then turn the other key (41) using the rotary knob (17) to activate the second locking mechanism and fully unlock the compartment.Once this operation is completed, the customer can access the contents of their safe deposit box. The customer's key remains trapped inside the lock until the bank compartment has been closed and locked. To close the lock, the customer must first turn the rotary knob 17 backward, so as to re-lock the mechanism associated with the key 41. Once this is done, they can turn their own key backward in the lock and remove it. It is important to note, however, that the double locks of known bank compartments do not all operate in exactly the same way. Thus, according to other embodiments of the invention, the customer might first have to turn the key that is permanently mounted in the electromechanical device before being able to use their own key to operate the other mechanism.On the other hand, according to some of these latter embodiments or according to other embodiments, the sequence in which the customer must operate to close the bank compartment could be reversed.

[0023] As illustrated by the procedure just described, one advantage of installing electromechanical devices according to the invention on the bank vault compartments is that it is no longer necessary for a bank employee to accompany the customer to their safe deposit box. However, this change can pose new security problems. Indeed, a customer entering the vault unaccompanied could potentially take advantage of the situation to try to access a bank compartment that is not theirs. In order to prevent this risk and, more generally, to improve security, the electromechanical device in this example is equipped with a number of sensors connected to a remote control station via a wired local area network, which also transmits the control signals to the linear actuator 29.

[0024] The 35 distance sensor already mentioned in relation to the figure 2A This allows for real-time monitoring of the distance between the door leaf and the frame of the door to which the electromechanical device is attached. This device therefore allows for continuous monitoring of whether a bank compartment door is open or closed. In this example, the distance sensor is a laser (or lidar) sensor. Referring again to the figure 2A As can be seen, it is positioned in the housing 11 opposite the edge of the door 1, which is on the opposite side from the hinges 2 (on the pull side of the door). It will be understood that the laser beam from the sensor 35 is oriented so as to strike one of the fixed walls of the bank compartment through the light 21. Those skilled in the art will also understand that the distance sensor 35 is not necessarily a laser sensor, but could operate according to another principle.

[0025] As for the mechanical position detector 37, its function is to monitor that the lock 31 is in the active position, thus triggering an alarm when the lock moves to the inactive position. Mechanical position detectors are well-known. They can operate on the principle of a small switch controlled by an actuating element such as a lever or a push button. In this example, when the lock 31 is in the active position, it exerts pressure on the actuating element of the sensor 37. As soon as the lock 31 leaves the active position, the pressure it was exerting on the actuating element is released, causing the switch to close.

[0026] The electromechanical device in this example also has an "anti-tamper" alarm. This alarm operates using the second and third mechanical position sensors 38, 39 already mentioned in connection with the figure 2A Sensors 38 and 39 are mounted in housing 11 so that the front face of door 1 of the banking compartment exerts pressure on their actuating element as long as the electromechanical device is attached to the door. If someone detaches the electromechanical device from door 1, the pressure exerted on the actuating element is interrupted, thus triggering the alarm.

[0027] The electromechanical device in this example also includes a mechanical emergency opening system designed to compensate for any electronic or electrical failure. As previously noted, the housing 11 of the electromechanical device has a through opening 19 which is aligned with the axis of the keyhole 4 provided for the customer's key. Referring again to the figure 2A , we can see that the end of the second actuating arm 33b of the lock 31 is in the immediate vicinity of the axis common to the opening 19 and the second keyhole 4. It will be understood that it is possible to actuate the lock 31 by inserting an emergency key through the opening 19 so as to push back the second actuating arm 33b in one direction or the other, so as to manually move the lock 31 from the active position to the inactive position, or vice versa.

[0028] There figure 4 This is a partial cutaway plan view from the front showing six bank compartments equipped with electromechanical devices, each conforming to the exemplary embodiment described herein. It will be understood that the six illustrated bank compartments may be part of an installation comprising a much larger number of bank compartments. As has been seen, according to the invention, the electromechanical devices of a bank compartment installation are capable of exchanging data with a remote control station via a wired network (for example, the bank's LAN). This remote control station also provides the power supply to the electromechanical device and allows it to be controlled from the control station to switch the lock 31 between its active and inactive positions.

[0029] By referring to the figure 4 We can see that the different banking compartments are connected in series using small interconnectors (referenced from 51a to 51h) which are in the form of cable segments that can be plugged in at both ends. We can see that the interconnectors shown are each arranged to connect two adjacent electromechanical devices. Furthermore, as already mentioned in relation to the figure 1A The housing 11 of each electromechanical device is provided with two through-holes 23a and 23b arranged in the shoulder 13. Furthermore, the electromechanical devices are equipped with two plugs (not shown) which are mounted inside the housing 11 so that each is accessible through one of the through-holes 23a and 23b. It will be understood that to connect one end of an interconnector 51a, 51b, 51c, 51d, 51e, 51f, 51g, 51h to a plug, it must be inserted through one of the through-holes 23a, 23b. It is therefore possible to connect two electromechanical devices by simply plugging the two ends of an interconnector 51a, 51b, 51c, 51d, 51e, 51f, 51g, 51h into two plugs that do not belong to the same electromechanical device. Note that in the example shown, each interconnector consists of a cable segment with a mini USB male plug at each end.

[0030] Furthermore, it can be seen that in the illustrated example, the interconnector cables do not connect the feedthroughs 23a and 23b by the shortest path. On the contrary, the cables describe wide loops opposite the extensions 15 of the housings. As shown in the figure 4The loops formed by the various cables extend over most of the distance between the opening of the feedthrough 23a or 23b, through which a portion of the cable is connected to an electromechanical device, and the edge of the door (hinge side) to which the device is attached. It will be understood that these loops allow the connectors 51a, 51b, 51c, 51d, 51e, 51f, 51g, and 51h to accommodate the variations in distance between their ends caused by the opening of a compartment door. Furthermore, the fact that the loops described by the cable portions are located opposite the extensions 15, and that the latter are each located near the hinges 2 of the door on which it is fixed, has the effect of limiting the extent of the elongation of the distance between the ends of the interconnectors 51a, 51b, 51c, 51d, 51e, 51f, 51g, 51h, which is generated by the opening of the door of a bank compartment.

[0031] It will be understood from the foregoing that the small interconnectors 51a to 51h are part of the wired network that connects the electromechanical devices installed on the doors of the various bank compartments to the control station, the latter preferably being located outside the vault. According to an advantageous variant of this embodiment, the wired network that connects the electromechanical devices can be a LAN arranged in a series configuration whereby each cable segment exits one electromechanical device and enters the next. Finally, the series configuration can preferably be a loop configuration.

[0032] It will also be understood that various modifications and / or improvements obvious to a person skilled in the art can be made to the embodiment which is the subject of this description without departing from the scope of the present invention as defined by the attached claims.
