Definitions
- the present invention relates to a drive device for locking and unlocking a lock with conditional opening. More particularly, the invention relates to the application of this device to a time lock known as a high degree of security, intended to control, over determined time slots, the access to high security enclosures, such as safes -forts or vaults, for example from bank branches. The invention therefore also relates to the application of this device to high security enclosures, such as safes or vaults.
- the closing of a PO door of a safe or any other high security enclosure is generally, using several bolts PT controlled by a linkage TR, this linkage being able to be moved, by an operator, using a steering wheel VO, from a locking position to an unlocking position and Conversely .
- the linkage TR comprises a bar B which controls the movement of the bolts PT of the door PO and which is coupled to the steering wheel VO, by means of a mechanism of the wheel-rack type.
- This bar B can be moved, in translation, under the action of the flywheel VO, to order the displacement of the bolts PT and to ensure the operations of locking (bolts extended) and unlocking (bolts retracted).
- this assembly comprises a first lock S which is itself provided with a bolt PS intended to come s' engage in bar B.
- the bolt PS is therefore provided to block the translational movement of the bar B.
- This first lock S can be controlled, in the simplest version by a key, or even by more sophisticated means, such as a magnetic card, a smart card or an electronic system operating with a code or other type of access authorization.
- a second lock SH called a time lock.
- This time lock SH also has its own bolt PV, which is more generally known as a bolt or locking block and which is intended to be placed on the path of the bar B, in order to hinder its movement towards the unlocking position. .
- the bar B In the high position of the PV block shown in FIG. 1a, the bar B therefore comes to butter, by its rear end, against the PV block.
- the PV locking block is associated, in this time lock SH, with a drive device DEN, comprising in particular (FIG. 1b) an electromagnetic motor MEL and an MCL mechanism comprising a cam ⁇ A formed to drive a lever LE.
- a drive device DEN comprising in particular (FIG. 1b) an electromagnetic motor MEL and an MCL mechanism comprising a cam ⁇ A formed to drive a lever LE.
- the PV locking block can occupy a so-called active high position, shown in FIG. La, preventing the displacement of the bar B and blocking the door PO of one enclosure.
- the PV block can be brought down to a low position called inactive ( Figure lb), by lowering the lever LE, under the action of the motor MEL.
- inactive Figure lb
- the bar B can be moved back, in order to release the bolts PT from the linkage TR. We thus cleared the path of the bar B to allow the door to open.
- This drive device DEN can be controlled by electronic means EL (FIG. 1a) associated with display devices PA and data input ED used for the programming of time slots.
- the PA and ED peripherals consist of a digital display and a keyboard.
- the electronic means EL also comprise a microprocessor MP and a memory MM of the RAM / ROM type, the microprocessor MP supplying, from the program stored in the memory MM, control signals which pass through an amplifier AMP, to the device DEN training.
- FIG. lb shows in more detail the DEN drive device which is described in the aforementioned document EP 0 256 430. It can be seen that the locking block PV is associated with a compression spring R which is supported by a piloted rod TG by the drive device DE. More particularly, the PV block has a longitudinal recess in which the rod TG can slide which is retained by a screw.
- the rod TG has at its base a shoulder, the spring TG being interposed between this shoulder and the base of the PV block.
- the spring R is compressed under the effect of the MCL mechanism which continues to run under the impulse of the MEL motor.
- the PV block can come to occupy its active high position when the bar B is moved to its locking position, to the right in this example.
- the spring R will then supply the PV block with the energy it has stored so that this PV block ends its course in turn and comes to obstruct the path of the bar B.
- this device is single-acting.
- There are also more complex double-acting devices comprising a second spring housed in the rod which is of telescopic structure. This second spring is intended to allow the drive device to end its stroke when the PV block is blocked in the high position by the bar which abuts laterally against it and wedges it in the corridor of the bar B. This device makes it possible to reach the desired result.
- the time lock described in document EP 0 256 430 includes an INH inhibition device making it possible, in the event of a breakdown and by a special procedure, to inhibit the function of blocking of the time lock.
- the INH inhibition device makes it possible to move, against the thrust action of the spring R, the locking block PV from its high active position (FIG. 1 a) to its low position where it is inactive, in order authorize the translation of the bar B and allow the door PO to open to carry out the necessary repair (s) on the time lock.
- the hourly lock SH In its application to a high security enclosure, such as a safe or a strong room, the hourly lock SH is placed and arranged on the door, to be tamper-proof. It is generally inaccessible from outside the enclosure.
- the INH inhibition device makes it possible to avoid this type of intervention.
- This device authorizes by an exception procedure which is controllable from outside the enclosure, the unlocking of the bar, by retracting the PV locking block.
- the INH inhibition device is designed to be able to push the PV locking block down, even if this block is subjected to the stress of the compression spring R which tends to push it upwards.
- the DEN drive device in this type of high security installation, it is necessary to arrange the DEN drive device so that it authorizes, in the event of a breakdown, the return of the PV locking block to its inactive position. , even if the PV block is held by the DEN drive in its active locking position.
- the DEN drive device must therefore be designed to accept the driving action of the INH inhibition device on the PV locking block, in the event that this INH inhibiting device has to move the PV locking block against it. of the force of the spring R, in order to render this block temporarily inoperative. This arrangement must therefore be reversible.
- US Patent 4,633,687 describes a mechanism for driving a lock that can be controlled by a key.
- This lock applies to the closing of hotel doors, where combined closing systems are used, consisting of an electronic key or a purely mechanical key associated with a card capable of delivering a code which can be read and processed. electronically.
- This mechanism includes a device for controlling an auxiliary bolt, which is designed to be able to engage in a recess made in a disc, this disc being linked in rotation to a shaft whose rotation, normally ordered by the key, authorizes the return of the main bolts of the door, for its opening.
- This control device comprises a motor which can be controlled by an electronic circuit, and which can drive a toothed wheel, mechanically linked to the auxiliary bolt by means of a spring and an eccentric mechanism.
- This eccentric mechanism includes a finger or tenon which can slide inside an oblong groove to ensure the translational movement of the auxiliary bolt in the groove of the disc and out of it.
- the object of the present invention is to respond to these drawbacks by providing a compact drive device, of simple structure, which is capable of ensuring reversible movement of the locking block or bolt for unlocking the safety enclosure, especially in the event of a malfunction.
- the subject of the invention is a drive device allowing, in particular the locking of a lock with conditional opening, this device comprising: - motor means comprising a drive element having a first axis of rotation, a transmission arm having a first and a second end, this arm being pivotally mounted by its second end about a second axis of rotation, distinct from the first axis, this arm being provided with a connecting surface, formed in the vicinity of the first end, a locking block mechanically linked to the driving means by the intermediary of the transmission arm, this arm being able to be actuated by the driving means to make the block occupy an active position in which it opposes the displacement of a bar , and an inactive position in which it authorizes its movement, and elastic means making it possible to arm the locking block when it is actuated by the motor means, in particular towards its active position and when its movement is prevented by the bar, characterized in that the elastic means are provided between the drive element and the transmission arm, these elastic means being in direct drive contact with the connecting surface of
- the invention also relates to a drive device comprising: motor means comprising a drive element, - a transmission member provided with a connection surface, a locking block mechanically linked to the motor means by the intermediary of the transmission member, this member being able to be actuated by the motor means to make the block occupy an active position in which it opposes the displacement of a bar, and an inactive position in which it authorizes its displacement, and elastic means making it possible to arm the locking block when it is actuated by the motor means, in particular towards its active position and when its movement is prevented by the bar, characterized in that the elastic means are formed between the drive element and the transmission member, the transmission member being linked to the locking block by means of a rod or connecting rod which is articulated s on the locking block.
- FIG. 1a is a very schematic representation of a conventional safety assembly into which a drive device according to the invention can be incorporated
- FIG. 1b shows in more detail the conventional drive device of FIG.
- FIG. 2a is a front view of a device according to the invention, incorporated in the frame of a time lock and shown in a first characteristic operating position
- FIG. 2b is a rear view of the device of FIG. 2a, shown in the same position
- Figure 2c is a sectional view of the device according to the invention made along the line CC of Figure 2b
- Figure 2d is a sectional view of the device according to the invention made along the line DD of Figure 2b
- FIGS. 3a and 3b are views similar to FIGS. 2a and 2b, but showing the device according to the invention in a second characteristic operating position
- FIGS. 2a to 2d an embodiment of a drive device according to the invention will be described below, identified here by the general reference 10.
- the device 10 according to the invention is mounted in a frame 12 of a SHI lock which is intended to equip a security assembly, such as that shown in FIG. As such, it will be understood from the following description that the SHI lock by being equipped with the device 10 is modified and very simplified.
- the SHI lock according to the invention is therefore also intended to block the movement of a bar B towards its unlocking position, for example in specific time slots, in which it has been decided to prohibit the opening of the door PO ( Figure la), under the same conditions as those explained above.
- the invention is therefore here described in its application to a time lock, since the conditions for opening and closing the door are fixed as a function of determined and programmed time periods.
- the SHI lock is here generically qualified as a conditional opening lock.
- the application to a time lock constitutes a particular and advantageous application which will constitute the embodiment to which reference will be made in this description.
- the SHI lock comprises a PVI locking block which, in this example, is a block of parallelepiped shape which can slide between two characteristic high and low positions, by translating in a guide 14, formed by two parallel walls 16 and 18.
- the PVI block is mounted in the guide 14 with significant lateral operating clearances allowing it to slide, without friction, between its two positions.
- the PVI block is represented in FIG. 2a in a position referenced P2, called the inactive position, in which it does not interfere with the displacement of the bar B of the linkage TR. In this position, the PVI block rests against a stop 20 which is formed by shoulders 22 formed at the base of the walls 16 and 18.
- the bar B can therefore slide in a corridor CR between its locking and unlocking positions, under the control of the steering wheel VO (FIG. 1a), in order to allow the door PO to be opened or closed. by the set of bolts PT of the TR linkage.
- the PVI locking block is, in this example, connected by a conventional articulation, not shown, to a rod or connecting rod TGI which is itself connected, by an articulation or pivot 24, to a first end 26a of an arm of transmission 26 ( Figure 2b).
- the articulation or pivot 24 is constituted by a pin 25 mounted and adjusted freely in rotation in one or two bores 27 formed in the rod TGI and / or in the end of the transmission arm 26.
- the pin 25 can be attached or secured TGI rod or arm 26.
- the transmission arm 26 is pivotally mounted by a second end 26b and it is coupled, in the vicinity of its first end 26a, to motor means MT.
- the rod TGI and the transmission arm 26 constitute a transmission member 28 which connects the PVI locking block mechanically to the MV motor means and which ensures the transmission of the energy supplied by the MV motor means to this PVI locking block .
- the motor means MT comprise an electric motor 30 (FIGS. 2a and 2d) which is supplied and controlled by an electronic control unit ELI (FIG. 1a).
- the motor 30 is mounted on a plate 32 ( Figure 2d) which is arranged to be able to be fixed, for example by screws, on the frame 12 of the SHI lock.
- the motor 30 is mounted on the plate 32 on the side opposite to the transmission arm 26.
- This motor 30 comprises a motor shaft, not referenced, at the end of which is provided a drive pinion 34 (FIG. 2d) which opens, relative to the plate 32, on the side of the arm 26, side of the plate where all the functional components of the device are located, which are intended to cooperate and to move.
- the pinion 34 meshes with a drive wheel 36 (Figure 2b) on which is formed a toothed sector 35 in engagement with the teeth of the pinion 34.
- This wheel 36 is mounted free in rotation on an axis 38 ( Figure 2c) driven in the plate 32.
- the toothed sector 35 constitutes means for limiting the angular movement of the wheel 36.
- the wheel 36 also has a flat 40 on which a blade 42 of a position sensor 44 rubs capable of supplying the unit ELI control electronics for signals representative of the angular position of the wheel 36.
- these signals are also representative of the high and low positions of the PVI block, positions called respectively active (referenced Pi, FIG. 3a) and inactive (referenced P2, FIG. 2a).
- the position sensor 44 is, as such, a conventional structure sensor and will not be described here in more detail.
- the wheel 36 also has a bearing surface 46 which extends perpendicularly from the body or the plate of the wheel 36, and coaxially with its geometric axis of rotation XI.
- This bearing surface 46 which constitutes a drive shaft has an elongated cylindrical shape and it projects from the body of the wheel 36, in the direction of the frame 12. It will be noted that the axis 38 which supports the rotating wheel 36 crosses the plank of the wheel 36 and extends over the length of the bearing 46. It will also be specified that the wheel 36 and the bearing 46 form only one piece, the bearing 46 and the board of the wheel 36 coming from material and being made for example of synthetic material, such as polyoxymethylene as the commonly known by the abbreviation POM
- a spring 48 called a clamp spring, is mounted around the bearing 46.
- This spring 48 has a body 48c formed of a helical winding having in this example several turns, the body 48c being positioned freely around the bearing 46.
- the spring 48 also has two radial arms 50 and 51 in the form of a fork, which are provided to drive the transmission member 28, as will be understood below.
- the two arms 50 and 51 and the helical body 48c of the spring 48 are formed of the same elastic wire F.
- This wire can absorb bending stresses and allows the two arms 50 and 51 to open, in certainly situations of drive of the PVI block, then return to their original configuration, after elastic deformation.
- the upper arm 50 is linked to a first turn 48a of the body 48c (FIGS. 2c), this turn 48a resting laterally against the board of the wheel 36.
- the last turn 48b ends in the vicinity of the free end of the range 46.
- the wire F which constitutes the spring 48 has a junction arm 53 which connects the latter turn 48b to the lower arm 51, and which brings this wire F back to the lower arm 51 extending along the body 48c.
- the two arms 50 and 51 are brought back in the same plane substantially parallel to the board of the wheel 36, by a return of the wire F.
- the two arms 50 and 51 extend radially from the bearing surface 46, in substantially parallel directions, towards a lug 52 which projects from the body or plate of the wheel 36.
- the lug 52 is positioned at a radial distance of the bearing surface 46 and of the axis of rotation XI of said wheel, in order to provide a drive torque to the transmission member 28.
- the two arms 50 and 51 of the spring 48 extend on either side of this lug 52 and trap it.
- the lug 52 pushing up or down, clockwise or counterclockwise, one or other of the arms 50 and 51, depending on the direction of rotation printed on said wheel 36 by the motor 30.
- the rotation of the wheel 36 urges the arms 50 and 51 and causes their angular displacement which, in normal function, is simultaneous.
- the device according to the invention 10 further comprises a finger 54 (see FIG. 2b) which projects, parallel to the lug 52 and parallel to the axis of rotation XI of the wheel 36.
- the two arms 50 and 51 of the spring 48 extend on either side of the finger 54 and also enclose and trap this finger 54 just like the lug 52. Consequently, any rotational movement of the wheel 36 in one direction or in another pushes the finger 54 up or down, via the lug 52 and via the arms 50 and
- the rotation of the wheel 36 therefore has the function of causing, in normal operating mode, an upward or downward movement of the finger 54, but with interposition, at this level of the device 10, of elastic movement transmission means formed in this example by the clamp spring 48.
- the finger 54 is integral with the transmission arm 26 which is formed from a stamped metal plate of small thickness having in plan a "J" shape.
- the elbow of the arm 26 is arranged to allow it, when it is in the high position, to come in the vicinity of the wheel 36 (see FIGS. 3b and 5b) and to carry its free end above the wheel 36.
- the finger 54 constitutes a connection surface between the spring 48 and the arm 26 of the transmission member 28. This arrangement provides a compact arrangement which offers an amplitude of movement allowing the block B to be brought into its two extreme positions Pi and P2.
- the finger 54 is formed in the vicinity of a first free end 26a of the arm 26 and it can come integrally with this arm or be driven therein.
- the arm 26 is mounted to rotate freely around a bearing surface 58 which is integral with the plate 32 and which is formed by a head tenon 60 driven into this plate.
- the arm 26 can therefore pivot freely around an axis of rotation X2 (FIG. 2c) which is parallel to the axis of rotation XI of the wheel 36.
- the two axes of rotation XI and X2 are positioned in a horizontal plane PH which is perpendicular to the direction of movement of the PVI block. It will be noted that the axis X2 is distinct from the axis XI and that it is offset relative to the axis XI.
- the device 10 comprises at least two characteristic functional units, namely, on the one hand, the motor means MT, and, on the other hand, the member transmission 28.
- the motor means MT are constituted by the motor 30, the pinion 34, the wheel 36, the lug 52, the spring 48 and its two arms 50 and 51; the finger 54 being coupled to these motor means MT via the spring 48.
- the transmission member 28 is made up of the rod TGI, the articulation 24 and the transmission arm 26.
- the PVI locking block is linked to the motor means MT via the transmission member 28, and via the spring 48 which is interposed and formed between these motor means MT and this transmission member 28.
- the device 10 according to the invention is shown in FIGS. 2a to 2d, in a first characteristic configuration, in which the PVI block is kept in the inactive low position P2, allowing the bar B to move in the corridor CR and to unlock the door PO.
- the sensor 44 informs the electronic unit which deduces therefrom that the PVI block is in the active position PI.
- the electronic unit ELI controls the rotation of the motor 36 in the opposite direction which brings the PVI block down by the same means, in the inactive position P2, the block being able to come into abutment against the stop 20.
- the sensor 44 again informs the electronic unit ELI which deduces therefrom that the PVI block is in the inactive position P2 and that the bar B can be moved to corridor CR for opening the door. The operator can therefore from this moment open the PO door ( Figure la) provided of course that he has the necessary authorization (s) to order the opening of the lock S.
- the electronic unit causes, as it should at the start of a time slot, the rise of the PVI block while the bar B is at the same time in the corridor CR to the right of the guide 14 (the door is therefore not not yet locked), the PVI block will abut against the bar B, the motor 30 will continue its rotation to end its control stroke and the spring 48 will open by elastic spacing of the arms 50 and 51, as shown so exaggerated in Figure 4b.
- the information ordering the displacement of the PVI block towards its active position Pi is recorded mechanically by the spring 48.
- the PVI block which has just been armed will end its race towards its active position PI when the bar B has been translated to right, to its locked position.
- the elastic means 48 are associated functionally and structurally to the motor means MT, and are integrated in the same module, these motor means MT and the elastic means 48 being integral with the same plate. It will also be noted that the elastic means 48 are supported by the motor means MT while being mounted on the drive shaft or carried 46.
- the embodiment which has been described is a double-acting device, since it provides an arming function of the TGI rod and of the PVI block when going up and when going down.
- the invention applies to a single-acting device which, in a simplified version, could only comprise one arm, in particular the lower arm 51, the opposite free part of the spring wire 48 being, in this variant not shown, anchored in an orifice or in a groove formed in the body or the bearing of the wheel 36.
- the spring 48 could also include two arms 50 and 51, the upper arm 50 which cooperates with the lug 52 being in this variant shorter than the arm 51 and not coming up to the level of the finger 54 to leave it free.
