Description

The present invention relates to the field of access control in a protected space and relates to a security lock with unipersonal entry door.

Security locks with a single-door entrance door are already known which form an intermediate space putting in communication an outer space and a protected space and which are provided to ensure a uniqueness of passage, that is to say to not authorize the passage from one space to another only by one person at a time.

Such a unipersonal door security door is generally constituted by an individualization cabin, generally located in the protected space, accessible by a single person and a single-entry entrance door to the protected space. which comprises a passage flap cooperating with said cabin. The passage flap is pivotally mounted, between a closed position of the unipersonal entry door and an intermediate open position, to ensure uniqueness of passage by allowing entry into the individualization cabin, respectively the exit of the latter, to one person at a time.

The intermediate opening position of the passage flap corresponds to a pivoting position of the passage flap where the latter is in contact with a part of the individualization cabin or in the immediate vicinity thereof so as to allow a passage opening. sufficient of the unipersonal entrance door, while ensuring the closing of the entry into the protected space from said cabin, as long as the passage flap is maintained in said intermediate open position. The entry into the protected space from the individualization cabin is then released by a pivotal return of the passage flap in its closed position of the single-door entry door. Conversely, the closure of the unipersonal entry door by the passage flap frees entry into the personalization cabin from the protected space and, when a person is present in said cabin, the pivoting of the passage flap to in the middle open position has the effect of opening the front door unipersonal and to allow said person to go out into the outdoor space.

The document U.S. Patent No. 4,947,765 discloses such a security lock comprising two walls extending at a distance from a main door passage flap and forming with this passage flap, in an intermediate opening position, a space of individualization, which can not be taken out only after closing the door to enter a protected room.

However, this type of airlock does not allow to release a passage of a width sufficient to meet including a need for security during an emergency evacuation or for passing large objects.

The document EP 1 189 178 relates to a passage device for a protected space comprising a passage flap which is pivotally held to a movable frame pivotally mounted to the side of the building so that it can be pivoted out about a vertical axis to put in clearance configuration the door. It also comprises an individualization cabin associated with the free vertical edge of the passage flap, including a first partition, which, in operation, leads from the plane of the frame, as well as a second partition spaced from this plane, in which the cabin of individualization is arranged in the protected space.

However, the security chamber described in this document comprises a mobile frame which must be adapted specifically with additional pivoting and unlocking means to be movable pivotally, together with the gate flap, outwards in order to put the airlock in a situation of disengagement, which complicates the structure of the airlock and increases all its cost price. In addition, the mobility of the sleeping frame does not allow an adaptation of the airlock on fixed dormant frames.

The document FR 2,855,549 relates to a device for secure access to a room comprising a first door pivoting about a first axis capable of closing at least partially the opening of the door, and a second door pivoting about a second axis, separate from said first axis and a release flap.

However, the airlock described in this document requires, in addition to the presence of a release flap, the presence of two consecutive passage flaps to cross the airlock from outside to the secure local and reciprocally, namely a first passing flap to access the airlock from the outside and a second passing flap to access the secure room from the airlock.

Such an airlock has a complex constitution resulting in a high manufacturing cost and does not allow a configuration of quick and easy release, depending on the requirements, including security or the passage of bulky goods.

The object of the present invention is to overcome these drawbacks by proposing a unipersonal door security lock with the possibility of modulating the dimensions of the main entrance opening as a function of the passage requirements, in particular for passing large objects. dimensions or to allow an emergency evacuation of the people present in the protected premises, while being moreover of simpler design than known security locks such as those described above, with a lower cost.

For this purpose, the unipersonal door security lock intended to allow access control in a protected space according to the present invention comprises a double-leafed single-door entry door having a single passage flap to ensure both the door and the door. entry into the airlock from outside and entry into the protected space from the airlock and vice versa. cooperating with an individualization cabin, said passage flap being pivotally mounted between a closing position of the unipersonal entrance door and an intermediate opening position in said individualization cabin to ensure uniqueness of passage and allow the entry into the individualization booth or the exit of the latter.

Such a security lock, according to the present invention, is essentially characterized in that the double-leaf door comprises a fixed fixed frame in which are pivotally mounted a passage flap and a release flap, said release flap being locked in said fixed fixed frame in access control configuration of the single-door entry door, in that a set of unlocking means is able to release, on the one hand, the pivoting of the passage flap beyond its position intermediate opening into a disengaged opening position and, on the other hand, pivoting of the disengagement leaf into a disengagement opening position, for disengagement configuration of the unipersonal entrance door. , and in that said respectively passage and clearance flaps are assembled to the vertical uprights of the fixed fixed frame by means of a specific shaped round pivot connection ifiquement to allow a pivoting of said leaves on at least 180 ° so as to allow an opening of said leaves within the protected space, to allow in particular the passage of large objects, or outside said space protected, in particular in case of lack of space inside or to facilitate an emergency evacuation of the persons present in said protected space.

• the figure 1d represents a cross-sectional view of a safety lock according to the present invention in a preferred method of assembling the two leaves of the single-door entrance door to the fixed fixed frame, in an opening-out configuration of the leaf passage and the release flap.

The figures show a unipersonal door security lock, according to the present invention, intended to allow access control in a protected space 1 of the type comprising a single-door entrance door 2 comprising a passing door 4 cooperating with a cabin of 3, said passage flap 4 being pivotally mounted between a closed position of the unipersonal entrance door 2 and an intermediate open position ( figure 1b ) in said individualization cabin 3 to ensure uniqueness of passage and allow entry into the individualization booth or the exit of the latter.

According to the present invention the unipersonal entrance door 2 is a double-leaf door 4, 5 comprising a fixed fixed frame 6 in which are pivotally mounted a passage flap 4 and a release flap 5, said release flap 5 being locked in said fixed fixed frame 6 in access control configuration of the unipersonal entrance door 2.

Still in accordance with the present invention, a set of unlocking means will be able to release, on the one hand, the pivoting of the passage flap 4 beyond its intermediate open position ( figure 1b ) to a release opening position ( Figure 1c, Figure 1d ) and, on the other hand, the pivoting of the release flap 5 for an opening in a disengagement opening position, this for a setting in release configuration of the unipersonal entrance door 2 allowing, in particular, the passage of large equipment or emergency evacuation.

By double-leaf door 4, 5 is meant two wings 4, 5 pivotally mounted relative to one another in a fixed fixed frame 6, each around a vertical axis, so that their pivoting fits into each other. more particularly in two adjacent or substantially adjacent circles.

In a preferred embodiment of the present invention, the personalization booth 3 may comprise a movable partition 7 situated at a distance from the unipersonal entry door 2, preferably on the side of the release flap 5, which can be folded down in unipersonal entrance door release configuration 2.

The movable partition 7 will comprise an unlocking means making it possible, on the one hand, to maintain it in a position forming a partition of the individualisation booth 3, preferably by extending parallel or substantially parallel to the fixed frame 6 ( Figures 1a and 1b ) and, on the other hand, after unlocking, to release it in pivoting, in particular in view of its folding in the configuration of the unipersonal entrance door 2 ( figures 1b , 1c and 1d ).

Note that the folding of the movable partition 7 corresponds to a free pivoting of said partition 7 about a vertical axis 7 "allowing it to be folded perpendicularly or substantially perpendicular to the fixed frame 6 that is outward of the protected space 1 as shown in the figures, or in a variant towards the inside of the latter.

For this purpose the movable partition 7 is advantageously pivotally mounted on a wall or a fixed partition wall 8 which preferably extends perpendicularly or substantially perpendicularly to the fixed fixed frame 6. The folding of the movable partition 7 will therefore be carried out in the direction of said wall wall or fixed partition 8 in a direction of pivot towards the outside of the protected space 1 (as shown in the figures) or in a variant towards the inside of the latter.

The movable partition 7 may be able to prevent the opening of the passage flap 4 beyond the intermediate opening position and the unlocking of said movable partition 7 will then have the effect of also releasing the pivoting of the passage flap 4 to beyond the intermediate open position to bring it into a release opening position.

For this purpose, it can be seen in the figures that the movable partition 7 is provided at its free end edge with a protruding piece 7 'forming a stop of the passage flap 4 so as to limit the pivoting thereof until at the intermediate open position.

It will therefore be understood that advantageously, after the unlocking of the movable partition 7, particularly in view of its folding, or said movable partition 7 will be folded in a first step which will also have the effect of releasing the pivoting of the passage flap 4 to beyond the intermediate opening position, the flap of passage 4 will be pivoted beyond the intermediate open position by exerting a thrust on said movable partition 7 become free to pivot after unlocking.

This intermediate opening position of the passage flap 4, which is defined when the latter comes into abutment of the projecting piece 7 ' of the movable partition 7, corresponds, on the one hand, to a sufficient opening of the unipersonal entrance door 2 so that a person can enter from the outside into the individualization cabin 3 and, on the other hand, closing the entry in the protected space 1 from the individualization cabin, as long as the flap passage 4 is maintained in said intermediate open position.

Subsequently, once the person who wishes to enter the protected space 1 is in the individualization booth 3, a pivoting return of the passage flap 4 in the closed position of the unipersonal entrance door 2 will then the effect of opening the entrance to the protected space 1 from the personalization booth 3 allowing the only person present in the customization cabin 3 and authorized to enter the protected space 1 to access this latest.

Conversely, the intermediate open position corresponds to a closing of the exit of the protected space 1 and to a sufficient opening of the unipersonal entrance door to allow the only person present in the individualization cabin and who wishes to leave from the protected area 1 to access the outdoor area.

The passage flap 4 thus plays in a known manner the role of a passage filter allowing one person to pass at a time from an outside space to a protected space 1 and vice versa.

In a variant of the abutment 7 'of the movable partition 7 limiting the pivoting of the passage flap 4 to the intermediate open position, said flap 4 can be held in the intermediate open position by means of a device locking device, not shown, fixed on the fixed fixed frame 6, consisting for example of a pawl system preventing a pivoting of the passage flap 4 beyond the intermediate open position, that is to say beyond beyond a pivoting position of said leaf 4 whose free end edge 4 'is located in the immediate vicinity of the movable partition 7 of the individualization booth 3 ( figure 1b ).

Unlocking the locking device may advantageously make it possible to release the pivoting of the passage flap 4 beyond the intermediate open position to bring it into a release opening position.

Thus, the unlocking means of the locking device or the unlocking means of the movable partition 7 will constitute advantageously the unlocking means of the passage flap 4 to release it pivotally beyond the intermediate open position.

Note that the unlocking means of the movable partition 7, the locking device, the passage flap 4 and the release flap 5 may be for example retractable locks, possibly remote controlled.

In addition, to prevent an unauthorized person taking advantage of the passage of a person from the individualization cabin 3 in the outdoor space to enter the cabin 3 and access the protected space 1, the security lock according to the present invention may advantageously comprise a presence detector connected to a control electronics of a non-return device with unlocking means, not shown, adapted to block the flap 4 in the intermediate open position and closing the entrance in the protected space 1 from the individualization cabin 3, as long as the unauthorized person is present in said cabin.

As can be seen on the figure 1c , the movable partition 7 will advantageously be able to be folded, after unlocking, to allow pivoting of the passage flap 4 in a release opening position, perpendicular or substantially perpendicular to the fixed fixed frame 6, beyond the intermediate open position. For this purpose, it may be pivotally mounted, for example by means of a hinge, on a wall wall or on a fixed partition 8 which extends perpendicularly to the fixed fixed frame 6.

Still in a preferred embodiment of the present invention, the movable partition 7 and the release flap 5 will advantageously be able to be folded respectively 7 on the other 5, perpendicular or substantially perpendicular to the fixed fixed frame 6, in unipersonal 2 door entry release configuration ( figure 1c ). Of course, without departing from the scope of the present invention, it could also be envisaged to fold the movable partition 7 first and then the release flap 5 on said movable partition 7.

In the configuration of release of the entrance door, that is to say in a large opening configuration of the single-door entrance door 2 to allow in particular the passage of objects of large dimensions, the passing door 4 and the release flap 5 will preferably be open inside ie in the protected space 1 as shown in FIG. figure 1c .

However in a variant it can be provided, as can be seen on the figure 1d , to open the passage flap 4 and the release flap 5 towards the outside (arrow E), this in particular in the event of lack of space inside or to favor an emergency evacuation of the persons present in the protected space 1. In this variant, the movable partition 7 and the release flap 5 are no longer folded one on the other but in the extension of one another in the same plane or substantially in the same plane perpendicular or substantially perpendicular to the fixed fixed frame 6.

For this purpose, if we refer to Figures 1a, 1b , 1c and 1d it can be seen that the passage flap 4 and the release flap 5 are assembled to the vertical uprights of the fixed fixed frame 6 by means of a round pivot connection 9 shaped specifically to allow a pivoting of said flaps over at least 180 ° so as to allow an opening of said leaves 4, 5 inside the protected space 1 ( figure 1c ) or outside of it ( figure 1d ).

More particularly, it can be seen that the passage flap 4 and the release flap 5 are assembled to two vertical uprights of the fixed fixed frame 6, each of which has a vertical internal face of complementary recessed contact of the outer face of rounded contact of the edge. interior of the wing 4, 5 corresponding.

Thus, thanks to the security lock according to the present invention, the release configuration of the entrance door can be achieved by an opening of the leaves respectively passage 4 and clearance 5 either inwardly or towards the outside, depending on the situation, while maintaining a fixed fixed frame unlike the existing airlock which comprise for this purpose a mobile frame pivotally mounted and associated with additional locking means. The airlock according to the present invention also has the advantage of having a single passage flap to ensure both the entry into the airlock from the outside and the entry into the protected space from the airlock and vice versa, while playing a role uniqueness by allowing the passage from one space to another by only one person, unlike the existing airlock requiring the presence of two leaves passing to cross the airlock.

The airlock according to the present invention may advantageously comprise a central unlocking system simultaneously controlling the unlocking of the movable partition 7 with a view to its folding, the unlocking of the passage flap 4 to release its pivoting beyond the intermediate open position. to a release opening position and unlocking the release flap 5 to release its opening to a release opening position.

According to an additional feature, the airlock according to the present invention may comprise a mechanical or electronic control non-return device to allow a single cycle or deflection per passage.

Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
