[0004] STATE OF THE ART

[0005] In many fields it is useful to be able to transfer components to or from a confined area without breaching containment, especially when handling these components may present a risk and / or when these components exhibit a certain fragility.

[0006] In this regard, aseptic transfer chambers have been developed. The design of such aseptic transfer chambers must address issues of safety, maneuverability, compactness, maintenance, versatility, and adaptability. Furthermore, all or part of the components of these aseptic transfer chambers must be easily and effectively cleaned.

[0052] DETAILED DESCRIPTION

[0053] System and container

[0054] In order to be able to ensure a transfer of components 10 from, or to, a confined enclosure 100, without breach of confinement, a watertight junction between the enclosure 100 and the external environment is put in place.

[0055] The enclosure 100 is typically a cleanroom, an isolator, or even a laboratory glove box. The enclosure 100 is generally sterile, unlike the external environment, which is generally not. A system 1 to ensure this airtight seal includes a wall 2, a door 3, a coupling device 4, a locking device 5, a safety device 6, a stop 7, and a retaining device 9.

[0056] System 1 is configured to cooperate with a container 8 designed to collect components 10 transferred from enclosure 100 to the external environment, in a sealed and sterile manner. More specifically, container 8 is configured to be sealed to system 1 from the external environment.

[0057] The container 8 comprises an envelope 80, a flange 81 and a lid 82.

[0058] The flange 81 is configured to be fixed to wall 2 of system 1.

[0059] The envelope 80 can be in the form of a flexible film, typically made of plastic, or a rigid-walled container made of plastic, metal, organic and / or ceramic material, forming an envelope intended to contain the components 10. The envelope 80 is fixedly mounted on the flange 81 in a sealed manner.

[0060] The cover 82 is configured to be coupled to the door 3 of system 1 and to seal the container 8 airtight. The cover 82 is removable from the flange 81.

[0061] Wall

[0062] Wall 2 is generally in the form of a flat panel, typically rectangular, intended to be brought in and fixed, for example by embedding, at the level of a passage made through a partition, typically a wall or a window, of enclosure 100.

[0063] Wall 2 serves as a support for system 1. In this respect, it can take any appropriate dimensions corresponding to the passage and include any material suitable for ensuring this structural function.

[0064] Wall 2 defines a through opening 20 through which components 10 are configured to be transferred from, or to, enclosure 100.

[0065] The opening 20 has a shape, typically rectangular, and dimensions which are suitable for ensuring the transfer of components 10 in a simple and practical manner.

[0066] The wall 2 then takes the general form of a frame whose internal edge 21 delimits the opening 20 and an external edge 22 is designed to cooperate with the partition of the confined enclosure 100 in order to fix the wall 2 to it.

[0067] Wall 2 has a first surface 23 and a second surface 24.

[0068] The first surface 23 of wall 2 is intended to extend towards the external environment of enclosure 100, once wall 2 is fixed to the partition of enclosure 100.

[0069] The second surface 24 of wall 2 is opposite the first surface 23 of wall 2, in a direction orthogonal to the plane of wall 2, and is intended to extend opposite enclosure 100 once wall 2 is fixed to the partition of enclosure 100.

[0070] The opening 20 extends between the first surface 23 of wall 2 and the second surface 24 of wall 2, so as to connect them.

[0071] The flange 81 of the container 8 is configured to be fixed at the level of the first surface 23 of the wall 2, preferably on the first surface 23 of the wall 2, so that the container 8 extends outside the enclosure 100 but can open onto the enclosure 100, through the opening 20. When the flange 81 is correctly fixed to the wall 2, the inside of the enclosure 80 forms an aseptic airlock between the enclosure 100 and the external environment, which is suitable for collecting components 10 to be transferred from the enclosure 100 to the external environment without breach of containment.

[0072] The wall 2 further delimits a plurality of through orifices, extending between the first surface 23 of the wall 2 and the second surface 24 of the wall 2, so as to connect them, and intended to cooperate with some of the elements of the coupling device 4 and the locking device 5, in a sealed manner in order to prevent any breach of containment of the enclosure 100.

[0073] Door

[0074] Door 3 allows access to enclosure 100 from the outside environment. In this respect, door 3 is movablely mounted on wall 2 between a closed position, in which door 3 closes the opening 20, and an access position in which door 3 does not close the opening 20.

[0075] In the closed position, system 1 forms a continuous partition to confine enclosure 100 and maintain its airtightness. In this respect, an external edge 30 of door 3 matches the internal edge 21 of wall 2, which defines the opening 20. Consequently, the shape and dimensions of door 3 correspond approximately to the shape and, respectively, the dimensions of the opening 20.

[0076] In the access position, the door 3 extends at a distance from the opening 20. In the access position, the door 3 can partially close the opening 20 depending, in particular, on how the door 3 is movable on the wall 2. In the access position, the system 1 allows the transfer of components 10 through the opening 20.

[0077] Preferably, the door 3 is mounted to move on the second surface 24 of the wall 2, so that it can be operated from within the confined enclosure 100. Preferably, the door 3 is mounted to rotate, or pivot, on the wall 2, typically by means of a hinge. The door 3 has a first surface 31 and a second surface 32.

[0078] The first surface 31 of the door 3 is designed to extend towards the external environment in the closed position. In other words, the first surface 31 of the door 3 is located opposite the opening 20 in the closed position. The lid 82 of the container 8 is configured to be coupled to the door 3 at the level of the first surface 31 of the door 3.

[0079] The second surface 32 of the gate 3 is opposite the first surface 31 of the gate 3, in a direction orthogonal to the plane of the gate 3. The second surface 32 of the gate 3 is intended to extend opposite the enclosure 100 in the closed position.

[0080] The system 1 may include a sealing gasket 33 which is interposed between the inner edge 21 of the wall 2 and the outer edge 30 of the door 3 in the closed position, being free or fixed to either of the wall 2 and the door 3, and which is configured to reinforce the sealing of the system 1 in the closed position of the door 3. The sealing gasket 33 may take a shape corresponding to the inner edge 21 of the wall 2 and / or the outer edge 30 of the door 3, typically being a bead delimiting a rectangular contour.

[0081] Coupling device

[0082] The coupling device 4 is configured to hermetically fix the flange 81 of the container 8 against the first surface 23 of the wall 2, in a removable, simple, safe and convenient manner.

[0083] Coupling device 4 has a holding configuration and a release configuration.

[0084] In the holding configuration, the coupling device 4 is configured to hermetically hold the flange 81 of the container 8 against the first surface 23 of the wall 2 of the system 1. The holding configuration corresponds to the situation in which the container 8 is fixed to the system 1.

[0085] In the release configuration, the coupling device 4 is configured to allow separation of the flange 81 of the container 8 and the wall 2 of the system 1. The release configuration corresponds to the situation in which the container 8 can be returned to the system 1 or removed from the system 1.

[0086] The coupling device 4 may include a control element 40 configured to be operated by a user in order to control a transition of the coupling device 4 between the holding configuration and the release configuration.

[0087] The control element 40 of the coupling device 4 is mechanical, which makes its use simple and practical. Preferably, the control element 40 of the coupling device 4 comprises a lever mounted movable, preferably for rotation or pivoting, on the wall 2, advantageously at the first surface 23 of the wall 2. The lever has the advantage of being able to be operated with one hand, the other hand being free, for example, to correctly position the flange 81 of the container 8 on the first surface 23 of the wall 2.

[0088] In one variant, the coupling device 4 may include a motorization system to implement the transition of the coupling device 4 between the holding configuration and the release configuration in an automated manner.

[0089] The coupling device 4 may include a plurality of cams 41 distributed over the first surface 23 of the wall 2 at a periphery of the opening 20.

[0090] Each cam 41 is mounted movable, preferably rotationally, on the wall 2, between a clamping position in which the cam 41 is configured to hermetically hold a portion of the flange 81 against the first surface 23 of the wall 2, and an unlocking position in which the cam 41 is configured to allow separation of the portion of the flange 81 and the wall 2.

[0091] The cams 41 are simple and inexpensive mechanical components to manufacture, which nevertheless possess the properties necessary for secure retention of the flange 81.

[0092] Each cam 41 is in the form of a flat mechanical part, of arbitrary shape, articulated for rotation about an axis fixed to the wall 2, the axis extending orthogonally to the plane of the cam 41, being centered, or not, on the cam 41. It is the internal surface of the cam 41, that is to say extending opposite the first surface 23 of the wall 2, which ensures the maintenance of a portion of the flange 81 in the clamping position.

[0093] The coupling device 4 may further include a linking member 42 connecting the control member 40 of the coupling device 4 to the plurality of cams 41 so that the actuation of the control member 40 of the coupling device 4 causes a transition of the plurality of cams 41, preferably simultaneously, between the clamping position and the unlocking position.

[0094] The connecting member 42 advantageously comprises a plurality of tabs connected to each other and to the cams 41. Preferably, the connecting member 42 comprises one tab per edge of the opening 20, i.e., four tabs in the case of a rectangular opening 20. Furthermore, at least some of the cams 41 are connected to several, preferably at least two, adjacent tabs, so as to transmit movement from one tab to another. These cams 41 are, in the case of a rectangular opening 20, positioned at the four corners of the opening 20. Each tongue extends in the same plane as the cams 41 and is connected to each cam 41 by means of at least one pin extending orthogonally to the plane of the cam 41 and the tongue to articulate the cam 41 in rotation relative to the tongue so as to transmit the movement of the control member 40 of the coupling device 4 to the cams 41.

[0095] Furthermore, the coupling device 4 may include a locking member 43 configured to cooperate with the locking device 5. Advantageously, the locking member 43 includes a pin connected to the linking member 42 of the coupling device 4, in this case to one of the tabs extending over one of the edges of the opening 20, preferably the edge extending opposite the locking device 5.

[0096] Locking device

[0097] The locking device 5 allows the door 3 to be locked in its closed position to prevent accidental breach of containment. In this respect, the locking device 5 has a locking configuration and an unlocking configuration.

[0098] In the locking configuration, the locking device 5 holds the door 3 in the closed position.

[0099] In the unlocked configuration, the locking device 5 allows the door 3 to transition from the closed position to the access position. In the unlocked configuration, the enclosure 100 is accessible for the transfer of components 10 into the container 80.

[0100] The locking device 5 may include a control element 51 configured to be operated by a user to control a transition between the locking configuration and the unlocking configuration.

[0101] The control element 51 of the locking device 5 is mechanical, which makes its use simple and convenient.

[0102] Preferably, the control element 51 of the locking device 5 is mounted on the door 3.

[0103] Advantageously, the locking control element includes a lever movably mounted on the door 3, preferably at the level of the second surface 32 of the door 3. The lever has the advantage of being able to be manipulated with one hand, the other hand being free, for example, to carry the components 10 to be transferred.

[0104] In one variant, the locking device 5 may include a motorization system to implement the transition of the locking device 5 between the locking configuration and the unlocking configuration in an automated manner.

[0105] The locking device 5 may include a strike plate 52 and a bolt 53.

[0106] The bolt 53 is connected, preferably in a rigid manner, to the control mechanism and configured to cooperate with the strike plate 52, in the locking configuration, in order to keep the door 3 in the closed position.

[0107] The strike plate 52 is preferably fixedly mounted on the second surface 24 of the wall 2. The use of a strike plate 52 and a bolt 53 allows for a practical, robust and secure locking, while being of simple design and inexpensive to manufacture.

[0108] The locking device 5 is further configured to couple the lid 82 of container 8 to the door 3 of system 1. More specifically, a transition of the locking device 5 from the locking configuration to the unlocking configuration results in coupling the lid 82 to the door 3, while a transition of the locking device 5 from the unlocking configuration to the locking configuration results in decoupling the lid 82 from the door 3. This dual functionality of the locking device 5 is convenient and further enhances the security of system 1.

[0109] In this regard, the locking device 5 may include a coupling member 55 and a transmission member 56.

[0110] The coupling member 55 is configured to couple the cover 82 to the door 3.

[0111] The transmission member 56 cooperates with the coupling member 55 and the control member 51 of the locking device 5 so that an actuation of the control member 51 of the locking device 5 to command a transition of the locking device 5 from the locked configuration to the unlocked configuration results in a coupling of the cover 82 to the door 3 by the coupling member 55. In this way, the actuation of the control member 51 of the locking device 5 allows, at the same time, the opening of the door 3 and access to the interior of the casing 80 of the container 8.

[0112] In one embodiment, the transmission member 56 is a toothed member mounted movable relative to the gate 3 while preferably being integrated into the gate 3, that is to say arranged within a cavity made in the thickness of the gate 3, the cavity not being in communication with the outside of the gate 3.

[0113] The toothed member engages a gear fixed to the control member 51 of the locking device 5, which makes it possible to multiply the effort produced by the user when actuating the control member 51 of the locking device 5.

[0114] The toothed element, moreover, is connected, preferably mechanically, to the coupling element 55.

[0115] Typically, the toothed element is a wheel that rotates relative to the gate 3 on the same axis as the coupling element 55, being rotationally fixed to the coupling element 55. Alternatively, the toothed element can be a portion of a toothed wheel comprising a straight area including a rotating stop element.

[0116] To improve the safety of system 1, it is advantageous that the locking device 5 cannot be operated until the flange 81 is properly fixed to the wall 2, and also that the flange 81 cannot be detached from the wall 2 while the door 3 is in the access position, in a simple, practical, and inexpensive manner. In this way, there is no risk of a breach of containment during the use of system 1.

[0117] In this respect, the coupling device 4 is configured to cooperate with the locking device 5 so as to prevent the locking device 5 from transitioning from the locked to the unlocked position, as long as the coupling device 4 is in the released position, or rather, as long as the coupling device 4 is not in the held position. Thus, as long as the flange 81 is not properly fixed to the wall 2, the locking device 5 is blocked.

[0118] Furthermore, the locking device 5 is configured to cooperate with the coupling device 4 in such a way as to prevent the coupling device 4 from transitioning from the holding position to the release position, as long as the locking device 5 is in the unlocking position, or rather, as long as the locking device 5 is not in the locking position. Thus, as soon as the door 3 is free to move from the closed position to the access position, the coupling device 4 is locked in its holding position, and the flange 81 is not at risk of detaching from the wall 2.

[0119] In one embodiment, the locking device 5 includes a locking member 54 which has a first configuration and a second configuration.

[0120] In the first configuration, the locking member 54 prevents a transition of the coupling device 4 from the holding configuration to the release configuration, preferably by cooperation with the blocking member 43 of the coupling device 4.

[0121] In the second configuration, the locking member 54 allows a transition of the coupling device 4 from the holding configuration to the release configuration.

[0122] However, when the coupling device 4 is in the release configuration, the locking member 54 cooperates with the locking member 43 of the coupling device 4 to maintain the locking device 5 in the locked configuration. In this respect, the locking member 54 includes a portion extending from the first surface 23 of the wall 2, which advantageously takes the form of a cam equipped with a hook configured to cooperate with the pin of the locking member 43. Thus, it is only in the holding configuration that the locking member 43 allows the locking member 54 to transition from its second configuration to its first configuration. Furthermore, the locking member 54 is configured to cooperate with the control member 51 of the locking device 5 to bring about a transition between the first and second configurations.

[0123] The locking member 54 may include a first portion 541, a second portion 542 and a linking portion 540.

[0124] The first portion 541 extends from the first surface 23 of the wall 2 and is configured to cooperate with the coupling device 4. The first portion 541 corresponds to the cam equipped with a hook in the preferred embodiment.

[0125] The second portion 542 extends from the second surface 24 of the wall 2 and is configured to cooperate with the control organ 51 of the locking device 5.

[0126] The connecting portion 540 links the first portion 541 to the second portion 542, has a principal direction, preferably substantially orthogonal to the plane of the wall 2, and extends within one of the openings provided through the wall 2 for this purpose. The connecting portion 540 is substantially barrel-shaped. The locking member 54 is rotationally movable relative to the wall 2 around the principal direction of its connecting portion 540.

[0127] An O-ring can be arranged within the orifice to prevent fluid circulation between the confined enclosure 100 and the outside around the connecting portion 540 of the locking member 54.

[0128] When the door 3 is in the closed position and the coupling device 4 is in the release configuration, the blocking member 43 of the coupling device 4 cooperates with the locking member 54 of the locking device 5 to prevent the actuation of the control member 51 of the locking device 5. This makes it possible to prevent the transition of the door 3 between its closed position and its access position as long as the flange 81 of the container 8 is not hermetically fixed to the wall 2: the confined enclosure 100 is only accessible when the container 8 is correctly fixed to the system 1.

[0129] When the door 3 is in the closed position and the coupling device 4 is in the holding configuration, the locking member 43 of the coupling device 4 releases the locking member 54 of the locking device 5 to allow the actuation of the control member 51 of the locking device 5. This allows the transition between the closed position and the access position, the flange 81 of the container 8 being then hermetically fixed to the wall 2: the manipulation of the door 3 is only possible when the container 8 is correctly fixed to the system 1.When door 3 is in the access position and locking device 5 is in the unlocked configuration, the locking member 43 of coupling device 4 cooperates with the locking member 54 of locking device 5 to prevent coupling device 4 from transitioning from the holding to the release configuration, i.e., to lock coupling device 4 in the holding configuration. This prevents the flange 81 from detaching from wall 2 as long as door 3 is in the access position: the user cannot remove container 8 from system 1 until the confined enclosure 100 is hermetically sealed by door 3.

[0130] Safety device

[0131] The safety device 6 prevents decoupling between the lid 82 of the container 8 and the door 3, as long as the door 3 is in the access position.

[0132] The safety device 6 comprises a first safety element 61 and a second safety element 62.

[0133] The first safety device 61 is arranged at the wall 2, preferably being integrated into the wall 2, that is to say housed within a non-through opening made within the first surface 23 of the wall 2. Advantageously, the first safety device 61 includes a magnetic element 610.

[0134] The second safety device 62 is arranged at the level of door 3.

[0135] The second safety component 62 cooperates with the locking device 5.

[0136] The second safety device 62 has a blocking configuration and an unlocking configuration.

[0137] In the blocking configuration, the second safety element 62 prevents a transition of the locking device 5 from the unlocking configuration to the locking configuration, so as to keep the cover 82 coupled to the door 3.

[0138] In the unlocking configuration, the second safety device 62 allows a transition of the locking device 5 from the unlocking configuration to the locking configuration, so as to allow a decoupling of the cover 82 from the door 3.

[0139] The safety device 6 is configured so that a transition of the second safety element 62 from the blocking to the unlocking configuration is triggered by cooperation, preferably magnetic, between the first safety element 61 and the second safety element 62, when the door 3 is in the closed position. Preferably, the safety device 6 is configured so that a transition of the second safety element 62 from the blocking to the unlocking configuration, by cooperation with the first safety element 61, is only possible when the door 3 is in the closed position. In other words, the safety device 6 is configured to prevent cooperation between the first safety element 61 and the second safety element 62 as long as the door 3 is in the access position.In this way, as long as door 3 is in the access position, the safety device 6 remains in the blocking configuration, which prevents the decoupling of the lid 82 of the container 8 and the door 3, thus strengthening the safety of system 1 in a simple, practical and inexpensive way.

[0140] Advantageously, the second safety element 62 cooperates with the transmission element 56 of the locking device 5. In this respect, the second safety element 62 may include a gear meshing with the toothed wheel of the transmission element 56.

[0141] In one embodiment, the second safety device 62 comprises a support 620, a locking element 621, a return element 622 and a magnetic element 623, preferably all integrated into the door 3.

[0142] The support 620 cooperates with the locking device 5. Typically, the support 620 is integral with the gear meshing the toothed wheel of the transmission member 56. The support 620 is mounted movable, advantageously in rotation, or pivoting, relative to the door 3. A light 6200 is provided in the support 620 and includes a guide portion 62001 and a stop portion 62002, the stop portion 62002 having a cross-section greater than the guide portion 62001.

[0143] The locking element 621 is movable, advantageously in translation in a direction orthogonal to the plane of the door 3, and comprises a head 6211 and a shoulder 6212. The head 6211 is configured to cooperate with the guide portion 62001 of the opening 6200 so as to guide the movement of the locking element 621 relative to the support 620, thus forming a sliding joint. The shoulder 6212 is configured to cooperate with the stop portion 62002 of the opening 6200 so as to block the movement of the locking element 621 relative to the support 620.

[0144] The return element 622 is configured to stress the locking element 621 in the direction of the support 620. Typically, the return element 622 is a helical spring.

[0145] The magnetic element 623 is connected to the locking element 621 and configured to stress the locking element 621 in a direction opposite to the support 620 when the magnetic element 623 is stressed by a magnetic field, typically that of the magnetic element 610 of the first safety device 61 when the door 3 is in the closed position.

[0146] Thus, when the door 3 is in the closed position, the locking element 621 is magnetically attracted by the first safety member 61, against the force exerted by the return member 622. The second safety member 62 is then in the unlocking configuration, in which the support 620 is free to rotate relative to the door 3 since the head 6211 of the locking element 621 is free to run within the light 6200 of the support 620, and therefore the control member 51 of the locking device 5 is free to be actuated. When the control member 51 of the locking device 5 is actuated, the support 620 pivots relative to the door 3, the head 6211 of the locking element 621 moving within the guide portion 62001 of the light 6200 of the support 620 until it cooperates with the stop portion 62002 of the light 6200 of the support 620.

[0147] As soon as the door 3 leaves the closed position, the magnetic force exerted by the first safety device 61 on the locking element 621 becomes less than the force exerted by the return element 622, which then pushes the head 6211 and the shoulder 6212 of the locking element 621 into the stop portion 62002 of the opening 6200 of the support 620. The second safety device 62 is then in the locked configuration, in which any movement of the support 620 relative to the door 3 is prevented by the engagement of the head 6211 and the shoulder 6212 of the locking element 621 with the stop portion 62002 of the opening 6200 of the support 620. Consequently, any actuation of the control element 51 of the locking device 5 is also prevented, thus preventing the disengagement between the lid 82 of container 8 and door 3.

[0148] No element of the safety device 6 protrudes from the door 3 or the wall 2; preferably, all its elements are integrated into one or the other of the door 3 and the wall 2, i.e., housed within cavities provided for this purpose within one or the other of the door 3 and the wall 2. The use of magnetic elements facilitates such integration, allowing the first safety device 61 to interact with the second safety device 62 without direct contact. Consequently, cleaning of the system 1 is made easier.

[0149] Stopping device

[0150] The stop member 7 prevents the actuation of the control member 51 of the locking device 5 until the flange 81 of the container 8 is properly fixed to the wall 2.

[0151] The stop 7 therefore provides additional security compared to the combined operation of the locking device 43 and the locking device 54, when the door 3 is in the closed position and the coupling device 4 is in the released position. The stop 7 is rotatably mounted on the wall 2.

[0152] The stop 7 is further coupled to the coupling device 4 so that, when the coupling device 4 is in the release configuration, the stop 7 cooperates with the locking device 5 to prevent actuation of the control element 51 of the locking device 5, and, when the coupling device 4 is in the holding configuration, the stop 7 allows actuation of the control element 51 of the locking device 5. In this way, the locking device 5 can only be actuated when the flange 81 of the container 8 is correctly fixed to the first surface 23 of the wall 2. The safety and sealing of the system 1 are thus improved in a simple and practical manner.By being configured to allow, or prevent, the actuation of the control member 51 of the locking device 5, and not of the door 3, the stop member 7 improves the ability of the system 1 to be cleaned, by limiting dead spaces that cannot be reached by sterilization when the door 3 is in the closed position.

[0153] In one embodiment, the stopping member 7 comprises a first portion 71, a second portion 72, a connecting portion 70 and a sealing member.

[0154] The first portion 71 of the stopping member 7 extends from the first surface 23 of the wall 2 and is coupled to the coupling device 4, preferably to the linking member 42 of the coupling device 4.

[0155] The second portion 72 of the stopping member 7 extends from the second surface 24 of the wall 2 and is configured to cooperate with the locking device 5, preferably with the bolt 53 of the locking device 5.

[0156] The connecting portion 70 of the stop 7 links the first portion 71 of the stop 7 to the second portion 72 of the stop 7, has a principal direction, and extends within one of the orifices provided in the wall 2 for this purpose. The stop 7 is rotationally movable relative to the wall 2 around the principal direction of its connecting portion 70. The sealing element is arranged within the orifice and positioned between the connecting portion 70 and the wall 2 so as to prevent fluid flow through the orifice from the first surface 23 of the wall 2 to the second surface 24 of the wall 2. The sealing element is typically an O-ring.

[0157] Since the retaining element 7 is rotationally mobile, and not translationally mobile, relative to the wall 2, sealing through the wall 2 is much easier to achieve. Furthermore, each of the first portion 71 and the second portion 72 of the retaining element 7 is always exposed to the same environment, which facilitates cleaning, unlike a retaining element 7 that would translate in a direction orthogonal to the wall 2 and have some of its faces transition from the confined environment to the outside. Retaining device

[0158] The retaining device 9 is configured to prevent the flange 81 from separating from the wall 2 as long as the door 3 is in the access position.

[0159] The retaining device 9 therefore offers additional security compared to the cooperation of the locking device 5 with the coupling device 4 in the unlocking configuration of the locking device 5.

[0160] The restraint device 9 comprises a first restraint element 91 and a second restraint element 92.

[0161] The first retaining device 91 is arranged at the level of the door 3, preferably being integrated into the door 3. Advantageously, the first retaining device 91 includes a magnetic element 910.

[0162] The second retaining device 92 is arranged at the level of the wall 2. Advantageously, the second retaining device 92 is housed in a non-through opening made at the level of the first surface 23 of the wall 2.

[0163] The second retaining device 92 has an engagement configuration and a disengagement configuration.

[0164] In the engagement configuration, the second retaining element 92 cooperates with the coupling device 4 so as to prevent a transition of the coupling device 4 from its holding configuration to its release configuration.

[0165] In the disengagement configuration, the second retaining element 92 allows a transition of the locking device 4 from the holding configuration to the release configuration, so as to allow a separation of the flange 81 from the wall 2.

[0166] The retaining device 9 is further configured such that cooperation between the first retaining element 91 and the second retaining element 92 results in a transition of the second retaining element 92 from the engaged to the disengaged configuration. Preferably, the retaining device 9 is configured such that a transition of the second retaining element 92 from the engaged to the disengaged configuration, through cooperation with the first retaining element 91, is only possible when the door 3 is in the closed position. In other words, the retaining device 9 is configured to prevent cooperation between the first retaining element 91 and the second retaining element 92 as long as the door 3 is in the access position.

[0167] In this way, as long as the door 3 is in the access position, the retaining device 9 remains in the engagement configuration, which prevents the flange 81 from detaching from the wall 2, thus reinforcing the safety of system 1 in a simple, practical and inexpensive way.

[0168] In one embodiment, the second safety device 92 comprises a retaining element 921, a return element 922 and a magnetic element 923, preferably all housed in the non-through opening made at the level of the first surface 23 of the wall 2.

[0169] The retaining element 921 cooperates with the coupling device 4 in the engaged configuration to prevent actuation of the control member 40 of the coupling device 4. Preferably, the retaining element 921 cooperates with the connecting member 42 in the engaged configuration. To achieve this, the retaining element 921 may include a pin 9211 configured to cooperate with a through or non-through orifice 420 provided in the connecting member 42 in the engaged configuration. The orifice 420 is positioned on the connecting member 42 so as to be opposite the retaining element 921 when the coupling device 4 is in its holding configuration. In this way, the coupling device 4 is prevented from switching from its holding configuration to its release configuration in a simple, practical, and inexpensive manner.The retaining element 921 is mounted movable, advantageously in translation in a direction orthogonal to the plane of wall 2, with respect to wall 2.

[0170] The return element 922 is configured to stress the retaining element 921 towards the coupling device 4, and more particularly towards the connecting member 420. Typically, the return element 922 is a helical spring.

[0171] The magnetic element 923 is connected to the retaining element 921 and configured to stress the locking element 921 in a direction opposite to the coupling device 4 when the magnetic element 923 is stressed by a magnetic field, typically that of the magnetic element 910 of the first retaining member 91 when the door 3 is in the closed position.

[0172] Thus, when the door 3 is in the closed position, the retaining element 921 is magnetically attracted by the first retaining member 91, against the force exerted by the return member 922. The second safety member 92 is then in the disengagement configuration, in which the linking member 42 is free to reposition the cams 41 relative to the wall 2 since the pin 9211 of the retaining element 921 does not cooperate with the orifice 420 of the linking member 42, and therefore the control member 40 of the coupling device 4 is free to be actuated.

[0173] As soon as the door 3 leaves the closed position, the magnetic force exerted by the first retaining member 91 on the retaining element 921 becomes less than the force exerted by the return element 922, which then pushes the pin 9211 of the retaining element 921 into the orifice 420 of the connecting member 42. The second retaining member 92 is then in the engaged configuration, in which any movement of the connecting member 42 relative to the wall 2 is prevented by the interaction of the pin 9211 and the orifice 420 of the connecting member 42. Consequently, any actuation of the control member 40 of the coupling device 4 is also prevented, thus preventing the flange 81 from the container 8 from the wall 2.

[0174] No element of the retaining device 9 protrudes from the door 3 or the wall 2; preferably, all its elements are integrated into one or the other of the door 3 and the wall 2, i.e., housed within cavities provided for this purpose within one or the other of the door 3 and the wall 2. The use of magnetic elements facilitates such integration, allowing the first retaining element 91 to interact with the second retaining element 92 without direct contact being necessary. Consequently, cleaning of the system 1 is made easier.

[0175] System operation

[0176] The use of system 1 can be implemented by a single user, typically when enclosure 100 is a glove box, or by several users. Typically, when enclosure 100 is a cleanroom, in a first step implemented outside enclosure 100, container 8 and coupling device 4 can be manipulated, and in a second step implemented inside enclosure 100, locking device 5 is manipulated; the first and second steps can be implemented by the same user or different users.

[0177] With the door 3 in the closed position, the locking device 5 in the locked configuration, the coupling device 4 in the released configuration, and the second retaining element 92 in the disengaged configuration, the flange 81 of a container 8 is positioned on the first surface 23 of the wall 2, at the cams 41, conforming to the contour of the opening 20. The lid 82 is then attached to the flange 81. The locking device 5 cannot be actuated because the blocking element 43 cooperates with the locking element 54, which is in the second configuration. Furthermore, the stop element 7 prevents the actuation of the control element 51 of the locking device 5.

[0178] Once the flange 81 is correctly positioned, the control member 40 of the coupling device 4 is actuated so that the coupling device 4 moves into its holding configuration, securing the flange 81 against the wall 2. At the same time, the locking member 43 releases the locking member 54, which can then move into the first configuration, allowing the locking device 5 to unlock the door 3. Furthermore, the stop member 7 releases the control member 51 of the locking device 5. Finally, the orifice 420 of the connecting member is aligned with the retaining element 921 of the second retaining member 92 of the retaining device 9.

[0179] The control element 51 of the locking device 5 is then actuated, allowing the door 3 to move from its closed position to its access position. Simultaneously, the lid 82 of the container 8 is coupled to the first surface 31 of the door 3 and disengages from the flange 81. Furthermore, the interaction of the blocking element 43 and the locking element 54, which has moved into its initial configuration by the actuation of the control element 51 of the locking device 5, prevents the flange 81 from disengaging from the wall 2 by preventing the coupling device 4 from returning to its release configuration.

[0180] The door 3 is then manipulated to move into its access position, which triggers the safety device 6 and locks the control member 51 of the locking device 5, thus preventing any separation of the lid 82 of the container 8 and the door 3. In addition, the second retaining member 92 moves into the engagement configuration, which locks the control member 40 of the coupling device 4, thus preventing any separation of the flange 81 from the wall 2. The interior of the container 80 is accessible from the enclosure 100 and components 10 can be placed there.

[0181] Once all the components 10 are arranged in the envelope 80, the door 3 is manipulated to return to its closed position, which causes the disarming of the safety device 6, again allowing the manipulation of the control member 51 of the locking device 5, and the disarming of the retaining device 9 again allowing the manipulation of the control member 40 of the coupling device 4.

[0182] The control member 51 of the locking device 5 is then actuated to move the locking device 5 from its unlocked position to its locked position, thus securing the door 3 in its closed position in a watertight manner. The locking member 54 thus moves from its first to its second configuration, releasing the coupling device 4, and more specifically the locking member 43, which can return to its released position. Furthermore, the cover 82 is decoupled from the door 3 and reattached to the flange 81 in a watertight manner.

[0183] The control element 40 of the coupling device 4 is then actuated to move the coupling device 4 from the holding position to the release position. This releases the flange 81, and thus the container 8 containing the components 10, in a sealed manner. Furthermore, this prevents the actuation of the control element 51 of the locking device 5, thanks to the stop element 7 and the interaction of the blocking element 43 and the locking element 54, which is in its second position, thereby preventing the door 3 from reopening.

[0184] This use of system 1 can be repeated as many times as necessary, in a simple, practical and safe manner, without risk of breach of containment, thanks in particular to the numerous safety mechanisms preventing any accidental manipulation of system 1. Cleaning of system 1 can be carried out without having to dismantle it, typically by spraying gas and / or cleaning and / or sterilizing agents on the protruding surfaces of system 1.
