Definitions

  • the present invention relates to a device for sealing connection between two enclosures.
  • the term "enclosure” here designates a container or a chamber or a room, equipped with an access means sealingly closed.
  • This container, this room or room defines a volume of preparation, storage and / or manipulation of products not to be in contact with the outside or with a user. These are, for example, dangerous products such as certain biological, chemical or radioactive products.
  • Such an enclosure makes it possible to perform certain manipulations on these products, without the manipulator being in direct contact with the products. Handling is carried out by means of tools or gloves, fixed on the enclosure. The manipulations of the products are thus achieved by isolating the interior of the enclosure vis-à-vis the outside.
  • One of the speakers to be connected may, for example, be a container-type waste collection container.
  • a handling enclosure In order to access the interior of a handling enclosure, it is provided with a flange, which delimits a through opening connecting the inside and the outside of the enclosure and which carries a door movably sealing of the aforementioned opening.
  • This door is generally maneuverable by the user from inside the enclosure. It is appropriate, when it is desired to connect two speakers of the same or different kinds, to ensure a connection avoiding any pollution vis-à-vis the outside. For this, it is known to connect the doors of two speakers contiguously, with interposition of a minimum air mattress between the two connected doors.
  • the sterility of a handling chamber must also be preserved when connecting the enclosure to a waste container type container, to evacuate certain products out of the handling chamber.
  • connection device which is provided for assembling the respective flanges of two enclosures to be connected to one another by means of the engagement of the two flanges with each other and the rotary drive of one of the flanges relative to the other: during this assembly, on the one hand, the two flanges bind to one another, typically by the engagement of a bayonet system, and, on the other hand, the door of one of the two enclosures are fixedly attached to the door of the other enclosure, typically by the engagement of a bayonet system, while disengaging from its associated flange, typically by the disengagement of a bayonet system which, until then, held this door in the closed position on this flange.
  • the known device also comprises a handle for locking the door of the other enclosure with respect to its corresponding flange: this handle must be moved by the user to allow this door free to be moved in order to open it vis-à-vis its flange associated.
  • FR-A-2 981 386 proposes to reinforce the safety of this kind of device, by equipping it with a locking mechanism of the locking handle: this mechanism is intended to prohibit, in the absence of the assembly of the two flanges with each other, to move the locking handle from its position of immobilization of the corresponding door.
  • This mechanism comprises two rods movable in translation parallel to the centering axis of the flanges, namely a high stem, carried by the locking handle, and a low stem, carried by the flange on which the handle is mounted movably.
  • the lower rod occupies, by gravity, the bottom of a bore of the aforementioned flange so that, when the locking handle is in a closed position of the corresponding door, the upper rod is aligned with the lower rod and blocks any rotation of the locking handle extending across the joint plane between the flange and the handle, a spring, interposed between the upper stem and the body of the handle, acting on the upper stem downwards to hold it against the upper end of the lower stem.
  • the blocking mechanism of FR-A-2 981 386 has disadvantages.
  • the central axis of the flange is oriented vertically. or approximately vertically, otherwise the lower rod is not able to fall, by gravity, into the bottom of the aforementioned bore.
  • the stiffness of the spring, interposed between the upper rod and the body of the locking handle, is necessarily limited because, as soon as the handle leaves its closed position of the corresponding door to open the latter, this spring presses the upper rod against the upper face of the aforementioned flange: it is understood that excessive stiffness of this spring will hinder or even prevent the rotation of the handle 36, because of the friction of the lower end of the upper stem against the upper face of the aforementioned flange.
  • the aforementioned spring is weak, the risk of neutralization, accidental or malicious, of the locking mechanism of FR-A-2 981 386 is real.
  • the object of the present invention is to provide a connection device of the type mentioned above, which is improved by strengthening the security, while being simple to manufacture and easy to maneuver.
  • the invention relates to a device for sealing connection between two enclosures, as defined in claim 1.
  • One of the basic ideas of the invention is to seek to block any movement of the locking handle of the first door as the first flange is not assembled with the second flange.
  • the invention provides that, during the assembly of the two flanges with each other, that is to say during the centering of these flanges on a common axis and then their relative displacement in rotation around this common axis to both bind the two flanges together, bind the two doors to one another and separate the second door from the second flange, the second flange acts mechanically on a specific actuator, which belongs to an ad hoc mechanism carried by the first flange and which controls the locking in position of the locking handle.
  • the blocking produced by the mechanism according to the invention can be provided particularly strong, in the sense that the elastic member, which is interposed fixedly, and therefore permanently, between the first flange and the actuator and which maintains this actuator in a position blocking the locking handle, is advantageously provided steep, or very stiff: this substantially limits the risk of neutralization, accidental or malicious, the blocking action by the aforementioned mechanism, since such neutralization would require to apply on the actuator a force strong enough to overcome the resistance of this elastic member.
  • the torque applied by the user to the second flange to assemble it to the first flange can develop, without difficulty for the user, a sufficient force on the actuator to counteract the action of this elastic member, compressing the latter between the actuator and the first flange.
  • the rotary assembly between the two flanges around their common axis, to control both the attachment of these two flanges to one another, the attachment of the two doors to one another and the separation between the second door and the second flange, typically by the implementation of bayonet systems, is used to mechanically control the locking mechanism according to the invention, more precisely to control the displacement of the actuator of this mechanism in translation parallel to the common axis, by opposing the action of the elastic member, for the purpose of unlocking the locking handle.
  • connection device By prohibiting the ability to move the locking handle to open the first door until the first speaker is properly connected to the second speaker, the connection device according to the invention has enhanced security without inducing for the user specific manipulations to release the locking handle, other than the assembly of the two flanges to one another.

  • the two parts of the fixing means 51, respectively carried by the flanges 20 and 40 engage axially with each other and, on the other hand, the parts of the means 52, respectively carried by the doors 10 and 30, engage axially with each other: in the embodiment considered in the figures, that is to say that the tabs 42 of the flange 40 s' each engage, in the direction of the axis ZZ, between two successive grooves of the grooves 21 of the flange 20, and that the tabs 33 of the door 30 each engage, in the direction of the axis ZZ, between two successive grooves among the grooves 18 of the door 10.
  • connection device is as shown in FIGS. Figures 1 to 3 , 6 and 7 .
  • the flange 40 does not interfere with the actuator 85, so that, as explained above, the mechanism 80 blocks the locking handle 70 in its position of immobilizing the door 10 in position closed.
  • the flange 40 is then rotated about the axis ZZ, as indicated by the arrow F on the figures 3 and 6 , until passing the connection device in the assembly configuration that is mounted on the figures 5 and 8 to 11 .
  • the unlocking of the locking handle 70 is only performed at the end of the rotary stroke of the flange 40 with respect to the flange 20, typically in the second half of the aforementioned rotary stroke, or even in the third third of this rotary stroke: in this way, as the flange 40 has not reached its end of rotary stroke relative to the flange 20, the locking handle 70 remains locked in its position of immobilization of the door 10, by the locking mechanism 80.
  • this advantageous arrangement is implemented, providing that the actuator 85 is located in one of the grooves 21, being further from the end of this groove, through which is introduced the corresponding tab 42 of the flange 40, that its opposite end, in which abuts this tab when the connection device reaches its assembly configuration.
  • the user moves the locking handle 70 in rotation about the axis Z70, as indicated by the arrow G on the figure 8 , thus passing it from its position of immobilization of the door 10 in the closed position, to its position of release of this door 10, shown on the Figures 12 and 13 .
  • the rotation of the locking handle 70 induces the opening of the door 10 and therefore the door 30 which is secured to it, by rolling contact contact or sliding between the ramp surface 75 and the body 110 .
  • connection device comprises means for securing the assembly of the flanges 20 and 40, that is to say of secure the securing means 51, prohibiting disassembly of the flanges 20 and 40 when the door 10 is not in its closed position.
  • these securing means comprise two fingers 90 and 91, each designed to block the relative rotation between the flanges 20 and 40.
  • the finger 90 is more specifically visible on the fingers. figures 10 , 14 and 15 , while the finger 91 is more specifically visible on the figures 11 and 16 .
  • Each of the fingers 90 and 91 is carried by the flange 20 movably in translation parallel to the axis ZZ, between a retracted position, which is represented on the figure 10 for the finger 90 and on the figure 11 for the finger 91, in which the finger 90, 91 does not interfere with the fastening means 51, thus freely allowing the portions of these means, respectively carried by the flange 20 and the flange 40, to be engaged and withdrawn, and an unfolded position, which is shown on the figures 14 and 15 for the finger 90 and on the figure 16 for the finger 91, in which the finger 90, 91 is mechanically opposed to the relative rotation of the flanges 20 and 40, in particular whereas these flanges 20 and 40 are fixedly connected to one another by the means
  • each of these fingers 90 and 91 forms a stop at one of the tabs 42 of the flange 40 while this tab is disposed at the inside one of the grooves 21 of the flange 20.
  • Each of the fingers 90 and 91 is associated with a compression spring 92, 93, which is interposed between the corresponding finger and the flange 20.
  • the spring 92 acts on the finger 90 to maintain it in its deployed position while a force overcoming the action of the spring is not applied, antagonistically, on the finger 90.
  • the spring 93 acts on the finger 91 to recall it from its deployed position to its retracted position in the absence of antagonistic effort applied to the finger 91.
  • the fingers 90 and 91 are diametrically opposed to each other with respect to the axis ZZ: the finger 90 is thus located in the peripheral portion of the flange 20, in which the door 10 is connected at the flange 20 by the hinge mechanism 12, while the finger 91 is located in the peripheral portion of the flange 20, in which the locking handle 70 is arranged on this flange.
  • the respective displacements of the fingers 90 and 91, from their deployed position to their retracted position, are independent of one another, that is to say that they are controlled by own arrangements of the connection device. More specifically, the finger 90 is designed to be moved from its deployed position to its retracted position by the door 10, counteracting the action of the spring 92, when the latter moves from its open position to its closed position, more precisely by the arm 14 of the hinge mechanism 12, linking the main body 13 of the door 10 to the flange 20. It is understood that when the connection device is in the assembly configuration of the figures 5 and 8 to 11 , the door 10 keeps the finger 90 in the retracted position by axial support of its arm 14 against this finger 90, counteracting the action of the spring 92. As soon as the door 10 has moved from its closed position to its open position, the axial support of its arm 14 on the finger 90 stops, moving the finger from its retracted position to its deployed position, under the action of the spring 92.
  • the finger 91 is, in turn, designed to be moved from its retracted position to its extended position by the locking handle 70, by compressing the return spring 93, when the latter moves from its immobilization position to its position of release of the door 10.
  • the body 71 of the handle 70 delimits, in hollow in its axial face facing the flange 20, a groove 77 which has a helical bottom centered on the axis Z70: the finger 91 emerges in the groove 77 until it bears against the bottom of the latter under the action of the spring 93, it being specified that the depth of this groove 77 is, at the axial plumb with the finger 91, progressively decreasing as as the locking handle 70 moves from its immobilization position to its release position of the door 10.
