    [0001] The present invention relates to a quick coupling for the detachable joining of two pipes traversed by a fluid.
    [0002] The quick couplings are adapted to polluted environments and make it possible to connect flexible conduits in systems subjected to vibrations, in particular motorized machines equipped with pipes in inaccessible places. In the field of vehicles, in particular military gear, quick couplings are used to supply subsystems with water, fuel, air or gas via various pipelines. Patent FR-B-2 865 259 discloses a quick connector which comprises two male and female elements own axially slip and causing the opening of a valve mounted in the body of the female element. This body is equipped with a loaded latch, slidably mounted in the body and pierced with a central opening for the fitting of the male element. The lock is bipartite and an axially loaded safety member is able to lock the lock. To disconnect the male element and the female element, it is necessary to exert additional force fitting to further depress the male element in the female element, then exert a force on the latch. Thus, the unlocking of the male and female elements is complicated and requires the use of both hands of the user, in a maneuvering space often restricted. Moreover, when the male and female elements are fitted, the vibrations to which the connection is subjected tend to move the movable elements of the coupling by inertia effect. These parasitic movements may cause the locking mechanisms in an unlocked position, in which the male element is free to exit the female element. FR-A-1 487 324 discloses a lock fitting which is equipped with a locking bolt bolt in its locked position. To disconnect the elements of the coupling, it is necessary first to exert an action on the stud to unlock the lock, then unlock the two coupling elements. Thus, to unmount the male and female elements, it is necessary to perform two successive maneuvers according to two separate maneuvering axes. In addition, the connection according to FR-A-1 487 324 does not incorporate a protective cover preventing the intrusion of pollutants because the stud must remain accessible, which is detrimental to the life of the connection.
    [0003] It is these disadvantages that the invention intends to remedy more particularly by proposing a quick coupling whose disconnection is easy, and to integrate an effective sealing system to protect the connection in polluted environments. For this purpose, the subject of the invention is a quick coupling for the detachable connection of two pipes traversed by a fluid, the connection comprising a male part and a female element able to fit into one another along an axis. longitudinal. The female element is equipped with: - a locking device slidably mounted in a body of the female element according to a radial axis and pierced with at least one opening for the fitting of the male part. A wall of the opening is equipped with a first retaining means. The locking device is movable between: a first position in which the first retaining means is adapted to cooperate with a second corresponding retaining means of the male part for retaining the male part in the female element at a first depth of fitting into a fitted configuration of fluid passage, - a second position in which the locking device allows the male part to release from the female element out of the first fitting depth, - a safety device able to maintain the locking device in its first position when the male part is in a configuration fitted into the female element. When the locking device is in its first position an action on the safety device along the radial axis releases the locking device from its first position. Thanks to the invention, an action on the safety device allows, in a single gesture and with one hand, to unlock the locking device, automatically causing the output of the male element out of the female element. The security device is incorporated within the locking device so that it remains compact. Such a safety device is adapted to the establishment of a protective cover around the mouth of the female element and the safety device, which protects the connection of intrusions of dust and foreign bodies. According to advantageous but non-mandatory aspects of the invention, such a coupling may incorporate one or more of the following features, taken in any technically permissible combination: - The safety device comprises a safety member slidably mounted on a shaft extending perpendicular to the radial axis. The safety member is movable between: a first position in which the locking device locks the male part and the female element in a fitted configuration and in which the safety member is able to bear radially on the male part on a zone diametrically opposed to the first retaining means and a second position in which the safety member does not rest on the male part. The safety device comprises elastic means which tend to push the safety member into its first position. - The safety device comprises a button partially housed in the locking device and movable along the radial axis in the locking device. - The action exerted on the button causes the movement of the button between a rest position and an unlocking position. - The manual action exerted on the button causes a movement of the safety member from its first position to its second position. - The displacement of the safety member along the longitudinal axis causes a displacement of the button along the radial axis. - The button and the safety member each comprise an oblique surface extending in a plane forming a non-zero angle with a longitudinal plane perpendicular to the radial axis. A normal to the oblique surfaces extends in a plane passing through the longitudinal axis and the radial axis. During the movement of the safety member from its first position to its second position, the oblique surfaces of the button and the safety member slide in surface contact against each other. - The angle is equal to 45 °. - The male part comprises an adapter housed inside the female element and comprising radially movable balls and adapted to maintain a male end of the fitting configured configuration in the adapter, when the locking device is in a first position wherein it holds the adapter at a first fitting depth of the adapter in the female member and in a press fit configuration. - The safety device comprises an additional retaining means, such as a tooth, adapted to maintain the male portion fitted into the female element when the locking device is maintained in its second position. - The locking device comprises a first part and a second part housed inside the first part. - The locking device comprises an additional retaining means adapted to retain the male part in the female element at a second fitting depth in a closed configuration of the fluid passage between the pipes. During an intermediate connection step, the male part pushes the safety member towards its second position. - A sealed and flexible envelope is disposed on the female element, and covers the button and the locking device, in particular a cover made of an elastic material. The invention will be better understood and other advantages thereof will appear more clearly on reading the following description of four embodiments of a coupling according to the invention, given solely by way of example and with reference to the accompanying drawings in which: - Figure 1 is a partial section of a male element and a female element of a coupling according to the invention, in disconnected configuration, extending along a longitudinal axis represented in broken line, the male element being aligned on the longitudinal axis; - Figures 2 and 3 are partial sections of the connection of Figure 1, respectively after a first and a second connection steps; - Figure 4 is a partial section of the connector of Figure 1 in connected configuration; - Figure 5 is a section along the line YY 'in Figure 4; - Figure 6 is a partial section of the connector of Figure 1 at the end of a first disconnection step; - Figure 7 is a cross section along the line YY 'in Figure 6; - Figures 8 and 9 are partial sections of the connection of Figure 1, respectively after a second and third disconnection steps; FIG. 10 is an exploded perspective view of a safety device fitted to the female element of the connector of FIG. 1; FIG. 11 is an exploded perspective view, from another angle, of the safety device of FIG. 10; - Figures 12 to 14 are longitudinal partial sections of connectors according to a second, third and fourth embodiments of the invention.
    [0004] The connection shown in FIGS. 1 to 11 is of the single-pulse type, or one-way type with anti-whiplash device, and comprises a female element A and a complementary male part, which is constituted by a male element or end-piece B in this embodiment. The elements A and B are designed to slide into each other in the direction of an axis X-X ', which is a longitudinal axis common to the elements A and B. The elements A and B are connected respectively to an upstream pipe C1 and a downstream pipe C2. The upstream pipe C1 is, itself, connected to a source of fluid under pressure not shown, for example a source of air under pressure, the pipe C2 being itself connected, for example to a pneumatic member of a vehicle earthly. The connection is intended for fluids whose pressure varies between 2 and 300 bars. In a variant, the fluid flows from the pipe C2 to the pipe C1, the upstream and downstream terms being then reversed.
    [0005] Within the meaning of the invention, a proximal portion of one of the elements A and B is a portion facing or close to the pipe C1 or C2, connected to this element A or B, while a distal portion is a part turned towards or close to the other element when these elements are facing each other, ready to be fitted. A body 1 of the female element A is of generally cylindrical external shape with a circular base, centered on the axis XX 'which is also the longitudinal axis of a conduit 12 internal to the body 1, in which a valve 2 is disposed. mobile along the axis X-X '. The valve 2 is subjected to the action of resilient means such as a return spring 3A which exerts a force F3A tending to press protuberances 23 of a head 21 of the valve 2, provided with an O-ring 22, against a support ring 4 mounted inside the body 1 and immobilized by a connecting element 11 screwed into the body 1, on the side of the upstream pipe C1. An O-ring 41 is interposed radially, that is to say in a direction perpendicular and secant to the axis X-X ', between the support ring 4 and the connecting element 11. A ring 5 provided with an annular flange is interposed along the axis XX 'between the body 1 of the female element A and the support ring 4. An O-ring 51 is disposed in a groove delimited on either side by the ring of support 4 and the ring 5. The body 1 is provided with a blind housing 13 extending generally in the direction of an axis YY 'perpendicular and secant to the axis X-X', that is to say radial to the body 1. Inside the housing 13 is slidably mounted along the axis Y-Y ', a locking device consisting of a latch 6 on which elastic means, such as a spring 3B compression, exert an elastic force F3B directed radially opposite a bottom 131 of the housing 13, that is to say towards an outlet 132 of the housing 13. The latch 6, better visible in Figures 10 and 11, comprises a through opening 61 centered on an axis A61 parallel to the longitudinal axis XX 'and adapted to receive a body 101 of the male element B. radial opening 6 of the bolt 6 opens, along the Y-Y 'axis, at an upper end of the latch 6 located on the side of the outlet 132 of the blind housing 13 of the body 1. Opposite the outlet 132 the opening 62 is delimited by a lower end of the latch 6 formed by a bottom wall 65. The bottom wall 65 is located along a central axis A62 of the opening 62 coinciding with the axis Y- Y ', opposite the opening of the opening 62, in other words, the bottom side 131 of the blind housing 13. Along the axis A62, the opening 62 also opens into the through opening 61.
    [0006] Two coaxial holes 63 extending along an axis A9 generally parallel to the axis XX 'are formed in the latch 6 and receive the ends of a shaft 9 housed inside the latch 6. The bottom wall 65 of the lock 6 is equipped with first retaining means formed by a relief 64 of generally annular shape and centered on the axis A61. The relief 64 has a frustoconical surface 642 whose diameter increases along the axis XX 'in a direction from the distal end to the proximal end of the female element A. The frustoconical surface 642 is extended on the side of the proximal end of the female element A by a cylindrical surface 644 whose diameter is smaller than that of the through opening 61.
    [0007] In the absence of external action on the female element A, the spring 3B pushes the bottom wall 65 of the lock 6 against the collar ring 5 which is partially housed inside the through opening 61. 8 is slidably mounted on the shaft 9, in the through opening 61, along the axis A9. The safety member 8 has a hole 81 inside which the shaft 9 extends. The shape of the safety member 8 is inscribed inside a cylindrical envelope with a circular base centered on a A8 axis, and has two flats 8A and 8B parallel to the axes XX 'and Y-Y'. The axis A8 is coaxial with the Y-Y 'and A62 axes. Each flat 8A and 8B is of generally triangular shape, a diagonal of this triangle being adjacent to an oblique surface 82. The oblique surfaces 82 are coplanar and, in the assembled configuration of the female element A, they extend in a plane which forms a non-zero angle α with a longitudinal plane P1 which passes through the axis XX 'and which is perpendicular to the axis YY'. The diameter of the cylindrical envelope in which the safety member 8 fits is strictly smaller than the diameter of the opening 62 of the lock 6, so that the safety member 8 is movable in translation parallel to the axis XX 'and along the shaft 9, relative to the latch 6. The safety member 8 has a proximal inclined surface 84 facing the axis X-X'. Elastic means such as a compression spring 3C are mounted around the shaft 9 and bear against an inner wall of the latch 6 defining the opening 62 and against the safety member 8. The spring 3C pushes back by default. safety member 8 against the inner wall of the lock 6, in the direction of the mouth 14 of the female element A, that is to say in the direction of the distal end of the female element A. A button 7 is mounted on the safety member 8 and extends partially inside the opening 62. Thus, the button 7 is partially housed in the lock 6 and emerges outside the lock 6 when the connection is in a fitted configuration of fluid passage. The knob 7 is generally cylindrical in shape with a circular base, and extends along an axis A7 aligned with the axis A62 of the lock 6 and with the axis YY '. The button 7 is adapted to be actuated manually towards the interior of the body 1, from outside this body. The diameter of the cylindrical envelope of the button 7 is substantially equal to the diameter of the opening 62 of the lock 6, so that the button 7 is slidably mounted in the through opening 61 of the lock 6, along the axis YY '.
    [0008] A slot 71 is formed in the button 7 parallel to the axis A9 and receives the safety member 8 which is blocked on either side of the slot 71 by side walls 7A and 7B of the button 7. The side walls 7A and 7B each comprise an oblique surface 72 extending in a plane which forms a non-zero angle α with the longitudinal plane P1. The angle a is equal to the angle delimited between the oblique surfaces 82 of the safety member 8 and the longitudinal plane P1. In the assembled configuration of the female element A, the oblique surfaces 72 of the button 7 come into contact with the oblique surfaces 82 of the safety member 8. A sealed envelope such as a hood or protective sleeve 10 made from a flexible and elastic material, for example a rubbery material such as an elastomer, is disposed on the body 1 of the female element A, on the side of the mouth 14, and covers the latch 6 and the button 7 so as to protect them from external pollution. Thus the button 7 is protected while remaining maneuverable. The protective cover 10 has an opening 10A opening into the conduit 12 of the body 1, for the introduction of the male element B. An annular bead 10B of the cover 10 is disposed in a corresponding groove of the body 1, for the maintenance of position of the cover 10 on the body 1. When the female element A is used with the button 7 facing upward, as shown in Figure 1, the button 7 is retained in the latch 6 by gravity. When the button 7 is pointing downwards, the button 7 tends to separate from the body 1 of the female element A. The sleeve 10 envelops the outer part of the lock 6 and the button 7, so as to prevent the button 7 from separating from the body 1 of the female element A. The button 7, the safety member 8, the shaft 9 and the spring 3C constitute a safety device adapted to lock the latch 6 in the locked position. The body 101 of the male element B has a groove 105 of annular shape, delimited on one side by a distal annular flange 102, and on the other side by a first frustoconical surface 106 proximal whose diameter decreases in a direction ranging from the proximal end to the distal end of the male element B. Along the axis XX 'and opposite the groove 105, the frustoconical surface 106 is extended by a cylindrical surface 108 whose diameter is greater than that of the back of the throat 105.
    [0009] The flange 102 has a cylindrical outer surface 104 whose diameter is greater than that of the bottom of the groove 105, so that a shoulder 107 perpendicular to the axis XX 'adjoins the distal end of the groove 105. 8 has a proximal end 83 facing towards the pipe Cl and able to come into contact with the shoulder 107.
    [0010] The cylindrical surface 104 is extended, opposite the groove 105, by a frustoconical surface 103 whose diameter decreases in a direction from the proximal end to the distal end of the male element B. FIG. the male element B and the female element A in disconnected configuration. In this configuration, the spring 3A pushes the valve 2 towards the mouth 14 of the female element A, in a first position, or closed position, so that the inner conduit 12 of the female element A is obstructed by the valve 2, the O-ring 22 being pressed radially against the ring 4. The spring 3B pushes the latch 6 opposite the bottom 131 of the blind housing 13, in a first position, or out position, in which the latch 6 comes abutting against the collar ring 5 and protrudes from the body 1 by a first height HI.
    [0011] The spring 3C pushes the safety member 8 towards the mouth 14 of the female member A, against the latch 6 in a first position, or distal position. In this position, the axis A8 of the safety member 8 is offset on the side of the mouth 14 of the female member A with respect to the Y-Y 'and A62 and A7 axes.
    [0012] The button 7 is held in a high position, or rest position, relative to the body 1 of the female element A because the oblique surfaces 72 of the button 7 rest against the oblique surfaces 82 of the safety member 8. The FIG. 2 shows the connection at the end of a first connection step, in which the male element B is introduced into the mouth 14 of the female element A until it abuts against the valve 2 and begins to push the latter against the restoring force F3A of the spring 3A. The first frustoconical surface 103 of the male element B comes into contact with the frustoconical surface 642 of the relief 64 of the lock 6. During the first connection step, the male element B does not interact with the safety member 8, which remains in abutment against the lock 6, the side of the mouth 14 in its distal position. In other words, the safety member 8 does not rest on the male element B. FIG. 3 shows the connection at the end of a second connection step, in which the male element B has continued to progress in the female element A, further pushing the valve 2 out of its seat, in an open position, or second position, so as to allow the passage of fluid between the male B and female A elements. The male element B being surrounded by the collar ring 5, it remains centered on the longitudinal axis X-X '. During the second connection step, the flange 102 of the male element B slides against the relief 64 of the lock 6, until the cylindrical surface 104 of the collar 102 comes into contact with the cylindrical surface 644 of the lock 6, which has the effect of pushing the latch 6 to the bottom 131 of the blind housing 13, opposite the restoring force exerted by the spring 3B, so as to allow the fitting of the male element B.
    [0013] During the second connection step, the second frustoconical surface 106 of the male element B pushes the safety member 8 towards its proximal position, or second position, opposite the mouth 14 of the female element A, against the restoring force F3C exerted by the spring 3C. The co-operation of the oblique surfaces 72 and 82 constitutes an angle gear which causes the button 7, kept in contact with the safety member 8 by the cover 10, to move towards the bottom 131 of the blind housing 13, along the radial axis Y-Y ', without the user activating it. The oblique surfaces 72 and 82 slide in surface contact with each other during this movement. A normal to the oblique surfaces 72 and 82 extends in a plane passing through the X-X 'and Y-Y' axes.
    [0014] Thus, the movement of the safety member 8 along the axis XX 'and in a direction from the distal end to the proximal end of the female member A causes a radial movement of the button 7 towards the inside the body 1 of the female element 1, along the axis Y-Y ', in a lowered position or unlocking position. At the end of the second connection step, the latch 6 is in a retracted position or intermediate holding in which it exceeds the body 1 of a second height H2 less than the first height H1. In the connected configuration of the fitting, or fitted configuration of fluid passage, shown in FIGS. 4 and 5, the flange 102 of the male element B has protruded from the relief 64 which is housed in the groove 105 of the male element B , in contact with the shoulder 107. Thus, the spring 3B can push the latch 6 in the extended position. Along the X-X 'axis, the male member B has reached a first fitting depth in which the connector is in the press fit configuration and wherein the latch 6 is in its first position. The fitting depth is measured between the distal end of the female element A and the distal end of the male element B. The lock 6 drives with it towards the outside of the body 1 the safety member 8 which is no longer locked in translation by the second frustoconical surface 106 of the male element B, so that the spring 3C pushes the safety member 8 against the latch 6 in its distal position, in contact with the cylindrical surface 108.
    [0015] The movement of the safety member 8 causes a displacement of the button 7 along the Y-Y 'axis and opposite the bottom 131 of the blind housing 13, so that the button 7 is in the upper position. Thus, the movement of the safety member 8 along the axis XX 'and in a direction from the proximal end to the distal end of the female member A causes a radial movement of the button 7 towards the outside the body 1 of the female element 1. In the connected configuration, the valve 2 is pushed by the male element B out of its seat, in the open position, against the restoring force F3A of the spring 3A, so as to allow the passage of the fluid between the female element A and the male element B.
    [0016] The latch 6 holds axially the male element B in the female element A through the cooperation between the relief 64 and the shoulder 107 of the flange 102. The latch 6 is in the extended position and protrudes from the body 1 of a third height H3 greater than the second height H2 and equal to the first height H1.
    [0017] The safety member 8 is in radial abutment against the cylindrical surface 108 of the male element, on an area diametrically opposed to the relief 64. In other words, the normal to the contact extends in a radial direction. The safety member 8 thus holds the male element B against the relief 64 of the lock 6, which is diametrically opposed to the bearing zone between the safety member 8 and the male element B, so that when the connection is subject to vibrations, movements of the moving parts of the fitting do not cause an inadvertent disconnection. Thus, the safety member 8 holds the latch 6 in its extended position when the male element B is fitted into the female element A. In a variant, the construction sets allow the safety member 8 to be located in a position diametrically opposed to this support zone, without there being an effective contact between the safety member 8 and the male element B. However, the safety member 8 is then able to bear radially against the male element B. Figures 6 and 7 show the connection at the end of a first disconnection step, in which a user exerts a force F of movement of the button 7 towards the bottom 131 of the housing 13, this effort being directed along the radial axis YY 'and moving the knob 7 to its lowered position. The button 7 emerges outside the latch 6 in its high position when the fitting is in a fitted configuration, so that the force F exerted by the user is located on the button 7, the latch 6 not being actuated. directly by the user.
    [0018] The safety member 8 then slides along the shaft 9 opposite the mouth 14 of the female element A, thanks to the cooperation between the oblique surfaces 72 and 82 which provides a return angle. The button 7 thus pushes the safety member 8 in its proximal position, against the restoring force F3C exerted by the spring 3C.
    [0019] During the first disconnection step, the safety member 8 slides against the second frustoconical surface 106 of the male element B and bears against the bottom of the groove 105 until the proximal end 83 abuts against the shoulder 107. The proximal portion 83 of the safety member 8 abutting the shoulder 107 constitutes an additional retaining means adapted to retain the male member B fitted into the female element A when the latch 6 is in position. its low position.
    [0020] This additional retaining means is distinct from the first retaining means 64 of the bolt 6 and the second retaining means 102 of the male element B. The depressing of the button 7 causes the bolt 6 to move along the radial axis YY towards the bottom 131 of the blind housing 13, against the restoring force F3B exerted by the spring 3B. The action F, for example manual, along the radial axis YY 'on the safety device, of which the button 7 is part, therefore causes the depression of the button 7, that is to say its movement between its position. high and low position. First, the depression of the button 7 causes a radial sliding of the safety member 8 to the bottom 131 of the housing 13. Then, in the same disconnection sequence, the depression of the button 7 causes the lowering of the lock 6 the along the radial axis YY 'At the end of the first disconnection step, the lock 6 is in abutment against the bottom 131 of the blind housing 13, in a low position, or second position, so that the relief 64 is located out of the groove 105 and no longer cooperates with the flange 102 of the male element B, so as to allow the male element B to be released from the first fitting depth. The safety member 8 makes it possible to hold the male element B and the female element A as long as the latch 6 is held in its second position by the user's force F on the safety device. In a second disconnection step whose end is shown in FIG. 8, the user releases the force F exerted on the button 7, and the spring 3A pushes the valve 2 towards its seat, the valve 2 being then in an intermediate position. The valve 2 pushes the male element B out of the female element A, and the flange 102 of the male element B simultaneously pushes the safety member 8 into its distal position, aided by the restoring force F3C of the spring 3C The release of the force F exerted on the button 7 is accompanied by the sliding of the male element B out of the female element A, with a gradual and controlled sliding between the cylindrical surface 104 of the male element B against the inclined surface 84 of the safety member 8. The translational movement of the safety member 8 is accompanied by a radial movement of the button 7 to its upper position, thanks to the cooperation of the oblique surfaces 72 and 82. The connection is then in a purge position in which the pressure drops, the male element B being retained in the female element A by the safety member 8. This intermediate position allows the disconnection of the male element B and the female element Has no whiplash effect. In other words, the male element B is not ejected violently out of the female element A. In a third disconnection step shown in Figure 9, the spring 3B pushes the latch 6 away from the bottom 131 of the blind housing 13, the frustoconical surfaces 103 and 642 of the male element B and the latch 6 then being in contact. The lock 6 drives the safety member 8 along the radial axis YY 'and outwards. The safety member 8 disengages from the groove 105 and stops cooperating with the male element B, so as to allow the retraction of the male element B out of the female element A, until the spring 3A has pushed the valve 2 and the male element B into the disconnected configuration of the fitting. Figure 12 shows a mono-pulse type connection according to a second embodiment of the invention. In the following, the elements of the connector of FIG. 12 similar to those of the connector of FIGS. 1 to 11 bear the same numerical references, increased by 1000. In the following, the analogous elements of the second embodiment are not described in detail. . The connection of FIG. 12 comprises a male element 1101 and a female element A equipped with a ball adapter B housed inside a body 1001 of the female element A and having the same function as the intermediate part described. in the patent application EP 1 422 462.
    [0021] At its distal end, this adapter B has female means B1 for receiving and connecting the male element 1101, while it defines a male end B2 at its other end. It is therefore a connecting element both male and female. The female element A is equipped with a bipartite lock 1006, slidably mounted in the body 1001 of the female element A along a radial axis Y-Y '. The latch 1006 consists of a first portion or outer portion 1006A and a second portion or internal portion 1006B which is received in a hollow housing 1061A of the outer portion 1006A opening both towards a bottom 1131 of a blind housing 1013 of the body of the female element A, and towards a mouth 1014 of the body 1001 by which can be introduced a body 1101 of the male element B. The outer portion 1006A also defines a generally circular opening 1062A which adjoins the dwelling. A bottom wall 1065 of the inner part 1006B is equipped with a first retaining means formed by a relief 1064. The safety member 1008 is provided with retaining means such as a tooth 1082 which protrudes towards the body. B adapter. Thus, the safety device, more precisely the safety member 1008, comprises additional retaining means formed by the tooth 1082 and able to hold the adapter B fitted into the female element A when the lock 1006. is kept in its low position, or second position.
