Application, in particular, to electrical cabinets.

Description

i "Cabinet with locking device The present invention relates to

in a general way

  cabinets with two or more doors.

  For some applications, at least, it turns out that it is desirable that an order be established between the doors

preferential opening.

  This is the case, in particular, for certain electrical cabinets, that is to say for cabinets implemented

  for housing and protecting electrical equipment.

  It is common, in fact, that, in such a case, one of the doors, called below for simple convenience door

  main, controls the power-up of the assembly.

  In other words, this energization is only possible when this main door is closed, and, at

  the opening of it, it is suspended.

  It is therefore interesting, for obvious security reasons, that the opening of the other doors, hereinafter called simply for convenience, secondary doors, cannot

  intervene only after that of the main door.

  It has in fact already been proposed to equip cupboards of this type with a locking device from which it follows that the opening of a secondary door is effectively

  conditioned by that of the main door.

  In practice, this locking device comprises, for the secondary door, or for each of the secondary doors, a lock, which, under the control of a command controlled by the main door, is movably mounted on the jamb of such a door. secondary between an authorization position and a locking position, and a keeper, which is carried by the secondary door, and with which this lock engages when it is in the locking position. More precisely, in the corresponding already known embodiment, the control controlled by the main door comprises, on the one hand, a pusher, in the form of a fork, carried by this main door, and, on the other hand, a rod, which runs rigidly over the entire length of the doors in question, and which, mounted movable along its length, is actuated by the push-button of the main door when it is closed and carries, to the right of the lock of each secondary door, a clean cam when this lock is actuated. As a corollary, this lock is simply mounted pivoting by gravity between its authorization position and its

condemnation position.

  Such an embodiment has various drawbacks.

  First of all, carried out, in practice, from door to door, by rod sections placed end to end whose length must be adjusted to the width of the corresponding door, the rod used is difficult to

mount and adjust.

  Furthermore, it does not lend itself to any

change of direction.

  Finally, and most importantly, there is nothing to prevent the main door from being closed even before the secondary doors

are.

  It is therefore possible, under these conditions, that, to the detriment of safety, malfunctions will occur, leading inadvertently to re-energizing the assembly before even one or the other of the doors.

be closed.

  The present invention generally has for

  object an embodiment to avoid these drawbacks.

  More specifically, it relates to a cabinet of the kind comprising at least two doors, one said here for simple convenience main door, the other said here for simple convenience secondary door, and a locking device which results in that the opening of the secondary door is conditioned by that of the main door, this locking device comprising, for the secondary door, a lock, which, under the control of a command controlled by the main door, is movably mounted on the jamb of this secondary door between an authorization position and a locking position, and a keeper, which is carried by the secondary door, and with which the lock engages when it is in the locking position, this cabinet being d '' generally characterized in that the control of the locking device comprises at least one sensor, which, movably mounted on the frame of the main door, is subjected to hubs ns elastic which permanently urge it towards a deployed position for which it interferes with the path of this main door, and a cable, which, coupled to this probe, is suitable for actuating the lock of the

secondary door.

  In such an embodiment, the cable can advantageously run continuously all along the doors concerned. Advantageously, this results in great ease of

  mounting, and minimization of necessary adjustments.

  In addition, the cable used according to the invention can easily, if necessary, pass, along its course, over at least one deflection member, which advantageously makes it possible to print on this cable any change in direction which may s 'prove desirable, especially for the control of a secondary door arranged transversely to the main door. Preferably, the cable used according to the invention splits the lock of the secondary door on the probe of the main door, and the latter is mounted movably in

  translation on the frame of the latter.

  Thus, the lock of the secondary door is positively controlled by the probe of the main door, and, likewise, it can advantageously control positively.

this feeler.

  According to a development of the invention, advantage is taken of this possibility to ensure that the main door cannot be closed before all the doors

secondary are.

  According to this development, the lock of a secondary door is also mounted mobile in rotation about an axis parallel to its direction of translation, between a release position and a blocking position, according to, respectively, the closed position and the open position of the secondary door, and there is provided, on the jamb of this secondary door, a fixed stop which, disposed between the latch and the probe of the main door, interferes with the path of translation of this latch when

  it is in the locked position.

  Thus, if, when the main door is closed, any of the secondary doors is not itself closed, the lock of this secondary door is in the locked position and, by the cable which hitched it to the probe of the main door, it opposes any withdrawal of this probe, then in the deployed position, so that, coming to interfere with it, the main door is

  effectively prevented from being closed.

  The characteristics and advantages of the invention

  will emerge from the description which follows,

  by way of example, with reference to the accompanying diagrammatic drawings in which: FIG. 1 is a perspective view of a cabinet according to the invention; Figure 2 is schematically, along the line II-II of Figure 1, a sectional plan view showing, as a whole, the locking device which the team, for the closed position of the door main and secondary doors of this cabinet; Figure 3 is a partial sectional view which, on a larger scale, the detail of Figure 2 identified by an insert III in this Figure 2, and corresponding to the broken line III-III of Figure 5, is relates to the probes associated with the main door of this cabinet, for the closed position of this main door; Figure 4 is a front elevational view of these feelers, along the broken line IV-IV of Figure 5; Figure 5 is a partial cross-sectional view of the cabinet according to the invention in the vicinity of these feelers, along the line V-V of Figure 4; Figure 6 is a perspective view of these sensors, seen from above; Figure 7 is a perspective view of one of them, seen from below, with an exploded view, the screw ensuring its pivoting; Figure 8 is a partial sectional view which, taking on a larger scale, the detail of Figure 2 identified by an insert VIII in this Figure 2, and corresponding to the broken line VIII-VIII of Figure 10, relates to the lock of a secondary door; Figure 9 is a front elevational view of this lock, along the broken line IX-IX of Figure 10; Figure 10 is a partial cross-sectional view of the cabinet according to the invention in the vicinity of this lock, along the line X-X of Figure 9; Figure 11 is a perspective view of this lock, with its support; Figure 12 is a perspective view of the keeper with which this lock is associated; Figure 13 is another perspective view of this lock, seen in isolation and from above; Figures 14, 15 and 16 are views which each correspond respectively to those of Figures 3, 4 and 5, for an open position of the main door; Figures 17 and 18 themselves each correspond respectively to those of Figures 8 and 9, for the same opening position of the main door; Figure 19 is a partial cross-sectional view which, similar to that of Figure 10, corresponds to an open position of the secondary door shown. In general, and as illustrated in these figures, a cabinet 10 according to the invention comprises at least two doors 11A, 11B, 11'B, namely, a main door 11A

  and at least one secondary door 11B, 11'B.

  In the embodiment shown, the cabinet 10 comprises, however, by way of example, four doors, namely, the main door 11A, two secondary doors 11B acting in the same plane as the main door 11A, and a door secondary 11 'B involved in a plan

perpendicular to the previous one.

  Furthermore, in this embodiment, all of these

  doors 11A, 11B, ll'B have the same height and the same width.

  In the embodiment shown, the cabinet 10 results from the juxtaposition, side by side, of three modules M, namely, a middle module, which comprises the main door 11A, and two lateral modules, one of which comprises one secondary doors 11B while the other has the other secondary door 11B on the front, and, laterally, the door

secondary 11'B.

  These modules M each have an internal framework, which forms, for the corresponding door 11A, 11B, ll'B, a frame 12A, 12B, 12'B comprising, in the usual way, two

  uprights 13 and two crosspieces 14, one high, the other low.

  These uprights 13 and these crosspieces 14 are sections

of the same type of profile.

  For example, these are profile sections of the type described in the French patent which, filed on September 18, 1991 under No. 91 11481, was published under

No 2,681,402.

  The assembly is completed by covering panels 15, either upper, lateral or rear, and rests, the

  more often, on a base, not visible in the figures.

  The foregoing provisions are well known in themselves, and, not falling within the scope of this

  invention, they will not be described in more detail here.

  In a manner also known per se, the doors 11A, 11b, 11'B are articulated by hinges 16 to one of the uprights 13 of their jambs 12A, 12B, 12'B, in one direction

  which, in practice, is indifferent.

  For example, and as shown, the opening is made on the left for the main door 11A and for one of the secondary doors 11B, while it is done on the right for

  the other secondary door 11B and for the secondary door ll'B.

  In practice, in the embodiment shown, and as is better visible for the main door 11A in Figures 5 and 16 and for a secondary door 11B in Figures 10 and 19, the doors 11A, llB, 11 ' B are each formed by a front panel 18 on the internal face of which are reported, on the one hand, along a first rectangular contour, a seal 20, for contact with the frame 12A, 12B, 12'B corresponding, and, on the other hand, along a second internal rectangular contour to the previous one, a frame 21, for the stiffening of the front panel 18, as well as, optionally, for the support or the guiding of

  various components not shown.

  The doors 11A, 11B, ll'B are each each individually equipped with a closing device, not visible in the figures, and this is under the control of a handle 22, which, of course, intervenes, in practical, on the side

opposite their hinges 16.

  In a manner known per se, finally, the cabinet 10 according to the invention comprises a locking device 24 which results in the opening of at least one of the secondary doors 11B, 11'B, and, in practice that of all of these, is conditioned by the opening of the door

main 11A.

  More specifically, this locking device 24 comprises, for each of the secondary doors 11B, 11'B, a latch 25, which, under the control of a command 26 controlled by the main door 11A, and, therefore, centralized, is mounted movable on the frame 12B, 12'B of the secondary door 11B, 11'B between an authorization position and a locking position, and a keeper 27, which is carried by this secondary door 11B, 11'B, and with which the lock 25 comes in

  taken when it is in the locked position.

  According to the invention, the control 26 comprises at least one feeler 28 which, movably mounted on the frame 12A of the main door liA, is subjected to elastic means 29 which permanently urge it in the direction of a deployed position for which, as shown in Figure 14, and as will appear below, it interferes with the path of this main door 11A, and, more precisely, on that of its frame 21, and a cable 30, which, coupled to this probe 28 is suitable for actuating the lock 25 of the secondary door 11B, 11'B concerned. Preferably, and this is the case in the embodiment shown, the cable 30 splints to the probe 28 of the main door 11A the lock 25 of the secondary door

11B, 11'B concerned.

  In the embodiment shown, for controlling at least one secondary door 11B, 11'B on either side of the main door 11A, the control 26 of the locking device 24 according to the invention comprises, so symmetrical, on the frame 12A of the main door 11A, two feelers 28, to each of which is attached a cable 30, and to each of which are associated means

elastic 29.

  In practice, in the embodiment shown, and having regard to the relative position of the doors 11A, 11B, 11'B, one of the probes 28, and the corresponding cable 30, are assigned to the control of one of the doors secondary 11B, while the other of these probes 28, and the corresponding cable 30, are assigned to the control of the other of these

  secondary doors 11B and that of the secondary door 11'B.

  At its end opposite to the probe 28 with which it is associated, each of the cables 30 is coupled to a spring 33, in practice a simple tension spring of the coil spring type, which is coupled, at its other end, to a fixed point, for example at an amount 13, and which constitutes the means

  elastic 29 to which this probe 28 is subjected.

  Intervening between this probe 28 and the spring 33, the lock 25 associated with a secondary door 11B, 11'B is secured to the cable 30 in passing, by simply pinching this

  cable 30 by a screw 34, Figures 8 and 10.

  Because of their flexibility, the cables 30 can advantageously be the object of at least one change of direction, having been passed to do this on at least one member.

of reference.

  In the embodiment shown, this is the case for serving the secondary door 11′B, for which the cable 30 concerned is, on its route, passed over a deflection member 35, formed for example by a simple bend fixed, which, acting in the corner area of the cabinet 10 between this secondary door 11'B and the secondary door 11B to which it follows, is, for example, integral with the corresponding amount 13. For the rest, the cables 30 extend in a rectilinear manner in the embodiment shown, running in practice along the top cross member 14 of the frame 12A,

  12B, 12'B of doors 11A, 11B, ll'B.

  In what follows, and for simplicity, only a probe 28 and a

lock 25.

  In practice, this is the probe 28 and the latch 25 controlling the secondary door 11B which, in FIG. 1, is

  located to the left of the main door 11A.

  In the embodiment shown, the probe 28 is pivotally mounted on the frame 12A of the main door 11A, and, more precisely, on the top cross member 14

of this frame 12A.

  It forms, in practice, Figures 3, 6 and 7, a lever, which is articulated in its central region 36, and which has, on either side thereof, two arms 38, 39, one on which acts the main door 11A, the other to which the

cable 30.

  In practice, also, the probe 28 is engaged with a guide 40, by means of which it is attached to the frame 12A of the main door 11A, and, more precisely, on the lower surface of the upper cross member 14

of this frame 12A.

  This guide 40 has, at right angles, two wings 41, 42, one by which it is applied to the lower surface of the top cross member 14, the other which forms an edge which has fallen

compared to the previous one.

  At the ends of the edge formed between these two wings 41, 42, the guide 40 has, along this edge, for the passage, and the guidance, of the two feelers 28, two

notches 43.

  The central zone 36 of a feeler 28, which is flat, is applied to the wing 41 of the guide 40, on the side of the lower surface of the latter, and, for the pivoting of this feeler 28, it has a hole 45 with which is engaged, by a smooth surface 46, a screw 47 which, also passing through the wing 41 of the guide 40, by means of a bore 48 of the latter,

  fixes the assembly to the top cross member 14 of the frame 12A.

  The arm 38 of a probe 28 has, at an angle, in the embodiment shown, two sections 49, 50, one which is in continuity with the central zone 36, and the other which, beyond the wing 42 of guide 40, forms a fallen edge with respect to the previous one, so that contact with the door

  main 11A takes place over a sufficient area.

  In practice, and as can be seen in FIG. 5, this contact is made by the frame 21 carried by the panel

  facade 18 of this main door 11A.

  The other arm 39 of a probe 28 extends continuously with the central zone 36, and, for the coupling of the corresponding cable 30, it is simply shaped as a hook, thus

that it is visible in Figure 7.

  In the embodiment shown, the lock 25 controlling a secondary door 11B, 11'B is mounted movable in translation on the frame 12B, 12'B of this secondary door 11B, 11'B, and, more precisely, on the cross member 14

high of this frame 12B, 12'B.

  Its direction of translation D, shown schematically in broken lines in FIG. 11, can be considered to be

  materialized by the cable 30 to which it is coupled.

  Preferably, and this is the case in the embodiment shown, as shown diagrammatically in broken lines in FIG. 11, the latch 25 is also mounted mobile in rotation about an axis A parallel to its direction of translation D, between a release position, shown in Figures 9 to 10, and a locking position, shown in Figures 17 to 19, according to, respectively, the closed position and the open position of the secondary door 11B concerned, and it is provided, on the frame 12B of this secondary door 11B, a fixed stop 52, which, disposed between the latch 25 and the probe 28, interferes with the translation path of this latch 25 when the latter is in position

blocking.

  In practice, the lock 25 is, to do this, mounted movable on two parallel guide axes 54, 55, FIG. 11, one of which, the axis 54, is fixed, and materializes its axis of rotation A, and the other, axis 55, is on the contrary mounted mobile

  transversely to itself in fixed buttonholes 56.

  More specifically, in the embodiment shown, and as it is better visible in Figures 11 and 13, the latch 25 comprises a plate 58, with, along the transverse ends thereof, which are in practice perpendicular to the cable 30, two transverse fallen edges 59, by which it is slidably engaged on its guide pins 54, 55, these transverse fallen edges 59 having

this effect of the holes 60, 61.

  The screw 34 ensuring the pinching of the cable 30 is engaged with this plate 58, which, moreover, and for reasons which will appear below, is largely hollowed out by a

  buttonhole 62 in its middle part.

  For the passage and the guiding of the cable 30, notches 63 are provided at the ends of the edges which

  form with the plate 58 the transverse dropped edges 59.

  Jointly, the guide pins 54, 55 of the latch 25 are carried by a support 64, with which this latch 25 forms a sub-assembly 65, and by means of which it is attached to the frame 12B of the secondary door 11B concerned. . In the embodiment shown, this support 64 has, itself, a plate 66, with, along the transverse ends thereof, two transverse dropped edges 67, which each have, on the one hand, a bore 68 , for the implantation of the guide pin 54, and, on the other hand, the fixed buttonhole 56 allowing the travel

transverse of the guide axis 55.

  In its median zone, the plate 66 has a hole 69, for the passage of a screw 70 ensuring the fixing of the assembly to the frame 12B of the secondary door 11B concerned, and, more precisely, to the crosspiece 14 high of this frame 12B, on the lower surface of this crosspiece 14

  high, as shown in Figure 10.

  Due to the buttonhole 62 presented by the plate

  58 of the lock 25, the screw 70 does not interfere with the latter.

  To block the rotation of the support 64 on the top cross member 14, the plate 66 of this support 64 also has, on either side of the bore 69, two bosses 71, which, in practice, result from a simple drawing , and which, each individually, cooperate in engagement with one of the holes 72 which, moreover, has from place to place the high crosspiece 14, as shown diagrammatically in broken lines on

Figure 8.

  In the embodiment shown, the support 64 by itself forms the fixed stop 52 associated with the lock 25, and, for operation of such a lock 25 in one direction or the other, depending on the probe 28 to which it is coupled , that is to say according to the position of the secondary door 11B concerned with respect to the main door 11A, there is provided, on the frame 12B of this secondary door 11B, and, therefore, in practice, on the support 64 , two fixed stops 52, which each extend respectively on either side of the latch 25. In practice, these fixed stops 52 are formed by the bracket return bracket 74 which have along their free edge the fallen edges transverse 67 of the plate 66 of the support 64, and, as a corollary, the latch 25 is able to cooperate in support with one or the other of these fixed stops 52 by one or the other of its own transverse fallen edges 59. In the embodiment shown, from its free position ration in its blocking position, the bolt 25 is only subjected to gravity, and, from its blocking position to its release position, it is subjected to a cam 75, which is carried by the secondary door 11B concerned , and, more precisely, by the keeper 27 secured thereto, and with

  which cooperates, to do this, its guide axis 55.

  By a plate 76, the keeper 27 is attached to the frame 21 present on the internal surface of the front panel 18 of the secondary door 11B, and, by a tab 77 coming from this plate 76 and provided with a return angle 78 at its end, it is supported on this facade panel 18,

figure 10.

  In practice, for the intervention of a screw 79 suitable for fixing it to the frame 21, the plate 76 of the keeper 27

has a hole 80.

  In the embodiment shown, the keeper 27 forms, transversely to the direction of translation D of the latch 25, at least one spout 81, and the latch 25 comprises, longitudinally, at least one hook 82 by

  which it is able to engage on this spout 81.

  In practice, the keeper 27 forms, transversely, at a distance from each other, two spouts 81, and the latch 25 comprises, in correspondence, two hooks 82, at the rate of one

by spout 81 of the keeper 27.

  The distance L1 separating these two spouts 81 from one another is greater than the width L2 of a hook 82 of the latch 25 measured in the direction of translation D of the latter, FIG. 9, so that these two spouts 81 can pass respectively on either side of such a hook 82 when the latch

is in the authorization position.

  In practice, the hooks 82 of the latch 25 are formed by a longitudinal dropped edge 83 of the plate 58 of this latch, this longitudinal dropped edge 83 having, in its median zone, a notch 84, by which the hooks 82 are

duly individualized.

  In practice, too, the ends of this longitudinal fallen edge 83 are largely at a distance from the transverse fallen edges 59, by providing passages 85 therewith. As a corollary, the spouts 81 of the keeper 27 are formed by flanges 86, which , come in one piece from the plate 76 of this keeper 27, are bent at right angles to this

platinum 76.

  Cam 75 is formed on the edge of these flanges

  86, being divided for half between them.

  It comprises, in practice, on the edge of each of these flanges 86, an engagement section 87, which, oblique with respect to the plate 76, approaching the latter as it approaches of the corresponding spout 81, leads, on the back of this spout 81, at the root thereof, to a depression 88 suitable for supporting the guide pin 55, such that

shown in figure 10.

  It will first be assumed below that the main door 11A is closed, as shown in FIGS. 3 to 5, and that, as a corollary, and as shown for one of them in FIGS. 8 to 10, the secondary doors 11B,

11'B are themselves closed.

  By its frame 21, the main door 11A maintains, under elastic stress, in the retracted position, the feelers

  28, and, by the cables 30, these probes 28 maintain themselves

  same in the locking position each of the latches 25.

  For this locking position, represented in FIGS. 8 to 10, the two hooks 82 of such a latch 25 are each located respectively in line with the two nozzles 81 of the keeper 27 of the secondary door 11B, ll'B concerned, FIG. 9, being in practice engaged with these nozzles 81, by engagement

behind these, figure 10.

  It is thus impossible to open the doors

secondary 11B, 11'B.

  As a corollary, under the action of the cam 75 carried by their keeper 27, the latch 25 which controls them is also in

release position.

  It will now be assumed that, as shown in FIGS. 14 to 16, the main door 11A is open, or,

at least ajar.

  Under the stress of the elastic means 29 associated therewith, and as shown diagrammatically by arrows F1

  in FIG. 16, the feelers 28 pass into the deployed position.

  This results, by the cables 30, and as shown diagrammatically by an arrow F2 for one of them in FIG. 17, a displacement of the latches 25 along their guide axes

54, 55.

  By construction, it is made so that, at the end of this movement, these latches 25 are each in the release position for which their notch 84 and one of their passages 85 are in line with the spouts 81 of the keeper 27 of the secondary door llB, 11'B concerned, as is

  better visible for one of them in figure 18.

  The secondary doors 11B, 11'B can thus in turn be opened, the spouts 81 of their keeper 27 then passing freely through their lock 25 in favor of the notch

  84 and relevant passage 85 thereof.

  As a corollary, for this release position, the latches 25 are, by one of their transverse fallen edges 59, each perpendicular to one of the fixed stops 52 which

are associated.

  When a secondary door 11B, 11'B is open, and as shown diagrammatically by the arrow F3 in FIG. 19, the corresponding lock switches by gravity to the locked position,

  by pivoting about its guide axis 54.

  It can only return to the release position for

  as far as the secondary door 11B, 11'B concerned is closed.

  However, for this blocking position, the latch 25 is directly in line with the fixed stop 52 plumb with which

it was previously.

  If, therefore, the main door 11A is the subject of an attempt to close leading its frame 21 into contact with the feelers 28, as shown diagrammatically by arrows F4 in FIG. 14, these feelers 28 prevent the pursuit of

this attempt.

  Indeed, pressing against the fixed stop 52 close under the stress which it is then the object on the part of the cable, according to arrow F'2 of Figure 17, the latch 25 positively prevents the probe 28 to which it is harnessed from

shift to the retracted position.

  This probe 28 therefore effectively opposes the

  closing the main door 11A.

  Thus, this closure can only occur if all the secondary doors 11B, 11'B are themselves closed. Of course, the present invention is not limited to the embodiment described and shown, but encompasses

any variant of execution.

  For example, instead of coupling the lock of the secondary doors to a feeler of the main door, the cable used according to the invention could carry a clean cam

when this lock is actuated.
