Description

The present invention relates generally to cabinets, or other furniture of this type, of the type comprising a door, the leaf of which is equipped with a closure device suitable for locking it on the frame to which it is articulated.

It relates more precisely to the case where, as described for example in document DE-A-24 57 169, this closure device comprises, on the one hand, at least one rod, which, in the mounting position, is slidably mounted at back of the door leaf, under the control of a cam locked in rotation on a control member available to the user, and which carries at least one bolt transversely, with, associated with this rod, stop means adapted to limit the stroke in at least one direction, and, on the other hand, at least one keeper, which, in the mounting position, equips the door frame, and with which the corresponding bolt of the rod is adapted to cooperate in engagement.

One of the problems to be solved in the production of cupboards, the door of which is thus equipped with such a closing device, is due to the fact that, for a standardization of manufacturing, it is desirable that the leaf of this door is reversible, so that , as required, it can be mounted in one or the other of two mounting directions, one for which it is articulated on the right on the frame, the operating member then being in the left hand for the user, the other for which it is articulated on the left on this frame, the operating member then being on the right hand for this user.

The present invention generally relates to a provision capable of facilitating such a reversal.

More specifically, it firstly relates to a closure device of the type concerned, characterized in that, for the same strike, the rod comprises, staggered at a distance from each other over its height, two bolts separate, one active for a first direction of mounting the door leaf, while the other is moved away from the striker, and conversely, for the direction of assembly of the door leaf opposite to the previous one; it also relates to any cabinet whose door is thus equipped with such a closing device.

Thanks to the fact that, for the same keeper, two bolts are provided on the rod, no intervention is necessary on this rod when the door it equips is turned over.

According to a preferred embodiment, the closure device according to the invention comprises two rods, which, each arranged respectively on either side of the cam, are jointly slidably mounted in opposite directions relative to each other under the control of this, there is associated a keeper with each of the two rods, and the two keepers thus implemented each have two separate inputs, which extend back to back, and one of which is active for one of the bolts of the rods, while the other is active for another of the bolts of the rods for the direction of assembly of the leaf of the door opposite to the previous one.

These strikes can thus advantageously be identical for one and the other of the rods, whatever the direction of mounting of the door leaf.

Their manufacture and installation are advantageously simplified.

Preferably, also, the stop means associated with at least one of the rods implement two pawls which, mounted tilting, are adapted to brace by simple gravity between this rod and a fixed element with respect to it. ci, and one of which is active for a first mounting direction of the door leaf and the other for the opposite mounting direction of the latter.

Thanks to these various provisions, the turning of the door leaf can advantageously be done without any intervention other than that necessary for its execution.

In a manner known per se, and as illustrated in these figures, the door 10 of the cabinet 11 for which the invention is intended, which is for example a cabinet for electrical equipment, comprises, overall, a frame 12 and a leaf 13, which, by hinges, not visible in the figures, is articulated to this frame 12 along one of the vertical edges thereof.

In a manner also known per se, this door 10 is equipped with a closing device 14 comprising, on the one hand, at least one rod 15A, which, slidingly mounted on the back of the leaf 13 under the control of a wedged cam 16 in rotation on a control member 18 available to the user, in this case a handle pivotally mounted about an axis perpendicular to the leaf 13, carries, transversely, at least one bolt 19, and with which are associated, according to the methods described in more detail later, stop means capable of limiting the stroke in at least one direction, and, on the other hand, at least one keeper 20, which equips the frame 12 and with which the corresponding bolt 19 of the rod 15A is adapted to cooperate in engagement.

According to the direction of assembly shown in Figures 1 and 2, the leaf 13 is articulated along the right vertical edge of the frame 12, and the control member 18 is therefore to the left hand for the user.

In practice, the closure device 14 comprises two rods 15A, 15B which, each arranged respectively on either side of the cam 16, are jointly slidably mounted in opposite directions relative to one another under the control of the latter, and, like the rod 15A, the rod 15B carries transversely at least one bolt 19, with, in correspondence, on the frame 12, a keeper 20.

There are thus, staggered in height on this frame 12, for cooperation with the bolts 19 of the rods 15A, 15B, at least two strikes 20.

Of course, there can also be an additional keeper for cooperation with a latch directly controlled by the handle 18.

In the embodiment shown, the rods 15A, 15B consist of metal strips suitably cut and shaped.

They present themselves in song with respect to the leaf 13, and, for their guidance, they are in sliding engagement, on the one hand, jointly, at the height of the handle 18, with a housing 22 in the favor of which the cam intervenes. 16, and, on the other hand, each individually, with at least one guide 23 duly attached to the leaf 13.

The housing 22 belonging to those skilled in the art and not being concerned with the present invention, it will not be described here.

According to the invention, each of the rods 15A, 15B comprises, staggered at a distance from each other over its height, for the same keeper 20, two separate bolts 19, 19 ', one active for a first sense of mounting of the wing 13, while the other is moved away from the keeper 20, and vice versa, for the direction of assembly of the wing 13 opposite to the previous one.

For example, and as shown, the bolt 19 is the one closest to the cam 16 and the bolt 19 'the one which is the furthest from it.

In practice, each of these bolts 19, 19 ′ is formed by two pins 24, which, arranged back to back, each extend respectively on either side of the rod 15A, 15B which carries them, perpendicular to it. this.

They can also be fixed pawns with respect to to the rod 15A, 15B as of pins of which at least part is rotatably mounted relative to the latter.

The strikes 20 are identical for both of the rods 15A, 15B.

They each have two separate entrances 25, 25 ′, which extend back to back, one downwards, the other upwards.

As will appear below, one of these inputs 25, 25 ′ is active for one of the rods 15A, 15B while the other is active for the other of these, and vice versa, at the image of the bolts 19, 19 ′, according to the direction of assembly of the leaf 13.

In the embodiment shown, a keeper 20 is in the form of a relatively massive piece.

The two inlets 25, 25 ′ are each formed respectively by the ends of an elongated recess 26, which, for the passage of a rod 15A, 15B, as shown diagrammatically in broken lines in FIG. 8 for the rod 15A, is formed longitudinally over its entire height in such a keeper 20.

In practice, this keeper 20 generally has a cross section in the general shape of C, with a bottom 27, two flanks 28, and, projecting on these flanks 28, in the median zone at least of these, for retaining the bolts 19, 19 ′, angle returns 29 directed towards one another.

To optionally allow the support of such a bolt 19, 19 ′, and thus counteract any warping of the leaf 13, a stop bar 30 extends transversely from each of the square returns 29 to the bottom 27, in the middle zone flanks 28, projecting from the internal surface of these flanks 28.

To facilitate the engagement of a bolt 19, 19 ′, the ends of the angle returns 29 are cut down by chamfers, both longitudinally, on their internal surface, and transversely, on their edges.

For its attachment to the frame 12, a keeper 20 has, laterally, in the embodiment shown, duly spread over its height, on the one hand, two ears 32, each pierced with a hole 33, and, on the other hand, two wedge-shaped end pieces 34 each arranged respectively at level with the ears 32.

The corresponding provisions not pertaining to the present invention, they will not be described here.

For the sliding of the rods 15A, 15B, the guides 23 have a passage 36, the cross section of which is in the profile of such a rod 15A, 15B, and one of the sides of which is open longitudinally by a slot 37.

In practice, in the embodiment shown, such a guide 23 consists of two parts 38, 38 ′, which are articulated to one another by a hinge zone 39, and between which the passage 36 is divided, the two lips 40, 40 ′ defining the slot 37 presented by the latter each belonging respectively to these two parts 38, 38 ′.

The hinge zone 39, which is constituted by a tongue folded in a U shape on itself, extends generally perpendicular to the rods 15A, 15B.

In correspondence with one another, the two parts 38, 38 ′ are each perforated with a bore 41, 41 ′ suitable for the passage of a screw for fixing the assembly to the leaf 13.

The bore 41 of the part 38 is extended by means of a collar 42 by which this part 38 is fitted into a clearance 42 ′ which the part 38 ′ has at the corresponding outlet of its bore 41 ′.

In practice, it is through this part 38 ′ that a guide 23 is attached to the leaf 13.

Anyway, the guide 23 thus formed can advantageously be made of synthetic material, and, because of its constitution in two parts 38, 38 ′, the mold necessary for its manufacture is advantageously simplified.

Indeed, its molding can thus be done flat, as shown in Figure 12, the corresponding mold is advantageously devoid of any drawer.

In the embodiment shown, the cam 16 is a star cam.

In other words, it is constituted by a pinion, with teeth 44.

Each of the rods 15A, 15B meshes with it by a rack 45A, 45B formed on its edge.

For the rod 15A, this rack 45A extends in favor of a notch 46A, which notches it substantially at mid-width, and whose end edges 47, 47 'are straight.

For the rod 15B, the rack 45B is formed by means of a simple notch 46B, which, if it also affects this rod 15B at mid-width, extends to the corresponding end of the latter, and is therefore open at this end.

The stop means associated with one of the rods 15A, 15B, and it is in practice the rod 15A, implement, in the embodiment shown, two pawls 48, 48 '.

Tilted mounted, these pawls 48, 48 'are adapted to brace by simple gravity between the rod 15A and a fixed element relative to the latter, in this case the housing 22, and one is active for a first direction of assembly of the leaf 13 while the other is active for the opposite direction of assembly thereof.

In practice, these pawls 48, 48 'are pivotally mounted and tiltable, by pins 50, 50', on the housing 22, at the ends thereof, this housing 22 having for this purpose elongated lights 51, 51 ' buttonhole parallel to the rods 15A, 15B, and, arranged generally symmetrically with respect to each other, they each operate respectively at the ends of the notch 46A of the rod 15A.

To do this, the pawls 48, 48 'each have, apart from their pins 50, 50', on the one hand, a spout 52, by which they are adapted to first be able to bear by simple gravity on the rod 15A then coming into engagement with the end edge 47, 47 ′ corresponding to the notch 46A of this rod 15A, and, on the other hand, a shoulder 53, on which protrudes this beak 52, and by which they are also adapted to come to bear by simple gravity on the rod 15A, and therefore to brace to that here, when, by engagement in the notch 46A, this spout 52 is effectively engaged with the end edge 47, 47 ′ corresponding thereto.

The abutment means associated with the other rod 15A, 15B, in this case the rod 15B, result from the simple pressing on it of one of the teeth 44 of the cam 16 away from its rack 45B.

In practice, for support on such a rod 15B, the top part 55 of such a tooth 44 has, on its edge, two flats 56 which each extend respectively on either side of its radial plane of symmetry R.

These flats 56 form an angle A of 90 ° between them.

Taking into account the development thus presented by the top part 55 of a tooth 44, the root 58 of such a tooth 44 narrows in the direction of the axis of the latter, to facilitate its meshing with the racks 45A, 45B.

Preferably, the cam 16 thus has, regularly distributed circularly, eight teeth 44, four of which are in the extension of the diagonals of the square opening 59 which it presents jointly for its setting in rotation on the associated control member 18.

For these four teeth 44, one of which will be that intended to bear against the rod 15B, the flats 56 are each respectively parallel to the sides of this square opening 59.

Thus, no particular orientation is to be observed during the mounting of this cam 16, and therefore no particular indexing is advantageously to be provided on it.

Indeed, all these possible orientations relative to the axis of the control member 18 are then necessarily good.

For the direction of assembly of the leaf 13 shown in FIGS. 1 and 2, it will be assumed, by way of example, that, such that shown, it is the rod 15A which extends over the upper half of this leaf 13 while the rod 15B extends over its lower half.

In reality, a reverse arrangement is just as possible.

It will also be assumed, by way of example, that, as shown, the rod 15A extends on the right side of the housing 22 and the rod 15B on the left side thereof.

But, as before, a reverse arrangement is just as possible.

In the closed position, Figures 1 and 13A, the handle constituting the control member 18 extends downward.

The rod 15A is engaged with the cam 16 by the lower end of its rack 45A, FIG. 14A.

By its beak 52, the pawl 48, which is then the upper pawl, is engaged in the notch 46A of the rod 15A, at a distance from the corresponding end edge 47 of this notch 46A, while carrying, by its shoulder 53 , on this rod 15A.

At the same time, the pawl 48 ′, which is then the lower pawl, hangs freely, by gravity.

Jointly, also, the rod 15B is engaged with the cam 16 by the upper end of its rack 45B.

Consequently, the tooth 44 of the cam 16 immediately downstream of that with which this cam 16 meshes with the rack 45B carries, by a flat 56, on the solid part of this rod 15B, as shown in FIGS. 14A and 15A .

This results in a bracing between the rod 15B and the cam 16, and therefore the blocking in position of the assembly.

Thus, for this closed position, it is the rod 15B which ensures, by the cam 16, the retention of the assembly, its downward stroke by simple gravity being prevented by this cam 16.

For this closed position, the rod 15A is engaged by its bolt 19 with the keeper 20 which is associated with it, by the entry 25 of this keeper 20, while its bolt 19 ′ is at a distance therefrom, as shown diagrammatically on the right part of FIG. 13A.

Jointly, the rod 15B is engaged by its bolt 19 with the keeper 20 which is associated with it, by the entry 25 ′ thereof, while its bolt 19 ′ is at a distance from this keeper 20.

Thus, if, for this closed position, it is the bolt 19, the closest to the cam 16, which is active for one and the other of the rods 15A, 15B, it is, according to reverse arrangements , the input 25 of the keeper 20 concerned which is active for the rod 15A and the input 25 ′ for the rod 15B.

For the opening of the door 10, the handle forming the control member 18 is pivoted by 90 °, as shown diagrammatically by an arrow F1 in FIGS. 1 and 13B, until it extends horizontally.

Due to the meshing due to the cam 16, the rod 15A then moves downwards, as shown by the arrow F2A in FIG. 13B, while the rod 15B moves upwards, as shown by the arrow arrow F2B in this figure 13B.

In practice, the downward movement of the rod 15A, and therefore that upward of the rod 15B, continues until, by its spout 52, the pawl 48 engages with the end edge 47 of the notch 46A of this rod 15A and therefore arches between it and the housing 22.

For the open position, it is the rod 15A which ensures, by the pawl 48, the retention of the assembly.

For this open position, the bolts 19, 19 ′ of the rod 15A both extend away from the corresponding keeper 20, as shown diagrammatically on the right-hand part of FIG. 13B, and it the same is true for the bolts 19, 19 ′ of the rod 15B.

Together, the racks 45A, 45B of the rods 15A, 15B are then substantially at the same height.

To ensure the reversal of the leaf 13 of the door 10, it suffices, this leaf 13 being in the open position, to unhook it, and, after having interchanged with the corresponding hinges the keepers 20, by implanting thence the along the right vertical edge of the frame 12, to return in its 180 ° plane this leaf 13, as shown diagrammatically by an arrow F3 in FIG. 16, and to engage it again on these hinges.

The corresponding open position, shown schematically in Figure 17B, resumes, by symmetry, that shown schematically in Figure 13B.

As previously, therefore, the handle constituting the control member 18 extends horizontally, and the bolts 19, 19 ′ of the rods 15A, 15B both extend away from the corresponding keepers 20 .

But it is now the rod 15B which extends over the upper half of the leaf 13, while the rod 15A extends over its lower half.

Jointly, it is the pawl 48 ′ which then extends to the upper part of the housing 22, while the pawl 48 then extends to the lower part of the latter.

It is then necessary, to ensure disarming of the pawl 48, to pivot slightly upwards, as shown diagrammatically by an arrow F4 in FIG. 17B, the control member 18, until the spout 52 of this pawl 48 escapes from the end edge 47 of the notch 46A of the rod 15A.

Thus released, the pawl 48 therefore hangs freely downwards, by gravity.

Jointly, the pawl 48 ′ carries by its beak 52 on the rod 15A, beyond the end edge 47 ′ corresponding to the notch 46A thereof.

Its arming intervenes systematically by passing the assembly in the closed position.

For this passage into the closed position, it suffices to tilt down the handle constituting the control member 18, as shown diagrammatically by an arrow F′1 in FIGS. 16 and 17A.

The spout 52 of the pawl 48 ′ then engages in fact in the notch 46A of the rod 15A, and it is therefore able to engage with the corresponding end edge 47 ′ thereof in the position of opening.

For this second mounting direction of the leaf 13, it is therefore still the rod 15A which ensures the retention of the assembly for the open position, but by the pawl 48 ′.

On closing, and due to the meshing due to the cam 16, the rod 15A moves upwards, according to the arrow F′2A in FIG. 17B, while the rod 15B moves downwards, according to the arrow F′2B in this figure 17B.

It is then by its bolt 19 ′ that the rod 15A engages with the keeper 20 associated, while its bolt 19 departs from the latter.

But, this keeper 20 having itself been in practice the object of a reversal during its passage from the left vertical edge of the frame 12 to the right vertical edge of the latter, the bolt 19 ′ of the rod 15A enters this keep 20 by the entry 25 ′, then turned downwards, from the latter.

As a corollary, by its bolt 19 ′, the rod 15B is also engaged with the associated keeper 20, by the entry 25, then turned upwards, of the latter, while its bolt 19 remains at a distance from this keeper 20 .

As before, it is the rod 15B which, for this closed position, ensures by the cam 16 the retention of the assembly, by pressing on it a flat 56 of a tooth 44 of this cam 16.

Of course, the present invention is not limited to the embodiment described and shown, but encompasses any variant.

In particular, for the same rod 15A, 15B, several strikes 20 can be provided, and therefore several pairs of bolts 19, 19 ′.

Likewise, several guides 23 can be provided on the height of such a rod 15A, 15B.
