Description

The present invention relates to a locking device in a position

  closed with a sliding leaf in a frame. This device is applicable to all leaves or opening windows or doors, especially in bay windows.

  It allows the locking of the leaf in the frame in a closed position, in which a free amount of the leaf which is perpendicular to the direction of sliding in the frame is supported against a fixed parallel amount of the frame.  Conventionally, to ensure the locking of a sliding leaf in the closed position in a frame, is used a rod which is mounted along the front wall of the amount of leaf located vis-à-vis the amount of dormant, and which is slidable along this wall in a direction perpendicular to the sliding direction of the leaf.  This rod is in particular equipped with 15 hooks, oriented along its longitudinal axis, for its attachment to complementary stops cooperating on the amount of the frame.  A manually operable handle actuates a mechanism for controlling the translation of the bead wire along the amount of the leaf, so as to ensure the attachment of the hooks to the abutments 20 cooperating in the closed position of the leaf.  The latter is thus locked in this position.  The mounting of the rod and hooks on the jamb of the leaf is usually done by the manufacturers of the bay.  The invention aims in particular to provide a device for locking a sliding leaf in a frame that is simple and quick to mount on the leaf, while ensuring good accuracy and good reliability of the lock.  An object of the present invention is thus to reduce the installation time required for the joiner manufacturer of the bay to install the locking device of a sliding leaf in a frame.  A further object of the invention is to limit the number of parts to be handled by the carpenter to do this, in order to simplify assembly operations.  For this purpose, the invention proposes a device for blocking a sliding leaf in a frame, in a closed position in which a jamb of the leaf perpendicular to the sliding direction of the leaf bears against an amount of frame 5 fixed parallel.  The blocking is ensured by locking by means of hooks carried by a rod which is slidably mounted along a front wall of the door jamb, this wall being defined as the wall situated opposite the sleeping pillar against which the leaf must be blocked.  The sliding of the rod along this wall, actuated by a manually operable control mechanism, makes it possible to bring the hooks in correspondence of cooperating abutments arranged opposite the frame post, and their hooking on them. stops so as to achieve locking.  The device according to the invention comprises a rod and at least one hook which is integral with a support piece fixed on a rear longitudinal face of the rod, so that the hook passes through the thickness of the rod and protrudes over a front longitudinal opposite side, being oriented in the axis of this front face.  The rod is mounted on the front wall of the leaf upright by insertion of the support piece into a slot which is provided for this purpose in this front wall, so as to be able to slide along the latter, in the longitudinal direction of the rod, that is to say in a direction perpendicular to the sliding direction of the leaf.  Advantageously, it is thus provided to the carpenter a single piece which is entirely manufactured in the factory and which includes the rod associated with at least one, and preferably two, support pieces of a hook.  This rod is ready 30 to be mounted, very simply for the carpenter, on a section constituting the amount of the leaf to be locked against the frame.  It suffices for the carpenter to machine lights, of oblong shape complementary to the shape of the support pieces but of greater height, in the front wall of the upright, then to arrange the support pieces on the rear face of the rod. in coincidence of these lights and insert them through 2907484 3 them, so as to suspend the rod against the wall of the amount.  The lights having a height greater than the height of the support parts, the latter are able to move slidably through them, in the longitudinal direction of the rod, when the latter is actuated in translation along the amount.  Once the rod mounted on the door jamb, the hooks protrude from the front face, and they are adapted to engage with the corresponding stops arranged in the frame when the rod is actuated in translation to the locking position.  The assembly is thus advantageously easy, simple and precise.  The device according to the invention preferably comprises two support pieces of a hook which are fixed on the bead wire in two parts of opposite longitudinal ends of the latter, so as to ensure better security against burglary.  According to an advantageous characteristic of the invention, the device further comprises a mechanism for controlling the translation of the rod, which is fixed to the rod during manufacture 20 in the factory.  It is thus delivered to the carpenter manufacturer of the bay a single piece ready for use, which comprises both the control mechanism of the rod, the rod, the locking hooks and the means to ensure the sliding assembly of the rod on the leaf jamb.  The control mechanism is conventional in itself.  It is then enough simply to the joiner, after mounting the rod on the amount of leaf, to adapt a handle, conventional in itself, on the control mechanism, to finalize the assembly.  According to preferred embodiments in industrial practice, the invention furthermore fulfills the following characteristics, implemented separately or in each of their technically operative combinations.  In preferred embodiments of the invention, the bead wire is extended at a longitudinal end by a abutment 2907484 4 forming a bolt capable of engaging, in the closed position, in a corresponding hole forming a striker which is located opposite -vis in a beam of the amount, by sliding of the rod towards this spar.  This feature ensures a better security of the locking of the leaf in the closed position, allowing a blocking also against a spar of the frame, arranged parallel to the direction of sliding of the rod.  In preferred embodiments of the invention, the device comprises two rod portions on each of which is fixed at least one support piece of a hook, and which are mounted on a common central control mechanism, in extension the one of the other along the front wall of the sash.  The two rod portions are mounted on this wall in the same manner as in the case described above of a single rod, so that the respective hooks of each are oriented back to back with respect to each other. , and so as to be movable in translation in opposite longitudinal directions along the wall.  This locking mechanism is advantageously bidirectional, that is to say that the respective hooks of the two bead portions come into engagement with the corresponding abutment on the frame each in an opposite direction.  This results in a better strength due to the blockage thus obtained, and a better security against burglary.  In this configuration, the bead portions preferably extend, at their respectively opposite longitudinal ends, each by a stop forming a bolt which is intended to engage, in the closed position of the leaf, in a cooperating hole forming a keeper located in vis-à-vis in a longitudinal member of the frame, by sliding the rod portion towards this spar.  According to an advantageous characteristic of the invention, the support part or parts comprise an abutment stud which prevents the sliding of the bead wire along the door jamb as long as the latter is not in the closed position, ie ie in support 2907484 5 against the corresponding sleeping amount.  This stud protrudes on the longitudinal front face of the rod and is retractable through the latter and through the front wall of the sash amount under the effect of pressure exerted on him.  s This stud is located, in the position where the rod is mounted on the leaf, towards the end of the receiving light of the support piece.  It then blocks the sliding movement of the support piece in the light as long as no pressure is exerted on it.  By cons, when the leaf is in the closed position, io with its amount resting against the amount of the frame, the force exerted on the stud by the amount of frame causes its withdrawal backwards, through the rod and the front wall. of the upright, which releases the sliding movement of the support piece in the light, until the engagement of the hooks with the corresponding stops 15 of the frame.  This feature advantageously makes it possible to achieve an objective of the invention, which is to ensure a good security of the locking of the leaf in the frame, by providing a means for preventing the setting in the locking position of the rod when the leaf is not completely in support against the frame.  In preferred embodiments of the invention, the abutment stud has at its base two lateral shoulders which are slightly protruding from the front face of the support piece.  These shoulders ensure the locking of the stud in the machined lumen 25 in the door jamb, and more particularly in a bulge of corresponding diameter that includes this light for this purpose.  This blocking is ensured as long as the amount of leaf is not in support against the corresponding sleeping amount.  In preferred embodiments of the invention, the device comprises means for adjusting the hook, which are accessible from the front face of the rod and / or from the rear face of the support piece.  These means are in particular means for adjusting the length of the hook protruding from the bead wire.  Control means that can be used in the context of the invention are described in particular in patent document FR 2 823 522.  These means are preferably integrated in the body of the support parts of the device according to the invention, so as to be easily accessible for the carpenter, from the front face of the rod and from the rear face of the support parts, which is located at the inside of the frame formed in section by the profile when the rod is mounted on the leaf jamb.  The device according to the invention therefore advantageously combines a great ease of mounting on the leaf upright, and a wide ability to adapt to all leaf and frame configurations, allowing it to be installed on all doors and / or or windows of standard or specific dimensions.  In preferred embodiments of the invention, the receiving light of the support piece, formed in the wall of the door jamb, has a generally oblong shape complementary to that of the support piece, that is to say having two parts of different widths arranged one above the other along the longitudinal axis of the wall.  This shape allows the workpiece to be inserted through the lumen and then held in that position, avoiding any movement of the workpiece perpendicular to the longitudinal axis of the rod during use.  The lumen may also have, in a longitudinal end portion, a bulge for blocking the abutment stud.  In order to achieve an objective of the invention, which is to facilitate the operations to be performed by the carpenter for mounting, the invention advantageously provides to simplify the shape to give the lights that it must machine on the wall of the amount 30 leaves.  For this purpose, in preferred embodiments of the invention, in the configuration in which the support piece comprises an abutment stud preventing the sliding of the bead wire along the door jamb as long as the latter is not in the 35 closed position against the amount of frame, the abutment stud is integral in retraction of a locking element, which is arranged in the support piece downstream of the stud in the sliding direction of the rod, and so as to be slightly protruding from the front of the support piece.  This locking element is arranged in the light of the door jamb, bearing against a longitudinal end of the latter, when the rod is mounted on the front wall of the door jamb, and as long as it is not in position. support against the corresponding dormant amount.  The locking element thus advantageously ensures the blocking of the abutment stud in the lumen in the opening position of the leaf, by its bearing against the longitudinal end wall of the light in the sliding direction of the rod.  In such a configuration, the locking element advantageously does not create any lateral space around the abutment stud.  The need to provide a bulge on the light of the amount to ensure the blocking of the abutment stud in the light is then removed, which makes the operation of machining the light by the carpenter all the more simple.  Still with the same objective of facilitating the machining operations of the door jamb for the carpenter, in preferred embodiments, the invention advantageously provides that the support piece has a substantially constant width over its entire height and that it comprises retractable lateral tabs slightly inclined towards the outside of the support part with respect to the longitudinal axis of the latter.  These tabs allow the blocking of the support piece in its mounted position on the leaf upright.  It is sufficient for the joiner, to insert the piece through the light of the door jamb, to force it into force by bringing the tabs towards the body of the support piece.  The retractable tabs preferably have beveled slices, so that their retraction against the body of the part is done automatically by the simple movement of driving the piece through the light.  Once the support piece has passed through the lumen, and is disposed inside the leaf post, the lateral tabs return to their original outward projecting position, which automatically ensures the locking of the support piece, which can no longer pass by itself through the light, except to exert on it a specific effort.  These features advantageously make it possible to mount the support piece in a light of the upright which has a simple oblong shape, of constant width over its entire height, and substantially corresponding to the width of the support piece.  Such a light is advantageously easier to machine for the carpenter.  In this configuration, two lateral tabs are preferably arranged on each of the lateral faces of the support piece, so as to be oriented in opposite directions from one another.  Thus, an effective and stable blocking is advantageously provided.  In other preferred embodiments of the invention, the support piece has a wider shape in its lower part than in its upper part, and it is associated with a mounting plate in which is formed a light passage of the 20 support piece complementary shape of that of the latter.  This plate is fixed along the front wall of the door jamb, between the latter and the rod, in coincidence with a slightly smaller form of light than that of the mounting plate, which is provided for this purpose in the wall before the sash amount.  This plate, which is fixed against the wall of the door jamb, has a substantially rectangular shape.  The light formed in the wall of the upright thus has a simple oblong shape, complementary to the outer contour of the locking plate.  This form is quite easy to machine for the carpenter.  The light machined in the mounting plate then ensures the insertion and maintenance of the support part in the leaf jamb, in substitution for this role of the light formed in this amount in the embodiments presented above.  The blocking plate is preferably advantageously constituted so as to allow its self-locking at the level of the corresponding leaf jamb.  According to an advantageous characteristic of the invention, the locking plate comprises at each of its longitudinal ends a retractable tab slightly inclined with respect to the plane of the plate, on the side of the lateral face of the plate intended to abut against the amount of leaf.  These tabs allow the automatic fixing of the plate in the lumen of the front wall of the leaf upright, when the plate is brought to the level of this light, by sliding along the front wall in its longitudinal direction.  This attachment is advantageously provided by elastic support of each of the tabs, which then enter the light against a longitudinal end wall thereof.  Positioning and fixing the plate on the leaf upright are therefore advantageously simple and quick to perform.  This embodiment is particularly suitable in cases where the leaf jamb comprises, on its front wall, a slide for receiving a rod, conventional in itself.  In preferred embodiments of the invention, the support piece has a length of about 50 mm.  This feature advantageously ensures a stable mounting of the rod on the amount of the leaf, by inserting the support part in the machined light in the profile.  The invention also relates to a sliding leaf equipped, on an amount located vis-à-vis a fixed amount of fixed parallel frame, a device as defined above.  The invention will now be more fully described in connection with preferred features and their advantages, with reference to Figs. 1 to 12 in which: Fig. 1 shows a perspective view of a device according to the invention for blocking mono-directional; Figure 2 shows a perspective view of a

perspective view of a device according to another embodiment of the invention and the light of the corresponding leaf post; FIG. 9 shows an exploded perspective view of a device according to another embodiment of the invention; FIG. 10 shows a perspective view of a door jamb intended to receive the device of FIG. 9 and the mounting plate of this device; - Figure 11 illustrates a top view of the blocking plate of the device of Figure 9, mounted on the jamb of Figure 10; And FIG. 12 shows the blocking plate of the device of FIG. 9 mounted on the leaf post of FIG. 11 in sectional view along the plane A-A of this figure.  The device according to the invention is intended to equip a sliding leaf in a frame, so as to ensure its locking in the closed position, in which a free amount of the leaf perpendicular to the sliding direction bears against a fixed amount. parallel of the frame.  In the embodiment shown in FIG. 1, the device according to the invention comprises a rod 1 on which are fixed two support pieces 2 which each carry a hook 3 at the end of a rod 4.  All of these elements is made of a material both light and strong, including a plastic material.  The two support pieces 2 are respectively disposed on two opposite longitudinal end portions of the rod 1.  In the embodiment shown in Figure 1, they have a generally elongated shape, consisting of two parts arranged one above the other along the longitudinal axis of the part 2, a lower part less wide and a wider upper part (the lower and upper parts being defined with respect to the direction of orientation of the support parts 2 in the figure).  They are fixed on a longitudinal rear face 8 of the rod 1, by means of fixing screws 5.  The parts 2 are mounted on the rod 1 so that the hooks 3 pass through the thickness of the rod 1 and protrude on its longitudinal front face 9.  In the central part of the rod 1 is fixed, by means of a screw 7, a mechanism 6 for controlling the translation of the rod along the upright.  This mechanism is conventional in itself, and it is actuated by a handle which is not shown in the figures but which is also conventional in itself.  The device shown in Figure 1 is delivered as a single piece to the carpenter who must install it on the amount of a door leaf or sliding window.  The amount of leaf is conventionally constituted by an extruded section of PVC or aluminum, which has a hollow frame-shaped section.  Figures 2, 3 and 5, this amount is shown without one of its side walls, so as to show the part of the device according to the invention which is disposed within this amount.  On its front wall 11 intended to bear against the amount of frame, the section 10 must be machined by the carpenter to allow the sliding assembly of the rod 1.  Io For this purpose, lights 12 are machined through the wall 11.  These lights have an oblong shape, complementary to the shape of the support pieces 2, that is to say composed of a lower part less wide under a wider central part, but of higher height, that is to say they are extended above their central part by an extension of elongated shape and of width substantially equal to the width of the lower part, so as to allow the insertion of the parts 2 through them, and their displacement in translation along the light in a selected direction, which is a downward direction in the embodiment shown in the figures.  In its central part, in correspondence of the control mechanism 6 carried by the rod, the upright 10 is machined, still on its front wall 11, to form an oblong slot 13 through which the movement control mechanism 6 can be inserted. of translation of the rod 1.  The rod 1 is mounted on the upright 10 of the leaf by insertion of the support parts 2 and the control mechanism 6 respectively in the slots 12 and 13 machined in the front wall 11 of the upright 10.  The configuration shown in FIG. 3 is thus obtained, in which the rod 1 is pressed against the front wall 11 of the upright 10 by its rear face 8.  The support parts 2 and the control mechanism 6 are then located almost entirely inside the hollow section of the upright 10.  The time required for the carpenter to mount the device according to the invention, as shown in FIG. 1, on a profile 10 as represented in FIG. 2, is approximately 20 to 25 seconds (excluding the time of machining of the lights in the profile 11).  This is quite satisfactory.  It is then sufficient for the carpenter, to finalize the assembly, to fix a handle secured to a control shaft of the mechanism 6 on the profile.  The engagement of the shaft on the mechanism 6 in this assembly makes it possible to ensure the cohesion and the maintenance of the device according to the invention in place on the upright 10.  When the handle is actuated, it triggers, through the control mechanism 6, the displacement in translation of the rod 1 along the wall 11 of the upright 10.  This displacement is enabled by the height of the apertures 12 and 13, which makes it possible to move, in the longitudinal direction of the rod 1, the support parts 2 and the control mechanism 6.  It causes the engagement of the hooks 3 on cooperating stops arranged on the amount of the frame.  A locking device according to the invention according to a different embodiment is shown in FIG.  This device allows bi-directional locking of the leaf, that is to say in two opposite directions.  In this embodiment, the device comprises two rod portions 1a and 1b, which may be identical or different, and which are intended to be mounted in extension of one another along the front wall 11 of the upright 10.  These two rod portions connect to a common central control mechanism which is conventional in itself and which is not shown in the figures, on which they are fixed at one end by means of screws inserted into respective orifices. 14a and 14b provided for this purpose.  A piece 2a, 2b support of a hook 3 is fixed respectively on each portion of the rod la, 1b.  The two pieces are fixed in such a way that their respective hooks 3a and 3b are oriented back-to-back with respect to one another.  The part 3b, intended to be fixed on the rod portion lb disposed below the other along the longitudinal axis of the rod portions, 5 is reversed relative to the part 2a fixed on the upper bead portion 1a.  In the embodiment shown in FIG. 4, the support piece 2b fixed on the rod portion 1b is of simple constitution, whereas the support piece 2a fixed on the bead portion 10 has a more complex shape, which will be described. in more detail below.  At their opposite ends, the two bead portions 1a and 1b are respectively extended by a rod 15a and 15b, at the respective end of which is a stop 17a, 17b.  These stops 15 are intended to cooperate with cavities formed in the side members of the frame which are contiguous to the upright 10 so as to further increase the strength of the locking of the leaf in the closed position.  The rods 15a and 15b are respectively fixed to the rod portions 1a and 1b by means of screws 16.  The support piece 2a mounted on the half-rod 1 shown on the top of FIG. 4 further comprises a stop stud 18 which protrudes on the front face 9a of the rod portion 1a, just above the hook 3a, and which is retractable through the thickness of the rod 1 and the front wall 11 of the upright 10.  This stud 18 prevents the translational movement of the rod portion 1a when the amount of the leaf 10 is not in abutment against the corresponding amount of dormant.  It is associated with two lateral shoulders 27 disposed on either side of the stud, which are slightly protruding from the front face 28 of the support piece 2a (this face being defined as the face opposite the rod 1 in the mounting configuration), and which are integral in retraction of the stud 18.  The profile 10 against which the device of FIG. 4 is to be fixed is machined in the manner shown in FIG. 5.  In addition to the two lumens 12a and 12b for respectively receiving the support parts 2a and 2b, the profile 10 is machined so as to have, still in its front wall 1, two longitudinal notches 20a and 20b respectively disposed at its longitudinal ends. opposed, and intended to receive the rods 17a and 17b extending the two rod portions la and lb.  The light 12a, which is intended to receive the support piece 2a, carrying the retractable stud 18, comprises in its upper part a bulge 26 in which the lateral shoulders 27 become blocked when the rod is mounted on the leaf upright, and as long as an effort to retract the stud 18 is not exerted on the latter.  This bulge 26 facilitates the removal of the stud 18 through the wall 11.  Once mounted on the upright 10, bearing against the longitudinal wall before 11 of the latter, the two rod portions la and lb are slidable, under the control of a common mechanism, in opposite directions, it is that is, in the embodiment shown in FIGS. 4 and 5, upwardly for the bead portion 1a and downwardly for the bead portion 1b, so as to respectively bring the hooks 3a and 3b engaged with the corresponding stops on the amount of dormant.  These simultaneous translational movements also cause the respective abutments 17a and 17b to be inserted into their cooperating cavities in the longitudinal members of the frame.  This results in a four-point locking of the amount of the leaf against the frame, which has a significantly improved security.  The support piece 2a, in its complex form, is shown in exploded perspective in FIG.  It shows the orifice 25 for the insertion of the fixing screws 5 to the rod 1.  The retractable stud 18 is inserted, so as to enclose a spring 19, inside a cavity 20 formed for this purpose at the upper end of the part 2a.  It is kept fixed in this cavity by clipping.  In its relaxed configuration, the stud 18 protrudes from the front surface of the part 2a, under the effect of the force exerted on it by the spring 19.  When the support member 2a is inserted into the corresponding lumen 12a on the upright 10, the stud 18 is held in place by wedging the lateral shoulders 27 in the bulge 26 of the lumen 12a, and therefore prevents the sliding of the workpiece. 2a up.  Thus, it is not possible to slide the rod portion la up, and thus bring the hook 3a to a height ensuring its engagement with the corresponding stop on the frame.  On the other hand, when the amount of the leaf rests against the corresponding amount of the frame, it exerts on the stud 18 a force tending to retract it inside the cavity 20, thus compressing the spring 19, and through the thickness of the rod 1 and the front wall 11.  This movement is facilitated by the presence of the bulge 26 near the upper edge of the lumen 12a.  The piece 2a is then free to slide upwards.  The movement of the hook 3a, and its engagement with the corresponding abutment on the frame, are thus permitted only when the amount of the leaf is properly supported against the amount of the frame.  This constitutes a safety element which ensures that the blocking can only be achieved in the suitably closed position.  The support part 2a also comprises means for allowing adjustment of the hook 3a.  It is in particular a screw 21 which fits partially in a groove 22 along the longitudinal edge of the rod 4a, and which fits into a housing 23 provided for this purpose in the support part 2a, as shown in Figure 6.  Adjusting the depth of insertion of the screw 21 inside the housing 23 ensures that the length of rod 4a protruding from the part 2a.  This is particularly useful for adapting to the different possible dimensions of the respective amounts of the leaf and the frame.  These adjustment means, and others that can be integrated into the support part 2a, are described in more detail in the document FR 2 823 522.  A different embodiment of the device according to the invention is shown in FIG.  The support piece 2c has a shape that is always generally elongated, but wider in its lower part than in its upper part.  The abutment stud 18 is integral in retraction with a locking element 29 which is disposed above it in the support part 2c.  The locking element 29 is inserted in a cavity 30 of this support part 2c, so that in the non-retracted position, it slightly protrudes from the front face 28 of the part 2c.  The support part 2c is intended to be mounted in a slot 12c machined in the front wall 11 of the leaf upright 10.  The lumen 12c has a shape complementary to that of the support piece 2c, i.e. oblong with a wider lower portion and a narrower upper portion, so that the piece 2c can be inserted through it. .  When the piece 2c has been inserted into the lumen 12c, and when no force is exerted on the stud 18 in view of its retraction, the blocking element 29 projects inside the lumen 12c, and rests against the upper longitudinal end wall 31 of the light.  When the leaf upright 10 is against against against the corresponding amount of frame, the stop stud 18 is retracted through the rod 1 and the front wall 11, and the locking element is retracted out of the light 12c , so that the translation movement of the rod 1 for locking is allowed.  This security is obtained with a form of light 12c which remains relatively simple and easy to machine.  An embodiment of the device according to the invention, which requires that a light of even simpler shape be machined in the front wall 11 of the door jamb, is illustrated in FIG. 8.  The support piece 2d has a substantially constant width over its entire height.  It comprises, on each of its lateral faces 32, two lateral lugs 33 substantially parallel to the longitudinal axis of the part 2d, but which are slightly inclined towards the outside of the part.  These tabs 33 are retractable to the body of the part 2d, to a position in which they are folded against the side faces 32 thereof.  The tabs 33 disposed on the same side face 32 are oriented in opposite directions relative to each other.  They have slices 40 bevel.  This support piece 2d is intended to be inserted into a lumen 12d machined in the front wall 11 of the leaf upright 10, which is of constant width over its entire height, as shown in FIG.  This width is slightly greater than the width of the part 2d, so as to allow the insertion of the latter through the light when the tabs 33 are folded against its body, but not when they project outwards.  A light having such a shape is particularly easy and quick to machine by the carpenter.  The insertion of the piece 2d in the lumen 12d is made in force, which has the effect of bringing the lateral lugs 33 30 against the body of the piece 2d and allow the passage of the latter in the light.  Once the piece 2d has passed through the front wall 11, the lateral lugs 33 move back again by themselves, and then prevent any movement behind the piece 2d, that is to say back to through the light 12d.  The device according to the invention then plays the same role as described above for the other embodiments of the invention.  A still different embodiment of the device according to the invention is shown in FIGS. 9 to 12.  The support part 2c is associated with a mounting plate 34 which is intended to be positioned between the rod 1 and the front wall 11 of the leaf jamb, fixed against the latter.  This plate 34 has a substantially rectangular outer contour.  It is in particular made of a metallic material.  A longitudinal slot 35 is pierced in the plate 34, for the passage of the support piece 2c through it.  This light has for this purpose a generally oblong shape complementary to that of the support part 2c, that is to say, in the embodiment shown in the figures, that it comprises a wider lower part and a part higher narrower.  At each of its two longitudinal ends 36, the plate 34 comprises a tab 37 which is substantially centered along the median line of the plate 34.  These tabs are slightly inclined with respect to the plane of the plate 34, in the direction of the door jamb in the mounting position, and they are retractable, that is, they can return to the plane of the plate. 34 under the effect of a force exerted on them.  This device is particularly adapted to be mounted on leaf uprights 10 having, in a conventional manner, on their front wall 1 1, longitudinal rails 38 for mounting a rod, as illustrated in FIG.  It is sufficient for the joiner to mount in the front wall 11 of the upright, between the two rails 38, a 12e 30 elongated complementary to that of the plate 34 but slightly lower surface.  The mounting plate 34, the width of which is intended to be substantially equal to the spacing between the two slideways 38, is then slidably passed between the slideways in the longitudinal direction of the upright until it coincides with the the light 12e, as shown in Figure 11.  During this operation, the tabs 37 of the plate 34 are held in force in the plane of the latter, which allows the sliding of the plate along the wall of the upright.  When the plate 34 coincides with the light 12e, the tabs 37 become free to move towards the inside of the light, and in doing so they bear respectively against the two longitudinal end walls 39 of the latter, as shown in Figure 12.  The mounting plate 34 is then automatically locked in the proper position, in coincidence of the light 12e.  It does not cross the latter because of the slight difference between the dimensions of these elements.  The passageway 35 of the plate is then in coincidence with the light 12e of the leaf upright 10.  It then replaces the lights 12 formed directly in the amount of leaf as described above, for mounting the support part 2c on this amount.  This solution makes it possible to ensure correct mounting of the support part 2c in the door jamb, while having the advantage of requiring an operation which is easy for the joiner, of machining a light of simple shape in the door jamb. leaf amount.  The mounting plate can easily be manufactured in series at the factory, and its positioning and attachment to the leaf post is quite easy and quick to perform.  The
