Description

The invention relates to a cremone-barrel for door, window or the like as defined in the preamble of claim 1.

The present invention relates to the field of building hardware and relates, in particular, to cremones whose locking condemnation is via cylinder key cylinder, more commonly referred to barrel cremones.

We already know a number of cylinder cremones as described above which, if they provide satisfaction with the locking function they provide, have the disadvantage of integrating a mechanism complex control system consisting of a multitude of moving parts with a non-negligible operating clearance. This results in an action on the locking members, such as operating rods which are difficult to finely control the stroke, otherwise unequal to one rod relative to another, so that, in addition to the dimensional constraints of manufacturers of windows, many adaptations are necessary for a good integration of such a cremone-barrel at the level of a carpentry, type door, window or other.

In particular, through this clearance of the control mechanism, variations may exist in the stroke communicated to these operating rods between the unlocked position and the locking position. However, because of current developments that try to reduce the rebate games between frame opening and frame of a door or window, these races communicated to the rods maneuver must be perfectly mastered.

If, in addition, a large functional clearance can be the cause of a locking defect of the espagnolette barrel, it also raises the problem of the stability of the parts, relative to each other, in a reference position to ensure assembly as a fitting fitting of such a cremone-barrel factory, on the one hand, and, secondly, on a carpentry, taking into account that during this assembly this barrel cremone can be brought to cooperate with complementary locking elements contributing, for example, to a perimetral locking of an opening.

In fact, to ensure that these parts of a control mechanism of a barrel cremone retain this position of reference during these assembly operations at the factory and assembly in a user, it is common to immobilize through temporary blocking means, which can be removed or destroyed at the end of assembly.

It is however common that such temporary blocking means are retracted prematurely, so that the previously mentioned problems persist. Note, in this regard, that such temporary locking means, often in the form of breakable plastic studs, are usually for single use. In short, they can not be made active again after their effects have been annihilated through, for example, erroneous manipulation.

Thus, it is known a barrel cremone comprising, housed in a housing, a drive mechanism consisting, in particular, of a follower provided in its center with an opening for the reception of a maneuvering square on which is likely to act the user through a control handle.

By means of a suitable toothing, this follower is able to act on an easel connected to an operating rod, knowing that in the case of a barrel bolt with rods bidirectional an inverter transmission mechanism echoes the movement in an opposite direction on a second drive rod. With a control finger this follower is still defined able to act on the tail of a latch bolt with elastic return in the locking position, taking into account that the follower is itself subject to the action of return means elastically to bring it systematically into a reference position and, consequently, the handle through which it is driven.

With the help of the barrel, so a key, that includes such a cylinder-bolt is to act on a locking bolt whose primary function is to ensure the locking of the operating rods in the locking position. In certain configurations, it can also define a deadbolt by extending beyond the front face of a headrest which is secured to the casing of the cylinder-cylinder and behind which move said maneuvering rods.

Finally, it will be observed that this drive mechanism made complex by the multiplicity of parts that compose it, is made to take position in a housing whose size must be defined as low as possible to be able to integrate into amounts book, door or window type, particularly small section.

In this context, we still know from the document FR-A-2744480 , a barrel cremone comprising a housing in which takes position a key cylinder with a bit, and a follower adapted to be actuated by a handle for driving a bolt and two locking rods to opposite displacement.

These locking rods are guided longitudinally by the headrest on both sides of the housing.

In fact, the two rods are actuated by a rotatable transmission part, integral in rotation with the follower and to which is connected, in an articulated manner, a first end of a rod whose opposite end is still mounted articulated on a toothed wheel double able to operate jointly the two rods.

This espagnolette also has a locking mechanism in the form of a part mounted in rotation between the follower and the barrel. In particular, through the bit fitted to the latter, this rotating part is likely to occupy a first locking position and a second unlocking position, knowing that in the first position it cooperates with a stop that includes the follower, preventing, thus, the rotation of the latter under the impulse of the handle.

Finally, it is still a problem that these cremone-barrels must respect well-defined dimensions at the distance separating the axis of the follower and the front face of the headrest housing the rods maneuvering.
It is easy to understand that moving the follower towards the inside of the housing to enable it to comply with an imposed dimension inevitably affects all the parts of the drive mechanism.

Also, to the problem posed by the multiplicity of parts that compose the drive mechanism abounds that of the multiplicity of mechanisms to allow these barrel cremone-bolts to suit sections of amounts of dormant and various opening.

To this must be added that these different constraints require, very often, to extract and deport with respect to the housing of the drive mechanism certain functions such as, for example, the reversal of movement that allows a mono cremone directional to provide bidirectional movement to operating rods.

In order to be able to respect the fuzzy dimension in the case of joineries with profiles of very small section, it is also necessary, usually, to come to occupy, in part, the rebate clearance between opening and sleeping, or even another adjacent opening, to be able to fit all the parts of the drive mechanism into the housing. It is then necessary to conform accordingly the headrest arching it to the height of said housing.

It is also very difficult, to meet all these requirements, to design barrel cremones able to agree, at the same time, an application to the left and right.

Moreover, to meet these heavy specifications, it is so far useful to use multiple manufacturing techniques, such as stamping, foundry, cutting, but it is also necessary to perform an assembly step by step, with preliminary assemblies of under and executions of various operations of riveting, screwing, etc ...

Finally, by reconsidering a barrel cremone and in particular its operation, the present invention was able to respond to the aforementioned problems. Firstly through a housing subdivided into two parts, including a first part, located in the immediate vicinity of the headrest, which is of variable volume and therefore only accommodates parts that reflect transmission functions, in particular on the operating rod or rods located at the rear of said headrest, but also various functions such as braking, indexing, etc ... on control parts which, they, in a second part, achieve a constant volume located at the rear of the housing, or beyond the variable volume.

This allows, therefore, a very easy adaptation of these barrel cremones to a determined follower rating. More exactly, the separate pieces according to this fuzzy dimension are reduced to a minimum. The invention leads, again, to a simplification of the drive mechanism of such a cremone-barrel, simplification having the effect of reducing, significantly, the functional games.

Under these conditions, it is still conceivable to ensure, in the locking position, a direct locking of the follower via the key cylinder, insofar as this blocking is reflected, with a minimum clearance, on said rods, then perfectly locked in this locked position.

Moreover, through parts of the drive mechanism taking position in the case of the housing by successive stacking, the invention has also been able to respond to assembly constraints encountered so far.

Thus, the invention relates to a cylinder cremone as defined in claim 1

According to another feature, in said second part of the housing the trunk comprises braking means provided adapted to cooperate with at least one bridge corresponding to a transmission part to ensure the maintenance of said operating rods in the locking position and / or unlocking in the absence of impulse on the follower.

According to another feature, in said second part the housing, in particular the trunk, comprises indexing means provided adapted to cooperate with complementary indexing means at the wheel lock so as to index the locking positions and unblocking of the latter. This results in an indexing, click-clack type, directly felt by the user through the key.

According to another feature, the tail of the latch bolt comprises fastening means provided adapted to cooperate, with complementary fastening means housed in said trunk and retractably designed against the action of elastic means of rappelling, for allow the stall and extraction of said latch bolt of the housing to ensure its reversal for left or right application of the barrel cremone.

Advantageously, the housing comprises an opening allowing access, through a control member such as a screwdriver, to said additional hooking means to retract the latter against the action of said elastic rappelling means.

Advantageously, or the trestle comprises two defined drive branches adapted to cooperate with an operating rod symmetrically to the longitudinal median plane of the latter.

In particular, the component parts of the mechanism are designed to be arranged by stacking in the trunk of the housing.

As shown in the figures of the accompanying drawings, the present invention relates to a barrel cremone 1 for door, window or the like. It comprises, housed in a housing 2, a drive mechanism 3 for acting on at least one latch bolt 4 and bi-directionally on operating rods 5, 6 extending respectively above and below the housing 2.

In the end these operating rods 5, 6 come to move at the rear of a headrest 7 which is defined able to be secured to the housing 2 designed by a box 8 whose bottom 9 defines one of the side walls of the housing 2, knowing that this box 8 is closed by a cover 10 corresponding to the other side wall and extending, therefore, parallel to the plane of the opening of the door or window which is equipped with said cremone-barrel 1.

The trunk 8 has a peripheral rim 11 defining the upper face 12, the lower face 13 and the rear face 14 of the housing 2 knowing that in the front part 15 it is closed through the headrest 7. In this regard at this level. front part 15, the trunk 8 has housing 16 receiving fastening screws 17 through appropriate openings 18 in said headrest 7.

In fact and according to the invention, the housing 2 is subdivided into a first part 2A of substantially constant volume accommodating the control parts 3A of the mechanism 3 and a second part 2B interspersed between the previous and the headrest 7 and which is, it, of adjustable volume and receives the transmission parts 3B of this mechanism 3.

It is clarified once again that the name complements used to identify the parts taking position in this first and second part of the case, namely control and transmission, have the sole purpose of distinguishing these parts according to their arrangement in the case and have no limiting character from the point of view of the very function of these parts.

It comprises a follower 19 having in its center a passage 20 for receiving a maneuvering square corresponding to a handle through which a user can control this follower 19 in rotation.

More specifically, it comprises a central hub 21 whose ends are held in rotation through openings of adjusted section 22, 23 in the side walls of the housing 2, or at the bottom 9 corresponding to the trunk 8 and in the cover 10, particularly in the part 2A of the housing 2.

If, as will be explained further in the description, this follower 19 is designed to act on the latch bolt 4 through a control finger 24, it is also subject to recall means resilient 25 in a reference position 26 corresponding to a given position of the handle accessible to the user.

More particularly, under the action of these elastic return means 25 and regardless of the direction of rotation communicated to the follower 19, so the handle, it is systematically returned to its initial position, often horizontal.

According to the invention, these resilient return means 25, commonly called kickstand return spring, are defined by a pusher 27 subjected to the action of a return spring 28 provided adapted, in cooperation with driving fingers 29 , Associated with said follower 19, to exert on the latter a return torque in said reference position 26, as soon as this follower 19 deviates from the latter, by rotation in one direction or another.

More precisely and as visible in the figure 11 , the pusher 27, under the action of the spring 28, is defined capable of exerting its thrust in a radial direction 31 to the follower 19, while that the driving fingers 29, 30 with which it cooperates are themselves symmetrically disposed on either side of this radial direction 31 and at a determined distance from the axis 32 of the follower 19.

Thus, during a rotation of the latter in one direction or another these drive fingers 29, 30 act on the pusher 27 against the action of the spring 28.

Advantageously, the pusher 27 comprises, facing the driving fingers 29, inclined planes 33, 34 conferring on it a defined V-shaped structure capable of guaranteeing a substantially constant compression of the spring 28 under the action of the fingers of FIG. 29, 30 during this rotation of the follower 19, they define the reference position 26.

Finally, as is visible in this figure 11 in this rest position, referred to as reference 26, of the follower 19, the pusher 27 exerts an equal pressure on these driving fingers 29, 30, thus antagonistic pairs ensuring the immobility of said follower 19.

It is to be observed that it is here again in part 2A of constant volume that the pusher 27 and its spring 28 take up position, where they are, moreover, held and guided by appropriate means 27A which defines more particularly the bottom 9 of the chest 8.

Moreover, and as has been shown in more detail in the figure 12 on the follower 19 comes to mesh, with a determined idle stroke 35, an inverting wheel 36 corresponding to a control part 3A of the mechanism 3 and to which are connected, diametrically opposite two trestles 37, 38 able to ensure the retransmission of its rotation in linear form to the operating rods 5, 6. These easels 37, 38 are parts of transmission 3B of the mechanism 3, so that they pass through the adjustable portion 2B of the housing and as such are themselves adjustable in particular according to the dimension of the follower 19, distance between the axis of the latter of the headrest 7 .

More particularly, this inversion wheel 36 comprises, substantially diametrically opposite, driving lugs 39, 40 on which are engaged oblong slots 41, 42 which are formed in these trestles, 37, 38 respectively. made these oblong slots 41, 42 extend substantially transversely relative to the displacement thereof.

Advantageously, the trestles 37, 38 are defined able to reflect their movement and, therefore their efforts, symmetrically on the operating rods 5, 6 considering the longitudinal median plane of the latter.

More precisely, these trestles 37, 38 comprise two "U" -shaped drive legs 45, 46 each provided with at least one connecting tongue 47, 48 on one of the walls of the "U" defined as suitable to cooperate with a cutout 49 adjusted accordingly and symmetrically to the longitudinal median plane at the level of said rods 5, 6.

Advantageously, the portion 2B of the housing 2 defines, through the walls 9, 10 which delimit it, means for guiding these trestles 37, 38. More particularly, the spacing of the two drive legs 45, 46 corresponding to these trestles is adjusted to that of said walls 9, 10.

This guiding function can be completed by the part 2A of this housing 2. In particular, the bridge 38, on which the inversion wheel 36 acts by means of its driving pin 40 furthest from the the axis of operating rods 5, 6, comprises a guide tongue 43 defined to cooperate with a guide slot 44 formed in the rear face 14 of the housing 2.

This arrangement makes it possible, in particular, to counteract the transverse component forces exerted on this bridge 38 because of this distance between the driving pin 40 and the axis of the operating rods 5, 6.

To come back to the idle stroke 35 to which reference has been made previously, it is defined with an amplitude corresponding substantially to the angular stroke that can be imparted to the follower 19, for example to ensure its return to the position of reference from that conferred on it to obtain the locking of the operating rods 5, 6. Of course, this vacuum run 35 still applies in other situations.

It stems, substantially, from a cut 51 made on a sector 52 at the periphery of the follower 19, cutout in which is inserted a control finger 53 corresponding to the inverting wheel 36. As a result, the vacuum stroke 35 corresponds to the displacement likely to be communicated to the follower 19 to bring said control finger 53 of the reversing wheel 36 in cooperation with a stop plane 54, 55 delimiting laterally said cutout 51 in the follower 19, this starting from the opposite stop plane , respectively, 55, 54.

Advantageously, again, under the effect of the control of a cylinder 57 a lock wheel 56 forming part of the control parts 3A is provided capable of cooperating with the reversing wheel 36 to ensure its locking in rotation and, by way of consequently, preventing the unlocking of the operating rods 5, 6 under the impetus of the follower 19.

In a conventional manner, the bolt of the cylinder, under the effect of the rotation of a key, is part of a cutout 58 of this wheel lock 56 rotatably mounted under the inversion wheel 36 about an axis parallel to the axis of the latter therefore the follower 19. It follows that the lock wheel 56 is provided capable of occupying a first locking position 59 and an unlocking position 59A. In the blocking position 59, it comprises a blocking tooth 60 fitting into a recess 61 of conjugate shape at the level of the reversing wheel 36. This blocking tooth 60 thus offers a stop plane 62 cooperating with a corresponding stop plane 63 at this recess 61 of the reversing wheel 36 preventing it from being pivoted in the direction of unlocking.

Advantageously, the follower 19, the inverting wheel 36 and the locking wheel 56 are located in the part 2A of the housing 2, substantially in the same alignment parallel to the headrest 7.

In addition, this portion 2A of the housing 2, in particular the trunk 9, comprises indexing means 64 adapted to cooperate with complementary indexing means 65 at the wheel lock 56 so as to index the locking positions 59 and release 59A of the latter.

Preferably, the intervention of the control finger 24 corresponding to the follower 19 on the latch bolt 4 or, more particularly, the tail 66 of the latter, is not done directly, but via a lever control device 67 defining, advantageously, additional retractable hooking means 68 adapted to cooperate with hooking means 69 associating with said tail 66 of the latch bolt 4.

In particular, the housing 2, for example the lid 10, has an opening 70 designed to allow access to a suitable tool, such as a screwdriver or the like, to these complementary hooking means 68 to push them away, against the action of elastic return means 71, in a retracted position relative to the attachment means 69 of the shank 66 of the latch bolt, allowing removal of the latter from the housing 2 and its overturning for an application of the cremone-barrel as the case to the right or left.

It should be observed, in this connection, that the tail 66 of the latch bolt 4 is designed symmetrically with respect to its longitudinal axis 72.

Thus, regardless of the direction of the latch bolt 4, the tail 66 has, at its rear end 73 and at its upper edge 74, a cutout 75 defining, substantially, the attachment means 69 and in which can a drive lug 76 which comprises the control lever 67 corresponding to the complementary fastening means 68 is housed. Note that the free end proper of this tail 66 of the latch bolt 4 is defined in a tapered form of suitably, during the establishment of the latch bolt 4 in the housing 2, to push the control lever 67 against the action of the elastic return means 71 to allow the engagement of the driving pin 76 in the cut 75.

To return to this control lever 67, visible in the figures 4 , 8 and 13 , if it cooperates with the control finger 24 of the follower 19 through an end 77 located on one side of the transverse median plane 78 to the latch bolt 4, it is hingedly mounted, at its opposite end 79, on the other side of this transverse median plane 78, on a pivot 80 extending from the bottom 9 of the trunk 8.

In fact, at this end 79 the control lever 67 has an oblong slot 81 conferring relative mobility relative to said pivot 80 and allowing it to occupy an active position corresponding to the engagement of the driving pin 76 in the cut 75 of the tail 66 of the latch bolt 4, and a retracted position where this driving pin 76 is clear of this cutout 75.

In the end and as indicated above, it is through a tool, such as a screwdriver, that the control lever 67 can be pushed into this retracted position, knowing that through the opening 70 in the housing 2 this tool can be engaged in a corresponding opening 70A provided for this purpose in this control lever 67.

Furthermore, this position can only be achieved by acting against the action of elastic return means 71.

Advantageously, it is the same elastic return means acting on the tail 66 of the latch bolt 4 to bring it systematically in the advanced locking position.

Thus, said elastic return means 71 are defined by a stressed spring 82, one end 83 of which is provided capable of acting on the control lever 67 and / or on the end 73 of the tail of the latch bolt 4 to push back. this one in its advanced locking position. Furthermore, the other end 84 of this spring 82 is defined able to come to rest on the control lever 67 so as to print an axial thrust having the effect of maintaining it in its active position, ie that the complementary attachment means 68 that it defines cooperate with the attachment means 69 corresponding to the tail 66 of the latch bolt 4.

The control lever 67 and the elastic return means 71 are considered to be part of the control parts 3A and take up position in the constant volume portion 2A of the housing 2.

According to another feature of the present invention, the housing 2 comprises in its part 2A braking means 85 defined capable of ensuring the maintenance of the operating rods 5, 6 in a specific position. In fact, these braking means 85 have the function of preventing that, brought, for example, in the locking position and before intervening the locking with the key, these operating rods 5, 6 fall back into the unlocked position.

While it would be true that it would prevent the locking with the key, this function of braking also has its importance during the assembly of the cremone-barrel on a carpentry. Indeed, they ensure that during this assembly said operating rods 5, 6 retain a specific position which depends, usually the conditions of assembly of complementary members to the lock fitting. Indeed, during this assembly, the barrel is removed and can not provide the blocking function that is normally assigned to it so that it was used, very frequently, temporary blocking studs that ensured relative immobility of the rods compared to the headrest. Such studs being provided with a breakable element, a first operation has the consequence of annihilating their function.

Through the present invention, such studs are not only useless, but, in addition, the braking means 85 applied here remain functional throughout the life of the barrel cremone and thus ensure a better operation. of the latter in time.

In particular, said braking means 85 are in the form of an elastic blade 86 associated with said housing 2 and defined adapted to cooperate with a bridge 37.

This elastic blade 86, together with a bearing wall 87 extending parallel to the plane of the rods 5, 6 in the trunk 8 of the housing 2, acts in the manner of a clamp in which is defined able to come s' engage a connecting wall 88 corresponding to the bridge 37 and connecting the two drive legs 45, 46.

According to another feature, the barrel cremone 1 comprises indexing means of the unlocked position and / or locked of the or said operating rods 5, 6. Advantageously, these indexing means are defined, on the one hand, by a boss 86A that includes the elastic blade 86 at its end and, on the other hand, one or more openings 89 and / or cavities in said connecting wall 88 of the bridge 37. Thus, depending on whether the latter occupies one and or the other position corresponding to the unlocked and / or locked of the or said operating rods 5, 6, the boss 86A comes register in such an opening or cavity 89.

It is specified that the two drive legs 45, 46 of the trestles 37, 43 have a length defined as a function of the follower dimension 19.

Advantageously, the trunk 8 of the casing 2 is made by injection molding made of plastic or zinc alloy, this box containing all the functionalities necessary for the positioning and maintenance of the parts of the drive mechanism 3.
