Description

 The invention relates to a cremone or espagnolette-lock, noting the multipoint type, comprising a control mechanism housed in a main housing and able to actuate one or more operating rods to ensure their displacement between a position for locking and unlocking, this or at least one of these operating rods acting, moreover, on at least one locking member in the form of a dead bolt or tilting, mounted, as the case may be, free in translation or in rotation, in a secondary housing disposed at the rear of a headrest.

 The present invention will find application in the field of building hardware.

 A number of cremones or cremo-locks are already known which correspond to the above description and which consequently include a control mechanism housed in a main housing and on which the user intervenes, for example by means of a key element or handle, for controlling in displacement ment one or more rods of maneuver extending, often, on both sides of this control mechanism.

 Note, in this regard, that it is common to implement this type of cremone or espagnolette lock in a notch extending into the edge of an opening of a door, window or the like. In these conditions, the or the rods of maneuver, arranged in this notch, come to be located, frequents, at the back of a headrest contributing to their maintenance and guidance.

 In the end, this or these operating rods have the function of acting on one or more locking members which, in the particular context of the present invention, are in the form of dead bolts and / or rocker bolts which , in the locking position, are able to emerge through an opening in the headrest to be housed in a striker arranged in concordance on the frame of said door, window or the like.

 In fact, such a dead bolt or rocking bolt is disposed in a housing mounted at the rear of said headrest, which housing, further enclosing the transmission or transmission members able to connect an operating rod to the bolt and, in addition, transforming a translational movement of the operating rod in a perpendicular movement of said dead bolt or in a rotation of a rocker bolt.

 Until now, such a secondary housing able to accommodate 1 'locking member in the form of a dead bolt or a rocker bolt is defined by a chest having a bottom provided and a peripheral wall preserving an opening on the side housing intended to be applied on the rear face of the headrest.

Said housing being completed by a lid which is not secured, the trunk, once the dead bolt or tilting and the transmission or transmission members mounted inside the trunk.

 In the end, we realize that this very design of the housing makes somewhat restrictive, not only its own assembly, but also the assembly of various parts that it is intended to contain.

 Thus, during this assembly it is essential to ensure a perfect positioning in the trunk, not only the dead bolt or tilting, but also the transmission members. In addition, we must ensure the maintenance of these 8 parts relative to each other. After that and at the very moment of positioning the cover, it is necessary, here again, to take a certain number of precautions to ensure that the various members are equally well arranged with respect to this cover, particularly with respect to the guiding means. translation and / or rotation that can be provided with the latter.

It is understood that, under these conditions, t t assembly of secondary housings born requires on the production and assembly line a complex and neat work. Moreover, if this assembly is not done by automated means, it is necessary to assign a qualified person to the workstation concerned, besides that, at the end of the assembly, a functional control is essential.

 In addition, this type of housing, for security reasons, requires the use of reinforcement devices which, most of the time, increase the dimensions of this housing, or even, in some cases, require the design of cremonesserrures. applied.

 Finally, it has been found that, in the past, the different parts forming said housings tended, in certain configurations, to play with each other to such an extent that the moving parts which they contained were more properly maintained or guided and caused disturbances or the blocking of the espagnolette or cremone lock.

 The invention proposes, therefore, to define secondary housings to obtain time saving during assembly, this, in particular, through a reduction in the number of parts that compose it. Apart from increased reliability this has the advantage of leading to a reduction in the cost price of the espagnolette or espagnolette lock.

 Finally, the present invention aims to remedy all of the aforementioned drawbacks through a one-piece design of such a secondary housing for receiving a locking member in the form of a dead bolt and / or tilting to It can even be operated by an operating rod of a cremone or espagnolette lock, in particular of the multipoint type.

 Thus, the assembly of the parts of such a housing which comprises, moreover, all the characteristics to maintain and guide them in displacement, is considerably facilitated and one can perfectly imagine to have the different parts inside of such a monoblock housing in an automated manner on the production line of the espagnolette or espagnolette-lock.

 In addition, unlike a two-part housing, that according to the present invention can be designed in tamper-resistant materials avoiding the use of complementary reinforcing devices.

 Finally, being designed in one piece, the characteristics of the latter are unlikely to evolve over time so that the guidance and maintenance of the moving elements inside of such a housing is provided permanently .

 Thus, the invention relates to a cremone or espagnolette-lock, including the multipoint type, comprising a control mechanism housed in a main housing and able to actuate one or more rods for maneuvering to ensure their movement between a locking position and an unlocking position, this or at least one of these operating rods acting, moreover, on at least one locking member in the form of a dead bolt or tilting mounted, as appropriate, free in translation or rotation, in a secondary housing disposed at the rear of a headrest, characterized in that said secondary housing is of the monobloc type and comprises two side walls secured to each other through a wall device preserving, in the front portion of the housing to be mounted on said headrest, an opening through which said dead bolt and / or tilting and its or organs transmission means intended to ensure its connection to the drive rod, are engaged in said housing, the latter further comprising means for holding and guiding said dead bolt or tilting.

 Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and nonlimiting example.

FIG. 7 schematically illustrates the various steps 1, 2, 3, 4 and 5 of the mounting of a locking member in the form of a rocker bolt in a casing and the installation of the last oe on a headrest.

 The invention relates, more particularly, cremonerrures 1 particularly multipoint type as shown in Figure 1 of the accompanying drawings.

 Such a cremone or espagnolette-lock comprises a main housing 2 enclosing a control mechanism (not visible), by the 1'-1'modiaire of which the user is able to act, for example by means of a key element or a handle, on one or more operating rods 3 to ensure their displacement between a locking position and an unlocking position. In fact, as can be seen in FIG. 1, this or these operating rods 3 can extend on one side or on either side of the main casing 2.

 This or these operating rods 3 act, moreover, on at least one locking member 4 which, in the particular case of the present invention is in the form of either a dead bolt 5 corresponding to the embodiment illustrated in FIGS. FIGS. 2 to 4, that is to say a rocking bolt 5A as seen in FIGS. 5 to 7. It should be noted, in this connection, that it is perfectly possible to imagine a locking member taking up, simultaneously, the characteristics of a dead bolt and a rocking bolt. If such a solution is little known, it should be considered, however, that it also fits into the singing of the present invention.

 This deadbolt 5 or tilting SA is, in fact, mounted, as appropriate, free in translation and / or rotation in a secondary housing 6 disposed at the rear of a headrest 7. More particularly, this headrest 7 has dimensions fitted to ocelles of the secondary housing 6 or extends, as has been shown in Figure 1, substantially over the entire length of the espagnolette-lock 1. At this headrest 7 are then made secured to all other secondary housings 6 as the main housing 2.

 To return to the secondary housing 6, accommodating a deadbolt 5 or a rocker bolt 5A, it is of the monobloc type, this in accordance with the invention. Thus, it comprises two side walls 8, 9 integral with each other through a peripheral wall 10 preserving, in the front portion 11 of this housing 6, an opening 12 through which lton can come engage said 5A or tilting 5A dead bolt, and its transmission member or members 13, 13A, intended to provide the connection with the operating rod 3. In fact, it is observed that the front portion 11, having the opening 12, is the which is intended to be mounted, by riveting, screwing or the like, on the headrest 7. Consequently, once fixed on the latter, said housing 6 can not, under any circumstances, deform or disassemble or present any game from which would result a bad maintenance to the guidance of the elements that it contains.

 In addition, such a one-piece housing 6 can be made by injection molding, or even by machining, ultimately allowing the use of resistant materials and / or capable of undergoing heat treatments or surface avoiding use reinforcement devices often essential in the context of non-monoblock housings and composed of several parts that should be assembled.

 Thus, the secondary housing 6, according to the invention, defines a housing 14 for accommodating the dead bolt 5 or the rocker bolt 5A, and its transmission member or 13, 13A.

It further comprises means for holding and guiding 16, 16A, respectively, of such a deadbolt 5 or a rocker bolt 5A.

 As can be seen in FIGS. 2 to 4, these holding and guiding means 16 are in the form of guide flanges 17 arranged in the housing 14 extending parallel to the axis of displacement 20 of said dead bolt 5, the latter taking position between these guiding flanges 17, 18.

 These holding and guiding means 16 can also take other embodiments, for example of the groove and / or groove type provided on the inner side 19 of one or more side walls 8, 9 and intended to cooperate, respectively, with a groove and / or a groove on the dead bolt 5, this or grooves and / or grooves extending in a direction parallel to the axis of movement of said dead bolt 5.

 The transmission member 13 is designed in the form of a bridge 21 housed in said secondary casing 6 and cooperating, by means of at least one attachment finger 22, with the operating rod 3. This bridge 21 is moves, therefore, in a direction parallel to that of this operating rod 3 and, therefore, perpendicular to the displacement of the dead bolt 5. More specifically, it comprises on at least one of its lateral faces 23, 24 a driving finger 25 which is housed in a light in the form of <Z 26 (visible in Figures 2 and 4), machined in the bridge 21 and ensuring the transformation of the movement of the latter into a perpendicular movement of the dead bolt 5 With regard to the drive finger 25, it corresponds to an axis passing through the dead bolt 5 and projecting on one or the lateral faces 23, 24 of the latter.

 Preferably, the bridge 21 is split in its portion 27 comprising the Z-shaped light 26> 26, so as to act on both sides on the dead bolt 5 which comprises, under these conditions, on each of its faces laterally 23, 24 such a drive finger 25 corresponding in fact to the projecting ends of an axis passing through the dead bolt 5. It will be observed, in this connection, that the application of a lateral force on only one of the sides of the bolt 5, tends to cause, because of the slight play of operation too much friction. The preferred embodiment using a split bridge 21 allows, therefore, to avoid this phenomenon.

 It should be noted, moreover, according to a feature of the present invention, that the free end 28, 29A of the axis defining this or these driving fingers 25, moves in a transverse groove 29 (parallel to the axis of displacement 20 of the dead bolt 5) formed on the inner side 19, as the case, the side wall 8 and / or 9 of the secondary housing 6. It is understood, under these conditions, that it becomes completely impossible, even following at multiple stresses, the bridge 21 is detached from the dead bolt 5.

 FIG. 4 schematically illustrates the various steps of mounting 1, 2, 3 of such a dead bolt 5 and its secondary housing 6 on the headrest 7 of a cremone or espagnolette lock 1.

More precisely once the easel 21 hooked on the dead bolt 5, the assembly is simply slid inside the secondary housing 6 through the opening 12 that has in its front part it. Then comes to ensure the cooperation between the attachment finger 22 of the bridge 21 with the operating rod 3 before fixing said secondary housing 6 on the headrest 7 preferably by riveting.

 As for the holding and guiding means 16A of a rocker bolt 5A in such a single-piece secondary casing 6, they consist of a simple axis 30 extending perpendicularly to the inside of the secondary casing 6 and on which is mounted, in rotation, said rocker bolt 5A. More precisely, at least one of the side walls 8, 9 of said secondary housing 6 comprises an orifice 31 fitted to the passage of this axis 30, this orifice 31 coming to be situated at the level of a bore 32 formed in the rocking bolt 5A when it is disposed inside said secondary housing 6. Thus, during assembly, this shaft 30 is engaged, successively in this orifice 31, then in the bore 32. This movement is continued until its end 33 is housed in another hole in the opposite wall of said secondary housing 6 or in a simple cavity on the inner side 19 of the opposite wall. Ultimately, a crimping or riveting performed at the or openings 31, present in the side wall or walls 8, 9 of the housing 6 prevents any risk of unexpected disassembly of the axis 30.

 It will be observed that with respect to the transmission member 13A it borrows a configuration similar to that of the transmission member 13 intended to act on a dead bolt 5. However, in this case, the easel 21 has in its portion 27 split, a drive shaft 25A while said rocker bolt 5A has him, a comma-shaped light 26A through, precisely, by this drive axis 25A.

The interaction between oet drive axis 25A and this light 26A, during the movement of the bridge 21 under the influence of an operating rod 3, precisely leads to the tilting of the bolt 5A in a locking or unlocking position .

 The assembly and assembly operations are, also, little different from those to which reference has been made in relation to a locking member in the form of a dead bolt 5.

 Thus, as can be seen in FIG. 7, firstly the easel is hooked onto the rocker bolt 5A, this assembly is then inserted into the secondary casing 6 through its opening 12 present in its front part 11. However, it is appropriate, however, to mount the axis 30 substantially constituting the holding and guiding means 16A of the rocker bolt 5A. Finally, it comes to ensure cooperation between the operating rod 3 and the bridge 21 before fixing, in particular by riveting, said secondary housing 6 on the headrest 7.

 Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. various elements without departing from the scope and spirit of the invention.
