Abstract

The catch consists of a control mechanism (2) with at least one toothed wheel (6) which meshes with a rack (7) linked to or made part of a moving rod (3). The rack is made by bending part of the metal strip (18) which forms the rod into a series of undulations (20) shaped to engage with the teeth on the wheel (6). The toothed wheel also carries a catch (13) which projects from the edge of the door/window at the same time as the rod is actuated by the handle. The toothed wheel has a second set of teeth (26) opposite the first to engage with apertures (24) in a second rod (4).

Description

L'invention concerne une crémone ou crémone-serrure comprenant un mécanisme de commande muni d'au moins une roue dentée constituant le fouillot sur lequel peut intervenir l'usager par l'intermédiaire d'une poignée de commande, cette roue dentée, d'une part, agissant sur une crémaillère aménagée, soit sur un chevalet relié à une tringle de manoeuvre, soit sur cette dernière et, d'autre part, comportant, sur son pourtour, un pêne de verrouillage à même de se présenter saillant par rapport à la face externe d'une têtière à l'arrière de laquelle s'étendent la ou les tringles de manoeuvre.The invention relates to a cremone bolt or cremone bolt comprising a control mechanism provided with at least one toothed wheel constituting the follower on which the user can intervene by means of a control handle, this toothed wheel, on the one hand, acting on a fitted rack, either on an easel connected to an operating rod, or on the latter and, on the other hand, comprising, on its periphery, a locking bolt capable of being protruding relative to the external face of a headrest at the rear of which extend the operating rod or rods.

La présente invention trouvera son application dans le domaine de la quincaillerie du bâtiment.The present invention will find its application in the field of building hardware.

En fait, l'on connaît déjà, notamment par le document EP-A-0.207.869 des crémones ou crémones-serrures répondant à la description ci-dessus, mais qui présentent, à l'heure actuelle, un certain nombre d'inconvénients liés au mode de transmission d'un mouvement du mécanisme de commande sur un chevalet ou, tout particulièrement, sur une tringle de manoeuvre qui est, par ailleurs, fragilisée en raison des contraintes mécaniques.In fact, we already know, in particular from document EP-A-0.207.869 cremone bolts or lock bolts corresponding to the above description, but which presently present a certain number of drawbacks linked to the mode of transmission of a movement of the control mechanism on an easel or, in particular, on an operating rod which is, moreover, weakened due to mechanical stresses.

Ainsi, dans le cas des crémones ou crémones-serrures que l'on pourrait qualifier de classiques, c'est-à-dire qui ne sont pas dans l'obligation de respecter des conditions dimensionnelles strictes, l'entraînement d'une tringle de manoeuvre par l'intermédiaire du mécanisme de commande de cette crémone ou crémone-serrure s'effectue au moyen d'une roue dentée agissant sur un chevalet lui-même relié, par des moyens de fixation appropriés, à la ou les tringles de manoeuvre. A noter qu'en ce qui concerne la roue dentée, celle-ci peut constituer notamment le fouillot sur lequel agit l'usager par l'intermédiaire d'un carré de manoeuvre. Dans ces conditions, le chevalet comporte une crémaillère qui, précisément en raison d'une largeur suffisante du plat métallique constituant ce chevalet, peut emprunter différentes configurations. Notamment, dans ce plat métallique peuvent être aménagées, par exemple par emboutissage, une succession d'ouvertures séparées par des barreaux transversaux et sur lesquels vient s'engréner la denture de la roue dentée précédemment citée. Il se peut, également, qu'au niveau d'un des bords latéraux de ce chevalet soit réalisée une succession de découpes de manière à définir une denture permettant, là encore, l'entraînement au moyen d'une roue dentée tel qu'un fouillot.Thus, in the case of cremone bolts or bolts that could be described as classic, that is to say which are not required to meet strict dimensional conditions, the driving of a rod operation by means of the control mechanism of this cremone bolt or cremone bolt is effected by means of a toothed wheel acting on an easel itself connected, by appropriate fixing means, to the maneuvering rod or rods. Note that with regard to the gear wheel, this can in particular constitute the follower on which the user acts through a maneuvering square. Under these conditions, the bridge has a rack which, precisely because of a sufficient width of the metal plate constituting this bridge, can take different configurations. In particular, in this metallic dish can be arranged, for example by stamping, a succession of openings separated by transverse bars and on which the teeth of the previously mentioned toothed wheel mesh. It may also be that at one of the lateral edges of this easel, a succession of cuts is made so as to define a toothing allowing, here again, the drive by means of a toothed wheel such as a follower.

Bien sûr, ce même type de configuration peut se présenter au niveau d'une tringle de manoeuvre.Of course, this same type of configuration can occur at the level of an operating rod.

En réalité, les problèmes se posent lorsque cette crémaillère doit être aménagée sur un chevalet, tout particulièrement, sur une tringle de manoeuvre à un endroit où celle-ci est fragilisée en raison d'une ouverture servant de passage à un organe de fixation ou encore à un organe de verrouillage. Plus particulièrement, dans de telles conditions et en raison de l'ouverture dans ladite tringle de manoeuvre ou, éventuellement, le chevalet, celle-ci ou celui-ci n'est défini, à cet endroit, que par des branches de largeur très réduite dans lesquelles on ne peut réellement envisager d'emboutir des ouvertures pour la conception d'une crémaillère ou, pire, d'usiner des découpes dans l'un de leurs bords latéraux. En effet, une telle tringle ou un chevalet ainsi fragilisé à l'extrême ne saurait résister aux contraintes qui lui sont imprimées par le mécanisme de commande au moment du verrouillage.In reality, the problems arise when this rack must be fitted on an easel, in particular, on an operating rod at a place where it is weakened due to an opening serving as a passage for a fixing member or else to a locking member. More particularly, under such conditions and due to the opening in said operating rod or, possibly, the easel, this or this one is defined, at this location, only by branches of very reduced width in which one cannot really consider stamping openings for the design of a rack or, worse, machining cutouts in one of their lateral edges. Indeed, such a rod or easel thus weakened to the extreme can not withstand the stresses which are imparted to it by the control mechanism at the time of locking.

De même l'épaisseur du plat métallique composant le chevalet ou encore la tringle de manoeuvre est insuffisante pour que l'on puisse songer à entailler, sur l'une de leurs faces, une denture quelconque, sans apport de matière sous forme d'une pièce additionnelle rapportée sur ce chevalet ou cette tringle de manoeuvre.Likewise, the thickness of the metal plate making up the easel or even the operating rod is insufficient for one to think of notching, on one of their faces, any teeth, without the addition of material in the form of a additional piece attached to this easel or this rod.

On notera que la résolution de ce problème a entraîné dans le cadre de la crémone décrite dans le document antérieur EP-A-0-207.869, le déport vertical du pêne de verrouillage par rapport à l'axe de rotation du fouillot. De plus, il convient d'observer que, dans ce cas d'espèce, l'on est en présence d'une crémone à mouvement bidirectionnel, de sorte que la discontinuité entre les tringles de manoeuvre à hauteur du mécanisme de commande évite l'aménagement d'une ouverture dans l'une d'elles pour le passage du pêne de verrouillage porté par le fouillot.It will be noted that the resolution of this problem has resulted in the cremone bolt described in the prior document EP-A-0-207.869, the vertical offset of the locking bolt relative to the axis of rotation of the follower. In addition, it should be observed that, in this case, we are in the presence of a lever with bidirectional movement, so that the discontinuity between the operating rods at the height of the control mechanism avoids the arrangement of an opening in one of them for the passage of the locking bolt carried by the follower.

A cet effet, l'invention concerne une crémone ou crémone-serrure comprenant un mécanisme de commande muni d'au moins une roue dentée constituant le fouillot sur lequel peut intervenir l'usager par l'intermédiaire d'une poignée de commande, cette roue dentée, d'une part, agissant sur une crémaillère aménagée, soit sur un chevalet relié à une tringle de manoeuvre, soit sur cette dernière et, d'autre part, comportant, sur son pourtour, un pêne de verrouillage à même de se présenter saillant par rapport à la face externe d'une têtière à l'arrière de laquelle s'étendent la ou les tringles de manoeuvre, caractérisée par le fait que le pêne de verrouillage se situe dans le plan médian vertical de la roue dentée, celle-ci comportant une denture de part et d'autre du pêne de verrouillage, tandis que le plat métallique correspondant au chevalet ou à la tringle de manoeuvre destinée à coopérer avec ces dentures, comporte une ouverture servant au passage du pêne de verrouillage et délimitée, de part et d'autre, par des branches munies d'une crémaillère définie par déformation dudit plat métallique conférant à ce dernier une ondulation sur les bossages de laquelle sont à même de s'engréner lesdites dentures de la roue dentée.To this end, the invention relates to a cremone bolt or bolt lock comprising a control mechanism provided with at least one toothed wheel constituting the follower on which the user can intervene by means of a control handle, this wheel toothed, on the one hand, acting on a fitted rack, either on an easel connected to an operating rod, or on the latter and, on the other hand, comprising, on its periphery, a locking bolt capable of presenting itself protruding from the external face of a headrest at the rear of which extend the operating rod or rods, characterized in that the locking bolt is located in the vertical median plane of the toothed wheel, this ci comprising a toothing on either side of the locking bolt, while the metal plate corresponding to the easel or the operating rod intended to cooperate with these toothing, has an opening serving for the passage of the bolt locking and delimited, on both sides, by branches provided with a rack defined by deformation of said metal plate giving the latter an undulation on the bosses of which are able to mesh said teeth of the toothed wheel.

Les avantages obtenus grâce à cette invention consistent en ce que la crémaillère, conçue au travers d'un procédé de déformation de la matière, contrairement aux procédés antérieurs, n'a pas pour conséquence de fragiliser le chevalet ou la tringle de manoeuvre. Bien au contraire, une telle crémaillère contribue à renforcer leur tenue mécanique de sorte que l'on peut parfaitement imaginer concevoir un entraînement ne s'effectuant que sur des branches d'une portion fragilisée du plat métallique correspondant à un tel chevalet ou à une telle tringle de manoeuvre.The advantages obtained thanks to this invention consist in that the rack, designed through a process of deformation of the material, unlike the previous processes, does not have the effect of weakening the easel or the operating rod. On the contrary, such a rack contributes to strengthening their mechanical strength so that one can perfectly imagine designing a drive taking place only on branches of a weakened portion of the metal plate corresponding to such an easel or to such a operating rod.

L'invention sera mieux comprise à la base de la description qui suit accompagnée des dessins représentant un exemple de réalisation.

  • . la figure 1 est une vue schématisée et en coupe partielle d'une crémone à double direction dont une des tringles de manoeuvre est équipée d'une crémaillère aux caractéristiques conformes à l'invention ;
  • . la figure 2 est une vue en coupe selon II-II de la figure 1.
The invention will be better understood on the basis of the following description accompanied by the drawings representing an exemplary embodiment.
  • . Figure 1 is a schematic view in partial section of a double direction cremone bolt, one of the operating rods is equipped with a rack with characteristics according to the invention;
  • . Figure 2 is a sectional view along II-II of Figure 1.

Tel que représenté, tout particulièrement, dans la figure 1 du dessin ci-joint, la présente invention est relative à une crémone pour porte, fenêtre ou analogue, sachant que cette invention concerne, par ailleurs, les crémones-serrures permettant également le verrouillage au moyen d'un élément à clé. Toutefois de manière à ne pas alourdir le style de la description qui va suivre et en faciliter, par ailleurs, la compréhension, il ne sera fait état que d'une crémone.As shown, in particular, in FIG. 1 of the attached drawing, the present invention relates to a cremone bolt for a door, window or the like, knowing that this invention also relates to the cremone bolts which also allow locking to the by means of a key element. However so as not to weigh down the style of the description which will follow and facilitate, moreover, understanding, it will only be reported a lever.

Dans tous les cas, une telle crémone 1 (ou crémone-serrure), comporte un mécanisme de commande 2 dont une au moins de ses fonctions consiste à assurer l'entraînement d'au moins une tringle de manoeuvre 3, lorsque ladite crémone 1 est monodirectionnelle, ou deux tringles de manoeuvre 3, 4 s'étendant, respectivement, au-dessus et en-dessous du boîtier 5, renfermant ledit mécanisme de commande 2, et venant se déplacer dans des directions opposées. Il s'agit, dans ce dernier cas de figure, plus particulièrement représenté dans le dessin, d'une crémone à double direction.In all cases, such a cremone bolt 1 (or cremone bolt) includes a control mechanism 2 of which at least one of its functions consists in ensuring the drive of at least one operating rod 3, when said cremone bolt 1 is monodirectional, or two operating rods 3, 4 extending, respectively, above and below the housing 5, enclosing said control mechanism 2, and coming to move in opposite directions. In the latter case, more particularly represented in the drawing, it is a double-direction cremone bolt.

Cet entraînement de la ou des tringles de manoeuvre 3, 4 s'effectue au moyen d'au moins une roue dentée 6 venant s'engréner sur une crémaillère 7, 8 équipant, soit directement la ou les tringles de manoeuvre 3, 4, tel que représenté dans la figure 1, soit un ou des chevalets intermédiaires reliés à ces tringles de manoeuvre 3, 4.This drive of the operating rod or rods 3, 4 is carried out by means of at least one toothed wheel 6 which engages on a rack 7, 8 equipping, either directly the operating rod or rods 3, 4, such as shown in FIG. 1, either one or more intermediate trestles connected to these operating rods 3, 4.

Dans le cas du mode de réalisation plus particulièrement représenté dans la figure 1, il s'agit de la même roue dentée 6 qui transmet le mouvement dans des directions opposées, à chacune des tringles de manoeuvre 3, 4. De plus, cette roue dentée 6 constitue le fouillot dont le moyeu 9 comporte une ouverture 10 susceptible d'accueillir le carré de manoeuvre d'une poignée de commande accessible à l'usager. Là encore, la présente invention n'est nullement limitée à une telle conception puisque l'on peut parfaitement imaginer un entraînement au moyen d'une roue dentée qui ne constitue pas nécessairement, le fouillot. De même, chacune des tringles de manoeuvre 3, 4 dans le cadre d'une crémone bidirectionnelle peut être entraînée par des roues dentées distinctes.In the case of the embodiment more particularly shown in FIG. 1, it is the same toothed wheel 6 which transmits the movement in opposite directions, to each of the operating rods 3, 4. In addition, this toothed wheel 6 constitutes the follower, the hub 9 of which has an opening 10 capable of accommodating the operating square of a control handle accessible to the user. Again, the present invention is not limited to such a design since one can perfectly imagine a drive by means of a toothed wheel which does not necessarily constitute, the follower. Similarly, each of the operating rods 3, 4 in the context of a bidirectional cremone bolt can be driven by separate toothed wheels.

De plus, selon ce mode de réalisation représenté, cette roue dentée 6, et donc le fouillot, porte, sur son pourtour, dans son plan médian vertical 12, un pêne de verrouillage 13 qui, en position verrouillée de la crémone 1, vient se présenter saillant par rapport à la face externe 14 d'une têtière 15 à l'arrière de laquelle s'étendent la ou les tringles de manoeuvre 3, 4. A noter que cette têtière 15 comporte, à cet effet, une ouverture 16 servant au passage de ce pêne de verrouillage 13.In addition, according to this embodiment shown, this toothed wheel 6, and therefore the follower, carries, on its periphery, in its vertical median plane 12, a locking bolt 13 which, in the locked position of the cremone bolt 1, comes present projecting with respect to the external face 14 of a headrest 15 at the rear of which extend the operating rod or rods 3, 4. Note that this headrest 15 comprises, for this purpose, an opening 16 used for passage of this locking bolt 13.

Dans ce même but, une telle ouverture 17 a également été ménagée dans la tringle de manoeuvre 3 venant s'interposer entre la roue dentée et donc le fouillot 6 et ladite têtière 15. Il est évident, dans ces conditions, que cette tringle de manoeuvre 3 en raison de cette ouverture 17, est considérablement fragilisée, à un endroit où doit, finalement, s'effectuer l'entraînement au moyen de ladite roue dentée 6.For this same purpose, such an opening 17 has also been made in the operating rod 3 coming to be interposed between the toothed wheel and therefore the follower 6 and said headrest 15. It is obvious, under these conditions, that this operating rod 3 due to this opening 17, is considerably weakened, at a place where the drive must ultimately be carried out by means of said toothed wheel 6.

Aussi, selon l'invention, la crémaillère 7 est réalisée par déformation, plus particulièrement, par emboutissage, du plat métallique 18 concevant ladite tringle de manoeuvre 3 de manière à conférer à ce plat métallique 18 une ondulation 20 sur les bossages 21 de laquelle est à même de s'engréner la denture 22 de la roue dentée 6.Also, according to the invention, the rack 7 is produced by deformation, more particularly, by stamping, of the metal plate 18 designing said operating rod 3 so as to give this metal plate 18 a corrugation 20 on the bosses 21 of which is able to mesh the toothing 22 of the toothed wheel 6.

En définitive, cette crémaillère 7, sous forme d'une ondulation 20 obtenue par déformation de la tringle de manoeuvre 3, vient renforcer cette dernière à un endroit où elle est d'ores et déjà fragilisée et lui confère, de ce fait, la tenue mécanique requise dans ce type de ferrure de verrouillage.Ultimately, this rack 7, in the form of a corrugation 20 obtained by deformation of the operating rod 3, comes to reinforce the latter at a place where it is already weakened and therefore gives it the strength mechanical required in this type of locking fitting.

Il convient de noter que pour obtenir une répartition uniforme des efforts sur le fouillot et donc la roue dentée 6, celle-ci comporte une denture 22 de part et d'autre du pêne de verrouillage 13 à même de coopérer avec la crémaillère 7 ménagée au niveau de chacune des branches 7A, 7B correspondant au plat métallique 18 et délimitant, de part et d'autre, l'ouverture 17.It should be noted that to obtain a uniform distribution of the forces on the follower and therefore the toothed wheel 6, the latter has a toothing 22 on either side of the locking bolt 13 capable of cooperating with the rack 7 formed at each of the branches 7A, 7B corresponding to the metal plate 18 and delimiting, on either side other, opening 17.

Il est encore représenté sur cette figure 1 un entraînement plus conventionnel de la seconde tringle de manoeuvre 4 venant se déplacer en sens inverse par rapport à la tringle de manoeuvre 3. Plus précisément, dans ce cas de figure, l'extrémité 23 de cette tringle de manoeuvre 4 n'étant pas fragilisée par la présence d'une ouverture quelconque, la crémaillère 8 qui l'équipe se présente sous forme d'une succession d'ouvertures 24 aménagées dans le plat métallique constituant cette tringle de manoeuvre 4, ces ouvertures 24 délimitant des barreaux transversaux 25 sur lesquels est à même de s'engréner une autre denture 26 équipant le fouillot que constitue la roue dentée 6. Plus particulièrement la denture 26 est aménagée sur cette roue dentée 6 constituant le fouillot, sensiblement, de manière diamétralement opposée à la denture 22 coopérant avec la crémaillère 7 de l'autre tringle de manoeuvre 3. Par ailleurs, cette denture 26 se situe, sensiblement, dans le plan médian vertical 12, de la roue dentée 6.There is also shown in this FIG. 1 a more conventional drive for the second operating rod 4 coming to move in the opposite direction relative to the operating rod 3. More precisely, in this case, the end 23 of this rod of maneuver 4 not being weakened by the presence of any opening, the rack 8 which the team is in the form of a succession of openings 24 arranged in the metal plate constituting this operating rod 4, these openings 24 delimiting transverse bars 25 on which is capable of meshing another toothing 26 fitted to the follower that constitutes the toothed wheel 6. More particularly the toothing 26 is arranged on this toothed wheel 6 constituting the follower, substantially, diametrically opposite to the toothing 22 cooperating with the rack 7 of the other operating rod 3. Furthermore, this toothing 26 is located, substantially, d in the vertical median plane 12, of the toothed wheel 6.

Il est évident que l'on aurait pu concevoir sur cette seconde tringle de manoeuvre 4 une crémaillère sous forme d'une déformation du plat métallique qui la constitue et, donc, de manière similaire à la crémaillère 7 correspondant à la tringle de manoeuvre 3. En outre, tel que déjà précisé plus haut, au lieu d'équiper directement des tringles de manoeuvre de crémaillères 7, 8, celles-ci peuvent être aménagées d'une manière similaire sur des chevalets destinés à être reliés à de telles tringles de manoeuvre 3. En outre, tel que déjà précisé plus haut, au lieu d'équiper directement des tringles de manoeuvre de crémaillères 7, 8, celles-ci peuvent être aménagées d'une manière similaire sur des chevalets destinés à être reliés à de telles tringles de manoeuvre 3, 4.It is obvious that one could have designed on this second operating rod 4 a rack in the form of a deformation of the metal plate which constitutes it and, therefore, similarly to the rack 7 corresponding to the operating rod 3. In addition, as already specified above, instead of directly equipping rods with racks 7, 8, these can be arranged in a similar manner on trestles intended to be connected to such rods 3. In addition, as already specified above, instead of directly fitting rods for operating racks 7, 8, these can be arranged in a similar manner on easels intended to be connected to such operating rods 3, 4.

Les avantages obtenus grâce à cette invention sont, évidemment, une consolidation dans tous les cas de figure, de la ou des tringles de manoeuvre ou encore des chevalets au travers de la crémaillère qui les équipe et qui, jusqu'alors, ne conduisait qu'à leur fragilisation.The advantages obtained thanks to this invention are, of course, a consolidation in all cases, of the operating rod or rods or of the easels through the rack which equips them and which, until then, only drove to their embrittlement.
