Description

L'invention a trait à une crémone à têtière à double direction comprenant, dans un boîtier solidaire de la têtière, un mécanisme comportant un fouillot commandant directement l'extrémité d'une première tringle de verrouillage, coulissant le long de la face interne de la têtière par l'intermédiaire d'une pièce de liaison pourvue d'un téton coopérant avec une lumière réalisée dans le corps du fouillot et indirectement, l'extrémité d'une seconde tringle de verrouillage, disposée contre le fond du boîtier, par l'intermédiaire d'un élément inverseur, les deux tringles de verrouillage se déplaçant en sens contraire étant disposées dans un même alignement et à plat contre la face interne de la têtière.The invention relates to a cremone bolt with two-way headrest comprising, in a housing integral with the headrest, a mechanism comprising a nut directly controlling the end of a first locking rod, sliding along the internal face of the headrest by means of a connecting piece provided with a stud cooperating with a light produced in the body of the follower and indirectly, the end of a second locking rod, disposed against the bottom of the housing, by the through a reversing element, the two locking rods moving in opposite directions being arranged in the same alignment and flat against the internal face of the headrest.

Pour la mise en place d'une crémone à têtière à double direction, on réalise dans le chant du profilé de l'ouvrant d'une fenêtre, porte-fenêtre ou analogue une entaille dont la profondeur est fonction de la largeur du boîtier, ladite largeur étant déterminée par la distance de l'axe du fouillot par rapport à la face externe de la têtière.For the installation of a cremone bolt with a double direction headrest, a cut is made in the edge profile of the opening of a window, French window or the like, the depth of which depends on the width of the housing, said width being determined by the distance from the axis of the follower from the external face of the headrest.

Du fait que cette distance est variable, il est nécessaire de varier également la profondeur de l'entaillage pour le logement du boîtier. Ces variations de profondeur du logement obligent le fabricant de fenêtres, porte-fenêtres ou analogues, d'une part, de régler sa machine à entailler à la profondeur du logement nécessaire au boîtier, et, d'autre part, de prévoir un profilé plus large pour éviter l'affaiblissement du montant de l'ouvrant de la fenêtre, porte-fenêtre ou analogue par un entaillage profond.Because this distance is variable, it is necessary to also vary the depth of the notch for the housing of the housing. These variations in the depth of the housing oblige the manufacturer of windows, French windows or the like, on the one hand, to adjust his notching machine to the depth of the housing necessary for the housing, and, on the other hand, to provide a more profiled profile. wide to avoid weakening of the amount of the window sash, French window or the like by deep notching.

Pour remédier à cet inconvénient, on a conçu une crémone permettant de normaliser la profondeur de l'entaillage du logement pour le boîtier, cette profondeur étant la même malgré différentes distances entre l'axe du fouillot et la face externe de la têtière.To overcome this drawback, a cremone bolt has been designed to standardize the depth of the notching of the housing for the housing, this depth being the same despite different distances between the axis of the follower and the external face of the headrest.

Ainsi, on connaît déjà, par le document EP-A-0 229 582 considéré au titre de l'Article 54 (3) et (4) de la CBE, une crémone à têtière à double direction comprenant dans un boitier solidaire de la têtière, un mécanisme comportant un fouillot commandant directement l'extrémité d'une première tringle de verrouillage, coulissant le long de la face interne de la têtière par l'intermédiaire d'une pièce de liaison pourvue d'un téton coopérant avec une lumière réalisée dans le corps du fouillot et l'extrémité d'une seconde tringle de verrouillage, disposée contre le fond du boîtier, par l'intermédiaire d'un élément inverseur, les deux tringles de verrouillage se déplaçant en sens contraire étant disposées dans un même alignement et à plat contre la face interne de la têtière.Thus, we already know, from document EP-A-0 229 582 considered under Article 54 (3) and (4) of the EPC, a cremone bolt with a double-headed headrest comprising in a housing integral with the headrest , a mechanism comprising a follower directly controlling the end of a first locking rod, sliding along the internal face of the headrest by means of a connecting piece provided with a stud cooperating with a light produced in the body of the follower and the end of a second locking rod, disposed against the bottom of the housing, by means of an inverting element, the two locking rods moving in opposite directions being arranged in the same alignment and flat against the inner face of the headrest.

Cependant, pour satisfaire au but recherché, cette crémone présente plusieurs inconvénients. En effet, la pièce de liaison comporte un chant de guidage prenant appui contre l'arbre du fouillot. Du fait que cet arbre présente un faible diamètre pour réduire l'encombrement du mécanisme logé dans le boîtier, l'usure dudit arbre, suite aux frottements répétés par le chant de guidage de la pièce de liaison, est accélérée, ce qui diminue la fiabilité de la crémone.However, to meet the desired goal, this cremone bolt has several drawbacks. Indeed, the connecting piece includes a guide edge bearing against the shaft of the follower. Because this shaft has a small diameter to reduce the size of the mechanism housed in the housing, the wear of said shaft, following repeated friction by the guide song of the connecting piece, is accelerated, which reduces reliability cremone bolt.

Par ailleurs, l'extrémité de la seconde tringle de verrouillage comporte, en regard du fouillot, une lumière de dégagement. Il est certain que cette dernière affaiblit ladite extrémité de la seconde tringle de verrouillage surtout que la largeur de cette lumière de dégagement doit être plus large que l'épaisseur du fouillot pour éviter que ce dernier ne se coince dans la lumière de dégagement.Furthermore, the end of the second locking rod comprises, facing the follower, a release light. It is certain that the latter weakens said end of the second locking rod, especially that the width of this clearance light must be wider than the thickness of the nut to prevent the latter from getting stuck in the clearance light.

Il est alors prévu de remédier à ces inconvénients et de concevoir une crémone à têtière à double direction donnant satisfaction au souci de standardisation du boîtier et, par voie de conséquence, de la standardisation de la profondeur d'entaillage dans le montant de l'ouvrant tout en augmentant la durée de vie de ladite crémone. La crémone à têtière à double direction comprend dans un boîtier solidaire de la têtière, un mécanisme comportant un fouillot commandant directement l'extrémité d'une première tringle de verrouillage, coulissant le long de la face interne de la têtière par l'intermédiaire d'une pièce de liaison pourvue d'un téton coopérant avec une lumière réalisée dans le corps du fouillot et, indirectement, l'extrémité d'une seconde tringle de verrouillage, disposée contre le fond du boîtier par l'intermédiaire d'un élément inverseur, les deux tringles de verrouillage se déplaçant en sens contraire étant disposées dans un même alignement et à plat contre la face interne de la têtière et dont le fouillot comporte un arbre pourvu d'un renfort concentrique venant en appui sur le chant de guidage de la pièce de liaison et la face interne de l'extrémité de la seconde tringle de verrouillage.It is then planned to remedy these drawbacks and to design a cremone bolt with double direction giving satisfaction with the concern of standardization of the case and, consequently, of standardization of the depth of notching in the amount of the opening while increasing the service life of said cremone bolt. The double direction headrest lever comprises in a housing integral with the headrest, a mechanism comprising a nut directly controlling the end of a first locking rod, sliding along the internal face of the headrest by means of a connecting piece provided with a stud cooperating with a light produced in the body of the follower and, indirectly, the end of a second locking rod, disposed against the bottom of the housing by means of an reversing element, the two locking rods moving in opposite directions being arranged in the same alignment and flat against the internal face of the headrest and whose follower comprises a shaft provided with a concentric reinforcement bearing on the guide song of the part of connection and the internal face of the end of the second locking rod.

Selon une conception particulière de l'invention, le renfort concentrique est une bague d'usure enfilée sur l'arbre et solidaire en rotation de celui-ci.According to a particular design of the invention, the concentric reinforcement is a wear ring threaded on the shaft and integral in rotation with the latter.

Un des avantages obtenus grâce à cette invention consiste essentiellement en un bon équilibre de masse conféré au fouillot et une répartition symétrique des efforts engendrés au verrouillage ou au déverrouillage des deux tringles de la crémone.One of the advantages obtained thanks to this invention consists essentially in a good balance of mass conferred on the follower and a symmetrical distribution of the forces generated when locking or unlocking the two rods of the lever.

Selon un autre développement de la crémone selon l'invention, l'extrémité de la seconde tringle de verrouillage comporte sur sa face interne un évidement dont la longueur est au moins égale à la somme de la longueur du talon du corps du fouillot et de la longueur de la course de la seconde tringle de verrouillage.According to another development of the cremone bolt according to the invention, the end of the second locking rod has on its internal face a recess the length of which is at least equal to the sum of the length of the heel of the body of the follower and the length of travel of the second locking rod.

Selon une autre réalisation particulière de la crémone selon l'invention, l'extrémité de la seconde tringle de verrouillage comporte un tronçon estampé présentant un épaulement faisant saillie par rapport à la face externe de l'extrémité de la seconde tringle de verrouillage et dirigé vers le fond du boîtier, la longueur de cet épaulement étant au moins égale à la somme de la longueur du talon du corps du fouillot et de la longueur de la course de la seconde tringle de verrouillage. Selon une autre particularité de la crémone selon l'invention, le fond du boîtier comporte une lumière dans laquelle coulisse l'épaulement du tronçon estampé de l'extrémité de la seconde tringle de verrouillage.According to another particular embodiment of the cremone bolt according to the invention, the end of the second locking rod comprises a stamped section having a shoulder projecting with respect to the external face of the end of the second locking rod and directed towards the bottom of the housing, the length of this shoulder being at least equal to the sum of the length of the heel of the body of the follower and the length of the stroke of the second locking rod. According to another feature of the cremone bolt according to the invention, the bottom of the housing includes a slot in which slides the shoulder of the stamped section from the end of the second locking rod.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of drawings representing only one embodiment.

La figure 1 représente, en vue en élévation et en coupe, la crémone à têtière à double direction conforme à l'invention, la crémone étant en position de déverrouillage.Figure 1 shows, in elevation and in section, the cremone bolt with double direction in accordance with the invention, the cremone bolt being in the unlocked position.

On se réfère à la figure unique.We refer to the single figure.

La crémone 1 comporte un boîtier 2 logé dans un entaillage pratiqué dans une rainure réalisée dans le chant du montant d'un ouvrant de fenêtres, porte-fenêtres et analogues. Cette rainure est obturée par une têtière 3 d'une crémone à double direction et solidaire dudit boîtier. Le long de la face interne 4 de la têtière 3 coulissent deux tringles de verrouillage 5, 6 se déplaçant en sens contraire et dont les extrémités 7, 8 pénètrent dans le boîtier 2. Ces deux tringles de verrouillage 5, 6 sont actionnées par un fouillot 9 comportant un corps 10 présentant, lorsque la crémone est en position de verrouillage, une partie saillante 11 traversant une lumière 12 réalisée dans la têtière 3 et constituant un pêne battant, un arbre 13, dans lequel est réalisé un trou carré 14 pour l'introduction du carré de manoeuvre d'une poignée, et un talon 15.The cremone bolt 1 comprises a housing 2 housed in a notch formed in a groove made in the edge of the upright of a window opening, French windows and the like. This groove is closed by a headrest 3 of a double direction lever and secured to said housing. Along the internal face 4 of the headrest 3 slide two locking rods 5, 6 moving in opposite directions and the ends 7, 8 of which penetrate into the housing 2. These two locking rods 5, 6 are actuated by a follower 9 comprising a body 10 having, when the cremone bolt is in the locked position, a projecting part 11 passing through a lumen 12 produced in the headrest 3 and constituting a beating bolt, a shaft 13, in which a square hole 14 is made for the introduction of the operating square of a handle, and a heel 15.

Le fouillot 9 commande directement l'extrémité 7 de la première tringle de verrouillage 5 par l'intermédiaire d'une pièce de liaison 16. Cette pièce de liaison 16 présente un chant de guidage coulissant sur le pourtour de l'arbre 13 du fouillot 9 assurant ainsi le guidage de cette pièce de liaison 16 et sa coopération avec l'extrémité 7 de la première tringle de verrouillage 5. La pièce de liaison 16 comporte à l'une de ses extrémités 17 un téton 18 coopérant avec une lumière 19 réalisée dans le corps 10 du fouillot 9 et à l'autre extrémité 20 un téton de commande 21 s'engageant dans un orifice 22 pratiqué dans l'extrémité 7 de la première tringle de verrouillage 5.The follower 9 directly controls the end 7 of the first locking rod 5 by means of a connecting piece 16. This connecting piece 16 has a sliding guide edge around the periphery of the shaft 13 of the follower 9 thus ensuring the guiding of this connecting piece 16 and its cooperation with the end 7 of the first locking rod 5. The connecting piece 16 comprises at one of its ends 17 a stud 18 cooperating with a light 19 produced in the body 10 of the follower 9 and at the other end 20 a control stud 21 engaging in an orifice 22 formed in the end 7 of the first locking rod 5.

Cette dernière comporte une denture 23 entraînant un élément inverseur 24 constitué par un pignon denté pouvant pivoter autour d'un axe 25 solidaire des parois latérales 26 du boîtier 2. Cet élément inverseur 24 coopère avec une denture 27 de l'extrémité 8 de la seconde tringle de verrouillage 6, cette extrémité 8 étant reliée à la seconde tringle de verrouillage 6 par une pièce de renvoi 28.The latter has a toothing 23 driving an reversing element 24 constituted by a toothed pinion which can pivot about an axis 25 integral with the side walls 26 of the housing 2. This reversing element 24 cooperates with a toothing 27 of the end 8 of the second locking rod 6, this end 8 being connected to the second locking rod 6 by a return piece 28.

Les deux tringles de verrouillage 5, 6 sont disposées dans un même alignement alors que l'extrémité 7 de la première tringle de verrouillage 5 se déplace le long de la face interne 4 de la têtière 3 et l'extrémité 8 de la seconde tringle de verrouillage 6 se déplace le long de la face interne 29 du fond 30 du boîtier 2.The two locking rods 5, 6 are arranged in the same alignment while the end 7 of the first locking rod 5 moves along the internal face 4 of the headrest 3 and the end 8 of the second rod lock 6 moves along the internal face 29 of the bottom 30 of the housing 2.

Conformément à l'invention, l'arbre 13 du fouillot 9 est pourvu d'un renfort concentrique 31. Selon un premier mode de réalisation, le renfort concentrique 31 fait partie intégrante de l'arbre 13. Le pourtour extérieur 32 du renfort concentrique 31 est à fleur avec le chant 33 du talon 15 et prend appui également sur la face interne de l'extrémité 8 de la seconde tringle de verrouillage 6.According to the invention, the shaft 13 of the follower 9 is provided with a concentric reinforcement 31. According to a first embodiment, the concentric reinforcement 31 is an integral part of the shaft 13. The outer periphery 32 of the concentric reinforcement 31 is flush with the edge 33 of the heel 15 and also bears on the internal face of the end 8 of the second locking rod 6.

Selon un autre mode de réalisation, le renfort concentrique est une bague d'usure enfilée sur l'arbre 13 et elle est solidaire en rotation de ce dernier, le pourtour extérieur de cette bague étant à fleur avec le chant 33 du talon 15 et prend appui également sur la face interne de l'extrémité 8 de la seconde tringle de verrouillage 6.According to another embodiment, the concentric reinforcement is a wear ring threaded on the shaft 13 and it is integral in rotation with the latter, the outer periphery of this ring being flush with the edge 33 of the heel 15 and takes also pressing on the internal face of the end 8 of the second locking rod 6.

Pour se conformer au but recherché, à savoir ramener la largeur du boîtier 2 à la dimension la plus faible de la profondeur de l'entaillage, il est nécessaire d'absorber la surépaisseur de l'arbre 13 du fouillot 9 résultant de l'épaisseur du renfort concentrique 31 ou de l'épaisseur de la bague d'usure.To comply with the desired goal, namely to reduce the width of the housing 2 to the smallest dimension of the depth of the notching, it is necessary to absorb the excess thickness of the shaft 13 of the follower 9 resulting from the thickness concentric reinforcement 31 or the thickness of the wear ring.

Selon un premier mode de réalisation, on réalise dans la face interne 34 de l'extrémité 8 de la seconde tringle de verrouillage 6 un évidement 35 dans lequel peut coulisser l'arbre 13 pourvu du renfort concentrique 31. La longueur 36 de cet évidement 35 est au moins égale à la somme de la longueur 37 du talon 15 du fouillot 9 et de la course 38 de la seconde tringle de verrouillage 6. Cependant, la surépaisseur de l'arbre 13 du fouillot 9 se fait au détriment de l'épaisseur de l'extrémité 8 de la seconde tringle de verrouillage 6. C'est pourquoi, on préconise un second mode de réalisation. Selon ce second mode de réalisation, l'extrémité 8 de la seconde tringle de verrouillage 6 comporte un tronçon estampé 39 dirigé vers le fond 30 du boîtier 2. Par suite de l'estampage, ladite extrémité 8 comporte, à hauteur du tronçon estampé 39, un épaulement 40 faisant saillie par rapport à la face externe 41 de l'extrémité 8 de la seconde tringle de verrouillage 6. La longueur de ce tronçon estampé est égale à la longueur de l'épaulement 40. A cet effet, on pratique dans le fond 30 du boîtier 2 une lumière 42 dont la longueur 43 est au moins égale à la somme de la longueur de l'épaulenent 40 du tronçon estampé 39 et de la course 38 de la seconde tringle de verrouillage 6.According to a first embodiment, a recess 35 in which the shaft 13 provided with the concentric reinforcement 31 can be made in the internal face 34 of the end 8 of the second locking rod 6. The length 36 of this recess 35 is at least equal to the sum of the length 37 of the heel 15 of the follower 9 and the stroke 38 of the second locking rod 6. However, the excess thickness of the shaft 13 of the follower 9 is at the expense of the thickness of the end 8 of the second locking rod 6. This is why a second embodiment is recommended. According to this second embodiment, the end 8 of the second locking rod 6 comprises a stamped section 39 directed towards the bottom 30 of the housing 2. Following the stamping, said end 8 comprises, at the height of the stamped section 39 , a shoulder 40 projecting from the outer face 41 of the end 8 of the second locking rod 6. The length of this stamped section is equal to the length of the shoulder 40. For this purpose, we practice in the bottom 30 of the housing 2 a light 42 whose length 43 is at least equal to the sum of the length of the shoulder 40 of the stamped section 39 and the stroke 38 of the second locking rod 6.

La hauteur 44 de l'épaulement 40 est égale ou légèrement inférieure à l'épaisseur 45 du fond 30 du boîtier 2, de sorte que la face externe 46 de l'épaulement 40 est à fleur ou légèrement en-deçà de la face externe 47 du fond 30 du boîtier 2.The height 44 of the shoulder 40 is equal to or slightly less than the thickness 45 of the bottom 30 of the housing 2, so that the external face 46 of the shoulder 40 is flush or slightly below the external face 47 from the bottom 30 of the housing 2.

La profondeur d'estampage 48 est égale à la hauteur 44, donc approximativement à l'épaisseur 45. De ce fait, on peut, par l'intermédiaire du renfort concentrique 31, augmenter le diamètre de l'arbre 13 du fouillot 9 d'une valeur approximativement égale à l'épaisseur 45 du fond 30 du boîtier 2 ou conférer à la bague d'usure une épaisseur approximativement égale à l'épaisseur 45 du fond 30 du boîtier 2. Ainsi, on assure également un guidage de l'extrémité 8 de la seconde tringle de verrouillage 6 par suite de la coopération de l'arbre 13 avec le fond du tronçon estampé 39 par l'intermédiaire du renfort concentrique 31 ou de la bague d'usure.The stamping depth 48 is equal to the height 44, therefore approximately to the thickness 45. As a result, it is possible, via the concentric reinforcement 31, to increase the diameter of the shaft 13 of the follower 9 of a value approximately equal to the thickness 45 of the bottom 30 of the housing 2 or give the wear ring a thickness approximately equal to the thickness 45 of the bottom 30 of the housing 2. Thus, the end is also guided 8 of the second locking rod 6 as a result of the cooperation of the shaft 13 with the bottom of the stamped section 39 via the concentric reinforcement 31 or the wear ring.
