Description
L'invention a pour objet un verrou automatique de fermeture pour volet roulant composé de lames tubulaires. The subject of the invention is an automatic closing lock for a rolling shutter composed of tubular blades.
L'invention est un perfectionnement apporté au verrou déjà décrit dans la demande de brevet principal déposée le 16 juin 1983 sous le n0 83 10196. L'état de la technique est défini dans la description de ce brevet principal. The invention is an improvement made to the lock already described in the main patent application filed on June 16, 1983 under the number 83 10196. The state of the art is defined in the description of this main patent.
Le verrou décrit dans le brevet principal ci-dessus cité ne peut être mis en place que sur un volet spécialement conçu à cet effet. Le pêne à bascule 9 doit être mis en place et fixé sur la première lame du volet qui doit elle-même être préparée et comporter des moyens de logement et de fixation. La sangle d'attache 14, qui est fixée au pêne à bascule 9, doit être fixée à l'axe d'enroulement. C'est en fait une sangle qui fait office de sangle de commande de l'action du verrou qui s'ajoute à la sangle d'attache qui est fixée à l'agrafe de la première lame du volet et qui est ainsi reliée à toute la chaîne d'agrafes. Il est donc nécessaire de régler la longueur des sangles de commande de l'action du verrou par rapport à celle des sangles d'attache. The lock described in the aforementioned main patent can only be installed on a flap specially designed for this purpose. The rocker bolt 9 must be put in place and fixed on the first blade of the shutter which must itself be prepared and include means of housing and fixing. The tether strap 14, which is fixed to the rocker bolt 9, must be fixed to the winding axis. It is in fact a strap which acts as a strap for controlling the action of the bolt which is added to the fastening strap which is fixed to the clip of the first blade of the shutter and which is thus connected to any the chain of staples. It is therefore necessary to adjust the length of the straps for controlling the action of the lock relative to that of the attachment straps.
Le perfectionnement selon l'invention ne nécessite pas la mise en place de sangles spécifiques. Le verrou automatique de fermeture pour volet roulant utilise les sangles d'attache déjà en place qui vont être utilisées sans aucune modification, à la fois comme sangles d'attache et comme sangles de commande de l'action du verrou. Ainsi, les verrous selon l'invention pourront en plus être mis en place sur des volets roulants actuellement en service et ce dans un temps de pose minimum. The improvement according to the invention does not require the installation of specific straps. The automatic closing latch for rolling shutters uses the fastening straps already in place which will be used without any modification, both as fastening straps and as straps for controlling the action of the lock. Thus, the locks according to the invention may in addition be placed on rolling shutters currently in service and this in a minimum installation time.
A cet effet, le verrou selon l'invention est composé d'un pêne à bascule disposé sur la première lame, ledit pêne est actionné par la sangle d'attache qui fait donc office de sangle de commande et qui est reliée d'une part à l'axe d'enroulement du volet et d'autre part à l'agrafe de la première lame du volet. Un doigt de commande, en contact avec la sangle d'attache et de commande, actionne le pêne à bascule dont l'axe de rotation comporte un ressort en épingle. Par une fenêtre ménagée sur la tranche supérieure de la première lame du volet, l'embase du pêne est engagée dans ladite lame qui fait alors office de logement. Par l'extrémité de la lame, un moyen de blocage vient maintenir et bloquer l'embase du pêne dans son logement.Ce moyen de blocage est composé de deux pièces qui s'enfilent par l'extrémité de la lame tubulaire et qui, par leur profilé, viennent bloquer l'embase du pêne dans son logement. Ces pièces de blocage ont une extrémité qui comporte des épaulements qui viennent se bloquer de part et d'autre des côtés de l'embase du pêne et dont l'autre extrémité se termine par un épaulement qui vient se bloquer contre l'extrémité de la première lame. To this end, the lock according to the invention is composed of a rocking bolt disposed on the first blade, said bolt is actuated by the fastening strap which therefore acts as a control strap and which is connected on the one hand to the winding axis of the shutter and on the other hand to the clip of the first blade of the shutter. A control finger, in contact with the attachment and control strap, activates the rocker bolt, the axis of rotation of which comprises a pin spring. Through a window provided on the upper edge of the first blade of the shutter, the bolt base is engaged in said blade which then acts as a housing. By the end of the blade, a blocking means holds and blocks the bolt base in its housing. This blocking means is composed of two parts which are threaded through the end of the tubular blade and which, by their profile, block the bolt base in its housing. These blocking parts have one end which has shoulders which come to block on either side of the sides of the bolt base and the other end of which ends in a shoulder which comes to block against the end of the first blade.
Le pêne selon l'invention est composé de deux parties articulées entre elles. A une extrémité de ses côtés en largeur, chaque partie comporte des éléments faisant office de broches, qui permettent, en associant les deux parties du pêne de former une charnière comprenant, monté autour de son axe de rotation, un ressort en épingle. A l'autre extrémité du pêne proprement dit, un épaulement en biseau permet au pêne de venir s'accrocher sur la gâche. Dans cet épaulement une rainure en olive permet de mettre en place un axe qui fait office de doigt de commande. C'est ce doigt de commande qui sera en contact avec le brin de la sangle d'attache et de commande. De préférence, cet axe de commande est gainé par un manchon en caoutchouc ou plastique. Ce gainage évite au pêne de marquer les lames lorsque le volet est enroulé sur l'axe. The bolt according to the invention is composed of two parts hinged together. At one end of its width sides, each part has elements acting as pins, which allow, by associating the two parts of the bolt to form a hinge comprising, mounted around its axis of rotation, a pin spring. At the other end of the bolt itself, a beveled shoulder allows the bolt to hang on the strike. In this shoulder an olive groove makes it possible to set up an axis which acts as a control finger. It is this control finger which will be in contact with the strand of the attachment and control strap. Preferably, this control axis is sheathed by a rubber or plastic sleeve. This sheathing prevents the bolt from marking the blades when the shutter is wound on the axis.
Le profilé de chaque partie du pêne est identique. The profile of each part of the bolt is identical.
Il comporte à une extrémité un épaulement arrondi et à l'autre extrémité un épaulement en biseau. Chaque épaulement comporte une rainure en olive. Pour faire office de broche, ce profilé est usiné au niveau de l'épaulement en biseau s'il s'agit de la partie servant d'embase du pêne logée dans la lame et il est usiné au niveau de l'épaulement arrondi s'il s'agit de la partie faisant office de pêne à bascule. It has at one end a rounded shoulder and at the other end a beveled shoulder. Each shoulder has an olive groove. To act as a spindle, this profile is machined at the beveled shoulder if it is the part serving as a base for the bolt housed in the blade and it is machined at the rounded shoulder s' this is the part that acts as a rocking bolt.
Les dessins ci-joints donnés à titre d'exemple indicatif et non limitatif permettront aisément de comprendre l'invention. Ils représentent un mode de réalisation préféré selon l'invention. The attached drawings given by way of indicative and non-limiting example will easily make it possible to understand the invention. They represent a preferred embodiment according to the invention.
La figure 1 est une vue en perspective du verrou mis en place, le brin de la sangle d'attache et de commande est tendu. Figure 1 is a perspective view of the lock in place, the strand of the attachment and control strap is stretched.
La figure 2 est une vue en perspective du verrou mis en place, le brin de la sangle d'attache et de commande est mou, le pêne du verrou est verrouillé sur la gâche. Figure 2 is a perspective view of the lock in place, the strand of the attachment and control strap is soft, the bolt of the lock is locked on the strike.
La figure 3 est une vue en perspective éclatée du verrou mis en place. Figure 3 is an exploded perspective view of the lock in place.
Le verrou selon l'invention est composé d'un pêne à bascule 18 disposé sur la première lame 19 du volet. Ledit pêne à bascule 18 est actionné par le brin d'une sangle d'attache et de commande 21 qui est relié par une extrémité 22 à l'axe d'enroulement (non représenté sur les figures), et par son autre extrémité 23, à la première agrafe 24. Le brin de la sangle d'attache et de commande 21 agit sur un doigt de commande 25 qui est fixé sur la partie basculante 26 du pêne 18. The lock according to the invention is composed of a rocking bolt 18 disposed on the first blade 19 of the shutter. Said rocker bolt 18 is actuated by the strand of an attachment and control strap 21 which is connected by one end 22 to the winding axis (not shown in the figures), and by its other end 23, to the first clip 24. The strand of the attachment and control strap 21 acts on a control finger 25 which is fixed to the tilting part 26 of the bolt 18.
L'autre partie 27 du pêne fait office d'embase et vient se loger dans la lame 19 par une fenêtre 28. The other part 27 of the bolt acts as a base and is received in the blade 19 by a window 28.
Un moyen de blocage 29 du pêne 18 dans la lame 19 est engagé par une des extrémité 30 de la lame tubulaire 19 pour venir bloquer 1'embase du pêne 27 dans son logement 28. A locking means 29 for the bolt 18 in the blade 19 is engaged by one of the ends 30 of the tubular blade 19 in order to block the base of the bolt 27 in its housing 28.
Ce moyen de blocage 29 est composé de deux pièces 31 et 32. Ces deux pièces 31 et 32 s'enfilent par l'extrémité 30 de la lame tubulaire 19, et viennent d'une part bloquer, par les épaulements 33 et 34, la partie 27 du pêne qui fait office d'embase, et d'autre part buter, par leur épaulement 35 ou 36, contre les bords de l'extrémité 30 de la lame tubulaire 19. Ces pièces de blocage 31 et 32 peuvent, une fois mises en place, être verrouillées par des emboutis effectués sur la lame 19, ces emboutis enfonçant légèrement la lame 19 dans les trous 46 desdites pièces de blocage 31 et 32. This locking means 29 is composed of two parts 31 and 32. These two parts 31 and 32 thread through the end 30 of the tubular strip 19, and come on the one hand to block, by the shoulders 33 and 34, the part 27 of the bolt which acts as a base, and on the other hand abut, by their shoulder 35 or 36, against the edges of the end 30 of the tubular blade 19. These locking parts 31 and 32 can, once put in place, be locked by stampings made on the blade 19, these stampings slightly pushing the blade 19 into the holes 46 of said locking pieces 31 and 32.
Le pêne 18 selon l'invention est composé de deux parties 26 et 27. The bolt 18 according to the invention is composed of two parts 26 and 27.
Chaque partie 26 ou 27 est un élément rectangulaire. A l'extrémité de ses côtés en largeur, cette partie comporte des éléments faisant office de broches 37 qui permettent, en associant les deux parties du pêne 18, de former une charnière comprenant, monté autour de son axe 38 de rotation, un ressort en épingle 39. A l'autre extrémité, un épaulement en biseau 40 permet au pêne de venir s'accrocher sur la gâche ; dans cet épaulement, une rainure en olive 41 permet de mettre en place un axe 42 qui fait office de doigt de commande 25. C'est ce doigt de commande 25 qui sera en contact avec le brin de la sangle d'attache et de commande 21. De préférence, cet axe de commande 42 est gainé par un manchon en caoutchouc ou plastique 43. Ce gainage évite au doigt de commande de couper la sangle 21 et de marquer les lames lorsque le volet est enroulé sur son axe.Each part 26 or 27 is a rectangular element. At the end of its widthwise sides, this part comprises elements acting as pins 37 which allow, by associating the two parts of the bolt 18, to form a hinge comprising, mounted around its axis 38 of rotation, a spring in pin 39. At the other end, a beveled shoulder 40 allows the bolt to hang on the strike; in this shoulder, an olive groove 41 makes it possible to set up a pin 42 which acts as a control finger 25. It is this control finger 25 which will be in contact with the strand of the attachment and control strap 21. Preferably, this control axis 42 is sheathed by a rubber or plastic sleeve 43. This sheathing prevents the control finger from cutting the strap 21 and marking the blades when the shutter is wound on its axis.
Le profilé de chaque partie 26 ou 27 du pêne est identique, mais il est usiné de façon différente selon qu'une partie 27 est 1'embase du pêne 18, logé dans la lame 19, ou que l'autre partie 26 est le pêne à bascule proprement dit. The profile of each part 26 or 27 of the bolt is identical, but it is machined differently depending on whether a part 27 is the base of the bolt 18, housed in the blade 19, or whether the other part 26 is the bolt toggle proper.
La partie 27 comporte, à une extrémité, un épaulement arrondi 44 qui comporte une rainure en olive 45, et à l'autre extrémité un épaulement en biseau 40 qui a été usiné pour faire office de broche 37. The part 27 has, at one end, a rounded shoulder 44 which has an olive groove 45, and at the other end a bevel shoulder 40 which has been machined to act as a pin 37.
Comme on peut le constater, le verrou selon l'invention peut être mis en place sur des volets roulants à lames tubulaires existants et ce dans un temps de montage rapide. Il n'y a pas de sangles spécifiques puisque l'on utilise les sangles d'attache déjà en place. Il suffit de mettre en place sur la coulisse de guidage 5 une platine 6, cette platine 6 reçoit la gâche 47. As can be seen, the lock according to the invention can be put in place on rolling shutters with existing tubular blades and this in a rapid assembly time. There are no specific straps since we use the tie straps already in place. It suffices to put a plate 6 on the guide slide 5, this plate 6 receives the keeper 47.
Lorsque le brin de la sangle 21 est tendu, la partie 26 du pêne à bascule est maintenue relevée par le doigt de commande 25 qui est en contact avec ledit brin. Dès que le brin de la sangle 21 est mou, c'esta-dire lorsque le volet est baissé, la partie 26 du pêne 18 bascule sous l'effet du ressort à épingle 39 autour de l'axe 38 de sa charnière et vient s'engager dans la gâche 47, verrouillant ainsi le volet. When the strand of the strap 21 is tensioned, the part 26 of the rocking bolt is kept raised by the control finger 25 which is in contact with said strand. As soon as the strand of the strap 21 is soft, that is to say when the flap is lowered, the part 26 of the bolt 18 rocks under the effect of the pin spring 39 around the axis 38 of its hinge and comes s 'engage in the strike 47, thus locking the shutter.
