DISPOSITIF ANTI-EFFRACTION POUR PORTE BASCULANTE
La présente invention concerne un dispositif anti-effraction pour porte basculante du type comportant - un panneau muni d'au moins un axe latéral mobile dans une coulisse de guidage et entraîné par une chaîne disposée le long de ladite coulisse, - un dispositif parachute intercalé entre une chaîne haute et une chaîne basse de ladite chaîne, ledit dispositif parachute étant monté à rotation autour dudit axe latéral et soumis à un couple de rappel fourni par un ressort, une première dent, dite dent basse, du dispositif parachute étant destinée à pénétrer positivement, sous l'action dudit couple de rappel, dans des trous de blocage prévus le long d'une première aile de la coulisse de guidage en cas de rupture de la chaîne.ANTI-BREAKTHROUGH DEVICE FOR A TILTING DOOR
The present invention relates to a burglar-proof device for an overhead door of the type comprising - a panel provided with at least one movable lateral axis in a guide slide and driven by a chain disposed along said slide, - a parachute device interposed between a high chain and a low chain of said chain, said parachute device being mounted for rotation about said lateral axis and subjected to a restoring torque provided by a spring, a first tooth, called low tooth, of the parachute device being intended to penetrate positively , under the action of said return torque, in blocking holes provided along a first wing of the guide slide in the event of chain failure.
L'invention trouve une application particulièrement avantageuse dans le domaine des portes basculantes à effacement vertical, motorisées ou manuelles. The invention finds a particularly advantageous application in the field of tilting doors with vertical erasure, motorized or manual.
Dans les portes basculantes du type rappelé dans le préambule, le dispositif parachute a pour fonction d'empêcher la chute du panneau desdites portes lors de la rupture d'une des chaînes de liaison avec son axe d'équilibrage situé en partie haute, au-dessus du panneau. Cette fonction est exigée par la norme NFP 25362 d'Octobre 1992 qui traite des fermetures pour baies libres et des portails. In overhead doors of the type recalled in the preamble, the function of the parachute device is to prevent the panel of said doors from falling during the breaking of one of the connecting chains with its balancing axis located in the upper part, above the panel. This function is required by standard NFP 25362 of October 1992 which deals with closings for free bays and gates.
Cependant, les portes basculantes à effacement vertical connues ne disposent d'aucun dispositif anti-effraction susceptible de s'opposer aux efforts de soulèvement appliqués de l'extérieur sur le panneau desdites portes. However, the known vertically erasing tilting doors do not have any anti-intrusion device capable of opposing the lifting forces applied from the outside to the panel of said doors.
Aussi, le problème technique à résoudre par l'objet de la présente invention est de doter les portes basculantes conformes au préambule d'un dispositif anti-effraction en doublant la fonction parachute dudit dispositif parachute d'une fonction anti-effraction. Also, the technical problem to be solved by the object of the present invention is to provide the tilting doors according to the preamble with an anti-intrusion device by doubling the parachute function of said parachute device with an anti-intrusion function.
La solution au problème technique posé consiste, selon la présente invention, en ce que ledit dispositif anti-effraction comprend, sur le dispositif parachute, une deuxième dent, dite dent haute, diamétralement opposée à ladite dent basse, destinée à pénétrer positivement, sous l'action du couple de rappel, dans une encoche de blocage prévue le long d'une deuxième aile de la coulisse de guidage, opposée à la première, lorsque, en cas d'effraction, la chaîne haute est détendue sous l'effet d'un effort vertical vers le haut. The solution to the technical problem posed consists, according to the present invention, in that said anti-break-in device comprises, on the parachute device, a second tooth, called a high tooth, diametrically opposite to said low tooth, intended to penetrate positively, under the action of the return torque, in a locking notch provided along a second wing of the guide slide, opposite the first, when, in the event of a break-in, the upper chain is relaxed under the effect of a vertical upward effort.
La description qui va suivre en regard des dessins annexés, donnés à titre d'exemples non limitatifs, fera bien comprendre en quoi consiste l'invention et comment elle peut être réalisée. The description which follows with reference to the appended drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be implemented.

La figure 2 est une vue de côté du dispositif de la figure 1 dans sa fonction parachute. Figure 2 is a side view of the device of Figure 1 in its parachute function.
La figure 3 est une vue de côté du dispositif de la figure 1 dans sa fonction anti-effraction. Figure 3 is a side view of the device of Figure 1 in its burglar-resistant function.
La figure 4 est une vue de dessus du dispositif de la figure 1. Figure 4 is a top view of the device of Figure 1.
La figure 5 est une vue de gauche du dispositif de la figure 1. Figure 5 is a left view of the device of Figure 1.
Les figures 1 à 5 montrent un dispositif anti-effraction pour une porte basculante comportant un panneau 100, visible en partie sur les figures 4 à 5, muni d'un axe 110 latéral mobile dans une coulisse 120 de guidage, un galet 140 de centrage assurant le maintien en position dudit axe 110. Le panneau 100 est entrainé dans son mouvement par une chaîne 130 disposée le long de la coulisse 120 de guidage. Figures 1 to 5 show an anti-intrusion device for a tilting door comprising a panel 100, partially visible in Figures 4 to 5, provided with a movable lateral axis 110 in a guide slide 120, a centering roller 140 ensuring the maintenance in position of said axis 110. The panel 100 is driven in its movement by a chain 130 disposed along the guide slide 120.
On peut voir sur les figures 1, 2 et 3 qu'un dispositif parachute 200 est intercalé entre une chaîne haute 131 et une chaîne basse 132 de la chaîne 130. Ce dispositif parachute est monté à rotation autour de l'axe 110 latéral du panneau 100 et est soumis à un couple de rappel fourni par un ressort 210 de torsion, une première dent 220, dite dent basse, du dispositif parachute étant destinée à pénétrer positivement, sous l'action dudit couple de rappel, dans des trous 221 de blocage prévus le long d'une première aile 121 de la coulisse 120 de guidage en cas de rupture de la chaîne 130. We can see in Figures 1, 2 and 3 that a parachute device 200 is interposed between a high chain 131 and a low chain 132 of the chain 130. This parachute device is rotatably mounted about the lateral axis 110 of the panel 100 and is subjected to a return torque supplied by a torsion spring 210, a first tooth 220, called the lower tooth, of the parachute device being intended to penetrate positively, under the action of said return torque, into blocking holes 221 provided along a first wing 121 of the guide slide 120 in the event of chain breakage 130.
En fonctionnement normal, tel que représenté sur la figure 1, le couple de rappel exercé par le ressort 210 de torsion est inférieur au couple appliqué au dispositif parachute par les chaînes haute 131 et basse 132. La dent basse 220 est en position repliée dans la coulisse 120 de guidage et l'axe latéral 110 du panneau 100 peut se déplacer librement en translation à l'intérieur de ladite coulisse. In normal operation, as shown in FIG. 1, the restoring torque exerted by the torsion spring 210 is less than the torque applied to the parachute device by the upper 131 and lower chains 132. The lower tooth 220 is in the folded position in the guide slide 120 and the lateral axis 110 of the panel 100 can move freely in translation inside said slide.
En cas de rupture de la chaîne 130, la figure 2 montre que, sous l'effet de son propre poids P, le panneau a tendance à se refermer violemment avec le danger que cela représente pour des personnes se trouvant sur la trajectoire de la chute du panneau. In the event of the chain 130 breaking, FIG. 2 shows that, under the effect of its own weight P, the panel tends to close violently with the danger that this represents for people on the path of the fall of the panel.
N'étant plus soumis au couple développé par les tensions des chaînes haute 131 et basse 132, le dispositif parachute 200 peut tourner autour de l'axe 110 sous l'action du ressort 210 de torsion dans le sens indiqué par la flèche F. La dent basse 220 est alors pousser contre ladite première aile 121 de la coulisse 120 de guidage jusqu'à ce que, au cours de la chute du panneau, ladite dent basse rencontre un trou 221 de blocage dans lequel elle pénètre positivement, -mobilisant ainsi le panneau dans son mouvement de descente.No longer subject to the torque developed by the tensions of the high 131 and low 132 chains, the parachute device 200 can rotate around the axis 110 under the action of the torsion spring 210 in the direction indicated by the arrow F. The low tooth 220 is then pushed against said first wing 121 of the guide slide 120 until, during the fall of the panel, said low tooth encounters a blocking hole 221 into which it penetrates positively, thus immobilizing the panel in its downward movement.
Sur la figure 3 est représenté un dispositif anti-effraction ayant pour fonction de s'opposer à un effort vertical vers le haut Pl appliqué en partie basse du panneau. Ce dispositif anti-effraction comprend, sur le dispositif parachute 200, une deuxième dent 230, dite dente haute, diamétralement opposée à la dent basse 220, destinée à pénétrer positivement dans une encoche 231 de blocage prévue le long d'une deuxième aile 122 de la coulisse 120 de guidage, opposée à la première. Dans la position normale de la figure 1, la dent haute 230, comme la dent basse 220, est dans une position repliée qui ne fait pas obstacle au mouvement du panneau. In Figure 3 is shown an anti-intrusion device having the function of opposing a vertical upward force Pl applied in the lower part of the panel. This burglar-proof device comprises, on the parachute device 200, a second tooth 230, called the upper tooth, diametrically opposite the lower tooth 220, intended to penetrate positively into a blocking notch 231 provided along a second wing 122 of the guide slide 120, opposite the first. In the normal position of FIG. 1, the high tooth 230, like the low tooth 220, is in a folded position which does not obstruct the movement of the panel.
Le fonctionnement du dispositif anti-effraction conforme à l'invention est illustré sur la figure 3. Si une personne tente de soulever la panneau par la base en appliquant un effort P' s'opposant au poids de la porte, la chaîne haute 131 à tendance à se détendre, du fait par exemple que l'axe de liaison de la porte est maintenu en rotation par effet de frein moteur. Le dispositif anti-effraction 200 peut alors pivoter autour de l'axe 110 dans le sens indiqué par la flèche F sous l'action du ressort 210. La dent haute 230 est donc amenée en appui forcé entre la deuxième aile 122 de la coulisse 120. Si, lors du mouvement du panneau vers le haut, la dent haute 230 arrive à la hauteur de l'encoche 231 de blocage, elle y pénètre positivement, empêchant ainsi le mouvement vers le haut de se poursuivre. The operation of the burglar-proof device according to the invention is illustrated in FIG. 3. If a person attempts to lift the panel by the base by applying a force P ′ opposing the weight of the door, the upper chain 131 to tendency to relax, for example because the connecting axis of the door is kept in rotation by the engine brake effect. The burglar-proof device 200 can then pivot around the axis 110 in the direction indicated by the arrow F under the action of the spring 210. The upper tooth 230 is therefore brought into forced support between the second wing 122 of the slide 120 If, during the movement of the panel upwards, the upper tooth 230 reaches the height of the blocking notch 231, it penetrates there positively, thus preventing the upward movement from continuing.
On peut observer sur les figures 1, 2 et 3 qu'afin d'obtenir une rotation plus grande du dispositif anti-effraction, la première aile 121 de la coulisse 120 de guidage comporte un dégagement 232 dans laquelle s'engage la dent basse 220 lorsque la dent haute 230 pénètre dans l'encoche 231 de blocage. Symétriquement, dans le but d'obtenir une rotation plus grande du dispositif parachute, la deuxième aile 122 de la coulisse 120 comporte un dégagement 222 dans lequel s'engage la dent haute 230 lorsque la dent basse 220 pénètre dans un trou 221 de blocage. It can be seen in Figures 1, 2 and 3 that in order to obtain a greater rotation of the burglar-resistant device, the first wing 121 of the guide slide 120 has a clearance 232 in which the lower tooth 220 engages when the upper tooth 230 enters the blocking notch 231. Symmetrically, in order to obtain a greater rotation of the parachute device, the second wing 122 of the slide 120 has a clearance 222 in which engages the high tooth 230 when the low tooth 220 enters a blocking hole 221.
Enfin, il convient de noter sur la figure 1 que la chaîne basse 132 est fixée sur le dispositif 200 en un point A d'ancrage décentré par rapport à l'axe latéral 110, de manière à ce que ladite chaîne basse 132 se détende lors de la rotation du dispositif sous l'action de ressort 210, et donc de favoriser celle-ci. Finally, it should be noted in FIG. 1 that the low chain 132 is fixed on the device 200 at a point A of anchoring which is offset relative to the lateral axis 110, so that said low chain 132 relaxes during of the rotation of the device under the spring action 210, and therefore of promoting it.
