Abstract
Description
La présente invention concerne une clé de précision pour des serrures, du type de celles qui sont en forme de pale et qui au niveau de leur extrémité, comprennent un balancier longitudinal qui est installé dans une fenêtre de la clé et qui, dans cette fenêtre, a la capacité d'effectuer deux mouvements de rotation combinés et limités, l'un, de rotation transversale dans un plan perpendiculaire à la pale, l'autre, de rotation latérale dans le plan de la pale. La fonction de ce balancier longitudinal est d'intervenir dans l'établissement d'une condition de clé d'ouverture préalable et additionnelle à celle des jeux conventionnels d'ergots de combinaison, en imposant une position concrète du balancier pour qu'un ou plusieurs ergots auxiliaires de combinaison puissent agir.The present invention relates to a precision key for locks, of the type which are blade-shaped and which at their end comprise a longitudinal beam which is installed in a window of the key and which, in this window, has the ability to perform two combined and limited rotational movements, one of transverse rotation in a plane perpendicular to the blade, the other of lateral rotation in the plane of the blade. The function of this longitudinal pendulum is to intervene in the establishment of a condition of opening key prior and additional to that of the conventional games of combination pins, by imposing a concrete position of the pendulum for one or more Auxiliary combination pins may act.
Dans ce domaine, il est connu d'utiliser un balancier longitudinal avec une section d'épaisseur uniforme dans la direction de la largeur de la pale plate et qui, en vue dans la direction transversale de la clé depuis son extrémité avant (la plus proche de la pointe de la clé), s'élargit jusqu'à son extrémité arrière (la plus éloignée de la pointe de la clé), où il se termine de manière arrondie avec une saillie centrale.In this field, it is known to use a longitudinal beam with a section of uniform thickness in the width direction of the flat blade and which, in view in the transverse direction of the key from its front end (the closest from the tip of the key), widens to its rear end (farthest from the tip of the key), where it terminates in a rounded manner with a central projection.
Dans ce type de balancier longitudinal, on établit une double butée pour la rotation transversale : dans l'extrémité arrière par rapport à la pointe de la clé, on forme une saillie frontale centrale entre les plans latéraux et qui joue avec chacun des rebords qui sont le prolongement des faces les plus grandes de la pale plate et qui pénètrent dans le bord arrière de la fenêtre par rapport à la pointe de la clé dans laquelle agit le balancier ; et dans l'extrémité avant par rapport à l'extrémité de la clé, il forme deux entailles transversales pratiquées dans le matériau de la pale plate, logeant entre elles une clavette cylindrique transversale fine qui est d'un diamètre beaucoup plus petit que celui de l'axe d'articulation du balancier. Cette solution manque de sécurité parce que les deux butées ne pourront jamais agir en même temps et combiner leur action ; en outre, la grande précision d'exécution qui est requise et la faible marge de tolérance disponible dans une exécution de dimensions aussi réduites font qu'il est fréquent que la fonction de butée de rotation est remplie exclusivement par la faible clavette cylindrique.In this type of longitudinal beam, a double stop is established for the transverse rotation: in the rear end with respect to the tip of the key, a central frontal projection is formed between the lateral planes and which plays with each of the flanges which are the extension of the largest faces of the flat blade and which penetrate into the rear edge of the window relative to the tip of the key in which the pendulum acts; and in the front end with respect to the end of the key, it forms two transverse cuts made in the material of the flat blade, housing between them a fine transverse cylindrical key which is of a diameter much smaller than that of the axis of articulation of the balance. This solution lacks security because the two stops can never act at the same time and combine their action; moreover, the great precision of execution which is required and the small margin of tolerance available in an execution of so small dimensions make that it is frequent that the stop function of rotation is filled exclusively by the weak cylindrical key.
En outre, réaliser une butée arrière en ce qui concerne l'extrémité de la clé par cette saillie frontale réduit la surface disponible pour l'actionnement des ergots de combinaison auxiliaires ; suite à cela dans les faces les plus grandes de la pale plate il a fallu effectuer de profondes découpes courbes pour agrandir l'accès des ergots de combinaison auxiliaires à l'extrémité arrière du balancier ; ce qui, à son tour, a comme conséquence négative d'affaiblir la résistance de la pale plate et de limiter la capacité de réaliser des systèmes appelés « systèmes à rainures multiples » qui sont employés pour des clés de haute sécurité ; à ce sujet il faut tenir compte que le fait de placer les rebords de la butée empêche, comme cela a déjà été mentionné, la diminution de l'épaisseur de la pale plate à cet endroit de manière intempestive parce que cela rapprocherait lesdits rebords et le trajet de la rotation transversale serait réduit.In addition, making a backstop with respect to the end of the key by this frontal projection reduces the area available for actuation of the auxiliary combination pins; as a result of this in the larger faces of the flat blade it was necessary to make deep curved cuts to enlarge the access of the auxiliary combination pins to the rear end of the balance; which, in turn, has the negative consequence of weakening the resistance of the blade and limiting the ability to perform systems called "multiple groove systems" which are used for high security keys; in this regard it must be taken into account that the fact of placing the edges of the abutment prevents, as already mentioned, the reduction of the thickness of the flat blade at this location inadvertently because it would bring said edges and the transverse rotation path would be reduced.
Quant à la rotation latérale, ce type de balancier agit sur une fenêtre qui a une forme de secteur circulaire qui dans son extrémité avant la plus étroite commence à s'élargir derrière l'axe autour duquel tourne le balancier. Avec cette configuration, la butée de la rotation latérale est disposée entre les flancs latéraux plats du balancier et les parois radiales, également plates, de la fenêtre sectorielle ; pour que cette forme de butée puisse être réalisée ainsi, une grande précision est également nécessaire sinon l'effort de la butée sera exercé sur son propre axe d'articulation ainsi que sur la clavette cylindrique mentionnée ci-dessus.As for the lateral rotation, this type of balance acts on a window which has a shape of circular sector which in its narrow front end begins to widen behind the axis around which the pendulum turns. With this configuration, the stop of the lateral rotation is arranged between the flat lateral flanks of the balance and the radial walls, also flat, of the sectorial window; so that this form of abutment can be achieved in this way, great precision is also necessary if the force of the abutment will be exerted on its own axis of articulation as well as on the cylindrical key mentioned above.
Face à cet état de choses, cette invention préconise une clé de précision pour serrures, avec une pale qui, au niveau de sa pointe, comprend un balancier longitudinal capable de deux mouvements de rotation combinés et limités, l'un, de rotation transversale, dans un plan perpendiculaire à la pale, l'autre, de rotation latérale, dans le plan de la pale. En désignant comme extrémité avant l'extrémité la plus proche de la pointe de la pale et comme extrémité arrière l'extrémité la plus éloignée de celle-ci, l'invention consiste en ce que ce balancier longitudinal, dans son extrémité avant, ou pied de balancier, forme une profonde cavité doublement arquée qui est parallèle à l'axe d'équilibre du balancier longitudinal et qui est de profil concave dans la direction longitudinale de la pale et de profil convexe dans la direction perpendiculaire à celle antérieure, la cavité doublement arquée étant susceptible de recevoir en son sein une butée de rotation transversale qui est intégrée d'une seule pièce ou rajoutée à la pale et dont la section opérationnelle est de l'ordre de celle de cet axe d'équilibre ; en ce que, dans son extrémité arrière, ou tête de balancier, le balancier longitudinal forme un renflement semblable à une sphère ; en ce que, dans sa section de démarrage du renflement, cette tête de balancier est reliée avec le pied de balancier au moyen de flancs plats et parallèles entre eux qui sont situés entre deux parois convergentes d'une fenêtre qui est pratiquée dans la pale pour le jeu rotatif du balancier longitudinal, ces parois convergentes étant étendues jusqu'à l'extrémité avant de la fenêtre au-delà de la butée de rotation transversale ; et en ce que, dans la rotation latérale du balancier longitudinal, entre les flancs plats et parallèles à ce dernier et les parois convergentes de la fenêtre, il existe un jeu d'articulation inférieur à celui existant entre la cavité doublement arquée et la butée de rotation transversale.Faced with this state of affairs, this invention recommends a precision key for locks, with a blade which, at its tip, comprises a longitudinal balance capable of two combined and limited rotational movements, one of transverse rotation, in a plane perpendicular to the blade, the other, lateral rotation, in the plane of the blade. Designating as the end end closest to the tip of the blade and as the rear end the end farthest from it, the invention consists in that this longitudinal balance, in its front end, or foot of a pendulum, forms a deep doubly arched cavity which is parallel to the axis of equilibrium of the longitudinal balance and which is concave in profile in the longitudinal direction of the blade and of convex profile in the direction perpendicular to that prior, the cavity doubly arcuate being capable of receiving within it a transverse rotation stop which is integrated in one piece or added to the blade and whose operational section is of the order of that of this equilibrium axis; in that, in its rear end, or balance head, the longitudinal beam forms a bulge similar to a sphere; in that, in its bulge starting section, this rocker head is connected with the rocker foot by means of flat and parallel flanks between them which are located between two convergent walls of a window which is formed in the blade to the rotating play of the longitudinal balance, these convergent walls being extended to the front end of the window beyond the transverse rotation stop; and in that, in the lateral rotation of the longitudinal beam, between the flat flanks and parallel to the latter and the converging walls of the window, there is a hinge clearance lower than that existing between the doubly-arcuate cavity and the abutment of transverse rotation.
La tête de balancier presque sphérique est arrondie au niveau ses faces supérieure et inférieure qui sont orientées vers les faces les plus grandes de la pale et, dans ses flancs orientés vers les faces les plus petites de la pale, cette tête de balancier présente des faces plates qui, par rapport à la rotation latérale du balancier longitudinal, sont éloignés des facettes respectives de la fenêtre avec une amplitude plus importante que celle existant entre les flancs plats et parallèles et les parois convergentes, et inférieure à celle existant entre la cavité doublement arquée et la butée de rotation transversale.The almost spherical balance head is rounded at its upper and lower faces which are oriented towards the largest faces of the blade and, in its flanks oriented towards the smallest faces of the blade, this rocker head has flat faces which, with respect to the lateral rotation of the longitudinal beam, are remote from the respective facets of the blade. the window with an amplitude greater than that existing between the flat and parallel flanks and the converging walls, and less than that existing between the doubly-arcuate cavity and the transverse rotation stop.
On peut observer, que dans cette invention on établit une seule butée de rotation transversale, mais c'est une butée bien robuste qui a une section opérationnelle aussi considérable que celle de l'axe d'équilibre lui-même et qui, grâce à la conception adoptée, garantit que la butée va toujours être exercée avec les moyens prévus pour cela.It can be seen that in this invention a single transverse rotation stop is established, but it is a sturdy stop which has an operational section as large as that of the equilibrium axis itself and which, thanks to the adopted design, ensures that the stop will always be exercised with the means provided for this.
Une conséquence de ce concept est que la tête de balancier est libérée d'autres fonctions qui ne sont pas sa mission principale, celle de permettre de la manière plus vaste et efficace possible d'établir une clé auxiliaire et préalable qui permet l'ouverture avec la clé du jeu principal des ergots conventionnels. De cette manière, il est possible de : surdimensionner la tête jusqu'à une forme presque sphérique, en offrant de plus grandes possibilités de combinaison aux ergots auxiliaires ; une plus grande marge de tolérance dans le positionnement de ces ergots auxiliaires ; une plus grande accessibilité qui permette d'éliminer les découpes concaves de la pale annexes à la fenêtre d'opération du balancier, ce qui économise des opérations compliquées et renforce la pale de la clé ; éliminer les rebords de butée extraits comme un prolongement des faces les plus grandes de la pale, ce qui supprime la condition de taille minimale de la pale à ce sujet, en offrant la possibilité d'exécuter des pales avec des systèmes à rainures multiples ; une meilleure adaptation de la forme de la fenêtre à la forme du balancier.A consequence of this concept is that the balance head is released from other functions that are not its main mission, that of allowing in the widest and most effective way possible to establish an auxiliary and preliminary key that allows the opening with the key to the main game of conventional pins. In this way, it is possible to: oversize the head to an almost spherical shape, offering greater possibilities of combination with the auxiliary pins; a greater margin of tolerance in the positioning of these auxiliary pins; greater accessibility that eliminates the concave cutouts of the blade annexes to the operation window of the balance, which saves complicated operations and strengthens the blade of the key; eliminating the extracted abutment ledges as an extension of the largest faces of the blade, which eliminates the minimum blade size requirement thereon, providing the possibility of running blades with multiple groove systems; a better adaptation of the shape of the window to the shape of the pendulum.
Quant à la rotation latérale, désormais le contact de butée ne se trouve pas entre deux surfaces plates étendues, mais il peut arriver à être ponctuel, plus précis et actionné par les moyens prévus à cet effet et non par d'autres moyens.As for the lateral rotation, now the stop contact is not between two extended flat surfaces, but it can happen to be punctual, more precise and operated by the means provided for this purpose and not by other means.
Une variante de réalisation de l'invention consiste en ce que la butée de rotation transversale est rajoutée et est constituée d'une goupille du même diamètre opérationnel que celui de l'axe d'équilibre du balancier longitudinal ; c'est-à-dire, que l'axe d'équilibre et la butée de rotation transversale peuvent être la même pièce, ce qui permet une économie.An alternative embodiment of the invention consists in that the transverse rotation stop is added and consists of a pin of the same operating diameter as the axis of equilibrium of the longitudinal balance; that is, the equilibrium axis and the transverse rotation stop may be the same piece, which allows economy.
Une autre variante de réalisation de l'invention consiste en ce que la butée de rotation transversale est entière et est constituée d'une nervure de section transversale opérationnelle équivalente à celle de l'axe d'équilibre et taillée dans la pale elle-même de telle sorte qu'elle ait un profil convexe dans la direction longitudinale de la pale et un profil concave dans la direction perpendiculaire à celle-ci. Cette solution permet la réalisation de la butée par une opération d'usinage simple qui évite des opérations d'assemblage de cette dernière et garantit une plus grande précision que celle d'un assemblage.Another variant embodiment of the invention consists in the fact that the transverse rotation abutment is entire and consists of a rib of operational cross-section equivalent to that of the equilibrium axis and cut into the blade itself. such that it has a convex profile in the longitudinal direction of the blade and a concave profile in the direction perpendicular thereto. This solution allows the realization of the abutment by a simple machining operation that avoids assembly operations of the latter and ensures greater accuracy than that of an assembly.
