Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne un dispositif de verrouillage du type cadenas, et un procédé d'assemblage d'un tel dispositif de verrouillage.The invention relates to a locking device of the padlock type, and to a method of assembling such a locking device.

ARRIERE PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

On connaît des dispositifs de verrouillage du type cadenas, comportant un corps et une anse montée mobile en translation dans le cadenas et aussi en rotation par rapport au cadenas.Locking devices of the padlock type are known, comprising a body and a handle mounted movable in translation in the padlock and also in rotation with respect to the padlock.

Le cadenas comporte en outre un orifice ménagé dans le corps et un organe de rappel logé au fond de cet orifice.The padlock further comprises an orifice made in the body and a return member housed at the bottom of this orifice.

L'anse présente une portion d'extrémité montée mobile dans l'orifice contre l'organe de rappel.The handle has an end portion movably mounted in the orifice against the return member.

L'anse peut ainsi être translatée entre une première position où le cadenas est dans un état ouvert et une seconde position où le cadenas est dans un état fermé. L'anse est aussi pivotante dans le corps.The handle can thus be translated between a first position where the padlock is in an open state and a second position where the padlock is in a closed state. The handle is also pivoting in the body.

Le cadenas comporte en outre un trou ménagé dans le corps et débouchant dans l'orifice où se situe la portion d'extrémité de l'anse, ainsi qu'une goupille assujettie mécaniquement dans le trou et saillant dans l'orifice.The padlock further comprises a hole formed in the body and opening into the orifice where the end portion of the handle is located, as well as a pin mechanically secured in the hole and projecting into the orifice.

La goupille présente ainsi une face d'extrémité située en regard de la portion d'extrémité de l'anse de sorte à former une butée lors de la translation de l'anse depuis sa seconde position vers sa première position.The pin thus has an end face located opposite the end portion of the handle so as to form an abutment during the translation of the handle from its second position to its first position.

Une telle goupille est assemblée sur le corps du cadenas après le montage de la portion d'extrémité de l'anse dans l'orifice du corps, par exemple en étant introduite à force dans le trou dédié.Such a pin is assembled on the body of the padlock after the assembly of the end portion of the handle in the orifice of the body, for example by being forced into the dedicated hole.

Il est préférable que la face d'extrémité de la goupille présente une surface parfaitement plane pour permettre la translation et la rotation de la portion d'extrémité de l'anse dans et par rapport au corps de cadenas. Pour cela, il peut être nécessaire d'usiner la face d'extrémité avant son assemblage dans le trou du corps. Au surplus, après assemblage de la goupille avec le corps, il peut être nécessaire de polir et/ou de traiter le corps de cadenas au moins au niveau de l'extrémité débouchante du trou.It is preferable that the end face of the pin has a perfectly flat surface to allow translation and rotation of the end portion of the shackle in and relative to the padlock body. For this, it may be necessary to machine the end face before assembling it in the body hole. Moreover, after assembly of the pin with the body, it can be necessary to polish and/or treat the padlock body at least at the level of the opening end of the hole.

US1003718 divulgue un cadenas où une pièce de guidage et l'extrémité de l'anse sont dans un orifice du corps et la pièce forme un crochet, dans lequel est maintenue l'extrémité de l'anse. US1003718 discloses a padlock where a guide piece and the end of the shackle are in a hole in the body and the piece forms a hook, in which the end of the shackle is held.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention vise à fournir un dispositif de verrouillage du type cadenas, qui soit particulièrement simple et commode tant à la fabrication qu'à l'utilisation et qui soit aussi particulièrement fiable et durable.The invention aims to provide a locking device of the padlock type, which is particularly simple and convenient both in manufacture and in use and which is also particularly reliable and durable.

L'invention a ainsi pour objet, sous un premier aspect, un dispositif de verrouillage du type cadenas, comportant un corps et une anse montée mobile en translation et en rotation par rapport audit corps, où ledit corps est pourvu d'un orifice et d'une gorge ménagée à l'intérieur dudit orifice, ladite anse comporte une portion d'extrémité amincie montée dans ledit orifice dudit corps, et ledit dispositif comporte en outre un organe de montage assujetti mécaniquement sur ladite portion d'extrémité amincie de ladite anse et logé dans ladite gorge, ledit organe de montage étant configuré pour permettre la rotation de ladite anse par rapport audit corps et aussi la translation de ladite anse dans ledit orifice dudit corps, entre une première position où ledit dispositif est dans un état ouvert, et une seconde position où ledit dispositif est dans un état fermé et ledit organe de montage forme une butée sur ladite portion d'extrémité amincie de ladite anse ; ledit organe de montage présente une hauteur prédéterminée et ladite gorge présente une hauteur au moins égale ou supérieure à la hauteur prédéterminée dudit organe de montage ; ledit dispositif est configuré de sorte que ledit organe de montage est translaté avec ladite portion d'extrémité amincie de ladite anse dans ledit orifice et dans ladite gorge dudit corps, entre lesdites première et seconde positions ; et ladite portion d'extrémité amincie de ladite anse présente une longueur environ égale à ladite hauteur prédéterminée dudit organe de montage, et ladite gorge présente une hauteur bien supérieure à ladite longueur de ladite portion d'extrémité amincie.The invention thus relates, in a first aspect, to a locking device of the padlock type, comprising a body and a handle mounted movable in translation and in rotation relative to said body, where said body is provided with an orifice and a groove provided inside said orifice, said handle comprises a thinned end portion mounted in said orifice of said body, and said device further comprises a mounting member mechanically fastened to said thinned end portion of said handle and housed in said groove, said mounting member being configured to allow the rotation of said handle relative to said body and also the translation of said handle in said orifice of said body, between a first position where said device is in an open state, and a second position where said device is in a closed state and said mounting member forms an abutment on said thinned end portion of said handle; said mounting member has a predetermined height and said groove has a height at least equal to or greater than the predetermined height of said mounting member; said device is configured so that said mounting member is translated with said thinned end portion of said handle in said orifice and in said groove of said body, between said first and second positions; and said tapered end portion of said handle has a length approximately equal to said predetermined height of said mounting member, and said groove has a height much greater than said length of said tapered end portion.

Autrement dit, l'organe de montage du dispositif de verroullage selon l'invention est logé dans la gorge ménagée dans l'orifice, lui-même ménagé dans le corps, et cet organe de montage coopère avec la portion d'extrémité amincie de l'anse pour permettre sa libre rotation et sa translation seulement entre la première position de l'anse et sa seconde position. C'est dans cette première position de l'anse par rapport au corps que l'organe de montage joue le rôle de butée sur sa portion d'extrémité amincie.In other words, the mounting member of the locking device according to the invention is housed in the groove formed in the orifice, itself formed in the body, and this mounting member cooperates with the thinned end portion of the handle to allow its free rotation and its translation only between the first position of the handle and its second position. It is in this first position of the handle relative to the body that the mounting member acts as a stop on its thinned end portion.

Puisque la gorge est ménagée dans l'orficie, la gorge présente un diamètre interne supérieure au diamètre interne de l'orfice. Une telle gorge peut par exemple est réalisée à l'aide d'une fraise clavette pendant ou après la résalisation typiquement par perçage de l'orifice.Since the throat is made in the orficia, the throat has a internal diameter greater than the internal diameter of the orifice. Such a groove can for example be made using a wedge cutter during or after the realization, typically by drilling the orifice.

Le dispositif de verrouillage selon l'invention est donc dépourvu d'une goupille introduite depuis l'extérieur du corps et ne nécessite pas d'usinage et de traitement spécifiques, avant ou après l'assemblage de l'anse avec l'organe de montage dans le corps.The locking device according to the invention is therefore devoid of a pin introduced from outside the body and does not require machining and specific treatment, before or after the assembly of the handle with the mounting member in the body.

DESCRIPTION DETAILLEE D'UN EXEMPLE DE REALISATIONDETAILED DESCRIPTION OF AN EXAMPLE OF REALIZATION

La figure 1 montre de manière éclatée un dispositif de verrouillage du type cadenas 1. Un tel cadenas 1 peut être utilisé par exemple pour permettre la fermeture, de manière sécurisée, d'un article de maroquinerie ou d'un objet quelconque.The figure 1 shows an exploded view of a locking device of the padlock 1 type. Such a padlock 1 can be used, for example, to allow the closing, in a secure manner, of a leather goods item or any other object.

Les figures 2 à 10 montrent en détail le cadenas 1 et son assemblage.The figures 2 to 10 show in detail the padlock 1 and its assembly.

Le cadenas 1 comporte un corps 2, une anse 3 montée mobile en translation dans le corps 2 et aussi en rotation par rapport au corps 2, un organe de montage 4 configuré pour assujettir l'anse 3 dans le corps 2, et un organe de rappel 4.The padlock 1 comprises a body 2, a handle 3 mounted to move in translation in the body 2 and also in rotation with respect to the body 2, a mounting member 4 configured to secure the handle 3 in the body 2, and a reminder 4.

Le corps 2 présente ici une forme globalement parallélépipédique ayant six faces, dont une face supérieure 6.The body 2 here has a generally parallelepipedal shape having six faces, including an upper face 6.

Le corps 2 est pourvu d'un orifice 7, ici circulaire, qui est borgne à une extrémité et qui débouche sur la face supérieure 6 à une extrémité opposée. Cet orifice 7 est réalisé par exemple par perçage.The body 2 is provided with an orifice 7, here circular, which is blind at one end and which opens onto the upper face 6 at an opposite end. This orifice 7 is made for example by drilling.

Le corps 2 est aussi pourvu d'un trou 8, ici circulaire, qui est borgne à une extrémité et qui débouche sur la face supérieure 6 à une extrémité opposée. Ce trou 8 est réalisé par exemple par perçage.The body 2 is also provided with a hole 8, here circular, which is blind at one end and which opens onto the upper face 6 at an opposite end. This hole 8 is made for example by drilling.

L'orifice 7 est pourvu d'un fond 9 duquel s'étend une paroi interne cylindrique 10 jusqu'à la face supérieure 6.The orifice 7 is provided with a bottom 9 from which extends a cylindrical internal wall 10 up to the upper face 6.

L'orifice 7 présente un premier diamètre interne prédéterminé d1, défini par sa paroi interne cylindrique 10, et une première hauteur prédéterminée h1.The orifice 7 has a first predetermined internal diameter d1, defined by its cylindrical internal wall 10, and a first predetermined height h1.

Le corps 2 est en outre pourvu d'une gorge 11 ménagée à l'intérieur de l'orifice 7.The body 2 is further provided with a groove 11 made inside the orifice 7.

La gorge 11 est ici cylindrique et réalisée dans la paroi interne cylindrique 10 de l'orifice 7.The groove 11 is here cylindrical and made in the cylindrical internal wall 10 of the orifice 7.

La gorge 11 présente ainsi un deuxième diamètre interne prédéterminée d2 supérieur au premier diamètre interne prédéterminé d1 de l'orifice 7.The groove 11 thus has a second predetermined internal diameter d2 greater than the first predetermined internal diameter d1 of the orifice 7.

La gorge 11 présente en outre une deuxième hauteur prédéterminée h2 bien inférieure à la première hauteur prédéterminée h1 de l'orifice 7.The groove 11 also has a second predetermined height h2 much lower than the first predetermined height h1 of the orifice 7.

Le trou 8 est pourvu d'un fond 12 duquel s'étend une paroi interne cylindrique 13 jusqu'à la face supérieure 6.The hole 8 is provided with a bottom 12 from which extends a cylindrical internal wall 13 up to the upper face 6.

Le trou 8 présente un troisième diamètre interne prédéterminé d3, défini par sa paroi interne cylindrique 13, et une troisième hauteur prédéterminée h3.The hole 8 has a third predetermined internal diameter d3, defined by its cylindrical internal wall 13, and a third predetermined height h3.

Ici, le troisième diamètre interne prédéterminé d3 du trou 8 est sensiblement égal au premier diamètre interne prédéterminé d1 de l'orifice 7 ; tandis que la troisième hauteur prédéterminée h3 du trou 8 est bien inférieure à la première hauteur prédéterminée h1 de l'orifice 7.Here, the third predetermined internal diameter d3 of the hole 8 is substantially equal to the first predetermined internal diameter d1 of the orifice 7; while the third predetermined height h3 of hole 8 is much lower than the first predetermined height h1 of orifice 7.

L'anse 3 comporte une portion principale en forme de U 14, une portion de verrouillage 15 située à une extrémité de la portion principale en forme de U 14, une portion d'extrémité amincie 16 située à une extrémité opposée de la portion principale en forme de U 14, et une collerette d'extrémité 17 prolongeant la portion d'extrémité amincie 16.The handle 3 comprises a main U-shaped portion 14, a locking portion 15 located at one end of the main U-shaped portion 14, a thinned end portion 16 located at an opposite end of the main U-shape 14, and an end flange 17 extending the thinned end portion 16.

La portion d'extrémité amincie 16 est ainsi située entre la collerette d'extrémité 17 et la portion principale en forme de U 14.The thinned end portion 16 is thus located between the end flange 17 and the U-shaped main portion 14.

La portion d'extrémité amincie 16 présente une première longueur prédéterminée I1.The thinned end portion 16 has a first predetermined length I1.

La portion principale en forme de U 14 est globalement configurée pour se trouver en saillie du corps 2.The U-shaped main portion 14 is generally configured to project from the body 2.

La portion de verrouillage 15 est configurée pour être montée dans le trou 8 du cors 2.The locking portion 15 is configured to be mounted in the hole 8 of the horn 2.

La portion d'extrémité amincie 16 et la collerette d'extrémité 17 sont configurées pour être montées mobiles dans l'orifice 7 du cors 2.The thinned end portion 16 and the end collar 17 are configured to be movably mounted in the orifice 7 of the horn 2.

Une section de la portion principale en forme de U 14, du côté de la portion d'extrémité amincie 16, est aussi configurée pour être montée mobile dans l'orifice 7 du cors 2.A section of the main U-shaped portion 14, on the side of the thinned end portion 16, is also configured to be movably mounted in the orifice 7 of the horn 2.

L'organe de montage est une bague 4 configurée pour être montée au moins partiellement autour de la portion d'extrémité amincie 16 de l'anse 3.The mounting member is a ring 4 configured to be mounted at least partially around the thinned end portion 16 of the handle 3.

La bague 4 est ici fendue et présente une ouverture 18.The ring 4 is here split and has an opening 18.

La bague 4 est réalisée en matière plastique. En variante, la bague peut être métallique.The ring 4 is made of plastic material. Alternatively, the ring can be metallic.

La bague 4 est configurée pour être emmanchée sur la portion d'extrémité amincie 16 de l'anse 3.The ring 4 is configured to be fitted onto the thinned end portion 16 of the handle 3.

La bague 4 présente des propriétés élastiques lui permettant d'être écartée pour son emmanchement sur la portion d'extrémité amincie 16 sans que la bague 4 puisse se retirer de cette portion d'extrémité amincie 16.The ring 4 has elastic properties allowing it to be pushed aside for its fitting on the thinned end portion 16 without the ring 4 being able to withdraw from this thinned end portion 16.

La bague 4 est ainsi assujettie mécaniquement sur la portion d'extrémité amincie 16 de l'anse 3.The ring 4 is thus mechanically secured to the thinned end portion 16 of the handle 3.

La bague 4 est configurée pour être logée dans la gorge 11 de l'orifice 7.The ring 4 is configured to be housed in the groove 11 of the orifice 7.

La bague 4 présente ici une quatrième hauteur prédéterminée h4, sensiblement égale ou légèrement inférieure à la première longueur prédéterminée I1 de la portion d'extrémité amincie 16, et bien inférieure aux première et deuxième hauteurs prédéterminées h1 et h2 respectivement de l'orifice 7 et d la gorge 11.The ring 4 here has a fourth predetermined height h4, substantially equal to or slightly less than the first predetermined length I1 of the thinned end portion 16, and much less than the first and second predetermined heights h1 and h2 respectively of the orifice 7 and d throat 11.

La bague 4 est en outre configurée pour permettre la rotation de l'anse 3 par rapport au corps 2 et aussi la translation de cette anse dans l'orifice 7 du corps, entre une première position où le cadenas 1 est dans un état ouvert, et une seconde position où le cadenas est dans un état fermé.The ring 4 is further configured to allow the rotation of the handle 3 relative to the body 2 and also the translation of this handle in the orifice 7 of the body, between a first position where the padlock 1 is in an open state, and a second position where the padlock is in a closed state.

En particulier, la bague 4 est configurée pour former une butée sur la portion d'extrémité amincie 16 (voir ci-après).In particular, the ring 4 is configured to form an abutment on the thinned end portion 16 (see below).

L'organe de rappel 5 est ici formé par un ressort hélicoïdal et est configuré pour être logé dans l'orifice 7 du corps 2, entre le fond 9 de l'orifice et la collerette d'extrémité 17 de l'anse 3.The return member 5 is here formed by a helical spring and is configured to be housed in the orifice 7 of the body 2, between the bottom 9 of the orifice and the end collar 17 of the handle 3.

L'organe de rappel 5 est ainsi configuré pour exercer une force sur la collerette d'extrémité 17 et donc sur la portion d'extrémité amincie 16 de l'anse 3 pour la déplacer en translation depuis la seconde position vers la première position.The return member 5 is thus configured to exert a force on the end flange 17 and therefore on the thinned end portion 16 of the handle 3 to move it in translation from the second position to the first position.

L'assemblage du cadenas 1 décrit en référence aux figures 1 à 10 se fait de la manière expliquée ci-dessous.The assembly of padlock 1 described with reference to figures 1 to 10 is done as explained below.

L'organe de rappel 5 est introduit dans l'orifice 7 du corps 2 et repose sur le fond 9 de cet orifice 7.The return member 5 is introduced into the orifice 7 of the body 2 and rests on the bottom 9 of this orifice 7.

La bague 4 est emmanchée sur la portion d'extrémité amincie 16 de l'anse 3 en étant écartée puis resserée autour de cette portion d'extrémité amincie 16. Cela signifie que l'ouverture 18 de la bague 4 varie lors de son emmanchement sur l'anse 3.The ring 4 is fitted onto the thinned end portion 16 of the handle 3 by being pushed aside then tightened around this thinned end portion 16. This means that the opening 18 of the ring 4 varies during its fitting on the cove 3.

La bague 4 est ainsi assujettie mécaniquement sur l'anse 3.The ring 4 is thus mechanically secured to the handle 3.

L'anse 3 est introduite dans l'orifice 7, du côté de sa portion d'extrémité amincie 16, jusqu'à loger la bague 4 dans la gorge 11 ménagée dans l'orifice 7.The handle 3 is introduced into the orifice 7, on the side of its thinned end portion 16, until the ring 4 is housed in the groove 11 made in the orifice 7.

La collerette d'extrémité 17 de l'anse 3 vient au contact de l'organe de rappel 5.The end flange 17 of the handle 3 comes into contact with the return member 5.

L'anse 3 est ainsi assujettie mécaniquement au corps 2, avec la bague 4 qui forme une butée sur la portion d'extrémité amincie 16 de l'anse 3 pour empêcher le retrait de l'anse 3 du corps 2.The handle 3 is thus mechanically secured to the body 2, with the ring 4 which forms an abutment on the thinned end portion 16 of the handle 3 to prevent the removal of the handle 3 from the body 2.

La bague 4 permet en outre à l'anse 3, dont une section de sa portion principale 14, sa portion d'extrémité amincie 16 et sa collerette d'extrémité 17, de tourner par rapport au corps 2, et de coulisser dans son orifice 7 et dans sa gorge 11, entre la première position où le cadenas 1 est dans l'état ouvert (figures 5 et 7), et une seconde position où le cadenas 1 est dans l'état fermé (figures 8 et 10).The ring 4 also allows the handle 3, including a section of its main portion 14, its thinned end portion 16 and its end flange 17, to rotate relative to the body 2, and to slide in its orifice 7 and in its groove 11, between the first position where the padlock 1 is in the open state ( figures 5 and 7 ), and a second position where the padlock 1 is in the closed state ( figures 8 and 10 ).

Dans l'état ouvert du cadenas 1, l'organe de rappel 5 déplace l'anse 3 dans l'orifice 7 et la bague 4 logée dans la gorge 11 jusqu'à ce que la collerette d'extrémité 17 de l'anse 3 vienne en butée contre la bague 4 et cette dernière en butée contre des bords de la gorge 11.In the open state of the padlock 1, the return member 5 moves the handle 3 into the orifice 7 and the ring 4 housed in the groove 11 until the end flange 17 of the handle 3 abuts against the ring 4 and the latter abuts against the edges of the groove 11.

La portion de verrouillage 15 de l'anse 3 est en dehors du trou 8 du corps 2 et l'anse peut tourner par rapport au corps 2.The locking portion 15 of the handle 3 is outside the hole 8 of the body 2 and the handle can rotate relative to the body 2.

Dans l'état fermé du cadenas 1, l'anse 3 est déplacée dans l'orifice 7 à l'encontre de l'organe de rappel 5 et la bague 4 logée dans la gorge 11 est déplacée dans cette dernière.In the closed state of the padlock 1, the shackle 3 is moved in the orifice 7 against the return member 5 and the ring 4 housed in the groove 11 is moved in the latter.

La portion de verrouillage 15 de l'anse 3 est introduite dans le trou 8 du corps 2 et l'anse ne peut plus tourner par rapport au corps 2.The locking portion 15 of the handle 3 is introduced into the hole 8 of the body 2 and the handle can no longer rotate relative to the body 2.

Ici, le cadenas 1 est ainsi configuré de sorte que la bague 4 est translatée avec la portion d'extrémité amincie 16 de l'anse 3 dans l'orifice 7 et dans la gorge 11 du corps 2, entre lesdites première et seconde positions.Here, the padlock 1 is thus configured so that the ring 4 is translated with the thinned end portion 16 of the handle 3 in the orifice 7 and in the groove 11 of the body 2, between said first and second positions.

La deuxième hauteur prédéterminée h2 de la gorge 11 définit une course de l'anse 3 entre ses première et seconde positions.The second predetermined height h2 of the groove 11 defines a stroke of the handle 3 between its first and second positions.

Les figures 11 à 20 montrent en détail une variante de réalisation du cadenas 1 et son assemblage. Le cadenas 1 selon sa variante de réalisation est très similaire à celui décrit plus haut, à l'exception de la hauteur de la gorge et de la longueur de la portion d'extrémité amincie de l'anse (voir ci-dessous).The figures 11 to 20 show in detail an alternative embodiment of the padlock 1 and its assembly. The padlock 1 according to its alternative embodiment is very similar to that described above, with the exception of the height of the groove and the length of the thinned end portion of the handle (see below).

En particulier, le cadenas comporte un corps 2, une anse 3 montée mobile en translation dans le corps 2 et aussi en rotation par rapport au corps 2, un organe de montage 4 configuré pour assujettir l'anse 3 dans le corps 2, et un organe de rappel 4.In particular, the padlock comprises a body 2, a handle 3 mounted movable in translation in the body 2 and also in rotation relative to the body 2, a mounting member 4 configured to secure the handle 3 in the body 2, and a recall device 4.

Le corps 2 a forme globalement parallélépipédique ayant six faces, dont une face supérieure 6. Le corps 2 est pourvu d'un orifice 7 circulaire, borgne à une extrémité et qui débouche sur la face supérieure 6 à une extrémité opposée ; et d'un trou 8 circulaire, borgne à une extrémité et qui débouche sur la face supérieure 6 à une extrémité opposée.The body 2 has a generally parallelepipedal shape having six faces, including an upper face 6. The body 2 is provided with a circular orifice 7, blind at one end and which opens onto the upper face 6 at an opposite end; and a circular hole 8, blind at one end and which opens onto the upper face 6 at an opposite end.

L'orifice 7 est pourvu d'un fond 9 duquel s'étend une paroi interne cylindrique 10 jusqu'à la face supérieure 6. L'orifice 7 présente un premier diamètre interne prédéterminé d1, défini par sa paroi interne cylindrique 10, et une première hauteur prédéterminée h1.The orifice 7 is provided with a bottom 9 from which a cylindrical internal wall 10 extends as far as the upper face 6. The orifice 7 has a first predetermined internal diameter d1, defined by its cylindrical internal wall 10, and a first predetermined height h1.

Le corps 2 est en outre pourvu d'une gorge 11 ménagée à l'intérieur de l'orifice 7. La gorge 11 est cylindrique et réalisée dans la paroi interne cylindrique 10 de l'orifice 7. La gorge 11 présente ainsi un deuxième diamètre interne prédéterminée d2 supérieur au premier diamètre interne prédéterminé d1 de l'orifice 7. La gorge 11 présente en outre une deuxième hauteur prédéterminée h'2 bien inférieure à la première hauteur prédéterminée h1 de l'orifice 7.The body 2 is further provided with a groove 11 made inside the orifice 7. The groove 11 is cylindrical and made in the cylindrical internal wall 10 of the orifice 7. The groove 11 thus has a second diameter predetermined internal diameter d2 greater than the first predetermined internal diameter d1 of the orifice 7. The groove 11 also has a second predetermined height h'2 much lower than the first predetermined height h1 of the orifice 7.

Le trou 8 est pourvu d'un fond 12 duquel s'étend une paroi interne cylindrique 13 jusqu'à la face supérieure 6. Le trou 8 présente un troisième diamètre interne prédéterminé d3, défini par sa paroi interne cylindrique 13, et une troisième hauteur prédéterminée h3. Ici, le troisième diamètre interne prédéterminé d3 du trou 8 est sensiblement égal au premier diamètre interne prédéterminé d1 de l'orifice 7 ; tandis que la troisième hauteur prédéterminée h3 du trou 8 est bien inférieure à la première hauteur prédéterminée h1 de l'orifice 7.The hole 8 is provided with a bottom 12 from which extends a cylindrical internal wall 13 up to the upper face 6. The hole 8 has a third predetermined internal diameter d3, defined by its cylindrical internal wall 13, and a third height predetermined h3. Here, the third predetermined internal diameter d3 of the hole 8 is substantially equal to the first predetermined internal diameter d1 of the orifice 7; while the third predetermined height h3 of hole 8 is much lower than the first predetermined height h1 of orifice 7.

L'anse 3 comporte une portion principale en forme de U 14, une portion de verrouillage 15 située à une extrémité de la portion principale en forme de U 14, une portion d'extrémité amincie 16 située à une extrémité opposée de la portion principale en forme de U 14, et une collerette d'extrémité 17 prolongeant la portion d'extrémité amincie 16.The handle 3 comprises a main U-shaped portion 14, a locking portion 15 located at one end of the main U-shaped portion 14, a thinned end portion 16 located at an opposite end of the main U-shape 14, and an end flange 17 extending the thinned end portion 16.

La portion d'extrémité amincie 16 est ainsi située entre la collerette d'extrémité 17 et la portion principale en forme de U 14.The thinned end portion 16 is thus located between the end flange 17 and the U-shaped main portion 14.

La portion d'extrémité amincie 16 présente une première longueur prédéterminée l'1, ici bien supérieure à la deuxième hauteur prédéterminée h'2 de la gorge 11.The thinned end portion 16 has a first predetermined length l'1, here much greater than the second predetermined height h'2 of the groove 11.

La portion principale en forme de U 14 est globalement configurée pour se trouver en saillie du corps 2. La portion de verrouillage 15 est configurée pour être montée dans le trou 8 du cors 2. La portion d'extrémité amincie 16 et la collerette d'extrémité 17 sont configurées pour être montées mobiles dans l'orifice 7 du cors 2. Une section de la portion principale en forme de U 14, du côté de la portion d'extrémité amincie 16, est aussi configurée pour être montée mobile dans l'orifice 7 du cors 2.The U-shaped main portion 14 is generally configured to project from the body 2. The locking portion 15 is configured to be mounted in the hole 8 of the horn 2. The thinned end portion 16 and the flange of end 17 are configured to be movably mounted in the orifice 7 of the body 2. A section of the main U-shaped portion 14, on the side of the thinned end portion 16, is also configured to be movably mounted in the orifice 7 of horn 2.

L'organe de montage est une bague 4 configurée pour être montée au moins partiellement autour de la portion d'extrémité amincie 16 de l'anse 3.The mounting member is a ring 4 configured to be mounted at least partially around the thinned end portion 16 of the handle 3.

La bague 4 est ici fendue et présente une ouverture 18. La bague 4 est réalisée en matière plastique. En variante, la bague peut être métallique. La bague 4 est configurée pour être emmanchée sur la portion d'extrémité amincie 16 de l'anse 3. La bague 4 présente des propriétés élastiques lui permettant d'être écartée pour son emmanchement sur la portion d'extrémité amincie 16 sans que la bague 4 puisse se retirer de cette portion d'extrémité amincie 16. La bague 4 est ainsi assujettie mécaniquement sur la portion d'extrémité amincie 16 de l'anse 3. La bague 4 est configurée pour être logée dans la gorge 11 de l'orifice 7.The ring 4 is here split and has an opening 18. The ring 4 is made of plastic material. Alternatively, the ring can be metallic. The ring 4 is configured to be fitted onto the thinned end portion 16 of the handle 3. The ring 4 has elastic properties allowing it to be pushed aside for its fitting on the thinned end portion 16 without the ring 4 being able to withdraw from this thinned end portion 16. The ring 4 is thus mechanically secured on the thinned end portion 16 of the handle 3. Ring 4 is configured to be housed in groove 11 of orifice 7.

La bague 4 présente ici une quatrième hauteur prédéterminée h4, bien inférieure à la première longueur prédéterminée l'1 de la portion d'extrémité amincie 16, et bien inférieure à la première hauteur prédéterminée h1 de l'orifice 7.The ring 4 here has a fourth predetermined height h4, much less than the first predetermined length l'1 of the thinned end portion 16, and much less than the first predetermined height h1 of the orifice 7.

La quatrième hauteur prédéterminée h4 de la bague 4 est ici environ égale ou légèrement inférieure à la deuxième hauteur prédéterminée h'2 de la gorge 11. Cela signifie que la bague 4 est logée et fixe et dans la gorge 11.The fourth predetermined height h4 of the ring 4 is here approximately equal to or slightly less than the second predetermined height h'2 of the groove 11. This means that the ring 4 is housed and fixed and in the groove 11.

La bague 4 est en outre configurée pour permettre la rotation de l'anse 3 par rapport au corps 2 et aussi la translation de cette anse 3 dans l'orifice 7 du corps, entre une première position où le cadenas 1 est dans un état ouvert, et une seconde position où le cadenas est dans un état fermé. En particulier, la bague 4 est configurée pour former une butée sur la portion d'extrémité amincie 16 (voir ci-après).The ring 4 is further configured to allow the rotation of the handle 3 relative to the body 2 and also the translation of this handle 3 in the orifice 7 of the body, between a first position where the padlock 1 is in an open state , and a second position where the padlock is in a closed state. In particular, the ring 4 is configured to form an abutment on the thinned end portion 16 (see below).

L'organe de rappel 5 est ici formé par un ressort hélicoïdal et est configuré pour être logé dans l'orifice 7 du corps 2, entre le fond 9 de l'orifice et la collerette d'extrémité 17 de l'anse 3. L'organe de rappel 5 est ainsi configuré pour exercer une force sur la collerette d'extrémité 17 et donc sur la portion d'extrémité amincie 16 de l'anse 3 pour la déplacer en translation depuis la seconde position vers la première position, la bague 4 restant fixe dans la gorge 11.The return member 5 is here formed by a helical spring and is configured to be housed in the orifice 7 of the body 2, between the bottom 9 of the orifice and the end collar 17 of the handle 3. The return member 5 is thus configured to exert a force on the end flange 17 and therefore on the thinned end portion 16 of the handle 3 to move it in translation from the second position to the first position, the ring 4 remaining fixed in groove 11.

L'assemblage du cadenas 1 décrit en référence aux figures 11 à 20 se fait de la manière expliquée ci-dessous.The assembly of padlock 1 described with reference to figures 11 to 20 is done as explained below.

L'organe de rappel 5 est introduit dans l'orifice 7 du corps 2 et repose sur le fond 9 de cet orifice 7.The return member 5 is introduced into the orifice 7 of the body 2 and rests on the bottom 9 of this orifice 7.

La bague 4 est emmanchée sur la portion d'extrémité amincie 16 de l'anse 3 en étant écartée puis resserée autour de cette portion d'extrémité amincie 16. Cela signifie que l'ouverture 18 de la bague 4 varie lors de son emmanchement sur l'anse 3.The ring 4 is fitted onto the thinned end portion 16 of the handle 3 by being pushed aside then tightened around this thinned end portion 16. This means that the opening 18 of the ring 4 varies during its fitting on the cove 3.

La bague 4 est ainsi assujettie mécaniquement sur l'anse 3.The ring 4 is thus mechanically secured to the handle 3.

L'anse 3 est introduite dans l'orifice 7, du côté de sa portion d'extrémité amincie 16, jusqu'à loger la bague 4 dans la gorge 11 ménagée dans l'orifice 7.The handle 3 is introduced into the orifice 7, on the side of its thinned end portion 16, until the ring 4 is housed in the groove 11 formed in the orifice 7.

La collerette d'extrémité 17 de l'anse 3 vient au contact de l'organe de rappel 5.The end flange 17 of the handle 3 comes into contact with the return member 5.

L'anse 3 est ainsi assujettie mécaniquement au corps 2, avec la bague 4 qui forme une butée sur la portion d'extrémité amincie 16 de l'anse 3 pour empêcher le retrait de l'anse 3 du corps 2.The handle 3 is thus mechanically secured to the body 2, with the ring 4 which forms an abutment on the thinned end portion 16 of the handle 3 to prevent the removal of the handle 3 from the body 2.

La bague 4 permet en outre à l'anse 3, dont une section de sa portion principale 14, sa portion d'extrémité amincie 16 et sa collerette d'extrémité 17, de tourner par rapport au corps 2, et de coulisser dans son orifice 7, entre la première position où le cadenas 1 est dans l'état ouvert (figures 5 et 7), et une seconde position où le cadenas 1 est dans l'état fermé (figures 8 et 10).The ring 4 also allows the handle 3, including a section of its main portion 14, its thinned end portion 16 and its end flange 17, to rotate relative to the body 2, and to slide in its orifice 7, between the first position where padlock 1 is in the open state ( figures 5 and 7 ), and a second position where the padlock 1 is in the closed state ( figures 8 and 10 ).

Dans l'état ouvert du cadenas 1, l'organe de rappel 5 déplace l'anse 3 dans l'orifice 7 jusqu'à ce que la collerette d'extrémité 17 de l'anse 3 vienne en butée contre la bague 4.In the open state of padlock 1, return member 5 moves shackle 3 into orifice 7 until end collar 17 of shackle 3 comes into abutment against ring 4.

La portion de verrouillage 15 de l'anse 3 est en dehors du trou 8 du corps 2 et l'anse peut tourner par rapport au corps 2.The locking portion 15 of the handle 3 is outside the hole 8 of the body 2 and the handle can rotate relative to the body 2.

Dans l'état fermé du cadenas 1, l'anse 3 est déplacée dans l'orifice 7 à l'encontre de l'organe de rappel 5, la bague 4 restant fixe dans la gorge 11. La portion d'extrémité amincie 16 de l'anse 3 coulisse ainsi dans la bague 4.In the closed state of the padlock 1, the shackle 3 is moved in the orifice 7 against the return member 5, the ring 4 remaining fixed in the groove 11. The thinned end portion 16 of the handle 3 thus slides in the ring 4.

La portion de verrouillage 15 de l'anse 3 est introduite dans le trou 8 du corps 2 et l'anse ne peut plus tourner par rapport au corps 2.The locking portion 15 of the handle 3 is introduced into the hole 8 of the body 2 and the handle can no longer rotate relative to the body 2.

Ici, le cadenas 1 est ainsi configuré de sorte que avec la portion d'extrémité amincie 16 de l'anse 3 est translatée dans la bague 4 et dans l'orifice 7 entre lesdites première et seconde positions.Here, the padlock 1 is thus configured so that with the thinned end portion 16 of the handle 3 is translated in the ring 4 and in the orifice 7 between said first and second positions.

La première longueur prédéterminée l'1 de la portion d'extrémité amincie 16 de l'anse 3 définit une course de l'anse 3 entre ses première et seconde positions.The first predetermined length l'1 of the thinned end portion 16 of the handle 3 defines a travel of the handle 3 between its first and second positions.

Dans des variantes non illustrées :

  • l'organe de montage est une bague fermée plutôt qu'une bague fendue, emmanchée à force par une extrémité de l'anse ;
  • l'anse présente une forme différente de celles décrites plus haut, par exemple une forme rectangulaire ;
  • l'organe de rappel n'est pas un ressort hélicoïdal mais plutôt un ressort lame ou bien un élastomère ; et/ou
  • le corps présente une forme globalement circulaire plutôt que parallélépipédique ou bien ne autre forme.
In variants not shown:
  • the mounting member is a closed ring rather than a split ring, force-fitted by one end of the handle;
  • the handle has a shape different from those described above, for example a rectangular shape;
  • the return member is not a coil spring but rather a leaf spring or an elastomer; and or
  • the body has a generally circular shape rather than a parallelepipedal or other shape.

On rappelle plus généralement que l'invention ne se limite pas aux exemples décrits et représentés.It is recalled more generally that the invention is not limited to the examples described and represented.
