Description

DESCRIPTION DESCRIPTION
Serrure pour coffres d'appointLock for extra boxes
La présente invention se rapporte à des serrures pour coffres d'appoint et en particulier pour boîtes ou coffres destinés pour être installé à l'aide d'un porte bagages sur le toit d'un véhicule ou remorque.The present invention relates to locks for extra safes and in particular for boxes or safes intended to be installed using a luggage rack on the roof of a vehicle or trailer.
Ces genres de coffres comprennent en général une partie en forme de cuvette fixe destinée à recevoir du matériel et un couvercle de fermeture pivotant. Ils sont souvent utilisés pour transporter les bagages et notamment des ski, ou autre matériel de loisir, lors de déplacements vers des lieux de vacances.These types of cases generally include a part in the form of a fixed bowl intended to receive equipment and a pivoting closure cover. They are often used to transport luggage and in particular skis, or other leisure equipment, when traveling to vacation spots.
Afin de répondre aux besoins, ces coffres doivent être le plus volumineux possible tout en restant solide, léger et aérodynamique.To meet the needs, these boxes must be as large as possible while remaining solid, light and aerodynamic.
Ils doivent être munis de moyens de verrouillage à l'aide de serrures, qui sont généralement en nombre de deux, disposés sur un côté latéral du couvercle du coffre. Comme les coffres ont, en général, une forme allongé, les serrures se trouvent donc assez éloignées l'une de l'autre. Au début, ces serrures étaient munies de crochets actionnés par le cylindre ou barillet de la serrure à l'aide d'une clé. Lorsqu'un crochet de serrure à été déplacé en position d'ouverture, la serrure reste dans cette position aussi longtemps que le crochet n'a pas été, à nouveau, replacé dans sa position de fermeture. On peut dès lors ouvrir une des serrures, retirer la clef puis ouvrir l'autre serrure, retirer la clef et basculer le couvercle vers le haut sans problèmes.They must be provided with locking means using locks, which are generally in number of two, arranged on a lateral side of the boot lid. As the safes are generally elongated, the locks are therefore quite distant from each other. At the beginning, these locks were provided with hooks actuated by the cylinder or barrel of the lock using a key. When a lock hook has been moved to the open position, the lock remains in this position as long as the hook has not been returned to its closed position again. We can therefore open one of the locks, remove the key then open the other lock, remove the key and tilt the cover up without problems.
Toutefois, en refermant le couvercle, les serrures se trouvent toujours en position ouverte et le risque existe donc qu'on oublie de refermer les serrures afin d'éviter toute ouverture non autorisée ou intempestive du couvercle. Afin de remédier à cet inconvénient, ont à développé des serrures qui se referment automatiquement lorsque le couvercle du coffre est rabattu en position fermée.However, by closing the cover, the locks are always in the open position and there is therefore a risk that one forgets to close the locks in order to avoid any unauthorized or untimely opening of the cover. To overcome this drawback, have developed locks that close automatically when the trunk lid is folded down to the closed position.
Ce genre de serrures automatiques, comprennent généralement deux cames à crochet disposées symétriquement par rapport à l'axe du cylindre de la serrure.This kind of automatic locks, generally comprise two hook cams arranged symmetrically with respect to the axis of the cylinder of the lock.
Les crochets sont disposés aux extrémités des cames et sont normalement maintenus, à l'aide d'un ressort, dans une position écartée, c'est à dire, en position de fermeture coopérant avec une pièce de retenu de la partie fixe du coffre.The hooks are arranged at the ends of the cams and are normally held, by means of a spring, in a separated position, that is to say, in the closed position cooperating with a retaining part of the fixed part of the boot.
Toutefois, du fait que les serrures sont assez éloignées l'une de l'autre, et que le couvercle est généralement très flexible, le danger existe que, lorsqu'on a ouvert la serrure du côté avant, et retiré la clé pour ouvrir la serrure du côté arrière, la serrure du côté avant se referme automatiquement et vise versa.However, since the locks are quite far apart and the cover is generally very flexible, there is a danger that when the lock is opened on the front side and the key is removed to open the lock rear side lock, the front side lock closes automatically and aims vice versa.
Ceci oblige l'utilisateur de maintenir le couvercle en position ouverte avec une main, pendant qu'il ouvre l'autre serrure de l'autre main ce que n'est pas toujours facile et confortable, surtout lorsque les serrures sont fort éloignées l'une de l'autre. La serrure selon l'invention vise à remédier à cet inconvénient par des moyens simples et efficaces incorporés dans chaque serrure.This forces the user to hold the cover in the open position with one hand, while he opens the other lock with the other hand, which is not always easy and comfortable, especially when the locks are far apart. one of the other. The lock according to the invention aims to remedy this drawback by simple and effective means incorporated in each lock.
Le but de la présente invention réside donc dans la réalisation d'une serrure munie de moyens pour maintenir les crochets en position d'ouverture même lorsqu'on a ramené le barillet ou cylindre dans la position de fermeture pour retirer la clé de la serrure.The object of the present invention therefore lies in the production of a lock provided with means for holding the hooks in the open position even when the barrel or cylinder has been brought back to the closed position in order to remove the key from the lock.
Un deuxième but de l'invention est de prévoir des moyens pour maintenir écarté l'ensemble du couvercle avec la serrure par rapport à la partie inférieur du coffre. Un troisième but de l'invention est de prévoir, en cas de serrure avec cylindre retirable, des moyens permettant de retenir le cylindre en position de fermeture du coffre.A second object of the invention is to provide means for keeping the entire cover apart with the lock relative to the lower part of the trunk. A third object of the invention is to provide, in the event of a lock with a removable cylinder, means making it possible to retain the cylinder in the closed position of the trunk.
Afin de réaliser ces buts, la serrure, objet de l'invention, est munie de moyens telles que décrit dans les revendications. D'autres caractéristiques et avantages de l'invention ressortiront de la description d'exemples de réalisations pratiques de l'invention et à l'aide des dessins annexés dans lesquels : la figure 1 : montre une vue en explosé du dessous des composants de la serrure selon l'invention et d'une pièce métallique de fermeture solidaire de la partie fixe du coffre; la figure l a : montre une vue de la serrure montée en position de fermeture par rapport à la pièce métallique de la partie fixe du coffre; la figure 2 : montre la serrure en position fermée du coffre; la figure 3 : montre la serrure en position ouverte du coffre avec le cylindre en position ouverte - clé non retirable; la figure 4 : montre la serrure en position ouverte du coffre avec le cylindre ramené dans sa position initiale (de fermeture) - la clé pouvant être retirée; la figure 5 : montre une variante de réalisation d'une serrure avec cylindre retirable selon l'invention, celle-ci étant en position de fermeture du coffre; la figure 5a : montre une vue en coupe selon la ligne A-A dans la figure 5 ; la figure 6 : montre la même serrure selon la figure 5 mais en position d'ouverture du coffre, le cylindre de la serrure étant ramené dans sa position initiale (de fermeture). la figure 6a : montre une vue en coupe selon la ligne A-A dans la figure 6.In order to achieve these aims, the lock, object of the invention, is provided with means as described in the claims. Other characteristics and advantages of the invention will emerge from the description of examples of practical embodiments of the invention and with the aid of the appended drawings in which: FIG. 1: shows an exploded view from below of the components of the lock according to the invention and a metal closure piece secured to the fixed part of the trunk; Figure la: shows a view of the lock mounted in the closed position relative to the metal part of the fixed part of the trunk; Figure 2: shows the lock in the closed position of the trunk; Figure 3: shows the lock in the open position of the trunk with the cylinder in the open position - key not removable; Figure 4: shows the lock in the open position of the trunk with the cylinder returned to its initial (closed) position - the key can be removed; Figure 5: shows an alternative embodiment of a lock with removable cylinder according to the invention, the latter being in the closed position of the trunk; Figure 5a: shows a sectional view along line AA in Figure 5; Figure 6: shows the same lock according to Figure 5 but in the boot open position, the cylinder of the lock being returned to its initial position (closed). FIG. 6a: shows a sectional view along the line AA in FIG. 6.
Comme montré à la figure 1 , la serrure selon l'invention comprend un support 10 pourvu d'une pièce centrale tubulaire 12 destinée à recevoir le barillet ou cylindre 14 muni de paillettes 16, pouvant être actionner par une clé 18 prévu à cet effet, et d'un embout 19 à son extrémité arrière.As shown in FIG. 1, the lock according to the invention comprises a support 10 provided with a tubular central part 12 intended to receive the barrel or cylinder 14 provided with flakes 16, which can be actuated by a key 18 provided for this purpose, and a nozzle 19 at its rear end.
De part et d'autre de la pièce centrale tubulaire 12, le support 10 est munie d'ailettes 20 de fixation, par exemple, au bord latéral du couvercle d'un coffre ou boîte à bagages (non représenté).On either side of the central tubular part 12, the support 10 is provided with fins 20 for fixing, for example, to the lateral edge of the lid of a trunk or luggage box (not shown).
Le support 10 comprend également une patte 22 qui s'étend vers le bas et qui sert de support d'appui et de guidage pour les cames 24 munies de crochets 26 à leurs extrémités inférieures. L'extrémité inférieure de la patte 22 est de forme légèrement conique afin de faciliter l'introduction et d'obtenir un auto-centrage de la serrure par rapport à l'ouverture 46 de la pièce de verrouillage 48 solidaire de la partie fixe du coffre. Chaque came 24 présente, à son côté extérieur, une encocheThe support 10 also includes a tab 22 which extends downwards and which serves as a support and guide support for the cams 24 provided with hooks 26 at their lower ends. The end lower of the tab 22 is of slightly conical shape in order to facilitate the introduction and to obtain self-centering of the lock with respect to the opening 46 of the locking piece 48 secured to the fixed part of the boot. Each cam 24 has, on its outer side, a notch
28 coopérant avec un pivot 30 solidaire du support 10 et les cames 24 sont normalement maintenues en position écartée à l'aide d'un ressort 32 logé dans des découpes 34 prévues du côté intérieur des cames 24.28 cooperating with a pivot 30 secured to the support 10 and the cams 24 are normally held in the separated position by means of a spring 32 housed in cutouts 34 provided on the inside of the cams 24.
Les deux extrémités supérieures 36 des cames 24 peuvent coopérer avec l'embout arrière 19 du cylindre 14.The two upper ends 36 of the cams 24 can cooperate with the rear end piece 19 of the cylinder 14.
Le mécanisme de la serrure est fermé par un boîtier 40, rendu solidaire du support 10 et qui est pourvu de deux logements 42 pour les pivots 30 des cames 24.The lock mechanism is closed by a housing 40, made integral with the support 10 and which is provided with two housings 42 for the pivots 30 of the cams 24.
Les crochets 26 des cames 24 peuvent coopérer avec des replis 44 d'une découpe 46 prévue dans une pièce métallique 48 solidaire de la partie fixe (non illustrée) du coffre ou de la boîte, comme on peut le voir sur la figure l a montrant la serrure assemblée en position de fermeture du coffre.The hooks 26 of the cams 24 can cooperate with folds 44 of a cutout 46 provided in a metal part 48 secured to the fixed part (not shown) of the trunk or of the box, as can be seen in the figure showing the assembled lock in the boot closed position.
Conformément à l'invention, une pièce coulissante 50 est prévue à l'intérieur du boîtier 40. Cette pièce coulissante 50 présente la forme d'un cavalier dont les deux jambes 52 peuvent s'étendre vers le bas au travers d'ouvertures 54 prévues dans le boîtier 40.According to the invention, a sliding part 50 is provided inside the housing 40. This sliding part 50 has the shape of a jumper, the two legs 52 of which can extend downwards through openings 54 provided in the housing 40.
L'extrémité inférieure des jambes 52 est maintenue en contact avec la pièce métallique 48 fixe à l'aide de ressorts 56 qui s'appuient contre la paroi supérieure du boîtier 40, d'une part et sur la traverse supérieure 58 de la pièce coulissant 50 d'autre part. Ce contact est possible dans les limites de déplacement de la pièce coulissante 50 à l'intérieure du boîtier 40. La traverse supérieure 58 est munie, à son côté inférieur de deux saillies 60 dont le but sera expliqué dans la description du fonctionnement de la serrure.The lower end of the legs 52 is kept in contact with the fixed metal part 48 by means of springs 56 which bear against the upper wall of the housing 40, on the one hand and on the upper crosspiece 58 of the sliding part 50 on the other hand. This contact is possible within the displacement limits of the sliding part 50 inside the housing 40. The upper cross member 58 is provided, at its lower side with two projections 60 whose purpose will be explained in the description of the operation of the lock .
La pièce coulissante 50 peut également être pourvue d'une entretoise 62, en forme de V, dont l'extrémité inférieure est munie d'un crochet 64. La nécessité de cette entretoise 62 avec crochet 64 sera expliqué ci-après lors de la description d'une variante de réalisation à l'aide des figures 5 et 6. Le fonctionnement d'une serrure selon l'invention sera expliqué ci-après à l'aide des figures 2 à 4.The sliding part 50 can also be provided with a spacer 62, in the form of a V, the lower end of which is provided with a hook 64. The need for this spacer 62 with hook 64 will be explained below during the description of an alternative embodiment using FIGS. 5 and 6. The operation of a lock according to the invention will be explained below using FIGS. 2 to 4.
Sur la figure 2, la serrure est montrée dans la position de fermeture. Le couvercle du coffre, solidaire de la serrure, est donc verrouillé avec la pièce métallique 48, solidaire de la partie inférieure fixe du coffre.In Figure 2, the lock is shown in the closed position. The trunk lid, secured to the lock, is therefore locked with the metal part 48, secured to the fixed lower part of the trunk.
Dans cette position, l'embout 19 du cylindre 14, se trouve en position verticale et les extrémités 36 des cames s'appuient contre les faces allongées de l'embout sous l'effet du ressort 32 qui maintien également les crochets 26 des cames 24 en position écartés et en prise avec les replis 44 de la pièce métallique fixe 48.In this position, the end piece 19 of the cylinder 14 is in a vertical position and the ends 36 of the cams bear against the elongated faces of the end piece under the effect of the spring 32 which also holds the hooks 26 of the cams 24 in the separated position and in engagement with the folds 44 of the fixed metal part 48.
La pièce coulissante 50 se trouve dans une position entrée dans le boîtier 40 et les ressorts 56 sont complètement enfoncés.The sliding part 50 is in a position entered into the housing 40 and the springs 56 are fully inserted.
Lorsqu'on désire ouvrir le coffre, le cylindre 14 et son embout 19 sont mis en rotation à l'aide d'une clé 1 8 adéquate pour atteindre la position d'ouverture montrée à la figure 3.When it is desired to open the boot, the cylinder 14 and its end piece 19 are rotated using a suitable key 1 8 to reach the open position shown in FIG. 3.
Dans cette position on constate que les cames 24 ont été basculées autour des pivots 30 par l'action de l'embout 19 sur les extrémités 36 des cames 24 et ce à l'encontre de l'action du ressort 32. Par ce basculement des cames 24, les crochets 26 se sont retirés de l'emprise sur les replis 44 de la pièce métallique 48 et la serrure est repoussée légèrement vers le haut par la pièce coulissante 50 grâce à l'action des ressorts 56. Dans cette position, la partie du couvercle du coffre située à proximité de la serrure peut être librement soulevé.In this position, it can be seen that the cams 24 have been tilted around the pivots 30 by the action of the end piece 19 on the ends 36 of the cams 24 and this against the action of the spring 32. By this tilting of the cams 24, the hooks 26 are withdrawn from the grip on the folds 44 of the metal part 48 and the lock is pushed slightly upwards by the sliding part 50 thanks to the action of the springs 56. In this position, the part of the trunk lid located near the lock can be freely lifted.
Toutefois, pour ouvrir la deuxième serrure à l'autre extrémité du coffre on doit retirer la clé 18 de la première serrure, ce qui peut se faire en ramenant le cylindre 14 dans la position fermée de la figure 1. Cette position est représentée à la figure 4. En effet, on constate que l'embout 19 est revenu à la position verticale. Toutefois, grâce à la serrure selon l'invention, les cames 24 restent bloquées par leurs extrémités 36 derrière les saillies 60 de la pièce coulissante 50 lorsque celle-ci se trouve en position sortie du boîtier 40. L'utilisateur peut dès lors ouvrir la deuxième serrure de la même façon que la première, sans risque que la première serrure se referme sous l'action des crochets 26 dans l'ouverture 46 de la pièce métallique 48.However, to open the second lock at the other end of the trunk, the key 18 must be removed from the first lock, which can be done by returning the cylinder 14 to the closed position in FIG. 1. This position is shown in Figure 4. Indeed, we see that the tip 19 is returned to the vertical position. However, thanks to the lock according to the invention, the cams 24 remain blocked by their ends 36 behind the projections 60 of the sliding part 50 when the latter is in the extended position of the housing 40. The user can therefore open the second lock in the same way as the first, without risk that the first lock will closes under the action of the hooks 26 in the opening 46 of the metal part 48.
Aussi longtemps que les jambes 52 de la pièce coulissanteAs long as the legs 52 of the sliding part
50 sont en position sortie (figures 3 et 4) il n'y a donc aucun risque que la serrure se referme automatiquement. Il faut dès lors que la capacité des ressorts (56) soit suffisante pour supporter le poids du couvercle à proximité de la serrure.50 are in the extended position (Figures 3 and 4) so there is no risk that the lock will close automatically. It is therefore necessary that the capacity of the springs (56) is sufficient to support the weight of the cover near the lock.
Pour fermer le couvercle du coffre, il suffit dès lors de pousser le couvercle à proximité d'une serrure vers le bas pour faire rentrer les jambes 52 de la pièce coulissante 50 à l'encontre des ressorts 56 pour supprimer l'emprise des saillies 60 sur les extrémités 36 des cames 24. A ce moment, les crochets 26 vont à nouveau basculer vers l'extérieur pour venir se verrouiller à l'intérieur de la découpe 46 de la pièce métallique 48. Le risque de fermeture accidentelle est par conséquent éliminé.To close the trunk lid, it is therefore sufficient to push the lid near a lock down to bring in the legs 52 of the sliding part 50 against the springs 56 to remove the grip of the projections 60 on the ends 36 of the cams 24. At this moment, the hooks 26 will again tilt outwards to come and lock themselves inside the cutout 46 of the metal part 48. The risk of accidental closing is therefore eliminated .
Un autre avantage de cette serrure selon l'invention, est que la pièce coulissante 50, qui sera réalisé avantageusement en matière plastique, est toujours en contact avec la pièce métallique 48 en position de fermeture du coffre, donc également lorsque le véhicule se déplace. Grâce aux ressorts 56, qui exercent toujours une pression entre le boîtier 40 de la serrure et la partie fixe du coffre, on évite tout problèmes de bruits dûs aux vibrations.Another advantage of this lock according to the invention is that the sliding part 50, which will advantageously be made of plastic, is always in contact with the metal part 48 in the closed position of the boot, therefore also when the vehicle is moving. Thanks to the springs 56, which always exert pressure between the housing 40 of the lock and the fixed part of the boot, noise problems due to vibrations are avoided.
Les jambes 52 jouent donc également un rôle d'amortisseur de chocs en éliminant tous les bruits possibles pouvant provenir de contacts éventuelles entre le support de la serrure et la pièce métallique 48. La pièce coulissante 50 peut également être réalisée en toute autre matériau ayant un coefficient de dureté inférieur à celui de l'acier.The legs 52 therefore also play a role of shock absorber by eliminating all the possible noises which can come from possible contacts between the support of the lock and the metal part 48. The sliding part 50 can also be made of any other material having a lower hardness coefficient than steel.
Lorsque qu'on veut équiper la serrure selon l'invention avec un cylindre ou barillet retirable, tel que décrit dans le brevet BE 8800736 ou le brevet EP 0 350 474 au nom de la demanderesse, il faut prévoir des moyens qui retiennent le cylindre lorsque le coffre et les serrures sont en position de fermeture. Ce n'est que lorsque le coffre est ouvert avec le couvercle du coffre légèrement soulevé, avec les jambes 52 de la pièce coulissante 50 en position sortie, que le cylindre peut être retiré. Ce problème est résolu grâce à une variante de réalisation de la pièce coulissante 50. En effet, comme déjà montré à la figure 1 , la pièce coulissante 50 est, à cet effet, munie d'une entretoise 62 en forme de N avec dans la partie inférieure un crochet 64 de retenu de l'embout 19.When it is desired to equip the lock according to the invention with a removable cylinder or barrel, as described in patent BE 8800736 or patent EP 0 350 474 in the name of the applicant, means must be provided which retain the cylinder when the trunk and the locks are in the closed position. It is only when the trunk is opened with the trunk lid slightly raised, with the legs 52 of the sliding part 50 in the extended position, that the cylinder can be removed. This problem is solved by an alternative embodiment of the sliding part 50. In fact, as already shown in FIG. 1, the sliding part 50 is, for this purpose, provided with an N-shaped spacer 62 with in the lower part a hook 64 for retaining the end piece 19.
Cette réalisation est montrée à l'aide des figures 5, 5a, 6 et 6a.This embodiment is shown using FIGS. 5, 5a, 6 and 6a.
La figure 5 montre la serrure dans une position équivalente de la figure 2, c.a.d. avec la serrure et le couvercle du coffre dans la position fermée. A part les composants identiques à la figure 2, on distingue l'entretoise 62 de la pièce coulissante 50. L'entretoise présente une forme de V et s'étend jusqu'en dessous de l'embout 19 du cylindre retirable 15.Figure 5 shows the lock in an equivalent position of Figure 2, i.e. with the lock and the trunk lid in the closed position. Apart from the components identical to FIG. 2, a distinction is made between the spacer 62 and the sliding part 50. The spacer has a V shape and extends to below the end piece 19 of the removable cylinder 15.
La partie inférieure de cette entretoise 52 est pourvue d'un crochet de retenu 64. Comme on peut le voir sur la figure 5a, ce crochet 64 est logé dans une gorge prévue derrière l'embout 19. On comprendra aisément que le cylindre 15 ne peut être retiré dans cette position là.The lower part of this spacer 52 is provided with a retaining hook 64. As can be seen in FIG. 5a, this hook 64 is housed in a groove provided behind the end piece 19. It will be readily understood that the cylinder 15 does not can be removed in this position there.
Lorsque la serrure a été ouverte et le couvercle du coffre légèrement soulevé, on peut, tout comme représenté à la figure 4, ramener le cylindre 15 dans la position verticale afin de retirer la clé d'ouverture normale.When the lock has been opened and the trunk lid slightly raised, it is possible, as shown in FIG. 4, to return the cylinder 15 to the vertical position in order to remove the normal opening key.
A ce moment, et comme représenté aux figures 6 et 6a, on peut utiliser la clé spéciale destinée à retirer le cylindre retirable 15 de la pièce centrale tubulaire 12 de la serrure. En effet, cette clé spéciale permet d'abaisser le cavalier de retenu 17 de ce cylindre qui est normalement en prise avec un rebord intérieure de la pièce centrale tubulaire 12.At this time, and as shown in Figures 6 and 6a, one can use the special key to remove the removable cylinder 15 of the central tubular part 12 of the lock. In fact, this special key makes it possible to lower the retaining rider 17 of this cylinder which is normally engaged with an inner rim of the central tubular part 12.
Etant donné que la pièce coulissante 50 est descendue, en sortant du boîtier 40, le crochet 64 libère l'embout 19 du cylindre retirable 15 et celui-ci peut, dès lors, librement sortir de la serrure.Since the sliding part 50 is lowered, leaving the housing 40, the hook 64 releases the end piece 19 of the removable cylinder 15 and the latter can, therefore, freely come out of the lock.
Bien sûr, d'autres formes de réalisations de la serrure restent possibles sans pour autant sortir du cadre de la présente invention Légende des figures :Of course, other embodiments of the lock remain possible without departing from the scope of the present invention Legend of figures:
