Description

DESCRIPTION DE L'INVENTION DESCRIPTION OF THE INVENTION
Perfectionnements apportés aux serrures à gage tels que consigneursImprovements to pawned locks such as lockers
La présente invention concerne des perfectionnements apportés aux serrures à gage, tels que consigneurs, notam¬ ment pour chariots de manutention.The present invention relates to improvements made to pledge locks, such as depositors, in particular for handling carts.
L'invention vise plus spécialement les serrures du type comportant une clé d'attache susceptible d'être rendu temporairement prisonnière de la serrure tant qu'une pièce de monnaie n'a pas été engagée dans la dite serrure. L'invention concerne encore, les serrures du genre en question dont la clé se présente sous forme d'une pièce de révolution à profil axial symétrique.The invention relates more specifically to locks of the type comprising a fastening key capable of being temporarily trapped in the lock as long as a coin has not been engaged in said lock. The invention also relates to locks of the kind in question, the key of which is in the form of a part of revolution with a symmetrical axial profile.
Il existe plusieurs genres de serrure sur le marché se présentant sous forme de boitiers relativement volumineux installés le plus souvent sur la barre de conduite des chariots de manutention. Ces serrures permettent, de par leur volume d'intégrer des sécurités anti-vandalisme, mais leur encombrement est un handicap. Aussi on a vu apparaî¬ tre sur le marché une seconde génération de serrures de faible encombrement mais beaucoup moins sûres contre le vandalisme et spécialement vulnérables à la récupération non autorisée de la pièce de monnaie, soit en forçant l'ouverture de la dite pièce qui reste partiellement visible pendant l'utilisation des chariots, soit encore en introduisant dans le passage de clé un objet quelconque non autorisé. La présente invention a en conséquence pour but de fournir une serrure à gage d'un nouveau type, qui réponde mieux aux exigences des gestionnaires de parc de chariots et qui garantisse aussi les utilisateurs contre les tentatives de récupérations non autorisées de pièces de monnaie gagées dans les serrures-consigne.There are several types of locks on the market in the form of relatively large boxes installed most often on the conduct bar of industrial trucks. These locks allow, by their volume to integrate anti-vandalism security, but their size is a handicap. Also we have seen appear on the market a second generation of locks of small size but much less secure against vandalism and especially vulnerable to unauthorized recovery of the coin, or by forcing the opening of said coin which remains partially visible during the use of the carts, or by introducing any unauthorized object into the key passage. The object of the present invention is therefore to provide a new type of lock which better meets the requirements of fleet managers and which also guarantees users against attempts to recover unauthorized coins pledged in locks.
L'invention a en conséquence pour but une serrure à gage de faible encombrement dotée d'un mécanisme de sécurité tant côté entrée des pièces de monnaie que du côté entrée clé d'attache, ce mécanisme comprenant un minimum de pièces mécaniques simples permettant de préférence, mais non exclusivement 1 ' emploi des techniques de moulage des matières plastiques.The object of the invention is therefore to provide a compact lock with a security mechanism both on the coin entry side and on the attachment key entry side, this mechanism comprising a minimum of simple mechanical parts, preferably allowing , but not exclusively the use of plastic molding techniques.
L'invention concerne à cet effet une serrure à gage, notamment pour chariots de manutention, du type comportant une clé d'attache temporairement prisonnière de la serrure tant qu'une pièce de monnaie n'est pas engagée dans la dite serrure, cette clé se présentant sous forme d'une pièce de révolution à profil axial symétrique, serrure caractérisée en ce qu'elle comporte un mécanisme constitué principalement d'un levier pivotant à deux bras coopérant côté entrée de pièce de monnaie avec un chariot coulis¬ sant permettant de conserver la pièce de monnaie à 1'in¬ térieur du corps de serrure et coopérant côté entrée de clé d'attache avec une g chette qui, pour une position axiale, emprisonne la clé d'attache dans le corps de serrure et pour une autre position autorise l'entrée du passage de la clé d'attache. Suivant une disposition, la g chette actionnée axialement par le levier pivotant coopère avec une paire de verrous à déplacement radial par rapport à l'axe d'introduction de clé d'attache, les dits verrous pouvant occuper deux positions, l'une rapprochée de l'axe d'introduction de la clé lorsque cette dernière est hors du corps de serrure pour obturer le passage de clé, l'autre, éloignée du dit axe sous l'action du profil de la clé lorsqu'elle est introduite dans la serrure.To this end, the invention relates to a hired lock, in particular for handling carts, of the type comprising an attachment key temporarily trapped in the lock as long as a coin is not engaged in said lock, this key in the form of a part of revolution with a symmetrical axial profile, lock characterized in that it comprises a mechanism constituted mainly of a pivoting lever with two arms cooperating on the coin entry side with a sliding carriage making it possible to keep the coin inside the lock body and cooperating on the attachment key entry side with a g chette which, for an axial position, traps the attachment key in the lock body and for another position allows entry of the passage of the attachment key. According to one arrangement, the lever actuated axially by the pivoting lever cooperates with a pair of latches with radial displacement relative to the axis of insertion of the attachment key, the said latches being able to occupy two positions, one close to the key insertion axis when the latter is outside the lock body to close the key passage, the other, distant from said axis under the action of the key profile when it is inserted into the lock .
D'autres caractéristiques et avantages apparaîtront encore à la lecture de la description détaillée qui suit, d'un mode de réalisation de la serrure perfectionnée, donné ici à titre d'exemple et représentée sur les dessins joints dans lesquels :Other characteristics and advantages will become apparent on reading the detailed description which follows, of an embodiment of the improved lock, given here by way of example and shown in the accompanying drawings in which:

Suivant l'invention, ainsi que représentée aux dessins annexes, la serrure à gage est désignée par la référence générale 10. La serrure se compose d'un corps de serrure principal 11 contenant le mécanisme de serrure, ce corps étant coiffé d'un boitier de fermeture inviolable 12. Le corps de serrure comporte sur l'une de ses faces fron¬ tale 13 un passage 14 pour une pièce de monnaie 15. L'autre face frontale 16 comporte une ouverture 17 pour l'introduction d'une clé d'attache 18. Selon une disposi¬ tion particulière, la clé 18 se présente sous forme d'un corps de révolution interrompu par au moins une gorge 19 disposée derrière un cylindre écarteur 20 dont le rôle sera décrit plus loin. La clé 18 se termine côté serrure par une extrémité distale 21. Les cylindres 20 et 20a de la clé se raccordent à l'axe de clé 22 par des cônes de révolution respectivement 23-24 agissant sur les verrous de la serrure pour autoriser l'introduction de la clé dans le sens de son introduction dans le corps de la serrure. Le corps de révolution 20 de la clé 18 possède, à l'opposé du cône de révolution 23 une face plane 25 qui s'oppose au retrait de la clé en position dite de verrouillage de la clé dans le corps de serrure. Le mécanisme de la serrure est constitué principalement d'un levier pivotant 26 bien visible figure 2 à deux bras respectivement 27-28. Le bras 27 est prolongé d'un talon 29 qui sert à emprisonner la pièce de monnaie 15 lors¬ qu'elle est introduite dans le corps de serrure. Le levier à deux bras se présente sous la forme générale d'une équerre déplaçable angulairement autour d'un axe pivot 30. La branche 27 du levier à deux bras est disposée le long du côté latéral lia du corps de serrure. La seconde branche 28 du levier 26 est, pour une position angulaire du dit levier, perpendiculaire au côté latéral lia du corps de serrure. L'extrémité de la branche 27 du levier à deux bras est cinématiquement solidaire d'une gâchette 31 déplaçable axialement entre les parois latérales du corps de serrure et perpendiculairement à ces dernières, entre deux positions, l'une dans laquelle la gâchette emprisonne la clé d'attache à l'intérieur du corps de serrure, l'autre dans laquelle elle permet le libre pas¬ sage à la dite clé, soit pour son introduction, soit pour son retrait. La gâchette 31 se présente sous forme d'une pièce parallé- lipipédique plate avec un orifice circulaire 32 prolongé par une boutonnière étroite 33 pouvant prendre place dans 1 'échancrure 19 de la clé d'attache. La gâchette 31 coopère avec une paire de verrous, respectivement 33-34 à déplacement radial par rapport à l'axe d'introduction de la clé d'attache 18. Les verrous, chargés par ressorts 35-36 peuvent occuper deux positions, l'une rapprochée de l'axe d'introduction de la clé d'attache lorsque cette dernière est hors du corps de serrure obstruant ainsi le passage 17 de clé ce qui interdit l'accès au mécanisme par toutes sortes d'objets non autorisés. Dans l'autre position, éloignée par rapport à l'axe d'introduction de la clé d'attache sous l'action du profil de la clé en particulier sous l'action de la section cylindrique 20. Chaque verrou 33-34 possède un talon 33a qui, dans la position rapprochée de l'axe d'introduction de la clé d'attache immobilisent les mouvements axiaux de la g⬠chette 31 et par suite le mouvement de pivotement du levier à deux bras 26 lorsqu'une pièce de monnaie 15 est introduite dans le corps de serrure. On comprend que par cette disposition on ne peut pas récupérer la dite pièce de monnaie, sauf si l'on utilise la clé autorisée qui libère les verrous 33-34. Il est prévu, côté entrée de pièce de monnaie du corps de serrure un chariot porte pièce 37 dont le calibre 38 est adapté aux différents diamètres des pièces de monnaie. Le chariot possède dans sa partie médiane un talon 39 en appui sur la branche 28 du levier à deux bras pour actionner ce dernier lorsque le chariot est poussé à l'intérieur du corps de serrure par l'action d'introduction d'une pièce de monnaie. Il est prévu, dans le corps de serrure, côté entrée de pièce de monnaie un boitier 39 à coulissement axial dans un guide stationnaire 40. Le boitier coulissant 39 possède un piston 41 chargé par ressort 42 et sur lequel vient prendre appui l'extrémité distale 21 de la clé 18. Le boitier 39 possède un taquet 39a qui vient en prise par contact avec la seconde branche 28 du levier 26. Ce dis¬ positif, une fois armé par l'introduction de la clé 18 permet, lors de l'introduction d'une pièce de monnaie d'éjecter la clé d'attache hors du corps de serrure par décompression du ressort 42. Le boitier 12 de fermeture du corps de serrure est équipé d'un verrou 43 à déplace¬ ment radial en direction de 1' xe d'introduction de la clé d'attache. Le verrou coopère avec le chariot porte pièce 37 de manière à immobiliser ce dernier par l'inter¬ médiaire des taquets 44 effaçable lorsque 1'on introduit une pièce de monnaie dans le corps de serrure. According to the invention, as shown in the accompanying drawings, the token lock is designated by the general reference 10. The lock consists of a main lock body 11 containing the lock mechanism, this body being capped with a housing tamper-evident closure 12. The lock body has on one of its front faces 13 a passage 14 for a coin 15. The other front face 16 has an opening 17 for the introduction of a key d 'fastener 18. According to a particular arrangement, the key 18 is in the form of a body of revolution interrupted by at least one groove 19 disposed behind a spacer cylinder 20 whose role will be described below. The key 18 ends on the lock side with a distal end 21. The cylinders 20 and 20a of the key are connected to the key axis 22 by cones of revolution respectively 23-24 acting on the locks of the lock to authorize the introduction of the key in the direction of its introduction into the body of the lock. The body of revolution 20 of the key 18 has, opposite the cone of revolution 23 a flat face 25 which opposes the withdrawal of the key in the so-called key locking position in the lock body. The lock mechanism consists mainly of a pivoting lever 26 clearly visible in Figure 2 with two arms 27-28 respectively. The arm 27 is extended by a heel 29 which is used to trap the coin 15 when it is introduced into the lock body. The lever with two arms is in the general form of a square which can be displaced angularly about a pivot axis 30. The branch 27 of the lever with two arms is arranged along the lateral side 11a of the lock body. The second branch 28 of the lever 26 is, for an angular position of the said lever, perpendicular to the lateral side 11a of the lock body. The end of the branch 27 of the lever with two arms is kinematically integral with a trigger 31 movable axially between the side walls of the lock body and perpendicular to the latter, between two positions, one in which the trigger traps the key of attachment inside the lock body, the other in which it allows the free passage of said key, either for its introduction or for its removal. The trigger 31 is in the form of a flat parallelipiped part with a circular orifice 32 extended by a narrow buttonhole 33 which can take place in one notch 19 of the attachment key. The trigger 31 cooperates with a pair of latches, respectively 33-34 with radial displacement relative to the axis of introduction of the attachment key 18. The latches, loaded by springs 35-36 can occupy two positions, the approximation of the axis of introduction of the attachment key when the latter is outside the lock body thus obstructing the passage 17 of the key which prevents access to the mechanism by all kinds of unauthorized objects. In the other position, distant from the axis of introduction of the attachment key under the action of the profile of the key in particular under the action of the cylindrical section 20. Each lock 33-34 has a heel 33a which, in the position close to the axis of introduction of the attachment key immobilizes the axial movements of the trigger 31 and consequently the pivoting movement of the lever with two arms 26 when a coin 15 is introduced into the lock body. We understand that by this provision we can not recover said coin, unless we use the authorized key which releases the locks 33-34. On the coin entry side of the lock body, a coin carriage 37 is provided, the size 38 of which is adapted to the different diameters of the coins. The carriage has in its middle part a heel 39 bearing on the branch 28 of the lever with two arms to actuate the latter when the carriage is pushed inside the lock body by the action of introducing a coin. There is provided, in the lock body, on the coin entry side, a housing 39 with axial sliding in a stationary guide 40. The sliding housing 39 has a piston 41 loaded by spring 42 and on which the distal end comes to bear. 21 of the key 18. The housing 39 has a cleat 39a which comes into contact with the second branch 28 of the lever 26. This device, once armed by the introduction of the key 18 allows, during the introduction of a coin to eject the attachment key out of the lock body by decompression of the spring 42. The housing 12 for closing the lock body is equipped with a lock 43 with radial displacement in the direction of 1 x introduction of the attachment key. The lock cooperates with the workpiece carrier carriage 37 so as to immobilize the latter by means of the erasable lugs 44 when a coin is introduced into the lock body.
