Definitions

  • the invention relates to a coin deposit system, in particular a coin deposit lock for use in shopping trolleys.
  • the empty shopping trolley is brought to the designated shopping trolley row and inserted into this row, the key that is firmly connected to the next shopping trolley can be re-entered into the coin deposit lock in reverse order and the inserted coin becomes again Removal released.
  • Another objective is to design the coin deposit lock so that a common version for all coin pieces in practical use is possible, so that a certain range of coin types is permitted, so that the same type coin deposit lock is available almost worldwide without modifications to the respective national coin system can be used.
  • At least the coin chamber and key chamber are matched to one another essentially exclusively by the inner contour of the housing on the one hand and the outer contours of the functional parts on the other hand such that at least one functional part in each case in its associated chamber is freely movable between a locking position and a release position.
  • the basic idea of the invention is, first of all, that the number of components used is minimized by these components not only fulfilling their original function (e.g. as housing components), but also, due to their respective inner contours or outer contours, the movements within the coin deposit lock between the Control the locking position and the release position independently, in particular avoiding expensive axle bearings for rotating or swiveling movements.
  • this solution enables, for example, a sandwich-like construction of the coin deposit lock from three layers, the middle layer containing the functional components and the top and bottom layer serving as a cover.
  • the middle layer containing the functional components and the top and bottom layer serving as a cover.
  • guide grooves for example elongated holes, are introduced in the bottom or top of the housing and engage in the corresponding pins of the functional components, so that the possible movements of the functional components and the control bolt between their respective movements are hereby made in the simplest possible way Locking positions and their release position can be defined.
  • Such grooves, on the one hand, or guide pins, on the other hand, are also very easy to manufacture in terms of production technology, since they can be integrated into the respective components directly during manufacture, for example by appropriate casting, stamping or integral molding.
  • FIG. 1 a top view of the first, preferred embodiment of a coin deposit lock according to the invention, with the top cover removed,
  • FIG. 2 shows a cross section through the coin deposit lock according to FIG. 1 in the plane II-II of FIG. 1 with the top cover attached,
  • FIGS. 1 and 2 shows a perspective view of the coin deposit lock of FIGS. 1 and 2 with the top cover removed in its position with the coin locked and the key released,
  • FIG. 4 shows a perspective illustration according to FIG. 3, but with the coin released and the key locked

  • the lower cover 102 which is thus visible in FIG. 1, is shown with horizontal hatching.
  • the lower cover 102 consists of an essentially rectangular plastic plate, into which grooves N are made at certain points, the function of which will be explained further below.
  • This lower cover 102 is used to receive two profile parts 103A, 103B, which form the side walls of the housing 10 and are aligned on the long sides with the two covers 101, 102.
  • Each of the functional parts 21, 22, 31 and 32 are inserted into the trough-like housing structure formed by the lower cover 102 and the two lateral profile parts 103A, 103B, and a control bolt 40, in such a way that guide pins Z on these components fit into the associated ones Immerse the grooves N so that certain movement sequences of the components within the housing on the lower cover 102 are thus defined or the boundary conditions for such movement sequences are specified.
  • Each of the functional parts 21... 32 and the control bolt 40 each have two guide pins Z, which engage in corresponding grooves N in the lower cover 102, as can be seen particularly clearly in FIG. 1.
  • control bolt 40 can be displaced between its two end positions (coin inserted or key inserted) in the direction of the double arrow P in its slot N, which is designed as an elongated hole, and that during this displacement the control bolt 40 with its The outer contour acts on the inward-pointing contours of the functional parts 21, 22, 31 and 32, so that they perform a corresponding movement within the scope of the grooves N given to them.
  • the outer contour of the control bolt 40 during its movement in the direction of the double arrow P serves as a control curve for the functional components 21 ... 32, so that these are positively controlled in a position in which they either release or hold the coin (functional parts 21 and 22) or release or hold the key (functional parts 31 and 32), these functions being complementary to one another.
  • the arrangement of these components in the housing 10 consequently forms the coin chamber 20 through the inner sides of the two functional parts 21, 22, the arcuate end face of the control bolt 40 and the inner sides of the upper and lower covers 101, 102, which in FIG is shown with the coin inserted (but not shown).
  • the inside of the functional parts 31, 32, the W-shaped end face of the control bolt 40 and also the inside of the lower and upper cover 101, 102 form the key chamber 30, which is largely occupied by the control bolt 40 in the illustrated embodiment of FIG.
  • the two profile parts 103A, 103B have an inwardly pointing shape approximately in their center, which serves as a pivot bearing for a leaf spring 43, 44, the legs of which each act on a functional part.
  • the purpose of these springs 43, 44 is to maintain the contact of the functional parts 21 ... 32 with the outside of the control bolt 40, which serves as a control curve, so that a precise sequence of movements is ensured.
  • the functional parts 21 ... 32 have an E-shaped structure, the three fingers of this E structure A, B and C (in FIG. 1 only) designated at functional part 31) point inwards and interact with the outside of the control bolt 40.
  • control bolt 40 has an X-like structure, with a central constriction E and four end regions D, which essentially serve as a locking or stop for the fingers B of the functional parts 21 ... 32, as shown in FIG. 3 and 4 can be seen more clearly.
  • the preferred exemplary embodiment of the coin deposit lock shown in FIGS. 1 and 2 thus consists of a total of only eleven mechanically extremely simple components (four housing components, four Functional parts, a control bolt and two springs).
  • the assembly is possible by simply placing them on top of one another and screwing them, for example, which automatically holds the functional parts 21... 32 and the control bolt 40 with their guide pins Z in their associated grooves N.
  • FIGS. 3 and 4 show the two functional states of a coin deposit lock according to FIGS. 1 and 2, vertical areas being shown tinted for clarity.
  • this blockage can only be released if the key 35 is inserted into the coin chamber 30, since its front flanks 35A act on the outer sides of the fingers A of the functional parts 21 and 22 and these functional parts against the action of the springs 43, 44 push outwards.
  • the locking between the middle finger B of the functional parts 21 and 22 and the hook-like end portions D of the control bolt 40 is released, so that the end face of the key 35 in Can come into contact with the complementarily shaped end face of the control bolt 40.
  • the key 35 can then move the control bolt 40, the fingers C of the functional parts 31, 32 of the coin chamber 30 being able to slide along the outer contour of the control bolt 40 until they dip into the constriction E.
  • This immersion movement clears the way for the two opposing fingers A of the molded parts 31, 32 of the coin chamber 30 so that they can retreat and provide a sufficient removal cross-section for the coin 25.
  • the removal of the key 35 also can not thereby allowing we n, that is, for example, pressed into the coin chamber 30 with a pointed object or the like on the semi-circular end of the control latch 40 since the control latch 40 in this position, in turn, through its end portions X and the middle finger B of the functional parts 31, 32 is held, the latter practically serving as barbs here.
  • the introduction of a coin 25 into the coin chamber causes the two fingers A of the functional parts 31, 32 to be moved apart, as a result of which the blockage just described as a result of the fingers B or end sections X is first removed. After this first step when inserting a coin 25, the front side of the coin 25 can then act on the complementarily shaped front side of the control bolt 40 and initially push it backwards.
  • the concept with the guide pins also enables a kind of "information transmission" about the specific location and thus the specific locking condition of the coin deposit lock to the outside.
  • it can be achieved, for example, by extending the guide pins that they themselves act as active components during the locking process and can be acted upon, for example, by other components, such as, for example, credit cards or chetons, which are inserted into an additional coin chamber above and parallel to the coin chamber 30 can be. Coupling or operative connection with additional mechanisms is thus possible, which achieve an expansion of the field of use of the coin deposit lock according to the invention.
  • FIGS. 5 and 6 show a further exemplary embodiment of a coin deposit lock according to the invention, which is based on the same principles as the preferred embodiment described above. It will therefore suffice to consider only the essential differences of this second embodiment:
  • control bolt 41 is consequently not guided by pins and grooves, but by a web 11, 12 in the housing 10 'and is configured essentially in a dumbbell shape, the thickened ends of this dumbbell-shaped form, on the one hand, interacting with the functional parts 21'. ..32 'ensure, on the one hand, define the two end positions of the control bolt 41 by the stop function of this thickening on the web 11, 12.
  • FIG. 5 shows the key 36 inserted, it can be seen that the key is the facing end face of the Control bolt 41 acts and the latter pushes away the functional part 31 'in its part facing the housing interior and at the same time engages its outwardly pointing ' thickened end in a corresponding constriction of the key and blocks it.
  • the functional part 21 ' can rest against the thin shaft of the control bolt 41 and its front end can consequently move outward far enough to allow the coin 26 to be removed, the functional principle is thus roughly comparable to the functional principle described above for the first , preferred embodiment of the coin deposit lock according to the invention.
  • a spiral spring 46 is used to pressurize the functional parts, which bias them against one another.
  • the second exemplary embodiment of the coin lock according to the invention according to FIGS. 5 and 6 shows, however, that the principle of the inventive concept allows a wide variety of variants, which are ultimately all based on the common idea that the movement sequences of the functional components in the housing, on the one hand, and the movement sequence, and the outer contours of the control bar on the other hand, it can be defined as a control curve in such a way that reliable locking positions are achieved in complementary fashion in the coin chamber or the key chamber when the control bolt has reached one of its two end positions, which in turn are specified by defined housing shapes (for example, pins in an elongated hole guide or webs).
  • a further simplification of the designs of the coin deposit lock can consist in that instead of the spring elements 43, 44, 45, 46 magnetic forces are used for the proper guidance of the functional parts on the control bolt control cam, for example in that control bolts on the one hand and functional parts on the other hand magnetize with opposite poles are or alternatively one of these functional elements is magnetized and the other is made of ferro-magnetic material.

Abstract

L'invention concerne une serrure actionnée par des pièces de monnaie, utilisée sur des chariots de supermarchés et comprenant des éléments fonctionnels qui libèrent la clef maintenue dans un compartiment et qui assure l'accouplement au chariot suivant lorsqu'on insère une pièce de monnaie dans un compartiment réservé a cet effet, et inversement. On obtient cette fonction uniquement du fait que d'une part le contour intérieur du boîtier et d'autre part les contours extérieurs des éléments fonctionnels correspondent de manière à ce qu'un élément fonctionnel puisse toujours passer librement dans son compartiment, d'une position de fermeture à une position de déverrouillage. Il existe notamment un verrou de commande inséré dans le boîtier, qui lorsqu'on le fait glisser entre deux positions extrêmes, commande les éléments fonctionnels du compartiment destiné à recevoir la pièce et du compartiment réservé à la clef, de manière à ce que sa face extérieure serve de came de commande auxdits éléments fonctionnels. Cette serrure actionnée par des pièces de monnaie peut être réalisée particulièrement aisément de manière qu'elle soit robuste et fiable, cela à l'aide d'éléments simples. Sa fabrication et son utilisation sont par ailleurs économiques.
