Definitions

  • the invention relates to a device for borrowing transport trolleys, consisting of a number of stackable transport trolleys, in particular shopping trolleys, and at least one fixed collection point, each transport trolley being equipped with a coupling part which has a plug-in part and a locking shaft, so that the transport trolleys by means of their coupling parts can be coupled to one another in a stack row, that each coupling part also has a device for receiving and returning a coin deposit, and after the coin has been received, the device releases a lock contained in the coupling part, such that the plug-in part of an adjacent trolley or one on the Collecting station located stand from the locking shaft of the coupled transport carriage can be removed so that this transport carriage can be removed from the stack and that for the purpose of recoupling the locking one again
  • the trolley returned to the collection point is done by inserting the plug-in part of a preceding trolley or that of the support stand into the locking shaft of the coupling part of the returned trolley and then releasing at least part of the previously paid coin deposit and finally at the collection point in the
  • collection points are provided, to which the customer returns the transport trolley, which he has borrowed and is equipped with a coupling part, and thus contributes to the fact that unused transport trolleys do not stand randomly and scattered around in parking lots.
  • the collection points are designed so that rows of stacking trolleys are aimed for in a predetermined length. These predetermined lengths are, however, often increased by the carelessness or by the unreasonableness of trolley users in that returned trolleys are coupled to one and the same stack row until the stack row extends into the lanes of the parking spaces belonging to the self-service market and thus completely significantly affect the flow of traffic in these parking lots.
  • Document EP-A-0 513 661 represents a state of the art according to Article 54 (3).
  • a shopping trolley is moved in the effective range of a magnetic field, locking elements are switched back and forth between a locking position and a release position.
  • each coupling part is arranged so that when the force field of the magnet acts in a position that partially takes up or closes the space of the locking shaft and when the influence of the magnetic force field diminishes with the aid of a force on the locking member acting reset member is movable into a position releasing the space of the locking shaft for the plug-in part.
  • the invention advantageously uses an extremely simple and therefore inexpensive solution, the effect of which is that it is the most predetermined in the force field Arranged at the end of a stack of magnets is no longer possible to couple a trolley returned to the collection point to the last transport trolley located in the collection point, since the free plug-in part of this transport trolley can no longer be inserted into the locking shaft of the coupling part of the returned transport trolley.
  • the locking member which partially takes up the space of this locking shaft, has the effect that the plug-in part of the preceding transport carriage can no longer be inserted into the locking shaft of the coupling part of the returned transport carriage such that a coupling actually takes place.
  • the returned trolley can therefore no longer be coupled to the stack row.
  • the coin deposit remains in the coupling part.
  • the user of the trolley has to look for another still free stack row to which he can couple his trolley. An automatic length limitation of the stack row is achieved.
  • the length of the magnet or a magnetic strip is furthermore advantageous to choose the length of the magnet or a magnetic strip to be greater than the length of the stacking distance of two coupled transport trolleys pushed into one another. This ensures that the trolley that would extend the stack row beyond the desired dimension is gripped by the force field of the magnet and brought into a state preventing the coupling.
  • the locking member is expediently a simple part that does not have to be worked extremely precisely. Its task is simply to somehow block the locking shaft of a coupling part for a plug-in part to be inserted. This can be done in a relatively imprecise, but no less safe way, especially since the plug-in part of previously known coupling parts is also designed as a simple stamped sheet metal part. The manufacturing costs of such a blocking system can therefore be kept relatively low will.
  • the coupling part of each trolley is guided past the magnet.
  • the force field of the magnet causes the locking member to be tightened and protrude into the locking shaft. If the stack row has not yet reached its predetermined length, the trolley must be pushed past the magnet in order to be able to couple it to the last trolley of the stack row.
  • the returned trolley with its coupling part comes out of the effective range of the magnet again, so that the locking member protruding into the locking shaft is pulled out of the locking shaft at least so far by the action of the restoring element that the plug-in part of a transport trolley in front can be inserted so far that it is possible to couple the two transport carriages.
  • Fig. 1 shows a device 1 consisting of a number of trolleys 2, 2 ', in the example they are telescopic shopping carts, and from at least one collection point 4.
  • Each trolley 2, 2' has a coupling part 9, for example one according to EP 90906159.0, so that these trolleys 2, 2 'in can be coupled to a stack row 22 in a known manner.
  • a holding stand 5 is expediently located at the collecting point 4, to which a first transport carriage 2 can be coupled.
  • Transport trolleys 2, 2 'of this type, their coupling parts 9 and the collection point 4 with a support stand 5 belong to the long-known prior art, so that a detailed description is unnecessary at this point.
  • a magnet 7, which can also be a magnetic strip, is located furthest from the support stand 5, preferably stationary and, for example, resting on a post 6, at the level of the coupling parts 9 of the transport carriages 2, 2 '.
  • the magnet 7 or the magnetic strip can consist of at least one permanent magnet; however, the magnetic force field can also be generated in a known manner using electrical energy.
  • the drawing shows how a transport carriage 2 'is moved to the collection point.
  • the effective area 8 of the magnetic lines of the magnet 7 is shown by curved lines.
  • the trolleys 2, 2 ' can be released in a known manner only by paying a coin deposit from the stack row 22 or from the support stand 5, the coin deposit being inserted into the coupling part 9 of the transport trolley 2' to be removed, so that a lock located in the coupling part 9 solved and thus the pulling out of the preferably flexibly fastened plug-in part 14 of the preceding transport carriage 2 is possible.
  • This process has also been known for a long time and therefore need not be described in more detail.
  • the proposed device 1 also assumes that when a trolley 2 'is returned to the collection point 4 and after coupling to a preceding trolley 2, at least part of the coin deposit previously paid will be reimbursed.
  • the coupling part 9 has a coin holder in a known manner - And a coin input and output device 10. Since these devices 10 are not part of the invention but rather of the prior art, a detailed description is also omitted here. It should only be mentioned that the coupling parts 9 are equipped either with a coin slide button or with a coin insertion and ejection opening.
  • each transport carriage 2, 2 ' is also equipped, according to a known manner, with a locking shaft 11 into which the plug part 14 of the coupling part 9 of a further transport carriage 2 can be inserted and locked with the coupling part 9 of the first-mentioned transport carriage 2'.
  • the plug-in part 14 of the further transport carriage 2 is shown in the position in which it is either inserted into the locking shaft 11 or moved out of it.
  • a locking member 16 is arranged in a guide 15 in the interior of the coupling part 9 so that it can be moved.
  • the locking member 16 is passed below or above the locking shaft 11 below or above it and has a hook-like projection 17 on the left in the drawing, which, for example, leads upwards and is directed to the locking shaft 11.
  • the blocking member 16 which is made of ferromagnetic material, is equipped with a plate-shaped section 18 which, with its free surface 19, faces the magnet 7.
  • a reset member 21 engages with one end in the locking member 16. With the other end, the reset element 21, which is designed as a tension spring in the example, is attached to the housing 13 of the coupling part 9.
  • the reset member 21 holds this Locking member 16 in a position in which the projection 17 of the locking member 16 either does not protrude into the locking shaft 11 at all, or the projection 17 is positioned such that it can no longer hinder a plug-in part 14 to be inserted, for example in that a plug-in part 14 can push the projection 17 to the side.
  • the coupling part 9 approaches the magnet 7, its force field pulls the locking member 16 toward it, so that the projection 17 of the locking member 16 projects into the locking shaft 11, i.e. occupies a position that partially occupies the space 12 of the locking shaft 11 or occupies it ( 12) closed, see dash-dotted illustration.
  • the locking member 16 If the locking member 16 is in this position, it blocks a plug-in part 14 to be inserted in such a way that it cannot be locked with the coupling part 9. However, if the coupling part 9 is moved again out of the force field of the magnet 7, the reset member 21 gradually pulls the locking member 16 towards itself again, so that the projection 17 leaves the locking shaft 11 more and more.
  • the person skilled in the art will choose the projection 17 of the locking member 16 and the shape of the plug-in part 14 in such a way that there can be no jamming if someone tries to insert the plug-in part 14 into a locking shaft 11 blocked by the projection 17 and lock it there. Also, you will create certain support surfaces, not shown, for the projection 17 of the locking member 16 in the locking shaft 11, in order to avoid damage to the locking member 16, should anyone try to push the plug 14 with great force into the locked locking shaft 11.
  • the locking member 16 is arranged in a guide 15 located transversely to the longitudinal extent of the locking shaft 11, the example according to FIG. 3 shows that the locking member 16 can also be rotatably arranged on a vertically arranged axis 20.
  • the drawing shows that the locking member 16th again has a hook-like projection 17 which can be moved into the locking shaft 11, so that it takes up part of the space 12 of the locking shaft 11 there. From the projection 17, the locking member 16 leads below or above the locking shaft 11 in the direction of the magnet 7, where it again has a relatively large-area plate-shaped section 18 at its end, which is directed with its free surface 19 towards the magnet 7.
  • the reset member 21 is in turn attached, which is arranged with its other end on the housing 13 of the coupling part 9 stationary.
  • the reset member 21 holds the locking member 16 in a position in which it cannot hinder a plug-in part 14 to be inserted.
  • the coupling part 9 approaches the magnet 7, its force field pulls the locking member 16 toward it, so that the projection 17 of the locking member 16 projects into the locking shaft 11, i.e. occupies a position that partially occupies the space 12 of the locking shaft 11 or occupies it ( 12) closed, see dash-dotted illustration. If the locking member 16 is in this position, it blocks a plug-in part 14 to be inserted in such a way that it cannot be locked with the coupling part 9. If, however, the coupling part 9 is moved again out of the force field of the magnet 7, the reset member 21 gradually pulls the locking member 16 back towards itself, so that the projection 17 leaves the locking shaft 11 more and more.
  • the length of the magnet 7 or that of the magnetic strip measured in the longitudinal extent of the stack row 22 will be chosen longer than the stacking distance of two nested transport carriages 2, 2 '. Then it can not happen that two coupled transport trolleys 2, 2 'are placed in relation to the magnet 7 so that the coupling part 9 of one transport trolley 2 in front and the coupling part 9 of the other transport trolley 2' behind Magnet 7 and thus are outside the effective area 8 of the magnet 7. If the latter were the case, an automatic length limitation of the stack row 22 could not be achieved.
