Definitions

  • the present invention relates to a device for locking shopping carts, transport trolleys or the like with the features of the preamble of patent claim 1.
  • each carriage has a locking element and a locking device and an actuating device assigned to the locking device.
  • the locking element of each carriage is in engagement with the locking device of a second carriage arranged in front or next to it, this engagement being releasable by inserting a coin, a chip or the like into the actuating device, so that only one carriage is removed at a time and can be used accordingly.
  • an embodiment is used in which the actuating device again issues a coin or the like when the locking element is inserted into the locking device. This is intended to motivate the respective user of the trolley to return the trolley used to a predetermined position after use, so that the trolleys used do not stand around untidily, which can be observed particularly frequently in shopping trolleys at supermarkets.
  • the known device described above has the disadvantage that a locking device and an associated actuating device are required on each carriage in addition to the locking element. This requires a high investment, so that such cars are relatively expensive because of the additional locking device and the actuator. In addition, the actuating device and / or locking device provided on each carriage can be easily damaged, so that the known device requires a relatively high repair effort. This is particularly true if the actuating device comprises a coin validation device, since such a coin validation device is particularly sensitive and can therefore easily fail when subjected to a somewhat heavy load or improper handling of the car and is therefore a further source of interference.
  • the present invention has for its object to provide a device of the type specified, which is relatively inexpensive to manufacture with a particularly low susceptibility to failure.
  • a device for locking trolleys in particular shopping trolleys, transport trolleys, luggage transport trolleys or the like is proposed, in which the locking device is designed as a locking rail.
  • the locking element can be guided into and out of the locking rail in this locking rail and is held there in an axially sliding manner.
  • the locking rail is provided with the actuating device which, when a coin or the like is inserted, releases the locking rail for the removal of a locking element which is attached to a carriage, so that the carriage can be used according to its purpose.
  • the other end of the locking rail is blocked for the locking element to be brought out.
  • the other end of the locking rail is provided with a further actuating device, so that when a coin or the like is inserted into this actuating device, the locking rail is released for the removal of a locking element and thus a carriage can be removed from the device.
  • the device according to the invention has a number of advantages. Due to the design of the locking device as a locking rail, it is possible for a plurality of carriages to be particularly easily locked to the device according to the invention, each carriage having only the locking element and a single central locking device locking the plurality of locking elements. This in turn leads to the device according to the invention being compared to the known device described at the outset can be manufactured particularly inexpensively, since only a single stationary locking device and therefore only a single actuating device are required.
  • the device according to the invention can be used in many ways. For example, it is possible to design the actuating device assigned to the locking device in such a way that the coin or the like thrown into the actuating device is not released again, and thus a rental fee for a car is automatically collected. There is also the possibility of designing the device according to the invention in such a way that a coin or the like thrown into the actuating device is issued again when a locking element is inserted into the locking rail, ie thus a carriage is returned after use and is locked on the device.
  • Such an embodiment has the additional advantage that the respective user, in order to get back his inserted coin, which is for example a one-mark piece, two-mark piece or five-mark piece, is forced to lock the carriage again at the device according to the invention.
  • This ensures that the trolleys are always returned to the same place from which they were previously removed, such an embodiment of the device according to the invention also being able to be used in particular for shopping carts in supermarkets, especially since the device according to the invention is technically very useful simple means, particularly inexpensive and can be implemented without great effort.
  • the locking rail used in the device according to the invention can in principle be of any shape, it only having to ensure that the locking rail slides the plurality of individual locking elements in such a way that the locking elements can only be removed over one head side or over both head sides of the locking rail. So it is possible, for example, that the locking rail has a rail run designed as an elevation, the z. B. is ⁇ -shaped. Then, from a head side or from both head sides of the rail, the locking elements correspondingly adapted to the rail run can be pushed one after the other or pulled off individually from the rail run via a head end or both head ends, so as to remove the trolleys, in particular shopping trolleys, to lock or release individually.
  • the locking rail is designed as a hollow profile and has an axially extending slot-shaped recess.
  • the opposite end of the locking rail is blocked in the simplest case by the slot-shaped recess not extending to this end, but rather at a certain distance, for example approximately 5 cm to about 10 cm, before this end of the locking rail ends.
  • the design of the locking element cooperating with such a locking rail depends on the cross section of the Hohlpro fils the locking rail.
