Definitions

  • the invention relates to a transport trolley, in particular a shopping trolley, with a coin lock and a key for connecting one of the cars standing in a parking column or for releasing the car, preferably at the end of the column, by entering a coin into its coin lock, whereby the coin lock locks the coin when the car is released and releases the coin when the car is reconnected.
  • Transport trolleys with this deposit system are known in principle from DE-A 25 54 916 and are now on the market in various embodiments.
  • each transport trolley is provided with a coin lock and a key, usually hanging on a chain.
  • the key of the penultimate carriage or the key hanging at a collection point is in the coin lock of the carriage, whereas the own key is available for coupling the next carriage following.
  • the wagon standing at the end of the column should be uncoupled.
  • the present invention is based on the task of reducing the effort for the coin lock, in particular its dimensions.
  • the coin lock should be easier to integrate into the carriage, that is, it should protrude less into the loading space or beyond the outer contour.
  • the coin lock should be characterized by ease of use and low production costs.
  • the deposit coin in the coin lock carries out a shift approximately in the direction of its axis of rotation when the carriage is released.
  • the invention is based on the following finding: for which purpose a slide protruding from the coin lock is usually used, into which the coin is first inserted and which is then used to release the key of the front carriage must cover a fairly large sliding path. Even with the greatest design effort, the sliding path and thus also the length of the slide projecting from the coin lock can never be less than the coin diameter.
  • the deposit coin in the system according to the invention executes its active path in the direction of the coin axis and consequently its displacement path and the resulting dimensions of the coin slot are significantly smaller than in the known systems.
  • a displacement path that is in the order of the coin thickness.
  • a displacement of 1 mm to approx. 1 cm is recommended.
  • the coin lock has a coin holder, which is preferably rigidly installed in the coin lock and has the shape of a bowl that takes up the coin with a slight clearance, and that at least one spring with a movable slide parallel to the coin axis moves under the Protection of cantilevers with its cross-section protrudes into the cross-section of the coin holder in such a way that it protrudes from the Deposit coin, but cannot be depressed by a next smaller one, whereby in the non-depressed position it interlockingly engages in recesses of the key inserted into a cavity of the coin lock, but in the depressed position releases it and at the same time in turn releases it from the locked key against spring pressure tensioned means is locked against springback and thus blocks the coin in the coin holder.
  • the slide is expediently designed as a cylindrical bolt with two annular grooves, the upper one of which is used to hold the coin in the coin holder in a form-fitting manner, the lower one is used both for releasing the key and for its own locking by means provided for this purpose. You get by with very few, easy to manufacture parts.
  • the means for locking the slide in its pressed-in position can be formed by a bolt which is guided into the cavity mentioned for the key and which engages in recesses in the slide when the key is pulled out by spring force, but releases the slide when the key is inserted so that he shifts the coin into its upper release position.
  • the slide must have correspondingly offset active surfaces for engagement with the coins in the case of coins of different sizes, it may be expedient for manufacturing reasons to form the slide by three successive sections in the longitudinal direction, of which the middle one with the key, the two outer ones each correspond to a deposit coin, the sections being resiliently braced with one another in both axial directions.
  • 0 shows a column of shopping trolleys coupled to one another
  • Fig. 1 is a plan view of a first design of the coin lock from above with a partial section along the line E in Fig g. 8th; 6 shows a section along the line B in FIG. 6; FIG. 7 shows a section along the line D in FIG. 7; FIG. 7 shows a section along the line F in FIG. 1 shows a view similar to FIG. 7, but with an inadmissible unlocking attempt;
  • FIG. 11 shows the same view as FIG. 10, but with the coin locked
  • Fig. 12 shows a vertical section through Fig. 10 along the line G and
  • FIG. 13 is a side view of FIG. 11 in the direction of arrow H.
  • FIGS. 6, 7 and 9 are sections in the parting plane of the coin lock housing, that FIGS. 1, 2, 4 and 6 and the left half of FIG. 8 on the one hand, FIG. 3, 5, 7 and the right half of FIG. 8 on the other hand each represent the same operating states.
  • FIG. 1 The coupling principle is first illustrated in FIG. One can see there numerous shopping trolleys A which have been driven against one another and each have a coin lock B and are thus connected via a flexible element 5 to the respective neighboring trolley or to a stationary collection point C. If a wagon - generally the wagon standing at the end of the column - is to be uncoupled, a pawn coin must be inserted into its coin lock, whereupon the coin lock releases the connection to the wagon in front of it. Conversely, the user gets his coin back when the car is recoupled. T-
  • a lower housing part 1 of the coin lock B is connected with rivets 2 to an upper housing part 3 and is in turn fastened on the handle tube 6 of a shopping cart by means of a screw 4 with the interposition of a flat belt 5.
  • a key 8 is fastened by means of rivets 7. This is not shown in the drawings, however the key 8 of the same type, which is attached to the end of the flat belt 5 ', which belongs to the next carriage in the parked column in the direction of travel.
  • the housing parts 1 and 3 form between them a cavity 14 of such a height that the key 8, which is made of sheet metal of approximately coin thickness, can be easily inserted.
  • the cavity 14 contains two bars 15 and 15 'with lugs 16 and a bridge 17 which is under the action of a compression spring 18.
  • the system is initially in the state shown in FIGS. 1, 2, 4, 6 and 8, left half, in which the carriage, on the handle tube 6 of which the device shown is mounted, is connected to the next carriage via the flat band 5 ' is. 6 that the key 8 cannot be removed, since the bolts 10 and 10 "partially engage in recesses 19 which it has on the side. At the same time, it holds the bridge 17 against with its front edge 20 the action of the spring 18 back and over i re lugs 16 and the latches 15 and 15 'out of engagement.
  • the cup-like coin holder 22 is sunk in the region of the overhangs 27. This is dimensioned so that the coin fits into it with little play, and its central axis is approximately in the same plane as the axes of the bolts 10 and 10 '.
  • the bores 9, 9 ' are also arranged in such a way that their cross-section projects into the coin holder 22 by a little less than the difference in radii of the deposit coin to the next smaller coin. At the edge of a stop 23 is also available.
  • the key 8 presses with its front edge 20 both the bridge 17 and the tabs 15, 15 'via the lugs 16 the starting position back, the recesses 19 covering the cross section of the bores 9 so that the bolts 10, 10 'snap into the upper position under the action of the springs 11. At the same time, they lock the key 8 against being pulled out and raise the coin 24 to the level of the surface 21, so that it can be easily pushed out to the left.
  • the system should be stimulated with some improvised tool to release the coin so that the car does not have to be pushed back. If one pushes the bridge 17 back by placing one approximately in the middle, the bars 15, 15 'do not follow and the coin remains blocked. If, on the other hand, the bridge 17 is hit strongly from the side or the tool is even positioned approximately in the direction of the arrow 25 on the nose 16 of the bolt 15, the parts 15, 17, 15 'become jammed against the walls of the recess 14 long before Latch 15 is pushed out of engagement.
  • the fastening screw 4 is already installed when the device is installed. It can then be tightened through an opening 26 in the upper housing part 3, for which purpose the bridge 17 can be pushed back with a suitable tool. Later, the path to the screw is always blocked either by the coin 24 or the key 8, so that the device cannot be unscrewed by unauthorized third parties. If necessary, the screw is then best made accessible by using a key 8 with a corresponding hole.
  • FIGS. 10 to 13 A second embodiment of the invention is shown in FIGS. 10 to 13. It allows the use of two different deposit coins.
  • a coin holder 22a or 22b is installed in the coin lock there on the left and right of the cavity 14 for inserting the key 8, and each coin holder has displaceable edges perpendicular to the coin plane Slider 10a or 10b so that the coin lock can be operated from each coin holder.
  • the slides 10a and 10b function according to the same principle as in the previously described embodiment, they are only matched to the different diameters of the deposit coins provided and are therefore offset relative to one another.
  • the slides 10a and 10b are not formed in one piece as in the previous exemplary embodiment, but are separated from one another by a separate intermediate piece 10c and 10c 1 .
  • This intermediate piece 10c or 10c ' is resiliently clamped between the two sliders 10a and 10b or 10a' and 10b 'and engages in the recesses 19 of the key 8 when no coin is inserted, cf. Fig. 12.
  • intermediate pieces 10c and 10c ' correspond to the bolts 15 and 15' already described, which in turn are operatively connected to the bridge 17 via the lugs 16.
  • the two embodiments described have the advantage in common that the active actuation path of the coins takes place in the direction of the coin axis and consequently very small actuation paths and a particularly compact design of the coin lock are achieved.
