Definitions

  • a springbiased locking ratchet is coordinated to the locking latch. and a coin is adapted to be displaced jointly with the locking latch and to lift the locking ratchet with its edge during the advancement.
  • a locking plate is disposed above the locking ratchet sitting rigidly on the locking latch and cooperates in a tumberlike arrangement with the locking ratchet.
  • the present invention relates to a lock with a locking function to be operable by insertion of a coin.
  • the locking plate cooperates with its toothed underside pointing towards the locking ratchet with an angularly shaped end of the locking ratchet.
  • a favorable structure design is realized, in accordance with the present invention, such, that the locking plate extends parallel above the inner side guide wall of the coin insert slot.
  • a further advantageous design is obtained, in accordance with the present invention, such, that the pin or the like holding the coin in the coordination to the latch is releasable from its holding position.
  • an advantageous feature of the present invention resides in the fact, that the operating key is mounted in the latch and runs in a slot guide of the lock housing bottom such that it forms the latch guide.
  • an advantageous solution of the present invention is found in the fact, that the operating key in case of a displaced latch is locked against pushing in, preferably by an arrangement according to which the operating key steps out with its inner end from the opposite position to an escape opening in front of the lock cover.
  • a coin-operated lock is created, which is of simple structure with an extremely high security of use.
  • the lock can be framed particularly favorably as a security lock, that means the coin remains after the closing in the lock as security for the key and falls out again when the lock is opened.
  • the lock can, however, be constructed likewise as a collecting lock, that means the coin falls into a closed container.
  • a nondesirable closing of the lock, at which occasion the locking ratchet is brought out of its resting position with the locking latch, by means of a wire inserted through the coin insert slot, is prevented.
  • the locking ratchet enters in case of such sensing advantageously into a locking position with the locking plate rigidly mounted on the locking latch.
  • the corresponding locking plate cannot be operated by means of an object inserted into the coin insert slot, as for instance a screwdriver or the like, since it is disposed above the inner side guide wall of the coin insert slot.
  • the slot can be advantageously equipped without great endeavor with a coin returning device. Erroneously falsely inserted coins or damaged coins can be returned, since a holding pin is releasable from its holding position.
  • This pin is preferably provided on a spring biased plate displaceable substantially crosswise to the moving direction of the latch.
  • the plate carries the operating key, which is freely disposed towards the lock front side. By a slight pressure on the key the pin holding the coin is controlled out of its holding position over the plate.
  • the key mounted in the locking latch serves also for the guide of the locking latch.
  • the structural arrangement serves the further increase of the safety of use, since a nonintentional operation of the return device, for instance by cumbersome packages, is to a great extent prevented.
  • the return function is exclusively possible in connection with a completely closed latch, since the operating key enters only in this position in opposite arrangement to the escaping opening of the lock cover arranged in accordance with the present invention. In each other position of the latch the return device is blocked by the lock cover, against which the inner end of the operating key abuts.
  • FIG. 1 is a back elevation of the coin-operated lock with the locking latch being withdrawn;
  • FIG. 2 is a front elevation of the coin-operated lock
  • FIG. 3 is an elevation similar to that of FIG. 1, however, with the lock cover being removed;
  • FIG. 4 is a view similar to FIG. 3, however, showing the started closing process
  • FIG. 5 is again a front elevation showing the coin-operated lock upon completed closing process in the position in which the key is removable;
  • FIG. 6 is also an elevation similar to that shown in FIG. 3, wherein the coin-operated lock has a partly withdrawn locking latch and a freed coin;
  • FIG. 7 is a section along the lines 7-7 of FIG. 3;
  • FIG. 8 is a section similar to that of FIG. 7, however, with a pushed-in operating key
  • FIGS. 9-11 are fragmentary elevations in an enlarged and simplified showing of the locking plate in different positions of the locking latch.
  • the coin-operated lock comprises a lockbox l.
  • the lockbox I has sidewalls 3, 4, 5 and 6, which extend at an angle from the lock bottom 2.
  • the lock guard is covered up by the lock cover 7, which is secured by means of securing screws 8.
  • the latter enter in distancing bushings 9 and 9', respectively.
  • a cylinder lock 10 is secured to the cover 7. Its cylinder core 12, operable by means of a key 11 extends into the inside of the lock. It carries at its end a closing wing 13, the driver pin 14 of which extends into a driver slot 15 or the closing latch 16.
  • a locking ratchet 17 is swingably mounted above the locking latch 16 about the distancing bushing 9'.
  • a holding spring 18 bent like a hairpin and disposed about the distancing bushing 9' engages the locking ratchet 17 in the direction of the corresponding narrow longitudinal side 19 of the locking latch 16.
  • the narrow longitudinal side 19 is there equipped with a recess 20 into which the angularly bent end 17' of the locking ratchet l7 enters.
  • the locking ratchet 17 is coordinated above the latter to a locking plate 21 sitting rigidly on the locking latch 16.
  • the latter has a toothed bottom side including the recesses 22, 23 and 24.
  • the locking plate 21 is disposed in the lockbox 1 on the locking latch 16 such, that it extends parallel above the inside guide wall of the coin insert slot 26.
  • the coin insert slot 26 started in the lockbox wall 3.
  • the lock is disposed in open position.
  • the key 11 is not removable in this position.
  • the angularly bent end 17 of the locking ratchet 17 disposed in the recess 20 prevents a closing of the locking latch 16.
  • the locking ratchet 17 is brought out of engagement with the recess 20 over the coin edge (see FIG. 4).
  • the coin 28 is now advanced by the pin 29 over the supporting shoulder 27, until it slides away from the supporting shoulder 27, whereby the resilient locking ratchet 17 accelerates shocklike the coin fall.
  • the operating key 31 is pushed whereby the pin 29 is moved over the plate from its position holding the coin 28, so that the coin passes through and emerges from the slot 38 (see FIG. 8).
  • the operating key 31 is locked against the lock cover 7.
  • the coin return device can be successfully operated at any time. In this position the operating key 31 is disposed within the range of an escape opening 41 of the lock cover 7 (see FIG. 1), so that the plate 30 can be displaced a further required length causing the freeing of the coin.
  • a supporting shoulder 27 on the lock bottom 2 which supporting shoulder limitsjointly with a pin 29 the insert movement ofthe coin 28.
  • the pin 29 sits on a plate 30 displaceable crosswise to the direction of movement of the locking latch 16 and passes through an opening 16' of the locking latch 16.
  • the corresponding plate 30 is abutted by the blade spring 13 in the direction towards the wide side of the locking latch 16.
  • the pushbuttonlike operating key 31 is secured to the plate 30, which operating key 31 is mounted in a bushing 32 of the locking latch 16.
  • the bushing 32 runs in a guide slot 33 ofthe lock bottom 2, whereby the locking latch guide is formed.
  • the guide slot 33 is framed in accordance with the slot contour.
  • the corresponding frame 39 has such thickness, that the head 31' of the operating key 31 is sunk in and is thereby disposed protected in the frame opening 40.
  • the locking latch 16 stands under the effect of a latch spring 34 disposed on the bushing 9, which latch spring 34 retains the locking latch 16 in its prevailing abutment position.
  • a bentover stay 35 which guides the coin 28 by means of a plate 36 sitting on the locking latch 16.
  • the coin-storing chamber formed by the stay 35 and the plate 36 can be brought into a flush position with a coin outlet slot 37 of the lockbox wall 4 depending upon the position ofthe locking latch 16.
  • the locking plate 21 equipped at its underside with toothed recesses 22, 23 and 24 does not disturb the closing function of the lock in case ofa correctly inserted coin.
  • a false coin and a coin having a larger diameter would move during the closing process the locking ratchet 17 into the position indicated in point-dotted lines in FIG. 9.
  • the angularly shaped end 17 enters into the toothed recess 22 of the locking plate 21.
  • the closing movement is not performable, due to this locking.
  • these toothed recesses prevent a closing of the locking latch 16 if in a nonpermissible manner the locking ratchet 17 is brought from the engaging effect with the opening 20 of the locking latch 16 by means of a wire put through the coin insert slot 26 and if the angular end 17' enters the toothed opening 22, 23 or 24 (see FIGS. 9 to 11).
