Description

  The present invention relates to a key system that enables loading / unloading of a bag with a predetermined number of coins, such as a coin locker.

  Conventionally, the key system of a coin locker opens a door, puts a load in the coin locker, inserts a predetermined number of coins from the coin insertion slot, closes the door, and inserts a custom key that has been previously inserted into the key cylinder in the locking direction. The user was supposed to have this custom key after turning and pulling out.

  However, the conventional key system can only take out and put in the baggage once with a predetermined number of coins. When you want to open and close the coin locker for loading and unloading the baggage several times, I had to throw it in.

  Conventionally, in order to eliminate such disadvantages, even if the custom key in the key system of the coin locker is locked once and then the custom key itself is pulled out from the custom key insertion cylinder, the reset push pin is not finally pushed, A key system can be used to open and close the door as many times as possible using a custom key, so that the user can load and unload the coins from the coin locker without inserting a new coin into the coin slot. Has been. In other words, a recovery coin passage that continues to the coin insertion slot and a return coin passage that communicates with the coin return slot are arranged side by side, and coins are inserted into both passages so that a custom key can be used unless the reset push pin is pressed. The door can be opened and closed any number of times, and when the coin locker is finally stopped, the coins in the recovered coin passage are dropped and recovered by pressing the reset push pin in the unlocked state, and the return coin The coins in the aisle are dropped into the coin return slot.

Furthermore, there is a coin locker locking device as disclosed in Patent Document 1 as a specific example of such a conventional coin locker key system. In other words, a coin passage that continues to the coin insertion slot and a return coin passage that communicates with the coin return slot are arranged side by side, and a coin holding plate is rotatably provided in each passage. In the locked state, the movement restraining member provided on the locking rod drive lever restrains the operation of the coin holding plate, and the operation of the coin release operating shaft is absorbed by the contraction of the drive coil spring, and the coin is released. In the locked state, the operation of the coin release operating shaft is transmitted to the coin holding plate via the drive coil spring to release the coin held by the coin stopper.

  However, the conventional key system allows the user to use the coin locker for loading and unloading many times without inserting new coins, but the user accidentally inserts the reset push pin during the operation before the final use. In many cases, the coins are pushed and the collected coin passage is opened in the middle of use, and the coins on hold are dropped and collected. For this reason, there is an inconvenience that it cannot be reused unless a new coin is inserted and then re-operated.

  Therefore, the present invention was created in view of the existing circumstances as described above, and even after the custom key in the key system of the coin locker is once locked and the custom key itself is extracted from the custom key insertion cylinder, Ultimately, you can use the custom key to open and close the door as many times as you want without pressing the reset push pin, and even if the user accidentally presses the reset push pin during use After the coin is inserted into the coin insertion slot, the coin locker can be loaded and unloaded any number of times without re-operation, and when the custom key is removed from the custom key insertion cylinder after locking, the return coin path By collecting all the coins in the collected coin passage in advance, An object of the present invention is to provide a key system that was to be able to easily perform the locking and unlocking of the door many times by using a custom key only by a coin which had been staying in retirement coin passage.

  In order to solve the above-described problems, in the present invention, a front frame having a custom key insertion cylinder, a coin insertion slot, and a coin return slot, and a pay coin path and a deposit coin path leading from the coin insertion slot are formed. A key system having a side frame formed on the side surface of the front frame to detect when a predetermined number of coins are introduced into the paid coin passage, and the inserted coins are further detected on the deposit coin passage side. A path switching lever that guides the coin, a surplus coin insertion prevention lever that prevents excessive coins from being introduced into the deposit coin path, and an engagement / disengagement pin that retracts when the custom key is pulled out from the locked custom key insertion cylinder. The coin number that can be dropped in the collection box by opening the And over bets are those with a reset push pin dropping the coins are staying deposit coin passage to open the locker after use return stop Furaketto.

  A return coin temporary fixing lever is rotatably attached to the rotating shaft side of the number switching plate, and a protrusion protruding at one end on the lower side of the return coin temporary fixing lever is opposite to the locking piece of the return stop bracket. When the coin is stopped on the pay coin passage side, the passage change lever is mounted on the protrusion on the pay coin passage side of the passage switching lever. Is pushed up by the coin together with the protrusion of the return coin temporary stop lever, the return protrusion bracket is locked by the other protrusion of the return coin temporary stop lever, and the movement of the return stop bracket in the opening direction is prevented, Holds the coin in the deposit coin passage so that it does not fall into the coin return slot even if the reset push pin is pushed before locking after inserting the coin. It is obtained by the.

  A return stopper is engaged with the protrusion protruding to the other side of the peripheral side surface of the latch lever bracket, and the return stopper is engaged with the return stop bracket via the protrusion of the return stop bracket at the locking rotation position of the latch lever bracket by the custom key. By preventing the rotation in the opening direction and maintaining the closed state at all times, even if the reset push pin is pressed, the coin is stopped and retained in the deposit coin passage by the coin stop screw of the return stop bracket. Can be.

  Also, at the tip of the latch lever bracket, there is a coin checker that is urged to rotate in one rotation direction, and a checker stopper that is coaxial with the coin checker and pivoted in both right and left rotation directions. The coin checker tip side is retracted from the deposit coin passage when the coin is stopped in the deposit coin passage, allowing the latch lever bracket to rotate in the locking direction by the custom key, and the coin in the deposit coin passage When the is not stopped, the coin checker is locked to prevent the latch lever bracket from rotating by the custom key, and the custom key is pulled out from the latch lever bracket to prevent the coin checker from rotating by the checker stopper. Can be configured as

  Further, on the rear side of the coin insertion slot, there is a selector arm that can be rotated with one end as a fulcrum, and a V-shaped link plate that can be rotated while the tip end side of the selector arm is engaged. Only the coin of the appropriate size inserted from the coin insertion slot pushes up the selector arm with the fulcrum as the rotation center, and the tip of the selector arm rotates the one end side of the V-shaped arm of the link plate upward. The other end side of the V-shaped arm is pushed up and retracted integrally so that the coin can be guided.

  In the key system according to the present invention configured as described above, coins having a predetermined number inserted into the coin insertion slot on the upper side of the system main body are temporarily stopped in the pay coin path and the deposit coin path inside the system main body, In the meantime, even if the custom key is locked after the door is closed, the custom key is unlocked again so that the door can be opened unless the reset push pin is pressed.

  Then, when the custom key is pulled out with the door closed, the coins stopped in the pay coin path inside the system main body are dropped into the collection box on the lower side. At this time, the coin in the deposit coin passage inside the system main body is stopped as it is.

  Also, even if the reset push pin is pressed while the custom key is locked, the return stopper prevents the return stop bracket from rotating in the opening direction via the protrusion of the return stop bracket. The coin is stopped and maintained in the deposit coin passage by the coin stop screw. Thereby, even if the user does not intend to stop using the lock after locking, even if the user pushes the reset push pin by mistake, the coin is not returned, and the lock / unlock operation can be performed again with the custom key.

  Thus, if you want to stop using the coin locker in the end, press the reset push pin while the custom key is unlocked, and the coins stopped in the deposit coin passage inside the system body will be It is dropped to the return port and returned to the user, making it impossible to lock with a custom key.

  According to the present invention, even if the custom key in the key system of the coin locker is locked once and then the custom key itself is extracted from the custom key insertion cylinder, the custom key is used as long as the reset push pin is not finally pushed. The door can be opened and closed any number of times, and even if the user accidentally presses the reset push pin during use, the coin locker can be loaded and unloaded without newly inserting a coin into the coin slot. It can be done any number of times, and when the custom key is pulled out from the custom key insertion cylinder after locking, all the coins in the collected coin passage are collected in advance while the coins in the return coin passage are stopped. After that, the custom key can be used only with the coins that are stopped in the return coin passage. It is possible to easily perform a door locking and unlocking of any number of times I.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure is a system main body of a key system according to the present invention in a coin locker. As shown in FIG. 1 and subsequent figures, a custom key insertion cylinder 28, a master key insertion cylinder 29 having a master cam 31 linked to a slide frame 30, a reset push pin 12, a coin insertion slot 26, and a coin return slot 27 are provided. The left side frame 3 separated by the coin mechanical frame 7 to form the front frame 2, the paid coin passage 8 and the deposit coin passage 9 leading from the coin insertion slot 26, and slides facing the left side frame 3. A coin locker is formed on the right side of the front frame 2 on which the frame 30 is arranged. It is constituted by the right side frame 4 which is fixed to the rocker opening edge opposite the handle side of the door.

  Further, as shown in FIG. 7, on the rear side of the coin insertion slot 26, a selector arm 24 which can be rotated with one end as a fulcrum, and a state where the tip end side of the selector arm 24 is engaged can be rotated. When a coin P is inserted from the coin insertion slot 26, for example, in the case of a large-diameter coin P such as a 500-yen coin, the insertion slot at the entrance For example, in the case of a small-diameter coin P such as a 1-yen coin, the coin is restricted at the front end side of the link plate 25 and does not enter. Only the coin P of an appropriate size with a 100-yen coin inserted from the coin insertion slot 26 pushes up the selector arm 24 around the fulcrum, and the tip of the selector arm 24 is one end side of the V-shaped arm of the link plate 25. The other end side of the substantially V-shaped arm is pushed upward and retracted integrally with the pivoting of the coin P so that the coin P passes therethrough.

  On the upper surface of the coin mechanical frame 7, a passage switching lever 10 that can be swung by both side support portions is inclined, and protrusions 10 a, 10 b that protrude from the rear sides of both ends of the passage switching lever 10 are provided. The pay coin passage 8 and the deposit coin passage 9 are made to face the pay coin passage 8 and the deposit coin passage 9 through holes formed in the coin mechanical frame 7 so as to correspond to the pay coin passage 8 and the deposit coin passage 9, respectively. Thereby, the coin P inserted from the coin insertion slot 26 is first guided to the pay coin passage 8 side by a predetermined number, and when the last coin P enters the pay coin passage 8, one protrusion of the passage switching lever 10 is provided. 10b is pushed and retracted by the surface of the coin P, and at the same time, the other protrusion 10a is also retracted together, so that the coin P further inserted from the coin insertion slot 26 is the last coin P of the payable number. Is detected and guided to the deposit coin passage 9 side.

  Further, in parallel with the passage switching lever 10, a surplus coin insertion preventing lever 11 that can be swung by both side support portions is disposed on the upper surface of the coin mechanical frame 7. Protrusions 11 a and 11 b protruding in opposite directions are inserted into the deposit coin passage 9 through holes formed in the coin mechanical frame 7 so as to correspond to the upper and lower portions of the deposit coin passage 9. By the lever operation of the prevention lever 11, it is made to face alternately up and down.

  As a result, when the last coin P enters the deposit coin passage 9, the lower protrusion 11b of the surplus coin insertion preventing lever 11 is pushed by the surface of the coin P and retracted from the deposit coin passage 9, and at the same time the other protrusion 11a. Is inserted into the deposit coin passage 9 by the lever operation of the extra coin insertion prevention lever 11 so that no more coins P can be inserted from the coin insertion slot 26.

  The latch lever bracket 18 of the custom key insertion cylinder 28 is unlocked when the door checker plate (projecting on the surface of the front frame 2) when the door is closed is pushed and the latch lever bracket 18 is unlocked. The custom key Q inserted into the key insertion cylinder 28 is rotatable in either the locking direction in which the latch L protrudes or the unlocking direction in which the latch L retracts.

  Also, on the rear end side of the latch lever bracket 18, there is an engagement / disengagement pin 19 that is pushed and protrudes rearward when the custom key Q is inserted into the locked custom key insertion cylinder 28. When the engagement / disengagement pin 22 is pushed by the engagement / disengagement pin 19, the required position of the number switching plate 23 is closed to the coin mechanical frame 7 side, and the coin stop provided on the number switching plate 23 is disposed. The tip of the screw 23a is inserted into the pay coin passage 8 from a hole formed in the coin mechanical frame 7 along the pay coin passage 8 to prevent the coin P from falling.

  Then, by pulling out the custom key Q from the custom key insertion cylinder 28 in the locked state, the engagement / disengagement pin 19 is retracted, and the number changeover plate 23 is urged by its own spring through the engagement / disengagement plate 22. The coin stop screw 23a is opened from the in-mechanical frame 7 and the tip of the coin stop screw 23a is detached from the hole so that the coin P in the pay coin passage 8 is dropped into a collecting box (not shown) on the lower side. That is, at the stage where the custom key Q is pulled out from the custom key insertion cylinder 28 after the first locking, all the coins P in the pay coin passage 8 have already fallen into the lower collection box. Therefore, the coin P in the pay coin passage 8 is opened and dropped by the pressing operation of the reset push pin 12 as in the conventional key system due to the second and subsequent unlocking / unlocking. It is impossible in the first place.

  The positions of the holes formed along the pay coin passage 8 and the coin stop screws 23a attached to the number switching plate 23 corresponding to the holes correspond to the number of coins P held in the pay coin passage 8. In response to this, a predetermined interval is set in the vertical direction. That is, as shown in FIG. 12, in the case of a configuration in which three coins are held in the pay coin passage 8 and one coin coin P is held in the deposit coin passage 9, the last three The coin stop corresponding to the midway position of the pay coin passage 8 where the first coin P is locked by the coin stop screw so that the first coin P comes to the position of the one protrusion 10b of the passage switching lever 10 A screw 23a is attached. At this time, the fourth coin P is introduced into the deposit coin passage 9 by the detection of the passage switching lever 10.

  In addition, as shown in FIG. 13, when the pay coin path 8 is configured to hold five 100 coins P and the deposit coin path 9 holds two 100 coins P, Correspond to the lowermost position of the pay coin path 8 where the first coin P is locked by a coin stop screw so that the fifth coin P is positioned at the position of one projection 10b of the path switching lever 10. A coin stop screw 23a is attached. At this time, the sixth and seventh coins P are introduced into the deposit coin passage 9 by the detection of the passage switching lever 10.

  The peripheral side surface of the latch lever bracket 18 protrudes on one side in the axial direction, and a string-wound spring is suspended from one side at the tip of the latch lever bracket 18 so that the latch lever bracket 18 itself is always in the unlocking direction in which the latch L retracts. The rotation is energized. Further, on the other side surface in the axial direction at the tip of the latch lever bracket 18, a coin checker 20 urged to rotate in one rotation direction (counterclockwise in the figure) via a string spring, and the coin checker 20 A checker stopper 21 that is coaxial and swingable in both the left and right rotational directions is pivotally mounted.

  Thus, when the coin P is stopped in the deposit coin passage 9, the tip of the coin checker 20 is pushed by the surface of the coin P and retracted from the deposit coin passage 9, and the custom key Q of the latch lever bracket 18. Rotation in the locking direction by is allowed. At this time, the coin P is locked by the coin stop screw 16 a of the return stop bracket 16 protruding into the deposit coin passage 9.

  The tip of the checker stopper 21 is bifurcated so as to sandwich the engagement / disengagement pin 19, and the engagement / disengagement pin 19 is moved forward and backward by pushing or pulling the custom key Q inserted into the custom key insertion cylinder 28. Accordingly, the tip of the checker stopper 21 swings back and forth.

  That is, after locking with the custom key Q, when the key Q is pulled out, the upper edge of the checker stopper 21 is locked by a locking claw (not shown) provided at the upper end of the coin checker 20, whereas the unlocking is performed. As the engagement / disengagement pin 19 advances by pushing the custom key Q for the checker, the checker stopper 21 swings forward and is detached from the locking claw of the conchecker 20. As a result, the custom key Q is allowed to rotate in the unlocking direction, and the latch L is disengaged from the rocker body.

  The tip of the reset push pin 12 is connected to one end side of a return arm 13 that can swing back and forth via a central fulcrum portion via a coil spring, and the other end side of the return arm 13 is connected to the other end side of the return arm 13. An L-shaped return leaf spring 14 is attached. The front end of the return leaf spring 14 is arranged so as to be able to open and close with respect to the coin mechanical frame 7 and is erected vertically at the rear end of the return stop bracket 16 urged in the closing direction by the spring. It is engaged with the piece 16a.

  Further, as shown in FIGS. 2, 5, and 10, a return coin temporary fixing lever 17 is rotatably attached to the rotation shaft side of the number changeover plate 23, and the return coin temporary fixing lever 17 lower side A protrusion 17a protruding from one end of the return stop bracket 16 is placed on the upper surface of the return stop bracket 16 opposite to the locking piece 16a (front end side), and a protrusion 17b protruding from the other end on the upper side is charged for the passage switching lever 10. It is arranged on the notch of the protrusion 10b on the coin passage 8 side.

  When the coin P is stopped on the pay coin path 8 side, the projection 10b of the path switching lever 10 is pushed up by the coin P together with the projection 17b of the return coin temporary stop lever 17, and the other of the return coin temporary stop lever 17 is pushed. The return stop bracket 16 is locked by the projection 17a and prevents the return stop bracket 16 from moving in the opening direction, so that the coin stop screw 16b of the return stop bracket 16 can be used even when the reset push pin 12 is pressed. The coin P in the deposit coin passage 9 is not dropped into the coin return slot 27 while maintaining the state of being inserted into the coin 9.

  In addition, a protrusion 18a is provided on the other side (downward position) of the peripheral side surface of the latch lever bracket 18, and locking pins 18b and 18c are protruded from the base end and lower end of the protrusion 18a. .

  Of these, the locking pin 18b of the protrusion 18a is freely engageable / removable with respect to the return stopper 15. At the locking rotation position of the latch lever bracket 18 by the custom key Q, the locking pin 18b is connected to the return stop bracket. By preventing the return stop bracket 16 from rotating in the opening direction via the 16 locking pieces 16a and maintaining the closed state at all times, the coin stop screw 16b of the return stop bracket 16 is used to keep the deposit coin passage 9 inside. The coin P is kept stationary. As a result, even if the user accidentally presses the reset push pin 12 while the custom key Q is locked, the return leaf spring 14 is locked to the return stop bracket 16 to prevent rotation in the opening direction. Therefore, the coin P stopped in the deposit coin passage 9 is held so as not to fall into the coin return port 27.

  On the other hand, in the unlocking rotation position of the latch lever bracket 18 by the custom key Q, the lock of the return stop bracket 16 to the lock piece 16a by the lock pin 18b of the protrusion 18 is released, and the return lock bracket 16 is opened in the opening direction. In order to allow the rotation of the return stop bracket 16, the return stop bracket 16 is rotated in the opening direction via the return arm 13, and the coin stop screw 16 b of the return stop bracket 16 is removed from the deposit coin passage 9. The coin P that has been stopped in the deposit coin passage 9 is dropped into the coin return slot 27 by being retracted.

  Further, at the locking position of the latch lever bracket 18 by the custom key Q, the locking pin 18c provided at the tip of the projection 18a is locked to the projection 15a provided at the base end of the return stopper 15 and this is shown in FIG. The shield 15 b provided at the base end of the return stopper 15 is caused to face the coin return slot 27 by rotating in the clockwise direction. As a result, the coin return port 27 is closed, and it is possible to prevent withdrawal of the coin P that is stopped.

  Next, an example of use and operation of the best mode configured as described above will be described. First, after opening the coin locker door, the luggage is put into the locker, and the coin insertion slot 26 of the system main body 1 is inserted. Insert a predetermined number of coins P. At this time, since the custom key Q is inserted into the custom key insertion cylinder 28, the engagement / disengagement plate 22 is pushed by the engagement / disengagement pin 19 that is pressed and protrudes rearward, whereby the number change plate 23 is changed. A coin stop screw 23a, which is closed on the coin mechanical frame 7 side and provided on the number switching plate 23, is plunged into the paid coin passage 8 from a hole formed in the coin mechanical frame 7 along the paid coin passage 8. This prevents the coin P from falling.

  As shown in FIG. 12, when the pay coin path 8 is configured to hold three 100 coins and the deposit coin path 9 holds one 100 coins P, The coin P is locked by the coin stop screw 23 a, and the last third coin P comes to the position of one protrusion 10 b of the path switching lever 10. Then, the fourth coin P is introduced into the deposit coin passage 9 by the detection of the passage switching lever 10.

  In addition, as shown in FIG. 13, when configured with a specification in which five coins are held in the pay coin passage 8 and two coins P are held in the deposit coin passage 9, The coin P of the eye is locked by the coin stop screw 23 a, and the last fifth coin P comes to the position of one protrusion 10 b of the path switching lever 10. Then, the sixth and seventh two coins P are introduced into the deposit coin passage 9 by the detection of the passage switching lever 10. The coin P is locked by a coin stop screw 16 a of a return stop bracket 16 protruding into the deposit coin passage 9.

  Further, when the coin P is stopped in the deposit coin passage 9, the tip side of the coin checker 20 is pushed by the surface of the coin P and retracted from the deposit coin passage 9, and the custom key of the latch lever bracket 18 is used. Rotation in the locking direction by Q is allowed.

  Then, when the custom key Q is pulled out from the custom key insertion cylinder 28 after the door is closed, the engagement / disengagement pin 19 is retracted, and the number switching plate 23 is urged by its own rotation via the engagement / disengagement plate 22. 7, the coin stop screw 23 a is removed from the hole, and the coin P that has stopped in the pay coin path 8 is dropped into a collection box (not shown) on the lower side.

  After that, while the coin P remains in the deposit coin passage 9, as long as the door checker plate is pushed by the door, the lock rotation or unlocking rotation of the custom key Q inserted in the custom key insertion cylinder 28 is performed. Can be done any number of times. Further, even if the user accidentally presses the reset push pin 12 in the locked state of the custom key Q, the coin P stopped in the deposit coin passage 9 is held so as not to fall into the coin return slot 27. The At this time, since the coin P in the pay coin passage 8 does not already exist, it is a matter of course that there is no relationship with the function of the reset push pin 12.

  When taking out the luggage from the coin locker, the custom key Q is inserted into the custom key insertion cylinder 28 and the custom key Q is rotated in the unlocking direction, whereby the latch L is retracted and the door is opened.

  When the coin locker is not finally used, the coin stop screw 16a of the return stop bracket 16 is retracted from the hole by pushing the reset push pin 12 while the custom key Q is rotated in the unlocking direction. The coin P that has stopped in the deposit coin passage 9 is dropped into the coin return slot 27.
