In the hanging part 322, a hook part 323 is formed at an extended end part thereof.

  The cylinder lever 33 has its own shaft on the inner cylinder of the key cylinder that rotates according to the locking and unlocking operation of the key inserted in the key insertion port (not shown) provided in front of the outer door 20. The outer cylinder of the key cylinder is fixed to the frame material of the outer door 20 so as to swing around the axis of the portion (the outer cylinder of the key cylinder is fixed to the frame material of the outer door 20). More specifically, the key is unlocked and moved upward by the unlocking operation of the key inserted into the key insertion slot, and is locked and moved downward by the key locking operation. The cylinder lever 33 has an elliptical portion 331, and a rod member 332 protrudes toward a hanging portion 322 of the connecting member 32 at a portion different from the shaft portion in the elliptical portion 331. The rod member 332 is located in the lower region of the horizontal portion 321 of the connecting member 32.

  The regulating member 34 is formed by appropriately bending a plate material such as a steel plate, and the axis of the regulating pin member 37 is a center axis of the frame member of the outer door 20 via the regulating pin member 37. It is arranged so that it can swing around. The regulating member 34 is formed with a groove portion 341 having an open lower portion and a weight portion 342, and the weight portion 342 is positioned at a restricting position as shown in FIG. When the restriction member 34 is positioned at the restriction position, the hook part 323 of the connecting member 32 is allowed to enter the groove part 341. That is, when the restriction member 34 is located at the restriction position, the groove 341 is located above the hook portion 323.

  A guide member 38 is interposed between the restriction member 34 and the cylinder lever 33. The guide member 38 is connected to the regulating member 34, and when the cylinder lever 33 is unlocked, it is brought into contact with a part of the peripheral edge of the elliptical portion 331 of the cylinder lever 33, as shown in FIG. In addition, the restricting member 34 located at the restricting position is swung upward against the gravity of the weight portion 342 and moved to the allowable position. Here, when the cylinder lever 33 is unlocked, before the rod member 332 of the cylinder lever 33 comes into contact with the lower surface of the horizontal portion 321 of the connecting member 32, one of the peripheral portions of the elliptical portion 331 of the cylinder lever 33 is set. It has been adjusted in advance so that the portion comes into contact with the guide member 38. Thereby, before the rod member 332 of the cylinder lever 33 comes into contact with the horizontal portion 321 of the connecting member 32, the restricting member 34 is positioned at the allowable position, and the hook portion 323 of the connecting member 32 is the groove portion of the restricting member 34. 341 will leave.

  In the vending machine to which the locking device having the above-described configuration is applied, operations such as product replenishment can be performed inside the main body cabinet 1 as follows.

  First, the state where the outer door 20 closes the front opening of the main body cabinet 1 will be described from the case where the lock device holds the state. In such a case, the slider 31 constituting the lock device is located at the lock position and engaged with the lock member R, and the restriction member 34 is located at the restriction position.

  In such a case, an unsafe third party turns the anti-theft plate 24 (see FIG. 5) of the outer door 20 and inserts foreign matter into the slider opening 3111 of the slider 31 located at the lock position to move the slider 31 upward. As shown in FIG. 8, the hook portion 323 of the connecting member 32 formed integrally with the slider 31 comes into contact with the restriction member 34 located at the restriction position as shown in FIG. It is restricted that 31 is slid upward further.

  Then, a key is inserted into the key insertion slot by a rootman who performs operations such as replenishment of goods to the vending machine, and the cylinder lever 33 is moved upward as shown in FIG. Move to unlock. When a part of the peripheral edge of the cylinder lever 33 that is unlocked in this way comes into contact with the guide member 38, the restricting member 34 swings from the restricting position toward the allowable position against the gravity of the weight part 342. . As a result, the hook portion 323 of the connecting member 32 is detached from the groove portion 341 of the regulating member 34. That is, when the regulating member 34 is located at the regulating position, the regulating member 34 regulates the upward displacement amount of the connecting member 32 and suppresses the slider 31 from sliding from the lock position to the release position. On the other hand, when the device itself is located at the allowable position, the displacement of the connecting member 32 is allowed.

  Thereafter, as shown in FIGS. 9 and 10, the rod member 332 of the cylinder lever 33 that moves to unlock is brought into contact with the lower surface of the horizontal portion 321 of the connecting member 32 and is pressed by the rod member 332 so that the connecting member 32 moves upward. As a result, the slider 31 integrally formed with the connecting member 32 also slides from the lock position toward the release position.

  Thus, when the slider 31 slides upward and is positioned at the release position, the hooking portion 3611 of the slider holding member 36 protrudes from the slider opening 3111 to the back surface side and engages with the upper edge portion of the slider opening 3111. At the same time, the slider 31 is held in a state of being positioned at the release position. When the slider 31 is held at the release position in this way, the engagement state with the lock member R is released.

  Here, the connecting member 32 includes a horizontal portion 321 and a hanging portion 322, and has a form in which a lower portion is opened. Therefore, even if the rootman locks the key to remove the key from the key insertion slot, as shown in FIGS. 11 and 12, the slider 31 is positioned at the release position and the cylinder lever 33 is moved downward. Allow locking movement.

  In other words, the connecting member 32 is disposed integrally with the slider 31, and when the cylinder lever 33 is unlocked, the connecting member 32 is abutted against the cylinder lever 33 to displace itself and lock the slider 31. When the cylinder lever 33 moves while being moved from the position to the unlocking position, the locking movement is always allowed.

  Since the connecting member 32 always permits the locking movement of the cylinder lever 33 in this way, the rootman pulls out the key from the key insertion port, and then opens the front door of the main body cabinet 1 by moving the outer door 20 open. It can be opened, and then the inner door 10 can be moved open to perform operations such as product replenishment.

  In this case, even when the cylinder lever 33 is locked and moved, the restricting member 34 is allowed by the contact of the tip of the hook portion 323 of the connecting member 32 formed integrally with the slider 31 positioned at the release position. Will be in position.

  Then, after performing operations such as product replenishment, the route man closes the outer door 20 and closes the front opening of the main body cabinet 1, whereby the lock member R of the main body cabinet 1 moves through the slider opening 3111. 31 enters the inside of the slider 31 and comes into contact with a contact portion 3621 formed on the base portion 362 of the slider holding member 36. As a result, the slider holding member 36 swings in a manner to be separated from the base 311 of the slider 31, and the engagement between the hook 3611 and the upper edge of the slider opening 3111 is released, and the slider 31 is lowered by its own weight. The slider 31 moves to the lower limit position, that is, the lock position, the upper edge of the slider opening 3111 contacts the lock member R, and the slider 31 engages with the lock member R at the lock position, so that the outer door The state which 20 closed the front opening of the main body cabinet 1 can be hold | maintained. That is, after the work such as product replenishment is performed, when the outer door 20 is closed and the front opening of the main body cabinet 1 is closed, the key is re-inserted into the key insertion slot and the unlocking operation is performed as before. There is no need to do etc.

  By the way, in the locking device described above, the slider 31 is integrally formed with the abutting piece 3122 at the extending end portion of one side portion 312 (the side portion 312 opposite to the open end of the outer door 20). A notch 3622 is formed in a region facing the contact piece 3122 in the base 362 of the slider holding member 36.

  As a result, in a state where the outer door 20 is in a state where the front opening of the main body cabinet 1 is closed, for example, an anti-theft plate 24 provided on the outer door 20 is turned around by an unsuspecting third party, for example, a driver or the like Even when the tool K, which is a long rod-shaped body, enters from the slider opening 3111, the tip of the tool K can be brought into contact with the contact piece 3122 as shown in FIG. Therefore, both the tip and the intermediate portion of the tool K are in contact with the slider 31 which is the same member, and even if the tool K is swung along the vertical direction with the tip as a fulcrum, for example, There is no possibility that the slider 31 is separated from the slider holding member 36 or the like and is slid from the lock position to the release position only by the deformation of the slider 31.

  As described above, according to the lock device of the vending machine according to the present embodiment, when the cylinder lever 33 is unlocked, the connecting member 32 is brought into contact with the cylinder lever 33. When the cylinder lever 33 is moved in a locked state while the slider 31 is moved from the locked position to the unlocked position by itself, the locked movement is always allowed. When the door 20 is closed, there is no need to reinsert the key into the key insertion slot, and operations such as product replenishment are not complicated. Further, when the restriction member 34 is located at the restriction position, the amount of upward displacement of the connecting member 32 is restricted to prevent the slider 31 from sliding from the lock position to the release position. On the other hand, since the displacement of the connecting member 32 is permitted when it is located at the permissible position, the anti-theft in the case where the outer door 20 holds the front opening of the main body cabinet 1 closed. The sex is secured. Accordingly, the anti-theft property can be ensured satisfactorily while improving the efficiency of operations such as product replenishment.

  Further, according to the above locking device, even when the tool K or the like enters from the slider opening 3111, the tip of the tool K or the like abuts on the abutting piece 3122 formed integrally with the slider 31. There is no possibility that the slider 31 is separated from the slider holding member 36 and the like and is slid from the lock position to the release position, and thus the slider 31 can be prevented from moving from the lock position toward the release position.

  As described above, the lock device for a vending machine according to the present invention is useful for maintaining a state in which the door body closes the front opening of the vending machine main body.
