Description

  The present invention relates to an electronic lock structure of a money handling device including a change device such as a vending machine.

  Since the money handling machine handles money, the safe part and its door are firmly manufactured. In the general structure of a safe, a key hole for inserting a key from the outside is formed at an appropriate position of a door, and a lock mechanism is provided inside. The lock is unlocked by inserting the key into the keyhole and turning, and conversely, it is locked when the door is closed. This type of safe has a low anti-theft property because the keyhole portion of the lock can be seen from the outside, and the site to be broken at the time of theft can be easily understood. Moreover, since the back side of the keyhole and the lock mechanism are always connected, the door can be easily opened by breaking the keyhole portion.

  Patent Document 1 describes an electronic lock that opens and closes a box for small items in a vehicle, for example, instead of a mechanical lock. This electronic lock includes an operation button whose box is locked by a lock lever and operable from the outside, and a case having an unlocking mechanism that operates in conjunction with the depression of the operation button. The case is provided with an operation lever that is interlocked with the pressing of the operation button, an electromagnet integrated with the operation lever, and a lock release lever that can be attracted to the electromagnet. When the unlocking lever is operated, it unlocks the locking lever. In this structure, in the case of a proper unlocking operation in which the electromagnet is fed, the unlocking lever attracted by the electromagnet moves to unlock the lock lever, while the electromagnet is not fed, for example, an illegal unlocking operation. During the lock operation, the lock release lever is not attracted to the electromagnet, so the lock release lever cannot move and the lock lever cannot be unlocked. In such an electronic lock, the keyhole is not provided on the surface of the open / close door of the box, and the electromagnet is interposed between the operation button and the lock release lever, so that the unlocking cannot be performed only by operating the operation button. There is an advantage in preventing fraud.

JP 2010-77614 A

  However, according to the electronic lock described in Patent Document 1, since the operation button and the operation lever are interlocking and the operation lever of the unlocking mechanism and the electromagnet are integrated, the electromagnet is not supplied with power. However, there is a problem that the electromagnet must always be moved by pressing the operation button. In addition, since the mechanism uses the magnetic attraction force of the electromagnet to move the lock release lever to contact the lock lever and unlock it, electromagnetic force, that is, electric power may be required for the mechanism size.

The present invention was made in view of the above, and provided with an unlocking lever instead of a keyhole on the outside, and at the normal time has an antitheft effect in which the unlocking lever is opened without being connected to the internal locking mechanism. An object is to provide a high electronic lock structure.

  The present invention provides an electronic lock structure of a burglar door that locks and unlocks the case with an engagement portion of the case, and is provided to be exposed on the outer surface side of the burglar door. And a connecting part that is an action part located inside the anti-theft door through a hole formed in the anti-theft door, and the connecting part is fixed to the inside of the anti-theft door. An unlocking lever that passes through a long slot in a predetermined direction formed in the base and protrudes inward, and moves from one side to the other side of the slot according to the operation, Supported on the inner side, and is movable between a connection position engaging with the connection part when the connection part is on the one side of the elongated hole and a non-connection position spaced apart from the connection position, and In a state where the connecting portion is engaged with the connecting portion, the connecting portion is interlocked with the movement from the one side to the other side. A connected member that moves from the first position to the second position, and supported by the connected member, and in conjunction with the movement of the connected member from the first position to the second position, A first key cam that moves from a first locked position with a first engaging portion of the body to a first unlocked position separated from the first engaging portion of the housing; and the connected member. And an electromechanical force conversion member that is positioned at the unconnected position when the power is shut off and moved to the connected position when the power is supplied.

  According to the present invention, when the power is shut off, the connected member is located at the non-connected position, and therefore does not engage with the unlocking lever. Therefore, since the unlocking lever is not connected to the locking mechanism such as the connected member or the first key cam, even if the unlocking lever is operated, only the unlocking lever moves. On the other hand, when the power is supplied, since the connected member is located at the connecting position and engages with the unlocking lever, the unlocking lever is connected to the connected mechanism or the lock mechanism such as the first key cam, for unlocking. When the lever is operated, the first key cam moves to the first unlock position, and the anti-theft door is unlocked. In addition, since no keyhole is provided outside the anti-theft door, it is difficult to understand the location to be broken, and it is also difficult to break the lock.

  The unlocking lever is provided on a vertical portion of a side surface of the anti-theft door. According to this configuration, since the operation member is not provided in addition to the keyhole on the front face of the security door, it is more preferable in terms of crime prevention.

  The second locking with the second engagement portion of the housing is supported by the connected member and interlocked with the movement of the connected member from the first position to the second position. A second key cam that moves from a position to a second unlocked position separated from the second engaging portion of the housing; the connected member is long and includes a rotation shaft at an intermediate position; The first key cam is supported on one side across the rotation shaft, and the second key cam is supported on the other side. The second key cam is configured such that the first key cam is moved from the first locking position. In conjunction with the movement to the first unlocked position, the second unlocked position moves to the second unlocked position. According to this configuration, since the first and second key cams are provided on both sides of the rotating shaft of the connected member, locking can be performed on opposite sides of the anti-theft door, and further anti-theft can be achieved. .

  The electromechanical force conversion member is an electromagnetic solenoid. According to this configuration, the unlocking process can be performed only with or without energization.

According to the present invention, an unlocking lever is provided on the outside instead of the keyhole, and the unlocking lever is normally connected to the inner locking mechanism without being connected to the inner locking mechanism. Anti-theft effect is obtained.

It is a block diagram which operates an electromagnetic solenoid.

  In FIG. 1, a money handling device 100 such as a changer installed in a vending machine includes a safe 101 having an opening on the front side and an exterior part 102 covering the front side. The safe 101 includes a money storage unit 103 therein, and money (change) is paid out to the payout opening 104 by a money withdrawal processing unit (not shown) provided in the money storage unit 103 and the exterior unit 102. An anti-theft door 2 (see FIG. 2) is provided inside the exterior portion 102 between the opening on the front side of the safe 101, and the exterior portion 102 surrounds the anti-theft door 2.

  Although details will be described in FIG. 2 and subsequent figures, the anti-theft door 2 is provided with a lock mechanism portion for locking and unlocking the opening on the front side of the safe 101. Further, an opening 1021 is formed at an appropriate position on the side of the exterior portion 102, and the unlocking lever 1 is swingably attached to the opening 1021.

  In FIG. 2, an anti-theft door 2 is an engagement portion 101a (a recess, a groove, a hole, a hole, etc.) formed on the left and right sides of the front side (left side in FIG. 1), for example, on the inner wall of the safe 101 in FIG. On the other hand, as will be described later, the key cams 5 and 6 of FIG. 2 are locked when they are fitted, and are unlocked when the fitting is released. In the unlocked state, the anti-theft door 2 can be opened, or as another aspect, the anti-theft door 2 can be pulled out together with the money storage part 103 from the safe 101 to the front side.

  The anti-theft door 2 has a predetermined shape, a rectangular parallelepiped disk-like body, and is provided with a small opening for money passage and other uses as necessary (the upper and lower sides of FIG. 2 (e), etc.). (See the rectangle). Further, the anti-theft door 2 has an upright portion 21 in which the edges of the four sides are erected by a predetermined dimension in order to reinforce the strength and protect the mounted mechanism.

  The unlocking lever 1 is swingably supported in a hole facing the anti-theft door 2 through a vertically long opening 1021 formed in the side wall of the exterior portion 102. The unlocking lever 1 is pivotally supported by a pivot shaft 11 that stands upright on the inner side of the inner anti-theft door 2 (the surface shown in FIG. 2E). The unlocking lever 1 has a vertical posture that is substantially flush with the side surface of the exterior portion 102 in an open state in which no external force is applied, and rotates when the upper operation portion 12 (see FIG. 2B) is pressed. It swings around the shaft 11 to be inclined as shown in FIG. A pin 13 as a connecting member is planted on the unlocking lever 1 toward the anti-theft door 2 side. As will be described later, the pin 13 is fitted in a long hole 34 that is long in the left-right direction and is formed at a position where both the anti-theft door 2 and the support base 3 face each other. In FIG. 2, only the long hole 34 of the support base 3 is visible. The hole on the anti-theft door 2 side should be at least equal to or larger than the long hole 34.

  The support base 3 has a rectangular parallelepiped shape that is smaller than the anti-theft door 2 and is arranged in parallel at a suitable position on the front side of the anti-theft door 2, in the vertical center of FIG. In other words, it is fixed by a fastener (not shown) such as a bolt. Upright portions 31 and 311 are formed at required portions on the left and right sides of the support base 3. The vertical portions 31 and 311 have a guide hole 32 through which key cams 5 and 6 described later pass, a guide hole 22 (see FIG. 2D) of the vertical portion 21, and a guide hole formed at a position facing the guide hole. (Not visible in the figure). Further, as will be described later, the support base 3 is provided with a rotating shaft 33 that pivotally supports the unlocking connection angle 4 and pins 35 and 36 that guide the slide of the key cams 5 and 6. Yes.

  On the front side of the support base 3 (see FIG. 2 (c)), in addition to the support base 3, an unlocking connection angle 4, key cams 5, 6 and an electromagnetic solenoid 7 are disposed as a lock mechanism.

  The unlocking connection angle 4 has an elongated shape in the up-down direction, and a fitting portion 41 as a connected member that is split into two for connecting to the pin 13 is formed at the upper end. The shapes of the connecting member and the connected member may be reversed. A pin 42 is erected at an appropriate position above the unlocking connection angle 4. The pin 42 is fitted in a long hole 53 that is formed in the key cam 5 in the vertical direction. An elongated hole 43 that is elongated in the vertical direction is formed at the approximate center in the vertical direction of the unlocking connection angle 4. The long shaft 43 is fitted with a rotating shaft 33 upright on the support base 3. The unlocking connection angle 4 is movable in the vertical direction by the dimension of the long hole 43 on the front surface of the support base 3 because the rotation shaft 33 is fitted in the long hole 43, and the rotation shaft 33. It can be turned around. A pin 44 is erected at an appropriate position below the unlocking connection angle 4. The pin 44 is fitted in a long hole 63 that is formed in the key cam 6 and that is elongated in the vertical direction. The pins 42 and 44 and the rotating shaft 33 are provided with washers for preventing the removal as necessary. The movement and rotation of the unlocking connection angle 4 will be described later.

  The key cam 5 has a flat plate shape, and a projecting piece 51 extending through the guide hole 32 is provided at the left end. In addition, a long notch 52 is formed in the right side of the key cam 5 from the right end in the lateral direction. A pin 35 erected on the support base 3 is fitted into the notch 52. The key cam 5 is supported by a guide hole 32 and a pin 35 so as to be movable in the left-right direction. An urging member 45 is interposed between the pin 53 and the unlocking connection angle 4 so that the unlocking connection angle 4 is not accidentally moved upward by a force other than the electromagnetic solenoid 7.

  The unlocking connection angle 4 is allowed to move in the vertical direction by the length of the long hole 53 because the pin 42 is fitted in the long hole 53 formed in the key cam 5 in the vertical direction. When the unlocking connection angle 4 moves to the upper connection position, the fitting portion 41 is fitted to the pin 13. When the operating portion 12 of the unlocking lever 1 is pushed from the outside in this fitted state, the unlocking connection angle 4 rotates clockwise in FIG. 2C, and the key cam 5 is rotated by this rotation. Move to the right. The pin 42 moves up and down during this rotation, and this movement is absorbed by the long hole 53. As a result, the protruding piece 51 is separated (immersed) from the engagement portion 101a (not shown) on the side of the safe 101 described above, and is in a so-called unlocked state.

  On the other hand, when the fitting portion 41 is not moved to the upper connecting position side and is not fitted with the pin 13, even if the operation portion 12 of the unlocking lever 1 is pushed from the outside, only the pin 13 is In FIG. 2 (c), the key cam 5 does not move only by rotating in the clockwise direction, and the projecting piece 51 does not separate from the engagement portion 101 a (not shown) on the side of the safe 101. The key cam 5 is formed with an opening 54 for preventing interference with the pin 13 as necessary.

  The key cam 6 has a plate-like body that is long in the horizontal direction, and a long hole 62 that is long in the horizontal direction for fitting the pin 36 at an appropriate position on the left side is formed. Further, the right end portion 61 of the key cam 6 passes through a guide hole 22 (a guide hole on the upright portion 31 side is not visible) formed at a position facing each other in both the upright portion 31 and the upright portion 21. Therefore, the key cam 6 is supported by the guide hole 22 and the pin 36 and the pin 36 so as to be movable in the left-right direction.

  When the operation part 12 of the unlocking lever 1 is pushed in from the outside in a state where the unlocking connection angle 4 is moved upward and the fitting part 41 is fitted to the pin 13, the unlocking connection angle 4 becomes as shown in FIG. In (c), it rotates clockwise, and the key cam 6 moves to the left by this rotation. The pin 44 moves up and down during this rotation, and this movement is absorbed by the long hole 63. As a result, the right end portion 61 of the key cam 6 is separated (immersed) from the engagement portion (not shown) on the side portion of the safe 101 described above, and is in a so-called unlocked state.

  On the other hand, in a state where the fitting portion 41 is not moved to the upper coupling position and is not in the coupling position with the pin 13, even if the operation portion 12 of the unlocking lever 1 is pushed from the outside, the pin 2 only rotates in the clockwise direction in FIG. 2C, the key cam 6 does not move, and the right end 61 of the key cam 6 is separated from the engagement portion (not shown) on the side of the safe 101. There is no.

  The electromagnetic solenoid 7 functions as an electromechanical force conversion mechanism, and raises and lowers the unlocking connection angle 4 using electric force. 2 (c), the electromagnetic solenoid is not operating, and the unlocking connection angle 4 is in the lower non-connection position, and FIG. 3 is the electromagnetic solenoid operating, and the unlocking connection angle 4 is in the upper connection position. The state in the position is shown.

  The electromagnetic solenoid 7 has a plunger 71 that moves forward and backward from the upper part of the main body in the protruding and retracting direction. The plunger 71 is in the upper protruding position (see FIG. 2C) when in an open state, that is, when not energized, and in the lower retracted position (see FIG. 3) when energized. A swing arm 73 is pivotally supported at the tip of the plunger 71 via a connecting shaft 72 so as to be rotatable on the surface of the support base 3. The connecting shaft 72 is fitted in a long hole (see FIG. 3) at the base end of the swing arm 73. The swing arm 73 is pivotally supported by a pivot shaft 74 upright on the support base 3 at a substantially intermediate position, and can swing around the pivot shaft 74. Further, the swing arm 73 is rotatably connected to the unlocking connection angle 4 by a connecting shaft 45 that passes through a long hole (see FIG. 3) at the tip thereof. As a result, the vertical position (connected position and non-connected position) of the unlocking connection angle 4 can be changed corresponding to the position of the plunger 71.

  In the block diagram of FIG. 5, the power source 201 supplies power for driving the plunger 71 of the electromagnetic solenoid 7. The unlocking instruction unit 202 is provided on the management processing side of the money handling device 100, and is configured to energize the electromagnetic solenoid 7 from the power source 201 when preset code information is input. Note that instead of the predetermined code, an operation button for instruction may be operated. Further, a switch may be interposed between the power source 201 and the electromagnetic solenoid 7, and this switch may be connected / disconnected by a signal from the unlock instruction unit 202.

  Next, unlocking and locking operations will be described with reference to FIGS. First, in a state where the electromagnetic solenoid 7 is not energized, the plunger 71 of the electromagnetic solenoid 7 is in the upward projecting position as shown in FIG. Therefore, the fitting part 41 at the upper end of the unlocking connection angle 4 is not connected (not connected) to the pin 13 as shown in the partial enlarged view of FIG. It is in. In this state, even if the operation part 12 of the unlocking lever 1 is pushed in, only the pin 13 moves left and right within the long hole 34. At this time, the protruding piece 51 of the key cam 5 is engaged with the engaging portion 101a. Therefore, unlocking cannot be performed only by operating the unlocking lever 1. In addition, since only the unlocking lever 1 becomes a load at the time of pushing, there is no feeling of reaction to the operator, and no expectation of unlocking is given.

  Next, a case where the electromagnetic solenoid 7 is energized will be described. In this state, the plunger 71 of the electromagnetic solenoid 7 is in the downward retracted position as shown in FIG. 2, and the unlocking connection angle 4 is moved to the upper connection position. Therefore, the fitting part 41 at the upper end of the unlocking connection angle 4 is connected to the pin 13 as shown in the partial enlarged view of FIG. In this state, when the unlocking lever 1 is pushed in, the pin 13 moves in the right direction (see FIG. 4B), and in conjunction with this movement, the unlocking connection angle 4 is centered on the rotation shaft 33. Rotate clockwise. Further, by this turning operation, the pin 42 pushes the long hole 53 to the right, and the key cam 5 moves to the right as shown by the arrow in FIG. As the key cam 5 moves in the right direction, the projecting piece 51 is released from the engaged state with the engaging portion 101a and unlocked.

  Further, by the clockwise rotation of the unlocking connection angle 4, the key cam 6 moves to the left, which is the opposite direction to the key cam 5, and the right end 61 is separated from the engaging portion of the safe 101. Locked. As described above, the protrusion 51 and the right end 61 of the key cams 5 and 6 are separated from the engaging portions 101a and the like on both sides of the safe 101, whereby unlocking is performed. In this state, the anti-theft door 2 can be pulled out.

  When the safe 101 is closed after unlocking, the protrusions 51 and the right end 61 of the key cams 5 and 6 cannot be closed unless they interfere with the side wall of the safe 101. Therefore, before closing, the electromagnetic solenoid 7 is energized, and the unlocking lever 1 is pushed in so that the protrusion 51 and the right end 61 of the key cams 5 and 6 are shifted to the immersive state. By shutting off the energization of the solenoid 7, the plunger 71 returns to the open position (see FIG. 1C) and the locking is completed. Alternatively, at least one of the projecting piece 51 and the right end portion 61 of the key cams 5 and 6 and the contact portion of the side wall of the safe 101 is formed in a taper surface at a contact position when closing, and the taper surface is obliquely applied during the closing. There may be a so-called clutch mode in which the protrusion 51 and the right end 61 are pushed in with the components and temporarily moved in the immersion direction, and various other locking methods are conceivable.

  In addition, although 1st Embodiment was set as the electronic lock structure of the mechanism locked on both the right and left sides using the key cams 5 and 6, the aspect using only the key cam 5 may be sufficient as 2nd Embodiment.

  In the first embodiment, the unlocking lever 1 is an electronic lock structure having a long structure that swings around the rotation shaft 11. However, as the third embodiment, the unlocking lever 1 is simply attached outward. It may be a pushed-in push button type structure.

  In the first embodiment, the unlocking lever 1 is provided on the side surface of the anti-theft door 2, but it may be provided at an appropriate position on the front side. Further, the pin 13 may be upright so as to penetrate the support base 3 between the anti-theft door 2 and the support base 3.

  In addition, the description of the above-described embodiment is an example in all respects, and should be considered not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
