Description

  The present invention relates to an electric lock that is locked and unlocked using a self-holding solenoid.

  Conventionally, for example, in a locker, when the door of the locker is closed to the main body, the hook of the door engages with the latch of the main body, the latch rotates to the locked position, and the latch moves by a self-holding solenoid. It is known to use an electric lock that locks a latch in a locked position with a stopper. The direction in which the latch rotates and the direction in which the latch stopper moves by the solenoid are in a crossing relationship (for example, see Patent Document 1).

  In an electric lock used for such a locker, the locked state or the unlocked state needs to be maintained for a long time, so that it is stable at two positions of the locked state and the unlocked state, and only when the solenoid is driven. A self-holding solenoid that does not need to be energized in a stable state is required.

When the electric lock is locked or unlocked, the state of the solenoid is switched by transmitting a lock signal or an unlock signal pulse from the control unit to the solenoid.
Japanese Utility Model Publication No. 8-10141 (page 2-3, FIG. 1-5)

  By the way, when a large volume of luggage is pushed into the locker and this luggage is pushed back to the door side, or a heavy luggage falls to the door side, the locker door is biased in the opening direction while being locked. The At this time, a force that rotates in the unlocking direction is applied to the latch of the electric lock via the door hook, and the latch is pressed against the latch stopper from the crossing direction.

  Therefore, when the user tries to take out the load, even if the lock signal is transmitted from the locker control unit to the electric lock and the solenoid is driven in the unlocking direction, the latch and the latch stopper which are in a crossing positional relationship. A strong frictional force may be generated between them and the solenoid may not operate normally.

  In such a case, when the user pushes the door back in the closing direction, the engagement between the latch and the latch stopper is released, but the timing for pushing the door back and a pulse of the unlock signal are transmitted to drive the solenoid in the releasing direction. If the timing does not match, there is a problem that the solenoid does not operate normally and the electric lock cannot be unlocked.

  In addition, a solenoid having a driving force larger than the frictional force between the latch and the latch stopper may be employed. However, in that case, there are problems such as an increase in the size of the solenoid itself and an increase in the capacity of the driving power.

  The present invention has been made in view of these points, and an object of the present invention is to provide an electric lock that can be reliably unlocked even when an unreasonable force is applied in the unlocking direction to a locked lock member. .

The electric lock according to claim 1 is a lock member provided to be rotatable between a locking angle and an unlocking angle, and a main driving member and a driven member provided to be movable between a locking position and an unlocking position, respectively. The locking member is held at the locking angle when the driven member is located at the locking position, and when the driven member is located at the unlocking position, the locking member is allowed to rotate, and the main driving member moves to the locking position. A stopper body that pushes the driven member to the locking position only by the main driving member, a self-holding type solenoid that directly drives and moves the main driving member and holds it in the locking position and the unlocking position, and the main driving member Between the locking member and the driven member, and a biasing member that is connected between the locking member and the driven member, and biases the driven member toward the unlocked position with respect to the main driving member that moves to the unlocked position. Lo In conjunction with the rotation of the member is arranged to be movable in a direction intersecting the moving direction of the driven member, in contact with the driven member of the locking position and interlocking member for holding the locking member in the locking angle It is equipped.

The electric lock according to claim 2 is the electric lock according to claim 1, wherein the direction in which the lock member moves from the locking angle to the unlocking angle and the direction in which the main driving member and the driven member move by the solenoid intersect. Is .

According to the electric lock of the first aspect, even if an unreasonable force is applied in the unlocking direction to the lock member in the locked state, the self-holding solenoid moves the main driving member to the unlock position. Further, the urging means connected to the main driving member that moves to the unlocking position urges the driven member in the unlocking position direction, and an unreasonable force in the unlocking direction against the lock member is generated. If released, the biasing means can move the driven member to the unlocked position and allow the lock member to rotate to the unlocking angle, so that the locking member in the unlocked state can be unlocked. Unreasonable force applied is not easily transmitted to the solenoid, and the solenoid can always operate normally and can be unlocked reliably. Further, the interlocking member arranged so as to be movable in a direction crossing the moving direction of the driven member in conjunction with the rotation of the locking member converts the rotation of the locking member into a linear slide movement, so that the locking position is reached. The locking member can be securely held at the locking angle by contacting the driven member. Further, even when an excessive force is applied in the unlocking direction to the lock member in the locked state, the interlocking member provided between the lock member and the sliding member serves as a cushioning material, and the transmission of an excessive force can be suppressed. .

According to the electric lock of the second aspect, in addition to the effect of the electric lock of the first aspect, there are a direction in which the lock member moves from the locking angle to the unlocking angle and a direction in which the main driving member and the driven member move by the solenoid. Due to the crossed positional relationship, the driven member may not move to the release position when an unreasonable force is applied in the unlocking direction to the locked member in the locked state. Normal operation can always be performed, and when an unreasonable force in the unlocking direction with respect to the lock member is released, the driven member moves to the release position and can be reliably unlocked .

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

A substantially U-shaped hook 26 protrudes from the right side portion which is the other side of the door 24, and a locking unit 27 as an electric lock is installed on the right side portion which is the other side of the housing chamber 16 in the main body 14. The hook 26 is engaged with the locking unit 27 so that the door 24 can be locked with the door 24 closed.

  The locking unit 27 of each storage chamber 16 is electrically connected to the control means 23 of the central control unit 15 and controlled centrally by the control means 23. The locking unit 27 and the control means 23 constitute an electric lock device 28.

  Next, FIGS. 1 to 6 show the structure of the locking unit 27 in the electric lock device 28.

  The locking unit 27 has a panel 31 installed on the front surface of the right side surface portion of the main body 14 and a base 32 fixed to the rear surface of the panel 31. The base 32 is formed in an L shape having a front plate portion 33 fixed to the rear surface of the panel 31 and a side plate portion 34 bent rearward from one side of the front plate portion 33.

  The panel 31 and the base 32 are formed with openings 35 and 36 into which the hooks 26 are inserted when the door 24 is closed.

  A locking lever 37 as a locking operation means is disposed on the front surface of the panel 31, and slide holes 38 and 39 through which the shaft portion 37a of the locking lever 37 is inserted along the vertical direction on the front plate portion 33 of the panel 31 and the base 32. Is formed. The locking lever 37 is movable in the vertical direction along the slide holes 38, 39 through which the shaft portion 37a is inserted, and the shaft portion 37a is in contact with the upper end or the lower end of the slide holes 38, 39 so that the vertical movement is possible. The unlocked position is defined as being in the upper position and the unlocked position is defined as being in the lower position.

  A cylinder lock 40 for manually unlocking using a key held by the administrator of the locker device 11 is provided on the front upper portion of the panel 31.

  Further, a lock member 44 is pivotally supported on the side plate portion 34 of the base 32 so as to be pivotable in the vertical direction between a locking angle rotated downward by a support shaft 45 and an unlocking angle rotated upward. And is biased toward the upper unlocking angle direction by a spring 46 stretched between the side plate portion 34 side. The rotation of the lock member 44 in the unlocking angle direction is restricted by a slide plate 61 described later.

  On the front end side of the lock member 44, a groove portion 48 is formed that is detachably engaged with the hook 26 of the closed door 24. As shown in FIG. 1 (a), when the door 24 is opened and the locking member 44 is at the upper unlocking angle, the rear edge of the groove 48 projects obliquely into the openings 35 and 36. As well as being disposed, the front edge of the groove 48 is disposed above the openings 35 and 36 and is in an unlocked state. On the other hand, when the door 24 is closed and the hook 26 of the door 24 is inserted into the openings 35 and 36, the hook 26 engages and presses the rear edge of the groove 48, so that the lock member 44 is moved downward. Rotates to the locking angle. As shown in FIG. 1 (b) or 1 (c), when the lock member 44 is rotated to the downward locking angle, the front edge of the groove 48 is positioned on the front side of the hook 26, and the lock member 44 Locked to lock 26. Therefore, the shape of the groove 48 of the lock member 44 is such that the hook 26 when the door 24 of the storage chamber 16 is closed and the lock member 44 rotates in the downward locking direction to open the door 24 of the storage chamber 16. Thus, the lock member 44 is formed to rotate in the upward unlocking direction. When the lock member 44 is in the locked state in which the hook 26 is locked, a biasing force that biases the lock member 44 to the upper unlocking angle is used to bias the door 24 in the closing direction by a spring incorporated in the hinge 25. The force is greater and the locked state in which the hook 26 is locked by the lock member 44 is maintained.

  A contact piece 49 is bent at the upper part in the vicinity of the front end side of the lock member 44.

  As shown in FIG. 3, the locking unit 27 includes door opening / closing detection means 53 that detects opening / closing of the door 24. This door open / close detection means 53 has an open / close detection lever 54 arranged in parallel with the lock member 44, and the open / close detection lever 54 is attached to the side plate portion 34 of the base 32 so as not to interfere with the lock member 44. The plate 55 is supported so as to be slidable in the front-rear direction, and is urged forward by a spring 56 stretched between the plate 55 and the mounting plate 55.

  The front end portion of the opening / closing detection lever 54 is disposed facing the openings 35 and 36 together with the front end portion of the lock member 44, and is pushed by the hook 26 inserted from the openings 35 and 36 to slide backward. When the open / close detection lever 54 slides backward, the detection piece of the micro switch 57 is pushed. The opening / closing of the door 24 is detected by turning the micro switch 57 on and off.

  By providing the door opening / closing detection means 53 independently of the lock member 44, it is possible to detect an abnormal state such as the lock member 44 being rotated to the locking angle with the door 24 opened.

  As shown in FIGS. 1 and 3 to 5, a slide plate 61 is attached to the side plate portion 34 of the base 32 so as to be slidable in the vertical direction while being always placed on the upper portion of the lock member 44. ing. Two long holes 63 that are long in the vertical direction are formed in parallel in the base plate portion 62 of the slide plate 61, and each of the long holes 63 is engaged with two pins 64 protruding from the side plate portion 34 of the base 32. The slide plate 61 is attached to the side plate portion 34 of the base 32 so as to be slidable in the vertical direction. The slide plate 61 has a position slid downward as a locking position and a position slid upward as an unlocking position.

  A bent piece 65 that contacts the upper surface of the contact piece 49 of the lock member 44 is bent at the rear side of the slide plate 61, and an upright piece 66 is bent at the lower front side of the slide plate 61. .

  A restricting portion 67 is formed to protrude from the rear side of the upper side of the slide plate 61, and an unlocking permission portion 68 located below the restricting portion 67 is formed at the front side of the upper side.

  A guide piece 69 for assisting the sliding of the slide plate 61 in the vertical direction is disposed on the side of the slide plate 61.

  As shown in FIGS. 1 to 4 and 6, the side plate portion 34 of the base 32 has a solenoid 72 as a driving means at a position above the slide plate 61, with the plunger 73 moving in the front-rear direction. It is fixed. This solenoid 72 is displaced by the input of the drive pulse to either the locked position where the plunger 73 protrudes backward and the unlocked position where the plunger 73 protrudes forward, and the permanent magnet is not energized. It is a bistable self-holding type latching solenoid that holds either state.

  The solenoid 72 is provided with a stopper body 74 that moves in the front-rear direction in conjunction with the advance and retreat of the plunger 73 of the solenoid 72. The stopper body 74 includes a main driving member 75 directly connected to the plunger 73 and a driven member 76 that follows the operation of the main driving member 75.

  The main moving member 75 is formed with a flat plate-like substrate portion 77 disposed on the lower side of the solenoid 72, and a fixed piece 78 that is bent upward from the rear end of the substrate portion 77 and disposed on the rear side of the solenoid 72. A coupling hole 79 coupled to the rear end of the plunger 73 is formed in the center of the fixed piece 78. Two long holes 80 that are long in the front-rear direction are formed in the base plate portion 77 in parallel, and the screw 82 is fixed to the frame of the solenoid 72 through a slide member 81 that is slidably engaged with each of the long holes 80, whereby the main drive member 75 is attached to the solenoid 72 so as to be slidable in the front-rear direction. Further, the one side edge of the substrate portion 77 is stretched between the driven member 76 that contacts the driven member 76 and forcibly pushes the driven member 76 rearward, and the driven member 76. A flange 85 is formed to hook one end of a spring 84 as an urging means.

  The driven member 76 is formed with a substrate portion 86 disposed on the side of the solenoid 72 and an operating piece 87 that is bent from the front end of the substrate portion 86 and disposed on the front side of the solenoid 72. The board portion 86 is formed with two long holes 88 that are long in the front-rear direction, and the screw 90 is fixed to the frame of the solenoid 72 through a slide member 89 that is slidably engaged with each of the long holes 88. The solenoid 72 is attached to be slidable in the front-rear direction. A protruding portion 91 that contacts the pushing piece 83 of the main driving member 75 is formed on the rear side of the lower side of the substrate portion 86, and the protruding portion 91 has a hole portion 92 that hooks the other end of the spring 84.

  On the lower side of the operating piece 87 of the driven member 76, a locking piece 93 is formed that is bent forward and the left end protrudes above the slide plate 61. The locking piece 93 is located in the upper region of the restricting portion 67 on the rear side of the upper side of the slide plate 61 at the position where the driven member 76 moves rearward, and moves upward of the slide plate 61 by contact with the restricting portion 67. The locking member 44 is held at the locking angle, while the driven member 76 is positioned in the upper region of the unlocking allowable portion 68 on the front side of the upper side of the sliding plate 61 at the position where the driven member 76 has moved forward. The lock member 44 is allowed to move upward to the unlocking angle while allowing upward movement.

  When the locking signal is sent from the control means 23 to the solenoid 72, the plunger 73 protrudes rearward, the main driving member 75 also moves rearward integrally, and the driven member via the pushing piece 83 of the main driving member 75. 76 also moves backward. The positions at which the main driving member 75 and the driven member 76 are moved rearward are such that the locking piece 93 of the driven member 76 is positioned above the restriction portion 67 of the slide plate 61 and restricts the upward movement of the slide plate 61. Thus, the locking member 44 is in the locking position for holding the locking angle. On the other hand, when the unlock signal is sent from the control means 23 to the solenoid 72, the plunger 73 is moved forward and the main driving member 75 is also moved forward together. At this time, the driven member 76 is the plunger 73 or the main driving member. It is not pushed directly by 75 but moves forward by the urging force of the spring 84 spanned between the main driving member 75 and the driven member 76. The positions where the main driving member 75 and the driven member 76 are moved forward are such that the locking piece 93 of the driven member 76 is positioned above the unlocking permission portion 68 of the slide plate 61 and the slide plate 61 is moved upward. The unlocking position is allowed. Further, the main driving member 75 and the driven member 76 are held in the locked position or the unlocked position by the solenoid 72 in a non-energized state.

  An inclined piece 94 inclined slightly rearward is formed on the upper portion of the operating piece 87. When the solenoid 72 is in the locked state, by operating the cylinder lock 40, the unlocking plate 95 slidably attached to the side plate portion 34 of the base 32 is raised and protrudes from the unlocking plate 95. The inclined piece 94 is pushed forward by the pin 96 (see FIG. 1 (a)), the main driving member 75 is moved to the front unlocking position through the driven member 76 and the pushing piece 83, and the solenoid 72 is moved. Switch to the unlocked position and perform the manual unlocking function to release the locked state.

  The positions of the main driving member 75 and the driven member 76 are detected by the micro switches 97 and 98, respectively. The operation state of the solenoid 72 is detected by turning on / off the micro switch 97, and whether the driven member 76 is in the locked position or the unlocked position is detected by turning on / off the micro switch 98.

  Therefore, the locking member 99 that is in the locked state in which the lock member 44 locks the hook 26 of the door 24 by the drive of the solenoid 72 is configured by the lock member 44, the slide plate 61, the main driving member 75 and the driven member 76 of the stopper body 74, and the like. Has been.

  As shown in FIGS. 1, 3, and 5, a lever bracket 102 that is coupled to the shaft portion 37 a of the locking lever 37 and slides in the vertical direction is disposed on the front plate portion 33 of the base 32.

  The lever bracket 102 includes a base portion 104 having leg portions 103 and a locking portion 105 in which a side piece of the base portion 104 is bent vertically so as to be parallel to the side plate portion 34 of the base 32. In the center of the base portion 104, a connecting hole 106 to which the shaft portion 37a of the locking lever 37 is connected and a plurality of long holes 107 that are long in the vertical direction are formed. The lever bracket 102 is attached so as to be slidable in the vertical direction by stopping screws 109 engaged with the respective long holes 107 at the front plate portion 33 of the base 32.

  The lever bracket 102 moves up and down integrally with the locking lever 37, that is, moves between an upper unlocking position and a lower locking position. The lever bracket 102 is stretched between the front plate portion 33 of the base 32 and a spring 110 that biases upward so that the locking lever 37 and the lever bracket 102 always maintain the unlocked position.

  When the locking lever 37 is lowered to the locking position, the leg portion 103 of the lowered lever bracket 102 that is integrally locked presses the detection piece of the micro switch 111. Whether the locking lever 37 is in the unlocked position or operated in the locked position is detected by turning the microswitch 111 on and off.

  A bent piece 112 is formed in the vicinity of the base of the leg portion 103 of the base portion 104 so as to abut on the upright piece 66 of the slide plate 61. When the locking lever 37 is lowered to the locking position, the bent piece 112 pushes down the slide plate 61 to lower the lock member 44 to the lower limit position of the locking angle, and the hook 26 and the groove portion 48 of the lock member 44 are engaged. Is more certain.

  The locking portion 105 is formed with an opening 113 into which the locking piece 93 of the driven member 76 is inserted and arranged, and a slit-like engagement that allows the locking piece 93 to engage with the upper and lower portions of the rear edge of the opening 113. Stop grooves 114 and 115 are formed. When the driven member 76 moves to the rearward locked position with the locking lever 37 in the upper unlocked position, the locking piece 93 of the driven member 76 engages with the lower locking groove 115, and the locking lever When the follower member 76 moves to the rearward locking position while 37 is in the lower locking position, it engages with the upper locking groove 114. As a result, in the locked state, the locking lever 37 cannot be operated regardless of the position.

  Therefore, when the locking lever 37 is in the locked position or unlocked position by the driven member 76 having the locking piece 93, the lever bracket 102 having the locking grooves 114, 115, etc., and the locking means 99 is in the locked state, A holding means 116 that restricts the movement of the locking lever 37 in the vertical direction is configured. Further, the slide plate 61, the lever bracket 102, and the like can be moved between the lock member 44 and the driven member 76 in a direction crossing the moving direction of the driven member 76 in conjunction with the rotation of the lock member 44. An interlocking body 117 that is disposed and contacts the driven member 76 at the locking position to hold the lock member 44 at the locking angle is configured.

  FIG. 7 shows a block diagram of the control means 23 of the electric lock device 28. The control means 23 inputs detection signals from the microswitches 57, 97, 98 and 111 and controls the driving of the solenoid 72.

  The control means 23 controls the position of the locking lever 37 in the function of the first mode which is a normal use mode in which the locking mechanism 99 is locked by driving the solenoid 72 on the condition that the locking lever 37 is in the locking position. Regardless of this, it has the function of the second mode for simultaneous locking, in which the solenoid 72 is driven to lock the locking means 99.

  Next, the operation of the present embodiment will be described.

  First, an outline of the use of the locker device 11 will be described with reference to FIGS.

  In the luggage depositing operation, the user opens the door 24 of the storage room 16, puts the luggage into the storage room 16, closes the door 24, and lowers the locking lever 37 to the locking position. Thereby, the control means 23 transmits a locking signal to the corresponding locking unit 27 and temporarily locks the locking unit 27.

  The user performs predetermined procedures such as payment of a fee and acquisition of a personal identification number at the central control unit 15. When the procedure is normally completed, the locking unit 27 maintains the locked state and is locked. On the other hand, when the procedure is not completed, the temporary locking of the locking unit 27 is released, and the process returns to a standby state in which the door 24 can be opened.

  Further, in the baggage taking-out operation, the user performs predetermined procedures such as input of a password and payment of an additional fee at the central control unit 15.

  When the procedure is normally completed, the control means 23 transmits an unlocking signal to the corresponding locking unit 27 and unlocks the locking unit 27. When the locking unit 27 is unlocked, the locking lever 37 returns to the upper unlocking position.

  The user opens the door 24, takes out the luggage from the storage room 16, and closes the door 24.

  The simultaneous locking will be described.

  The administrator of the locker device 11 performs simultaneous locking setting in the central control unit 15.

  The control means 23 searches the storage chambers 16 in the unlocked state (empty state), transmits a lock signal to the lock units 27, and locks the lock units 27.

  The storage chamber 16 being used and locked is left as it is, and the locking unit 27 is locked after the luggage is taken out.

  Next, the operation of the locking unit 27 will be described.

  FIG. 1A shows a state where the locking unit 27 is unlocked and the door 24 is opened.

  The solenoid 72 is in an unlocked state in which the plunger 73 has moved forward, the main driving member 75 and the driven member 76 of the stopper body 74 are positioned at the front unlocking position, and the locking piece 93 of the driven member 76 is attached to the slide plate 61. It is located above the unlocking permission portion 68. The lock member 44 is rotated to the upper unlocking angle by the bias of the spring 46, and the unlocking permitting portion 68 faces the locking piece 93 of the driven member 76 and the slide plate 61 is allowed to move upward. Located in the upper unlocking position. The locking lever 37 and the lever bracket 102 are located at the upper unlocked position by the bias of the spring 110.

  When the door 24 is closed, the hook 26 of the door 24 is engaged with the groove portion 48 of the lock member 44, and the lock member 44 is rotated to the lower locking angle against the bias of the spring 46 by the pressure by the hook 26. At the same time, the slide plate 61 moves to the lower locking position in conjunction with the lock member 44. If the door 24 is opened from this state, the hook 26 moves forward, whereby the lock member 44 rotates to the upper unlocking angle, and the slide plate 61 also moves to the upper unlocking position.

  Next, a first mode that is a normal use mode of the locker device 11 will be described with reference to FIG.

  When the user puts the luggage into the storage chamber 16 and closes the door 24, the hook 26 of the door 24 engages with the groove portion 48 of the lock member 44, and the lock member 44 resists the bias of the spring 46 by pressing by the hook 26. As a result, the slide plate 61 is moved to the lower locking position in conjunction with the locking member 44. The open / close detection lever 54 is pushed backward by the hook 26 of the door 24, the micro switch 57 is turned on, and it is detected that the door 24 is in the closed state.

  Further, when the user pulls down the locking lever 37 to the lower locking position, the lever bracket 102 moves down to the lower locking position integrally with the locking lever 37 against the bias of the spring 110, and the lever bracket 102 The switch 111 is turned on to detect that the locking lever 37 has moved to the locking position. At this time, the bent piece 112 of the lever bracket 102 contacts the upright piece 66 of the slide plate 61 and pushes it downward further, and the lock member 44 is lowered to the lower limit position below the lock position via the slide plate 61. Further, the engagement between the hook 26 and the groove 48 of the lock member 44 is made more reliable.

  By detecting that the door 24 is closed by the micro switch 57 and detecting that the locking lever 37 has moved to the locking position by the micro switch 111, the control means 23 drives the solenoid 72, and the locking unit 27 Is temporarily locked. That is, when the solenoid 72 is driven to move the plunger 73 to the rearward locking position, the main driving member 75 and the driven member 76 of the stopper body 74 integrally move to the rearward locking position, and the locking piece of the driven member 76 The locking member 44 that engages the hook 26 by restricting the slide plate 61 from moving up to the upper unlocking position by moving the 93 above the regulating portion 67 of the slide plate 61 moving to the lower locking position. Is temporarily locked in the locked state.

  At the same time, the locking piece 93 of the driven member 76 also engages with the locking groove 114 on the upper side of the lever bracket 102 that has moved to the lower locking position, and the lever bracket 102 is unlocked upward by the bias of the spring 110. The movement to the position is restricted, and the locking lever 37 is held in the locking position. By holding the locking lever 37 in the locking position, it can be confirmed at a glance that the storage chamber 16 is in use.

  Further, when the user normally completes the predetermined deposit procedure at the central control unit 15, the locking unit 27 maintains the locked state and becomes the actual locking. Note that the temporary locking state and the actual locking state are mechanically the same state.

  In this way, when locking in the first mode, since the operation to the locking position of the locking lever 37 is a locking condition, the user can be surely checked for locking, which is not intended by the user. Locking can be prevented, and at this time, since the holding means 116 for holding the locking lever 37 in the locking position is provided, the locking state can be easily confirmed by the position of the locking lever 37.

  Further, at the time of locking in the first mode, the bent piece 112 of the lever bracket 102 abuts against the standing piece 66 of the slide plate 61 and pushes down further downward, and the lock member 44 is locked via the slide plate 61. Therefore, the hook 26 and the groove portion 48 of the lock member 44 can be more reliably engaged with each other.

  Furthermore, the single solenoid 72 can realize both functions of holding the lock member 44 in the locked state and holding the lock lever 37 in the locked position. Therefore, the electric lock device 28 can be configured simply.

  In addition, when a predetermined removal procedure by the user is normally completed during the package removal operation, the control means 23 drives the solenoid 72 and unlocks the locking unit 27. That is, when the solenoid 72 is driven to move the plunger 73 into the forward unlocking position, the main driving member 75 and the driven member 76 of the stopper body 74 are moved to the front unlocking position, and the locking piece of the driven member 76 is moved. 93 moves above the unlocking permission portion 68 of the slide plate 61, allows the slide plate 61 to rise to the upper unlocking position, and unlocks the locking unit 27.

  At the same time, the locking piece 93 of the driven member 76 is disengaged from the upper locking groove 114 of the lever bracket 102, and the lever bracket 102 and the locking lever 37 are moved to the upper unlocking position by the bias of the spring 110 and unlocked. Can be confirmed.

  Therefore, the door 24 unlocked by the locking unit 27 can be opened.If the door 24 is moved in the opening direction, the hook 26 moves forward so that the lock member 44 is moved to the upper unlocking angle. While rotating, the slide plate 61 is also moved to the upper unlocking position, and the door 24 can be opened.

  Next, a second mode that is a simultaneous locking mode of the locker device 11 will be described with reference to FIG.

  In the operation of the locker device 11, for example, it may be necessary to prohibit the deposit of luggage for a while due to the need for a special alert. In such a case, the administrator of the locker device 11 operates the central control unit 15 and performs an operation of simultaneously locking the locking units 27 in the empty storage chamber 16.

  In the second mode, which is a simultaneous locking mode of the locker device 11, when the door 24 is detected to be closed by the detection of the micro switch 57, the control means 23, regardless of the position of the locking lever 37, The solenoid 72 is driven and the locking unit 27 is locked. That is, when the solenoid 72 is driven to move the plunger 73 to the rearward locking position, the main driving member 75 and the driven member 76 of the stopper body 74 integrally move to the rearward locking position, and the locking piece of the driven member 76 The lock member 44 that engages with the hook 26 by restricting the slide plate 61 from moving upward to the unlocking position of the slide plate 61 is moved above the restricting portion 67 of the slide plate 61 that has moved downward to the locking position. Is locked in the locked state. However, the locking unit 27 in the storage chamber 16 in use is excluded because it is already locked.

  At this time, since the locking lever 37 is normally in the upper unlocking position, the locking piece 93 of the driven member 76 is engaged with the locking groove 115 on the lower side of the lever bracket 102 and locked via the lever bracket 102. The lever 37 is held in the unlocked position. As a result, it is possible to prevent the locking lever 37 of the locking unit 27 that is locked all at once from being tampered with.

  For the storage chamber 16 in use, the locking unit 27 is locked in the same manner as described above after the locking unit 27 is unlocked by the user's operation, the package is taken out, and the door 24 is closed.

  Thus, when locking in the second mode, automatic locking can be performed regardless of whether or not the locking lever 37 is operated.

  Further, even when the locking lever 37 is in the unlocked position, the movement of the locking lever 37 is restricted and held in the unlocked position, so that unnecessary operation of the locking lever 37 can be prevented, and failure and malfunction can be prevented. .

  Further, when the administrator of the locker device 11 operates the central control unit 15 and performs an operation of releasing the simultaneous locking, the control means 23 drives the solenoid 72 and unlocks the locking unit 27. That is, when the solenoid 72 is driven to move the plunger 73 into the forward unlocking position, the main driving member 75 and the driven member 76 of the stopper body 74 are moved to the front unlocking position, and the locking piece of the driven member 76 is moved. 93 moves above the unlocking permission portion 68 of the slide plate 61, allows the slide plate 61 to rise to the upper unlocking position, and unlocks the locking unit 27.

  At the same time, the locking piece 93 of the driven member 76 is disengaged from the locking groove 115 on the lower side of the lever bracket 102 to allow the lever bracket 102 and the locking lever 37 to move.

  Therefore, the door 24 unlocked by the locking unit 27 can be opened.If the door 24 is moved in the opening direction, the hook 26 moves forward so that the lock member 44 is moved to the upper unlocking angle. While rotating, the slide plate 61 is also moved to the upper unlocking position, and the door 24 can be opened.

  Next, countermeasures for unlocking problems due to overloading of luggage will be described.

  In FIG. 1 (b), when a large-capacity load is pushed into the storage chamber 16 of the locker device 11 and this load is pushed back to the door 24 side, or a large load stored in the storage chamber 16 is transferred to the door 24. When the door falls down and presses the door 24 in the opening direction, a force acts in a direction in which the hook 26 of the door 24 pulls the lock member 44 forward. The groove portion 48 of the lock member 44 is formed in a shape in which the lock member 44 is rotated in the upward unlocking direction by the hook 26 when the door 24 of the storage chamber 16 is opened. When pulled forward, the lock member 44 attempts to rotate toward the upper unlocking position. Along with this, the slide plate 61 and the lever bracket 102 also move upward, and the lower edge portion of the restricting portion 67 of the slide plate 61 and the locking groove 114 of the lever bracket 102 intersects with the locking piece 93 of the driven member 76. The locking piece 93 of the driven member 76 may not be detached from the slide plate 61 or the lever bracket 102 when unlocked due to the frictional force of the contact.

  Since the main driving member 75 and the driven member 76 of the stopper body 74 are independent members, even when the lock member 44 is pulled forward by the hook 26 at the time of unlocking, the control means When the solenoid 72 is driven at 23 to move the plunger 73 into the forward unlocking position, the main moving member 75 of the stopper body 74 moves to the front unlocking position together with the plunger 73. At this time, the locking piece 93 of the driven member 76 does not come off the slide plate 61 or the lever bracket 102 during unlocking, and the driven member 76 is stretched between the main driving member 75 even if it does not move to the unlocked position. The spring 84 is biased in the unlocking direction ahead.

  Therefore, for example, if the state in which the lock member 44 is pulled forward by the hook 26 is released even if the door 24 of the storage chamber 16 is pushed in the closing direction, the driven member 76 is immediately moved forward by the bias of the spring 84. It can be moved to the unlocking position and unlocked.

  Thus, since the direction in which the lock member 44 moves from the locking angle toward the unlocking angle and the direction in which the main driving member 75 and the driven member 76 move by the solenoid 72 are in a positional relationship, the locking member 44 in the locked state On the other hand, the driven member 76 may not move to the release position when an excessive force is applied in the unlocking direction, but even in such a case, the solenoid 72 is driven to move the main driving member 75 to the unlocked position. Further, the driven member 76 is biased in the unlocking position direction by the spring 84 connected to the main driving member 75 that moves to the unlocking position, and the locking member 44 cannot be forced in the unlocking direction. When the force is released, the follower member 76 is moved to the unlocked position by the bias of the spring 84, and the rotation of the lock member 44 to the unlock angle can be permitted. Unreasonable force applied in the unlocking direction is not easily transmitted to the solenoid 72 In addition, the solenoid 72 can always operate normally and can be unlocked reliably.

  As the spring 84, a tension spring is illustrated as shown in FIGS. 1 to 3 and FIG. 5, but a compression spring may be used.

  In the first mode, the locking member 44 is lowered to the lower limit position of the locking position by the bent piece 112 of the lever bracket 102, and the engagement between the hook 26 and the groove portion 48 of the locking member 44 is further ensured. However, even when the bent piece 112 is not formed on the lever bracket 102, the driven member 76 regulates the rise of the slide plate 61, so that the locked state can be sufficiently maintained.

  Further, the locking operation means is not limited to the locking lever 37, and may be, for example, a rotary knob.

  Further, the electric lock device 28 is not limited to the locker device 11, and can be applied to, for example, furniture or a door of a house.
