Description

  The present invention relates to a locking device that can be locked by interlocking locking mechanisms provided in a plurality of storages constituting a storage system.

  Conventionally, as a locking device that can lock a plurality of storages in conjunction with each other, for example, a cylinder lock is provided only in a specific storage among a plurality of storages arranged in series with each other. Only one cylinder lock is operated by providing a mechanical interlocking mechanism that can mechanically transmit the operation force when manually locking and unlocking the lock to the lock mechanism of each storage other than the specific storage. Therefore, a lock device that can lock and unlock the lock mechanisms of all storages constituting the storage system, in other words, a lock device that can mechanically interlock the lock mechanisms of all storages constituting the storage system is proposed. (For example, refer to Patent Document 1).

On the other hand, in Patent Document 2, for each lock mechanism included in a plurality of storages constituting the storage system, a locking / unlocking device capable of electrically locking / unlocking the lock mechanism is installed, and what is the locking / unlocking device? A lock device provided with a control device provided separately is disclosed. The lock device will be described in detail. Each lock / unlock device provided in the lock mechanism of the plurality of storage units and the control device are electrically connected by electrical wiring, so that the control device can be installed from any one place. By operating each locking / unlocking device of a plurality of storage boxes by electrical remote control, the locking mechanism provided with each locking / unlocking device can be locked and unlocked all at once.
Japanese Patent Publication No.7-113298 Japanese Patent No. 2906283

  However, the locking device as disclosed in Patent Document 1 tries to lock / unlock the locking mechanism arranged in a large number of storages based on the operation force when the user manually locks / unlocks the cylinder lock. To do. In other words, considering the normal locking / unlocking operation performed manually by the user, it takes an excessive burden on the user's fingers to lock and unlock many locking mechanisms at once with the operating force of the fingertip. The number of lock mechanisms that can be locked at a time is limited by the operating force of the fingers of the fingers, and in reality, the storage lock mechanism that is arranged at a position far away from the storage with the locking portion is operated. It is difficult. For this reason, the number of storages that can be connected in series is practically limited to a small number.

  On the other hand, the locking device as disclosed in Patent Document 2 connects each locking / unlocking device and a control device separate from the locking / unlocking device by electric wiring, so that each locking / unlocking by the control device is performed. Although the remote operation of the locking device can be easily performed and there is a degree of freedom in the location of the locking and unlocking device and the layout of the electrical wiring, it has the advantage that it can easily lock and unlock a large number of storage boxes at once, When each locker is provided with a locking / unlocking device and each locking / unlocking device is connected by electric wiring, it is necessary to provide a lock mechanism for generating an electric driving force in each of the storages. And the control device must be connected by electrical wiring, resulting in increased costs during manufacturing and introduction, and complicated installation work and maintenance work. In addition, since the locking / unlocking devices installed in each storage are electrically connected to each other, if a contact failure or failure occurs in one location of each locking device, the entire locking device may become inoperable. In addition, it takes a lot of time and labor to find and repair the defective part and the troubled part.

  The present invention pays attention to such inconveniences, and can perform locking and unlocking with respect to the respective storages of the storage system all at once, and can also realize cost reduction and reduction of installation and maintenance labor. Is to provide.

  In order to achieve such an object, the present invention takes the following measures. That is, the lock device of the storage system according to the present invention includes a storage body having a storage space, an open position where the storage space communicates with the outside, and a closed position where the storage space can be isolated from the outside. And a lock device applied to a storage system in which a plurality of storages each having at least an opening / closing body set so as to be movable relative to the storage body is provided, And a lock mechanism that can take a lock position that prohibits the movement of the opening / closing body in the closed position to the open position or a lock release position that releases the prohibition, and the lock mechanism A single device that electrically receives a drive signal for changing from one of the position and the unlocked position to the other position and generates a driving force based on the received drive signal. The drive force generator and the lock mechanisms are mechanically transmitted to the lock mechanisms of the plurality of storages arranged in a plurality of continuous arrangements, thereby interlocking the lock mechanisms. And a transmission mechanism capable of simultaneously changing from either one of the locked position or the unlocked position to the other position.

  Here, the storage to which the present invention is applied has a drawer as an opening / closing body, such as a door body such as an open door (including a double door) or a sliding door, or a locker equipped with a drawer, etc. as an opening / closing body. The thing of the various aspects which have internal space for accommodating articles | goods, such as a wagon, is contained. Further, the drive signal that is electrically received by the drive force generation unit includes not only a mode of receiving via, for example, an electric wiring but also a mode of receiving by wireless communication. That is, it is possible to adopt a configuration that is not limited to the position where the drive signal is generated. Furthermore, the mode in which the transmission mechanism is arranged is not limited to a mode in which the transmission mechanism is linearly arranged in any direction, and includes a mode in which the transmission mechanism is bent or curved at a predetermined location, for example. And the connection direction of each storage which comprises a storage system does not ask | require upper / lower or right / left distinction.

  If it is such, since a plurality of storages can be locked and unlocked at a time by the driving force generated by the driving force generator transmitted via the transmission mechanism, it is necessary to individually lock and unlock the plurality of storages. There is no. Further, since the power is mechanically propagated to at least the transmission mechanism and the lock mechanism based on the drive force generated electrically in the drive force generation unit, all the storages are simultaneously unlocked and unlocked mechanically. As long as the driving force generated in the driving force generating unit can withstand as compared with a conventional locking device of the type, simultaneous locking and unlocking can be realized even if more storages are added. Furthermore, unlike the case where all the storages are electrically locked and unlocked, only one part around the driving force generating unit requires an electrical configuration, so that all storages can be unlocked simultaneously. Compared with a conventional locking device that locks electrically, the electrical wiring can be drastically reduced, the number of potential breaks such as disconnection is reduced, and a fault occurs in the electrical system. However, it is possible to easily identify the failure location. Of course, unlike the same document, since the electrical wiring is reduced and a conventional electrical locking / unlocking device is not prepared for each storage, the introduction cost can be lowered as a result.

  Further, in order to realize the opening / closing operation of the opening / closing body and the mechanism of locking or unlocking with a simple configuration using a common member, the locking mechanism is provided in the opening / closing body of each storage case at the closed position. An operating body for operating an opening / closing operation of the opening / closing body, and a lock body for fixing the operating body to be inoperable at the locking position or to be operably fixed at the unlocking position with the opening / closing body in the closed position. It is desirable to provide That is, with such a configuration, the operating body can be used as a member to be locked or unlocked by the locking body while being used as a member for performing an opening / closing operation on the opening / closing body.

  In order to change the lock mechanism from either the locked position or the unlocked position to the other position with a very simple operation using a simple structure, the driving force generating unit is moved to the driving position. The transmission mechanism is assumed to have a rotating shaft that rotates by force, and has a substantially rod-shaped transmission shaft member in which the transmission mechanism is connected to a portion whose one end is displaced from the axial center of the rotating shaft. It is desirable that the rotation mechanism of the rotation shaft is converted into the movement of the transmission shaft member, and the lock mechanism is configured to be interlocked with the movement of the transmission shaft member.

  Further, the lock mechanism is provided with an operating body provided on the opening / closing body of the storage for operating the opening / closing operation of the opening / closing body, and the operating body cannot be operated at the locking position when the opening / closing body is in the closed position. When a locking body that is fixed or operably unlocked at the unlocking position is provided, the transmission mechanism is provided between the forward / backward movement of the transmission shaft member and the locking position and unlocking position of the locking body. It is also possible to provide an interlocking member that interlocks the operations in the above. In this case, at least the configuration of the storage can be shared, which contributes to cost reduction.

  The transmission mechanism is provided with a substantially rod-shaped transmission shaft member, and when the transmission shaft member is extended in the lateral direction, for example, the storage case is arranged in two rows in the vertical direction, and is orthogonal to the direction in which the transmission shaft member extends. In order to continuously arrange the storages in the direction in which the pair of storages are arranged, at least a part of the storage system is provided with a pair of storages arranged in series, and the transmission is performed between the opening / closing bodies of the pair of storages. A shaft member is disposed, and the lock mechanism is disposed at a position interposed between the opening / closing body and the transmission shaft member, and the transmission shaft member transmits the driving force generated from the driving force generator to the pair of storages. It is desirable that each of the lock mechanisms is mechanically transmitted.

  Further, in the case where the transmission shaft member is arranged along the direction in which a plurality of storages are arranged in series, in order to efficiently transmit the advance / retreat operation of the transmission shaft member to the lock mechanism corresponding to each storage, The locking mechanism is disposed at a predetermined position interposed between the transmission shaft member and the transmission shaft member, and the transmission shaft member is configured to mechanically transmit the driving force generated from the driving force generator to the locking mechanism, respectively. It is preferable to do.

  In order to easily determine whether the lock mechanism is in the locked position or the unlocked position with a glance at the storage, the lock on the opening / closing body of each storage or the opening / closing body of the storage It is desirable to provide a display that indicates that the mechanism is in the locked or unlocked position. Further, as an aspect having a simple configuration, the display unit is formed in a display window formed by opening the opening / closing body, and a portion that is visible through the display window at the lock position and the unlock position in the lock body. It can be said that it is composed of a notation indicating the locked state or unlocked state.

  According to the lock device of the storage system according to the present invention, the lock for prohibiting the movement of the opening / closing body at the closed position in the storage by the driving force generated by the driving force generation unit via the transmission mechanism is provided. Since the plurality of storages can be locked / unlocked at a time by transmitting to a plurality of lock mechanisms that can take the position or the unlocked position where the prohibition is released, there is no need to individually lock / unlock the plurality of storages. Further, since the power is mechanically propagated to at least the transmission mechanism and the lock mechanism based on the drive force generated electrically in the drive force generation unit, all the storages are simultaneously unlocked and unlocked mechanically. As long as the driving force generated in the driving force generating unit can withstand as compared with a conventional locking device of the type, simultaneous locking and unlocking can be realized even if more storages are added. Furthermore, unlike the locking device in a mode that electrically locks and unlocks all the storages, it is necessary to have an electrical configuration only at one location around the driving force generating unit, so that it is more than the conventional one. Electrical wiring can be drastically reduced, reducing the number of locations where failures such as disconnection may occur, facilitating identification of failure locations, and reducing costs, labor, and time for manufacturing, installation, and maintenance It is possible to realize.

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

  FIG. 1 schematically shows a storage system SA to which a locking device LA according to a first embodiment of the present invention is applied. In the figure, the lock device LA is a portion schematically indicated by a one-dot chain line.

  First, the configuration of the storage system SA will be briefly described. In this storage system SA, a plurality of storages S (in the illustrated example, only four units are shown for simplification of explanation, but it goes without saying that it may be more than that) are arranged vertically and horizontally. A driving force generator PG and a transmission mechanism D, which will be described later, are connected between two storages S arranged on the upper side and two storages arranged on the lower side. The middle frame S3 to be housed is interposed.

That is, as shown in FIGS. 1, 2 and 3, the latch structure R has a pair of upper and lower horizontally movable latch claws Ra on one door body S2 (right side in the front view in the illustrated example), and these latches. A synchronization axis Rb for synchronizing the claw Ra, an operating body 31 provided with a handle 31a for horizontally rotating the synchronization axis Rb and opening / closing the door body S2 itself, are provided so as to be detachable from the latch claw Rb. The mating latch hole Rd is formed vertically on the front side of the storage body S1, and the opening / closing end side edge of the other door body S2 (left side in the illustrated example) is provided with the latch claw Ra. Only the one door body S2 is directly engaged with and disengaged from the storage body S1 by overlapping in the front-rear direction inside the opening / closing end side edge of the door body S2. That is, the operating body 31 is provided with a slider 31b that is interposed between the handle 31a and the synchronization axis Rb and slides in the width direction of the door body S2. The door body S2 is connected to the storage body S1. In the closed closed position, when the handle 31a is pulled and rotated, the slider 31b is twisted so as to horizontally rotate the synchronization shaft Rb, so that the latch claw Ra is detached from the state engaged with the latch hole Rd. It will be. The synchronous shaft Rb is biased by the coil spring Rc in a direction to engage with the latch hole Rd. Hereinafter, when referring to the door body S2, the door body S2 including mechanism parts such as the latch claws Ra is indicated unless otherwise noted.

  The lock device LA according to the present embodiment can be operated in a locked state in which the operating body 31 is locked to be inoperable in a state where the door body S2 is positioned at the closed position, that is, in a state where it is closed with respect to the storage body S1. By switching between the unlocked state, all the storages S are provided for simultaneous locking and unlocking. As a configuration for this, the lock device LA includes a lock mechanism L that locks and unlocks the door body S2 of the storage S, a drive force generator PG that generates a drive force for operating the lock mechanism, and a drive force generator. A transmission mechanism D that mechanically transmits a driving force from the PG to the lock mechanism L is provided.

  First, the driving force generation unit PG is mainly provided in the middle frame S3 in the present embodiment, and has a control unit CU that controls the locking and unlocking of the door body S2, as will be described later. In this embodiment, the control unit CU adopts a mode of controlling ON / OFF of the operation of the motor 11 described later by a remote control method. Specifically, the control unit CU receives the remote control unit CUa for operating the driving force generation unit PG from a position away from the storage system SA, the reception unit CUb for receiving a signal from the remote control unit CUa, and the reception unit CUb. The electric wiring CUc for relaying the received signal to the motor 11 is mainly used. Here, for transmission and reception of signals between the remote control device CUa and the receiving device CUb, for example, an appropriate wireless method such as infrared rays can be adopted, and the receiving device CUb can be arranged at an appropriate location of the storage system SA. it can. In the present embodiment, the receiving device CUb is provided at the upper front corner (for example, the heel portion) of the storage S arranged at the upper right as a location where the signal from the remote control device CUa can be easily received and the electric wiring CUc to the motor 11 can be shortened. Is arranged. Since the receiving device CUb, the driving force generator PG, and the like operate by receiving power supply, the lock device LA has an electric wiring for receiving power supply from an external power source or an internal power supply device. I have.

  As shown in FIGS. 4 and 5, the driving force generator PG further includes an electrically driven motor 11, a rotating plate 12 and a cam plate 13 that are attached to rotate together with a rotating shaft 11 a of the motor 11, and a cam. A pair of switch portions 14 that are paired so as to selectively come into contact with and separate from the plate 13 are provided as main components. Specifically, the motor 11 is disposed on the back side of the inner plate S3b of the middle frame S3 and is connected to the electric wiring CUc of the control unit CU. The rotating shaft 11a of the motor 11 penetrates the inner plate S3b forward, and the central portion of the rotating plate 12 and the cam plate 13 are attached to the tip of the rotating plate 12 along the front surface of the inner plate S3b. The cam plate 13 has a substantially disk shape, but is formed with a large-diameter portion 13a and a small-diameter portion 13b having different radii having an angular phase of about 180 ° different from each other. The two switch portions 14 and 14 are attached to the front surface side of the inner plate S3b so as to face each other with the rotation shaft 11a therebetween, and one switch portion 14 contacts the large diameter portion 13a of the cam plate 13. Then, when the switch is turned on, the other switch section 14 is set so as to be turned off by contacting the small diameter section 13b, and the relationship is alternately switched. With the above configuration, each time the remote control unit CUa is operated once, the rotating shaft 11 of the motor 11 rotates at half a rotation (180 °) simultaneously with the rotating plate 12 and the cam plate 13 based on the signal. Become.

In this embodiment, the transmission mechanism D is mainly provided in the middle frame S3 like the driving force generator PG so as to be interposed between the door body S2 of the upper storage S and the door body S2 of the lower storage S. 4 and 5, the motion converting member 21 that converts the driving force generated by the operation of the rotating shaft 11a of the motor 11 into the advancing and retracting motions in the connecting direction of the plurality of storages S, and this operation The transmission shaft member 22 that transmits the advance / retreat operation by the conversion member 21 to the lock mechanism L, the advance / retreat operation of the transmission shaft member 22, and the locking / unlocking operation by the lock mechanism L of the storage S located above and below the transmission shaft member 22. A pair of interlocking members 23 to be interlocked are provided as main components. The motion converting member 21 is formed of an apparently long and narrow plate member in which a base end portion (right end portion in the illustrated example) is rotatably attached to a position near the outer edge from the center of the rotating plate 12. The transmission shaft member 22 is a rod-shaped member extending in the width direction of the storage S, and is supported in a substantially horizontal posture so as to be slidable left and right by a plurality of support members 22s attached to the front side of the inner plate S3b. . And the front-end | tip part of the operation | movement conversion member 21 and the base end part of the transmission shaft member 22 are axially attached so that rotation is mutually possible. The interlocking member 23 is composed of a rotating member 23a having a V-shape in front view and operating by being supported by a support plate 23s attached to the inner plate S3b, and a rod-like projecting and retracting member 23b. The rotating member 23a is composed of a first rotating plate 23a ₁ and a second rotating plate 23a ₂ that are pivotally supported by a rotating central shaft 23a _{3 at} one end with respect to the support plate 23s. It is. The first rotating plate 23a ₁ is rotatable and slidable to the transmission shaft member 22 by a pin 23a ₄ inserted into a long hole (not shown) formed at the end opposite to the rotating central shaft 23a _3. It is pivotally attached as possible. The second rotating plate 23a ₂ is rotatable and slidable to the elevating member 23b by a pin 23a ₅ inserted into a long hole (not shown) formed at the end opposite to the rotating central shaft 23a _3. It is attached to the shaft. The projecting and retracting member 23b is supported by the support plate 23s so as to project and retract in a substantially vertical posture, and is moved up and down in accordance with the rotating operation of the rotating member 23a. Here, the elevating member 23b is set in the middle frame S3 at the immersive position, but at the protruding position, the tip portion passes through the middle frame S3 and enters the storage S arranged vertically. ing. When the door body S2 is not completely closed with respect to the storage body S1, and the projecting member 23b comes into contact with the end surface of the door body S2, the rotating member 23a is idled and projecting. The member 23b is not protruded any more, and the projecting member 23b, the door body S2, and the rotating member 23a are prevented from being damaged. The transmission mechanism D is disposed over the storage S disposed in the lateral direction in the middle frame S3, and is located on the left side in the drawing in response to the two storages S located on the right side in the drawing. The base storage S is also operated.

  As shown in FIGS. 2 and 3, the lock mechanism L disables the operation body 31 provided on the door body S <b> 2 of the storage S and the handle 31 b of the operation body 31 with the door body S <b> 2 in the closed position. A lock body 32 that is fixed or unlocked so as to be operable is provided as a main component.

  In the illustrated example, only the lock mechanism L provided in the storage S located on the upper side in FIG. 1 is illustrated and described in detail. In addition, the configuration of the lock mechanism L provided in the storage S disposed on the lower side is exactly the same as the configuration shown in FIG. In FIGS. 4 and 5, the same reference numerals are used.

The operating body 31 constitutes a part of the opening / closing mechanism of the door body S2, and the specific configuration is as described above. The lock body 32 is pressed from below by the lifting member 23b of the transmission mechanism D and moves upward, thereby prohibiting the operation of the slider 31b of the operation body 31. Specifically, the lock body 32 includes a lock shaft 32a provided in a vertical posture substantially parallel to the synchronization axis Rb of the opening / closing mechanism, and a lock plate 32b fixed to the upper end portion of the lock shaft 32a. The lock shaft 32a and the lock plate 32b are maintained in a vertical posture by a mounting body 33 mounted on the back surface of the door body S2 at a position immediately below the operating body 31. The mounting body 33 is usually disposed using a space set on the inner surface of the door body S2 in order to provide the operating body 31 and the synchronization axis Rb. In particular the locking shaft 32a is urged downward by the bottom wall 33a and the spring 32a ₁ disposed in lower chamber 33c formed between the intermediate wall 33b provided on the upper side of the mounting member 33. The lock plate 32b is provided so as to slide up and down in the first groove portion 33e communicated to the outside in the vertical direction from the upper chamber 33d formed above the intermediate wall 33b of the mounting body 33. when the plate 32b is moved upward is that enters the upper end downwardly to the slider 31b of the operating member 31 into the recess 31b ₁ formed so as to open, moves to the left and right sliders 31b is inhibited I try to do it. That is, in the present embodiment, the position where the lock plate 32b is moved upward and the operation of the slider 31b is prohibited as the lock shaft 32a is pushed by the elevating member 23b of the transmission mechanism D from below. operation is a lock position becomes impossible, the locking operation of the locations of the handle 31a come out of the recess 31b ₁ of the elevating member 23b is accompanied therewith are lowered lock shaft 32a and the locking plate 32b is moved downward slider 31b The release position.

  Further, the lock device LA is provided with a display unit ID indicating whether the lock mechanism L is in the lock position or the lock release position. Specifically, in the storage S, the display unit ID is a pair of notations 32op and 32cl that are separated from each other on the surface of the lock plate 32b and attached with a colored or colored sticker, and one of the pair of notations 32op and 32cl is a door. The display window S2w is formed by opening the door body S2 so as to be visible from the front of the body S2. Here, the upper side of the pair of notations 32op and 32cl is the unlock notation 32op indicating that the lock mechanism L is in the lock position, and the lower side is the lock notation 32cl indicating that the lock mechanism L is in the unlock position. Here, for example, the unlocking notation 32op can be represented by a mark such as a red circle, while the unlocking notation 32cl can be represented by a mark such as a blue or white circle. In addition, characters such as “open” or “OPEN” can be applied to the unlock notation 32op, while characters such as “close” or “CLOSE” can be applied to the lock notation 32cl. While the mark and the characters are applied only to the display, the surface of the lock plate 32b may be shown as it is from the display window S2w in the lock notation 32cl.

Based on the above configuration, the operation of the locking device LA of the present embodiment will be described. First, in the state where the door body S2 of each storage S is positioned at the closed position closed with respect to the storage body S1, when the door S2 is moved from the unlocked state where the door S2 can move to the open position, the remote control device When the button of CUa is operated, the radio signal is transmitted to the motor 11 through the receiving device CUb and the electric wiring CUc, and the rotating shaft 11a, the rotating plate 12 and the cam plate 13 are rotated halfway. Along with this, the motion converting member 21 of the transmission mechanism D rotates and simultaneously moves in the width direction (left side in the illustrated example) of the storage S (FIGS. 4 to 5), and the transmission shaft member 22 in the middle frame S3 stores each of them. It slides in the width direction of the storage S (left side in the illustrated example) (FIGS. 4 to 5). Further, in conjunction with this movement, in the interlocking member 23 provided symmetrically in the vertical direction, the rotating member 23a rotates symmetrically in the vertical direction, and the projecting and retracting member 23b protrudes. As a result, in the lock mechanism L, the lock shaft 32a of the lock body 32 is pushed by the projecting member 23b and moves toward the slider 31b (FIGS. 2 to 3), and the lock plate 32b is recessed in the slider 31b of the operation body 31. By advancing into 31b ₁ (moving from the unlocked position to the locked position), the handle 31a of the operating body 31 becomes inoperable, and the door body S2 is locked. When changing from the locked state to the unlocked state, by operating the button of the remote control unit CUa again, the rotating shaft 11a, the rotating plate 12 and the cam plate 13 of the motor 11 are further rotated halfway, and the subsequent parts are described above. the operation operates in the reverse, locking plate 32b is (moved from the locked position to the unlocked position) exit to the recess 31b inside the _first slider 31b that is, the handle 31a of the operation member 31 becomes operable, the door The body S2 is unlocked and unlocked.

In the lock device LA of the present embodiment, the lock mechanism L is moved from the lock position to the lock release position or from the lock release position to the lock position in the event of an emergency such as a power failure or an electrical system failure. An emergency locking / unlocking mechanism LE that enables forcibly locking / unlocking S2 is provided. That is, the emergency locking / unlocking mechanism LE1 cannot lock the door S2 in the unlocked state because the control unit CU and the driving force generation unit PG1 cannot operate in an emergency as described above, or vice versa. This solves the problem that the door S2 in the locked state cannot be unlocked. Therefore, in this embodiment, the emergency locking / unlocking mechanism LE is realized using the configuration of the transmission mechanism D. In other words, the emergency locking / unlocking mechanism LE1 includes an apparently single motion converting member 21 composed of three plate-like members that are pivotably attached to each other. Specifically, as shown in FIG. 6, the motion converting member 21 includes a motion converting first member 21 a having one end pivotally supported on the rotating plate 12 and a motion converting having one end pivoted to the transmission shaft member 22. A third member 21c and a motion conversion second member 21b interposed between the motion conversion first member 21a and the motion conversion third member 21c and rotatably attached to both of them are configured. More specifically, the base end portion of the motion conversion first member 21a is pivotally attached to the rotating plate 12, while the tip portion is pivotally attached to the base end portion of the motion conversion second member 21b. Further, the distal end portion of the motion converting third member 21c is pivotally attached to the proximal end portion of the transmission shaft member 22, while the proximal end portion is connected to the motion converting first member 21a at the proximal end portion of the motion converting second member 21b. It is axially attached at a position closer to the tip than the axially attached portion. Then, normally, by fixing the distal end portion of the motion conversion second member 21b and the central portion in the longitudinal direction of the motion conversion third member 21c with screws 21d, these three members apparently function as one member. In this case (see FIGS. 4 and 5), in an emergency (FIG. 6 shows a case where a power failure or the like occurs when the lock mechanism L is in the lock position), the screw 21d is removed. Accordingly, the motion conversion second member 21b is rotated (clockwise in the illustrated example) and raised with respect to both the motion conversion first member 21a and the motion conversion third member 21c (see FIG. 6). As a result, the rotation member 23a in the interlocking member 23 is rotated by pulling the motion conversion third member 21c toward the driving force generation unit PG1, and accompanyingly pulling the transmission shaft member 22 toward the driving force generation unit PG, and results for lowering the elevating member 23b, a state in which the locking plate 32b of the lock member 32 respectively is retracted from the recess 31b inside the _first slider 31b to unlock the handle 31a. In this way, even when a power failure or a malfunction of the electric system occurs, the locked state of the door body S2 by the lock mechanism L can be forcibly released. Such an emergency locking / unlocking mechanism LE can be provided for each storage S. In that case, the transmission shaft member 22 is divided, and the parts having the same structure as the motion conversion member 21 described above are arranged between them, so that forced locking / unlocking for each individual storage S can be realized. . As a result, it is possible to reduce the manual operation force required for forced locking and unlocking.

  As described above, the locking device LA according to the present embodiment is provided in each storage S arranged in a plurality of rows in the up and down and left and right directions, and moves the door body S2 that is the opening / closing body in the closed position to the open position. A lock mechanism L that can take a lock position to be prohibited or a lock release position that has been released from the prohibition, a single drive force generator PG that generates a drive force, and a transmission mechanism D that interlocks each lock mechanism L. Therefore, since the plurality of storages S can be unlocked and unlocked at a time by the driving force generated by the driving force generation unit PG transmitted via the transmission mechanism D, it is necessary to individually unlock and unlock the plurality of storages S. Absent. In addition, since the power is mechanically propagated to at least the transmission mechanism D and the lock mechanism L based on the driving force electrically generated in the driving force generation unit PG, the simultaneous locking / unlocking of all the storages is performed by the machine. As long as the driving force generated by the driving force generator PG can withstand the conventional locking device of the type that is automatically performed, simultaneous unlocking can be realized even if more storages S are added. . Furthermore, unlike the embodiment in which all the storages disclosed in Patent Document 2 are electrically locked and unlocked, the electrical configuration is required only at one location around the driving force generation unit PG. As a result, the electrical wiring can be drastically reduced compared to a conventional locking device that electrically locks and unlocks all storage units simultaneously, and there is a possibility of failure such as disconnection. Thus, even if a failure occurs in the electrical system, the failure location can be easily identified. Of course, unlike the same document, since the electrical wiring is reduced and no locking / unlocking device is prepared for each storage, the introduction cost can be lowered as a result.

  Further, by providing the lock mechanism L with the operation body 31 and the lock body 32, the lock mechanism L can be suitably used for the storage S having a general structure including the door body S2. The driving force generator PG has a rotating shaft 11a that rotates by the driving force, and the transmission mechanism D is composed of the motion conversion member 21 and the transmission shaft member 22, so that the power transmission mechanism is relatively It can be simple. Further, since the transmission mechanism D is provided with the interlocking member 23 that interlocks the advance / retreat operation of the transmission shaft member 22 and the operation of the lock body 32, the driving force transmitted to the transmission shaft member 22 is suitably applied to the lock body 32. To communicate.

  In particular, in this embodiment, the transmission shaft member 22 constituting the transmission mechanism D is arranged so as to extend in the horizontal direction so that the plurality of storages S are connected in the horizontal direction, and the storage that is arranged continuously in the vertical direction. The transmission shaft member 22 is disposed between the door bodies S2 of the S so that the driving force is suitably transmitted not only to the lateral direction but also to the lock mechanism of the storage S located in the vertical direction. Realized.

  Moreover, the lock | rock state of the storage S can be easily discriminate | determined by providing display part ID in the door body S2. In particular, by providing a display window on the door body S2 so that the lock release notation 32op and the lock notation 32cl marked on the lock body can be seen from the display window S2w, the lock device LS is locked at a glance for the user. It has become very convenient because the state becomes clear.

  As mentioned above, although embodiment of this invention was described, the specific structure of each part is not limited only to embodiment mentioned above. For example, in the above embodiment, the driving force generation unit PG and the transmission mechanism D are arranged in the middle frame S3 separate from the storage S, but the driving force generation unit PG and the transmission mechanism D are on the upper side. It is good also as a structure arrange | positioned in the arrange | positioned storage S. FIG. In the present embodiment, the control unit CU capable of wireless remote operation is applied to the driving force generation unit PG. Instead, an appropriate interface such as an electronic lock device using an electronic dial, an electronic key, a touch panel, or the like is used. It is also possible to select and apply. Further, when a large number of transmission shaft members are connected in the lateral direction, a configuration in which a plurality of transmission shaft members are connected using a connecting member or the like may be employed. In that case, even if any of the connecting shaft members breaks and becomes unusable, only that member can be easily replaced. In addition, various modifications can be made without departing from the spirit of the present invention.
