Description

  The present invention relates to a mobile rack apparatus that can provide an accurate individual security function between racks.

  For example, as shown in Patent Document 1, this type of mobile rack apparatus is a rack that faces a passage by a user moving the rack as necessary and entering a passage formed between adjacent racks. It is configured so that articles can be taken in and out of the storage space, and is characterized in that it can save space compared to a fixed rack device.

On the other hand, in order to ensure security when documents and articles are stored in such a mobile rack device, a device that is locked so as not to open between racks is known. This is usually configured so that all racks can be locked together so that they cannot be opened, or can be released simultaneously.
JP 2000-37238 A

  By the way, in a relatively large organization, there is a case where it is desired to store the stored item only in a storage space facing a predetermined passage for each group so that the mobile rack device can be shared by a plurality of groups. In such a case, since the conventional mobile rack apparatus only locks / unlocks the entire rack, there is a problem that security for each passage is not ensured. It is essential to take some measures.

  In order to eliminate such inconvenience, for example, in the case of an electric mobile rack apparatus, an appropriate program is incorporated in a control panel for controlling the electric motor, and if the authentication information is not input in units of racks, the electric motor is locked. However, it is possible to prevent the clutch from being released or to prevent the clutch from being connected. Further, in the case of a manual type moving rack device, it is possible to cope with the structure by fixing the chain connecting the handle and the wheel so as not to move. However, it is inefficient to handle each rack type differently in this way, and it is inefficient even if it is a manual type (that is, a type in which the rack is moved by pressing by hand) ) Must adopt a structure other than the above. Furthermore, even if a lock function is provided, it is difficult to say that individual security is perfect if it can be easily broken or unlocked.

  The present invention has been made paying attention to such a problem, and can be configured without depending on the drive type of the rack so that an accurate individual security function can be provided between arbitrary racks. It is an object.

  In order to achieve this object, the present invention takes the following measures.

In other words, the mobile rack device of the present invention is configured such that a plurality of racks can be moved along the rails, and between adjacent racks can be opened to form a passage between the racks. A lock mechanism having an actuator is provided at a substantially central position in the depth direction on one end side in the direction, and a lock receiving portion is provided at a corresponding position on the other end side, while an operation unit is provided on the outer surface orthogonal to the rack moving direction, and the rack A transmission mechanism that transmits an operation force input to the operation unit to the lock mechanism is provided in part, and one or the periphery of the lock receiving unit or the actuator has an inner space that receives the other. and, either the inner hollow portion forms a bag shape, or leave configured such forms at least the operating portion in a closed shape, one closes the rack between at least adjacent When the unlocking operation is performed on the operation unit from the state in which the operating member of the lock mechanism attached to the rack is engaged with the lock receiving portion attached to the other rack so as not to be separated The actuator is configured to be disengageable from the lock receiving portion of the adjacent rack.

  In such a case, the actuator of the lock mechanism and the lock receiving portion form an engagement structure between the end portions of the rack that closely face each other. It is also difficult to insert a rod or the like from a direction orthogonal to the moving direction by using the clearance. For this reason, it is possible to effectively realize a lock structure that can simplify the structure and ensure individual security. In addition, since the lock mechanism of the present invention has a structure that does not depend on the drive system of the rack, it can be applied regardless of the type of rack, and is located at a substantially central position in the depth direction. Even when provided, the connection to the locking mechanism can be facilitated.

In addition, the lock receiving portion includes a hollow portion inner accept actuator, or the inner hollow portion forms a bag shape, or since no at least the operation unit side to the closed configuration, unjust locking mechanism The unlocking operation can be accurately prevented .

  At that time, in order to reliably pull the rack into the locked state, it is effective to provide a guide for bringing the operating element into the inner space between the lock receiving portion and the lock mechanism.

  As a specific embodiment, there is a configuration in which the actuator is configured to rotate about an axis parallel to the moving direction of the rack so as to be engaged with and disengaged from the lock receiving portion.

  Alternatively, the actuator is configured so as to be able to swing around an axis perpendicular to the moving direction, and the swinging motion is caused by interfering with the lock receiving portion when engaged to enter the inner space. The thing comprised so that it may be mentioned is mentioned.

  In order to increase the degree of design freedom and select an appropriate operation position according to the situation of the installation location, the lock mechanism is provided with an operation force input end that rotates about an axis parallel to the movement direction. It is preferable that the operation unit can be connected to the force input end from any outer surface orthogonal to the moving direction of the rack through a wire tube structure.

  In the above, instead of providing an inner space for receiving the actuator in the lock receiving portion, an inner space for receiving the actuator is provided in the peripheral portion of the lock receiving portion, or the lock receiving portion is received in the actuator side or its peripheral portion. You may comprise so that an inner space part may be provided.

  Since the present invention has the configuration described above, it can be applied regardless of the drive type of the rack, can be individually opened and closed between arbitrary racks, and can effectively secure individual security. Can be provided.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  The mobile rack apparatus of this embodiment is used as a library or a warehouse. As shown in FIGS. 1 to 3, a plurality of racks 2 are arranged on rails 1 laid on the floor, and these racks 2 are used as rails. 1 is movable. The rack 1 located at the lower left is disposed adjacent to a wall or the like (not shown).

  Each rack 2 includes a carriage 3 and a main body portion 20 disposed above the carriage 3. The trolley 3 assembles the bottom frame members 30a, 30b in the longitudinal direction and the bottom frame members 31, 31 in the short direction, which form a pair of inwardly U-shaped, into a frame shape, and appropriately reinforces the portion by the reinforcing frame member 32, A pair of wheels 60 and 61 are assembled at both ends in the moving direction. And the support | pillar insertion hole 33 which makes a planar view rectangular shape is provided in the upper surface several places of this trolley | bogie 3. As shown in FIG.

  The wheels 60 and 61 are positioned in the wheel receiving holes of the mounting member 32a provided in parallel to the reinforcing member 32, and a drive shaft 60a that pivots between the wheels 60 and 60 rotates between the reinforcing members 32a and 32a. It is supported as possible.

  On the other hand, the main body 20 includes a column 21 erected by inserting a lower end into the column insertion hole 33, left and right side plate portions 22 provided in the short direction of the carriage 3, and upper ends of the column 21 and the side plate portion 22. And a top plate portion 23 provided in the section, and a shelf plate 24 is bridged at an appropriate position.

  In the present embodiment, the racks 2 (T) located at both ends in the moving direction open the shelf space only on one side, while the other racks 2 open the shelf space on both ends in the moving direction. .

  In order to drive such a rack 2, in the present embodiment, the manual handle 41 pivotally supported on the side plate portion 22 of the rack 2 and the driving force input to the manual handle 41 are located on one end side in the movement direction. A drive mechanism 4 including a transmission mechanism 42 for transmitting to the wheel 60 is provided.

  The transmission mechanism 42 includes a transmission shaft 42a installed in parallel with the drive shaft 60a between the reinforcing members 32a and 32b, and a first transmission element 42b that transmits an operation force input to the manual handle 41 to the transmission shaft 42a. The second transmission element 42c transmits the rotational power of the transmission shaft 42a to the drive shaft 60a. Appropriate mechanical parts such as sprockets and chains can be used for both transmission elements 42b and 42c.

  That is, one wheel 60 is directly driven by transmitting an operation force input to the manual handle 41, and the other wheel 61 is driven by the wheel 60. A path can be selectively formed between the racks 2 and 2 by opening and closing between the racks 2 and 2.

In such a configuration, as shown in FIGS. 2 to 7, this embodiment is provided with a lock mechanism 7 having an actuator 72 at a substantially central position in the depth direction on one end side in the moving direction of the rack 2, and corresponding on the other end side. While the lock receiving portion 8 is provided at the position, the operation portion 5 that can be operated with the key K on the side plate 22 that is the outer surface orthogonal to the moving direction of the rack 2 and the operation force input to the operation portion 5 are A transmission mechanism 9 for transmitting to the lock mechanism 7 is provided.

  More specifically, the lock mechanism 7 includes a shaft 71 that is rotatably attached to the vertical surface of the bottom frame member 30a constituting the carriage 3 in the moving direction of the rack 2 as shown in FIG. A rectangular parallelepiped actuator 72 provided integrally with the outer end of the shaft 71 and extending in a direction perpendicular to the shaft 71, and a position provided in a part of the shaft 71 so as to be integrally rotatable and displaced in the radial direction. And an operation force input end 73 provided with a wire connection portion 73a for receiving an operation force transmitted from the transmission mechanism 9. The actuator 72 is located between a substantially vertical unlock position and a substantially horizontal lock position. It is designed to be driven by rotation.

  The lock receiving portion 8 is attached to a corresponding portion of the shaft 71 on the vertical surface of the bottom frame member 30b constituting the carriage 3, and includes a side wall 81 protruding from the vertical surface, and a top wall 82 continuous to the side wall 81. have. The top wall 82 is provided with a rectangular through window 82a that permits passage of the actuator 72 in the unlocked position and prohibits passage of the actuator 72 in the locked position, and rotates the actuator 72 inward. The inner space 83 is large enough.

  By changing the direction of the actuator 72 and the direction of the through window 82a of the lock receiving portion 8, the actuator 72 is set to the unlocked position in a substantially horizontal state and to the locked position in a substantially vertical state. May be.

On the other hand, the operation unit 5 is provided on the side plate 22 of the rack 2 and can be rotated between a locked position and an unlocked position by a locking operation, and an L-shaped attachment attached to a shaft portion of the locking cylinder 51. A rotation lever 52 and a tension spring 53 as an urging means for urging the rotation lever 52 in the unlocking direction are provided. The lock cylinder 51 has been rotatable operation by inserting the key K, the lock cylinder 51 is locked position, it is possible to pull out the key K also when it is in any state of the unlocked position If the key K is removed when the lock cylinder 51 is in the lock position, the rotation of the lock cylinder 51 is locked.

  And the transmission mechanism 9 is made into the wire tube structure which consists of the wire tube 91, the fixing | fixed part 92a, 92b which fixes this wire tube 91 to an appropriate position, and the wire 93 penetrated by the wire tube 91, One end is connected to a wire connection portion 52 a set at a position displaced from the axis of the rotation lever 52, and the other end is connected to a wire connection portion 73 a provided at the operation force input end 83 of the lock mechanism 7. . The fixing portion 92b uses an upright wall b of the bracket B having an upward U-shape, and the wire 93 can be connected to the wire connecting portion 73a regardless of which of the standing walls b is used as the fixing portion 92b.

That is, when the key K is inserted into the lock cylinder 51 and is rotated during locking, the rotating lever 52 rotates to push out the wire 93, whereby the actuator 72 of the lock mechanism 7 is moved from the vertical position shown in FIG. Rotate approximately 90 ° until. When the key K is removed in this state, the lock cylinder 51 is locked so as not to rotate, and the actuator 72 is held in the locked state. Next, when unlocking from this state, the key K is inserted into the lock cylinder 51 and rotated in the reverse direction, so that the rotating lever 52 is rotated while being assisted by the spring 53, thereby pulling the wire 93, and thereby the locking mechanism. 7 actuator 72 rotates approximately 90 ° from the horizontal posture to the vertical posture. When the key K is extracted in this state, the lock cylinder 51 is locked again so as not to rotate, and the actuator 72 is held in the unlocked state.

  Therefore, as shown in FIGS. 5 and 6, the adjacent racks 2, 2 are closed close to each other to close the operating element 72 into the inner space 83 of the lock receiving portion 8 through the through window 82 a, and the state When the above-described locking operation is performed, the actuator 72 of the lock mechanism 7 attached to one rack 2 is separated into the lock receiving portion 8 attached to the other rack 2 as shown by an imaginary line in FIGS. It can be engaged so as not to obtain. For this reason, separation between the racks 2 and 2 is prohibited. When the unlocking operation is performed from this state, the actuator 72 of the lock mechanism 7 can be disengaged from the lock receiving portion 8 of the adjacent rack, whereby the rack 2, It becomes possible to open between two.

  In the movable rack apparatus of the present embodiment configured as described above, the actuator 72 of the lock mechanism 7 and the lock receiving portion 8 are engaged between the end portions of the racks 2 and 2 that closely face each other. Therefore, the racks 2 and 2 are forcibly opened, or the clearance between the racks 2 and 2 is used to provide little room for inserting a bar or the like from a direction perpendicular to the moving direction. For this reason, the individual security function that allows the opening and closing of the passage only to a specific person can be effectively given with simple structure and easy operation. Moreover, since the lock mechanism 7 and the like have a structure that does not depend on the drive system of the rack 2, it can be applied regardless of the type of the rack 2 (both electric type and manual type), and a different lock structure for each type. Cost reduction and the like can be effectively achieved as compared with the case of employing. In addition, since the lock mechanism 7 is located at a substantially central position in the depth direction and the operation unit 5 is provided on any of the side plates 22 paired in the depth direction, the connection condition to the lock mechanism 7 is substantially equivalent. The operation unit 5 can be effectively positioned on an appropriate side of the pair of side plates 22 positioned at the end in the depth direction in accordance with the location of the rack device.

  In addition, the lock receiving portion 8 guards the inner space 83 that receives the operating element 72 by the side wall 81, and the inner space 83 is closed when viewed from the side plate 22 side on which the operation unit 5 is provided. Therefore, an illegal unlocking operation for directly operating the lock mechanism 7 can be effectively blocked, and the effectiveness of the individual security function can be ensured. A similar effect is obtained in that the operating force input end 73 is shielded from the side by the fixing portion 92 b of the wire 93.

  Further, the actuator 72 is configured to rotate about the axis of the shaft 72 provided in parallel with the moving direction of the rack 2 so as to be engaged with and disengaged from the lock receiving portion 8 and orthogonal to the moving direction of the rack 2. Since it is substantially difficult to impart an unreasonable rotational motion to the shaft 72 from the direction in which it is performed, the effect of further enhancing the individual security function is produced in combination with the presence of the side wall 81 and the like.

  In particular, the lock mechanism 7 is provided with an operating force input end 73 that rotates about an axis parallel to the moving direction, and the operating force input end 73 is moved in the moving direction of the rack 2 via a transmission mechanism 9 having a wire tube structure. Since the operation unit 5 can be connected from any side plate 22 side orthogonal to the lock plate 7, the situation where the mobile rack device is installed is coupled with the presence of the lock mechanism 7 at the substantially central position in the depth direction. Accordingly, it is possible to easily realize a configuration in which an appropriate position of the operation unit 5 is selected or the operation unit 5 is provided on both side plates 22 so that locking / unlocking can be performed from either side.

  In addition, a structure similar to the lock receiver 8 is attached as an actuator to the shaft 71 of the lock mechanism 7 and rotated, and the structure similar to the actuator 72 is fixed using a fixed shaft, thereby locking the lock receiver. As a structure, the lock receiving portion may be received on the actuator side.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Of the portions common to the above-described embodiment regarding the structure of the rack 2 and the like, the description of portions that do not require a particular description is omitted.

  This movable rack apparatus is provided with a lock mechanism 107 having an actuator 172 having a latch structure as shown in the figure at a substantially central position in the depth direction on one end side in the moving direction of the rack 2, and a lock receiving portion at a corresponding position on the other end side. 108 is provided. Then, with the adjacent racks 2, 2 being closed, the actuator 172 of the lock mechanism 107 attached to one rack 2 is engaged with the lock receiving portion 108 attached to the other rack 2 so as not to be separated. I am doing so. Further, when the same unlocking operation as in the above embodiment is performed from that state, the actuator 172 of the lock mechanism 107 can be disengaged from the lock receiving portion 108 of the adjacent rack 2.

  That is, the lock mechanism 107 of this embodiment is provided with a latch claw portion 172a that is folded back like a hook at the tip of the actuator 172, and the actuator 172 is attached to a shaft 171 orthogonal to the moving direction. The latch claw portion 172a is configured to swing around in the vertical direction. A winding spring 175 is provided on the shaft 171, and the periphery of the actuator 172 is accommodated in a cover 174 that protrudes in a tapered shape from the vertical surface of the bottom frame member 30 a, and from a window 174 a provided at the tip of the cover 174. The latch claw 172a is exposed to the outside. The base end of the actuator 172 is connected to a wire 93 that pushes and pulls the bottom end of the bottom frame member 30a in the vertical direction. On the other hand, the lock receiving portion 108 has an inner space 183 formed therein together with a tapered recess 184 corresponding to the cover 174, and the actuator 172 is provided on the reinforcing plate 182 located at the bottom of the recess 184. A penetrating window 182a that can be inserted while swinging the tip claw portion 172a is provided. A resin material is used for the lock receiving portion 108 of this embodiment so as to perform a buffering action at the time of collision.

  When the racks 2 and 2 are brought close to each other, the latch claw portion 172a of the actuator 172 constituting the lock mechanism 107 is caused to interfere with the inner edge of the through window 182a of the lock receiving portion 108, and at that time, the latch claw portion 172a Using the folded portion as a guide, the actuator 172 is caused to swing in the vertical direction, thereby causing the latch claw 172a to enter the inner space 183, and at the entered position, the actuator 172 is moved back to the original position by the winding spring 175. By returning to the position, the tip claw portion 172a can be engaged with the inner surface of the reinforcing plate 182 as indicated by an imaginary line in FIG.

With such a latch structure, the racks 2 and 2 can be automatically pulled into a locked state just by bringing the racks 2 and 2 close to each other, so that the individual security function can be reliably ensured without performing a separate locking operation. it can. Since the inner space 183 has a bag shape, it is possible to reliably block an unauthorized unlocking operation for a person who does not have the key K to directly operate the lock mechanism 107, and to perform the individual security function effectively. Can be secured.

  In addition, when the racks 2 and 2 are brought close to each other, the tapered cover 174 of the lock mechanism 107 is taper-engaged with the tapered recess 184 of the lock receiving portion 108, and these serve as a guide. Even if there is a slight misalignment between the two, the actuator 172 can be reliably guided to the inner space 183 by the guide action, and the racks 2 and 2 can be reliably pulled into the locked state. In particular, as described, the mobile rack apparatus according to the present embodiment is such that the lock mechanism 107 and the lock receiving portion 108 are provided substantially at the center in the depth direction of the rack 2 and are not easily affected by the skew of the rack 2. However, in combination with this, the above guide action works effectively.

  In the illustrated example, the latch-structured actuator 172 is configured to engage with the through window 182a of the lock receiving portion 108 by performing an up-and-down swing operation. The lock receiving portion 108 may be configured to engage with the through window 182a.

  Next, a third embodiment of the present invention will be described with reference to FIG. Of the portions common to the above-described embodiment regarding the structure of the rack 2 and the like, the description of portions that do not require a particular description is omitted.

  This movable rack apparatus is provided with a lock mechanism 207 having an actuator 272 having a latch structure as shown in the figure at a substantially central position in the depth direction on one end side in the moving direction of the rack 2, and a lock receiving portion at a corresponding position on the other end side. 208 is provided. Then, with the adjacent racks 2, 2 being closed, the operating element 272 of the lock mechanism 207 attached to one rack 2 is engaged with the lock receiving portion 208 attached to the other rack 2 so as not to be separated. I am doing so. Further, when the same unlocking operation as in the above embodiment is performed from that state, the actuator 272 of the lock mechanism 207 can be disengaged from the lock receiving portion 208 of the adjacent rack 2.

  That is, the lock mechanism 207 of this embodiment is provided with a latch claw portion 272a that is folded back like a hook at the tip of the actuator 272, and an axis perpendicular to the moving direction via the intermediate member 271a having an angle shape. The latch claw portion 272a swings in the vertical direction around the shaft 271. A tension spring 275 is engaged with the intermediate member 271a, and elastically urges the latch claw portion 272a of the actuator 272 in a direction in which it swings downward. The periphery of the actuator 272 is accommodated in the bottom frame member 30a of the rack 2 as shown in the figure, and the latch receiving portion 208 of the rack 2 adjacent to the window 274a provided on the vertical surface of the bottom frame member 30a is placed at the bottom. It is designed to be pulled into the inner space of the frame member 30a. An arm 271a projects from the shaft 271 on which the operating element 272 is attached via the intermediate member 271a. The arm 270a is pulled by the wire 293 via the link members 276a and 276b, and the latch claw portion 272a is pulled. The head is swung upward. The arm 271a and the link members 276a and 276b constitute a four-point link mechanism, and the operating force input to the wire 293 is transmitted to the shaft 271 as a rotational force.

  On the other hand, the lock receiving portion 208 is protruded outward from the vertical surface of the bottom frame member 30b of the rack 2 at a portion corresponding to the latch claw portion 272a of the actuator 272, and the linear member is subjected to plastic deformation processing. Then, it is formed in a U shape in a plan view.

  When the distance between the racks 2 and 2 is reduced as indicated by the arrow Y1 in the figure, the lock receiving portion 208 attached to one rack 2 is caused to enter the window 274a attached to the other rack 2 to receive the lock receiving portion. The latch claw portion 272a of the operating element 272 interferes with the horizontal bar 208a located at the tip of the portion 208. This causes the actuator 272 to swing upward as indicated by arrow Y2 using the folded portion of the latch claw portion 272a as a guide, and the tension spring 275 at a position where the latch claw portion 272a gets over the horizontal bar 208a. Thus, the head is swung in the reverse direction (downward) and engaged with the horizontal bar 208a.

With such a latch structure, the racks 2 and 2 can be automatically pulled into a locked state just by bringing the racks 2 and 2 close to each other, so that the individual security function can be reliably ensured without performing a separate locking operation. it can. Since the actuator 272 is inside the bottom frame member 30a and is shielded from the surroundings, an unauthorized unlocking operation in which a person who does not have the key K tries to directly operate the lock mechanism 207 is surely blocked. Therefore, the effectiveness of the individual security function can be ensured.

  Then, when the unlocking operation is performed in the direction of pulling the wire 293, the link members 276b and 276a are rotated as indicated by arrows Y4 and Y3 in the drawing, whereby the actuator 272 is moved via the shaft 271 and the intermediate member 271a. The upward swinging motion of the latch claw 272a is induced, the engagement between the latch claw 272a and the latch receiving portion 208 is released, and the racks 2 and 2 can be opened.

  Although the three embodiments of the present invention have been described above, the specific configuration of each part is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
