<Cylinder lock>
Returning to FIG. 2, the cylinder lock 50 is attached to the other end 30f in the width direction of the door 30. The illustrated cylinder lock 50 is a cam lock type cylinder lock, and includes a cylindrical cylinder portion 51 penetrating the door 30 in the thickness direction. The cylinder part 51 includes a hollow cylindrical cylinder (outer cylinder, not shown), a cylinder plug (inner cylinder, not shown) housed in the hollow part of the cylinder so as to be relatively rotatable, and a forward and reverse direction integrally with the cylinder plug. And a lock piece 53 that rotates (oscillates).
The lock piece 53 is exposed on the side of the housing portion 19 of the housing body 10, and is rotated to be displaced between an unlocked position allowing the door 30 to be opened and closed and a locked position maintaining the door 30 in a closed state. The lock piece 53 is locked in place on the vertical frame 15 when the door 30 is closed and the door 30 is in the locked position, thereby maintaining the door 30 in the closed state.
The cylinder plug has a keyhole for receiving a key. By inserting a key having a predetermined shape through the keyhole and rotating the key, the cylinder plug and the lock piece 53 rotate integrally with the key. That is, the lock piece 53 can be rotated from the outside of the equipment storage rack 1 to the unlocked posture and the locked posture. The cylinder plug and the key for rotating the cylinder plug function as operating means for rotating the lock piece between the unlocked position and the locked position.

<Link means>
The link means 60 is a means for transmitting the rotation operation (driving force) input from the cylinder plug of one cylinder lock 50a to the lock piece 53 to the lock piece 53 of the other cylinder lock 50b. The link means 60 shown in this example transmits the operation of the lock pieces 53, 53 of the cylinder locks 50a, 50b to each other. The link means 60 is arranged inside the equipment storage rack 1.
In this example, the pair of doors 30a and 30b provided with the cylinder locks 50a and 50b in which the posture displacements of the lock pieces 53 and 53 are linked (linked) to each other by the linking means 60 are one ends in the width direction. The portions 30e, 30e are each axially supported by a common vertical frame 15a of the housing body 10. Note that if the widthwise end portions 30e, 30e of the doors 30a, 30b are arranged adjacent to or close to each other, the posture of the lock pieces 53, 53 even if the frames supporting the doors 30a, 30b are different from each other. It is possible to transfer the displacement to each other.

The link means 60 includes a pulley 61a that rotates integrally and coaxially with the lock piece 53 of the cylinder lock 50a, a lock gear 63 that rotates integrally and coaxially with the lock piece 53 of the cylinder lock 50b, and a mesh with the lock gear 63 and the door. The idle gear 65 is rotatably supported by the idle gear 65 so as to rotate integrally and coaxially with the idle gear 65, the pulley 61b fixed to the idle gear 65 so as to rotate coaxially with the idle gear 65, and the pulley 61a, 61b. A link wire 67.
The pulley 61a is supported by the cylinder lock 50a. The lock gear 63 is supported by the cylinder lock 50b.
The illustrated link wire 67 has an endless shape, and a part (in a suitable place) is fixed to the pulley 61a, and the other part (in a suitable place) is fixed to the pulley 61b. The link wire 67 shown in this example is made of a wire that can be bent or bent. The shape and material of the link wire 67 are not limited as long as the driving force can be transmitted. However, in order to prevent a short circuit accident due to contact between the link wire 67 and the electric device, an insulative material is used for the link wire 67, or a link wire 67 in which a conductive metal wire is coated with an insulating coating is used. It is desirable to use
Further, a toothed pulley may be used instead of the pulley 61, and a geared belt may be used instead of the link wire 67. Further, a non-bendable or non-bendable link piece may be used instead of the link wire 67. The intermediate portion of the link wire 67 is supported and relayed by a support means 68 provided at an appropriate position of the housing body 10 (for example, at an appropriate position of the vertical frame 15a) as necessary.

  In this example, since the cylinder lock 50 and the link means 60 are attached to the door 30, there is no limitation on the position of the cylinder lock 50 in the vertical direction of the door 30. In addition, even if the cylinder lock 50 is disposed at an intermediate portion in the vertical direction of the door 30, it is not necessary to add a new horizontal frame or the like on the housing body 10 side, and the air circulation in the equipment housing rack 1 is obstructed. You can enjoy the advantage of not having.

FIGS. 4A to 4C are diagrams illustrating the operation of the lock pieces and the link means. FIG. 4A is a plan view showing a part of the device accommodation rack in a developed state. FIGS. 4B and 4C are elevation views corresponding to FIG. 4A, FIG. 4B is a view of the lock piece observed from the housing section side, and FIG. FIG.
As shown in FIG. 4B, the lock piece 53 of the cylinder lock 50a is rotated from the outside of the equipment housing rack 1 to be displaced from the unlocked position (solid line) to the locked position (broken line) (the direction of the arrow A1 in the figure). .
As shown in FIG. 4C, the driving force in the direction of arrow A1 for displacing the lock piece 53 of the cylinder lock 50a in the posture is transmitted to the pulley 61b and the idle gear 65 via the pulley 61a and the link wire 67. The direction of the driving force is reversed by the lock gear 63 meshing with the idle gear 65, and becomes the driving force in the direction of arrow A2. As shown in FIG. 4B, the lock piece 53 of the cylinder lock 50b is rotated and displaced from the unlocked posture (solid line) to the locked posture (dashed line) by the driving force in the direction of the arrow A2.
Similarly, when the lock piece 53 of the cylinder lock 50a is displaced from the locked position (broken line) to the unlocked position (solid line) in the direction of the arrow B1 in the figure, the driving force is transmitted by the link means 60, and the lock piece of the cylinder lock 50b is similarly moved. 53 can be displaced from the locked position (broken line) to the unlocked position (solid line) in the direction of arrow B2 in the figure.
In this example, the link wire 67 is wound around the pulley 61a and the pulley 61b in an endless manner, and the link wire 67 is fixed in place to the pulley 61a and the pulley 61b, respectively. The driving force is also transmitted to the lock piece 53 of the cylinder lock 50a when operated.

<Joint part>
Joints 69, 69 (disconnection means) for freely connecting and disconnecting (cutting or connecting) the link wire 67 are arranged at appropriate places in the middle of the link wire 67. The joint 69 switches the transmission state of the driving force. That is, when the joint 69 is in an integrally connected state, the driving force can be transmitted between the lock piece 53 of one cylinder lock 50a and the lock piece 53 of the other cylinder lock 50b. When the cutting state is released, the driving force cannot be transmitted.
The joint 69 can be configured to include, for example, a hollow female member and a male member inserted into the hollow portion of the female member. The male member may be provided with a locking claw that is elastically displaced or protruded or retracted in the inner and outer radial directions, and the female member may be provided with a locked portion to which the locking claw or the like is locked. Alternatively, the joint 69 may be configured by a ring-shaped member, a carabiner or the like locked on the ring-shaped member. The joint 69 may have any shape and mechanism as long as it can connect and disconnect the link wire 67, and its material is not limited, but it is desirable that the joint 69 has at least an insulating property.
By providing the joint 69 at an appropriate position in the middle of the link wire 67, the link wire 67 can be temporarily divided or deformed into an end shape, so that the door 30 and the link wire 67 can be separated. . Therefore, even when the link means 60 is disposed on the door 30 side, the door 30 can be removed from the housing body 10.

<Effect>
According to this embodiment, since the driving force for operating the lock piece 53 of the cylinder lock 50a is transmitted to the lock piece 53 of the cylinder lock 50b connected by the link means 60 and driven, the drive force is provided on one door 30a. By locking / unlocking the cylinder lock 50a, the locking / unlocking operation of the cylinder lock 50b provided on the other door 30b can also be performed.
In the present embodiment, the linking means 60 is different from the locking piece 53 for performing the locking operation and the locking piece 53 for performing the unlocking operation in order to mutually transmit the operations of the locking pieces 53, 53 of the cylinder locks 50a, 50b. May be. That is, for example, even when the lock pieces 53 of the cylinder lock 50a and the cylinder locks 50b are displaced to the locking posture by operating the lock pieces 53 of the cylinder lock 50a, the lock pieces 53 of the cylinder lock 50b are disengaged. By operating the cylinder lock 50a, the lock pieces 53, 53 of the cylinder lock 50a can be displaced to the unlocking posture.
In the present embodiment, the lock piece 53 is displaced between the locked position and the unlocked position by the rotation, but the rotation of the cylinder plug constituting the cylinder portion 51 is changed to the driving force to reciprocate in the horizontal direction by the pinion gear and the rack gear. Then, the lock piece may be displaced between the locked position and the unlocked position by horizontal movement. In this case, the rotation of the cylinder plug constituting one cylinder lock is transmitted to the cylinder plug constituting the other cylinder lock by a link wire.

[Second embodiment]
FIGS. 5A and 5B are diagrams showing an equipment storage rack according to the second embodiment of the present invention, wherein FIG. 5A is a plan view and FIG. 5B is a schematic diagram for explaining the operation of the link means.

The device housing rack according to the second embodiment has the same opening and closing direction of the door as the first embodiment, but is characterized in that the positional relationship between the doors to which the locking / unlocking operation is linked by the link means is different. . That is, in the first embodiment, the operation of the lock piece 53 is linked between the door 30a and the door 30b that are supported by the common vertical frame 15a of the housing body 10. On the other hand, in the second embodiment, between the door 30a and the door 30d whose other end 30f (door tip) in the width direction approaches or separates from the common vertical frame 15d of the housing body 10. To link the operation of the lock pieces 53.

<Link means>
In the equipment storage rack 2, the link means 70 includes a bevel gear 71a that rotates integrally and coaxially with the lock piece 53 of the cylinder lock 50a, and a bevel gear 71d that rotates integrally and coaxially with the lock piece 53 of the cylinder lock 50d. , Is provided.
The bevel gear 71a is supported by the cylinder lock 50a of the door 30a, and the bevel gear 71d is supported by the cylinder lock 50d of the door 30d. That is, also in this example, the cylinder lock 50 and the link means 70 are attached to the door 30.
The bevel gear 71a and the bevel gear 71d are separated from each other when one of the doors 30 is opened, so that the driving force cannot be transmitted. When both the doors 30a and 30d are closed, the bevel gear 71a and the bevel gear 71d are engaged to transmit the driving force. The connection state becomes possible. When both the doors 30a and 30d are closed, the rotation center axes of the bevel gears 71a and 71d are attached to the two doors 30a and 30d so as to be orthogonal to each other, and the two bevel gears 71a and 71b are interposed between two intersecting axes.

As shown in FIG. 5B, in a state where the doors 30a and 30d are closed, the lock piece 53 of the one cylinder lock 50a is changed from the unlocked position (solid line) to the locked position (solid line) from outside the equipment housing rack 2. (Broken line) (in the direction of arrow A1 in the figure). The driving force in the direction of the arrow A1 is transmitted from the bevel gear 71a to the bevel gear 71d meshing therewith as a driving force in the reverse rotation direction (the direction of the arrow A2) to unlock the lock piece 53 of the other cylinder lock 50d (solid line). To the locking posture (broken line) (in the direction of arrow A2 in the figure).
Conversely, the same applies to the case where the lock piece 53 of one cylinder lock 50a is displaced in the arrow B1 direction from the locked position (broken line) to the unlocked position (solid line). Similarly, when the lock piece 53 of the other cylinder lock 50d is operated in the locking / unlocking direction, the driving force can be transmitted to the lock piece 53 of one cylinder lock 50a.

<Effect>
As described above, according to the present embodiment, the driving force for operating the lock piece 53 of one cylinder lock 50a is transmitted to and driven by the lock piece 53 of the other cylinder lock 50d connected by the link means 70. Therefore, the locking / unlocking operation of one cylinder lock 50a can also perform the locking / unlocking operation of another cylinder lock 50d.
Further, in the present embodiment, since the configuration does not include the link wire, the configuration is simple, and the driving force is smoothly transmitted. In addition, it is not necessary to connect / disconnect (or attach / detach) the link wire when attaching / detaching the door, and the work efficiency is improved.
Further, similarly to the first embodiment, by operating any one of the lock pieces and displacing to the locking / unlocking posture, the other lock pieces linked by the link means are displaced to the locking / unlocking posture. be able to. Further, the lock piece operated at the time of locking and the lock piece operated at the time of unlocking may be different.

[Third embodiment]

Further, the third embodiment differs from the first and second embodiments in the opening and closing directions of the door. That is, the housing body 10 according to the present embodiment has a configuration in which the four vertical frames 15a to 15d pivotally support the doors 30a to 30d, respectively, and the doors 30a to 30d are symmetrical by 90 degrees as shown in FIG. Or it is arranged so as to conform to this.

<Link means>
The link means 80 includes a door-side clutch member 81 (first gear) as a member supported by the door 30. The link means 80 includes a body-side clutch member 83 (second gear), a pulley 85, and a link wire 87 (transmission member) as members supported by the housing body 10.
The door-side clutch member 81 is rotatably supported by the cylinder lock 50 so as to rotate coaxially and integrally with the lock piece 53. That is, the door-side clutch member 81 is supported by the door 30.
The body-side clutch member 83 is rotatably supported by the housing body 10 so as to mesh with the door-side clutch member 81 when the door 30 is closed. The pulley 85 is rotatably supported by the housing body 10 so as to rotate forward and backward coaxially and integrally with the body side clutch member 83. The link wire 87 is connected between the adjacent pulleys 85 so as to transmit a driving force. That is, the link wire 87 transmits the rotation of one main body side clutch member 83 to the other main body side clutch member 83 via the pulley 85.

The door-side clutch member 81 is substantially disk-shaped (or columnar), and has teeth (claws) radially formed from the rotation center axis in a plane including the rotation center axis. The body-side clutch member 83 is formed radially from the rotation center axis in a plane including the rotation center axis, and includes teeth (claws) that mesh with the respective teeth of the door-side clutch member 81.
The link wire 87 mutually transmits the driving force between the plurality of main body side clutch members 83. The tension and tensioning direction of the link wire 87 are appropriately adjusted by guide means, auxiliary pulleys, and the like arranged at appropriate places on the housing body 10 as necessary. Further, a plurality of link wires 87 are prepared as needed. For example, the pulley 85 and the link wire 87 can have the same configuration as in the first embodiment. That is, a plurality of endless link wires 87 are prepared, one endless link wire 87 is wound around two adjacent pulleys 85, 85, and a proper position of the link wire 87 is set in the pulleys 85, 85. Can be fixed.

<Meshing clutch>
The body-side clutch member 83 and the door-side clutch member 81 constitute a meshing clutch (dog clutch).
When the door 30 is open, the door-side clutch member 81 and the main-body-side clutch member 83 are in a disconnected state, but when the door 30 is closed, the paired door-side clutch member 81 and main-body-side clutch member A connection state is established in which the respective teeth of 83 are meshed. When the teeth of both clutch members 81 and 83 are engaged, power can be transmitted from door-side clutch member 81 to body-side clutch member 83 or in the opposite direction.
For example, with the doors 30a to 30d closed and the door-side clutch member 81 of each of the doors 30a to 30d engaged with the corresponding body-side clutch member 83, the lock piece 53 of one cylinder lock 50a is moved from the unlocked position. It is displaced to the locking posture (the direction of arrow A1). The driving force for actuating the lock piece 53 is transmitted from the door-side clutch member 81 to the main-body-side clutch member 83, and transmitted to all other main-body-side clutch members 83 connected to the link wire 87 via the link wire 87.
