Description

  The present invention relates to an electronic device storage rack (hereinafter simply referred to as “rack”) for storing electronic devices such as router devices and switch devices in a slidable manner.

As a rack for storing an electronic device so as to be slidable back and forth, for example, a rack disclosed in Patent Document 1 is known. This is because of the pair of guide rails horizontally mounted between the left and right support columns and the right and left support columns among the front and rear and left and right support columns of the rack. The moving rail is mounted so that it can slide back and forth.

In such a rack, a plurality of types of devices such as a router device, a switch device, and a server device may be stored at the same time. However, recent server devices are becoming deeper as the functions thereof are increased. On the other hand, since the depth of the router device and the switch device is generally shorter than that of the server device, the following problems arise.

JP 2001-144462 A

As shown in FIG. 18, in the situation where the server devices 2 and 3 having a long depth are stored above and below the router device 1, the cable attachment and detachment work to the connector provided on the rear surface of the router device 1 is performed. When performing, it is necessary to slide the router device 1 backward to a position where the rear surface coincides with at least the rear surfaces of the server devices 2 and 3.

However, since the interval between the server devices 2 and 3 is only about the height of the router device 1 (4.45 cm for a normal 1U size), the router is inserted between the server devices 2 and 3 It is difficult to grasp the device 1 and slide it backward.

Therefore, an object of the present invention is to provide a rack that can be easily slid to the rear side even in an electronic device such as a router device having a short depth.

This rack has a moving member supported so as to be slidable with respect to the guide rail, and is a rack for slidably storing a device attached to the moving member, wherein the moving member is attached to the device. The apparatus has a device drawer assisting tool that can be extended in the moving direction of the member main body and can be stored in the moving member main body.

Even a device with a short depth can be easily slid.

When releasing the fixed state and storing the gripping rod 14b in the movable rail body 14a, as shown in FIG. 9, the gripping rod 14b is once moved backward (arrow a) and the shaft 39 is moved. It may be slid forward (arrow c) while turning upwards around the center (arrow b).

As shown in FIG. 6, the moving rail 14 is in a state of being fitted between the upper and lower flanges 19, 21 of the guide rail 13, and more specifically in a state of being mounted on the lower flange, Is slidable.

The electronic device 11 is accommodated in the rack 12 by the slide rail 10 as follows.

First, as shown in FIG. 8, the pair of left and right moving rails 14 are fixed to the left and right side surfaces of the casing of the electronic device 11. This fixing is performed by inserting a screw 27 through the screw hole 48 of the movable rail body 14a. A cable support 49 (FIGS. 1, 2, 4, and 5) for supporting a cable connected to the rear surface of the electronic device 11 is provided between the rear ends of the pair of moving rail bodies 14a fixed to the electronic device 11. Is mounted horizontally and fixed by screws or the like.

Subsequently, the electronic device 11 is supported on the rack 12 by mounting the moving rail 14 on the lower flanges 19 and 21 of the guide rail 13 fixed to the rack 12 in advance.

  Then, as shown in FIG. 2, with the front surface of the electronic device 11 aligned with the front surfaces of the support columns 12a and 12b of the rack 12, the fixed plate 31 is bent 90 degrees outward with respect to the movable rail body 14a. It superposes | stacks on the fixed piece 15 of the front side guide rail 13a. By fastening the screw 27 inserted through the matching screw hole 29 and the fixing screw hole 38, the fixing of the electronic device 11 to the rack 12 is completed.

At this time, since the rear end of the gripping rod 14b is located in the vicinity of the support columns 12c and 12d on the rear surface side of the rack 12, as shown in FIG. 1, when pulling out the electronic device 11 to the rear surface side of the rack 12, Easy to grip.

When performing operations such as attaching and detaching cables to and from the rear surface of the electronic device 11 housed in the rack 12, first, the screw 27 of the fixing plate 31 is loosened to release the fixing state with respect to the guide rail 13, and the fixing plate 31 is rotated in a state parallel to the movable rail body 14a. Then, the gripping rod 14b is gripped by the rear end knob 44 and pulled out to the rear side of the moving rail body 14a to be extended, and further pulled backward, whereby the electronic device 11 is moved together with the moving rail body 14a to the rear surface of the rack 12. Slide to the side (Figure 4).

After the electronic device 11 is pulled out to the rear side, the extended gripping rod 14b can be stored in the movable rail body 14a as shown in FIG. As a result, the rear portion of the moving rail 14 (the gripping rod 14b) does not protrude greatly into the work space, so that workability is not impaired even when the cable is attached or detached in a narrow work space.

After the work, it is necessary to slide the electronic device 11 back to the state where the front surface of the electronic device 11 matches the front surface of the rack 12 (FIGS. 1 and 2).

  In this case, as shown in FIG. 4, the gripping rod 14b is extended backward again, and the notch 46 is engaged with the protrusion 40 (FIG. 10), thereby fixing the gripping rod 14b to the movable rail body 14a.

In this state, by pushing the knob 44 forward, the electronic device 11 can be easily slid to a position where the front surface of the electronic device 11 coincides with the front surface of the rack 12.

Therefore, when the electronic device 11 with a short depth is slid to the front side of the rack 12, even if there are devices with a long depth at the top and bottom of the electronic device 11, it is easy to insert the hand into the gap between them. You can slide.

At this time, even when the electronic device 11 is pushed too far to the front side, the protrusion 35 of the leaf spring 36 of the movable rail body 14a engages with the hole 30 of the front guide rail 13a. As a result, the electronic device 11 is prevented from slipping forward from the position shown in FIG.

If it is necessary to further pull out the electronic device 11 from the state of FIG. 3 to the front of the rack 12, the leaf spring 36 is pressed inward (on the electronic device 11 side) with an index finger to engage the projection 30 with the hole 30. The upper and lower surfaces of the electronic device 11 can be grasped and pulled out with other fingers while keeping the state released.

Example 2

Next, the rack according to the second embodiment having the slide rail 50 will be described with reference to FIGS.

The slide rail 50 according to the first embodiment is different from the slide rail 50 only in that a press-fit screw 53 is provided on a fixed plate 52 rotatably attached to the front end of the movable rail main body 51 without providing a fixing screw hole. Therefore, only the different points will be described and the other description will be omitted.

The press-fitting screw 53 has a spring (not shown) and a screw 54 built in a cylindrical body fixed to the fixing plate 52. Since the screw 54 is urged by the spring in the screw head direction, the tip of the screw 54 does not protrude from the back surface of the fixing plate 52 when not pressed in the screw tip direction (FIG. 14).

As shown in FIGS. 11 and 12, the fixed plate 52 is perpendicular to the moving rail body 51 and overlapped with the fixed piece 55 of the guide rail, and the tip of the fixed plate 52 is pressed while pressing the screw 54 in the screw tip direction. Is screwed into the screw hole 56 of the fixing piece 55, so that the electronic apparatus 11 can be fixed to the rack in the same manner as the slide rail 10 of the first embodiment.

When the moving rail is slid to the rear side of the rack, as shown in FIGS. 13 and 14, if the fixed plate 52 is in a state parallel to the moving rail body, the screw 54 is urged by a spring and the screw tip is fixed to the fixed plate. Since it does not protrude from 52, sliding is not hindered by the screw tip.

The slide rail 10 in the rack 12 according to the first embodiment requires a screw for fixing the moving rail 14 to the guide rail 13, and it is necessary to prepare another screw when the screw is lost.
On the other hand, since the slide rail 50 of the rack of the present embodiment includes the press-fit screw 53, it is not necessary to prepare a screw separately, and there is no possibility of losing the screw. Therefore, it is convenient when it is necessary to perform maintenance work by frequently sliding the electronic device 11 or when performing maintenance work by sequentially sliding a large number of electronic devices 11.

Example 3

Finally, the rack according to the third embodiment having the slide rail 60 will be described with reference to FIGS.

Unlike the electronic device 11 shown in the first and second embodiments, there is an electronic device 61 having a structure in which cables are connected to both the rear side and the front side (FIG. 15).
When such an electronic device 61 is slidably housed in a rack, the cable connected to the front side or the cable connected to the rear side must be routed to the other side. Depending on the length, there is a case where the slide cannot slide in any direction.

On the other hand, in order to route the cable to the other side, if the empty space is provided on the upper and lower sides of the electronic device 61 without storing other electronic devices, the device storage efficiency in the rack is deteriorated.
Therefore, the slide rail 60 of this embodiment is for a cable for inserting a cable on the side (inner surface side) facing the electronic device 61 by bending the side wall of the moving rail (moving rail main body) 62. The space 63 is formed over its entire length.
Through this cable space 63, a cable connected to one surface side of the electronic device 61 can be routed to the other surface side.
