Description

  The present invention relates to a rack capable of positioning a support rail used to support various devices on the rack frame, and more particularly to a rack that enables the support rail to be mounted on a rack frame of a different standard. .

  As a rack for mounting various electronic devices, a rack having a configuration in which a support rail is fixedly mounted on a rack frame and a device is mounted on the support rail is widely used. This is effective when the devices are mounted in the vertical direction. In a conventional rack, a plurality of pairs of support rails are mounted in advance on the left and right sides of the rack frame at predetermined vertical intervals, and the devices are mounted in the rack by supporting both sides of the device with a pair of support rails. The configuration is taken. In this case, since there is a possibility that the equipment with a large height cannot be mounted in the rack, the vertical distance between the support rails is set to a sufficient dimension, so when a device with a small height is mounted. A gap is generated between the upper and lower sides, and this gap is a waste of space in the rack. In particular, due to recent demands for miniaturization of racks, high density and high mounting, it is necessary to make maximum use of the limited space, and to minimize the vertical gap between mounting devices in the rack as much as possible. Is needed.

In response to such a demand, a rack has been proposed in which the mounting position of the support rail can be adjusted with respect to the rack frame in accordance with the height dimension of the apparatus to be mounted. For example, in the rack of Patent Document 1, a plurality of protrusions are provided on the mounting portion of the support rail (panel and shelf) of the rack frame (mounting angle), and through holes and notches are provided on the support rail side. A configuration is adopted in which the notch is fitted to the protrusion of the rack frame to adjust the mounting position of the support rail with respect to the rack frame. In the rack of Patent Document 1, by adjusting the vertical position of the support rail according to the height dimension of the device, the vertical gap between the mounted devices can be reduced as much as possible. It becomes possible to meet the demand for mounting.
Japanese Patent Laid-Open No. 10-137062

  In the rack of Patent Document 1, since the rack frame and the support rail are configured as a set in advance, other types of support rails are mounted on different types of rack frames having different standards for protrusions, through holes, and notches. May not be possible. For this reason, when various types of racks are to be deployed in accordance with the recent opening of various devices, it is necessary to use support rails corresponding to the rack frame to be equipped. In particular, in a normal rack, a plurality of support rails are attached to one rack frame. Therefore, when deploying various types of rack frames, various types of support rails corresponding to each type of rack frame are used. This must be prepared, which is not preferable in terms of cost and management. In addition to the above-mentioned protrusions and through hole and notch standards, there are similar problems when the rack depth is different, and there are many types of depth support rails corresponding to the rack frame depth. It is necessary to prepare.

  An object of the present invention is to provide a rack in which one support frame can be mounted on different types of rack frames. In particular, the present invention provides a rack that can be mounted on a rack frame having a different positioning structure standard for positioning a support frame on the rack frame or a rack frame having a different depth dimension.

  The present invention is a rack that includes a rack frame and a support rail for supporting a device that is fixedly mounted on the rack frame. The rack includes different types of rack frames for fixing portions that fix the support rail to the rack frame. It is characterized by comprising a plurality of positioning protrusions that can be respectively fitted into the provided positioning holes.

  According to the present invention, one support rail can be fixed to a rack frame having a different positioning hole or a rack frame having a different depth dimension, and the versatility of the support rail can be enhanced. This makes it possible to build a rack that eliminates the vertical space in the rack regardless of the type of rack frame, and to reduce the cost of the rack due to the versatility of the support rail. become.

  For example, in the rack of the present invention, the plurality of positioning protrusions are formed of two different protrusions, and one protrusion is formed in a size larger than the other protrusion and the protrusion height is lower than the other protrusion. When one projection fits into the positioning hole of one type of rack frame, the other projection is inserted into the positioning hole, and the other projection fits into the positioning hole of another type of rack frame. When mating, one of the protrusions is in contact with the fixed surface of the rack frame. Specifically, one of the protrusions is an angular protrusion that is close to a square, and the other protrusion is a circular protrusion having a diameter that is substantially equal to the length of one side of the angular protrusion. When positioning is performed using one or the other projection, the support rail can be fixed without the other or one projection interfering.

  Further, in the rack of the present invention, an adapter having a positioning projection that can be fitted in a positioning hole provided in a rack frame of a different type from the two different types of rack frames can be fixed to the fixing portion. To do. By fixing the adapter or by fixing another adapter, it becomes possible to fix the support rails to various types of rack frames, thereby enhancing versatility.

  In the present invention, the support rail is composed of a rail main body and an auxiliary rail movable in the length direction with respect to the rail main body, one end portion of the rail main body in the length direction, and opposite to the length direction of the auxiliary rail. A fixing portion is provided at each of the end portions on the side. The support rail can be applied to rack frames having different depth dimensions.

  The rail body includes a guide that is partially cut and raised, and the auxiliary rail is supported by the guide. The auxiliary rail is provided with a stopper for contacting the guide and preventing the auxiliary rail from falling off. The guide has a small protrusion that abuts against the surface of the auxiliary rail. This makes it possible to adjust the substantial length of the support rail by stably and reliably moving the auxiliary rail with respect to the rail body without using a separate member, reducing the number of parts and reducing costs. Can be realized.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view of a rack according to a first embodiment. A rack 1 according to the present invention includes a rack frame 2 and support rails 3 attached to the rack frame. The rack frame 2 is constructed by assembling a metal material or the like into a frame body. Here, the support pillars 21 erected on the front, rear, left and right sides are connected to the front and rear, left and right by the horizontal frames 22 at the upper and lower ends, respectively. is doing. In addition, a bottom plate, a top plate, and side plates are provided as needed to cover the inside of the rack frame, but these are not shown here. Each of the support columns 21 is formed of a stem having a substantially L-shaped horizontal cross section, and a large number of positioning holes 23 are opened at a predetermined pitch dimension in the vertical direction on the front or rear surface thereof in the front-rear direction. Has been. The positioning hole 23 is a square hole or a round hole depending on the type of the rack, that is, the rack frame 2, and the pitch dimension of the positioning hole 23 is common to each type of rack frame. In addition, the width dimension in the left-right direction and the depth dimension in the front-rear direction of the rack frame 2 are formed in arbitrary dimensions for each type of rack frame.

  As shown in FIG. 2, the support rail 3 includes a rail body 4 having a substantially rectangular plate shape elongated in the front-rear direction, and an auxiliary rail 5 slidably connected to the rail body 4 in the length direction. It is configured. The rail body 4 has a fixing flange 6 bent at one end at a substantially right angle, and fixed at the opposite end of the auxiliary rail 5 at a substantially right angle similarly to the fixing flange 6. A flange 7 is provided. Furthermore, it has a rail portion 8 that is bent at a right angle along the lower edge of the rail body 4 in the direction opposite to the fixed flanges 6 and 7. As shown in FIG. 1, the support rail 3 is configured so that the fixing flanges 6 and 7 of the rail body 4 and the auxiliary rail 5 are connected to the front side or the rear side of the rack frame 2 with the rail portion 8 facing inward. A pair of support rails 3 are fixed to the left and right of the same height position of the rack frame 2 by being fixed to the support pillars 21 of the rack frame 2 and mounted on each rail portion 8 of the support rails 3. The left and right lower edges are supported and the apparatus is mounted in the rack. That is, when the support rail of FIG. 2 is mounted on the left side toward the inside of the rack frame 2 shown in FIG. 1, the fixing flange 6 of the rail body 4 is fixed to the support pillar 21 on the front side of the rack frame 2 and the auxiliary rail. The fixing flange 7 is fixed to the rear support column. When the same support rail 3 is mounted on the right side in the rack frame 2, a support rail symmetrical to the support rail 3 in FIG. 2 is provided, and the support rail is mounted on the rack frame 2. In this case, it is possible to use the support rail 3 of FIG. 2, the fixing flange 6 of the rail body 4 is fixed to the rear supporting column 21, and the fixing flange 7 of the auxiliary rail 5 is fixed to the front supporting column 21. By fixing, it is possible to use the support rail 3 as either left or right support rail.

  The auxiliary rail 5 is formed in an elongated plate shape whose width dimension in the vertical direction is slightly smaller than that of the rail body 4. Then, as will be described in detail later, two pairs of guide pieces 41 are formed by cutting and raising two portions in the front-rear direction along the upper and lower edges of part of the rail body 4, and facing each other in the vertical direction. The auxiliary rail 5 is inserted into a region sandwiched by the guide pieces 41 so as to be movable in the length direction with respect to the rail body 4. A stopper 51 is integrally formed at one end of the auxiliary rail 5, and when the auxiliary rail 5 moves, the stopper 51 comes into contact with the guide piece 41 so that the auxiliary rail 5 is dropped from the rail body 4. Is prevented.

  FIG. 3 is an enlarged perspective view of the fixed flange 6 of the rail body 4 as viewed from the right. Since the fixing flange 7 of the auxiliary rail 5 has the same configuration as the fixing flange 6, only the fixing flange 6 will be described here. The fixing flange 6 is elongated in the vertical direction, and five angular protrusions 61a to 61e are integrally formed on the front surface so as to protrude in the vertical direction. In addition, two round protrusions 62a and 62b are integrally formed so as to protrude from an intermediate portion in the vertical direction where the corner protrusions 61a to 61e are not formed on the front surface of the fixed flange 6. The round protrusions 62a and 62b are circular with a required diameter dimension, and the angular protrusions 61a to 61e have a shape close to a square with substantially the same side dimension as the diameter of the round protrusions 62a and 62b. Further, the projections 61a to 61e have a small projection height, the round projections 62a and 62b have a projection height larger than the projections 61a to 61e, and the round projections 62a and 62b and the square projection 61 are vertically It is arranged at a required pitch dimension position in the direction or a dimension position that is a multiple thereof.

  Here, a slit 63 a is formed in the width direction of the fixed flange 6 at a position directly below the upper corner protrusion 61 a among the five corner protrusions. The third corner projection 61 c from the bottom is formed in a tongue piece 64 formed by cutting out a part of the fixing flange 6, and a slit 63 b is formed along the base portion of the tongue piece 64. These slits 63a and 63b are used when the angular projections 61a and 61c are separated from the fixed flange 6 as described later. Further, the lowermost corner projection 61e is configured to bend the lower end portion of the fixed flange 6 in the front direction and to process the bent portion into a square shape.

  In addition, device fixing screw holes 65a and 65b for fixing devices to be mounted are opened in the corner projections 61a and 61c provided with the slits 63a and 63b among the corner projections 61a to 61e. A rail fixing screw hole 66 for fixing the support rail 3 to the rack frame 2 is opened in the second corner projection 61d from the bottom. Furthermore, adapter fixing screw holes 67a and 67b for fixing an adapter, which will be described later, are opened at positions of the fixing flange 6 excluding the angular protrusion and the round protrusion.

  When the support rail 3 having the above configuration is mounted on the rack frame 2, as shown in FIG. 4, when the positioning hole formed in the support pillar 21 of the rack frame 2 is a square hole 23A, The front surface of the fixed flange 6 is brought into close contact with the inner surface of the support column 21, and the square protrusions 61a to 61e provided on the fixed flange 6 are fitted into the square holes 23A to perform vertical and horizontal positioning. At this time, since the round projections 62a and 62b are smaller in size than the square projections 61a to 61e, the round projections 62a and 62b are inserted into the square holes 23A. Then, the fixing flange 6, that is, the support rail 3 can be fixed to the rack frame 2 by screwing the rail fixing screw 11 into the rail fixing screw hole 66 through the square hole 23 </ b> A from the outside of the rack frame 2.

  The same applies to the fixing flange 7 provided on the auxiliary rail 5 on the opposite side of the support rail 3. At this time, the auxiliary rail 5 is moved with respect to the rail body 4 so that the front surface of the fixing flange 7 is brought into close contact with the support pillar on the rear side of the rack frame 2, and the square protrusions are fitted into the square holes as in the front side. , It is fixed to the support column with rail fixing screws.

  The same applies to the support rails fixed to the right side of the rack frame 2, so that the rail portions 8 of the pair of support rails 3 fixed so as to oppose in the left-right direction face each other. Then, as shown in FIG. 5, the apparatus 100 is inserted into the rack frame 2 so that the left and right lower edges of the apparatus 100 are placed on these rail portions 8, and the front panel 101 of the apparatus 100 is inserted. The device fixing screw 12 through which the fixing screw hole 102 is inserted is inserted into the square hole 23A of the rack frame 2 and further screwed into the device fixing screw holes 65a and 65b provided in the fixing flange 6. 100 can be fixed to the rack frame 2 and can be mounted on the rack 1.

  On the other hand, as shown in FIG. 6, when the positioning hole formed in the support column 21 of the rack frame 2 is a round hole 23 </ b> B, the front surface of the fixing flange 6 of the support rail 3 is brought into close contact with the inner surface of the support column 21. At the same time, the round protrusions 62a and 62b provided on the fixed flange 6 are fitted into the round holes 23B to perform positioning in the vertical direction and the horizontal direction. At this time, since the corner projections 61a to 61e are larger in size than the round projections 62a and 62b, the corner projections 61a to 61e are not inserted into the round hole 23B but are brought into contact with the inner surface of the support column 21. Then, the support rail 3 can be fixed to the rack frame 2 by screwing the rail fixing screw 11 from the outside of the rack frame 2 into the rail fixing screw hole 66 through the round hole 23B. Also in this case, the fixing flange 7 is fixed to the rear support column 21 after adjusting the protruding length of the auxiliary rail 5 on the rear side of the rack frame 2. Similarly, the apparatus 100 can be mounted on the rack 1 as shown in FIG.

  In this embodiment, the round projections 62a and 62b are formed in a smaller size than the square projections 61a to 61e, but conversely, the square projections 61a to 61e may be made smaller than the round projections 62a and 62b. When configured in this way, the projections of the corner projections are made higher than the round projections, and when the rack frame is a round hole, the corner projections are inserted into the round holes, and when the rack frame is a square hole, the round projections are supported. What is necessary is just to comprise so that it may contact | abut to the inner surface of a pillar.

  Furthermore, as shown in FIG. 7, when the positioning hole 23 provided in the support column 21 of the rack frame 2 is not a round hole or a square hole, but is a small diameter hole 23C in which a round projection or a square projection cannot be fitted. The adapter 9 provided separately is used. The adapter 9 has small-diameter projections 91a and 91b that can be fitted in the small-diameter hole 23C on the front surface, and the adapter fixing screw 13 that passes through the adapter fixing holes 92a and 92b is connected to the adapter fixing screw hole 67a of the fixing flange 6. It is integrally fixed to the front surface of the fixing flange 6 by being screwed to 67b. The adapter 9 has relief holes 93a to 93d for receiving the round protrusions 62a and 62b and for inserting the device fixing screws 12 screwed into the fixing screw holes 65b and 66, respectively. Therefore, when the adapter 9 is fixed, the small-diameter protrusions 91a and 91b are fitted into the small-diameter holes 23C of the support column 21, and the rail fixing screw 11 is fixed in the same manner as shown in FIG. 4 or FIG. The support rail 3 can be fixed to the rack frame 2 by being screwed into the rail fixing screw hole 66 of the flange 6.

  By fixing the adapter 9 having the projections of different standards to the fixing flanges 6 and 7 of the support rail 3 as described above, the support rail of the first embodiment is mounted on the rack frame 2 having positioning holes of all standards. can do. Further, by moving the auxiliary rail 5 and adjusting the substantial length of the support rail 3, the support rail of the first embodiment can be mounted on the rack frame 2 having different depth dimensions.

  Here, the support rail according to the first embodiment includes device fixing screw holes 65a and 65b for fixing the device to the fixing flange 6. However, depending on the type of the device, the device is configured to fix the device to the rack frame 2. In this case, the fixing flange 6 does not require the device fixing screw holes 65a and 65b. At this time, the device fixing screw holes may be left as they are, but the uppermost angular protrusion 61a shown in FIG. 3 provided with the device fixing screw holes 65a and 65b and the bottom 3 provided on the tongue piece 64 are provided. The second angular protrusion 61c can be removed by separating it from the fixed flange 6 using slits 63a and 63b provided in the fixed flange 6.

  In the configuration of the first embodiment as the configuration of the guide piece 41 that movably supports the auxiliary rail 5 on the rail body 4, the upper and lower edges of the rail body 4 are shown in detail in FIG. 2 are cut and raised in a U shape so as to face each other, and are bent and raised in an L shape so as to form a gap through which the auxiliary rail 5 can be inserted between the outer surface of the rail body 4. The auxiliary rail 5 can be moved in the length direction of the rail body 4 while the upper edge and the lower edge are respectively guided by the upper and lower guide pieces 41. Instead of this configuration, as shown in FIG. 8B, a guide piece 41A is formed that cuts and raises a region extending from the vicinity of the upper edge to the vicinity of the lower edge of the rail body 4 to form a gap through which the auxiliary rail 5 can be inserted. May be.

  On the other hand, in order to prevent the auxiliary rail 5 from falling off the rail body 4, in the first embodiment, the stopper 51 is provided at one end of the auxiliary rail 5, as shown in FIG. 9 (a). A tongue piece is formed on one end edge of the auxiliary rail 5, and the tongue piece is bent at a substantially right angle. Alternatively, as shown in FIG. 9B, a part of one end edge of the auxiliary rail 5 may be cut and raised in a trapezoidal shape to form the stopper 51A. Furthermore, as shown in FIG. 9C, a minute protrusion may be formed as the stopper 51B. In any case, when the support rail 3 is assembled, it is necessary to insert the auxiliary rail 5 between the guide pieces 41 and 41A of the rail body 4 from one end side, and to process the stopper after the insertion, as shown in FIG. In the case of a) and (b), these portions are bent after the auxiliary rail 5 is inserted, and in the case of FIG. 9C, the window 43 provided in the rail body 4 is used after being inserted. A part of the auxiliary rail 5 is driven out to form a protrusion. As described above, the stoppers 51, 51A, 51B come into contact with the guide pieces 41, 41A during movement to prevent the auxiliary rail 5 from falling off.

  In this way, when configuring the support rail of Example 1 having a fixed flange, an auxiliary rail, etc., separate members such as screws and rivets are completely unnecessary, reducing the number of parts and reducing the cost. This is advantageous for achieving the above.

  In the first embodiment, as shown in FIG. 2, a minute protrusion 42 in which a part of the guide piece 41 is driven out toward the inner surface is provided so that the auxiliary rail 5 does not move relative to the rail body 4. Yes. When the minute protrusions 42 abut against the outer surface of the auxiliary rail 5, some resistance is given to the movement of the auxiliary rail 5, moderation is given to the movement position of the auxiliary rail 5, and the support rail 3 is attached to the rack frame 2. The workability at the time can be improved.

  In the first embodiment, an example in which five angular protrusions and two round protrusions are provided on the fixed flange is shown, but it is sufficient that at least one protrusion is provided. However, in order to perform stable positioning, it is preferable to provide two or more at a required interval in the vertical direction. Further, the different types of protrusions are not limited to the square protrusions and round protrusions of the first embodiment, and it is needless to say that the protrusions can be appropriately changed according to the shape of the positioning hole provided in the rack frame.
