The present invention relates to a rack system, an adapter, a rack frame, a support rail, and a method for manufacturing the rack system, which can place a support rail used to support various devices in a rack frame. will be. More specifically, the present invention relates to a rack in which a support rail can be mounted on a rack frame having another specification.

As racks for mounting various types of electronic devices, racks having support rails fixedly attached to the rack frame are widely used, and devices are mounted on the support rails. This type of rack is particularly useful when multiple devices are mounted in a vertical arrangement.

In a conventional rack, a plurality of pairs of support rails are pre-attached to the right and left sides of the rack frame at predetermined vertical intervals, and both sides of the device are each supported by a pair of support rails, whereby the device is mounted in the rack. However, in this case, devices with large heights may not be mounted in the rack. Therefore, the rack should be constructed so that the vertical spacing of the support rails is of sufficient size. However, when a device having a small height is mounted, there is a gap in the vertical gap, which is a waste of space in the rack. In particular, there is a need to utilize limited space as much as possible according to the recent demand for mounting in a small rack size and high density, and to minimize the vertical gap between the devices mounted in the rack.

To meet this need, racks have been provided in which the attachment position of the support rail can be adjusted relative to the rack frame according to the height of the device to be mounted. For example, in the rack shown in Japanese Patent Laid-Open No. 10-137062, a plurality of projections are provided at the attachment site of the rack frame (mounting angle) and the support rail (panel and shelf), and through holes and notches. ) Is installed on the support rail side. By fitting these through holes and notches around the projections of the rack frame, positioning is performed while adjusting the attachment position of the support rail to the rack frame. In the rack of Japanese Patent Laid-Open No. 10-137062, by adjusting the vertical position of the support rail according to the height of the device, the vertical gap between the mounted devices can be minimized, and the demand for small rack size and high density mounting is eliminated. Can satisfy.

However, in Japanese Patent Laid-Open No. 10-137062, since the rack frame and the support rail are pre-structured as a set (for example, an assembly), one kind of support rail of the rack frame has a different specification with respect to protrusions and through holes. It may not be attached to any kind of rack frame. Thus, if a variety of racks is provided for various types of devices as a result of recent "open design" (for example, designs that can be used extensively for many types of devices), the rack frame is equipped. Supporting rails shall be used. In particular, in ordinary racks, multiple support rails are used in one rack frame. Therefore, when many kinds of rack frames are installed, many kinds of support rails should be prepared for each kind of rack frames. This is undesirable in terms of cost as well as control (eg management). In addition to the specifications for the projections, through-holes and notches described above, the same problem arises when the racks have different depth dimensions, and it is necessary to prepare support rails having many kinds of depth dimensions suitable for the depth dimensions of the rack frame.

In view of the other exemplary problems, drawbacks, and disadvantages of the prior art described above, an exemplary feature of the invention is that a rack system, a rack frame, a support rail, and one support frame (eg, a support rail) may be of different types. Provided is a method of manufacturing a rack system that can be mounted on a rack frame. In particular, for example, the present invention mounts the support frame to a rack frame having a different specification (e.g., a positioning structure) relative to the structure for positioning the support frame to a rack frame or a rack frame having other depth dimensions. It is to provide a rack that can.

The present invention provides a rack system comprising a rack frame and a support rail fixed to the rack frame. The device can be supported by a support rail. A plurality of positioning protrusions including a first positioning protrusion and a second positioning protrusion are installed on any one of the rack frame and the supporting rail, and the first positioning protrusion and the second positioning protrusion are arranged on the rack. It is inserted or fitted into the positioning holes respectively installed in the other one of the frame and the support rail.

According to the invention, for example, one support rail can be fixed to a rack frame having different positioning holes and to a rack frame having different depth dimensions, thereby improving the versatility of the support rail. Also, for example, one rack frame can be fixed to a support rail having another positioning hole. As a result, by preparing only one support rail or one rack frame, a rack can be constructed that eliminates wasted vertical space in the rack regardless of the type of the rack frame or the type of the support rail, while at the same time reducing the cost of the rack. It can reduce by using a lot of support rails or a rack frame.

1 is a schematic perspective view of an embodiment rack 1, in which the rack 1 according to the invention comprises, as an example, a rack frame 2 and a support rail 3 attached to the rack frame 2.

The rack frame 2 may be a frame body assembled from a metal material or the like. In this case, the supporting posts 21 can be installed back and front, respectively, in an upright position (e.g. vertically), so that the right and left supports 21 are respectively back and front thereof. The right and left sides of the upper and lower ends are connected by the side frame members 22 to form a frame body. Bottom plates, top plates, and side plates (not shown) may cover the interior of the rack frame as needed. For example, each support 21 may be formed in the front and rear of the support from a pillar having an approximately L-shaped horizontal cross section, and the plurality of positioning holes 23 may be provided with a predetermined vertical pitch size. Together with the opening in the front and rear direction. The positioning holes 23 may be formed as angled holes or round holes depending on the type of the rack (for example, the rack frame 2). However, for example, the pitch size of the positioning holes 23 can be common in various kinds of rack frames. The width dimension of the rack frame 2 in the left-right direction and the depth dimension in the front-back direction are arbitrarily chosen with respect to various rack frames.

As shown in FIG. 2, the support rail 3 includes a rail body 4, which can be an enlongated plate of approximately rectangular shape in the front-rear direction, and a rail body 4 so as to be slidable in the longitudinal direction. It may comprise an auxiliary rail (5) which can be connected to. The rail body 4 may have a fixing flange 6 at one end thereof, which is formed to be bent at almost right angles, and at the end of the auxiliary rail 5 at the opposite side, the fixing flange 6 Together with a fixing flange 7 which is formed to warp at approximately right angles. The rail body 4 can also have a rail section 8, which can be formed in bending at right angles in the opposite direction to the fixing flanges 6, 7, along its lower rim.

As shown in FIG. 1, such support rails 3 are provided with respective fixing flanges 6 and 7 of the rail body 4 and the auxiliary rails 5 to the support 21 at the front side or the rear side of the rack frame 2. ) Together with the rail section 8 facing inward, whereby the pair of support rails 3 are fixed on the same height position of the rack frame 2 opposite the right and left sides and mounted The right and left lower edges of the device are supported by respective rail sections 8 of the support rail 3 so that the device is mounted in a rack.

For example, in attaching the support rail of FIG. 2 to the left side of the observer inside the rack frame 2 shown in FIG. 1, the fixing flange 6 of the rail body 4 is located on the front side of the rack frame 2. It is fixed to the support 21 and the fixing flange 7 of the auxiliary rail 5 is fixed to the support at the rear side.

In addition, in attaching the same support rail 3 to the right side inside the rack frame 2, a symmetrical support rail is installed on the support rail 3 of FIG. 2 and the support rail is attached to the rack frame 2. do. In this case, the supporting rail 3 of FIG. 2 can be used, which fixes the fixing flange 6 of the rail body 4 to the support 21 at the rear side and the fixing flange 7 of the auxiliary rail 5. By fixing it to the support 21 at the front side, the support rail 3 can be used as either the right and left support rails.

The auxiliary rail 5 can be formed as an extension plate with a vertical width dimension that is somewhat smaller than the rail body 4. As in the following detailed description, a portion of the rail body 4, in this case, two plates in the front-rear direction along the vertical rim, can be cut off to form raised portions, respectively. . In this way, two pairs of guide points 41 that can be perpendicularly opposed to each other can be formed. The auxiliary rail 5 can be inserted into the area between these guide points 41 and can move in the longitudinal direction of the rail main body 4. In addition, the stopper 51 can be integrally formed at one end of the auxiliary rail 5, so that the stopper 51 is in contact with the guide portion 41 during the movement of the auxiliary rail 5.

3 is an enlarged perspective view of an exemplary fixing flange 6 of the rail body 4 seen from the right side of the viewer. In addition, since the fixing flange 7 of the auxiliary rail 5 can have a structure substantially the same as the fixing flange 6, only the fixing flange 6 is demonstrated here. The fixing flange 6 may be formed to extend vertically and at the front thereof, and the fixing flange 6 may include a plurality of positioning protrusions. For example, the five angled protrusions 61a to 61e may be integrally formed vertically.

Further, two rounded projections 62a and 62b are integrally formed at the central portion of the front face of the fixing flange 6 in the vertical direction in which the angled projections 61a to 61e are not formed. The round protrusions 62a and 62b are circular having the required diameter dimensions, and the angled protrusions 61a to 61e may be, for example, almost squares having side diameters substantially equal to the diameters of the round protrusions 62a and 62b. .

Further, the protruding height of the angled protrusions 61a to 61e is small, and the protruding height of the rounded protrusions 62a and 62b is larger than the angled protrusions 61a to 61e. Further, the round protrusions 62a and 62b and the angled protrusions 61a to 61e are disposed at positions having a required vertical pitch or positions having a size that is a multiple of this pitch size.

A slit 63a can be formed in the width direction of the fixing flange 6 just below the angled protrusion 61a at the upper end of the five angled protrusions 61a to 61e. The angled projection 61c, which is third from the bottom, may be formed in the tongue 64 formed by notching a part of the fixing flange 6. The slit 63a may be formed along the base portion of the tongue 64. These slits 63a and 63b are used when the angled protrusions 61a and 61c are separated from the fixing flange 6, as described below. Further, the angular projection 61e at the lowest lower portion is formed by bending the lower end of the fixing flange 6 upward and can operate as a bent up portion in an angular form.

The device fixing screw holes 65a and 65b for fixing the mounted device can be opened in the angled protrusions 61a and 61c provided with the slits 63a and 63b among the angled protrusions 61a to 61e. Further, the rail fixing screw hole 66 for fixing the support rail 3 to the rack frame 2 can be opened in the angled protrusion 61d which is second from the bottom. In addition, the adapter fixing screw holes 67a and 67b for fixing the adapter described below can be formed at positions other than those of the angled protrusion and the round protrusion of the fixing flange 6.

In attaching the exemplary support rail 3 of the above-described structure to the exemplary rack frame 2, as shown in FIG. 4, the positioning hole formed in the support 21 of the rack frame 2 is an angled hole. 23A, the front surface of the fixing flange 6 of the support rail 3 is brought close to the inner surface of the support 21, and the angled protrusions 61a to 61e provided on the fixing flange 6 are angled holes. It fits in 23A. At this time, for example, the round protrusions 62a and 62b (eg, the lower protrusions 61a to 61e) having a smaller size than the angled protrusions 61a to 61e are wider than the high protrusions 62a and 62b. Is inserted into the angled hole 23A. Thereafter, the rail fixing screw 11 penetrates through the angled hole 23A from the outside of the rack frame 2 into the rail fixing screw hole 66, whereby the fixing flange 6 (for example, the support rail ( 3)) to the rack frame (2).

This can also be applied, for example, to the fixing flange 7 installed on the auxiliary rail 5 on the opposite side to the supporting rail 3. At this time, the auxiliary rail (5) moves relative to the rail body (4) and the front of the fixing flange (7) is close to the support of the rear of the rack frame (2), the angled projection is angled in the same way in the front case Fitted into a binary hole, the fixing flange 7 is fixed to the support by rail fixing screws.

The same can also be applied for the support rail 3 fixed to the right side of the rack frame 2, for example. As a result, in the pair of supporting rails 3 fixed to face horizontally, the rail sections 8 are opposed to each other.

Thereafter, as shown in FIG. 5, the device 100 is inserted into the rack frame 2 so that the right and left lower edges of the device 100 lie in the rail compartment 8. The device fixing screw 12 inserted into the fixing screw hole 102 installed in the front panel 101 of the device 100 is inserted into the angled hole 23A of the rack frame 2 and installed in the fixing flange 6. Further penetrates into the device fixing screw holes 65a and 65b. Therefore, the device 100 is fixed to the rack frame 2 and the device 100 is mounted to the rack 1.

On the other hand, as shown in FIG. 6, when the positioning hole formed in the support stand 21 of the rack frame 2 is round hole 23B, the front of the fixing flange 6 of the support rail 3, for example. Is close to the inner surface of the support 21 (eg, the fixed surface 26). In addition, the round projections 62a and 62b provided on the fixing flange 6 are fitted into the round holes 23B, whereby positioning in the vertical and horizontal directions is performed.

At this time, for example, the angled protrusions 61a to 61e having a larger size than the round protrusions 62a and 62b are in contact with the inner surface of the support 21 (for example, the fixed surface 26), It is not inserted into the round hole 23B. Thereafter, the rail fixing screw 11 penetrates into the rail fixing screw hole 66 from the outside of the rack frame 2 through the angled hole 23B. Therefore, the support rail 3 is fixed to the rack frame 2. Also in this case, at the rear of the rack frame 2, the fixing flange 7 is fixed to the rear support 21 after adjustment of the protruding length of the auxiliary rail 5. Also, as shown in FIG. 5, on the opposite side horizontally, the device 100 can be mounted to the rack 1 by fixing the support rails 3.

In the present embodiment, the rounded projections 62a and 62b are formed in a smaller size than the angled projections 61a to 61e. However, the angled protrusions 61a to 61e may be formed in a smaller size than the round protrusions 62a and 62b. In the case of the latter structure, the protrusion height of the angled protrusion is larger than that of the round protrusion. If the rack frame has a round hole, the round protrusion and the angled synchronous are structured such that the angled protrusion is inserted into the round hole, whereas if the rack frame has the angled hole, the round protrusion comes into contact with the inner surface of the support. .

Next, as shown in FIG. 7, the fixing portion (for example, the fixing flanges 6, 7, or 6a: 6a will be described later) may include a rack frame 2 and a rack frame 2 that are different from the supporting rails. 3) an exemplary adapter having positioning projections fitted in the positioning holes 23C provided in any one of (for example, the positioning holes 23C in the rack frame 2 are shown in this embodiment). It can be fixed with (9), the support rail 3 (for example, different from the rack frame 2 shown in the present embodiment) will be described later.

As shown in FIG. 7, the positioning projections provided on either the rack frame 2 or the support rail 3 can be fitted to the positioning holes provided on either the rack frame 2 or the support rail 3. If none, or can be inserted, the adapter 9 can be used. For example, when the positioning hole 23 provided in the support 21 of the rack frame 2 is a small diameter hole 23C to which the round protrusion and the angled protrusion can fit, and the round hole is neither the angled hole nor the round hole 23C. Alternatively, an adapter 9 separately installed can be used.

In the exemplary adapter 9, small diameter protrusions 91a and 91b, which can be fitted into the small diameter holes 23C, are formed in the front face. By passing the adapter fixing screw 13 penetrating through the adapter fixing holes 92a and 92b into the adapter fixing screw holes 67a and 67b of the fixing flange 6, the adapter 9 is connected to the front side of the fixing flange 6. It is fixed integrally to. In the adapter 9, clearance holes 93a to 93d for accommodating the round projections 62a and 62b and for inserting the device fixing screws 12 penetrated into the above-mentioned fixing screw holes 65b and 66, respectively. Is opened. Therefore, when the adapter 9 is fixed, the small diameter projections 91a and 91b are fitted into the small diameter holes 23C of the support 21. Then, as shown in FIG. 4 or 6, the rail fixing screw 11 penetrates into the rail fixing screw hole 66 of the fixing flange 6 in the same manner so that the supporting rail 3 is supported by the rack frame 2. Fix it to

For example, by fixing the adapter 9 having projections of different specifications to the fixing flanges 6 and 7 of the supporting rail 3, the supporting rail of the embodiment has a rack frame having positioning holes of any kind of specification. It may be possible to attach to (2). In addition, by adjusting the sufficient length of the support rail 3 by moving the auxiliary rail 5, it is possible to attach the support rail of the embodiment to the rack frame 2 having another depth dimension.

The support rail of the embodiment has device fixing screw holes 65a and 65b for fixing the device to the fixing flange 6. However, depending on the type of device, the device is fixed to the rack frame 2, in which case the device fixing screw holes 65a, 65b are not necessary for the fixing flange 6. Therefore, although the device fixing screw hole can be left on its own, it is provided in the angled projection 61a and the tongue 64 at the highest position where the device fixing screw holes 65a, 65b, shown in FIG. The angled projection 61c from the third from below can be separated and removed from the fixing flange 6 using the slits 63a and 63b provided on the fixing flange 6.

Moreover, in the structure of the Example which includes the guide part 41 which supports the auxiliary rail 5 so that the rail main body 4 can move, as shown in detail in FIG.8 (a), of the rail main body 4 The portion near the upper rim and the lower rim may be cut to form a U-shaped (eg, U-shaped) tongue so as to face each other and bent into an L-shape, so that a gap into which the auxiliary rail 5 is inserted Is formed between the auxiliary rail 5 and the outer surface of the rail body 4. The auxiliary rail 5 can move in the longitudinal direction of the rail main body 4, and guides an upper edge and a lower edge by the upper and lower guide points 41, respectively.

In general, as shown in FIG. 8B, the area from the upper edge vicinity to the lower edge of the rail body 4 has a guide point 41A having a gap into which the auxiliary rail 5 can be inserted. It can be cut so as to form the tongue.

On the other hand, in order to prevent the auxiliary rail 5 from falling off from the rail main body 4, in the embodiment, for example, a stopper 51 may be provided at one end of the auxiliary rail 5. As shown in Fig. 9 (a), it may be a tongue formed at one end edge of the auxiliary rail 5, and this tongue may be bent upward at an almost right angle.

In addition, as shown in Fig. 9B, a part of one end edge of the auxiliary rail 5 can be cut to form a trapezoidal standing portion with the stopper 51A. In addition, as shown in Fig. 9C, the minute protrusions can be formed as the stopper 51B.

In some cases, in assembling the support rail 3, the auxiliary rail 5 is inserted from one end side through the guide points 41 and 41A of the rail main body 4, and installs a stopper after insertion. In the case of FIGS. 9A and 9B, these parts can bend after insertion of the auxiliary rail 5 and in FIG. 9C, after insertion, a portion of the auxiliary rail 5 is The window 43 provided in the rail body 4 may be used to form a projection. As described above, the stoppers 51, 51A, 51B come into contact with the guide points 41, 41A during movement, thereby preventing the auxiliary rail 5 from falling off.

As a result, for example, in constructing the supporting rail of the embodiment provided with the fixing flange, the auxiliary rail, and the like, a separating member such as a screw and a rivet is not necessary. This is desirable to reduce the number of components and to reduce the associated costs.

In addition, in the embodiment, as shown in FIG. 2, a part of the guide portion 41 is beaten toward the inner surface by the minute protrusion 42 so that the auxiliary rail 5 does not move excessively with respect to the rail body 4. do. By contacting the micro-projections 42 with the outer surface of the auxiliary rail 5, the movement of the auxiliary rail 5 is counteracted to some extent, and the movement position of the auxiliary rail 5 is appropriate, whereby the supporting rail ( When 3) is attached to the rack frame (2) increases workability.

In the above-described embodiment, five angled protrusions and two rounded protrusions are installed on the fixing flange, but at least one of the protrusions may be installed by various protrusions. However, in order to perform stable positioning, it is preferable to provide two or more projections vertically at a necessary interval. In addition, other kinds of projections are not limited to the angled projections and the round projections of the embodiment. Therefore, the projection can be appropriately changed in accordance with the shape of the positioning hole provided in the rack frame.

In an embodiment, it is possible to support a device 100 on which a plurality of positioning protrusions 61, 62 are mounted, which can be fitted into different positioning holes 23A, 23B of different types of rack frames 2, respectively. It is installed in the support rail (3). Next, an example of many positioning protrusions provided in the rack frame 2 is demonstrated.

10 shows an exemplary perspective view showing a method of securing to a rack frame 2 having a plurality of positioning protrusions 24A, 24B. In the present embodiment, the rack frame 2 includes a plurality of positioning protrusions which can each fit into different positioning holes of different kinds of support rails 3. The angled protrusions 24A and the rounded protrusions 24B are installed in the fixing portion 6a of the rack frame 20, and the angled protrusions 24A are inserted into the angled holes 68A provided in the support rail 3. Can be adjusted. The round protrusion 24B can be inserted into the angled hole 68A. As shown in the embodiment, by simply preparing one type of rack frame, the rack is structured to eliminate vertical space consumed in the rack regardless of the type of the support rail 30.
