Description
- 1. Technical Field
- The present invention relates to a rack system which can position support rails used to support various devices on rack frames, an adapter, a rack frame, a support rail, and a method of making a rack system. More particularly, the present invention relates to a rack which enables support rails to be mounted on rack frames having different specifications.
- 2. Background
- As a rack to mount various types of electronic devices, there is widely used a rack having support rails that are attached to rack frames in a fixed manner and devices are mounted on the support rails. This type of rack is useful especially in a case where multiple devices are mounted in a vertical array.
- In conventional racks, multiple pairs of support rails are attached beforehand to the right and left sides of a rack frame at prescribed vertical intervals and both sides of a device are each supported by a pair of support rails, whereby the device is mounted within the rack. However, in this case, a device having a large height may not be capable of being mounted within the rack. Therefore, the rack must be constructed so that the vertical intervals of the support rails have a sufficient size. However, when a device having a small height is mounted, gaps are produced in the vertical intervals, thereby wasting space in the rack. In particular, it has become necessary to utilize a limited space to a maximum degree owing to recent requirements for smaller rack size and higher density mounting, and it has become necessary to minimize the vertical gaps between mounted devices in the rack.
- To meet such requirements, racks have been proposed in which attaching positions of the support rails can be adjusted with respect to rack frames according to the height of the devices to be mounted. For example, in a rack disclosed in Japanese Patent Laid-Open No. 10-137062, multiple projections are provided in the attaching portions of rack frames (mount angles) and support rails (panels and shelves), and through holes and notches are provided on the support rail side. By fitting these through holes and notches around the projections of the rack frames, positioning is performed while adjusting the attaching positions of the support rails with respect to the rack frames. In the rack of Japanese Patent Laid-Open No. 10-137062, by adjusting the vertical positions of the support rails according to the height of the devices, the vertical gaps between the mounted devices can be minimized and the requirements for smaller rack size and higher density mounting may be met.
- However, because in the rack of Japanese Patent Laid-Open No. 10-137062, the rack frames and support rails are constructed beforehand as sets (e.g., assemblies), support rails of one kind of rack frame may not be attachable to different kinds of rack frames having different specifications for projections and through holes. Hence, when a variety of racks are provided for the various kinds of devices which is a result of recent “open design” (e.g., a design which can be generically used for many kinds of devices), support rails must be used which are suited to the rack frames to be furnished. In particular, in a usual rack, multiple support rails are used for one rack frame. Therefore, when many kinds of rack frames are provided, many kinds of support rails must be prepared suited to each kind of rack frame. This is undesirable in terms of control (e.g., management) as well as cost. The same problem arises when the depth dimension of racks differs in addition to the above-described specifications for projections and through holes and notches, and it is necessary to prepare support rails having many kinds of depth dimensions suited to the depth dimensions of rack frames.
- In view of the foregoing and other exemplary problems, drawbacks, and disadvantages of the conventional techniques, it is an exemplary feature of the present invention to provide a rack system, a rack frame, a support rail, and a method of making a rack system which enable one support frame (e.g., support rail) to be mounted on different kinds of rack frames. In particular, for example, the present invention provides a rack which enables a support frame to be mounted on rack frames having different specifications for structures (e.g., positioning structures) for positioning the support frame in rack frames or rack frames having different depth dimensions.
- The present invention provides a rack system including a rack frame, a support rail which is fixable to the rack frame. A device is supportable by the support rail. Multiple positioning projections are provided on at least one of the rack frame and the support rail and each of which is fittable into positioning holes of different kinds provided in the other of the at least one of the rack frame and the support rail.
- [Exemplary Advantage of the Invention]
- According to the present invention, for example, one support rail may be fixed to rack frames having different positioning holes and rack frames having different depth dimensions, thereby increasing the versatility of the support rail. Likewise, for example, one rack frame may be fixed to support rails having different positioning holes. As a result, by simply preparing one support rail or one rack frame, a rack can be constructed in which wasted vertical space within the rack is eliminated regardless of the kinds of rack frames or the kinds of support rails and, at the same time, the cost of racks may be lowered by the versatility of the support rail or rack frames.

- [Exemplary Embodiment]
- Next, an exemplary embodiment of the present invention will be described. The present invention may provide
multiple positioning projections rack frame 2 andsupport rail 3 which can each fit intopositioning holes rack frame 2 andsupport rail 3. Furthermore, the exemplary embodiment may providemultiple positioning projections 61 or 62 provided onsupport rail 3 which can each fit intopositioning holes rack frame 2. -
FIG. 1 is a schematic perspective view of arack 1 of an exemplary embodiment,Rack 1 related to the present invention includesrack frame 2 andsupport rail 3 attached to rackframe 2 as an example. -
Rack frame 2 may be a frame body assembled from a metal material and the like. In this case, supportingposts 21 may each be installed in a standing manner (e.g., vertically) back and forth, such that right and left supportingposts 21 are each connected back and forth, and right and left in top and bottom end portions thereof bylateral frame members 22 to form the frame body. A bottom plate, a top plate and side plates (not shown for clarity) may cover up the interior of the rack frame as desired. Each of supportingposts 21 may be formed from a stem having a roughly L-shaped horizontal section, and on front and back surfaces of the supporting post, a large number of positioning holes 23 are opened in the back and forward directions with a prescribed vertical pitch size, for example. Positioninghole 23 may be formed as an angular hole or a round hole according to the kind of rack (i.e., rack frame 2). However, for example, the pitch size of positioning holes 23 may be common to various kinds of rack frames. The width dimension ofrack frame 2 in the right and left directions and the depth dimension thereof in the back and forward directions are each arbitrary for each kind of rack frame. - As shown in
FIG. 2 ,support rail 3 may include railmain body 4 which may be a roughly rectangular elongated plate in the back and forward directions, andauxiliary rail 5 which may be connected to railmain body 4 so as to be slidable in the length direction. Railmain body 4 may have, in one end portion thereof, fixingflange 6 which is formed by being bent at substantially right angles and also have, in an end portion ofauxiliary rail 5 on the opposite side, a fixingflange 7, which is formed by being bent at substantially right angles as with fixedflange 6. Furthermore, railmain body 4 may have, along a lower edge thereof,rail section 8 which may be formed by being bent at right angles in the direction opposite to fixingflanges - As shown in
FIG. 1 , thissupport rail 3 fixes each of the fixingflanges main body 4 andauxiliary rail 5 to supportingposts 21 on the frontside or backside ofrack frame 2, withrail section 8 directed inwardly, whereby a pair ofsupport rails 3 is fixed in a condition opposed to each other right and left in the same height position ofrack frame 2, and the right and left lower edge portions of a device to be mounted are supported in each ofrail sections 8 ofsupport rails 3, thereby to mount the device within the rack. - For example, in attaching the support rail of
FIG. 2 to the observer's left side of the interior ofrack frame 2 shown inFIG. 1 , fixingflange 6 of railmain body 4 is fixed to supportingpost 21 on the frontside ofrack frame 2 and fixingflange 7 ofauxiliary rail 5 is fixed to the supporting post on the backside. - Also, in attaching the
same support rail 3 to the right side in the interior ofrack frame 2, a support rail which is symmetric to supportrail 3 ofFIG. 2 is provided and this support rail is attached to rackframe 2. In this case,support rail 3 ofFIG. 2 may be used, and by fixing fixingflange 6 of railmain body 4 to supportingpost 21 on the backside and fixing fixingflange 7 ofauxiliary rail 5 to supportingpost 21 on the frontside,support rail 3 may be used as either of the right and left support rails. -
Auxiliary rail 5 may be formed as an elongated plate having a somewhat smaller vertical width dimension than that of railmain body 4. As described in detail later, a part of railmain body 4, in this case, two places in the back and forward directions along the vertical edge may be cut each to form a raised portion. As such, two pairs ofguide pieces 41 which may be vertically opposed to each other, may be formed.Auxiliary rail 5 is inserted into the region between theseguide pieces 41 so as to be movable in the length direction of railmain body 4. Also,stopper 51 may be integrally formed in one end portion ofauxiliary rail 5, so thatstopper 51 comes into contact withguide piece 41 during the movement ofauxiliary rail 5. Thus,auxiliary rail 5 is prevented from falling off from railmain body 4. -
FIG. 3 is an enlarged perspective view ofexemplary fixing flange 6 of railmain body 4 as viewed from the observer's right side. Incidentally, fixingflange 7 ofauxiliary rail 5 may have substantially the same construction as fixingflange 6 and, therefore, only fixingflange 6 is described here. Fixingflange 6 may be formed to be vertically elongated, and, on the front surface thereof, fixingflange 6 may include multiple positioning projections. For example, fiveangular projections 61 a to 61 e may be vertically formed integrally. - Also, in the middle portion of the front surface of fixing
flange 6 in the vertical direction whereangular projections 61 a to 61 e are not formed, tworound projections Round projections angular projections 61 a to 61 e may be substantially square shaped having almost the same side dimension as the diameter ofround projections - Also, the projecting height of
angular projections 61 a to 61 e is small, and the projecting height ofround projections angular projections 61 a to 61 e. Furthermore,round projections angular projections 61 a to 61 e are arranged in positions with a required vertical pitch size or in positions with a size which is a multiple of this pitch size. - Just under
angular projection 61 a in the top end portion among the five angular projections, slit 63 a may be formed in the width direction of fixingflange 6.Angular projection 61 c, which is the third one from the bottom, may be formed withintongue 64 formed by notching a part of fixingflange 6.Slit 63 a may be formed along a base portion oftongue 64. Theseslits angular projections flange 6, as described below. Furthermore,angular projection 61 e in the lowest bottom position may be formed by bending up the bottom end portion of fixingflange 6 in the front direction and working the bent up portion in angular form. - Device fixing screw holes 65 a, 65 b for fixing devices to be mounted, may be opened in
angular projections slits angular projections 61 a to 61 e. Also, rail fixingscrew hole 66 for fixingsupport rail 3 to rackframe 2 may be opened inangular projection 61 d, which is the second one from the bottom. Furthermore, adapter fixing screw holes 67 a, 67 b for fixing an adapter, which will be described below, may be formed in positions except for those of the angular projections and round projections of fixingflange 6. - In attaching
exemplary support rail 3 of the above-described construction toexemplary rack frame 2, as shown inFIG. 4 , the positioning holes formed in supportingpost 21 ofrack frame 2 areangular holes 23A, the front surface of fixingflange 6 ofsupport rail 3 is brought into close contact with the inner surface of supportingpost 21 andangular projections 61 a to 61 e provided in fixingflange 6 are fitted intoangular holes 23A, whereby positioning in the vertical and horizontal directions is performed. At this time, for example,round projections angular projections 61 a to 61 e (e.g., lower projections 61 a-61 e are wider thanhigher projections angular holes 23A. Thereafter,rail fixing screw 11 is threaded into rail fixingscrew hole 66 fromoutside rack frame 2 through theangular hole 23A, thereby allowing fixing flange 6 (i.e., support rail 3) to be fixed to rackframe 2. - This may apply also to fixing
flange 7 provided onauxiliary rail 5 on the side opposite to supportrail 3, for example. At this time,auxiliary rail 5 is moved with respect to railmain body 4 and the front surface of fixingflange 7 is brought into close contact with the supporting post on the backside ofrack frame 2, the angular projections are fitted into the angular holes in the same manner as in the frontside case, and fixingflange 7 is fixed to the supporting post by the rail fixing screw. - The same thing may apply also to the
support rail 3 which is fixed on the right side ofrack frame 2, for example. As a result, in a pair ofsupport rails 3 fixed so as to be horizontally opposed,rail sections 8 become opposed to each other. - Thereafter, as shown in
FIG. 5 , device 100 is inserted intorack frame 2 such that the right and left lower edge potions of device 100 are placed onrail sections 8. Device fixing screws 12, which have been inserted into fixing screw holes 102 provided infront panel 101 of device 100, are inserted intoangular holes 23A ofrack frame 2 and further threaded into device fixing screw holes 65 a, 65 b provided in fixingflange 6. Thus, device 100 is fixed to rackframe 2, and device 100 is mounted onrack 1. - On the other hand, as shown in
FIG. 6 , for example, when the positioning holes formed in supportingpost 21 ofrack frame 2 areround holes 23B, the front surface of fixingflange 6 ofsupport rail 3 brought into close contact with the inner surface (i.e., fixed surface 26) of supportingpost 21. Furthermore,round projections flange 6 are fitted intoround holes 23B, whereby positioning in the vertical and horizontal directions is performed. - At this time, for example,
angular projections 61 a to 61 e, which have a larger size than that ofround projections post 21, and not inserted intoround holes 23B. Thereafter,rail fixing screw 11 is threaded into rail fixingscrew hole 66 fromoutside rack frame 2 through theangular hole 23B. Thus,support rail 3 is fixed to rackframe 2. Also in this case, on the backside ofrack frame 2, fixingflange 7 is fixed to supportingpost 21 on the backside after the adjustment of the projecting length ofauxiliary rail 5. Also on the horizontally opposite side, device 100 may be mounted onrack 1, as shown inFIG. 5 , by fixingsupport rail 3. - In this exemplary embodiment,
round projections angular projections 61 a to 61 e. However,angular projections 61 a to 61 e may be formed with a size smaller than that ofround projections - Next as shown in
FIG. 7 , fixing portion (e.g., fixingflange exemplary adapter 9 having a positioning projection fitting intopositioning hole 23C which is provided in one ofrack frame 2 and support rail 3 (e.g.,positioning hole 23C inrack frame 2 is shown in this exemplary embodiment) of a kind different from one ofrack frame 2 and support rail 3 (e.g., adifferent rack frame 2 in this exemplary embodiment is shown) will be described. - As shown in
FIG. 7 , when a positioning projection provided on one ofrack frame 2 andsupport rail 3 cannot fit into, or be inserted to, a positioning hole provided on one ofrack frame 2 andsupport rail 3, anadapter 9 can be used. For example, when positioning holes 23 provided in supportingpost 21 ofrack frame 2 are small-diameter holes 23C into which the round projections and angular projections are incapable of fitting, and not round holes or angular holes,adapter 9 provided separately can be used. - In
exemplary adapter 9, small-diameter projections diameter holes 23C are formed on the front surface. By threading adapter fixing screws 13 which pierce throughadapter fixing holes flange 6,adapter 9 is integrally fixed to the front surface of fixingflange 6. Inadapter 9,clearance holes 93 a to 93 d to receiveround projections adapter 9 is fixed, the small-diameter projections diameter holes 23C of supportingpost 21. Thereafter,rail fixing screw 11 is threaded into rail fixingscrew hole 66 of fixingflange 6 in the same manner as shown inFIG. 4 orFIG. 6 , thereby fixingsupport rail 3 to rackframe 2. - By fixing
adapter 9 having projections of different specifications to the fixingflanges support rail 3, for example, it may be possible to attach the support rail of the exemplary embodiment to rackframe 2 having positioning holes of any kinds of specifications. Furthermore, by adjusting the substantial length ofsupport rail 3 by movingauxiliary rail 5, it may be possible to attach the support rail of the exemplary embodiment also to rackframe 2 having different depth dimensions. - The support rail of the exemplary embodiment has device fixing screw holes 65 a, 65 b for fixing a device to fixing
flange 6. However, according to the kind of a device, the device is fixed to rackframe 2 and in this case, device fixing screw holes 65 a, 65 b become unnecessary in fixingflange 6. Thus, although the device fixing screw holes may be left as they are,angular projection 61 a in the highest position shown inFIG. 3 in which device fixing screw holes 65 a, 65 b are provided andangular projection 61 c from the third one from the bottom, which is provided intongue 64, can be removed by being separated from fixingflange 6 by use of theslits flange 6. - Incidentally, in the construction of the exemplary embodiment including
guide piece 41 which supportsauxiliary rail 5 on railmain body 4 so as to be movable, as shown in detail inFIG. 8A , the portions near the upper edge and lower edge of railmain body 4 may be cut to form II-shaped (e.g., inverted U-shaped) raised portions so as to be opposed to each other and bent up in an L-shape, so that a gap, into whichauxiliary rail 5 can be inserted, is formed betweenauxiliary rail 5 and the outer surface of railmain body 4.Auxiliary rail 5 is movable in the length direction of railmain body 4, while the upper edge and lower edge are being guided, respectively by the upper andlower guide pieces 41. - In place of this construction, as shown in
FIG. 8B , a region from near the upper edge of railmain body 4 to the lower edge thereof may be cut to form a raised portion asguide piece 41A having a gap into whichauxiliary rail 5 can be inserted. - On the other hand, to prevent
auxiliary rail 5 from falling from railmain body 4, in the exemplary embodiment,stopper 51 may be provided in one end portion ofauxiliary rail 5, for example. As shown inFIG. 9A , this may be a tongue formed on one end edge ofauxiliary rail 5, and this tongue may be bent up at substantially right angles. - Alternatively, as shown in
FIG. 9B , a part of one end edge ofauxiliary rail 5 may be cut to form a trapezoidal raised portion asstopper 51A. Furthermore, as shown inFIG. 9C , a minute projection may be formed asstopper 51B. - In any case, in assembling
support rail 3,auxiliary rail 5 is inserted throughguide pieces main body 4 from one end side and is provided a stopper after the insertion. In the case ofFIGS. 9A and 9B , these parts may be bent after the insertion ofauxiliary rail 5 and in the case ofFIG. 9C , after the insertion, a part ofauxiliary rail 5 may be hammered out to form a projection by use ofwindow 43 provided in railmain body 4. As described above,stoppers guide pieces auxiliary rail 5 is prevented from falling off. - As a result, for example, in constructing the support rail of exemplary embodiment provided with the fixing flanges, the auxiliary rail, etc., separate members such as screws and rivets may be unnecessary. This is favorable for reducing the number of parts and associated costs.
- Incidentally, in the exemplary embodiment, as shown in
FIG. 2 , a part ofguide piece 41 is hammered out toward the inner surface asminute projection 42 so thatauxiliary rail 5 does not move excessively with respect to railmain body 4. By the contact of thisminute projection 42 with the outer surface ofauxiliary rail 5, the movement ofauxiliary rail 5 is resisted to some extent, and the moving position ofauxiliary rail 5 is moderated, thereby increasing the workability whensupport rail 3 is attached to rackframe 2. - Although in exemplary embodiment described above, five angular projections and two round projections are provided in the fixing flange, at least one projection may be provided as each kind of projection. However, to perform stable positioning, it is desirable to provide two or more projections vertically at required intervals. Also, projections of different kinds are not limited to the angular projections and round projections of the exemplary embodiment. Thus, the projections can be appropriately changed to adapt to the shape of positioning holes provided in the rack frame.
- In the exemplary embodiment,
multiple positioning projections 61, 62 which can each fit intodifferent positioning holes support rail 3 which can support device 100 to be mounted. Next, an example of multiple positioning projections being provided inrack frame 2 will be described. -
FIG. 10 shows an exemplary perspective view which shows how fixing is performed to rackframe 2 havingmultiple positioning projections rack frame 2 includes multiple positioning projections which can each fit into different positioning holes of different kinds of support rails 30.Angular projections 24A andround projections 24B are provided in fixing portion 6 a ofrack frame 20, andangular projections 24A can fit intoangular hole 68A provided insupport rail 30.Round projections 24B can be inserted intoangular hole 68A. As shown in the exemplary embodiment, by simply preparing one kind of rack frame, a rack is constructed in which wasted vertical space within the rack is eliminated regardless of the kinds ofsupport rail 30. - While this invention has been described with reference to exemplary embodiments, this description is not intended as limiting. Various modifications of the illustrative exemplary embodiments, as well as other exemplary embodiments of the invention, will be apparent to persons skilled in the art upon taking description as a whole. It is, therefore, contemplated that the appended claims will cover any such modifications or exemplary embodiments as fall within the true scope of the invention.
- Further, the inventor's intent is to encompass all equivalents of all the elements of the claimed invention even if the claims are amended during prosecution.
- This application is based on Japanese Patent Application No. 2005-009753 filed on Jan. 18, 2005 and including specification, claims, drawings and summary. The disclosure of the above Japanese Patent Application is incorporated herein by reference in its entirety.
