Description

[Technical field]

[0001] The present invention relates to a mounting structure for a support angle suitable for use in a rack capable of mounting a plurality of devices in multiple levels, such as a so-called 19-inch rack. [Background technology]

[0002] The rack R shown in Fig. 1 corresponds to a rack mount that allows devices with various functions to be stacked and has four mount frames 1 (1A to 1D) extending in the vertical direction. In this rack R, as shown in Fig. 8, a device (such as a rack-mounted electronic device) 2 inserted from the front is fixed to the front mount frames 1A and 1B by, for example, screwing, and the fixed device 2 is held horizontally. Each mount frame 1 has a plurality of holes 3 for fixing the device 2 at intervals in the vertical direction so that the holding height of the device 2 can be changed.

[0003] In such a rack R, for example, when the equipment 2 to be stored is heavy or has a long depth, support angles (not shown) are attached across the front and rear mount frames 1 (1A and 1C, 1B and 1D) to support the equipment 2. Furthermore, for equipment that is not configured to be directly fixed to the mount frame 1, a shelf is attached to the support angle and the equipment is placed on the shelf. Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, the support angle is attached to the mount frame 1 by tightening multiple screws and cage nuts using tools. However, this type of support angle attachment structure has the problem that it requires a lot of assembly work to attach the support angle, which takes a lot of time. Moreover, it is difficult for someone who does not use tools on a daily basis to perform the attachment work, and even for someone who is accustomed to using tools, it is extremely difficult to perform the attachment work alone using tools while holding the screws and the support angle in their hands at the same time, so in many cases the installation work needs to be done by multiple people. Furthermore, there is a risk that the screws will be lost during the installation work, or that the tools will interfere with the equipment 2, making the installation work difficult.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a mounting structure for a support angle that does not require tools and can simplify the installation work of a support angle. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the mounting structure for a support angle of the present invention is a mounting structure for a support angle that prevents the claw of the support angle from being released from the engagement with a specific portion of the mount frame by a fixing device, and is configured so that when, with the claw of the support angle engaged with the specific portion of the mount frame, an engaging protrusion on the fixing device is inserted into both the support hole of the mount frame and the supported hole of the support angle, which are mutually communicating, and an elastic engaging piece provided on the fixing device separately from the engaging protrusion is elastically engaged with the support angle, the engaging protrusion engages and abuts against the edge of the support hole, thereby entering a locked state that prevents the support angle from moving in the direction in which the engagement is released (Claim 1).

[0007] In the above-mentioned support angle mounting structure, the support angle may have a plurality of claws corresponding to at least one of the mount frames, and any one of the claws may be selected to engage with a specific location on the mount frame to achieve the locked state (Claim 2).

[0008] In the mounting structure of the above support angle, in addition to the engaging protrusion and the elastic engaging piece, one of a concave portion and a convex portion which fit together when the locked state is achieved may be provided on the support angle, and the other may be provided on the fixing device (Claim 3).

[0009] In the above-mentioned support angle mounting structure, the support angle may be a metal member, the claw may be formed by cutting out a part of the support angle, and the supported hole may be a hole formed in the support angle by this cutting out (Claim 4). Effect of the Invention

[0010] The present invention provides a mounting structure for a support angle that does not require tools for the mounting work of a support angle, making the work easier.

[0011] In other words, in the support angle mounting structure of the invention as claimed in each claim of the present application, the support angle can be mounted to the mount frame in a stably state by engaging the claws of the support angle with specific locations on the mount frame, inserting the engaging protrusions of the fixing device into the support holes and supported holes, and elastically engaging the elastic engaging piece with the support angle, and each of the steps can be easily performed with approximately one touch without the need for tools.

[0012] Here, for example, when attaching one support angle across two mount frames that are located apart, if there is only one claw corresponding to each mount frame (i.e., if the support angle has a total of two claws), the support angle cannot be attached unless the distance between the two mount frames is standardized. However, in the support angle mounting structure of the invention of claim 2, since there are multiple claws corresponding to at least one mount frame, the distance between the two mount frames can be set to multiple values, thereby increasing the freedom to set the position of the mount frames.

[0013] In the mounting structure for the support angle of the invention as claimed in claim 3, the support angle and the fixing device engage with each other through a concave-convex fit when the support angle is locked. This acts as a guide for elastically engaging the elastic engagement piece with the support angle, allowing this elastic engagement to be carried out smoothly. In addition, the above-mentioned concave-convex fit makes the posture of the fixing device in the locked state more stable, and makes it possible to more effectively suppress movement of the support angle in the direction in which the engagement is released.

[0014] In the support angle mounting structure of the invention according to claim 4, the supported hole can be formed in the process of forming the claws on the support angle, and there is no need to use a separate part to provide the claws, which allows for a simplified structure and reduced manufacturing labor and costs.

[0016] An embodiment of the present invention will be described below.

[0017] As is clear from comparing Figures 1 and 2, the rack R shown in Figures 1 and 2 is provided with a support angle mounting structure that enables support angles 4 to be attached across two mount frames 1 (1A and 1C, or 1B and 1D) that are spaced apart from each other in the front and rear.

[0018] The mount frame 1 is a bent plate-like member made of metal, for example, that is mounted at four locations on the rack R: the front right, front left, rear right, and rear left.

[0019] As shown in FIG. 3, the mount frame 1A located at the right front part of the rack R has a shape in which an outer bent part 5 having a large L shape in a plan view is connected to an inner bent part 6 having a small L shape in a plan view. The outer bent part 5 is constituted by a first outer side surface part 5a facing the outer side in the front-rear direction of the rack R and extending in the left-right direction of the rack R, and a second outer side surface part 5b facing the outer side in the left-right direction of the rack R and extending in the front-rear direction of the rack R, and the inner bent part 6 is constituted by a first inner side surface part 6a extending in the left-right direction of the rack R, and a second inner side surface part 6b extending in the front-rear direction of the rack R. Here, the first inner side surface part 6a is shorter than the first outer side surface part 5a, and the second inner side surface part 6b is shorter than the second outer side surface part 5b in a plan view, extends approximately parallel to the first outer side surface part 5a, and is located inside the rack R (inside in the front-rear direction and left-right direction of the rack R). The other mount frames 1B to 1D have the same structure as the mount frame 1A.

[0020] A plurality of holes (through holes) 3 for fixing a device 2 (see FIG. 8) are provided at intervals in the vertical direction on the first outer side surface portion 5a of each mount frame 1.

[0021] Meanwhile, the support angle 4 is, for example, an L-shaped metal member used to support the lower part of the device 2 fixed to the mount frame 1 or to attach a shelf. The support angle 4 in this example has a vertical surface portion 7 that extends substantially vertically along the inner surface side of each of the second inner surface portions 6b of two mount frames 1 (1A and 1C, or 1B and 1D) that are positioned separately in the front and rear, and a horizontal surface portion 8 that extends substantially horizontally from one end (the lower end in the illustrated example) of the vertical surface portion 7 toward the inside of the rack R.

[0022] Below, a method for mounting the support angle 4 using the support angle mounting structure of this embodiment will be described, along with a more detailed description of the configurations of the mount frame 1 and the support angle 4. This mounting method involves carrying out the following steps (1) to (3).

[0023] (1) As shown in Fig. 5(A), the claw 9A provided on the vertical surface portion 7 of the support angle 4 is inserted into a square hole (an example of a through hole) 10A provided on the second inner side surface portion 6b of the mount frame 1, and is engaged with the edge of this square hole 10A (an example of a specific portion of the mount frame) (see Fig. 5(C)). This engagement brings into communication between the irregular square hole 11 located one position below the square hole 10A into which the claw 9A is inserted on the second inner side surface portion 6b of the mount frame 1, and a square hole 12A (an example of a supported hole) provided on the vertical surface portion 7 of the support angle 4 so as to be connected to the claw 9A (see Fig. 5(B)).

[0024] As shown in Figures 4(C) and (D), the claws 9A are provided at both ends of the vertical surface portion 7 of the support angle 4 in the longitudinal direction, and protrude in the opposite direction to the extension direction of the horizontal surface portion 8 from the vertical surface portion 7. In this example, the support angle 4 is a metal member, the claws 9A are formed by cutting out a part of the support angle 4 (the vertical surface portion 7), and the square hole 12A is a hole formed in the support angle 4 (the vertical surface portion 7) by this cutting and raising. Therefore, the square hole 12A can be formed in the process of forming the claws 9A on the support angle 4, and there is no need to use a separate member to provide the claws 9A, which simplifies the configuration and reduces the manufacturing man-hours and costs.

[0025] As shown in FIG. 5(A), the square hole 10A is a hole located above the irregular square hole (an example of a support hole) 11, and the irregular square hole 11, the square hole 10A located above it, and the square hole (an example of a through hole) 10B located below the irregular square hole 11 constitute one through hole group G, and a plurality of through hole groups G are arranged in the longitudinal direction (up and down direction) of the second inner side surface portion 6b of the mount frame 1. More specifically, the square hole 10A is a square or rectangular through hole, the square hole 10B is a through hole with the same structure as the square hole 10A, and the irregular square hole 11 is a through hole with notches for markers on the left and right edges of the square or rectangular hole. In each through hole group G, the distance from the irregular square hole 11 to the square hole 10A is the same as the distance from the irregular square hole 11 to the square hole 10B. In addition, the distance between adjacent through hole groups G vertically (the distance from the square hole 10A of the lower through hole group G to the square hole 10B of the upper through hole group G) is uniform, and in this example, the distance between adjacent through hole groups G vertically is made smaller than the distance from the irregular square hole 11 in each through hole group G to the square holes 10A, 10B above and below it.

[0026] (2) The engaging projections 14 of the fasteners 13 are inserted into both the irregular square hole 11 and the square hole 12A that are now in communication with each other in the above step (1) (see FIGS. 5(B) and (C)).

[0027] Fixture 13 is, for example, a member made of synthetic resin, and as shown in Figures 4(A) and (B), has a generally long plate-shaped main body 15. If the side of main body 15 shown in Figure 4(A) is the front side and the side shown in Figure 4(B) is the rear side, the periphery of the rear surface of main body 15 protrudes rearward, and the periphery of main body 15 is thicker than the center.

[0028] Furthermore, an engagement protrusion 14 extends rearward and outward in the longitudinal direction (in the direction moving away from the other longitudinal end) from one end side of the rear surface of the main body 15. The engagement protrusion 14 has a substantially square cylindrical base 14a that protrudes rearward from the rear surface of the main body 15, and a tip 14b that extends from the rear end of the base 14a toward the longitudinal outward direction of the main body 15, and the vertical center part on the rear side of the tip 14b is cut out by a notch groove 14c except for its tip part.

[0029] Here, as shown in Figures 5(B) and (C), the tip portion 14b has a shape or size that prevents it from being inserted into the irregular square hole 11 of the mount frame 1 that communicates with the square hole 12A of the support angle 4, even if the fixing device 13 is brought close while keeping the main body portion 15 approximately parallel to the second inner surface portion 6b of the mount frame 1. However, as shown in Figure 6(A), the tip portion 14b is configured so that it can be inserted by making the longitudinal direction of the main body portion 15 somewhat inclined relative to the second inner surface portion 6b.

[0030] (3) While the engagement protrusion 14 of the fixing device 13 inserted into the irregular square hole 11 of the mount frame 1 in the above step (2) is kept from falling out of the irregular square hole 11, the fixing device 13 is rotated around the vertical axis so that the longitudinal direction of the main body portion 15, which is inclined with respect to the second inner side surface portion 6b, becomes parallel to the second inner side surface portion 6b as shown in FIG. 6(A). Then, the elastic engagement piece 16 provided on the fixing device 13 on the opposite side to the engagement protrusion 14 in the longitudinal direction will eventually elastically engage with the edge of the longitudinal end of the support angle 4 (see FIG. 6(B)-(D)). As a result, the engagement protrusion 14 comes into engagement with the edge of the irregular square hole 11, and a locked state is created in which the movement of the support angle 4 in the direction in which the locking in the above step (1) is released is suppressed. Note that in order to enable the fixing device 13 to rotate as described above while the engagement protrusion 14 is inserted into the irregular square hole 11, appropriate portions of the engagement protrusion 14 are chamfered or the like.

[0031] As shown in FIG. 4(B), the elastic engagement piece 16 is a generally L-shaped portion in a plan view that protrudes rearward and longitudinally inward (in the direction approaching one longitudinal end) from the other longitudinal end side of the rear surface of the main body portion 15 of the fixing device 13. Specifically, it has a generally thin plate-like base portion 16a that protrudes rearward from the rear surface of the main body portion 15, and a tip portion 16b that extends longitudinally inward from the rear end of the base portion 16a of the main body portion 15. The base portion 16a of the elastic engagement piece 16 is configured to be thinner than the base portion 14a of the engagement projection 14 so as to be elastically deformable.

[0032] To release the locked state, as shown in Figures 4(A) and (B), the knob portion 20 of the fixture 13, which protrudes further toward the other end of the fixture 13 in the longitudinal direction than the elastic engagement piece 16, is pulled forward (in the direction in which the horizontal surface portion 7 extends) to release the elastic engagement of the elastic engagement piece 16 with the edge of the end of the longitudinal direction of the support angle 4. Note that, as shown in Figures 6(B) and (C), there is sufficient space around the knob portion 20 in the locked state to insert fingers, so this release operation can be easily performed.

[0033] As explained above, the mounting structure of the support angle in this example is designed to prevent the claw 9A of the support angle 4 from releasing its engagement with the edge of the square hole 10A of the mount frame 1 by using the fixing device 13. With the claw 9A of the support angle 4 engaged with the edge of the square hole 10A of the mount frame 1, the engaging protrusion 14 on the fixing device 13 is inserted into both the square hole 11 of the mount frame 1 and the square hole 12A of the support angle 4, which are connected to each other, and an elastic engaging piece 16 provided on the fixing device 13 separately from the engaging protrusion 14 is elastically engaged with the support angle 4, so that the engaging protrusion 14 abuts against the edge of the square hole 11, entering a locked state which prevents the support angle 4 from moving in the direction in which the engagement is released.

[0034] In the support angle mounting structure of this example, the support angle 4 can be attached to the mount frame 1 in a stably state by engaging the claw 9A of the support angle 4 with the edge of the square hole 10A of the mount frame 1, and then inserting the engagement protrusion 14 of the fastener 13 into the square holes 11 and 12A and elastically engaging the elastic engagement piece 16 with the support angle 4. Each of the steps can be performed easily with just one touch without the need for tools.

[0035] In this example, when the support angle 4 is locked in the step (3), the fitting protrusion (an example of a convex portion) 18 (see FIG. 4(B)) provided on the fixing device 13 is fitted into an oblong hole (an example of a concave portion) 17A (see FIGS. 4(C) and (D)) located on the outer side of the support angle 4 in the longitudinal direction with respect to the square hole 12A in the support angle 4 (see FIG. 6(B)). If the support angle 4 and the fixing device 13 are configured to fit into each other in this manner when the support angle 4 is locked, the fitting protrusion (an example of a convex portion) 18 (see FIG. 4(B)) provided on the fixing device 13 is fitted into the rectangular hole 12A in the longitudinal direction of the support angle 4 (see FIG. 6(B)). When the support angle 4 and the fixing device 13 are configured to fit into each other in this manner when the support angle 4 is locked, the fitting protrusion acts as a guide for elastically engaging the elastic engagement piece 16 with the support angle 4, so that the elastic engagement can be performed smoothly. In addition, the fitting protrusion makes the posture of the fixing device 13 in the locked state more stable, and the movement of the support angle 4 in the direction in which the locking in the step (1) is released can be more effectively prevented.

[0036] In addition, in this example, the support angle 4 is provided with two claws 9 corresponding to one mount frame 1, as shown in Figures 4(C) and (D), so that for each of the two claws 9A, a claw 9B is provided that is positioned at a distance on the inside in the longitudinal direction of the support angle 4. The support angle 4 is configured so that the locked state can be achieved by selecting either claw 9A, 9B to engage with the edge of the square hole 10A in the mount frame 1.

[0037] 4(C) and (D), the claws 9B are connected to the rectangular holes 12B on the vertical surface 7 of the support angle 4, and the two claws 9B are provided with an oblong hole (an example of a recess) 17B and an opening 19 on the inner side in the longitudinal direction of the support angle 4. After the claws 9B are selected and engaged with the edge of the rectangular hole 10A of the mount frame 1, the engagement projection 14 of the fixture 13 is inserted obliquely into the irregular rectangular hole 11 that is inserted into the rectangular hole 12B, and in this state, the fixture 13 is rotated so that the elastic engagement piece 16 of the fixture 13 elastically engages with the edge of the opening 19, and at this time, the fitting projection 18 of the fixture 13 fits into the rectangular hole 17B. The claws 9B, the rectangular holes 12B, and the oblong holes 17B have the same configuration as the claws 9A, the rectangular holes 12A, and the oblong holes 17A, respectively. Furthermore, opening 19 may have any size and shape that does not prevent gripping portion 20 from being pinched with fingers when releasing the locked state.

[0038] For example, when attaching the support angle 4 across two mount frames 1A, 1C that are positioned at a distance from each other in front of and behind the rack R, if there is only one claw 9 corresponding to each mount frame 1A, 1C (i.e., the support angle 4 has a total of two claws 9), the support angle 4 cannot be attached unless the distance between the two mount frames 1A, 1C is standardized. However, in this example, since there are two claws 9 corresponding to one mount frame 1, the distance between the two mount frames 1A, 1C can be set to multiple values, increasing the freedom in setting the position of the mount frame 1.

[0039] As is clear from the above description, among the square holes 10A, 10B and irregular square hole 11 that constitute the group of through-holes G (see FIG. 5(A)), the square hole 10B is not used in this example, but if the mount frame 1 is turned upside down, the square hole 10B plays the same role as the square hole 10A. In other words, the mount frame 1 has a structure that is reversible up and down, and for example, the mount frame 1A provided on the right front of the rack R can be used not only as the mount frame 1D provided on the left rear, but also as the mount frame 1B provided on the left front and the mount frame 1C provided on the right rear. In addition, the support angle 4 also has a structure that is reversible between the front and rear of the rack R, and the same support angle 4 can be used for the mount frames 1A and 1C and the mount frames 1B and 1D.

[0040] 3, fixing holes 21 are provided at both longitudinal ends of the vertical surface portion 7 of the support angle 4, which can be used to fix the support angle 4 to the mount frame 1 or to fix a shelf or the like to the support angle 4. In addition, a plurality of through holes 22 are provided at intervals along the entire longitudinal direction of the horizontal surface portion 8 of the support angle 4, which can be used to pass cables connected to the equipment 2, to pass binding devices (such as bands) for bundling the cables, or to fix a shelf.

[0041] It is to be noted that the present invention is not limited to the above-described embodiment, and can be modified in various ways without departing from the spirit and scope of the present invention. For example, the following modifications can be mentioned.

[0042] In the above embodiment, for example as shown in FIG. 3, the horizontal surface portion 8 is connected to the underside of the vertical surface portion 7, which has the advantage of reducing the dead space that occurs below the support angle 4 attached to the lowest side of the rack R. However, this is not limited to this, and for example, the horizontal surface portion 8 may be connected to the upper side of the vertical surface portion 7.

[0043] In the above embodiment, there are two claws 9 corresponding to one mount frame 1, but this is not limited to the above, and only one claw 9 may be provided corresponding to one mount frame 1, or conversely, three or more claws 9 may be provided corresponding to one mount frame 1, and the locked state may be achieved by selecting any one of the claws 9 to engage with a specific location on the mount frame 1.

[0044] In the above embodiment, for example, as shown in FIG. 5(A), the claw 9A extends so as to hang down from the upper edge of the rectangular hole 12A. However, this is not limited to this, and for example, as shown in FIG. 7(A), the claw 9A may extend so as to hang down from the lower edge of the rectangular hole 12A (the same applies to the claw 9B).

[0045] In this case, as shown in Fig. 7(B), in the above step (1), the claw 9A is inserted into the retaining hole (square hole 11 in the illustrated example), and in the above step (2), the engagement protrusion 14 of the fastener 13 is inserted into the retaining hole (square hole 11). Alternatively, in the above step (1), if the vertical dimension of the square hole 12A is made relatively large (and in some cases the vertical dimension of the vertical surface portion 7 is also relatively large) so that the square hole 12 communicates with both the irregular square hole 11 and the square hole 10 above it when the claw 9A is inserted into the irregular square hole 11 one below the retaining hole (for example, square hole 10A) and the claw 9A is engaged with the edge of the irregular square hole 11, then in the above step (2), the engagement protrusion 14 of the fastener 13 can be inserted into the retaining hole (square hole 10A) one above the irregular square hole 11 into which the claw 9A is inserted.

[0046] In this way, in (the second inner side surface portion 6b of) the mount frame 1, the hole into which the claw 9A is inserted and engaged and the hole into which the engaging protrusion 14 of the fastener 13 is inserted and engaged may be the same or different. Furthermore, in the above embodiment, the square hole 12A connected to the claw 9A is used as the supported hole (hole for communicating with the support hole), but a separate hole not connected to the claw 9A may be provided and used as the supported hole.

[0047] In the above embodiment, the support angle 4 is provided with an elongated hole 17A (see Figures 4C and 4D) as a recess, and the fixing device 13 is provided with an engaging protrusion 18 (see Figure 4B) as a protrusion, so that the two are configured to be able to fit together. However, the present invention is not limited to this, and the support angle 4 may be provided with a protrusion and the fixing device 13 with a recess, so that the two are configured to be able to fit together.

[0048] In the above embodiment, as shown in Figure 4 (D), the claws 9 (9A, 9B) provided on both ends of the longitudinal direction of the vertical surface portion 7 of the support angle 4 both extend downward. However, this is not limited to the above. For example, as shown in Figure 9 (A), the claws 9 (9A, 9B) provided on one end of the longitudinal direction of the vertical surface portion 7 of the support angle 4 may extend downward, and the claws 23 (23A, 23B) provided on the other end may extend sideways (in the illustrated example, they are extended outward in the longitudinal direction of the vertical surface portion 7, but they may also extend in the opposite direction).

[0049] To attach the support angle 4 shown in Fig. 9(A) to two mount frames 1 separated in the front and rear, as shown in Fig. 9(B), the claw 23 (e.g., claw 23A) is inserted sideways into the irregular square hole 11 of one of the mount frames 1 and engaged with the edge, and then the claw 9 (e.g., claw 9A) is engaged with the other mount frame 1, and the fastener 13 is attached so as to be in a locked state that prevents the claw 9 from being released (see Fig. 9(C)). In other words, when the claw 23 is inserted into one of the mount frames 1 and engaged with the edge, and then the claw 9 is engaged with the other mount frame 1, the claw 23 is in a locked state that prevents it from moving in a direction that removes it from one of the mount frames 1, so there is no need to use the fastener 13 to prevent the claw 23 from being released. The engagement of the claw 9 with the other mount frame 1 and the attachment of the fastener 13 can be performed by the method shown in Figs. 5(A) to (C) and Figs. 6(A) to (D) described in the above embodiment.

[0050] It goes without saying that the above modifications may be combined as appropriate. [Explanation of symbols]
