Summary of Invention

Problems to be Solved by the Invention

[0004] However, in the cabinet rack of Patent Document 1, when fixing equipment to the mount angle with screws or the like, for example, two persons perform the work, one worker holds the equipment in alignment with the appropriate position of the mount angle, and the other worker screws the equipment to the mount angle. For this reason, work efficiency is poor. In addition, when a single worker mounts the equipment, the worker must support the equipment with one hand and tighten the screws into the mount angle with the other hand, which puts the equipment in an unstable state and also has the problem of poor workability.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide an equipment mounting fixture and a mounting method that allow a single worker to easily mount equipment on an equipment storage rack.

[0009] An embodiment of the equipment fixture and mounting method according to the present invention will be described with reference to the drawings. In the present embodiment, as an example of the equipment fixture according to the present invention, as shown in Figures 1 to 3, description will be given by taking equipment fixture 3 for fixedly storing, for example, a hard disk drive unit (hereinafter referred to as HDD unit) 1 as equipment in a stowable equipment storage rack (hereinafter referred to as rack) 2 as an example.

[0010] [Configuration of Rack 2] First, the rack 2 will be described. The rack 2 includes, for example, a metal housing frame 20, and mounting angles 25 for attaching the HDD unit 1.

[0011] As shown in Figure 1, the housing frame 20 includes an upper frame 21 framed in a rectangular shape, a lower frame 22 framed in the same shape as the upper frame 21, and four vertical frames 23 that connect the upper frame 21 and the lower frame 22 vertically.

[0012] The upper and lower ends of the four vertical frames 23 are joined at the four corners of the upper frame 21 and the lower frame 22 that face each other with a gap in the vertical direction, so as to connect the upper frame 21 and the lower frame 22. That is, the housing frame 20 included in the rack 2 of the present embodiment has a rectangular planar shape, and is framed to border each side of a cuboid that is elongated in the vertical direction. The HDD unit 1 is accommodated inside the housing frame 20 through a space between two of the four vertical frames 23.

[0013] In the following description, when the HDD unit 1 is accommodated, the side on which the two vertical frames 23 through which the HDD unit 1 passes are arranged is defined as the front side, the opposite side is defined as the back side, and the direction in which the HDD unit 1 passes is defined as the depth direction. Further, the left-right direction is defined such that, for an operator standing on the front side of the rack 2 facing the rack 2, the side to the operator's left is the left side, and the side to the operator's right is the right side.

[0014] For each part of the rack 2, as well as for the HDD unit 1 and the equipment fixture 3 attached to the rack 2 even in their standalone states, the directions are described with reference to the left-right direction and the depth direction when they are attached to the rack 2.

[0015] Between two of the four vertical frames 23 that are aligned in the depth direction, a plate-shaped reinforcing member 24 is stretched and fixed at the top and bottom. In addition, a mounting angle 25 is attached to each of the two vertical frames 23 that are located on the front side of the four vertical frames 23. The mounting angle 25 is attached along almost the entire length of the vertical frame 23.

[0016] The mounting angle 25 has a frame fixing portion 26 that is plate-shaped and fixed to the vertical frame 23, and a unit mounting portion 27 that is plate-shaped and to which the HDD unit 1 is attached. The mounting angle 25 has the front end of the frame fixing portion 26 and one end of the unit mounting portion 27 in the left-right direction connected, forming an angle of approximately 90 degrees so that the cross-sectional shape is L-shaped.

[0017] The pair of mounting angles 25 attached to the left and right vertical frames 23 are made of the same material and are attached to each vertical frame 23 in a reversed state.

[0018] The unit mounting portion 27 is provided with multiple screw holes (hereinafter referred to as mounting screw holes) 27A (Figure 2) along the vertical direction, and the multiple mounting screw holes 27A are arranged at specific intervals. The frame fixing portions 26 of each mounting angle 25 are fixed to the two front vertical frames 23 by abutting against each other on opposing surfaces.

[0019] The mounting angles 25 attached to each vertical frame 23 are positioned such that the unit mounting portion 27 protrudes from the side where the two vertical frames 23, arranged on the left and right, face each other. The front surface 27B of the unit mounting portion 27 is positioned to be approximately flush with the front surface 23A of each vertical frame 23. Furthermore, the front surfaces 27B of the unit mounting portion 27 on the left and right mounting angles 25 are arranged to form the same plane, and the position of each mounting screw hole 27A on the left mounting angle 25 is positioned to be at the same height as the position of each mounting screw hole 27A on the right mounting angle 25. Therefore, when the HDD unit 1 is brought into contact with the mounting angle 25 from the front, the HDD unit 1 is mounted in the correct position and orientation.

[0020] [HDD Unit 1 Configuration] The HDD unit 1 is shaped like a rectangular parallelepiped, and its outer perimeter is covered by a front panel 1A located at the front, a rear panel 1B located at the back, left panels 1C and 1D located on the left and right sides, and upper panels 1E and 1F located at the top and bottom. The left panel 1C and the right panel 1D are each provided with multiple panel screw holes (not shown) for fixing the connecting members 30 of the equipment mounting bracket 3.

[0021] [Configuration of equipment mounting bracket 3] The equipment mounting bracket 3 includes a connecting member 30 that connects the HDD unit 1 and the mounting angle 25, a fixing screw 33 that secures the connecting member 30 to the mounting angle 25, and a locking screw 34 that is screwed into the mounting angle 25 to lock the connecting member 30.

[0022] As shown in Figure 4, the fixing screw 33 has a fixing screw portion 33A and a fixing head 33B having a diameter D2 that is larger than the outer diameter D1 of the fixing screw portion 33A. The locking screw 34, as shown in Figure 5, is a so-called stepped screw and has a locking screw portion 34A, a locking head 34B having a diameter D4 that is larger than the outer diameter D3 of the locking screw portion 34A, and an enlarged diameter shaft portion 34C provided between the locking screw portion 34A and the locking head 34B, having a diameter D5 that is larger than the outer diameter D3 of the locking screw portion 34A and smaller than the diameter D4 of the locking head 34B, and having no threads formed on its outer circumference. The length of the enlarged diameter shaft portion 34C is formed to be longer than the plate thickness of the angle fixing portion 32 of the connecting member 30, which will be described later.

[0023] The connecting members 30 are fixed one each to the left panel 1C and the right panel 1D of the HDD unit 1, and then fixed to the mounting angle 25. In other words, the HDD unit 1 is attached to the mounting angle 25 via the connecting members 30 and housed in the rack 2.

[0024] As shown in Figures 6 to 8, the connecting member 30 has a plate-like structure and includes an equipment fixing portion 31 that is screwed to the left panel 1C or right panel 1D of the HDD unit 1 with mounting screws 35, and an angle fixing portion 32 that is plate-like and fixed to the mounting angle 25.

[0025] The front end of the equipment fixing part 31 is connected to one end of the angle fixing part 32 in the left-right direction, and the connecting member 30 is formed by bending a steel plate, for example, so that its planar cross-sectional shape forms an L-shape at an angle of approximately 90 degrees.

[0026] The connecting members 30 attached to the left and right sides of the HDD unit 1 are identical members, but are used in a reversed state. The connecting members 30 are positioned on the HDD unit 1 such that the front surface 32E of the angle fixing part 32 and the front surface 1G of the front panel 1A of the HDD unit 1 are approximately flush.

[0027] Therefore, the device fixing part 31 is provided with through holes 31A through which mounting screws 35 are inserted, at a position that overlaps with the panel screw holes provided on the left panel 1C or right panel 1D when the device fixing part 31 is brought into contact with the left panel 1C or right panel 1D of the HDD unit 1. If the through holes 31A are provided at positions corresponding to multiple types of devices, the device can be attached to multiple types of devices, thereby improving versatility.

[0028] In the equipment fixing portion 31, the area around the insertion hole 31A is provided has a recessed area 31B that is bent in a stepped manner so as to be recessed toward the HDD unit 1 side over a larger area than the head of the mounting screw 35.

[0029] As shown in Figure 8, the angle fixing portion 32 has two fixing holes 32A through which fixing screws 33 for fixing the HDD unit 1 to the mounting angle 25 are inserted, and two locking holes 32B through which locking screws 34 for locking the HDD unit 1 are inserted. The two locking holes 32B are provided on both ends in the longitudinal direction, i.e., the vertical direction, of the angle fixing portion 32, and the two fixing holes 32A are provided between the two locking holes 32B at an appropriate interval.

[0030] The same connecting member 30 is attached to the left panel 1C and the right panel 1D of the HDD unit 1. When the unit is housed in the rack 2, the lower of the two locking holes 32B of each connecting member 30 attached to the HDD unit 1 is locked with a locking screw 34, and a fixing screw 33 is inserted through the two fixing holes 32A. In other words, the upper of the two locking holes 32B is provided to make the connecting members 30 attached to the left and right sides of the HDD unit 1 common.

[0031] The fixing hole 32A is an elongated hole that is long in the left-right direction, and its width in the vertical direction is wider than the outer diameter D1 of the fixing screw portion 33A of the fixing screw 33 and narrower than the diameter D2 of the fixing head 33B. The locking hole 32B has a shape in which an enlarged hole portion 32C, which is larger than the diameter D4 of the locking head 34B of the locking screw 34, and a small hole portion 32D, which is smaller than the diameter D4 of the locking head 34B of the locking screw 34 but larger than the diameter D5 of the enlarged shaft portion 34C, are connected vertically.

[0032] The two locking holes 32B provided on the upper and lower ends of the angle fixing portion 32 are arranged such that the enlarged portion 32C is located on the upper and lower ends relative to the smaller portion 32D. Therefore, when the connecting member 30 is attached to the left panel 1C and the right panel 1D of the HDD unit 1, the locking hole 32B located on the lower end is formed such that the smaller portion 32D is located above the enlarged portion 32C.

[0033] The centers of the two fixing holes 32A and the centers of the small holes 32D in the two locking holes 32B are aligned with the spacing of the mounting screw holes 27A provided in the mounting angle 25. Therefore, when the angle fixing portion 32 of the connecting member 30 is positioned opposite the mounting angle 25, the centers of the fixing holes 32A and the centers of the small holes 32D in the locking holes 32B of the angle fixing portion 32 can be aligned with the positions of the mounting screw holes 27A of the mounting angle 25.

[0034] [How to install HDD unit 1] Next, we will describe how to mount the HDD unit 1 to the rack 2 using the equipment mounting components. Figure 9 is a flowchart showing how to mount the HDD unit 1 to the rack 2. The work shown in Figure 9 can be performed by one worker.

[0035] The worker first screws the connecting member 30 to the left panel 1C and right panel 1D of the HDD unit 1 to be mounted on the rack 2, as shown in Figure 10 (first step S1). At this time, the connecting member 30 is attached to the HDD unit 1 such that the front surface 1G of the front panel 1A of the HDD unit 1 and the front surface 32E of the angle fixing portion 32 of the connecting member 30 are almost flush.

[0036] First, the worker inserts the locking screws 34 into the mounting screw holes 27A on the left and right mounting angles 25 that correspond to the positions where the HDD unit 1 is to be installed, and screws them in from the front to the back in the depth direction (second step S2). As a result, the locking screws 34 are installed on the left and right mounting angles 25 in the same height mounting screw holes 27A, with the screws protruding toward the front in the depth direction. At this time, as shown in Figure 11, the enlarged diameter shaft portion 34C creates a gap in the depth direction between the front surface 27B of the unit mounting portion 27 and the back surface 34D of the locking head 34B of the locking screw 34. Note that the order of the first step S1 and the second step S2 may be reversed.

[0037] Next, the worker inserts the HDD unit 1 from the rear panel 1B side, through the two front vertical frames 23 that make up the rack 2, toward the rear. Then, as shown in Figures 12 and 13, the worker inserts the locking head 34B of the locking screw 34 into the enlarged hole 32C of the locking hole 32B provided on the lower side of the left and right connecting members 30 attached to the HDD unit 1, and then moves the HDD unit 1 downward, and as shown in Figure 14, the worker hooks the upper edge 32G that forms the small hole 32D of the locking hole 32B in the connecting member 30 onto the enlarged diameter shaft 34C of the locking screw 34 to lock it in place (third step S3).

[0038] At this time, the connecting member 30 provided on the front part of the HDD unit 1 is locked to the mounting angle 25 provided on the front part of the rack 2. As shown in Figure 15, the HDD unit 1, whose center of gravity is located behind the mounting angle 25, tilts due to its own weight so that the rear side, i.e., the rear panel 1B side, is located below the front side.

[0039] As the HDD unit 1 tilts, the upper ends 32H of the angle fixing portions 32 of the left and right connecting members 30 attached to the HDD unit 1 come into contact with the front surface 27B of the unit mounting portion 27, and the lower side of the angle fixing portion 32 comes into contact with the rear surface 34D of the locking head 34B of the locking screw 34. As a result, rotational movement of the HDD unit 1 that causes the rear side to drop is restricted, and it is temporarily held in the rack 2 in a tilted state. At this time, the upper edge 32G that forms the small hole portion 32D of the locking hole 32B in the connecting member 30 is hooked onto the enlarged diameter shaft portion 34C of the locking screw 34, which does not have threads formed on its outer circumference. Therefore, when the HDD unit 1 tilts due to its own weight, the upper edge 32G that forms the small hole portion 32D of the locking hole 32B in the connecting member 30 slides smoothly along the enlarged diameter shaft portion 34C, making it easy for the connecting member 30 to tilt and allowing it to tilt smoothly.

[0040] The length of the enlarged diameter shaft portion 34C of the locking screw 34 is set such that, when the angle fixing portion 32 of the connecting member 30 is in contact with and temporarily held by the locking head 34B of the locking screw 34, the fixing screw portion 33A of the fixing screw 33, which is inserted from the front side into the fixing hole 32A of the inclined angle fixing portion 32, can be screwed into the mounting screw hole 27A.

[0041] Next, as shown in Figure 16, the worker inserts the fixing screws 33 through the two fixing holes 32A provided in the left and right connecting members 30 and screws them into the mounting screw holes 27A provided in the mounting angle 25 (fourth step S4). By tightening the fixing screws 33, as shown in Figure 17, the rear surface 32F of the angle fixing part 32 comes into contact with the front surface 27B of the unit mounting part 27, and the HDD unit 1 is attached to the rack 2.

[0042] [Effects of the Embodiment] According to the equipment mounting bracket 3 and the method for mounting the HDD unit 1 to the rack 2 using the equipment mounting bracket 3 of this embodiment, the connecting member 30 that connects the HDD unit 1 and the mounting angle 25 of the rack 2 has a fixing hole 32A through which a fixing screw 33 that is screwed into the mounting screw hole 27A of the mounting angle 25 is inserted, and a locking hole 32B through which the locking head 34B of a locking screw 34 that is screwed onto the mounting angle 25 is inserted.

[0043] Therefore, by inserting the locking head 34B of the locking screw 34 screwed onto the mount angle 25 into the locking hole 32B of the connecting member 30 attached to the HDD unit 1, and engaging the upper edge 32G of the connecting member 30 that forms the small hole 32D of the locking hole 32B with the locking screw 34, the HDD unit 1 can be temporarily held on the mount angle 25.

[0044] As a result, the worker installing the HDD unit 1 can attach the HDD unit 1 to the rack 2 by inserting the fixing screw 33 through the fixing hole 32A while the HDD unit 1 is temporarily held in place, screwing it into the mounting screw hole 27A of the unit mounting part 27, and fixing the connecting member 30 to the mounting angle 25. Therefore, one worker can install the HDD unit 1 to the rack 2.

[0045] In this case, the locking screw 34 screwed onto the mount angle 25 has an enlarged diameter shaft portion 34C between the locking screw portion 34A and the locking head portion 34B, so that the locking hole 32B can hook the angle fixing portion 32, which is inserted through the locking head portion 34B of the locking screw 34, onto the enlarged diameter shaft portion 34C. Furthermore, since the enlarged diameter shaft portion 34C is smaller than the diameter D4 of the locking head portion 34B, it is possible to prevent the angle fixing portion 32, which is hooked onto the enlarged diameter shaft portion 34C, from coming out on the front side of the locking screw 34.

[0046] Furthermore, in the connecting member 30, the locking hole 32B is provided on the lower end side below the fixing hole 32A in the angle fixing portion 32 which faces the unit mounting portion 27 of the mount angle 25 in the depth direction. Therefore, the connecting member 30, with the upper edge 32G forming the small hole portion 32D of the locking hole 32B locked to the locking screw 34, tilts due to the weight of the mounted HDD unit 1, and is slightly inclined so that the upper side is located further back than the lower side.

[0047] At this time, as the HDD unit 1 tilts due to its own weight, the upper end 32H of the angle fixing portion 32 of the connecting member 30 comes into contact with the unit mounting portion 27. Due to this tilt, the lower side of the connecting member 30, which is located below the fixing hole 32A, comes into contact with the surface 34D on the unit mounting portion 27 side at the locking head 34B of the locking screw 34. In other words, the upper end 32H of the connecting member 30 is restricted from moving inward by the unit mounting portion 27, and the lower side is restricted from moving forward by the locking head 34B of the locking screw 34.

[0048] Furthermore, the weight of the HDD unit 1 causes the upper end of the connecting member 30 to press the unit mounting portion 27 inward, and the lower end of the connecting member 30 to press the locking head 34B inward, thereby temporarily holding the HDD unit 1 in a more stable position. For this reason, by simply inserting the locking head 34B through the locking hole 32B and locking the connecting member 30 with the locking screw 34, the upper side of the connecting member 30 is tilted so that it is positioned further back than the lower side, making it possible to temporarily hold the HDD unit 1 in a stable position.

[0049] As a result, the worker installing the HDD unit 1 can release their hands from the temporarily held HDD unit 1, and can use both hands to insert the fixing screw 33 through the fixing hole 32A and screw it into the mounting angle 25, thereby fixing the HDD unit 1 to the mounting angle 25 by tightening it. In other words, the worker can perform the work alone. At this time, the worker does not need to hold the HDD unit 1 unstably with one hand while tightening the fixing screw 33. Therefore, it is possible to provide an equipment mounting device 3 and mounting method that allows a worker to easily install the HDD unit 1 into the rack 2 by themselves.

[0050] Furthermore, the locking screw 34 that secures the connecting member 30 can be screwed into the mounting screw hole 27A provided in the mounting angle 25 for tightening the fixing screw 33 to secure the connecting member 30. Therefore, there is no need to use a special component to secure the connecting member 30. For this reason, by using a stepped screw as the locking screw 34, it is possible to reduce costs.

[0051] In the above embodiment, an example in which a stepped screw is used as the locking screw 34 has been described, but it is not limited to this. For example, a screw that does not have an enlarged shaft portion similar to the fixing screw 33 may be used as the locking screw, and the screw may be screwed in with a gap between the screw head and the unit mounting portion 27 in the depth direction, and the connecting member 30 may be locked to the screw portion that protrudes toward the front from the unit mounting portion 27.

[0052] [Modified example of connecting member 30] In the above embodiment, a connecting member 30 having two fixing holes 32A and two locking holes 32B in the angle fixing portion 32 was described as an example, but it is not limited to this. For example, as shown in Figures 18 to 20, the connecting member 30 may have a configuration in which one locking hole 32B is in the center in the vertical direction of the angle fixing portion 32, and fixing holes 32A above and below the locking hole 32B.

[0053] In this case, fixing holes 32A similar to the fixing holes 32A in the above embodiment are provided on the upper and lower ends of the angle fixing portion 32. The locking hole 32B has an enlarged portion 32C in the center that is larger than the diameter D4 of the locking head 34B of the locking screw 34, and small holes 32D, which are smaller than the diameter D4 of the locking head 34B of the locking screw 34 but larger than the diameter D5 of the enlarged shaft portion 34C, are connected above and below the enlarged portion 32C. For this reason, when the connecting member 30 is attached to the left panel 1C and the right panel 1D of the HDD unit 1, the small holes 32D are positioned above the enlarged portion 32C in both cases.

[0054] Then, when mounting the HDD unit 1 to the rack 2, the connecting member 30, which has one locking hole 32B, is pre-attached to the HDD unit 1 to the rack 2 (first step S1). First, the worker screws the locking screws 34 into the mounting screw holes 27A on the left and right mounting angles 25 that correspond to the positions where the HDD unit 1 is to be mounted (second step S2).

[0055] Next, the worker inserts the HDD unit 1 from the rear panel 1B side, through the two front vertical frames 23 that make up the rack 2, toward the rear. Then, as shown in Figure 19, after inserting the locking head 34B of the locking screw 34 into the enlarged hole 32C of the locking hole 32B of the left and right connecting members 30 attached to the HDD unit 1, the worker moves the HDD unit 1 downward and, as shown in Figure 20, hooks the upper edge 32G that forms the small hole 32D of the locking hole 32B of the connecting member 30 onto the enlarged diameter shaft 34C of the locking screw 34 to lock the connecting member 30 (third step S3).

[0056] Next, the worker inserts the fixing screws 33 through the two fixing holes 32A provided in the left and right connecting members 30 and tightens them into the mounting screw holes 27A provided in the mounting angle 25 to fix the connecting members 30 (fourth step S4).

[0057] Furthermore, by performing the above-described steps 1 S1 to 4 S4 in reverse order, it becomes possible to remove the HDD unit 1 attached to the rack 2. Specifically, first, the fixing screws 33 that secure the HDD unit 1 attached to the rack 2 are removed, leaving the connecting member 30 attached to the HDD unit 1 hooked onto the locking screws 34.

[0058] Next, after moving the HDD unit 1 upwards, pulling it towards the front allows the locking head 34B of the locking screw 34 to pass through the locking hole 32B of the connecting member 30, making it possible to remove the HDD unit 1. After that, the locking screw 34 and the connecting member 30 are removed as appropriate.

[0059] In this way, even when removing HDD unit 1 which is mounted on rack 2, one worker can perform the task, thus reducing the number of people required.

[0060] Although various embodiments have been described above with reference to the drawings, it goes without saying that this disclosure is not limited to such examples.
