[0014] An embodiment of the invention is described below. As can be seen from FIGS. 1 and 2 , a protective plate support member 1 of this embodiment is capable of supporting a protective plate 92 used to cover at least a portion of a conductive portion of a power distribution device 91. This protective plate support member 1 includes a fixed member 2 fixed to a fixed location and a movable member 5 that can be slid relative to the fixed member 2 and moved in the vertical direction. By sliding the movable member 5, the combined vertical length of the fixed member 2 and the movable member 5 can be changed from a first length to a second length. The fixed member 2 and the movable member 5 can be fixed in a state where the combined vertical length of the fixed member 2 and the movable member 5 is the first length, and the fixed member 2 and the movable member 5 can be fixed in a state where the combined vertical length of the fixed member 2 and the movable member 5 is the second length. This allows the protective plate support member 1 to have an adjustable support height.

[0015] 1 to 3, the protective plate support member 1 of the embodiment includes a fixed member 2 that is fixed to a fixed location, and a movable member 5 that is slidable relative to the fixed member 2. The fixed member 2 and the movable member 5 are used in combination, and the length between the end of the fixed member 2 and the end of the movable member 5 is adjusted so that the protective plate 92 can be supported under suitable conditions.

[0016] The fixing member 2 of the embodiment has a hollow cylindrical portion, which reduces its weight. Furthermore, the fixing member 2 of the embodiment has two notches 61 extending from the end to allow part of one surface of the square cylindrical portion to be elastically deformed (see FIG. 3). The portion located between these two notches 61 is used for elastic deformation (see FIG. 4).

[0017] The vertical length of the protection plate support member 1 can be changed by moving the movable member 5 combined with the fixed member 2 closer to or farther away from the bottom surface 23 of the fixed member 2. The movable member 5 shown in Figures 1 to 3 can slide along the outer peripheral surface of the fixed member 2, and a portion of the fixed member 2 is inserted inside the movable member 5. However, this is not a limitation. For example, the movable member 5 may be slidable along the inner peripheral surface of the fixed member 2. Furthermore, the fixed member 2 may be cylindrical rather than rectangular.

[0018] When the position of the movable member 5 is adjusted by sliding it against the fixed member 2, the positional relationship between the movable member 5 and the fixed member 2 can be maintained at the position after movement. Various means can be used to maintain the positional relationship between the movable member 5 and the fixed member 2. In this embodiment, the positional relationship can be maintained by engaging the movable member 5 and the fixed member 2.

[0019] In this embodiment, the movable member 5 is configured to be restrained from moving both upward and downward relative to the fixed member 2. In addition, the movable member 5 is provided with a portion that mainly restrains the movable member 5 from moving upward relative to the fixed member 2, and a portion that mainly restrains the movable member 5 from moving downward relative to the fixed member 2. This makes it easier to effectively restrain movement.

[0020] 3 to 6, the fixed member 2 is provided with a first engaging portion 21 engageable with the movable member 5 and a second engaging portion 22 engageable with the movable member 5. The movable member 5 is also provided with a first engaged portion 51 engageable with the first engaging portion 21 and a second engaged portion 52 engageable with the second engaging portion 22. The ability to suppress upward movement of the movable member 5 by engagement between the first engaging portion 21 and the first engaged portion 51 and the ability to suppress upward movement of the movable member 5 by engagement between the second engaging portion 22 and the second engaged portion 52 are both higher when either of these engagements is achieved. Furthermore, the ability to suppress downward movement of the movable member 5 by engagement between the first engaging portion 21 and the first engaged portion 51 and the ability to suppress downward movement of the movable member 5 by engagement between the second engaging portion 22 and the second engaged portion 52 are both higher when either of these engagements is achieved. Therefore, even if a force in the vertical direction is applied to the protection plate support member 1 due to shaking in the vertical direction or the like, it is possible to prevent the movable member 5 from moving relative to the fixed member 2.

[0021] In the embodiment, the engagement between the first engaging portion 21 and the first engaged portion 51 results in different levels of ability to suppress upward movement of the movable member 5 and different levels of ability to suppress downward movement. Also, the engagement between the second engaging portion 22 and the second engaged portion 52 results in different levels of ability to suppress upward movement of the movable member 5 and different levels of ability to suppress downward movement. It is possible to make either one or both of these have the same level of ability, but the configuration described above is preferable.

[0022] To achieve this, in the embodiment, the first engagement portion 21 has a claw-shaped first claw portion 211. The first claw portion 211 shown in FIGS. 3 and 4 has a claw-shaped first claw portion 211 protruding obliquely upward, with the angle formed by the lower surface of the first claw portion 211 relative to a plane perpendicular to the vertical direction being larger than the angle formed by the upper surface of the first claw portion 211 relative to a plane perpendicular to the vertical direction. The second engagement portion 22 has a claw-shaped second claw portion 221. The second claw portion 221 shown in FIGS. 3 and 5 has a claw-shaped second claw portion 221 protruding obliquely downward, with the angle formed by the lower surface of the second claw portion 221 relative to a plane perpendicular to the vertical direction being smaller than the angle formed by the upper surface of the first claw portion 211 relative to a plane perpendicular to the vertical direction. In the embodiment, a plurality of first claw portions 211 and a plurality of second claw portions 221 are provided and aligned in the vertical direction. Of course, the first claw portion 211 may face obliquely downward, and the second claw portion 221 may face obliquely upward.

[0023] In this embodiment, the first engaged portion 51 and the second engaged portion 52 have corresponding claw-shaped portions, which face obliquely downward or obliquely upward, respectively (see FIGS. 4 to 6).

[0024] In any case, it is preferable that the protective plate support member 1 be configured so that the engagement between the first engaging portion 21 and the first engaged portion 51 can suppress downward or upward movement of the movable member 5 that cannot be suppressed by the engagement between the second engaging portion 22 and the second engaged portion 52, and that the engagement between the second engaging portion 22 and the second engaged portion 52 can suppress upward or downward movement of the movable member 5 that cannot be suppressed by the engagement between the first engaging portion 21 and the first engaged portion 51.

[0025] The first engagement portion 21 and the second engagement portion 22 may be located in any position, but it is preferable to configure the second engagement portion 22 to be located to the right or left of the first engagement portion 21, as this makes it possible to ensure an adjustment range while reducing the length required in the vertical direction of the protective plate support member 1.

[0026] In the embodiment, an operating portion 71 is provided so as to be able to release the engagement between the first engaging portion 21 and the first engaged portion 51 and the engagement between the second engaging portion 22 and the second engaged portion 52. In the example shown in Fig. 3, the operating portion 71 is provided on the fixing member 2, and by pressing the operating portion 71 and moving it inward, it is possible to release both the engagement between the first engaging portion 21 and the first engaged portion 51 and the engagement between the second engaging portion 22 and the second engaged portion 52.

[0027] It should be noted that the operating unit 71 does not necessarily have to be provided on the fixed member 2, but may be provided on the movable member 5. Furthermore, it is not necessary to be able to release both the engagement between the first engaging portion 21 and the first engaged portion 51 and the engagement between the second engaging portion 22 and the second engaged portion 52 by simply operating one operating unit 71. As can be seen from Fig. 7, the operating unit 71 that releases the engagement between the first engaging portion 21 and the first engaged portion 51 and the operating unit 71 that releases the engagement between the second engaging portion 22 and the second engaged portion 52 may be provided in different locations.

[0028] 7, the first engaging portion 21 and the second engaging portion 22 are provided on opposing surfaces, and correspondingly, the first engaged portion 51 and the second engaged portion 52 are provided on opposing surfaces. Of course, they may not be provided on opposing surfaces. In other words, they may be provided on different surfaces.

[0029] As can be understood from these descriptions, it is preferable to provide the operating portion 71 on either the fixed member 2 or the movable member 5, and to configure the operating portion 71 so that by pressing and moving it inward, it is possible to release both the engagement between the first engaging portion 21 and the first engaged portion 51 and the engagement between the second engaging portion 22 and the second engaged portion 52.

[0030] Furthermore, when either the fixed member 2 or the movable member 5 is provided with an operating unit 71 that can be pressed and moved inward to release both the engagement between the first engaging portion 21 and the first engaged portion 51 and the engagement between the second engaging portion 22 and the second engaged portion 52, it is preferable to provide the first engaging portion 21 on one side in the left-right direction of the operating unit 71 and the second engaging portion 22 on the other side in the left-right direction of the operating unit 71. With this configuration, both the first engaging portion 21 and the second engaging portion 22 can be moved in a balanced manner by operating the operating unit 71 in one place.

[0031] 1 to 3, the movable member 5 is provided with a slide hole 72. The slide hole 72 in this example is a through-hole into which the operating portion 71 is inserted (see FIG. 8), and allows the positions of the operating portion 71 and the slide hole 72 to change as the height is adjusted. In this example, when it is desired to release the restriction on the movement of the movable member 5 due to the engagement between the first engaging portion 21 and the first engaged portion 51, the portion of the operating portion 71 that protrudes from the slide hole 72 can be pushed in.

[0032] If the operating unit 71 is configured to be inserted into the slide hole 72, the movement range of the operating unit 71 can be limited. This is because if the operating unit 71 is pushed in until it does not protrude from the slide hole 72, it becomes difficult to push the operating unit 71 in further. Therefore, it is possible to prevent the operating unit 71 from being pushed in too far. Note that when the operating unit 71 is provided on the movable member 5, the fixed member 2 may be provided with the slide hole 72.

[0033] Since it is possible to ensure an adjustment range while suppressing the length required in the vertical direction of the protection plate support member 1, it is preferable to provide the first engaging portion 21 or the first engaged portion 51 on one side of the left and right direction of the slide hole 72, and the second engaging portion 22 or the second engaged portion 52 on the other side of the left and right direction of the slide hole 72. In addition, it is preferable that the movable member 5 be slidable with the operating portion 71 inserted into the slide hole 72.

[0034] As can be understood from these descriptions, it is preferable that the protective plate support member 1 has a slide hole 72 in the movable member 5 or fixed member 2 on the side not provided with the operating part 71, a first engaging part 21 or a first engaged part 51 on one side of the left-right direction of the slide hole 72, and a second engaging part 22 or a second engaged part 52 on the other side of the left-right direction of the slide hole 72, so that the movable member 5 can be slidably moved when the operating part 71 is inserted into the slide hole 72.

[0035] The protective plate support member 1 is used to support a protective plate 92 that makes it difficult to access conductive parts of a power distribution device 91, such as a breaker. For this reason, the fixed member 2 of the embodiment has an insertion hole 24 on the bottom surface 23 so that it can be fixed to a fixed location (see FIG. 8 ). The fixed member 2 can be fixed to a desired location by passing a male screw or the like through the insertion hole 24. In the protective plate support member 1 of the embodiment, the fixed member 2 and the movable member 5 can be separated. Therefore, by removing the movable member 5 from the fixed member 2, a male screw can be passed through the insertion hole 24 with the head of the male screw positioned inside the fixed member 2.

[0036] In the example shown in Fig. 9, a protection plate support member 1 with the shortest vertical length is attached to a bus bar 93 connected to a breaker. The protection plate support member 1 and protection plate 92 are fixed together using screws. To make this possible, the protection plate support member 1 shown in Fig. 1 has a hole 53 on the top of the movable member 5. In this example, the hole 53 has a female thread, which makes it easy to attach a screw.

[0037] In the example shown in Figures 10 and 11, the protection plate support member 1 is attached with a slightly longer length in the vertical direction. In this example, multiple first claws 211 and multiple second claws 221 are provided and arranged in the vertical direction, so the vertical height can be set in stages. This makes it easier to unify the heights of multiple protection plate support members 1 compared to a stepless system. Note that the protection plate support member 1 in the example shown in Figure 12 can be moved up and down by rotating the movable member 5 along the screw thread, and this structure makes it a stepless system.

[0038] The protection plate support members 1 may be connected in the vertical direction (see Figure 13). In this example, the protection plate support members 1 are fixed together using screws. Of course, three or more protection plate support members 1 may be connected in the vertical direction or in the horizontal direction.

[0039] While the present invention has been described above using the embodiments as examples, the present invention is not limited to the above embodiments and can be embodied in various forms. For example, the positional relationship between the movable member and the fixed member may be maintained using screws. [Explanation of symbols]
