As shown in FIG. 2, the equipment panel 1 includes a breaker 90 and control devices 98 and 99 inside the housing 10. The control devices 98 and 99 may be power distribution devices or power distribution devices.

  In the following description, the front direction is a direction perpendicular to the back surface 19 (see FIG. 2) of the housing 10 and is directed from the back surface 19 to the first sub door 20 (or the master door 30 and the second sub door 26). Direction. The rear direction is a direction from the first sub door 20 (or the master door 30 and the second sub door 26) toward the back surface 19. In the drawing, the forward direction is shown as the positive direction of the x axis, and the backward direction is shown as the negative direction of the x axis. Also, the vertical direction and the horizontal direction viewed from the person standing on the floor where the equipment panel 1 is installed with the face facing forward (the positive direction of the x axis) are defined as the vertical direction and the horizontal direction, respectively. To do. In the drawing, the upward direction is shown as the positive direction of the y axis, and the downward direction is shown as the negative direction of the y axis. Further, the left direction is shown as the positive direction of the z axis, and the right direction is shown as the negative direction of the z axis.

  The master door 30, the first sub door 20, and the second sub door 26 are arranged side by side. In the drawing, an example in which the master door 30, the first sub door 20, and the second sub door 26 are arranged in order from the left is shown. In the following description, the first sub door 20, the master door 30, and the second sub door 26 may be referred to as a first door, a second door, and a third door, respectively. The housing 10 includes a first upper flange 11, a first lower flange 12, a second upper flange 13, and a second lower flange 14. The first upper flange 11 and the second upper flange 13 are surfaces that protrude downward from the ceiling of the housing 10. The first lower flange 12 and the second lower flange 14 are surfaces that protrude upward from the bottom surface of the housing 10. The first upper flange 11 and the first lower flange 12 face the first sub door 20 when the first sub door 20 is closed, and overlap the first sub door 20 in a front view. The second upper flange 13 and the second lower flange 14 face the master door 30 when the master door 30 is closed, and overlap the master door 30 in a front view.

  The first handle 21 and the first door hinge 23 are provided on the first sub door 20. The first sub door 20 is rotated by the first door hinge 23. The first sub door 20 is locked or unlocked by the rotation of the first handle 21. The first handle 21 is provided with a handle extending in the radial direction of the rotation shaft of the first handle 21 so that the first handle can be easily rotated by the operator's hand. The first sub door 20 is provided with a sub door lock mechanism 50. FIG. 3 is a rear view of the first sub door 20. Referring to FIG. 3, the sub door lock mechanism 50 includes a first crank arm 51, a first locking bar 52, a second locking bar 53, a first bar guide 54, a second bar guard 55, a first roller 56, 2 rollers 57 are included. A flat plate-like first crank arm 51 is attached to the handle shaft 21 a of the first handle 21. A first locking bar 52 extending upward and a second locking bar 53 extending downward are attached to both ends of the first crank arm 51. That is, the first locking bar 52 and the second locking bar 53 are installed on the first sub door 20.

  The first locking bar 52 is rotatably attached to the first crank arm 51 via a joint J1. The first locking bar 52 is preferably a rod-shaped member. The first locking bar 52 is supported by the first bar guide 54. As the first locking bar 52 is guided by the first bar guide 54, the first locking bar 52 moves up and down in accordance with the rotation of the first handle 21 (first crank arm 51). Specifically, when the first sub door 20 is locked by the first handle 21, the first locking bar 52 rises. When the first sub door 20 is unlocked by the first handle 21, the first locking bar 52 is lowered. A first roller 56 is provided at the upper end of the first locking bar 52. The first roller 56 moves up and down as the first locking bar 52 moves up and down.

  When the first sub door 20 is locked by the first handle 21, the first roller 56 contacts the rear surface of the first upper flange 11 of the housing 10 (see FIGS. 1 and 6A). Accordingly, when the first sub door 20 is locked by the first handle 21, the first roller 56 is caught on the rear surface of the first upper flange 11 of the housing 10, so that the operator cannot open the first sub door 20. FIG. 4 shows a state in which the first sub door 20 is unlocked by the first handle 21. Referring to FIGS. 3 and 4, when the first sub door 20 is unlocked by the first handle 21, the first roller 56 is positioned below the first upper flange 11 of the housing 10. For this reason, when the 1st subdoor 20 is unlocked by the 1st handle 21, since the 1st roller 56 does not catch on the rear surface of the 1st upper flange 11 of case 10, an operator opens the 1st subdoor 20. Can do.

  The second locking bar 53 is attached to the first crank arm 51 so as to be rotatable via a joint J2. The second locking bar 53 is preferably a rod-shaped member. The second locking bar 53 is supported by the second bar guide 55. When the second locking bar 53 is guided by the second bar guide 55, the second locking bar 53 moves up and down in accordance with the rotation of the first handle 21 (first crank arm 51). Specifically, when the first sub door 20 is locked by the first handle 21, the second locking bar 53 is lowered. When the first sub door 20 is unlocked by the first handle 21, the second locking bar 53 is raised. A second roller 57 is provided at the lower end of the second locking bar 53. The second roller 57 moves up and down as the second locking bar 53 moves up and down.

  When the first sub door 20 is locked by the first handle 21, the second roller 57 contacts the rear surface of the first lower flange 12 of the housing 10 (see FIG. 1). Accordingly, when the first sub door 20 is locked by the first handle 21, the second roller 57 is caught on the rear surface of the first lower flange 12 of the housing 10, so that the operator cannot open the first sub door 20. 3 and 4, when the first sub door 20 is unlocked by the first handle 21, the second roller 57 is positioned above the first lower flange 12 of the housing 10. For this reason, when the 1st subdoor 20 is unlocked by the 1st handle 21, since the 2nd roller 57 does not catch on the rear surface of the 1st lower flange 12 of case 10, an operator opens the 1st subdoor 20. Can do.

  The second sub door 26 is disposed adjacent to the first sub door 20. The second sub door 26 is also provided with a third door hinge 27, and the second sub door 26 is rotated by the third door hinge 27. As shown in FIG. 2, the left end 28 of the second sub door 26 is located directly behind the right end 24 of the first sub door 20. For this reason, the operator cannot open the second sub door 26 unless the first sub door 20 is opened.

  Similarly to the first sub door 20, the master door 30 is also provided with a second handle 31 and a second door hinge 33. A master door lock mechanism 70 is provided on the back side of the master door 30 opposite to the front side of the master door 30 to which the second handle 31 is attached. The master door lock mechanism 70 includes a second crank arm 71, a third locking bar 72, a fourth locking bar 73, a third bar guide 74, a fourth bar guard 75, a third roller 76, and a fourth roller 77. Second handle 31, second door hinge 33, second crank arm 71, third locking bar 72, fourth locking bar 73, third bar guide 74, fourth bar guard 75, third roller 76, and fourth roller 77 Are the first handle 21, the first door hinge 23, the first crank arm 51, the first locking bar 52, the second locking bar 53, the first bar guide 54, the second bar guard 55, the first roller 56, and Since it has the same structure and function as the second roller 57, a detailed description is omitted.

  Referring to FIG. 1, when the master door 30 is locked by the second handle 31, the third roller 76 contacts the rear surface of the second upper flange 13 of the housing 10. Further, when the master door 30 is unlocked by the second handle 31, the third roller 76 is positioned below the second upper flange 13 of the housing 10. Referring to FIG. 1, when the master door 30 is locked by the second handle 31, the fourth roller 77 contacts the rear surface of the second lower flange 14 of the housing 10. Further, when the master door 30 is unlocked by the second handle 31, the fourth roller 77 is positioned above the second lower flange 14 of the housing 10.

  As shown in FIG. 1, the master door 30 further has an opening 32 so that the external operation handle 92 of the breaker 90 can be operated from the front side of the master door 30. Therefore, the external operation handle 92 is located inside the outer shape of the master door 30 in the front view. 1 and 2, the breaker 90 is attached to a bracket 19 that protrudes forward from the back surface 19 of the housing 10. The breaker 90 is located on the inner side (rear side) of the master door 30. FIG. 4 shows the equipment panel in a state where the master door is open. According to this, the breaker 90 includes the external operation handle 92 and the release screw 93 protruding from the breaker body 91 toward the front (master door 30). The breaker body 91 has openings in the left-right direction or the front-rear direction. An operation handle 96 (details will be described later) of the breaker main body 91 and an external member can be connected.

  FIG. 5A is an enlarged view of the external operation handle 92 and the release screw 93 of the breaker 90. As shown in FIG. 5, ON / OFF / TRIP / RESET is designated according to the rotation angle of the external operation handle 92. The ON state of the breaker 90 means a state in which electricity is sent to the control devices 98, 99 and the like. The breaker 90 is in an OFF state refers to a state in which the power supply of the entire device panel including the breaker 90, such as the control devices 98 and 99, is OFF. The state in which the breaker 90 is in the TRIP state refers to a state in which the power to the breaker 90 is turned on but electricity is not sent to the control devices 98, 99 and the like. When the breaker 90 is in the RESET state, the master door 30 can be opened and closed in addition to the OFF state described above. That is, when the breaker 90 is in the ON / OFF / TRIP state, the master door 30 is doubly locked in addition to the lock by the second handle 31 by the engaging part (not shown) of the breaker 90. However, when the breaker 90 is in the RESET state, the above-described lock of the master door 30 is released, so that the operator can open the master door 30.

  FIG. 5B shows an operation handle 96 provided on the breaker body 91. The operation handle 96 moves up and down as shown in the figure in conjunction with the direction of the external operation handle 92. That is, when “OFF” or “RESET” is set by the external operation handle 92, the operation handle 96 points to the lowest “OFF position”. Further, when “ON” is set by the external operation handle 92, the operation handle 96 indicates the uppermost “ON position”. When “TRIP” is set by the external operation handle 92, the operation handle 96 indicates a “TRIP position” located between the “ON position” and the “OFF position”. FIG. 5B shows a state where the external operation handle 92 points to the “ON position”.

  The release screw 93 is a member that performs a setting to release the lock of the master door 30 by the breaker 90 by operating the engaging part of the breaker 90 when the breaker 90 is in the ON / OFF / TRIP state. The release screw 93 is normally set in the direction of LOCK in FIG. When the release screw 93 is rotated in the direction of UNLOCK in FIG. 5A, the master door 30 is unlocked by the breaker 90 even if the breaker 90 is in the ON / OFF / TRIP state. That is, the operator can open the master door 30 even when the breaker 90 is in the ON / OFF / TRIP state. On the other hand, when the release screw 93 is rotated in the direction of LOCK in FIG. 5A, the locking component of the breaker 90 returns to the normal position. That is, when the breaker 90 is in the ON / OFF / TRIP state, the master door 30 is locked by the breaker 90.

  As shown in FIGS. 1, 2, and 4, the equipment panel 1 includes an interlock mechanism 80 as its door structure. The interlock mechanism 80 locks / unlocks the first sub door 20 in conjunction with opening / closing of the master door 30. The interlock mechanism 80 includes the sliding rod 40, the first pressing mechanism 82, the fifth roller 83, the handle catch 49, the sliding rod guide 35, and the suspension member 100.

  The sliding rod 40 is a rod-shaped member that extends in the left-right direction. The sliding rod 40 extends from a position behind the master door 30 (position of the fifth roller 83) to a position behind the second sub door 26 (position of a first flange 41 described later). The sliding rod 40 is supported by a first support member 16 and a second support member 17 that extend downward from the ceiling of the housing 10. For this reason, the sliding rod 40 is arranged in the horizontal direction. The sliding rod 40 includes a first flange 41 and a second flange 42. The first pressing mechanism 82 is disposed between the second flange 42 and the second support member 17. The first pressing mechanism 82 is typically a spring, but may be any member that can expand and contract, such as rubber.

  The fifth roller 83 is provided at the tip 44 located inside the master door 30 (the rear side when the master door 30 is closed) of the two tips of the sliding rod 40. The sliding rod guide 35 is provided above the master door 30 and inside the master door 30. That is, the master door 30 includes a sliding rod guide 35. As shown in FIG. 2, the sliding rod guide 35 includes a curved first contact surface 35 a for contacting the fifth roller 83.

  The first pressing mechanism 82 presses the fifth roller 83 against the sliding rod guide 35 until the master door 30 opens from the closed state to a predetermined angle. 1 and 2 show the positions of the fifth roller 83 and the sliding rod 40 and the state of the first pressing mechanism 82 when the master door 30 is closed. At this time, the first pressing mechanism 82 is most contracted. FIG. 4 shows the positions of the fifth roller 83 and the sliding rod 40 and the state of the first pressing mechanism 82 in a state where the master door 30 is completely opened. At this time, the fifth roller 83 is not in contact with the sliding rod guide 35, and the first pressing mechanism 82 is extended until the first flange 41 is in contact with the first support member 16. As described above, when the master roller 30 is opened and closed, the fifth roller 83 moves on the sliding rod guide 35, so that the sliding rod 40 moves in the axial direction of the sliding rod 40. Note that the fifth roller 83, the sliding rod guide 35, and the first pressing mechanism 82 that move the sliding rod 40 in the axial direction of the sliding rod 40 are also referred to as a rod driving mechanism.

  The handle catch 49 is fixed to the sliding rod 40. Therefore, the position of the handle catch 49 moves in the left-right direction according to the position of the sliding rod 40 (the position of the fifth roller 83). As shown in FIGS. 1 and 2, the handle catch 49 is located directly below the suspension member 100 when the master door 30 and the first sub door 20 are locked. Further, as shown in FIGS. 3 and 4, the handle catch 49 is not located directly below the suspension member 100 in a state where the master door 30 is opened. However, since the sliding rod 40 moves in the axial direction (horizontal direction) of the sliding rod 40, the vertical relationship between the suspension member 100 and the handle catch 49 does not change if the first sub door 20 is locked. That is, when the first sub door 20 is locked, the suspension member 100 is positioned above the upper surface 49 a of the handle catch 49. In FIG. 2, the outer shape of the handle catch 49 in a state where the master door 30 is opened is indicated by a one-dot chain line.

  FIG. 6A shows a shape of the suspension member 100 and the handle catch 49 viewed from the side (left direction) in a state where the master door 30 and the first sub door 20 are locked. FIG.6 (b) has shown the shape which looked at the suspension member 100 from back in the same state as Fig.6 (a). Referring to FIGS. 6A and 6B, the suspension member 100 includes a first sliding surface 101, a bottom surface 102, a protrusion 103, a hinge 104, and an upper support portion 105. The hanging member 100 has a substantially triangular shape in a side view. In other words, the suspension member 100 has a substantially triangular prism shape. The suspension member 100 is swingable in the front-rear direction by the hinge 104. In FIG. 6, the rotation axis of the hinge 104 is indicated by Ax1. The suspension member 100 is supported by the shaft support member 110. The shaft support member 110 includes an L-shaped third support member 112 fixed to the first locking bar 52 and a bolt 111 screwed into the third support member 112. The third support member 112 has a thread groove 112 a corresponding to the thread groove of the bolt 111. Further, the upper support portion 105 has an insertion hole through which the bolt 111 is inserted. The upper support portion 105 is not fixed by the bolt 111 and is supported by the bolt 111 so as to be swingable in the left-right direction. That is, the suspension member 100 is swingable in the left-right direction. In FIG. 6, the rotation axis when the suspension member 100 swings is indicated by Ax2. The third support member 112 is provided near the first roller 56, that is, above the first locking bar 52. Therefore, the suspension member 100 is provided near the first roller 56, that is, above the first locking bar 52.

  FIG. 2 shows a view of the suspension member 100 not receiving an external force other than gravity as viewed from above. The handle catch 49 shown by a solid line and a dotted line in FIG. 2 is a handle in the state shown in FIG. Shows the catch. In other words, the rod driving mechanism described above moves the sliding rod 40 so that the bottom surface 102 of the suspension member 100 not receiving external force other than gravity and the upper surface 49a of the handle catch 49 overlap in a top view. Such a setting by the rod driving mechanism is called a first setting or an interlock setting. In FIG. 2, the setting in which the rod drive mechanism moves the handle catch to the position of the handle catch 49 indicated by the one-dot chain line is referred to as a second setting or an interlock-off setting. In the second setting, the rod driving mechanism moves the sliding rod 40 so that the bottom surface 102 of the suspension member 100 not receiving an external force other than gravity and the top surface 49a of the handle catch 49 do not overlap in top view. Whether the rod drive mechanism performs the first setting (interlock setting) or the second setting (interlock off setting) is determined by opening / closing the master door 30. In this way, a member capable of setting whether the first setting or the second setting is performed by the rod driving mechanism is referred to as a first setting member. Therefore, in the present embodiment, the first setting member is the master door 30.

  As shown in FIG. 6A, the handle catch 49 includes an upper surface 49a for contacting the bottom surface 102 of the suspension member 100 that is not subjected to an external force other than gravity. The bottom surface 102 of the suspension member 100 is preferably a flat surface, and the bottom surface 102 of the suspension member 100 not receiving an external force other than gravity forms a horizontal surface. Therefore, the upper surface 49a of the handle catch 49 is preferably a horizontal plane. The shape other than the upper surface 49a of the handle catch 49 may be any shape. From this state (in other words, the state in which the first sub door 20 is locked and the first setting is made by the rod drive mechanism), the first handle 21 is rotated in the direction in which the first sub door 20 is unlocked. When the suspension member 100 does not receive an external force other than gravity, the bottom surface 102 of the suspension member 100 comes into contact with the upper surface 49 a of the handle catch 49. Thereby, the rotation of the first handle 21 is prevented.

  The first sliding surface 101 is a surface for sliding with the first end portion 49 b of the handle catch 49. The first end 49b is preferably the front end of the handle catch 49. FIG. 7A shows the state of the suspension member 100 and the handle catch 49 immediately after the first sub door 20 is closed in the state where the master door 30 is closed (that is, the state where the first setting is made in the rod drive mechanism). Indicates the state. That is, in the state shown in FIG. 7A, the first sub door 20 is unlocked. At this time, the first sliding surface 101 is in contact with the first end 49b of the handle catch 49, and the suspension member 100 is inclined in the front-rear direction. More specifically, the suspension member 100 is inclined in the direction opposite to the handle catch 49 (forward direction). FIG. 7B shows a state of the suspension member 100 and the handle catch 49 after the first handle 21 is slightly rotated from the state of FIG. 7A in the direction in which the first sub door 20 is locked. Since the first sliding surface 101 is a flat surface as shown in FIG. 6, the first end 49 b slides with the first sliding surface 101 facing downward without being caught in the middle of the first sliding surface 101. It is moving. When the first sub door 20 is locked, the first end portion 49b is disengaged from the first sliding surface 101, and the suspension member 100 is rotated rearward as shown in FIG. As described above, when the first handle 21 is to be rotated in the direction in which the first sub door is locked after the first sub door 20 is unlocked, the first sliding surface 101 of the suspension member 100 is moved to the handle catch 49. The suspending member 100 is raised while sliding with the first end portion 49b.

  As shown in FIG. 8, the suspension member 100 preferably further includes a second sliding surface 106. FIG. 8A shows a state in which the master door 30 is opened (a state in which the second setting (interlock-off setting) is set in the rod drive mechanism), and the suspension member 100 immediately after the first sub door 20 is closed. The state of the handle catch 49 is shown. Fig.8 (a) is the figure which looked at the suspension member 100 and the handle catch 49 from the front. In the state shown in FIG. 8A, the first sub door 20 is unlocked. Referring to FIG. 8A, the second sliding surface 106 faces the second end portion 49c of the handle catch 49 in a state where the second setting is made in the rod driving mechanism. The second end portion 49 c is an end portion of the left and right ends of the handle catch 49 that faces the suspension member 100 in a state where the second setting is made in the rod drive mechanism. The second end 49c is, for example, the right end of the handle catch 49.

  FIG. 8B shows the suspension member 100 and the handle catch when the master door 30 is closed (when the first setting is made in the rod drive mechanism) with the first sub door 20 closed in an unlocked state. 49 states are shown. FIG. 8B is also a view of the suspension member 100 and the handle catch 49 as seen from the front. As shown in FIG. 7A, the handle catch 49 is lower than the hinge 104 even when the first sub door 20 is unlocked. Therefore, when the first setting is made in the rod drive mechanism after the first sub door is closed while being unlocked in the state where the second setting is made in the rod drive mechanism, the handle catch 49 is moved to the second slide. Abuts against the moving surface 106. Here, since the suspension member 100 is swingable also in the left-right direction, the suspension member 100 is inclined in the left-right direction. More specifically, the suspension member 100 is inclined in the direction opposite to the handle catch 49 (right direction). In this state, when the first handle 21 is rotated in the direction in which the first sub door 20 is locked, the rotation axis Ax2 rises vertically upward. That is, the suspension member 100 is lifted so that the normal line of the bottom surface 102 gradually approaches vertically downward while the second sliding surface 106 slides with the second end portion 49c. Here, as illustrated in FIG. 6B, the suspension member 100 includes a protrusion 103 that protrudes from the side surface of the suspension member 100 in at least one of the left and right directions. More specifically, when the side on which the handle catch 49 is located when the master door 30 is opened is the first side of the left side and the right side of the suspension member 100, the protrusion 103 is provided at least on the first side. However, as shown in FIG. 6A, the rear end 103 a of the protrusion 103 is positioned in front of the first end portion 49 b of the handle catch 49. Therefore, when the suspension member 100 is lifted from the state shown in FIG.

  As can be seen from the examples of FIGS. 7 and 8, even if the first sub door 20 is unlocked and the master door is closed (the first setting is performed by the rod driving member), the first sub door 20 is locked. Can be made.

  The first sub door 20 is provided with an interlock release mechanism. As shown in FIG. 6A, when the master door 30 is closed in a state where the first sub door 20 is locked, the bottom surface 102 of the suspension member 100 comes into contact with the upper surface 49a of the handle catch 49. Cannot be unlocked. The interlock release mechanism is a mechanism that moves the suspension member 100 so that the first sub door 20 can be unlocked even in such a state. Referring to FIG. 1, the interlock release mechanism includes a handle release screw 22 and an external force applying member 60. Referring to FIG. 3, the external force applying member 60 includes a third crank arm 61, a handle release bar 62, a release lever 63, and a release lever support member 64.

  Referring to FIG. 1, the handle release screw 22 is provided on the outer surface of the first sub door 20. The handle release screw 22 is freely rotatable. Referring to FIG. 3, a flat plate-like third crank arm 61 is attached to the rotation shaft 22 a of the handle release screw 22. The rotating shaft 22 a is located at one end of the third crank arm 61. A handle release bar 62 extending upward is attached to the other end of the third crank arm 61. The handle release bar 62 is rotatably attached to the third crank arm 61 via a joint J3. The handle release bar 62 is preferably a rod-shaped member. The handle release bar 62 is supported by a release lever 63.

  FIG. 9 is a diagram illustrating the function and detailed structure of the unlocking mechanism by enlarging the vicinity of the suspension member 100. Referring to FIG. 9, the handle release bar 62 is rotatably attached to an L-shaped release lever 63 via a joint J4. That is, the release lever 63 is rotatably connected to the upper end portion of the handle release bar 62. The release lever 63 is rotatably attached to the release lever support member 64 via a joint J4. That is, the release lever support member 64 supports the release lever 63 in a rotatable manner. The release lever 63 is disposed adjacent to the suspension member 100. The release lever 63 is provided on the left and right sides of the suspension member 100 on the side where the handle catch 49 is located when the master door 30 is opened. The release lever support member 64 is fixed to the back surface of the first sub door 20 (the surface located on the rear side of the first sub door 20 when the first sub door 20 is closed). Since the external force applying member 60 has such a structure, the first locking bar 52 is raised or lowered according to the rotation of the handle release screw 22.

  FIG. 9A shows the position and orientation of each component of the external force applying member 60 when normal setting is performed by the handle release screw 22. This normal setting is a setting that validates the first setting (interlock setting) by the rod drive mechanism. Such a setting is called an interlock effective setting. In the interlock effective setting, the release lever 63 does not apply force to the protrusion 103 of the suspension member 100. FIG. 9A shows a state in which the release lever 63 is separated from the protrusion 103, but the release lever 63 may be in contact with the protrusion 103.

  FIG. 9B shows the position and orientation of each component when the handle release screw 22 is set to release the first setting (interlock setting) by the rod drive mechanism. Such a setting is called an interlock release setting. In this case, the handle release bar 62 is raised by the rotation of the handle release screw 22 as compared to the handle release bar 62 when the interlock effective setting is performed. More specifically, the rotation of the handle release screw 22 raises the position of the joint J4 of the handle release bar 62 as compared to the position of the joint J4 of the handle release bar 62 when the interlock effective setting is performed. Therefore, the release lever 63 rotates clockwise about the joint J5 as a rotation axis. At this time, the release lever 63 hooks the protrusion 103 to rotate the suspension member 100 forward. That is, the release lever 63 (external force applying member 60) applies an external force other than gravity to the suspension member 100. As a result, the suspension member 100 is rotated so that the bottom surface 102 of the suspension member 100 is positioned in front of the first end portion 49 b of the handle catch 49. In other words, the release lever 63 (external force applying member 60) rotates the suspension member 100 to a position where the bottom surface 102 of the suspension member 100 and the handle catch 49 do not overlap when viewed from above.

  As described above, the handle release screw 22 can set whether or not to release the first setting (interlock setting) by the rod drive mechanism. Therefore, the handle release screw 22 is also referred to as a second setting member. The setting of the handle release screw 22 is determined by the angle of the handle release screw 22. That is, when the setting angle of the handle release screw 22 is set to a predetermined first angle, the handle release bar 62 is raised and the interlock release setting is performed. When the set angle of the handle release screw 22 is set to a predetermined second angle different from the first angle, the handle release bar 62 is lowered and the interlock effective setting is performed. Therefore, the handle release bar 62 moves up and down according to the setting of the handle release screw 22.

  When the interlock release setting is performed as described above, even if the first sub door 20 is closed in a state where the master door 30 is closed (that is, a state where the first setting is made in the rod drive mechanism). Unlike the example of FIGS. 7A and 7B, the first sliding surface 101 of the suspension member 100 does not contact the first end portion 49 b of the handle catch 49. Further, even when the master door 30 is closed with the first sub door 20 being unlocked and closed (when the first setting is made in the rod drive mechanism), it is different from the example of FIG. 8B. The second sliding surface 106 of the suspension member 100 does not contact the second end 49c of the handle catch 49.

  As described above, the door structure of the equipment panel 1 according to the first embodiment realizes an interlock function that prevents the first sub door 20 from being unlocked by the first handle 21 by opening and closing the master door 30. Further, depending on the configuration of the suspension member 100, the operator can lock the first sub door 20 regardless of whether the master door 30 is opened or closed. Further, the interlock release setting and the interlock release setting can be performed by the handle release screw 22. Therefore, the equipment panel 1 with high operator convenience is realized.

[Second Embodiment]
FIG. 10 is a front view of the equipment panel 1a according to the second embodiment. FIG. 11 is a cross-sectional view of the equipment panel 1a as seen from the section line XI-XI in FIG. The device panel 1a according to the second embodiment is common to the device panel 1 according to the first embodiment in many elements. Therefore, description of elements common to the device panel 1 is omitted. In the device panel 1a, instead of the fifth roller 83 and the sliding rod guide 35 of the device panel 1, a link mechanism 85, a first wire 86, a second wire 87, a first wire casing fixture 88, a wire casing 89, a second A wire casing fixture 95 and a breaker setting transmission mechanism 94 are included. The sliding rod 40 a has a third flange 43 instead of the second flange 42 of the sliding rod 40. The third flange 43 is provided on the right side of the second support member 17, that is, on the side far from the link mechanism 85 among the left side and the right side of the second support member 17. Between the 3rd flange 43 and the 2nd support member 17, it replaces with the 1st press mechanism 82 and the 2nd press mechanism 82a is arrange | positioned. The second pressing mechanism 82a may be made of the same material as the first pressing mechanism 82. The second pressing mechanism 82a presses the sliding rod 40a in a direction away from the link mechanism 85 in the axial direction of the sliding rod 40a (right direction). In the second embodiment, the link mechanism 85, the first wire 86, the second wire 87, the wire casing 89, and the second pressing mechanism 82a are referred to as a rod driving mechanism.

  FIG. 12 is a diagram illustrating a control state of the sliding rod 40a when the operation handle 96 of the breaker body 91 is set to the ON position. FIG. 13 is a diagram illustrating a control state of the sliding rod 40a when the operation handle 96 of the breaker body 91 is set to the OFF position.

  As shown in FIGS. 12 and 13, the breaker main body 91 operation handle 96 is provided with a breaker setting transmission mechanism 94. The breaker setting transmission mechanism 94 has an opening 94 a for engaging with the operation handle 96 inside the breaker setting transmission mechanism 94. The breaker setting transmission mechanism 94 is rotatably supported by the joint J8. The joint J8 is usually fixed to the breaker 90. For convenience of explanation, the rotation axis of the breaker setting transmission mechanism 94 is shown as Ax4. When the position of the operation handle 96 changes, the operation handle 96 pushes a boundary portion that forms the opening 94a, whereby the orientation of the breaker setting transmission mechanism 94 changes. The breaker setting transmission mechanism 94 includes a wire attachment boss 97 for attaching the second wire 87. That is, the second wire 87 is connected to the external operation handle 92 via the breaker setting transmission mechanism 94 and the operation handle 96.

  The second wire 87 slides inside the wire casing 89. The wire casing 89 is fixed inside the equipment panel 1a by the first wire casing fixing tool 88 and the second wire casing fixing tool 95. Specifically, the first wire casing fixture 88 is fixed to the fourth support member 18 extending downward from the ceiling of the housing 10. The second wire casing fixture 95 is fixed to the breaker 90. Therefore, the path of the wire casing 89 between the breaker 90 and the fourth support member 18 is fixed by the first wire casing fixture 88 and the second wire casing fixture 95. The fourth end J6 of the second wire 87 located on the opposite side of the third end attached to the wire attachment boss 97 of the second wire 87 is connected to the link mechanism 85.

  The first wire 86 is connected to the tip 44 of the sliding rod 40a. The sixth end J5 of the first wire 86 located on the opposite side of the fifth end attached to the tip 44 of the sliding rod 40a of the first wire 86 is connected to the link mechanism 85. That is, the link mechanism 85 is connected to the first wire 86 and the second wire 87 together. The link mechanism 85 is rotatably supported by the joint J7. The joint J7 is fixed to the fourth support member 18. For convenience of explanation, the rotation axis of the fourth support member 18 is shown as Ax3.

  As shown in FIG. 12, when the operation handle 96 is set to the ON position, the breaker setting transmission mechanism 94 faces obliquely upward. At this time, the sliding rod 40a is pushed by the second pressing mechanism 82a and moves rightward (in a direction away from the link mechanism 85). In this case, the interlock setting described above is performed. That is, when the breaker 90 is set to ON by the external operation handle 92, the first setting is performed by the rod driving mechanism.

  As shown in FIG. 13, when the operation handle 96 is set to the OFF position, the breaker setting transmission mechanism 94 faces obliquely downward. At this time, when the second wire 87 pulls the link mechanism 85, the link mechanism 85 rotates clockwise. As a result, the first wire 86 is pulled in the left direction, and the sliding rod 40a moves in the left direction (direction approaching the link mechanism 85). As a result, the handle catch 49 is moved to the position of the one-dot chain line in FIG. Therefore, the interlock-off setting described above is performed. That is, when the breaker 90 is set to OFF or RESET by the external operation handle 92, the second setting is performed by the rod driving mechanism.

  As described above, it is possible to set whether to perform the interlock setting or the interlock off setting by the operation handle 96 and the external operation handle 92 that moves the operation handle 96. Therefore, in the second embodiment, the external operation handle 92 and the operation handle 96 correspond to the first setting member described above.

  As described above, in the door structure of the equipment panel 1a according to the second embodiment, the interlock setting and the interlock off setting can be performed based on the output of the operation handle 96 of the breaker 90. Therefore, the safety of the equipment panel 1a is further improved.

[Feature]
The features of the door structure of the equipment panel 1, 1a according to the above-described embodiment are as follows. According to the door structure, whether the interlock setting (first setting) or the interlock-off setting (second setting) is set by the master door 30 or the external operation handle 92 of the breaker 90 is set. . When the interlock setting is performed by the rod driving mechanism, the sliding rods 40 and 40a are moved so that the bottom surface 102 of the suspension member 100 and the top surface 49a of the handle catch 49 overlap in the top view. Therefore, the door structure of the equipment panel 1, 1a in which the first sub door 20 is locked according to the setting or operation of the equipment panel 1, 1a other than the first handle 21 of the first sub door 20 is realized.

  The suspension member 100 includes a first sliding surface 101 for sliding with the first end 49 b of the handle catch 49. When the first sub door 20 is closed with the interlock setting in the rod drive mechanism, the first end portion 49b comes into contact with the first sliding surface 101 and the suspension member 100 is inclined in the front-rear direction. When the first handle 21 is to be rotated in the direction in which the first sub door 20 is locked, the suspension member 100 is raised while the first sliding surface 101 slides with the first end portion 49b. Accordingly, even when the hanging member 100 is not located above the handle catch 49 when the first sub door 20 is closed, the hanging member 100 can be moved above the handle catch 49.

  The door structure further includes a handle release screw 22 and an external force applying member 60. Whether or not to release the interlock setting by the rod drive mechanism can be set by the handle release screw 22. When the external force imparting member 60 is set to release the interlock setting by the handle release screw 22, an external force other than gravity is applied to the suspension member 100, and the bottom surface 102 of the suspension member 100 and the handle catch 49 overlap in a top view. The suspension member 100 is rotated to the position where it does not. Accordingly, even when the suspension member 100 is above the handle catch 49, the first handle 21 can be rotated in the direction in which the first sub door 20 is unlocked.

The suspension member 100 can swing in the left-right direction. The hanging member 100 may further include a second sliding surface 106. The second sliding surface 106 may be opposed to the second end portion 49c of the handle catch 49 in a state where the interlock driving is set in the rod driving mechanism. When the interlock is set in the rod drive mechanism after the first sub door 20 is closed while being unlocked in the state where the interlock drive is set in the rod drive mechanism, the second end portion 49c is moved to the second sliding position. The suspension member 100 is tilted in the left-right direction in contact with the surface 106. Thereby, even if the sliding rods 40 and 40a move in the axial direction and the handle catch 49 collides with the side surface of the suspension member 100, the influence of the suspension member 100 due to the force caused by the collision is reduced, and such a state However, the first handle can be rotated in the direction in which the first sub door 20 is unlocked.

  In the first embodiment, the rod driving mechanism includes a fifth roller 83, a sliding rod guide 35, and a first pressing mechanism 82. The fifth roller 83 may be provided at the tip of the sliding rod 40. The sliding rod guide 35 is provided behind the master door 30 and includes a curved contact surface 35 a that contacts the fifth roller 83. The first pressing mechanism 82 presses the fifth roller 83 of the sliding rod 40 against the sliding rod guide 35a. Accordingly, when the master door 30 is opened and closed, the fifth roller 83 moves on the sliding rod guide 35a in the axial direction of the sliding rod 40, so that the sliding rod 40 can move in the axial direction of the sliding rod 40. Therefore, the rod drive mechanism can perform the interlock setting and the interlock off setting by opening and closing the master door 30.

  In the second embodiment, when the breaker 90 is set to ON by the external operation handle 92, the interlock setting is performed by the rod driving mechanism. Accordingly, when the breaker 90 is set to ON, the first sub door 20 cannot normally be opened, and the safety of the equipment panel 1a is further improved.

  The external operation handle 92 is located inside the outer shape of the master door 30 in a front view. As described above, even when the external operation handle 92 is disposed at a location away from the first sub door 20, it is possible to perform the interlock setting or the interlock off setting by the rod driving mechanism for the first sub door 20.

  In the second embodiment, the rod drive mechanism includes a first wire 86, a second wire 87, a wire casing 89, a link mechanism 85, and a second pressing mechanism 82a. The first wire 86 is connected to the tip 44 of the sliding rod 40a. The second wire 87 is connected to the external operation handle 92. The wire casing 89 is fixed inside the equipment panel 1a. The second wire 87 slides inside the wire casing 89. The link mechanism 85 is connected to the first wire 86 and the second wire 87 together. The second pressing mechanism 82a presses the sliding rod 40a in the direction away from the link mechanism 85 in the axial direction described above. As a result, the position of the tip 44 of the sliding rod 40a moves in accordance with the rotation of the external operation handle 92. Therefore, the external operation handle 92 can perform the interlock setting or the interlock off setting by the rod drive mechanism.

The door structure includes a second sub door 26 adjacent to the first sub door 20. If the first sub door 20 is not opened, the first sub door 20 is prevented from opening the second sub door 26. Accordingly, when the first sub door 20 is opened, the second sub door 26 is also opened, so that a wide opening is formed in the housing 10. Therefore, the maintenance work of the equipment inside the housing 10 by the worker is facilitated.

The sliding rods 40, 40a are arranged in the horizontal direction. In the side view, the suspension member 100 may be triangular. The bottom surface 102 of the suspension member 100 forms a horizontal plane. The upper surface 49a of the handle catch 49 is a horizontal plane. As a result, when the bottom surface 102 of the suspension member 100 not receiving an external force other than gravity contacts the top surface 49a of the handle catch 49, the first handle 21 is prevented from rotating.

  The external force applying member 60 may include a handle release bar 62, a release lever 63, and a release lever support member 64. The handle release bar 62 may be raised and lowered according to the setting of the handle release screw 22. The release lever 63 is rotatably connected to the upper end portion of the handle release bar 62. The release lever 63 is L-shaped. The release lever support member 64 is fixed to the first sub door 20. The release lever support member 64 rotatably supports the release lever 63. The suspension member 100 includes a protrusion 103 that protrudes from the side surface of the suspension member 100 in at least one of the left and right directions. When the handle release bar 62 rises, the release lever 63 hooks the protrusion 103 and rotates the suspension member 100 forward. Accordingly, when the external force applying member is set to release the interlock setting by the handle release screw 22, the suspension member 100 is rotated to a position where the bottom surface 102 of the suspension member 100 and the handle catch 49 do not overlap with each other when viewed from above. Can be made.

The rear end 103 a of the protrusion 103 may be positioned in front of the first end portion 49 b of the handle catch 49. Accordingly, the handle catch 49 is not caught by the protrusion 103 when the handle catch 49 is raised while sliding with the first sliding surface 101. Therefore, the first handle 21 can be rotated in the direction in which the first sub door 20 is unlocked.

[Modification]
As mentioned above, although two embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, A various change is possible in the range which does not deviate from the summary of invention.

  The hanging member 100 may not have a substantially triangular prism shape as shown in FIG. For example, as shown as the suspension member 100a in FIG. 14A, the side surface of the suspension member 100a may have a bell shape. Moreover, as shown as the suspension member 100b of FIG.14 (b), the side surface of the suspension member 100b may be a trumpet shape. Furthermore, the suspension member 100 may be a quadrangular pyramid or a cone.

  Further, the bottom surface 102 of the suspension member 100 and the top surface 49a of the handle catch 49 may not be flat. That is, even if a downward pressure is applied to the suspension member 100 when the bottom surface 102 and the upper surface 49a abut, the bottom surface 102 and the upper surface 49a have any shape as long as the bottom surface 102 and the upper surface 49a do not slide with each other. Also good.

  In the drawing, the master door 30, the first sub door 20, and the second sub door 26 are arranged in order from the left. However, the master door 30, the first sub door 20, and the second sub door 26 may be arranged in order from the right. In this case, the arrangement positions and orientations of the sliding rods 40 and 40a and the rod driving mechanism are opposite to each other. Further, in this case, the second end portion 49 c is also the left end portion of the handle catch 49.

  Further, the positional relationship between the sliding rod 40 or 40a and the front and rear of the suspension member 100 may be reversed. In this case, the handle catch 49 is provided on the rear side of the sliding rod 40 or 40a. Further, the external force application member 60 may have a mechanism for rotating the suspension member 100 backward. Further, the first end portion 49 b is a rear end portion of the handle catch 49.
