In the engaging tool 34, an engaging portion 34a that is detachably fitted to the engaged portion 35 of the fixing plate 32 is formed in a recessed shape at the tip of the fixing plate 32, and the opposite side. A shaft portion 34b that protrudes from the holding cylinder 33 through the operation lever 12 is provided, and an operation knob 37 is concentrically fixed to the projecting end side of the shaft portion 34b by screwing or the like. . The coil spring 36 is fitted on the shaft portion 34 b between the step portion 34 c of the engagement tool 34 and the operation lever 12.

  In this movable louver type fence, there is an opening / closing device 11 for each louver group 3, and the movable louver 9 of each louver group 3 usually has an engagement tool 34 of the operating lever 12 and an engaged portion at an appropriate position of the fixed plate 32. By being engaged with 35, it is fixed so as not to rotate at a predetermined opening / closing position. The movable louver 9 can be opened / closed individually for each louver group 3 according to the inside / outside of the fence and the like by rotating the operation lever 12 of each opening / closing device 11. Further, since the left and right opening / closing devices 11 are on the middle vertical shaft 2 side and the opening / closing device 11 is located away from the corner even in the case of an exit corner, an entrance corner, etc., each movable louver 9 can be easily opened and closed.

  For example, when the movable louver 9 is released from the closed state, first, the operation knob 37 is grasped and the engagement tool 34 is pulled in the disengagement direction (the direction indicated by the arrow a in FIG. 11) against the coil spring 36. Then, the engaging tool 34 slides in the disengaging direction inside the holding cylinder 33 against the coil spring 36, and the engaging portion 34 a at the tip is detached from the engaged portion 35 of the fixing plate 32.

  Next, while the operation knob 37 is held, the operation lever 12 is rotated around the support shaft 10 in the opening direction and in the direction indicated by the arrow b in FIG. Then, one movable louver 9 to which the operation lever 12 is fixed rotates around the support shaft 10 in the direction indicated by the arrow b. As the single movable louver 9 rotates, the left and right interlocking rods 13 connected to both ends of the movable louver 9 via the interlocking levers 25 operate in the downward direction around the support shaft 10. For this reason, the other movable louvers 9 connected to the left and right interlocking rods 13 via the interlocking lever 25 are opened in the opening direction around the respective support shafts 10 by substantially the same angle as the movable louver 9 directly operated by the operating lever 12. And rotate respectively.

  When each movable louver 9 is at a predetermined angle, when the pulling force on the operation knob 37 is released at that position, the engaging tool 34 is moved back toward the fixed plate 32 in the holding cylinder 33 by the bias of the coil spring 36. The slider slides in the direction of arrow a, and the engaging portion 34a engages with the engaged portion 35 at an appropriate position of the fixing plate 32 to fix the operation lever 12. Thus, each movable louver 9 can be fixed at its open position.

  In this embodiment, since the louver group 3 is composed of a plurality of movable louvers 9 and is arranged on both sides of the middle vertical rod 2 in the support frame 1, the construction is easier than the case where each louver group 3 is independent. At the same time, the design of the entire fence is improved. Since the support shaft 10 of each movable louver 9 is in a position where its rear end does not protrude rearward from the horizontal bar 5 of the support frame 1 when opening and closing, the support frame 1 is attached to the column 4 in the middle of the horizontal bar 5 in the left-right direction.

Since the engaging tool 34 that is detachably engaged is provided, the length to the protruding end of the operating lever 12 is longer than when the engaging portion 34a is engaged and disengaged by the operation of the operating lever 12 in the longitudinal direction. Therefore, the entire switchgear 11 can be reduced in size. Therefore, it is not necessary to secure a large space for installation, and there is no problem that the operation lever 12 protrudes rearward from the movable louver 9 and becomes an obstacle.

  Each fixing plate 32 that detachably fixes the operation lever 12 of each opening / closing device 11 at the opening / closing position is provided on both sides of the mounting base 41 fixed to the rear surface of the middle vertical rod 2 at substantially the same position in the vertical direction and the horizontal direction. Since the one mounting base 41 common to each switchgear 11 is erected from both sides to the rear, both switchgears 11 are efficiently arranged with a simple structure at the rear part of the narrow middle downboard 2. Can be placed.

  Moreover, the engaging tool 34 moves in a direction substantially parallel to the support shaft 10 so as to be engaged with and disengaged from the engaged portion 35 of the fixed plate 32. Since the operation lever 12 is fixed to the movable louver 9, the structure is simple as compared to the case where the operation lever 12 is pivotally supported on the middle vertical shaft 2 side. The lateral width of the side can be reduced, and at the same time, the interval between the fixing plate 32 and the operation lever 12 can be easily secured, and the engaging tool 34 and the coil spring 36 can be easily incorporated into the holding cylinder 33.

  Further, an engaging tool 34 that is detachably engaged with the engaged portion 35 and a coil spring 36 that urges the engaging tool 34 in the engaging direction are provided on the holding cylinder 33 on the free end side of the operating lever 12. Since the operation knob 37 is provided on the side opposite to the fixing plate 32 of the engagement tool 34, the structure is simple and the engagement knob 34 can be engaged and disengaged by the operation knob 37. Easy to do. Further, since the movable louver 9 to which the operation lever 12 is fixed and the other movable louvers 9 are interlocked by the interlocking rods 13 on the left and right sides, the interlocking rods on both sides are connected from the operation lever 12 via one movable louver 9. 13, the other movable louvers 9 can be operated from both sides, and each movable louver 9 can be opened and closed smoothly.

  Each interlocking rod 13 is in a cover portion 30 integral with the vertical rod 6, and caps 31 are provided to cover the upper and lower ends of the cover portion 30, and the upper and lower ends of the interlocking rod 13 are covered with the open side of the cover portion 30. Since each cap 31 is provided with the cap 31, the appearance can be improved despite the interlocking rod 13 on the rear side of the vertical rod 6, and injuries caused by the interlocking rod 13, the cover portion 30, and the like can be prevented. Moreover, the cap 31 has a U-shaped cover portion 31b, and not only covers the end portion of the interlocking rod 13 on one side, but also covers the end portion side of the cover portion 30 from three sides, so that the left and right sides are different. In addition to being able to be used for the two types of cover portions 30, the appearance can be further improved.

  When assembling the louvers 8 and 9 by attaching the holders 16 to both ends of the blade body 15, the press-fit protrusions 23 of the holder 16 are press-fitted into the hollow holes 19 c of the hollow portions 19 of the louvers 8 and 9 through the protrusions 23 c. To do. At this time, since both the front wall 19a, 23a and the rear wall 19b, 23b of the hollow portion 19 and the press-fitting protrusion 23 are V-shaped, they are pressed into the V-shaped slope and press-fitted in the hollow hole 19c. The protrusion 23 tends to move relatively toward the screw threaded portion 20. However, since the outer fitting portion 22 of the holder 16 covers the outer periphery of the blade body 15 and the tip of the lower blade portion 18 comes into contact with the inner peripheral portion of the tip of the outer fitting portion 22, the relative relationship between the blade body 15 and the holder 16 is reached.
