The shapes and functions of the middle shaft members 38a and 38b are the same as those of the lower shaft members 30a and 30b.

  The middle split cover 25 is fixed to the case 27 by first and second middle cover fixing screws 39a and 39b when in the fully closed position. The middle split cover 25 is provided with first and second dharma holes 25a and 25b through which the middle cover fixing screws 39a and 39b are passed. The middle split cover 25 is slidable in the length direction of the shaft with respect to the shafts of the hinges 29a and 29b.

  The upper divided cover 26 is connected to the case 27 via a plurality (two in this example) of hinges 40a and 40b. That is, the upper division cover 26 is a normal door-type cover.

  Next, the opening operation of the lower division cover 24 and the middle division cover 25 will be described. First, from the state of FIGS. 2 and 3, the lower cover fixing screws 37a and 37b are loosened as shown in FIGS. Thus, a gap (play) is generated between the heads of the cover fixing screws 37a and 37b and the front surface of the lower split cover 24, and the lower split cover 24 can be moved forward by that amount.

  Subsequently, as shown in FIGS. 9 and 10, the lower split cover 24 is moved forward (frontward when viewed from the worker on the car 6). At this time, the first and second lower shaft members 30a and 30b are relatively moved to the middle of the upper horizontal portion 33 of the first and second slits 22a and 22b.

  Thereafter, using the play of the shafts of the hinges 28a and 28b, the lower divided cover 24 is moved slightly upward as shown in FIGS. Accordingly, the first and second cover fixing screws 37a and 37b are relatively moved from the small diameter portion to the large diameter portion of the first and second dharma holes 24a and 24b, respectively.

  From this state, as shown in FIGS. 14 and 15, the lower divided cover 24 is moved forward again, and the first and second dharma holes 24 a and 24 b are formed in the first and second cover fixing screws 37 a and 37 b. Let it pass. At this time, the first and second lower shaft members 30a and 30b are relatively moved to the end opposite to the lower divided cover 24 of the upper horizontal portion 33 of the first and second slits 22a and 22b. The

  Next, using the play between the head 32 of the first and second lower shaft members 30a, 30b and the lower slide plate 22, the lower split cover 24 is slid to the side (left side in FIG. 2). . In this state, as shown in FIGS. 16 to 18, the lower divided cover 24 and the lower slide plate 22 are slid upward along the first and second slits 22a and 22b.

  At this time, since the lower split cover 24 is moved forward from the fully closed position, it can be slid upward without interfering with the intermediate split cover 25. Further, since the lower slide plate 22 is moved to the left in FIG. 2 together with the lower split cover 24, it can be slid upward without interfering with the middle slide plate 23.

  Further, as shown in FIG. 19, the first and second lower shaft members 30a and 30b are moved relatively downward along the vertical portions 34 of the first and second slits 22a and 22b. At this time, since the diameter of the head portion 32 is larger than the width dimension of the slits 22a and 22b, the lower slide plate 22 does not come off from the lower shaft members 30a and 30b.

  When the lower split cover 24 is moved upward until the lower shaft members 30 a and 30 b abut against the lower end of the vertical portion 34, the lower split cover 24 and the lower slide plate 22 are moved forward along the lower horizontal portion 35. Then, the lower-stage divided cover 24 and the lower-stage slide plate 22 are moved downward until the lower-stage shaft members 30a and 30b come into contact with the upper end of the folded-back portion 36. Accordingly, as shown in FIGS. 20 and 21, the lower split cover 24 is held at the position moved upward.

  Thereafter, by expanding the lower split cover 24 around the axes of the hinges 28a and 28b, as shown in FIGS. 22 and 23, the entire portion corresponding to the lower split cover 24 of the opening of the case 27 is opened. The

  24 and 25 show a state in the middle of moving the middle-stage divided cover 25, FIGS. 26 and 27 show a state where the middle-stage divided cover 25 is held in the open position, and FIGS. 28 and 29 show the middle stage. The state which expanded the division | segmentation cover 25 to the fully open position is shown.

  The opening operation of the middle division cover 25 is the same as the opening operation of the lower division cover 24. In other words, the middle-stage divided cover 25 can be moved to the open position without being interfered with the upper-stage divided cover 26 by the same operation as the lower-stage divided cover 24, and can be expanded to the fully-open position.

  Note that the middle-stage divided cover 25 can be opened first, and only the middle-stage divided cover 25 or the lower-stage divided cover 24 can be opened independently.

  In such an elevator control panel, the opening of the case 27 can be easily made while the split covers 24 and 25 are connected to the control panel main body 21 while avoiding interference between the split covers 24 and 25 and the car 6 and the safety fence 11. The control device in the case 27 can be accessed.

  Further, since the slide plate 22 (23) is provided with the first and second slits 22a, 22b (23a, 23b) at a distance from each other, the first slit 22a (23a) has a first slit. Since the shaft member 30a (38a) is passed and the second shaft member 30b (38b) is passed through the second slit 22b (23b), when the split cover 24 (25) is pulled up, the split cover 24 (25 ) It can be held alone.

  Furthermore, since the shape of the lower end part of 1st and 2nd slit 22a, 22b (23a, 23b) is the shape folded in J shape, the division | segmentation cover 24 (25) can be hold | maintained in an open position. .

  Furthermore, since the first and second shaft members 30a, 30b (38a, 38b) are arranged to be shifted from each other in the depth direction and the vertical direction of the case 27, the divided cover 24 (25) is held in the open position. In this case, the split cover 24 (25) can be prevented from falling (falling in the direction in which the upper end portion of the slide plate 22 (23) is separated from the side surface portion of the case 27).

  Further, play is provided between the head 32 of the first and second shaft members 30a, 30b (38a, 38b) and the slide plate 22 (23), and the slide plate 22 (23) is provided by the amount of play. Since the split cover 24 (25) is slidable in the width direction of the case 27, when the split cover 24 (25) is moved upward, the slide plate 22 (23) Interference with a cover or the like can be prevented.

  Further, the divided cover 24 (25) is provided with dharma holes 24a and 24b (25a and 25b) through which cover fixing screws 37a and 37b (39a and 39b) are passed, and the divided cover 24 (25) has a hinge 28a. , 28b (29a, 29b) is slidable in the axial direction of the shaft, so that the cover fixing screws 37a, 37b can be removed without completely removing the cover fixing screws 37a, 37b (39a, 39b). The split cover 24 (25) can be moved upward simply by loosening (39a, 39b).

  A handle for pulling up the divided cover 24 (25) may be provided on the slide plate 22 (23). Accordingly, the lifting operation of the divided cover 24 (25) can be performed without providing the protrusions and the handrail holes in the divided cover 24 (25).
