[0007] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. Note that the disclosure is merely an example, and any suitable modification that a person skilled in the art can easily conceive while maintaining the gist of the invention is naturally included in the scope of the present invention. In addition, in order to make the drawings and explanations clearer, the width, thickness, shape, etc. of each part may be shown in a schematic manner compared to the actual embodiment, but this is merely an example and does not limit the interpretation of the present invention. In addition, in this specification and each figure, elements similar to those described above with respect to the previous figures may be given the same reference numerals, and detailed explanations may be omitted as appropriate. Hereinafter, a control panel for an elevator system according to one embodiment will be described in detail with reference to the drawings.

[0008] Fig. 1 is a schematic diagram showing the configuration of an elevator system 10 according to a first embodiment. Note that Fig. 1 shows a state in which an operator (maintenance worker) is inspecting a control panel 14. 1, the elevator device 10 includes a wall portion 12, a car 13, a control panel 14, and a door 15. The wall portion 12 extends along an ascending / descending direction Y and defines a hoistway 11. The car 13 is formed in a box shape having an upper part 13a, and carries passengers and moves up and down in the elevator shaft 11. The upper part 13a of the car 13 is used as a foothold for maintenance personnel when the control panel 14 breaks down or is being inspected.

[0009] The control panel 14 is disposed in the elevator shaft 11, and is supported by a support member 16 fixed to the wall portion 12. The control panel 14 does not face the car 13 in the ascending / descending direction Y. In other words, the control panel 14 is spaced apart from the car 13 in a direction perpendicular to the ascending / descending direction Y. The control panel 14 also faces the door 15, and includes a control panel main body 17 and a cover 18. The control panel main body 17 houses electronic devices and electronic / electrical circuits for controlling the operation of various devices of the elevator device 10, such as the movement of the car 13. Door 15 is a door through which passengers can travel between car 13 and floor (hall) 19, and opens when a passenger gets off car 13 to floor 19 or when a passenger gets on car 13 from floor 19.

[0010] In addition to the wall portion 12, the car 13, the control panel 14, and the door 15, the elevator device 10 is equipped with various devices for raising and lowering the car 13, such as a hoisting machine (not shown) and a counterweight wound around the rope of the hoisting machine. When performing maintenance or inspection, a worker moves the car 13 so that the position of the upper part 13a is approximately the same as the floor 19, opens the door 15, and then gets on the upper part 13a. After that, the worker opens the cover 18 of the control panel 14 and performs maintenance or inspection of the electronic devices housed in the control panel main body 17.

[0011] Next, the configuration of the control panel 14 will be described with reference to FIGS. Fig. 2 is a front view of the control panel 14 according to the first embodiment. Fig. 3 is an enlarged perspective view of a portion A in Fig. 2. Fig. 4 is an enlarged perspective view of a portion B in Fig. 2. Fig. 5 is a cross-sectional view taken along line CC in Fig. 3. Fig. 6 is an enlarged perspective view of a portion D in Fig. 3. 2 to 6, the control panel 14 includes a box-shaped control panel body 17 having an opening 28 on the front side, a cover 18 composed of a plurality of covers 18a, 18b, 18c, and 18d, and a plurality of stoppers ST1, ST2, ST3, ST4, ST5, and ST6. In the example shown in Fig. 2 to 6, the cover 18 covers the opening 28, and all of the covers 18a, 18b, 18c, and 18d are positioned in the closed position to close the opening 28.

[0012] The control panel body 17 has a pair of side walls 20 and a plurality of engaged portions 22. The pair of side walls 20 are formed in a rectangular shape extending in the lifting / lowering direction Y and face each other with a gap between them. The side walls 20 have a guide portion 21 formed at one end on the front side and extending in the left-right direction X (see FIG. 5). The multiple engaged parts 22 are provided on the pair of side walls 20 and positioned side by side in the lifting / lowering direction Y. The multiple engaged parts 22 are also provided stacked in the left-right direction X (see FIG. 5). Each engaged part 22 is formed in a substantially L-shape and has a fixing part 24 fixed to the side wall 20 or the engaged part 22, and a guide part 26 formed to extend from the fixing part 24 in the left-right direction X.

[0013] 5, the fixed portion 24 of one engaged portion 22 is fixed to the side wall 20, and the fixed portion 24 of the other engaged portion 22 is fixed to the fixed portion 24 of the one engaged portion 22. In addition, the guide portion 26 of one engaged portion 22 faces the guide portion 21 of the side wall 20 with a gap therebetween, and the guide portion 26 of the other engaged portion 22 faces the guide portion 26 of the one engaged portion 22 with a gap therebetween. Since the engaged portion 22 is configured as described above, the control panel body 17 has groove portions 29 between the guide portion 21 and the guide portion 26, and between one guide portion 26 and the other guide portion 26. The guide portion 26 has a plurality of recesses DE recessed in the left-right direction X. In one example, the recesses DE are positioned side by side in the lifting / lowering direction Y.

[0014] Each of the covers 18a, 18b, 18c, and 18d has a plate-shaped member 30a, 30b, 30c, and 30d, an engagement portion 32a, 32b, 32c, and 32d, and a handle 34. The plate-shaped members 30a, 30b, 30c, and 30d are housed in the groove portion 29 and are formed in a rectangular shape extending in the lifting / lowering direction Y. The plate-shaped members 30a, 30b, 30c, and 30d have a width that is approximately the same as the distance between a pair of side walls 20.

[0015] In the example shown in Figure 5, the plate-shaped member 30a is accommodated in a groove portion 29 defined by the guide portion 26 of the engaged portion 22, and the plate-shaped member 30b is accommodated in a groove portion 29 defined by the guide portion 21 of the side wall 20 and the guide portion 26 of the engaged portion 22. Similarly, plate-shaped member 30c is accommodated in groove portion 29 defined by guide portion 21 of side wall 20 and guide portion 26 of engaged portion 22, and plate-shaped member 30d is accommodated in groove portion 29 defined by guide portion 26 of engaged portion 22. Because the plate-shaped members 30a, 30b, 30c, and 30d are configured as described above, the plate-shaped members 30a, 30b, 30c, and 30d are capable of moving (sliding) inside the groove portion 29, and the covers 18a, 18b, 18c, and 18d are capable of moving in the lifting and lowering direction Y (hereinafter also referred to as the "sliding direction").

[0016] The multiple engagement portions 32a, 32b, 32c, and 32d each have the same configuration, so the configuration of the engagement portions 32a, 32b, 32c, and 32d will be described using the engagement portion 32a as an example. 6, the engagement portion 32a has a pair of engagement projections 38, a plurality of guide pins 40, a pair of fasteners 42, and a pair of biasing members 44. The pair of engagement projections 38 are positioned with a gap therebetween in the left-right direction X. Each engagement projection 38 is formed in a substantially L-shape and has a slide portion 46 in contact with the plate-like member 30a, an attachment portion 48 formed by extending perpendicularly from the slide portion 46, and an elongated hole H extending in the left-right direction X. The elongated hole H is formed penetrating the slide portion 46 and positioned next to each other in the left-right direction X.

[0017] The guide pin 40 is inserted through the long hole H and fixed to the plate-shaped member 30a. In one example, two guide pins 40 are provided for one engagement protrusion 38. The fastener 42 is located between the two guide pins 40, inserted through the long hole H, and fixed to the plate-shaped member 30a. The biasing member 44 is provided on each of the pair of engagement protrusions 38, and has one end fixed to the attachment portion 48 and the other end fixed to the fastener 42. The biasing member 44 is a coil spring, and is in a natural length or in a state extended from its natural length when the slide portion 46 is housed in the recess DE. In other words, the biasing member 44 shown in Fig. 6 biases one (right) engagement protrusion 38 toward one (right) recess DE, and biases the other (left) engagement protrusion 38 toward the other (left) recess DE.

[0018] Since the engaging portion 32a is configured as described above, the pair of engaging projections 38 can move in the left-right direction X along the long hole H relative to the plate-shaped member 30a. In the example shown in FIG. 6, the engaging portion 32a is in a state of engaging with the engaged portion 22, and the end of the engaging projection 38 (slide portion 46) is housed in the recess DE. At this time, in the sliding direction Y, the side surface of the slide portion 46 faces the inner surface of the recess DE, and the movement of the plate-shaped member 30a is restricted. In other words, when the engaging portion 32a is engaged with the engaged portion 22, the movement of the cover 18 in the sliding direction Y is restricted.

[0019] The handles 34 are located below the engagement portions 32a, 32b, 32c, and 32d, respectively. The handles 34 have a gripping portion 341 extending in the left-right direction X, and fixing portions 342 extending from both ends of the gripping portion 341 to the plate-like members 30a, 30b, 30c, and 30d. The fixing portions 342 are fixed to the plate-like members 30a, 30b, 30c, and 30d.

[0020] The stoppers ST1, ST2, ST3 are provided on the pair of side walls 20. The stopper ST1 is formed in a plate shape and is fixed to the side wall 20 (more specifically, the guide portion 21). The stopper ST1 is located below the cover 18a (plate-shaped member 30a) in the sliding direction Y, and has an opposing portion O1 opposing the plate-shaped member 30a. The stopper ST2 is located below the cover 18b in the sliding direction Y and is formed in a substantially L-shape. The stopper ST2 has a fixed portion F2 fixed to the side wall 20 and an opposing portion O2 opposing the plate-like member 30b in the sliding direction Y. The stopper ST3 is located below the stopper ST6 and is formed in a substantially L-shape. The stopper ST3 has a fixed portion F3 fixed to the side wall 20 and an opposing portion O3 opposing the stopper ST6 in the sliding direction Y.

[0021] A plurality of stoppers ST4, ST5, ST6 are provided on the plate-shaped members 30a, 30c, 30d. The stopper ST4 is located lower than the plate-shaped member 30b in the sliding direction Y. The stopper ST4 has a fixed portion F4 fixed to the plate-shaped member 30a, a facing portion O4 facing the plate-shaped member 30b, and an extension portion P formed by extending upward from the facing portion O4. The stopper ST5 is located above the plate-shaped member 30d in the sliding direction Y and is formed in a substantially L-shape. The stopper ST5 has a fixed portion F5 fixed to the plate-shaped member 30c and an opposing portion O5 opposing the plate-shaped member 30d in the sliding direction Y. The stopper ST6 is located above the stopper ST3 and is formed in a generally L-shape. The stopper ST6 has a fixed portion F6 fixed to the plate-like member 30d and an opposing portion O6 opposing the stopper ST3. The control panel 14 according to the first embodiment is configured as described above.

[0022] Next, the operation of the cover 18 will be described. First, the case of opening the covers 18a, 18b will be described with reference to Figs. 3, 7, 8, and 9. Fig. 7 is a plan view showing a state in which the engagement between the engaging portion 32b and the engaged portion 22 is released. Fig. 8 is a perspective view showing an example of a state in which the cover 18b has been moved upward from the state shown in Fig. 3. Fig. 9 is a perspective view showing an example of a state in which the cover 18a has been moved upward from the state shown in Fig. 8.

[0023] As shown in Fig. 3, the covers 18a and 18b are in the closed position. The plate-shaped member 30a is in contact with the opposing portion O1 of the stopper ST1, and the plate-shaped member 30b is in contact with the opposing portion O2 of the stopper ST2. In other words, the downward movement of the covers 18a and 18b is restricted by the stoppers ST1 and ST2. In order to move the covers 18a and 18b upward from the state shown in Fig. 3, it is necessary to release the engagement of the engaging portions 32a and 32b with the engaged portion 22. Hereinafter, a method of releasing the engagement of the engaging portions 32a, 32b, 32c, and 32d with the engaged portion 22 will be described using the engaging portion 32b as an example.

[0024] 7, when disengaging the engaging portion 32b from the engaged portion 22, the pair of engaging protrusions 38 is moved in the left-right direction X to pull out the slide portion 46 from the recess DE. More specifically, the worker pinches the mounting portion 48 with his / her fingers and moves the engaging protrusions 38 so as to reduce the gap between the pair of engaging protrusions 38. When the engaging portion 32b is disengaged from the engaged portion 22, the slide portion 46 and the recess DE do not face each other in the sliding direction Y. Therefore, the worker can move the cover 18b upward while keeping the engaging portion 32b disengaged (while pinching the mounting portion 48).

[0025] As shown in FIG. 8, the cover 18b is moved upward to a desired position, and then held at the desired position by the engagement of the engaging portion 32b with the engaged portion 22. That is, the worker moves the cover 18b upward to a position where the opening 28 required for maintenance or inspection can be opened, and the engaging protrusion 38 is accommodated in the recess DE, which is at a higher position than the engaging protrusion 38 at this time. The worker can also safely engage the engaging portion 32b with the engaged portion 22 by holding the gripping portion 341 of the handle 34 with the hand opposite to the hand holding the mounting portion 48 and releasing the hand from the mounting portion 48 while maintaining the height of the cover 18b. By engaging the engaging portion 32d with the engaged portion 22, the cover 18b can be maintained at a desired position (height), and the worker can perform maintenance or inspection of the electronic device.

[0026] 9, after cover 18a has been moved upward to a desired position, it is held at the desired position by engagement of engaging portion 32a with engaged portion 22. When cover 18a is moved upward, plate member 30a does not come into contact with plate member 30b because groove portion 29 in which plate member 30a is accommodated is different from groove portion 29 in which plate member 30b is accommodated (see FIG. 5). After engaging the engaging portion 32a with the engaged portion 22, the worker can perform maintenance or inspection of the electronic device.

[0027] Here, a case where the engagement of the engaging portions 32a, 32b with the engaged portion 22 is unintentionally released from the state shown in FIG. 9 due to deterioration or damage of the biasing member 44 will be described. When the engagement of the engaging portion 32b with the engaged portion 22 is released, the cover 18b falls downward, but the plate-like member 30b collides with the stoppers ST2 and ST4 and is supported by the stoppers ST2 and ST4. When the position of the cover 18a is higher than the position shown in Fig. 9, the cover 18b is supported only by the stopper ST4. On the other hand, when the cover 18a is lower than the position shown in Fig. 9, the cover 18b is supported only by the stopper ST2. When the engagement of the engaging portion 32a with the engaged portion 22 is released, the cover 18a falls downward, but the plate-like member 30a collides with the stopper ST1 and is supported by the stopper ST1.

[0028] Next, a case where the covers 18c and 18d are opened will be described with reference to Figures 4 and 10. Figure 10 is a perspective view showing an example of a state where the covers 18c and 18d have been moved downward from the state shown in Figure 4. As shown in Fig. 4, the covers 18c and 18d are in the closed position. At this time, the stopper ST5 is separated from the plate-shaped member 30d, and the stopper ST6 is separated from the stopper ST3. The engaging projection 38 of the engaging portion 32c is accommodated in the uppermost recess DE of the corresponding engaged portion 22. From the state shown in FIG. 4, cover 18d is moved downward so that engaging portion 32d engages with engaged portion 22, and then cover 18c is moved downward so that engaging portion 32c engages with engaged portion 22, thereby resulting in the state shown in FIG.

[0029] 10, after the covers 18c, 18d are moved to any position, they are held at the any position by the engagement of the engaging portions 32c, 32d with the engaged portions 22. In one example, the engaging projections 38 are accommodated in the recesses DE located at the lowest position of the corresponding engaged portions 22, and the covers 18c, 18d are in the open position where the openings 28 are fully opened. At this time, the facing portion O5 of the stopper ST5 contacts the plate-like member 30d, and the facing portion O6 of the stopper ST6 contacts the facing portion O3 of the stopper ST3.

[0030] Here, a case where the engagement of the engaging portions 32c, 32d with the engaged portion 22 is unintentionally released from the state shown in FIG. 4 due to deterioration or damage of the biasing member 44 will be described. When the engagement of the engaging portion 32c with the engaged portion 22 is released, the cover 18c falls downward, but the opposing portion O5 of the stopper ST5 collides with the plate-like member 30d and is supported by the plate-like member 30d. When the engagement of the engaging portion 32d with the engaged portion 22 is released, the cover 18d falls downward, but the opposing portion O6 of the stopper ST6 collides with the opposing portion O3 of the stopper ST3 and is supported by the stopper ST3.

[0031] In summary, the covers 18a, 18b, 18c, and 18d can be maintained at any position (height) by engaging the engaging portions 32a, 32b, 32c, and 32d with the engaged portions 22. Furthermore, the lower limit position of cover 18a is defined by stopper ST1, the lower limit position of cover 18b is defined by stoppers ST2 and ST4, the lower limit position of cover 18c is defined by stopper ST5, and the lower limit position of cover 18d is defined by stoppers ST3 and ST6.

[0032] That is, the movements of the covers 18a, 18b, 18c, and 18d are limited by the stoppers ST1, ST2, ST3, ST4, ST5, and ST6 so that the covers do not go beyond the range from the open position to the closed position. From the above, the control panel 14 has a non-detachable cover structure that can maintain the opening 28 open without removing the cover 18 from the control panel main body 17, and can maintain the plate-shaped members 30a, 30b, 30c, and 30d contained within the groove portion 29 by the stoppers ST1, ST2, ST3, ST4, ST5, and ST6.

[0033] The effects of the first embodiment will be described. According to the control panel 14 of the elevator device 10 according to the first embodiment, the control panel 14 can move (slide) the covers 18a, 18b, 18c, and 18d from a closed position to an open position to open and close the opening 28. Since the range in which the cover 18 moves is different from the range in which the car 13 moves, it is possible to prevent the cover 18 from coming into contact with equipment such as the car 13. For example, even if the cover 18 is forgotten to be closed, the cover 18 will not come into contact with the car 13.

[0034] The control panel 14 is provided with stoppers ST1, ST2, ST3, ST4, ST5, and ST6, which can prevent the cover 18 from moving beyond the range from the open position to the closed position. Further, the stoppers ST1, ST2, ST3, ST4, ST5, and ST6 define the lower limit positions of the range in which the covers 18a, 18b, 18c, and 18d can move, thereby preventing the cover 18 from falling off.

[0035] The covers 18a, 18b, 18c, and 18d have engaging portions 32a, 32b, 32c, and 32d. The control panel body 17 has an engaged portion 22. When the engaging portions 32a, 32b, 32c, and 32d are engaged with the engaged portion 22, the movement of the covers 18a, 18b, 18c, and 18d in the sliding direction Y is restricted. Therefore, the opening 28 can be maintained open without removing the cover 18 from the control panel body 17.

[0036] The engaging portions 32a, 32b, 32c, and 32d have engaging protrusions 38 that are movable in the left-right direction X, and the engaged portion 22 has a recess DE formed by being recessed in the left-right direction X. Therefore, the covers 18a, 18b, 18c, and 18d can be maintained in any position without using fastening members such as bolts. Furthermore, the engaging portions 32a, 32b, 32c, and 32d have a biasing member 44 that biases the engaging projections 38 toward the recesses DE, and each of the pair of engaging projections 38 is biased toward the recesses DE. Therefore, an operator can release the engagement of the engaging portions 32a, 32b, 32c, and 32d with the engaged portion 22 with one hand, improving workability.

[0037] In the first embodiment, the control panel 14 has both a structure that opens by moving covers 18a, 18b upward and a structure that opens by moving covers 18c, 18d downward, but it does not have to have both structures. For example, if the control panel 14 is installed near the ceiling of the elevator device 10, it may only have a structure for moving downward so as to avoid contact between the ceiling and the cover 18.

[0038] Next, the control panel 14 of the elevator apparatus 10 according to the second embodiment will be described. In the second and third embodiments described below, the same parts as those in the first embodiment described above are given the same reference numerals, and detailed descriptions thereof will be omitted or simplified, and the description will focus on parts that differ from the first embodiment. Second embodiment Fig. 11 is an enlarged perspective view of the control panel 14 of the elevator apparatus 10 according to the second embodiment. Fig. 11 shows a portion A of the control panel 14 in Fig. 2.

[0039] 11, the engaging portion 32a further has a pair of first connecting members 50, and the engaging portion 32b further has a pair of second connecting members 52. The pair of first connecting members 50 are formed in a columnar shape extending along the sliding direction Y, and one end is fixed to the sliding portion 46 of the engaging portion 32a. The pair of second connecting members 52 are formed in a cylindrical shape along the sliding direction Y, and are fixed to the sliding portion 46 at the engaging portion 32b. The second connecting members 52 have through holes formed penetrating along the sliding direction Y, and the first connecting members 50 are inserted into the through holes.

[0040] That is, the engaging portion 32a is connected to the engaging portion 32b via the first connecting member 50 and the second connecting member 52. Therefore, when the engaging portion 32a is released from the engagement with the engaged portion 22, the engaging portion 32b is also released from the engagement with the engaged portion 22. More specifically, a force in the left-right direction X applied to the engaging protrusion 38 of the engaging portion 32a is transmitted from the outer circumferential surface of the first connecting member 50 to the inner circumferential surface of the second connecting member 52 and acts on the engaging protrusion 38 of the engaging portion 32b, causing the sliding portion 46 of the engaging portion 32b to move out of the groove portion DE.

[0041] In the example shown in FIG. 11, the cover 18b is supported by the stopper ST2 and does not move downward even when the engagement of the engaging portion 32b with the engaged portion 22 is released. When the cover 18a is moved upward with the engagement of the engaging portion 32a and the engaging portion 32b with the engaged portion 22 released, the cover 18b does not move until the stopper ST4 comes into contact with the plate-shaped member 30b. When the stopper ST4 comes into contact with the plate-shaped member 30b, the cover 18b moves upward integrally with the cover 18a in conjunction with the cover 18a. When the engaging portion 32a is engaged with the engaged portion 22 at any position, a force is transmitted in the same manner as when the engagement is released, and the engaging portion 32b engages with the engaged portion 22.

[0042] The effects of the second embodiment will be described. According to the control panel 14 of the elevator apparatus 10 according to the second embodiment, the engaging portion 32a has a first connecting member 50, and the engaging portion 32b has a second connecting member 52. The first connecting member 50 and the second connecting member 52 connect the engaging portion 32a and the engaging portion 32b. Therefore, by releasing the engagement of one of the engaging portions 32a, 32b with the engaged portion 22, the engagement of the other engaging portion 32a, 32b with the engaged portion 22 can be released, thereby obtaining a control panel 14 that can easily open and close the opening 28.

[0043] In the second embodiment, only the structure of the covers 18a, 18b that open upward among the multiple covers 18a, 18b, 18c, and 18d has been described, but the present invention can also be applied to the structures of the covers 18c, 18d that open downward. For example, the present invention can be applied by fixing the first connecting member 50 to the slide portion 46 of the engagement portion 32c and fixing the second connecting member 52 to the slide portion 46 of the engagement portion 32d.

[0044] Next, the control panel 14 of the elevator system 10 according to the third embodiment will be described. Third embodiment Fig. 12 is an enlarged perspective view of the control panel 14 of the elevator apparatus 10 according to the third embodiment. Fig. 12 shows part A of the control panel 14 in Fig. 2. Fig. 12 also shows an enlarged view of the state in which the first locking portion 60 is locked to the second locking portion 64.

[0045] 12, the engagement portions 32a, 32b have a pair of first limiting members 54 and a pair of second limiting members 56. The first limiting members 54 are formed in a substantially L-shape and have a connecting portion 58 connected to the mounting portion 48 of the engagement projection 38, and a first locking portion 60 formed to extend in a direction perpendicular to the left-right direction X. The first limiting member 54 is connected to the mounting portion 48 so as to be rotatable about the connecting portion 58.

[0046] The pair of second limiting members 56 are positioned with a gap therebetween in the left-right direction X. The second limiting members 56 are formed in a substantially L-shape and have a fixing portion 62 fixed to the plate-like members 30a, 30b, and a second locking portion 64 formed to extend in a direction perpendicular to the left-right direction X and the sliding direction Y. When the engaging portions 32a, 32b are engaged with the engaged portion 22, the pair of second engaging portions 64 are located inside the pair of first engaging portions 60 in the left-right direction X, and when the engaging portions 32a, 32b are disengaged from the engaged portion 22, the pair of second engaging portions 64 are located outside the pair of first engaging portions 60 in the left-right direction X.

[0047] In the third embodiment, the first limiting member 54 and the second limiting member 56 can maintain a state in which the engaging portions 32a, 32b are disengaged from the engaged portion 22. Below, a procedure for maintaining the disengaged state will be described using the engaging portion 32a as an example. First, the engagement of the engaging portion 32a with the engaged portion 22 is released, and the first restricting member 54 is rotated so that the first locking portion 60 is disposed between the pair of second locking portions 64. Thereafter, when the engaging protrusion 38 (mounting portion 48) is released, the first locking portion 60 is locked to the second locking portion 64 by the biasing force of the biasing member 44. At this time, since the movement of the engaging protrusion 38 in the left-right direction X is restricted, the state in which the engagement of the engaging portion 32a with the engaged portion 22 is released can be maintained.

[0048] When the cover 18a is moved upward in a state in which the engagement of the engaging portions 32a and 32b with the engaged portion 22 is released by the above-mentioned method, only the cover 18a moves until the stopper ST4 comes into contact with the plate-shaped member 30b, and when the stopper ST4 comes into contact with the plate-shaped member 30b, the cover 18b moves upward together with the cover 18a. After the cover 18a and the cover 18b are moved to an arbitrary position, the pair of first restricting members 54 are rotated while holding the handle 34 of the cover 18a so that the engagement of the first engaging portion 60 with the second engaging portion 64 is released, and the engaging projection 38 is accommodated in the recess DE by the biasing force of the biasing member 44, and the engaging portions 32a and 32b engage with the engaged portion 22.

[0049] The effects of the third embodiment will be described. According to the control panel 14 of the elevator apparatus 10 in the third embodiment, the engagement portions 32a, 32b have a first restricting member 54 having a first locking portion 60, and a second restricting member 56 having a second locking portion 64. This makes it possible to obtain a control panel 14 in which a plurality of covers 18a, 18b can move integrally with a simpler configuration than the second embodiment. In the third embodiment, only the structure of the covers 18a, 18b that open upward has been described, but the present invention is also applicable to the structure of the covers 18c, 18d that open downward, and the engagement portions 32c, 32d may have a first limiting member 54 and a second limiting member 56.

These new embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims. Multiple embodiments can be combined as necessary. [Explanation of symbols]
