Description

Elevator hall operating device

[0001] The present invention relates to an elevator hall operating device, and in particular to a device that sets up a lower operating panel below an indicator and an upper operating panel without drilling new wiring holes in the hall wall, thereby suppressing an increase in the number of parts, preventing damage to wiring, and facilitating installation work.

[0002] Elevators generally undergo renovation work known as modernization as needed to address aging or improve functionality. This renovation work may involve replacing the indicators of existing hall operating devices with new indicators, such as replacing analog indicators with digital indicators, as in the configuration described in Patent Document 1. A control panel with buttons for calling elevators is integrally installed below the indicators.

[0003] FIG. 11 shows the vicinity of a landing where an existing landing operating device 100 is installed. FIG. 12 is a cross-sectional view taken along the line A-A in FIG. 11 . As shown in FIGS. 11 and 12 , electrical components such as lamps 104 protrude significantly from the back side of an indicator device 101 including an existing analog indicator 102 and an operation panel 103, and electrical components such as wiring and a circuit board 105 are connected to the electrical components. A landing box 15 is embedded and fixed in the landing wall 10. The landing box 15 is a rectangular box with an opening at the landing-side end of the landing wall 10 (the left end in FIG. 12 ). The landing box 15 isolates and protects the housed electrical components from external foreign objects such as water and dust. Furthermore, even when the existing indicators are replaced with new digital indicators or operation panels using LCD displays or LEDs, the landing box protects electrical components such as wiring and connectors from external foreign objects.

[0004] When replacing the indicator during the above-mentioned renovation work, it is common to reuse the existing landing box 15 because it is difficult to remove the existing landing box 15 that is embedded and fixed in the landing wall 10.

[0005] Patent Document 2 describes a configuration in which a metal mounting plate is fixed to a storage box (landing box) fixed to the wall of a landing so as to cover the open end of the storage box, and a general indicator and a wheelchair indicator below the general indicator are attached to the front side of the mounting plate by magnets or the like. An upper operation panel is integrally provided with the general indicator. A lower operation panel is provided with the wheelchair indicator. In this configuration, an upper opening is formed on the upper side of the mounting plate through which the operation wiring of the upper operation panel passes. A lower opening is formed on the lower side of the mounting plate through which the operation wiring of the lower operation panel passes. The operation wiring of the lower operation panel is guided by a guide member fitted into the lower opening and drawn out into the storage box.

[0007] When replacing the indicator of a hall operating device, there is an increasing demand to add a control panel for wheelchair users below. In this case, a lower operating panel with dedicated push buttons for wheelchair users must be installed below the indicator and a general upper operating panel. However, there are usually no holes in the wall of the building's hall below the existing hall box for routing the wiring connected to the lower operating panel. Therefore, it is necessary to drill a new wiring hole in the hall wall that connects the elevator hall and the hoistway, but this drilling work is difficult and requires a lot of time. In addition, noise during construction can be a problem for residents and others.

[0008] The configuration described in Patent Document 2 above may allow the lower control panel to be installed below the upper indicator and upper control panel without drilling new wiring holes in the landing wall. However, a lower opening is provided in the mounting plate separately from the upper opening. Furthermore, a magnet and a concave-convex engaging portion for positioning the indicator relative to the mounting plate are provided between the upper and lower openings. This reduces the vertical length of the lower opening. Therefore, the portion of the operation wiring of the lower control panel near the portion leading out from the lower opening of the mounting plate must be bent sharply near the upper end of the lower opening. Therefore, there is a risk that the operation wiring may come into contact with the edge of the metal mounting plate and be damaged.

[0009] In the configuration described in Patent Document 2, it is conceivable to guide the operation wiring with a guide member fitted into the lower opening to prevent the operation wiring from being damaged. However, this may increase the number of parts and make the installation work more tedious. Furthermore, the degree of freedom in routing the wiring may be significantly limited. This may also make the installation work more tedious.

[0010] An object of the present invention is to provide an elevator hall operating device that allows a lower operating panel to be installed below an indicator and an upper operating panel without drilling new wiring holes in the hall wall, that prevents an increase in the number of parts, prevents damage to wiring, and facilitates installation work.

[0011] An elevator hall operating device according to the present invention includes: a hall wall having a through opening that opens to an elevator hall and a hoistway; a hall box that is provided within the through opening and protects the housed electrical components from external foreign objects; a mounting plate that is fixed to the hall wall and covers the hall-side opening of the through opening; and an upper indicator, a middle upper operating panel, and a lower lower operating panel that are fixed to the mounting plate from the hall side, wherein the mounting plate is provided with a pull-out opening that extends vertically from a position that corresponds to the hall box and is higher than the top end of the upper operating panel to a position that corresponds to the lower operating panel, and operation wiring for at least the lower operating panel is pulled out to the hall box through the pull-out opening.

[0012] According to the elevator hall operating device of the present invention, the mounting plate is provided with a vertically extending drawer opening from a position corresponding to the hall box and higher than the top of the upper operating panel to a position corresponding to the lower operating panel, and at least the operation wiring of the lower operating panel is drawn through the drawer opening to the hall box. This allows a lower operating panel for wheelchair users to be installed below the indicator and the upper operating panel without drilling a new wiring hole in the hall wall. Furthermore, since the vertical length of the drawer opening can be easily increased in the portion facing the hall box, the operation wiring of the lower operating panel does not need to be sharply bent near the upper end of the drawer opening of the mounting plate. Furthermore, there is no need to fit a guide member for guiding the operation wiring of the lower operating panel into the drawer opening. This reduces the number of parts, prevents damage to the wiring, and simplifies installation. Furthermore, the increased flexibility in routing the operation wiring also simplifies installation.

[0013] In the elevator hall operating device according to the present invention, locking plate portions protruding from the back surface of the mounting plate may be provided at two positions spaced apart in the vertical or horizontal direction, and the locking plate portions may be configured to lock onto the inner surface of the hall box. This configuration makes it easier to secure the mounting plate to the hall wall compared to a configuration in which the mounting plate is secured to the hall box by screws.

[0014] In the elevator hall operating device according to the present invention, the indicator and the upper operating panel may be provided in an upper case, the lower operating panel may be provided in a lower case, the upper case and the lower case may be attached to the front side of the mounting plate at a distance from each other in the vertical direction, and the space between the front ends of the upper case and the lower case may be covered by a cover member on the front side of the mounting plate.

[0015] With this configuration, even if the height position of the upper case on which the indicator and upper operation panel are provided varies depending on the landing, and the vertical distance between the upper case and the lower case on which the lower operation panel is provided varies depending on the landing, the lower operation panel can be easily provided on the landing operating device while preventing deterioration of the appearance. In this case, it is only necessary to change the vertical length of the mounting plate and use a cover member with a vertical length appropriate for the landing. This allows the lower operation panel to be provided at a position that differs in distance from the upper operation panel depending on the state of the landing. Furthermore, there is no need to change the size of the upper case and the lower case depending on the landing.

[0016] In the elevator hall operating device according to the present invention, the indicator and the upper operation panel are provided on the upper case, the lower operation panel is provided on the lower case, the upper case is attached to the front side of the mounting plate, below the upper case on the front side of the mounting plate there are a plurality of lower case mounting positions at different distances from the upper case, the lower case is attached to some of the plurality of lower case mounting positions, and one or both of the space between the front side ends of the upper case and the lower case and the portion protruding below the lower end of the lower case on the front side of the mounting plate may be covered with a cover member.

[0017] This configuration allows the lower operating panel to be easily installed at different distances from the upper operating panel depending on the landing while minimizing deterioration of the appearance, without changing the size of the upper case, lower case, or mounting plate.

[0018] According to the elevator hall operating device of the present invention, the lower operating panel can be set below the indicator and the upper operating panel without drilling new wiring holes in the hall wall, and it is possible to suppress an increase in the number of parts, prevent damage to the wiring, and simplify the installation work.

[0020] The following describes an elevator hall operating device according to an embodiment of the present invention, using the drawings. The shapes, materials, numbers, positional relationships, etc. described below are examples for the purpose of explanation and can be changed as appropriate depending on the specifications of the elevator. In the following description, the same reference numerals are used to designate equivalent elements in all drawings.

[0021] Fig. 1 shows the vicinity of an elevator hall where a hall operating device 20 is installed. Fig. 2 is an enlarged view of part B in Fig. 1. Fig. 3A is a cross-sectional view taken along the line C-C in Fig. 2. Fig. 3B is a partially enlarged cross-sectional view showing the indicator device 21 and lower operating device 40 removed from Fig. 3A and the mounting plate 50 separated in the thickness direction, exaggerating the thickness of each device 21, 40. Fig. 4 shows the indicator device 21 and lower operating device 40 removed from Fig. 2.

[0022] In the elevator, a car moves up and down within a hoistway 110 provided in a building. The movement of the car is controlled by a control device. The elevator hall is provided with a hall door 114 that can be opened and closed to lead to a boarding / alighting entrance 112 provided in a hall wall 10 of the building. A hall operating device 20 is provided near the boarding / alighting entrance 112.

[0023] The hall operating device 20 is a device that allows a user to register a call by pressing a push button on the operating panel, and move the car to the floor where the user is located. When a user presses the up push button or the down push button on the operating panel, a signal indicating the call registration is output from the operating panel to a control device such as a machine room above the hoistway 110 via an operating wiring. One end of the operating wiring is connected to the operating panel, and the other end is connected to the control device through the hoistway 110. The control device registers a call for the car in response to the signal received from the operating panel, and controls the car to move to the floor where the user is located. The hall operating device 20 is also provided with an indicator that displays the position of the car, the planned direction of movement, etc.

[0024] In the hall operating device 20 of this example, a lower operating panel 41 exclusively for wheelchair users is provided below the upper operating panel 22 used by general users. This allows a wide range of users to use the hall operating device 20.

[0025] As shown in Figure 3A, a through opening 11 that opens to the elevator hall 115 and the hoistway 110 is provided in the landing wall 10 near the landing entrance 112. The landing operating device 20 includes the landing wall 10, a landing box 15 provided within the through opening 11, a mounting plate 50 fixed to the landing wall 10 while covering the landing-side opening of the through opening 11, and an indicator device 21 and a lower operating device 40 fixed to the mounting plate 50. The indicator device 21 has an indicator 24 and an upper operating panel 22 on which general users perform call registration operations. The lower operating device 40 is provided below the indicator device 21 and has a lower operating panel 41 on which wheelchair users perform call registration operations.

[0026] As shown in Figures 3A and 4, the landing box 15 has an opening at its landing side end and is a rectangular parallelepiped box fixed to the landing side end of the through-opening 11 (the left end in Figure 3A). As described above, the landing box 15 protects the housed electrical components such as wiring and connectors from external foreign objects. The landing box 15 is made of a metal such as iron or stainless steel. A box opening 17 is provided in the vertical middle part of the wall portion 16 at the far end of the landing box 15, for leading wiring such as operation wiring (described below) out of the landing box 15. As shown in Figure 3A, the box opening 17 may be provided with a packing 18 that allows wiring to pass through while preventing foreign objects such as water from entering the landing box 15.

[0027] As shown in Fig. 4, a plurality of screw holes 13 for screwing the indicator device 21 and the mounting plate 50 to the landing wall 10 are provided in the landing wall 10 near the open end of the landing box 15. As the screw holes 13, screw holes for fixing an existing indicator device that was attached to the landing wall 10 before the indicator device 21 may be used. In this case, it is not necessary to form new screw holes in the landing wall 10.

[0028] FIG. 5 shows the mounting plate 50 removed from FIG. 3A , viewed from the front side (a) and the side side (b). The mounting plate 50 covers the hall-side opening of the through-hole 11 and is fixed to the hall wall 10. The mounting plate 50 is a generally rectangular flat plate made of resin such as acrylic resin and has a thickness of approximately 5 mm. For example, the mounting plate 50 may have a thickness of 4.5 to 5.5 mm. Also, from the hall side, the indicator device 21 including the upper indicator 24 and the middle upper operation panel 22, and the lower operation device 40 including the lower lower operation panel 41, which are described below, are fixed to the mounting plate 50. In the following description, the elevator hall 115 side is referred to as the front side, and the hoistway 110 side is referred to as the back side. Furthermore, the horizontal direction when viewing the indicator 24 and each operation panel 22, 41 from the front side is referred to as the left-right direction.

[0029] The mounting plate 50 is provided with a drawer opening 51 penetrating in the thickness direction. The drawer opening 51 is an opening for passing indicator wiring of the indicator, upper operation wiring of the upper operation panel, and lower operation wiring of the lower operation panel.

[0030] The drawer opening 51 extends vertically from the vertical middle portion of the mounting plate 50 to the lower portion. Specifically, the drawer opening 51 extends vertically from a position corresponding to the landing box 15 and higher than the uppermost end P ( FIGS. 3A and 3B ) of the upper operation panel 22 to a position corresponding to the lower operation panel 41. This makes it possible to set the lower operation panel 41 below the indicator 24 and the upper operation panel 22 without drilling a new wiring hole in the landing wall 10 for passing the lower operation wiring 42 of the lower operation panel 41, as will be described later. Furthermore, it is possible to suppress an increase in the number of parts, prevent damage to the wiring, and facilitate installation work.

[0031] As described above, the mounting plate 50 is fixed to the landing wall 10. The indicator device 21 and the lower operating device 40 are fixed to the mounting plate 50 from the landing side. For this purpose, studs 54 fixed so as to protrude toward the landing side, screw through holes 55, and screw holes 56 are formed at multiple positions near the outer periphery of the mounting plate 50. In Figures 5(a) and 5(b), solid black circles or rectangles represent studs 54. Furthermore, the solid white circles in the range of arrow L1 in Figure 5(a) represent cylindrical screw through holes 55, and the solid white circles in the range of arrow L2 represent female-threaded screw holes 56.

[0032] The studs 54 are provided for passing through stud insertion holes (not shown) formed in an upper case 25 of the indicator device 21 and a lower case 44 of the lower operating device 40, which will be described later, for positioning. The screw through holes 55 are provided for screwing the mounting plate 50 together with the upper case 25 to the landing wall 10. The screw holes 56 are provided for screwing the lower case 44 to the mounting plate 50.

[0033] Further, the drawer opening 51 of the mounting plate 50 is provided with a wide portion 52 on the upper side and a narrow portion 53 on the lower side that is narrower in the left-right direction than the wide portion 52. The lower operating device 40 faces the lower end of the narrow portion 53. Providing the wide portion 52 in the drawer opening 51 makes it easier to draw multiple wires from the wide portion 52 toward the landing box 15.

[0034] In the mounting plate 50, above the drawer opening 51, a generally rectangular upper opening 58 is provided so as to penetrate through the mounting plate 50 in the thickness direction. This allows the mounting plate 50 to be made even lighter.

[0035] The indicator device 21 includes an indicator 24 and an upper operation panel 22 attached to a thin, generally rectangular upper case 25. As shown in FIG. 3B , the upper case 25 includes a flat, box-shaped base member 26 with an open front end, and a flat, box-shaped cover 27 fitted and fixed to the outer peripheral surface of the base member 26 and covering the open end of the base member 26. A case hole 28 is provided in a bottom plate 26a of the base member 26 for passing wiring 29, 30 for the indicator 24 and the upper operation panel 22 (described below). The case hole 28 is provided in a position facing the box opening 17 of the landing box 15 in the front-to-back direction, with the upper end of a drawer opening 51 (described below) interposed therebetween. Although not shown, the bottom plate 26a is also provided with stud insertion holes and screw through holes. A stud 54, which is part of the mounting plate 50, is inserted into the stud insertion hole in the bottom plate 26a. The screw through-holes in the bottom plate 26a are provided for fixing the indicator device 21 to the landing wall 10 with screws.

[0036] On the front side of the indicator device 21, the display surface of the indicator 24 is exposed from the upper part of the cover 27 of the upper case 25. On the front side of the indicator device 21, the upper push button and the lower push button of the upper operation panel 22 are exposed from the lower part of the cover 27.

[0037] The indicator device 21 is fixed to the mounting plate 50 in an upper mounting range (the range indicated by arrow L1 in FIG. 5( a) ) that extends from the upper end to the middle in the vertical direction. Specifically, the studs 54 in the upper mounting range of the mounting plate 50 are inserted into the stud insertion holes of the base member 26 in a fitted state. This positions the base member 26 on the mounting plate 50. In this state, screws that have passed through the screw through holes 55 in the upper mounting range of the base member 26 and the mounting plate 50 are screwed into the screw holes 13 in the landing wall 10. In this state, the cover 27 is fixed to the base member 26. In this way, the indicator device 21 is fixed to the landing wall 10 via the mounting plate 50.

[0038] Furthermore, the indicator wiring 29 connected to the indicator 24 and the upper operation wiring 30 connected to the circuit board of the upper operation panel 22 are drawn out to the landing box 15 through the case hole 28 of the base member 26 and the upper end of the drawer opening 51 of the mounting plate 50 facing this case hole 28. The indicator wiring 29 and the upper operation wiring 30 drawn out to the landing box 15 are drawn out to the hoistway 110 side of the through opening 11 through the box opening 17 at the far end of the landing box 15 together with the lower operation wiring 42 of the lower operation panel 41, as will be described later.

[0039] The lower operating device 40 has a lower operating panel 41 attached to a thin, generally rectangular lower case 44. Similar to the upper case 25, the lower case 44 includes a flat, box-shaped base member 45 with an open front end, and a cover 46 that is fitted and fixed to the outer periphery of the base member 45 and covers the open end of the base member 45. A case hole 48 is provided in the bottom plate 45a of the base member 45, through which the lower operating wiring 42 of the lower operating panel 41 passes. Although not shown, the bottom plate 45a also has stud insertion holes and screw through holes for securing the lower case 44 to the mounting plate 50. Studs 54 on the bottom of the mounting plate 50 are inserted into the stud insertion holes in the bottom plate 45a. The screw through holes in the bottom plate 45a are provided for screwing the lower operating device 40 to the mounting plate 50.

[0040] On the front side of the lower operating device 40, the upper push button and the lower push button of the lower operating panel 41 are exposed from the cover 46 of the lower case 44.

[0041] The lower operation device 40 is fixed to the mounting plate 50 in a lower mounting range (the range indicated by arrow L2 in FIG. 5A ) that is lower than the upper mounting range. Specifically, studs in the lower mounting range of the mounting plate 50 are inserted into the stud insertion holes in the base member 45 in a fitted state. This positions the base member on the mounting plate 50. In this state, screws that have passed through the screw through holes in the base member 45 are screwed into screw holes 56 in the lower mounting range of the mounting plate 50. In addition, the cover 46 is fixed to the base member 45.

[0042] As described above, the upper mounting range of the mounting plate 50 is fixed to the landing wall 10. As a result, the lower operating device 40 is fixed to the landing wall 10 via the mounting plate 50. In this state, the upper case 25 and the lower case 44 are attached to the mounting plate 50 in a state where they are closely adjacent to each other in the vertical direction. With this configuration, there is no need to form additional screw holes in the landing wall 10 in order to fix the lower operating device 40 to the landing wall 10.

[0043] Furthermore, lower operation wiring 42 connected to the circuit boards of the upper push buttons and the lower push buttons of the lower operation panel 41 is drawn out from a case hole 48 in the lower case 44 to a lower end of a drawer opening 51 in the mounting plate 50. The lower end of this drawer opening 51 faces the front side of the landing wall 10. In the drawer opening 51, the lower operation wiring 42 passes through a space portion sandwiched between the lower case 44 and the front side of the landing wall 10 and a space portion above that facing the opening of the landing box 15, and is drawn out from the upper part of the drawer opening 51 to the landing box 15.

[0044] The lower operation wiring 42 drawn out to the landing box 15, together with the indicator wiring 29 and the upper operation wiring 30, is drawn out to the hoistway 110 side of the through-opening 11 through a box opening 17 provided at the back end of the landing box 15. The lower operation wiring 42 is connected to a control device in a machine room or the like through the hoistway 110. At this time, the lower operation wiring 42 may be drawn out to the landing box 15 at approximately the same position as the indicator wiring 29 and the upper operation wiring 30, as shown by the solid line in FIG. 3A, or may be drawn out to the landing box 15 slightly below the draw-out positions of the indicator wiring 29 and the upper operation wiring 30, as shown by the dashed line in FIG. 3. At this time, the respective wirings 29, 30, 42 may be bundled with a bundling member or the like near the mounting plate 50 and drawn out to a position facing the box opening 17 of the landing box 15. In this case, it is easy to gather the respective wirings within the landing box 15 and guide them in a long, straight line to the box opening 17. This makes it easier to effectively utilize the space inside the landing box 15.

[0045] According to the above-described hall operating device 20, the mounting plate 50 is provided with a drawer opening 51 that extends vertically from a position that corresponds to the hall box 15 and that is higher than the top end of the upper operating panel 22 to a position that corresponds to the lower operating panel 41. In addition, the lower operation wiring 42 of the lower operating panel 41 is drawn out through the drawer opening 51 to the hall box 15. This makes it possible to set the lower operating panel 41 for wheelchair users below the indicator 24 and the upper operating panel 22 without drilling a new wiring hole in the hall wall 10.

[0046] Furthermore, because it is easy to increase the vertical length of the portion of the drawer opening 51 that faces the landing box 15, there is no need to sharply bend the lower operation wiring 42 of the lower operation panel 41 close to the upper end of the drawer opening 51 of the mounting plate 50. There is also no need to fit a guide member that guides the lower operation wiring 42 of the lower operation panel 41 into the drawer opening 51. This makes it possible to suppress an increase in the number of parts, prevent damage to the wiring, and facilitate installation work. Furthermore, the ability to increase the degree of freedom in handling the lower operation wiring 42 also facilitates installation work.

[0047] Furthermore, the drawer opening 51 is long in the vertical direction so as to include a portion facing the case hole 28 of the upper case 25. Therefore, the indicator wiring 29, the upper operation wiring 30, and the lower operation wiring 42 that have passed through the case hole 28 can be easily drawn out to a position facing the box opening 17 of the landing box 15 by binding them together with a binding member or the like near the mounting plate 50 while preventing damage to the wiring.

[0048] The mounting plate 50 is made of resin and has a thickness of about 5 mm. This allows the mounting plate 50 to be lightweight. The thickness of the mounting plate 50 can also be made larger than the outer diameter of commonly used wiring. Therefore, by providing the drawer opening 51 in the mounting plate 50 as described above, the lower operation wiring 42 can be passed from the inner lower portion of the drawer opening 51 to the upper portion and then drawn out from the drawer opening 51 more smoothly. Furthermore, since the thickness of the mounting plate 50 can be prevented from becoming excessively large, the overall thickness of the device including the mounting plate 50, the indicator device 21, and the lower operation device 40 can be reduced, thereby improving the design.

[0049] FIG. 6 is a diagram corresponding to FIG. 3A and shows a comparative example of a hall operating device 20a. The hall operating device 20a does not include a mounting plate 50 (FIGS. 3A, 3B, and 5), and the indicator device 21 and the lower operating device 40 are fixed directly to the hall wall 10. In this comparative example, there is no mounting plate with a drawer opening through which the lower operation wiring 42 passes, so it becomes necessary to drill a new wiring hole 116 in the hall wall 10 to lead the lower operation wiring 42 to the hoistway. This requires the difficult and time-consuming task of drilling the wiring hole 116 in the hall wall 10, and there is also the possibility that noise during construction may become a problem for residents and others. The embodiment shown in FIGS. 1 to 5 can prevent such inconveniences.

[0050] Fig. 7 is a view corresponding to Fig. 2, showing a hall operating device 20b according to another example of the embodiment. Fig. 8 is a view corresponding to the cross section D-D in Fig. 7, showing the hall operating device 20b in a state immediately before the cover member 60 is attached. Fig. 9 is a view (a) from the front side and (b) from the side, showing the state after the mounting plate 50a has been removed from Fig. 8 and the function expansion part 62 has been attached.

[0051] In the configuration of this example, the vertical length La (FIG. 9) of the mounting plate 50a is greater than that in the embodiment shown in FIGS. 1 to 5. That is, the vertical length La of the mounting plate 50 is greater than the sum (Lb + Lc) of the vertical length Lb of the upper case 25 and the vertical length Lc of the lower case 44 (La > Lb + Lc). The upper case 25 and the lower case 44 are attached to the front side of the mounting plate 50 (the front side in FIGS. 7 and 9(a), and the left side in FIGS. 8 and 9(b)) at a distance from each other in the vertical direction.

[0052] Furthermore, when the hall operating device 20b is viewed from the front side, the mounting plate 50a and the lower operation wiring 42 are visible between the upper case 25 and the lower case 44. For this reason, in this example, a cover member 60 is fitted between the front ends of the upper case 25 and the lower case 44 on the front side of the mounting plate 50a, thereby covering the space between the two cases 25, 44 with the cover member 60. The cover member 60 is formed, for example, from resin or the like in the shape of a rectangular parallelepiped or rectangular plate. Note that the cover member 60 may also be formed from resin or the like in the shape of a rectangular parallelepiped box having an opening at the back end and a closed front end. The cover member 60 may be fixed to the mounting plate 50 by adhesive or the like.

[0053] As a result, the height position of the upper case 25 varies depending on the landing, in accordance with the height position of the landing box 15, so that even if the vertical distance between the upper case 25 and the lower case 44 varies depending on the landing, the lower operation panel 41 can be easily provided on the landing operating device 20b while preventing deterioration of the appearance. In this case, it is only necessary to change the vertical length of the mounting plate 50a and use a cover member 60 with a vertical length appropriate for the landing. This makes it possible to provide the lower operation panel 41 at a position that differs in distance from the upper operation panel 22 depending on the landing. Furthermore, there is no need to change the sizes of the upper case 25 and the lower case 44 depending on the landing.

[0054] 8 and 9(b), in this example, locking plates that protrude toward the back side are provided at two vertically spaced positions on the back surface of the mounting plate 50a. Specifically, metal fittings 64 with a generally L-shaped cross section are fixed to two vertically spaced positions on the back surface of the mounting plate 50a. The metal fittings 64 have a fixing plate 65 that is fixed along the mounting plate 50a, and a locking plate 66 that is bent at a substantially right angle from one vertical end of the fixing plate 65 and extends toward the back side.

[0055] The metal fittings 64 are fixed to the mounting plate 50a by, for example, screwing the fixing plate portions 65 to two positions on the back surface of the mounting plate 50a that are spaced apart in the vertical direction. In this state, the locking plate portions 66 of the two metal fittings 64 protrude to the back surface from opposite ends that are spaced apart in the vertical direction. The vertical length of the upper end of the upper metal fitting 64 and the lower end of the lower metal fitting 64 is made to approximately match the vertical length of the opening of the landing box 15. Then, the back surface of the mounting plate 50 is pressed against the landing wall 10, and the two metal fittings 64 are fitted into two positions, one above the other, on the inner surface of the opening end of the landing box 15, so that the locking plate portions 66 are locked to the inner surface of the landing box 15. In this way, the mounting plate 50a is fixed to the landing box 15.

[0056] For example, before the mounting plate 50a is fitted into the landing box 15, the locking plate portions 66 of the two metal fittings 64 fixed to the mounting plate 50a may be bent so that the distance between them increases toward their tips. In this state, the two locking plate portions 66 are pushed into the inner surface of the open end of the landing box 15 while the distance between the rear ends of the locking plate portions 66 of the two metal fittings 64 is elastically reduced, whereby the mounting plate 50a is fixed to the landing box 15 by the elastic force of the metal fittings 64.

[0057] This makes it easier to fix the mounting plate 50a to the landing wall 10 compared to a configuration in which the mounting plate is fixed to the landing box 15 by screw connection. The locking plate portion may be made of resin and formed integrally with the mounting plate, as a plate portion that protrudes to the back side. Furthermore, although not shown, a configuration may also be adopted in which locking plate portions that protrude to the back side are provided at two positions spaced apart in the left-right direction on the back surface of the mounting plate 50, and each locking plate portion is locked to both left-right ends of the inner surface of the opening end of the landing box 15.

[0058] Furthermore, as shown in FIG. 9 , a function expansion part 62 is attached to the back side of the mounting plate 50a by screw connection or the like. The function expansion part is not shown in FIG. 8 . The function expansion part 62 is, for example, a speaker, and is connected by wiring to a control device provided in a machine room or the like. The speaker outputs a sound or voice to notify users near the landing of information such as the arrival of a car or the detection of an abnormality in accordance with an output command signal output from the control device. The function expansion part 62 may be any part for expanding the function of the hall operating device 20, and is not limited to only a speaker, but may also be a speaker and a circuit board, or only a circuit board, etc. The function expansion part 62 is disposed inside the hall box 15. By attaching the function expansion part 62 to the back side of the mounting plate 50 in this way, the function of the hall operating device 20b can be expanded without attaching a function expansion part to the upper case 25 fixed to the hall wall 10 or the inner surface of the hall box 15. This prevents the thickness of the upper case 25 from increasing, and eliminates the need for difficult parts mounting to the landing box 15. In this example, the other configurations and functions are the same as those in FIGS.

[0059] 10 shows three states in which the mounting position of the lower operating device 40a relative to the mounting plate 50b is different in a hall operating device 20c according to another example of the embodiment. In this example, similar to the configurations in FIGS. 7 to 9, the vertical length of the mounting plate 50b is greater than the total length (La + Lb) of the vertical length La of the upper case 25 and the vertical length Lb of the lower case 44a.

[0060] The front side of the mounting plate 50b has a plurality of lower case mounting positions below the upper case 25, each positioned at a different distance from the upper case 25. The lower case 44a is mounted at some of the plurality of lower case mounting positions. Specifically, screw through holes are provided at both left and right ends of the base member of the lower case 44a. The base member is mounted to the mounting plate 50b by threading screws that pass through the screw through holes into the screw holes in the mounting plate 50b. At this time, the mounting plate 50b has a greater number of screw holes 56 than the number of screw through holes 68 in the base member of the lower case 44a at both left and right ends below the mounting surface of the upper case 25.

[0061] In FIG. 10 , dashed circles indicate screw holes 56 on the mounting plate 50b. Solid circles with an X inside indicate screw through-holes 68 in the base member of the lower case 44a. Because the screw through-holes 68 are provided in the base member, they are not actually visible from the front side of the lower case 44a. This allows the lower case 44a to be attached to the front side of the mounting plate 50b, below the upper case 25, at one of multiple lower case attachment positions at different distances from the upper case 25. In FIG. 10( a ), the lower case 44a is attached to the lowest end of the mounting plate 50b. In FIG. 10( b ), the lower case 44a is attached to the mounting plate 50b close to the bottom end of the upper case 25. In FIG. 10( c ), the lower case 44a is attached to the mounting plate 50b at an intermediate position between FIGS. 10( a ) and 10( b ).

[0062] Furthermore, on the front side of the mounting plate 50b, a cover member covers either or both of the space between the front ends of the upper case 25 and the lower case 44a and the portion that protrudes downward from the lower end of the lower case 44a. For example, in Fig. 10(a) , on the front side of the mounting plate 50b, a cover member covers the space between the front ends of the upper case 25 and the lower case 44. The configuration of the cover member and its attachment to the mounting plate 50 are similar to the configurations shown in Figs. 7 and 8.

[0063] 10(b), one or both of the portions of the front side of the mounting plate 50b that protrude downward from the lower end of the lower case 44 are covered by cover members 60, 60a, and 60b. In Fig. 10(c), two cover members 60a and 60b cover both the portion of the front side of the mounting plate 50b between the upper case 25 and the front end of the lower case 44a and the portion of the front side of the mounting plate 50b that protrudes downward from the lower end of the lower case 44a. The configuration of the two cover members 60a and 60b is the same as the configuration of the cover member 60 used in Figs. 10(a) and 10(b), except for the vertical length.

[0064] According to the configuration of this example, the lower operating panel 41 can be easily installed at different distances from the upper operating panel 22 depending on the landing while minimizing deterioration of the appearance. In this case, there is no need to change the sizes of the upper case 25, the lower case 44a, and the mounting plate 50b. Alternatively, the mounting plate 50b may have only the two lower case mounting positions shown in FIGS. 10(a) and 10(b), and the lower case 44a may be mounted at a mounting position selected from only the two lower case mounting positions. In this example, the other configurations and operations are the same as those of the configurations of FIGS. 1 to 5 or the configurations of FIGS. 7 to 9.

[0065] In the above embodiment, the case has been described in which the lower operation wiring, the upper operation wiring, and the indicator wiring are passed through the drawer openings 51 provided in the mounting plates 50, 50a, 50b and drawn out to the landing box 15. On the other hand, a configuration may be adopted in which a second drawer opening through which the upper operation wiring and the indicator wiring are passed is provided in the mounting plate, in addition to the first drawer opening through which the lower operation wiring is passed. Even in this case, by configuring the first drawer opening to extend long in the vertical direction from a position corresponding to the landing box 15 and higher than the top end of the upper operating panel to a position corresponding to the lower operating panel, it is possible to suppress an increase in the number of parts, prevent damage to the wiring, and facilitate installation work.
