FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] An elevator 10 according to one embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of a hoistway 12 of the elevator 10. FIG. 2 is a functional block diagram centered on a control panel 40. As shown in FIGS. 1 and 2, the elevator 10 includes a car 20 and a counterweight 21 suspended movably in the vertical direction within the hoistway 12 via a steel main rope 11, a first fixed pulley 13A, a second fixed pulley 13B, and a hoist M. The first fixed pulley 13A and the second fixed pulley 13B are attached to supports FL1 and FL2, respectively, which are fixed to a beam 12A located at a top 12T, which is the uppermost portion of the hoistway 12.

[0014] In addition, in the elevator 10 of this embodiment, the main rope 11 is stretched so that the speed ratio (roping ratio) between the hoisting speed of the sheave M1 provided in the hoisting machine M and the lifting speed of the car 20 is 2:1. Specifically, one end of the main rope 11 is fixed via a hitch BL1 to a support frame FL3 provided near the top 12T of the hoistway 12, and hangs down directly downward and spans a pair of under-car pulleys 20a, 20b provided at the bottom of the car 20, a first fixed pulley 13A installed at the top 12T of the hoistway 12, a sheave M1 of the hoisting machine M fixed directly above a pit 12P in the hoistway 12, a second fixed pulley 13B at the top 12T of the hoistway 12, and a pulley 21a provided at the top of the counterweight 21, in this order, with the other end connected and fixed to a beam 12A of the hoistway 12 via a hitch BL2. In this embodiment, the under-car pulleys 20a, 20b of the car 20 function as movable pulleys.

[0015] In this embodiment, the hoisting machine M is positioned slightly above the pit 12P of the elevator shaft 12 as part of measures to prevent flooding during floods, etc., but it may also be positioned within the pit 12P or elsewhere within the elevator shaft 12.

[0016] The elevator 10 includes a control panel (storage box) 40 that controls the overall operation of the car 20. The control panel 40 is installed at the top 12T of the elevator shaft 12, i.e., on the wall of the elevator shaft 12 located slightly above the top floor landing 14A. In this embodiment, the control panel 40 is installed slightly above the top floor landing 14A, but the present invention is not limited to this. For example, the control panel 40 may be installed at a position higher than the pit 12P of the elevator shaft 12, specifically, slightly above the landing 14 on an intermediate floor or the lowest floor.

[0017] As shown in Fig. 1, the car 20 has a car door 22. On the other hand, hall doors 16A, 16B, 16C, ... (hereinafter, when there is no particular need to distinguish between them, they will be referred to as hall doors "16") are provided at halls 14A, 14B, 14C, ... (hereinafter, when there is no particular need to distinguish between them, they will be referred to as hall doors "16").

[0018] Each landing door 16 is constantly biased in the direction of closing the door via an elastic member such as a spring, and is held in a closed state via locking mechanisms 17A, 17B, 17C, ... (hereinafter, when there is no particular need to distinguish between them, they will be referred to as locking mechanisms "17" as appropriate) attached to the upper part. Each landing door 16 is arranged so that it is released from being fixed by the locking mechanism 17 and can be opened only when the above-mentioned car 20 is stopped at a preset landing position, that is, at a position where the vertical position of the floor of the space inside the car of the car 20 approximately coincides with the vertical position of the floor of the landing 14 where passengers can get on and off the car 20 via the landing door 16 (in other words, a position where the landing door 16 and the car door 22 face each other).

[0019] The locking mechanism 17 is also provided with door opening sensors 18A, 18B, 18C, ... (hereinafter, when there is no particular need to distinguish between them, they will be referred to as door opening sensors "18") that have the function of detecting the open / closed state of the landing door 16.

[0020] As shown in Fig. 1, an on-car operation unit 26 is provided on the car top 20T on the roof of the car 20. The on-car operation unit 26 includes a switching operation unit 27 (see Fig. 2) for performing an operation to switch the operation mode of the car 20 from a normal operation mode (described later) to manual operation, and a lifting / lowering operation unit 28 (see Fig. 2) for performing an operation to lift / lower the car 20 during manual operation. This allows the car 20 to be lifted / lowered with a maintenance worker on top of the car 20 during maintenance and inspection.

[0021] As shown by the dashed line in Fig. 1, a safety fence 70 is installed on the outer periphery of the car upper part 20T, which serves as a foothold for maintenance personnel during maintenance and inspection. This safety fence 70 is, for example, a prefabricated fence that is installed along the outer periphery of the car upper part 20T only during maintenance and inspection. Then, when maintenance and inspection are completed, the safety fence 70 is removed from the outer periphery of the car upper part 20T and stored in a predetermined location on the car upper part 20T.

[0022] As shown in FIG. 2, the control panel 40 includes a storage device 43 including a ROM, a RAM, an HDD, and the like in which various control programs are stored, and an arithmetic processing device (not shown) such as a CPU, and functions as an operation control unit 44 that controls the drive of the hoisting machine M by reading the control programs from the storage device 43 and performing arithmetic processing, and a door monitoring unit 46 that detects the open / closed state of the landing door 16 via the door open sensor 18 described above.

[0023] The operation control unit 44 is configured to execute a normal operation mode in which the car 20 is raised or lowered (moved) to each floor landing 14 based on a landing call made via the landing operating panels 15A, 15B, 15C, ... (hereinafter, when there is no need to distinguish between them, the landing operating panels will be referred to as "15" as appropriate) installed at the landings 14 on each floor, and a destination floor operation made via the car operating panel 24 installed inside the car 20, in other words, a car call operation.

[0024] The car operation panel 24 (see Figure 2), like the car on-board operation unit 26 described above, also has the function of switching the operation mode of the car 20 from the normal operation mode described below to manual operation, and of operating the car 20 to raise and lower during manual operation.

[0025] The operation control unit 44 also has a prohibition mode that prohibits the execution of the normal operation mode described above. This prohibition mode is executed when the opening of the hall door 16 is detected via the door monitoring unit 46 in a state where the car 20 has not stopped (landed) at a preset landing position when the car 20 stops at the hall 14, in other words, has not stopped (landed) at a position facing the hall door 16.

[0026] Here, the car 20 is fitted with a floor position detection unit 45 having a function of detecting the position of the car 20. This floor landing position detection unit 45 has a function of detecting a light blocking plate (not shown) provided on the wall surface of the elevator shaft 12 corresponding to each landing 14. This enables the operation control unit 44 to determine whether or not the car 20 is positioned at a preset floor landing position.

[0027] Next, the configuration of the control panel 40 will be described with further reference to Figures 3(a) and 3(b). Figure 3(a) is a diagram showing the front configuration of the control panel 40, and Figure 3(b) is a diagram showing the configuration of the rear side of the slide cover 52 included in Figure 3(a).

[0028] 3(a) and 3(b), the control panel 40 has a housing (box body) 50 having a generally vertically long box-like appearance, a slide cover 52 that covers a front opening 50a (see FIG. 5(a)) provided directly below an upper panel 51d that covers the upper front of the housing 50, and a guide unit 54 that slides the slide cover 52 up and down. The housing 50 stores equipment to be maintained 53 (see FIG. 5(a)) that is made up of various electronic devices for controlling the elevation and lowering of the car 20.

[0029] 3(b), the slide cover 52 is a metal panel having a generally rectangular shape when viewed from the front, and is fixed to the housing 50 with its upper end 52u inserted inside the upper panel 51d. The slide cover 52 has identically configured daruma holes H1 to H4 (hereinafter referred to as "daruma holes H" when no particular distinction is required) at both the top, bottom, left and right ends, and identically configured slits SL1 and SL2 (hereinafter referred to as "slits SL" when no particular distinction is required) at both the left and right ends of the lower end.

[0030] The potbellied holes H1 to H4 of the sliding cover 52 are through holes for fixing the sliding cover 52 to the side surfaces 51a and 51b of the housing 50 using bolts BT1 to BT4. Slits SL1 and SL2 are provided at both ends of the lower end of the sliding cover 52. These slits SL1 and SL2 are holes for fixing the lower end of the sliding cover 52 to the bottom 51c of the housing 50 via bolts BT5 and BT6. The sliding cover 52 is fixed to the housing 50 by bolts BT1 to BT6 (hereinafter simply referred to as "bolt BT" when no distinction is required) inserted into the potbellied holes H1 to H4 and the slits SL1 and SL2, respectively.

[0031] Furthermore, sliding portions 52a and 52b that movably engage with the above-mentioned guide unit 54 are provided on both left and right ends of the upper end of the slide cover 52. Here, both sliding portions 52a and 52b have the same configuration except for being provided symmetrically, so in the following explanation, sliding portion 52b will be mainly explained, and explanation of sliding portion 52a will be omitted as appropriate. This sliding portion 52b is configured by being bent into a substantially U-shape as shown in Figure 3(c).

[0032] The configuration of the guide unit 54 will now be described with reference to Figures 4(a) to 4(c). Figure 4(a) is a diagram showing the side configuration of the housing 50 when the sliding cover 52 is closed, i.e., when the sliding cover 52 is in a covering position that blocks the front opening 50a (see Figure 5(a)) of the housing 50. Figure 4(b) is a diagram showing the side configuration of the housing 50 when the sliding portions 52a and 52b of the sliding cover 52 are lowered to a position where they abut against the bottom 51c of the housing 50, i.e., when the housing 50 is in an open position. Similarly to Figure 4(b), Figure 4(c) is a diagram showing the position of the movable bracket 62 when the sliding cover 52 is removed from the housing 50.

[0033] As shown in Figures 4(a) to 4(c), the guide unit 54 includes a left guide portion 56a (see Figures 5(a) and 5(b)) provided at the left end of the housing 50, and a right guide portion 56b provided at the right end of the housing 50. The right guide portion 56b and the left guide portion 56a have almost the same configuration except that they are provided symmetrically at both the left and right ends of the housing 50, and therefore, in the following explanation, only the configuration of the right guide portion 56b will be mainly explained, and explanation of the left guide portion 56a will be omitted as appropriate.

[0034] The right guide portion 56b includes a guide bracket 61 and a movable bracket (removal restricting portion) 62 attached to the right end portion of the housing 50, and has the function of guiding the sliding portion 52b provided on the right end portion of the slide cover 52 in the up and down direction between the open position and the closed position described above. As shown in FIG. 4(a), the guide bracket 61 has a generally U-shaped cross section and is a member that functions as a guide rail together with the movable bracket 62 described below, and is a long metal member that extends along the up and down direction of the housing 50.

[0035] Fig. 4(d) is a diagram showing the cross-sectional configuration when cut along line BB shown in Fig. 4(a). In Fig. 4(d), cross-sectional hatching is omitted to avoid complication. As shown in Fig. 4(d), the sliding portion 52b of the slide cover 52 is engaged with the guide bracket 61 so as to be movable in the up and down direction.

[0036] Furthermore, the movable bracket 62 disposed directly below the guide bracket 61 has a substantially U-shaped cross section similar to the guide bracket 61, and serves to guide the sliding portion 52b in the vertical direction. As shown in Fig. 4(b), this movable bracket 62 is attached to the side portion 51b of the housing 50 so as to be slidable in the vertical direction by loosening bolts BT7 and BT8 (hereinafter, referred to as "bolts BT" as appropriate when there is no particular need to distinguish between them) exposed to the outside with the sliding cover 52 lowered to the lowest end of its movable range, that is, to the open position where the sliding portion 52b of the sliding cover 52 abuts against the bottom portion 51c of the housing 50.

[0037] Here, Figure 5(a) is a diagram showing the configuration of the housing 50 when the movable bracket 62 is positioned in the removal restriction position P1, and Figure 5(b) is a diagram showing the configuration of the housing 50 when the movable bracket 62 is positioned in the removal position P2.

[0038] 5(a) and 5(b), movable bracket 62 is fixed to side surface 51b of housing 50 via fixing bolts BT7 and BT8 inserted through elongated holes 62a provided in the center. These elongated holes 62a serve to fix movable bracket 62 to side surface 51b of housing 50 so that it can move between a removal restricted position P1, where the upper end of movable bracket 62 abuts against the lower end of guide bracket 61, and a removal permitted position P2 that is lower than removal restricted position P1, when the fixing bolts BT7 and BT8 are loosened.

[0039] When the movable bracket 62 is positioned at the removal restriction position P1, a gap D1 is formed between the movable bracket 62 and the guide bracket 61. In contrast, when the movable bracket 62 is positioned at the removal position P2, the gap between the movable bracket 62 and the guide bracket 61 expands to gap D2. Here, the relationship between the size of the above-mentioned gaps D1, D2 and the vertical dimension L of the sliding portion 52b (see FIG. 4(b)) is set to satisfy the relationship of the following formula (1).

[0040] D1 <L<D2···(1) As a result, when the movable bracket 62 is positioned at the removal position P2, the sliding portion 52b of the sliding cover 52 can be removed from the movable bracket 62 (see FIG. 4(c)). On the other hand, when the sliding portion 52b is positioned at the removal restriction position P1, the sliding portion 52b cannot be removed from the right guide portion 56b (see FIG. 4(b)). This prevents the sliding cover 52 from falling off the housing 50.

[0041] Furthermore, a screw hole (fixing portion) 62b for fixing the slide cover 52 is provided at the lower end of the movable bracket 62. This screw hole 62b is a screw hole for fixing the slide cover 52 with a bolt BT, and is provided at a position that overlaps with a potbellied hole H4 (see FIG. 3(a)) provided at the lower end of the slide cover 52 when the slide cover 52 is in the shielding position.

[0042] 3(b), the potbelly hole H4 is composed of an elongated slot portion H4-1 provided at the top and a round hole portion H4-2 provided below the slot portion H4-1 and wider than the slot portion H4-1. The slot portion H4-1 of the potbelly hole H4 is configured so that the sliding cover 52 can be fixed to the side surface portion 51b of the housing 50 by screwing in the bolt BT described above. On the other hand, the round hole portion H4-2 of the potbelly hole H4 is wider than the diameter of the bolt BT and therefore cannot be used to fix the sliding cover 52 to the side surface portion 51b of the housing 50.

[0043] 6(a) is a diagram showing how the potbellied hole H4 and the screw hole 62b in the movable bracket 62 overlap when the sliding cover 52 is moved to the shielding position with the movable bracket 62 fixed at the removal restricted position P1. FIG. 6(b) is a diagram showing how the potbellied hole H4 and the screw hole 62b in the movable bracket 62 overlap when the sliding cover 52 is moved to the shielding position with the movable bracket 62 positioned at the removal permitted position P2 below the removal restricted position P1.

[0044] 6(a) and 6(b), when the movable bracket 62 is located in the removal restricted position P1, the elongated hole portion H4-1 of the potbellied hole H4 of the sliding cover 52 overlaps with the screw hole 62b of the movable bracket 62, so the sliding cover 52 can be fixed via the bolt BT. On the other hand, when the movable bracket 62 is located in the removal enabled position P2, the round hole portion H4-2 of the potbellied hole H4 overlaps with the screw hole 62b of the movable bracket 62, so the sliding cover 52 cannot be fixed via the bolt BT.

[0045] For this reason, when removing and replacing the sliding cover 52, the sliding cover 52 cannot be attached unless the movable bracket 62 is returned from the removal position P2 to the removal restriction position P1 and fixed there. This makes it necessary to fix the movable bracket 62 to the removal restriction position P1 in advance in order to complete the task of fixing the sliding cover 52 to the housing 50 via the movable bracket 62. As a result, it is possible to prevent forgetting to return the movable bracket 62 to the removal restriction position P1.

[0046] Next, the procedure for performing the maintenance and inspection work on the control panel 40 described above by two maintenance personnel will be described with further reference to Fig. 7. Fig. 7 is a diagram that schematically shows how the maintenance and inspection work on the control panel 40 is performed while the maintenance personnel are aboard the car upper section 20T of the car 20. As shown in Fig. 7, in order for one maintenance personnel to board the car upper section 20T from the top floor landing 14A (see Fig. 1), the other maintenance personnel who has already boarded the car 20 operates the car operating panel 24 to switch the operation mode from the normal operation mode to the manual operation mode, and raises or lowers the car 20 to a position where the one maintenance personnel waiting at the top floor landing 14A (see Fig. 1) can board the car upper section 20T of the car 20.

[0047] Next, one of the maintenance personnel waiting at the top floor landing 14A uses a special tool to open the landing door 16A (see FIG. 1), enters the car upper section 20T, and switches to manual operation via the switching operation unit 27 (see FIG. 2) in the car upper operation unit 26. Then, as shown by the dashed line in FIG. 1, he assembles and installs the safety fence 70 that has been pre-loaded on the car upper section 20T.

[0048] 7 is a diagram schematically illustrating a state in which a maintenance worker performs maintenance and inspection work on the control panel 40 while riding in the car upper section 20T of the car 20. As shown in FIG. 7, the car 20 is manually raised and lowered to a position close to the control panel 40 via the lifting and lowering operation unit 28 (see FIG. 2) of the car upper operation unit 26 (see FIG. 2).

[0049] Then, the bolts BT (see FIG. 3(a)) that secure the sliding cover 52 of the control panel 40 shown in FIG. 7 to the housing 50 are removed, and the sliding cover 52 that covers the opening 50a at the bottom of the front side of the control panel 40 is slid from the closed position shown by the solid line in FIG. 7 to the open position shown by the dashed line. At this time, the sliding cover 52 slides up and down, so it can be opened and closed without hitting the safety fence 70 installed on the car top 20T. Furthermore, the movable bracket 62 that guides the sliding parts 52a, 52b (see FIG. 4(b)) of the sliding cover 52 up and down is positioned at the removal restriction position P1, so the sliding cover 52 will not fall off.

[0050] Furthermore, when removing the slide cover 52 from the control panel 40, as shown in FIG. 4(b), the bolts BT that secure the movable bracket 62 (see FIG. 5(a)) of the right guide portion 56b to the side portion 51b of the housing 50 are loosened, and the movable bracket 62 is slid downward from the removal restricted position P1 to the removal permitted position P2. Similarly, the bolts that secure the movable bracket 64 (see FIG. 5(a)) of the left guide portion 56a are loosened, and the movable bracket 64 is slid downward. The movable bracket 64 corresponds to the removal restricted portion.

[0051] 4(c), the slide cover 52 is lifted slightly and the sliding portion 52b of the slide cover 52 is moved from the position indicated by the dashed line to the position indicated by the solid line through the gap D2 (see FIG. 5(b)) between the guide bracket 61 and the movable bracket 62, thereby removing it from the movable bracket 62. Similarly, the sliding portion 52a is also removed from the gap between the guide bracket 63 (see FIG. 5(b)) of the left guide portion 56a and the movable bracket 64. This completes the removal of the slide cover 52.

[0052] As described above, even when the movable brackets 62, 64 are moved to the removal position P2, the slide cover 52 cannot be removed unless the slide cover 52 is lifted slightly and the sliding portions 52a, 52b are removed from the gaps D2 between the movable brackets 62, 64 and the guide brackets 61, 63. This prevents the slide cover 52 from being accidentally dropped during the removal process.

[0053] Next, to attach the slide cover 52, as shown in FIG. 4(c), the slide portion 52b of the slide cover 52 is inserted between the guide bracket 61 and the movable bracket 62 and set to a position where it abuts against the bottom 51c of the housing 50, as shown by the dashed line in FIG. 4(c). Similarly, the slide portion 52a of the slide cover 52 is inserted between the guide bracket 63 and the movable bracket 64 and set to a position where it abuts against the bottom 51c of the housing 50. In this state, the movable bracket 62 of the right guide portion 56b is moved upward from the removal position P2 to the removal restricted position P1, and the bolt BT is tightened to secure it. Similarly, the movable bracket 64 of the left guide portion 56a is also moved to the removal restricted position and secured therein.

[0054] Thereafter, the slide cover 52 shown in Fig. 4(a) is slid upward, and the upper end 52u of the cover 52 is inserted into the inside of the upper panel 51d while being moved to the shielding position. Then, as shown in Fig. 3(a), the slide cover 52 is fixed using each bolt BT. This completes the installation and removal work of the slide cover 52.

[0055] According to the control panel 40 of this embodiment, the sliding cover 52 can be removed by positioning the movable bracket 62 in the removal position P2. This allows the sliding cover 52 to be removed from the housing 50 for replacement or repair work. As a result, the workload for maintenance and inspection work can be reduced.

[0056] The present invention can be implemented in various forms, including improvements, modifications, and variations based on the knowledge of those skilled in the art, without departing from the spirit of the invention.
