Each landing entrance 5 is opened and closed by a landing door. The car entrance 3 and the landing entrance 5 face each other as shown in FIG. 1 when the hoistway 1 is viewed from above. When the car 2 is stopped on the floor, the car entrance 3 and the hall entrance 5 facing each other are opened at the same time, so that passengers can get on and off between the hall 4 and the car 2 at the stop floor of the car 2. Become.

  The operation of the elevator is controlled by a control device (not shown) installed in the hoistway 1. The elevator operation can be switched between a normal operation mode in which normal service operation is performed and a maintenance operation mode in which the car 2 is moved at a lower speed than in the normal operation mode.

  In the elevator, an operator may perform maintenance and inspection work on the equipment in the hoistway 1 while the worker is on the upper surface 2 a of the car 2. On the upper surface 2 a of the car 2, an on-car maintenance operation unit (not shown) is provided. An operator who rides on the upper surface 2a of the car 2 operates the on-car operation unit during maintenance in the maintenance operation mode in order to move the car 2 at a low speed.

  The operator stops the car 2 by aligning the height of the upper surface 2a of the car 2 with the height of the floor of the hall 4 on the top floor, and passes through the hall entrance 5 from the hall 4 on the top floor. It is possible to get on the upper surface 2a. Therefore, the space part which opposes the landing doorway 5 among the space which exists above the cage | basket | car 2 is made into the ceiling entrance through which an operator passes at the time of boarding to the upper surface 2a of the cage | basket | car 2. That is, the ceiling entry port is a space portion existing in a certain range above the car doorway 3 in the space existing above the car 2.

  A car upper handrail device 6 is provided on the upper part of the car 2. The car upper handrail device 6 includes a pair of side handrails 7 and 8 and a rear handrail 9.

  The pair of side handrails 7 and 8 are disposed on both sides in the width direction of the ceiling entrance. The pair of side handrails 7 and 8 are disposed along the depth direction of the car 2.

  The side handrails 7 and 8 are provided so as to be displaceable at a fixed handrail member 12 fixed to the upper part of the car 2 in a state of protruding upward from the upper surface 2 a of the car 2 and an upper end portion of the fixed handrail member 12. And a movable handrail member 13.

  The fixed handrail member 12 of one side rail 7 is disposed along one side 2d of the car 2 when viewed from above. The fixed handrail member 12 of the other side rail 8 is disposed along the other side 2d of the car 2 when viewed from above. Each fixed handrail member 12 includes a plurality of vertical angle members fixed to the upper surface 2a of the car 2, and a horizontal angle member fixed to the plurality of vertical angle members. Moreover, the height from the upper surface 2a of the cage | basket | car 2 to the upper end part of the fixed handrail member 12 is the height within the range of 400 mm-700 mm.

  The movable handrail member 13 is rotatably attached to the upper end portion of the fixed handrail member 12 via an attachment shaft 14 along the depth direction of the car 2. In addition, the movable handrail member 13 includes a plurality of vertical angle members that can rotate around the axis of the mounting shaft 14 and a horizontal angle member that is fixed to the plurality of vertical angle members. Furthermore, the movable handrail member 13 is rotated about the axis of the mounting shaft 14, so that the standing position where the movable handrail member 13 stands on the upper end portion of the fixed handrail member 12 and the upper hand end portion of the fixed handrail member 12 fall down. It can be displaced between positions.

  The rear handrail 9 includes a fixed handrail member 21 fixed to the upper part of the car 2 in a state of protruding upward from the upper surface 2 a of the car 2, and a movable handrail member provided displaceably at the upper end of the fixed handrail member 21. 22. The fixed handrail member 21 of the rear handrail 9 is disposed along the rear face 2c of the car 2 when viewed from above. In this example, the height from the upper surface 2 a of the car 2 to the upper end portion of the fixed handrail member 21 is lower than the height of the respective fixed handrail members 12 of the side handrails 7 and 8.

  The movable handrail member 22 of the back handrail 9 is rotatably attached to the upper end portion of the fixed handrail member 21 via an attachment shaft 23 along the width direction of the car 2. The movable handrail member 22 is rotated about the axis of the mounting shaft 23, thereby standing up at the upper end portion of the fixed handrail member 21, and falling over when tilted with respect to the upper end portion of the fixed handrail member 21. It is possible to displace between. The falling position of the movable handrail member 22 of the rear handrail 9 is lower than the falling position of the movable handrail member 13 of each of the side handrails 7 and 8. FIGS. 1 and 2 show a state where the movable handrail members 13 and 22 of the side handrails 7 and 8 and the back handrail 9 are in the fall position.

  The state of the car upper handrail device 6 becomes an assembly state when the movable handrail members 13 of the side handrails 7 and the movable handrail member 22 of the rear handrail 9 reach the standing position, and the movable handrails of the respective side handrails 7 are brought into an assembled state. When the movable handrail member 22 of the member 13 and the rear handrail 9 reaches the fall position, the folded state is reached.

  FIG. 3 is a top view showing an upper portion of the car 2 when the state of the car handrail device 6 of FIG. 1 is an assembled state. FIG. 4 is a front view showing the upper part of the car 2 of FIG. When the position of the movable handrail member 13 of each of the side handrails 7 and 8 reaches the upright position, as shown in FIG. Up to the maximum height. In this example, when each movable handrail member 13 is in the upright position, the height from the upper surface 2a of the car 2 to the respective upper end portions of the side handrails 7 and 8 is 850 mm or more.

  Further, when the position of the movable handrail member 22 of the rear handrail 9 becomes the standing position, the height from the upper surface 2a of the car 2 to the movable end portion, that is, the upper end portion of the rear handrail 9 is maximized. In this example, when the movable handrail member 22 is in the standing position, the height from the upper surface 2a of the car 2 to the upper end of the rear handrail 9 is 850 mm or more.

  The movable handrail members 13 of the side handrails 7 and 8 reach the fall position by falling from the standing position to the ceiling entrance side, that is, the inside of the car 2. Further, when the movable handrail member 13 of each of the side handrails 7 and 8 is in the collapsed position, as shown in FIG. 2, the movable handrail member 13 is positioned at the intermediate portion in the height direction of the ceiling entrance, and The ceiling entrance is horizontally traversed while facing each other in the width direction. Accordingly, the movable handrail member 13 prevents the operator from getting on the upper surface 2a of the car 2 from the landing 4.

  The distance between the movable end portions of each movable handrail member 13 is continuously reduced as each movable handrail member 13 is displaced from the standing position to the fall position. In this example, the movable end portions of the movable handrail members 13 when in the tilted position are opposed to each other via a space, and the distance between the movable end portions of the movable handrail members 13 when in the tilted position is It is 100 mm or more.

  One of the pair of movable handrail members 13 is provided with a detection plate 31 that is a detection target, and the other is provided with a detection switch 32. The detection plate 31 is connected to an end portion on the front surface 2b side of one movable handrail member 13 via a cord-like body 33 which is a connecting member. The cord-like body 33 is a linear member that is easily bent. As the cord 33, for example, a wire, a rope, a chain, a belt, or the like is used. The length of the cord 33 is such that the detection plate 31 can reach the detection switch 32 when each movable handrail member 13 is in the fall position, and at least one of the movable handrail members 13 is out of the fall position. The length of the detection plate 31 does not reach the detection switch 32. In addition, as a connecting member for connecting the detection plate 31 to the movable handrail member 13, for example, a rod-like member, a plate-like member, or the like may be used instead of the cord-like body 33. When a bar-like member, a plate-like member, or the like that is difficult to bend is used as the connecting member, the connecting member is rotatably attached to the movable handrail member 13.

  Here, FIG. 5 is a perspective view showing the detection plate 31 and the detection switch 32 of FIG. The detection switch 32 is provided with an insertion hole 34 into which the detection plate 31 can be inserted. In a state where each movable handrail member 13 is in the collapsed position, the detection plate 31 can be inserted into the insertion hole 34 of the detection switch 32. The detection plate 31 is held by the detection switch 32 by being inserted into the insertion hole 34.

  In a state where each movable handrail member 13 is in the tilted position and the detection plate 31 is inserted into the insertion hole 34 of the detection switch 32, as shown in FIG. It is stretched in a space between the handrail member 13 and the other movable handrail member 13. As a result, the cord 33 prevents the worker from passing through the space between the one movable handrail member 13 and the other movable handrail member 13, and the worker moves from the landing 4 to the upper surface 2 a of the car 2. The boarding is prevented more reliably by the cord 33.

  The detection switch 32 detects the detection plate 31 when the detection plate 31 is inserted into the insertion hole 34 and outputs a detection signal to the control device. When the detection plate 31 is removed from the insertion hole 34, the detection switch 31 detects the detection plate 31. 31 is no longer detected and the output of the detection signal is stopped. The control device controls the operation of the elevator based on information from the detection switch 32. Service operation in the normal operation mode is permitted by the control device when the control device receives a detection signal from the detection switch 32. When output of the detection signal from the detection switch 32 to the control device stops, service operation becomes impossible and operation by operating the operation unit on the car during maintenance in the maintenance operation mode becomes possible.

  Here, FIG. 6 is a schematic diagram showing a state in which the detection plate 31 of FIG. FIG. 7 is a schematic diagram showing a state where the detection plate 31 of FIG. 6 is inserted into the insertion hole 34 of the detection switch 32. The detection switch 32 has two terminals 32 a and 32 b exposed in the insertion hole 34. The two terminals 32a and 32b are exposed in the insertion hole 34 at positions separated from each other.

  When the detection plate 31 is inserted into the insertion hole 34, the detection plate 31 contacts the two terminals 32 a and 32 b exposed in the insertion hole 34, and the two terminals 32 a and 32 b are connected to the detection plate 31. Is electrically shorted through. The detection switch 32 detects the detection plate 31 when the two terminals 32 a and 32 b are short-circuited by the detection plate 31. That is, in a state where each movable handrail member 13 is in the tilted position, the detection switch 32 can detect the detection plate 31 by inserting the detection plate 31 into the insertion hole 34.

  The detection plate 31 is detachably attached to the fixed handrail member 12 of the one side handrail 7 to which the detection plate 31 is connected. As shown in FIG. 4, the detection plate 31 is attached to the fixed handrail member 12 when the movable handrail member 13 of the one side handrail 7 is in the standing position.

  FIG. 8 is an enlarged view showing a state in which the detection plate 31 of FIG. 7 is attached to the fixed handrail member 12 of one side handrail 7. The fixed handrail member 12 of one side handrail 7 is provided with a butterfly bolt 35 that is an attachment for attaching the detection plate 31 to the fixed handrail member 12. The detection plate 31 is provided with a notch 36 into which the bolt portion of the butterfly bolt 35 can be inserted. The detection plate 31 is attached to the fixed handrail member 12 by tightening the butterfly bolt 35 with the bolt portion of the butterfly bolt 35 inserted into the notch 36. The detection plate 31 attached to the fixed handrail member 12 of the one side handrail 7 is detached from the fixed handrail member 12 by loosening the butterfly bolt 35.

  Next, an elevator maintenance / inspection procedure will be described. The service operation of the elevator is performed in the normal operation mode. When the elevator is operated in the normal operation mode, the car handrail device 6 is in a folded state, and the detection plate 31 is inserted into the insertion hole 34 of the detection switch 32.

  When an operator performs maintenance and inspection work on the upper surface 2a of the car 2, for example, the car is operated so that the upper surface 2a of the car 2 matches the height of the floor of the hall 4 by operating the operation panel of the hall 4 on the top floor. After stopping 2, open the hall entrance 5. At this time, each movable handrail member 13 of each of the side handrails 7 and 8 is disposed at the intermediate portion in the height direction of the ceiling entry port, and the cord-like body 33 is connected between each movable handrail member 13. The movable handrail member 13 and the cord-like body 33 are in the way so that the worker cannot get on the upper surface 2 a of the car 2 from the landing 4.

  Thereafter, the operator removes the detection plate 31 from the detection switch 32 and lifts the movable handrail members 13 of the side handrails 7 and 8 from the fall position to the standing position by work from the landing 4 on the top floor. When the detection plate 31 is removed from the detection switch 32, the output of the detection signal from the detection switch 32 to the control device stops. As a result, service operation becomes impossible, and operation by operating the operation unit on the car during maintenance in the maintenance operation mode becomes possible. Thereafter, the detection plate 31 is fastened to the fixed handrail member 12 of one side handrail 7 with the butterfly bolt 35.

  Thereafter, the operator gets into the upper surface 2a of the car 2 from the landing 4 through the landing entrance 5 and the ceiling entrance, and lifts the movable handrail member 22 of the rear handrail 9 from the fall position to the standing position. As a result, the state of the car handrail device 6 becomes the assembled state.

  Thereafter, the operator closes the open hall entrance 5 and then operates the operation unit on the car for maintenance to move the car 2 at a low speed. Thereby, the maintenance inspection work with respect to the apparatus in the hoistway 1 is attained.

  When the worker on the upper surface 2a of the car 2 finishes the maintenance and inspection work on the equipment in the hoistway 1, the car 2 is moved downward at a low speed while operating the operation unit on the car at the time of maintenance. The car 2 is stopped so that 2a matches the floor height of the hall 4 on the top floor, for example. Thereafter, the movable handrail member 22 of the rear handrail 9 is displaced from the standing position to the fall position, and then the landing doorway 5 on the uppermost floor is opened, and the transfer is made from the upper surface 2a of the car 2 to the landing 4.

  Thereafter, the operator displaces each movable handrail member 13 from the landing 4 to the fall position from the standing position. Thereby, the state of the car upper handrail device 6 becomes the folded state. Thereafter, the detection plate 31 removed from the fixed handrail member 12 of one side handrail 7 is inserted into the insertion hole 34 of the detection switch 32. As a result, the cord-like body 33 is in a state where it extends between one movable handrail member 13 and the other movable handrail member 13. Thereafter, the elevator maintenance inspection work is completed by closing the hall entrance 5.

  In such an elevator apparatus, the movable handrail members 13 when in the fall position are arranged in the height direction intermediate portion of the ceiling entry port in a state of facing each other in the width direction of the ceiling entry port. If the movable handrail members 13 are not displaced to the standing position, they cannot get on the upper surface 2a of the car 2 from the landing 4, and the operator can get on the car 2 before raising the side handrails 7 and 8. Prevention can be achieved. Further, in the state where each of the movable handrail members 13 is in the collapsed position, the detection switch 32 can detect the detection plate 31. Therefore, unless the detection of the detection plate 31 by the detection switch 32 is stopped, It is possible to prevent an operator from getting on the upper surface 2a of the car 2. As a result, it is possible to more reliably prevent a normal service operation from being mistakenly performed during maintenance and inspection, and it is possible to more reliably perform an operation by operating the operation unit on the car during maintenance in the maintenance operation mode. .

  Further, since the detection plate 31 is connected to the movable handrail member 13 of the one side rail 7 via the cord-like body 33, not only the movable handrail members 13 when in the fall position but also the cord-like body. 33 can also prevent the worker from getting on the car 2, and can more reliably prevent the operator from getting on the car 2 before raising the side handrails 7 and 8.

  Moreover, since the height from the upper surface 2a of the cage | basket | car 2 to the upper end part of the fixed handrail member 12 is a height in the range of 400 mm-700 mm, the height of the position of the movable handrail member 13 when it exists in a fall position is set. The height of the position where it is difficult for the operator to get over the movable handrail member 13 can be obtained. Accordingly, it is possible to further reliably prevent the worker from getting on the car 2 before raising the side handrails 7 and 8.

  In the above example, the detection plate 31 is attachable to and detachable from the fixed handrail member 12 of one side handrail 7, but is not limited to this, for example, the movable handrail member 13 of one side handrail 7 or The detection plate 31 may be detachable from the car 2 itself.

Embodiment 2. FIG.
FIG. 9 is a top view showing an elevator apparatus according to Embodiment 2 of the present invention. FIG. 10 is a front view showing the upper part of the car 2 of FIG. Further, FIG. 11 is a top view showing an upper portion of the car 2 when the state of the car handrail device 6 of FIG. 9 is an assembled state. FIG. 12 is a front view showing the upper part of the car 2 of FIG. At one end of the side handrail 7 on the front 2b side of the movable handrail member 13, a cord-like body recovery device 41 is provided. The cord recovery apparatus 41 has a winding shaft that winds the cord 33. The detection plate 31 and the cord-like body 33 are accommodated in the cord-like body recovery device 41 when the cord-like body 33 is wound around the winding shaft. The length of the cord 33 fed out from the cord collection device 41 is such that the cord 33 is continuously applied to each movable handrail member 13 when each movable handrail member 13 is in the collapsed position. It has become.

  As shown in FIG. 9, a plurality of protrusions 42 are fixed to the horizontal angle members located at the respective rotating end portions, that is, the upper end portions of the respective movable handrail members 13. The protrusions 42 are arranged at intervals from each other in the longitudinal direction of the lateral angle member of the movable handrail member 13, that is, in the depth direction of the car 2. Each projection 42 is formed with a through-hole through which the cord-like body 33 and the detection plate 31 can pass.

  In a state where the detection plate 31 is inserted into the insertion hole 34 and the detection switch 32 detects the detection plate 31, the cord 33 is sequentially passed through the through holes of the protrusions 42, and It is hung on each lateral angle member of the other movable handrail member 13. Further, in a state where the detection plate 31 is inserted into the insertion hole 34 and the detection switch 32 detects the detection plate 31, the position on the movable handrail member 13 is shifted in the depth direction of the car 2, and The movable handrail members 13 are alternately and continuously hung on the respective lateral angle members. Other configurations are the same as those in the first embodiment.

  As for the maintenance and inspection work of the elevator, the work for lifting the movable handrail members 13 of the side handrails 7 and 8 from the fall position to the standing position and the insertion of the cord 33 into the insertion hole 34 of the detection switch 32 are performed. Except for work, it is the same as in the first embodiment.

  When lifting the movable handrail member 13 of each of the side handrails 7 and 8 from the fall position to the standing position, the operator removes the detection plate 31 from the detection switch 32 by work from the landing 4, and then retrieves the cords. While winding the cord 33 around the winding shaft by the device 41, the cord 33 is sequentially removed from the one and the other movable handrail members 13, and the cord 33 and the detection plate 31 are attached to the cord collecting device 41. Accommodate. Thereafter, the movable handrail members 13 of the side handrails 7 and 8 are lifted from the fall position to the standing position.

  Further, when the cord 33 is inserted into the insertion hole 34 of the detection switch 32, after the detection plate 31 and the cord 33 are pulled out from the cord collection device 41, the detection plate 31 is inserted into the through hole of each protrusion 42. Then, while passing the cord-like body 33 sequentially, the cord-like bodies 33 are alternately and continuously hung on the one and the other movable handrail members 13, and then the detection plate 31 is inserted into the insertion hole 34 of the detection switch 32.

  In such an elevator apparatus, the cable 33 when the detection switch 32 detects the detection plate 31 shifts the position on the movable handrail member 13 in the depth direction of the car 2 while moving the one and the other movable. Since it is continuously and alternately hung on the handrail member 13, the range of the cord-like body 33 stretched between the movable handrail members 13 can be widened, and the operator can set up the side handrails 7 and 8 before standing up. It is possible to more reliably prevent the car 2 from getting on.

  In addition, each movable handrail member 13 is provided with a plurality of protrusions 42, and each protrusion 42 is provided with a through hole through which the cable-like body 33 and the detection plate 31 can pass. The position hung on 13 can be prevented from shifting.

  In the above example, the plurality of protrusions 42 provided with through holes through which the cord-like body 33 is passed are provided on the movable handrail member 13, but the portion of the movable handrail member 13 on which the cord-like body 33 is hooked is provided. You may provide a hollow. Even if it does in this way, it can make it difficult to slip the cord-like body 33 because the cord-like body 33 concerning the movable handrail member 13 fits into a hollow. Further, the plurality of protrusions 42 may not be provided. Even in this way, the cord-like bodies 33 can be alternately and continuously hung on the one and the other movable handrail members 13.

  In each of the above embodiments, the detection switch 32 has two terminals 32a and 32b, and the two terminals 32a and 32b are short-circuited via the detection plate 31, whereby the detection switch 32 is detected by the detection plate 31. However, the detection switch 32 further includes a movable contact that contacts or separates from the two terminals 32a and 32b, and the detection plate 31 is inserted into the insertion hole 34. The detection plate 31 may be brought into contact with the movable contact, and the movable contact may be pushed by the detection plate 31 in a direction in which the detection plate 31 comes into contact with the two terminals 32a and 32b. In this case, the detection switch 32 detects the detection plate 31 when the two terminals 32a and 32b are short-circuited via the movable contact.

  Moreover, in each said embodiment, although the board 31 for a detection is used as a to-be-detected body which the detection switch 32 detects, the shape of a to-be-detected body is not limited to this. For example, the shape of the detected object may be a rod shape.

  Moreover, in each said embodiment, although the distance between each movable handrail member 13 in the fall position is 100 mm or more, the distance between each movable handrail member 13 in the fall position is more than 100 mm. The distance may be a short distance, or the movable handrail members 13 may be in contact with each other when in the fall position. In this way, for example, the detection plate 31 is fixed to one movable handrail member 13 and the detection switch 32 is fixed to the other movable handrail member 13 so that each movable handrail member 13 is moved from the standing position to the fall position. By being displaced, the detection plate 31 can be automatically inserted into the insertion hole 34 of the detection switch 32. Thereby, the cord-like body 33 can be eliminated. In this case, the detection switch 32 may be a contact type switch that detects the detection plate 31 by contact, or may be a proximity switch that detects the detection plate 31 in a non-contact manner.

  Further, the cord-like body recovery device 41 of the second embodiment may be attached to the movable handrail member 13 of the one side handrail 7 of the first embodiment.
