Description

  One embodiment relates to an elevator car.

  The elevator doors are equipped with doors on the landing side and the car side. When the car arrives at each floor, the engaging device provided in the car side door engages with the engaging portion such as an interlock roller provided in the landing side door, and the car side door is driven by the power provided in the car side door. And the landing door opens at the same time.

  By the way, in an elevator with a long up-and-down stroke, a temperature difference and a pressure difference are generated up and down in and out of the hoistway or in the hoistway. Due to temperature differences and atmospheric pressure differences, an airflow that flows from the hoistway side toward the landing may be generated on the upper floor.

  2. Description of the Related Art Conventionally, an elevator door device that reduces an air flow passing between a car door and a safety shoe is known (see, for example, Patent Document 1). There has also been proposed an elevator apparatus that includes a guide guided by a sill attached by a cover on the door opening end side of the car door, and the cover closes between the car door and the doorway column when the door is closed (Patent Document). 2).

JP 2007-308287 A Japanese Patent No. 3379428

  However, in an elevator with a long up / down stroke, when the car door is opened on the upper floor, the car door is pushed in the direction from the door pocket to the door stop due to the airflow from the inside of the hoistway to the landing side, and the car door is fully opened. May occur. There is a gap between the door end side surface of the car door panel and the wall of the hoistway, and the airflow flows to the landing through this gap. There is a gap between the panel surface of the car door panel on the landing side and the panel surface of the landing door panel, and another airflow flows to the landing through this gap. When the momentum of the airflow increases and the airflow increases, the car door cannot be fully opened.

  In order to improve the smoke shielding performance, the elevator has a structure that increases the sealing degree. The car door and the landing door are required to eliminate the gap and to close the gap. Based on the temperature difference between the inside and outside of the hoistway, the pressure difference of the air is caused by the difference in the position in the hoistway. When the atmospheric pressure is different between the inside and outside of the hoistway, wind is generated, and when the atmospheric pressure difference is large, the wind speed is increased. On the upper floor of a high-rise building, the air pressure in the hoistway is greater than the air pressure at the landing. The momentum of the wind flowing from the hoistway to the landing increases. When the ascending / descending stroke is long, the sealing degree is large, and the wind is strong outdoors, the momentum of the wind increases and a draft occurs. It may interfere with the fully opening operation of the car door.

  In order to solve such a problem, according to one embodiment, a car frame that moves up and down in a hoistway that opens to a landing, an arm member that is fixed to the car frame and extends in the front-rear direction, and is connected to the arm member. A vertical member extending in the vertical direction, a car room having a doorway located on the side of the vertical member and supported by the car frame, a door panel for opening and closing the doorway of the car room, and when the door panel is fully opened A wind regulation plate provided on the vertical member, facing the end surface of the door panel of the door panel, and the wind regulation plate from the hoistway when the cab is landed and opened. There is provided an elevator car characterized in that the wind toward the landing is cut off.

  Hereinafter, an elevator car according to an embodiment will be described with reference to the drawings. In the drawings, the same portions are denoted by the same reference numerals, and redundant description is omitted. In the following description, the length direction of the hoistway may be referred to as the vertical direction, the depth direction of the hoistway may be referred to as the front-rear direction, and the width direction of the hoistway may be referred to as the left-right direction.

(First embodiment)
The elevator car according to the first embodiment is a car having a central double door system. This elevator car has a wind regulation structure that blocks wind flowing to the landing through a gap formed in the car door panel. The gap refers to a gap between the door panel surfaces, a gap between the door panel surface and the wall surface, and a gap between the door panel surface and the car support member.

  FIG. 1 is a perspective view of an elevator car. This figure shows a perspective view of the car door device and the air conditioning plate removed. The car 1 includes a car frame 2, a car room 3 disposed in the car frame 2, and a frame body 4.

  The car frame 2 includes, for example, an upper beam 2a, a lower beam 2b, and left and right standing frames 2c and 2d, and a floor receiving frame 5 is fixed to the car frame 2. The frame 4 is installed on the floor board 6. The frame body 4 includes a plurality of arm members 7 that extend in the horizontal direction above the standing frames 2c and 2d, and car support members 8a and 8b (vertical members) that are connected to ends of the arm members 7 and extend in the vertical direction. ) Etc. The car support members 8 a and 8 b are columnar members connected to the lower beam 2 b and support the arm member 7. The car support members 8a and 8b are positioned in front of the car room 3 in parallel to the left and right. The distance between the car support members 8a and 8b is approximately the same as the outer dimension of the rectangular floor board 6.

  The floor receiving frame 5, the floor plate 6, the arm member 7, the car support members 8a and 8b, and the left side plate 9 and the right side plate 10 in front of the car room form a car room 3. A car sill 11 is provided on one end of the floor board 6. The space above the car sill 11 forms an entrance 12 through which passengers get on and off. The entrance / exit 12 includes a pair of entrance columns (entrance / entrance columns) 13 and 14 extending vertically, and an upper frame member 15 passed between upper ends of the entrance columns 13 and 14.

  FIG. 2 is a horizontal sectional view of the door system when the car 1 is cut along the line AA ′ of FIG. 1, and shows a plan structure of the door system when the door is opened. The above described symbols represent the same elements. The upper part of the figure represents the depth direction of the cab 3 and the lower part represents the landing 33 side. The door system 16 includes double-opening-type car door panels 17 and 18 (door panels) for opening and closing the doorway 12, and landing door panels 19 and 20 provided with a gap from the car door panels 17 and 18, respectively.

  The car door panel 17 has a panel surface 17 a on the depth side of the car room 3, a panel back surface 17 b on the landing 33 side, and a door-bag side end surface 17 c facing the door-bag side end portion 21. On the other hand, the car door panel 18 has a panel surface 18 a on the depth side of the car room 3, a panel back surface 18 b on the landing 33 side, and a doorcase side end face 18 c facing the doorcase side end portion 22. The door pocket refers to a space in which the car door panels 17 and 18 are stored. The plate surface of the left side wall plate 9 is inclined with respect to the panel surface 17 a of the car door panel 17. The plate surface of the right side wall plate 10 is inclined with respect to the panel surface 18 a of the car door panel 18. Safety shoes 23 and 24 may be fixed to the panel back surface 17b and the panel back surface 18b, respectively. The safety shoes 23 and 24 are for detecting obstacles by mechanical contact with obstacles such as passengers and luggage.

  In the present embodiment, the air conditioning plates 25 and 26 are attached to the car support members 8a and 8b in the vicinity of the door bag side when the car door is fully opened. For the attachment, fastening with bolts and nuts via brackets or fastener plates is used. Alternatively, for this attachment, fastening by bolts and nuts is used directly from through holes formed in the air conditioning plates 25 and 26.

  FIG. 3A is a perspective view of the air conditioning plate 26. The air conditioning plate 26 is a steel plate or a resin plate. For example, the plate material is formed to be bent by two fold lines parallel to each other in the vertical direction, and one end side portion of the plate material is folded back to the entrance / exit 12. The air conditioning plate 26 has surface portions 52, 53, 54 on the inner side facing the car door panel 18. When the car door panel 18 is fully opened, the surface portion 53 faces the door pocket side end surface 18c, and the surface portion 54 faces the panel back surface 18b. The surface portion 52 faces the panel surface 18a. These surface portions 52, 53, 54 cover the vicinity of the door-seat-side end surface 18 c and block the flow of wind from the gap portion of the car door panel 18 toward the landing 33. The air conditioning plate 26 may have a length in the vertical direction over the entire height direction of the car door panels 17 and 18.

  The air conditioning plate 25 has a shape symmetrical to the external shape of the air conditioning plate 26 and has surface portions 52, 53, and 54. Symmetry refers to mirror image symmetry. The air conditioning plate 25 has substantially the same air conditioning function as the air conditioning plate 26. By increasing the vertical lengths of the air conditioning plates 25 and 26, it is possible to increase the air volume of the target to be prevented from passing.

  The hoistway 27 of FIG. 2 has a left wall surface 28 and a right wall surface 29. The floor plate 6, the left side plate 9, and the left side wall surface 28 define a space 30. The air conditioning plate 25 prevents air from flowing from the space 30 to the entrance / exit 34 on the landing 33 side when the door is closed. The air conditioning plate 25 prevents air from flowing from the space 30 over the panel surface 17a of the car door panel 17 to the doorway 12 when the door is opened. As for the right side, the floor plate 6, the right side plate 10, and the right side wall surface 29 define a space 31. The air conditioning plate 26 prevents air from flowing from the space 31 to the entrance / exit 34 when the door is closed, and air flows from the space 31 to the entrance / exit 12 through the panel surface 18a of the car door panel 18 when the door is opened. Stop that. The air conditioners 25 and 26 block the wind passing from the hoistway 27 to the landing 33 through the door-bag side ends of the car door panels 17 and 18.

  Furthermore, the door system 16 includes a car door guide mechanism such as a door rail (not shown) and an engagement device. The car door panels 17 and 18 are suspended from the door rail by rollers and hangers, and are guided in the grooves of the car sill 11. The landing door panels 19 and 20 receive the opening / closing force from the car door panels 17 and 18 through the engagement devices. When the door is opened, the car door panels 17 and 18 move toward the door end portions 21 and 22 on the car sill 11, respectively. When the door is opened, the panel surface 17a faces the entrance pillar 13 and the car support member 8a, and the panel surface 18a faces the entrance pillar 14 and the car support member 8b.

  The inlet column 13 has a column surface portion 35 and a folded portion 36 continuous with the column surface portion 35. The vertical length of the column surface portion 35 is approximately the same as the height of the car door panel 17. The column surface portion 35 defines the left side edge portion of the entrance 12. The vertical length of the folded portion 36 is also approximately the same as the height of the car door panel 17. The folded portion 36 protrudes toward the door pocket side end portion 21 from a bent portion where the folded portion 36 is continuous with the column surface portion 35. The entrance column 14 also has a column surface portion 37 and a folded portion 38 that is continuous with the column surface portion 37. The column surface portion 37 extending in the vertical direction defines the right side edge portion of the entrance 12. The folded portion 38 protrudes toward the door pocket side end portion 22.

  Further, the car 1 ascends and descends through a hoistway 27 defined by the building housing 32. The hoistway 27 opens to the landing 33 side, and the entrance 34 communicates the hoistway 27 and the landing 33. Vertical frames 39 and 40 are provided on the left and right of the entrance 34. The vertical frames 39 and 40 and the upper frame (not shown) constitute a landing three-way frame. The landing door panels 19 and 20 move along the grooves in the landing sill 55 by the door rail provided on the upper frame. The landing door panels 19 and 20 open and close the entrance 34. When the car 1 is landed, the engaging device grips one of the projections on the panel back surface 19b and the panel back surface 20b. The opening / closing force is transmitted from the car 1 side to the landing door panels 19 and 20. The landing door panels 19 and 20 perform an opening operation and a closing operation. The car door panels 17 and 18 perform opening and closing operations while maintaining a slight gap with respect to the entrance pillars 13 and 14, respectively.

  The door system 16 having the car 1 configured as described above opens the car door panels 17 and 18. FIG. 4 is a diagram showing a planar structure of the door system 16 when the door is opened. This figure shows a horizontal cross section when the car 1 is cut along the line AA 'in FIG. The above described symbols represent the same elements.

  When fully opened, the panel surface 17a faces each of the car support member 8a and the folded portion 36 with a gap. The air conditioning plate 25 arranged in the gap blocks the airflow from the hoistway 27 and the space 30 to the landing 33 and the entrance 12. Similarly, the panel surface 18a faces each of the car support member 8b and the folded portion 38 with a gap therebetween. The air conditioning plate 26 disposed in the gap blocks the airflow from the hoistway 27 and the space 31 to the landing 33 and the entrance 12. Each airflow is bounced back by the air conditioning plates 25 and 26.

  In the hoistway 27 where the traveling distance of the car frame 2 is long, a difference in air temperature and a difference in atmospheric pressure occur inside and outside the hoistway 27. In the hoistway 27, a difference in temperature and a difference in atmospheric pressure are generated up and down. Due to a temperature difference or a pressure difference, an air flow may occur in the direction from the hoistway 27 toward the landing 33 on the upper floor of a high-rise building. When the air pressure in the hoistway 27 becomes larger than the air pressure in the landing 33, the wind speed and momentum of the wind flowing from the hoistway 27 to the landing 33 increases. In the present embodiment, the air conditioning plates 25 and 26 prevent the air from the spaces 30 and 31 from flowing to the landing 33. Opening / closing abnormality of the car door panels 17 and 18 due to the draft does not occur. The airflow flowing on the rear wall surface of the hoistway 27 and the airflow flowing on both sides of the car 1 are prevented from flowing from the hoistway 27 to the landing 33 by the air conditioning plates 25 and 26. The full opening operation of the car door panels 17 and 18 is normally maintained by the air conditioning structure provided in the door system 16. Even if a wind flow occurs from the hoistway 27 toward the landing 33 side top floor, the car door panels 17 and 18 normally open and close.

  FIG. 5 shows a horizontal cross section of a door system in which the air conditioning plates 25 and 26 are not provided as a comparative example. FIG. 5 is a diagram showing a planar structure of a door system according to a conventional example. The above described symbols represent the same elements. In the door system 100, a plurality of airflows flowing from the hoistway 27 side to the landing 33 side are generated. On the left side, airflow flows through the gap between the car support member 8 a and the car door panel 17. Furthermore, the airflow flows through a gap between the column surface portion 35 and the car door panel 17, a gap between the door pocket side end face 17 c and the left wall surface 28, a gap between the car door panel 17 and the landing door panel 19. On the right side, there is a gap between the car support member 8b and the car door panel 18, a gap between the column surface portion 37 and the car door panel 18, a gap between the door bag side end face 18c and the right wall surface 29, or between the car door panel 18 and the landing door panel 20. It flows through gaps.

  The airflow w flows out to the landing 33 side through these gaps. At this time, the presence of the air flow w causes the door closing force to act on the car door panels 17 and 18 in such a direction that the car door panels 17 and 18 are pushed from the door pockets into the door stops. In the conventional example, since each door closing force is applied to the car door panels 17 and 18, a situation in which the door opening operation is hindered may occur.

  On the other hand, in the door system 16, the air conditioning plate 25 covers the space 30 in a planar shape in the vertical direction from the folded portion 36 of the entrance pillar 13 to the surface portion of the car support member 8 a. The air conditioning plate 25 covers the door end surface 17c of the car door panel 17 in a concave shape from three sides. The air conditioning plate 26 also covers the space 31 in the vertical direction from the entrance column 14 to the surface portion of the car support member 8b, and covers the door-side end surface 18c in a concave shape. These air conditioning plates 25 and 26 block the air flow w of FIG. A plurality of airflows w can be blocked. Each airflow is bounced back by airflow control plates 25 and 26 that are fixedly installed. The air flow w is prevented from exerting a force on the panel surface 17 a, the panel back surface 17 b, and the door-bag side end surface 17 c of the car door panel 17. The airflow w is prevented from exerting a force on the panel surface 18 a, the panel back surface 18 b, and the door pocket side surface 18 c of the car door panel 18. In this way, it is possible to smoothly open the car door. The door system 16 can realize a smooth door opening / closing operation.

  It is also possible to take measures to increase the door opening force by increasing the rotational torque of the door opening / closing motor of the door device as compared with the conventional example of FIG. However, increasing the torque value of the motor according to the magnitude of the door opening force on the upper floor makes the door opening force on the lower floor larger or excessive than the minimum required door opening force. The operating environment of the elevator may change due to seasonal changes. The operating environment refers to the outdoor average temperature and the temperature in the hoistway 27. When the operating environment changes, it is necessary to readjust the door opening force of the door device. When the door opening force is increased, there is no risk that a hand or the like is drawn into the gap between the car door panels 17 and 18 and the vertical frames 39 and 40 and the entrance pillars 13 and 14 when the car door is opened. Increasing the motor torque value increases power consumption.

  The door system 16 can block the flow of wind. In an elevator with a long up / down stroke, such as installed in a high-rise building with a long travel distance, even if an air flow from the hoistway 27 side to the landing 33 side occurs on the upper floor, it is ensured without adjusting the torque of the motor. The car door and the landing door can be fully opened.

(Modification of the first embodiment)
The door system may use a single door.

  FIG. 6 is a diagram showing a planar structure of an elevator car door system according to a modification of the first embodiment, and shows a horizontal section when the door is closed. FIG. 7 is a diagram showing a planar structure of the door system, and shows a horizontal section when the door is opened. The above-described symbols represent the same elements as those described above. Elements having the same reference numerals represent the same elements.

  The door system 47 of the car 1A is a single-open type. A car sill 41 is formed below the doorway 12. The folded portion 36 has a folded portion 36a. An entrance post 42 is erected on the right side. The side wall plate 43 has a plate surface parallel to the right side wall surface 29. The side wall plate 43 is continuous with the inlet column 42. The inlet column 42 has a column surface portion 44 and a bent portion 45. Opposite to the car sill 41, a landing sill 46 is provided on the landing 33 side.

  The door system 47 includes single-open car door panels 48 and 49 that open and close the doorway 12, respectively, and landing door panels 50 and 51 that are provided with a space from the car door panels 48 and 49, respectively. The car door panels 48 and 49 are arranged in front and rear steps so as to open and close.

  The car 1A has an air conditioning plate 25 on the left side. The air conditioning plate 25 is attached to the car 1A in the vicinity of the door pocket side in the fully open position of the car door panels 48 and 49. The air conditioning plate 25 has a length in the up and down direction over the entire vertical section of the car door panels 48 and 49.

  The car 1A having such a configuration opens the car door panels 48 and 49. As shown in FIG. 7, the car door panels 48 and 49 are accommodated and disposed so as to overlap with each other in the door pocket side end portion 21. Further, when the door closing operation is started from the door open state, the car door panels 48 and 49 move toward the entrance column 42 and the car door panels 48 and 49 and the landing door panels 50 and 51 are closed. One car door panel 48 moves at a low speed. The speed of the other car door panel 49 is approximately twice the speed of the car door panel 48. As a result, the car door panels 48 and 49 close the doorway 12 when the door is closed. When the door is opened from the door-closed state, the car door panel 48 moves at a low speed toward the door-bag side end 21, and the car door panel 49 also moves toward the door-bag side end 21 at a higher speed than the speed of the car door panel 48. It moves and is stored in the door pocket.

  The landing door panels 50 and 51 are opened and closed when the opening and closing force is transmitted from the car door panels 48 and 49. The landing door panel 50 is a low speed door. The landing door panel 51 is a high-speed door. The landing door panel 51 reciprocates in parallel with the landing door panel 50 and at a speed approximately twice the speed of the landing door panel 50.

  The air conditioning plate 25 covers the space 30 in a plane shape in the vertical direction from the folded portion 36 of the inlet column 13 to the surface portion of the car support member 8a. The air conditioning plate 25 covers the end surfaces of the car door panels 48 and 49 on the door pocket side. Wind flow can be blocked by the air conditioning plate 25. Each airflow is bounced back by the air conditioning plate 25.

  The air conditioning plate 25 prevents airflow that passes through the gaps between the car support member 8 a and the car door panel 48, between the column surface portion 35 and the car door panel 48, and between the door bag side end face and the left wall surface 28 of the car door panel 48. Further, the air conditioning plate 25 prevents airflow passing through the gaps between the car door panel 48 and the car door panel 49 and between the car door panel 49 and the landing door panel 51.

  The air conditioning plate 25 can block a plurality of airflows passing through these gaps. Airflow from the hoistway 27 toward the landing 33 is blocked. It is possible to smoothly open the car door.

(Second Embodiment)
The width in the frontage direction of the air conditioning plates 25 and 26 may be shortened.

  FIG. 8 is a partial cross-sectional view showing a planar structure of an elevator car door system according to the second embodiment. The above described symbols represent the same elements. The door system 16A is provided in an elevator car that is substantially the same as the example of FIG. The door system 16A blocks the airflow passing through the gaps formed in the car door panels 17 and 18 by the air conditioning plates 25A and 26A. Among the structures shown in FIG. 8, the structures common to the first embodiment are the same as those, and redundant description is omitted.

  FIG. 9 is a perspective view of the air conditioning plate 26A. The air conditioning plate 26A is a steel plate or a resin plate, and is formed by bending a steel plate or a resin plate. The air conditioning plate 26 </ b> A has a vertical length similar to the height of the car door panels 17 and 18. The air conditioning plate 26A prevents air from flowing from the hoistway 27 to the landing 33 when the door is closed. The air conditioning plate 26 </ b> A prevents air from flowing from the hoistway 27 to the doorway 12 through the panel surface 18 a of the car door panel 18 when the door is opened. The air conditioning plate 25A also has a symmetrical shape with the air conditioning plate 26A, and is substantially the same as the air conditioning plate 25A.

  Since the door system 16A has a structure in which the air conditioning plates 25A and 26A are attached to the support members 8a and 8b by shortening the width in the frontage direction, the weight of the air conditioning plates 25A and 26A can be reduced.

  As a specific example, the height size of the car door panels 17 and 18 is about 2 meters. The width size of the doorway 12 is at least about 800 millimeters. The width size of the car door panels 17 and 18 is about 400 mm, which is half of the width. By setting the width of the air conditioning plates 25A and 26A to several tens of centimeters, the door system can be reduced in weight even if the air conditioning plates 25A and 26A are made of steel or synthetic resin.

(Third embodiment)
In order to reduce the weight of the door systems 16, 47 and 16A, a through hole may be provided in the air conditioning plate. The door system of an elevator car according to the third embodiment is reduced in weight while maintaining the function of blocking the flow of wind using punching metal. The planar structure of the door system is substantially the same as the example of FIG. 2 or FIG. This door system is also provided in the elevator car which is substantially the same as the example of FIG. Among the structures used by the door system, the same structures as those of the first embodiment are the same.

  FIG. 10A is a perspective view of the air conditioning plate of the door system. The air conditioning plate 25B is a punching metal and has a large number of through holes 59 having a small diameter. Alternatively, as shown in FIG. 10B, the conditioned plate 25C may use expanded metal. The air conditioning plate 25C has a number of meshes 60.

  A pair of right and left air conditioning plates 25B having such a configuration is provided, and these air conditioning plates 25B block airflow from the hoistway 27 toward the landing 33. Each airflow is bounced back by a pair of air conditioning plates 25B. The same applies to an example in which a door system is provided with a pair of air conditioning plates 25C.

  Thereby, the weight of the air conditioning plates 25B and 25C can be reduced.

(Fourth embodiment)
In some door systems, a light sensor such as a multi-optical axis sensor or a phototube is provided to detect an object when the door is closed. A pair of multi-optical axis sensors are respectively fixed to the car support members 8a and 8b via plate pieces. Two multi-optical axis sensors are attached to one end side of each plate piece so that each detection direction faces the center of the entrance / exit 12, and the other end side of these plate pieces is fixed to the car support members 8a and 8b, respectively. The

  In the elevator car door system according to the fourth embodiment, in the first to third embodiments described above, an optical sensor is provided together with the air conditioning plate. As an example, two multi-optical axis sensors are attached to the respective surface portions 53 inside the two air conditioning plates. This door system has a structure in which two air conditioning plates 25 and 26 each having an opening are provided so that an operator can look into and inspect two multi-optical axis sensors from these openings. The door system is also provided in an elevator car having substantially the same shape as the example of FIG. This door system has a controller in the car room 3 that receives the output of the multi-optical axis sensor and stops the opening / closing operation of the car door panels 25, 26 and the like. The other structures of the door system are the same as those in the first embodiment.

  FIG. 11 is a perspective view of the air conditioning plate. The above described symbols represent the same elements. The air conditioning plate 56 has an inspection window 57 (window) in the surface portion 52. The multi-optical axis sensor 58 (optical sensor) is directly provided on the surface portion 53. Alternatively, the multi-optical axis sensor 58 is attached so as to extend from the car support member 8b via a plate piece or an arm member (not shown). The multi-optical axis sensor 58 has a light emitting element and a light receiving element. The multi-optical axis sensor 58 irradiates the entrance / exit 12 with a large number of light beams, detects that the light beams are shielded, and detects the presence of an object. The control unit constantly monitors the sensor output, and performs the door opening operation when the output of the multi-optical axis sensor 58 shows an abnormal value.

  The elevator car of the door system having such a configuration is installed in a hospital, for example. Wheelchair users use elevators. The direction of the wheelchair is changed after the wheelchair user's baggage is placed at the entrance 12. The multi-optical axis sensor 58 detects this load. The multi-optical axis sensor 58 detects that an object is present near the door stop of the car door panels 17 and 18. The output of the multi-optical axis sensor 58 interrupts the processing of the control unit. The control unit extends the door open state. Or a control part performs the control which stops the car door panels 17 and 18 in door closing, and opens these car door panels 17 and 18. Accidents can be prevented.

  Further, during maintenance, the operator performs an inspection on the left side plate 9 and the right side plate 10 side of the cab 3. The operator checks the direction of sensitivity of the air conditioning plates 25 and 26 from the inspection window 57 and that there is no dirt. The same applies to the air conditioning plates 25A to 25C and 26A to 26C.

  In summary, in order to prevent a hand or the like from being caught in the entrance / exit portion of the elevator when the door is opened, a sensor such as a multi-optical axis sensor 58 or a photoelectric tube may be attached to the car support members 8a and 8b. At that time, if the door pocket side end portions 21 and 22 are covered by the air conditioning plate 25 and the like, it is difficult to adjust and maintain the multi-optical axis sensor 58 on the surface portion 53.

  In the present embodiment, by providing the inspection window 57 in the air conditioning plate 56, it is possible to inspect the multi-optical axis sensor 58 or a sensor such as a photoelectric tube without removing the air conditioning plate 56. The worker can save time and effort to remove the air conditioning plate 25 and the like at the time of installing the door system and checking the car, thereby improving the efficiency of the visual inspection work.
