Moreover, although description is given in the following order, this invention is not necessarily limited to the following forms.

<Embodiment example>
First, the configuration of an elevator according to an embodiment of the present invention (hereinafter referred to as “this example”) will be described with reference to FIG.
FIG. 1 is a schematic configuration diagram showing a configuration example of the elevator of this example.

  As shown in FIG. 1, the elevator 1 of this example moves up and down in a hoistway 110 formed in a building structure 200. The elevator 1 includes a car 120 on which people and luggage are placed, a rope 130, a counterweight 140, and a hoisting machine 100. The hoistway 110 is formed in a building structure, and a machine room 160 is provided on the top thereof.

  The hoisting machine 100 is disposed in the machine room 160 and raises and lowers the car 120 by winding a rope 130. Further, in the vicinity of the hoisting machine 100, a warping wheel 150 on which the rope 130 is mounted is provided.

  The counterweight 140 is set to approximately the same mass as that of the car 120 when not loaded. Therefore, the tension ratio between the ropes 130 on the side of the car 120 and the counterweight 140 is 1 when there is no object or person loaded in the car 120. As a result, the output of the hoisting machine 100 when there is no load can be kept low.

  The car 120 is formed in a hollow, substantially rectangular parallelepiped shape. The car 120 is connected to the counterweight 140 via the rope 130 and moves up and down in the hoistway 110.

  In addition, an entrance / exit 202 through which people and objects enter / exit the car 120 is provided at a landing 201 to the car 120 on each floor of the building structure 200. A building-side door pocket 180 constituting the elevator 1 is disposed at the entrance / exit 202. A door is attached to the building side door pocket 180 so as to be openable and closable.

  A shielding member 20 for the top floor is attached to the top of the building-side door pocket 180 on the top floor. A shielding member 40 for the general floor is attached to the upper part of the building-side door pocket 180 of the general floor, which is a floor between the top floor and the bottom floor. Further, a shielding member 60 for the lowermost floor is attached to the building-side door pocket 180 on the lowermost floor.

FIG. 2 is a plan view schematically showing the elevator of this example.
As shown in FIG. 2, the elevator 1 includes a guide rail 2 that guides the car 120, a counterweight guide rail 3 that guides the counterweight 140, a control unit 4 that controls the operation of the elevator 1, And a position detector 80 provided in the car-side door pocket 121 of the car 120.

  In addition, although the example which provided the position detection part 80 in the car side door pocket 121 was demonstrated in this example, it is not limited to this. For example, the position detector 80 may be provided at the upper part of the car 120 in the up-and-down direction or at the lower part of the car sill facing the car-side door pocket 121 in the up-and-down direction.

  The position detection unit 80 is disposed on one side in the horizontal direction in the car-side door pocket 121. The position detection unit 80 includes a first detection unit 81, a second detection unit 82, and a third detection unit 83.

  3A to 3D are views showing the vicinity of the position detector 80 in an enlarged manner. FIG. 3A shows the general floor, FIG. 3B shows the top floor, and FIG. 3C shows the bottom floor. FIG. 3D shows a position moved upward or downward from a predetermined stop position on the uppermost floor or the lowermost floor.

  As shown in FIG. 3A, the first detection unit 81 is disposed on one side in the horizontal direction of the position detection unit 80, and the third detection unit 83 is disposed on the other side in the horizontal direction of the position detection unit 80. . The second detection unit 82 is disposed between the first detection unit 81 and the third detection unit 83. In addition, since the 1st detection part 81, the 2nd detection part 82, and the 3rd detection part 83 have the respectively same structure, the 1st detection part 81 is demonstrated here.

  The first detection unit 81 is an optical sensor including a light emitting unit 84 that emits light and a light receiving unit 85 that receives light from the light emitting unit 84. The light emitting part 84 and the light receiving part 85 are connected by a connecting part 86. The light emitting unit 84 and the light receiving unit 85 are opposed to each other with a gap in the horizontal direction with the connecting portion 86 interposed therebetween. The first detection unit 81 is attached to the car-side door pocket 121 with the opening formed between the light-emitting unit 84 and the light-receiving unit 85 facing the building-side door pocket 180 provided in the hoistway 110. Yes.

  The first detection unit 81 outputs a detection signal to the control unit 4 when shielding pieces 28, 48 and 68 described later are inserted between the light emitting unit 84 and the light receiving unit 85. Then, the control unit 4 stops the car 120 at which floor depending on which detection unit among the first detection unit 81, the second detection unit 82, and the third detection unit 83 in the position detection unit 80 is shielded. Detect if you did.

  In this example, the example in which the number of detection units of the position detection unit 80 is three has been described. However, the present invention is not limited to this. For example, it is sufficient that there are at least two detection units, You may provide four or more detection parts.

Here, an example of a method for identifying the stop floor of the car 120 in the position detection unit 80 of this example will be described.
As shown in FIG. 3A, when the car 120 stops on the general floor, the shielding member 40 for the general floor, which will be described later, is interposed between the light emitting unit 84 and the light receiving unit 85 of the first detection unit 81 and the third detection unit 83. The shielding piece 48 is inserted. Thereby, the control unit 4 (see FIG. 2) identifies that the car 120 is stopped on the general floor.

  As shown in FIG. 3B, when the car 120 stops on the top floor, the shielding member 20 for the top floor, which will be described later, is interposed between the light emitting unit 84 and the light receiving unit 85 of the second detection unit 82 and the third detection unit 83. The shielding piece 28 is inserted. Thereby, the control unit 4 (see FIG. 2) identifies that the car 120 is stopped on the top floor.

  Further, as shown in FIG. 3C, when the car 120 is stopped at the lowest floor, the lower floor described later is interposed between the light emitting portion 84 and the light receiving portion 85 of the first detecting portion 81 and the second detecting portion 82. The shielding piece 68 of the shielding member 60 is inserted. Thereby, the control unit 4 (see FIG. 2) identifies that the car 120 is stopped at the lowest floor.

  Here, the elevator needs to stop the car safely when the car goes too far from the top floor or the bottom floor. Therefore, in a conventional elevator, a mechanical limit switch including a cam and a push switch for detecting that the car has passed from the uppermost floor or the lowermost floor is provided separately from the position detection unit. However, in the conventional elevator, not only the number of parts is increased by the limit switch, but also a space for arranging the limit switch in the hoistway is required.

  On the other hand, the elevator 1 according to the present example detects the excessive traveling of the car 120 by the position detection unit 80. Specifically, as shown in FIG. 3D, when the car 120 goes too far from the top floor or the bottom floor, the top of the light detectors 84 and the light receivers 85 of all the detectors 81, 82, 83 are not connected to the top. The shielding pieces 28 and 68 of the shielding member 20 for the floor or the shielding member 60 for the lowest floor are inserted. Thereby, the control unit 4 (see FIG. 2) detects that the car 120 has gone too far from a predetermined stop position on the uppermost floor or the lowermost floor, and stops the car 120.

  Thus, the elevator 1 of this example can not only identify the location where the car 120 has stopped by the detection pattern of the position detector 80, but also the car 120 may have gone too far from the predetermined stop position. Can be identified. Thereby, it is not necessary to provide a limit switch separately from the position detector 80 and the shielding members 20, 40, and 60, and the number of parts of the elevator 1 can be reduced. Further, by reducing the limit switch, a space is generated in the hoistway 110, and another machine can be arranged.

  In the elevator 1 of this example, the pattern shown in FIG. 3A to FIG. 3D has been described as a method for identifying the stop floor and the overshoot state of the car 120 in the position detection unit 80, but is not limited thereto. Various settings can be made according to the number of detection units, the number of shielding pieces, and the detection pattern. For example, when the car 120 stops on the general floor, the top floor, or the bottom floor, the shielding piece may be inserted into only one of the three detection units. Further, when the car 120 goes too far from a predetermined stop position, a shielding piece may be inserted into any two of the three detection units.

Next, the general floor shielding member 40 provided on the general floor will be described with reference to FIGS.
FIG. 4 is a front view showing the entrance / exit 202 on the general floor as viewed from the hoistway side. 5 to 8 show a shielding member 40 for a general floor, FIG. 5 is an exploded perspective view, FIG. 6 is a front view, FIG. 7 is a side view, and FIG.

  As shown in FIG. 4, a building-side door pocket 180 is provided in the upper part of the entrance / exit 202. The general floor shielding member 40 is fixed to the upper portion of the building-side door pocket 180 via a fixing bolt 91. The general-level shielding member 40 is erected upward from the upper end of the building-side door pocket 180 in the ascending / descending direction.

  As shown in FIG. 5, the general floor shielding member 40 includes a fixing bracket 41, a shielding plate 42 attached to the fixing bracket 41, a fixing bolt 91, and a fixing nut 92.

  The fixing bracket 41 includes a main surface plate 44, a mounting plate 45, and two fixing plates 46. The main surface plate 44 is formed in a rectangular shape. A mounting plate 45 is bent substantially vertically and continuously at one end in the longitudinal direction of the main surface plate 44, and a fixing plate 46 is bent and continued substantially vertically at both ends in the short direction of the main surface plate 44. ing. The mounting plate 45 and the two fixing plates 46 are bent in the same direction from the end of the main surface plate 44. The two fixing plates 46 are opposed to each other with the main surface plate 44 interposed therebetween.

  The mounting plate 45 and the two fixing plates 46 are provided with through holes 47 through which the screw portions 91a of the fixing bolts 91 pass. The opening diameter of the through hole 47 is set to be larger than the diameter of the threaded portion 91 a of the fixing bolt 91, and is set to be smaller than the outer diameter of the head 91 b of the fixing bolt 91.

  As shown in FIGS. 6 and 7, the mounting plate 45 is placed on the upper end portion of the building side door pocket 180 and fixed to the upper end portion of the building side door pocket 180 via the fixing bolt 91 and the fixing nut 92. The Thereby, the fixed bracket 41 is erected from the upper end portion of the building-side door pocket 180 toward the upper side of the elevator car 120 in the up-and-down direction. At this time, as shown in FIG. 7, the ends of the two fixed plates 46 on the opposite side of the connecting portion with the main surface plate 44 are directed to the hoistway 110.

  As shown in FIG. 5, the shielding plate 42 has a U-shaped cross section in the horizontal direction. The shielding plate 42 has two shielding pieces 48 and a rectangular connecting piece 49 that connects the two shielding pieces 48. The two shielding pieces 48 are bent from both ends of the connecting piece 49 in the short direction toward the same direction substantially perpendicularly. As shown in FIG. 3A, the distance between the two shielding pieces 48 of the general shielding member 40 is determined by the third detection unit 83 from the gap between the light emitting unit 84 and the light receiving unit 85 of the first detection unit 81 in the position detection unit 80. It is set to be equal to the gap between the light emitting portion 84 and the light receiving portion 85.

  Each of the two shielding pieces 48 is provided with a fixing hole 51 into which the screw portion 91a of the fixing bolt 91 is inserted. The diameter of the fixing hole 51 is set smaller than the diameter of the through hole 47 provided in the fixing bracket 41.

  Further, the length of the connecting piece 49 in the short direction is set to be the same as or slightly shorter than the distance between the two fixing plates 46 of the fixing bracket 41. As shown in FIGS. 7 and 8, the connecting piece 49 is inserted between the two fixing plates 46 in the fixing bracket 41. In addition, the two shielding pieces 48 are arranged in contact with opposing surfaces of the two fixing plates 46, respectively. The shielding plate 42 is fixed to the fixing bracket 41 via a fixing bolt 91 and a fixing nut 92. Thereby, the fixing bracket 41 holds the shielding plate 42.

  The direction in which the two shielding pieces 48 on the shielding plate 42 extend is arranged in parallel with the raising / lowering direction of the car 120 from the fixed bracket 41. The two shielding pieces 48 protrude from the fixed bracket 41 toward the hoistway 110. 7 and 3A, when the car 120 moves to the general floor, the shielding piece 48 is connected to the first detection unit 81 in the position detection unit 80 and the light emitting unit 84 of the third detection unit 83. It is inserted between the light receiving parts 85.

  As described above, the through hole 47 of the mounting plate 45 provided for fixing the fixing bracket 41 to the building-side door pocket 180 opens larger than the diameter of the screw portion 91 a of the fixing bolt 91. Therefore, as shown in FIGS. 7 and 8, the mounting position of the fixing bracket 41 can be adjusted by slightly moving the fixing bracket 41 in the horizontal direction at the upper end portion of the building-side door pocket 180.

  As described above, the diameter of the through hole 47 of the fixing bracket 41 to which the shielding plate 42 is fixed is set larger than the diameter of the screw portion 91 a of the fixing bolt 91. Therefore, when the shielding plate 42 is fixed to the fixing bracket 41, as shown in FIG. 7, the position of the shielding plate 42 in the ascending / descending direction and the horizontal direction and the inclination with respect to the hoistway 110 can be adjusted. That is, the through hole 47 and the fixing bolt 91 of the fixing bracket 41 constitute an adjusting mechanism of the elevator 1 of this example.

  In addition, by fixing the shielding member 40 to the building-side door pocket 180, the building-side door pocket 180 serves as a reference in the height direction in the hoistway, and therefore, the rough positioning in the shielding member 40 is performed. Can do. Thereby, the height direction of the fixing bracket 41 and the shielding plate 42 can be easily adjusted.

  Further, as shown in FIG. 2, the gap between the building side door pocket 180 and the car side door pocket 121 is set to be narrow in order to prevent an object or a person from falling. In this example, the shielding piece 48 of the shielding member 40 protrudes in the gap between the building-side door pocket 180 and the car-side door pocket 121 without interfering with other spaces in the hoistway 110, and the position detection unit 80 is disposed. ing. Therefore, a space other than the gap between the building-side door pocket 180 and the car-side door pocket 121 in the hoistway 110 can be widened, and the degree of freedom in design can be increased when arranging other machines.

  Further, when the car 120 moves up and down, the shielding member 40 and the position detection unit 80 are connected to a long object such as a rope 130 disposed around the hoistway 110 and the car 120, a counterweight 140, and the like. Interference can be prevented.

  Next, the shielding member 20 for the top floor provided on the top floor will be described with reference to FIGS. 9 to 13B. In addition, about the structure which is common in the shielding member 40 for general floors, the description is abbreviate | omitted.

  FIG. 9 is a front view showing a state in which the vicinity of the upper part of the entrance / exit 202 on the top floor is viewed from the hoistway side. 10 to 13B show the shielding member 20 for the top floor, FIG. 10 is an exploded perspective view, FIG. 11A is a front view, FIG. 11B is a side view, FIG. 12 is a plan view, and FIG. TT line sectional drawing and FIG. 13B are SS line sectional views of FIG. 11B.

  As shown in FIG. 9, the shielding member 20 for the top floor is fixed to the upper end portion of the building-side door pocket 180 in the same manner as the shielding member 40 for the general floor. Further, the shielding member 20 for the top floor is erected upward from the building-side door pocket 180 along the ascending / descending direction, and is disposed between the building-side door pocket 180 and the ceiling portion 110 </ b> A of the hoistway 110.

  As shown in FIG. 10, the shielding member 20 for the top floor includes a fixing bracket 21, two shielding plates 22 </ b> A and 22 </ b> B, a connection bracket 31, two telescopic plates 32, a holding bracket 33, and a fixing bolt 91. And have. In addition, since the fixed bracket 21 has the same structure as the fixed bracket 41 of the shielding member 20 for general floors, the description thereof is omitted here. The fixing bracket 41 is provided with a through hole 27 through which the screw portion 91a of the fixing bolt 91 passes. The connection bracket 31 is fixed to the fixing bracket 41 via a fixing bolt 91.

  The connection bracket 31 is formed of a member having a U-shaped cross section in the horizontal direction. The connection bracket 31 includes two fixed pieces 31a and a rectangular connection piece 31b that connects the two fixed pieces 31a. The two fixing pieces 31a and the connecting piece 31b are provided with fixing holes 35, respectively.

  As shown in FIG. 11B and FIG. 13B, the end of the two fixing pieces 31 a opposite to the connecting end with the connecting piece 31 b is inserted between the two fixing plates 26 of the fixing bracket 21. At this time, the connection piece 31b of the connection bracket 31 faces the main surface plate 24 of the fixed bracket 21 with a gap therebetween. The connection bracket 31 is held by the fixing bracket 21 via the fixing screw 93 so that the attachment position and the inclination can be adjusted.

  As shown in FIG. 10, the two shielding plates 22 </ b> A and 22 </ b> B are formed of members having a U-shaped cross section in the horizontal direction. The two shielding plates 22 </ b> A and 22 </ b> B each have two shielding pieces 28 and a rectangular connecting piece 29 that connects the two shielding pieces 28. A first fixing hole 29 a is provided on one side in the longitudinal direction of the connecting piece 29, and a second fixing hole 29 b is provided on the other side in the longitudinal direction of the connecting piece 29.

  The length in the short direction of the connecting piece 29 in the shielding plates 22A and 22B is set to be approximately half the length in the short direction of the connecting piece 49 of the shielding plate 42 for the general floor. That is, the length in the short direction of the connecting piece 29 in the shielding plates 22 </ b> A and 22 </ b> B is approximately half of the length in the short direction of the main surface plate 24 of the fixing bracket 21.

  As shown in FIG. 13B, the connecting piece 29 of the shielding plates 22 </ b> A and 22 </ b> B contacts the connecting piece 31 b of the connecting bracket 31. 10 and 11A, the shielding plates 22A and 22B are fixed to the connection bracket 31 by screwing a fixing screw 93 into the first fixing hole 29a.

  The shielding plate 22A is disposed on one side of the connection piece 31b of the connection bracket 31 in the short direction, and the shielding plate 22B is disposed on the other side of the connection piece 31b of the connection bracket 31 in the short direction. The shielding plates 22A and 22B are arranged so that the longitudinal direction of the shielding piece 28 is substantially parallel to the ascending / descending direction. The shielding piece 28 protrudes toward the hoistway 110. At this time, as shown in FIG. 12, FIG. 13A and FIG. 13B, of the two shielding pieces 28 in the two shielding plates 22A and 22B, the neighboring shielding pieces 28 overlap each other and can be regarded as one shielding piece. it can. Then, as shown in FIGS. 3B and 3D, the shielding piece 28 that overlaps and contacts the horizontal direction is inserted into the second detection unit 82 of the position detection unit 80.

  A notch 28a is formed in the shielding piece 28 arranged on the other side in the short direction of the connection bracket 31 among the shielding pieces 28 of the shielding plate 22B. The notch 28a is formed with a predetermined length along the ascending / descending direction from one end in the longitudinal direction of the shielding piece 28, that is, the lower end in the ascending / descending direction.

  Therefore, as shown in FIGS. 11A and 13A, the number of shielding pieces 28 protruding into the hoistway 110 on the other side in the longitudinal direction of the shielding plates 22A and 22B, that is, on the upper side in the ascending / descending direction is three. 11A and 13B, the number of shielding pieces 28 protruding into the hoistway 110 on one side in the longitudinal direction of the shielding plates 22A and 22B, that is, on the lower side in the ascending / descending direction, is two. In addition, the two shielding pieces 28 and 28 which overlap and contact at the center in the horizontal direction are regarded as one shielding piece.

  Thus, by providing the notch 28a, the shield plate 22A and the shield plate 22B are horizontally overlapped and detected by the detectors 81, 82, and 83 of the position detector 80 as shown in FIGS. 3B and 3D. The number of the shielding pieces 28 to be changed can be changed. As a result, one shielding member 20 can be provided with a function as a limit switch for detecting the position of the car 120 and detecting overshoot.

  Further, as shown in FIGS. 11A and 13A, the two expansion plates 32 and the holding bracket 33 are fixed to the second fixing holes 29b of the two shielding plates 22A and 22B via fixing screws 93.

  The two stretchable plates 32 are each formed of a member having a U-shaped cross section in the horizontal direction. The telescopic plate 32 is slidably inserted between the two shielding pieces 28 in the shielding plates 22A and 22B. Further, the sliding surface portion 34 that contacts the connecting piece 29 of the shielding plates 22A and 22B in the telescopic plate 32 is provided with an attachment hole 34a that extends by a predetermined length along the longitudinal direction. A fixing screw 93 is inserted into the mounting hole 34a.

  Generally, it is necessary to adjust the length of the shielding plate according to the height of the ceiling portion 110A of the hoistway 110 from the building side door pocket 180. Conventionally, when the shielding plate is long, it is cut at the work site. In addition, when the shielding plate is short, a shielding plate corresponding to the length is newly produced or arranged.

  However, the elevator 1 of this example can easily change the length of the shielding member 20 in the ascending / descending direction by sliding the two extendable plates 32 in the ascending / descending direction along the shielding plates 22A and 22B. As a result, when the shielding member 20 is attached, the trouble of cutting the shielding plate or newly manufacturing it can be saved.

  Further, the other side in the longitudinal direction of the two shielding plates 22 </ b> A and 22 </ b> B and the two telescopic plates 32 are held by the holding bracket 33 via fixing screws 93. The holding bracket 33 is formed of a member having a U-shaped cross section in the horizontal direction.

The shielding member 60 includes a fixing bracket 61, two shielding plates 62, a connection bracket 71, and a fixing bolt 91. Since the structure of the fixing bracket 61 and the connection bracket 71 has the same structure as the fixing bracket 21 and the connection bracket 31 of the shielding member 20 for the top floor, the description thereof is omitted here.

  The two shielding plates 62 extend from the building-side door pocket 180 to the building-side door sill 181 along the ascending / descending direction. The upper side of the two shielding plates 62 in the up-and-down direction is fixed to the connection bracket 71 via a fixing screw 93, and the lower side of the up-and-down direction is fixed to the building-side door sill 181 via the fixing screw 93.

  Each of the two shielding plates 62 has two shielding pieces 68. The shielding piece 68 extends in the ascending / descending direction and protrudes toward the hoistway 110. Of the shielding pieces 68 of the two shielding plates 62, a notch 68a is formed in the shielding piece 68 located on one side in the horizontal direction. The notch 68a is formed with a predetermined length along the ascending / descending direction from the upper end of the shielding piece 68 in the ascending / descending direction.

  Therefore, as shown in FIG. 15A, the shielding plate 62 protrudes into the hoistway 110 on the other side in the longitudinal direction, that is, on the upper side in the ascending / descending direction, and the number of shielding pieces 68 is two. As shown in FIG. 15B, the number of shielding pieces 68 protruding into the hoistway 110 on one side in the longitudinal direction of the shielding plate 62, that is, on the lower side in the ascending / descending direction, is three. In addition, the two shielding pieces 68 and 68 which overlap and contact in the center in the horizontal direction are regarded as one shielding piece.

  In the shielding member 60 for the lowest floor having such a configuration, the shielding plate 62 is fixed to the building-side door pocket 180 at the upper part in the ascending / descending direction, and the lower part in the ascending / descending direction is fixed to the building-side door sill 181. The tilt cannot be adjusted. However, the lowermost floor shielding member 60 can perform horizontal alignment.

  The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention described in the claims.

  In the above-described embodiment, the example in which the position detector 80 is attached to the car-side door pocket 121 and the shielding member 20 for the top floor and the shielding member 40 for the general floor are attached to the building-side door pocket 180 has been described. However, the present invention is not limited to this. For example, the position detection unit 80 is fixed to the car-side door sill facing the car-side door pocket 121 of the car 120 in the up-and-down direction, and the shielding member 20 for the top floor and the shielding member 40 for the general floor are attached to the building-side door sill 181. It may be fixed.
