Description

[Technical Field]

[0001] TECHNICAL FIELD This disclosure relates to elevator cars, elevators, and methods of manufacturing elevator cars. [Background technology]

[0002] Conventionally, for example, an elevator car includes a car chamber with an opening, a car door that is movable between a closed position that closes the opening and an open position that opens the opening, a movable part that is movable relative to the car door, a connection part that connects the movable part to the tip of the car door so that the movable part is positioned at the tip position relative to the car door, and a detection part that detects when the movable part has moved relative to the car door to a detection position that is closer to the base end than the tip position (for example, Patent Document 1).

[0003] When the detector detects that the movable part has moved to the detection position, the car door, for example, returns to the open position. The elevator car disclosed in Patent Document 1 includes a facing part that faces the movable part, and when the car door is in the closed position, the movable part is separated from the facing part. This raises the risk that the movable part will not move to the detection position even if the car door moves to the closed position and the string is caught between the movable part and the facing part.

[0008] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0009] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] An embodiment of an elevator and an elevator car will be described below with reference to Figures 1 to 9. Note that the following embodiment is provided as an example to aid in understanding the configuration of the elevator and elevator car, and does not limit the configuration of the elevator and elevator car.

[0011] As shown in Fig. 1, an elevator 1 may include, for example, an elevator car (hereinafter simply referred to as "car") 2 for people (passengers) to ride in, a car drive unit 3 that drives the car 2, car rails 4 that guide the car 2, and a processing unit 5 that controls each part of the elevator 1. The drive system of the car drive unit 3 is not particularly limited.

[0012] For example, as in this embodiment, the elevator 1 may include a car rope 6 having a first end connected to the car 2, a counterweight 7 connected to a second end of the car rope 6, and a counterweight rail 8 that guides the counterweight 7. Then, as in this embodiment, the car drive unit 3 may include, for example, a sheave 3a around which the car rope 6 is wound, a drive source 3b (e.g., a motor) that rotates the sheave 3a, and a braking unit 3c (e.g., a brake) that brakes the sheave 3a.

[0013] That is, the car drive unit 3 may be a hoist and the elevator 1 may be a rope-type drive system. However, the present invention is not limited to such a configuration, and may be configured, for example, such that the car drive unit 3 is a hydraulic device and the elevator 1 is a hydraulic drive system, or such that the car drive unit 3 is a linear motor and the elevator 1 is a linear motor-type drive system.

[0014] Furthermore, in this embodiment, the first ends of the car ropes 6 are connected to the car 2, and the second ends of the car ropes 6 are connected to the counterweight 7, but the present invention is not limited to this configuration. For example, a configuration is also possible in which both ends of the car ropes 6 are fixed to the upper part or the lower part of the hoistway X1, and the car ropes 6 are wound around the sheaves of the car 2 and the counterweight 7, respectively, thereby connecting the car ropes 6 to the car 2 and the counterweight 7, respectively.

[0015] Furthermore, the elevator 1 according to this embodiment is configured such that the hoisting machine, which is the car drive unit 3, is disposed inside the machine room X2, but is not limited to such a configuration. For example, the elevator 1 may be configured such that the machine room X2 is not provided and the hoisting machine is disposed inside the hoistway X1.

[0016] In each drawing, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 that is a horizontal direction perpendicular to the first horizontal direction D1, and the third direction D3 is the up-down direction D3 that is perpendicular to each of the horizontal directions D1 and D2, and is the lifting direction in which the car 2 and the counterweight 7 move up and down. Although not particularly limited, the entrance / exit direction in which people move to enter and exit the car 2 may be, for example, the second horizontal direction D2 as in this embodiment.

[0017] The car 2 has a car chamber 2a having an interior space for passengers, and a car door 2b that moves in a first lateral direction D1 relative to the car chamber 2a. The car chamber 2a has a car opening 2c through which passengers enter and exit, and the car door 2b is movable between a closed position that closes the car opening 2c and an open position that opens the car opening 2c.

[0018] For example, as in this embodiment, the elevator 1 may include a hall opening 9 arranged at the hall X3 and a hall door 10 that opens and closes the hall opening 9. This allows a person to pass between the hall X3 and the car 2 by passing through the hall opening 9 and the car opening 2c.

[0019] The car 2 may be equipped with a door drive unit 2d that performs an opening and closing operation of the car door 2b. As a result, the door drive unit 2d moves the car door 2b, causing the car door 2b to open and close a car opening 2c of the car chamber 2a. Then, as the car door 2b opens and closes the car opening 2c of the car chamber 2a, the hall door 10 of the hall X3 where the car 2 is stopped opens and closes the hall opening 9 of the hall X3 in conjunction with the car door 2b, such a configuration may also be adopted.

[0020] As in the present embodiment, for example, the elevator 1 may be configured to include a hall operating panel 11 at the hall X3, and a car operating panel 2e inside the car 2. The processing unit 5 may then control the running of the car 2 and the opening and closing of the car doors 2b, for example, based on information input to the operating panels 2e and 11 (for example, destination floor information and door opening / closing information input to the car operating panel 2e, destination direction information input to the hall operating panel 11, etc.).

[0021] 2, the elevator 1 may include, for example, a landing threshold 12 disposed below the landing door 10. The landing threshold 12 may include, for example, a groove (not shown) extending in the first horizontal direction D1 to guide the lower end of the landing door 10 in the first horizontal direction D1. The elevator 1 may also include, for example, a landing opening frame 13 extending in the vertical direction D3 so as to form a part of the landing opening 9.

[0022] 2 to 4, the car 2 includes a car threshold 2f disposed below the car door 2b. The car threshold 2f may include, for example, a groove (not shown) extending in the first horizontal direction D1 to guide the lower end of the car door 2b in the first horizontal direction D1. The car 2 may also include a car opening frame 14 extending in the up-down direction D3 so as to form a part of the car opening 2c.

[0023] The number of each door 2b, 10 is not particularly limited, and may be, for example, two as in this embodiment, or may be one or three or more. The opening and closing method of the doors 2b, 10 is a method in which multiple doors 2b, 10 move in the same direction when opening and closing (one-side open type).

[0024] 3, the car 2 may include, for example, a car frame 2g that supports the car chamber 2a and a cover portion 2h that extends downward from a car threshold 2f. Note that the portion of the car 2 that includes the car chamber 2a and the portions fixed to the car chamber 2a (the car threshold 2f, car frame 2g, and cover portion 2h) is also referred to as the car main body.

[0025] 4, the car 2 may include, for example, a hanging portion 2i from which the car door 2b is hung, a roller 2j rotatably connected to the hanging portion 2i, and a guide 2k extending in the first horizontal direction D1 to guide the roller 2j. As a result, the upper end of the car door 2b is guided in the first horizontal direction D1 by the roller 2j and the guide 2k.

[0026] The car 2 includes a movable part 15 that is movable in the first lateral direction D1 relative to the car door 2b, a connection part 16 that connects the movable part 15 to the tip of the car door 2b, and a detection part 17 that detects the movement of the movable part 15. The movable part 15 is also called a safety, for example. The car 2 may also include a force application part 18 that applies force to the movable part 15, for example, as in this embodiment.

[0027] The first lateral direction D1 is also referred to as the opening / closing direction D1 in which the car door 2b moves to open and close the car opening 2c. Of the opening / closing direction D1, the direction in which the car door 2b moves to close the car opening 2c is referred to as the closing direction D1a, and of the opening / closing direction D1, the direction in which the car door 2b moves to open the car opening 2c is referred to as the opening direction D1b. Therefore, the tip of the car door 2b to which the movable part 15 is connected is the end of the car door 2b on the closing direction D1a side.

[0028] The movable part 15 includes a movable main body part 15a connected to the car door 2b by a connection part 16, and a fixed part 15b that is a separate part from the movable main body part 15a and is fixed to the lower end of the movable main body part 15a. This makes it possible to reduce the gap between the movable part 15 and the car threshold 2f. Therefore, the string can be reliably hooked at the tip part 15c of the movable part 15 (the end part on the closing direction D1a side).

[0029] Examples of strings that may be brought into the basket 2 include cords for vacuum cleaners and electrical appliances, strings for bags and bags, dog leads, etc. Although not particularly limited, the thickness of the strings is generally 4 mm or more, and for example, cords for vacuum cleaners and electrical appliances and strings for bags and bags are often 4 mm to 5 mm in thickness.

[0030] On the other hand, although not particularly limited, the dimension W4 of the gap between the tip end 15c of the movable part 15 and the car threshold 2f may be, for example, 3 mm or less, and is preferably, for example, 2 mm or less, and more preferably, for example, 1 mm or less. This allows the string to be reliably hooked on the tip end 15c of the movable part 15. Therefore, for example, it is possible to prevent the string from getting between the movable part 15 and the car threshold 2f.

[0031] For example, as in the present embodiment, the connecting part 16 may include a link 16a that is rotatably connected to each of the car door 2b and the movable part 15. However, the connecting part 16 is not limited to such a configuration, and is not particularly limited as long as it is configured to connect the movable part 15 to the car door 2b so that the movable part 15 is movable in the first lateral direction D1 relative to the car door 2b.

[0032] The detection unit 17 may include, for example, a contact sensor 17a (for example, a limit switch) that detects contact of the link 16a, as in the present embodiment. However, the detection unit 17 is not limited to such a configuration, and is not particularly limited as long as it is configured to detect movement of the movable part 15 relative to the car door 2b.

[0033] The force application unit 18 may be, for example, an elastic body that applies an elastic restoring force to the movable unit 15. Although not particularly limited, the force application unit 18 may be, for example, as in this embodiment, a torsion spring having a first end hooked to the link 16a and a second end fixed to the car door 2b.

[0034] 5(a), when no external force is applied to the movable part 15, the force application part 18 applies a force to the movable part 15, so that the movable part 15 is located at a tip position relative to the car door 2b. Note that, although not particularly limited, for example, when the force application part 18 is not provided and no external force is applied to the movable part 15, the connection part 16 may be located at a tip position relative to the car door 2b by its own weight.

[0035] When the movable part 15 is located at the tip end position, the contact sensor 17a is pressed by the link 16a and is in the ON state. The distance in the first horizontal direction D1 between the tip of the movable part 15 located at the tip end position and the tip of the car door 2b is a first distance W1.

[0036] 5(b), when a force F1 in the opening direction D1b is applied to the movable part 15, the movable part 15 moves toward the base end (toward the opening direction D1b) relative to the car door 2b. When the movable part 15 moves to the detection position relative to the car door 2b, the contact sensor 17a moves away from the link 16a and enters the OFF state, and the detection part 17 detects that the movable part 15 has moved to the detection position.

[0037] As a result, for example, car door 2b is moved to the open position by processing unit 5. Therefore, for example, if a person hits movable part 15, car door 2b moves to open car opening 2c, thereby preventing the person from being pinched between car door 2b and car opening frame 14. Note that the distance in first lateral direction D1 between the tip of movable part 15 located at the detection position and the tip of car door 2b is a second distance W2 that is shorter than first distance W1.

[0038] Furthermore, in this way, the movable part 15 moves to the detection position by moving the distance between the tip position and the detection position (i.e., the difference between the first distance W1 and the second distance W2). This makes it possible to prevent the movable part 15 from moving unnecessarily to the detection position due to, for example, the movable part 15 swinging while the car door 2b is moving.

[0039] Although not particularly limited, the distance between the tip position and the detection position (i.e., the difference between the first distance W1 and the second distance W2) may be, for example, 5 mm or more. This makes it possible to reliably prevent the movable part 15 from moving unnecessarily to the detection position, for example, when the car door 2b is moving between the open position and the closed position.

[0040] Although not particularly limited, the distance between the tip position and the detection position (i.e., the difference between the first distance W1 and the second distance W2) may be, for example, 10 mm or less, which allows the presence of a person or object between the movable part 15 and the car opening frame 14 to be appropriately detected.

[0041] 5 and 6, the presence of the fixed portion 15b reduces the gap between the movable portion 15 and the car threshold 2f, which may cause foreign objects such as pebbles to become caught between the movable portion 15 and the car threshold 2f.

[0042] In contrast, the lower end 15d of the movable part 15 is formed to be inclined upward from the tip end 15c to the base end 15e of the movable part 15. As a result, the gap between the lower end 15d of the movable part 15 and the car threshold 2f becomes larger from the tip end 15c of the movable part 15 to the base end 15e.

[0043] Therefore, for example, when the car door 2b and the movable part 15 are moving in the closing direction D1a, if the movable part 15 runs up a foreign object that has entered the gap between the lower end 15d of the movable part 15 and the car threshold 2f, the foreign object is more likely to be guided from the tip end 15c to the base end 15e of the movable part 15. Therefore, for example, it is possible to prevent the foreign object from getting caught between the movable part 15 and the car threshold 2f.

[0044] Moreover, the movable part 15 is connected to the car door 2b by a rotating link 16a. As a result, when the movable part 15 moves in the opening direction D1b relative to the car door 2b (i.e., when it moves from the tip position toward the detection position), it moves upward relative to the car door 2b.

[0045] Therefore, for example, if a foreign object enters the gap between the lower end 15d of the movable part 15 and the car threshold 2f while the car door 2b and the movable part 15 are moving in the closing direction D1a, the foreign object will push the movable part 15 in the opening direction D1b, causing the movable part 15 to move upward while moving in the opening direction D1b relative to the car door 2b. Therefore, the movable part 15 will ride up the foreign object, further preventing the foreign object from getting caught between the movable part 15 and the car threshold 2f.

[0046] 6, the landing opening frame 13 may include, for example, a landing door abutment 13a that faces the landing door 10 in the first horizontal direction D1. The landing door abutment 13a may include, for example, a buffer portion (e.g., rubber) 13b as in this embodiment. The landing door 10 may abut against the buffer portion 13b when it is located at a closed position that closes the landing opening 9, for example.

[0047] The car opening frame 14 may, for example, as in this embodiment, include a car door abutment 14a that faces the car door 2b in the first horizontal direction D1. The car door abutment 14a may, for example, as in this embodiment, include a buffer portion (e.g., rubber) 14b. The car door 2b may abut against the buffer portion 14b when it is located at a closed position that closes the car opening 2c, for example.

[0048] The car opening frame 14 also includes a facing portion 14c that faces the movable portion 15 in the first horizontal direction D1. The facing portion 14c includes a base portion 14d that is disposed at a position away from the movable portion 15 in the first horizontal direction D1, and a movable abutment portion 14e that is a separate part from the base portion 14d and is fixed to the base portion 14d, and that comes into contact with the movable portion 15 when the car door 2b is positioned in the closed position.

[0049] Although not particularly limited, the base portion 14d may be formed in a plate shape extending along the second lateral direction D2 and the vertical direction D3, as in the present embodiment. Furthermore, although not particularly limited, the movable abutment portion 14e may be formed in a square tube shape extending along the vertical direction D3, as in the present embodiment.

[0050] 7(a), when the car door 2b is in the closed position, the tip end 15c of the movable part 15 abuts the movable abutment part 14e of the facing part 14c, and the movable part 15 is therefore located at an intermediate position relative to the car door 2b between the tip end position (see FIG. 5(a)) and the detection position (see FIG. 5(b)). Note that the distance in the first lateral direction D1 between the tip end of the movable part 15 located at the intermediate position and the tip end of the car door 2b is a third distance W3 that is shorter than the first distance W1 and longer than the second distance W2.

[0051] As a result, when the car door 2b is in the closed position, the movable part 15 moves to the detection position by the distance between the intermediate position and the detection position (i.e., the difference between the third distance W3 and the second distance W2). Therefore, as shown in Fig. 7(b), even if the string Y1 is caught between the movable part 15 and the movable abutment 14e of the facing part 14c, the movable part 15 can be reliably moved to the detection position. Therefore, even if the string Y1 is caught between the movable part 15 and the facing part 14c, for example, it is possible to reliably detect that the string Y1 is caught.

[0052] Although not particularly limited, the distance between the intermediate position and the detection position (i.e., the difference between the third distance W3 and the second distance W2) may be, for example, 3 mm or less. This allows reliable detection of the string Y1 being caught between the movable part 15 and the facing part 14c, even if a thin string Y1 having a thickness of, for example, 4 mm to 5 mm, is caught between the movable part 15 and the facing part 14c.

[0053] Furthermore, while the string Y1 generally rests on the car threshold 2f, for example, as shown in Fig. 4, the tip of the fixed part 15b (the end in the closing direction D1a) may be at the same position as the tip of the movable main body part 15a (the end in the closing direction D1a) in the first lateral direction D1. This allows the movable part 15 to be reliably moved to the detection position, for example, when the string Y1 is caught between the fixed part 15b and the facing part 14c.

[0054] Next, a method for manufacturing the elevator car 2 according to this embodiment will be described. Note that the following method is provided as an example to facilitate understanding of the manufacturing method of the elevator car 2, and is not intended to limit the manufacturing method of the elevator car 2.

[0055] 8, for example, in an existing car, the facing portion 14c of the car opening frame 14 is composed of only the base portion 14d. In such a configuration, when the car door 2b is positioned in the closed position, the movable portion 15 is separated from the facing portion 14c (base portion 14d).

[0056] Therefore, as shown in Fig. 6, the movable abutment 14e is fixed to the base portion 14d. This allows the movable portion 15 to abut against the facing portion 14c when the car door 2b is in the closed position. The method for fixing the movable abutment 14e to the base portion 14d is not particularly limited, and may be, for example, adhesion with an adhesive, fastening with fastening means (for example, bolts and nuts), or welding.

[0057] 9, for example, in an existing car, the movable part 15 is composed only of the movable main body part 15a. In such a configuration, the gap between the movable part 15 and the car threshold 2f is large. Although not particularly limited, the dimension W5 of the gap is, for example, 6 mm or more.

[0058] Therefore, as shown in Fig. 4, fixed portion 15b is fixed to the lower end of movable main body portion 15a. This makes it possible to reduce the gap between movable portion 15 and car threshold 2f. Note that the method for fixing fixed portion 15b to movable main body portion 15a is not particularly limited, and may be, for example, adhesion with an adhesive, fastening with fastening means (for example, bolts and nuts), or welding.

[0059] [1] As described above, the elevator car 2, as in this embodiment, a cage 2a having an opening 2c; a car door (2b) that is movable between a closed position that closes the opening (2c) and an open position that opens the opening (2c) by moving in a first lateral direction (D1) relative to the car chamber (2a); a movable portion 15 movable in the first horizontal direction D1 relative to the car door 2b; a connection portion 16 that connects the movable portion 15 to a tip end portion of the car door 2b so that the movable portion 15 is located at a tip end position relative to the car door 2b; a detection unit 17 that detects that the movable unit 15 has moved relative to the car door 2b to a detection position closer to the base end than the tip position; a facing portion 14c facing the movable portion 15 in the first horizontal direction D1, The movable portion 15 abuts against the facing portion 14c when the car door 2b is located at the closed position. This configuration is preferable.

[0060] According to this configuration, when the car door 2b is in the closed position, the movable part 15 abuts against the facing part 14c. As a result, if the string Y1 is caught between the movable part 15 and the facing part 14c, the movable part 15 can be moved to the detection position.

[0061] [2] In addition, in the elevator car 2 of the above [1], as in this embodiment, When the car door 2b is located at the closed position, the movable part 15 is located at an intermediate position between the tip position and the detection position with respect to the car door 2b. This configuration is preferable.

[0062] With this configuration, when the car door 2b is in the closed position, the movable part 15 moves to the detection position by the distance between the intermediate position and the detection position. This makes it possible to reliably move the movable part 15 to the detection position when the string Y1 is caught between the movable part 15 and the facing part 14c.

[0063] On the other hand, when the car door 2b is moving between the open position and the closed position, the movable part 15 moves to the detection position by the distance between the tip position and the detection position. This makes it possible to prevent the movable part 15 from moving unnecessarily to the detection position when the car door 2b is moving.

[0064] [3] In addition, in the elevator car 2 of the above [1] or [2], as in this embodiment, The facing portion 14c is a base portion 14d that is disposed at a position away from the movable portion 15 when the car door 2b is located at the closed position; a movable abutment 14e that is a separate part from the base portion 14d, is fixed to the base portion 14d, and abuts against the movable portion 15 when the car door 2b is located at the closed position; This configuration is preferable.

[0065] According to this configuration, the movable abutment 14e is a separate part from the base portion 14d and is fixed to the base portion 14d, so that when the car door 2b is in the closed position, the movable portion 15 can abut against the movable abutment 14e of the facing portion 14c.

[0066] [4] In addition, any one of the elevator car 2 of the above [1] to [3], as in this embodiment, A car sill 2f is provided below the movable part 15, The movable part 15 is a movable main body portion 15a connected to the car door 2b by the connecting portion 16; and a fixed portion 15b which is a separate part from the movable main body portion 15a and is fixed to the lower end of the movable main body portion 15a. This configuration is preferable.

[0067] With this configuration, the fixed portion 15b is fixed to the lower end of the movable main body portion 15a, so that the gap between the movable portion 15 and the car threshold 2f can be reduced. As a result, when the string Y1 is positioned between the movable portion 15 and the facing portion 14c, the string Y1 can be reliably hooked by the tip end 15c of the movable portion 15.

[0077] (C) Furthermore, in the elevator car 2 according to the above embodiment, the movable part 15 is configured to include the movable main body part 15a and the fixed part 15b, which are separate parts. However, the elevator car 2 is not limited to this configuration. For example, the movable part 15 may be configured as a single part.

[0078] (D) Furthermore, in the elevator car 2 according to the above embodiment, the tip of the fixed portion 15b (the end in the closing direction D1a) is at the same position as the tip of the movable main body portion 15a (the end in the closing direction D1a) in the first horizontal direction D1. However, the elevator car 2 is not limited to this configuration.

[0079] For example, the tip of the fixed portion 15b may be configured to protrude from the tip of the movable main body portion 15a in the first horizontal direction D1, i.e., to be located closer to the closing direction D1a than the tip of the movable main body portion 15a. Alternatively, the tip of the fixed portion 15b may be configured to be recessed from the tip of the movable main body portion 15a in the first horizontal direction D1, i.e., to be located closer to the opening direction D1b than the tip of the movable main body portion 15a.

[0080] (E) Furthermore, in the elevator car 2 according to the above embodiment, the lower end 15d of the movable part 15 is configured to be inclined upward from the tip end 15c to the base end 15e of the movable part 15. However, the elevator car 2 is not limited to this configuration.

[0081] For example, the lower end 15d of the movable part 15 may be configured to be parallel to the car threshold 2f from the tip end 15c to the base end 15e of the movable part 15. Also, for example, the lower end 15d of the movable part 15 may be configured to be inclined downward from the tip end 15c of the movable part 15 to the base end 15e.

[0082] (F) Furthermore, in the elevator car 2 according to the above embodiment, the connection part 16 is configured to include a link 16a rotatably connected to the car door 2b and the movable part 15 so that the movable part 15 moves upward relative to the car door 2b when the movable part 15 moves from the tip position toward the detection position (in the opening direction D1b) relative to the car door 2b. However, the elevator car 2 is not limited to this configuration.

[0083] For example, the movable part 15 may be configured to move parallel to the car door 2b in the first horizontal direction (opening / closing direction) D1. Although there are no particular limitations to this configuration, for example, the connection part 16 may be configured to include a roller rotatably connected to the movable part 15 and a guide rail fixed to the car door 2b to guide the roller in the first horizontal direction (opening / closing direction) D1.

[0084] (G) Furthermore, in the manufacturing method of the elevator car 2 according to the above embodiment, the movable abutment portion 14e is fixed to the base portion 14d. However, the manufacturing method of the elevator car 2 is not limited to this method. For example, a method in which an additional part is fixed to the tip of the movable main body portion 15a may also be used. Then, when the car door 2b is in the closed position, the additional part may abut against the facing portion 14c (base portion 14d).

[0085] (H) For example, the order of execution of each step, such as the operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, can be implemented in any order, as long as the result of a previous step is not used in a subsequent step. For example, even if a description is made using "first," "next," etc. for convenience, this does not mean that the steps must be executed in that order. [Explanation of symbols]
