Embodiments for Carrying Out the Invention

[0022] Hereinafter, an embodiment of an elevator including a landing door engaging device and a door lock device of a car door according to the present invention will be described. In the following, notations such as "first", "second", "third", etc. are used, but this is for the purpose of indicating that they are different from each other, and the numbers themselves do not have any particular meaning.

[0023] As shown in FIG. 1, the elevator 1 includes a hoistway 2 and a car 3. The hoistway 2 extends vertically in a building having floors. The car 3 moves up and down in the hoistway 2 by the drive of a drive mechanism and stops at a designated floor when the drive of the drive mechanism stops.

[0024] The car 3 includes a car door device 30. The car door device 30 includes a car door 31, a door support structure 32, and a door opening / closing device 35. The car door 31 moves in the left-right direction (the left and right horizontal directions, the same hereinafter) to open and close the opening (car entrance) in the front of the car 3 to enable people to get on and off. The door support structure 32 is a structure that supports the car door 31 while enabling the opening / closing operation of the car door 31. The door opening / closing device 35 is a device for opening and closing the car door 31.

[0025] In contrast, the landing 20 on each floor is provided with a three-sided frame 21 and a landing door device 22. The three-sided frame 21 is formed on the wall surface, and the opening inside the frame has a size corresponding to the opening of the car 3. The landing door device 22 includes a landing door 23 and a door support structure 24. The landing door 23 moves in the left-right direction to open and close the opening (landing entrance and exit) inside the three-sided frame 21 to enable people to get on and off. The landing door 23 is normally biased by an elastic force to be in the closed state, and is opened against the elastic bias following the opening operation of the car door 31 of the car 3 stopped on the floor, and is closed by the elastic bias along with the closing operation of the car door 31. The door support structure 24 is a structure that supports the landing door 23 while enabling the opening and closing operation of the landing door 23.

[0026] As shown in FIG. 2, the car door 31 includes a door panel 310, a door hanger 311, and a connecting body 313. The door panel 310 is arranged along the vertical plane and is the main body of the car door 31 that opens and closes the opening 3a of the car 3. The door hanger 311 is integrally attached to the upper end portion of the door panel 310. The door hanger 311 is provided with a pair of rollers 312, 312. The pair of rollers 312, 312 are arranged at intervals in the left-right direction at the upper end portion of the door hanger 311. The connecting body 313 is attached between the pair of rollers 312, 312 at the upper end portion of the door hanger 311. The connecting body 313 is a device that connects the car door 31 (the door hanger 311 thereof) to a drive belt 353 of a door opening and closing device 35 described later.

[0027] The door support structure 32 includes a door rail 33 and a threshold 34. The door rail 33 is a straight and long plate-like member, which is provided in the horizontal direction at the upper front part of the cage 3. When the rollers 312, 312 of the door hanger 311 are placed on the upper edge of the door rail 33, the cage door 31 is suspended from the door rail 33 in a state where it can slide in the horizontal direction along the door rail 33. The door rail 33 is a structure that supports the upper part of the cage door 31 while enabling the opening and closing operation of the cage door 31. On the other hand, the threshold 34 is provided in the horizontal direction at the lower front part of the cage 3 along the lower edge of the opening 3a of the cage 3 and with both ends extending horizontally beyond the lower edge of the opening 3a. The threshold 34 is a structure that supports the lower part of the cage door 31 while enabling the opening and closing operation of the cage door 31.

[0028] The door opening / closing device 35 includes a drive motor 350, a drive pulley 351, a driven pulley 352, and a drive belt 353. The drive motor 350 is provided at one end side, either left or right, of the upper front part of the cage 3. The drive pulley 351 is provided coaxially and integrally with the drive shaft of the drive motor 350. The driven pulley 352 is provided at the other end side, either left or right, of the upper front part of the cage 3. The drive belt 353 is an endless belt wound between the drive pulley 351 and the driven pulley 352. The drive belt 353 is provided in the horizontal direction and is provided parallel to the door rail 33.

[0029] When the drive motor 350 is driven, the drive pulley 351 rotates, and accordingly, the drive belt 353 moves in a circulating manner. Thereby, the two left and right cage doors 31, 31 reciprocate along the door rail 33 and perform an opening and closing operation. One cage door 31 is connected to one side of the drive belt 353 by a connecting body 313, and the other cage door 31 is connected to the other side of the drive belt 353 by the connecting body 313. Thereby, the pair of cage doors 31, 31 move in opposite directions to each other. That is, the cage door device 30 and the landing door device 22 are of the center open type in which the opening 3a of the cage 3 opens from the center.

[0030] The car door device 30 includes a landing door engaging device 36 and a door locking device 38. The landing door engaging device 36 is a device that, when the car door 31 is opened (and closed), engages with the engaged body of the landing door 23, and causes the landing door 23 to open (and close) along with the opening (and closing) operation of the car door 31. The door locking device 38 is a device that restricts the opening operation of the car door 31 in the fully closed state. Details of the landing door engaging device 36 and the car door locking device 38 will be described later.

[0031] As shown in FIG. 3, the landing door 23 and the door support structure 24 also have the same structure as the car door 31 and the door support structure 32. Therefore, the description of the landing door 23 and the door support structure 24 will be omitted as being the same as the above description of the car door 31 and the door support structure 32.

[0032] The landing door device 22 includes the above-described engaged body 27 and a door locking device 28. The engaged body 27 is the part with which the landing door engaging device 36 of the car door device 30 engages, as described above. The door locking device 28 is a device that restricts the opening operation of the landing door 23 in the fully closed state.

[0033] As shown in FIG. 4, the engaged body 27 is in the form of rollers 27A and 27B. The roller 27A is provided on a swing arm 2830, which will be described later, as a first roller and a movable roller. The roller 27B is provided in the vicinity of the roller 27A at a location other than the swing arm 2830 as a second roller and a fixed roller. The rollers 27A and 27B are rotatably provided about an axis perpendicular to the vertical plane of the landing door 23.

[0034] The door locking device 28 includes a locked body 280 and a switch 281 of a door closed detection unit on the landing entrance side, and a lock body 282, an operating body 283, and a connecting bar 285 on the landing door 23 side.

[0035] The locked body 280 and the switch 281 are directly or indirectly attached to the inner wall surface 2A of the hoistway 2 around the landing entrance and exit via a mounting plate, bracket, frame, or the like. The locked body 280 and the switch 281 are provided in an upper region of the inner edge of the landing door 23 in a fully closed state (the side edge of the left and right side edges of the landing door 23 that closes the landing entrance and exit). The locked body 280 is a plate-like member along a direction intersecting the opening and closing direction of the landing door 23. The switch 281 is in the form of an interlock switch that constitutes a part of the safety circuit of the drive device of the elevator 1.

[0036] The locking body 282 is directly or indirectly attached to the door hanger 231 (outer surface) via a mounting plate or the like. The locking body 282 is swingably provided at a first part (for example, the base end part) of the locking body 282. The locking body 282 is rotatably provided between a first state (FIG. 4(a)) in which the height position of the second part (for example, the tip part) of the locking body 282 decreases and the inclination becomes smaller (for example, horizontal), and a second state (FIG. 4(b)) in which the height position of the second part of the locking body 282 increases and the inclination becomes larger. The locking body 282 is rotatably provided about an axis orthogonal to the vertical plane of the landing door 23.

[0037] The locking body 282 includes a locking portion 282a. The locking portion 282a is a claw-like portion protruding downward from the main body of the locking body 282. In the first state of the locking body 282, the locking portion 282a is at the same height position as the locked body 280 and can engage with the locked body 280 in the opening direction of the landing door 23, thereby restricting the opening operation of the landing door 23 in a fully closed state (locking state). On the other hand, in the second state of the locking body 282, the locking portion 282a is located above the locked body 280 and cannot engage with the locked body 280 in the opening direction of the landing door 23, thereby allowing the opening operation of the landing door 23 in a fully closed state (unlocking state).

[0038] The locking body 282 includes a conductor portion 282b. The conductor portion 282b is attached to the second part of the locking body 282. When the locking body 282 is in the locked state, the conductor portion 282b contacts and acts on a pair of terminals (not shown) of the switch 281 to turn the switch 281 ON (or OFF). The control unit of the elevator 1 determines that the locking body 282 is in the locked state based on the ON signal (or OFF signal) of the switch 281. As a result, the control unit of the elevator 1 determines that the landing door 23 is in the fully closed state. On the other hand, when the locking body 282 is in the unlocked state, the conductor portion 282b separates from the pair of terminals of the switch 281 to turn the switch 281 OFF (or ON). The control unit of the elevator 1 determines that the locking body 282 is in the unlocked state based on the OFF signal (or ON signal) of the switch 281. As a result, the control unit of the elevator 1 determines that the landing door 23 is not in the fully closed state.

[0039] The operating body 283 is disposed at a position below the landing door 23 than the locking body 282, and performs a switching operation between the locked state and the unlocked state of the locking body 282 via the connecting bar 285. The operating body 283 is attached directly to the door panel 230 (outer surface) or indirectly via a mounting plate 284 or the like.

[0040] The operating body 283 includes the roller 27A described above and a swing arm 2830. The swing arm 2830 is provided so as to be swingable at a first part (for example, the base end portion) of the swing arm 2830. The swing arm 2830 is provided so as to be rotatable between a first state (FIG. 4(a)) corresponding to the first state (locked state) of the locking body 282 and a second state (FIG. 4(b)) corresponding to the second state (unlocked state) of the locking body 282. The roller 27A is provided at a second part (for example, the tip portion) of the swing arm 2830. The roller 27A and the swing arm 2830 are provided so as to be rotatable about an axis in a direction perpendicular to the vertical plane of the landing door 23.

[0041] The connecting bar 285 connects the locking body 282 and the operating body 283. The connecting bar 285 is a straight and long plate-shaped member. The connecting bar 285 is arranged along the vertical direction (including the direction inclined to a certain extent with respect to the vertical direction) between the locking body 282 and the operating body 283 with the locking body 282 arranged above and the operating body 283 arranged below. The connecting bar 285 is rotatably connected to the third part (for example, the middle part) of the locking body 282 at the first part (for example, one end (upper end)) of the connecting bar 285, and is rotatably connected to the third part (for example, the tip of the protruding piece protruding laterally from the middle part) of the swing arm 2830 at the second part (for example, the other end (lower end)) of the connecting bar 285. Thereby, the connecting bar 285 constitutes a link between the locking body 282 and the operating body 283.

[0042] As shown in FIGS. 5 and 6, the landing door engaging device 36 includes a contact body 360 as a configuration on the car entrance side, and includes a first cam 361, a second cam 363, an operating body 369, and a connecting bar 370 as configurations on the car door 31 side.

[0043] The contact body 360 is directly or indirectly attached to the front surface of the car 3 around the car entrance via a mounting plate, bracket, frame, etc. The contact body 360 is provided in the upper region of the inner edge of the car door 31 in the fully closed state (the side edge on the side closing the car entrance among the left and right side edges of the car door 31). The contact body 360 is a member having a cam portion 360a inclined with respect to the opening and closing direction of the car door 31. The contact body 360 is a long plate-shaped member with the tip side bent, and the bent portion becomes the cam portion 360a.

[0044] The first cam 361 and the second cam 363 are a form of engaging members that engage with the engaged member 27 of the landing door device 22. The first cam 361 and the second cam 363 are attached directly to the door panel 310 (outer surface) or indirectly via a mounting plate 365 or the like. The first cam 361 and the second cam 363 are members that are long along the vertical direction and are arranged in parallel with a predetermined interval in the left - right direction. The first cam 361 and the second cam 363 are angle members having a long plate - like portion along the vertical plane of the car door 31 and a long plate - like portion (cam portion) orthogonal to the vertical plane of the car door 31. The first cam 361 and the second cam 363 are, for example, metal members made of iron, steel, stainless steel, or aluminum.

[0045] The first cam 361 is provided so as to be movable between a first state (FIG. 5) and a second state (FIG. 6) closer to the inner edge of the car door 31 than the first state. The second cam 363 is provided so as to be movable between a first state (FIG. 5) and a second state (FIG. 6) closer to the inner edge of the car door 31 and the first cam 361 than the first state, and the interval (width) between the second cam 363 and the first cam 361 becomes narrower. For this reason, the first cam 361 and the second cam 363 are also called movable cams.

[0046] The first cam 361 constitutes one link of a parallel crank mechanism or a parallel link mechanism and is provided so as to be translatable by a pair of parallel links 362, 362. The second cam 363 constitutes one link of a parallel crank mechanism or a parallel link mechanism and is provided so as to be translatable by a pair of parallel links 364, 364. Each joint of the mechanism is provided so as to be rotatable about an axis in a direction orthogonal to the vertical plane of the car door 31. Thereby, the first cam 361 and the second cam 363 are each provided so as to be independently translatable along the vertical plane of the car door 31.

[0047] The first cam 361 swings between a first state (FIG. 5) in which a pair of parallel links 362, 362 are inclined obliquely and a second state (FIG. 6) in which the inclination becomes (slightly) larger, and the mechanism changes states, thereby switching between the first state and the second state. The second cam 363 swings between a first state (FIG. 5) in which a pair of parallel links 364, 364 are inclined obliquely and a second state (FIG. 6) in which the inclination becomes smaller (for example, horizontal), and the mechanism changes states, thereby switching between the first state and the second state. The swing angle is larger for the parallel link 364 than for the parallel link 362. For this reason, the stroke of the translation is larger for the second cam 363 than for the first cam 361.

[0048] When the landing door engaging device 36 is not operating (when the car door 31 is fully closed), the first cam 361 is in the first state due to its own weight, and when the landing door engaging device 36 is operating (when the car door 31 is opening), it switches from the first state to the second state so as to face obliquely upward. When the landing door engaging device 36 is not operating, the second cam 363 is in the first state, and when the landing door engaging device 36 is operating, it switches from the first state to the second state so as to face obliquely downward due to its own weight.

[0049] The first state of the first cam 361 is defined by the stopper 366, and the second state of the first cam 361 is defined by the stopper 367. The second state of the second cam 363 is defined by the stopper 368. Each of the stoppers 366 to 368 is position adjustable (the protruding length is adjustable), and the positions of the first state and the second state of the first cam 361 and the position of the second state of the second cam 363 are adjustable.

[0050] The operating body 369 is disposed above the car door 31 relative to the second cam 363, and performs a switching operation between the first state and the second state of the second cam 363 via the connecting bar 370. The operating body 369 is attached directly to the door hanger 311 (outer surface) or indirectly via a mounting plate or the like.

[0051] The operating body 369 includes a roller 3690 and a swing arm 3691. As the cage door 31 opens, the roller 3690 moves away from the cam portion 360a of the contact body 360. On the other hand, as the cage door 31 closes, the roller 3690 contacts the cam portion 360a and moves thereon. The swing arm 3691 is provided so as to be swingable at a first portion (for example, an intermediate portion) of the swing arm 3691. The swing arm 3691 is provided so as to be rotatable between a first state (FIG. 5) corresponding to the first state of the second cam 363 and a second state (FIG. 6) corresponding to the second state of the second cam 363. The roller 3690 is provided at a second portion (for example, one end portion) of the swing arm 3691. The roller 3690 and the swing arm 3691 are provided so as to be rotatable about an axis in a direction perpendicular to the vertical plane of the cage door 31.

[0052] The connecting bar 370 connects the second cam 363 and the operating body 369. The connecting bar 370 is a straight and long plate-like member. With the second cam 363 disposed below and the operating body 369 disposed above, the connecting bar 370 is disposed along the vertical direction (including a direction slightly inclined with respect to the vertical direction) between the second cam 363 and the operating body 369. The connecting bar 370 is rotatably connected to a first portion (for example, one end portion (lower end portion)) of the second cam 363 at a first portion (for example, one end portion (lower end portion)) of the connecting bar 370, and is rotatably connected to a third portion (for example, the other end portion) of the swing arm 3691 at a second portion (for example, the other end portion (upper end portion)) of the connecting bar 370. Thereby, the connecting bar 370 constitutes a link between the second cam 363 and the operating body 369.

[0053] The door lock device 38 includes, as a configuration on the cage entrance side, a body to be locked 380 and a switch 381 of the door closed detection unit, and includes, as a configuration on the cage door 31 side, a locking body 382, the above-described first cam 361, and a connecting bar 390.

[0054] The locked body 380 and the switch 381 are directly or indirectly attached to the front surface of the car 3 around the car entrance and exit via a mounting plate, bracket, frame, etc. The locked body 380 and the switch 381 are provided in the upper region above the inner edge of the fully closed car door 31. The locked body 380 is a plate-like member along a direction intersecting the opening and closing direction of the car door 31. The switch 381 is in the form of an interlock switch that constitutes a part of the safety circuit of the driving device of the elevator 1.

[0055] The locking body 382 is directly or indirectly attached to the door hanger 311 (outer surface) via a mounting plate or the like. The locking body 382 is provided swingably at the first part (for example, the base end part) of the locking body 382. The locking body 382 is rotatably provided between a first state (Fig. 5) in which the height position of the second part (for example, the tip part) of the locking body 382 is lowered and the inclination becomes smaller (for example, horizontal), and a second state (Fig. 6) in which the height position of the second part of the locking body 382 is raised and the inclination becomes larger. The locking body 382 is rotatably provided about an axis orthogonal to the vertical plane of the car door 31.

[0056] The locking body 382 includes a locking part 382a. The locking part 382a is a claw-like part protruding downward from the main body of the locking body 382. In the first state of the locking body 382, the locking part 382a is at the same height position as the locked body 380 and can engage with the locked body 380 in the opening direction of the car door 31, thereby restricting the opening operation of the fully closed car door 31 (locking state). On the other hand, in the second state of the locking body 382, the locking part 382a is located above the locked body 380 and cannot engage with the locked body 380 in the opening direction of the car door 31, thereby allowing the opening operation of the fully closed car door 31 (unlocking state).

[0057] The locking body 382 includes a conductor portion 382b. The conductor portion 382b is attached to the second part of the locking body 382. When the locking body 382 is in the locked state, the conductor portion 382b contacts and acts on a pair of terminals of the switch 381, turning the switch 381 ON (or OFF). Based on the ON signal (or OFF signal) of the switch 381, the control unit of the elevator 1 determines that the locking body 382 is in the locked state. As a result, the control unit of the elevator 1 determines that the car door 31 is in the fully closed state. On the other hand, when the locking body 382 is in the unlocked state, the conductor portion 382b separates from a pair of terminals of the switch 381, turning the switch 381 OFF (or ON). Based on the OFF signal (or ON signal) of the switch 381, the control unit of the elevator 1 determines that the locking body 382 is in the unlocked state. As a result, the control unit of the elevator 1 determines that the car door 31 is not in the fully closed state.

[0058] The first cam 361 is a form of the operating body. The first cam 361 is disposed at a position below the car door 31 than the locking body 382, and performs a switching operation between the locked state and the unlocked state of the locking body 382 via the connecting bar 390.

[0059] The connecting bar 390 connects the locking body 382 and the first cam 361. The connecting bar 390 is a straight and long plate-like member. The connecting bar 390 is arranged along the vertical direction (including a direction inclined to a certain extent with respect to the vertical direction) between the locking body 382 and the first cam 361 by arranging the locking body 382 above and the first cam 361 below. The connecting bar 390 is rotatably connected to the third part (for example, the middle part) of the locking body 382 at the first part (for example, one end (upper end)) of the connecting bar 390, and is rotatably connected to the first part (for example, one end (upper end)) of the first cam 361 at the second part (for example, the other end (lower end)) of the connecting bar 390. Thereby, the connecting bar 390 constitutes a link between the locking body 382 and the first cam 361.

[0060] As shown in FIGS. 7 and 8, the connecting bars 370 and 390 are composed of a plurality of parts. Specifically, · In Embodiment 1 of the connecting bar 370 shown in FIG. 7(a), the connecting bar 370 is composed of a bar body 400, an end bar 401, and an appropriate number of fasteners 404 (in addition to bolts, washers and spring washers may also be used as required, the same applies hereinafter). · In Embodiment 2 of the connecting bar 370 shown in FIG. 7(b), the connecting bar 370 is composed of a bar body 400, an end bar 401, an appropriate number of fasteners 404, and a plurality of shims 405. · In Embodiment 3 of the connecting bar 370 shown in FIG. 7(c), the connecting bar 370 is composed of a bar body 400, end bars 401 and 402, and an appropriate number of fasteners 404. · In Embodiment 1 of the connecting bar 390 shown in FIG. 8(a), the connecting bar 390 is composed of a bar body 400, an end bar 401, a reinforcing bar 403, and an appropriate number of fasteners 404. · In Embodiment 2 of the connecting bar 390 shown in FIG. 8(b), the connecting bar 390 is composed of a bar body 400, an end bar 401, a reinforcing bar 403, an appropriate number of fasteners 404, and a plurality of shims 405. · In Embodiment 3 of the connecting bar 390 shown in FIG. 8(c), the connecting bar 390 is composed of a bar body 400, end bars 401 and 402, a reinforcing bar 403, and an appropriate number of fasteners 404.

[0061] As shown in FIG. 9, a bar material is used as the bar body 400. As shown in FIG. 9(a), the bar material is a straight and long plate-shaped, flat bar (flat bar). The bar material has one end (the lower end in the figure) and the other end (the upper end in the figure) in the longitudinal direction. The bar material has a length (total length) of, for example, about 200 mm or more and 800 mm or less (as an example, 500 mm). However, when the height positions of the first cam 361 and the second cam 363 are near the door hanger 311 of the cage door 31 or near the center in the height direction of the cage door 31, it is necessary to correspond to the appropriate length, and it may be about 100 mm or about 1500 mm. The bar material has a width (total width) of, for example, about 10 mm or more and 30 mm or less (as an example, 20 mm). The bar material has a thickness of, for example, about 1.5 mm or more and 5 mm or less (as an example, 3 mm). The bar material is, for example, a metal member made of iron, steel, stainless steel or aluminum as a material. Alternatively, the bar material may be a member made of hard resin.

[0062] The other end is provided with a connection point 400a and is rotatably connected to other mechanical elements. The connection point 400a is, for example, a bush mounted in a through hole formed at the other end. A pin as a rotating shaft is inserted into the bush.

[0063] The bar material (and the bar body 400 using this, hereinafter the same) is provided with a thin-walled portion 400b. The thin-walled portion 400b is formed along a direction (as an example, an orthogonal direction) intersecting the longitudinal direction of the bar material. The thin-walled portion 400b is formed at at least one location in the longitudinal direction of the bar material. Thereby, as shown in FIGS. 9(b) and (c), the bar material can be partially folded at the location of the thin-walled portion 400b. Note that "folding" means folding and causing fatigue fracture at that location and separating a part from the main body part. It is also called "breaking".

[0064] The thin-walled part 400b is formed at a plurality of locations in the longitudinal direction of the bar material. More specifically, the thin-walled parts 400b are formed at equal intervals at a plurality of locations in the longitudinal direction of the bar material. The thin-walled part 400b is formed at a pitch P of about 20 mm or more and 50 mm or less (for example, 30 mm). The thin-walled part 400b is formed at about 5 or more and 15 or less locations (for example, 11 locations).

[0065] The thin-walled part 400b is formed on one surface (for example, the surface) of the bar material. The thin-walled part 400b has a depth D of about 50 ± 10% of the thickness of the bar material (for example, 47%). The thin-walled part 400b is formed across the entire width of the bar material. The thin-walled part 400b is a groove. More specifically, the thin-walled part 400b is a groove having a V-shaped cross section. The groove is formed at an angle of about 40 degrees or more and 70 degrees or less (for example, 53 degrees).

[0066] The bar material includes a long hole 400c. The long hole 400c is formed along the longitudinal direction of the bar material. The long hole 400c is a straight and long hole along the longitudinal direction of the bar material. The long hole 400c is a hole that opens through the front and back surfaces of the bar material. For this reason, the bar material includes a pair of parallel divided parts in the long hole formation region in the longitudinal direction of the bar material.

[0067] The long hole 400c has a length (total length) L of about 50% or more and 90% or less of the length (total length) of the bar material (for example, 70%). The long hole 400c is formed closer to one end of the bar material so that one end in the longitudinal direction of the long hole 400c is close to one end of the bar material. For this reason, one end of the bar material becomes a closed end portion 400d where the long hole 400c does not reach the edge of the bar material. However, when a part of the bar material is folded, one end of the bar material becomes an open end portion 400e where the long hole 400c reaches the edge of the bar material. A predetermined region in the longitudinal direction of the bar material including the other end of the bar material is a long hole non-formation region.

[0068] The thin-walled portion 400b is formed in the elongated hole forming region in the longitudinal direction of the bar material. Therefore, the thin-walled portion 400b is formed in a pair of parallel divided portions. The thin-walled portion 400b is not formed in the non-elongated hole forming region. However, this is not essential.

[0069] The elongated hole 400c has a width (total width) W of about 25% or more and 60% or less of the width (total width) of the bar material (for example, 30% as an example). The elongated hole 400c is formed such that the center line in the width direction of the elongated hole 400c coincides with the center line in the width direction of the bar material.

[0070] As shown in Fig. 10(a), the end bar 401 is a straight, long plate-shaped, flat bar (flat bar). The end bar 401 has one end (the lower end in the figure) and the other end (the upper end in the figure) in the longitudinal direction. The end bar 401 has the same width (total width) as the width (total width) of the bar body 400. The end bar 401 is, for example, a metal member made of iron, steel, stainless steel, or aluminum as a material. Alternatively, the end bar 401 may be a member made of a hard resin.

[0071] One end is provided with a connection point 401a and is rotatably connected to other mechanical elements. The connection point 401a is, for example, a bush mounted in a through hole formed at one end. A pin serving as a rotating shaft is inserted into the bush.

[0072] The end bar 401 is provided with fastening points 401b. The fastening points 401b are provided at at least two locations in the longitudinal direction of the end bar 401. The fastening point 401b is, for example, a female screw into which the bolt of the fastener 404 is screwed. In this case, the end bar 401 is a plate nut.

[0073] Although not shown, the end bar 402 also has the same configuration as the end bar 401. However, as shown in Figs. 7(c) and 8(c), the end bar 402 has a shape in which a portion in the middle is appropriately bent and one end is offset with respect to the other end. This offset shape is also applicable to the end bar 401.

[0074] As shown in FIGS. 11 and 12, the bar body 400 and the end bar 401 are joined by at least two fasteners 404. The fastener 404 fastens the bar body 400 and the end bar 401 at a location passing through the elongated hole 400c of the bar body 400. When the fastening point 401b of the end bar 401 is a female thread, the bolt of the fastener 404 passes through the elongated hole 400c and is screwed into the female thread. In addition, if necessary, a plurality of shims 405 may be inserted between the bar body 400 and the end bar 401 for adjustment.

[0075] As shown in FIG. 10(b), the reinforcing bar 403 is straight, long, plate-shaped, and a flat bar (flat bar). The reinforcing bar 403 has one end (the lower end in the figure) and the other end (the upper end in the figure) in the longitudinal direction. The reinforcing bar 403 has the same width (overall width) as the width (overall width) of the bar body 400. The reinforcing bar 403 has a thickness (for example, 94%) of about 60% or more of the thickness of the bar body 400. The reinforcing bar 403 is, for example, a metal member made of iron, steel, stainless steel, or aluminum. Alternatively, the reinforcing bar 403 may be a member made of hard resin.

[0076] The reinforcing bar 403 is provided with fastening points 403a. The fastening points 403a are provided at a plurality of locations in the longitudinal direction of the reinforcing bar 403. More specifically, the fastening points 403a are provided at equal intervals at a plurality of locations in the longitudinal direction of the reinforcing bar 403. The fastening points 403a are provided at a pitch p of about 20 mm or more and 100 mm or less (for example, 30 mm). The pitch p of the fastening points 403a in the longitudinal direction of the reinforcing bar 403 coincides with the pitch P of the thin-walled portion 400b in the longitudinal direction of the bar body 400. The fastening points 403a are provided at about 3 or more and 8 or less locations (for example, 6 locations). The fastening point 403a is, for example, a female thread into which the bolt of the fastener 404 is screwed. In this case, the reinforcing bar 403 is a plate nut.

[0077] As shown in FIG. 12, the reinforcing bar 403 is coupled to the bar body 400 so as to be attached to the thin-wall portion forming region of the bar body 400 (the portion protruding from the end bar 401). The reinforcing bar 403 is attached to the surface opposite to the surface on which the thin-wall portion 400b is formed (for example, the back surface) among the two opposing surfaces of the bar body 400. The reinforcing bar 403 is attached to the bar body 400 such that both side edges in the width direction of the reinforcing bar 403 coincide with both side edges in the width direction of the bar body 400. Note that being attached means that a certain range in the longitudinal direction abuts.

[0078] The bar body 400 and the reinforcing bar 403 are coupled by at least two fasteners 404. The fastener 404 fastens the bar body 400 and the reinforcing bar 403 at a location passing through the long hole 400c of the bar body 400. When the fastening point 403a of the reinforcing bar 403 is a female screw, the bolt of the fastener 404 passes through the long hole 400c and is screwed into the female screw. At this time, it is preferable that the location of the thin-wall portion 400b of the bar body 400 and the location of the fastening point 403a of the reinforcing bar 403 overlap. In this case, the fastener 404 fastens the bar body 400 at the location of the thin-wall portion 400b, and the head of the bolt of the fastener 404 (or the washer if there is a washer) is attached onto the thin-wall portion 400b.

[0079] The configuration of the elevator 1 according to this embodiment is as described above. Next, the operations of the landing door engagement device 36, the door lock device 38 of the car door 31, and the door lock device 28 of the landing door 23 are the same as those in the prior art, and thus will be briefly described.

[0080] As shown in FIGS. 5 and 6, a first cam 361 as a first engaging body engages with a first roller 27A as a first engaged body during the opening operation of the cage door 31. A second cam 363 as a second engaging body switches from a first state (FIG. 5) to a second state (FIG. 6) during the opening operation of the cage door 31, engages with a second roller 27B as a second engaged body, and clamps the rollers 27A and 27B together with the first cam 361. Thereby, the landing door 23 performs an opening operation without generating lateral vibration as the cage door 31 opens.

[0081] Further, when the first cam 361 engages with the first roller 27A, the first cam 361 receives a reaction force from the first roller 27A and switches from the first state (FIG. 5) to the second state (FIG. 6), and switches the lock body 382 from the locked state (FIG. 5) to the unlocked state (FIG. 6). Thereby, the cage door 31 is unlocked and can be opened.

[0082] Further, when the first cam 361 engages with the first roller 27A, as shown in FIG. 4, the first roller 27A switches from the first state (FIG. 4(a)) to the second state (FIG. 4(b)), and switches the lock body 282 from the locked state (FIG. 4(a)) to the unlocked state (FIG. 4(b)). Thereby, the landing door 23 is unlocked and can be opened.

[0083] As described above, according to the connecting bars 370 and 390 according to the present embodiment, unnecessary portions of the bar material can be folded off at the thin-walled portion 400b, and the length of the bar body 400 can be changed. Since the folding operation can be performed on-site, the length of the bar body 400 can be adjusted on-site. Therefore, according to the connecting bars 370 and 390 according to the present embodiment, it is possible to provide a connecting bar with high versatility that can correspond to various installation positions of the first cam 361 and the second cam 363.

[0084] Further, according to the connecting bars 370 and 390 according to the present embodiment, the thin-walled portions 400b are formed at a plurality of positions in the longitudinal direction of the bar material. Therefore, according to the connecting bars 370 and 390 according to the present embodiment, fine length adjustment is possible.

[0085] Also, according to the connecting bars 370 and 390 according to the present embodiment, the thin portion 400b has a depth of 50 ± 10% of the thickness of the bar material. If the depth is too deep, the strength of the bar body 400 may decrease, and the function as the connecting bars 370 and 390 may be impaired. However, if the depth is too shallow, it may become impossible to cleanly break off the bar material, or a large force may be required to break it off. According to the connecting bars 370 and 390 according to the present embodiment, a suitable bar body 400 can be obtained in consideration of both balances.

[0086] Also, according to the connecting bars 370 and 390 according to the present embodiment, the bar material is provided with a long hole 400c formed along the longitudinal direction of the bar material, and the thin portion 400b is formed in the long hole forming region in the longitudinal direction of the bar material. Since there is the long hole 400c, the break-off length becomes shorter. Moreover, since a pair of divided portions of the bar material exist on both sides of the long hole 400c, the strength of the bar body 400 is not impaired. Therefore, according to the connecting bars 370 and 390 according to the present embodiment, while maintaining the strength of the bar body 400, it can be broken off with a relatively small force compared to the case where there is no long hole, and the length adjustment can be easily performed.

[0087] Also, according to the connecting bar 390 according to the present embodiment, the bar body 400 is reinforced by the reinforcing bar 403, and the strength is improved. When the door lock device 38 of the cage door 31 operates to be in the unlocked state, a compressive load acts on the connecting bar 390. Then, since the connecting bar 390 has the thin portion 400b, there is a risk of buckling or breakage. However, by adding the reinforcing bar 403, the bar body 400 is reinforced. Therefore, according to the connecting bar 390 according to the present embodiment, the risk of buckling or breakage can be eliminated. Regarding the connecting bar 370, a tensile load acts instead of a compressive load. Therefore, the reinforcing bar 403 is not necessarily required. However, it goes without saying that the reinforcing bar 403 can also be applied to the connecting bar 370.

[0088] In addition, if the reinforcing bar 403 is provided, when the bar material is accidentally cut short on site or when it is necessary to change the positions of the first cam 361 and the second cam 363 after disassembly, the reinforcing bar 403 can be used for reconnection to lengthen the length of the connecting bar 390. Therefore, there is also an effect that it is not necessary to re-arrange the parts.

[0089] Further, according to the connecting bar 390 according to the present embodiment, the reinforcing bar 403 is applied to the surface of the bar body 400 opposite to the surface on which the thin-walled portion 400b is formed among the two opposing surfaces of the bar body 400. Since the bar body 400 has the thin-walled portion 400b on one surface, it is inevitably likely to buckle on one surface side. The reinforcing bar 403 serves as a resistance against this. Therefore, according to the connecting bar 390 according to the present embodiment, the risk of buckling and breakage can be eliminated.

[0090] Further, according to the connecting bar 390 according to the present embodiment, the reinforcing bar 403 has a length equal to or greater than the range of the thin-walled portion forming region where a part of the bar material has been disassembled and shortened. Therefore, according to the connecting bar 390 according to the present embodiment, the weak portions can be comprehensively reinforced.

[0091] Further, according to the connecting bar 390 according to the present embodiment, the pitch p of the fastening points 403a in the longitudinal direction of the reinforcing bar 403 coincides with the pitch P of the thin-walled portions 400b in the longitudinal direction of the bar body 400. Therefore, according to the connecting bar 390 according to the present embodiment, the portions of the thin-walled portions 400b of the bar body 400 and the portions of the fastening points 403a of the reinforcing bar 403 are overlapped, and the fastener 404 fastens the bar body 400 at the locations of the thin-walled portions 400b, so that the thin-walled portions 400b, which are particularly vulnerable to buckling, can be reinforced.

[0092] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

[0093] In the above-described embodiment, the first cam 361 and the second cam 363 as engaging members are each provided so as to be independently translatable, and connecting bars 390 and 370 are applied to each of them. However, the present invention is not limited to this. Either one of the engaging members may be fixed, and a structure in which a connecting bar is not applied to this engaging member may be used. For example, when the door lock device 38 of the car door 31 is not provided, the first cam 361 becomes fixed and the connecting bar 390 becomes unnecessary. When the clamping function is not provided in the landing door engaging device 36, the second cam 363 becomes fixed and the connecting bar 370 becomes unnecessary.

[0094] Also, in the above-described embodiment, the novel structure of the connecting bar according to the present invention is applied to the connecting bar 370 of the landing door engaging device 36 and the connecting bar 390 of the door lock device 38 of the car door 31. However, the present invention is not limited to this. The novel structure of the connecting bar according to the present invention may be applied to the connecting bar of the door lock device of the landing door.

[0095] Also, in the above-described embodiment, the connecting bar 370 is directly connected to the second cam 363, and the connecting bar 390 is directly connected to the first cam 361. However, the present invention is not limited to this. The connecting bar may be connected to a parallel link.

[0096] Also, in the above-described embodiment, the connecting bars 370 and 390 use, as the bar body 400, a member obtained by folding a part of the bar material. However, the present invention is not limited to this. The connecting bar may use the bar material as it is (FIG. 9(a)) without folding a part of the bar material as the bar body.

[0097] Also, in the above-described embodiment, the bar body 400 (bar material) is a flat member. However, the present invention is not limited to this. The bar body (bar material) may be a non-flat member, for example, a member having a circular or elliptical cross section (round bar or elliptical bar).

[0098] Further, in the above embodiment, the thin portion 400b is a groove having a V-shaped cross section. However, the present invention is not limited to this. The groove may be a groove having a shape other than a V-shaped cross section, such as a U-shaped cross section. Also, the thin portion may not be a groove. For example, a plurality of concave portions may be arranged in a line with an interval.

[0099] Further, in the above embodiment, the thin portion 400b is formed on one surface of the bar body 400 (bar material). However, the thin portion may be formed on the opposite surface of the bar body (bar material) (that is, on both surfaces).

[0100] Further, in the above embodiment, the thin portion 400b is formed along a direction perpendicular to the longitudinal direction of the bar body 400 (bar material). However, the present invention is not limited to this. The thin portion may be formed along a direction inclined obliquely with respect to the direction perpendicular to the longitudinal direction of the bar body (bar material).

[0101] Further, in the above embodiment, the thin portion 400b is formed over the entire width of the bar body 400 (bar material). However, the present invention is not limited to this. The thin portion may not reach the side edge of the bar body (bar material), for example, and the side edge portion of the bar body (bar material) may be a non-thin-portion-forming portion. Also, the thin portion may not reach the side edge of the long hole, for example, and the side edge portion of the long hole may be a non-thin-portion-forming portion.

[0102] Further, in the above embodiment, the reinforcing bar 403 is attached to the opposite surface of the bar body 400 from the surface on which the thin portion 400b is formed among the two opposing surfaces of the bar body 400. However, the present invention is not limited to this. The reinforcing bar may be attached to the surface on which the thin portion is formed. Alternatively, two reinforcing bars may be used and attached to both surfaces so as to sandwich the bar body.

[0103] In the above-described embodiment, the fastening means for the bar body 400 and the end bars 401 and 402, and the fastening means for the bar body 400 and the reinforcing bar 403 are a combination of a bolt and a female screw. However, the present invention is not limited to this. For example, instead of a female screw, through holes may be provided in the end bars or the reinforcing bar, and a fastening means of a combination of a bolt and a nut may be used. Alternatively, another known fastening means such as a rivet may be used.

[0104] In the above-described embodiment, the door devices 30 and 22 are of the center open type (2CO) with one door on each of the left and right sides. However, the present invention is not limited to this. Needless to say, the present invention can also be applied to a side open type (2S) door device with two doors, a center open type (4CO) door device with two doors on each of the left and right sides, and a side open type (1S) door device with one door.
