To provide an engagement device etc. that can normally engage a car-side engagement part and a building-side engagement part even if the car shakes due to an earthquake or the like while the car is traveling. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides an engagement device that includes a building-side engagement part that engages with a car-side engagement part provided on a car, in order to open and close a building-side door in conjunction with the car door when the car, which is moving up and down in an elevator shaft provided in a building, stops at an entrance / exit position, and a protective cover that is provided on top of the building-side engagement part and guides the car-side engagement part so that it engages with the building-side engagement part as the car moves.In this case, it is possible to provide an engagement device that can normally engage the car-side engagement part and the building-side engagement part even if the car shakes due to an earthquake or the like while the car is traveling.

[0007] Here, for example, the building-side engagement portion includes a pair of engagement rollers arranged side by side in a direction intersecting the direction in which the elevator car ascends and descends, and the protective cover is provided to cover the top of the pair of engagement rollers. In this case, even if the elevator car shakes due to an earthquake or the like while it is traveling, damage to the engagement rollers can be prevented. Furthermore, for example, the car-side engaging portion includes a pair of side walls that sandwich the pair of engaging rollers, and the protective cover is provided so as to fit within a width that is smaller than the width of the inner sides of the pair of side walls. In this case, the protective cover can guide the car-side engaging portion to the normal position. Furthermore, for example, the protective cover is provided at a position that guides the pair of engaging rollers so that they enter between the pair of side walls. In this case, the protective cover can guide the car-side engaging portion to the normal position where it enters between the side walls. Furthermore, for example, the protective cover is made of two plate-like members arranged so that the distance between them increases from top to bottom. In this case, the protective cover can be easily produced. For example, a protective cover is further provided below the building-side engaging portion. In this case, the car-side engaging portion and the building-side engaging portion can be properly engaged with each other even when the car is rising. Furthermore, for example, the protective cover provided on the lower part of the building-side engaging part is made up of two plate-shaped members arranged so that they are spaced apart from each other as they go from bottom to top. In this case, the protective cover can be easily produced.

[0008] The present invention also provides a car that moves up and down in a hoistway provided in a building, the car having a car-side engaging part that engages with a building-side engaging part for opening and closing a building door in conjunction with the car door when the car stops at an entrance / exit position, and that has cutouts at the top and bottom ends of a pair of rectangular side walls extending in the vertical direction.In this case, it is possible to provide a car that can normally engage with the car-side engaging part and the building-side engaging part.

[0009] Here, for example, the notches are provided at two corners of a rectangular shape that face the building. In this case, even if the car-side engaging portion and the building-side engaging portion come into contact with each other, the impact can be alleviated. Furthermore, for example, the building-side engaging portion includes a pair of engaging rollers arranged side by side in a direction intersecting the direction in which the car ascends and descends, and the notch is arranged so that when the car ascends or descends, it strikes the pair of engaging rollers at an angle. In this case, damage to the engaging rollers can be prevented.

[0010] Furthermore, the present invention provides an elevator comprising a car that moves up and down in a hoistway provided in a building, and an engagement system that opens and closes a building door in conjunction with the car door when the car stops at an entrance / exit position, the engagement system comprising a car-side engagement part provided in the car, a building-side engagement part provided in the building and engaging with the car-side engagement part, and a protective cover provided above the building-side engagement part and guiding the building-side engagement part to engage with the car-side engagement part as the car moves. In this case, even if the car shakes due to an earthquake or the like while it is traveling, the car-side engagement part and the building-side engagement part can be normally engaged.

[0011] Here, for example, the car-side engaging portion engages with the building-side engaging portion and has notches at the top and bottom ends of a pair of rectangular side walls extending in the vertical direction, so that even if the car-side engaging portion and the building-side engaging portion come into contact with each other, the impact can be alleviated. [Effects of the Invention]

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. <Overall explanation of Elevator 100>

[0015] 1 and 2 are diagrams showing an example of the configuration of an elevator 100 according to this embodiment. Of these, Fig. 1 is a diagram of the elevator 100 as viewed from above. Fig. 2 is a diagram of the elevator 100 as viewed from the side, that is, as viewed from the direction II in Fig. 1. The elevator 100 mainly comprises a hoist 3 that winds up the main rope 17, a car 4 that moves up and down within an elevator shaft 1 provided in a building, a counterweight 5 suspended from the car 4 via the main rope 17, a speed governor 6 that detects the ascending and descending speed of the car 4, and a control panel 7 that controls the operation of the elevator 100.

[0016] The hoist 3 is installed on a hoist beam 3A installed at the top of the hoistway 1. A main rope 17 is wound around the hoist 3. Both ends of the main rope 17 are connected to rope ends 18A, 18B installed at the top of the hoistway 1. One end of the main rope 17 is connected to the car 4 via an under-car pulley 9, and the other end is connected to a counterweight 5. When the hoist 3 starts and the main rope 17 runs, the car 4 moves up and down within the hoistway 1. The counterweight 5 moves up and down in opposite directions to the car 4. By balancing with the car 4 using the counterweight 5, the unbalance caused by the car 4 is reduced, and the car 4 can be moved up and down with little power.

[0017] The car 4 is supported by a pair of guide rails 2A, 2B arranged in the lifting direction within the elevator shaft 1 so as to be movable in the lifting direction. The pair of guide rails 2A, 2B are supported by rail brackets 20A, 20B fixed to the wall surface 1A of the elevator shaft 1. The car 4 is provided with a car door 47. The car door 47 faces an entrance hall 12 provided at the landing where the car 4 stops, through which people and objects enter and exit the car 4. In addition, a hatch door 48 is provided in the entrance hall 12, which opens and closes in conjunction with the car door 47. The car 4 is also provided with an operation panel 41, on which buttons are arranged for passengers to open and close the doors and specify the destination floor.

[0018] Counterweight 5 is supported so as to be able to move up and down in hoistway 1 by a pair of guide rails 2C, 2D arranged in the lifting direction within hoistway 1. The pair of guide rails 2C, 2D are supported by rail brackets 20B, 20C fixed to wall surface 1A of hoistway 1.

[0019] An upper governor pulley 6A, a governor rope 16, and a lower governor pulley 15 are connected to the governor 6. The upper governor pulley 6A is disposed near the hoist beam 3A at the top of the hoistway 1. The governor rope 16 is wound around the upper governor pulley 6A. The lower governor pulley 15 is disposed below the upper governor pulley 6A in the pit of the hoistway 1. The governor rope 16 is wound around the lower governor pulley 15. The car 4 has a connecting part that connects to the governor rope 16, and the governor rope 16 is wound up as the car 4 rises and falls. As a result, the rising and falling speed of the car 4 is detected by the governor 6 via the governor rope 16. When the rising and falling speed of the car 4 exceeds a predetermined speed, the governor 6 activates the safety device 30. This causes the car 4 to stop.

[0020] The control panel 7 controls the operation of the hoisting machine 3, thereby controlling the up and down movement of the car 4. The control panel 7 is connected to the car 4 by a tail cord 21. The tail cord 21 is suspended from the tail cord support 8 and is an electric wire that connects the control panel 7 to the car 4, and supplies electricity and transmits control signals from the control panel 7 to the car 4.

[0021] The elevator 100 also includes a shielding plate 10 and a position detector 11. The position detector 11 is attached to a position detector bracket 11A provided on the top of the car 4. The position detector 11 detects the absolute position of the car 4 within the elevator shaft 1. The position detector 11 is, for example, a photoelectric sensor that detects the position of a hole opened in a shielding plate 10 attached to a shielding plate bracket 10A provided within the elevator shaft 1. The position detector 11 detects the current height position of the car 4 within the elevator shaft 1 and the floor on which it is stopped, based on the absolute position detected by the photoelectric sensor (for example, the height from the bottom of the elevator shaft 1) and initial value information. The position detector 11 transmits the detected height position information of the car 4 to the control panel 7 via a tail cord 21.

[0022] Furthermore, the elevator 100 is equipped with a shock absorber 22. The shock absorber 22 is disposed below the car 4 and the counterweight 5. The shock absorber 22 is a device that absorbs the impact of a fall when the car 4 or the counterweight 5 falls due to an abnormality.

[0023] FIG. 3 is a diagram showing the elevator 100 of this embodiment when it stops at a predetermined floor. In this state, the car door 47 on the car 4 and the hatch door 48 on the entrance hall 12 of the elevator 100 are positioned opposite each other. In addition, the height of the car floor 49 of the car 4 is the same as the floor of the entrance hall 12. However, due to some cause such as a power outage, the car 4 may stop deviating from the entrance hall 12. In this case, a gap will be created between the car 4 and the entrance hall 12, so an apron 32 is attached to the bottom of the car 4 to prevent passengers 101 from falling into the hoistway 1. In addition, a toe guard 46 is provided in the entrance hall 12 for the same purpose.

[0024] The elevator 100 is also provided with a car sill 44 that supports the car door 47 and guides the lower end of the car door 47 so that it can move in the opening and closing direction, and a hatch sill 45 that supports the hatch door 48 and guides the lower end of the hatch door 48 so that it can move in the opening and closing direction. Furthermore, the elevator 100 is provided with an engagement system 50 that opens and closes a building-side hatch door 48 in conjunction with the car door 47 of the car 4 when the car 4 stops at an entrance / exit position. This engagement system 50 includes a car-side engagement unit 51 provided on the car 4 and a building-side engagement unit 52 that is provided on the building and engages with the car-side engagement unit 51. As will be described in detail later, the building-side engagement unit 52 engages with the car-side engagement unit 51 provided on the car 4 in order to open and close the building-side hatch door 48 in conjunction with the car door 47 of the car 4 when the car 4, which is moving up and down in the elevator shaft 1 provided in the building, stops at an entrance / exit position.

[0025] 4(a) to 4(c) are diagrams illustrating the car-side engaging portion 51. FIG. Figures 4(b) and 4(c) illustrate the portion of the car 4 that is surrounded by a dotted line in Figure 4(a). Figure 4(b) is a view of the area around the car-side engaging portion 51 from the same direction as Figure 4(a). Figure 4(c) is a view of the area around the car-side engaging portion 51 from the direction IVc in Figure 4(a).

[0026] 4(b) and 4(c) can also be said to be diagrams showing the opening and closing mechanism of the car door 47 of the car 4. Here, the above-mentioned car door 47 and car sill 44 are illustrated. A door motor 511 is provided on the top of the car door 47 as a power source for opening and closing the door. When the door motor 511 is driven, pulleys 512A and 512B rotate. This rotation then moves a belt 513. Furthermore, as the belt 513 moves, a connecting member 514 moves, and the car door 47 connected to the connecting member 514 opens and closes. Further, the connecting member 514 is provided with a car-side engaging portion 51, which also moves as the car door 47 opens and closes.

[0027] 5(a) to 5(c) are diagrams illustrating the building-side engaging portion 52. FIG. Figures 5(b) and 5(c) show the part of the building enclosed by the dotted line in Figure 5(a), Figure 5(b) is a perspective view of Figure 5(a), and Figure 5(c) is an enlarged view of the upper part of Figure 4(b).

[0028] Figure 5(b) can also be said to be a diagram showing the opening and closing mechanism of the hatch door 48 of the entrance hall 12. Here, the hatch door 48 and hatch sill 45 are shown. Figure 5(b) also shows a jamb 521 that forms the entrance. Furthermore, a pocket 522 is provided above the hatch door 48, and as shown in Figure 5(c), this is where the building-side engagement part 52 is housed.

[0029] 6(a) and 6(b) are diagrams showing the positional relationship between the car-side engaging portion 51 and the building-side engaging portion 52 when the car 4 stops at a predetermined floor. Fig. 6(a) is a diagram of the car-side engagement portion 51 and the building-side engagement portion 52 as viewed from above. Fig. 6(b) is a diagram of the building-side engagement portion 52 as viewed from the direction VIb in Fig. 6(a). As shown in the figure, the car-side engagement portion 51 has a rough U-shape when viewed from above. Alternatively, the car-side engagement portion 51 can be said to have a concave (-) shape when viewed from above. The car-side engagement portion 51 can also be said to have a pair of side walls 51A, 51B. The opening created by this shape faces the building. When the car 4 is about to stop at a predetermined floor, the building-side engagement portion 52 enters and engages with the opening, and in this state, the car 4 stops. When the door motor 511 (see FIG. 4 ) is driven to open or close the car door 47, the car-side engagement portion 51 moves left and right in the figure together with the car door 47. In this case, the building-side engagement portion 52 is engaged with the car-side engagement portion 51, and therefore moves left and right in the figure, similar to the car-side engagement portion 51. Furthermore, since the building-side engaging portion 52 is joined to the hatch door 48, the hatch door 48 also moves left and right in the figure. Ultimately, by driving the door motor 511, the car door 47 and the hatch door 48 move in conjunction with each other left and right in the figure.

[0030] The building-side engagement portion 52 includes two engagement rollers 52A and 52B. As shown in Fig. 6(a), the car-side engagement portion 51 and the building-side engagement portion 52 are brought into an engaged state by accommodating the two engagement rollers 52A and 52B in the opening of the car-side engagement portion 51.

[0031] However, when shaking such as an earthquake occurs, the car 4 sways back and forth and side to side, and the car-side engaging portion 51 may come into contact with the building-side engaging portion 52 in a state displaced from its original position. FIG. 7(a) is a diagram showing a case where the car-side engaging portion 51 comes into contact with the building-side engaging portion 52 in a state where it is displaced from its original position. Among these, the car-side engaging portion 51 indicated by the dotted line indicates the original position of the car-side engaging portion 51. When the car 4 descends in this state, the car-side engaging portion 51 engages with the building-side engaging portion 52 in the normal position. On the other hand, the car-side engagement part 51, indicated by a solid line, has shifted from its original position due to the swinging of the car 4. If the car 4 descends in this state, the lower end of the car-side engagement part 51 will collide with the upper part of the engagement roller 52B of the building-side engagement part 52. If one of the engagement rollers 52A, 52B is damaged by the collision, the car-side engagement part 51 and the building-side engagement part 52 may not be able to engage with each other. In this case, the hatch door 48 cannot be opened, and passengers will be trapped inside.

[0032] Therefore, in this embodiment, this problem is solved by providing a protective cover 53 on the upper part of the engagement rollers 52A and 52B. The car-side engagement portion 51 and the protective cover 53 function as the engagement device of this embodiment.

[0033] FIG. 7(b) is a diagram showing a case where a protective cover 53 according to this embodiment is provided. As shown in the figure, the protective cover 53 is provided on the upper part of the building-side engagement part 52. This protective cover 53 is made up of two plate-like members arranged so that they become more spaced apart as they go from top to bottom. In this case, the protective cover 53 can also be said to be shaped like the Japanese character "V". Alternatively, the protective cover 53 can also be said to be shaped like the Japanese character "^". Furthermore, the building-side engagement part 52 can be said to include engagement rollers 52A and 52B as a pair of movable rollers arranged side by side in a direction intersecting the ascending and descending direction of the car 4, and the protective cover 53 is provided so as to cover the upper parts of the engagement rollers 52A and 52B.

[0034] The protective cover 53 guides the car-side engaging part 51 to engage with the building-side engaging part 52 as the car 4 moves. In other words, even if the car-side engaging part 51 becomes displaced from its original position as shown by the solid line due to the car 4 swinging, when the car 4 descends, the lower end of the car-side engaging part 51 comes into contact with the protective cover 53. Then, guided by the protective cover 53, the car-side engaging part 51 is returned to its original position, and the car-side engaging part 51 engages with the building-side engaging part 52 in the correct position.

[0035] In this case, it can also be said that the car-side engagement portion 51 includes a pair of side walls 51A, 51B that are arranged to sandwich the pair of engagement rollers 52A, 52B, and the protective cover 53 is arranged to fit within a width that is smaller than the inner width of the pair of side walls 51A, 51 B. It can also be said that the protective cover 53 is arranged in a position that guides the pair of engagement rollers 52A, 52B to fit between the pair of side walls 51A, 51B.

[0036] The car-side engaging portion 51 and the building-side engaging portion 52 are protruding portions for engaging with each other. Therefore, when the car 4 shakes due to an earthquake or the like, contact is likely to occur at a position shifted from its original position, and the engaging rollers 52A and 52B in particular are likely to be damaged. By providing the protective cover 53, damage to the engaging rollers 52A and 52B can be prevented, and passengers can be prevented from being trapped inside.

[0037] In the above example, the protective cover 53 is provided on the upper part of the building-side engaging portion 52, but it may also be provided on the lower part of the building-side engaging portion 52. In this case, the protective cover 53 provided on the lower part of the building-side engaging portion 52 has a shape that is vertically symmetrical to the protective cover 53 provided on the upper part, sandwiching the building-side engaging portion 52. In other words, the protective cover 53 provided on the lower part of the building-side engaging portion 52 is made up of two plate-like members that are arranged so that they are spaced apart from each other as they go from bottom to top. In this case, the protective cover 53 can also be said to be shaped like the letter "V."

[0038] Fig. 8 is a view of the car-side engaging portion 51 and the building-side engaging portion 52 when viewed from the VIII direction in Fig. 7(b). Note that, for ease of explanation, the protective cover 53 is not shown here.

[0039] 8 shows a state in which the car-side engaging portion 51 engages with the building-side engaging portion 52 as the car 4 moves from up to down. In this embodiment, the car-side engaging portion 51 engages with the building-side engaging portion 52, and has cutout portions 51K1, 51K2 at the upper and lower ends of a pair of both side walls 51A, 51B that are rectangular and extend in the vertical direction. In this case, it can also be said that the cutout portions 51K1, 51K2 are provided at two corners of the rectangle that are located on the building side.

[0040] The car-side engagement portion 51 shown by dotted lines indicates the original position of the car-side engagement portion 51. On the other hand, the car-side engagement portion 51 shown by solid lines indicates that the car 4 has been displaced from its original position due to swinging. As shown by dotted lines, when the car-side engagement portion 51 is displaced from its original position and the car 4 hits the pair of engagement rollers 52A, 52B as it descends, the cutout portions 51K2 cause the car 4 to hit the pair of engagement rollers 52A, 52B at an angle. As a result, damage to the engagement rollers 52A, 52B can be prevented, and passengers can be prevented from being trapped. When the car 4 hits the pair of engagement rollers 52A, 52B as it ascends, the cutout portions 51K1 cause the car 4 to hit the pair of engagement rollers 52A, 52B at an angle. In short, it can be said that when the car 4 hits the pair of engagement rollers 52A, 52B as it ascends or descends, the cutout portions 51K2 cause the car 4 to hit the pair of engagement rollers 52A, 52B at an angle. Then, the car-side engaging portion 51 is returned to its original position, and the car-side engaging portion 51 engages with the building-side engaging portion 52 in the normal position. By providing the cutout portions 51K1 and 51K2, damage to the engaging rollers 52A and 52B can be prevented, and passengers can be prevented from being trapped inside.

[0041] It should be noted that the car-side engaging part 51 may come into contact not only with the engaging rollers 52A and 52B but also with a protruding part provided on the hoistway 1. This protruding part may be, for example, the head of a bolt. According to the embodiment of FIG. 8, when it comes into contact with such a protruding part, the cutouts 51K1 and 51K2 cause it to come into contact at an angle. Therefore, in this case as well, the car-side engaging part 51 can be returned to its original position.

[0042] Although the present embodiment has been described above, the technical scope of the present invention is not limited to the scope described in the above embodiment. It is clear from the claims that various modifications and improvements to the above embodiment are also included in the technical scope of the present invention. [Explanation of symbols]
