[0037] The rescue structure of the elevator car top and its operation according to each embodiment of the present invention will be described with reference to the accompanying drawings.
[0038] In the following description, the same reference numerals are given to components having the same or similar functions in each embodiment, and repeated description of these components may be omitted.
[0039] [First embodiment]
[0040] [Composition of the rescue structure of the elevator car top]
[0041] Reference Figures 1 to 4 The configuration of the rescue structure for the elevator car top according to the first embodiment of the present invention will be described.
[0042] Figure 1It is a schematic diagram showing the entire elevator car provided with the rescue structure of the elevator car top according to the first embodiment. Figure 2 It is a perspective view showing the rescue structure of the elevator car top according to the first embodiment.
[0043] like Figure 1 As shown, the elevator includes an elevator car 1 and a car top plate 2 located on the top of the car, and the rescue structure of the present embodiment is provided on the car top plate 2 .
[0044] like Figure 2 As shown, the rescue structure of the present embodiment includes a rescue exit cover 4 , a slide guide 5 , a locking mechanism 6 , a safety switch mechanism 7 , and a stopper mechanism 8 as main components.
[0045] Reference Figure 3 and Figure 4 The specific configuration of the above-mentioned main components in the rescue structure of the present embodiment will be described.
[0046] Figure 3 1 and 2. The three views show the rescue structure of the elevator car top according to the first embodiment, wherein (a) is a top view viewed from the car top side, (b) is a front view, and (c) is a view from the right side. Figure 4 It is a diagram showing a state where the rescue exit of the rescue structure on the elevator car roof according to the first embodiment is in an open position. Figure 4 It is a diagram showing a state where the rescue exit of the rescue structure on the elevator car roof according to the first embodiment is in an open position.
[0047] Next, the rescue opening cover 4 in the rescue structure of the elevator car top according to the present embodiment will be described.
[0048] In the rescue structure of the elevator car top of this embodiment, Figure 1 and Figure 4 As shown, an opening is formed at the rear side of the car roof panel to form a rescue exit 3, and the rescue exit 3 is formed to a size that a person can enter and exit, so that rescue or maintenance can be performed through the rescue exit. The rescue exit cover 4 can slide between a closed position to close the rescue exit 3 and an open position to open the rescue exit 3. Thus, the rescue exit 3 can be opened only by sliding the rescue exit cover 4, and the rescue exit can be exposed in a small space on the top of the car roof.
[0049] In the rescue structure of the elevator car top of this embodiment, the sliding direction of the rescue exit cover plate 4 includes an opening direction and a closing direction. Figure 4 As shown, the opening direction of the rescue exit cover 4 is from the rear side to the front side, and correspondingly, the closing direction (i.e., the reset direction) of the rescue exit cover 4 is from the front side to the rear side. At this time, the rear side is the upstream side in the opening direction (the downstream side in the closing direction), and the front side is the downstream side in the opening direction (the upstream side in the closing direction).
[0050] like Figures 1 to 4 As shown, a handle 41 is provided at a predetermined position on the upper surface of the rescue exit cover 4 , and is used by an operator to apply a force to the rescue exit cover 4 to open or close the rescue exit cover 4 .
[0051] Next, the slide guide portion 5 in the rescue structure of the elevator car top according to the present embodiment will be described.
[0052] like Figure 3 and Figure 4 As shown, in the rescue structure of the elevator car top of this embodiment, the sliding guide part 5 is respectively provided on the car top board 2 along the front-back direction on the left and right sides of the rescue exit 3 to guide the sliding of the rescue exit cover plate 3. Here, the sliding guide part 5 limits the movement trajectory of the rescue exit cover plate 3 when sliding to the front-back direction, for example, formed as a slide groove. And, as an example, the slide groove 5 can adopt a C-shaped or U-shaped groove with a width in the range of 50 to 100 mm.
[0053] In the rescue structure of the elevator car top of the present embodiment, sliders 51 are respectively provided on the left and right sides of the lower surface of the rescue exit cover plate 4. By providing the rescue exit cover plate 4, the rescue exit cover plate 4 can slide smoothly in the chute 5. Figure 3 The figure shows that a slider 51 is provided at each of the left and right sides of the lower surface of the rescue exit cover plate 4 at both ends in the front-rear direction, and a total of four sliders 51 are provided. However, the number and position of the sliders 51 are not limited to Figure 3 For example, only one slider 51 may be provided at the center of each of the left and right sides of the lower surface of the rescue exit cover 4 in the front-to-back direction, or more than three sliders 51 may be provided evenly in the front-to-back direction of each of the left and right sides of the lower surface.
[0054] Next, the locking mechanism 6 in the rescue structure of the elevator car top according to the present embodiment will be described.
[0055] like Figure 3 and Figure 4 As shown, in the rescue structure of the elevator car top of this embodiment, the locking mechanism 6 is fixed to the car top plate 2. When the rescue exit cover plate 4 is in the closed position, the locking mechanism 6 locks the rescue exit cover plate 4 relative to the car top plate 2.
[0056] Specifically, if Figure 3As shown, the locking mechanism 6 is provided on the car top board near the rear side (upstream side in the opening direction) of the rescue exit cover plate 4 when closed, and includes a locking member 61 fixed to the car top board 2 and a locking plate 62 that can rotate synchronously with the locking member 61. When the rescue exit cover plate 4 is in the closed position, the locking plate 62 presses the upper surface of the rescue exit cover plate 4 toward the car top board 2, thereby locking the rescue exit cover plate 4 relative to the car top board 2. Moreover, the locking member 61 is configured to be able to be operated from the lower surface side of the car top board 2 facing the inside of the car to release the lock of the rescue exit cover plate 4 relative to the car top board 2, and the locking plate 62 is configured to be able to be operated from the upper surface side of the car top board 2 facing the outside of the car to release the lock of the rescue exit cover plate 4 relative to the car top board 2. Therefore, the locking mechanism 6 can be unlocked from both inside and outside the car, so that both rescue from outside the car and self-rescue from inside the car can be achieved.
[0057] Here, as an example of the lock member 61, a triangular lock for elevators with a triangular lock core section can be used, but it is not limited to this. As long as it is configured to be unlocked by a key, for example, a quadrilateral lock with a quadrilateral lock core section can also be used.
[0058] In the case where the lock member 61 is a triangular lock, in the above-mentioned locking mechanism 6, the lock member 61 is rotated by unlocking it with a triangular key from inside the car, driving the lock plate 62 to rotate, and when the lock plate 62 rotates to a position where it is separated from the upper surface of the rescue exit cover plate 4, the pressing of the lock plate 62 on the upper surface of the rescue exit cover plate 4, that is, the locking of the rescue exit cover plate 4 by the locking mechanism 6 is released. At the same time, since the lock plate 62 is formed to be operable from the upper surface side of the car top plate 2, the lock plate 62 can be rotated to a position where it is separated from the upper surface of the rescue exit cover plate 4 by directly applying a force to rotate the lock plate 62 from the outside of the car as the upper side of the car top, and at this time, the pressing of the lock plate 62 on the upper surface of the rescue exit cover plate 4, that is, the locking of the rescue exit cover plate 4 by the locking mechanism 6 is released. Therefore, the locking mechanism 6 of this embodiment can be unlocked from both inside and outside the car as described above.
[0059] In addition, if Figure 2 and Figure 3 As shown, a locking mechanism protection cover 63 is provided for the locking mechanism 6, thereby protecting the locking mechanism 6 and preventing water from entering the locking mechanism 6 in the event of a water leak or the like.
[0060] Next, the safety switch mechanism 7 in the rescue structure of the elevator car top according to the present embodiment will be described.
[0061] In the rescue structure of the elevator car top of the present embodiment, when the rescue exit cover 4 is in the closed position, the safety switch mechanism 7 is in the on state, and the elevator can operate normally. As the rescue exit cover 4 starts to slide along the slide groove 5 from the closed position, the safety switch mechanism 7 becomes disconnected, causing the elevator to stop operating.
[0062] Specifically, if Figure 3 As shown, the safety switch mechanism 7 includes, for example, a switch body 71 disposed on the car top plate 2, and a switch contact 72 disposed on the rescue exit cover plate 4. When the rescue exit cover plate 4 is in the closed position, the switch body 71 and the switch contact 72 are in the connected state, and the elevator can operate normally. As the rescue exit cover plate 4 starts to slide along the slide groove 5 from the closed position, the switch contact 72 is carried by the rescue exit cover plate 4 to move in the direction away from the switch body 71, and the switch body 71 and the switch contact 72 are separated and become disconnected, so that the elevator stops operating. Therefore, the safety switch mechanism 7 stops the elevator as the rescue exit cover plate 4 starts to slide, thereby preventing the elevator from accidentally operating during rescue and causing an accident.
[0063] In addition, if Figure 2 and Figure 3 As shown, a safety switch mechanism protection cover 73 is provided for the safety switch mechanism 7. This can protect the safety switch mechanism 7, and can prevent water from entering the safety switch mechanism 7 in the event of a water leak, for example.
[0064] Next, the stopper mechanism 8 in the rescue structure of the elevator car top according to the present embodiment will be described.
[0065] In the rescue structure of the elevator car roof of the present embodiment, the stopper mechanism 8 includes a movable portion 81 provided on the rescue exit cover 4 and a fixed portion 82 provided on the chute 5 corresponding to the fixed portion.
[0066] The stopper mechanism 8 is configured such that when the rescue exit cover plate 4 is in the closed position, the movable portion 81 is engaged with the fixed portion 82, thereby engaging the rescue exit cover plate 4 provided with the movable portion 81 with the chute 5 provided with the fixed portion 82, that is, fastening the rescue exit cover plate 4 to the car top plate 2 (provided with the chute 5). At this time, the stopper mechanism 8 functions as a fastening member fastening the rescue exit cover plate 4 to the car top plate 2.
[0067] The stop mechanism 8 is constructed such that as the rescue exit cover 4 starts to slide along the slide groove 5 from the closed position, the movable part 81 is moved by the rescue exit cover 4 in the direction away from the fixed part 82, the movable part 81 separates from the fixed part 82, and the rescue exit cover 4 can continue to slide along the slide groove 5.
[0068] The stopping mechanism 8 is constructed so that when the rescue exit cover 4 is reset from the open position to the closed position, after the rescue exit cover 4 slides to the position where the movable portion 81 engages with the fixed portion 82, the engagement between the movable portion 81 and the fixed portion 82 prevents the rescue exit cover 4 from sliding further toward the closed position. At this time, the stopping mechanism 8 can act as a limiting component for limiting the position of the rescue exit cover 4, and can prevent the switch contacts 72 installed on the rescue exit cover 4 from colliding with the switch body 71, and the rescue exit cover 4 from colliding with the locking mechanism 6.
[0069] like Figure 3 As shown, the movable part 81 of the stop mechanism 8 is arranged at the front side (downstream side in the opening direction) of the rescue exit cover plate. By arranging the locking mechanism 6 on the car top plate near the rear side (upstream side in the opening direction) of the rescue exit cover plate 4 as described above, and arranging the movable part 81 of the stop mechanism 8 at the front side (downstream side in the opening direction) of the rescue exit cover plate, when the rescue exit cover plate 4 is in the closed position, while the rear side of the rescue exit cover plate 4 is pressed by the locking plate 62 of the locking mechanism 6, the front side of the rescue exit cover plate 4 is also fastened by the engagement of the movable part 81 of the stop mechanism 8 with the fixed part 82, thereby preventing the rescue exit cover plate 4 from moving or loosening to cause danger during normal operation of the elevator.
[0070] like Figure 3 As shown, the movable part 81 has a concave part, and the fixed part 82 has a convex part whose shape matches the concave part. However, the fixed part 82 may have a concave part, and the movable part 81 may have a convex part whose shape matches the concave part, as long as the shapes of the fixed part 82 and the movable part 81 match each other and can be firmly joined together.
[0071] Figure 3 2 shows a case where the movable portion 81 and the fixed portion 82 of the stopper mechanism 8 are joined by a mechanical snap. The worker applies a predetermined force to the rescue exit cover 4 provided with the movable portion 81, thereby enabling or disabling the mechanical snap.
[0072] Specifically, in the rescue structure of the elevator car top of the present embodiment, after the locking mechanism 6 releases the lock on the rescue exit cover plate 4, the operator applies a force to the handle 41 in the opening direction to at least release the locking of the fixed portion 82 and the movable portion 81, and the rescue exit cover plate 4 can start to move from the closed position to the open position. In contrast, when resetting from the open position to the closed position, the operator applies a force to the handle 41 in the closing direction to at least release the locking of the fixed portion 82 and the movable portion 81, and the rescue exit cover plate 4 can be reset to the closed position.
[0073] In addition, if Figure 3As shown, the rescue structure of the elevator car top of the present embodiment may also include a block 21 arranged on the car top plate 2. When the rescue exit cover 4 is reset from the open position to the closed position, when the rescue exit cover 4 slides to the closed position, the rear side of the rescue exit cover 4 as the downstream side in the closing direction abuts against the block 21. As a result, the block 21 prevents the rescue exit cover 4 from moving further in the closing direction, thereby being able to function as a limiting member for limiting the position of the rescue exit cover 4 in the same way as the stop mechanism 8, and being able to more reliably prevent the switch contact 72 installed on the rescue exit cover 4 from colliding with the switch body 71, and the rescue exit cover 4 from colliding with the locking mechanism 6.
[0074] [Movement to rescue the structure]
[0075] Next, the operation of the rescue structure for the elevator car top according to the present embodiment will be described.
[0076] The rescue structure of the elevator car top of the present embodiment is configured so that the locking mechanism 6 can be unlocked both from outside the car and from inside the car, and accordingly, rescue is divided into rescue outside the car and rescue inside the car (self-rescue).
[0077] <Rescue situation in the car>
[0078] In-car rescue is achieved by operators or passengers operating from inside the car, including the following actions:
[0079] 1) The lock member 61 serving as the triangular lock is unlocked with a triangular key in the car, and the lock member 61 drives the lock plate 62 to rotate to a position where it is separated from the upper surface of the rescue exit cover plate 4.
[0080] 2) The rescue exit cover 4 is forced in the opening direction from the lower surface thereof, so that the switch contact 72 is separated from the switch body 71 and the movable portion 81 is separated from the fixed portion 82, and the rescue exit cover 4 starts to slide in the opening direction.
[0081] 3) Continue to apply force to the rescue exit cover plate 4 in the opening direction from the lower surface of the rescue exit cover plate 4, so that the rescue exit cover plate 4 slides in the opening direction until the rescue exit 3 is completely exposed.
[0082] <Rescue outside the car>
[0083] Rescue outside the car is achieved by operators or passengers operating from the top of the car, including the following actions:
[0084] 1) The lock plate 62 is directly rotated from the car top side to a position where it is disengaged from the upper surface of the rescue exit cover 4 .
[0085] 2) A force is applied to the handle 41 in the opening direction, so that the switch contact 72 is separated from the switch body 71 and the movable portion 81 is separated from the fixed portion 82, and the emergency exit cover 4 starts to slide in the opening direction.
[0086] 3) Continue to apply force to the handle 41 in the opening direction, so that the rescue outlet cover 4 slides in the opening direction until the rescue outlet 3 is completely exposed.
[0087] <Reset>
[0088] 1) On the car top side, force is applied to the handle 41 in the closing direction to move the rescue exit cover 4 to a position where the movable portion 81 is engaged with the fixed portion 82 and the switch contact 72 is connected to the switch body 71 .
[0089] 2) Rotate the lock plate 62 to a position where it presses against the upper surface of the rescue exit cover 4 .
[0090] [Effect]
[0091] In the rescue structure of the elevator car top of the present embodiment, the rescue exit cover is set to be able to slide, so that the upper space of the car top can be saved compared with the existing situation where the rescue exit cover is flipped up. Therefore, the rescue structure of the elevator car top of the present embodiment is particularly effective for situations where the car size is small and the top floor space is insufficient.
[0092] In the rescue structure of the elevator car top of the present embodiment, the safety switch mechanism stops the elevator as the sliding of the rescue exit cover plate starts, thereby preventing accidents caused by accidental operation of the elevator during rescue.
[0093] In the rescue structure of the elevator car top of the present embodiment, the stop mechanism serves as a fastening component during closing and a limiting component during resetting. Therefore, the rescue exit cover can be prevented from shifting during closing, and the switch contacts installed on the rescue exit cover can be prevented from colliding with the switch body, and the rescue exit cover can be prevented from colliding with the locking mechanism during resetting.
[0094] A stopper is provided in the rescue structure of the elevator car top in the present embodiment, so that the rescue exit cover plate abuts against the stopper when it slides to the closed position during resetting. As a result, the stopper prevents the rescue exit cover plate from further moving forward in the closing direction, thereby being able to act as a limiting component for limiting the position of the rescue exit cover plate in the same way as the stop mechanism, and being able to more reliably prevent the switch contacts installed on the rescue exit cover plate from colliding with the switch body, and the rescue exit cover plate from colliding with the locking mechanism.
[0095] In the rescue structure of the elevator car roof of the present embodiment, when the rescue exit cover is in the closed position, the rear side of the rescue exit cover is pressed by the locking plate of the locking mechanism, and the front side of the rescue exit cover is fastened by the snap fastening of the movable part and the fixed part of the stopping mechanism. Therefore, the rescue exit cover can be reliably locked relative to the top plate, and the rescue exit cover can be prevented from moving or loosening to cause danger during normal operation of the elevator.
[0096] [Second embodiment]
[0097] Reference Figure 5 A rescue structure for an elevator car top according to a second embodiment will be described.
[0098] The difference between the second embodiment and the above-mentioned first embodiment is that the stopping mechanism 8 of the first embodiment is constructed so that the fixed part 82 and the movable part 81 are mechanically snapped together when the rescue exit cover 4 is in the closed position, while the stopping mechanism 8 of the second embodiment is constructed so that the fixed part 82 and the movable part 81 are electrically magnetically attracted to each other when the rescue exit cover 4 is in the closed position, and the magnetic attraction is released in conjunction with the switch body 71 and the switch contact 72 of the safety switch mechanism 7 being in the disconnected state.
[0099] The stop mechanism 8 and the safety switch mechanism 7 are as follows Figure 5 The safety switch mechanism 7 is electrically connected as shown by the double dotted line in the figure. When the switch body 71 and the switch contact 72 of the safety switch mechanism 7 are in the on state, the movable part 81 and the fixed part 82 of the stop mechanism 8 are electrically magnetically engaged, and in conjunction with the switch body 71 and the switch contact 82 becoming the off state, the stop mechanism 8 electrically releases the above-mentioned magnetic attraction.
[0100] Figure 5 The magnetic attraction is shown as an electrical one, but it may not be an electrical one, but the movable part 81 and the fixed part 82 may have opposite magnetism to each other and can be attracted and joined to each other. In this case, the operator can manually apply a force to the rescue exit cover 4 toward the opening side to release the magnetic attraction between the movable part 81 and the fixed part 82.
[0101] In addition, since the movable portion 81 and the fixed portion 82 in the present embodiment are joined by magnetic attraction, both of them do not need to be formed in a concave-convex shape, and may be formed in a flat surface.
[0102] In addition to the effects of the first embodiment, the rescue structure of the elevator car top of the second embodiment is able to lock and release the electrical magnetic attraction while separating the switch body 71 and the switch contact 72 of the safety switch mechanism 7 by setting the fixed part 82 and the movable part 81 as electrical magnetic attraction. Therefore, there is no need to apply external force to release the mechanical buckle of the first embodiment to make the rescue exit cover slide smoothly.
[0103] [Third embodiment]
[0104] Reference Figure 6 , 7 A rescue structure for an elevator car top according to a second embodiment will be described.
[0105] The third embodiment is different from the first embodiment in that the rescue exit cover plate 4 of the first embodiment is formed as a whole sheet, while the rescue exit cover plate 4 of the third embodiment includes a front rescue exit cover plate 42 and a rear rescue exit cover plate 43 which are divided in the front-to-back direction. Figure 6 As shown, the front rescue exit cover plate 42 and the rear rescue exit cover plate 43 are connected by a hinge 44. After the locking mechanism 6 is unlocked and the switch body 71 of the safety switch mechanism 7 is connected to the switch contact 72, the rear rescue exit cover plate 43 can be opened as shown in FIG. Figure 7 As shown, the emergency exit cover 42 is folded on the front side and slid in the folded state.
[0106] In addition to the effects of the first embodiment, the rescue structure of the elevator car top of the third embodiment is that the rescue exit cover 4 is divided into a front rescue exit cover 42 and a rear rescue exit cover 43, and both are set to slide in a folded state. Compared with the case where the division and folding are not performed, the distance occupied by the rescue exit cover in the sliding direction becomes smaller (halved), thereby being more conducive to saving space on the car top plate.
[0107] [Fourth embodiment]
[0108] Reference Figure 8 , 9 A rescue structure for an elevator car top according to a fourth embodiment will be described.
[0109] The fourth embodiment is different from the first embodiment described above in that the rescue exit cover plate 4 of the first embodiment is formed as a whole sheet, while the rescue exit cover plate 4 of the third embodiment includes a front rescue exit cover plate 42 and a rear rescue exit cover plate 43 which are divided in the front-to-back direction, and when sliding from the closed position to the open position, the front rescue exit cover plate 42 and the rear rescue exit cover plate 43 are as follows: Fig. 9 As shown by the hollow arrows in the figure, the two components slide toward the front and rear sides in a manner away from each other, and the locking mechanism 6 and the safety switch mechanism 7 are moved from the rear side of the rescue exit cover 4 to the middle position.
[0110] Specifically, if Figure 8 As shown, in the safety switch mechanism 7, the switch body 71 is arranged on the rear rescue exit cover 43, and the switch contact 72 is arranged on the front rescue exit cover 42. Here, the setting positions of the switch body 71 and the switch contact 72 can also be interchanged, as long as they are arranged on different rescue exit covers.
[0111] In addition, the locking mechanism 6 is constructed to be arranged on the car top plate 2, near the left side of the front rescue exit cover plate and the rear rescue exit cover plate, at the approximate junction of the front rescue exit cover plate and the rear rescue exit cover plate, so that the upper surfaces of both the front rescue exit cover plate 42 and the rear rescue exit cover plate 43 can be pressed toward the car top plate at the same time by the locking plate 62.
[0112] Furthermore, the movable portion 81 of the stopper mechanism 8 is configured so as to be provided on the front side of the front rescue exit cover 42 and to be provided on the rear side of the rear rescue exit cover.
[0113] The rescue structure of the elevator car top involved in the fourth embodiment is as follows Fig. 9 As shown, during rescue, after the locking of the locking mechanism 6 and the connection between the switch body 71 and the switch contact 72 of the safety switch mechanism 7 are released, the front rescue exit cover 42 and the rear rescue exit cover 43 move forward and backward respectively until the rescue exit is completely exposed.
[0114] In addition to the effects of the first embodiment, the rescue structure of the elevator car top of the fourth embodiment can use the locking mechanism 6 and the safety switch mechanism 7 for both the front rescue exit cover plate 42 and the rear rescue exit cover plate 43 by moving the locking mechanism 6 and the safety switch mechanism 7 from the rear side of the rescue exit cover plate 4 to the middle position. Moreover, the rescue structure of the elevator car top of the fourth embodiment is particularly suitable for the case where the rescue exit is set in the center of the car top.
[0115] [Fifth embodiment]
[0116] Reference Fig.10 A rescue structure for an elevator car top according to a fifth embodiment will be described.
[0117] The fifth embodiment is different from the fourth embodiment described above in that a spring 45 having an electrical switch (not shown) is further provided on the front rescue exit cover 42 and the rear rescue exit cover 43. When the electrical switch is turned on, the spring 45 pulls the front rescue exit cover 42 and the rear rescue exit cover 43 away from each other, thereby exposing the rescue exit 3.
[0118] In addition to the effects of the fourth embodiment, the rescue structure of the elevator car top of the fifth embodiment is that the spring 45 can be automatically opened and reset by operating the electrical switch, and the rescue exit cover can be opened and closed without manual operation, which saves time and effort and is convenient to operate.
[0119] The above-mentioned rescue structure of the elevator car top is described by taking the elevator with a single-side door as an example, and can also be applied to elevators with opposite double-side doors. When applied to elevators with opposite double-side doors, the front side and the rear side in the above-mentioned embodiment are one side and the other side in the depth direction of the elevator.
[0120] The above describes an embodiment of the utility model, but the embodiment is only presented as an example and is not intended to limit the scope of the utility model. The new embodiment can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the utility model. These embodiments and their variations are included in the scope and purpose of the utility model, and are included in the scope of the utility model and its equivalents recorded in the claims.
