SOLUTION: An elevator system has plural units of elevator cars, making them travel in the vertical direction in adjacent hoistways. These cars are traveled as the ranged segments. Those of respective segments are connected to each other by a rope, and provided with paired couplers driven by an elevator traction machine 37. These segments are stopped when the car is reached to an end of the said segment, and the elevator car is traveled from the coupler of one segment to the segment of the adjacent coupler with a varied closed loop rope equipped with these paired couplers, without a stop. At an upper passenger landing, the car is traveled by an overhead trolley, and at a lower passenger landing, it is traveled by a carriage (dolly) in an interval between each individual hoistway and a vestibule landing, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator for use in a skyscraper, and more particularly, to a hoisting mechanism in which a plurality of cars overlap each other in an ascending hoistway and a descending hoistway. The hoisting mechanism has ropes connected from a car coupler to another car coupler, and in one embodiment these couplers are stopped when changing the car. Or in another embodiment, the hoisting mechanism comprises:
An elevator system configured to move a car from one coupler to another while moving the car.

[0002]

2. Description of the Related Art In skyscrapers, it is known that passengers going to the highest part of the building are exercised by row elevator means, while the lower elevators are Passengers are moved to one sky lobby, and then the passengers walk to another elevator that takes them to a second sky lobby. Thereafter, the passengers split into third floor elevators to move to each floor elevator or yet another sky lobby. The higher the building, the more difficult it is to find enough room for the elevator needed to move many passengers to the highest part of the building. Therefore, it is extremely demanded to use the elevator hoistway space more efficiently as the floor becomes higher.

[0003] Another problem in skyscrapers is that the weight of the elevator rope (which is a steel cable to support the car and counterweight) is
This does not allow the use of a rope system that exceeds about 120 floors. Yet another problem with conventional elevators is that the car is continuously roped by its counterweight and moves up and down the hoistway, so that only one elevator car can occupy the elevator hoistway at a time.

It has been pointed out that some of these problems can be solved by using an elevator driven by a linear electric motor (LEM). This linear electric motor is configured to be able to directly apply a driving force from a building structure to an elevator car. However, because of the lack of counterweights, the current size and power consumption of LEMs for driving elevator cars makes them unsuitable for use in elevator services for hundreds of floors. It has not been considered.

[0005] In co-pending US application Ser. No. 08 / 564,754, filed Nov. 29, 1995, the elevator cab is mounted within a car frame within the first hoistway. Is moved to the waiting moving floor. The cab is adapted to move to an adjacent hoistway car frame for further movement. Moving the above cab to the adjacent hoistway is time consuming,
Moreover, it was unpleasant for passengers.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the height limitation of elevator service due to the weight of the rope to support the elevator, and to allow one or more elevator cars to stay in one hoistway for a certain period of time. Another object of the present invention is to provide an improved high-efficiency elevator system for high-rise buildings. The object in one embodiment of the present invention can be achieved by eliminating the need to stop the cab when moving the cab while the elevator is running.

[0007]

In accordance with the present invention, a plurality of elevator segments are extended between several floors of a building, each segment forming a pair traveling along a passage adjacent to one another. Has a basket coupler. These passages are adapted to vertically overlap one another in the above-mentioned segment with the adjacent passages provided with another pair of couplers. Further, the couplers are each adapted to selectively couple the rope to the car. Each paired coupler is roped together to counterbalance each car with respect to the other. Each coupler is adapted to move up and down alternately, first of all, the car is connected so as to move upward,
The cars are then coupled for downward movement such that the cars connected thereto alternately move up and down in synchronization with each other. In this case, in the above system,
Two baskets are used per pair.

In yet another embodiment, as each car reaches the end of one of the segments, the coupler stops, and while stopping, the next segment in the direction the car travels while stopping. Each car is connected to the coupler, and then the coupler that has moved the car is disconnected. Thereafter, the couplers are all changed in their direction, accelerating and moving each car in each direction. Each pair of couplers is sequentially connected to a car in the hoistway for ascending, stopped and then connected to a car in the descending hoistway, and then from that car in the hoistway for ascent. Another coupler, which has been disconnected and associated therewith, is connected to the car in the hoistway for moving down substantially simultaneously and alternately, stopped and connected to the car in the hoisting hoistway. After that, it is separated from the car in the hoistway that runs down.

In yet another embodiment, each car, when approaching one end of the segment, comprises two couplers that are roped together in a closed loop and connected to the coupler of the balanced shuttle segment. These couplers correspond to the direction in which the car will move at the next point in time. Thereafter, the coupler that had previously moved the car within the segment is disconnected. The disconnected pair of couplers is adapted to be decelerated, stopped, parked, returned in the opposite direction, and then accelerated to connect to the oppositely traveling car pair. Each coupler of the car pair is connected in turn to a car in the hoistway for ascending, disconnected from the one in the opposite direction, and then connected to a car in the hoistway to travel down. At the same time, the other couplers of this pair are alternately connected to the car in the hoistway running at the same time in a downward direction, disconnected, run in reverse, and then connected to the car in the hoistway that rises. ing.

In a second embodiment, an unbalanced, single-coupler, deceleration / acceleration shuttle with a single coupler is between the lowest coupler segment and the lower passenger landing and at the top. Required between coupler segment and upper passenger landing. In this embodiment, a linear electric motor (LEM)
Is used for this unbalanced shuttle.

According to a further aspect of the present invention, the car at rest on the service floor of the building is disconnected from the coupler, removed from the hoistway, and directed to the passenger lobby, where the passenger is You can get on and off the car. Furthermore, according to the invention, the removal of one car from one hoistway is performed substantially simultaneously with the return of another car to another hoistway.

The present invention can be practiced with a self-holding coupler having a holding surface elevated at a moderate angle. The connection / disconnection of the surfaces is performed by moving along a predetermined path which is at an angle significantly larger than the contact surface.

[0013] Other objects, features and advantages of the present invention will become more apparent from the detailed description of exemplary embodiments thereof taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 3, only the cars A to D among the plurality of elevator cars are designated by reference numerals.
Between 2 and the upper landing 33 (FIG. 3), it moves in an elevator system having 6 segments PU. Each of the segments P to U drives a driving rope 36 extending between the paired car couplers W and X or between Y and Z, and further includes a normal brake 39.
And a traction machine 37 for driving a drive sheave 38 having In FIG. 2, the couplers W and Y are indicated by broken lines, and this W is a plane (paper surface) of the cars A and B in FIG.
It should be noted that Y is below that plane (paper plane). In the lowermost view of FIG. 3, the black couplers are those that have moved or are moving upwards, and the white couplers are those that have moved down or have moved down. I have. FIG.
In FIGS. 1 and 2, the coupling means 41 of the coupler Z is connected to the coupling means 42 of the car A, and the coupling means 41 of the coupler X is connected to the coupling means 42 of the car B. The connection is shown. As can be seen in FIG. 2, each of the couplers W-Z is bidirectional and connects to either an ascending hoistway (car A) or a descending hoistway (car B). Is available.

In FIGS. 3-7, cars A and C moving upward are shown in front of cars B and D moving downward. The couplers W to Z are located between the path of the car moving upward and the path of the car moving downward. These paths are called "hoistways". In FIGS. 1 to 3, the car A is connected to the coupler Z.
Is wound up to the top of the segment P and stopped, and the car B is lowered by the coupler X to the bottom of the segment Q and stopped. FIG.
Then, the coupler X is connected to the car A, and the coupler Z
Is connected to car B. When these new couplers are connected, the previously connected coupler is
It is designed to be separated. Therefore, the coupler Z is disconnected from the car A, and the coupler X is disconnected from the car B. Each coupler is adapted to be connected to these two cars once during the movement process.

In FIG. 5, car B has been lowered to the lower passenger landing by the coupler Z of segment P (see FIGS. 3 and 5 and the description above). Car A has been raised to the top of segment Q by coupler X, and coupler W has lowered car D to the bottom of segment Q. In FIG. 6, the coupler W of the segment Q is connected to the car D, and then the coupler Y of the sector P is disconnected from the car D.

In FIG. 7, car A has been raised by coupler Z to the top of segment R and car D
Is lowered to the lower landing by the coupler Y of the segment P. These movements are such that each coupler moves in a first direction (up or down) and stops, and then the car is coupled to its adjacent segment of couplers in the same direction (up or down). direction)
You can be exercised and continue to reach the next level. Although only four cars are shown in FIGS. 3-7, each of the five intermediate levels always accommodates two cars, one of each of the upper landing and the lower landing. The car is adapted to either arrive or depart. Thus, FIGS. 3-7 always show twelve cars, some of which, like adding more cars to these landings, may be omitted for simplicity as described below. it can.

In FIG. 2, each of the above couplers is precisely confined in a vertical path by means of a conventional guide roller (not shown) or conventional guide rail 43 means used in conjunction with another guide roller. Is shown. In FIG. 2, four guide rails are shown for each coupler, but two or more guide rails can be used as desired. The above basket A,
H is also provided with openable guide rollers 45 or paired guide rails 44 which are used in cooperation with suitable openable guides, respectively. , So that the cars A to D can be taken out from the hoistway to the passenger landing. This will be described later. In the embodiment described in FIGS. 1-7, the W and X couplers are in one segment (eg, segment Q), and these are the Y and Z couplers of the segment above it, or the The R and P couplers are prevented from interfering with each other.

Referring to FIG. 8, the coupling means 41 at one end of the coupler Z is provided with a coupling surface 4 having an appropriate inclination angle.
9 having a plurality of teeth 48 provided with the coupling means 4 of the elevator car, for example A.
It is shown adapted to engage a corresponding surface 50 of the second tooth 51. The inclination of each surface 49, 50 is
By adding the weight of the car A to the tooth portion 48, the coupler is moved to the surfaces 49 and 50 as shown in FIG.
Are sufficiently adjacent to each other to the engagement position. The angle shown in FIG. 8 is set to 15 °, but may be set to another angle. The teeth 48 are disposed on at least one plate 52 connected to sector gears 55 and 56 via arms 53 and 54. These gears 55 and 56 are driven in opposite directions by a motor 57 having a gear 58 for driving the sector gear 55. The gear 58 drives a pinion gear 59 that drives the sector gear 56. As shown in FIG. 8, when the sector gear 55 is rotated counterclockwise and the sector gear 56 is rotated clockwise, the plate 52 moves upward and outward while being regulated by the paired guide rails 60 and 61. The engagement position shown in FIG. Instead of rotating the sector gear, a linear actuator such as a hydraulic piston actuator or a screw jack may be used to advance the plate 52 to the engagement position or to retract the plate 52 to the retracted position shown in FIG. Can be used. In this disengaged position, the teeth of the coupler do not engage the teeth of the car, so that the car and the coupler can move freely adjacent to each other. 8 and 9
In the above, the guides 60 and 61 and the corresponding edges 62 and 63 of the plate 52 are formed at a predetermined angle (for example, about 45 °), which is sufficient for the surfaces 49 and 50 (about 15 °). , The plate 52 is pulled in (toward the lower right side in FIG. 8).
Upon decoupling the surfaces 49, 50, the car (car A) will be held by the most recently engaged different coupler (or, in the embodiment of FIG. 11, move upward or downward). Will continue). Since the weight of the car is also supported by other couplers, the bottom of the teeth 48 slides along the top of the teeth 51. Similarly, the surface 49 is adapted to engage the surface 50 by an upward left movement,
This is because the angle (6) is larger than the angle of the surfaces 49 and 50.
0-63 °), wherein the car (eg, car A) is shown to be held by a previously engaged coupler (or move in either an upward or downward direction). Depending on that). The coupler operates in the same manner regardless of whether the car and the coupler are moving upward or downward. In addition, the coupler W
8 to 9 have the same mechanism on the opposite side surfaces in FIGS. It will be appreciated that the scope of the present invention includes couplers different from those disclosed in FIGS. 8 and 9, such as co-pending U.S. patent applications of common assignee, application number being Attorney Docket In O
The coupler described in T-3036 can also be used. These couplers may be connected by biasing means. Alternatively, the coupler may be engaged after using a lifting latch as shown in FIG.

Referring to FIG. 2, the motor 37 has been selected to fit within the space of the elevator. Sheave 38 to be the central part of the rope 36
If there is not enough space on one side of the motor 37

For example, it may be driven by a pair of ropes 36a and 36b connected to the end of the coupler Z. In the figure,
Only one sheave 38a is shown. On the other hand, a flat synchronous or another type of machine could be used. An inside-out type motor having a center stator integrated with a sheave and an outer rotor can also be used if desired.

In order to remove the car from the hoistway, a trolley is used in the upper passenger landing, and a dolly, guide, for example, a roller guide 45 is used in the lower passenger landing.
Can be used. These guides guide each car along the guide rails, and also allow the car to slide from the guides to the sideways so that the guide rails and the rollers can slide without interfering with each other. It must be open. In this embodiment, the guide rails 44 are extended vertically as needed to guide the car to a position sufficient to allow the car to be picked up by a trolley or to rest on a dolly. In order to avoid this rail 44, the roller guide is lifted above the rail in the case of the upper passenger landing and below the bottom of the rail in the case of the lower passenger landing. Can be lowered.

FIG. 11 shows a roller guide 45 which can be freely opened.
Is a post type roller 305 and two side rollers 30
6 is shown as usual. The rollers 305, 306 are mounted on a normal adjustment bracket assembly 307, which is arranged on a shelf 308 of a movable block 310. A portion of the guide rail 44, which is shown small, is shown displaced to the left from a position where the guide rail 44 is engaged with the rollers 305, 306 in use. Block 310 above
Has clearance holes 312 and 313,
These correspond to the lots 314 and 315 for guiding the movable block 310. The block 310 has a threaded hole 318, which is a thread or worm gear 31.
9 are accommodated. The worm gear 319 is always rotated by a motor when the guides 305 and 306 are adjusted up and down. The motor 320 is formed in the upper support 322, and the lower end of the screw 319 is rotatably supported in the lower block 323. Guide rods 314, 31
5 is an upper support block and a lower support block 322,
323. Block 32 above
2, 323 may be arranged on the side of the elevator opposite the coupling means 42. When the elevator travels in the hoistway, the block 310 is located at the center in the vertical direction between the support 322 and the support 323. When the car is connected to the trolley in the upper passenger landing, the block 310 is driven to the upper limit by driving the screw 319 by the motor 320 to move the block 310 to the upper limit. 306 and assembly 307 avoid the top of the guide rails and allow the car to move in a direction parallel to the two guide rails (in the north-south direction of the landing). If desired, more than two rollers can be used as usual, as described in co-pending U.S. patent application Ser. No. (Attony Docket No. OT-3039) by a common applicant. Have been.

In this embodiment, it is preferable to mount an openable roller guide 45 along an intermediate portion in the vertical direction of the side of the elevator. In this manner, the engagement of the coupler and the coupling Alternatively, the greatest resistance can be generated against the separation of the car. On the other hand, if desired, said releasable roller guide 45 is arranged at the top of the elevator car side and is applied from the roller guide to the opposite side and the torque moment generated by the coupler holding the car. Can be given the greatest resistance. Of course, other arrangements can be used. Whenever the car is lowered to a position where the car is held in the dolly during the lower passenger landing, the motor 320 rotates the screw 319 in the direction of lowering the block, and the guide 305, 30
6 and assembly 307 are configured to avoid the bottom of the guide rail as the car moves laterally to the landing.

Referring to FIG. 12, upper passenger landing 33 includes an upward hoistway 202 and a downward hoistway 20.

9 (the names of North and South are for convenience and do not specifically correspond to azimuth). The elevator car is adapted to move on a passenger landing along guideways, i.e., tracks 211-220, by means of six trolleys. This trolley straddles the truck of FIG. 15 or FIG.
For example, indicated by trolley 223. This will be further described later. Dashed line 210 indicates the outer line of the elevator car that enters and exits the hoistway.
Each elevator car moving upwards reaches the above-mentioned hoistway, moves to one of the disembarkation lobbies (north or south), opens its doors and lowers passengers. I have. The car then travels to the opposite lobby (south or north), reopens its doors, and allows passengers to board. When the car is loaded and the door is closed, the car is moved to a downward hoistway, and is lowered downward by a hoisting mechanism inside the car. In Izure north lobby or south lobby, because the car has two sets of doors, it is possible to use any car in order to dismount or riding. Whenever the car is in the disembarkation or boarding lobby, it is slightly lifted and stabilized by the four jacks 250 arranged as shown. As a result, the trolley is opened and allowed to move.

Referring to FIG. 13, FIG. 13 (a) shows that the first car A is about to descend into the down hoistway 203. These cars are shown as A-J in FIG. 13 and are not the same as the particular cars A-J in FIGS. The second basket B is
Passengers are boarded in the south boarding lobby 209, and the third car C is moved from the south getting off lobby 208 below the east circular truck 211 toward the north boarding lobby 207. The fourth car D moves down the west circular truck from the north getting off lobby 206 toward the south boarding lobby 209. The fifth car E has passengers disembarked in the south disembarkation lobby 208, and the sixth car F has just arrived at the upward hoistway 202. In FIG. 13 (b), car B moves toward the down hoistway, car C carries passengers, car D continues to circulate through the circular path, and car E
However, the passenger F is kept off, and the car F is moved from the upward hoistway to the north disembarkation lobby. FIG.
At 3 (c), car B is ready to descend in the down hoistway, car C continues to carry passengers, and car E is empty at this point. It is moving from the south disembarkation lobby to the disembarkation lobby on the circular walkway in front. Car D travels along with car E to the south boarding lobby through the south alighting lobby. The circular path rotates the car as shown in FIG. Car F disembarks the passenger and car G
It is ready to proceed to the above-mentioned hoistway and move to the above-mentioned south exit lobby,
The passenger is just being carried away by car E. This operation is continued as shown in FIGS. 13 (d) to 13 (i).

FIG. 14 shows how the plurality of cars are rotated in the upper landing 201.
As shown in (a) to (c), these figures show the arrangement of the car F when moving from the north getting off lobby 206 to the south boarding lobby 209 through the west circular path.
In FIG. 14 (a), the coupling means 42 of the car F is facing east, which is rotated as the car passes through the circular path, and the coupling means 42 is turned to the state shown in FIG. ) Is facing west.

In this embodiment, a total of six trolleys are used. That is, two shaft trolleys are used between the shafts and the lobby.
Four trolleys are used between the disembarkation lobby and the boarding lobby, and these four trolleys are shown as K to N in FIG. In this embodiment, on the oval path below the tracks 211 to 218,
No more than one car is allowed to move between the disembarking lobby and the boarding lobby. Therefore, four trolleys are required for this oval passage. These four trolleys K to N are opened each time the car reaches the disembarkation lobby or the boarding lobby and are lifted by the jack 250, and the car is completed when boarding or dismounting is completed in one of the disembarking lobby or the boarding lobby. The trolley is always connected to the car. However, the trolleys K-N are shown only when they are not connected to a car, but in a position such that they can pick up another car once they have completed their disembarkation. It is because it is advanced to. In each case, the trolley opened at the north boarding lobby picks up the car at the south boarding lobby. As shown in FIG. 13, the trolleys K, M
Is opened at the north boarding lobby, picks up the car at the south boarding lobby, and the trolleys L, N move to open the car at the south boarding lobby and pick up the car at the north boarding lobby, respectively. Go. The basket is
Note that the trolley, when held by the jack, is allowed to pass unobstructed by the car. Also, when the trolley releases the car, the trolley is left on the car until another trolley appears on the approach. Therefore, FIG.
In (c), the trolley M can be stopped in the north boarding lobby after opening the car C, and then the car F
Immediately after passing, the hoistway trolley that has carried the car F to the north alighting lobby is returned toward the hoistway.

The method of moving two cars at a time from the upper hoistway to the lower hoistway via the getting-off lobby and the boarding lobby is such that one elevator car arrives every 15 seconds. Since the speed can be adjusted appropriately, it is acceptable to set 17 or 18 seconds for the disembarkation lobby and 17 or 18 seconds for the boarding lobby, and about 6 seconds for each to exercise. It can be. The movement between the hoistway and the lobby is somewhat slower, because they are relatively close to each other and there are passengers inside the car. This movement between the disembarkation lobby and the boarding lobby can be performed at a higher speed without having to consider the passenger's ride because the car is now empty.
It can be used even at another timing.

Referring to FIGS. 15-17, each trolley 223 has a main plate 224 supported by eight wheels 225, and the eight wheels 2
25 is supported on the plate 224 by means of brackets 226 secured by welding, bolting (not shown), or the like, or other methods as needed. These wheels 225 are mounted on the bracket 22

A similar lifting ring 256 (FIG. 20) to be used is required, by means of which said lifting latch 240 or similar lifting latch 257 disposed on the hoistway trolley 259 or the bottom plate 258, respectively.
The passage shown in FIG. 19 is not blocked. The two patterns shown in the bottom views of the oval trolley 223 (FIG. 18) and the hoistway trolley 259 (FIG. 19) are used in conjunction with the trolleys K-N to lift the respective car lifting eyes 241. And lifting eye 2 used in cooperation with hoistway trolley 259
59 patterns are formed. Of course, other arrangements can be used as desired. Since the hoistway trolleys only move a short reciprocating distance, they can be powered by cables extending from the top support structure. The oval trolley may be a normal power rail,
If the trolley has a passive secondary part, it is necessary that the track be an active primary part.

At the bottom of the hoistway, this situation is opposite to that at the top. It is possible to support the object from the bottom, since there are no obstacles from above. In FIG. 21, the elevator cars are housed at the bottom end of the down hoistway 203 at the lower landing 260, and these are the north get off lobby 262 or the south get off lobby 2
Exercise to 63 is shown. In this case,
The car door is opened so that passengers can get off the car. Then, each car moves counterclockwise from the above-mentioned South Exit Lobby or North Exit Lobby to the South Boarding Lobby or North Boarding Lobby 264, 265, where the door is reopened and passengers enter the car. Get on. Thereafter, the car moves up the hoistway and moves to the upper passenger landing in FIG.

In this embodiment, each elevator car is lowered directly onto dolly 268 (FIG. 22). The dolly has a plurality of casters 269 that rotate within a track 270 that defines the path of the dolly. The casters 269 are rotatable in any direction to move in a well-known manner. The dolly 268 includes an LEM primary portion 271 disposed on the lower landing floor 267.
And a T-shaped LEM secondary portion 272 disposed below and adjacent to the primary portion 271 so as to be moved along the track by LEM means. The above LEM primary part 27
As shown in FIG. 21, 1 is disposed between the downward hoistway 203 and the south getting off lobby 263. Another LEM
The primary portions 273 to 280 move the counterclockwise route from the south exit lobby 263 to the north boarding lobby 264.
Up to and from the North Disembarkation Lobby to the South Boarding Lobby 26
5 are formed. Primary part 281, 282
From the down hoistway 203 to the north get off lobby 26
2 and the primary part 283-2
85 provides a route from the boarding lobbies 264, 265 to the hoistway 202. Primary part 286
Is configured to return the dolly, and when the car is no longer heading from the upward hoistway to the downward hoistway, another car is serviced. In the upper passenger landing, the jack 250 opens the lift latch on the trolley to allow the trolley to move and move the various trolleys sequentially to their respective cars. FIG.
In the embodiment described above, the dolly at the lower passenger landing receives the car and is waiting with the car until it moves from its landing. afterwards,
Since the dolly from this can be used for further purposes, it moves to the lower side of the above down hoistway,
It waits for the next car to come down.

FIG. 21 shows that the truck 270 at the south get-off lobby houses a dolly with four casters. In this case, the casters are aligned along the track in the direction of movement of the dolly and remain aligned when stopped. For example, from the down hoistway 203 to the south get off lobby 26
Dolly, moving up to three, has its casters pointing in the direction originally coming from the down hoistway (north / south).
When the force is applied to move the dolly to the left,
The dolly aligns the casters laterally, but the shape of the intersection easily rearranges the casters into a truck (east / west), which is the process of the dolly in the south exit lobby 263. Is shown. The use of LEM secondary and simple casters makes it possible to construct a passive dolly that does not require power. Of course, other arrangements could be used to move the elevator car in the lower passenger landing.

Also, if desired, the casters and L
The EM secondary may be located at the bottom of each car, which may eliminate the need to use the dolly.

In a second embodiment of the present invention, the convenience of the elevator core space is maximized by eliminating the need for a stop at the end of the segment (segment P or Q) shown in FIGS. It is to be. In this case, a closed loop rope having two couplers is used in the shuttle so that the car moving from another segment P is delivered without stopping to a segment such as Q. .

Referring now to FIG. 23, closed rope loop 330 has couplers M and N connected thereto and constitutes a segment V, which is comprised of segments P and Q. It is positioned between. This rope loop 330 is used for idle sheave 3
31 is provided around the drive sheave 332.
Has an ordinary brake and a motor 333 to form an elevator traction machine for driving the loop 330. Other than connecting the rope loop 330,
The coupler M and the coupler N are the same as in the first embodiment. Each of the couplers M and N of the loop 330 does not interfere with the X-coupler and the Y-coupler due to the vertical separation as shown in FIG. At the time shown in FIG. 23, the loop 330 has moved counterclockwise as shown, the coupler N has moved upward, the cab has moved upward, and the coupler M is exercising downward, and cab B is exercising downward. Immediately before the time shown in FIG. 23, the coupler M and the coupler N are accelerated from the rest position, and the car A
And synchronization with car B, ie, equal speed. At the next point in time, couplers X and Z are disconnected from cab B and cab A, respectively, and as the car moves through the loop, both couplers X and Z
Is decelerated to a stop. The car continues to move through the loop. The couplers X and Z reverse their directions, and are accelerated so that the coupler Z moves the car B downward from the coupler M, and the coupler X
Moves the car A upward from the coupler N.

For example, when the cars A and B are moving at a speed of about 10 m / s, the counterweights connected to the ropes and the couplers X and Z are decelerated at a gravitational acceleration of about 10 m / s ^2. . Therefore, the coupler stops in about one second. When accelerating in the opposite direction to about 10 m / s, the same acceleration of about 10 m / s ² is used, which takes another second. Therefore, in this embodiment, the couplers M and N move the cars B and A in at least 2 seconds. At 10 m / s, the vertical section of the loop 330 is 20 m long. In addition, the loop allows the couplers M and N to decelerate to a stop and to accelerate (clockwise) to the opposite side so that the next pair of cars can be carried. Must be long enough. About 10m / s to about 10m
A deceleration of / s ² requires a distance of 5 m, which is the same when re-acceleration. Therefore, in order to carry the car, an extra 10 m is required from the above 20 m. The working space for the movement of the coupler M and the coupler N is thus 30 m in this embodiment (or it is appropriate to use a slightly longer distance). When the coupler X and the coupler Z move a distance larger than 30 m, they are of course typically 250 to 250 in FIG.
Although it is possible to travel 300 meters, the coupler M and the coupler N pause so as to wait for another pair of cars approaching for a predetermined time. Before these are accelerated, acceleration is performed so as to synchronize with the approaching car. In the embodiment of FIG. 23, the time during which the couplers X and Y do not actually move their cars is the start or end of acceleration in each traveling. Therefore, if a large number of coupler segments with ropes (ie, P to U) having intermediate loop shuttle segments (ie, V, VV) are used, the elevator core space always has a plurality of upward and downward hoistways. Since the car can be moved, it is possible to make the most effective use.

FIG. 24 shows a schematic embodiment of FIG. 23, in which the segments P, Q,. . . Each run of U takes place over a distance of 250 m, each overlapping each other in loop shuttle sections V, VV.
Each segment P, V, Q,. . . U accelerates / decelerates without mounting a car. This measure requires less traction, because it depends solely on the weight of the coupler. On the other hand, it can be mentioned that less force is required to accelerate and decelerate. As seen in FIG. 23, the segment V is a closed loop, and the idle sheave 331 has a downward force applied thereto, which is indicated by the arrow in FIG. This downward force is applied by a weight or a spring. This improves traction when there is no car supported by each of the couplers M and N. In a similar manner, the couples of couplers W, X or Y, Z have their bottoms roped together to idle sheaves, whereby a downward force is applied to the sheaves 331. Same as in the case.
Further ropes can also be added, as usual, as compensating ropes. However, normally, this compensating rope is not required. Similarly loop 330
May be simply a single rope spanned by a sheave between the two couplers, which is shown in FIG.
In the sector Q.

When the car is connected to another car, the landing shuttles 340 and 341 may be used to prevent deceleration or acceleration during landing. Referring to FIGS. 25 and 26, the landing shuttles 340, 341 are used to stop the car during landing and to accelerate the car from landing, with each landing being at each end. The portion is provided with a coupler 342. The coupler 342 has a number of tooth shapes 343 and is arranged like the tooth 48 on the couplers W to Z (FIGS. 8 and 9). The coupler 342 is adapted to selectively protrude or retract the teeth on one side as in FIGS. 8 and 9, and the teeth 50 of the coupler 41 mounted on either side of the shuttle. To be connected to. The coupler is moved up and down by LEM means 344, which in this case can also be an active magnetic guide which eliminates the need for guide rails and rollers. Each LEM means 344 is comprised of four LEM primary portions 345, each of which is orthogonally disposed with respect to another primary portion 345 and is secured to one of the paired hoistway frame members 346. (Only shown in FIG. 25). Also, any other suitable structure can be secured. The coupler 342 has a U-shaped bracket 350, and the bracket 350 is a permanent magnet LEM.
It has a secondary portion 351. Bracket 3 above
50 can be held on the coupler 342 by bolts 353, or can be held by other suitable means.

In operation, the shuttles 340, 341
One of them is at the exit of landings 32, 33, which are adapted to accelerate the car to the speed of the segment. When the car overlaps the couplers W-Z, the car is connected to it, after which the shuttles 340, 341 are decelerated, stopped, returned in the opposite direction, and wait. . When the car approaches, the shuttles 340 and 341
The car is accelerated and connected to the car, which is disengaged from the segment, after which the shuttle decelerates to transport the car to the landing stop for loading. The LEM 344 of the coupler is made strong (or large) enough to support the imbalanced weight of the car and passengers.

The shuttles 340 and 341 can be arranged so as to be straight with the segment V so as not to interfere with each other as shown in FIG.

The embodiments described so far have described elevator car doors at the front and rear of the car. As mentioned above, if the shuttle 39 is located within the loop, rather than outside the loop, it is necessary to provide a coupler on only one side of each car. In such a case, the car door would be located on the opposite side of the coupler (on the opposite side of the rope loop). In this case, different landing arrangements can be used, as shown in FIG.
7. In this figure, the above-mentioned get off lobby 3
20, 321 and the boarding lobbies 322, 323 are provided not on the ends of the landing area but on the sides of the landing area. This makes it easier to remove, rotate and attach the car and return it to the hoistway. A simple turntable 325 can be used to rotate the car, and a similar jack 250 that supports the car when riding or dismounting from the turntable.
(Shown by small white or black circles) can also be provided.
The rotation of the car E is performed as shown in FIGS.

The present invention can be used for a multi-deck car. All of the co-pending applications mentioned above may also be referenced in this application.

Although the present invention has been described with reference to the typical embodiments, those skilled in the art will recognize that various modifications, exclusions, and additions made so far can be made within the spirit of the present invention. Obviously you can do that.
