Description

  Embodiments of the present invention relate to an elevator including a car in which passengers enter and leave the hall.

  Conventionally, in a station installed in a deep underground, a means for a train passenger to move between the ground and the station has been mainly an estimator and a staircase. For this reason, since the number of installed elevators is small and the elevator car has a small capacity, it is rare to use the elevator. Moreover, when an elevator is installed, it is often installed for the purpose of barrier-free and not intended for high-speed movement.

JP 2012-148876 A JP-A-4-350084

  At a station installed in such a deep underground (hereinafter referred to as a deep underground station), a large number of escalators or climbing stairs are required before entering the ticket gate floor or the ground. This takes considerable time and effort for the passengers. Moreover, when a passenger has a large baggage, it is necessary to consider prevention of slipping when placing the baggage on an escalator, and this is not recommended by escalator manufacturers.

  The elevators installed in such deep underground stations are installed so that wheelchair users are not inconvenienced, and the number of installations is limited to one in one place, and the car size is also the minimum It is often the size of.

  Furthermore, when paying attention to the station structure, the vertical flow line from the deep underground station to the ticket gate floor or the ground is based on the installation of es-strators, so it is also deployed in the horizontal direction, increasing the distance traveled by the user. The travel time is getting longer. When the s-force generator is the main line of motion, the standard speed is 30 m / min and the vertical speed is 15 m / min at an inclination angle of 30 degrees. As you can see, there is not much attention on the underground movement speed.

  Recently, the opening schedule of the Central Linear Shinkansen has been materialized, but for users of the Linear Shinkansen, even if the travel time on the train is shortened, the access time before and after getting off the train has become longer. Greatly reduces the benefits obtained.

  This invention is made | formed in view of the said subject, and makes it a subject to provide the elevator which can transport a large capacity | capacitance number of persons more quickly in space saving.

  The elevator which concerns on embodiment of this invention is an elevator provided with the cage | basket | car which a passenger enters / exits between landings. This elevator is provided with a door pocket for a car door of a car at a predetermined midway position of the car frontage. And the car door which can be accommodated in a door pocket is each provided in the left-right side of a door pocket, and the entrance of two places on either side is provided in the same surface of a car frontage.

  Hereinafter, an elevator according to an embodiment will be described with reference to the accompanying drawings. In the second and following embodiments, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[First Embodiment]
First, the first embodiment will be described. As shown in FIG. 1, the elevator E of the present embodiment includes a car 1 that moves up and down in the hoistway 3 and allows passengers to enter and exit from the landing. A door pocket 4 for the car door of the car 1 is arranged at a predetermined midway position J of the car front door A (the width of the car room as viewed from the front side of the car).

  Here, the predetermined midway position J is a position where the ratio of the entrance / exit entrance to the car entrance can be increased as compared with the conventional case. In the present embodiment, the predetermined midway position is set to the center position M of the car frontage A so as to be most efficient in terms of widening the entrance / exit frontage, the center position in the width direction of the door pocket 4 and the center position of the car frontage A. M matches. The width of the door pocket 4 is (1/5) A, which is one fifth of the car frontage A.

  Car doors (door panels) 2a, 2b and car doors 2c, 2d that can be stored in the door bag 4 are provided on the left and right sides of the door bag 4, respectively, and two left and right doorways 6a, 6b is arranged. With this configuration, both the left and right sides of the door bag 4 are two-door single door cage doors.

  In the present embodiment, the car front A is larger than the depth length B of the car room S.

  In the present embodiment, the car doors 2a to 2d are overlapped in the boarding / alighting direction (the direction perpendicular to the car frontage) at the position of the doorcase 4 when the door is opened, thereby eliminating the door pocket protruding outside the car frontage A and the car. The ratio of the entrance / exit entrance to the entrance A (the total value of the width (2/5) A of the entrance / exit 6a and the width (2/5) A of the entrance / exit 6b) can be increased to (4/5) A. . Therefore, it is possible to provide an elevator E that saves space and can greatly reduce the time required for passengers to get on and off.

  Moreover, since each car door is arrange | positioned at the right-and-left both sides of the door pocket 4, it becomes the structure of a two-door single-opening in the right-and-left both sides of the door pocket 4 (a door opening shows the door opened only to either right or left). Therefore, the open / close mechanism of the car doors 2a to 2d can be simplified as compared with the case of four doors with one door.

  Moreover, since the car front A is made larger than the depth length B of the car room S, it is easy to take a wide entrance / exit.

  Such an elevator E is used to transport passengers using trains, etc., between stations installed deep underground and floors such as ticket gates installed on or near the ground. It is effective as a space-saving elevator with a function of a large-capacity shuttle for moving faster between the ticket gate floor and the home floor.

  And for a high-speed railway user, there is a great effect in moving in a shorter time. This technology can be applied not only to the basement but also to high-rise buildings, and it is possible to shorten the time of access with a space-saving large-capacity elevator.

(Comparative study example 1)
As shown in FIG. 14, the elevator of Conventional Example 1 is a four-door centrally opened elevator. The center opening is a door that opens from the center to the left and right objects, and a door in which the left and right door panels overlap each other is called a four-door center opening. In general, the four-door central opening is usually used for a car with a wide frontage. It is also said to be a four-door double door.

  In the elevator of Conventional Example 1, when the entrance / exit opening 86 is to be maximized with respect to the car entrance A, the car doors 82a to 82d project from the car entrance A to the outside of the car entrance. Explaining in detail, in order to maximize the entrance / exit entrance, the center of the four doors will be opened, and the car entrance A is projected on both sides by a quarter, that is, the length of (1/4) A Now overhang to the left and right sides. Corresponding to this overhang, it is necessary to make the width W of the hoistway 83 wide (if the entrance entrance is 4 m, the car door will protrude 1 m to the left and right sides of the car when the door is opened. , A large dead space is created in the hoistway and becomes inefficient).

  In contrast, in the first embodiment, since the car doors 2a to 2d are all stacked at the position of the door pocket 4 when the door is opened, there is no need to provide a door pocket projecting outside the car front door A. The ratio of can be increased. Therefore, the space-saving hoistway 3 having a dimension in which necessary equipment such as the guide rail R can be accommodated in the hoistway can be obtained, and the space-saving elevator E in which the width of the hoistway 3 is significantly reduced can be obtained.

(Comparative study example 2)
As shown in FIG. 15, the elevator of Conventional Example 2 is a four-door central opening (2CO) elevator. As shown in FIG. 16, the elevator of Conventional Example 3 is a three-door single door (3S) elevator. Conventional examples 2 and 3 are examples in which the car door does not protrude outside the car front A.

  In the first embodiment and the conventional examples 2 and 3, when comparing the entrance / exit entrance when the car entrance is set to the same value (A), the size of the entrance / exit entrance is in the order of the first embodiment (5 minutes of the cage entrance). No. 4), Conventional Example 3 (3/4 of the car frontage), and Conventional Example 2 (4/6 of the car frontage), and the first embodiment can take the widest entrance / exit frontage. Since the entrance / exit time can be shortened as the entrance / exit opening widens, the first embodiment is more advantageous than the conventional examples 2 and 3 in terms of shortening the entrance / exit time. In particular, since an elevator installed in the basement or station platform is required to save space, the ability to make the hoistway width smaller is a great advantage.

[Second Embodiment]
Next, a second embodiment will be described. As compared with the first embodiment, the elevator according to the present embodiment includes a monitor unit 10 and a monitor unit 10 for measuring the number of passengers in the hall F and the number of passengers in the car 1, respectively, as shown in FIGS. The number of passengers at the hall F and the number of passengers in the car 1 are received, the congestion situation is judged according to the recognized number of passengers, and the passenger guidance form at one doorway and the other doorway And a guiding means 12 for guiding a passenger at one of the entrances 6a and the other entrance 6b in the passenger guidance form selected by the judging means 11. A function as a congestion state detection device is obtained by the measurement by the monitor means 10 and the grasp of the number of passengers by the judgment means 11.

  As shown in FIGS. 5 to 8, the monitor means 10 is composed of, for example, a car camera 10k that photographs the car room S from the car ceiling and a hall camera 10n that photographs the hall F from the ceiling. The Note that it is possible to provide a monitor other than the camera (sensor or the like) as the monitor means 10.

  The judging means 11 is provided, for example, in an elevator control panel.

  As the guide means 12, for example, display panels 15a and 15b on the upper side of the door for displaying the direction of passengers in the car 1, display panels 16a and 16b on the floor, and a door for displaying the direction of passengers on the landing F side. Upper display panels 17a and 17b, display panels 18a and 18b on the floor, an announcement device 13 that provides voice guidance within the car 1, and an announcement device 14 that provides voice guidance on the hall F side are disposed. Each display panel is displayed on a liquid crystal display, for example.

  In the present embodiment, using the fact that the entrances are arranged on the left and right sides of the car 1, respectively, the entrances are properly used as follows.

  First, it is determined by the determination means 11 (congestion state detection device) whether or not the inside of the car 1 is congested (step S1). In the case of Yes in step S1, the determination means 11 determines that the car 1 is “crowded” and moves to step S2. Yes in step S1 is when a preset congestion value is detected (for example, when more than half of the passenger capacity of an elevator is detected).

  In the case of No in step S1, the determination unit 11 determines that the car 1 is “free” and moves to step S6 described later.

  In step S2, the judging means 11 judges whether or not the hall F is congested. In the case of Yes in step S2, the determination means 11 determines that the landing F is “congested” and moves to step S3. Yes in step S2 is the same as in step S1 when a preset congestion value is detected (for example, when more than half of the passenger capacity of the elevator is detected at the landing F). is there.

  In the case of No in step S2, the determination unit 11 determines that the landing F is “free” and moves to step S6 described later.

  In step S3, the determination means 11 determines one doorway 6a on the getting-off side and the other doorway 6b on the boarding side. In this case, the judging means 11 may appropriately determine which exit / exit is the exit side or the boarding side. In step S3, it is determined that both the car 1 and the landing F are “congested”.

  Then, the car 1 stops on the destination floor (step S4), and guidance display and voice guidance are performed (step S5).

  In the guidance display in the car 1, for example, as shown in FIG. 5, "exit" is displayed on the display panel 15a on the upper door side on one doorway 6a side, and the advancing direction mark MA is displayed on the display panel 16a on the floor. Is displayed. Then, on the other entrance / exit 6b side, “entrance only” is displayed on the display panel 15b above the door, and an entry prohibition mark MP is displayed on the display panel 16b on the floor. In the voice guidance in the car 1, the announcement device 13 arranged in the car broadcasts that the user gets off from the other entrance 6b without getting off from the other entrance 6a.

  In the guidance display at the landing F, for example, as shown in FIG. 7, on one side of the entrance / exit 6a, “exit only” is displayed on the display panel 17a above the landing door and the entry prohibition mark MP is displayed on the display panel 18a on the floor. Is displayed. On the other entrance / exit 6b side, “entrance” is displayed on the display panel 17b on the upper side of the landing door, and the advancing direction mark MA is displayed on the display panel 18b on the floor. In the voice guidance of the hall F, the announcement device 14 arranged at the hall F is broadcast so as to get on from one entrance 6a and not from the other entrance 6b.

  By guiding the passengers in the car and on the landing side in this way, even when it is congested, as shown in FIG. And the time it takes to get on and off is greatly reduced. In addition, in Fig.4 (a), you may make it the reverse direction D2 which shows a passenger's flow line with a dashed-two dotted line.

  As described above, in the case of No in step S1, the determination unit 11 determines that the car 1 is in a quiet state and moves to step S6.

  In step S6, the determination means 11 determines that there is not much time difference even if the passengers freely enter and exit, and displays it so that the passenger can get on and off at both the entrances 6a and 6b. In the guidance display in the car, for example, as shown in FIG. 6, in the car, on the display panel on the upper side of the door, “exit” is displayed at both the entrances 6a and 6b, and in the guidance display at the landing F. For example, as shown in FIG. 8, “entrance” is displayed at both the entrances 6a and 6b. Further, on the display panel on the floor, the advancing direction mark MA is displayed at both the entrances 6a and 6b on both the inside of the car and the landing side.

  Then, the car 1 stops on the destination floor (step S7), and guidance display and voice guidance are performed (step S8).

  By guiding the passengers in the car and on the landing side in this way, as shown in FIG. 4 (b), it takes less time to get on and off even when the passengers can freely enter and exit.

  As described above, according to the present embodiment, in addition to the effects achieved in the first embodiment, it is possible to greatly reduce the boarding / alighting time during congestion, and to allow passengers to freely enter and exit during quiet periods. However, there is an effect that it does not take time to get on and off.

  In steps S1 to S8, the order can be changed as appropriate. For example, step S1 and step S2 may be interchanged.

[Third Embodiment]
Next, a third embodiment will be described. In the present embodiment, as shown in FIG. 9, each car door has an L shape in plan view as compared with the first embodiment. Two car doors 22a and 22b are provided on one side of the door pocket 24 arranged in the center of the car frontage, two car doors 22c and 22d are provided on the other side, and two doors are opened on both sides. It has become.

  As shown in FIG. 9A, each of the car doors 22a to 22d has a bent portion L bent in an L shape toward the landing side on the side far from the door pocket 24 arranged in the center of the car frontage. It continues to the panel part G.

  When these car doors are stored in the door pocket 24 as shown in FIG. 9 (b), as shown in FIG. 9 (c), the rectangular area 22br occupied by the car door 22b and the car door 22c are viewed in plan view. The rectangular area 22cr that occupies is partially overlapped in the getting-on / off direction. Similarly, the rectangular area of the car door 22a and the rectangular area of the car door 22d are partially overlapped in the getting-on / off direction in plan view. Yes.

  According to the present embodiment, in addition to the effect achieved in the first embodiment, there is also an effect that the door pocket 24 can be thinned (the thickness d of the door pocket 24 can be reduced). And by such thinning, the capacity | capacitance of a cage | basket | car can be enlarged greatly, without increasing car depth length B (refer FIG. 1) and hoistway depth length C (refer FIG. 1).

[Fourth Embodiment]
Next, a fourth embodiment will be described. In the present embodiment, components having the same functions as the components described in the third embodiment will be described with the same reference numerals as appropriate even if the shapes and the like are slightly different.

  As shown in FIGS. 10 to 13, in the present embodiment, the L-shaped car door 22 d and the car door 22 c in a plan view are arranged so that the inner sides of the door face each other, and a door mechanism for driving the door. 26 is arranged in the door inner space. In the present embodiment, a rack and pinion mechanism is disposed as the door mechanism 26. Since the configuration is the same on the other side of the door pocket 24, the door mechanism on one side of the door pocket 24 will be described in detail below, and the detailed description of the door mechanism on the other side will be omitted.

  10 and 11, a high speed door hanger rail 25d that supports a car door 22d (a car door that opens and closes an entrance / exit part far from the door bag 24, and hereinafter referred to as a high speed door 22d), and a car door The hanger rail 25c for the low speed door that supports the door 22c (which is a car door that opens and closes the entrance / exit part close to the door pocket 24 and is referred to as a low speed door 22c in the present embodiment) overlaps in plan view (projection surface in the vertical direction). Are installed).

  As shown in FIGS. 10 to 13, the pinion (pinion gear) 30 of the high speed door 22 d and the pinion 31 of the low speed door 22 c are connected by a drive transmission belt 32. At this time, as shown in FIG. 12, the drive transmission belt 32 is connected so that the high speed door 22d and the low speed door 22c move in the same direction.

  Here, the racks (rack gears) 28 and 29 are fixed to the high-speed door 22d and the low-speed door 22c, respectively, but the pinions 30 and 31 need to be attached to the car side so as to be stationary. As shown in FIG. 11, it is desirable that the pinions 30 and 31 be as close as possible with the drive transmission belt 32 interposed therebetween because the door mechanism 26 can be made thinner. In the present embodiment, the door mechanism 26 is a door that moves the low-speed door 22c following the high-speed door 22d by transmitting a moving force to the high-speed door 22d inside the door of the low-speed door 22c and inside the door of the high-speed door 22d. It is arranged as a mechanism.

  In the door drive device 40, the rack 28 fixed inside the high speed door 22d rotates the pinion 30 on the high speed door side fixed on the car side, and the pinion 30 on the high speed door side is driven at a low speed by the drive transmission belt 32. The pinion 31 on the door side is rotated, and the pinion 31 on the low speed door side moves the rack 29 fixed inside the low speed door. Thus, the low-speed door 22c is driven and driven by driving the high-speed door 22d for both opening and closing. Therefore, it is not necessary to employ a configuration in which both the high-speed door and the low-speed door are directly driven as in the prior art.

  As described above, in the present embodiment, the high-speed door hanger rail 25d and the low-speed door hanger rail 25c are arranged in two stages up and down so as to overlap in plan view. Two door panels (the high-speed door 22d and the low-speed door 22c) provided at the same doorway are hung so as to partially overlap the high-speed door hanger rail 25d and the low-speed door hanger rail 25c. . Therefore, the effect of thinning the door pocket 24 by overlapping the rectangular regions as described in the third embodiment is obtained in addition to the effect exhibited in the first embodiment.

  In addition, the effect of thinning the door pocket 24 by thinning the door mechanism 26 is also obtained. A door mechanism 26 that moves the low-speed door to follow the high-speed door by transmitting the moving force to the high-speed door is arranged inside the low-speed door and inside the high-speed door. Since it is not necessary to drive, the effect of further reducing the thickness can be obtained.

  Although some embodiments have been described above, these embodiments are presented as examples, and the scope of the invention is not intended to be limited to them. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
