Description

  The present invention relates to an elevator car sill relay device having a function of maintaining a gap between a car sill and a landing sill as usual during normal traveling of an elevator car and narrowing the gap when landing.

  Conventionally, in general elevators, when the car is moved up and down in the hoistway and landed on the registered floor and the car door and the landing door open, the space between the car sill and the landing sill is designed. A gap of 20 mm to 30 mm is generated above. However, there is a problem that this gap often becomes an obstacle, causing troubles such as tripping a foot when a passenger who is a user gets on or off, or a wheel of a cart or a wheelchair being caught.

  Therefore, a technique for solving such a problem has also been proposed. As a well-known technique, the gap between the car sill and the landing sill can be narrowed during normal operation, and the car sill can be used during firefighting operation. "Elevator car sill" (see Patent Document 1) that can widen the space between the landing sills, "Elevator sill gap closing device" that allows cars such as carts and wheelchairs to get on and off the car smoothly. (Refer to Patent Document 2), “Elevator sill gap closing device” (refer to Patent Document 3) preferable for space saving of hoistway.

  The technique of Patent Document 1 described above includes a main body portion fixed to the car and a tip portion that is supported by the main body portion and faces the landing sill, and the tip portion faces the landing sill and the landing sill. Fire-fighting operation is supported by the main body part so that it can take a separated state (one side of the hinge having a support shaft is attached to the bottom of the main body part and the other side of the hinge is attached to the tip part) In this case, the gap between the car sill and the landing sill is widened so that the interlock roller and the car sill provided on the landing door can freely move up and down without interfering with each other. is there. In the case of such a structure, the tip part is fixed with bolts by the flange of the main body part during normal operation, so if it is assumed to be applied to a high-speed elevator in a high-rise building, installing a fixed type sill will reduce the wind Since there is concern about the generation of sound, there is a problem that it is unsuitable.

  Moreover, the technique of patent document 2 is comprised from the movable member which the cage | basket | car side sill of an elevator fits to the front end of the fixed member, and when the doorway is fully closed, the tread of the movable member inclines toward the front downward of the fixed member On the other hand, the movable member slides forward along the tread surface of the fixed member during the door opening operation to close the gap between the car side sill and the landing side sill. In the case of such a structure, the movable member has a thin portion and is supported by the fixed member in a state where the space portion is formed at the time of sliding, so that the mechanical strength is not sufficient, and when a heavy object is placed on the carriage If there is an external force applied due to such a heavy load or an earthquake, deformation is likely to occur, in which case there is a possibility that the gap may not be sufficiently closed without sliding smoothly, so there is a problem in durability .

  Furthermore, in the technique of Patent Document 3, a slide block disposed along a gap between a car side sill and a landing side sill is connected to a car side door via a bracket, and the slide block is fully closed at the car side entrance / exit. Sometimes it is located closer to the door closing direction of the car side door than the engagement plate and the engagement block in the gap, but at the time of door opening operation, it is displaced in the door opening direction together with the car side door and the gap is widened across the entrance / exit width It is the structure which obstructs over. In the case of such a structure, the number of parts is large and the installation work is complicated and the cost is likely to be high.In addition, even if the slide block and the engagement block do not interfere when the car door is fully closed while the car is running, Since it is necessary to provide each member in advance, if application to a high-speed elevator is assumed, there is a problem that wind noise is likely to occur as in the case of Patent Document 1, which is not suitable.

  In short, assuming application to high-speed elevators in modern high-rise buildings, the normal floor space is maintained by maintaining the gap between the car sill and the landing sill as usual during normal elevator traveling. In order to prevent wind noise, the structure of Patent Document 1 in which the clearance is narrowed somewhat by providing a clearance rather than the structure that completely closes the gap as in Patent Document 2 and Patent Document 3 when landing on the floor. For this reason, there is a demand for the development of a car sill-spanning device using a movable sill that narrows the gap.

  The present invention has been made to solve such problems, and its technical problem is to reduce the gap between the car sill and the landing sill with a simple structure when landing the car. It is an object of the present invention to provide an elevator car sill relay device having a function of opening a gap during up-and-down traveling and having high durability and applicability.

  In order to solve the above technical problem, the present invention is arranged at the bottom of a car sill of an elevator car and interlocks with the fully opening operation of the car door when the car is landed on the registered floor. In an elevator car sill intermediary device equipped with a movable sill that narrows the gap between the car sill and the landing sill, the movable sill rotates when the car lays down and the car sill The tip portion extending along the gap enters the gap to narrow the gap, and rotates in conjunction with the fully closing operation of the car door when the car is moving up and down, so that the tip part is retracted from the gap. It is a rotary structure that opens the gap.

  According to the elevator car sill relay device of the present invention, with the above-described configuration, the tip of the movable sill of the rotary structure enters the gap between the car sill and the landing sill only when the car is landing. Narrowing the gap, and the ability to retreat and open the gap when the car is moving up and down, the durability and applicability are increased with a simple structure, and it can be used for wheelchair users and general users. The safety and convenience when getting on and off are remarkably improved, and wind noise is reduced even when the car is moved up and down at a high speed. Therefore, application to a high-speed elevator is preferable.

FIG. 4 is a side cross-sectional view of the main components in the vicinity of the car entrance 1 when the car is moving up and down in the direction of arrow AA in FIG. FIG. 5 is an enlarged view of the fixing structure of the shaft portion of the movable connecting sill 12 in the region E in FIG.

  Referring to FIG. 3, in the car sill relay device according to the embodiment, the tip of the movable sill 12 abuts the car sill 8 along the car sill line L when the car lands. In addition to being connected to the car sill 8, a predetermined clearance 10 is provided between the platform sill 9 and the gap 11 being narrowed. Here, the stability of the mechanical strength is secured by positioning the distal end of the movable connecting sill 12 connected to the car sill 8, and the clearance 10 is provided between the landing sill 9 and the distal end. Entry into the gap 11 is smoothly performed. The movable connecting sill 12 itself has a substantially L-shaped cross-section in the side direction, and a fixed portion for the shaft in which the middle part of the substantially L-shaped long arm piece is installed at both ends of the bottom of the car sill 8. The rotary shaft 15 pivotally supported by the member 13 is attached to each of the outer ends of the rotary shaft 15, and a substantially L-shaped short arm piece has a tip. If the movable connecting sill 12 has such a shape and structure, it is easy to process and manufacture during manufacturing.

  The movable connecting sill 12 is pivotally supported at a predetermined position near the short arm side of the substantially L-shaped long arm piece, and the other end side of the drive rope 6 with respect to the free end on the other end side. A pin that is fastened (the drive rope 6 itself is bridged over the drive pulley 5 attached to the rail frame 3 above the car door 7 and fixed at one end to the door hanger 4 as described with reference to FIG. 1) 14. In the car sill intermediary device having such a configuration, the drive rope 6 is interlocked with the opening / closing operation of the car door 7 driven by the car door opening / closing device 2 provided on the rail frame 3, and is specifically shown in FIG. 3. As the drive rope 6 is pulled up when the car door 7 is fully opened at the time of landing, the tip of the movable connecting sill 12 is pulled up via the pin 14 and enters the gap 11. Further, the tip of the movable connecting sill 12 is lowered via the pin 14 along with the fishing of the drive rope 6 when the car door 7 is fully closed during the up-and-down traveling shown in FIG. With the side walls of the L-shaped long arm pieces engaged with the stoppers 16 provided at both ends of the car sill 8, the tip ends retract from the gap 11 to open the gap 11. Incidentally, in a state in which the distal end portion of the movable connecting sill 12 is retracted from the gap 11 and is locked by the stopper 16 and the movable connecting sill 12 main body is positioned, the movable connecting sill 12 is moved as shown in FIG. The front end portion is set so as not to protrude from the car sill line L to the landing sill 9 side. In the car sill sill relay device having such a structure, the movable sill 12 can be easily turned into a rotary structure by using existing parts.

  Further, referring to FIG. 5, here, the structure of the shaft portion is fixed by omitting the constituent part of the long tip portion extending in the direction along the car sill 8 of the movable connecting sill 12 main body of the rotary structure. Is shown. In this fixing structure of the shaft portion, the rotating shaft 15 is moved outwardly in the direction of closing the car door 7 interposed between the other inner side end of the rotating shaft 15 and a fixing member 17 provided at the bottom of the car sill 8. A spring 18 is attached for biasing. The urging force of the spring 18 acts in the direction in which the car door 7 is closed, thereby supporting the operation in which the movable sill 12 is lowered downward by the fully closing operation of the car door 7 when the car is moving up and down. In addition, it also serves to suppress the force from acting on the upper side by mistake.

  In the elevator car movable connection sill according to the above-described embodiment, the car is arranged at the bottom of the car sill 8 and interlocked with the fully opening operation of the car door 7 when landing on the registered floor. With respect to the movable connecting sill 12 that narrows the gap 11 between the sill 8 and the landing sill 9, the tip extending along the car sill 8 enters the gap 11 to have a clearance 10 when the car lands. In this way, a rotary structure is adopted in which the gap 11 is narrowed and rotates in conjunction with the fully closing operation of the car door 7 when the car is moving up and down, and the front end portion is retracted from the gap 11 to open the gap 11. As a result, the tip of the movable connecting sill 12 enters the gap 11 between the car sill 8 and the landing sill 9 only when the car is landing, narrows the gap 11, and retreats when the car moves up and down. Since the function of opening the gap 11 is obtained, durability and applicability are increased with a simple structure, and the safety and convenience when getting on and off the car for wheelchair users and general users are greatly improved. Since wind noise is reduced even when the car is traveling up and down at high speed, application to a high-speed elevator is suitable.

  In the elevator car movable sill according to the embodiment, the movable sill 12 is fixed to the inner end of the rotary shaft 15 and the bottom of the car sill 8 as described in FIG. Although the example in which the spring 18 is interposed between the fixing member 17 provided has been described, an urging member such as an accordion member that urges the rotating shaft 15 outward can be applied in addition to the spring 18. Therefore, the elevator car movable joint of the present invention is not limited to the form disclosed in the embodiments.
