Description
Technical Field
An embodiment of the present invention relates to an elevator apparatus having a blocking structure for a gap generated between doorsills provided on a waiting hall side and a car side with respect to an entrance portion of a car.
Background
In an elevator apparatus in which a car installed in a hoistway of a building ascends and descends between floors to transport people or goods, a certain gap is provided between a waiting hall and the car at each floor in order to ascend and descend the car. Therefore, when the car stops at the waiting hall and the doors of the doorway are opened, a gap is formed between the doorsill on the waiting hall side and the doorsill on the car side. The gap between the sills is dangerous because a person falls down or a wheel of a wheelchair, a dolly, or the like gets caught. Further, small articles such as keys and cards may fall into the pit through the threshold gap and be difficult to collect.
Therefore, conventionally, there has been proposed an elevator apparatus in which a blocking member for blocking a gap between the threshold is provided and the elevator apparatus is operated to block the gap between the thresholds when the door is opened (see, for example, japanese patent application laid-open No. 2009-286504).
In the prior art, a pickup plate (blocking member) for blocking a threshold gap is provided at a lower portion of a car floor, and the threshold gap is blocked when an elevator door is opened, thereby preventing an article from falling into a hoistway from the threshold gap. That is, the pickup plate is accommodated in a pickup plate accommodating portion formed below the car side sill during traveling of the car, and the pickup plate is extended by an actuator such as an electric motor to close the sill gap in accordance with opening of the door after the car stops.
In such a device, a relatively expensive actuator such as the electric motor must be provided. Further, a sensor or a control circuit for operating the actuator at a predetermined timing is required. Therefore, the structure is complicated, which becomes a factor of failure occurrence, and the cost also increases.
Disclosure of Invention
The invention provides an elevator device which can realize reliable action based on mechanical drive at low cost without using expensive actuator by using a link mechanism mechanically linked with the opening and closing action of a door to perform the action of blocking a gap between a threshold at a waiting hall side and a threshold at a car side.
An elevator device according to an embodiment includes: a car side threshold for guiding a car door provided at an entrance of the car in an opening/closing direction of the car door; doorsills on the side of the elevator waiting hall, which guide elevator waiting hall doors arranged on each layer where the elevator car can stop and corresponding to the entrance and exit of the elevator car along the opening and closing direction of the elevator waiting hall doors; a blocking member having a shape capable of blocking a gap generated between the car side rocker and the lobby side rocker, and capable of sliding between a blocking position for blocking the gap and a retreat position; and a link mechanism coupled to the closing member and capable of engaging with the operating member on the car door side in accordance with an opening/closing operation of the car door, and driving the closing member in a sliding direction by converting a force received from the operating member by the engagement with the operating member into a sliding direction of the closing member, wherein the closing member is coupled to an operating spring receiving a moving force toward the closing position, and when the car door starts a door opening operation from a door closing end, an engaging force between the link mechanism and the operating member on the car door side is released to allow a sliding movement toward the closing position by the operating spring, and the link mechanism engages with the operating member on the car door side in accordance with the movement toward the door closing end, and the moving force received by the link mechanism causes the closing member on the closing position to slide to the retracted position against an elastic force of the operating spring against the moving force of the operating spring .
Another elevator apparatus according to an embodiment includes: a car side threshold for guiding a car door provided at an entrance of the car in an opening/closing direction of the car door; doorsills on the side of the elevator waiting hall, which guide elevator waiting hall doors arranged on each layer where the elevator car can stop and corresponding to the entrance and exit of the elevator car along the opening and closing direction of the elevator waiting hall doors; a blocking member having a shape capable of blocking a gap generated between the car side rocker and the lobby side rocker, and capable of sliding between a blocking position for blocking the gap and a retreat position; and a link mechanism coupled to the blocking member and engageable with an operating member on the car door side in accordance with an opening/closing operation of the car door, the link mechanism converting a force received from the operating member by the engagement with the operating member into a sliding direction of the blocking member to drive the blocking member in the sliding direction, wherein a link of a double-end coupling type is used as a link constituting the link mechanism, the link being rotatably supported at a center portion by a pivot support shaft and having both end portions coupled to other members via a coupling shaft.
According to the above configuration, since the operation of closing the gap between the rocker on the hall side and the rocker on the car side is performed by the link mechanism mechanically linked to the opening and closing operation of the door, an expensive actuator is not required, a reliable operation can be obtained by mechanical driving, and the configuration can be made at low cost.

Detailed Description
Hereinafter, embodiments will be described in detail with reference to the drawings.
First, the overall structure of the elevator apparatus will be described with reference to fig. 1. As shown in fig. 1, an elevator apparatus 1 includes a car 4 and a counterweight 5 disposed in a hoistway 3. A machine room 6 is provided above the hoistway 3, and a hoisting machine 7 for driving main ropes 9, a control device 8, and the like are provided in the machine room 6. The control device 8 is a device that controls the entire elevator apparatus 1, and controls the operation of the hoisting machine 7 in response to a hall call or a car call to stop the car 4 at a floor where the call is made.
Further, the elevator apparatus may be a so-called machine room-less elevator apparatus in which the hoisting machine 7 and the control device 8 are downsized without installing the machine room 6 and installed in the upper portion in the hoistway 3.
In the elevator apparatus 1, a doorway 12 communicating with the car 4 in the hoistway 3 is provided in a waiting hall 11 provided at each floor of the building, and a waiting hall door 2 is provided at the doorway 12. The hoistway door 2 is engaged with a car door 25 provided at the doorway 24 of the car 4 via an interlocking mechanism, not shown, when the car 4 stops, and is opened and closed in conjunction with the opening and closing of the car door 25.
Fig. 2 is a front view of a car door 25 portion provided at an entrance of the car 4 as viewed from the side of the hall 11. The car door 25 is a so-called side-by-side opening type in which two door panels 25a and 25b (only a door stop portion is shown, and other portions are not shown) are opened in different lateral directions from each other. The two door panels 25a and 25b are connected to door opening/closing mechanisms formed on both sides of the doorway 24 of the car 4, and are driven by the door opening/closing mechanisms in the lateral direction of the figure to perform opening/closing operations.
The door opening and closing mechanism is well known and is not directly related to the present invention, and therefore, the structure thereof will not be described, and the two door panels 25a and 25b are driven in the left-right direction along the guide rails by the power of the motor, not shown, so as to be opened and closed.
A car side sill 31 is provided at the doorway portion of the car 4, and guides the two door panels 25a and 25b constituting the car door 25 to be slidable in the opening and closing direction. The car-side rocker 31 is provided at the lower side of the doorway 24 of the car, and guide grooves formed in the upper surface thereof are engaged with the lower ends of the two door panels 25a and 25b, respectively, to guide the two door panels 25a and 25b in the opening and closing direction.
As shown in fig. 6 to 8, a rocker 32 is provided on the side of the waiting hall 11 with respect to the rocker 31 on the car side. The doorsill 32 on the hall side is disposed to face one side surface (left side surface in fig. 6 to 8) of the doorsill 31 on the car side with a predetermined gap therebetween. Guide grooves are also formed in the upper surfaces of the doorsills 32 on the hall side, and guide the hall doors 2 shown in fig. 1 so as to be slidable in the opening and closing directions thereof.
Although not shown, the hall door 2 is a two-door type door having two door panels, and when the car 4 stops at the hall 11, the door engages with the car doors 25 of the car 4 and opens and closes together with the car doors 25 as described above. That is, the waiting hall door 2 is locked in the closed state by the interlocking mechanism not shown when the car 4 does not stop, and when the car 4 stops, the locked state is released by engagement with the engaging member not shown on the car 4 side, and the door 2 is opened and closed together with the car door 25.
When the car 4 stops at a predetermined floor, as described above, a gap shown in fig. 6 to 8 is generated between the car side rocker 31 and the lobby side rocker 32. In the embodiment of the present invention, the closing member 35 is provided to close the gap.
The closing member 35 is divided into left and right parts as shown in fig. 2. The divided portion is a portion where the car side sills 31 and an interlocking mechanism, not shown, provided on the hall side are staggered when the car 4 is lifted and lowered, and is divided so as to allow the interlocking mechanism to pass through with a gap left and right.
When the car 4 stops at the interval of the divided portions, a convex portion, not shown, provided at a corresponding portion of the hall side sill 32 is inserted into the interval, and the interval is substantially closed by the convex portion.
As shown in fig. 6 to 8, the upper surface of the blocking member 35 is located below the upper surfaces of the car side rocker 31 and the hall side rocker 32. The shape is formed to have a size capable of closing the gap between the rocker 31, 32 as shown in fig. 6. That is, the width of the entrance 24 on the car side is slightly larger than the front width of fig. 2 and the width of the gap between the side sills 31 and 32 shown in fig. 6 to 8.
The cross section is formed in a vertically long shape, and a recess 35a is formed in an opposing portion facing the illustrated right side surface of the rocker 32 on the side of the lobby. The recess 35a is provided to avoid the head of a screw 36a provided on the right side surface of the rocker 32 provided on the lobby side. The screws 36a are used to perform mounting of the plate 36 that partitions the lower interlayer space. Further, a chamfer 35b is formed at an upper corner of the plug member 35.
The closing member 35 may be made of metal or resin, but a resin material may be used in consideration of workability, cushioning properties with other members, and the like.
The blocking member 35 is configured to be slidable between a blocking position at which the gap between the threshold 31 and 32 is blocked as shown in fig. 6 and a retracted position at which the lower portion of the threshold 31 is retracted to the car side as shown in fig. 7 and 8 (fig. 8 is a view in which parts are removed from fig. 7 to facilitate viewing of the state of the blocking member 35 at the retracted position). Further, the link mechanism 41 described later is slidably driven between the aforementioned blocking position and the retracted position in accordance with the opening and closing operation of the car door 25.
The closing member 35 is attached to a bracket 51 provided on the link mechanism 41 side via a leaf spring 52. The link mechanism 41 is configured to be engageable with an operation member 42 on the car door 25 side as shown in fig. 3 in accordance with the opening and closing operation of the car door 25. Further, the force received from the actuating member 42 by the engagement with the actuating member 42 is converted into the sliding direction of the closing member 35, and the closing member 35 is driven in the sliding direction.
In this embodiment, the link mechanism 41 includes 4 links 46, 47, 48, 49 and a bracket 51 rotatably coupled to each end of the links via a coupling shaft 50, as shown in fig. 4 and 5. The 4 links 46, 47, 48, 49 are rotatably supported by a support member 44 provided on the car 4 side via a pivot shaft 45.
The inner links 47 and 48 among the 4 links are links for coupling drive, and the other ends thereof are coupled to a coupling rod 55 via a coupling shaft 54. A tension spring 56 is provided between the illustrated right end of the connecting rod 55 and the support member 44 in a tensioned state, and applies a force to the link mechanism 41 in a direction to move the bracket 51 in parallel toward the support member 44.
The base end portion of the rod 58 is integrally attached to the pivot shaft 45 of the link 46 constituting the link mechanism 41. An operation pin 59 is provided upright at the tip end of the lever 58. As shown in fig. 3, the upper side surface of the operating pin 59 is arranged to be engageable with an operating member 42 integrally provided on the door panel 25a side of the car door 25. That is, the operating pin 59 abuts against and engages with the operating member 42 when the car door 25 is opened to a predetermined open position, and rotates the lever 58 and the pivot shaft 45 integrated therewith counterclockwise as viewed in the figure.
By this rotation, the other links 47, 48, 49 connected via the link 46 and the bracket 51 integral with the pivot shaft 45 also rotate counterclockwise in the drawing against the tension of the tension spring 56. By the operation of the link mechanism 41, the holder 51 and the closing member 35 supported by the upper portion of the holder 51 via the leaf spring 52 are extended from the retracted position shown in fig. 4, 7, and 8 to the closing position shown in fig. 5 and 6.
Here, the aforementioned tension spring 56 is finally coupled to the closing member 35 via the link mechanism 41, the bracket 51, and the like. The tension spring 56 applies a force to the blocking member 35 via the link mechanism 41 in a direction to return to the retracted position shown in fig. 4, 7, and 8. Therefore, the tension spring 56 functions as a return spring (hereinafter referred to as a return spring 56) for returning the blocking member 35 to the retracted position.
As described above, when the car door 25 is opened to the predetermined open position in the link mechanism 41, the operating pin 59 of the link mechanism 41 engages with the operating member 42 on the car door 25 side as shown in fig. 3, receives a moving force in the opening direction of the car door 25, and slidably moves the blocking member 35 located at the retracted position to the blocking position against the elastic force of the return spring 56.
As shown in fig. 6 to 8, the stopper 61 for stopping the closing member 35 at the closing position and the retracted position with respect to the above-described sliding movement is provided on the support member 44. Fig. 9 shows the stopper 61 partially removed. The stopper 61 has a U-shaped member fixed to the support member 44, cushioning members 62 such as rubber are provided on both inner side surfaces thereof, and an L-shaped contact member 63 having a cross section and extending from the bracket 51 on the closing member 35 side is disposed therebetween.
According to this configuration, the abutting members 63 extending from the bracket 51 abut against both inner surfaces of the U-shaped member of the stopper 61, whereby the sliding movement of the blocking member 35 can be accurately stopped at the blocking position and the retracted position. Further, the cushion member 62 such as rubber may be provided on either one or both of the stopper 61 and the contact member 63.
Of the pivot shafts 45 constituting the link mechanism 41, the pivot shaft 45 integrated with the lever 58 disposed at the right end in fig. 2 and 3 is a rotary shaft that rotates by the engagement of the operating pin 59 provided upright on the lever 58 with the operating member 42 on the car door 25 side. As shown in fig. 6 to 8, a torsion spring 65 is provided on the rotation shaft, and a rotational force in the opposite direction to the rotational direction of the rotation is applied by the engagement between the rotation shaft and the operating member 42.
With this configuration, the operating pin 59 can be always returned to the correct position in a state where the operating pin 59 is not engaged with the operating member 42.
In the above configuration, when the car doors 25 are in the closed state, the operating member 42 on the car door 25 side shown in fig. 3 does not abut against and engage with the operating pin 59 on the link mechanism 41 side, and the link mechanism 41 does not receive an urging force from the car door 25 side. Therefore, the blocking member 35 and the bracket 51 supporting the blocking member 35 are pulled back toward the supporting member 44 by the tension of the return spring 56 shown in fig. 4, and the blocking member 35 is positioned at the retracted position below the car side sills 31 as shown in fig. 7 and 8.
When the car 4 stops at the lobby and the car door 25 is opened and moved to a predetermined open position, the operating member 42 provided on the door panel 25a side abuts against and engages with the operating pin 59 constituting the link mechanism 41, and the lever 58 provided with the operating pin 59 is rotated counterclockwise in the figure about the pivot shaft 45 by the opening operating force of the door panel 25 a.
By this operation, the link mechanism 41 is rotated in the same direction against the tension of the return spring 56, and the holder 51 and the closing member 35 supported by the holder 51 are extended from the state of fig. 4 to the state of fig. 5. Therefore, the blocking member 35 slides leftward in the figure from the retracted position of the lower portion of the car side sills 31 shown in fig. 7 and 8, and reaches the blocking position shown in fig. 6.
In this blocking position, the blocking member 35 blocks the gap between the rocker 31, 32, and therefore small articles can be easily collected without falling into the pit from the gap. Further, since the upper surface of the blocking member 35 is positioned below the upper surfaces of the sills 31 and 32, the load of the object positioned on the sills 31 and 32 is not applied to the blocking member 35, and damage to the support portion of the blocking member 35 due to the applied load can be prevented.
In a closed state in which the gap is closed by the closing member 35, if the load of the car 4 changes greatly, the car 4 may rise slightly. Even if such temporary lifting of the car 4 occurs, the upper corner of the blocking member 35 is chamfered 35b, and the blocking member 35 is supported by the leaf spring 52, so that there is no problem such as damage.
For example, when all passengers riding in the car 4 in a full state get off the elevator at a time, the car is slightly raised temporarily. At this time, the blocking member 35 located at the blocking position shown in fig. 6 also rises and may come into contact with the side edge portion of the rocker 32 on the lobby side. However, since the upper corner portion of the blocking member 35 facing the side edge portion of the rocker 32 on the lobby side is chamfered 35b, the contact force of this portion is weakened, and damage due to contact can be prevented. Further, since the blocking member 35 is supported by the leaf spring 52, the leaf spring 52 is also deflected in the vertical direction at the time of the above-described abutment, and therefore, the impact due to the abutment is weakened by the cushioning effect thereof, and damage due to the abutment can also be prevented.
On the other hand, when the car door 25 performs a closing operation and moves to a predetermined closed door position, the operating member 42 provided on the door panel 25a side is separated from the operating pin 59 constituting the link mechanism 41. Therefore, the force applied to the link mechanism 41 via the operating pin 59 is released, and the pivot shaft 45 is rotated clockwise in the figure with respect to the link mechanism 41 by the tension of the return spring 56, and the holder 51 and the blocking member 35 supported by the holder 51 are pulled back from the state of fig. 5 to the state of fig. 4. Therefore, the blocking member 35 slides from the blocking position shown in fig. 6 to the retracted position below the car side sills 31 shown in fig. 7 and 8 to the right in the drawing.
In this way, the blocking member 35 is slidably moved from the retracted position to the blocking position by the link mechanism that is operated by receiving a moving force in the opening direction of the car door, and is slidably moved from the blocking position to the retracted position by the elastic force of the return spring during the closing operation of the car door. This sliding movement enables the stopper 61 to accurately stop the closing member 35 at both the closing position and the retracted position. Therefore, the blocking member can be reliably prevented from overtravel without stopping at a proper position, and from colliding with another member and being damaged. Further, even if the overtravel occurs, since the blocking member 35 is supported by the leaf spring 52, the impact due to the collision with another member can be buffered by the deflection of the leaf spring 52, and damage to the member can be prevented.
Further, when the leaf spring 52 is deflected, a gap is formed in the joint portion with the holder 51, and it is considered that the original shape cannot be restored if dust or the like is caught in the gap. Therefore, it is also possible to perform caulking or to provide a shield such as a cover in a portion where the gap may occur.
The leaf spring 52 has a vertical flexing function as described above. Therefore, in order to more effectively generate the vertical deflection, at least 1 bending portion toward the lateral direction may be formed at the longitudinal middle portion of the plate spring 52 so that the longitudinal elastic force is generated. The bent portion may be formed by bending the plate spring 52 into a V-shaped cross section as shown in fig. 10, or may be formed by bending the plate spring into a semicircular shape as shown in fig. 11. Further, a plurality of V-shaped bends may be formed continuously in the vertical direction, or a plurality of semicircular bends may be formed continuously in the vertical direction to form an S-shaped bend.
With this configuration, leaf spring 52 can be effectively deflected also in the longitudinal direction parallel to the plate surface.
In the above embodiment, the link mechanism 41 is configured to always pull back the holder 51 toward the support member 44 by the tension of the return spring (tension spring) 56 as shown in fig. 4 and 5, but instead of the return spring 56, an operation spring 66 that generates a repulsive force may be provided between the support member 44 and the right end of the link 47 to always apply a force that extends in the direction of fig. 5 to the holder 51. That is, the holder 51 and the closing member 35 supported by the holder 51 via the leaf spring 52 are coupled to the operating spring 66 via the link mechanism 41, and are constantly subjected to a moving force toward the closing position shown in fig. 5 and 6.
In this case, when the link mechanism 41 is in the door-closed end position shown in fig. 12 in which the car door 25 is fully closed, as shown in fig. 13, the operating pin 59 engages with the operating member 72 provided on the door panel 25a side. Therefore, the link mechanism 41 is held in the state of fig. 4 in which the repulsive force of the operation spring 66 is accumulated. That is, the blocking member 35 is held at the retracted position shown in fig. 7 and 8.
On the other hand, when the car door 25 is opened and the door panel 25a starts the door opening operation from the door closing end in fig. 12, the operating member 72 on the car door 25 side moves rightward in the drawing from the state in fig. 13, and therefore the engagement force with the operating member 72 is released. Therefore, the links 46, 47, 48, and 49 constituting the link mechanism 41 are rotated counterclockwise in the figure about the pivot shaft 45 by the repulsive force of the operating spring 66. By the operation of the link mechanism 41, the holder 51 and the closing member 35 supported by the holder 51 via the leaf spring 52 are extended from the state of fig. 4 to the state of fig. 5. That is, the closing member 35 slides from the retracted position shown in fig. 7 and 8 to the closing position shown in fig. 6.
On the other hand, when the car doors 25 are closed from the fully opened state, the door panels 25a are closed to the vicinity of the door closing ends, and the operating members 72 engage with the operating pins 59 on the link mechanism 41 side as shown in fig. 13. Therefore, the lever 46 having the actuating pin 59 is driven clockwise in the drawing by the force in the closing direction of the door panel 25 a. That is, the link mechanism 41 returns the bracket 51 and the blocking member 35 supported by the bracket 51 via the leaf spring 52 from the state of fig. 5 to the state of fig. 4 by the force in the closing direction of the door panel 25 a. That is, the closing member 35 slides from the closing position shown in fig. 6 to the retracted position shown in fig. 7 and 8.
In this way, the link mechanism 41 is released from engagement with the operating member 72 by starting the door opening operation of the car doors 25 from the door closing end, and therefore, the sliding movement of the blocking member 35 to the blocking position by the repulsive force of the operating spring 66 is permitted. Then, the blocking member 35 at the blocking position slides to the retracted position upon receiving the moving force of the car door 25 by engaging with the operating member 72 on the car door 25 side in accordance with the movement of the car door 25 toward the closing end.
That is, when the car door 25 starts to open, the blocking member 35 immediately moves to the blocking position. When the car door 25 is closed, the blocking member 35 moves from the blocking position to the retracted position immediately before the fully closed state. Therefore, even if a passenger or a load gets on or off the elevator during the opening or closing operation of the car door 25, the blocking member 35 blocks the gap between the sills 31 and 32, and therefore, it is possible to reliably prevent a small article from falling through the gap.
The engagement portions of the link mechanism 41 with the operating members 42 and 72 on the car door 25 side, that is, the positions where the operating pins 59 are provided are outside the front width of the doorway 24 of the car 4 opened and closed by the car door 25.
Although the embodiments of the present invention have been described, these embodiments are merely presented as examples, and are not intended to limit the scope of the invention. The above-described new embodiment can be implemented in various other embodiments, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
