Description

  An embodiment of the present invention relates to an elevator apparatus having a structure for closing a gap formed between a landing side and a sill on a car side provided at an entrance to a car.

  In an elevator system in which a car installed in the hoistway of a building moves up and down between floors to carry people and luggage, there is a constant distance between the landings on each floor and the car in order to raise and lower the car. The gap is provided. For this reason, when the car stops landing at the landing and the door of the entrance is opened, a gap (also referred to as running clearance) is generated between the landing side sill and the car side sill. The gap between the sills is dangerous because it causes a person to stumble or a wheel such as a wheelchair or a bogie falls. In addition, small articles such as keys and cards may fall into the pit from the sill gap, making recovery difficult.

  In view of this, there has conventionally been proposed a member that is provided with a closing member for closing the gap between the sills and is operated so as to close the sill gap when the door is opened (see, for example, Patent Document 1).

JP 2009-286504 A

  In such a mechanism that closes the running clearance when the door is open, as a timing for projecting and closing the closing member, as soon as the door starts to open from the door closed end, the closing member is projected to close the gap and the door is open. It was thought that it was always plugged. This timing is desirable as a function for preventing small objects from falling. However, if the act of pushing the door on purpose is carried out while the car is running, the closing member will be protruded even while the car is running, so the protruding closing member will come into contact with the goods on the landing side and break was there.

  According to the present invention, when the gap between the sill on the landing side and the sill on the car side is closed by the closing member in conjunction with the opening and closing operation of the door, the predetermined opening position set in advance is projected to reach the closing position. Thus, an object of the present invention is to provide an elevator apparatus that can prevent damage to the closing member due to contact with the landing side even when the door is opened while the car is running.

  The elevator apparatus according to an embodiment of the present invention includes a car-side sill that guides a car door provided at an entrance of a car along its opening and closing direction, and each floor on which the car can land, A plane that can block a gap formed between a sill on the landing side that guides a landing door provided at the entrance to the cradle along the opening and closing direction and a sill on the car side and the sill on the landing side. A closing member having a shape and configured to be movable between a closing position where the gap is closed and a retreat position at a lower part of the sill on the side of the car, and the opening and closing of the car door connected to the closing member In operation, when the car door reaches a predetermined open position from the door closing end, the closing member is moved to the closing position, and when the car door is closed to the predetermined position by moving to the door closing end, the closing member Is moved to the retracted position. Characterized in that a turning mechanism.

  According to the above-described configuration, when the gap between the sill on the landing side and the sill on the car side is closed with the closing member in conjunction with the opening and closing operation of the door, it protrudes to the closing position because the predetermined opening position is reached in advance. Therefore, even when the door is opened while the car is running, it is possible to earn time until the car suddenly stops, and it is possible to prevent the protruding closing member from coming into contact with the landing side and being damaged.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  First, the overall configuration of the elevator apparatus will be described with reference to FIG. As shown in FIG. 1, the elevator apparatus 1 includes a passenger car 4 and a counterweight 5 disposed in a hoistway 3. Above the hoistway 3 is provided a machine room 6 in which a hoisting machine 7 for driving a main rope 9 and a control device 8 are installed. The control device 8 controls the entire elevator device 1 and controls the hoisting machine 7 in accordance with a landing call or a car call so that the car 4 is landed on the floor where the call was made.

  A so-called machine room-less elevator device in which the hoisting machine 7 and the control device 8 are downsized and provided in the upper part in the hoistway 3 without providing the machine room 6 may be used.

  In this elevator apparatus 1, an entrance 12 that leads to a car 4 in the hoistway 3 is provided at a landing 11 provided on each floor of the building, and a landing door 2 is provided at the entrance 12. The landing door 2 is engaged with the side of the car door 25 provided at the entrance / exit 24 of the car 4 via an interlock mechanism (not shown) when the car 4 is landed, and interlocks with the opening and closing of the car door 25. Opens and closes.

  FIG. 2 is a front view of the car door 25 provided at the entrance / exit of the car 4 in the door closed end position (a state in which the car door 25 is completely closed) viewed from the platform 11 side. The car door 25 is a so-called double-opening method in which two door panels 25a and 25b (the door surface plate is not shown) are opened to the left and right in different directions. These two door panels 25a, 25b are driven in the left-right direction in the figure by a door opening / closing mechanism 27 to open / close.

  The door opening / closing mechanism 27 is a well-known one and is not directly related to the invention of the present application, so the description of the structure is omitted. It is driven in the left-right direction along the guide rail to open and close.

  A car-side sill 31 is provided at the entrance / exit part of the car 4, and the two door panels 25a and 25b constituting the car door 25 described above are slidably guided along the opening and closing direction thereof. . The car-side sill 31 is provided at the lower side of the entrance / exit 24 of the car 4 shown in FIG. 1, and the guide grooves formed on the upper surface thereof are respectively provided at the lower ends of the two door panels 25a and 25b. Engage and guide them in the opening and closing direction.

  As shown in FIGS. 7 to 9, a sill 32 is provided on the platform 11 side with respect to the sill 31 on the car side. The platform side sill 32 is disposed opposite to one side surface (the left side surface in FIGS. 6 to 8) of the car side sill 31 with a predetermined distance. A guide groove is also formed on the upper surface of the threshold 32 on the landing side, and guides the landing door 2 shown in FIG. 1 so as to be slidable along the opening and closing direction.

  The landing-side door 2 is also of a double-opening type having two door panels (not shown). As described above, when the car 4 reaches the landing 11, it engages with the car door 25 and the car door. 25 opens and closes together. That is, the landing door 2 has two door panels locked in a closed state by an interlock mechanism (not shown) when the car 4 is not landing, and when the car 4 is landing, the car 4 The locking state described above is released by engaging with an engaging member (not shown) on the side, and the door is opened and closed together with the car door 25.

  When the car 4 reaches the predetermined floor, the gap (running clearance) shown in FIGS. 7 to 9 is generated between the car-side sill 31 and the landing-side sill 32 as described above. In the embodiment of the present invention, a closing member 35 is provided to close this gap.

  As shown in FIG. 2, the closing member 35 is divided into left and right. This divided part is a part where the car-side sill 31 passes over an interlock mechanism (specifically, a roller part engaged with the car side) provided on the landing side when the car 4 is raised and lowered, In order to allow passage of the interlock mechanism, it is divided with a space left and right. That is, even if the car goes up and down with the closing member extended to the closing position, the landing-side interlock mechanism passes through the space formed in the divided portion of the extended closing member 35. The extended closing member and the interlock mechanism do not collide.

  The landing-side sill 32 is provided with a block that is loosely fitted in a protruding state in the divided space portion in a state of facing the sill 31 on the car side. This block is provided integrally with the sill 32 on the landing side facing the car-side sill 31 and facing the divided space portion of the closing member 35. Therefore, when the car 4 is landed and the landing side sill 32 and the car side sill 31 face each other, the blocks provided on the landing side sill 32 are loosely fitted in a protruding state in the divided space portion. To do. For this reason, the space generated in the divided portion is substantially blocked by the block that is loosely fitted in the divided portion, and it is possible to prevent small items from falling from the space of the divided portion.

  7 to 9, the upper surface of the closing member 35 is located below the upper surfaces of the car-side sill 31 and the landing-side sill 32. Moreover, the planar shape is formed in the shape dimension which can block | close the clearance gap between the thresholds 31 and 32 as shown in FIG. That is, it has a planar shape having a length that is slightly larger than the entrance of the car-side doorway 24 and a width that is slightly larger than the gap between the sills 31 and 32 shown in FIGS.

  Moreover, the cross section is made into a vertically long shape, and the recessed part 35a is formed in the opposing part with the illustration right side surface of the threshold 32 on the landing side. The recess 35a is provided to avoid the head of a screw 36a provided on the right side of the sill 32 on the landing side. The screw 36a is for attaching the plate 36 that partitions the space between the lower floors. Further, a chamfer 35 b is applied to the upper corner portion of the closing member 35.

  The closing member 35 may be made of metal or resin, but a resin material may be used in consideration of workability and buffering properties with other components.

  The closing member 35 is slidable between a closing position where the gap between the sills 31 and 32 shown in FIG. 7 is closed and a retreating position where the sill 31 is retracted to the lower part of the car-side sill 31 shown in FIGS. (FIG. 9 is a view in which some parts are removed from FIG. 8 in order to make it easier to see the state of the closing member 35 in the retracted position). The drive mechanism 41, which will be described later, slides between the closing position and the retracted position as the car door 25 is opened and closed.

  The closing member 35 is attached to a bracket 51 provided on the drive mechanism 41 side via a leaf spring-like elastic member (hereinafter referred to as a leaf spring) 52. Therefore, the closing member 35 is supported by the leaf spring 52 so as to be swingable in the interval direction between the car-side sill 31 and the landing-side sill 32 (which is also the front-rear direction with respect to the sliding movement direction). The bracket 51 and the leaf spring 52 are also divided at the same portion as the closing member 35, and support the divided corresponding portions of the closing member 35.

  As shown in FIGS. 3 and 4, the drive mechanism 41 is configured to be able to engage with the operation member 42 on the car door 25 side as the car door 25 opens and closes. Then, the force received from the operating member 42 by the engagement with the operating member 42 is converted into the sliding movement direction of the closing member 35, and the closing member 35 is driven in the sliding movement direction. That is, the drive mechanism 41 is connected to the closing member 35, and the closing member 35 is moved to the closing position shown in FIG. 7 when the car door 25 reaches the predetermined open position from the door closing end in accordance with the opening / closing operation of the car door 25. When the car door 25 is slid and closed to a predetermined position by moving the car door 25 to the door closing end, the closing member is slid to the retracted position shown in FIGS.

  In this embodiment, as shown in FIGS. 5 and 6, the drive mechanism 41 can be rotated via four links 46, 47, 48, 49 and one end of each of these links and a connecting shaft 50. And a bracket 51 connected thereto. The four links 46, 47, 48, and 49 are rotatably supported via a pivot shaft 45 on a support member 44 provided on the car 4 side.

  Out of these four links, the inner links 47 and 48 are for connection driving, and the other end thereof is connected to a connection rod 55 via a connection shaft 54. The inner links 47 and 48 and the connecting rod 55 are used to interlock the left and right parts of the closing member 35 and the accompanying bracket 51 and leaf spring 52, and these divided parts operate integrally. . A repulsion spring 56 is installed between the right end of the connecting rod 55 in the figure and the support member 44, and constantly applies a force in the direction of drawing the bracket 51 downward from the support member 44 side to the drive mechanism 41. .

  A base end portion of a lever 58 is integrally attached to the pivot shaft 45 of the link 46 constituting the drive mechanism 41. An operating pin 59 is erected at the tip of the lever 58. As shown in FIGS. 3 and 4, the upper side surface of the operation pin 59 is disposed so as to be engageable with an operation member 42 provided integrally with the door panel 25 a of the car door 25.

  As shown in FIG. 4, the operating member 42 includes a flat portion 42 a and an inclined portion 42 b that engage with the operating pin 59. In the flat portion 42a, when the door 25 is in the door closed end position shown in FIG. 2, the operating pin 59 is pushed up as shown by the broken line in FIG. 4, and the lever 58 and the pivot shaft 45 integrated therewith are shown in the drawing. It is in a state of rotating around. As a result of this rotation, the link 46 integral with the pivot shaft 45 and the other links 47, 48, 49 connected via the bracket 51 also counterclockwise against the repulsive force of the repulsion spring 56. It is in a rotated state. That is, the drive mechanism 41 is maintained in the state shown in FIG. 5 when the operating pin 59 is engaged with the flat portion 42 a of the operating member 42, and is supported by the bracket 51 and the upper portion thereof via the leaf spring 52. The member 35 is held at the retracted position shown in FIGS.

  The state of FIG. 5 is maintained for the length X of the flat portion 42a shown in FIG. That is, even if the door panel 25a moves to the right in the figure by the opening operation of the door 25, the state of FIG. 5 is maintained while the operating pin 59 is engaged with the flat portion 42a.

  When the car door 25 moves from the door closed end to a predetermined open position, the operation pin 59 comes off the flat portion 42a and engages with the inclined portion 42b as shown in the actual battle of FIG. The lever 58 having the actuating pin 59 is repelled by the repulsion spring 56 shown in FIGS. 5 and 6 via links 46, 47, 48, 49 connected via the bracket 51 and the pivot shaft 45. The counterclockwise turning force shown in the figure is applied. For this reason, when the operating pin 59 engages with the inclined portion 42b, they rotate counterclockwise as shown in the figure, and the bracket 51 and the closing member 35 supported on the upper portion thereof via the leaf spring 52 are shown in FIG. 6 is pulled out from the state to the state shown in FIG. 6 and slid to the closing position shown in FIG.

  Here, the repulsion spring 56 described above is finally connected to the closing member 35 via the drive mechanism 41 and the bracket 51, and the closing member 35 is connected to the closing member 35 via the drive mechanism 41 in FIGS. It is actuated to the closing position shown. Therefore, the repulsion spring 56 functions as an operating spring that operates the closing member 35 to the closing position (hereinafter referred to as an operating spring 56).

  As described above, the drive mechanism 41 is moved from the door closed end to the predetermined open position so that the engagement force with the operation member 42 on the car door side is released, and the drive spring 56 moves to the closing position by the operation spring 56. Allow slide movement. Further, when the car door 25 is closed, as will be described later, the car door 25 is engaged with the actuating member 42 on the car door side during the movement to the door closing end, and the car door 25 receives the moving force of the car door 25 to close the car door 25. The member 35 is configured to slide to the retracted position.

  For the above-described sliding movement of the closing member 35, a stopper 61 for stopping the closing member 35 at the closing position and the retracted position is provided on the support member 44 as shown in FIGS. FIG. 10 shows the stopper 61 taken out. The stopper 61 has a U-shaped member fixedly installed on the support member 44, and is provided with a cushioning material 62 such as rubber on both inner side surfaces thereof, and is extended from the bracket 51 on the closing member 35 side therebetween. A contact member 63 having an L-shaped cross section is disposed.

  With this configuration, the abutting member 63 extended from the bracket 51 abuts on both inner side surfaces of the U-shaped member of the stopper 61, so that the sliding movement of the closing member 35 is correctly stopped at the closing position and the retracted position. be able to. The cushioning material 62 such as rubber may be provided on one or both of the stopper 61 and the contact member 63.

  Of the pivot shaft 45 that constitutes the drive mechanism 41, the one disposed at the right end in FIGS. 2 and 3 is integral with the lever 58, and the operating pin 59 erected on the lever 58 is provided on the side of the car door 25. This is a rotating shaft that rotates by engaging with the operating member 42. As shown in FIGS. 7 to 9, a torsion spring 65 is provided on the rotating shaft, and a rotational force that resists the rotating direction due to the engagement with the operating member 42 is applied.

  With this configuration, the operating pin can always be returned to the correct position when the operating pin 59 is not engaged with the operating member 42.

  In the above configuration, when the car door 25 is in the door closed end position, the actuating member 42 on the car door 25 side shown in FIG. 3 has a driving mechanism 41 at its flat portion 42a as shown by the broken line in FIG. The driving mechanism 41 is held in the state shown in FIG. 5 against the spring force of the operating spring 56. Therefore, the closing member 35 and the bracket 51 that supports the closing member 35 are in the retracted position below the car side sill 31, as shown in FIGS.

  When the car 4 reaches the landing, the car door 25 starts to open. The operation pin 59 is engaged with the flat portion 42a for a while after the opening operation of the car door 25 is started, and continues for the length X of the flat portion 42a. Thereafter, when the car door 25 moves to a predetermined open position, the operation pin 59 constituting the drive mechanism 41 is disengaged from the flat portion 42a of the operation member 42 and engaged with the inclined portion 42b as shown in the actual battle of FIG. To do.

  That is, in the drive mechanism 41, since the car door 25 has moved from the door closed end to a predetermined open position, the operating pin 59 has been released from the engagement force with the operating member 42 on the car door side, and the operating spring 56 With the repulsive force, the bracket 51 and the closing member 35 supported by the bracket 51 are fed out from the state of FIG. 5 to the state of FIG. Accordingly, the closing member 35 slides from the retracted position shown in FIGS. 8 and 9 to the left in the drawing and reaches the closing position shown in FIG. The front end portion (the left end portion in the drawing) of the closing member 35 is in contact with the right side surface in the drawing of the sill 32 on the landing side to close the gap between the sills 31 and 32.

  Here, when an act of intentionally pushing the door open while the car is running, if the closing member protrudes immediately in conjunction with the opening of the door, the protruding closing member It was thought that the product could be damaged by contact with the equipment on the landing side.

  However, in the embodiment of the present invention, even if the door is opened, the closing member does not immediately protrude to the closing position, and the door protrudes to the closing position when the door reaches a predetermined opening position. Therefore, even when the door is opened while the car is running, it is possible to gain time until the car suddenly stops, and it is possible to prevent the protruding closing member from coming into contact with the landing side and being damaged.

  In general, an elevator apparatus is provided with a gate switch for detecting when the door is intentionally opened while the car is running, and the car is suddenly stopped when the gate switch is turned off. . As described above, in the embodiment of the present invention, even when the door is opened, the closing member does not immediately protrude to the closing position, and the door has been protruded to the closing position by reaching a predetermined opening position set in advance. During this time, the car is suddenly stopped. That is, since it protrudes to the closing position after stopping, the protruding closing member does not come into contact with the landing gear and break.

  For this purpose, the predetermined opening position of the door at which the closing member protrudes is the distance from the door closing end corresponding to the door opening time until the car suddenly stops when the door opening is detected while the car is running. What is necessary is just to set the length X of the flat part 42a shown in FIG. 4 so that it may become a corresponding open position.

  Here, the gap between the sills 31 and 32, that is, the clearance dimension is not a constant value, but differs depending on the installation error of each floor. Also, the dimensions fluctuate due to the back and forth play of the car guide device and the car vertical displacement when getting on and off.

  In this embodiment, the closing member 35 is attached to the bracket 51 via a leaf spring 52, and is configured to be swingable back and forth in the slide movement direction. That is, the closing member 35 can swing back and forth at the protruding position (closing position). Moreover, it is urged | biased by the board | plate spring 52 (illustration left), and when it pushes in a cage | basket | car direction (illustration right), it will retract, and when the pushing force is removed, it will return to the original closing position. .

  With this structure, when the running clearance is narrower than usual, it can be pushed back to the car side (right side in the figure), and when it is wide, it can protrude to the closing position, so it is possible to obtain a closed state with a higher degree of sealing. Become.

  Thus, when the closing member 35 is in the closing position, it closes the gap between the sills 31 and 32, so that small items do not fall into the pit from this gap and can be easily collected. Moreover, since the upper surface of the closing member 35 is located below the upper surfaces of the sills 31 and 32, the load of the object located on the sills 31 and 32 is not applied to the closing member 35, and the load is applied. Damage to the support portion of the closing member 35 can be prevented.

  When the load on the car 4 changes greatly in the state where the gap is closed by the closing member 35, the car 4 may temporarily rise slightly. Even if such a temporary raising of the car 4 occurs, the chamfer 35b is applied to the upper corner portion of the closing member 35 and the closing member 35 is supported by the leaf spring 52. Does not occur.

  For example, when a passenger who has been in a full state in the car 4 goes down at a time, the car 4 slightly rises temporarily. At this time, the closing member 35 located at the closing position shown in FIG. 6 is also lifted and brought into contact with the lower side portion of the sill 32 on the landing side. However, since the chamfer 35b is applied to the upper corner portion of the closing member 35 facing the lower side portion of the sill 32 on the landing side, the contact force of this portion is weakened, and damage due to contact can be prevented. In addition, since the closing member 35 is supported by the leaf spring 52, the leaf spring 52 is also bent in the vertical direction at the time of contact as described above. Can prevent damage due to contact.

  On the other hand, when the car door 25 is closed, the operating pin 59 constituting the drive mechanism 41 is engaged with the inclined portion 42b of the operating member 42 as shown by the solid line in the middle of the door reaching the door closed end position. Match. As the door panel 25a moves to the left in the figure (moving in the door closing direction), the operating pin 59 is moved upward in the figure, and the lever 58 and the pivot shaft 45 integral therewith are rotated clockwise in the figure. . As a result of this rotation, the link 46 integral with the pivot shaft 45 and the other links 47, 48, 49 connected via the bracket 51 also rotate clockwise as shown in the figure against the repulsive force of the operating spring spring 56. Rotate.

  That is, the driving mechanism 41 is returned to the state shown in FIG. 5 when the operating pin 59 is engaged with the inclined portion 42 b of the operating member 42, and the closing member supported by the bracket 51 and the upper portion thereof via the leaf spring 52. 35 moves to the retracted position shown in FIGS. This operation ends when the engaging position of the operating pin 59 shifts from the inclined portion 42b of the operating member 42 to the flat portion 42a, and thereafter this state is maintained until the car door 25 reaches the door closed end position. To do.

  Thus, when the car door 25 is closed, it engages with the car door side actuating member 42 in the middle of the movement to the door closing end, and receives the moving force of the car door 25 to close the closing member 35 in the closing position. Slide to the retracted position.

  The sliding movement of the closing member 35 can correctly stop the closing member 35 at both the closing position and the retracted position by the stopper 61. For this reason, it is possible to reliably prevent the blocking member 35 from overrunning without stopping at the normal position and colliding with other parts to be damaged. Even if an overrun occurs, the closing member 35 is supported by the leaf spring 52, so that an impact caused by a collision with another component can be buffered by the bending of the leaf spring 52, and damage to the component can be prevented. .

  In addition, when the leaf | plate spring 52 bends, a clearance gap may arise in the junction part with the bracket 51, and if dust etc. are pinched | interposed into this clearance gap, it will be considered that it cannot return to an original shape. Therefore, it is advisable to provide guards such as caulking and gabber installation in advance for the portion where this gap may occur.

  Further, the leaf spring 52 has a function of bending in the vertical direction as described above. For this reason, in order to generate the vertical deflection more effectively, at least one bent portion in the horizontal direction is formed in the vertical intermediate portion of the leaf spring 52 to generate a vertical spring force. Also good. As this bending part, as shown in FIG. 11, the leaf | plate spring 52 may be bend | folded in a cross-sectional square shape, or you may curve in a semicircle as shown in FIG. Furthermore, a plurality of square-shaped bends may be made continuous in the vertical direction, or a plurality of semicircles may be made continuous in the vertical direction to form an S-shaped curve.

  If formed in this way, the leaf spring 52 can be effectively deflected also in the longitudinal direction parallel to the plate surface.

  The engaging portion of the drive mechanism 41 with the operating member 42 on the side of the car door 25, that is, the position where the operating pin 59 is installed is outside the entrance 24 of the car 4 that is opened and closed by the car door 25. And

  In the above-described embodiment, each of the drive mechanisms 41 is configured to mechanically drive the door opening / closing force by converting the door opening / closing force into the moving force of the member 35. It is not limited to such a mechanical drive mechanism. For example, a drive mechanism that electrically detects that the door has reached a predetermined open or closed position, operates an actuator such as a motor, and moves the closing member may be used.

  In the above embodiment, the drive mechanism 41 slides the closing member 35 from the retracted position to the closing position. However, according to the present invention, when the gap between the sill on the landing side and the sill on the car side is closed with the closing member in conjunction with the opening and closing operation of the door, it is projected to the closing position by reaching the predetermined opening position set in advance. Thus, even when the door is opened while the car is running, it is possible to prevent the blocking member from being damaged due to contact with the landing side. The present invention can also be applied to a device that is moved in the direction to be closed. Therefore, the drive mechanism may be configured to move not only by sliding the closing member but also in combination with vertical movement and horizontal movement.

  An embodiment of the present invention relates to an elevator apparatus having a structure for closing a gap formed between a landing side and a sill on a car side provided at an entrance to a car.

  In an elevator system in which a car installed in the hoistway of a building moves up and down between floors to carry people and luggage, there is a constant distance between the landings on each floor and the car in order to raise and lower the car. The gap is provided. For this reason, when the car stops landing at the landing and the door of the entrance is opened, a gap is generated between the landing side sill and the car side sill. The gap between the sills is dangerous because it causes a person to stumble or a wheel such as a wheelchair or a bogie falls. In addition, small articles such as keys and cards may fall into the pit from the sill gap, making recovery difficult.

  In view of this, there has conventionally been proposed a member that is provided with a closing member for closing the gap between the sills and is operated so as to close the sill gap when the door is opened (see, for example, Patent Document 1).

JP 2009-286504 A

In such a mechanism that closes the running clearance when the door is open, as a timing for projecting and closing the closing member, as soon as the door starts to open from the door closed end, the closing member is projected to close the gap and the door is open. It was thought that it was always plugged. This timing is desirable as a function for preventing small objects from falling. However, if the purpose, such as push open the door act in the car traveling it has been done, for being protruded is closing even during traveling member, in contact with the Ri field side of the article that riding is projecting closing member, damage There was a problem to do.

The control device 8 controls the entire elevator device 1 and controls the hoisting machine 7 in accordance with a landing call or a car call so that the car 4 is landed on the floor where the call was made.

  A so-called machine room-less elevator device in which the hoisting machine 7 and the control device 8 are downsized and provided in the upper part in the hoistway 3 without providing the machine room 6 may be used.

  In this elevator apparatus 1, an entrance 12 that leads to a car 4 in the hoistway 3 is provided at a landing 11 provided on each floor of the building, and a landing door 2 is provided at the entrance 12. The landing door 2 is engaged with the side of the car door 25 provided at the entrance / exit 24 of the car 4 via an interlock mechanism (not shown) when the car 4 is landed, and interlocks with the opening and closing of the car door 25. Opens and closes.

FIG. 2 is a front view of the car door 25 provided at the entrance of the car 4 as seen from the landing 11 side. The car door 25 is a so-called double-opening method in which two door panels 25a and 25b (only the door contact portions are shown, and the other portions are not shown) are opened to the left and right in the drawing different from each other. These two doors panels 25a, 25b are connected to the door opening and closing Organization constructed on both sides of the doorway 24 of the car 4, more driven in the drawing the left-right direction in the door opening and closing Organization, and is opened and closed .

Incidentally, the door opening and closing Organization are well known and does not relate directly to the present invention is the structure description is omitted, the power of the motor (not shown), two doors panels 25a, 25b and in conjunction with each other, It is driven in the left-right direction along the guide rail to open and close.

  A car-side sill 31 is provided at the entrance / exit part of the car 4, and the two door panels 25a and 25b constituting the car door 25 described above are slidably guided along the opening and closing direction thereof. . This car-side sill 31 is provided at the lower side of the car doorway 24, and the guide grooves formed on the upper surface thereof engage with the lower ends of the two door panels 25a and 25b, respectively. Guide in the opening and closing direction.

  As shown in FIGS. 6 to 8, a sill 32 is provided on the platform 11 side with respect to the sill 31 on the car side. The platform side sill 32 is disposed opposite to one side surface (the left side surface in FIGS. 6 to 8) of the car side sill 31 with a predetermined distance. A guide groove is also formed on the upper surface of the threshold 32 on the landing side, and guides the landing door 2 shown in FIG. 1 so as to be slidable along the opening and closing direction.

The ride Batobira 2 also intended casement system with door panels but the two not shown, as described above, when the car 4 is implanted in landing 11, it engages with the car door 25, the car door 25 opens and closes. That is, the landing door 2 has two door panels locked in a closed state by an interlock mechanism (not shown) when the car 4 is not landing, and when the car 4 is landing, the car 4 The locking state described above is released by engaging with an engaging member (not shown) on the side, and the door is opened and closed together with the car door 25.

When the car 4 is landed to a predetermined floor, as described above, between the field side of the threshold 32 Ri-ride the sill 31 of the car side, a gap (running clearance) shown in FIGS. 6 to 8 occurs. In the embodiment of the present invention, a closing member 35 is provided to close this gap.

As shown in FIG. 2, the closing member 35 is divided into left and right. This divided part is a part where the car-side sill 31 passes over an interlock mechanism (specifically, a roller part engaged with the car side) provided on the landing side when the car 4 is raised and lowered, In order to allow passage of the interlock mechanism, it is divided with a space left and right. In other words, event, even if the lift is car while being fed to a position closing the closing member, the interlocking mechanism of the ride Ri field side, passes through the formed divided portion of the closing member 35 fed out space Therefore, the extended closing member does not collide with the interlock mechanism.

The ride Ri field side of the threshold 32, at the opposite state of the threshold 31 of the car side, blocks loosely fitted is provided to protrude to the divided space portions. This block, multiplication Ri field side of the sill 32, opposed to the sill 31 of the car side and is integrally provided at the portion facing the divided spatial portion of the blocking member 35. Therefore, the car 4 is landed, ride Ri when the threshold 32 and the car side of the sill 31 of the field side faces protrudes ride Ri field side of the sill 32 in a space portion provided block is divided into Will be loosely fitted. For this reason, the space generated in the divided portion is substantially blocked by the block that is loosely fitted in the divided portion, and it is possible to prevent small items from falling from the space of the divided portion.

The upper surface of the closing member 35, as shown in FIGS. 7 to 9, is positioned below the upper surface of the car side of the sill 31 and ride Ri field side of the threshold 32. Further, its shape of the gap between the threshold 31 and 32 are formed in a geometry that can be closed as shown in Figure 6. That is, a somewhat greater length than the frontage of the car side of the doorway 24 as shown in FIG. 2, ing and a slightly larger width than the gap threshold 31 and 32 shown in FIGS. 7-9.

  Moreover, the cross section is made into a vertically long shape, and the recessed part 35a is formed in the opposing part with the illustration right side surface of the threshold 32 on the landing side. The recess 35a is provided to avoid the head of a screw 36a provided on the right side of the sill 32 on the landing side. The screw 36a is for attaching the plate 36 that partitions the space between the lower floors. Further, a chamfer 35 b is applied to the upper corner portion of the closing member 35.

  The closing member 35 may be made of metal or resin, but a resin material may be used in consideration of workability and buffering properties with other components.

  The closing member 35 is slidable between a closing position where the gap between the thresholds 31 and 32 shown in FIG. 9 is configured (FIG. 9 is a view in which some parts are removed from FIG. 8 in order to make the state of the closing member 35 in the retracted position easy to see). The drive mechanism 41, which will be described later, slides between the closing position and the retracted position as the car door 25 is opened and closed.

The closing member 35 is attached to a bracket 51 provided on the drive mechanism 41 side via a leaf spring-like elastic member (hereinafter referred to as a leaf spring) 52. Therefore closing member 35, the leaf spring 52, is pivotal supported to be able to (also in the longitudinal direction with respect to the slide moving direction) spacing direction of the car side of the sill 31 and ride Ri field side of the threshold 32. The bracket 51 and the leaf spring 52 are also divided at the same portion as the closing member 35, and support the divided corresponding portions of the closing member 35.

  As shown in FIGS. 3 and 4, the drive mechanism 41 is configured to be able to engage with the operation member 42 on the car door 25 side as the car door 25 opens and closes. Then, the force received from the operating member 42 by the engagement with the operating member 42 is converted into the sliding movement direction of the closing member 35, and the closing member 35 is driven in the sliding movement direction. That is, the drive mechanism 41 is connected to the closing member 35, and the closing member 35 is moved to the closing position shown in FIG. 7 when the car door 25 reaches the predetermined open position from the door closing end in accordance with the opening / closing operation of the car door 25. When the car door 25 is slid and closed to a predetermined position by moving the car door 25 to the door closing end, the closing member is slid to the retracted position shown in FIGS.

  In this embodiment, as shown in FIGS. 5 and 6, the drive mechanism 41 can be rotated via four links 46, 47, 48, 49 and one end of each of these links and a connecting shaft 50. And a bracket 51 connected thereto. The four links 46, 47, 48, and 49 are rotatably supported via a pivot shaft 45 on a support member 44 provided on the car 4 side.

  Out of these four links, the inner links 47 and 48 are for connection driving, and the other end thereof is connected to a connection rod 55 via a connection shaft 54. The inner links 47 and 48 and the connecting rod 55 are used to interlock the left and right parts of the closing member 35 and the accompanying bracket 51 and leaf spring 52, and these divided parts operate integrally. . A repulsion spring 56 is installed between the right end of the connecting rod 55 in the figure and the support member 44, and constantly applies a force in the direction of drawing the bracket 51 downward from the support member 44 side to the drive mechanism 41. .

  A base end portion of a lever 58 is integrally attached to the pivot shaft 45 of the link 46 constituting the drive mechanism 41. An operating pin 59 is erected at the tip of the lever 58. As shown in FIGS. 3 and 4, the upper side surface of the operation pin 59 is disposed so as to be engageable with an operation member 42 provided integrally with the door panel 25 a of the car door 25.

  As shown in FIG. 4, the operating member 42 includes a flat portion 42 a and an inclined portion 42 b that engage with the operating pin 59. In the flat portion 42a, when the door 25 is in the door closed end position shown in FIG. 2, the operating pin 59 is pushed up as shown by the broken line in FIG. 4, and the lever 58 and the pivot shaft 45 integrated therewith are shown in the drawing. It is in a state of rotating around. As a result of this rotation, the link 46 integral with the pivot shaft 45 and the other links 47, 48, 49 connected via the bracket 51 also counterclockwise against the repulsive force of the repulsion spring 56. It is in a rotated state. That is, the drive mechanism 41 is maintained in the state shown in FIG. 5 when the operating pin 59 is engaged with the flat portion 42 a of the operating member 42, and is supported by the bracket 51 and the upper portion thereof via the leaf spring 52. The member 35 is held at the retracted position shown in FIGS.

  The state of FIG. 5 is maintained for the length X of the flat portion 42a shown in FIG. That is, even if the door panel 25a moves to the right in the figure by the opening operation of the door 25, the state of FIG. 5 is maintained while the operating pin 59 is engaged with the flat portion 42a.

When the car door 25 moves from the door closed end to a predetermined open position, the operation pin 59 comes off from the flat portion 42a and engages with the inclined portion 42b as shown by the solid line in FIG. The lever 58 having the actuating pin 59 is repelled by the repulsion spring 56 shown in FIGS. 5 and 6 via links 46, 47, 48, 49 connected via the bracket 51 and the pivot shaft 45. The counterclockwise turning force shown in the figure is applied. For this reason, when the operating pin 59 engages with the inclined portion 42b, they rotate counterclockwise as shown in the figure, and the bracket 51 and the closing member 35 supported on the upper portion thereof via the leaf spring 52 are shown in FIG. 6 is pulled out from the state to the state shown in FIG. 6 and slid to the closing position shown in FIG.

  Here, the repulsion spring 56 described above is finally connected to the closing member 35 via the drive mechanism 41 and the bracket 51, and the closing member 35 is connected to the closing member 35 via the drive mechanism 41 in FIGS. It is actuated to the closing position shown. Therefore, the repulsion spring 56 functions as an operating spring that operates the closing member 35 to the closing position (hereinafter referred to as an operating spring 56).

  As described above, the drive mechanism 41 is moved from the door closed end to the predetermined open position so that the engagement force with the operation member 42 on the car door side is released, and the drive spring 56 moves to the closing position by the operation spring 56. Allow slide movement. Further, when the car door 25 is closed, as will be described later, the car door 25 is engaged with the actuating member 42 on the car door side during the movement to the door closing end, and the car door 25 receives the moving force of the car door 25 to close the car door 25. The member 35 is configured to slide to the retracted position.

  For the above-described sliding movement of the closing member 35, a stopper 61 for stopping the closing member 35 at the closing position and the retracted position is provided on the support member 44 as shown in FIGS. FIG. 10 shows the stopper 61 taken out. The stopper 61 has a U-shaped member fixedly installed on the support member 44, and is provided with a cushioning material 62 such as rubber on both inner side surfaces thereof, and is extended from the bracket 51 on the closing member 35 side therebetween. A contact member 63 having an L-shaped cross section is disposed.

  With this configuration, the abutting member 63 extended from the bracket 51 abuts on both inner side surfaces of the U-shaped member of the stopper 61, so that the sliding movement of the closing member 35 is correctly stopped at the closing position and the retracted position. be able to. The cushioning material 62 such as rubber may be provided on one or both of the stopper 61 and the contact member 63.

  Of the pivot shaft 45 that constitutes the drive mechanism 41, the one disposed at the right end in FIGS. 2 and 3 is integral with the lever 58, and the operating pin 59 erected on the lever 58 is provided on the side of the car door 25. This is a rotating shaft that rotates by engaging with the operating member 42. As shown in FIGS. 7 to 9, a torsion spring 65 is provided on the rotating shaft, and a rotational force that resists the rotating direction due to the engagement with the operating member 42 is applied.

  With this configuration, the operating pin can always be returned to the correct position when the operating pin 59 is not engaged with the operating member 42.

  In the above configuration, when the car door 25 is in the door closed end position, the actuating member 42 on the car door 25 side shown in FIG. 3 has a driving mechanism 41 at its flat portion 42a as shown by the broken line in FIG. The driving mechanism 41 is held in the state shown in FIG. 5 against the spring force of the operating spring 56. Therefore, the closing member 35 and the bracket 51 that supports the closing member 35 are in the retracted position below the car side sill 31, as shown in FIGS.

  When the car 4 reaches the landing, the car door 25 starts to open. The operation pin 59 is engaged with the flat portion 42a for a while after the opening operation of the car door 25 is started, and continues for the length X of the flat portion 42a. Thereafter, when the car door 25 moves to a predetermined open position, the operation pin 59 constituting the drive mechanism 41 is disengaged from the flat portion 42a of the operation member 42 and engaged with the inclined portion 42b as shown in the actual battle of FIG. To do.

That is, in the drive mechanism 41, since the car door 25 has moved from the door closed end to a predetermined open position, the operating pin 59 has been released from the engagement force with the operating member 42 on the car door side, and the operating spring 56 With the repulsive force, the bracket 51 and the closing member 35 supported by the bracket 51 are fed out from the state of FIG. 5 to the state of FIG. Accordingly, the closing member 35 slides from the retracted position shown in FIGS. 8 and 9 to the left in the drawing and reaches the closing position shown in FIG. Then, the front end (shown left end) of the closing member 35 is in contact with the right side surface of the sill 32 of squared Ri field side, close the gap between the sill 31.

Here, when an act of intentionally pushing the door open while the car is running, if the closing member protrudes immediately in conjunction with the opening of the door, the protruding closing member in contact with the power of Ri place side of the article, it was thought to be damaged.

  However, in the embodiment of the present invention, even if the door is opened, the closing member does not immediately protrude to the closing position, and the door protrudes to the closing position when the door reaches a predetermined opening position. Therefore, even when the door is opened while the car is running, it is possible to gain time until the car suddenly stops, and it is possible to prevent the protruding closing member from coming into contact with the landing side and being damaged.

  In general, an elevator apparatus is provided with a gate switch for detecting when the door is intentionally opened while the car is running, and the car is suddenly stopped when the gate switch is turned off. . As described above, in the embodiment of the present invention, even when the door is opened, the closing member does not immediately protrude to the closing position, and the door has been protruded to the closing position by reaching a predetermined opening position set in advance. During this time, the car is suddenly stopped. That is, since it protrudes to the closing position after stopping, the protruding closing member does not come into contact with the landing gear and break.

  For this purpose, the predetermined opening position of the door at which the closing member protrudes is the distance from the door closing end corresponding to the door opening time until the car suddenly stops when the door opening is detected while the car is running. What is necessary is just to set the length X of the flat part 42a shown in FIG. 4 so that it may become a corresponding open position.

  Here, the gap between the sills 31 and 32, that is, the clearance dimension is not a constant value, but differs depending on the installation error of each floor. Also, the dimensions fluctuate due to the back and forth play of the car guide device and the car vertical displacement when getting on and off.

In this embodiment, the closing member 35 is attached to the bracket 51 via a leaf spring 52, and is configured to be swingable back and forth in the slide movement direction. That is, the closing member 35 can swing back and forth at the protruding position (closing position). Furthermore, riding Ri place side by the leaf spring 52 have been (shown left) biasing retraction to be pushed to the car direction (right in the figure), when the pushing force is removed, a structure to return to its original closing position ing.

  With this structure, when the running clearance is narrower than usual, it can be pushed back to the car side (right side in the figure), and when it is wide, it can protrude to the closing position, so it is possible to obtain a closed state with a higher degree of sealing. Become.

  Thus, when the closing member 35 is in the closing position, it closes the gap between the sills 31 and 32, so that small items do not fall into the pit from this gap and can be easily collected. Moreover, since the upper surface of the closing member 35 is located below the upper surfaces of the sills 31 and 32, the load of the object located on the sills 31 and 32 is not applied to the closing member 35, and the load is applied. Damage to the support portion of the closing member 35 can be prevented.

  When the load on the car 4 changes greatly in the state where the gap is closed by the closing member 35, the car 4 may temporarily rise slightly. Even if such a temporary raising of the car 4 occurs, the chamfer 35b is applied to the upper corner portion of the closing member 35 and the closing member 35 is supported by the leaf spring 52. Does not occur.

  For example, when a passenger who has been in a full state in the car 4 goes down at a time, the car 4 slightly rises temporarily. At this time, the closing member 35 located at the closing position shown in FIG. 6 is also lifted and brought into contact with the lower side portion of the sill 32 on the landing side. However, since the chamfer 35b is applied to the upper corner portion of the closing member 35 facing the lower side portion of the sill 32 on the landing side, the contact force of this portion is weakened, and damage due to contact can be prevented. In addition, since the closing member 35 is supported by the leaf spring 52, the leaf spring 52 is also bent in the vertical direction at the time of contact as described above. Can prevent damage due to contact.

  On the other hand, when the car door 25 is closed, the operating pin 59 constituting the drive mechanism 41 is engaged with the inclined portion 42b of the operating member 42 as shown by the solid line in the middle of the door reaching the door closed end position. Match. As the door panel 25a moves to the left in the figure (moving in the door closing direction), the operating pin 59 is moved upward in the figure, and the lever 58 and the pivot shaft 45 integral therewith are rotated clockwise in the figure. . As a result of this rotation, the link 46 integral with the pivot shaft 45 and the other links 47, 48, 49 connected via the bracket 51 also rotate clockwise as shown in the figure against the repulsive force of the operating spring spring 56. Rotate.

  That is, the driving mechanism 41 is returned to the state shown in FIG. 5 when the operating pin 59 is engaged with the inclined portion 42 b of the operating member 42, and the closing member supported by the bracket 51 and the upper portion thereof via the leaf spring 52. 35 moves to the retracted position shown in FIGS. This operation ends when the engaging position of the operating pin 59 shifts from the inclined portion 42b of the operating member 42 to the flat portion 42a, and thereafter this state is maintained until the car door 25 reaches the door closed end position. To do.

  Thus, when the car door 25 is closed, it engages with the car door side actuating member 42 in the middle of the movement to the door closing end, and receives the moving force of the car door 25 to close the closing member 35 in the closing position. Slide to the retracted position.

  The sliding movement of the closing member 35 can correctly stop the closing member 35 at both the closing position and the retracted position by the stopper 61. For this reason, it is possible to reliably prevent the blocking member 35 from overrunning without stopping at the normal position and colliding with other parts to be damaged. Even if an overrun occurs, the closing member 35 is supported by the leaf spring 52, so that an impact caused by a collision with another component can be buffered by the bending of the leaf spring 52, and damage to the component can be prevented. .

  In addition, when the leaf | plate spring 52 bends, a clearance gap may arise in the junction part with the bracket 51, and if dust etc. are pinched | interposed into this clearance gap, it will be considered that it cannot return to an original shape. Therefore, it is advisable to provide guards such as caulking and gabber installation in advance for the portion where this gap may occur.

  Further, the leaf spring 52 has a function of bending in the vertical direction as described above. For this reason, in order to generate the vertical deflection more effectively, at least one bent portion in the horizontal direction is formed in the vertical intermediate portion of the leaf spring 52 to generate a vertical spring force. Also good. As this bending part, as shown in FIG. 11, the leaf | plate spring 52 may be bend | folded in a cross-sectional square shape, or you may curve in a semicircle as shown in FIG. Furthermore, a plurality of square-shaped bends may be made continuous in the vertical direction, or a plurality of semicircles may be made continuous in the vertical direction to form an S-shaped curve.

  If formed in this way, the leaf spring 52 can be effectively deflected also in the longitudinal direction parallel to the plate surface.

  The engaging portion of the drive mechanism 41 with the operating member 42 on the side of the car door 25, that is, the position where the operating pin 59 is installed is outside the entrance 24 of the car 4 that is opened and closed by the car door 25. And

  In the above-described embodiment, each of the drive mechanisms 41 is configured to mechanically drive the door opening / closing force by converting the door opening / closing force into the moving force of the member 35. It is not limited to such a mechanical drive mechanism. For example, a drive mechanism that electrically detects that the door has reached a predetermined open or closed position, operates an actuator such as a motor, and moves the closing member may be used.

In the above embodiment, the drive mechanism 41 slides the closing member 35 from the retracted position to the closing position. However, the present invention provides multiply Ri when closing the member closing in conjunction with gap opening and closing operation of the door and place side sill and the car side of the sill, the closing position by reaching a predetermined open position preset The problem is that even if the door is opened while the car is running, it is possible to prevent the blocking member from being damaged due to contact with the landing side. However, the present invention can also be applied to a device that is moved in the horizontal direction to perform the closing operation.
