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 is generated between the landing side sill and the car side sill. The gap between the thresholds makes it difficult to collect small articles such as keys and cards dropped by passengers in the pit.

  In view of this, there has been proposed a closing member that closes the gap between the sills and operates so as to close the sill gap when the door is opened (see, for example, Patent Document 1). That is, when the car reaches the predetermined floor and the door opens, the closing member moves to the closing position where the gap between the sills is closed. Further, when the door is closed, the closing member is configured to move from the closing position to a retracted position below the car side sill.

  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.

  2 and 3 are front views of the car door 25 provided at the entrance of the car 4, as seen from the landing 11 side. FIG. 2 shows a door open state in which the car door 25 is opened. FIG. The door closed state in which the door 25 is closed is shown. 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 door panels 25a and 25b are connected to a door opening / closing mechanism, and are driven to open / close by the door opening / closing mechanism in the horizontal direction in the figure.

  The door opening / closing mechanism is a well-known one and is not directly related to the present invention, so the description of the structure is omitted. However, the two door panels 25a and 25b are interlocked with each other by the power of a motor (not shown) to guide It is driven in the left-right direction along the rail to open and close.

  A car-side sill 31 is provided at the entrance / exit portion of the car 4, and guides the two door panels 25 a and 25 b constituting the car door 25 along its opening and closing direction. The 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 to open and close them. Guide in the direction.

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

  The landing door 2 is also of a double door type having two door panels (not shown). As described above, when the car 4 reaches the landing 11, the car door 25 is engaged with the car door 25. It 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, a gap shown in FIGS. 7 and 8 is generated between the car-side sill 31 and the landing-side sill 32. A closing member 35 is provided to close this gap. As shown in FIGS. 2 and 3, the closing member 35 is divided into right and left. This divided portion is a portion in which the car-side sill 31 passes by an interlock mechanism (not shown) provided on the landing side when the car 4 is raised and lowered, and is spaced from side to side to allow passage of the interlock mechanism. It is divided to keep.

  It should be noted that when the car 4 is landed, the interval between the divided portions is inserted by a not-shown convex portion provided in the corresponding portion of the landing side sill 32, and is substantially blocked by the convex portion.

  As shown in FIGS. 7 and 8, 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 shown in FIG. 2 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, buffering properties with other parts, and the like.

  The closing member 35 is configured to be movable 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 FIG. . 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 via a leaf spring 52 on a bracket 51 provided on the drive mechanism 41 side. As shown in FIG. 4, the drive mechanism 41 is configured to be able to engage with the operation member 72 on the car door 25 side as the car door 25 opens and closes. Then, the force received from the actuating member 72 by the engagement with the actuating member 72 is converted into the moving direction of the closing member 35, and the closing member 35 is moved in the retracting direction.

  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. An actuating spring 56 that generates a repulsive force is provided between the right end of the connecting rod 55 in the figure and the support member 44, and a force that translates the bracket 51 in the direction of pushing it from the state of FIG. 5 to the state of FIG. give.

  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 FIG. 4, the upper side surface of the operating pin 59 is disposed so as to be engageable with an operating member 72 provided integrally on the door panel 25 a side of the car door 25.

  The operation pin 59 is engaged with an operation member 72 provided on the door panel 25a side as shown in FIG. 4 when the car door 25 is in the door closed end position shown in FIG. 3 in which the car door 25 is completely closed. For this reason, the drive mechanism 41 is held in the state of FIG. 5 in which the repulsive force of the operating spring 56 is stored. That is, the closing member 35 is held at the retracted position shown in FIG.

  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 of FIG. 3, the operation member 72 on the car door 25 side is moved to the right in the state shown in FIG. Therefore, the engagement with the actuating member 72 is released. For this reason, each link 46, 47, 48, 49 constituting the drive mechanism 41 is rotated counterclockwise in the figure about the pivot shaft 45 by the repulsive force of the operating spring 56. By the operation of the drive mechanism 41, the bracket 51 and the closing member 35 supported on the bracket 51 via the leaf spring 52 are extended from the state of FIG. 5 to the state of FIG. That is, the closing member 35 moves from the retracted position shown in FIG. 8 to the closing position shown in FIG.

  On the other hand, when the car door 25 is closed from the fully opened state shown in FIG. 2, the door panel 25a is closed to the vicinity of the door closing end shown in FIG. Engage as shown. For this reason, the lever 58 having the operating pin 59 is driven in the clockwise direction in the drawing by the force in the closing direction of the door panel 25a. That is, the drive mechanism 41 returns the bracket 51 and the closing member 35 supported on the bracket 51 via the leaf spring 52 from the state of FIG. 6 to the state of FIG. 5 by the force in the closing direction of the door panel 25a. Therefore, the closing member 35 moves from the closing position shown in FIG. 7 to the retracted position shown in FIG.

  As described above, the drive mechanism 41 is disengaged from the actuating member 72 by the door opening operation from the door closing end of the car door 25, so that the closing member 35 is moved to the closing position by the repulsive force of the actuating spring 56. Allow movement. Further, as the car door 25 moves to the door closing end, it engages with the actuating member 72 on the car door 25 side, receives the moving force of the car door 25, and moves the closing member 35 at the closing position to the retracted position. .

  The closing member 35 moves to the retracted position as described above with the door closing operation. As shown in FIG. 9, a groove 81 is formed in a direction perpendicular to the paper surface (in the direction of the entrance / exit 24 shown in FIG. 2) on the lower surface of the car-side sill 31 facing the upper surface of the closing member 35 in this retracted position. Form along.

  The width of the groove 81 in the direction orthogonal to the frontage direction (the horizontal direction in the drawing) is preferably larger than the moving stroke of the closing member 35 from the closing position to the retracted position.

  In the above configuration, when the car 4 is landed and the car door 25 is opened from the fully closed state, the drive mechanism 41 is disengaged from the actuating member 72. The closing member 35 is moved from the retracted position shown in FIG. 5 to the closing position shown in FIG. 6 to close the gap between the sills 31 and 32. In this manner, the passenger 25 gets in and out of the car 4 through the doorway 24 while the door 25 is opened and the gap between the sills 31 and 32 is closed by the closing member 35. At this time, foreign matter such as sand particles adhering to the passenger's shoes may fall on the closing member 35 closing the gap.

  Thereafter, the door 25 is closed to move the car to the floor where the car was called. With this door closing operation, the drive mechanism 41 slides the closing member 35 toward the retracted position below the car-side sill 31. At this time, the foreign matter on the closing member 35 also moves in the same direction, and the foreign matter 83 enters between the lower surface of the sill 31 and the upper surface of the closing member 35 from the lower left end of the car side sill 31 in the figure. However, since the groove 81 is formed on the lower surface of the sill 31 facing the upper surface of the closing member 35, foreign matter that has entered between the lower surface of the sill 31 and the upper surface of the closing member 35 enters the groove 81. For this reason, unlike the conventional case, the foreign matter 83 is sandwiched between the upper surface of the closing member 35 and the lower surface of the car-side sill 31, and the movement of the closing member 35 is not hindered.

  Further, as shown in FIG. 9, when the width of the groove 81 in the illustrated horizontal direction is larger than the movement stroke of the closing member 35 from the closing position to the retracted position, the foreign matter 83 that has entered the groove 81 It is not sandwiched between the inner surface on the right side in the figure and the right end part of the closing member 35 in the figure, and an uncertain operation of the closing member due to the foreign object being caught can be prevented.

  The foreign matter 83 that has entered the groove 81 falls downward as the closing member 35 moves to the closing position, so that the foreign matter 83 does not accumulate in the groove 81.

  Furthermore, as shown in FIG. 10, by providing a return portion 81a formed on the inner surface of the groove 81 on the gap side (the left side in the drawing) with an acute angle upward from its lower end side. By moving the closing member 35 toward the closing position (moving leftward in the drawing), the foreign matter 83 attached to the upper surface of the closing member 35 can be more reliably removed.

  As described above, since the groove 81 is formed on the lower surface of the car-side sill 31 facing the upper surface of the closing member 35 in the retracted position, the foreign matter 83 riding on the upper surface of the closing member 35 is removed during the retracting operation of the closing member 35. Enter the space of the groove 81. For this reason, unlike the conventional case, the foreign matter 83 is sandwiched between the upper surface of the closing member 35 and the lower surface of the car-side sill 31, and the movement of the closing member 35 is not hindered.

  In the above-described embodiment, the drive mechanism 41 is configured to constantly push the bracket 51 toward the landing side by the repulsive force of the operating spring 56 as shown in FIGS. 5 and 6. Instead of 56, a return spring 66 that generates a tensile force may be provided at the same place, and the bracket 51 and the closing member 35 supported by the bracket 51 may be configured to always apply a force to pull back to the retracted position shown in FIG. .

  In this case, as shown in FIG. 11, the operation pin 59 constituting the drive mechanism 41 comes into contact with and engages with the operation member 42 provided on the door panel 25a by the opening operation of the car door 25, so Rotate clockwise. That is, the operating pin 59 abuts and engages with the operating member 42 by opening the car door 25 to a predetermined open position, and the lever 58 and the pivot shaft 45 integral therewith are rotated counterclockwise in the drawing. Let By the operation of the drive mechanism 41, the closing member 35 supported by the bracket 51 and the upper portion thereof via the leaf spring 52 is extended from the retracted position to the closing position.

  Although several embodiments of the present invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
