Description

  Embodiments of the present invention relate to an elevator running clearance closing device that closes a running clearance existing between a car sill and a landing sill with a closing plate when the car is landing on the landing.

  In an elevator, a gap called a running clearance exists between a car sill that guides a car door and a landing sill that guides a landing door. The running clearance remains between the car sill and the landing sill even when the car is landing on the landing and the car door and the landing door are opened.

  For this reason, when passengers get on and off the car, the shoes may be caught in the running clearance, or the wheel may fall into the running clearance when a wheelchair or a carriage passes over the running clearance.

  In order to improve such a problem, an elevator including a shielding plate that closes a running clearance is conventionally known. The shielding plate is supported by the car sill, and moves between the car sill and the landing sill following the opening and closing movement of the car door, and the storage position that is stored on the side of the car sill to release the running clearance. It is possible to rotate between.

Japanese Patent No. 4211730

  However, according to the conventional elevator, since the linear movement of the car door is converted into a rotational motion and transmitted to the shielding plate, it is inevitable that the configuration for operating the shielding plate becomes complicated. For this reason, for example, the operation of adjusting the posture of the shielding plate at the retracted position and the operating position or adjusting the rotation range of the shielding plate becomes complicated, and there is a problem that much labor and labor are required for the adjustment work.

  An object of the present invention is to provide an elevator running clearance closing device capable of easily adjusting the position of a weight for rotating a closing plate.

According to the embodiment, a running clearance closing device for an elevator is provided at an entrance of a car and slidably guides a lower end portion of a car door that opens and closes the entrance and slidably guides the car. A platform sill that is provided at a platform entrance and that slidably guides a lower end of a platform door that opens and closes the platform, and that can be moved up and down following the opening and closing operation of the cage door. closed drops when, with increases when the car door is open, the columnar weight which extends straight along the elevation direction, which extends along the width direction of the doorway and the door opening, in the longitudinal direction One side is provided with a closing plate supported by the car sill or the landing sill.

The closing plate has a first position straddling between the car sill and the landing sill so as to block a running clearance between the car sill and the landing sill when the car lands on the landing. , And can be rotated between a second position that stands up with respect to the car sill or the landing sill at a position deviating from the running clearance.
A weight receiving portion is provided at one end portion along the longitudinal direction of the closing plate. The weight receiving portion is pushed down by the weight that descends following the closing operation of the car door, and rotates the closing plate from the first position to the second position. When the weight rises following the opening operation, the push-down operation by the weight is released and the closing plate is allowed to rotate from the second position toward the first position. The weight receiving portion of the closing plate is erected vertically along the descending direction of the weight so that the weight is slidably contacted when pushed down by the weight.

  According to such a configuration, in a state where the closing plate is rotated from the first position to the second position as the weight is lowered, the weight slides along the weight receiving portion that stands vertically. As a result, the weight receiving portion is not pushed down any further. For this reason, for example, when the car door starts to close and the opening width of the doorway reaches a predetermined value, the weight may be adjusted so that the weight pushes down the weight receiving portion. There is no need to strictly control the relative position. Therefore, the position adjustment of the weight that rotates the closing plate can be easily performed.

  Hereinafter, embodiments will be described with reference to FIGS. 1 to 7.

  FIG. 1 schematically shows a traction type elevator 1. As shown in FIG. 1, the elevator 1 has a machine room 3 at the upper end of a hoistway 2. A car 4 and a counterweight 5 are supported on the hoistway 2 through a guide rail (not shown) so as to be movable up and down.

  A hoisting machine 6 and a control device 7 are installed in the machine room 3. The hoisting machine 6 suspends the car 4 and the counterweight 5 from the hoistway 2 via the main rope 8. The control device 7 moves the car 4 and the counterweight 5 up and down along the hoistway 2 by controlling the operation of the hoisting machine 6 in a direction to wind up or unwind the main rope 8.

  The car 4 includes an entrance 10 through which passengers enter and exit, a car door 11 that opens and closes the entrance 10, and a car sill 12 positioned at the lower end of the entrance 10. As shown in FIGS. 2 and 5, the car door 11 adopts a so-called single-opening method in which two door panels 13 a and 13 b slide in the same direction. Hangers 14a and 14b are provided on the upper portions of the door panels 13a and 13b, respectively, and the hangers 14a and 14b are suspended from hanger rails 15a and 15b attached to the upper portion of the entrance 10.

  As shown in FIGS. 3 and 5, the car sill 12 is attached to the floor of the car 4 so as to be located at the lower end of the entrance 10. The car sill 12 has a pair of sill grooves 17a and 17b into which guide shoes 16a and 16b at the lower ends of the door panels 13a and 13b are inserted. The threshold grooves 17a and 17b extend along the sliding direction of the door panels 13a and 13b, and guide the sliding of the door panels 13a and 13b in cooperation with the hanger rails 15a and 15b.

  A door driving device 18 is installed at the top of the car 4. The door drive device 18 has a wire 20 that is horizontally stretched between a pair of pulleys 19a and 19b. The wire 20 is driven by a motor (not shown), and hangers 14 a and 14 b are connected to the wire 20. Therefore, when the wire 20 is driven, the door panels 13 a and 13 b are slid in the same direction in synchronization with each other so as to open and close the doorway 10.

  As shown in FIG. 1, a landing 21 is installed for each floor A of the building. Each landing 21 includes a boarding gate 22 that leads to the hoistway 2, a boarding door 23 that opens and closes the boarding gate 22, and a boarding sill 24 positioned at the lower end of the boarding gate 22.

  The entrance / exit 22 faces the entrance 10 of the car 4 when the car 4 reaches the landing 21 of the floor A where the car 4 should stop. The landing door 23 employs a so-called single-opening method in which two door panels 25a and 25b slide in the same direction, and a hanger 26 at the upper end of each door panel 25a and 25b is attached to the upper part of the entrance 22. It is suspended from the hanger rail 27.

  As shown in FIGS. 4 and 5, the landing threshold 24 is attached to the floor of the landing 21 so as to be located at the lower end of the entrance 22. The landing sill 24 has a pair of sill grooves 29a and 29b into which guide shoes 28a and 28b at the lower ends of the door panels 25a and 25b are inserted. The sill grooves 29a and 29b extend along the sliding direction of the door panels 25a and 25b, and cooperate with the hanger rail 27 to guide the sliding of the door panels 25a and 25b.

  Further, the car door 11 of the car 4 is detachably engaged with the hall door 23 via a connecting tool (not shown) when the car 4 reaches the hall 21 of the floor A to be stopped. By this engagement, the landing door 23 follows the car door 11 to open and close the entrance 22.

  As shown in FIGS. 3 to 6, when the car 4 is landed on the landing 21, a running clearance of, for example, about 10 mm to 30 mm is provided between the car threshold 12 of the car 4 and the landing threshold 24 of the landing 21. C exists. The running clearance C extends over the entire length of the car sill 12 and the landing sill 24 and communicates with the hoistway 2.

  According to the present embodiment, the closing plate 31 that closes the running clearance C is supported by the car sill 12 of the car 4. Specifically, the closing plate 31 is an elongate strip-like element having a length dimension over the entire length of the car sill 12 and the landing sill 24 and a width dimension exceeding the running clearance C, and is a lightweight material such as an aluminum alloy. It is made of a simple metal material. The closing plate 31 has one side 31 a and another side 31 b along the length direction, and the distance between the one side 31 a and the other side 31 b defines the width dimension of the closing plate 31.

  A pair of brackets 32 (only one is shown in FIGS. 4 to 6) are fixed to both ends of the car sill 12 along the longitudinal direction. The bracket 32 is located closer to the running clearance C than the threshold grooves 17a and 17b. An upper end portion 32 a of the bracket 32 protrudes above the upper surface of the car sill 12, and one side 31 a of the closing plate 31 is interposed between the upper end portions 32 a of the bracket 32. For this reason, one side 31 a of the closing plate 31 is located on the upper surface of the car sill 12.

  Further, both end portions of one side 31 a of the closing plate 31 are supported by the upper end portion 32 a of the bracket 32 via the pivot shaft 33, respectively. The closing plate 31 is rotatable between a first position and a second position with the pivot shaft 33 as a fulcrum.

  4 and 6 show a state in which the closing plate 31 is rotated to the first position. In the first position, the closing plate 31 falls horizontally so as to straddle between the car sill 12 and the landing sill 24, and the other side 31 b of the closing plate 31 is in contact with the upper surface of the landing sill 24. Therefore, when the closing plate 31 is rotated to the first position, the closing plate 31 is advanced onto the running clearance C and closes the running clearance C from above.

  3 and 5 show a state where the closing plate 31 is rotated to the second position. In the second position, the closing plate 31 stands vertically on the upper surface of the car sill 12, and the other side 31b of the closing plate 31 is directed upward. For this reason, when the closing plate 31 is rotated to the second position, the closing plate 31 is separated from the running clearance C so as not to prevent the elevator 4 from moving up and down.

  According to the present embodiment, the load applying member 35 is fixed to the lower surface of the closing plate 31 facing the running clearance C when the closing plate 31 is rotated to the first position. The load application member 35 is an elongated strip-like element extending over the entire length of the closing plate 31, and is formed of, for example, an iron plate heavier than the closing plate 31. The load adding member 35 is fixed to the closing plate 31 at a position that is eccentric in the thickness direction of the closing plate 31 with respect to the pivot shaft 33 that is the rotation center of the closing plate 31.

  As a result, in the state in which the closing plate 31 is rotated to the second position, the closing plate 31 receives an urging force that always tries to rotate toward the first position due to the weight of the load applying member 35. Yes. Furthermore, the load application member 35 is also superposed on the back surface of the closing plate 31, thereby serving as a reinforcing member that reinforces the closing plate 31.

  According to the present embodiment, the edge 35 a along the longitudinal direction of the load application member 35 is located on one side 31 a of the closing plate 31. The load adding member 35 protrudes from the lower surface of the closing plate 31 by the thickness. For this reason, a recess 36 into which the edge 35 a of the load applying member 35 enters is formed on the upper surface of the car sill 12 corresponding to one side 31 a of the closing plate 31.

  As shown in FIGS. 3 to 6, the weight receiving portion 38 is provided at one end portion along the longitudinal direction of the closing plate 31. The weight receiving portion 38 includes an extending portion 39 and a contact portion 40. The extending portion 39 extends obliquely from one side 31 a of the closing plate 31 in a direction intersecting with the closing plate 31. The abutting portion 40 extends from the tip of the extending portion 39 toward the opposite side of the closing plate 31 and extends in a direction parallel to the closing plate 31.

  Therefore, the contact portion 40 of the weight receiving portion 38 is in a lateral state parallel to the upper surface of the car sill 12 when the closing plate 31 is rotated to the first position. Further, the abutting portion 40 of the weight receiving portion 38 stands vertically so as to be orthogonal to the upper surface of the car sill 12 when the closing plate 31 is rotated to the second position.

  In the present embodiment, the surface of the contact portion 40 of the weight receiving portion 38 is covered with a surface layer 41 made of a synthetic resin that is smoother than the weight receiving portion 38.

  The weight receiving portion 38 may be an integral structure with the closing plate 31, or may be constituted by an element different from the closing plate 31. When the weight receiving portion 38 is a separate element, the weight receiving portion 38 is preferably formed of an iron plate having a strength higher than that of the closing plate 31, and the closing plate 31 may be formed by a known means such as bolting or welding. What is necessary is just to connect.

  As shown in FIG. 2, the car 4 is equipped with an operation mechanism 44 that rotates the closing plate 31 between the first position and the second position. The operation mechanism 44 includes, as main elements, a cylindrical weight 45 and a wire rope 46 that suspends the weight 45.

  The weight 45 is supported by the side of the entrance / exit 10 of the car 4 via the guide cylinder 47. The guide cylinder 47 is attached to the car 4 in a vertically upright posture, and a weight 45 is accommodated inside the guide cylinder 47 so as to be movable up and down. The weight 45 accommodated in the guide cylinder 47 is positioned directly above the weight receiving portion 38 of the closing plate 31.

  The wire rope 46 suspends the weight 45 from the top of the car 4. Specifically, one end of the wire rope 46 is connected to the upper end of the weight 45. The other end of the wire rope 46 is guided above the guide tube 47 and connected to a rope bracket 49 fixed to the hanger 14 a via a pulley 48.

  As shown in FIG. 2, the pulley 48 is located right above the guide tube 47 and is located at the right end of the hanger rail 15a. Therefore, the pulley 48 guides the wire rope 46 in the direction of the hanger 14 a that slides along the hanger rail 15 a by changing the travel route of the wire rope 46 guided above the weight 45 by 90 °.

  According to the present embodiment, when the car door 11 closes the entrance 10 of the car 4, the hanger 14a having the rope bracket 49 is located near the right end of the hanger rail 15a as shown in FIG. .

  For this reason, the wire rope 46 connected to the rope bracket 49 is drawn downward via the pulley 48, and the weight 45 is positioned at the bottom dead center protruding below the guide cylinder 47. In the state where the weight 45 is located at the bottom dead center, the lower end of the weight 45 abuts against the contact portion 40 of the weight receiving portion 38 as shown in FIGS. Therefore, the length of the wire rope 46 from which the weight 45 is suspended is adjusted so that the weight 45 is positioned at the bottom dead center when the car door 11 closes the doorway 10.

  When the lower end of the weight 45 abuts against the abutting portion 40 of the weight receiving portion 38, the weight receiving portion 38 is pushed down by the weight of the weight 45, and the weight receiving portion 38 is connected to the closing plate 31 as indicated by an arrow X in FIG. Together, it pivots clockwise about the pivot shaft 33. Since the weight 45 maintains a state in which the weight 45 is in contact with the contact portion 40 due to its own weight, the closing plate 31 is held at a second position that stands vertically on the upper surface of the car sill 12.

  On the other hand, when the car 4 reaches the landing 21 of the floor A to be stopped and the car door 11 is slid in the direction to open the doorway 10, the hanger 14a having the rope bracket 49 is placed on the left end of the hanger rail 15a. Slide towards. Thereby, the wire rope 46 pulls up the weight 45 from the bottom dead center. The weight 45 rises while being guided by the guide cylinder 47, and the lower end of the weight 45 is detached from the contact portion 40 of the weight receiving portion 38.

  As a result, the weight 45 is separated from the weight receiving portion 38, and the push-down operation of the weight receiving portion 38 by the weight 45 is released. Therefore, as shown by an arrow Y in FIG. 6, the closing plate 31 rotates counterclockwise around the pivot shaft 33 due to the weight of the load applying member 35, and the other side 31 b of the closing plate 31 is the landing threshold 24. Touch the top surface. Therefore, the closing plate 31 is held at the first position where it is horizontally collapsed so as to straddle between the car threshold 12 and the landing threshold 24, and the running clearance C is closed by the closing plate 31.

  Further, when the closing plate 31 is rotated to the first position, the edge 35a of the load applying member 35 enters the recess 36 on the upper surface of the car sill 12, as best shown in FIG. For this reason, when the entrance / exit 11 and the entrance / exit 22 are opened and passengers get on and off the car 4, when the closing plate 31 is stepped and the closing plate 31 bends downward, the edge portion 35 a of the load adding member 35. It hits the upper surface of the recess 36 of the basket cage 12.

  For this reason, since the edge 35a of the load applying member 35 supports and reinforces the closing plate 31 from below, it is possible to prevent excessive deformation and damage of the closing plate 31, and to the pivot shaft 33 that supports both ends of the closing plate 31. It is possible to avoid applying excessive force.

  According to such an embodiment, in the state where the closing plate 31 is rotated to the second position as the weight 45 is lowered, the contact portion 40 of the weight receiving portion 38 that contacts the weight 45 is Stands vertically along the descending direction. In other words, the lowering direction of the weight 45 and the direction of the contact portion 40 are the same.

  Therefore, after the closing plate 21 is rotated to the second position, the weight 45 slides along the standing contact portion 40 and does not push down the contact portion 40 any more. In particular, in this embodiment, the surface of the contact portion 40 is covered with the smooth surface layer 41, so that the weight 45 slides smoothly along the surface layer 41 without being caught by the contact portion 40.

  Therefore, for example, when the car door 11 starts to close and the opening width of the entrance / exit 10 becomes 125 mm or less that prevents passengers from passing, the position of the weight 45 is set so that the lower end of the weight 45 abuts against the contact portion 40 of the weight receiving portion 38. Adjust it. Therefore, it is not necessary to strictly manage the relative position between the contact portion 40 of the weight receiving portion 38 and the lower end of the weight 45, and the position adjustment of the weight 45 for rotating the closing plate 31 can be easily performed. Can do.

  At the same time, when the car door 11 is fully opened and the closing plate 31 is rotated to the first position, the abutting portion 40 of the weight receiving portion 38 is in a lateral orientation parallel to the upper surface of the car sill 12. Is held in. For this reason, when the car door 11 starts to close and the opening width of the entrance / exit 10 becomes, for example, 125 mm or less, the lower end of the weight 45 abuts against the contact portion 40 vertically.

  Therefore, it is possible to easily manage the position of the weight 45 with respect to the contact portion 40 and set the timing at which the closing plate 31 starts to move from the first position to the second position.

  Further, even when the weight 45 is slightly moved when the closing plate 31 is rotated to the second position following the closing operation of the car door 11, the weight 45 is not in contact with the contact portion 40 of the weight receiving portion 38. Stops sliding along. Therefore, the closing plate 31 rotated to the second position can be prevented from undesirably moving and the posture of the closing plate 31 can be prevented from changing, and the raising / lowering movement of the car 4 is not hindered.

  In addition, even if the wire rope 46 that suspends the weight 45 is extended, the weight 45 is slidably in contact with the contact portion 40 of the weight receiving portion 38 when the car door 11 is closed. It is kept. For this reason, the contact part 40 of the weight receiving part 38 is not further pushed down by the weight 45, and the movement of the closing plate 31 can be prevented, and the work of readjusting the position of the weight 45 with respect to the weight receiving part 38 is unnecessary. Become.

  In the present embodiment, as already described, in the state in which the closing plate 31 is rotated to the second position where the running clearance C is opened, the contact portion 40 of the weight receiving portion 38 extends along the lifting and lowering direction of the weight 45. Standing upright. For this reason, the timing at which the weight 45 is separated from the contact portion 40 can be controlled following the opening operation of the car door 11 by appropriately setting the region in which the weight 45 is in sliding contact with the contact portion 40.

  In other words, if the hanging position of the weight 45 is set so that the weight 45 continues to be in sliding contact with the contact portion 40 even when the weight 45 starts to rise, the closing plate 31 does not move even when the car door 11 starts to open. The state held at the second position is maintained. Accordingly, it is possible to easily cope with so-called running door opening in which the car door 11 is moved in the opening direction before the car 4 reaches the landing 21 of the floor A to be stopped, and the closing plate 31 is provided when the running door is opened. It is possible to prevent the noise from colliding with the landing sill 24 and damage to the closing plate 31 in advance.

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.

  For example, the closing plate is not restricted to being attached to the car sill of the car, and the closing board may be attached to the landing sill of the hall and may be rotated following the opening / closing of the landing door. However, when the closing plate is attached to the landing sill, it is necessary to provide a closing plate and an operation mechanism for each floor.
