Description

  The present invention relates to an elevator in which a car moves up and down in a hoistway.

  Conventionally, an elevator including a closing body that closes a gap between a car and a landing at a landing position is known (see Patent Document 1). Specifically, as shown in FIGS. 15 and 16, the elevator includes a car 102 that moves up and down the hoistway 101 and a landing 103 on which the car 102 is landed (stopped). The platform 103 includes a floor-side entrance 104 and a platform-side sill 105 extending horizontally at the lower end of the entrance 104. The car 102 is a blockage that blocks the gap 108 between the entrance 106 for entering and exiting the car 102, the car-side sill 107 extending horizontally at the lower end of the entrance 106, and the landing-side sill 105 and the car-side sill 107 at the landing position. And a body 109. The closing body 109 has a plate-like portion 110 that protrudes from a position below the upper end of the car-side sill 107 in the car 102 toward the landing 103 and extends in the horizontal direction (see FIG. 16). The closing body 109 has a length corresponding to at least the width of the entrance / exit 106 of the car 102 and extends to a position close to the landing side sill 105.

  According to the elevator 100 described above, the gap between the landing side sill 105 and the car side sill 107 is closed by the closing body 109 when the car 102 is in the landing state. For this reason, even when passengers get on and off the car 102, even if their belongings are accidentally dropped between the landing side sill 105 and the car side sill 107, they are received by the closing body 109, and the belongings are received in the hoistway 101. It is prevented from falling to.

  However, in the elevator, at the landing position, the landing side sill 105 extending in the horizontal direction and the closing body 109 extending in the same direction (horizontal direction) (specifically, the leading edge in the protruding direction of the plate-like portion 110). Since there is only a slight gap between them, when the car 102 passes through the landing 103 during elevation, specifically, when the leading edge of the plate-like portion 110 passes near the landing-side sill 105, the plate-like portion 110. There are few escape routes for air pushed down or pushed up by this, and noise (so-called buffing) is generated.

  Then, this invention makes it a subject to provide the elevator which can suppress the buff sound when a car passes a landing while preventing the fall of the object from between a landing side sill and a car side sill. .

An elevator according to the present invention is a car that moves up and down in a hoistway, and includes a doorway and a car-side sill extending horizontally at the lower end of the doorway, A platform having a floor side entrance and a platform side sill extending in the horizontal direction at the lower end of the entrance.

  According to such a configuration, the fall prevention portion protrudes from one of the car and the landing at the lower end of the doorway or at a position below the lower end, so that there is a gap between the car side sill at the landing position and the landing side sill. The fall of the object from can be prevented.

  Moreover, since at least a part of the fall prevention part extends in the intersecting direction, the fall prevention part and the car side sill when the fall prevention part passes near the car side sill or the landing side sill by raising and lowering the car or The escape route of the air pushed down or pushed up by the fall prevention part between the platform side sill is increased (see FIG. 8), and thereby the buffing sound when the car passes through the platform is suppressed.

In the elevator, the fall prevention unit may include a plurality of members arranged at intervals in the horizontal direction, and each of the plurality of members may include the protruding portion .

  According to such a configuration, when the car passes through the landing at the time of ascending / descending, the air pushed down or pushed up by the fall prevention part can escape from between the adjacent members, thereby making the buffing sound more effective. Can be suppressed.

  In this case, it is preferable that the other of the car and the landing has a protruding portion that protrudes toward one of the car and the landing and is positioned between the adjacent members at the landing position.

  According to such a configuration, in the gap between the car-side sill at the landing position and the landing-side sill, the adjacent members (members constituting the fall prevention unit) are also blocked by the protrusions, so the car-side sill and the landing side It is possible to more reliably prevent the object from falling from the gap with the sill.

  As described above, according to the present invention, it is possible to provide an elevator capable of preventing an object from falling between the landing side sill and the car side sill and suppressing buffing noise when the car passes the landing. it can.

  The landing-side sill 43 is disposed at the tip of the floor (floor) at the entrance / exit 41 on the side of the hoistway 2 and has a guide groove 431 for guiding the landing-side door panel 42 on the upper surface. The guide groove 431 extends in the width direction of the doorway 41 (frontage direction: left-right direction in FIG. 4). The landing side sill 43 is fixed to the floor in a state where it protrudes into the hoistway 2 from the floor (floor) on which the landing side sill 43 is arranged (see FIG. 3).

  As shown in FIG. 5, the car 3 is guided by the first guide rail 5 to move up and down in the hoistway 2 and land on the landing 4 on a predetermined floor of the building. The car 3 includes an entrance / exit 301 and a car-side sill 33 that extends in the horizontal direction at the lower end of the entrance / exit 301. Specifically, the car 3 includes a car room (car body) 30 having an entrance / exit 301, a car-side door panel 32 that opens and closes the entrance / exit 301 of the car room 30, and a lower end of the entrance / exit 301 on the landing side of the car room 30. (Specifically, the car-side sill 33 has a plate-like member 31 such as a fisher plate or a toe guard extending downward from the car-side sill 33, and a car side that guides the lower end of the car-side door panel 32 in the opening and closing direction. It has a sill 33 and a door opening / closing device 34 that opens and closes the car-side door panel 32. Further, the car 3 protrudes toward the landing 4 from the lower end of the entrance / exit 301 or a position below the lower end, and prevents the object from falling between the car-side sill 33 and the landing-side sill 43 at the landing position. A drop prevention unit 35 is provided. The fall prevention part 35 of the present embodiment is fixed to the plate member 31. The car 3 also has an engagement device 39 for transmitting the power when the door opening and closing device 34 opens and closes the car side door panel 32 to the landing side door panel 42. The engagement device 39 engages with the engaged portion 45 disposed on the landing-side door panel 42 when the car 3 that has moved up and down in the hoistway 2 is landed on a predetermined landing 4, and opens and closes the door. The power from 34 is transmitted to the landing side door panel 42.

  The car-side sill 33 is arranged at the tip of the lower end of the entrance 301 in the car room 30 on the landing 4 side, and has a guide groove 331 for guiding the car-side door panel 32 on the upper surface.

  At least a part of the fall prevention unit 35 extends in a direction that intersects the horizontal direction (the width direction of the entrance / exit 301 of the car 3; in the example of the present embodiment, the direction in which the landing side sill 43 extends). This fall prevention part 35 has a plurality of members (first member 36, second member 37) arranged in the horizontal direction at intervals (two in the example of the present embodiment). At least one of the plurality of members (members constituting the fall prevention unit 35) 36, 37 extends in a direction intersecting the horizontal direction. In the fall prevention unit 35 of the present embodiment, each of the plurality of members (first member 36 and second member 37) extends in a direction intersecting the horizontal direction (see FIG. 5).

  The cross section at each position in the longitudinal direction of the first member 36 has the same shape. As shown in FIG. 6, the first member 36 includes a fixed portion 361 that extends in the vertical direction in the cross section and is fixed to the plate-like member 31, and a protruding portion 362 that extends from the lower end of the fixed portion 361 to the landing side in the cross section. And a return portion 363 extending in the inclined direction toward the fixed portion 361 side upward from the tip of the protruding portion 362 in the cross section.

  The protruding portion 362 extends to a position where the distance between the tip of the protruding portion 362 and the tip of the landing side sill 43 is slightly (for example, about 10 mm) when facing the landing side sill 43 by raising and lowering the car 3 (FIG. 3). And FIG. 4). The protruding portion 362 of the present embodiment has a plurality of through holes 3620 arranged at intervals in the longitudinal direction in order to suppress air resistance when the car 3 is raised and lowered.

  The first member 36 described above is disposed in an inclined state so that one end is positioned above the other end (see FIG. 5). In the width direction of the entrance / exit 301, the first member 36 has a position where one end (the right end in FIG. 5) is outside a predetermined distance from one end of the entrance / exit 301, and the other end (the left end in FIG. 5). Has a length dimension that is about 2/3 of the width of the entrance / exit 301 from one end of the entrance / exit 301.

  The cross section at each position in the longitudinal direction of the second member 37 has the same shape as the cross section of the first member 36. That is, as shown in FIG. 7, the second member 37 has a fixing part 371, a protruding part 372, and a return part 373. The protruding portion 372 has a through hole 3720 similarly to the protruding portion 362 of the first member 36.

  The length dimension of the second member 37 is smaller than the length dimension of the first member 36. Further, the second member 37 is arranged in a state of being inclined so that the other end is located above the one end (that is, in a state of being inclined with a reverse gradient from the first member 36). The second member 37 has a position in which the other end (the left end in FIG. 5) is outside a predetermined distance from the other end of the entrance 301 in the width direction of the entrance and exit 301, and one end (the right end in FIG. 5). Has a length dimension at a position spaced apart from the other end of the first member 36 by a predetermined distance d.

  A distance d (a distance between the other end of the first member 36 and one end of the second member in the width direction of the doorway 301) d is provided at a position corresponding to the engaged portion 45 of the landing-side door panel 42, and The engaged portion 45 passes through the interval d when moving up and down 3. The engaged portion 45 of the present embodiment is engaged with the engagement device 39 of the car 3 when the car side door panel 32 is opened and closed by the power of the door opening and closing device 34 installed in the car 3. This power is transmitted to the landing-side door panel 42. Accordingly, the landing-side door panel 42 is opened and closed in synchronization with the opening and closing of the car-side door panel 32. In FIG. 5, the engaged portion 45 is schematically shown.

  The first member 36 and the second member 37 are positioned so as to sandwich the protruding portion 44 of the landing 4 when the car 3 stops (lands) at the landing 4 (see FIG. 4). That is, the protruding portion 44 of the landing 4 is located between the first member 36 and the second member 37 when the car 3 stops (lands) at the landing 4.

  Returning to FIG. 1, the counterweight 6 is connected to the car 3 via a rope 8 wound around a return wheel 10. Accordingly, the counterweight 6 moves up and down along the second guide rail 7 in accordance with the raising and lowering of the car 3 and in the opposite direction to the raising and lowering. Thus, the load of the hoisting machine 9 when raising / lowering the cage | basket | car 3 is suppressed because the counterweight 6 is connected with the cage | basket | car 3. FIG.

  The hoisting machine 9 has a traction sheave 14 and drives the rope 8 by the traction sheave 14 to raise and lower the car 3.

  The control panel 11 drives (controls) the hoisting machine 9 to move the car 3 up and down (up and down) along the first guide rail 5.

  The governor 12 stops the car 3 when the ascending / descending speed of the car 3 becomes a specified value or more.

  The shock absorber 13 reduces the impact when the car 3 descends and comes into contact.

  According to the elevator 1 described above, with the car 3 landing on the landing 4, the fall prevention unit 35 projects from the car 3 toward the landing 4 at a position lower than the lower end of the entrance 301. Thereby, the fall of the object from the clearance gap between the car side threshold 33 and the landing side threshold 43 at a landing position can be prevented.

  Moreover, since at least a part of the fall prevention unit 35 extends in a direction intersecting the horizontal direction, the fall prevention unit 35 is moved up and down by raising and lowering the car 3 as compared with the case where the entire fall prevention unit 35 extends in the horizontal direction. The escape path of the air pushed down or pushed up by the fall prevention part 35 between the fall prevention part 35 and the landing side threshold 43 when passing the vicinity of the landing side threshold 43 becomes large (refer FIG. 8). That is, when viewed from the direction from the car 3 to the landing 4, an air escape path between the landing side threshold 43 and the fall prevention unit 35 (see FIG. 8) except for a position where the landing side threshold 43 and the fall prevention unit 35 intersect. (See “Air escape”). Thereby, the buffing sound when the car 3 passes through the landing 4 is suppressed. In addition, in FIG. 8, the upper surface position of the landing side threshold 43 is shown with a dashed-two dotted line.

  Moreover, in the elevator 1 of this embodiment, the fall prevention part 35 has a plurality of members (a first member 36 and a second member 37) arranged at intervals in the horizontal direction. Each extends in a direction intersecting the horizontal direction (direction in which the landing side threshold 43 extends). For this reason, the air pushed down or pushed up by the fall prevention part 35 when the car 3 passes through the landing 4 at the time of ascending / descending is between a plurality of members (first member 36 and second member 37) (in FIG. 5). It is also possible to escape from the area indicated by the interval d). Thereby, the buffing sound is more effectively suppressed.

  Further, in the elevator 1 of the present embodiment, the landing 4 has the protruding portion 44. For this reason, in the gap between the car-side sill 33 and the landing-side sill 43 at the landing position, the first member 36 and the second member 37 are blocked by the protruding portion 44 (see FIG. 4). This makes it possible to more reliably prevent objects such as keys from falling from the gap between the car-side sill 33 and the landing-side sill 43 when the elevator passenger enters and leaves the car 3.

  In addition, the elevator of this invention is not limited to the said embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention. For example, the configuration of another embodiment can be added to the configuration of a certain embodiment, and a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of an embodiment can be deleted.

  In the elevator 1 of the above-described embodiment, the fall prevention unit 35 is disposed in the car 3, but is not limited to this configuration. The fall prevention unit 35 may be provided at the landing 4. In this case, the fall prevention unit 35 may be provided at each of the plurality of landings 4 or may be provided only at the predetermined landings 4. Even when the fall prevention unit 35 is provided only at the predetermined landing 4, at least buffing noise when the car 3 passes through the landing 4 provided with the fall prevention unit 35 is suppressed.

  In the elevator 1 of the above-described embodiment, the entire fall prevention unit 35 (the first member 36 and the second member 37) extends in a direction intersecting the horizontal direction, but is not limited to this configuration. It is sufficient that at least a part of the fall prevention unit 35 extends in a direction intersecting the horizontal direction. For example, when the fall prevention part 35 is comprised by one member, the part containing the edge part of a longitudinal direction may cross | intersect a horizontal direction as shown in FIG. 9, and a longitudinal direction is shown in FIG. The central part may be in a shape intersecting the horizontal direction. Further, when the fall prevention unit 35 is constituted by a plurality of members, as shown in FIG. 11, a part of the members (in the example shown in FIG. 11, the second member 37) coincides with the horizontal direction, These members (in the example shown in FIG. 11, the first member 36) may be arranged so as to intersect the horizontal direction. Even in these configurations, the part (member) extending in the direction intersecting the horizontal direction is pushed down by the fall prevention part 35 when the fall prevention part 35 passes near the landing side sill 43 by raising and lowering the car 3 or Since the escape route of the pushed-up air becomes larger, the buffing sound can be suppressed as compared with the case where the whole extends in the horizontal direction. 9 and 10, the upper surface position of the landing side threshold 43 is indicated by a two-dot chain line. 11 and the following FIGS. 12 to 14, the fall prevention unit 35 (including the first member 36, the second member 37, and the plurality of members 351 to 354) is attached to the plate-like member 31. Is schematically shown.

  Moreover, in the elevator 1 of the said embodiment, although the fall prevention part 35 is comprised by two members, the 1st member 36 and the 2nd member 37, it is not limited to this structure. Fall prevention part 35 may be constituted by one member (refer to Drawing 8-Drawing 10), and may be constituted by three or more members (in the example shown in Drawing 12, four members 351-354). .

  Moreover, in the elevator 1 of the said embodiment, in the fall prevention part 35, although each members 36 and 37 are extended straight in one direction, it is not limited to this structure. For example, as shown in FIGS. 13 and 14, the fall prevention unit 35 may have a continuously curved or bent shape. In this case, a buffing sound may occur at the bent portion 355 or the top portion 356 or the bottom portion 357 of the bent portion. However, the fall prevention portion 35 is divided (configured by a plurality of members) to bend the bent portion 355, the top portion 356, and the bottom portion 357. By forming a gap (interval between members) in a region corresponding to (see FIG. 12), air escapes from the gap, so that buffing is further suppressed.

  In the elevator 1 of the above-described embodiment, the car 3 is provided with the plate-like member 31 such as a fascia plate or a toe guard, but is not limited to this configuration. The car 3 may not have a plate-like member 31 such as a Fescher plate or a toe guard, and the platform 4 may be provided with a plate-like member such as a fascia plate or a toe guard.

  The elevator 1 of the above-described embodiment is a so-called single-open elevator in which the car door panel 32 and the landing door panel 42 move toward one or the other in the width direction of the doors 301 and 41 to open and close the doors 301 and 41. However, it is not limited to this configuration. In the elevator 1, the car-side door panel 32 and the landing-side door panel 42 move from the center in the width direction to both ends of the doorways 301 and 41, respectively, or move from both ends in the width direction toward the center, respectively. , 41 may be a so-called double-open elevator.
