Description

  The present invention relates to an elevator and an elevator sill closing device.

  In the elevator, a gap is provided between the landing side sill and the car side sill in order to prevent contact between the landing side sill and the car side sill when landing on the car landing. The size of the gap (running clearance) between the front end of the landing side sill and the front end of the car side sill causes a wheel trip, a wheelchair, a bed roller, a stroller, or the like.

  Conventionally, it is required to narrow the gap between the front end of the landing side threshold and the front end of the car side threshold. In order to adjust the size of the gap, the length of the landing side sill protruding to the hoistway side is adjusted. In order to reduce the size to 0, there is known a sill gap blocking device that tilts a blocking plate that closes the gap when landing from the car side to the landing side (see, for example, Patent Document 1).

  Hereinafter, an elevator and an elevator sill closing device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9. In the drawings, the same portions are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 is a schematic configuration diagram of an elevator according to an embodiment of the present invention. The elevator according to the present embodiment includes a car 4 and a counterweight 5 arranged in the hoistway 3. A machine room 6 is provided above the hoistway 3, and a hoisting machine 7 that drives a main rope 9 is installed in the machine room 6. Furthermore, the elevator is provided with an elevator control unit 8 that controls the operation of the car 4, and the elevator control unit 8 controls the hoisting machine 7 in response to the landing call or the car call, and the car 4 is called. Land the car 4 on the floor.

  In the elevator according to the present embodiment, an entrance / exit 12 that leads to the car 4 in the hoistway 3 is provided at a landing 11 provided on each floor of the building. The elevator is provided with a landing door 2 at the entrance 12. The landing door 2 engages with the car door 25 provided at the entrance 24 of the car 4 when the car 4 is landed, and opens and closes in conjunction with the opening and closing of the car door 25.

  FIG. 2 is a front view of the car door 25 provided at the entrance / exit 24 of the car 4 as seen from the landing 11 side. The car door 25 is a one-side opening method in which the two door panels 25a and 25b are opened in the same direction (leftward in the figure). The upper portions of these two door panels 25a and 25b are connected to the door opening / closing mechanism 27 via hangers (door hangers) 26a and 26b. The door opening / closing mechanism 27 drives the belt 100 to open and close the door panels 25a and 25b in the left-right direction.

  The door opening / closing mechanism 27 is a well-known one, and its structural description is omitted, but the two door panels 25a and 25b are interlocked with each other through the belt 100 and rollers by the power of a motor (not shown). The door opening / closing mechanism 27 opens and closes the door panels 25a and 25b in the left-right direction along the horizontal guide rail. The car 4 has a car-side sill 31 below the door panels 25a and 25b. The two door panels 25a and 25b constituting the car door 25 described above are slidably guided along the opening and closing direction thereof.

  FIG. 3 is a perspective view showing details of a car door portion of the elevator according to the present embodiment. The above described symbols represent the same elements.

  The elevator according to the present embodiment has a car 4 having a doorway 24, a car door 25 (door panels 25a, 25b) for opening and closing the doorway 24, and a car side sill 31 provided along the frontage direction of the doorway 24 (FIG. 1). ), And the landing door 2 (FIG. 1) facing by landing of the car 4 is guided in the door opening / closing direction, and has a car side threshold 31 and a hall side threshold 32 for each floor facing each other with a gap. Yes.

  Furthermore, the elevator has one side in the plate length direction pivotally supported by the car side sill 31 and the other side bridged on the landing side sill 32 facing this one side with a plate width larger than the dimension of the gap (running clearance). A closing plate 35 is provided. Further, the elevator according to the present embodiment rotates the other side of the closing plate 35 to a closed state in which the gap is closed by closing the door, and allows the rotation from the landing side sill to the non-contact standing state by opening the door. An operating mechanism 37 and a detector 50 that detects the closed state and the standing state of the closing plate 35 by the operating mechanism 37 are provided.

  The car side sill 31 is provided on the lower side of the entrance 24. The car side sill 31 is engaged with the lower ends of the two door panels 25a and 25b (shown broken in FIG. 3 to prevent complication) by guide grooves formed on the upper surface thereof. The panels 25a and 25b are guided along the opening / closing direction.

  A landing side threshold 32 is provided on the landing 11 side with respect to the car side threshold 31. The landing side sill 32 is disposed opposite to one side surface (front side surface in FIG. 3) of the car side sill 31 with a predetermined dimension (running clearance). A guide groove is also formed on the upper surface of the landing side sill 32, and the landing door 2 shown in FIG. 1 is slidably guided along the door opening / closing direction. The landing door 2 is also of a single-opening type having two door panels (not shown), and when the car 4 reaches the landing 11, it engages with the car door 25 and opens and closes together with the car door 25. .

  The closing plate 35 of FIG. 3 is provided on the car side sill 31. The closing plate 35 is larger than the length corresponding to the width dimension of the entrance / exit 24 of the car 4 (left and right direction in FIG. 2) and the facing distance between the car side sill 31 and the landing side sill 32 (that is, a gap generated therebetween). Have a width. Then, one side along the length direction is pivotally supported on the upper surface of the car side sill 31 via a support shaft (shown in FIG. 5) 36.

  FIG. 4 is an enlarged perspective view showing the standing state of the closing plate 35. FIG. 5 is an enlarged perspective view showing the closed state of the closing plate 35. The above described symbols represent the same elements.

  As shown in FIGS. 3 and 4, the closing plate 35 is in two states: a standing state in which the plate surface stands substantially vertically and a closing state in which the plate surface is substantially horizontal as shown in FIG. Thus, it pivots about the support shaft 36. In the closed state described above, the other side along the length direction is bridged onto the landing-side sill 32 that is the opponent and blocks the gap.

  The operating mechanism 37 changes the rotation position of the closing plate 35. The actuating mechanism 37 allows the closing plate 35 to turn to the upright state by the closing operation of the car door 25, and allows the turning to the state in which the opposing interval is closed by the opening operation of the car door 25. As shown in FIGS. 3 to 5, the operating mechanism 37 is formed by a combination of an operating body 371 integrally provided at one end (right end in the drawing) in the length direction of the closing plate 35 and a weight 38 positioned above the operating body 371. Composed.

  FIG. 6A and FIG. 6B are a plurality of views showing a first example of the elevator operating mechanism 37 and the detector 50 according to the present embodiment. The above described symbols represent the same elements.

  The actuating body 371 is a plate piece formed by bending the closing plate 35 obtusely along the middle line in the plate length direction. The operating body 371 is biased downward by a weight 38 provided above the plate surface of the operating body 371. The weight 38 is provided so as to be movable up and down, and the actuating body 371 rotates the closing plate 35 in two states, a closed state and an upright state, along with the vertical movement of the weight 38.

  That is, when the weight 38 is lowered, the weight 38 comes into contact with the plate surface of the operating body 371, and the weight 38 pushes down the plate surface. For this reason, the closing plate 35 integrated with the operating body 371 rotates clockwise about the support shaft 36, and the plate surface stands up almost vertically as shown in FIGS. 3, 4 and 6B. It becomes the standing state.

  The clockwise direction refers to the direction of rotation viewed from the direction of arrow C in FIGS. In the standing state of the operating body 371, the rotation angle by the support shaft 36 may exceed 90 degrees. The rotation angle of the operating body 371 in the standing state is determined by the attitude of the operating body 371 so that the operating body 371 does not protrude into the gap between the car side sill 31 and the landing side sill 32. The rotation angle is determined so that the operating body 371 does not protrude from the gap and the car side sill 31 and the landing side sill 32 do not contact each other and do not interfere with each other when the car 4 is traveling.

  On the other hand, the weight 38 is removed from the plate surface of the operating body 371 by the rising of the weight 38. For this reason, the closing plate 35 integrated with the actuating body 371 rotates counterclockwise around the support shaft 36 due to its own weight. For this reason, as shown in FIG. 5, the other side along the length direction of the closing plate 35 is placed on the landing side sill 32 serving as the opponent, and the other side becomes substantially horizontal. The state of the closing plate 35 is a gap closing state.

  Further, the operating mechanism 37 is provided with a weight raising / lowering mechanism 41 for moving the weight 38 up and down as shown in FIG. The weight raising / lowering mechanism 41 includes a guide cylinder 41a (guide), a connecting string 41b, and a turning pulley 41c. The guide cylinder 41 a is provided vertically above the plate surface of the operating body 371. The guide cylinder 41a guides the weight 38 so that the weight 38 can freely move up and down inside the guide cylinder 41a. As shown in FIG. 3, one end of the connection string 41b is connected to the weight 38 in the guide cylinder 41a, and the other end is connected to a bracket 42 that is integrally connected to the hanger 26a. The turning pulley 41c is provided above the guide tube 41a and changes the operating direction of the connecting string 41b to substantially a right angle.

  Here, the length of the connecting string 41b is set as follows. That is, when the car door 25 provided at the entrance / exit of the car 4 is in a closed state, the bracket 42 is located on the rightmost side as shown in FIG. At this time, as shown in FIGS. 3 and 4, the weight 38 is at the bottom dead center position, and the length of the connecting string 41 b is set so that the plate surface of the operating body 371 is pushed down. With these configurations, the weight lifting mechanism 41 raises the weight 38 with the opening operation of the car door 25 and lowers it with the closing operation of the door 25.

  That is, the operating mechanism 37 is provided above the car door 25 in the horizontal direction, and moves vertically in the fully open direction when the door is opened, and moves in the fully closed direction when the door is closed, and vertically on one end in the plate length direction of the closing plate 35. A provided guide cylinder 41a and a weight 38 that urges the operating body 371 (one side of the closing plate 35) downward in the lower part moved by the guide cylinder 41a. The operating mechanism 37 has a connection string 41b (cord) having one end connected to the weight 38 and the other end connected to the hanger 26a, and a guide for converting the moving direction of the connection string 41b between the horizontal direction and the vertical direction. A connecting pulley 41c (pulley) provided above the cylinder 41a is provided, and the connecting string 41b raises the weight 38 by opening the door and lowers the weight 38 by closing the door.

  The detector 50 is a contact switch in the examples of FIGS. 6 (a) and 6 (b). The detector 50 is in contact with the first contact 51 provided on the back surface side of the closing plate 35 and the first contact 51 provided on the car side sill 31 in the standing state, and is separated from the first contact 51 in the closed state. A second contact 52, a current meter 53, and an output unit 54 that outputs a value indicating the presence or absence of power feeding and energization between the contacts 51 and 52 according to the value of the meter 53.

  Further, the elevator control unit 8 in FIG. 1 temporarily stops the start of traveling of the car 4 by a signal indicating the closed state from the detector 50. The car 4 is provided with a car control device 101, and the elevator control unit 8 can exchange control signals with the car control device 101 via the tail cord 102.

  Moreover, the elevator which concerns on this embodiment may use a various sensor for a detector.

  FIGS. 7A and 7B are a plurality of views showing a second example of the elevator operating mechanism 37 and the detector according to the present embodiment. The above described symbols represent the same elements. The detector 55 may be a photoelectric sensor.

  The detector 55 is provided on the car-side sill 31 and has a light projector 56 with the optical axis directed to the other side of the closing plate 35; a light-receiver 57 that is provided on the car-side sill 31 and receives reflected light of the optical axis; And an output unit 58 that outputs a value indicating whether or not the light receiver 57 receives light. The projector 56 may use a laser light source having a wavelength in the visible light band. The light receiver 57 may use a light receiving element corresponding to the light emission band. The detector 55 may include a lens for collecting light, a mirror, and the like.

  Or the detector 55 may be comprised by the output part which outputs the value which shows the presence or absence of reception of a reflected wave, the receiver of an ultrasonic wave, the reflected wave of an ultrasonic wave.

  FIGS. 8A and 8B are a plurality of views showing a third example of the elevator operating mechanism 37 and the detector according to the present embodiment. The above described symbols represent the same elements. The detector 60 may be a sensor that detects lines of magnetic force.

  The detector 60 includes a magnetic generator 61 that generates a loop of magnetic lines H in a direction that penetrates the other side of the closing plate 35, and an output unit 62 that outputs a value corresponding to the degree of change in the strength of the magnetic field due to the magnetic lines of force H. It may be provided with.

  The elevator according to the present embodiment may be provided with a belt-like load member 39 that promotes rotation to the closed position as shown in FIGS. 3 and 4 on the back surface of the closing plate 35. The load member 39 promotes counterclockwise rotation of the closing plate 35 due to its own weight when the weight 38 is lifted, and can be rotated more reliably.

  Next, the operation of the elevator according to this embodiment having the above-described configuration will be described.

  When the car door 25 provided at the entrance / exit 24 of the car 4 is in a closed state, the bracket 42 is located on the rightmost side as shown in FIG. At this time, the weight 38 connected to the bracket 42 via the connecting string 41b has moved to the bottom dead center position, and the operating body 371 is pushed down. For this reason, the closing plate 35 integrated with the actuating body 371 is in an upright state, and does not hinder the raising and lowering of the car 4.

  FIG. 9A is a perspective view showing a standing state detected by the detector 50. The above described symbols represent the same elements. In the figure, the example is changed as appropriate when viewed from the opposite direction to the perspective direction of FIG. In the elevator according to the present embodiment, a pair of detectors 50 may be provided in the door opening / closing direction.

  The detector 50 provided in the car-side sill 31 continues to detect ON when the closing plate 35 is accommodated on the car 4 side. The elevator control unit 8 determines that it is in a safe state because the closing plate 35 is erected by receiving the ON signal from the detector 50. The elevator controller 8 accepts a car call or a hall call only while receiving an ON signal. The elevator control unit 8 causes the car 4 to travel to the destination floor and opens the door on the destination floor.

  On the other hand, when the car 4 is landed on a predetermined floor and the door door opening / closing mechanism 27 opens the car door 25 in the direction of arrow A in FIG. 3, the bracket 42 causes the connecting string 41b and the turning pulley 41c to move. Through the direction of arrow B in FIG. For this reason, the weight 38 is guided by the guide cylinder 41a from the state of FIGS. As the weight 38 rises, the pressing force to the plate surface of the operating body 371 is released, so that the operating body 371 and the closing plate 35 rotate counterclockwise around the support shaft 36 by their own weight. And as shown in FIG. 5, the other side along the length direction of the closing board 35 is mounted on the landing side sill 32 which becomes an other party, becomes substantially horizontal, and will be in a gap closing state.

  The rotation operation of the closing plate 35 in the closing direction is completed with a slight operation stroke in which the weight 38 is released from the plate surface of the operating body 371. That is, when the door panel 25a of the car door 25 does not allow personnel to pass through, for example, about 125 mm, the door panel 25a slightly opens, so that the closing operation by the closing plate 35 is completed and the gap between the sills 31 and 32 is blocked. It becomes possible.

  Thereafter, the door panels 25a and 25b continue to open until they are fully opened. During this time, the weight 38 continues to be pulled up in the guide tube 41a by the connecting string 41b, but is closed from the operating body 371. The plate 35 continues to close the gap between the thresholds 31 and 32 without changing from the closed state shown in FIG. For this reason, passengers can enter and exit as the doors open, and vehicles such as carts can enter and exit smoothly, improving safety.

  On the other hand, when the car door 25 is closed, the bracket 42 moves to the right in the drawing in accordance with the door closing operation, so that the weight 38 is lowered. At this time, since the weight 38 is located above the plate surface of the operating body 371 in the state of FIG. 5, the closing plate 35 maintains the closing state shown in FIG. When the weight 38 comes into contact with the plate surface of the operating body 371 and pushes down the plate surface, the closing plate 35 starts to rotate clockwise. That is, when the car door 25 starts to close, the closing plate 35 maintains a substantially horizontal gap closing state, and when the car door 25 is closed to a slight opening width of, for example, about 125 mm, the closing plate cannot be passed for the first time. 35 starts the clockwise rotation shown in the figure. When the door 25 is fully closed, the closing plate 35 is erected almost vertically as shown in FIGS. 3 and 4, and the car 4 can be moved up and down.

  FIG. 9B is a perspective view showing a detection state of the closed state by the detector 50. The above described symbols represent the same elements. The detector 50 continues to detect OFF when the closing plate 35 is bridged onto the landing side threshold 32. The elevator control unit 8 determines that the car 4 is in a stopped state by bridging the closing plate 35 based on the OFF signal from the detector 50.

  After the elevator control unit 8 sends a door closing signal of the car 4 to the car 4, while the off signal is received from the detector 50, it is determined that the position of the closing plate 35 has not yet returned. While the ON signal is not received from the detector 50, the elevator control unit 8 does not run the car 4. In this case, when a person presses the open button on the landing device of the landing 11, the elevator control unit 8 immediately opens the car 4. There is no confinement. Moreover, when the attitude | position of the closing board 35 returns to normal and the detector 50 sends an ON signal to the elevator control part 8, the elevator control part 8 will restart the operation | movement of the car 4. FIG.

  As described above, when the car door 25 opens or closes, the opening or closing operation with a slight opening width that cannot be passed by a person can cause a gap between the sills 31 and 32 by the closing plate 35. The gap closing operation is completed.

  Further, since the detector 50 detects the closed state in which the opposing gap between the car-side sill 31 and the landing-side sill 32 is closed, and the standing state of the closing plate 35, the closing plate 35 is on the landing 11 side. It is avoided that the car 4 moves up and down while falling down. A detector 50 provided in the vicinity of the closing plate 35 is provided, and the elevator controller 8 monitors the output of the detector 50, thereby detecting a malfunction of the closing plate 35 according to the value of the output signal of the detector 50. Will be able to.

  In addition, because the opening width allows personnel to pass through, even if personnel or trolleys enter or leave the car 4 while the door is being opened or closed, at this point, the closing plate 35 is in a substantially horizontal gap closing state. It has become. Therefore, unlike the conventional example, the door does not get caught on the shielding panel during the closing operation due to the doorway opening and closing, and the door can be smoothly moved in and out, and the safety is greatly improved.

  If the gap is left open, for example, a stick used by elderly people, the tip of an umbrella, the heel of a shoe may be caught, or a wheelchair, bed roller, or stroller tire may be removed. According to the elevator according to the present embodiment, it is possible to prevent the occurrence of a failure by the closing plate 35, and it is possible to eliminate the possibility that the article falls into the pit from the gap. It can meet the demand for barrier-free. In addition, since the operation of the closing plate 35 is constantly monitored by the detector 50, a failure of the device due to a malfunction of the detector 50 does not occur.

  Therefore, according to the elevator according to the present embodiment, it is possible to safely detect when the car 4 is traveling and to block the gap between the landing side sill 32 and the car side sill 31 when the car is landing. Become.

  In the above-described embodiment, the closing plate 35 is attached to the car-side sill 31, but of course, the closing plate 35 may be attached to the opposite landing-side sill 32 and closed in the same manner as the landing door 2 is opened and closed. . However, in this case, the closing plate 35 and the weight lifting mechanism 41 must be provided for each floor. In this case, the detectors 50, 55 and 60 electrically send signals to the elevator control unit 8 via cables wired in the building.

  Moreover, although the single door type door which consists of two door panels was illustrated, it can apply similarly to the system which opens and closes the door panel of several sheets, and the system which opens and closes one door panel.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
