Description

  The present invention relates to an elevator including a member for closing a space between a car side sill and a landing side sill.

  In general, in an elevator, a gap is provided between the car side sill and the landing side sill in order to prevent them from contacting each other. However, when the user gets on and off the car, there is a possibility that an object is dropped into the hoistway from this gap. In order to prevent such an object from falling into the hoistway, there is known an elevator including a member that closes a space between the car side sill and the landing side sill (see, for example, Patent Document 1). This elevator has a platform and a car. The platform has a platform side threshold. The car includes a car side sill, a car door, an advance / retreat member, and an urging member (spring). The advancing / retreating member advances / retreats between an advance position that closes between the car-side sill and the landing-side sill and a retreat position that is separated from the landing-side sill toward the car-side sill. When the car door is opened, the advancing / retracting member pushes the advancing / retreating member toward the landing side, so that the advancing / retreating member advances to the advance position. When the car door is separated from the advance / retreat member when the door is closed, the urging member pushes the advance / retreat member into the retracted position. Thereby, the advance / retreat member is retracted to the retracted position.

JP 2014-69960 A

  However, in the elevator, if the urging member fails when the advance / retreat member is in the advanced position, the advance / retreat member cannot be retracted, and the advance / retreat member remains in the advanced position. When the car moves up and down in this state, for example, the tip of the advance / retreat member may come into contact with the landing side sill.

  An object of the present invention is to provide an elevator that can prevent a car from going up and down while advancing and retracting members that block between a car side sill and a landing side sill are advanced.

  The elevator according to the present invention includes a car door, a car that extends horizontally below the car door, and has a car-side sill that guides the car door in the opening and closing direction, and the same as the car-side sill at the lower end of a landing doorway. An elevator having a platform-side sill extending in a direction, wherein the car extends in the same direction as the car-side sill and extends between the car-side sill and the platform-side sill And an advancing / retreating member that advances / retreats with respect to the platform-side sill on the side of the car-side sill, and an elastic deformation that accompanies the advancing / retreating member retracting from the advancement position to the retraction position. When the urging force is generated or increased, the urging member that urges the advancing / retreating member toward the advanced position when the advancing / retreating member is in the retracted position, is in contact with the advancing / retreating member The car door includes a pressing portion that presses the advance / retreat member toward the retracted position when the car door is closed, and the car door is in contact with the advance / retreat member when fully closed and is fully open. And a contact portion disposed at a position separated from the advance / retreat member.

  According to such a configuration, when the car door is in the fully open state, the abutting portion is separated from the advance / retreat member, so that the advance / retreat member advances to the advance position by the urging by the urging member. As a result, the advancing / retreating member closes the space between the car side threshold and the landing side threshold. Moreover, even if the urging member breaks down when the advance / retreat member is in the advanced position, the advance / retreat member is pushed toward the retreat position by the pressing portion of the abutment portion and retreats when the car door is closed. It is possible to prevent the car from moving up and down while the advancing and retracting member closing the space between the car side sill and the landing side sill remains in the advanced position.

  In the elevator, the contact portion may include an extending portion extending in a door opening direction from an end portion of the pressing portion on a door opening side.

  According to this configuration, when the car door is closed, after the pressing portion of the contact portion presses the advance / retreat member toward the retracted position, the extension portion of the contact portion contacts the advance / retreat member. Therefore, in the fully closed state of the car door, the advancing / retreating member is stably held in a state of being in contact with the extending portion. Thereby, even if a car vibrates in this fully closed state, it can suppress that an advance / retreat member advances to an advance position.

  In the elevator, the advance / retreat member may include a roller that is disposed at a position pressed by the pressing portion and that has a rotation center in the vertical direction.

  According to this structure, since the site | part pressed by the press part in an advance / retreat member is a roller, the resistance at the time of opening and closing of a car door in the state which the press part contacted the advance / retreat member can be suppressed.

  The elevator includes a linear motion mechanism to which the advancing / retracting member can be attached, the car has a car doorway, and a car body in which the car side sill is disposed at a lower end of the car doorway, The moving mechanism includes a base portion fixed to the car body, a table portion to which the advance / retreat member is fixed and slides in the advance / retreat direction of the advance / retreat member with respect to the base portion, the base portion, and the table portion And a bearing that rotates as the table portion slides relative to the base portion.

  According to this configuration, since the advance / retreat member is attached to the linear motion mechanism that is slidable by the bearing, the advance / retreat member smoothly advances / retreats.

  Another elevator according to the present invention includes a landing door, a landing that extends horizontally below the landing door, and has a landing-side threshold that guides the landing door in the opening and closing direction, and the landing-side threshold at a lower end of a car entrance. And an elevator having a car-side sill extending in the same direction, the landing extending in the same direction as the landing-side sill, and closing between the car-side sill and the landing-side sill An advancing / retreating member that advances / retreats between an advancing position and a retreating position that is separated from the car-side sill on the side of the landing side sill, and elasticity that accompanies the retreating member retracting from the advancing position to the retreating position An urging member that urges the advancing / retreating member toward the advanced position when the urging force is generated or increased by the deformation and the advancing / retreating member is at the retracted position; A pressing portion that presses the advancing / retracting member toward the retracted position when the landing door is closed in contact with a material, and the landing door is in contact with the advancing / retreating member when fully closed. And an abutting portion disposed at a position separated from the advance / retreat member when in the fully open state.

  According to such a configuration, when the landing door is in the fully open state, the abutting portion is separated from the advance / retreat member, so that the advance / retreat member advances to the advance position by urging by the urging member. As a result, the advancing / retreating member closes the space between the car side threshold and the landing side threshold. Moreover, even if the urging member breaks down when the advance / retreat member is in the advanced position, the advance / retreat member is pushed toward the retreat position by the pressing portion of the contact portion and retreats when the landing door is closed. It is possible to prevent the car from moving up and down while the advancing / retracting member closing the space between the car side sill and the landing side sill is advanced.

  Hereinafter, an embodiment of an elevator according to the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the elevator according to this embodiment includes a hoistway 2 extending in the Z-axis direction (vertical direction) in a building, a landing 3 provided on a predetermined floor of the building, and the hoistway 2. And a car 4 that moves up and down and stops at the landing 3.

  The landing 3 includes a landing entrance 31, a landing side threshold 32 extending in the X-axis direction at the lower end of the landing entrance 31, and a landing door 33.

  The landing side threshold 32 is disposed at the front end of the floor at the landing entrance 31 (the front end on the hoistway 2 side). The landing door 33 of the present embodiment has a rectangular plate shape and there are two. Moreover, the landing door 33 of this embodiment is a double-open door, and is opened and closed in the X-axis direction (the horizontal direction in FIGS. 2 to 4).

  The car 4 extends in the X-axis direction (the horizontal direction in FIGS. 2 to 4 (the same direction as the direction in which the landing side sill 32 extends)) below the car door 41 (see FIGS. 1 and 2). And a car side sill 42 having a guide groove (not shown) extending in the X-axis direction. The car 4 of the present embodiment includes a car doorway 43, and a car body 44 in which the car side sill 42 is disposed at the lower end of the car doorway 43, and a connection portion 45 that fixes the car side sill 42 and the car body 44. (See FIGS. 8 to 13). Moreover, the cage | basket | car 4 is provided with the advancing / retreating member 5, the compression spring (biasing member) 6, and the contact part 7, as shown in FIG. 3, FIG. Furthermore, the car 4 of this embodiment includes a linear motion mechanism 8 (see FIGS. 10 and 11).

  The car door 41 of the present embodiment has a rectangular plate shape. In the car door 41 of the present embodiment, the main surface (rectangular surface) on the landing 3 side and the surface opposite to the landing 3 side (rectangular surface) are both flat. The car door 41 of the present embodiment is arranged in a state where the long side is along the Z-axis direction (vertical direction in FIG. 1) and the lower end portion thereof is arranged in the guide groove of the car side sill 42. When the lower end portion of the car door 41 arranged in this manner slides, the opening and closing of the car door 41 is guided by the guide groove.

  There are two car doors 41 according to this embodiment. The pair of car doors 41 are double doors. Specifically, the pair of car doors 41 moves outward in the X-axis direction so as to be separated from each other when the door is opened, and moves inward in the X-axis direction so as to approach each other when the door is closed (see FIG. 2). ). Therefore, in the right car door 41, the door opening direction is a direction toward the right, and the door closing direction is a direction toward the left. Further, in the left car door 41, the door opening direction is a direction toward the left, and the door closing direction is a direction toward the right.

  The car side sill 42 is disposed at the front end of the car entrance 43 on the floor platform 3 side.

  The advancing / retreating member 5 extends in the X-axis direction (the same direction as the direction in which the car-side sill 42 extends), and advances between the landing-side sill 32 and the car-side sill 42 (see FIG. 4), and the landing side. It is a member that advances and retreats between a retreat position (see FIG. 3) separated from the sill 32 toward the car side sill 42. The upper surface of the advancing / retreating member 5 at the advanced position is located at substantially the same height as the upper surface of the car side sill 42. Further, when the advance / retreat member 5 is retracted from the advanced position to the retracted position, the advance / retreat member 5 is slid and stored below the car side sill 42. The advance / retreat member 5 of this embodiment is attached to the linear motion mechanism 8.

  As shown in FIGS. 8 to 13, the advance / retreat member 5 of this embodiment includes a bent plate-like member and a roller 55. Since the advance / retreat member 5 has a bent plate-like member (that is, a hollow member), the advance / retreat member 5 can be reduced in weight. Specifically, the advancing / retreating member 5 includes a blocking portion 51 that closes the space between the car-side sill 42 and the landing-side sill 32 when in the advanced position, and a front end of the blocking portion 51 (on the landing-side sill 32 side of the blocking portion 51. A first extending portion 52 extending downward from the end edge), a second extending portion 53 extending in the retracting direction of the advancing and retracting member 5 from the tip of the first extending portion 52 (the lower end of the first extending portion 52), A third extension portion 54 extending downward from a tip of the second extension portion 53 (an edge of the second extension portion 53 on the retracting direction side of the advance / retreat member 5), and a roller attached to the second extension portion 53 55.

  The blocking portion 51 is a plate-like portion extending in the X-axis direction (horizontal direction) and the Y-axis direction (advancing / retreating direction of the advance / retreat member 5). Further, when the blocking portion 51 is in the advanced position, it is sufficient that at least a part between the car side threshold 42 and the landing side threshold 32 is blocked. However, the closed portion 51 of the present embodiment is in the advanced position. At some point, the entire space between the car side threshold 42 and the landing side threshold 32 is blocked. The second extending portion 53 is placed on the linear motion mechanism 8 (see FIGS. 10 and 11).

  The roller 55 is disposed at a position pressed by a pressing portion 71 of the contact portion 7 described later, and has a Z-axis direction (vertical direction) as a rotation center. There are at least one roller 55, but there are two rollers 55 of the present embodiment. Each of the rollers 55 is attached to the lower surface of the second extending portion 53 of the advance / retreat member 5. For example, the distance between each of the rollers 55 and the central axis α in the X-axis direction (horizontal direction) of the advance / retreat member 5 is equal.

  As shown in FIGS. 12 and 13, the compression spring 6 of the present embodiment includes a bracket 61 fixed to the second extending portion 53 of the advance / retreat member 5, and a bracket 62 fixed to a part of the connecting portion 45. It is provided between.

  Since the bracket 61 is fixed to the second extending portion 53 of the advance / retreat member 5, the bracket 61 moves in the advance / retreat direction (horizontal direction (left / right direction) in FIG. ) The connecting portion 45 to which the bracket 62 is fixed fixes the car side sill 42 and the car main body 44. Even if the advance / retreat member 5 moves in the advance / retreat direction, the car side sill 42 and the car main body 44 do not move in this advance / retreat direction, so the bracket 62 does not move in this advance / retreat direction.

  Thus, when the advance / retreat member 5 advances / retreats, the bracket 61 moves and the bracket 62 does not move, so the width between the brackets 61, 62 (the distance in the advance / retreat direction of the advance / retreat member 5 between the brackets 61, 62) changes. To do. As a result, the compression spring 6 is elastically deformed in this advance / retreat direction (Y-axis direction) in accordance with the advance / retreat of the advance / retreat member 5. Due to this elastic deformation, a biasing force is generated in the compression spring 6 or the biasing force of the compression spring 6 is increased.

  Further, when the advance / retreat member 5 is in the retracted position (see FIG. 12), the compression spring 6 biases the advance / retreat member 5 toward the advanced position (rightward in the figure). Further, even when the advance / retreat member 5 is in the advanced position (see FIG. 13), the compression spring 6 urges the advance / retreat member 5 toward the advanced position (rightward in the figure). For this reason, even if the elasticity of the compression spring 6 is somewhat weakened, the advance / retreat member 5 is reliably pushed out to the advanced position.

  Although at least one compression spring 6 exists, there are two compression springs 6 of the present embodiment. Specifically, one compression spring 6 is disposed at an end portion of one car door 41 in the door closing direction, and the other compression spring 6 is disposed at an end portion of the other car door 41 in the door closing direction. (See FIG. 2). Thereby, the compression spring 6 is arrange | positioned at intervals in the opening / closing direction of the car door 41. For example, the interval between each compression spring 6 and the central axis α in the X-axis direction (horizontal direction) of the advance / retreat member 5 is equal. The two compression springs 6 are both arranged closer to the door closing direction than the linear motion mechanism 8.

  In the car door 41, the abutting portion 7 is disposed at a position that abuts the advancing / retreating member 5 when the car door 41 is in the fully closed state and is separated from the advancing / retreating member 5 when the car door 41 is fully opened. The contact portion 7 has a pressing portion 71 that can press the advance / retreat member 5. The contact portion 7 of the present embodiment has an extending portion 73 that extends from the end portion 72 on the door opening side of the pressing portion 71 in the door opening direction. Furthermore, since the contact part 7 of this embodiment is a hollow member as shown in sectional drawing of FIG. 8, weight reduction of the contact part 7 can be achieved.

  The pressing portion 71 approaches the inside of the car 2 as it goes in the door opening direction on the surface of the car door 41 opposite to the landing 3 (the surface of the main surface of the car door 41 opposite to the landing 3). That is, the pressing portion 71 is inclined with respect to the surface of the car door 41 opposite to the landing 3. Specifically, the pressing portion 71 is inclined so that the door closing direction is farther from the inside of the car and the door opening direction is closer to the inside of the car.

  The pressing portion 71 presses the advancing / retreating member 5 toward the retracted position when the car door 41 is closed in a state where it is in contact with the advancing / retreating member 5. Specifically, the pressing portion 71 presses the roller 55 of the advance / retreat member 5 toward the retracted position. The pressing portion 71 of the present embodiment is plate-shaped and has a slope shape when viewed in plan as in the plan views of FIGS. 3 and 4.

  The extending portion 73 is similarly plate-shaped and extends in the X-axis direction (horizontal direction) when viewed in plan. That is, the extension part 73 is not inclined with respect to the surface of the car door 41 opposite to the landing 3, and the distance between the extension part 73 and this surface is constant. In this embodiment, the extension part 73 and this surface are substantially parallel. Further, the extending portion 73 extends from the pressing portion 71 (that is, continues to the pressing portion 71), and the extending portion 73 is positioned closer to the door opening direction side of the car door 41 than the pressing portion 71. Therefore, when the car door 41 is closed, the roller 55 comes into contact with the extending portion 73 after being pressed by the pressing portion 71.

  There is at least one contact portion 7. There are two contact portions 7 in the present embodiment. Specifically, one abutting portion 7 is disposed at an end portion of one car door 41 in the door opening direction, and the other abutting portion 7 is disposed at an end portion of the other car door 41 in the door opening direction. (See FIG. 2). Thus, the abutting portion 7 is attached to the car door 41 at a distance from each other in the opening / closing direction of the car door 41. For example, the distance between each contact portion 7 and the central axis α in the X-axis direction (horizontal direction) of the advance / retreat member 5 is equal. The two abutting portions 7 are both arranged closer to the door opening direction than the linear motion mechanism 8.

  The linear motion mechanism 8 includes a base portion 81 fixed to the car body 44, a table portion 82 that slides in the Y-axis direction (advancing / retreating direction of the advance / retreat member 5), a base portion 81, and a table portion 82. And a bearing 83 (see FIG. 5).

  Specifically, as shown in the plan views of FIGS. 6 and 7, each of the base portion 81 and the table portion 82 has a rectangular plate shape in plan view. The base part 81 is fixed to the car body 44 via the connection part 45 (see FIGS. 10 and 11). The advance / retreat member 5 is fixed to the table portion 82. Specifically, the second extension portion 53 of the advance / retreat member 5 is fixed to the table portion 82 in a state where it is placed. The bearing 83 is rotatable as the table portion 82 slides with respect to the base portion 81. In the linear motion mechanism 8 of the present embodiment, when the advance / retreat member 5 is in the retracted position, the table portion 82 overlaps the base portion 81, and when the advance / retreat member 5 is in the advanced position, the table portion 82 with respect to the base portion 81. However, it will be in the state shifted | deviated to the platform 3 side (refer FIG. 10, FIG. 11).

  In the car 4 of this embodiment, there are two linear motion mechanisms 8. Further, the distance between each of the linear motion mechanisms 8 and the central axis α in the X-axis direction (horizontal direction) of the advance / retreat member 5 is equal.

  A stopper 84 is provided below the linear motion mechanism 8 at a position facing the third extending portion 54 of the advance / retreat member 5. In the car 4 of the present embodiment, when the advance / retreat member 5 is in the retracted position (see FIG. 10), the advance / retreat distance of the advance / retreat member 5 (the distance between the advanced position and the retracted position (in this embodiment, the landing side threshold 32). The distance from the car-side sill 42)) is equal to the distance between the third extending portion 54 of the advance / retreat member 5 and the stopper 84. Therefore, when the advancing / retracting member 5 advances to a position where the third extension portion 54 of the advancing / retreating member 5 and the stopper 84 come into contact with each other, the closing portion 51 of the advancing / retreating member 5 is entirely between the car side sill 42 and the landing side sill 32. Will be blocked.

  Hereinafter, the operation of the advancing / retreating member 5 and its surroundings when the car door 41 is opened and closed will be described together.

  When the car door 41 is in the fully open state, the advance / retreat member 5 is in the advanced position and closes the space between the car side sill 42 and the landing side sill 32. Further, in this state, the contact portion 7 is at a position separated from the advance / retreat member 5 in the X-axis direction.

  When the car door 41 is closed from the fully open state, the abutment portion 7 moves in the door closing direction in accordance with the movement of the car door 41. At this time, the distal end portion 74 (see FIG. 6) of the pressing portion 71 of the contact portion 7 approaches the advance / retreat member 5 and then contacts the roller 55 of the advance / retreat member 5. When the car door 41 is further moved in the door closing direction in a state where the pressing portion 71 and the roller 55 are in contact with each other, the abutting portion 7 is pressed toward the retracting direction of the advance / retreat member 5. As a result, the advance / retreat member 5 is retracted to the opposite side of the landing 3, that is, to the retracted position. At this time, in the plan view of FIG. 4, the left roller 55 rotates counterclockwise, and the right roller 55 rotates clockwise.

  Furthermore, after the roller 55 is pressed by the pressing portion 71, the roller 55 contacts the extending portion 73 of the contact portion 7. At this time, the advance / retreat member 5 stops retracting and is fixed at the retracted position.

  As the advance / retreat member 5 is retracted, the bracket 61 attached to the second extending portion 53 of the advance / retreat member 5 moves to the opposite side of the landing 3 in the Y-axis direction. At this time, the compression spring 6 is elastically deformed to urge toward the landing 3 side (advance position) (see FIG. 12). Therefore, when the advancing / retreating member 5 is loosely fixed by the contact portion 7, the advancing / retreating member 5 can be pushed toward the advance position.

  When the car door 41 is opened from the fully closed state, the abutting portion 7 moves in the door opening direction in accordance with the movement of the car door 41. Accordingly, the roller 55 comes into contact with the pressing portion 71 of the contact portion 7 after contacting the extended portion 73 of the contact portion 7. During this time, the roller 55 rotates in the opposite direction. Further, while the car door 41 is moving in the door opening direction and the roller 55 is in contact with the pressing portion 71, the advancing / retreating member 5 is gradually loosened by the contact portion 7 and the compression spring 6 is Gradually grow toward platform 3 (advance position). Thereby, the advance / retreat member 5 fixed to the compression spring 6 gradually advances toward the landing 3 side (advance position).

  Thereafter, when the contact portion 7 moves to a position separated from the roller 55 in the X-axis direction, the advance / retreat member 5 advances to the advance position. At this time, the position of the advancing / retracting member 5 is not restricted to other than the compression spring 6, and the movable member 5 can be freely moved except for the compression spring 6. The advancement / retraction member 5 according to the present embodiment stops when the third extending portion 54 of the advance / retreat member 5 comes into contact with a stopper 84 provided below the linear motion mechanism 8 (see FIG. 11).

  Hereinafter, the effect of the elevator 1 will be described.

  In the elevator 1 according to the present invention, when the car door 41 is fully opened, the contact portion 7 is separated from the advance / retreat member 5. Therefore, the advance / retreat member 5 advances to the advance position by the urging by the compression spring 6. Thereby, the advancing / retreating member 5 closes the space between the car side threshold 42 and the landing side threshold 32. Moreover, even if the compression spring 6 breaks down when the advance / retreat member 5 is in the advanced position, the advance / retreat member 5 is pressed toward the retracted position by the pressing portion 71 of the contact portion 7 when the car door 41 is closed. Evacuated. Thereby, it is possible to prevent the car 4 from moving up and down while the advancing / retracting member 5 closing the space between the car side threshold 42 and the landing side threshold 32 is advanced.

  In the elevator 1, when the car door 41 is closed, the pressing portion 71 of the contact portion 7 presses the advance / retreat member 5 toward the retracted position, and then the extension portion 73 of the contact portion 7 contacts the advance / retreat member 5. . Therefore, in the fully closed state of the car door 41, the advance / retreat member 5 is stably held while being in contact with the extending portion 73. Thereby, even if the cage | basket | car 4 vibrates in this fully closed state, it can suppress that the advancing / retreating member 5 advances to an advance position.

  In the elevator 1, the portion that is pressed by the pressing portion 71 in the advance / retreat member 5 is the roller 55, so that resistance when the car door 41 is opened and closed in a state where the press portion 71 is in contact with the advance / retreat member 5 can be suppressed.

  In the elevator 1, the advance / retreat member 5 is attached to the linear motion mechanism 8 slidable by the bearing 83, so that the advance / retreat member 5 is smoothly advanced and retracted.

  In the elevator 1, the advancing / retracting member 5 is advanced by the linear motion mechanism 8 in addition to the compression spring 6, so that it can be advanced at a uniform speed as compared with the case where the advance / retreat member 5 is advanced only by the compression spring 6.

  Further, in the elevator 1, the compression spring 6 and the linear motion mechanism 8 are arranged at equal intervals from the central axis α in the X-axis direction (horizontal direction) of the advance / retreat member 5. Therefore, the advancing / retreating member 5 is advanced at a uniform speed even when both sides of the central axis α in the X-axis direction (horizontal direction) are compared.

  In the advancing / retreating member 5 in the advanced position, the upper surface of the advancing / retreating member 5 is positioned at substantially the same height as the upper surface of the car side sill 42, so that, for example, the heel of a shoe, etc. Can be prevented.

  In the car 4, the abutting portion 7 is disposed at the end of the car door 41 (one abutting portion 7 is disposed at the end of the one car door 41 in the door opening direction, and the other abutting portion 7. Is arranged at the end of the other car door 41 in the door opening direction), the advance / retreat timing of the advance / retreat member 5 can be set to an appropriate timing in accordance with the opening / closing of the car door 41. Specifically, immediately after the car door 41 starts to open from the fully closed state, the advance / retreat member 5 in the retracted position can advance to the advanced position.
