In the above elevator, since a link mechanism configured by complicatedly combining a large number of parts is used to drive the closing member, failures and the like are likely to occur, and maintenance and the like are complicated.

Therefore, an object of the present invention is to provide an elevator capable of advancing and retreating a member capable of closing the gap between the car side sill and the landing side sill when the car lands with a simple configuration.

The elevator of the present invention
A landing with a landing side threshold extending in the width direction of the landing side entrance at the lower end of the landing side entrance,
A car door that opens and closes the car side doorway, a car side sill that extends in the same direction as the landing side sill at the lower end of the car side doorway and guides the car door, and the car side sill and the landing when landing. A basket with a gap closing mechanism, which closes the gap with the side sill,
The gap closing mechanism is
It has a shape that can close the gap between the car side sill and the landing side sill, and is between the advance position that closes the gap and the evacuation position that is separated from the landing side sill on the side of the car side sill. With the advancing / retreating member
It has a pressing portion capable of pressing the advancing / retreating member by opening / closing the car door.
The advancing / retreating member has a first contact portion capable of contacting the pressing portion when the car door opens and closes.
The pressing portion is a pair of first contact surfaces that can come into contact with the first contact portion when the car door opens and closes, and the advancing / retreating member of the pressing portion moves toward the door opening side in the opening / closing direction. It has a pair of first contact surfaces facing the retracted side in the advancing / retreating direction,
The pair of first contact surfaces are in a state where the first contact portion is in contact with at least one of the first contact surfaces of the pair of first contact surfaces when the car door is opened and closed. They are spaced apart from each other so that they can pass between them.

According to such a configuration, the advancing / retreating member moves in the advancing direction or retracts by opening and closing the car door in a state where the first contact portion is in contact with at least one of the first contact surfaces of the pair of first contact surfaces. With a simple configuration such as a first contact portion provided on the advancing / retreating member and a pair of first contact surfaces that come into contact with the first contact portion by opening and closing the car door in order to advance or retract by being pressed in the direction. , The advancing / retreating member capable of closing the gap between the car side sill and the landing side sill can be advanced / retreated.

In the elevator
The gap closing mechanism has an urging member that generates an urging force toward the retracting side in the advancing / retreating direction or increases the urging force as the advancing / retreating member advances from the retracting position to the advancing position.
When the car door opens and closes, the first contact portion contacts only one of the first contact surfaces of the pair of first contact surfaces.
The pressing portion is the first contact surface of one of the pair of first contact surfaces, which is the first contact surface that comes into contact with the first contact portion when the door is opened. It may have a second contact surface extending from the edge of the contact surface on the door closing side toward the advancing side in the advancing / retreating direction and in the door closing direction.

According to such a configuration, when the car door is opened and closed, the advancing / retreating member advances / retreats in a state where the advancing / retreating member is urged so that the first contact portion is pressed against the door opening side contact surface or the second contact surface. The advance / retreat operation of is stable.

Specifically, when the car door is opened from the fully closed position, the first contact portion moves along the door opening side contact surface in a state of being in contact with the door opening side contact surface (relative movement). ), The advancing / retreating member advances to the advancing position, and then the advancing / retreating member retracts by moving along the second contact surface with the first contact portion in contact with the second contact surface. Even if it is urged to the side, the position of the advancing / retreating member is maintained at the advancing position. On the other hand, when the car door is closed from the fully open position, the advancing / retreating member moves while the first contact portion is in contact with the second contact surface and moves along the second contact surface. The position of the advancing / retreating member is maintained at the advancing position even if it is urged to the retracting side, and then along the door opening side contact surface in a state where the first contact portion is in contact with the door opening side contact surface. The advancing / retreating member retracts by moving.

In addition, in the elevator,

According to such a configuration, the length dimension of the second contact surface in the opening / closing direction can be suppressed. That is, even if the length dimension of the second contact surface in the opening / closing direction is suppressed, the first contact portion is in contact with the second contact surface along the second contact surface when the door is opened. After moving toward the end on the door closing side, the second contact portion is in contact with the third contact surface (that is, the third contact surface) even if the distance from the end on the door closing side is separated. The position of the advancing / retreating member is maintained at the advancing position even if the advancing / retreating member is urged to the retracting side by moving along the third contact surface in the state of being in contact with the third contact surface.

In addition, in the elevator,
The advancing / retreating member has a first contact portion and a second contact portion arranged at a position different from the first contact portion.
The pressing portion has two pairs of contact surfaces and has two pairs of contact surfaces.
One pair of contact surfaces of these two pairs of contact surfaces is the pair of first contact surfaces arranged at positions corresponding to the first contact portion.
When the car door opens and closes, the first contact portion comes into contact with one of the pair of contact surfaces.
The other pair of contact surfaces of the two pairs of contact surfaces is such that when the car door opens and closes, the second contact portion is the other contact surface of the other pair of contact surfaces. They may be spaced apart from each other so that they can pass between them in contact with each other.

In this way, the two contact portions (first contact portion, second contact portion) of the advancing / retreating member face the opposite side of the pair of contact surfaces (that is, one pair of contacts). By abutting one of the contact surfaces and the other abutting surface of the other pair of abutting surfaces), the advancing / retreating member is sandwiched between the two abutting portions. Since the force in the direction or the force in the direction of being pushed out is applied, the rattling of the advancing / retreating member is suppressed and the advancing / retreating member can smoothly advance / retreat.

Further, the elevator of the present invention is
A car having a car side threshold extending in the width direction of the car side doorway at the lower end of the car side doorway.
A landing door that opens and closes the landing side entrance, a landing side sill that extends in the same direction as the car side sill at the lower end of the landing side entrance and guides the landing door, and the landing side sill when the car lands. And a landing having a gap closing mechanism for closing the gap between the car and the car side sill.
The gap closing mechanism is
It has a shape that can close the gap between the landing side sill and the car side sill, and is between the advance position that closes the gap and the evacuation position that is separated from the car side sill on the side of the landing side sill. With the advancing / retreating member
It has a pressing portion that can press the advancing / retreating member by opening / closing the landing door.
The advancing / retreating member has a contact portion that can come into contact with the pressing portion when the landing door opens and closes.
The pressing portion is a pair of contact surfaces that can come into contact with the contact portion when the landing door opens and closes, and as each of the pressing portions moves toward the door opening side in the opening / closing direction, the advancing / retreating member retracts in the advancing / retreating direction. Has a pair of side-facing contact surfaces
The pair of contact surfaces can pass between the pair of contact surfaces in a state where the contact portion is in contact with at least one of the contact surfaces of the pair of contact surfaces when the landing door is opened and closed. They are placed at intervals from each other.

According to this configuration, the landing door opens and closes with the contact portion in contact with at least one of the contact surfaces of the pair of contact surfaces, so that the advancing / retreating member is pushed in the advancing direction or the retracting direction to advance. Or, in order to evacuate, the gap between the landing side sill and the car side sill is created by a simple configuration such as a contact part provided on the advancing / retreating member and a pair of contact surfaces that come into contact with the contact part when the landing door opens and closes. The advancing / retreating member that can be closed can be advanced / retreated.

The parallel surface 5220B is a rectangular vertical surface extending from the edge of the orthogonal surface 5220A on the advancing side in the door closing direction and facing the retracted side. The parallel surface 5220B is arranged at a position where the advancing / retreating member 51 comes into contact with the first roller 5111 from the advancing side when the advancing / retreating member 51 is in the retracted position (for example, when the car door 43a is in the fully closed position).

The first contact surface 5220C is a rectangular vertical surface that extends from the edge of the parallel surface 5220B on the door closing side toward the advancing side toward the door closing direction and faces the retracting side. The first contact surface 5220C is the first contact surface of at least one of the pair of first contact surfaces 5210A and 5220C by the first roller 5111 when the car door 43a is opened and closed (in the example of the present embodiment). , The first contact surface 5210A of the first member 521) is arranged at a distance from the first contact surface 5210A of the first member 521 so that the first member 521 can pass between the first contact surface 5210A).

Specifically, the first contact surface 5220C of the present embodiment faces and is parallel to the first contact surface 5210A of the first member 521. The distance between the first contact surface 5210A of the first member 521 and the first contact surface 5220C of the second member 522 is larger than the diameter of the first roller 5111 (diameter when viewed from the Z-axis direction). That is, the first roller 5111 can contact only one of the first contact surfaces 5210A or 5220C when passing between the pair of first contact surfaces 5210A and 5220C.

In the gap closing mechanism 5 of the present embodiment, since the advancing / retreating member 51 is urged to the retracted side by the urging member 53, the first roller 5111 is in contact with the first contact surface 5210A of the first member 521. It passes between the pair of first contact surfaces 5210A and 5220C. That is, the first contact surface 5210A of the first member 521 hits the first roller 5111 when the first roller 5111 passes between the pair of first contact surfaces 5210A and 5220C when the car door 43 is opened and closed. It is placed in contact with it.

Further, at the end of the first contact surface 5220C of the second member 522 on the door closing side, the car door 43a is closed from the fully open position when the advancing / retreating member 51 is not urged by the urging member 53. As a result, the pressing portion 52a extends to a position where it can come into contact with the first roller 5111 when it moves with respect to the first roller 5111 in the door closing direction (see FIG. 9).

The third member 523 is connected to the third guide wall 5231 having the third guide surface 5230 perpendicular to the horizontal plane, the third guide wall 5231, and the first member 521 and the second member 522 are connected to each other. It has a connecting portion 5232 and. The third guide wall 5231 of the present embodiment is a plate-shaped portion, and is bent at a plurality of locations. The third connecting portion 5232 is a plate-shaped portion extending in the horizontal direction at the upper end of the third guide wall 5231. In the pressing portion 52a of the present embodiment, the first connecting portion 5212 of the first member 521 and the second connecting portion 5222 of the second member 522 are connected to the third connecting portion 5232 of the third member 523 by the fastening member B such as a bolt. It is fixed (connected) (see FIG. 6).

The third guide surface 5230 is arranged below the first guide surface 5210 and the second guide surface 5220 in the Z-axis direction. The third guide surface 5230 includes a plurality of planes 5230A, 5230B, and 5230C divided at the bent portion of the third guide wall 5231, and each plane is a vertical plane. Specifically, the third guide surface 5230 of the present embodiment has a second inclined surface 5230A extending in a direction inclined with respect to the X-axis direction, a third contact surface 5230B extending in the X-axis direction, and the third contact surface 5230B extending in the X-axis direction. It includes a third inclined surface 5230C extending in an inclined direction with respect to the third inclined surface.

The second inclined surface 5230A is a rectangular vertical surface that extends in the direction toward the retracting side and faces the advancing side as the door opens.

The third contact surface 5230B is a rectangular vertical surface extending in the door closing direction from the edge of the second inclined surface 5230A on the door closing side and facing the advancing side. In the third contact surface 5230B, the car door 43a moves in the door opening direction with the first roller 5111 in contact with the second contact surface 5210B, whereby the first roller 5111 moves to the second contact surface. The second roller 5121 is arranged at a position where it comes into contact with the door opening side end of the third contact surface 5230B (see FIG. 10) when it moves to the door closing side end of the 5210B. That is, the second roller 5121 comes into contact with the end of the third contact surface 5230B on the door opening side when the first roller 5111 is in contact with the end of the second contact surface 5210B on the door closing side. It is placed in position. The length dimension of the third contact surface 5230B (the dimension in the moving direction of the second roller 5121 when the second roller 5121 moves along the third contact surface 5230B) reaches the fully open position of the car door 43a. This is the size that the second roller 5121 is in contact with when the door is opened (that is, when the door opening operation is completed).

The third inclined surface 5230C is a vertical surface extending from the edge of the third contact surface 5230B on the door closing side toward the retracting side and facing the advancing side toward the door closing direction.

In the elevator 1 configured as described above, when the car door 43 and the landing door 32 are interlocked to open and close in a state where the car 4 is stopped (landed) at the landing 3 on a predetermined floor, the car door 43 The advancing / retreating member 51 of the gap closing mechanism 5 advances / retreats by utilizing the opening / closing operation. The details are as follows.

First, in order to close the gap between the car side sill 44 and the landing side sill 33, the operation of each configuration of the elevator 1 when the advancing / retreating member 51 advances will be described with reference to FIGS. 7 to 11. In each of the drawings of FIGS. 7 to 11, FIG. 7A shows the positional relationship between the first roller 5111 and the first guide surface 5210, and FIG. 7B shows the position at the same timing as FIG. The positional relationship between the two rollers 5121 and the second guide surface 5220 is shown.

The landing door 32 opens and closes in conjunction with (following) the opening and closing of the car door 43. Therefore, in the following description, only the opening and closing of the car door 43 will be described. Further, the operation of the car door 43a on one side, the operation of each part on one side of the center line C of the gap closing mechanism 5, the operation of the car door 43b on the other side, and the center line C of the gap closing mechanism 5. Since the operation of each part on the other side is symmetrical with respect to the center line C, in the following description, from the operation of the car door 43a on one side and the center line C of the gap closing mechanism 5. The operation of each part on one side will be described.

When the car door 43a is in the fully closed position, the first roller 5111 of the advancing / retreating member 51 is in contact with the parallel surface 5220B of the second member 522 of the pressing portion 52a, and is separated from the orthogonal surface 5220A in the X-axis direction. Yes, the second roller 5121 is separated from the third guide surface 5230 of the pressing portion 52 (see FIG. 7). In this state, the advancing / retreating member 51 is in the retracted position by at least one of the urging force by the urging member 53 and the restriction (prevention) of the movement of the first roller 5111 in the advancing direction by the parallel surface 5220B of the second member 522. Is maintained at.

Next, when the car door 43a moves in the door opening direction with the car 4 landing on the landing 3, the first roller 5111 is separated from the parallel surface 5220B of the second member 522, and the first member 521 is the first. It abuts on one contact surface 5210A (specifically, the end of the first contact surface 5210A on the door opening side). In this state, the second roller 5121 is in a position where it has not yet reached (contacted) the third guide surface 5230 (see FIG. 8).

Further squirrel door 43a from this state continues to move in the door-opening direction, the first roller 5111 is pressed by the first contact surface 5210A, the rotation axis C ₁ around in a state where the first has abutment surfaces 5210A abuts It moves toward the door closing direction with respect to the first contact surface 5210A while rotating to. At this time, since the distance between the pair of first contact surfaces 5210A and 5220C is larger than the diameter of the first roller 5111, the first roller 5111 comes into contact with the first contact surface 5210A of the first member 521. The two members 522 pass between the pair of first contact surfaces 5210A and 5220C without contacting (contacting) the first contact surfaces 5220C.

As the first roller 5111 moves with respect to the first contact surface 5210A, the advancing / retreating member main body 510 to which the first roller 5111 is attached advances from the retracted position, and the first roller 5111 moves to the first contact surface 5210A. When the edge on the door closing side (the boundary position with the second contact surface 5210B) is reached, the advancing / retreating member main body 510 reaches the advancing position. As a result, the gap g between the car side sill 44 and the landing side sill 33 is closed by the advancing / retreating member main body 510, and when a passenger gets on and off the car 4, an object (such as a key) from this gap g into the hoistway 2. It is possible to prevent the fall of passengers' belongings, etc.).

When the advancing / retreating member main body 510 is advanced, the advancing / retreating member main body 510 is constantly subjected to the urging force toward the retracted side by the urging member 53, so that the first roller 5111 comes into contact with the first member 521. It is always pressed against the surface 5210A. Therefore, the first roller 5111 moves to the door closed side with respect to the first contact surface 5210A in a state of being in constant contact with the first contact surface 5210A which is a smooth flat surface. As a result, the advancing / retreating member main body 510 smoothly advances from the retracted position to the advanced position at a speed corresponding to the inclination of the first contact surface 5210A with respect to the opening / closing direction (X-axis direction).

Further, when the movement of the car door 43a in the door opening direction continues, the first roller 5111 moves from the first contact surface 5210A to the second contact surface 5210B (see FIG. 9), and the second contact surface 5210B. moves in the door-closing direction relative to the second contact surface 5210B while rotating the rotary shaft C ₁ around in contact with the. At this time as well, the advancing / retreating member main body 510 is subjected to the urging force toward the retracting side by the urging member 53, but the second contact surface 5210B prevents the first roller 5111 from moving to the retracting side (regulation). ), Therefore, the position of the advancing / retreating member main body 510 in the advancing / retreating direction (Y-axis direction) is maintained at the advancing position.

When the car door 43a moves in the door opening direction until the first roller 5111 has moved to the end of the second contact surface 5210B on the door closing side, the second roller 5121 moves to the third member 523 of the third member 523. It comes into contact with the contact surface 5230B (see FIG. 10). Subsequently, the first roller 5111 separates from the second contact surface 5210B (first guide surface 5210), while the second roller 5121 continues to contact the third contact surface 5230B. That is, the second roller 5121 moves to the door-closing direction relative to the third abutment surface 5230B while rotating the rotary shaft C ₂ about a third abutment surface 5230B and state abutting. At this time, the second contact surface 5210B eliminates the prevention (regulation) of the movement of the first roller 5111 to the retracting side, but the third contact surface 5230B prevents the second roller 5121 from moving to the retracting side. Therefore, the position of the advancing / retreating member main body 510 to which the second roller 5121 is attached in the advancing / retreating direction continues to be maintained at the advancing position.

The contact of the second roller 5121 with the third contact surface 5230B continues until the car door 43a reaches the fully open position, and in the gap closing mechanism 5 of the present embodiment, when the car door 43a is in the fully open position, the second roller 5121 is in contact with the third contact surface 5230B. The two rollers 5121 are in contact with the end of the third contact surface 5230B on the door closing side (see FIG. 11).

As described above, in the elevator 1 of the present embodiment, when the car door 43 is opened, the gap closing mechanism 5 advances and retreats by utilizing the opening / closing force (force moving in the door opening direction) of the car door 43. The member 51 is advanced to close the gap g between the car side sill 44 and the landing side sill 33. On the other hand, the operation of each configuration of the elevator 1 when the advance / retreat member 51 is retracted in order for the car 4 to move (elevate) from the landing 3 is the operation of each configuration of the elevator 1 when the advance / retreat member 51 advances. The opposite is true.

According to the elevator 1 of the present embodiment, the first contact surface with at least one of the pair of first contact surfaces 5210A and 5220C (the first contact surface 5210A in the example of the present embodiment). When the car door 43 opens with the portion 511 in contact with the portion 511, the advancing / retreating member 51 is pressed and advances (moves to the advance side). Therefore, the first contact portion 511 provided on the advancing / retreating member 51 and the pair of first contact surfaces 5210A and 5220C that come into contact with the first contact portion 511 when the car door 43 is opened are provided. , The advancing / retreating member 51 capable of closing the gap g between the car side sill 44 and the landing side sill 33 can be advanced.

In the gap closing mechanism 5 of the present embodiment, the urging member 53 is provided, and when the advancing / retreating member 51 is located at least on the advance side from the retracted position, the urging member 53 always urges the retracted side. Has been done. Therefore, in the gap closing mechanism 5, the first contact portion 511 (first roller 5111) advances and retreats in a state of being in constant contact with the first guide surface 5210 (first contact surface 5210A). However, in the gap closing mechanism 5 of the present embodiment, when the urging force of the urging member 53 is no longer applied to the advancing / retreating member 51 due to damage of the urging member 53 or the like, the car door 43 opens from the fully closed position. Occasionally, the first contact portion 511 (first roller 5111) is pressed by the first contact surface 5210A of the first member 521, so that the advance / retreat member 51 advances from the retracted position, and the car door 43 opens from the fully open position. When closing, the first contact portion 511 (first roller 5111) is pressed by the first contact surface 5220C of the second member 522, so that the advance / retreat member 51 retracts from the advance position. As described above, in the gap closing mechanism 5 of the present embodiment, the advancing / retreating member 51 can be advanced / retracted by opening / closing the car door 43 regardless of the presence / absence of the urging member 53.

Further, in the elevator 1 of the present embodiment, the gap closing mechanism 5 has an urging member 53 that urges the advancing / retreating member 51 to the retracted side. Therefore, when the car door 43 opens and closes, the first contact portion 511 causes the first guide surface 5210 of the first member 521 (first contact surface (door opening side contact surface) 5210A, second contact surface 5210B). Since the advancing / retreating member 51 advances / retreats in a state of being urged so as to be pressed against the (including), the advancing / retreating operation of the advancing / retreating member 51 is stable.

Specifically, when the car door 43 is opened from the fully closed position, the first roller 5111 is in contact with the first contact surface 5210A of the first member 521 (due to the urging force of the urging member 53). It moves (relatively moves) along the first contact surface 5210A in a state of being pressed by the force of force), whereby the advancing / retreating member 51 smoothly advances according to the shape of the first contact surface 5210A. After that, the first roller 5111 moves along the second contact surface 5210B in a state of being in contact with the second contact surface 5210B, so that the advance / retreat member 51 is urged to the retracting side, so that the advance / retreat member The position of 51 is stably maintained at the advance position.

On the other hand, when the car door 43 is closed from the fully open position, the first roller 5111 advances and retreats while moving along the second contact surface 5210B in a state of being in contact with the second contact surface 5210B. Since the member 51 is urged to the retracted side, the position of the advancing / retreating member 51 is stably maintained at the advancing position. After that, the first roller 5111 moves along the first contact surface 5210A in a state where the first roller 5111 is in contact with the first contact surface 5210A, so that the advancing / retreating member 51 is smoothed according to the shape of the first contact surface 5210A. Evacuate to.

Further, in the elevator 1 of the present embodiment, the pressing portion 52 has a third contact surface 5230B, and the advancing / retreating member 51 has a second contact portion 512 (second roller 5121). Therefore, in the gap closing mechanism 5 of the present embodiment, the length dimension of the second contact surface 5210B (the first contact portion when the first contact portion 511 moves along the second contact surface 5210B). The dimension in the moving direction of 511) can be suppressed. That is, even if the length dimension of the second contact surface 5210B is suppressed, the first contact portion 511 is in contact with the second contact surface 5210B along the second contact surface 5210B when the door is opened. The second contact portion 512 is in contact with the third contact surface 5230B (that is, in contact with the third contact surface 5230B) even if the second contact portion 512 is separated from the second contact surface 5210B. By moving along the third contact surface 5230B), the position of the advancing / retreating member 51 is maintained at the advancing position even if the advancing / retreating member 51 is urged to the retracted side.

In the elevator 1 configured as described above, when the car door 43 and the landing door 32 are interlocked to open and close in a state where the car 4 is stopped (landed) at the landing 3 on a predetermined floor, the car door 43 The advancing / retreating member 51 of the gap closing mechanism 5A advances / retreats by utilizing the opening / closing operation. The details are as follows.

First, in order to close the gap between the car side sill 44 and the landing side sill 33, the operation of each configuration of the elevator 1 when the advancing / retreating member 51 advances will be described with reference to FIGS. 16 to 18. In each of FIGS. 16 to 18, FIG. (a) shows the positional relationship between the first roller 5111 and the fifth guide surface 5250 of the fifth member 525 and the sixth guide surface 5260 of the sixth member 526. FIG. (B) shows the positional relationship between the second roller 5121 and the seventh guide surface 5270 of the seventh member 527 and the eighth guide surface 5280 of the eighth member 528 at the same timing as in FIG.

When the car door 43 is in the fully closed position, the first roller 5111 of the advancing / retreating member 51 is in contact with the parallel surface 5260B of the sixth member 526 of the pressing portion 52A, and is separated from the orthogonal surface 5260A in the X-axis direction. The second roller 5121 is in contact with the parallel surface 5280B of the eighth member 528 and is separated from the orthogonal surface 5280A in the X-axis direction (see FIG. 16). In this state, the advancing / retreating member 51 is restricted by the urging force of the urging member 53, the movement of the first roller 5111 in the advancing direction by the parallel surface 5260B of the sixth member 526, and the parallel surface of the eighth member 528. It is maintained in the retracted position by at least one of the restrictions (blocking) of the movement of the second roller 5121 in the advancing direction by the 5280B.

Next, when the car door 43 moves in the door opening direction with the car 4 landing on the landing 3, the second roller 5121 is separated from the parallel surface 5280B of the eighth member 528, and the seventh member 527 is separated from the parallel surface 5280B. It comes into contact with one contact surface 5270A (specifically, the end of the first contact surface 5270A on the door opening side). At this time, the first roller 5111 moves from the parallel surface 5260B to the first contact surface 5260C while continuing to abut on the sixth guide surface 5260 of the sixth member 526 (see FIG. 17).

When the car door 43 continues to move in the door opening direction from this state, the second roller 5121 is pressed by the first contact surface 5270A of the seventh member 527, and is in contact with the first contact surface 5270A. moves in the door-closing direction relative to the first abutment surface 5270A while rotating the rotary shaft C ₂ around. The first roller 5111 is moved in the door-closing direction relative to the first abutment surface 5260C while rotating the rotary shaft _{C 1} around the first contact surface 5260C and state contact with the sixth member 526.

At this time, the first roller 5111 comes into contact with the first contact surface 5260C in a state of having a force component for pressing the first contact surface 5260C from the normal direction, and the second roller 5121 abuts in the normal direction. Is in contact with the first contact surface 5270A in a state having a component of a force for pressing the first contact surface 5270A. As a result, when the car door 43 is opened and closed, the first and second rollers 5111 and 5121 move between the pair of upper first contact surfaces 5250A and 5260C and the pair of lower first contact surfaces 5270A and 5280C. While passing through (that is, while the advancing / retreating member 51 is moving in the advancing / retreating direction), the pressing portion 52A is sandwiched between two rollers (first roller 5111 and second roller 5121) when viewed from the Z-axis direction. It is in a state.

In the advancing / retreating member 51 of the present embodiment, the first contact portion 511 (first roller 5111) and the second contact portion 512 (second roller 5121) are provided only on one end in the longitudinal direction (X-axis direction). Since the car door 43 is provided, the pressing force from the pressing portion 52A is applied only to the one end portion of the advancing / retreating member 51 when the car door 43 is opened / closed, but the advancing / retreating member 51 is smooth without rattling due to the above pinching. You can move in and out.

The movement of the sixth member 526 of the first roller 5111 with respect to the first contact surface 5260C in a state of being in contact with the first contact surface 5260C as described above, and the first contact of the seventh member 527 of the second roller 5121. With the movement of the first contact surface 5270A in contact with the contact surface 5270A, the advancing / retreating member main body 510 to which the first roller 5111 and the second roller 5121 are attached advances from the retracted position. Then, the first roller 5111 reaches the end of the sixth member 526 on the door-closing side of the first contact surface 5260C, and the second roller 5121 reaches the end of the seventh member 527 on the door-closing side of the first contact surface 5270A. At the timing of reaching (the boundary position between the first contact surface 5270A and the second contact surface 5270B), the advance / retreat member main body 510 reaches the advance position. As a result, the gap g between the car side sill 44 and the landing side sill 33 is closed by the advancing / retreating member main body 510, and when a passenger gets on and off the car 4, an object (such as a key) from this gap g into the hoistway 2. It is possible to prevent the fall of passengers' belongings, etc.).

Further, when the movement of the car door 43 in the door opening direction continues, the first roller 5111 separates from the first contact surface 5260C of the sixth member 526 and then reaches the second contact surface 5250B of the fifth member 525. contact moves in the door-closing direction relative to the second contact surface 5250B while rotating the rotary shaft C ₁ around in contact with the said second contact surface 5250B. On the other hand, the second roller 5121 moves from the first contact surface 5270A to the second contact surface 5270B on the seventh guide surface 5270 of the seventh member 527, and rotates in a state of being in contact with the second contact surface 5270B. moves in the door-closing direction relative to the second contact surface 5270B while rotating axis C ₂ around. At this time, the urging member 53 always applies an urging force to the advancing / retreating member main body 510 in the retracting direction, but the second contact surface 5250B of the fifth member 525 prevents the first roller 5111 from moving to the retracting side ( In addition to being regulated), the second contact surface 5270B of the seventh member 527 prevents (regulates) the movement of the second roller 5121 to the retracted side, so that the advancing / retreating member main body 510 is in the Y-axis direction (advancing / retreating direction). The position is maintained at the advance position.

The contact of the first roller 5111 with the second contact surface 5250B of the fifth member 525 and the contact of the second roller 5121 with the second contact surface 5270B of the seventh member 527 are caused by the car door 43. It continues until it reaches the fully open position, and in the gap closing mechanism 5A of the present embodiment, when the car door 43 is in the fully open position, the first roller 5111 comes into contact with the end of the second contact surface 5250B on the door closing side, and at the same time, The second roller 5121 comes into contact with the end of the second contact surface 5270B on the door closing side (see FIG. 18).

As described above, in the elevator 1 of the present embodiment, when the car door 43 is opened, the gap closing mechanism 5A advances and retreats by utilizing the opening / closing force (force moving in the door opening direction) of the car door 43. The member 51 is advanced to close the gap between the car side sill 44 and the landing side sill 33. On the other hand, the operation of each configuration of the elevator 1 when the advance / retreat member 51 is retracted in order for the car 4 to move (elevate) from the landing 3 is the operation of each configuration of the elevator 1 when the advance / retreat member 51 advances. The opposite is true.

According to the elevator 1 of the present embodiment, the first contact portion 511 (first roller 5111) is attached to the first contact surface 5260C of one of the pair of first contact surfaces 5250A and 5260C on the upper side of the pressing portion 52A. ) Is in contact with the first contact surface 5270A of the pair of first contact surfaces 5270A and 5280C on the lower side of the pressing portion 52A, and the second contact portion 512 (second roller 5121) is in contact with the first contact surface 5270A. When the car door 43 opens and closes in contact with the car door 43, the advancing / retreating member 51 is pressed to advance / retreat. Therefore, the pair of first contact surfaces 5250A and 5260C that come into contact with the first contact portion 511 by opening and closing the first contact portion 511, the second contact portion 512, and the car door 43 provided on the advancing / retreating member 51. The gap between the car side sill 44 and the landing side sill 33 is closed by a simple configuration such as a pair of first contact surfaces 5270A and 5280C that come into contact with the second contact portion 512 by opening and closing the car door 43. The possible advance / retreat member 51 can be advanced / retreated.

May be good.

Further, in the elevator 1 of the above embodiment, the first contact surfaces 5210A, 5220C, 5250A, 5260C, 5270A, and 5280C of the pressing portions 52 and 52A are straight surfaces when viewed from the Z-axis direction. Not limited to. Each of the first contact surfaces 5210A, 5220C, 5250A, 5260C, 5270A, 5280C may be a surface that is curved or bent when viewed from the Z-axis direction.

In the elevator 1 of the first embodiment, the gap closing mechanism 5 extends in parallel with the two contact portions (first contact portion 511 and second contact portion 512) and corresponds to the contact portion. The unit has two contact surfaces (second contact surface 5210B and third contact surface 5230B) that come into contact with the portion from the retracted side, but the configuration is not limited to this. The gap closing mechanism 5 includes three or more contact portions and three or more contact surfaces corresponding to each of the three or more contact portions (extending in the X-axis direction and retracting to the corresponding contact portions). A vertical surface that comes into contact with the surface) and may have. In this case, while the car door 43 is performing the door opening operation or the door closing operation with the advancing / retreating member main body 510 positioned at the advanced position, at least one of the three or more contact surfaces is in contact with the contact surface. Each of the three or more contact surfaces is arranged so as to contact the contact portion (corresponding contact portion) from the retracted side. For example, specifically, when the car door 43 and the landing door 32 are opened or closed, the second hit is performed at the timing when the contact portion corresponding to the contact surface is separated from the first contact surface. The contact portion corresponding to the contact surface comes into contact with the contact surface, and then corresponds to the third contact surface at the timing when the contact portion corresponding to the contact surface separates from the second contact surface. The contact portion corresponding to the contact surface comes into contact, and then the contact surface corresponds to the fourth contact surface at the timing when the contact portion corresponding to the contact surface separates from the third contact surface. The contact portion is in contact with the contact portion, and the operation of ... is repeated. With such a configuration, the dimensions of each contact surface (each surface extending in the X-axis direction and contacting the corresponding contact portion from the retracting side) in the X-axis direction (opening / closing direction) can be suppressed. The dimensions of the pressing portion 52 in the X-axis direction can be suppressed. It should be noted that this configuration (a configuration in which the pressing portion 52A extends in parallel in the X-axis direction and has two or more contact surfaces that abut on the corresponding contact portion from the retracted side) is similar to the elevator 1 of the second embodiment. It can also be used in the gap closing mechanism 5A arranged in the side-open type (single-open type) car door 43 or the landing door 32.

Further, in the elevator 1 of the first and second embodiments, the urging member 53 urges the advancing / retreating member 51 to the retracting side, but the configuration is not limited to this. The urging member 53 may be configured to urge the advancing / retreating member 51 toward the advancing side. In this case, in the gap closing mechanism 5 of the first embodiment, when the first contact portion 511 (first roller 5111) passes between the pair of first contact surfaces 5210A and 5220C, it is different from that of the first embodiment. Abuts on the opposite first contact surface 5220C. The second contact surface for maintaining the position of the advancing / retreating member 51 that has advanced to the advanced position extends in the door closing direction from the edge of the opposite first contact surface 5220C on the door closing side and is on the retracting side. It is a vertical surface facing (the side opposite to the second contact surface 5210B of the first embodiment), and the third contact surface with which the second contact portion 512 (second roller 5121) contacts is in the X-axis direction. It is a vertical plane that extends parallel to and faces the retracted side (the side opposite to the third contact surface 5230B of the first embodiment).

In the elevator 1 of the second embodiment, when the advancing / retreating member 51 is advancing or retracting, the first roller 5111 is first hit between the pair of upper first contact surfaces 5210A and 5220C from the normal direction. The second roller 5121 comes into contact with the first contact surface 5260C in a state of having a force component for pressing the contact surface 5260C, and the second roller 5121 is normal between the pair of lower first contact surfaces 5270A and 5280C. The first contact surface 5270A is in contact with the first contact surface 5270A in a state of having a component of a force for pressing the first contact surface 5270A, but the present invention is not limited to this configuration.

For example, when the advancing / retreating member 51 is advancing or retracting, the force by which the first roller 5111 presses the first contact surface 5250A from the normal direction between the pair of upper first contact surfaces 5210A and 5220C. The second roller 5121 abuts on the first contact surface 5250A with the component of the above, and the second roller 5121 is located between the pair of lower first contact surfaces 5270A and 5280C from the normal direction to the first contact surface 5280C. The first contact surface 5280C may be brought into contact with the first contact surface 5280C in a state having a component of a force for pressing. In the case of this configuration, when the car door 43 is opened and closed, the first and second rollers 5111, between the pair of upper first contact surfaces 5250A and 5260C and the lower pair of first contact surfaces 5270A and 5280C, While the 5121 is passing (that is, while the advancing / retreating member 51 is moving in the advancing / retreating direction), these two rollers (first roller 5111 and second roller 5121) face each other when viewed from the Z-axis direction. The two first contact surfaces (upper first contact surface 5250A and lower first contact surface 5280C) facing the surface are pushed apart. Therefore, even with such a configuration, the first contact portion 511 (first roller 5111) and the second contact portion 512 (second roller 5121) are provided only on one end in the longitudinal direction (X-axis direction). The advancing / retreating member 51 can advance / retreat smoothly without rattling.
