A sill of an elevator door according to embodiment 1 will be described. Fig. 1 is a front view showing a part of an elevator in which a sill of an elevator door of embodiment 1 is provided. Fig. 2 is a side view showing a part of an elevator in which a sill of an elevator door according to embodiment 1 is provided.
As shown in fig. 1 and 2, a car 1 that moves up and down in a hoistway in response to an operation of an elevator has a rectangular parallelepiped shape, and an upper beam 2, a lower beam 3, and a pair of left and right columns 4 that support the car 1 are provided around the car 1. A rope 5 for suspending the car 1 is fixed to the upper beam 2. The rope 5 can be wound up by a hoisting machine (not shown). That is, the hoisting machine winds the rope 5 to raise and lower the car 1 in the vertical direction.
The other end of the rope 5 fixed to the car 1 is fixed to the counterweight 6. The counterweight 6 is suspended by the ropes 5 via a hoisting machine and a sheave, and is disposed on the rear surface of the car 1. The counterweight 6 is lifted and lowered in a direction opposite to the lifting and lowering operation of the car 1.
Fig. 3 is a diagram showing the car door apparatus 8. A car door device 8 for opening and closing the car door 7 when a user moves on and off is provided on the landing side of the car 1. As shown in fig. 5, a landing door device 10 for opening and closing the landing door 9 when a user moves on and off is provided on the hoistway side of the landing. In the present embodiment, the elevator door refers to a door including a car door 7 and a landing door 9. The elevator door sill 100 guides opening and closing of a door apparatus provided in an elevator, and includes a car door 7 sill and a landing door 9 sill.
Fig. 3 is a view showing the vicinity of the car door when the car door device 8 is viewed from the landing side. The car door apparatus 8 of fig. 3 includes two car doors 7. The car doors 7 are double doors in which the car doors 7 are opened and closed in the left and right directions, respectively.
As shown in fig. 3, the upper portion of the car door 7 is connected to the hanger plate 11A. A hanger plate 11A is provided with hanger rollers 12A. The hanger roller 12A is provided to the hanger housing 13A. The hanger housing 13A includes a door rail 14A, and the hanger roller 12A can move laterally along the door rail 14A.
A car sill 15 constituting a sill 100 of an elevator door is provided at a lower portion of the car door apparatus 8. The car sill 15 guides opening and closing of the car door 7 of the car door apparatus 8. The car sill 15 is composed of a car sill main body portion 16 and a car sill guide portion 17. The car sill main body 16 may be manufactured by cutting or extrusion molding a metal block material, for example, or may be manufactured by another known method.
The car sill main body 16 constitutes a main body of the sill 100 of the elevator door. The car sill main portion 16 extends in the opening and closing direction of the car door apparatus 8. A door shoe 19 as a sliding member is provided at a lower portion of the car door device 8, and the door shoe 19 slides on the car sill main body portion 16 when the car door 7 is opened and closed. The door shoe 19 is provided at the lower end of the car door apparatus 8, for example. The car sill main portion 16 includes a groove 20 for guiding opening and closing of the car door apparatus 8 by sliding the door shoe 19. The sliding direction of the car door 7 can be said to be determined by the movement of the door shoe 19 along the groove 20 of the car sill body 16. A baffle 21 for preventing falling is provided at the landing side lower end portion of the car 1.
The car sill guide 17 constitutes a guide of the sill 100 of the elevator door. The car sill guide 17 is provided at both ends of the car sill main 16. The car sill guide 17 may be provided at least one end of the car sill main 16.
The car sill guide 17 extends in a direction away from the car door apparatus 8 over the opening/closing stroke of the car door apparatus 8. The sliding direction of the car door 7 is determined by the car sill guide 17. The car sill guide 17 slides the door shoes 19 to guide the opening and closing of the car door apparatus 8.
As in the case where the car door 7 is guided by the car sill main body portion 16 when opening and closing, the car door 7 is guided by the car sill guide portion 17 when opening and closing. In addition, in the case where the car door 7 is one piece, that is, in the case where the car door 7 is a single-open car door apparatus 8, the car sill guide 17 is provided at one end of the car sill 15. The structure of the car door 7 is not limited to this, and may be a structure having two or more car doors 7 on the left and right sides, and the same is true in other embodiments.
Fig. 4 is a cross-sectional view at A-A of fig. 3. As shown in fig. 4, the car sill guide 17 is constituted by a car sill guide 17A. The car sill guide 17 at one end of the car sill 15 is composed of two car sill guides 17A. When the car sill 15 is viewed in the vertical direction, the cross section of the car sill guide 17A is L-shaped.
The car sill main 16 is constituted by a car sill main 16A. The car sill guide 17A includes a fixing portion fixed to the car sill main body 16A and a guide portion for guiding the car door 7. The guide portion extends from the fixing portion in a direction away from the car door 7 along the opening and closing direction of the car door device 8. The car sill guide 17A is fixed to the car sill main body 16A by fastening a fixing portion to the car sill main body 16 with a bolt B (omitted in the following drawings). The car sill guide 17A may be provided with a fixing portion fixed to the car sill main body 16A and a guide portion for guiding the car door 7, and the cross-sectional shape may be other than an L-shape. The method of fixing the car sill guide 17A to the car sill main body 16A is not particularly limited as long as it is not a method of interfering with the guidance of the car door 7 when the car door 7 is opened and closed.
The car sill guide 17A can be manufactured by bending a metal plate, for example. Thus, the fixing portion and the guide portion of the car sill guide 17A can be constituted by one member. The car sill guide 17A is preferably formed by bending a metal plate, because it has an L-shaped cross section. The car sill guide 17A is provided with two pieces so as to sandwich the door shoe 19 in the front-rear direction. The car sill guide 17A is provided at both ends of the car sill main body 16A, respectively.
As shown in fig. 4, the car sill guide 17 is configured to form an air passage in the vertical direction of the hoistway when the car sill 15 is viewed in the vertical direction. That is, the car sill guide 17 is configured such that the sum of the cross-sectional areas of the car sill main body 16 and the car sill guide 17 when the car sill 15 is viewed from the vertical direction is smaller than the cross-sectional area of the car sill main body 16 when the car sill 15 is viewed from the vertical direction when the car sill main body 16 is extended to the end of the car sill guide 17.
By configuring the car sill guide 17 in this way, the flow area of air around the car sill guide 17 is enlarged. When the elevator is operated, the car sill 15 approaches the landing sill 22, and noise is generated due to air turbulence, but by providing the car sill guide 17 of the present embodiment, the flow area of air around the car sill guide 17 is enlarged, and thus noise caused by air turbulence when the car sill 15 approaches the landing sill 22 can be reduced. As a result, the silence in the car 1 can be improved.
The entire length of the car sill main body 16 extends over a wide lateral range of the car door 7. This can realize the function of supporting the riding and descending of the user, and can reduce the material used by setting the entire length to the lateral width of the car door 7, and can facilitate the production, thereby reducing the production cost. The entire length of the car sill main body 16 may extend over a substantially wide lateral range of the car door 7, and is not necessarily strictly equal to the wide lateral range of the car door apparatus 8.
Next, the sill of the landing door 9 will be described with reference to fig. 5 and 6. Fig. 5 is a view showing the periphery of the landing door when the landing door apparatus 10 is viewed from the landing side. As shown in fig. 5, the upper portion of the landing door 9 is connected to a hanger plate 11B. A hanger plate 11B is provided with hanger rollers 12B. The hanger roller 12B is provided to the hanger housing 13B. The hanger housing 13B includes a door rail 14B, and the hanger roller 12B can move laterally along the door rail 14B.
A landing sill 22 constituting a sill 100 of an elevator door is provided at a lower portion of the landing door apparatus 10. The landing sill 22 guides the opening and closing of the landing door 9 of the landing door apparatus 10. The landing sill 22 is composed of a landing sill main body 23 and a landing sill guide 24. The landing sill main body 23 may be manufactured by cutting or extrusion molding a metal block material, for example, or may be manufactured by another known method.
The landing sill main portion 23 extends along the opening and closing direction of the landing door apparatus 10. A door shoe 19 as a sliding member is provided at a lower portion of the landing door device 10, and the door shoe 19 slides on the landing sill main portion 23 when the landing door 9 is opened and closed. The door shoe 19 is provided at the lower end of the landing door apparatus 10, for example. The landing sill main body 23 includes a groove 20 for guiding the opening and closing of the landing door device 10 by sliding the door shoe 19. It can be said that the sliding direction of the landing door 9 is determined by the movement of the door shoe 19 along the groove 20 of the landing sill body 23.
The entire length of the landing sill main portion 23 extends over a substantially wide lateral range of the landing door 9. This can realize the function of supporting the user's riding and descending, and can facilitate the production by setting the overall length to the extent of the lateral width of the landing door 9, and can reduce the material used, thereby enabling the production cost to be reduced.
The landing sill guide 24 constitutes a guide of the sill of the elevator door. The landing sill guide 24 is provided at both ends of the landing sill main 23. The landing sill guide 24 may be provided at least one end of the landing sill main 23.
The landing sill guide 24 extends in a horizontal direction away from the landing door apparatus 10 over the opening/closing stroke of the landing door apparatus 10. The sliding direction of the landing door 9 is determined by the landing sill guide 24. The landing sill guide 24 slides the door shoes 19 to guide the opening and closing of the landing door apparatus 10.
The landing door 9 is guided by the landing sill guide 24 when opening and closing, as in the case where the car door 7 is guided by the car sill main body 16 when opening and closing. In addition, in the case where the landing door 9 is one piece, that is, in the case where the landing door 9 is a single-open landing door apparatus 10, the landing sill guide 24 is provided at one end of the landing sill 22. The structure of the landing door 9 is not limited to this, and may be a structure having two or more landing doors 9 on the left and right sides, and the same is true in other embodiments.
Fig. 6 is a cross-sectional view at A-A of fig. 5. As shown in fig. 6, the landing sill guide 24 is constituted by a landing sill guide 24A. The landing sill guide 24 of one end of the landing sill 22 is constituted by two landing sill guides 24A. When the landing sill 22 is viewed in the vertical direction, the landing sill guide 24A has an L-shaped cross section.
As in the case where the landing door 9 is guided by the landing sill main body 23 when opening and closing, the landing door 9 is guided by the landing sill guide 24A when opening and closing. In addition, in the case where the landing door 9 is one piece, that is, in the case where the landing door 9 is the single-open landing door apparatus 10, the landing sill guide 24A is provided at one end of the landing sill 22. The structure of the landing door 9 is not limited to this, and may be a structure having two or more landing doors 9 on the left and right sides, and the same is true in other embodiments.
The landing sill body 23 is composed of a landing sill body 23A. The landing sill guide 24A includes a fixing portion fixed to the landing sill main body 23A and a guide portion guiding the landing door 9. The guide portion extends from the fixing portion in a direction away from the landing door 9 along the opening and closing direction of the landing door apparatus 10. The landing sill guide 24A is fixed to the landing sill body 23A by fastening the fixing portion to the landing sill body 23A with, for example, a bolt (not shown). The landing sill guide 24A may be provided with a fixing portion fixed to the landing sill main body 23A and a guide portion for guiding the landing door 9, and the cross-sectional shape may be other than an L-shape. The method of fixing the landing sill guide 24A to the landing sill main body 23A is not particularly limited as long as it is not a method of interfering with the guidance of the landing door 9 when the landing door 9 is opened and closed.
As shown in fig. 6, the landing sill guide 24A is configured to form an air passage in the vertical direction of the hoistway when the landing sill 22 is viewed in the vertical direction. That is, the landing sill guide 24 is configured such that the sum of the cross-sectional areas of the landing sill main body 23 and the landing sill guide 24 when the landing sill 22 is viewed from the vertical direction is smaller than the cross-sectional area of the landing sill main body 23 when the landing sill 22 is viewed from the vertical direction when the landing sill main body 23 is extended to the end of the landing sill guide 24.
By thus configuring the landing sill guide 24, the flow area of the air around the landing sill guide 24 is enlarged. When the elevator is operated, the car sill 15 approaches the landing sill 22, and noise is generated due to air turbulence, but by providing the landing sill guide 24 of the present embodiment, the flow area of air around the landing sill guide 24 is enlarged, and thus noise due to air turbulence when the car sill 15 approaches the landing sill 22 can be reduced. As a result, the silence in the car can be improved.
As described above, in the present embodiment, the elevator door sill including the car sill guide 17 and the landing sill guide 24 is described, but the car sill guide 17 and the landing sill guide 24 may be provided to the elevator door sill 100, either of which may be provided, so that noise caused by air turbulence when the car sill 15 and the landing sill 22 approach each other can be reduced. Further, by providing the car sill guide 17 to the sill of the elevator door only in the car, noise due to air turbulence when the car sill 15 approaches the landing sill 22 can be reduced at a lower cost than when the landing sill guide 24 is provided only in the landing. As described in the present embodiment, the silence in the car can be further improved by providing the car sill guide 17 and the landing sill guide 24.
The car sill guide 17 and the landing sill guide 24 are each configured as a guide having an L-shaped cross section, but the present invention is not limited thereto, and various shapes can be adopted as long as the flow area of air around the car sill guide 17 and the landing sill guide 24 can be enlarged. Further, by providing the rib on the guide of each guide portion, the strength against the load acting on the guide portion in the up-down direction (vertical direction) can be improved.
Embodiment 2
A sill 100 of an elevator door according to embodiment 2 will be described. Fig. 7 is a diagram showing a part of a top view of the car sill 15 according to embodiment 2. Fig. 8 is a diagram showing a part of a front view of the car sill 15 according to embodiment 2.
In the following description, a configuration different from embodiment 1 will be mainly described, and the same configuration as embodiment 1 will be appropriately omitted. The car sill 15 of embodiment 2 is different from that of embodiment 1 in that a car sill guide 17 includes a sloping plate 26.
As shown in fig. 7, the car sill 15 is composed of a car sill main body 16 and a car sill guide 17. The structure of the car sill main body 16 is the same as that of embodiment 1, and therefore, the description thereof is omitted. The car sill guide 17 includes a plurality of inclined plates 26. A plurality of inclined plates 26 are provided between the two car sill guides 17A.
As shown in fig. 8, the plurality of inclined plates 26 are inclined in a direction away from the car door 7 when the car door apparatus is viewed from the landing side. By providing the inclined plate 26 in this manner, the air flow around the car sill can be guided along the inclined plate 26 in a direction away from the car when the car 1 is lowered, and the collision noise generated by the collision of the air flowing when the car 1 is lowered with the car can be reduced. Further, by providing the inclined plate 26, the rigidity of the car sill guide 17 can be improved. This can suppress deformation of the car sill 15 due to a load acting in the up-down direction of the car sill 15.
The inclined plate 26 is provided so that the upper end of the inclined plate 26 does not interfere with the door shoe 19 and is located below the lower end of the groove 20 of the car sill main 16. In addition, without providing a plurality of inclined plates 26, by providing at least one inclined plate 26, the air flow around the car sill 15 when the car 1 is lowered can be guided along the inclined plate 26 in a direction away from the car 1. Further, it is not necessarily required that the upper end portion of the inclined plate 26 is located below the lower end portion of the groove 20 of the car sill main portion 16. In this case, the inclined plate 26 may be provided only at a position outside the stroke width when the car door 7 is opened and closed.
The inclined plate 26 can be provided to connect two car sill guides 17A. The inclined plate 26 can be provided to the two car sill guides 17A by welding, for example. The inclined plate 26 may be formed by providing a cutout in the car sill guide 17A formed of one member and bending the cutout. In this case, the number of components of the car sill guide 17 can be reduced, and therefore, the cost can be reduced.
Fig. 9 is a diagram showing a part of a plan view of the car sill 15 and the landing sill 22. As described above, in the present embodiment, the inclined plate 26 similar to the car sill 15 is also provided to the landing sill guide 24 of the landing sill 22. The inclined plate 26 provided in the landing sill guide 24 can have the same configuration as the inclined plate 26 of the landing sill guide 24 described above, and therefore, the description thereof will be omitted. In this way, by providing the inclined plate 26 also in the landing sill guide 24, the flow of air can be guided in a direction away from the car 1, and therefore the collision noise caused by the collision of air with the car 1 can be further reduced.

A sill 100 of an elevator door according to embodiment 3 will be described. Fig. 10 to 12 are diagrams showing a part of a front view of the car sill 15 according to embodiment 3.
In the following description, mainly the configuration different from embodiment 1 and embodiment 2 will be described, and the same configuration as embodiment 1 and embodiment 2 will be omitted as appropriate. The car sill 15 of embodiment 3 is different from the other embodiments in that a tilt plate 26 provided in a car sill guide 17 has a rotation shaft 27 and is rotatable by the rotation shaft 27.
Fig. 10 is a diagram showing a part of a front view of the car sill 15 in which the car 1 is in a stopped state, fig. 11 is a diagram showing a part of a front view of the car sill 15 in which the car 1 is in a raised state, and fig. 12 is a diagram showing a part of a front view of the car sill 15 in which the car 1 is in a lowered state. Fig. 11 and 12 schematically show the direction of the air flow (air flow) when the car 1 is operating. The car sill guide 17 is provided with a plurality of inclined plates 26. The inclined plate 26 includes a rotation shaft 27 at an upper end portion. That is, the plurality of inclined plates 26 have rotation shafts 27 at the upper end portions thereof.
As shown in fig. 10, the inclined plate 26 is configured to be inclined in a direction opposite to the car door 7 when the car 1 is stopped. The inclined plate 26 is configured to be inclined by an urging member 28 such as a spring or a magnet when the car 1 is stopped, for example. In the present embodiment, a spring is provided as the urging body 28. The inclined plate 26 maintains an inclined posture by the elastic force of the spring.
As shown in fig. 11, the inclined plate 26 receives wind pressure from the upper side to the lower side when the car 1 is lifted. As a result, the inclined plate 26 rotates clockwise on the axis of the rotation shaft 27, and a spring (not shown) connected to the inclined plate 26 extends, so that the inclined plate 26 stops at a position in a vertical posture of 90 degrees with respect to the horizontal direction. The inclined plate 26 is kept in a vertical posture by balancing the force of wind received from the air and the elastic force of the spring when the car 1 is lifted. As a result, when the car 1 is lifted, the inclined plate 26 guides the flow of air downward, so that the flow of air toward the car, which occurs when the inclined plate 26 is inclined, can be suppressed, and the collision noise generated by the collision of air with the car can be reduced. The car sill guide 17 may further include a locking member 29 for locking the inclined plate 26. In this way, the inclined plate 26 can be locked in a position in the vertical posture by rotation due to wind power received from the air. The locking member 29 may be made of a metal member, for example.
As shown in fig. 12, the inclined plate 26 maintains an inclined posture toward the end side of the car sill 15 when the car 1 descends. Accordingly, when the car 1 descends, the flow of air around the car sill 15 can be guided along the inclined plate 26 in a direction away from the car, and the collision noise generated by the collision of the air with the car in the direction toward the car 1 can be reduced.
The car sill guide 17 includes a locking member 29 for locking the rotation of the inclined plate 26. When the car 1 descends, the inclined plate 26 receives wind pressure from the air flowing from the lower side to the upper side and rotates about the rotation shaft 27, but the rotation of the inclined plate 26 can be locked by the locking member 29 provided in the car sill guide 17. That is, the angle of inclination of the inclined plate 26 by the rotation operation can be adjusted by adjusting the position of the locking member 29. This can further reduce the collision noise generated by the collision of the air in the direction toward the car 1 with the car.
Although the embodiments of the present disclosure have been described above, the sill 100 of the elevator door of the present disclosure is not limited to the embodiments described in embodiments 1 to 3, but represents a part of the present disclosure. The sill 100 of the elevator door of the present disclosure may be combined with other known technologies, and a part of the structure may be omitted or changed, for example, combined appropriately, without departing from the scope of the present disclosure.
