Detailed Description
A mode for carrying out the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and overlapping description is simplified or omitted as appropriate.
Embodiment 1.
Fig. 1 is a rear view of an elevator door of embodiment 1.
In fig. 1, a door 1 of an elevator is shown. An elevator is installed in a building having a plurality of floors. In a building, a hoistway is provided across a plurality of floors. An elevator is an apparatus for transporting a user or the like between a plurality of floors by a car traveling in a vertical direction inside a hoistway. The car is provided with a car door. The car door is a device that can be opened and closed by a user so as to be able to move up and down the car. The car door is an example of a door 1 of an elevator. Each of a plurality of floors of a building is provided with a landing. Landing doors are provided in the landings. A landing door is a device that opens and closes in conjunction with the opening and closing of a car door so that a user can get on and off a car that stops at a floor where the landing is installed. The landing door is an example of a door 1 of an elevator. In this example, the doors 1 of the elevator are double-acting doors.
Hereinafter, description will be given using an xyz rectangular coordinate system set as follows. The y-axis direction is the vertical direction. The xz plane is a horizontal plane. The direction of the z-axis is the opening and closing direction of the door 1.
The door 1 includes a door hanger 2, a pair of door panels 3, and a sill 4. The door hanger 2 is provided at an upper portion of the door 1. The door hanger 2 extends in the opening and closing direction of the door 1. The pair of door panels 3 are plate-like devices, respectively. The thickness direction of each of the pair of door panels 3 is oriented in the x-axis direction. The pair of doors 1 are provided with door shoes 5, respectively. The door shoe 5 is provided at the lower end portion of the door panel 3. The upper ends of the pair of door panels 3 are hung on the door hanger 2. The load of the pair of door panels 3 is supported by the door hanger 2. The pair of door panels 3 move along the door hanger 2 when the door 1 is opened and closed, respectively. At this time, the pair of door panels 3 move in opposite directions to each other. The doorsill 4 is provided at a lower portion of the door 1. The doorsill 4 extends in the opening and closing direction of the door 1. The sill 4 has a sill trough 6. The floor groove 6 is a groove long in the opening/closing direction of the door 1. The floor groove 6 is a groove for guiding the door shoe 5 inserted from above when the door 1 is opened and closed.
Fig. 2 isbase:Sub>A sectional viewbase:Sub>A-base:Sub>A in fig. 1 of the door shoe of embodiment 1.
The sill 4 has a side wall 7 in the sill trough 6. The side wall 7 is a wall surface that is long in the opening and closing direction of the door 1. The sill 4 may be provided with a hole, not shown, in the bottom surface of the sill groove 6. Foreign matter entering the floor trough 6 is discharged, for example, from holes in the bottom surface.
The door shoe 5 includes a mounting portion 8 and a sliding portion 9.
The mounting portion 8 is a portion provided at the lower end portion of the door panel 3. The mounting portion 8 is a plate-like member or the like mounted to the door panel 3 by a screw or the like, for example.
The sliding portion 9 is a portion that is disposed so as to be inserted into the floor groove 6 from above. The sliding portion 9 is attached to the lower end of the mounting portion 8. The sliding portion 9 is formed of, for example, resin. The lower surface 9a of the slide portion 9 is disposed below the upper end of the sill groove 6. The side surface 9b of the slide portion 9 faces the side wall 7 of the sill groove 6. The upper surface 9c of the sliding portion 9 may be disposed above or below the upper end of the sill groove 6.
Fig. 3 is a perspective view of the door shoe 5 according to embodiment 1.
The sliding portion 9 has a first flow path 10 on the side surface 9 b. The first flow path 10 extends downward from the upper surface 9c of the sliding portion 9 on the side surface 9b of the sliding portion 9. In this example, the first flow path 10 reaches the lower surface 9a of the sliding portion 9 from the upper surface 9c of the sliding portion 9. The first flow path 10 is, for example, a vertically long concave portion. In this example, the first flow path 10 is a vertically long groove. In this example, the shape of the first flow path 10 in the horizontal cross section of the sliding portion 9 is rectangular. Here, each side of the rectangle corresponds to the bottom surface 10a or the side surface 10b of the first channel 10.
The sliding portion 9 has an antifouling coating 11 on the upper surface 9c. The sliding portion 9 has an antifouling coating layer 11 in the first flow path 10. The antifouling coating layer 11 is a layer formed by antifouling coating. An anti-fouling coating is a coating that increases the hydrophobicity of a surface. Here, the hydrophobicity of the surface can be indicated by, for example, a contact angle of water. The antifouling coating may be a coating with a fluororesin, for example.
Next, the operation of the door shoe 5 of embodiment 1 will be described.
When the door 1 is opened and closed, the door shoe 5 is guided by the sill groove 6. This can suppress the inclination of the door panel 3 when the door 1 is opened and closed. At this time, the side surface 9b of the sliding portion 9 of the door shoe 5 moves in the opening and closing direction while contacting the side wall 7 of the sill groove 6. The area of the portion of the side surface 9b of the sliding portion 9 that contacts the side wall 7 of the sill groove 6 is smaller than the area obtained by projecting the sliding portion 9 onto the side wall 7 of the sill groove 6 by the first flow path 10. Therefore, the frictional resistance between the side surface 9b of the sliding portion 9 and the side wall 7 of the sill groove 6 is reduced by the first flow path 10. This can suppress resistance applied to the door shoe 5 during opening and closing of the door 1.
In addition, in the elevator, liquid may enter the sill groove 6 of the sill 4. The liquid is, for example, a drink or the like that overflows inside the hall or the car. Alternatively, the liquid is rainwater, muddy water, or the like attached to the user's umbrella, shoes, or the like. At this point, the liquid enters the floor trough 6 from above. Here, the liquid entering the floor trough 6 sometimes adheres to the door shoes 5.
The liquid attached to the door shoe 5 is attached to the upper surface 9c of the door shoe 5. Due to the antifouling coating 11 of the upper surface 9c of the door shoe 5, the liquid flows without being stagnant. Therefore, the liquid flows down from the end of the door shoe 5 in the opening and closing direction of the door 1. Further, the liquid also flows into the first flow path 10 from the upper surface 9c. The liquid flows down the first flow path 10 without being retained by the antifouling coating layer 11 of the first flow path 10.
Thus, the stagnation of the liquid attached to the door shoe 5 can be suppressed. In addition, since the first flow path 10 suppresses the liquid attached to the door shoe 5 from staying, the liquid is suppressed from entering between the side surface 9b of the sliding portion 9 and the side wall 7 of the sill groove 6. Therefore, resistance can be prevented from being applied to the opening and closing of the door 1 due to the viscous resistance of the liquid accumulated in the door shoe 5. In addition, the liquid retained in the door shoe 5 can be prevented from becoming a sticky substance with time. Therefore, resistance can be prevented from being applied to the opening and closing of the door 1 due to the adhesive attached to the door shoe 5. Here, when the liquid is accumulated in the door shoe 5, there is a case where resistance is generated to the opening and closing of the door 1 by the liquid between the side surface 9b of the entry sliding portion 9 and the side wall 7 of the sill groove 6. This resistance is for example the resistance created by the fluid between 2 plates. It is known through experimentation that the resistance between 2 plates is proportional to the area of the plate that is in contact with the fluid and inversely proportional to the spacing of the plates. In the door shoe 5, the area of the sliding portion 9 in contact with the side wall 7 is reduced by the first flow path 10, and therefore, even if liquid enters, resistance to opening and closing of the door 1 is reduced. Further, when the liquid entering the door becomes an adhesive having adhesiveness with the passage of time, the resistance of the adhesive to the opening and closing of the door 1 is also reduced.
As described above, the door shoe 5 of embodiment 1 includes the mounting portion 8 and the sliding portion 9. The mounting portion 8 is provided at a lower end portion of the door panel 3 of the elevator. The sliding portion 9 is attached to the attachment portion 8. The sliding part 9 is arranged in the floor groove 6. The floor groove 6 is a groove long in the opening/closing direction of the door 1. The side surface 9b of the slide portion 9 faces the side wall 7 of the sill groove 6. A first flow path 10 is provided on the side surface 9b of the sliding portion 9. The first flow path 10 extends downward from the upper surface 9c of the sliding portion 9.
This makes it difficult for liquid to accumulate in the door shoe 5. Therefore, the door shoe 5 is less likely to receive resistance due to viscous resistance of liquid or the like.
Further, the first flow path 10 reaches the lower surface 9a of the sliding portion 9 from the upper surface 9c of the sliding portion 9 on the side surface 9b of the sliding portion 9. Therefore, the liquid flowing through the first flow path 10 is discharged to the lower side of the sliding portion 9. The liquid discharged to the lower side of the sliding portion 9 is difficult to be attached to the sliding portion 9 again. Therefore, the door shoe 5 is less likely to be subjected to resistance caused by viscous resistance of liquid or the like.
The first flow path 10 may extend from the upper surface 9c of the slide portion 9 to a lower portion of an end portion of the slide portion 9 in the opening/closing direction. When the liquid flowing through the first flow path 10 is discharged from the rear side in the direction in which the sliding portion 9 moves, the discharged liquid is less likely to be attached to the sliding portion 9 moving when the door 1 is opened and closed again.
Further, the sliding portion 9 has an antifouling coating 11 on the upper surface 9c. This makes it more difficult for the liquid to stay on the upper surface 9c of the sliding portion 9.
The sliding portion 9 has an antifouling coating layer 11 in the first flow path 10. This makes it more difficult for the liquid to stay in the first flow path 10. Even when the width of the first flow path 10 in the opening/closing direction of the door 1 is narrow, the liquid flows down rapidly through the first flow path 10. Therefore, the change of the liquid to the stuck material can be more effectively prevented.
Further, the sliding portion 9 may not have the antifouling coating 11. In this case, the liquid may be prevented from staying by the hydrophobic property of the material itself, such as the resin forming the sliding portion 9. The antifouling coating layer 11 may be provided on either the upper surface 9c of the sliding portion 9 or the first flow path 10. Alternatively, the antifouling coating layer 11 may be provided on the entire surface of the sliding portion 9.
In this example, the sliding portion 9 is configured to be symmetrical with respect to a vertical plane parallel to the yz plane. The sliding portion 9 has first flow paths 10 symmetrically to each other on side surfaces 9b on both sides facing the side walls 7 of the sill groove 6. Here, the sliding portion 9 may have the first flow paths 10 asymmetrically with respect to each other on both side surfaces 9 b. The sliding portion 9 may have the first flow channel 10 only on one side surface 9 b. For example, when the door 1 is a car door, the sliding portion 9 may have the first flow path 10 only on the side surface 9b facing the inside of the car. Alternatively, when the door 1 is a landing door, the sliding portion 9 may have the first flow path 10 only on the side surface 9b facing the landing side.
In addition, the elevator door 1 may be a single-opening door. The elevator door 1 may be a door including 2 or 3 door panels 3 that move in the same direction when the door 1 is opened or closed.
Next, a modification of embodiment 1 will be described with reference to fig. 4.
Fig. 4 is a perspective view of a door shoe according to a modification of embodiment 1.
In this example, the first flow channel 10 has a trapezoidal shape in a horizontal cross section of the sliding section 9. Here, the upper base or the lower base of the trapezoid corresponds to the bottom surface 10a of the first flow path 10. The oblique side of the trapezoid corresponds to the side face 10b of the first flow path 10.
In the sliding portion 9, the first flow path 10 is provided so as to widen outward in the width in the opening/closing direction of the door 1. In this example, the side surface 10b of the first channel 10 is formed at an obtuse angle with respect to the bottom surface 10a of the first channel 10. This can prevent the liquid from staying in the first channel 10 due to surface tension or the like.
The first flow path 10 is not limited to a groove having a trapezoidal shape in a horizontal cross section of the sliding portion 9. The first flow path 10 may be a groove having a smooth shape such as an arc shape in a horizontal cross section of the sliding portion 9. The shape of the first channel 10 may be asymmetrical with respect to a vertical plane parallel to the xy plane.
Next, another modification of embodiment 1 will be described with reference to fig. 5.
Fig. 5 is a perspective view of a door shoe according to a modification of embodiment 1.
The sliding portion 9 has a fine structure on the upper surface 9c. The sliding portion 9 has a fine structure in the first flow path 10. The fine structure is a structure in which the hydrophobicity of the surface is enhanced by a lotus effect or the like based on the surface structure, for example. The fine structure is, for example, fine protrusions 12 arranged on the surface. The size of the minute projection 12 is, for example, in the order of micrometers. In fig. 5, the minute protrusions 12 are enlarged for illustration.
Thus, the sliding portion 9 has a fine structure with improved hydrophobicity on the upper surface 9c. This makes it more difficult for the liquid to stay on the upper surface 9c of the sliding portion 9.
The sliding portion 9 has a fine structure with improved hydrophobicity in the first flow channel 10. This makes it more difficult for the liquid to stay in the first flow path 10. Even when the width of the first flow path 10 in the opening/closing direction of the door 1 is narrow, the liquid flows down rapidly in the first flow path 10. Therefore, the change of the liquid to the adhered can be more effectively prevented.
Further, the fine structure may be provided on either the upper surface 9c of the sliding portion 9 or the first flow path 10. Alternatively, the fine structure may be provided on the entire surface of the sliding portion 9. When the sliding portion 9 has the antifouling coating layer 11, a fine structure may be provided on the antifouling coating layer 11.
Next, another modification of embodiment 1 will be described with reference to fig. 6.
Fig. 6 is a perspective view of a door shoe according to a modification of embodiment 1.
A second flow channel 13 is further provided on the side surface of the sliding portion 9 on which the first flow channel 10 is provided. The second flow path 13 extends downward from the upper surface 9c of the sliding portion 9. The second flow path 13 is, for example, a vertically long concave portion. In this example, the second flow path 13 is a vertically long groove. Thereby, the liquid attached to the door shoe 5 flows down both of the first flow path 10 and the second flow path 13. Therefore, it is more difficult for the liquid to stay in the door shoe 5.
In this example, the second flow path 13 reaches the lower surface 9a of the sliding portion 9 from the upper surface 9c of the sliding portion 9. The second channel 13 is formed, for example, in the same manner as the first channel 10.
Further, 3 or more flow paths extending downward from the upper surface 9c may be provided on the side surface 9b of the sliding portion 9.
Next, another modification of embodiment 1 will be described with reference to fig. 7.
Fig. 7 is a perspective view of a door shoe according to a modification of embodiment 1.
The depth of the first flow path 10 in the x direction may be the depth from the side surface 9b of the sliding portion 9 to the mounting portion 8. In this example, the slide 9 has a first portion 14a and a second portion 14b. The first part 14a and the second part 14b are 2 parts of the sliding section 9 divided in the opening and closing direction of the door 1. The first flow path 10 may be a gap between the first portion 14a and the second portion 14b.
In embodiment 2, points different from the example disclosed in embodiment 1 will be described in detail. As for the features not described in embodiment 2, any of the features in the example disclosed in embodiment 1 can be adopted.
Fig. 8 is a perspective view of the door shoe according to embodiment 2.
A cross flow path 15 at 2 is further provided on the side surface 9b of the sliding portion 9 where the first flow path 10 is provided. The lateral flow path 15 extends in the opening/closing direction of the door 1. The lateral flow path 15 is, for example, a horizontally long groove. The cross flow paths 15 at 2 are connected to the first flow paths 10, respectively. One lateral flow path 15 is connected to the end of the slide portion 9 on the z-axis positive side. The other lateral flow path 15 is connected to the negative z-axis end of the slide unit 9.
The area of the portion of the side surface 9b of the sliding portion 9 that contacts the side wall 7 of the sill groove 6 is further reduced by the lateral flow path 15. Therefore, the frictional resistance between the side surface 9b of the sliding portion 9 and the side wall 7 of the sill groove 6 is further reduced by the lateral flow path 15. This can further suppress resistance applied to the door shoe 5 during opening and closing of the door 1. Further, when the liquid adhesive remains between the side wall 7 of the sill groove 6 and the side surface 9b of the sliding portion 9, the resistance of the remaining liquid adhesive to the opening and closing of the door 1 is also reduced.
Next, a modification of embodiment 2 will be described with reference to fig. 9.
Fig. 9 is a perspective view of a door shoe according to a modification of embodiment 2.
In the sliding portion 9, the cross flow path 15 is connected to the first flow path 10 at 2. The cross flow path 15 at 2 is inclined so as to descend toward the first flow path 10. Thus, even when the liquid enters the cross flow path 15, the liquid is quickly discharged from the first flow path 10.
Next, another modification of embodiment 2 will be described with reference to fig. 10.
Fig. 10 is a perspective view of a door shoe according to a modification of embodiment 2.
In the slide portion 9, one lateral flow path 15 is connected to an end portion of the slide portion 9 on the z-axis positive side. The other lateral flow path 15 is connected to the negative z-axis end of the slide unit 9. The cross flow path 15 connected to the positive side end of the z axis is inclined so as to descend toward the end. The cross flow path 15 connected to the negative side end of the z axis is inclined so as to descend toward the end. Thus, even when the liquid enters the cross flow path 15, the liquid is quickly discharged from the end of the sliding portion 9 in the opening/closing direction of the door 1.
