Detailed Description
Embodiment mode 1
Fig. 1 is a front view showing an elevator door rail cleaning aid according to embodiment 1 of the present invention. Fig. 2 is a perspective view showing key parts of the door guide rail cleaning aid of the elevator of fig. 1. Fig. 3 is a perspective view showing key parts of the door guide rail cleaning aid of the elevator of fig. 1. Fig. 4 is a perspective view illustrating key parts of the door guide rail cleaning aid of the elevator of fig. 1. An elevator door rail cleaning aid 1A according to embodiment 1 of the present invention includes a cleaning aid body 11 attached to a door rail 2, and a handle 12 attached to the cleaning aid body 11. In fig. 2 and 4, the handle 12 is not shown.
The door guide rails 2 include a landing side door guide rail and a car side door guide rail. The cleaning in the case where the door rail 2 is a landing side door rail includes cleaning performed by an operator riding on a car and cleaning performed by an operator entering the car. Cleaning in the case where the door rail 2 is a car-side door rail is performed by an operator standing at a landing.
The cleaning tool body 11 includes a base 111, a side wall 112 provided on the base 111, and a movable portion 113 provided on the side wall 112 so as to be rotatable. The cleaning aid body 11 is made of metal, carbon, or the like.
When the cleaning tool body 11 is attached to the door rail 2, the base 111 is provided to face the lower surface of the door rail 2. The lower end of the side wall portion 112 is connected to the base portion 111. In other words, the side wall portion 112 is disposed to extend vertically upward from the base portion 111.
When the cleaning tool body 11 is attached to the door rail 2, the side wall portion 112 is provided to face the side surface of the door rail 2. The side wall portion 112 is fixed to the base portion 111. Movable portion 113 is connected to the upper end of side wall portion 112.
The movable portion 113 rotates relative to the side wall portion 112, whereby the movable portion 113 moves between the attachment position and the release position. When the cleaning assistant device body 11 is attached to the door rail 2 and the position of the movable portion 113 is the attachment position, the movable portion 113 is provided so as to face the upper surface of the door rail 2. On the other hand, when the cleaning assistant device body 11 is attached to the door rail 2 and the position of the movable portion 113 is the release position, the movable portion 113 is provided so as to extend along the side wall portion 112. In fig. 2, the position of the movable portion 113 is the mounting position, and in fig. 4, the position of the movable portion 113 is the release position.
The cleaning tool body 11 includes a spring, not shown, that presses the movable portion 113 in a direction to move the position of the movable portion 113 from the release position to the attachment position. Therefore, when the cleaning assistant device body 11 is attached to the door rail 2 and the position of the movable portion 113 is the attachment position, the movable portion 113 is pressed toward the upper surface of the door rail 2 by the elastic force of the spring. The spring is disposed across the side wall portion 112 and the movable portion 113.
The cleaning aid body 11 includes a stopper, not shown, that maintains the position of the movable portion 113 at the release position against the elastic force of the spring. The force of the stopper is released by applying a force larger than that of the stopper that maintains the position of the movable portion 113 at the release position. As a result, the movable portion 113 moves from the release position to the attachment position by the elastic force of the spring. Therefore, only when the cleaning assistant device body 11 is attached to the door rail 2 and the position of the movable portion 113 is the attachment position, the spring presses the movable portion 113 toward the upper surface of the door rail 2.
The door rail 2 includes a lower plate portion 21, a vertical plate portion 22 fixed to the lower plate portion 21, and an upper plate portion 23 fixed to the vertical plate portion 22. The lower plate portion 21 is formed with the lower surface of the door rail 2. The lower end of the vertical plate 22 is connected to the lower plate 21. In other words, the vertical plate portion 22 is disposed to extend vertically upward from the lower plate portion 21. The upper plate portion 23 is connected to the upper end portion of the vertical plate portion 22. The upper plate portion 23 is formed with an upper surface of the door rail 2.
The lower surface of the door rail 2 is disposed along a horizontal plane. The upper surface of the door rail 2 is formed to be curved with respect to a horizontal plane such that a middle portion in the width direction is disposed above both end portions. The door rail 2 is configured to extend in the widthwise direction of the elevator door.
When the cleaning aid body 11 is attached to the door rail 2 and the position of the movable portion 113 is the attachment position, the surface of the movable portion 113 facing the upper surface of the door rail 2 is formed along the upper surface of the door rail 2.
The base 111 has a groove 114 into which the lower plate portion 21 is fitted. The lower plate portion 21 is fitted into the groove 114, whereby the movement of the cleaning assistant device body 11 relative to the door rail 2 in the plate thickness direction of the door rail 2 is restricted. In other words, the lower plate portion 21 is fitted into the groove 114, and the movement of the cleaning assistant device body 11 relative to the door rail 2 is restricted in the depth direction of the elevator door.
The distal end portion of the shank 12 is rotatably attached to the side wall portion 112. The rotation axis of the handle portion 12 relative to the side wall portion 112 includes a rotation axis extending in a direction perpendicular to the side wall portion 112 and a rotation axis extending in a direction along the side wall portion 112. Therefore, the shank portion 12 can rotate with respect to the side wall portion 112 about a rotation axis perpendicular to the side wall portion 112, and can rotate with respect to the side wall portion 112 about a rotation axis along the side wall portion 112. The base end of the handle 12 is held by the operator.
The distal end of the handle 12 may be detachably attached to the side wall 112. The tip of the shank 12 may be attached to the base 111. In this case, the distal end portion of the handle 12 may be detachably attached to the base 111. In this case, the distal end portion of the handle 12 may be selectively attached to both the base portion 111 and the side wall portion 112. In this case, the distal end portion of the shank 12 is selectively attached to both the base portion 111 and the side wall portion 112 in accordance with the positional relationship between the operator and the door rail 2.
Next, cleaning of the door rail 2 using the door rail cleaning aid 1A of the elevator will be described. First, a procedure of attaching the door rail cleaning aid 1A of the elevator to the door rail 2 will be described. Fig. 5 is a side view showing a step of attaching the door rail cleaning aid 1A of the elevator of fig. 1 to the door rail 2. In fig. 5, the handle 12 is not shown. In fig. 5, 2 door rails 2 are arranged side by side with each other in the width direction of the door rail 2. The dimension L1 between the 2 door rails 2 is smaller than the dimension L2 from the base end portion of the movable portion 113 to the tip end portion of the movable portion 113. Here, the proximal end of the movable portion 113 is an end of the movable portion 113 on the side of the side wall 112, and the distal end of the movable portion 113 is an end of the movable portion 113 on the opposite side of the proximal end. The dimension L1 between the 2 door rails 2 is larger than the dimension L3 in the thickness direction of the movable portion 113. The number of the door rails 2 is not limited to 2, and may be 3 or more.
When the door rail cleaning aid 1A of the elevator is attached to the door rail 2, first, the operator sets the position of the movable portion 113 to the release position. After that, the operator passes the movable portion 113 between the 2 door rails 2.
After that, the operator moves the movable portion 113 from the release position to the attachment position. Thereby, the movable portion 113 contacts the upper surface of the door rail 2, and the base portion 111 contacts the lower surface of the door rail 2. The position of the movable portion 113 is set to the mounting position, and thereby the movable portion 113 is pressed toward the upper surface of the door rail 2. Thereby, the base 111 is pressed toward the lower surface of the door rail 2. As a result, the door rail cleaning aid 1A of the elevator is attached to the door rail 2.
After the door rail cleaning aid 1A of the elevator is attached to the door rail 2, the operator holds the base end portion of the handle 12 and moves the cleaning aid body 11 in the lateral width direction of the elevator. Thereby, the upper surface of the door rail 2 and the lower surface of the door rail 2 are cleaned.
The cleaning of the upper surface of the door guide 2 includes the removal of foreign matter such as solidified oil and dust adhering to the upper surface of the door guide 2. Foreign matter adhering to the upper surface of the door rail 2 is removed from the upper surface of the door rail 2 by the corner of the movable portion 113 constituted by the surface of the movable portion 113 facing forward in the moving direction of the cleaning assistant body 11 and the surface of the movable portion 113 facing the upper surface of the door rail 2.
The cleaning of the lower surface of the door guide 2 includes the removal of foreign matter such as dust attached to the lower surface of the door guide 2. Foreign matter adhering to the lower surface of the door rail 2 is removed from the lower surface of the door rail 2 by the corner portion of the base 111 constituted by the surface of the base 111 facing forward in the moving direction of the cleaning aid body 11 and the surface of the base 111 facing the lower surface of the door rail 2.
When cleaning the upper surface of the door rail 2 and the lower surface of the door rail 2, the movable portion 113 is pressed against the upper surface of the door rail 2 and the base portion 111 is pressed against the lower surface of the door rail 2 by the elastic force of the spring. This allows the upper surface of the door rail 2 and the lower surface of the door rail 2 to be cleaned more reliably.
The cleaning of the door guide rail 2 using the door guide rail cleaning aid 1A of the elevator is performed over the entire area of the door guide rail 2 in the lateral width direction of the elevator. Therefore, the longitudinal end of the door rail 2 is also cleaned.
After the cleaning of the door rail 2 is completed, the operator moves the position of the movable portion 113 from the attachment position to the release position. Thus, the door rail cleaning aid 1A of the elevator can be detached from the door rail 2. The cleaning of the door rail 2 is completed by detaching the door rail cleaning aid 1A of the elevator from the door rail 2.
As described above, according to the door rail cleaning aid 1A for an elevator according to embodiment 1 of the present invention, the movable portion 113 rotates with respect to the side wall portion 112, and the movable portion 113 moves between the attachment position and the release position. When the position of the movable portion 113 is set to the release position, the movable portion 113 can more reliably pass between the 2 door rails 2. As a result, the door rail cleaning aid 1A of the elevator can be more reliably attached to the door rail 2.
The door rail cleaning aid 1A of the elevator includes a spring that presses the movable portion 113 toward the upper surface of the door rail 2 when the position of the movable portion 113 is the attachment position. Thus, when the position of the movable portion 113 is the mounting position, the movable portion 113 is pressed against the upper surface of the door rail 2. As a result, the upper surface of the door rail 2 can be cleaned more reliably. Further, the movable portion 113 is pressed toward the upper surface of the door rail 2 by a spring, and the base portion 111 is pressed to the lower surface of the door rail 2. Thereby, the base 111 is pressed to the lower surface of the door rail 2. As a result, the lower surface of the door rail 2 can be cleaned more reliably.
The door rail cleaning aid 1A for an elevator includes a handle 12 provided on a base 111 or a side wall 112. Thus, even when the distance between the operator and the door rail 2 is large, the operator can move the cleaning aid body 11 relative to the door rail 2 by gripping the grip 12.
In embodiment 1, the following configuration is explained: the movable portion 113 contacts the upper surface of the door rail 2, and the base portion 111 contacts the lower surface of the door rail 2, so that the cleaning assistant device body 11 cleans the door rail 2. However, the cleaning aid body 11 may be configured to clean the door rail 2 with a cleaning member such as waste cloth or sandpaper interposed between the movable portion 113 and the upper surface of the door rail 2 and between the base portion 111 and the lower surface of the door rail 2. The cleaning member to be used is selected in accordance with the foreign matter adhering to the upper surface of the door rail 2 and the foreign matter adhering to the lower surface of the door rail 2.
Fig. 6 is a front view showing key parts of an elevator door rail cleaning aid according to embodiment 2 of the present invention. In the door rail cleaning aid 1B for an elevator according to embodiment 2 of the present invention, the handle 12 is formed of a plurality of small pieces 121 divided in the longitudinal direction of the handle 12. In other words, the handle 12 is capable of adjusting the dimension in the length direction of the handle 12.
One of the small parts 121 adjacent to each other in the longitudinal direction of the shank portion 12 is formed with a screw portion, and the other shank portion 12 is formed with a screw groove into which the screw portion is inserted. The screw part is inserted into the screw groove, whereby the pair of small pieces 121 are connected to each other. The other structure is the same as embodiment 2.
As described above, according to the door rail cleaning aid 1B for an elevator according to embodiment 2 of the present invention, the dimension of the shank 12 in the longitudinal direction can be adjusted. Thus, the dimension of the handle 12 in the longitudinal direction can be adjusted according to the distance between the worker and the door rail 2.
In embodiment 2, the description has been given of the shank 12 including the plurality of small pieces 121 divided in the longitudinal direction of the shank 12. However, any handle 12 may be used as long as the dimension in the longitudinal direction of the handle 12 can be adjusted.
Embodiment 3
Fig. 7 is a perspective view showing key parts of an elevator door rail cleaning aid according to embodiment 3 of the present invention. Fig. 8 is a perspective view showing key parts of the door guide rail cleaning aid of the elevator of fig. 7. In the door rail cleaning aid 1C for an elevator according to embodiment 3 of the present invention, the cleaning aid body 11 further includes an oil filler 115. The oil feeding member 115 is detachably attached to the movable portion 113. When the cleaning assistant device body 11 is attached to the door rail 2 and the position of the movable portion 113 is the attachment position, the oil feeding member 115 comes into contact with the upper surface of the door rail 2. The oil feed member 115 is made of, for example, waste cloth containing lubricating oil.
Further, an oil passage 116 through which the lubricating oil supplied to the oil supply member 115 flows is formed in the movable portion 113. The oil flow path 116 is formed to penetrate the movable portion 113 in the thickness direction of the movable portion 113. Accordingly, when the position of the movable portion 113 is the attachment position, the worker supplies the lubricant oil to the oil passage 116, and the lubricant oil is supplied to the oil feeding member 115. The lubrication oil is supplied to the oil flow path 116 by an operator using a bell mouth.
The supply of the lubricating oil to the upper surface of the door guide 2 is performed after the cleaning of the upper surface of the door guide 2 is completed. The supply of the lubricating oil to the upper surface of the door rail 2 may be performed without cleaning the upper surface of the door rail 2.
After the supply of the lubricant oil to the upper surface of the door rail 2 is completed, the cleaning assistant device body 11 may be moved in the lateral width direction of the elevator door in a state where an oil wiping member such as a waste cloth is disposed between the upper surface of the door rail 2 and the movable portion 113. Thereby, an excessive amount of the lubricating oil supplied to the upper surface of the door guide rail 2 is removed. As a result, the lubricating oil is prevented from flowing down from the upper surface of the door rail 2. The other structure is the same as that of embodiment 1 and embodiment 2.
As described above, the door rail cleaning aid 1C for an elevator according to embodiment 3 of the present invention includes the fueling member 115, and the fueling member 115 is provided on the movable portion 113, and contacts the upper surface of the door rail 2 when the position of the movable portion 113 is the installation position. This enables the lubricating oil to be supplied to the upper surface of the door rail 2.
Further, an oil passage 116 through which the lubricating oil supplied to the oil supply member 115 flows is formed in the movable portion 113. This facilitates the supply of the lubricating oil to the oil filler 115.
Embodiment 4
Fig. 9 is a side view showing a key part of an elevator door rail cleaning aid according to embodiment 4 of the present invention. In the door rail cleaning aid 1D for an elevator according to embodiment 4 of the present invention, the cleaning aid body 11 includes the opening/closing portion 117 provided in the side wall portion 112.
The force of the stopper that maintains the position of the movable portion 113 at the release position is released by operating the switch portion 117. Therefore, the movable portion 113 is moved from the release position to the attachment position by operating the switch portion 117.
When the side wall portion 112 is adjacent to the vertical plate portion 22, the switch portion 117 is operated by the vertical plate portion 22. Therefore, when the movable portion 113 located at the release position passes between the 2 door rails 2, the side wall portion 112 is pressed toward the vertical plate portion 22, and the opening/closing portion 117 is operated, so that the movable portion 113 moves from the release position to the attachment position. The other configurations are the same as those in embodiment 1, embodiment 2, and embodiment 3.
As described above, the door rail cleaning aid 1D for an elevator according to embodiment 4 of the present invention further includes the switch unit 117 that moves the movable unit 113 from the release position to the attachment position when operated. Thus, the operator can easily move the movable portion 113 from the release position to the attachment position by operating the switch portion 117.
Further, the switch portion 117 is provided to the side wall portion 112 in such a manner that the switch portion 117 is operated by the vertical plate portion 22 with the side wall portion 112 adjacent to the vertical plate portion 22. Therefore, the operator operates the switch unit 117 by bringing the side wall portion 112 into proximity with the vertical plate portion 22. As a result, the movable portion 113 can be easily moved from the release position to the attachment position.
In embodiment 4, the configuration of the cleaning assistant tool body 11 in which the switch 117 is operated by the vertical plate portion 22 is described. However, the cleaning tool may be a cleaning tool main body 11 in which the opening and closing unit 117 is operated by an operator, for example.
