  Hereinafter, an elevator sill groove cleaning tool and a cleaning method according to an embodiment will be described with reference to the drawings.

(Embodiment)
Drawing 1 is a figure showing an example of elevator sill groove cleaning tool 1 concerning an embodiment. As shown in FIG. 1, the elevator sill groove cleaning tool 1 is rod-shaped and has a brush 11 at one end and a flat plate portion 12 at the other end. Moreover, the elevator sill groove cleaning tool 1 has a main body 13 that connects between the brush 11 and the flat plate portion 12. Further, the elevator sill groove cleaning tool 1 has a hook 14 on the main body 13.

  As shown in FIG. 1, the brush 11 includes bristles 11a and connecting portions 11b. The hair 11a may be a chemical fiber such as nylon or polypropylene, or may be a fiber collected from a plant such as tampico or palm. The connection part 11 b bundles the hairs 11 a and connects the hairs 11 a to the main body part 13. The brush 11 may be formed integrally with the main body 13 or may be detachably connected to the main body 13. That is, the brush 11 may be replaceable.

  The flat plate portion 12 is located at one end of the elevator sill groove cleaning tool 1 and includes a rectangular metal plate having a straight tip. Further, the flat plate portion 12 has edges on two sides along the longitudinal direction of the elevator sill groove cleaning tool 1 among the sides of the rectangular metal plate. That is, the flat plate portion 12 shown in FIG. 1 has a U-shape when viewed from the longitudinal direction. Although FIG. 1 shows the case where the flat plate portion 12 is formed integrally with the main body portion 13, the flat plate portion 12 may be detachably connected to the main body portion 13. That is, the flat plate portion 12 may be exchangeable.

  The main body portion 13 is a bar that connects the brush 11 and the flat plate portion 12. For example, the main body portion 13 is a pipe made of the same metal as the flat plate portion 12. The main body 13 is provided with a hook 14. For example, when the elevator sill groove cleaning tool 1 is not used, the elevator sill groove cleaning tool 1 can be easily stored by hooking the hook 14 on a protrusion on the wall.

  Next, cleaning using the elevator threshold groove cleaning tool 1 will be described with reference to FIG. Drawing 2 is a figure showing an example of use of elevator sill groove cleaning tool 1 concerning an embodiment. In the following description, the groove for opening / closing the car door and the groove for opening / closing the floor door are collectively referred to simply as the threshold groove 2.

  Various dirt accumulates in the threshold groove 2. For example, in the threshold groove 2, dirt that adheres strongly due to drinking water or the like spilled by an elevator user accumulates in addition to sand dust. In the following, as shown in FIG. 2, dirt (such as sand dust) that is not strongly adhered in the sill groove 2 is referred to as first dirt 31. Also, the dirt (drinking water or the like) strongly adhered in the sill groove 2 is defined as the second dirt 32.

  For example, the worker who performs cleaning first scrapes the first dirt 31 in the sill groove 2 using the brush 11 of the elevator sill groove cleaning tool 1. Next, the worker collects the first dirt 31 that has been scraped by using the flat plate portion 12 of the elevator sill groove cleaning tool 1. That is, the worker collects sand dust and the like in the sill groove 2 with the brush 11, scoops it with the flat plate portion 12, and discharges it.

  Here, the second dirt 32 strongly adhered in the sill groove 2 cannot normally be scraped by the brush 11. That is, since the strength of the bristles 11 a is lost due to the adhesion of the second dirt 32, the second dirt cannot be peeled from the sill groove 2 using the brush 11. Therefore, the worker usually scrapes off the second dirt 32 using the metal flat plate portion 12.

  However, when the second dirt 32 is scraped off using the flat plate portion 12, the threshold groove 2 may be damaged. Similarly, when the hair 11a is made of metal and the second dirt 32 is scraped off using the brush 11, the threshold groove 2 may be similarly damaged.

  Therefore, as shown in FIG. 3, the elevator sill groove cleaning tool 1 includes a sponge 15 that can be attached to and detached from the brush 11. The sponge 15 is, for example, a melamine sponge made from melamine resin. In addition, FIG. 3 is a figure which shows an example of the elevator threshold groove cleaning tool 1 which concerns on embodiment.

  For example, the worker first cleans the first dirt 31 using the brush 11 and the flat plate portion 12. Next, the worker attaches the sponge 15 to the brush 11. For example, the worker attaches the sponge 15 to the brush 11 by inserting the hair 11 a of the brush 11 into the sponge 15.

  Here, the hair 11a is produced so as to be harder than the sponge 15. Specifically, the thickness, tip shape, material, and the like of the hair 11a are selected so that the hair 11a can be easily inserted into the sponge 15. Thereby, the operator can easily insert the hair 11a into the sponge 15 and attach the sponge 15 to the brush 11.

  Here, the cleaning using the elevator sill groove cleaning tool 1 in a state where the sponge 15 is mounted will be described with reference to FIG. Drawing 4 is a figure showing an example of use of elevator sill groove cleaning tool 1 concerning an embodiment. For example, the worker first wets the sponge 15 with water. Next, as shown in FIG. 4, the worker inserts the sponge 15 into the sill groove 2 and rubs the second dirt 32 with the sponge 15. Here, the sponge 15, which is a melamine sponge, can scrape off the second dirt 32 and peel the second dirt 32 from the threshold groove 2. Although the sponge 15 is worn by use, the worn sponge 15 can be easily replaced.

  When the second dirt 32 is a small amount, the sponge 15 can absorb the peeled second dirt 32. That is, the worker can remove the second dirt 32 using only the sponge 15. In addition, when the second dirt 32 is large, a part of the second dirt 32 peeled off by the sponge 15 may remain in the sill groove 2. In this case, the worker can collect the peeled second dirt 32 using the flat plate portion 12.

  As described above, the elevator sill groove cleaning tool 1 is a rod-shaped elevator sill groove cleaning tool having the brush 11 at one end and the flat plate portion 12 at the other end. Further, the elevator sill groove cleaning tool 1 includes a sponge 15 that can be attached to and detached from the brush 11. Thereby, the elevator sill groove cleaning tool 1 which concerns on embodiment makes it possible to clean without damaging the sill groove 2. FIG. In other words, the elevator sill groove cleaning tool 1 can clean both the first dirt 31 and the second dirt 32 without damaging the sill groove 2.

  Furthermore, by cleaning with the sponge 15, the sill groove 2 can be made a more beautiful finish. That is, when cleaning with the sponge 15, not only the second dirt 32 caused by drinking water but also various kinds of dirt (such as rust and scale) that are difficult to remove with the brush 11 can be removed.

  According to at least one embodiment described above, cleaning can be performed without damaging the sill groove.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
