The door panel 1 of the elevator is installed above the sill 11. As shown in FIG. 1, an elevator sill groove for cleaning a door guide shoe 2 for guiding the movement of the door panel 1 and a groove (hereinafter referred to as “sill groove”) 12 of the sill 11 are provided at the lower part of the door panel 1. A cleaning device 3 is provided. As shown in FIG. 2, two screw holes 1 a for attaching the door guide shoe 2 are formed in the lower portion of the door panel 1. The number of screw holes 1a formed in the door panel 1 is not limited to this, and an arbitrary number may be formed.

  As shown in FIG. 1, the door guide shoe 2 includes an attachment surface 2 a for attaching to the door panel 1 and a guide portion 2 b for guiding the movement of the door panel 1. As shown in FIG. 1, the guide portion 2 b extends from the mounting surface 2 a to the sill groove 12 and is inserted into the sill groove 12. In addition, the shape of the guide part 2b is not limited to the shape shown in FIG. 1, For example, you may be arbitrary shapes, such as a rectangular parallelepiped.

  As shown in FIG. 2, two mounting holes 2 c are formed on the mounting surface 2 a so as to correspond to the two screw holes 1 a of the door panel 1. The door guide shoe 2 is fixed to the door panel 1 by passing bolts (fixing screws) 13 through the two mounting holes 2 c and bolting the screw holes 1 a of the door panel 1. In addition, as shown in FIG. 2, the marking 2d which shows that it is a front surface is engraved on the front surface of the attachment surface 2a.

  Here, in addition to FIG.1 and FIG.2, the elevator sill groove cleaning apparatus 3 is demonstrated with reference to FIGS. 3-5. FIG. 3 is a diagram for supplementarily explaining the characteristics of the elevator sill groove cleaning device 3, FIG. 4 is a diagram showing the front surface of the elevator sill groove cleaning device 3, and FIG. It is a figure which shows the back surface of the elevator threshold groove cleaning apparatus.

  As shown in FIG. 1, the elevator sill groove cleaning device 3 includes a fixing bracket 4, a brush fixing portion 5, and a cleaning brush 6. The fixing bracket 4 is overlapped with the mounting surface 2 a of the door guide shoe 2 and fastened to the door panel 1 together. For this reason, as shown in FIG. 2, two mounting holes 4 a are formed in the fixing bracket 4 so as to correspond to the mounting holes 2 c of the door guide shoe 2 and the screw holes 1 a of the door panel 1. The two mounting holes 4a formed in the fixing bracket 4 are screw holes 1a of the door panel 1 and door guide shoes for position adjustment work performed when the elevator sill groove cleaning device 3 is attached to an existing elevator. It is preferable that the hole is larger than the two mounting holes 2c. According to this, since the height can be adjusted at the time of position adjustment work when the elevator sill groove cleaning device 3 is attached to the existing elevator, the elevator sill groove cleaning device 3 can be of various types. It can be applied to elevators.

  The elevator sill groove cleaning device 3 is fixed to the door panel 1 by passing bolts through these two mounting holes 4 a and fastening together with the door guide shoe 2 in the screw holes 1 a of the door panel 1. That is, the elevator sill groove cleaning device 3 can be attached using the screw holes 1a and the attachment holes 2c that are generally formed in the door panel 1 and the door guide shoe 2 that are originally attached to the existing elevator. Therefore, it can be applied to an existing elevator without requiring dedicated parts. As shown in FIG. 2, the front surface of the fixing metal 4 is engraved with an inscription 4 b indicating that it is a front surface, like the front surface of the door guide shoe 2.

  As shown in FIG. 1, the fixing bracket 4 is provided along the sill groove 12, and has a key shape in which one end on the short side protrudes toward the sill groove 12 (a shape in which a tip portion is bent into the sill groove 12). Formed. As shown in FIG. 3, a predetermined gap (space) S is provided between the distal end portion (projecting portion) bent in the sill groove 12 and the guide portion 2 b of the door guide shoe 2. As described above, since the fixing bracket 4 is provided along the sill groove 12, a similar predetermined gap S is also provided on the other short side facing the short side having the protruding portion. The clearance S is a position adjustment operation performed when the elevator sill groove cleaning device 3 is fixed to the door panel 1 together with the door guide shoe 2, and is located behind the elevator sill groove cleaning device 3 (door panel 1 side). It is possible to easily adjust the position of the door guide shoe 2 positioned at the position. More specifically, since the clearance S is provided, a work space for performing the position adjustment work is secured, so that the worker can easily perform the position adjustment work.

  As shown in FIG. 1, a brush fixing portion 5 is provided at the distal end portion of the fixing bracket 4 bent in the sill groove 12. That is, the brush fixing portion 5 is provided in the threshold groove 12. As described above, the brush fixing portion 5 is provided in the sill groove 12, whereby the possibility that the cleaning brush 6 interferes with the door panel 1 can be reduced.

  The brush fixing portion 5 is formed in a U-shape (U-shape) whose opening is opposed to the sill groove 12, and the cleaning brush 6 is sandwiched and fixed by the U-shaped opening. In this U-shaped brush fixing portion 5, as shown in FIGS. 4 and 5, one surface 5b of two opposing surfaces (two surfaces sandwiching the cleaning brush 6) 5a, 5b is a cleaning brush. When 6 is fixed, it is caulked in an arc shape. Specifically, as shown in FIG. 6, the surface 5 b is caulked so that both ends of the caulking ridge line A are strongly squeezed to form an arc as a whole. In addition, in order to mention later the advantage acquired by making the surface 5b circular arc shape, the detailed description is abbreviate | omitted here.

  In the present embodiment, for convenience of explanation, the fixing bracket 4 and the brush fixing portion 5 are described separately, but actually, the fixing bracket 4 and the brush fixing portion 5 are integrally formed.

  Next, the cleaning brush 6 included in the elevator sill groove cleaning device 3 will be described with reference to FIG. FIG. 7 is a view showing the cleaning brush 6 before being fixed to the brush fixing portion 5. As shown in FIG. 7, the cleaning brush 6 includes a channel material 6a and a number of bristle materials 6b. Each bristle member 6b is folded inside the channel member 6a on the basis of a core wire (in other words, the center of the surface facing the opening of the channel member 6a among the three surfaces of the U-shaped channel member 6a). The channel member 6a is fixed by caulking both side surfaces (in other words, two opposing surfaces of the three surfaces of the U-shaped channel member 6a).

  In addition, the both ends of the both side surfaces of the channel material 6a are closed. The closing process is a process in which both end portions of both side surfaces of the channel material 6a are squeezed more strongly than the central portions of both side surfaces, and both end portions are closed. By this processing, the hair material 6b becomes the channel material 6a. Can be prevented from falling off. As described above, since both ends of both side surfaces of the channel material 6a are closed, both side surfaces of the channel material 6a are arcuate.

  Here, with reference to FIG. 8, the advantage obtained by caulking the brush fixing portion 5 in an arc shape will be described. FIG. 8 is a view of the cleaning brush 6 as viewed from the sill groove side. In FIG. 8, it is assumed that the greater the caulking force is, the longer the length of the arrow indicating the caulking force is. Similarly, in FIG. 8, it is assumed that the larger the opening, the longer the length of the arrow indicating the opening.

  When the cleaning brush 6 is fixed to the brush fixing portion 5, for example, as shown in FIG. 8A, if the brush fixing portion 5 is not fixed by caulking in a circular arc shape, the both sides of the cleaning brush 6 are uniform. The caulking force B acts. As described above, both ends of both side surfaces of the channel material 6a of the cleaning brush 6 are closed, and both side surfaces of the channel material 6a are arcuate, so that a uniform caulking force B acts. As shown in FIG. 8A, the opening C is generated at both end portions of both side surfaces of the channel material 6a. In particular, the brush fixing portion 5 and the cleaning brush 6 cannot be made very large for the convenience of being provided in the sill groove 12, so that a large opening C is generated when the uniform caulking force B acts. That is, the advantage obtained by closing the both ends of the both side surfaces of the channel material 6a cannot be obtained, and the bristle material 6b is likely to fall out of the channel material 6a.

  On the other hand, when the cleaning brush 6 is fixed to the brush fixing portion 5, when the brush fixing portion 5 is fixed by caulking in an arc shape, as shown in FIG. The caulking force B can be prevented from acting, and the opening C generated at both ends of the both side surfaces of the channel material 6a can be reduced. That is, it is possible to prevent the bristle material 6b from falling off the channel material 6a.

  In addition, although this embodiment demonstrated the case where the brush fixing part 5 was crimped in circular arc shape and the cleaning brush 6 was fixed, it is not limited to this, The brush fixing part 5 may be a slot type. According to this, it becomes possible to replace the cleaning brush 6 alone.

  According to the embodiment described above, the elevator sill groove cleaning device 3 uses the screw hole 1a and the mounting hole 2c that are generally formed in the door panel 1 and the door guide shoe 2 together with the door guide shoe 2. Since it can be installed if it is fastened together with the door panel 1, it can be widely applied to existing elevators without requiring special parts.

  Moreover, since the elevator sill groove cleaning device 3 according to the present embodiment has the key-shaped fixing metal fitting 4 whose one end on the short side protrudes toward the silling groove 12, A predetermined gap S is provided between the door guide shoe 2 and the guide portion 2b. According to this, since the predetermined gap S can be a work space where the worker works when attaching the elevator sill groove cleaning device 3, the worker can easily attach the elevator sill groove cleaning device 3.

  Furthermore, since the elevator sill groove cleaning device 3 according to the present embodiment has the brush fixing part 5 that is caulked in an arc shape, the closing process applied to the cleaning brush 6 does not open, and the cleaning brush 6 Can be prevented from falling off.

  In addition, as shown in FIG. 9, the caulking allowance 5c may be provided in the both ends of the brush fixing | fixed part 5. As shown in FIG. The caulking allowance 5c is a surplus space used when caulking the brush fixing portion 5. As shown in FIG. 9B, by providing the caulking allowance 5c at both ends of the brush fixing portion 5, as shown in FIG. 9A, the caulking allowance 5c is provided at both ends of the brush fixing portion 5. Compared with the case where it is not, the workability (caulking workability) when the brush fixing part 5 is caulked in an arc shape can be improved.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
