Abstract

PURPOSE:To more surely and easily remove the dust in a sill by providing a rotary brush body with the brush in a contact state with the bottom of the sill rolled by moving its handle and sweeping the dust in the sill into a receiving box. CONSTITUTION:When the dust 14 in a sill 12a is removed, a receiving box 23 and a brush 24a are inserted into the sill 12a, a roller 25 is brought into contact with the upper edges on both sides of the sill, and a handle 21 is moved along the sill 12a. At this time, the length of the brush is set so that its tip is brought into contact with the bottom of the sill 12a, and the brush body 24 and the roller 25 are rolled in the same direction. When the brush body 24 is rotated in this way, the dust 14 is swept into the box 23 by the brush 24a. Consequently, the dust 14 is removed only by moving the handle 21 along the sill 12a with no need for a quick action.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sill groove cleaning tool for removing dust such as pebbles in a sill groove of an elevator door device or the like.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing an example of an elevator. In the figure, 1 is a hoistway, 2 is a machine room provided above the hoistway 1, 3 is a sheave of a hoisting machine installed in the machine room 2, and 4 is a warp installed in the machine room 2. A car, 5 is a rope wound around the sheave 3 and the deflecting wheel 4, 6 is a car suspended at one end of the rope 5, and 7 is a counterweight suspended at the other end of the rope 5. .

8 is a car door that opens and closes the entrance and exit of the car 6,
9 is provided in the car 6, a car-side sill that guides the lower end of the car door 8, 10 is a landing hall, 11 is a landing door that opens and closes the entrance and exit of the hall 10, 12 is provided on the floor of the landing 10, It is a hall-side sill that guides the lower end of the door 11 of the hall.

FIG. 4 is an enlarged sectional view showing a portion IV in FIG. In the figure, door legs 8a and 11a are attached to the lower end of the car door 8 and the lower end of the landing door 11, respectively. The car side and landing side thresholds 9 and 12 are
Sill groove 9a into which the foot 8a, 11a of the door is inserted,
12a is provided along the opening / closing direction.

In the elevator as described above, dust such as small stones may enter the threshold grooves 9a and 12a when passengers enter and leave the car 6. This kind of dust is the threshold ditch 9
Since it may interfere with the opening and closing of the door 8 of the car and the door 11 of the landing if it accumulates in a and 12a, it has been conventionally necessary to use the structure shown in FIGS.
As shown in, the dust 14 was removed using the sill groove cleaning tool 13. The conventional sill groove cleaning tool 13 is a scoop-shaped tool, and by inserting this into the sill grooves 9a and 12a and moving it quickly, the dust 1 is removed at the tip thereof.
It is designed to scoop four.

[0006]

In the conventional sill groove cleaning tool 13 configured as described above, since the entire shape is a mere scoop shape, the sill grooves 9a, 12a.
There is a problem that the dust 14 cannot be easily removed because it needs to be quickly moved inside.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a sill groove cleaning tool capable of more reliably and easily removing dust in the sill groove. And

[0008]

According to a first aspect of the present invention, there is provided a sill groove cleaning tool comprising a handle, a receiving box attached to the handle and inserted into the sill groove, and a rotatably attached to the handle. In addition to having a brush on the outer periphery,
A rotating brush body that rolls by moving the handle along the sill groove in a state where the brush is in contact with the bottom of the sill groove and sweeps the dust in the sill groove into the box.

The sill groove cleaning tool according to the invention of claim 2 is
The handle is provided with rollers that roll along the edges on both sides of the sill groove so as to be rotatable.

[0010]

In the first aspect of the invention, the dust in the sill groove is picked up by the rotation of the rotary brush body and put into the receiving box.

According to the second aspect of the present invention, by providing the roller, the handle can be moved smoothly, and
There is no need to adjust the insertion amount of the rotating brush body into the threshold groove.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a sectional view showing a state where a sill groove is being cleaned using a sill groove cleaning tool according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line II-II of FIG. 3 to 6 are designated by the same reference numerals, and the description thereof will be omitted.

In the figure, 21 is a frame portion 2 at the lower end.
A bar-shaped handle 1a is provided, 22 is a frame portion 21a
The shafts and 23 provided on the shaft 22 are rotatably attached to the shaft 22 and accommodate the dust 14 therein.
A convex portion 23a for preventing the contained dust 14 from spilling out is provided in the opening of the. 24 is a shaft 22
Is a rotating brush body that is rotatably attached to the middle part of the
A large number of brushes 24 a are planted in the outer peripheral portion of the No. 4. Reference numeral 25 denotes a pair of rollers rotatably attached to the shaft 22 on both sides of the rotary brush body 24.

Next, the operation will be described. Threshold groove 12
When removing the dust 14 in the a, the receiving box 23 and the brush 24a are inserted into the sill groove 12a, and the roller 2
5 on the edges of both sides of the threshold groove 12a, and
Is moved along the threshold groove 12a. At this time, the brush 24a is set to have a length such that its tip comes into contact with the bottom of the threshold groove 12a, whereby the rotating brush body 24 rolls in the same direction as the roller 25. In this way, when the rotating brush body 24 rotates, the dust 14 is swept into the receiving box 23 by the brush 24a.

According to such a sill groove cleaning tool, the sill groove 12 is held by the handle 21 without requiring a particularly quick operation.
The dust 14 can be removed more reliably and easily by simply moving it along a. Further, since the roller 25 is provided, the movement of the handle 21 becomes smooth, and it is not necessary to adjust the insertion amount of the rotary brush body 24 into the threshold groove 12a.

1 and 2, the sill groove 12a of the hall-side sill 12 is cleaned, but the sill groove 9a on the car side is shown.
Is also the same. Further, although the elevator is shown in the above embodiment, it is needless to say that the sill groove cleaning tool of the present invention can be used for cleaning the sill groove of another door device.

[0017]

As described above, according to the sill groove cleaning tool of the invention of claim 1, the rotary brush body which rolls in the sill groove by moving the handle along the sill groove is used to move the sill inside the sill groove. Since I tried to sweep the garbage into the box,
It is possible to remove dust in the threshold groove more reliably and easily.

Further, the sill groove cleaning tool of the invention of claim 2 is the same as the invention of claim 1 in that the handle is provided with rollers which roll along the edges on both sides of the sill groove so as to be rotatable. In addition to the above effect, the handle can be moved smoothly, and the adjustment of the insertion amount of the rotating brush body into the sill groove can be dispensed with, and the operability can be improved.
