Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cleaning device, and more particularly, to a device for automatically cleaning a rail surface when a door is opened and closed by connecting at least one clean brush device to a hanging member of each door of the automatic door. The present invention relates to an automatic cleaning device that performs the following.

[0002]

2. Description of the Related Art Conventionally, an automatic door apparatus has a rail, a belt pulley set, a drive motor, and the like provided in one frame wheel, and a hanging member connected to the top end of the door of the automatic door. And the roll is placed over the rail surface, and the door is opened and closed by automatic operation of the drive motor.

[0003]

In use, however, dust such as dust and sweat dust in the air, and wear and bending of the belt and belt pulley during driving of the belt and the belt pulley are all scattered on the rail surface. drop down. If the lifting tool roll is subjected to an expansion pressure, the roll is more easily gathered on the ring surface and the rail surface, and sticks to form a convex point, thereby destroying the roundness of the roll. In addition, the flatness on the rail surface is destroyed, thereby causing a phenomenon in which the roll of the hanging tool jumps when sliding on the rail, thereby generating annoying noise. Further, there is a problem that the roll and the rail are broken to make the sliding movement of the opening and closing of the door worse.

[0004] In view of the above problems, it is difficult for a user to periodically perform cleaning and maintenance by himself. The reason is that most users do not know the structure of the automatic door, so they do not know how to clean it. Still and very cumbersome, it is fundamentally impossible for a user to request cleaning himself on a regular basis. By the way, the conventional automatic door device has a problem that the user cleans himself by himself as described above.

It is an object of the present invention to provide an automatic cleaning device capable of smoothing the sliding movement of an automatic door.

[0006]

According to the automatic cleaning device of the present invention, the cleaning device includes one clean brush device, and one brush head is linked to the hanging member of each door of the automatic door. When the brush bristles are in contact with the rail surface of the automatic door in opposition and the doors are opened and tightened, the cleansing brush device automatically cleans dirt and dust on the rail surface at the same time, Dust accumulates on the roll and rail surfaces of the hanger and prevents the dirt from sticking to smooth the sliding movement of the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automatic cleaning apparatus according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, at least one clean brush device 2 is provided on the hanger 1 at the top end of the door D of the automatic door, and the brush bristles 221 of the clean brush device 2 are provided in one frame box 3. , And the dust and dirt on the rail surface 31 are reciprocated and wiped off as the door D opens and closes. This keeps the door D of the door sliding smoothly.

A hanging member 1 attached to the top end of the door D of the door
Includes at least the following: One bottom plate 11 connects the top ends of the doors D with the bottom plate 11. Further, one vertical plate portion 12 is connected to the bottom plate portion 11, and one roll 121 is pivoted from one side to the outside so as to extend over one rail surface 31 and slide. Move. The above-mentioned hanging device 1 is a known component, and thus description thereof will be omitted. Since the cleansing brush device 2 can be modified and attached to other types of hanging devices, it is possible to form an automatic cleaning device for rails of an automatic door with the present invention within the scope of the drawings and the present invention. Add emphasis.

The clean brush device 2 can include the following. A single mounting plate 21, the bottom end of which forms one connecting portion 211, penetrates through the fixing hole 211 a, and
0, and the top of the connecting portion 211 is curved to form one hooking portion 212 and one hooking hole 2
12a. One brush head 22, the brush head 22 is connected to the mounting plate 21, and the bottom end is provided with a bristle bristles 221;
Further, the brush head 22 does not have a top end, but forms a hooking edge 222, and is fitted and fixed in the hooking hole 212a of the hooking portion. Further, one brush bristle protection cover 23 is connected to the brush head 22, and both sides of the cover 23 respectively extend a single stop plate 231 downward, and the front and rear of the bottom end of the brush head 22 are provided. When the brush bristles 221 wipe and wipe the dirt on the rail surface 31, they are not bent or deformed excessively.

The automatic cleaning device for an automatic door rail according to the present embodiment is provided with at least one clean brush device 2 in front of the roll 121 of the hanging device 1, that is, in front of the opening direction of the roll.
When the automatic door opens the door, the brush bristles 221 of the clean brush device 2 first clean dirt on the rail surface 31, and the rail surface 3 on which the rear roll 121 goes.
Roller 121 and rail surface 31 are free from sticking, dust, and dust due to the expansion pressure because 1 is in a clean state and there is no dust and dust, so that automatic door opening and closing can be ensured smoothly and no noise is generated. . Naturally, even if this embodiment is modified and one clean brush device 2 is provided on each of the hanging members 1 on both sides of the roll 121, the rail surface 31 reciprocates along with the opening and closing of the automatic door. Since the printing is wiped off, it is possible to apply the present embodiment in a modified form.

As shown in FIG. 1, the clean brush device 2 of this embodiment is assembled by fitting the brush bristle protection cover 23, which has been previously formed in a circular shape, above the brush head 22 and straddling the brush head. With this, the stopper plates 231 on both sides are fixed to the front and rear ends of the brush head 22, and the brush head 22 is wrapped around the brush bristles 221 to surround the brush head 22 at the top edge 22.
2, the screw hole 223 at the top end of the brush head 22 is screwed through the through hole 212b of the hook portion 212 with the screw 20a. The brush head 22 and the brush bristle protection cover 23 are
Fasten on top of 1. In this manner, the mounting plate 21 is fixed on the hanging tool 1 by passing the fixing holes 211a of the connecting portion 211 of the mounting plate 21 with the screws 210, and each of the brush bristles 221 of the brush head 22 is attached to the frame box 3 And slides along with the hanging tool 1 to wipe off dirt such as dust and falling dust on the rail surface 31.

The fixing hole 211a, through which the connecting portion 211 of the mounting plate 21 of the embodiment described above penetrates, is one long tank hole, and is used for adjusting the upper and lower movements by the installer. It is used for adjusting the pressure between the brush bristles 221 at the bottom end of the head 22 and the rail surface 31. When the amount of air debris dropped from the workplace is relatively large, the brush bristles 221 of the clean brush device 2 always apply a relatively large wiping pressure to the rail surface 31 as shown in FIG. One spring 24 is provided between the plate 21 and the hanging device 1, and a first spring end 241 of the spring 24 is connected to the frame 21 and a second spring end 242 is provided on the hanging device 1. Attached to the thrust pin 13 of
Each fixing hole 211a of the connecting portion 211 of the mounting plate is slidably fitted out of each screw 210 so as to move, and the brush bristles 221 at the bottom end of the brush head 22 to which the mounting plate 21 is connected are connected to the spring 2
The rail surface 31 is elastically pressed by the interlocking operation of the rails 4 to enhance the wiping effect.

In the present invention, the brush head and the bristle protection cover or the frame can be formed integrally. In the present invention, when the door is opened and closed, the clean brush device also wipes the rail surface in a reciprocating manner to keep the rail surface clean and to automatically make the sliding motion of each door of the automatic door smooth. Besides, regular maintenance can be reduced.
