Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cleaning tool.

[0002]

2. Description of the Related Art As a cleaning tool, as described in Japanese Patent Application Laid-Open No. 1-262827, a scooping member is rotatably supported on a frame, and a dust removing part is supported on the rear part of the scooping member on the frame. There is something.

[0003]

The dust collector does not swing up and down with respect to the frame independently of the scooping member. For this reason, when the cleaning tool is used to clean a carpet with long fluff, as the dust collector slides on the upper surface of the carpet, the scraping body also slides on the upper surface of the carpet. It is not possible to scrape up the dirt buried in the floor with the body. When the scraper is pushed by the user with a stronger force so that the scraper goes under the hair of the carpet, the dust collecting part is strongly pressed by the carpet, resulting in a large resistance to the forward movement, which deteriorates the operability.

An object of the present invention is to allow a scraping body to smoothly scrape dust even when it is buried in the hairs of a long-haired carpet while smoothly sliding the dust collecting part on the floor surface. Especially.

The cleaning tool 10 can move backward as well as forward. The dust collecting part 23 flips up the tail end of the bottom surface part 23A in a rounded shape, and prevents the tail end from being caught on the floor surface when moving backward.

According to the cleaning tool 10 described above, the carpet is scraped up by the scooping member 16, and the dust is then adsorbed and captured by the adhesive roll 21. Adhesive roll 21
Does not directly contact the carpet, so that it does not damage the carpet, it is possible to capture dust that has sunk in the deep portion of the fibers of the carpet, and the durability of the adhesive performance of the adhesive roll 21 is improved.

Also in the flooring, as in the case of the carpet, since the adhesive roll 21 does not directly contact the flooring, the adhesive roll 21 is not strongly adhered to the flooring and fixed.

The structure for supporting the dust removing portion 23 by the frame 15 will be described below. (Figs. 1-3)

The dust collecting portion 23 is supported on the frame 15 so as to be vertically swingable independently of the scraping body 16, and the dust receiving portion 23C of the dust collecting portion 23 is supported so as to be openable from the frame 15.

Specifically, as shown in FIG. 1, the dust removing portion 23
The front end on the side close to the scraping body 16 in the swinging part 40
(Pin 41 provided on both front end side surfaces of dust removing portion 23 is vertically movably engaged in elongated holes 42 provided on both side walls of frame 15) and is swingably supported on frame 15. . In addition, the hole 51 of the engagement / disengagement portion 50 provided at the rear end of the dust collecting portion 23 on the side far from the scraping body 16 is provided in the frame 15
The hole 51 is detached from the disengageable pin 52 so that the rear end of the dust removing part 23 can be released from the frame 15. With the hole 51 of the dust removing part 23 engaged with the detachable pin 52 of the frame 15, the detachable pin 52 is used as the central axis of the swing of the dust removing part 23, and the hole 51 of the dust removing part 23 is used as the frame. With the pin 15 detached from the detachable pin 52, the swinging part 40 serves as the opening central axis of the dust removing part 23.

Further, as shown in FIGS. 2 and 3, the dust collecting portion 23
At both ends of the front edge 23D, warped plate-shaped guide shoes 23E that warp forward and upward with respect to the floor surface are provided. Here, the guide shoe 23E is in surface contact with the floor surface and does not have the rake face portion 23B. A portion of the front edge 23D of the dust collecting portion 23, which is sandwiched by the guide shoes 23E at both ends, forms an edge (lowermost end portion) on the floor surface side of the rake surface portion 23B and slides on the floor surface of the flooring or tatami mat without any gap. .

Therefore, the cleaning tool 10 as described above has the following effects. When the cleaning tool 10 is used on a carpet with long hair,
Even if the scraping body 16 is moved forward while pressing the scraping body 16 against the carpet's hair so that the scraping body 16 dive into the carpet's hair and scrapes up dust, the dust collecting part 23 guides both ends. The operability is good because the shoe 23E floats on the hair of the carpet and the front edge 23D of the dust removing part 23 does not pierce into the hair of the carpet to resist the forward movement, and the shoe 23E can smoothly move forward. .

The dust removing section 23 has guide shoes 23E which are warped up against the floor surface only at both ends of the front edge 23D.
The part of the front edge 23D sandwiched by the guide shoes 23E contacts the floor surface without any gap. Therefore, even when cleaning flooring or tatami other than carpet, the front edge 23D of the dust removing portion 23 contacts the floor surface without any gap, and the dust scraped up by the scraping portion 16A of the scraping body 16 escapes rearward along the floor surface. You can catch all that trash without having to.

The dust scraped up by the scraping member 16 can be adsorbed and captured by the adhesive roll 21. At this time, the contact rotator 18 comes into contact with the adhesive roll 21 to surely rotate the adhesive roll 21. Therefore, the pressure-sensitive adhesive surface of the pressure-sensitive adhesive roll 21 in contact with the scraping body 16 can be uniformly and efficiently utilized by rotating the scraping body 16.
The new suction surface of the pressure-sensitive adhesive roll 21 can surely suck and collect the dust scraped up by the suction roller.

Since the adhesive roll 21 is laid over the scraping body 16 and the contact rotary body 18, the adhesive roll 21 of any size, large or small, can be loaded into the cleaning tool 10. Therefore, the outer diameter of the adhesive roll 21 can be manufactured with a degree of freedom, and the adhesive roll 21 having an appropriate outer diameter can be selected according to the floor condition.

Both the dust scraped up by the scraping body 16 from the deep portion of the fiber of the carpet and the dust scraped backward from the hard flat surface of the flooring are surely scooped up by the dust collecting part 23 at the rear part of the scraping body 21. Adhesive roll 21
Guided in the direction of, the dust collection performance can be improved.

The pressure-sensitive adhesive roll used in the present invention may be one in which a tubular sheet is detachably covered on the core roll. At this time, the original shape of the tubular sheet is a sheet-type envelope sheet, and a large number of envelope sheets can be stacked and stored.

Further, in the present invention, the scraping body is not limited to the brush, but may be a sponge, a rubber blade, an elastomer, an elastic protrusion or the like.

Further, in the present invention, the contact rotating body is not limited to the roll body, but may be a tire or the like.

In the present invention, the floor surface is a tatami mat, a flooring, a carpet or the like, and has a remarkable and unique effect particularly on the carpet.
