DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool and a cleaning sheet to which a cleaning sheet is attached and which is used for wiping, sweeping, etc.

[0002]

2. Description of the Related Art Conventionally, a cleaning tool to be used for cleaning by attaching a cleaning sheet (cleaning sheet) is disclosed in
As described in Japanese Patent No. 276957, a scraping portion is provided around a mounting substrate, in which a sheet-like urethane foam having a restoring force is folded in two and attached, and the whole is formed into a thick plate shape. There is one that attaches a cleaning sheet to the surface to clean it. Also, JP-A-7-8
As disclosed in Japanese Patent Application Laid-Open No. 434 and Japanese Patent Application Laid-Open No. 7-303589, an elastic material is used as a member for attaching a mop or a cleaning sheet.

[0003]

However, even when cleaning is performed with the above-mentioned conventional cleaning tool, the cleaning sheet cannot be pressed against the surface to be cleaned near the base, so that only a part of the cleaning sheet contacts the cleaning surface. I won't hit you. For this reason, there are many unused portions of the cleaning sheet and waste is increased, and it is necessary to immediately replace the cleaning sheet. Also, when the cleaning sheet is attached to the cleaning section and the cleaning sheet is pressed against the linear corners of the cleaning section, the cleaning sheet removes dust and dirt linearly corresponding to the corners. The wiping becomes worse immediately because of the small area. For this reason, it is necessary to frequently change the mounting position of the cleaning sheet or replace the cleaning sheet itself.
There are many unused portions of the cleaning sheet, which leads to waste, and it is necessary to replace the cleaning sheet immediately, which is troublesome. In addition, various methods of fixing a sheet have been proposed for a cleaning tool to which a cleaning sheet is attached. However, the sheet may not be sufficiently used because the sheet may come off halfway. For example, in a type in which a slit is formed in a cleaning section of a sheet and the sheet is inserted (see Japanese Utility Model Application Laid-Open No.
No. 5061), a force is applied due to friction of the sheet during cleaning, and the sheet sometimes comes off. In the case of a type in which a sheet is inserted by using a sheet mounting device (Japanese Utility Model Laid-Open No. 6-62960), the problem of being detached is reduced, but there is a problem such as contact with a finger. Further, in the case of a type in which a sheet is sandwiched by using a sheet mounting device, the problem of being detached is reduced, but mounting is troublesome, and in the case of a spring type, mounting requires force on fingers.

[0004] It is inconvenient that only the pressing of the cleaning sheet cannot sweep or remove the dust on the floor. Further, in the technique described in the above-mentioned publication, as shown in FIG. 6 of JP-A-7-303589, a mounting member made of an elastic material is entirely bent by pressing, but if the elastic force of the mounting member is strong, a user having a weak force is required. However, if the elasticity of the mounting member is weakened, the pressing force of the sheet is weakened, and the wiping and cleaning cannot be performed properly. Moreover, since the attachment member is forcibly bent as a whole, the durability may be low.

The present invention has been made in view of the above problems, and has as its object to provide an easy-to-use cleaning tool and a cleaning sheet that can use the cleaning sheet without waste and reduce the frequency of replacement. And

[0006]

Various modifications can be made, such as an arrow shape with a widened portion. Also,
The tip may be rounded without ridges, as shown by the two-dot chain line.

The cleaning section 12 can be made of an elastic material (urethane foam, rubber, elastomer, foamed EVA, foamed polyethylene, etc.). In addition, the seat mounting section 1
6 and the bent portion 22 may be integrally formed of the same material, or may be integrally formed by fixing separate members.

As shown in FIG. 2, the sheet 18 is attached to the cleaning section 12 by winding the sheet 18 around the mounting section 16 and fixing the sheet 18 by an appropriate method. As a mounting method, as shown in FIG. 3, one or more sheet fastening portions 24 having one or more sharp projections 26 are provided on the cleaning portion 12 or the base portion 10, and the sheet 18 is fastened by the fastening portions 24. Fix it.

The seat fastening portions 24 of the embodiment are provided at four locations on the shoulder of the mounting portion, and each fastening portion 24 cuts one side of a substantially rectangular (other shape may be used) plate to form a concave portion 28. As shown in (e) and (d), two or more projections 26 are formed so as to project toward the recess 28. The concave portion 28 is large enough to receive a finger, and the fastening portion 24 is fixed to the cleaning portion 12 except for a portion having the projection 26. Also, in particular,
