DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool for mounting a cleaning cloth made of a chemical fiber, a natural fiber or the like on a base portion for cleaning.

[0002]

2. Description of the Related Art Conventionally, in wiping, a cleaning surface (including a sheet) is directly wiped with a hand to wipe a cleaning surface. For example, when wiping a window glass of a house or a shield glass of an automobile, the cleaning cloth is widely spread with a palm. And evenly wipe it. Also,
If it is a hand, even the uneven surface can be wiped with a cleaning cloth attached to some extent. However, there is a problem in that cleaning with the cleaning cloth held by hand causes a partial wiping residue between fingers of the hand and a problem of insufficient following of the curved surface due to insufficient follow-up. For this reason, there is a cleaning tool in which an elastic projection is provided on the entire bottom surface of the base (holding plate), a cleaning cloth is mounted on the base, and the cleaning cloth is pressed against the surface to be cleaned with a large number of irregularities to clean the surface. -150663, JP-A-9-14065

[0003]

In the above prior art,
When cleaning screen doors and windows, if you try to remove persistent dirt attached to the surface, you will have to press with the handle or handle, but you can wipe off the dirt where the cleaning cloth is pressed by the projection on the surface to be cleaned However, there has been a problem that the cleaning cloth does not hit the surface to be cleaned, leaving a portion to be wiped off, so that it is difficult to perform a sufficient and satisfactory cleaning. on the other hand,
There is a cleaning tool that can press a sheet flat by attaching a sheet-like material for removing dirt to the lower surface of an elastic plate-like base portion (Japanese Patent Application Laid-Open No. 10-323313, Utility Model Registration No. 3027503). However, if the entire bottom surface of the base portion is flattened as in this cleaning tool, there is a disadvantage that poor conformability to the uneven surface remains.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a cleaning cloth which can press a cleaning cloth on a surface to be cleaned without a gap when cleaning the surface to be cleaned, and has an uneven surface. However, it is an object of the present invention to provide a cleaning tool which can sufficiently follow the surface of the surface to be cleaned to easily remove persistent dirt and the like, and can easily and sufficiently clean the surface to be cleaned without leaving wiping all over.

[0005]

The present invention has the following arrangement to achieve the above object. According to the present invention, in a cleaning tool for attaching a cleaning cloth to a bottom surface of a base portion, a first elastic body having an exposed surface is laid on at least a part of the bottom surface of the base portion, and an elastic material is provided on the remaining portion. Second with protrusion
The cleaning tool is characterized in that a cleaning cloth is attached so as to cover the bottom surface of the base portion on which both elastic bodies are laid. In the present invention, a handle is provided on the upper surface of the base portion, the first elastic body is laid including the central portion of the base portion, and the central portion of the elastic body protrudes more slowly than the peripheral portion. It is preferable to have a chevron shape.

According to the present invention, the base has a first elastic body having a flat exposed surface at least in part and an elastic projection in the remaining part, so that the first elastic body has a flat surface. As a result, the cleaning cloth can be pressed onto the surface to be cleaned at the time of cleaning without any gap in a planar manner, and at the same time, the cleaning cloth can be pressed sufficiently following the surface to be cleaned by pressing with the second elastic body having irregularities. It is easy to remove persistent dirt and the like on the surface of the cleaning surface, and the surface to be cleaned can be easily and sufficiently cleaned without wiping all over. In addition, a handle is provided on the upper surface of the base to make it easier to press the bottom of the base strongly.
If the elastic body is provided so as to include the central portion of the base portion and the central portion of the elastic body is formed in a chevron shape projecting gently from the peripheral portion, when it is desired to press the cleaning cloth particularly strongly, the cleaning cloth is formed at the central portion. Can be pressed sufficiently and easily, and persistent dirt can be reliably wiped off.

The following are considered to be appropriate as the usable length, density, and elasticity range of the elastic projection in the cleaning tool of the present invention. Length: 3 to 20 mm (preferably, 5 to 15 mm). If the length is outside the range, the elasticity (flexibility) of the projections is small and it is difficult to wipe when the length is outside the range. It is. Density: 300 to 3000 lines / 100 cm ² (preferably 500 to 2000 lines / 100 cm ² ). When the density is set in this range, when the density is out of the range, the wiping streaks (remains after wiping the dirt) is remarkably increased, while when the density is out of the range, the adjacent protrusions collide with each other and are hardly bent. Because. Elasticity: 0.1-50kg (preferably 1-20kg)
[JIS-compliant 25% hardness measurement adapter diameter 40m
m]. If the elasticity is set within this range, if the elasticity is low outside the range, there is no response, poor cleaning performance (power escapes),
On the other hand, if it is high outside the range, it does not bend and there is no feeling of wiping (a feeling of slipping). Materials usable for the elastic projections: general resins such as vinyl chloride resin, PP (polypropylene) and PE (polyethylene), or elastomers (rubber elastic materials) (preferably EVA)
(Ethylene-vinyl acetate copolymer)).
