Abstract

PROBLEM TO BE SOLVED: To improve the stain removing property and usability of sweeping equipment when it is used without applying an excessive force to the sweeping equipment by fixing the end portion of a handle to the sweeping portion, and making the portion near the sweeping portion of the handle flexible and other portion rigid. SOLUTION: The portion 12b near the sweeping portion of the handle 12 of sweeping equipment is formed of an elastic material having flexibility such as rubber, elastomer, or a metal spring, and the other portion 12c is composed of a rigid body such as a hard plastic and aluminum. The sweeping portion 10 is flat in one side 10a and the flexure of the handle 12 is set to that the plane of the sweeping portion 10 may touch an object of sweeping entirely. And when load is applied to the part roughly 20 cm away from the head of the handle 12, the formula 0.10<=B/A<=100 should be established (wherein, A is a difference (cm) in position where before and after load is applied, and B is load (g)).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning tool having a cleaning portion and a handle.

[0002]

2. Description of the Related Art Conventionally, to remove dirt such as dust (dust) adhered to furniture, household appliances, lighting equipment, etc.
It is a collection of cloths engraved in strips at the tip of a handle called hatsuki, which is made suitable for removing dust by hitting the surface to be cleaned and cleaning furniture, appliances and lighting equipment. A method of wiping dust with a small-sized plate-shaped mop to which a nonwoven cloth is attached is known.

[0003]

However, the hitter and small-sized plate-shaped mop conventionally used have an excellent function of removing dust, but their usability has not been sufficiently considered.

That is, since the handle of the cleaning tool is straight and the plate of the cleaning surface is flat, the cleaning surface of the cleaning tool partially acts on the surface to be cleaned at the time of cleaning. And trying to solve the problem by making the cleaning surface flat.

[0005] However, in such a case, since excessive force is applied to the cleaning tool, the cleaning tool is not only partially consumed but also cracks on the surface to be cleaned, especially on cracked objects such as lighting fixtures. Work efficiency was not improved due to the consideration that there was no work. In particular, in the case of a cleaning tool equipped with a nonwoven cloth, the cleaning surface partially acts on the surface to be cleaned. There was a problem of becoming.

As for the cleaning tool, there has been proposed a cleaning tool provided with a flexible cleaning cloth mounting head at the tip of a handle (see Japanese Patent Application Laid-Open No. 9-38009). However, in this cleaning tool, since the flexible head hits the target surface in a bent state, the partial use of the cleaning surface itself cannot be improved. It has to be replaced, and the above problems could not be solved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is excellent in removing dirt without exerting excessive force on the cleaning tool, and has improved usability when using the cleaning tool. An object is to provide an excellent cleaning tool.

[0008]

The present invention has the following configuration to achieve the above object. The invention of claim 1 is
A cleaning portion having a cleaning portion and a handle, wherein the tip portion is fixed to the cleaning portion, and the cleaning portion side portion of the handle has flexibility and the other portion has rigidity. It is a tool.

According to a second aspect of the present invention, when a load is applied to a position approximately 20 cm from the tip of the handle, the formula 0.1 ≦ B / A ≦ 100 (where A: the before and after the load is applied) 2. The cleaning tool according to claim 1, wherein a difference (cm) between the positions of the portions and B: a magnitude (g) of the load are satisfied.

According to the first aspect of the present invention, in the cleaning tool, the tip of the handle is fixed to the cleaning portion, but the portion of the handle on the cleaning portion side has flexibility and the other portions have rigidity. Therefore, only the cleaning section side portion is bent as necessary. Therefore, when the cleaning unit is pressed against the uneven surface to be cleaned, such as an umbrella of a lighting fixture, with a certain amount of force (of course, a force that does not cause a problem to the object surface) and wiped, the direction of the cleaning surface of the cleaning unit becomes uneven. The cleaning portion side portion of the handle is bent so as to appropriately cope with the problem, and the cleaning surface can be appropriately responded to the target surface without applying unnecessary force. Therefore, even the inside of the unevenness can be reliably cleaned. In addition, since the cleaning portion side of the handle has flexibility, the contact of the cleaning portion with the target surface is soft, so that dirt can be thoroughly removed from cracks such as lighting fixtures without using much care. Can be removed. Therefore, it is excellent in usability as well as dirt removal.

In addition, since the handle is bent at the cleaning section side, only the cleaning section side of the handle is bent at the back side which cannot be normally reached when it is inserted between furniture and a wall, so that it can be adapted to the target surface. The cleaning efficiency is improved, and the dirt removability is improved.

According to the second aspect of the present invention, when a load is applied to a position approximately 20 cm from the tip of the handle, the formula 0.1 ≦ B / A ≦ 100 (→ particularly preferably 3 ≦ B /
A ≦ 55) (However, A: difference (cm) between the positions before and after the load is applied, and B: magnitude (g) of the load). The efficiency of the cleaning unit is high and the usability is excellent.

That is, as a result of the test, when B / A> 100, the bending of the handle was not felt, and the workability on the vertical surface was reduced. Further, when B / A <0.1, the cleaning surface could not be appropriately made to correspond to the target surface, and the force applied at hand did not well transfer to the cleaning surface, so that the workability was also lowered. Further, as a result of performing a cleaning test with the weak user R and the strong user M, the following results were obtained. User RB / A Strength of force 70g / 7cm = 10 Weak 170g / 8cm = 21 Strong User M 400g / 17cm = 24 Weak 600g / 20cm = 30 Strong Therefore, in the present invention, the power of the cleaning person The range that satisfies even when considering the size (individual difference) is 3 ≦ B
/ A ≦ 55, and it is preferable to configure a cleaning tool in this range.
