Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning sponge used for cleaning floors, tiles, window glass, car bodies, and the like.

[0002]

[Problems to be solved by conventional techniques and devices]

 When a soft sponge material such as a cellulose sponge is moistened with water to wipe a surface to be cleaned such as a floor surface, the sponge material absorbs dirt and dust, thereby cleaning the surface to be cleaned. However, dirt that has clinged to the surface to be cleaned to some extent cannot be separated from the surface to be cleaned simply by wiping it with a soft sponge material, and it is necessary to remove such dirt using another cleaning tool. As a result, it was one of the factors that reduced the efficiency of cleaning work.

The present invention has been made in view of the above problems existing in the prior art, and an object of the present invention is to scratch dirt on a surface to be cleaned with dirt sticking to the surface to be cleaned. It is an object of the present invention to provide a cleaning sponge body that can be effectively and effectively separated from the surface to be cleaned without any need.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the cleaning sponge body of the present invention comprises a sponge body having relatively high water absorbency and flexibility and a rubber plate body having relatively low flexibility. With the end edge of the rubber-like plate located on the surface of the rubber plate, both sides of the rubber-like plate are sandwiched between the slit-like parts provided in the sponge body. Both side surfaces of the edge portion are not fixed to the slit-shaped portion.

[0005]

[Operation] When the sponge body is wetted and the surface to be cleaned is wiped with the surface where the edge of the rubber plate body is located on the surface using the sponge body, the surface portion of the sponge body and the rubber plate The edge of the body moves while contacting the surface to be cleaned.

At least the edge portion of the rubber-like plate body is not fixed to the slit-like portions on both side surfaces thereof, and has a high degree of freedom with respect to the sponge body. Therefore, when the sponge body receives a compressive force between the surface to be cleaned and a shearing force from the surface to be cleaned, the edge of the rubber-like plate may protrude from the surface of the sponge body. , Deforms with sponge body or independently of sponge body.

[0007] The sponge body absorbs dirt and dust on the surface to be cleaned, and when the dirt adheres to the surface to be cleaned, the edge of the rubber-like plate body having relatively low flexibility damages the surface to be cleaned. It effectively separates the surface to be cleaned, and the sponge absorbs the separated dirt.

Since both sides of the rubber-like plate are sandwiched between the slit-shaped portions provided in the sponge body, even if the surface to be cleaned is wiped while moving the sponge body in any direction, at least The side surface of the base of the rubber-like plate is supported by the sponge bodies on both sides of the slit-shaped portion. Therefore, the durability of the rubber-like plate body held by the sponge body is good.

【Example】

 Embodiments of the present invention will be described with reference to the drawings. 1 to 4 relate to a cleaning tool as one embodiment of the present invention, in which FIG. 1 is a front view of a main part, FIG. 2 is a bottom view, and FIG. 3 is a side view of a main part of a rubber plate. 4 and 5 are front views of the main part.

The cleaning sponge body 10 is made of cellulose with fine mesh and has relatively high water absorbency and flexibility. The sponge body 10 has a rectangular parallelepiped shape, and has two parallel slit-shaped portions 12 opening to the bottom surface 10a between both ends in the longitudinal direction. In this embodiment, the depth of the slit-shaped portions 12 is about one half of the thickness of the sponge body 10.

A rubber plate 14 having a substantially rectangular shape, which is relatively less flexible than the sponge body 10, is fitted into each slit 12. The upper end portion 14a of the rubber-like plate member 14 slightly expands to both sides and bites into both side walls of the upper end portion of the slit-like member 12 of the sponge member 10, and the upper portion of the rubber-like plate member 14 and the slit-like member 12 are separated from each other. Both side surfaces are bonded with an adhesive 16. This prevents the rubber-like plate body 14 from falling off the slit-like portion 12.

As shown in FIGS. 3 and 4, a large number of small protrusions 18 are evenly provided on both sides of the lower portion 14 b of the rubber-like plate body 14, and the lower portion 14 b of the rubber-like plate body 14 and the slit are provided. It is not adhered to the shape portion 12. Both sides of the lower portion 14b of the rubber-like plate member 14 are not fixed to the slit-shaped portion 12 and have a high degree of freedom with respect to the sponge member 10.

A pipe 20 is embedded in the sponge body 10 at an intermediate position in the longitudinal direction of the left and right center portions in FIGS. 1 and 2, and cuts (not shown) provided at both ends of the pipe 20 on the upper side of the sponge body 10. ), The ends of the fittings 22 connected to the handle (not shown) of the cleaning tool are fitted into both ends of the pipe 20.

When the surface to be cleaned is wiped at the bottom surface 10a while the sponge body 10 is soaked in water and moved in the lateral direction, the bottom surface 10a of the sponge body 10 and the lower end portion of the rubber-like plate body 14 are cleaned. The rubber-like plate 14 moves in a direction orthogonal to the side surface while contacting the surface.

Since the lower portion 14b of the rubber-like plate 14 has a large degree of freedom with respect to the sponge body 10, the sponge body 10 receives a compressive force between the handle and the surface to be cleaned, or a shear force from the surface to be cleaned due to friction. Upon receiving, the lower end of the rubber plate 14 projects from the bottom surface 10a of the sponge body 10 or is deformed together with the sponge body 10 or independently of the sponge body 10.

As a result, the sponge body 10 absorbs dirt and dust on the surface to be cleaned, and as for the dirt stuck to the surface to be cleaned, the lower end portion of the rubber plate 14 having a relatively low flexibility is the surface to be cleaned. Is effectively separated from the surface to be cleaned without damaging it, and the separated dirt is absorbed by the sponge body 10. Since many small protrusions 18 are evenly provided on both sides of the lower portion 14b of the rubber-like plate body 14, the lower end portion of the rubber-like plate body 14 projects from the bottom surface 10a of the sponge body 10 or together with the sponge body 10. Alternatively, by deforming independently of the sponge body 10, the group of small protrusions 18 moves while being in contact with the surface to be cleaned to enhance the effect of separating dirt from the surface to be cleaned.

The rubber-like plate body 14 is substantially impermeable to water. Therefore, the water absorbed by the sponge body 10 is prevented from leaking through the rubber-like plate body 14.

Since both sides of the rubber plate 14 are sandwiched between the slit-like portions 12 provided in the sponge body 10, the sponge body 10 can be moved in any direction while the surface to be cleaned is moved. Even if it is wiped, at least the upper side surface of the rubber-like plate member 14 is supported by the sponge members 10 on both sides of the slit-shaped portion 12. Therefore, the durability of holding the rubber plate 14 by the sponge body 10 is good.

The bottom shapes of the slit-shaped portion 12 and the rubber-like plate body 14 are not limited to the linear shape of this embodiment, and may be, for example, a bent shape, a zigzag shape, an arc shape, or various closed curve shapes. .

The dimensions, the number, the material, the shape, the relative arrangement, etc. of the constituent parts in the description of the above embodiments are limited only to those unless otherwise stated. It is not intended to be limited to the above and is merely an example of description.

[0021]

[Effect of device]

 In the cleaning sponge body of the present invention, the sponge body is moistened with water, and the sponge body is used to wipe the surface to be cleaned at the surface where the edge of the rubber plate is located on the surface. The rubber plate effectively separates the dirt clinging to the surface to be cleaned, while the sponge body absorbs dirt and dust on the surface to be cleaned so that the surface to be cleaned can be efficiently cleaned. Will not hurt. Further, such an effect is maintained for a long period of time because the durability of the rubber-like plate body held by the sponge body is good.
