In order to achieve the above object, the eraser for a white board of the present invention is formed on the lower side of the rubber plate to erase the characters written on the handle portion, the rubber plate formed to be fixed to the lower side of the handle portion, and the white board It is formed of a fiber body plate formed shorter than the longitudinal direction of the rubber plate, and the melamine resin foam formed on the lower side of the rubber plate to completely erase the letters of the marker pen remaining on the white board.

The eraser for whiteboard of this invention comprised as mentioned above is demonstrated as follows.

The white board eraser of the present invention is formed with a handle portion 20 that the user can hold by hand.

The lower side of the handle portion 20 is formed to be fitted with a rubber plate 28 having an elastic force, the lower side of the rubber plate 28 is attached to the fiber board 26 to erase the letters of the marker pen written on the whiteboard Is formed.

The rubber plate 28 attached to the fiber board 26 not only has elasticity so that it can be erased while pressing letters written on the white board, and the fiber board 26 is pressed by the rubber plate 28 to be pressed. It prevents lifting from the contact surface of the board.

In addition, the melamine resin foamed body 30 is formed to be connected in succession so as to erase the letters of the marker pen more clearly at the same time with the fiber plate 26.

The melamine resin foam 30 is less friction than other foam resin sponge, high elasticity can be easily removed while pushing the letter ink on the white board.

In addition, the dried granules of the ink erased on the white board by the elastic force and friction of the melamine resin foam 30 is adsorbed to the melamine resin foam 30 to prevent the removed ink is buried again on the white board Do it.

The melamine resin foam 30 is tilted so that the height of the melamine resin foam 30 is not in contact with the white board when the surface of the fiber board 26 is touched to erase the letters written on the white board have.

When the letters written on the white board are erased by using the melamine resin foam 30 formed on the rubber plate 28, the inclination of the wipe surface 31 formed on the melamine resin foam 30 is inclined.

The rubber plate 28 and the melamine resin foamed body 30 may be attached to each other with an adhesive therebetween, and the surface fastener 34 may be formed so as to be replaced by another method.

Therefore, the melamine resin foam 30 of the present invention can be removed by washing off the water when the degree of contamination is severe.

In addition, since the melamine resin foam 30 attached to the rubber plate 28 is not wiped well after the end of its life, the storage part having the lid part 22 on the upper side of the handle part 20 can be replaced. 24 is formed to store a plurality of melamine resin foam 30 in the storage unit.

With reference to the accompanying drawings, the eraser for a white board of the present invention configured as described above will be described in detail as follows.

Figure 3 is a perspective view of the eraser for whiteboard of the present invention, Figure 4 is a cross-sectional view of AA of Figure 3, Figure 5 is a view showing the open state of the lid portion of the eraser for whiteboard of the present invention, Figure 6 is the present invention Fig. 7 is a view showing a modification of the white board eraser, and Fig. 7 is a view showing another modification of the white board eraser of the present invention.

The eraser for a white board of the present invention includes a melanin resin foam body 30 which can remove the coating surface of the white board in detail together with the fiber board 26 which is generally used, and the fiber board 26 as shown in FIG. 3. It is formed on the same surface.

The melamine resin foamed body 30 and the fibrous body plate 26 are formed on the same side and attached to the flat rubber plate 28 to impart an elastic force to one side.

After attaching to the rubber plate 28 as described above, the grip portion 20 of the plastic is fitted to the upper side of the rubber plate 28 so that the user can conveniently hold and use it.

Moreover, it is preferable to make the formation ratio of the fibrous board | substrate 26 and the melamine resin foam body 30 adhering on the rubber board 28 about 3: 1.

First, when erasing a large area of the white board, the fiber board 26 having a large area is used, and the remaining letters, that is, the ink liquid, are shown in the melamine resin foam body 30 as shown in FIG. 3. Rub clean with wipe surface (31).

The melamine resin foamed body 30 is formed to have a slope in the outward direction of the rubber plate 28 longitudinal direction.

Therefore, first, when the letters on the white board are erased by using the fibrous body plate 26 attached to the lower side of the rubber plate 28, they are formed so as to maintain a constant distance from the surface as shown in FIG. .

It is preferable that the angle to which the wiping surface 31 of the said melamine resin foam body 30 was cut | disconnected is made in the range of 4-6 degrees.

That is, if the angle of the wiping surface 31 of the melamine resin foam 30 is formed too low, an abutting portion is generated during the use of the fibrous body plate 26, and easily wiped and contaminated with the fibrous body plate 26, and the wiping surface 31 Too large an angle of the melamine resin foam 30 is a problem that must be used to tilt excessively when clearing the letters on the white board.

Therefore, in the case of erasing letters remaining on the white board, the eraser is inclined to the angular portion formed in the melamine resin foam 30 so that the chamfered wipe surface 31 is brought into contact with and then easily removed.

In addition, the method of adhering the melamine resin foam 30 and the rubber plate 28 to each other is generally irrelevant, but may be adhered using an adhesive, but if the contamination is easy due to the high frequency of use of the melamine resin foam 30, it should be replaced. In order to easily detach and attach the melamine resin foam 30, an adhesive that can be detached and attached between the melamine resin foam 30 and the rubber plate 28, such as a surface fastener 34, is used.

The surface fastener 34 is a melamine resin foam 30 is formed with a movable attachment portion 33, and the other side fixed to the lower side of the rubber plate 28 so that the movable attachment portion 33 is attached and fixed The attachment part 35 is formed.

Therefore, the movable attachment portion 33 formed on the melamine resin foam 30 may be removed from the fixed attachment portion 35 and replaced with another melamine resin foam 30 for another allowance.

Since the melamine resin foam 30 can be easily separated from the rubber plate 28 as described above, when the contamination degree of the melamine resin foam 30 increases after a long time of use, it can be separated, washed in water, reattached, and reused.

When the melamine resin foam 30 can not be washed and reused, the melamine resin foam 30 may be used for a long time, so the amount of wear cannot be increased. At this time, the rubber plate 28 is removed, and then the handle as shown in FIG. The lid portion 22 formed on the upper side of the portion 20 is opened to remove the excess melamine resin foam 30 stored in the inner side of the storage portion 24 and attached to the rubber plate 28 for use. .

The lid part 22 formed on the handle part 20 is closed by closing the plurality of melamine resin foams 30 stored in the storage part 24 as shown in FIG. 3 so as not to be separated.

As described above, the excess amount of the melamine resin foam 30 can be stored in the storage part 24 formed on the upper side of the handle portion 30, so that it does not need to be stored separately, and the melamine resin foam 30 is immediately replaced during use. Can be used.

Further, the bottom surface of the melamine resin foamed body 30, that is, the wiping surface 31 is not formed at an angle, and may be formed to be thinner than the fibrous body plate 26 and attached as shown in FIG.

When the wipe surface 31 of the melamine resin foam 30 is formed in a rectangular shape without maintaining a constant angle as shown in FIG. 6, only the outer part of the melamine resin foam body 30 contacts the white board when the letters on the white board are erased. Only the touching part is contaminated. In this case, remove the melamine resin foam and attach it so that the uncontaminated portion faces outward.

In addition, the melamine resin foamed body 30 can be manufactured by modifying the shape of the rubber plate 28 as shown in FIG.

This forms an angle of the attachment surface of the rubber plate 28 at the time of manufacture, so that the shape of the melamine resin foam 30 can be easily manufactured into a rectangle.

Therefore, according to the present invention as described above it is possible to clean the letters by the surface marker pen on the white board using the melamine resin foam.

In addition, the melamine resin foam having a lower friction than other foam resin sponges can be used continuously without damaging the coating surface of the white board.

In addition, when the surface is contaminated by the number of times of use of the melamine resin foam can not be used to replace the new one can be used for a long time at low cost.
