Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a wipe for a whiteboard. More specifically, it relates to a wipe for a whiteboard that is widely used in place of a conventional blackboard in schools, offices, homes and the like.

[Prior Art] As a conventional wiping tool for whiteboards, the actual exploitation 57-24
There are those described in JP-A-099 (conventional example I) and JP-A-60-8099 (conventional example II).

In the conventional example I, a rectangular closed-cell plastic body is electro-implanted with fibers on at least the upper surface or the side surface and the back surface.

In the conventional example II, a single yarn having 20 to 80 filaments is
It is made of pile fabric woven at a density of 1,000 threads / square inch, and the height of the single yarn from the base fabric surface is 2 to 10 mm.

[Problems to be Solved by the Invention] However, the conventional example I has a problem that when the surface of the whiteboard is wiped off, the powder of ink is wiped off to contaminate the surrounding air and cause unwiping.

In addition, the conventional example II is complicated to manufacture and costly, and has not solved the same problem as the conventional example I.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wiping tool for a whiteboard that does not scatter ink powder and can be wiped off without leaving an unwiped portion.

Another object of the present invention is to provide a wiping tool that can be manufactured and used at low cost.

[Means for Solving the Problem] The white hood wiping device of the present invention is a white board wiping device in which a wiping cloth made of non-woven tuxpan is removably attached to the outer surface of the pad. A state in which both ends of a wiping cloth are sandwiched between a fixing plate fixed to the upper surface of the pad and having both side edges raised, a holding plate that fits between both side edges of the fixing plate, and the holding plate and the fixing plate. It is characterized in that it is provided with a pressing plate fixing tool which is pressed against the fixing plate.

In the present specification, the tax-pan non-woven fabric refers to a non-woven fabric in which a thermoplastic resin is melted and a pile-like fluff is formed on the surface of the base fabric by utilizing the thread-pulling phenomenon. It has a length of about 40 mm.

[Operation] The tax-pan nonwoven fabric, which is the wiping cloth of the present invention,
When the surface of the whiteboard is wiped off, the hairs are long, and the hairs rub against each other and the hairs and the whiteboard rub against each other to generate static electricity, and the ink powder is adsorbed so that it does not scatter around. Therefore, the surrounding air is not polluted and the whiteboard surface can be wiped well.

The tax pan non-woven fabric used in the present invention can be mass-produced and manufactured at low cost. Moreover, in the present invention, if the wipe cloth is cut into an appropriate size and replaced with a new one every time it becomes dirty. Since it is good, it can be used at low cost.

[Example]   Next, an embodiment of the present invention will be described.

FIG. 1 is a perspective view of a whiteboard wiper according to an embodiment of the present invention, FIG. 2 is an exploded perspective view of the wiper shown in FIG. 1, and FIGS. 5 is a cross-sectional view showing the action of the above, FIG. 5 is a structural explanatory view of the tax pan nonwoven fabric, and FIGS. 6 to 7 are explanatory views showing a method for producing the tax pan nonwoven fabric.

1 and 2, (1) is the whiteboard wiper of the present embodiment, (2) is a pad, (3) is a fixing plate fixed to the upper surface of the pad (2), and (4) is a presser foot. Board,
(5) is a holding plate fixing tool, and (6) is a wiping cloth.

Pad (2) is made of styrene foam or urethane foam,
It is made of a cushioning material such as felt. The illustrated pad (2) is a rectangular parallelepiped, but may have any shape such as a semi-cylindrical shape. The fixing plate (3) is a molding plate made of a synthetic resin such as acrylic resin or vinyl chloride resin, with both side edges (7) rising, and is fixed to the upper surface of the pad (2) with an adhesive or the like. A hole (8) is formed in the center of the fixing plate (3). The holding plate (4) is a synthetic resin molded plate similar to the fixed plate (3) and has a width that fits between the both side edges (7) of the fixed plate (3). A hole (9) is formed in the center of the holding plate (4) (see FIG. 3).

The fixture (5) comprises a main body (11) and a locking portion (15) as shown in FIGS. The body (11) has a shaft (12),
It consists of a knob (13) formed at one end and a head (14) formed at the other end. The head (14) has a larger diameter than the shaft (12). The locking part (15) is the boss (16)
And an elastic claw (17) extending from the boss (16).
A flange portion (18) is formed on the upper end of the boss (16).

As shown in FIG. 3, the head (1
When 4) is inside the cavity of the elastic claw (17), the outer diameter of the elastic claw (17) is small and the hole (8) of the fixing plate (3) can be freely inserted and removed. it can. As shown in FIG. 4, when the head portion (14) is in contact with the inner circumference of the tip end portion of the elastic claw (17), the outer diameter of the elastic claw (17) is widened and the fixing plate (3) It does not come out of the hole (8).
Then, in this state, a space (d) necessary for holding the wiping cloth (6) is created.

Then, as shown in FIG. 2, the wiping cloth (6) is wound around the pad (2), and both end edges thereof are folded on both side edges (7) of the fixing plate (3). The wiping cloth (6) can be easily attached by holding the holding plate (4). Further, since the fixing tool (5) is easily attached and detached, the wiping cloth (6) can be easily replaced.

The wiping cloth (6) is obtained by cutting a tax pan non-woven fabric into a size necessary for winding the pad (2).

Next, the tax pan nonwoven fabric used in the present invention will be described.

As shown in FIG. 5, Tuckspun nonwoven fabric (20)
Consists of a base cloth (21) and a pile-like fluff (22). As the base fabric (21), non-woven fabric, woven fabric or the like is used.
As the material of the fluff (22), a thermoplastic resin such as polyethylene or polypropylene is used.

The production method of this tax bread nonwoven fabric (20) is as follows:
The method as shown in the figure is taken. Here, the base cloth (21) and the thermoplastic resin (22a) are passed through a heating roll (23) to melt the thermoplastic resin (22a), and the stringing phenomenon is caused between the base cloth (21) and the roll (23). Then, the base cloth (2
When the nozzle (24) blows an air stream from the back surface of 1) to cool the yarn and cut the yarn, pile-like fluff is formed. In this case, a long pile of about 5 to 40 mm is formed. In addition, as shown in FIG. 7, when an air flow is blown from the surface side of the base fabric (21) by the nozzle (24), about 2 to 2
A short pile of 10 mm is formed.

The tuxpan non-woven fabric used in the present invention needs to generate static electricity due to friction between the fluff and between the fluff and the whiteboard.
mm is preferably used.

[Advantages of the Invention] According to the present invention, the ink powder on the whiteboard is not scattered, and there is no unerased residue, so that the whiteboard can be wiped off well.
