Eraser for whiteboard

The present invention relates to an eraser for a whiteboard, and in particular, it is possible to wipe off and erase characters written on a whiteboard etc. without erasing them, and it can be easily magnetically attached to a whiteboard made of a magnetic material. The present invention relates to an eraser for a whiteboard.

Examples of whiteboard erasers that can be magnetically attached to a whiteboard made of a magnetic material include blackboards, whiteboards and other writing board erasers described in Patent Document 1 (hereinafter simply referred to as erasers). This eraser is a general flat horizontal oblong erase structure, and a cloth for ink wiping is adhered to the lower surface of a plastic gripping part that a user grips and erases characters etc. A thin magnet body for adhering the eraser to the white board is bonded to one side of the longitudinal side of the plate.

According to the eraser described in Patent Document 1, there is no need to provide an eraser mounting tray or the like on the lower side of the whiteboard, and there is an advantage that the eraser only needs to be magnetically attached to the whiteboard when not in use. .

However, since the eraser described in Patent Document 1 has the wiping fabric adhered to only one surface of the eraser, once the ink soaks in by erasing characters, the entire eraser including the wiping fabric is replaced. The life of the eraser was short. In addition, since the eraser has a flat rectangular parallelepiped structure, the width of the wiping fabric is wide, and it is possible to erase large characters quickly, but there is a problem that it is difficult to erase small characters.

Furthermore, since the eraser has a flat and horizontally long structure and supports a load of the entire large eraser with a magnet body adhered to the side surface in the longitudinal direction with a relatively small area, it is weak against the pressing force from the vertical direction and easily falls. was there.

In order to solve the above problems, a first object of the present invention is to provide a whiteboard eraser with a long service life that can erase characters on a plurality of surfaces.

The second object of the present invention is to provide an eraser for whiteboard that can be firmly magnetically attached to a whiteboard made of a magnetic material, and can smoothly and quickly erase characters and the like.

The third object of the present invention is to provide a whiteboard eraser that can easily and quickly erase characters written on a large area of a whiteboard and characters written on a small space without erasing them. It is.

In order to achieve the above object, on the surface of the horizontally formed multi-faceted column body, a wiping body capable of erasing characters and the like written on the whiteboard is formed, and on one surface or a plurality of surfaces of the multi-faceted pillar body It is characterized by comprising an eraser body and a gripping member in which a magnetized magnet body is disposed on a white board made of a magnetic material such as steel between the lower surface of the wiping body.

The polyhedral columnar body is a regular rectangular columnar body, and a wiping body made of a sheet such as a nonwoven fabric is fixed to the surface.

The magnet bodies are arranged on opposite surfaces of a regular quadrangular prism body.

The multi-faceted columnar body is an elastic body such as a synthetic resin foam.

The magnet body is embedded in the polyhedral column so that the surface is flush with the surface of the polyhedral column.

Gripping members, characterized in that the case body for detachably accommodating the eraser body

A wiping body capable of erasing characters and the like written on a white board is formed on the surface of the horizontally-oriented polyhedral column body, and one surface or a plurality of surfaces of the polyhedral column body and the wiping body lower surface The whiteboard eraser can be easily magnetically attached to the whiteboard by adopting a structure consisting of an eraser body and a gripping member having a whiteboard magnetic magnet made of a magnetic material such as steel in between. . In particular, if the magnet body is arranged on a plurality of surfaces in the longitudinal direction of the polyhedral column and the wiping body is formed on a plurality of surfaces of the polyhedral column, a plurality of surfaces of the eraser body can be magnetically attached to the whiteboard and a plurality of surfaces It is possible to erase characters written on the whiteboard. In other words, when the ink is soaked into the surface with the wiper due to the erasure of characters, etc., it is possible to erase the characters again by using the other surface that is not soaked with ink. There is no need to replace and discard the entire board eraser each time. Therefore, the service life of the whiteboard eraser is long, which in turn contributes to environmental protection.

The multi-sided columnar body formed in the horizontally long shape is a regular quadrangular columnar body, and a wiping body made of a sheet such as a nonwoven fabric is fixed on the surface, so that any of the four surfaces in the longitudinal direction can be used as a surface for wiping. It can be stored in the case body. That is, if a wiper on one surface is soiled with ink, it can be erased by re-storing it in the case body so that the other surface is the lower surface in contact with the whiteboard. There is no need to replace and discard the entire product each time.

In addition, since the area of the surface to be magnetically attached is the same as the area of the width that protrudes toward the front side of the whiteboard when magnetically attached, the load of the eraser for whiteboard must be supported more firmly than the conventional flat rectangular erasure. Is possible and has the effect of being hard to fall.

Furthermore, if the length in the width direction is made small relative to the longitudinal direction of the whiteboard eraser, a large area can be erased by drawing the whiteboard eraser in a direction perpendicular to the longitudinal direction of the eraser, and in parallel with the longitudinal direction. By dragging, it is possible to erase only the character that is desired to be erased without erasing the adjacent character in a narrow space.

Since the magnet body is arranged on the opposing surfaces of the regular quadrangular prism body, at least two surfaces of the eraser main body can be magnetized, and characters and the like can be easily erased with the wiping body in the magnetized state. .

By making the polyhedral column body an elastic body such as a foam made of synthetic resin, the wiping body closely adheres to the whiteboard due to the elastic force of the polyhedral column body, and the characters etc. written on the whiteboard are not erased. It can be quickly and easily erased. Further, even when the eraser body is housed in the case body, the elastic body is repelled from the case body due to the repulsive force.

The magnet body is embedded in the polyhedral column body so that the surface is flush with the surface of the polyhedral column body, so that characters and the like can be easily erased with a wiping body in a magnetized state. The wiping body closely adheres to the whiteboard, and the characters written on the whiteboard can be erased smoothly and quickly without leaving the characters erased.

The gripping member is a case body that detachably stores the eraser body, so that it is easy for the user to grip, and the surface of the wiping body that has already been infiltrated with ink is stored in the case body to make it dirty. Characters can be erased without touching directly.

The whiteboard eraser 1 shown in FIG. 1 is composed of an eraser body 2 for erasing characters and the like written on the whiteboard, and a case body 6 as a gripping member in which the eraser body 2 is housed and held by a user. Yes.

The eraser body 2 includes a horizontally long polyhedral column 3 as a core material, a wiping body 4 fixed to the surface of the polyhedral column 3, and a magnet disposed between the polyhedral column 3 and the wiping body 4. It consists of bodies 5a and 5b.

As shown in FIG. 2, in this embodiment, the polyhedral column 3 is formed of an elastic body such as a synthetic resin foam that is cut into a regular quadrangular prism shape having substantially the same width L and height H. Has been. In this embodiment, both the width L and the height H are about 3 cm, and the length in the longitudinal direction is about 10 cm. As in the present embodiment, the polyhedral column is preferably a regular quadrangular column, but may be other polyhedral columns such as a triangular column or a flat rectangular parallelepiped.

Further, magnet bodies 5 a and 5 b are arranged between the polyhedral column body 3 and the wiping body 4. In the present embodiment, the surfaces of the two magnet bodies 5a and 5b made of anisotropic permanent magnets are located on the same plane as the surface of the polyhedral column 3 and are embedded so as to be flush with and cover the top. Thus, the wiping body 4 is adhered.

The magnetizing force of the magnet bodies 5a and 5b is such that the load of the whiteboard eraser 1 can be supported by magnetizing through the wiping body 4 and can be easily slid during the erasing operation, as shown in FIG. The whiteboard eraser 1 can be easily magnetically attached to the whiteboard 8 and can be easily slid without dropping, and can be easily slid during the erasing operation. In addition, in this Embodiment, although the magnet body is arrange | positioned on the two surfaces which the polyhedral column 3 opposes, you may arrange | position to all the surfaces and may arrange | position to only one surface.

A case body 6 serving as a gripping member in which the eraser body 2 is housed is a box-shaped case structure that is formed of a synthetic resin such as ABS resin and has a relatively light weight and one opening in the longitudinal direction. The eraser body 2 can be attached and detached. The length of the case body 6 in the longitudinal direction and the width direction is formed to be approximately the same size as the eraser body 2, and the depth of the case body 6 is formed to cover about 2/3 of the eraser body 2. . Therefore, when the eraser body 2 is housed as shown in FIG. 3, about 2/3 of the elastic structure of the eraser body 2 fits inside the case body 6 and the case body 6 holds the upper portion of the eraser body 2 and falls off. Structure to prevent.

Further, the case body 6 has a slope that gently spreads from the bottom to the opening, and a flange 7 is formed on the side of the opening to prevent the eraser body 2 from falling off and to slip when attached / detached. Help Eraser body 2 is easily attached and detached.
