Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a whiteboard eraser for erasing characters, figures, symbols, etc. drawn on a whiteboard with a whiteboard marker.

[Conventional technology]

Conventional whiteboard erasers have a structure in which an elastic core material such as a sponge is covered with a cloth material such as vettin or mohair with a handle attached to the wiping part, or a cloth material is stretched around the entire circumference of the elastic core material. There is a structure in which the wiping part is removably fitted into a box-shaped case with one side open, and the wiping surfaces of the wiping part can be changed to two or four sides.

[Problem that the invention attempts to solve]

However, when wiping off certain kinds of dirt such as pigments and resin components in the conventional laser and markers mentioned above, the wiping surface of the dirty wiping part is always exposed to the outside. It may stain things. Furthermore, with the latter eraser, it is necessary to manually remove the wiping portion contaminated with the marker from the case, which may stain your hands.

An object of the present invention is to provide a whiteboard eraser that is easy to handle and does not cause the risk of staining hands or objects around the whiteboard.

[Means for solving problems]

In this invention, an elastic material is wrapped around the bottom plate of a pedestal with both ends of a flat plate raised up, and two winding shafts each having a stepped portion at both ends can be attached/detached and rotated to the upright plate part of the pedestal. Wrap a wiping material whose width is larger than the width of the elastic material around the two winding shafts, and stretch the wiping material around the elastic material so that the inner winding surface of the wiping material becomes the wiping surface. Then, a box-shaped case with one side open is removably fitted onto the upright plate part of the pedestal, and the width of the side wall corresponding to the upright plate part of the pedestal is the width between the upright plate parts of the pedestal. It is characterized in that it is made smaller and at least one of the two winding shafts protrudes from the case.

[Effect]

In the present invention, by winding up the wiping material with the wiping surface inward using the winding shaft, a new wiping surface is always exposed to the outside. In addition, a large frictional force acts between the elastic material and the wiping material, and the rising plate of the pedestal presses the stepped part of the winding shaft inside through the case, causing a brake to act on the winding shaft. , there is no displacement of the wiping material.

〔Example〕

Hereinafter, an embodiment of the whiteboard eraser according to the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a pedestal, and this pedestal 1 is made by raising both ends of a plate material, and consists of a bottom plate part 10 and a rising plate part 11, and step parts 12 are provided at both ends of the bottom plate part 10, Two notches 13 are provided in one rising plate part 11 from the upper edge of the rising plate part 11 to approximately the middle part, and two through holes 14 are provided in the other rising plate part 11 corresponding to the notches 13. Let's set it up. Reference numeral 2 denotes an elastic material made of felt, sponge, etc., and this elastic material 2 is wound between the stepped portions 12 of the bottom plate portion 10 of the base 1. 3 is a winding shaft having stepped portions 3 formed at both ends,
Insert one end of the winding shaft 3 into the through hole 14 of the pedestal 1, drop the other end of the winding shaft 3 into the notch 13 of the pedestal 1, and insert the two winding shafts 3 into the upright plate of the pedestal 1. It is rotatably and detachably attached to the section 11. The two winding shafts 3
A take-up 30 is provided on one of the winding shafts 3. Reference numeral 4 is a wiping material made of paper or the like, and the width of this wiping material 4 is slightly larger than the width of the elastic material 2 (6 to 10 mm).
mm) is large and is wound around two winding shafts 3. For example, as shown in FIG. 3, one side edge of the wiping material 4 is wound counterclockwise around the winding shaft 3 (on the right) without the winding 30, and the winding shaft (on the left) with the winding 30 is wound counterclockwise. The other side edge of the wiping material 4 is fixed to 3. The two winding shafts 3 are placed on the pedestal 1.
When attaching the wiping material 4 to the elastic material 2, the wiping material 4 is stretched from the top surface to the bottom surface of both ends of the elastic material 2 so that the inner winding surface of the wiping material 4 becomes the wiping surface. Reference numeral 5 denotes a case that also serves as a handle, and this case has a hollow box shape with one side (bottom) open, and when it is fitted onto the upright plate part 11 of the pedestal 1 mentioned above, it will fit into the upright plate part 11. The width of the adjacent side walls 50 is made slightly smaller than the width between the upright plate parts 11 of the pedestal 1, and a notch 51 is provided in one of the side walls 50 from the lower edge of the case 5 to approximately the middle part, Further, an engaging claw 52 is provided to protrude downward from the center of the lower edge of the side wall 50. A groove 53 is provided at the base of the engaging claw 52 with the side wall 50, and the engaging claw 5
Give elasticity to 2. This case 5 is removably fitted onto the upright plate portion 11 of the pedestal 1, the notch 51 of the case 5 is taken, and the case 5 is inserted into the winding shaft 3 having the 30. Standing plate part 11 of
removably engages the lower edge of the.

The whiteboard eraser of the present invention in this embodiment has the above configuration, and its operation will be described below.

Once the characters, figures, symbols, etc. drawn on the marker on the whiteboard have been wiped off with the wiping surface of the wiping material 4, turn the camera 30 in the direction of the arrow and remove the wiping material 4 stained with the marker from the wiping surface. Turn it inside and wind it up on the winding shaft 3. At this time, the wiping material 4 wound around the other winding shaft 3 is rewound to expose a new wiping surface. Therefore, there is no risk that the marker's stains will stain the operator's hands or objects around the whiteboard. Further, since the wiping material 4 is wound around the winding shaft 3 so that the dirty wiping surface is on the inside, the user does not get his hands dirty when replacing the wiping material 4. Further, since the width of the wiping material 4 is larger than the width of the elastic material 2, there is no risk of staining the elastic material 2 with the marker. Furthermore, since the wiping material 4 was stretched from the upper surface to the lower surface of both ends of the elastic material 2 so that the inner winding surface of the wiping material 4 became the wiping surface, there was a gap between the wiping material 4 and the elastic material 2. Since a large frictional force acts and the width of the side wall 50 of the case 5 is smaller than the width between the upright plate portions 11 of the pedestal 1, when the case 5 is fitted onto the upright plate portions 11 of the pedestal 1, as shown in FIG. As shown in FIG.
is pressed, and a brake is applied to the winding shaft 3.
As a result, even if the marker on the whiteboard is wiped off with the wiping surface of the wiping material 4, the wiping material 4 will not shift. Further, by simply operating the camera 30, the dirty wiping material 4 can be wound up and a new wiping material 4 can be fed out. Furthermore, since the case 5 is removably attached to the pedestal 1, and the two winding shafts 3 are detachably attached to the pedestal 1,
The wiping material 4 can be easily replaced.

In this embodiment, two winding shafts 3 are used.
One of the winding shafts 3 is made to protrude from the case 5 to provide the camera 30, but two winding shafts 3
may be made to protrude from the case 5, and the two winding shafts 3 may be provided with picks 30. In this way, the winding shaft 3 on which the new wiping material 4 is wound is operated to feed out the new wiping material 4, and the other winding shaft 3 is operated to unwind the dirty wiping material 4 onto the winding shaft. By winding up the wiping material 4, it is possible to easily wind up the wiping material 4 with a small force.

Furthermore, since the case 5 is provided with the engagement claw 52, the case 5 will not come off from the base 1 by engaging the engagement claw 52 with the lower edge of the upright plate portion 11 of the pedestal 1. .

[Effect of idea]

As is clear from the above, in the whiteboard eraser of the present invention, the wiping material is wrapped around two winding shafts, so by operating the winding shafts, the wiping material stained with markers can be wound up. A new wiping material can be fed out and the wiping surface of the new wiping material can always be exposed to the outside. Furthermore, since the wiping material is wound around the winding shaft so that the dirty wiping surface is on the inside, there is no risk of staining hands with markers when replacing the wiping material. Furthermore, since the width of the wiping material is larger than the width of the elastic material, there is no risk of staining the elastic material with the marker. Therefore, the marker does not stain the operator's hands or objects around the whiteboard.

Moreover, since the wiping material is made of an elastic material and is stretched so that the inner winding surface of the wiping material becomes the wiping surface, a large frictional force acts between the wiping material and the elastic material, and the side wall of the case is Since the width is smaller than the width between the rising plates of the pedestal, by fitting the case onto the rising plate of the pedestal, the rising plate presses the stepped part of the inner winding shaft and the winding shaft The brake is applied. As a result, it is possible to prevent the wiping material from shifting. Also,
The wiping material can be wound up or fed out simply by operating the winding shaft. Furthermore, since the case and the two winding shafts are removably attached to the base, the wiping material can be easily replaced. Therefore,
An easy-to-handle eraser can be provided.
