Description

  The present invention relates to a portable message board in which a white board and a marker are combined.

Conventionally, when inspecting and investigating various buildings such as buildings, bridges, roads, etc., the construction site must be photographed in order to record the current status, damage status, or work status at that time, and use it as material for review and confirmation. Has been done. Specifically, the construction blackboard with the construction name, shooting location, and other special notes is taken together with various buildings. In this case, it consists of a display board having a construction drawing display section for displaying the construction contents and a frame provided with a display board mounting section for arranging the display board on the front. It is known to use a “display tool for construction work” in which leg pieces for standing and supporting a frame body on the ground surface are provided in the frame body (Japanese Patent Laid-Open No. 8-108688 (Patent Document 1 described later). )).

In addition, as a memo writing board that can write and erase memos and events, and can easily attach photos in a fashionable manner, the screen section with photos and drawings, the writing section with blanks, and the back side A board body having an open window part, and a photo storage pocket part for displaying an image from the window part with a photo attached to the back side; and provided for covering at least the front side of the board body for whiteboard There is known a memo writing board with a photograph, which is provided with a transparent case capable of writing and erasing with a marker (Japanese Patent Laid-Open No. 7-228091 (Patent Document 2 described later)).

In addition, it is possible to convey messages and messages with the same writability and erasability as a whiteboard. A re-peelable adhesive layer is provided on the back side of the resin-treated sheet that has the writing and erasing properties of a marker pen. And a releasable pressure-sensitive adhesive layer provided with a release paper on the lower surface thereof, such as a message sheet (Japanese Utility Model No. 3017572) and a whiteboard-like surface that can be used for synthetic resin processing A white note comprising: a plurality of white paper sheets, and a ring-shaped binding tool attached to one end portion of the plurality of white paper sheets or a binding tool for binding one end portion of the plurality of white paper sheets. (Japanese Patent Laid-Open No. 2007-83406) "is known.

However, in order to display the construction site etc. on the display board or message sheet, paste the image print of the construction site where the photograph was taken on the display board or message sheet, write down the required message next to it, Again, there was a need to take a picture with a mobile device such as a digital camera, a mobile phone, or a smartphone, capture the image data, and transmit the content. It took so-called double labor.

On the other hand, the use of magnets for whiteboards has been widely performed. For example, “In an iron plate whiteboard in the shape of a fish, an eraser with a magnet attached to the eye location is adsorbed to the board surface, and a writing implement receiver is provided on the back of the board at the tail wing location, and the writing implement is inserted into the location. There is a white board (Japanese Utility Model Publication No. 51-98637).

In addition, a suction support device in which a magnet is attached to a support device such as a cap shape or a band to support a support object such as a sign pen on a magnetic material such as a whiteboard (Japanese Utility Model Publication No. 54-8069). "A holder formed in a cylindrical shape and capable of holding a writing instrument on its inner peripheral surface, a clip body formed on the outer side of the holder, and attached to the outer side of the holder to a magnetic material A writing instrument accessory characterized by comprising a permanent magnet body that can be magnetically attached (Japanese Utility Model Laid-Open No. 58-86391), “a board body configured to attract a magnet to a surface member, and the board body It has a pen body that can write characters, etc. on the surface member, an eraser that can erase the written characters, etc., and a tray that is molded separately from the board body and has a magnet attached integrally. Known is a white board (Act No. 3078681 (Patent Document 3 to be described later)) characterized in that the tray can be adsorbed to any position of the surface member of the board body and can be removed from the board body. It has been.

In addition, as shown in FIG. 3, a slit is provided in the longitudinal direction of the holder so that the marker is fitted into the holder, “marker adhesion with a magnet fixed to the back surface of the main body on which a clip portion for detachably holding the marker is formed. A tool (Japanese Patent Laid-Open No. 2-160598) is also known. Further, as shown in FIG. 4, the insertion hole at the bottom of the holder is stepped, and “the inside of each writing instrument holder has a stepped taper shape that gradually decreases in diameter from the tip opening toward the base. "A writing instrument stand (Japanese Utility Model Publication No. 59-171982)" is also known.

However, conventional message boards using magnets firmly fix a marker on the whiteboard at an arbitrary position using the magnetic force of a strong magnet on one of the whiteboard and the marker. Therefore, it is not assumed that the marker position is shifted or rotated and fixed at an appropriate position, and such position movement or rotation is difficult. Conversely, if the magnetic force of the magnet is weakened to make it easier to shift or rotate the marker position, the marker has fallen off the whiteboard and the marker cannot be aligned.

For this reason, it has been difficult to select a magnet having an appropriate magnetic force. Also, even if the magnetic marker can be fixed on the whiteboard at any position with the optimum magnetic force, the magnetic force is absorbed by the whiteboard and the magnet deteriorates over time, so it can be used continuously for a long time. I couldn't. That is, as time passes, the magnetic force deteriorates and the marker cannot be moved or rotated well to another predetermined position, and the marker slips off from the whiteboard and cannot be photographed. there were.

JP-A-8-108688 Japanese Patent Laid-Open No. 7-228091 Noto 3078681

The present invention has been made in view of the above problems, and is a portable message that can be fixed at an arbitrary position even when used for a long period of time, and can easily rotate the protrusion of the board body. The purpose is to provide a board.

In order to achieve the above object, the present invention utilizes the property that the horizontal magnetic force of two magnets having a strong magnetic force in the vertical direction is weak. In other words, a board body that sticks even with one end of the pen body while moderately weakening the strong vertical magnetic force between the permanent magnet and the magnet by interposing a non-magnetic non-metallic film between the permanent magnet and the magnet The permanent magnet was made to slide on the plastic film on the magnet by using a weak horizontal magnetic force from the beginning. Furthermore, when two magnets are combined, the property that the magnetic force is not easily lost even if left for a long period of time is utilized.

One of the message boards of the present invention is a message board composed of a board body and a pen body. The board body is a disk body having a protrusion on the outer periphery, and a magnet is embedded in the center of the disk body. On the other hand, the pen body is composed of a marker and a holder, and the holder has a permanent magnet on its side wall, an insertion hole on its lower part or another side wall, and the magnet and the permanent magnet. A nonmagnetic nonmetallic film is provided between them.

Another of the message boards of the present invention is a message board comprising a board body and a pen body. The board body is a disk body having a protrusion on its outer periphery, and a magnet is provided at the center of the disk body. The surface of the magnet is buried and covered with a plastic film. On the other hand, the pen body is composed of a marker and a holder, and the holder has an insertion hole in the lower part or another side wall, and the permanent magnet is provided on the side wall. And the radius of the disc body is shorter than the total length of the pen body.

The preferred embodiments of the present invention are as follows.
The magnet is preferably a solid cylinder rather than a hollow cylinder. The surface of the permanent magnet is preferably covered with a resin film. Moreover, it is preferable that the area of the permanent magnet has a facing surface that is the same as the area of the magnet. Moreover, it is preferable that the said permanent magnet forms the convex part of the said pen body. Moreover, it is preferable that the radius of the said disc body is shorter than the full length of the said pen body. The insertion hole preferably has a cap shape of the marker. The message board is preferably for taking a picture.

In the present invention, the non-magnetic non-metal film refers to a thin sheet of plastic or paper having good slipperiness with respect to the metal surfaces of the magnet and permanent magnet. If non-magnetic plastic or paper is used, the magnetic force is not blocked. Therefore, the types and sizes of magnets and permanent magnets are determined according to the weight of the board body and pen body, the thickness of the thin sheet is adjusted appropriately according to the strength of the magnetic force, and the vertical attractive force and horizontal The rotational force in the direction was determined.

In the present invention, the magnet and the permanent magnet are used for the board body and the pen body, using the property that the two adsorbed magnets are easily rotated, the board body and the pen body are bonded, and one end of the pen body is held. This is because the board body can be held.

Examples of magnets include ferrite magnets, rare earth magnets, alnico magnets, platinum cobalt magnets, and the like, and rubber magnets and plastic magnets obtained by kneading these magnet powders with rubber or plastic. Preferably, a samarium cobalt magnet or neodymium magnet having a strong holding force is preferable. If a neodymium magnet or the like having a strong holding force is used for the magnet and the permanent magnet, the surface of the magnet can be covered with various plastic films.

If the magnet is of a solid cylindrical body, so-called disk shape, the center axis alignment of the board body and the pen body is simplified. In this case, the permanent magnet can be a hollow or solid cylinder. If the area of the permanent magnet has a facing surface with the same area as the magnet, the center of rotation of the board body will not shift. Further, when the board body is large, a hollow magnet or a plurality of magnets can be used. A hemispherical permanent magnet can also be used for the pen body.

Further, when the surface of the magnet is covered with a plastic film in particular, sliding between the magnet and the permanent magnet is easier than the thin film of paper, and it is easier to rotate. That is, when rotating the board body, a weak magnetic force works, so less finger force is required, and when the board body moves away from the pen body, a strong magnetic force works even if it is through a plastic film. The adsorption state can be maintained.

Even if the magnet and the permanent magnet are in direct contact with each other, the sliding frictional resistance between metals is large and the attractive force is strong, so that the magnet cannot be rotated well. Further, if the magnet and the permanent magnet are in direct contact with each other, dust such as magnetic powder accumulates on the contact surfaces of the magnet and the permanent magnet, making it difficult to rotate.

When a magnet having a strong magnetic force is covered with a plastic film or the like, the plastic film and the resin film or the thin film of paper and the permanent magnet are in direct contact with each other, so that sliding between the board body and the pen body is improved. As a result, the board body can be easily rotated on the pen holder. In order to make it more slippery, the surface of the permanent magnet is also preferably covered with a thin film such as a resin. Since the distance between the magnet and the permanent magnet increases depending on the thickness of the plastic film or resin film, the strength of the magnetic force can be adjusted. If the surface of the magnet or permanent magnet is covered with a resin film, even if dust such as magnetic powder adheres, it can be easily wiped away.

Further, in the present invention, when the total length of the pen body is longer than the radius of the disk body of the board body, the pen body is held with one hand, the object is pointed at the protrusion of the board body, and the photograph can be taken with the opposite hand. it can. The protrusions provided on the outer periphery of the disc body in the board main body preferably have an isosceles triangle shape or an arrow shape for easy understanding of the index.

In the present invention, the holder is for holding an existing marker. When the marker does not have a cap, the marker can be held and ink can be prevented from evaporating by having an insertion hole in the lower part of the holder. When the insertion hole of the holder is made into the cap shape of the marker, it is not necessary to produce an independent cap body, and the cap is not lost. Further, when the marker is consumed, only the marker can be replaced and used.

A plurality of insertion holes at the bottom of the holder can be used in a plurality so as to correspond to a plurality of markers. Alternatively, the insertion hole at the bottom of the holder may be stepped so that a marker having a plurality of diameters and core lengths can be inserted with a single holder. Although the tip of the insertion hole is closed, a slit groove may be provided in the side body portion of the insertion hole so that markers having different diameters can be inserted. An eraser can also be provided on the top of the holder.

Also, in the present invention, the message board is preferably used for taking a picture, because the pen body can be held with one hand and the subject can be easily pointed with the triangular protrusion, so that a short message is displayed on the board body. This is because it is possible to change a plurality of subjects one after another while writing many times. Content such as captured images and videos can be uploaded and transferred immediately via the Internet. The color of the board body is generally white, but light red, blue, yellow may be used, or black may be used.

According to the message board of the present invention, since the magnetic force is strong, the board body does not rotate or slide down from the pen body, and the subject can be pointed at the correct position at any angle. Therefore, it can be used for not only emergency contact but also easy mobile mail transmission such as food introduction. In addition, according to the message board of the present invention, a simple message can be written on the board, so that there is a double troublesome time to photograph a subject and paste it on a whiteboard as before and write a message. It becomes unnecessary.

Furthermore, according to the message board of the present invention, it is possible to take a picture with the opposite hand while holding the pen with one hand and pointing the subject with the triangular protrusion. Further, according to the message board of the present invention, the powder and pieces of the magnetic material stuck on the magnet can be easily wiped, so that the message board of the present invention can be used with a constant magnetic force. Further, if the insertion hole is matched to the diameter of a commercially available marker, even if the marker is consumed and cannot be written, the marker can be easily replaced and the message board of the present invention can be used repeatedly.

Embodiments of the invention will be described in detail with reference to the drawings as appropriate.
FIG. 1 is a board body of a message board according to an embodiment of the present invention, in which (a) is a front view thereof and (b) is a cross-sectional view taken along line AA. As shown in FIG. 1, the board body 1 of the message board is based on a disc body having a thickness of 3 mm and a diameter of 80 mm, and has a triangular protrusion 2 having a width of 8 mm and a length of 15 mm on the outer periphery thereof. A solid cylindrical magnet 3 (outer diameter 8 mm × height 2 mm) is embedded in the center, and a plastic film 4 having a thickness of 0.3 mm is laminated on the entire back surface. Moreover, although the surface of the board main body 1 is not shown in figure, the transparent film (thickness 0.4mm) of a polyvinyl chloride is laminated | stacked on the white paper stand, and comprises the white board.

On the other hand, as shown in FIG. 2, the pen body 5 has an eraser 8 (width 10 mm × length 10 mm × length) in a holder 7 (total length 120 mm including the markers 6) into which a marker 6 (outer diameter 9 mm × total length 100 mm) is inserted. A height of 5 mm) is attached. The holder 7 has an insertion hole 10 (inner diameter 8 mm × depth 27 mm) for aligning the marker 6 therein, and a solid cylindrical permanent magnet 12 (outer diameter 8 mm × height 2 mm) embedded in the side wall thereof. It is. The permanent magnet 12 of the pen body 5 is fixed with a heat-shrinkable resin film 14 (thickness 0.3 mm).

Next, in order to measure the magnetic force of the neodymium magnet of the magnet 3 and the permanent magnet 12, the magnet 3 and the permanent magnet 12 were directly attached, and the force at the time of peeling was measured. One end of a rubber band (inner diameter 30 mm × width 3 mm × thickness 0.7 mm) was bonded to the magnet 3, and the magnet 3 was directly attracted to the permanent magnet 12, and then the magnet 3 was peeled off. At this time, the rubber band adhesive was peeled off from the magnet 3 when the elastic band extended 140 mm or more from the natural length. Further, the board main body 1 was attached to the magnet 3, the permanent magnet 12 was held with radio pliers, and the protrusion 2 of the board main body 1 was rotated with a finger, but it did not rotate.

Next, when the plastic film 4 was interposed between the magnet 3 and the permanent magnet 12 and they were attached to each other, and the force for peeling was measured, the stretch of the rubber band was increased by 110 mm from the natural length. At this time, when the protrusion 2 was turned with a finger, it turned easily. Furthermore, when the plastic film 4 and the resin film 14 were interposed between the magnet 3 and the permanent magnet 12 and the two were attached to each other, and the force at the time of peeling was measured, the elongation of the rubber band was increased by 90 mm from the natural length.

  As is clear from the above results, it can be seen that the strong magnetic force in the vertical direction between the magnet 3 and the permanent magnet 12 can be adjusted by interposing the plastic film 4 and the resin film 14. Therefore, if the protrusion 2 of the message board is aligned with the subject and the pen body 5 is held, the board body 1 can be firmly held at the position of the subject. Further, when the plastic film 4 is interposed or when the plastic film 4 and the resin film 14 are interposed, the force for turning the protrusion 2 of the board body 1 is weak in any case and can be easily rotated. I understand.
