Description

  The present invention relates to a relatively small magnetic attraction type board that can be used even in ordinary homes among boards used as a written display or a bulletin board for display objects, such as a blackboard or a white board.

  Conventionally, in the display of written indications and display objects, as represented by the blackboard used in school education, etc., a large receiving member that also serves as a powder receiver that can be used for white ink and blackboard wiping has been installed below it Configurations are known.

On the other hand, in recent years, small white boards and small bulletin boards that can be written and erased using felt pens that use water-based or alcohol-based inks that can be used at home have become widespread. Yes.
These small boards may be of a type having no receiving member, but those having a receiving member are also known.

  That is, Patent Document 1 discloses a rubber magnet whiteboard in which a thin plate-like synthetic resin is applied to the surface of a rubber magnet, a hanging metal fitting is provided on the upper part, and a pen tray is provided on the lower part.

  Patent Document 2 uses a writing body in which a synthetic resin film is bonded to a core material of cardboard or a synthetic resin foam, and two or more holes are provided in the vicinity of the central lower end thereof. The structure which inserts and attaches the both ends of the support piece for pen placement which consists of flat form is disclosed.

Japanese Utility Model Publication No. 62-107995 Japanese Utility Model Publication No. 63-33992

However, in the technique of Patent Document 1, a specific method for attaching the pen tray to the rubber magnet is not disclosed, and it is usually interpreted that the pen tray is attached by adhesion or the like. Since care must be taken to prevent the agent from sticking out, soiling, and the position of the pen tray being displaced, inconveniences in productivity are likely to occur.
In addition, it is possible to imagine a configuration in which the pen tray is attached to the rubber magnet by magnetic attraction, but in this case, the pen tray must be made of a ferromagnetic material such as a steel plate, In addition, there is a need for a process that does not cause sharp burrs and the like, and there is a technical problem that a sufficient magnetic attraction force must be ensured so that it does not move easily when it comes into contact with the pen tray.

  Moreover, in the technique of patent document 2, in order to insert the support piece for flat-plate-shaped pen holders in the form provided in the cursive body so that the flat plate surface may become vertical, it matches the upper end surface. If it is not a pen of the form to be placed, there is a disadvantage that it is difficult to place and easy to fall, and because the end surface of the support piece for pen placement is inserted against the writing body, if a load is applied to the support piece for pen placement The inconvenience in strength that the end face bites into and is easily damaged is expected.

  Accordingly, the present invention provides a magnetic member with a receiving member that is easy to mount the receiving member and can secure a stable mounting strength, and is excellent in productivity and performance, in order to eliminate these disadvantages in the prior art. It is an object to provide an adsorption board.

  In order to solve the above-mentioned problems, the present invention is a result of earnest examination of utilizing the action of magnetic attraction force that attaches the board to the ferromagnetic article without using the structure of the board in which the receiving member is attached from the beginning. Specifically, it consists of a magnetic adsorption type board and a receiving member that can magnetically attract the back of a ferromagnetic article, and the magnetic adsorption type board is punched through the back from the surface. The receiving member is formed with an accessory receiving portion having a horizontal or upward inclined surface or a substantially L-shaped cross section, and a vertical retaining portion provided at the rear portion thereof. Can be inserted and locked to the punched part of the magnetic adsorption type board so that the accessory receiving part does not come out, and from the locked state, the back side of the magnetic adsorption type board is magnetically adsorbed to the ferromagnetic article The And when, retaining portion has been indirectly attached is configured by being held between the ferromagnetic material article and the magnetic entrapment board.

By adopting such a configuration, the receiving member is not attached to the magnetic adsorption type board from the beginning, so the product is simply packaged as a disassembled member. Since it is only necessary to insert directly from the back side of the magnetic adsorption type board, it can be easily performed.
Note that when the magnetic adsorption type board is magnetically adsorbed to the ferromagnetic article, the retaining member enters between them, and from this state, it does not come out of the punched part formed on the magnetic adsorption type board. Because it is not, it is indirect, but it will be securely attached.

Further, the magnetic adsorption type board is formed of a flexible magnet sheet, and when it is magnetically attracted to the ferromagnetic article with the receiving member inserted, the retaining portion formed on the receiving member is magnetic. It can be set as the structure by which an adsorption | suction board | substrate is hold | maintained between ferromagnetic materials by deform | transforming flexibly.
According to this configuration, since the retaining portion formed on the receiving member is held without a gap, there is an advantage that the mounting state of the receiving member is more stable.

  In addition, it can implement by forming in the surface of a magnetic adsorption type board the writing layer which can write in and erase | eliminate the felt pen which uses aqueous and / or alcoholic ink.

  And, in the accessory receiving part formed on the receiving member, a notch and / or a protrusion can be formed, and in this way, accessories such as rubber bands are also hooked, Convenience can be improved.

ADVANTAGE OF THE INVENTION According to this invention, although it is a simple structure, it can be finished in the magnetic adsorption type board with a receiving member with which the attachment strength of the receiving member was stabilized.
Therefore, the product can be finished as a product with high productivity and low production cost.
Further, since the receiving member is not directly fixed to the magnetic adsorption type board, the magnetic adsorption type board can also be used in a simple form without the receiving member.

  In addition, although the receiving member demonstrated so far is a thing with a comparatively large width dimension, naturally it is possible even if it is a narrow width, and the accessory receiving part was changed below. A description will be given including the form.

FIG. 8 basically shows a modification in which the width dimension is made smaller in the same cross section as the first embodiment, the first modification, the second modification, and the third modification described above.
That is, the receiving member 21 in FIG. 8A shows a modified example 5 in which the width of the first embodiment is about 1/2, and the receiving member 22 in FIG. 8B has a width of the modified example 1 of about 1/4. FIG. 8C shows a modified example 7 in which the width of the receiving member 23 in FIG. 8C is significantly reduced and the rising portion 23b of the accessory receiving part is also substantially triangular. The receiving member 24 of (d) shows a modification 8 in which the width of the modification 3 is significantly reduced.

  In addition, the receiving member of the present invention functions as long as the retaining portion is formed, and the accessory receiving portion can be implemented in a free form as long as it does not interfere with the insertion of the magnetic adsorption type board. it can.

FIG. 9 shows a modified example 9 showing an example thereof. FIG. 9 (a) is a perspective view, FIG. 9 (b) is a perspective view for explaining an assembly procedure, and FIG. 9 (c) is a ferromagnetic body. The perspective view of the article attachment state is shown.
That is, the receiving member 25 of this modification is formed of a substantially square retaining portion 27 and an accessory receiving portion 26 including a bottom portion 26a and a rising portion 26b in a form in which a round bar is bent.
Accordingly, the punched portion 4a of the magnetic adsorption type board 2a in that case is circular, and as shown in FIG. 9B, the tip of the accessory receiving portion 26 of the receiving member 25 with respect to the punched portion 4a. Can be attached to the ferromagnetic article W as shown in FIG. 9C.

  As described above, the shape of the accessory receiving portion of the receiving member can be freely deformed. In this case, the shape of the punched portion of the magnetic adsorption type board may be set to a shape along the shape.

10 and 11 (a) and 11 (b) show Example 2 of the present invention.
In this example, the magnetic attraction type board in Example 1 is made of a flexible magnet composite white board, but the configuration made of a hard cork board is different.
That is, a perspective view seen from the back side of the magnetic adsorption type board of FIG. 10, a perspective view showing the attachment state to the ferromagnetic article of FIG. 11A, and a partially enlarged longitudinal sectional view of FIG. Thus, the magnetic adsorption type board 31 with a receiving member is comprised by the magnetic adsorption type board 32 made from a cork board, and the receiving member 33 which took in many functions which are easy to suspend an accessory.

The magnetic adsorption type board 32 made of cork board has a base material 34 made of a wood board such as MDF having a thickness of about 5 to 10 mm, and a cork sheet 35 having a thickness of about 5 to 10 mm adhered with an adhesive, Magnets 36, 36,. . . Is attached with an adhesive.
At this time, the tip of the magnet 36 is set to a dimension that is slightly larger than the thickness of a retaining portion 39 of the receiving member 33 described later.
Further, similarly to the first embodiment, a punching portion 37 for inserting and locking a receiving member 33 described later is formed at the lower end portion.

  The receiving member 33 has basically the same configuration as that of the first embodiment, but the accessory used for the article is a key or the like suspended from a writing instrument such as a felt pen as in a white board. Since there are many applications, the upright portion 38b formed at the front portion of the bottom portion 38a of the accessory receiving portion 38 has hook portions 38c, 38c,. . . It is the structure which formed multiple.

The procedure of attaching the magnetic adsorption type board 31 with the receiving member of the second embodiment, which is configured as described above, to the ferromagnetic component W is generally the same as that of the first embodiment.
However, the hooks 38c, 38c,. . . Since the rising portion 38b is higher than the retaining portion 39, the receiving member 33 is easier to insert from the back side of the magnetic adsorption type board 32 in such a case.

Then, when the magnetic adsorption type board 32 that holds the receiving member 33 is magnetically attracted to the ferromagnetic article W, as shown in FIG. 11 (a), a perspective view showing the attachment state to the ferromagnetic article, the receiving member. The attached magnetic adsorption type board 31 is completed and attached.
At this time, in this embodiment, as shown in the partially enlarged longitudinal sectional view of FIG. 11B, the retaining portion 39 of the receiving member 33 is slightly between the magnetic adsorption type board 32 and the ferromagnetic article W. It is held in a state in which a gap is generated.
In addition, although there is some backlash by the gap, there is no problem in mounting strength.

The present invention can be implemented with various modifications.
For example, the magnetic adsorption type board is not limited to a white board using a felt pen or a cork board, as in the above-described embodiments, but is used for a magnetic adsorption board such as a blackboard or various bulletin boards using black ink It is possible to carry out by modifying it into a form suitable for the above.
At that time, as shown in the first and second embodiments, the magnetic adsorption type board can be implemented by either a flexible board or a hard board.
Various modifications of the receiving member shown in the first embodiment can naturally be used in the second embodiment, and can be further modified and implemented on the basis of them.

Although the present invention has a simple configuration with respect to the magnetic adsorption type board, the receiving member can be securely attached, and the receiving member can be easily removed. Therefore, convenience is high.
Moreover, as long as the board is magnetically attracted, it can be applied not only to the white board but also to various bulletin boards and the like, and the magnetic attracting board can be used from a flexible one to a hard one. .
Therefore, it can be used in a wide range of fields from general households to business use.
