Description

[Detailed Description of the Invention] Technical Field This invention relates to a writing board from which characters written on the top surface can be easily erased, and particularly relates to a holding structure for hanging and holding the writing instrument.

BACKGROUND ART Conventionally, in this type of writing board, a saucer was provided at the lower edge of the writing board, for example, in order to accommodate and hold a pen used on the writing board. When the pen was not in use, it was placed on a saucer. However, in this conventional configuration, when the writing board is used while being suspended from a wall, there is a risk that the writing instrument will easily fall off the tray and be lost. There is also a writing board in which an iron plate is used for the writing board body and a permanent magnet is fixed to the pen so that the pen can be attracted and held on the writing board by the permanent magnet. However, in this configuration as well, as with the conventional configuration, there is a risk that the pen may easily fall off the writing board due to vibrations applied to the writing board.

Purpose This invention was made to eliminate the above-mentioned defects, and its purpose is to easily and reliably hold a writing instrument on a writing board.
Moreover, it is an object of the present invention to provide a holding structure for a writing instrument or the like on a writing board that has a simple structure.

Embodiment An embodiment embodying this invention will be described below with reference to FIGS. 1 to 12. Writing board frame 1
is made of a sheet material made of synthetic resin, and has a pair of hooks 2 protruding from its upper edge.
The hook 2 allows the writing board to be hung on a wall or the like. A shallow groove-shaped recess 3 is formed in the center of the frame 1, and within the recess 3 is a writing board body 4 with paint baked onto the top surface of an iron plate.
is accommodated and fixed with adhesive or the like.
The writing instrument used for this writing board is a water-based ink pen 5, and the pen has a round bar shape. A cylindrical cap 5a is inserted into the pen tip, and an erasing body 6 having an erasing section made of felt material is removably inserted into the cap 5a.

A pair of accommodating portions 7 are formed at the lower end of the frame 1, and each accommodating portion 7 is opened at the surface of the frame 1. The left accommodating portion 7 has a narrow portion and a wide portion having substantially the same external shapes as the water-based ink pen 5 and the eraser 6. Further, the right housing portion 7 does not have a wide portion. and,
Each housing portion 7 can accommodate a water-based ink pen 5 and an eraser 6. A pair of latching protrusions 9 as latching members are provided on the opening peripheries of the accommodating portions 7 facing each other in the narrow width portions of the accommodating portions 7.
It is integrally formed to protrude inward. Therefore, when storing the water-based ink pen 5 without the eraser 6 in the right housing part 7 when the writing board is not in use, the water-based ink pen 5 is stored in the right housing part 7.
If you press from the opening periphery towards the bottom side of the housing part 7,
The outer peripheral surface of the water-based ink pen 5 is engaged with each of the locking protrusions 9.

Then, by further continuing the pressing operation, the opening of the accommodating part 7 is expanded against the elastic force of the frame 1 itself, and when the water-based ink pen 5 is engaged with the bottom of the accommodating part 7, the opening of the accommodating part 7 is expanded. Due to the elastic restoring force of the frame body 1, the opening of the accommodating part 7 is restored to its original state, and the locking protrusion 9 is engaged with the outer peripheral surface of the water-based ink pen 5, so that the pen 5 is inserted into the accommodating part 7. It is securely locked inside. Therefore, even if the writing board is inadvertently vibrated in this state, there is no possibility that the water-based ink pen 5 will fall out of the housing portion 7. Further, in the left storage section 7, both the water-based ink pens 5 and 6 are stored in the same manner as described above, with the eraser 6 attached to the cap 5a of the water-based ink pen 5. Further, the water-based ink pen 5 is placed in the housing portion 7.
When removing the water-based ink pen 5 , insert your finger into the finger-holding recess 8 and grasp the water-based ink pen 5 against the elastic holding force of the latching protrusion 9 .
It can be easily removed by pulling it forward.

In this embodiment, since date numbers N from 1 to 31 and ruled lines L corresponding to the numbers N are provided on the surface of the writing board main body 4, the water-based ink pen 5 is used to draw along the ruled lines L. You can write down your schedule for one month, etc. Moreover, each time the month changes, the memo can be easily erased using the erasing portion of the erasing body 6, and the schedule corresponding to the new month can be written again using the water-based ink pen 5.

Next, a method for manufacturing this writing board will be explained.
The frame 1 of this writing board is formed by a so-called vacuum forming method. In this vacuum forming method, a suitably heated sheet material made of styrene or the like is placed on a mold, and then the air between the mold and the sheet material is released to the outside using a vacuum pump or the like. As a result, the sheet-like material is brought into close contact with the shape of the mold, and the sheet-like material is molded according to the shape of the mold. By forcedly cooling the sheet material, the molded sheet material can be separated from the mold. In this embodiment, the mold 10 is provided with a plurality of undercut portions 11 corresponding to the locking projections 9. Normally, when the mold 10 is provided with an undercut portion 11, it is difficult to separate the product from the mold 10, but in this embodiment, when the sheet material is forcedly cooled, the sheet material is contracted, and the inner wall of the accommodating portion 7 becomes the undercut portion 1.
1, the sheet material can be easily separated.

Another Embodiment Next, another embodiment will be described, focusing on the differences from the previous embodiment. Now, in this example, the first
As shown in FIG. 3, an inclined guide surface 9a is formed on the surface of the locking projection 9. Therefore, when the writing instrument 12, which is different from the water-based ink pen 5 and has a substantially rectangular cross section, is housed in the storage portion 7, the writing instrument 12 is brought into contact with the inclined guide surface 9a of the latch projection 9. When the writing instrument 12 is pressed toward the bottom side of the accommodating portion 7, the writing instrument 12 is pushed onto the inclined guide surface 9a.
, and is introduced into the accommodating portion 7 against the elastic force of the latching protrusion 9 . When the writing instrument 12 is housed in the accommodating portion 7, the latching protrusion 9 engages with the upper surface of the writing instrument 12, and the writing instrument 12 is reliably latched and held within the accommodating portion 7.

Moreover, when removing the writing instrument 12 from the storage part 7, insert a finger into the finger rest recess 8, grasp the writing instrument 12, and pull out the writing instrument 12 forward against the elastic force of the frame 1. It can be easily removed.

Note that this invention is not limited to the above-mentioned embodiments; for example, the latching protrusions may be arranged slightly shifted to the left or right, or a plurality of latching protrusions may be provided only on the periphery of the opening on the upper or lower side of the accommodating portion 7. The hook may be configured so that a writing instrument is held between the latch projection and the inner wall of the accommodating portion 7, or a pointing rod or a conductor baton that can be freely expanded and contracted in the longitudinal direction can be accommodated in the accommodating portion. It is also possible to arbitrarily change the structure of each part without departing from the spirit of this invention, such as by providing a protrusion extending along the opening periphery instead of the stop protrusion.

Effects As detailed above, this invention integrally forms a concave accommodating portion for accommodating the entire object to be accommodated, such as a writing instrument, on the surface of the writing board frame formed of a synthetic resin material, and A pair of locking members for locking the stored object in the stored state are integrally formed on the opening periphery of the inner surface of the storage portion so as to face each other and protrude into the storage portion, thereby achieving the following unique effects. It is something that plays.

(b) In the accommodated state, the objects 5 and 12 are completely accommodated in the accommodation section 7, and the writing board frame 1
Since the objects 5 and 12 do not protrude from the surface of the storage part 7 and are locked by the locking member 9,
securely held within.

Therefore, when using the writing board of the present invention by hanging it on a wall or the like, there is no risk of the user or the like hitting the objects 5, 12 and dropping them.

(b) When forming the accommodating portion 7 in the writing board frame 1,
There is no need to add any new members, and since the accommodating portion 7 and the hanging member 9 do not protrude from the surface of the writing board frame 1, when the writing board of the present invention is hung on a wall etc. as described above, When the user or the like collides with the housing part 7 and the hooking member 9, these housing parts 7
Also, there is no risk of damaging the hooking member 9. Therefore, the accommodation portion 7 and the hanging member 9 will not be damaged and the objects 5 and 12 will not be able to be accommodated. Furthermore, it does not become bulky even when a large number of writing boards of the present invention are stacked during transportation.
