Description

[Detailed description of the invention] This proposal relates to the attachment of the frame to the main body without using screws, etc., and the structure in which the writing board is completely sandwiched and fixed between the main body and the frame. It is something.

Conventionally, in a structure in which a writing board is sandwiched and fixed using a main body and a frame, the bullet pieces of the frame are inserted into the notches of the main body and fixed, but the bullet pieces of the frame protrude from the main body and the main body There is a drawback that when handling the bullet, one's hands touch the protruding part of the bullet and become uncomfortable, and there is also a risk that the bullet will separate from the main body, causing the body and frame to separate.

This proposal improves this drawback.

In other words, the cross-section mold engagement part protrudes outward from the upright piece of the frame, and the bottom plate is connected to the upright piece of the main body, and the bullet piece is inserted into the bottom plate. Along with providing a notch,
A holding part is provided on the upright piece located in the notch and is recessed from the surface of the bottom plate to a thickness greater than at least the thickness of the engaging part, and the elastic piece of the frame is inserted into the notch of the main body, and the engaging part of the elastic piece is inserted into the main body. The attachment of the main body and the frame, engaged with the holding portion of the upright piece, is a structure.

The feature of this project is that there is a notch in the bottom plate of the main body, and
A holding part is provided on the upright piece located in the notch and is recessed from the surface of the bottom plate at least more than the thickness of the engaging part of the elastic piece of the frame body.

Therefore, in a state where the engaging portion of the elastic piece of the frame is engaged with the holding portion of the upright piece of the main body, the engaging portion of the elastic piece is flush with the surface of the bottom plate of the main body or in a recessed position, Even if your hand touches the engaging part of the bullet, you will not hesitate, and furthermore, the engaging part will not disengage.

Therefore, the writing board, which is sandwiched and fixed between the main body and the frame, does not come off at all.

There are various types of writing boards used in this project, including magnetic panels, whiteboards, and crayon boards.

A magnetic panel is a plastic dispersion liquid consisting of magnetic fine particles, a dispersion medium, a fine particle thickener, and optionally a coloring agent sealed between two substrates, and is plastically dispersed when a magnetic force is applied from the front substrate side with a magnetic pen. The magnetic particles in the liquid are attracted to the front substrate and form a display.Next, when a magnetic force is applied using an erasing magnet from the back substrate side, the magnetic particles forming the display are attracted to the back substrate and the display is erased. will be deleted.

An embodiment of the present invention will be explained with reference to the drawings.

The frame 1 has a rectangular outer shape, and on each side of the upright piece 2, a bullet piece 5 with a cross section of ■7 shape (Fig. 8) is formed by pairs of notches 3, with an engaging portion 4 protruding from the upright piece 2. There are two of each.

The main body 6 has a rectangular outer shape, and the inner wall of the upright piece 7 is shaped so that the outer wall of the upright piece 2 of the frame body 1 is in close contact with the bottom plate 8 connected to the upright piece 7. Eight notches 9 into which bullets 5 can be inserted are provided corresponding to all of the bullet pieces 5,
A holding part 10 is provided in the notch 9 and recessed in the upright piece 7 by a dimension equal to the thickness of the engaging part 4 of the elastic piece 5.

The writing board 11 is the aforementioned magnetic panel, has a rectangular shape that can be inserted into the main body 6, and is placed on the bottom plate 8 of the main body 6, and is positioned by a projection 12 provided on the bottom plate 8.

To assemble the main body 6 and the frame 1, first insert the writing board 11 into the main body 6 and place it on the bottom plate 8.

Next, the frame 1 is inserted into the main body 6.

At this time, the engaging portions 4 of all the bullets 15 are connected to the upright piece 7 of the main body 6.
so that it hits the inner wall of the

Since the bullet piece 5 is elastic, it moves inward of the frame body 1.

When the frame body 1 is moved toward the writing board 11, the engaging portion 4 of the bullet piece 5
slides on the inner wall of the upright piece 7 of the main body 6 and enters the notch 9 of the bottom plate 8.
The bullet pieces 5 are moved by external force, and the engaging portion 4 engages with the holding portion 10 of the upright piece 7 of the main body 6 flush with the bottom plate 8 and is fixed (FIG. 8).

At the same time, the upright piece 2 of the frame 1 presses and fixes the writing board 11.

The writing board 11 attached to the main body 6 is, as described above, written on the front substrate of the writing board 11 using a magnet ben (not shown) to form a display.The writing board 11 is erased from the back side of the main body 6 by magnetic force (not shown). to display and erase the display.

When fixing the writing board 11 between the main body 6 and the frame 1,
The four sides of frame 1! : It is sufficient to provide one or several bullet pieces 5 per side, provide corresponding notches 9 in the main body 6, and assemble the main body 6 and the frame 1.

In addition, a protrusion 12 (FIG. 9) is provided on only one side of the frame 1, one or several bullet pieces are provided on the other three sides, and the main body 6 has a hole into which the protrusion 12 is inserted. 13 (Figure 9),
Furthermore, a notch into which the bullet piece is inserted is provided, and the protrusion 1 of the frame body 1 is
2 into the hole 13 of the main body 6, and the bullet piece is inserted into the notch and engaged with the holding part of the upright piece as described above to attach the main body 6 and the frame 1, and sandwich the writing plate 11. It may also be fixed.

In this case, the main body and the frame that sandwich the writing board from above and below can be easily attached, and the engaging part of the bullet of the frame is flush with the surface of the bottom plate of the main body, or is recessed from the surface of the bottom of the main body. Since it engages with the holding part of the upright piece, you won't have to worry about touching the holding part of the bullet piece when handling the main body, and furthermore, you won't have to disengage the holding part of the bullet piece, so you can write easily. The board is securely fixed.
