Abstract

PROBLEM TO BE SOLVED: To eliminate protrusion of the clipping portion of a clip board, which frequently causes hindrance, thereby enhancing the convenience and storage property.SOLUTION: The clip board has a leaf spring provided on the upper back face thereof. The clip board has a paper insertion groove on the upper front face or the clip board has a leaf spring clip that enables forming the paper insertion groove on the upper end thereof. By flexing the upper of the clip board toward the back face side, the paper insertion groove is widen, into which paper is inserted, allowing the paper and the clip board to make a flat surface.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a clipboard (similar to a drawing board) used for writing with a sheet interposed therebetween.

The normal clipboard is provided with a clip for sandwiching paper at the top of the board. The size is adapted to general paper such as A4 and B4, for example, and the clip is attached according to the vertical type and the horizontal type.
Further, according to Patent Document 1, as a special one, the clip upper surface side is also slid by the number of sheets (thickness) to be clamped so that the clip clamping surface is in close contact, and the clip is less likely to be affected during storage. ing. According to Patent Document 2, when another sheet is added in a state where one sheet is sandwiched between the clipboards, the first sheet is easily displaced, so the first sheet is a method for preventing this. The form which provided the projection part so that it may not enter into the back above is indicated.

  The clipboard according to the present invention is different from the above-mentioned patent document, and the purpose is to write only with one sheet of paper, and the problem is to eliminate the protrusion as a clip.

  Briefly, the structure is a single thick (e.g., 7 millimeter thick) flexible board without clips, which is lined horizontally above the board, i.e., in a location to provide a clip. A cut is made, and the cut is opened by pressing and curving from the lower surface side, the paper is sandwiched there, and the paper is fixed by returning the board board to its original position.

  The purpose (necessity) of eliminating the protrusion of the clip is easy to handle because the ruler does not hit the clip. This is especially important when drawing diagrams. In addition, since most of the upper area of the sheet is not sandwiched, it is easy to describe the top. Furthermore, this shape is very advantageous for storage and suitable for carrying.

A plan view of a clipboard integrated board or back plate spring type according to the present invention. Rear view with back leaf spring type Enlarged view of the center cross-section with integrated board Enlarged view of the center section of the back leaf spring when flat Enlarged view of the center cross section of the back leaf spring when bent Plan view with leaf spring clip type Rear view with leaf spring clip type Enlarged view of the center cross section when the leaf spring clip is flat Enlarged view of the center section when the leaf spring clip is bent Plan view by slide clip type Rear view with slide clip Enlarged view of the central section of the slide clip type Enlarged view of the center section when inserting paper with a slide clip type Uniform gap groove shape Inclined upper contact groove shape

  The board integrated type will be described with reference to FIG. 1 and FIG. 3. A single thick board, for example, a hard rubber plate having a thickness of 7 mm, is used, and a notch for sandwiching a sheet is formed into a sheet insertion groove (2 ). FIG. 3 is a cross-sectional view, but when the paper is inserted, the board body easily breaks in the extension of the paper insertion groove (2) as shown in FIG. 5, and therefore it is preferable to provide the reinforcing plate (3). The material is not limited as long as it is thin, strong, and flexible, whether it is cloth or leather. As shown below, the board-integrated clipboard has a high risk of damage, and because it is thick, it is difficult to write if the hand position is removed from the clipboard during writing.

  Therefore, the back plate spring type will be described as a thin clipboard. According to FIG. 2, a leaf spring (4) is provided only at the upper part of the back surface. As can be seen from FIGS. 4 and 5, the sheet is bent by a finger and inserted into the sheet insertion groove (2). In this cross-sectional view, the leaf spring (4) is incorporated in the board body (1a), but the thickness of the leaf spring (4) is very thin, and even if the shape is affixed, there is a step. It does not hinder use, and is considered advantageous in terms of cost. The material of the board body (1a) is not particularly limited.

  The board body clip portion (1b) shown in FIGS. 1 and 2 does not need all the shapes shown in the drawings, and only needs to be able to sandwich paper, and can have the shape 1b (5) shown in FIG. In FIGS. 8 and 9, the sheet is sandwiched between the protrusion of the leaf spring clip (5) and the end of the board body (1a). When it uses frequently here, the edge part (equivalent to 6b) of a leaf | plate spring clip (5) adhesion surface (6a) becomes easy to peel. Therefore, it is possible to prevent damage by joining the end portions with screws (6b). Moreover, this leaf | plate spring clip (5) may just stick on a back surface like the above, without incorporating in a board body (1a).

  Next, a description will be given based on FIGS. 10 to 13. This form does not curve the board body, but is a method of holding the paper by sliding the slide clip (7 a). Therefore, when the board body (1a) and the slide clip (7a) shown in FIG. 12 are in close contact with each other, it is preferable to include a biasing means for sandwiching the paper. The slide clip (7a) is slid by a slide rail (7c) provided on the back surface of the board body (1a), and is opened and closed using the claw hook (7b).

  Considering the state where the paper is sandwiched, first, when the width of the paper insertion groove (2) is not large, that is, in the shape without the width of (2) in FIG. 3, the paper cannot be inserted accurately to the back. However, in this case, the paper is sufficiently pressed and the paper is not easily displaced during writing. On the other hand, when the paper insertion groove (2) has a width as shown in FIG. 14, the paper is likely to enter deeply, but the paper is likely to slip during writing and may come off. Therefore, by forming the sheet insertion groove (2) in the shape of an inclined upper contact groove as shown in FIG.

  Next, the sheet insertion groove (2) is provided at an angle between 0 and 90 degrees. However, the smaller the angle (closer to 0 degree), the more unstable the sheet and the easier it is to come off. Conversely, the larger the angle (closer to 90 degrees), the more stable and harder the paper is to come off. However, if the sheet is sandwiched in a state where the angle is large, the sheet is raised immediately in the vicinity of the sheet insertion groove (2), which causes troubles during writing. On the other hand, it may be possible to solve this problem by pressing it with your hand when writing. However, as a reliable method, although the paper will be slightly folded along the paper insertion groove (2), The board body (1a) will be in close contact.

  In view of these, the curved shape of the slide clip (7a) according to FIGS. 12 and 13 has an effect of preventing the sheet from rising. Further, if the slide clip (7a) has a shape that also covers the upper surface of the board body (1a), the sheet can be prevented from rising, but it is inferior in the case of using a ruler that is an essential requirement of the present invention. However, there are other prevention methods, so it is inevitable.
