Description

[Technical Field]

[0001] This invention relates to a clipboard that can prevent papers from falling out even when multiple papers are clamped in the clipboard. [Background technology]

[0002] A typical clipboard consists of a rigid board and a binding device attached to the board. By placing multiple pieces of paper between the binding devices, the board itself becomes a writing table, making it easy to carry and ideal for indoor and outdoor work. There are two types of commercially available clipboards: long-edge binding and short-edge binding.

[0003] Furthermore, prior art related to the clipboards mentioned above includes a multi-function clipboard that can store all the necessary stationery items and can also meet the various measurement requirements that arise during work (see, for example, Patent Document 1).

[0004] The multi-function clipboard of the above-mentioned Patent Document 1 is characterized in that it has a square underlay board with dimensional markings and a clamping clip means configured in the form of a box-shaped case, thereby having a stationery storage function. [Prior art documents] [Patent documents] [Patent Document 1] Utility Model Registration No. 3064003 Summary of the Invention [Problem to be solved by the invention]

[0005] The multi-function clipboard in the above-mentioned Patent Document 1 is said to be more convenient because it has a scale on the underlay board and a stationery storage function in the clip means. However, when multiple pieces of paper are clipped to the clip, the paper in the middle tends to fall out.

[0006] In view of the above, the present invention aims to provide a clipboard that can prevent the paper clipped by the binding device from falling out even when multiple pieces of paper are clamped.

[0007] In order to solve the above problem, a clipboard is provided which is composed of a board body, an attachment plate attached to the board body, and a binding device having a clip portion and a paper holding portion, and is characterized in that a base plate having a pair of protrusions is installed on the attachment plate.

[0008] The pair of protrusions are also positioned within the punched holes in the paper.

[0009] Furthermore, the substrate is mounted via a guide portion so that it can be raised and lowered freely.

[0010] By installing a base plate with a pair of protrusions on the mounting plate of the clipboard, punch holes are placed on the protrusions and the paper is clamped by the paper clamping part, thereby preventing the clamped paper from falling out.

[0011] Furthermore, by mounting the substrate having the convex portion in a freely undulating manner, when the substrate is moved, even paper without punched holes can be used as a commercially available clipboard. [Brief explanation of the drawings]

[0013] The clipboard of this invention is characterized by its ability to prevent the papers clamped by the binder from falling out even when multiple papers are clamped. The clipboard of the present invention will be described in detail below with reference to the drawings.

[0014] 1 and 2 is composed of a board body 2, a mounting plate 11 attached to the board body 2, and a binding device 10 having a clip portion 12 and a paper holding portion 13. In particular, the mounting plate 11 is provided with a base plate 20 having a pair of protrusions 21, 21'.

[0015] The board body 2 is made of a slightly thick paper board or plastic board. Although the board body 2 of the clipboard 1 of this invention is shown as a long-edge binding type in the drawings, it goes without saying that it is not limited to this and can also be used as a short-edge binding type.

[0016] The binding device 10 is composed of an attachment plate 11 attached to the board body 2 with rivets or the like, a semi-cylindrical clip portion 12 connected to one side of the attachment plate 11, and a paper clamp portion 13 that presses against the paper 3. The base end of the paper clamp portion 13 is connected to a biased state that presses against the paper 3 via a spring (not shown) inside the clip portion 12.

[0017] 3 shows the state in which paper 3 with pre-punched holes 4 is clamped in the clipboard 1 having the above-described configuration. First, the paper clamping section 13 is raised, and the punched holes 4 of the multiple layers of paper 3 are arranged between the pair of protrusions 21, 21'.

[0018] Next, after the stacked papers 3 are arranged, the paper holder 13 is laid down as shown in Figure 4. At this time, the paper holder 13 holds the side (top) of the paper 3 in a pressed state due to the spring's return force.

[0019] 5, the stacked multiple sheets of paper 3 are securely held by a pair of protrusions 21, 21' in the punched holes 4, preventing them from falling out of the binding device 10. Furthermore, even when used outdoors, the sheets of paper 3 will not shift or fall out.

[0020] As another preferred example, as shown in Fig. 6, a substrate 20 having a pair of protrusions 21, 21' may be mounted so as to be able to rise and fall freely via guide portions 22, 22'. The guide portions 22, 22' are ring-shaped and are mounted so as to penetrate the substrate 20, the mounting plate 11, and the board body 2.

[0021] With the above-described configuration, the substrate 20 can be moved to the clip 12 side via the guide portions 22, 22' as shown in Fig. 7. As a result, the binding device 10 can be used in the same way as a commercially available clipboard as shown in Figs. 8 and 9.

[0022] Figure 10 shows a front view of the substrate 20 placed on the mounting plate 11, and Figure 11 shows a front view of the paper 3 with pre-punched holes 4 set on the board body 2.

[0023] Figure 12 is a side view of the state in which the substrate 20 has been moved toward the clip 12, Figure 13 is a side view of the state in which the substrate 20 has been moved toward the mounting plate 11, and Figure 14 shows the state in which the punch holes 4 in the paper 3 are placed on a pair of protrusions 21, 21' and the paper 3 is clamped by the paper clamping section 13.

[0024] With the above-described configuration and method of use, by moving the board 20 toward the clip 12 via the guide portions 22, 22', it is possible to clip the paper 3 in the same way as with a commonly used commercially available clipboard.

[0025] Furthermore, by moving the base plate 20 to the mounting plate 11, the punch holes 4 of the paper 3 that have been punched can be positioned on the protrusions 21, 21', and multiple stacks of paper 3 can be firmly clamped to the binding device 10.

[0026] This prevents multiple stacked papers 3 from falling out, and even when used outdoors in strong winds, the papers 3 will not fall off the clipboard 1. Furthermore, the punched holes 4 for the papers 3 are arranged in the protrusions 21, 21', preventing the stacked papers 3 from shifting. [Explanation of symbols]
