[0014] An embodiment of the present invention will now be described with reference to Figures 1 to 16. Note that the vertical and horizontal directions in this embodiment are set for the convenience of explanation.

[0015] In this embodiment, the present invention is applied to a clipboard in which the size of the portion that can serve as a backing for document P can be changed by folding the portion that can serve as a backing for document P in half.

[0016] The clipboard comprises a clipboard body A having a bent part H located in the vertical center and extending in the left-right direction, a single clip B provided on the clipboard body A and capable of holding a document P, and a storage pocket C provided on the back side of the clipboard body A.

[0017] As shown in Fig. 5(a), the clipboard can be configured to form a clipboard body A in which the first board 1 and the second board 2 together form an area that can serve as a backing base suitable for an A3-sized document P by placing the second board 2 in the unfolded position (T). Also, as shown in Fig. 5(b), the clipboard can be configured to form a clipboard body A in which the second board 2 is the main body and forms an area that can serve as a backing base suitable for an A4-sized document P by placing the second board 2 in the folded position (M).

[0018] That is, the clipboard of this embodiment is configured to be flexibly usable by clipping documents P of different sizes, such as A3 size and A4 size, onto a common clip B provided on the first board 1.

[0019] The clipboard can be made compact as a whole, making it easy to carry, by folding the second board 2 into the folded position (M).

[0020] The clipboard will be described in detail below.

[0021] <<Clipboard Body A>> The clipboard body A comprises a first board 1 having a single clip B arranged in the center of the upper end of the front side in the left-right direction, and a second board 2 connected to the lower end of the first board 1 via a bending portion H.

[0022] <First Board 1> The first board 1 comprises a first front board material 1F having a horizontally elongated, approximately rectangular shape, and a first back board material 1R having a horizontally elongated, approximately rectangular shape and attached to the back side of the first front board material 1F.

[0023] The thickness w2 of the first back board material 1R is set to be longer than the thickness w1 of the first front board material 1F. The first back board material 1R has a rigidity that allows almost no bending deformation in the thickness direction, while the first front board material 1F allows slight bending deformation in the thickness direction only when it receives a relatively strong load.

[0024] The vertical dimension w3 of the first front board material 1F is set longer than the vertical dimension w4 of the first back board material 1R. The upper edge of the first front board material 1F and the upper edge of the first back board material 1R are set to be approximately aligned. A first extension portion 11 is provided at the lower end of the first front board material 1F, extending in a cantilevered manner downward from the lower edge e1 of the first back board material 1R.

[0025] The first front board material 1F and the first back board material 1R are each made of synthetic resin. The first front board material 1F and the first back board material 1R are bonded to each other by spot welding their peripheral edges at multiple locations. In other words, the rear surface of the first front board material 1F, excluding the first extension portion 11, is bonded to almost the entire front surface of the first back board material 1F. In the drawings, the spot-welded portions are indicated by the symbol i.

[0026] The first board 1 has through holes 12 at the upper left and right corners for inserting shoulder straps.

[0027] Recesses 13 capable of receiving both left and right ends of the storage pocket C are formed in the vertical center of the left and right outer edges of the first board 1. The recesses 13 are longitudinal in the vertical direction and are provided in pairs on the left and right sides of the first board 1. The recesses 13 are composed of front recesses 13f provided at both left and right ends of the first front board material 1F and rear recesses 13r provided at both left and right ends of the first rear board material 1R.

[0028] In this embodiment, the degree of inward recession of the front recess 13f is set to be greater than the degree of inward recession of the back recess 13r. The front recess 13f is recessed more inward than the back recess 13r in the first back board material 1R, i.e., toward the left-right center of the first board 1. By setting the recessions of the front recess 13f and the back recess 13r in this manner, the welded portions 8 provided at both left and right ends of the storage pocket C can be welded to the front surface of the first back board material 1R exposed by the front recess 13f after wrapping around the left and right outer edges corresponding to the back recess 13r in the first back board material 1R.

[0029] <Second Board 2> The second board 2 comprises a second front board material 2F having a horizontally elongated, approximately rectangular shape, and a second back board material 2R having a horizontally elongated, approximately rectangular shape, attached to the back side of the second front board material 2F.

[0030] The thickness w6 of the second back board material 2R is set to be longer than the thickness w5 of the second front board material 2F. The second back board material 2R has a rigidity that allows almost no bending deformation in the thickness direction, while the second front board material 2F is allowed to bend slightly in the thickness direction when subjected to a load.

[0031] The thickness w5 of the second front board 2F is set to be approximately the same as the thickness w1 of the first front board 1F. Similarly, the thickness w6 of the second back board 2R is set to be approximately the same as the thickness w2 of the first back board 1R.

[0032] The second front board material 2F is formed integrally with the first front board material 1F via a bent portion H that extends linearly in the left-right direction. In other words, the first and second front board materials 1F, 2F are integrally connected via the bent portion H. As shown in FIG. 9, the first and second front board materials 1F, 2F and the single bent portion H interposed therebetween are formed on a single board material made of synthetic resin.

[0033] The vertical dimension w7 of the second front board material 2F is set shorter than the vertical dimension w8 of the second back board material 2R. The lower edge of the second front board material 2F and the lower edge of the second back board material 2R are set to be positioned substantially aligned. A second extension portion 21 is provided at the upper end of the second back board material 2R, extending in a cantilevered manner above the upper edge of the second front board material 2F.

[0034] The second front board material 2F and the second back board material 2R are each made of synthetic resin. The second front board material 2F and the second back board material 2R are bonded to each other by spot welding their peripheral edges at multiple locations. In other words, almost the entire rear surface of the second front board material 2F is bonded to the front surface of the second back board material 2R, excluding the second extension portion 21. In the drawings, the spot-welded portion is indicated by the symbol i.

[0035] The second board 2 has through holes 22 at the left and right lower corners for inserting shoulder straps.

[0036] The second board 2 is provided with a fastening band J that extends in the left-right direction and holds the document P against the surface of the second board 2. Anti-slip members k are provided at both ends of the fastening band J. The anti-slip members k are inserted from the front side toward the rear side into mounting holes 23 drilled at both left and right ends of the second board 2, and engage with the rear side of the second board 2.

[0037] The fastening band J has the function of preventing documents P (e.g., A3 size) placed on the clipboard body A in the unfolded position (T) from being turned over by the wind outdoors, for example. By engaging the fastening band J with the first board 1 so as to surround the rear and both sides of the first board 1, the folded position (M) of the second board 2 can be stably maintained.

[0038] The second board 2 can take an unfolded position (T) in which it can, together with the first board 1, form a continuous base for the document P, i.e., a base for an A3-sized document P held by the clip B, and a folded position (M) in which it can be folded at the folding portion H (using the folding portion H as the center of rotation) onto the surface side of the first board 1 to form a base for the document P, i.e., a base for an A4-sized document P held by the clip B, and does not interfere with the clip B.

[0039] The second board 2 is sized so that it does not interfere with the clamping member b2 of the clip B in the folded position (M). The second board 2 is set so that the upper edge e2 in the folded position (M) is positioned below the clip B.

[0040] That is, in the folded position (M), the upper edge e2 of the second board 2 is set to be separated from the clamping member b2 of the clip B. In other words, the clipboard is configured so that the second board 2 can change its position between the folded position (M) and the unfolded position (T) while the clip B remains clamping the document P.

[0041] The second board 2 is configured such that, in the unfolded position (T), the outer surface of the second front board material 2F faces forward to serve as a backing for the documents P. On the other hand, in the folded position (M), the second board 2 is configured such that the outer surface of the second back board material 2R faces forward to serve as a backing for the documents P, and the outer surface of the second front board material 2F faces backward to face the front surface of the first board 1.

[0042] In this embodiment, when the second board 2 is in the unfolded position (T), the first end face t1, which is the lower end face of the first back board material 1R, and the second end face t2, which is the upper end face of the second back board material 2R, can face each other and abut against each other.

[0043] The first and second boards 1, 2 are configured such that, in the deployed position (T), the first end surface t1 and the second end surface t2 abut against each other over substantially the entire surface.

[0044] In this embodiment, both the first end face t1 of the first back board material 1R and the second end face t2 of the second back board material 2R are inclined. The first end face t1 is inclined with respect to the thickness-direction center line c1 of the first back board material 1R. The second end face t2 is inclined with respect to the thickness-direction center line c2 of the second back board material 2R.

[0045] More specifically, both the first end face t1 and the second end face t2 are inclined so that, when viewed with the thickness direction center lines c1 and c2 as the horizontal reference, they gradually move outward in a downward direction, i.e., away from the first and second surface board materials 1F and 2F.

[0046] In addition, the angle α of the second board 2 relative to the first board 1 in the unfolded position (T) is restricted to an angle of less than 180°. Note that if the second board 2 in the unfolded position (T) is excessively bent relative to the first board 1, writing performance will be impaired, so it is desirable that the angle α of the second board 2 in the unfolded position (T) relative to the first board 1 be set within the range of 170° to less than 180°.

[0047] By setting the angle α in the unfolded position (T) to less than 180° in this manner, the second board 2 in the unfolded position (T) is less likely to sag downward from the horizontal line of the first board 1 (a line that approximately coincides with the thickness-wise center line c1 of the first backing board material 1R) even if bending deformation of the component occurs, thereby providing excellent writing properties for documents P placed on the second board 2.

[0048] <Clip B> Clip B is used to clamp document P. Clip B includes a base member b1 made of a metal plate and attached to first board 1, and a clamping member b2 formed by bending a metal rod and rotatably supported on base member b1.

[0049] The clamping member b2 is capable of clamping a document P between itself and the base member b1. A spring G is interposed between the clamping member b2 and the base member b1, and the clamping portion b21 at the tip end of the clamping member b2, which extends in the left-right direction, is biased toward the base member b1 so as to clamp the document P.

[0050] The base member b1 has a substantially rectangular shape when viewed from the front. The base member b1 is attached to the first board 1 by a rivet V, which is a fastener. The first board 1 is provided with a hole 14 through which the rivet V passes.

[0051] A raised portion b11 is formed on the base member b1 at a position adjacent to the tip clamping portion b21 of the clamping member b2. The raised portion b11 is provided at a position below and away from the tip clamping portion b21 of the clamping member b2. The raised portion b11 is provided on the lower end portion of the base member b1. The raised portion b11 is capable of smoothly guiding the document P clamped between the tip clamping portion b21 and the base member b1 to the front surface of the second board 2 in the folded position (M).

[0052] <Storage pocket C> The storage pocket C can form an upwardly open storage space sp between itself and the first backboard material 1R, in which documents P and clear folders can be stored. The storage pocket C is made from a single sheet of synthetic resin material.

[0053] The storage pocket C comprises a pocket body 3 having a generally rectangular shape and a left-right dimension w10 set to be generally the same as the left-right dimension w9 of the longest part of the first board 1; a flap portion 4 extending upward from the upper edge of the pocket body 3 via a fold line n1; a lower gusset portion 5 extending outward from the lower edge of the pocket body 3 via a fold line n2; a lower welded portion 6 extending outward from the outer edge of the lower gusset portion 5 via a fold line n3 and welded to the lower rear surface of the first back board 1R; left and right gusset portions 7 extending outward from both the left and right side edges of the pocket body 3 via a fold line n4; and left and right welded portions 8 extending outward from the outer edges of the left and right gusset portions 7 via a fold line n5 and welded to the front surface of the first back board 1R exposed by the front recess 13f in the first front board material 1F.

[0054] The left-right dimension w10 of the pocket body 3 is approximately the same as the left-right dimension w9 of the longest part of the first board 1. By setting the left-right dimension w10 of the pocket body 3 in this way, it is easy to obtain the longest possible interior dimension that can accommodate clear folders in the storage space sp, and it also makes it easy to maintain a width that can be accommodated in a typical wagon drawer.

[0055] A fold line 5c that forms the lower edge of the storage pocket C is provided in the center of the lower gusset portion 5 in the width direction.

[0056] The width dimension w11 of the left and right gusset portions 7 is set to be larger than the thickness dimension w6 of the first back board material 1R. By configuring it in this way, a storage space sp can be easily formed between the pocket body 3 and the first back board material 1R.

[0057] The left and right gusset portions 7 and the left and right welded portions 8, which are the left and right side ends of the storage pocket C, wrap around the left and right side edges, which are the outer edges of the first board 1 of the clipboard main body A, from the back side to the front side. The left and right welded portions 8 are fixed to the front side of the first board 1 of the clipboard main body A by welding. The left and right gusset portions 7 extend in the front-to-rear direction, which is approximately perpendicular to the pocket main body 3, and are configured so that part of the left and right gusset portions 7 are located within the recessed portion 13 of the first board 1.

[0058] The process of attaching the storage pocket C will be described with particular reference to FIGS.

[0059] First, as shown in Fig. 13, a first back board material 1R to which the storage pocket C is attached is prepared. At this stage, the first back board material 1R is attached to the first front board material 1F by spot welding.

[0060] Next, as shown in Figure 14, the lower welded portion 6 of the storage pocket C is welded to the outer surface of the lower end of the first back board material 1R. The lower welded portion 6 is aligned so that the fold line 5c of the lower gusset portion 5 approximately coincides with the lower edge e1 of the first back board material 1R, and then welded to the first back board material 1R.

[0061] Next, as shown in FIG. 15, the pocket body 3 is moved toward the outer surface of the first back board material 1R with the folding line 5c as the center of rotation.

[0062] 16, the left and right gusset portions 7 and the left and right welded portions 8 are fitted around the rear recess 13r, which is the outer edge of the first back board material 1R, and then the left and right welded portions 8 are welded to the front surface of the first back board material 1R. The front recess 13f provided in the first front board material 1F is designed not to interfere with the left and right welded portions 8. This makes it difficult for the left and right welded portions 8 to form convex or raised portions on the front side of the first board 1 that would interfere with writing or impair the folded position (M) of the second board 2.

[0063] As explained above, the clipboard according to this embodiment comprises a clipboard body A having a folding portion H, and clips B attached to the clipboard body A and capable of holding documents P. The clipboard body A comprises a first board 1 having clips B arranged on its front side, and a second board 2 connected to the first board 1 via the folding portion H. The second board 2 can take an unfolded position (T) in which it can form a continuous platform for documents P together with the first board 1, and a folded position (M) in which it is folded toward the front side of the first board 1 around the folding portion H as the center of rotation, forming a platform for documents P and not interfering with the clips B.

[0064] Therefore, it is possible to provide a clipboard that can be flexibly used by clipping documents P of different sizes, such as A3 size and A4 size, onto the clip B.

[0065] The clip B comprises a base member b1 attached to the first board 1 and a clamping member b2 provided on the base member b1, and the base member b1 has a raised portion b11 provided at a position adjacent to the clamping member b2.

[0066] Therefore, the document P held by the clip B can be suitably guided to the outer surface of the second board 2 in the folded position (M) by utilizing the raised portion b11.

[0067] The edge of the second board 2 is set to be spaced apart from the clamping member b2 in the folded position (M), and the second board 2 is configured to be able to change its position between the folded position (M) and the unfolded position (T) while the clip B remains clamping the document P.

[0068] As a result, the document P held by the clip B is unlikely to interfere with the upper edge of the second board 2 in the folded position (M), and the second board 2 can be flexibly changed between the folded position (M) and the unfolded position (T) while the document P remains held by the clip B.

[0069] The first board 1 comprises a substantially rectangular first front board material 1F and a substantially rectangular first back board material 1R attached to the back side of the first front board material 1F. The second board 2 comprises a substantially rectangular second front board material 2F and a substantially rectangular second back board material 2R attached to the back side of the second front board material 2F. The first front board material 1F and the second front board material 2F are connected together via a bent portion H.

[0070] Therefore, when the second board 2 is in the deployed position (T), it can be configured to be approximately flush with the front surface of the first board 1.

[0071] The thickness dimensions w1 and w5 of the first and second front board materials 2F are set to be shorter than the thickness dimensions w2 and w6 of the first and second rear board materials 2R.

[0072] This not only allows the second board 2 to be suitably changed between the unfolded position (T) and the folded position (M) with the folding portion H as the center of rotation, but also allows for flexible design so that the relative positions of the first and second boards 1 and 2 are stable when the second board 2 is in the unfolded position (T).

[0073] The present invention is not limited to the above-described embodiment.

[0074] The location of the clips on the first board is not limited to that shown in the above embodiment, and may be any location that does not interfere with the second board in the folded position.

[0075] For example, clips may be arranged along both the left and right ends of the first board.

[0076] The second board may be configured so as not to interfere with the clip in the folded position by forming a notch or a hole therein.

[0077] The clipboard body is not limited to being made only of synthetic resin components, but may be made entirely or partially of components other than synthetic resin.

[0078] The number of bending portions provided on the clipboard body is not limited to one as shown in the above-described embodiment, but may be multiple.

[0079] The clip may have a variety of specific configurations as long as it is capable of clamping documents. For example, the clip may have no raised portion, or the base member and clamping member may be made of the same material.

[0080] The number of clips is not limited to one, but a plurality of clips may be provided for the first board.

[0081] The second board may not be configured to be able to change its position between the folded position and the unfolded position while the clip remains in a state in which the document is held therein.

[0082] The inclination of the first end face of the first board and the second end face of the second board can be set appropriately so that the angle α when they are engaged is less than 180°. For example, either the first end face or the second end face may not be inclined, i.e., may be approximately perpendicular to the center line of the thickness direction of the first and second backing board materials.

[0083] Here, Figure 17 shows an example of another embodiment of the first backboard material 1R constituting the first board 1 and the second backboard material 2R constituting the second board 2. In the example of Figure 17, the first end face t1 is set to form a 90° angle with respect to the thickness-wise center line c1 of the first backboard material 1R, and the second end face t2 is inclined with respect to the thickness-wise center line c2 of the second backboard material 2R. In other words, only one end face, i.e., the second end face t2, is inclined. Even in this case, the desired purpose can be achieved.

[0084] Furthermore, the specific configuration of each part is not limited to the above embodiment, and various modifications are possible within the scope of the present invention. [Explanation of symbols]
