[0044] The following is for reference Figures 1-16 One embodiment of the present invention will be described. Furthermore, the vertical and horizontal directions in this embodiment are defined for ease of explanation.

[0045] In this embodiment, the invention is applied to a clamping board whose size can be changed by folding the portion that can serve as a platform for document P.

[0046] The clamp comprises: a clamp body A having a bent portion H located at the center in the vertical direction and extending in the horizontal direction; a single clip B disposed on the clamp body A and capable of holding a document P; and a storage pocket C disposed on the back side of the clamp body A.

[0047] like Figure 5 As shown in (a), the clamp body A is formed by setting the second plate 2 to an unfolded position (T), thereby creating a platform area where the first plate 1 and the second plate 2 together can serve as a pad suitable for an A3-sized document P. Furthermore, as... Figure 5 As shown in (b), the clamp body A is formed by setting the second plate 2 to a folded position (M), thereby forming a platform area that can become a pad suitable for an A4 size document P.

[0048] In other words, the clamp in this embodiment is configured to hold documents P of different sizes, such as A3 and A4, in a common clamp B provided on the first plate 1 and to use them flexibly.

[0049] Furthermore, by setting the second plate 2 to a folded position (M), the clamp can be made into a compact overall size suitable for carrying.

[0050] The following is a detailed description of the splint.

[0051] <<Clamping Body A>>

[0052] The clamp body A includes: a first plate 1 with a single clamp B disposed in the center of the upper part of the front side in the left-right direction, and a second plate 2 continuously disposed with the lower end of the first plate 1 via a bending part H.

[0053] <First Board 1>

[0054] The first plate 1 has a first surface plate 1F that is horizontally elongated and generally rectangular, and a first back plate 1R that is horizontally elongated and generally rectangular and is mounted on the back side of the first surface plate 1F.

[0055] The thickness w2 of the first back sheet 1R is set to be longer than the thickness w1 of the first surface sheet 1F. The first back sheet 1R has rigidity that almost does not allow for bending deformation in the thickness direction, while the first surface sheet 1F only allows for slight bending deformation in the thickness direction under relatively strong loads.

[0056] The vertical dimension w3 of the first surface panel 1F is set to be longer than the vertical dimension w4 of the first back panel 1R. The upper edge of the first surface panel 1F and the upper edge of the first back panel 1R are set to be approximately aligned. At the lower end of the first surface panel 1F, a first extension portion 11 is provided that cantilevered to a position below the lower edge e1 of the first back panel 1R.

[0057] The first surface plate 1F and the first back plate 1R are both components made of synthetic resin. The first surface plate 1F and the first back plate 1R are joined together by spot welding their peripheral portions to each other at multiple locations. That is, the rear surface of the first surface plate 1F, excluding the first extension 11, is joined to approximately the entire area of ​​the front surface of the first back plate 1F. Furthermore, in the accompanying drawings, the spot welded portions are indicated by reference numeral i.

[0058] A through hole 12 for inserting a shoulder strap is provided in the upper left and right corners of the first plate 1.

[0059] A recess 13 is formed at the center of the left and right outer edges of the first plate 1 in the vertical direction, which is capable of accommodating the left and right ends of the storage pocket C. The recess 13 is elongated in the vertical direction and is provided in pairs on the left and right sides of the first plate 1. The recess 13 is composed of a surface recess 13f provided at the left and right ends of the first surface plate 1F and a back recess 13r provided at the left and right ends of the first back plate 1R.

[0060] In this embodiment, the inward recessing degree of the surface recess 13f is set to be greater than the inward recessing degree of the back recess 13r. Compared with the back recess 13r in the first back panel 1R, the surface recess 13f is significantly recessed inward, i.e., towards the center of the first panel 1 in the left-right direction. By setting the recessing degrees of the surface recess 13f and the back recess 13r in this way, the welded portions 8 provided at the left and right ends of the storage pocket C can be welded to the front surface of the first back panel 1R exposed through the surface recess 13f after passing around the left and right outer edges of the first back panel 1R corresponding to the back recess 13r.

[0061] <Second Board 2>

[0062] The second plate 2 has a second surface plate 2F that is horizontally elongated and generally rectangular, and a second back plate 2R that is horizontally elongated and generally rectangular and is mounted on the back side of the second surface plate 2F.

[0063] The thickness w6 of the second back sheet 2R is set to be longer than the thickness w5 of the second surface sheet 2F. The second back sheet 2R has rigidity that almost does not allow for bending deformation in the thickness direction, while the second surface sheet 2F allows for slight bending deformation in the thickness direction under load.

[0064] Furthermore, the thickness w5 of the second surface panel 2F is set to be approximately the same as the thickness w1 of the first surface panel 1F. Similarly, the thickness w6 of the second back panel 2R is set to be approximately the same as the thickness w2 of the first back panel 1R.

[0065] The second surface panel 2F is integrally formed with the first surface panel 1F via a bend H extending linearly in the left-right direction. That is, the first and second surface panels 1F and 2F are integrally and continuously disposed via the bend H. Figure 9 As shown, the first and second surface plates 1F and 2F, and a single bent portion H between them are disposed on a sheet of synthetic resin.

[0066] The vertical dimension w7 of the second surface panel 2F is set to be shorter than the vertical dimension w8 of the second back panel 2R. The lower edge of the second surface panel 2F and the lower edge of the second back panel 2R are set to be approximately aligned. At the upper end of the second back panel 2R, a second extension portion 21 is provided, which cantilevered to a position above the upper edge of the second surface panel 2F.

[0067] The second surface plate 2F and the second back plate 2R are both made of synthetic resin. The second surface plate 2F and the second back plate 2R are joined together by spot welding their peripheral portions to each other at multiple locations. That is, approximately the entire rear surface of the second surface plate 2F is joined to the front surface of the second back plate 2R, except for the portion of the second extension 21. Furthermore, in the accompanying drawings, the spot welded portions are indicated by reference numeral i.

[0068] A through hole 22 for shoulder strap insertion is provided at the lower left and right corners of the second plate 2.

[0069] A fixing strap J extending in the left-right direction is provided on the second plate 2 to hold the document P on the surface of the second plate 2. Anti-detachment members k are provided at both ends of the fixing strap J. The anti-detachment members k are inserted from the front side to the back side into the mounting holes 23 provided at both ends of the second plate 2 and engage with the back side of the second plate 2.

[0070] The fixing strap J functions to restrain the document P (e.g., an A3-sized document) placed on the unfolded body A of the clamping plate in an unfolded position (T) so that it is not blown open by the wind, for example, outdoors. In addition, by engaging the fixing strap J with the first plate 1 in a manner that surrounds the rear and sides of the first plate 1, the folded position (M) of the second plate 2 can be stably maintained.

[0071] The second plate 2 can be in an unfolded (T) and a folded (M) position. In the unfolded (T) position, the second plate 2, together with the first plate 1, can form a continuous platform for the document P, that is, a pad for the document P of size A3 that is clamped in the clip B. In the folded (M) position, the second plate 2 is bent at the bending part H (with the bending part H as the rotation center) and folded toward the surface side of the first plate 1 to form a platform for the document P, that is, a pad for the document P of size A4 that is clamped in the clip B, without interfering with the clip B.

[0072] The second plate 2 is set to a size that does not interfere with the clamping member b2 of the clip B in the folded position (M). The upper edge e2 of the second plate 2 is set to be located below the clip B in the folded position (M).

[0073] That is, the upper edge e2 of the second plate 2 is set to separate from the clamping member b2 of the clip B in the folded position (M). In other words, the clamp is configured such that, when the clip B is clamping the document P, the second plate 2 can change its position between the folded position (M) and the unfolded position (T).

[0074] The second plate 2 is configured such that, in the unfolded position (T), the outer surface of the second surface plate 2F faces the front of the pad that becomes the document P. On the other hand, in the folded position (M), the outer surface of the second back plate 2R faces the front of the pad that becomes the document P, and the outer surface of the second surface plate 2F faces rearward and is opposite to the front surface of the first plate 1.

[0075] In this embodiment, when the second plate 2 is in an unfolded position (T), the lower end face (first end face t1) of the first back plate 1R and the upper end face (second end face t2) of the second back plate 2R can face each other and dock.

[0076] The first and second plates 1 and 2 are configured such that, in the unfolded posture (T), the first end face t1 and the second end face t2 are roughly in contact with each other as a whole.

[0077] In this embodiment, the first end face t1 of the first back panel 1R and the second end face t2 of the second back panel 2R are both inclined. The first end face t1 is inclined relative to the thickness direction centerline c1 of the first back panel 1R. The second end face t2 is inclined relative to the thickness direction centerline c2 of the second back panel 2R.

[0078] More specifically, when viewed with the thickness direction centerlines c1 and c2 as horizontal references, both the first end face t1 and the second end face t2 are inclined downwards, that is, towards the direction away from the first and second surface plates 1F and 2F, gradually moving outwards.

[0079] Furthermore, the angle α of the second board 2 relative to the first board 1 in the unfolded position (T) is limited to less than 180°. In addition, when the second board 2 in the unfolded position (T) is in a position that is excessively bent relative to the first board 1, it will impair writeability. Therefore, the angle α of the second board 2 relative to the first board 1 in the unfolded position (T) is preferably set in the range of 170° to less than 180°.

[0080] By setting the angle α in the unfolded posture (T) to less than 180°, the second plate 2 in the unfolded posture (T) is less likely to droop downward relative to the horizontal line of the first plate 1 (which is the line that is approximately consistent with the center line c1 of the thickness direction of the first back plate 1R) even if the member is flexed and deformed. Therefore, the writeability of the document P placed on the second plate 2 is excellent.

[0081] <Clip B>

[0082] Clip B holds document P. Clip B has a base member b1 formed of a metal plate and mounted on a first plate 1, and a clamping member b2 formed by bending a metal rod and supported so as to be rotatable relative to the base member b1.

[0083] The clamping member b2 is able to clamp the document P between itself and the base member b1. The clamping member b2 is subjected to force in the direction of the base member b1 by means of a spring G between itself and the base member b1, so that the top clamping part b21 extending in the left-right direction clamps the document P.

[0084] The base member b1 is roughly rectangular when viewed from the front. The base member b1 is mounted to the first plate 1 using rivets V as fasteners. In addition, the first plate 1 is provided with holes 14 for the rivets V to pass through.

[0085] In the base member b1, a raised portion b11 is formed adjacent to the top clamping portion b21 of the clamping member b2. The raised portion b11 is located at a position that is further downward than the top clamping portion b21 of the clamping member b2. The raised portion b11 is located at the lower end of the base member b1. The raised portion b11 can smoothly guide the document P held by the top clamping portion b21 and the base member b1 towards the front of the second plate 2, which is in a folded posture (M).

[0086] <Storage Pocket C>

[0087] The storage pocket C forms a storage space sp between itself and the first back panel 1R. This storage space sp can hold the document P and the clear holder and opens upwards. The storage pocket C is made of a sheet of synthetic resin.

[0088] The storage pocket C comprises: a pocket body 3, which is approximately rectangular in shape, with its left-right dimension w10 set to be approximately the same as the left-right dimension w9 of the longest portion in the first plate 1; a flap 4, which extends upward from the upper edge of the pocket body 3 via a fold line n1; a lower side panel 5, which extends outward from the lower edge of the pocket body 3 via a fold line n2; and a lower side welded portion 6. 6 extends outward from the outer edge of the lower side of the joining portion 5 via fold line n3 and is fused to the rear surface of the lower part of the first back panel 1R; left and right joining portions 7 extend outward from the left and right side edges of the pocket body 3 via fold line n4; and left and right fused portions 8 extend outward from the outer edge of the left and right joining portions 7 via fold line n5 and are fused to the front surface of the first back panel 1R exposed through the surface recess 13f in the first surface panel 1F.

[0089] The left-right dimension w10 of the pocket body 3 is approximately the same as the left-right dimension w9 of the longest part in the first plate 1. By setting the left-right dimension w10 of the pocket body 3 in this way, it is not only easy to obtain the longest possible internal dimension that can accommodate the transparent retainer in the storage space sp, but also easy to maintain the width dimension of the drawer that can be stored in a typical trolley.

[0090] A fold line 5c, which forms the lower edge of the storage pocket C, is provided in the center of the width direction of the lower side of the connecting part 5.

[0091] The width w11 of the left and right connecting parts 7 is set to be larger than the thickness w6 of the first back panel 1R. With this configuration, a storage space sp can be reasonably formed between the pocket body 3 and the first back panel 1R.

[0092] The left and right joining portions 7 and the left and right welded portions 8, which are the left and right ends of the storage pocket C, extend from the back side to the front side, bypassing the left and right end edges of the first plate 1 in the main body of the clamping plate A. Furthermore, the left and right welded portions 8 are fixedly joined to the surface side of the first plate 1 in the main body of the clamping plate A by welding. The left and right joining portions 7 are configured to extend in a front-back direction substantially orthogonal to the pocket body 3, and a portion of the left and right joining portions 7 is located within the recess 13 in the first plate 1.

[0093] For the installation procedure of storage pocket C, please refer to the following instructions. Figures 13-16 Please provide an explanation.

[0094] First, such as Figure 13 As shown, the first back panel 1R is prepared for mounting the storage pocket C. At this stage, the first back panel 1R is spot-welded to the first surface panel 1F.

[0095] Next, as Figure 14 As shown, the lower side of the welded portion 6 in the storage pocket C is welded to the lower end outer surface of the first back panel 1R. The lower side welded portion 6 is welded to the first back panel 1R after being aligned such that the fold line 5c of the lower side joining portion 5 is approximately aligned with the lower edge e1 of the first back panel 1R.

[0096] Next, as Figure 15 As shown, the pocket body 3 is moved toward the outer surface of the first back panel 1R with the fold line 5c as the rotation center.

[0097] Then, as Figure 16 As shown, after the left and right joining portions 7 and the left and right welded portions 8 are wrapped around the back recesses 13r that serve as the outer edges of the first back plate 1R, the left and right welded portions 8 are welded to the front surface of the first back plate 1R. The surface recesses 13f provided on the first surface plate 1F do not interfere with the left and right welded portions 8. Therefore, the left and right welded portions 8 are less likely to form protrusions or raised portions on the front surface side of the first plate 1 that would obstruct writing or damage the folding posture (M) of the second plate 2.

[0098] As described above, the clamp in this embodiment includes: a clamp body A having a bending portion H; and a clip B disposed on the clamp body A and capable of clamping a document P. Furthermore, the clamp body A includes a first plate 1 on its surface side with the clip B disposed thereon, and a second plate 2 continuously disposed on the first plate 1 via the bending portion H. The second plate 2 can be in an unfolded posture (T) that, together with the first plate 1, forms a continuous platform for the document P, and a folded posture (M) that, folded about the bending portion H as a rotation center towards the surface side of the first plate 1, forms a platform for the document P without interfering with the clip B.

[0099] Therefore, it can provide clips for different sizes of documents P, such as A3 and A4, which can be held in clips B and used flexibly.

[0100] The clamp B has a base member b1 mounted on the first plate 1 and a clamping member b2 disposed on the base member b1. A raised portion b11 is provided on the base member b1 at a position adjacent to the clamping member b2.

[0101] Therefore, the document P held in the clip B can be properly guided to the outer surface of the second plate 2 in a folded position (M) by using the raised part b11.

[0102] The end edge of the second plate 2 is set to be separated from the clamping member b2 in the folded posture (M). When the clip B is clamping the document P, the second plate 2 is configured to be able to change posture between the folded posture (M) and the unfolded posture (T).

[0103] Therefore, the document P held in clip B is less likely to interfere with the upper edge of the second plate 2 in the folded position (M), so the second plate 2 can be flexibly changed between the folded position (M) and the unfolded position (T) while the document P is held in clip B.

[0104] The first plate 1 has a first surface plate 1F that is generally rectangular in shape and a first back plate 1R that is generally rectangular in shape and mounted on the back side of the first surface plate 1F. The second plate 2 has a second surface plate 2F that is generally rectangular in shape and a second back plate 2R that is generally rectangular in shape and mounted on the back side of the second surface plate 2F. Furthermore, the first surface plate 1F and the second surface plate 2F are integrally and continuously provided via a bending portion H.

[0105] Therefore, when the second plate 2 is in an unfolded position (T), it is possible to adopt a configuration that is approximately coplanar with the front surface of the first plate 1.

[0106] The thickness dimensions w1 and w5 of the first and second surface panels 1F and 2F are set to be shorter than the thickness dimensions w2 and w6 of the first and second back panels 1R and 2R.

[0107] Therefore, not only can the second plate 2 be appropriately changed between the unfolded posture (T) and the folded posture (M) with the bending part H as the rotation center, but also when the second plate 2 is in the unfolded posture (T), the postures of the first and second plates 1 and 2 can be flexibly made stable.

[0108] Furthermore, the present invention is not limited to the embodiments detailed above.

[0109] The location where the clip is positioned relative to the first plate is not limited to the location shown in the above embodiment. The location where the clip is positioned relative to the first plate is any position where the second plate, in its folded position, will not interfere with it.

[0110] For example, clips can also be installed along the left and right ends of the first plate.

[0111] The second plate can also be configured such that it has a through-hole or notch, so that it does not interfere with the clip when folded.

[0112] The main body of the plywood is not limited to being made of synthetic resin components alone; it may also be composed of all or part of components other than synthetic resin components.

[0113] The bending portion provided on the main body of the clamping plate is not limited to a single bending portion as shown in the above embodiment, but may also be multiple bending portions.

[0114] A clip only needs to be able to hold documents, and its specific structure can be varied. For example, a clip can be a clip without raised parts, or a clip where the base component and the clamping component are made of the same component.

[0115] The clips are not limited to a single clip; there can be multiple clips relative to the first plate.

[0116] Alternatively, when the clip holds the document, the second plate is not configured to change its orientation between a folded and unfolded position.

[0117] The inclination of the first end face of the first plate and the second end face of the second plate can be appropriately set such that the angle α is less than 180° when they are engaged. For example, either the first end face or the second end face may not be inclination, that is, they may be approximately orthogonal to the center lines of the thickness direction of the first and second back plates.

[0118] Here, Figure 17 A figure showing an example of another embodiment of the first back sheet 1R constituting the first plate 1 and the second back sheet 2R constituting the second plate 2. Figure 17 In the example, the first end face t1 is set at 90° relative to the thickness direction centerline c1 of the first back panel 1R, and the second end face t2 is inclined relative to the thickness direction centerline c2 of the second back panel 2R. That is, only one side, namely the second end face t2, is inclined. Even with this configuration, the desired purpose can be achieved.

[0119] Furthermore, the specific configuration of each part is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
