Description

  The present invention relates to a paper folding apparatus suitable for making a regular form sheet three-folded in order to put a regular form sheet such as e.g. mail or a guide letter into an envelope.

In order to insert fixed forms such as e-mails and guide letters into an envelope, the sheet is generally folded in three so that the long side of the sheet has a width of 1/3. If the paper is folded in three, the short side of the paper is not aligned in the folded state, and everyone is experiencing the problem that the finished appearance is not good.
On the other hand, there is a machine that, for example, A4-size paper is folded into several thousands at a time for a company that sends out a large amount of direct mails such as business documents and advertisements. However, this is expensive and its handling also requires some degree of mastery. Therefore, such a tri-fold machine can not be handled at home.

Therefore, in general homes, for example, proposals have been made for a paper folding apparatus in which A4 size paper can be folded in three.
For example, Patent Document 1 discloses a base plate on which fixed form paper is placed, and a configuration in which a narrow rectangular plate material is attached to a central portion of the base plate to be able to open and close with respect to the base plate.
According to the paper folding apparatus disclosed in the patent document 1, there is a problem that the position of the sheet placed on the base plate is not determined, and the three-folded part fluctuates each time according to the position of the sheet on the base plate. It is left.

  Further, in Patent Document 2, there is provided a base plate on which a fixed form sheet is placed, and a rubber magnet plate member having one end attached to the base plate and sandwiching the fixed form sheet with the base plate. The structure which provided the magnet sheet which adsorb | sucks a plate member on a base board on a base board is disclosed. According to the paper folding device disclosed in Patent Document 2, since the guide portion is formed at the left end of the base plate, the sheet placed on the base plate can be positioned. Therefore, according to the paper folding device disclosed in Patent Document 2, the problems in the paper folding device disclosed in Patent Document 1 are improved.

However, according to the paper folding apparatus disclosed in Patent Document 2, as shown in FIG. 4 of Patent Document 2, the plate member made of a rubber magnet has a crease in the sheet because the material is soft and the stiffness is weak. There is a problem that it is difficult to give. In addition, there is also a problem that misalignment is likely to occur in the fold due to the material having a soft edge of the plate member.
Furthermore, since the rubber magnet plate member is attracted to the magnet sheet on the base plate, the practical problem that it is difficult to pull out due to frictional resistance when pulling out the sheet folded in three from the plate member is also left Be

On the other hand, in the paper folding apparatus disclosed in Patent Document 3, a base plate on which a fixed sheet is placed and a rectangular plate member (plate member) having a narrow width on the base plate are a pair of U-shaped stoppers A gold mounted openable / closable configuration is employed.
The pair of U-shaped clasps are attached to a holding frame formed along one side of the base plate, and on three sides of the base plate, an edge plate is erected in a direction orthogonal to the base plate It is configured to be able to stack and store a large amount of paper on the base plate.

  The paper folding apparatus disclosed in Patent Document 3 is suitable for stacking a relatively large amount of sheets on a base plate and sequentially folding the sheets in three, for example, to be routinely used in general homes In order to easily fold a few sheets of paper at one time, the overall configuration is large. That is, according to the paper folding apparatus disclosed in Patent Document 3, there is a problem that the overall size (especially thickness) of the paper folding apparatus is large, and the manufacturing cost including the number of assembling steps of each member inevitably increases. is there.

  The present invention has been made to solve the problems of the conventional paper folding apparatus disclosed in each of the above-mentioned patent documents, and for example, simplification and cost reduction to the extent that it can be handled in a 100 yen shop or the like. It is an object of the present invention to provide a paper folding apparatus for folding a fixed form sheet into three folds, which can realize the above. In addition, it is an object of the present invention to provide a paper folding apparatus which can be easily used in general homes and which can always expect the same finished appearance.

  The basic form of the paper folding apparatus according to the present invention, which was made to achieve the above-mentioned problems, is formed by projecting along a rim a linear guide body which one short side of a form sheet folded into three contacts. A rectangular base plate on which the fixed form sheet can be positioned and mounted by the guide body, and one edge is positioned at a position where the width of the form sheet is separated from the guide body The base plate is provided with a rectangular core plate to which one end in the longitudinal direction is attached with respect to the base plate, and the core plate is formed of a resin thin plate having elastic resilience capable of bending and deforming. The one end in the longitudinal direction is attached to the base plate via a linear gap forming member having a predetermined thickness, which is disposed orthogonal to the guide body and along the edge of the base plate. The other end of the core plate in the longitudinal direction is bent by the bending. The width between the one edge of the core plate and the other edge parallel to the edge is 1/3 of the width of the long side of the fixed form sheet. It is characterized in that it is configured to have a size exceeding.

  Further, in another form of the paper folding apparatus according to the present invention, a linear second guide body disposed parallel to the guide body and in contact with the other short side of the fixed form paper is: The distance between the guide body and the second guide body is set to be larger than the width of the long side of the fixed form sheet, and the second guide body is formed to protrude along the edge of the base plate. The other end of the core plate is positioned at a position apart from the folding width of the fixed form sheet.

Further, in another preferable embodiment, the base plate on the side of the base plate on which the other end in the longitudinal direction of the core plate is overlapped is shorter than the other end of the core plate in the longitudinal direction. A notch is formed in part of the edge of the.
Furthermore, it is desirable that a protrusion protruding toward the fixed form sheet, which is located between the core plate and the base plate, be disposed on the core plate.

  According to the above-described paper folding apparatus, the fixed form sheet is positioned relative to the base plate by bringing the short side of the fixed form sheet into contact with the linear guide body formed at the edge of the base plate. In this state, the fixed form sheet can be easily folded in three with the core plate at the center by folding the fixed form sheet by utilizing both end edges of the core plate formed of the resin thin plate. Subsequently, by pulling out the three-folded sheet from the core plate, it becomes possible to obtain a regular-shaped sheet in a neatly folded three-folded state.

In this case, since the core plate has a structure in which one end is attached to the base plate via a gap forming member having a predetermined thickness, a part of the sheet is between the base plate and the core plate. It is possible to provide a paper folding apparatus which can prevent occurrence of problems such as an obstacle to pulling out a fixed form sheet in a folded state in a tri-folded state, thereby ensuring a smooth operation.
Further, by forming the base plate and the core plate with resin thin plates, respectively, the whole can be provided extremely thinly and inexpensively, and the same finish with a neat appearance can always be expected and can be used easily. Paper folding apparatus can be realized.

FIG. 1 and FIG. 2 show a first embodiment of the paper folding device in perspective and top views, and FIG. 1 shows the paper folding device 1 with a fixed sheet (A4 paper) P1 attached. Further, in FIG. 2, the sheet P <b> 1 is indicated by an imaginary line (two-dot chain line).
The paper folding apparatus 1 can be placed on a base plate in a state in which approximately 3 to 5 sheets of paper are stacked, and the paper is folded in three from top to bottom in order, or these are stacked. It is assumed to be folded in three at a time in the state.

Reference numeral 2 denotes a rectangular base plate, and preferably, the base plate 2 is made of a resin plate having elastic recovery capable of bending and deforming, for example, a thin plate made of one vinyl chloride resin.
The base plate 2 has such a size that the whole of the fixed form paper P1 can be placed on the upper surface as shown in FIG. 1, and in this embodiment, the long side of the base plate 2 is generally The width of the long side of the A4 sheet P1 is added to the width of the guide body 3 described later. The short side of the base plate 2 is set to a size slightly larger than the width W2 of the short side of the A4 sheet P1 plus the width dimension of the gap forming member 4 described later.

  At the left side edge of the base plate 2 in the state where the long side of the base plate 2 is horizontal, the linear guide body 3 made of a resin material having a constant width and thickness along the left side edge is the base plate 2. It is placed and mounted on the top of the. When the sheet P1 is placed on the upper surface of the base plate 2 as shown in FIG. 1, the guide body 3 positions the sheet P1 on the base plate 2 by aligning the short side of the sheet P1. It is.

In FIG. 1, the short side of the sheet P <b> 1 is placed on the guide body 3 at a slight interval. A similar state is also shown in the cross-sectional view of FIG. 3. However, when the sheet P1 is folded in three, the left short side of the sheet P1 is disposed in contact with the guide body 3.
The guide body 3 is attached to the base plate 2 using an adhesive, but the resin constituting the base plate 2 and the guide body 3 is a material that can be thermally melted like the above-mentioned vinyl chloride resin and the like. In some cases, welding and joining using a high frequency welder can be suitably used.

Further, a linear gap forming member 4 made of a resin material having a constant width and thickness along the upper edge of the base plate 2 is attached to be orthogonal to the guide body 3. Further, one end portion in the longitudinal direction of the core plate 5 formed in a rectangular shape is attached to the upper surface of the central portion of the gap forming member 4.
Similar to the base plate 2, the core plate 5 is made of a resin plate having elastic resilience capable of bending and deforming, for example, a thin plate made of one vinyl chloride resin.

As a result, the other end of the core plate 5, one end of which is attached to the gap forming member 4, that is, the free end 5a side of the core plate 5, is appropriately bent and can be opened and closed with respect to the base plate 2. The sheet P1 can be easily mounted between the base plate 2 and the core plate 5.
Moreover, since the core plate 5 is attached to the base plate 2 via the gap forming member 4 having a predetermined thickness, as shown in FIG. An appropriate gap is formed between the plate 5 and the plate 5. Therefore, as described later, the sheet P1 which has been folded in three can be pulled out smoothly from the core plate 5.

An adhesive may be used to attach the gap forming member 4 and the core plate 5 to the base plate 2, but the resin constituting the base plate 2, the gap forming member 4 and the core plate 5 may be the vinyl chloride resin described above In the case of a material capable of heat melting as in the above, welding and joining using a high frequency welder can be used.
And, since the gap forming member 4 is disposed in a state of being orthogonal to the above-mentioned guide body 3, the long side of the sheet P 1 is in contact with it and the function as positioning of the long side of the sheet P 1 to the base plate 2 Can also play.

In addition, on the opposite side of the mounting position of the gap forming member 4 in the base plate 2, as shown in FIG. 2, three arc-shaped cutouts 2 a, along the straight edge of the base plate, 2b and 2c are formed.
The left and right notches 2a and 2c in FIG. 2 can be used when raising the left and right portions of the short side of the sheet P1 placed on the base plate 2 with a fingertip or the like when the sheet P1 is folded in three. it can. The central notch 2b is formed at a position where the longitudinal end (free end) 5a of the core plate 5 overlaps. Since the base plate 2 side is relatively shorter than the end (free end) 5a in the longitudinal direction of the core plate 5 due to the presence of the cutout portion 2b, the free end 5a of the core plate 5 is raised from the base plate 2 It becomes easy to pull out the sheet P1 folded in three from the core plate 5 with a fingertip.

  Further, at an end portion of the gap forming member 4, a through hole 6 which penetrates the gap forming member 4 and the base plate 2 is formed. The through-hole 6 can be used for hanging the folding device 1 at a hook portion or the like for storage, etc. through a string or the like as required.

According to the paper folding device 1 shown in FIGS. 1 to 4, as described above, the free end 5 a of the core plate 5 can be pulled up to mount the sheet P 1 on the base plate 2. At this time, the sheet P <b> 1 is positioned on the base plate 2 by using the guide body 3 and the gap forming member 4.
In this paper folding apparatus 1, as shown in FIG. 2, a dimension W3 between the guide body 3 and one end edge (left end edge) 5b of the core plate 5 is set to about 100 mm as an example. The width dimension W4 between the one end 5b of the core plate 5 and the other parallel end (right end) 5c is also set to about 100 mm.
That is, the width dimension W4 of the core plate 5 is made to exceed 1/3 of the width W1 of the long side of the A4 sheet P1.

The width of the long side W1 of the A4 sheet is 297 mm. Therefore, by folding the sheet P1 along the right side edge 5c of the core plate 5 shown in FIGS. 1 and 2, the width dimension W4 of the core plate 5 is Within the range, the right side of the sheet P1 can be folded in a state of being superimposed on the upper surface of the core plate 5. Subsequently, by folding the sheet P1 along the left side edge 5b of the core plate 5, the left side of the sheet can be folded in a state of being superimposed on the sheet P1 that has been previously folded.
In this state, by lifting the free end 5a of the core plate 5 and pulling out the three-folded sheet P1 from the core plate 5, it is possible to obtain a three-folded sheet in which the long side is approximately 100 mm. .

In the three-fold operation of the sheet P1 using the core plate 5, since the resin thin plate having elastic resilience capable of bending and deforming is used as the core plate 5, the left and right ends of the core plate 5 having appropriate hardness At the edges 5b and 5c, the folding position of the sheet P1 can be accurately determined and folded.
Therefore, it is possible to provide a paper folding apparatus that can always expect a similar finish with a well-designed appearance.

In the folding device 1 of the second embodiment, approximately 1/3 of the base plate 2 positioned on the right side of the core plate 5 is deleted.
Along with this, a hole 6 penetrating the core plate 5, the gap forming member 4 and the base plate 2 is formed at the corner of the core plate 5.
According to the paper folding device 1 of the second embodiment shown in FIG. 5, the same function and effect as the paper folding device 1 of the first embodiment described above can be obtained, and the planar dimensions of the base plate 2 are substantially reduced. Can contribute to the miniaturization of the paper folding apparatus.

6 to 8 show a third embodiment of the paper folding apparatus according to the present invention.
In the third embodiment, parts that perform the same functions as the parts described above, for example, shown in FIGS. 1 and 2 are indicated by the same reference numerals. Therefore, the detailed description is suitably omitted.
In the third embodiment, a second guide body linear along the right edge of the base plate 2 so as to be parallel to the left guide body 3 shown in FIGS. 1 and 2 described above. Is formed projecting. Therefore, in this embodiment, for convenience of explanation, the guide body on the left side in the figure is indicated by reference numeral 3A as a first guide body, and the guide body on the right side in the figure is indicated by reference numeral 3B as a second guide body.

The interval between the first guide body 3A and the second guide body 3B is set to be slightly larger than the width W1 of the long side of the A4 size standard sheet P1.
As shown in FIG. 7, the dimension between the first guide body 3A and one end edge (left end edge) 5b of the core plate 5 is W5, and the one end edge 5b of the core plate 5 and the other end are W5. The width dimension between the parallel edge (right side edge) 5c of W is W6, and the dimension between the right side edge 5c of the core plate 5 and the second guide body 3B is W7. Each of these dimensions is set to be approximately equal (W5 = W6 = W7).
Therefore, also in this embodiment, the width dimension W6 of the core plate 5 is made to be larger than 1/3 of the width W1 of the long side of the A4 sheet P1.

  Further, in this embodiment, a protrusion 7 protruding toward the sheet P <b> 1 located between the core plate 5 and the base plate 2 is disposed substantially at the center of the core plate 5. As shown in the enlarged cross-sectional view of FIG. 8, the protrusion 7 is formed with a spherical surface having a large curvature toward the sheet P1 placed on the base plate 2. In this example, it is made of resin The protrusion 7 made of resin is attached to the core plate 5 by bonding or fusion bonding. The protrusions 7 may be formed integrally with the core plate 5.

  Since the above-mentioned spherical surface having a large curvature abuts on the sheet P1 positioned on the base plate 2 by the first or second guide body 3A, 3B, etc., the protrusion 7 slips. Thus, the sheet P1 can be effectively held on the base plate 2 without any problem.

  Moreover, in this embodiment, for example, the through hole 6 through which a string or the like can be passed is formed at a corner portion of a part of the base plate 2. According to this, for example, the base plate 2 formed of one resin thin plate can be easily subjected to the hole drilling process, which can contribute to the cost reduction of the product.

The sheet folding apparatus 1 according to the third embodiment shown in FIGS. 6 to 8 is, for example, considered to facilitate three-fold operation of sheets for both right-handed and left-handed users.
That is, for a right-handed user, generally the sheet P1 is positioned on the base plate 2 by bringing the short side on the left side of the sheet P1 into contact with the first guide body 3A on the left side. By folding the sheet P1 along the edge 5c, the sheet is more likely to be folded in three.
According to the three-folding operation of sheets according to this order, the sheet P1 on the side of the right side edge 5c of the core plate 5 is first folded inward, and the sheet P1 is later folded along the left side edge 5b of the core plate 5 Folded to the top. According to this, the folding width of the right side of the sheet to be folded inward first becomes slightly smaller, and the folding width of the sheet to be folded on the back surface and the top surface is finished to be substantially equal.

On the other hand, left-handed users generally position the sheet P1 on the base plate 1 by aligning the short side of the right side of the sheet P1 with the second guide body 3B on the right side, and then the left end of the core plate 5 By folding the sheet P1 along the edge 5b, the sheet is more likely to be folded in three.
According to the three-folding operation according to this order, the sheet P1 on the side of the left side edge 5b of the core plate 5 is first folded inward, and the sheet P1 is later folded along the right side edge 5c of the core plate 5 It is broken. According to this, similarly to the above-described example, the left-side fold width of the sheet to be folded inward first becomes slightly smaller, and the fold widths of the sheet folded on the back and top sides become substantially equal. Finished.

  As described above, according to the paper folding apparatus according to the present invention, by forming the base plate and the core plate with, for example, a resin thin plate, it is possible to provide the whole extremely thin and inexpensive, and it can be used easily. It is possible to provide the paper folding apparatus which can always expect the same finish with a well-designed appearance and the like, and it is possible to obtain the operation effects as described in the column of the above-mentioned effects of the invention.
