Utility Model Registration No. 3048763

However, when the assembly method of Patent Document 1 is adopted, if the shape of the adhesive portion does not match the shape of the paste margin without error, part of the adhesive portion will be exposed after assembly, or part of the paste margin will be exposed. There is a risk that the tape may not be adhered, and clean assembly cannot be achieved. Moreover, since the paste margin and the adhesive portion are limited and small parts of the whole, there is a good chance that errors will occur during the manufacturing process.

SUMMARY OF THE INVENTION The present invention has been proposed in consideration of such circumstances, and its object is to provide a work sheet that allows neat assembly of a three-dimensional body using sheet materials.

In order to achieve the above object, the work sheet of the present invention is a work sheet for assembling a three-dimensional body by curving and folding a sheet material, the sheet material having an adhesive surface on the back surface, The adhesive surface includes a bonding adhesive portion for bonding the adhesive surfaces together.

Since the work sheet of the present invention has the structure described above, it is possible to neatly assemble a three-dimensional body using the sheet material.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. First, the basic configuration of the work sheet 1 according to the embodiment will be described.

The work sheet 1 is a sheet-like material for bending and folding a sheet material 10 to assemble a three-dimensional body 5 . The sheet material 10 has an adhesive surface 12 on the back surface, and the adhesive surface 12 includes a bonding adhesive portion 12a for bonding the adhesive surfaces 12 together.

As the adhesive for the adhesive surface 12, for example, an acrylic adhesive having excellent transparency, heat resistance, and weather resistance can be suitably used. Regarding the adhesive strength of the acrylic pressure-sensitive adhesive, it is possible to design various types from low-adhesion types to strong-adhesion types, which is highly convenient.

In addition, it is desirable to use a material that has weak adhesive strength at the time of initial adhesion and that becomes stronger as time passes. When using this work sheet 1, it is desirable to use an adhesive that can be redone when a mistake is made in pasting or pasting. Some are easily peeled off in stages, and it is desirable to use such.

Specific examples of this type of work sheet 1 include those shown in FIGS. 1 and 2, those shown in FIGS. 3 and 4, and those shown in FIGS.

All of these examples are configured such that the adhesive surface 12 is formed on the entire back surface of the sheet material 10 and further provided with a release paper 7 for protecting the adhesive surface 12 in a state before use (assembly). The release paper 7 also serves as a mount for the sheet material 10 in a predetermined developed shape for forming a three-dimensional body, and has a rectangular shape or the like larger than the sheet material 10 (hereinafter referred to as the sheet material main body 10). It is said that A peripheral portion of the sheet material body 10 is a blank portion 13 that is not used as the sheet material body 10 .

The sheet material main body 10 may be formed of a synthetic resin sheet such as a vinyl chloride sheet, a paper sheet, or the like, and a solvent inkjet printing sheet is suitable, for example. Assuming that the three-dimensional body 5 is used outdoors, it is desirable to use a synthetic resin sheet with low hygroscopicity, a sheet with a laminated surface, or the like as the sheet material main body 10 . The printing method for the sheet material main body 10 is not particularly limited, but a roll-type inkjet printer capable of large-size printing and using brightly colored eco-solvent ink is preferably used.

In addition, before use, the sheet material body 10 and the blank portion 13 are in a detachable adhered state on the backing paper (release paper 7). The sheet material body 10 is notched at its contour so that it can be removed for use.
They will be described in order below.

FIG. 1 is a plan view of a work sheet 1 for assembling a substantially triangular pyramid-shaped accessory case (see FIG. 2), which is open on one side and hollow inside. The sheet material body 10 used for assembling the three-dimensional body 5 has seven equilateral triangular portions in a row, two of which are connected to one side of each equilateral triangular portion with an extending piece 17. ing. One of the two equilateral triangular portions connecting the extending pieces 17 is slightly smaller than the other equilateral triangular portion.

In the blank space 13 that is not used for assembly, there are notes on the assembly method, and in the illustration, folding techniques are indicated by different types of lines (folding lines 18), specifically broken lines/folding ( It is printed that it is a valley fold, a two-dot chain line/valley fold, and a one-dot chain line/mountain fold. This note is used when folding the back side up, and as shown in FIG. It is

Moreover, it is desirable that such folding lines 18 are not printed on the surface 11 of the sheet material main body 10 for aesthetic reasons, but they may be printed in consideration of ease of folding. In FIG. 1, for the sake of convenience, a thin line is shown in the portion corresponding to the folding line 18 on the back surface.

Here, the fold-over fold is a method of folding the adhesive surfaces 12 (bonding adhesive portions 12a) so as to bond them together, and the valley-fold is a valley fold other than the fold-over fold. The mountain fold is a folding method in which the front surface 11 of the sheet material body 10 is folded so as to bring it closer.

In addition, not only the notes described above, but also sentences, pictures, and diagrams representing the assembly procedure described below may be printed on the margin portion 13 .

The three-dimensional body 5 can be assembled according to the procedure shown in FIG. The entire back surface of the sheet material main body 10 serves as an adhesive surface 12, of which the hatched portion in the drawing is the portion to be adhered to the front surface 11 of the sheet material main body 10, and the shaded portion is the adhesive surface 12 after the three-dimensional body 5 is assembled. This is the exposed part. The exposed adhesive surface 12 is attached to another object after assembly. The blank parts on the back surface other than these are used as the adhesive part 12a for bonding where the back surfaces (bonding surfaces) are bonded together.

First, in unfolded state A, by folding along the folding lines 18 in the direction of the arrows in the figure, all the six large equilateral triangular portions 15 are adhered together by the adjacent large equilateral triangular portions 15 and the adhesive surfaces 12, As a result, the adhesive portions 12a for bonding are hidden, and as a result, the shape of the intermediate state B is formed.

Then, three equilateral triangles (marked with a circle in the figure) formed by pasting together form a triangular pyramid, and the extending piece 17 connected to the small equilateral triangular portion 16 is mountain-folded toward the surface 11 halfway. The shape of state C is formed.

Next, the small equilateral triangular portion 16 is folded so as to overlap the surface 11 of the large equilateral triangular portion 15 connected thereto (mountain fold when viewed from the back side), and the surface 11 of the large equilateral triangular portion 15 is folded. The intermediate state D is formed by sticking the adhesive surface 12 of the extension piece 17 to a part of the . At this time, the adhesive surface 12 on the back surface of the small equilateral triangular portion 16 is exposed.

Finally, the bonding adhesive portion 12a of the extension piece 17 of the large equilateral triangular portion 15 is attached to the end of one side of the adhesive surface 12 of the exposed small equilateral triangular portion 16, thereby finally In state E, a substantially triangular pyramid-shaped accessory case is formed with the apex facing downward and the opening facing upward.

In this final state E, a portion (hatched portion) of the adhesive surface 12 of the small equilateral triangular portion 16 is exposed, and this portion can be attached to, for example, a pillar, a desk, etc., indoors so as to be used as an accessory case. is fixed.

In this way, when the assembled accessory case is in a fixed state, any adhesive surface 12 is attached to the bonding adhesive portion 12a, the surface 11 of the sheet material main body 10, or another object, so that it is exposed. Hidden without doing.

In this way, the three-dimensional body 5 is assembled in a clean state without exposing the adhesive surface 12. - 特許庁Moreover, although the inside of the triangular pyramid of the accessory case is exposed, since the surface 11 of the sheet material main body 10 is exposed by bonding the bonding adhesive portions 12a to each other, there is no fear that the appearance will be spoiled. If various colored patterns are applied to the surface 11 of the sheet material body 10, they will appear on the outer surface and the inner surface of the accessory case, thereby improving the design.

In addition, since the adhesive surface 12 is formed on the entire back surface of the sheet material main body 10 as in the present embodiment, folding errors can be reduced compared to the case where the adhesive surface 12 is locally formed, and as a result, the sheets can be laminated together. Also, the three-dimensional body 5 can be assembled in a clean state. In addition, if fold lines 18 such as fold lines, mountain fold lines, and valley fold lines are printed on the adhesive surface 12 as in the present embodiment, folding errors are less likely to occur and the paper can be neatly folded.

In addition, there is no need for scissors or glue, so there is no hassle when assembling. In the examples of FIGS. 1 and 2, the sheet material body 10 is not separated and is composed of a single sheet, so there is no risk of partial loss of the material, and there is almost no possibility of erroneous pasting. do not have.

Next, the examples shown in FIGS. 3 and 4 will be described. FIG. 3 is a plan view of the work sheet 1 for assembling the hollow openable dice shown in FIG.

The sheet material main body 10 used for assembling this three-dimensional body 5 is not formed integrally as in the example of FIG. Also in this working sheet 1, the entire back surface of the sheet material main body 10 is used as the adhesive surface 12, and the release paper 7 is attached to the adhesive surface 12 and the back surface of the blank portion 13. As shown in FIG.

One of the two types of separating members 20 and 26 is a main body sheet 20 (see FIG. 3(a)) in an unfolded state, which is formed by connecting six square portions 21 to form a dice main body. The other of the separating members 20 and 26 is a cover sheet 26 (see FIG. 3(b)) for bonding to the back surface of the main body sheet 20. As shown in FIG. The cover sheet 26 is divided into squares corresponding to the six square portions of the body sheet 20 .

The cover sheet 26 may also be formed as an integral sheet like the main body sheet 20, but it is desirable that the sheets are separated in order to facilitate lamination. In order to facilitate folding, each of the cover sheets 26 should be made slightly smaller than the square portion 21 of the main body sheet 20 to such an extent that the linear adhesive at the valley fold portion is not exposed when folded. is desirable.

The body sheet has four margin portions 22, and one square portion 21 is connected to an extension piece 24. - 特許庁The adhesive surface 12 on the back surface of the square portion 21 is adhered to the front surface of the four paste margin portions 22 as indicated by the arrows in FIG. 3(a). On the back side of the square portion attached to the surface of the paste margin portion, an adhesive surface 12 is formed integrally by the adhesive portion for bonding of the square portion and the adhesive portion for bonding of the paste margin portion. A cover sheet 26 is attached to the adhesive surface 12 .

Further, the square portion on which the extension piece 24 is formed is used as the open/close lid 23 of the dice, and the extension piece 24 is used as an insertion piece when the open/close lid 23 is closed. A cover sheet 26 having the same shape is attached to the adhesive surface 12 (bonding adhesive portion 12a) on the back surface of the square portion 21 with the extending piece 24 attached.

A dice made by assembling these separating members 20 and 26 can be used as an accessory case. As shown in FIG. 4B, when the opening/closing lid 23 is opened, the inner surface and the surface of the cover sheet 26 attached to the back of the opening/closing lid 23 are exposed.

Therefore, if the surface of the cover sheet 26 is colored and patterned, there is no fear that the appearance will be spoiled even when the opening/closing lid 23 is opened and the interior is exposed, and the design of the interior of the triangular pyramid can be expressed.

Next, the examples shown in FIGS. 5 and 6 will be described. FIG. 5 is a plan view of the work sheet 1 for assembling the cubic character shown in FIG.

As shown in FIGS. 5(a) to 5(d), the sheet material main body 10 used for assembling this three-dimensional body is composed of four kinds of separation materials 30, 33, 35, and 36. FIG.

The separation material 30 shown in FIG. 5A is a body sheet 30 having six square portions 31 continuously, and the separation material 33 shown in FIG. A cover sheet 33 is provided for matching. A character's face is printed on one surface of the square portion 31 .

The body sheet 30 has seven margin portions 32 . As for the four adhesive margin portions 32 among these, as indicated by arrows in FIG. Then, the cover sheet 33 is bonded to the adhesive surface 12 which is integrated with the bonding adhesive portion 12 a of the square portion 31 and the bonding adhesive portion 12 a of the paste margin portion 32 .

In addition, the three margin portions 32 formed in one square portion 31 at the end portion of FIG. I wish I could wear it.

5(c) and 5(d) are sheets for forming the pair of arm portions 37 and the pair of antenna portions 38 shown in FIG. 35 and 36 are axisymmetrically shaped, and the adhesive surface 12 on the back side is an adhesive portion 12a for bonding except semicircular portions 35a and 36a at both ends.

The separating members 35 and 36 shown in FIGS. 5(c) and 5(d) are formed by folding the semicircular portions 35a and 36a outward and adhering the rest to form the arm portion 37 and the antenna portion 38 as shown in FIG. It is formed. Then, the two semi-circular portions 35a and 36a are respectively folded outward, whereby the two semi-circular portions 35a and 36a are connected to form the substantially circular adhesive surface 12. As shown in FIG. The character body is assembled by sticking the adhesive surface 12 to predetermined parts of the dice body as an arm part 37 and an antenna part 38 .

This character body can be used as a figurine or toy for infants and the like. As described above, all the adhesive surfaces of the separation material are hidden by the cover sheet 33 or attached to other surfaces, so that they are not exposed and are finished in a clean state.

When the character body is used as an ornament or playground equipment, a cubic wooden material that matches the internal shape may be accommodated in the internal cavity during assembly. By enclosing such a material, it is also possible to facilitate pasting of the paste margin portion 32 . Also, a permanent magnet may be placed in the cavity. For example, instead of attaching the cover sheet 33 to the back side of the cavity, a permanent magnet may be attached, so that the character body can be attached to a steel rack or the like.

According to the work sheet 1 as described above, various three-dimensional bodies 5 such as origami, accessories such as brooches and earrings, advertising pops used in shops, and full-scale paper crafts can be created without being limited to the three examples described above. can do. It can also be used to create signboards and objects to be installed outdoors. Furthermore, depending on the design of the three-dimensional body 5, it can be made for children, adults, or seniors. For example, even at events such as workshops, the fun and joy of making can be experienced without preparing scissors or glue. It can also be made into something.

In addition, since the work sheet 1 described above has a release paper 7 that protects the adhesive surface 12, it is easy to handle in the unfolded state before assembly as shown in FIGS. Even if it is commercialized as a production kit of the base 5, it is easy to store, transport, and display the product.

Although the adhesive surface 12 is formed on the entire back surface of the sheet material 10 as an example above, the adhesive surface 12 may not be formed on a part of the back surface. In that case, the release paper 7 is not required for the portion without the adhesive surface 12 .
