Description

  The present invention relates to a fan, and more particularly, to a fan used suitably for an appendix such as a magazine, a toy, a premium, and the like.

  Fans are used to obtain coolness in the summer when the temperature is high, but in recent years they have become an important item as a tool for new product sales and events. Such tools tend to get bored quickly, and there is a demand for tools that can enjoy new design and surprisingness and contribute to sales promotion activities.

  Therefore, the present applicant has already published Japanese Laid-Open Patent Publication No. 2004-77548 (Patent Document 1) with a fan (fan 1) with a specification in which paper is pasted on the front and back of the framework. The invention has been proposed in which information 13 is provided, a window hole is provided in a part of the fan body 11, and a Fourier transform lens 15 is fixed to the window hole.

  According to the present invention, it can be used as a fan, and at the same time, when a fan is raised with respect to a point light source (fireworks) at a fireworks display etc. and the point light source (fireworks) is viewed through the Fourier transform lens 15, the image appears to be raised Therefore, when many users (fireworks spectators) raise the fan, the printed information 13 on the surface of the fan body 11 is raised, and it can be expected to perform functions such as advertising.

Japanese Patent Laid-Open No. 2004-77548

  However, in order to maintain the fan function of the fan, the fan has a handle, a plurality of spoke portions that radiate from the upper end of the handle, an end of the plurality of spoke portions, and an upper end of the handle. There is a need for a framework with an annular portion that connects in an annular fashion.

  On the other hand, in order to more effectively exhibit the function of the Fourier transform lens, that is, the function that the image appears when the point light source is viewed through the Fourier transform lens, it is desirable that the area that shields the Fourier transform lens is small.

  Then, in order to effectively exhibit the function of the Fourier transform lens, it is preferable that the frame hole and the spoke portion of the frame do not exist in the window hole, but this leads to a decrease in the fan function of the fan. In this respect, the fan described above has a problem in that the function of the fan of the fan and the optical function of the Fourier transform lens are contradictory.

  In addition, the fan described above requires special manufacturing equipment, and since the Fourier transform lens is expensive, there is a problem in cost that the unit price of the fan increases.

  In order to solve the problem of the fan having the conventional optical function, the present invention aims to provide a fan that can reduce both the unit fan's original fan function and the optical function of the Fourier transform lens and can suppress the unit price. To do.

According to a first invention for achieving the above-described object, printing is performed on both sides of a rounded rectangular main body formed by bonding two base materials, which are paper materials, and a hole is formed in the main body. A fan provided with a Fourier transform lens sandwiched between the base materials and arranged in the hole, and on the four sides excluding the corners, the two base materials are aligned, At least one of the four corners, the two base materials are misaligned, a finger hole for passing a finger through the main body is provided, and the direction connecting the finger hole and the hole is the base material The bending strength of the base material in the paper direction is greater than the bending strength of the base material in the direction perpendicular to the direction connecting the finger holes and the holes, and either of the main bodies The hole formed in the base material is larger than the hole formed in another base material. It is fan characterized by.

  Since the structure of the fan according to the present invention is a specification that does not have a framework, the fan function of the fan and the optical function of the Fourier transform lens can be achieved. In addition, since one Fourier transform lens is provided between the base materials, material costs other than the Fourier transform lens are low, and the unit price of the fan can be suppressed. Furthermore, even if there is a manufacturing error, the base material can be easily peeled off due to the misalignment of the corner, and the Fourier transform lens can be taken out and reused. In addition, since it is possible to manufacture on the production line that forms the forms of correspondence, envelopes, forms, etc. possessed by the printing company, Unit price can be reduced.

In the present invention, the body Aogu it is easier to have a more fan on and this finger hole for passing the fingers is provided, is highly convenient.

Moreover, an adhesive agent is apply | coated to any one said base material, Two said base materials are bonded together by superimposing said one base material on the other base material, Two said base materials are attached. When peeled, it is desirable that the amount of the adhesive attached to the one base material is larger than the amount of the adhesive attached to the other base material.
The fan of the present invention can be easily formed by applying an adhesive to one of the substrates by printing or the like, overlaying the other substrate, and pasting the substrates together. At this time, when the substrate is peeled off, the amount of the adhesive that adheres to the one substrate increases.

The second invention is the first hole, the second hole at positions symmetrical with respect to the center line on both sides of the center line of the base material, which is a paper material printed on one surface, Four arc-shaped cuts that swell toward the outside of the periphery of the first and second holes are formed, and Fourier transform is performed so as to cover any one of the first holes on the other surface of the base material. Attaching a lens, on the other surface of the base material, apply an adhesive to either one of the sides of the center line, fold back the base material at the center line, and bond the other surfaces together, The bonded base material is cut by four linear cut lines connecting opposite ends of the cut, and the grain direction of the base material connects the first hole and the second hole. a direction, the bending strength of the base material in the paper grain direction is a second hole and the first hole Greater than the bending strength of the substrate in a direction perpendicular to the direction connecting the one of the first hole in a symmetrical position with respect to the center line, one of said first holes, another of said first It is a fan manufacturing method characterized by being larger than the hole.

  According to the present invention, it is possible to provide a fan that can achieve both the fan function of the fan and the optical function of the Fourier transform lens, and can suppress the unit price.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment]
(1 fan 1)
First, a fan according to a first embodiment of the present invention will be described with reference to FIG. FIG. 1A is a view showing a table of the fan 1, and FIG. 1B is a view showing the back of the fan 1. FIG. 1C is a cross-sectional view taken along line AA in FIG.

  In the fan 1, two base materials 11 are stacked and bonded to form a main body 10 having a rounded rounded rectangular plane. The main body 10 is provided with a window hole 10a and a finger hole 10b, and a pattern 10c, a character 10d, and the like are printed on both surfaces.

The base material 11 is, for example, a paper material. If the amount of paper is about 157 g / m ² , the strength of the fan 1 can be suitably secured.

  In the fan 1, the two base materials 11 are bonded together in position, and the upper and lower base materials 11 are aligned on the four sides excluding the corner portions, but at least one corner portion is aligned with the upper and lower base materials 11. There is a displacement 10e. In the example shown in the figure, there is a positional deviation 10e at two corners.

  The window hole 10 a is for viewing the other side of the fan 1. A Fourier transform lens 13 is provided in the window hole 10a. The Fourier transform lens 13 is disposed with the lens outer peripheral portion sandwiched between the base materials 11.

  When the point light source is viewed through the lens, the Fourier transform lens 13 is an image that appears due to the unevenness formed on the lens, and is formed of a resin film such as PET (polyethylene terephthalate). Details of the Fourier transform lens 13 are described in Japanese Patent Application Laid-Open No. 2004-77548, and detailed description thereof is omitted here.

  The finger hole 10b is a hole for letting a finger pass through the main body 10, and this makes it easy to carry the fan with the fan 1.

(2. Manufacturing method of fan 1)
Next, a method for manufacturing the fan 1 will be described with reference to FIGS.

  In this embodiment, as shown in FIG. 2A, first, the web-like base material 11 is unwound from a roll (not shown) and conveyed, and a cutting device such as a cutter handles the conveyance direction (corresponding to the vertical direction in the figure). Cut along the width direction orthogonal to The base material 11 after cutting is shown in FIG.

  Note that pin holes 111 into which base material transport pins (not shown) are inserted are provided at both ends of the base material 11 in the width direction, and perforations 112 are formed at the center in the width direction along the transport direction. (Center line) is provided. Further, in FIG. 2A and the like, the pattern 10c and the characters 10d are printed on the surface (one surface) of the base material 11 which is not shown. On the illustrated side surface (the other surface), application of an adhesive which will be described later, adhesion of the Fourier transform lens 13 and the like are performed.

  Returning to the description of FIG. In the present embodiment, subsequently, as shown in FIG. 2C, the base material 11 is punched out by a punching device such as a punch, and the holes 113 are formed at positions symmetrical with respect to the perforation 112 on both sides of the perforation 112. 114 and the notch 115 are formed. Four cuts 115 are provided around the holes 113 and 114, and have an arcuate shape of approximately 90 ° that bulges outward.

  The holes 113 and 114 are for forming the window hole 10a and the finger hole 10b, respectively. The vertical direction connecting the hole 113 and the hole 114 (the vertical direction of the fan 1) is the above-described web-like base. It is set according to the conveying direction of the material 11. This direction is also referred to as the grain direction and has a higher strength against bending than the width direction. Therefore, when the vertical direction of the fan 1 becomes the grain direction, the rigidity in the vertical direction of the fan 1 is improved, and when the fan 1 is fanned by holding the fan 1 at the finger holes 10b and swinging the vertical direction back and forth. Wind can be suitably generated and coolness can be obtained.

  When forming the hole 113, one hole 113 is formed slightly larger than the other hole 113 in order to make the positional deviation of the base material 11 around the hole 113 at the time of bonding the base material 11 to be described later inconspicuous. Is also possible.

  When the holes 113 and the like are formed in the base material 11 as described above, an adhesive is then formed around the holes 113 on one side of the perforation 112 as shown in FIG. 116 is applied. The adhesive 116 is for attaching the Fourier transform lens 13 made of resin. For example, a water-based acrylic paste can be used.

  Thereafter, as shown in FIG. 3B, the Fourier transform lens 13 is pasted on the base material 11 so as to cover the hole 113 by a pasting device.

  Then, as shown in FIG. 3C, an adhesive 117 is applied to the base material 11 on one side of the perforation 112. The adhesive 117 is used to bond the base materials 11 together. For example, EVA (ethylene-vinylacetate copolymer) based aqueous paste can be used. The adhesive 117 is applied in a dot shape by printing or the like, and a clearance is provided between the application region and the perforation 112.

  Thereafter, both ends in the width direction of the base material 11 having the pin holes 111 are cut off by a cutting device such as a cutter as shown in FIG.

  Next, as shown in FIG. 4B, the base material 11 is folded back by the perforation 112 by the folding device, and the base materials 11 on both sides of the perforation 112 are overlapped with each other as shown in FIG. Match. At this time, the positions of the holes 113 and 114 on both sides of the perforation 112 correspond to form the window hole 10a and the finger hole 10b of the fan 1 described above, respectively.

  Then, with a cutting device such as a cutter, as shown in FIG. 4C, four linear cut lines 118 connecting the outer peripheral portions of the bonded base material 11 to the opposite end portions 115 a of each cut 115. Cut along. In FIGS. 4B and 4C, the display of the pattern 10c and the characters 10d is omitted.

  As described above, the base material 11 is cut by the cut line 118 and the cut 115, and the fan 1 shown in FIG.

  Each processing described above can be realized in a form processing manufacturing line owned by a printing company that performs processing such as windowing, pasting, and cutting of correspondence, envelopes, forms, and the like. That is, the fan 1 can be manufactured on the foam processing manufacturing line.

  Further, the four corners of the fan 1 are rounded from the viewpoint of safety, but it is difficult to cut the rounded rectangular shape at a time. Therefore, in the present embodiment, the round-corner rectangular fan 1 is manufactured by first providing the arc-shaped cuts 115 at the four corners, and cutting the cut line 118 after bonding the base material 11 together.

  In this case, when the base material 11 is bonded in FIG. 4B, the base material 11 is slightly displaced due to the lift of the base material 11 due to the adhesive 117. The end portions of the base material 11 are finally aligned by cutting the base material 11 with the cutting line 118 at the portions other than the four corners of each side of the fan 1. However, the cut 115 is formed before the base material 11 is bonded. Therefore, the displacement 10e remains at the four corners of the fan 1. When the defective product is generated in the fan 1 due to the positional deviation 10e, there is an advantage that the upper and lower base materials 11 are opened and peeled off, and the expensive Fourier transform lens 13 can be reused. When the base material 11 is peeled off, the amount of the adhesive 117 attached to the base material 11 to which the adhesive 117 is applied is larger than that of the other base material 11.

  As described above, the structure of the fan 1 according to the present embodiment is a specification that does not include a framework, so that the fan function of the fan and the optical function of the Fourier transform lens 13 can be compatible. Moreover, since it is the structure which provided the one Fourier-transform lens 13 between the base materials 11, material costs other than the Fourier-transform lens 13 are cheap, and the unit price of the fan 1 can be suppressed. Further, even when there is a manufacturing error, the base material 11 can be easily peeled off by the corner misalignment 10e, and the Fourier transform lens 13 can be taken out and reused. In addition, since it is possible to manufacture on the production line that forms the forms of correspondence, envelopes, forms, etc. possessed by the printing company, Unit price can be reduced.

  Moreover, since the finger hole 10b for letting a finger pass through is provided in the main body 10, it becomes easy to carry the fan with the fan 1 and is highly convenient.

  Furthermore, in this embodiment, the adhesive 117 is applied to one base material 11 and the base materials 11 are bonded to each other so as to be overlapped on the other base material 11, whereby the fan 1 can be easily formed. At this time, when the base material 11 is peeled off, the amount of the adhesive 117 attached to the one base material 11 becomes larger than the amount of the adhesive 117 attached to the other base material 11.

[Second Embodiment]
Next, an example of a fan of the second embodiment will be described with reference to FIG. The second embodiment will be described with respect to differences from the first embodiment, and the description of the same will be omitted.

  A fan 1a shown in FIG. 4 (a) has a main body 10 having a substantially rectangular shape with rounded corners and a circular window hole 10a. This fan 1a can also be manufactured in the same manner as in the first embodiment, and the same effect as in the first embodiment can be obtained.

  Thus, the shapes of the main body 10, the window hole 10a, and the finger hole 10b can be variously determined in consideration of the design of the fan and the fan function. Moreover, as shown in the fan 1b of FIG.4 (b), it is also possible to abbreviate | omit the finger hole 10b.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention.
