Description

  The present invention relates to a reinforcing structure of a paper fan and a fixed structure in a folded state.

  The conventional paper fan has three convex fan-shaped fan blades connected in a straight line, the center is the central leaf, and both sides are the side leaves. It was a reinforcement of the overlapping region only, and the folded state was fixed by inserting the end angle of the side leaf into the locking groove opened at the end of the central leaf.

  In the conventional technology, when the fan shape is opened, a single image must be connected on the front and back of the paper.This is not possible with single-sided printing. It is technically difficult to make the darkness the same, and in the case of a catalog, the printing area is small. There was a problem that the end of the leaf was difficult to fix and the end of the locking groove was easily broken. In the present invention, the problem as described above is solved.

  A bag fold line is inserted by a substantially horizontal fold line that penetrates the center of a rectangular substrate of a substantially horizontally long rectangle (almost horizontally long rectangle) in the lateral direction, which is the longitudinal direction, and the central region of the rectangular substrate is a belt, Extending the reinforcing surface through a vertical fold line, and folding the end fold line, the both ends of the band are doubled and reinforced, and the band is divided into approximately three equal parts in the lateral direction. The left ventricle, the middle chamber and the right ventricle are formed as closed lines, which are vertical fold lines, and the belt body and the reinforcing surface are divided into two in a line symmetry with the bag fold line as the center, Each zone of the strip is divided into two areas, and the center of each closed line that is divided into the top and bottom by the bag fold line is a fulcrum. The total number of fulcrums is four, and the fulcrum is the center. The slanted line rotated in the direction toward the middle chamber in the direction in contact with the bag fold line is the closed line, and the fulcrum on one closed line of one (base) belt surface The line leading to the bag fold line is cut to form one cut, the point-symmetric closed line about the center point of the belt is cut to form the other cut, and the bag fold line is folded back. By folding the bag, the band surfaces overlap to form a double-structured horizontal straight band, the right ventricle is folded back to the side having one cut, and the corner of the right ventricle is Insert and fix the left ventricle to the side with the other incision, fold the left ventricular corner into the other incision, fix it, and fold the open line to the left The outer regions of both the chamber and the right chamber protrude below the middle chamber, and both overlap in the protrusion region to form an overlapping region, and a finger hole is provided through substantially the center of the overlapping region.

  Since the band is a substantially oblong rectangle, the edges of the top and bottom are parallel straight lines, so a bag fold line can be formed. By folding the bag fold line, the band has a double structure and is double Therefore, since only an arbitrary surface is the outer surface, both the front and rear sides of the belt are the same surface, and the belt is bent into a Z shape by turning each of the closed lines in a different direction between a valley fold and a mountain fold. Can be folded into a closed shape, and in the closed shape, the upper right corner of the right ventricle is inserted into one incision, and the upper end angle of the left ventricle is also inserted into the other incision on the back. The Z-shaped folded closed state is fixed. By rotating the left and right ventricles downward from the Z-folded state, the refraction of the closed line is released and switching to the folding of the open line, and both finger holes overlap with each other due to the refraction of the open line. Is an open shape assembled in a fan shape, the periphery of the finger hole is a polymerization area where the right and left chambers overlap, and the opening shape is changed by changing the overlapping order of the polymerization areas Since the belt is doubled and only the arbitrary surface is the outer surface, the fan-shaped configuration can be formed only on the same surface. Since the printed surface is free and has a double structure, the entire inner surface can be used as a printed surface as a catalog. The base of the band is a double structure and can be fanned even with the double structure, but it is slightly soft and weak, and the reinforcing surface is folded at both end regions of the band. Therefore, both end regions of the belt body are reinforced with a quadruple structure, and a finger is put into the finger hole and fanned. However, the wind can be efficiently generated by reinforcing the overlapping region around the finger hole.

It is an expanded state inner surface display front view. Example 1 It is the expansion state inner surface display front view which turned up the reinforcement surface. It is a see-through | perspective front view of the principal state in the straightened state extended straight. It is a principal part perspective front perspective view of the state where the belt was folded and closed and fixed. It is the principal part perspective front view before the open state fixation which rotated the both ends of the strip | belt downward. It is a principal part perspective front view after the open state fixation which rotated the both ends of the strip | belt downward.

  Fans can be opened and fixed in the same shape only on the same surface. By reinforcing the periphery of the finger holes that overlap in the open state with a reinforcing surface, it is possible to efficiently create a fan and fix the folded closed state. I realized what I could do.

  FIG. 1 is a front view of the developed state inner surface display. Although the material for manufacturing the main body 1 is not limited, it is desirable that the material is appropriately thick paper. The hardness of the cardboard is not limited, but can be any hardness that is equal to or higher than a government-made postcard. The broken line is displayed as a solid line, the broken line is displayed as a one-dot chain line, the perspective line is displayed as a broken line, and the folding direction of the folding line can be freely selected and changed by the user. For this reason, the bending direction is determined, and the folding direction displayed in the mountain fold and the valley fold is displayed with reference to the outer surface. Basically, the left side is displayed as one side and the right side is displayed as the other side. The other code is displayed using an auxiliary code (b), the parenthesis is omitted in the text, and the above auxiliary codes (a) and (b) are omitted for a comprehensive display.

  The main body 1 is provided with a bag fold line 3 by a mountain fold line penetrating the center of a rectangular substrate 2 having a substantially horizontally long rectangular shape in the lateral direction, which is a longitudinal direction. The planes may be paired, and the top side may be one of the above pairs, but the other side of the pair, which is also the other side, is given an auxiliary code ('). The auxiliary symbols in the drawings are parenthesized, but the parentheses are omitted in the text, and the top side that is the basis is used as a representative for a comprehensive display. A central region of the rectangular substrate 2 is defined as a band body 4, and a reinforcing surface 6 is extended through end fold lines 5 that are perpendicular to both sides of the band body 4. The belt body 4 is divided into a top and bottom with a line symmetry about the center 3, the top side of the bag fold line 3 is a strip surface 7, the ground side is a strip surface 7 ′, and the reinforcing surface 6 located on the left side is One reinforcing surface 6a, the top side divided into the top and bottom in line symmetry about the bag fold line 3 is the reinforcing surface 6a, the paired ground side is the reinforcing surface 6a ', and the reinforcing surface 6 located on the right side is the reinforcing surface 6a. The other reinforcing surface 6b is a symmetrical surface about the bag fold line 3, and the top side divided into two tops and bottoms is the reinforcing surface 6b, the paired ground side is the reinforcing surface 6b ', and the reinforcing surfaces are extended to both sides. The reinforcing surface 6 is folded on both sides of the band 4 by folding both sides of the belt 6 in a mountain fold, and the bag fold line 3 is folded in a mountain fold with the reinforcing surface 6 folded. Thus, the belt surface 7 on the top side is folded back to the front, and the belt body 4 has a double structure. The belt body 4 is a basic shape for forming a fan shape, and the belt body 4 has a double structure. Thus, only the image surface 16 which is an arbitrary selection surface can be made the outer surface, and the printing on the rectangular substrate 2 may be single-sided printing with only the image surface 16 being the front surface, In the case of double-sided printing, it is desirable that the back surface is the catalog surface 17, but free printing that is not a catalog surface is also possible.

  The rectangular substrate 2 is a substantially rectangular shape that is long in the left-right direction, and the central region of the rectangular substrate 2 is defined as a band 4, and the proportion of the band 4 in the region of the rectangular substrate 2 is not limited and is appropriate. However, it is desirable to occupy a ratio of about 75%, and the shape of the band body 4 is not limited, but is preferably a horizontally long rectangle with rounded corners. The shape of the reinforcing surface 6 extending through 5 is not limited, but it is desirable that the shape is slightly smaller than the shape of the end region in the lateral direction of the band 4.

  FIG. 2 is a front view showing the inner surface of the unfolded state where the reinforcing surface is folded back. The band 4 is bisected into the top and bottom by a bag fold line 3 that crosses the center in the lateral direction, which is the longitudinal direction, and the bisected area is a band surface 7 based on the top side, and the ground side is the base band. Let it be a band surface 7 ′ which is a pair of the surfaces 7. The strip 7 on the top side is divided into three chambers by dividing it into three parts in the transverse direction, which is the longitudinal direction, and extends to the right side of the left chamber 11 at the left end via one closed line 8a. The right chamber 13 is extended to the right side of the middle chamber 12 via the other closed line 8b. The center of one closed line 8a is one fulcrum 9a, one open line 10a is provided by a fold line rotated to the left about the fulcrum 9a, and the center of the other closed line 8b is the other fulcrum 9b. The other open line 10b is provided by a broken line rotated to the right about the fulcrum 9b. The cut 14 is made in one of the two open lines 10, but it is preferably provided on one open line 10a located on the left side, and one fulcrum 9a on one open line 10a located on the left side. To the bag fold line 3 and cut one of the cuts 14a.

  The ground-side belt surface 7 'is divided into three chambers by dividing it into three parts in the transverse direction, which is the longitudinal direction, and extends to the right side of the left chamber 11' at the left end via one closed line 8a '. The right chamber 13 'is extended to the right side of the provided middle chamber 12' via the other closed line 8b '. The center of one closed line 8a 'is set as one fulcrum 9a', and one open line 10a 'is provided by a broken line rotated to the right about the fulcrum 9a', and the center of the other closed line 8b 'is set as the other The other open line 10b 'is provided by a broken line that is rotated to the left about the fulcrum 9b'. A cut 14 is made in one of the two open lines 10 ', but it is preferable to provide the cut 14 on the other open line 10b' located on the right side, and the other on the other open line 10b 'located on the right side. From the fulcrum 9b 'to the bag fold line 3, the other notch 14b is inserted. The positional relationship between the one notch 14a and the other notch 14b is provided point-symmetrically with the center point of the band 4 as the midpoint.

  FIG. 3 is a perspective front view of the main part in the straightened state, which extends straight. Although the band 4 is illustrated with a single surface, the substance has a double structure in which the base band surface 7 located in the top region from the bag folding line 3 is folded back and folded into the front. The both end regions of the body 4 have a quadruple structure because the reinforcing surface 6 is folded, and the reinforcing surface 6 is located in the bag body 4 that is folded in a bag. Show. 4, FIG. 5, and FIG. 6, which will be described later, are double-folded, and both end regions of the band 4 have a quadruple structure in which the reinforcing surface 6 is folded. Only the base band surface 7 can be illustrated from the front in the straightened state, but the pair of band surfaces 7 ′ are hidden in a folded state on the back surface, and only the band surface 7 illustrated on the front side is labeled. The name will be stated.

  In the folded state, the top side of the band 4 is the top edge 18 and the ground side is the ground edge 19, the top edge 18 is the bag fold line 3, and the belt surface 7 ′ is line-symmetrical via the bag fold line 3. 1 and 2, the belt surface 7 ′ may be extended with the ground edge 19 as the bag fold line 3.

  In the case of the belt body 4 having a double structure by folding the bag fold line 3, if the front belt surface 7 is folded, the rear belt surface 7 ′ is inevitably mountain-folded. Is represented by the band 4, and thereafter, it is displayed in a mountain or valley fold with reference to the front direction, and the bending direction of the band surface 7 'is omitted.

  The bending direction of one closed line 8a and the other closed line 8b can be freely selected by the user. However, in order to clarify the explanation of the patent contents, the two closed lines are defined. It is desirable to bend in a different direction, and if one closed line 8a is a mountain fold, the other closed line 8b is desirably a valley fold.

  If one closed line 8a is a mountain fold, one open line 10a intersecting at one fulcrum 9a is also a mountain fold, and if the other closed line 8b is a valley fold, the other open line 10b intersecting at the other fulcrum 9b is also Make a valley break.

  By positioning one open line 10a around the one fulcrum 9a to the position where it is rotated and moved to the right, a right-angled triangular region is formed symmetrically with the closed line 8a on the top and bottom of the fulcrum 9a, In the right triangle region, the top side of one fulcrum 9a is the top inversion region 20a and the ground side is the ground inversion region 21a.

  By positioning the other open line 10b around the other fulcrum 9b to the position where the other open line 10b is rotated to the left, a right triangle region is formed symmetrically with the other closed line 8b on the top of the fulcrum 9b, In the right triangle region, the top side of the other fulcrum 9b is a top inversion region 20b and the ground side is a ground inversion region 21b.

  FIG. 4 is a perspective front perspective view of a main part in a state where the belt body is folded and closed and fixed. The closed state is a state in which the bellows is folded into a Z-shape (including a Z-shape reversed to the left and right) and is held only in the bellows-folded state, but is unstable and may be released after the bellows-fold is released. Since the right end of the belt 4 is folded back to the front, the pair of right chambers 13 'hidden behind the back appears to the front, and the upper end of the other end fold line 5b' which is the upper end corner region of the right chamber 13 ' The right chamber 13 'is fixed by being inserted into the notch 14a, and the upper left corner of the left chamber 11 is also inserted into the other notch 14b in the same manner as the fixing of the right chamber 13'. The upper end of one end fold line 5a which is a region is inserted and fixed. When opening in a fan shape, the finger is inserted into the finger hole 15 and the right chamber 13 and the left chamber 11 extended on both sides of the middle chamber 12 are rotated and slid downward to close the fulcrum 9 as a closed line. When the refraction of 8 is switched to the refraction of the open line 10, the band 4 is opened. The size of the band 4 in the closed state after being folded into a Z shape is not limited, and may be appropriate. However, the band 4 is folded to a width that is appropriately narrower than the width of a breast pocket such as a shirt or a suit. It is desirable that the band 4 is used.

  FIG. 5 is a perspective front view of the main part before fixing the open state in which both ends of the belt body are rotated downward. The main body 1 picks up one finger hole 15a of the left chamber 11 that is folded back with the left hand from the closed state of FIG. 4 and pulls it to the left, and the other finger hole 15b of the right chamber 13 that is folded back with the right hand to the front. By picking up and pulling it to the right, both ends of the belt body 4 rotate downward to be in a fan-shaped open state. This is because the refraction is switched from the closed line 8 intersecting around the fulcrum 9 to the open line 10 in the structure that allows the downward rotational movement.

  The rotation angle of the rotational movement may not be limited, but is preferably a rotation angle at which the center of the top edge 18 in the region of the right ventricle 13 and the center of the ground edge 19 in the region of the middle chamber 12 intersect each other, The crossing point at the center of both the centers is the umbilical point 22, the angle of the celestial reversal area 20 adjacent to the fulcrum 9 is the reversal angle 23, and the angle of the reversal angle 23 is half the rotation angle of the right ventricle 6. The thigh point 22 becomes a crossing contact. The rotational movement of the right chamber 13 is performed point-symmetrically around the umbilical point 22, and the state where one finger hole 15a and the other finger hole 15b overlap each other is used as a mark. The rotational movement can be guided to the correct position.

  The outer end regions of the right chamber 13 and the left chamber 11 overlap below the navel point 22, and the overlapping region is a superposition region 24, and the finger hole 15 penetrates substantially (approximately) the center of the superposition region 24. Has been.

  FIG. 6 is a perspective front view of a main part after the open state is fixed by rotating both ends of the belt downward. In FIG. 5, the band 4 is only folded into a fan shape so that it is in a state before fixing, and the right chamber 13 which is the other end region is folded to the front. By replacing the left chamber 11 with the right chamber 13 folded forward, the right chamber 13 is hidden behind the polymerization chamber 24, and the left chamber 11 exits the front to Fixed in place.

  In the band 4 assembled in a fan shape, only the middle chamber 12 is a base band surface 7 which is a front region, and the left chamber 11 and the right chamber 13 extending on the left and right sides of the middle chamber 12 are rear surfaces. A pair of band surfaces 7 ′, which are regions, face the front. If the strip 4 is a single layer, the front and back surfaces of the paperboard face each other and face the front, but the strip 4 is formed in a double structure folded by a bag fold line 3 so that the image on the front surface is formed. Only the surface 16 is the outer surface, and the catalog surface 17 that is the back surface is hidden behind the bag-folded inner surface.

  As shown in FIG. 6, when the main body 1 is fanned in the state of being opened and fixed, a finger (thumb) is inserted into the finger hole 15 to grip the grip area 25 which is the area below the finger hole 15. Since it has a structure, a bending force is applied to the periphery of the finger hole 15, and the overlapping region 24, which is the peripheral region of the finger hole 15, is reinforced by folding the reinforcing surface 6. Since the periphery of the hole 15 is hard and difficult to bend, it can be fanned without hindrance and the wind can be made efficiently.

  Since the present invention has a two-layer structure with a substantially rectangular basic shape, it can be used as a catalog fan and catalog fan with the back surface folded on the inner surface as a catalog display surface, and can also be used as a direct mail, greeting text, etc. It can also be used as a summer greeting to fill in, or as a tourist information map.
