Description

  The present invention relates to a paper fan made of cardboard.

  In the conventional paper fan, the fan leaf and the winding pattern are provided separately, and when used, the winding pattern is inserted by inserting the main part of the winding pattern into the main groove at the lower center of the fan leaf and connecting the two. It is structured to support the lower part of the fan leaf by winding it in three folds. When storing it small, open the winding handle, remove the main pieces, separate them, and wrap them in the three folds on the fan leaf It was a structure with a handle.

JP-A-11-318531

  In the conventional technology, since the fan leaf and the winding handle are separate, it is necessary to separate and connect the main pieces to separate or connect the main pieces. There is a problem in that it is necessary to open the handle, and it takes time and effort to transfer the two forms of folding and storing or opening and using the handle. In the present invention, the problem as described above is solved.

  A fan leaf that is divided into five chambers in the horizontal direction through four folding lines that run vertically to the top and bottom, and that can be folded, is provided with the central chamber of the fan leaf as an axial chamber, and both lateral sides of the axial chamber. A reversing chamber is extended through a reversing folding line, the reversing chamber has a thin fan shape extending in the top direction, and a picking chamber is extended to the lateral outer side of each reversing chamber via a moving folding line. The bottom of the shaft chamber is defined as the shaft bottom, and a shaft hole is formed in a lower region of the shaft chamber. A holding tool is provided as a part for sandwiching and fixing the lower region of the fan leaf from the front and rear, and the holding tool is composed of a front plate and a back plate that are connected to each other via a horizontal holding bottom line. Is inserted into the shaft hole, and both the fan leaf and the holder are fixed. .

  The reversing chamber is reversed by turning over the reversing folding line and turned over so that the moving folding line is drawn toward the axial chamber and overlaps the axial chamber. Has a non-overlapping area where the picking chamber does not overlap, and a shaft hole is located in the unweighted area, and an insertion piece folded from the holding tool is inserted into the shaft hole so that the holding tool is attached to the fan leaf. Since it is fixed to the lower part, it is possible to fold or unfold the fan leaf with the holder attached, so that it is not necessary to attach or detach the holder.

FIG. Example 1 FIG. 10 is a perspective front view of a main part of the other folding state of the fan leaf in a folded state. FIG. It is a holder attachment state principal part perspective front view. It is a holder front view folding state principal part perspective front view. FIG. (Example 2)

  By inserting the insertion piece of the holder into the shaft hole of the shaft chamber and fixing the holder, it was possible to fold and unfold the fan leaf while holding the holder.

  FIG. 1 is a developed front view. The material for producing the present invention may be an artificial resin such as plastic, but is preferably cardboard having an appropriate thickness and hardness, and the thickness and hardness of the cardboard are not limited. It only needs to be changed according to the size of the leaf, and at least it can be handled if it is thicker and more rigid than the official postcard. A solid line is an edge line such as a cutting line, a broken line is displayed as a one-dot chain line, and a perspective line is displayed as a broken line. The folding direction of the fold line can be freely changed by the user, but for the purpose of specifically explaining the contents of the patent, the folding direction is limited and displayed, and the folding direction displayed in the valley fold and mountain fold is viewed from the front. Displayed as a reference, the horizontal direction is horizontal, the vertical direction is vertical, and the front-rear direction is front and back.

  The main body 1 includes a fan leaf 2 and a holder 3, and is fixed in a state where the front and rear of the lower region of the fan leaf 2 are sandwiched by the holder 3. The fan leaf 2 is divided into five chambers in the lateral direction by four fold lines 14 that run vertically in the vertical direction. The center of the chamber is the axial chamber 4, and both sides of the axial chamber 4 are located on both sides. The inversion chamber 6 is extended through the inversion folding line 5. It is desirable that the left side of the inverted folding line 5 be a mountain fold as one inverted folding line 5a, and the right side of the inverted folding line 5 be a valley fold as the other inverted folding line 5b, and the user can arbitrarily change the folding direction of the mountain valley Since it is possible, the direction may be reversed, but both the folding directions are opposite to each other.

  When there are two places with the same sign as in the inverted folding line 5, a sign indicating one and a sign b indicating the other are attached to the right of the sign, and in the drawings, the parentheses are as shown in (a) and (b). If there is no distinction between one and the other, a and b are omitted, and both are collectively referred to.

  One knob chamber 8a is extended through a valley fold through one moving fold line 7a, which is the left side of one inversion chamber 6a extended with one inversion fold line 5a of the shaft chamber 4 as a mountain fold. The other picking chamber 8b is extended through a mountain fold through the other moving folding line 7b, which is the right side of the other inversion chamber 6b extended with the other inversion folding line 5b of the shaft chamber 4 as a valley fold.

  The shape of the fan leaf 2 is not limited, and may be a freely designed shape or a circular shape, but in the case of a fan shape and a fan shape for specific description, The top edge 9 has a substantially (circumferential) circumferential shape, the side edges 10 have two substantially straight radial shapes, and each reference numeral has one side edge 10a and the other side edge 10b. The side edge 10 may be angular, but it is preferable that the corner is properly rounded. The bottom of the fan 2 is aligned with the bottom of the shaft chamber 4 to form the shaft base 11.

  The shape of the shaft chamber 4 is not limited, and may be a vertically long and substantially rectangular or trapezoidal shape, but is preferably a vertically elongated isosceles triangle with the shaft base 11 as the base. At each end of the shaft base 11, the left end is set as one fulcrum 12a and the right end is set as the other fulcrum 12b. A thin fan-shaped chamber that extends almost directly from the one fulcrum 12a is defined as one reversing chamber 6a, and a thin fan-shaped chamber that extends substantially directly from the other fulcrum 12b is defined as the other reversing chamber 6b. And

  A knob chamber 8 is extended on the lateral outer side of the reversing chamber 6 via a movable folding line 7, and the knob chamber 8 is also preferably substantially fan-shaped starting from a fulcrum 12, and has a fan shape. The maximum width of the picking chamber 8 is not limited, but it is a desirable contrast since it is beautiful in design that it is approximately twice the maximum width of the adjacent inversion chamber.

  A shaft hole 13 is formed in a lower region of the axial chamber 4 having a vertically elongated isosceles triangle, and the size and shape of the shaft hole 13 are not limited, but a tunnel-shaped hole of a size capable of inserting an adult thumb without difficulty. If the shaft hole 13 has a tunnel shape, the bottom straight line region is defined as the hole bottom side 23, and the position of the hole bottom side 23 is not limited. It is desirable that the horizontal line at the quarter position be the hole bottom 23. The shaft hole 13 is preferably within the range of the shaft chamber 4. However, the shaft hole 13 is not limited as long as it is located at the lower portion of the fan leaf 2. Although it may be projected up to 6, and even if it is made larger and projected up to the picking chamber 8, there is no functional problem, but there is a problem that the risk of weakening in the case of using a fan increases.

  If the folding folding line 14 is a generic name of the reverse folding line 5 and the moving folding line 7 and the folding leaf 2 does not have the folding folding line 14, it can be fanned without any problems without the holding part 3, but has the folding folding line 14. If the lower region of the fan leaf 2 of the present invention is not reinforced, it will be difficult to fold at the folding line 14 and the fan leaf 2 will not be folded. For the above reasons, it is necessary to attach the holder 3 to the lower part of the fan leaf 2.

  The holder 3 has a structure that is freely designed based on a structure in which a front plate 16 is continuously connected to the top side via a holding bottom line 15 that horizontally crosses the center and a back plate 17 is continuously connected to the ground side. However, it is desirable to have a shape that is bi-folded symmetrically about the holding bottom line 15, and the bi-fold shape is preferably a circular shape with the top and bottom horizontal. The holder 3 is attached by folding the holding bottom line 15 along the bottom of the shaft bottom 11 of the fan leaf 2 in a mountain fold, overlapping the front plate 16 on the front and the back plate 17 on the back. This is performed by sandwiching the front and rear surfaces of the lower region of the fan leaf 2.

  The holder 3 may be provided as a separate tool, but it is preferable that the holder 3 is provided continuously to the lower side of the fan leaf 2. If the above-described continuous structure is specifically described, it is the lower side of the fan leaf 2. The core plate 18 is extended with the shaft bottom 11 as the valley fold line, and the holder 3 is extended with the horizontal core plate wire 19 as the mountain fold line at the leading edge of the core plate 18 extending downward.

  The shape of the core plate 18 is not limited, but may be any shape or size that does not protrude from the overlapping holder 3 and is preferably the same shape as the holder 3 folded in half.

  The core plate 18 is folded upward by folding the shaft bottom 11 on the lower side of the fan leaf 2 to lift the holder 3, and the front plate 16 is overlapped and held in front of the lower region of the fan leaf 2. By folding the bottom line 15, the back plate 17 overlaps the back surface of the lower area of the fan leaf 2, so that the front and rear surfaces of the fan leaf 2 are sandwiched between the holders 3.

  A hole having the same shape as the shaft hole 13 is punched in a state in which the front and rear surfaces of the fan leaf 2 are sandwiched between the holders 3. The holes penetrating through the punching are collectively referred to as finger holes 27, If the finger holes 27 formed by punching are individually described, a core hole 20 is formed in the core plate 18, a front hole 21 is formed in the front plate 16, and a back hole 22 is formed in the back plate 17. Only the back hole 22 is a hole. A line region overlapping the bottom 23 is left as a hinge line 24, an insertion piece 25 is extended through the hinge line 24, and the hinge line 24 is provided as a mountain fold line.

  FIG. 2 is a transparent front view of the main part of the folding fan folded state of the fan leaf. The main body 1 has a structure in which the fan 2 is folded and fixed in a state in which the holder 3 is attached to the lower part of the fan 2, but the holder 3 is illustrated without being overlapped for easy understanding. I will do it.

  The lower end of the other reversing chamber 6b has a long and narrow fan shape starting from the other fulcrum 12b. The uppermost part is the widest, and the widest part is the maximum width.

  By folding the other inversion folding line 5b, the other inversion chamber 6b is inverted and the other moving folding line 7b moves in a circumferential shape centering on the other fulcrum 12b at the lower end. The moving distance of the upper end of 7b is approximately the same as twice the maximum width of the reversing chamber 6b, and the front of the other picking chamber 8b faces the front by folding the other moving folding line 7b. By overlapping the other knob chamber 8b to the front, the shaft hole 13 can be prevented from overlapping the hole bottom 23 region.

  Although the folding state of one reversing chamber 6a and one picking chamber 8a is not shown in the drawing, if described in a sentence, one reversing chamber 6a is reversed by turning one reversing folding line 5a and one moving folding line 7a. Is moved in a circumferential shape centered on one fulcrum 12a at the lower end, and the moving distance of the upper end of the one moving folding line 7a is approximately the same as twice the maximum width of the reversing chamber 6a, By folding one of the movable folding lines 7a, the front surface of one of the knob chambers 8a faces the front, and when the one of the knob chambers 8a is turned back to the front, the shaft hole 13 overlaps the hole bottom 23 region. Can be avoided.

  By avoiding the overlap with the hole bottom 23, the hole bottom 23 becomes the bottom of the non-heavy hole 29 shown in FIG. 5, and the hinge plate 24 is interposed in the region of the back hole 22 of the back plate 17. The extended insertion piece 25 is inserted into the shaft hole 13 so that the fan leaf 2 can be folded or spread while the holder 3 is fixed.

  FIG. 3 is a perspective front view of the main part of the holder attaching process. The core plate 18 shown in FIG. 2 is folded upward by lifting the fold line on the shaft bottom 11 to lift the holder 3, and the holder 3 is lifted and the core plate wire 19 is folded in a mountain. As a result, the front plate 16 overlaps the front of the lower region of the fan leaf 2, and the core hole 20 and the front hole 21 overlap the shaft hole 13 of the core plate 18.

  A hole region overlapping with the shaft hole 13 is defined as a finger hole 27, and an insertion piece 25 is extended to a back hole 22 overlapping with the finger hole 27 via a hinge wire 24. The insertion piece 25 is overlapped with the finger hole 27. The tip region of the insertion piece 25 in a state where the finger holes 27 are bundled is inserted into a kerf 26 cut substantially horizontally into the lower region of the front plate 16 and fixed. In order to facilitate the insertion, it is desirable to insert the auxiliary fold line 28 by a mountain fold line that substantially horizontally crosses the approximate center of the insertion piece 25.

  The holder 3 may be provided separately. However, since the holder 3 is lifted through the continuous core plate 18, the holder 3 can be positioned easily and reliably. The back plate 17 is folded back by folding the holding bottom line 15 in a state along the bottom 11, and both front and rear surfaces of the lower area of the fan 2 are sandwiched by the holder 3.

  FIG. 4 is a perspective view of the main part attached state. The back plate 17 shown in FIG. 3 is folded back to the back by folding the holding bottom line 15 in a state where the front plate 16 overlaps the front of the lower region of the fan leaf 2, and the front and rear surfaces of the lower region of the fan leaf 2. Is pinched by the holder 3, and in order to fix the holding state of the holder 3, the hinge wire 24 is folded and the insertion piece 25 is inserted into the front hole 21 across the hole bottom 23, so that the finger hole 27 is The bundled state of the finger holes 27 is fixed by inserting the tip region of the insertion piece 25 into a cut groove 26 that is horizontally cut into the lower portion of the front plate 16, and the finger holes 27 are fixed. It is also used as a finger insertion hole in addition to the fixing portion of the tool 3, and by inserting a finger into the finger hole 27, the main body 1 can be easily held and gripped, so that it is easy to fan.

  FIG. 5 is a transparent front view of the main part of the holder attached folded state. The insertion piece 25 which fixes the holder 3 penetrates the surface of the fan leaf 2 back and forth, and when the fan leaf 2 is folded, the partial folding region 7 of the finger hole 27 is moved obliquely on both sides. What is the hole area opened by an isosceles triangle with the hinge line 24 as the base because it protrudes from the end but stays at both ends of the hinge line 24 and does not overlap with the spanning area of the hinge line 24? Since they do not overlap, they exist as through holes, and the hole area of the isosceles triangle is referred to as a non-heavy hole 29.

  As will be apparent from the above description, the fan 2 can be folded and unfolded with the holder 3 attached, so that the fan 2 can be opened and closed as in the prior art. There is no need to separate the leaves and rolls every time they are opened and closed.

  Since the holder 3 is fixed by sandwiching the front and rear surfaces of the lower area of the fan 2, it plays a role of reinforcement when the fan is used, and is folded back when the fan 2 is folded. Since the folded folding line 7 that is folded back at both ends of the folded hinge line 24 is snuggled up, the pinching and fixing by the holding tool 3 is strengthened and is fixed securely.

  The through-hole shape of the finger hole 27 in the state in which the fan leaf 2 is folded is an isosceles triangle-shaped non-heavy hole 29 whose base is a hinge line 24, and a hook or the like is hooked on the non-heavy hole 29. Can be hung and displayed.

  FIG. 6 is a front view of the main part of the sheath assembly process in a state of see-through opening. In Example 1, the finger hole 27 was provided in the axial chamber 4 of the fan leaf 2, and the holder 3 was fixed using the finger hole 27. However, in Example 2, the finger hole 27 was not provided, A sheath 33 is provided for the same purpose as that of the holder 3, and the sheath 33 is wrapped around and fixed to the lower part of the fan leaf 32 to form the main body 31 of the second embodiment.

  The folding direction of the mountain or valley fold in FIG. 6 will be described based on the illustrated assembly process rather than the developed view. The sheath 33 is attached by extending the lower portion of the shaft chamber 34 located at the center of the fan leaf 32 downward, and using the stretched region as the shaft plate 48, and the shaft plate line 41 on the lower side of the shaft plate 48. One back plate 47a is extended via a mountain fold line on one lateral side of the front plate 46 that is extended in a mountain fold, and a sheath piece is attached to the outer lateral side of the one back plate 47a via a mountain fold line. 59 is extended, and the other back plate 47b is extended to the other side of the front plate 46 via a mountain fold line, and the center of the other back plate 47b is cut in the vertical direction to provide a sheath groove 60. , The sheath piece 59 is inserted into the sheath groove 60, the one back plate 47a overlapping the other back plate 47b is fixed, and by fixing the other back plate 47b and one back plate 47a, the The sheath 33 is fixed in a state where the lower part of the fan leaf 32 is surrounded.

  The present invention can also be used as a fan without a folding function.
