  The traditional fan with a handle is provided with a fan leaf and a roll handle separately. When using a fan, insert a core piece into the main groove at the lower center of the fan leaf and connect them together. Is folded in three folds to support the lower part of the fan leaf, and when storing small, open the winding handle, remove the main pieces, separate them, and fold the fan leaf into three folds It was a structure with a wound pattern.

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 that it is necessary to open the handle, and it takes time and effort to shift between the two forms of storing and using. In the present invention, the problem as described above is solved.

  A handle protrudes under the fan leaf that can be opened and closed by the opening and closing part, and a sheath part opposite to the top and bottom is extended to the lower end of the handle via a horizontal base fold line, and the base fold line is moved upward to a parallel translation point. A folding line is inserted, and a region sandwiched between the step folding line and the base folding line is used as a storage stage, and the sheath is lifted by folding the base folding line so that the top and bottom are in a normal positional relationship. The lower part of the open fan leaf can be supported by winding the overlapped handle on the sheath portion, and the fan leaf closed at the opening / closing portion is pushed toward the sheath portion. The folding line is bent and the storage stage is inverted around the base folding line, and the tip area of the handle is folded and shortened by reversing the storage stage, which is the tip area of the handle, so the fan leaves into the sheath. It becomes the structure where is stored.

  Because the sheath part opposite to the top and bottom is extended through the base folding line to the tip of the handle that protrudes to the lower part of the fan leaf, the fan leaf and the sheath are integrated, so the main part of the prior art is inserted and removed The fan can be opened and closed with the opening and closing part while the sheath is wrapped around the handle, and can be stored in the sheath with the folded fan leaf wrapped, so the main body can be stored and used. These two forms can be easily transferred.

FIG. Example 1 It is a principal part perspective rear view of an open state assembly process. FIG. FIG. (Example 2) It is a see-through | perspective back view of an opening state assembly process principal part. It is a principal part see-through | perspective back perspective view of the front stage which closes and accommodates.

  The fan leaf and the sheath were integrated, and the fan leaf was opened and closed with the sheath wound, and the fan leaf was closed and stored in the sheath.

  FIG. 1 is a developed rear view. The positional relationship between the front and back may be arbitrary, but we want to assemble with the front surface of the sheath part as the outer surface, so we will show it based on the back view, the perspective line is displayed with a broken line, and the broken line is one point The user can change the folding direction of the fold line as indicated by the chain line, but it is necessary to determine the fold direction in order to specifically explain the patent contents. Based on the above, the solid line is displayed as a separate line, and the material of the main body 1 is not limited, and may be a plastic plate, but it is made of appropriately thick cardboard that is equivalent to or slightly harder than a government-made postcard It is desirable.

  The main body 1 is composed of a single fan leaf 2, a handle 5, and a sheath 3, and the shape of the fan leaf 2 is not limited and is a freely designed shape, but the description will be made concrete. For this purpose, a fan shape is illustrated, and two folding lines that divide the fan leaf 2 into approximately three equal parts are inserted, and the two folding lines serve as an opening / closing part 4, and the area sandwiched between the opening / closing part 4 If the fan leaf 2 is fan-shaped, it is desirable that the middle leaf region 7 sandwiched between the opening and closing portion 4 that divides the fan leaf 2 into three parts is also fan-shaped with a small opening angle. The pattern 5 protrudes downward with the same width as the width of the lower end of the middle leaf area 7 that becomes narrower and does not have a line separating the fan leaf 2 and the handle 5. From the place where the left and right side edges are parallel, the bottom is the handle 5 and the bottom 5 is extended to the bottom edge of the handle 5 through the base folding line 6 which is a horizontal valley folding line. .

  Since the sheath 3 in FIG. 1 is shown upside down, the bottom is the top of the sheath 3, and the shape of the sheath 3 is a fan shape with a small opening angle that is trifolded in the left-right direction and widened in the top direction. The standard for determining the size of the opening angle is not limited, but 45 degrees is the center, and the central region of the sheath portion 3 divided into three by the fold line to be folded in three is used as the inner sheath 8, a region extending to one side of the inner sheath 8 via a valley fold line is referred to as a sheath 9, and a region extending to the other side of the inner sheath 8 via a valley fold line is referred to as b sheath. The a-sheath 9 has a shape approximately the same width as that of the middle sheath 8 above the base folding line 6 (below it is upside down in the figure), and a kerf 11 is formed on the centerline of the top-and-bottom, and the center of the b-sheath 10 is formed. A region protruding to the other side through the valley fold line placed on the line is referred to as an insertion piece 12.

  The horizontal lower end of the handle 5 protruding downward from the center of the fan leaf 2 is a base fold line 6, and a step fold line 13 is provided as a valley fold line to the position where the base fold line 6 is moved in parallel upward, A region sandwiched between the fold line 6 and the stepped fold line 13 is defined as a storage step 14, and the region of the storage step 14 may be a single surface that does not have a fold line. It is desirable to insert a fold line 15, and the interval between the fold lines 15 may be equal, but it is desirable to shorten the interval as the fold line 13 approaches the base fold line 6. May be one or two, but is shown in two, and the shape of the handle 5 may be a rectangle with both lateral edges parallel to each other. A shape that is constricted at the position of the interfold line 15 (the lowermost interline line) is desirable.

  FIG. 2 is a perspective rear view of the main part in the open state assembly process. By folding the base fold line 6 in a valley fold, the top of the sheath 3 is lifted upward and the top of the sheath 3 is in a normal positional relationship, the inner sheath 8 and the handle 5 overlap, and the a sheath 9 and b By bending the sheath 10, the sheath portion 3 is folded in three and wound around the handle 5, and the sheath portion 3 in the wound state supports the lower region of the open fan 2. As a result, the fan leaf 2 can be fanned without glaring.

  The reason why the drawing of the present invention is a rear view is that it is desired to wind with the front surface of the sheath 3 as the outer surface and to display the base fold line 6 which is the main part of the patent contents. The center line of the inner sheath 8 and the cut groove 11 on the center line of the a sheath 9 are overlapped with respect to the vertical line at the center of the handle 5, the b sheath 10 is overlapped on the a sheath 9, and the insertion piece 12 is the cut groove. 11, the winding state of the sheath 3 is fixed, and since the fold line of the base of the insertion piece 12 and the kerf 11 are located on the same line, the insertion of the insertion piece 12 is easy. And the inserted state is fixed.

  In addition to inserting the insertion piece 12, the kerf 11 also has a role of assisting inversion of the storage stage 14, and the storage stage 14 is inverted around the base fold line 6. The ridges 11 are raised and the cuts 11 break and widen, so that the ridges can escape. In order to play the above escape role, it is necessary to extend the kerf 11 below the base fold line 6, and the a sheath 9 which is the base of the kerf 11 is extended below the base fold line 6, By providing the extension region, the kerf 11 can be extended. The shape of the extension region may be square, but is preferably semicircular.

  The folding direction of the opening / closing part 4 which is a fold line structure may be folded in the user's favorite direction, but it is unified by valley folding, and the fan leaf 2 is moved into the region of the middle leaf area 7 by folding the opening / closing part 4 Even when the sheath 3 is folded and closed, the fan leaf 2 can be folded and closed or opened, and the fan 2 can be closed to support the sheath 3 in the wound state. It can be released and the fan leaf 2 is ready to be stored in the sheath 3 in the wound state.

  In order to store the fan leaf 2 in the wound sheath 3, the handle 5 must be able to move downward, the lower region of the handle 5 is set as a storage step 14, and the storage step 14 is a base fold line. The handle 5 can move downward by reversing around the center 6, and the storage step 14 is in the range from the upper step fold line 13 to the lower base fold line 6, and the storage step 14 is divided into one section plane. In this case, a large bulge is generated at the time of reversal, so that the reversal function of the kerf 11 can not be reversed and the reversal cannot be reversed. Therefore, it is desirable to insert the fold line 15 with a horizontal valley fold line translated from the base fold line 6. The number of fold lines 15 is not limited, and may be adjusted according to the top and bottom length of the storage stage 14. In the present application, two fold lines 15 are illustrated, and the intervals between the fold lines 15 are equal. The interval from the step fold line 13 to the base fold line 6 may be continuous. It is desirable to shorten.

  The reason why the interval between the fold lines 15 is continuously shortened from the step fold line 13 toward the base fold line 6 is that it is reversed from a region close to the base fold line 6, and the region divided into the top and bottom by the interline fold line 15 is the base portion. Since the section area close to the fold line 6 is short, it can be reversed with a small force because it bulges small, so there is less burden on the kerf 11, and as the storage step 14 protrudes downward from the base fold line 6, Since the pressure is reduced, even a long divided area can be reversed without difficulty. Since the lowest fold line 15 closest to the base fold line 6 is shortened and constricted, the raised ridge line is shortened. By shortening the raised ridge line, the crack spread of the kerf 11 is reduced, so the burden can be reduced.

  FIG. 3 is a perspective rear view of the main part of the storage state. Since the fan leaf 2 that is closed by folding both sides of the opening / closing portion 4 is within the range of the middle leaf region 7, the fan leaf 2 has a width that can be accommodated in the wound sheath portion 3, and is large enough to accommodate the entire fan leaf 2. The sheath 3 may be provided. However, if the sheath 3 is made the above-mentioned size, the sheath 3 becomes too large as a contrast balance when the fan 1 is opened and the main body 1 is used. Since it is too difficult to grip, it is desirable that the lower half of the fan leaf 2 be accommodated.

  The storage of the fan leaf 2 in the sheath 3 is completed with all of the storage steps 14 coming out below the base folding line 6, and the storage step 14 is inverted around the base folding line 6. The fan 2 is moved up and down (top and bottom) by twice the length of the step fold line 13 and the base fold line 6, or in other words, twice the top and bottom length of the storage step 14. Therefore, the middle leaf area 7 having the same shape as that of the fan leaf 2 is closed is shaped so as to be accommodated with approximately the same width as the upper ends of the inner sheath 8 at the position where it has finished moving downward. It is desirable.

  FIG. 4 is a developed rear view. In Example 2, the fan leaf 22 is provided by two pieces of A leaf 23 and B leaf 24, and the A leaf 23 and B leaf 24 are in a symmetrical relationship with respect to the left and right lines around the handle 25. The opening / closing part 4 that opens and closes the fan leaf 22 is a reversing fan portion 27a, 27b, and the fan leaf 22 is switched by refraction of the open folding lines 26a, 26b and the closed folding lines 29a, 29b with the lower end as a base point. The two have a structure that can be rotated and moved in opposite directions to overlap each other and close or disengage and open, and an extended structure that extends from the lower end of the handle 25 via a horizontal base fold line 6. The sheath 3 is preferably provided with the same structure and shape as in the first embodiment.

  In Example 1, the fan leaf 2 was extended without the dividing line at the upper end of the handle 5, but in Example 2, the fan leaf was turned to the left and right sides of the upper portion of the handle 25 via the inverted fan areas 27a, 27b. 22, the upper end of the handle 25 is an edge that is not extended at all, and an open line 26a is formed on one side of the upper portion of the handle 25. The reversing fan part 27a is extended, and the shape of the reversing fan part 27a has a fan shape with the lower end as a base point 28a, and the A leaf 23 is extended to one side of the reversing fan part 27a via the closed folding line 28a. The structure extending to the other side of the upper part of the handle 25 is also provided in line symmetry with the structure extending to the one side, and the line-symmetrical locations correspond in the order of one and the other from the side closer to the handle 25. In other words, the folding line 26a and the folding line 26b, the reversing fan part 27a and the reversing fan part 27b, and the base point 28a. Base 28b, 閉折 lines 29a and 閉折 line 29 b, A leaf 23 and B leaves 24, and becomes.

  FIG. 5 is a transparent rear view of the main part of the opened assembly process. The folding direction of both fan leaves 22 can be arbitrarily changed by the user, but the folding direction is unified for the purpose of clarifying the explanation of the patent contents, and the conventional fan has a structure that opens the front side to the right side. By folding the left open fold line 26b, which is the other side of the handle 25, in a valley fold, the B-leaf 24 is reversed to the back, which is the front, and stays in the open position shifted to the right. By folding the bag in a mountain fold, the A leaf 23 reverses in the front direction and stays in the open position shifted to the left, and the A leaf 23 and the B leaf 24 remaining in the open position partially overlap, The overlapping region is defined as a polymerization zone 30, and the open state of the fan leaf 22 can be fixed by replacing the overlap of the polymerization zone 30 before and after, and the base folding line 6 is folded in the same process as in Example 1 to form a sheath. The sheath 3 with the handle 25 as the core by lifting the part 3 Can support the lower state of fanning leaf 22 opens by winding a.

  FIG. 6 is a perspective rear perspective view of the main part in the previous stage of closing and storing. The reason that only FIG. 6 is a perspective view is to illustrate the overlapping state of the fan leaves 22. When the B leaf 24, which is shifted to the right and pushed to the left, is pushed to the left, the refraction of the left folding line 26b of the handle 25 that has been refracted in the open state is canceled and switched to refraction to the closed folding line 29b. The portion 27b is also rotated around the base point 28b, and the B leaf 24, which is reversed around the base point 28b at the lower end, moves back to the left and stays in the closed position. The leaf A is closed simultaneously with the same mechanism as the leaf 24, and the A leaf 23 rotates around the base point 28a by reversing the reversing fan 27a on the right side of the handle 25.

  The winding state of the sheath portion 3 is fixed by folding the b-sheath 10 on the left side of the middle sheath 8 to the outer surface of the a-sheath 9 and inserting the insertion piece 12 into the kerf 11, as in Example 1. By pushing the closed fan leaf 22 in the direction of the wound sheath portion 3 positioned below, the folded folding of the base folding line 6 is released and the refraction is switched to the intermediate folding line 15, and finally the step folding line 13 is folded. The structure in which the reversal of the storage stage 14 is completed and the storage of the fan leaf 22 is the same as in the first embodiment, but the fan leaf 2 of the first embodiment is closed in three folds so that it is roughly three. Although it becomes a half width, since the structure in which the two fan leaves 22 are superposed in the second embodiment, the width can be reduced only to about a half width.

  In the lower part of the fan leaf 22 of the second embodiment, which has a low reduction rate and remains wide, a storage area 31 is formed by cutting both lateral edges, and the shape of the storage area 31 is substantially the same as the upper part of the inner sheath 8. Thus, the storage area 31 can be stored in the sheath 3 in a wound state.

  Since the present invention can be freely printed, it can also be used as an advertising medium.
