  The present invention relates to a folding and fixing structure for a paper fan.

  A conventional paper fan folding and fixing structure is provided with a vertically long substantially fan-shaped central chamber in the center of a substantially fan-shaped fan leaf, and a groove is cut in the lower portion of the center chamber, and a separate handle is required in the groove. Insert the pieces and connect them, fold the side chambers that are extended to both sides of the central chamber via the fold line in the same direction (front), cut the tatami slot into the other side of the side chamber, and set the outer angle of the one side chamber to It was the thing of the structure which inserts in a tatami insertion groove | channel, and fixes the folding state of a fan leaf in the state which this side chamber overlapped. In the paper prickly pear, there was a prickly hole (perforated prickly) with a circular finger hole at the bottom of the circle.

JP-A-11-318531

  The conventional technique requires a work of inserting / removing a main piece into / from a required groove, such as attaching a handle to a fan leaf at the time of use and removing a handle at the time of folding. There is a problem that it cannot be folded with a circular perforated prickly, and the folded state cannot be fixed even if it is forcibly folded. In the present invention, the problem as described above is solved.

  A vertical fan-shaped middle fan-shaped middle chamber is provided at the center of the fan leaf, a finger hole is provided at the lower center of the middle chamber, and the outer chamber extends from each side of each side of the middle chamber via a fold line. One outer chamber is extended from the middle chamber via one fold line, and the other outer chamber is extended from the middle chamber via the other fold line. By folding the outer chambers on both sides and stacking them on the middle chamber, the fan leaves are folded, and in order to fix the folded state, incisions from the outer edge are made in each outer chamber, and the notches are separated from each other. The folded state is fixed by assembling together in the folded state. Another outer chamber is folded from above the outer chamber in which the kerf is inserted, and a region within the range of the kerf is provided as an insertion edge at the outer edge of the outer chamber folded later.

  By providing a finger hole in the lower part of the middle chamber, you can hang your finger in the finger hole, making it easier to hold and fan, and by providing a fold line, the outer chamber is folded and folded into the middle chamber Therefore, it can be folded and carried in a compact state. Since the middle chamber is vertically long and has a substantially fan shape, the lower width of the middle chamber is appropriately narrow, and the fingers protruding from the bottom of the suitably narrowed middle chamber are in the adjacent outer chamber. Since the lower part is also sandwiched at the same time, the folding line can be prevented from being refracted when the fan is used. By incorporating cuts from the outer edge, the state where one and the other outer chamber overlap each other can be fixed. The state where the outer chambers overlap can be fixed by inserting the insertion edge of the outer chamber overlapping the front into the groove of the outer chamber overlapping the back.

It is a front view of an open state. Example 1 It is a principal part perspective front perspective view of a folding fixation state. It is a front view of an open state. (Example 2) It is a principal part perspective front perspective view of a folding fixation state. It is a front view of an open state. (Example 3) It is a principal part perspective front perspective view of a folding fixation state.

  A folding fan fixing structure that can be folded and fixed by placing a finger on the fan leaf itself has been realized.

  FIG. 1 is a front view of the opened state. A broken line is indicated by a one-dot chain line, an edge and a cut line are indicated by a single solid line, and a lead (instruction) line is indicated by a thin curve. The folding direction displayed for mountain and valley folds is based on the front direction in the open state. The horizontal direction is horizontal, the vertical direction is vertical, and the front-back direction is front and rear. The code is displayed as a number. When there are a plurality of the same code, an auxiliary code with one as a and the other as b is displayed after the code, and when the auxiliary code is not displayed, a generic name of one and the other ( The positional relationship between one and the other is not limited, but the left in the open state diagram is one and the right is the other. The material forming the present invention is not limited, and may be plastic, but it is desirable that the cardboard is appropriately thick, and the hardness of the cardboard is easily folded and bent appropriately for use as a fan. It should be hard enough to withstand, and specifically, if it is more than twice as hard as a government-made postcard, it can serve its purpose.

  Example 1 is a cut fixed type. The whole main body 1 is formed of a fan leaf 2, and the shape of the fan leaf 2 is not limited, but is preferably substantially fan-shaped with the lower edge appropriately narrowed, and the lower edge is appropriately rounded. Since it becomes easy to have a shape, it is desirable.

  The middle of the fan leaf 2 is a middle chamber 3, which has a vertically long substantially fan shape penetrating into the top and bottom, and has a finger hole 4 formed in the middle of the lower part of the middle chamber 3. The shape of the hole 4 is not limited, but is preferably circular.

  The left and right sides of the middle chamber 3 are fold lines 5, and the outer chamber 6 is extended through each of the fold lines 5. If the positional relationship of the extension is specifically described, one outer chamber 6a extends from the left side of the middle chamber 3 via one fold line 5a, and the other chamber 6 extends from the right side of the middle chamber 3 to the other side. The other outer chamber 6b is extended through the fold line 5b.

  A cut edge region in contact with the outer chamber 6 is defined as an outer edge 7, and a cut 8 is made from the approximate center of the outer edge 7. The notch 8 is shown as two parallel lines, but it is for the purpose of clearly indicating that they are separated, and is actually a single notch. Although the length of the notch 8 is late in FIG. 2, it is desirable to set the length to the center line of the middle chamber 3.

  The outer edge 7 has a region above the notch 8 as an upper outer edge 9 and a region below the notch 8 as a lower outer edge 10. Although the corners of the notches 8 may be rounded, it is desirable to round them appropriately. The upper outer edge 9 and the lower outer edge 10 may be located on the same line, but it is desirable to form a step by projecting either one between the upper and lower sides. It is desirable to reverse. As another method for forming the step between the upper and lower sides, although not shown, a fold line may be formed in a direction substantially perpendicular to the notch 8, and the step may be generated by refraction of the substantially right-angle fold line.

  If the positional relationship of the notch 8 is described concretely, one notch 8a is put in the approximate center of one outer edge 7a on the left side, and the other notch 8b is put in the approximate center of the other outer edge 7b on the right side. Put in. Although it is desirable to project either the upper outer edge 9 or the lower outer edge 10 adjacent in the vertical direction, it is not limited which one is projected, but if specifically described, one outer edge 7a has one lower outer edge 10a. It is desirable that the other outer edge 7b protrudes the other upper outer edge 9b.

  It is preferable that the main body 1 is folded by folding both of the fold lines 5. Since the middle chamber 3 has a vertically long and substantially fan shape with a wide upper portion, the upper portion of the outer chamber 6 that is overlapped with the middle chamber 3 and folded is appropriately widened. The groove 11 for inserting and fixing the partial region of the outer edge 7 on the opposite bank that overlaps when the main body 1 is folded is preferably an upper region of the outer chamber 6.

  Since the other upper outer edge 9b protrudes, it is natural that one upper outer edge 9a is folded to the back in the process of folding the main body 1. Therefore, the upper outer edge 9b is overlapped on the upper side of one outer chamber 6a that overlaps the back surface. A cut groove 11 is inserted, and a part of the upper region of the other outer edge 7 b inserted into the cut groove 11 is defined as an insertion edge 12.

  FIG. 2 is a transparent front perspective view of a main part in a folded and fixed state. The see-through location is indicated by a broken line, and up to two pieces of see-through are displayed. In the case of two-piece see-through, the distance between the broken lines is widened to form a thin line so that it can be distinguished from a single see-through.

  Both fold lines 5 are simultaneously folded at the same angle so that both outer chambers 6 are folded back to the front. Since the other upper outer edge 9b protrudes from the other upper outer edge 9a, the possibility that the other upper outer edge 9b overlaps the front face is reliably increased when the outer chamber 6 is folded. Contrary to the upper outer edge 9, at the lower outer edge 10, one lower outer edge 10a protrudes from the other lower outer edge 10b. Therefore, when the outer chamber 6 is folded, the other lower outer edge 10b may overlap the back surface. Will definitely be higher.

  As described above, since the left and right protrusions of the upper outer edge 9 and the lower outer edge 10 are upside down and the opposite outer edges protrude, the one notch 8a and the other notch 8b are in a state of being incorporated into each other. The front folded state of the outer chambers 6 is fixed, and the folded state of the main body 1 is fixed.

  The length of the notch 8 is not limited, but it is desirable that the end portions where the notches 8 are assembled are located on the center line of the inner chamber 3, and the center line of the inner chamber 3 is vertical. It is desirable that the cut 8 incorporated on the horizontal line substantially perpendicular to the vertical center line of the middle chamber 3 is located.

  Although the fixing of the folded state of the main body 1 is not a problem just by inserting the notches 8 into each other, the tip of the other upper outer edge 9b is slightly lifted, and the insertion edge 12, which is the tip region of the other upper outer edge 9b, is cut. It is desirable to provide it as a place where the other upper outer edge 9b can be prevented from being lifted by being inserted into the groove 11.

  FIG. 3 is a front view of the opened state. In Example 1, since it is necessary to provide the notches 8 from both the left and right ends, it is difficult to make the outer edge 7 a smooth curve. The structure cannot be symmetrical. In the second embodiment, a folding and fixing structure of the symmetrical fan leaf 22 that is a desirable shape will be described.

  Example 2 is an outer chamber kerf type. Since the fan leaf of the overall shape has changed from one embodiment to another, the sign attached to the back is changed. In Embodiment 2, the fan leaf 22 is used, and the entire portion including the portion attached to the fan leaf 22 is included. Is a main body 21.

  The fan leaf 22 may have a freely designed shape, but it is desirable that the fan leaf 22 has a substantially symmetrical fan shape. It is desirable that the center of the fan leaf 22 be a middle fan chamber 3 having a vertically wide fan shape having substantially the same shape as that of the first embodiment. A circular finger hole 4 is provided at a substantially lower center of the middle chamber 3. Japanese Patent Application Laid-Open No. 11-318531 of Patent Document 1 specified in the prior art does not have a circular finger hole 4 and has a structure in which a finger cannot be caught.

  One outer chamber 6a extends on one side of the middle chamber 3 via one fold line 5a. The other outer chamber 6b is extended on the other side of the middle chamber 3 via the other fold line 5b. The edge of the outer chamber 6 that connects the top and bottom ends of the fold line 5 is defined as an outer edge 7, and the outer edge 7 preferably has a substantially square shape with a rounded corner with a substantially upper portion protruding. The rounded corner region is defined as an insertion edge 12, and a kerf 11 is formed in a substantially upper portion of the outer chamber 6 with a substantially straight line that can be easily inserted into the insertion edge 12.

  FIG. 4 is a perspective front perspective view of a main part in a folded and fixed state. By folding the fold line 5 on both the left and right sides, both the outer chambers 6 are folded back to the front, and the folding order of the outer chambers 6 is not limited. It will be illustrated in a stacked state with 6b in front.

  The folded state of the main body 21 is fixed by inserting the insertion edge 12b of the other outer chamber 6b overlapped with the front face into the groove 11a of the one outer chamber 6a overlapped with the rear face.

  FIG. 5 is a front view of the opened state. Example 3 is a middle chamber kerf type. In the third embodiment, a substantially circular fan leaf 32 is formed, and the lower portion of the fan leaf 32 has a shape that is substantially as wide as the upper portion. The fan leaf 2 of Example 1 and the fan leaf 22 of Example 2 were clearly wider at the top than the bottom, but the lower portion of the fan leaf 32 of Example 3 was as wide as the top. By doing so, the bay peak at the outer edge 7 moves to the lower part, and it becomes necessary to change the folding fixing structure.

  The middle chamber 3 is provided in the center of a circular fan leaf 32 including a substantially circular shape and is vertically long and has a vertically long fan shape, and the outer chamber 6 is extended to both sides of the middle chamber 3 via a fold line 5. . It is desirable to make the lower region of the outer edge 7 of the circumferential outer chamber 6 appropriately protrude when folded by appropriately narrowing the lower portion of the middle chamber 3.

  A finger hole 4 is provided in the lower part of the middle chamber 3, and the finger hole 4 is shown in a circular shape. However, the left and right sides of the finger hole 4 extend laterally and reach the fold line 5. Anyway.

  It is desirable to provide a pair of symmetrical grooves 11 at a location slightly above the center of the middle chamber 3, and it is desirable that the grooves 11 provided in pairs are substantially C-shaped.

  Since the fan leaf 32 is circular, the outer chamber 6 extending outward through the fold line 5 has a vertically long semicircular shape. The edge of the outer chamber 6 connecting the upper and lower ends of the fold line 5 is an outer edge 7, and a part of the upper portion of the outer edge 7 becomes an insertion edge 12 to be inserted into a distant groove 11 when folded, and the lower part of the outer edge 7 Most of the area is a protruding area 13 that protrudes from the middle chamber 3 when folded.

  FIG. 6 is a perspective front perspective view of a main part in a folded and fixed state. The outer chamber 6 turned back via the fold line 5 has a vertically long semicircular shape, and the bay peak at the outer edge 7 moves up and down depending on the inclination angle of the fold line 5. If the fold line 5 is vertical, the bay peak at the outer edge 7 is located directly beside the center, and the ridge peak at the outer edge 7 moves downward as the top of the fold line 5 moves outward and tilts. Moving. In the case where the shape in which the top portion of the fold line 5 is appropriately inclined outward and the lower portion of the middle chamber 3 is appropriately narrow has the lower portion of the open fan 32 sandwiched between fingers, 3 and the outer chamber 6 can be held together so that the lower portion of the middle chamber 3 is appropriately narrowed.

  In Example 3, since the lower part of the outer chamber 6 protrudes from the middle chamber 3 when folded, it is somewhat difficult to fold both the folding lines 5 in the same direction. The folding direction of the fold line 5 is not limited and can be freely changed by the user. However, in order to specifically explain, one fold line 5a is folded and one outer chamber 6a is opened in front. The other fold line 5b is folded in a mountain, and the other outer chamber 6b is folded back to be folded.

  The approximate center of one outer edge 7a of one outer chamber 6a folded back to the front is an intersection with the other fold line 5b, and an area adjacent to the intersection is defined as one insertion edge 12a. By inserting the insertion edge 12a into the other cut groove 11b, the folded state of one outer chamber 6a is fixed, and it protrudes from the other fold line 5b to the other in the region adjacent to the intersection. A region that is present is defined as one protrusion region 13a.

  The approximate center of the other outer edge 7b of the other outer chamber 6b folded back is the intersection with the one fold line 5a, and the upper adjacent region of the intersection is the other insertion edge 12b. The folded-back state of the other outer chamber 6b is fixed by inserting the insertion edge 12b into one of the cut grooves 11a, and it protrudes from one fold line 5a to one in the region adjacent to the intersection. Let the area | region which exists be the other protrusion area | region 13b.

  Since the protrusion area 13 can also be used as a finger hooking portion, the protrusion area 13 is hooked with, for example, the index finger of the right hand, and the upper adjacent area is lightly pressed with the thumb, and the upper surface of the outer chamber 6 is slightly bent. Then insert the insertion edge 12 into the kerf 11. The insertion edge 12 can be easily pulled out by hooking and pulling, for example, an index finger from the state of the insertion edge 12 in the inserted state to the protrusion area 13.

  The present invention can also be used as an advertising medium.
