Description

  The present invention relates to an open / close fixing structure for a paper fan.

  The conventional paper fan open / close fixing structure is a structure that incorporates notches in the case of open fixing, and a structure that fixes the open state by overlapping side-turning pieces, and in the case of closed fixing, the essential holes of the fan are bundled and fixed. By doing so, it was a fixed structure capable of maintaining the bundled state even in the closed state.

  In the conventional technology, in order to fix the open state, it is necessary to visually confirm the positional relationship between the cuts, and since it is not fixed in the closed state, there is a possibility that the fan leaves may be separated. . The required hole bundling fixing structure requires an extra structure for bundling the required holes. The present invention solves the problem that the open state is automatically fixed and the closed state is also automatically fixed without considering the above-described problems in the prior art.

The main body has a fan leaf of a leaf and b leaf extending on each fold line of the reversal area that is reversed with the fulcrum as the center, and the overlapping area in the open state of the fan leaf is defined as an open weight area. Side pieces are extended through each side fold line, both of the side pieces overlap in the open area, and the lower part of the a side piece extended by bag-folding the a side fold line on the a leaf is used as a straddling area. A b-side fold line is folded on the b leaf to bulge the lower part of the b-side piece to provide a bulging area, and a b sliding edge is provided in the bulging area, and the b sliding edge is the fulcrum It has a substantially circumferential shape centered on the. The top edge of the outer piece extended by folding the outer fold line on the b leaf is defined as an outer sliding edge, and the outer sliding edge has a substantially circumferential shape with the fulcrum as a center point. The base end of the straddling area is set as a smooth end, and the straddling area is provided so as to slide across the b-sliding edge and the outer sliding edge.

  As the fan leaves are opened, the sliding edge of the straddle area moves from the outer edge to the b sliding edge and slides, so that the fan leaves are not separated but the open state is fixed. As the fan leaves are closed, the sliding edge of the straddling area moves from the sliding edge to the outer edge and slides, so that the closed state is fixed without separating the fan leaves.

  A structure that can automatically fix the open / close state of the paper fan has been realized.

  FIG. 1 is a perspective view of a partially peeled perspective view of a main part in an open state. A perspective line is indicated by a broken line, a peeling line is indicated by a double line, a broken line is indicated by a one-dot chain line, a broken line is indicated by a broken line, and an edge and a cut line are indicated by a single solid line. The folding direction displayed for mountain and valley folds is based on the front direction. The horizontal direction is horizontal, the vertical direction is vertical, and the front-back direction is front and rear. The material forming the present invention is not limited, and plastic may be used, but it is desirable that the paper is appropriately thick, and the hardness of the cardboard is such that it can be easily folded and can withstand use of a fan. If it is harder than a government-made postcard, it can serve its purpose.

  The fan leaf 2 occupying a large area in the main body 1 is composed of two pieces. The fan leaf 2 is collectively referred to as the fan leaf 2; To do. The shape of the fan leaf 2 is not limited as long as it is a shape that can be opened as a fan and used as a fan. The opening shape may be a fan shape, a flower shape, or an animal face shape. The open shape is suitable for the heart shape because the fulcrum 5 is located at the lower end of the center, and the heart shape will be described as a specific shape.

  The a leaf 3 and the b leaf 4 are extended from the inversion area 6 through a fold line, and the inversion area 6 is an area that inverts in the front and back direction with the fulcrum 5 as a center point, and the fulcrum 5 side is at an acute angle. However, it may be a fan shape centered on the fulcrum 5.

  In the first embodiment, the a leaf 3 is positioned on the back side, and the inversion area 6 extending through the open fold line 7 at the lower part of the a leaf 3 is folded to the front, and the fold line from the inversion area 6 is closed. The b leaf 4 is extended through 8, and the open fold line 7 and the closed fold line 8 are provided in a positional relationship of radiation starting from the fulcrum 5.

  The body 1 in the open state has a heart shape with the lower end as a fulcrum 5, and an overlap region that vertically cuts the center from the top and bottom is an open region 9, the open region 9 side is an inside, and the open region 9 In the open area 9, b leaves 4 overlap the front of the a leaves 3, and the overlapping surfaces of the open areas 9 are hidden from each other in the front-rear direction. The side piece is extended by utilizing the hidden area 9. If the side piece extending structure is specifically described, the a side piece 11 is extended through the a side folding line 10 folded from the a leaf 3 to the front, and the b leaf 4 is directed to the back. Since the b-side piece 13 is extended through the b-side folded line 12 which is folded in a bag, the a-leaf 3, the b-side piece 13, the a-side piece 11 and the b-leaf 4 from the back in the open weight region 9. They are folded in order. The open weight region 9 is a region sandwiched between the a-side fold line 10 and the b-side fold line 12 as a dividing line.

  The folding of the a-side piece 13 and the b-side piece 11 alone is not enough to fix the open state of the main body 1, and in order to strengthen the fixing of the open state, the lower part of the b-side piece 13 is placed on the b side. A bulging area 14 is formed by bulging to the side opposite to the fold line 12, and an upper edge of the bulging area 14 is a b sliding edge 15, and the b sliding edge 15 has a substantially circumferential shape with the fulcrum 5 as a center point. The tip region of the b-sliding edge 15 is slightly closer to the fulcrum 5 and the base portion has a partially protruding flange portion 16 in the base region. It is desirable to form.

  In order to firmly fix the open state, the lower region of the a-side piece is defined as a straddle region 17, the base end of the lower edge of the straddle region 17 is defined as a smooth end 18, and the straddle region 17 is the bulge region 14 The sliding end 18 slides on the edge line of the b sliding edge 15 by straddling the line, and the sliding end 18 draws a perfect circle locus with the fulcrum 5 as the center point. The flange part 16 is located at a position slightly protruding from the circumference of the outer periphery of the fan, and the sliding end 18 gets over the flange part 16 just before the fan leaf 2 has been opened. The portion 16 blocks the return of the sliding end 18, so that the open state of the fan leaf 2 is locked and fixed.

  Although the sliding edge 18 can be slid and moved only by the b sliding edge 15, the bulging area 14 for forming the b sliding edge 15 protrudes from the open weight area 9. The outer piece 19 is provided in such a positional relationship that the tip of 14 is not lifted and fixed, and the tip area of the bulging area 14 can be sandwiched and fixed, and the outer piece 19 is folded from the bottom of the b leaf 4 to the back. Further, the bulging area 14 is fixed in a structure sandwiched between bag folds of the outer piece 19. The shape of the outer piece 19 is preferably a fan shape with a substantially circular periphery centered on the fulcrum 5, and the substantially circular periphery is the outer sliding edge 21, and the outer sliding edge 21 is a perfect circular track of the sliding end 18. Although it may be located on the same circumference line, it is desirable that the curve be slightly closer to the fulcrum 5 direction toward the tip of the outer piece 19.

  As shown in FIG. 2, when the main body 1 is in the closed state, the sliding end 18 is in contact with the base (the side closer to the outer folding line 20) region of the outer sliding edge 21. It moves to the sliding edge 15, finally gets over the flange 16 and reaches the base of the sliding edge 15 (the one closer to the b-side piece 13) to be locked. The structural principle of the transition of the contact point is that the bases of the outer sliding edge 21 and the b sliding edge 15 are located on the same circumferential line as the perfect circular track of the sliding end 18, and the tip region is This is because the curve slightly approaches the fulcrum 5. Although all the edge lines of the outer sliding edge 21 and the b sliding edge 15 may overlap on the same circumferential line as the perfect circular orbit of the sliding end 18, the edge line approaches the fulcrum 5 as it approaches. By moving the contact point with the sliding end 18 in a curved line that approaches, the lock fixing ability by the flange 18 is increased.

  FIG. 2 is a perspective view of a partially peeled partially peeled main portion in a closed state. By rotating the a leaf 3 to the right and the b leaf 4 to the left with the fulcrum 5 as the center point, the overlapping area of the fan leaves 2 is widened, and the main body 1 is in a closed state. The overlap with the side piece 11 is released and separated from each other, and the side pieces are separated from each other, so that the sliding end 18 located at the base of the b sliding edge 15 and blocked by the flange 16 is The dam stop is released over the flange 16, the b sliding edge 15 is moved to the outer sliding edge 21 and the place is moved. When the main body 1 is closed, the sliding end 18 is located at the base end of the outer sliding edge 21. The outer folding line 20 that is positioned and extends the outer piece 19 blocks the straddle region 17, thereby preventing the fan leaves 2 from moving further in the closing direction past the closed state.

  The flange 16 may be provided on the outer sliding edge 21, but the flange 16 of the damming structure is located at the central portion of the outer sliding edge 21, so the center of the outer piece 19 is pressed toward the outer folding line 20. In some cases, the outer piece 19 bends due to the pressing force, and if the outer piece 19 is bent, the sliding end 18 cannot get over the flange 16 so that the flange 16 is brought into the b sliding edge 15. It is desirable to provide only.

  The smooth end 18 moves in a perfect circular orbit with the fulcrum 5 as the center point, and the b sliding edge 15 and the outer sliding edge 21 move away from the perfect circular orbit toward the center. The sliding end 18 is prevented from being caught at the tip corner of the bulging area 14, and the flange portion 16 can be reliably exposed, so that the lock fixing ability of the flange portion 16 is improved.

  Since the opening shape of the main body 1 is made into a heart shape, when the main body 1 is closed, a region that protrudes outside the side folding line is generated, and the protrusion region can be opened by being picked and pulled out. Region 22 is assumed.

  FIG. 3 is a developed front view. The folding line is indicated by a one-dot chain line, the folding direction indicated by the valley fold mountain fold is based on the front, all the folding directions in this figure are mountain fold lines, and the structure for folding the mountain fold line is a bag fold folded 180 degrees. To. The region sandwiched between the lower end of the b-side piece 13 and the inversion region 6 is cut out, but this is for ease of illustration and explanation, and it is desirable that the product be left without being cut off when commercialized.

  If the order of assembling by folding the fold line of the main body 1 is described, the b-side piece 13 is first folded back, and then the outer piece 19 is folded back to sandwich the tip region of the bulging area 14. a side piece 11 is folded back, and the folding line 7 at the lower edge of the inversion area 6 is folded in a mountain so that the a leaf 3 is folded back and folded in the open area 9 as shown in FIG. Assembling in the opened state is completed by straddling the straddle region 17 of the side piece 11 tip region over the b sliding edge 15 and the outer sliding edge 21, and the bag folding of the fold line 7 is shifted to the closed fold line 8. As shown in FIG. 2, the main body 1 is in a closed state.

  FIG. 4 is a front perspective view of a partially peeled part of the opened state. Although it becomes Example 2 from FIG. 4, in the said Example 1, it displayed in order of the a leaf 3 and b leaf 4 from the left, in Example 2, it is b leaf 4 and a leaf 3 from the left. Display in the order of. The reason why the left and right are reversed is that it is desired to display the rotation area 6 at the lower part in the opened state of the main body 1 from the front.

  While the open state of Example 1 was a heart-shaped with a pointed bottom, the open state of Example 2 is an open fold line 7 with a flat bottom end, and the fulcrum 5 is an extension of the open fold line 7. Is located. In the open state, the a leaf 3 is slightly longer than the b leaf 4. The structure is almost the same as that of Example 1 except that the two points are different.

  There is a leaf 3 at the forefront (front), and b leaf 4 through an open fold line 7 folded at the lower edge of the inversion region 6 extending through the closed fold line 8 at the lower edge of the a leaf 3. Is extended. The inversion region 6 has a fan shape or a triangular shape sandwiched between two fold lines 7 and a fold line 8 which are two radiations starting from the fulcrum 5, and the fold line 7 and the fold line Although the intersection with 8 is a fulcrum 5, it is desirable that the opening / closing fold line and the fulcrum 5 are slightly separated (2 to 3 mm), and even if the fulcrum 5 is separated, the opening / closing fold line is extended. Since the line is displayed as a thin solid line and the fulcrum 5 is separated, the detailed shape of the inversion area 6 forms a trapezoid very close to a triangle, and the inversion area 6 is trapezoidal. It is a play to escape the influence of the thickness of the wood, and it is easy to create a wooden pattern for punching.

  If the assembly order of the main body 1 is described, the b-side fold line 12 of the b-leaf 4 in a state of being folded back (the front region is located above) is folded and the b-side piece 13 is moved to the front. Folded, folded the outer fold line 20 of the b leaf 4 and folded the outer piece 19 to the front, folded the a side fold line 10 of the a leaf 3 and folded the a side piece 11 to the back, the a side piece 11, the straddling region 17, which is the lower region of the straddling region 17, is straddled between the b-sliding edge 15 and the outer sliding edge 21. The open state of is locked.

  If the region where the b leaf 4 and the a leaf 3 overlap in the opened state of the main body 1 is defined as an open region 9, and the order of folding of the open region 9 is described from the back, the b leaf 4 and the a side piece 11 and b Side pieces 13 and a leaves 3.

  FIG. 5 is a perspective view of a partially peeled partially peeled main portion in a closed state. Both the fan leaves 2 are linked to the reversal area 6 which is reversed with the fulcrum 5 as the center point by moving the folding part of the open fold line 7 which has been folded in the open state of FIG. 4 to the closed fold line 8. 5, and the sliding end 18 passes over the flange 16, contacts the outer sliding edge 21 from the sliding edge 15, and moves to the outer sliding edge 21 to move to the base end (outer side) of the outer sliding edge 21. The closed state is maintained up to the broken line 20).

  The sliding end 18 is fixed in a state of being caught by the flange 16 in the opened state of the main body 1, but since the hook of the flange 16 is removed in the direction of pulling the b-side piece 13, the bulging area 14 may be bent. The contact edge transition from the b sliding edge 15 to the outer sliding edge 21 can be performed without difficulty.

  FIG. 6 is a developed front view. If the order of assembling by folding the fold line of the main body 1 is described, the b-side piece 13 is first folded back, and then the outer piece 19 is folded back to sandwich the tip region of the bulging area 14. a side piece 11 is folded back, and the folding line 7 at the lower edge of the inversion area 6 is folded in a mountain, so that the b leaf 4 is folded back and folded in the open area 9 as shown in FIG. Assembling in the opened state is completed by straddling the straddle region 17 of the side piece 11 tip region over the b sliding edge 15 and the outer sliding edge 21, and the bag folding of the fold line 7 is shifted to the closed fold line 8. As shown in FIG. 5, the main body 1 is in a closed state.

FIG. 7 is a front perspective view of a partially peeled partially peeled state in an open state. Although the opening direction of the main body 1 is not limited, it is desirable to have a structure in which the upper part of the b leaf 4 overlapping the front is rotated and moved to the right.
The third embodiment is a simple type and is characterized in that the assembly can be performed easily. In Example 1 and Example 2, since it has the bulging area 14 and the outer piece 19, the operation | work which straddles the large spanning area 17 at the time of an assembly was required, In Example 3, Since the straddle area 17 is small, it is not necessary to carry out the straddle operation during assembly, so that the assembly can be performed easily.

  It is desirable that both the fan leaves 2 and the inversion area 6 have the same shape as that of the second embodiment. However, the fixing structures for opening and closing the fan leaves 2 are different from each other. For the purpose of clearly explaining the fixing structure, the left and right positional relationship of the fan leaf 2 is reversed from that of the second embodiment in order to show the b-sliding edge 15, the straddle region 17 and the sliding end 18 from the front direction. Illustrated with leaf 3 on the left and b leaf 4 on the right.

  By folding the open folding line 7, the inversion area 6 is folded back and the fan leaves 2 are in an open state, and the area where the fan leaves 2 in the open state overlap is defined as an open weight area 9. The a-side piece 11 and the b-side piece 13 are accommodated in the region of the open weight region 9, and the fan leaf 2 is composed of two pieces of a leaf 3 and b leaf 4, and the a leaf 3 The a-side piece 11 is extended through a bag-folded a-side fold line 10, and the b-side piece 13 is extended from the b-leaf 4 through a b-side fold line 12.

  The a-cut 23 is cut to a substantially central portion of the a-side piece 11 to form a straddle area 17, and the base (the cut back) end of the straddle area 17 is defined as a smooth end 18. The b-cut 24 is cut to substantially the center of the b-side piece 13 to form the b-sliding edge 15, and the flange 16 is provided at a position slightly returned from the base (the notched back) of the b-sliding edge 15.

  The sliding end 18 slides along the edge of the b-sliding edge 15 as both the fan leaves 2 move circumferentially in the direction to open each other, and the sliding end 18 passes over the flange 16 and the base of the b-cut 24. Locked at the end. The locking is performed by the sliding end 18 being blocked by the flange 16 and caught.

  Since the flange portion 16 is a small mountain-shaped upper protruding edge, when a force is applied in the direction in which both of the fan leaves 2 are closed, the sliding end 18 fixed to the base end of the b-cut 24 becomes the flange portion 16. Slid along the edge line of the b-sliding edge 15 and finally slips out from the cut of the b-cut 24 and shifts to the closed state.

  FIG. 8 is a perspective view of a partially peeled partially peeled main portion in a closed state. By folding the closed fold line 8, the state where the overlapping areas of both fan leaves 2 reach the maximum value is set to the closed state, and at least the upper edges of the fan leaves 2 overlap each other. desirable.

  In the closed state of the main body 1, both the b-side piece 13 and the a-side piece 11 are in the most distant positional relationship, but not all of them are separated, and the one-end regions 28 are overlapped without being separated, Since the overlapping region overlaps even in the closed state, it is referred to as a closed region 27.

  Although the b-side fold line 12 and the a-side fold line 10 are bag-folded, it is technically impossible to fold them completely at 180 degrees, so they are not completely folded. The side piece is folded back in an appropriately floating state, and is pressed from the front and rear (front and back) direction in the closed area 27, so both the b-cut 24 and the a-cut 23 are cut. Will open naturally.

  Since both of the cuts can be kept open, when both fan leaves 2 are moved to the open state, both the b cut 24 and the a cut 23 are incorporated into each other, as shown in FIG. Transition to the open fixed state.

  Since the third embodiment is a simple type, the bulging area 14 and the outer piece 19 which are provided in the first and second embodiments are omitted, and therefore the place where the straddling area 17 straddles in the closed state is basically the same. The main body 1 is not fixed in the closed state, and there is little inconvenience even if the main body 1 is not fixed in the closed state. As a place to fix the closed state in the third embodiment, a concave portion 25 is provided in the upper portion of the outer edge of the fan leaf 2, and the edge of the side piece overlapping in the closed state is incorporated into the concave portion 25. The closed state is fixed, and the concave portion 25 may be provided in both the a leaf 3 and the b leaf 4, but either one is sufficient, and the concave portion 25 is provided only in the b leaf 4 for concrete description. The structure to be provided will be described.

  If the fixed structure in the closed state in Example 3 is specifically described, a concave portion 25 is provided by appropriately denting the other (right) side edge upper portion of the b leaf 4 and positioned on the other of the a leaf 3. The concave portion 25 is assembled and fixed to the upper part of the bag-side a-side piece 11, and the edge of the a-side piece 11 may be a straight line, but is positioned on the other side of the a-leaf 3. Then, it is desirable to provide the convex piece 26 by partially projecting the upper part of the a-side piece 11 which is folded in a bag, and the formation of the convex piece 26 significantly increases the probability of successful incorporation of the concave portion 25.

  The closed state of the main body 1 is a state in which the b leaf 4 is exactly overlapped with the front of the a leaf 3, and in the closed state, the bottom side of the main body 1 is located with the closed fold line 8 folded, By rotating the b leaf 4 slightly to the left from the closed state, the protruding piece 26 protrudes to the front, and the lower part of the protruding piece 26 protruding to the front fits into the recessed portion 25 to close the main body 1. The structure is fixed. Only in the third embodiment, the automatic fixing in the closed state is not perfect, but it is a semi-automatic fixing structure since the closing and fixing is performed by just going back slightly from the closed state.

  FIG. 9 is a developed front view. The shape of the fan leaf 2 may be freely designed, but it is desirable that the fan leaf 2 has a substantially fan shape that is elongated vertically (top and bottom), and the fan leaf 2 has two pieces, A leaf 3 and b leaf 4 are displayed as names for distinguishing each of the fan leaves 2.

  Since it is desirable that the b leaf 4 be overlapped on the front in the assembled state, the a leaf 3 is extended under the b leaf 4 through the inversion area 6 in the developed view, and the inversion area 6 is on the left side. It is desirable to have a long and narrow fan shape sandwiched between two radial folding lines with the fulcrum 5 positioned at the center as the center point. The two folding lines sandwiching the inversion region are set as the closed folding line 8 and the top is the opening folding line 7. The closed fold line 8 is preferably a horizontal fold line. The fulcrum 5 is preferably located at a position slightly (2 to 3 mm) away from the inversion area 6, and the fulcrum 5 is at the intersection of the two radial fold lines whose extension lines are indicated by thin solid lines. Since the fulcrum 5 is located outside the inversion area 6, the inversion area 6 forms a trapezoid very close to a triangle.

  The a-side piece 11 is extended to the other side edge of the a-leaf 3 via the a-side fold line 10, and the a-side piece 11 has a substantially right triangle shape that falls within the range of the open area 9 shown in FIG. The corner region of the a-side piece 11 is one end region 28a that forms the closed overlap region 27 shown in FIG. 8, and the a-incision 23 is formed substantially at the center from the lateral outer edge of the a-side piece 11. A straddle area 17 is formed by cutting up to a place, and the rear end where the a cut 23 is cut is defined as a smooth end 18, and a laterally outer end area of the a-side piece 11 (a place away from the one-end area) is partially The convex piece 26 is formed by swelling.

  A b-side piece 13 is extended on one side edge of the b-leaf 4 via a b-side fold line 12, and the b-side piece 13 is in a substantially right triangle shape that falls within the range of the open area 9 shown in FIG. The corner region of the b-side piece 13 is the other one-tip region 28b which forms the closed overlap region 27 shown in FIG. 8, and the b-cut 24 is substantially centered from the lateral outer edge of the b-side piece 13. It is desirable to cut a portion to form the b sliding edge 15, and to cut a sharp corner area by cutting the b notch 24 to form a cutting angle 29. By forming the cutting angle 29, the body 1 can be opened and closed. It is possible to remove acute angle areas that may sometimes get caught.

  b The part where the other side edge upper part of the leaf 4 is partly cut and recessed is defined as a concave part 25, and the shape of the concave part 25 is not limited and may be an appropriate shape. It is desirable to cut out in a substantially V shape.

  If the assembly order of Example 3 is described, the a side folding line 10 is folded in a bag and the a side piece 11 is folded back, the b side folding line 12 is folded in a bag and the b side piece 13 is folded back and closed. The folding line 8 is folded into a bag, the a leaf 3 is folded back, and the b leaf 4 is overlapped on the back to be in a closed state, and the b leaf 4 is slightly shifted to the left in the closed state to return to the recess 25 Is fitted into the base of the convex piece 26 to be in the closed and fixed state shown in FIG.
