[Figure 6] This is a plan view showing the cheering equipment 100 according to Embodiment 1 in a folded state. [Modes for carrying out the invention]

[0009] Embodiment 1. The cheering equipment 100 according to Embodiment 1 will be described below. In the following description, components common to each figure will be denoted by the same reference numeral. Also, each figure is a schematic representation, and the dimensional ratios of each component are not limited to the actual dimensional ratios.

[0010] Figure 1 is a plan view of the unfolded state of the cheering device 100 according to Embodiment 1. The cheering device 100 is used at sporting events, concerts, etc. By switching its usage state, the cheering device 100 can be used as a megaphone to amplify voices, a display device to show cheering messages, etc., and a sound-generating device to produce sound when struck.

[0011] (composition) The cheering equipment 100 is composed of a single, foldable plate-like body 10. The plate-like body 10 is formed from, for example, paper, resin, or a laminate containing paper and resin. The plate-like body 10 has a degree of flexibility that allows it to be folded. When unfolded, the plate-like body 10 has an external shape corresponding to a fan shape.

[0012] In this invention, the external shape corresponding to a fan shape is not limited to a perfect geometric fan shape, but includes a shape in which the width widens from the inner circumference to the outer circumference with respect to a virtual center point C. The plate-like body 10 only needs to have an external shape corresponding to a fan shape, and may have irregularities, notches, insert pieces 60 or flaps 80 described later formed on the outer edge, inner edge, or end in the circumferential direction L.

[0013] In the present invention, the virtual center point C is a virtual point corresponding to the center of the outer shape corresponding to the fan shape of the plate-like body 10. The virtual center point C may not be actually displayed or formed on the plate-like body 10. The virtual center point C is a reference point from which a plurality of bending portions 20 extend radially.

[0014] In the present invention, the radial direction R refers to the direction from the virtual center point C toward the outer peripheral side of the plate-like body 10. Also, in the present invention, the circumferential direction L refers to the direction along the outer peripheral edge of the plate-like body 10 with the virtual center point C as the center. In FIG. 1, the circumferential direction L is indicated by an arrow extending in an arc shape with the virtual center point C as the center.

[0015] In the present invention, one end portion 11 in the circumferential direction L and the other end portion 12 in the circumferential direction L are end portions that approach or overlap each other when the plate-like body 10 is formed into a cylindrical shape. One end portion 11 in the circumferential direction L and the other end portion 12 in the circumferential direction L each extend along the direction from the virtual center point C toward the outer peripheral side of the plate-like body 10. <J

[0016] A plurality of bending portions 20 are formed on the plate-like body 10. The plurality of bending portions 20 extend radially with the virtual center point C as a reference. The plurality of bending portions 20 divide the plate-like body 10 into a plurality of surface portions �0. In the present embodiment, the plurality of surface portions 30 constitute the side surface 51 of a cylindrical body 50, which will be described later, when the cheering tool 100 is used as a megaphone.

[0017] The bending portion 20 is a portion for bending the plate-like body 10. The bending portion 20 is constituted by, for example, a fold line, a ruled line, a thin portion, a perforation or a crease. The bending portion 20 may be formed in advance with respect to the plate-like body 10. The bending portion 20 is formed so as to be bendable into either a mountain fold that protrudes on the front surface side of the plate-like body 10 or a valley fold that protrudes on the back surface side of the plate-like body 10.

[0018] (State of use as a megaphone) FIG. 2 is a perspective view showing an assembled state when the cheering tool 100 according to Embodiment 1 is used as a megaphone. The cheering tool 100 forms a cylindrical body 50 by bending a plate-like body 10 along a plurality of bending portions 20 and rounding it into a cylindrical shape. The user approaches the mouth to the small-diameter side opening 52 of the cylindrical body 50 and makes a sound toward the large-diameter side opening 53. Thereby, the cheering tool 100 functions as a megaphone that amplifies the sound.

[0019] In the present invention, the axial direction of the cylindrical body 50 refers to the direction connecting the small-diameter side opening 52 and the large-diameter side opening 53 of the cylindrical body 50 in the state of being used as a megaphone.

[0020] The plate-like body 10 may form a polygonal cylindrical body 50 when viewed from the axial direction of the cylindrical body 50 in the state of being used as a megaphone. For example, the cylindrical body 50 may be triangular, square, pentagonal, or hexagonal when viewed from the axial direction of the cylindrical body 50. In this case, the plurality of bending portions 20 form the boundaries between the plurality of side surfaces 51 of the cylindrical body 50, and the plurality of surface portions 30 constitute the plurality of side surfaces 51 of the cylindrical body 50.

[0021] In the present embodiment, the plate-like body 10 forms a square cylindrical body 50 when viewed from the axial direction of the cylindrical body 50 in the state of being used as a megaphone. More specifically, the cylindrical body 50 is formed in a frustum of a square pyramid shape. The frustum of a square pyramid shape corresponds to the shape remaining when a square pyramid is cut by a plane parallel to the bottom surface and the solid on the vertex side is removed. The cylindrical body 50 may be a regular square shape or a rectangular shape when viewed from the axial direction of the cylindrical body 50.

[0022] When the cheering tool 100 forms a square cylindrical body 50 when viewed from the axial direction of the cylindrical body 50, the cylindrical body 50 has four side surfaces 51. The plate-like body 10 may have four surface portions 30 corresponding to the four side surfaces 51 of the cylindrical body 50.

[0023] (Retention Structure) Next, the structure for maintaining the assembled state of the cheering equipment 100 as a megaphone will be described. As shown in Figure 1, the plate-shaped body 10 is provided with an insertion piece 60 and a notch 70 into which the insertion piece 60 is inserted. The insertion piece 60 is provided at one end 11 in the circumferential direction L of the plate-shaped body 10. The plate-shaped body 10 has a flap 80 extending from the other end 12 in the circumferential direction L and a flap bend 81 provided at the boundary between the other end 12 and the flap 80.

[0024] The flap 80 is integrally formed as part of the plate-like body 10. The notch 70 is formed along the flap bend 81. When the plate-like body 10 is rolled into a cylindrical shape, the flap 80 is bent along the flap bend 81 and overlaps the inner circumferential surface of the cylindrical body 50. In this way, the flap 80 supports the overlapping portion of the ends of the plate-like body 10 from the inner circumferential surface of the cylindrical body 50.

[0025] In this invention, the flap folding portion 81 is the part for folding the flap 80, and will be described separately from the folding portion 20 that divides the plate-like body 10 into a plurality of surface portions 30. The flap folding portion 81 may be composed of a crease, a score line, a thin portion, a perforation, or a crease.

[0026] With the plate-shaped body 10 rolled into a cylindrical shape, the insertion piece 60 is inserted into the notch 70. This connects one end 11 and the other end 12 of the plate-shaped body 10 in the circumferential direction L. As a result, the plate-shaped body 10 is held in a rolled-up cylindrical shape.

[0027] Multiple insertion pieces 60 may be provided. Also, multiple notches 70 may be provided corresponding to multiple insertion pieces 60. In this embodiment, three insertion pieces 60 are formed and three notches 70 are formed. By inserting the multiple insertion pieces 60 into the multiple notches 70, the shape of the cylindrical body 50 can be stably maintained.

[0028] Figure 3 is an enlarged view showing the retaining structure of the insertion piece 60 of the cheering tool 100 according to Embodiment 1. Figure 3(A) shows the state before the insertion piece 60 is inserted into the notch 70, and Figure 3(B) shows the state after the insertion piece 60 is inserted into the notch 70. The insertion piece 60 has a narrow portion 61 connected to one end 11 in the circumferential direction L of the plate-like body 10, and a wide portion 62 formed on the tip side of the insertion piece 60 beyond the narrow portion 61. Here, the tip side of the insertion piece 60 refers to the side away from one end 11 in the circumferential direction L of the plate-like body 10 in the protruding direction of the insertion piece 60.

[0029] The wider portion 62 is wider than the narrower portion 61 in the width direction intersecting the protruding direction of the insertion piece 60. When the insertion piece 60 is inserted into the notch 70, the flexibility of the plate-like body 10 causes the peripheral edge 71 of the notch 70 to temporarily displace, and the opening width of the notch 70 temporarily increases. As a result, the wider portion 62 is inserted into the notch 70. When the insertion piece 60 is inserted into the notch 70, the narrower portion 61 is located inside the notch 70. In addition, at least a portion of the wider portion 62 is located further back in the insertion direction of the insertion piece 60 than the peripheral edge 71 of the notch 70.

[0030] When the insertion piece 60 attempts to move in a direction that would cause it to withdraw from the notch 70, the wider portion 62 engages with the peripheral edge 71 of the notch 70. This prevents the insertion piece 60 from withdrawing from the notch 70. Figure 3(B) shows the positional relationship in which the narrow portion 61 is located inside the notch 70 and the wider portion 62 engages with the peripheral edge 71 of the notch 70 when the insertion piece 60 is inserted into the notch 70. Also in Figure 3(B), the flap 80 is folded along the flap bending portion 81 and overlaps the inner circumferential surface of the cylindrical body 50.

[0031] (Condition of use as a display device) Figure 4 is a plan view showing an example of the unfolded state when the cheering tool 100 according to Embodiment 1 is used as a display device. The cheering tool 100 is used as a placard, cheering board, or fan when it is not forming a cylindrical body 50 and at least a part of the plate-shaped body 10 is open. The state in which at least a part of the plate-shaped body 10 is open includes, for example, the state in which the plate-shaped body 10 is unfolded, the state in which the plate-shaped body 10 is folded in half, or the state in which the plate-shaped body 10 is partially bent. In this invention, a display device refers to something used to display characters, photographs, designs, cheering messages, team names, player names, advertisements, etc. Display devices include placards, cheering boards, or fans. In this state, at least a part of at least one of the plate surfaces of the plate-shaped body 10 functions as a display surface.

[0032] A display area 40 is provided on the front or back surface of the plate-like body 10. The display area 40 displays cheering messages, photographs, designs, team names, player names, or advertisements. The display area 40 may be formed by printing. The display area 40 may also be an area on which the user can write by hand. The display area 40 may be provided on both the front and back surfaces of the plate-like body 10. The display area 40 may be provided on at least one of the multiple surfaces 30, or it may be provided across multiple surfaces 30.

[0033] Furthermore, when used as a megaphone, the multiple face sections 30 constitute multiple sides 51 of the cylindrical body 50. This allows each side 51 to be used as a display surface even when used as a megaphone. For example, different cheering messages, photos, designs, team names, player names, or advertisements can be displayed on each side 51.

[0034] (Usage as a sound-generating device) Figure 5 shows the folded state of the cheering tool 100 according to Embodiment 1 when used as a sound generating device. Figure 5(A) is a plan view, and Figure 5(B) is a schematic side view seen from the outer periphery. The cheering tool 100 is used as a sound generating device by folding it by alternately performing mountain folds and valley folds along a plurality of folding sections 20. In this invention, a sound generating device refers to something that produces sound when struck. A sound generating device includes a paper fan.

[0035] When used as a sound generating device, mountain folds and valley folds are alternately formed in adjacent bent sections 20. In Figure 5, the bent section 20A that is mountain-folded and the bent section 20B that is valley-folded are shown separately. When one of adjacent bent sections 20 is mountain-folded and the other is valley-folded, the plate-like body 10 becomes a folded state in which the two sections overlap in the thickness direction.

[0036] As a result, the plate-like body 10 is folded into an accordion-like or fan-like shape. The user grasps the inner circumference side of the plate-like body 10, that is, the end closer to the virtual center point C, and strikes the folded plate-like body 10 against their hand or another object. As a result, the cheering device 100 emits sound.

[0037] Thus, in this embodiment, the multiple bent portions 20 form boundaries between the multiple side surfaces 51 of the cylindrical body 50 when used as a megaphone, and are used as mountain folds and valley folds when used as a sound generating device. In other words, the same bent portions 20 are used for both forming the megaphone shape and the sound generating device shape.

[0038] (Dimensional configuration) Figure 6 is a plan view showing the cheering equipment 100 according to Embodiment 1 in a folded state. The cheering equipment 100 may be formed so that, when folded in half, it fits within a rectangular area of ​​A4 size as defined in the international standard ISO 216. A4 size is a paper size with a short side of 210 mm and a long side of 297 mm. Here, the state of being folded in half refers, for example, to a state in which the plate-like body 10 is folded at the center in the circumferential direction L of the outer shape corresponding to a fan shape.

[0039] In this invention, the lateral direction S refers to a linear dimensional direction that intersects the radial direction R when the material is folded in half. In Figure 6, the lateral direction S is indicated by a linear arrow that runs along the width direction of the folded plate-like body 10.

[0040] For example, when folded in half, the length H along the radial direction R of the plate-like body 10 may be 297 mm or less, and the length W along the transverse direction S of the plate-like body 10 may be 210 mm or less. This configuration makes it easy to store the cheering equipment 100 in a clear file that fits A4 size paper. It also makes it easy to mail the cheering equipment 100 using an envelope that fits A4 size paper.

[0041] (effect) As described above, according to the cheering tool 100 of this embodiment, a single plate-like body 10 is divided into multiple surfaces 30 by multiple radially extending bends 20. The plate-like body 10 can be folded along the multiple bends 20 and rolled into a cylindrical shape to form a cylindrical body 50, which can be used as a megaphone. In addition, the plate-like body 10 can be used as a display device when it is not forming a cylindrical body 50 and at least a part of the plate-like body 10 is open. Furthermore, the plate-like body 10 can be used as a sound generating device by folding it along the multiple bends 20 by alternating mountain folds and valley folds. Therefore, a user can cheer in multiple ways, including voice, display, and sound, with a single cheering tool 100. For this reason, the burden of carrying and storing can be reduced compared to preparing multiple types of cheering tools separately for voice cheering, display cheering, and sound cheering. In addition, it is easier to reduce costs compared to purchasing or manufacturing multiple types of cheering tools.

[0042] Furthermore, the multiple bent sections 20 form boundaries between the multiple sides 51 of the cylindrical body 50 when used as a megaphone, and are used as mountain folds and valley folds when used as a sound generating device. Therefore, the same bent section 20 can be used in multiple usage states, simplifying the structure of the cheering device 100.

[0043] Furthermore, when used as a megaphone, the plate-shaped body 10 forms a rectangular cylindrical body 50 when viewed from the axial direction of the cylindrical body 50, and the cylindrical body 50 is formed in the shape of a truncated square pyramid. In this case, multiple sides 51 of the cylindrical body 50 can be used as display surfaces. Therefore, even when used as a megaphone, the displayed content such as cheering messages, photos, designs, and advertisements is easily visible from the surroundings.

[0044] Furthermore, the plate-shaped body 10 is provided with a display section 40 capable of displaying cheering messages, photographs, designs, team names, player names, or advertisements. Therefore, the cheering device 100 can be used as a display device for showing cheering messages, etc.

[0045] Furthermore, the plate-like body 10 is formed from paper, resin, or a laminate containing paper and resin. This makes it easy to construct a lightweight and foldable cheering tool 100. The foldable portion 20 is composed of creases, lines, thin sections, perforations, or fold lines. This makes it easy to fold the plate-like body 10 according to whether it is being used as a megaphone or as a sound-generating device.

[0046] Furthermore, the plate-like body 10 has a flap 80 extending from the other end 12 in the circumferential direction L, and a flap bend portion 81 provided at the boundary between the other end 12 and the flap 80. The notch 70 is formed along the flap bend portion 81, and the flap 80 is bent along the flap bend portion 81 so that it overlaps the inner circumferential surface of the cylindrical body 50 when the plate-like body 10 is rolled into a cylindrical shape. As a result, the flap 80 can support the overlapping portion of the ends of the plate-like body 10 from the inner circumferential surface. Therefore, the shape of the cylindrical body 50 can be stably maintained while it is being used as a megaphone.

[0047] Furthermore, the insertion piece 60 has a narrow portion 61 connected to one end 11 in the circumferential direction L of the plate-like body 10, and a wide portion 62 formed on the tip side of the insertion piece 60 that is wider than the narrow portion 61. When the insertion piece 60 is inserted into the notch 70, the flexibility of the plate-like body 10 temporarily increases the opening width of the notch 70. This makes it easier to insert the wide portion 62 into the notch 70. Also, when the insertion piece 60 is inserted into the notch 70, the narrow portion 61 is located inside the notch 70, and the wide portion 62 locks onto the peripheral edge 71 of the notch 70 when the insertion piece 60 tries to move in the direction of coming out of the notch 70. Therefore, it is possible to prevent the insertion piece 60 from coming out of the notch 70 while using it as a megaphone, and to prevent the shape of the cylindrical body 50 from being unintentionally released.

[0048] Furthermore, when the plate-shaped body 10 is folded in half at the center in the circumferential direction L of its outer shape, which corresponds to a fan shape, the length H along the radial direction R is 297 mm or less, and the length W along the transverse direction S is 210 mm or less. Therefore, the cheering equipment 100, when folded in half, can be contained within the rectangular area of ​​A4 size as defined in the international standard ISO 216. Consequently, the cheering equipment 100 is easy to store in a clear file that accommodates A4 size paper and easy to mail using an envelope or the like that accommodates A4 size.

[0049] (modified version) In the above embodiment, an example was described in which the plate-like body 10 is formed from paper, resin, or a laminate containing paper and resin. However, the material of the plate-like body 10 can be any material that can form a single, foldable plate-like body 10.

[0050] In the above embodiment, an example was described in which the insertion piece 60 has a narrow portion 61 and a wide portion 62. However, the shape, dimensions, and formation position of the narrow portion 61 and the wide portion 62 can be changed within a range that prevents the insertion piece 60 from coming out of the notch 70.

[0051] In the above embodiment, an example was described in which three insertion pieces 60 are formed. However, the number of insertion pieces 60 may be one, two, or four or more. The number of notches 70 can also be changed according to the number of insertion pieces 60.

[0052] In the above embodiment, an example was described in which the notch 70 is formed along the flap bend 81. However, the notch 70 may be formed on the flap 80, or it may be formed directly on the other end 12 side in the circumferential direction L of the plate-like body 10. Furthermore, the flap 80 may be omitted.

[0053] In the above embodiment, an example was described in which a cheering message, photograph, design, team name, player name, or advertisement is displayed on the display unit 40. However, the content displayed on the display unit 40 is not limited to these. Numbers, symbols, colors, patterns, or combinations thereof may also be displayed on the display unit 40.

[0054] In the above embodiment, an example was described in which the display unit 40 is pre-provided on the plate-like body 10. However, the display unit 40 may be formed by the user during use. For example, the plate-like body 10 may be provided with a blank area that can be handwritten on.

[0055] In the above embodiment, an example was described in which the cheering equipment 100, when folded in half, fits within an A4-sized rectangular area as defined in the international standard ISO 216. However, the dimensions of the cheering equipment 100 can be changed depending on the purpose of use, the age of the user, the size of the venue, or the method of mailing. The configuration that fits within an A4-sized rectangular area is just one example to improve portability, storage, and mailability.

[0056] The above embodiments and modifications are examples that embody the present invention and do not limit the technical scope of the present invention. The configurations shown in the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. Furthermore, the configurations shown in the above embodiments and modifications can be modified, omitted, added, or replaced as appropriate, as long as they do not depart from the spirit of the present invention.
