Mode for Carrying out the Invention

A foldable pompon according to a first embodiment of the invention is described with reference to the accompanying drawings. The foldable pompon 1 includes two semicircular portions 1a, and has a size which is holdable with one hand. As illustrated in Fig. 1, the semicircular portion 1a includes a handle 10 having a grip part 12 provided at an upper portion of a semicircular fixed part 11, and a number of thin pieces 21, 22, 23, ... attached to the back side of the handle 10 via coupling pieces 30, 31, 32, ..., providing a fan-like shape as a whole as viewed from the front. While the fixed part 11 and the grip part 12 are made of paper, other materials and shapes may be adoptable.
Fig. 2 illustrates some of a number of thin pieces. The thin pieces 21, 22, 23, 24 are made of a PET film, are strips of a rectangular shape which is approximately 5 cm in width and 10 cm in length, and both sides of one end of each thin piece are cut off to be a sharp- angled portion 21a, 22a, 23a, 24a. Although the size and the material, or the shape and the quantity of the thin pieces can be arbitrarily determined, the material is preferably a film of a synthetic resin with a certain elasticity.
In addition, coupling pieces 30, 31, 32, 33, 34 made of a semicircular pet film slightly smaller than the fixed portion 11 are prepared. Of the coupling pieces, the coupling piece 30 should be adhered onto a back side 11b of the fixed part 11.
How to make the semicircular portion 1a of the embodiment is described with reference to Fig. 2.
Two of the strip thin pieces 21 are fixed to the coupling piece 31, which is in turn fixed onto the coupling piece 30.
At this time, the fixing is carried out in such a way that the distal ends of the sharp-angled portions 21a of the two thin pieces 21 abut on each other at a midpoint C of the back side 11b of the fixed portion 11. Accordingly, the two thin pieces 21 are fixed radially at an angle of about 60° about the midpoint C.
As illustrated in Figs. 2 and 5, the coupling piece 31 has adhesive parts 31a provided between the thin piece 21 and thin pieces 21 and along both sides of the sharp-angled portions 21a of the thin pieces 21, and is fixed onto the coupling piece 30 by adhering those adhesive parts thereto.
Then, three thin pieces 22 are fixed to the coupling piece 32 at equal intervals so that, like the thin pieces 21, the thin pieces 22 are radially positioned about the midpoint C, and the coupling piece 32 is fixed by stacking it on top of the coupling piece 31.
At this time, the three thin pieces 22 are respectively positioned at a middle of the thin pieces 21, 21 and both sides thereof, and are fixed by stacking them on top of the pieces 21 one another in such a way that the individual thin pieces 22 are visible between the thin pieces 21, 21, as illustrated in Fig. 1.
Further, as illustrated in Figs. 2 and 5, the coupling piece 32 has adhesive parts 32a, 32a provided along the thin piece 22 and thin pieces 22, and is fixed onto the coupling piece 31 by using those adhesive parts. The adhesive parts 32a, 32a are positioned at the portions that correspond to the lengthwise center lines of the thin pieces 21, 21.
Likewise, the coupling pieces 33, 34 to be described below are respectively fixed to the coupling pieces 32, 33 using adhesive parts 33a, 34a respectively provided at the coupling pieces 33, 34.
Then, the coupling piece 33 having two thin pieces 23 adhered thereon is fixed on top of the coupling piece 32. At this time, as mentioned above, the two thin pieces 23 are placed on top of the coupling piece 32 in such a way that the individual thin pieces 23 are visible between the three thin pieces 22.
Furthermore, the coupling piece 34 having three thin pieces 24 adhered thereon is placed on top of the coupling piece 33 in such a way that the thin pieces 24 are visible between the two thin pieces 23.
In this way, two thin pieces and three thin pieces are alternately stacked with the overlapping portions being reduced, so that the overlying thin pieces are visible between the underlying thin pieces. As a result, the thin pieces 21, 22, 23, 24 are fixed to the handle 10 to provide the semicircular portion 1a having a fan-like shape as viewed from the front (see Fig. 1).
Two semicircular portions 1a are prepared and are coupled to each other in a relatively rotatable manner with a string 13 serving as coupling means at the lower end of the fixed part 11 (see Fig. 3). Further, the topmost thin pieces 24 of the two semicircular portions 1a are coupled together with their adhesive parts.
The action of the first embodiment configured in the above-described manner is described.
To use the embodiment as a pompon, the handles 10, 10 are rotated 180°, with the grip parts 12, 12 gripped, so as to align the top surfaces of the handles 10, 10 into a spherical shape, and are held (see Fig. 4).
At this time, the overlaid coupling pieces 31, 32, 33, 34 are connected consecutively with their adhesive parts 31a, 32a, 33a, 34a, with the other portions unconnected. Therefore, when the coupling pieces are pulled with the rotation of the handles 10, 10, because of the coupling piece 30 being fixed to the fixing portion 11, the other coupling pieces 31, 32, ... are pulled in the direction of an arrow in Fig. 5 by the adhesive parts 32a, 33a, ....
As a result, the intervals of the coupling pieces 31, 32, ... become gradually wider; however, since the adhesive parts of the coupling pieces are positioned at the portions that correspond to the lengthwise center lines of the thin pieces which are fixed to the underlying coupling piece as mentioned above, the adhesive part 32a pulls the thin piece 21, the adhesive part 33a pulls the thin piece 22, and the adhesive part 34a pulls the thin piece 23, so that the thin pieces 21, 22, ... are efficiently widened in the arrow direction.
Although only four layers of thin pieces 21 to 24 are illustrated in connection with this embodiment, the invention is not limited thereto. In general, ten or more layers of thin pieces are stacked on a single semicircular portion 1a, so that in case of a pompon as illustrated in Fig. 4, a number of thin pieces make a spherical shape as a whole, which demonstrates gorgeous effect.
In addition, in case of using the embodiment as a fan, surfaces 11a, 11a of the fixed parts 11, 11 should only be held with fingers since closing the handles 10, 10 of the foldable pompon 1, to the contrary to the above case, causes the thin pieces 21, 22, ... to be laid one on another to form a flat plate. Accordingly, the thin pieces 21, 22, ... sway to feed wind, so that the embodiment serves as a fan. This is effective in a hot season, at the time of watching sports events.
While the thin piece 21 and the coupling piece 31 are prepared separately and are laid on each other in the above-described embodiment, a thin piece 51 and a coupling piece 61 are structured integrally in another example illustrated in Fig. 6. Specifically, in Fig. 6A, two thin pieces 51 are formed at an angle of substantially 60° at symmetrical positions from the center of the upper arcuate portion of the coupling piece 61 having the same shape as the coupling piece 31. This thin piece 51 has the same shape as the thin piece 21 having the distal end of its sharp-angled portion 21a cut away in an arcuate shape, and is attached to the upper arcuate portion of the coupling piece 61.
Reference numeral 61a denotes an adhesive part provided along a line 51b which is an extension of a distal-end shape 51a of the thin piece 51.
Fig. 6B illustrates a case where there are three thin pieces 52 which are attached to a coupling piece 62 at equal intervals at angles of substantially 60°. Reference numeral 62a denotes an adhesive part provided along a line 52b which is an extension of a distal-end shape 52a of a thin piece 52. The provision of the adhesive parts 61a, 62a in such a way brings about an action and effects of thin pieces 51, 52 and coupling pieces 61, 62 similar to the thin pieces and the coupling pieces of the first embodiment.
A number of units each including the thin piece 51 integrated with the coupling piece 61 or the thin piece 52 integrated with the coupling piece 62 are stacked one on another to provide the semicircular portion 1a.
This embodiment demonstrates an effect of easy fabrication in addition to the effect brought about by the above embodiment.
Although not shown, an advertisement or photo, a logo and the like of a sponsor may be illustrated on the surface of the handle 10. Further, in case of using the pompon in a one-man show or the like of a star such as a singer, a photo of the star may also be adhered. Both modifications are effective in warming up the atmospheres of the scenes. In addition, in cheering in a sports event such as soccer or baseball, if the logo of a supporting team or the photo of a player in the team or the like is illustrated on the surface, it becomes a keepsake even after it is used.
Fig. 7 illustrates a second embodiment of the invention.
This embodiment has an ornament 40 sandwiched and fixed between the coupling pieces 31, 32, ... of the semicircular portion 1a structured in the above-described manner. According to this embodiment, with the semicircular portions 1a closed, only a part of the upper portion of the ornament 40 is visible, whereas with the semicircular portions 1a open to be a pompon, the ornament 40 is visible, providing a good element of surprise and fun. This ornament may be varied by changing its shape with different ways of cutting for characters, a Christmas tree and so forth.
As described above, each embodiment has the following effects.

(1) The embodiment is convenient to be carried around to a concert hall, a place of a sports event, etc., and is thus useful as a cheering goods. Further, when a concert hall or the like is hot, the embodiment may be folded to be used as a fan.
