[Embodiment of the invention]

 The basic embodiment of the megaphone of the present invention will be described with reference to FIGS. 1 to 3, and the megaphone 1A is mainly composed of a tubular body 1, a grip body 2 and a swing rod 3.

First, the tubular body 1 will be described. The tubular body 1 is formed into a thin tubular shape by integrally molding synthetic resin. A tip opening 11 is formed on the tip surface of the tubular body 1. The tip opening 11 is formed with a diameter slightly smaller than the outer diameter of the tubular body 1. However, the shape of the opening is not limited to the circular shape.

A rear end wall 14 that closes the rear end surface of the tubular body 1 is formed at the rear end of the tubular body 1. A circular rear end opening 16 having a smaller diameter than the front end opening 11 is formed in the center of the rear end wall 14.

Further, on the rear end wall 14, a mounting cylinder (mounting portion) 6 in which the diameter and the inner diameter of the rear end opening 16 are formed to be substantially the same is formed perpendicular to the rear end wall 14. At the end of the mounting cylinder 6 opposite to the rear end wall 14, there is formed a locking portion 62 projecting in the outer peripheral direction beyond the outer diameter of the mounting cylinder 6. In the present embodiment, as an optimum example, the shape of the locking portion 62 is a continuous protruding edge (flange) shape protruding from the outer periphery of the mounting cylinder 6, but it is not a continuous protruding edge shape but is intermittent or partial. A shape provided with a protrusion may be used. Further, the cylindrical body 1 and the mounting cylinder 6 may be integrally molded by molding synthetic resin, or may be formed as separate bodies and bonded by a method such as adhesion or screwing.

Next, the grip body 2 will be described. A grip body 2 is attached to the rear end side of the tubular body 1, that is, the attachment tube 6 portion. The grip body 2 is composed of an upper body 21 and a lower body 22 which are divided into two parts having substantially the same shape. When these are combined, an opening is formed on both end faces, and the opening is formed inside. A space portion that communicates is formed. In addition, the outer diameter of the grip body 2 is formed to resemble the grip of a baseball bat in this embodiment. That is, the outer diameter gradually decreases from the front end side in the longitudinal direction toward the rear end side to form a small diameter portion (grip portion in the case of a bat), and a portion with a large outer diameter again in the vicinity of the rear end (also in the bat). If the grip end) is formed.

Next, the upper body 21 will be described. The upper body 21 is formed by integral molding of synthetic resin, and a semicircular mounting plate 24a (24b in the lower body 22 described later) is formed on the tip end surface thereof at right angles to the longitudinal direction of the upper body 21. There is. The mounting plate 24a is formed with a semicircular cutout 23a (23b in the lower body 22 described later) having a diameter substantially equal to the outer diameter of the mounting cylinder 6 at the center of the diameter. At a position slightly separated from the mounting plate 24a toward the rear end, like the mounting plate 24a, a semicircular cutout 27a having a diameter substantially equal to the outer diameter of the mounting cylinder 6 is formed in the central portion of the diameter. A rib 25a (27b in the lower body 22 described later) is formed (25b in the lower body 22 described later).

The mounting plate 24a and the rib 25a are arranged so that the center lines of the circles of the notches 23a and 27a are concentric and the disk surfaces of the mounting plate 24a and the rib 25a are parallel to each other. The distance between the rear end wall 14 and the locking portion 62 is substantially the same as the length of the same diameter portion of the mounting cylinder 6.

On the rear end surface of the upper body 21, a semicircular cutout 7 a (lower body 22 that forms a mouthpiece 7 as a megaphone when the upper body 21 and the lower body 22 are combined to form the grip body 2). 7b) is formed.

Between the mounting plate 24a of the upper body 21 and the rib 25a, mounting bosses 81a, 82a formed with female threads for fixing the joint between the upper body 21 and the lower body 22 are formed. The end surfaces of the mounting bosses 81a and 82a are formed to have a height that makes contact with mounting bosses 81b and 82b of the lower body 22, which will be described later, when the upper body 21 and the lower body 22 are joined. In this case, the optimum mounting boss height is the same as the joint surface 29a where the upper body 21 and the lower body 22 are joined, or the joint surface is left in order to leave a tightening margin by the fixing screw 95. It is formed slightly lower than 29a.

Further, mounting bosses 83a, 84a are formed on the rear end side of the rib 25a of the upper body 21 and along the longitudinal direction from the rib 25a to the rear end portion. Female screws are formed on the mounting bosses 83a and 84a similarly to the mounting bosses 81a and 82a. The end surfaces of the mounting bosses 83a and 84a are formed to be slightly higher than the joint surface 29a where the upper body 21 and the lower body 22 are joined. Further, each of the mounting bosses 83a, 84a is formed with four radial support ribs 88 having a support surface 86 at a position slightly lower than the end surface. The supporting ribs 88 having the mounting bosses 83a, 84a and the supporting surface 86 are used for engaging the mounting bosses 83b, 84b of the lower body 22, which will be described later, and for fixing the swing rod 3.

Next, the lower body 22 will be described. The shape of the lower body 22 is substantially the same as that of the upper body 21, and is also formed by integral molding of synthetic resin. However, the shape of the mounting bosses 83b and 84b is different from that of the upper body 21. The mounting bosses 83b and 84b are formed with a hole at the center for allowing the threaded portion of the fixing screw 95 to pass therethrough. The height of the tip surfaces of the mounting bosses 83b, 84b is formed lower than that of the joint surface 29b. Further, a spot facing portion 94 is formed at the tip portion. As will be described later, the counterbore portion 94 is configured so that the tips of the mounting bosses 83a and 84a, which protrude through the mounting holes 90 and 91 of the swing rod 3, are fitted therein.

Next, the swing rod 3 will be described. The megaphone of the present invention is provided with a rocking rod 3 which can rock inside the tubular body 1 of the megaphone. The oscillating rod 3 is formed of a synthetic resin integrally and is formed into an elongated rectangular plate shape. A disc-shaped hitting piece 5 is formed on the tip end surface of the swing rod 3. The striking piece 5 is integrally formed in a shape in which a flat surface portion of a disc is joined to a tip end surface of the swing rod 3.

A modeled body 4 imitating an animation character, an animal, a motif related to various sports (for example, a baseball ball, a soccer ball, etc.) is attached near the tip of the swing rod 3.

On the rear end side of the swinging rod 3, mounting holes 90, 91 are formed for the mounting bosses 83a (83b), 84a (84b). Reinforcing ribs 92 are formed on the periphery of the rear end portion of the swinging rod 3 near the mounting holes 90 and 91 so as to be perpendicular to the plate-like surface of the swinging rod 3. In the present embodiment, the reinforcing ribs 92 are formed on one side of the swing rod 3, but they may be formed on both sides.

Next, the relationship between the cylindrical body 1, the grip body 2, and the swing rod 3 described above will be described in the order of assembly with reference to FIGS. 4 to 7.

First, the swing rod 3 is inserted from the front end opening of the tubular body 1 to a position where the rear end of the swing rod 3 projects from the rear end opening of the mounting cylinder 6 (FIG. 4). At this time, in the first embodiment to be described later, the shaped body 4 is inserted up to a position where it can be projected from the slot 12 formed in the peripheral wall of the tubular body 1. Then, as shown in FIGS. 5 and 6, the notches 23a and 27a of the upper body 21 are engaged with the mounting cylinder 6, and the mounting bosses 83a of the upper body 21 are fitted into the mounting holes 90 and 91 of the swing rod 3. Insert 84a. At this time, the swing rod 3 is pushed into the mounting bosses 83a, 84a until it comes into contact with the supporting surface 86 which is the end of the supporting rib 88 radially formed on the peripheral wall of the mounting bosses 83a, 84a. In this state, the tip ends of the mounting bosses 83a, 84a project from the mounting holes 90, 91.

When the lower body 22 is joined to the upper body 21 with the above-mentioned body, the tubular body 1, the grip body 2, and the swing rod 3 are all joined together, and the appearance is a megaphone shape. . Then, the upper body 21 and the lower body 22 are fixed by the fixing screws 95, whereby the megaphone of the present invention is completed.

The joining of the upper body 21 and the lower body 22 will be described in more detail. As shown in FIG. 7, counterbore portions 94 are formed at the tips of the mounting bosses 83b and 84b. The front end of the mounting bosses 83a and 84a, which protrude through the mounting holes 90 and 91 of the swing rod 3, are fitted into the spot facing portion 94 so as to be inserted. With this structure, when the upper body 21 and the lower body 22 are joined, first, the rear end wall 14 of the tubular body 1, the mounting barrel 6 and the locking portion 62 are used to attach the mounting plate 24a of the upper body 21 and the lower body 22. , 24b and the cutouts 23a, 23b, 27a, 27b of the ribs 25a, 25b, the grips 2 are held by the tubular body 1.

Next, the swing rod 3 is fixed by the mounting bosses 83a and 84a of the upper body 21 so as not to move in the longitudinal direction. Further, the swing rod 3 is sandwiched between the support surface 86 of the support rib 88 formed around the mounting bosses 83a and 84a and the end surface of the mounting bosses 83b and 84b of the lower body 22, and is vertically moved. It is fixed so that it does not exist.

With the above configuration, the megaphone of the present invention described above can be used as a megaphone for expanding the voice as a normal use. Secondly, it can be used as a sound generator instead of clapping or clapping. In other words, by swinging the megaphone, the swing rod 3 swings inside the tubular body 1 around the portion fixed by the grip body 2, and the striking piece 5 provided at the tip of the swing rod 3 becomes the barrel. The inner wall of the body 1 is tapped to generate a sound. Thirdly, as the swing rod 3 swings, the shaped body 4 such as a doll provided on the swing rod 3 moves along with the swing of the swing rod 3. You can enjoy the movement of the model (visual effect) as well as the effect.

You can As a result, when watching sports, in addition to the megaphone function as a loudspeaker, an acoustic stimulus is generated by a striking sound instead of clapping, and the doll body (model 4) is fun to see. The visual effect can also be generated.

A second embodiment of the present invention will be described with reference to FIGS. 8 and 9. The basic structure is the same as that described in the embodiment of the invention, but a part mainly relating to the swing rod 3 is different. In the first embodiment, the entrance / exit opening 12 is formed in the peripheral wall portion of the tubular body 1, but in the second embodiment, the entrance / exit opening is not formed. This is because the swing rod 113 is formed to have a length longer than that of the swing rod 3 used in the first embodiment, and the shaped body 114 swings outside the cylindrical body 111. It

The swing rod 113 will be described in more detail. The method of fixing the swing rod 113 to the grip body 112 is the same as that described in the embodiment of the invention. On the other hand, the tip end side of the swing rod 113 is formed to have a length that protrudes from the tip end opening 104 of the tubular body 111, unlike the one described in the first embodiment. An L-shaped mounting base 120 is formed at the tip of the swing rod 113 for mounting the shaped body 114. A striking piece 115 protruding in the swinging direction of the swinging rod 113 is provided at a position surrounded by the tubular body 111 of the swinging rod 113, and slightly toward the rear end direction from the front end opening 104. Has been formed. The striking pieces 115 are rectangular plates and are formed on both front and back surfaces of the swing rod 113 so as to stand upright at right angles to the swing rod 113. The shape and the like of the striking piece 115 need not be limited to the shape and the like of the second embodiment, as long as the inside of the cylindrical body 111 can be tapped when the swing rod 113 swings. Such a structure may be used.

The tip of the swing rod 113 will be further described. An L-shaped mounting base 120 for mounting the shaped body 114 is formed at the tip of the swing rod 113. The mounting base 120 has the same effect as that when the tip end of the swing rod 113 is coupled near the center of the shaped body in order to swing the shaped body 114 evenly with respect to the tubular body 111. It was created for this purpose. Further, the tip end surface of the swing rod 113 may be directly coupled to the vicinity of the center of the shaped body 114 without forming a mounting base (not shown).

Dimensionally, the total length of the megaphone 1B is about 30 cm, and the total length including the protruding rocking rod 114 is about 35 cm. The outer diameter of the tubular body 1 is about 10 cm, and the diameter of the portion of the grip body 2 having a small outer diameter is about 2.4 cm.

In the second embodiment, the basic effect is the same as that of the first embodiment, but a doll or the like (model 114) swings outside the tubular body 111. Therefore, in the first embodiment, the doll or the like can be seen only when the doll or the like projects from the tubular body, but in the second embodiment, the doll or the like can be seen at all times and This is an effect different from that of the first embodiment in that the motion by rocking can be enjoyed.
