Description

  The present invention relates to a megaphone grip part as a sporting support tool and a megaphone having the megaphone grip part, and more particularly, a grip when the grip part fits the shape of the grip hand and hits the megaphone with another hand. For things that are stable.

  For example, as shown in FIG. 4, the conventional megaphone is composed of a loudspeaker tube 80 and an air outlet 81. When the megaphone 8 is used as a sporting support tool or the like, the air outlet 81 is blown or the megaphone 8 is held with one hand. In general, the cylinder 80 is hit with the other hand to generate a sound. Reference numeral 82 denotes a string, and reference numeral 83 denotes a constricted portion of the megaphone 8.

As a megaphone invented mainly for the purpose of making it possible to enjoy watching a game by emitting this hitting sound, there is the invention of “megaphone” of Japanese Patent No. 3099284, which is the patent of the present applicant. This is a megaphone characterized in that a plurality of loudspeakers have one grip part shared by the rear part, and a plurality of loudspeakers are provided so as to strike each other by striking. . By grasping the one grip portion with one hand and striking the plurality of loudspeakers with the other hand, a loud striking sound can be emitted.
Japanese Patent No. 3099284 (FIG. 3)

  Now, with any megaphone that uses a megaphone loudspeaker to generate sound, one of the conditions for producing a good sound is the grip certainty when gripping the grip with your hand. Although it is required, for example, as understood from a state in which the grip part is gripped only by the thumb and index finger, a good striking sound cannot be produced in a state where the grip part is not tightly fitted to the hand. Also, if the grip is not certain, there will be a problem that the megaphone will fall out of the hand and drop when supporting the megaphone.

  In this case, the shape of the grip portion of the conventional megaphone is generally cylindrical and does not fit the shape of the palm side when the hand is gripped (such as the megaphone 9 and the blowing port as in the megaphone 9 in FIG. 5). In addition, in the megaphone 8 described above, in the type in which the constricted portion 83 between the loudspeaker tube 80 and the air outlet 81 is gripped in the megaphone 8 described above, the gripping portion is held by the thumb or index finger. Since it hits a part that becomes thicker than the constricted part 83, there is a problem that the grip of the thumb or index finger becomes sweet. In short, the shape of the grip portion of the conventional megaphone does not fit the shape of the palm side when the hand is held.

  Accordingly, the object of the present invention is to solve the above-mentioned problems and strike the megaphone by hand by making the shape of the grip portion of the megaphone fit the shape of the palm side when the hand is gripped. It is an object to stabilize the grip when performing. In addition, we would like to solve the problem of lack of interest due to the conventional grip shape of megaphone.

  Prior to solving the above-mentioned problems, the present inventor carefully observes the state of gently grasping the hand without using the megaphone, and the line composed of four fingers from the index finger to the little finger and the area around the thumb ball. I got the knowledge that the line is almost C-shaped. In addition, it has been found that this substantially C-shape has an angle that opens on the thumb ball side with respect to the center line of the grip as compared to the line on the side composed of four fingers.

  Therefore, the above-mentioned problem is a megaphone grip part composed of a loudspeaker tube and a mouthpiece, and the shape of the grip part is a line where the four fingers from the index finger to the little finger are in contact with the line where the thumb ball is in contact. So that the line on the side where the thumb ball is in contact with the center line of the grip part is opened at an angle wider than the line on the side where the four fingers are in contact. This is achieved by using a formed megaphone grip. Such a grip portion is applied to an arbitrary megaphone.

  In addition, in the megaphone including the loudspeaker tube, the mouthpiece, and the grip portion, the above-mentioned problem is that the shape of the grip portion is a line where the four fingers from the index finger to the little finger are in contact with a line where the thumb ball is in contact. So that the line on the side where the thumb ball is in contact with the center line of the grip part is opened at an angle wider than the line on the side where the four fingers are in contact. This is achieved by using a formed megaphone.

  When the hand is held as described above, the line composed of four fingers from the index finger to the little finger and the line around the thumb ball are substantially C-shaped, and the center line of the grip is As a standard, the thumb ball side line is more open than the four finger side line, but the shape of the grip is matched to this shape. The shape of the part fits snugly into the shape on the palm side when the hand is held, a stable grip and a stable grip feeling are obtained, and the hit on the loudspeaker tube becomes stable.

  Although this effect can be applied to any megaphone, a plurality of loudspeakers are provided so as to strike each other by hitting, mainly for the purpose of hitting, as in the “megaphone” of Japanese Patent No. 3099284. In the case of the thing, a firmer sound can be generated by stabilizing the grip.

  Moreover, the shape of the grip itself is very unique and interesting.

  Further, when the grip portion of the megaphone is provided with a non-slip, there is an effect that the grip becomes more stable. For this purpose, irregularities may be formed in the grip portion, or a rubber sheet may be attached to the grip portion.

  Next, in the megaphone according to the present invention, the grip portion can be provided at the air outlet. It is possible to reduce the size of the megaphone as a whole by the grip portion being a blower. In addition, in the type of megaphone in which the grip portion is between the loudspeaker tube and the mouthpiece, the mouthpiece may hit the base of the hand when swinging or hitting, but this does not occur due to the grip portion being the mouthpiece. You can feel as if you are playing a megaphone made with palms.

  Next, in the megaphone according to the present invention, a plurality of loudspeakers have one grip part shared by the rear part thereof, and a plurality of loudspeakers are provided so as to strike each other by striking. It can be. This action has already been explained in the item 0011.

  According to this invention, the shape of the grip portion of the megaphone is formed in a substantially C shape by the line on the side where the four fingers from the index finger to the little finger contact and the line on the side where the thumb ball contacts, With respect to the center line of the grip portion, the line on the side in contact with the thumb ball is formed so as to have an open angle than the line on the side in contact with the four fingers. This shape is a substantially C-shape consisting of a line composed of four fingers from the index finger to the little finger and a line around the thumb ball when the hand is lightly grasped without using a megaphone. And the fact that this substantially C shape is more open than the line of the four fingers on the thumb ball side with respect to the center line of the grip, the grip portion of the megaphone It fits very well in the shape of the palm side when it is gripped, and has an excellent effect that the grip when hitting the megaphone is really well stabilized. Moreover, the shape of the grip itself is very unique and interesting.
