Utility model registration No. 3195495

  The above-mentioned Patent Document 1 discloses a new drum-type percussion instrument that has never been found, but there is still room for improvement. One of them is as follows. In conventional percussion instruments, mallet type bees have their heads made of a hard material made of wood or resin in order to suppress the natural vibrations of the bees themselves. For this reason, in order to vibrate the musical instrument, a buffer layer is required at the contact portion with the striking surface, and the head portion must be covered with soft felt, wool, cloth, or the like. Along with this, since several kinds of materials are used for manufacturing, there is a problem that the entire bee becomes heavy and the manufacturing process increases.

  Accordingly, the present invention has been made in view of such problems, and an object of the present invention is to provide a new and improved bee and a drum-type percussion instrument employing the bee. .

  In order to solve the above problems, according to the present invention, a bee comprising a handle and a head having a diameter larger than that of the handle, wherein the head has a honeycomb core structure or a truss structure. Provided. In addition, a honeycomb (honeycomb) means a beehive in English, and a structure in which hexagons such as a honeycomb and other same three-dimensional figures (cells) are arranged without a gap is called a honeycomb core structure. The truss structure refers to a structure composed of aggregates with a triangle as a basic unit.

  According to this structure, the head part which does not require a buffer layer only with one raw material can be made by making the head part of a bee into a structure which has a honeycomb core structure or a truss structure. With such a configuration, the natural vibration of the head can be effectively reduced, and the size and weight of the bee can be reduced. Moreover, since the structure is simple, it can be manufactured easily and inexpensively.

  Further, according to the present invention, it comprises a hollow cylindrical or polygonal columnar body part, and a striking surface part provided at the top of the body part, the body part from the surface toward the inside, An accommodating portion capable of accommodating a bee is provided, wherein the bee includes a handle and a head having a diameter larger than that of the handle, and the head has a honeycomb core structure or a truss structure. A drum-type percussion instrument is provided.

  According to such a configuration, by providing the accommodating portion capable of accommodating a bee (rod-like body) from the surface of the body portion toward the inside, a part or all of the rod-like bee is accommodated in this accommodating portion. Can do. The provision of such a housing is an advantage of a drum-type percussion instrument, and such a configuration is impossible with a drum as a conventional general instrument. According to the present invention, it is possible to effectively prevent the loss and forgetting of bees by making use of the unique characteristics of a drum-type percussion instrument.

  The present invention can be applied in various ways. For example, the striking surface portion includes a first striking surface portion and a second striking surface portion provided so as to face both ends of the body portion, and the first striking surface portion and the second striking surface portion include The thickness may be different.

  In the present invention, various materials can be used as the drum-type percussion instrument for the hitting surface. If a thicker material is used for the hitting surface, the pitch will be higher, and if a thinner material is used, the pitch will be lower. Therefore, if materials having different thicknesses (for example, cardboard) are used on both sides of the striking surface, it is possible to perform with a wide range of sound.

  According to the present invention, it is possible to provide a new and improved bee and a drum-type percussion instrument employing the bee. Other effects of the present invention will also be described in the following section for implementing the present invention.

(First embodiment)
A drum-type percussion instrument 100 according to an embodiment of the present invention will be described. First, the configuration of the drum-type percussion instrument 100 will be described mainly with reference to FIGS.

  FIG. 1 is a diagram schematically showing the configuration of a drum-type percussion instrument 100. As shown in FIG. 1, the drum-type percussion instrument 100 has a hollow cylindrical body 110, percussion surfaces 120 and 130 provided on the top of the body 110, and a drum-type percussion instrument 100 for holding the drum-type percussion instrument 100 by hand. The strap 140 is mainly provided. And the body part 110 accommodates the bee 150 from the surface toward the inside.

  The size of the drum-type percussion instrument 100 is arbitrary, but in the present embodiment, as an example, the size that allows the drum-type percussion instrument 100 to be held and held by the palm of the hand is about 10 to 18 cm in diameter. Hereinafter, each component of the drum-type percussion instrument 100 will be described in order.

(Body part 110)
As shown in FIG. 1, the body part 110 has a hollow cylindrical shape. The diameter of the cylinder of the torso part 110 is a size (about 10 to 18 cm) that is the extent to which the palm is spread. As shown in FIG. 1, the interior of the body portion 110 constitutes a housing portion for housing the bee 150. As described above, in the present embodiment, the hollow columnar inside of the body portion 110 functions as a housing portion for the bee 150.

  The body part 110 can be configured using, for example, a thick (paper thickness: 0.7 mm, basis weight 400 g / m 2) three-layer kraft paper (cardboard). Dense vertical grooves are provided at intervals of about 0.8 mm inside the body portion 110, and a cylindrical shape can be formed by the vertical grooves as shown in FIG. However, the material of the body part 110 is not limited to this example, and for example, it may be composed of a multilayer paper (corrugated cardboard) or a synthetic resin material.

  FIG. 2 is a diagram illustrating a state in which the body portion 110 is developed. As shown in FIG. 2, the body part 110 in the unfolded state has a long rectangular shape, and joints 118a and 118b are formed at both ends. By joining the joint portions 118a and 118b, the cylindrical shape of the body portion 110 shown in FIG. 1 is configured.

  As shown in FIG. 2, a bee-accommodating hole 112 for storing the bee 150 in the body 110 is provided at the center of the body part 110 in the unfolded state, and strap holes 114 are provided at both ends thereof. 116 are provided. As shown in FIG. 1, the bee 150 is inserted into and accommodated in the hole for accommodating bee 112. Further, as shown in FIG. 1, the strap 140 is inserted into the strap perforations 114 and 116. The strap 140 will be further described later.

(Striking surface portion 120, 130)
As shown in FIG. 1, the hitting surface portions 120 and 130 have a disk shape and are provided so as to face both upper and lower ends of the body portion 110. The disc-shaped diameters of the hitting surface portions 120 and 130 correspond to the size of the body portion 110. The hitting surface 120 can be composed of multilayer paper (corrugated cardboard). Like paper cones (papermaking diaphragms) used in general acoustic speakers, paper is a material suitable for voice sources. However, the striking surface portion 120 may be composed of other materials, for example, synthetic resin or plywood.

  In the present embodiment, the striking surface portion 120 and the striking surface portion 130 are configured to have different material thicknesses. When a thick material is used for the hitting surface portions 120 and 130, the pitch is increased, and when a thin material is used, the pitch is decreased. By using materials having different thicknesses for the striking surface portion 120 and the striking surface portion 130, it is possible to perform with a wide range of sounds. In this way, a unique drum-type percussion instrument 100 in which the pitch of the sound is varied depending on the surface hit with the bee 150 can be realized.

  In joining the body part 110 and the hitting surface parts 120 and 130, the peripheral part (outer periphery) of the hitting surface parts 120 and 130 is directly joined to the top part of the body part 110 in order to reduce the low frequency range and extend the sound of high sounds. Is done. By doing in this way, generation | occurrence | production of the low frequency by striking vibration can be suppressed, and a clear high sound can be obtained.

(Strap 140)
The strap 140 is for holding the drum-type percussion instrument 100 on a finger. As shown in FIGS. 1 and 2, both ends of the strap 140 are attached to the trunk portion 110 through the strap holes 114 and 116 from the outside of the trunk portion 110. The strap 140 can be brought into close contact with the outer periphery of the body portion 110 by pushing the strap 140, so that the portions of the strap 140 that are outside the strap perforations 114 and 116 are exposed.

  The material of the strap 140 is arbitrary, but for example, a nylon cord or the like can be used. As described above, since the different sounds can be produced by the striking surface portion 120 and the striking surface portion 130, the direction of the drum-type percussion instrument 100 may be reversed while a finger is passed through the strap 140. In order to give the strap 140 such a function, an appropriate material can be adopted in consideration of appropriate softness and strength.

  The configuration of the drum-type percussion instrument 100 has been described above. Next, the bee 150 that is an accessory of the drum-type percussion instrument 100 will be described. When actually distributing the product as a product, the taiko-type percussion instrument 100 and the bee 150 may be individually targeted for commercial transactions, or the taiko-type percussion instrument 100 and the bee 150 may be set as a taiko-type percussion instrument. It may be a target.

(Bee 150)
3A and 3B are views showing the bee 150, FIG. 3A is a view of the bee 150 viewed from the side, and FIG. 3B is a view of the head 154 viewed from above. As shown in FIG. 3A, the bee 150 is mainly composed of a rod-shaped (long-shaped) handle 152 and a head 154 having a larger diameter than the handle 152.

  The handle 152 is a portion that is held by the user of the drum-type percussion instrument 100 during performance. The material and size of the handle 152 are determined in consideration of the ease of being held by the user, the degree of bending of the handle 152, the convenience during storage, and the like. For example, the material of the handle 152 is bamboo or wood. Further, as shown in FIG. 1, the length of the handle 152 is a length that can be accommodated in the body portion 110 and can be easily held during performance, for example, about 11 cm. Further, the thickness of the handle 152 is a thickness that can pass through the hole for accommodating bees 112. For example, the thickness can be about 3 mm.

  The head 154 is provided at the tip of the handle 152 as shown in FIG. Then, the handle 152 and the head 154 are fixed by inserting the tip of the handle 152 into the center of the head 154. The head 154 is configured to have a larger diameter than the handle 152. For example, the diameter can be about 2.5 cm and the height can be about 1 cm.

  That is, the handle 152 can be inserted through the bee-accommodating perforation 112, but the head 154 is configured not to insert the bee-accommodating perforation 112. Thereby, the loss and forgetting of the bee 150 can be effectively prevented by accommodating the handle 152 in the body part 110. In addition, since the head 154 has a larger diameter than the handle 152, the head 154 can be prevented from being housed in the body 110, and the bee 150 can be easily taken out.

  The head 154 is a paper honeycomb core formed and laminated in a cylindrical shape as shown in FIG. Like paper cones (paper-making diaphragms) used in general acoustic speakers, internal loss (the rate at which the material absorbs vibration) increases in the configuration using paper materials, and the head is unique. Vibration can be effectively suppressed. In addition, a honeycomb (honeycomb) means a beehive in English, and a structure in which hexagons such as a honeycomb and other same three-dimensional figures (cells) are arranged without a gap is called a honeycomb core structure. By configuring the head 154 with a honeycomb core, it is lightweight and rich in elasticity, and it is possible to play quite fine notes using bound percussion sounds. For example, it is possible to perform the same performance as a percussion instrument called a percussion instrument or a percussion instrument.

  Further, the head 154 has durability against impact by impregnating the peripheral edge of the honeycomb core with resin such as urethane. As described above, the head 154 can be light and strong.

  As described above, according to the present embodiment, unlike the case of a typical drum and bee, the bee 150 can be accommodated in the drum-type percussion instrument 100, so that the bee 150 is not easily lost.

Heretofore, a configuration example of this embodiment has been described.
Next, a method of using the drum-type percussion instrument 100 will be described mainly with reference to FIG. FIGS. 4A and 4B are diagrams showing an example of use of the drum-type percussion instrument 100. FIG. 4A shows a case where a bee 150 is taken out, FIG. 4B shows a case where a finger is put on the strap 140, and FIG. The state where the drum-type percussion instrument 100 is being struck is shown.

  When the drum-type percussion instrument 100 is stored without using it, the drum 150 is accommodated in the drum-type percussion instrument 100. When using the drum-type percussion instrument 100, the user takes out the bee 150 from the drum-type percussion instrument 100 as shown in FIG.

  Then, as shown in FIG. 4B, the user passes the strap 140 through the finger of one hand and supports the drum-type percussion instrument 100 with the palm of the hand. As described above, the drum-type percussion instrument 100 has a diameter of about 10 to 18 cm, and can be appropriately supported by the palm through the strap 140.

  Then, as shown in FIG. 4C, the user can play the drum-type percussion instrument 100 with the extracted bee 150. As described above, by using materials having different thicknesses between the striking surface portion 120 and the striking surface portion 130, it is possible to perform with a wide sound range. The pitch of the sound can be varied depending on the surface hit with the bee 150.

  When the direction of the drum-type percussion instrument 100 can be reversed with a finger passing through the strap 140, the pitch of the sound can be changed by replacing the percussion surface portions 120 and 130. If the direction of the drum-type percussion instrument 100 cannot be reversed while the finger is passed through the strap 140, the drum-type percussion instrument 100 can be reversed by removing the finger from the strap 140.

(Effects of the first embodiment)
As described above, according to the present embodiment, by providing the accommodating portion that can accommodate the bee 150 from the surface of the body portion 110 toward the inside, the rod-shaped bee 150 is accommodated in the accommodating portion. be able to. The provision of such a housing is an advantage of the drum-type percussion instrument 100, and such a configuration cannot be achieved with a drum as a conventional general musical instrument. According to the present embodiment, it is possible to effectively prevent the loss and forgetting of the bee 150 by making use of the characteristics unique to the drum-type percussion instrument 100.

  Further, the striking surface portion 120 and the striking surface portion 130 are configured to have different thicknesses, so that a performance with a wide range can be performed.

  Moreover, the loss of the bee 150 can be effectively prevented by accommodating the handle 152 in the accommodating portion. Moreover, by providing the head 154 having a diameter larger than that of the handle 152, the portion of the head 154 can be prevented from being accommodated in the accommodating portion, and the bee 150 can be easily taken out from the accommodating portion. Furthermore, by configuring the head 154 with a honeycomb core, it is lightweight and rich in elasticity, and it is possible to play a rather fine note using a bounce sound.

(Second Embodiment)
In the first embodiment, the honeycomb-type head 154 has been described as an example of the configuration of the head 154 of the bee 150 (FIG. 3). In this embodiment, another configuration example of the bee will be described. The head of the bee of this embodiment has a structure called “truss type” as will be described below. Description will be made mainly with reference to FIG.

  The bee of this embodiment is a substitute for the bee 150 (FIG. 3) described in the first embodiment, and the shape of the head of the bee is different. As shown in FIGS. 5A and 5B, the head of the bee of this embodiment has a truss structure. The truss structure refers to a structure composed of a collection of triangles as a basic unit.

  As shown in FIG. 5A, the truss structure includes a double truss structure in which a triangular portion is formed in a double shape, and a spiral structure. FIG. 5B shows another example of the truss structure, which is a structure in which an inner triangle and an outer double triangle are combined. Thus, it is good also as a structure which combined the normal truss structure, the double truss structure, or the spiral structure. Other features of the head (material other than the shape, etc.) are substantially the same as those of the head 154 of the first embodiment.

  According to the present embodiment, the head of a bee that is light and strong can be obtained. Note that portions other than the configuration described in the present embodiment can be configured substantially the same as those in the first embodiment, and thus redundant description is omitted.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It is obvious for those skilled in the art that various changes or modifications can be conceived within the scope described in the claims for utility model registration, and these naturally belong to the technical scope of the present invention. It is understood.

  For example, although the case where the trunk | drum 110 was a cylindrical shape was demonstrated in the said embodiment, this invention is not limited to this. For example, the shape of the body portion may be a polygonal column shape. In this case, it goes without saying that the shape of the hitting surface portion is a shape that matches the shape of the body portion.

  Moreover, although the said embodiment demonstrated the structure which consists of the hitting face part 120 and the hitting face part 130 from which the thickness of a raw material differs, this invention is not limited to this. The striking surface portion 120 and the striking surface portion 130 may be made of the same material and thickness. Further, for example, unlike the striking surface portion 120 and the striking surface portion 130, the striking surface portion may not be provided at both ends of the body portion 110, but only one surface may be a striking surface portion and the other surface may not have a striking surface portion.

  Moreover, although the said embodiment demonstrated the structural example which provides the strap 140 in the drum-type percussion instrument 100, this invention is not limited to this, The strap 140 does not necessarily need to be provided.

  Moreover, although the specific structure of the bee 150 was demonstrated in the said embodiment, this invention is not limited to this, The bee of arbitrary structures can be employ | adopted. Note that at least a part of the bee (for example, only the pattern portion) may be accommodated in the drum-type percussion instrument, or the entire bee may be accommodated in the drum-type percussion instrument. Moreover, the shape of the accommodating part is also arbitrary. The entire inside of the drum-type percussion instrument may be hollow, or may be a housing portion having a shape corresponding to the shape of the bee.

  Furthermore, in order to make it difficult for the bee 150 to come off, some type of locking mechanism may be provided in the housing portion. In the above embodiment, the bee 150 and the strap 140 are described as independent components, but the loss of the bee 150 may be more effectively prevented by connecting the bee 150 and the strap 140. . In this way, it is possible to effectively prevent the loss and forgetting of the bees.

  The present invention can be used for bees and drum-type percussion instruments.
