本発明は布帛、皮革等のシート状物を均一に強く緊張す
る方法及びその装置に係り特に打楽器、三味線等の楽器
類の皮張りに好適に利用し得ることを目的とするもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for uniformly and strongly tensioning a sheet-like material such as cloth or leather, and an object of the present invention is to make it suitable for use in applying the leather to musical instruments such as percussion instruments and shamisen. That is.
従来、シート状物の緊張は被緊張材料を円周に沿って端
を固く保持し、て引張ることにより緊張を与えるのみで
あるため、外周に近い程緊張度が高く、中心部になるに
従って緊張度が小さくなる。Conventionally, tensioning of a sheet-like material is simply done by firmly holding the edge of the material to be tensioned along the circumference and pulling it, so the tension is higher near the outer periphery, and the tension increases as you move toward the center. The degree becomes smaller.
従って被緊張材料の面積が大きい程中央部は無緊張に近
い状態のま5にとどまっている。Therefore, the larger the area of the material to be tensioned, the more the central portion remains in a state close to zero tension.
均一な緊張が得られないシート状物は使用時の打音が鈍
く、無緊状態であるため緩みを生じるという欠点がある
。A sheet-like material that cannot be tensioned uniformly has the disadvantage that it produces a dull tapping sound during use, and that it loosens because it is not tensioned.
本考案は従来の欠点を改良した被緊張物に均一な緊張を
付与する緊張装置を提供する。The present invention provides a tensioning device that applies uniform tension to an object to be tensioned, which overcomes the drawbacks of the prior art.

状物の緊張装置である。That is, the present invention holds and fixes the periphery of the material to be strained, and applies multi-step pressure perpendicularly to the material to be strained in stages from near the center outwards to uniformly tension the entire material. A method for tensioning a sheet-like object and a device directly used to carry out the method, which includes a holding device for fixing the outer periphery of the material to be strained, and a device for vertically facing the material to be strained held by the holding device. and a pressing part provided at the tip of a shaft that can protrude from the material, and the pressing part is provided in multiple stages to sequentially press the material to be stretched from the center to the outer circumference. .
以下、本発明を図面を用いて説明する。Hereinafter, the present invention will be explained using the drawings.
第1図は本考案の実施の一例を示す平面図で、被緊張材
料9の外周を保持装置で水平方向に固定する。FIG. 1 is a plan view showing an example of the implementation of the present invention, in which the outer periphery of the material 9 to be tensioned is fixed in the horizontal direction by a holding device.
即ちフレーム7に設けられたクリップ8で水平方向にや
や緊張させて張り付ける。That is, it is attached with a clip 8 provided on the frame 7 with a slight tension in the horizontal direction.
クリップ8はフレーム7に適宜間隔で取付けられて被緊
張物を保持する。The clips 8 are attached to the frame 7 at appropriate intervals to hold an object to be tensioned.
また多段押圧は第2図に示す如く、被緊張材料9に対し
垂直方向に圧力を加える。Further, in the multi-stage pressing, pressure is applied in the vertical direction to the material 9 to be strained, as shown in FIG.
該装置はシリンダー4.5,6で上下に被緊張材料9に
対し垂直に移動をなすもので、被緊張材料の中央部付近
をまず押圧する軸12aの先端に設けられた中央押圧部
1、この中央押圧部を中心に外側に向って順次軸12b
の先端に設けられた中段押圧部2及び軸12cの先端に
設けられた後段抑圧部3から構成される。This device moves up and down perpendicularly to the material to be tensioned 9 using cylinders 4, 5, 6, and includes a central pressing portion 1 provided at the tip of a shaft 12a that first presses the vicinity of the center of the material to be tensioned; The shaft 12b is sequentially moved outward around this central pressing part.
It is composed of a middle stage pressing part 2 provided at the tip of the shaft 12c and a rear stage suppressing part 3 provided at the tip of the shaft 12c.
このそれぞれの押圧部は保持装置で水平方向に緊張され
ている被緊張物に対し、垂直方向に段階的に多段押圧作
用することが均一な緊張を与える。Each of the pressing portions exerts a multi-stage pressing action in the vertical direction on the object to be tensioned, which is being tensioned in the horizontal direction by the holding device, thereby uniformly tensioning the object.
第1段の抑圧に対し、第2段の押圧は該周囲を段階的に
行うものでなければならない。In contrast to the first stage of compression, the second stage of pressing must be applied to the surrounding area in stages.
この抑圧部の段数は三段に限定されるものでなく、被緊
張物の大きさにより、段数を増すことも出来る。The number of stages of this suppressing section is not limited to three stages, and the number of stages can be increased depending on the size of the object to be stretched.
抑圧は第2図の如く、上昇させる形式でもよく、また逆
に下降させるものであってもよく、被緊張材料に対し垂
直に対するものであればよい。The compression may be of a rising type as shown in FIG. 2, or may be of a lowering type, as long as it is perpendicular to the material to be strained.
次に本発明の作用について説明する。Next, the operation of the present invention will be explained.
まず被緊張材料の周囲をクリップ8で水平に保持する。First, the periphery of the material to be strained is held horizontally with the clip 8.
しかる後、該水平に保持した被緊張物と垂直方向に位置
する抑圧部L2,3で順次中央部付近より外側に向って
抑圧を加える。Thereafter, suppression is sequentially applied from the vicinity of the center toward the outside using the suppression sections L2 and 3 located perpendicularly to the horizontally held object to be strained.
この押圧部1,2゜3による押圧順序としては、まず中
央抑圧部1のシリンダー4を作動させて被緊張物9の中
央部附近qを緊張させる。The order of pressing by the pressing parts 1, 2 and 3 is as follows: first, the cylinder 4 of the central suppressing part 1 is operated to tension the central part q of the object 9 to be tensioned.
次いで中段抑圧部2のシリンダー5を作動させて中央押
圧部1よりやや上昇又は下降させて中央部附近9′の周
囲rに緊張を与え、最後に後段押圧部3を上昇又は下降
させて外側に緊張を与える。Next, the cylinder 5 of the middle stage suppressing part 2 is operated to raise or lower it slightly from the central pressing part 1 to apply tension around the vicinity 9' of the central part, and finally, the rear stage pressing part 3 is raised or lowered to move it outward. give tension.
このように被緊張物に順次中央部付近より外側に向って
多段押圧を与えることによって緊張物全体に均一な緊張
を与えることが出来る。In this way, by sequentially applying multi-stage pressure to the object to be strained from the vicinity of the center toward the outside, it is possible to apply uniform tension to the entire object to be strained.
このようにして得られた緊張物は、第3図に示す如く、
例えば張り枠10に一定の緊張を保持したまま接着剤1
1で固定して枠張り人工シート状物形成物として、打楽
器弦楽器の皮交替に簡便に使用する。The tension material obtained in this way is as shown in Fig. 3.
For example, while maintaining a certain tension on the tension frame 10,
1 to form an artificial sheet-like article, which can be easily used to replace the skin of a percussion instrument or a stringed instrument.
本考案で緊張する被緊張物としては打楽器用の皮革、人
