Description

本発明は帯状に形成されたプラスチック製や金属製のバンドを電柱への取り付けや、荷造りに用いる際の締付具に関するものである。   The present invention relates to a fastener when a plastic or metal band formed in a band shape is attached to a power pole or used for packing.

上記のようなバンド締付具において、締付具本体にバンド締付用の回動レバーを回転可能に取付け、その回動レバーのバンド巻込み軸近傍にバンド挿通孔を形成し、上記締付具本体に一端を折返し固定したバンドの他端を、締付具本体に対して回動レバーを開いた状態で、レバー後方から直線的にバンド挿通孔に通して上記回動レバーを締付具本体側に回転させ閉じることによってバンドを巻込み、締付けるようにしたものは知られていた。   In the band clamp as described above, a rotation lever for band tightening is rotatably attached to the clamp body, and a band insertion hole is formed in the vicinity of the band winding shaft of the rotation lever. With the other end of the band, one end of which is folded back and fixed to the tool body, with the rotating lever opened relative to the fastener body, the above lever is tightened by passing straight through the band insertion hole from the rear of the lever. It has been known that a band is wound and tightened by rotating and closing to the main body side.

特開平10−9222号JP-A-10-9222

これら従来の締付具は回動レバーを閉じるに従い、バンド張力がどんどん増加し最終締付時に過大な負荷を要した。従来は可撓性バンドの固定に使用されていた為、締付は可能であったが伸びのほとんど無いポリエステル製のバンドやステンレスバンド等の締付に使用することは不可能であった。
さらに回動レバー挿通孔に通したバンドは自在のままで、このバンドを片手で固定しながら回動レバーを回す必要があった。
これまでもラチェット構造の金属製の締付具を利用すると伸びの無いバンドの締付は可能であったが、これらの締付具は構造が複雑であった。
With these conventional fasteners, the band tension increased as the rotating lever was closed, and an excessive load was required at the time of final fastening. Conventionally, since it was used for fixing a flexible band, tightening was possible, but it was impossible to use it for tightening a polyester band or a stainless steel band that hardly stretched.
Furthermore, the band passed through the rotation lever insertion hole remains free, and it is necessary to turn the rotation lever while fixing the band with one hand.
In the past, when a metal fastener having a ratchet structure was used, it was possible to fasten a band that did not stretch, but these fasteners had a complicated structure.

片方のバンドを係止しバンド巻込み用の回動レバーを受ける軸受けを有する締付具本体に、バンド巻込み軸近傍にバンド用の挿通孔を設けた回動レバーを取り付けたバンド締付具において、締付け具本体には回動レバーの回転に従って回転軸が後方上からバンド引張り下方向へ摺動するべく傾斜した台形の軸受けを有し、回動レバーのバンド巻込み軸はカムの形状をし、回動レバーが開かれた状態でバンド挿通孔へ通す際バンドは挿入方向へ鋭角に折返す方向になる様にバンドの厚さより僅かに広い挿通孔がカム形状先端に向かって設置され、かつ回動レバーの回転に従いバンドの固定とカム形状に沿った巻込みが促され、カム形状先端が締付け具本体底面を通過後にはカム形状と本体軸受けの傾斜とにより回動レバーはバンド引張り下方向へ降下しレバーの戻りに対抗する位置関係となりバンドを押えこむように構成されていることに特徴があり、形状が簡単で作製し易く、仮締めから回動レバーの本体への閉止まで過大な力を必要とせず作動し、バンドが大きな力で引張られても簡単には係止解除されないバンド締付具となる。   A band fastener in which a rotation lever provided with a band insertion hole in the vicinity of a band winding shaft is attached to a clamp body having a bearing for locking one band and receiving a rotation lever for winding the band. The clamp body has a trapezoidal bearing whose rotary shaft is inclined so as to slide downward from the upper side of the band according to the rotation of the rotary lever, and the band winding shaft of the rotary lever has the shape of a cam. Then, when passing through the band insertion hole with the turning lever opened, an insertion hole slightly wider than the thickness of the band is installed toward the cam-shaped tip so that the band turns in an acute angle in the insertion direction, In addition, the band is fixed and the winding along the cam shape is urged according to the rotation of the rotation lever. After the cam shape tip passes the bottom surface of the fastener body, the rotation lever is pulled down by the band due to the cam shape and the inclination of the body bearing. direction It is characterized in that it is configured to hold the band in a positional relationship that opposes the return of the lever by lowering, and the shape is simple and easy to manufacture, and an excessive force is required from temporary tightening to closing the rotating lever to the main body. The band fastener is operated without being required, and is not easily released even when the band is pulled with a large force.

バンド挿通孔間隙は仮止めの際の引張り力と戻り力の関係に影響しとても重要であり、通常平行な間隔で良いが、挿入側を排出側より若干広く扇状に開口することで締付力を低減でき、引張り易く戻り難いようなバランスを保て使い易くなる場合もある。   The gap between the band insertion holes is very important because it affects the relationship between the pulling force and return force at the time of temporary fixing, and usually a parallel interval may be used, but the clamping force can be increased by opening the insertion side in a fan shape slightly wider than the discharge side. In some cases, it is easy to use while maintaining a balance that is easy to pull and difficult to return.

回動レバーカム状巻込み軸先端部は鋭角になっており、バンドの固定がなされる箇所であるので滑りの止めをより強力にする目的で凸凹形状にするのも得策である。   The tip of the rotating lever cam-shaped winding shaft has an acute angle, and since it is a place where the band is fixed, it is also a good idea to make it uneven so as to make the slip prevention stronger.

このバンド締付け具を用いると伸びのほとんど無いポリエステル製のバンドやステンレスバンド等の締付に際しても、仮止めも行え、約半回転の簡単な動作で締付と閉止ができ、締付け時に十分なバンドの張力を保持したままで、バンド引張り強度と同等の引張り強度を実現可能である。   With this band tightening tool, even when tightening a polyester band or stainless steel band that hardly stretches, it can be temporarily fixed, and it can be tightened and closed with a simple movement of about half a turn. It is possible to achieve a tensile strength equivalent to the band tensile strength while maintaining the above tension.

以下に本発明の一実施形態について述べる。   An embodiment of the present invention will be described below.

本実施形態に係る締付具の実施例として、軟質プラスチック製の成形品として作製し、締付具本体1と回動レバー2を組み合わせ開いた状態を図1に示す。実施例としてバンドはポリエステルバンドを用いバンド21の片方を締付具本体係止孔9aから9bに取り付け係止し、もう一方のバンド端を巻掛ける相手22を巻回した後、バンド挿通孔4に通し仮止めの状態にある断面図を図2、回動レバーの回転に伴い挿入されたバンドの固定がカム状先端(中)3bで強まり始まる断面図を図3、カム状先端3が締付具本体底面に当り回動レバー回転軸5が最上死点となる断面図を図4、回動レバーが完全に回転し、回動レバー先端係合爪6が締付具本体係合爪受け8と係合、閉止した状態の断面図を図5に示す。   As an example of the fastener according to the present embodiment, a state in which the product is produced as a molded product made of soft plastic and the fastener body 1 and the rotation lever 2 are combined and opened is shown in FIG. As an example, a polyester band is used as a band, one side of the band 21 is attached and locked to the fastener body locking holes 9a to 9b, and the band 22 is wound around the other band end. Fig. 2 is a cross-sectional view in a state of being temporarily fixed through, Fig. 3 is a cross-sectional view in which the fixation of the band inserted along with the rotation of the rotation lever starts to strengthen at the cam-shaped tip (medium) 3b, and the cam-shaped tip 3 is tightened. FIG. 4 is a cross-sectional view in which the rotary lever rotating shaft 5 hits the bottom surface of the tool body and the top dead center is at the top dead center. FIG. 5 shows a cross-sectional view of the state engaged with 8 and closed.

締付具本体1はバンド係止用の2個の係止孔9a、9bを底面に有し、底面より起立した左右の側面で構成され、係止孔9はバンドを装着し易いようにバンド厚さより十分広いの間隙を有し、バンドが引っかかり易いように波状の凹凸を設けてある。両側面には先端に回動レバー係合爪を受ける係合爪受け8と中央部分に回動レバーの回転軸を受け、回動レバー軸が上下と本体先端下部に摺動可能な形状の軸受け7が設けられている。
回動レバーは左右の軸の間に、カム形状のバンド巻込み軸10を設け、バンド厚さが0.5mmの場合0.8mmの先端間隙とした挿通孔4を中央部分からをカム形状先端へ向かって設けられている。回動レバー先端付近左右には、本体への固定の為の突出した係合爪6が設けてあり、さらに閉止状態からの解除の目的でドライバーを挿入できるように先端の左右が切り欠いてある14。
The fastener body 1 has two locking holes 9a and 9b for locking the band on the bottom surface, and is composed of left and right side surfaces that stand up from the bottom surface. The locking hole 9 is a band so that the band can be easily attached. The gap is sufficiently wider than the thickness, and wavy irregularities are provided so that the band is easily caught. An engaging claw receiver 8 that receives a rotating lever engaging claw at the tip on both sides and a rotating shaft of the rotating lever at the center, and a bearing that has a shape in which the rotating lever shaft can slide up and down and at the lower end of the main body 7 is provided.
The rotating lever is provided with a cam-shaped band winding shaft 10 between the left and right shafts, and when the band thickness is 0.5 mm, the insertion hole 4 having a tip clearance of 0.8 mm extends from the center portion to the cam-shaped tip. It is provided towards. Protruding engagement claws 6 for fixing to the main body are provided at the left and right in the vicinity of the tip of the rotating lever, and the left and right of the tip are notched so that a driver can be inserted for the purpose of releasing from the closed state. 14.

回動レバーの本体への取り付けは回動レバー回転軸に設けられた軸部きり欠き11を、締付具本体軸受け上部の本体側板上辺内側に設けられた、軸受けきり欠き12に押し込むことで樹脂製の本体の弾性により、側板が開く事を利用して取り付けられ、取り付けられた回動レバーは回転可能で、上下、前下方向へ可動に取り付けられる。   The rotating lever is attached to the main body by pushing the shaft notch 11 provided on the rotating lever rotation shaft into the bearing notch 12 provided on the inner side of the upper side of the main body side plate at the upper part of the fastener main body bearing. Due to the elasticity of the main body, it is attached by utilizing the opening of the side plate, and the attached rotation lever is rotatable and is movably attached in the vertical and forward / downward directions.

上記構成でセットしたバンド締付具を用いて、電柱等に防護板等をバンドで固定する場合には、回動レバーを取り付けられたバンド締付具の本体に予めバンドを固定しておく。すなわち固定外周長より長めにバンドを切断しておき、その片方をバンド締付具のレバーが開いた開成状態で、締付具本体後方より本体底面とレバーバンド巻込み軸10との間へ挿入し、前方のバンド係止孔9aへ通し本体底下へ排出後、後方へ折返しバンド係止孔9bから本体底面上部へ通し排出し、さらに後方へ伸張した位置で固定しておく。この状態でバンドの本体への片方の固定は完了する。   When using a band fastener set with the above-described configuration and fixing a protective plate or the like to a utility pole or the like with a band, the band is previously fixed to the body of the band fastener to which the rotation lever is attached. That is, the band is cut longer than the fixed outer peripheral length, and one of the bands is inserted between the bottom surface of the fastener body and the lever band winding shaft 10 in the opened state with the lever of the band fastener open. Then, after passing through the front band locking hole 9a and discharging to the bottom of the main body, it is turned back and discharged from the band locking hole 9b to the upper part of the bottom surface of the main body, and further fixed at a position extending rearward. In this state, fixing of one side of the band to the main body is completed.

このバンド締付具へ片方を固定したバンドを用いて、電柱等に取り付ける防護板等を巻込み、図2のようにもう片方のバンド端をバンド締付具前方より本体底面とバンド巻込み軸との間へ挿入し、さらにその端をバンド挿通孔(挿入側)4aから挿入し、バンド挿通孔(排出側)4bへ排出させておく。   Using a band with one side fixed to this band clamp, a protective plate or the like to be attached to a utility pole is wound, and the other band end is inserted from the front of the band clamp to the bottom of the main body and the band winding shaft as shown in FIG. Further, the end is inserted from the band insertion hole (insertion side) 4a and discharged to the band insertion hole (discharge side) 4b.

この時点で、バンドが平状になろうとする弾性により、回動レバーには上に持ち上げられる力が働き、締付具本体の台形の軸受け形状に沿って、上死点まで持ち上がる。巻き付けられたバンドのたわみを確認して調整しバンド挿通孔より上方へ排出されたバンドをさらに引っ張り仮止めを強固にしておく。   At this point, due to the elasticity of the band becoming flat, a force to be lifted up acts on the rotating lever, and it is raised to the top dead center along the trapezoidal bearing shape of the fastener body. The bending of the wound band is confirmed and adjusted, and the band discharged upward from the band insertion hole is further pulled to temporarily tighten the temporary fixing.

手を持ち替え、回動レバーの先端を締付具本体の前方方向へ回転させると、バンド巻込み軸とバンド挿通孔が回転し、増加するバンド経路によって生じる戻りに対する抵抗を上限とした引張り抵抗値でバンドの巻込みが始まる。初期仮止めの際のバンドの緩みが大きい場合にはここで巻き取りが進むが、初期仮止めが十分になされている場合にはここで巻き取りは殆ど進んで行かない。さらに回転を進め、図3に示すようにバンド挿通孔から排出されたバンドがカム状先端(中)3bに押さえ込まれ、排出経路が鋭角になり始める頃から、バンドの戻りに対する抵抗は激増し、バンドの固定が始まり以後バンドはバンド巻込み軸に巻き込まれて行く。   If you change your hand and rotate the tip of the pivoting lever toward the front of the clamp body, the band winding shaft and band insertion hole will rotate, and the tensile resistance value will be limited to the resistance to return caused by the increasing band path. Then the band starts to roll. If the band is loose at the time of initial temporary fixing, the winding proceeds here, but if the initial temporary fixing is sufficiently performed, the winding hardly proceeds here. Further rotation, as shown in FIG. 3, the band discharged from the band insertion hole is pressed into the cam-like tip (middle) 3b, and the discharge path begins to become an acute angle, the resistance to the return of the band increases drastically, After fixing the band, the band is wound around the band winding shaft.

さらに回転を進め、図4の様にカム状先端(外)3aが締付具本体底面を通過する際、回動レバーはその回転軸5が上死点となり、以後カム形状により巻き取りは増していきながら、同時にカム状の先端の傾きと、本体軸受けの傾斜に沿って、レバー回転軸は前方下部へ摺動して行く。この動作は巻込みを続けながら、バンドの張力に応じて回動レバーが前方下部へ摺動して行くことになり、バンドの張力に応じてカム状先端と締付具本体底面との挟み込みの力も増していく。   When the rotation is further advanced and the cam-like tip (outer) 3a passes the bottom surface of the fastener body as shown in FIG. 4, the rotary lever has its rotating shaft 5 at the top dead center. At the same time, the lever rotation shaft slides forward and downward along the inclination of the cam-like tip and the inclination of the main body bearing. In this operation, the winding lever slides to the front lower part according to the tension of the band while continuing the winding, and the cam-like tip and the bottom of the fastener body are clamped according to the tension of the band. Power will also increase.

最終締付に至るに従い巻込み軸回転による巻込みによって生じる張力は、回動レバーの前方下部への摺動により吸収され、下部の挟み込み力とのバランスで直線的には増大しては行かない為に、回動レバーの最終係止に強固な力は必要なく最終的には図5の様に回動レバー先端の係合爪6が本体系合爪受けと系合し、閉止状態となる。   The tension generated by the winding due to the rotation of the winding shaft as it reaches the final tightening is absorbed by the sliding of the rotating lever to the front lower part and does not increase linearly in balance with the pinching force of the lower part. Therefore, there is no need for a strong force for the final locking of the rotating lever, and finally the engaging claw 6 at the tip of the rotating lever is engaged with the main body system claw receiver as shown in FIG. .

閉止状態において、何らかの原因でバンドの引張り力が増加した場合に、カム状先端とレバー回転軸が摺動する本体軸受けの構造はレバーの戻りに対抗する位置関係となっており、戻る方向の張力はカム状先端を起そうとし、すなわち回動レバーが上昇する方向に力が働くことになり、これはバンドの引張り力に対抗しておりバンドの引っ張り力の増加がそのまま、回動レバーの回転の戻り力には働かない、つまり回動レバー先端の系合爪を開こうとする負荷もそのまま増加してはいかない。
この構造がこのバンド締付具の閉止状態保持を強固にすることになっている。
When the tension of the band increases for some reason in the closed state, the structure of the main body bearing on which the cam-shaped tip and the lever rotation shaft slide has a positional relationship that opposes the return of the lever. Tries to raise the cam-like tip, that is, a force acts in the direction in which the rotating lever rises, which counters the pulling force of the band, and the increase in the pulling force of the band remains as it is. The load that tries to open the system pawl at the tip of the rotating lever does not increase as it is.
This structure is intended to strengthen the holding of the band fastener in the closed state.

本考案は、例えば電柱の周面に、ケーブルや電線管もしくは防護板等を固定したり、広告・街路灯等の支持ブラケットを取付ける際に用いるいわゆる電柱バンド等の各種可撓性バンドを締付固定するためのバンド締付具に利用したり、金属鋼材の荷物の結束用に用いられるバンドや軽量梱包の為に利用されるバンドの締付具として利用可能である。   The present invention, for example, fastens various flexible bands such as so-called utility pole bands that are used when fixing cables, conduits, protective plates, etc. to the peripheral surface of utility poles, or when attaching support brackets for advertisements, street lights, etc. It can be used as a band fastener for fixing, a band used for bundling metal steel packages or a band fastener used for lightweight packaging.
