Description

本発明は、梱包用の結束バンドや部品を束ねる紐類を簡単に結束するためのプラスチック製の結束具に関するもので、簡単な操作で紐類を締結しながら、かつ、緩み無く結束でき、さらに、結束後の固定も簡単にできる結束具を提供するものである。The present invention relates to a plastic binding tool for easily binding a binding band for packing and a string for binding parts, and can be tied without loosening while fastening the string with a simple operation, The present invention provides a binding tool that can be easily fixed after binding.

従来は、ベルトや帯紐などの帯状の紐類に使用するバックルなどがあったが、以下の欠点があった。
（１）実用新案文献１のバックルは、本発明のような固定リブ、旋回リブ、締結リブや側面リブなどを有しているが、紐類の一端を締結し固着するための締結リブがその中央部分で開口しているので、弾力性が不足で紐類を固定する効果が少なかった。
また、旋回リブなどに係止用凸部が無いために、紐類の締結に際して紐類の戻りを防止する作用も弱かった。
（２）実用新案文献２のバックルは、本発明のような固定リブ、旋回リブ、締結リブや側面リブなどを有しているが、紐類の一端を締結し固着するための締結リブが開口していない。したがって、紐類の一端の固定は単純に固結びをするか、ビスや縫製など他の締結具を使用する必要があった。
（３）その他の一般的な結束具としては、鋸歯状の凸部を持った紐類を、鋸歯状の凸部と噛み合う受部を持った固定部で締結し固定するものがあった。この結束具は、結束力は非常に強いものの、それを解除する場合、つまり紐類を解く場合は鋸歯状の凸部を持った紐類そのものを切断する必要があった。したがって、この結束具は再利用できない欠点があった。Conventionally, there are buckles used for belt-like straps such as belts and straps, but there are the following drawbacks.
(1) The buckle of the utility model document 1 has a fixing rib, a turning rib, a fastening rib, a side rib and the like as in the present invention, and a fastening rib for fastening and fixing one end of the cords Since it was opened at the center, the elasticity was insufficient and the effect of fixing the strings was small.
Further, since there are no locking projections on the turning ribs or the like, the action of preventing the strings from returning when the strings are fastened is weak.
(2) The buckle of the utility model document 2 has a fixing rib, a turning rib, a fastening rib, a side rib and the like as in the present invention, but a fastening rib for fastening and fixing one end of the cords is opened. Not done. Accordingly, it is necessary to simply tie one end of the cords or use other fasteners such as screws or sewing.
(3) As another general binding tool, there is one in which a string having a serrated convex portion is fastened and fixed by a fixing portion having a receiving portion that meshes with the serrated convex portion. Although this binding tool has a very strong binding force, it is necessary to cut the string itself having a sawtooth-shaped convex part when releasing it, that is, when releasing the string. Therefore, this binding tool has a drawback that it cannot be reused.

The invention's effect

本発明の請求項１ないし２においては、紐類の一端を締結し固着するための締結リブがその側面部分で開口しているので、締結リブ全体の弾性で紐類を固定することができ、かつ、旋回リブなどに係止用凸部を設けて紐類と旋回リブなどとの摩擦係数を増加させ、紐類の締結に際して紐類の戻りを防止する効果がある。In claims 1 to 2 of the present invention, the fastening ribs for fastening and fixing one end of the cords are opened at the side surface portion thereof, so that the cords can be fixed by the elasticity of the whole fastening ribs, In addition, there is an effect of preventing the return of the cords when fastening the cords by increasing the friction coefficient between the cords and the pivoting ribs by providing locking convex portions on the pivot ribs.

請求項３においては、締結リブにテーパーをつけて締結リブの弾性の強化を図り、締結力をさらに強くできる効果がある。According to the third aspect of the present invention, the fastening rib is tapered to enhance the elasticity of the fastening rib, and the fastening force can be further increased.

請求項４においては、締結リブに結合される部分の側面リブを湾曲させることで、締結リブの弾性の強化を図り、締結力をさらに強くできる効果がある。According to the fourth aspect of the present invention, the side ribs of the portions coupled to the fastening ribs are curved, whereby the elasticity of the fastening ribs can be enhanced and the fastening force can be further increased.

図１は、本発明のプラスチック成形による結束具の一例を示すもので、材料のプラスチックは、弾性のあるポリプロピレンが望ましい。アクリルやＡＢＳ樹脂などの硬質プラスチックは、強度が強い利点はあるものの、割れることや折れることがあるため、製品の安全性上での問題がある。
１は締結リブで、紐類１２の終端を固定するためのものである。２は旋回リブで、紐類１２の緩みを防止するために紐類１２を旋回させるためのリブである。
３は支持リブで、紐類１２を巻き付けるためのものである。４は固定リブで、紐類１２の他端を固定するものである。５は左側面リブ、６は右側面リブで締結リブ１、旋回リブ２、支持リブ３、固定リブ４のそれぞれ一端に結合されるものである。
７は係止用凸部で、紐類１２の戻りを防止するための棒状の凸部で、紐類１２と各リブとの間の摩擦係数を高める働きをする。本図の場合は、係止用凸部７を各リブが対向する側にのみ設けた構成を示す。
８は開口空間部で、旋回リブ２と締結リブ１とで形成される形成される空間である。左側面リブ５が締結リブ１の左端に結合されないことで開口空間部８が形成される。９は空間部で、支持リブ３と左側面リブ５と右側面リブ６と固定リブ４とが結合されて形成される空間である。
図２は、図１のＡ−Ａ‘断面図で、紐類１２が締結される状態を示す。紐類１２の一端は、固定リブ４に巻き付けられて固定される。そして紐類１２の他端の終端は支持リブ３に巻き付けられ、さらに旋回リブ２を旋回して、開口空間部８の開口部から締結リブ１と旋回リブ２の間に挟みこまれる。そして、その終端を強く引き、結束具の外に引き出す。これで結束作業は完了する。結束を解除する場合は、紐類１２の終端を開口空間部８から横方向に引っ張って締結リブ１からはずした後に支持リブ３に巻き付いた紐類１２を締結時とは逆方向に引っ張ると、紐類１２は旋回リブ２を締結時とは逆に旋回しながら解かれてゆく。
紐類１２は、固定リブ４や旋回リブ２や締結リブ１に設けられた係止用凸部７に当接して摩擦係数が増大することで、締結される際の紐類１２の戻りを防止することができる。
ただ、摩擦係数が大きすぎると紐類１２の解除時に支障をきたすので、必要以上に旋回リブ２と支持リブ３の間隔を狭くする必要はない。FIG. 1 shows an example of a binder by plastic molding according to the present invention, and the material plastic is preferably elastic polypropylene. Hard plastics such as acrylic and ABS resins have the advantage of high strength, but they may be broken or broken, and thus there is a problem in product safety.
Reference numeral 1 denotes a fastening rib for fixing the end of the string 12. Reference numeral 2 denotes a turning rib, which is a rib for turning the string 12 in order to prevent the string 12 from loosening.
3 is a support rib for winding the string 12. Reference numeral 4 denotes a fixing rib that fixes the other end of the string 12. Reference numeral 5 denotes a left side rib, and reference numeral 6 denotes a right side rib that is coupled to one end of each of the fastening rib 1, the turning rib 2, the support rib 3, and the fixed rib 4.
Reference numeral 7 denotes a locking convex portion, which is a rod-shaped convex portion for preventing the string 12 from returning, and functions to increase the coefficient of friction between the string 12 and each rib. In the case of this figure, the structure which provided the latching convex part 7 only in the side which each rib opposes is shown.
Reference numeral 8 denotes an opening space, which is a space formed by the turning rib 2 and the fastening rib 1. Since the left side rib 5 is not coupled to the left end of the fastening rib 1, the opening space 8 is formed. Reference numeral 9 denotes a space, which is a space formed by combining the support rib 3, the left side rib 5, the right side rib 6 and the fixed rib 4.
FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG. 1 and shows a state in which the strings 12 are fastened. One end of the string 12 is wound around the fixing rib 4 and fixed. The end of the other end of the cord 12 is wound around the support rib 3, and further swivels around the turning rib 2, and is sandwiched between the fastening rib 1 and the turning rib 2 from the opening of the opening space 8. Then, the end is pulled strongly and pulled out of the binding tool. This completes the binding process. When releasing the binding, pulling the cord 12 wound around the support rib 3 after pulling the end of the cord 12 laterally from the opening space 8 and removing it from the fastening rib 1 in the direction opposite to the fastening time, The strings 12 are unwound while turning in the direction opposite to that when the turning rib 2 is fastened.
The cords 12 come into contact with the locking projections 7 provided on the fixed rib 4, the turning rib 2 and the fastening rib 1 to increase the friction coefficient, thereby preventing the cords 12 from returning when fastened. can do.
However, if the coefficient of friction is too large, it will hinder the string 12 from being released, so there is no need to make the gap between the turning rib 2 and the supporting rib 3 unnecessarily narrow.

図３は、本発明のプラスチック成形による結束具の他の一例を示すもので、係止用凸部７を各リブが対向する側に設けるだけでなく、それを各リブの対向しない側、つまり、各リブの外側にも設けたものである。
図４は、図３のＢ−Ｂ’断面図を示すものである。本図では、旋回リブ２と支持リブ３の各リブに４本の係止用凸部７が形成されている。これによって、各リブと紐類１２の摩擦係数はさらに増大する。図において、係止用凸部７は棒状の細長い凸部になっているが、通常のビニール紐などの細いタイプの紐類に有効である。紐類１２の形状によっては、複数の単なる突起を列状に配置する構成でも良い。帯紐やベルト状の紐類１２においては、各リブへの当接面積が大きくなるので、図示はしないが、複数の突起の列で構成される係止用凸部７でも摩擦係数を増大する効果はある。FIG. 3 shows another example of a binding tool by plastic molding according to the present invention. In addition to providing the projection 7 for locking on the side where each rib faces, it is arranged on the side where each rib does not face, that is, Also provided on the outside of each rib.
FIG. 4 is a sectional view taken along the line BB ′ of FIG. In this figure, four locking projections 7 are formed on each of the turning rib 2 and the supporting rib 3. Thereby, the friction coefficient of each rib and the string 12 further increases. In the figure, the locking convex portion 7 is a rod-like long and narrow convex portion, but is effective for a thin type string such as a normal vinyl string. Depending on the shape of the strings 12, a configuration in which a plurality of simple protrusions are arranged in a line may be used. In the straps and belt-like cords 12, the contact area with each rib is increased, so although not shown, the locking convex portion 7 composed of a plurality of protrusions also increases the friction coefficient. There is an effect.

図５は、図１の結束具を対称にして結合したもので、紐類１２の両端が自由端である場合の結束具である。通常は、紐類１２の一端は結束具の固定リブ４に固結びで固定され、他端は自由端として締結調整をした後に固定される。本図のように、紐類１２の両端が自由端である場合は紐類１２の締結調整や締結解除をどちらの自由端でも行なえるので取り扱いが便利になる。固定リブ４は、結束具の中心に位置し、他の各リブは固定リブ４から２本ずつ対称に配置される。本図においては、開口空間部８の位置がそれぞれ反対方向になっているが、同一方向に配置しても良い。それぞれの締結リブ１で紐類１２を引っ張り合う形になるので、力学的には開口空間部８の位置がそれぞれ反対方向にあったほうが均等に引っ張りあえる。本図の場合は、係止用凸部７を各リブが対向する側にのみ設けた構成を示す。FIG. 5 is a binding tool in which the binding tool of FIG. 1 is coupled symmetrically, and both ends of the cords 12 are free ends. Usually, one end of the string 12 is fixed to the fixing rib 4 of the tying member by tying, and the other end is fixed after fastening adjustment as a free end. As shown in this figure, when both ends of the cord 12 are free ends, the fastening adjustment and release of the cord 12 can be performed at either free end, so that handling becomes convenient. The fixing rib 4 is located at the center of the binding tool, and the other ribs are arranged symmetrically by two from the fixing rib 4. In this figure, the positions of the opening spaces 8 are in opposite directions, but they may be arranged in the same direction. Since the strings 12 are pulled by the respective fastening ribs 1, they can be pulled evenly when the positions of the opening spaces 8 are in opposite directions. In the case of this figure, the structure which provided the convex part 7 for a latch only in the side which each rib opposes is shown.

図６は、図５の結束具に、旋回リブ２と支持リブ３の各リブに４本の係止用凸部７を形成したものである。作用効果は、図３と同様である。FIG. 6 shows the binding tool of FIG. 5 in which four locking projections 7 are formed on each of the turning rib 2 and the supporting rib 3. The effect is the same as that of FIG.

図７は、締結リブ１にテーパーをつけたもので、紐類１２の締結力を増強するものである。右側面リブ６と締結リブ１の結合部分で急激にテーパーをつけるテーパー部１０を締結リブ１につける。開口空間部８側にいくにつれて締結リブ１は旋回リブ２と平行になる。テーパー部１０の作用により、締結リブ１の締結力は強化され、紐類の引っ張り力による締結リブ１の開きも防止できる。支持リブ３の係止用凸部７は、本図の場合３本にして、支持リブ３と固定リブ４が対向する側、つまり、支持リブ３の底面には係止用凸部７を設けていない。この理由は以下の通りである。
１）支持リブ３においては紐類１２が支持リブ３に巻き付くような形で紐類１２の両端が引っ張られるので、支持リブ３の底面に引っ張り力の負荷が最も多くかかる。
２）このために、底面での摩擦係数が大きくなると紐類１２の擦れによる切断が生じる可能性がある。
３）さらに、締結時の締結調整の際に紐類１２の摺動を阻害して調整がやりにくくなる可能性もある。
４）上記１）から３）の事態を防止するために、支持リブ３の底面での摩擦係数を最小限にするためのものである。FIG. 7 is a view in which the fastening rib 1 is tapered to enhance the fastening force of the strings 12. A taper portion 10 that abruptly tapers at a joint portion of the right side rib 6 and the fastening rib 1 is attached to the fastening rib 1. The fastening rib 1 becomes parallel to the turning rib 2 as it goes to the opening space 8 side. The fastening force of the fastening rib 1 is strengthened by the action of the taper portion 10, and the fastening rib 1 can be prevented from opening due to the pulling force of the strings. In the figure, the number of the protrusions 7 for locking the support ribs 3 is three, and the protrusions 7 for locking are provided on the side where the support ribs 3 and the fixing ribs 4 face each other, that is, on the bottom surface of the support ribs 3. Not. The reason is as follows.
1) Since both ends of the string 12 are pulled in such a manner that the string 12 wraps around the support rib 3 in the support rib 3, the load of the tensile force is most applied to the bottom surface of the support rib 3.
2) For this reason, when the coefficient of friction at the bottom surface increases, the cords 12 may be cut due to rubbing.
3) Furthermore, there is a possibility that the adjustment of the string 12 may be hindered by making the adjustment of the string 12 difficult to adjust.
4) In order to prevent the situations 1) to 3), the friction coefficient at the bottom surface of the support rib 3 is minimized.

図８は、締結リブ１にテーパーをつけたもので、紐類１２の締結力を増強するものである。図７との相違点は、右側面リブ６と締結リブ１の結合部分で急激にテーパーをつけるのでは無く、締結リブ１全体にテーパーをつけることである。テーパー部１０から徐々に締結リブ１にもテーパーがつけられ、開口空間部８側にいくにつれて締結リブ１全体が旋回リブ２側に傾斜してゆく構造になっている。この構造で、締結リブ１の締結力はさらに強化され、紐類の引っ張り力による締結リブ１の開きも防止できる。FIG. 8 is a view in which the fastening rib 1 is tapered, and the fastening force of the strings 12 is increased. The difference from FIG. 7 is that the entire fastening rib 1 is tapered rather than abruptly tapering at the joint between the right side rib 6 and the fastening rib 1. The fastening rib 1 is gradually tapered from the tapered portion 10, and the entire fastening rib 1 is inclined toward the revolving rib 2 as it goes to the opening space 8 side. With this structure, the fastening force of the fastening rib 1 is further strengthened, and the opening of the fastening rib 1 due to the pulling force of the strings can be prevented.

図９は、右側面リブ６に湾曲部１１を設けたもので、湾曲構造で締結リブ１に結合されるので、締結リブ１の弾性とともに湾曲部１１での弾性があいまって作用する。したがって、非常にバネ性の高い締結リブ１となり、締結時の紐類１２の締結や解除時の作業が容易になる。図１０は、支持リブ３と固定リブ４と左側面リブ５と右側面リブ６とで形成される空間部９を台形状にしたものである。固定リブ４には、紐類１２を固結びなどで固定する場合が多く、紐類１２が固定される部分の空間は狭い方が紐類１２の横方向にずれるのを防止できる。紐類１２がベルト状の幅広の場合は、台形の空間部９の一辺はベルと幅より若干広めの幅にする。ビニール紐などのように細い紐類１２の場合は、その一辺はかなり狭くても良く、三角形に近い台形にしても良い。また、本図では、固定リブ４の側面にも係止用凸部７を設けている。この理由は、固定した紐類１２が緩みにくくする緩衝材として配置したものである。紐類１２を締め上げる場合にも効いてくる。In FIG. 9, the right-side rib 6 is provided with a curved portion 11 and is coupled to the fastening rib 1 with a curved structure, so that the elasticity at the curved portion 11 acts together with the elasticity of the fastening rib 1. Therefore, it becomes the fastening rib 1 with very high spring property, and the operation | work at the time of fastening of the string 12 at the time of fastening and cancellation | release is easy. FIG. 10 shows a trapezoidal space 9 formed by the support rib 3, the fixing rib 4, the left side rib 5, and the right side rib 6. In many cases, the string 12 is fixed to the fixing rib 4 by tying or the like, and the space where the string 12 is fixed can be prevented from being shifted in the lateral direction of the string 12. When the cords 12 are belt-like wide, one side of the trapezoidal space 9 is slightly wider than the bell and the width. In the case of a thin string 12 such as a vinyl string, one side of the string 12 may be quite narrow or a trapezoid close to a triangle. Further, in this drawing, the locking projection 7 is also provided on the side surface of the fixing rib 4. This is because the fixed string 12 is arranged as a cushioning material that makes it difficult to loosen. This is also effective when the strings 12 are tightened.

図１１は、図９の結束具を対称にして結合したもので、紐類１２の両端が自由端である場合の結束具である。通常は、紐類１２の一端は結束具の固定リブ４に固結びで固定され、他端は自由端として締結調整をした後に固定される。本図のように、紐類１２の両端が自由端である場合は紐類１２の締結調整や締結解除をどちらの自由端でも行なえるので取り扱いが便利になる。固定リブ４は、結束具の中心に位置し、他の各リブは固定リブ４から２本ずつ対称に配置される。本図においては、開口空間部８と湾曲部１１の位置がそれぞれ反対方向になっているが、同一方向に配置しても良い。それぞれの締結リブ１で紐類１２を引っ張り合う形になるので、力学的には開口空間部８と湾曲部１１の位置がそれぞれ反対方向にあったほうが均等に引っ張りあえる。FIG. 11 is a binding tool in which the binding tool of FIG. 9 is coupled symmetrically, and both ends of the strings 12 are free ends. Usually, one end of the string 12 is fixed to the fixing rib 4 of the tying member by tying, and the other end is fixed after fastening adjustment as a free end. As shown in this figure, when both ends of the cord 12 are free ends, the fastening adjustment and release of the cord 12 can be performed at either free end, so that handling becomes convenient. The fixing rib 4 is located at the center of the binding tool, and the other ribs are arranged symmetrically by two from the fixing rib 4. In this figure, the positions of the opening space 8 and the bending portion 11 are opposite directions, but they may be arranged in the same direction. Since the strings 12 are pulled by the respective fastening ribs 1, the positions of the opening space 8 and the curved portion 11 are mechanically pulled evenly in the opposite directions.

図１２は、締結リブ１にテーパー部１０を設けず、かつ、右側面リブ６に湾曲部１１を設けない結束具を示すもので、締結リブ１全体が旋回リブ２の方へ傾斜して開口空間部８が狭くなる構成にしている。テーパー部１０と湾曲部１１を廃止することで、締結リブ１の強度が上がるようにしたものである。弾性をより効かすために、締結リブ１と右側面リブ６との結合部の内面をえぐった構造にしている。安価に、かつ、成形ショット数を上げるには、この簡単な構造が最適である。FIG. 12 shows a binding tool in which the taper portion 10 is not provided on the fastening rib 1 and the curved portion 11 is not provided on the right side rib 6. The space 8 is narrowed. The strength of the fastening rib 1 is increased by eliminating the tapered portion 10 and the curved portion 11. In order to make the elasticity more effective, the inner surface of the coupling portion between the fastening rib 1 and the right side rib 6 is made to be hollow. This simple structure is optimal for reducing the number of molding shots at low cost.
