Description

本発明は、ベースと、そのベースに開閉可能に設けた操作レバーとを有し、その操作レバーをベースに対し閉じることにより帯状バンドを締付けて当該帯状バンドを対象物へ巻付けるバンド締付け具であって、特に、伸びのほとんど無いポリエステル製やステンレス製のバンドを電柱等の支柱へ取り付けたり、荷造り等に使用する際に用いるバンド締付け具に関する。 The present invention is a band fastening tool that has a base and an operating lever that can be opened and closed on the base, and closes the operating lever with respect to the base to fasten the belt-like band and wind the belt-like band around an object. In particular, the present invention relates to a band fastening tool used when attaching a band made of polyester or stainless steel, which hardly stretches, to a support pole such as a utility pole or packing.

最近、例えば電柱の周面に、ケーブルや電線管もしくは表示板等を固定したり、広告・街路灯等の支持ブラケットを取付けるため、伸びのほとんど無いポリエステル製やステンレス製のバンドが使用されている。かかるバンドの締付け具として、ベースにバンド締付け用の操作レバーを回転可能に取付け、その操作レバーのバンド巻込み軸にバンド挿通孔を形成し、ベースに一端を折返し固定したバンドの他端を、ベースに対して操作レバーを開いた状態で、バンド挿通孔に通して、操作レバーをベース側に回転させ閉じることによってバンドを巻込み、締付けるように構成したバンド締付け具が各種提案されている（例えば、特許文献１，２参照。）。 Recently, for example, a band made of polyester or stainless steel that hardly stretches has been used to fix cables, conduits, display boards, etc. to the peripheral surface of utility poles, or to attach support brackets such as advertisements and street lights. . As a band fastening tool, an operating lever for tightening the band is rotatably attached to the base, a band insertion hole is formed in the band winding shaft of the operating lever, and the other end of the band which is fixed by folding one end back to the base, Various types of band fasteners configured to wind and tighten the band by rotating the operation lever toward the base side and closing it through the band insertion hole with the operation lever opened with respect to the base have been proposed ( For example, see Patent Documents 1 and 2.)

しかし、上述の特許文献１のバンド締付け具では、その図２に示すように、操作レバーのバンド巻取り軸に形成したバンド貫通孔は、電柱等の相手部材の外周面と平行でなく、その外周面に対し起立した方向を向いているため、帯状バンドを貫通孔の入口に向かって屈曲させた上でバンド貫通孔に通す必要があり、帯状バンドの締め付け作業性が悪いという問題があった。 However, in the band fastening tool of Patent Document 1 described above, as shown in FIG. 2, the band through-hole formed in the band winding shaft of the operation lever is not parallel to the outer peripheral surface of the mating member such as the utility pole, Since it faces the direction standing up with respect to the outer peripheral surface, it is necessary to bend the band-shaped band toward the inlet of the through-hole and then pass through the band through-hole, and there is a problem that the workability of tightening the band-shaped band is poor .

また、特許文献１のバンド締付け具では、バンド巻取り軸のバンド貫通孔に通した帯状バンドを仮止めするためには、その〔００１５〕に記載されているようにバンド貫通孔から排出された帯状バンドを手で引っ張る必要があり、この点でも帯状バンドの締め付け作業性が悪かった。 In addition, in the band fastening tool of Patent Document 1, in order to temporarily fix the band-shaped band that has passed through the band through-hole of the band winding shaft, the band is discharged from the band through-hole as described in [0015]. It was necessary to pull the band-shaped band by hand, and the band-band banding workability was also poor in this respect.

また、上述の特許文献２のバンド締付け具では、締付具本体に設けた帯状バンドの収容溝の一部に溝幅を帯状バンドのバンド幅よりも狭くした箇所を設けておき、操作レバーのバンド巻取り軸に形成したバンド貫通孔に帯状バンドを通した後、収容溝におけるバンド幅の狭い箇所に帯状バンドを押し込んで撓ませることで帯状バンドを締付具本体に仮留めすることができるが、収容溝へバンドを押し込む作業の分だけ、帯状バンドの締め付け作業性が悪いという問題があった。 Moreover, in the band fastening tool of the above-mentioned Patent Document 2, a part where the groove width is narrower than the band width of the belt-like band is provided in a part of the belt-like band housing groove provided in the fastener body. After passing the band-like band through the band through-hole formed in the band winding shaft, the band-like band can be temporarily fastened to the clamp body by pushing and bending the band-like band into a narrow band width in the receiving groove. However, there is a problem that the workability of tightening the band-shaped band is poor by the work of pushing the band into the receiving groove.

そこで、本発明は、このような課題を解決するためになされたもので、帯状バンドの締め付け作業性を向上させることができるバンド締付け具を提供すること目的とする。 Therefore, the present invention has been made to solve such a problem, and an object of the present invention is to provide a band fastener that can improve the workability of tightening the band-shaped band.

So as to be along the utility pole 3 etc. In the present invention, providing the tongue piece 11d at the tip of the operation lever 11 is optional and may be omitted.

＜ベース１２の構成＞
ベース１２は、図６〜図１０等に示すように、基部側には操作レバー１１の回動軸部１１ｂ，１１ｂを回動可能に支持する操作レバー支持部１２ａ，１２ａと、操作レバー１１のバンド巻取軸１１ａの外周面である第１外周面１１ａ２および第２外周面１１ａ３に対向し、第１外周面１１ａ２および第２外周面１１ａ３との間に帯状バンド２が通る隙間を形成するバンド挿通用隙間形成面１２ｂを形成する一方、先端部側には操作レバー１１の係止部１１ｃ，１１ｃそれぞれが係止する被係止部１２ｃ，１２ｃと、バンド連結孔１２ｄとを有する。 <Configuration of base 12>
As shown in FIGS. 6 to 10 and the like, the base 12 has operation lever support portions 12 a and 12 a for rotatably supporting the rotation shaft portions 11 b and 11 b of the operation lever 11 on the base side, and the operation lever 11. A band that faces the first outer peripheral surface 11a2 and the second outer peripheral surface 11a3, which are outer peripheral surfaces of the band winding shaft 11a, and forms a gap through which the band-like band 2 passes between the first outer peripheral surface 11a2 and the second outer peripheral surface 11a3. While forming the insertion gap forming surface 12b, the front end portion has locked portions 12c and 12c to which the locking portions 11c and 11c of the operation lever 11 are locked, and a band connecting hole 12d.

操作レバー支持部１２ａ，１２ａは、当該ベース部１２の基部両側から後方側壁１２ａ１，１２ａ１を立設して設けられており、その後方側壁１２ａ１，１２ａ１に、操作レバー１１の両側から突出した回動軸部１１ｂ、１２ｂが挿入される軸受け孔１２ａ２，１２ａ２を設けて構成されている。 The operation lever support portions 12a and 12a are provided with rear side walls 12a1 and 12a1 provided upright from both sides of the base portion of the base portion 12, and the rear side walls 12a1 and 12a1 are pivoted to protrude from both sides of the operation lever 11. Bearing holes 12a2 and 12a2 into which the shaft portions 11b and 12b are inserted are provided.

バンド挿通用隙間形成面１２ｂは、操作レバー１１のバンド巻取軸１１ａの外周面である第１外周面１１ａ２および第２外周面１１ａ３に対向し、第１外周面１１ａ２および第２外周面１１ａ３との間に帯状バンド２が通る隙間を形成する。 The band insertion clearance forming surface 12b faces the first outer peripheral surface 11a2 and the second outer peripheral surface 11a3, which are the outer peripheral surfaces of the band winding shaft 11a of the operation lever 11, and the first outer peripheral surface 11a2 and the second outer peripheral surface 11a3. A gap through which the belt-like band 2 passes is formed.

そのため、バンド挿通用隙間形成面１２ｂの横幅Ｗ（図７（ａ）参照。）は、帯状バンド２の横幅以上としている。尚、実施形態１においては、バンド挿通用隙間形成面１２ｂを湾曲面としたが、第１外周面１１ａ２および第２外周面１１ａ３との間に帯状バンド２が通る隙間を形成すれば他の形状でも良い。 Therefore, the lateral width W (see FIG. 7A) of the band insertion gap forming surface 12b is set to be equal to or larger than the lateral width of the band-like band 2. In the first embodiment, the band insertion gap forming surface 12b is a curved surface. However, if a gap is formed between the first outer peripheral surface 11a2 and the second outer peripheral surface 11a3, the band-like band 2 can pass through other shapes. But it ’s okay.

ここで、バンド挿通用隙間形成面１２ｂの先端部側には、帯状バンド２をバンド巻取軸１１ａのバンド貫通孔１１ａ１のバンド入口１１ａ１１からバンド出口１１ａ１２へ通した後、操作レバー１１を閉める方向に回動させると、バンド巻取軸１１ａの第２外周面１１ａ３におけるバンド出口１１ａ１３側の角部１１ａ３１との間で、バンド巻取軸１１ａのバンド貫通孔１１ａ１のバンド出口１１ａ１２側から出た帯状バンド２の方向を変えて挟持するバンド挟持用段部１２ｂ１を設けている。 Here, on the distal end side of the band insertion gap forming surface 12b, the band 2 is passed from the band inlet 11a11 to the band outlet 11a12 of the band through hole 11a1 of the band winding shaft 11a, and then the operation lever 11 is closed. When it is rotated to the band outlet 11a13 of the band take-up shaft 11a, the band exit from the band outlet 11a12 side of the band through-hole 11a1 between the second outer peripheral surface 11a3 of the band take-up shaft 11a and the corner 11a31 on the band outlet 11a13 side. A band clamping step 12b1 is provided for changing the direction of the band 2 for clamping.

また、バンド挿通用隙間形成面１２ｂの基部（後端部）側には、操作レバー１１がベース１２に対し最大限開いて全開状態になる際、操作レバー１１のバンド巻取軸１１ａのレバー側凸部１１ａ４に当接した際、弾性変形することにより係合してその全開状態を保持するベース側凸部１２ｂ２を設けている。 Further, on the base (rear end) side of the band insertion gap forming surface 12b, when the operating lever 11 is fully opened with respect to the base 12, the lever side of the band winding shaft 11a of the operating lever 11 is opened. A base-side convex portion 12b2 is provided that engages by elastic deformation when it abuts on the convex portion 11a4 and maintains its fully open state.

バンド挟持用段部１２ｂ１は、図７（ａ）に示すようにバンド挿通用隙間形成面１２ｂの幅Ｗとほぼ同じ幅で、かつ、図９（ａ），（ｂ）に示すようにベース側凸部１２ｂ２の高さよりも高く形成している。 The band clamping step 12b1 is substantially the same width as the width W of the band insertion gap forming surface 12b as shown in FIG. 7 (a), and the base side as shown in FIGS. 9 (a) and 9 (b). It is formed higher than the height of the convex portion 12b2.

ベース側凸部１２ｂ２は、図７（ａ），（ｂ）に示すようにその両側にスリット１２ｂ２１，１２ｂ２１を設けて、バンド挿通用隙間形成面１２ｂの幅Ｗより短い幅として操作レバー１１のバンド巻取軸１１ａのレバー側凸部１１ａ４に弾接して係合するように構成している。 As shown in FIGS. 7 (a) and 7 (b), the base-side convex portion 12b2 is provided with slits 12b21 and 12b21 on both sides thereof, and has a width shorter than the width W of the band insertion gap forming surface 12b. It is configured to elastically contact and engage with the lever-side convex portion 11a4 of the winding shaft 11a.

ここで、実施形態１のバンド締付け具１のベース側凸部１２ｂ２では、図９（ｂ）や後述する図１１（ｂ）〜図１３（ｂ）に示すように境界部１２ｂ２２を中心（境界）としてその前後にそれぞれロック用係合面１２ｂ２３と、仮止め用係合面１２ｂ２４とを有する。 Here, in the base side convex portion 12b2 of the band fastener 1 of Embodiment 1, the boundary portion 12b22 is centered (boundary) as shown in FIG. 9B and FIGS. 11B to 13B described later. As shown in the figure, the front and rear of each have a locking engagement surface 12b23 and a temporary fixing engagement surface 12b24.

被係止部１２ｃ，１２ｃは、当該ベース部１２の先端部両側から前方側壁１２ｃ１，１２ｃ１を立設して設けられており、その前方側壁１２ｃ１，１２ｃ１に、操作レバー１１の係止部１１ｃ，１１ｃの断面形状と同様の断面形状でその係止部１１ｃ，１１ｃが嵌合等して係止する被係止孔１２ｃ２，１２ｃ２を設け構成されている。 The locked portions 12c and 12c are provided with front side walls 12c1 and 12c1 provided upright from both sides of the tip of the base portion 12, and the locking portions 11c and 12c1 of the operation lever 11 are provided on the front side walls 12c1 and 12c1, respectively. Locked holes 12c2 and 12c2 are formed to have the same cross-sectional shape as that of 11c and to which the locking portions 11c and 11c are engaged and locked.

バンド連結孔１２ｄは、バンド巻取軸１１ａのバンド貫通孔１１ａ１に挿入される帯状バンド２の一端（先端部）とは反対側である帯状バンド２の他端（後端部）を連結するための孔である。 The band connecting hole 12d connects the other end (rear end) of the band 2 opposite to one end (front end) of the band 2 inserted into the band through hole 11a1 of the band winding shaft 11a. It is a hole.

＜実施形態１のバンド締付け具１の作用＞
次に、以上のように構成された実施形態１のバンド締付け具１の作用について、図面を元に説明する。 <Operation of Band Fastener 1 of Embodiment 1>
Next, the operation of the band fastener 1 of the first embodiment configured as described above will be described based on the drawings.

まず、帯状バンド２の他端（後端部）を実施形態１のバンド締付け具１を構成するベース１２のバンド連結孔１２ｄに連結し、その帯状バンド２を電柱３の外周に巻き回した後、図１１（ａ），（ｂ）に示すように、帯状バンド２の一端（先端部）を全開状態にある操作レバー１１のバンド巻込み軸１１ａのバンド挿通孔１１ａ１のバンド入口１１ａ１１側からバンド出口１１ａ１２側へ通す。 First, after the other end (rear end portion) of the band-like band 2 is connected to the band connecting hole 12d of the base 12 constituting the band fastener 1 of Embodiment 1, the band-like band 2 is wound around the outer periphery of the utility pole 3 11 (a) and 11 (b), one end (tip portion) of the band-shaped band 2 is opened from the band inlet 11a11 side of the band insertion hole 11a1 of the band winding shaft 11a of the operating lever 11 in the fully opened state. Pass to the exit 11a12 side.

その際、実施形態１のバンド締付け具１では、図１１（ｂ）に示すように、本発明の全開状態保持機構を構成するレバー側凸部１１ａ４がベース側凸部１２ｂ２のロック用係合面１２ｂ２３に係合しており、操作レバー１１がベース１２に対し最大限開いた全開状態を保持している。 At that time, in the band fastener 1 of Embodiment 1, as shown in FIG. 11 (b), the lever side convex portion 11a4 constituting the fully opened state holding mechanism of the present invention is the locking engagement surface of the base side convex portion 12b2. 12 b 23 is engaged, and the operation lever 11 is kept fully open with respect to the base 12.

つまり、この全開状態では、作業者が操作レバー１１を掴んで一定以上の力でα方向に回動しないと、操作レバー１１がベース１２に対し回動しない。そのため、操作レバー１１が全開状態の際、操作レバー１１が勝手に回動することを防止でき、バンド巻取軸１１ａのバンド貫通孔１１ａ１への帯状バンド２の挿通作業が簡単になり、帯状バンド２の締め付け作業性を向上させることができる。 In other words, in this fully open state, the operator does not rotate with respect to the base 12 unless the operator grasps the operation lever 11 and does not rotate in the α direction with a certain force or more. Therefore, when the operation lever 11 is fully opened, the operation lever 11 can be prevented from rotating freely, and the band band 2 can be easily inserted into the band through-hole 11a1 of the band winding shaft 11a. The tightening workability of 2 can be improved.

また、操作レバー１１が全開状態保持機構により全開状態でベース１２に保持された状態では、図１１（ａ），（ｂ）に示すように、バンド巻取軸１１ａのバンド貫通孔１１ａ１は、ベース１２とほぼ平行になり、しかもバンド貫通孔１１ａ１のバンド入口１１ａ１１およびバンド出口１１ａ１２がベース１２の上面よりも高くなるように構成されているため、この点でも、バンド巻取軸１１ａのバンド貫通孔１１ａ１への帯状バンド２の挿通作業が簡単になり、帯状バンド２の締め付け作業性を向上させることができる。 When the operation lever 11 is held by the base 12 in the fully open state by the fully open state holding mechanism, as shown in FIGS. 11A and 11B, the band through-hole 11a1 of the band winding shaft 11a is 12, and the band inlet 11 a 11 and the band outlet 11 a 12 of the band through hole 11 a 1 are configured to be higher than the upper surface of the base 12. Also in this respect, the band through hole of the band winding shaft 11 a The work of inserting the band 2 into the 11a1 is simplified, and the workability of tightening the band 2 can be improved.

次に、図１１（ａ），（ｂ）に示す操作レバー１１の全開状態から操作レバー１１をα方向に若干回動させても、図１２（ａ），（ｂ）に示すようにレバー側凸部１１ａ４の先端部がベース側凸部１２ｂ２の境界部１２ｂ２２に達するまでは、レバー側凸部１１ａ４とベース側凸部１２ｂ２のロック用係合面１２ｂ２３とが弾接状態で係合し、かつ、帯状バンド２にテンション（引張力）がかかるため、操作レバー１１から手を離すと全開状態に戻る。尚、実施形態１では、レバー側凸部１１ａ４とベース側凸部１２ｂ２が係合する際、ベース側凸部１２ｂ２の方が弾性変形するように構成している。 Next, even if the operating lever 11 is slightly rotated in the α direction from the fully opened state of the operating lever 11 shown in FIGS. 11A and 11B, the lever side as shown in FIGS. Until the tip of the convex portion 11a4 reaches the boundary portion 12b22 of the base-side convex portion 12b2, the lever-side convex portion 11a4 and the locking engagement surface 12b23 of the base-side convex portion 12b2 are engaged in an elastic contact state, and Since a tension (tensile force) is applied to the belt-like band 2, when the hand is released from the operation lever 11, it returns to the fully open state. In the first embodiment, when the lever-side convex portion 11a4 and the base-side convex portion 12b2 are engaged, the base-side convex portion 12b2 is configured to be elastically deformed.

そして、図１２（ａ），（ｂ）に示すようなレバー側凸部１１ａ４の先端部がベース側凸部１２ｂ２の境界部１２ｂ２２に達した状態から、操作レバー１１をα方向にさらに回動させると、バンド巻取軸１１ａもα方向に回動するので、図１３（ａ），（ｂ）に示すように、バンド貫通孔１１ａ１のバンド出口１１ａ１２側では、帯状バンド２は少なくとも第２外周面１１ａ３の角部１１ａ３１と、バンド挟持用段部１２ｂ１の後端側の角部１２ｂ１１とに当接して曲がり、バンド巻取軸１１ａの第２外周面１１ａ３に巻付いていき、バンド挿通用隙間形成面１２ｂとバンド巻取軸１１ａとの間の隙間に入り込んでいく。 Then, the lever 11 is further rotated in the α direction from the state where the tip of the lever-side convex portion 11a4 reaches the boundary portion 12b22 of the base-side convex portion 12b2 as shown in FIGS. 12 (a) and 12 (b). Since the band take-up shaft 11a also rotates in the α direction, as shown in FIGS. 13A and 13B, at the band outlet 11a12 side of the band through hole 11a1, the band-shaped band 2 is at least the second outer peripheral surface. 11a3 corner 11a31 and the band clamping step 12b1 corner 12b11 on the rear end side of the band 11b3 are bent and wound around the second outer peripheral surface 11a3 of the band take-up shaft 11a to form a band insertion gap It enters into the gap between the surface 12b and the band take-up shaft 11a.

そのため、実施形態１のバンド締付け具１によれば、伸びのほとんど無いポリエステル製やステンレス製の帯状バンド２でも、バンド巻取軸１１ａのバンド貫通孔１１ａ１から抜けることを確実に防止しながら巻取ることができ、上述の特許文献１記載の発明のようにバンド貫通孔のバンド入口に向かって帯状バンドを屈曲させる必要がなく、バンド貫通孔から排出された帯状バンドを手で引っ張ったり、上述の特許文献２記載の発明のように収容溝に押し込む作業が不要になり、帯状バンド２の締め付け作業性を向上させることができる。 Therefore, according to the band fastener 1 of Embodiment 1, even a belt-like band 2 made of polyester or stainless steel that hardly stretches is wound while reliably preventing it from coming out of the band through-hole 11a1 of the band take-up shaft 11a. There is no need to bend the band-shaped band toward the band entrance of the band through-hole as in the invention described in Patent Document 1, and the band-shaped band discharged from the band through-hole can be pulled by hand, As in the invention described in Patent Document 2, the work of pushing into the housing groove becomes unnecessary, and the workability of tightening the belt-like band 2 can be improved.

一方、図１２（ａ），（ｂ）に示すようなレバー側凸部１１ａ４の先端部がベース側凸部１２ｂ２の境界部１２ｂ２２に達した状態から、図１３（ａ），（ｂ）に示すように操作レバー１１をα方向にさらに回動させると、レバー側凸部１１ａ４がベース側凸部１２ｂ２の境界部１２ｂ２２を乗り越えてロック用係合面１２ｂ２３に係合しなくなり、境界部１２ｂ２２を介しロック用係合面１２ｂ２３とは反対側の仮止め用係合面１２ｂ２４に係合する。 On the other hand, as shown in FIGS. 12 (a) and 12 (b), the tip of the lever-side convex portion 11a4 reaches the boundary portion 12b22 of the base-side convex portion 12b2, as shown in FIGS. 13 (a) and 13 (b). When the operating lever 11 is further rotated in the α direction as described above, the lever-side convex portion 11a4 gets over the boundary portion 12b22 of the base-side convex portion 12b2 and does not engage with the locking engagement surface 12b23, and the boundary portion 12b22 is interposed. It engages with the temporary engagement surface 12b24 opposite to the lock engagement surface 12b23.

図１３（ａ），（ｂ）に示す状態は、レバー側凸部１１ａ４がロック用係合面１２ｂ２３に係合しなくなったため、操作レバー１１が全開状態から開放されているものの、バンド巻取軸１１ａへの帯状バンド２の巻付きにより帯状バンド２にはテンション（引張力）が作用しているので、操作レバー１１にはα方向とは逆の方向へ戻ろうとする力が作用している。 In the state shown in FIGS. 13A and 13B, the lever-side convex portion 11a4 is not engaged with the locking engagement surface 12b23, so that the operating lever 11 is released from the fully open state. Since the belt-like band 2 is wound around 11a, a tension (tensile force) is acting on the belt-like band 2. Therefore, a force for returning to the direction opposite to the α direction is acting on the operating lever 11.

そのため、作業者が操作レバー１１から手を離したり、α方向に操作レバー１１を回動する力を緩めると、操作レバー１１は、帯状バンド２のテンション（引張力）によってα方向とは逆方向、すなわち全開状態へ戻ろうとする。 Therefore, when the operator releases his / her hand from the operation lever 11 or loosens the force to rotate the operation lever 11 in the α direction, the operation lever 11 is opposite to the α direction due to the tension (tensile force) of the band 2. That is, it tries to return to the fully open state.

しかし、図１３（ａ），（ｂ）に示すように、バンド巻取軸１１ａのレバー側凸部１１ａ４がベース１２のベース側凸部１２ｂ２の仮止め用係合面１２ｂ２４に当接して係合しているので、レバー側凸部１１ａ４がベース側凸部１２ｂ２の仮止め用係合面１２ｂ２４および境界部１２ｂ２２を乗り越えるような力を操作レバー１１に掛けない限り、操作レバー１１は全開状態へ戻らない。 However, as shown in FIGS. 13A and 13B, the lever-side convex portion 11a4 of the band take-up shaft 11a abuts against the temporarily fixing engaging surface 12b24 of the base-side convex portion 12b2 of the base 12 to be engaged. Therefore, unless the lever-side convex portion 11a4 gets over the operating lever 11 such that the lever-side convex portion 11a4 gets over the temporary fixing engagement surface 12b24 and the boundary portion 12b22 of the base-side convex portion 12b2, the operating lever 11 returns to the fully opened state. Absent.

つまり、図１３（ａ），（ｂ）に示す状態は、帯状バンド２のテンション（引張力）によってバンド巻取軸１１ａのレバー側凸部１１ａ４が、ベース１２のベース側凸部１２ｂ２の仮止め用係合面１２ｂ２４に当接して係合しているため、作業者が操作レバー１１から手を離しても、操作レバー１１を閉めるα方向およびその逆方向に回動せず、かつ、バンド巻取軸１１ａのバンド貫通孔１１ａ１に通した帯状バンド２が抜けない仮止め（仮留め）状態となる。 That is, in the state shown in FIGS. 13A and 13B, the lever-side convex portion 11a4 of the band winding shaft 11a is temporarily fixed to the base-side convex portion 12b2 of the base 12 by the tension (tensile force) of the band-like band 2. Therefore, even if the operator releases his / her hand from the operation lever 11, the operator does not rotate in the α direction for closing the operation lever 11 and the opposite direction, and the band winding. The belt-like band 2 passed through the band through-hole 11a1 of the spindle 11a is in a temporarily fixed (temporarily fixed) state in which it cannot be removed.

そのため、実施形態１のバンド締付け具１によれば、上述の特許文献１記載の発明のようにバンド貫通孔から排出された帯状バンドを手で引っ張ったり、上述の特許文献２記載の発明のように収容溝に押し込む作業を行わずに、作業者は、図１３（ａ），（ｂ）に示す仮止め状態において、操作レバー１１から手を放して、バンド締付け具１や帯状バンド２の位置等を簡単に調整することができ、帯状バンド２の締め付け作業性を向上させることができる。 Therefore, according to the band fastening tool 1 of the first embodiment, the band-shaped band discharged from the band through hole is pulled by hand as in the invention described in Patent Document 1 described above, or as in the invention described in Patent Document 2 described above. Without performing the operation of pushing into the housing groove, the operator releases his hand from the operation lever 11 in the temporarily fixed state shown in FIGS. 13 (a) and 13 (b) to position the band fastener 1 and the band 2 Etc. can be adjusted easily, and the tightening workability of the belt-like band 2 can be improved.

そして、図１３（ａ），（ｂ）に示す仮止め状態から操作レバー１１をさらにα方向に回動させると、バンド貫通孔１１ａ１のバンド出口１１ａ１２側から出た帯状バンド２はバンド巻取軸１１ａの第２外周面１１ａ３に巻き付いてバンド挿通用隙間形成面１２ｂとの間の隙間に入り込む一方、バンド貫通孔１１ａ１のバンド入口１１ａ１１側から延びる帯状バンド２は第１外周面１１ａ２に巻付いていく。 Then, when the operation lever 11 is further rotated in the α direction from the temporarily fixed state shown in FIGS. 13A and 13B, the belt-like band 2 coming out from the band outlet 11a12 side of the band through-hole 11a1 becomes the band winding shaft. The band-like band 2 extending from the band inlet 11a11 side of the band through hole 11a1 is wound around the first outer peripheral surface 11a2 while being wound around the second outer peripheral surface 11a3 of 11a and entering the gap between the band insertion gap forming surface 12b. Go.

操作レバー１１をさらにα方向に回動させベース１２に対し全閉状態になると、図１４（ａ），（ｂ）に示すように操作レバー１１の先端部両側の係止部１１ｃ，１１ｃがベース部１２の先端部両側に設けられた被係止部１２ｃ，１２ｃに係止する。 When the operation lever 11 is further rotated in the α direction to be fully closed with respect to the base 12, the locking portions 11c and 11c on both sides of the distal end portion of the operation lever 11 are moved to the base as shown in FIGS. 14 (a) and 14 (b). The portion 12 is locked to the locked portions 12c and 12c provided on both sides of the tip portion.

その際、バンド貫通孔１１ａ１のバンド出口１１ａ１２側から出た帯状バンド２は、バンド巻取軸１１ａの第２外周面１１ａ３に巻き付き、バンド挿通用隙間形成面１２ｂとの間の隙間のバンド入口側からバンド出口側まで入り込むことになる。 At that time, the band 2 from the band outlet 11a12 side of the band through hole 11a1 is wound around the second outer peripheral surface 11a3 of the band take-up shaft 11a, and the band entrance side of the gap between the band insertion gap forming surface 12b. It will enter from the band exit side.

その一方、バンド貫通孔１１ａ１のバンド入口１１ａ１１側から延びる帯状バンド２は、バンド巻取軸１１ａのレバー側凸部１１ａ４および第１外周面１１ａ２に巻付きながら引っ張られるので、帯状バンド２全体にテンション（引張力）が掛かり、電柱３に確実に固定できることになる。 On the other hand, the band-like band 2 extending from the band inlet 11a11 side of the band through-hole 11a1 is pulled while being wound around the lever-side convex part 11a4 and the first outer peripheral surface 11a2 of the band take-up shaft 11a. (Tensile force) is applied and can be reliably fixed to the utility pole 3.

従って、実施形態１のバンド締付け具１によれば、帯状バンド２をバンド巻取軸１１ａのバンド貫通孔１１ａ１のバンド入口１１ａ１１からバンド出口１１ａ１２へ通した後、操作レバー１１を閉める方向に回動させると、少なくともバンド巻取軸１１ａの第２外周面１１ａ３におけるバンド出口１１ａ１３側の角部１１ａ３１と、ベース１２のバンド挟持用段部１２ｂ１とでバンド巻取軸１１ａから出た帯状バンド２が当接して第２外周面１１ａ３に巻付いていくため、上述の特許文献１記載の発明のようにバンド貫通孔のバンド入口に向かって帯状バンドを屈曲させる必要がなく、バンド貫通孔１１ａ１から排出された帯状バンド２を手で引っ張ったり、上述の特許文献２記載の発明のように収容溝に押し込む作業が不要になり、帯状バンド２の締め付け作業性を向上させることができる。 Therefore, according to the band fastening tool 1 of the first embodiment, the band-shaped band 2 is passed through the band inlet 11a11 of the band through-hole 11a1 of the band winding shaft 11a from the band outlet 11a12 and then rotated in the direction to close the operation lever 11. As a result, at least the corner portion 11a31 on the band outlet 11a13 side of the second outer peripheral surface 11a3 of the band take-up shaft 11a and the band clamping step portion 12b1 of the base 12 contact the band-like band 2 coming out of the band take-up shaft 11a. Since it is wound around the second outer peripheral surface 11a3, it is not necessary to bend the band-shaped band toward the band inlet of the band through hole as in the invention described in Patent Document 1 described above, and it is discharged from the band through hole 11a1. Therefore, it is not necessary to pull the band-shaped band 2 by hand or push it into the receiving groove as in the invention described in Patent Document 2 above. It is possible to improve the fastening operation of the de-2.

特に、実施形態１のバンド締付け具１では、バンド巻取軸１１ａのレバー側凸部１１ａ４と、ベース１２のベース側凸部１２ｂ２とからなる全開状態保持機構により操作レバー１１が最大限開いた全開状態を保持するように構成したため、全開状態において操作レバー１１が回動することを防止できる。そのため、操作レバー１１への帯状バンド２の挿通作業が簡単になり、この点でも、帯状バンド２の締め付け作業性を向上させることができる。 In particular, in the band fastening tool 1 of the first embodiment, the fully opened state holding mechanism that includes the lever side convex portion 11a4 of the band winding shaft 11a and the base side convex portion 12b2 of the base 12 fully opens the operating lever 11 to the maximum extent. Since the state is maintained, the operation lever 11 can be prevented from rotating in the fully opened state. Therefore, the operation of inserting the band-shaped band 2 into the operation lever 11 is simplified, and the tightening workability of the band-shaped band 2 can be improved also in this respect.

また、実施形態１のバンド締付け具１では、全開状態保持機構を構成するレバー側凸部１１ａ４はバンド巻取軸１１ａのバンド貫通孔１１ａ１のバンド入口１１ａ１１側に設ける一方、ベース側凸部１２ｂ２はベース１２の基端側に設けたので、ベース１２に対し操作レバー１１の起立角度β（図１３（ａ）参照。）が小さい角度、すなわち操作レバー１１を少ない操作量で仮止め（仮留め）することが可能になり、この点でも帯状バンド２の締め付け作業性を向上させることができる。 Moreover, in the band clamp 1 of Embodiment 1, the lever side convex part 11a4 which comprises a fully open state holding mechanism is provided in the band inlet 11a11 side of the band through-hole 11a1 of the band winding shaft 11a, while the base side convex part 12b2 is provided. Since it is provided at the base end side of the base 12, the angle at which the operation lever 11 rises with respect to the base 12 is small (see FIG. 13A), that is, the operation lever 11 is temporarily fixed (temporarily fixed) with a small operation amount. In this respect, the tightening workability of the belt-like band 2 can be improved.

また、実施形態１のバンド締付け具１では、バンド貫通孔１１ａ１のバンド入口１１ａ１１側から延びる帯状バンド２は、第１外周面１１ａ２に巻付けられる前に、第１外周面１１ａ２よりも高さが高い全開状態保持機構を構成するレバー側凸部１１ａ４に巻付いて引っ張られるため、効率良く帯状バンド２全体により強いテンション（引張力）を簡単に掛けることができる。 In the band fastener 1 of the first embodiment, the band-like band 2 extending from the band inlet 11a11 side of the band through-hole 11a1 is higher than the first outer peripheral surface 11a2 before being wound around the first outer peripheral surface 11a2. Since it is wound and pulled around the lever-side convex portion 11a4 constituting the high fully open state holding mechanism, a strong tension (tensile force) can be easily applied to the entire belt-like band 2 efficiently.

また、実施形態１のバンド締付け具１では、全開状態保持機構により操作レバー１１が全開状態でベース１２に保持された状態で帯状バンド２をバンド巻取軸１１ａのバンド貫通孔１１ａ１へ通した後、操作レバー１１を閉めるα方向に回動して、レバー側凸部１１ａ４がベース側凸部１１ｂ２の境界部１１ｂ２２を乗り越えると、レバー側凸部１１ａ４がベース側凸部１１ｂ２のロック用係合面１１ｂ２３に係合しなくなり、ベース側凸部１２ｂ２の仮止め用係合面１２ｂ２４に係合する。そのため、上述の特許文献１記載の発明のようにバンド貫通孔１１ａ１から排出された帯状バンド２を手で引っ張ったり、上述の特許文献２記載の発明のように収容溝に押し込むことなく帯状バンド２および操作レバー１１の仮止め（仮留め）が可能になり、この点でも帯状バンド２の締め付け作業性を向上させることができる。 Further, in the band fastener 1 of the first embodiment, after the band-shaped band 2 is passed through the band through-hole 11a1 of the band winding shaft 11a in a state where the operation lever 11 is held in the base 12 in the fully opened state by the fully opened state holding mechanism. When the lever side convex portion 11a4 gets over the boundary portion 11b22 of the base side convex portion 11b2 by rotating in the α direction to close the operation lever 11, the lever side convex portion 11a4 is engaged with the locking engagement surface of the base side convex portion 11b2. No longer engages with 11b23, and engages with the temporarily fixing engaging surface 12b24 of the base-side convex portion 12b2. Therefore, the belt-like band 2 is pulled without manually pulling the belt-like band 2 discharged from the band through-hole 11a1 as in the invention described in the above-mentioned Patent Document 1 or pushing into the housing groove as in the above-described invention in Patent Document 2. In addition, the operating lever 11 can be temporarily fixed (temporarily fixed), and the tightening workability of the belt-like band 2 can be improved also in this respect.

また、実施形態１のバンド締付け具１では、操作レバー１１が全開状態保持機構により全開状態でベース１２に保持された状態では、図１１（ａ），（ｂ）等に示すように、バンド巻取軸１１ａのバンド貫通孔１１ａ１は、ほぼベース１２とほぼ平行になり、しかもバンド貫通孔１１ａ１のバンド入口１１ａ１１およびバンド出口１１ａ１２がベース１２の上面よりも高くなるので、この点でも、バンド巻取軸１１ａのバンド貫通孔１１ａ１への帯状バンド２の挿通作業が簡単になり、この点でも帯状バンド２の締め付け作業性を向上させることができる。 Further, in the band fastening tool 1 of the first embodiment, when the operation lever 11 is held by the base 12 in the fully opened state by the fully opened state holding mechanism, as shown in FIGS. The band through-hole 11a1 of the spindle 11a is substantially parallel to the base 12, and the band inlet 11a11 and the band outlet 11a12 of the band through-hole 11a1 are higher than the upper surface of the base 12. The work of inserting the belt-like band 2 into the band through-hole 11a1 of the shaft 11a is simplified, and the tightening workability of the belt-like band 2 can be improved also in this respect.

また、バンド巻取軸１１ａの第１外周面１１ａ２および第２外周面１１ａ３には、当該バンド巻取軸１１ａの軸方向に延びる凸条部と凹条部とが交互に設けられているため、帯状バンド２を巻付ける際の抵抗が増大し、滑り難くなり、この点でも帯状バンド２の締め付け作業性を向上させることができる。 In addition, since the first outer peripheral surface 11a2 and the second outer peripheral surface 11a3 of the band winding shaft 11a are alternately provided with protruding strips and concave strips extending in the axial direction of the band winding shaft 11a, The resistance at the time of winding the belt-like band 2 increases, and it becomes difficult to slip. In this respect, the tightening workability of the belt-like band 2 can be improved.

実施形態２．
次に、実施形態２のバンド締付け具１’について説明する。尚、実施形態２のバンド締付け具１’は、上述した実施形態１のバンド締付け具１とほぼ同じ構成であるため、異なる構成を中心に説明する。 Embodiment 2. FIG.
Next, the band fastener 1 ′ of the second embodiment will be described. In addition, since the band fastener 1 'of Embodiment 2 is the substantially the same structure as the band fastener 1 of Embodiment 1 mentioned above, it demonstrates centering on a different structure.

図１５（ａ），（ｂ）は、それぞれ、実施形態２のバンド締付け具１’における操作レバー１１’が全開状態にあるときの平面図、Ｅ−Ｅ線断面図、図１６（ａ），（ｂ）は、それぞれ、その全開状態にあるときの正面図、底面図、図１７（ａ），（ｂ）は、それぞれ、操作レバー１１’の正面図、底面図、図１８（ａ），（ｂ）は、それぞれ、操作レバー１１’の平面図、Ｆ−Ｆ線断面図である。 15 (a) and 15 (b) are a plan view, a cross-sectional view taken along the line EE, and FIG. 16 (a), respectively, when the operating lever 11 ′ of the band fastener 1 ′ of the second embodiment is in a fully open state. (B) is a front view and a bottom view, respectively, in the fully open state, and FIGS. 17 (a) and (b) are a front view, a bottom view, and FIG. 18 (a), FIG. (B) is a plan view of the operation lever 11 ′, and a sectional view taken along line FF, respectively.

また、図１９（ａ），（ｂ）は、それぞれ、実施形態２のバンド締付け具１’を構成するベース１２’の平面図、底面図、図２０（ａ），（ｂ）は、それぞれ、ベース１２’の正面図、背面図、図２１（ａ），（ｂ）は、それぞれ、ベース１２’の右側面図、Ｇ−Ｇ線断面図、図２２（ａ），（ｂ）は、それぞれ、ベース１２’の右側面図、Ｈ―Ｈ線断面図である。 FIGS. 19A and 19B are a plan view and a bottom view of the base 12 ′ constituting the band fastener 1 ′ of the second embodiment, respectively, and FIGS. 20A and 20B are respectively The front view, rear view, and FIGS. 21 (a) and (b) of the base 12 ′ are the right side view, the GG cross-sectional view of the base 12 ′, and FIGS. 22 (a) and (b), respectively. FIG. 6 is a right side view of the base 12 ′ and a cross-sectional view taken along the line HH.

実施形態２のバンド締付け具１’では、図１４〜図２６に示すように基本的な構造は、述した図１〜図１３に示す実施形態１のバンド締付け具１の構成とほぼ同じであるが、全開状態保持機構の構成を変更したものである。 In the band fastener 1 ′ of the second embodiment, the basic structure is almost the same as the configuration of the band fastener 1 of the first embodiment shown in FIGS. 1 to 13 as shown in FIGS. 14 to 26. However, the configuration of the fully open state holding mechanism is changed.

つまり、実施形態２のバンド締付け具１’では、図１７（ａ），（ｂ）および図１８（ｂ）に示すように操作レバー１１’のバンド巻取軸１１ａ’ではなく、操作レバー１１’のバンド巻取軸１１ａ’の外側の操作レバー１１’の基部の左右両側にそれぞれ弾性変形してベース側凸部１２ｂ２’に係合するレバー側凸部１１ａ４’を設ける。 That is, in the band fastening tool 1 ′ of the second embodiment, as shown in FIGS. 17A, 17B and 18B, the operation lever 11 ′ is not the band winding shaft 11a ′ of the operation lever 11 ′. A lever-side convex portion 11a4 ′ that is elastically deformed and engages with the base-side convex portion 12b2 ′ is provided on both the left and right sides of the base portion of the operating lever 11 ′ outside the band winding shaft 11a ′.

その一方、ベース１２’には、図１９（ａ）や図２０（ａ）,（ｂ）、図２２（ｂ）に示すように、操作レバー１１’の基部両側のレバー側凸部１１ａ４’に対向する箇所にそれぞれベース側凸部１２ｂ２’を設ける。 On the other hand, the base 12 ′ has a lever-side convex portion 11a4 ′ on both sides of the base portion of the operation lever 11 ′ as shown in FIGS. 19A, 20A, 20B, and 22B. Base-side convex portions 12b2 'are provided at the opposing locations.

そして、実施形態２のバンド締付け具１’のベース側凸部１２ｂ２’では、図２２（ｂ）〜図２５（ｂ）に示すように境界部１２ｂ２２’を介しその前後にそれぞれロック用係合面１２ｂ２３’と仮止め用係合面１２ｂ２４’とを設ける。 And in base side convex part 12b2 'of band clamp 1' of Embodiment 2, as shown to FIG.22 (b)-FIG.25 (b), it is each engaged on the front and back via the boundary part 12b22 ', respectively. 12b23 'and provisional engagement surface 12b24' are provided.

尚、実施形態２のバンド締付け具１’では、本発明の全開状態保持機構を構成するレバー側凸部１１ａ４’と、ベース側凸部１２ｂ２’の構成以外は、実施形態１のバンド締付け具１の構成とほぼ同じである。 In the band fastener 1 ′ of the second embodiment, the band fastener 1 of the first embodiment is the same as the configuration of the lever-side convex portion 11a4 ′ and the base-side convex portion 12b2 ′ constituting the fully opened state holding mechanism of the present invention. The configuration is almost the same.

＜実施形態２のバンド締付け具１’の作用＞
次に、実施形態２のバンド締付け具１’の作用について説明する。
以上のように構成された実施形態２のバンド締付け具１’でも、帯状バンド２を電柱３の外周に巻き回した後、図２３（ａ），（ｂ）に示すように、帯状バンド２の一端（先端部）を全開状態にある操作レバー１１’のバンド巻込み軸１１ａ’のバンド挿通孔１１ａ１’のバンド入口１１ａ１１’側からバンド出口１１ａ１２’側へ通す。 <Operation of Band Fastener 1 ′ of Embodiment 2>
Next, the operation of the band fastener 1 ′ of the second embodiment will be described.
Even in the band fastener 1 ′ of the second embodiment configured as described above, after the belt-like band 2 is wound around the outer periphery of the utility pole 3, as shown in FIGS. One end (tip) is passed from the band inlet 11a11 ′ side of the band insertion hole 11a1 ′ of the band winding shaft 11a ′ of the operating lever 11 ′ in the fully opened state to the band outlet 11a12 ′ side.

ここで、その全開状態の際、実施形態２のバンド締付け具１’でも、図２３（ａ），（ｂ）に示すように、本発明の全開状態保持機構を構成する操作レバー１１’のレバー側凸部１１ａ４’が、ベース１２’のベース側凸部１２ｂ２’のロック用係合面１２ｂ２３’に対し弾接状態で位置しており、操作レバー１１’がベース１２’に対し最大限開いた全開状態を保持している。 Here, in the fully open state, as shown in FIGS. 23 (a) and 23 (b), the lever of the operation lever 11 'constituting the fully open state holding mechanism of the present invention is also used in the band fastener 1' of the second embodiment. The side convex portion 11a4 ′ is positioned in an elastic contact state with the locking engagement surface 12b23 ′ of the base side convex portion 12b2 ′ of the base 12 ′, and the operating lever 11 ′ is opened to the maximum with respect to the base 12 ′. The fully open state is maintained.

そのため、実施形態２のバンド締付け具１’でも、実施形態１のバンド締付け具１と同様に、操作レバー１１’が勝手に回動することを防止でき、バンド巻取軸１１ａ’のバンド貫通孔１１ａ１’への帯状バンド２の挿通作業が簡単になり、帯状バンド２の締め付け作業性を向上させることができる。 Therefore, similarly to the band clamp 1 of the first embodiment, the band clamp 1 ′ of the second embodiment can prevent the operation lever 11 ′ from rotating freely, and the band through-hole of the band winding shaft 11a ′. The work of inserting the belt-like band 2 into 11a1 ′ is simplified, and the workability of tightening the belt-like band 2 can be improved.

また、実施形態２のバンド締付け具１’でも、実施形態１のバンド締付け具１と同様に、操作レバー１１’が全開状態保持機構により全開状態でベース１２’にロックされた状態では、図２３（ａ），（ｂ）に示すように、バンド巻取軸１１ａ’のバンド貫通孔１１ａ１’は、ほぼベース１２’とほぼ平行になり、しかもバンド貫通孔１１ａ１’のバンド入口１１ａ１１’およびバンド出口１１ａ１２’がベース１２’の上面よりも高くなるように構成されているため、この点でも、バンド巻取軸１１ａ’のバンド貫通孔１１ａ１’への帯状バンド２の挿通作業が簡単になり、帯状バンド２の締め付け作業性を向上させることができる。 Also, in the band clamp 1 ′ of the second embodiment, as in the band clamp 1 of the first embodiment, when the operation lever 11 ′ is locked to the base 12 ′ in the fully open state by the fully open state holding mechanism, FIG. As shown in (a) and (b), the band through-hole 11a1 ′ of the band winding shaft 11a ′ is substantially parallel to the base 12 ′, and the band inlet 11a11 ′ and the band outlet of the band through-hole 11a1 ′. Since 11a12 ′ is configured to be higher than the upper surface of the base 12 ′, the band-like band 2 can be easily inserted into the band through-hole 11a1 ′ of the band winding shaft 11a ′. The workability of tightening the band 2 can be improved.

次に、図２３（ａ），（ｂ）に示す操作レバー１１’の全開状態から図２４（ａ），（ｂ）に示すように操作レバー１１’をα方向に若干回動させても、操作レバー１１’のレバー側凸部１１ａ４’がベース１２’のベース側凸部１２ｂ２’の境界部１２ｂ２２’を乗り越えるまでは、レバー側凸部１１ａ４’がベース１２’のベース側凸部１２ｂ２’のロック用係合面１２ｂ２３’に弾接して係合するため、操作レバー１１’から手を離すと帯状バンド２のテンション（引張力）も合わさり全開状態に戻ろうとする。 Next, even if the operation lever 11 ′ is slightly rotated in the α direction as shown in FIGS. 24 (a) and (b) from the fully opened state of the operation lever 11 ′ shown in FIGS. 23 (a) and (b), Until the lever side convex portion 11a4 ′ of the operation lever 11 ′ gets over the boundary portion 12b22 ′ of the base side convex portion 12b2 ′ of the base 12 ′, the lever side convex portion 11a4 ′ of the base side convex portion 12b2 ′ of the base 12 ′ Since the lock engaging surface 12b23 ′ is elastically contacted and engaged, when the hand is released from the operation lever 11 ′, the tension (tensile force) of the belt-like band 2 is also brought together to return to the fully opened state.

そして、図２４（ａ），（ｂ）に示す状態から、操作レバー１１’をα方向にさらに回動させると、図２５（ａ），（ｂ）に示すように操作レバー１１’のレバー側凸部１１ａ４’がベース１２’のベース側凸部１２ｂ２’の境界部１２ｂ２２’を乗り越えて仮止め用係合面１２ｂ２４’に係合して、ロック用係合面１２ｂ２３’に係合しなくなる。 When the operation lever 11 ′ is further rotated in the α direction from the state shown in FIGS. 24 (a) and 24 (b), the lever side of the operation lever 11 ′ is shown in FIGS. 25 (a) and 25 (b). The convex portion 11a4 ′ gets over the boundary portion 12b22 ′ of the base-side convex portion 12b2 ′ of the base 12 ′, engages with the temporarily fixing engagement surface 12b24 ′, and stops engaging with the locking engagement surface 12b23 ′.

そのため、実施形態１のバンド締付け具１と同様に、作業者が操作レバー１１’から手を離したり、α方向に操作レバー１１’を回動する力を緩めても、レバー側凸部１１ａ４’がベース側凸部１２ｂ２’の仮止め用係合面１２ｂ２４’に当接して係合しているので、レバー側凸部１１ａ４’がベース側凸部１２ｂ２’の仮止め用係合面１２ｂ２４’および境界部１２ｂ２２’を乗り越えるような力を操作レバー１１’に掛けない限り、操作レバー１１’は全開状態へ戻らない。 Therefore, similarly to the band fastening tool 1 of the first embodiment, even if the operator releases his / her hand from the operation lever 11 ′ or loosens the force to rotate the operation lever 11 ′ in the α direction, the lever side convex portion 11a4 ′. Is in contact with and engaged with the temporary engagement surface 12b24 ′ of the base-side convex portion 12b2 ′, the lever-side convex portion 11a4 ′ and the temporary-fixing engagement surface 12b24 ′ of the base-side convex portion 12b2 ′ and The operation lever 11 ′ does not return to the fully open state unless a force is applied to the operation lever 11 ′ over the boundary portion 12b22 ′.

つまり、図２５（ａ），（ｂ）に示す状態は、作業者が操作レバー１１’から手を離しても、操作レバー１１’を閉めるα方向およびその逆方向に回動せず、かつ、バンド巻取軸１１ａ’のバンド貫通孔１１ａ１’に通した帯状バンド２’が抜けない仮止め状態であるため、作業者は、図２５（ａ），（ｂ）に示す仮止め状態で、バンド締付け具１’や帯状バンド２の位置等を簡単に調整することができる。 That is, in the state shown in FIGS. 25A and 25B, even if the operator releases his / her hand from the operation lever 11 ′, the operator does not rotate in the α direction for closing the operation lever 11 ′ and the opposite direction, and Since the band-shaped band 2 ′ that has passed through the band through-hole 11 a 1 ′ of the band winding shaft 11 a ′ is in a temporarily fixed state that does not come off, the operator can use the band in the temporarily fixed state shown in FIGS. 25 (a) and 25 (b). It is possible to easily adjust the position of the fastener 1 ′ and the band 2.

そして、操作レバー１１’をさらにα方向に回動させ、図２６（ａ），（ｂ）に示すように操作レバー１１’がベース１２’に対し全閉状態になると、操作レバー１１’先端の係止部１１ｃ’，１１ｃ’がベース１２’先端の被係止部１２ｃ’，１２ｃ’に係止して、帯状バンド２の締め付けが完了する。 Then, when the operation lever 11 ′ is further rotated in the α direction and the operation lever 11 ′ is fully closed with respect to the base 12 ′ as shown in FIGS. The locking portions 11c ′ and 11c ′ are locked to the locked portions 12c ′ and 12c ′ at the tip of the base 12 ′, and the tightening of the belt-like band 2 is completed.

従って、実施形態２のバンド締付け具１’によれば、実施形態１のバンド締付け具１と全開状態保持機構の構成が異なるものの、全開状態保持機構以外の構成はほぼ同様であるので、上述した実施形態１と同様の効果が得られる。 Therefore, according to the band fastener 1 ′ of the second embodiment, the configuration of the fully open state holding mechanism is different from that of the band fastener 1 of the first embodiment, but the configuration other than the fully open state holding mechanism is substantially the same. The same effect as in the first embodiment can be obtained.

また、実施形態２のバンド締付け具１’でも、全開状態保持機構を構成するレバー側凸部１１ａ４’はバンド貫通孔１１ａ１’のバンド入口１１ａ１１’側に近い操作レバー１１’に設ける一方、ベース側凸部１２ｂ２’はベース１２’の基端側に設けたので、ベース１２’に対し操作レバー１１’の起立角度β’（図２５（ａ）参照。）が小さい角度、すなわち操作レバー１１’を少ない操作量で仮止め（仮留め）することが可能になり、この点でも帯状バンド２の締め付け作業性を向上させることができる。 Also, in the band clamp 1 ′ of the second embodiment, the lever-side convex portion 11a4 ′ constituting the fully opened state holding mechanism is provided on the operation lever 11 ′ close to the band inlet 11a11 ′ side of the band through-hole 11a1 ′, while the base side Since the convex portion 12b2 ′ is provided on the base end side of the base 12 ′, an angle at which the rising angle β ′ of the operation lever 11 ′ (see FIG. 25A) is small with respect to the base 12 ′, that is, the operation lever 11 ′ is set. Temporary fastening (temporary fastening) can be performed with a small amount of operation, and also in this respect, tightening workability of the belt-like band 2 can be improved.

尚、実施形態１のバンド締付け具１と、実施形態２のバンド締付け具１’とを比較すると、実施形態１のバンド締付け具１の方が全開状態保持機構を構成するレバー側凸部１１ａ４とベース側凸部１２ｂ２との係合部分の幅が広いので、より安定した状態で全開状態や仮止め状態を保持できる。 When comparing the band clamp 1 of the first embodiment with the band clamp 1 ′ of the second embodiment, the band clamp 1 of the first embodiment has a lever-side convex portion 11a4 that constitutes a fully open state holding mechanism. Since the width of the engaging portion with the base-side convex portion 12b2 is wide, the fully opened state and the temporarily fixed state can be maintained in a more stable state.
