この突部４５が、バンド部材２０の拡径時に、膨出部３５の両側部３７に設けた嵌合孔３７ａの一端側に配置され（図６参照）、バンド部材２０の縮径時に、同嵌合孔３７ａの他端側に移動して（図７参照）、嵌合孔３７ａ内で突部４５が遊嵌するようになっている。なお、各突部４５は、その先端がバネ部材中央に向けて突出した形状をなしており（図４参照）、この突部４５の先端が、嵌合孔３７ａの表側に配置されることで、バンド部材２０の嵌合孔３７ａに遊嵌する突部４５が、同嵌合孔３７ａから抜けにくくなっている（図６及び図７参照）。 The protrusion 45 is disposed at one end of a fitting hole 37 a provided on both sides 37 of the bulging portion 35 when the band member 20 is expanded in diameter (see FIG. 6). The protrusion 45 moves to the other end of the fitting hole 37a (see FIG. 7), and the protrusion 45 is loosely fitted in the fitting hole 37a. Each of the protrusions 45 has a shape in which the tip protrudes toward the center of the spring member (see FIG. 4), and the tip of the protrusion 45 is disposed on the front side of the fitting hole 37a. The protrusion 45 that fits loosely into the fitting hole 37a of the band member 20 does not easily come off from the fitting hole 37a (see FIGS. 6 and 7).
また、基部４１の一端側であって第２延出部４４とは反対側の部分、及び、基部４１の他端側であって第１延出部４３とは反対側の部分は、バンド部材外径側に向けて、略Ｕ字状をなすように屈曲されてると共に、この屈曲した部分の先端部４６ａが、基部表面側に向けて折り返された形状をなしており、これによってバネ部４６，４６が形成されている（図４参照）。なお、図５に示すように、バネ部材４０を平面的に見たときに、第１延出部４３及び第２延出部４４、第１延出部先端側の突部４５及び第２延出部先端側の突部４５、更に第１延出部基端側のバネ部４６及び第２延出部基端側のバネ部４６は、それぞれ斜めに対向した位置に互い違いとなるように配置されている。 Also, a portion on one end side of the base 41 and opposite to the second extension portion 44 and a portion on the other end side of the base 41 and opposite to the first extension portion 43 are band members. It is bent toward the outer diameter side so as to form a substantially U-shape, and the distal end portion 46a of the bent portion has a shape folded back toward the base surface side. , 46 are formed (see FIG. 4). As shown in FIG. 5, when the spring member 40 is viewed in a plan view, the first extension 43 and the second extension 44, the projection 45 on the distal end side of the first extension and the second extension The protruding portion 45 on the distal end side of the protruding portion, and the spring portion 46 on the proximal end side of the first extension portion and the spring portion 46 on the proximal end side of the second extension portion are arranged so as to be staggered at mutually opposing positions. Have been.
なお、上記バネ部材の形状は一例であって、上記形状に限定されるものではなく、締め付け手段によりバンド部材がホースに対して締め付け固定された状態で、膨出部の内周を押圧して、バンド部材に締め付け力を付与可能なものであれば、どのような形状であってもよい。 Note that the shape of the spring member is an example, and is not limited to the above shape.In a state where the band member is fastened and fixed to the hose by the fastening means, the inner periphery of the bulging portion is pressed. Any shape may be used as long as a tightening force can be applied to the band member.
そして、図８に示すように、バンド部材２０の一端部２１と他端部２３とを重ね合わせない状態で、バンド部材２０の径方向内方から膨出部３５へ向けて、一端部２１に設けた膨出部３５に向けてバネ部材４０を押し込んで、バネ部材４０の突部４５，４５を、膨出部３５の周方向両側の嵌合孔３７ａ，３７ａに遊嵌させることで、膨出部３５にバネ部材４０を組付け可能となっている。 Then, as shown in FIG. 8, in a state where the one end 21 and the other end 23 of the band member 20 are not overlapped, the band member 20 is moved from the radial inside to the bulging portion 35 to the one end 21. The spring member 40 is pushed toward the provided bulging portion 35, and the protrusions 45, 45 of the spring member 40 are loosely fitted into the fitting holes 37 a, 37 a on both sides in the circumferential direction of the bulging portion 35. The spring member 40 can be attached to the protrusion 35.
すなわち、この実施形態においては、膨出部３５は、その膨出方向の先端側から基端側に向かって末広がり状に伸びる山形状をなしており、その内側が開口しているため、図８に示すように、バンド部材２０の径方向内方から膨出部３５へ向けて、バネ部材４０を組付け可能に構成されている。そのため、バンド部材の軸方向側から膨出部にバネ部材を組付ける場合と比べて、バネ部材４０を容易に組付けることでき、バネ部材４０の組付け作業性を向上させることができる。 That is, in this embodiment, the swelling portion 35 has a mountain shape that extends divergently from the distal end side to the base end side in the swelling direction, and the inside is open. As shown in FIG. 5, the spring member 40 is configured to be able to be assembled from the radially inner side of the band member 20 toward the bulging portion 35. Therefore, as compared with the case where the spring member is assembled to the bulging portion from the axial direction side of the band member, the spring member 40 can be easily assembled, and the workability of assembling the spring member 40 can be improved.
上記状態で、他端部２３側の第１係合爪３１を一端部２１側の係合突起２７に係合させることで、バンド部材２０が拡径した状態に維持されると共に、一端部２１が他端部２３の外周側に重なって重なり部２５が形成され、膨出部３５に対して他端部２３が対向して配置されて、膨出部３５と、他端部２３の膨出部対向配置部分２３Ａとの間に、バネ部材４０が収容配置され、バネ部材４０が抜け止め状態でバンド部材２０に装着される（図２及び図３参照）。 In this state, the band member 20 is maintained in an expanded state by engaging the first engagement claws 31 on the other end 23 with the engagement protrusions 27 on the one end 21, and the one end 21 Are overlapped on the outer peripheral side of the other end portion 23 to form an overlapping portion 25, and the other end portion 23 is arranged to face the bulging portion 35, and the bulging portion 35 and the bulging portion The spring member 40 is housed and arranged between the part facing portion 23A and the spring member 40 is attached to the band member 20 in a state where the spring member 40 is prevented from falling off (see FIGS. 2 and 3).
なお、この状態では、図３に示すように、バネ部材４０の第１延出部４３及び第２延出部４４が、膨出部３５の周方向の両側部３７，３７と、他端部２３の膨出部対向配置部分２３Ａとの間にそれぞれ挟持されると共に、バネ部４６，４６が、膨出部３５の中央部３６内に収容されて、その先端部４６ａが同中央部３６の内周面に当接するようになっている。 In this state, as shown in FIG. 3, the first extending portion 43 and the second extending portion 44 of the spring member 40 are configured such that the circumferential side portions 37, 37 of the bulging portion 35 and the other end portion. The spring portions 46, 46 are housed in the central portion 36 of the bulging portion 35, and the tip portion 46a of the spring portion 46 is held between the central portion 36 of the central portion 36. It comes into contact with the inner peripheral surface.
そして、上記のようにバンド部材２０の拡径状態から、第１***部２８と第２***部３０とを離反させて、第２係合爪３２を係合突起２７に係合させることによって、バンド部材２０が縮径状態に維持されて、バンド部材２０がホースＨに対して締め付け固定される。このとき、図７に示すように、膨出部３５によってバネ部材４０，４０のバネ部４６が押し潰されて弾性変形すると共に、同バネ部４６の弾性復帰力によって、膨出部３５の内周がバンド部材外径側に押圧されるので（矢印Ｆ１参照）、膨出部３５の両側に、互いに近づく方向の引張り力Ｆ２，Ｆ２がそれぞれ作用し、その結果、バンド部材２０の一端部２１と他端部２３との重なり量が増える方向となるように、バンド部材２０が締め付けられることとなる。 Then, by separating the first raised portion 28 and the second raised portion 30 from the expanded diameter state of the band member 20 as described above, the second engaging claw 32 is engaged with the engaging protrusion 27, The band member 20 is maintained in a reduced diameter state, and the band member 20 is tightened and fixed to the hose H. At this time, as shown in FIG. 7, the spring portions 46 of the spring members 40, 40 are crushed and elastically deformed by the swelling portions 35, and the elastic return force of the spring portions 46 causes the inner portions of the swelling portions 35. Since the circumference is pressed toward the outer diameter side of the band member (see arrow F1), tensile forces F2 and F2 in directions approaching each other act on both sides of the bulging portion 35, and as a result, one end 21 of the band member 20 The band member 20 is tightened such that the overlapping amount between the band member 20 and the other end 23 increases.
次に、上記構成からなるクランプ１０を用いて、ゴム等の材質からなる可撓性のホースＨを、パイプ等の配管Ｐに締め付け固定する際の手順について説明する。 Next, a procedure for tightening and fixing a flexible hose H made of a material such as rubber to a pipe P such as a pipe using the clamp 10 having the above configuration will be described.
すなわち、図１及び図３に示すように、他端部２３側の第１係合爪３１を一端部２１側の係合突起２７に係合させて、バンド部材２０が拡径した状態で、配管Ｐの一端に外装されたホースＨの外周に、ホースクランプ１０を配置する。 That is, as shown in FIGS. 1 and 3, in a state where the first engaging claw 31 on the other end 23 is engaged with the engaging protrusion 27 on the one end 21, and the band member 20 is expanded in diameter, The hose clamp 10 is arranged on the outer periphery of the hose H provided at one end of the pipe P.
この状態で、第１***部２８と第２***部３０とを離反させて、第２係合爪３２を係合突起２７に係合させることによって、バンド部材２０が縮径状態に維持されて、バンド部材２０がホースＨに対して締め付け固定されて、配管Ｐに対してホースＨを連結させることができる。 In this state, the first protrusion 28 and the second protrusion 30 are separated from each other, and the second engagement claws 32 are engaged with the engagement protrusions 27, whereby the band member 20 is maintained in the reduced diameter state. The band member 20 is fastened and fixed to the hose H, so that the hose H can be connected to the pipe P.
このとき、上述したように、膨出部３５によりバネ部材４０，４０のバネ部４６が押し潰されて、バネ部材４０の弾性復元力によって、膨出部３５の内周が押圧されるので（図７参照）、ホースＨに対して弾性力を介してバンド部材２０を締め付けることができ、配管Ｐに対してホースＨをよりしっかりと連結することができる。また、図７の矢印Ｆ２に示すように、膨出部３５の両側に互いに近づく方向の引張り力Ｆ２，Ｆ２がそれぞれ作用するので、膨出部３５のへたりや伸びを抑制することができる。 At this time, as described above, the spring portion 46 of the spring members 40, 40 is crushed by the bulging portion 35, and the inner periphery of the bulging portion 35 is pressed by the elastic restoring force of the spring member 40 ( 7), the band member 20 can be tightened to the hose H via an elastic force, and the hose H can be more firmly connected to the pipe P. Further, as shown by the arrow F2 in FIG. 7, since the pulling forces F2 and F2 in the directions approaching each other act on both sides of the bulging portion 35, it is possible to suppress the sag and elongation of the bulging portion 35.
そして、このホースクランプ１０においては、バンド部材２０の一端部２１に形成された膨出部３５と、他端部２３の膨出部対向配置部分２３Ａとの間に、バネ部材４０が配置されているので、バネ部材４０のバンド部材内径側には、バンド部材２０の他端部２３が配置されることとなり、ホースＨの外周に接触するバンド部材２０の他端部２３の内周面に継ぎ目を増やすことなく、バネ部材４０を配置することができるため、ホースＨに対する締め付け圧力を、バンド部材２０の他端部２３側において分断させることなく、配管Ｐに対してホースＨをしっかりと締め付けることができる（図７参照）。 In the hose clamp 10, a spring member 40 is disposed between a bulging portion 35 formed at one end 21 of the band member 20 and a bulging portion facing arrangement portion 23 </ b> A of the other end 23. Therefore, the other end portion 23 of the band member 20 is disposed on the inner side of the band member of the spring member 40, and the inner peripheral surface of the other end portion 23 of the band member 20 that comes into contact with the outer periphery of the hose H is joined. Since the spring member 40 can be arranged without increasing the pressure, the hose H can be securely tightened to the pipe P without breaking the tightening pressure on the hose H on the other end 23 side of the band member 20. (See FIG. 7).
また、この実施形態においては、バンド部材２０の膨出部３５の周方向両側に嵌合孔３７ａ，３７ａが形成され、バネ部材４０は、他端部２３の外周に配置される基部４１を有しており、該基部４１は、その両端側に、バンド部材２０の外径側に突出して設けられて、膨出部３５の嵌合孔３７ａ，３７ａに遊嵌する突部４５，４５を有している。そのため、バネ部材４０の突部４５，４５を、膨出部３５の両側の嵌合孔３７ａ，３７ａにそれぞれ遊嵌させるだけの簡単な作業で、バンド部材２０に対してバネ部材４０を組付けることができ、バネ部材４０の組付け作業性をより向上させることができる。更に、この実施形態のバネ部材４０は、前記基部４１と、前記突部４５，４５と、基部４１の所定位置に設けられ、膨出部３５の内周を押圧可能とするバネ部４６とが一体形成されているので、バンド部材２０に対するバネ部材４０の組付け保持と、膨出部３５の伸びや変形の抑制とを、同一部材で効率的に図ることができる。 Further, in this embodiment, fitting holes 37a, 37a are formed on both sides in the circumferential direction of the bulging portion 35 of the band member 20, and the spring member 40 has a base 41 disposed on the outer periphery of the other end 23. The base portion 41 has, at both ends thereof, projecting portions 45, 45 protruding toward the outer diameter side of the band member 20 and loosely fitting into the fitting holes 37a, 37a of the bulging portion 35. are doing. For this reason, the spring member 40 is attached to the band member 20 by a simple operation in which the protrusions 45, 45 of the spring member 40 are loosely fitted into the fitting holes 37a, 37a on both sides of the bulging portion 35, respectively. Accordingly, the workability of assembling the spring member 40 can be further improved. Further, the spring member 40 of this embodiment includes the base 41, the protrusions 45, 45, and a spring 46 provided at a predetermined position of the base 41 and capable of pressing the inner periphery of the bulging portion 35. Because they are integrally formed, the same member can efficiently achieve the assembly and holding of the spring member 40 with respect to the band member 20 and the suppression of expansion and deformation of the bulging portion 35.
更にこの実施形態においては、図４及び図５に示すように、バネ部材４０の基部４１の一端側から、バンド部材２０の幅方向一側に沿って第１延出部４３が延び、基部４１の他端側から、バンド部材２０の幅方向他側に沿って、第１延出部４３の延出方向と反対側に向けて第２延出部４４が延びており、これらの第１延出部４３及び第２延出部４４の先端側に突部４５，４５がそれぞれ形成されると共に、基部４１の一端側であって第２延出部４４とは反対側、及び、基部４１の他端側であって第１延出部４３とは反対側に、バネ部４６，４６がそれぞれ設けられている。そのため、バネ部材４０を平面的に見たときに、第１延出部４３及び第２延出部４４、第１延出部先端側の突部４５及び第２延出部先端側の突部４５、更に第１延出部基端側のバネ部４６及び第２延出部基端側のバネ部４６は、それぞれ斜めに対向するように互い違いに配置されることとなり、バネ部材４０を、膨出部３５と、他端部２３の膨出部対向配置部分２３Ａとの間に配置したときに、転びにくくすることができると共に、金属板材をカットして適宜折曲してバネ部材４０を形成する際の、無駄を抑制して歩留まりを向上させることができる。 Further, in this embodiment, as shown in FIGS. 4 and 5, a first extension 43 extends from one end of the base 41 of the spring member 40 along one side in the width direction of the band member 20, and the base 41 The second extension 44 extends from the other end of the band member along the other side in the width direction of the band member 20 in a direction opposite to the direction in which the first extension 43 extends. Protrusions 45 and 45 are formed on the distal end sides of the protruding portion 43 and the second extending portion 44, respectively, and one end side of the base 41 and the side opposite to the second extending portion 44, and the Spring portions 46, 46 are provided on the other end side and opposite to the first extension portion 43, respectively. Therefore, when the spring member 40 is viewed in a plan view, the first extension portion 43 and the second extension portion 44, the projection 45 on the tip side of the first extension portion, and the projection portion on the tip side of the second extension portion. 45, the spring portion 46 on the first extension portion proximal end side and the spring portion 46 on the second extension portion proximal end side are alternately arranged so as to be obliquely opposed to each other. When the spring member 40 is disposed between the swelling portion 35 and the swelling portion facing arrangement portion 23A of the other end portion 23, the spring member 40 can be hardly rolled, and the spring member 40 can be cut and bent as needed. In forming, waste can be suppressed and the yield can be improved.
