本考案は、ホースを固定するのに使用されるホ
ースバンドに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hose band used to secure a hose.
従来から用いられている両端開放形のホースバ

止孔４の当り面７はほぼ垂直に打抜かれていた。
As shown in FIG. 5, a conventionally used hose band with both ends open is formed by rolling a metal band member 2 constituting a hose band 1 into a ring shape, and then attaching both ends of the band member 2 to each other. After the protrusion 3 and the locking hole 4 are fitted in a stacked state on the inside and outside, the ear part 5 is plastically deformed to reduce the ring diameter and tighten the hose. The protrusion 3 is made to protrude obliquely toward the end 2a side of the band-shaped member in order to prevent it from coming off from the locking hole 4. The contact surface 7 of the locking hole 4 that contacts the inner surface 3a of the protrusion was punched out almost vertically.
このように突起３が斜めに突出しかつ当り面７
が垂直の場合、締付け力Ｆが働くと、突起３の内
面３ａは当り面７の外側の角部７ａに接触する。
すなわち、板厚分だけ突起３の先端寄りの箇所で
荷重を受けることになる。
In this way, the protrusion 3 projects diagonally and the contact surface 7
is vertical, when the tightening force F is applied, the inner surface 3a of the protrusion 3 comes into contact with the outer corner 7a of the contact surface 7.
In other words, a load is received at a location closer to the tip of the protrusion 3 by the thickness of the plate.
このため従来品では、帯状部材２を締付けた時
に突起３を引起こす方向に曲げモーメントが働
き、強く締付け過ぎると突起３が変形したり折れ

かつた。第７図は従来の突起３の強度を実測した
もので、約、320Kg付近で突起が破損したことが
示されている。 For this reason, in conventional products, when the band member 2 is tightened, a bending moment acts in the direction that causes the protrusion 3, and if the band member 2 is tightened too strongly, the protrusion 3 may deform or break, making it impossible to increase the tightening force. . FIG. 7 shows actual measurements of the strength of the conventional protrusion 3, and shows that the protrusion broke at approximately 320 kg.
本考案は、両端が開放された金属製の帯状部材
からなり、この帯状部材をリング状に丸めてその
両端部を互いに内側と外側に重ねた状態で使用さ
れるホースバンドに適用される。
The present invention is applied to a hose band that is made of a metal band-like member with both ends open, and is used with this band-like member rolled into a ring shape and both ends overlapped inside and outside of each other.
本考案のホースバンドは、上記帯状部材の外側

たことを特徴とするホースバンドである。 In the hose band of the present invention, a locking hole is formed in the outer overlapping portion of the band-like member, and a protrusion that engages with the locking hole is provided in the inner overlapping portion of the band-like member. This protrusion has a shape that projects obliquely toward the end of the outer overlapping part, and the contact surface of the locking hole that contacts the inner surface of this protrusion is inclined at an angle that is approximately equal to or greater than the inclination angle of the inner surface of the protrusion. This is a hose band that is characterized by
〔作用〕
上記構成のホースバンドは、突起を係止孔に嵌
合させた状態で帯状部材の一部を塑性変形させる
ことにより、リングの径を縮小させてホースを締
付ける。[Operation] The hose band configured as described above plastically deforms a portion of the band member with the protrusion fitted into the locking hole, thereby reducing the diameter of the ring and tightening the hose.
係止孔の当り面は、突起の内面の傾斜角とほぼ
同等もしくはこれよりも大きな角度に傾斜してい
るから、当り面は突起の先端側ではなく、付け根
側で当るようになる。このため、バンドを締付け
た時に突起に働く曲げモーメントが小さくなり、
締付け力に対して大きな強度が得られる。 Since the abutting surface of the locking hole is inclined at an angle substantially equal to or greater than the inclination angle of the inner surface of the protrusion, the abutting surface comes into contact with the base of the protrusion, not the tip side. Therefore, the bending moment acting on the protrusion when the band is tightened becomes smaller.
Great strength against tightening force can be obtained.

In one embodiment shown in FIGS. 1 to 3, the hose band 10 is made of a band-shaped member 11 made of metal such as stainless steel. Both ends of this strip member 11 are open free ends. Like the hose band shown in FIG. 5, the band member 11 is rolled into a ring shape when in use, and the protrusion 14 is fitted into the locking hole 13 with both ends overlapped inside and outside. are connected by this. The locking hole 13 is connected to the belt-shaped member 11
It is formed on one end side, that is, on the outer overlapping portion 11a.

る。 The protrusion 14 is provided on the other end side of the strip member 11, that is, on the inner overlapping portion 11b. As shown in FIG. 1, the protrusion 14 is obliquely projected in a shape facing toward the end 11c of the outer overlapping portion, and has an arch-like cross-sectional shape that swells outward. Slanted inner surfaces 16 having an inclination angle θ 1 are formed on both sides of the protrusion 14 .

態で固定する。 The hose band 10 having the above configuration includes a band member 11
Open both ends of the hose and wrap it around the outside of the hose.
The protrusion 14 is fitted into the locking hole 13. Then, a part (ear part) of the band-shaped member 11 is plastically deformed using a jig. As a result, the strip member 11 is pulled in a direction in which its diameter is reduced, and the hose is thus fixed in a strongly tightened state.

ることができる。 The above tightening force is applied in the direction in which the inner surface 16 of the protrusion 14 and the contact surface 18 of the locking hole 13 abut against each other. Therefore, the contact surface 18 that supports the protrusion 14 has an inclination angle θ 1 approximately equal to or θ 1 of the inner surface 16 of the protrusion.
Since the contact surface 18 is inclined at an angle θ 2 that is slightly larger than the angle θ 2 , the contact surface 18 comes into contact with the inner surface 16 of the protrusion near the base or comes into surface contact with the inner surface 16 of the protrusion. For this reason,
The bending moment acting in the direction of causing the protrusion 14 is sufficiently smaller than that of the conventional product (see FIG. 6), or is substantially eliminated. Therefore, the protrusion 14 can withstand a large tightening force.

ル性能も従来品に比べて向上する。 FIG. 4 shows the results of actually measuring the strength of the protrusion 14 of this example. The height of the protrusion 14 is approximately 3 mm. In the figure, the protrusion 14 can withstand a force of about 420 kg, and the tightening force can be increased by about 100 kg compared to the conventional product shown in FIG. Therefore, the sealing performance is also improved compared to conventional products.

ようにしてもよい。 Note that two or more sets of locking holes 13 and protrusions 14 may be provided in the longitudinal direction of the strip member 11 to prevent lateral displacement and to withstand even greater tightening force.

According to the hose band of the present invention, the strength of the protrusion against the clamping force is improved, and the clamping force can be increased.
