この考案は、ホース等の締付けに使用する金属
製結合バンドに関するものである。[Detailed Description of the Invention] This invention relates to a metal coupling band used for tightening hoses and the like.

又、ナツト、ボルト等構成部品が多く加工コスト
が高くなり価格が割高であると共に重量が重い。 Conventionally, this type of coupling band has been tightened using screws such as nuts and bolts. However, this type of conventional band has the following drawbacks. That is, the above-mentioned coupling bands, which are tightened using screws such as nuts and bolts, have protrusions and dangerous obstructions exposed on the outer periphery, making them unsuitable for use in narrow spaces or rotating places.
Furthermore, since there are many components such as nuts and bolts, the processing cost is high, the price is relatively high, and the weight is heavy.

ようになしたものがある。 As shown in FIG. 9, another type of bonding band is a ring-shaped steel strip 10 with both ends overlapped, spanning the overlapping part, having a rounded edge part 11 in the center, and cutting up into band parts 12 at both ends. A tightening fitting 14 having a piece 13 is attached so that the cut-and-raised piece 13 fits into a through hole 15 provided on the surface of the steel band 10, and the side wall of the ear part 11 is crushed to shrink the steel band 10. There is one that has a diameter.

潰し難いという弊害がある。 However, in the case of the above-mentioned joint band, both ends of the steel strip 10 are overlapped, and the fastening metal fittings 1 are attached outwardly.
Since the band part 12 of No. 4 is applied, the ear part 1
During tightening to crush the side wall of the steel strip 10, one end of the steel strip 10 is between the outer surface of the hose etc. and the other end, and the other end is between the outer surface of the hose etc. Strong frictional force is generated between the band portion 12 and tightening is difficult. In particular, this frictional force is significant in the latter half of tightening, so it may not be possible to tighten to the required strength. In addition, through holes 15 are formed on the surface of the steel strip 10.
When tightening, the outer surface of the hose bulges into the through hole 15, making tightening even more difficult. Furthermore, it has many drawbacks, such as the outer surface of the hose being damaged by the tip of the cut-and-raised piece 13. Furthermore,
Separable type steel strips 10, in which both ends are separated, are convenient as they can be attached directly to the outer wall of the object to be fastened, but all conventional separable type fasteners are As shown in the fitting 14, the cut-out piece 13 of the fastening fitting 14 is attached to the steel strip 10.
In addition to the above-mentioned drawbacks, the cut-out piece 1 is fixed to the through hole 15 due to the resistance force during tightening.
3 is easily deformed and comes off from the hole 15, and the material for the fastening fitting 14 must be stronger than necessary, and conversely, the material must be too strong. There is a disadvantage that it is difficult to crush the side wall of the ear portion 11 used.
本考案は、公知の従来の結合バンドの上記欠点
に鑑み、之れを改良除去したもので、即ち構造簡
単にして取付けの手数が掛らず、締付けが強固で
しかも外側に突起物や邪魔物がなく、外観が優美

るものである。 In view of the above-mentioned drawbacks of the known conventional coupling bands, the present invention has been developed to improve and eliminate these drawbacks.In other words, the structure is simple, the installation process is simple, the tightening is strong, and there are no protrusions or obstructions on the outside. It is an object of the present invention to provide a coupling band which has excellent effects such as an elegant appearance, easy manufacture, and low material cost.
以下、この考案の構成を図面に示す実施例に基
ずいて説明すると次の通りである。 The configuration of this invention will be explained below based on the embodiments shown in the drawings.

As shown in Fig. 4, bent pieces 2'', 2'' are formed at both ends 2', 2', and holes 2, 2 are provided in which the bent parts at both ends of the steel strip fit, respectively. There is.
This fastening fitting does not bend because it has reinforced parts at parts a, b, and c, but only bends at parts d and e, which are not reinforced.

８図は締付後の状態を示す。 FIG. 6 shows a plate 3 for compensating for the lack of sealing performance due to gaps G generated near both ends of the steel band during tightening. This plate 3 is made of a thin steel strip plate having the same curvature as the steel strip 1, and has bent pieces 3'' formed above both lines over the entire length in the direction of curvature.
As shown in FIG. 7, the steel strip is fitted across both ends of the steel strip, and one end 3' is attached to the steel strip 1 with a bent piece 3. ``Protrusions 3 provided on both inner sides prevent the plate from coming off.Also, the protrusions 3 may be provided on both ends.The plate 3 will not come off, but the steel strip 1 will not come off.
It is designed so that it can be easily slid upward. Figure 8 shows the state after tightening.

るという著効を奏する。 As described above, according to the coupling band according to the present invention, both ends of the steel strip can easily slide on the plate, and both ends of the steel strip are bent outward, so that when the above-mentioned sliding occurs, It is possible to crush both ends of the fastening fittings with a relatively light force without getting caught, and the object to be fastened can be tightened uniformly with a strong force over the entire circumference, and there is no damage to the inner surface of the steel strip. Since there are no through holes or protrusions, there is no damage to the outer surface of the object to be fastened, and furthermore, when tightening, the bent pieces of the fastening fittings will not fit into the holes of the bent pieces, and the bent ends of both ends of the steel strip will not fit into the holes of the bent pieces. Since it can be deformed in the direction of further embedding, it can be tightened reliably without the drawbacks of conventional fastening fittings, such as the cut-out piece deforming and coming off from the hole in the steel band. After tightening, the tip of the bent piece of the tightening fitting becomes wedged into the outer wall of the steel band, and a strong frictional force acts between the two, effectively spreading the bent piece as a reaction to the tightening. This has the remarkable effect of preventing this and providing high tightening force.
