Description

[Detailed description of the invention] This invention relates to a coupling band, and more specifically,
This is an extremely easy-to-manufacture bonding band, and even though it is a separate type bonding band, it can be firmly fastened by pulling the tightening margin sufficiently during assembly, similar to the lever-equipped coupling band of the palm type. Regarding the band.

Conventionally, a belt-shaped member was formed into a ring shape as a band used when connecting a rubber tube, etc. to a pipe, and the palms were joined at one end, and a high-rigidity lever was fixed to this palm-joining part in the middle. Bonding bands are known. In this case, by rotating the lever, the lever acts as a lever and reduces the diameter of the band member, so sufficient tightening force can be obtained, but it is necessary to use the coupling band by covering it from the outside of the object to be fastened. It cannot be used in some places, and
The disadvantage is that the processing process is complicated and the cost is very high.

On the other hand, so-called split type binding bands have the advantage of being able to be used by covering the object from the outside, but they have poor tightening workability and require lever locking like the palm-to-hand type. There is a problem in that the tightening work cannot be completed almost with one touch by devising the metal fittings, and the tightening force is relatively poor.

This idea was made in view of the above points,
The purpose of this is to bend one end of the band-like member and bend the other end of the band-like member in the opposite direction to the one end of the band-like member. To provide a coupling band in which bent portions at one end and the other end are engageable, and bent portions for fasteners are protruded from both sides of the band-like member in proximity to one end of the band-like member.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the front view of the coupling band 10 in the unattached state shown in FIG. 1, the left end of the steel strip member 12 extending horizontally in the left-right direction is bent vertically downward or inwardly at an angle of about 60 degrees by several mm to form a protruding part. 14 is formed, and the right end of the band-like member 12 is bent vertically upward by several millimeters to form a standing portion 16. Rectangular bent portions 18, 18 are protruded substantially horizontally from the right end of the band member 12 on the front side and back side of the band member 12 in the front-rear direction in the figure.

In order to assemble and fasten objects using the coupling band 10 having the above configuration, as shown in FIG. The bent portions 18, 18 of are brought into close contact with the outer circumferential surface of the rubber tube 20, and the standing portion 16 at the right end of the band member 12 is made to stand up on the outer circumference of the rubber tube 20. Next, the left end of the band-like member 12 is made to go around the rubber tube 20 in the direction of rotation of the hour hand, and
The left end surface, which is the inner end surface of the protrusion 14, is engaged with the right end surface of the protrusion 6 from above. Furthermore, the engagement portion between the upright portion 16 and the protruding portion 14 is crushed by hitting with a hammer from the upper left diagonally, but during this crushing, the lower end of the protruding portion 14 pushes the lower edge of the upright portion 16 to the left, Since the upper end of the standing portion 16 pushes the upper portion of the protruding portion 14 to the right, the tightening margin in the connecting band is drawn, and the fastening is completed by a strong fastening force by the hammer blow. In this state, the engagement shape between the upright portion 16 and the protruding portion 14 is a V-shape in which they are pressed against each other, and it can be used as is, but in order to ensure this engaged and locked state, the bent portion 18 is The rubber tube 20 is raised from the upper surface and crushed with a hammer to be used as a regular mouth-shaped fastener. In this case, not only is the locking secure, but since the bent portion 18 itself is located at the same level as the band member 12, the coupling band 10 does not rise up or become insufficiently tightened at the fastener portion, and the fastener It is also possible to eliminate the complexity of manufacturing by separately supplying, cutting, position fixing, spot welding, etc. the parts for use. Further, when such a bent portion 18 is not used, spot welding, welding, etc. can be suitably used.

To give another example, as a detent after engagement and locking, a mouth-shaped stopper 22 is formed in advance and inserted into the band member 12, so that this stopper 22 is engaged and locked. It can be fixed by sliding it onto the top. Furthermore, after inserting the tongue piece 24 that welds and extends to the upper surface of the engagement locking part into the mouth-shaped stopper 22 that has been fixed in advance to the band member 12, it is folded upward and fixed to the upper surface of the stopper 22. By doing so, it is possible to meet the requirements in cases where a sufficient detent is required in terms of strength.

In this way, the present invention is much easier to manufacture than a palm-type binding band because it simply involves cutting a single band-shaped member and bending both ends in opposite directions, simplifying the manufacturing process. can be used to reduce costs. In addition, since it is a split type connecting band, it can be used in areas with reduced diameters where palm-to-hand type connecting bands cannot be used. A strong diameter reduction force acts to complete a strong connection, which is a remarkable effect not found in conventional separation-type coupling bands.
In addition, the binding band can be fixed even more firmly by crushing and fixing the bent portions after the bent portions are hammered and fastened.

Although various explanations have been given above with reference to preferred embodiments of the present invention, it goes without saying that the present invention is not limited to the above-mentioned embodiments. Of course, modifications can be made.

Claims (1)

[Scope of utility model registration request] One end of the band-shaped member is bent, and the other end of the band-shaped member is bent in the opposite direction to the one end of the band-shaped member, while the one end and the other end are bent when the band-shaped member is wrapped around an object to be fastened. What is claimed is: 1. A coupling band characterized in that a bent part for a fastener protrudes from both sides of the band-shaped member in the vicinity of one end of the band-shaped member.
