DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band fastener mainly used when an object such as a signboard is wound around a column such as a telephone pole using a band. is there.

[0002]

2. Description of the Related Art As means for fixing an object to be mounted such as a sign board on the outer peripheral surface of a pillar such as a telephone pole, a means generally used conventionally is a stainless steel wound around a pillar from the surface of the object to be mounted. A metal band having a pair of male and female engaging members, such as a shrimp, is pulled and latched at both ends of a band made of metal. In other words, the band wound around the column is pulled up and tightened, and in the tightened state, the male and female pair of engagement fittings are pivotally operated to a position beyond the conceivable point (dead point) so as to be latched and fixed.

[0003] However, in the conventional general fixing means as described above, it is necessary to rotate the engagement fitting with a large force sufficient to resist a reaction force when the other end of the band is pulled. It requires labor and lacks in operability.Moreover, since both the band and the engagement bracket are made of metal, they are easily injured by slipping of the hand when a large operation force is applied during work, and even after fixing. There is a problem that it is easily touched and injured.

Therefore, the present applicant has adopted the above-mentioned band as
Along with using a resin band in which a number of protrusions are formed at predetermined intervals in the longitudinal direction, an attempt was made to use a resin band fastener instead of the pair of engagement fittings, and as a result, for example, As disclosed in Japanese Utility Model Publication No. 8-3288, the function of connecting one end of the resin band and the function of engaging with the protrusion at the other end of the resin band wound around the outer peripheral surface of the pillar body. A resin band fastener having a dovetail and capable of exhibiting and maintaining a tightening function in a state where the engaging claw is engaged with the projection of the band has been proposed.
As a result, the problem of the conventional general fixing means using the metal band and the metal fitting has been successfully solved.

[0005]

However, in the resin band fastener proposed by the present applicant and disclosed in Japanese Utility Model Publication No. 8-3288, the other end of the resin band is connected to the other end of the resin band. Since it was configured so as to be inserted into the hole formed in the resin base of the fastener as a single piece and to engage the engaging claw with the projection on the other end side of the inserted band, it was wound around the column. When the band is strongly tightened, a strong pulling force is applied to the band, and the engagement between the engaging claw and the projection is not released, but the band itself grows and gradually becomes thinner and eventually breaks there is a possibility.

Therefore, in order to increase the tensile strength of the band itself, it is conceivable to use a resin band in which a reinforcing core wire is buried along the longitudinal direction within the wall thickness. While the adhesive strength of the resin layer is high and both work together, it keeps high tensile strength and does not break, but if the core wire shifts and moves in the resin layer due to the strong tensile force, the adhesive strength of both decreases, The core wire gradually comes off, and as a result, the tensile strength of the band as a whole becomes smaller than the tensile strength of the resin layer. In this case, there is a problem that the resin layer expands and thin and thin breaks occur. It had been.

[0007] The present invention has been made in view of the above-described circumstances, and not only can ensure operability and safety during work, but also do not cause unexpected breakage of the band even in a strongly tightened state.
