[0009]

A plate member 5 is formed on a fastening band 10, and this plate member 5 is provided with a concave groove 51 at the center side to reach both end edges, and the concave groove 51 is attached to the convex thread 2 of the hose 1. Then, the head side band 41 and the free side band 42 are joined to the flat portions 52 formed on both sides of the concave groove 51 of the plate material 5 and the respective bands are fixed in parallel, so that the bands are directly pressed onto the hose surface. can do.

Further, the head side band 41 and the free side band 42 are formed by using the two plate members 5 to form a flat portion 52 of the plate member 5.
And by making the width of the concave groove 51 of the plate member 5 smaller than the width of the convex spiral 2,
It can be used stably without shifting up and down.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a fastening band having a basic configuration according to the present invention. FIG. 2 is an explanatory view showing a fastening state of the fastening band, and is an explanatory view in the case where a plate material is attached to a convex spiral. FIG. 3 is an explanatory view showing a fastening state of the fastening body in FIG. FIG. 4 is a plan view showing an open state of the fastener,
It is principal part explanatory drawing of a fastening body. FIG. 5 is a side view when the fastening body is opened.

The fastening band 10 includes a head-side band 41, a free-side band 42, a fastening body 3 attached to an end of the head-side band 41, and a plate member 5. The plate member 5 is provided with a concave groove 51 to be attached to the hose 1 with a convex thread so as to reach both ends at the center side, and flat portions 52 are formed on both sides of the concave groove 51. The head side band 41 and the free side band 42 are joined and the respective bands are fixed in parallel.

Further, the plate member 5 is placed at a predetermined distance
At the same time, the width of the concave groove 51 of the plate member 5 is formed to be smaller than the width of the convex ridge line 2.

The head side and free side bands 41,
Reference numeral 42 denotes each of the circumferentially wound hoses 1 with the ridged spirals, and fastening of the free-side bands 42 to the fasteners 3 provided at the ends of the head-side bands 41 at portions where the spirals 2 do not exist. The hose 1 and the pipe 6 are bound.

After the free side band 42 is inserted through the fastening body 3, the bearing part 32 is
, And the locking portion 33 presses and locks the tooth mold 43 formed on the free side band 42 to enable the fastening. The release of the fastening state is made possible by opening the bearing portion 32.

[0016]

According to the present invention, in a fastening band in which a fastening body is fixed to one end and the other end is fastened to the fastening body, a center portion of the band is divided to be free from a head side band. Forming a side plate, forming a plate material provided with a concave groove to be attached to the hose with a convex spiral line so as to reach both ends at the center side, and flat portions formed on both sides of the concave groove of the plate material The head side band and the free side band are joined to each other and the respective bands are fixed in parallel, so that when these are bound to the hose, the fastening band directly contacts the hose and presses it. The fastening force is evenly distributed on the peripheral surface of the hose, and stable fastening can be performed.

[0017] Further, the present invention is characterized in that two plate members are joined at a predetermined interval, and the width of the concave groove of the plate member is made smaller than the width of the projecting spiral. It is possible to prevent the displacement of the fastening band.

Further, according to the present invention, a tooth form is formed at a free end of the free side band, and the tooth form of the free end of the inserted free side band is pressed and locked on the fastening body of the head side band. By providing the worm-shaped locking portion, the removal can be easily performed.
