Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improved binding band for smoothly and firmly binding a wire harness for electric wiring and the like.

[Conventional technology]

FIG. 5 is a perspective view showing a conventional binding band, and FIG. 6 is a perspective view showing a state in which the wire harness 7 is bound, for locking one surface of the strip 1 made of a flexible synthetic resin material. The serrated projections 2 are provided in series, and a locking tool 6 having a flexible locking claw 5 that engages with the locking serrated projection 2 in one end of the strip 1 in the strip lead-out hole 4. Are provided integrally.

That is, in order to bind the wire harness 7, the tip end 10 of the strip is inserted into the strip lead-out hole 4 of the locking tool 6, and the strip portion shown in FIG. When the piece 1 is pulled while swinging vertically (B and C directions) with respect to the longitudinal direction, the tip 5a of the locking claw 5 engages with the short side portion 8 of the locking sawtooth projection 2 as shown in FIG. The binding band 1 is prevented from coming out, and the binding band is held in a tightened state.

However, here, in the swing pulling in the C direction in FIG. 6, the binding band slides on the wire harness outer periphery 7a and the locking tool 6 which is the fulcrum for tightening rotates in the C direction, and the tightening is further tightened. Therefore, every time the rocking is repeated, the position of the locking tool 6 shifts to the back side where the workability is poor, which causes a problem that further tightening cannot be achieved.

That is, in FIG. 8, when the strip 1 is pulled in the direction B, the tip 8a of the short side portion of the locking sawtooth projection 2 comes into contact with the wire harness 7 at a substantially right angle and bites into the outer periphery 7a of the wire harness. However, when it is pulled in the opposite direction (C direction), the long side tip 9a slides on the outer surface 7a of the wire harness at a gentle angle, so that the sliding force does not act. It ends up.

Therefore, the binding work is not smooth, and the binding force is insufficient, which causes binding failure.

[Problems to be solved by the device]

The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide a binding band that can be bound smoothly and firmly in binding work of a wire harness or the like.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention has a serrated projection for locking, which is continuously provided on the fastening surface side of a flexible strip and is provided in a strip lead-out hole provided at the proximal end of the strip. In a binding band provided with a locking claw for the locking saw tooth projection, a tooth cutting is performed in a direction opposite to the locking saw tooth projection on the tightening surface side of the strip provided with the locking saw tooth projection. The structure is provided with a serrated projection for preventing slippage.

[Action]

In order to bind the wire harness 7 and the like with the binding band having the above configuration, the tip 10 of the strip 1 is inserted into the strip lead-out hole 4 and pulled while swinging vertically with respect to the longitudinal direction of the strip. The locking saw tooth projection 2 or the anti-slip saw tooth projection 3 provided in the opposite direction to the locking saw tooth projection exerts a drag force on the outer periphery 7a of the wire harness 7 or the like, so that the binding band slides. Therefore, the wire harness 7 or the like can be tightened smoothly and firmly without changing the position of the strip lead-out hole 4, and the state is held by engaging the locking serrations 2 with the locking claws 5. You can

〔Example〕

FIG. 1 is a perspective view showing a binding band according to the present invention. A locking sawtooth projection 2 similar to the conventional one is continuously provided near the center of one surface of a strip 1 made of a flexible synthetic resin material. At the same time, anti-slip saw-tooth projections 3 are provided in parallel with the lock saw-tooth projections 2 in opposite directions to the lock saw-tooth projections 2 on both sides of the surface.

The anti-slip serrated projections 3 are set to have the same number and the same height as the locking serrated projections 2 and the widths a of the projections provided on both sides are adjusted to be substantially the same width as the locking serrated projection 2. As described later, the difficulty in slipping is substantially the same with respect to the swinging directions B and C at the time of binding the wire harness shown in FIG.

A locking tool 6 is integrally provided at one end of the strip 1 as in the conventional case, and a flexible locking claw 5 is provided on the lower side of the locking tool 6 inside the strip lead-out hole 4 and has a saw blade for locking. The protrusion 2 is slightly narrower than the protrusion 2.

Incidentally, the shape of the anti-slip saw tooth projections 3 is not necessarily the dimension of the short side portion 8 and the long side portion 9 or the height such that the shape of the locking saw tooth projections 2 is reversed on one surface of the strip 1. It does not have to be the same as the saw-toothed projection 2, and the point is that the projection shape is such that the effect of preventing slippage can be obtained.

FIG. 2 is a front view showing a state in which the strip 1 is inserted into the strip lead-out hole 4 and the wire harness 7 is bound, and when the binding band is pulled in the direction B in the drawing, the locking sawtooth projection 2 is formed.
Exerts a drag force against the slip and suppresses the slip, and the serrations 3 for preventing slip have the same action in the C direction, so that the wire harness can be smoothly tightened without the locking tool 6 moving. .

Then, as shown in FIGS. 3 and 4, the strip lead-out direction (D
Direction), the long side portion 9 of the sawtooth-like projection 2 for locking is slidably contacted with the lock claw 5 and bends the lock claw 5 downward to enter, but locks in the opposite (E) direction, that is, the loosening direction. The short side portion 8 of the saw-toothed projection 2 comes into contact with the tip 5a of the lock claw to prevent the binding band from loosening.

[Effect of device]

According to the present invention, as described above, the anti-slip saw tooth projection, which is cut in the opposite direction to the locking saw tooth projection, is provided on the tightening surface side where the locking saw tooth projection is provided. The serrated projections and the anti-slip serrated projections exert anti-slip force in the rotating directions opposite to each other with respect to the wire harness, etc., so that the wire harness etc. can be smoothly and firmly bound, and the binding of the wire harness etc. This has the effect of improving workability and eliminating binding defects.
