DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a band fastener according to the present invention will be described based on a specific embodiment shown in the drawings.
[0009]
FIG. 1 is a front view showing an embodiment of a band fastener according to the present invention, FIG. 2 is a cross-sectional plan view thereof, FIG. 3 is a cross-sectional plan view in a state where an operation lever is opened, and FIG. It is line sectional drawing. In the figure, reference numeral 1 denotes a fastener body, and in this embodiment, the body 1 is formed of a synthetic resin in a substantially U-shaped longitudinal section as shown in FIG. On the bottom surface, band locking holes 10a and 10b for locking one end of the band are provided.
[0010]
In the figure, reference numeral 2 denotes an operating lever for fastening the band. In the present embodiment, the lever 2 is formed in a substantially tongue-like shape from a synthetic resin, and protrudes laterally on both sides of the base 2a of the lever 2. The shaft portion 21 is provided integrally. The operating lever 2 is connected to the main body 1 so as to be able to be tilted by fitting the shaft portion 21 into bearing holes 11 formed on both upper and lower side surfaces of the main body 1.
[0011]
A band insertion hole 22 is formed in the base 2a of the operation lever 2, and a guide hole 12 for inserting the band through the band insertion hole 22 is provided at the right end of the main body 1 in the vicinity of the base 2a. Yes. As shown in FIG. 3, the guide hole 12 and the band insertion hole 22 are configured to match each other and continuously communicate with each other when the operating lever 2 is raised outside the main body 1.
Further, locking projections 23 are integrally provided on both side portions on the free end side of the operating lever 2, and the operating lever 2 is engaged by engaging the locking projections 23 with locking holes 13 provided on the main body side. It is the structure locked by rotation prevention.
[0013]
In the above configuration, in order to attach various articles to the utility pole P, for example, when a band, for example, a synthetic resin band B, is fastened and fixed to the peripheral surface of the utility pole P, first, as shown in FIG. With the operating lever 2 raised to the outside of the main body 1, the main body 1 is disposed on the peripheral surface of the utility pole P, and one end B1 of the band B hung around the peripheral surface of the utility pole P is used as a band locking hole of the main body 1. 10a and 10b are inserted as shown, and the band end B1 is sandwiched between the main body 1 and the utility pole P and fixed.
[0014]
Next, the other end B2 of the band B is inserted into the band insertion hole 22 of the operation lever 2. At this time, the guide hole 12 is provided in the fastening tool body 1 as described above, and the operation lever 2 is moved as shown in FIG. As shown in (a), the guide hole 12 and the band insertion hole 22 are in communication with each other when the guide hole 12 and the band insertion hole 22 are in communication with each other. The band B can be easily inserted into the insertion hole 22 at the same time.
[0015]
Next, when the operating lever is rotated in the direction of arrow a in FIG. 5A with the band other end B2 inserted into the band insertion hole 22 as described above, the band inserted through the band insertion hole 22 and the like. The end B2 is gradually drawn in the direction of the arrow b while being bent in a substantially Z shape so as to stick to the base 2a of the operation lever 2 as shown in FIG. When the operating lever is further rotated in the direction of arrow a and pushed into the main body 1 as shown in FIG. 3C, the other end B2 of the band is further wound around the base 2a of the operating lever 2 and pulled. Thus, the band B can be tightened and fixed in a tension state by engaging the locking projection 23 of the operating lever 2 with the locking hole 13 of the main body 1.
[0016]
In the state of being tightened as described above, the band other end B2 is bent and wound around the base 2a of the operation lever 2 in a substantially Z shape, so that there is no risk of unintentional loosening. Further, since the band other end B2 is inserted into the band insertion hole 22 of the insertion lever 2 through the guide hole 12 on the main body side, the reaction force due to the tension of the band B causes the reaction force from the main body 1 in FIG. In the figure, when the right band end is pulled rightward, the pulling force acts on the Z-shaped bent portion through the contact portion with the guide hole 12, and a large force is directly applied to the bent portion. Since it is not hung, the bent portion is not damaged or broken even when a synthetic resin band is used. Further, the band other end B2 is inserted into the band insertion hole 22 through the guide hole 12, so that the band B does not greatly protrude outward after the band is tightened, and does not interfere with the band B. As a result, the band does not loosen.
[0017]
In addition, the base of the operation lever 2 is provided with a protrusion 24 as shown in the drawing, that is, as shown in FIG. 2, and when the band is tightened, as shown in FIG. The band B may be sandwiched between the bottom surface of the main body 1. By doing so, the band B can be more reliably fixed. Further, as shown in the illustrated example, the protruding portion 24 may be formed with an anti-slip ridge 24a in a direction perpendicular to the rotation direction (tilting direction) of the lever 2, so that the band is prevented from slipping. Furthermore, it becomes possible to fix reliably.
[0018]
【The invention's effect】
As described above, the band fastener according to the present invention has the guide hole 12 when the band B is inserted into the band insertion hole 22 provided in the operation lever 2 in the fastener body 1 near the base of the operation lever 2. Since the band insertion hole 22 is continuously communicated with the guide hole 12 when the operating lever 2 is raised outside the fastener body 1, the band B having one end B1 connected to the body 1 is provided. When the other end B <b> 2 is inserted into the band insertion hole 22 of the operation lever 2, the band B can be easily inserted into the band insertion hole 22 simply by passing the band through the guide hole 12. In addition, since the band other end B2 is passed through the band insertion hole 22 through the guide hole 12 on the main body side, the reaction force at the time of band tightening is directly applied to the vicinity of the insertion part to the band insertion hole 22 as described above. It is possible to prevent damage or breakage due to the action, and the band B can be prevented from protruding out of the way and obstructing the band, thereby preventing the band from loosening. It is possible to provide a good band fastener.
