  In Patent Document 1, the band portion extends from the inlet end of the buckle portion. When the cord body is bound by the binding band of such structure, the block-like buckle portion inevitably protrudes outward of the ring formed by the binding band. In this case, it is not possible to use the binding band in a narrow place because it is necessary to secure an extra space for binding. Or, in order to bind with a binding band, it is necessary to route to a route with a relatively large space, and the routing route is restricted.

  This problem is particularly pronounced in the case of bundling through a frame disposed in a state of being attached to the cord such as a protector for protecting the cord or a fixing bracket. Specifically, as shown in FIG. 10, when the cord W is bound by the conventional binding band 100 as in Patent Document 1 via the frame 30, a frame between the band 110 and the cord W Since the main body wall portion 31 of 30 intervenes, a large dead space is generated between the buckle portion 120 and the rope body W. FIG. 10 shows the band insertion hole 35 formed in the frame 30 with the band 110 inserted and bound, the reference numeral 32 is an outer wall defining the band insertion hole 35, and the reference numeral 34 is It is a guide wall for guiding the band portion 110.

  Then, this invention solves the said subject, and it aims at providing the binding band which can space-saving-ize in the state which tied the rope body.

  As means for that purpose, the present invention relates to a binding band for binding a rope, comprising a long band part wound around the cord, and a buckle part for inserting and locking the band. Have. The buckle portion is provided at a proximal end of the band portion. A serrated serrate is provided on one surface of the band portion. The buckle portion has a through hole including an inlet and an outlet for inserting the band portion, and an engagement claw provided in the through hole and engaged with the serration to lock the band portion. . In addition, the band portion extends from the outlet end of the buckle portion such that the inlet of the buckle portion and the serration are in the same direction.

  If the buckle inlet and serration are oriented in the same direction, and the band extends from the buckle outlet end, the circle formed by the tie when the cord is tied by the tie. It protrudes inward of the ring. In other words, the buckle portion does not protrude outward of the ring formed by the binding band. Thereby, space saving can be achieved in the state which bound a rope body by a binding band. In particular, in the case of binding the rope through the frame, since the buckle part is accommodated in the dead space which has conventionally occurred between the rope and the buckle part, the space utilization efficiency is high, It is possible to make the most of the space saving effect.

  Preferably, the side surface of the buckle portion is a tapered surface that tapers from the outlet to the inlet. As a result, the buckle portion can be easily accommodated inside the annular ring formed by the binding band, so that space saving can be further achieved. In particular, in the case of tying the rope through the frame, the buckle can be neatly contained in the conventional dead space, and the distance between the rope and the buckle can be made as small as possible, so that the space utilization efficiency becomes higher. .

  Further, in the band insertion hole surrounded by the main body wall of the frame, a pair of side walls protruding from the main body wall, and an outer wall bridged to the ends of both side walls, the binding is performed When the rope is bound through the band, in the bound state, the buckle portion is in contact with the main body wall surrounding the band insertion hole and is not in contact with the outer wall portion. Thus, the cords can be compactly bound.

  It is preferable to provide the protrusion which contact | abuts with the said outer wall part in the state which tied the said binding band through the said band penetration hole, and is bound on the other surface of the said band part. Thus, in a state where the rope is bound through the frame, the protrusion abuts against the outer wall and functions as a stopper, so that the binding band idles in a direction in which the buckle separates from the main body wall of the frame It is prevented that the band rotates idle relative to the frame and the cord. In the reverse direction, the buckle portion is in contact with the main body wall of the frame so that it does not slip. Thereby, a cord body can be bound stably.

  ADVANTAGE OF THE INVENTION According to the binding band of this invention, space saving can be achieved rather than before in the state which bound rope bodies, such as a wire harness. In particular, in the case of tying the rope through the frame, the use of the space is high and space saving is more efficient because the buckle is contained in the dead space that conventionally occurred between the buckle and the rope. Can be implemented.

  Hereinafter, representative embodiments of the present invention will be described. As shown in FIGS. 1 to 5, the binding band 1 of the present embodiment has a long belt-like band portion 10 and a buckle portion 20 provided at the base end of the band portion 10. The binding band 1 is an injection-molded article made of synthetic resin, and the band portion 10 and the buckle portion 20 are integrally and directly continuous, and other portions or members are provided between the band portion 10 and the buckle portion 20 Does not exist.

  The band portion 10 is a flexible portion which is wound around the cable from the outside, and the serrations 11 are provided on one surface, and the protrusions 12 are provided on the other surface. The serrations 11 are formed by arranging a plurality of sawtooth-shaped irregularities extending in the width direction of the band portion 10 in the longitudinal direction. The serrations 11 are provided in the longitudinal direction of the band portion 10 from the proximal end portion to the central portion and slightly to the distal end portion. In addition, the serrations 11 are provided at the center in the width direction of the band portion 10. The length (formation range) of the band portion 10 and the serration 11 is sufficiently longer than the outer peripheral length of the cord W, as well as the length necessary for winding the cord W around the frame 30 described later.

  On both side edges of one surface of the tip end portion of the band portion 10, a plurality of small protrusions 13 are arranged in parallel at predetermined intervals in the longitudinal direction. The presence of the small projections 13 makes it easy to hold the tip of the band portion 10 by hand and perform the winding operation (in particular, the pulling operation) of the binding band 1. The tip portion of the band portion 10 is thinner than the other portions, and the top portion of the small projection 13 is flush with the other portion of the band portion 10. As a result, the small projections 13 can be smoothly wound on the binding band 1 without being caught in the through holes 21 of the buckle portion 20 described later, the band insertion holes 35 of the frame 30, and the like.

  The projections 12 provided on the other surface of the band portion 10 are provided at the center in the width direction of the base end portion of the band portion 10, and are formed in a triangle or a trapezoid in a side view. That is, both longitudinal side surfaces of the projection 12 are inclined surfaces. The height of the projection 12 (the thickness of the band portion 10 including the top portion of the projection 12) is larger than the opening thickness of the band insertion hole 35 of the frame 30 described later.

  The buckle portion 20 is a block having a through hole 21 inside, and is a portion for inserting the band portion 10 into the through hole 21 and locking it. The through hole 21 is formed so as to extend from an inlet 21 a opened on one surface of the buckle portion 20 to an outlet 21 b opened on the other surface of the buckle portion 20. The inlet 21 a of the through hole 21 and the serration 11 of the band 10 are in the same direction. Further, inside the through hole 21, an engagement claw 22 that engages with the serration 11 of the band portion 10 is provided. In addition, the band portion 10 extends from the outlet end of the buckle portion 20 (the end edge of the surface on which the outlet 21 b of the through hole 21 is formed).

  Further, a band cover 23 is provided on the other surface of the buckle portion 20 so as to surround the outlet 21 a of the through hole 21. The band cover 23 is formed in a pair so as to face each other from the side edges of the outlet 21a of the through hole 21 and a groove 23a is formed in a recess on both opposing surfaces. The width and thickness of the groove 23 a are formed to be sized to accommodate the buckle portion 10.

  The side surface (peripheral surface) of the buckle portion 20 is a tapered surface that tapers from the surface on which the outlet 21 b of the through hole 21 is formed to the surface on which the inlet 21 a is formed. In addition, on the side surface of the buckle portion 20, no other member or portion is provided.

  The bundling band 1 is for bundling a plurality of cords W together and bundling them, or for stably fixing an intermediate portion of the cords W arranged by a predetermined route at a predetermined place, etc. used. The rope body W is not particularly limited as long as it is a long string. Specifically, wire harnesses, cables, robes, cords and the like can be mentioned. In addition, there are no particular restrictions on the location of cable body W, and various vehicles such as cars, ships, trains, and aircraft, equipments such as industrial machines, machine tools, electronic devices, various plants, power stations, substations, etc. It will be distributed at facilities etc.

  Further, as shown in FIGS. 6 to 7, the rope body W may be provided with a frame body 30 such as a protector for preventing damage due to impact or the like, or a bracket for fixing to a predetermined place. . In this case, a band portion insertion hole 35 is formed in the frame 30, and after the band portion 10 is inserted into the band portion insertion hole 35, the cord W is bound. The band insertion hole 35 is formed by the main body wall 31 of the frame 30, the pair of side walls 33 protruding from the main body wall 31, and the outer wall 32 bridged to the ends of the both side walls 33. It will be enclosed.

  The frame 30 is a synthetic resin injection-molded product, and has various shapes depending on the application and the installation place, etc. The main body wall 31 following the rope W is formed in an L-shaped cross section. Further, in the present embodiment shown in FIGS. 6 and 7, the guide wall 34 is formed along the winding route of the band portion 10 from the both side wall portions 33 of the band insertion hole 35.

  Next, the procedure of tying the rope body W by the tying band 1 through the frame 30 will be described. First, in a direction in which the serrations 11 face the frame W, the band portion 10 is inserted from the tip into the band portion insertion hole 35. At this time, since a plurality of small projections 13 are formed at the tip of the band portion 10, the band portion 10 is easily grasped and pulled by hand. When the band portion 10 is inserted as it is, the protrusion 12 abuts on the outer wall portion 32 of the band portion insertion hole 35. Therefore, the projections 12 and the outer wall portion 32 are elastically deformed and the band portion 10 is strongly pulled until the projections 12 exceed the outer wall portion 32. At this time, since the side surface of the protrusion 12 is a gentle inclined surface, the protrusion 12 easily passes over the outer wall portion 32. On the other hand, since the small projections 13 at the tip of the band 10 are within the range of the thickness of the band 10, the small projections 13 are not caught on the periphery of the band insertion hole 35 or the like during the insertion operation.

  Subsequently, the band portion 10 is inserted to the proximal end until the buckle portion 20 abuts on the periphery of the band portion insertion hole 35. Then, the band 10 is inserted into the through hole 21 of the buckle 20 by making the outside of the cord W go around in a state where the band 10 is wound between the guide walls 34. Then, since the serrations 11 and the engagement claws 22 engage with each other, the band portion 10 is pulled more strongly to tightly lock the band portion 10 to the rope W. In this state, a portion unnecessary for binding including the tip of the band portion 10 extends from the outlet 21 b of the buckle portion 20, so the portion unnecessary for binding is cut. At this time, in the case where the cut surface of the band portion 10 has a distorted shape or the peripheral edge of the cut surface has an acute angle, if the cut surface is exposed to the outside, there is a danger to human beings. However, in the present embodiment, since the band cover 23 covers the portion of the band 10 extending from the outlet 21 b of the through hole 21 including the cut surface of the band 10, there is no harm to people.

  Further, the band portion 10 extends from the outlet end of the buckle portion 20 so that the block-like buckle portion 20 is inside the ring formed by the binding band 1. Moreover, the side surface of the buckle portion 20 is a tapered surface, and the buckle portion 20 is in contact with the main body wall portion 31 surrounding the band insertion hole 35 in the state where the rope W is bound. Is not in contact. Thereby, useless dead space does not arise between the buckle part 20 and the rope body W, and it can bind compactly.

  Moreover, the binding band 1 does not idle relatively to the frame 30 or the rope W by the projection 12 contacting the outer wall 32 surrounding the band insertion hole 35 and functioning as a stopper. Furthermore, since the band portion 10 is guided by the guide wall 34, the binding position is also stable.

  Although the representative embodiments of the present invention have been described above, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention. For example, as shown in FIG. 8, the protrusions 12 are not necessarily required. In addition, as shown in FIG. 9, the rope W can be tied directly by the binding band 1 without using the frame 30. The side surface of the buckle portion 20 may not necessarily be a tapered surface.

  In the above embodiment, both longitudinal side surfaces of the projection 12 are inclined surfaces having the same angle, but the side surface on the base end side is preferably a steep slope, and most preferably a plane perpendicular to the band portion 10. Thereby, in a state where the rope W is bound by the binding band 1, the stopper function when the protrusion 12 abuts on the outer wall portion 32 of the frame 30 is enhanced. On the other hand, the side surface on the tip end side of the projection 12 is preferably a gentle slope as much as possible. When the band portion 10 is inserted into the band insertion hole 35, the protrusion 12 easily passes over the outer wall portion 32 of the frame 30.
