Description

  The present invention relates to a binding band that is wound around an outer periphery of a binding object to bind the binding object.

A binding band that binds electric wires, pipes, wires, harnesses, and the like has a wide range of applications, and is also used as a so-called pipe band for fixing pipes and connecting pipes.
This binding band usually has a long band in the longitudinal direction and a fastener for inserting and fastening one end of the band. In a generally used binding band, one end of the band is inserted from the lower surface side of the fastener (that is, inserted from a direction perpendicular to the longitudinal direction of the band near the fastener) (for example, Patent Document 1). (See FIG. 3). In the case of the prior art as shown in Patent Document 1, a space is generated between the object to be bound (the object to be bound) and the band, and the binding becomes unstable because the object to be bound and the band do not adhere to each other. There was a problem with reliability easily.

  Moreover, what is inserted in the binding band from the direction along the longitudinal direction of the band near a fastener is examined (for example, patent document 2).

The inclined surface 51F of the main body band upper surface side tooth 51 and the right-angle surface 53T of the main body band lower surface tooth 53 are formed in parallel and have the same height dimension (distance between the upper end and the lower end, and so on). have. The main body band upper surface side teeth 51 are not formed on the entire upper surface of the main body band portion 50, but are formed only in the vicinity of the fastener 30, but the main body band portion 50 is wound around the penetrating portion 90. It may be formed on the upper surface of the main body band unit 50 excluding the vicinity of the tip inserted into the main body. As a result, the object 40 having a small diameter can be bundled, and the meshing region between the main body band lower surface side tooth 53 and the auxiliary band upper surface side tooth 71, the main body band lower surface side tooth 53, and the main body band upper surface side tooth 51. The engagement area can be lengthened.

The auxiliary band portion 70 is formed to have a shorter distance in the longitudinal direction than the main body band portion 50. The width of the auxiliary band portion 70 according to the present embodiment is formed to be the same as the width of the main body band portion 50. On the free end side of the auxiliary band portion 70, an auxiliary band taper portion 72 is formed which gradually decreases in width and thickness as it reaches the tip end side. The auxiliary band taper portion 72 is tapered toward the tip and formed with a small thickness, so that when the tip side of the main body band portion 50 is overlapped with the upper surface, a gap is generated at the place where the main body band portion 50 rides. The tip side of the main body band unit 50 overlaps with a gentle curve.
In the vicinity of the fastener 30 on the upper surface of the auxiliary band portion 70, the auxiliary band upper surface side teeth that can be engaged with the main body band lower surface side teeth 53 when the main body band tip 55 is inserted into the penetration portion 90 from the insertion opening 96. 71 are lined up.

The auxiliary band upper surface side teeth 71 are composed of the inclined surface 71F described above and a right-angle surface 71T that descends in a substantially vertical direction from the upper end of the inclined surface 71F toward the upper surface side of the main body band portion 50. The inclined surface 71F of the auxiliary band upper surface side tooth 71 and the inclined surface 53B of the main body band lower surface side tooth 53 are formed in parallel and have the same length in the inclined direction. The right-angle surface 71T of the auxiliary band upper surface side tooth 71 and the right-angle surface 53T of the main body band lower surface side tooth 53 are formed in parallel and have the same height.

  In the binding band 10 according to the present embodiment, the main body band lower surface side teeth 53 and the auxiliary band upper surface side teeth 71 mesh with each other when the main body band tip portion 55 is inserted from the insertion opening 96 of the through portion 90, and the through portion When the main body band distal end portion 55 is pulled out from the pullout opening 97 of 90, the main body band lower surface side teeth 53 and the main body band upper surface base end side teeth 51 are engaged with each other. Thereby, it latches in these two places in total. In the present embodiment, only one fastener 30 is formed in the middle of one band 20, but the present invention is not limited to this, and two or more pieces in the longitudinal direction of the band 20 are used. The fastener 30 may be formed. When n fasteners 30 are provided, the entire binding band 10 is locked at a total of 2n points by being locked at two points as described above by one fastener 30. It will be.

  In the binding band 10 according to the present embodiment, the main body band distal end portion 55 is inserted along the longitudinal direction of the band 20 from the insertion opening portion 96 of the penetrating portion 90. Compared with the case where the main body band tip 55 is inserted in the direction perpendicular to the longitudinal direction of the band 20 from the back side of the fastener 30, the fastener 30 is in close contact with the outer surface of the object 40 Thus, the adhesiveness with the object to be bound 40 is improved. In addition, the fastener 30 itself can be part of a loop-shaped ring that binds the object to be bound 40 and can be brought into close contact with the outer surface of the object to be bound 40. The main body band tip 55 inserted from the insertion opening 96 of the penetrating portion 90 is pulled out from the pulling opening 97 of the penetrating portion 90 along the longitudinal direction of the band 20. As a result, the pulled-out main body band tip 55 also does not jump out in a direction protruding from the outer surface of the object 40 to be bundled, and is along the longitudinal direction of the main body band part 50 extending from the through-hole 90, that is, the object 40 It can arrange | position along the outer surface of. As a result, in the state after binding, the entire binding band 10 is in close contact with the outer surface of the object 40 to be bound, which is convenient for binding in a narrow space.

Further, when the main body band tip 55 is inserted from the insertion opening 96 of the penetrating portion 90, the main body band lower surface side tooth 53 and the auxiliary band upper surface side tooth 71 are engaged with each other. When the main body band distal end portion 55 is pulled out from the pull-out opening portion 97 of the penetrating portion 90, the main body band lower surface side tooth 53 and the main body band upper surface base end side tooth 51 are engaged with each other. The binding band 10 according to the present embodiment is locked at two places in total. As a result, the binding band 10 can be provided in a plurality as compared with the one having only the fastener 30, and the binding band 10 that is difficult to come off and improved in reliability can be provided.
For example, even if the locking state at one location disappears, the locking status at the other location is maintained, so that the overall locking status can be maintained. Further, by being locked at two locations, stress concentration is suppressed from being concentrated at one specific location, stress is dispersed, breakage is suppressed, and durability performance is improved as a result.

Furthermore, the binding band 10 according to the present embodiment is much more in front of and behind the fastener 30 than when the fastener 30 is locked by only one or several engagements at a specific location within a narrow range within the fastener 30. Locking is achieved by meshing a large number of teeth in a wide area. For this reason, the frictional resistance can be increased uniformly as a whole, and a stable locking state is maintained.
As a result, there is no instability in which the bundling state breaks due to the breakage of one or several teeth, and the bundling state is maintained in a stable state by a strong frictional resistance force due to the engagement of a large number of teeth in a wide range. Is done.

As shown in FIG. 2, the binding band 10 according to the present embodiment can be wound around and bundled in a state of being in close contact with the outer peripheral surface of the pipe other than the purpose of bundling a plurality of objects. It can also be used as a pipe band. As described above, the binding band 10 according to the present embodiment can be closely attached along the outer peripheral surface of the pipe as the object to be bound 40 without a gap.
(Second Embodiment)
As shown in FIGS. 3 and 4, the binding band 10 according to the present embodiment is formed at both side ends in the width direction (direction perpendicular to the longitudinal direction of the band 20) of the lower surfaces of the main body band unit 50 and the auxiliary band unit 70. Two ridges 60 projecting downward are formed along the longitudinal direction of the band 20 (see FIG. 4). Components similar to those in the first embodiment are given the same component names and component numbers, and description thereof is omitted. Hereinafter, differences from the contents of the first embodiment will be mainly described.

The ridge 60 has two main body band side ridges 61 projecting downward at both ends in the width direction of the lower surface of the main body band portion 50, and downward on both sides in the width direction of the lower surface of the auxiliary band portion 70. And two auxiliary band side ridges 62 projecting toward.
The main body band lower surface side teeth 53 are arranged between the main body band side protrusions 61 on both side ends thereof. The lower end of the main body band lower surface side tooth 53 is formed so as to be positioned above the lower surface of the main body band side protrusion 61. That is, the main body band lower surface side tooth 53 is formed at a position where it enters the space between the two main body band side protrusions 61.
The lower surface of the main body band side protrusion 61 and the lower surface of the auxiliary band side protrusion 62 are formed to be flush with each other when the binding band 10 is placed on a horizontal plane. Similarly, the lower surface of the fastener 30 portion is also formed to be flush with the lower surfaces of the main body band side protrusion 61 and the auxiliary band side protrusion 62. Specifically, an opening 31 is formed below the fastener 30 portion, and a fastener side plate lower surface 34, which is the lower surface of the fastener side plate 32, is formed on both sides of the opening 31. The fastener side plate lower surface 34 is a surface that comes into contact with the surface of the binding object 40 when the binding band 10 is wound around the binding object 40. When the binding band 10 is placed on a horizontal plane, the fastener side plate lower surface 34 is formed to be flush with the lower surfaces of the main body band side protrusion 61 and the auxiliary band side protrusion 62.

  Here, the lower surface of the main body band side ridge 61, the lower surface of the auxiliary band side ridge 62, and the fastener side plate lower surface 34 are not particularly shown, but the lower surface of the cross section in the direction perpendicular to the longitudinal direction of the binding band 10. The ridge line on the side is formed in a gentle arc shape that protrudes slightly convex downward. When these lower surfaces come into contact with the outer surface of the object to be bound 40, the entire surface of these lower surfaces does not contact the surface of the object to be bundled 40 (rather than being contacted face-to-face). By being in contact with each other, the contacted portion is formed so as to be on a line around the object 40 to be bound. When the surfaces are brought into contact with each other so that the contact area is face-to-face, a gap is generated between the surfaces due to the presence of slight irregularities on each surface. In the binding band 10 according to the present embodiment, the contact area with the surface of the object to be bound 40 is linear, so that a slight gap is not generated and the adhesion with the object to be bound 40 is improved. It is a thing.

The auxiliary band portion 70 is formed to have a strip shape having a width T slightly narrower than the width S between the inner side surfaces of the two main body band side protrusions 61 facing each other (see FIG. 4). The width T of the auxiliary band portion 70 is formed so as to have the same dimension as the width S between the inner side surfaces of the main body band side protrusion 61 if both can be elastically deformed when covered from above the auxiliary band portion 70. May be.
On the upper surface of the auxiliary band portion 70, auxiliary band upper surface side teeth 71 that can mesh with the main body band lower surface side teeth 53 are arranged in the same manner as described in the first embodiment.
On the upper surface in the vicinity of the fastener 30 of the main body band portion 50, stepped step portions 65 are formed along the longitudinal direction at both side ends in the width direction of the main body band portion 50 (see FIG. 4B). . The step portion 65 may be formed not only in the vicinity of the protrusion 60 of the main body band portion 50 but also over the entire length of the main body band portion 50. The width W between the outer side surfaces of the stepped portions 65 at both ends is formed to be slightly narrower than the width S between the inner side surfaces of the main body band side protrusion 61. In the case where the binding band 10 is easily elastically deformed, the width W between the outer surfaces of the stepped portion 65 may be formed to have the same dimension as the width S between the inner surfaces of the main body band side protrusion 61. Here, the width W between the outer surfaces of the stepped portion 65 and the width T of the auxiliary band portion 70 are formed to have the same dimensions.

In the vicinity of the fastener 30 on the upper surface between the step portions 65 of the main body band portion 50, main body band upper surface proximal end teeth 51 similar to those described in the first embodiment are arranged.
In the binding band 10 according to the present embodiment, when the main body band tip 55 is inserted from the insertion opening 96 of the penetrating portion 90, the front end of the main body band 50 is between the main band side protrusions 61 and the auxiliary band portion. It is formed to be slidable with the upper surface side (upper part) of 70 sandwiched therebetween. Furthermore, when the main body band tip 55 is pulled out from the pull-out opening 97 of the through-hole 90, the front end side of the main body band section 50 is located between the main body band side protrusions 61 on the lower surface of the main body band section 50. It is possible to slide with the stepped portion 65 on the upper surface sandwiched (see FIG. 4).

It is formed so that it can touch. If the entire lower surface of the band 20 is brought into contact with the object 40 to be bound by the surface, a portion having poor adhesion is generated due to unevenness on the surface of the object 40 to be bound. On the other hand, in the binding band 10 according to the present embodiment, the main body band-side ridge 61 and the auxiliary band-side ridge 62 protrude downward, and the elongated width on both ends of the band 20 rather than the entire surface of the band 20 Are in contact with the outer peripheral surface of the object to be bound 40 linearly in a narrow region (area). As a result, the band 20 has good followability with respect to the irregularities on the outer peripheral surface of the object 40 and the binding band 10 has improved adhesion to the outer surface of the object 40.

Further, in the binding band 10 according to the present embodiment, when the binding band 10 is placed on a horizontal plane, the fastener side plate lower surface 34 includes a lower surface of the auxiliary band side protrusion 62, and a lower surface of the auxiliary band side protrusion 62. It is formed so as to be flush with both. For this reason, from the main body band side ridge 61 to the auxiliary band side ridge 62, it is possible to bind the object 40 to be bound by the lines of the two ridges 60 that are continuous over the entire length of the band 20. As a result, it is possible to provide the binding band 10 that has excellent followability to the surface of the object to be bound 40 and good adhesion.

For example, even if any one of the locked states disappears, the remaining three locked states are maintained, so that the locked state as a whole is stably maintained. Further, by being locked at four places, it is possible to suppress the concentration of stress at one specific place, to further disperse the stress, to suppress breakage, and to further improve the durability performance.
In the penetrating portion 90 according to the present embodiment, both the penetrating portion lower teeth 91 and the pins 93 are in the locked state on both the upper and lower surfaces so that the lower surface and the upper surface on the front end side of the main body band portion 50 are sandwiched from above and below. Compared to a state in which the main body band portion 50 is locked only from the upper surface side or the lower surface side of the front end side, the front end side of the main body band portion 50 is elastically deformed and the entire main body band portion 50 moves, and the teeth It is possible to prevent the locked state from being released due to the tooth and the tooth being released. As a result, the binding state is strong, the stable locking state is maintained, and the binding band 10 that is difficult to come off and improved in reliability is provided.

  The lower portion of the penetrating portion 90 according to the present embodiment is formed with a lower portion of the penetrating portion lower tooth 91 that does not have the opening 31 and continues to both the auxiliary band upper surface side tooth 71 and the main body band upper surface proximal end tooth 51. Has been. For this reason, teeth are continuously formed in the longitudinal direction of the band 20 near the fastener 30 by the auxiliary band upper surface teeth 71, the penetrating portion lower teeth 91, and the main body band upper surface proximal teeth 51. . The binding band 10 according to the present embodiment is compared with the tooth in the binding state, as compared with the band 20 in which the portion where the teeth are not formed is formed in the middle of the longitudinal direction of the band 20 and the tooth formation is discontinuous. The longitudinal distribution of the applied stress can be made continuous and gentle. Thereby, it is possible to avoid stress concentration on specific teeth in the middle of the band 20 in the longitudinal direction, and it is possible to suppress breakage of the band 20 due to stress concentration.

In the present embodiment, only one fastener 30 is formed in the middle of one band 20, but the present invention is not limited to this, and two or more pieces in the longitudinal direction of the band 20 are used. The fastener 30 may be provided. If n bindings 30 similar to the above are provided in one binding band 10, the binding band 10 as a whole is obtained by being locked at the four locations as described above near each fastener 30. Thus, it is locked at a total of 4n places.
In addition, in the binding band 10 according to the present embodiment, other configurations other than those described above and the operations and effects achieved by the configurations are the same as those described in the third embodiment, and description thereof is omitted. To do.
