Description

  The present invention relates to a binding tool for binding various objects to be bound, a binding fixture used for the binding tool, and a binding band. More specifically, the binding operation is easy and the binding band is effectively used. The present invention relates to a binding tool, a binding fixture, and a binding band that can be used.

  Conventionally, as a binding tool for binding an object to be bound, an annular buckle portion is integrally provided on one end side of a binding band, and the other end side of the binding band is inserted into the buckle portion, and is provided on the buckle portion. A structure in which a locking projection is locked in a locking recess or a locking hole provided on the other end side is known.

  In the binding tool configured as described above, the length of the binding band is limited, and the object to be bound is bound within an allowable range, so that the peripheral length of the object to be bound is slightly longer than the length of the binding band. It cannot be handled. That is, there is a problem that the applicable range of the object to be bound is small. In addition, when the peripheral length of the object to be bound is short, there is a problem that there is a lot of waste of cutting and removing an excessive part on the other end side of the binding band that protrudes greatly from the buckle part.

Moreover, the thing of the structure provided with the binding band and the fixing tool separately as a conventional binding tool is also known (for example, refer patent document 1).
Japanese Utility Model Publication No. 5-73387

  The configuration of the binding tool described in Patent Document 1 is a configuration as shown in FIG. That is, flexible first and second ratchet claws 103 and 105 having opposite directions are provided inside the cylindrical fixture body 101. A space 107 that allows the first ratchet pawl 103 to bend is formed between the first ratchet pawl 103 and the upper wall portion of the fixture main body 101, and the first and second ratchet pawls are formed. A first passage 111 for inserting the binding band 109 is formed between 103 and 105. Further, a second passage 113 is formed between the second ratchet pawl 105 and the lower wall portion of the fixture main body 101.

  In the above configuration, in order to form the binding band 109 in a loop shape for binding the object to be bound 115, first, the first passage 111 is lifted by lifting the tip end side of the first ratchet pawl 103 using an appropriate jig. Increase the vertical spacing of. Then, the binding band 109 is formed in a loop shape by inserting the distal end portion 109A of the binding band 109 in the direction of arrow A and inserting the distal end portion 109A in the direction of arrow B with respect to the second passage 113. is there.

  In the above configuration, by pulling the binding band 109 formed in a loop shape in the direction opposite to the arrow A, the object to be bound 115 in the loop can be firmly tightened. Further, by cutting the binding band 109 outside the fixture main body 101, waste of the binding band 109 can be eliminated.

  However, in the above configuration, when the binding band 109 is inserted in the direction of the arrow A with respect to the fixture main body 101, it is necessary to lift the tip portion of the first ratchet pawl 103 with a jig, so that the operability is improved. There is a problem. Moreover, in the said structure, the upper wall part of the fixing tool main body 101, the space part 107, the 1st ratchet nail | claw 103, the 1st channel | path 111, the 2nd ratchet claw 105, the 2nd channel | path 113, and the lower wall part of a fixing tool main body are included. Since it is the structure which overlapped in the up-down direction, there exists a problem that the vertical dimension of the whole structure of the fixing tool main body 101 becomes large.

  Furthermore, in the said structure, the 2nd ratchet nail | claw 105 exists between the 1st channel | path 111 and the 2nd channel | path 113 which penetrate the binding band 109, and is a substantial partition. That is, since it is a two-layered independent space and independent mechanism, the configuration is complicated and it is difficult to manufacture with a mold or the like.

  The present invention has been made in view of the conventional problems as described above, and the binding fixture allows the movement of the band in the opposite direction on the opposed inner surfaces of the cylindrical fixture body, but the return direction. It has a ratchet claw for preventing movement of the band to.

  Further, in the binding fixture, the operation area of each ratchet claw is arranged on the entrance / exit side of the fixture body.

  In addition, the binding band is provided with a locking projection having an inclined surface in one direction on the surface of the band main body at an appropriate pitch, and is locked on the back surface of the band main body in a direction opposite to the direction of the locking projection. Protrusions are provided at appropriate pitches.

  Further, the binding band is characterized in that bank belts are provided on both sides of the band main body.

  A binding fixture having ratchet claws for allowing movement of the binding band in opposite directions on the opposing inner surfaces of the cylindrical fixture body, but preventing movement of the binding band in the return direction; And a binding band that forms a loop by being inserted twice from the same direction into the entrance of the fixture, and locking protrusions that are locked by the ratchet claws on both sides of the binding band are provided at appropriate pitches. It is characterized by this.

  Bundling fixtures with metal ratchet pawls on the opposing inner surfaces of the cylindrical fixture body that allow movement of the binding bands in opposite directions but prevent movement of the binding bands in the return direction And a binding band that forms a loop by being inserted twice from the same direction into the entrance of the fixture, and the ratchet claw bites into the binding band.

  According to the present invention, when the distal end portion of the binding band is first inserted into the fixture main body, the interval between the first and second ratchet claws is large, and the binding band can be easily inserted. And, when the binding band is formed in a loop shape and the tip of the binding band is inserted for the second time from the same direction, since the binding bands overlap, the first and second ratchet claws are bent, The binding band can be easily inserted into the fixture main body.

  Further, in the state in which the binding band is formed in a loop shape, the binding band is in a state of being in direct contact and overlapping in the fixture main body, and the height dimension of the overall configuration of the fixture main body is suppressed to be small. Is something that can be done.

  Referring to FIG. 1, the binding tool 1 according to the embodiment of the present invention allows the movement of the binding band 5 in the opposite direction on the opposed inner surfaces of the cylindrical fixture body 3, but in the return direction. A binding fixture 11 including first and second ratchet claws 7 and 9 for preventing movement of the binding band 5 is provided.

  As shown in FIG. 2, the fixture main body 3 in the binding fixture 11 is formed in a cylindrical body having a quadrangular through hole 13, and the first and second ratchet claws 7, 9. Are provided symmetrically on the inlet side and the outlet side of the through-hole 13. That is, the first and second ratchet claws 7 and 9 are provided apart from the entrance / exit side of the through-hole 13 so that their operation regions do not overlap each other. Since the first and second ratchet claws 7 and 9 are symmetrical, the through hole 13 in the fixture body 3 is not fixed at the entrance and exit, and if one side becomes the entrance, the other side becomes the exit. It will be.

  The first and second ratchet pawls 7 and 9 are inclined so that the tip portions (free ends) are directed toward the center side of the through-hole 13. Locking claws 15 that can freely lock the locking protrusions provided in the binding band 5 are formed. A concave portion 17 into which each ratchet claw 7, 9 can enter is formed in the fixture main body 3 corresponding to each ratchet claw 7, 9.

  The height of the through-hole 13 in the fixture main body 3 is formed to be slightly larger than the thickness of the binding band 5 and the both sides of the through-hole 13, that is, the first and first dimensions. On both sides of the two ratchet claws 7, 9, belt guide portions 19 for guiding the bank belts 21 provided on both sides of the binding band 5 are formed.

  As shown in FIG. 3, the binding band 5 includes bank belts 21 having smooth surfaces on both sides in the longitudinal direction. The bank belt 21 constitutes a bank-like portion on both sides of the binding band 5 and is formed thick. Then, between the bank belts 21 on the surface of the binding band 5, locking projections 25 having inclined surfaces 23 in one direction are provided at appropriate pitches. And the latching protrusion 25 with which pitch was suitably provided in the back surface of the said binding band 5 is formed in the direction opposite to the directionality of the said latching protrusion 25 of the surface.

  In the configuration as described above, in order to form the binding band 5 in a loop shape in order to bind the objects to be bound (not shown), first, the front end portion 5A of the binding band 5 is connected to the through hole 13 of the fixture main body 3. On the other hand, it is inserted in the direction of arrow A in FIG. 1 (first insertion). At this time, the first ratchet pawl 7 protrudes into the through-hole 13, but the binding band 5 is single, and the first and second ratchet pawls 7 and 9 are unevenly distributed on the entrance / exit side of the through-hole 13. Therefore, the first and second ratchet claws 7 and 9 can be easily inserted without being locked by the locking claws 15.

  Next, the binding band 5 is formed in a loop shape, and the distal end portion 5A of the binding band 5 is inserted into the through hole 13 in the fixture main body 3 from the same direction (second insertion). The locking projection 25 is locked by the locking claw 15 in the second ratchet 9 and cannot be removed.

  As described above, when the distal end portion 5A of the binding band 5 is inserted into the through hole 13 of the fixture body 3 for the second time, the binding band 5 overlaps in the through hole 13 twice. At this time, the portions of the thick bank belts 21 on both sides of the binding band 5 overlap with each other in the belt guide portion 19 of the through-hole 13, so that the locking protrusions 25 respectively provided on the front and back surfaces of the binding band 5 are mutually attached. There is no such thing as interference. Therefore, the insertion of the tip portion 5A into the through hole 13 can be performed relatively easily.

  As described above, when the binding band 5 is doubled in the through hole 13 in the fixture main body 3, the locking protrusions 25 provided on both the front and back surfaces of the binding band 5 are engaged with the first and second ratchet claws 7 and 9. It is in a state of being locked to the pawl 15. In this state, when the binding band 5 is pulled in the direction opposite to the arrow A so as to fasten the object to be bound located in the loop of the binding band 5, the first ratchet 7 is bent by the first ratchet 7 being bent. The locking projections 25 of the binding band 5 are pulled out to the outside every pitch beyond the locking claw 15.

  As described above, when the binding band 5 is pulled in the direction opposite to the arrow A, the locking protrusion 25 in the vicinity of the front end portion 5A of the binding band 5 is locked by the locking claw 15 in the second ratchet claw 9. Yes, the tip 5A of the binding band 5 does not come out of the through hole 13 of the fixture body 3. In the state where the binding band 5 is pulled and the object to be bound is tightened, the locking claw 15 of the first ratchet claw 7 locks the locking projection 25 of the binding band 5 to prevent loosening. Therefore, after the object to be bound is tightened, the excess portion of the binding band 5 can be cut.

  As can be understood from the above description, according to the present embodiment, when the distal end portion 5A of the binding band 5 is inserted into the through hole 13 in the fixture body 3, there is no interference from the ratchet claw on the inlet side. It can be easily inserted. Further, the fixture main body 3 has a configuration in which the ratchet claws 7 and 9 are respectively provided on the entrance and exit sides of the through holes 13 having a height slightly larger than the dimension in which the binding bands 5 are doubled. Can be simplified and the height can be reduced.

  FIG. 4 shows a second embodiment. In the second embodiment, the tops of the locking projections 25 provided on both the front and back surfaces of the binding band 5 are formed in a shape having a substantially right angle, and the first and second ratchet claws 7 and 9 are connected to the base side. Is constituted by a metal plate or the like embedded in the fixture body 3 and projecting obliquely. Even in this case, the same effects as those of the above-described embodiment can be obtained.

  By the way, the first and second ratchet claws 7 and 9 are made of metal and provided with an edge having an appropriate shape such as a saw blade shape or a knife edge shape, that is, a shape that easily bites into the binding band 5. With this configuration, when the object to be bound is tightened, the tip portions of the ratchet claws 7 and 9 bite into the binding band 5 to prevent loosening. Therefore, in this case, the locking projections 25 provided on both surfaces of the binding band 5 can be omitted, and the binding band 5 can be configured as a flat belt.

  The ratchet claws 7 and 9 are allowed to move in one direction of the binding band 5 but only have a function of preventing movement in the other direction (relaxing direction).
