It has become.
JP-A-8-26327 (FIG. 1)

  However, once the conventional binding band stopper as described above is fixed, it is difficult to loosen and remove it easily when unbinding the band, and eventually the binding band is not cut with a cutter or the like. Must not. For this reason, the binding band and the binding band stopper cannot be reused and must be discarded as they are, and the binding band is not only bulky as waste, but also has a problem that it is difficult to store and dispose of it.

  The present invention has been completed based on the above circumstances, and an object thereof is to provide a binding band stopper capable of easily loosening the binding band after binding.

In the binding band stopper of the present invention, a pair of slits having a shape in which one end side of a pair of parallel straight portions is connected by a connecting line portion that is substantially perpendicular to these are provided in the plate-like member by pressing a steel plate. In addition, the connecting line portions of the slits are opposed to each other in a direction away from each other, and a groove portion extending along the connecting line portion is formed in the tongue piece portion by pressing, and the slit A circular elastic adjustment hole that is continuous with the slit is formed by pressing at the end opposite to the connection line portion of the plate-like member, and the plate-like member is separated from the plate-like member main body by the slit. Each of the tongue pieces formed in the step is elastically deformable with the end on the opposite side to the connecting line part as a rotation center, and the tongue piece part is elastically deformed and passed through the connecting line parts The command between the plate-like member main body and the tongue portion characterized in was possible pinching respectively.

  When such a binding band stopper of the present invention is used, first, the slit is widened by elastically deforming the tongue piece portion with the end portion on the opposite side to the connecting line portion as the rotation center. Then, the binding band is passed through the spread portion, and the binding band is sandwiched between the tip of the tongue piece and the plate-like member body. And the front-end | tip part of the binding band which let the slit pass is pulled, and it will be set as the state which a binding band folds in the slit to the opposite side to a tongue piece part. In this state where the binding band is folded back at a steep angle, if the binding band tries to move in the slit in the loosening direction, the tongue piece part bites into the binding band more strongly. It is clamped between the part and the plate-like member main body, and its movement is reliably prevented. When loosening the binding band, insert a finger under the binding band stopper and elastically deform the tongue piece to widen the slit. Alternatively, the entire binding band stopper is lifted so that the binding band passes through the slit at a gentle folding angle. Then, the biting force of the tongue piece portion into the binding band becomes loose, the binding band becomes easy to move in the direction of loosening in the slit, and it loosens at an acceleration with a slight movement, eventually pulling out the binding band from the slit Will be able to.

  In addition, according to the embodiment in which a pair of slits is provided and the connecting line portions of each slit are arranged to face each other in the direction away from each other, both ends of the binding band can be passed through different slits. Removal work becomes easier, and the binding band can be more stably fixed to the object to be bound.

  Further, when the binding band stopper is formed by pressing a steel plate, by providing the tongue piece portion with a groove portion extending along the connecting line portion, the gap of the slit can be appropriately secured, and consequently the tongue piece. The part can be elastically deformed without being caught. Moreover, the elastic deformation property of the tongue piece portion can be appropriately adjusted by providing an elastic adjustment hole by press working between the ends of the slit opposite to the connecting line portion.

Thus, according to the binding band stopper of the present invention, the binding band can be loosened simply by elastically deforming the tongue piece or changing the tightening posture. Can be used repeatedly.

<First Embodiment>
A first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a plan view of a binding band stopper 10 of the present embodiment. This is made of steel, and a pair of U-shaped slits 12, 12 are provided along the edge of the rectangular plate-shaped member 11 so as to face each other in the long side direction. More specifically, among the U-shaped slits 12, the pair of parallel straight portions 12A along the long side direction of the plate-like member 11 are slits having a gap of about 1 mm in width, The connecting line part 12B (along the short side direction of the plate-like member) that is connected at right angles by connecting the two is a slit having a gap of about 0.1 mm in width. A portion surrounded by the parallel straight portions 12A and 12A and the connecting line portion 12B and separated from the main body of the plate-like member 11 is a tongue piece portion 15. Further, between the ends of the parallel straight portions 12A and 12A opposite to the connecting line portion 12B, a straight groove portion 13 having a U-shaped cross section recessed by a predetermined depth is formed by pressing. (Refer to FIG. 2. Hereinafter, the recessed surface is the surface of the plate-like member 11 and the protruding surface is the back surface).

  The reason why the groove 13 is provided by press working is as follows. Since the slit gap of the connecting line portion 12B has a great influence on the holding force of the binding band, it needs to be set to an appropriate value. In the present embodiment, it was most preferable to set this to 0.1 mm, for example. However, it is extremely difficult to punch such a narrow slit into a steel sheet because of the structure of the press die. Therefore, in the present embodiment, the connecting line portion 12B is formed not by punching out the material but by shearing only by cutting the material, and at the same time, by forming the groove portion 13, the shearing portion is expanded to form a required gap. It was. When only the shearing process is performed and the groove portion 13 is not formed, burrs on both sides of the shearing portion interfere with each other, and the tongue piece portion 15 cannot be smoothly moved. For this reason, it is necessary to widen the sheared portion by the groove 13.

  In addition, elastic adjustment holes 14 having a diameter of about 3 mm that penetrate the plate-like member 11 are provided at a total of three locations, the end of the parallel straight portions 12A and 12A opposite to the connecting line portion 12B, and the center between both ends. It is provided by pressing (see FIG. 1). By appropriately setting the size of the elastic adjustment hole 14, the elastic deformability of the tongue piece 15 can be set to an appropriate value.

The binding band stopper 10 according to the present embodiment is formed by press punching, then raised to a temperature of 800 to 900 ° C. in a non-oxidizing atmosphere, and isothermally quenched in a salt bath of 300 to 400 ° C. Perform austempering. Thereby, toughness, abrasion resistance and impact resistance are improved. Thereafter, deburring is performed by shot blasting, and finally galvanization is performed as necessary.
Next, a method of using the binding band stopper 10 of the present embodiment will be described. When bundling an object to be bound W such as luggage, first, the tongue piece 15 is pressed from the back side of the binding band stopper 10 to spread the slit 12, and one end of the binding band B is slit into the slit 12. Through the connecting line portion 12B. Next, when the hand is released from the tongue piece portion 15, the tongue piece portion 15 that has been elastically deformed returns to its original position, so that the binding band B is held between the connecting wire portion 12B and the plate-like member 11 main body. (See FIG. 3).
Next, the other end portion of the binding band B is turned around the object to be bound W, and is passed through the other slit 12 of the binding band stopper 10 in the same manner as described above. When the other end portion of the binding band B is strongly pulled and tensioned, the binding band B moves in the tightening direction in the slit 12 and is strongly wound around the object to be bound W. At this time, even when the hand holding the other end of the binding band B is released and the tightening force is weakened, when the binding band B is folded at a steep angle as shown in FIGS. If the inside of the slit 12 is moved in the direction in which the binding band B is loosened, the tongue piece portion 15 strongly bites into the binding band B, so that the movement is surely prevented and the binding band B is not loosened. . When loosening the binding band B, a finger is inserted under the binding band stopper 10, and the tongue piece 15 is elastically deformed upward to widen the slit 12B. Alternatively, the binding band stopper 10 as a whole is lifted, and as shown in FIG. 5, the passing angle in the slit 12 </ b> B of the binding band B shifts to a direction orthogonal to the plate surface of the stopper 10 as compared with FIG. 3. Such an angle. Then, the biting force of the tongue piece portion 15 into the binding band B becomes gentle, and the binding band B easily moves in the direction of loosening in the slit 12B. B can be pulled out from the slit 12B.

  Thus, according to the binding band stopper 10 of the present embodiment, the tongue piece portion 15 is pressed and elastically deformed, or the passing angle in the slit 12B of the binding band B is the plate surface of the plate-like member 11. By simply tilting the binding band stopper 10 so as to be perpendicular to the binding band B, the binding band B can be easily loosened and pulled out from the binding band stopper 10, so that the binding band B does not have to be cut. The binding band and the binding band stopper can be used repeatedly.

< Reference example >
Next, a reference example of the present invention will be described with reference to FIGS. FIG. 6 is a plan view of a binding band stopper 20 according to a reference example of the present invention, which is made of plastic unlike the first embodiment, and is manufactured by injection molding. More specifically, a pair of U-shaped slits 22, 22 are provided along the edge of the rectangular plate member 21 so as to face each other in the long side direction. A portion along the side direction is a parallel straight line portion 22A, a portion connecting these one end portions and a semi-circular portion is a connecting line portion 22B, and a slit having a gap of about 0.1 mm in width as a whole It has become. A portion surrounded by the parallel straight portions 22A and 22A and the connecting line portion 22B and separated from the main body of the plate-like member 21 is a tongue piece portion 25.

  An elastic adjustment hole 24 having a diameter of about 3 mm that penetrates the plate-like member 21 is provided at the end of the parallel straight portions 22A, 22A opposite to the connecting line portion 22B. By appropriately setting the thickness of the plate-like member 21 main body and the size of the elastic adjustment hole 24, the strength and elastic deformability of the tongue piece portion 25 can be set to appropriate values.

When such a binding band stopper 20 of the reference example of the present invention is used for, for example , a binding string R having a circular cross section, first, the tongue piece portion of the binding band stopper 20 as in the first embodiment. 15 is pushed to widen the slit 22, and one end of the binding string R is passed through the connecting line portion 22 </ b> B of the slit 22. When the hand is released from the tongue piece 25, the elastically deformed tongue piece 25 returns to its original position, so that the binding string R is held between the connecting wire portion 22B and the plate-like member 21 main body. (See FIG. 7). Next, the other end portion of the binding string R is turned around the object to be bound W, and is passed through the other slit 22 of the binding band stopper 20 in the same manner as described above. When the other end portion of the binding string R is strongly pulled and tensioned, the binding string W is strongly wound and the binding string R is folded at a steep angle. As a result, the binding string R is firmly held and fixed in the slit 22 and does not loosen.

Since the binding string R is circular in cross section unlike the binding band B used in the above-described reference example , the binding string R is transverse in the slit 22 along the cut line of the connecting line portion 22B (the short side direction of the plate member 21). However, according to the binding band stopper 20 of the present embodiment, the binding band stopper 20 is held in the center of the connecting line portion 22B without being displaced. This is because the connecting line portion 22B is a semicircular slit. That is, when the elastically deformed tongue side 25 returns to the original position, the slit 22 is gradually closed from the both ends, which are the base side of the slit 22 in the connecting line portion 22B, toward the center. The connecting string R passed through the inside moves so as to be pushed toward the center. For this reason, the connection string R will finally be located in the center part of the connection line part 22B.

  On the other hand, when loosening the binding string R, a finger is inserted under the binding band stopper 20 and the tongue piece 25 is elastically deformed upward to widen the slit 22. Alternatively, the binding band stopper 20 as a whole is lifted, and as shown in FIG. 8, the angle at which the passing angle in the slit 22 of the binding string R changes to the direction orthogonal to the plate surface of the plate-like member 21. To do. Then, the biting force of the tongue piece portion 25 into the binding string R becomes gentle, and the binding string R becomes easy to move in the loosening direction in the slit 22, and it is loosened in an accelerated manner with a slight movement. R can be pulled out from the slit 22.

Thus, according to the binding band stopper 20 of the reference example of the present invention, in addition to the same effect as the above embodiment, even when the connecting string R having a circular cross section is used, the holding position thereof is the connecting line portion. There exists an effect that it can be set as the center part of 22B.
